Bone and Joint Infections

S. aureus is the most common pathogen in osteomyelitis, septic arthritis, and prosthetic joint infections. Mortality for bone and joint infections is typically not very high however, morbidity and long-term functional impairment is. Management consists of a combination of surgery to remove devitalized bone and prolonged intravenous (IV) antibiotic therapy, typically for 6 weeks. Limited high-quality data exists with antimicrobial therapy used for bone and joint infections, and therefore it is nearly impossible to make evidence-based recommendations. Our antibiotic recommendations are shown in Table 6.

Arthritis An Inflammation of the Joints

We are rarely conscious of our joints, and frequently take for granted their amazing ability to keep our bodies moving without noticeable pain or friction. But this is certainly not the case for people afflicted with arthritis (arth-RYE-tis) Arthritis is an inflammation of (-itis) the joints (arthr), usually accompanied by pain and swelling. Two representative types are osteoarthritis (ahs-tee-oh-ar-THREYE-tis) and rheumatoid (ROO-mah-toyd) arthritis. Osteoarthritis, the most common form of arthritis, gets part of its name from the degenerative (dee-JEN-er-ah-tiv) changes that occur within the Organ 3 inflamed joints. The articular (ar-TIK-you-lar) cartilage at the ends of bones, helping to form the ''joint'' (articul), is frequently broken down. There are secondary, pathological changes, such as an abnormal increase in size, within the ''bone'' (osteo) tissue underlying the joint. (This explains the first part of the name, osteoarthritis). Osteoarthritis (abbreviated as OA) is common...

Rheumatoid Arthritis and Osteoarthritis

Rheumatoid arthritis was an early target in many MMP-inhibitor development programs. The disease is characterized by the destruction of the articular cartilage and underlying bone. MMP levels are elevated in effected joints (109) and MMP inhibitors have been shown to be effective in models of the disease (84). Similar relationships appear to exist for osteoarthritis (34,110). MMP inhibitors may also be active in these models by virtue of their ability to inhibit the cellular processing of tumor necrosis factor-a (TNF-a), mediated by the recently identified metalloproteinase disintegrin (22,23). Antibodies to TNF-a have been shown to give symptom relief in patients with rheumatoid arthritis (111). Several companies have developed MMP inhibitors for the treatment of rheumatoid arthritis, and trials with two compounds, Ro 32-3555 (15 Roche) (112) and D5140 (Chiroscience), have started. More recently trials with D5140 have been curtailed because of insufficient oral absorption.

Rheumatoid Arthritis309

Rheumatoid arthritis is a chronic autoimmune disease in which the immune system attacks the synovial tissue, the membrane that lines the joints. It is the second most common form of arthritis and usually appears between ages 20 and 40. Although the cause of rheumatoid arthritis is unknown, there is a genetic component if a close relative is affected, you are more likely to develop the disease. There is no known cure. In rheumatoid arthritis, the fluid that lubricates the joints contains irritating chemicals that attack and damage the surfaces of the joints. The inflamed membrane swells and thickens, causing a wearing away of the joint cartilage, which leads to erosion of the bone and weakening of supporting tendons, ligaments, and muscles. The small joints in the hands, wrists, feet, ankles, and neck are most frequently affected, but the hips and the knees also can be affected. In most cases, more than one joint is affected and usually the same joints are affected on both sides, such...

Rheumatoid arthritis

Rheumatoid arthritis is the single most common autoimmune disease in man. The principal manifestations are periarticular soft tissue swelling and joint stiffness and pain. Despite significant progress in our knowledge of the disease, there is still no cure for rheumatoid arthritis. For more information about the clinical aspects of this disease, see References 18 and 29. This disease is a complex one involving an IgM and IgG autoantibody (called rheumatoid factor), with subsequent tissue damage caused by immune complex deposition. Rheumatoid factor is present in the serum of most adult patients. Rheumatoid factor is in reality an autoantibody reacting with the Fc portion of human IgG. The occurrence of the rheumatoid factor is rather confusing, as it can be found not only in rheumatoid arthritis or systemic rheumatic disease, but also in hypergammaglobulinemic patients, or even in healthy persons. Three classes of rheumatoid factor can be found IgM, IgA, and IgG.20 Despite the fact...

Adalimumab Rheumatoid Arthritis [610

Adalimumab is the first fully human neutralizing IgG1 monoclonal antibody specific for TNF-alpha and is the third TNF sequestrant marketed. It was launched in US, UK and Germany for the treatment of rheumatoid arthritis. It prevents TNF binding to p55 and p75 cell surface TNF receptors thereby decreasing leukocyte migration and acute phase reactants such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and levels of serum IL-6, MMP-1 and MMP-3. Adalimumab was developed starting with a phage-display derived murine antibody, followed by replacement of both heavy and light chains with human forms and further optimization to yield the final humanized form. In receptor binding studies, adalimumab exhibits an IC50 between 7.8 X 1011 and 15.6 X 1011 M with a Kd of 1 X 1010M. It also binds to pro-TNFalpha on cell membranes mediating complement-dependent toxicity and to the Fc receptor mediating antibody-dependent cytotoxicity. In a human-TNF transgenic polyarthritis mouse...

Leptin in rheumatoid arthritis

AIA is a model of immune-mediated joint inflammation induced by administration of methylated bovine serum albumin (mBSA) into the knees of immunized mice (21). The severity of arthritis in leptin- and leptin receptor-deficient mice was reduced in this model (22). The milder form of AIA seen in ob ob and db db mice, as compared with their controls, was accompanied by decreased synovial levels of interleukin (IL)-1P and TNF-a, decreased proliferative response to antigen of lymph node cells in vitro, and a switch toward production of Th2 cytokines (22). Serum levels of all isotypes of anti-mBSA antibodies were significantly decreased in arthritic ob ob mice as compared with controls. Thus, in AIA leptin probably contributes to joint inflammation by regulating both humoral and cell-mediated immune responses. However, joint inflammation in AIA depends on the adaptive immune response, which is known to be impaired in ob ob and db db mice, so recent studies investigated the effect of leptin...

Osteoarthritis

Obesity is strongly associated with an increased risk of osteoarthritis. This has been particularly studied and confirmed for knee osteoarthritis. Analyses of the National Health and Nutrition Examination Survey data show that adults in the United States with a BMI > 30 have a more than fourfold higher prevalence of radiographic knee osteoarthritis than those with a BMI lower than 30 (58). In one study (59), the risk of developing both radiographic and symptomatic knee osteoarthritis was increased in elderly men and women who were obese for an average of 37 yr. The risk of developing disabling knee osteoarthritis over a 10-yr period is strongly and directly correlated with initial BMI (60). Weight loss is recommended for overweight persons with knee osteoarthritis under the American College of Rheumatology treatment guidelines (61). Several studies suggest that weight loss may prevent the development or worsening of knee and hip osteoarthritis. In an observational study, Felson et...

Arthritis

Collagen-induced arthritis (CIA) in rodents is an accepted model for rheumatoid arthritis (RA) in man. Two injections of type II collagen separated by 21 days results in the onset of a classic Th1 lymphocyte driven arthritis inflammation becomes apparent 5-10 days after the second dose of collagen. The ability of simvastatin to modulate the disease process was tested in both a prophylactic protocol, where the drug treatment started before the second dose of collagen, and in a therapeutic protocol, where the drug was administered after the development of the arthritis 93 . In both cases, simvastatin suppressed the incidence and severity of the arthritis. In the therapeutic group, a significant reduction in arthritis progression was observed with 3 days of starting treatment. In both groups, plasma levels of IL-6 were significantly reduced. The studies demonstrated that simvastatin specifically suppressed Th1 cytokine (TNFa, IL-12 and IL-6) responses to collagen and the serum levels of...

When to Stop Exercising

Exercise provides many health benefits, but it is important to know when to stop exercising. If you feel any unusual symptoms, such as difficulty breathing, joint pain, dizziness, chest pain, or an irregular heartbeat, stop exercising immediately. Although regular exercise can reduce your risk of heart attack and early death from heart disease, overexercising can also bring on a heart attack, especially in sedentary men who have one or more risk factors for heart disease (see page 204). Become familiar with the warning signs of a heart attack so you recognize them if they ever occur in yourself or in someone else. The most common warning signs of a heart attack include

Avian nephritis virus 1 to 3 ANV1 to

Avian orthoreovirus (ARV) Species in the genus Orthoreovirus which do not infect mammalian species and share a common group antigen, distinct from the mammalian reovirus group antigen. The genome consists of 10 segments of double-stranded RNA. Unlike mammalian orthoreoviruses, infectivity is not increased by heating in the presence of MgCl2. There are at least 11 distinct serotypes. The viruses all induce syncytia in cell culture and cause a variety of symptoms in chickens and turkeys following a viremia which results in widespread virus dissemination. The principal site of replication is the gastrointestinal tract, and the most serious disease symptoms are arthritis (tendosyn-ovitis) caused by infection of the tendons and associated tissues of the hock joint. Other symptoms, which vary depending upon the strain of virus, include hepatitis, gastroenteritis, myocarditis, and paling and weight loss due to maladsorption. The virus is widespread in commercial poultry flocks, but some...

Banna virus ChinaHN59 BAVHN59V

Barmah Forest virus (BFV) A species in the genus Alphavirus related genetically to Ross River virus, but not antigenically related to other alphaviruses. First isolated in 1974 from mosquitoes, Culex annulirostris, collected in the Barmah Forest, Victoria, Australia. Shown to cause a clinical disease, Barmah Forest disease, indistinguishable from Ross River virus infection in humans, who present with a rash, fever and malaise sometimes with arthritis arthralgia. Marsupials are likely primary hosts, and the virus has been isolated from a wide variety of mosquito species. Barmah Forest disease became notifiable in Australia in 1995. The virus grows well in the C6 36 mosquito cell line.

Describe the examination of the neck

It is also important to have the patient demonstrate the range of motion of the head and neck. Preparation for laryngoscopy requires extension of the neck to facilitate visualization. Elderly patients and patients with cervical fusions may have limited motion. Furthermore, patients with cervical spine disease (disk disease or cervical instability, as in rheumatoid arthritis) may develop neurologic symptoms with motion of the neck. Radiologic views of the neck in flexion and extension may reveal cervical instability in such patients.

Clinical implications

Experiments were performed in transgenic animals, they could similarly be used in viral vectors to direct endothelial-specific gene expression. Potential therapeutic uses of these vectors include the expression of modulators of inflammation or cell growth in diseases such as the restenosis associated with angioplasty, vasculopathy related to cardiac transplantation, and chronic inflammation associated with atherosclerosis. An example of a protein that has been successfully used to treat restenosis is the Fas ligand, which promotes cell death (56). However, if this gene was expressed in nonvascular cells, it could lead to significant adverse effects. In addition to inflammatory conditions, a vascular-specific promoter might also be used to block vascular growth during tumor growth, since most endothelial cells are not actively proliferating. The identification of transcription factors that may serve as master switches of endothelial differentiation or angiogenesis may also allow the...

M0 That Fail To Switch From A Proangiogenic To An Angioinhibitory Phenotype Contribute To Pathological Angiogenesis

Macrophages have been recognized as important angiogenesis effector cells for a number of years (48-50). They have been shown to actively participate in the initiation and maintenance of wound neovascularization, where they produce a spectrum of soluble mediators capable of stimulating the growth and migration of microvascular endothelial cells. They have been shown to function during the process of tumor angiogenesis to augment both tumor growth and neovascularization (51,52). Also, the persistent and unrelenting formation of granulation tissue that is a feature common to chronic inflammatory diseases, such as rheumatoid arthritis and psoriasis, are examples in which the destructive effects of persistent granulation tissue and aberrant angiogenesis are caused in large part by the promiscuous angiogenic activity of M0 (52).

Box 33 Immune Modulators and Fungal Infections

The immune system is powerful, and sometimes it goes astray. For example, rheumatoid arthritis, a painful swelling of joints, involves the excessive action of tumor necrosis factor-a an important protein component of the immune system. Anti-inflammatory agents, such as corticosteroids, relieve the symptoms of arthritis. But they also weaken the defense against fungi. Because the current medicines never actually cure arthritis, they must be taken for life. That makes fungal infection a constant threat.

Who gets osteoporosis

Children, adolescents, and young adults can get osteoporosis too, particularly those with genetic or nutritional disorders, and eating disorders such as anorexia nervosa and bulimia, because they do not make hormones or absorb calcium, Vitamin D, and other nutrients and protein required for normal bone development. Those who are treated with medications that interfere with bone development may also get osteoporosis. People who are treated with long-term methotrexate (> 1 month), usually for cancer or arthritis, are more at risk. Long-term use of the gonadotropin-releasing hormone analogs, such as Lupron, for the treatment of endometriosis in young women can contribute to the development of osteoporosis as well. And the most common class of medication to cause osteoporosis or osteopenia at any age is corticosteroids, used for such problems as lupus, arthritis, or asthma. Osteoporosis occurring after taking a glucocorticoid is so common that it has its own name glucocorticoid-induced...

Leptin and pathophysiology of the immune system

Recent data also suggest the possible role of leptin in the pathophysiology of some autoimmune diseases. This has already been demonstrated in some animal models, such as the experimental autoimmune encephalomyelitis, antigen-induced arthritis, models of type 1 diabetes, autoimmune colitis, and experimental hepatitis, as well as some clinical studies (15,17,72-74). However, this is the subject of other chapters in this book, and we are not reviewing the possible role of leptin in the pathophysiology of immune diseases.

Biology and Chemistry of MMPs and TIMPs

Interstitial collagenase, the first MMP family member identified, was discovered in experiments designed to explain collagen remodeling in the metamorphosis of a tadpole into a frog (G12). Since collagens represent the major structural proteins of all tissues and the chief obstacle to cell migration, it has long been postulated that collagenolytic enzymes play pivotal roles in facilitating dissemination of cancer and in the pathogenesis of rheumatoid arthritis. A pathological role for MMPs in cancer, arthritis, skin disease, and nonhealing wounds was suggested in the 1980s. Later interest has focused on the role of MMPs in cardiovascular remodeling (such as atherosclerosis, restenosis), aortic aneurysms, congestive heart failure, and diseases of the lung, liver, central nervous system, retina, and kidney (G2).

Capping See capped terminus

Caprine arthritis encephalitis virus (CAEV) A species in the genus Lentivirus. A non-oncogenic retrovirus causing a disease complex first described in 1974 that affects goats of all ages and breeds. In young animals, paresis and paralysis result from infection, but in older animals there is chronic persistent arthritis and mastitis. Concomitant bacterial and parasitic opportunistic infections are common. The virus is widely disseminated in goat herds in North America, Europe and Australia, especially in dairy goats where kids are commonly fed pooled colostrum and milk from dairy mothers which disseminates the infection. The CAEV genome is 9.2kb in length and exists in the virion as a dimer. The primer for DNA synthesis is tRNALys1,2. In addition to gag, pol and env genes, the genome encodes three proteins Q (230 amino acids) which is analogous to vif of HIV tat (87 amino acids) which activates viral transcription and rev (33 amino acids) which is involved in transportation of genomic...

The Tissue Kallikreins in the Context of Other Serine Proteases in the Human Genome

Serine proteases (SP) are a family of enzymes that use a uniquely activated serine residue in the substrate-binding pocket to catalytically hydrolyze peptide bonds 66 . SP carry out a diverse array of physiological functions, of which the best known are digestion, blood clotting, fibrinolysis, fertilization, and complement activation during immune responses 67 . They have also been shown to be abnormally expressed in many diseases including cancer, arthritis, and emphysema 42, 43, 67-70 .

Role of obesity and body fat distribution in cardiometabolic risk

Complications which seem to affect every major organ system (Table 3.2). Specifically, obesity increases an individual's risk for cancer, gastrointestinal diseases, arthritis, and adversely affects psychological well-being. However, the major concern, as described in detail in this Atlas, is the markedly increased risk to develop diabetes and cardiovascular disease in those individuals who are obese. Specifically, obesity is significantly associated with both the traditional risk factors, i.e. hypertension, dyslipidemia, diabetes, and the non-traditional risk factors, i.e. fibrinogen and inflammatory markers, of cardiovascular disease. In addition,

Ramanan Laxminarayan and Martin L Weitzman

From an economist's perspective, the treatment of infectious diseases is fundamentally different from the treatment of noninfectious conditions such as arthritis, cardiovascular disease, or cancer. Unlike the case of noninfectious or chronic diseases, two social externalities one positive and the other negative inherently characterize the treatment of infectious diseases. Take the case of antibiotics (although the situation can be generalized to antivirals and antimalarials as well). On the one hand, antibiotic treatment cures the patient, thereby preventing the disease from being transmitted to other individuals. On the other hand, drug treatment selects in favor of harmful mutations or organisms that are resistant to the drug, increasing the likelihood that the drug will be less effective in the future. Because the individual patient fails to take into account either of these externalities when deciding to seek treatment, a Pigovian tax or subsidy of treatment could in principle...

COX2Specific Inhibitors

Pharmacologists took advantage of subtle differences in the active sites of the two forms of COX to develop molecules (celecoxib, rofecoxib) that are highly selective inhibitors of COX-2. At doses employed in clinical practice, these agents do not affect COX-1 and thus are specific COX-2 inhibitors (20). As would be predicted, these drugs, even at very high doses, spare GI prostaglandins. When studied with endoscopy, both celecoxib and rofecoxib produce rates of erosions nearly equivalent to placebo (22,23). Rofecoxib has also been shown to be equivalent to placebo in fecal blood loss and intestinal permeability studies in humans. Clinical trials have demonstrated antiinflamma-tory efficacy of COX-2-specific inhibitors equivalent to that of commonly used NSAIDs in arthritis patients (22). COX-2-specific inhibitors have been associated with low rates of serious GI complications in large clinical outcome trials, as discussed in detail below.

Prevention And Treatment Of Dyspepsia Associated With Nsaid

Dyspepsia and heartburn are common symptoms among patients who take NSAIDs. They occur daily in approximately 15 of those taking these medications. Within a 6-month period, 5-15 of rheumatoid arthritis patients discontinue a given NSAID because of dyspeptic side effects (1). Symptoms lead to expenditures for administration of cotherapy with antiulcer medications and referrals for endoscopy. Symptom-driven costs are a substantial, albeit poorly quantified, component of the total cost of NSAID therapy.

Basic Laboratory Research

Oxidative processes may play an important role in the pathogenesis of many chronic diseases, including atherosclerosis, cancer, arthritis, eye disease, and reperfusion injury during myocardial infarction (MI). Data from in vitro and in vivo studies suggest that oxidative damage to low-density lipoprotein (LDL) promotes several steps in atherogenesis,7 including endothelial cell damage,8,9 foam cell accumulation,1012 and growth13,14 and synthesis of autoantibodies.15 In addition, animal studies suggest that free radicals may directly damage arterial

Role of PARP1 and PAR Polymer in Excitotoxicity

(D'Amours et al. 1999 Virag and Szabo 2002). PARP-1 is considered a genome guardian, because it takes part in DNA repair under physiological conditions (Jeggo 1998 Poirier et al. 1982). Under mild genomic stress, PARP-1 is activated to induce DNA repair, whereas severe cell stress induces massive PARP-1 activation that ultimately leads to cell death (Virag and Szabo 2002). Both gene deletion and pharmacological inhibition studies have shown that PARP-1 activation plays a key role in cytotoxicity following ischemia reperfusion, neurodegeneration, spinal cord injury, ischemic injury in heart, liver, and lungs, and in retinal degeneration, arthritis and diabetes (Virag and Szabo 2002). In the nervous system, massive PARP-1 activation is triggered by excitotoxic stimuli. It was originally presumed that cell death in PARP-1 toxicity was induced by the intracellular energy depletion from PARP-1's use of NAD+ (Virag and Szabo 2002). NAD+ is an important cellular molecule for many...

Serological Diagnosis of CD

Serological diagnosis is based on estimation of antibodies against gliadin and of autoantibodies directed against tTG. Gliadin antibodies have been known for more than 40 years 91 . However, their diagnostic sensitivity and specificity for CD is low. The immunoglobulin A (IgA) class has a somewhat higher specificity than the immunoglobulin G (IgG) class 88 . Increased concentrations of gliadin antibodies can also be found in a variety of other conditions not related to CD, for example inflammatory bowel disease 92 , IgA nephropathy 93 , HIV infection 94 , rheumatoid arthritis 95 , as well as in some apparently normal individuals. Furthermore, gliadin antibodies were also described in neurological disorders 96, 97 . The most frequently published neurological syndromes associated with gliadin antibodies are cerebel-lar ataxia (gluten ataxia) and peripheral neuropathy (celiac neuropathy). However, the association between gliadin antibodies and neurological diseases is, for the most part,...

Angiogenesis Associated with Other Pathological Conditions

Two independent studies have suggested that VEGF is involved in the pathogenesis of rheumatoid arthritis (RA), an inflammatory disease in which angiogenesis plays a significant role (178,179). The RA synovium is characterized by the formation of pannus, an extensively vascularized tissue that invades and destroys the articular cartilage (180). Levels of immunoreactive VEGF were found to be high in the synovial fluid of RA patients they were very low or undetectable in the synovial fluid of patients affected by other forms of arthritis, or by degenerative joint disease (178,179). Furthermore, anti-VEGF antibodies significantly reduced the endothelial cell chemotactic activity of the RA synovial fluid (178).

Alternative Indications For Dpp4 Inhibitors

Numerous studies suggest DPP4 inhibition for pharmacological uses other than the restoration of glycemic control and type 2 diabetes. The common underlying hypotheses of these studies are divided into two categories that describe fundamental properties of DPP4. CD26, a membrane-associated peptidase that has DPP4 activity has been extensively studied in relation to its role in regulating T-cell physiology. As such, DPP4 activity has been studied in the context of T-cell activation and immune function 92 . Activated T-cells are known to have increased cell-surface expression of DPP4 93 . Furthermore, cytokines such as RANTES, SDF-la, MCP-2, and TNF-a have all been characterized as substrates for DPP4, so it is a reasonable hypothesis that DPP4 plays an immunomodulatory role 94 . However, recent studies have raised questions on the dependence of DPP4's pro-teolytic activity to T-cell activation and other functions such as proliferation and cytokine release. In a study using compounds...

DIHYDRO1Hbenzopyrano[34fQuinolines Dbq

The dihydro-1H-benzopyrano 3,4-f quinolines (DBQ) scaffold has received considerable drug discovery attention aimed at developing versatile hormone receptor ligands. An advanced compound in this class, AL-438 (34), was the first dissociated GR agonist to show a spectrum of in vivo anti-inflammatory activity while attenuating the side effect profile 44 . Briefly, 34 is a potent and selective GR ligand (GR Ki 2.5 nM) exhibiting cellular dissociative behavior in TR (IL-6 inhibition in human skin fibroblast) compared to TA (TAT in HepG2 cells, osteocalcin inhibition in MG63 cells and aromatase induction in HSF cells) assays. In addition, 34 displays steroid-like anti-inflammatory activity in vivo (rat carrageenan-paw edema (CPE) ED50 11 mg kg rat adjuvant-induced arthritis (AIA) ED50 9 mg kg). Reduced side effects (bone metabolism and glucose regulation) in rats are seen with 34 when compared with prednisolone at equivalent anti-inflammatory doses. Further SAR studies of 34 reveal that...

Keratoconjunctivitis Sicca

Keratoconjunctivitis sicca is a dry eye syndrome commonly associated with an underlying systemic autoimmune disorder such as Sjogren's syndrome, rheumatoid arthritis, or HIV infection. However, it must be included in the differential of ocular allergy, especially in perimenopausal and postmenopausal women. Tear production decreases with age 60 fewer than at the age of 18. The eye produces approx 400 drops of tears per day. It is characterized by an insidious and progressive lymphocytic infiltration into the main and accessory lacrimal glands. Patients initially complain of a mildly injected eye with excessive mucus production. Symptoms include a gritty, sandy feeling in the eyes compared to the itching and burning feeling many patients complain of with histamine release into the eye. As the cornea becomes involved, a more scratchy and painful sensation as well as photophobia may appear. The corneal epithelial injury can be detected with punctuate staining with fluorescein. The...

The Role Of Neuropsychiatric Assessment In Diagnosis Of Parkinsonian Disorders

Is depression more prevalent in PD compared to other conditions with comparable functional impairment If not, there is little reason to assume a disease-specific association between PD and depression. Studies of this question have usually included small samples subject to selection and participation biases. Nilsson et al. used the Danish registers of somatic and psychiatric in-patients to address this question. Data from more than 200,000 persons were analyzed, and more than 12,000 subjects with PD were identified. A significant increased risk for hospitalization owing to depression in patients with PD compared to subjects with osteoarthritis or diabetes mellitus was found, and the authors suggest that the increased risk was not a mere psychological reaction to the disease, but rather because of disease-specific brain changes in PD patients (56).

Mitochondrial Dysfunction in Lupus T Cells

SLE T cells exhibit both defective AICD and enhanced spontaneous apoptosis (Table 1). Coordinate mitochondrial hyperpolarization and ATP depletion play key roles in abnormal T-cell death of patients with SLE (36), AWm and ROI levels as well as cytoplasmic pH are elevated in patients with SLE in comparison to healthy or controls with rheumatoid arthritis (36,37). Baseline mitochondrial hyperpolarization and ROI levels correlated with diminished GSH levels, suggesting increased utilization of reducing equivalents in patients with SLE.

Bcells in autoimmuneinflammatory disease

Autoimmune and inflammatory diseases remain an area of significant unmet medical need. B-cells are critical regulators of immune responses and are implicated in the pathogenesis of conditions such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS), and immune thrombocytic purpura (ITP) 1-4 . Principal among B-cells contribute to the initiation and progression of inflammatory arthritis by three main mechanisms 8,9 . First, B-cells are highly efficient antigen-presenting cells that provide the signals necessary for T-cell activation 10,11 . Once activated by B-cells, T-cells produce proinflammatory cytokines such as tumor necrosis factor a (TNFa) and interleukin (IL)-1 that perpetuate the inflammatory process. Second, autoreactive B-cells produce pathogenic autoantibodies, such as RF and anti-cyclic citrullinated peptide (anti-CCP) antibodies, which are diagnostic and prognostic markers of disease 12,13 . RF immune complexes within the synovium can...

Clinical Implications of Leptin Physiology in the Elderly

In recent years, investigators have hypothesized that leptin may be involved in the pathogenesis of chronic disease states including diabetes, metabolic syndrome, dyslipidemia, anorexia, and malnutrition as well as hypertension, atherosclerosis, osteoporosis, and osteoarthritis 2-5 . Although these diseases are highly prevalent in old age, existing data on the role of leptin in a specific disease state has not been unequivocal. Furthermore, the available literature data were not always obtained in an elderly population. Because of this limitation, the second part of the review addresses those diseases in which the role of leptin has been supported by relevant and unequivocal findings from data collected in elderly populations.

Role in skeletal pathophysiology

Bone protection is a salient feature of FMS inhibitor pharmacology. Anti-FMS antibody blocked completely the otherwise fulminate osteo-clastogenesis and bone erosion in a murine KRN-serum transfer arthritis model 19 . Four structurally unrelated oral FMS inhibitors have provided dramatic protection to bone in murine models of collagen- or adjuvant-induced arthritis 20-23 . FMS inhibitors, tested in models of metastatic bone disease, reduced radiographic lesions 24 . These data provide the preclinical rationale for evaluating FMS inhibitors in RA and metastatic bone disease. Pfizer has advanced an anti-CSF-1 antibody into Phase I safety testing in RA 25 . Completion of this trial, anticipated in 2009, might provide the first human bone biomarker data for CSF-1 FMS inhibition. Preclinical studies suggest that FMS inhibitors may provide oral alternatives to zoledronate, currently, the first-line therapy for the prevention of skeletal events in cancer patients, and to the RANK ligand...

Key advances in preclinical validation

A number of studies have demonstrated that antagonism of CCR2 and or MCP-1 reduces disease scores in pre-clinical models of arthritis 1,3 . Recently, the first reports of the actions of small molecule antagonists in both collagen-induced arthritis (CIA) and adjuvant arthritis models have appeared 15,16 , and they confirm the earlier findings blockade of CCR2 reduced disease score. In stark contrast with the aforementioned studies, the first report of the effects of genetic deletion of CCR2 in mouse CIA showed that CCR2_ _ mice exhibited exacerbated disease 17 . Moreover, CCR2_ _ mice developed chronic polyarthritis after infection with Mycobacterium avium, whereas wild-type (WT) littermates did not 18 . Finally, an independent study documented that administration of an anti-CCR2 antibody worsened CIA when administered therapeutically (after disease initiation) but blunted disease if administered during disease initiation 19 . It is unclear how to reconcile the conflicting data at this...

Potential concerns with targeting CCR2

Recently, some authors have raised concerns that suppressed trafficking of CCR2+ T-regulatory cells might increase inflammation and exacerbate autoimmune responses. For example, the numbers of murine CCR2+ CD25+ regulatory T-cells increase during the progression phase of CIA, and the authors postulate the blockade of these cells may by responsible for the exaggerated immune response observed when an anti-CCR2 antibody was administered after disease initiation 19,55 . Of note, human regulatory T-cells (ThIL-10high) express CCR2 and are more responsive to MCP-1 than to other chemokines 56 . Finally, MK-0812, the aforementioned small molecule CCR2 antagonist, increased C-reactive protein in rheumatoid arthritis patients and provided less clinical benefit than placebo, suggesting that the compound might exhibit pro-inflammatory activity 48 .

Aryl and heteroarylamides

From a simple arylamide high-throughput screening (HTS) hit (IC50 400 nM), a series of 2-cyano-5-carboxamide inhibitors were identified with FMS kinase IC50s of about 5 and 100 nM in a cellular assay of CSF-1-stimulated bone marrow-derived macrophage (BMDM) proliferation 47-49 . A co-crystal structure of an early analog (1) was obtained with FMS. Interaction occurs in the hinge region of the adenosine triphosphate (ATP) pocket and involves a hydrogen bond between the arylamide carbonyl and the backbone NH of Cys666. The ring oxygen of the furan is not involved in direct binding to a specific FMS residue instead, it shares an intramolecular hydrogen bond with the amide NH, thereby stabilizing a flat conformation of the arylamide core. The methylpiperidine occupies the ATP sugar pocket and the hydroxymethyl extends away from this region, making a hydrogen bond with the phenol of Tyr665 50 . In a 20-kinase selectivity panel, 1 inhibited only TrkA greater than 50 at 1 mM. Further...

Quinazolines quinolines and quinolones

A quinoline urea derivative, Ki20227 (6) with kinase IC50 of 2 nM as well as modest selectivity versus VEGFR2 and c-Kit (IC50s 12 and 451 nM respectively), has been shown to inhibit CSF-1-dependent growth of M-NFS-60 cells in vitro 24,61 . Compound 6 also inhibits osteoclast development both in vitro and in vivo and suppresses metastatic tumor-induced osteolysis. Compound 6 inhibited CSF-1-dependent LPS-induced TNF production in BMDM in vitro 26 . Administration of 0.02 6 in food suppressed joint inflammatory cell infiltration as measured by F4 80 immunostaining and improved the clinical score from day 8 to 30 in a mouse collagen-induced arthritis model (p 0.0032) 21 .

Glycinamidelinked antagonists

CCR2 antagonists with activity in murine models are rare. Compound 16 was described as an orally bioavailable murine CCR2 antagonist (mouse CCR2 binding and chemotaxis IC50 values 10 nM) with good selectivity versus other murine chemokine family members, and hence it was taken into several classical in vivo efficacy models 15,84 . When dosed in the rat adjuvant arthritis model (100 mpk p.o. b.i.d.), compound 16 displayed 82 inhibition of joint inflammation as well as 64 inhibition of bone resorption. Compound 16 was also shown to be efficacious in several murine models thioglycolate-induced peritonitis, delayed-type hypersensitivity reaction, diet-induced obesity, and EAE 15,27 . Recently, salt forms of a single compound, 17, from the same genus were the subject of a separate invention 85 .

Unsaturated heterocycles

Several patents claiming aryl sulfonamides have recently appeared 117-121 . In the first, compound 43 was described to be effective in the rat collagen-induced arthritis model when dosed at 100mpk (s.c., q.d., from day 9-17) 117 . This patent also reported that compound 44 significantly inhibited the number of monocytes recruited following thioglycolate injection in a rat peritonitis model. Two other patent applications describe sulfonamides 45 120 and 46 121 as CCR2 antagonists.

Dual 5LOCOX inhibitors

Licofelone (ML-3000, 4) is the most clinically advanced dual 5-LO COX inhibitor 59,60 . Licofelone was shown to be a balanced inhibitor of both 5-LO and COX when assayed for calcium ionophore stimulated eicosanoid formation in cell based assays, including polymorphonuclear leukocytes (PMNL). Licofelone selectively inhibits COX-1 over COX-2 (ratio IC50 COX-1 IC50 COX-2 0.43) in stimulated bovine aortic coronary endothelial cells 61 . Although licofelone exhibited inhibition of TxB2 production in calcium ionophore stimulated human whole blood (indicative of COX inhibition), LTC4 levels were unaffected 62 . Licofelone inhibits IL-1 b stimulated matrix metalloprotease-13 production and expression in human osteoarthritis chondrocytes, suggesting another mechanism unrelated to the inhibition of 5-LO COX by which it may modulate the inflammatory process 63 . Licofelone (200 mg bid) demonstrated clinical efficacy similar to naproxen (500 mg bid, 12 weeks or 52 weeks) or the COX-2 selective...

Infectious Lung Disorders

Bacterial infection accounts for 30 to 50 percent of pneumonia cases in adults. Streptococcus pneumoniae (pneumococcus) is the most common bacterium involved, although many other microorganisms can cause bacterial pneumonia. The bacteria that cause pneumonia can spread throughout the body once they have entered the lungs. This can result in infection in the bloodstream (bacteremia or sepsis), the covering of the brain (meningitis), the lining of the heart (endocarditis), or the fluid in the joints (septic arthritis). Symptoms of pneumococcal pneumonia can appear either suddenly or gradually and include fever, pain on the affected side, shortness of breath, and a cough that produces mucus (the mucus is often blood-streaked).

Nonpeptidic Hydroxamic Acid MMP Inhibitors

H-bonding interactions with the enzyme. However, the group at Roche found that the P2' amino acid could be replaced by a nitrogen heterocycle, and potent activity against the collagenases could be maintained, if a cyclic imide group was introduced at P1 (82,83). From these studies, the orally active hydantoin derivative Ro 32-3555 15 was identified as a development candidate for the treatment of arthritis (84).

Spectrum Of Disease

The clinical manifestations of brucellosis vary greatly, ranging from asymptomatic infection to serious, debilitating disease. For the most part, brucellosis is a systemic infection that can involve any organ of the body. Symplon ire nonspecific and include fever, chills, weight loss, sweats, headache, muscle aches, fatigue, and depression. Lymphadenopathy and splenomegaly are common physical findings, After an incubation period of about 2 to 3 weeks, the onset of disease is commonly insidious. Complications can occur, such as arthritis, Spondylitis (inflammation of the spinal cord), and ifcldocarditis.

Disorders of the Small Intestine

Gastrointestinal symptoms of celiac disease include recurring abdominal swelling and pain fatty, yellow stools and gas. Weight loss and unexplained anemia (characterized by fatigue and weakness) often occur. Other possible symptoms include bone or joint pain, muscle cramps, tooth discoloration, tingling and numbness in the legs, mouth sores, a painful skin rash, and behavior changes (such as depression). To diagnose celiac disease, doctors perform special blood tests and use an endoscope (viewing tube) to help remove tissue samples from the small intestine for microscopic examination.

Clinical Trials Status

GSK has completed a phase II trial for dental pain (third molar tooth extraction) and two phase II trials for osteoarthritis pain with their clinical candidate GW842166. The results of these trials have not been disclosed thus far. Glenmark pharmaceutical's recent press release indicated successful completion of a phase I trial in Europe for their clinical candidate GRC10693 for neuropathic pain, osteoarthritis, and inflammatory pain disorders 68 . The structure of this candidate has not been disclosed.

Matrix Metalloproteinase Inhibitors for Treatment of Cancer

Overview of the MMPs Several excellent reviews on the design of MMP inhibitors have appeared (1-16). The MMPs are a family of zinc-containing, calcium-dependent enzymes involved in tissue remodelling and degradation of the ECM proteins, angiogenesis, and cell motility (17-20). Currently, 20 human MMPs are known (Table 1). The MMPs belong to the matrixin family, and they may be subdivided into five classes according to their substrate specificity, primary structures, and their cellular localization. MMP-23 is the most recently discovered MMP to be cloned and characterized (21). The enzymes are expressed as inactive zymogens which are activated by serine proteases, e.g., furin and plasmin, and other MMPs. The zymogens are excreted by a variety of connective tissue and pro-inflammatory cells, including fibroblasts, osteoblasts, endothelial cells, macrophages, neutrophils, and lymphocytes. The MMPs generally consist of four distinct domains an N-terminal pro-domain, a catalytic domain, a...

Therapeutic significance

Numerous studies have demonstrated that FTY720 synergizes with classical immunosuppressants (e.g. cyclosporine A, FK506, RAD001, steroids) in rodent and non-human primate models of solid organ and islet transplantation 24,25,37,42 . The most profound activity of FTY720 monotherapy has been seen in experimental autoimmune encephalomyelitis (EAE) 24,31,43 . Efficacy has also been reported in models of systemic lupus erythematosus, graft versus host disease, type-1 diabetic mice, adjuvant- and collagen-induced arthritis, experimental autoimmune myocarditis, colitis, experimental autoimmune thyroiditis and uveoretinitis 24,25,44-51 .

Further Clinical Opportunities For Hdac Inhibitors

Another therapeutic strategy uses HDAC inhibitors to modulate the expression of genes involved in the pathogenesis of rheumatoid arthritis 74 . The current treatment options, which suppress immune responses or ameliorate inflammation, do not halt the destructive process. It was found that the HDAC inhibitors phenylbutyrate and Trichostatin A causing histone hyperacetylation to modulate multiple gene expression and inhibited the expression of TNF-a in an animal model of rheumatoid arthritis.

Inhibitors Of p38 Pathway

A large number of p38 inhibitors have been discovered in the past 15 years. Many excellent reviews cover this topic well 58-60 and hence will not be discussed here. Compounds that specifically inhibit MKK3 and or 6 or upstream kinases at the MKKK level in the p38 pathway have not been reported to date, although a number of patents on kinase inhibitors disclose compounds that inhibit MKK3, 6 along with a list of other kinases. PH-089 is a potent, selective and ATP-competitive MK2 (MAPKAPK2) inhibitor with IC50 126 nM 61 . The compound inhibited TNFa production in human peripheral blood monocytes (PBMC) with IC50 1.08 mM. PH-089 at an oral dose of 60 mg kg, b.i.d., inhibited paw swelling by 55 in a streptococcal cell wall-induced arthritis model in rats. This result is in line with the data from the MK2 knock-out mice which were resistant to collagen-induced arthritis 62 . Compound 20 has also been claimed in a patent application as a MK2 inhibitor with no activity information 63 ....

Epidemiology pathogenesis and spectrum of disease

Whipple's disease, found primarily in middle-age men, is characterized by the presence of PAS-staining macrophages (indicating mucopolysaccharide or glycoprotein) in almost every organ system. The bacillus is seen in macrophages and affected tissues but it has never been cultured. Patients develop diarrhea, weight loss, arthralgia, lymphadenopathy, hyperpigmentation, often a long history of joint pain, and a distended and tender abdomen. Neurologic and sensory changes often occur. Although less common than intestinal or articular involvement, cardiac manifestations can also occur, including endocarditis.25 It has been suggested that a cellular immune defect is involved in pathogenesis of this disease.

Control Of Mmp Activity

Transcriptional regulation - HFC and HFS are transcriptionally regulated by tumor promoters such as phorbol esters, mediators of inflammation such as IL-1, growth factors, and oncogenes (14). The time-dependant upregulation of HFS and HFC by IL-1, and the presence of elevated IL-1 levels in inflammatory diseases such as rheumatoid arthritis, has led to the strategy of attempting to prevent inflammation-related tissue damage via IL-1 antagonism (31). HNC is not transcriptionally active in mature neutrophils (10).

Obesity Therapeutics Prospects and Perspectives

Obesity is often mischaracterized as a cosmetic, or life style issue when in fact it is a devastating disease with tremendous health and financial consequences. In the US alone, it has been estimated that there are greater than 300,000 deaths per year (2). This distressing effect on life expectancy is largely related directly to the life threatening co-morbidities of obesity such as non-insulin-dependent diabetes, hypertension, coronary artery disease, and some forms of cancer (3). The less lethal comorbidities associated with obesity include gallstones, osteoarthritis, degenerative arthritis, and apnea. The financial consequences of obesity can be measured in multiple ways as a total cost to society (direct and indirect), estimated percent of total medical cost, and direct value of obesity related medications (4-6). Whichever parameter is chosen to measure the financial impact of obesity, the cost is highly significant to our society.

Disorders of the Soft Tissues

A bursa is a fluid-filled sac between a bone and a tendon or muscle that allows the tendon to slide smoothly over the bone. Bursitis occurs when repeated stress and overuse cause the bursa to become inflamed and swollen with excess fluid. Bursitis also can result from injury, rheumatoid arthritis, gout, or infection. Bursitis most often occurs in the shoulder but also can affect the hip, knee, elbow, Achilles tendon, or ankle. Often the nearby tendon also becomes swollen. Bursitis usually can be treated with rest, ice, and nonsteroidal anti-inflammatory medication. Occasionally it is necessary for a doctor to withdraw excess fluid from the bursa using a needle and syringe. If an infection is present, the doctor will prescribe antibiotics. If there is no infection, the doctor may inject a

Summary And Conclusions

The relationships between required nutrients, as well as the diverse array of other substances in the diet, and angiogenesis is a relatively new area of scientific investigation that is undergoing rapid expansion. The critical roles of angiogenesis in many disease processes, including wound healing, arthritis, vasculatitis, retinopathy, tissue responses to ischemia, and cancer, are beginning to be appreciated (2). Many of these disease processes in experimental animals and humans are also profoundly modulated by diet and nutrition (6,9,10). Future studies will undoubtedly reveal many steps in the angiogenic process modulated by substances contained in foods. The additional knowledge generated will be relevant to optimizing experimental models employed by many angiogenesis investigators. Furthermore, the incorporation of dietary assessment and controlled nutritional intake into clinical trials of angiogenesis modulators will reduce heterogeneity, and improve the power and sensitivity...

Disorders of the Joints

Osteoarthritis Arthritis is a general term that refers to inflammation of one or more joints. There are more than 100 arthritic disorders. Osteoarthritis, which most people refer to as simply arthritis, is a chronic joint disease that affects many middle-aged and older Americans. Osteoarthritis that has no obvious cause is called primary arthritis. Osteoarthritis that results from damage to the cartilage that covers the ends of the bones in a joint is called secondary arthritis. Injury and obesity are two factors that may be involved in the development of osteoarthritis. Heredity may also be a factor. The symptoms of osteoarthritis include pain, tenderness, swelling, redness, and loss of motion or strength in the affected joint or joints. The pain tends to worsen toward the end of the day. In some people the joint may make cracking sounds when it is in motion. In osteoarthritis, joint cartilage gradually wears away, allowing adjoining bones to rub against each other. Painful...

Structure And Function Of Il1

IL-1 has a broad spectrum of biological activities (29). It regulates lymphocyte development, activation and proliferation, and induces lymphokine expression (36). The proinflammatory effects of IL-1 include the production of prostaglandins, neutral proteases and IL-6 by fibroblasts, synovial cells, chondrocytes, endothelial cells, hepatocytes and osteoclasts (37). IL-1 also regulates body temperature and affects the central nervous system (38). In experimental models, IL-1 administered into the joint space elicits many characteristics of antigen-induced arthritis (39). The profound effects of IL-1 on connective tissues, neutrophils and endothelial cells contribute to disease states. For example, IL-1 is found in the joint fluid of arthritic patients at elevated levels (53-55). Activation of osteoclasts and osteoblasts by IL-1 is important for bone remodeling in joint diseases. IL-1 potentiates neutrophil infiltration, degranulation and adhesion to endothelium (56) resulting in...

Fibroblast Growth Factor Receptor Tyrosine Kinase Inhibitors

In normal tissues, fibroblast growth factors (FGFs) are mitogenic toward a variety of cells, including mesenchymal, neuronal and epithelial cells. This family of growth factors is involved in regulation of cell growth and differentiation, embryogenesis and angiogenesis. Overexpression of FGFs and or the FGFRs has been linked to several pathologies, including tumorigenesis, psoriasis, rheumatoid arthritis and diabetic retinopathy (62). The interest in FGFR has been stimulated primarily by its involvement in angiogenesis and the necessity of this process to tumor growth and metastasis. Elucidation of the mechanism through which FGFs and FGFRs function in the angiogenic process points more toward their involvement with the maintenance of tumor angiogenesis than its initiation (VEGF is thought to be responsible for the initiation of tumor angiogenesis) (63). Unlike the EGFR and PDGFR inhibitors, inhibitors of fibroblast growth factor receptor tyrosine kinase (FGFR) act on noncancerous...

Agents Exhibiting Il1 Modulation

Inhibitors of Synthesis or Release - The disease modifying antirheumatic drugs (DMARDs) chloroquine (1), auranofin (2), sodium aurothiomalate (3) and dexamethasone (4), used clinically for the treatment of chronic rheumatoid conditions such as rheumatoid arthritis, have been reported to inhibit IL-1 synthesis (60). While both gold drugs 2 and 3 inhibited mitogen-induced IL-1 release from peripheral blood mononuclear cells (PBMC), only 2 inhibited both spontaneous release and LPS induced release (61). The mechanism of action of 4 was recently shown to be at two levels jn vitro transcription assays with isolated nuclei from glucocorticoid treated cells show inhibition of IL-1 gene transcription, and kinetic studies involving pulse-labeling of mRNAs demonstrate a selective destabilization of the IL-ip mRNA (62). Tenidap (5, CP-66,248) is an antiarthritic drug in clinical phase III trials, and has shown efficacy both in patients with osteo- and rheumatoid arthritis (RA) (63). Clinical...

Inhibitors of p38a MAP Kinase

Introduction - p38 MAP kinases (Mitogen Activated Protein kinases) are intracellular soluble serine threonine kinases. There are four isoforms in the p38 MAP kinase family p38a, p38p, p38y and p388(1-3). p38a and p38p are expressed in all tissues, p38y is expressed primarily in skeletal tissue and p388 is expressed mainly in the lung, kidney, testis, pancreas, and small intestine. These enzymes show high amino acid sequence conservation, particularly in the ATP binding pocket. All p38 MAP kinases have a Thr-Gly-Tyr dual phosphorylation motif and dual phosphorylation is essential for activation of these enzymes. p38a is phosphorylated on Thr-180 and Tyr-182 was thought to be the primary and only mode of p38a activation. However, a recent report has detailed a new mechanism for the activation of p38a that involves autophosphorylation due to its binding to TAB1 (transforming growth factor-p-activated protein kinase-1-binding protein 1) (4). All MAP kinases exhibit exquisite substrate...

Targeting Nonhepatic Hmgcoa Reductase

Diminish, both through empirical observation and directed trials. This factor may already account for the variability in the results from some clinical trials. Taken together, these previous data suggest that there may be further opportunity for chemistry optimisation of statin class drugs achieving higher systemic exposure, to exploit these potential novel mechanisms, assuming that the mechanism behind muscle toxicity can be understood and avoided. Alternatively, there exists the possibility of delivering statins at high relative concentrations to local sites and optimising the structure of the statin to ensure it is rapidly metabolised to an inactive form, either on exposure to the systemic circulation, or through efficient clearance on first pass metabolism, i.e., a 'soft statin' approach. Clinical conditions amenable to this strategy include asthma, allergic rhinitis or dermatitis, psoriasis, or even arthritis.

Obesity And Abdominal Adiposity

Dyslipidemia, obstructive sleep apnea, liver disease, and degenerative joint disease. A subset of obese patients demonstrate abdominal obesity or adiposity which is defined by increasing waist circumference, sagittal abdominal diameter, and waist-to-hip ratio. Waist circumference and sagittal abdominal diameter have been shown to correlate best with intra-abdominal adiposity which is a risk factor for cardiovascular disease as well as for dyslipidemia and diabetes18. The definition for abdominal adiposity varies between different ethnic populations as well as within the current literature. A recent study revealed that 36.9 of men and 55.1 of women in the US met the definition of abdominal adiposity based on high-risk waist circumference (waist circumference of greater than 102 cm in men and greater than 88 cm in women)19.

Pharmacodynamic Dose Optimization

Dose optimization interventions are likely to be one of the most common interventions from an ASP. Although formerly viewed as a means to efficiently trim excess drug exposure secondary to renal dysfunction, the modern application of pharmacodynamic principles is important in order to maximize drug exposure for organisms with elevated MICs, patients with excess body mass indices, and for closed-space or otherwise difficult-to-penetrate sites of infection (e.g., meningitis, endocarditis, pneumonia, bone and joint infections). A recent paper provides a more in-depth review of the subject and serves as a primer for all ASPs incorporating optimal dosing strategies (100). Although we approached our program with the thought that may patients would receive downward dose adjustments for renal impairment, what we found was a significant proportion of patients required increased drug exposure (20,21). Other examples of pharmacodynamic dose-optimization include regimens intended to treat higher...

Searching for Alzheimers Disease Therapies In Your Medicine Cabinet The Epidemiological and Mechanistic Case For NSAIDs

Despite this bleak clinical picture, an intriguing story has emerged in recent years from epidemiological studies asking whether the use of any currently marketed drugs is associated with a decreased risk of AD. Two classes of drugs have consistently emerged in the affirmative for this question. The first are the nonsteroidal anti-inflammatory drugs (NSAIDs), commonly used either acutely in the treatment of mild to moderate pain, swelling, and fever, or more chronically in the treatment of rheumatoid arthritis. The second is a class of popular cholesterol-lowering drugs known collectively as statins, used as a primary preventative to block the development of atherosclerosis. This epidemiological record has spawned a growing literature that seeks to explore the mechanisms by which both of these classes of drugs might have their purported protective effects in AD. inflammatory response, NSAIDs would not a priori be predicted to have efficacy against this inflammatory response. This is...

Current Research Aimed At Prostanoidderived Therapeutics

A recent review has comprehensively covered PG receptor signaling in disease and the resulting therapeutic implications 84 . From the studies discussed it is postulated that selective manipulation of individual receptors may be beneficial in the treatment of acute inflammation, pain, fever, arthritis, inflammatory bowel disease, pulmonary fibrosis as well as the effects on dendritic cells, thymocyte development, development and function of mature lymphocytes and B lymphocyte class switching. Recent drug discovery studies and on-going clinical development of PGs are presented later.

Which bones am I more likely to break

Fracturing a bone in your forearm, usually near your wrist, does not cause the same problems of disability and even death that are attributed to hip fractures. However, wrist fractures can cause persistent pain, functional and nerve problems, bone deformities, and arthritis. Although a wrist fracture is less likely to cause problems with walking and being mobile, it can still restrict you from getting out of the house, especially if you need to drive. It can also prevent you from doing activities of daily living, such as bathing and meal preparation. You will likely have a cast applied to your forearm, which includes the area below the elbow down to the thumb and fingers. Typically, a simple fracture requires a cast for 4 to 6 weeks, but depending on your ability to heal, you may have a cast longer. Although my ankle fracture occurred about 5 months ago, I think it's going to take me a full year to recover. I never would have guessed that this type of fracture could take so...

Cytokine Measurements in Disease

Elevated plasma levels of IL-1 have been detected in a wide range of different conditions that are characterized by inflammation such as rheumatoid arthritis (RA), acute arthritides (D13, E2, M5), Crohns disease (S10), periodontitis (C16), sunburn (G20), burns (K34), endometriosis (F3), psoriasis (C5), gram-positive meningitis (Sll), and extended exercise in healthy volunteers (C9). In RA there is some correlation with disease activity (E2). In synovial fluid, biologically active and immunoreactive IL-1 are detectable in rheumatoid arthritis, osteoarthritis, and other arthritides, and inhibitory activity in biological assays is present in many cases (F22, H30, N13, S43, W30). In a study of synovial fluid from various arthritides, 49 of 111 fluids contained immunoreactive IL-1 of these 74 were from RA and 15 from seronegative arthritides, whereas 11 were from patients with noninflammatory arthritis (W19). Syntheses of IL-ip mRNA (B66) and the IL-1 (3 molecule have been demonstrated in...

Syk kinase inhibitors which have progressed to clinical studies

An orally bioavailable prodrug of 4 is currently in clinical trials for treatment of RA and immune thrombocytopenia purpura 33,34,66 . This compound potently inhibited all Syk-dependent cell-based assays, including Fc receptor signaling in human macrophages, neutrophils, mast cells and B-cell receptor signaling in human B cells. Selectivity was demonstrated by the examination of inhibition of phosphorylation in cells, and with a panel of off-target Syk-independent cell-based assays. Inhibition of Flt3, Jak and Lck, was also observed, which for inflammatory processes might be considered to be favorable 34 . Animal models were conducted that could be directly correlated to IC-mediated inflammatory processes proven to be dependent on activating Fcg receptors 33-35 . Such models included the passive Arthus reaction and passive anticollagen type II antibody-induced arthritis (CAIA) models 33-35 . Based on the compound's biological potency, selectivity, PK characteristics, safety and...

Measuring the Angiogenic Process

The quality and distribution rather than the quantity of blood vessels appear to be important in maintaining the healthy joint. The questions here, rather than being what makes blood vessels grow, may be more appropriately put as what makes them grow in a particular direction, what makes them branch and anastomose, and what determines the particular distribution of arterioles, capillaries, and venules. In addition, the growth of fine unmyelinated sensory nerves along newly formed blood vessels in tissues that are normally avascular may contribute to the chronic pain of some inflammatory and angiogenic diseases such as arthritis and spondylosis 6, 17 .

Current Status Of Our Understanding Of Human Diseases At The Molecular Level

What about more complex diseases such as diabetes, heart disease, arthritis, cancer or schizophrenia Building up the etiology step by step by discovering genetic variants, and environmental factors is a monumental task. By identifying the key pathways nodes involved, one can pinpoint the most effective end points for intervention. New comprehensive, multi-parallel approaches are needed to identify such pathway nodes.

New Methods To Identify Genes And Pathways Activated In Complex Multifactorial Diseases

Another example is the use of genomic approaches to understand a complex multi-factorial disease such as osteoarthritis (OA). OA is a very prevalent joint disease and most individuals over age 60 have radiographic or histological signs of OA 36,37 . Current therapeutic approaches are directed toward symptomatic relief because pharmacologic interventions that prevent disease progression are not available. Many patients thus progress to advanced disease where total joint replacement surgery is indicated. The major pathological change and source of subjective symptoms and joint dysfunction is the progressive loss of articular cartilage.

Are there any medications that I should adjust or stop taking while Im being treated for osteoporosis

Systemic lupus erythematosis (SLE or lupus for short) and other inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel diseases, and asthma, are often treated with steroids for long periods of time, but it does not take long for steroids to weaken bones. In fact, significant bone loss can occur with > 7.5mg daily in as little as 3 months. Courses of treatment for longer than 6 months give you a 50 chance of developing osteoporosis. So, in terms of your bones, it is critical to find ways to reduce your dosage of steroids or to begin medications such as a bisphosphonate and, if appropriate, estrogen therapies, that will help prevent further bone loss. One of the alternative medications to steroids for rheumatoid arthritis and other autoimmune disorders is methotrexate, traditionally used for the treatment of cancers. Unfortunately, methotrexate can cause bone loss as well. Knee joints wear out as a result of aging and osteoarthritis. Knee joints wear out as a result...

Therapy And Prophylaxis

Due to difficulty in propagating the virus in vitro, there is no vaccine. During local epidemics, transfusion of packed erythrocytes or the administration of normal human immunoglobulin may afford some protection to individuals at risk of aplastic crisis. There is no indication for termination of pregnancy if maternal infection occurs, since no abnormalities have been noted in babies born to mothers whose pregnancy has been complicated by B19 infection. The symptoms of B19 infection may be treated as appropriate erythrocyte transfusion for aplastic crisis, calomine lotion for pruritic rash, anti-inflammatory agents for arthritis. Intravenous immunoglobulin is effective in controlling chronic infection in the immunocompromised.

Historical Perspective of Epidemiological Studies of Weight

The relationships between excess body weight and mortality from all causes and from cardiovascular disease have been well-established in epidemiological studies (20-24). Excess weight is also known to be associated with an increased risk of morbidity, including cardiovascular diseases, type 2 diabetes mellitus, hypertension, dyslipidemia, glucose intolerance, and osteoarthritis (1,2).

Therapeutic Targeting of Angiogenesis

Angiogenesis inhibition has been explored for its therapeutic potential in a variety of clinical areas. Initially driven by the hope that blocking new vessel growth will improve prognosis in solid tumors, drugs developed primarily for the oncology field have been applied to conditions as diverse as arthritis, psoriasis, and macular degeneration 152-154 . A potential drawback of the use of agents which inhibit all angiogenesis in nonmalignant disease is the likelihood that they would also impair physiological angiogenesis. The use of broad-spectrum angiogenesis inhibitors such as thalidomide in fertile women would seem inappropriate. However, concerns about teratogenicity need not absolutely deny access to such drugs. Concern about impaired wound healing from chronic angiogenesis inhibition may be circumvented by targeting antiangiogenic treatments to phases of active angiogenesis during the disease, perhaps, for example, during flares of arthritis.

Clinical Presentation

Diseases due to C. difficile represent a wide spectrum. These ranges from asymptomatic cases, watery diarrhea, dysentery, PMC, complicated colitis and bacterial metastatic infections (7,8). Some degree of watery diarrhea, infrequent with blood or mucus, develops in most patients. The extent of other abdominal complaints or systemic symptoms varies from mild to severe. The disease may be fatal. Abdominal pain, cramps, lower quadrant tenderness, fever, and leukocytosis are common. Other findings include nausea, malaise, anorexia, hypoalbumi-nemia, anasarca, electrolyte disturbances, occult colonic bleeding, and dehydration. Extraintestinal manifestations are rare and include bacteremia, generally polymicrobial, splenic abscess, osteomyelitis, and reactive arthritis or tenosynovitis.

Post Genomic View of Aging Definitions Theories and Observations

Rather than individual chronological age, aging may be more closely related to epigenetic and environmental factors, including stress and the absence of disease. The aging human populations may develop different physiological or anatomical defects and may die from different age-dependent diseases. Diseases such as Alzheimer disease, cardiovascular disease, osteoporosis, cancer, diabetes, and arthritis, affect too many older men and women, and seriously compromises the quality of their lives.

Whats the likelihood that I will die from osteoporosis

Is that related to my osteoporosis What can I do for the joint pain Exercise seems to make the joint pain worse. Joint pain usually results from wear and tear on the cartilage, causing osteoarthritis to develop. This type of arthritis causes inflammation and pain in the joints. The cartilage usually provides a buffer between the bones in your joints. When it is injured from years of weight-bearing and activity, you can develop joint pain and osteoarthritis. While you might think that exercising would cause more discomfort, injure the joint, and increase joint degeneration, it does not. It is more damaging to your health to carry around extra weight and to develop weak muscles and bones. In a recent small study, regular moderate exercise (aerobic and weight-bearing activities for one hour three times per week) was associated with improved physical activity and knee joint function as well as improved strength of knee cartilage. It's important to exercise even when...

Dont want steroids Are other treatments available for MS attacks

Traditionally, the management of MS centered on the use of extended periods of physical (and mental) rest, as it did for patients with tuberculosis or rheumatoid arthritis. Today, relapse management in MS seems to revolve around the use of steroids. ACTH was approved for the treatment of attacks of MS by the FDA in 1978 and remains the only drug approved for treatment of MS attacks. The IV form of ACTH is in very short supply, but the intramuscular form (ACTHAR Gel) is again in production and can be obtained with a prescription. Rheumatoid arthritis a common inflammatory joint disease caused by an autoimmune response.

Are there treatments to prevent attacks and lessen risk of disability

Ized by 6 weeks of treatment and the accompanying reduction of sustained disability, the drug has been withdrawn from the market. The withdrawal was necessary because, unfortunately, 2 of the 589 patients who had received Avonex and Tysabri (one for 23 and the other for 37 months) developed PML, a fatal opportunistic viral disease of the brain. In addition, a patient with Crohn's disease who had received multiple drug therapies also developed this disease. Of the approximately 3,000 patients with MS, Crohn's disease, or rheumatoid arthritis, the only patients who developed PML were those two MS patients on combined Tysabri and Avonex therapy and the Crohn's disease patient who had received multiple immuno-suppressants as well as Tysabri. The drug has been withdrawn from the market pending a full review of the relevant facts.

Congress Needs to Step Back from the FDA Especially Where Science Is Concerned

As illustrated by the Ketek fiasco, the FDA must be protected from inappropriate intrusion by congress. Politics has no role to play in the practical and scientific establishment of clinical trial designs. The move by congress to extensively investigate the FDA's handling of antimicrobial clinical trial designs was an unneeded distraction to an already overburdened agency at a critical juncture. FDA staffers were spending hours providing materials for a possible investigation which, in fact, never materialized. It also led to the unnecessary transfer of a very talented and dedicated director of antimicrobial products and ophthalmology that has further eroded FDA leadership in this area. In my view, if the congress has serious scientific questions regarding FDA's conduct, the matter should be turned over to the National Academy of Science that exists for the very purpose of providing neutral scientific assessments for congress.

Of the available lupus-prone strains, MRL Mp and their congenic MRL Mp-lpr lpr strains develop the most systemic and severe form of autoimmunity, involving multiple autoantibody specificities, such as anti-dsDNA, ribo-nucleoprotein (including small nuclear ribonucleoproteins snRNPs , Ro, La, Su), ribosomal, and erythrocyte, as well as rheumatoid factor and cryoglobulins. End-organ disease includes not only varying and severe forms of glomerulonephritis, but also sialoadenitis in about 90-95 and inflammatory arthritis in about 75 , as well as less-often described but often seen inflammatory lesions of the liver, eyes, blood vessels, reproductive organs, and nervous system (7,101,103,104).

Experimentally Induced Models

The aliphatic hydrocarbon pristane (2,6,10,14-tetramethyl-pentadecane) has long been known to induce plasmacytomas (196-199) and arthritis (200-204) in susceptible BALB c mice. Relatively recently, it was found to induce, in several strains, many different serological autoimmune phenomena, including anti-DNA and antiribonucleoprotein antibodies and glomerulonephritis (205208), through mechanisms dependent on IFN-y (209), IL-6 (210), and CD95-CD95L interactions (211). In some strains, antiribosomal P antibodies are seen as well (212). Because plasmacytoma induction by pristane exhibits both strain and housing dependence, it remains unclear whether this model will be widely useful in the study of murine lupus (213,214).

Obesity and joint structure

Although OA manifests as joint changes that primarily include progressive cartilage loss and bony abnormalities such as subchondral sclerosis, osteophytes, and bone cysts, it is unclear how obesity influences joint morphology. To date, the majority of studies have measured the BMI (kg m2) as an indicator of obesity, and only relatively recently have parameters of body composition, such as fat distribution and lean body mass, been examined in the context of joint disease. Nevertheless, there still remains a paucity of data examining the association between joint structure and increased body mass. This lack of specific data may be partly attributable to the difficulty in obtaining reliable, valid, and sensitive measures of cartilage, bone, and body composition properties non-invasively in human subjects. However, magnetic resonance imaging (MRI) and dual-energy X-ray absorptiometry (DEXA) are becoming widely accepted as noninvasive, reliable, valid, and sensitive measures of cartilage...

Association Between Obesity and Knee OA

Given that the knee is composed of distinct compartments, the association between obesity and knee OA may differ between the different knee compartments. Of the few studies that have examined the association between obesity and compartment OA, one cross-sectional study of middle-aged women demonstrated that obesity was an important risk factor for both medial tibiofemoral and patellofemoral joint disease (35). Another study demonstrated an association between obesity and tibiofemoral OA, but failed to show a relationship at the patellofemoral joint (40). These contrasting results highlight the need to clarify the association between obesity and OA at the different compartments in the knee complex. Nevertheless, the association between obesity and knee OA is unequivocal.

Cell Therapy From The Laboratory To The Stroke Patient

The feasibility and safety of human BMSCs have been tested and confirmed in patients with degenerative arthritis for resurfacing of joint surfaces by direct injection into the joints (53). In breast-cancer patients infused intravenously with culture-expanded autologous BMSCs (54), and in patients with lysosomal and peroxisomal storage diseases treated with allogeneic BMSCs (55), no apparent adverse effects were evident. BMSC systemic injection has also been employed to treat patients with severe osteogenesis imperfecta to correct genetic defects (56). The robust therapeutic benefit of BMSCs in the treatment of experimental neural stroke and the apparent safe and broad application of BMSC therapy to the treatment of diseases provide a compelling reason to investigate the potential of MSC treatment of stroke. Moreover, the use of patients' own MSCs should circumvent any potential problems of host immunity and graft-versus-host disease. The easily accessible vascular route, as opposed to...

Immunoregulation In The Ocular Surface System

Endogenous, systemic factors also may adversely influence the lacrimal glands' ability to generate tolerogenic DCs and regulatory T lymphocytes. Prolactin is a paracrine mediator in the local milieu that seems to especially warrant scrutiny. It has been implicated in a number of immunomodulatory roles in addition to support of mammary epithelial pIgR expression and IgA+ plasma cell accumulation. Treatment with bromocriptine, which suppresses pituitary prolactin secretion, suppresses contact sensitivity, antibody formation, adjuvant arthritis, experimental allergic encephalitis (167) and induction of tumoricidal macrophages (168).

Conclusions

You would think that once we, as a global society, realized the truth of this incontrovertible scientific conclusion, we would find a way to make sure that we fulfilled our responsibilities to provide for this clear medical need. But nothing is logical and action does not necessarily follow from truth. The forces that conspire against the discovery, development and marketing of new antibiotics are formidable. First, those that seem the easiest to control, our own regulatory agencies, continue to develop policies that will only further discourage the development of new antibiotics. This by itself has far-reaching consequences that most don't realize. If the regulatory environment is such that development becomes expensive or simply infeasible, as is becoming the case for antibiotics in the US and even, though to a lesser extent, in Europe, companies give up. Of course, companies give up for lots of other reasons as well. The science of discovery is getting harder and harder. The market...

Conclusions and future challenges

Despite over 20 years of research, much about the regulation and function of L-selectin remains unknown. For example, while many different ligands that can be recognized by L-selectin have been described, definitive evidence demonstrating any of these molecules to be the physiological ligand for L-selectin is lacking. Furthermore, the PSGL-1-independent L-selectin ligands expressed by leukocytes remain to be identified. Important to L-selectin function is the generation of transmembrane signals through L-selectin following ligation. These signals, described following binding of ligands and L-selectin-specific mAbs, result in increased leukocyte effector functions such as enhancement in leukocyte binding activity and subsequent chemotaxis. However, it is unclear how such a short cytoplasmic tail, lacking known binding domains for signaling molecules, mediates such a variety of functions. Much of the differences observed in the migration of lymphocyte subsets can be explained by...

Clinical Clues to Diagnosis of Anaerobic Infections

Periodontitis or periopical abscess and lung abscess can be a clue to underlying bronchogenic malignancy. Malignant disease can be first detected because of an anaerobic infection. Malignancy or other process in the colon can induce sepsis with Clostridium spp. (especially Clostridium septicum) (29) or arthritis caused by Eubacterium lentum (30) or emerge first as abdominal wall myonecrosis (31). Capnocytophaga which is member of the oral microflora can cause sepsis in patients with leukemia (32). 30. Severijnen AJ, van Kleef R, Hazenberg MP, van de Merwe JP.

Irreversible inhibitors

Bmx Inhibitors

A diaminopyrimidine scaffold has also been employed to present an electrophile for attack by Cys481 44 . Compound 3 has an IC50 < 10 nM against Btk and inhibits Itk, Bmx, EGFR, and JAK3 with similar potency. Mass spectrometry confirmed that 3 covalently modifies Btk, Tec, and JAK3. Compund 3 inhibited BCR-induced PLCg2 phosphorylation (IC50 10 nM) and human primary B-cell proliferation (IC50 10 nM), and was orally efficacious in rodent arthritis models at 30 mg kg.

Roles of Btk Syk and PI3K in Bcell biology

Btk Pi3k Syk Fcr Signaling

Btk is expressed in B-cells, monocyctes, mast cells, and osteoclasts, but not T-cells. Btk is essential for B-cell development and defects in the Btk gene lead to X-linked agammaglobulinemia (XLA) in humans, which is characterized by a lack of circulating B-cells and serum immunoglobulins 22,23 . Btk-deficient mice are resistant to the development of SLE and collagen-induced arthritis (CIA) 24 . Antigen binding to the BCR activates Src family and PI3 kinases, and Btk is recruited to the plasma

Custom joint replacement implants

Rapid Prototyping Implants

Design and fabrication of hip and knee implants are currently being investigated. The proposed concept is to custom design implants based on patient-specific CT data. Since the proposed design of the knee implants involves the use of novel contoured bone-implant interface surfaces, they must be tested on animals before any clinical studies can be conducted on humans. The veterinary school at NCSU is currently performing hip replacements on dogs on a weekly basis using standard implant components. Both a cemented and a cementless hip implant system have been developed at NCSU where the implant components come in several sizes. Currently there are no commercial knee implants available for dogs owing to the number of sizes that would be necessary to accommodate different sizes of dog knees within a breed and between different breeds. The idea of custom designing the implant components for each patient would solve this problem for dogs, and would provide a remedy for the common condition...

Nonhydroxamic Acid Nonpeptidic MMP Inhibitors

Bayer found that the known anti-inflammatory agent, fenbufen, possesses modest inhibitory activity against gelatinase-A, and has prepared more potent analogs, such as 18 (46). This compound features a carboxylic acid zinc binding group and a cyclic imide P1 substituent. A large P1' b iphenyl group ensures selectivity for the deep-pocket MMPs. A variety of nonpeptidic natural-product MMP inhibitors have been discovered by screening. These include pycnidione (19 Merck 89), futoenone derivatives (e.g., 20 OAS-1148 OsteoArthritis Sciences) (90), betulinic acid (21 Sterling Winthrop 91), gelastatins (e.g., 22 92), and tetracyclines such as aranciamycin and minocycline, for which chemical modification (e.g., 23 CMT-1) has enabled the separation of MMP activity from antibiotic activity (93,94). Two of these compounds feature a carboxylic acid that may serve as a ZBG for others, it is possible that a ring hydroxyl and or carbonyl chelates the active site zinc(II) ion. In the case of the...

Nepafenac Antiinflammatory [5255

Nepafenac, launched last year by Alcon Laboratories, is a topical ophthalmic medication indicated for the treatment of ocular pain and inflammation associated with cataract surgery. Nepafenac is a prodrug of amfenac, which is an NSAID and a potent non-selective inhibitor of COX-1 (IC50 0.25 mM)) and COX-2 (IC50 0.15 mM). Nepefenac itself exhibits only weak activity against COX-1 (IC50 64.3 mM). Amfenac (Fenazox) has been marketed in Japan since 1986 for the treatment of rheumatoid arthritis, post-surgical pain, and inflammation. With most NSAIDs that are currently being used as topical ophthalmic agents, the maximum drug concentration is achieved on the ocular surface, with progressively lower concentrations in the cornea, aqueous humor, vitreous, and retina. Ne-pafenac has been found to have a penetration coefficient that is 4 - 28 times greater than that achieved with conventional NSAIDs such as diclofenac, bromofenac, and ketorolac. In addition, the bioconversion of nepefenac to...

Lumiracoxib Antiinflammatory [4851

Pharmacokinetic profile of lumiracoxib has been extensively documented. Lumiracoxib is absorbed rapidly with an oral bioavailability of approximately 74 . A median Tmax is reached in 2h, and Cmax is proportional to dose (range of 25-800 mg). It has a relatively short plasma elimination half-life of 3-6 h and a mean plasma clearance of 8 L h following i.v. administration. The volume of distribution is also moderate at 9 L. Lumiracoxib is metabolized predominantly by CYP2C9 with oxidation of the 5-methyl group and hydroxylation of the dihalo-aromatic ring as the primary sites of biotransformation. In circulating plasma, the major metabolites 5-carboxy-lumiracoxib (10.8 ) and 4'-hydroxy-5-carboxy-lumiracoxib (8.2 ) are not pharmacologically active against either COX enzyme however, 4'-hydroxy-lumiracoxib (5.8 ) has similar potency and selectivity as the parent. Since 4'-hydroxy-lumiracoxib has comparable plasma protein binding (98-99 ), it is unlikely that this metabolite is a major...
