15525847 Late-onset systemic lupus erythematosus: a personal series of 47 patients and pooled analy 2004 Nov Systemic lupus erythematosus (SLE) is uncommon after the age of 50 years, and studies of elderly patients with SLE are scarce. We conducted the current study to analyze characteristics and outcome of patients with late-onset SLE in a French tertiary referral center, and to compare them with those of younger patients with SLE. From 1980 to 2000, 47 patients were identified as having late-onset SLE, defined as SLE diagnosed at or over the age of 50 years. These patients were compared with a group of 114 randomly selected patients aged younger than 50 years at SLE diagnosis. We compared clinical characteristics, laboratory data, therapy, and course. The female to male ratio was smaller in the late-onset SLE group (p = 0.0012). Some manifestations occurred less frequently in late-onset SLE: arthritis (p = 0.009), malar rash (p = 0.013), and nephropathy (p = 0.009). High-dose corticosteroids (p = 0.0016) and immunosuppressive drugs (p = 0.006) were less commonly used in the elderly. Deaths occurred more frequently in late-onset SLE (p = 0.019), with a 10-year survival rate of 71% versus 95% in early-onset SLE (p < 0.01). In patients with late-onset SLE, causes of death were usually unrelated to SLE. Analysis of pooled data from the literature, based on 714 old and 4700 young SLE patients, confirmed that late-onset SLE was characterized by a smaller female to male ratio (4.4:1 vs. 10.6:1; p = 3.10); a higher occurrence of serositis (36.7% vs. 28.6%; p = 7.10) and pulmonary involvement (21.2% vs. 11.3%; p = 6.10); and a lower occurrence of malar rash (31.1% vs. 62.4%; p = 10), photosensitivity (26.2% vs. 38.2%; p = 6.10), purpura/cutaneous vasculitis (13.4% vs. 25.9%; p = 9.10), alopecia/hair loss (24% vs. 44.9%; p = 3.10), Raynaud phenomenon (24.8% vs. 37.2%; p = 3.10), neuropsychiatric manifestations (15.3% vs. 20.2%; p = 0.025), lymphadenopathy (9.1% vs. 19.6%; p = 2.10), nephrotic syndrome (8.1% vs. 24.3%; p = 0.015), and nephritis (28.6% vs. 42.7%; p = 2.10). Regarding laboratory features, rheumatoid factor positivity was more frequent (32.7% vs. 20.1%; p = 3.10), whereas anti-RNP positivity (10.4% vs. 20.9%; p = 9.10), anti-Sm positivity (9.1% vs. 17.1%; p = 0.001), and a low CH50 complement fraction (45% vs. 64.9%; p = 0.002) were less frequent in old compared with young SLE patients. In conclusion, the clinical pattern of late-onset SLE is characterized by a lower disease severity. The reduced survival observed in this group seems to result mainly from the consequences of aging.
14688380 Distortion of the self-reactive IgG antibody repertoire in multiple sclerosis as a new dia 2004 Jan 1 To date, none of the myelin-associated Ag targets definitively discriminates between the immune response observed in multiple sclerosis (MS) patients and healthy subjects. However, it has been shown recently that analysis of global immune Ab profiles such as natural autoantibody reactivities can help to distinguish between normal individuals and patients suffering from various immune diseases. The aim of our study was to compare the global IgG immune response against brain self-Ags in sera from 82 MS patients and 27 healthy subjects. The analysis of the immune profiles was performed by Western blotting, and data were subjected to linear discriminant analysis. Particular patterns of IgG reactivity were found in healthy subjects, Sjögren patients, and MS patients. Moreover, this approach separated the three clinical forms of MS with a high concordance rate with the clinical data (kappa value, 77.8%). Our study suggests, for the first time, that serum IgG Ab repertoires are able to distinguish MS patients. In addition, our data suggest that patterns of IgG reactivity could model the pathological processes underlying the various forms of MS. Further characterization of such discriminant Ags could provide useful information regarding their potent role in pathogenesis or regulatory processes in MS.
12420092 Antidisialosyl antibodies in chronic idiopathic ataxic neuropathy. 2002 Nov Antidisialosyl antibodies were found in two out of 13 patients with chronic idiopathic ataxic neuropathy (CIAN) and not in 32 patients with different sensory neuropathies of known cause. This finding confirms the association of antidisialosyl antibodies and CIAN regardless of the absence of the M band. These antibodies may have pathogenic relevance; however, larger series are needed to establish their clinical significance.
16021111 Rheumatoid arthritis: a review of the cutaneous manifestations. 2005 Aug Rheumatoid arthritis is a chronic inflammatory arthritis with significant extra-articular manifestations. Of note are unique cutaneous manifestations that the dermatologist may encounter. This article will make the dermatologist more cognizant of these skin findings in patients with this systemic inflammatory disorder. It examines rheumatoid arthritis, focusing on the general nonspecific and disease-specific rheumatoid arthritic skin changes. Classic rheumatoid nodules, accelerated rheumatoid nodulosis, rheumatoid nodulosis, rheumatoid vasculitis, Felty syndrome, pyoderma gangrenosum, interstitial granulomatosus dermatitis with arthritis, palisaded neutrophilic and granulomatosis dermatitis, rheumatoid neutrophilic dermatitis, juvenile rheumatoid arthritis, and adult-onset Still disease are reviewed. Understanding the cutaneous expressions of rheumatoid arthritis may lead to early diagnosis, prompt treatment, and lower morbidity and mortality for the affected persons. Learning objective At the completion of this learning activity, participants should be able to describe rheumatoid arthritis in terms of its epidemiology, etiology, pathogenesis, and general and specific cutaneous manifestations.
16582693 Early rheumatoid arthritis. 2006 May PURPOSE OF REVIEW: This review provides novel and updated information on pathogenesis, referral, and clinical characteristics as well as therapeutic approaches in early rheumatoid arthritis. RECENT FINDINGS: Early referral is important, but new classification criteria for early rheumatoid arthritis need to be elaborated. Predictive markers for rheumatoid arthritis are still confined to autoantibodies; respective algorithms have been presented. Other biomarkers will still have to prove their usefulness. Magnetic resonance imaging and sonography do not appear to sufficiently distinguish between early rheumatoid and nonrheumatoid arthritis. Rheumatoid arthritis has become milder at presentation in recent years. In its very early stages, the cytokine profile reflects T-cell activation and switches to abundant proinflammatory cytokines thereafter. Disease-modifying antirheumatic drugs plus glucocorticoids are highly effective, as is early use of tumor necrosis factor blockers plus methotrexate. Tight control of disease activity and subsequent therapeutic adjustments are highly effective. Disease activity indices that are simple to calculate have been presented and validated. Early intensive therapy may lead to decrease in disability and cost reduction in rheumatoid arthritis. SUMMARY: Understanding of early arthritis is increasing, especially in prognostic and therapeutic respects, and new treatment strategies appear to improve the outcome in patients with early arthritis. Nevertheless, much remains to be studied to better address the issue of early rheumatoid arthritis.
16287590 Early rheumatoid arthritis. 2005 Nov Longitudinal and observational studies have provided important information on the course of rheumatoid arthritis (RA), clinical outcomes, and prognostic markers. In terms of clinical effectiveness of drugs used in RA, the results of such projects can be used to complement those of randomized studies. If well designed and conducted, inception cohorts are the most robust types of observational studies, reflect the most complete spectrum of disease, and provide the most reliable prognostic markers for the management of this chronic condition.
16966022 Rheumatoid arthritis in dermatology. 2006 Sep Rheumatoid arthritis (RA) is a chronic progressive disorder characterized by symmetric inflammatory arthritis in association with systemic symptoms. Although considered a "joint disease," RA is associated with involvement in diverse organ systems, including the skin. Common manifestations include Raynaud phenomenon, rheumatoid nodules, and rheumatoid vasculitis. As with other extra-articular manifestations, dermatologic involvement tends to occur in patients with more severe RA. In addition to manifestations related to the disease, there are also sundry dermatologic reactions related to the medications used to treat RA. Understanding the etiology and therapy for cutaneous manifestations of RA will help optimize patient care.
15828372 [Rheumatoid arthritis and pregnancy]. 2005 Mar 9 Rheumatoid arthritis occurs frequently in women in childbearing years. With the improvement of the treatments, more patients with rheumatoid arthritis consider a pregnancy. Close co-operation between the physician and the obstetrician caring for the mother and the foetus is necessary. The disease should be well controlled at the time of the conception, although an amelioration of rheumatoid arthritis occurs in about 75% of pregnancies, in the first trimester. Some medications can be used during pregnancy and lactation. There is no indication of any adverse effects of rheumatoid arthritis on pregnancy outcome. The mother needs to be followed up regularly after delivery because of the high risk of post-partum flare.
15887927 Rheumatoid arthritis: an update. 2005 Feb Rheumatoid arthritis is a chronic multi-system disorder of unknown etiology with most common symptoms being persistent inflammatory synovitis, usually involving peripheral joints in a symmetrical pattern. Improved understanding of the molecular mechanisms involved in the pathogenesis of rheumatoid arthritis has led to long awaited, highly effective treatments for this disorder.
15286008 Is rheumatoid arthritis disappearing? 2005 Jan During the past decades a number of studies have examined the incidence of rheumatoid arthritis (RA) in different geographical settings and at different times. Some studies from the 1970s and 1980s reported a higher incidence of RA than seen during recent years, where reported incidence numbers seems to have flattened out at a lower level. Besides a real time dependent decline of RA incidence, changing methodology in classification may be an equally important explanation. Today we may assume that annually 25-50 people from a population of 100,000 will develop typical RA.
16582692 Interleukin-6 in rheumatoid arthritis. 2006 May PURPOSE OF REVIEW: Recent progress in cytokine studies has clarified the pathological roles played by cytokines and provided key evidence that antagonizing their actions can be therapeutic. The pathogenesis of rheumatoid arthritis, an autoimmune inflammatory disease, involves inflammatory cytokines such as tumour necrosis factor-alpha, interleukin-1 and interleukin-6. Anti-tumour necrosis factor-alpha and anti-interleukin-1 therapies have been used successfully to treat rheumatoid arthritis, but they are not consistently effective. We therefore need further therapies for this refractory disease. Interleukin-6 is another target molecule for blockade in the treatment of rheumatoid arthritis. Tocilizumab is a humanized antihuman interleukin-6 receptor monoclonal antibody designed to block the actions of interleukin-6. This review addresses the pathological significance of interleukin-6 and the current status of anti-interleukin-6 therapy for rheumatoid arthritis. RECENT FINDINGS: The safety and efficacy of tocilizumab have been demonstrated in clinical trials conducted in patients with rheumatoid arthritis and other autoimmune inflammatory diseases, such as juvenile idiopathic arthritis and Crohn's disease. SUMMARY: Clinical studies have demonstrated the pathological significance of interleukin-6 and the safety and efficacy of anti-interleukin-6 therapy with tocilizumab. Blockade of interleukin-6 - the second generation of anticytokine therapy - may be a promising treatment for rheumatoid arthritis.
16370926 Tacrolimus in rheumatoid arthritis. 2006 Jan Tacrolimus is an immunosuppressive drug that has been used widely in organ transplantation and topically for atopic dermatitis. Tacrolimus exerts its immunosuppressive effects by the inhibition of calcineurin, leading to interference with T-cell activation. As T-cell activation plays a major role in the pathogenesis of rheumatoid arthritis, there has been an interest in the use of tacrolimus for the treatment of rheumatoid arthritis. The pharmacological properties of tacrolimus have the potential of suppressing the production of inflammatory cytokines, improvement of joint inflammation, improvement of bone and cartilage destruction, improvement of functional status and relief from arthritic pain. This article reviews the pharmacodynamics, pharmacokinetics, clinical efficacy, safety and role of tacrolimus in the treatment of rheumatoid arthritis.
17223742 Adalimumab for rheumatoid arthritis. 2006 Dec In the last few years significant advances have been made in our understanding of the molecular mechanisms underlying rheumatoid arthritis pathogenesis. Pro-inflammatory cytokines, such as TNF-alpha, play a pivotal role in its pathogenesis. Anti-TNF-alpha biological agents are considered a major advance in the treatment of rheumatoid arthritis. Adalimumab is a fully human monoclonal antibody that binds specifically to TNF-alpha, thereby neutralising its activity. It had significant efficacy in well-designed, placebo-controlled trials in patients suffering from rheumatoid arthritis, both as monotherapy and in combination with various disease-modifying antirheumatic drugs, including methotrexate. Adalimumab was generally well tolerated during both concomitant therapy with methotrexate or standard antirheumatic therapy and monotherapy. In addition, the radiographic progression of structural joint damage was significantly inhibited by adalimumab and improved quality of life. This review summarises the recent available data.
16928338 Rheumatoid arthritis and the heart. 2006 Jun The risk of cardiovascular disease is increased in patients with rheumatoid arthritis (RA). Although the pathogenesis of cardiovascular disease in patients with RA is largely unknown, evidence to date indicates that it involves complex interactions between the traditional and nontraditional cardiovascular risk factors as well as various medications commonly used for the treatment of RA patients. This review provides an overview of the clinical studies that demonstrate increased risk of coronary heart disease and heart failure in patients with RA and also discusses the potential role of the various risk factors.
15588970 Does early rheumatoid arthritis exist? 2005 Feb The 'life cycle' of established rheumatoid arthritis can be divided into four phases. The first is the period leading up to the onset of arthritis. The second is the period during which persistence or remission is determined. The third is the evolution into a specific form of inflammatory arthritis, and the fourth is the outcome/severity of that arthritis. In some patients, these four phases follow in rapid succession; however, in other patients, the time course is prolonged over several months or years. This chapter explores the hypothesis that these four phases are distinct in the majority of patients, and that different genetic and environmental factors influence the various phases. It investigates the suggestion that a defect in the hypothalamic-pituitary-adrenal axis may underlie the persistence of inflammatory arthritis. It suggests that the term 'early rheumatoid arthritis' is not appropriate and that patients either have established rheumatoid arthritis or an undifferentiated inflammatory arthritis.
16864922 Pregnancy and rheumatoid arthritis. 2006 Aug Pregnancy in most cases, is associated with remission of rheumatoid arthritis (RA), but a quarter of patients continue to have active disease or even worsening of the disease and most patients who improve, relapse in the postpartum period. The pathophysiology of this improvement in disease activity during pregnancy remains unknown, but hormonal, cell-mediated immunological and humoral immunological changes during pregnancy, have been proposed responsible for this. Most of the pregnant women with RA have an uneventful course, with no significant complications. In general, no significant increase in maternal or fetal morbidity seems to be attributable to RA. Patients with RA do not have decreased fertility. A majority of patients with RA may go in remission and anti-rheumatic treatment may not be required as soon as women become pregnant. But other patients who continue with the disease activity require treatment. The preferred disease-modifying agents during pregnancy are sulfasalazine and hydroxychloroquine. Azathioprine and cyclosporine can be used if the benefits outweigh the risks. Paracetamol and low dose prednisone are preferred and considered safe, both for mother and fetus. Methotrexate and lefunomide are contraindicated and must be prophylactically withdrawn before a planned pregnancy. Biologics generally should be stopped when pregnancy is discovered. An overall rational approach is highly warranted to treat RA during pregnancy.
16991011 [Rheumatoid arthritis and cardiovascular complications]. 2006 Oct Rheumatoid arthritis is associated with increased morbidity and mortality due to cardiovascular events. Elevated concentrations of acute-phase proteins and cytokines and endothelial dysfunction, demonstrated also by lack of traditional risk factors, play an important role in these complications. Antirheumatic drug treatment can modify the frequency and severity of cardiovascular events.
16190501 Diagnosis and management of rheumatoid arthritis. 2005 Sep 15 Rheumatoid arthritis is a chronic inflammatory disease characterized by uncontrolled proliferation of synovial tissue and a wide array of multisystem comorbidities. Prevalence is estimated to be 0.8 percent worldwide, with women twice as likely to develop the disease as men. Untreated, 20 to 30 percent of persons with rheumatoid arthritis become permanently work-disabled within two to three years of diagnosis. Genetic and environmental factors play a role in pathogenesis. Although laboratory testing and imaging studies can help confirm the diagnosis and track disease progress, rheumatoid arthritis primarily is a clinical diagnosis and no single laboratory test is diagnostic. Complications of rheumatoid arthritis may begin to develop within months of presentation; therefore, early referral to or consultation with a rheumatologist for initiation of treatment with disease-modifying antirheumatic drugs is recommended. Several promising new disease-modifying drugs recently have become available, including leflunomide, tumor necrosis factor inhibitors, and anakinra. Nonsteroidal anti-inflammatory drugs, corticosteroids, and nonpharmacologic modalities also are useful. Patients who do not respond well to a single disease-modifying drug may be candidates for combination therapy. Rheumatoid arthritis is a lifelong disease, although patients can go into remission. Physicians must be aware of common comorbidities. Progression of rheumatoid arthritis is monitored according to American College of Rheumatology criteria based on changes in specific symptoms and laboratory findings. Predictors of poor outcomes in early stages of rheumatoid arthritis include low functional score early in the disease, lower socioeconomic status, early involvement of many joints, high erythrocyte sedimentation rate or C-reactive protein level at disease onset, positive rheumatoid factor, and early radiologic changes.
16272271 Rheumatoid arthritis in the cervical spine. 2005 Nov The cervical spine often becomes involved early in the course of rheumatoid arthritis, leading to three different patterns of instability: atlantoaxial subluxation, atlantoaxial impaction, and subaxial subluxation. Although radiographic changes are common, the prevalence of neurologic injury is relatively low. The primary goal of treatment is to prevent permanent neurologic injury while avoiding potentially dangerous and unnecessary surgery. Strategies include patient education, lifestyle modification, regular radiographic follow-up, and early surgical intervention, when indicated. Magnetic resonance imaging is indicated when neurologic deficit (myelopathy) occurs or when plain radiographs show atlantoaxial subluxation with a posterior atlantodental interval < or =14 mm, any degree of atlantoaxial impaction, or subaxial stenosis with a canal diameter < or =14 mm. Surgery should be considered promptly for any of the following: progressive neurologic deficit, chronic neck pain in the setting of radiographic instability that does not respond to nonnarcotic pain medication, any degree of atlantoaxial impaction or cord stenosis, a posterior atlantodental interval < or =14 mm, atlantoaxial impaction represented by odontoid migration > or =5 mm rostral to McGregor's line, sagittal canal diameter <14 mm, or a cervicomedullary angle <135 degrees.
15945214 [Rheumatoid arthritis--clinical picture and important differential diagnoses]. 2005 May Rheumatoid Arthritis is a chronic disease of unknown origin. It affects the joints, but also virtually every other organ. Its cause remains still unknown. The prevalence rate is approximately 1% worldwide, with some racial differences. Women are affected three times more often than men. Symmetric swelling of the joints and a substantial morning stiffness are the typical signs of the disease. Most often the wrists, MCP and PIP joints, and the ankle and MTP joints are affected. The arthritis is usually progressive, leading to destructive changes of the affected joints. Neurological symptoms can occur following destruction of the atlantoaxial joint. Diagnosis and classification of the disease follows the 1987 revised American Rheumatism Association criteria, but for practical purposes the approach described by Visser et al. seems more useful, calculating odds ratios for persisting and erosive disease. Effective treatment can start earlier with this approach. Conventional radiology and serum markers, especially the newer antibodies against CCP are important aids in diagnosing rheumatoid arthritis. Diseases to be separated from rheumatoid are other arthritides of autoimmune origin, the cristal arthropathies, vasculitides, septic and parainfectious arthritides, osteoarthritis, and paraneoplastic syndromes.
