19707469 | Rituximab therapy in Greek patients with rheumatoid arthritis. | 2008 Dec | OBJECTIVE: An open-label, prospective, uncontrolled study created to investigate clinical response, serological changes and side effects in Greek patients with rheumatoid arthritis (RA), after B-cell depletion with rituximab. METHODS: Patients with high disease activity (disease activity score [DAS]-28 > 5.1) were selected for treatment with rituximab and received two infusions, 1 gr each, 2 weeks apart. Different disease parameters (visual analog scale, DAS-28, C-reactive protein [CRP], erythrocyte sedimentation rate, health assessment questionnaire, complement (C3), C4, rheumatoid factor [RF], anti-cyclic citrullinated peptide antibody [anti-CCP], swollen joint count, tender joint count, immunoglobulin M [IgM], IgG, IgA) were performed at base line, 2, 4, and 6 months post-treatment. Response was defined according to the American College of Rheumatology (ACR) criteria. RESULTS: Seventeen patients received therapy. Treatment led to a reduction in various disease parameters. ACR20 was achieved in 41.11% of patients by week 8, 52.94% by week 16, and 82.35% by week 24. ACR50 was achieved in 5.88% by week 8, 41.17% by week 16, and 64.7% by week 24. ACR70 was achieved only by week 24 in 23.52% of patients. Statistical analysis has shown no differences in clinical response, between RF positive/negative patients, and anti-CCP-positive/negative patients, while decline of RF was better correlated with reduction of DAS-28 than with anti-CCP. CONCLUSIONS: Rituximab is a well tolerated and effective treatment in RA. Response was not correlated to RF or anti-CCP positivity. Decline of RF was associated with clinical response and reduction of DAS-28 and CRP. | |
17173765 | [Adult Still's disease with atypical skin manifestations]. | 2006 Nov | Adult Still's disease (ASD) is an uncommon inflammatory disease of unknown etiology. It is characterized by the triad of intermittent high fever, evanescent rash and polyarthralgia or polyarthritis. We present the case of a 29-year-old woman with ASD and persistent erythematous papule on neck and upper part of the trunk. The presence of fixed lesions is not characteristic of ASD, but its appearance during development of the disease suggests that they are a manifestation of it. Recently, other skin manifestations of ASD have been published, but they are not well-known. | |
16503880 | Primary Gougerot-Sjögren syndrome: a dermatological approach. | 2006 Mar | Gougerot-Sjögren syndrome (GSS) is a chronic heterogeneous non-organ-specific autoimmune disease, encompassing a wide spectrum of clinical manifestations. It is characterized by a lymphocytic infiltration of the exocrine glands, also called epitheliitis, resulting in xerostomia and keratoconjunctivitis sicca. The skin can also be involved; for example, xerosis is a consequence of epitheliitis. Dermatological consequences of polyclonal reactivity are vasculitis and manifestations of B-cell proliferation vary from plasma cell infiltrates to B-cell lymphoma. | |
18360649 | Abatacept in the treatment of rheumatoid arthritis. | 2006 Dec | Abatacept (CTLA4-Ig) is a new agent which targets T-cell activation, an event which is thought to be critical to the onset and maintenance of rheumatoid arthritis (RA). Abatacept now has substantial evidence from phase III trials for efficacy in patients with RA who have failed to respond to disease-modifying antirheumatic drugs (DMARDs) and antitumor necrosis factor-alpha (TNF-alpha) biologic agents. Safety profile is favorable in combination with DMARDs. The mechanism of action and available evidence of its efficacy and safety are reviewed in this article. | |
21475473 | Effect of allopurinol and vitamin e on rat model of rheumatoid arthritis. | 2008 Jan | OBJECTIVES: Rat collagen II-induced arthritis is a model of chronic inflammation induced by mycobacterium butyricum and collagen II. It is characterized by similar pathophysiological and pathobiochemical changes as rheumatoid arthritis (RA) in humans. In the present study, the biochemical effects of vitamin E and allopurinol (Allo) on RA of rats were investigated. METHODS: Forty male rats were divided into four groups (10 rats each): control group, collagen II-induced RA group (CII group), CII group treated with allopurinol (CII+ Allo), and CII group treated with vitamin E (CII + Vit E). After 6 weeks of treatment, the plasma levels of lipid peroxides (LPO), nitric oxide (NO), ceruloplasmin (CP), superoxide dismutase (SOD), uric acid (UA) and glutathione (GSH) were detected using colorimetric methods. The plasma levels of PGE2 were measured using ELISA assay. The plasma levels of copper (Cu) and zinc (Zn) were determined using atomic absorption spectrometer. RESULTS: In CII treated group, the levels of LPO, NO, PGE2, UA, CP and Cu were significantly higher, but the levels of SOD, GSH and Zn were significantly lower than controls. In CII + Allo treated group, the levels of SOD and GSH were significantly increased, but the levels of PGE2, LPO, NO, UA, Cu and CP were significantly decreased in comparison with CII-treated group. The levels of SOD, GSH and Zn were significantly increased, but the levels of PGE2, NO and CP were significantly decreased in the vitamin E treated group in comparison with CII-treated group. The levels of PGE2, LPO, Cu and Zn were significantly lower in vitamin E treated group than Allo-treated group. In conclusion, the study suggests that proper antioxidant intake management may reduce free radical generation and improve antioxidant status in RA. Allopurinol and vitamins E may effectively normalize in different degrees the impaired the oxidant/antioxidant system and may be useful in delaying the complication of RA. Moreover, they display anti-inflammatory action by decreasing PGE2 level in RA. | |
18299022 | The rheumatic causes of elbow instability. | 2008 Feb | Rheumatoid arthritis is the most common cause of elbow instability, but other causes include other erosive arthritides and noninflammatory diseases. Surgical consultation should be obtained for refractory pain or disability, or when physical examination or imaging reveals instability, erosions, or impending pathologic fracture. Medical management for rheumatoid arthritis includes early treatment and combination therapy, including biologic response modifiers. Current recommendations for rheumatic medicines, including perioperative use, are discussed. | |
16906368 | Cartilage destruction by matrix degradation products. | 2006 | The progressive destruction of articular cartilage is one of the hallmarks of osteoarthritis and rheumatoid arthritis. Cartilage degradation is attributed to different classes of catabolic factors, including proinflammatory cytokines, aggrecanases, matrix metalloproteinases, and nitric oxide. Recently, matrix degradation products generated by excessive proteolysis in arthritis have been found to mediate cartilage destruction. These proteolytic fragments activate chondrocytes and synovial fibroblasts via specific cell surface receptors that can stimulate catabolic intracellular signaling pathways, leading to the induction of such catalysts. This review describes the catabolic activities of matrix degradation products, especially fibronectin fragments, and discusses the pathologic implication in cartilage destruction in osteoarthritis and rheumatoid arthritis. Increased levels of these degradation products, found in diseased joints, may stimulate cartilage breakdown by mechanisms of the kind demonstrated in the review. | |
16625453 | [Current status of wrist arthrodesis]. | 2006 Mar | AIM: In order to ascertain the value and future of wrist arthrodesis we assessed the results of 47 wrist arthrodeses performed at the Departments of Orthopaedic and Trauma Surgery of the University of Goettingen between 1980 and 1998. METHOD: In a retrospective analysis we examined the patients clinical and radiological records. Evaluating the results we used the score described by Lohmann and Buck-Gramcko in order to consider function, pain, strength and assessment of the patient him/herself. RESULTS: 93.6 % of all cases could be examined. We found a wrist arthrodesis in posttraumatic arthritis in 22 cases and in rheumatoid arthritis in 25 cases. Plate (n = 30) and Rush-Pin osteosynthesis (n = 17) were used as surgical procedures. In all patients we found a successfully stabilised wrist, although in 3 trauma cases a further surgical procedure was necessary. A better function of the wrist was reached in every patient. The majority of the patients had no pain and an acceptable strength. The results obtained showed good and excellent results in 86.4 % of the wrist arthrodesis for post-traumatic arthritis and in 90.9 % for rheumatoid arthritis. CONCLUSION: The increase in quality of life, especially in patients suffering from rheumatoid arthritis, shows the procedure of wrist arthrodesis to be a still worthwile surgery. | |
17502305 | [Diagnosis of adult-onset Still's disease: contribution of biology]. | 2007 May | We report one case of adult-onset Still's disease. The diagnosis of this disease currently requires application of Yamaguchi's criteria and then exclusion of infectious, haematological, autoimmune and neoplasic disorders. The place of biology is enhanced with the use of new markers like ferritin and glycosylated ferritin. Low percentage of glycosylated ferritin (<20%) in presence of very high level of ferritin, unexplained prolonged fever with leukocytosis can help to diagnosis. However, glycosylated ferritin is not yet of in routine use. | |
16932698 | The management of Sjögren's syndrome. | 2006 May | Sjögren's syndrome is a chronic autoimmune disorder, characterized by lymphocytic infiltration and malfunction of the exocrine glands, resulting in dry mouth and eyes. The syndrome can present either alone (primary Sjögren's syndrome) or in the context of an underlying connective tissue disease (secondary Sjögren's syndrome). Systemic features, resulting from cutaneous, respiratory, renal, hepatic, neurologic, and vascular involvement, often occur. Two types of primary Sjögren's syndrome are currently recognized: a benign disease that affects quality of life, and a systemic syndrome associated with increased morbidity and mortality owing to a high risk of malignant transformation, and that requires close follow-up. Ocular involvement, manifested as keratoconjunctivitis sicca, is managed with local and systemic stimulators of tear secretion and supportive surgical procedures. Treatment of oral manifestations includes intense oral hygiene, prevention and treatment of oral infections, use of saliva substitutes, and local and systematic stimulation of salivary secretion. Cholinergic agents, such as pilocarpine and cevimeline, are helpful in patients with residual salivary function, and ciclosporin ocular drops seem to be of some benefit. Systemic immunosuppressives are reserved for treatment of severe extraglandular manifestations of Sjögren's syndrome. Anti-B-cell therapy is a new potential therapy for the glandular and extraglandular manifestations, such as glomerulonephritis or vasculitis, in addition to the management of lymphoma associated with Sjögren's syndrome. Induction of oral tolerance and gene-transfer modalities were recently attempted in animal models, with promising results. | |
16469087 | Adult-onset Still's disease with prurigo pigmentosa-like skin eruption. | 2006 Jan | A 34-year-old woman with adult-onset Still's disease (AOSD) developed prurigo pigmentosa-like lesions on her chest and upper back in addition to the typical rash of AOSD. A biopsy specimen taken from the upper back showed characteristic features of prurigo pigmentosa. The eruption and fever subsided immediately after the administration of 40 mg/day prednisolone, but arthralgia persisted even after intravenous pulse methylprednisolone therapy in combination with immunosuppressive drugs. Various atypical skin rashes, including prurigo pigmentosa-like lesions, have been reported in association with AOSD. Therefore, one should carefully follow the clinical course of a patient in order not to overlook these atypical cutaneous manifestations of AOSD. | |
17921792 | Partial C4 deficiency in juvenile idiopathic arthritis patients. | 2007 Oct | OBJECTIVES: C4 is encoded by 2 distinct but closely linked loci within the major histocompatibility complex locus on human chromosome 6. C4A deficiencies have been associated with autoimmune disease and C4B with increased frequency of infection. C4 deficiencies have rarely been associated with juvenile idiopathic arthritis (JIA). Our aim was to investigate the prevalence of deficiencies in C4 allotypes in JIA patients. METHODS: We evaluated 61 patients [35 JIA patients, 15 systemic lupus erythematosus patients, 9 rheumatoid arthritis patients, and 2 mixed connective tissue disease (CTD) patients] for C4 deficiency. Genomic DNA was isolated from whole blood and subjected to polymerase chain reaction using sequence-specific primers for C4 allotypes. RESULTS: We found 5 JIA patients with C4 deficiencies. Two IgM rheumatoid factor-positive JIA polyarthritis patients had C4 deficiencies, one with complete C4A deficiency and another with partial C4A and complete C4B deficiency. Two oligoarthritis patients displayed partial C4B deficiencies, and complete C4B deficiency was revealed in 1 IgM rheumatoid factor-negative polyarthritis patient. Three patients had histories of recurrent infections and 2 demonstrated a more severe disease course. Disease controls showed 8 systemic lupus erythematosus patients had partial C4 deficiencies, whereas no deficiencies were revealed in the rheumatoid arthritis or mixed CTD patients. CONCLUSIONS: Defects in the complement system have been implicated in the pathogenesis of CTD. However, the specific role of C4 in JIA is not clear. We demonstrate partial C4 deficiencies in 5 JIA patients. Our findings suggest an association between C4 deficiency and another CTD, JIA, as well as with disease severity and recurrent infections. | |
21901078 | Platelet-derived growth factor as a therapeutic target for systemic autoimmune diseases. | 2007 | Some systemic rheumatic diseases and disorders, especially fibrotic and vascular disorders, are often refractory to corticosteroid therapy. Recently, ever accumulating evidence suggests that platelet-derived growth factor (PDGF) is involved in those refractory diseases. Imatinib mesylate inhibits the activation of PDGF receptor as well as c-Abl, Bcr-Abl and c-Kit tyrosine kinases. It has therefore been widely used for the treatment of chronic myeloid leukemia and gastrointestinal stromal tumors. Imatinib effectively suppresses the activation and proliferation of fibroblasts, mesangial cells and smooth muscle cells both in vitro and in vivo. Additionally, it has recently been reported that some patients with rheumatoid arthritis or idiopathic pulmonary arterial hypertension demonstrated a good clinical response to imatinib therapy. Imatinib may therefore overcome the limitations of current therapeutic strategy with corticosteroids and immunosuppressive agents for refractory diseases, such as systemic sclerosis and interstitial lung diseases, without clinical intolerability. | |
23674987 | Metacarpal Index Estimated by Digital X-ray Radiogrammetry as a Tool for Differentiating R | 2006 Sep | To investigate Metacarpal Index (MCI) and Bone Mineral Density (BMD) estimated by Digital X-ray Radiogrammetry (DXR) with respect to its ability to quantify severity-dependent variations of bone mineralisation in patients with early rheumatoid arthritis compared to Dual Energy X-ray Absorptiometry (DXA), 122 patients underwent a prospective analysis of BMD and MCI by DXR, whereas both DXR-parameters were estimated from plain radiographs of the non-dominant hand. In comparison DXA measured BMD on total femur and lumbar spine (L2-L4). Additionally Steinbrocker Stage was assessed to differentiate the severity of rheumatoid arthritis (RA). Disease activity of RA was estimated by C-reactive Protein (CRP; in mg/l), Erythrocyte Sedimentation Rate (ESR in mm/1st hour) and by the disease activity score with 28-joint count (DAS 28). In consequence, The DXR-parameters, in particular DXR-MCI, revealed significant associations to age, Body Mass Index, CRP, DAS 28 and Steinbrocker graduation; no significant associations could be verified between DXA-parameters and all characteristics of disease activity and severity of RA. The highest correlation was found between DXR-MCI and DXR-BMD with R=0.89 (independent from severity of RA). In all patients DXR-MCI significantly decreased (-14.3%) from 0.42 ± 0.09 (stage 1) to 0.36 ± 0.07 (stage 2) dependent on severity of RA. The comparable relative reduction of DXR-BMD was -11.1%. The group of patients with minor disease activity (DAS 28>5.1) showed a significant flattened reduction (-11.4%) for DXR-MCI from 0.44 ± 0.08 (stage 1) to 0.39 ± 0.08 (stage 2). For accentuated disease activity (DAS 28>5.1) the DXR-MCI revealed a pronounced reduction (-23.1 %). No significant declines were observed for DXA-BMD of the lumbar spine and total femur in all patients as well as dependent on disease activity. CONCLUSION: DXR can exactly quantify cortical thinning of the metacarpal bones and can identify cortical demineralisation in patients suffering from early rheumatoid arthritis surpassing DXA-measurements at axial bone sites. In this context DXR-MCI seems to be the most sensitive parameter for differentiation of patients with minor or accentuated disease activity following severity-dependent cortical bone loss. | |
18418614 | [Elevated liver enzymes in rheumatoid arthritis : differential diagnostic considerations b | 2008 Sep | Elevated liver enzymes in patients with rheumatoid arthritis may have various causes. These can range from the rheumatic disease itself, the anti-rheumatic medication or be the manifestation of an associated autoimmune disease. We present the case of a 19-year-old female with known seropositive rheumatoid arthritis who developed severe liver damage after 9 months of anti-rheumatic therapy with leflunomide and adalimumab. Both drugs were stopped. In addition to the underlying disease and the specific anti-rheumatic drugs, a temporary therapy with flucloxacillin as well as an association with newly diagnosed celiac disease had to be considered as possible causes of elevated liver enzymes. Following repeated liver biopsy, autoimmune hepatitis was assumed and prednisolone and azathioprine were initiated. Elevated liver enzymes and bilirubin rapidly returned to normal values. | |
19156223 | Factor structure of the arthritis body experience scale (ABES) in a U.S. population of peo | 2008 | OBJECTIVE: To examine the psychometric properties of the Arthritis Body Experience Scale (ABES) in a US sample of people with osteoarthritis, rheumatoid arthritis, fibromyalgia and other rheumatic conditions. METHODS: The ABES, with the scoring direction modified, was phone-administered to 937 individuals who self-identified as having one or more arthritis conditions based on a validated, US, national survey assessment tool. Descriptive statistics of demographic variables and factor analysis of scale items were conducted. Scale dimensionality was assessed using principal component analysis (PCA) with oblique rotation. Criteria for assessing factors were eigenvalues > 1, visual assessment of scree plot, and structure and pattern matrices. RESULTS: The predominantly female (74.2%) and Caucasian (79.9%) sample had a mean age of 61.0 ± 13.1 years, and a mean BMI of 30.2 ± 7.1. Major arthritis conditions reported were rheumatoid arthritis, osteoarthritis and fibromyalgia. A three-factor structure with cronbach alpha values of .84, .85 and .53 was elicited, and accounted for 72% of the variance. DISCUSSION: Compared to the two-factor structure evidenced by the original ABES scale in a sample of UK adults, the data from this sample evidenced a three-factor structure with higher variance. The third factor's cronbach alpha of .53 was low and could be improved by the addition of salient questions derived from further qualitative interviews with patients with arthritis and other rheumatic conditions and from current literature findings. CONCLUSION: The observed psychometrics indicate the scale usefully assesses body image in populations with arthritis and related conditions. However, further testing and refinement is needed to determine its utility in clinical and other settings. | |
21919249 | Rheumatoid Arthritis Medicines: A Guide for Adults . | 2005 | This guide can help you work with your doctor or nurse to find a medicine for rheumatoid arthritis (RA). It is a lifelong condition. RA causes inflammation (swelling, redness, and pain) that can damage the joints. No treatment can cure RA. But the drugs in this guide can slow down the disease and help you feel better. This guide is based on a government-funded review of research about RA medicines. Besides helping you learn about what happens with RA, this guide explains the benefits, risks, and costs of RA drugs. | |
20528534 | Economic burden of rheumatoid arthritis in France. | 2006 Feb | In France, few economic assessments on the cost of rheumatoid arthritis have been undertaken. Descriptive cost studies were available with different methodological approaches (prospective vs retrospective, economic and/or medical assessment, analytical economic assessment of the cost vs tariff per diagnosis-related group for calculation of hospital costs, based on inpatient and/or outpatient records, focused on diagnosis and/or treatment, and based on real vs theoretical practice) at different times, especially compared with the daily availability of biotherapy or the phase of change of the French Health System financing. Direct medical costs were primarily described. Medicoeconomic assessment should be continued when the disease prognosis is altered by the administration of a new but expensive therapy (i.e. biotherapy) and focused on direct and indirect costs. The ESPOIR and the VERA cohort studies of recent arthritis patients, recently initiated in France, will be useful database contributors. In parallel with the hospitalizations for rheumatoid arthritis extracted from the French national hospital database, a national register is required to follow the administration of biotherapy. As the French Health System is currently changing, some methodological approaches of economic assessment were proposed. Further studies need to be conducted according to guidelines for economic evaluation to allow relevant economic data at country level and for international comparison. | |
16584079 | Orthopedic surgical management of hip and knee involvement in patients with juvenile rheum | 2006 Feb | Juvenile rheumatoid arthritis is the most common arthritic disease of childhood and a leading cause of childhood disability, affecting an estimated 300,000 US children and adolescents aged < or =16 years. Approximately 10% to 30% of patients experience functional deficits resulting from both the articular and systemic manifestations of their disease, including leg length inequality and deformity, that are often more crippling than joint destruction. Surgical intervention to treat bone and soft-tissue deformity, leg length inequality, and joint destruction is indicated when medical therapy has failed. Synovectomy, soft-tissue release, osteotomy, and epiphysiodesis are used to treat deformity and early joint destruction. Arthroplasty remains the primary therapy for joint destruction, although it is fraught with complications specific to this young patient population. | |
21794301 | [Atypical pulmonary nodules in a patient with rheumatoid arthritis]. | 2006 Jan | Rheumatoid arthritis (RA) is associated with a wide variety of lung manifestations, including rheumatoid nodules. We report the case of woman with a diagnosis of RA who underwent thoracic computed axial tomography (CAT) scan because of cough and effort dyspnea. The CAT scan revealed the presence of small lung nodules. After biopsy, these nodules were diagnosed as cholesterol granulomas. |
