10910181 Parvovirus-associated arthritis. 2000 Jul Human parvovirus B19 is the cause of several distinct clinical syndromes. The most common is erythema infectiosum (fifth disease), a febrile exanthem occurring primarily in children. Recent studies have shown that parvovirus B19 can cause acute arthritis and occasionally a chronic arthropathy, both in children and adults. Parvovirus B19 DNA has been detected in studies in the synovial tissue of patients with rheumatoid arthritis, but other studies have varied in their findings. Recent studies also indicate a possible connective tissue disease-like syndrome with parvoviral infections. The common features of this syndrome are malar eruption, arthralgias, arthritis, and laboratory abnormalities including antinuclear antibody and rheumatoid factor positivity. However, the data indicate it is unlikely that B19 infection causes rheumatoid arthritis or systemic lupus erythematosus. Continued studies of the pathogenesis of acute and chronic parvoviral B19 infections and arthropathy may provide insights into virus-host interactions and mechanisms of joint disease and connective tissue disease.
15775560 [Osteoporosis in rheumatoid arthritis: role of osteoclast differentiation and cytokines]. 2001 May There has been accumulating evidence that osteoclasts, the primary cells responsible for bone resorption, are also involved in bone and joint destruction in rheumatoid arthritis (RA) . Recent progress in bone cell biology has revealed the molecular mechanism of osteoclast differentiation and bone resorption by mature osteoclasts. We here highlight the potential role of RANKL-RANK pathways in bone destruction in RA.
15775555 [Osteoclastic bone resorption in the joint destruction of rheumatoid arthritis]. 2001 May Osteoclastic bone resorption plays a central role in the joint destruction of rheumatoid arthritis patients. Several bone resorptive cytokines are implied to contribute to the mechanism through induction of RANKL/ODF in synovial cells and/or activated T cells. The target of the RA therapy should be focused on this destructive aspect in relation to the original RA pathophysiology.
18020611 Infliximab: a review of its use in Crohn's disease and rheumatoid arthritis. 1998 Nov Infliximab is a chimaeric monoclonal antibody which binds to and inhibits the activity of tumour necrosis factor-alpha (TNFalpha), a cytokine which is involved in the development of both Crohn's disease and rheumatoid arthritis. In patients with treatment-resistant Crohn's disease, infliximab was significantly more effective than placebo in the relief of symptoms. 50 to 89% of patients responded to infliximab and most of them also achieved remission. Patients showed signs of relapse 8 to 12 weeks after a single infusion but responded to additional infusions of the drug. Infliximab was also effective in closing the fistulae in 68% of patients with fistulising Crohn's disease; the response rate with placebo was 26%. Infliximab achieved a clinical response in 44 to 81% of patients with refractory rheumatoid arthritis. Following a single infusion, symptom recurrence was evident after 6 to 12 weeks, but subsequent infusions re-established a clinical response. Concurrent methotrexate appeared to prolong the effects of infliximab in this patient group. Anti-infliximab and anti-double-stranded DNA antibodies developed in some patients, particularly those who received multiple infusions of infliximab. Acute adverse events consistent with hypersensitivity occurred in some patients who received multiple infusions of infliximab. Infection occurred slightly more frequently with infliximab than with placebo. CONCLUSIONS: Infliximab appears to be an effective therapy for patients with treatment-resistant or fistulising Crohn's disease or refractory rheumatoid arthritis. The tolerability, long term efficacy and optimal dosage regimen need to be further defined in comparative trials before the full potential of infliximab is realised in these patients.
28246820 Combined arthroscopic and radiation synovectomy in rheumatoid arthritis. 1998 Mar In rheumatoid arthritis of the knee joint good results are obtained using arthroscopic synovectomy or radiation synovectomy. Aim of our study was to investigate, wether the combination of these two minimal invasive interventions achieves better results. First we performed arthroscopic synovectomy of the knee joint followed by radiation synovectomy with application of 111-222 MBq Yttrium-90 6 weeks later. In a prospective randomised clinical trial between 1987 and 1991 we performed radiation synovectomy on 22 knee joints and combined arthroscopic and radiation synovectomy on 26 knee joints. We explored the patients preoperatively, 6 weeks and 6 months postoperatively. In 1996 we evaluated 141 knee joints in a retrospective clinical trial. 90 Knee joints had been treated with the combined therapy, 39 only with radiation synovectomy and 12 only with arthroscopic synovectomy. Depending on the three different therapeutic interventions, the patients were classified into mid-term (3-5 years) and long-term (6-8 years) observation groups. The trials are based on the standardized ARO-Questionnaire of the knee joint, the modified ARO Knee-Score and the radiological grading according to Larsen, Dale and Eek. In the prospective clinical trial we found significant better results for patients treated with the combined therapy than for patients treated with radiation synovectomy only regarding the parameter swelling, effusion, range of motion, pain and Knee-Score. In the long-term results of the retrospective clinical trial the patients treated with the combined therapy showed a significant better outcome for the parameters pain, swelling and Knee-Score, than the patients treated with radiation synovectomy. Although no statistically significant difference was found comparing the results of the combined therapy with arthroscopic synovectomy, an improvement of the clinical outcome can be observed performing arthroscopic synovectomy followed by radiation synovectomy. In the treatment of rheumatoid arthritis of the knee joint a better outcome is achieved performing combined arthroscopic and radiation synovectomy than performing only one of the methods.
10882215 Sjögren's syndrome: autoimmune epithelitis. 2000 Mar Sjögren's syndrome (SS) is a chronic autoimmune disorder of the exocrine glands of unknown aetiology, which is typically associated with focal lymphocytic infiltrates of glandular tissues and autoantibody responses against the Ro(SSA) and La(SSB) ribonucleoproteins. In almost one-third of patients disease involves various extraglandular sites, whereas approximately 5% of patients may also develop malignant B-cell lymphoma. In addition, features of SS are frequently encountered (5-20%) in patients with several other autoimmune rheumatic diseases, and in several respects these 'secondary' forms may be distinct from SS found alone (primary-SS), as well as from each other. The correct diagnosis and management of SS may require consideration from various specialists. Differential diagnosis includes adverse effects of drugs, sarcoidosis, lipoproteinaemias, age-related atrophy, chronic graft-versus-host disease, lymphomas, amyloidosis and infection by human immunodeficiency virus or hepatitis C virus. Based on the sequential application of the validated European classification criteria for SS, a practical algorithm for diagnosis is presented. Despite progress in the understanding of the broad clinicopathological spectrum of the entity, its treatment remains largely empirical and symptomatic. To date, the decision for systemic therapeutic intervention is primarily based on the severity of extraglandular manifestations.
10503656 Current issues in the diagnosis and treatment of Sjögren's syndrome. 1999 Sep Modification of the European Cooperative Group (EEC) criteria for Sjögren's Syndrome (SS) should lead to less confusion in diagnosis and therapeutic trials. The proposed EEC modification will require either a positive minor salivary gland biopsy or a positive autoantibody against Sjögren's-associated A (Ro) or B (La) antigen. This modification will decrease the proportion of women fulfilling EEC criteria from 3-5% to about 0.5%, which is similar to San Diego and San Francisco criteria. Genetic studies have shown increased frequency of alleles for peptide transporter genes TAP1 (0101) and TAP2 (0101) genes as well as tumor necrosis factor microsatellite a2 alleles. Although these markers confer markedly increased risk, they are found in only a small proportion of patients. An increased frequency of drug (antibiotic) allergy and other allergic manifestations appears present in patients with SS and may be linked to HLA-DR3. Hepatitis C as a cause of sicca symptoms, positive anti-nuclear autoantibodies, and mixed cryoglobulinemia is increasingly reported in different parts of the world. Antibodies against muscarinic M3 receptor and expression of costimulatory molecules (CD80 and CD86) by ductal epithelial cells may play a role in pathogenesis. Treatment with pilocarpine is effective in double-blind trials and low dose oral alpha interferon looks promising in initial open studies. In pregnant patients who exhibit evidence of neonatal heart block, treatment with dexamethasone is preferred over prednisone, since the placenta is unable to metabolically activate the latter compound.
11901709 Thirty two years old patient with adult Still's disease. 2001 Adult Still's disease is characterized by diverse clinical and laboratory findings, which may lead to errors in the differential diagnosis, and possible injury of the patient's health due to wrong therapeutic management. In the following case report, we describe a case of a 32-year old patient with fever of unknown etiology. The final diagnosis of Morbus Still adultorum was determined five months after his first check-up. The course of the disease was complicated by acute hepatitis caused by drug toxic damage. We have applied immunosuppressive therapy with very good clinical and laboratory responses. (Ref. 9.)
9796852 Rheumatoid nodules in a patient with primary antiphospholipid (Hughes) syndrome. 1998 A 29-year-old woman presented with multiple rheumatoid nodules in both hands. Clinical features and supportive laboratory investigations revealed antiphospholipid syndrome. A review of rheumatoid nodules and cutaneous manifestations of antiphospholipid syndrome is presented.
10555914 Remission of juvenile rheumatoid arthritis after infection with parvovirus B19. 1999 Nov A 22-year-old Caucasian woman with a 6 year history of persistently active, systemic onset juvenile rheumatoid arthritis (JRA) developed symptoms of headache, dry cough, nausea, vomiting, abdominal pain, diarrhea, and dehydration associated with a high fever, elevated liver enzymes, and lymphopenia. Subsequent investigation revealed acute infection with parvovirus B19. Following clinical improvement over 10-14 days solely with supportive care, her underlying disease remained in remission for about 7 months.
9987958 [Intravenous immunoglobulin in combined therapy for children with juvenile rheumatoid arth 1998 The study was based on the follow-up of 20 patients with systemic juvenile rheumatoid arthritis who received intravenous immunoglobulin. The study comparatively analyzed the efficiency of the therapy alone and in combination with steroids. The immunoglobulin was shown to have positive effects on both articular and extraarticular manifestations of the disease particularly in a group of children untreated with corticosteroids. The duration of the disease did not affect the therapeutical properties of immunoglobulin.
9564775 [A case of juvenile rheumatoid arthritis with MPO-ANCA associated nephritis]. 1998 Feb A 12-year-old girl with a main complaint of sever pain on the both knees was admitted to our hospital in October, 1995. She gave a three year history of recurrent arthralgia and purpuric rashes, and persistent microhematuria and proteinuria. She developed vesicles and purpuric rashes on the hands and auricles, morning stiffness, fever, uveitis and pericarditis. Laboratory findings showed an elevated level of erythrocyte sedimentation rate and iron-deficiency anemia. Serum perinuclear pattern ANCA with antimyeloperioxidase specificity (MPO-ANCA) was positive. A renal biopsy specimen disclosed a focal and segmental necrotizing glomerulonephritis with crescents. Our case fulfills the both diagnostic criteria for polyarteritis nodosa and juvenile rheumatoid arthritis. This is a rare case of MPO-ANCA associated vasculitis in children.
11935434 Uveitis in juvenile arthritis. 2001 Dec PURPOSE: To evaluate the clinical features of and determine the risk factors for uveitis in patients with juvenile arthritis. METHODS: The prevalence and clinical characteristics of uveitis were studied retrospectively in 90 children diagnosed with arthritis. Patients with uveitis were compared with those who did not have eye involvement. RESULTS: Uveitis was diagnosed in 11 patients (12.2%). Of these, seven (63.6%) had oligoarticular, two (36.4%) had polyarticular, and one (9.1%) had systemic-onset juvenile rheumatoid arthritis (JRA). One patient (9.1%) was diagnosed with enthesitis-related arthritis (ERA) (9.1%). The prevalence of uveitis was significantly higher in patients with oligoarticular JRA. The mean age at onset of arthritis in the uveitis patients was 4.39 years, which was significantly lower than in the non-uveitis group. There was no gender difference in the risk of developing uveitis. Antinuclear antibodies (ANA) was positive in seven (63.6%) of the 11 uveitis patients, confirming ANA as a significant determinant for uveitis in juvenile arthritis. Rheumatoid factor was not found to be a risk factor. One (9.1%) of the 11 patients developed serious sight-threatening complications during the follow-up period. CONCLUSION: This study confirmed that oligoarticular onset, ANA positivity, and young age are risk factors for developing uveitis in patients with juvenile arthritis. Gender was not found to be a determining factor. Prompt treatment of uveitis effectively decreased the prevalence of visual impairment.
9726335 Dactylitis: implications for clinical practice. 1998 Aug OBJECTIVES: To assess the specificity of dactylitis for the diagnosis of spondyloarthropathy, sarcoidosis, and gout; and to characterize dactylitis specifically associated with gout. METHODS: Dactylitis was prospectively assessed among all individuals presenting to the Arthritis Center of Northeast Ohio from 1986 to 1996. RESULTS: Dactylitis was observed in 12% of individuals with spondyloarthropathy, 17% with sarcoidosis, and 5% with gout, but not in 96 patients with rheumatoid arthritis or in 2,434 patients with osteoarthritis, neck or back pain, or collagen vascular diseases. Among individuals with spondyloarthropathy, dactylitis was present in 22% with psoriatic, 28% with Reiter's syndrome, and only 7% with undifferentiated spondyloarthropathy. Gouty dactylitis was found only in individuals with polyarticular disease. CONCLUSIONS: Dactylitis is a valuable clue in the differential diagnosis of arthritis. Compared with the wider spectrum in children, sausage-shaped digits have only a few known causes in adults: Reiter's syndrome, psoriatic arthritis, sarcoidosis, flexor tendon sheath infections, and gout. In our series, the presence of dactylitis eliminated rheumatoid arthritis from the differential diagnosis.
9782809 Arthritis health service utilization among the elderly: the role of urban-rural residence 1998 Jun OBJECTIVE: To compare the impact of urban-rural residence and other factors on the utilization of any type of arthritis-related physician care and on rheumatologist utilization. METHODS: A population-based random sample of adults 65 years of age or older with self-reported arthritis from 10 urban and 12 rural Iowa counties were surveyed by telephone interview. We estimated the arthritis prevalence and health service utilization in this sample and evaluated the effects of predisposing, enabling, and need factors on utilization and satisfaction. Health care utilization was defined as ever having visited specific types of providers for arthritis-related care. RESULTS: A total of 488 individuals participated: 227 from urban counties and 261 rural respondents. Urban respondents more commonly reported having received a diagnosis of osteoarthritis from their physicians but were less likely to report rheumatoid arthritis. A greater proportion of urban versus rural respondents had utilized any physician for arthritis care (50.7% versus 41.0%, P = 0.032) and had more often seen an orthopedist (18.1% versus 9.6%, P = 0.006) or general internist (18.5% versus 8.8%, P = 0.002). A diagnosis of rheumatoid arthritis, younger age, living with another person, higher income, and further distance from an arthritis provider were significantly associated with prior rheumatologist utilization. The strongest adjusted predictor of any physician visit for arthritis care was whether older adults drove themselves to their provider. For rheumatologist utilization, a diagnosis of rheumatoid arthritis and age were independently associated. CONCLUSIONS: The most striking finding was the consistent association of need factors (such as the desire for medical advice), joint swelling, and the presence of a diagnosis of rheumatoid arthritis with physician utilization. We identified significant urban-rural variations in factors both enabling and predisposing to arthritis care, although urban-rural status did not appear to independently influence arthritis physician utilization. In a rural state with a relatively small number of rheumatologists, deleterious enabling factors such as greater distance from the doctor and lack of supplemental insurance did not provide significant obstacles to either rheumatologist or generalist utilization.
24387016 Gastrointestinal disorder and Helicobacter pylori infection in patients with rheumatoid ar 2001 Mar Abstract Gastrointestinal disorders such as gastritis and peptic ulceration are very common in patients with rheumatoid arthritis. Helicobacter pylori appeared to be a high risk factor for the development of peptic ulcers or chronic active gastritis. Thus, the objective of this study is to elucidate gastrointestinal findings and the prevalence of H. pylori in patients with rheumatoid arthritis. Consecutive RA patients were recruited for this study, irrespective of gastrointestinal symptoms. Routine endoscopy was performed and mucosal specimens were analyzed according to the Sydney system. H. pylori infection was determined histologically using H-E staining, Wartin Starry silver staining, and immunohistochemistry. Of 97 patients, only 16 had gastrointestinal symptoms. By endoscopic examination, gastritis was observed in 39 patients (40.2%), gastric ulcers in 24 patients (24.7%), and duodenal ulcers in 7 patients (7.2%). The histological results analyzed by the Sydney system showed "inflammation," "active," and "atrophy" for 71.1%, 58.5%, and 54.6% of samples, respectively. Sixty patients (61.9%) were infected by H. pylori, but the presence of H. pylori did not increase the chance of endoscopic gastrointestinal disorders. The presence of a rheumatoid factor was inversely related to H. pylori infection, and the value of the rheumatoid factor was lower in patients with the infection. In conclusion, it was found that H. pylori infection was not a major cause of gastrointestinal disorders in RA, and that the presence of rheumatoid factor significantly reduces the chance of H. pylori infection.
21781798 Food sensitivity and rheumatoid arthritis. 1997 Nov The majority of double-blind placebo-controlled trials have shown that 30-40% of rheumatoid arthritis (RA) patients can improve substantially by using an elimination diet to identify foods that precipitate symptoms and the avoiding of these foods. Some such patients have discontinued drug treatment and remained well for 12 years or more. Prior to the elimination diet, most patients had not recognised diet as a trigger for their symptoms, because the offending foods were eaten daily. (Foods eaten infrequently can also provoke sensitivity, resulting in episodic arthritis.) Additionally, many RA patients are sensitive to several foods, making a rigorous elimination diet essential for diagnosis. The pattern of response to an elimination diet (30-40% of RA patients respond well; response occurs within 10-21 days; benefits are maintained if offending foods are avoided) is markedly different from the pattern of response to a fast (almost all RA patients respond well; response occurs within 3-5 days; benefits are lost rapidly when a normal diet is resumed). Clearly fasting and the elimination diet have different therapeutic mechanisms. The effect of fasting may be mediated by the absence of dietary fat, leading to a shortage of pro-inflammatory prostaglandins and leukotrienes. The mechanism by which food sensitivity is involved in rheumatoid arthritis remains unknown, but weight loss is definitely not responsible for the improvement seen on an elimination diet. Some evidence implicates the gut flora. Food-sensitive RA patients may also show changes in immune parameters during an elimination diet, but no consistent universal change has yet been found.
11260975 [Articular involvement in the course of primary hypogammaglobulinemia]. 2001 Jan The Authors describe the main features of the most common forms of primary hypogammaglobulinaemia (PH) focusing on the articular involvement. Patients with Bruton's agammaglobulinemia (BA) and common variable immune deficiency (CVID) are predisposed to develop septic arthritis (including arthritis due to atypical microorganisms such as mycoplasma), arthralgia and symmetrical (usually non-erosive) polyarthritis. In BA and CVID complicated by recurrent infections, amyloidosis, which may be itself a cause of arthropathy, can occur. In addition, patients with CVID and selective IgA deficiency show an increased prevalence of juvenile rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome and primary biliary cirrhosis, while patients with selective IgA deficiency are prone to developing seronegative spondylarthropathies, including ankylosing spondylitis. The mainstay of treatment for BA and CVID is replacement therapy with human immunoglobulins. Septic arthritis should be promptly treated with antibiotics, whereas other types of arthritis usually respond well to non-steroidal antiinflammatory medications. In contrast, the second line agents commonly used to treat rheumatoid arthritis do not appear to be beneficial in patients with PH-associated arthritis.
11914477 Juvenile rheumatoid arthritis with amyloid goiter: report of a case with review of the lit 2001 Winter Clinically significant enlargement of the thyroid owing to amyloid deposition is a rare occurrence. A 23-yr-old female, a case of juvenile rheumatoid arthritis, developed rapidly increasing thyromegaly during the course of her illness with complaints of dyspnea and dysphagia. Thyroid function tests were within normal limits. Fine-needle aspiration cytology proved inconclusive. Total thyroidectomy was done for symptomatic relief with a preoperative clinical impression of malignancy. Histopathologic findings were consistent with amyloid goiter. The findings of this case are presented, to emphasize the difficulties in making a definite preoperative diagnosis, along with a brief review of the literature.
9383925 Juvenile rheumatoid arthritis: benefits from massage therapy. 1997 Oct Studied children with mild to moderate juvenile rheumatoid arthritis who were massaged by their parents 15 minutes a day for 30 days (and a control group engaged in relaxation therapy). The children's anxiety and stress hormone (cortisol) levels were immediately decreased by the massage, and over the 30-day period their pain decreased on self-reports, parent reports, and their physician's assessment of pain (both the incidence and severity) and pain-limiting activities.
