Abstract: BACKGROUND: Our objective was to assess the efficacy and safety of cyclosporine-A (CsA) plus chloroquine (Clq) in early-onset rheumatoid arthritis (RA) compared to CsA plus placebo. METHODS: We conducted a prospective, 12-month follow-up, multicenter, double-blind, placebo-controlled study of CsA (2.5-5 mg/kg/day[d]) plus Clq (150 mg/d) vs. CsA plus placebo in active RA of <2 years of evolution. RESULTS: A total of 149 patients were included; 111 patients (74.4%) completed the 12-month follow-up period. Evaluation at 6 and 12 months showed improvement for all clinical disease parameters. In both groups there was a decrease in tender joint count, swollen joint count, pain, assessment of efficacy by both investigator and patient, functional assessment, and morning stiffness, all differences statistically significant. With an intention-to-treat analysis, there was 64% in the CsA plus Clq group (CsA/Clq) and 63% in the CsA plus placebo group (CsA/Plac) at 12 months in the American College of Rheumatology (ACR)-20 criteria of improvement. Response rate for ACR-50 was 48 and 47%, and for ACR-70 it was 29% in both groups; the difference was not statistically significant between study groups. Gastrointestinal complaints were common in both groups. Four patients in CsA/Clq group and five patients in CsA/placebo group increased creatinine levels; two patients in each group discontinued treatment due to this reason. CONCLUSIONS: There was no advantage to adding chloroquine to cyclosporine in patients with RA.

Abstract: OBJECTIVE: To evaluate the long-term efficacy and safety of etanercept in children with juvenile rheumatoid arthritis (JRA) participating in an ongoing multicenter, open-label, extended-treatment trial. All patients had been participants in an initial randomized efficacy and safety trial of etanercept. METHODS: Etanercept was administered at a dosage of 0.4 mg/kg (maximum 25 mg) subcutaneously twice each week. Safety and efficacy evaluations were performed every 3-4 months. The JRA 30% definition of improvement (DOI) was defined as improvement of > or =30% in at least 3 of 6 response variables used to assess disease activity, with no more than 1 variable worsening by more than 30%. RESULTS: At the time of analysis, 48 of the 58 patients (83%) were still enrolled in the study; 43 of them (74%) had completed 2 years of treatment. Of these 43 patients, 81% met the JRA 30% DOI, 79% met the JRA 50% DOI, and 67% met the JRA 70% DOI. Ten children started low-dose methotrexate after year 1. Of the 32 children taking prednisone, the dosage was decreased to <5 mg/day in 26 (81%). Two children had serious infections (varicella with aseptic meningitis in one and complicated sepsis in the other). In general, adverse events were of the types seen in a general pediatric patient population. CONCLUSION: Children with severe, longstanding, methotrexate-resistant polyarticular JRA demonstrated sustained clinical improvement with >2 years of continuous etanercept treatment. Etanercept was generally well-tolerated. There were no increases in the rates of adverse events over time. However, children taking etanercept should be monitored closely for infections.

Abstract: INTRODUCTION: The objective was to study the potential genetic contribution of Toll-like receptor (TLR) genes in rheumatoid arthritis (RA). TLRs bind to pathogen-associated molecular patterns, and TLR genes influence both proinflammatory cytokine production and autoimmune responses. Host-pathogen interactions are involved in RA physiopathology. METHODS: We tested SNPs of five TLR genes (TLR9, TLR2, TLR6, TLR1, and TLR4) in a cohort of 100 French families with RA. Genotypes were analyzed using the transmission disequilibrium test. As TLR2, TLR6, and TLR1 are located on chromosome 4, we determined the haplotype relative risk. Analyses were performed in subgroups defined by status for rheumatoid factor, anti-cyclic citrullinated peptide autoantibodies, and erosions. RESULTS: We found no disequilibrium in allele transmission for any of the SNPs of the five TLR genes. In subgroup analyses, no associations were detected linking TLR9, TLR2, or TLR9/TLR2 to rheumatoid factor, anti-cyclic citrullinated peptide autoantibodies, or erosions. Haplotype analysis of the polymorphisms showed no haplotype associations in any of the subgroups. CONCLUSIONS: We found no evidence of major effects of TLR gene polymorphisms in RA, although we tested different TLR phenotypes. Moreover, no associations were noted with autoantibody production or erosions.

Abstract: The aim of the present study was to assess the health-related quality of life (HRQoL) in patients with common rheumatic diseases referred to a rheumatology clinic and to compare it to the HRQoL of the general population. All patients with a new referral to the Department of Rheumatology of the Helsinki University Central Hospital were asked to participate in the study during the period from May 2002 to April 2003. A total of 295 patients with various rheumatic diseases were included in the analysis: 99 patients with rheumatoid arthritis (RA), 47 with arthralgia and fibromyalgia, 43 with other chronic arthritis (spondyloarthritis, psoriatic arthritis, enteropathic arthritis), 44 with osteoarthritis (OA), 22 with active reactive arthritis (ReA), 17 with systemic rheumatic diseases, 9 adults with juvenile idiopathic arthritis (JIA) and 14 with other diagnoses. HRQoL was measured by a disease specific instrument, the Stanford health assessment questionnaire (HAQ) and by a generic instrument, 15D. The mean baseline 15D score of the 295 included patients (0.822, SD 0.114) was significantly lower than of the general population (0.903, SD 0.098). Patients with OA and chronic arthritis reported the poorest HRQoL scores (both 0.810 on a 0-1 scale). In patients with RA and ReA the 15D score improved in a statistically significant and clinically important manner during the 8-month follow-up. Discomfort and symptoms caused by the disease were alleviated in a statistically significant manner in patients with RA as well as in those with arthralgia and fibromyalgia, chronic arthritis, ReA and systemic rheumatic diseases. HAQ score improved significantly in patients with RA, arthralgia and fibromyalgia, and ReA. The HRQoL of patients with common rheumatic diseases at referral to rheumatology clinic is significantly lower than the HRQoL of age-standardized general population. The most affected patients are those with OA, chronic arthritis and RA. A significant improvement in HRQoL with conventional interventions was achieved in patients with RA and ReA.

Abstract: OBJECTIVE: To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS: Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ). Those who had improved by at least 0.25 HAQ were analyzed for possible predictors of DAS28 remission at the sixth month. RESULTS: A total of 1257 patients started TNF-alpha blockers. Of these, 591 (46.7%) reached the sixth month with an improvement of HAQ of 0.25 at the third month. In the cohort of patients reaching HAQ of 0.25, DAS28 remission was seen in 24% of rheumatoid factor (RF)-positive and 36% of RF-negative patients (p = 0.03). Logistic regression analysis for predictors of remission identified age at baseline, HAQ < 1.63, and RF negativity as positive predictors of remission at 6 months along with sex (male). CONCLUSION: We show that only a minority of patients with longstanding RA achieve a good clinical response or remission at the outpatient community level. Predictors of remission identify characteristics commonly observed in subsets with less severe RA.

Abstract: To define the clinical and immunologic pattern of expression of Sjögren syndrome (SS) associated with chronic hepatitis C virus (HCV) infection, we conducted a multicenter study aiming to collect a large number of patients with SS and HCV infection. Inclusion criteria were the fulfillment of at least 4 of the classification criteria for SS proposed by the European Community Study Group and repeated positive HCV serology, confirmed by recombinant immunoblot assay and/or detection of serum HCV-RNA by polymerase chain reaction. One hundred thirty-seven patients were included (104 female and 33 male; mean age, 65 yr). Seventy-nine (58%) patients presented a systemic process with diverse extraglandular manifestations, with articular involvement (44%), vasculitis (20%), and neuropathy (16%) being the most frequent features observed. The main immunologic features were antinuclear antibodies (65%), hypocomplementemia (51%), and cryoglobulinemia (50%). Cryoglobulins were associated with a higher frequency of cutaneous vasculitis, rheumatoid factor, and hypocomplementemia. Thirty-two (23%) patients had positive anti-Ro/SS-A and/or anti-La/SS-B antibodies; these patients were predominantly women and had a higher prevalence of some extraglandular features and a lower frequency of liver involvement. Nineteen (14%) patients developed neoplasia, with hematologic neoplasia (8 cases) and hepatocellular carcinoma (6 cases) being the most frequent types. Eighty-five percent of SS-HCV patients also fulfilled the recently proposed 2002 classification criteria for SS.In conclusion, HCV-associated SS is indistinguishable in most cases from the primary form using the most recent set of classification criteria. Chronic HCV infection should be considered an exclusion criterion for the classification of primary SS, not because it mimics primary SS, but because the virus may be implicated in the development of SS in a specific subset of patients. We propose the term "SS secondary to HCV" when these patients fulfill the 2002 classification criteria for SS.
