Abstract: OBJECTIVES: To update French Society for Rheumatology guidelines regarding the use of TNFalpha antagonists for treating patients with rheumatoid arthritis (RA). METHODS: Existing guidelines were updated using the AGREE instrument. Items that required updating were selected by a task force, the relevant literature was critically appraised, and new wording was suggested by a limited committee of experts then validated by the task force and subsequently by a panel of external reviewers. The three-topic structure of the recommendations (indication, initiation, and adjustment) and the final algorithm format were maintained. RESULTS: Of the 12 items, five were selected for updating; one pertained to the indication for treatment with TNFalpha antagonists, two to treatment initiation, and two to treatment adjustment. Of the four initially recommended criteria for determining that TNFalpha antagonist therapy is indicated, the first three were left unchanged (confirmed diagnosis of RA; active disease for more than 1month with objective evidence of inflammation or progressive structural damage, or dependency on glucocorticoid therapy, or progressive radiographic damage; and failure to respond adequately to methotrexate - or another agent when methotrexate is contraindicated - in the optimal tolerated dosage). The fourth and last criterion was modified as follows: co-morbidities should be evaluated in order to distinguish absolute contraindications from relative contraindications that require referral to a specialist. Of the four initial recommendations about TNFalpha antagonist initiation, the first and fourth were left unchanged (a workup should be performed prior to treatment initiation, and the patient should receive regular standardized follow-up); the second and third recommendations were modified as follows: there is no evidence that one TNFalpha antagonist is more effective than the others, and concomitant methotrexate therapy is generally advisable, regardless of the TNFalpha antagonist used. Of the four recommendations about treatment adjustment, the first two were modified as follows: the goal of treatment is to achieve the EULAR response criteria or better; and in non-responders, the dosage or dosing interval can be modified when infliximab is used, methotrexate should be added when the TNFalpha antagonist is used alone, and in all other situations the patient should be switched to a different TNFalpha antagonist. The other two recommendations about treatment adjustment were left unchanged (patients who fail to tolerate one TNFalpha antagonist can be switched to another TNFalpha antagonist if allowed by the nature of the adverse event; and when a remission is achieved, reduction or discontinuation of symptomatic drugs - most notably glucocorticoids - is appropriate, followed in the event of a prolonged remission by changes in the dosage and/or dosing interval of the TNFalpha antagonist or concomitant disease-modifying drug). CONCLUSION: These recommendations are designed to help practitioners optimize the use of TNFalpha antagonists in patients with RA seen in everyday practice. They do not constitute regulations.

Abstract: In chronic inflammatory diseases such as rheumatoid arthritis (RA), systemic inflammation appears as an independent risk factor, contributing to increased cardiovascular mortality. This high cardiovascular mortality reveals the existence of accelerated atherosclerosis, the pathogenesis of which may be associated with traditional risk factors such as smoking, hypertension, dyslipidemia, deterioration of insulin sensitivity, and less traditional risk factors such as hyperhomocysteinemia, inflammatory conditions and endothelial dysfunction. Control of systemic inflammation theoretically provides a means of preventing this higher cardiovascular mortality among RA patients. In this review we address the question of the impact of anti-rheumatic drugs currently used in RA, such as non-steroidal anti-inflammatory drugs (e.g. non-selective or cyclooxygenase-2 selective inhibitors), steroidal anti-inflammatory drugs (glucocorticoids), traditional disease-modifying anti-rheumatic drugs (e.g. methotrexate) or biologics (e.g. anti-tumour necrosis factor alpha anti-tumour necrosis factor alpha) on cardiovascular diseases in RA patients. We also discuss the specific mechanisms involved in the differential cardiovascular effects of these therapeutic agents.

Abstract: Primary immune deficiencies (PIDs) are characterized by functional and/or quantitative abnormalities of one or more immune system components. Several bone and joint abnormalities can occur in patients with PID, with arthritis being the most common. Joint manifestations, of which arthritis is the most common, occur chiefly in humoral PIDs (agammaglobulinemia, common variable immunodeficiency, hyper-IgM syndromes, and IgA deficiency) and occasionally in other PIDs (chronic granulomatous disease and Wiskott-Aldrich syndrome). Monoarthritis or oligoarthritis is the usual pattern, although polyarthritis may occur, occasionally with nodules suggesting rheumatoid arthritis. Arthritis in patients with PID is usually infectious in nature, the most common causative organism being Mycoplasma, followed by Staphylococcus, Streptococcus, and Haemophilus. These bacteria can induce not only synovial infections, but also aseptic arthritogenic inflammatory responses. Arthritis having no demonstrable relation to chronic infection has been reported also and ascribed to dysimmunity-driven mechanisms that exhibit a number of specific features. Bone lesions are far less common and usually due to infections complicating humoral PID. Distinctive bone manifestations occur in a number of rare PIDs (e.g., hyper-IgE syndrome and Di George syndrome) and in syndromes characterized by spondyloepiphyseal dysplasia. Familiarity with PID syndromes both enhances the diagnostic capabilities of physicians and provides insight into the pathophysiology of bone and joint abnormalities associated with immune dysfunction. In children and occasionally in adults, a combination of bone and/or joint manifestations and hypogammaglobulinemia may indicate PID. When there is no evidence of lymphoproliferative disease, infection, or iatrogenic complications, investigations for PID should be obtained. PID-related arthritis is a unique model for studying the pathogenesis of presumably postinfectious arthritis and of inflammatory joint diseases including rheumatoid arthritis.

Abstract: Infliximab is a chimeric monoclonal antibody against human tumour necrosis factor-alpha (TNF alpha), and has received marketing authorization for the treatment of both rheumatoid arthritis (RA) and Crohn's disease. The aim of the present survey was to assess retrospectively adverse drug reactions (ADRs) in patients treated with infliximab for RA in a rheumatology department of the Toulouse University Hospital (Rangueil Hospital). Among 32 patients included in 2000 and 2001, 43 "expected" ADRs occurred in 21 patients (65.6%) [mean age 51.4 +/- 14.0 years]. In four patients (12.5%), ADRs were classified as "serious". In five other patients, they required the discontinuation of infliximab. We identified mainly infectious (n = 21), allergic (n = 3) and cardiovascular (n = 3) ADRs. Infectious ADRs were as follows: seven urinary infections, with a positive rechallenge (R+) in five; nine respiratory infections, with R+ in five; and five cutaneous infections. An acute rise in blood pressure occurred in three patients who had already been treated with antihypertensive drugs. The incidence of ADRs was as follows: respiratory 28.0%; urinary 22.0%; cutaneous 15.6%; allergic 9.4%; and cardiovascular 9.4%. In conclusion, our data allowed a quantitative and qualitative assessment of infliximab-induced ADRs. Further studies are required in order to improve knowledge regarding ADRs induced by long-term treatment with infliximab.

Abstract: INTRODUCTION: The objectives of this study were to determine the predictive factors of long-term radiographic outcome of rheumatoid arthritis (RA) and to describe the relationship between joint damage and disability over the course of the disease. METHODS: A cohort of 191 patients with early RA referred from primary care physicians were prospectively followed for 10 years. To determine the predictive factors of radiographic outcome, univariate analysis of the relationship between baseline values and outcome measures was undertaken using a chi-squared or Fisher's exact test. Stepwise multiple logistic regression was also performed to select independent prognostic factors. RESULTS: From data available for 112 patients, univariate analysis revealed a total Sharp score at 10 years that was significantly correlated with erythrocyte sedimentation rate (ESR), presence and level of IgA rheumatoid factor, presence of an anti-citrullinated protein antibody (ACPA), serum level of matrix metalloproteinase-3 and radiographic score at baseline. Logistic regression identified the baseline erosion score to be the most important baseline parameter as an independent prognostic factor of total radiographic score at 10 years (odds ratio = 5.64; 95% confidence interval = 1.78 to 17.86). After excluding radiographic scores from the entry parameters, the presence of ACPA and ESR were also predictive of the final total Sharp score. The Health Assessment Questionnaire (HAQ) score was strongly correlated with disease activity parameters, such as disease activity score and pain, at baseline and at three, five and 10 years. No correlation was found between total radiographic Sharp score and HAQ score throughout the study. CONCLUSIONS: In this prospective study, baseline radiographic score, ESR and ACPA were the best predictive factors of 10-year radiographic outcome in early RA. HAQ disability was associated with disease activity throughout the 10-year follow-up but not with joint damage. This discrepancy with previous reports may be due in part to the early start of therapy with disease-modifying anti-rheumatic drugs.

Abstract: OBJECTIVE: To analyse the safety of leflunomide plus infliximab combination therapy, in adult rheumatoid arthritis (RA) patients. PATIENTS: A retrospective study of 17 adult patients with active RA (DAS 28 = 5.94 +/- 0.88 at baseline) who were treated with a combination of leflunomide plus infliximab after failure of treatment with other DMARDs. 13 patients were treated for a minimum of 3 months with leflunomide without toxicity before beginning infliximab. Treatment was begun simultaneously with both drugs in 4 patients. Side effects (clinical and biological) and efficacy (DAS 28) were evaluated at each infliximab infusion (3 mg/kg at week 0, 2, 6 and then every 8 weeks). RESULTS: Thirteen patients experienced 20 types of side effects and 8 of them stopped the combination therapy. The causes of discontinuation were congestive heart failure (1 case), hypertension with thoracic pain (2 cases), eczematous skin patches (2 cases) and neutropenia (3 cases). No death was registered. Nine RA patients continuted the therapy with a median follow-up of 22 weeks. Only 4 of them experienced no side effects. Eight patients were positive for antinuclear antibodies (ANA) and 1 for double-stranded DNA (dsDNA) antibodies at study entry. After treatment, 13 and 5 patients tested positive respectively for ANAs and dsDNA antibodies. There was no relationship between discontinuation and ANA/dsDNA positivity. CONCLUSION: In this cohort, adverse events were not very different from those seen in patients on either treatment alone and the combination of leflunomide plus infliximab did not appear to be as badly tolerated as described in a previous study.

Abstract: OBJECTIVE: To evaluate whether early combined therapy with methotrexate (MTX) and sulfasalazine (SSZ) during the first year in early rheumatoid arthritis (RA) induces long term beneficial effects, compared with monotherapy, when the further treatment strategy is a free choice. METHODS: Study design: five year multicentre prospective longitudinal trial. Participants: 146/205 patients with RA previously included in a one year prospective randomised trial comparing the effects of treatment with MTX, SSZ, or a combination of both. Criteria for inclusion: patients with early RA (< or =1 year duration). Follow up: between the end of years 1 and 5, patients were followed up and treated by their own rheumatologist, who was allowed to indicate any treatment. Outcome measures: disease activity score (DAS), health assessment questionnaire (HAQ), and Sharp/van der Heijde radiological score at baseline and after five years of follow up. Analysis: comparison of the five year follow up DAS, HAQ, and radiological scores in patients given combined and single treatment during the first year. RESULTS: At the end of the five years of follow up, the patients primarily receiving single or combined treatment had similar mean DAS, HAQ, and radiographic scores. CONCLUSION: Treatment of patients with early RA using combined therapy with MTX and SSZ during the first year did not influence the long term inflammatory status, or disability, or structural changes, compared with single disease modifying antirheumatic drug treatment.

Abstract: OBJECTIVES: To investigate the potential clinical benefit of a combination therapy. METHODS: 205 patients fulfilling the ACR criteria for rheumatoid arthritis (RA), not treated with disease modifying antirheumatoid drugs previously, with an early (< or = 1 year duration), active (Disease Activity Score (DAS) > 3.0), rheumatoid factor and/or HLA DR 1/4 positive disease were randomised between sulphasalazine (SASP) 2000 (maximum 3000) mg daily (n = 68), or methotrexate (MTX) 7.5 (maximum 15) mg weekly (n = 69) or the combination (SASP + MTX) of both (n = 68). RESULTS: The mean changes in the DAS during the one year follow up of the study was -1.15, -0.87, -1.26 in the SASP, MTX, and SASP + MTX group respectively (p = 0.019). However, there was no statistically significant difference in terms of either EULAR good responders 34%, 38%, 38% or ACR criteria responders 59%, 59%, 65% in the SASP, MTX, and SASP + MTX group respectively. Radiological progression evaluated by the modified Sharp score was very modest in the three groups: mean changes in erosion score: +2.4, +2.4, +1.9, in narrowing score: +2.3, +2.1, +1.6 and in total damage score: +4.6, +4.5, +3.5, in the SASP, MTX, and SASP + MTX groups respectively. Adverse events occurred more frequently in the SASP + MTX group 91% versus 75% in the SASP and MTX group (p = 0.025). Nausea was the most frequent side effect: 32%, 23%, 49% in the SASP, MTX, and SASP + MTX groups respectively (p = 0.007). CONCLUSION: This study suggests that an early initiation therapy of disease modifying drug seems to be of benefit. However, this study was unable to demonstrate a clinically relevant superiority of the combination therapy although several outcomes were in favour of this observation. The tolerability of the three treatment modalities seems acceptable.

Abstract: OBJECTIVES: The phase III RADIATE study examined the efficacy and safety of tocilizumab, an anti-IL-6 receptor monoclonal antibody in patients with rheumatoid arthritis (RA) refractory to tumour necrosis factor (TNF) antagonist therapy. METHODS: 499 patients with inadequate response to one or more TNF antagonists were randomly assigned to receive 8 mg/kg or 4 mg/kg tocilizumab or placebo (control) intravenously every 4 weeks with stable methotrexate for 24 weeks. ACR20 responses, secondary efficacy and safety endpoints were assessed. RESULTS: ACR20 was achieved at 24 weeks by 50.0%, 30.4% and 10.1% of patients in the 8 mg/kg, 4 mg/kg and control groups, respectively (less than p<0.001 both tocilizumab groups versus control). At week 4 more patients achieved ACR20 in 8 mg/kg tocilizumab versus controls (less than p = 0.001). Patients responded regardless of most recently failed anti-TNF or the number of failed treatments. DAS28 remission (DAS28 <2.6) rates at week 24 were clearly dose related, being achieved by 30.1%, 7.6% and 1.6% of 8 mg/kg, 4 mg/kg and control groups (less than p = 0.001 for 8 mg/kg and p = 0.053 for 4 mg/kg versus control). Most adverse events were mild or moderate with overall incidences of 84.0%, 87.1% and 80.6%, respectively. The most common adverse events with higher incidence in tocilizumab groups were infections, gastrointestinal symptoms, rash and headache. The incidence of serious adverse events was higher in controls (11.3%) than in the 8 mg/kg (6.3%) and 4 mg/kg (7.4%) groups. CONCLUSION: Tocilizumab plus methotrexate is effective in achieving rapid and sustained improvements in signs and symptoms of RA in patients with inadequate response to TNF antagonists and has a manageable safety profile.

Abstract: INTRODUCTION: Rheumatoid arthritis (RA) is a complex polygenic disease of unknown etiology. HLA-DRB1 alleles encoding the shared epitope (SE) (RAA amino acid pattern in positions 72 to 74 of the third hypervariable region of the DRbeta1 chain) are associated with RA susceptibility. A new classification of HLA-DRB1 SE alleles has been developed by Tezenas du Montcel and colleagues to refine the association between HLA-DRB1 and RA. In the present study, we used RA samples collected worldwide to investigate the relevance of this new HLA-DRB1 classification in terms of RA susceptibility across various Caucasoid and non-Caucasoid patients. METHODS: Eighteen subsamples were defined from a total number of 759 cases and 789 controls and grouped in 10 samples on the basis of their ethnic origin. HLA-DRB1 alleles were divided into five groups (S1, S2, S3D, S3P, and X) according to the new HLA-DRB1 allele classification. The whole analysis was performed by comparing carrier frequencies for the five HLA-DRB1 allele groups between RA patients and controls across the 10 Caucasoid and non-Caucasoid samples. The Mantel-Haenszel method of meta-analysis provided a global odds ratio (OR) estimate with 95% confidence interval (CI). RESULTS: A positive association with RA susceptibility was found for S2 allele carriers (OR 2.15, 95% CI 1.54 to 3.00; p < 10(-5)) and S3P allele carriers (OR 2.74, 95% CI 2.01 to 3.74; p < 10(-5)). A negative association was found for S1 alleles (OR 0.60, 95% CI 0.48 to 0.76; p < 10(-4)) and X alleles (OR 0.58, 95% CI 0.39 to 0.84; p = 4 x 10(-3)). No significant association was highlighted for the S3D group of alleles (OR 0.89, 95% CI 0.69 to 1.14; p = 0.89). The complementary genotype analysis fit with the genotype risk hierarchy previously reported in Caucasoid RA patients. CONCLUSION: So far, the present study is the first attempt to investigate the relevance of this new HLA-DRB1 classification in terms of RA susceptibility on both Caucasoid and non-Caucasoid samples. Our results support the hypothesis of a differential role played by different HLA-DRB1 allele groups in RA susceptibility across different ethnic backgrounds and confirm the interest of such an HLA-DRB1 classification in differentiating predisposing and protective alleles.

Abstract: OBJECTIVE: The Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes (TEMPO) is a 3-year, double-blind, multicenter study evaluating the efficacy and safety of etanercept, methotrexate, and the combination of etanercept plus methotrexate in patients with active rheumatoid arthritis (RA). The results after 1 and 2 years of the study have been previously reported. Here we provide the 3-year clinical and radiographic outcomes and safety of etanercept, methotrexate, and the combination in patients with RA. METHODS: In this randomized, double-blind, multicenter TEMPO study, 682 patients received etanercept 25 mg twice weekly, methotrexate < or =20 mg weekly, or the combination. Key efficacy assessments included the Disease Activity Score (DAS) and the DAS in 28 joints. RESULTS: Combination therapy resulted in significantly greater improvement in the DAS and in more patients with disease in remission than either monotherapy. This finding was confirmed by longitudinal analysis; patients receiving combination therapy were more than twice as likely to have disease in remission than those receiving either monotherapy. Independent predictors of remission included male sex, lower disease activity, lower level of joint destruction, and/or better physical function. Combination and etanercept therapy both resulted in significantly less radiographic progression than did methotrexate (P < 0.05). Etanercept and combination treatment were well tolerated, with no new safety findings. CONCLUSION: Etanercept plus methotrexate showed sustained efficacy through 3 years and remained more effective than either monotherapy, even after adjustment for patient withdrawal. Combination therapy for 3 years led to disease remission and inhibition of radiographic progression, 2 key goals for treatment of patients with RA.

Abstract: OBJECTIVES: The French Society of Rheumatology initiated a large national multicenter, longitudinal and prospective cohort, the so-called "ESPOIR cohort study" in order to set up databases to allow various investigations on diagnosis, prognostic markers, epidemiology, pathogenesis and medico-economic factors in the field of early arthritis and rheumatoid arthritis. METHODS: Patients were recruited if they had undifferentiated arthritis or rheumatoid arthritis, of less than 6 months disease duration and if they were DMARD and steroids naïve. Patients have then to be followed every 6 months during the first 2 years then every year during at least 10 years. Clinical, biological, radiographic and medico-economic databases have been constituted to fit in the different objectives of the project and more than 20 scientific studies have already been accepted by the scientific committee. RESULTS: 813 patients were included (76.75% were female). The mean age was 48.07+/-12.55 years. The mean delay from the onset of symptoms to referral to the rheumatologist was 74.8+/-76.6 days. Baseline swollen and tender joint counts were 7.19+/-5.37 and 8.43+/-7.01; DAS28 score was 5.11+/-1.31. CRP was abnormal in 38.9% of the patients; 44.2%, 45.8% and 38.8% had respectively IgM rheumatoid factor (RF), IgA RF and anti-CCP antibodies. HLA DRB1*01 or 04 genes were found in 56.7% of them. Finally, 22% of these patients had erosions on hand or feet at baseline.

Abstract: In chronic inflammatory diseases, such as rheumatoid arthritis, inflammation acts as an independent cardiovascular risk factor and the use of anti-inflammatory drugs, such as anti-tumor necrosis factor alpha (anti-TNFalpha), may decrease this risk. The phagocytosis of oxidized low density lipoproteins (LDLs) accumulated in the subendothelium by mononuclear cells influences atherosclerosis and depends on CD36 expression. We investigated the role of TNFalpha and adalimumab, a human anti-TNFalpha monoclonal antibody widely used in human pathology, in CD36 expression in human monocytes. Human monocytes were prepared by adherence from whole-blood buffy-coat fractions from healthy donors. CD36 expression was assessed by RT-PCR and flow cytometry, with various TNFalpha or adalimumab concentrations. Implication of peroxisome proliferator-activated receptor (PPAR)gamma in the regulation of CD36 expression was assessed using specific inhibitor or gel shift assays. The impact of redox signaling was investigated using quantification of reactive oxygen species, antioxidant and a NADPH oxidase inhibitor. The F(ab')2 fragment of adalimumab was isolated and its effect was analyzed. TNFalpha inhibits both CD36 membrane expression and mRNA expression. This inhibition involves a reduction in PPARgamma activation. In contrast, adalimumab increases both CD36 membrane expression and mRNA expression. This induction is independent of the Fc portion of adalimumab and involves redox signaling via NADPH oxidase activation. CD36 expression on human monocytes is inhibited by TNFalpha and independently increased by adalimumab. These data highlight that pro-inflammatory cytokines and their specific neutralization influence the expression of cellular receptors implicated in atherosclerosis. Further studies are needed to investigate the clinical implications of these results in accelerated atherosclerosis observed in rheumatoid arthritis.

Abstract: The HLA-DRB1 gene was reported to be associated with anticitrullinated protein/peptide autoantibody (ACPA) production in rheumatoid arthritis (RA) patients. A new classification of HLA-DRB1 alleles, reshaping the shared epitope (SE) hypothesis, was recently found relevant in terms of RA susceptibility and structural severity. We investigated the relevance of this new classification of HLA-DRB1 SE+ alleles in terms of rheumatoid factor (RF) and ACPA production in a sample of French RA patients. We studied 160 early RA patients included in a prospective longitudinal cohort of French Caucasian patients with recent-onset arthritis. RF, anticyclic citrullinated peptide 2 (anti-CCP2) and antideiminated human fibrinogen autoantibodies (AhFibA) were assessed in all patients at inclusion. The HLA-DRB1 gene was typed by PCR-sequence specific oligonucleotides probes (PCR-SSOP), and SE+ alleles were classified into four groups (S1, S2, S3P, S3D) according to the new classification. The new classification of HLA-DRB1 SE+ alleles distinguishes predisposing and protective alleles for RF, anti-CCP2 or AhFibA production. The presence of S2 or S3P alleles is associated with both RF, anti-CCP2 or AhFibA positivity, whereas the presence of S3D or S1 alleles appears to be protective for RF, anti-CCP2 or AhFibA positivity. The new classification of HLA-DRB1 SE+ alleles is relevant in terms of autoantibody production in early RA patients by differentiating predisposing and protective alleles for RF or ACPA production.

Abstract: BACKGROUND: The objective was to develop a clinical practice format for choosing a second-line disease-modifying anti-rheumatic drug (DMARD) after a 6-month course of a first-line DMARD in patients with early RA. METHODS: A panel of 34 experts selected treatment option from various scenarios using the Thurstone pairwise method. The experts had to choose between two proposed DMARDs without proposing other options. The scenarios were obtained using the three items: DAS28, rheumatoid factor status and radiographic structural damage. A sample of 240 among 480 scenarios for each expert was taken at random. Responses given by at least 20% of the experts were considered pertinent. RESULTS: Recommendations for choosing a second DMARD for early RA after failure of a 6-month course of a first-line DMARD were established according to 4 parameters: type of first-line DMARD, activity, RF status and radiographic joint damage. The results of this study suggest that in patients with early RA who fail a 6-month course of first-line DMARD therapy, the best options may be addition of corticosteroid when disease activity is moderate to high and switching to a biologic agent when further radiographic joint damage occurs, particularly in patients with positive tests for RF. CONCLUSION: Although our scenarios did not include step-up (add instead of substitute) strategies, except for corticosteroids, we feel that the format presented here can optimise the management of patients with early RA seen in clinical practice.

Abstract: OBJECTIVE: To determine geographical variation in the prevalence of rheumatoid arthritis (RA) and spondyloarthropathies (SpA) in France. METHODS: The survey sample was drawn from 7 areas of France. Households were randomly selected using the national telephone directory, and an individual within each household was randomly chosen by the next-birthday method. All cases of suspected RA and SpA were confirmed by the patient's rheumatologist or by clinical examination. Standardized estimates of prevalence were compared between regions and groups of regions. RESULTS: In total 15,219 anonymous telephone numbers were selected. An average response rate of 64% led to a total of 9395 respondents included in the study. The highest regional rates of RA were observed in the south (range 0.59-0.66%), and the lowest in the north (range 0.14-0.24%), with a national rate of 0.31% (95% CI 0.18-0.48%). Regional heterogeneity was observed for SpA, with the highest rates in Bretagne (0.47%) and the Sud-Est (0.53%) and a national rate of 0.30% (95% CI 0.17-0.46%). CONCLUSION: This study is the largest of its kind conducted in France. It shows inter-regional variations, mainly in RA, with a higher prevalence in the south of the country. The many potential reasons for the heterogeneity observed, including genetic and environmental factors, warrant further research.

Abstract: Within the major histocompatibility complex (MHC), the human leucocyte antigen (HLA)-DRB1 locus is clearly associated with rheumatoid arthritis (RA). Using a microsatellite (MSat) typing approach, we aimed to identify other loci associated with RA susceptibility and/or severity within the MHC. A panel of nine MSat HLA loci [D6S291, D6S2876 (G51152), D6S1666 (DQCAR II), D6S273, D6S2789 (TNFd), D6S2810 (MIB), D6S265, D6S2222, D6S2239], and HLA-A, -B and -DRB1 genes were typed in 170 RA cases and 282 controls. For susceptibility analysis, MSat and HLA allele distribution were compared between cases and controls, before and after stratification on HLA-DRB1*04. Haplotype frequencies were estimated using an expectation-maximization algorithm in a permutation test procedure. For severity analysis, we compared the distribution of structural damage score at onset and after 4 years of follow-up in RA cases carrying susceptibility alleles. Two MSat polymorphisms were positively associated with RA susceptibility: allele*136 of D6S265 [odds ratio, OR (confidence interval, CI) = 1.55 (1.11-2.17), P= 0.007], allele*116 of D6S2239 [OR = 1.34 (1-1.79), P= 0.03] and HLA-A2 [OR = 1.46 (1.08-1.98), P= 0.01]. Two MSat polymorphisms were negatively associated with RA susceptibility: allele*133 of D6S273 [OR = 0.3 (0.1-0.75), P= 0.005] and allele*177 of D6S291 [OR = 0.72 (0.53-0.96), P= 0.02]. The association between allele*136 of D6S265 and RA susceptibility remained unchanged after stratification on HLA-DRB1*04. The haplotypic analysis showed an overrepresentation of D6S265*136/HLA-A*02 haplotype, which suggests an effect independent of HLA-DRB1 locus in RA susceptibility. While HLA-A2 and HLA-DR4 were associated with RA severity, no MSat polymorphism was associated with structural damage score.

Abstract: OBJECTIVE: To assess the radiological damage progression in patients with recent rheumatoid arthritis in sustained remission. METHODS: A cohort of 191 patients with active early (<1 year) rheumatoid arthritis was prospectively assessed at baseline, 3 and 5 years by the Disease Activity Score (DAS) and the Sharp-van der Heijde Score (SHS) for radiographic damage. Patients in remission (DAS<1.6) at the 3-year and 5-year time points were compared with patients with a persistently active rheumatoid arthritis by Wilcoxon's signed rank test. RESULTS: 57 patients died, were lost to follow-up or had incomplete data; 30 (15.7% of those who completed) patients were in remission at 3 and 5 years. The SHS in these two groups was not significantly different at baseline (p = 0.15), but was lower in the remission group at 5 years (p = 0.0047). The median (IQR) radiographic score increased from 0.5 (0-7) at baseline to 2.5 (0-14) after 5 years for the remission group (p = 0.18) and from 2 (0-7) to 13 (3-29) in the group with active rheumatoid arthritis (p<0.001). 5 (16.7%) patients in remission had relevant progression of radiographic damage (ie, progression >4.1 points) and 6 (20%) presented new erosions in a previously unaffected joint between the third and the fifth years. CONCLUSION: Patients with early rheumatoid arthritis in sustained remission did not present statistically significant radiographic degradation at the group level; nevertheless, 16.7% of these patients did present degradation. Absence of progression should be part of the remission definition in rheumatoid arthritis.

Abstract: OBJECTIVE: To evaluate and determine prognostic factors of 5-year quality of life in patients with early rheumatoid arthritis (RA). METHODS: A cohort of 191 patients with RA and disease duration < 1 year was prospectively followed over 5 years. The outcome measure was quality of life as assessed by the Arthritis Impact Measurement Scales 2 (AIMS2). Univariate analysis, then stepwise multiple logistic regression, was used to find independent baseline prognostic variables. RESULTS: After accounting for death, loss of followup, and missing data, 158 patients (82.72%) were included in the analysis. The mean AIMS2 physical, symptom, psychological, social interaction, and work scores after 5 years were 1.6 (range 0-6.88), 4.0 (0-10), 3.48 (0-9.22), 4.06 (0-8.69), and 1.87 (0-8.13), respectively. The AIMS2 physical component was significantly correlated with Health Assessment Questionnaire (HAQ) score at 5 years. Logistic regression analysis revealed that the baseline values able to predict the 5-year physical, psychological, symptom, social interaction, and work status were, respectively: HAQ score and erythrocyte sedimentation rate (ESR), body mass index (BMI), HAQ; erosion score and sex, HAQ; ESR and anti-perinuclear antibody; matrix metalloproteinase-3 (MMP3) level, joint space narrowing, and tender joint scores; HAQ score and age. CONCLUSION: The multidimensional structure of the AIMS2 allowed us to assess the 5-year health-related quality of life in early RA. Using this instrument as an outcome variable, prognostic factors were selected and varied widely depending on the evaluated domain. The baseline HAQ score was the best predictive factor of 4 of the 5 domains of the AIMS2.

Abstract: OBJECTIVES: To develop recommendations for TNFalpha-antagonist therapy in patients with rheumatoid arthritis (RA) seen in everyday practice, under the aegis of the French Society for Rheumatology. METHOD: We used the methods recommended by the French Agency for Healthcare Accreditation and Evaluation, the AGREE collaboration, and the European League against Rheumatism (EULAR). The recommendations focus on patient selection, monitoring, and treatment adjustments. RESULTS: Criteria for selecting patients eligible for TNFalpha-antagonist treatment of RA include: 1) a definitive diagnosis of RA; 2) disease activity for longer than 1 month, including presence of objective signs of inflammation; or radiographic progression; 3) previous failure of methotrexate in the highest tolerated dosage or of another disease-modifying antirheumatic drug in patients with contraindications to methotrexate; 4) absence of contraindications to TNFalpha-antagonist therapy. When starting TNFalpha-antagonist therapy 1) a thorough baseline evaluation should be conducted; 2) any of the three available agents can be used, as no differences in efficacy have been identified in patient populations; 3) concomitant methotrexate therapy is recommended regardless of the TNFalpha antagonist used; and 4) patients should receive standardized follow-up at regular intervals. Treatment adjustments should be based on the following: 1) the treatment objective is achievement of a EULAR response; 2) when such a response is not achieved, the dosage or dosing interval can be changed, or the patient can be switched to another TNFalpha antagonist; 3) in patients who experience intolerance to a TNFalpha antagonist, another TNFalpha antagonist may be tried, depending on the nature of the adverse event; 4) occurrence of a remission should lead to a reduction in symptomatic medications, most notably glucocorticoids where used; in the event of a prolonged remission, either the TNFalpha antagonist or the concomitant disease-modifying antirheumatic drug may be reduced. CONCLUSION: These recommendations are intended to help physicians use TNFalpha antagonists in their everyday practice with RA patients. They do not constitute regulations.

Abstract: OBJECTIVE: To develop clinical practice guidelines for the evaluation and management of cardiovascular risk in patients with rheumatoid arthritis (RA), using the evidence-based approach and expert opinion. METHODS: Recommendations were developed using the evidence-based approach and expert opinion: A scientific committee used a Delphi procedure to select five questions, which formed the basis for developing the recommendations; Evidence providing answers to the five questions was sought in the literature; Based on this evidence, recommendations were developed by a panel of experts. RESULTS: The recommendations were as follows: 1) In patients with RA, attention should be given to the risk of cardiovascular disease, which is responsible for an excess burden of morbidity and mortality; 2) It must be recognized that RA may be an independent cardiovascular risk factor. Persistent inflammation is an additional risk factor; 3) The cardiovascular risk should be evaluated, and modifiable risk factors should be corrected; 4) In patients with RA requiring glucocorticoid therapy, the need for cardiovascular risk minimization is among the reasons that mandate the use of the minimal effective dose; 5) It should be recognized that methotrexate may protect against cardiovascular mortality in patients with RA; 6) It should be recognized that TNFalpha antagonists remain contraindicated in patients with RA and severe heart failure. TNFalpha antagonists do not seem to worsen moderate heart failure and may protect against cardiovascular mortality; 7) AFSSAPS recommendations about LDL-cholesterol objectives should be followed, with active RA being counted as a cardiovascular risk factor; 8) In patients with RA, statin therapy should be considered only when cholesterol levels are elevated despite appropriate dietary treatment; 9) RA per se does not indicate aspirin for primary prevention. When aspirin is used for secondary prevention, it should be recognized that concomitant treatment with nonsteroidal antiinflammatory drugs (NSAIDs) may decrease the antiplatelet effects and increase the gastrointestinal side effects of aspirin therapy.

Abstract: OBJECTIVE: To investigate the safety of infliximab (INF) combination therapy with leflunomide (LEF) or azathioprine (AZA) in patients with rheumatoid arthritis (RA). METHOD: A standardized questionnaire on the use of INF in combination with LEF or AZA was mailed to hospital physicians and collected over a 2 month period. Adverse events (AE) and the reasons for withdrawal of combination therapy were analyzed. RESULTS: Data on 225 patients with RA were collected retrospectively. INF was used in combination with LEF in 171 patients and with AZA in 54. The duration of INF exposure was similar in both groups (mean 8.8 mo). AE were reported in 75 patients (33.3%), 60 LEF/INF (35%) and 15 AZA/INF combinations (27.8%) (p=nonsignificant). No unexpected AE were observed. The main AE were infections (6.2%), cytopenia (5.8%), hepatotoxicity (5.8%), reactions to infusion (5.3%), and skin reactions (4%). At the time the questionnaires were sent out, 161 patients were continuing combination therapies. The main reasons for drug withdrawal were AE (53 patients, 23.5%), inefficacy (10 patients, 4%), and one temporary discontinuation for surgery. CONCLUSION: Our study suggests that INF used in combination with LEF or AZA could be an alternative to methotrexate/INF combinations.

Abstract: OBJECTIVE: To develop clinical practice guidelines for the use of nonpharmacological treatments in patients with early rheumatoid arthritis (RA), using the evidence-based approach and expert opinion. METHODS: A scientific committee used a Delphi prioritization procedure to select five questions. Evidence providing answers to the five questions was sought in the literature and presented to a panel of rheumatologists. The panel developed five detailed recommendations, filling gaps in evidence with their expert opinion. The strength of each recommendation was determined. RESULTS: Of the 565 publications retrieved by the literature review, 198 were included in the analysis. The five recommendations on nonpharmacological treatments for early RA were validated by a final vote among all participants. The recommendations are as follows: (1) physicians may decide to provide joint protection education to patients with potentially severe early RA, with the knowledge that structured joint protection programs have not been found effective; (2) physical exercise and sports can be recommended to patients with early RA; muscle strength exercises are advisable; (3) in patients with early RA, metatarsal pain and/or foot alignment abnormalities should be looked for regularly, and appropriate insoles should be prescribed if needed; (4) dietary measures and nutritional supplements are not indicated as part of the treatment of early RA; (5) elimination diets, particularly those with low intakes of dairy products, should be discouraged in patients with early RA. CONCLUSION: These recommendations should help to improve practice uniformity and, ultimately, to improve the management of RA.

Abstract: OBJECTIVES: To develop clinical practice guidelines for the use of methotrexate in rheumatoid arthritis (RA), using the evidence-based approach and expert opinion. METHODS: A scientific committee used a Delphi procedure to select five questions, which formed the basis for developing recommendations. Evidence providing answers to the five questions was sought in the Cochrane databases, PubMed, and proceedings of meetings of the French Society for Rheumatology, European League Against Rheumatism, and American College of Rheumatology. Using this evidence, a group of rheumatologists developed and validated the recommendations. For each recommendation, the level of evidence and the extent of agreement among experts were specified. RESULTS: The recommendations were as follows: 1: The starting dosage for methotrexate in patients with RA should not be less than 10 mg/week and should be determined based on disease severity and patient-related factors; 2: When a patient with RA shows an inadequate response to methotrexate, the dosage should be increased at intervals of 6 weeks, up to 20 mg/week, according to tolerance and patient-related factors; 3: When starting methotrexate treatment in a patient with RA, preference should be given to the oral route. A switch to the intramuscular or subcutaneous route should be considered in patients with poor compliance, inadequate effectiveness, or gastrointestinal side effects; 4: At present, there is no evidence indicating that a change in methotrexate dosage is in order when a TNF antagonist is given concomitantly; 5: The investigations that are mandatory before starting methotrexate therapy in a patient with RA consist of a full blood cell count, serum transaminase levels, serum creatinine with computation of creatinine clearance, and a chest radiograph. In addition, serological tests for the hepatitis viruses B and C and a serum albumin assay are recommended. In patients with a history of respiratory disease or current respiratory symptoms, lung function tests with determination of the diffusing capacity for carbon monoxide are recommended; 6: Investigations that are mandatory for monitoring methotrexate therapy in patients with RA consist of full blood cell counts and serum transaminase and creatinine assays. These tests should be obtained at least once a month for the first 3 months then every 4-12 weeks; 7: Folate supplementation can be given routinely to patients treated with methotrexate for RA. In practice, a minimal dosage of 5 mg of folic acid once a week, at a distance from the methotrexate dose, is appropriate; 8: In the event of respiratory symptoms possibly related to methotrexate toxicity, the drug must be stopped and symptom severity evaluated. Should evidence of serious disease be found, the patient should be admitted immediately or advice from a pulmonologist should be obtained immediately. CONCLUSION: Recommendations about methotrexate therapy for RA were developed. These recommendations should help to improve practice uniformity and, ultimately, to improve the management of RA.
