Clinical practice format for choosing a second-line disease modifying anti-rheumatic drug in early rheumatoid arthritis after failure of 6 months' first-line DMARD therapy.

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.

Health assessment questionnaire score is the best predictor of 5-year quality of life in early rheumatoid arthritis.

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.

TNFalpha antagonist therapy in ankylosing spondylitis and psoriatic arthritis: recommendations of the French Society for Rheumatology.

OBJECTIVES: To develop recommendations for TNFalpha antagonist therapy in patients with spondyloarthropathies. METHODS: The Delphi consensus procedure was used to select questions, to which evidence-based answers were sought in the literature. Expert opinion was used when needed to estimate the risks and benefits of TNFalpha antagonists. TNFalpha antagonists exert potent antiinflammatory effects but fail to provide a definitive cure. RESULTS: Recommendations were developed for patients with ankylosing spondylitis (AS) or psoriatic arthritis (PsA). The following criteria for TNFalpha antagonist therapy were selected: definitive diagnosis of AS or PsA, active disease for at least 4 consecutive weeks documented during two physician visits, overall physician's assessment of disease activity>/=4/10 and BASDAI>/=4/10 in axial disease or at least three tender and swollen joints in peripheral disease, failure to respond adequately to at least three nonsteroidal antiinflammatory drugs given in optimal dosages for at least 3 months in axial disease or at least one disease-modifying antirheumatic drug (methotrexate, leflunomide, sulfasalazine) for at least 4 months, with local glucocorticoid injections if appropriate, in peripheral disease. Effectiveness and safety should be evaluated by a rheumatologist. The frequency of monitoring depends on the drug. Lack of effectiveness should be defined as inadequate improvement after 6-12 weeks, with a less than two-point decrease in the BASDAI in axial disease or a less than 30% decrease in the tender and swollen joint counts in peripheral disease. CONCLUSION: These clinical practice recommendations should help rheumatologists in their everyday decisions regarding the use of TNFalpha antagonist therapy in patients with AS or PsA.

Recommendations of the French Society for Rheumatology. TNFalpha antagonist therapy in rheumatoid arthritis.

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.

Cardiovascular risk and rheumatoid arthritis: clinical practice guidelines based on published evidence and expert opinion.

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.

Methotrexate therapy for rheumatoid arthritis: clinical practice guidelines based on published evidence and expert opinion.

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.

Nonpharmacological treatments in early rheumatoid arthritis: clinical practice guidelines based on published evidence and expert opinion.

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.

Serial determination of cyclic citrullinated peptide autoantibodies predicted five-year radiological outcomes in a prospective cohort of patients with early rheumatoid arthritis.

The objective of this study was to evaluate the potential of serially determined anti-cyclic citrullinated peptide (CCP) antibodies for predicting structural joint damage in patients with early rheumatoid arthritis (RA), compared to a single baseline determination. Ninety-nine RA patients with disease durations of less than one year and no history of disease-modifying antirheumatic drug therapy were followed prospectively for at least five years. Anti-CCP2 concentrations were measured using a second-generation ELISA. Sharp scores as modified by van der Heijde were determined on hand and foot radiographs. Anti-CCP2 antibodies were detected in 55.5% of patients at baseline and 63.6% at any time during the first three years. Presence of anti-CCP2 at any time during the first three years was associated with radiographic damage at baseline (odds ratio (OR), 3.66; 95% confidence interval (95% CI) 0.99-13.54) and with five year progression of the total Sharp score (OR, 3.17; 95% CI, 1.3-7.7), erosion score (OR, 5.3; 95% CI, 1.4-19.2) and joint space narrowing score (OR, 2.8; 95% CI, 1.15-6.8). The presence of anti-CCP2 or IgM RF at baseline did not predict these outcomes. Patients with negative anti-CCP2 tests throughout follow-up had less radiographic progression than patients with increasing anti-CCP2 concentrations; they did not differ from patients with decreasing anti-CCP2 antibody levels. HLADRB1* typing showed that progression of the mean modified Sharp score was not correlated with the presence of the shared epitope alleles. In conclusion, serially determined anti-CCP2 antibodies during the first three years of follow-up performs better than baseline determination for predicting radiographic progression in patients with early RA.

Safety of infliximab used in combination with leflunomide or azathioprine in daily clinical practice.

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.

The rheumatoid shoulder: current consensus on diagnosis and treatment.

Shoulder involvement is usually inconspicuous in patients with rheumatoid arthritis, and the clinical manifestations are nonspecific. Nevertheless, shoulder involvement should be sought routinely and detected early. Range of motion at the shoulder should be evaluated. Although normal radiographic findings do not rule out shoulder involvement, radiographs are crucial for detecting micro- and macro-geodes during follow-up. The development of glenohumeral joint space narrowing is a turning point that indicates a risk of rapid joint destruction. Magnetic resonance imaging is useful for assessing the lesions and guiding the treatment strategy. Stepwise use of local interventions as indicated by imaging findings is recommended. Joint replacement should not be left too late, and surgical procedures on the shoulder should be built into the overall treatment plan.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces rheumatoid arthritis synovial fibroblast proliferation through mitogen-activated protein kinases and phosphatidylinositol 3-kinase/Akt.

A hallmark of rheumatoid arthritis (RA) is the pseudo-tumoral expansion of fibroblast-like synoviocytes (FLSs), and the RA FLS has therefore been proposed as a therapeutic target. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) has been described as a pro-apoptotic factor on RA FLSs and, therefore, suggested as a potential drug. Here we report that exposure to TRAIL-induced apoptosis in a portion (up to 30%) of RA FLSs within the first 24 h. In the cells that survived, TRAIL induced RA FLS proliferation in a dose-dependent manner, with maximal proliferation observed at 0.25 nm. This was blocked by a neutralizing anti-TRAIL antibody. RA FLSs were found to express constitutively TRAIL receptors 1 and 2 (TRAIL-R1 and TRAIL-R2) on the cell surface. TRAIL-R2 appears to be the main mediator of TRAIL-induced stimulation, as RA FLS proliferation induced by an agonistic anti-TRAIL-R2 antibody was comparable with that induced by TRAIL. TRAIL activated the mitogen-activated protein kinases ERK and p38, as well as the phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway with kinetics similar to those of TNF-alpha. Moreover, TRAIL-induced RA FLS proliferation was inhibited by the protein kinase inhibitors PD98059, SB203580, and LY294002, confirming the involvement of the ERK, p38, and PI3 kinase/Akt signaling pathways. This dual functionality of TRAIL in stimulating apoptosis and proliferation has important implications for its use in the treatment of RA.

Role and modalities of information and education in the management of patients with rheumatoid arthritis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVES: To develop recommendations for the information and education of patients with rheumatoid arthritis (RA) seen in everyday practice, using evidence from the literature, supplemented with expert opinion when needed. METHODS: A scientific committee developed eight questions using the Delphi consensus procedure. A task force reviewed the literature for answers to these questions, using the PubMed Medline database (1980-2004) and the 2002-2004 databases of the annual meetings held by the French Society for Rheumatology (SFR), the European League Against Rheumatism (EULAR), and the American College of Rheumatology (ACR); the indexing terms for the search were rheumatoid, arthritis, patient, education, information, knowledge, general practitioner, family doctor, and continuing medical education. Only articles in French or English were included. A panel of rheumatologists used the evidence thus compiled to develop recommendations for each question; gaps in evidence were filled by calling on the panelists' expert opinion. For each recommendation, the level of evidence and extent of agreement among panelists were specified. RESULTS: There were four general questions about the objectives, supports, and mode of delivery (group or one-on-one) of patient information and education, as well as on evaluating knowledge, and four specific questions on program content. The search identified 1235 articles; 144 were selected on the title and 118 of those on the abstract. Three abstracts presented at meetings were also kept. The evidence from the literature was presented to the panelists during interactive workshops. The panelists then developed eight recommendations, all of which were grade D because no published studies specifically addressed everyday clinical practice. Agreement among panelists ranged across recommendations from 85.7% to 100%. CONCLUSION: Recommendations about educating and informing patients with RA in everyday practice were developed. They should increase practice uniformity and ultimately optimize the management of patients with RA.

Physical examination and laboratory tests in the management of patients with rheumatoid arthritis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVES: To develop recommendations for the physical and laboratory-test follow-up of patients with rheumatoid arthritis (RA) seen in everyday practice, using evidence from the literature, supplemented with expert opinion when needed. METHODS: A scientific committee selected 7-10 questions using the Delphi consensus procedure. Evidence-based responses to each question were sought in the literature and were then used by a panel to develop recommendations. To fill in gaps in knowledge from the literature, the panelists relied on their personal opinion. RESULTS: The seven questions dealt with the physical and laboratory-test follow-up of RA and the factors predicting disease severity. The literature review identified 799 articles whose title and abstract suggested relevance to the study. Elimination of articles that provided no data on the study topic left 128 original articles. The panel developed seven recommendations, one for each question, which were accepted by consensus. CONCLUSION: Recommendations about the physical and laboratory-test follow-up of patients with RA seen in everyday practice were developed. Because they constitute an objective foundation built by consensus among experts, should improve the uniformity and quality of care provided to RA patients in everyday practice.

Structural evaluation in the management of patients with rheumatoid arthritis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVES: To develop French evidence-based recommendations for the structural evaluation of rheumatoid arthritis (RA) in everyday practice. METHODS: A scientific committee selected 10 questions using the Delphi consensus procedure. Evidence-based responses to each question were sought by searching the PubMed and Ovid databases and the abstract databases for the 2002, 2003, and 2004 annual meetings of the French Society for Rheumatology, the EULAR, and the American College of Rheumatology. The following indexing terms were used: rheumatoid arthritis, arthritis, patient, diagnostic imaging, radiography, joint, erosion, and joint space width. All articles published in French or English prior to May 2004 were identified. The evidence from these articles was reported to a panel of 77 rheumatologists working in hospital or office practice. The panel developed detailed recommendations, filling gaps in evidence with their expert opinion. The strength of each recommendation was determined. RESULTS: The 10 questions probed the structural evaluation of RA by plain radiography, magnetic resonance imaging (MRI), and ultrasonography, both for diagnostic and monitoring purposes. The literature search retrieved 673 publications, of which 166 were selected and reviewed. The panel developed 10 recommendations, one for each question, which were accepted by consensus. CONCLUSION: Recommendations relative to the diagnosis or monitoring of structural involvement in patients with RA in everyday practice were developed. They should help to improve practice uniformity and, ultimately, to improve the management of RA.

Influence of sex on disease severity in patients with rheumatoid arthritis.

OBJECTIVE: To determine whether patient's sex influences the severity of rheumatoid arthritis (RA) in terms of clinical severity or need for treatments. METHODS: This was a retrospective, single-center study. We compared 133 male patients with 133 female patients presenting with RA and matched for disease duration. Data collection included demographic characteristics, pattern of joint involvement, extraarticular manifestations, medical treatment, and joint surgery. Biological measures, HLA genotypes, Larsen radiological scores on radiographs of hands and feet, and Health Assessment Questionnaire (HAQ) results were obtained. RESULTS: Mean disease duration was 7.4 +/- 6.9 years. Concerning clinical pattern of involvement, sicca syndrome was more frequent in women than in men (p = 0.0003). There were no significant differences concerning absence or presence of at least one disease associated gene (HLA-DRB1*01 or *04) in our patients; however, women more often carried 2 disease associated genes (21% vs 11%). No other difference in clinical, biological, or radiological indicators was noted between the 2 populations. Concerning treatment, there was no difference for large joint arthroplasties; female patients underwent significantly more distal joint arthrodesis, 6.7% vs 1.5% (p = 0.03); they were prescribed slightly more disease modifying drugs, 3.33 vs 2.83 (p = 0.04); and showed a trend toward more large joint arthrodesis, 15% vs 7.5% (p = 0.05), and metacarpophalangeal joint arthroplasties, 5.2% vs 0.7% (p = 0.08). CONCLUSION: When patients are matched for RA duration, sex has little effect on the disease pattern and severity, yet women undergo more distal joint surgery.

Use of combination of leflunomide with biological agents in treatment of rheumatoid arthritis.

An Expert Panel Meeting was held in May 2004 to assess experience with combination therapy with leflunomide and biological agents in the treatment of rheumatoid arthritis (RA), to identify both optimal use of such combinations and precautions for use. Eleven published prospective or retrospective studies were reviewed, principally evaluating combination of leflunomide with infliximab, as well as patient registry data. Available data suggest that combination therapies are more efficacious than monotherapies, reflecting the complementarity of mechanisms of action. Information on side effects remains contradictory, and tolerability of these combinations may vary between different patient groups. In some studies, tolerability is equivalent to that seen with monotherapy; in others a high rate of adverse events has led to frequent treatment discontinuation. Dermatological reactions may be a specific side effect of these combination therapies. Combination therapy is considered justified for treatment of patients diagnosed early who are at risk for rapid progression and for patients who fail to respond to monotherapy. The majority of participants favored adding biological agents to a previously established leflunomide monotherapy rather than starting both treatments simultaneously. On the other hand, combination therapy should be considered with caution in patients with a history of treatment failure, with hepatic comorbidity, or with other autoimmune disease, and in immunocompromised patients. When considering initiation of combination therapy, it is important to provide full information to the patient on the potential benefits and risks of such treatment and to integrate patients as far as possible into the decision-making process.
