Abstract
OBJECTIVE The objective of this review was to estimate the population-based incidence of and determine the types of severe infection and deaths experienced by patients with rheumatoid arthritis taking biological agents. INTRODUCTION Since the late 1990s, various biological and synthetic drugs have been developed to treat rheumatoid arthritis. In recent years, the incidence of severe infection in patients with rheumatoid arthritis in Western nations has been determined by observational studies; however, no systematic review has been conducted on this topic. INCLUSION CRITERIA The following inclusion criteria were considered: i) observational studies on patients with rheumatoid arthritis treated with biological agents; ii) studies reporting the number of severe infections requiring hospitalization for treatment; iii) studies reporting person-years of observation data; and iv) studies based on rheumatoid arthritis registries, medical records from rheumatology centers, or insurance claim databases. METHODS PubMed, CINAHL, Embase, and Web of Science were searched to identify published studies. The reference lists of all studies selected for critical appraisal were screened for additional studies. Unpublished studies were searched on MedNar and OpenGrey databases. All the searches were updated on December 6, 2021. After removing the duplicates, 2 independent reviewers screened titles and abstracts against the inclusion criteria and then assessed full texts against the criteria. Two reviewers independently appraised the study and outcome levels for methodological quality using the critical appraisal instrument for cohort studies from JBI. Two reviewers extracted the relevant information related to severe infection and drugs. RESULTS Fifty-two studies from 21 countries reported severe infection rates associated with using 9 biologic agents. In total, 18,428 infections with 395,065 person-years of biologic drug exposure were included in the analysis. Thirty-five studies included infections in outpatients receiving intravenous antibiotic therapy. Fifteen studies reported the first episode of infection, and the remaining studies did not specify either the first or all of the episodes of infection. Inclusion of viral infection and/or opportunistic infection varied among studies. Fifteen studies reported the site of infection, and respiratory, skin/soft tissue, urinary tract infection, and sepsis/bacteremia were commonly reported. Ten studies reported the case fatality rates, ranging from 2.5% to 22.2%. Meta-analysis was conducted for 7 biologic agents and conventional disease-modifying antirheumatic drugs. The infection rate varied from 0.9 to 18.0/100 person-years. The meta-analysis revealed an infection rate of 4.2/100 person-years (95% CI 3.5-4.9) among patients receiving tumor necrosis factor inhibitors (heterogeneity 98.2%). The meta-analysis for the other 3 biologic agents revealed a point estimate of 5.5 to 8.7/100 person-years with high heterogeneity. Sensitivity analysis indicated that registry-based studies were less likely to have very low or very high infection rates compared with other data sources. The definition of infection, the patient composition of the cohorts, and the type of databases appeared to be the primary sources of clinical and methodological heterogeneity. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42020175137. CONCLUSIONS Due to high statistical heterogeneity, the meta-analysis was not suited to estimating a summary measure of the infection rate. Developing standardized data collection is necessary to compare infection rates across studies.

The beneficial effect of csDMARDs co-medication on drug persistence of first-line TNF inhibitor in rheumatoid arthritis patients: data from Czech ATTRA registry. Rheumatol Int 2022; 42:803-814. [PMID: 35338383 PMCID: PMC9007799 DOI: 10.1007/s00296-021-05072-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 12/15/2021] [Indexed: 10/31/2022]
Abstract
The study aimed to compare treatment retention for first-line TNF inhibitor (TNFi) in the ATTRA registry patients receiving either combination with conventional synthetic DMARDs or TNFi as monotherapy. A retrospective multicenter study analyzed data of all adult patients with rheumatoid arthritis (n = 3032) starting TNF inhibitor as the first-line biological therapy in combination with csDMARDs or in monotherapy from January 1st 2012 to December 31st 2020. Kaplan-Meier method was employed to calculate drug retentions. Survival curves of treatment retentions were compared through Log-rank test between the studied subgroups. The hazard ratio for drug discontinuation was assessed through univariate cox regression models. In patients who started the first line TNFi therapy, the median treatment retention was 47.7 (42.2; 53.1) months for combination therapy and 22.7 (14.9; 30.6) months for TNFi monotherapy (p < 0.001). Estimated one-year survival was higher in patients on TNFi combined with csDMARDs as compared with TNFi monotherapy (75.3% vs 65.7%); two-year survival rate was 63.2% vs 49.2%, three-year survival rate was 55.4% vs 42.4% and five-year survival 44.9% vs 26.4% of patients. The estimated survival on the first TNFi was higher in patients taking combination therapy with methotrexate than with other csDMARDs (p = 0.003). Use of csDMARDs co-medication was associated with significantly better first TNFi drug survival compared to monotherapy. The combination of TNFi with MTX is more effective than the combination with leflunomide, which did not demonstrate a significant effect.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disorder characterized by inflammation and bone erosion. The exact mechanism of RA is still unknown, but various immune cytokines, signaling pathways and effector cells are involved. Disease-modifying antirheumatic drugs (DMARDs) are commonly used in RA treatment and classified into different categories. Nevertheless, RA treatment is based on a "trial-and-error" approach, and a substantial proportion of patients show failed therapy for each DMARD. Over the past decades, great efforts have been made to overcome treatment failure, including identification of biomarkers, exploration of the reasons for loss of efficacy, development of sequential or combinational DMARDs strategies and approval of new DMARDs. Here, we summarize these efforts, which would provide valuable insights for accurate RA clinical medication. While gratifying, researchers realize that these efforts are still far from enough to recommend specific DMARDs for individual patients. Precision medicine is an emerging medical model that proposes a highly individualized and tailored approach for disease management. In this review, we also discuss the potential of precision medicine for overcoming RA treatment failure, with the introduction of various cutting-edge technologies and big data.

Abstract
INTRODUCTION COVID-19 is an acute respiratory viral infection that threatens people worldwide, including people with rheumatic disease, although it remains unclear to what extent various antirheumatic disease therapies increase susceptibility to complications of viral respiratory infections. OBJECTIVE The present study undertakes a scoping review of available evidence regarding the frequency and severity of acute respiratory viral adverse events related to antirheumatic disease therapies. METHODS Online databases were used to identify, since database inception, studies reporting primary data on acute respiratory viral infections in patients utilizing antirheumatic disease therapies. Independent reviewer pairs charted data from eligible studies using a standardized data abstraction tool. RESULTS A total of 180 studies were eligible for qualitative analysis. While acknowledging that the extant literature has a lack of specificity in reporting of acute viral infections or complications thereof, the data suggest that use of glucocorticoids, JAK inhibitors (especially high-dose), TNF inhibitors, and anti-IL-17 agents may be associated with an increased frequency of respiratory viral events. Available data suggest no increased frequency or risk of respiratory viral events with NSAIDs, hydroxychloroquine, sulfasalazine, methotrexate, azathioprine, mycophenolate mofetil, cyclophosphamide, or apremilast. One large cohort study demonstrated an association with leflunomide use and increased risk of acute viral respiratory events compared to non-use. CONCLUSION This scoping review identified that some medication classes may confer increased risk of acute respiratory viral infections. However, definitive data are lacking and future studies should address this knowledge gap.

Abstract
Safety concerns associated with many drugs indicated for the treatment of rheumatoid arthritis (RA) can be attenuated by the early identification of toxicity through routine laboratory monitoring; however, a comprehensive review of the recommended monitoring guidelines for the different available RA therapies is currently unavailable. The aim of this review is to summarize the current guidelines for laboratory monitoring in patients with RA and to provide an overview of the laboratory abnormality profiles associated with each drug indicated for RA. Recommendations for the frequency of laboratory monitoring of serum lipids, liver transaminases, serum creatinine, neutrophil counts, and platelet counts in patients with RA were compiled from a literature search for published recommendations and guidelines as well as the prescribing information for each drug. Laboratory abnormality profiles for each drug were compiled from the prescribing information for each drug and a literature search including meta-analyses and primary clinical trials data.

Abstract
Leflunomide modulates T-cell responses and induces a shift from the Th1 to Th2 subpopulation. This process results in a beneficial effect in diseases in which there is good evidence that T cells play a major role in both initiation and perpetuation of the inflammatory condition. Leflunomide has been successfully used for treating rheumatoid arthritis and psoriatic arthritis for many years. The active metabolite of leflunomide is teriflunomide, which has been approved for treating multiple sclerosis. Teriflunomide, just like the mother drug, inhibits dihydro-orotate dehydrogenase and synthesis of pyrimidine. The present review presents and discusses the safety profiles of leflunomide and teriflunomide, two drugs that are indeed the same, considering that much can be learned from the reported side effects of both.

Abstract
OBJECTIVES To develop and/or update fact sheets about TNFα antagonists treatments, in order to assist physicians in the management of patients with inflammatory joint disease. METHODS 1. selection by a committee of rheumatology experts of the main topics of interest for which fact sheets were desirable; 2. identification and review of publications relevant to each topic; 3. development and/or update of fact sheets based on three levels of evidence: evidence-based medicine, official recommendations, and expert opinion. The experts were rheumatologists and invited specialists in other fields, and they had extensive experience with the management of chronic inflammatory diseases, such as rheumatoid. They were members of the CRI (Club Rhumatismes et Inflammation), a section of the Société Francaise de Rhumatologie. Each fact sheet was revised by several experts and the overall process was coordinated by three experts. RESULTS Several topics of major interest were selected: contraindications of TNFα antagonists treatments, the management of adverse effects and concomitant diseases that may develop during these therapies, and the management of everyday situations such as pregnancy, surgery, and immunizations. After a review of the literature and discussions among experts, a consensus was developed about the content of the fact sheets presented here. These fact sheets focus on several points: 1. in RA and SpA, initiation and monitoring of TNFα antagonists treatments, management of patients with specific past histories, and specific clinical situations such as pregnancy; 2. diseases other than RA, such as juvenile idiopathic arthritis; 3. models of letters for informing the rheumatologist and general practitioner; 4. and patient information. CONCLUSION These TNFα antagonists treatments fact sheets built on evidence-based medicine and expert opinion will serve as a practical tool for assisting physicians who manage patients on these therapies. They will be available continuously at www.cri-net.com and updated at appropriate intervals.

Abstract
Several smaller retrospective case series have concluded that leflunomide (LEF) in combination with anti-TNF-alpha blocking agents appears to be effective and safe. Prospective case series and cohort studies have generally confirmed the efficacy of this combination. Overall, there is currently no evidence from controlled trials that an anti-TNF-alpha combination with LEF is as effective as an anti-TNF-alpha combination with methotrexate (MTX). We compared the effectiveness and safety of a therapeutic regimen associating subcutaneous anti-TNF-alpha agents, etanercept (ETN) and adalimumab (ADA), with leflunomide (LEF) or methotrexate (MTX), in a two year open-label study performed in clinical practice. We evaluated 96 patients with active rheumatoid arthritis undergoing therapy with ADA at the dose of 40 mg every other week, or with ETN at the dose of 50 mg/week for two years added to prednisolone (PDN) at the mean dose of 5.2±2.6 mg/day. Fifty-four of these patients were also undergoing therapy with MTX at the mean dose of 11.7±2.6 mg/week, while 42 patients were undergoing therapy with LEF at the daily dose of 20 mg. At 12 months, the analysis of variance showed an improvement of DAS28 in both groups (p<0.001), with a reduction in 33.3% of the patients in treatment with LEF and in 51.8% of the patients in treatment with MTX (p = 0.20). At 18 months, improvement was present in 33.3% of the patients in the LEF group and in 81.5% of the patients in the MTX group (p=0.001). This improvement seems to be independent of the anti-TNF-alpha agent, even if MTX produces the highest DAS28 reduction when used in association with ETN (p<0.078). We found no difference in drug discontinuation rates or in effectiveness measures between anti-TNFalpha+MTX and anti-TNFalpha+LEF. Our data showed a greater reduction of DAS28 in the MTX group and, in combination with ETN, better results after two years of therapy.

Abstract
Leflunomide, an inhibitor of the dihydroorotase dehydrogenase and thereby pyrimidine synthesis, was introduced and licensed for the treatment of rheumatoid arthritis in 1998. In the following years, its antiviral properties were discovered and the drug was used in solid organ transplantation for polyomavirus type BK or cytomegalovirus infection. Owing to its long half-life and weak interaction with the cytochrome system, special considerations apply in the use of this drug. This article summarizes the clinical experience with leflunomide in rheumatology and in the evolving field of transplantation.

Abstract
Objective To evaluate the effect of different concomitant disease modifying antirheumatic drugs (DMARDs) on the persistence with antitumour necrosis factor (anti-TNF) therapies in patients with rheumatoid arthritis (RA). Method This analysis included 10 396 patients with RA registered with the British Society for Rheumatology Biologics Register, a prospective observational cohort study, who were starting their first anti-TNF therapy and were receiving one of the following DMARD treatments at baseline: no DMARD (n=3339), methotrexate (MTX) (n=4418), leflunomide (LEF) (n=610), sulfasalazine (SSZ) (n=308), MTX+SSZ (n=902), MTX+ hydroxychloroquine (HCQ) (n=401) or MTX+SSZ+HCQ (n=418). Kaplan–Meier survival analysis was used to study the persistence with anti-TNF therapy in each DMARD subgroup up to 5 years. Multivariate Cox proportional hazard models, stratified by anti-TNF used and start year and adjusted for a number of potential confounders, were used to compare treatment persistence overall and according to the reason for discontinuation between each of the DMARD subgroups, using MTX as reference. Results One-year drug survival (95% CI) for the first anti-TNF therapy was 71% (71% to 72%) but this dropped to 42% (41% to 43%) at 5 years. Compared with MTX, patients receiving no DMARD, LEF or SSZ were more likely to discontinue their first anti-TNF therapy while patients receiving MTX in combination with other DMARDs showed better treatment persistence. Conclusions These results support the continued use of background DMARD combinations which include MTX. Consideration should be given to the discontinuation of LEF and SSZ monotherapy at the time anti-TNF therapies are started, with the possible exception of the SSZ+ETN combination.

Abstract
Leflunomide is a disease-modifying antirheumatic drug (DMARD) that has been in routine clinical use for the treatment of rheumatoid arthritis (RA) and psoriatic arthritis for a decade. In RA, clinical trials of up to two years' duration showed that leflunomide monotherapy was equivalent to methotrexate in clinical and radiographic disease outcomes (tender and swollen joint counts, physician and patient global assessments, American College of Rheumatology and Disease Activity Score responses, slowing or halting of radiographic progression). In a number of studies, quality of life measurements indicated that leflunomide is superior to methotrexate. Leflunomide has been studied in combination with methotrexate and shows efficacy in patients only partly responsive to this agent. Recent trials have shown that leflunomide can be used safely with biologic DMARDs, including antitumor necrosis factor agents and rituximab as part of the treatment algorithm in place of methotrexate as a cotherapy. Leflunomide has demonstrated efficacy as a monotherapy in psoriatic arthritis, and it also has a beneficial effect in psoriasis. Postmarketing studies have shown that retention on treatment with leflunomide is equal to methotrexate and superior to other DMARDs. In general, its side effect profile is acceptable compared with other DMARDS, with nausea, diarrhea, and hair fall occurring commonly, but only rarely leading to discontinuation. Liver toxicity is the most significant problem in clinical use although it is uncommon. Peripheral neuropathy, hypertension, pneumonitis, and cytopenia occur more rarely. Leflunomide is contraindicated in pregnancy and should be used with caution in women during child-bearing years. In this review, the place of leflunomide in therapy is discussed and practical advice informed by evidence is given regarding dosing regimens, safety monitoring, and managing side effects. Leflunomide remains one of the most useful of the nonbiologic DMARDs.

Abstract
Evidence is accumulating for the early sustained usage of disease-modifying anti-rheumatic drugs (DMARDs) in rheumatoid arthritis. Leflunomide was licensed for the treatment of rheumatoid arthritis in 1998. Postmarketing surveillance, case reports and observational studies have highlighted less common or unexpected adverse events. Therefore, it is appropriate that we review the benefit-risk profile of leflunomide after 10 years of widespread usage. A wide-based search of relevant literature was performed to formulate this assessment. The improvements in rheumatoid arthritis shown by double-blind, randomized controlled trials (RCTs) of leflunomide have now been shown to be maintained beyond 4 years in open-label extension studies. Leflunomide is comparable to methotrexate, but better than sulfasalazine at 24 months in only one study. However, tolerance in clinical practice research shows higher than expected withdrawal rates due to both toxicity and lack of efficacy when compared with methotrexate and placebo. Adverse events reported include gastrointestinal upset, hypertension, headache, hepatotoxicity and hair loss, as well as predisposition to infection and peripheral neuropathy. The incidence of gastrointestinal adverse effects for leflunomide is similar to sulfasalazine but higher than those seen with methotrexate. Serious drug-induced hepatotoxicity leading to hospitalization is rare (0.02%), but isolated fatalities from liver failure have been documented. It is considered likely, but not yet proven, that there may be an increased incidence of weight loss and interstitial lung disease with leflunomide. Leflunomide in combination with methotrexate or sulfasalazine is an effective regimen in RCTs utilizing placebo controls, but more research is needed to confirm its effectiveness in combination with other DMARDs, particularly biologicals. The active metabolite of leflunomide is teratogenic in animal studies and is also found in breast milk. Therefore, contraception is advised in both males and females of child-bearing potential. There are genetic, pharmacokinetic and biochemical reasons to explain variation in both patient response and adverse event profile. Hence, blood and blood pressure monitoring are recommended and therapeutic drug monitoring should be considered in clinical nonresponders. Leflunomide is an effective DMARD that sustains a clinical and radiological response comparable to sulfasalazine and methotrexate. However, adverse effects necessitate frequent monitoring. It should be used with caution in those of child-bearing potential and with pre-existing lung and liver disease.

Abstract
To compare the efficacy and safety of leflunomide (LEF)-anti-TNF-alpha combination therapy to methotrexate (MTX)-anti-TNF-alpha combination therapy in a group of patients with active rheumatoid arthritis (RA). We have recruited 120 patients with RA with a high disease activity despite being treated with MTX (15 mg/week) or LEF (20 mg/die) for 3 months, without side effects. In each of these patients, therapy with either MTX or LEF was continued and randomly combined with an anti-TNF-alpha drug: etanercept, infliximab, or adalimumab. Patients were assessed at study entry and at 4, 12, and at 24 weeks. The efficacy endpoints included variations in the DAS28-ESR and the ACR20, ACR50, and ACR70 responses. At each visit, any side-effect was recorded. There were no statistically significant differences in the DAS28 variations and in the ACR responses between the two groups or among the six subgroups. The number of discontinuation due to the appearance of serious side effects was higher, but not statistically significant, in the LEF-anti-TNF-alpha group than in the MTX-anti-TNF-alpha group. Other adverse events that did not necessitate the discontinuation of therapy occurred much more frequently in patients treated with MTX than in those treated with LEF. Anti-TNF-alpha drugs can be used in combination not only with MTX, but also with LEF, with the same probability of achieving significant clinical improvement in RA patients and without a significantly greater risk of serious adverse events. In contrast, it seems that combination therapy with LEF-anti-TNF-alpha is more readily tolerated than combination therapy with MTX-anti-TNF-alpha.

Abstract
Infliximab was the first monoclonal antibody to human necrosis factor alpha (TNFalpha) developed for treating rheumatoid arthritis (RA). This chimeric antibody binds with high affinity to both soluble and trans-membrane TNF and is able to reduce synovial inflammation, bone resorption and cartilage degradation. The efficacy of infliximab has been observed in active RA despite treatment with multiple disease modifying anti-rheumatic drugs (DMARDs), and in early disease with no prior treatment by methotrexate (MTX). Infliximab has been shown to reduce joint inflammation and to slow radiographic progression, in both clinical and non-clinical responders. Recent data suggest that using infliximab early in RA treatment increases the percentage of clinical remission and allows infliximab discontinuation. The recommended dosage of 3 mg/kg could be increased up to 10 mg/kg with partial efficacy of the dose escalation. Antibodies to infliximab have been observed in 7% to 61% of patients and are associated with a low trough level of infliximab and secondary response failure. Their occurrence could be prevented by co-medication with MTX. The combination of DMARDs other than MTX with infliximab was found to be safe and efficacious. Infections, principally tuberculosis, are increased in treated patients, and the risk is greater at higher dose. Even if the treatment is generally safe and well tolerated, patients treated with infliximab should be closely monitored.

Abstract
OBJECTIVES To assess the risk of serious and nonserious bacterial and viral infections associated with the use of biologic therapy (abatacept, adalimumab, anakinra, etanercept, infliximab, and rituximab) in patients with rheumatoid arthritis (RA). METHODS Information was derived from PubMed, EMBASE, and the Cochrane clinical trials register and database of systematic reviews and relevant congress abstracts up to and including February 2008. RESULTS Compared with the general population, patients with RA have a heightened risk of infection, including tuberculosis. Long-term clinical trials and postmarketing studies indicate that anakinra and the tumor necrosis factor (TNF) inhibitors are associated with an increased risk of infections versus conventional disease-modifying antirheumatic drugs (DMARDs), especially early in the course of treatment. The most common sites of infection are the respiratory tract (including pneumonia), skin and soft tissue, and the urinary tract. The risk of tuberculosis also appears higher with TNF inhibitors (in particular, infliximab) versus DMARDs, although this can be reduced by screening and prophylaxis. TNF inhibitors do not appear to significantly increase the risk of reactivating chronic viral infections. Influenza and pneumococcal vaccinations are generally effective in the face of TNF inhibitors or abatacept. Available data suggest that the risk of infections and serious infections with abatacept and rituximab may be similar to that of the TNF inhibitors. To date, there have been no reports from clinical trials of increased tuberculosis or opportunistic infections with abatacept or rituximab. CONCLUSIONS All marketed TNF inhibitors for compared to control RA appear to increase the risk of serious and nonserious infections compared with DMARDs. Although suggestive, data for abatacept and rituximab are less definitive and longer periods of patient exposure to these agents are needed before an assessment of their risks can be made.

Abstract
INTRODUCTION The disease activity in patients with rheumatoid arthritis has improved during the past decade. The availability of new drugs and also a better assessment of the disease have been proposed to be responsible for this improvement. In the present work we estimate the effect of these factors on disease activity and function in patients with rheumatoid arthritis at the beginning of the new century. METHODS The Estudio de la Morbilidad y Expresión Clínica de la Artritis Reumatoide (EMECAR) cohort was assembled in 2000 from the random sampling of rheumatoid arthritis patients registered in 34 centers. The cohort was composed of 789 patients who underwent a baseline assessment plus four annual follow-up visits in which functional ability (Health Assessment Questionnaire score), the disease activity score obtained from 28-joint count with three parameters (DAS28-3) and radiological progression (Larsen score) were recorded. The effect of the calendar year on the DAS28-3, the Health Assessment Questionnaire score, and the Larsen score was obtained from adjusted models in which all treatments were included as dummy variables. RESULTS The effect of time as the beta coefficient (95% confidence interval) for 2004, taking 2000 as a reference year, was -0.43 (-0.58 to -0.28) for the DAS28-3, 0.15 (0.07 to 0.22) for the Health Assessment Questionnaire score, and 4.4 (2.68 to 6.12) for the Larsen score. Treatment with new therapies, either leflunomide or TNF antagonists, increased in frequency from 1.1% (n = 8) in 2000 to 30.9% (n = 144) in 2004. Treatment with TNF antagonists (-0.28 (-0.5 to -0.05)) and with gold salts (-0.21 (-0.38 to -0.04)) was independently associated with a decrease in the DAS28-3 over time, whereas cyclosporin A treatment (0.45 (0.13 to 0.76)) was associated with an increase in disease activity. CONCLUSIONS The mean disease activity of rheumatoid arthritis has improved from 2000 to 2004. An explanation is the introduction of new therapies, but not solely. Other factors related to the calendar year, plausibly a better management of available drugs, show a greater effect on improvement than the drugs used.

Abstract
OBJECTIVE To compare outcome at 6 months in unselected "real-world" patients with rheumatoid arthritis treated with etanercept or infliximab as either monotherapy, cotherapy with methotrexate (MTX), or cotherapy with another disease-modifying antirheumatic drug (DMARD). METHODS A total of 2,711 subjects starting treatment with their first biologic agent (1,453 infliximab and 1,258 etanercept) were followed up for 6 months. Outcome was assessed using the European League Against Rheumatism (EULAR) response criteria. Ordinal regression was used to model the response in the MTX and other DMARD cotherapy groups relative to the monotherapy group separately for the 2 anti-tumor necrosis factor alpha agents, after adjusting for baseline differences. RESULTS Etanercept-treated patients had an increased likelihood of achieving a higher EULAR response category with cotherapy with MTX (odds ratio [OR] 2.0, 95% confidence interval [95% CI] 1.5-2.7) and with another DMARD (OR 1.2, 95% CI 0.9-1.6) as compared with monotherapy. For infliximab-treated patients, the likelihoods were 1.4 (95% CI 0.9-2.0) for MTX and 1.3 (95% CI 0.8-2.1) for other DMARDs versus monotherapy. Cotherapy with MTX or another DMARD produced significantly higher rates of remission with etanercept (12% and 11%, respectively) as compared with etanercept monotherapy (5%). Infliximab-treated patients showed similar remission rates in the MTX and other DMARD cotherapy groups (8% and 5%, respectively) as in the monotherapy group (7%). CONCLUSION In this study of real-world patients, the use of MTX and, to a lesser extent, other DMARDs as cotherapy with etanercept was associated with a higher likelihood of response. Although the infliximab guidelines suggest that MTX be used as cotherapy, in clinical practice, both monotherapy and cotherapy with DMARDs other than MTX are used. These data suggest that either of the latter strategies may be useful in patients who are intolerant to MTX.

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
Leflunomide (Arava, Aventis Pharmaceuticals) is an oral pyrimidine synthesis inhibitor with immunomodulatory and anti-inflammatory activity. This agent has demonstrated significant efficacy in the treatment of rheumatoid arthritis (RA) and psoriatic arthritis in randomised, double-blind, placebo-controlled trials. Both the efficacy and safety of leflunomide are maintained with long-term administration in patients with RA. Leflunomide compares favourably with other biological and non-biological agents used to treat RA in the incidence of adverse events and serious adverse events. Economic studies indicate that leflunomide is a cost-effective option in the treatment of RA. New investigations with leflunomide have focused mainly on combination regimens for the treatment of RA and the use of leflunomide in other inflammatory or autoimmune disorders.

Abstract
Rheumatoid arthritis is a chronic inflammatory systemic autoimmune disorder characterized by symmetric inflammation of synovial joints, leading to progressive erosion of cartilage and bone. Tumor necrosis factor-α antagonists have set a new therapeutic standard for rheumatoid arthritis. Tumor necrosis factor-α blocking agents, including infliximab, etanercept and adalimumab, have demonstrated substantial improvement in signs and symptoms, disability and quality of life, while significantly inhibiting joint damage in early and long-standing rheumatoid arthritis. The focus of this article will be the role of infliximab in the treatment of rheumatoid arthritis.

Abstract
Psoriasis patients deserve long-term control of their disease with optimal safety. Traditional agents (methotrexate, cyclosporine, retinoids, and photochemotherapy [PUVS]), although providing excellent short-term control, may produce acute or chronic toxicities, thus limiting their usage. Dermatologists are well versed in combination and rotational therapies for psoriasis, using these and other agents. With the advent of biologic therapies (three currently approved, and others pending), the potential for safer long-term psoriasis control is being realized. A review of the literature, plus our personal experience in using combinations of traditional agents and biologics, is presented.

Abstract
OBJECTIVE To investigate the influence of previous and concomitant leflunomide on the efficacy and safety of infliximab therapy in rheumatoid arthritis (RA) and to compare it to infliximab in combination with other disease-modifying anti-rheumatic drugs. METHODS RA patients starting infliximab therapy were prospectively followed from January 2000. Every 3 months data were collected regarding disease activity (DAS28), adverse events and treatment changes. In the primary analyses all patients were classified into a leflunomide group (LEF group) if they had used leflunomide during infliximab therapy or within 6 months prior to starting infliximab therapy, the latter because of the long half-life of leflunomide. All other patients were considered as controls (non-LEF group). Secondary drug survival analyses were performed with the LEF group consisting only of patients on active leflunomide at the start of infliximab (active LEF group). RESULTS A total of 162 RA patients started infliximab therapy (57 in the LEF group, 105 in the non-LEF group). No statistically significant differences in baseline characteristics were observed between the groups. Maximum follow-up time was 46 months for both groups. No differences in drug survival, disease activity or adverse events were observed between the groups. In both groups an increase in patients positive for antinuclear antibodies (ANA) was seen. ANA positivity at start did not predict DAS28 or the occurrence of adverse events. Secondary drug survival analyses showed no differences between the active LEF group and the non-LEF group. CONCLUSION The results indicate that the administration of infliximab after or simultaneously with leflunomide is safe and efficacious in RA patients.

Abstract
PURPOSE OF REVIEW Newer biologic immunomodulators such as interferons, tumor necrosis factor alpha (TNFalpha) inhibitors, and monoclonal antibodies have been introduced into the management of various inflammatory conditions. This review addresses adverse responses to these agents. RECENT FINDINGS Both interferon-alpha and interferon-beta have been associated with autoimmune phenomena. The ability of TNFalpha antagonists to cause significant adverse reactions appears to be substantial. These are either related to interference with TNFalpha activity or as consequence of the agents, either immunoglobulin or fusion protein, being recognized as foreign proteins, becoming themselves targets of an immune response. SUMMARY Although advancing the management of inflammatory conditions, biologic modifiers are attended by significant concerns. Identification of at risk groups and careful selection of appropriate patients will minimize occurrence of adverse events.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic inflammatory joint disease. Leflunomide, as an inhibitor of pyrimidine synthesis, has a different mechanism of action than other existing disease modifying anti-rheumatic drugs (DMARD). OBJECTIVES To determine the efficacy and toxicity of leflunomide compared to placebo or other DMARDs in the treatment of RA. SEARCH STRATEGY We conducted a search in MEDLINE, EMBASE, Current Contents and the Cochrane Controlled Trial Register for trials up to December 2001. We also hand-searched reference lists and consulted content experts. SELECTION CRITERIA Two independent reviewers selected the trials that met predetermined inclusion criteria. DATA COLLECTION AND ANALYSIS Two independent reviewers extracted data and assessed methodologic quality using standardized forms. MAIN RESULTS Six trials were included in this review. Using the ACR20 improvement criteria, there was an absolute difference in improvement of 28% (95% confidence interval: 21 - 35%) favouring leflunomide (232 out of 413 leflunomide treated patients compared to 89 out of 311 placebo patients met the criteria). There was no difference in ACR20 response rate between the patients treated with leflunomide and SSZ or MTX at 6 and 12 months. Other clinical outcomes were improved significantly in the leflunomide group compared to placebo but not different from SSZ or MTX. Withdrawals due to adverse events with leflunomide were 10% greater than placebo (70 out of 416 compared to 18 out of 311 respectively). Important adverse events included gastrointestinal symptoms, elevated liver function tests, alopecia, and infections. Overall adverse events and withdrawals in the leflunomide group were not significantly different from SSZ or MTX. REVIEWER'S CONCLUSIONS Leflunomide appears to improve all clinical outcomes and delay radiologic progression at both 6 and 12 months of treatment compared to placebo. Its efficacy and adverse events at 2 years of treatment are comparable to SSZ and MTX. Long-term efficacy and toxicity remains to be established.
