Abstract
OBJECTIVE To determine the factors most strongly associated with an increase in therapy of early rheumatoid arthritis (ERA). METHODS Data from the Canadian Early Arthritis Cohort (CATCH) were included if the patient had ≥ 2 visits and baseline and 6 months data. A regression analysis was done to determine factors associated with treatment intensification. RESULTS Of 1145 patients with ERA, 790 met inclusion criteria; mean age was 53.4 years (SD 14.7), mean disease duration 6.1 months (SD 2.8), 75% were female, baseline Disease Activity Score-28 (DAS28) was 4.7 (SD 1.8) and 2.9 (SD 1.8) at 6 months for included patients. Univariate factors for intensifying treatment were physician global assessment (MDGA; OR 7.8 and OR 7.4 at 3 and 6 months, respectively, p < 0.0005), swollen joint count (SJC; OR 4.7 and OR 7.3 at 3 and 6 months, p < 0.0005), and DAS28 (OR 3.0 and OR 4.6 at 3 and 6 months, p < 0.0005). In the regression model only MDGA was strongly associated with treatment intensification (OR 1.5 and OR 1.2 at 3 and 6 months, p < 0.0005); DAS28 was not consistently predictive (OR 1.0, p = 0.987, and OR 1.2, p = 0.023, at 3 and 6 months). DAS28 was the reason for treatment intensification 2.3% of the time, compared to 51.7% for SJC, 49.9% for tender joint count, and 23.8% for MDGA. For the same SJC, larger joint involvement was more likely to influence treatment than small joints at 3 months (OR 1.4, p = 0.027). CONCLUSION MDGA was strongly associated with an increase in treatment at 3 and 6 months in ERA, whereas DAS28 was not. Physicians rarely stated that DAS28 was the reason for increasing treatment.

Abstract
OBJECTIVE Our objective was to describe characteristics of Canadian patients with early arthritis and examine differences between those fulfilling 1987 and 2010 rheumatoid arthritis (RA) classification criteria. METHODS The Canadian Early Arthritis Cohort (CATCH) is a national, multicenter, observational, prospective cohort of patients with early inflammatory arthritis, receiving usual care, recruited since 2007. Inclusion criteria include age > 16 years; symptom duration 6-52 weeks; swelling of ≥ 2 joints or ≥ 1 metacarpophalangeal/proximal interphalangeal joint; and 1 of rheumatoid factor ≥ 20 IU, positive anticitrullinated protein antibodies (ACPA), morning stiffness ≥ 45 min, response to nonsteroidal antiinflammatory drug, or positive metatarsophalangeal joint squeeze test. Data from patients enrolled to March 15, 2011, were analyzed. RESULTS In total, 1450 patients met the eligibility criteria (1187 were followed). At baseline, mean age was 53 ± 15 years, symptom duration was 6.1 ± 3.2 months, Disease Activity Score (DAS28) was 4.9 ± 1.6, Health Assessment Questionnaire-Disability Index was 1.0 ± 0.7. Forty-one percent (n = 450) of patients had moderate (3.2 < DAS28 ≤ 5.1) and 46% (n = 505) had high (DAS28 > 5.1) disease activity; 28% of those with baseline radiographs (n = 250/908) had radiographic evidence of erosions. ACPA status was available for 70% (n = 831) of patients; 55% (n = 453) tested positive. Sixty percent (n = 718) of patients were treated with methotrexate (MTX) initially. Of 612 patients without erosions, 63% and 83% fulfilled 1987 and 2010 RA classification criteria, respectively. Seventy-three percent (n = 166) of those who did not fulfill 1987 criteria were newly identified by the 2010 criteria. These patients had less severe disease and more were MTX-naive compared to those satisfying the 1987 criteria. Forty-seven percent of all patients achieved remission at 1 year. CONCLUSION Patients with early RA present with moderate high disease activity; < 50% achieve remission at 1 year, despite MTX treatment in the majority. The 2010 RA classification criteria identify more patients with RA who would previously have been designated as having undifferentiated disease. However, these patients have lower disease activity at the time of identification.

Abstract
OBJECTIVE The Canadian Rheumatology Association (CRA) has developed recommendations for the pharmacological management of rheumatoid arthritis (RA) with traditional and biologic disease-modifying antirheumatic drugs (DMARD) in 2 parts. Part II, focusing on specific safety aspects of treatment with traditional and biologic DMARD in patients with RA, is reported here. METHODS Key questions were identified a priori based on results of a national needs-assessment survey. A systematic review of all clinical practice guidelines and consensus statements regarding treatment with traditional and biologic DMARD in patients with RA published between January 2000 and June 2010 was performed in Medline, Embase, and CINAHL databases, and was supplemented with a "grey literature" search including relevant public health guidelines. Systematic reviews of postmarketing surveillance and RA registry studies were performed to update included guideline literature reviews as appropriate. Guideline quality was independently assessed by 2 reviewers. Guideline characteristics, recommendations, and supporting evidence from observational studies and randomized trials were synthesized into evidence tables. The working group voted on recommendations using a modified Delphi technique. RESULTS Thirteen recommendations addressing perioperative care, screening for latent tuberculosis infection prior to the initiation of biologic DMARD, optimal vaccination practices, and treatment of RA patients with active or a history of malignancy were developed for rheumatologists, other primary prescribers of RA drug therapies, and RA patients. CONCLUSION These recommendations were developed based on a synthesis of international RA and public health guidelines, supporting evidence, and expert consensus in the context of the Canadian health system. They are intended to help promote best practices and improve healthcare delivery for persons with RA.

Abstract
OBJECTIVE To systematically identify and examine reports of sex-stratified pain measurements in patients with inflammatory arthritis. METHODS Data sources included PubMed (1950 to April 2010), Embase (1980 to April 2010), and manual searches of reference lists and conference abstracts. We included cohort studies and randomized trials comparing pain scores, treatment efficacy at reducing pain, or pain localization, between females and males with inflammatory arthritis [rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis, and reactive arthritis]. RESULTS Twenty-six cohorts and 1 randomized trial reported sex-stratified pain scores, and all but 1 cohort identified worse pain scores at enrollment in females. In a metaanalysis of mean visual analog scale (VAS) scores (0 to 10) in 16 RA cohort studies (reporting on 21,612 females and 6871 males), the standardized mean difference in VAS was 0.21 (95% CI 0.16, 0.26). Treatment with disease-modifying therapy results in improvement in mean scores for both sexes; however, female absolute scores remain higher. In 12 spondyloarthropathy cohorts reporting pain localization, females develop more peripheral arthritis during their disease course (68.9% vs 51.2%) but less inflammatory back pain (50.6% vs 66.4%). CONCLUSION We identified important sex differences in pain scores in inflammatory arthritis, with higher pain levels in females. In spondyloarthritis, females develop more peripheral arthritis and have less frequent spinal involvement compared to males. These differences may affect a clinician's perception of disease severity and activity, and thus influence management decisions.

Abstract
BACKGROUND This multicenter, open-label, prospective, single cohort study evaluated the effectiveness and safety of adalimumab in a clinical setting reflecting the Canadian standard of care for the treatment of patients with rheumatoid arthritis (RA). METHODS Patients ≥ 18 years of age with a history of active RA ≥ 3 months and fulfilling Canadian requirements for biological therapy received adalimumab 40 mg subcutaneously every other week for 12 weeks. Pre-study DMARD treatment regimens, corticosteroids, or NSAIDs were allowed throughout the study. The primary effectiveness outcome measure was the mean change in 28-joint disease activity score (DAS28) from baseline to Week 12. Secondary measures included the proportion of patients achieving joint remission (DAS28 < 2.6) and low-disease activity (DAS28 < 3.2) at Week 12, and European League Against Rheumatism (EULAR: moderate and good) and American College of Rheumatology (ACR: ACR20, 50, and 70) responses, as well as responses in ACR core components at Weeks 4, 8, and 12. Subgroup analysis included a comparison of patients naïve to biological DMARD (BDMARD) therapy versus BDMARD-experienced patients. Safety was assessed in terms of adverse and serious adverse events. RESULTS A total of 879 patients (mean disease duration > 12 years) were enrolled; 772 (87.9%) completed the 12-week period. Adalimumab treatment was associated with rapid and sustained improvements in the signs and symptoms of RA. Significant improvements in mean DAS28 score were observed as early as Week 4. After 12 weeks of adalimumab treatment, 15.3% and 28.9% of patients achieved clinical remission and low-disease activity, respectively. Similarly, significant improvements in ACR core components were observed as early as Week 4, with continued improvements occurring through 12 weeks. Patients naïve to BDMARD therapy demonstrated numerically greater clinical responses when compared with patients who had experienced prior BDMARD therapy, although both subgroups were associated with significant improvements from baseline. The rates and types of adverse events, as well as the results of laboratory measures, demonstrated that adalimumab was generally safe and well-tolerated. CONCLUSIONS This study demonstrated that, under conditions reflective of the normal clinical practice in Canada, adalimumab is an effective and safe treatment for patients with RA.

Abstract
It has been well established that children with a chronic disease, including those with inflammatory bowel disease (IBD) and juvenile idiopathic arthritis (JIA), report lower health-related quality of life (HRQOL) as compared to their healthy peers. Over the past 20 years there has been a significant emphasis on the development of measures of function and HRQOL for application in JIA and pediatric IBD. Several of the instruments currently used to assess HRQOL in children with immune-mediated inflammatory diseases (IMID), including the Juvenile Arthritis Quality of Life Questionnaire (JAQQ) and IMPACT questionnaire for pediatric IBD, were developed and validated by Canadian-based research teams. This review describes several disease-specific and generic instruments used to assess QOL in children with IBD or JIA. It also provides an overview of findings from several outcomes studies that applied the described tools in assessing HRQOL in children and adolescents with these conditions.

Abstract
Health-related quality of life (HRQOL) is an important measure of a patient's perception of his/her illness. Over the past 3 decades, numerous instruments have been developed to measure HRQOL in various patient populations, with 2 basic approaches: generic and disease-specific. While generic measures have broad application across different types and severity of diseases, disease-specific measures are designed to assess particular diseases or patient populations. All HRQOL instruments, however, must be valid and have high reliability and responsiveness. Validity ensures that the instrument measures what it is supposed to measure. Reliable instruments are able to reproducibly differentiate between subjects. Responsive evaluative measures are able to detect important changes in HRQOL during a period of time, even if those changes are small. HRQOL measures should also be interpretable, meaning that the differences in scores that correspond to small, moderate, and large HRQOL changes are easily identifiable. This article describes the steps in the development of HRQOL instruments from the conceptual framework to creation and testing. Several examples of generic and disease-specific instruments commonly used to evaluate HRQOL in patients with immune-mediated inflammatory diseases (IMID) are provided.

Abstract
OBJECTIVE To evaluate the safety and effectiveness of rituximab (RTX) in combination with methotrexate in patients with active rheumatoid arthritis (RA) after failure of a single tumor necrosis factor-α (TNF-α) inhibitor. Changes in patient-reported outcomes after primary treatment or retreatment with RTX and factors determining retreatment in clinical practice were also evaluated. METHODS In this phase 3b open-label, multicenter trial, patients received 2 slow infusions of RTX 1000 mg 14 days apart after premedication (primary treatment). Patients with a clinically relevant response could receive retreatment between 24 and 48 weeks. The primary endpoint was evaluation of safety. Secondary outcomes were safety of retreatment, effectiveness of primary treatment and retreatment, and changes in patient-reported outcomes after primary treatment or retreatment. RESULTS Of 120 patients enrolled at 36 centers and receiving primary RTX treatment, 77 received retreatment, 112 completed the 24-week primary treatment period, and 25 completed the 48-week primary treatment and retreatment period following a single course of RTX. The most common adverse events were mild to moderate nausea, vomiting, nasopharyngitis, and headache. No infections or infusion reactions were considered life-threatening. At 24 weeks, 58%, 27%, and 7% of patients achieved American College of Rheumatology 20, 50, and 70 improvements, respectively, and similar improvements were seen after retreatment. CONCLUSION RTX was well tolerated, with a low incidence of infusion reactions and infections. Efficacy results, including enhanced response in rheumatoid factor-positive patients, were comparable to those reported in the literature. Based on its efficacy and safety profile and retreatment schedule, RTX is an attractive treatment option for patients that have not responded to a single TNF-α inhibitor.

Abstract
OBJECTIVE The Canadian Rheumatology Association (CRA) has developed recommendations for the pharmacological management of rheumatoid arthritis (RA) with traditional and biologic disease-modifying antirheumatic drugs (DMARD) in 2 parts. Part 1 is reported here. METHODS The CRA Therapeutics Committee assembled a national working group of RA clinical experts, researchers, patient consumers, and a general practitioner. Treatment questions were developed a priori based on results of a national needs assessment survey. A systematic review of all clinical practice guidelines and consensus statements regarding treatment with traditional and biologic DMARD in patients with RA published between January 2000 and June 2010 was performed in Medline, Embase, and CINAHL databases, and the grey literature. Guideline quality was assessed by 2 independent reviewers, and guideline characteristics, recommendations, and supporting evidence from observational studies and randomized controlled trials were synthesized into evidence tables. The full working group reviewed the evidence tables and developed recommendations using a modified Delphi technique. RESULTS Five overarching principles and 26 recommendations addressing general RA management strategies and treatment with glucocorticoids and traditional and biologic DMARD were developed for rheumatologists, other primary prescribers of RA drug therapies, and patients with RA. CONCLUSION These recommendations were developed based on a synthesis of international guidelines, supporting evidence, and expert consensus considering the Canadian healthcare context with the intention of promoting best practices and improving healthcare delivery for persons with RA.

Abstract
OBJECTIVE To assess the efficacy and safety of abatacept plus methotrexate versus methotrexate alone in early erosive rheumatoid arthritis (RA). METHODS The AGREE was a 2-year phase IIIb multinational study in early (≤ 2 years) RA. During the double-blind period (year 1), patients were randomly assigned 1:1 to receive abatacept+methotrexate or methotrexate alone; all patients received open-label abatacept+methotrexate during year 2. Clinical outcomes assessed included 28-joint disease activity score (DAS28) defined remission, low disease activity score (LDAS), American College of Rheumatology (ACR) responses and physical function. Radiographic outcomes were assessed using the Genant-modified Sharp total score (TS). Safety was monitored throughout. RESULTS Of the 459 patients completing year 1, 433 patients (94.3%) completed year 2. DAS28-defined remission, LDAS, ACR and physical function were sustained through year 2 in the original abatacept+methotrexate group, with 55.2% in remission at 2 years. Upon introduction of abatacept in the methotrexate-alone group, additional patients achieved DAS28-defined remission (44.5% vs 26.9%), LDAS (60.4% vs 43.2%) and improved ACR 70 (49.8% vs 31.7%) for year 2 versus year 1. Less radiographic progression was observed at 2 years in the original abatacept+methotrexate group than the methotrexate-alone group (change in TS 0.84 vs 1.75, p<0.001). No new safety issues were seen. Similar rates of serious adverse events, serious infections and autoimmune events were observed in years 1 and 2. CONCLUSIONS The AGREE trial was the first to examine the impact of T-cell co-stimulation modulation with abatacept in patients with early erosive RA. Early treatment with abatacept+methotrexate resulted in greater sustainable clinical, functional and radiographic benefits than methotrexate alone, with acceptable safety and tolerability.

Abstract
AIM To measure the level of agreement and application of 10 international recommendations for treating rheumatoid arthritis (RA) to a target of remission/low disease activity. METHODS A 10-point Likert scale (1=fully disagree, 10=fully agree) measured the level of agreement with each of 10 recommendations. A 4-point Likert scale (never, not very often, very often, always) assessed the degree to which each recommendation was being applied in current daily practice. If respondents answered 'never' or 'not very often', they were asked whether they would change their practice according to the particular recommendation. RESULTS A total of 1901 physicians representing 34 countries participated. Both agreement with and application of recommendations was high. With regard to application of recommendations in daily practice, the majority of responses were 'always' and 'very often'. A significant percentage of participants who were currently not applying these recommendations in clinical practice were willing to change their practice according to the recommendations. CONCLUSION The results of this survey demonstrated great support of 'Treating RA to Target' recommendations among the international rheumatology community. Additional efforts may be needed to encourage application of the recommendations among certain clinicians who are resistant to changing their practice.

Abstract
Etanercept (ETN) is the first anti-tumor necrosis factor (TNF) agent to be approved for the treatment of rheumatoid arthritis (RA). Over the last 8 years, several clinical trials have shown its efficacy and safety in established and early RA, as well as a monotherapy or in combination with methotrexate. ETN not only reduces the signs and symptoms of RA, but also retards the progression of radiographic damage and improves the quality of life and function of patients. Its safety profile has been predictable since the first clinical trials with no new major safety concerns. Beyond its efficacy in RA, ETN is also indicated for the treatment of psoriatic arthritis. This current report reviews the evidence and the data in RA and psoriatic arthritis (PsA).

Abstract
OBJECTIVE To describe the longterm effectiveness and safety of etanercept in Canadian patients with psoriatic arthritis (PsA), treated over 24 months in clinical practice. METHODS Patients with active PsA (≥ 3 tender and ≥ 3 swollen joints) were recruited from 22 centers. Etanercept was administered at 50 mg/week subcutaneously. In addition to clinical assessment of skin and joint disease, conducted at baseline and at Months 6, 12, 18, and 24, regular patient interviews were conducted by telephone. Patient responses related to health status, disability, and work productivity were scored using the patient global assessment tool, the Health Assessment Questionnaire (HAQ), the Health and Labour Questionnaire (HLQ), and the Fatigue Severity Scale. RESULTS Out of 110 patients, 71 (65%) maintained etanercept treatment through the end of our study. All clinical measures of disease severity, including joint tenderness/pain, joint swelling, and Psoriasis Area and Severity Index score, improved significantly between baseline and Month 6 of etanercept treatment and remained constant thereafter. By the end of our study, 79% of patients achieved a Psoriatic Arthritis Response Criteria response, and 56% of patients achieved a 0.5-point improvement on HAQ, indicating clinically significant improvement in disability; 14% of patients finished our study free of disability (HAQ = 0). Patients' work productivity and fatigue improved significantly in parallel with these clinical and functional improvements. CONCLUSION Continuous treatment with etanercept over 2 years in a clinical setting improved clinical symptoms of PsA while reducing fatigue, improving work productivity, and ameliorating or eliminating disability.

Abstract
OBJECTIVE To identify predictive factors for total knee replacement (TKR) using data from MRI of knee osteoarthritis patients in a phase III multicentre disease-modifying osteoarthritis drug (DMOAD) study. METHODS Knee osteoarthritis patients from a 2-year clinical trial evaluating licofelone versus naproxen were investigated for the incidence of TKR of the study knee. Patients (n=161) who completed the study according to protocol were selected. Incidence of TKR was assessed blindly to the treatment following telephone interviews (n=123). RESULTS 18 TKR (14.6%) were performed in 4-7 years following enrolment in the original study. More TKR were performed within the naproxen than the licofelone group (61% vs 39%, p=0.232). Baseline score of bone marrow lesions (BML) in the medial compartment (p=0.0001), medial joint space width (JSW) as assessed by standardised radiographs (p=0.0008), presence of severe medial meniscal tear (p=0.004), medial meniscal extrusion (p=0.013), and C-reactive protein level (p=0.049) were strong predictors of TKR. Changes at the end of the study also yielded strong predictors: change in cartilage volume of the medial compartment (p=0.005) and of the global knee (p=0.034), reduction in the JSW of greater than 7% (p=0.009), and WOMAC pain (p=0.009) and function (p=0.023) scores. Multivariate analysis showed that baseline severe medial meniscal tear (p=0.023) and presence of medial BML (p=0.025) were the strongest independent long-term predictors of TKR. CONCLUSION This study shows that in the context of osteoarthritis trials, clinical data and structural changes identified by MRI allow prediction of a 'hard' outcome such as TKR. The findings support the usefulness and predictive value of MRI in defining study outcome in DMOAD trials.

Abstract
The introduction of anti-tumor necrosis factor (TNF) therapies has dramatically improved the treatment of immune-mediated inflammatory diseases and provides treatment options for patients who do not respond to conventional disease-modifying antirheumatic drugs. However, the use of anti-TNF therapies still needs to be optimized. Dropoff rates, patients' lack of response, and toxicity are issues that need to be addressed to render these therapies more effective for more patients.

Abstract
OBJECTIVES To evaluate prevalence of dose escalation among RA patients in normal clinical practice treated with etanercept, adalimumab or infliximab and to estimate its economic impact. METHODS A retrospective observational study of 739 patients with RA receiving continuous treatment with etanercept (n=319), adalimumab (n=313) or infliximab (n=107) for 18 months. Dose escalation, intensification of concomitant DMARDs and risk of dose escalation were evaluated, as well as costs. RESULTS Significantly more patients prescribed adalimumab (10%, p<0.001) or infliximab (35%, p<0.001) experienced dose escalation compared with patients treated with etanercept (3%). DMARD or steroid dose adjustment, when added as criteria of escalation, occurred more often among patients treated with adalimumab (28%; p=0.022) or infliximab (47%; p<0.001) than those prescribed etanercept (19%). Independent of confounding covariates, hazard of dose escalation was significantly higher for either infliximab (28.1-fold) or adalimumab (4.9-fold) relative to etanercept. Escalation among subjects treated with either infliximab or adalimumab incurred statistically significant increases in total cost of care compared with non-escalators whereas such differences observed for subjects treated with etanercept were not significant. CONCLUSIONS Patients receiving monoclonal antibody therapies, adalimumab or infliximab, had significantly higher rates of dose escalation than patients receiving the soluble TNF receptor, etanercept, and related costs were higher.

Abstract
OBJECTIVE Serological markers are thought to be useful in predicting which patients with early inflammatory arthritis (EIA) will progress to RA. The objective of this study is to determine the per cent RF and anti-CCP seroconversion in EIA patients at 1-5 years of follow-up: 80% of established RA is RF or CCP positive. METHODS We conducted a systematic literature review of all English publications and recent abstracts from ACR and EULAR. Patients ≥16 years of age with at least one swollen joint and symptoms < 2 years were included. RESULTS Twelve publications met the criteria: 10 studies included data on RF, while only 5 addressed anti-CCP. Sample sizes ranged from 15 to 395 and follow-up was 6-60 months. There was marked heterogeneity between studies; therefore, results could not be pooled for a meta-analysis. Baseline RF and anti-CCP positivity was also highly variable: 8-55 and 4-45%, respectively. Seroconversion rates for EIA were 1.9-5.0% at up to 30 months follow-up for RF and 1.3-8.9% at up to 60 months follow-up for anti-CCP. CONCLUSION There is minimal change in RF or anti-CCP positivity up to 5 years of follow-up. Prevalence data for RF in established RA is significantly higher than the baseline values reported here. The low rates of seroconversion would suggest a lower prevalence in EIA and the reason for this difference remains unknown. It is unclear whether antibody-negative patients are more likely to remit and be lost to follow-up in established RA populations.

Abstract
OBJECTIVES To explore the impact of disease-modifying osteoarthritis drug (DMOAD) treatment on biomarker levels and their correlation with cartilage volume loss and disease symptoms in a 2-year phase III clinical trial in patients with knee OA. METHODS 161 patients with knee OA (according-to-protocol population) were selected from a 2-year DMOAD trial studying the effect of licofelone (200 mg twice daily) versus naproxen (500 mg twice daily). Clinical evaluation of patients was carried out using the Western Ontario and McMaster Universities (WOMAC) questionnaire. Biomarker measurements of matrix metalloproteinase (MMP)-1, MMP-3, interleukin (IL)-6, C reactive protein (CRP), cartilage oligomeric matrix protein (COMP) and type I collagen C-terminal telopeptide (CTX-I) in serum, type II collagen C-terminal telopeptide (CTX-II) in urine, and knee MRI were performed at baseline and 2 years. RESULTS Over time an increase occurred in all biomarker levels with the exception of IL-6, CRP and CTX-II which decreased. The increase in MMP-1 and MMP-3 was significantly less (p = 0.05; p < 0.01, respectively) in the licofelone group. The baseline MMP-1 level was significantly but inversely predictive of cartilage volume loss for the medial compartment in both univariate (p = 0.04) and multivariate (p ≤ 0.04) regression analyses, and COMP, a predictor for the lateral compartment, in both univariate and multivariate models (p < 0.01). Baseline levels of IL-6 and CRP also showed a significant relationship with volume loss for the medial compartment (univariate analysis, p = 0.04 and p = 0.01, respectively; multivariate analysis, p = 0.03, p = 0.01). A significant association (univariate) was observed between the change in the levels of MMP-1 (p = 0.03) and MMP-3 (p = 0.02) and cartilage volume loss (lateral compartment) over 2 years. Baseline levels of CTX-I correlated (p = 0.02) with an increase in the size of the bone marrow lesion in the medial compartment. The baseline CRP levels correlated with worsening of symptoms: WOMAC total index (p < 0.01), pain (p < 0.01) and function (p < 0.01). CONCLUSION Higher baseline values of IL-6, CRP and COMP are predictive of greater risk of cartilage loss in OA. However, over time a reduction in MMP-1 and MMP-3 levels correlated best with reduction in cartilage volume loss and the effect of drug treatment. Baseline CRP was found to be a good predictor of the symptomatic response to treatment.

Abstract
OBJECTIVE To develop recommendations for the use of methotrexate (MTX) in patients with rheumatoid arthritis. METHODS Canadian rheumatologists who participated in the international 3e Initiative in Rheumatology (evidence, expertise, exchange) in 2007-2008 formulated 5 unique Canadian questions. A bibliographic team systematically reviewed the relevant literature on these 5 topics. An expert committee consisting of 26 rheumatologists from across Canada was convened, and a set of recommendations was proposed based on the results of systematic reviews combined with expert opinions using a nominal group consensus process. RESULTS The 5 questions addressed drug interactions, predictors of response, strategies to reduce non-serious side effects, variables to assess clinical response, and incorporating patient preference into decision-making. The systematic review retrieved 93 pertinent articles; this evidence was presented to the expert committee during the interactive workshop. After extensive discussion and voting, a total of 9 recommendations were formulated: 2 on drug interactions, 1 on predictors of response, 2 on strategies to reduce non-serious side effects, 3 on variables to assess clinical response, and 1 on incorporating patient preferences into decision-making. The level of evidence and the strength of recommendations are reported. Agreement among panelists ranged from 85% to 100%. CONCLUSION Nine recommendations pertaining to the use of MTX in daily practice were developed using an evidence-based approach followed by expert/physician consensus with high level of agreement.

Abstract
OBJECTIVE To determine through a systematic literature search the predictors of clinical response and radiographic progression in adult patients with rheumatoid arthritis (RA) treated with methotrexate (MTX) monotherapy. METHODS A systematic literature search using Medline, Embase, and the Cochrane Central Register of Controlled Trials, in May 2008, and review of abstracts of the annual congresses of the American College of Rheumatology (2006-2007) and the European League Against Rheumatism (2002-2007) was performed, as part of a national initiative to develop guidelines for the use of MTX in RA. RESULTS Nine studies fulfilled the criteria set for this literature search. Male sex, low disease activity measured by composite scores (DAS or SDAI), and nonutilization of prior DMARD were predictive of good clinical response to MTX. Patients with early RA who are rheumatoid factor-positive and smokers tend to have lower response. However, this last association has not been found for patients with established disease. High disease activity before introduction of MTX monotherapy and higher activity during followup at 3 months is a predictor of more severe radiographic progression. CONCLUSION Among factors found to be predictive of clinical and radiographic outcomes of patients with RA treated with MTX, no factor was found to have a high predictive value. Variability in efficacy measures and statistical tests made it difficult to compare results. Followup of disease activity after 3 to 6 months of treatment seems to be a better and more useful predictor than baseline patient characteristics.

Abstract
OBJECTIVE Patients with rheumatoid arthritis (RA) often have comorbidities that require multiple medications. Several of these medications may alter the efficacy or increase the toxicity of methotrexate (MTX). The purpose of our study was to determine which drugs used in combination with MTX (excluding disease modifying antirheumatic drugs, folic and folinic acid, corticosteroids, and biologic agents) enhance side effects or toxicity of MTX or lower its efficacy. METHODS A systematic literature search was performed with Medline, Embase, Cochrane Register and Database, and abstracts from the 2006/2007 annual congresses of the American College of Rheumatology and the European League Against Rheumatism. A manual search of the citation lists of retrieved publications was performed. RESULTS Of the 1172 articles identified, 67 were included: 21 pharmacokinetics studies, 5 observational studies, and 78 case reports. Most medications do not significantly affect the pharmacokinetics profile of MTX. Among the clinical studies, cytopenia and elevation of liver enzymes were the main reported toxicities. The use of trimethoprim-sulfamethoxazole (TMP-SMX) was mentioned as a risk factor for developing cytopenia in one observational study and in 17 case reports. Thirty case reports of cytopenia were attributed to the use of concomitant nonsteroidal antiinflammatory drugs, including acetylsalicylic acid. Two studies described mild abnormalities of liver enzymes with the use of isoniazid, and one study with the use of high-dose ASA. CONCLUSION Based on the published literature, MTX has limited drug interactions, with the exception of TMP-SMX and high-dose ASA, which can exacerbate toxicity of MTX. The clinical significance of these interactions has not been substantiated by extensive clinical observations.

Abstract
Background Aiming at therapeutic targets has reduced the risk of organ failure in many diseases such as diabetes or hypertension. Such targets have not been defined for rheumatoid arthritis (RA). Objective To develop recommendations for achieving optimal therapeutic outcomes in RA. Methods A task force of rheumatologists and a patient developed a set of recommendations on the basis of evidence derived from a systematic literature review and expert opinion; these were subsequently discussed, amended and voted upon by >60 experts from various regions of the world in a Delphi-like procedure. Levels of evidence, strength of recommendations and levels of agreement were derived. Results The treat-to-target activity resulted in 10 recommendations. The treatment aim was defined as remission with low disease activity being an alternative goal in patients with long-standing disease. Regular follow-up (every 1–3 months during active disease) with appropriate therapeutic adaptation to reach the desired state within 3 to a maximum of 6 months was recommended. Follow-up examinations ought to employ composite measures of disease activity which include joint counts. Additional items provide further details for particular aspects of the disease. Levels of agreement were very high for many of these recommendations (≥9/10). Conclusion The 10 recommendations are supposed to inform patients, rheumatologists and other stakeholders about strategies to reach optimal outcomes of RA based on evidence and expert opinion.

Abstract
The goal of treatment for patients with rheumatoid arthritis (RA) is to achieve remission, or at least a low disease activity state. A variety of useful and practical tools are available to rheumatologists to assess patient prognosis and evaluate response to treatment in clinical practice. Frequent assessments, ideally every 1 to 3 months, allow rheumatologists to adjust therapy according to patient outcomes. For patients who fail to respond to treatment with classic disease modifying antirheumatic drugs, combination therapies with biologic agents offer improved outcomes.

Abstract
BACKGROUND AND OBJECTIVE Tumor necrosis factor (TNF) antagonists, including etanercept (a soluble TNF receptor) and infliximab (an anti-TNF monoclonal antibody) are used in the treatment of patients with rheumatoid arthritis (RA). The purpose of this study was to evaluate the effectiveness and safety of 50 mg etanercept weekly in subjects with RA who have failed infliximab therapy. METHODS This phase 4, multicenter, open-label, single-arm, 16-week observational study enrolled subjects who had experienced primary (failure to achieve an initial response) or secondary (failure to maintain an initial response) infliximab failures. Effectiveness was measured using European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR) response criteria and laboratory assessments were used to evaluate levels of inflammation, lymphotoxin alpha, drug concentrations, and antibodies to infliximab. Safety endpoints included incidence of serious adverse events. CLINICAL TRIAL REGISTRATION This trial was registered under U.S. National Institutes of Health ClinicalTrials.gov identifier NCT00099554. RESULTS At week 16, over half (62%; 95% CI = 55, 69) of all subjects in the trial achieved a good or moderate EULAR response (DAS28) with etanercept. Using ACR criteria, after 16 weeks of etanercept therapy, 45% (95% CI = 38, 52) of all subjects had achieved an ACR20 response. Benefits were noted in tender and swollen joint counts, subject and physician global assessments, joint pain, and the Health Assessment Questionnaire. Outcomes were similar between subjects with primary and secondary infliximab failures. Levels of lymphotoxin alpha did not appear to affect response to etanercept. Potential limitations included the lack of a washout period, short duration of the trial, and the number of subjects who did not receive all doses of etanercept. CONCLUSION In this open-label, uncontrolled study, subjects with moderate to severe RA who failed to respond or who lost their initial response to infliximab safely benefited from receiving etanercept.

Abstract
Objectives: To assess the efficacy and safety of abatacept in methotrexate-naive patients with early rheumatoid arthritis (RA) and poor prognostic factors. Methods: In this double-blind, phase IIIb study, patients with RA for 2 years or less were randomly assigned 1 : 1 to receive abatacept (∼10 mg/kg) plus methotrexate, or placebo plus methotrexate. Patients were methotrexate-naive and seropositive for rheumatoid factor (RF), anti-cyclic citrullinated protein (CCP) type 2 or both and had radiographic evidence of joint erosions. The co-primary endpoints were the proportion of patients achieving disease activity score in 28 joints (DAS28)-defined remission (C-reactive protein) and joint damage progression (Genant-modified Sharp total score; TS) at year 1. Safety was monitored throughout. Results: At baseline, patients had a mean DAS28 of 6.3, a mean TS of 7.1 and mean disease duration of 6.5 months; 96.5% and 89.0% of patients were RF or anti-CCP2 seropositive, respectively. At year 1, a significantly greater proportion of abatacept plus methotrexate-treated patients achieved remission (41.4% vs 23.3%; p<0.001) and there was significantly less radiographic progression (mean change in TS 0.63 vs 1.06; p = 0.040) versus methotrexate alone. Over 1 year, the frequency of adverse events (84.8% vs 83.4%), serious adverse events (7.8% vs 7.9%), serious infections (2.0% vs 2.0%), autoimmune disorders (2.3% vs 2.0%) and malignancies (0.4% vs 0%) was comparable for abatacept plus methotrexate versus methotrexate alone. Conclusions: In a methotrexate-naive population with early RA and poor prognostic factors, the combination of abatacept and methotrexate provided significantly better clinical and radiographic efficacy compared with methotrexate alone and had a comparable, favourable safety profile.

Analysis of the precision and sensitivity to change of different approaches to assess cartilage loss by quantitative MRI in a longitudinal multicentre clinical trial in patients with knee osteoarthritis. Arthritis Res Ther 2008; 10:R129. [PMID: 18986534 PMCID: PMC2656228 DOI: 10.1186/ar2543] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2008] [Revised: 09/17/2008] [Accepted: 11/05/2008] [Indexed: 02/06/2023] Open
Abstract
Introduction Cartilage thickness and volume loss measurements using quantitative magnetic resonance imaging (qMRI) are suggested to detect significant cartilage changes over short time intervals. We aimed to compare these two different approaches looking at the global knee and subregions, using data from an osteoarthritis (OA) multicentre randomised clinical trial. Methods Three hundred and fifty-five patients with symptomatic knee OA were recruited for a two-year, double-blind, randomised clinical trial evaluating the effect of 200 mg licofelone twice daily and 500 mg naproxen twice daily on cartilage loss, and 301 patients had baseline MRI. MRIs were performed at baseline, 6, 12 and 24 months. Cartilage volume and thickness in the global joint, medial and lateral compartments, and central weight-bearing subregions of the medial and lateral femoral condyles and tibial plateaus were analysed. Data were analysed for the mean value imputed for intent-to-treat (ITT-MVI) and statistical analyses were performed using two-sample Student's t-test. Results Cartilage mean thickness loss in the global joint, lateral and medial compartments, as well as in medial compartments stratified according to patients with or without meniscal extrusion, was significantly less in the licofelone compared with the naproxen group at 12 and 24 months. Interestingly, these data were similar to those found when using cartilage volume loss as an outcome. Although greater cartilage volume and mean thickness loss was seen in central weight-bearing subregions of the medial and lateral compartments compared with the whole compartment and also in patients with meniscal lesions/extrusion, suggesting good sensitivity to change, its high standard deviation precluded for the condyles a high statistical power and abrogated statistically significant differences between the treatment groups. Conclusions These data demonstrate that both the measurement of cartilage thickness and that of cartilage volume provide the same level of sensitivity to estimate cartilage loss in a clinical trial. However, the potential of gaining statistical power with the use of thickness/volume change in knee subregions as an outcome seems negated by high inter-patient variability. Moreover, there is no superiority in statistical power by selecting patients with meniscal extrusion.

Abstract
OBJECTIVES Synovitis in knee osteoarthritis (OA) patients is a significant risk factor for disease progression. This study aimed at developing a magnetic resonance imaging (MRI) scoring system allowing reliable and sensitive assessment of synovitis severity in knee OA patients without the use of a contrast agent. METHODS Imaging was performed without contrast agent, using a 1.5T and a knee coil. For the synovial membrane, the MRI exam included two axial sequences: a T2-weighted (synovial fluid) and a gradient echo (GRE) (synovial membrane). Synovial membrane thickness was measured on four regions of interest (ROI): medial and lateral recesses, and medial and lateral suprapatellar bursa, with each graded/scored from 0 to 3, for a maximum of 12. A validation study was performed on a cohort of 27 knee OA patients having MRI at baseline. A subset of 14 patients had an additional MRI acquisition and symptom assessment at Day 60. Evaluation of disease symptoms was done with Western Ontario and McMaster Universities OA Index and visual analog scale, and of cartilage volume, menisci and subchondral bone, with MR images from a 3D spoiled gradient recalled (SPGR) sequence. RESULTS The synovial membrane thickness grade was 1.9+/-0.5 (mean+/-SD) with a score of 7.1+/-2.3. The intra-reader (r=0.91) and inter-reader (r=0.82) correlation coefficients were excellent (P<0.0001). The medial compartment grade was 1.9+/-0.6 and score was 3.4+/-1.4, and of the lateral compartment were 2.0+/-0.7 and 3.7+/-1.5, respectively. The grade and score for the suprapatellar bursa and recess were 1.8+/-0.7 and 3.5+/-1.5, and 2.1+/-0.5 and 3.9+/-0.9, respectively. No statistically significant differences in the ROI score and grade were observed between medial and lateral compartments or between recess and suprapatellar bursa. A positive correlation was found between the global severity of synovitis at baseline and the presence of a medial meniscal extrusion (P<0.04), and the loss of cartilage volume at 60 days (P<0.03). CONCLUSION This newly developed MRI technology for the assessment of synovial membrane thickness in knee OA patients was shown to be accurate and reproducible.

Abstract
OBJECTIVE In a multicentre study to explore the effects of licofelone as a disease-modifying osteoarthritis drug in comparison with naproxen in patients with knee osteoarthritis (OA), using MRI and x-ray examination. METHODS Patients with knee OA (n = 355) were randomised to receive either licofelone (200 mg twice a day) or naproxen (500 mg twice a day). MRI and x-ray examinations were performed at baseline, 6 months (MRI only), 12 and 24 months. MRI was used to assess quantitatively changes in cartilage volume, and x-ray examinations (Lyon-Schuss) to measure changes in the mean and minimum joint space width (JSW) in the medial compartment. Questionnaires probing symptoms were completed. Data were presented as intention to treat (ITT) and according to protocol (ATP). RESULTS Cartilage volume loss in the global joint and medial and lateral compartments was significantly less in the licofelone than in the naproxen group for ITT at 12 and 24 months and for ATP at all times except in the medial compartment. Patients with medial meniscal extrusion had a greater loss of cartilage volume. In these patients, licofelone markedly reduced the cartilage loss for both ITT and ATP at 12 and 24 months. Although licofelone showed less reduction in the JSW than naproxen, this did not reach significance. All clinical variables were improved at 24 months (p<0.001) for both groups, with a good safety profile. CONCLUSION Licofelone and naproxen were equally effective in reducing OA symptoms; however, licofelone significantly reduced cartilage volume loss over time, thus having a protective effect in patients with knee OA. This study proves the superiority of quantitative MRI over x-ray examinations in a multicentre clinical trial.

Abstract
The objective of this study was to identify, on a symptomatic knee osteoarthritis (OA) cohort, the risk factors associated with the progression of the disease. More specifically, we investigated the correlation between knee cartilage volume loss from subregions over the span of 24 months by means of quantitative magnetic resonance imaging (qMRI) with demographic, clinical, radiological, and MRI structural changes. A cohort of 107 patients with knee OA selected from a large trial evaluating the effect of a bisphosphonate underwent x-rays and MRI of the knee at baseline and 24 months. Joint space width (JSW) and joint space narrowing (JSN) and cartilage volume loss over time in subregions of the tibial plateaus and femoral condyles were quantitated. Structural changes in the subchondral bone (hypersignal) and in the menisci (tear and extrusion) were also evaluated. The greatest cartilage volume loss was found in the medial compartment, and risk factors included female gender, JSW, meniscal lesions, and bone changes at baseline. Subregion analysis revealed that the greatest cartilage volume loss at 24 months was found in the central area of the medial tibial plateau (15%; p < 0.0001) and of the medial femoral condyle (12%; p < 0.0001). These findings were associated with the presence at baseline of meniscal extrusion, particularly severe meniscal extrusion, medial and severe meniscal tear, bone hypersignal, high body mass index (BMI), smaller JSW, increases in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and patient global scores over time, and greater JSN. Parameters predicting medial central femoral condyle cartilage volume loss at 24 months were lateral meniscal tear, SF-36 and BMI at baseline, and JSN. At the medial central tibial plateau, the parameters were severe meniscal extrusion, severe lateral meniscal tear, and bone hypersignal in the lateral compartment at baseline, and WOMAC pain change. Meniscal damage and bone changes are the features most closely associated with the greatest subregional cartilage volume loss. Interestingly, for the first time, JSN was strongly associated with cartilage loss in the central areas of plateaus and condyles. This study also further confirms the correlation between cartilage volume loss and JSN and symptomatic changes at 24 months.

Abstract
OBJECTIVE The present study was a randomized, parallel, double-blind comparison between controlled-release (CR) tramadol and sustained-release (SR) diclofenac in patients with chronic pain due to osteoarthritis of the hips and/or knees. METHODS Patients with at least moderate pain intensity, and having received analgesics over the past three months, underwent a two- to seven-day washout of current analgesics before initiation of 200 mg CR tramadol or 75 mg SR diclofenac. During the eight-week study, patients returned to the clinic biweekly. CR tramadol doses were titrated to a maximum of 200 mg, 300 mg or 400 mg per day. SR diclofenac doses were titrated to 75 mg or 100 mg once daily, or 75 mg twice a day based on pain relief and the presence of side effects. For rescue analgesic, patients took acetaminophen as needed, up to 650 mg three times a day. RESULTS Forty-five patients on CR tramadol and 52 patients on SR diclofenac were evaluable. Significant improvements from prestudy treatment were shown for visual analogue scale pain (P=0.0001), stiffness (P<0.0005) and physical function (P=0.0001) scores for both treatments. There were no significant differences between the two treatments in the Western Ontario and McMaster Universities subscales, overall pain, pain and sleep, or the clinical effectiveness evaluation. Overall incidence of adverse events was similar in both groups, with more opioid-related adverse events with CR tramadol, and two serious adverse events occurring with the use of SR diclofenac. CONCLUSIONS CR tramadol is as effective as SR diclofenac in the treatment of pain due to knee or hip osteoarthritis, with the potential for fewer of the serious side effects that characterize nonsteroidal anti-inflammatory drug administration.

Abstract
Utility assessment and cost-utility analyses such as costs/quality-adjusted life-years (QALY) are frequently presented to demonstrate the value of new treatment options in rheumatoid arthritis (RA). However, utility indicators require various methods that introduce significant methodological challenges, which directly influence the results and ensuing reimbursement decisions. Our objective was to review and discuss these challenges and the validity of frequently used utility assessment techniques in the context of RA. Coding the intensity of preferences or variations in patient satisfaction in order to assess utility implies extreme mathematical assumptions about a patient's rationality regarding his/her preferences towards different given health states. The construction and assumptions of commonly used "direct approaches" (standard gamble, time tradeoff, visual analog scale) and indirect approaches (EQ5D, HUI, SF6D) are presented. Other approaches such as transformation in utility of data from clinical (Health Assessment Questionnaire) or quality of life instruments ("mapping technique") are analyzed as they appear to generate uncertainty and a wide variation in estimated utility values in the context of RA. Utility assessment and cost-utility analyses in RA, which form the basis of the QALY, are frequently published and often requested by health technology assessment agencies to assist -reimbursement decisions. However, when interpreting the results, the medical community must take into consideration the limitations and significant uncertainty of these approaches. In light of these findings, real cost-effectiveness analyses based on observed clinical outcomes appear to be more robust and reliable to assist decision-making, particularly in the context of RA.

Abstract
OBJECTIVE To evaluate in patients with knee osteoarthritis (OA) the size changes in bone oedema and cysts over 24 months, and to contrast these changes with cartilage volume loss using quantitative magnetic resonance imaging. METHODS 107 patients with knee OA, selected from a large trial evaluating the effect of a bisphosphonate, were analysed by magnetic resonance imaging at baseline and 24 months. Assessments of subchondral bone oedema and cysts, and cartilage volume were done. RESULTS At baseline, 86 patients showed the presence of at least one type of bone lesion: 71 oedema, 61 cysts and 51 both. At 24 months, although not statistically significant, the oedema total size change increased by 2.09 (SD 15.03) mm, and the cyst by 1.09 (8.13) mm; mean size change for the oedema was +0.38 (2.18) mm and -0.10 (4.36) mm for the cyst. When analysed according to subregions, an increase was found for the cyst size in the trochlea (+0.67 (2.74) mm, p = 0.02) and in the lateral tibial plateau (+0.15 (0.83) mm, p = 0.09), and for the oedema size in the medial tibial plateau (+1.73 (8.11) mm, p = 0.05). At 24 months, significant correlations were seen between the loss of cartilage volume and oedema size change in the medial condyle (-0.40, p = 0.0001) and the medial tibial plateau (-0.23, p = 0.03), and the changes in cyst size in the medial condyle (-0.29, p = 0.01). A multivariate analysis showed that the oedema size change was strongly and independently associated with medial cartilage volume loss (-0.31, p = 0.0004). CONCLUSION These data demonstrate that bone lesions are prevalent in knee OA. The correlation of the oedema and cyst size increase in the medial compartment over time with a greater loss of cartilage volume in this area underlines the importance of subchondral bone lesions in OA pathophysiology.

Abstract
Interstitial pneumonitis is a well documented, rare complication of methotrexate (MTX). We describe a patient with rheumatoid arthritis (RA) taking MTX for more than 3 years who then developed severe interstitial pneumonitis after a third infliximab infusion. Other similar cases are reviewed. Infliximab may potentiate pulmonary toxicity of MTX.

Abstract
OBJECTIVE To determine whether the need to use doses of infliximab greater than 3 mg/kg every 8 weeks to achieve or maintain clinical response in patients with rheumatoid arthritis (RA) is associated with differences in baseline clinical characteristics or anti-infliximab antibodies. METHODS Baseline clinical characteristics and anti-infliximab levels were evaluated retrospectively in a cohort of 51 consecutive patients with RA treated with infliximab at a single center. Patients were divided into 2 groups for comparison: Group 1 patients achieved and maintained clinical responses with infliximab 3 mg/kg every 8 weeks; Group 2 patients required higher doses. RESULTS Thirty-two (63%) patients required infliximab dose escalation (Group 2). There were no statistically significant differences in baseline or clinical characteristics between Group 1 and Group 2 patients. Anti-infliximab antibodies occurred in 47% of Group 2 versus 27% of Group 1 patients, with higher anti-infliximab antibody concentrations in Group 2 patients (mean +/- SD: 18.3 +/- 8.9 g/ml vs 7.5 +/- 4.8 g/ml; p = 0.02). Patients who developed anti-infliximab antibodies were younger and receiving less prednisone at the time of infliximab initiation than patients who did not. CONCLUSION Finding higher anti-infliximab antibody concentrations in patients who needed dose escalation of infliximab to achieve or maintain clinical responses with lower serum trough levels of infliximab suggests that development of anti-infliximab antibodies may reduce clinical efficacy of infliximab in some patients with RA.

Abstract
PURPOSE OF REVIEW The anti-tumor necrosis factor agents are now widely used in the management of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile inflammatory arthritis. One of the most common observations made during their use is the development of autoantibodies. The purpose of this paper is to review this phenomenon and its clinical implications. RECENT FINDINGS While the development of different autoantibodies is a common encounter, rare cases of lupus-like syndromes have been reported. On the other hand, a variety of immune-mediated clinical manifestations have been described, including vasculitis and demyelinating syndromes. Rare cases of cytopenia and non-specific lung injuries have also been reported. SUMMARY While these clinical complications are rare and isolated events, clinicians must be aware of their occurrence. The experience with the anti-tumor necrosis factor agents is rather short and new, unusual immune-mediated complications may still appear. Clinicians should be prepared to recognize them.

Abstract
The objective of this study was to further explore the cartilage volume changes in knee osteoarthritis (OA) over time using quantitative magnetic resonance imaging (qMRI). These were correlated with demographic, clinical, and radiological data to better identify the disease risk features. We selected 107 patients from a large trial (n = 1,232) evaluating the effect of a bisphosphonate on OA knees. The MRI acquisitions of the knee were done at baseline, 12, and 24 months. Cartilage volume from the global, medial, and lateral compartments was quantified. The changes were contrasted with clinical data and other MRI anatomical features. Knee OA cartilage volume losses were statistically significant compared to baseline values: -3.7 ± 3.0% for global cartilage and -5.5 ± 4.3% for the medial compartment at 12 months, and -5.7 ± 4.4% and -8.3 ± 6.5%, respectively, at 24 months. Three different populations were identified according to cartilage volume loss: fast (n = 11; -13.2%), intermediate (n = 48; -7.2%), and slow (n = 48; -2.3%) progressors. The predictors of fast progressors were the presence of severe meniscal extrusion (p = 0.001), severe medial tear (p = 0.005), medial and/or lateral bone edema (p = 0.03), high body mass index (p < 0.05, fast versus slow), weight (p < 0.05, fast versus slow) and age (p < 0.05 fast versus slow). The loss of cartilage volume was also slightly associated with less knee pain. No association was found with other Western Ontario McMaster Osteoarthritis Index (WOMAC) scores, joint space width, or urine biomarker levels. Meniscal damage and bone edema are closely associated with more cartilage volume loss. These data confirm the significant advantage of qMRI for reliably measuring knee structural changes at as early as 12 months, and for identifying risk factors associated with OA progression.

Abstract
The tumor necrosis factor inhibitors are a diverse group of biologic agents. Although there are no studies that directly compare these agents, data from noncomparative trials suggest that all 3 agents have therapeutic activity in rheumatoid arthritis. Etanercept and infliximab have also demonstrated beneficial activity in other inflammatory arthritides (ie, psoriatic arthritis and ankylosing spondylitis [both agents] and juvenile rheumatoid arthritis [etanercept only]) and inflammatory diseases (ie, psoriasis and uveitis). Their effects in granulomatous diseases are more variable, with only infliximab demonstrating clear efficacy in the treatment of Crohn's disease, sarcoidosis, and Wegener's granulomatosis. The purpose of this brief review is to summarize current efficacy data and explore possible explanations for observed clinical differences.

Abstract
Blockade of tumor necrosis factor (TNF) has emerged as one of the most promising therapies in rheumatoid arthritis (RA). Three agents are currently available as specific TNF antagonists, etanercept (Enbrel), infliximab (Remicade), and adalimumab (Humira). Data from noncomparative trials suggest that all 3 agents have comparable therapeutic activity in RA. Etanercept and infliximab have also demonstrated beneficial activity in other inflammatory arthritides [i.e., psoriatic arthritis and ankylosing spondylitis (both agents) and juvenile rheumatoid arthritis (etanercept only)] and inflammatory diseases (i.e., psoriasis and uveitis). Their effects in granulomatous diseases are more variable, with only infliximab demonstrating clear efficacy in the treatment of Crohn's disease, sarcoidosis, and Wegener's vasculitis. In this brief review current efficacy data are summarized and possible explanations for observed clinical differences are explored.

Abstract
Despite optimization of the use of the traditional disease modifying antirheumatic drugs (DMARD) as mono- or combination therapy, between 25% and 50% of patients with rheumatoid arthritis (RA) still have clinically active synovitis with progressive structural articular damage. Several clinical trials with the anti-tumor necrosis factor (TNF) agents etanercept, infliximab, and adalimumab, used alone or in combination with methotrexate, in patients with early or established RA have shown consistent improvement in signs and symptoms as well as function, with a dramatic slowing of radiographic damage. The anti-TNF agents combined with optimal doses of MTX currently constitute the best therapeutic regimen for the management of patients with RA failing to adequately respond to traditional DMARD.
