Objective: The evaluation of disease activity in obese rheumatoid arthritis (RA) patients presents challenges particularly in the clinical assessment of swollen joints. This study examines the effect of obesity on the American College of Rheumatology (ACR) core set measures used in assessing RA disease activity with specific focus on the swollen joint count (SJC).
Methods: We examined a cross-sectional cohort of 323 early seropositive RA patients (symptom duration ≤15 months).
Objective: To evaluate the effect of sustained American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) Boolean remission on residual joint inflammation assessed by magnetic resonance imaging (MRI) and to secondarily evaluate other clinical definitions of remission, within an early seropositive rheumatoid arthritis (RA) cohort.
Methods: A subcohort of 118 RA patients was enrolled from patients who completed the 2-year, double-blind randomized Treatment of Early Aggressive Rheumatoid Arthritis (TEAR) trial. Patients received a single contrast-enhanced 1.
Background: Controversy exists in understanding the effects of age at onset and comorbidities in predicting rheumatoid arthritis (RA) response to biologic therapy.
Objective: The objective of this study was to investigate the influence of age at onset and number of comorbidities on Health Assessment Questionnaire-Disability Index (HAQ-DI) and Clinical Disease Activity Index (CDAI) responses in active RA patients after 6 months of treatment with etanercept.
Methods: One thousand eight hundred ninety-nine RA patients were assessed after 6 months of etanercept therapy.
Statistical analysis plays a critical role in data interpretation in all fields and particularly so for clinical data where important treatment decisions are made. We provide here an in-depth and illustrative analysis to examine patterns and radiographic scores in an early disease rheumatoid arthritis cohort over a 3-year follow-up period. The total Sharp radiographic scores were interpolated from the rates at 6 months, 1, 2, and 3 years and were transformed to count data after rounding.

Methods: A subcohort of 1548 RA subjects with varying disease duration met the following inclusion criteria: started a DMARD/biologic agent, continued therapy ≥ 3 months, CDAI ≥ 2.8 at study entry and followed longitudinally from baseline to follow-up (mean time 7.
Objective: To study changes in lipid profiles at 24 weeks among patients with early rheumatoid arthritis (RA) participating in the Treatment of Early RA (TEAR) trial and randomized to receive methotrexate (MTX) plus etanercept, triple therapy (MTX plus sulfasalazine plus hydroxychloroquine), or aggressively titrated MTX monotherapy.
Methods: This TEAR substudy included 459 participants with biologic specimens. Serum levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol were measured at 0 and 24 weeks.
Evaluation of test characteristics for outcome measures used in Raynaud's phenomenon clinical trials.
Arthritis Care Res (Hoboken)

Objective: Randomized controlled trials (RCTs) in Raynaud's phenomenon (RP) have shown conflicting efficacy data. Also, there is no consensus on the outcome measures that should be used. Our objectives were to assess the reliability of individual core set measures used in 3 RCTs, evaluate the placebo response for individual core set measures, and determine if a composite of individual core set measures will decrease the placebo response, which may improve our ability to see treatment effects in future trials.

Lipid-lowering agents may be associated with myopathic side effects. The current work evaluates the use of lipid-lowering therapy in patients with IIM treated by IIM specialists belonging to the International Myositis Assessment and Clinical Studies (IMACS) Group.

Methods: The Treatment of Early Aggressive Rheumatoid Arthritis (TEAR) study is a 2-year, randomized, double-blind trial.
Objectives: Reverse cholesterol transport (RCT) is a major antiatherogenic function of high density lipoprotein (HDL). In the current work, the authors evaluated whether the RCT capacity of HDL from rheumatoid arthritis (RA) patients is impaired when compared to healthy controls.
Methods: HDL was isolated from 40 patients with RA and 40 age and sex matched healthy controls.
Patient overall satisfaction with health (PSH) was measured by a subset of questions from the Arthritis Impact Measurement Scales II. Based on longitudinal observations for 267 early rheumatoid arthritis (RA) patients of the United States Western Consortium (WC) cohort receiving first non-biologic DMARD treatment, we estimated the 1-year change in PSH (Δ PSH). Logistic regression analysis was used to estimate the association of improvement in Δ PSH with the core set of clinical and patient-reported components of disease activity scores (DAS).

Methods: Patients with polyarticular disease who were DMARD-naive and had seropositive early RA (< 14 months) were recruited by the Western Consortium of Practicing Rheumatologists. Each patient was examined at study entry, after 6 and 12 months, and yearly thereafter.
With advancing therapeutic options, achieving a state of remission has become the treatment goal in rheumatoid arthritis. Agreeing on what constitutes remission and what measures should be used to assess disease activity has remained a challenge. Multiple remission criteria have been devised and modified, all with different strengths and limitations.
View Article and Find Full Text PDFObjective: We previously observed the association of the co-occurrence of the HLA-DRB1 shared epitope (SE) and RANKL single-nucleotide polymorphisms (SNPs) with younger age at the onset of rheumatoid arthritis (RA) in 182 rheumatoid factor (RF)-positive European American patients with early-onset RA. The aim of this study was to fine-map the 48-kb RANKL region in the extended cohort of 210 European American RF-positive patients with early RA, to seek replication of RA-associated SNPs in additional RA cohorts of 501 European Americans and 298 African Americans, and to explore the functional consequences of RA-associated SNPs.
Methods: SNP genotyping was conducted using pyrosequencing or TaqMan polymerase chain reaction (PCR) assays.
Objective: To evaluate responses by time to initiation of nonbiologic disease-modifying antirheumatic drugs (DMARD) in a DMARD-naive cohort of patients with early seropositive rheumatoid arthritis (RA).
Methods: Subjects were categorized by the time from symptom onset to the first DMARD use (median 5.7 months, range 0.
Objective: To characterize the antiinflammatory function of high-density lipoprotein (HDL) in patients with rheumatoid arthritis (RA) and to identify specific differences in HDL-associated proteins and enzymes that distinguish proinflammatory HDL from normal, antiinflammatory HDL.
Methods: We studied 132 RA patients. The antiinflammatory function of HDL was assessed by a cell-free assay, and proinflammatory HDL was defined by an HDL inflammatory index > or =1.
Objective: New methodologies allow the scores for the Health Assessment Questionnaire-Disability Index (HAQ-DI) to be translated into preferences/utility scores. We evaluated the construct validity of the HAQ-DI-derived Short Form-6D (SF-6D) score and assessed its responsiveness to change over 6- and 12-month followup periods in patients with early aggressive rheumatoid arthritis (RA).
Methods: Patients (n=277) participating in an RA observational study completed self-reported measures of symptoms and the HAQ-DI at baseline and at 6 and 12 months.
Objective: We examined the relationships of rheumatoid arthritis (RA), disease duration (DD), number of previous disease modifying antirheumatic drugs (DMARD), and frequency of DMARD changes, with regard to changes in function in patients with RA evaluated by modified Health Assessment Questionnaire (mHAQ) after the start of a new DMARD.
Methods: In total, 889 patients with active RA from the CORRONA database [patients had mHAQ>or=0.5 and/or Disease Activity Score 28-joint count (DAS28)>or=1.
Objective: Patients with rheumatoid arthritis (RA) have a 2-3-fold increased risk of myocardial infarction. Recent work suggests that plasma high density lipoproteins (HDL) from patients with RA are more proinflammatory than HDL from controls. We examined the effects of atorvastatin 80 mg daily on the inflammatory properties of HDL and clinical disease activity in RA.

Methods: Disease-modifying anti-rheumatic drug-naïve RF+ patients (n = 223; mean duration of symptoms, 6 months) were categorised as ACR none/20/50/70 responders. One-way analysis of variance and two-sample t tests were used to investigate the relationship between the ACR response groups and each composite measure.
Objective: To evaluate the safety of etanercept in patients with rheumatoid arthritis (RA) and concomitant comorbidities.
Methods: The safety of etanercept (25 mg twice weekly) in RA patients with at least one comorbidity (i.e.
Objective: To evaluate published proposed definitions of minimal disease activity (MDA) and remission in patients with early rheumatoid arthritis (RA).
Methods: The cohort comprised disease-modifying antirheumatic drug (DMARD)-naive patients with early seropositive active RA (n = 200) treated with traditional DMARDs in the prebiologic era. MDA definitions included Disease Activity Score in 28 joints (DAS28)
