Abstract
OBJECTIVE Our objective was to evaluate the factors associated with regional variation of rheumatoid arthritis (RA) disease burden in the US. METHODS In a retrospective cohort analysis of Rheumatology Informatics System for Effectiveness (RISE) registry data, seropositivity, RA disease activity (Clinical Disease Activity Index [CDAI], Routine Assessment of Patient Index Data-version 3 [RAPID3]), socioeconomic status (SES), geographic region, health insurance type, and comorbidity burden were recorded. An Area Deprivation Index score of more than 80 defined low SES. Median travel distance to practice sites' zip codes was calculated. Linear regression was used to analyze associations between RA disease activity and comorbidity adjusting for age, sex, geographic region, race, and insurance type. RESULTS Enrollment data for 184,722 patients with RA from 182 RISE sites were analyzed. Disease activity was higher in African American patients, in those from Southern regions, and in those with Medicaid or Medicare coverage. Greater comorbidity was prevalent in patients in the South and those with Medicare or Medicaid coverage. There was moderate correlation between comorbidity and disease activity (Pearson coefficient: RAPID3 0.28, CDAI 0.15). High-deprivation areas were mainly in the South. Less than 10% of all participating practices cared for more than 50% of all Medicaid recipients. Patients living more than 200 miles away from specialist care were located mainly in Southern and Western regions. CONCLUSION A disproportionately large portion of socially deprived, high comorbidity, and Medicaid-covered patients with RA were cared for by a minority of rheumatology practices. Studies are needed in high-deprivation areas to establish more equitable distribution of specialty care for patients with RA.

Abstract
Objective A treat‐to‐target (TTT) approach improves outcomes in rheumatoid arthritis (RA). In prior work, we found that a learning collaborative (LC) program improved implementation of TTT. We conducted a shorter virtual LC to assess the feasibility and effectiveness of this model for quality improvement and to assess TTT during virtual visits. Methods We tested a 6‐month virtual LC in ambulatory care. The LC was conducted during the 2020–2021 COVID‐19 pandemic when many patient visits were conducted virtually. All LC meetings used videoconferencing and a website to share data. The LC comprised a 6‐hour kickoff session and 6 monthly webinars. The LC discussed TTT in RA, its rationale, and rapid cycle improvement as a method for implementing TTT. Practices provided de‐identified patient visit data. Monthly webinars reinforced topics and demonstrated data on TTT adherence. This was measured as the percentage of TTT processes completed. We compared TTT adherence between in‐person visits versus virtual visits. Results Eighteen sites participated in the LC, representing 45 rheumatology clinicians. Sites inputted data on 1,826 patient visits, 78% of which were conducted in‐person and 22% of which were held in a virtual setting. Adherence with TTT improved from a mean of 51% at baseline to 84% at month 6 (P for trend < 0.001). Each aspect of TTT also improved. Adherence with TTT during virtual visits was lower (65%) than during in‐person visits (79%) (P < 0.0001). Conclusion Implementation of TTT for RA can be improved through a relatively low‐cost virtual LC. This improvement in TTT implementation was observed despite the COVID‐19 pandemic, but we did observe differences in TTT adherence between in‐person visits and virtual visits.

Abstract
Background Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We examined the degree to which Patient Global Assessment of Disease Activity (PtGA) was driven by patient-reported assessments of pain (Pain), physical function, and fatigue in patients receiving tofacitinib 5 mg twice daily or placebo, each with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). Methods This post hoc analysis used data pooled from three randomized controlled trials in csDMARD-inadequate responder (csDMARD-IR) patients (ORAL Scan: NCT00847613; ORAL Standard: NCT00853385; ORAL Sync: NCT00856544). Using subgroup analysis from 2 × 2 tables, associations between PtGA and Pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at month 3 were evaluated using Pearson’s Phi correlation coefficients. To support the main analysis, associations between select patient-reported outcomes (PROs) were also evaluated in csDMARD-naïve (ORAL Start; NCT01039688) and biologic (b)DMARD-IR (ORAL Step; NCT00960440) patients. Results Across csDMARD-IR treatment groups, low disease activity (defined as PtGA ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in PtGA were associated with mild Pain (Visual Analog Scale score ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in Pain; lack of Pain improvement was associated with little/no improvement in PtGA. In contrast, large proportions of csDMARD-IR patients who reported PtGA improvements did not report HAQ-DI or FACIT-F scores ≥ normative values (≤ 0.25 and ≥ 43.5, respectively) or changes in HAQ-DI or FACIT-F scores ≥ minimum clinically important difference (≥ 0.22 and ≥ 4.0, respectively). Generally, PtGA and Pain outcomes were moderately-to-strongly correlated at month 3 in csDMARD-IR patients, with weaker correlations evident between PtGA and HAQ-DI/FACIT-F outcomes. Similar findings were generally evident in csDMARD-naïve and bDMARD-IR patients. Conclusions This analysis supports the role of Pain as a key driver of PtGA in RA; physical function and fatigue play lesser roles in patients’ perceptions of disease activity. These findings corroborate the importance of improved PROs and attainment of low symptom states for optimizing patient care.

Abstract
Background:Evaluation of early response to rheumatoid arthritis (RA) therapy at 12 weeks after initiation is recommended in treatment guidelines. C-reactive protein (CRP) response at 12 weeks on therapy may indicate favorable longer-term patient-reported outcomes (PROs).Objectives:To describe the association between CRP response at Week 12 and PROs at Week 24 with sarilumab therapy across three pivotal studies.Methods:The analysis included patients with RA who took part in MOBILITY (NCT01061736), TARGET (NCT01709578), or MONARCH (NCT02332590) and were treated with sarilumab 200 mg every 2 weeks (q2w) or adalimumab 40 mg q2w (MONARCH only). Patients who achieved a CRP response at Week 12 (defined as serum CRP ≤3 mg/L) were evaluated for PROs at Week 24. Response for PROs was defined as change from baseline visual analog scale score ≥10 for pain, sleep, and morning stiffness and an increase of ≥4 for FACIT-Fatigue score. Odds ratios (ORs) and 95% confidence intervals (CIs) were generated for the likelihood of achieving PRO responses at Week 24.Results:The proportions of patients achieving a CRP response at Week 12 were 78% (MOBILITY), 74% (TARGET), 80% (MONARCH, sarilumab), and 36% (MONARCH, adalimumab). Of these, 71.4% (MOBILITY; OR 3.78, 95% CI 2.31–6.18), 71.5% (TARGET; OR 2.86, 95% CI 1.44–5.65), 79.7% (MONARCH, sarilumab; OR 4.40, 95% CI 2.04–9.47), and 79.7% (MONARCH, adalimumab; OR 2.76, 95% CI 1.36–5.61) reported pain score responses at Week 24. Fatigue responses at Week 24 among Week 12 CRP responders were 66.6% (MOBILITY; OR 2.74, 95% CI 1.69–4.45), 59.9% (TARGET; OR 3.18, 95% CI 1.58–6.42), 73.0% (MONARCH, sarilumab; OR 4.78, 95% CI 2.21–10.33), and 64.1% (MONARCH, adalimumab; OR 1.64, 95% CI 0.88–3.06). Sleep was evaluated in MOBILITY only, and 58.2% of those achieving Week 12 CRP responses reported sleep score responses at Week 24 (OR 3.51, 95% CI 2.10–5.87). Morning stiffness responses (evaluated in TARGET and MONARCH only) at Week 24 among patients with Week 12 CRP responses were 71.5% (TARGET; OR 3.70, 95% CI 1.86–7.39), 81.1% (MONARCH, sarilumab; OR 5.36, 95% CI 2.47–11.63), and 75.0% (MONARCH, adalimumab; OR 2.42, 95% CI 1.24–4.72).Conclusion:Achievement of a CRP response at Week 12 in patients with RA treated with sarilumab 200 mg q2w or adalimumab 40 mg q2w was associated with improvements at Week 24 in PROs for pain, fatigue, sleep, and morning stiffness. Among patients with RA, CRP responses at 12 weeks on treatment predict favorable longer-term PRO improvements.Acknowledgments:Study funding was provided by Sanofi Genzyme (Cambridge, USA) and Regeneron Pharmaceuticals, Inc.

Abstract
Axial spondyloarthritis (axSpA) is a chronic inflammatory immune-mediated disease resulting in inflammatory low back pain and other inflammatory manifestations in peripheral joints and entheses. AxSpA encompasses both ankylosing spondylitis (AS), in which patients present with definitive sacroiliitis visible on radiographic imaging, as well as nonradiographic axSpA (nr-axSpA), in which such changes may not be discernable. Emerging evidence suggests that women and men experience axSpA differently. Although the prevalence of AS is approximately 2- to 3- fold higher in men than in women, nr-axSpA occurs with roughly equal frequency in women and men. The goal of this review is to increase awareness of sex differences in axSpA by exploring the distinct manifestations of disease and disease characteristics in women, the overall clinical burden, recommendations for diagnosis, and potential treatment options. We summarize and contextualize the results of recent studies that illuminate sex differences in nr-axSpA and AS, including differences in disease manifestation and progression. It is important that sex differences in axSpA are understood and considered when diagnosing and treating the spectrum of axSpA, including AS and nr-axSpA.

Abstract
BACKGROUND Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We performed a comprehensive review of phase 3 studies of tofacitinib 5 mg twice daily (BID) (approved dose in many countries) in patients with moderate to severe RA and inadequate response to prior disease-modifying antirheumatic drugs. METHODS A search of PubMed and ClinicalTrials.gov identified 5 studies: ORAL Solo (NCT00814307), ORAL Sync (NCT00856544), ORAL Standard (included adalimumab 40 mg once every 2 weeks; NCT00853385), ORAL Scan (NCT00847613), and ORAL Step (NCT00960440). Efficacy and safety data for tofacitinib 5 mg BID, placebo, and adalimumab were analyzed. RESULTS Across the 5 studies, 1216 patients received tofacitinib 5 mg BID, 681 received placebo, and 204 received adalimumab. At month 3, tofacitinib demonstrated significantly higher 20%, 50%, and 70% improvement in American College of Rheumatology response criteria (ACR20, ACR50, and ACR70, respectively) response rates, greater improvement in Health Assessment Questionnaire-Disability Index, and a higher proportion of Disease Activity Score-defined remission than placebo. Frequencies of adverse events (AEs), serious AEs, and discontinuations due to AEs were similar for tofacitinib and placebo at month 3; serious infection events were more frequent for tofacitinib. In ORAL Standard, although not powered for formal comparisons, tofacitinib and adalimumab had numerically similar efficacy and AEs; serious AEs and serious infection events were more frequent with tofacitinib. CONCLUSIONS Tofacitinib 5 mg BID reduced RA signs and symptoms and improved physical function versus placebo in patients with inadequate response to prior disease-modifying antirheumatic drugs. Tofacitinib 5 mg BID had a consistent, manageable safety profile across studies, with no new safety signals identified.

Abstract
BACKGROUND Psoriatic arthritis (PsA) is associated with multiple comorbid conditions, including cardiovascular (CV) comorbidities that impose a considerable burden on patients. Effective management of PsA requires an understanding of comorbidity profiles. OBJECTIVE To compare the frequency and incidence rates of comorbidities and hospitalizations among newly diagnosed PsA patients and a matched general population without PsA, using large national claims databases in the United States. METHODS This retrospective observational study used MarketScan databases from January 1, 2008, to September 30, 2015, to identify adult patients with newly diagnosed PsA (i.e., no PsA diagnosis during the 1 year before the first observed PsA diagnosis). The earliest date of PsA diagnosis was defined as the index date. Patients with no PsA diagnosis any time during the study period (controls) were directly matched to PsA patients with demographic characteristics. All patients had ≥ 2 years of medical and pharmacy coverage before the index date and ≥ 1 year of follow-up. Incident rates per 100 person-years for comorbidities of interest were evaluated. The hazard ratios of having various comorbid conditions for PsA patients were estimated by Cox proportional hazards models. All-cause and CV-related hospitalizations during the follow-up period were evaluated. RESULTS A total of 14,898 PsA patients and 35,037 matched controls met the study criteria. Compared with controls, PsA patients had a higher risk of CV disorders (incidence rate = 6.5 vs. 5.8; HR = 1.46; 95% CI = 1.37-1.56) and a higher risk of the majority of the specific CV disorders (hypertension, hyperlipidemia, coronary artery disease, cerebrovascular disease, peripheral vascular disease). PsA patients also had a higher risk for any autoimmune disease (incidence rate = 8.4 vs. 1.6; HR = 18.26; 95% CI = 17.18-19.40) and most autoimmune categories (psoriasis, ankylosing spondylitis, rheumatoid arthritis, multiple sclerosis, and other autoimmune disorders). Rates of other PsA-related comorbidities (diabetes, anxiety, fatigue, smoking, alcohol use, obesity or overweight, depression, osteoporosis, uveitis, eczema, and gout) were also significantly higher for PsA patients. The all-cause hospitalization rate was higher among PsA patients than controls (24.9% vs. 16.2%; P < 0.001). The CV-related hospitalization rate varied depending on whether the CV condition was the primary discharge diagnosis only or was any diagnosis on the inpatient claims. The rates of coronary artery disease hospitalizations were significantly higher in PsA patients than in controls with both methods of analysis (primary diagnosis: 0.8% vs. 0.5%; P < 0.001; nonprimary diagnosis: 3.2% vs. 2.2%; P < 0.001). CONCLUSIONS This retrospective U.S.-based claims study found that PsA patients had a high comorbidity burden. Compared with the non-PsA population, PsA patients were associated with a higher incidence of CV comorbidities, autoimmune diseases, and other PsA-related comorbidities and a higher rate of all-cause and CV-related hospitalizations. Understanding these comorbidity profiles may provide insight on the effect of comorbid conditions on disease management and health care utilization associated with PsA.

Abstract
Objective To investigate the safety of long-term subcutaneous (SC) abatacept treatment using integrated clinical trial data obtained in patients with rheumatoid arthritis refractory to traditional disease-modifying antirheumatic drugs. Methods Data from the double-blind and open-label phases of 5 clinical trials of SC abatacept were pooled. The overall and 6-month incidence rates were calculated as events per 100 patient-years of exposure. Results This analysis included 1,879 patients with 4,214.6 patient-years of exposure to SC abatacept. The mean ± SD length of exposure was 27.3 ± 9.1 months. The reported incidence rate of serious infections was 1.79 (95% confidence interval [95% CI] 1.42–2.24); the most frequent infections were pneumonia (incidence rate 0.36 [95% CI 0.22–0.59]), urinary tract infection (incidence rate 0.14 [95% CI 0.06–0.32]), and gastroenteritis (incidence rate 0.10 [95% CI 0.04–0.25]). Tuberculosis occurred rarely (incidence rate 0.09 [95% CI 0.04–0.25]). The reported incidence rate of malignancies was 1.32 (95% CI 1.01–1.72), and the most common was solid organ malignancy (incidence rate 0.69 [95% CI 0.48–0.99]). The incidence rate of autoimmune events was 1.37 (95% CI 1.06–1.78), and the most frequent events were psoriasis (incidence rate 0.33 [95% CI 0.20–0.56]) and Sjögren's syndrome (incidence rate 0.24 [95% CI 0.13–0.44]). The reported incidence rate of local injection site reactions was 1.72 (95% CI 1.36–2.17); these events occurred primarily during the first 6 months of treatment, and almost all were of mild or moderate intensity. The incidence rates of serious infections, malignancies, autoimmune events, and injection site reactions did not increase over time. Conclusion Long-term treatment with SC abatacept was associated with low incidence rates of serious infections, malignancies, and autoimmune events and was well tolerated, with infrequent injection site reactions. These findings are consistent with those related to treatment with intravenous abatacept. Long-term treatment with SC abatacept did not lead to new safety signals over time.

Abstract
Objective To examine the imaging-detected mechanism of reduction of structural joint damage progression by tocilizumab (TCZ) in patients with rheumatoid arthritis (RA) using MRI. Methods In a substudy of a randomised, double-blind, phase 3b study (ACT-RAY) of biologic-naïve patients with RA who were methotrexate (MTX)-inadequate responders, 63 patients were randomised to continue MTX or receive placebo (PBO), both in combination with TCZ 8 mg/kg every 4 weeks, with optional additional disease-modifying antirheumatic drugs at week 24 if Disease Activity Score of 28 joints < 3.2. The most symptomatic hand was imaged with 0.2 Tesla extremity MRI at weeks 0, 2, 12 and 52. MR images were scored using Outcome Measures in Rheumatology–Rheumatoid Arthritis Magnetic Resonance Imaging Score. Predictors of week 52 erosion progression were determined by logistic regression analysis. Results TCZ + PBO (n=32) demonstrated mean improvements in synovitis from baseline to weeks 2 (−0.92; p=0.0011), 12 (−1.86; p<0.0001) and 52 (−3.35; p<0.0001), while TCZ + MTX (n=31) had mean improvements in synovitis at week 12 (−0.88; p=0.0074), but not week 52 (−1.00; p=0.0711). TCZ+PBO demonstrated mean reductions in osteitis at weeks 12 (−5.10; p=0.0022) and 52 (−8.56; p=0.0006), while TCZ+MTX had mean reductions at weeks 2 (−0.21; p<0.05) and 12 (−3.63; p=0.0008), but not week 52 (−2.31; p=0.9749). Mean erosion scores did not worsen in either group. MRI erosion scores at weeks 12 and 52 correlated strongly with radiography erosion scores at week 52 (r>0.80). Baseline synovitis and worsening of osteitis predicted erosion progression. Conclusions Rapid suppression of synovitis and osteitis with reduction in structural joint damage progression occurred with TCZ, as monotherapy or in combination with MTX, through week 52.

Abstract
OBJECTIVES To assess the effect of a temporary interruption in subcutaneous (SC) abatacept on immunogenicity, safety and efficacy in patients with active rheumatoid arthritis despite methotrexate in a phase III trial. METHODS Following a 12-week open-label introduction (period I; intravenous abatacept loading dose and weekly fixed-dose SC abatacept 125 mg), patients were randomised 2:1 to double-blind SC placebo or SC abatacept for 12 weeks (period II). At the end of period II, patients receiving SC abatacept continued treatment and patients on placebo were reintroduced to SC abatacept (12-week open-label period III). The co-primary end points were ELISA-detected immunogenicity rate and safety at the end of period II. Efficacy was also monitored. RESULTS Of 167 patients entering period I, 72% qualified for period II; during periods II and III, three patients discontinued treatment. Mean (SD) disease duration was 6.6 (6.5) years and Disease Activity Score 28 was 4.8 (0.8). The primary end point was met, with a non-significant increase in immunogenicity upon withdrawal (7/73 placebo vs 0/38 abatacept in period II; p=0.119) which was reversed upon reintroduction of SC abatacept (2/73 vs 1/38, end period III). Safety was comparable regardless of withdrawal, with no unexpected events upon reintroduction. Two patients experienced reactions at the SC injection site. On withdrawal, patients experienced slight worsening in efficacy which improved following reintroduction. CONCLUSIONS Overall immunogenicity to SC abatacept is low, consistent with intravenous abatacept, and is not significantly affected by a 3-month interruption and reintroduction. This stop-start schedule was well tolerated, with little impact on safety and efficacy. These are important considerations for the clinical use of SC abatacept.

Abstract
OBJECTIVE To assess the efficacy, safety, and optimal dose of tacrolimus monotherapy in patients with rheumatoid arthritis (RA). METHODS This phase II, randomized, double-blind, placebo-controlled monotherapy study was set in 12 community sites and 9 university-based sites. Two hundred sixty-eight patients with RA who were resistant to or intolerant of methotrexate (mean dose 15.2 mg/week) and had active disease for at least 6 months (mean tender joint count 28.2, mean erythrocyte sedimentation rate 46.5 mm/hour) were randomized to receive treatment after discontinuation of methotrexate. Those who received at least 1 dose of tacrolimus were analyzed; 141 completed the study. Stable dosages of nonsteroidal antiinflammatory drugs and low-dose prednisone were allowed during treatment. All patients were given 1, 3, or 5 mg of tacrolimus or placebo once daily for 24 weeks. The American College of Rheumatology definition of 20% improvement (ACR20) and the tender and swollen joint counts at the end of treatment were the primary outcomes. RESULTS ACR20 response rates demonstrated a clear dose response. The ACR20 response was observed in 15.5% of patients receiving placebo (95% confidence interval [95% CI] 7.1-23.9%), 29% of the 1 mg tacrolimus group (95% CI 18.3-39.7%) (P < 0.058); 34.4% of the 3 mg group (95% CI 22.7-46.0%) (P < 0.013), and 50% of the 5 mg group (95% CI 37.8-62.3%) (P < or = 0.001). The tender joint count improved statistically significantly in all tacrolimus groups. The swollen joint count, physical function, and patient-assessed pain improved statistically significantly in the 3 mg and 5 mg groups. The incidence of creatinine elevation > or =40% above baseline levels increased in a dose-dependent manner. Dropout rates were high (41-59%) and were more common for inefficacy in the placebo patients (71.4%), whereas they were more common for toxicity in the high-dose tacrolimus groups (31-33%). Discontinuation for creatinine elevation occurred in the 3 mg (3.1%) and 5 mg (10.9%) tacrolimus groups. CONCLUSION Tacrolimus improved disease activity in methotrexate-resistant or -intolerant patients with RA. A dose response was observed when efficacy and toxicity were assessed at different doses. The optimal dose of tacrolimus appears to be >1 mg but < or=3 mg daily.

Abstract
OBJECTIVE Three 6-12-month, double-blind, randomized, controlled trials have shown leflunomide (LEF; 20 mg/day, loading dose 100 mg x 3 days) to be effective and safe for the treatment of rheumatoid arthritis (RA). This analysis of the North American trial assessed whether the clinical benefit evident at month 12 was sustained over 24 months of treatment with LEF as compared with the efficacy and safety of methotrexate (MTX), an equivalent disease-modifying antirheumatic drug, at 24 months. METHODS The year-2 cohort, comprising patients continuing into the second year of treatment with > or = 1 dose of study medication and > or = 1 followup visit after week 52, consisted of 235 patients (LEF n = 98; placebo n = 36; MTX n = 101). The mean (+/- SD) maintenance dose of LEF was 19.6 +/- 1.99 mg/day in year 2 and that of MTX was 12.6 +/- 4.69 mg/week. Statistical analyses used an intent-to-treat (ITT) approach. Statistical comparisons of the active treatments only were prospectively defined in the protocol. RESULTS In total, 85% and 79% of LEF and MTX patients, respectively, who entered year 2 completed 24 months of treatment. From month 12 to month 24, the American College of Rheumatology improvement response rates of > or = 20% (LEF 79% versus MTX 67%; P = 0.049), > or = 50% (LEF 56% versus MTX 43%; P = 0.053), and > or = 70% (LEF 26% versus MTX 20%; P = 0.361) were sustained in both of the active treatment groups. The mean change in total Sharp radiologic damage scores at year 2 compared with year 1 and baseline (LEF 1.6 versus MTX 1.2) showed statistically equivalent sustained retardation of radiographic progression in the active treatment groups. Maximal improvements evident at 6 months in the Health Assessment Questionnaire (HAQ) disability index (HAQ DI) and the physical component score of the Medical Outcomes Survey 36-item short form were sustained over 12 months and 24 months; improvement in the HAQ DI with LEF4(-0.60) was statistically significantly superior to that with MTX (-0.37) at 24 months (P = 0.005). Over 24 months in the ITT cohort, serious treatment-related adverse events were reported in 1.6% of the LEF-treated patients and 3.7% of the MTX-treated patients. Frequently reported adverse events included upper respiratory tract infections, diarrhea, nausea and vomiting, rash, reversible alopecia, and transient liver enzyme elevations. CONCLUSION The safety and efficacy of LEF and MTX were maintained over the second year of this 2-year trial. Both active treatments retarded radiographic progression over 24 months. LEF was statistically significantly superior to MTX in improving physical function as measured by the HAQ DI over 24 months of treatment. Results indicate that LEF is a safe and effective initial treatment for active RA, with clinical benefit sustained over 2 years of treatment without evidence of new or increased toxicity.

Abstract
GOALS To evaluate the efficacy and gastrointestinal safety of nabumetone and diclofenac in the treatment of elderly patients with osteoarthritis, participating in a 3-month efficacy trial. BACKGROUND Elderly patients have an elevated risk for developing gastrointestinal complications with chronic use of nonsteroidal anti-inflammatory drugs. STUDY This was a randomized, double-blind, parallel-group, multicenter study with a 3-to 14-day placebo washout period and a 12-week active treatment phase. Patients 65 years or older with moderate-to-severe osteoarthritis of the knee or hip were randomized to receive 1,000 to 2,000 mg/d of nabumetone or 100 to 150 mg/d of diclofenac. The primary efficacy parameters were the percent of patients improved using a Patients' and Physicians' Global Assessment at endpoint. Gastrointestinal safety was assessed by the incidence of gastrointestinal symptoms and adverse events. RESULTS Three hundred thirty-five patients (mean age = 72 years) with active osteoarthritis were enrolled. There were no statistically significant differences between the two treatment groups in any of the primary efficacy variables. However, differences between the groups were apparent in the frequency of adverse gastrointestinal events. Two patients in the diclofenac group had evidence of gastrointestinal bleeding and/or ulcer compared with none in the nabumetone group. In addition, significantly more (p < 0.05) patients (4%) receiving diclofenac had alanine transaminase values more than twice the upper limit of normal at endpoint compared with patients receiving nabumetone (0%). CONCLUSIONS Nabumetone was as effective as diclofenac in the treatment of elderly patients with moderate-to-severe osteoarthritis. However, the gastrointestinal safety profile of nabumetone was superior to that of diclofenac with respect to elevation of liver enzymes.

Abstract
CONTEXT Leflunomide is a reversible inhibitor of de novo pyrimidine synthesis shown to be effective in a phase 2 trial in 402 patients with active rheumatoid arthritis (RA). OBJECTIVE To compare the efficacy and safety of leflunomide treatment with placebo and methotrexate treatment in patients with active RA. DESIGN Randomized, double-blind, placebo, and active-controlled 12-month study. SETTING Forty-seven university and private rheumatology practices in the United States and Canada. PATIENTS Diagnosis of RA by the American College of Rheumatology (ACR) criteria for duration of 6 months or longer and no previous methotrexate treatment. INTERVENTION Leflunomide treatment (20 mg/d), placebo, or methotrexate treatment (7.5-15 mg/wk). MAIN OUTCOME MEASURES American College of Rheumatology success rate (completed 52 weeks of treatment and met the ACR > or = 20% response criteria), disease progression as assessed by x-ray films, and improvement in function and health-related quality of life using the intent-to-treat population. RESULTS The 482 patients studied were predominantly women (mean age, 54 years; mean disease duration, 6.7 years) for whom a mean of 0.8 disease-modifying antirheumatic drugs had failed. The ACR response and success rates for patients receiving leflunomide treatment (52% and 41%, respectively) and methotrexate treatment (46% and 35%, respectively) were significantly higher than those for patients receiving placebo (26% and 19%, respectively) (P<.001), and they were statistically equivalent, with mean time to initial response at 8.4 weeks for patients receiving leflunomide vs 9.5 weeks for patients receiving methotrexate therapy. X-ray analyses demonstrated less disease progression with leflunomide (P=.001) and methotrexate (P = .02) therapy than with placebo. Leflunomide and methotrexate treatment improved measures of physical function and health-related quality of life significantly more than placebo (P<.001 and P<.05, respectively). Common adverse events for patients receiving leflunomide treatment included gastrointestinal complaints, skin rash, and reversible alopecia. Asymptomatic transaminase elevations resulted in treatment discontinuations for 7.1% of patients receiving leflunomide therapy, 1.7% of patients receiving placebo, and 3.3% of patients receiving methotrexate therapy. CONCLUSIONS Clinical responses following administration of leflunomide, a new therapeutic agent for the treatment of RA, were statistically superior to those with placebo and equivalent to those with methotrexate treatment. Both active treatments improved signs and symptoms of active RA, delayed disease progression as demonstrated by x-ray films, and improved function and health-related quality of life.

Abstract
Indirect immunofluorescence with monoclonal antibodies to 6 different idiotypes was used to characterize immunoglobulins deposited in the glomeruli of renal biopsy samples from 32 patients with systemic lupus erythematosus (SLE) and 19 patients with nonlupus immune glomerulonephritis. IdGN2 was present in 75% of the biopsy specimens from SLE patients and in 6% of those from patients with non-lupus nephritis; IdGN1 occurred in 38% and 6%, respectively. The other idiotypes were not increased in biopsy samples from patients with SLE. Deposition of IdGN2 was associated with a subendothelial location of Ig and proliferative changes in the glomeruli. In studies of glomerular eluates from 4 immunosuppressed SLE patients, an average of 26% of total Ig and 37% of anti-DNA was composed of IdGN2. Compared with IdGN2- immunoglobulin, IdGN2+ immunoglobulin was enriched in IgG1 in all 4 eluates, and was enriched in high-avidity anti-DNA in 2 eluates. IdGN2 is a marker of antibody subsets that are characteristic of SLE and are associated with severe lupus nephritis.

Abstract
A new hereditary syndrome characterized by a frontoparietal lobe pseudotumor and retinal capillary abnormalities is described. A pedigree is presented in which characteristic ophthalmic findings have been found in ten family members and are suspected in eight additional family members spanning a total of four generations. Typical retinal findings include perifoveal capillary obliteration, peripheral focal capillary occlusion, and microvascular abnormalities, particularly involving the posterior pole. Eight patients spanning three generations had a central nervous system pseudotumor with identical histopathology. Histopathologic analysis of brain tissue shows a characteristic pattern of an unusual vasculopathy without vasculitis characterized by fibrinoid necrosis and resulting in necrosis of white matter with sparing of cortical brain tissue. The pedigree shows an apparent autosomal dominant pattern of inheritance with delayed expression of abnormalities. Of note, two patients unrelated to the pedigree having similar neuropathologic and retinal findings also have been seen at the authors' institution.
