Nonsteroidal antiinflammatory drug withdrawal in patients with stable rheumatoid arthritis.

OBJECTIVE: To evaluate the effect of nonsteroidal antiinflammatory drug (NSAID) withdrawal on blood pressure (BP), 44-joint Disease Activity Score (DAS44), and functional assessments in patients with stable rheumatoid arthritis (RA). METHODS: NSAID was withdrawn from 30 patients with stable RA (DAS44 ≤ 2.8). Other prescribed medication continued. Clinical and laboratory measures were taken at baseline, 6 weeks, and 12 weeks. RESULTS: No participants required NSAID reintroduction during the study period. Significant improvement in systolic BP was noted: maximal median reduction was 7 mm Hg (baseline to 12 weeks). There was no significant deterioration in DAS44 or function. Eleven participants required additional intervention. CONCLUSION: NSAID withdrawal resulted in improvement in BP without loss of disease control.

Combination therapy with sulfasalazine and methotrexate is more effective than either drug alone in patients with rheumatoid arthritis with a suboptimal response to sulfasalazine: results from the double-blind placebo-controlled MASCOT study.

BACKGROUND: Optimal use of disease-modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis is vital if progression of disease is to be reduced. Methotrexate (MTX) and sulfasalazine (SASP) are widely used inexpensive DMARDs, recently often combined despite no firm evidence of benefit from previous studies. AIM: To establish whether a combination of SASP and MTX is superior to either drug alone in patients with rheumatoid arthritis with a suboptimal response to 6 months of SASP. METHODS: A randomised controlled study of step-up DMARD treatment in early rheumatoid arthritis. In phase I, 687 patients received SASP for 6 months. Those with a disease activity score (DAS) > or =2.4 were offered additional treatment in phase II (SASP alone, MTX alone or a combination of the two). The primary outcome measure was change in DAS. RESULTS: At 6 months, 191 (28%) patients had a DAS <2.4, 123 (18%) were eligible but did not wish to enter phase II, 130 (19%) stopped SASP because of reversible adverse events and 165 (24%) entered phase II. DAS at 18 months was significantly lower in those who received combination treatment compared with those who received either SASP or MTX: monotherapy arms did not differ. Improvement in European League Against Rheumatism and American College of Rheumatology 20, 50 and 70 scores favoured combination therapy. CONCLUSIONS: In this "true-to-life" study, an inexpensive combination of DMARDs proved more effective than monotherapy in patients with rheumatoid arthritis with a suboptimal response to SASP. There was no increase in toxicity. These results provide an evidence base for the use of this combination as a component of tight control strategies.

"5D" Outcome in 52 patients with rheumatoid arthritis surviving 20 years after initial disease modifying antirheumatic drug therapy.

OBJECTIVE: Evaluation of a complex and variable disease such as rheumatoid arthritis (RA) poses a challenge particularly over the medium to long term. A practical framework to evaluate clinically relevant outcomes over the long term is the "5D" approach of Fries, described in 1980. We describe the 20 year outcome in 52 survivors of a 123 patient cohort in terms of change in discomfort, disability, drug side effects, dollar costs, and deaths. METHODS: We studied 123 patients with RA allocated to their first disease modifying antirheumatic drug (DMARD) between 1977 and 1979. All were under the overall care of one physician over the 20 years and were maintained where possible taking a single DMARD. Baseline demographic variables, the Ritchie Articular Index (RAI), Lee functional index, and erythrocyte sedimentation rate (ESR) were initially recorded. The extent to which the demographic and disease variables contributed to need for joint replacement surgery was assessed. Therapies for comorbidity were also documented. RESULTS: At cohort inception mean age was 50 years, RAI was 35, and median disease duration 5.5 years. F:M ratio was 90:33; 96% of patients were positive for rheumatoid factor (RF). Initial median ESR was 55 mm/h. At 20 years, 9 patients (7% of original cohort, 14% of survivors) were lost to followup and 62 (50%) had died. In the 52 survivors RAI, a surrogate for disability, showed a significant improvement (p < 0.0001), but disability measured by Lee functional index showed a deterioration (p = 0.018); 50% underwent joint replacement surgery. Initial ESR and mean ESR over the first 10 years of followup were significantly higher in those who required surgery. Nonsteroidal antiinflammatory drug (NSAID) use declined, but at least 2 deaths and 4 renal deaths that may have been related to therapy were attributed to NSAID use. No unexpected DMARD toxicity or mortality occurred. Concomitant therapy for comorbidity, in particular for cardiovascular disease, osteoporosis, and gastrointestinal disease, increased: more than 60% were on these therapies at 20 year followup. CONCLUSION: Strategies to improve the outcome of RA in all dimensions should include: earlier referral for expert assessment; avoidance of NSAID gastrointestinal and nephrotoxicity; a more intensive effort to identify effective management of comorbidity and those likely to have a poor outcome. Such patients require sustained, intensive therapy to minimize later disability.
