Abstract: AIMS: To describe the utilization of combination therapy in the treatment of rheumatoid arthritis (RA). METHODS: Review of published articles and abstracts, and patient/physician questionnaire data. RESULTS: Combination therapy was rarely used in the early 1980s and is now (1999) used for about 25% of RA patients in the US. Physician and patient surveys indicate that methotrexate plus hydroxychloroquine is the most commonly used combination in North America, and physician surveys indicate that methotrexate plus sulfasalazine is the most commonly used combination in Europe. Patient questionnaire data indicate that 13.4% of patients in the US take methotrexate and hydroxychloroquine, and between 11% and 15% of patients with recent onset of RA receive treatment with disease-modifying antirheumatic drug (DMARD) combinations. CONCLUSIONS: Combination therapy with agents such as hydroxychloroquine and methotrexate is used in up to 25% of RA patients in the US, but the use of "aggressive combination therapy" is unusual. Whether combination therapy as currently practiced is beneficial remains to be determined.

Abstract: OBJECTIVE: To examine the nature of seasonal symptoms, their prevalence, and differences among rheumatic disorders by examining longitudinal data over a period of up to 24 years. METHODS: We used a questionnaire assessment of seasonal symptoms using the Seasonal Pattern Assessment Questionnaire (SPAQ) in 1,424 patients with rheumatoid arthritis (RA), osteoarthritis (OA), and fibromyalgia (FM). Clinical status was evaluated with standard assessment measures, and reported symptoms were compared with actual seasonal differences measured for periods of up to 24 years. RESULTS: About 50% of patients with rheumatic disease reported exacerbation of rheumatic symptoms (pain, global severity, and fatigue) by seasonal changes. The presence of seasonal symptoms was not related to diagnosis or to seasonal affective disorder (SAD) symptoms, and symptoms were less common in older patients and in men. The number of symptoms and the severity of allied factors (depression, anxiety, pain, global severity, number of months with seasonal symptoms) were increased in persons with FM and/or complete SAD symptoms. Using circular statistics, the modal months for worse symptoms were December and January, and for best symptoms was July. Bimodal patterns of seasonality were identified for global severity, joint pain, fatigue, and socialization. Seasonal symptoms differed as to the degree at which they were dispersed around the 12 month circle. When pain and global severity measurements obtained over a 24 year period were analyzed, pain was slightly increased in the summer and global severity was not related to season at all. Even when patients who specifically reported worse symptoms in winter and best symptoms in summer were examined, no effect of season could be found. CONCLUSION: Seasonal rheumatic symptoms are commonly reported across all rheumatic diseases, but appear to reflect perception rather than reality since reported symptoms do not agree with measured clinical scores. In addition, regardless of seasonal complaints, measured pain and global severity scores are not worse in winter. Although patients with FM and Season (+) patients report more severe symptoms, their pattern of reporting and their actual scores do not differ according to season compared to persons without FM or positive seasonality.

Abstract: OBJECTIVE: It has been suggested that rheumatoid arthritis (RA) itself may be a risk factor for adverse gastrointestinal (GI) events, but this hypothesis has not been studied in a large sample, nor has the effect of time on risk factors been studied. We investigated rates and risk factors for GI events in RA and osteoarthritis (OA) and assessed the additional risks conveyed by having RA. METHODS: A prospective study of patients with OA and RA from a single center was undertaken using questionnaires mailed at 6 month intervals. The relationship between drug therapy and GI events was assessed in the same 6 month time frame. Over 13 years of biannual assessments, 2,131 patients were studied for serious GI events and adverse GI symptoms during 9,621 patient-years of observation. RESULTS: The incidence rate (IR) for GI hospitalization was 1.56 and 1.28 per 100 patient-years, and for GI bleeding or perforation was 0.50 and 0.58 for RA and OA, respectively. After controlling for age, sex, nonsteroidal antiinflammatory drug (NSAID) and steroid use, the incidence rate ratio (IRR) for RA versus OA did not differ for hospitalization [IRR 1.07 (95% CI 0.66, 1.74)] or for bleeding or perforation [IRR 0.63 (95% CI 0.29, 1.35)]. In multivariate analyses for both groups combined, the IRR was 2.95 (2.05, 4.24) for prednisone use, 1.41 (1.08, 1.85) for NSAID use, and 1.46 (1.22, 1.74) for every 10 year increase in age. In additional multivariate models, Health Assessment Questionnaire disability was also a significant risk factor. During the study period, the odds of NSAID use decreased 2.94 times per 10 year period, while the odds of prednisone use increased by 1.49. Dysphagia [IRR 1.11 (1.00, 1.24)], anorexia [IRR 1.13 (1.03, 1.23)], nausea [IRR 1.13 (1.04, 1.25)], heartburn [IRR 1.12 (1.05, 1.19)], vomiting [IRR 1.20 (1.02, 1.42)], peptic ulcer symptoms [IRR 1.20 (1.11, 1.29)], and abdominal pain [IRR 1.11 (1.01, 1.22)] were associated with NSAID use, but not with steroids. CONCLUSION: Patients with RA and OA do not differ in the rates and risk factors for GI hospitalizations and symptoms after controlling for age, steroid use, NSAID use, or (for OA) body mass index. Prednisone is a more important risk factor among patients with RA than NSAID.

Abstract: OBJECTIVE: Using a large series of unselected consecutive patients, to investigate whether patients with fibromyalgia differ from those with rheumatoid arthritis (RA) or osteoarthritis (OA) in the number of reported comorbid conditions and in their perceived importance, and thereby to investigate differences in symptom appraisal and somatization. METHOD: In a clinical care setting, 1,298 patients with fibromyalgia and 2,396 with RA or OA participating in longitudinal data bank research as part of their routine medical care completed questionnaires concerning the presence or absence of 23 comorbid conditions, and then rated the current importance of each condition to them. Additional information concerning psychological factors and disease severity was also obtained. RESULTS: In analyses adjusted for age and sex, patients with fibromyalgia reported more conditions (4.5 vs. 3.1) than those with RA or OA. In 17 of 23 conditions, the condition was more commonly reported in fibromyalgia than in RA or OA. In 20 of the 23 conditions, the importance attached to the conditions by fibromyalgia patients exceeded that of the importance attributed by RA/OA patients. After adjustment for anxiety, statistical differences between the groups for importance was lost for 6 conditions. CONCLUSIONS: Fibromyalgia patients report more medical conditions and report that they are more important to them than do patients with RA or OA. These differences extend to conditions that might be expected to cause symptoms, as well as to those that are usually symptom free. These data suggest that, on average, patients with fibromyalgia appraise medical symptoms and their importance differently from patients with other rheumatic conditions.
