Abstract: BACKGROUND: Spontaneous reporting systems for adverse drug reactions (ADRs) are handicapped by under-reporting and limited detail on individual cases. We report an investigation from a local surveillance for serious adverse drug reactions associated with disease modifying anti-rheumatic drugs that was triggered by the occurrence of liver failure in two of our patients. METHODS: Serious ADR reports have been solicited from local clinicians by regular postcards over the past seven years. Patients', who had hepatotoxicity on sulfasalazine and met a definition of a serious ADR, were identified. Two clinicians reviewed structured case reports and assessed causality by consensus and by using a causality assessment instrument. The likely frequency of hepatotoxicity with sulfasalazine was estimated by making a series of conservative assumptions. RESULTS: Ten cases were identified: eight occurred during surveillance. Eight patients were hospitalised, two in hepatic failure - one died after a liver transplant. All but one event occurred within 6 weeks of treatment. Seven patients had a skin rash, three eosinophilia and one interstitial nephritis. Five patients were of Black British of African or Caribbean descent. Liver enzymes showed a hepatocellular pattern in four cases and a mixed pattern in six. Drug-related hepatotoxicity was judged probable or highly probable in 8 patients. The likely frequency of serious hepatotoxicity with sulfasalazine was estimated at 0.4% of treated patients. CONCLUSION: Serious hepatotoxicity associated with sulfasalazine appears to be under-appreciated and intensive monitoring and vigilance in the first 6 weeks of treatment is especially important.

Abstract: BACKGROUND: Hydrotherapy is highly valued by people with rheumatoid arthritis yet few studies have compared the benefits of exercises in heated water against exercises on land. In particular, data on quality of life is rarely reported. This is especially important because patients treated with hydrotherapy often report an enhanced sense of well-being. We report a randomised controlled trial in which we compared the effects of hydrotherapy with exercises on land on overall response to treatment, physical function and quality of life in patients with rheumatoid arthritis. METHODS: One hundred and fifteen patients with RA were randomised to receive a weekly 30-minute session of hydrotherapy or similar exercises on land for 6 weeks. Our primary outcome was a self-rated global impression of change--a measure of treatment effect on a 7-point scale ranging from 1(very much worse) to 7 (very much better) assessed immediately on completion of treatment. Secondary outcomes including EuroQol health related quality of life, EuroQol health status valuation, HAQ, 10 metre walk time and pain scores were collected at baseline, after treatment and 3 months later. Binary outcomes were analysed by Fisher's exact test and continuous variables by Wilcoxon or Mann-Whitney tests. RESULTS: Baseline characteristics of the two groups were comparable. Significantly more patients treated with hydrotherapy (40/46, 87%) were much better or very much better than the patients treated with land exercise (19/40, 47.5%), p < 0.001 Fisher's exact test. Eleven patients allocated land exercise failed to complete treatment compared with 4 patients allocated hydrotherapy (p = 0.09). Sensitivity analyses confirmed an advantage for hydrotherapy if we assumed non-completers would all not have responded (response rates 70% versus 38%; p < 0.001) or if we assumed that non-completers would have had the same response as completers (response rates 82% versus 55% p = 0.002). Ten metre walk time improved after treatment in both cases (median pre-treatment time for both groups combined 10.9 seconds, post-treatment 9.1 s, and 3 months later 9.6 s). There was however no difference between treatment groups. Similarly there were no significant differences between groups in terms of changes to HAQ, EQ-5D utility score, EQ VAS and pain VAS. CONCLUSION: Patients with RA treated with hydrotherapy are more likely to report feeling much better or very much better than those treated with land exercises immediately on completion of the treatment programme. This perceived benefit was not reflected by differences between groups in 10-metre walk times, functional scores, quality of life measures and pain scores.

Article Monitoring and assessing the safety of disease-modifying antirheumatic drugs: a West Midlands experience. 2002

Abstract: BACKGROUND: Serious adverse events may occur from the use of disease modifying antirheumatic drugs (DMARDs) used to treat rheumatoid arthritis. We describe preliminary data from a regional surveillance scheme. Our aims were to identify a broad range of potential adverse events, to identify deficiencies in care and examine the management of common events in order to improve care. METHODS: Adverse events were sought by regular postcards to clinicians in the West Midlands region of the UK. Each reported case was carefully described and the opinions of at least three peer-reviewers were sought on cause-effect relationships, the potential for prevention and the appropriateness of management. RESULTS: Forty-four serious adverse events associated with DMARD use were reported between December 1999 and October 2001. Events included eight patients with malignancies, two with pancytopenia taking methotrexate, three with septic arthritis, and two with septicaemias. Fifteen cases have been peer-reviewed in detail, so far. At least two reviewers thought that eight events were related to DMARD use and that two were preventable. Agreement between pairs of reviewers was fair or moderate (weighted kappa 0.23-0.5). DISCUSSION: We have successfully implemented a regional system for identifying potential drug-related serious adverse events. A diverse range of potential drug-related events has been seen. Early analyses have highlighted the difficulties of determining cause-effect relationships between a drug and an event.
