ABSTRACT
Objective: Although diacerein was introduced in 1994 in other countries, the current literature has not established a defined role for chondroprotectives according to Cochrane. The aim of the study is to demonstrate the effects of diacerein in osteoarthritis patients based on functional assessment with analog pain scale, index Knee Society and Western Ontario and McMaster Universities Arthritis index (WOMAC index). We tested the null hypothesis of no difference between treatment with and without diacerein in terms of pain relief and improved function. Methods: 100 patients with osteoarthritis of the knee were randomly divided into two groups, with group 1 patients with only anti-inflammatory treatment and group 2 patients with inflammatory plus diacerein. They were followed for 6 months. WOMAC index, the modified Knee Society Score and visual analog scale were applied. Results: Both groups showed improvement from the initial assessment on WOMAC index but significant difference at 6 months for the 3 scores. Women showed a significant improvement in only 1 of 6 possible combination of evolution-treatment (WOMAC index), while men showed significant improvement in 5 out of 6 (all measurements except the Knee Society Score). Conclusion: Differences between patients with and without diacerein with respect to pain relief and improved function at 6 months follow up. Women showed lower response to treatment compared to men in the 3 evaluation scales.REFERENCES
