NEW OPPORTUNITIES THERAPY IN PATIENTS WITH KNEE JOINT OSTEOARTHRITIS AND METABOLIC SYNDROME

Abstract

Objective/introduction. Evaluation of efficacy and safety of diacerein therapy in patients with knee joint osteoarthritis (OA) and metabolic syndrome (MS). Materials and methods. 55 outpatients (50 women and 5 men) with MS and stage 2-3 OA of knee joint according to Kellgren-Lawrence, with intensity of pain syndrome > 40 mm according to visual analogue scale (VAS) from 4 Russian Federation subjects were enrolled in the study. Average age of patients was 59.7 ± 7.3 years , mean BMI is 33 ± 5,49 kg/m2, the duration of the disease is 8 (5-10 years). Duration of the study was 9 months (6 months of therapy: 1 capsule (50 mg) per day for the first month, 2 capsules (100 mg) per day for the next 5 months, and follow-up for 3 months). Evaluation of the efficacy and safety of the treatment was conducted according to generally accepted criteria. All patients were underwent biochemical tests at the beginning and at the end of therapy. Results. The study resulted in a statistically significant reduction in pain when walking according to VAS as early as in 1 month from the beginning of treatment; the further significant improvement was observed during the entire 6-month therapy. Withdrawal of therapy (the observation period was 3 months) didn’t increase the pain syndrome. Evaluation according to Womac index also revealed identical regularity. A statistically significant improvement in the quality of life according to EQ-5D was also identified during the whole period of observation. By the end of the therapy, 92.5% of the patients were OMERACT - OARSI - responders and 64.2% of patients had completely withdrawn from NSAID. Against the background of the therapy, there was a significant decrease in BMI, LDL, TG, glucose, uric acid levels. Conclusion: The data obtained make it possible to recommend diacerein as a basic therapy for OA in patients with MS. On the background of therapy, the patients showed statistically significantly reduction in pain, stiffness, the need for NSAIDs, improved the quality of life and the function of the joints. In addition, the body weight decreases reliably, the lipidogram, carbohydrate and protein metabolism parameters also improved.
