Effect of radiosynoviorthesis on the progression of arthropathy and haemarthrosis reduction in haemophilic patients.

description

IntroductionRepeated haemarthrosis is widely accepted as the triggering cause of synovitis and haemophilic arthropathy. A first-line treatment of chronic synovitis is radiosynoviorthesis (RS). The aim of this study was to evaluate the RS effects on the progression of arthropathy and on a reduction in bleeding in patients with haemophilia. MethodsAn observational-retrospective study was performed. Bleeding episodes in the 12months following and in the 12months preceding RS was compared. The arthropathy was clinically and radiologically analysed by age range, joint and subject, comparing those undergoing RS (Radiosynoviorthesis Group, RSG) against those not undergoing this treatment (Non-Radiosynoviorthesis Group, Non-RSG). ResultsOne hundred and seventy-four RS were performed in 71 patients (Y-90 in Knees and Re-186 in elbows/ankles/shoulder). RS resulted in significant reduction in bleeding (582 preintervention and 168 postintervention, P<.001). In general, the level of arthropathy measured clinically and radiologically was greater with age increase in both groups (RSG and Non-RSG), especially in the 25-40 age range. A significant increase (P<.05) in the progression of arthropathy was also observed, both globally by patient and specifically for each joint, in non-RSG and RSG group. ConclusionRS is an effective method to reduce the number of haemarthrosis episodes in chronic synovitis. Moreover, RS can positively affect arthropathy by slowing down its progression. However, the results obtained suggest that arthropathy may be conditioned by the subject's age, regardless of whether or not the joint has undergone RS.
