Abstract
In this retrospective study, we evaluated the effect of radiosynovectomy of patients with rheumatoid arthritis. Radiosynovectomy was performed in 577 joints of 137 rheumatoid patients. We applied 185 MBq yttrium-90 in knees (n = 58), 74–111 MBq rhenium-186 colloids in ankle (n = 50), wrists (n = 43) and shoulders (n = 35), and 15 to 37 MBq in finger (n = 298) and toe joints (n = 46). The effect of radiosynovectomy was scored in 4 subjective categories: excellent response (no symptoms); good response (significant reduction of symptoms); moderate response (slight decrease); and bad response (no change or worsening), of pain and/or swelling in treated joint 3 months after the procedure. Excellent or good response was observed in 57% of treated knees, 63% of shoulders, 60% of wrists, 64% of ankles, 54% of thumb bases, 55% of MCP’s, 54% of PIP’s, 53% of DIP’s, and 54% of MTP’s. Side effects associated to the RSO, i.e., swelling or transient increase of pain, were recorded in 7% of the patients that resolved within 1 month. No patient had any non-reversible skin alteration after treatment, only slight erythema was observed in 5 patients. Radiosynovectomy is effective and safe in the treatment of rheumatoid arthritis.
