[Assessment of the efficacy and safety of alemtuzumab in patients with highly active relapsing-remitting multiple sclerosis in Russian population].

OBJECTIVE:To evaluate the severity and frequency of infusion reactions (IR) in patients with highly active relapsing-remitting multiple sclerosis (MS) In Russian population receiving alemtuzumab therapy. MATERIAL AND METHODS:In retrospective study, we analyzed data from 50 patients with highly active relapsing-remitting multiple sclerosis (MS) from six Regional MS Centers in the Russian Federation who received two courses of alemtuzumab between 2018 and 2022. RESULTS:Among all IRs, the most frequently reported were hives-like rashes, which were registered in 27 people, mostly of mild severity (70.6%). Headaches were the second most common IR, observed in 17 patients (34%). When comparing the group of patients who underwent music therapy (MT) with those who received alemtuzumab therapy without MT, no statistically significant difference was found in the frequency and severity of IRs. CONCLUSION:All patients experienced IRs of varying degrees of severity. A decrease in the score on the EDSS disability scale was noted. MT did not affect the occurrence or severity of IRs.
