RESUMEN
AIM: To study the quality of life (QoL) in patients with multiple sclerosis (MS) treated with ocrelizumab for at least 12 months. MATERIAL AND METHODS: Thirty-eight patients were observed, including 13 with primary progressive MS (PPMS), 15 with highly active relapsing-remitting MS (HAMS) and 10 with secondary progressive MS (SPMS) with relapses. QoL was studied using unspecific SF-36 and MS-specific MusiQoL questionnaires. Depression and fatigue were assessed with the Beck Depression Scale (BDS) and the Modified Fatigue Impact Scale (MFIS). RESULTS AND CONCLUSION: Basic characteristics of QoL indexes of the patients were similar to those previously reported for these MS variants. After 6 and 12 months, a significant increase in the indexes of the majority of SF-36 and MusiQoL scales was identified that shows a significant improvement in both physical and psychological domains of QoL. The significant and rapid decrease in depression severity after 6-month treatment with ocrelizumab may at least in part be associated with improvement of indexes of vitality, general health, social relations and the total QoL score.
