Investigating outcomes and treatment of long coronavirus disease 2019 in patients with multiple sclerosis treated with rituximab: A case series study
Abstract
Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system, characterized by the destruction of the myelin sheath of nerves. MS patients treated with rituximab, an immunosuppressive drug, experience reduced immunoglobulin levels, which increases their risk of various infections, including coronavirus disease 2019 (COVID-19). During the COVID-19 pandemic, many of these patients developed long-term symptoms following infection. These chronic symptoms have led to significant complications and, in some cases, increased mortality. In this case series study, we investigated long COVID-19 symptoms in MS patients treated with rituximab and the effects of intravenous immunoglobulin (IVIG) therapy in alleviating chronic symptoms. The results demonstrated that the patients' long-term symptoms responded to IVIG treatment, with significant improvements in respiratory symptoms, fever, immune parameters, and a reduction in C-reactive protein levels. This study highlights the importance of targeted management of long COVID-19 in immunocompromised populations and suggests that COVID-19 patients with immune deficiencies require specific therapeutic approaches.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 19 participants or records.
