Abstract

Background

The new coronavirus SARS-CoV-2 infection has spread worlwide becoming a pandemic never before seen. Multiple Sclerosis (MS) patients in a state of immunosuppression (IS) may be exposed to a greater risk of COVID-19 complications, although there is increasing evidence postulating a possible protective role of selective IS.

Objectives

To describe the real-world experience in MS patients with SARS-CoV-2 infection at a MS Unit of a hospital in Madrid, Spain. We describe clinical evolution and MS treatment actions

Methods

Observational, prospective and usual clinical practice study in MS patients affected by SARS-CoV-2 infection with clinical diagnosis (at least three of the following: fever, anosmia, cough, diarrhea, myalgia) and/or microbiological diagnosis (PCR in nasopharyngeal swabs and/or serology).

Results

41 SARS-CoV-2 infection cases were registered. 21 were women with a mean age of 39,4 years old (DS10,3). 38 were relapsing-remitting MS patients and 3 had a progressive MS. The mean MS time course was nine years (DS1,4). 39 patients were treated with disease-modifying therapies (DMTs): 46,3% with oral agents, 39% with monoclonal antibodies and 10% with injectable agents. 27 patients were previously treated with other DMTs. The median Expanded Disability Status Scale (EDSS) was 2,5 (DS0,7). 11 patients had clinical activity the previous year. 18 cases were confirmed by PCR and/or serology and 23 were clinically diagnosed. 17% of the patients were admitted to hospital (6 were diagnosed with pneumonia) and none required admission to the intensive care unit. There were no deaths.Three patients had other comorbidities. Admitted patients were older and had higher EDSS score without statistical significance. MS got worse in 7 patients. DMTs were stopped or delayed in 10 patients due to the SARS-CoV-2 infection.

Conclusions

All the MS patients studied had a good outcome of the SARS-CoV-2 infection. Only 17% of them required admission to hospital and 14,6% of the cases were asymptomatic. 95% of the patients were treated with DMTs. From our experience, the SARS-CoV-2 infection does not seem to entail a more aggressive form of the disease in this group of patients. Selective IS may favor the good evolution. Larger clinical registers are needed to establish solid conclusions.
