Abstract
in English, Spanish

Introduction: There is limited local information on the risk of severe COVID-19 infection in patients with multiple sclerosis (MS) who are receiving disease-modifying treatments (DMT). The aim of the study was to assess the impact of COVID-19 disease (severity and lethality) in MS patients receiving DMT.

Methods: The study was performed on a prospective cohort with EM. We included 111 patients with MS and a confirmed diagnosis of COVID-19 treated with DMT and followed up until the resolution of COVID-19.

Results: A total of six patients (5.4%; 95% CI: 2-11.4%) developed severe COVID-19 defined as requiring hospitalization in intensive care unit or death and three died (crude case fatality rate of 2.7%; 95% CI: 1.1-4.3%). The age-adjusted case fatality rate was 1.5% (95% CI: 0.6-2.4%). The factor that was independently associated with severe COVID-19 was age (OR 1.1; CI 1.0-1.3; p < 0.05) with a trend in the Expanded Disability Status Scale (EDSS) = 6 (OR 6.2; CI 0.6-56.4; p = 0.10).

Conclusion: The lethality due to COVID-19 in MS patients is low, and severity was significantly associated with age and showed a trend with EDSS = 6.

Introducción: Existe poca información local sobre el riesgo de infección grave por COVID-19 en pacientes con esclerosis múltiple (EM) que reciben tratamiento modificador de la enfermedad (DMT). El objetivo del estudio fue evaluar el impacto de la enfermedad por COVID-19 (gravedad y letalidad) en pacientes con EM que reciben DMT. Métodos: El estudio se realizó sobre una cohorte prospectiva de pacientes con EM. Se incluyeron 111 con EM y diagnóstico confirmado de COVID-19 tratados con DMT, seguidos hasta la resolución del COVID-19. Resultados: Un total de seis (5.4%; IC 95%: 2-11.4%) desarrollaron COVID-19 grave definido como requerimiento de internación en terapia intensiva o muerte, y tres fallecieron (tasa de letalidad cruda del 2.7%; IC 95%: 1.1-4.3%). La tasa de letalidad ajustada por edad fue del 1.5% (IC 95%: 0.6-2.4%). El factor que se asoció independientemente con COVID-19 grave fue la edad (OR 1.1; IC 1.0-1.3; p < 0.05) con una tendencia en la Escala del Estado de Incapacidad Ampliada (EDSS) = 6(OR 6.2; IC 0.6-56.4; p = 0.10). Conclusión: La letalidad por COVID-19 en pacientes con EM es baja y la gravedad se asoció significativamente con la edad y mostró una tendencia con EDSS = 6.
