Pulse immunosuppressive therapy for multiple sclerosis during the SARS-CoV-2 lockdown de-escalation plan: Safety algorithm.

Introduction: The COVID-19 pandemic is changing approaches to diagnosis, treatment, and care provision in multiple sclerosis (MS). During both the initial and peak phases of the epidemic, the administration of disease-modifying drugs, typically immunosuppressants administered in pulses, was suspended due to the uncertainty about their impact on SARS-CoV-2 infection, mainly in contagious asymptomatic/presymptomatic patients. The purpose of this study is to present a safety algorithm enabling patients to resume pulse immunosuppressive therapy (PIT) during the easing of lockdown measures.
