Mild clinical manifestations of SARS-CoV-2 related pneumonia in two patients with multiple sclerosis under treatment with ocrelizumab.

Abstract Background Recently SARS-CoV-2 has spread worldwide causing a pandemic. Little is known about disease severity in immunocompromised hosts and people receiving disease modifying therapies (DMTs). In the last decades DMTs have been widely employed, and ocrelizumab represents one of the newest therapies for the relapsing remitting and progressive forms of multiple sclerosis (MS). Objectives to describe SARS-CoV-2 related pneumonia in two MS patients under ocrelizumab treatment. Methods Case series. Results Patients showed a mild clinical course of SARS-CoV-2 related pneumonia without complications or sequelae. Conclusion Ocrelizumab treatment is not necessarily associated to increased severity in MS patients with SARS-CoV-2 infection.
