Author Correction: Neurological immunotherapy in the era of COVID-19 - looking for consensus in the literature

Abstract

n the originally published version of this article, the description of the study by Sormani et al. (ref. 14) in the third paragraph of the section entitled ‘B cell-depleting therapies’ was incorrect. The description should read: In 232 patients with multiple sclerosis and suspected or proven COVID-19, the severity of COVID-19 was classified as mild (no or mild pneumonia) in 222 (96%), severe (shortness of breath, respiratory rate ≥30 breaths/min, blood oxygen saturation ≤93%, PaO2:FiO2 < 300 mmHg/%, and an increase in lung infiltrates of >50% within 24–48 h) in 4 (2%) and critical (respiratory failure, septic shock and multiple organ dysfunction or failure) in 6 (3%). Of the 6 patients with critical illness, 1 recovered and 5 died. Of 28 patients receiving a B cell-depleting therapy, 3 (10%) developed a severe or critical disease course.
