INTRODUCTION/AIMS: Coronavirus disease-2019 (COVID-19) may have a more severe course in patients with myasthenia gravis (MG). We aimed to assess severity of the infection and factors contributing to its severity in a group of MG patients, most of whom were not hospitalized.
METHODS: One hundred forty outpatients with MG followed between March 2020 and April 2021 were included in our study. Patients were asked to respond to a brief questionnaire in person, by telemedicine, or through electronic messages.
RESULTS: Nineteen patients tested positive for COVID-19 by polymerase chain reaction. Two were asymptomatic. Of the 17 symptomatic patients, 11 had mild symptoms. They either had no treatment or received antivirals, antibiotics, and anticoagulants. Their myasthenia was well-controlled before infection and was unaffected by COVID-19. Three patients with moderate COVID-19 required hospitalization, but not intensive care, and had full recovery. Three other patients, the oldest in the cohort, had severe disease: One patient with a postsurgery myasthenic exacerbation before the infection needed intensive care without intubation, but recovered completely; two morbidly obese patients with comorbidities required intubation and died. Corticosteroids were increased in four of the six moderate/severely affected patients. Immunosuppressive (IS) agents were generally continued. Hydroxychloroquine (HCQ) for COVID-19 was used in one patient.
DISCUSSION: Most patients had mild COVID-19 and all but two patients recovered. The design of the study made it possible to capture mild cases. Having well-controlled MG before infection and absence of comorbidities likely affected the course of the infection favorably. IS did not influence the progression.
