The course of COVID-19 infection in patients with multiple sclerosis-The experience of one center based on the population of Upper Silesia.

ABSTRACT

BACKGROUND: It is suspected that patients with multiple sclerosis (MS) are at greater risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection due to disability and immunotherapy. The relationship between MS and coronavirus disease 2019 (COVID-19) is uncertain. The aim of the study was to collect and analyze this relationship. METHODS: All MS patients of the Neurological Outpatient Clinic in Zabrze, Poland, were regularly questioned for the symptoms of COVID-19 and contact with an infected person. Patients that presented with COVID-19 symptoms or confirmed contact with an infected person were referred for the COVID-19 test. All patients with confirmed SARS-CoV-2 infection (n = 41) were included in the analysis. Medical records of the study group were analyzed. Patient condition was monitored in the outpatient clinic after recovery. In 26 subjects, additional examinations, including brain magnetic resonance imaging (MRI), electroneurography (ENG), electroencephalography (EEG), color duplex Doppler (CDD), visual evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs) and psychological assessment were performed following recovery. RESULTS: Only one patient required hospitalization during COVID-19 infection, whereas 87.80% of patients did not require treatment for COVID-19. In all patients, C-reactive protein (CRP) levels were below 10 mg/L. In 2.44% of patients, oxygen partial pressure was below 95%. In most MS patients, the results of further examinations after COVID-19 infection were similar to those prior to infection. Psychological assessment revealed that anxiety was found in 42.31% of patients. CONCLUSIONS: A mild course of COVID-19 in MS patients seems common despite disease-modifying drug treatment and disability. Self-isolation is recommended to reduce the number of infected patients. COVID-19 infection did not worsen the course of MS in most subjects. Patients with MS may require additional psychological support during the pandemic due to their susceptibility to anxiety.
