Clinical Features and Treatment of Patients Infected With SARS-CoV-2 Omicron Variant While Hospitalized Due to Stroke: A Single Center Study in Japan.

Publication date: Feb 01, 2024

In December 2019, COVID-19 spread rapidly across the globe. Throughout the pandemic, SARS-CoV-2 repeatedly mutated, transitioning from the alpha variant to the omicron variant. The severity and mortality of COVID-19 have been linked to age, sex, and the presence of underlying diseases (respiratory, cerebrovascular, cardiovascular, metabolic, and immune diseases, as well as cancer). The clinical features of patients infected with COVID-19 following a stroke, however, are fully unknown. Therefore, it is significant to explore the appropriate treatment for these patients based on their clinical features. Of the 6175 patients who visited Asahi Hospital (Tokyo, Japan) between November 2022 and February 2023, 206 were admitted. Of these 206 patients, the 44 that contracted COVID-19 while hospitalized for strokes were retrospectively analyzed. Six (13. 6%) of these patients died; four expired due to coagulopathy associated with ischemic heart failure and recurrent ischemic cerebrovascular disease. The mean D-dimer level increased to 3. 53 in the deceased patients, while it was 1. 64 in all patients. The platelet count was low in three of the deceased patients, while it was high in two patients. The severity of COVID-19 was significantly correlated with a high modified Rankin Scale (mRS) score and a high National Institute of Health Stroke Scale (NIHSS) score. The timing of vaccination is inversely correlated with COVID-19 severity. Patients with COVID-19 after a stroke have high mortality rates due to coagulopathy. Stroke patients with high mRS scores and high NIHSS scores are more likely to develop severe COVID-19. Anticoagulant therapy should be administered to COVID-19 patients with high mRS scores following a stroke.
