SARS-CoV-2 infection might be a predictor of mortality in intracerebral hemorrhage

Background: SARS-CoV-2 infection may be associated with uncommon complications such as intracerebral hemorrhage (ICH), with a high mortality rate. We compared a series of hospitalized ICH cases infected with SARS-CoV-2 with a non-SARS-CoV-2 infected control group and evaluated if the SARS-CoV-2 infection is a predictor of mortality in ICH patients.Methods: In a multinational retrospective study, 63 cases of ICH in SARS-CoV-2 infected patients admitted to 13 tertiary centers from the beginning of the pandemic were collected. We compared the clinical and radiological characteristics and in-hospital mortality of these patients with a control group of non-SARS-CoV-2 infected ICH patients of a previous cohort from the country where the majority of cases were recruited.Results: Among 63 ICH patients with SARS-CoV-2 infection, 23 (36.5%) were women. Compared to the non-SARS-CoV-2 infected control group, in SARS-CoV-2 infected patients, ICH occurred at a younger age (61.4 +/- 18.1 years versus 66.8 +/- 16.2 years, P = 0.044). These patients had higher median ICH scores ([3 (IQR 2-4)] versus [2 (IQR 1-3)], P = 0.025), a more frequent history of diabetes (34% versus 16%, P = 0.007), and lower platelet counts (177.8 +/- 77.8 x 109/L versus 240.5 +/- 79.3 x 109/L, P < 0.001). The in-hospital mortality was not significantly different between cases and controls (65% versus 62%, P = 0.658) in univariate analysis; however, SARS-CoV-2 infection was significantly associated with in-hospital mortality (aOR = 4.3, 95% CI: 1.28-14.52) in multivariable analysis adjusting for potential confounders.Conclusion: Infection with SARS-CoV-2 may be associated with increased odds of in-hospital mortality in ICH patients.
