RESUMO
BACKGROUND: There is little information regarding the safety of intravenous tissue plasminogen activator (IV-tPA) in patients with stroke and COVID-19. METHODS: This multicenter study included consecutive stroke patients with and without COVID-19 treated with IV-tPA between February 18, 2019, to December 31, 2020, at 9 centers participating in the CASCADE initiative. Clinical outcomes included modified Rankin Scale (mRS) at hospital discharge, in-hospital mortality, the rate of hemorrhagic transformation. Using Bayesian multiple regression and after adjusting for variables with significant value in univariable analysis, we reported the posterior adjusted odds ratio (OR, with 95% Credible Intervals [CrI]) of the main outcomes. RESULTS: A total of 545 stroke patients, including 101 patients with COVID-19 were evaluated. Patients with COVID-19 had a more severe stroke at admission. In the study cohort, 85 (15.9%) patients had a hemorrhagic transformation, and 72 (13.1%) died in the hospital. After adjustment for confounding variables, discharge mRS score ≥2 (OR: 0.73, 95% CrI: 0.16, 3.05), in-hospital mortality (OR: 2.06, 95% CrI: 0.76, 5.53), and hemorrhagic transformation (OR: 1.514, 95% CrI: 0.66, 3.31) were similar in COVID-19 and non COVID-19 patients. High-sensitivity C reactive protein level was a predictor of hemorrhagic transformation in all cases (OR:1.01, 95%CI: 1.0026, 1.018), including those with COVID-19 (OR:1.024, 95%CI:1.002, 1.054). CONCLUSION: IV-tPA treatment in patients with acute ischemic stroke and COVID-19 was not associated with an increased risk of disability, mortality, and hemorrhagic transformation compared to those without COVID-19. IV-tPA should continue to be considered as the standard of care in patients with hyper acute stroke and COVID-19.

Coronary artery disease (CAD) and ischemic stroke (IS) are commonly considered distinct disease phenotypes. However, there is some evidence in favor of a degree of overlap between genetic susceptibility to CAD and genetic risk factors for IS. In the present study, we aimed to examine the role of two single-nucleotide polymorphisms (SNPs), rs3825807 and rs11556924, located in the ADAMTS7 and ZC3HC1 genes, respectively, associated with CAD in published GWASs in European populations and their possible contribution to the development of coronary atherosclerosis and cerebral LA atherosclerosis in a case-control study of an the Iranian population. The sample size was 400, and the methodology for SNP genotyping was ARMS-PCR. Both SNPs showed strong associations with CAD in the analyses comparing significant CAD and myocardial infarction (MI) with controls. None of them, however, were associated with MI in patients with significant CAD. Our findings further support the role of the ADAMTS7 locus in promoting atherosclerosis in LAs of the brain. Regarding ZC3HC1 rs11556924, our study further supports the observed association of rs11556924 with LA IS coming from previous GWASs. In conclusion, the data showed that common variants in ADAMTS7 and ZC3HC1 genes contribute to an increased risk for both CAD and LA (atherosclerotic) IS.
