“…Whether these associations result in clinically worse outcomes with different blood groups has been debated. Multiple observational studies reported increased risk and worse outcome in blood group A as compared to blood group O; however, many other observational studies did not find any significant differences [ 9 - 15 ].…”

Background Blood group type A has been associated with increased susceptibility for coronavirus disease 2019 (COVID-19) infection when compared to group O. The aim of our study was to examine outcomes in hospitalized COVID-19 patients among blood groups A and O. Methods This is an observational study. Kruskal-Wallis and Chi-square tests were used to compare continuous and categorical variables. Multivariable logistic regression models were used to examine association of blood groups with rates of mortality and severity of disease. All adult patients (> 18 years) admitted with COVID-19 infection between March 1, 2020 and March 10, 2021 at a large community hospital in Northeast Georgia were included. We compared mortality, severity of disease (use of mechanical ventilation, vasopressor, and acute renal failure), rates of venous thromboembolism and inflammatory markers between the blood groups. We used multivariable logistic regression model to adjust for demographical and clinical characteristics, use of COVID-19 medications and severity. Results A total of 3,563 of 5,204 admitted patients had information on blood groups. Of these, 1,301 (36.5%) were group A, 377 (10.6 %) were group B, 133 (3.7%) were group AB and 1,752 (49.2%) were group O. On adjusted analysis, there were no significant differences in rates of intensive care unit (ICU) admissions, mechanical ventilation, vasopressors, acute renal failure, venous thromboembolism and readmission rate between the blood groups A and O. In-hospital mortality was also not statistically different among the blood groups A and O (17.5% vs. 20.1%; P = 0.07). On adjusted analysis, in-hospital mortality was not lower in blood groups O (odds ratio (OR): 1.06; 95% confidence interval (CI): 0.80 - 1.40, P = 0.70). Conclusions Once hospitalized with COVID-19 infection, blood groups A and O are not associated with increased severity or in-hospital mortality.

Background This study provides the first systematic review and meta-analysis to identify the predictors of unfavorable prognosis of COVID-19 in children and adolescents. Methods We searched literature databases until July 2021 for studies that investigated risk factors for unfavorable prognosis of children and adolescents with COVID-19. We used random-effects models to estimate the effect size with 95% confidence interval ( CI ). Findings We identified 56 studies comprising 79,104 individuals. Mortality was higher in patients with multisystem inflammatory syndrome (MIS-C) (odds ratio [ OR ]=58.00, 95% CI 6.39–526.79) and who were admitted to intensive care ( OR =12.64, 95% CI 3.42–46.68). Acute respiratry distress syndrme (ARDS) ( OR =29.54, 95% CI 12.69–68.78) and acute kidney injury (AKI) ( OR =55.02, 95% CI 6.26–483.35) increased the odds to be admitted to intensive care; shortness of breath ( OR =16.96, 95% CI 7.66–37.51) increased the need of respiratory support; and neurological diseases ( OR =5.16, 95% CI 2.30–11.60), C-reactive protein (CRP) level ≥80 mg/L ( OR =11.70, 95% CI 4.37–31.37) and D-dimer level ≥0.5ug/mL ( OR =20.40, 95% CI 1.76–236.44) increased the odds of progression to severe or critical disease. Interpretation Congenital heart disease, chronic pulmonary disease, neurological diseases, obesity, MIS-C, shortness of breath, ARDS, AKI, gastrointestinal symptoms, elevated CRP and D-dimer are associated with unfavourable prognosis in children and adolescents with COVID-19.
