Introduction: Coronavirus Disease 2019 (COVID-19) is a novel viral disease with person-to-person transmission that has spread to many countries since the end of 2019. Although many unknowns were resolved within a year and the vaccine is available, it is still a major global health problem.
Objective: COVID-19 infection may present with a considerably wide spectrum of severity and host factors play a significant role in determining the course of the disease. One of these factors is blood groups. Based on previous experience, it is believed that the ABO blood group type affects prognosis, treatment response and length of stay in the hospital. In this study, our aim was to evaluate whether the blood group had an effect on the length of the hospital stay. To the best of our knowledge, no previous studies have assessed the effect of ABO blood groups, as well as age, on the length of the hospital stay in these settings.
Methods: In this retrospective cohort study, 969 patients admitted to our hospital between March 15, 2020 and May 15, 2020 were evaluated. The patients were divided into 4 groups according to ABO blood groups. The effect of the ABO blood group by age on the course of the disease, need for intensive care, duration of hospitalization and mortality in patients with COVID-19 infection, especially in geriatric patients, was evaluated.
Results: Of all the patients, 9.1% required admission to the intensive care unit (ICU), of whom 83% died. The average length of ICU stay was 11 days (0 - 59). The observed mortality rates in blood groups A, B, AB and 0 were 86.4%, 93.3%, 80.0% and 70.8%, respectively, indicating similar death rates in all ABO blood types. When the Rh phenotype was taken into consideration, no significant changes in results were seen.
Conclusion: As a result, we could not observe a significant relationship between blood groups and clinical outcomes in this study, which included a sample of Turkish patients with COVID-19.

Association Between ABO Blood Group, Peripheral Artery Disease Lesion Severity, and Coronary Artery Disease Coexistence.
Ann Vasc Surg

Dicle University School of Medicine, Department of Cardiology, Diyarbakır, Turkey.
Objectives: This study aims to investigate the relationship between ABO blood groups and the severity of Peripheral Artery Disease (PAD) lesions, the coexistence of Coronary Artery Disease (CAD) with PAD, and to identify which blood groups may be more predisposed to these conditions.
Methods: This study, which has a single-center and retrospective design, includes 305 patients diagnosed with Peripheral Artery Disease (PAD) between 2015 and 2021. The patients were selected from those with at least 50% stenosis detected by computed tomography (CT) angiography.
Maternal-Newborn ABO Blood Group Congruence Among Consecutive Births and Risk of Serious Neonatal Infection: Retrospective Cohort Study.
Pediatr Infect Dis J
January 2025
From the ICES, Toronto, Ontario, Canada.
Background: Differing ABO blood groups between a mother and her fetus may confer a lower risk of serious neonatal infection. How sensitization in the first pregnancy influences this phenomenon in a subsequent pregnancy is unclear. Accordingly, this study determined whether maternal-newborn ABO blood group incongruence in a first pregnancy further modifies the risk of serious infection in a subsequent pregnancy marked by ABO incongruency.

The purpose of this observational study was to investigate the association between maternal serum alkaline phosphatase (ALP) levels in late pregnancy and the risk of ABO, and to evaluate its predictive value of maternal ALP levels for ABO in women with singleton pregnancies.
Methods: A total of 11 853 consecutive pregnant women underwent hepatic and renal function tests, lipid profile assessments, ALP and high-sensitivity C-reactive protein levels measurements upon admission for labour.
Association of blood group types and clinico-pathological features of gynecological cancers (GCs).
BMC Cancer

Molecular Diseases & Diagnostics Division, Infinity Biochemistry, Infinity Solutions Unlimited, Sajjad Abad, Chattabal, Srinagar, 190010, Kashmir, India.
Background: Gynecological cancers (GCs) affect the reproductive system of females, and are of multiple types depending on the affected organ most common of which are cervical, endometrial, ovarian cancers. Among different risk factors for GCs, ABO blood group system is considered as one of the pivotal contributing factors for increased susceptibility of GCs. The aim of our study was to report on the demographics of GC patients and to investigate the relationship between the ABO blood group system and the risk of acquiring GC in our population.

Despite the advances in paleogenomics, red cell blood group systems in ancient human populations remain scarcely known. Pioneer attempts showed that Neandertal and Denisova, two archaic hominid populations inhabiting Eurasia, expressed blood groups currently found in sub-Saharans and a rare "rhesus", part of which is found in Oceanians. Herein we fully pictured the blood group genetic diversity of 22 Homo sapiens and 14 Neandertals from Eurasia living between 120,000 and 20,000 years before present (yBP).
