Background/objectives: Alopecia areata (AA) is an autoimmune disease characterized by noncicatricial hair loss localized on hair, beard, mustache, eyebrow, eyelash, and sometimes on the body. Although etiopathogenesis is not fully understood, many studies show remarkable associations between various diseases and ABO blood groups. However, there is no study with AA and blood groups.
Methods: Healthy people and patients with AA were included in this study. A total of 155 patients with AA and 299 healthy controls were included in the study.
Results: ABO blood group distribution in patients with AA and distribution of healthy donors were similar. However, Rhesus factor positivity in the AA group was significantly higher than in healthy donors. The relationship between stress and AA was high as known. But, ABO blood group and Rhesus factor were not in a significant connection with stress.
Conclusion: We conclude that there was no association between ABO blood group and AA, but the observed distribution of Rhesus blood group differed slightly but significantly from that of the healthy population. The result of the study shows a small but statistically significant difference in the Rh blood group between patients with AA and the healthy population blood groups. This result is important because it suggests that genetic factors may influence the development of AA. The role of blood groups in the development of AA remains to be determined. We believe that the studies which will be carried out in other centers with wider series will be more valuable to support this hypothesis.

Background And Objectives: The AB is a rare phenotype in the ABO blood group system. Here, we first report a novel ABO mutation discovered in a Chinese woman with an AB. Third-generation sequencing was employed to investigate the molecular mechanisms underlying AB.

Sickle cell disease and β-thalassemia are important health problems in Middle Eastern countries. Transfusion is the cornerstone of the management in these disorders, and red blood cell alloimmunization is among the well-recognized adverse effects associated with it. We reviewed the literature on published studies on alloimmunization prevalence, its associated risk factors, and transfusion policies employed in these countries.

Along with numerous human migrations, gene trait transfer also occurs. This study aimed to investigate the effects of migration on blood group changes in Turkey by determining the blood group distribution of Turkish citizens living in Turkey, the blood group distribution of foreign nationals coming to Turkey, and the blood group distribution of 0-year-old babies born in the last four years.

Background: Although existing studies have reported associations between blood group A and cardiometabolic diseases (CMD), most have focused on dominant inheritance models. However, genome-wide association studies have mostly been based on additive genotypes. This study aims to investigate the association between the blood group A allele and 15 CMD using recessive, dominant, and additive models and identify potential mediators.

Background And Objectives: Blood safety is the top priority in transfusion medicine. However, patients in Vietnam are only transfused with ABO and RhD compatible blood products, which could pose a threat to induce alloimmunization. This study was performed to provide information about the frequencies of antigens and phenotypes of clinically significant blood groups in Vietnamese donors.
