ABO and RH blood group distribution shows significant variations among different geographical locations and ethnic groups. It is important to study the relative frequency of blood groups because of its role in genetics, blood transfusion, organ transplantation, forensic medicine, and its association with diseases. This study was conducted to determine the ABO and Rh blood group distribution in Aleppo Province in the north of Syria.
The study was conducted in Aleppo University Hospital, the Central Health Center in Aleppo Province, during the period from April 15, 2019, to July 30 of the same year. We included 1576 patients whose blood was typed as a presurgery preparation, or for any indication of blood transfusion. Blood groupings were performed by standard slide method, using the anti-A, anti-B, and anti-D monoclonal antisera. The most common ABO blood group was “A” followed by “O,” “B,” and “AB.” RH positive was more common than RH negative.
Nearly 38.1%, 35.6%, 17.4%, and 8.9% of the patients were from blood groups A, O, B, and AB, respectively. RH +ve and RH −ve participants accounted for 87.1% and 12.9%, respectively. In more detail, 34.6% of the sample were A+, 3.5% were A−, 29.8% were O+, 5.8% were O−, 15.5% were B+, 1.9% were B−, 7.1% were AB+, and 1.8% were AB−.
Literature regarding phenotypic and genotypic blood grouping in Syria is scarce and controversial. Most studies are conducted in Damascus, the capital of Syria., Only two conflicting, small-scale studies investigated the blood group distribution in Aleppo., Our study supported the findings of the study by Aljarad et al., which included healthy people presenting to Aleppo University Hospital.
The present study was conducted at a single center including 1576 patients. Larger-scale, population-based, multicentric, genetic studies are recommended to study the prevalence of blood group in Aleppo, and in Syria as a whole.
