Frequency of ABO and RhD Blood Groups in Patients with Celiac Disease

Celiac disease (CD) is a popular autoimmune disorder induced by gluten-containing foods and other environmental, and genetic factors. Every individual's red blood cell expresses over two million ABO blood-type antigens. Furthermore, the stomach and small intestine are major expression sites for the ABH antigens. This study was intended to assess the distribution of ABO and Rh blood types in Libyan patients with celiac disease as well as compare between CD and healthy control groups regarding complete blood count parameters. Samples from 250 CD patients and 45 healthy control groups represented by 80 males (27.1%) and 215 females (72.9%) were enrolled in the study. The samples of CD were collected from patients who attended the gastroenterology outpatient clinic at Tripoli University Hospital (TUH) for follow-up. Two hundred and fifty blood samples were serologically screened for ABO, and Rh antigens using a tube agglutination test. Another group of healthy subjects (n = 45) and CD patients (n = 45) were analyzed for CBC test. The findings showed that the most observed ABO blood group among celiac patients was blood group O 129 (51.6%), followed by blood group A 80 (32%), and Rh-positive 222 (88.8%). Furthermore, the heritable proportion was 33%, with 21% classified as first-degree and 12% as second-degree hereditary. Additionally, the result of the independent Sample (T) test to compare RBCs, HGB, HCT, and NUT levels in blood between CD patients and healthy control showed that there were significant differences in the RBCs, HGB, and HCT counts with p-value = 0.034, <0.001, and <0.001 respectively. In contrast, Mann-Whitney U test results revealed significant differences in the PLT, MCV, MCH, and MCHC counts with p-value = <0.001, and for LYM with p-value = 0.003. Future studies on these simple inflammatory markers can guide us in predicting the diagnosis and prognosis.
