Importance of Interrelation between ABO Blood Group and Platelet Indices in Young Healthy Adults

Abstract

Objective: To highlight the importance of the interrelation between the ABO blood group system and platelet indices in healthy young adults.
 Study Design: Cross-sectional study
 Place and Duration of Study: Pathology Department, PNS Shifa Hospital, Karachi Pakistan, from Jan to Jun 2020.
 Methodology: Comprised 399 blood donors who visited the transfusion department of the hospital without any comorbidities.All the donors were requested for their informed consent before their enrolment in the study. Blood groups were determined by a simple conventional tile method. Platelet indices (Platelet count, mean platelet volume and Platelet distribution width)were studied by auto-analyzer. Blood pressures were estimated by manual auscultator technique with a mercury sphygmomanometer.
 Results: Males and females were equal in number, with a mean BMI of 19.89(1.24%). The majority of the donors, 143(35.8%),had B-Blood Group, while 140(35.1%) donors had O-Blood group, 93(23.3%) had A-Blood group, and only 23(5.8%) had AB group. Rh positivity was noted in 378(94.7%) of the donors. Different blood groups were responsible for the changes in the platelet parameters, especially MPV and PDW, as there was a significant difference in MPV and PDW values (p-value<0.05).
 Conclusion: While determining the presence of a relationship between the ABO blood group system and platelet indices, it is observed that there is a high frequency of cardiovascular diseases among B and AB blood groups in young, healthy adults.Keywords: Blood groups, Body mass index, Mean platelet volume, Platelet count, Platelet distribution width.
