Relationship between the hematological indices and COVID-19

Abstract

Background: Recently, the novel coronavirus disease-2019 (COVID-19) has a wide spread around the world. Clinically, it was responsible for respiratory illness ranged from mild to life-threatening infection. The study aimed to investigate the link of gender, age, ABO blood groups, and hematological indices with COVID-19 infection. Methods: One hindered COVID-19 cases, as confirmed using reverse transcription–polymerase chain reaction test, were checked for some sociodemographic features, blood group, and hematology parameters. A blood sample was collected from each person in an EDTA container and immediately tested for blood group using commercial antisera, in addition to complete blood count parameters using of a semiautomated hematology analyzer (Mindray BC-3200). Results: Of 100 COVID-19 patients, 52% were male and 48% were female. About 33% and 31% of the study participants were of age group 15–31 and 32–49 years, respectively. The majority (37%) of COVID-19 patients carried blood group O+ve, followed by A+ve (24%). A+ve blood group was significantly more reported in males (32.7%) than females (14.6%). Notably, 61% of participants showed low Hb level. Erythropenia was detected in 41% of the participants, while thrombocytopenia was observed only in 19% of the patients. Moreover, lymphocytopenia was detected in 82%, low packed cell volume in 66%, decreased mean corpuscular volume in 20%, and declined mean corpuscular hemoglobin concentration in 8% of the participants. In contrast, leukocytosis and neutrophilia were found in 69% and 73% of the participants, respectively. Conclusion: Taken together, the study findings highlighted the link of COVID-19 with age, gender, blood groups, and hematology parameters, which is important in diagnosis, prognosis, and management of illness.
