Abstract

There is evidence that Plasmodium falciparum (Pf) malaria is influenced by ABO blood type but the extent of association is not fully established. Some investigators opinioned that haemoglobin electrophoretic patterns are a factor in susceptibility to Pf infection but there is no consensus on possible association between it and ABO blood group and Hb genotypes. This study was designed to determine the prevalence of Pf among different ABO blood groups and Hb electrophoretic patterns of medical students of a tertiary institution in Nnewi, Nigeria. A total of 80 subjects (41 males and 39 females) aged 18-30 years who reported to the Medical Centre of the institution on account of febrile illness were recruited for the study. Information on age, previous malaria episodes and recent use of prophylaxis were sought. Three milliliters (3ml) of blood were collected into EDTA container for ABO grouping, Hb electrophoresis and blood films for P. falciparum detection and quantification by microscopy. Pf prevalence among the subjects was 47.5% (38/80). Thirty-one (38.75%) of the subjects were of blood group O, 27 (33.75%) group A, 19 (23.75%) blood group B and 3(3.75%) blood group AB. Fifty-two (65%) of the subjects were Hb AA and 28 (35%) AS. No significance difference was seen between malaria episodes and ABO blood groups; Hb electrophoretic patterns; gender and parasite density (p>0.05) respectively. A negative correlation was observed between parasite density and age (r= -0.180, p = 0.109). Pf infection, frequency of infection and parasite load is not influenced by blood group and Hb electrophoretic patterns in our study population.
