PREVALENCE OF MALARIA, THE EFFECT OF PARASITAEMIA ON BLOOD PARAMETERS AND IRON LEVEL OF INFECTED CHILDREN UNDER FIVE YEARS OF AGE IN ITU, SOUTH-SOUTH, NIGERIA

Abstract

Malaria is a devastating public health concern in Itu with varied haematological and biochemical implications. This study seeks to crystalize the prevalence of malaria, the effect of parasitaemia on some haematological parameters, and serum iron level of infected children under 5 in Itu Local Government Area, Nigeria. The study adopted a cross-sectional study involving 430 children. Blood samples were obtained from consented caregivers. Malaria prevalence and parasitaemia level were diagnosed microscopically. Haematology auto-analyzer was used to determine haematological parameters. Malaria prevalence of 41.08% was recorded in the study. The highest prevalence (42.86%) was reported among the female subjects. The difference in the infection rate between males and females was statistically significant (p<0.05). The infected children tended to have significantly lower mean haemoglobin, packed cell volume, red blood cell level, lymphocyte, monocytes, and eosinophil count, (p < 0.005) and a higher mean neutrophil, as well as white blood cell count (p < 0.05) compared to the non-infected subjects respectively. A weak correlation between the level of parasitaemia and Hb (r= 0.108), PCV(r=0.247), RBC (r= o.074), and a weak negative with WBC (r = -0.063) was also reported. The study also recorded a higher mean serum ferritin level (648 ng/ml) compared to non-infected, lower mean serum transferrin (6.41 ng/ml) compared to normal, and mean serum iron (54.40 ng/ml) was higher than normal. It is essential to pay keen attention to the evaluation of haematological and biochemical parameters in the management of malaria infection in children living in malaria-endemic areas.
