Predictors of C - reactive protein Response in Children Infected with <i>Plasmodium falciparum</i> Malaria

Abstract

Objective: To assess the predictors of C-reactive protein response in plasmodium falciparum malaria as seen in children in a malaria endemic region of Nigeria.
Design: A prospective cross-sectional study.
Setting : The Children Out-patient (CHOP) Clinic, Children Emergency Unit (CHEU), Child Welfare/Growth Monitoring Clinic, Immunisation Centre and Paediatric Ward of the University of Uyo Teaching Hospital (UUTH), Uyo in Akwa-Ibom State.
Subjects : Three hundred and sixty children aged six to sixty months with microscopically confirmed P. falciparum malaria compared with 360 healthy children without malaria parasitaemia matched for age and gender.
Results: The predictors of the C-reactive protein response in malaria (CRP ≥ 10mg/l) were fever (t = 6.867; p = 0.001), malaria parasite count (t = 5.387; p = 0.001), severe anaemia (t = -11.23; p = 0.001) and age. Younger children had a greater CRP response. The logistic regression curve showed a 66.9% sensitivity, 92.1% specificity, positive predictive value, 83.2% and negative predictive value of 82.2% of predicting C-reactive protein response in malaria.
Conclusion: P. falciparum malaria induces significant CRP responses. Younger children who present with fever, hyperparasitaemia and severe anaemia are more likely to have C-reactive protein response with malaria.
