Markers of Inflammation in Children With Severe Malarial Anaemia
OBJECTIVE. To investigate if severe malarial anaemia is associated with a specific immune response pattern, we determined serum levels of neopterin (a marker of activation of macrophages by interferon-γ) and of the anti- inflammatory cytokines, interleukins 4 and 10. METHODS. Zambian children < 6 years of age presenting to a rural hospital with cerebral malaria were studied. Twenty-one children with admission haemoglobin concentrations ≤ 5 g/dl were classified as having severe anaemia and 40 with haemoglobin concentrations ≥ 7 g/dl served as a control group. RESULTS. Logistic regression modelling indicated that a 10-fold rise in serum neopterin concentrations was associated with a 50-fold increase in the estimated odds of having severe anaemia (P = 0.015), while a 10-fold rise in serum interleukin 4 concentrations was associated with a 10-fold decrease in the estimated odds of having severe anaemia (P = 0.023). Increasing serum interleukin 10 concentrations, measured in less than half of the subjects, were associated with a nonsignificant reduction in the odds of having severe anaemia (P = 0.095). CONCLUSION. Development of severe malarial anaemia may be directly associated with serum neopterin concentrations and inversely correlated with serum interleukin 4 levels.
