Distribution of cytokines (IFN-γ, IL-10 and IL-6) concentrations according to the parasitemia. Plasma concentrations of pro- and anti-inflammatory cytokines were quantified in P. falciparum-infected children. P. falciparum-infected children were subdivided into three groups based upon the parasite density. Low density group was characterized by parasite density ≤ 1000 parasites/µl of blood. Medium and high density groups were defined by parasite density included between 1000 and 10000 parasites/µl and > 10000 parasites/µl of blood, respectively. Significant differences between the groups were done by Mann-Whitney test. *P < 0.05 compared to low density group (≤ 1000 parasites/µl).
