PCR analysis was carried out on samples collected from all patients for detection of malaria parasites; the primers specific for the polymorphic regions block 2 of merozoite surface protein 1 MSP1 and block 3 of MSP2 were designed and described previously.

Whether HMS is responsible for this high mortality is a fact that still needs to be established [ 6 ]. Acta Med Acad Sci Hung. J Trop Med Hyg.

Bull Soc Pathol Exot. Hyperreactive Malarial Splenomegaly HMS is defined as a massive enlargement of the spleen resulting from abnormal immune responses after repeated exposure to the malaria parasites. On the one hand, recent reports showed that more sensitive diagnostic tools have found a higher proportion of malarial infection in HMS patients [ 17 ].
