Cerebral malaria in rural India.

OBJECTIVE: A cross-sectional hospital based study was carried out to investigate clinical features and outcome of cerebral malaria in a rural area.
METHODS: All children fulfilling inclusion criteria, were enrolled and were entered on specially designed proforma. Their peripheral smear (PS) were studied based on which the diagnosis was classified as definite cerebral malaria (DCM) and probable cerebral malaria (PCM). RESULT: There were 2991 admissions in pediatric ward, of which 1394 (46.6%) were for fever. Of 781 (56.6%) cases with fever no cause was identified. Of the 56 cases positive for malarial parasite on PS 4.3% were Plasmodium vivax (PV) and 2.8% Plasmodium falciparum (PF). Fifteen patients fulfilled the criteria for study of which 7 were DCM and 8 belonged to PCM group. Twelve (80%) were in school-going age group and M : F ratio was 2 : 1. All patients presented with fever, and CNS involvement, 66.6% had convulsion, 7 developed coma, anaemia was seen in 60%, but only 20% required blood transfusion. Splenomegaly and hepatomegaly was seen in 53.3% and 47% cases respectively. Two patients died, one each in DCM and PCM. Cerebral malaria is a serious complication of severe falciparum malaria and is seen in approximately 32% of PF positive cases.
CONCLUSION: PCM is an entity which should be kept in mind when treating fever without definite focus in rural areas, because timely and specific therapy is lifesaving.
