BACKGROUND: Malaria is of immense importance amongst the tropical diseases in India. There is a need to develop newer diagnostic aids and research is necessary to identify new prognostic markers for prediction of the course and complications.
AIMS: To evaluate the white cell differential count and morphology in Plasmodium vivax and Plasmodium falciparum malaria and study their prognostic utility.
SUBJECTS AND METHODS: Two hundred and sixty-four adult patients in the age range of 20 to 65 years presenting to the hospital over a period of 4 months with clinical features of malaria and a positive peripheral smear examination were studied.
RESULTS: No statistically significant difference was noted in the white blood cell (WBC) count and neutrophil count in P.vivax versus P. falciparum malaria. Band cells were more frequently noted in P. falciparum malaria than in P.vivax malaria (p < 0.0001). Toxic granulation of the neutrophils was noted in 9.5% of the patients and exclusively in P. falciparum malaria. Presence of toxic granulation of the polymorphs in subjects with P. falciparum malaria was significantly associated with anaemia (p=0.019), jaundice, cerebral involvement, adult respiratory distress syndromes, renal dysfunction and death (p < 0.0001 for all these parameters).
CONCLUSION: Band cells were seen in P. vivax and P. falciparum malaria, although in higher numbers in P. falciparum malaria. Toxic granulation of the neutrophils was noted only in the presence of P. falciparum malaria in this study and correlated with severity.
