    Journal: Acta Trop; 2011 Feb; 117(2):82-5. PubMed ID: 20943199.
    Abstract:
    INTRODUCTION: despite the high prevalence of Plasmodium vivax (P vivax) malaria, research into its complications has lagged disproportionately as compared to Plasmodium falciparum (P falciparum) malaria. MATERIAL AND METHODS: the present retrospective observational study was conducted on cases with P vivax mono-infection presenting with severe malaria on the basis of one or more criteria as per the World Health Organization guidelines being used for severe falciparum malaria in children, as well as other manifestations been classified as complicated malaria, during an outbreak of malaria in a single tertiary referral hospital of north India. RESULTS: seventy-four patients of acute malaria presented during the outbreak, of which 50 cases with P vivax mono-infection were included for the study. Complicated malaria was diagnosed in 41/50 cases, with thrombocytopenia being the commonest manifestation. Other presentations of severe malaria in our patients were liver dysfunction (with or without jaundice) 31/50 cases, respiratory involvement 14/50 cases, renal impairment 11/50 cases, circulatory collapse (Shock) 8/50 cases, severe anaemia 3/50 cases and central nervous system (CNS) involvement 2/50 cases. CONCLUSION: the term "benign tertian malaria" no longer holds true for P vivax mono-infection. The authors wish to open a new front for researches on the possible genotypic abnormalities that the parasite or its carrier might have acquired over decades and has transformed into a species with the malignant potential of P falciparum.
