INTRODUCTION: Severe malaria due to P. vivax infection is increasingly observed now a days. Organ failure in vivax malaria is caused by mechanisms of inflammation as well as sequestration. In this study we have compared the complications in vivax malaria with those in falciparum or mixed malaria. AIMS AND OBJECTIVES: 1) To study various complications in adult inpatients of vivax malaria. 2) To compare the incidence of complications in vivax, falciparum and mixed malaria. MATERIALS AND METHODS: This was a retrospective observational study done at a tertiary care hospital in Mumbai over 3 months period. All adult indoor patients positive for malarial infection based on peripheral smear or malarial antigen (LDH) spot test were included in the study. Their demographic profile, complications, course in ward till discharge or death was noted. Data was analysed using appropriate statistical tests. RESULTS: 680 cases of malaria were included in the study. 338 were infected with P. vivax, 206 with P. falciparum, 136 with mixed infection. Severe disease was present in 162 (23.82%) cases of malaria of which 50 (31%) had vivax infection, 64 (39%) had falciparum infection and 48 (30%) had mixed infection. The complications seen in vivax malaria were: thrombocytopenia (68%), leukopenia (19%), ARDS (3%), high bilirubin (5%), acute renal failure (3.5%), anemia (3%), mucosal bleeding (8%), cerebral malaria (3.5%), hypotension (5%), metabolic acidosis (4%) and death (1.77%). CONCLUSIONS: 31% cases of severe malaria had vivax monoinfection. Thrombocytopenia, leukopenia, acute respiratory distress syndrome, hypotension, mucosal bleeding were seen as frequently as in falciparum and mixed malaria. Acute renal failure, cerebral malaria, high bilirubin, anaemia, metabolic acidosis and death were also found in vivax malaria but less frequently than in falciparum and mixed malaria.
