title: Malarial hepatopathy: Clinical profile and association with other malarial complications.
abstract: This prospective study assessed the incidence, clinical profile and outcome of malarial hepatopathy and its association with other complications in patients with malaria, proved by peripheral blood smear examination and rapid malaria test. Hyperbilirubinemia (Serum bilirubin >3mg/dL) with >3-fold rise in serum aminotransferases in absence of a different explanation for such derangement was considered as malarial hepatopathy. Of 134 (falciparum-81, vivax-48 and mixed falciparum and vivax-5) malaria cases, hyperbilirubinemia occurred in 41.04%. Serum aspartate aminotransferase (AST) was raised >3-fold in 17.16% and serum alanine aminotransferase (ALT) in 4.47% cases. Malarial hepatopathy was observed in 4.47% (falciparum-5 and vivax malaria-1) cases, but had insignificant association with the type of malaria (p=0.532). Serum bilirubin, AST and ALT levels were higher while age was lower in both overall (p<0.05 each) and falciparum malaria cases with hepatopathy than without hepatopathy (p<0.05 each). Malarial hepatopathy was associated with a higher incidence of cerebral malaria, shock, acute respiratory distress syndrome (ARDS) and acute kidney injury in both overall (p<0.05 each) and falciparum malaria (p<0.05 each) and hyponatremia and disseminated intravascular coagulation only in overall malaria (p<0.05). Malarial hepatopathy had significant association with duration of hospitalization, parasite clearance time, fever clearance time and jaundice clearance time in overall (p<0.05 each) and falciparum (p<0.05 each) but not vivax malaria cases (p>0.05 each). Mortality occurred in 1 (20%) case of falciparum-induced hepatopathy with an overall mortality of 16.66%. ARDS (p=0.003) and shock (p=0.026) were independently associated with malarial hepatopathy overall while only ARDS with falciparum-induced hepatopathy (p=0.006). Thus, hepatocellular dysfunction is common in malaria but that qualifying as malarial hepatopathy is not common. Malarial hepatopathy is likely to occur in presence of other malarial complications. It is an epiphenomenon in severe malaria and indicative of severe disease. Establishing a particular association with malaria or mortality would require a larger case-control study of severe malaria.
