This is prospective cross-sectional study on 37 patients presenting to different hospitals in Khartoum state, Sudan, sought to determine the etiology, clinical course, and predictors of mortality in patients presenting with fulminant hepatic failure (FHF). Patients were subclassified into hyperacute, acute, and subacute FHF; all sera were tested for hepatitis A, B, C, and E; negative samples were tested for antinuclear antibodies and anti-smooth muscle antibodies. The commonest etiologic factors included seronegative hepatitis (38%), hepatitis B virus (22%), severe Plasmodium falciparum malaria (8%), autoimmune hepatitis (8%), hepatitis E virus (5%), anti-tuberculous drugs (5%), and lymphomatous infiltration of the liver (5%). The mortality rate was high at 84%. Poor prognostic factors included presentation with grade III/IV encephalopathy, evidence of bacterial infection, and a prolonged prothrombin time of >25 seconds over the controls.
