Evaluation of serum uric acid to creatinine ratio in fulminant hepatitis.

Of the eight patients with fulminant hepatitis placed under total parenteral nutrition with an amino acid solution rich in branched chain amino acids and treated by plasma exchange, four survived and four died from hepatic failure. Serum uric acid levels in the non-survived group were significantly lower on days 1-6 compared with the survived group. The concentration ratios of uric acid to creatinine and prothrombin time were significantly lower on days 5-8 and days 3-8, respectively, in a similar comparison. Thus, the uric acid to creatinine ratio, which corrects for the possible renal dysfunction associated with acute hepatic failure, may serve as a clinically useful prognostic indicator for patients with fulminant hepatitis.
