Presence of endotoxemia and its relationship to liver dysfunction in patients with typhoid fever.
Twenty-one patients with typhoid fever were studied to evaluate the presence of endotoxin in peripheral blood and its relationship to the incidence and features of hepatic dysfunction which may occur during this disease. The limulus test for endotoxin was positive in the plasma samples of all patients prior to treatment. Liver dysfunction, as assessed by fasting and postprandial serum bile acid levels and by standard biochemical tests, occurred in 90% of patients. In seven, the injury was purely cholestatic (elevation of postprandial serum bile acid levels, alone); in 12, it was of mixed cholestatic-hepatocellular type (elevation of both serum bile acids and aminotransferase levels). After recovering, the limulus test was negative and liver function tests returned to normal values in all patients. The results demonstrate that endotoxemia is present in patients with typhoid fever. In addition, since endotoxin can impair bile secretion, our results suggest that endotoxin may have a pathogenetic role in the development of liver injury during typhoid fever.
