Composition of Bile after Orthotopic Liver Transplantation

Abstract

In 20 adult patients undergoing orthotopic liver transplantation (OLT), we studied longitudinally for the first 3 weeks after OLT the composition of bile with regard to differences between surviving and non-surviving patients and between patients with more or less rejection and the relation between bile and serum concentrations. The analyzed biliary components were bilirubin, cholesterol, bile acids, phospholipids, copper, iron, glucose, urea, creatinine, ammonia, protein, sodium, potassium, chloride, pH, bicarbonate, calcium and phosphate. After the 1st day the composition of bile was often different from reference values. In most patients deviations of the hepatic excretion function were found. Especially, a sharp fall was noticed in the biliary concentrations of cholesterol and copper. The composition of bile was not helpful in predicting the histologic degree of rejection or the ultimate outcome of the patients. Changes in bile glucose, electrolyte, urea, and creatinine concentrations were positively related to serum concentrations. We conclude that for the compounds analyzed the composition of bile after OLT is not only influenced by the state of the liver but also by the overall metabolic state of the patient.
