title: Liver transplantation restores low serum levels of very low density and high density lipoproteins in end-stage primary biliary cirrhosis.
abstract: Amounts of serum lipids were determined in 10 women suffering from end-stage primary biliary cirrhosis (PBC) in order to evaluate the concentrations of and changes in very low density (VLDL), high density (HDL) lipoprotein cholesterol and apoprotein A-I before and after liver transplantation. The concentrations of some preoperative serum total lipids, especially HDL cholesterol and VLDL triglyceride, and apoprotein A-I, were significantly lower, but those of serum total triglycerides and cholestanol (a metabolite of cholesterol) were higher in the PBC patients than in 12 controls matched for age, sex, and body mass index. The relation between the serum concentrations of HDL cholesterol and cholestanol was markedly different before transplantation in the PBC group and in the control group. Liver transplantation was followed by a significant and rapid increase in serum apoprotein A-I and HDL cholesterol concentrations, which were affected by CMV and Klebsiella infections and acute rejections and immunosuppressive treatments. As a result the patients serum values did not quite return to normal during the three month follow up. The concentrations of serum VLDL cholesterol, triglycerides and cholestanol returned to normal during the follow up, and the changes in cholestanol were inversely related to the increases in amounts of HDL cholesterol. Thus, the restoration of low HDL concentrations after liver transplantation suggests that the liver plays a key role in HDL metabolism and indicates that concentrations of serum HDL cholesterol may be useful in monitoring the recovery of liver function.
