UNLABELLED: Homozygous familial hypercholesterolemia is an inherited metabolic disease that leads to decreased catabolism of low-density lipoprotein cholesterol. As a result coronary artery disease ensues by the first or second decade. Because most low-density lipoprotein receptors (50-75%) are located in the liver, liver transplantation has been introduced as a therapeutic option in this disorder. AIMS: To report our experience in the treatment of homozygous familial hypercholesterolemia with ortothopic liver transplantation. We evaluated metabolic results and patient survival. METHOD: We treated two affected siblings. One of them received a sequenced heart-liver transplantation because of cardiac failure due to severe coronary disease. RESULTS: The operative and postoperative course was favourable in both patients, with a decrease in cholesterol levels to normal values. Four years later both were alive and both had normal liver and heart functions. Neither patient needed cholesterol-lowering drugs, and the disease had not progressed. CONCLUSIONS: As shown by our results and those reported by others, liver transplantation is the treatment of choice for homozygous familial hypercholesterolemia until gene therapy becomes a viable option. Transplantation should be done before of cardiovascular complications develop.
