Abstract
Two patients with nomozygous familial hypercholesterolemia, refractory to medical therapy, underwent complete bile diversion by common-duct ligation and cholecystostomy, in an attempt to arrest the progression of their xanthomatosis and atherosclerosis by depletion of body cholesterol. Clofibrate was given after operation to one patient, and cholic acid to both, in an effort to enhance further the negative sterol balance. Bile diversion produced an increase of six to eight times in gastrointestinal sterol output, which was not increased further by either clofibrate or cholic acid therapy. Despite a calculated sterol loss of 560 g over 14 months in one patient and 400 g over 10 months in the other, neither plasma cholesterol nor xanthoma size decreased. Continuity of the biliary tree was therefore restored. The data suggest that patients with homozygous familial hypercholesterolemia respond to even massive gastrointestinal sterol depletion with equal increases in sterol synthesis.Keywords
