Colestipol plus nicotinic acid in treatment of heterozygous familial hypercholesterolaemia.
Thriteen patients with heterozygous familial hypercholesterolaemia (FH) were sequentially treated with: a low-cholesterol, fat-restricted diet; diet and colestipol; and diet and colestipol and nicotinic acid. Concentrations of plasma cholesterol decreased from 415 +/- 69 mg/dl on diet alone to 327 +/- 54 mg/dl on colestipol and fell to 246 +/- 49 mg/dl on the combined drug regimen. Plasma concentrations of LDL cholesterol declined 24% on colestipol; the subsequent addition of nicotinic acid resulted in a further 31% fall so that values on the combined drug regimen were 47% below those seen on diet alone. HDL cholesterol levels were similar on both the diet (40 mg/dl) and colestipol (43 mg/dl) treatment periods but increased to 53 mg/dl on the combined drug regimen. Treatment resulted in significant decreases in the LDL:HDL ratio which fell from 8.4 on diet to 3.3 on the colestipol plus nicotinic acid regimen. In most patients with heterozygous FH, combined use of a bile acid sequestrant and nicotinic acid affords the opportunity to maintain a normal lipid profile. Prolonged use of this regimen may reduce the incidence of premature coronary atherosclerosis which naturally occurs in these patients.
