Serum lipids in acromegaly.
Serum cholesterol and triglyceride concentrations were determined in 46 patients with active acromegaly but with otherwise intact pituitary function. The mean serum-cholesterol level of the patients was lower and the mean serum-triglyceride higher than in the basic population of comparable age. The incidence of hypercholesterolemia was similar to that in general population, whereas the incidence of type IV hypertriglyceridemia was almost three times higher than in control population. The serum triglyceride level was not related to relative body weight, basal serum growth hormone, or insulin concentrations, nor did it correlate with glucose tolerance or with plasma-insulin response to oral glucose. However, the patients with highest plasma-insulin response had significantly higher serum triglyceride than the rest of the acromegalic group. The endogenous serum-triglyceride turnover rate showed no consistent changes, but increased serum triglyceride was associated with increased production rate. Upon successful surgical treatment of the acromegaly, serum-triglyceride level decreased in most of the cases who initially had hypertriglyceridemia. It is concluded that acromeagaly can give rise to moderate secondary hypertriglyceridemia.
