[Influence of serum IGF-I and testosterone on lipid and glycemic profile in acromegalic men].

OBJECTIVES To evaluate the influence of IGF-I and testosterone on the lipid profile and glycemia in acromegalic men. METHODS Fifteen acromegalic men were studied. RESULTS The hypogonadic patients presented lower HDL-c and higher tryglicerides, LDL-c, glycemia, GH and IGF-I. Serum IGF-I was inversely correlated with HDL-c (r = - 0.57, p = 0.04) and directly with TG (r = 0.62, p = 0.01) and glycemia (r = 0.66, p = 0.008), whereas serum testosterone correlated directly with HDL-c (r = 0.52, p = 0.05) and inversely with TG (r = - 0.57, p = 0.02), LDL-c (r = - 0.53, p = 0.04) and fasting blood glucose (r = - 0.54, p = 0.03). IGF-I and testosterone were inversely correlated (r = - 0.585, p = 0.028). CONCLUSION These results suggest that the most important intervention in reducing cardiovascular risk in these patients is to control the activity of the disease.
