[Lipid profile and alteration of body composition in growth hormone deficient adults].

Background: The growth hormone deficiency (GHD) syndrome in adults and the increased associated cardiovascular risk have been extensively studied in recent years. Abnormal body composition with excess of visceral adiposity and adverse lipid profile are important features of this syndrome. Abnormal lipid profile has been described with increased levels of total cholesterol (C), LDL-cholesterol (LDL-C), triglycerides, decreased levels of HDL-cholesterol (HDL-C) and apolipoproteins abnormalities.

Methods: Lipid profile and the amount of visceral adipose tissue were studied in 31 GHD adults compared with a control group of healthy subjects matched for age, gender and body mass index (BMI). Visceral adipose tissue was evaluated by abdominal computed tomography and anthropometric measurements--BMI (kg/m2) and waist circumference (cm). The lipid profile was studied by measurement of C, LDL-C, HDL-C, triglycerides, apolipoproteins A and B, and Lipoprotein (a).

Results: The GHD adults showed increased visceral adipose tissue (156.66 +/- 72.72 vs. 113.51 +/- 32.97 cm2, p = 0.049), higher levels of triglycerides (158.58 +/- 80.29 vs. 97.17 +/- 12.37 mg/dl; p = 0.007) and lower HDL- cholesterol (45.41 +/- 13.30 vs. 55.34 +/- 14.31 mg/dl; p = 0.002). There were no differences in others aspects of lipid profile and anthropometric measurements.

Conclusion: Growth Hormone Deficient adults showed increased visceral adipose tissue, higher levels of triglycerides and lower HDL- cholesterol levels.
