Abstract

Adult Growth Hormone Deficiency (AGHD) is correlated to many adverse effects on metabolism and increased cardiovascular risk. Pregnancy-associated plasma protein-A (PAPP-A) is a protease that promotes IGF-I availability in vascular tissues in recent study, and PAPP-A levels have been proposed as an early predictor of cardiac events. The aim of our study was to compare PAPP-A levels in AGHD patients with that of healthy adult subjects to determine if there is a relationship between serum PAPP-A and glucose and lipid metabolism. Twenty AGHD patients and 20 healthy, age-matched and weight-matched persons were chosen for the study. Their weight, height, blood pressure, body mass index (BMI), body fat percentage, waist and hip circumference, and waist–hips ratio were assessed. An oral glucose tolerance test was performed and venous blood was collected from the each patient’s cubital vein for biochemical analysis. Serum PAPP-A level in AGHD patients was significantly higher than that of the control group [(7.62 ± 1.62 vs. 6.54 ± 1.31) p < 0.05], and PAPP-A was positively correlated to age, BMI, waist circumference and so on. After adjusting for the waist circumference, waist–hip ratio, 2 h postprandial blood glucose, triglycerides, the serum PAPP-A in AGHD patients was positively correlated to the BMI (r = 0.728, p < 0.05) and fasting insulin (r = 0.433, p < 0.05). In a multiple step-wise regression analysis, BMI, 2 h postprandial glucose, fasting insulin, HOMA-IR were independently associated with serum PAPP-A in AGHD patients. The increase in serum PAPP-A levels is associated with abnormal glucose metabolism and increased risk of atherosclerosis in AGHD patients.
