title: Correlation of increased plasma osteoprotegerin and cardiovascular risk factors in patients with adult growth hormone deficiency.
abstract: Adult growth hormone deficiency (AGHD) is correlated to many adverse effects on metabolism and increases cardiovascular risk. 40 patients with AGHD and 40 healthy subjects were included. Anthropometric parameters such as body mass index, waist circumference, and waist-hip ratio were measured. Meanwhile, plasma levels of total cholesterol, triglyceride, high sensitivity C-relative protein, interleukin-6 and OPG were determined. Homeostasis model assessments for insulin resistance (HOMA-IR) and β-cell function (HOMA-β) were calculated using homeostasis model. Plasma OPG concentrations of AGHD patients were significantly higher than those in healthy subjects (131.82 ± 45.04 versus 81.02 ± 45.04, P < 0.01). Plasma OPG levels were positively correlated with age, body mass index, waist circumference, hip circumference, waist-hip ratio, fasting insulin, total cholesterol, triglyceride, high sensitivity C-relative protein and interleukin-6 (P < 0.05), but negatively correlated with high-density lipoprotein cholesterol (P < 0.05). Multiple linear stepwise regression analysis demonstrated that body mass index, triglyceride, and interleukin-6 were independently related to plasma OPG levels (P < 0.05). The levels of plasma OPG were increased in AGHD patients and were closely correlated with glycolipid metabolism and chronic inflammation. OPG might play an important role in the occurrence and development of cardiovascular diseases in AGHD patients.
