CORRELATION OF INCREASED SERUM ADIPSIN WITH INCREASED CARDIOVASCULAR RISKS IN ADULT PATIENTS WITH GROWTH HORMONE DEFICIENCY.

Adult growth hormone deficiency (AGHD) patients have an increased cardiovascular morbidity and mortality. Adipsin is an adipokine that is significantly correlated with metabolic disease, especially in people with obesity. The objective of our study was to compare AGHD patients with healthy subjects to evaluate whether adipsin levels are closely related to glycolipid metabolism and cardiovascular risks in AGHD patients. Our study included 88 AGHD patients and 88 age-, weight-, and body mass index (BMI)-matched healthy subjects. Anthropometric parameters such as BMI, waist circumference, and blood pressure were measured. Biochemical indicators such as serum adipsin, lipids, and fasting insulin levels were determined. Adipsin levels in AGHD patients were significantly increased compared to levels of the control group (11,567.29 ng/mL, interquartile [9,856.46 to 13,360.60 ng/mL]) versus (9,127.86 ng/mL, interquartile [8,061.82 to 10,647.06 ng/mL], = .000). Increased serum adipsin levels are correlated with cardiovascular risk factors such as a higher waist-to-hip ratio, serum lipids levels, and insulin resistance. Adipsin levels were inversely related to insulin-like growth factor 1 (IGF-1) (r = -0.6363, <.0001) and insulin-like growth factor binding protein 3 levels (r = -0.498, <.0001). The odds ratio (OR) for AGHD in the highest quartile was found to be 4.491 times the ratio in the lowest quartile (OR = 4.491, = .048). Additionally, adipsin was found to be the most independent factor to influence IGF-1 levels in AGHD subjects. The serum levels of adipsin were significantly correlated with glucolipid metabolism disorder with a growth hormone deficiency status. Furthermore, serum levels of adipsin might be a good marker for the occurrence and development of cardiovascular diseases in AGHD patients. = adult growth hormone deficiency; = atherosclerotic cardiovascular disease; = body mass index; = diastolic blood pressure; = fasting insulin; = fasting plasma glucose; = growth hormone; = homeostatic model to assess insulin resistance index; = high-sensitivity C-reactive protein; = insulin-like growth factor 1; = insulin-like growth factor binding protein 3; = lipid accumulation products; = low-density lipoprotein; = systolic blood pressure; = total cholesterol; = triglycerides; = waist circumference; = waist-to-hip ratio; = odds ratio.
