OBJECTIVE: To determine whether peripheral inflammatory and fibrinolytic markers are elevated in growth hormone-deficient (GHD) adolescents and associated with increased postprandial lipoproteins. STUDY DESIGN: Fifteen GHD children on GH treatment with a chronologic age of 12.7 +/- 2.5 years and 10 untreated GHD adolescents with a chronologic age of 13.0 +/- 2.6 years were studied. Triglycerides (TG), C-reactive protein (CRP), fibrinogen, interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-alpha) were measured in the fasting state and 4 hours after ingesting a high-fat meal; 15 healthy adolescents served as controls. RESULTS: Fasting and postprandial TG of untreated GHD children were higher than those in treated subjects and healthy controls. Fasting TNF-alpha, CRP, and fibrinogen concentrations of untreated GHD adolescents were higher than those in healthy controls, but similar to those of GH-treated GHD adolescents. Although fibrinogen levels increased after a high-fat meal in GHD adolescents, CRP, TNF-alpha, and IL-6 concentrations did not increase further. Fasting and postprandial TG of untreated GHD adolescents were positively associated with fasting and postprandial CRP, and with postprandial TNF-alpha and IL-6 concentrations. Fasting TG also correlated positively with fasting fibrinogen concentrations in untreated and treated GHD adolescents. CONCLUSIONS: The pronounced inflammatory response seen in GHD adolescents seems to be associated with the presence of elevated levels of fasting and postprandial TG, which may result in an increased susceptibility for premature atherosclerosis.
