Objective: In this study, we aimed to show the role of ghrelin in growth delay in children with constitutional delay of growth and puberty (CDGP). Methods: Thirty male children with CDGP constituted the study group and fifteen healthy children with normal growth of similar ages-the control group. In both groups, fasting and postprandial plasma ghrelin levels, serum insulin-like growth factor-1 (IGF-1) and IGF-binding protein-3 (IGFBP-3) levels were determined. Results: There were no differences in fasting and postprandial ghrelin levels (824.23±523.46 pg/mL and 447.26±259.92 pg/mL, respectively) in children with CDGP compared to the levels in the control group (687.38±481.43 pg/mL and 365.59±260.43 pg/mL, respectively; p>0.05). Differences in fasting and postprandial ghrelin levels were also similar in the two groups (394.44±369.10 pg/mL and 346.55±338.67 pg/mL, respectively; p>0.05). Serum IGF-1 levels were significantly depressed in children with CDGP compared to those in the control group (239.5±83.95 ng/mL and 339.20±63.08 ng/mL, respectively; p |
