Opis:
This study investigated associations between the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis, adiponectin, resistin and metabolic profile in 47 GH-deficient children before and during 12 months of GH treatment. 23 short age-matched children without growth hormone deficiency (GHD) or any genetic or chronic disorders were recruited as controls at baseline. Metabolic evaluation included measurements of adiponectin, resistin, IGF-1, total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), glucose, insulin, glycated haemoglobin (HbA1c), thyroid stimulating hormone (TSH) and free thyroxine (free T4) concentrations. The GH-deficient children had significantly higher adiponectin (p<0.05) and total cholesterol (p<0.05) levels, and a significantly lower level of resistin (p<0.05) than the controls. Resistin at 6 months of GH treatment significantly correlated with changes in height SDS in that period (r=0.35) and with the level of fasting insulin (r=0.50), the HOMA-IR (r=0.56) and the QUICKI (r=-0.53) at 12 months of therapy. Adiponectin level at 12 months of GH treatment was significantly associated with changes in HDL-C within the first 6 (r=0.73) and within 12 (r=0.56) months of therapy, while resistin significantly correlated with an increment in IGF-1 within 12 months of treatment (r=0.49) and with total-C at 12 months (r=0.56). Untreated GH-deficient children had higher adiponectin and lower resistin levels than healthy short children without GHD. Adiponectin and resistin levels did not change significantly during the first 12 months of GH therapy. Good responders to GH treatment had a tendency for higher resistin level during GH therapy, which positively correlates with the insulin resistance parameters.

Opis:
The relationships between bone turnover, the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and vitamin D are complex, but still not fully explained. The GH/IGF-1 axis and vitamin D can mutually modulate each other's metabolism and influence the activation of cell proliferation, maturation, and mineralization as well as bone resorption. The aim of this study was to evaluate the reciprocal associations between bone formation markers [alkaline phosphatase (ALP), bone alkaline phosphatase (BALP)], the GH/IGF-1 axis and 25-hydroxyvitamin D [25(OH)D] in children with growth hormone deficiency at baseline and during recombinant human growth hormone (rhGH) therapy. ALP, BALP, 25(OH)D and IGF-1 levels were evaluated in 53 patients included in this prospective three-year study. ALP, BALP and IGF-1 increased during rhGH therapy. Baseline ALP activity correlated positively with baseline height velocity (HV). ALP and BALP activity at 12 months correlated positively with HV in the first year of therapy. We found positive correlations between ALP and IGF-1 at baseline and during the first year of therapy, between BALP activity at 12 months and rhGH dose in the first year of therapy, and between doses of cholecalciferol in the first year of rhGH therapy and early changes in BALP activity during rhGH therapy. Our results indicate that vitamin D supplementation enhances the effect of rhGH on bone formation process, which could improve the effects of rhGH therapy. ALP and BALP activity are useful in the early prediction of the effects of rhGH therapy, but their utility as long-term predictors seemed insufficient.
