title: Is growth hormone a feasible adjuvant in the treatment of children after small bowel resection?
abstract: The aim of our study was to assess the metabolic consequences of short-term administration of growth hormone in children after gut resection and influence on polyamine production in red blood cells (RBC). Twelve children aged 4-60 months were studied. All children remained on parenteral nutrition and 11 also received oral feeding. Total non-protein energy intake was 429 +/- 86 kJ/kg body weight (BW)/day. Recombinant growth hormone (GH) was administered subcutaneously at a dose of 0.3 IU/kg BW/day for 10 days. Resting energy expenditure (REE; kJ/kg BW/day) was: 316.07 +/- 54.08 before and 346.04 +/- 54.40 during GH administration (P < 0.02), but daily weight gain before GH administration was significantly lower than during treatment. A significant increase of polyamine concentrations was observed in the RBC (spermidine: 30.1 +/- 15.1 and 43.8 +/- 24.9 nmol/ml packed RBC, P < 0.003; spermine: 15.6 +/- 5.1 and 19.6 +/- 10.6 nmol/ml packed RBC, P < 0.02) and in jejunal mucosa (spermidine: 172.10 +/- 142.35 nmol/g tissue and 193.92 +/- 108.15 nmol/g tissue). The authors concluded that increased polyamine concentrations in the RBC and jejunal mucosa reflect a cellular response to GH administration. The anabolic effect of GH results in higher weight gain, although increased REE may indicate increased energy requirements during GH treatment.
