Carbohydrate metabolism on high dose growth hormone therapy in children treated for leukaemia.
The effect on carbohydrate metabolism of a high dose growth hormone (GH) regimen (1.2 U/kg per week) was assessed on 24 children who had previously been treated for leukaemia. Sixteen patients received high dose GH and eight patients received a conventional dose of GH (0.6 U/kg per week). Oral glucose tolerance tests (OGTT) were performed at baseline and after 3 months of treatment with GH. For the entire group between 0 and 3 months, there was a significant increase in mean (and standard deviation) fasting plasma glucose (0.3 +/- 0.6 mmol/L), fasting insulin level (11 +/- 26 mU/L), and 2 h insulin level (20 +/- 40 mU/L). One patient, who received a conventional dose of GH, developed substantial carbohydrate intolerance. For the entire group, there was no change in response to a carbohydrate load at 3 months as measured by the area under the plasma glucose or insulin curve. There was no significant difference between conventional and high dose groups at 3 months as assessed by these parameters. This study demonstrates that a higher dose of GH may be used in these children in an attempt to improve their final height, without increased risk of carbohydrate intolerance in the short term.
