Abstract
BackgroundGnRH analogue (GnRHa) combined with GH treatment has been proposed to increase adult height. Effect on metabolic profile and GH, IGF1, and IGFBP3 levels in short small for gestational age (SGA) children is unknown.ObjectiveTo assess fat mass and lean body mass SDS, percentage trunk fat, blood pressure (BP), insulin sensitivity (Si), β-cell function (disposition index, DI), lipid profile, and GH, IGF1, and IGFBP3 levels during 2 years of combined treatment.SubjectsForty-one pubertal short SGA children with a mean (±s.d.) age of 12.1 (±1.0) years.DesignChildren received 3.75 mg of leuprolide acetate depot subcutaneously every 4 weeks, and they were randomly assigned to receive 1 mg (group A) or 2 mg (group B) of GH/m2per day.ResultsPercentage trunk fat increased in both groups, but to a lower extent in group B. Lean body mass SDS increased only in group B. Changes in BP, Si, DI, and lipids were similar in both groups. Si significantly decreased, but DI remained unchanged. Lipids remained normal. GH and IGF1 levels were significantly higher in group B.ConclusionOur study is the first to report that 2 years of combined treatment with a GnRHa and either 1 or 2 mg GH/m2per day does not adversely affect body composition and metabolic profile of short SGA children who come under medical attention at the onset of puberty. There was a dose-dependent effect on fat mass SDSheight, percentage trunk fat, lean body mass SDSheight, and GH and IGF1 levels in favor of treatment with GnRHa and the higher GH dose of 2 mg/m2per day.
