GH therapy can increase short-term growth and improve ( near ) final height .
Increases in height are such that treated individuals remain relatively short when compared with peers of normal stature .
BACKGROUND Idiopathic short stature ( ISS ) refers to children who are very short compared with their peers for unknown or hereditary reasons .
Recombinant human growth hormone ( GH ) has been used to increase growth and final height in children with ISS .
OBJECTIVES To assess the effects of recombinant human GH on short-term growth and final height in children with ISS .
Growth response of children with non-growth-hormone deficiency and marked short stature during three years of growth hormone therapy.
Short-term administration of human growth hormone to children with idiopathic short stature can improve mean growth rate and predicted adult height . It is yet unknown whether therapy would alter pubertal development or affect final height . Three-year treatment results in a group of children with idiopathic short stature are reported . For year 1 of the study , 121 prepubertal children were r and omly selected to receive somatotropin , 0.3 mg/kg per week , administered subcutaneously three times weekly ( n = 63 ) , or to be nontreatment control subjects ( n = 58 ) . After 1 year , all subjects were again r and omly selected to receive either three-times-weekly or daily dosing at the same total dose . For the 92 subjects who completed 36 months of treatment , mean growth rate increased from a mean of 4.6 cm/yr before treatment to a mean of 8.0 cm/yr in the first year of treatment . Daily dosing result ed in a significantly faster mean growth rate ( 9.0 cm/yr ) than three-times-weekly dosing ( 7.8 cm/yr ) ( p = 0.0005 ) . Mean growth rates were 7.6 and 7.2 cm/yr during years 2 and 3 , respectively , and did not differ by dosing group . Mean st and ardized height for all subjects improved from -2.7 to -1.6 after 3 years . When the growth rate was st and ardized for bone age , however , subjects who remained prepubertal had a significantly greater gain in mean height SD score than subjects who became pubertal during that 3-year period ( p < 0.02 ) . Mean st and ardized Bayley-Pinneau predicted adult height SD score increased from -2.7 to -1.6 and was independent of the timing of pubertal onset , but for individuals this score was more variable . Year-1 growth response , expressed as growth rate or change in height SD score , was the best predictor of growth in subsequent years . Responses to therapy could not be reliably predicted from baseline anthropometric variables , plasma insulin-like growth factor I SD score , growth hormone levels . Final height assessment will be needed to determine the ultimate benefit of therapy
