Skeletal maturity was not accelerated by treatment with recombinant growth hormone ( hGH ) .
BACKGROUND Turner syndrome ( TS ) affects about one in 1500 to 2500 live-born females .
One of the most prevalent and salient features of the syndrome is extremely short stature .
Untreated women are approximately 20 to 21 cm shorter than normal women within their respective population s. Recombinant human growth hormone ( hGH ) has been used to increase growth and final height in girls who have Turner syndrome .
OBJECTIVES To assess the effects of recombinant growth hormone in children and adolescents with TS .
Final height in girls with Turner’s syndrome treated with once or twice daily growth hormone injections
OBJECTIVES To study final height in girls with Turner ’s syndrome treated with once or twice daily injections of growth hormone ( GH ) in combination with low dose ethinyl oestradiol . DESIGN Until final height was reached , the effect of fractionated subcutaneous injections given twice daily was compared with once daily injections of a total GH dose of 6 IU/m2/day . Twice daily injections were given as one third in the morning and two thirds at bedtime . All girls concurrently received low dose oestradiol ( 0.05 μg ethinyl oestradiol/kg/day , increased to 0.10 μg/kg/day after 2.25 years ) . PATIENTS Nineteen girls with Turner ’s syndrome aged ⩾ 11 years ( mean ( SD ) 13.6 ( 1.7 ) years ) . MEASUREMENTS To determine final height gain , we assessed the difference between the attained final height and the final height predictions at the start of treatment . These final height predictions were calculated using the Bayley-Pinneau ( BP ) prediction method , the modified projected adult height ( mPAH ) , the modified index of potential height ( mIPHRUS ) , and the Turner ’s specific prediction method ( PTSRUS ) . RESULTS The gain in final height ( mean ( SD ) ) was not significantly different between the once daily and the twice daily regimens ( 7.6 ( 2.3 ) v 5.1 ( 3.2 ) cm ) . All girls exceeded their adult height prediction ( range , 1.6–12.3 cm ) . Thirteen of the 19 girls  had a final height gain > 5.0 cm . Mean ( SD ) attained final height was 155.5 ( 5.4 ) cm . A “ younger bone age ” at baseline and a higher increase in height st and ard deviation score for chronological age ( Dutch – Swedish – Danish references ) in the first year of GH treatment predicted a higher final height gain  after GH treatment . CONCLUSIONS Division of the total daily GH dose ( 6 IU/m2/day ) into two thirds in the evening and one third in the morning is not advantageous over the once daily GH regimen with respect to final height gain . Treatment with a GH dose of 6 IU/m2/day in combination with low dose oestrogens can result in a significant increase in adult height in girls with Turner ’s syndrome , even if they start GH treatment at a relatively late age
