REVIEW ER 'S CONCLUSIONS Recombinant human growth hormone ( hGH ) doses between 0.3 - 0.375 mg/kg/wk increase short-term growth in girls with Turner Syndrome ( TS ) by approximately 3 cm in the first year of treatment and by approximately 2 cm per year after 2 years of treatment .
There is little evidence on the effects of hGH on final height .
BACKGROUND Turner syndrome ( TS ) affects about one in 1,500 to 2,500 live-born females .
One of the most prevalent and salient features of the syndrome is extremely short stature .
Untreated women are approximately 20 - 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 women who have Turner syndrome .

Growth hormone and low dose estrogen in Turner syndrome: results of a United States multi-center trial to near-final height.
A cardinal clinical feature of Turner syndrome ( TS ) is linear growth failure result ing in extreme short stature : the median adult height of untreated women with TS is 143 cm , 20 cm ( 8 in . ) below that of the general female population . In the largest multicenter , r and omized , long-term , dose-response study conducted in the United States , 232 subjects with TS received either 0.27 or 0.36 mg/kg.wk of recombinant human GH with either low dose ethinyl E2 or oral placebo . The study was placebo-controlled for both GH and estrogen for the first 18 months and remained placebo-controlled for estrogen for its duration . The near-final height  of the 99 subjects whose bone age was at least 14 yr was 148.7 + /- 6.1 cm after 5.5 + /- 1.8 yr of GH started at a mean age of 10.9 + /- 2.3 yr ; this represents an average increase of 1.3 + /- 0.6 SD scores from baseline ( TS st and ard ) . Height was greater than 152.4 cm ( 60 in . ) in 29 % of subjects compared with the expected 5 % of untreated patients . Mean near-final heights of subjects who received the lower GH dose , with or without estrogen , were 145.1 + /- 5.4 and 149.9 + /- 6.0 cm , respectively ; those who received the higher GH dose with or without estrogen achieved mean near-final heights of 149.1 + /- 6.0 and 150.4 + /- 6.0 cm , respectively . Factors that most impacted outcome were younger age , lower bone age/chronological age ratio , lower body weight , and greater height SD score at study entry . This study demonstrates significant  GH-induced improvement in height SD score , with correction of height to within the normal channels for a significant number of patients , and provides evidence of a GH dose-response effect . These data also indicate that early administration of estrogen , even at relatively low doses , does not improve gain in near-final height in patients with TS
