AUTHORS ' CONCLUSIONS Addition of ox and rolone to the GH therapy led to a modest increase in the final adult height of girls aged up to 18 years with TS .
BACKGROUND The final adult height of untreated girls aged up to 18 years with Turner syndrome ( TS ) is approximately 20 cm shorter compared with healthy females .
Treatment with growth hormone ( GH ) increases the adult height of people with TS .
The effects of adding the and rogen , ox and rolone , in addition to GH are unclear .
Therefore , we conducted this systematic review to investigate the benefits and harms of ox and rolone as an adjuvant therapy for people with TS treated with GH .
OBJECTIVES To assess the effects of ox and rolone on growth hormone-treated girls aged up to 18 years with Turner syndrome .
Growth promotion and Turner-specific bone age after therapy with growth hormone and in combination with oxandrolone: when should therapy be started in Turner syndrome?
The aims of this comparative multicenter study of 67 girls with Turner syndrome ( TS ) on three different therapeutical regimens were , first , to evaluate the effect of either recombinant human growth hormone ( GH ) alone or in combination with the anabolic steroid ox and rolone ( Oxa ) on height velocity and on Turner-specific bone age ( BA'TS ) and , second , to estimate the gain in final height taking the age at the onset of treatment into account . The mean advancement of BA'TS in 2 years of treatment was 2.5 years/2 years in group 1 ( low dose GH : 16 IU/m2/week ) , 2.8 years/2 years in group 2 ( high dose GH : 28 IU/m2/week ) and 3.3 years/2 years in group 3 ( GH : 24 IU/m2/week + Oxa : 0.06 mg/kg/day ) instead of the expected 2 years/2 years advancement in untreated girls with TS . On all treatment regimens the advancement of BA'TS was more pronounced in the younger girls . In many girls with a BA'TS below 9 years at the onset of treatment the increase in height did not outweigh the advancement in BA'TS , suggesting that starting growth-promoting treatment before 9 years would not be the best way to improve final height . In our opinion , the optimal age for starting growth-promoting therapy is at 9 years . A start at a younger age might have no advantage in regard of an ultimate gain in final height . On the other h and , therapy should not be delayed much after the age of 9 years giving the girls with TS the possibility to catch up substantially before estrogen treatment is initiated
