title: Demography, auxology and response to recombinant human growth hormone treatment in girls with Turner's syndrome in the Kabi Pharmacia International Growth Study. International Board of the Kabi Pharmacia International Growth Study.
abstract: Demographic and auxological data were analysed from 818 girls with Turner's syndrome treated with recombinant human growth hormone (GH) and entered into the Kabi Pharmacia International Growth Study. Size at birth was low and correlated with the heights of both parents. The median age at start of GH treatment was 11.4 years and the parents had a median height SDS of -2.9. Height SDS at the start of treatment correlated with parental heights. Height velocities conformed to Turner-specific standards. The weight-for-height index increased sharply above 9 years of age. The frequency of spontaneous appearance of Tanner breast stage 2 was high (34.1% of girls > 10 years of age). Bone age (Greulich and Pyle) data were described by the equation: bone age = 1.61(chronological age) - 0.04(chronological age)2 - 3.61. This equation was used to correct adult height predictions. The median initial dose of GH was 0.8 IU/kg/week and was maintained during the first 3 years of treatment. The median frequency of injections was six/week. Height velocity increased from 4.1 to 6.8 cm/year in the first year, and height velocity SDS for chronological age remained positive for 4 years. The height prediction corrected for bone age increased over the first 2 years only. Differences in demography and auxology were described according to karyotype and country of origin. A greater height velocity SDS was observed at higher GH doses and when oxandrolone was used concomitantly.
