title: Methionyl human growth hormone and oxandrolone in Turner syndrome: preliminary results of a prospective randomized trial.
abstract: Seventy girls with Turner syndrome, 4 to 12 years of age, were randomly assigned to receive either no treatment (control) or methionyl human growth hormone (0.125 mg/kg three times per week), oxandrolone (0.125 mg/kg/day), or combination hGH plus oxandrolone therapy. Baseline growth rates averaged 4.3 cm/yr, and all were within 2 SD of mean growth velocity for age in girls with Turner syndrome. Sixty-seven girls remained in the study for a minimum of 1 year. Growth rates and growth velocity (in standard deviations for age in girls with Turner syndrome) were control 3.8 cm/yr (-0.1 SD), hGH 6.6 cm/yr (+2.3 SD), oxandrolone 7.9 cm/yr (+3.7 SD), and combination therapy 9.8 cm/yr (+5.4 SD). Mean bone ages advanced 1.0 years (hGH), 1.3 years (oxandrolone), and 1.6 years (combination). However, median increments in height age/bone age (delta HA/delta BA) ratios ranged from 1.0 to 1.1 for treatment groups, compared with 0.8 for the controls. Predicted adult height by the method of Bayley-Pinneau increased 2.5 cm for hGH or oxandrolone alone, and 3.2 cm for combination treatment. These data indicate that both hGH and oxandrolone can significantly stimulate short-term skeletal growth in patients with Turner syndrome, and potentially increase final adult height.
