| Abstract: | Twenty-one patients with pituitary dwarfism were treated with methionine-free hGH (r-hGH) for 6 months with a dosage of 0.5 IU/kg/week. The height of newly treated patients (N = 14), increased from 2.4 to 5.0 cm during treatment, which corresponded to from 4.8 to 10.0 cm with a mean of 8.1 +/- 0.5 cm/year. In switched patients (N = 7), height increased from 2.2 to 3.8 cm during the treatment, which corresponded to 4.4-7.6 cm with a mean of 6.1 +/- 0.5 cm/year, which was similar to that observed in previous treatment with pituitary extracted hGH (p-hGH). Anti-hGH antibody was observed in two patients (9.5%) at the end of 6 months of treatment with a titer of 10. These data indicate that r-hGH has a growth promoting effect and low antigenicity. |
