Growth hormone deficiency and growth hormone therapy in Ullrich-Turner-syndrome.

In a girl with Ullrich-Turner-Syndrome (gonadal dysgenesis 45, XO) and growth hormone deficiency, 10 U of human growth hormone/m2 body surface area/week increased the growth rate from 2.0 to 4.1 cm/year. Doses of up to 36 U/m2/week did not improve the growth rate in 4 girls with Ullrich-Turner-Syndrome who had normal plasma growth hormone concentration and increation. We conclude that growth hormone therapy is unsuccessful in dwarfism in Ullrich-Turner-Syndrome and should be reserved for patients with proven growth hormone deficiency.
