Pubertal Development During GH Treatment with or without Additional GnRH Analogue Treatment in Short Children Born Small for Gestational Age

van der Steen M , Lem A J , Hokken-Koelega A C S

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

Response to GH Treatment in Patients with Silver Russell Syndrome

Smeets C C J , Renes J S , van der Steen M , Hokken-Koelega A C S

Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...
