Long-term response to human growth hormone in 36 children with idiopathic growth hormone deficiency

Abstract

The results of long term treatment with human growth hormone (Crescormon^®, 12.4 IU/m²/week) in 36 patients with idiopathic growth hormone deficiency are given. Birth trauma—in particular assisted breech delivery (30%)—is the major aetiological cause. Twelve patients had isolated growth hormone deficiency (IGHD), 24 had multiple pituitary hormone deficiencies (MPHD) of which 19 were treated with additional thyroid hormones. The results were judged by the criteria of height velocity, total height gain and change of height prediction (TW₂, age based). It is concluded that the growth hormone dose chosen in many cases is insufficient to maintain high growth rates after the first year of treatment, when “catch-up” no longer takes place. The tendency of patients supplemented with thyroid hormone to grow better—without additional bone-age advancement—calls for careful search for hypothyroidism and suggests the use of thyroxin in cases of doubt.
