One-year treatment with recombinant human growth hormone of children with meningomyelocele and growth hormone deficiency: a comparison of supine length and arm span.

Growth retardation and precocious puberty are frequently found in children with meningomyelocele (MMC). Lower limb contractions, spasticity and kyphoscoliosis may lead to disproportionate short stature. Most of these patients have structural brain defects or hydrocephalus which can cause growth hormone deficiency. In this study, 19 children aged between 3.5 and 12.8 years with MMC and growth hormone (GH) deficiency were treated with recombinant human GH for a period of 12 months. Supine length, arm span and growth velocity were compared before, and after 6 and 12 months of treatment with rhGH (daily dose 2.0 IU/m2 BSA s.c.). Mean supine length standard deviation score (SDS) increased by +0.8 SDS after 6 months and +1.2 SDS after 12 months of therapy. Mean arm span standard deviation score increased by +0.9 SDS and +1.3 SDS. Growth velocity increased in supine length from 3.3 cm/yr (-2.1 SDS) to 8.4 cm/yr (+2.4 SDS) and in arm span from 4.8 cm/yr (-1.3 SDS) to 8.6 cm/yr (+3.1 SDS) in the first 6 months and was 8.1 cm/yr (+2.4 SDS) and 8.3 cm/yr (+2.6 SDS) after 12 months of therapy. Linear correlation between SDS growth velocity supine length and SDS growth velocity arm span during one year of treatment was excellent (r = 0.65, p < 0.0025). We surmise that body proportions do not deteriorate when growth velocity is stimulated in MMC patients. Both supine length and arm span measurements are necessary to document growth in children with spinal dysraphism.

Recombinant human growth hormone in short children born small for gestational age. German Study Group.

The effects of recombinant human growth hormone (rhGH) treatment in 69 prepubertal, non-GH deficient children born small for gestational age (SGA) were evaluated over 2 years. At start of the study mean age was 5.1 years, mean bone age was 3.8 years and mean height SDS was -4.0. The children were randomly allocated to 3 groups receiving no treatment or daily subcutaneous injections of rhGH at a dose of 0.1 IU/kg body weight (group 0.1 IU) or 0.2 IU/kg body weight (group 0.2 IU). At start of the study mean height velocity SDS was -1.4 in the control group, -0.7 in group 0.1 IU and -1.4 in group 0.2 IU. After 2 years there was a significant increase in height velocity SDS in children treated with rhGH as compared to untreated children. Mean height velocity SDS after the first year of treatment was -1.2 in the control group, 2.8 in group 0.1 IU and 5.5 in group 0.2 IU. Corresponding values during the second year were -0.9, 1.6 and 2.9. A statistically significant difference was observed between the groups receiving 0.1 IU/kg/day and 0.2 IU/kg/day during the first year of treatment, whereas no difference between the treatment groups was found during the second year. Catch-up growth, i.e. a height velocity 1 SD above the mean, was achieved for 86% of group 0.1 IU and 95% of group 0.2 IU during the first year of treatment and was maintained for 65% and 79% of the patients in group 0.1 IU and 0.2 IU respectively in the second year. GH treatment was associated with a distinct acceleration of bone age. Tolerance of treatment was good. No clear trends were seen in any of the laboratory variables. In conclusion, this study shows that daily rhGH given at a dose of 0.1-0.2 IU/kg/day for 24 months is an effective and safe therapy to increase linear growth and induce catch-up growth in short SGA children.
