This study was undertaken to investigate the prevalence of coeliac disease in children and adolescents with Turner syndrome. Eighty-seven children and adolescents with Turner syndrome were screened for IgA-antiendomysium antibodies (EMA) and IgA-antigliadin antibodies (AGA), 5% (4/87) being found to be EMA-positive, and 15% (13/87) to have AGA levels above normal. Of the 10 patients who were either AGA- or EMA-positive and further investigated with intestinal biopsy, four manifested villous atrophy (i.e. all three of the EMA-positive patients, but only one of the seven AGA-positive patients). The results suggest EMA-positivity to be a good immunological marker for use in screening for coeliac disease, and such screening to be justified in patients with Turner syndrome.

This paper reports results from an ongoing, randomized, multicentre national trial. The aim is to elucidate whether a dose of growth hormone (GH) of 0.2 IU/kg (0.07 mg/kg), given either as once-daily or twice-daily injections during puberty, is more effective than a once-daily dose of 0.1 IU/kg/day (0.03 mg/kg/day) in improving final height in children with GH deficiency (GHD). The twice-daily regimen comes closer to the spontaneous GH secretion pattern in puberty. Ninety-two children with GHD who had been receiving GH therapy for at least 1 year, and with spontaneous puberty or who were prepubertal and due to be started on replacement therapy to induce puberty, were randomly assigned to receive GH as follows: group A, 0.1 IU/kg/day (0.03 mg/kg/day), administered once daily; group B, 0.2 IU/kg/day (0.07 mg/kg/day), administered once daily; and group C, 0.2 IU/kg/day (0.07 mg/kg/day), divided into two equal injections given at 12-hour intervals. Pubertal height gain was 0.7, 0.7 and 1.3 SDS for groups A, B and C, respectively. The gain in height during puberty was thus most marked in group C. Mean final height, when corrected for parental height, was between 0 and 1 SDS in all treatment groups. All but seven children reached a final height within +/- 2 SD of the general population. There was a wide range of final heights in all three treatment groups. This variation in response suggests the need to individualize treatment in order to achieve an appropriate final height for most individuals.

The aims of this study were to evaluate the efficacy and safety of different doses of growth hormone (GH) treatment in prepubertal short children born small-for-gestational-age (SGA). Forty-eight children born SGA from Sweden, Finland, Denmark and Norway were randomly allocated to three groups: a control group of 12 children received no treatment for 2 y, one group was treated with GH at 0.1 IU/kg/d (n=16), and one group was treated with GH at 0.2 IU/kg/d (n=20). In total 42 children completed 2 y of follow-up, and 24 children from the treated groups completed 3 y of treatment. Their mean (SD) age at the start of the study was 4.69 (1.61) y and their mean (SD) height was -3.16 (0.70) standard deviation scores (SDS). The children remained prepubertal during the course of the study. No catch-up growth was observed in the untreated group, but a clear dose-dependent growth response was found in the treated children. After the third year of treatment, the group receiving the higher dose of GH, achieved their target height. The major determinants of the growth response were the dose of GH used, the age at the start of treatment (the younger the child, the better the growth response) and the family-corrected individual height deficit (the higher the deficit, the better the growth response). Concentration of insulin-like growth factor-I (IGF-I) and IGF-binding protein-3 increased during treatment. An increase in insulin levels was found without negative effects on fasting glucose levels or glycosylated haemoglobin levels. GH treatment was well tolerated. In conclusion, short prepubertal children born SGA show a dose-dependent growth response to GH therapy, and their target height SDS can be achieved within 3 y of treatment given GH at 0.2 IU/kg/d. However, the long-term benefit of different regimens of GH treatment in children born SGA remains to be established.
