- <i>Background/Aims:</i> Fetal growth restriction is a complex problem of pregnancy arising from multiple etiologies. Key regulatory elements of growth are the insulin-like growth factor (IGF) axis, and estrogen and progesterone receptors. The aims were to determine the relations of expression of IGF-I, estrogen receptors α and β (ERα and ERβ, respectively), and progesterone receptor (PR), with maternal anthropometry, focusing on birth weight outcomes. <i>Methods:</i> Placental samples were obtained from 33 patients following delivery. mRNA expression was determined by a solution hybridization technique. Samples were divided into normal control (NC) and growth-restricted (GR) groups. <i>Results:</i> IGF-I expression was lower in the GR as compared to the NC group. PR levels correlated positively with IGF-I expression, infant anthropometry, and gestational age (GR). ERα correlated positively with PR expression (NC), and maternal BMI at delivery (GR). ERβ correlated positively with maternal delivery weight and gestational age (NC). <i>Conclusion:</i> The differences in placental expression of IGF-I emphasize its key role in birth weight outcomes. We further suggest the importance of PR expression in the pathogenesis of intrauterine growth restriction, as there were direct correlations of PR expression with both IGF-I expression and infant anthropometric parameters, as well as gestational age.

- Background: Achondroplasia is a skeletal dysplasia with extreme, disproportionate, short stature. Aim: In a 5-y growth hormone (GH) treatment study including 1 y without treatment, we investigated growth and body proportion response in 35 children with achondroplasia. Methods: Patients were randomized to either 0.1 IU/kg (n=18) or 0.2 IU/kg (n=17) per day. GH treatment was interrupted for 12 mo after 2 y of treatment in prepubertal patients to study catch-down growth. Mean height SDS (HSDS) at start was -5.6 and -5.2 for the low- and high-dose groups, respectively, and mean age 7.3 and 6.6 y. Results: Mean growth velocity (baseline 4.5/4.6 cm/y for the groups) increased significantly by 1.9/3.6 cm/y during the first year and by 0.5/1.5 cm/y during the second year. During the third year, a decrease of growth velocity was observed at 1.9/1.3 cm/y below baseline values. HSDS increased significantly by 0.6/0.8 during the first year of treatment and in total by 1.3/1.6 during the 5 y of study. Sitting height SDS improved significantly from -2.1/-1.7 to -0.8/0.2 during the study. Body proportion (sitting height/total height) or arm span did not show any significant change. Conclusion: GH treatment of children with achondroplasia improves height during 4 y of therapy without adverse effect on trunk-leg disproportion. The short-term effect is comparable to that reported in Turner and Noonan syndrome and in idiopathic short stature.

- ObjectiveTo characterise early growth and neurocognitive development in children of mothers with a history of eating disorders (ED). PopulationChildren born to mothers with previous ED (n=47) (24 anorexia nervosa, 20 bulimia nervosa, 3 unspecified ED), and controls (n=65). MethodsMean values and standard deviation scores of weight and height from birth to 5years of age and head circumference up to 18months of age were compared between groups. Neurocognitive development was studied at the age of 5years by the validated parent questionnaire Five to Fifteen. ResultsWe previously reported that mothers with a history of ED conceived infants with lower birthweight and head circumference than controls. At 3months of age, body mass index (BMI) was no longer reduced but mean head circumferences of the children born to mothers with ED were smaller throughout the observation period. Similarly, the longitudinal results of the standard deviation scores of head circumference showed a significant overall group effect with lower levels in both subgroups of ED (anorexia nervosa and bulimia nervosa). The children of the ED mothers also had significantly higher Five to Fifteen scores than controls, reflecting difficulties in language skills. Head circumference at birth correlated with language skills in the children of mothers with ED. ConclusionChildren of mothers with previous ED demonstrated an early catch-up in BMI, but the average head circumference continued to be delayed until at least 18months of age. The reduced head growth was related to delayed neurocognitive development.
