Aim  The aim of this study was to determine the effects of early childhood stunting (height for age 2SD or more below reference values) and interventions on fine motor abilities at 11 to 12 years, and the relationship between fine motor abilities and school achievement and intelligence. Method  A cohort of stunted children who had participated in a randomized trial of psychosocial stimulation and/or nutritional supplementation in early childhood was compared with a group of non‐stunted children. Fine motor abilities were assessed in 116 stunted (67 males, 49 females) and 80 non‐stunted children (43 males, 37 females) at a mean age of 11 years 8 months (SD 4.3mo) and 11 years 9 months (SD 3.8mo) respectively. Testers were blind to the children’s group assignment. Results  Two fine motor factors were derived: rapid sequential continuous movements (RSCM) and dexterity. No effect of the early intervention was found. RSCM scores were lower in the stunted group than in the non‐stunted group (p=0.01), but differences in dexterity were not significant (p=0.18) after adjusting for social background. Among stunted children, the RSCM score was significantly associated with IQ (p=0.04) and school achievement (all p<0.05). Interpretation  Stunting in early childhood is associated with poor scores on tests of rapid sequential continuous hand movements in later childhood. Children with poorer scores are at greater risk for low IQs and low levels of school achievement.

Abstract Context Somapacitan is a long-acting GH derivative for treatment of GH deficiency (GHD). Objective Evaluate the efficacy and tolerability of somapacitan in children with GHD after 2 years of treatment and after the switch from daily GH. Design A randomized, multinational, open-labelled, controlled parallel group phase 3 trial, comprising a 52-week main phase and 3-year safety extension (NCT03811535). Setting Eighty-five sites across 20 countries. Patients A total of 200 treatment-naïve prepubertal patients were randomized and exposed; 194 completed the 2-year period. Interventions Patients were randomized 2:1 to somapacitan (0.16 mg/kg/wk) or daily GH (0.034 mg/kg/d) during the first year, after which all patients received somapacitan 0.16 mg/kg/wk. Main outcome measures Height velocity (HV; cm/year) at week 104. Additional assessments included HV SD score (SDS), height SDS, IGF-I SDS, and observer-reported outcomes. Results HV was sustained in both groups between 52 and 104 weeks. At week 104, mean (SD) for HV between weeks 52 and 104 was 8.4 (1.5) cm/year after continuous somapacitan treatment and 8.7 (1.8) cm/year after 1 year of somapacitan treatment following switch from daily GH. Secondary height-related endpoints also supported sustained growth. Mean IGF-I SDS during year 2 was similar between groups and within normal range (−2 to +2). Somapacitan was well tolerated, with no safety or tolerability issues identified. GH patient preference questionnaire results show that most patients and their caregivers (90%) who switched treatment at year 2 preferred once-weekly somapacitan over daily GH treatment. Conclusions Somapacitan in children with GHD showed sustained efficacy and tolerability for 2 years, and after switching from daily GH. Patients/caregivers switching from daily GH expressed a preference for somapacitan. Clinical Trial Registration NCT03811535

Powders containing iron and other micronutrients are recommended as a strategy to prevent nutritional anaemia and other micronutrient deficiencies in children. We assessed the effects of provision of two micronutrient powder formulations, with or without zinc, to children in Pakistan. We did a cluster randomised trial in urban and rural sites in Sindh, Pakistan. A baseline survey identified 256 clusters, which were randomly assigned (within urban and rural strata, by computer-generated random numbers) to one of three groups: non-supplemented control (group A), micronutrient powder without zinc (group B), or micronutrient powder with 10 mg zinc (group C). Children in the clusters aged 6 months were eligible for inclusion in the study. Powders were to be given daily between 6 and 18 months of age; follow-up was to age 2 years. Micronutrient powder sachets for groups B and C were identical except for colour; investigators and field and supervisory staff were masked to composition of the micronutrient powders until trial completion. Parents knew whether their child was receiving supplementation, but did not know whether the powder contained zinc. Primary outcomes were growth, episodes of diarrhoea, acute lower respiratory tract infection, fever, and incidence of admission to hospital. This trial is registered with ClinicalTrials.gov, number NCT00705445. The trial was done between Nov 1, 2008, and Dec 31, 2011. 947 children were enrolled in group A clusters, 910 in group B clusters, and 889 in group C clusters. Micronutrient powder administration was associated with lower risk of iron-deficiency anaemia at 18 months compared with the control group (odds ratio [OR] for micronutrient powder without zinc=0·20, 95% CI 0·11–0·36; OR for micronutrient powder with zinc=0·25, 95% CI 0·14–0·44). Compared with the control group, children in the group receiving micronutrient powder without zinc gained an extra 0·31 cm (95% CI 0·03–0·59) between 6 and 18 months of age and children receiving micronutrient powder with zinc an extra 0·56 cm (0·29–0·84). We recorded strong evidence of an increased proportion of days with diarrhoea (p=0·001) and increased incidence of bloody diarrhoea (p=0·003) between 6 and 18 months in the two micronutrient powder groups, and reported chest indrawing (p=0·03). Incidence of febrile episodes or admission to hospital for diarrhoea, respiratory problems, or febrile episodes did not differ between the three groups. Use of micronutrient powders reduces iron-deficiency anaemia in young children. However, the excess burden of diarrhoea and respiratory morbidities associated with micronutrient powder use and the very small effect on growth recorded suggest that a careful assessment of risks and benefits must be done in populations with malnourished children and high diarrhoea burdens.

Abstract Context Somapacitan, a once-weekly reversible albumin-binding growth hormone (GH) derivative, is evaluated in short children born small for gestational age (SGA). Objective Evaluate efficacy, safety, tolerability as well as total and bioactive insulin-like growth factor I (IGF-I) response of once-weekly somapacitan compared to daily GH in children born SGA. Methods REAL5 is a randomized, multicenter, open-label, controlled phase 2 study comprising a 26-week main phase, a 26-week extension, and an ongoing 4-year safety extension (NCT03878446), conducted at 38 sites across 12 countries. A total of 62 GH-treatment-naïve, prepubertal short children born SGA were randomized; 61 completed 52-weeks of treatment. Patients were randomized (1:1:1:1:1) to somapacitan (0.16, 0.20, or 0.24 mg/kg/week) or daily GH (0.035 or 0.067 mg/kg/day), all administered subcutaneously. Results Estimated mean height velocity (HV; cm/year) at week 52 was 8.5, 10.4, and 10.7 cm/year for somapacitan 0.16, 0.20, and 0.24 mg/kg/week, respectively, and 9.3 and 11.2 cm/year for daily GH 0.035 and 0.067 mg/kg/day, respectively. Dose-dependent increases in total IGF-I, as well as peak IGF-I bioactivity, were observed for both treatments and were similar between comparator groups. For somapacitan, exposure-response modeling indicated highest efficacy with 0.24 mg/kg/week after 52 weeks of treatment. Similar safety and tolerability were demonstrated across all groups. Conclusion A sustained dose-dependent growth response was demonstrated for somapacitan after 52 weeks of treatment. Overall, somapacitan 0.24 mg/kg/week provides similar efficacy, safety, and tolerability, as well as comparable bioactive and total IGF-I response, as daily GH (0.067 mg/kg/day) in children born SGA.

Poor growth and micronutrient deficiency mainly attack older infants and young children. Some countries have adopted clinically effective measures to combat malnutrition, but the compliance and improvement in efficacy of intervention vehicles in national programs require evaluation. Baseline and follow-up cross-sectional surveys were conducted before and after a nutrition intervention program in 3 national poverty counties in China. Soybean-based complementary food supplements called Yingyangbao (YYB) in Chinese and training materials on child feeding were distributed to households with children aged 6-23 months for 18 months. Representative children were selected by probability proportional to size sampling methods to assess compliance of YYB and the intervention efficacy. A questionnaire was designed to collect data on basic characteristics of children, breastfeeding, 24-hour dietary intake, and consumption and appetite of YYB. Anthropometrics and hemoglobin were measured in the field, and anemia prevalence was evaluated. Venous blood was drawn from children aged 12-35 months to evaluate micronutrient status. Logistic regression was used to identify the risk factors for children's anemia. Of the children involved in the follow-up survey (n = 693), the P50 (P25, P75) intake of YYB was 6.7 (3.5, 7.0) sachets weekly, and 54.7% of the children liked the taste of YYB. Compared with the baseline situation (n = 823), the proportion of children fed a diverse diet and foods rich in iron or vitamin A increased (P < 0.01) in the follow-up study. The prevalence of stunting and underweight decreased (P < 0.05), the prevalence of anemia decreased from 28.0% to 19.9% (P < 0.01), and the prevalence of vitamin B12 deficiency decreased from 26.8% to 15.4% (P < 0.01). For children aged 12-23 months, those who liked YYB and consumed 6 or more sachets of YYB weekly were at lower risk for anemia (OR = 0.34, 95% CI 0.13-0.90, P < 0.05), but the risk of stunting was associated with a non-diverse diet (OR = 1.48, 95% CI 1.06-2.07, P < 0.05). The quality of diet and nutritional status of children aged 6-23 months are significantly improved by the intervention of YYB and nutrition education, and good compliance to YYB contributes to a low risk for anemia.

This trial randomly assigned girls 5 to 12.5 years of age with Turner's syndrome to receive growth hormone, low-dose estrogen, neither, or both. Growth hormone increased adult height. Combining ultra-low-dose estrogen with growth hormone during childhood may optimize growth. Turner's syndrome, which results from partial or complete X-chromosome monosomy, occurs in about 1 in 2000 live female births 1 and encompasses diverse clinical features, including short stature, ovarian dysgenesis, and neurocognitive problems. 2 The marked short stature in Turner's syndrome (an average, untreated adult height 20 cm below that of the general female population 3 , 4 ) can be ameliorated by treatment with recombinant human growth hormone. Although there is substantial evidence that growth hormone treatment increases adult stature in patients with Turner's syndrome, 5 – 13 data from randomized, double-blind, placebo-controlled studies have been lacking. 13 Ovarian failure, the second major problem associated with . . .

Abstract Context Pegpesen is a novel Y-shape pegylated recombinant human growth hormone (rhGH) for once-weekly treatment of children with growth hormone deficiency (GHD). Objective This work aimed to evaluate the efficacy and safety of Pegpesen in children with GHD vs daily rhGH. Methods A multicenter, randomized, controlled phase 3 clinical trial was conducted at 23 centers in China with a duration of 52 weeks’ treatment. There were 391 pediatric participants diagnosed with GHD. Participants were randomly assigned 2:1 to a weekly Pegpesen group (140 μg/kg/week) or a daily rhGH group (245 μg/kg/week) for 52 weeks. The primary end point was the growth velocity (GV) at 52 weeks, and the secondary end points mainly involved changes from baseline in height SD scores for chronological age and bone age (ΔHt SDS CA and ΔHt SDS BA). Results At 52 weeks, the least squares mean (LS means) of GV was 9.910 cm/year in the Pegpesen group and 10.037 cm/year in the daily rhGH group. The LS means difference between groups was −0.127 (95% CI, −0.4868 to 0.2332), confirming that weekly Pegpesen is noninferior to daily rhGH. The LS means of ΔHt SDS CA, ΔHt SDS BA, were similar across both groups (all P > .05). Safety profiles and adherence were comparable. Conclusion Pegpesen was noninferior to daily rhGH, with similar safety, lower dosage requirements, thus presenting a new therapeutic option for children with GHD.

Small-quantity lipid-based nutrient supplements (SQ-LNS) are promising home fortification products, but the optimal zinc level needed to improve growth and reduce morbidity is uncertain. We aimed to assess the impact of providing SQ-LNS with varied amounts of zinc, along with illness treatment, on zinc-related outcomes compared with standard care. In a placebo-controlled, cluster-randomized trial, 34 communities were stratified to intervention (IC) or non-intervention cohorts (NIC). 2435 eligible IC children were randomly assigned to one of four groups:1) SQ-LNS without zinc, placebo tablet; 2) SQ-LNS containing 5mg zinc, placebo tablet; 3) SQ-LNS containing 10mg zinc, placebo tablet; or 4) SQ-LNS without zinc and 5mg zinc tablet from 9–18 months of age. During weekly morbidity surveillance, oral rehydration salts were provided for reported diarrhea and antimalarial therapy for confirmed malaria. Children in NIC (n = 785) did not receive SQ-LNS, tablets, illness surveillance or treatment. At 9 and 18 months, length, weight and hemoglobin were measured in all children. Reported adherence was 97 ± 6% for SQ-LNS and tablets. Mean baseline hemoglobin was 89 ± 15g/L. At 18 months, change in hemoglobin was greater in IC than NIC (+8 vs -1g/L, p<0.0001), but 79.1% of IC were still anemic (vs. 91.1% in NIC). Final plasma zinc concentration did not differ by group. During the 9-month observation period, the incidence of diarrhea was 1.10 ± 1.03 and of malaria 0.54 ± 0.50 episodes per 100 child-days, and did not differ by group. Length at 18 months was significantly greater in IC compared to NIC (77.7 ± 3.0 vs. 76.9 ± 3.4 cm; p<0.001) and stunting prevalence was significantly lower in IC (29.3%) than NIC (39.3%; p<0.0001), but did not differ by intervention group within IC. Wasting prevalence was also significantly lower in IC (8.7%) than in NIC (13.5%; p = 0.0003). Providing SQ-LNS daily with or without zinc, along with malaria and diarrhea treatment, significantly increased growth and reduced stunting, wasting and anemia prevalence in young children.

Abstract Context Management of GH-treated children with idiopathic short stature (ISS) with early puberty and adolescents in midpuberty at initiation of treatment is challenging. Objective To assess the effect of combined GH/GnRHa therapy during puberty on achieved adult height (AHt) in these children with ISS and to determine whether outcome depended on sex and pubertal status at initiation of GH therapy. Design Retrospective, single-center observational study from 2003-2018. Setting Tertiary endocrine center. Patients One hundred ninety-two GH-treated children with ISS; 58 of 192 were treated by GH/GnRHa during puberty; 31 of 58 were prepubertal (19 girls) and 27 of 58 pubertal (19 girls) at initiation of GH. Main Outcome Measures AHt, gain-in-height standard deviation score (SDS), AHt vs predicted adult height (PAHt), AHt vs target height (THt). Results Most boys and girls attained AHt SDS within the normal range (−0.73 ± 0.60 and −0.85 ± 0.65, respectively). Treatment modality, pubertal status, and sex were tested for their joint effect on growth outcome measures. Combined GH/GnRHa therapy increased AHt vs PAHt (P < 0.001) and AHt vs THt (P = 0.035). Prepubertal status at onset of GH treatment increased AHt (P = 0.049), gain-in-height SDS (P < 0.001), AHt vs PAHt (P < 0.001), and AHt vs THt (P = 0.042). Female sex increased AHt vs PAHt (P < 0.001). Conclusions Our study demonstrated a beneficial effect of combined GH/GnRHa therapy in increasing AHt outcome in children with ISS with early/normal puberty and in adolescents naïve to GH treatment who are in midpuberty at initiation of therapy. This effect was more pronounced in the prepubertal group and in girls. Prospective randomized controlled trials are needed to assess whether GnRHa can increase AHt in GH-treated children with ISS. Combined GH/GnRHa therapy is beneficial in increasing AHt outcome in children with ISS with early/normal puberty and in adolescents naïve to GH treatment who are in midpuberty at start of therapy.

Abstract Background Some children born small for gestational age (SGA) experience supra-physiological insulin-like growth factor-I (IGF-I) concentrations during GH treatment. However, measurements of total IGF-I concentrations may not reflect the bioactive fraction of IGF-I which reaches the IGF-I receptor at target organs. We examined endogenous IGF-bioactivity using an IGF-I kinase receptor activation (KIRA) assay that measures the ability of IGF-I to activate the IGF-IR in vitro. Aim To compare responses of bioactive IGF and total IGF-I concentrations in short GH treated SGA children in the North European Small for Gestational Age Study (NESGAS). Material and method In NESGAS, short SGA children (n = 101, 61 males) received GH at 67 µg/kg/day for 1 year. IGF-I concentrations were measured by Immulite immunoassay and bioactive IGF by in-house KIRA assay. Results Bioactive IGF increased with age in healthy pre-pubertal children (n = 94). SGA children had low-normal bioactive IGF levels at baseline (-0.12 (1.8 SD), increasing significantly after one year of high-dose GH treatment to 1.1 (1.4) SD, P < 0.01. Following high-dose GH, 68% (n = 65) of SGA children had a total IGF-I concentration >2SD (mean IGF-I 2.8 SDS), whereas only 15% (n = 15) had levels of bioactive IGF slightly above normal reference values. At baseline, bioactive IGF (SDS) was significantly correlated to height (SDS) (r = 0.29, P = 0.005), in contrast to IGF-I (SDS) (r = 0.17, P = 0.10). IGF-I (SDS) was inversely correlated to delta height (SDS) after one year of high-dose GH treatment (r = -0.22, P = 0.02). Conclusion In contrast to total IGF-I concentrations, bioactive IGF stayed within the normal reference ranges for most SGA children during the first year of GH treatment.
