    Abstract Introduction: A substantial proportion of SGA patients present with a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic and non-syndromic patients impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of a SGA cohort and analyze rhGH response based on adult height (AH).
    Methods: Clinical and auxological data of SGA patients treated with rhGH, who had reached AH, were retrieved from BELGROW, a national database of all rhGH treated patients held by BESPEED (BElgian Society for PEdiatric Endocrinology and Diabetology). SGA patients were categorized in syndromic or non-syndromic patients.
    Results: 272 patients were included, 42 classified as syndromic (most frequent diagnosis (n=6): fetal alcohol syndrome and Silver-Russell syndrome). Compared with non-syndromic patients, syndromic were younger [years (median (P10/P90)] 7.43 (4.3/12.37) vs 10.21 (5.43/14.03), p=0.0005), shorter (height SDS -3.39 (-5.6/-2.62) vs -3.07 (-3.74/-2.62), p=0.0253) and thinner (BMI -1.70 (-3.67/0.04) vs -1.14 (-2.47/0.27) SDS, p=0.0054) at start of rhGH treatment. First year rhGH response was comparable (delta height SDS +0.54 (0.24/0.94) vs +0.56 (0.26/0.92), p=0.94). Growth pattern differed with syndromic patients having a higher prepubertal (SDS +1.26 vs +0.83, p=0.0048), but a lower pubertal height gain compared to the non-syndromic group (SDS -0.28 vs 0.44, p=0.0001). Mean rhGH dose was higher in syndromic SGA patients (mg/kg body weight/day 0.047 (0.039/0.064) vs 0.043 (0.035/0.056), p=0.0042). AH SDS was lower in syndromic SGA patients (-2.59 (-4.99/-1.57) vs -2.32 (-3.3/-1.2), p=0.0107). The majority in both groups remained short (<-2 SDS: syndromic 71%, non-syndromic 63%). Total height gain was comparable in both groups (delta height SDS +0.76 (-0.70/1.48) vs +0.86 (-0.12/1.86), p=0.41).
    Conclusions: Compared to non-syndromic SGA patients, syndromic SGA patients were shorter when starting rhGH therapy, started rhGH therapy earlier, and received a higher dose of rhGH. At AH, syndromic SGA patients were shorter than non-syndromic ones, but their height gain under rhGH therapy was comparable.

    Abstract Introduction A variable near adult height (NAH) outcome after growth hormone (GH) therapy in Noonan syndrome (NS) patients with short stature has been reported. The main objective of this study was to evaluate NAH and body mass index (BMI) evolution in a large Belgian cohort of NS patients treated for short stature. The secondary objectives were to investigate whether sex, genotype, the presence of a thoracic deformity and/or a heart anomaly might affect NAH and to validate the recently developed NAH prediction model by Ranke et al. Methods Clinical and auxological data of GH treated short NS patients born before 2001 were extracted from the national Belgrow registry. NAH was available in 54 (35 male) genotyped NS using a gene panel of 9 genes, showing pathogenic variants in PTPN11 in 32 and in SOS1 in 5 patients, while in 17 patients gene panel analysis was inconclusive (no mutation group). Results After a median (P10; P90) duration of 5.4 (2.2-10.3) years of GH therapy with a median dose of 0.05 mg/kg/day NS patients reached a median NAH of -1.7 (-3.4; -0.8) SDS. Median total height gain was 1.1 (0.1; 2.3) SDS. Sex, genotype and the presence of a thoracic or cardiac malformation did not correlate with NAH or total height gain. Linear regression modelling revealed that height SDS at start (beta=0.90, p<0.001), mid-parental height SDS (beta =0.27; p=0.005), birth weight SDS (beta=0.15; p=0.051), age at start (beta=0.07; p=0032) were independently associated with NAH SDS. Median BMI SDS increased significantly (p<0.001) from -1.0 (-2.5; 0.0) at start to -0.2 (-1.5; 0.9) at NAH. The observed NAH in a subgroup of 44 patients with more than 3 years of GH treatment was not statistically different from the predicted NAH by the Noonan NAH prediction model of Ranke. Conclusion Long-term GH therapy at a dose of 0.05 mg/kg/day in short NS patients is effective in improving adult height and BMI, irrespective of the genotype and presence or absence of cardiac and or thoracic anomalies.

    Abstract Background: Involving pediatric nephrological input in the clinical diagnostic work-up of children with short stature, gave rise to the hypothesis that the presence of an underlying renal tubular disorder in children with short stature is possibly underestimated. This study focussed on the added value of calculated urinary fractional excretion (FE) in the early detection of tubular disorders in children with growth failure.
    Methods: This trial was designed as an observational study analyzing the medical files of children between 5 and 16 years who had been referred for short stature to the pediatric endocrinology outpatient clinic at the University Hospital Antwerp between 25/01/2015 and 01/03/2019. Based on the laboratory results of the simultaneously taken blood and urine sample, the fractional excretions of Sodium, Chloride, Potassium, Calcium, Phosphate, and Magnesium were calculated.
    Results: Of the 299 patients, 54 patients had at least one deviating fractional excretion value, requiring further investigation (control sample of blood and urine, kidney ultrasound or 24 h urine collection). Genetic screening for tubulopathies was performed in 19 patients. In 5 patients (1.7% of the total population) a tubulopathy was confirmed based on genetic analysis.
    Conclusion: This study explored the possibility of using fractional excretions as a screening test to obtain an earlier diagnosis of tubular disorders in children with short stature. Of the 299 patients, 5 patients were diagnosed with a genetically confirmed tubulopathy. Based on these results, we propose a flowchart for an additional work-up in all children with a deviating fractional excretion.

    Abstract An increased blood pressure is a known comorbidity of both type 1 diabetes (T1DM) and obesity in children. Increasing evidence suggests a subtle interplay between epidermal growth factor (EGF) and renin along the juxtaglomerular system, regulating the impact of blood pressure on kidney health and the cardiovascular system. In this study, we investigated the relation between urinary EGF, serum renin and blood pressure in children with obesity or T1DM. 147 non-obese children with T1DM and 126 children with obesity, were included. Blood pressure was measured and mean arterial pressure (MAP) and the pulse pressure (PP) were calculated. Serum renin and urinary EGF levels were determined with a commercial ELISA kit. Partial Spearman rank correlation coefficients and multiple linear regression models were used to study the association between renin, the urinary EGF/urinary creatinine ratio and blood pressure parameters. The urinary EGF/urinary creatinine ratio is correlated with the SBP and the MAP in boys with obesity as well as in boys with T1DM. Multiple regression analysis showed that sex and pulse pressure in male subjects were found to be independently associated with renin. Sex, the presence of diabetes, age, the glomerular filtration rate and both pulse pressure and mean arterial pressure in male subjects were independently associated with urinary EGF/urinary creatinine. In conclusion, in boys with either obesity or diabetes, pulse pressure and mean arterial pressure are negatively associated with the functional integrity of the nephron, which is reflected by a decreased expression of urinary EGF.

    Abstract Aims: Micro-albuminuria is considered an early clinical sign of diabetes nephropathy, however, early decrease of glomerular filtration can be present years before the presence of microalbuminuria. In this study, we explored whether urinary epidermal growth factor (uEGF) might serve as an early marker of diabetes nephropathy compared to microalbuminuria in children and adolescents.
    Methods: Children with type 1 diabetes mellitus (n = 158) and healthy controls (n = 40) were included in this study. Serum and urine samples were collected three times with an interval of at least one month to determine creatinine (serum and urine), epidermal growth factor and albumin (urine). Demographic data and routine lab values were extracted out of the electronic patient files.
    Results: uEGF was significantly lower in children with T1DM compared to healthy controls (p = 0.032). A relatively lower glomerular filtration rate (eGFR) was associated with a decreased uEGF (p < 0.001). uEGF was independently associated with eGFR in a multivariate analysis.
    Conclusion: This study provides evidence that uEGF can serve as an early marker of diabetes nephropathy in children and adolescents.

    Abstract Objectives: To improve adult height in pubertal girls with a poor height prediction, treatment with growth hormone (GH) can be used in combination with a gonadotropin releasing hormone agonist (GnRHa), to delay closure of the growth plates. However, there are few studies to support this practice, and they show conflicting results. The objective of this trial is to assess the safety and efficacy of this combination treatment in early pubertal girls with a short predicted height, in comparison with matched controls.
    Design patients and methods: We designed an open-label, multicenter, interventional case-control study. Early pubertal girls with predicted adult height (PAH) below -2.5 SDS, were recruited in tertiary care centers in Belgium. They were treated for four years with GH and GnRHa. The girls were followed until adult height (AH) was reached. AH
    Results: Sixteen girls with mean age ( ± SD) at start of 11.0 years (± 1.3) completed the study protocol and follow-up. Their mean height ( ± SD) increased from 131.3 ± 4.1 cm (-2.3 ± 0.7 SDS) at start of treatment to 159.8 ± 4.7 cm (-1.1 ± 0.7 SDS) at AH. In matched controls, height increased from 132.3 ± 4.2 cm (-2.4 ± 0.5 SDS) to 153.2 ± 3.4 cm (-2.1 ± 0.6 SDS) (p<0.001). AH surpassed initial PAH by 12.0 ± 2.6 cm in treated girls; and by 4.2 ± 3.6 cm in the controls (p<0.001). Most treated girls reached normal adult height (>-2SD) (87.5%) and 68.7% reached or superseded the target height (TH), which was the case in only a minority of the controls (37.5% and 6.2%, respectively) (p= 0.003 and 0.001). A serious adverse event possibly related to the treatment, was a fracture of the metatarsals.
    Conclusion: A four-year GH/GnRHa treatment in early pubertal girls with a poor PAH seems safe and results in a clinically relevant and statistically significant increase in AH compared with matched historical controls.

    Abstract Hypomagnesemia in patients with type 1 diabetes (T1D) as well as in obesity has been related to insulin resistance in adults, but not yet in pediatric patients. In this observational single-center study, we aimed to investigate the relation between the magnesium homeostasis, insulin resistance, and body composition in children with T1D and in children with obesity. Children with T1D (n = 148) and children with obesity and proven insulin resistance (n = 121) and healthy controls (n = 36) were included in this study. Serum and urine samples were collected to determine magnesium and creatinine. The total daily dose of insulin (for children with T1D), results from the oral glucose tolerance test (OGTT, for children with obesity), and biometric data were extracted from the electronic patient files. Furthermore, body composition was measured via bioimpedance spectroscopy. Serum magnesium levels were decreased in both children with obesity (0.87 ± 0.07 mmol/l) and children with T1D (0.86 ± 0.07 mmol/l) compared to healthy controls (0.91 ± 0.06; p = 0.005). A lower magnesium level was associated with more severe adiposity in children with obesity, while a worse glycemic control was associated with lower magnesium levels in children with T1D.   Conclusion: Children with T1D and children with obesity have decreased serum magnesium levels. An increased fat mass is associated with lower magnesium levels in childhood obesity, indicating that the adipose tissue is an important factor in magnesium homeostasis. In contrast, glycemic control was the main determining factor for serum magnesium levels in children with T1D. What is Known: • Hypomagnesaemia has been related to insulin resistance in both adults with T1D and adults with obesity. • There is an increasing prevalence of obesity and T1D in childhood, but little is known about the relationship between magnesium and insulin resistance in these children. What is New: • Both children with T1D and children with obesity have decreased serum magnesium levels. • In childhood obesity an increased fat mass is associated with lower magnesium levels, while glycaemic control is the main determining factor for serum magnesium in children with T1D.

    Abstract Objective: Cutaneous adverse events (CAE) from FreeStyle Libre include allergic contact dermatitis (ACD) caused by the allergen isobornyl acrylate (IBOA). We aim to report CAE from this glucose sensor, ACD to IBOA in particular, and the outcome of using barrier films as a prevention.
    Research design and methods: A monocentric, retrospective review of medical files from adult and pediatric patients with diabetes using Freestyle Libre, in the period between December 2016 and April 2019, was performed with a focus on CAE.
    Results: Fifty-seven of 1,036 patients with diabetes (5.5%) were referred to our dermatology department because of CAE from FreeStyle Libre. Thirty-nine of 1,036 (3.8%) had ACD due to IBOA. Only two patients, of whom one sensitized to IBOA, had a benefit from using barrier films.
    Conclusions: CAE occurred in 5.5% of FreeStyle Libre users, and 3.8% suffered from ACD due to IBOA. Barrier films had limited value in the prevention.

    Abstract Purpose: The effects of growth hormone (GH) treatment on linear growth and body composition have been studied extensively. Little is known about the GH effect on energy expenditure (EE). The aim of this study was to investigate the effects of GH treatment on EE in children, and to study whether the changes in EE can predict the height gain after 1 year.
    Methods: Total EE (TEE), basal metabolic rate (BMR), and physical activity level (PAL) measurements before and after 6 weeks of GH treatment were performed in 18 prepubertal children (5 girls, 13 boys) born small for gestational age (n = 14) or with growth hormone deficiency (n = 4) who were eligible for GH treatment. TEE was measured with the doubly labelled water method, BMR was measured with an open-circuit ventilated hood system, PAL was assessed using an accelerometer for movement registration and calculated (PAL = TEE/BMR), activity related EE (AEE) was calculated [AEE = (0.9 × TEE) - BMR]. Height measurements at start and after 1 year of GH treatment were analysed. This is a 1-year longitudinal intervention study, without a control group for comparison.
    Results: BMR and TEE increased significantly (resp. 5% and 7%). Physical activity (counts/day), PAL, and AEE did not change. 11 out of 13 patients (85%) with an increased TEE after 6 weeks of GH treatment had a good first-year growth response (∆height SDS > 0.5).
    Conclusions: GH treatment showed a positive effect on EE in prepubertal children after 6 weeks. No effect on physical activity was observed. The increase in TEE appeared to be valuable for the prediction of good first-year growth responders to GH treatment.
