NETs, which can secrete hormones including insulin, gastrin, and glucagon, among others, are common in patients with MEN1 and are a major cause of morbidity and premature death.

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.

One of the most common monogenic causes of obesity is heterozygous mutations in the Melanocortin 4 receptor (MC4R), which are found in 5.7% to 8.6% of individuals with early-onset obesity. We report, the effect of Semaglutide, a long-acting Glucagon like peptide (GLP1) analogue, in the treatment of severe obesity in an adolescent boy with a heterozygous mutation in MC4R.\u0000Case presentation: A 13-year-old boy with a history of excessive weight gain since infancy was referred to the specialised weight management team. He was born at full-term with a birth weight of 3.57kg (50th centile), but his weight consistently exceeded the 99.6th percentile after the age of one year. At the age of five years, he was diagnosed with autism spectrum disorder (ASD). Diagnostic investigations revealed insulin resistance, and dyslipidaemia, while genetic testing confirmed a heterozygous mutation in MC4R (E61K), inherited from his mother. Managing his condition was challenging due to his rapid weight gain, needle phobia, and behavioural difficulties.\u0000 Despite intense multidisciplinary lifestyle interventions, he continued to gain weight, reaching a peak weight of 187.5kg [+16.65 standard deviation score (SDS)], body mass index (BMI) of 56.9kg/m2 (+4.19 SDS), body fat 63.9%] at the age of 13 years. Due to severe ASD and needle phobia, he was not keen on daily GLP-1 injections. He was commenced on Semaglutide subcutaneous injection at a dose of 0.25mg weekly, gradually increasing to the maximum dose of 1mg weekly. Over the course of 12 weeks, his BMI decreased to 52.2kg/m2 (+4.08SDS) and weight dropped to 176.8kg (+14.76SDS, body fat: 52.7%). At the 3-month and 12-month reviews post treatment, he achieved weight loss of 5.7% and 11% respectively.

A recent case series underscored the benefits of therapy with Liraglutide, a short-acting GLP-1 analogue, in rare genetic cases of early-onset obesity.
