11.8 Early-onset obesity: unrecognized first evidence for GNAS mutations and methylation changes

A Grüters-Kieslich , M Reyes , A Sharma , C Demirci , TJ DeClue , E Lankes , D Tiosano , D Schnabel , H Jüppner

To read the full abstract: J Clin Endocrinol Metab 2017; 102 (8): 2670-2677These case reports lead to an important conclusion which changes our diagnostic work-up of early-onset childhood obesity. The authors shows that thorough work-up of clinical cohorts, combined with genetic and epigenetic analyses, can define new characteristic features of known disorders. PHP1A, and surprisingly also PHP1B,...

1.6. Effect of initial levothyroxine dose on neurodevelopmental and growth outcomes in children with congenital hypothyroidism

Brief summary: Current guidelines for congenital hypothyroidism recommend a starting dose of 10–15 μg/d of levothyroxine for optimal treatment (1). Over the last years, some studies suggested that overtreatment of patients during infancy by high levothyroxine doses might have negative effects on neurocognitive and behavioral development (2). The presented multicenter prospective randomized trial aimed at comparing the effect of higher (12.5–15.0 μg/d levoth...

Brief summary: This phase 3 double-blind, parallel-group, randomized, placebo-controlled trial over 68 weeks randomised (2:1) 201 adolescents with obesity to receive semaglutide 2.4 mg once weekly or placebo. Both groups also received lifestyle intervention. The primary endpoint was the percentage change in BMI. Treatment with semaglutide produced clinically relevant reductions in BMI and body weight, and improvements in cardiovascular risk factors, which were all significantl...

PMID: 33404684.The derivation of iPSCs and their subsequent conversion to islet like clusters from a patient with diffuse CHI due to a homozygous mutation in the ABCC8 provided these authors a unique opportunity to study the molecular basis of CHI and to develop potential novel treatment options by screening...

R West , J Hong , JGB Derraik , D Webster , NL Heather , PL Hofman

J Clin Endocrinol Metab. 2020;105:dgaa415. doi: 10.1210/clinem/dgaa415.The optimal cut-off for neonatal screening has long been a matter of debate. The optimal balance between optimal detection of cases and increase of false positive patients is difficult to define. Also, in the most recent guidelines for congenital hypothyroidism (see previous paper in this chapter 3.7), no precise cut-off...
