Albert , Dattani Mehul T. ,

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Deconvolution Analysis: GH secretagogue (LUM-201) enhances growth in individuals with moderate idiopathic Pediatric Growth Hormone Deficiency (iPGHD) by enhancing endogenous GH secretion and increasing IGF-1

Cassorla MD Fernando , Román MD Rossana , Linn Johnson PhD Michael , Avila RN Alejandra , Iñiguez MD German , Baier MD Ingrid , Said RN Daniela , Bruchey PhD Aleksandra , Smith MS Christopher , L. Brinks PhD Erik , C. McKew PhD John , B. Karpf MD David , O. Thorner MD Michael , DSc MBBS

An oral GH secretagogue (GHS), LUM-201, stimulates GHSR-1a receptor to enhance endogenous GH pulsatile release. In moderate iPGHD, pulses of GH are found but at reduced levels, resulting in decreased IGF-1 and poor growth. The impact of LUM-201 on GH profiles during treatment of such children has not been reported.Objective: To characterize GH profiles, defined by deconvolution analysis, based on GH concentration in a time series and its...

Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...

Aim: To uncover a feasible tumor expression prognostic signature and potential therapeutic targets for children with pACT.Methods: Tumor RNAseq from 53 pACT children (70% girls, median age: 1.7yrs) was performed (Illumina). Using a robust, state-of-the-art, differential gene expression analysis pipeline, differentially expressed genes (DEGs: adjusted P<0.05 and |log2 fold-change|>1) were identified (DESeq2...

Background: The majority of children diagnosed with idiopathic isolated growth hormone deficiency (IIGHD) show a normal growth hormone (GH) secretion (assessed by GH stimulation tests) when retested at near adult height (NAH). It appears plausible that if normal stimulated GH secretion is observed in mid-puberty, continuing recombinant human GH (rhGH) treatment may only have a minor effect on NAH. The effect on NAH has never been investigated in a prospective ...

Metabolic risk assessment in children and adolescents using the tri-ponderal mass index

Seo Young-Jun , Suk Shim Young , Sang Lee Hae , Soon Hwang Jin

We assessed the risk of metabolic syndrome in children and adolescents who were classified using the tri-ponderal mass index (TMI) with data from the Korea National Health and Nutrition Examination Survey (KNHANES). Data from 10-18-year-old subjects that were overweight or obese (n=1,362) were extracted from the KNHANES 2007-2018. Weight classifications were determined by TMI and included overweight and Class I, Class II, and Class III obesity. The standard deviation ...

Aim: Few data are currently available on the reliability of the different anthropometric, instrumental and biochemical indexes in recognizing the presence of the metabolic syndrome (MetS) in severe childhood obesity. The objective of our study was to find out a simple and accurate index to use in deciding whether to initiate a search for MetS in this at-risk population.Patients and Methods: A retrospective study based on...

Pharmacotherapy and the Effects on LDL Levels and Growth in 2 Children with Severe Familial Hypercholesterolemia

Venkatesh Sreedharan Aravind , Yap KP Fabian

Background: Familial Hypercholesterolemia (FH) is an autosomal dominant disorder causing increased levels of total and LDL cholesterol (LDL-C). When onset is in early childhood, it is associated with higher risk of coronary heart disease and hence the emphasis on early identification and strict management to improve the life expectancy. Of the two types of FH, the homozygous variant is the most severe form associated with extremely high levels of LDL.Aim...

Background: More than half of newborns with central congenital hypothyroidism (C-CH) have moderate-to-severe hypothyroidism in the neonatal phase, requiring immediate thyroxine therapy to prevent brain damage. The Israeli newborn screening for CH is based on the measurement of total T4 (TT4) followed by TSH measurement. However, when TSH is within the normal range the physicians are not informed of the results and therefore the diagnosis of C-CH and initiation...

A novel case of hypoglycaemia secondary to a pro-insulin processing disorder

Amin Nadia , Wark Gwen , Church David , Burling Keith , Barker Peter , Williams Gemma , O'Rahilly Stephen

Background: Hypoglycaemia in patients with a high concentration of insulin and low concentration of C-peptide can be secondary to administration of exogenous insulin. This often results in safeguarding measures, with significant consequences for the patient and family. We report a novel case of a patient with symptomatic hypoglycaemia. Initial results suggested high insulin and low C-peptide levels, but subsequent testing revealed a pro-insulin processing diso...
