The disease results from a pathogenic variant in the ESR1 (estrogen receptor 1) gene, leading to estrogen resistance in individuals possessing the 46, XX karyotype. The alpha receptor, which is predominant in peripheral tissues, is responsible for estrogen action. As a result, pathogenic variants in the ESR1 gene can cause various disorders, such as changes in secondary sexual characteristics, increased concentrations of estrogen and gonadotropins, and delayed bone maturation.CASE PRESENTATIONHere, the case of a 13-year-old girl, with high estrogen and gonadotropin concentrations, lack of breast development, uterine growth and delayed bone age is described. The patient's parents were related. She was found to have a homozygous pathogenic variant in the ESR1 gene located on chromosome 6q25, which interferes with estrogen signaling.CONCLUSIONThis case supports that disruption of ESR1 causes profound estrogen resistance in females.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"189 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data collected included cancer type, diagnosis age, types of chemotherapy, bone marrow transplant or radiation treatment, peak FSH, peak AMH, GnRHa treatment, type of hormone replacement therapy, and if ovarian function recovery occurred.RESULTSThe most common cancer type identified was ALL. The mean age of diagnosis was 8.5±4.3 years and mean age of peak FSH value was 12.6±2.8 years. Most patients (97.2 %) were treated with alkylating agents and 72.2 % received radiation. Most patients (72.2 %) received hormone therapy, and 15.8 % of patients received GnRHa Lupron. Ten patients (27.8 %) had ovarian function recovery. Diagnosis age and treatment type were recovery predictors in multivariate regression modeling. Each year older in age was associated with a 30 % decrease in odds of recovery (OR: 0.7, CI: 0.5-0.95, p=0.035), and alkylating agent treatment without transplant was associated with a 3-fold increase in odds of recovery (OR: 3, CI: 2.7-564, p=0.007).CONCLUSIONSThis retrospective review demonstrates that POI can occur in pediatric cancer survivors, emphasizing the importance of educating patients on potential long-term effects of cancer treatment and importance of routine surveillance.

It occurs as a result of loss-of-function mutations in the ACAN gene, which encodes aggregan protein, which is the basic component of the extracellular matrix in cartilage. It results in disproportionately short stature and skeletal abnormalities. Here, we aimed to present the fourth SEMD-ACAN report in the literature.CASE PRESENTATIONA 9-year-old girl was admitted to our clinic with growth retardation. She was born from a first-degree cousin marriage with severe short stature (41 cm; -3.54 SDS). Her mother also had severe short stature. Her height was 110 cm (-4.6 SDS); she had midface hypoplasia, low-set ears, short neck, short limbs, and central obesity. Biochemical and hormonal tests were normal. Skeletal survey showed moderate platyspondylia, thoracolumbar scoliosis, lumbar lordosis, bilateral femoro-acetabular narrowing, and advanced bone age (10 years). The patient's brother was 100 cm (-3.97 SDS). He had similar but milder clinical findings. Biallelic ACAN variation (c.512C>T; p. Ala171Val) was detected in two siblings by next-generation sequencing. The parents were heterozygous carriers. Before, the heterozygous form of this variant has been reported in a 15-year-old boy with short stature, advanced bone age, and dysmorphic features.CONCLUSIONSSEMD-ACAN is a rare genetic condition that affects bone growth and development and can cause physical and developmental abnormalities.

This study aimed to determine any distinct clinical or biochemical parameters, including GH provocation testing, in children with ADHD on psychostimulants or idiopathic short stature (ISS). Methods Retrospective cross-sectional study of children who had GH provocative testing between 1998 and 2013 at one tertiary paediatric endocrine centre. Clinical data included age, sex, anthropometry, pubertal staging, bone age, diagnostic code as per the European Society Paediatric Endocrinology (ESPE), GH provocation test results, thyroid function tests, serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) levels. Results Four hundred ninety-three subjects underwent GH provocation testing for investigation of short stature to exclude GHD during the study period. Fifty-one children had a diagnosis of ADHD. In the remaining children, the diagnosis was Idiopathic short stature (n=240), GHD +/− hypopituitarism (n=60), and 142 subjects had other causes of short stature. Children with ADHD were older, had higher height and weight SDS and were GH-sufficient. All 51 children with ADHD had a normal serum IGFBP-3, while 20 out of these 51 subjects had a low serum IGF-1. Conclusions GHD in children with ADHD on psychostimulant medication is rare. GH testing in children with ADHD may not be necessary, particularly if serum IGFBP-3 is in the normal range. We suggest IGFBP-3 could be used as a surrogate marker of GH sufficiency in children with ADHD. However, this needs to be confirmed with a larger study group.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of puberty and varying degrees of gonadotropic deficiency are common symptoms of this disorder. Heterogeneity exists in the clinical presentation of the different clinical subtypes and multiple genes have been implicated in CHH. A number of genetic defects have been identified as causes normosmic CHH, including mutations of GnRHR, GNRH1, KISS1R, KISS1, TACR3 and TAC3. Loss-of-function mutations in KISS1R gene are a rare cause of normosmic CHH. Case presentation We described an 11.5 years old Chinese patient who presented at birth with micropenis, microorchidia and bilateral cryptorchidism. Whole-exome sequencing was also performed and identified a homozygous mutation of KISS1R gene, c.1010_1028del (p.V337Afs*82). The variant was predicted as “deleterious” and classified as “likely pathogenic”. This variant has never been reported in patients with CHH.

Methods In a school population-based study in Zhongshan, China, we recruited 1,722 girls in grades 1–3 by a multistage stratified cluster random sampling method. Participants completed self-reported PDS questionnaire prior to physical examination. Breast development was evaluated by a female pediatrician combined with ultrasound examination for overweight/obese girls; pubic hair development was evaluated. Otherwise, we tested follicle-stimulating hormone (FSH) and luteinizing hormone (LH) for some participants. Results We observed a weak association between Tanner-derived composite stage (TDCS) and puberty category scores (PCS) (τ=0.288, p<0.001) among all girls. There was correlation (τ=0.314, p=0.001) between ultrasound-derived composite stage (UDCS) and PCS among overweight/obese girls. Moreover, among overweight/obese girls, PCS was positively correlated with LH (r=0.265, p=0.008), but not FSH (r=0.155, p=0.123), and when the basal LH value was greater than 0.3 mIU/mL, the proportion of PCS stage ≥2 (9/18) was higher than the proportion of TDCS ≥2 (5/18). As for the determination of pubertal onset, when UDCS was used as the gold standard, the specificity of PCS was 0.86 and positive predictive value was 90.00 %. Conclusions There was a weak correlation between PCS and TDCS among girls early adolescence.

Objectives To compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic. Methods Cross-sectional study including 143 children. Groups were divided into (a) obese: biphasic (B-Ob) (n=55) and monophasic (M-Ob) (n=50), (b) without obesity: biphasic (B-NonOb) (n=20) and monophasic (M-NonOb) (n=18). Results Late glucose peak was more frequent in the M-Ob group (p<0.001). Glucose levels ≥155 mg/dL and MetS were more frequent in the M-Ob group but did not show significance. The groups with obesity (biphasic and monophasic) had higher indices of insulin resistance and insulin secretion compared to the nonobese groups (biphasic and monophasic) (p<0.001). AUC glucose was higher in the M-Ob group (p<0.05), and AUC insulin was higher in the M-NonOb group. oDI (Matsuda) was significantly lower in the M-Ob group compared to the other groups (p<0.001), and oDI-HOMA IR was higher in M-NonOb group (p=0.03). Conclusions All OGTT parameters could help to identify Mexican children at increased risk of developing T2DM, not only fasting plasma glucose and 2 h glucose. M-Ob in non-T2DM Mexican children reflects an early defect in glucose metabolism. Higher level of IR indexes in M-NonOb vs. B-NonOb could indicate an increased risk for T2DM of genetic origin.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
