Similarly, the height velocity (HV), insulin-like growth factor-1 standard deviation score (IGF-1 SDS), and bone age to chronological age ratio (BA/CA ratio) underwent significant augmentations (p<0.01). Remarkably, no signs of rapid bone maturation were detected during the 5-year observation.

This report aimed to investigate peak GH levels in GHRP2T in adolescents.Methods: Clinical data of adolescents after onset of puberty who underwent GHRP2T at our institution from May 2010 to March 2023 were collected retrospectively. Subjects were classified into three groups according to underlying diseases.Results: A total of 23 patients were included: 12 in organic or genetic GHD (o/gGHD) group, three in idiopathic GHD (iGHD) group, and eight in short stature (SS) group. The median GH peak levels were 3.4 ng/mL in o/gGHD group, 88.9 ng/mL in iGHD group, and 90.1 ng/mL in SS group, indicating a robust response of GH peak levels in iGHD and SS groups. Two patients exceeded the cut-off for GHRP2T but below for other GHT, indicating the current cut-off for GHRP2T may miss some GHD patients.Conclusions: The GH response to GHRP2T in adolescents except the o/gGHD group may be robustly responsive.

The predictive power of 11 different glucose and lipid-related indicators for predicting elevated ALT was examined using receiver operating characteristic (ROC) curve.Results: In the total sample non-HDL-C, non-HDL-C/HDL-C, and TC/HDL-C showed the largest area under the curve (AUC) for elevated ALT detection, with 0.731 (cut-off, 129.5 mg/dL), 0.706, and 0.706, respectively. In girls, non-HDL-C had the highest predictive value (AUC, 0.741, cut-off, 129.5 mg/dL). Among boys, non-HDL-C/HDL-C and TC/HDL-C showed the largest AUC of 0.753 with optimum cut-off values of 2.63 and 3.63, respectively.Conclusions: The findings of this study suggest that non-HDL-C, non-HDL-C/HDL-C, and TC/HDL-C can be predictors of elevated ALT in the pediatric population. These indices can be useful in large population-based studies for predicting children and adolescents at risk of fatty liver.","PeriodicalId":50096,"journal":{"name":"Journal of Pediatric Endocrinology & Metabolism","volume":" ","pages":"597-604"},"PeriodicalIF":1.3,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141460456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
