Early diagnosis and timely treatment of rickets are crucial for correction of the limb deformities. Guidelines exist for nutritional rickets, but the diagnosis and management of the relatively uncommon forms of rickets are complex. This consensus aims to formulate a simplified diagnostic approach for rickets, especially in resource-limited settings. The consensus statement has been formulated by a 29-member committee from the Endocrine Society of Bengal. The process included forming a working group, conducting a literature review, identifying controversies, drafting, and discussion at a consensus meeting. Participants rated their agreement with the clinical practice points, and a 70% consensus was required. Input integration and further review led to the final consensus statements. Children with suspected rickets should initially be examined for distinctive skeletal deformities. The diagnosis of rickets should be confirmed with characteristic radiographic abnormalities. It is advisable to order tests for serum calcium, inorganic phosphorus (Pi), liver function, 25-hydroxyvitamin D (25OHD), parathyroid hormone, creatinine, and potassium in all patients with rickets. In cases of refractory rickets, it is also recommended that assessments be conducted for spot urine calcium, Pi, creatinine, and, blood gas analysis. In children with rickets and metabolic acidosis, tests for glycosuria, uricosuria, aminoaciduria, low molecular weight proteinuria, and albuminuria should be conducted. In children with resistant calciopenic rickets and sufficient serum 25OHD levels, serum 1,25(OH)2D concentration should be tested. 1,25(OH)2 D and fibroblast growth factor 23 estimation is useful for certain forms of phosphopenic rickets.</p>","PeriodicalId":44915,"journal":{"name":"Annals of Pediatric Endocrinology & Metabolism","volume":"29 5","pages":"284-307"},"PeriodicalIF":2.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11541088/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously conducted comprehensive genetic screening of 102 patients with permanent CH born in Kanagawa Prefecture, Japan and identified mutations in several genes in 19 CH patients, including defects in genes encoding dual oxidase 2, thyroglobulin, thyrotropin receptor, thyroid peroxidase, and paired-box 8. Despite these findings, approximately 80% of cases remain unexplained. CH pedigrees unexplained by known genetic forms of CH have been reported in the literature and registered as congenital hypothyroidism, nongoitrous, 3 (CHNG3; %609893) in Online Mendelian Inheritance in Man. We also identified a Japanese pedigree of CH that was compatible with CHNG3. However, the exact genetic cause of CHNG3 was not revealed by standard analysis methods such as exome sequencing and array comparative genomic hybridization. We therefore took a combined approach and analyzed a total of 11 undiagnosed CH pedigrees by whole genome sequencing to analyze a 3-Mb linkage region, and found a disease-causing variant affecting a TTTG microsatellite in a noncoding region on chromosome 15. Further analysis revealed that 13.9% of 989 Japanese CH patients had abnormalities involving the TTTG microsatellite, with a substantial proportion (41.5%) of familial CH cases carrying these mutations.

August 2017 to July 2019 is defined as the pre-COVID-19 pandemic period, while the period from July 2020 to July 2021 is defined as post-COVID-19 or \"during the pandemic.\" Propensity scores were used to match the prepandemic and pandemic groups 1:1 based on age, sex, season of blood collection, and body mass index z-score to compare vitamin D status among subjects.</p><p><strong>Results: </strong>Among 786 eligible children, 506 were matched using propensity scores. There were no significant differences in mean serum 25-hydroxyvitamin D (25(OH) D) levels (20.1±6.5 ng/mL vs. 19.9±6.3 ng/mL, P>0.05) or vitamin D deficiency rates (53.0% vs. 54.9%, P>0.05) between the prepandemic and pandemic groups. Seasonal analysis revealed lower mean serum 25(OH)D levels during the pandemic in winter/spring seasons in comparison to these levels in subjects in prepandemic winter/spring seasons (19.1±3.8 ng/mL vs. 17.2±3.7 ng/mL, P=0.006).</p><p><strong>Conclusion: </strong>During the COVID-19 pandemic, Korean children and adolescents showed similar serum 25(OH)D levels and vitamin D status to the prepandemic period, with a significant decrease in these measures observed in winter/spring seasons only. Prolonged confinement, such as in pandemic circumstances, underscores the need for vigilant monitoring of vitamin D status and supplementation, particularly in high-risk seasons.</p>","PeriodicalId":44915,"journal":{"name":"Annals of Pediatric Endocrinology & Metabolism","volume":"29 4","pages":"220-226"},"PeriodicalIF":2.8,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11374516/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
