Standard calculation methods based on the total daily insulin dose (TDD) often fall short for children. This study examined insulin pump settings for ICR and ISF in pediatric patients, considering diurnal variation, age, sex, and body mass index (BMI). The goal was to provide data-driven recommendations for initial bolus settings. <b><i>Methods:</i></b> We analyzed insulin pump settings in 7697 pediatric patients with type 1 diabetes in the DPV registry (Diabetes Prospective Follow-up) from Germany, Austria, Switzerland, and Luxembourg. Patients aged 1 to <18 years, postremission (diabetes duration >1 year, insulin dose ≥0.5 IU/kg/d), with good metabolic control (HbA1c ≤7.5%), using insulin pumps with short-acting analog insulin in 2023, were included. Automated insulin delivery system users were excluded. Patients were grouped by age (<6, 6 to <12, 12 to <18 years), BMI percentiles (<P25, P25-75, >P75), and sex. <b><i>Results:</i></b> Older children required more insulin, with lower ICRs and ISFs. Insulin requirements peaked in the morning with the lowest ICR and ISF, with medians (interquartile ranges): <6 years: 11.2 g carbs/IU (9.1-14.0) and 1:150 mg/dL (70-228); 6 to <12 years: 8.7 g carbs/IU (7.0-10.7) and 1:90 (50-140); and 12 to <18 years: 6.1 g carbs/IU (5.0-7.7) and 1:50 (40-80). ISF was highest in the late evening in all age groups, while a higher BMI-SDS was associated with a lower ISF. Girls above 6 years had lower ICR but similar ISF to that of boys. The factor obtained by multiplying ISF and TDD was comparable in all age groups and BMI categories. <b><i>Conclusion:</i></b> Our real-world findings on CSII settings in a large cohort of children with sufficient metabolic control highlight the inadequacy of a single TDD-based calculation formula, as insulin requirements varied by age, time of day, sex, and BMI. These findings may serve as a reference for commonly used age-dependent parameters for clinicians in establishing initial CSII settings before individualized dose titration and optimization.</p>","PeriodicalId":11159,"journal":{"name":"Diabetes technology & therapeutics","volume":" ","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discovery and first use of insulin in humans 102 years ago marked a revolutionary course of treatment for the disease, and although the formulations and delivery systems have advanced, insulin administration remains the standard of care today. While improved treatment options represent notable progress in T1D management, finding a functional cure for the disease remains the ultimate goal. Approaches to curing T1D have historically focused on blunting the autoimmune response, although sustained effects of immune modulation have proven elusive. Islet transplant therapies have also proven effective, although a lack of available donor tissue and the need for immunosuppression to prevent both host-graft rejection and the autoimmune response have reserved such treatments for those who already require immunosuppressive regimens for other reasons or undergo severe hypoglycemic events in conjunction with hypoglycemic unawareness. With the advent of human stem cell research, the focus has shifted toward generating an abundance of allogeneic, functional beta-like cells that can be transplanted into the patients. Immunoisolation devices have also shown some promise as a method of preventing immune rejection and the autoimmune destruction of transplanted cells. Finally, advances in new immune therapies, if used in the early stages of T1D progression, have proven to delay the onset of diabetes. Stem cell-based therapies are a promising approach to curing T1D. The ongoing clinical trials show some success, although they currently require immunosuppressant agents. Encapsulation devices provide a method of immunoisolation that does not require immunosuppression; however, the devices tested thus far eventually lead to cell death and fibrotic tissue growth. Substantial research efforts are underway to develop new approaches to protect the stem cell-derived beta cells upon transplantation.</p>","PeriodicalId":11159,"journal":{"name":"Diabetes technology & therapeutics","volume":" ","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
