Insulin clearance at randomisation and in response to treatment in youth with type 2 diabetes: a secondary analysis of the TODAY randomised clinical trial.

Aims/hypothesis: Insulin resistance and compensatory hyperinsulinaemia are core features leading to beta cell failure in youth-onset type 2 diabetes. Insulin clearance (IC) is also a key regulator of insulin concentrations, but few data exist on IC in youth-onset type 2 diabetes. In a secondary analysis of our Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) randomised clinical trial, we investigated potential sex-, race-, ethnicity- and treatment-related differences in IC in youth-onset type 2 diabetes and aimed to identify metabolic phenotypes associated with IC at baseline and in response to metformin, metformin plus a lifestyle intervention, and metformin plus rosiglitazone.

Liraglutide for Children 6 to <12 Years of Age with Obesity - A Randomized Trial.

Background: No medications are currently approved for the treatment of nonmonogenic, nonsyndromic obesity in children younger than 12 years of age. Although the use of liraglutide has been shown to induce weight loss in adults and adolescents with obesity, its safety and efficacy have not been established in children.

Methods: In this phase 3a trial, which consisted of a 56-week treatment period and a 26-week follow-up period, we randomly assigned children (6 to <12 years of age) with obesity, in a 2:1 ratio, to receive either once-daily subcutaneous liraglutide at a dose of 3.

Dulaglutide and Glomerular Hyperfiltration, Proteinuria, and Albuminuria in Youth With Type 2 Diabetes: Post Hoc Analysis of the AWARD-PEDS Study.

Objective: To examine changes in glomerular hyperfiltration and other measures of kidney function in youth with type 2 diabetes treated with dulaglutide or placebo.

Research Design And Methods: Post hoc analysis was performed on kidney laboratory data from 154 youths (age 10-18 years) with type 2 diabetes enrolled in a completed placebo-controlled glycemic control trial of dulaglutide.

Results: Mean estimated glomerular filtration rate (eGFR) decreased from baseline to 26 weeks in participants treated with dulaglutide versus placebo (-5.

Semaglutide for management of obesity in adolescents: efficacy, safety, and considerations for clinical practice.

Purpose Of Review: The purpose of this review is to describe the existing limited data related to the use of semaglutide in adolescents with obesity, supplementing with findings from adult studies of semaglutide use.

Recent Findings: Semaglutide, as a once weekly subcutaneous injection for weight management, effectively reduces body mass index (BMI) while improving hyperglycemia, elevated alanine aminotransferase levels, hyperlipidemia, and quality of life in youth with obesity. As of this review, only one large randomized clinical trial of semaglutide in youth has been completed, with a follow-up duration of 68 weeks.

Child Opportunity Index and clinical characteristics at diabetes diagnosis in youth: type 1 diabetes versus type 2 diabetes.

Introduction: Among youth with type 1 diabetes (T1D), longitudinal poor glycemic control is associated with adverse socioeconomic conditions at the neighborhood level. Child Opportunity Index (COI), which encompasses measures of education, health, environment, social, and economic factors, is associated with obesity in youth but has not been evaluated in youth with new-onset T1D or type 2 diabetes (T2D). We hypothesized that lower COI would be associated with adverse clinical outcomes at diabetes diagnosis, and due to differing risk factors and pathophysiology, that youth with new-onset T2D would have lower COI than youth with T1D.

Estimating insulin sensitivity and β-cell function from the oral glucose tolerance test: validation of a new insulin sensitivity and secretion (ISS) model.

Efficient and accurate methods to estimate insulin sensitivity () and β-cell function (BCF) are of great importance for studying the pathogenesis and treatment effectiveness of type 2 diabetes (T2D). Existing methods range in sensitivity, input data, and technical requirements. Oral glucose tolerance tests (OGTTs) are preferred because they are simpler and more physiological than intravenous methods.

Impact of youth onset type 2 diabetes during pregnancy on microvascular and cardiac outcomes.

Aims: To examine the impact of pregnancy on microvascular and cardiovascular measures in women with youth-onset T2D.

Methods: Microvascular and cardiovascular measures were compared in in a cohort of 116 women who experienced a pregnancy of ≥ 20 weeks gestation and 291 women who did not among women in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

Results: Cox regression models adjusted for participant characteristics at baseline including age, race/ethnicity, household income, diabetes duration, HbA1c (>6%), and BMI, demonstrated those who experienced pregnancy had 2.

Pediatric Obesity: Complications and Current Day Management.

Obesity affects approximately 1 in 5 youth globally and increases the risk of complications during adolescence and young adulthood, including type 2 diabetes, dyslipidemia, hypertension, non-alcoholic fatty liver disease, obstructive sleep apnea, and polycystic ovary syndrome. Children and adolescents with obesity frequently experience weight stigma and have an impaired quality of life, which may exacerbate weight gain. Pediatric obesity is typically defined using sex-, age-, and population-specific body mass index percentiles.

Estimating Insulin Sensitivity and Beta-Cell Function from the Oral Glucose Tolerance Test: Validation of a new Insulin Sensitivity and Secretion (ISS) Model.

Efficient and accurate methods to estimate insulin sensitivity (S) and beta-cell function (BCF) are of great importance for studying the pathogenesis and treatment effectiveness of type 2 diabetes. Many methods exist, ranging in input data and technical requirements. Oral glucose tolerance tests (OGTTs) are preferred because they are simpler and more physiological.

Reducing BMI below the obesity threshold in adolescents treated with once-weekly subcutaneous semaglutide 2.4 mg.

Objective: The aim of this study was to examine how improvement in BMI with the glucagon-like peptide-1 receptor agonist semaglutide translated to changes in BMI category in a post hoc analysis of the double-blind, phase 3a randomized controlled Semaglutide Treatment Effect in People with obesity (STEP) TEENS trial.

Methods: Adolescents with obesity received once-weekly subcutaneous semaglutide 2.4 mg or placebo plus lifestyle intervention, which comprised counseling in healthy nutrition and a goal of 60 minutes of moderate- to high-intensity physical activity per day.

Reproducibility of Glycemic Measures Among Dysglycemic Youth and Adults in the RISE Study.

Aims: Previous work found poor reproducibility for measures of glycemia in individuals at risk for dysglycemia. Differences between youth and adults have not been assessed. Using youth and adults in the Restoring Insulin Secretion Study, we tested variability and classification concordance for hemoglobin A1C (HbA1c), fasting and 2-hour glucose from oral glucose tolerance tests (OGTTs).

Initial Insights into the Genetic Variation Associated with Metformin Treatment Failure in Youth with Type 2 Diabetes.

Metformin is the first-line treatment for type 2 diabetes (T2D) in youth but with limited sustained glycemic response. To identify common variants associated with metformin response, we used a genome-wide approach in 506 youth from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study and examined the relationship between T2D partitioned polygenic scores (pPS), glycemic traits, and metformin response in these youth. Several variants met a suggestive threshold ( < 1 × 10), though none including published adult variants reached genome-wide significance.

Race- and Neighborhood-Related Disparities Spanning the COVID-19 Pandemic: Trajectories of Combined Glycemic Control and BMI in Youth With Diabetes.

Objective: To use combined glycemic (HbA1c) and BMI z-score (BMIZ) trajectories spanning the coronavirus disease 2019 (COVID-19) pandemic to identify high-risk subgroups of adolescents with diabetes.

Research Design And Methods: Retrospective cohort of adolescents 10-19 years old with type 1 and type 2 diabetes with one or more visits at a large pediatric hospital from January 2018 through February 2020 (prepandemic) and April 2020 through August 2021 (pandemic). Group-based trajectory models were used to identify latent classes of combined BMIZ and HbA1c trajectories.

Long-Term Retention of Young Adult Study Participants with Youth-Onset Type 2 Diabetes: Results from the TODAY2 Study.

Introduction: The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) trial examined the effects of three treatment arms in a group of racially and ethnically diverse adolescents and youth with type 2 diabetes mellitus. TODAY2 was an observational follow-up study reporting outcomes and complications in these participants after having diabetes for approximately 13 years. Participant retention was essential to fulfill this objective.

Anti-obesity pharmacotherapy for treatment of pediatric type 2 diabetes: Review of the literature and lessons learned from adults.

Type 2 diabetes mellitus (T2DM) in adolescents is a more rapidly progressive disease, associated with earlier and higher rates of microvascular complications than in adults. As obesity is a significant risk factor for T2DM development and progression, the American Diabetes Association (ADA) recommends anti-obesity medications (AOMs) as adjuvant therapy for adults with both T2DM and overweight/obesity. In adults, the addition of AOMs to a diabetes regimen can improve glycemic control, reduce weight, and decrease anti-diabetes medication use.

Once-Weekly Semaglutide in Adolescents with Obesity.

Background: A once-weekly, 2.4-mg dose of subcutaneous semaglutide, a glucagon-like peptide-1 receptor agonist, is used to treat obesity in adults, but assessment of the drug in adolescents has been lacking.

Methods: In this double-blind, parallel-group, randomized, placebo-controlled trial, we enrolled adolescents (12 to <18 years of age) with obesity (a body-mass index [BMI] in the 95th percentile or higher) or with overweight (a BMI in the 85th percentile or higher) and at least one weight-related coexisting condition.

ISPAD Clinical Practice Consensus Guidelines 2022: Type 2 diabetes in children and adolescents.

Since the 2018 ISPAD guidelines on this topic, follow-up of large cohorts from around the globe have continued informing the current incidence and prevalence of co-morbidities and complications in young adults with youth-onset type 2 diabetes (T2D). This chapter focuses on the risk factors, diagnosis and presentation of youth-onset T2D, the initial and subsequent management of youth-onset T2D, and management of co-morbidities and complications. We include key updates from the observational phase of the multi-center Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial, the SEARCH for Diabetes in Youth (SEARCH) study and new data from the Restoring Insulin Secretion (RISE) study, a head-to-head comparison of youth onset vs adult-onset T2D.

Anthropometric Equations to Predict Visceral Adipose Tissue in European and American Youth.

Objective: To investigate whether prediction equations including a limited but selected number of anthropometrics that consider differences in subcutaneous abdominal adipose tissue may improve prediction of the visceral adipose tissue (VAT) in youth.

Study Design: Anthropometrics and abdominal adipose tissue by MRI were available in 7-18 years old youth with overweight or obesity: 181 White Europeans and 186 White and Black Americans. Multivariable regressions were performed to develop and validate the VAT anthropometric predictive equations in a cross-sectional study.

Weight loss and β-cell responses following gastric banding or pharmacotherapy in adults with impaired glucose tolerance or type 2 diabetes: a randomized trial.

Objective: The extent to which weight loss contributes to increases in insulin sensitivity (IS) and β-cell function after surgical or medical intervention has not been directly compared in individuals with impaired glucose tolerance or newly diagnosed type 2 diabetes.

Methods: The Restoring Insulin Secretion (RISE) Study included adults in the Beta-Cell Restoration Through Fat Mitigation Study (n = 88 randomized to laparoscopic gastric banding or metformin [MET]) and the Adult Medication Study (n = 267 randomized to placebo, MET, insulin glargine/MET, or liraglutide + MET [L + M]). IS and β-cell responses were measured at baseline and after 12 months by modeling of oral glucose tolerance tests and during arginine-stimulated hyperglycemic clamps.

Once-Weekly Dulaglutide for the Treatment of Youths with Type 2 Diabetes.

Background: The incidence of type 2 diabetes mellitus is increasing among youths. Once-weekly treatment with dulaglutide, a glucagon-like peptide-1 receptor agonist, may have efficacy with regard to glycemic control in youths with type 2 diabetes.

Methods: In a double-blind, placebo-controlled, 26-week trial, we randomly assigned participants (10 to <18 years of age; body-mass index [BMI], >85th percentile) being treated with lifestyle modifications alone or with metformin, with or without basal insulin, in a 1:1:1 ratio to receive once-weekly subcutaneous injections of placebo, dulaglutide at a dose of 0.
