Abstract
OBJECTIVES To identify determinants of the course of Type 2 diabetes in Indian adolescents. METHODS Records of 37 adolescents (24 boys; 29 post pubertal and eight pubertal) with Type 2 diabetes (initial HbA1C 10.1 ± 1.9% and BMI SDS 2.0 ± 0.8; family history of diabetes in 33, 89.2%) diagnosed at 15.2 ± 2.5 y and followed up for 3.8 ± 2.2 y till 19.1 ± 3.3 y of age, were reviewed. RESULTS Initial treatment included insulin in 11 (29.7%), metformin alone in 22 (59.5%), and a combination of anti-diabetic medication in four (10.8%). Eleven subjects (29.7%) achieved remission at a median period of 5.3 mo (IQR- 17.13) after diagnosis; six of these relapsed within 0.9 ± 0.3 (range 0.4-1.3) y. The proportion of subjects requiring multiple anti-diabetic agents increased over follow-up (19% at six months, 32.5% at one year, 50% at two years, 59.1% at three, and 64.8% at four years), with the need for combination therapy after 0.9 ± 1.4 y. At the last follow-up, five were off treatment (13.5%), 10 (27%) were on metformin alone, and 22 (59.5%) were on multiple medications. The need for combination therapy at the last follow-up was lower in subjects with remission (27% against 73.1%, p = 0.02). CONCLUSIONS The findings of this study suggest delayed presentation and rapid progression of Type 2 diabetes in Indian adolescents. Diagnosis on screening and achievement of remission were predictors of good outcome.

Early-Onset Type 2 Diabetes and Tirzepatide Treatment: A Post Hoc Analysis From the SURPASS Clinical Trial Program. Diabetes Care 2024; 47:1056-1064. [PMID: 38639997 PMCID: PMC11116907 DOI: 10.2337/dc23-2356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 03/21/2024] [Indexed: 04/20/2024]
Abstract
OBJECTIVE We evaluated baseline characteristics of participants with early-onset type 2 diabetes (T2D) from the SURPASS program and tirzepatide's effects on glycemic control, body weight (BW), and cardiometabolic markers. RESEARCH DESIGN AND METHODS This post hoc analysis compared baseline characteristics and changes in mean HbA1c, BW, waist circumference (WC), lipids, and blood pressure (BP) in 3,792 participants with early-onset versus later-onset T2D at week 40 (A Study of Tirzepatide [LY3298176] in Participants With Type 2 Diabetes Not Controlled With Diet and Exercise Alone [SURPASS-1] and A Study of Tirzepatide [LY3298176] Versus Semaglutide Once Weekly as Add-on Therapy to Metformin in Participants With Type 2 Diabetes [SURPASS-2]) or week 52 (A Study of Tirzepatide [LY3298176] Versus Insulin Degludec in Participants With Type 2 Diabetes [SURPASS-3]). Analyses were performed by study on data from participants while on assigned treatment without rescue medication in case of persistent hyperglycemia. RESULTS At baseline in SURPASS-2, participants with early-onset versus later-onset T2D were younger with longer diabetes duration (9 vs. 7 years, P < 0.001) higher glycemic levels (8.5% vs. 8.2%, P < 0.001), higher BW (97 vs. 93 kg, P < 0.001) and BMI (35 vs. 34 kg/m2, P < 0.001), and a similarly abnormal lipid profile (e.g., triglycerides 167 vs. 156 mg/dL). At week 40, similar improvements in HbA1c (-2.6% vs. -2.4%), BW (-14 vs. -13 kg), WC (-10 vs. -10 cm), triglycerides (-26% vs. -24%), HDL (7% vs. 7%), and systolic BP (-6 vs. -7 mmHg) were observed in both subgroups with tirzepatide. CONCLUSIONS Despite younger age, participants with early-onset T2D from the SURPASS program had higher glycemic levels and worse overall metabolic health at baseline versus those with later-onset T2D. In this post hoc analysis, similar improvements in HbA1c, BW, and cardiometabolic markers were observed with tirzepatide, irrespective of age at T2D diagnosis. Future studies are needed to determine long-term outcomes of tirzepatide in early-onset T2D.

Abstract
Classifying diabetes at diagnosis is crucial for disease management but increasingly difficult due to overlaps in characteristics between the commonly encountered diabetes types. We evaluated the prevalence and characteristics of youth with diabetes type that was unknown at diagnosis or was revised over time. We studied 2073 youth with new-onset diabetes (median age [IQR] = 11.4 [6.2] years; 50% male; 75% White, 21% Black, 4% other race; overall, 37% Hispanic) and compared youth with unknown versus known diabetes type, per pediatric endocrinologist diagnosis. In a longitudinal subcohort of patients with data for ≥ 3 years post-diabetes diagnosis (n = 1019), we compared youth with steady versus reclassified diabetes type. In the entire cohort, after adjustment for confounders, diabetes type was unknown in 62 youth (3%), associated with older age, negative IA-2 autoantibody, lower C-peptide, and no diabetic ketoacidosis (all, p < 0.05). In the longitudinal subcohort, diabetes type was reclassified in 35 youth (3.4%); this was not statistically associated with any single characteristic. In sum, among racially/ethnically diverse youth with diabetes, 6.4% had inaccurate diabetes classification at diagnosis. Further research is warranted to improve accurate diagnosis of pediatric diabetes type.

Abstract
The incidence rates of type 2 diabetes among adults in Asia have been stable, but the rates in youth and young adults have increased. In territory-wide surveillance in Hong Kong, Special Administrative Region of People's Republic of China, all-cause mortality rates among people with diabetes have exhibited a declining trend in the past 15 years, with a narrowing in the mortality gap between people with and without diabetes. At the same time, the improvement in survival resulted in a changing age structure and disease profile of people with diabetes, towards an increasing proportion of older people with long diabetes duration and multi-morbidities. Reductions in event rates were not observed in the youngest age group who also had the least gains in risk factor control and uptake in organ protective drugs over time. A young age at diabetes diagnosis, associated with exposure to high glycemic burden from an early age, predicted higher risks of complications and premature mortality compared with later-onset of diabetes. People presenting with type 2 diabetes below 40 years of age were 5-fold more likely to die and their life expectancy was shortened by 8 years than age-matched counterparts without diabetes. Analysis of population-based data in Hong Kong Chinese identified hypertension followed by chronic kidney disease as the leading contributor to mortality in young people, indicating that efforts to optimize non-glycemic risk factors and organ protection are as important in young individuals as it is in the older population.

Abstract
Statins are a class of medications primarily used in adults to lower cholesterol levels and reduce the risk of cardiovascular events. However, the use of statins in children is generally limited and carefully considered despite the well-documented anti-inflammatory, anti-angiogenic, and pro-apoptotic effects, as well as their effect on cell signaling pathways. These multifaceted effects, known as pleiotropic effects, encompass enhancements in endothelial function, a significant reduction in oxidative stress, the stabilization of atherosclerotic plaques, immunomodulation, the inhibition of vascular smooth muscle proliferation, an influence on bone metabolism, anti-inflammatory properties, antithrombotic effects, and a diminished risk of dementia. In children, recent research revealed promising perspectives on the use of statins in various conditions including neurological, cardiovascular, and oncologic diseases, as well as special situations, such as transplanted children. The long-term safety and efficacy of statins in children are still subjects of ongoing research, and healthcare providers carefully assess the individual risk factors and benefits before prescribing these medications to pediatric patients. The use of statins in children is generally less common than in adults, and it requires close monitoring and supervision by healthcare professionals. Further research is needed to fully assess the pleiotropic effects of statins in the pediatric population.

Abstract
BACKGROUND: Incidence of type 2 diabetes (T2D) in children and adolescents is increasing, but treatment options are limited. METHODS: This was a 26-week, phase 3 trial with a 26-week extension among patients (10 to 17 years of age) with uncontrolled T2D (A1C 6.5 to 10.5%) receiving metformin, insulin, or both. Participants were randomly assigned 1:1:1 to 5 mg of dapagliflozin (N=81), 2.5 mg of saxagliptin (N=88), or placebo (N=76). Patients in active treatment groups with A1C ≥7% at week 12 were further randomly assigned 1:1 at week 14 to continue the dose or up-titrate to a higher dose (10 mg of dapagliflozin or 5 mg of saxagliptin). The primary end point was change in A1C at week 26. Safety was assessed over 52 weeks. RESULTS: At week 26, the difference versus placebo in adjusted mean change in A1C was −1.03 percentage points (95% confidence interval [CI], −1.57 to −0.49; P<0.001) for dapagliflozin and −0.44 percentage points (95% CI, −0.93 to 0.05; P=0.078) for saxagliptin. Adverse events (AEs) and serious AEs occurred in 72.8% and 8.6% of patients receiving dapagliflozin, 69.3% and 8.0% of patients receiving saxagliptin, and 71.1% and 6.6% of patients receiving placebo. Severe hypoglycemia occurred in 4.9%, 4.5%, and 7.9% of patients in each group, respectively. Over 52 weeks, the most common AE was headache (dapagliflozin 14.8%; placebo 5.3%). Most events were mild and none was considered serious or resulted in discontinuation. CONCLUSIONS: Dapagliflozin, but not saxagliptin, showed significant improvement in A1C compared with placebo. Nonserious headaches were more common in participants treated with dapagliflozin than in those receiving placebo. (Funded by AstraZeneca; ClinicalTrials.gov number, NCT03199053.)

Abstract
Type 2 diabetes (T2D) in youth is a global health concern characterized by an increasing incidence and prevalence, especially among disadvantaged socioeconomic subgroups. Moreover, youth-onset T2D is more aggressive and causes earlier, more severe long-term cardio-renal complications compared with T2D in adults. The therapeutic options available are limited and often inadequate, partially due to the numerous challenges in implementing clinical trials for this vulnerable patient population. Over the last few years, a significant effort has been made to develop new effective drugs for children and adolescents with T2D. Specifically, a number of studies are currently generating new data to address the urgent unmet medical need for optimal management of this disease. This review describes the central features of youth-onset T2D and summarizes the available treatments and ongoing studies in pediatric patients.

Abstract
Diabetes is a highly heterogeneous condition; yet, it is diagnosed by measuring a single blood-borne metabolite, glucose, irrespective of aetiology. Although pragmatically helpful, disease classification can become complex and limit advances in research and medical care. Here, we describe diabetes heterogeneity, highlighting recent approaches that could facilitate management by integrating three disease models across all forms of diabetes, namely, the palette model, the threshold model and the gradient model. Once diabetes has developed, further worsening of established diabetes and the subsequent emergence of diabetes complications are kept in check by multiple processes designed to prevent or circumvent metabolic dysfunction. The impact of any given disease risk factor will vary from person-to-person depending on their background, diabetes-related propensity, and environmental exposures. Defining the consequent heterogeneity within diabetes through precision medicine, both in terms of diabetes risk and risk of complications, could improve health outcomes today and shine a light on avenues for novel therapy in the future.

Abstract
AIMS We compared beta-cell function in Chinese with type 2 diabetes diagnosed at age < 40 years (young-onset diabetes, YOD) and ≥ 40 years (late-onset diabetes, LOD). METHODS In this cross-sectional study, we selected participants from two cohorts of people with type 2 diabetes recruited in 1996-2012 (n = 4,376) and 2020-2021 (n = 794). Multivariable linear regression models were applied to compare homeostasis model assessment of beta-cell function (HOMA2-%B) and fasting plasma C-peptide across diabetes duration at enrolment between YOD and LOD. RESULTS The YOD group (n = 1,876, mean [SD] age: 39.9 [7.5] years, median [IQR] diabetes duration: 6 [2-12] years) was more likely to have family history of diabetes (61.6 % vs 43.6 %), obesity (41.9 % vs 26.8 %), dyslipidaemia (61.7 % vs 54.4 %), and worse glycaemic control (mean HbA1c 7.7 % vs 7.4 %) than those with LOD (n = 3,294, age: 60.8 [10.6] years, diabetes duration: 5 [1-10] years). When compared to people with LOD, HOMA2-%B and fasting plasma C-peptide were lower in the YOD group, consistently among those with BMI < 27.5 kg/m2 and HOMA2-IR ≤ 1.6 (median value), adjusted for year at enrolment, sex, diabetes duration, family history of diabetes, HbA1c, weight and lipid indices (p < 0.01). Cross-sectionally, the slopes of decline in HOMA2-%B by diabetes duration were greater in YOD than LOD among individuals with BMI < 27.5 kg/m2 (p-interaction = 0.015). CONCLUSIONS Chinese with YOD had accelerated loss of beta-cell function than those with LOD especially in non-obese individuals.

Effect of Early Glycemic Control in Youth-Onset Type 2 Diabetes on Longer-Term Glycemic Control and β-Cell Function: Results From the TODAY Study. Diabetes Care 2023; 46:1507-1514. [PMID: 37378967 PMCID: PMC10369125 DOI: 10.2337/dc23-0560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 05/15/2023] [Indexed: 06/29/2023]
Abstract
OBJECTIVE Little is known about the impact of early attainment of tight glycemic control on long-term β-cell function and glycemic control in youth-onset type 2 diabetes. We examined the effect of the initial 6 months of glycemic control on β-cell function and glycemic control longitudinally over 9 years and the impact of sex, race/ethnicity, and BMI on these relationships in adolescents with youth-onset type 2 diabetes in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. RESEARCH DESIGN AND METHODS Oral glucose tolerance tests were performed longitudinally through year 9 to derive estimates of insulin sensitivity and secretion. Early glycemia was defined by mean HbA1c during the first 6 months postrandomization, categorized into five HbA1c groups (<5.7%, 5.7 to <6.4%, 6.4 to <7.0%, 7.0 to <8.0%, and ≥8.0%). The long-term period was defined as the period between years 2 and 9. RESULTS A total of 656 participants (64.8% female, baseline mean age 14 years, diabetes duration <2 years) had longitudinal data available over an average of 6.4 ± 3.2 years of follow-up. HbA1c significantly increased in all early glycemic groups during years 2-9, with a steeper increase (+0.40%/year) among participants with the tightest initial control (mean early HbA1c <5.7%), in parallel to a decline in the C-peptide-derived disposition index. Nevertheless, the lower HbA1c categories continued to have relatively lower HbA1c over time. CONCLUSIONS Early tight glycemic control in the TODAY study was related to β-cell reserve and translated to better long-term glycemic control. However, tight early glycemic control on the randomized treatment in the TODAY study did not prevent deterioration of β-cell function.

Abstract
Classifying diabetes at diagnosis is crucial for disease management but increasingly difficult due to overlaps in characteristics between the commonly encountered diabetes types. We evaluated the prevalence and characteristics of youth with diabetes type that was unknown at diagnosis or was revised over time. We studied 2073 youth with new-onset diabetes (median age [IQR]=11.4 [6.2] years; 50% male; 75% White, 21% Black, 4% other race; overall, 37% Hispanic) and compared youth with unknown versus known diabetes type, per pediatric endocrinologist diagnosis. In a longitudinal subcohort of patients with data for ≥3 years post-diabetes diagnosis (n=1019), we compared youth with unchanged versus changed diabetes classification. In the entire cohort, after adjustment for confounders, diabetes type was unknown in 62 youth (3%), associated with older age, negative IA-2 autoantibody, lower C-peptide, and no diabetic ketoacidosis (all, p<0.05). In the longitudinal subcohort, diabetes classification changed in 35 youth (3.4%); this was not statistically associated with any single characteristic. Having unknown or revised diabetes type was associated with less continuous glucose monitor use on follow-up (both, p<0.004). In sum, among racially/ethnically diverse youth with diabetes, 6.5% had imprecise diabetes classification at diagnosis. Further research is warranted to improve accurate diagnosis of pediatric diabetes type.

Higher incidence of cardiovascular-kidney complications in Chinese with youth-onset type 2 diabetes versus youth-onset type 1 diabetes attenuated by control of cardio-metabolic risk factors: a population-based prospective cohort study in Hong Kong. Diabetes Res Clin Pract 2023:110728. [PMID: 37217017 DOI: 10.1016/j.diabres.2023.110728] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 05/09/2023] [Accepted: 05/18/2023] [Indexed: 05/24/2023]
Abstract
AIMS To determine and compare the incidence of diabetes complications in Chinese with youth-onset type 2 and type 1 diabetes. METHODS We conducted a population-based prospective cohort study, including 1,260 people with type 2 diabetes and 1,227 with type 1 diabetes diagnosed at age <20 years who underwent metabolic and complication assessment in Hong Kong Hospital Authority between 2000 and 2018. They were followed for incident cardiovascular disease (CVD), end-stage kidney disease (ESKD) and all-cause death until 2019. Multivariable Cox regression analysis was applied to compare the risks of these complications in type 2 versus type 1 diabetes. RESULTS People with type 1 diabetes (median age: 20 years, median diabetes duration: 9 years) and type 2 diabetes (median age: 21 years, median diabetes duration: 6 years) were followed for a mean period of 9.2 and 8.8 years respectively. The risks of CVD (HR [95% CI] 1.66 [1.01-2.72]) and ESKD (HR 1.96 [1.27-3.04]) but not death (HR 1.10 [0.72-1.67]) were higher in type 2 versus type 1 diabetes, adjusted for age at diagnosis, diabetes duration and sex. The association became nonsignificant with further adjustment for glycaemic and metabolic control. Youth-onset type 2 diabetes conferred mortality excess (standardized mortality ratio 4.15 [3.28-5.17]) to age- and sex-matched general population. CONCLUSIONS People with youth-onset type 2 diabetes had higher incidence rates of CVD and ESKD than type 1 diabetes. The excess risks in type 2 diabetes were removed after adjusted for cardio-metabolic risk factors.

Abstract
PURPOSE OF REVIEW With the rise in prevalence of youth-onset type 2 diabetes (T2DM), it is imperative to understand the clinical burden of the disease and the socioeconomic burden this disease imposes. We review the most recent data on youth-onset T2DM, including its pathophysiology, complications, and treatment. We also review existing data to determine the socioeconomic burden of youth-onset T2DM. RECENT FINDINGS The incidence of youth-onset T2DM is rising, and significantly accelerated following the COVID-19 pandemic. Youth with T2DM are more frequently from families of racial/ethnic minorities and lower socioeconomic status. Youth-onset T2DM has more rapid disease progression compared to adult-onset type 2 diabetes. It results in earlier and more severe microvascular and macrovascular complications compared to both adult-onset T2DM and youth-onset type 1 diabetes (T1DM). While there is a lack of data describing the socioeconomic cost of youth-onset T2DM, based on extrapolation from analyses of the burden of T2DM in adults and T1DM in youth, we propose that youth-onset T2DM has higher direct and indirect costs than adult-onset T2DM. Youth-onset T2DM presents a significant clinical and socioeconomic burden due to its aggressive presentation and earlier appearance of complications. Additional research is needed regarding the cost of illness in this population.

Abstract
The incidence and prevalence of youth-onset type 2 diabetes mellitus (T2DM) and its complications are increasing worldwide. Youth-onset T2DM has been reported in all racial and ethnic groups, but Indigenous peoples and people of colour are disproportionately affected. People with youth-onset T2DM often have a more aggressive clinical course than those with adult-onset T2DM or those with type 1 diabetes mellitus. Moreover, the available treatment options for children and adolescents with T2DM are more limited than for adult patients. Intermediate complications of youth-onset T2DM, such as increased albuminuria, often develop in late childhood or early adulthood, and end-stage complications, including kidney failure, develop in mid-life. The increasing frequency, earlier onset and greater severity of childhood obesity in the past 50 years together with increasingly sedentary lifestyles and an increasing frequency of intrauterine exposure to diabetes are important drivers of the epidemic of youth-onset T2DM. The particularly high risk of the disease in historically disadvantaged populations suggests an important contribution of social and environmental factors, including limited access to high-quality health care, healthy food choices and opportunities for physical activity as well as exposure to stressors including systemic racism and environmental pollutants. Understanding the mechanisms that underlie the development and aggressive clinical course of youth-onset T2DM is key to identifying successful prevention and management strategies.

Abstract
AIMS This systematic review aims to assess the incidence of chronic kidney disease (CKD), cardiovascular disease (CVD) and mortality in people with type 2 diabetes diagnosed <20 years. METHODS We searched MEDLINE, Embase and Cochrane Library for longitudinal studies published between 1 January 2000 and 31 November 2021. RESULTS Seventeen studies (15 reporting CKD, 3 reporting CVD, 5 reporting mortality) from seven countries of sample size ranging between 96 and 4,141 were eligible. Most studies were conducted in North America and Europe (n = 14). Diabetes duration at enrolment varied from 0 to 8.3 years and follow-up duration from 1 to 12.6 years. The incidence rates (per 1,000 person-year) of albuminuria ranged between 12.4 and 114.8, macroalbuminuria or proteinuria between 10 and 35.0, end-stage kidney disease (ESKD) between 0.4 and 25.0, CVD between 3.7 and 19.5, and mortality between 1.0 and 18.6. The highest incidence rates of albuminuria, ESKD and mortality were recorded in Australian Aboriginal and Pima Indian populations. Youth-onset type 2 diabetes was associated with greater risk of developing CKD compared with type 1 diabetes in most studies. CONCLUSION Studies reporting CVD in youth-onset type 2 diabetes are scarce. Estimated incidence rates of CKD and mortality in youth-onset type 2 diabetes varied across different study populations, potentially higher in indigenous people. Youth with type 2 diabetes are at higher risk of adverse kidney outcomes than their type 1 counterparts. More studies are needed in regions outside of North America and Europe.

Abstract
Under healthy conditions, the pancreas responds to a glucose challenge by releasing insulin. Insulin suppresses lipolysis in adipose tissue, thereby decreasing plasma glycerol concentration, and it regulates plasma glucose concentration through action in muscle and liver. Insulin resistance (IR) occurs when more insulin is required to achieve the same effects, and IR may be tissue-specific. IR emerges during puberty as a result of high concentrations of growth hormone and is worsened by youth-onset obesity. Adipose, liver, and muscle tissue exhibit distinct dose-dependent responses to insulin in multi-phase hyperinsulinemic-euglycemic (HE) clamps, but the HE clamp protocol does not address potential differences in the dynamics of tissue-specific insulin responses. Changes to the dynamics of insulin responses would alter glycemic control in response to a glucose challenge. To investigate the dynamics of insulin acting on adipose tissue, we developed a novel differential-equations based model that describes the coupled dynamics of glycerol concentrations and insulin action during an oral glucose tolerance test in female adolescents with obesity and IR. We compared these dynamics to the dynamics of insulin acting on muscle and liver as assessed with the oral minimal model applied to glucose and insulin data collected under the same protocol. We found that the action of insulin on glycerol peaks approximately 67 min earlier (p < 0.001) and follows the dynamics of plasma insulin more closely compared to insulin action on glucose as assessed by the parameters representing the time constants for insulin action on glucose and glycerol (p < 0.001). These findings suggest that the dynamics of insulin action show tissue-specific differences in our IR adolescent population, with adipose tissue responding to insulin more quickly compared to muscle and liver. Improved understanding of the tissue-specific dynamics of insulin action may provide novel insights into the progression of metabolic disease in patient populations with diverse metabolic phenotypes.

Abstract
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 0.75 mg, or dulaglutide at a dose of 1.5 mg. Participants were then included in a 26-week open-label extension study in which those who had received placebo began receiving dulaglutide at a weekly dose of 0.75 mg. The primary end point was the change from baseline in the glycated hemoglobin level at 26 weeks. Secondary end points included a glycated hemoglobin level of less than 7.0% and changes from baseline in the fasting glucose concentration and BMI. Safety was also assessed. RESULTS A total of 154 participants underwent randomization. At 26 weeks, the mean glycated hemoglobin level had increased in the placebo group (0.6 percentage points) and had decreased in the dulaglutide groups (-0.6 percentage points in the 0.75-mg group and -0.9 percentage points in the 1.5-mg group, P<0.001 for both comparisons vs. placebo). At 26 weeks, a higher percentage of participants in the pooled dulaglutide groups than in the placebo group had a glycated hemoglobin level of less than 7.0% (51% vs. 14%, P<0.001). The fasting glucose concentration increased in the placebo group (17.1 mg per deciliter) and decreased in the pooled dulaglutide groups (-18.9 mg per deciliter, P<0.001), and there were no between-group differences in the change in BMI. The incidence of gastrointestinal adverse events was higher with dulaglutide therapy than with placebo. The safety profile of dulaglutide was consistent with that reported in adults. CONCLUSIONS Treatment with dulaglutide at a once-weekly dose of 0.75 mg or 1.5 mg was superior to placebo in improving glycemic control through 26 weeks among youths with type 2 diabetes who were being treated with or without metformin or basal insulin, without an effect on BMI.

Longitudinal Changes in Arterial Stiffness and Heart Rate Variability in Youth-Onset Type 1 Versus Type 2 Diabetes: The SEARCH for Diabetes in Youth Study. Diabetes Care 2022; 45:1647-1656. [PMID: 35667385 PMCID: PMC9274217 DOI: 10.2337/dc21-2426] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Accepted: 03/02/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE We compared arterial stiffness and heart rate variability (HRV) over time by diabetes type and determined the risk factors associated with worsening arterial stiffness and HRV in young adults with youth-onset diabetes. RESEARCH DESIGN AND METHODS Arterial stiffness (pulse wave velocity, augmentation index) and six indices of heart rate variability were measured twice, 4.5 years apart, among participants with either youth-onset type 1 or type 2 diabetes in the SEARCH for Diabetes in Youth study. Multivariable linear regression models were used to assess risk factors associated with arterial stiffness and HRV at follow-up. RESULTS Of 1,159 participants studied, 949 had type 1 diabetes (mean age 17.1 ± 4.7 years, 60.3% non-Hispanic White, 55% female) and 210 had type 2 diabetes (mean age 22.1 ± 3.5 years, 23.8% non-Hispanic White, 71% female) at initial assessment when diabetes duration was 7.9 years (both groups). Participants with type 2 versus type 1 diabetes had greater arterial stiffness and more abnormalities in HRV at initial and follow-up assessment and a greater change over time (all P < 0.05). Risk factors associated with worse arterial stiffness and HRV at follow-up in both types of diabetes included higher blood pressure, hemoglobin A1c, waist circumference, and triglycerides over time and longer diabetes duration. CONCLUSIONS Arterial stiffness and HRV worsened over time with greater changes among participants with type 2 versus type 1 diabetes and among those with features of the metabolic syndrome. The risk factor profile documents potentially modifiable pathways to prevent or limit cardiovascular complications in young adults with youth-onset diabetes.
