RESUMEN

Importance: The effect of testosterone replacement therapy (TRT) in men with hypogonadism on the risk of progression from prediabetes to diabetes or of inducing glycemic remission in those with diabetes is unknown. Objective: To evaluate the efficacy of TRT in preventing progression from prediabetes to diabetes in men with hypogonadism who had prediabetes and in inducing glycemic remission in those with diabetes. Design, Setting, and Participants: This nested substudy, an intention-to-treat analysis, within a placebo-controlled randomized clinical trial (Testosterone Replacement Therapy for Assessment of Long-Term Vascular Events and Efficacy Response in Hypogonadal Men [TRAVERSE]) was conducted at 316 trial sites in the US. Participants included men aged 45 to 80 years with hypogonadism and prediabetes or diabetes who were enrolled in TRAVERSE between May 23, 2018, and February 1, 2022. Intervention: Participants were randomized 1:1 to receive 1.62% testosterone gel or placebo gel until study completion. Main Outcomes and Measures: The primary end point was the risk of progression from prediabetes to diabetes, analyzed using repeated-measures log-binomial regression. The secondary end point was the risk of glycemic remission (hemoglobin A1c level <6.5% [to convert to proportion of total hemoglobin, multiply by 0.01] or 2 fasting glucose measurements <126 mg/dL [to convert to mmol/L, multiply by 0.0555] without diabetes medication) in men who had diabetes. Results: Of 5204 randomized participants, 1175 with prediabetes (mean [SD] age, 63.8 [8.1] years) and 3880 with diabetes (mean [SD] age, 63.2 [7.8] years) were included in this study. Mean (SD) hemoglobin A1c level in men with prediabetes was 5.8% (0.4%). Risk of progression to diabetes did not differ significantly between testosterone and placebo groups: 4 of 598 (0.7%) vs 8 of 562 (1.4%) at 6 months, 45 of 575 (7.8%) vs 57 of 533 (10.7%) at 12 months, 50 of 494 (10.1%) vs 67 of 460 (14.6%) at 24 months, 46 of 359 (12.8%) vs 52 of 330 (15.8%) at 36 months, and 22 of 164 (13.4%) vs 19 of 121 (15.7%) at 48 months (omnibus test P = .49). The proportions of participants with diabetes who experienced glycemic remission and the changes in glucose and hemoglobin A1c levels were similar in testosterone- and placebo-treated men with prediabetes or diabetes. Conclusions and Relevance: In men with hypogonadism and prediabetes, the incidence of progression from prediabetes to diabetes did not differ significantly between testosterone- and placebo-treated men. Testosterone replacement therapy did not improve glycemic control in men with hypogonadism and prediabetes or diabetes. These findings suggest that TRT alone should not be used as a therapeutic intervention to prevent or treat diabetes in men with hypogonadism.

RESUMEN

Time spent in glycemic target range (time in range [TIR]; plasma glucose 70-180 mg/dL [3.9-10.0 mmol/L]) as a surrogate endpoint for long-term diabetes-related outcomes requires validation. This post hoc analysis investigated the association between TIR, derived from 8-point glucose profiles (derived TIR [dTIR]) at 12 months, and time to cardiovascular or severe hypoglycemic episodes in people with type 2 diabetes in the DEVOTE trial. At 12 months, dTIR was significantly negatively associated with time to first major adverse cardiovascular event (P = 0.0087), severe hypoglycemic episode (P < 0.0001), or microvascular event (P = 0.024). A nonsignificant trend was seen toward association between 12-month hemoglobin A1c (HbA1c) and these outcomes, but this was no longer seen after addition of dTIR to the model. The results support targeting TIR >70% and suggest dTIR could be used in addition to, or in some instances in place of, HbA1c as a clinical biomarker. Trial registration details: ClinicalTrials.gov, NCT01959529.

RESUMEN

OBJECTIVE: While there is evidence that functioning, or ability to perform daily life activities, can be adversely influenced by type 1 diabetes, the impact of acute fluctuations in glucose levels on functioning is poorly understood. RESEARCH DESIGN AND METHODS: Using dynamic structural equation modeling, we examined whether overnight glucose (coefficient of variation[CV], percent time <70 mg/dL, percent time >250 mg/dL) predicted seven next-day functioning outcomes (mobile cognitive tasks, accelerometry-derived physical activity, self-reported activity participation) in adults with type 1 diabetes. We examined mediation, moderation, and whether short-term relationships were predictive of global patient-reported outcomes. RESULTS: Overall next-day functioning was significantly predicted from overnight CV (P = 0.017) and percent time >250 mg/dL (P = 0.037). Pairwise tests indicate that higher CV is associated with poorer sustained attention (P = 0.028) and lower engagement in demanding activities (P = 0.028), time <70 mg/dL is associated with poorer sustained attention (P = 0.007), and time >250 mg/dL is associated with more sedentary time (P = 0.024). The impact of CV on sustained attention is partially mediated by sleep fragmentation. Individual differences in the effect of overnight time <70 mg/dL on sustained attention predict global illness intrusiveness (P = 0.016) and diabetes-related quality of life (P = 0.036). CONCLUSIONS: Overnight glucose predicts problems with objective and self-reported next-day functioning and can adversely impact global patient-reported outcomes. These findings across diverse outcomes highlight the wide-ranging effects of glucose fluctuations on functioning in adults with type 1 diabetes.

RESUMEN

BACKGROUND: The Glycemia Risk Index (GRI) was introduced as a single value derived from the ambulatory glucose profile that identifies patients who need attention. This study describes participants in each of the five GRI zones and examines the percentage of variation in GRI scores that is explained by sociodemographic and clinical variables among diverse adults with type 1 diabetes. METHODS: A total of 159 participants provided blinded continuous glucose monitoring (CGM) data over 14 days (mean age [SD] = 41.4 [14.5] years; female = 54.1%, Hispanic = 41.5%). Glycemia Risk Index zones were compared on CGM, sociodemographic, and clinical variables. Shapley value analysis examined the percentage of variation in GRI scores explained by different variables. Receiver operating characteristic curves examined GRI cutoffs for those more likely to have experienced ketoacidosis or severe hypoglycemia. RESULTS: Mean glucose and variability, time in range, and percentage of time in high, and very high, glucose ranges differed across the five GRI zones (P values < .001). Multiple sociodemographic indices also differed across zones, including education level, race/ethnicity, age, and insurance status. Sociodemographic and clinical variables collectively explained 62.2% of variance in GRI scores. A GRI score ≥84.5 reflected greater likelihood of ketoacidosis (area under the curve [AUC] = 0.848), and scores ≥58.2 reflected greater likelihood of severe hypoglycemia (AUC = 0.729) over the previous six months. CONCLUSIONS: Results support the use of the GRI, with GRI zones identifying those in need of clinical attention. Findings highlight the need to address health inequities. Treatment differences associated with the GRI also suggest behavioral and clinical interventions including starting individuals on CGM or automated insulin delivery systems.

RESUMEN

OBJECTIVE: Automated insulin delivery (AID) has rarely been studied in adults with type 2 diabetes. We tested the feasibility of using AID for type 2 diabetes with the Omnipod 5 System in a multicenter outpatient trial. RESEARCH DESIGN AND METHODS: Participants previously were using either basal-only or basal-bolus insulin injections, with or without the use of a continuous glucose monitor (CGM), and had a baseline HbA1c ≥8% (≥64 mmol/mol). Participants completed 2 weeks of CGM sensor data collection (blinded for those not previously using CGM) with their standard therapy (ST), then transitioned to 8 weeks of AID. Participants who previously used basal-only injections used the AID system in manual mode for 2 weeks before starting AID. Antihyperglycemic agents were continued at clinician discretion. Primary safety outcomes were percentage of time with sensor glucose ≥250 mg/dL and <54 mg/dL during AID. Additional outcomes included HbA1c and time in target range (TIR) (70-180 mg/dL). RESULTS: Participants (N = 24) had a mean (± SD) age of 61 ± 8 years, baseline HbA1c of 9.4% ± 0.9% (79 ± 10 mmol/mol), and diabetes duration of 19 ± 9 years. Percentage of time with sensor glucose ≥250 mg/dL decreased with AID by 16.9% ± 16.2% (P < 0.0001), whereas percentage of time at <54 mg/dL remained low during both ST and AID (median [interquartile range] 0.0% [0.00%, 0.06%] vs. 0.00% [0.00%, 0.03%]; P = 0.4543). HbA1c (± SD) decreased by 1.3% ± 0.7% (14 ± 8 mmol/mol; P < 0.0001) and TIR increased by 21.9% ± 15.2% (P < 0.0001) without a significant change in total daily insulin or BMI with AID. CONCLUSIONS: Findings from this feasibility trial of AID in adults with type 2 diabetes with suboptimal glycemic outcomes justify further evaluation of this technology in this population.

RESUMEN

AIM: To assess the efficacy and safety of sotagliflozin, a dual inhibitor of sodium-glucose co-transporters 1 and 2, in adults with type 2 diabetes (T2D) and stage 3 chronic kidney disease (CKD3). MATERIALS AND METHODS: This phase 3, randomized, placebo-controlled trial evaluated sotagliflozin 200 and 400 mg in 787 patients with T2D and an estimated glomerular filtration rate of 30-59 ml/min/1.73m2 . The primary objective was superiority of week 26 HbA1c reductions with sotagliflozin versus placebo. Secondary endpoints included changes in other glycaemic and renal endpoints overall and in CKD3 subgroups. RESULTS: At 26 weeks, the placebo-adjusted mean change in HbA1c (from a baseline of 8.3% ± 1.0%) was -0.1% (95% CI: -0.2% to 0.05%; P = .2095) and -0.2% (-0.4% to -0.09%; P = .0021) in the sotagliflozin 200 and 400 mg groups, respectively. Significant reductions in fasting plasma glucose and body weight, but not systolic blood pressure, were observed. Among patients with at least A2 albuminuria at week 26, the urine albumin-creatinine ratio (UACR) was reduced with both sotagliflozin doses relative to placebo. At week 52, UACR was reduced with sotagliflozin 200 mg in the CKD3B group. Adverse events (AEs), including serious AEs, were similar between the treatment groups. CONCLUSIONS: After 26 weeks, HbA1c was significantly reduced with sotagliflozin 400 but not 200 mg compared with placebo in this CKD3 cohort. UACR in patients with at least A2 albuminuria was reduced with each of the two doses at 26 weeks, but changes were not sustained at week 52. The safety findings were consistent with previous reports (NCT03242252).

RESUMEN

Analog insulins, insulin pumps, and continuous glucose monitors (CGM) have revolutionized type 1 diabetes (T1D) treatment over the last 50 years. Nevertheless, less than 20% of patients in the United States reach guideline-based HbA1c targets. The dysfunctional delivery of U.S. health care has further worsened glycemic outcomes among structurally disadvantaged groups such as non-Hispanic Black and low-income populations. Administrative complexities resulting from mixed insurance coverage and delivery systems, incongruity between effective policies and reimbursement, structural racism, and implicit biases have led to high diabetes care-related costs, provider scarcity and burnout, and patient diabetes distress. The Extension for Community Healthcare Outcomes (ECHO) Diabetes tele-education outreach model was created to increase self-efficacy among primary care providers through a combination of weekly didactic sessions led by a team of diabetes experts and access to community-based peer coaches. As an evolution of ECHO Diabetes, Blue Circle Health has been established as a philanthropically funded health care delivery system, using a whole-person, individualized approach to T1D care for adults living in underserved communities. The program will provide direct-to-patient telehealth services, including diabetes education, management, and related psychological care regardless of ability to pay. Community-based diabetes support coaches will serve as the primary point of contact, or guide on the "Blue Circle Health Member Journey." Access to needed insulins, supplies, and CGMs will be provided at no cost to the individual. Through a continuous learning and improvement model, a person-centered, equitable, accessible, and effective health care delivery model will be built for people living with T1D.

RESUMEN

Regular physical activity improves cardiometabolic and musculoskeletal health, helps with weight management, improves cognitive and psychosocial functioning, and is associated with reduced mortality related to cancer and diabetes mellitus. However, turnover rates of glucose in the blood increase dramatically during exercise, which often results in either hypoglycaemia or hyperglycaemia as well as increased glycaemic variability in individuals with type 1 diabetes mellitus (T1DM). A complex neuroendocrine response to an acute exercise session helps to maintain circulating levels of glucose in a fairly tight range in healthy individuals, while several abnormal physiological processes and limitations of insulin therapy limit the capacity of people with T1DM to exercise in a normoglycaemic state. Knowledge of the acute and chronic effects of exercise and regular physical activity is critical for the formulation of clinical strategies for the management of insulin and nutrition for active patients with T1DM. Emerging diabetes-related technologies, such as continuous glucose monitors, automated insulin delivery systems and the administration of solubilized glucagon, are demonstrating efficacy for preserving glucose homeostasis during and after exercise in this population of patients. This Review highlights the beneficial effects of regular exercise and details the complex endocrine and metabolic responses to different types of exercise for adults with T1DM. An overview of basic clinical strategies for the preservation of glucose homeostasis using emerging technologies is also provided.

RESUMEN

BACKGROUND: A composite metric for the quality of glycemia from continuous glucose monitor (CGM) tracings could be useful for assisting with basic clinical interpretation of CGM data. METHODS: We assembled a data set of 14-day CGM tracings from 225 insulin-treated adults with diabetes. Using a balanced incomplete block design, 330 clinicians who were highly experienced with CGM analysis and interpretation ranked the CGM tracings from best to worst quality of glycemia. We used principal component analysis and multiple regressions to develop a model to predict the clinician ranking based on seven standard metrics in an Ambulatory Glucose Profile: very low-glucose and low-glucose hypoglycemia; very high-glucose and high-glucose hyperglycemia; time in range; mean glucose; and coefficient of variation. RESULTS: The analysis showed that clinician rankings depend on two components, one related to hypoglycemia that gives more weight to very low-glucose than to low-glucose and the other related to hyperglycemia that likewise gives greater weight to very high-glucose than to high-glucose. These two components should be calculated and displayed separately, but they can also be combined into a single Glycemia Risk Index (GRI) that corresponds closely to the clinician rankings of the overall quality of glycemia (r = 0.95). The GRI can be displayed graphically on a GRI Grid with the hypoglycemia component on the horizontal axis and the hyperglycemia component on the vertical axis. Diagonal lines divide the graph into five zones (quintiles) corresponding to the best (0th to 20th percentile) to worst (81st to 100th percentile) overall quality of glycemia. The GRI Grid enables users to track sequential changes within an individual over time and compare groups of individuals. CONCLUSION: The GRI is a single-number summary of the quality of glycemia. Its hypoglycemia and hyperglycemia components provide actionable scores and a graphical display (the GRI Grid) that can be used by clinicians and researchers to determine the glycemic effects of prescribed and investigational treatments.

RESUMEN

A technological solution for the management of diabetes in people who require intensive insulin therapy has been sought for decades. The last 10 years have seen substantial growth in devices that can be integrated into clinical care. Driven by the availability of reliable systems for continuous glucose monitoring, we have entered an era in which insulin delivery through insulin pumps can be modulated based on sensor glucose data. Over the past few years, regulatory approval of the first automated insulin delivery (AID) systems has been granted, and these systems have been adopted into clinical care. Additionally, a community of people living with type 1 diabetes has created its own systems using a do-it-yourself approach by using products commercialised for independent use. With several AID systems in development, some of which are anticipated to be granted regulatory approval in the near future, the joint Diabetes Technology Working Group of the European Association for the Study of Diabetes and the American Diabetes Association has created this consensus report. We provide a review of the current landscape of AID systems, with a particular focus on their safety. We conclude with a series of recommended targeted actions. This is the fourth in a series of reports issued by this working group. The working group was jointly commissioned by the executives of both organisations to write the first statement on insulin pumps, which was published in 2015. The original authoring group was comprised by three nominated members of the American Diabetes Association and three nominated members of the European Association for the Study of Diabetes. Additional authors have been added to the group to increase diversity and range of expertise. Each organisation has provided a similar internal review process for each manuscript prior to submission for editorial review by the two journals. Harmonisation of editorial and substantial modifications has occurred at both levels. The members of the group have selected the subject of each statement and submitted the selection to both organisations for confirmation.

RESUMEN

Disparities and inequities exist for individuals with diabetes in marginalized communities of color, especially among people with low socioeconomic status. Although these barriers are apparent, only a few care models have been designed for and examined in racially and ethnically diverse individuals. This article reviews models that have been developed and examined in a variety of different populations and focuses on how to implement elements from these programs in clinical practice. Health equity-promoting ideas and approaches that can be applied throughout the life span (children to seniors) are also included. As diabetes health care providers, researchers, educators, policymakers, and advocates, we must now combine our efforts and focus on historically excluded populations to bridge the gap to essential diabetes care.

RESUMEN

Objective: To evaluate glycemic outcomes in the Wireless Innovation for Seniors with Diabetes Mellitus (WISDM) randomized clinical trial (RCT) participants during an observational extension phase. Research Design and Methods: WISDM RCT was a 26-week RCT comparing continuous glucose monitoring (CGM) with blood glucose monitoring (BGM) in 203 adults aged ≥60 years with type 1 diabetes. Of the 198 participants who completed the RCT, 100 (98%) CGM group participants continued CGM (CGM-CGM cohort) and 94 (98%) BGM group participants initiated CGM (BGM-CGM cohort) for an additional 26 weeks. Results: CGM was used a median of >90% of the time at 52 weeks in both cohorts. In the CGM-CGM cohort, median time <70 mg/dL decreased from 5.0% at baseline to 2.6% at 26 weeks and remained stable with a median of 2.8% at 52 weeks (P < 0.001 baseline to 52 weeks). Participants spent more time in range 70-180 mg/dL (TIR) (mean 56% vs. 64%; P < 0.001) and had lower hemoglobin A1c (HbA1c) (mean 7.6% [59 mmol/mol] vs. 7.4% [57 mmol/mol]; P = 0.01) from baseline to 52 weeks. In BGM-CGM, from 26 to 52 weeks median time <70 mg/dL decreased from 3.9% to 1.9% (P < 0.001), TIR increased from 56% to 60% (P = 0.006) and HbA1c decreased from 7.5% (58 mmol/mol) to 7.3% (57 mmol/mol) (P = 0.025). In BGM-CGM, a severe hypoglycemic event was reported for nine participants while using BGM during the RCT and for two participants during the extension phase with CGM (P = 0.02). Conclusions: CGM use reduced hypoglycemia without increasing hyperglycemia in older adults with type 1 diabetes. These data provide further evidence for fully integrating CGM into clinical practice.

RESUMEN

BACKGROUND/OBJECTIVES: Routine use of vitamin D supplements has increased substantially in the United States. However, the safety and tolerability of long-term use of high-dose vitamin D are not known. We assessed the safety and tolerability of high-dose, daily vitamin D3 in the vitamin D and type 2 diabetes (D2d) study. SUBJECTS/METHODS: In total, 2423 overweight/obese persons with prediabetes were randomized in a double-blind manner to either 4000 IU of vitamin D3 (the tolerable upper intake level for adults by the National Academy of Medicine) taken daily or matching placebo. All participants were included in this analysis. Incident adverse events (AE) were ascertained 4 times a year at in-person visits (twice a year) and interim remote encounters (twice a year) and were defined as untoward or unfavorable medical occurrences. Serious adverse events (SAE) included death, life-threatening events, and hospitalizations. RESULTS: A total of 8304 AEs occurred during 3 years of follow-up and were less frequent in the vitamin D group compared to placebo (Incidence Rate Ratio [IRR] = 0.94; 95% Confidence Interval (CI) 0.90, 0.98). The overall frequency of protocol-specified AEs of interest, which included nephrolithiasis, hypercalcemia, hypercalciuria, or low estimated glomerular filtration rate, was low and did not differ by group. There were no significant between-group differences in total SAEs (IRR = 0.96 (0.81, 1.14)). CONCLUSION: Vitamin D3 supplementation at 4000 IU per day was safe and well tolerated among overweight/obese participants at high risk for diabetes who were appropriately monitored for safety. In this population, this dose of vitamin D3 did not increase risk of AEs or SAEs, including those previously associated with vitamin D such as hypercalcemia, hypercalciuria, or nephrolithiasis. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT01942694, prospectively registered September 16, 2013.

RESUMEN

OBJECTIVES: To assess risk factors and incidence of diabetes complications in women with type 1 diabetes (T1D) based on parity. RESEARCH DESIGN/METHODS: Data were collected from women (16-40 years old) in the T1D Exchange completing pregnancy/childbirth questionnaires during 2011-2013 and 2016-2018. Incidence of risk factors and diabetes complications were compared between women with a first pregnancy at/within 1-year of enrollment (n = 28) and never pregnant women by year 5 (n = 469). RESULTS: There was a trend for lower HbA1c (adjusted p = .14) and higher rates of overweight/obesity, triglyceride/HDL > 2, log (triglyercide/HDL), and hypertension among parous women compared with nulliparous women. There were no significant differences in rates of advanced nephropathy, albuminuria or cardiovascular disease. CONCLUSIONS: Four-5 years after delivery, parous women with T1D tended to have lower HbA1c levels despite higher body mass indices and more frequent adverse lipid profiles and hypertension compared with nulliparous women. Further studies based on these trends are warranted.

RESUMEN

Background: Health care disparities in the use of diabetes devices are particularly prevalent, especially given the high levels of health literacy and numeracy needed to understand their use. Methods: To reduce this gap, we created lower literacy, English and Spanish multicultural guides for insulin pen and pump use. Focus groups provided input, nonbranded illustrations were designed, and simplified text was developed. The guides were implemented in our clinic for underresourced individuals in East Los Angeles, California. Subjects given the low literacy guides participated in guide-driven individual and group education, and measures were administered at baseline, 6 and 12 months. Results: Sixty-three adults with type 1 diabetes (T1D) were included, and 43 (68%) completed all 12 months of the study. Initial HbA1c was 9.2 ± 1.97 (standard deviation) with no change over the study course (12-month A1C = 9.3 ± 1.92). However, participants showed significantly reduced psychological distress due to diabetes, increased diabetes knowledge, improved self-report of health, and a trend toward reduced depression. There was also a reduction in rates of diabetic ketoacidosis (DKA). There was no change in rates of hypoglycemia, although there was an increase in fear of hypoglycemia. Conclusions: Appropriately targeted teaching guides can be used to improve various patient-reported outcomes in people with T1D, specifically, overall self-report of health, distress due to diabetes, and diabetes knowledge. Targeted teaching guides also achieved improvements in rates of DKA in T1D. While these results are encouraging, more work is needed to make a significant impact on glycemic control. Clinical Trials registration number: NCT04550585.

RESUMEN

The American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) convened a writing group to develop a consensus statement on the management of type 1 diabetes in adults. The writing group has considered the rapid development of new treatments and technologies and addressed the following topics: diagnosis, aims of management, schedule of care, diabetes self-management education and support, glucose monitoring, insulin therapy, hypoglycemia, behavioral considerations, psychosocial care, diabetic ketoacidosis, pancreas and islet transplantation, adjunctive therapies, special populations, inpatient management, and future perspectives. Although we discuss the schedule for follow-up examinations and testing, we have not included the evaluation and treatment of the chronic microvascular and macrovascular complications of diabetes as these are well-reviewed and discussed elsewhere. The writing group was aware of both national and international guidance on type 1 diabetes and did not seek to replicate this but rather aimed to highlight the major areas that health care professionals should consider when managing adults with type 1 diabetes. Though evidence-based where possible, the recommendations in the report represent the consensus opinion of the authors.
