- Aims: To update and extend a previous cross-sectional international comparison of glycaemic control in people with type 1 diabetes. Methods: Data were obtained for 520,392 children and adults with type 1 diabetes from 17 population and five clinic-based data sources in countries or regions between 2016 and 2020. Median HbA1c(IQR) and proportions of individuals with HbA1c < 58mmol/mol (<7.5%), 58–74mmol/mol (7.5–8.9%) and ≥75mmol/mol (≥9.0%) were compared between populations for individuals aged <15, 15–24 and ≥25 years. Logistic regression was used to estimate the odds ratio (OR) of HbA1c < 58mmol/mol (<7.5%) relative to ≥58mmol/mol (≥7.5%), stratified and adjusted for sex, age and data source. Where possible, changes in the proportion of individuals in each HbA1c category compared to previous estimates were calculated. Results: Median HbA1c varied from 55 to 79mmol/mol (7.2 to 9.4%) across data sources and age groups so a pooled estimate was deemed inappropriate. OR (95% CI) for HbA1c< 58mmol/mol (<7.5%) were 0.91 (0.90–0.92) for women compared to men, 1.68 (1.65–1.71) for people aged <15years and 0.81 (0.79–0.82) aged15–24years compared to those aged ≥25years. Differences between populations persisted after adjusting for sex, age and data source. In general, compared to our previous analysis, the proportion of people with an HbA1c<58mmol/l (<7.5%) increased and proportions of people with HbA1c≥ 75mmol/mol (≥9.0%) decreased. Conclusions: Glycaemic control of type 1 diabetes continues to vary substantially between age groups and data sources. While some improvement over time has been observed, glycaemic control remains sub-optimal for most people with Type 1 diabetes.

- Objective: Co-aggregation of autoimmune diseases is common, suggesting pa rtly shared etiologies. Genetic factors are believed to be important, but objective measures of environ mental vs heritable influences on co-aggregation are absent. With a novel approach to twin studies, we aimed at esti mating heritability and genetic overlap in seven organspecific autoimmune diseases. Design: Prospective twin cohort study. Methods: We used a cohort of 110 814 twins to examine co-aggregation an d heritability of Hashimoto's thyroiditis, atrophic gastritis, celiac disease, Graves' disease, type 1 dia betes, vitiligo and Addison's disease. Hazard ratios (HR) were calculated for twins developing the same or different disea se as compared to their co-twin. The differences between monozygotic and dizygotic twin pairs were used to estim ate the genetic influence on co- aggregation. Heritability for individual disorders was calculated using stru ctural equational modeling adjusting for censoring and truncation of data. Results: Co-aggregation was more pronounced in monozygotic twins (media n HR: 3.2, range: 2.2-9.2) than in dizygotic twins (median HR: 2.4, range: 1.1-10.0). Heritability was moder ate for atrophic gastritis (0.38, 95% CI: 0.23-0.53) but high for all other diseases, ranging from 0.60 (95% CI: 0.49-0. 71) for Graves' disease to 0.97 (95% CI: 0.91- 1.00) for Addison's disease. Conclusions: Overall, co-aggregation was more pronounced in monozygotic tha n in dizygotic twins, suggesting that disease overlap is largely attributable to genetic factors. Co- aggregation was common, and twins faced up to a ten-fold risk of developing diseases not present in their co-twin. Our r esults validate and refine previous heritability estimates based on smaller twin cohorts.

- Introduction Renal complications are both a marker of previous suboptimal glycaemic control and a major risk factor for cardiovascular disease in persons with type 1 diabetes (T1D). The aim of the study was to evaluate the prevalence of renal complications in persons with T1D in four geographical regions. Methods Nationwide registry data from Austria/Germany, Sweden and the US were used to estimate the prevalence of renal complications from January 2016 until September 2018. Chronic kidney disease (CKD) and albuminuria in the study population and each registry were analysed by diabetes duration. Risk factors for renal complications were described by registry. Results In the total cohort of 78.926 adults with T1D, mean age was 44.4 +/- 18.43 years and mean diabetes duration was 21.6 +/- 22 years. Mean estimated glomerular filtration rate (eGFR) was 94.0 +/- 31.45 ml/min, 13.0% had microalbuminuria and 3.9% had macroalbuminuria. Mean age, diabetes duration, use of insulin pumps and continuous glucose monitoring, as well as presence of albuminuria, varied between registries. Albuminuria was present in approximately 10% of persons with diabetes duration < 20 years and impaired renal function (eGFR < 60 ml/min) was present in 17%. In persons with diabetes duration > 40 years, approximately one-third had albuminuria and 25% had impaired renal function. Conclusions This analysis used three nationwide registries of persons with T1D. Despite recent use of more effective diabetes therapies, a substantial proportion of persons with T1D have renal complications at < 20 years after diagnosis. Efficient glucose-lowering and renal-protective strategies are needed in persons with T1D.

- Aims To explore persistence with insulin degludec/liraglutide (IDegLira) treatment, clinical characteristics and concomitant medications in a large population of patients in clinical practice. Methods This was an observational study in patients with type 2 diabetes (n = 2432) who initiated IDegLira between 26 May 2015 and 31 December 2017. Data were obtained from Swedish nationwide registers and linked on an individual level using unique Swedish personal identifiers. Dose calculations were made for patients with >= 180 days between the first and last collections of IDegLira prescription. Changes in clinical parameters were evaluated as change from the last observation during 12 months prior to the initiation date until +/- 90 days from the last collection of IDegLira. Results Pre-index regimens (index date being the date of filling the first prescription of IDegLira) included: multiple daily insulin injections (45.1%); insulin and glucagon-like peptide-1 receptor agonist (GLP-1 RA) (19.7%); long-acting insulins (11.8%); non-injectable therapy only (11.4%); GLP-1 RA only (9.8%); and no collection of diabetes medication during the 6-month pre-index period (2.3%). The majority of patients (94 and 84%) were persistent with IDegLira at 6 and 12 months, respectively. The most commonly used concomitant medication was metformin (69.4%). Mean daily dose was 33 dose steps. Overall, there was a mean decrease in HbA1c (approx. 10 mmol/mol [1%]) and body weight (- 1.1 kg). Improvements in HbA1c were observed regardless of pre-index treatment. Conclusion After 12 months, 84% of patients were persistent on IDegLira, with improved glycaemic control and reductions in body weight.

- Aims/hypothesis We aimed to report current rates of CVD in type 1 diabetes and to develop a CVD risk prediction tool for type 1 diabetes. Methods A cohort of 27,527 people with type 1 diabetes without prior CVD was derived from the national register in Scotland. Incident CVD events during 199,552 person-years of follow-up were ascertained using hospital admissions and death registers. A Poisson regression model of CVD was developed and then validated in the Swedish National Diabetes Register (n = 33,183). We compared the percentage with a high 10 year CVD risk (i.e., >= 10%) using the model with the percentage eligible for statins using current guidelines by age. Results The age-standardised rate of CVD per 100,000 person-years was 4070 and 3429 in men and women, respectively, with type 1 diabetes in Scotland, and 4014 and 3956 in men and women in Sweden. The final model was well calibrated (Hosmer- Lemeshow test p > 0.05) and included a further 22 terms over a base model of age, sex and diabetes duration (C statistic 0.82; 95% CI 0.81, 0.83). The model increased the base model C statistic foam 0.66 to 0.80, from 0.60 to 0.75 and from 0.62 to 0.68 in those aged <40, 40-59 and >= 60 years, respectively (alp values <0.005). The model required minimal calibration in Sweden and had a C statistic of 0.85. Under current guidelines, >90% of those aged 20-39 years and 100% of those >= 40 years with type 1 diabetes were eligible for statins, but it was not until age 65 upwards that 100% had a modelled risk of CVD >= 10% in 10 years. Conclusions/interpretation A prediction tool such as that developed here can provide individualised risk predictions. This 10 year CVD risk prediction tool could facilitate patient discussions regarding appropriate statin prescribing. Apart from 10 year risk, such discussions may also consider longer-term CVD risk, the potential for greater benefits from early vs later statin intervention. the potential impact on quality of life of an early CVD event and evidence on safety, all of which could influence treatment decisions, particularly in younger people with type 1 diabetes.

- OBJECTIVE To develop a patient-level simulation model for predicting lifetime health outcomes of patients with type 1 diabetes and as a tool for economic evaluation of type 1 diabetes treatment based on data from a large, longitudinal cohort. RESEARCH DESIGN AND METHODS Data for model development were obtained from the Swedish National Diabetes Register. We derived parametric proportional hazards models predicting the absolute risk of diabetes complications and death based on a wide range of clinical variables and history of complications. We used linear regression models to predict risk factor progression. Internal validation was performed, estimates of life expectancies for different age-sex strata were computed, and the impact of key risk factors on life expectancy was assessed. RESULTS The study population consisted of 27,841 patients with type 1 diabetes with a mean duration of follow-up of 7 years. Internal validation showed good agreement between the predicted and observed cumulative incidence of death and 10 complications. Simulated life expectancy was similar to 13 years lower than that of the sex- and age-matched general population, and patients with type 1 diabetes could expect to live with one or more complications for similar to 40% of their remaining life. Sensitivity analysis showed the importance of preventing renal dysfunction, hypoglycemia, and hyperglycemia as well as lowering HbA(1c)in reducing the risk of complications and death. CONCLUSIONS Our model was able to simulate risk factor progression and event histories that closely match the observed outcomes and to project events occurring over patients' lifetimes. The model can serve as a tool to estimate the impact of changing clinical risk factors on health outcomes to inform economic evaluations of interventions in type 1 diabetes.

- Aims: This study assessed hemoglobin A1c (HbA1c) across the lifespan in people with type 1 diabetes (T1D) in Germany/Austria, Sweden, and the United States between 2011 and 2017 to ascertain temporal and age-related trends. Methods: Data from the Diabetes-Patienten-Verlaufsdokumentation (DPV) (n = 25,651 in 2011, n = 29,442 in 2017); Swedish Pediatric Diabetes Quality Registry (SWEDIABKIDS)/National Diabetes Register (NDR), (n = 44,474 in 2011, n = 53,690 in 2017); and T1D Exchange (n = 16,198 in 2011, n = 17,087 in 2017) registries were analyzed by linear regression to compare mean HbA1c overall and by age group. Results: Controlling for age, sex, and T1D duration, HbA1c increased in the United States between 2011 and 2017, decreased in Sweden, and did not change in Germany/Austria. Controlling for sex and T1D duration, mean HbA1c decreased between 2011 and 2017 in all age cohorts in Sweden (P < 0.001). In the United States, HbA1c stayed the same for participants <6 years and 45 to <65 years and increased in all other age groups (P < 0.05). In Germany/Austria, HbA1c stayed the same for participants <6 to <13 years and 18 to <25 years; decreased for participants ages 13 to <18 years (P < 0.01); and increased for participants >= 25 years (P < 0.05). Conclusions: The comparison of international trends in HbA1c makes it possible to identify differences, explore underlying causes, and share quality improvement processes. National quality improvement initiatives are well accepted in Europe but have yet to be implemented systematically in the United States. However, disparities created by the lack of universal access to health care coverage, unequal access to diabetes technologies (e.g., continuous glucose monitoring) regardless of insurance status, and high out-of-pocket cost for the underinsured ultimately limit the potential of quality improvement initiatives.

- OBJECTIVE To investigate the nature of the relationship between HbA1c and sepsis among individuals with type 2 diabetes, and to assess the association between sepsis and all-cause mortality in such patients. RESEARCH DESIGN AND METHODS We included 502,871 individuals with type 2 diabetes recorded in the Swedish National Diabetes Register and used multivariable Cox regression and restricted cubic spline analyses to assess the association between time-updated HbA1c values and sepsis occurrence between 1 January 2005 and 31 December 2015. The association between sepsis and death was examined using multivariable Cox regression analysis. RESULTS Overall, 14,534 (2.9%) patients developed sepsis during the study period. On multivariable Cox regression analysis, compared with an HbA1c of 48–52 mmol/mol (6.5–6.9%), the adjusted hazard ratio for sepsis was 1.15 (95% CI 1.07–1.24) for HbA1c <43 mmol/mol (6.1%), 0.93 (0.87–0.99) for HbA1c 53–62 mmol/mol (7.0–7.8%), 1.05 (0.97–1.13) for HbA1c 63–72 mmol/mol (7.9–8.7%), 1.14 (1.04–1.25) for HbA1c 73–82 mmol/mol (8.8–9.7%), and 1.52 (1.37–1.68) for HbA1c >82 mmol/mol (9.7%). In the cubic spline model, a reduction of the adjusted risk was observed within the lower HbA1c range until 53 mmol/mol (7.0%), with a hazard ratio of 0.78 (0.73–0.82) per SD; it increased thereafter (P for nonlinearity <0.001). As compared with patients without sepsis, the adjusted hazard ratio for death among patients with sepsis was 4.16 (4.03–4.30). CONCLUSIONS In a nationwide cohort of individuals with type 2 diabetes, we found a U-shaped association between HbA1c and sepsis and a fourfold increased risk of death among those developing sepsis. © 2021 by the American Diabetes Association.

- IntroductionWere the participants of the EMPA-REG OUTCOME trial representative of patients receiving empagliflozin in clinical practice? The aim of the present study was to examine the prevalence of cardiovascular disease (CVD) in type 2 diabetes patients starting empagliflozin treatment in routine clinical practice in Sweden.MethodsWe used nationwide data from the Swedish National Diabetes Register (NDR), the Swedish Prescribed Drug Register, and the Swedish National Patient Register to provide clinical characteristics and ongoing treatments.ResultsThe total study cohort included 460,558 patients, of whom 130,508 (28.3%) had a history of CVD. The number of patients starting empagliflozin during the study period was 16,985. Among these, 1952 (11.5%) had a history of CVD. The patients starting empagliflozin were younger than the total cohort and were more likely to have retinopathy despite having a similar duration of diabetes to the overall cohort. They also exhibited higher BMI, HbA1c, and eGFR, and were more likely to be treated with insulin and lipid-lowering and blood-pressure-lowering medications. The patients with CVD who were starting empagliflozin were slightly older and had been diabetic for slightly longer than the patients without CVD who were starting empagliflozin, but they also had lower eGFR. Among the patients with CVD who were starting empagliflozin, 87% had coronary heart disease, 8% had suffered a stroke, 13% had peripheral artery disease, 16% had atrial fibrillation, and 20% had congestive heart failure.ConclusionThe prevalence of CVD in patients with type 2 diabetes in clinical practice in Sweden was 28.3% during the study period, and it was 11.5% in the patients starting empagliflozin treatment. Patients of the latter cohort were, however, younger, more obese, and more likely to have unsatisfactory glycemic control, requiring additional treatment. Overall, a large proportion of type 2 diabetes patients should be considered at high cardiovascular risk.FundingBoehringer Ingelheim AB, Sweden.
