Hospitalization for hypoglycaemia in people with diabetes in Denmark, 1997-2017: Time trends in incidence and HbA_1c and glucose-lowering drug use before and after hypoglycaemia.

ABSTRACT:

Objective

To assess incidence trends of first hospitalization for hypoglycaemia in Denmark and to examine HbA_1c levels and glucose-lowering drug use before and after hospitalization among individuals with type 1 or type 2 diabetes.

Research design and methods

We performed a population-based study linking diagnosis, prescription and laboratory data. Standardized incidence of first hospitalization for hypoglycaemia in Denmark was assessed for each calendar year 1997-2017. HbA1c and glucose-lowering drug use was compared with age- and sex-matched diabetes comparisons without hospitalization for hypoglycaemia.

Results

The annual age- and sex-standardized incidence rate of first hospitalization for hypoglycaemia per 100,000 person-years increased during 1997-2003 (from 17.7 to 30.3 per 100,000 person-years), remained stable until 2010 (30.4) and gradually declined until 2017 (22.0). During this period, we identified 3,479 people with type 1 diabetes and 15,329 people with type 2 diabetes experiencing first hospitalization for hypoglycaemia. Both diabetes groups experienced a mean HbA1c decrease of ~12%-15% in the months preceding first hospitalization, followed by a gradually increasing HbA1c afterwards. People with type 1 diabetes and hospitalization used similar insulin therapies as those without hospitalization. People with type 2 diabetes and hospitalization more often received insulin (55%) than comparisons (45%), and 45% discontinued insulin or stopped all glucose-lowering therapy after first hospitalization.

Conclusions

Incidence of hospitalizations for hypoglycaemia has declined by one fourth the last decade in the Danish population. A HbA1c decrease precedes first hospitalization for hypoglycaemia in individuals with diabetes, and profound changes in glucose-lowering drug therapy for type 2 diabetes occur after hospitalization.

Project description:IntroductionThe efficacy and safety of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, were investigated in patients with type 2 diabetes (T2D) in the Peptide InnOvatioN for Early diabEtes tReatment (PIONEER) programme. The current post-hoc exploratory subgroup analyses evaluated outcomes by background medication and insulin regimen subgroups.MethodsData from patients in the PIONEER 3-5, 7 and 8 trials receiving once-daily oral semaglutide (14 mg/flexibly dosed) or a comparator (placebo, sitagliptin 100 mg or liraglutide 1.8 mg) were analysed for efficacy (glycated haemoglobin [HbA1c] and body weight changes from baseline to planned end of treatment) and safety outcomes. Patients were grouped according to background medication (metformin, sulphonylurea, thiazolidinedione, sodium-glucose cotransporter-2 inhibitor, insulin, or combinations thereof). Efficacy outcomes were analysed using the trial product estimand (which assumes that patients remained on the trial product without rescue medication use). A separate analysis by background insulin regimen (basal, premixed or basal-bolus) was done for PIONEER 8 using the treatment policy estimand (regardless of trial product discontinuation or rescue medication use). Safety outcomes were analysed descriptively for all patients.ResultsIn total, 2836 patients receiving oral semaglutide 14 mg/flexibly dosed or comparators were included. Baseline characteristics were generally similar across background medication subgroups within each trial. Diabetes duration tended to be longer in patients receiving more background medications. Greater HbA1c and body weight reductions were seen across background medication subgroups with oral semaglutide (changes from baseline: - 1.0 to - 1.5% and - 2.2 to - 5.0 kg, respectively) than with comparators (except for similar HbA1c reductions vs liraglutide). There were no statistically significant interactions by treatment and background medication subgroup for change in HbA1c or body weight except for change in HbA1c (background insulin vs insulin plus metformin) in PIONEER 8 (p = 0.0408). Changes in HbA1c and body weight were generally similar across insulin regimen subgroups, without significant treatment interactions by subgroup, and the total daily insulin dose was decreased for patients receiving oral semaglutide. The incidence of adverse events was generally similar in background medication subgroups.ConclusionOral semaglutide was effective at lowering HbA1c and body weight, regardless of background medications, and appears suitable for a broad range of patients with T2D in combination with other glucose-lowering agents.Trial registrationClinicaltrials.gov: NCT02607865 (PIONEER 3), NCT02863419 (PIONEER 4), NCT02827708 (PIONEER 5), NCT02849080 (PIONEER 7) and NCT03021187 (PIONEER 8).

Project description:Aims/hypothesisThe aim of the study was to evaluate longitudinal associations between HbA1c levels, diabetes status and subsequent cognitive decline over a 10 year follow-up period.MethodsData from wave 2 (2004-2005) to wave 7 (2014-2015) of the English Longitudinal Study of Ageing (ELSA) were analysed. Cognitive function was assessed at baseline (wave 2) and reassessed every 2 years at waves 3-7. Linear mixed models were used to evaluate longitudinal associations.ResultsThe study comprised 5189 participants (55.1% women, mean age 65.6 ± 9.4 years) with baseline HbA1c levels ranging from 15.9 to 126.3 mmol/mol (3.6-13.7%). The mean follow-up duration was 8.1 ± 2.8 years and the mean number of cognitive assessments was 4.9 ± 1.5. A 1 mmol/mol increment in HbA1c was significantly associated with an increased rate of decline in global cognitive z scores (-0.0009 SD/year, 95% CI -0.0014, -0.0003), memory z scores (-0.0005 SD/year, 95% CI -0.0009, -0.0001) and executive function z scores (-0.0008 SD/year, 95% CI -0.0013, -0.0004) after adjustment for baseline age, sex, total cholesterol, HDL-cholesterol, triacylglycerol, high-sensitivity C-reactive protein, BMI, education, marital status, depressive symptoms, current smoking, alcohol consumption, hypertension, CHD, stroke, chronic lung disease and cancer. Compared with participants with normoglycaemia, the multivariable-adjusted rate of global cognitive decline associated with prediabetes and diabetes was increased by -0.012 SD/year (95% CI -0.022, -0.002) and -0.031 SD/year (95% CI -0.046, -0.015), respectively (p for trend <0.001). Similarly, memory, executive function and orientation z scores showed an increased rate of cognitive decline with diabetes.Conclusions/interpretationSignificant longitudinal associations between HbA1c levels, diabetes status and long-term cognitive decline were observed in this study. Future studies are required to determine the effects of maintaining optimal glucose control on the rate of cognitive decline in people with diabetes.

Project description:BackgroundCombining HbA1c with glycated albumin (GA) may improve detection of dysglycaemia. As BMI correlates positively with HbA1c and negatively with GA, HbA1c may be more effective in obese and GA in nonobese individuals.MethodsTo relate these findings to Africans, we assessed in 1274 South Africans living in CapeTown (male 26%; age 48±16y; BMI 28.7 kg/m2 (range 15.6-73.8); obesity 39.9% and no prior diabetes history) the: (1) correlation of BMI with HbA1c and GA, (2) ability of HbA1c and GA separately and jointly, to detect OGTT-diagnosed dysglycaemia (diabetes plus prediabetes). Data collection took place between 2014 and 2016 in the City of Cape Town. Dysglycaemia was diagnosed by glucose criteria for the OGTT. Youden index was used to optimize diagnostic thresholds for HbA1c and GA.FindingsNormal glucose tolerance, prediabetes and diabetes occurred in 76%, 17% and 7%, respectively. BMI positively correlated with HbA1c [r = 0·34 [95%CI: 0·29,0·39)] and negatively with GA [-0·08 (0·13,0·03)]. For HbA1c the optimal threshold by Youden-index for dysglycaemia diagnosis was: 6·0% (95%CI: 5·8,6·2) and for GA: 13·44% (12·72,14·71). In the nonobese, obese and total cohort, HbA1c-alone detected: 51% (42-60), 72% (65,78), 63% (57,68), respectively; GA-alone detected 55% (52% (46,63), 52% (44, 59) and 53% (47,53), respectively; whereas: HbA1c+GA detected: 69% (60,76), 82% (75,87) and 76% (71, 81). Therefore, for the total cohort detection of dysglycaemia HbA1c-alone vs HbA1c+GA detected 63% (57,68) vs 76% (71,81).InterpretationThe opposite correlations of HbA1c and GA with BMI have now been demonstrated in an African-based population. Improving detection of dysglycaemia by combining HbA1c and GA has important implications for diabetes risk screening.FundingAES is supported by the intramural programs of the National Institute of Diabetes and Digestive and Kidney Diseases and the National Institute of Minority Health and Health Disparities of the National Institutes of Health (NIH, Bethesda, Maryland, USA).
