Project description:ObjectiveTo investigate the long term effects of continuous subcutaneous insulin infusion (insulin pump therapy) on cardiovascular diseases and mortality in people with type 1 diabetes.DesignObservational study.SettingSwedish National Diabetes Register, Sweden 2005-12.Participants18,168 people with type 1 diabetes, 2441 using insulin pump therapy and 15,727 using multiple daily insulin injections.Main outcome measuresCox regression analysis was used to estimate hazard ratios for the outcomes, with stratification of propensity scores including clinical characteristics, risk factors for cardiovascular disease, treatments, and previous diseases.ResultsFollow-up was for a mean of 6.8 years until December 2012, with 114,135 person years. With multiple daily injections as reference, the adjusted hazard ratios for insulin pump treatment were significantly lower: 0.55 (95% confidence interval 0.36 to 0.83) for fatal coronary heart disease, 0.58 (0.40 to 0.85) for fatal cardiovascular disease (coronary heart disease or stroke), and 0.73 (0.58 to 0.92) for all cause mortality. Hazard ratios were lower, but not significantly so, for fatal or non-fatal coronary heart disease and fatal or non-fatal cardiovascular disease. Unadjusted absolute differences were 3.0 events of fatal coronary heart disease per 1000 person years; corresponding figures were 3.3 for fatal cardiovascular disease and 5.7 for all cause mortality. When lower body mass index and previous cardiovascular diseases were excluded, results of subgroup analyses were similar to the results from complete data. A sensitivity analysis of unmeasured confounders in all individuals showed that an unmeasured confounders with hazard ratio of 1.3 would have to be present in >80% of the individuals treated with multiple daily injections versus not presence in those treated with pump therapy to invalidate the significantly lower hazard ratios for fatal cardiovascular disease. Data on patient education and frequency of blood glucose monitoring were missing, which might have influenced the observed association.ConclusionAmong people with type 1 diabetes use of insulin pump therapy is associated with lower cardiovascular mortality than treatment with multiple daily insulin injections.

Project description:Study questionWhat are the effects of liraglutide, an incretin based treatment, on glycaemic control in people with type 2 diabetes treated with multiple daily insulin injections?MethodsThe study was a randomised, double blind, placebo controlled trial with a parallel group design carried out at 13 hospital based outpatient clinics and one primary care unit in Sweden. Patients were considered eligible for inclusion if they had type 2 diabetes and inadequate glycaemic control (HbA1c concentrations ≥ 58 mmol/mol (7.5%) and ≤ 102 mmol/mol (11.5%)), a body mass index of 27.5-45 kg/m(2), and required multiple daily insulin injections. Overall, 124 participants were randomised 1:1 to subcutaneous liraglutide or placebo by minimisation allocation. The main outcome measure was change in HbA1c level from baseline to week 24.Study answer and limitationsLiraglutide was associated with a significant reduction of 16.9 mmol/mol (1.5%) in HbA1c versus 4.6 mmol/mol (0.4%) for placebo, difference -12.3 mmol/mol (95% confidence interval -15.8 to -8.8 mmol/mol; -1.13%, -1.45 to -0.81 mmol/mol). Body weight was significantly reduced in participants in the liraglutide compared with placebo group (3.8 v 0.0 kg, difference -3.8, -4.9 to -2.8 kg), and total daily insulin doses were significantly reduced, by 18.1 units and 2.3 units (difference -15.8, -23.1 to -8.5 units). Reductions in mean and standard deviation of glucose levels estimated by masked continuous glucose monitoring were significantly greater in the liraglutide group than placebo group (-1.9 and -0.5 mmol/L). Neither group experienced severe hypoglycaemic events nor were there any significant differences in symptomatic or asymptomatic non-severe hypoglycaemia (<4.0 or <3.0 mmol/L). The mean number of non-severe symptomatic hypoglycaemic events (<4.0 mmol/L) during follow-up was 1.29 in the liraglutide group and 1.24 in the placebo group (P=0.96). One of the study's limitations was its relatively short duration. Sustained effects of liraglutide have, however, been found over lengthier periods in connection with other treatment regimens. Cardiovascular safety and potential adverse events during longer exposure to liraglutide need to be evaluated. Nausea was experienced by 21 (32.8%) participants in the liraglutide group and 5 (7.8%) in the placebo group and 3 (5%) and 4 (7%) participants in these groups, respectively, had any serious adverse event.What this study addsAdding liraglutide to multiple daily insulin injections in people with type 2 diabetes improves glycaemic control without an increased risk of hypoglycaemia, reduces body weight, and enables patients to lower their insulin doses.Funding, competing interests, data sharingThis study was an investigator initiated trial, supported in part by Novo Nordisk and InfuCare.

Project description:Diabetes mellitus (DM) has a growing prevalence worldwide, even in developing countries. Many antidiabetic agents are used to improve glycemic control; however, in cases of an insufficient outcome, insulin is administered. Yet, the timing of proper insulin administration is still a subject of intense research. To date, there have been no recommendations or guidelines for the use of continuous subcutaneous insulin infusion (CSII) in Type 2 Diabetes Mellitus (T2DM). In the present study, we have performed a meta-analysis to evaluate the use of CSII in patients with T2DM. An extensive literature search was conducted through the electronic databases Pubmed, Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) from October 2019-May 2022, for interventional studies related to T2DMI and CSII versus multiple daily injections (MDI). We included articles published in the English language only, yielding a total of thirteen studies. We found better outcomes in patients receiving CSII, in regard to glycated hemoglobin (HbA1c) and total insulin dose. In contrast, fasting plasma glucose and body weight did not show statistically significant differences between the two groups. Our analyses showed that CSII could be beneficial in patients with T2DM in order to achieve their glucose targets.

Project description:AimsBoth hyperglycaemia and large glycaemic variability are associated with worse outcomes in patients with Type 2 diabetes mellitus (T2DM), possibly causing sympatho-vagal imbalance and endothelial dysfunction. Continuous subcutaneous insulin injection (CSII) improves glycemic control compared to multiple daily insulin injections (MDI). We aimed to assess whether CSII may improve cardiac autonomic and vascular dilation function compared to MDI.MethodsWe enrolled T2DM patients without cardiovascular disease with poor glycaemic control, despite optimized MDI therapy. Patients were randomized to continue MDI (with multiple daily peripheral glucose measurements) or CSII; insulin dose was adjusted to achieve optimal target ranges of blood glucose levels. Patients were studied at baseline and after 6 months by: 1) flow-mediated dilation (FMD) and nitrate-mediated dilation (NMD) of the brachial artery; 2) heart rate variability (HRV) by 24-hour ECG Holter monitoring (HM). 7-day continuous glucose monitoring (CGM) was performed in 9 and 8 patients of Group 1 and 2, respectively.ResultsOverall, 21 patients were enrolled, 12 randomized to CSII (Group 1) and 9 to MDI (Group 2). The daily dose of insulin and Hb1AC did not differ significantly between the 2 groups, both at baseline and at follow-up. Glucose variability showed some significant improvement at follow-up in the whole population, but no differences were observed between the 2 groups. Both FMD and NMD, as well as HRV parameters, showed no significant differences between the 2 groups at 6-month follow-up.ConclusionsIn this randomized small study we show that, in T2DM patients, CSII achieves a similar medium-term glycemic control compared to MDI, without any adverse effect on the cardiovascular system.

Project description:Aims/Introduction:? An insulin analogue formulation with a 7:3 ratio of rapid-acting and intermediate-acting fractions, biphasic insulin aspart 70 (BIAsp70) was developed to supplement basal insulin between meals and mimic the physiological pattern of postprandial insulin secretion.? We carried out a randomized, open-label study to compare the efficacy and safety profiles of BIAsp70 and an insulin analogue formulation with a 3:7 ratio of rapid-acting and intermediate-acting fractions (BIAsp30) in type 2 diabetes mellitus patients. Patients were randomized and received either thrice-daily BIAsp70 (n?=?145) or twice-daily BIAsp30 (n?=?144) for 28?weeks. The primary end-point was glycated hemoglobin (HbA1c) after 16?weeks of treatment.? Non-inferiority of BIAsp70 vs BIAsp30 was confirmed and superiority was established with a between-group difference (BIAsp70-BIAsp30) in HbA1c after 16?weeks of treatment of -0.35% (95% CI: -0.51 to -0.19; P?<?0.0001 for superiority). The mean postprandial glucose increment (19.96 vs 54.35?mg/dL; P?<?0.0001) and M-value (12.99 vs 17.94; P?<?0.0001) at 16?weeks were smaller in the BIAsp70 group than in the BIAsp30 group, and were maintained at 28?weeks. Pre-breakfast glucose (157.9 vs 140.7?mg/dL), total insulin dose (46.8 vs 38.1?U/day) and weight gain (+1.94 vs 1.23?kg) at week 28 were greater in the BIAsp70 group. Incidence of nocturnal hypoglycemia was significantly lower with BIAsp70 vs BIAsp30 (1.23 vs 3.21?events/subject year; P?=?0.0002) at week 28.? Thrice-daily BIAsp70 was superior to twice-daily BIAsp30 in terms of HbA1c change, with less variation in daytime plasma glucose profiles. BIAsp70 was well tolerated, with a lower incidence of nocturnal hypoglycemia vs BIAsp30. This trial was registered with ClinicalTrial.gov (no. NCT00318786).

Project description:AimTo compare the safety and efficacy of U500-R delivered by a novel, specifically designed U500-R insulin pump with U-500R delivered by multiple daily injections (MDI).MethodsThe phase 3 VIVID study randomized people with type 2 diabetes to U-500R by continuous subcutaneous insulin infusion (CSII) or MDI. Participants (aged 18-85 years) had HbA1c ≥7.5% and ≤12.0% and a total daily dose of insulin >200 and ≤600 U/day. After a 2-week transition to three times daily injections of U-500R, participants were treated for 24 weeks with U-500R by CSII or MDI. Treatment arms were compared using mixed model repeated measures analysis.ResultsThe study randomized 420 participants (CSII: 209, MDI: 211) with 365 completers. Mean changes from baseline were: HbA1c, -1.27% (-13.9 mmol/mol) with CSII and -0.85% (-9.3 mmol/mol) with MDI (difference - 0.42% [-4.6 mmol/mol], P <0.001); fasting plasma glucose, -33.9 mg/dL (-1.9 mmol/L) with CSII and 1.7 mg/dL (0.09 mmol/L) with MDI (difference - 35.6 mg/dL [-2.0 mmol/L], P <0.001); total daily dose, 2.8 U with CSII and 51.3 U with MDI (P < 0.001). Weight changes and rates of documented symptomatic and severe hypoglycaemia were similar between groups; the CSII group had a higher rate of nocturnal hypoglycaemia.ConclusionsIn type 2 diabetes requiring high doses of insulin, both methods of U-500R delivery lowered HbA1c. However, the CSII group attained greater HbA1c reduction with significantly less insulin. Individualized dose titration will be important to balance glycaemic control with hypoglycaemia risk.

Project description:IntroductionChanges to Treatment and Outcomes in Patients with Type 2 Diabetes Initiating Injectable Therapy (CHOICE) is a European prospective, observational cohort study assessing time to, and factors associated with, a significant change in therapy after type 2 diabetes patients initiate their first injectable glucose-lowering therapy, and these patients' clinical outcomes over 24 months. The authors report baseline data and factors associated with the injectable treatment regimen.MethodsDemographic, clinical, and healthcare resource-use data were collected at initiation of injectable therapy and analyzed using univariate tests between cohorts and multivariate logistic regression analysis for treatment.ResultsOverall, 1,177 patients initiated exenatide twice daily (b.i.d.) and 1,315 initiated insulin. Most patients were recruited by secondary-care physicians. Univariate analyses revealed statistically significant differences between the characteristics of patients who initiated exenatide b.i.d. and patients who initiated insulin. On multivariate analysis, higher body mass index [BMI; 5 kg/m(2) higher: odds ratio (OR) 2.10, 95% confidence intervals (CI) 1.84-2.40], lower glycated hemoglobin (HbA(1c); 1% higher: OR 0.77, 95% CI 0.69-0.86), and lower age (5 years older: OR 0.82, 95% CI 0.76-0.88) were the variables most strongly associated with increased probability of receiving exenatide b.i.d. (P < 0.0001). Patients initiating exenatide b.i.d. had a mean BMI of 35.3 ± 6.5 kg/m(2), HbA(1c) of 8.4 ± 1.4%, and age of 58 ± 10 years, compared with 29.7 ± 5.4 kg/m(2), 9.2 ± 1.9%, and 64 ± 11 years, respectively, in patients initiating insulin (P < 0.0001). Other characteristics significantly associated with exenatide b.i.d. initiation were "disinhibited eating" (Diabetes Health Profile-18), lower random blood glucose, less blood glucose self-monitoring, lower low-density lipoprotein cholesterol, and receipt of diet/exercise advice.ConclusionsPatients who initiated exenatide b.i.d. were on average younger and more obese with lower HbA(1c) than those initiating insulin.

Project description:BACKGROUND:The majority of therapies have generally targeted fasting glucose control, and current mealtime insulin therapies have longer time action profiles than that of endogenously secreted insulin. The primary purpose of this study was to assess both glucose time-in-range (TIR: 70-180?mg/dL) and postprandial glucose excursions (PPGE) in 1-4?h using a real-time continuous glucose monitor (CGM) with Technosphere insulin (TI) versus insulin aspart in patients with type 1 diabetes (T1DM) on multiple daily injections (MDI). RESEARCH DESIGN AND METHODS:This pilot, investigator-led, collaborative, open-label, multicenter, clinical research trial enrolled 60 patients with T1DM with HbA1c levels ?6.5% and ?10%. Individuals were randomized to treatment with titrated TI (n?=?26) or titrated insulin aspart (n?=?34), stratified by baseline HbA1c levels (?8% or >8%). All were required to wear a real-time CGM throughout the trial. All patients in the TI group were advised to take supplemental inhalations at 1 and 2?h after meals if indicated based on postprandial glucose (PPG) values. The coprimary outcomes were assessed both in the full intent-to-treat population and in those individuals randomized to TI who were compliant with supplemental doses ?90% of the time (n?=?15). The CGM data were analyzed using linear regression models. RESULTS:Overall, those treated with TI versus aspart achieved comparable TIR, but less time spent in hypoglycemia (<60 and <50?mg/dL, both P?<?0.05). In the TI-compliant group (n?=?15), TIR was significantly greater (62.5%?±?2.6% vs. 53.8%?±?1.7%, P?=?0.009) and time in hyperglycemia >180?mg/dL was lower (34.2%?±?2.7% vs. 41.0%?±?1.7%, P?=?0.045) as compared with the aspart group. PPG was also significantly lower in the TI cohort at 60 and 90?min postmeal, and PPGE were lower in the TI-compliant group as compared with the aspart group over 1-4-h postmeal (P?<?0.05). In addition, there was weight gain in the aspart group compared with weight loss in the TI group (P?=?0.006) despite higher prandial TI insulin dose. CONCLUSIONS:We conclude that using TI appropriately at mealtimes with supplemental dosing improves prandial glucose (TIR and 1-4?h) control without any increase in time in hypoglycemia or weight gain in patients with T1DM on MDI. The study results support a larger study using a treat-to-target design to confirm these findings. Clinical trial reg. no. NCT03143816, clinicaltrials.gov .

Project description:ObjectiveTo investigate concentration of plasma insulin glargine after its subcutaneous dosing compared with concentration of its metabolites 1 (M1) and 2 (M2) in subjects with type 2 diabetes.Research design and methodsNine subjects underwent a 32-h euglycemic glucose clamp study (0.4 units/kg glargine after 1 week of daily glargine administration). Glargine, M1, and M2 were measured by a specific liquid chromatography-tandem mass spectrometry assay.ResultsGlargine was detected in only five of the nine subjects, at few time points, and at negligible concentrations. M1 was detected in all subjects and exhibited the same pattern as traditional radioimmunoassay-measured plasma insulin. M2 was not detected at all.ConclusionsAfter subcutaneous injection, glargine was minimally detectable in blood, whereas its metabolite M1 accounted for most (>90%) of the plasma insulin concentration and metabolic action of the injected glargine.

Project description:IntroductionThe benefits of continuous glucose monitoring (CGM) in type 1 diabetes have been established among adults using insulin pumps. The DIAMOND randomized clinical trial examined the effectiveness of using CGM in improving glycemic control in participants using insulin injections. The frequency of hypoglycemic events in this trial has not been previously examined.MethodsAdults with type 1 diabetes using multiple daily insulin injections (MDI) with A1C values of 7.5% to 9.9% and not using CGM were randomized to adopt CGM (CGM group, n = 105) or continue with usual care (control group, n = 53). CGM data were collected from both groups at the beginning of the study and after 3 and 6 months. A hypoglycemic event was defined as a series of at least CGM values less than 3.0 mmol/L, separated by 20 min or more, with no intervening values of 3.0 mmol/L or more. Hypoglycemic event rates per 24 h were compared using a linear model adjusted for the baseline event rate per 24 h, baseline A1C, and site as a random effect.ResultsIn the CGM group, the median hypoglycemic event rate fell by 30% (0.23 per 24 h at baseline and 0.16 per 24 h at follow-up) while in the control group the rate was nearly unchanged (0.31 per 24 h at baseline and 0.30 per 24 h at follow-up; p value = 0.03).ConclusionIn the DIAMOND randomized controlled trial, participants in the CGM group experienced a greater reduction in hypoglycemic event rate than participants receiving usual care in the control group.Trial registrationClinicaltrials.gov Identifier: NCT02282397.
