Effectiveness of premixed insulin to achieve glycaemic control in type 2 diabetes: A retrospective UK cohort study.

AIM: To investigate the effectiveness of premixed insulin for achieving glycaemic outcomes in clinical practice in the UK. MATERIALS AND METHODS: Electronic medical record data from The Health Improvement Network database were captured for adults with type 2 diabetes (T2D) uncontrolled (HbA1c ≥9%) on two or more oral antihyperglycaemic drugs (OADs) initiating premixed insulin. Effectiveness of premixed insulin was assessed by the probability and incidence of achieving glycaemic outcomes (target HbA1c <7.5% [<58 mmol/mol] and a ≥1% or ≥2% HbA1c reduction) over 24 months. RESULTS: Data from 974 participants (mean age 62 years; 56% male; 52% obese or extremely obese; mean HbA1c 11.3% [100 mmol/mol]; hypertension 64%, dyslipidaemia 23% and nephropathy 21%) were analysed. The probability of achieving HbA1c <7.5% was highest during months 3-6 (18.2%), while the cumulative probability of achieving this target plateaued between months 15-24 (15.7%-16.0%). Incidence of achieving all glycaemic outcomes plateaued after 12 months and differed by baseline HbA1c, but not OAD use. Factors affecting some glycaemic outcomes included a body mass index >40 kg/m2 and co-morbidities including nephropathy and stroke. CONCLUSIONS: In people with uncontrolled T2D (HbA1c ≥9%), glycaemic outcome achievement on premixed insulin was low at 6 months with little additional clinical benefit beyond 12 months, suggesting a high unmet need for early, timely treatment changes with more effective, simpler therapies.

Real-world evidence of the effectiveness on glycaemic control of early simultaneous versus later sequential initiation of basal insulin and glucagon-like peptide-1 receptor agonists.

AIM: To assess the impact of the timing of initiating both basal insulin and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) on reaching glycaemic control targets over 6 and 12 months in people with type 2 diabetes (T2D) uncontrolled on oral antihyperglycaemic drugs with an HbA1c of 9% or higher. METHODS: This retrospective cohort study assessed the impact of the timing of initiating both basal insulin and GLP-1 RA therapies on reaching glycaemic targets (HbA1c < 7% and <8%, and ≥1% and ≥2% HbA1c reduction) over 12 months in people with markedly uncontrolled T2D (HbA1c ≥ 9%) on oral antihyperglycaemic drugs identified on the Optum Humedica database (electronic medical records; 1 January 2011 to 30 June 2017). Study cohorts were defined by the days between initiating each injectable: cohort A, 30 days or less (simultaneous initiation) and cohorts B, 31-90, C, 91-180, D, 181-270 and E, 271-360 days (sequential initiation). RESULTS: Cohort A had the best glycaemic outcomes at 6 and 12 months for all four endpoints, followed by cohort B. The likelihood of achieving an HbA1c of less than 7% did not significantly differ between cohorts A and B (hazard ratio [95% confidence interval]: 0.87 [0.76-1.01]); cohorts C, D and E were significantly less likely to achieve an HbA1c of less than 7% than cohort A (0.62 [0.53-0.72]; 0.62 [0.53-0.72]; 0.63 [0.54-0.73]). CONCLUSIONS: In people with uncontrolled T2D requiring treatment with a GLP-1 RA and basal insulin, greater improvements in glycaemic control were observed when both therapies were initiated within close proximity of one another (≤90 days) compared with initiation 91-360 days apart.

Characterizing real world safety profile of oral Janus kinase inhibitors among adult atopic dermatitis patients: evidence transporting from the rheumatoid arthritis population.

OBJECTIVE: To address potential safety concerns of Janus Kinase Inhibitors (JAK-Is), we characterized their safety profile in the atopic dermatitis (AD) patient population. METHODS: In this retrospective observational study, we used propensity score-based methods and a Poisson modeling framework to estimate the incidence of health outcomes of interest (HOI) for the AD patient. To that end, two mutually exclusive cohorts were created using a real world data resource: a rheumatoid arthritis (RA) cohort, where we directly quantify the safety risk of JAK-Is on HOIs, and an AD cohort, that comprises the target population of interest and to whom we transport the results obtained from the RA cohort. The RA cohort included all adults who filled at least one prescription for a JAK-I (tofacitinib, baricitinib, or upadacitinib) between 1 January 2017 and 31 January 2020. The AD cohort consisted of all adults diagnosed with AD during the same period. We first estimated the incidence rate of each HOI in the RA cohort, and then transported the results to the AD population. RESULTS: The RA and AD cohorts included 5,296 and 261,855 patients, respectively. On average, patients in the AD cohort were younger, more often male, more likely to be Asian, and had higher household income. They also had a lower prevalence of several comorbid conditions including hypertension, chronic kidney disease, obesity, and depression. Overall, the transported incidence rates of the HOIs to the AD cohort were lower than those obtained in the RA cohort by 13-50%. CONCLUSION: We applied transportability methods to characterize the risk of the HOIs in the AD population and found absolute risks higher than that of the general population. Future work is needed to validate these conclusions in comparable populations.

Concomitant iGlarLixi and Sodium-Glucose Co-transporter-2 Inhibitor Therapy in Adults with Type 2 Diabetes: LixiLan-G Trial and Real-World Evidence Results.

INTRODUCTION: iGlarLixi, the once-daily fixed-ratio combination of insulin glargine 100 U/ml and lixisenatide, robustly improves glycaemic control in adults with type 2 diabetes irrespective of previous treatment [oral antihyperglycaemic drugs (OADs), basal insulin or glucagon-like peptide-1 receptor agonists (GLP-1 RAs)]. Sodium-glucose co-transporter-2 inhibitors (SGLT2is) are a recommended treatment option for people with type 2 diabetes with cardiovascular disease, kidney disease and/or heart failure because of their cardio- and renoprotective benefits. Herein, we assessed the effects of concomitant iGlarLixi and SGLT2i therapy. METHODS: We conducted subgroup analyses according to SGLT2i use in: (1) adults with suboptimally controlled type 2 diabetes on GLP-1 RAs and OADs switching to iGlarLixi in the 26-week LixiLan-G randomised controlled trial (RCT; NCT02787551) and (2) adults switching to or adding iGlarLixi in a 6-month, retrospective real-world evidence (RWE) observational study using data from the US Optum-Humedica electronic medical records database. Changes in HbA1c and hypoglycaemia prevalence and event rates were assessed. RESULTS: There were no major differences in baseline characteristics for those who initiated iGlarLixi while already using SGLT2i (n = 346) and those initiating iGlarLixi without concomitant SGLT2i therapy (n = 1285). HbA1c reductions from baseline to time of assessment and hypoglycaemia prevalence and event rates were similar for iGlarLixi users regardless of SGLT2i therapy. CONCLUSION: Evidence from an RCT and an RWE analysis supports the efficacy/effectiveness and safety of iGlarLixi when used concomitantly with SGLT2i. TRIAL REGISTRATION: NCT02787551.

People with type 2 diabetes require glucose-lowering drugs to attain and maintain blood glucose control, with many eventually requiring injectable therapies. iGlarLixi combines two injectable therapies (basal insulin glargine and a glucagon-like peptide-1 receptor agonist, lixisenatide) into a single fixed-ratio daily injection and has previously been shown to provide robust improvements in blood glucose control. However, previous studies have not assessed the potential effect that simultaneous use of sodium-glucose co-transporter-2 inhibitor (SGLT2i) therapy may have on iGlarLixi therapy. This is of interest because SGLT2is are a widely used oral blood-glucose-lowering therapy that also have a beneficial effect in people with type 2 diabetes who have cardiovascular or kidney disease or have risk factors for the development or progression of these conditions. Therefore, this study assessed whether there were relevant differences in terms of blood glucose control and safety when initiating iGlarLixi in people treated with SGLT2i versus initiating iGlarLixi in people not receiving SGLT2i. Results showed that iGlarLixi provided similarly good glucose control and safety profiles, regardless of whether SGLT2is were used or not, thereby supporting the simultaneous use of these two therapies.

Impact of Simultaneous Versus Sequential Initiation of Basal Insulin and Glucagon-like Peptide-1 Receptor Agonists on HbA1c in Type 2 Diabetes: A Retrospective Observational Study.

INTRODUCTION: When and how to intensify treatment in patients with type 2 diabetes (T2D) not achieving glycated hemoglobin (HbA1c) targets with oral antidiabetic drugs (OADs) in clinical practice remains a matter of clinical preference. This pilot study was conducted using the retrospective observational data from such patients to evaluate the impact on HbA1c of three treatment sequences: simultaneous initiation of basal insulin (BI) and a glucagon-like peptide-1 receptor agonist (GLP-1 RA; Cohort 1); BI followed by GLP-1 RA initiation within a 90-day timeframe (Cohort 2); or BI followed by GLP-1 RA initiation beyond 90 days (Cohort 3). METHODS: Data from the regional US electronic medical records database, Research Action for Health Network (REACHnet), were extracted for all patients with T2D aged ≥ 18 years who had encounter dates between January 2011 and August 2017 and ≥ 1 HbA1c laboratory value(s) < 90 days before BI initiation and ≥ 2 HbA1c laboratory values within 1 year after BI initiation and who met the inclusion criteria for GLP-1 RA initiation set for Cohorts 1, 2, or 3. The primary endpoints were the proportion of patients achieving HbA1c < 7.0%, which was estimated via Kaplan-Meier analysis, and change in HbA1c within 12 months. RESULTS: Overall, 869 patients were analyzed, of whom 109 were in Cohort 1, 301 in Cohort 2, and 459 in Cohort 3. Baseline HbA1c was 10.3 ± 2.1, 10.3 ± 2.0, and 10.2 ± 2.1% for these three cohorts, respectively. Statistically significantly more patients in Cohort 1 than in Cohort 3 achieved HbA1c < 7.0% (33.4 vs. 20.9%, respectively; p = 0.0186). Mean observed reductions in HbA1c at 12 months were - 1.7% (Cohort 1), - 1.5% (Cohort 2), and - 1.3% (Cohort 3). CONCLUSIONS: Simultaneous initiation of BI and GLP-1 RA achieves glycemic control more effectively than sequential initiation of BI with GLP-1 RA added beyond 90 days.

A Real-World Observational Study Evaluating the Probability of Glycemic Control with Basal Insulin or Glucagon-Like Peptide-1 Receptor Agonist in Japanese Patients with Type 2 Diabetes.

INTRODUCTION: The effectiveness of basal insulin (BI) or glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in providing glycemic control in patients with type 2 diabetes (T2D) in Japanese routine practice is not well known. This real-world observational study evaluated the probability of achieving glycemic control in Japanese patients with T2D uncontrolled by oral antidiabetic drugs (OADs) who initiated BI or GLP-1 RA therapy. METHODS: Patients with T2D aged ≥ 18 years initiating BI or GLP-1 RA therapy following treatment with OADs were selected from real-world data (RWD) retrieved from a large electronic medical record database in Japan, using data from 01 January 2010 to 30 June 2019. Patients were required to have glycated hemoglobin (HbA1c) ≥ 7% within 90 days prior to the first prescription of BI or GLP-1 RA. The probability of reaching first HbA1c < 7% was assessed over a 24-month period in cohorts of patients who initiated BI (n = 3477) or GLP-1 RA (n = 780) and in subcohorts by number of OADs at baseline (1, 2, or ≥ 3), HbA1c at baseline (≥ 7 to < 8%, ≥ 8 to < 9%, or ≥ 9%), and age (< 65 or ≥ 65 years). RESULTS: Mean (standard deviation) baseline HbA1c was 9.4% (1.8%) and 8.8% (1.4%) in patients initiating BI or GLP-1 RA therapy, respectively. The cumulative probability of achieving glycemic control was 50.1% with BI and 60.3% with GLP-1 RA therapy, respectively, at 12 months, and 60.8% and 66.6%, respectively, at 24 months. Quarterly (3-month intervals) conditional probabilities of achieving glycemic control decreased over time and were < 10% after 12 months. Patients with more OADs or higher HbA1c at baseline had a lower probability of achieving glycemic control. CONCLUSION: Among Japanese patients with T2D who initiated BI or GLP-1 RA therapy after treatment with OADs, the probability of reaching first glycemic control diminished over time. Further therapy intensification is warranted in patients who do not achieve glycemic control within 6-12 months with BI or GLP-1 RA, particularly those with high HbA1c or taking multiple OADs.

Patients with type 2 diabetes (T2D) who are taking oral antidiabetic drugs (OADs) but still have high blood glucose often require injectable drugs, such as basal insulin (BI) or glucagon-like peptide-1 receptor agonists (GLP-1 RAs). While BI and GLP-1 RAs have been shown to be effective in controlled clinical trials, it is unclear how well they improve blood glucose in real-world routine practice. Here, we report the results of an observational study that used data retrieved from a large electronic medical records database in Japan to explore how well BI and GLP-1 RAs allow patients to achieve glycemic control [glycated hemoglobin (HbA1c) < 7%].In Japanese patients with T2D receiving treatment with OADs and initiating BI or GLP-1 RA therapy, the probability of achieving glycemic control in the first quarter (3 months) after initiation was 20.3% with BI and 38.6% with GLP-1 RA. Among those patients who had not previously reached glycemic control, the probability of achieving first glycemic control declined over time, as evidenced in each quarterly assessment, and it was < 10% after the first year. Patients who had higher HbA1c levels or were taking multiple OADs were less likely to achieve glycemic control compared with those with lower HbA1c or taking fewer OADs. Our findings suggest that patients who have not achieved their glycemic goals within the first 6­12 months after starting BI or GLP-1 RA therapy have a low likelihood of achieving their target by maintaining the same therapy. For such patients, intensification with additional medication (e.g., combined BI and GLP-1 RA therapy) should be considered early in treatment.

Glycemic Control Following GLP-1 RA or Basal Insulin Initiation in Real-World Practice: A Retrospective, Observational, Longitudinal Cohort Study.

INTRODUCTION: Injectable therapies such as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and basal insulin (BI) are well-established agents for people with type 2 diabetes (T2D). This study aimed to investigate real-world effectiveness of GLP-1 RAs or BI in adults with T2D poorly controlled on oral antihyperglycemic drugs (OADs). METHODS: This was a retrospective, observational, longitudinal cohort study of adults with T2D from the US Optum Humedica® database and UK Clinical Practice Research Datalink, who initiated either injectable between January 1, 2010, and June 30, 2016. Baseline characteristics, glycated hemoglobin (HbA1c) change, and cumulative percentage reaching HbA1c < 7% in 24 months after initiation were analyzed in four patient cohorts. RESULTS: In the US and UK databases, respectively, 20,836 and 5508 patients initiated GLP-1 RAs and 60,598 and 5083 initiated BI. Baseline mean HbA1c at initiation ranged between 8.8% and 10.3% across all cohorts. In all cohorts, a decrease of HbA1c occurred 3-6 months after initiation. The cumulative percentage of patients reaching HbA1c < 7% showed the greatest probability in the first 12 months (15-40% of patients across cohorts at 12 months), particularly in the first 6 months after initiation. The probability of reaching glycemic control diminished after the second quarter. The proportion of patients reaching HbA1c < 7% in both GLP-1 RA and BI cohorts at 12 months was < 25% if baseline HbA1c was ≥ 9%. CONCLUSIONS: For adults with T2D inadequately controlled on OADs, this analysis reveals an unmet clinical need. Initiation of first injectable therapy did not occur until HbA1c was considerably above target, when control is harder to achieve. Results suggest that in individuals with baseline HbA1c ≥ 9.0%, only a minority are likely to achieve an HbA1c < 7% with a GLP-1 RA or BI alone.

Chronic kidney disease among US adults with type 2 diabetes and cardiovascular diseases: A national estimate of prevalence by KDIGO 2012 classification.

AIM: Data on prevalence of chronic kidney disease (CKD) among US adults with type 2 diabetes (T2D) and cardiovascular diseases (CVD) are limited. The aim of this study was to provide such estimates for T2D, both overall and in those with CVD. MATERIALS AND METHODS: Using the NHANES 2007-2014 data, we conducted a cross-sectional analysis of an adult sample with diagnosed and undiagnosed T2D, aged ≥18 years. CVD was defined based on self-reported personal interview data on a broad range of health conditions-congestive heart failure, coronary heart disease, angina, stroke, or heart attack. T2D was defined as diagnosed T2D (self-reported provider diagnosis) and undiagnosed T2D (FPG ≥126 mg/dL or HbA1c ≥ 6.5% without self-reported diagnosis). Participants who started insulin within a year of T2D diagnosis, or were pregnant at the time of health examination were excluded. Appropriate sample weights were used to provide a national estimate. RESULTS: The prevalence of moderate to severe renal impairment based on eGFR below 60 ml/min/1.73 m2 among T2D was 18.0%. The prevalence of mild renal impairment was 36.9%: 28.3% with UACR<30 mg/g, 7.0% with UACR ≥30-300 mg/g and 1.6% with UACR >300 mg/g. For T2D and CVD subgroup, the prevalence was 33.6% for moderate to severe renal impairment and 42.8% for mild renal impairment. CONCLUSIONS: This study confirms the high prevalence of CKD in patients with multiple comorbidities: T2D and CVD. It also provides estimates of the prevalence of CKD categories based on KDIGO 2012 classification for US adults with T2D.

The expanding national burden of heart failure in the United States: the influence of heart failure in women.

BACKGROUND: Although some studies have shown that hospital admissions for heart failure doubled between 1973 and 1995, other data suggest that the heart failure hospitalization epidemic has stabilized in the United States. We sought to describe trends in heart failure hospitalizations over the past decade using data from the National Hospital Discharge Survey (NHDS). METHODS: The NHDS provides annual estimates of hospitalization discharges from a sample of hospitals in the United States. We combined the heart failure hospitalization frequencies with census estimates to calculate age and gender-specific annual hospitalization rates. RESULTS: Hospitalizations with a primary diagnosis of heart failure among adults (age > or =35) increased from 810,624 in 1990 to 989,500 in 1995 (annual increase 36,088, R2 = 0.816, P =.014), and to 1,088,349 in 1999 (annual increase 31,091, R2 = 0.780, P =.047). The age-adjusted hospitalization rate (per 1000 persons) increased from 7.186 in 1990 to 8.554 in 1999 for women (annual increase 0.14/year, R2 = 0.731, P =.002) and from 6.892 in 1990 to 7.372 in 1999 for men (annual increase 0.011/year, R2 = 0.008, P = 0.80). For women, the annual hospitalization rate increased from 1990 to 1999 in each age group (35-64, 65-74, 75-84, and > or =85), while the age-specific rates did not change in men. CONCLUSIONS: Heart failure hospitalizations have continued to increase from 1990 to 1999. Although aging and growth of the US population contribute to this trend, the increases are substantially influenced by changes in hospitalization rates in women.
