Type 2 Diabetes, Hypoglycemia, and Basal Insulins: Ongoing Challenges

Effects of age and disease duration on the efficacy and safety of iGlarLixi in Asian people with type 2 diabetes: A post hoc analysis of the LixiLan-O-AP and LixiLan-L-CN trials

AIM

To evaluate the effect of age and disease duration on the efficacy and safety of iGlarLixi versus insulin glargine 100 units/ml (iGlar) or lixisenatide (Lixi) alone in Asian people with type 2 diabetes (T2D) uncontrolled on oral antidiabetic drugs (LixiLan-O-AP) or basal insulin ± oral antidiabetic drugs (LixiLan-L-CN).

MATERIALS AND METHODS

In this post hoc analysis, the glycated haemoglobin (HbA1c) changes were assessed from baseline to week 24 (LixiLan-O-AP) or 30 (LixiLan-L-CN) in subgroups defined by baseline age (<65, ≥65 years) and duration of T2D. The proportion who achieved the composite of HbA1c <7% (<53.0 mmol/mol) without weight gain and without symptomatic hypoglycaemia (plasma glucose ≤3.9 mmol/L) and the incidences of hypoglycaemia and gastrointestinal disorders were also analysed.

RESULTS

HbA1c reductions were consistently greater with iGlarLixi versus iGlar or Lixi across all subgroups, including participants aged ≥65 years and those with T2D for ≥15 or ≥20 years. Greater proportions of participants achieved HbA1c <7% (<53.0 mmol/mol) without weight gain or hypoglycaemia with iGlarLixi versus iGlar or Lixi, regardless of age or T2D duration. Hypoglycaemia incidence was similar with iGlarLixi versus iGlar across most subgroups; the incidence of gastrointestinal disorders was lower with iGlarLixi versus Lixi in all subgroups.

CONCLUSIONS

iGlarLixi showed consistent efficacy and safety across all age and disease duration subgroups in Asian people with uncontrolled T2D, including older individuals and those with longstanding disease.

Chinese patent medicine as a complementary and alternative therapy for type 2 diabetes mellitus: A scoping review

OBJECTIVE

This scoping review aims to document Chinese Patent Medicines (CPMs) for Type 2 Diabetes Mellitus, explore whether CPMs can improve patients' health outcomes, and set priorities in addressing research gaps in this area.

METHODS

Following the framework of PRISMA-SCr, we proposed the research questions based on PICOS principle, and searched the CPMs for T2DM from three drug lists, followed by a systematic search of the literature in eight databases from their inception to June 22, 2023. Then, we developed the eligibility criteria and systematically reviewed the relevant studies, retained the studies about CPMs for T2DM, extracted the related data, and identified the differences across studies in structured charts.

RESULTS

A total of 25 types of CPMs were extracted from the three drug lists. Radix astragali appeared most frequently (19 times) among the herbal medicinal ingredients of CPMs. A total of 449 articles were included in the full-paper analysis ultimately, all of which were about 20 types of CPMs, and there were no related reports on the remaining five CPMs. Except about a quarter (25.39 %, 114/449) using CPMs alone, the remaining studies all involved the combination with oral hypoglycemics for T2DM. Biguanides are the most common drugs used in combination with CPMs (50.14 %, 168/335). Fasting plasma glucose (FPG) is the most frequently reported outcomes in efficacy evaluation (82.41 %, 370/449).

CONCLUSION

There are a total of 25 types of CPMs currently available for T2DM patients. However, the volume of related evidence on these CPMs varies. It is necessary to standardize the combined use of CPMs and conventional medicine and select appropriate outcomes in future studies.

Evaluating Patient and Provider Preferences for a Once-Weekly Basal Insulin in Adults with Type 2 Diabetes

Purpose

The global burden of disease of type 2 diabetes (T2D) is significant, and insulin currently plays a central role in T2D management. This study sought to assess the preferences of patients with T2D and healthcare providers (HCPs) involved in T2D care regarding a hypothetical once-weekly basal insulin in comparison to current basal insulin options.

Patients and Methods

In a survey-based study in the United States that included a discrete choice experiment (DCE), patients with T2D (insulin naïve and current insulin users) and providers who treat individuals with T2D were asked to evaluate current basal insulins and identify attributes of importance regarding a hypothetical once-weekly basal insulin. A regression analysis was conducted to identify drivers of preference by relevant demographics, attitudes, and behaviors.

Results

Most respondents (91% of patients with T2D and 89% of HCPs in the base case scenario) would choose a once-weekly basal insulin product over another type of basal insulin. Both patients with T2D and HCPs rated insulin type and delivery method to be attributes of highest importance in the discrete choice exercise. Current basal insulin users ("insulin experienced") reported higher levels of confidence that a once-weekly insulin would help them to achieve their desired blood sugar levels compared to their current basal insulin (5.7 vs 5.2 on a 7-point Likert scale). Most insulin-experienced respondents (88%) were likely to inquire about once-weekly basal insulin, and most HCPs (85%) indicated willingness to educate patients on management of their T2D using a once-weekly basal insulin.

Conclusion

Discussing preferences for T2D medication management is important for patients and HCPs to ensure treatments are offered for patients based on their preferences. This study showed that patient and provider preferences are similar towards a once-weekly basal insulin over current basal insulin preparations.

Hypoglycemia in diabetes: An update on pathophysiology, treatment, and prevention

Hypoglycemia is a common complication in patients with diabetes, mainly in those treated with insulin, sulfonylurea, or glinide. Impairments in counterregulatory responses and hypoglycemia unawareness constitute the main risk factors for severe hypoglycemia. Episodes of hypoglycemia are associated with physical and psychological morbidity. The fear of hypoglycemia constitutes a barrier that impairs the patient’s ability to reach good glycemic control. To prevent hypoglycemia, much effort must be invested in patient education regarding risk factors, warning signs, and treatment of hypoglycemia at an early stage, together with setting personalized goals for glycemic control. In this review, we present a comprehensive update on the treatment and prevention of hypoglycemia in type 1 and type 2 diabetic patients.

Dulaglutide and Insulin: How Can the AWARD Studies Help Guide Clinical Practice?

The glucagon-like peptide 1 receptor agonist (GLP-1RA) dulaglutide has many characteristics to recommend it both as a second-line agent and as an alternative to or in combination with insulin. This commentary summarises recent updates to diabetes management guidelines regarding the use of GLP-1RAs such as dulaglutide, both as a second-line agent and as a first-line injectable agent in type 2 diabetes (T2D). It also examines how the Assessment of Weekly AdministRation of LY2189265 [dulaglutide] in Diabetes (AWARD) studies with dulaglutide and insulin may help to guide clinical practice for the use of dulaglutide as an alternative to basal insulin or in combination with insulin.Individualising glucose-lowering therapy is important in patients with T2D, especially given patients' heterogeneity in terms of age, lifestyle, disease duration, level of hyperglycaemia and comorbidities. Choice of therapy should be guided by clinical considerations (e.g. high risk or existing cardiovascular [CV] disease, heart failure, chronic kidney disease, risk of hypoglycaemia), side effect profile, contraindications, patient preferences and cost. The recently updated American Diabetes Association/European Association for the Study of Diabetes (ADA/EASD) guidelines now recommend adding a GLP-1RA with proven CV benefit to metformin in patients with T2D and indicators of high risk or established atherosclerotic CV disease. The AWARD studies demonstrate that dulaglutide provides effective glucose lowering together with sustained weight loss and a low incidence of hypoglycaemia when used as the first injectable option and when used in combination with titrated basal insulin or prandial insulin, providing a valid treatment option across a wide range of patients with T2D, including those with chronic kidney disease.

Combination of basal insulin and GLP-1 receptor agonist: is this the end of basal insulin alone in the treatment of type 2 diabetes?

Glycemic control has been considered a major therapeutic goal within the scope of diabetes management, as supported by robust observational and experimental evidence. However, the coexistence of micro and macrovascular disease is associated with the highest cardiovascular risks which highlights the importance that pharmacological treatment of type 2 diabetes mellitus provides not only glycemic control, but also cardiovascular safety. Basal insulin is a highly effective treatment in reducing fasting blood glucose, but it is associated with considerable risk of hypoglycemia and weight gain. Glucagon like peptide 1 receptor agonists (GLP-1 RAs) are also effective in terms of glycemic control and associated with weight loss and low risk of hypoglycemia. The potential benefits of combining GLP-1RAs with basal insulin are contemplated in the current position statement of several different position statement and guidelines. This article reviews the efficacy and safety of different strategies to initiate and intensify basal insulin, with focus on new fixed ratio combinations of basal insulin with GLP-1 RAs available for use in a single injection pen (insulin degludec/liraglutide and insulin glargine/lixisenatide).

An international survey on hypoglycemia among insulin-treated type I and type II diabetes patients: Turkey cohort of the non-interventional IO HAT study

BACKGROUND

Limited real-world data are currently available on hypoglycemia in diabetes patients. The International Operations Hypoglycemia Assessment Tool (IO HAT) study was designed to estimate hypoglycemia in insulin-treated type I (T1DM) and type II (T2DM) diabetes mellitus patients from 9 countries. The data from Turkey cohort are presented here.

METHODS

A non-interventional study to determine the hypoglycemia incidence, retrospectively and prospectively, in Turkish T1DM and T2DM patients using a 2-part self-assessment questionnaire.

RESULTS

Overall, 2348 patients were enrolled in the Turkey cohort (T1DM = 306 patients, T2DM = 2042 patients). In T1DM patients, 96.8% patients reported hypoglycemic events (Incidence rate [IR]: 68.6 events per patient-year [ppy]), prospectively, while 74.0% patients reported hypoglycemic events (IR: 51.7 events ppy), retrospectively. In T2DM patients, 95.9% patients (IR: 28.3 events ppy) reported hypoglycemic events, prospectively, while 53.6% patients (IR: 23.0 events ppy) reported hypoglycemic events, retrospectively. Nearly all patients reported hypoglycemia during the prospective period.

CONCLUSIONS

This is a first patient-reported dataset on hypoglycemia in Turkish, insulin-treated diabetes patients. A high incidence of patient-reported hypoglycemia confirms that hypoglycemia remains under-estimated. Hypoglycemia increased healthcare utilization impacting patients' quality of life. Hypoglycemia remains a common side effect with insulin-treatment and strategies to optimize therapy and reduce hypoglycemia occurrence in diabetes patients are required.

Fasting-Evoked En Route Hypoglycemia in Diabetes (FEEHD): An Overlooked Form of Hypoglycemia in Clinical Practice

OBJECTIVE

Many patients with diabetes opt to fast for lab tests, especially for lipid profiles, thus missing breakfast. In parallel, recent studies and international guidelines have indicated that routine fasting for lipid panels may not be necessary. Missing breakfast while fasting for lab tests may invoke hypoglycemia, if patients are not properly instructed about adjusting diabetes medications on the night before or on the day of the lab test. Our group described this form of hypoglycemia and introduced the term FEEHD to refer to it (fasting-evoked en route hypoglycemia in diabetes). In a recently published small study, we reported a rate of occurrence of FEEHD of 27.1%. The objective of this study was to evaluate the rate of occurrence of FEEHD in another clinic.

METHODS

Patients with diabetes were asked to complete a simple, 2-page survey inquiring about hypoglycemic events while fasting for labs in the preceding 12 months.

RESULTS

A total of 525 patients completed the surveys out of 572 patients invited (91.8% response rate). A total of 363 patients with complete data were analyzed, with a mean age of 60.6 (SD 12.5) years. A total of 62 (17.1%) patients reported having experienced one or more FEEHD events in the prior 12 months. Of the 269 patients who were at higher risk of FEEHD (on insulin secretagogues or on insulin), 59 (21.9%) reported having experienced FEEHD. Only 33 of FEEHD patients (53%) recalled having contacted their provider regarding the events and only 22 (35%) indicated having received some sort of FEEHD prevention instructions.

CONCLUSION

Our study shows a significant rate of occurrence of FEEHD in the real world (a clinical practice). FEEHD is especially dangerous, as patients often commute (drive) to and from the laboratory facility (potential risk of traffic accidents). Given study limitations, further studies are needed to assess prevalence of FEEHD in other settings and in the general populations.
