Ambulatory noninsulin treatment of type 2 diabetes mellitus in the United States, 2015 to 2019

Use of sodium-glucose cotransporter-2 inhibitors in France: Analysis of French nationwide health insurance database

AIM

Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) have been commercialized in France for type 2 diabetes since April 2020 and later for heart and renal diseases. Given the recent developments in treating diabetes and the widening of SGLT-2i indications, we aimed to study changes in the use of glucose-lowering drugs in France and to characterize SGLT-2i new users.

METHODS

We performed a nationwide utilization study using the French health insurance database. Trends in incidence and prevalence of glucose-lowering drug use were assessed by a repeated cross-sectional study in 2019 and 2021. A cohort study of incident SGLT-2i users was then conducted to describe patient characteristics and the strategy for treating diabetes.

RESULTS

The prevalence of SGLT-2i use gradually reached 0.1% in the third quarter of 2021 and increased more significantly to 0.2% thereafter. SGLT-2i became the second most prescribed glucose-lowering drug class after metformin at the end of 2021 (0.1%). Among the cohort of 125 387 SGLT-2i new users (mean age 65.0 years; 60.1% of men), 87.6% presented a diabetic comorbidity. The patient profile changed over the study period with an increasing proportion of patients with cardiovascular (28.7% in 2020 vs. 40.2% in 2021) or renal (7.7% in 2020 vs. 11.8% in 2021) comorbidities at initiation. The main combinations used at SGLT-2i initiation were metformin (12.5%) and metformin plus dipeptidyl peptidase-4 inhibitors (8.1%). One-year probability of SGLT-2i persistence was estimated to be 55%.

CONCLUSION

The expansion of indications for SGLT-2i and the broadening of the target population make it essential to assess the reasons for discontinuation and review their safety profile.

Impact of Glucagon-Like Peptide 1 Agonist Deprescription in Type 2 Diabetes in a Real-World Setting: A Propensity Score Matched Cohort Study

INTRODUCTION

Glucagon-like peptide 1 receptor agonists (GLP-1) elicit substantial reductions in glycemia and body weight in people with type 2 diabetes (T2D) and obesity, but existing data suggest the therapy must be continued indefinitely to maintain clinical improvements. Given the high cost and poor real-world persistence of GLP-1, an effective therapy that enables deprescription with sustained clinical improvements would be beneficial. Thus, the purpose of this real-world study was to assess the effect of GLP-1 deprescription on glycemia and body weight following co-therapy with carbohydrate restricted nutrition therapy (CRNT) supported via telemedicine in a continuous remote care model.

METHODS

A retrospective, propensity score matched cohort study among patients with T2D at a telemedicine clinic was conducted. Patients in whom GLP-1 were deprescribed (DeRx; n = 154) were matched 1:1 with patients in whom GLP-1 were continued (Rx). HbA1c and body weight at enrollment in clinic (pre-CRNT), at date of deprescription or index date (derx/ID), and at 6 and 12 months (m) post-derx/ID were utilized in this study.

RESULTS

No regression in weight was observed following deprescription with > 70% maintaining ≥ 5% weight loss 12 m post-derx/ID. HbA1c rose 6 m and 12 m post-derx/ID in both DeRx and Rx cohorts, but most patients maintained HbA1c < 6.5%. HbA1c and body weight measured 6 m and 12 m following derx/ID did not significantly differ between cohorts and were improved at derx/ID and at follow-up intervals compared to pre-CRNT.

CONCLUSION

These results demonstrate the potential for an alternate therapy, such as CRNT supported via telemedicine, to enable maintenance of weight loss and glycemia below therapeutic targets following discontinuation of GLP-1 therapy.

Euglycemic diabetic ketoacidosis in the era of SGLT-2 inhibitors

Euglycemic diabetic ketoacidosis (EDKA) is an emerging complication of diabetes associated with an increasing use of sodium-glucose transporter type 2 (SGLT-2) inhibitor drugs. This review highlights the growing incidence of EDKA and its diagnostic challenges due to the absence of hallmark hyperglycemia seen in diabetic ketoacidosis (DKA). The paper presents a classification system for the severity of EDKA, categorizing it into mild, moderate, and severe based on serum pH and bicarbonate levels. Another classification system is proposed to define stages of EDKA based on anion gap and ketones at the time of diagnosis and during the treatment period. A treatment algorithm is proposed to guide clinicians in managing EDKA. This treatment algorithm includes monitoring anion gap and ketones to guide insulin and fluid management, and slower transition to subcutaneous insulin to prevent a relapse. Increased awareness of EDKA is essential for a timely diagnosis because an early diagnosis and treatment can improve clinical outcomes.

Real-world national trends and socio-economic factors preference of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists in China

Backgrounds

Robust evidence have demonstrated the beneficial effect of Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) in T2D patients with cardiovascular diseases and chronic kidney disease. Multiple studies analyzed patterns and predictors of SGLT2i and GLP-1RA in the US, Europe and worldwide. However, there is no study about the utilization of these two classes of drugs in real-world in China.

Method

A total of 181743 prescriptions of SGLT2i and 59720 GLP-1RA were retrospectively pooled from Hospital Prescription Analysis Cooperation Project from 2018 to 2021. The social-economic characteristics of patients and prescribers, including age, gender, residency, hospital level, insurance type, department visited, and payment amount, were collected and analyzed to study trends and risk factors associated with preference among two antidiabetics.

Results

Annual number of prescriptions of SGLT2i significantly increased to approximately 140 folds, while GLP-1RA increased to about 6.5 folds. After adjustment for socio-economic information, several patients or physician characteristics were positively associated with the preference of GLP-1RA, including female gender (OR 1.581, 95% CI 1.528-1.635), residents in second-tier cities (OR 1.194, 95% CI 1.148-1.142), visiting primary or secondary hospital level (OR 2.387, 95% CI 2.268-2.512); while other factors were associated with the preference of SGLT2i, including older adults (OR 0.713, 95% CI 0.688-0.739), uncovered by insurance (OR 0.310, 95% CI 0.293-0.329), visiting other departments compared with endocrinology. In addition, the share of SGLT2i and GLP-1RA was low but in an increasing tendency.

Conclusions

SGLT2i and GLP-1RA prescription significantly increased from 2018 to 2021. The socio-economic risk factors in choosing SGLT2i or GLP-1RA highlight an effort required to reduce disparities and improve health outcomes.

Trends in Insulin Types and Devices Used by Adults With Type 2 Diabetes in the United States, 2016 to 2020

IMPORTANCE

Despite rising costs and public scrutiny devoted to insulin, less is known regarding recent trends in its ambulatory use in the United States.

OBJECTIVE

To characterize trends in ambulatory insulin use, overall and based on insulin characteristics, among adults with type 2 diabetes in the United States from January 1, 2016, through December 31, 2020.

DESIGN, SETTING, AND PARTICIPANTS

This serial cross-sectional study included patients whose data were collected in IQVIA's National Disease and Therapeutic Index (NDTI), a 2-stage, all-payer, nationally representative audit of outpatient care. Approximately 4800 physicians each calendar quarter completed a form for 2 consecutive days regarding visits for each of their patients, including diagnoses, treatments, and demographic information. Data were collected from January 2016 through December 2020.

EXPOSURES

Ambulatory use of insulin.

MAIN OUTCOMES AND MEASURES

Nationally representative projections for ambulatory use of insulin (ie, treatment visits), overall and aggregated by insulin molecule (insulins regular, neutral protamine Hagedorn [NPH], lispro, glulisine, glargine, detemir, degludec, and aspart), delivery devices (vials/syringes or pens), therapeutic class (short-acting, rapid-acting, long-acting, intermediate-acting, and premixed insulin), insulin type (human, analog, and biosimilar), and date of approval (newer: before 2010; and older: after 2010).

RESULTS

There were 27 860 691 insulin treatment visits between 2016 and 2020. Among all patient encounters that indicated use of insulin in 2020, 1 989 154 (43.9%) were among those aged 60 to 74 years; 2 372 629 (52.4%) among men; 2 646 247 (58.4%) among White patients; 811 639 (17.9%) among Black patients; and 701 912 (15.5%) among Hispanic patients. Insulin glargine was the most frequently used insulin from 2016 to 2020, accounting for approximately half of treatment visits (eg, 2020: 2.6 of 4.9 million visits; 95% CI, 2.1-3.1 million). Among insulin classes, long-acting insulin accounted for approximately two-thirds of treatment visits during this period (eg, 2020: 3.7 million visits; 95% CI, 3.0-4.4 million). Treatment visits for insulin pens increased from 36.1% in 2016 (2.2 of 6.0 million visits; 95% CI, 1.7-2.7 million) to 58.7% in 2020 (2.9 million visits; 95% CI, 2.3-3.5 million), while use of insulin vials/syringes declined in parallel. Analog insulin use predominated and accounted for more than 80% of total treatment visits across all years (eg, 2020: 4.3 million visits; 95% CI, 3.4-5.1 million). Newer insulins were increasingly used, from 18.1% of total treatment visits in 2016 (1.1 million visits; 95% CI, 0.8-1.4 million) to 40.9% in 2020 (2.0 million visits; 95% CI, 1.5-2.5 million). The use of biosimilar insulin, which was first approved in 2015, increased from 2.6% in 2017 (0.1 of 5.3 million visits; 95% CI, 0.04-0.2 million) to 8.2% in 2020 (0.4 million visits; 95% CI, 0.2-0.6 million) of total insulin treatment visits. The total number of insulin treatment visits declined from a peak of 6.0 million visits in 2016 to a nadir of 4.9 million visits in 2020 (approximately 18% decline).

CONCLUSIONS AND RELEVANCE

In this study, ambulatory insulin use in the United States during the past 5 years remained dominated by the use of insulin analogs and insulin pen delivery devices, with increasing uptake of newer products as they have been brought to market.

Identification of the Inappropriate Clinical Actions (DON'T) to Improve the Management of Patients with Type 2 Diabetes Failing Basal Insulin Supported Oral Treatment: Results of Survey for a Panel of Diabetes Specialists in Italy

INTRODUCTION

Despite the development of several recommendations, glycemic control in a large proportion of patients with type 2 diabetes, including those treated with insulin, remains suboptimal. This study is aimed to identify a set of actions to promote the reduction of inappropriate clinical practices in type 2 diabetes failing basal insulin supported oral therapy (BOT).

METHODS

A panel of diabetes specialists was assembled to identify a list of ten corrective actions, "things not to do," for the management of type 2 diabetes: five concerning treatments, procedures and diagnostic tests and five about relationship, communication and information. The Choosing Wisely methodology and approach were the inspiration.

RESULTS

A total of 73/73 (100%) panelists responded to the survey. Twenty-four actions were proposed. The final list of inappropriate actions deemed most important to improve the management of patients with type 2 diabetes failing BOT were: (1) do not use secretagogues-do not neglect the use of innovative glucose-lowering agents; (2) do not underestimate the risk of lack of hypoglycemia awareness; (3) do not underestimate the benefit of personalization of therapy; (4) do not delay insulin intensification; (5) do not delay modification of the therapeutic regimen. In the area of patient communication, the following actions were identified: (1) do not fail to train in the management of hypoglycemia; (2) do not underestimate whether the patient has understood the modification of therapy; (3) do not prescribe injection therapy without adequately instructing the patient to titrate it; (4) do not ignore the patient's adherence; (5) do not stop listening to the patient and verify learning.

CONCLUSION

A set of corrective experience-based actions to enact in a timely manner, which can assist physicians in improving clinical outcomes and patients' needs in terms of communications and interaction, is proposed. The list is intended to promote discussions among diabetes specialists to provide high-value diabetes care.
