Effect of Teneligliptin versus Sulfonylurea on Major Adverse Cardiovascular Outcomes in People with Type 2 Diabetes Mellitus: A Real-World Study in Korea

Association between age at diagnosis of type 2 diabetes and cardiovascular morbidity and mortality risks: A nationwide population-based study

AIMS

We aimed to investigate the association between the age at diagnosis of type 2 diabetes and the risk of cardiovascular (CVD) outcomes in comparison with nondiabetic counterparts.

METHODS

A total of 634,350 patients with newly diagnosed type 2 diabetes between January 1, 2012, and December 31, 2014 were included in a Korean population cohort study. Nondiabetic matched controls were selected from the general population in a 1:2 ratio. Participants were followed until the end of 2019 for CVD outcomes and mortality.

RESULTS

During 5.7 years of follow-up, patients with type 2 diabetes diagnosed at ≤40 years of age had the highest excess risk for most outcomes relative to controls, with an adjusted hazard ratio (HR) (95 % CI) of 6.08 (5.51-6.70) for total mortality, 7.10 (6.66-7.58) for hospitalization for heart failure, and 5.04 (4.86-5.24) for coronary heart disease. All risks attenuated progressively with each increasing decade of diagnostic age.

CONCLUSION

In this population-based cohort study, a younger age at diagnosis of type 2 diabetes was associated with a higher relative risk of mortality and CVD outcomes. Therefore, primary prevention of type 2 diabetes is desirable at all ages but is particularly important at younger ages.

Finding the most cost-effective option from commonly used Dipeptidyl peptidase-4 inhibitors in India: a systematic study

OBJECTIVE

To identify a preferred and cost-effective drug among Dipeptidyl peptidase-4 inhibitors (DPP4Is) for Indian patients with T2DM.

METHODS

We performed a systematic literature search using standard databases for relevant literature. Original studies comparing the efficacy and/or safety of different DPP4Is were included. Two authors independently performed the literature search, screening, and collected relevant data from the selected studies. The costs of all brands of individual DPP4Is were noted and compared for lowest, highest, and average cost. Finally, we summarized the information with respect to Efficacy, safety, suitability, and cost to find the most cost-effective DPP4I.

RESULTS

We found 13 eligible studies containing data on 15,720 subjects. These studies showed similar efficacy (or better) and safety with teneligliptin as compared to other DPP4Is. Teneligliptin also showed additional benefits other than the glycemic control. The average cost per tablet of teneligliptin 20 mg was markedly lower as compared to sitagliptin, vildagliptin, and other commonly used DPP4Is. Teneligliptin also outscored other commonly used DPP4Is in India in suitability and seems to have better patient compliance.

CONCLUSIONS

Teneligliptin 20 mg could be considered as the preferred and most cost-effective agent among commonly used DPP4Is for the effective management of patients with T2DM in India.

Systematic review and meta-analysis of teneligliptin for treatment of type 2 diabetes

BACKGROUND AND AIM

There are efficacy and safety concerns related to teneligliptin treatment. A systematic review of randomized controlled trials (RCTs) was undertaken to comprehensively profile the efficacy and safety of teneligliptin in the treatment of type 2 diabetes mellitus (T2DM).

METHODS

Thirteen studies were chosen from a search of scientific databases for RCTs using teneligliptin as a monotherapy or as an adjunct to other glycemic agents with pre-specified inclusion criteria. We calculated weighted mean differences (WMDs) and 95% confidence intervals (CIs) in each included trial and pooled the data using a random-effects model.

RESULTS

Thirteen studies enrolled 2853 patients were identified. Teneligliptin treatment was associated with weight gain (vs. placebo, weighted mean difference (WMD) 0.28 kg; 95% CI - 0.20-0.77 kg; I² = 86%; P = 0.25). Compared to monotherapy, add on therapy with teneligliptin showed significant improvement in FPG mg/dl levels (WMD - 16.75 mg/dl; 95% CI - 19.38 to - 14.13 mg/dl), HOMA-β (WMD 7.91; 95% CI 5.38-10.45) and HOMA-IR (WMD - 0.27; 95% CI - 0.46 to - 0.07). The improvement in HbA1c was greater with monotherapy (WMD - 8.88 mmol/mol; 95% CI - 9.59 to - 8.08 mmol/mol). There was no significant risk of any hypoglycemia with teneligliptin compared to placebo (OR 0.84; 95% CI 0.44-1.60; I² = 0%; P = 0.60). However, the risk was 1.84 times high when combined with other glycemic agents. The risk of cardiovascular events was comparable, regardless of treatment duration when compared to placebo or any other active comparator (OR 0.79; 95% CI 0.40-1.57; I² = 0%; P = 0.50). [PROSPERO, CRD42022360785].

CONCLUSIONS

Teneligliptin is an effective and safe therapeutic option for patients with T2DM, both as monotherapy and as add-on therapy. However, additional large-scale, high-quality, long-term follow-up clinical trials with diverse ethnic populations are required to confirm its long-term efficacy and safety.

Association Between DPP4 Inhibitor Use and the Incidence of Cirrhosis, ESRD, and Some Cancers in Patients With Diabetes

CONTEXT

There are relatively few data on noncardiovascular (non-CV) long-term clinical outcomes of dipeptidyl peptidase 4 inhibitor (DPP4i) treatment.

OBJECTIVE

We aimed to evaluate some non-CV effects of DPP4is in patients with diabetes.

METHODS

Based on data from the National Health Insurance Service database in Korea (2007-2018), we conducted 3 pairwise comparisons of metformin-combined antidiabetic therapies in adult patients with diabetes: DPP4is vs (1) all other oral antidiabetic agents, (2) sulfonylureas/glinides, and (3) thiazolidinediones (TZDs). Major outcomes were liver cirrhosis, end-stage renal disease (ESRD), and cancers in the liver, kidney, and pancreas. Adjusted hazard ratios (HRs) and 95% CIs for the outcomes were estimated using an adjusted Cox model.

RESULTS

Of the 747 124 patients included, 628 217 had received DPP4i therapy for a mean duration of 33.8 ± 25.0 months. Compared with TZD therapy, DPP4i therapy was associated with higher adjusted HRs [95% CIs] for liver cirrhosis (1.267 [1.108-1.449]), ESRD (1.596 [1.139-2.236]), liver cancer (1.117 [1.011-1.235]), and pancreatic cancer (1.158 [1.040-1.290]). Furthermore, apart from liver cirrhosis, a higher risk of each of these outcomes was associated with DPP4i use than with non-DPP4i use. The higher adjusted HRs associated with DPP4i use further increased when patients with long-term exposure to DPP4is were analyzed.

CONCLUSION

DPP4i therapy in patients with diabetes was associated with a higher risk of liver cirrhosis and cancer, ESRD, and pancreatic cancer than TZD therapy and, except for liver cirrhosis, the risk of these outcomes was greater with DPP4i treatment than with non-DPP4i treatment.
