Correction to: “Cardiovascular Outcomes Comparison of Dipeptidyl Peptidase-4 Inhibitors Versus Sulfonylurea as Add-on Therapy for Type 2 Diabetes Mellitus: A Meta-Analysis”

ABSTRACT:

Objective

Recent studies have raised concerns about the cardiovascular safety of dipeptidyl peptidase-4 (DPP4) inhibitors. We performed a systematic review and meta-analysis to compare the cardiovascular outcomes of sulfonylureas (SUs) versus DPP4 inhibitors in combination with metformin.

Methods

After searching for trials using combination therapy of metformin with an SU or DPP4 inhibitor in PubMed, Cochrane Library, and Embase, 1 prospective observational study and 15 randomized controlled studies were selected.

Results

Regarding the primary analysis endpoint, no significant differences were found in the risk of all-cause mortality between SUs and DPP4 inhibitors as add-on therapies to metformin (random-effect relative risk [RR], 1.14; 95% confidence interval [CI], 0.98–1.33; I2=0%; p=0.097). Cardiovascular death was also similar between SUs and DPP4 inhibitors in the 5 studies that reported outcomes (random-effect RR, 1.03; 95% CI, 0.83–1.27; I2=0%; p=0.817). Furthermore, there were no significant differences in major adverse cardiac events, coronary heart disease, myocardial infarction, and heart failure. However, the SU group showed a higher risk of ischemic stroke, more hypoglycemic events, and more weight gain than the DPP4 inhibitor group (ischemic stroke, random-effect RR, 2.78; 95% CI, 1.06–7.30; I2=51.9%; p=0.039; hypoglycemia, random-effect RR, 3.79; 95% CI, 1.53–9.39; I2=98.2; p=0.004; weight gain, weighted mean difference, 1.68; 95% CI, 1.07–2.29; I2=94.7; p<0.001).

Conclusion

As add-on therapies to metformin, SUs and DPP4 inhibitors showed no significant differences in all-cause mortality and cardiovascular mortality. However, some of the favorable results of DPP4 inhibitors suggest good safety and feasibility of the drugs.

Project description:IntroductionNo study has compared the effects of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and dipeptidyl peptidase 4 inhibitors (DPP4is) on patients' quality-of-life (QOL).MethodsWe enrolled 253 drug-naïve Japanese patients with type 2 diabetes mellitus (T2DM), randomly assigned them into a dapagliflozin (SGLT2i) group or DPP4i group in approximately 1:1 ratio, and monitored them for 24 weeks. The primary endpoint was the proportion of subjects indicating improvement in the "overall quality of life" domain of SHIELD-WQ-9 at week 24. Secondary endpoints included other domains of SHIELD-WQ-9, DTR-QOL, EQ-5D-5L, medication preference, medication adherence, diet therapy adherence, body weight, body mass index (BMI), abdominal circumference, HbA1c, and frequency of adverse events.ResultsThe proportion of subjects indicating improvement in the "overall quality of life" domain of SHIELD-WQ-9 at week 24 was higher in the dapagliflozin group (28.4%) than in the DPP4i group (18.6%) (p = 0.08). The proportion of subjects indicating improvement in the "physical health" domain of SHIELD-WQ-9 at week 24 was significantly higher in the dapagliflozin group (42.2%) than in the DPP4i group (23.7%) (p = 0.004). Total scores and domain 1 scores of DTR-QOL showed greater improvement in the dapagliflozin group (14.3 ± 15.6 and 15.5 ± 20.8, respectively) than in the DPP4i group (10.2 ± 15.6 and 10.3 ± 19.5, respectively) (both p = 0.05). EQ-5D-5L scores had significantly improved in the DPP4i group (0.023 ± 0.088) (p = 0.005); the intergroup difference was not significant (p = 0.14). Body weight (p < 0.001), BMI (p < 0.001), and abdominal circumference (p = 0.019) had significantly decreased in the dapagliflozin group compared with the corresponding values in the DPP4i group.ConclusionDapagliflozin showed a comparable or more favorable benefit on Japanese patients' QOL compared with DPP4is. Dapagliflozin was well tolerated. It significantly reduced body weight, which was significantly correlated with improvement in the patients' QOL. This study demonstrates that dapagliflozin can be used as a first-line drug for T2DM in Japan with a beneficial impact on patients' QOL.Trial registrationUniversity Hospital Medical Information Network Clinical Trial Registry (UMIN000030514); Japan Registry of Clinical Trials (jRCTs051180165).

Project description:AbstractThe comparative effectiveness of oral hypoglycemic agents on glycemic control and chronic complications in clinical practice is unknown in Korea. This study aimed to compare glycemic control and the incidence of hypoglycemia and chronic complications among adult patients with type 2 diabetes prescribed metformin, dipeptidyl peptidase-4 inhibitors (DPP4I), and sulfonylurea (SU) as monotherapy or dual combination therapy.We retrospectively analyzed propensity-matched cohort data from 3 national university hospitals in Korea. All electronic health records were transformed into a unified Observational Medical Outcomes Partnership Common Data Model and analyzed using ATLAS, an open-source analytical tool, and R software. Glycemic control was assessed as the first observation of a reduction in glycosylated hemoglobin (HbA1c) level below 7% after prescription of the drug. Differences in the incidence of chronic complications were compared based on the first observation of each complication. Glycemic control and chronic complications were evaluated in patients who maintained the same prescription for at least 3 and 12 months, respectively.Patients who received metformin had lower hazard of reaching HbA1c levels below 7% as compared with those who received SU, and had higher hazard compared with those who received DPP4I (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.75-0.98; and HR, 1.68; 95% CI, 1.42-1.99, respectively). The incidence of hypoglycemia was significantly higher in the SU group than in the metformin and DPP4I groups (metformin vs SU; HR, 0.30; 95% CI, 0.21-0.43; SU vs DPP4I; HR, 4.42; 95% CI, 2.35-8.31). Metformin + DPP4I had similar hazard of reaching HbA1c levels below 7% compared with metformin + SU (HR, 1.19; 95% CI, 0.99-1.43) and the incidence of hypoglycemia was significantly lower in the metformin + DPP4I group (HR 0.13; 95% CI 0.05-0.30). There was no significant difference in the analysis of the occurrence of chronic complications.SU followed by metformin was effective, and both drugs showed an increased hazard of reaching HbA1c levels below 7% compared with DPP4I. Metformin + DPP4I is comparatively effective for HbA1c level reduction below 7% compared with metformin + SU. Hypoglycemia was high in the SU-containing therapy.
