Comparison of Antidiabetic Regimens in Patients with Type 2 Diabetes Uncontrolled by Combination Therapy of Sulfonylurea and Metformin: Results of the MOHAS Disease Registry in Korea

Metformin-Insulin versus Metformin-Sulfonylurea Combination Therapies in Type 2 Diabetes: A Comparative Study of Glycemic Control and Risk of Cardiovascular Diseases in Addis Ababa, Ethiopia

OBJECTIVE

This study aimed to compare glycemic control and risk of cardiovascular outcomes of metformin-insulin versus metformin-sulfonylurea combination therapies in type 2 diabetes mellitus.

METHODS

We conducted a comparative cross-sectional study in five tertiary level hospitals in Addis Ababa, Ethiopia. We enrolled 321 patients with type 2 diabetes mellitus who were on continuous treatment follow-up on either metformin-insulin or metformin-sulfonylurea combination therapy. We interviewed the participants and reviewed their medical records to investigate medication efficacy, safety, and adherence. The primary outcome measure was glycemic control and the secondary outcome measures were composite cardiovascular outcomes.

RESULTS

Of the total participants enrolled, 50.5% (n = 162) were those who received metformin-insulin and 49.5% (n = 159) metformin-sulfonylurea combination therapies for a median of 48 months follow-up. The reduction of Hb1Ac levels was comparable between the metformin-insulin (-1.04 ± 0.96%) and metformin-sulfonylurea (-1.02 ± 1.03%), p = 0.912. Patients who received metformin-sulfonylurea had 4.3 times more likely to have achieved target HbA1c level compared to those who received metformin-insulin, p < 0.001, adjusted odds ratio (AOR) with 95% CI = 4.31[1.79-10.32]. Risk of composite cardiovascular outcomes was higher in metformin-insulin group (40.5% versus 34.0%), p = 0.021. Co-morbidities, body mass index, systolic blood pressure, and HbA1c had a significant association with composite cardiovascular outcomes. Reductions of bodyweight, HDL-C, LDL-C, triglycerides levels, and microvascular complications were different between the two groups, p < 0.05.

CONCLUSION

High proportion of patients who received metformin-sulfonylurea achieved target HbA1c level and had less composite cardiovascular outcomes compared to those who received metformin-insulin. However, these findings have to be confirmed with randomized control trials to determine risks associated with insulin use, while efficacy is maintained as second-line treatment in patients with type 2 diabetes mellitus.

Insulin therapy for adult patients with type 2 diabetes mellitus: a position statement of the Korean Diabetes Association, 2017

The Korean Diabetes Association (KDA) has regularly updated its Clinical Practice Guidelines. In 2017, the KDA published a position statement on the use of antihyperglycemic agents for patients with type 2 diabetes mellitus (T2DM). Growing evidence from new multinational clinical trials using novel and traditional insulin analogues has also been accumulated. Following global trends, many results of clinical trials, especially concerning the clinical efficacy and safety of insulin therapy, have been published about Korean patients with T2DM. After a systematic search of recent evidence, the KDA updated and modified its clinical practice recommendations regarding the initiation, choice, and intensification of insulin and created an insulin treatment algorithm for the first time to guide physicians caring for adult Korean patients with T2DM.

Antihyperglycemic agent therapy for adult patients with type 2 diabetes mellitus 2017: a position statement of the Korean Diabetes Association

In 2017, the Korean Diabetes Association (KDA) published a position statement on the use of antihyperglycemic agents for patients with type 2 diabetes mellitus (T2DM). The KDA regularly updates its Clinical Practice Guidelines, but since the last update in 2015, many results from clinical trials have been introduced, and domestic data from studies performed in Korean patients with T2DM have been published. Recently, evidence from large clinical studies assessing cardiovascular outcomes following the use of sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists in patients with T2DM were incorporated into the recommendations. Additionally, new data from clinical trials using dipeptidyl peptidase 4 inhibitors and thiazolidinediones in Korean patients with T2DM were added. Following a systematic review and assessment of recent evidence, the KDA updated and modified its clinical practice recommendations regarding the use of antihyperglycemic agents and revised the treatment algorithm for Korean adult patients with T2DM.
