Abstract:
Sodium-glucose cotransporter-2 (SGLT2) inhibitors have emerged as a promising therapy for diabetes and CKD patients. However, the pros and cons of SGLT2i in Type2 diabetes patients with CKD stage 5 remained largely unexplored. By using Taiwan's national health insurance research database (NHIRD), this observational cohort study enrolled T2DM patients with newly identified as having CKD5, and the index date defined as the date of CKD5 identification. The enrollees were divided into 2 groups depending on whether SGLT2 inhibitors were used for more than 3 months or not following the index date. A 1:4 propensity score matching was performed to balance characteristics between two groups. The SGLT2-inhibitor group exhibited significantly lower risks of new-onset ESRD (35.9% vs. 58.2%, hazard ratio [HR] 0.59, 95% confidence interval [CI]: 0.59-0.74). For the risks of MACCEs (16.72% vs. 17.66%, HR 0.84, 95% CI: 0.62-1.15), infections related hospitalization (2.4% vs. 2.61%, HR:1.02, 95% CI:0.80-1.31), Infection-associated mortality (3.45% vs. 4.18% HR:0.80, 95% CI:0.41-1.56) and all-cause mortality (13.79% vs. 13.83%, HR:0.95, 95% CI:0.68-1.32), no significant differences were observed between two groups. In conclusion, we provide evidence suggesting that SGLT2 inhibitors may offer renal protection and did not increase infection risks for CKD5 patients with type2 diabetes.
Insights
Sodium-glucose cotransporter-2 (SGLT2) inhibitors significantly reduced end-stage renal disease risk in type 2 diabetes patients with advanced chronic kidney disease (CKD5). SGLT2 inhibitors did not increase risks for major adverse cardiovascular events or mortality in this population.
Area of Science:
- Nephrology
- Endocrinology
- Pharmacology
Background:
- Sodium-glucose cotransporter-2 (SGLT2) inhibitors are recognized for their benefits in diabetes and chronic kidney disease (CKD).
- The specific impact of SGLT2 inhibitors on patients with type 2 diabetes (T2DM) and advanced CKD (CKD stage 5) requires further investigation.
Purpose of the Study:
- To evaluate the efficacy and safety of SGLT2 inhibitors in T2DM patients diagnosed with CKD stage 5.
- To assess the effect of SGLT2 inhibitors on the risk of end-stage renal disease (ESRD) and other adverse outcomes.
Main Methods:
- An observational cohort study utilizing Taiwan's National Health Insurance Research Database (NHIRD).
- T2DM patients newly identified with CKD5 were propensity score matched (1:4) into SGLT2 inhibitor users and non-users.
- Outcomes including new-onset ESRD, major adverse cardiovascular events (MACCEs), infection-related hospitalizations, and mortality were compared.
Main Results:
- SGLT2 inhibitor use was associated with a significantly lower risk of new-onset ESRD (HR 0.59, 95% CI: 0.59-0.74).
- No significant differences were found in the risks of MACCEs, infection-related hospitalizations, infection-associated mortality, or all-cause mortality between the groups.
Conclusions:
- SGLT2 inhibitors demonstrate renal protective effects in T2DM patients with CKD stage 5.
- SGLT2 inhibitors appear safe for use in this population, without an increased risk of cardiovascular events or infections.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
