TOPLINE:
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are associated with a lower risk for sight-threatening retinopathy than other second-line glucose-lowering medications in patients with type 2 diabetes (T2D).
METHODOLOGY:
- Researchers conducted a nationwide cohort study including 3,544,383 patients with newly diagnosed T2D.
- During the 5-year study period, 159,965 patients were treated with SGLT2 inhibitors, 304,383 received dipeptidyl peptidase-4 (DPP-4) inhibitors, 108,420 took pioglitazone, and 189,618 received sulfonylurea.
- The propensity score matching found 65,930 pairs of patients treated with SGLT2 inhibitors vs DPP-4 inhibitors, 93,760 pairs treated with SGLT2 inhibitors vs pioglitazone, and 42,121 pairs treated with SGLT2 inhibitors vs sulfonylurea.
- The main outcome was sight-threatening retinopathy in patients with at least two outpatient visits or one hospitalization or anti-vascular endothelial growth factor injections.
TAKEAWAY:
- SGLT2 inhibitors reduced sight-threatening retinopathy risk by 43% vs DPP-4 inhibitors (adjusted hazard ratio [aHR], 0.57), 38% vs sulfonylurea (aHR, 0.62), and 25% vs pioglitazone (aHR, 0.75; P < .001 for all).
- Similarly, the cumulative incidence of sight-threatening retinopathy was significantly lower with SGLT2 inhibitors vs DPP-4i, pioglitazone, or sulfonylurea (P < .001 for all).
- All three SGLT2 inhibitor treatments, namely, empagliflozin, dapagliflozin, and canagliflozin, were more effective than DPP-4 inhibitors, pioglitazone, or sulfonylurea in reducing the risk for sight-threatening retinopathy.
IN PRACTICE:
“SGLT2i treatments were as safe and effective in slowing the progression of diabetic retinopathy as in lowering the risk for diabetic nephropathy in patients with T2D,” the authors wrote.
SOURCE:
This study was led by Fu-Shun Yen, MD, a private practitioner from Taiwan, and was published online on December 20, 2023, in JAMA Network Open.
LIMITATIONS:
There were insufficient data regarding the participants’ alcohol use, physical activity, smoking status, and family history, which may have had an impact on the results.
The study mainly involved individuals of Taiwanese ethnicity.
DISCLOSURES:
This study was supported partly by the Taiwan Ministry of Health and Welfare Clinical Trial Center, the MOST Clinical Trial Consortium for Stroke, and other sources. The authors declared no conflicts of interest.
