A recent study by researchers at UT Southwestern Medical Center suggests that popular weight-loss drugs, which are already used to manage type 2 diabetes, could also help reduce complications and mortality rates in patients suffering from chronic kidney disease (CKD). The findings highlight the potential of glucagon-like peptide-1 receptor agonists (GLP1-RAs), including semaglutide, liraglutide, and dulaglutide, in improving the outcomes for individuals with diabetes-related kidney conditions.
GLP1-RAs, commonly prescribed to manage blood sugar levels, were found to provide three key benefits to patients with diabetes-induced kidney disease: reducing hospitalizations, lowering all-cause mortality, and slowing the progression of kidney disease. This marks an important development in the field, offering new hope to a high-risk population that often faces limited treatment options.
“Our research provides much-needed evidence supporting the renal-protective effects of GLP1-RAs, particularly for patients with moderate to advanced CKD,” explained Dr. Shuyao Zhang, Assistant Professor of Internal Medicine at UT Southwestern and the first author of the study. Dr. Zhang worked alongside co-senior authors Dr. Ildiko Lingvay and Dr. Ishak A. Mansi, who have extensive expertise in the area.
Published in Nature Communications, the study employed a robust approach, analyzing medical records from a nationwide cohort of 64,705 veterans with both diabetes and CKD. Researchers compared two groups: one receiving GLP1-RAs and the other receiving dipeptidyl peptidase-4 inhibitors (DPP4is), a common alternative. The study aimed to ensure that both groups had comparable baseline characteristics.
Over nearly two years of data analysis, GLP1-RA-treated patients showed significant improvements. Hospitalizations were 10% lower, all-cause mortality was reduced by 16%, and the progression of kidney disease was slowed by 36% when compared to those treated with DPP4is.
Patients with CKD related to type 2 diabetes are particularly vulnerable to serious health complications, including hypoglycemia, infections, and cardiovascular events. Effective management of these risks has proven difficult, with many individuals requiring frequent hospitalizations. “People with diabetes and chronic kidney disease are at high risk for complications and hospitalizations,” noted Dr. Lingvay, a co-senior author on the study. “Our findings suggest that GLP1-RAs can significantly reduce cardiovascular events, slow kidney disease progression, and lower healthcare costs—offering tangible benefits for these patients.”
This research could influence clinical practices, offering a new avenue for managing diabetic kidney disease. Dr. Zhang emphasized that diabetic kidney disease has historically been challenging to treat, but with further studies, guidelines could evolve to include GLP1-RAs as a key part of comprehensive treatment plans for these patients. Such changes could significantly improve long-term health outcomes and quality of life.
Dr. Lingvay, who has extensively studied semaglutide’s impact on cardiovascular health and weight management, believes these medications could become essential tools in addressing diabetic kidney disease. “These medications have proven benefits, and our study underlines their potential to improve outcomes for a vulnerable patient population,” she said.
The research underscores a promising new chapter in the treatment of chronic kidney disease, especially for those affected by diabetes, providing a new strategy for clinicians to consider in their approach to managing this complex condition.
