GLP-1 Receptor Agonist Therapy in Adults With Sickle Cell Disease and Type 2 Diabetes: A Real-World Cohort Analysis

Nguefang GL, Boateng S, Gyabaah S, Issaka Y, Konlack JG, Landa EL, Eze E, Njei B

Summary

This real-world study of 1,391 matched patients with sickle cell disease (SCD) and type 2 diabetes found that GLP-1 receptor agonist therapy was associated with a 39% reduction in major adverse cardiovascular events (HR 0.61), 53% reduction in stroke risk (HR 0.47), and 36% reduction in vaso-occlusive crises (HR 0.64) over 12 months. There was no increased risk of hypoglycemia compared to controls.

Clinical Significance

First large-scale evidence supporting GLP-1 RA use in the high-risk SCD+T2DM population, demonstrating cardiovascular and vaso-stabilizing benefits beyond glycemic control. This opens a new therapeutic window for peptide therapy in hematological disorders where treatment options are limited.
