Minimal Change Podocytopathy with Coexistent Thin Glomerular Basement Membrane following Exposure to Semaglutide.

Abstract

Introduction: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are FDA-approved for weight loss and are increasingly prescribed for patients with obesity and type 2 diabetes mellitus. Multiple studies have demonstrated desirable renal and cardiovascular benefits from these novel agents. So far, a few case reports of acute tubular injury and acute interstitial nephritis have been reported with GLP-1RA. Podocytopathies in association with semaglutide are rare. In this case report, we present a case of nephrotic syndrome that developed after exposure to semaglutide and propose potential pathophysiological mechanisms underlying this rare renal complication.

Case presentation: Herein, we report a novel case of a 43-year-old female who was evaluated in the nephrology clinic for abrupt onset of bilateral lower extremity edema and foamy urine, a few weeks after exposure to semaglutide. She was diagnosed with nephrotic syndrome and subsequently underwent a kidney biopsy, which revealed features suggestive of minimal change disease, along with coexistent thin basement membrane disease.

Conclusion: GLP-1RAs have been increasingly prescribed due to their proven pleiotropic benefits, including improvements in albuminuria, glycemic control, weight loss, and cardioprotective effects. Despite the considerable benefits of GLP-1RAs, it is essential to recognize novel side effects.
