[Anti-Proteinuric Effect of GLP1-RA as Add-On to SGLT2-i and ACE-i in a Diabetic Patient with IgA Nephropathy].

Abstract

Immunoglobulin A (IgA) nephropathy is a common glomerulonephritis, but its treatment remains matter of debate. Recommendation for corticosteroids has been supported, but renin-angiotensin inhibitors, RAAS, and sodium-glucose co-transporter 2 inhibitors (SGLT2i) are increasingly used because of a better benefit/safety balance in comparison with systemic steroids and immunosuppressive treatments. In this case report, a patient with type 2 diabetes (T2DM) and biopsy-proven nephrotic IgA-related nephropathy documented a rapid meaningful reduction of proteinuria and the effect was persistent for 2 years, after receiving the treatment with a GLP1-RA on top of the previous treatment with ACE-inhibitors and SGLT2-i. Considering the beneficial effects of GLP1-RA in diabetes related chronic kidney disease, the present case report supports the notion that these drugs could also represent a beneficial treatment option in IgA nephropathy.
