Summary

Diabetic kidney disease (DKD) is one of the most life-threatening complications of diabetes and a leading cause of chronic kidney disease. Glucagon-like peptide 1 receptor agonists (GLP1-RAs) or sodium-glucose cotransporter 2 inhibitors (SGLT2is) appear to improve renal outcome in patients with Type 2 diabetes (T2D). In this context, the renal resistive index (RRI) is a useful doppler measure to study DKD and predict its evolution. The aim of this work was to study the effect of treatment with GLP1-RA or SGLT2i on RRI and the relationship between RRI and glycometabolic parameters. One hundred forty-five patients with T2D were enrolled in the study and treated for 26 weeks with once-weekly GLP1-RA (38 patients with dulaglutide and 39 with semaglutide), SGLT2i (40 patients), or other therapies (28 control patients). Clinical, anthropometric, and hematochemical parameters and RRI were measured at baseline (T0) and after 6 months of treatment (T6). Changes at 6 months were studied and compared by treatment group. Patients were predominantly male (58.6%), overweight (93.0%) or frankly obese (60.0%), with hypertension (90.0%) and high (> 0.64) or pathological (> 0.7) RRI values (82.0% or 37.0%, respectively). At baseline, RRI correlated positively with age, fasting blood glucose, glycated hemoglobin (HbA1c), triglycerides, and albuminuria and negatively with estimated-glomerular filtration rate (e-GFR). At T6, patients treated with either GLP1-RA or SGLT2i showed a significant improvement in RRI but not in albuminuria or e-GFR, compared with homologous at baseline. In particular, RRI normalized in 32% and 30% of patients on therapy with GLP1-RA and SGLT2i, respectively, while remaining almost unchanged in controls. Notably, the RRI improvement was independent of age, gender, diabetes duration, and changes in BMI, waist circumference, HbA1c, and e-GFR. In conclusion, RRI can be used to detect early kidney damage and follow the evolution of DKD. GLP1-RA and SGLT2i improve RRI, demonstrating benefits on cardiovascular risk and renal outcomes.
