Study Summary

This is a prospective multicenter randomized controlled trial with a total duration of 36 months aiming to evaluate the effectiveness and the safety of low protein diet on top of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and renin-angiotensin-aldosterone inhibitors (RAASi) in reducing the progression of chronic kidney disease in patients with type 2 Diabetes Mellitus

Study Description

The KDIGO Diabetes in CKD Guideline (2020) recommends the use of SGLT2i (level 1A) and suggests (level 2C) the prescription of plant protein-based low-protein diet in patients with chronic kidney disease (CKD) and diabetes mellitus (DM). Both interventions have shown synergistic nephroprotective effects, slowing the progression of chronic kidney disease by reducing glomerular hyperfiltration and proteinuria, thus resulting the hypothesis that by combining these two interventions it could be possible to achieve a superior control over the progression of diabetic kidney disease.

The nutritional intervention will consist in a mild protein restriction (0.6 g/kg dry ideal body weight) and a total recommended energy intake of 30-35 kcal/kg of ideal dry body weight per day in all patients. The protein intake will be checked through the food diary and calculated based on urea from 24 hours urine collection.

The efficacy and safety parameters will be evaluated during follow-up visits at month 1,2,3,6,12 and 18.
