Clinical Trial Summary

The purpose of this study is to characterise the patient and disease profile under the influence of a protein-restricted diet supplemented with keto acids/amino acids (KA/AA), focusing on the progression of chronic renal insufficiency, calcium and phosphorus metabolism, nutritional status, patient compliance to diet and Ketosteril intake as well as the persistent dietary education to ensure compliance in a large group of pre-dialysis patients.
