Creatinine Index as a Surrogate of Lean Body Mass Derived from Urea Kt/V Pre-Dialysis Serum Levels and Anthropometric Characteristics of Haemodialysis Patients

摘要

Background and ObjectivesProtein-energy wasting is common in long-term haemodialysis (HD) patients with chronic kidney disease and is associated with increased morbidity and mortality. The creatinine index (CI) is a simple and useful nutritional parameter reflecting the dietary skeletal muscle protein intake and skeletal muscle mass of the patient. Because of the complexity of creatinine kinetic modeling (CKM) to derive CI, we developed a more simplified formula to estimate CI in HD patients.
