What nPCR is recommended for hemodialysis patients?

KDOQI recommends nPCR ≥1.0 g/kg/day for clinically stable hemodialysis patients. Low nPCR suggests inadequate protein intake or malnutrition, while high nPCR may indicate excessive protein catabolism.

Is PCR the same as dietary protein intake?

In stable patients, PCR approximates dietary protein intake (DPI). In catabolic states, PCR may exceed DPI due to breakdown of endogenous proteins, so clinical context is essential for interpretation.

Calculate Protein Catabolic Rate (PCR) and normalized PCR (nPCR) in hemodialysis patients from interdialytic BUN change and urine urea excretion to assess protein intake and nutritional status.
