Application of individualized low-protein diet nursing for managing multiple myeloma patients with renal impairment

Abstract

This study evaluates the effectiveness of individualized low-protein diet (ILPD) nursing in patients with multiple myeloma (MM) complicated by renal impairment. A total of 126 MM patients with renal impairment admitted between August 2023 and July 2024 were retrospectively analyzed. Patients received either ILPD nursing (ILPD, n = 64) or routine diet nursing (control, n = 62). Nutritional status, renal function, inflammation, quality of life, and adverse events were compared between groups. After 1 year, the ILPD group showed improved albumin levels, stable body mass index, better renal function, reduced C-reactive protein, and higher quality of life scores, with fewer adverse events compared to controls. ILPD nursing significantly benefits renal function, nutrition, and quality of life while reducing adverse events in MM patients with renal impairment, representing a feasible and effective management strategy.
