Description
INTRODUCTION: Over 500,000 Americans have End-Stage Renal Disease (ESRD) and are on hemodialysis, which serves as a risk factor for many different complications. One notable example is protein energy wasting (PEW) where the body’s protein and energy storage are low. Oral supplementation is the first line for PEW, and IDPN should only be used if oral supplementation is not effective or intolerable. Objective: To conduct a PubMed search of the current literature on studies focused on IDPN and its efficacy in hemodialysis patients.
METHOD: A structured literature search of PubMed using the terms “intradialytic parenteral nutrition”. The filters applied included: Results by Year from 2006 to 2026; article types: Clinical Study, Clinical Trial, Multicenter study, Observational Study, and Randomized Controlled Trial; article language of English; and studies of human species. Studies were included if they evaluated the efficacy or clinical outcomes of IDPN in hemodialysis patients. Studies were excluded if they did not isolate IDPN as the primary intervention or did not assess efficacy or clinical outcomes related to IDPN administration.
RESULTS: Initial search showed 14 results, but only 10 studies were included; 4 were excluded. Overall, evidence suggests that IDPN can improve nutritional parameters in malnourished hemodialysis patients compared to baseline or standard care. However, findings on long term clinical outcomes, including mortality and hospitalization, were inconsistent. IDPN was generally well tolerated with no major safety concerns reported across studies.
DISCUSSION/CONCLUSION: IDPN appears to be an effective adjunct therapy for improving nutritional status in hemodialysis patients with PEW who are unable to meet their needs through oral supplementation alone. While short term nutritional benefits are evident, its impact on long term clinical outcomes remains unclear. Further large scale, well designed randomized controlled trials are needed to better define its role in clinical practice.
