Intradialytic parenteral nutrition in malnourished patients with chronic kidney disease: a systematic review

Introduction: Malnutrition is a prevalent condition among patients with chronic kidney disease (CKD). Objective: To answer the question of the effect of intradialytic parenteral nutrition (IPN) on malnourished CKD patients undergoing dialysis, a systematic review of clinical trials was performed. Methods: The systematic review was performed according with PRISMA. The review was carried out between September and October 2022. The search strategy included PubMed, Web of Science and LILACS databases. The selection of articles was carried out using the Rayyan platform and to assess the chance of bias, the Rob2 instrument recommended by Cochrane was employed. Results and Conclusions: From 762 article retrieved in the initial strategy only 4 articles were included in the review. In a general view, the use of IPN increased the levels of prealbumin and albumin in the participants. Studies evaluating this topic are sparse. More studies are needed to recommend the use of IPN universally in the context of malnourished patients with CKD.
