摘要
Objective: Malnutrition is common in hemodialysis (HD) patients and is a powerful predictor of morbidity and mortality. While much progress has been made in identifying the causes and pathogenesis of malnutrition in patients on HD, no consensus has been reached on its management. Nutritional counseling, appetite stimulants, growth hormone, androgenic anabolic steroids, and anti-inflammatory drugs have been tested with contradictory and nonconclusive results. Oral nutritional supplements (ONSs) and intradialytic parenteral nutrition (IDPN) also have been studied.
Design/Setting/Patients: We searched the MEDLINE and PubMed databases for randomized clinical trials, comparative nonrandomized clinical trials, studies with patients who were controls for themselves, and single-arm studies on ONS and IDPN. Thirty-four studies (3223 patients) have been identified and analyzed. Seventeen studies were on ONS (778 patients) and 17 were on IDPN (2475 patients).
Results: ONS may improve serum albumin levels and/or other nutritional parameters, whereas there are insufficient data on clinical outcome. IDPN improves serum albumin and body weight.
Conclusion: Data on survival are conflicting but the only study with an adequate population sample shows that IDPN does not influence survival. Randomized, controlled studies are needed to clarify the role of ONS and IDPN in the treatment of malnutrition in HD.
