BACKGROUND & AIMS: Malnutrition is common in patients with end-stage liver disease and is a risk factor for post-transplant morbidity. The goal of this study was to assess the safety of an immune-enhancing diet in patients undergoing liver transplantation and to investigate its effects on nutritional status. METHODS: Fifteen consecutive patients received oral Impact (0.6l/d) for a median 54 (range 10-168)d pre-transplant and enteral Impact was started early after transplant. Total body protein was measured prior to commencing supplemental Impact, immediately prior to transplant and 10, 15, 30, 90, and 180 days post-transplant. The results were compared with those from 17 patients who received standard nutritional intervention. RESULTS: All study patients tolerated Impact pre- and postoperatively and there were no safety concerns. Over the preoperative period total body protein increased significantly (P = 0.017). In 7 patients followed for 6 months post-transplant, a significant (P = 0.026) loss of body protein occurred over the first 15 postoperative days which was regained by 6 months. In the patients who did not receive Impact, body protein did not change preoperatively and the loss after surgery was not regained. Infectious complications occurred in 5/15 (33%) Impact patients and 12/17 (71%) non-Impact patients (P = 0.074). CONCLUSIONS: In patients with end-stage liver disease, our results suggest the possibility that Impact may have a role in improving preoperative nutritional status, hastening recovery after transplant, and reducing postoperative infectious complications. These potential benefits need to be confirmed in a randomised controlled trial.
