Abstract

Background: Immunosuppressive drugs continue to pose significant risks such as infection, toxicity, or neoplasia when used in long-term therapy. The investigation of newer and safer combined treatment strategies that decrease the need for these drugs is becoming increasingly important. Immunonutrients are known to have significant modulating effects on the immune system. Feeding with Impact, a commercially available diet enriched with arginine, omega-3 fatty acids, and RNA, recently has been shown to extend rat cardiacallograft survival when combined with a donor-specific transfusion (DST) and cyclosporine A (CsA). Because mycophenolate mofetil (MMF) is now commonly used in the clinical setting, the current study was designed to examine the effect on rat cardiac allograft survival when MMF was added to this immunosuppressive regimen. Methods: Intra-abdominal ACI to Lewis heterotopic cardiac allografts were performed. Study groups included untreated controls and recipients receiving varying combinations of a DST (1 mL) on the day prior to engraftment, MMF45 mg/kg/day from the day of transplant through postoperative day six, andCsA 10 mg/kg on the day prior to operation and 2.5 mg/kg from the day of transplant through postoperative day 6. Animals were fed ad libitum with Impact diet or standard lab chow. Graft survival was determined by cessation of a palpable heartbeat. Results: Treatment with MMF led to a prolonged allograft survival over historical untreated controls. The combination of MMF with a donor-specific transfusion, Impact, or CsA was associated with an increase in graft survivalover MMF alone. The addition of Impact to the combination of MMF and CsA resulted in further improvement. The most pronounced graft survival advantage was seen when Impact was combined with a DST and both of the immunosuppressive agents. One quarter of the animals in this group had a palpable donorheart beat at greater than 150 days, indicating functional tolerance in those animals. Conclusions: The administration of Impact diet to treatment groups in thisstudy was associated with graft survival advantages when compared to most of the other study groups receiving a similar drug regimen and standard chow. These findings support the importance of nutritional influences on allograft survival, and highlight the potential of diet therapy when used with short courses of clinically relevant immunosuppressive drugs.
