Improved viability of hepatic allografts from fasted donors is associated with decreased peripheral TNF activity.
Despite improvements in preservation solutions, hepatic allografts continue to be lost from primary nonfunction. Previous work by this group and others has established that donor fasting improves the viability of hepatic allografts. We have also established an association between viability of stored organs and serum TNF levels. The purpose of this study was to determine whether improved viability of hepatic allografts from fasted donors is associated with lower peripheral serum TNF levels. TNF was measured using a bioassay employing a WEHI cell line. Transplanted livers from fasted donors displayed gross deglycogenation had less bile flow postrevascularization and increased postoperative AST, but had significant improvement in viability and were associated with significantly less TNF recovered from the peripheral circulation. The association of improved viability and diminished serum TNF and previous work that links changes in postrevascularization TNF levels with changes in Kupffer cell activity suggest a possible cause for improved survival of recipients of fasted allografts.
