title: Comparison of histidine-tryptophan-ketoglutarate solution (HTK) and University of Wisconsin solution (UW) in adult liver transplantation.
abstract: Histidine-tryptophan-ketoglutarate solution (HTK) and University of Wisconsin solution (UW) have been shown to have similar outcomes in cadaveric kidney, pancreas, and liver transplantation. Our institution changed from UW to HTK as the primary preservation solution for liver, kidney and pancreas transplantation. This study compares the perioperative and first year outcomes of liver transplantation using UW or HTK. Primary use of HTK began on May 1, 2003. We reviewed the records of all adult liver transplant recipients from July 1, 2002 to December 31, 2004. Recipients were compared based on organ preservation solution (UW n = 204, HTK n = 174). Outcomes included 1-, 6- and 12-month graft and patient survival and 1-, 7-, 14-, and 30-day liver function and serum creatinine. During the entire study period, the two groups were managed similarly in operative technique, immunosuppressive regimens, and donor liver criteria. Over 30 months, 378 adult patients underwent liver transplantation. There were no significant differences between UW and HTK in 1-, 6-, or 12-month graft or patient survival. The HTK group had a higher day 1 median AST, ALT, and total bilirubin, but the two groups were similar thereafter. An anticipated difference in infused volume between UW and HTK was demonstrated. In conclusion, to our knowledge, this is the first reported large case series from North America comparing HTK and UW in liver transplantation with 2- to 12-month follow-up. There were no significant differences between HTK and UW in this population when comparing 1 month graft function and first-year graft and patient survival.
