- Abstract:
- Steatosis in donor livers is an accepted adverse prognostic factor after liver transplantation. While its semiquantitative assessment shows varying reproducibility, it is questioned as a standard method. Additionally, the influence of hepatic steatosis on ischemia/reperfusion injury (I/R injury) has not been evaluated in biopsies after reperfusion. We compared different staining and analyzing methods for the assessment of donor liver steatosis in order to predict I/R injury and clinical outcome after transplantation. To do this, 56 paired pre- and post-reperfusion liver biopsies were analyzed for macro- (MaS)/micro- (MiS) and total steatosis in cryo and permanent sections by special fat (Oil Red O or ORO) and standard stains. Computerized morphometrical analyses were compared to the semiquantitative assessment by a pathologist. I/R injury was determined histopathologically and by M30 immunohistochemistry. We found ORO to be more sensitive in detecting hepatic steatosis with higher reproducibility for MaS. Semiquantitative analyses were highly reproducible and not inferior to computerized morphometry. Categorized MaS as determined by ORO correlated with the extent of I/R injury, initial poor function, liver enzymes, and survival. Therefore fat stains like ORO are a reliable and easy method comprising significant advantages in the evaluation of hepatic steatosis and are thereby of prognostic value. Computerized analysis is a precise tool though not superior to semiquantitative analyses.
