title: Evaluation of glycogen loss in human liver transplants. Histochemical zonation of glycogen loss in cold ischemia and reperfusion.
abstract: To find a prognosis model of human liver transplant, we evaluate 62 surgical biopsies for the loss of glycogen and its variations in relation to cold ischemia, reperfusion, lobular zonation and donor's ages. We applied univariate, multivariate and discriminant analysis and logistic regression. There was a clear lobular zonation of glycogen during cold ischemia and at reperfusion. During cold ischemia, the mean loss was 48% in periportal zones and 74% in pericentrilobular zones. At reperfusion, it was in the range of 60% in periportal zones and 95% in pericentrilobular zones. It was observed in 64% of the grafts for an ischemia time less than 10 hr and in 82% of the grafts for an ischemia time of 10 hr or more. It was increased by 90% at reperfusion with pericentral predominance. Donors' age was an aggravating factor of glycogen loss beyond 28 years of age. In conclusion, in periportal zones, mean global glycogen depletion was about 54% during cold ischemia and reperfusion. It decreased by 90% at reperfusion with pericentral predominance. Logistic regression has allowed modelization of cold ischemia and reperfusion.
