Abstract
Haptoglobin (Hp) is a polymorphic plasma protein with multiple functions defined by three major phenotypes (Hp 1-1, Hp 2-1, and Hp 2-2). In this article, the effects of the donor Hp phenotype (determined by starch gel electrophoresis) on the outcome and the iron status after liver transplantation were investigated. A total of 450 liver transplant patients were enrolled in this study with a median follow-up of 37 months. Kaplan-Meier and Cox regression survival analyses showed a significantly worse graft survival for liver transplantation cases with an Hp 2-2 donor phenotype, which was associated with an increased mortality rate in this group. In male patients, the Hp 2-2 phenotype was associated with higher serum ferritin concentrations, which may be linked to the significantly increased likelihood of infectious complications in this phenotype. Liver transplant patients with Hp 1-1 and Hp 2-1 grafts had a better outcome probability than recipients of an Hp 2-2 graft, which may be explained by differences in iron metabolism induced by the Hp genotype of the graft.
