Abstract:
Two patients underwent liver transplantation of blood type incompatibility were collected from Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA. Case 1: A male who had primary hepatic carcinoma underwent classic orthotopic liver transplantation; the blood of donor was type A, and the blood of recipient was type O. Case 2: A female having history of type B hepatitis underwent classic orthotopic liver transplantation due to pregnancy combining with severe liver disease and coagulation disorder; the blood of donor was type B, and the blood of recipient was type O. Immunohistochemistry staining was used to observe pathological changes and deposition of various immunoglobulin and complement in two cases following liver transplantation of blood type incompatibility under optic microscope and to investigate diagnostic standard of humoral rejection. The results showed that linear or granular depositions of IgG, IgM, IgA, C4c, C4d, and Clq were found in endothelial cells of hepatic sinusoid, suggesting that IgG and other immunoglobulin exhibited a strongly positively diffused deposition on the endothelial cells of hepatic sinusoid, while expression of C4d and other complements was also found. All those mentioned above could be considered as evidences to prove onset of humoral rejection in transplanted liver tissue.
