Abstract
Abnormalities of haemorheology were found in animal and human recipients of kidney and/or pancreas allografts during rejection episodes. Thirteen diabetic canines received solitary pancreatic transplantation and another 13 diabetic and uremic canines underwent combined pancreas and kidney transplantation. Determination of haemorheological parameters was performed before and after operation respectively. During rejection episodes of kidney or pancreas allografts, the values of plasma viscosity, blood reductive viscosity and fibrinogen were significantly higher than those without rejection. On the basis of animal experiments, the determination of haemorheological parameters had been performed on 33 patients (30 receiving renal transplant, 2 pancreatic transplant alone and the remaining 1 combined renal and pancreatic transplant). Consecutive monitoring on these patients showed that a rise in the values of plasma viscosity, blood reductive viscosity and fibrinogen could be demonstrated during rejection episodes. The changes appeared one to three days prior to clinical manifestations and were in accordance with the termination of rejection. Our studies suggest that variation of haemorheological parameters are associated with rejection and the abnormal haemorheology may be an essential factor contributing to graft dysfunction. Moreover, the use of these assays will be beneficial to early diagnosis and better management of rejection in the future.
