[Proceedings: Hypercoagulability and compensated intravascular coagulation in chronic kidney insufficiency and after kidney transplantation].

Seven blood coagulation tests which may indicate a state of hypercoagulability or of chronic intravascular coagulation were assayed in 106 blood samples from 50 patients with chronic renal insufficiency or after renal transplantation. The following abnormal results were obtained: increased titer of fibrin(ogen) degradation products in 60%, abnormal fibrinogen immunoelectrophoresis in 49%, shortened partial thromboplastin time and whole blood clotting time in 45 and 37% respectively, prolonged thrombin time in 34%, increased cryofibrinogen level in 21% and positive protamine sulfate gelation test in 11%. The greatest number of abnormalities was found during the first week after transplantation and during transplant rejection, and the smallest in patients with stable transplant who were anticoagulated with warfarin. Partial thromboplastin times of less than 19 sec were associated in 3/4 patients with thrombosis of the renal artery or vein or with rejection. Rejections could be identified with high probability (p less than 0.001).
