Abstract
Data on the effects of combined long-standing spinal cord injury (SCI) and end-stage renal disease (ESRD) on blood coagulation system are limited. We studied the extrinsic and common pathways of blood coagulation system in 9 men with SCI-ESRD treated with maintenance hemodialysis. Plasma procoagulant activities of factors (F)VII, X and II were measured in a clotting assay using appropriate deficient plasmas as substrate. In addition, the antigen concentration of FII was measured using monospecific antibodies against human FII raised in goat in a gradient plate immunodiffusion system. Also measured were plasma fibrinogen concentration and platelet count. The results were compared with those obtained in a group of 10 ambulatory ESRD patients and 8 normal control volunteers. Plasma coagulant activity of FVII was markedly elevated and plasma fibrinogen concentration was moderately increased in SCI-ESRD patients: In contrast, plasma FII was mildly depressed while platelet count was within normal limits in SCI-ESRD patients. The data indicate that the combination of SCI and ESRD can lead to the alteration of the extrinsic and common coagulation pathways. Further studies are needed to elucidate the precise mechanism and the clinical significance of the observed abnormalities.
