Summary
Fibrinolytic factors were measured before and after DDAVP- infusion in 18 patients
on chronic, regular haemodialysis, 11 of whom underwent bilateral nephrectomy, and
in 7 patients in whom non-functioning kidneys were still present. Baseline fibrinolytic
activity was normal or high in all but two cases. Before haemodialysis, the response
to DDAVP-infusion was greatly reduced in the majority of patients as compared with
healthy controls, irrespective of the baseline level. This was in accordance with
mean t-PA-antigen levels which increased only slightly after DDAVP. When DDAVP was
given after haemodialysis, previous non-responders showed a normal increase in fibrinolytic
activity. The level of free t-PA-inhibitors was normal in most cases as were levels
of α2-antiplasmin. and α2-macroglobulin.
