✦ Synopsis


Some patients with systemic light chain amyloidosis develop bleeding complications that can be caused by vascular infiltration with amyloid or by alterations of the coagulation or fibrinolytic systems. Factor X deficiency is the most common cause of bleeding manifestations, although deficiencies of other clotting factors, a disruption in the conversion of fibrinogen to fibrin, and circulating heparin-like anticoagulants have also been reported. Deficiency of factor X is a well-recognized cause of bleeding manifestations in patients with light chain amyloidosis. This acquired disorder appears to be secondary to adsorption of factor X to the amyloid fibrils. Previous studies have shown that infusion of plasma into patients with acquired factor X deficiency and amyloidosis induces a transitory improvement of the coagulation tests. However, there is a rapid return to pretransfusion levels. In this manuscript we report the clinical application of plasma exchange in the management of a patient with systemic light chain amyloidosis with acquired factor X deficiency. Am.

Combined hereditary deficiency of coagulation factors V and Vlll is a very rare bleeding disorder. The severity of bleeding is determined by the level of these factors, although in general, this is less striking than the severe deficiency of either factor alone.

## Abstract The plasma level of tumor necrosis factor (TNF) was determined in 20 normal individuals, 52 patients with disseminated intravascular coagulation (DIC), 22 pre‐DIC patients, and 39 non‐DIC patients. TNF was not detected in the normal subjects, and the level was very low in non‐DIC patien
