Dysfibrinogenaemia associated with a defect in the aggregation of the fibrin monomers (Almeria I fibrinogen). A preliminary study.

A patient with functionally defective fibrinogen has been studied. Fibrinogen Almeria I was found to have a prolonged of latency time (LT) and a decrease in rate of gelation (RG) when plasma or isolated fibrinogen were activated by thrombin or reptilase. This fibrinogen also has the unusual formation of cross-linked fibrin; the existence of unpolymerized alpha chains was confirmed.
