Summary
Fibrin crosslinking was assayed in 22 patients with acute leukemia showing secondary
coagulation abnormalities of variable severity. In 9 patients fibrin crosslinking
was found to be normal, whereas 10 patients presented impaired polymerization of α-chains
and 3 of both α- and γ-chains.
Only a rough correlation was found between transamidating activity of factor XIII
and the fibrin crosslinking pattern in these patients. Moreover, incomplete fibrin
crosslinkage occurred at levels of factor XIII far in excess of that required for
full polymerization of fibrin in “normal” plasma. This latter finding suggests that,
in addition to factor XIII deficiency, other causes are responsible for thehigh rate
of fibrin crosslinking impairment in acute leukemia.
