United States' factor XI-deficiency patients need a safer treatment.

ABSTRACT

A replacement factor for Factor XI with is virally inactivated is not available in the U.S. Elsewhere an inactivated concentrate has been used. A review of the experience over 15 years suggests that this product is safe and effective and suggests its potential use in the U.S. The most serious complication of the factor was a slight increase in DIC and thrombotic events.
