Researchers identify new risk factor for DVT
Hospitalist Leadership Connection, September 11, 2007
Britain's Journal of Thrombosis and Haemostasis recently published the results of a retrospective study finding that the presence of anti-EPCR autoantibodies is a moderate risk factor for deep-venous thrombosis (DVT) in the general population. Anti-EPCR autoantibodies have been associated with fetal death and myocardial infarction in young women, according to the study's abstract.
The study measured plasma anti-EPCR autoantibody levels within the larger Leiden Thrombophilia Study (LETS), a population-based case-control study consisting of 474 patients with a first DVT and 474 control subjects.
The estimated risk of DVT was increased approximately twofold in the presence of elevated IgA, IgG, or IgM anti-EPCR autoantibodies (i.e., levels above the 90th percentile as measured in the control subjects).
