Open Access Abstract Introduction Heparin-induced thrombocytopenia is an immune-mediated adverse drug reaction that is associated with a procoagulant state and both arterial and venous thrombosis. After observing two cases of repeated hemofiltration-filter clotting associated with high anti-PF4 heparin antibody concentrations we systematically measured the anti-PF4 heparin antibody concentration in all cases of unexpected and repeated hemofiltration-filter clotting during continuous veno-venous hemofiltration CVVH . The aim of this study was to identify factors associated with positive anti-PF4 heparin antibody in the case of repeated hemofiltration-filter clotting. Methods We reviewed the charts of all patients who had an anti-PF4 heparin antibody assay performed for repeated hemofiltration-filter clotting between November 2004 and May 2006 in our surgical intensive care unit. We used an .
