The authors prospectively studied the risk for immune-mediated heparin-induced thrombocytopenia (HIT) in neurologic patients during administration of low-molecular-weight heparin (LMWH) vs unfractionated heparin (UFH). None of 111 neurologic patients receiving LMWH developed HIT, whereas HIT occurred in 2.5% of 200 patients treated with UFH (p = 0.17). The rate of heparin-induced antibodies in patients treated with LMWH was lower than in patients treated with UFH (1.8 vs 20.5%; p < 0.001). |
