We performed a retrospective cross sectional study of the prevalence of antiphospholipid antibodies (APA) in 68 ET patients. Compared to 200 elderly controls (> 50 years) there was a significant increase in anticardiolipin IgM (p < 0.0001) and anti β2 glycoprotein I (anti-β2GPI) IgM (p < 0.0001) antibodies in ET. Thrombosis occurred in 10/20 with APA and 12/48 without, p = 0.04, relative risk 2.0 (95% confidence intervals 1.03-3.86); these patients did not differ in terms of other clinical features. The prevalence of thrombosis in patients with dual APA (6/7) was significant when compared to those with single APA (p = 0.02) and the remaining patients (p < 0.0002). Also anti-β2GPI IgM antibodies either alone, or in combination with another APA, were associated with thrombosis (p = 0.02). These results suggest that the prevalence of APA in ET and their influence upon thrombotic risk merit investigation in a larger study. date: 2002-05 date_type: published official_url: http://www.schattauer.de/index.php?id=832&L=1&no_cache=1&artikel=11837 vfaculties: VGHCSCI rae2008: 4 oa_status: green language: eng primo: open primo_central: open_green lyricists_name: Mackie, I lyricists_name: Machin, S lyricists_id: IJMAC71 lyricists_id: SJMAC45 full_text_status: public publication: Thrombosis and haemostasis volume: 87 number: 5 pagerange: 802-807 refereed: TRUE issn: 0340-6245 citation: Harrison, C.N.; Donohoe, S.; Carr, P.; Dave, M.; Mackie, I.; Machin, S.J.; (2002) Patients with Essential thrombocythaemia have an increased prevalence of antiphospholipid antibodies which may be associated with thrombosis.
