Prandoni P, Tormene D, Perlati M, Brandolin B, Spiezia L. Department of Medical and Surgical Sciences, Thromboembolism Unit, University of Padua, 35128 - Padua, Italy. [email protected] BACKGROUND: Idraparinux is a synthetic pentasaccharide that binds to antithrombin with high affinity. In view of its long half-life, it is suitable for once-a-week administration. OBJECTIVE: To review the evidence favoring the use of idraparinux for the acute and long-term treatment of patients with venous thromboembolism (VTE) and for the prevention of thromboembolic events in patients with atrial fibrillation (AF). METHODS: All preclinical and clinical studies carried out with the use of idraparinux were sought through electronic searches of MEDLINE from January 1, 1999 up to December 31, 2007. RESULTS: The administration of idraparinux in subcutaneous fixed doses of 2.5 mg once weekly was found to be as effective and safe as conventional antithrombotic therapy in the initial treatment of patients with deep vein thrombosis, but less effective than standard therapy in the initial treatment of patients with primary pulmonary embolism. During a 6-month extension of thromboprophylaxis, idraparinux was effective in preventing recurrent VTE but was associated with an increased risk of bleeding versus placebo. Finally, in patients with AF the long-term treatment with idraparinux was as effective as vitamin K antagonists, but caused more bleeding. CONCLUSIONS: In its current formulation, idraparinux can be recommended only for the initial treatment of patients with deep vein thrombosis. The bioequipotency of a biotinylated version of idraparinux (idrabiotaparinux), whose effects can be reversed by a neutralizing agent (avidin), is under investigation in the treatment of VTE at present, as is the use of lower doses in patients with AF.

    Clin Appl Thromb Hemost. 2009 Oct;15(5):535-9. Epub 2008 Jun 29. The risk of cancer progression in women with gynecological malignancies and thrombophilic polymorphisms: a pilot case-control study. Tormene D, Beltramello P, Perlati M, Brandolin B, Barbar S, De Toffoli G, Simioni P. Department of Medical and Surgical Sciences, Second Chair of Internal Medicine, University of Padua Medical School, Padua, Italy. [email protected] Cancer produces a hypercoagulable state, which might lead to thrombosis, and on contrary, unprovoked venous thromboembolism might be the manifestation of an occult cancer. In this pilot case-control study, we assessed the risk of gynecological malignant diseases related to the presence of the factor V Leiden and prothrombin G20210A polymorphisms. Fifty-two women underwent an operation for gynecological malignancy and were enrolled in the study. Women who underwent an operation for gynecological nonmalignant disease in the same days of cases were considered as controls. The presence of factor V Leiden and prothrombin G20210A was assessed in case and control groups. In all, 7 out of 52 cases were carriers of the 2 polymorphisms compared with 20 out of 198 controls (odds ratio = 1.3; 95% confidence interval, 0.6-3.0). The results were also similar when the risk was considered separately for the site of cancer. As for advanced and metastatic malignancies, the odds ratios were 2.3 (95% confidence interval, 0.9-6.0) and 3.3 (95% confidence interval, 1.0-11), respectively, compared to noncancer patients. When these 2 groups were compared to nonadvanced cancer group, the odds ratios for carriers of polymorphisms were 2.7 (95%confidence interval, 0.7-11.0) and 3.9 (95%confidence interval, 0.8-18.6) for advanced cancer and metastatic malignancies, respectively. Women with factor V Leiden or prothrombin G20210A polymorphisms who developed gynecological malignancy might present with a higher stage of cancer at the time of surgery. Larger case-control studies in similar cohort of patients are needed to confirm these findings. PMID: 18591179 [PubMed - indexed for MEDLINE
