20.500.12556/RUL-135957 The predictive value of the aCL and anti-β2GPI at the time of acute deep vein thrombosis—a two-year prospective study Antiphospholipid syndrome (APS) is an important cause of deep vein thrombosis (DVT). According to current APS classification criteria, APS cannot be confirmed until 24 weeks after DVT. This time frame results in frequent discontinuation of anticoagulant treatment before APS is diagnosed. Therefore, the aim of our study was to evaluate the potential predictive value of anticardiolipin (aCL) and anti-β2glycoprotein I (anti-β2GPI) before discontinuation of anticoagulation therapy. Patients with newly diagnosed DVT were included into a 24-month prospective study. All patients received anticoagulant therapy. aCL and anti-β2GPI were determined at inclusion and every four weeks for the first 24 weeks and then one and two years after inclusion. APS was confirmed in 24/221 (10.9%) patients. At the time of acute DVT 20/24 (83.3%), APS patients had positive aCL and/or anti-β2GPI. Two patients had low aCL levels and two were negative at the time of acute DVT but later met APS criteria due to lupus anticoagulant (LA). Our data indicate that negative aCL and/or anti-β2GPI at the time of acute DVT make further aPL testing unnecessary; however, LA should be determined after discontinuation of anticoagulant therapy. Positive aCL and/or anti-β2GPI at the time of acute DVT have a strong positive predictive value for APS and may support therapeutic decisions. thrombosis antiphospholipid syndrome antiphospholipid antibodies prediction tromboza antifosfolipidni sindrom antifosfolipidna protitelesa true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-05 08:15:03 2022-04-05 08:15:08 2022-09-15 04:12:57 0000-00-00 00:00:00 2021 0 0 10 str. iss. 8, art. 901 Vol. 9 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.1 2227-9059 10.3390/biomedicines9080901 72525315 RAZ_Perdan-Pirkmajer_Katja_2021.pdf RAZ_Perdan-Pirkmajer_Katja_2021.pdf 1 E3EDB728B9B24573B04D276CAA6A9825 584c7594a112c90abe2f511c25608465dd3b16a4016255173e69bdf0017a83fc 8fa6863c-b4a8-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155293 https://www.mdpi.com/2227-9059/9/8/901 1 b6d93351-b4a7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155292 Medicinska fakulteta Fakulteta za farmacijo 0 0 0
