RESUMO
AIM: To study the effect of eprosartan, an angiotensin II type 1 (AT1) receptor blocker, with sympatholytic activity on the hemostatic system in patients with chronic kidney disease (CKD) associated with hereditary thrombophilia. SUBJECTS AND METHODS: The 12-week open-label uncontrolled trial included 31 patients with Stages I-II CKD: 15 patients with chronic glomerulonephritis and 16 with diabetic nephropathy burdening types 1 and 2 diabetes mellitus (DM) in 10 and 6 cases, respectively. In all the patients, CKD was associated with one of the heterozygous forms of thrombophilia: the polymorphic methylenetetrahydrofolate reductase gene variant C677T was found in 18 patients; the polymorphic coagulation factor V gene variant G1691A was in 9; and the polymorphic coagulation factor II gene variant G20210A in 4. Along with the thorough examination accepted in nephrology and endocrinology clinics, investigations of vascular-thrombocytic and secondary hemostasis and the anticoagulant and fibrinolytic systems were made before and after treatment. RESULTS: Eprosartan therapy caused positive changes in the indicators of vascular-thrombocytic (diminished platelet aggregation, reduced surplus of von Willebrand factor and endothelin-1) and secondary (decreased coagulation factor VII activity, longer activated partial thromboplastin time) hemostasis and the anticoagulant (reduced antithrombin III deficiency) and fibrinolytic (elevated blood plasminogen concentrations) systems. CONCLUSION: The pleiotropic effects of eprosartan may be used to correct hypercoagulability syndrome in patients with CKD associated with hereditary thrombophilia.
