Hyperhomocysteinemia is a risk factor for arterial and venous thrombosis. However, towering homocysteine (Hcy) with vitamins not only failed to improve outcomes but also may lead to recurrent events. Our objectives were to evaluate Hcy and cysteine (Cys) levels in patients with thrombosis in different vascular sites, and their response to folate. One hundred and sixty four consecutive patients with thrombosis (42.1% arterial (AT), 36% venous (VT), 4.9% both venous and arterial thrombosis (AVT) and 17% unusual site (UST)) were included. Hcy and Cys. were highest in patients with AVT and LIST (p=0.0006). Ninety-three patients were treated, 70% were followed-up. Hcy levels normalized after therapy in all patients. Cys levels tended to vary after therapy according to the site of thrombosis. We observed a significant correlation between folate and Hcy (r: 0.48; p=0.005) among homozygous for MTHFR. A significant inverse relation was observed between Hcy and folate among homozygous and heterozygous (r: 0.462, p=0.007 and r: 0.267; p=0.04, respectively). No correlation was observed between folate and Cys. In conclusion, our observations suggest that Hcy and Cys might be implicated in thrombosis in different vascular sites, and respond differently to folate. (c) 2008 Elsevier Ltd. Alt rights reserved.
