Thrombophilic polymorphisms - factor V Leiden G1691A, prothrombin G20210A and MTHFR C677T - in Tunisian patients with cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) has been associated with thrombophilic defects. We performed a study to evaluate the role of three single nucleotide polymorphisms (SNP), factor V Leiden G1691A (FVL), prothrombin gene mutation G20210A (FII-G20210A) and methylenotetrahydrofolate reductase variant C677T (MTHFR-C677T), as risk factors for CVT in Tunisian patients. A single center case-control study (26 patients with CVT and 197 controls) was performed.

Hyperhomocysteinemia, C677T MTHFR polymorphism and ischemic stroke in Tunisian patients.

Background: Hyperhomocysteinaemia has been identified as a strong risk factor for ischemic stroke (IS). A point mutation in methylene tetrahydrofolate reductase (MTHFR C677T) has been associated with increased plasma homocysteine (Hcy) levels.

Aim: This preliminary study aimed to investigate whether hyperhomocysteinaemia and/or MTHFR C677T mutation are associated with ischemic stroke.

[Cerebral venous thrombosis: Prospective etiological study of 26 Tunisian patients].

Purpose: The aim of the present study is to provide a clinical and etiological analysis of cerebral venous thrombosis (CVT) in the Tunisian population.

Methods: This is a prospective monocentric study including 26 patients referred to the Neurology Department of the Military Hospital of Tunis between January 2005 and January 2008. The diagnosis of CVT was confirmed in all patients by magnetic resonance imaging (MRI) and angiography.

[Antiphospholipid antibodies in 146 women with repeated pregnancy losses].

Antiphospholipid antibodies are associated with arterial and venous thrombosis and recurrent abortions. However, the prevalence of these antibodies in repeated miscarriages varies in different reports. To obtain quantitative data with restricted criteria and discuss the origin of the variability on the literature, we investigated the presence of antiphospholipid antibodies in 146 women who had 2 or more consecutive pregnancy losses and in 99 women whose pregnancies were successful.
