The paradoxical association between inherited factor VII deficiency and venous thrombosis.

Inherited factor VII (FVII) deficiency is considered to be a haemorrhagic disease. Nonetheless, some patients paradoxically present with venous thrombosis. We assessed whether there was a link between phenotype and genotype in seven patients with inherited FVII deficiency and thrombosis (eleven venous thrombotic events).

[Portal vein thrombosis associated with factor V Leiden mutation in a woman who underwent exchange transfusion at birth].

We report the case of a 18-year-old woman with portal vein thrombosis and chronic hepatitis C virus. Portal vein thrombosis was diagnosed by chance on ultrasound examination during initial hepatitis C virus-positive patient screening. The patient interview revealed a history including exchange transfusion at birth, followed by necrotising ulcerocolitis and septicemia.

Acquired inhibitor to factor VIII in a patient with Hodgkin's disease following treatment with interferon-alpha.

We describe a young woman who developed acquired haemophilia after 18 months of interferon (IFN-)-alpha therapy. This patient had been monitored since 1992 for Hodgkin's disease initially treated by chemotherapy. After two relapses, she received intensive chemotherapy followed by an autologous peripheral progenitor cell graft.

CD5 negative B-cell chronic lymphocytic leukemia: clinical and biological features of 42 cases.

Chronic lymphocytic leukemia cell (CLL) usually (95%) express B-phenotype and the CD5 antigen which is usually present on the surface of normal T cells. However, among B CLL, 7 to 20% do not express CD5. The significance of the lack of CD5 expression remains unclear.
