  1. Prevalence of hepatitis C virus infection in patients with antiphospholipid syndrome.

    Article - En anglais

    Background/Aims 

    The aim of this study was to determine the prevalence and clinical significance of hepatitis C virus (HCV) infection in patients with the antiphospholipid syndrome (APS).

    Methods 

    A series of 88 consecutive patients (78 female and 10 male), with a mean age of 39 years (range 15-79), was prospectively studied.

    All patients had been diagnosed with APS : 54 (61%) primary APS and 34 (39%) APS associated with systemic lupus erythematosus.

    A group of 200 apparently healthly blood donors was included in the study.

    Anti-HCV antibodies were investigated in the serum of all patients using a third-generation ELISA and confirmed by recombinant immunoblot assay.

    RNA-HCV was investigated in anti-HCV positive samples by polymerase chain reaction.

    Anticardiolipin, anti-bêta2-glycoprotein and antiprothrombin antibodies were evaluated by ELISA.

    Lupus anticoagulant was studied by coagulometric assays..

    Results 

    Only 2 (2.2%) patients showed positivity for anti-HCV antibodies, but none of them had clinical or biochemical signs of liver disease.

    Furthermore, RNA-HCV was not detected in serum of any of these patients.

    Lupus anticoagulant was positive in 57% of patients.

    Anticardiolipin antibodies were positive in 60% of patients, anti-bêta2-glycoprotein I antibodies in 43% of patients, and antiprothrombin antibodies in 56% of patients.

    The prevalence of anti-HCV in blood donors was 1%. (...)
