  1. Epidemiology of Helicobacter pylori in chronic haemodialysis patients using the new RIBA H. pylori SIA.

    Article - En anglais


    There are few data concerning the epidemiology of H. pylori in patients on chronic haemodialysis (HD) treatment.

    These surveys concerned small populations and were made with ELISA technique.

    However, ELISA-based assays do not differentiate between strains of H. pylori that are associated with ulcers.

    Recent literature reports that formation of ulcers correlates strongly with the expression of cytotoxin-associated protein (CagA) and vacuolating cytotoxin (VacA) of H. pylori.


    A novel serological test (RIBA H. pylori strip immunoblot assay (SIA)) has been recently introduced, it uses the H. pylori lysate (Lys) along with two additional purified recombinant antigens derived from CagA and VacA of H. pylori.


    To study the epidemiology of H.

    Pylori using RIBA H. pylori SIA among chronic HD patients and blood donors as a control group.

    In addition, the activity of H. pylori was analysed by immunoblot technique in a group of patients with documented ulcers and normal renal function.


    The prevalence of antibody towards H. pylori among HD patients, blood donors, and patients with documented ulcers was 56% (127/228), 53% (84/158), and 100% (21/21) respectively ; the difference was significant (P=0.0001).

    The frequency of anti-H. pylori-positive individuals was significantly higher in patients with documented ulcers than HD patients and blood donors, 21/21 (100%) vs 211/386 (55%), P=0.0001. (...)
