Properties
Background The gram-negative, spiral-shaped bacterium Helicobacter pylori was described by Warren and Marschall in 1983. The connection between chronic Type B gastritis and Helicobacter pylori has been well studied. In fact, there is a causal relation between Helicobacter pylori and almost all duodenal and stomach ulcers. Moreover, Helicobacter pylori is associated with an increased risk of gastric adenocarcinomas. Apart from strains of different virulence, host factors may also be responsible for this phenomenon.An infection with Helicobacter pylori induces a specific immune response. As a rule, antibodies of the classes IgG and IgA can be detected. Only small amounts of IgM antibodies are identified. Indeed, there is a decrease in the antibody concentration after successful eradication through combined antibiotic therapy.The eradication of Helicobacter pylori cures not only gastritis or peptic ulcer, but also low-malignant gastric MALT lymphomas. Although peptic ulcers are also cured without eradication of Helicobacter pylori, there is a recurrence within one year in up to half of all the cases in the absence of permanent acid suppression treatment. The rate of recurrence is less than 5 % per year after successful microbial eradication.

Description Test principle and procedure:

Indirect sandwich test. Recombinant antigens are bound to the solid phase.

1. 1st Incubation. Add patient samples diluted 1:101 (sample: 10 µl of serum or plasma), incubate for 1 h at 37 °C.
2. Wash 4 times
3. 2nd Incubation
4. Add peroxidase conjugated anti-human IgG or IgM antibodies (conjugate), incubate for 30 min at 37 °C.
5. Wash 4 times
6. Color reaction
7. Add ready-to-use TMB solution and incubate for 30 min at room temperature. Stop the substrate reaction with H3PO4 and measure the extinction at 450 nm.
