2088. Helicobacter pylori (protein CagA), IgA antibodies
Description
Helicobacter pylori is a bacterium that lives in the stomach lining. Helicobacter pylori infection provokes the development of gastritis and gastric ulcer and duodenal ulcer, can cause oncological diseases of the gastrointestinal tract.
There are two types of bacteria – one synthesizes the CagA protein, and the other does not. The presence of the CagA protein makes the bacteria more dangerous (increases the risk of developing severe gastritis and cancer).
Determination of specific IgA antibodies to the CagA protein allows to confirm the infection of the organism with Helicobacter pylori and to determine its subspecies.
The test is used to diagnose and assess the risk of developing gastritis, peptic ulcer, stomach and duodenal cancer, as well as to predict their severity.
When and who needs the test?
- examination of the patient with symptoms of gastritis and/or gastric ulcer;
- monitoring the effectiveness of therapy.
