Anti-Helicobacter Pylori Antibodies - Blood Analysis

Generality

Infection of the gastric mucosa by Helicobacter pylori causes a systemic (IgM, IgG) and local (IgA) immune response.

The antibody response to infection is greater the higher the bacterial load; consequently, it is possible to measure specific antibodies in the patient's blood to identify any colonization by Helicobacter pylori.

If from a biohumoral point of view, H. pylori infection is accompanied by the appearance of specific antibody titers in the serum, from a clinical point of view it is strongly associated with chronic, superficial or diffuse gastritis, dyspepsia, duodenal ulcer and gastric ulcer. recent epidemiological studies have shown that Helicobacter pylori gastritis is a risk factor for gastric cancer.
