| Clinical Significance: |
Helicobacter pylori is a spiral bacterium that can be cultured from human gastric mucosa. Various studies have indicated that the presence of H. pylori is associated with chronic (type B) gastritis, and gastric and duodenal ulcers. The presence of H.pylori specific IgG antibodies in human serum have been shown to be an accurate indicator of H.pylori colonization. A negative result indicates that the patient does not have detectable levels of antibody to H. pylori. If a sample is drawn too early in H. pylori colonization, IgG antibodies may not be present. The clinical diagnosis has to be interpreted with the clinical signs and symptoms of the patient. A positive result indicates that the patient has antibody to H. pylori. It does not indicate that any existing symptoms are due to H. pylori infection or colonization. It also does not differentiate between active or past infection. The clinical diagnosis has to be interpreted with the clinical signs and symptoms of the patient. Because the presence of the H. pylori organism is so common and because simple colonization is asymptomatic (vs. symptomatic infection), many individuals apparently free of gastrointestinal symptoms are antibody-positive. The height of antibody response is not correlated with the presence or severity of symptoms. |
