The role of serology in the diagnosis of Campylobacter pylori infection

Abstract

Circulating antibodies to Campylobacter pylori in patients with campylobacter-associated gastritis are sufficiently specific to allow serodiagnosis of this condition. This is possible by various techniques, the most convenient being enzyme-linked immunosorbent assay. Applications of serodiagnosis are in two areas--in clinical practice, where proper evaluation is still required, and in epidemiology. Here serodiagnosis shows the prevalence of C. pylori in the general population and in specific population groups. A study of C. pylori and dyspeptic symptoms in a group of healthy blood donors showed a significant association between C. pylori and history of peptic ulceration. However in most donors the gastritis was clinically silent.
