Helicobacter pylori play an essential role in the pathogenesis of upper gastrointestinal disorders. The diagnostic role of the bacterium thus has been a subject of intense investigations. In this study we used an immune-chromatographic method and the polymerase chain reaction (PCR) to detect H. pylori in the saliva of patients with clinically diagnosed upper gastrointestinal disorders. Thirty such patients reporting to the Korle-Bu Teaching Hospital (Accra, Ghana) for upper gastrointestinal endoscopy consented for this study. Saliva samples were collected from each subject and analysed for H. pylori antibodies using a rapid immuno-chromatographic assay and H. pylori DNA by nested PCR using specific primers. Ten (33.3%) out of the 30 samples tested positive for the saliva antibody test with the most prevalent gastrointestinal disorders among the positive subjects being peptic ulcer (60%) followed by gastritis (30%) and esophagitis (10%). Following nested PCR analysis, a 346bp fragment of the vacA (m2) gene region of H. pylori was amplified in 9 (90%) out the 10 samples that were positive by the rapid immuno-chromatographic assay. Saliva samples could serve as a reliable non-invasive alternative to detect the presence of H. pylori infection in synergy with available diagnostic methods in Ghana.
