“…There was a significant association between the presence of H. pylori in the mouth and the stomach of infected children. The presence of the microorganism in the oral samples can be due to episodes of intermittent reflux [35] and supports the possibility that oral‐oral transmission may be a significant way of spreading H. pylori in children. Moreover it could be speculated that the recovery of bacterial DNA in the mouth of three noninfected subjects could represent an initial stage of transmission, not necessarily leading to gastric infection.…”

Based on the positivity of culture or urease rapid test and histology, infection was detected in 47 patients. The statistical analysis showed that, for the detection of the infection, stool antigen assay is more effective in sensitivity and negative predictive value (91.5% and 96.5%), whereas specificity and positive predictive values appear slightly better in serology (89.6% and 76.0%). Correlations between serum IgG both with patients' age (r = 0.21, p < .05) and H. pylori stool antigen (r = 0.47, p < .01) were found. The search for bacterial DNA on oral samples proved to be very specific (99.1% on saliva and 98.2% on plaque), but insensitive (22.2% and 25.7%). CONCLUSIONS. In children H. pylori stool antigen represents a sensitive test, suitable for detecting H. pylori infection. Serum IgG proved to be more specific; the PCR on the oral cavity resulted as being a very specific, but insensitive test.

“…Following H pylori infection, there is an initial immunoglobulin (Ig) M response followed by IgG conversion that accompanies the fall in the IgM titres (46). The 'common mucosal system' provides the conceptual framework for understanding the observation that antibody and saliva reflect immune events within the gastric mucosa.…”

Since its rediscovery 10 years ago,Helicobacter pylorihas reshaped our thinking about the course of peptic ulcer disease. Our approach to the patient with a duodenal ulcer has become one of attempting eradication therapy at the time of first diagnosis, in the hope of curing the ulcer disease. Gastric and duodenal ulceration are only two of the manifestations of this chronic antral infection; other complications ofH pyloriinclude gastritis, gastric cancer and possible maltomas. Therapy ofH pyloriinfection is complicated and involves dual therapy with an antibiotic plus a protein pump inhibitor, such as omeprazole 20 mg bid plus amoxicillin 1 g bid for two weeks, triple or quadruple therapy with bismuth, two antibiotics and an H2-receptor antagonist. Vaccination againstH pyloriis on the far horizon.
