American Journal of Gastroenterology 89: 10(OCT 1994):1793-1796. Conclusions: We conclude that seroconversion, which usually occurs after 1 yr, indicates complete eradication of H. pylori. Furthermore, we suggest that the success of the eradication of H. pylori can be judged without endoscopic examination, 8 months after treatment by triple therapy, according to the fall of IgG titers or seroconversion. Re-elevating IgG titers may be a warning of the possibility of relapse or reinfection of H. pylori.

Results: The patients were found to suffer from otolaryngological disorders (26%), dental problems (23%), oral discomfort (18%), and gastrointestinal pathology (10%), or several of the above. In 31% of the patients, however, no clinical involvement was detected. The salivary flow rates in the patients were similar to those in healthy controls, whereas their oral Candida carrier rate was low (28%).
