Background:
Helicobacter pylori (H. pylori) has been suggested to be associated with recurrent aphthous stomatitis (RAS) as well as many other diseases.
Methods:
We conducted a prospective study on a total of 23 patients with RAS to investigate the relationship between H. pylori and RAS as well as the effect of eradication therapy on the recurrence. All patients underwent endoscopic examination and gastric biopsy. The biopsy materials were examined histopathologically whether they contained H. pylori or not. The density of H. pylori was also noted. The patients with H. pylori infection were followed up for up to 1 year after starting the eradication therapy.
Results:
Gastric mucosal H. pylori colonization was + in 39%, ++ in 39%, +++ in 9%, and - in 13% of the patients, respectively. There were statistically significant decreases in the recurrence rate and amelioration time of RAS by eradication therapy. There were no significant correlations among the intensity of H. pylori with the recurrence rate, number, diameter, and amelioration time of the lesions in 1-year follow-up.
Conclusions:
We concluded that eradication of H. pylori may have reducing effects on the recurrence and amelioration period of the RAS.

Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
