BACKGROUND: The etiopathogenesis of chronic inflammation at the gastric cardia is still debated. It is suggested that carditis may be a finding of gastro-oesophageal reflux disease (GORD) or it may occur as a result of the gastritis caused by Helicobacter pylori (H. pylori) infection. AIM: To examine morphological features of carditis, as well as the associations of carditis with Helicobacter pylori gastritis and oesophagitis as a marker of gastro-oesophageal reflux disease. PATIENTS AND METHODS: Endoscopic biopsy specimens obtained systematically from oesophagus, cardia, corpus and antrum of 135 dyspeptic patients were retrospectively evaluated. In biopsies, we have searched for any correlations between clinical, endoscopic, and histological features. RESULTS: Carditis was detected in 123 (91.1%) of the cases. The mean age of the carditis group was 47.9 years and the male-to-female ratio was 1.08:1. The relation of carditis with age and sex was not significant (p = 0.19 and p = 0.24, respectively). All cases of the carditis group had concomitant chronic gastritis. In these cases, chronic inflammation, degree of neutrophil-mediated activity and H. pylori colonisation were significantly correlated in cardia, corpus and antrum (p < 0.001). Intestinal metaplasia was observed in 14 cases (11.3%) and, was associated with H. pylori colonisation (p < 0.001). Microscopic oesophagitis detected in 37.7% cases also showed correlation with reflux symptoms and endoscopic oesophagitis but not carditis. When all cases with carditis were evaluated for H. pylori infection and oesophagitis, which are presumed risk factors for carditis, H. pylori infection appeared to be an independent risk factor for carditis (p = 0.012), while oesophagitis did not. CONCLUSIONS: This study suggests that carditis is commonly found in patients presenting with dyspepsia and the histological features of carditis were similar to those seen in H. pylori gastritis in antrum and corpus. In addition, our data have also shown that carditis was significantly associated with H. pylori infection but not with symptoms or signs of GORD.
