Gastroesophageal reflux symptoms and microscopic esophagitis in a cohort of consecutive patients affected by atrophic body gastritis: a pilot study

In patients affected by atrophic body gastritis (ABG) gastro-oesophageal reflux (GER) related symptoms have been reported, despite the presence of hypochlorhydria.Objectives of this single-centre study was to assess in ABG the occurrence of GER-related symptoms and their relationship with histopathologic oesophageal findings.Fifty-four consecutive patients (20.4%male, 57.6 ± 14 years) undergoing to follow-up for ABG, underwent assessment of GER-related symptoms and gastroscopy with multiple gastric and oesophageal biopsies to investigate the presence of microscopic esophagitis (ME).At least one typical GER symptoms were reported in 24.1% with 9.2% of patients complaining of heartburn and 18.5% regurgitation. One or more atypical GERD symptoms were reported in 44.4% of patients. Two symptomatic ABG patients presented oesophageal lesions at endoscopy (one with erosive esophagitis (LA-C) and one with Barrett's oesophagus (C2M2)), 49% reported a mild ME and 24.5% a severe ME. No significant differences regarding GERD prevalence were found among patients with or without ME, but cough was the only symptom significantly more frequent in patients with ME (38.95% vs. 7.7%, p = .042).These data showed that GERD is present in a quarter of ABG patients, suggesting that hypochlorhydria not exclude per se arising of oesophageal symptoms. In ABG we found that ME is a frequent finding but its clinical relevance remains to be investigated with further studies.
