A 76-year-old man presented with dysphagia and odynophagia. Five years earlier, he had undergone a partial gastroesophageal resection for adenocarcinoma of the esophagus. Over the past few years he had also required several dilations for pyloric stenosis (secondary to vagotomy). He had a history of chronic bronchitis with frequent exacerbations treated by short courses of antibiotics. An upper gastrointestinal endoscopy was performed. The esophageal mucosa was covered by circumferential, white-gray, adherent plaques (Figure [1]). The antral mucosa had a nodular appearance and was covered by yellowish deposits (Figure [2]), and nodular folds covered by yellowish debris were seen in the pyloric region (Figure [3]). Histological examination revealed a picture of acute gastritis, with a rich inflammatory infiltrate dominated by neutrophils (Figure [4]). Cultures yielded isolates of Escherichia coli, Candida albicans, and Candida glabrata. The patient responded well to antifungal and antibiotic treatment.
Figure 1 At esophagogastroduodenoscopy, the esophageal mucosa was seen to be covered by circumferential, white-gray, adherent plaques.
Figure 2 The antral mucosa had a nodular appearance and was covered by yellowish deposits.
Figure 3 Nodular folds covered by yellowish debris were seen in the pyloric region.
Figure 4 Histological examination showed the typical changes of acute gastritis, with a rich inflammatory infiltrate dominated by neutrophils.
Fungal colonization in the stomach is common, and is associated with old age, malnutrition, diabetes, trauma, burns, surgery, total parenteral nutrition, intravascular or bladder catheterization, antisecretory therapy, immunosuppressive treatment, and the use of wide-spectrum antibiotics [1]
[2]. Bacterial gastritis is a rare entity, however, and most reports describe only one or two cases, with a review of the literature [3]. Several conditions have been reported as predisposing to bacterial gastritis, including immunosuppression, upper respiratory and buccopharyngeal infections [4], gastric ischemia, and endoscopic therapy (mucosectomy and polypectomy) [5]. Our patient probably developed esophageal candidosis secondary to long-term antibiotic use. Gastric stasis secondary to vagotomy and the respiratory tract infections may also have played a role in the development of the E. coli infection of the gastric mucosa.
We emphasize that endoscopic appearances such as these should raise the suspicion of infectious gastritis and that multiple biopsies with bacteriological examination should be performed to confirm the diagnosis.
