Co-infection by duodenal giardiasis and helicobacter pylori. visualization of trophozoites in duodenal biopsy. Clinical impact of both entities on the same patient

Abstract Text A 63-year-old woman was referred for digestive consultations from the Otorhinolaryngology service to rule out gastroesophageal reflux due to chronic laryngitis. He sometimes reports symptoms of occasional heartburn and dyspepsia, which partially responds to taking proton pump inhibitors. Esophagogastroduodenal transit was performed, with no hiatus hernia or gastroesophageal reflux evident during the examination.

The study was completed with gastroscopy, showing data suggestive of chronic gastritis. Macroscopically, the duodenal mucosa appears normal. Gastric and duodenal biopsies are taken. In the pathological study, the presence of colonization by Helicobacter pylori and intestinal giardiasis trophozoites was observed, without duodenal villous atrophy. [1] [2] [3]
