To investigate the presence of Helicobacter pylori (H. pylori) in bronchial biopsies of patients with bronchiectasis, by histochemical and immunochemical staining. 800-bed tertiary university hospital. Observational study. forty-six patients with bronchiectasis in a stable clinical condition and 8 control patients. Serum samples determination of IgG levels for H. pylori by ELISA. Immunostaining with an anti-H. pylori antibody (NCL-HPp, Novocastra) of bronchial mucosa obtained by fiberoptic bronchoscopy from both patients with bronchiectasis and controls. Twenty-one out of 46 patients with bronchiectasis (46%) had positive serology for H. pylori. We obtained 40 bronchial biopsies in patients with bronchiectasis and 8 bronchial biopsies in control patients.
