Gastroesophageal reflux in patients with asthma and chronic bronchitis.

摘要: To determine the relationship between gastroesophageal (GE) reflux and pulmonary disease, we studied 21 asthmatics, 30 chronic bronchitics, 6 patients with GE no symptoms, 10 control subjects; was diagnosed by pH monitoring scintiscanning. Frequency of in asthmatics 57%; bronchitics it 56%. Pulmonary function tests did not show any differences or without reflux. The episodes were more numerous but shorter than bronchitics. Patients digestive symptoms alone different from respect to mechanism whereby triggers problems investigated using following 2 tests: scintiscan for aspiration, esophageal acid infusion (0.1N HCl). Six aspirations detected. Only reflux, showed significant variations maximal expiratory flow at 50% 25% VC after HCl infusion. Thus, our results that differ characteristics their
