[A case of chronic persistent cough (CPC) caused by gastroesophageal reflux (GER) (including a study of CPC caused by suspected GER)].

A patient, an 80-year-old female, had complained of a cough for 20 weeks, and was not cured by cough medicine. Gastroesophageal reflux was considered as the cause of the cough because of her symptoms and gastrointestinal fiberscopy (GIF) and barium meal studies. She made favorable progress on a histamine H2 blocker and cysapurid for 4 weeks. Therefore we diagnosed her cough as caused by gastroesophageal reflux. We also studied the incidence of chronic persistent cough in patients suspected of gastroesophageal reflux because of symptoms and GIF results. Among 676 cases examined by GIF at Niigata-kenritsu Myoko Hospital, we detected 7 cases who complained of heartburn and in whom we observed hiatal hernia and reflux esophagitis by GIF. Only one of them, the present case, complained of a cough. CPC caused by gastroesophageal reflux is not seen frequently, but the possibility of GER as the cause of CPC should be considered.
