An annoying persistent cough

Abstract

Chronic cough is a stressful condition and can lead to extensive investigations. We report a case of a 48-year-old woman who had suffered from persistent chronic cough for more than 3 months. She had been treated with cough suppressant. However, her cough was not alleviated by these treatments, and the patient was referred to our hospital. She did not exhibit typical gastroesophageal reflux disease (GERD) symptoms heartburn and regurgitation. Esophagoscopy did not disclose reflux esophagitis. The patient was treated with a proton-pump inhibitor, which markedly alleviated her cough. Chronic cough due to GERD was diagnosed. Although the diagnosis of chronic cough due to GERD is not easy when traditionally symptoms are not present, our case report underscores the importance of this association to the differential diagnosis of chronic cough. In these cases a relatively simple test as high dose proton pump-inhibitors trial may be useful to confirm GERD related cough.
