Gastroesophageal reflux disease in bronchial asthma and the response to omeprazole.

The objective of this study was to determine the incidence of gastroesophageal reflux disease (GERD) in bronchial asthma and the role of omeprazole for asthmatics with symptoms of GERD. Seventy asthmatics were screened for GERD by questionnaire. Patients with a history suggestive of GERD were confirmed by Bernstein test and further investigated for airway responsiveness to instillation of HCl in the esophagus. Symptom score, drug score and spirometric values were recorded initially and after four weeks of treatment with omeprazole. It was found that 74.28% of asthmatics had a history of GERD. Forty patients tested positive by Bernstein test and also showed airway responsiveness to instillation of HCl in the esophagus. There was a significant improvement in symptom scores (p < 0.001), drug scores (p < 0.001) and spirometric values (p < 0.001) after adding omeprazole to their treatment regimen. It was concluded that bronchial asthma and GERD are associated in the majority of patients (57.14%) and such patients are likely to improve with omeprazole.
