Objectives: To investigate the association between clinical and macroscopic findings of GER and severity of refractory asthma (statistical study). Methods: A prospective study in a university-based practice of 75 children who were diagnosed with refractory asthma because they exhibited no satisfactory response for at least three months of treatment. Medical history, physical examination, spirometrical measurements and prick skin test were conducted on all patients. Endoscopic and macroscopic evaluations for esophagitis were performed on all patients regardless of the presence of GER symptoms. Results: Endoscopy was done for 75 children with refractory asthma. GER was symptomatic in 65% of all patients with no statistical significance (p>0.05) and the most frequent symptom was abdominal pain (67%). The frequency of these symptoms was 50% in mild asthma, 58% in moderate asthma and 72% in severe asthma with no statistical significance (p>0.05). The frequency of macroscopic esophagitis was 71%, distributed in three asthmatic groups as in order of 75% in mild asthma, 58.3% in moderate asthma and 76.6% in severe asthma (p>0.05). Regarding the relationship between GER and nocturnal attacks or spasmodic cough, the frequency of the latest was 66.7%. The differences have no statistical significance regarding GER symptoms (p>0.05), but they are statistically significant regarding the reflux esophagitis (p<0.05). Also endoscopic reflux was as frequent as76.3% in non allergic patients, and this result is statistically significant (p<0.05). Conclusion: In spite of the fact that there was no relationship between the severity of asthma and the symptoms of GER, or its endoscopic findings, the frequency of GER in asthmatic children was higher than its frequency in other children.
