Background: The prevalence of Gastro-esophageal reflux(GER) in patients with asthma is estimated to be 50~60% and treatment of GER has been shown to improve asthma symptoms in Western. But GER has been known to be less common in Eastern and GER prevalence rates in asthmatics are not available in Korea. Method: We compared the prevalence rate of GER in 42 patients with asthma to that in 20 healthy normal controls and examined the efficacy of new prokinetic drug, cisapride (40 mg/day, 8 weeks) in patients with GER and asthma. For acid GER to be considered pathological, 24 hour esophageal pH monitoring should reveal values exceeding upper limit of 95 percentile for at least one of 6 parameter of DeMesseter's table. Result: The results showed GER was more common in patients with asthma(11/42, 26.2%) than normal controls(3/20, 15%) and asthmatics group showed a significant longer supine time pH<4(%) and total time pH <4(%), and more reflux episodes as compared with normal control group. After 4 asthmatics with GER were treated with cisapride, their asthma symptom scores, FEV1 and composite scores of pH monitoring were improved. Conclusion: GER is more common in asthmatics than in normal controls in Korea and prepulsid reduces asthma symptoms in patients with GER and asthma.
