RESUMO

An assessment of gastroesophageal reflux in children and adolescents with severe atopic asthma with and without recurrent pneumonia In order to evaluate the role of gastroesophageal reflux (GER) as a possible cause of recurrent pneumonia (RP) in children and adolescents with severe atopic asthma (AA), 44 patients were studied prospectively with prolonged (24hour) esophageal pH-monitoring. Their ages ranged from ? to 15 years. There were no significant differences detected between group 1 (AA without RP) and group 2 (AA with RP) when sex, age, maternal or paternal smoking, atopic status, and lung function tests were evaluated. The prevalence of GER was 31,6% (6/19) in group 1 and 48% (12/25) in group 2. The following parameters were evaluated: mean percentage of time pH<4, the number of GER episodes/hr, esophageal clearance and the longest reflux episode. Esophageal acid exposme (mean percentage of time with pH<4) (p= 0,00245) and the number of GER episodes/hr (p=0,0091) in supine position were significantly increased in group 2 as compared to group 1. Furtherrnore, group 2 shows higher values of !lUmber of GER episodes/hour (p=0,043). Thus, our results show that patients with AA and RP differ from AA without RP by the characteristics of their refluxo We therefore, suggest to perforrn prolonged esophageal monitoring as a standard procedure in asthmatic patients with RP
