[The association between gastroesophageal reflux and recurrent lower respiratory tract infections and bronchial asthma in children].

Introduction: It is well known that gastroesophageal reflux (GER) coincides with chronic diseases of the lower respiratory tract. However, the impact of effective management of gastroesophageal reflux on the course of coexisting pathologies of the lower respiratory tract has not been unequivocally evaluated. This study was undertaken to assess the impact of treatment of gastroesophageal reflux on the course of recurrent lower respiratory tract infections and bronchial asthma in children.
