Abstract:
OBJECTIVE One of the aims of this study is to know the morbidity of LPR in children with chronic cough. And also to explore the relationship among the morbidity of LPR,the pH value in the laryngopharynx, the frequency of ref lux events,the duration of ref lux with age, sex, position, allergy and so on. METHODS A retrospective analysis was conducted on 185 children with pH monitoring in Shanghai Children's Hospital from February 1, 2015 to August 31, 2018. The pH monitoring was taken in those patients for the reasons of chronic cough, and can't be remitted by regular treatment. The sex, diagnosis, allergy and the results of 24h pH monitoring were recorded. RESULTS A total of 185 cases were reviewed. 60％(111/185) were boys and 40％(74/185) were girls. LPR was present in 36.8％ of all the children(68/185). Compared with older patients, children younger than 12m had significant higher morbidity of LPR. Higher morbidity of LPR was also found in patients with food allergy. CONCLUSION LPR has high morbidity in children. In our study, 36.8％ of the chronic cough children combined with LPR. Children younger than 12m had higher morbidity of LPR. There may be a correlation between LPR and food allergy in children.
