@entity1712 is a recently described condition in @entity1 with chronic cough, sputum @entity1712 , normal spirometry and no evidence of @entity6587 . The aim of the study was to assess the causes of chronic cough and to identify the prevalence of @entity1712 as a cause of chronic cough. Thirty-six @entity1 [mean age 45.4 +/- 14.3 years (range 16-69 years), M/F: 4/32] with an isolated chronic cough lasting for more than 4 weeks were recruited from the outpatient clinic. In all @entity1 , after a full history and physical examination, blood eosinophil count, @entity11153 ( @entity11153 ), serum total and specific IgE levels were measured. Spirometry, @entity2710 provocation test, skin prick tests, ear, nose and throat examination, induction of sputum and esophageal pH testing were performed. The mean duration of cough was 31.3 +/- 52.3 months. Sputum @entity1712 greater than 3% was present in 12 (33.3%) @entity1 and they were diagnosed as @entity1712 . Their induced sputum had a mean eosinophil count of 8.3% and a mean @entity11153 level of 98.5 mg x l(-1), which were higher than the others (P=0.003, both). The diagnosis of the remaining @entity1 were postnasal @entity751 in eight, @entity354 in eight, post-infectious cough in two and cough-variant @entity565 in one @entity1 . In conclusion, @entity1712 is an important cause of chronic cough and should be considered in the assessment of @entity1 before regarding them as having idiopathic chronic cough.

XXXX as a cause of chronic cough.
