Fifteen @entity1 who presented with chronic cough as an isolated manifestation of @entity1576 were evaluated for the presence of exercise-induced @entity1224 . Pulmonary function tests using air and a helium/ @entity26 gas mixture were performed before exercise. Eight subjects were also evaluated by spirometry and maximum expiratory flow volume curves before and after @entity3044 inhalation on a separate day. Ten subjects had normal pulmonary function tests at rest and five had isolated @entity854 . No significant changes in pulmonary function tests were recorded after inhalation of @entity3044 in the eight subjects studied. Following exercise, all 15 subjects demonstrated changes in pulmonary function tests which were similar to those seen in @entity1 with mild exercise-induced @entity5143 . After institution of @entity2544 , exercise-induced decreases in flow rates low in the vital capacity were blocked in all subjects; however, several subjects had persistent mild decreases in peak flow. Within six months of discontinuing the @entity2544 , cough recurred in 11 of the 15 subjects. Nine subjects were restudied after return of their cough. Exercise again resulted in @entity6314 . Reinstitution of @entity2544 eliminated the cough in these nine subjects. This study demonstrates that chronic cough in some @entity1 may be a manifestation of @entity1224 . Both the cough and the reactivity can be blocked with @entity2544 .
