Sixty-seven nasal and bronchial provocation tests were performed with Australian pine pollen extract (APE) on 61 subjects. A positive nasal response was elicited in 10 of 14 (71%) subjects with allergic rhinitis and positive APE skin tests and in none of 23 control subjects with negative APE skin tests. A positive bronchial challenge was elicited in 5 of 10 (50%) extrinsic asthmatics with positive APE skin tests and in none of 20 control subjects with negative APE skin tests. Australian pine pollen-specific IgE was demonstrated by conventional RAST (greater than or equal to + 1) in 6 of 14 (42%) subjects with a positive nasal challenge, and in 4 of 5 (80%) subjects with a positive bronchial challenge. The Australian pine pollen is an aeroallergen.
