Six subjects reached a > or = 20% decrease in FEV1 (range 21-24%) after a fourfold increase in concentration. Five subjects had a decrease in FEV1 of greater than 40%, and this decrease occurred after a doubling concentration. Cough, flushing, and chest tightness were noted in 18% of the subjects. In 56% of the tested subjects, the shortest provocation scheme (phosphate solution followed by 4, 16 and 32 mg.ml-1 histamine) was applied, resulting in a time reduction of nearly 50% per test, and reducing the time needed to complete the study from 5 to 3 months. The shortened test was repeatable within one concentration difference.(ABSTRACT TRUNCATED AT 250 WORDS)
