Abstract

Whether a distinct kapok allergen exists or whether the fiber's allergenicity is due to contamination by other allergens has never been resolved. Several years ago, we evaluated a patient who appeared to develop occupational asthma to kapok. We performed an environmental assessment, cross-shift spirometric testing of the patient's co-workers, and the first reported bronchoprovocation challenge with kapok. The disappearance of the patient's asthma following cessation of kapok exposure, with now 7 years of follow-up, our inability to incriminate any other agent, and the patient's positive specific bronchoprovocation challenge strengthen the evidence, but do not prove definitively, that kapok fiber itself is allergenic
