To the Editor:
On page 1579 of the manuscript entitled “Specific inhalation challenge in the diagnosis of occupational asthma: consensus statement”, a consensus statement published in the June 2014 issue of the European Respiratory Journal, it is stated: “…the duration of exposure should preferably be increased from one day to the next with, for instance, a cumulative exposure limited to <30 min on the first challenge day,” after which reference numbers 11, 13 and 57 are cited [1].
I am the co-author of reference 11 and in this text we say, in table 2 (page 234), to limit exposure to 1 min on the first day, 5 min on the second day and 30 min on the third day [2].
So, our reference was wrongly quoted. Exposing subjects for 30 min on the first day can lead to severe reactions, which can explain the relatively high frequency of such reactions as referred to in the paper referenced as 57 [3].
