In the article by Heratizadeh et al.¹, there are errors in the Results and Discussion sections. In the results section, it was stated that: “With regard to allergies, allergic sensitizations to mould and food allergens were most often documented, whilst clinically relevant respiratory allergy (as assessed by a physician) was recorded in 44.6% (bronchial asthma) and 66.8% (allergic rhinitis) of the patients.” Table 1 of this publication provided on overview on General patient characteristics at baseline including allergic sensitization (please see the following extract of Table 1 here): TABLE 1. (extract) (Table presented.) Additionally, allergic sensitization was commented in the discussion: ‘Surprisingly, in the TREATgermany baseline population allergic sensitization to mould and food allergens was most often documented’. (…) ‘Whilst these results support studies reporting a higher rate of “self-diagnosis” with respect to food allergy than can be confirmed by evidence-based diagnostic methods,² this finding demonstrated a substantial need for facilitating patient empowerment and access to specific health care for evidence-based allergy diagnosis.³ However, for the registry, allergic sensitization was assessed by the physicians. Here, it must be critically remarked that this information may be based on the patient statement in addition to IgE results. Regarding this issue, such a lack of clarity of the TREATgermany questionnaire remains to be solved in the future’. It has now been remarked that a mistake has been made here. The assignment ‘yes’ and ‘no’ was made the other way round. Indeed, these corrected data are much better consistent with previous publications on the sensitization profiles in adult patients with AD. In consequence, the sections listed above have to be changed as proposed here: Results section: “With regard to allergies, allergic sensitizations to pollen and house dust mite were most often documented, whilst clinically relevant respiratory allergy (as assessed by a physician) was recorded in 44.6% (bronchial asthma) and 66.8% (allergic rhinitis) of the patients.” TABLE 1 (extract) (Table presented.) DISCUSSION As expected, in the TREATgermany, baseline population allergic sensitization to pollen and house dust mite was most often documented. ‘(…) With a percentage of 40% our results further support studies reporting a higher rate of “self-diagnosis” with respect to food allergy than can be confirmed by evidence-based diagnostic methods.² This finding demonstrated a substantial need for facilitating patient empowerment and access to specific health care for evidence-based allergy diagnosis.³ However, for the registry, allergic sensitization was assessed by the physicians. Here, it must be critically remarked that this information may be based on the patient statement in addition to IgE results. Regarding this issue, such a lack of clarity of the TREATgermany questionnaire remains to be solved in the future’.
