Allergy Testing of Soldiers Prepared for International Mission
The goal of this prospective mono centric study is to identify relevant commercially available allergen extracts for allergy testing in soldiers prepared for international mission.
Participants will receive a skin prick test with the skin prick automated test device including 22 allergens and 2 controls on both forearms.

Healthy volunteers accepted: Yes
Only the study team can determine whether someone qualifies for participation.
Inclusion criteria
- Adult military personnel (18-65y) will be included. Soldiers with and without previous exposure to allergens in the regions of interest will be included. Soldiers who are performing desk tasks and not selected for international missions will serve as controls.
Exclusion criteria
- Skin pathology like chronic or exuberant urticaria, dermographism, chronic dermatitis that needs daily treatment
- Use of antihistaminic medication < 7 days before the start of the study
- Use of tricyclic antidepressants (antihistamine activity) < 7 days before the start of the study
- Use of topical corticoids on the forearm < 7 days before the start of the study
- Use of Omalizumab < 6 months before the start of the study
- Pregnancy: there is a remote possibility of inducing a systemic allergic reaction that could induce uterine contractions or necessitate the use of epinephrine (thought to cause constriction of the umbilical artery).
Treatment and study plan
Skin Prick Automated Test
DeviceA skin prick automated test will be performed in each participant.
Primary outcomes
-
Allergens with positive skin reaction
Time frame: baseline
Positive skin reactions of top ranked allergens required to identify 95% of sensitised individuals
Secondary outcomes
-
Self-reported allergic diseases
Time frame: baseline
Percentage of soldiers with self-reported allergic diseases derived from questionnaire
-
Work Performance & Activity Impairment
Time frame: baseline
Total score of Work Performance & Activity Impairment questionnaire, 0-100%, higher score means worse outcome
