Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the investigators want to find out whether a specific medication commonly used for severe allergic reactions is really necessary. When children have allergic reactions to foods, they are often given medications to relieve the symptoms. In addition to adrenaline and antihistamines, steroids are frequently administered in German-speaking Switzerland. However, it is unclear whether steroids are really helpful in this situation. To investigate this, the investigators are comparing two groups: one group receives additional steroids, and the other does not. Which treatment a participant receives is decided randomly, like flipping a coin. The study takes place during a pre-scheduled provocation test at the clinic. If an allergic reaction occurs, the usual emergency medications will be administered. Doctors will closely monitor how the reaction develops. No additional tests or visits are required. The results of this study could help improve allergy treatment in the future.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Antihistamines plus oral steroids

Participants receive oral antihistamines plus oral systemic corticosteroids for treatment of allergic reactions occurring during the oral food challenge. Intramuscular adrenaline may be administered as rescue medication if clinically indicated.

Group Type ACTIVE_COMPARATOR

Antihistamines

Intervention Type DRUG

Oral administration of antihistamines for treatment of allergic symptoms during the oral food challenge.

Systemic corticosteroids

Intervention Type DRUG

Oral administration of systemic corticosteroids as adjunctive treatment of allergic reactions during the oral food challenge.

Adrenaline (rescue medication)

Intervention Type DRUG

Intramuscular administration of adrenaline as rescue treatment for severe allergic reactions (anaphylaxis), administered as clinically indicated.

Antihistamines only (no steroids)

Participants receive oral antihistamines without systemic corticosteroids for treatment of allergic reactions occurring during the oral food challenge. Intramuscular adrenaline may be administered as rescue medication if clinically indicated.

Antihistamines

Intervention Type DRUG

Oral administration of antihistamines for treatment of allergic symptoms during the oral food challenge.

Adrenaline (rescue medication)

Intervention Type DRUG

Intramuscular administration of adrenaline as rescue treatment for severe allergic reactions (anaphylaxis), administered as clinically indicated.
