Brief Summary:
It is a randomized, single-center, controlled trial to evaluate the effectiveness of oral immunotherapy with cashew protein compared with standard treatment (elimination diet) in pediatric patients with cashew allergy.
Detailed Description:
According to Polish data, in the population of children suspected of food allergy, cashew was the third nut found to be allergic, after peanut and hazelnut. Allergic reactions to nuts can be severe and life-threatening, making it challenging to avoid hidden sources of the allergen.
An effective and safe alternative to allergen avoidance strategies may be the use of oral specific immunotherapy.
In this study 39 children, aged 4 to 17 years with a diagnosis of IgE-dependent allergy to cashew, confirmed by an open oral provocation test (OFC; the first provocation before starting oral desensitization), will be randomly (2:1) assigned to two groups. The first group will be desensitized with a maintenance dose - 1200mg of cashew protein, while the second group - the control group - will be offered standard management - avoidance of cashew consumption.
Patients in the control group will be offered immunotherapy at the end of the study if its effectiveness is confirmed.
The desensitization procedure was planned in accordance with the guidelines for immunotherapy in food allergy of the European Academy of Allergology and Clinical Immunology.
The source of cashew protein is flour. The first dose of immunotherapy is given to patients in the intervention group in the hospital ward. The size of the initial dose depends on the symptom-triggering dose during the initial oral food provocation with cashew protein.
Every 2 weeks in the hospital setting, another higher dose of cashew protein will be given to the child. The requirement for increasing the dose of cashew is to achieve full tolerance of the previous dose. The maximum duration of this phase is 60 weeks.
After the maximum dose is tolerated, desensitization will continue for 12 weeks - the maintenance phase of desensitization.
The maintenance dose is 1200mg of cashew protein. The duration of the maintenance phase is 12 weeks (+/-3 weeks). After 12 weeks +/-3 weeks of maintenance dose, OFC and cashew protein tolerance assessment will be performed. Confirmation of complete cashew tolerance is the tolerance of a dose of 4043mg of cashew protein. Primary outcomes include the proportion of participants tolerating a single dose of 4043mg cashew protein during the final oral food challenge. Secondary outcomes assess adverse events, changes in immunological parameters, and the maximum tolerated doses of cashew protein in each group.
