Sustained Unresponsiveness (SU) to Cashew Nut Protein Following Oral Allergen-Specific Immunotherapy

After 8 months of continued oral immunotherapy (OIT) with cashew nuts, patients will undergo hospital-based assessments, including skin prick testing, laboratory evaluations, and an open Oral Food Challenge (OFC) to assess desensitization. Patients who had a negative OFC after 3 months in the initial phase-confirming desensitization-will skip the pre-break OFC and proceed directly to the next stage. Following a 4-week interruption in OIT, patients will return for a final hospital visit, during which a concluding OFC will be conducted to evaluate sustained unresponsiveness. Additional laboratory tests and skin prick testing will also be performed during this visit.
