Summary

This study is a long-term follow-up of participants from the randomized controlled trial (RCT) "Efficacy and Safety of Low-Dose Sesame Oral Immunotherapy in Pediatric Patients", NCT06261554. At the end of the original RCT all participants will undergo an open Oral Food Challenge (OFC) to assess desensitization after 3 months on the maintenance dose of OIT. Patients who have completed the first part of the study will be invited to the current part of the project:

* First arm (initial experimental group) - patients will continue oral immunotherapy (OIT) with low dose of sesame protein (300mg) for the next 8 months (+/- 3 weeks).
* Second arm (initial control group - one year on a sesame elimination diet) - patients will begin OIT following the protocol used in the first part of the study (RCT). Upon completion of this initial phase, they will continue immunotherapy for an additional 8 months (+/- 3 weeks).

After an additional 8 months (+/- 3 weeks) of OIT, all study participants will undergo a 4-week cessation of treatment, followed by an open Oral Food Challenge (OFC) to assess the development of sustained unresponsiveness (SU).

OIT with low dose sesame protein

After 8 months of continued low-dose sesame OIT, patients will undergo hospital-based assessments, including skin prick testing, laboratory evaluations, and an open Oral Food Challenge (OFC) to evaluate desensitization. Patients who had a negative OFC after 3 months in the initial phase of the study-and thus confirmed 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 assess sustained unresponsiveness. Additional laboratory tests and skin prick testing will also be performed at this visit.
