Brief Summary

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

The aim of the study was to describe an intensive ultra rush (UR) protocol of raw Golden apple (RGA) reintroduction in 28 in-patients, show the protocol's tolerance and the patients' follow-up at 2 months and 1 year. Patients with oral allergic syndrome (OAS) having resulted in raw fruits eviction were admitted to day hospital between June 1 2016 and October 31 2017.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this study was to describe an intensive ultra rush (UR) protocol of raw Golden apple (RGA) reintroduction in 28 in-patients, show the protocol's tolerance and the patients' follow-up at 2 months and 1 year. Patients with oral allergic syndrome (OAS) having resulted in raw fruits eviction were admitted to day hospital between June 1 2016 and October 31 2017.

Methods : Patients were included during the first consultation, UR was performed with RGA in day hospital performed in two institutions, the Charcot clinic and the polyclinic of Beaujolais.

Starting with 1 gram (g) of food, then by regularly doubling dose from 2g to 128g, to reach a 255g cumulative dose in a 3 hour period.

During the the post hospitalization period, patients back home had to eat ½ RGA a day during one month, then 1 RGA a day during one month, together with other rosacea fruits resumption at the end of the 5th week if UR were performed between April 15th and July 15th. A synthesis consultation was made at two months and a telephone interview at one year.

Allergic patients to raw apple and birch

Single-group studies about 28 patients allergic to birch and no longer eating raw rosaceae for at least 6 months. Patients brought back into contact with this family of fruits via the raw golden apple according to an Ultra-Rush protocol.
