Clinical Trial Summary

Oral immunotherapy(OIT) is effective in desensitized food allergy. OIT protocols are not standardized, and a wide heterogeneity exists in the literature . So the purpose of our study is to compare short term unresponsiveness rate between once daily dose and four times/week dose during one year maintenance phase of wheat OIT

Description:

All subject in this study were patients with history of IgE mediated wheat allergy and positive OFC test. All of them received wheat OIT and reached target maintenance dose of wheat OIT.

The primary outcome was to compare short term unresponsiveness rate between once daily dose and four times/week dose during one year maintenance phase of wheat OIT. Other outcomes were collected during the projected such as blood and skin examination for immunologic parameter, changing in Body weight, WA, WH and BMI, compliance, adverse reactions, rates of medication used during OIT and quality of life

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Short term unresponsiveness rate	Short term unresponsiveness rate between once daily dose and four times/week dose .during maintenance phase of wheat OIT.; Short term unresponsiveness means patients who pass the oral food challenge test after stopping oral immunotherapy for a short period	13 months
Secondary	Specific IgE to wheat	Specific IgE to wheat	13 months
Secondary	Specific IgG4 to wheat	Specific IgG4 to wheat	13 months
Secondary	Changing in Body weight	Changing in Body weight in kilograms	13 months
Secondary	Compliance	Compliance of wheat ingestion (group A: every day, groupB: 4 days/weeks). Compliance can be calculated by dividing the number of days on which wheat is actually ingested by the total number of days prescribed for wheat consumption.	12 months
Secondary	Adverse reactions	Adverse reaction during treatment will be recorded by using WAO systemic allergic reaction grading system	13 months
Secondary	Quality of life by using FAQLQ-PF	Quality of life before and after enrollment by using FAQLQ-PF	13 months
