Wheat oral immunotherapy: desensitization and reaction risks
What it found
Wheat oral immunotherapy often desensitizes people with wheat allergy, especially with higher maintenance doses taken for longer.
It can also cause allergic reactions, including anaphylaxis, often when something like exercise is involved.
What they found
Studies in people
Desensitization usually works
Most wheat oral immunotherapy regimens led to successful desensitization in people. Success was more likely when people took higher maintenance doses for longer periods.
Reactions can occur
Wheat oral immunotherapy can cause allergic reactions, including anaphylaxis. More severe reactions often had an augmenting factor such as exercise.
Lower doses, fewer reactions
Lower maintenance doses were likely linked to less severe reactions. Changing the food or adding other treatments may also lower the risk of reactions.
Sustained unresponsiveness unclear
Only a small number of studies have looked at whether people stay desensitized after stopping treatment.
Other findings
Trial limits
The trials were generally small, which affected the mix of patients studied. There was also little standardization of how success and safety were measured, making it hard to compare trials directly.
What the authors conclude
“WOIT trials are ongoing and will optimize updosing protocols and maintenance doses to improve efficacy and safety.”
Also in their conclusions
- They say wheat oral immunotherapy trials are ongoing and will refine dosing schedules and maintenance doses to improve how well it works and how safe it is.
How it was done
Food allergy is becoming more common worldwide, so more attention is being paid to how specific food allergies are managed.
The authors reviewed human trials of wheat oral immunotherapy, including one multicenter double-blind randomized controlled trial, one randomized noncontrolled trial, and several smaller nonrandomized clinical trials.
What it can’t tell you
- We summarised it from the abstract only.
- The trials were small and used different ways to measure success and safety, so it is hard to compare them directly.
- Only a few studies looked at whether the effect lasts after treatment stops.
