Transepidermal Water Loss as a Predictor for Severe Allergic Reactions in Oral Food Challenges
In Brief
A clinical study evaluating Transepidermal water loss (TEWL) monitor and stopping rules and Monitor (TEWL) without stopping rules for Anaphylaxis Food. Completed, enrolled 51 participants across 1 site.
Detailed Summary
This research study is testing a new way to look for the early stages of anaphylaxis. Eligible participants will have a small monitor (transepidermal water loss) placed on the forearm during a food challenge (for peanut allergies). This monitor continuously records the amount of water lost through the skin. In a previous study the team learned what values are associated with an anaphylactic reaction. These values are called "stopping rules." This study is looking at whether it can use these new stopping rules to end the oral food challenge before a person may show any symptoms.

Timeline
Interventions
The oral food challenge will be done as usual, and participants will wear the TEWL monitor. The research food allergy nurse and doctor will also be looking for signs and symptoms of an allergic reaction. The research study coordinator will be watching the TEWL numbers. If they numbers match the stopping rules, they will tell the doctor and the oral food challenge will be over.
