Changing Patient Mindsets About Non-Life-Threatening Symptoms During Oral Immunotherapy: A Randomized Clinical Trial.
The journal of allergy and clinical immunology. In practice
BACKGROUND: Oral immunotherapy (OIT) can lead to desensitization to food allergens, but patients can experience treatment-related symptoms of allergic reactions that cause anxiety and treatment dropout. Interventions to improve OIT for patients are needed.OBJECTIVE: To determine whether fostering the mindset that non-life-threatening symptoms during OIT can signal desensitization improves treatment experience and outcomes.METHODS: In a randomized, blinded, controlled phase II study, 50 children/adolescents (28% girls, aged 7-17, M=10.82, SD=3.01) completed six-month OIT for peanut allergies. Patients and their parent(s) had monthly clinic visits at the Sean N. Parker Center for Allergy & Asthma Research between 1/5/2017-8/3/2017. All families received identical symptom management training. In a 1:1 approach, 24 patients and their families were informed that non-life-threatening symptoms during OIT were unfortunate side effects of treatment, and 26 patients and their families were informed that non-life-threatening symptoms could signal desensitization. Families participated in activities to reinforce these symptom mindsets.RESULTS: Compared to families informed that symptoms are side effects, families informed that symptoms can signal desensitization were less anxious (B=-0.46, 95% CI (-0.76 to -0.16), p=0.003), less likely to contact staff about symptoms (5/24[9.4%] vs. 27/154[17.5%] instances, p=0.036), experienced fewer non-life-threatening symptoms as doses increased (BInteraction=-0.54(-0.83 to -0.27), p<0.001), less likely to skip/reduce doses (1/26[4%] vs. 5/24[21%] patients, p=0.065), and showed greater increase in patient peanut-specific blood IgG4 levels (BInteraction=0.76(0.36 to 1.17), p<0.001).CONCLUSION: Fostering the mindset that symptoms can signal desensitization improves OIT experience and outcomes. Changing how providers inform patients about non-life-threatening symptoms is a promising avenue for improving treatment.
