Abstract

Background: Quality of life (QOL) is impaired in patients with food allergy and improves following oral immunotherapy (OIT). However, the treatment itself is prolonged and demanding. We examined changes in patient QOL during OIT for food allergy. Methods: The FAQLQ-PF was administered to children aged 4-12 years undergoing OIT for milk, peanut, or egg allergy, at the beginning and after 4 months of treatment. Patients were categorized as improved, unchanged, or diminished FAQLQ-PF (>0.5 point decrease, a change of ≤0.5 points, or >0.5 increase, respectively) and compared. Food-allergic patients not undergoing OIT served as controls. Results: The Food Anxiety, Social and Dietary Limitation, and total FAQLQ-PF scores improved significantly during the study period (P=.001, P=.018, and P=.01, respectively) in treated but not in control patients, while the Emotional Impact did not. The change in the FAQLQ-PF was independent of the maximal tolerated dose at baseline or following four months of treatment, the pace of dose increase, or the number or severity of reactions experienced. The total FAQLQ-PF score was inversely associated with the score at baseline on multivariate analysis (regression coefficient=−0.56, P<.001). That was driven primarily by improvement in QOL scores in patients with high score (worse QOL) at baseline. Some patients with low FAQLQ-PF score (better QOL) at baseline deteriorated. Conclusions: QOL of patients with food allergy improves in some but deteriorates in others during OIT. Patients with impaired QOL at baseline improve significantly despite the treatment burden. Some patients with better QOL at baseline might deteriorate during OIT.
