Background: Lipid transfer proteins (LTPs) syndrome is an important cause of multiple plant food allergy in the Mediterranean area. The effectiveness of sublingual immunotherapy (SLIT) with the LTP Pru p 3 extract has been little investigated in the real-world setting. This study aimed to investigate the outcome of Pru p 3 SLIT in real-life patients with LTP syndrome with/without concurrent reactions to peanut and/or nuts. Methods: This was a prospective real-life study including all patients diagnosed with LTP allergy and treated with Pru p 3 SLIT between 2011 and 2018 in a tertiary hospital in Spain. Patients underwent open oral food challenge (OFC) tests for unpeeled peach and nuts/peanuts 1 year after the treatment started to assess food tolerance. A control group of patients diagnosed with LTP allergy who refused treatment with immunotherapy were included. Severity of symptoms and diet avoidance was recorded in both groups. Results: Twenty-nine patients with a median age of 24.7 years (range 5.5–43.1) were included: 100% were allergic to fruit; 72%, to peanut and/or nuts; 19 had a history of severe systemic reactions. Seven patients discontinued therapy; 3 (10%), due to adverse events. One year after SLIT start, 16 (73%) patients had negative OFC to peach; 95%, after 2 years; 69% had negative OFC to nuts/peanuts. The control group included 13 patients: 53.8% experienced reactions with new foods; severity of symptoms increased significantly (p < 0.001), and diet restrictions were maintained in this group. Conclusions: SLIT with Pru p 3 shows a good safety profile, and avoid dietary restrictions in patients with LTP syndrome treated in the real-life setting. [ABSTRACT FROM AUTHOR] |
