| Popis: | Objective We have recently reported that a new regimen of short-term oral immunotherapy (OIT) with the Cry j1–galactomannan conjugate for Japanese cedar pollinosis (JCP) is effective to the improvement in the symptoms and medication use during the pollen season and relatively safe. The effect of OIT on quality of life (QOL) of JCP patients has not been assessed. Therefore, we evaluated for the first time the effect of OIT on QOL during the Japanese cedar/cypress pollen season. Methods A prospective, randomized, open-label trial was conducted over a period of 4 months. Participants were randomly divided into two groups. The OIT and control groups comprised 23 and 24 subjects, respectively. The build-up phase was initiated 1 month before the expected pollen season. The maintenance phase was continued for 51 days during the peak of the cedar pollen season. The QOL score in the Japan Rhinoconjunctivitis Quality of Life Questionnaire (JRQLQ) No. 1 and visual analog scale (VAS) throughout the pollen season were evaluated. Results Participants receiving OIT showed significant improvements in the total QOL score and VAS throughout the pollen season compared with the control group. In addition, the mean total QOL score and VAS correlated in both groups during the pollen season. Conclusion The new regimen of short-term OIT using the Cry j1–galactomannan conjugate results in meaningful improvements in QOL of JCP patients. Our findings suggest that short-term OIT using allergen–galactomannan conjugates, as well as sublingual and subcutaneous immunotherapy, improves QOL of patients with pollinosis. The study was registered in UMIN-CTR (UMIN000013408) as the name of “a prospective, randomized, open study of oral Cry j1–galactomannan conjugate immunotherapy for Japanese cedar pollen allergy”. |
