CLINICAL EFFICACY OF SUBLINGUAL IMMUNOTHERAPY IN THE SECOND TREATED YEAR FOR 133 PATIENTS WITH JAPANESE CEDAR POLLINOSIS IN 2016.

Abstract

The purpose of this study is to clear the clinical efficacy of SLIT in the second treated year by comparing with other therapies, such as subcutaneous immunotherapy (SCIT), or other pharmacotherapy. We started SLIT at our clinic in October-December, 2014. We compared the clinical efficacy in 2016, of 133 SLIT with 46 SCIT, 351 primary pharmacotherapy that started therapies before pollen dispersal, 221 pharmacotherapy that started therapies after pollen disposal, or 337 non-treatment. The clinical efficacy was evaluated with symptom scores and combined symptom-medication scores (SMS), symptoms of nose and eye by visual analog scale (VAS), quality of life (QOL) scores by Japanese rhino-conjunctivitis QOL questionnaire (JRQLQ No1). Fourteen cases by unknown reasons and 3 cases by inevitable reasons were dropped out for 2 years. Both SCIT and SLIT showed good clinical efficacy without significant difference in every assessment. Both SCIT and SLIT were significantly better than other pharmacotherapy in most assessment. Patients, whose symptom scores of nose and eye were 0 or 1 point without any rescue drugs, accounted for 26.3% of total SLIT. SLIT in the second treated year showed good clinical efficacy in reducing symptoms and SMS of JCP, and in improving QOL. SLIT was significantly effective compaired with other pharmacotherapies.
