The majority (70%, 88/125) of these individuals had normal BST levels. Notably, half of the <i>KIT</i>-positive patients receiving honeybee venom immunotherapy had SAEs during treatment (48%, 18/37; <i>p</i> = 0.0136), and the <i>KIT</i> p.D816V allele burden was higher than 0.01% in the majority of those patients (61%, 11/18). Furthermore, a significant difference was observed between <i>KIT</i>-positive and <i>KIT</i>-negative patients treated with VIT in the past and who experienced a recurrent reaction to a sting after treatment termination (VIT failure). <i>KIT</i>-positive patients with VIT failure had a higher allele burden than those with successful VIT (80% vs. 40% with a <i>KIT</i> p.D816V higher than 0.01%; <i>p</i> = 0.0019). <i>KIT</i> p.D816V was a predictor of SAEs during honeybee VIT (univariate; OR = 2.43, <i>p</i> = 0.012/multivariate; OR = 2.26, <i>p</i> = 0.033) and a strong predictor of VIT failure in patients treated with wasp venom (univariate; OR = 4.1, <i>p</i> = 0.002/multivariate; OR = 3.54, <i>p</i> = 0.008).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Our study revealed the high clinical relevance of <i>KIT</i> p.D816V detected in PBL. <i>KIT</i> p.D816V was a significant predictor of SAEs during honeybee VIT and a significant predictor of VIT failure after completing wasp VIT.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10334,"journal":{"name":"Clinical and Translational Allergy","volume":"15 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clt2.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
