Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective:In order to investigate the genetic diversity of mitochondrial cytochrome b (Cytb) gene of Taenia asiatica ( T. asiatica) in Dali Bai Autonomous Prefecture (Dali Prefecture), Yunnan Province. Methods:From May 2019 to August 2021, a total of 131 samples of Taenia were collected from patients admitted to the Dali Prefecture Institute of Schistosomiasis Control, involving five locations (i.e., five groups), including Dali City (58 samples), Weishan Yi and Hui Autonomous County (Weishan County, 14 samples), Midu County (18 samples), Yangbi Yi Autonomous County (Yangbi County, 24 samples) and Eryuan County (17 samples). Primers were designed based on mitochondrial Cytb gene sequence, and part of the Cytb gene sequence was amplified by PCR, then sequenced and homology comparisons were performed. MEGA 7.0 and DNASP 5.10.01 were used to analyze the measured sequence, and data such as base composition, genetic distance, genetic diversity parameters, genetic differentiation index and gene flow were obtained. Results:The amplified fragments of Cytb gene in 131 samples of Taenia were 235 bp. After homology comparisons, they were all T. asiatica. The average contents of A, T, G and C bases were 23.8%, 42.3%, 24.0% and 9.9%, respectively. Of the 131 samples of T. asiatica, 12 haplotypes were defined. The haplotype diversity and nucleic acid diversity were 0.295 9 and 0.006 0, respectively. The ranges of genetic differentiation index and gene flow among the five groups were-0.053 00 to 0.050 40 and 4.710 31 to 162.087 66, respectively. The genetic distance between the five groups ranged from 0.003 5 to 0.009 0, of which the genetic distance between Midu County and Weishan County was the largest, and the genetic distance between Dali City and Yangbi County was the smallest. Conclusions:The mitochondrial Cytb gene of T. asiatica in Dali Prefecture has rich genetic diversity. There is frequent gene exchange among the five groups, and no significant genetic differentiation has been formed.
