研究目的:

主要目的:评估二代非镇静抗组胺药物联合苯磺酸克利加巴林,相较于二代非镇静抗组胺药物联合一代镇静抗组胺药物治疗,在成人结节性痒疹(PN)相关瘙痒和原因不明性慢性瘙痒(CPUO)中的有效性和安全性。 次要目的:(1)分析PN和CPUO患者治疗前后的瘙痒特征变化,进而探索与疾病治疗转归及预后相关的神经递质等神经免疫标志物;(2)分析PN和CPUO患者治疗前后神经免疫标志物与瘙痒相关评分、睡眠评分及情绪评分之间的相关性,初步探索治疗预后相关的神经免疫机制。  

Objectives of Study:

Primary objective: To evaluate the efficacy and safety of second-generation non-sedating antihistamines combined with clindamycin besylate compared to second-generation non-sedating antihistamines combined with first-generation sedating antihistamines in the treatment of pruritus related to PN and CPUO in adults. Secondary objectives: (1) To analyze changes in pruritus characteristics before and after treatment in patients with PN and CPUO, and to explore neuroimmune markers such as neurotransmitters related to disease treatment outcomes and prognosis; (2) To analyze the correlation between neuroimmune markers and pruritus-related scores, sleep scores, and mood scores before and after treatment in patients with PN and CPUO, and to preliminarily explore neuroimmune mechanisms related to treatment prognosis.
