Acquired reactive perforating collagenosis (ARPC) is a clinically challenging disease with an unclear pathogenesis.
To evaluate the efficacy and safety of dupilumab for the treatment of ARPC, and analyze the expression of type 2 inflammation-related molecules in ARPC lesions.
This retrospective cohort study included 20 patients with ARPC; 10 received dupilumab and 10 received conventional therapy. The efficacy and safety of dupilumab were evaluated at 12 weeks. Immunohistochemical and immunofluorescence analyses of T- and B-cell markers, and type 2 inflammation-related cytokines, were performed on skin samples from ARPC patients, atopic dermatitis (AD) patients, and healthy controls.
Significantly more patients showed improvements in the Investigator Global Assessment score (100% vs. 0%; p < 0.0001) and itching (90%/8.33%, P =.001) in the dupilumab group compared to the conventional group at 12 weeks. There were no adverse effects in the dupilumab group. The ARPC lesions showed enhanced dermal infiltration of CD3+ T-cells, with a predominance of Th2 cells, similar to AD lesions. IL-4 and IL-13 were co-localized with GATA3 in ARPC lesions.
Dupilumab improved ARPC charaterized with type 2 inflammation.
获得性反应性穿孔性胶原病(ARPC)是一种临床治疗具有挑战性的疾病,其发病机制尚不清楚。
评估度普利尤单抗治疗 ARPC 的疗效和安全性,并分析 ARPC 病变中 2 型炎症相关分子的表达。
本回顾性队列研究纳入了 20 例 ARPC 患者;其中 10 例接受度普利尤单抗治疗,10 例接受常规治疗。在 12 周时评估度普利尤单抗的疗效和安全性。对 ARPC 患者、特应性皮炎(AD)患者和健康对照者的皮肤样本进行 T 细胞和 B 细胞标志物及 2 型炎症相关细胞因子的免疫组化和免疫荧光分析。
与常规组相比,12 周时度普利尤单抗组患者的研究者全球评估评分(100% vs. 0%;p < 0.0001)和瘙痒(90%/8.33%,P =.001)改善更明显。度普利尤单抗组无不良反应。ARPC 病变表现出真皮内 CD3+T 细胞浸润增强,以 Th2 细胞为主,类似于 AD 病变。IL-4 和 IL-13 与 ARPC 病变中的 GATA3 共定位。
度普利尤单抗改善了以 2 型炎症为特征的 ARPC。
