BACKGROUND
Prurigo nodularis (PN), while rare, presents significant clinical challenges due to its diverse pathogenesis and presentation. Effective therapy recommendations for PN remain limited. Upadacitinib, an oral highly selective type 1 Janus-associated kinase (JAK, Intracellular tyrosine kinases that phosphorylate cytokine receptors). Inhibitor plays an excellent role in alleviating itching in atopic dermatitis (AD). This is a report on the treatment of PN with upadacitinib, which offers a new option for refractory PN.
CASE PRESENTATION
We share our successful treatment experience of upadacitinib on a 43-year-old female patient with refractory PN failing to conventional therapies. She showed significant improvement at the follow-up visits and no obvious adverse effects happened. We also reviewed published case reports of PN patients and PN-related review researches and made a comprehensive discussion of the potential mechanism of JAK1 inhibitors in treating PN.
CONCLUSION
Upadacitinib may be a safe and potent alternative for patients with refractory PN.
背景
结节性痒疹（PN）虽罕见，但因其发病机制和表现多样，带来了重大的临床挑战。针对PN的有效治疗建议仍然有限。乌帕替尼是一种口服的高选择性1型 Janus 相关激酶（JAK，磷酸化细胞因子受体的细胞内酪氨酸激酶）抑制剂，在缓解特应性皮炎（AD）瘙痒方面发挥着出色作用。这是一篇关于用乌帕替尼治疗PN的报告，为难治性PN提供了新的选择。
病例报告
我们分享了乌帕替尼治疗一名43岁难治性PN女性患者的成功经验，该患者对传统疗法无效。随访时她有显著改善，且未发生明显不良反应。我们还回顾了已发表的PN患者病例报告和PN相关综述研究，并对JAK1抑制剂治疗PN的潜在机制进行了全面讨论。
结论
对于难治性PN患者，乌帕替尼可能是一种安全有效的替代药物。
