Tofacitinib for Pityriasis Rubra Pilaris: A Case Report.

At present, we have entered the era of using biological agents and small molecule targeted drugs to treat diseases. Although there have been many reports of biological agents treating pityriasis rubra pilaris recently, the clinical application of the JAK inhibitors in the treatment of pityriasis rubra pilaris has been rarely reported, and there is a lack of evidence on the safety and efficacy of these drugs. We explore the use of the JAK inhibitor tofacitinib in the treatment of pityriasis rubra pilaris with significant efficacy and no significant side effects, providing new ideas for the clinical treatment of pityriasis rubra pilaris. We cover a case of pityriasis rubra pilaris treated with the JAK inhibitor tofacitinib, which showed significant efficacy without any adverse effects. This case report showed that the JAK inhibitor tofacitinib had significant clinical efficacy in the treatment of pityriasis rubra pilaris. We speculated that the treatment of pityriasis rubra pilaris with the JAK inhibitors may be related to blocking the activation of the JAK/STAT pathway, thereby blocking the high expression of cytokines IL-17, IL-12/IL-23, IL-23, TNF-α. The JAK inhibitor tofacitinib can become a new option for treating pityriasis rubra pilaris.
