摘要

Introduction

Chronic hand eczema (CHE) remains difficult to treat, particularly in patients unresponsive or intolerant to topical corticosteroids. Although topical delgocitinib, the first topical JAK inhibitor approved for CHE, provides a steroid-free alternative, comparative real-world data versus localized cream psoralen–ultraviolet A (PUVA) are missing. This retrospective real-world study compared the short-term effectiveness and patient-reported outcomes of topical delgocitinib and localized cream PUVA in patients with CHE under routine-care conditions.

Methods

This retrospective cohort study analyzed anonymized routine-care data of patients with moderate-to-severe CHE treated between 2024 and 2025 at a tertiary center. Patients received topical delgocitinib twice daily or localized cream PUVA with as-needed topical corticosteroids (TCS). Twenty-two patients per group completed 12 weeks of delgocitinib or 20–25 PUVA sessions plus TCS (per-protocol). Disease severity (Physician’s Global Assessment, PGA), quality of life (Dermatology Life Quality Index, DLQI), and symptom numerical rating scales (pruritus, pain, sleep disturbance) were assessed at baseline and treatment end.

Results

Both therapies significantly improved all endpoints (p < 0.001). Median DLQI improvement was 10 with delgocitinib versus 7.5 with PUVA (p = 0.15). PGA 0/1 responses were 82% vs 73% (p = 0.72). DLQI improvement ≥ 4 points occurred in 91% vs 77% (p = 0.41). Relapses were more frequent after PUVA. Two delgocitinib non-responders improved with alitretinoin. Most delgocitinib responders continued proactive low-frequency use to maintain remission; one remained clear 3 months after stopping treatment.

Conclusion

Delgocitinib and PUVA provided comparable short-term clinical efficacy in CHE, with a numerically greater DLQI reduction for delgocitinib. Proactive delgocitinib maintenance may help sustain disease control. Subtype-adapted treatment strategies could further optimize outcomes.
