We report a 15-year-old female with severe PV who developed rituximab refractoriness after an initially effective response. Despite treatment with a combination of intravenous immunoglobulin, corticosteroid, and immunosuppressants, the patient failed to achieve disease control. Consequently, dupilumab, an interleukin-4 receptor α antagonist, was initiated on a biweekly regimen. Her lesions showed dramatic improvement, with the pemphigus disease area index (PDAI) reaching 0. Her anti-desmoglein 1 antibody level became negative, and T helper (Th)-2 inflammatory markers, including eosinophil count and immunoglobulin E (IgE) level, was normalized, allowing corticosteroid tapering after the 8th dose (last dose) of dupilumab. She has maintained complete remission for at least 28 weeks with regular follow-ups. We additionally propose possible mechanisms underlying rituximab refractoriness and how dupilumab modulates this treatment response.

This process results in the harmful effects of UV irradiation on skin cells, leading to alterations in the extracellular matrix, which consequently impacts the appearance and function of the skin. This review aims to elucidate how bioactive compounds from medicinal plants counteract UV-induced damage, as identified by current mechanistic and molecular studies. Over the past few decades, medicinal plants have garnered increasing attention for their potential therapeutic benefits in treating various human diseases. Numerous studies have explored the anti-photoaging properties of herbal remedies, revealing that various active compounds, extracts, and combinations of medicinal plants can mitigate photoaging in different skin cells through diverse signaling pathways. Compared to synthetic agents, herbal remedies offer lower toxicity profiles and are often perceived as safer alternatives, making them attractive options for long-term skin care and photoaging prevention. These findings suggest that herbal plants can reduce UV-induced skin damage primarily by inhibiting the production of reactive oxygen species (ROS), matrix metalloproteinases (MMPs), and inflammatory mediators, while simultaneously promoting collagen synthesis. The underlying mechanisms of these effects are associated with key cellular pathways, including MAPK, NF-κB, Nrf2, and TGF-β/Smad. These findings suggest that herbal plants can reduce UV-induced skin damage by inhibiting reactive oxygen species (ROS), matrix metalloproteinases (MMPs), and inflammatory mediators, while promoting collagen synthesis.
