Evolving Concepts in Psoriasis: Special Considerations for Patients With Skin of Color, Skin Barrier Dysfunction, and the Role of Adjunctive Skin Care.

Abstract

Despite considerable advances in our understanding of the pathogenesis and treatment of psoriasis, data pertaining to racial/ethnic variations, effects on barrier function, and the potential role of adjunctive skin care are relatively limited. Knowledge gaps in the clinical presentation, quality-of-life impact, and approach to treating psoriasis in patients with skin color contribute to disparities in care. In addition, small studies suggest that using skincare products can reduce psoriasis symptoms, improve barrier function, and result in higher patient satisfaction, yet patients with psoriasis may underuse skincare products. This manuscript seeks to offer insights into these knowledge gaps and their potential treatment implications. A structured literature search followed by a panel discussion and an online review process explored best clinical practices in treating psoriasis patients with skin of color and providing expert guidance for skincare use, including gentle cleansers and moisturizers. Racial/ethnic differences in genetic factors, clinical presentation, and disease burden in psoriasis have been reported. Underrecognition of these differences contributes to racial/ethnic health disparities for psoriasis patients in the US. Several studies have shown a greater quality-of-life impact with psoriasis among patients with skin of color. Although the published data are limited, some studies have identified differences in skin barrier properties and suggest a role for adjunctive skin care in the management of psoriasis. Further study is needed to understand racial/ethnic population variations in psoriasis and develop strategies to reduce disparities in care. Addressing alterations in skin barrier function observed in psoriasis may help to improve treatment outcomes and patient satisfaction. J Drugs Dermatol. 2022;21(10):1054-1060. doi:10.36849/JDD.7090.
