Abstract

Background: Some studies have established a link between gut microbiota, inflammatory proteins, and inflammatory dermatoses. However, the mediating role of inflammatory proteins in the gut-skin axis remains unclear.

Methods: Data on inflammatory proteins and gut microbiota were drawn from the GWAS catalog and MiBioGen consortium, with inflammatory skin disease data provided by the FinnGen consortium. Using genome-wide association studies (GWAS), we performed linkage disequilibrium score regression (LDSC) to assess genetic correlations and conducted a two-step Mendelian Randomization (MR) analysis to investigate circulating inflammatory proteins as potential mediators between gut microbiota and inflammatory dermatoses.

Results: MR analysis identified 38 gut microbiota and 23 inflammatory proteins associated with inflammatory skin diseases. After false discovery rate (FDR) correction, four gut microbiota taxa-Eubacterium fissicatena, Bacteroidaceae, Allisonella, and Bacteroides, remained statistically significant (OR = 1.32, 95% CI: 1.16-1.50, adjusted P = 0.007; OR = 2.25, 95% CI: 1.48-3.42, adjusted P = 0.026; OR = 1.42, 95% CI: 1.18-1.70, adjusted P = 0.014; OR = 2.25, 95% CI: 1.48-3.42, adjusted P = 0.013), with only IL-18R1 significantly associated with eczema (OR = 1.05, 95% CI: 1.03-1.08, adjusted P = 0.017). Further mediation analysis showed that IL-15RA mediated 11% of the pathway between Veillonellaceae and eczema, while FGF19 mediated 6% of the pathway between genus LachnospiraceaeUCG001 and psoriatic arthritis.

Conclusion: These findings provide potential targets for therapeutic interventions in inflammatory skin diseases.

期刊介绍： Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal. Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest. The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care. All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
