Standardizing Hidradenitis Suppurativa Skin Microbiome Research: The Methods Matter.

Cutaneous dysbiosis is implicated in hidradenitis suppurativa (HS) pathogenesis. Previous studies reveal skin microbiota shifts in HS lesional skin. In their report, Riverain-Gillet et al. (2020) extended these findings and reported skin microbiota shifts in unaffected HS skinfolds as well. Their study suggests that skin microbial shifts may precede clinical lesions and draws attention to study methods important for skin microbiome research.
