Abstract

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by the formation of nodules, abscesses, and fistulae at intertriginous sites. The skin-gut axis is an area of emerging research in inflammatory skin disease and is a potential contributory factor to the pathogenesis of HS. A total of 59 patients with HS provided fecal samples and nasal and skin swabs of affected sites for analysis. A total of 30 healthy controls provided fecal samples, and 20 healthy controls provided nasal and skin swabs. We performed bacterial 16S ribosomal RNA gene amplicon sequencing on total DNA derived from the samples. Microbiome alpha diversity was significantly lower in the fecal, skin, and nasal samples of individuals with HS, which may be secondary to disease biology or related to antibiotic usage. Ruminococcus gnavus was more abundant in the fecal microbiome of individuals with HS, which is also reported in Crohn's disease, suggesting comorbidity due to shared gut microbiota alterations. Finegoldia magna was overabundant in HS skin samples relative to that in the healthy controls. It is possible that local inflammation is driven by F. magna by promoting the formation of neutrophil extracellular traps. These alterations in both the gut and skin microbiome in HS warrant further exploration, and therapeutic strategies, including fecal microbiota transplant or bacteriotherapy, could be of benefit.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
