Research progress of gut microbiome in the treatment of psoriasis
Psoriasis is a chronic,recurrent,systemic inflammatory skin disease that is immune-media-ted.The balance and communication between the intestinal microbiota and its metabolites and the host play an important role in maintaining the body's normal functions,such as immune homeostasis and vitamin synthe-sis.Recent studies have found that compared with the healthy individuals,the psoriasis patients have experi-enced significant changes in the abundance and diversity of intestinal microbiota,including an imbalance in in-testinal microbiota,reduced production of short-chain fatty acids(SCFAs),and abnormal Firmicutes/Bacte-roidetes(F/B)ratio.The gut microbiota also changed after systematic medication treatment,biologic agents treatment and small molecule chemotherapy,indicating that the gut microbiota could be a potential biomarker for assessing treatment efficacy.The relationship between psoriasis and gut microbiota is not fully under-stood,and further research is needed.
