Effective use of switching biologics for ulcerative colitis complicated with pyoderma gangrenosum and primary sclerosing cholangitis.

BMJ Case Rep 2021 May 6;14(5). Epub 2021 May 6.

Gastroenterology, Showa University Fujigaoka Hospital, Yokohama, Japan.

Although prednisolone, granulocyte/monocyte apheresis, calcineurin inhibitor and anti-tumour necrosis factor (TNF) therapy are generally used, no treatment strategy for inflammatory bowel disease complicated with pyoderma gangrenosum (PG) has been established yet.
