Management of Acute Severe Colitis in the Era of Biologicals and Small Molecules

Acute severe ulcerative colitis (ASUC) is a medical emergency which occurs in about 20%-30% of patients with ulcerative colitis during their lifetime, and does carry a mortality risk of 1%. The management of inflammatory bowel diseases has evolved with changes in objective patient monitoring, as well as the availability of new treatment options with the development of new biological and small molecules; however, data is limited regarding their use in the context of ASUC. This review aims to discuss the emerging data regarding biologicals and small molecules therapies in the context of ASUC.
