Conventional treatment of moderate-severe ulcerative colitis (UC) has resulted in only a limited therapeutic benefit. Advancing knowledge of UC pathogenesis and recent advances in biotechnology have led to the development of biological agents that selectively target individual inflammatory pathways. In particular, the role of tumor necrosis factor alpha (TNF-α) in UC pathogenesis has been clarified by serological and immunohistochemical studies in humans and by experimental models. Clinical efficacy of anti-TNF-α therapy with infliximab has been assessed in two large controlled trials, showing a good compromise between therapeutic gain and safety. The aim of this review is to provide an insight into the role of TNF-α and anti-TNF-α therapy in patients with UC and diverticular disease associated colitis.
