Therapy of ulcerative colitis: state of the art

Abstract

Advances in conventional therapy, novel targets and therapeutic goals are the highlights of treatment for ulcerative colitis in the last year. There have also been disappointments. This review summarizes the highs and lows, with an emphasis on strategy as opposed to seeking the newest treatment option. In conventional therapy, once daily therapy for 5-aminosalicylic acid is generally sufficient. Furthermore, a new 5-aminosalicylic acid (mesalamine MMX) has been released that effectively induces and maintains remission. There have been reappraisals of immunomodulators and further evaluation of (yes, now conventional!) infliximab for ulcerative colitis. Opportunistic infections, long-term outcomes and the burden of disease are being characterized. New therapeutic targets included an antibody against T cells (anti-CD3), but trials on visilizumab for acute severe colitis have been suspended. T-cell costimulation, phosphatidylcholine to promote barrier function, new anti-tumour necrosis factor agents, B-cell (anti-CD20) depletion and complementary therapies represent new therapeutic horizons. International agreement is needed on activity indices, definitions of remission, therapeutic goals (including mucosal healing) and outcomes that matter to patients, so that trials can be compared. Advances will take time to alter mainstream practice, but 2007-2008 is the year of organized strategies, with European, American and British guidelines on ulcerative colitis published or in press. These should be the platform for better outcomes for patients.
