Social, environmental and dietary changes are associated with the changes of disease spectrum in a country. Ulcerative colitis has become a commonly seen disease in China, probably due to extensive consumption of Western foods in recent years. Unfortunately, the etiology and pathogenesis of ulcerative colitis have not been clarified yet.

Findings presented at Digestive Disease Week® 2007 (DDW), from long-term extensions of the ACT trials (Active Ulcerative Colitis 1 & 2) show that subjects with moderately to severely active ulcerative colitis (UC) who had responded to REMICADE® (infliximab) in the blinded phase of the trials maintained improvement in their clinical symptoms for up to two years.
