Core Tip

Core Tip: Previous investigations, contraposing Crohn’s disease patients under infliximab (IFX) maintenance therapy, have indicated that higher IFX trough levels (ITLs) were associated with sustained drug response and clinical remission in inflammatory bowel disease patients, while lower ITLs were linked to secondary unresponsiveness of IFX. Currently, endoscopic remission or mucosal healing has been considered the main goal of biological therapy. Our study manifested that Crohn’s disease patients with higher levels of IFX blood concentration and lower levels of inflammatory biomarkers tended to have a better long-term endoscopic prognosis. Combining ITL, fecal calprotectin and C-reactive protein monitoring was helpful for the timely adjustment of IFX treatment strategy.
