Core Tip

Core tip: The CALM trial reported that a tight control of inflammation achieved better outcomes than conventional monitoring, but did not explore specifically the value of each biomarker. In this multicentre study, we investigated the performances of Crohn’s disease (CD) activity index (CDAI), C-reactive protein (CRP) and faecal calprotectin (Fcal) variation, alone or combined, after 12 wk of anti-tumor necrosis factor (TNF) therapy to predict corticosteroids-free remission (CFREM) at one year, in CD patients treated with anti-TNF. We showed the complementarity of the variation of CDAI, CRP and Fcal after anti-TNF induction therapy, to predict CFREM at one year, and confirmed that Fcal was the most effective predictor among these three markers.
