| 6 | Combined evaluation of biomarkers as predictor of maintained remission in Crohn's disease显示文摘BACKGROUND The individual performances and the complementarity of Crohn's disease(CD)activity index(CDAI), C-reactive protein(CRP) and faecal calprotectin(Fcal) to monitor patients with CD remain poorly inves-tigated in the era of 'tight control'and 'treat to target' strategies.AIM To assess CDAI, CRP and Fcal variation, alone or combined, after 12 wk(W12) of anti-tumor necrosis factor(TNF) therapy to predict corticosteroids-free remission(CFREM = CDAI < 150, CRP < 2.9 mg/L and Fcal < 250 μg/g with no therapeutic intensification and no surgery) at W52.METHODS CD adult patients needing anti-TNF therapy with CDAI > 150 and either CRP >2.9 mg/L or Fcal > 250 μg/g were prospectively enrolled.RESULTS Among the 40 included patients, 13 patients(32.5%) achieved CFREM at W52. In univariable analysis, CDAI < 150 at W12(P = 0.012), CRP level < 2.9 mg/L at W12(P = 0.001) and Fcal improvement at W12(Fcal < 300 μg/g; or, for patients with initial Fcal < 300 μg/g, at least 50% decrease of Fcal or normalization of Fcal(< 100 μg/g)(P = 0.001) were predictive of CFREM at W52. Combined endpoint(CDAI < 150 and CRP ≤ 2.9 mg/L and FCal improvement) at W12 was the best predictor of CFREM at W52 with positive predictive value = 100.0%(100.0-100.0)and negative predictive value = 87.1%(75.3-98.9). In multivariable analysis, Fcal improvement at W12 [odd ratio(OR) = 45.1(2.96-687.9); P = 0.03] was a better predictor of CFREM at W52 than CDAI < 150 [OR = 9.3(0.36-237.1); P = 0.145]and CRP < 2.9 mg/L(0.77-278.0; P = 0.073).CONCLUSION The combined monitoring of CDAI, CRP and Fcal after anti-TNF induction therapy is able to predict favorable outcome within one year in patients with CD. | Elisa Sollelis Régine Minet Quinard Guillaume Bouguen Marion Goutte Félix Goutorbe Damien Bouvier Bruno Pereira Gilles Bommelaer Anthony Buisson | 2019 | World Journal of Gastroenterology2019，25，19： | 1 |
