| 2 | Endoscopic response to tumor necrosis factor inhibitors predicts long term benefits in Crohn's disease显示文摘BACKGROUND Identifying predictors of therapeutic response is the cornerstone of personalized medicine.AIM To identify predictors of long-term mucosal healing(MH) in patients with Crohn's disease(CD) treated with tumor necrosis factor α(TNF-α) inhibitors.METHODS Prospective single center study. Consecutive patients with clinically active CD requiring treatment with a TNF-α inhibitor were included. A baseline segmental CD Endoscopic Index of Severity(CDEIS) ≥ 10 in at least one segment or the presence of ulcerations were required for inclusion. Clinical, biological and endoscopic data were obtained at baseline, weeks 14 and 46. Endoscopic response(ER) was defined as a decrease ≥ 50% from baseline CDEIS and MH as partial CDEIS ≤ 5 in all segments.RESULTS Of 62 patients were included. At baseline, median CD Activity Index and CDEIS were 201 and 6.7, respectively with a significant reduction after one year of treatment(53 and 3.0 respectively, P < 0.001). At week 14, 56% of patients achieved ER and 34% MH. At week 46, the corresponding percentages were 52%and 44%. Baseline disease characteristics or biomarkers did not predict MH. A decrease from baseline CDEIS at week 14 of at least 80% was the best predictor of MH at week 46(59% sensitivity and 91% specificity; area under the curve =0.778).CONCLUSION Clinical and biomarker data are not useful predictors of response to TNF-αinhibitors in CD, whereas ER to induction therapy, defined as 80% reduction in global CDEIS, is a robust predictor of long-term MH. Achievement of this endoscopic endpoint may be considered as a therapeutic target for anti-TNF-αtherapy. | Ignacio Alfaro Maria Carme Masamunt Nuria Planell Alicia López-García Jesús Castro Marta Gallego Rebeca Barastegui Angel Giner Alejandro Vara Azucena Salas Elena Ricart Julián Panés Ingrid Ordás | 2019 | World Journal of Gastroenterology2019，25，14： | 0 |
