    Abstract:
    OBJECTIVE: To compare the induction of remission and cost-effectiveness of enteral nutrition (EN) and infliximab (IFX) in moderate-to-severe active Crohn's disease(CD). METHODS: Moderate-to-severe active CD patients were divided into IFX group and EN group. Remission rate, time to remission and treatment cost were compared between the two groups. Clinical remission was defined as Crohn's disease activity index (CDAI) < 150. The quality of life was evaluated by inflammatory bowel disease questionnaire of quality of life (IBDQ). RESULTS: A total of 100 patients were analyzed, including 48 patients in IFX group and 52 patients in EN group. IFX group had higher remission rate [87.5% (42/48) vs 67.3% (35/52) , P = 0.017] and shorter time to remission [(11.00 ± 8.35) days vs (33.94 ± 14.60) days, P < 0.001] than EN group. Treatment costs before remission were similar in two groups (P = 0.351) . The increase of IBDQ scores before and after treatment in IFX group was much higher than that of EN group (42.74 ± 27.50 vs 7.57 ± 22.77, P < 0.001) . Similarly, patients in EN group had greater increase of body mass index (BMI) than that of IFX group [(1.32 ± 0.29)kg/m(2) vs (0.51 ± 0.07) kg/m(2), P < 0.001]. For patients with CDAI < 280, remission rate was not significantly different [85.7% (24/28) vs 81.8% (18/22) , P = 0.718] between the two groups, while treatment cost in EN group was less than that of IFX group [(16.1 ± 5.9)×10(3) RMB vs (22.9 ± 11.9)×10(3) RMB, P = 0.021]. CONCLUSIONS: For patients with severe CD (CDAI ≥ 280), IFX has higher remission rate, shorter time to remission and comparable treatment cost than EN. But for patients with CDAI < 280, EN group has comparable remission rate to IFX group with lower cost.
