Abstract:
Background:With the extensive use of infliximab (IFX)in treatment of patients with Crohn's disease (CD),some of the patients had losing of response to IFX treatment. The specific mechanism is not clear yet,and may be related to the formation of antibodies to infliximab (ATI). However,there is no report on the positivity rate of ATI in China so far. Aims:To investigate the clinical effects of serum IFX trough levels (IFX-TLs)and ATI in CD patients treated with IFX. Methods:A total of 76 CD patients receiving IFX treatment from Jan. 2016 to Mar. 2017 at Shanghai Renji Hospital were enrolled. Serum IFX-TLs and ATI were detected. CD patients were divided into active stage group and remission group according to CDAI score,and serum IFX-TLs,ATI,C-reactive protein (CRP)and erythrocyte sedimentation rate (ESR) levels were analyzed. Results:Of the 76 patients with CD,positive ATI was found in 2 patients (2. 6%). Forty-five (59. 2%)patients were in remission,while 31 (40. 8%)in active stage. No significant differences in IFX-TLs [2. 84 (1. 30,4. 96)μg/ mL vs. 4. 08 (1. 29,6. 72)μg/ mL,P =0. 484],ATI [8. 00 (5. 27,14. 89)ng/ mL vs. 7. 00 (4. 40, 25. 00)ng/ mL,P = 0. 454]were found between active CD and remission CD. Serum CRP,ESR levels were significantly increased in active CD than in remission CD (P = 0. 038,P = 0. 009). Logistic regression analysis showed that activity of CD was related to CRP (OR = 6. 082,95% CI:1. 348-27. 436,P = 0. 019),but not related to IFX-TLs,ATI and ESR (P > 0. 05). Conclusions:The activity of CD may be correlated with CRP,but not with IFX-TLs,ATI and ESR.
