ABSTRACT
OBJECTIVE:
Infliximab is a first-line biologic agent for the treatment of Crohn's disease (CD), in which loss of response (LOR) remains a challenge in the treatment of patients with CD. The study aimed to explore the association between body composition parameters and LOR to infliximab in CD patients.METHODS:
118 patients with CD admitted to the First Affiliated Hospital of Wenzhou Medical University and treated with infliximab from June 2015 to December 2021 were retrospectively enrolled. The body composition of patients was analyzed by computed tomography (CT). The primary outcome measure was the one-year LOR. Patients were divided into the Remission group and the LOR group to analyze the association between body composition parameters and the LOR to infliximab.RESULTS:
The rate of sarcopenia in the LOR group was higher than in the Remission group (83.7% vs. 60.0%, P=0.008). Multivariate analysis showed that females had a lower risk of sarcopenia than males (OR=0.30, 95%CI 0.11-0.81, P =0.017); BMI was significantly associated with sarcopenia (OR=0.68, 95%CI 0.56-0.83, P <0.001); L1 CD and L2 CD had a lower risk of sarcopenia than L3 CD (OR=0.29, 95%CI 0.10-0.83, P =0.021; OR=0.25, 95%CI 0.07-0.87, P=0.028).CONCLUSIONS:
Sarcopenia was identified as a risk factor for developing LOR in infliximab-treated patients.
