Abstract:
Objective:To evaluate the efficacy and safety of ustekinumab (UST) for Crohn′s disease (CD) .Methods:A retrospective cohort study was conducted to collect clinical data of CD patients with active lesions in colonoscopy before the treatment of UST in Renji Hospital of Shanghai Jiaotong University School of Medicine from May 2020 to September 2021. Primary endpoint was the endoscopic response and remission rates at the 24th/32th week after the treatment of UST.Results:A total of 36 CD patients who were endoscopically active at baseline [25 men, 11 women; mean age, 29.8±8.7 years; disease duration, 38.0 (15.5, 66.1) months] were included. According to Montreal classification, 4 patients (11.1%) were L1 type (terminal ileum) , 4 (11.1%) were L2 type (colon) , 28 (77.8%) belonged to L3 type (ileocolon) , and upper digestive tract involvement occurred in 4 (11.1%) . As for disease behavior, 28 patients (77.8%) had non-structuring and non-penetrating lesions; 5 (13.9%) had structuring lesions and 3 (8.3%) had penetrating lesions. (1) Endoscopic activity: At the 24th/32th week, the endoscopic remission rate and response rate were 33.3% (12/36) and 63.9% (23/36) , respectively. There was no statistically significant difference in endoscopic remission rate and response rate between first-line and second-line usages of UST (all P>0.05) . (2) Clinical activity: Among the 36 patients, 16 were in the clinical active phase, and 20 patients were in the clinical remission phase at baseline. The clinical remission rate and clinical response rate of 16 clinical active patients at the 24th/32th week were 81.2% and 93.8% respectively. (3) Radiological activity: Twenty-seven patients completed the radiological evaluation at the 24th/32th week. In 3 patients with L1 lesions, 2 achieved response or partial response and no response in 1. In 24 patients with L3 lesions, radiological response occurred in 5 patients (20.8%) , partial response in 19 (79.2%) , and no response in 5 (20.8%) . In 19 patients with active perianal fistula at baseline, 6 achieved healing fistule at the 24th/32th week, 2 had partial response, 6 remained stable, while progress were seen in the other 5. (4) Serological and nutritive index: Compared with baseline values, the body mass index, hemoglobin and serum albumin levels of patients were significantly improved at the 24th/32th week (all P<0.05) , but the level of C-reactive protein and erythrocyte sedimentation rate at the 24th/32th week showed no significant difference (all P>0.05) . (5) Safety: No serious adverse events and infusion reactions were observed, and adverse events occurred in 2 patients. Conclusion:UST can effectively improve the endoscopic manifestations, clinical symptoms, imaging and nutritive index of CD patients with good safety.
