Abstract
Background and Aims
Intestinal ultrasound (IUS) is a useful modality to monitor patients with inflammatory bowel diseases (IBD). Little is known about the use of IUS and appropriate definitions for transmural response (TR) and healing (TH). We aimed to establish the use of IUS in monitoring TH as a potential target in routine medical practice.
Methods
Based on the prospective, non-interventional, multicentre studies TRUST and TRUST&UC, we conducted a post-hoc analysis of 351 IBD patients with increased bowel wall thickness (BWT). We analysed the rates of patients achieving TR and TH, comparing three definitions of TH. In 137 Crohn’s disease (CD) patients, the predictive value of TR and TH was investigated for the clinical and sonographic outcome at week 52.
Results
Within 12 weeks of treatment intensification, 65.6% (n = 118) of CD patients and 76.6% (n = 131) of ulcerative colitis (UC) patients showed a TR. Depending on the definition, 23.9%–37.2% (n=58/67/43) of CD patients and 45.0%–61.4% (n=90/105/77) of UC patients had TH at week 12. CD patients with TH were more likely to reach clinical remission at week 12 (OR 3.33 [1.09–10.2]; p = 0.044) and a favourable sonographic outcome (OR 5.59 [1.97–15.8]; p = 0.001) at week 52 compared with patients without TH.
Conclusions
IUS response and TH in a relevant proportion of patients suggests that IUS is a useful method to assess transmural inflammatory activity in daily clinical practice. TR and TH are predictive for the sonographic outcome at week 52.
