Patient stratification according to the risk of developing complications is an essential step to define the best treatment approach in patients with ulcerative colitis (UC). Recently, Siegel et al (Gut 2017) published a score that aims to access the disease severity, considering disease activity (both clinical and endoscopic factors) and complications during the disease course, ranging from 0 to 100 values (higher values indicating worse disease severity). Our goal was to evaluate the capacity of this score calculated at the time of diagnosis (dx) to predict disease course during follow-up (FU): steroid use, therapy escalation to immunomodulators or biologics, hospitalisation and/or abdominal surgery.
Retrospective cohort study including incident cases of UC in our centre between December 2012 and December 2018. We calculated the score at the time of dx and at the end of FU and collected data about disease course.
Eighty-five patients (57% men with a mean age of 43 ± 17 years) with newly diagnosed UC were included. Disease extension according to Montreal was E1 in 30/85 patients, E2 in 37/85 patients and E3 in 18/85 patients. Median FU time was 40 months. Median risk score at the time of dx was 30 (IQR 3–91) and it was higher in patients with younger age (36 vs. 26,
This severity score seems to be a promising tool for risk stratification and prognosis determination in patients with UC, and its utility should be validated in prospective studies.
