“…ASC is the extreme end of the spectrum of disease severity in UC and occurs when this inflammation spills beyond the intestine and manifests in the form of elevated ESR, fever, tachycardia, and anemia, and these features form the part of Truelove and Witt's criteria 11 for diagnosis of ASC. In this severe subgroup of UC as well, the extent of severity can predict short-term outcomes as shown in the landmark paper, which led to the development of Oxford criteria, 16 and by us in a recent study, 17 in which fecal calprotectin could predict short-term outcomes in ASC. Regarding long-term outcomes in ASC, the only factor that is consistent across all studies is the response to intravenous steroids at day 7, 2,3 and this in turn depends on the severity of ASC at index admission.…”
