Abstract

Advancements in murine modeling systems for ulcerative colitis have diversified our understanding of the pathophysiological factors involved in disease onset and progression. This has fueled the identification of molecular targets, resulting in a rapidly expanding therapeutic armamentarium. Subsequently, management strategies have evolved from symptomatic resolution to well-defined objective endpoints, including clinical remission, endoscopic remission and mucosal healing. While the incorporation of these assessment modalities has permitted targeted intervention in the context of a natural disease history and the prevention of complications, studies have consistently depicted discrepancies associated with ascertaining disease status through clinical and endoscopic measures. Current recommendations lack consideration of histological healing. The simultaneous achievement of clinical, endoscopic, and histologic remission has not been fully investigated. This has laid the groundwork for a novel therapeutic outcome termed disease clearance (DC). This article summarizes the concept of DC and its current evidence.

Core Tip: Clinical management of ulcerative colitis is guided by a combination of clinical and endoscopic measures, but histologic healing is undervalued. The current definition of disease remission is insufficient due to discrepancies in outcomes. Disease clearance (DC) is a novel emerging composite outcome defined as the simultaneous attainment of clinical, endoscopic and histologic remission. The risk of disease relapse, hospitalization and surgery is significantly lower in patients who achieve DC. It provides superior optimal disease control in the short term. Large prospective studies are needed to determine the cost effectiveness, risk-benefit ratio and impact on long-term outcomes.
