In these guidelines, 5-ASA is the first-line therapy but not the last step if treatment goals are not met. At that time, the CAG guidelines acknowledged emerging evidence of a potential advantage for achieving endoscopic remission, but indicated that more evidence was needed to validate that goal.īy the time the STRIDE-II recommendations were issued in 2021, 8 a treat-to-target approach was advocated with endoscopic remission as the goal based on studies showing better outcomes when this more rigorous definition of remission is achieved. For the CAG, which last issued UC guidelines in 2015, no precise definition was provided for a treatment goal, but the inability to maintain corticosteroid-free remission was identified as a definition of treatment failure. The shared treatment goal is disease remission, but the definition of remission varies, ranging from absence of clinical symptoms to endoscopic healing. Other major guidelines, including those issued by the Canadian Association of Gastroenterology (CAG), 6 the American College of Gastroenterology (ACG), 3 the British Society of Gastroenterology (BSG), 7 and the International Organization for the Study of IBD (IOIBD), 8 also identify 5-ASA as the first-line treatment for mild-to-moderate UC. 4,5 Unlike moderate-to-severe UC, for which steroids and biologics are used early, 5-ASA remains the mainstay of mild-to-moderate UC management. In the case of the American Gastroenterological Association (AGA), guidelines have been issued separately for mild-to-moderate and moderate-to-severe UC. 3 In recognizing the substantial differences in the course and treatment of mild-to-moderate relative to moderate-to-severe UC, these strata of severity are typically treated differently. UC severity is defined by such factors as number of bowel movements per day, bleeding, endoscopic appearance, and the presence of elevated inflammatory markers, such as C-reactive protein (CRP). John Marshall on the impact to clinical practice, click here 2 Their symptoms overlap, but rectal bleeding is generally more common with UC.įor an exclusive interview with Dr. Both UC and Crohn’s disease are chronic inflammatory diseases of the gastrointestinal tract, but UC is limited to the colon and rectum and is contiguous, whereas Crohn’s can occur throughout the digestive tract with intermittent inflammation between areas of healthy tissue. 1 Of the nearly 300,000 cases of IBD, UC represents slightly less than half or about 45%. In 2018, the estimated prevalence of inflammatory bowel disease (IBD) in Canada was 0.7%, a rate that represents a substantial rise over the past several decades and that is now among the highest in the world. To optimize adherence, 5-ASA formulations with simple dosing schemes and effective delivery into the colon should be considered for their practical advantages. In addition, the mechanisms by which drugs are delivered to the inflamed tissue in the colon differ. However, the number of pills required per day is not the same. There are no studies to indicate that 5-ASA products differ in efficacy. Even if steroids or therapies can restore control, repeated cycles of disease activity can drive progression. In periods of UC quiescence, adherence to daily oral therapies such as 5-ASA commonly declines, allowing disease reactivation. To achieve and then maintain this goal, the challenge is strict adherence. In patients with mild-to-moderate ulcerative colitis (UC), 5-aminosalicylic acid (5-ASA) is an effective first-line option for the goal of clinical and endoscopic remission.
