Curcumin in Pediatric Ulcerative Colitis

Clinical efficacy of induction and maintenance medications in pediatric UC is limited with a cumulative long-term risk of 20%-30% for colectomy. Remission rates following induction with corticosteroids and 5-amino-salicylic acid (5-ASA) range from 20% to 50%. 5-ASA is still regarded as first line induction and maintenance therapy for mild to moderate UC in both children and adults. 5-ASA is also indicated for maintenance therapy following successful induction with corticosteroids for moderate to severe disease. Still, steroid free clinical remission at 1 year under 5-ASA maintenance therapy is reported to range from 40% to 50%. Management of recurrent flares while taking 5-ASA medications involves repeated courses of corticosteroids and changing therapeutic regimes to include more potent medications such as thiopurines which carry an increased risk for significant adverse effects. Hence, improving efficacy of induction and maintenance treatment is of critical importance. Curcumin, an active phytochemical substance with anti-inflammatory properties was studied extensively in-vitro and in experimental models of colitis. In the only randomized controlled trial, performed in adults with quiescent disease, curcumin was shown to be an effective concomitant treatment (along with 5-ASA) for maintenance of remission. Therefore, our aim is to assess the efficacy of concomitant curcumin maintenance therapy for induction and maintenance therapy in pediatric UC patients with mild to moderate in a prospective randomized, placebo controlled trial. We hope that this study will further contribute to the understanding of the potential benefits of curcumin in pediatric UC patients.
