title: Approach to a Child with Colitis.
abstract: In this review, the authors discuss the etiology, pathogenesis, and clinical presentations of colitis in children, and provide current recommendations for the approach to a child with colitis. In addition, they discuss in detail one of the important and emerging causes of chronic colitis in children; inflammatory bowel disease (IBD). Diagnostic and management approaches to colitis in children vary considerably based on several factors, including if the colitis is acute in onset or chronic, the age of the child, and the geographical region of the affected child. Broader classification or differential diagnosis of colitis falls under infectious, inflammatory, allergic, and less commonly, immune-mediated and ischemic colitis. Recent epidemiologic reports have elucidated a shift in our understanding of ethnicities and geographic regions affected by IBD. The incidence and prevalence of IBD has been steadily increasing in developing countries, including South-East Asia/India. Also, the risk of developing IBD among the second-generation South-Asians immigrants has greatly increased, with rates approaching those in the Western country to which they immigrated. Current research is focusing on genetic, environmental, and dietary factors to understand the increased incidence of IBD in developing countries and immigrants from developing nations.
