ECCO Guidelines on Therapeutics in Crohn's Disease: Medical Treatment

Abstract

Crohn’s disease [CD] is a chronic inflammatory bowel disease [IBD] that can result in progressive bowel damage and disability1. CD can affect individuals of any age, from children to the elderly, 2, 3 and may cause significant morbidity and impact on quality of life. Up to one-third of patients present with complicated behaviour [strictures, fistula, or abscesses] at diagnosis4. Most patients over time will develop a complication, with roughly 50% of patients requiring surgery within 10 years of diagnosis5-7. As the precise aetiology of CD remains unknown, a curative therapy is not yet available8. Several agents are available for the medical treatment of CD. Medical agents include mesalazine [5-ASA], locally active steroids [such as budesonide], systemic steroids, thiopurines such as azathioprine [AZA] and mercaptopurine [MP], methotrexate [MTX], and biological therapies [such as anti-TNF, anti-integrins, and anti-IL12/23]. \nThe European Crohn’s and Colitis Organisation [ECCO] produces and regularly updates several guidelines aimed at providing evidence-based guidance on critical aspects of IBD care to all healthcare professionals who manage patients with IBD. To provide high-quality evidence-based recommendations on medical and surgical treatment in CD, ECCO decided to develop these guidelines by adopting the GRADE [Grading of Recommendations Assessment, Development, and Evaluation] approach9. GRADE is a systematic process for developing guidelines that addresses how to frame the healthcare questions, summarize the evidence, ..
