Related Articles Is There a Role for Thiopurines in IBD? Am J Gastroenterol. 2018 Jun 27;: Authors: Cross RK, Herfarth H Abstract Immunosuppressive therapy (IM) is inexpensive and nearly one-third of patients with inflammatory bowel disease (IBD) experience a benefit from treatment. IM may be ideal for IBD patients at low risk for a disabling disease course or colectomy and/or those patients with inadequate access to biologic therapy. A majority of IBD patients benefit from early biologic therapy with improved short and likely long-term outcomes. Improved methods are needed to…
