Life-threatening bowel complications following anti-tumor necrosis factor antibody therapy for patients with inflammatory bowel disease: A report of three cases in Taiwan

Incidence of inflammatory bowel disease (IBD) in Taiwan and the experience of the management of serious complications is much lower than in Western countries. The authors just want to alert readers that anti-tumor necrosis factor (TNF) is not without life-threatening complications. Three serious complications were described, including surgical management and outcomes following the application of anti-TNF monoclonal antibody therapy for IBD. Case 1 involved a 25-year-old man treated with five doses of adalimumab for moderate control of Crohn's disease (CD). Six months later, he experienced severe intestinal obstruction, which necessitated right hemicolectomy with ileocolic anastomosis. He recovered postsurgery. Case 2 involved a 54-year-old man treated with adalimumab for intractable ulcerative colitis. Ten days after the second dose of adalimumab, an emergent subtotal colectomy with ileostomy was performed for a transverse colon perforation with peritonitis. The patient underwent an ileal pouch operation a year later. Case 3 was based on a 16-year-old male patient treated with six doses of an infliximab biosimilar for CD; thereafter, an emergent subtotal colectomy with ileostomy and Hartmann's pouch was performed for peritonitis with the presence of a perforated gastrocolic fistula tract. He had no serious complications following an uneventful recovery period. Creating awareness of serious complications associated with biologic treatments and offering appropriate patient management, including surgical treatment, is beneficial to patients.
