Inflammatory Bowel Diseases and Kidney Transplantation: A Narrative Review of Clinical Management Approaches

Inflammatory bowel disease is not uncommon among kidney transplant recipients. In transplant patients with chronic diarrhea and abdominal pain, de novo inflammatory bowel disease can be considered among differential diagnoses, after exclusion of infectious causes and drug-induced diarrhea. Inflammatory bowel disease, in the cnnnontext of organ transplant, is associated with a higherrisk of morbidity, increased rate of hospitalization, and higher mortality.Therefore, a multidisciplinary approach, before and after transplant, among a gastroenterologist specialized in inflammatory bowel disease, a gastrointestinal surgeon, and a transplant clinician is essential, given the higher clinical complexity for this subgroup of patients. Limited data are available on management of inflammatory bowel disease in kidney transplant recipients, although the concurrent use of immunosuppressive therapy can mitigate flare-ups but with increased infection risks. Colorectal cancer can be a serious complication of inflammatory bowel disease; hence, patient compliance with regular colonoscopy surveillance programs is crucial. Patients with inflammatory bowel disease who are undergoing kidney transplant have a shorter overall survival rate compared with matched control groups. However, inferences based on studies involving inflammatory bowel disease in kidney transplant recipients are blighted by small sample sizes,thus making it difficult to draw accurate conclusions. Our review was undertaken to comprehensively report the clinical approaches to kidney transplant recipients with inflammatory bowel disease, describing their clinical course, outcomes, and management plan.
