Safety of vedolizumab in liver transplant recipients: A systematic review. Issue 7 (August 2019) - Spadaccini, Marco
Background: The management of inflammatory bowel disease in patients who have previously undergone liver transplantation can be a clinical challenge. There are serious concerns among physicians regarding the use of biologics for treating such immuno-compromised patients. Objective: We performed a systematic review on vedolizumab therapy in transplant recipients to assess its safety. Methods: PubMed/Embase/Scopus were searched up to November 2018 to identify papers regarding liver transplant recipients and therapy with vedolizumab. Primary outcomes were adverse events. Secondary outcomes were liver transplant and inflammatory bowel disease outcomes. Results: Eight studies (31 patients) were included. Nine out of 31 patients experienced an infection within a mean follow-up time ranging from 5–20 months. No malignancies were reported. Inflammatory bowel disease clinical response was experienced by 20/26 patients. Abnormalities in liver tests were recorded in 2/22 patients. Conclusion: Vedolizumab may be considered safe for treating inflammatory bowel disease in liver transplant recipients. Caution is recommended for patients with an unstable liver graft function.
