There is a lack of standardized guidance, and treatment approaches vary across institutions. A writing group from the Society of Pediatric Liver Transplantation conducted a comprehensive review of the published literature and collected institutional guidance documents from pediatric transplant centers across the United States to synthesize current diagnostic and management approaches to AMR in pediatric liver transplant recipients. AMR is diagnosed by the presence of characteristic histologic injury, C4d deposition, circulating donor\u2010specific antibody (DSA), and exclusion of alternative causes of graft dysfunction, including T cell\u2013mediated rejection. Management strategies focus on reducing circulating DSA through therapeutic plasma exchange and suppressing ongoing immune activation with corticosteroids and intravenous immunoglobulin. In severe or refractory cases, targeted therapies such as rituximab, bortezomib, and eculizumab may be considered. A stepwise diagnostic and management algorithm is presented. This resource outlines a practical approach to the diagnosis and management of AMR in pediatric liver transplantation, serving as a reference for busy clinicians who may encounter this serious but underrecognized cause of graft dysfunction and loss.<\/jats:p>","DOI":"10.1111\/petr.70455","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T12:04:46Z","timestamp":1788869086000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An Approach to Antibody\u2010Mediated Rejection in Pediatric Liver Transplantation"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0437-6569","authenticated-orcid":false,"given":"Catalina","family":"Jaramillo","sequence":"first","affiliation":[{"name":"Division of Pediatric Gastroenterology, Hepatology, and Nutrition, Primary Children's Hospital University of Utah School of Medicine  Salt Lake City Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7523-3437","authenticated-orcid":false,"given":"Parmjeet","family":"Randhawa","sequence":"additional","affiliation":[{"name":"Division of Transplantation Pathology, The Thomas E Starzl Transplantation Institute University of Pittsburgh School of Medicine  Pittsburgh Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4749-9737","authenticated-orcid":false,"given":"Amrita","family":"Narang","sequence":"additional","affiliation":[{"name":"Section of Transplant Hepatology, Division of Pediatric Gastroenterology, Hepatology, and Nutrition Stanford University School of Medicine  Palo Alto California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6766-7166","authenticated-orcid":false,"given":"Alison J.","family":"Gareau","sequence":"additional","affiliation":[{"name":"Department of Surgery University of Wisconsin\u2010Madison School of Medicine and Public Health  Madison Wisconsin USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0237-560X","authenticated-orcid":false,"given":"Jody","family":"Weckwerth","sequence":"additional","affiliation":[{"name":"Division of Pediatric Gastroenterology and Hepatology Mayo Clinic Transplant Center, Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6258-4492","authenticated-orcid":false,"given":"Alisha","family":"Mavis","sequence":"additional","affiliation":[{"name":"Atrium Health  Charlotte North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2624-8632","authenticated-orcid":false,"given":"George","family":"Mazariegos","sequence":"additional","affiliation":[{"name":"Department of Surgery and Critical Care Medicine, Thomas E.
