Liver transplantation is typically considered curative; however, a subset of patients develop antibody\u2010induced BSEP deficiency (AIBD), a rare post\u2010transplant complication driven by recipient IgG antibodies against graft BSEP. Patients often present with recurrent cholestasis and graft dysfunction. Therapeutic plasma exchange (TPE) is increasingly used to remove circulating antibodies, often alongside immunomodulatory therapies. We describe a patient with PFIC\u20102 who developed four distinct AIBD relapses over a 24\u2010year period, beginning 12\u2009years after transplantation. Each relapse was treated with a coordinated regimen including TPE, intravenous immunoglobulin (IVIg), rituximab, and optimized maintenance immunosuppression. TPE procedures were performed using the Spectra Optia system with one plasma volume exchange using citrate anticoagulation. Across all relapses, TPE was associated with rapid reductions in cholestatic markers, with the greatest improvements noted after apheresis initiation. TPE procedure intensity evolved over time, with earlier initiation and a gradual increase in the total number of exchanges per relapse. Biopsies demonstrated progressive cholestatic injury, yet graft function remained preserved and re\u2010transplantation was avoided. Adverse events were infrequent and managed conservatively. This case highlights the potential role of early and sustained use of TPE as part of a multimodal strategy for managing recurrent AIBD. Consistent clinical and biochemical improvement across relapses supports incorporating TPE with immunosuppression and B\u2010cell targeted therapy in similar presentations. Further studies are needed to clarify optimal timing, frequency, and treatment combinations.\n                  <\/jats:p>","DOI":"10.1002\/jca.70096","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T03:50:24Z","timestamp":1771818624000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long\u2010Term Management of Recurrent Antibody\u2010Induced Bile Salt Export Pump Deficiency After Liver Transplantation Using Therapeutic Plasma Exchange"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9670-1917","authenticated-orcid":false,"given":"David","family":"Daniel","sequence":"first","affiliation":[{"name":"Department of Pathology Johns Hopkins University School of Medicine  Baltimore Maryland USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Pathology Johns Hopkins University School of Medicine  Baltimore Maryland USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoko","family":"Oshima","sequence":"additional","affiliation":[{"name":"Department of Pathology Johns Hopkins University School of Medicine  Baltimore Maryland USA"},{"name":"University of Pittsburgh Medical Center  Pittsburgh Pennsylvania USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonja O.","family":"Vozniak","sequence":"additional","affiliation":[{"name":"Department of Pathology Johns Hopkins University School of Medicine  Baltimore Maryland USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0517-3766","authenticated-orcid":false,"given":"Aaron A.
