Sequential transplantation and implications for clinical management: OLT followed by HCT and consequent RT in a pediatric patient

We report a case of a pediatric patient who required three separate transplants: OLT at the age 5, HCT at age 13 (8 years post‐OLT), and cadaveric RT at age 15 (10 years post‐OLT). The child initially presented with fulminant liver failure without known cause, ultimately undergoing OLT from his mother. He then developed SAA, for which he required HCT. Unfortunately, he developed ESRD secondary to prolonged CNI exposure, for which he underwent cadaveric RT. These processes then resulted in 7 years largely free from complications, during which a multi‐disciplinary team monitored the patient for complications. Regrettably, at the age of 21 he developed poorly differentiated mucinous adenocarcinoma of the colon which ultimately led to his demise. While there are case reports of patients requiring two sequential transplants, there is a paucity of reports of successfully completing three separate organ transplants in the same patient. Our case demonstrates progression of a pediatric patient through OLT, HCT, and RT with discussion of notable clinical implications. Secondarily, this case highlights the importance of coordination of care amongst various subspecialties to facilitate tandem transplantations and manage the complications of these processes. As pediatric patients have improved survival rates and may require multiple transplants, it remains important to highlight the feasibility as well as the complications of the tandem transplant process.
