Acute central nervous system graft-versus-host-disease after liver transplantation.

Acute Central Nervous System (CNS) Graft Versus Host Disease (GvHD) is a rare form of GvHD, only described in case reports. Knowledge about this condition is extrapolated from chronic CNS GvHD cases occurring mostly after hematopoietic stem cell transplantation. GvHD following solid organ transplantation is an unexpected complication. GvHD after liver transplantation has a poor prognosis, and the optimal management is not yet known. Here we describe the case of a 63-year-old man who underwent deceased donor liver transplantation and subsequently developed skin rash, colitis and pancytopenia followed by refractory status epilepticus. Following the identification of lymphocytes of donor origin in the cerebrospinal fluid of the patient, he was diagnosed with acute CNS GvHD. He was treated with an intensive immunosuppressive regimen, but care was withdrawn due to lack of improvement and worsening neurologic prognosis. It is the second known case of acute CNS GvHD following liver transplantation. Clinicians should be aware of this possible, although rare, complication of liver transplantation, especially when there is refractory status epilepticus of unknown origin.
