RESUMEN
Cytomegalovirus (CMV) is the most common viral pathogen that negatively affects the outcome of liver transplantation. CMV causes febrile illness often accompanied by bone marrow suppression, and in some cases it invades tissues, including the transplanted allograft. In addition, CMV has been significantly associated with an increased predisposition to allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survivals. We carried out a study on a Spanish adult liver transplant recipient who rapidly presented anemia and was diagnosed as having Coomb negative (nonimmune) hemolytic anemia, gastric ulcer, pneumonitis, and cholangitis associated with a CMV infection.
