Autopsy-determined causes of death in solid organ transplant recipients.
The aim of this study was to review the main causes of death as determined by autopsy of deceased solid organ transplant recipients. We reviewed 156 autopsies including 76 heart, 32 liver, 29 kidney, and 19 lung transplant recipients. The mean survival period varied depending on the transplanted organ: namely heart, 497 days; liver, 189 days; kidney, 1124 days; and lung, 252 days. Infections were the most common cause of death in all groups, varying from 21% in heart to 63% in lung recipients. Acute rejection, chronic rejection, and malignancies only appeared as the cause of death in heart recipients (14.5%, 9.2%, and 4%, respectively). Primary graft failure was present in heart (15.7%), kidney (3.4%), and lung (5.3%) recipients. The highest rate of surgical complications as a cause of death was observed in heart transplant recipients. In all groups there was a significant percentage (about 30%) of other pathologies that were responsible for death, such as pulmonary embolism, central nervous system pathology, acute pancreatitis, digestive hemorrhage, and acute myocardial infarction. Our results emphasize that infections are the main cause of death within the first year posttransplant, independent of the organ transplanted.
