Adenovirus-Related Fulminant Liver Failure After Kidney Transplantation

BACKGROUND Human adenovirus is a well-known pathogen that can potentially lead to severe infection in immunocompromised patients. Adenovirus infections in solid-organ transplant recipients can range from asymptomatic to severe, prolonged, disseminated disease, and have a significant impact on morbidity, mortality, and graft survival. The clinical manifestations vary from asymptomatic and flu-like illness to severe life-threatening viremia with multi-organ failure. Post-transplant adenovirus infection is well described in kidney recipients, but in adult liver transplant recipients the impact of the virus is not well described. In this report, a case of disseminated adenovirus infection with subsequent fatal acute liver failure in a post-kidney transplant patient is presented. CASE REPORT A 51-year-old man underwent a deceased kidney transplantation for focal segmental glomerulosclerosis. Shortly after the kidney transplantation, he received multiple plasmapheresis with additional steroid treatments for cellular rejection and reoccurrence of his primary kidney disease. Three weeks after the kidney transplant, he developed a disseminated adenovirus infection with subsequent acute liver failure. Despite the early diagnosis and aggressive treatment, the patient died. CONCLUSIONS Patients with organ transplantation with autoimmune background etiology are usually over-immunosuppressed to avoid early rejection. In this population, opportunistic infections are not rare. Fever, general malaise, and transplant organ dysfunction are the first signs of bacterial or viral infection. Early infectious diseases work-up, including tissue biopsy, is fundamental to establish a diagnosis. Broad antibiotic and possible antiviral aggressive treatment are mandatory.
