Adenovirus infection in adult orthotopic liver transplant recipients: incidence and clinical significance.

Adenovirus infection occurs in 10% of pediatric orthotopic liver transplant recipients; however, no cases have been described in adult liver transplant recipients. A retrospective review of 191 adults who underwent liver transplantation from January 1988 through October 1995 was done to describe the incidence and clinical significance of adenovirus infection in this population. There were 11 (5.8%) patients with 16 cultures positive for adenovirus. Sites of isolation were urine (9), blood (2), liver biopsy (2), colonic biopsy (1), lung biopsy (1), and stool (1). Adenovirus infection was classified as either disease or asymptomatic infection. There were 7 cases of adenovirus disease (2 definite, 1 probable, and 4 possible). Disease was disseminated in 3 patients: All had pneumonia and 2 died. Of the 3 patients with pneumonia, 2 had evidence of multiorgan involvement. Adenovirus disease occurs in adult orthotopic liver transplant recipients and may be associated with significant morbidity and occasional mortality.
