BACKGROUND: Bacillary peliosis hepatis is an uncommon but well recognized disease due to disseminated Bartonella infections occurring predominantly in immunocompromised individuals infected with human immunodeficiency virus, type 1. A similar condition in the absence of Bartonella infection when described in organ transplant patients was felt to be secondary to azathioprine and/or cyclosporine. METHODS: Herein, we report the first case of bacillary peliosis hepatis due to systemic Bartonella henselae infection in a patient after kidney transplant. The patient presented with severe anemia, persistent thrombocytopenia, and hepato-renal syndrome. DNA-based polymerase chain reactions (PCR), which allowed direct detection of both B henselae and quintana DNA in patient's peripheral blood and liver tissue, were used. Indirect immunofluorescence assay for Bartonella serology was performed on peripheral blood. RESULTS: Histopathology of the liver biopsy demonstrated peliosis hepatis. Indirect immunofluorescence assay for Bartonella serology was positive, and B henselae DNA was identified by PCR in the peripheral blood and liver tissue. Treatment with a 3-month course of oral erythromycin resulted in an excellent clinical response. CONCLUSIONS: The present case suggests that although various anti-rejection therapies and opportunistic infections are associated with hepatic and renal dysfunction along with bone marrow suppression, the diagnostic evaluation in this situation should include liver biopsy and a careful search for evidence of systemic Bartonella infection, e.g., exposure to cats, Bartonella serology, and Bartonella DNA by PCR. A reduction in immunosuppression and prolonged therapy with antibiotics such as erythromycin will often result in early recovery.
