Syphilis-related hepatitis in a liver transplant patient

We herein describe a case of secondary syphilis hepatitis in a liver transplant patient. This homosexual man presented 15 years after an orthotopic liver transplant with nonsquamous papillomacular rash, mild cytolysis, and anicteric cholestasis. Laboratory tests showed syphilis seroconversionwith a VDRL test titer of 1/256, a Treponema pallidum hemagglutination assay of 1/5120, and a positive immunoglobulin M fluorescent Treponemal antibody absorbance. A liver biopsy performed 13 months after the diagnosis showed low-grade hepatitis with a METAVIR score of A1F1; it also showed moderate, nonspecific portal inflammation consisting primarily of neutrophils, with no evidence of cholestasis. The patient was given benzathine-penicillin (2400000 IU) with a transient increase in prednisolone dosages. Cytolysis rapidly, and cholestasis progressively, disappeared. Results of an immunoglobulin M fluorescent Treponemal antibody absorbance test became negative, whereas the VDRL test and the Treponema pallidum hemagglutination assay titers decreased slightly over time.
