ABSTRACT Vanishing bile duct syndrome (VBDS) is a group of rare disorders characterized by ductopenia, the progressive destruction and disappearance of intrahepatic bile ducts leading to cholestasis. Described in association with medications, autoimmune disorders, cancer, transplantation, and infections, the specific mechanisms of disease are not known. To date, only 4 cases of VBDS have been reported in human immunodeficiency virus (HIV) infected patients. We report 2 additional cases of HIV-associated VBDS and review the features common to the HIV-associated cases. Presentation includes hyperbilirubinemia, normal liver imaging, and negative viral and autoimmune hepatitis studies. In HIV-infected subjects, VBDS occurred at a range of CD4+ T-cell counts, in some cases following initiation or change in antiretroviral therapy. Lymphoma was associated with two cases; nevirapine, antibiotics, and viral co-infection were suggested as etiologies in the other cases. In HIV-positive patients with progressive cholestasis, early identification of VBDS and referral for transplantation may improve outcomes.

    ABSTRACT: We report the case of a 10 year-old girl who had Stevens-Johnson syndrome and cholestasis after ibuprofen therapy. Liver histology was compatible with vanishing bile duct syndrome. She received ursodeoxycholic acid, and liver tests normalized within 7 months. This report confirms that ibuprofen may induce acute vanishing bile duct syndrome.

    ABSTRACT: A syndrome of idiopathic intrahepatic cholestasis occurs in some patients with Hodgkin's lymphoma. The underlying mechanism is poorly understood. In this paper we describe three patients with Hodgkin's lymphoma in whom severe intrahepatic cholestasis of unknown pathogenesis developed. In two cases jaundice was the presenting symptom; all three patients died with intractable liver damage. The three patients were initially thought to have idiopathic Hodgkin's-associated cholestasis, but subsequent review of histological material revealed advanced vanishing bile duct syndrome in addition to severe cholestasis. Ten liver specimens were obtained from 4 to 97 wk after the onset of jaundice (seven needle biopsies, one wedge biopsy, two postmortem livers). In seven liver specimens taken within 30 wk of the onset of jaundice, portal tracts characteristically had a "burned-out" appearance without secondary periportal changes related to chronic cholestasis. Three biopsy specimens obtained from one of the patients more than 1 yr after the onset of jaundice showed evidence of progressive periportal damage in the form of fibrous expansion, marginal ductular proliferation and copper-associated protein deposition. More than 80% of small portal tracts lacked recognizable bile ducts in the final liver specimens obtained from the three patients. These observations suggest that Hodgkin's lymphoma should be included in the list of diseases associated with loss of intrahepatic bile ducts. The possibility of a vanishing bile duct syndrome should be considered in the differential diagnosis of unexplained intrahepatic cholestasis in patients with Hodgkin's disease.

    ABSTRACT: It has been suggested that cytomegalovirus (CMV) infection is involved in allograft rejection. In liver transplantation, it has been suggested that CMV is associated with the development of vanishing bile duct syndrome (VBDS), and persistent CMV has been found in liver grafts that develop chronic rejection. In this experimental study, the effect of rat CMV (RCMV) infection on intragraft changes was investigated in a rat model of acute liver allograft rejection. Liver transplantations were performed in a rat strain combination of PVG (RT1c) --> BN (RT1n). No immunosuppression was given. One group of animals was infected with RCMV Maastricht Strain (10(5) plaque-forming units, intraperitoneally), and another group was left uninfected. The grafts were examined histologically after the rats were killed on postoperative days 7 through 9 at the early phase and days 20 through 30 at the late phase of rejection. Immunohistochemical studies were performed to demonstrate the immunological activation markers major histocompatibility complex class II and interleukin 2 receptors, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), and their ligands. RCMV infection was demonstrated from the grafts by culture and direct antigen detection. In liver allografts undergoing acute rejection, CMV significantly increased portal inflammation and caused more severe bile duct damage than in the uninfected grafts. CMV was also linked to the induction of VCAM-1 in the endothelial cells. The ongoing infection was found to vary over time in the different structures of the liver grafts, including the vascular endothelium and bile ducts. Our results support an association between CMV infection and the immunological mechanisms of rejection, as well as the role of CMV in the development of bile duct damage in liver allografts.
