Twelve patients developed herpes simplex (HSV) hepatitis a median of 18 days after solid organ transplantation. This is earlier than cytomegalovirus hepatitis, which usually occurs 30-40 days after transplantation. Eight recipients (67%) died, and in seven, the diagnosis was made at autopsy or <48 h before death. Clinical manifestations associated with mortality were hypotension, disseminated intravascular coagulation (DIC), metabolic acidosis, gastrointestinal bleeding, and bacteremia. Laboratory abnormalities at diagnosis associated with mortality were high creatinine, low platelet counts, prolonged partial thromboplastin time, and a high percentage of band forms on the blood smear. Disseminated HSV disease was noted in four of six patients who had an autopsy and included involvement of lungs in three and the gastrointestinal tract in three. Five recipients developed DIC and all died. Pathologically, HSV hepatitis has two forms, focal and diffuse. All three patients with diffuse liver pathology died. However, three of seven with focal liver pathology survived with antiviral therapy, which suggests that early diagnosis and treatment may be lifesaving. None of these patients had received prophylactic acyclovir. It is possible that acyclovir prophylaxis may be able to prevent this disease.Herpes simplex virus (HSV) hepatitis is considered rare [1]. It has been observed most frequently as part of disseminated HSV in immunologically compromised patients or during pregnancy. Sporadic cases have been reported from this institution in renal transplant recipients and have ended fatally [2,3], as have most cases reported in the literature. Here we report 12 cases that occurred after solid organ transplantation over a 9-year period (1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988). This series is large enough to allow us to determine the approximate frequency of HSV hepatitis in our transplantation population; to present the effect of viral dissemination, the nature of the liver pathology, and the range of clinical and laboratory characteristics of the disease; and to investigate prognostic factors. Materials and Methods DefinitionsCases of HSV hepatitis were diagnosed by laboratory, histologic, and clinical findings of one or more of the following in liver tissue from a biopsy or autopsy: isolation of HSV, positive immunoperoxidase staining for HSV antigen, or histology showing intranuclear inclusion bodies and pathology consistent with HSV lesions. In one case there was no liver tissue to examine, and the diagnosis was made by isolation of HSV from multiple sites outside the liver, including buffy coat, and clinical evidence of fulminant hepatitis. The histologic pattern of Laboratory methodsTissue specimens obtained by biopsy or at autopsy were examined after routine staining and processing for detection of HSV antigen by immunoperoxidase staining and, on occasion, processed for isolation of HSV. Other specimens obtained from transplant recipients for viral isolation included throat wash, urine, buffy co...
The authors studied an 18-year-old woman with stage IIIB nodular sclerosis Hodgkin's disease whose bone marrow contained abnormal storage cells that resembled Gaucher cells by light microscopic examination ("pseudo-Gaucher" cells). Electron microscopic examination revealed that these cells differed from true Gaucher cells and resembled storage cells previously described in chronic myelogenous leukemia. The patient's peripheral blood leukocyte beta-glucosidase and serum acid phosphatase levels were elevated, ruling out the diagnosis of inherited Gaucher's disease. After treatment with six monthly cycles of systemic chemotherapy (nitrogen mustard, vincristine, procarbazine, bleomycin, doxorubicin, and prednisone), all signs of Hodgkin's disease and pseudo-Gaucher cells disappeared. Repeat leukocyte beta-glucosidase and serum acid phosphatase levels were unchanged. The present case is unique with its documentation of classical enzyme patterns for beta-glucosidase and acid phosphatase and electron microscopic features. The authors postulate that pseudo-Gaucher cells result from excessive cell breakdown with an overload of available beta-glucosidase.
