11/835. HBsAg carrier with simultaneous amebic liver abscess and acute hepatitis E.

    hepatitis e virus (HEV) infection and amebiasis are waterborne diseases that are endemic in india. However, their co-occurrence has never been described. We report a patient who presented with fever, jaundice and tender hepatomegaly and on investigation was found to have coexisting acute hepatitis E and amebic liver abscess. Incidentally, he was also an HBsAg carrier.

12/835. Weils' syndrome and concomitant hepatitis B infection.

    leptospirosis is a ubiquitous, spirochetal zoonosis which presents with a broad clinical spectrum. Weil's syndrome, characterised by jaundice, renal failure and bleeding manifestations is the most severe form. A high index of suspicion for the diagnosis is required to institute therapy promptly. We describe a case of serologically confirmed Weil's syndrome with concomitant hepatitis B infection.

13/835. Quantitative dna analysis of low-level hepatitis B viremia in two patients with serologically negative chronic hepatitis B.

    Low-level viremia due to hepatitis b virus (HBV) was demonstrated in the sera of two patients diagnosed previously as having non-B, non-C chronic hepatitis. Both patients had a "silent" HBV infection, because they were negative for both hepatitis B surface antigen (HBsAg) and anti-hepatitis B core antibody. The TaqMan chemistry polymerase chain reaction (PCR) amplified the HBV dna, enabling quantitation of the virus in their sera. Their serum HBV dna concentrations were low: the amount of each HBV S or X gene amplified showed there were approximately 10(3) copies/ml and HBV dna was detected occasionally during clinical follow-up. Positive HBsAg staining in liver tissues was demonstrated by an immunoperoxidase technique. Vertical transmission of silent HBV from one patient to her daughter was confirmed. Direct nucleotide sequencing of the amplified HBV X region revealed several mutations, suggesting reduced viral replication. One patient had a T-to-C mutation at the extreme 5'-terminus of the direct repeat 2 region and the other exhibited a coexisting X region with a 155-nucleotide deletion. These findings suggest that HBV replication is suppressed considerably in patients with silent hepatitis B.

14/835. association of lamivudine resistance in recurrent hepatitis B after liver transplantation with advanced hepatic fibrosis.

    BACKGROUND: Orthotopic liver transplantation (OLT) in patients with hepatitis b virus (HBV) infection is known to be associated with a high recurrence rate and poor prognosis. lamivudine, a nucleoside analogue, is a potent inhibitor of HBV replication, but it is associated with a 14-39% rate of resistance. methods: We report on four patients who underwent OLT for HBV infection. In all cases, the HBV infection recurred in the grafted liver and was treated with lamivudine (100 mg daily) on a compassionate-use basis. The patients were monitored closely for serum liver enzymes, hepatitis B surface antigen and HBV dna (by hybridization). Liver biopsy was performed before and after lamivudine therapy. HBV dna was amplified from serum for each patient and sequenced through a conserved polymerase domain, the tyrosine-methionine-aspartate-aspartate (YMDD) locus. RESULTS: All four patients exhibited lamivudine resistance 9-20 months after initiation of the drug. In all patients with a clinically mild disease, liver histology findings (12-24 months after lamivudine therapy) showed progressive fibrosis as compared to biopsies performed before lamivudine therapy, with a significant increase (> or =2 points) in the Knodell score in three patients. Moreover, two patients exhibited worsening of the necroinflammatory process. A mutation at the YMDD motif of the HBV polymerase gene was detected in all cases. CONCLUSIONS: lamivudine resistance frequently occurs in patients with recurrent HBV infection after OLT and is associated with advanced hepatic fibrosis and necroinflammatory process. A combination of antiviral therapies may be necessary.

15/835. hematopoietic stem cell transplantation from non-replicative hepatitis b virus carriers is safe.

    BACKGROUND/AIMS: hepatitis b virus can cause serious problems in individuals undergoing organ transplantation. The aim of this study was to evaluate the hepatic events among HBs-Ag positive recipients and HBs-Ag negative recipients who received products from hepatitis b virus carriers. methods: A total of 151 patients received an allogeneic hematopoietic stem cell transplantation at the Department of hematology-Oncology, University of Ankara, between June 1989 and June 1998. Among these, eight HBs-Ag positive and four HBs-Ag negative recipients received a product from a hepatitis b virus positive donor. The median follow-up period for these 12 patients was 13.2 months. RESULTS: Three of the eight HBs-Ag positive recipients died (one from hepatic failure); of the remainder, two are HBs-Ag negative, two HBs-Ag positive with normal liver injury tests and one HBs-Ag positive with elevated ALT levels. Of the four HBs-Ag negative recipients who received stem cells from a hepatitis B positive donor, two died; none of the patients in this group became HBs-Ag positive after transplantation. CONCLUSION: hepatitis b virus infection is a common problem in patients being considered for allogeneic hematopoetic stem cell transplantation, especially in areas where hepatitis b virus infection is endemic. We believe that the presence of HBs-Ag positivity is not an absolute contraindication for allogeneic hematopoetic stem cell transplantation unless the hepatitis b virus is in a replication phase.

16/835. Clearance of HCV rna in a chronic hepatitis c virus-infected patient during acute hepatitis b virus superinfection.

    The routes of hepatitis b virus and hepatitis c virus transmission are quite similar and coexistence of both viruses in one patient is not a rare phenomenon. Until now, the natural course of liver diseases induced by coinfections has not been well documented and the mechanisms of interaction between the two viruses and the human host have not been fully clarified. We report the case of a patient suffering from chronic hepatitis due to hepatitis c virus who developed an acute hepatitis b virus superinfection. serum hepatitis c virus ribonucleic acid became undetectable by reverse transcriptase/polymerase chain reaction at diagnosis of acute hepatitis b virus infection. At the same time, there was a striking increase in the serum concentrations of the antibodies against C22 and C33c hepatitis c virus antigens. Four months after clinical resolution of the acute hepatitis, hepatitis B surface antigen was undetectable in serum and three months later antibodies against hepatitis B surface antigen appeared. Two years after acute hepatitis b virus infection, the patient has had no relapse of markers for viral replication of hepatitis b virus. transaminases are within the reference range and hepatitis c virus ribonucleic acid is undetectable in both serum and liver tissue. We hypothesize that acute hepatitis b virus infection stimulated a specific humoral response against hepatitis c virus as well as triggering non-specific defense mechanisms which finally eliminated both viruses.

17/835. Successful recanalization of late portal vein thrombosis after liver transplantation using systemic low-dose recombinant tissue plasminogen activator.

    portal vein thrombosis (PVT) is an infrequent complication following hepatic transplantation. However, deterioration of liver function and accompanying complications may be life threatening. Several attempts of surgical or percutaneous transhepatic procedures have been described. In some cases high dose fibrinolytic regimens have been successful. We describe the case of a male liver recipient with recurrent liver fibrosis due to hepatitis B reinfection and late portal vein thrombosis 45 months after transplantation. Complete recanalization was achieved using systemic low dose recombinant tissue plasminogen activator (rt-PA).

18/835. Nosocomial transmission of hepatitis b virus infection through multiple-dose vials.

    The source of acute hepatitis b virus (HBV) infection in two women (55 and 72 years old) was investigated. They displayed no risk factors for acquiring HBV infection, other than treatment with local anaesthetic injections some months previously. The HBV strains were sequenced and showed distinct homology to strains seen in Swedish intravenous drug users (IVDU). Prior to these patients' acute infection, an outbreak of HBV had occurred among IVDU in the same county. Analysis of the HBV strains from six of these IVDUs showed their core promoter, precore and pre-S sequences (679 nucleotides) to be identical to those from the two patients. Cross-contamination between samples was excluded and the most likely source of infection was thought to be multiple-dose vials of local anaesthetic that had been contaminated with the HBV strain circulating among the IVDU population in the community. We believe that multiple-dose vials have no place in modern healthcare and recommend sequence homology analysis as an alternative or additional way to trace a source of HBV infection.

19/835. Reversible bilateral hydronephrosis without obstruction in hepatitis B-associated polyarteritis nodosa.

    The manifestations of polyarteritis nodosa (PAN) are varied, but urological abnormalities other than ureteric stenosis and orchitis have not been described. We report a case of hepatitis B-associated PAN with bilateral hydronephrosis without obstruction. Retrograde urography conclusively demonstrated the absence of obstruction. vasculitis-related myopathy, or neuropathy of the ureter, is the most likely cause of this finding. The patient was treated with high-dose steroids, cyclophosphamide, and plasmapheresis with resolution of hydronephrosis. Although the patient required dialysis at initiation of therapy, she went on to recover sufficient renal function to discontinue dialysis. We review the literature on the treatment of hepatitis B-associated PAN and discuss the pitfalls in diagnosis of this condition.

20/835. Differences in liver pathology and clinical outcome between two patients with hepatitis b virus and graft versus host disease.

    Our two patients undergoing allogeneic bone marrow transplantation (AlloBMT) had both hepatitis b virus (HBV) and graft-versus-host disease (GVHD). In the first patient, liver enzymes elevated three months after AlloBMT, and GVHD was diagnosed. Two weeks after the diagnosis of GVHD, HBsAg appeared in his serum. At that time, liver biopsy was not able to discriminate two disorders, but his sequential liver biopsies disclosed GVHD. Despite the patient was treated with cyclosporin A (CsA), he died for chronic GVHD. In contrast to the first patient, the second patient had HBsAg prior to GVHD. His liver enzymes deterioration was detected in the first month after AlloBMT, and reached the highest level in the third month while withdrawing CsA. In the fifth month he developed scleradermatous skin changes, and skin biopsy revealed chronic GVHD, whereas concurrent liver biopsy revealed chronic active hepatitis. This observation showed that immunosuppressive conditions such as GVHD or its prophylaxis may affect the appearance of liver pathology caused by HBV, which depends on the time of GVHD development, and the duration and depth of GVHD prophylaxis.
