1/181. Chronic hepatitis B and neurogenic muscle disease: case report.

    A 17 year-old boy with chronic hepatitis B who developed left-sided muscle wasting is reported. When other possible known diseases as the cause of the neurogenic muscle disease were excluded it was hypothesised that there was a relation between the chronic hepatitis B infection and the neurogenic muscle disease. An immunopathogenesis could be explained by the presence of HBsAg in the cerebral spinal fluid.

2/181. Primary hepatic angiosarcoma: report of a case involving environmental arsenic exposure.

    Hepatic angiosarcoma is a rare malignant tumor with a rapidly fatal course. It has become a subject of interest because of its intimate relationship with environmental carcinogens, such as thorium dioxide (Thorotrast), vinyl chloride monomer, and arsenic. We describe a case of a chronic hepatitis B surface antigen carrier, with a 20-year history of environmental exposure to arsenical-containing agricultural herbicides and bactericides, who developed a hepatic angiosarcoma. He died due to rupture of the hepatic angiosarcoma with acute hemoperitoneum 9 weeks after initial diagnosis. This is a rare case of primary hepatic sarcoma, especially in taiwan where hepatocellular carcinoma is endemic. This case not only serves to give more evidence of the relationship between hepatic angiosarcoma and arsenical exposure, but also demonstrates the key point in the differential diagnosis of liver tumors. Increased familiarity with this disease will facilitate correct diagnosis and help to improve management of the condition in the future.

3/181. Combined hepatocellular-cholangiocarcinoma. Diagnostic challenge in hepatic fine needle aspiration biopsy.

    OBJECTIVE: To study the cytohistologic features of combined hepatocellular-cholangiocarcinoma (CHCC-CC) in fine needle aspiration biopsy (FNAB) material. STUDY DESIGN: Six hepatic FNAB cases with cell blocks (five) and hepatic resections (two) were analyzed cytohistologically and immunohistochemically. RESULTS: The six cases were diagnosed as CHCC-CC based on clinicopathologic correlation. Unequivocal hepatocellular carcinoma (HCC) cells corresponding to Edmondson and Steiner's grade 3 lesions were identified in the FNAB in three instances. adenocarcinoma, represented by cohesive columnar cells with ovoid, basal nuclei displaying nuclear palisading, acini and/or papillary structures with variable intracytoplasmic intraacinar or brush border mucin production, was identified in all cases. Intermediate cells with hybrid/polymorphic cytologic features straddling malignant hepatocytes and glandular cells were identified in five instances. Tissue alpha-fetoprotein was negative. There was brush border and/or diffuse cytoplasmic p-carcinoembryonic antigen immunoreactivity in the glandular elements. CONCLUSION: FNAB diagnosis of CHCC-CC is possible if the clinical, cytohistologic and immunohistochemical findings support the presence of HCC and adenocarcinoma. Intermediate cells pose a great challenge to recognize and define: they tend to lose the classic cytologic features of malignant hepatocytes and acquire glandular characteristics. At the very least, there should be a high index of suspicion. These cases underscore the necessity for clinicopathologic correlation in enhancing the precision of FNAB diagnoses.

4/181. Highly active antiretroviral therapy used to treat concurrent hepatitis B and human immunodeficiency virus infections.

    We report a case of simultaneous infection with hepatitis b virus (HBV) and human immunodeficiency virus type 1 (hiv-1) in a 26-year-old Japanese homosexual man. He was admitted to our hospital for acute hepatitis caused by HBV. At that time, HIV-1antibody (Ab) was not detected in his serum. After 6 months, he was readmitted to our hospital for further examination of his liver because of confined liver enzyme abnormalities. Anti-HIV- Ab was detected in his serum by both enzyme immunosorbent assay (EIA) and particle agglutination (PA). His serum hiv-1 RNA level was 50 x 10(4) copies/ml and serum levels of HBV dna polymerase (dna-P) and HBV dna were 6535cpm and 3 plus (>1000 copies/ml). His clinical course and laboratory data suggested progression from acute to chronic hepatitis related to coinfection with hiv-1. The diagnosis was chronic active hepatitis caused by HBV as an opportunistic infection due to coinfection with hiv-1. We began highly active antiretroviral therapy (HAART) because interferon (IFN) therapy was ineffective. HAART was started at an initial dosage of 600 mg zidovudine (AZT), 300 mg lamivudine (3TC), and 2400 mg indinavir (IDV) daily. After 4 weeks, the serum level of HBV dna-polymerase (p) had decreased markedly to 37cpm and that of hiv-1 RNA had decreased to below the sensitivity threshold, indicating considerable suppression of the replication of these viruses by the treatment. But HBV dna remained at low levels. Although the incidence of HBV infection in patients with hiv-1 infection has been reported to be high in the united states and europe, simultaneous HBV and hiv-1 infection leading to persistent HBV infection is rare.

5/181. Successful treatment of decompensated chronic viral hepatitis by bursal disease virus vaccine.

    Three cases of women with chronic liver inflammation caused by hepatitis B (two) and C (one) viral infections, were followed up to twelve years after diagnosis. As conventional therapy was ineffective and the patients progressed into decompensated liver disease, they were superinfected with massive doses of an attenuated variant (MTH-68/B) of the apathogenic avian Bursal Disease virus (a double-stranded RNA virus from the birnaviridae family). Clinical symptoms and biochemical abnormalities were resolved in two patients following few months of virus treatment. Cirrhosis was stabilized and significant clinical improvement was achieved in the third patient--who before the virus therapy was moribund with recurring, diuretic-resistant ascites, variceal bleedings, portal encephalopathy and renal failure. To our knowledge, these are the first recorded cases of decompensated chronic viral hepatitis which went to long-lasting remission or were stabilized by superinfection with an apathogenic virus.

6/181. Prominent effect of immunoadsorption plasmapheresis therapy in a patient with chronic inflammatory demyelinating polyneuropathy associated with hepatitis B infection.

    We encountered a patient with chronic inflammatory demyelinating polyneuropathy associated with hepatitis B infection. Immunohistochemical study revealed the deposition of immune complex composed of hepatitis B surface antigen (HBsAg) both around the endoneural capillary and in the endoneurium. Neurological signs were significantly improved by immunoadsorption plasmapheresis (IAPP) treatment without incorporating corticosteroid hormone therapy; weekly long-term IAPP has successfully maintained the patient's condition.

7/181. Rapid evolution of chronic viral hepatitis into hepatocellular carcinoma after beta-interferon treatment.

    A 62-year-old man, affected by Chronic Active Hepatitis (discovered in 1993) and treated with interferon, referred to our department with increased abdominal volume, persistent abdominal pain, continuous-remittent fever and jaundice. CT scan of the liver revealed a hypodense, not capsulated, infiltrative, solid formation in the right lobe. US guided biopsy showed multinucleated giant cells, with eosinophilic cytoplasm and pleomorphism of the nuclei, arranged in several thick trabecula lined by endothelial cells or formed bile containing acini. In our case, the rapid evolution of chronic viral hepatitis towards HCC calls for a careful evaluation of the role of IFN therapy, since this drug is widely used in chronic liver diseases.

8/181. An unusual cause of back pain.

    This case describes what may become an increasingly common clinical problem in australia as the proportion of our population originally derived from South East asia, ages. Our patient was of Chinese origin and presented with back pain which was eventually found to be due to metastatic disease from an otherwise silent hepatoma, in association with unrecognised chronic hepatitis B infection.

9/181. Antiviral treatment for human immunodeficiency virus patients co-infected with hepatitis b virus: combined effect for both infections, an obtainable goal?

    A large percentage of human immunodeficiency virus (HIV) patients have serological evidence of a past or present hepatitis b virus infection (HBV). Long-term survival is increasing for HIV patients because of highly active antiretroviral therapy. Therefore, the chronic hepatitis B infection may become an important determinant of disease outcome in these co-infected patients. We describe two HIV/HBV co-infected patients who were treated with extended antiviral therapy, initially indicated for the HIV infection. lamivudine, a suppressor of viral replication in both infections, was one of these antiviral drugs. One patient showed a severe rebound of the HBV after withdrawal of lamivudine, the other patient developed a mutant hepatitis b virus after 18 months of treatment. This mutation was exclusively induced by lamivudine. These patients show that, with improved HIV-related survival, the HBV infection should be monitored carefully, thereby enabling the physician to interfere with therapy when necessary.

10/181. A novel deletion mutant of hepatitis b virus surface antigen.

    HBsAg is the most important serological marker for acute or chronic hepatitis B. Nevertheless, there are reports of HBsAg-negative virus carriers, either with anti-HBc as the only marker for hepatitis b virus (HBV) infection or even positive for anti-HBs and anti-HBc. We report isolates from a patient, in which a deletion in the HBs-gene was associated with persisting viremia in the presence of anti-HBs. The 62-year-old female, infected most likely by her husband, had detectable markers of chronic active hepatitis B, such as HBsAg, HBeAg, and anti-HBc-IgM, for 2 years. The patient then seroconverted to anti-HBs, although HBeAg and anti-HBc-IgM remained detectable. At this time, semiquantitative polymerase chain reaction showed about 10(4) viral genomes per milliliter of serum. Direct sequencing of the amplified products revealed a major population of dna molecules with a deletion of nucleotide 31 of the HBs-gene, which up to now has not been described. This deletion led to a frame-shift and introduced a stop-codon after 21 amino acids of the sHBsAg. We suspect that this deletion, and the resulting HBsAg lacking the major epitopes recognized by specific antibodies, could favor ongoing viral replication, despite the presence of anti-HBs. However, because the reading frame of the polymerase was also severely damaged by this deletion, it is assumed that a minor population of intact genomes was present to help in the formation of virus particles.
