Abstract
Liver diseases associated with hepatitis C virus (HCV) infection have become the major cause of mortality in patients with human immunodeficiency virus (HIV) infection since the introduction of highly active anti-retroviral therapy. HCV-related liver disease is more severe in HIV-infected patients than in non-HIV-infected patients, but the standard therapies used to treat chronic hepatitis C in HCV/HIV coinfected patients are the same as those for patients infected with HCV alone. HIV protease inhibitors might have potential to down-regulate HCV load of HCV/HIV coinfected patients. In this study, we evaluated the effects of nelfinavir on intracellular HCV replication using the HCV replicon system. We constructed an HCV replicon expressing a neomycin-selectable chimeric firefly luciferase reporter protein. Cytotoxicity and apoptosis induced by nelfinavir were assessed and synergism between nelfinavir and interferon (IFN) was calculated using CalcuSyn analysis. Nelfinavir dose-dependently repressed HCV replication at low concentrations (IC(50), 9.88 micromol/L). Nelfinavir failed to induce cytotoxicity or apoptosis at concentrations that inhibited HCV replication. Clinical concentrations of nelfinavir (5 micromol/L) combined with IFN showed synergistic inhibition of HCV replication in our replicon model. Our results suggest that the direct effects of nelfinavir on the HCV subgenome and its synergism with IFN could improve clinical responses to IFN therapy in HCV/HIV coinfected patients.

Abstract
The aims of this phase I/II study of docetaxel and S-1 were to determine the dose-limiting toxicity (DLT), maximum-tolerated dose (MTD), and recommended dose (RD) in the phase I part and to explore the tumour response, survival and safety in the phase II part. Patients with histologically- or cytologically confirmed unresectable or recurrent gastric cancer were eligible. Treatment consisted of intravenous docetaxel on day 1 (starting dose 50 mg m−2) and oral S-1 at a fixed dose of 40 mg m−2 twice daily on days 1–14, every 4 weeks up to six cycles. Nine patients took part in the phase I portion of the study. The MTD of docetaxel was determined to be 50 mg m−2, with the DLTs of grade 3 infection associated with grade 3 neutropenia and grade 4 neutropenia during S-1 administration. The RD of docetaxel was 40 mg m−2 in combination with S-1 40 mg m−2 b.i.d. The efficacy and safety of this regimen was therefore assessed in 46 patients with at least one measurable lesion. The overall response rate and estimated median overall survival were 46% (95% CI, 31–61%) and 14.0 months (8.3–17.3 months), respectively. The most common grade 3/4 toxicity was neutropenia (67% of patients), which was predictable and manageable. This regimen showed promising activity with moderate toxicities in advanced gastric cancer.

Abstract
OBJECTIVE To determine the prevalence of fatty liver and alanine aminotransferase (ALT) elevation in obese Japanese women and to clarify the factors contributing to fatty change and ALT elevation in the cohort. DESIGN Cross-sectional and population-based study. SUBJECTS From 4366 women who received their annual health check-up, 4211 women were selected for analysis. All 4211 women were negative for hepatitis virus markers. MEASUREMENTS Peripheral blood cell counts, liver biochemical tests, fasting glucose, cholesterol and triglyceride levels, uric acids, glycosylate hemoglobin A1c, and ultrasound examination. RESULTS Ultrasonographic evidence of fatty liver and ALT elevation was seen in 391 (9.3%) and 238 (5.7%), respectively, of the 4211 women. Frequencies of both fatty liver and ALT elevation increased with increase in the degree of obesity. The frequency of ALT elevation was higher in women with fatty liver than in women without fatty liver among the nonobese or mildly obese group. However, the frequency of ALT elevation was not significantly different between women with fatty liver and women without fatty liver among the severely obese group. Multivariate analysis showed that obesity, hemoglobin (> or = 14 g/dl), triglyceride (> or = 150 mg/dl), diabetes mellitus, and fatty liver were significant predictors of ALT elevation. However, only two variables, hemoglobin (> or = 14 g/dl) and presence of diabetes, were significant in the severely obese group. CONCLUSIONS ALT elevation not associated with fatty liver was frequently seen in obese women, suggesting that obesity is directly associated with the elevated ALT level in Japanese obese women. In addition, hemoglobin (> or = 14 g/dl) was a strong predictor of ALT elevation in the severely obese group.

Abstract
We established cytotoxic T-lymphocyte (CTL) lines against colonic epithelial cell line from LPLs of patients with ulcerative colitis by continuous stimulation with human lymphocyte antigen A (HLA-A) matched colonic epithelial cell lines and clones from LPLs using polyclonal stimulation with phytohemagglutinin. The established CTL lines and clones showed cytotoxicity against HLA-A-matched colonic epithelial cell line but not against HLA-mismatched colonic epithelial cell lines, and HLA-A-matched lung and esophagus cell lines. The CTL response was HLA class I-restricted and mediated by CD8-positive T-lymphocytes. Moreover, the CTL line showed cytotoxicity against autologous B-LCLs pulsed with peptides extracted from HLA-A-matched colonic epithelial cell line but not against other organ-derived peptides pulsed and unpulsed autologous B-LCLs. CTL lines and clones established from LPLs of patients with ulcerative colitis showed colon-specific and HLA class I-restricted killing of human colonic epithelial cell line, suggesting that these CTLs may play a role in colonic epithelial cell damage in some patients with ulcerative colitis.

Abstract
To clarify the correlation between hepatitis B virus (HBV) DNA levels and serum alanine aminotransferase (ALT) levels in patients with established chronic hepatitis delta virus (HDV) infection, sensitive HBV quantitative assays were used for the study. Thirty-four consecutive patients with chronic liver disease who were positive for both hepatitis B surface antigen (HBsAg) and antibody to HDV (anti-HDV), including 19 patients with chronic hepatitis, 8 patients with liver cirrhosis and 7 patients with hepatocellular carcinoma. All were negative for hepatitis Be antigen (HBeAg) and positive for antibody to HBeAg. HBV DNA was detected in 25 (73.5%) of the 34 patients using real-time detection PCR, and the HBV DNA levels of these patients were significantly lower compared with HBeAg status and ALT level-matched patients with chronic liver disease positive for HBsAg but negative for anti-HDV. There was no correlation between serum HBV DNA and ALT levels among the 34 patients with chronic liver disease positive for anti-HDV. Whereas serum ALT levels in anti-HDV-positive HBsAg carriers with HDV RNA were significantly higher than those without HDV RNA. Liver damage in patients with established chronic HDV infection may be caused mainly by ongoing HDV infection not by HBV replication.

Abstract
Newly developed hepatitis B virus (HBV)-DNA quantitative assays, transcription-mediated amplification and hybridization protection assay (TMA-HPA) and branched-DNA assay were clinically evaluated. The subjects consisted of 160 chronic HBV carriers; 48 were hepatitis Be antigen (HBeAg)-positive, whereas 109 were anti-HBe-positive (three were both negative). All subjects with HBeAg, except one, showed high HBV-DNA replication levels (>/=10(5.8) copies/ml). In HBeAg negative subjects, there was a strong correlation between the serum HBV-DNA and alanine aminotransferase (ALT) levels; ALT level was usually normal if the samples tested showed an HBV-DNA level less than 10(5)/ml, whereas, the majority of the sera with an HBV-DNA concentration greater than 10(7)copies/ml showed elevation in serum ALT level. An intermediate range of HBV-DNA level (10(5)-10(7) copies/ml) was associated with variable ALT activity. In conclusion, a serum HBV-DNA level associated with ALT elevation was lower in patients with type B chronic liver disease negative for HBeAg compared with their HBeAg-positive counterparts. There was usually no or mild liver disease activity when patients with chronic HBV infection have serum HBV-DNA levels less than 10(5)copies/ml.

Abstract
Among 39 patients with pyogenic liver abscess who were admitted to our institute, six (15%) were infected by Streptococcus milleri (S. milleri). We investigated clinical features of these six patients. There were five males and one female, aged 43-81 years old (mean: 61). Five of the six patients had underlying illness. All patients had fever, and three of them complained of abdominal pain. Three patients had mixed infections; particularly intraoral anaerobes, Fusobacterium, were found in two of the three patients. There were no differences in clinical features between patients with S. milleri liver abscess and those with other bacterial liver abscess. In conclusion, on selecting antibiotics for the treatment of liver abscess, it is necessary to consider the S. milleri and intraoral anaerobes.

Abstract
A 36-year-old man with severe alcoholic hepatitis was treated with plasma exchange combined with hemodiafiltration to remove endotoxins and inflammatory cytokines. During the treatment, he had critical arrhythmia (torsade de pointes [TdP]). His laboratory data showed hypomagnesemia, which was suspected to be responsible for the development of TdP. Patients with alcoholic liver disease tend to have hypomagnesemia and Q-T interval prolongation. Furthermore, hemodiafiltration may cause hypomagnesemia. Careful observation for electrolytic imbalance is necessary when clinicians treat patients with alcoholic liver failure with a liver support system.

Abstract
Primary biliary cirrhosis is often associated with autoimmune conditions, such as thyroid disease, sicca complex, and rheumatoid arthritis. However, an association with autoimmune hemolytic anemia has rarely been reported. We present a case of primary biliary cirrhosis associated with warm type autoimmune hemolytic anemia, and we review prior reports.

Abstract
Combined endoscopic and surgical treatment in a 14-year-old girl with Peutz-Jeghers syndrome is reported herein. The patient was diagnosed with Peutz-Jeghers syndrome because of mucocutaneous pigmentation and hamartomas of the small intestine at 10 years of age, when she underwent an emergency laparotomy for an intussusception of the small intestine. Since this diagnosis, she has undergone follow-up, and barium radiologic and endoscopic studies have shown multiple polyps of various sizes from the stomach throughout the small intestine and to the colon. This time, with the use of combined endoscopic and surgical treatment for polyps of the small intestine, 26 polyps were removed endoscopically by performing only one enterotomy. This combined technique may allow for a longer interval between laparotomies, therefore reducing the complications associated with multiple laparotomies and resections.

Abstract
Strongyloidiasis is an intestinal parasitic disease caused by Strongyloides stercoralis. Basically, detecting larvae of S. stercoralis in feces makes definitive diagnosis. The ordinary agar plate culture method developed at our department is much simpler to handle and much more sensitive than the conventional filter paper culture method. It is considered to be the most useful method in the diagnosis of strongyloidiasis and in evaluation of the eradicating effect. Among chemotherapeutic agents, thiabendazole representing the benzimidazole compounds is most effective. However, it has a problem in safety, since its adverse effects and liver dysfunction occur with a high incidence, and it can be severe. Regarding the effects of mebendazole, albendazole and ivermectin, a study was conducted which included many patients. A high incidence of liver dysfunction was observed with mebendazole, and eradicating effect was not sufficient with albendazole. Ivermectin is different from benzimidazole compounds in a pharmacokinetic profile. However, ivermectin showed a strong anthelmintic effect with the least toxicity. We therefore consider ivermectin is the most useful drug for the treatment of strongyloidiasis.

Abstract
OBJECTIVE The pathogenesis of Crohn's disease (CD) is thought to be associated with production of several cytokines, especially type-1 cytokines. To elucidate the in situ cytokine profiles in CD, cytokine-containing cells were localized by immunohistochemistry, with special attention to noncaseating granulomas. The results were compared with those from studies of ulcerative colitis (UC). METHODS We adopted the biotin-streptavidin-peroxidase method on frozen sections obtained at surgery from patients with CD or UC, and we immunohistochemically examined the expression of several cytokines (interferon-gamma, interleukin-2, -4, -10, and -12). RESULTS In normal colonic tissue, expression of these cytokines was rare except for interleukin-4. In actively inflamed areas of CD, increased expression of all cytokines by mononuclear cells was observed. In contrast, granulomas in CD involved interferon-gamma+ lymphocytes and interleukin-12+ macrophage-lineage cells (epithelioid cells and multinucleated giant cells) but few interleukin-4+ or -10+ cells. Actively inflamed areas of UC also showed an increase in the number of cytokine-containing cells; however, quantitative analysis revealed that there was more expression of interferon-gamma and interleukin-12, and less of interleukin-10, in CD than in UC, indicating the presence of more type 1 T-helper cells in CD tissue than in UC. CONCLUSIONS The findings of the present study suggest that granulomas of CD are coupled with type 1 T-helper responses; these responses may contribute to the pathogenesis of this disease.

Abstract
Hepatitis delta virus (HDV) infection is relatively common in the Miyako Islands, Okinawa, Japan, where the infection has been reported to be associated with low pathogenicity. HDV RNA extracted from each of 6 patients with HDV-related chronic liver disease living in the islands was amplified by reverse transcription-polymerase chain reaction and examined genetically to determine the HDV genotype. All isolates from the 6 patients were classified as genotype II by the neighbor-joining method. However, these isolates had relatively low homology (75-81%) to the HDV genotype II isolate reported from Japan, and showed relatively high identity (83-95%) to the novel genotype II isolate (HDV genotype IIb) recently reported from Taiwan. Phylogenetic analysis showed that the 6 isolates form a novel group within HDV genotype II. Furthermore, there was notable variation in sequence among the 6 isolates compared with the relatively close clustering of HDV isolates within limited areas (e.g., United States, Archangelos, Turkey, Albania, Peru). HDV genotype II in the Miyako Islands is therefore unique, and HDV infection may have been introduced at a relatively early time in this area.

Abstract
Factor VIII (FVIII) inhibitors appear in 3-20% of haemophilia A patients after injection of FVIII concentrates. However, autoantibodies to FVIII are also reported in non-haemophiliacs. In these patients FVIII inhibitor disappears spontaneously or diminishes in response to immunosuppressive therapy. However, a few patients show resistance to immunosuppressive therapy. We describe a non-haemophilic elderly patient with acquired FVIII inhibitor who failed to respond to prednisolone. He was treated with double-filtration plasmapheresis (DFPP) which resulted in a very rapid reduction in inhibitor levels and resolution of symptoms.
