Hemorrhagic varices around the pancreatojejunostomy site due to left-sided portal hypertension after pancreaticoduodenectomy: A case report.

Pancreaticoduodenectomy (PD) with combined portal vein resection sometimes causes left-sided portal hypertension, which can be a problem. An appropriate treatment strategy for hemorrhagic ectopic varices due to left-sided portal hypertension after PD has not yet been determined. We report a case of repeated variceal rupture around the pancreatojejunostomy site.

[A case of invasive intraductal papillary mucinous carcinoma arising from jejunal heterotopic pancreas].

Intraductal papillary mucinous carcinoma (IPMC) arising from the heterotopic pancreas is rare. A case of IPMC metastasis from the jejunal heterotopic pancreas was described. The heterotopic pancreas could be the source of the submucosal tumor-like lesion found in the small intestine with an elevated carbohydrate antigen (CA) 19-9 level.

Pancreatic hyperechogenicity associated with hypoadiponectinemia and insulin resistance: A Japanese population study.

Aim: To examine the relationship between pancreatic hyperechogenicity and risk factors for metabolic syndrome.

Methods: A general population-based survey of lifestyle-related diseases was conducted from 2005 to 2006 in Japan. The study involved 551 participants older than 40 year of age.

Relationship between tumor necrosis factor-α release and granulocyte and monocyte adsorption to cellulose acetate beads.

Tumor necrosis factor-α, (TNF)-α, a proinflammatory cytokine, is produced by activated granulocytes and monocytes (GMs) and implicated as a major factor in inflammatory bowel disease (IBD) pathogenesis. Reduction of TNF-α should improve IBD pathology. GM adsorptive apheresis (GMA) is an effective therapy for inflammatory disorders including IBD.

Epiregulin promotes the emergence and proliferation of adult liver progenitor cells.

We have previously reported that epiregulin is a growth factor that seems to act on liver progenitor cells (LPCs) during liver regeneration. However, the relationship between epiregulin and LPCs has remained unclear. The aim of the present study was to clarify the role of epiregulin during liver regeneration.

Possible autoimmune hepatitis induced after chronic active Epstein-Barr virus infection.

Chronic active Epstein-Barr virus infection (CAEBV) can be manifested in a variety of systemic conditions, including interstitial pneumonia, malignant lymphoma, and coronary aneurysm. Sometimes it may be associated with hepatic failure, although the mechanism underlying CAEBV-related hepatotoxicity remains unclear. We encountered a case of autoimmune hepatitis (AIH) associated with CAEBV.

A case of adult type 1 Gaucher disease complicated by temporal intestinal hemorrhage.

A 21-year-old man with a history of sudden rectal hemorrhage was referred to our hospital. Examination disclosed thrombocytopenia and hepatosplenomegaly. A liver biopsy specimen demonstrated Gaucher cells in Glisson's capsule.

Dynamics of serum metabolites in patients with chronic hepatitis C receiving pegylated interferon plus ribavirin: a metabolomics analysis.

Objectives: Serum samples from patients with chronic hepatitis C were subjected to metabolomics analysis to clarify the pretreatment characteristics of their metabolites and also changes in specific metabolites resulting from antiviral therapy with pegylated interferon plus ribavirin (PegIFN/RBV).

Materials/methods: The serum levels of low-molecular-weight metabolites in the twenty patients before and 24weeks after completion of PegIFN/RBV therapy were analyzed using capillary electrophoresis and liquid chromatography-mass spectrometry.

Results: Ten patients showed a non-virological response (NVR) and 10 achieved a sustained virological response (SVR) with eradication of viremia.

Serum prolactin levels and prolactin mRNA expression in peripheral blood mononuclear cells in hepatitis C virus infection.

Prolactin is not only a pituitary hormone but an immunoregulatory hormone secreted from lymphocytes. Prolactin induction in relation to hepatitis C virus (HCV) infection has not been elucidated. The serum levels of prolactin were examined in 232 HCV-infected subjects positive for anti-HCV antibody and 65 healthy controls negative for it, who were recruited in the cohort study.

Impaired mitochondrial β-oxidation in patients with chronic hepatitis C: relation with viral load and insulin resistance.

Background: Hepatic steatosis is often seen in patients with chronic hepatitis C (CH-C). It is still unclear whether these patients have an impaired mitochondrial β-oxidation. In this study we assessed mitochondrial β-oxidation in CH-C patients by investigating ketogenesis during fasting.

Clinical manifestations of liver injury in patients with anorexia nervosa.

Aim: The number of Japanese patients with anorexia nervosa (AN) is increasing as society changes. Mild liver injury is a complication of AN in around 30% of cases. In some rare instances, patients present with severe liver injury similar to acute liver failure.

Production of interleukin-10 by combining a granulocyte and monocyte adsorption carrier with ulinastatin.

Interleukin (IL)-10 is an anti-inflammatory cytokine mainly produced by monocytes and is essential for the induction of anti-inflammatory intestinal macrophages with macrophage colony-stimulating factor (M-CSF). Thus, IL-10- and M-CSF-rich conditions in colonic tissues seem to contribute to the improvement of pathological conditions in patients with inflammatory bowel diseases (IBD). We have already reported that ulinastatin, a serine protease inhibitor, increases M-CSF production during granulocyte/monocyte (GM) adsorption to cellulose acetate (CA) beads (carriers for Adacolumn therapy).

Evaluation of the effect of ulinastatin on the production of macrophage colony-stimulating factor in vitro for potential combination therapy with leukocyte adsorption.

Macrophage colony-stimulating factor (M-CSF) induces normal intestinal macrophages that have anti-inflammatory effects. Thus, M-CSF-rich conditions in colonic tissues seem to contribute to the improvement of pathological conditions in patients with inflammatory bowel diseases (IBD). However, it has not been clarified whether current therapies for IBD, including granulocyte/monocyte adsorptive apheresis using an Adacolumn, and ulinastatin, a serine protease inhibitor, affect the production of M-CSF.

A case of monocular blindness as the initial presentation of hepatocellular carcinoma with skull metastasis.

A 52-year-old man suffering from monocular blindness, with light perception only, was admitted to our hospital. The symptom had begun as low vision and developed rapidly within 3 weeks into monocular blindness in the right eye, with no other systemic manifestations. Imaging examinations revealed multiple hepatocellular carcinomas in the cirrhotic liver, and tumors at the skull base and vertebra.

(99m)Tc-GSA SPECT analysis was clinically useful to evaluate the effect of interferon in a patient with interferon non-responsive chronic hepatitis C.

We describe a 62-year-old woman with advanced chronic hepatitis C who showed no response to low-dose long-term interferon-beta monotherapy (3 MU, three times a week). The interferon monotherapy was continued for 2 years and 9 months. Despite this lack of response to interferon, the patient's clinical course was good and liver function assessed by (99m)Tc-galactosyl human serum albumin single photon emission computed tomography ((99m)Tc-GSA SPECT) analysis improved significantly.

Potential therapeutic application of intravenous autologous bone marrow infusion in patients with alcoholic liver cirrhosis.

The present study was conducted to evaluate the application and efficacy of autologous bone marrow infusion (ABMi) for improvement of liver function in patients with alcoholic liver cirrhosis (ALC). Five subjects and 5 control patients with ALC who had abstained from alcohol intake for 24 weeks before the study were enrolled. Autologous bone marrow cells were washed and injected intravenously, and the changes in serum liver function parameters, and the level of the type IV collagen 7S domain as a marker of fibrosis, were monitored for 24 weeks.

Enhanced expression of fibroblast growth factor 2 in bone marrow cells and its potential role in the differentiation of hepatic epithelial stem-like cells into the hepatocyte lineage.

The transplantation of bone marrow cells (BMCs) has been applied in liver regenerative cell therapy. However, details of the interaction between the transplanted BMCs and hepatic stem cells have not been elucidated. The aim of the present study was to investigate the interaction of BMCs with hepatic stem-like cells (HSLCs) and to determine the BMC factor that steers HSLC differentiation into the hepatocyte lineage.

Release of interleukin-1 receptor antagonist by combining a leukocyte adsorption carrier with ulinastatin.

Both granulocyte/monocyte adsorptive apheresis (GMA) and ulinastatin, a serine protease inhibitor, are reported to be effective in patients with ulcerative colitis; however, combination therapy with GMA and ulinastatin has not been attempted. Investigating the effect of ulinastatin on GMA is required for combination therapy since the inhibition of serine protease suppresses the reaction of GMA. To clarify the effects of ulinastatin on GMA, we investigated whether granulocyte adsorption to cellulose acetate beads (carriers for GMA) and interleukin-1 receptor antagonist (IL-1ra) release were inhibited by ulinastatin.

Secondary structure of the amino-terminal region of HCV NS3 and virological response to pegylated interferon plus ribavirin therapy for chronic hepatitis C.

The aim of the study was to identify a predictive marker for the virological response in hepatitis C virus 1b (HCV-1b)-infected patients treated with pegylated interferon plus ribavirin therapy. A total of 139 patients with chronic hepatitis C who received therapy for 48 weeks were enrolled. The secondary structure of the 120 residues of the amino-terminal HCV-1b non-structural region 3 (NS3) deduced from the amino acid sequence was classified into two major groups: A and B.

Relationship between alcohol consumption and serum adiponectin levels: the Takahata study--a cross-sectional study of a healthy Japanese population.

Context: The relationship between alcohol consumption and serum adiponectin levels has not been fully explored in an Asian population.

Objective: Our goal was to determine whether alcohol consumption is associated with a change in adiponectin levels in a healthy Japanese population.

Design: This was a cross-sectional study.

Biological effect of anaphylatoxin C5a on the generation of anti-inflammatory substances in leukocyte adsorption.

Anaphylatoxins, which are involved in both pro-inflammatory processes and a variety of anti-inflammatory effects, are produced during granulocyte and monocyte adsorptive apheresis. We noticed the anti-inflammatory effects of C5a, the strongest anaphylatoxin, in granulocyte and monocyte adsorptive apheresis. The aim of this study was to investigate the effect of C5a on interleukin-1 receptor antagonist (IL-1ra) and hepatocyte growth factor (HGF) generation in granulocyte and monocyte adsorption.

Impact of metabolic syndrome on elevated serum alanine aminotransferase levels in the Japanese population.

Measurement of the serum alanine aminotransferase (ALT) level is used as an initial test for detection of liver diseases, and recent studies have also highlighted its potential value as a measure of overall health and survival as a marker of an increased risk of metabolic disorder. This study was designed to clarify the prevalence of elevated ALT levels in the Japanese population and to assess factors associated with ALT elevation. The subjects were 2165 individuals aged 40 to 85 years who participated in a Japanese community-based study referred to as the Takahata Study.

[Case of chronic type C hepatitis complicated with idiopathic thrombocytopenic purpura that was successfully treated by interferon therapy].

We report a case of chronic hepatitis C complicated with idiopathic thrombocytopenic purpura (ITP), successfully treated with interferon (IFN) beta. A 65-year-old woman was admitted to our hospital for the treatment of chronic hepatitis C with IFN beta. ITP was also diagnosed because of the presence of platelet associated IgG and the findings of bone marrow examination.

[Two cases of pyogenic spondylitis with chronic hepatitis C during combination therapy of interferon alfa and ribavirin].

This report describes our experience with two cases of pyogenic spondylitis with chronic hepatitis C during combination therapy of interferon alfa and ribavirin. The first patient, a 59-year-old man, was treated conservatively and improved, but the second patient, a 69-year-old woman, was not improved by conservative therapy and reconstructive operation was performed. The combination therapy of interferon alfa and ribavirin has a high risk of severe infectious diseases as side effects.
