Development of nodular regenerative hyperplasia (NRH) with portal hypertension following the administration of oxaliplatin for the recurrence of colon cancer.

Nodular regenerative hyperplasia (NRH) is associated with autoimmune and hematologic diseases and may lead to portal hypertension. We herein report a case of NRH diagnosed based on a liver biopsy. A 63-year-old woman developed esophageal varices and splenomegaly.

Branched-chain amino acids suppress the cumulative recurrence of hepatocellular carcinoma under conditions of insulin-resistance.

Branched-chain amino acids (BCAAs) reportedly inhibit the incidence of hepatocellular carcinoma (HCC) in patients with liver cirrhosis and obesity that is frequently associated with insulin resistance (IR). We previously reported that BCAAs exert a chemopreventive effect against HCC under IR conditions in rats. The aim of the present study was to examine the effect of BCAAs on the cumulative recurrence of HCC under IR conditions in the clinical practice.

A case of severe acalculous cholecystitis associated with sorafenib treatment for advanced hepatocellular carcinoma.

Sorafenib, a multikinase inhibitor, is the first and only drug, which improves significantly the overall survival in patients with advanced hepatocellular carcinoma (HCC). However, many patients experience diverse side effects, some of them severe and unexpected. To date, acute acalculous cholecystitis has not been documented in association with a HCC patient treated with sorafenib.

ADAMTS13 activity may predict the cumulative survival of patients with liver cirrhosis in comparison with the Child-Turcotte-Pugh score and the Model for End-Stage Liver Disease score.

Aim:   Decreased plasma ADAMTS13 activity (ADAMTS13:AC) results in accumulation of unusually large von Willebrand factor multimers and platelet thrombi formation. Our aim was to evaluate whether ADAMTS13:AC is a prognostic marker in patients with liver cirrhosis.

Methods:   Plasma ADAMTS13:AC and its related parameters were examined in 108 cirrhotic patients.

Combination of branched-chain amino acid and angiotensin-converting enzyme inhibitor improves liver fibrosis progression in patients with cirrhosis.

An effective therapeutic strategy for suppressing liver fibrosis should improve the overall prognosis of patients with chronic liver diseases. Although enormous efforts are ongoing to develop anti-fibrotic agents, no drugs have yet been approved as anti-fibrotic agents for humans. Insulin resistance (IR) is reportedly involved in the progression of liver fibrosis.

Combination of branched-chain amino acids and angiotensin-converting enzyme inhibitor suppresses the cumulative recurrence of hepatocellular carcinoma: a randomized control trial.

Insulin resistance (IR) is reportedly involved in the progression of hepatocellular carcinoma (HCC). Since neovascularization plays an important role in hepatocarcinogenesis and IR, an angiostatic therapy may be considered as one of the promising approaches for chemoprevention against HCC. The aim of the current study was to examine the combination effect of a clinically used branched-chain amino acid (BCAA) and an angiotensin-converting enzyme inhibitor (ACE-I), both reportedly possess anti-angiogenic and IR-improving activities, on the cumulative recurrence after curative therapy.

Salvage living donor liver transplantation after percutaneous transluminal angioplasty for recurrent Budd-Chiari syndrome: a case report.

Introduction: Budd-Chiari syndrome is a very rare pathological entity that ultimately leads to liver failure. Several therapeutic modalities, including percutaneous transluminal angioplasty, have been attempted to save the life of patients with Budd-Chiari syndrome. Few reports have described a salvage living donor liver transplantation performed after percutaneous transluminal angioplasty in a patient with acute Budd-Chiari syndrome.

Soluble VEGF receptor-2 may be a predictive marker of anti-angiogenic therapy with clinically available safe agents.

The identification of biomarkers of anti-angiogenic therapy that predict clinical benefit is of vital importance. We previously reported that a combination treatment with clinically available safe agents, specifically angiotensin-converting enzyme inhibitor (ACE-I) and vitamin K (VK), inhibited the cumulative recurrence of hepatocellular carcinoma (HCC) via suppression of the vascular endothelial growth factor (VEGF). The present study aimed to identify non-invasive biological markers that predict the clinically beneficial effect of this combination regimen.

Pseudomembranous colitis complicating ulcerative colitis.

Clostridium difficile toxin (CD toxin) causes antibiotic-associated colitis, or pseudomembranous colitis (PMC). Although CD toxin is sometimes found in the stools of patients with ulcerative colitis (UC), UC is rarely complicated by PMC. We report herein a case of PMC complicating UC, and present a review of the literature.

Crosstalk between angiogenesis, cytokeratin-18, and insulin resistance in the progression of non-alcoholic steatohepatitis.

Aim: To elucidate the possible crosstalk between angiogenesis, cytokeratin-18 (CK-18), and insulin resistance (IR) especially in patients with non-alcoholic steatohepatitis (NASH).

Methods: Twenty-eight patients with NASH and 11 with simple fatty liver disease (FL) were enrolled in this study and underwent clinicopathological examination. The measures of angiogenesis, CK-18, and IR employed were CD34-immunopositive vessels, CK-18-immunopositive cells, and homeostasis model assessment of IR (HOMA-IR), respectively.

Combination of vitamin K2 and angiotensin-converting enzyme inhibitor ameliorates cumulative recurrence of hepatocellular carcinoma.

Background/aims: No chemopreventive agent has been approved against hepatocellular carcinoma (HCC) yet. Since neovascularization plays a pivotal role in HCC, an angiostatic agent is considered as one of the promising approaches. The aim of this study was to elucidate the combined effect of the clinically used vitamin K(2) (VK) and angiotensin-converting enzyme inhibitor (ACE-I) on cumulative recurrence after curative treatment on a total of 87 patients, especially in consideration of neovascularization.

Development of hepatocellular carcinoma in a patient 13 years after sustained virological response to interferon against chronic hepatitis C: a case report.

Background: Although several recent reports have shown that hepatocellular carcinoma (HCC) developed in patients with chronic hepatitis C (CH-C) even after having a sustained virological response (SVR) to interferon (IFN) therapy, it is not common for HCC to develop more than 10 years after SVR.

Case Presentation: A 73-year-old Japanese man with CH-C who achieved SVR to IFN therapy 13 years ago was admitted into our hospital because of huge multiple liver tumors along with marked elevation of the tumor markers. Several diagnostic modalities strongly suggested HCC, and we performed histopathological examination.

Pneumatosis cystoides intestinalis following alpha-glucosidase inhibitor treatment: a case report and review of the literature.

A 69-year-old man was diagnosed as having myasthenia gravis (MG) in September 2004, and treated with thymectomy and prednisolone. He was then diagnosed as having steroid-induced diabetes mellitus, and received sulfonylurea (SU) therapy in May 2005. An alpha-glucosidase inhibitor (alphaGI) was added in March 2006, resulting in good glycemic control.

Eosinophilic cholecystitis along with pericarditis caused by Ascaris lumbricoides: a case report.

Although the etiology of eosinophilic cholecystitis is still obscure, the postulated causes include allergies, parasites, hypereosinophilic syndrome, and eosinophilic gastroenteritis. It is sometimes accompanied by several complications, but a simultaneous onset with pericarditis is very rare. A 28-year-old woman complained of acute right hypocondrial pain and dyspnea associated with systemic eruption.

Combined treatment of vitamin K2 and angiotensin-converting enzyme inhibitor ameliorates hepatic dysplastic nodule in a patient with liver cirrhosis.

Although it is well known that the hepatocellular carcinoma (HCC) is an ominous complication in patients with liver cirrhosis, there has been no approved drug to prevent the development of HCC to date. We previously reported that the combined treatment of vitamin K2 (VK) and angiotensin-converting enzyme inhibitor (ACE-I) significantly suppressed the experimental hepatocarcinogenesis. A 66-year-old Japanese woman with hepatitis C virus (HCV)-related liver cirrhosis developed a dysplastic nodule in the liver detected by enhanced computed tomography along with elevation of the tumor markers, namely, alpha-fetoprotein (AFP) and lectin-reactive demarcation (AFP-L3), suggesting the presence of latent HCC.

Cystic echinococcosis in immigrant from Peru: first case treated with percutaneous treatment in Japan.

We report a case of cystic echinococcosis (CE) caused by Echinococcusgranulosus, for which a modified percutaneous evacuation (PEVAC) treatment was applied. The patient had immigrated from Peru to Japan and had 2 hydatid cystic masses, 1 located in segment (S)5 of the liver and the other in S3 (5.3 and 3.

Interferon augments the anti-fibrotic activity of an angiotensin-converting enzyme inhibitor in patients with refractory chronic hepatitis C.

Aim: To evaluate the effect of combination treatment with the interferon (IFN) and angiotensin-converting enzyme inhibitor (ACE-I) on several fibrotic indices in patients with refractory chronic hepatitis C (CHC).

Methods: Perindopril (an ACE-I; 4 mg/d) and/or natural IFN (3 MU/L; 3 times a week) were administered for 12 mo to refractory CHC patients, and several indices of serum fibrosis markers were analyzed.

Results: ACE-I decreased the serum fibrosis markers, whereas single treatment with IFN did not exert these inhibitory effects.

Decreased activity of plasma ADAMTS13 may contribute to the development of liver disturbance and multiorgan failure in patients with alcoholic hepatitis.

Background: The pathogenesis of alcoholic hepatitis (AH) remains unclear and the prognosis of severe alcoholic hepatitis (SAH) is very poor. Deficiency of von Willebrand factor (VWF)-cleaving protease (VWF-CP/ADAMTS13) results in an increase of the plasma unusually large VWF multimer and leads to platelet clumping, which causes microcirculatory disturbance and finally multiorgan failure. The aim of this study was to explore the potential role of ADAMTS13 on the development of liver disturbance and multiorgan failure in AH.

Intrahepatic cholangiocarcinoma associated with central calcification and arterio-portal shunt.

Although several diagnostic imaging modalities have been significantly improved in the recent years, the definitive diagnosis of intrahepatic cholangiocarcinoma (IHC) is still sometimes difficult because of the versatile features of IHC with each imaging. A 68-year-old Japanese man with alcoholic liver cirrhosis developed an intrahepatic tumor. Several imaging modalities demonstrated various features, such as central calcification and arterio-portal (A-P) shunt.
