Formulation for Effective Screening and Management of Nonalcoholic Steatohepatitis: Noninvasive NAFLD Management Strategy.

To establish a versatile means for screening and management of nonalcoholic steatohepatitis (NASH), shear wave velocity was measured in 20 normal controls and 138 consecutive nonalcoholic fatty liver disease (NAFLD) cases. Referencing biochemical properties in 679 healthy volunteers, a formula to distinguish NASH suspects was established and validated in another cohort of 138 histologically proven NAFLD cases. NASH and simple steatosis (SS) suspects were selected based on a plot of shear wave velocity against age.

Percutaneous transhepatic portal vein stent placement can improve prognosis for hepatocellular carcinoma patients with portal vein tumor thrombosis.

Background/aims: Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) has an extremely poor prognosis. One reason is that portal hypertension may progress rapidly and intractable gastric/esophageal variceal hemorrhage may occur in PVTT cases. We studied whether a percutaneous transhepatic portal vein stent placement could improve the prognosis for HCC with PVTT.

Improved method for transjugular liver biopsy using imaging sheaths developed for balloon-occluded retrograde transvenous obliteration.

Background/aims: Patients with ascites or coagulation abnormalities and requiring a liver biopsy may undergo transjugular liver biopsy (TJLB) rather than percutaneous liver biopsy. Currently, the difficulty in maneuvering the sheath towards the hepatic vein keeps this procedure from being widely used. Therefore, the utility of imaging sheaths, typically used for balloon-occluded retrograde transvenous obliteration, during TJLB was examined.

Surfactant protein-D is more useful than Krebs von den Lungen 6 as a marker for the early diagnosis of interstitial pneumonitis during pegylated interferon treatment for chronic hepatitis C.

Background/aims: To examine the usefulness of serum Krebs von den Lungen 6 (KL-6) and surfactant protein-D (SP-D) as markers of interstitial pneumonitis. Many antiviral therapies have become available for chronic hepatitis C, including pegylated interferon (PEGIFN) plus ribavirin. Since interstitial pneumonitis is a serious adverse drug reaction during interferon therapy, interferon treatment requires caution in respiratory disease patients.

Histopathology of the tissue adhering to the multiple tine expandable electrodes used for radiofrequency ablation of hepatocellular carcinoma predicts local recurrence.

Objective: To assess the ability to predict the local recurrence of hepatocellular carcinoma by analyzing tissues adhering to the radiofrequency ablation probe after complete ablation.

Methods: From May 2002 to March 2011, tissue specimens adhering to the radiofrequency ablation probe from 284 radiofrequency ablation sessions performed for hepatocellular carcinomas ≤3 cm in size were analyzed. The specimens were classified as either viable tumor tissue or complete necrosis, and the local recurrence rates were calculated using the Kaplan-Meier method.

Efficacy of the regimen using twice-daily β-interferon followed by the standard of care for chronic hepatitis C genotype 1b with high viral load.

Aim:   In patients with refractory genotype 1b chronic hepatitis C with high viral loads, we retrospectively compared the efficacy of standard of care treatment (SOC: combined PEG-IFN-α-2b/ribavirin for 48 weeks) and a regimen in which 2 weeks of SOC induction was replaced by twice-daily β-interferon alone (IFN-β induction therapy).

Methods:   Seventeen patients received the IFN-β induction therapy plus SOC (IFN-β induction group) and 13 patients received SOC alone (SOC group).

Results:   In the IFN-β induction group and SOC group, early virological response (EVR) rates were 88.

Antioxidant properties of ferulic acid and its related compounds.

Antioxidant activity of 24 ferulic acid related compounds together with 6 gallic acid related compounds was evaluated using several different physical systems as well as their radical scavenging activity. The radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) decreased in the order caffeic acid > sinapic acid > ferulic acid > ferulic acid esters > p-coumaric acid. In bulk methyl linoleate, test hydroxycinnamic acids and ferulic acid esters showed antioxidant activity in parallel with their radical scavenging activity.
