Designing Clinical Trials in Wilson's Disease.

Background And Aims: Wilson's disease (WD) is an autosomal-recessive disorder caused by ATP7B gene mutations leading to pathological accumulation of copper in the liver and brain. Adoption of initial treatments for WD was based on empirical observations. These therapies are effective, but there are still unmet needs for which treatment modalities are being developed.

Impact of a Prohibitive Versus Restrictive Tobacco Policy on Liver Transplant Candidate Outcomes.

Tobacco use has been associated with poorer outcomes after liver transplantation (LT). Our study examined the effect on LT listing outcomes of a newly implemented policy prohibiting the use of all tobacco products compared with a prior restrictive policy. Medical records of consecutive adult patients evaluated for LT from January 2010 to July 2013 (era 1, n = 1344) and August 2013 to March 2017 (era 2, n = 1350) were reviewed.

Bis-choline tetrathiomolybdate in patients with Wilson's disease: an open-label, multicentre, phase 2 study.

Background: Wilson's disease is a genetic disorder in which copper accumulates in the liver, brain, and other tissues. Therapies are limited by efficacy, safety concerns, and multiple daily dosing. Bis-choline tetrathiomolybdate (WTX101) is an oral first-in-class copper-protein-binding molecule that targets hepatic intracellular copper and reduces plasma non-ceruloplasmin-bound copper (NCC) by forming tripartite complexes with albumin and increasing biliary copper excretion.

Sustained virologic response to therapy of recurrent hepatitis C after liver transplantation is related to early virologic response and dose adherence.

Sustained virologic response (SVR) after antiviral therapy for recurrent hepatitis C virus (HCV) infection in liver transplant (LT) recipients is consistently lower than that achieved in non-LT patients. We evaluated efficacy and safety of pegylated interferon (IFN) and ribavirin (RBV) therapy in LT recipients with recurrent HCV and factors associated with SVR. All subjects with histologic evidence of recurrent HCV were intended to be treated for 48 weeks with full-dose pegylated IFN; target dose of RBV was 800 mg/day.

Prognosis of hepatocellular carcinoma: comparison of 7 staging systems in an American cohort.

Currently there is no consensus as to which staging system is best in predicting the survival of patients with hepatocellular carcinoma (HCC). The aims of this study were to identify independent predictors of survival and to compare 7 available prognostic staging systems in patients with HCC. A total of 239 consecutive patients with cirrhosis and HCC seen between January 1, 2000, and December 31, 2003, were included.

Role of small GTP binding proteins in the growth-promoting and antiapoptotic actions of gastrin.

G17 has growth promoting and antiapoptotic effects on the AR4-2J pancreatic acinar cell line. We previously reported that whereas MAPK regulates G17-stimulation of AR4-2J cell proliferation, Akt mediates the antiapoptotic action of G17. We examined the signal-transduction pathways mediating G17 stimulation of AR4-2J cell growth and survival.

Regulation and function of COX-2 gene expression in isolated gastric parietal cells.

We examined expression, function, and regulation of the cyclooxygenase (COX)-2 gene in gastric parietal cells. COX-2-specific mRNA was isolated from purified (>95%) canine gastric parietal cells in primary culture and measured by Northern blots using a human COX-2 cDNA probe. Carbachol was the most potent inducer of COX-2 gene expression.
