REVIEW
Harriet S Cheng, Marius Rademaker
Increasingly, existing evidence indicates that methotrexate-associated liver injury is related to comorbid risk factors such as diabetes, alcoholism, and obesity, rather than to methotrexate itself. Despite this fact, significant effort continues to be expended in the monitoring of low-dose methotrexate in patients with psoriasis. The gold standard investigation has been liver biopsy, but this is associated with significant morbidity and mortality. As methotrexate-induced liver injury is uncommon, the risk/benefit ratio of liver biopsy has been questioned...

A novel controlled attenuation parameter (CAP) using FibroScan® has been developed for assessment of liver steatosis. The aim was to evaluate the frequency and associated factors for moderate/severe steatosis evaluated by CAP in CHC patients submitted to transient elastography (TE) by FibroScan® . CHC patients underwent TE with CAP evaluation. The classification of steatosis was defined as: CAP < 222 dB/m = S0; CAP ≥ 222 dB/m and <233dB /m = S1; ≥233 dB/m <290dB/m = S2 and >= 290 dB/m = S3...

Liver stiffness (LS) as measured by transient elastography is increasingly used to non-invasively assess liver fibrosis. However, LS is efficiently modulated by confounders like arterial and portal pressure (PP). We here study the effect of acute hemodynamic changes on LS (measured by µFibroscan) in a rodent model of cirrhosis in response to pharmacological modulation of PP by losartan, NO-donors and propranolol. Additionally, changes of LS and the hepatic venous pressure gradient (HVPG) under propranolol therapy were assessed with regard to clinical outcomes in a human cohort of n=38 cirrhotic patients...

The polymorphisms at the α-chain of the IL-7 receptor (IL7RA) have been related to T-cell homeostasis and development and may contribute to immune system deregulation. In the present study, we analyzed the association between IL7RA polymorphisms and the progression of liver fibrosis in patients infected with HCV. We carried out a retrospective study with a design consisting of repeated measurements in 187 HCV-infected patients, to study the risk prediction of liver fibrosis progression using genetic factors...

BACKGROUND AND AIMS: Pruritus is one of the complications with chronic liver disease and markedly worsens quality of life. However, the current status of pruritus in chronic hepatitis C patients who have achieved a sustained virological response (SVR) has not been clarified sufficiently. The aim of this study was to investigate the predictors of pruritus in post-SVR patients treated with direct-acting antivirals (DAA). PATIENTS AND METHODS: In this retrospective study, we enrolled 110 hepatitis C patients with SVR who underwent serial shear wave elastography before DAA therapy and at the end of treatment...

Shear wave elastography methods are able to accurately measure tissue stiffness, allowing these techniques to monitor the progression of hepatic fibrosis. While many methods rely on acoustic radiation force to generate shear waves for 2-D imaging, probe oscillation shear wave elastography (PROSE) provides an alternative approach by generating shear waves through continuous vibration of the ultrasound probe while simultaneously detecting the resulting motion. The generated shear wave field in in vivo liver is complicated, and the amplitude and quality of these shear waves can be influenced by the placement of the vibrating probe...
