Association of liver steatosis with lipid oversecretion and hypotriglyceridaemia in C57BL/6j mice fed trans-10, cis-12-linoleic acid
2003
AbstractConjugated linoleic acids (CLA) have recently been recognized to reduce body fat and plasma lipids in some animals. This study demonstrated that the steatosis accompanying the fat loss induced by trans-10,cis-12-C18:2 (CLA2) and not cis-9,trans-11-C18:2 (CLA1) isomer in C57BL/6j mice was not due to an alteration of the liver lipoprotein production that was even increased. The 3-fold decrease in plasma triacylglycerol contents and the induction of mRNA expression of low-density lipoprotein receptors concomitantly observed in CLA2-fed mice suggested an increase in the lipoprotein clearance at the level of the liver itself. CLA1 feeding produced similar but attenuated effects on trigly…
Impact of liver steatosis on the antiviral response in the hepatitis C virus-associated chronic hepatitis.
2006
: Background/Aim: Liver steatosis (LS) has been variably associated with chronic hepatitis C (CHC) but whether it affects sustained virological response to antiviral treatment and by what mechanisms is a question still under debate, at least for some genotypes. The aim of this work was to assess the frequency of LS, its relationship with host and viral factors and to what extent it can influence the response to antiviral combination therapy with pegylated interferon (INF)+ribavirin in a group of patients with CHC from a single center. Patients: One hundred and twelve patients with histologically proven CHC were treated with Peg INF-α 2a 180 μg a week subcutaneously for 48 weeks plus ribavir…
Upregulation of liver VLDL receptor and FAT/CD36 expressions in LDLR-/- apoB100/100 mice fed trans-10,cis-12 conjugated linoleic acid
2006
International audience; This study explores the mechanisms responsible for the fatty liver setup in mice fed trans-10,cis-12 conjugated linoleic acid (t10c12 CLA), hypothesizing that an induction of low density lipoprotein receptor (LDLR) expression is associated with lipid accumulation. To this end, the effects of t10c12 CLA treatment on lipid parameters, serum lipoproteins, and expression of liver lipid receptors were measured in LDLR(-/-) apoB(100/100) mice as a model of human familial hypercholesterolemia itself depleted of LDLR. Mice were fed t10c12 CLA over 2 or 4 weeks. We first observed that the treatment induced liver steatosis, even in the absence of LDLR. Mice treated for 2 weeks…

Esteatosis hepática en la hepatitis crónica por virus C: estudio de los factores de riesgo y relación con el estadio de fibrosis
2009
Fundamento y objetivo La esteatosis hepatica (EH) es un hallazgo histologico frecuente en la infeccion cronica por el virus de la hepatitis C (VHC) que puede influir en el pronostico de la enfermedad. El objetivo del presente estudio prospectivo es valorar los factores asociados a su presencia y su relacion con el estadio de fibrosis en pacientes con infeccion cronica por VHC. Material y metodo Se incluyo a 84 pacientes consecutivos con ARN-VHC positivo, no tratados previamente y a los que se practico una biopsia hepatica. En todos los pacientes se recogieron en el momento de la biopsia variables demograficas, clinicas, analiticas, virales e histologicas. Se practicaron analisis bivariante …
Liver Steatosis and Fibrosis in OSA patients After Long-term CPAP Treatment: A Preliminary Ultrasound Study.
2015
In cases of morbid obesity, obstructive sleep apnea (OSA) was associated with biopsy-proven liver damage. The role of non-invasive techniques to monitor liver changes during OSA treatment with continuous positive airway pressure (CPAP) is unknown. We used non-invasive ultrasound techniques to assess liver steatosis and fibrosis in severe OSA patients at diagnosis and during long-term CPAP treatment. Fifteen consecutive patients with severe OSA (apnea hypopnea index 52.5 ± 19.1/h) were studied by liver ultrasound and elastography (Fibroscan) at 6-mo (n = 3) or 1-y (n = 12) follow-up. Mean age was 49.3 ± 11.9 y, body mass index (BMI) was 35.4 ± 6.4 kg/m(2). Adherence to CPAP was ≥5 h/night. A…
Liver eosinophilic infiltrate is a significant finding in patients with chronic hepatitis C.
2008
Eosinophilic infiltrate of liver tissue is described in primary cholestatic diseases, hepatic allograft rejection and drug-induced liver injury, but its significance and its implications in chronic hepatitis C are unknown. The aim of this study was to investigate the clinical significance of eosinophilic liver infiltrate in patients with chronic hepatitis C. We retrospectively evaluated 147 patients with chronic hepatitis C. The presence of eosinophilic infiltrate was investigated in liver biopsies, and a numeric count of eosinophilic leucocytes in every portal tract was assessed. An eosinophilic infiltrate of liver tissue (> or =3 cells evaluated in the portal / periportal spaces) was obse…
MRI as the new reference standard in quantifying liver steatosis: the need for international guidelines.
2012
We read with great interest the paper by Raptis et al 1 regarding the quantification of liver steatosis by chemical-shift MRI. Chemical-shift imaging takes advantage of the difference in resonance frequency between water and fat (more precisely methylene, the most abundant group in triglycerides) to differentiate them. The dual-echo (in-phase/out-of-phase) MR technique used by the authors and derived from one of their previously published papers2 neglects T2* decay and assumes that the signal difference is due to fat–water interference alone.3 Yet, liver iron …
Clinical and biochemical determinants of the extent of liver steatosis in type 2 diabetes mellitus
2015
Objective Nonalcoholic fatty liver disease is very frequent in both type 2 diabetes mellitus (T2DM) and the metabolic syndrome (MS), which share clinical and metabolic characteristics. Whether and to which extent these characteristics can predict the degree of liver steatosis are not entirely clear. Patients and methods We determined liver fat (divided into four classes) by standard sonographic images, and clinical and biochemical variables, in 60 consecutive patients with T2DM and with features of the MS. We examined both simple and multiple correlations between the degree of liver steatosis and the variables measured. Results Increased liver fat (defined as >5% of liver mass) was detec…
Chronic hepatitis C infection and insulin resistance: two best friends.
2011
Approximately 170 million people worldwide are chronically infected by HCV, which can result in progressive hepatic injury and fibrosis, culminating in cirrhosis and end-stage liver disease. Among ...
