Hyperuricaemia: another metabolic feature affecting the severity of chronic hepatitis because of HCV infection.
2011
Background Several works observed a link between uric acid serum levels and clinical and histological features of nonalcoholic fatty liver disease. An association between chronic hepatitis C (CHC) and uric acid levels has been poorly investigated. Aims To assess the potential association between uric acid serum levels and both histological features of liver damage and sustained virological response (SVR) in a homogeneous cohort of CHC patients. Methods Consecutive biopsy-proven CHC patients were included. Hyperuricaemia was diagnosed with uric acid serum levels >7 mg/dl in men, and >6 mg/dl in women. Patients underwent therapy with pegylated interferon plus ribavirin. Results Hyperuricaemia…
Metabolic syndrome triggered by high-fructose diet favors choroidal neovascularization and impairs retinal light sensitivity in the rat
2014
Diabetic retinopathy and age-related macular degeneration are the leading causes of blindness in Western populations. Although it is a matter of controversy, large-scale population-based studies have reported increased prevalence of age-related macular degeneration in patients with diabetes or diabetic retinopathy. We hypothesized that metabolic syndrome, one of the major risk factors for type 2 diabetes, would represent a favorable environment for the development of choroidal neovascularization, the main complication of age-related macular degeneration. The fructose-fed rat was used as a model for metabolic syndrome in which choroidal neovascularization was induced by laser photocoagulatio…
Immunopositivity for histone macroH2A1 isoforms marks steatosisassociated hepatocellular carcinoma.
2012
BackgroundHepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Prevention and risk reduction are important and the identification of specific biomarkers for early diagnosis of HCC represents an active field of research. Increasing evidence indicates that fat accumulation in the liver, defined as hepatosteatosis, is an independent and strong risk factor for developing an HCC. MacroH2A1, a histone protein generally associated with the repressed regions of chromosomes, is involved in hepatic lipid metabolism and is present in two alternative spliced isoforms, macroH2A1.1 and macroH2A1.2. These isoforms have been shown to predict lung and colon cancer recurrence but to ou…
When GLP-1 hits the liver: a novel approach for insulin resistance and NASH
2012
nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum ranging from simple steatosis to steatohepatitis (NASH), increasing fibrosis and eventually, cirrhosis ([22][1]). Importantly, NASH accompanied by fibrosis and severe inflammation is the most relevant predictor for disease progression
Metabolic comorbidities and male sex influence steatosis in chronic hepatitis C after viral eradication by direct-acting antiviral therapy (DAAs): Ev…
2021
Background: Chronic hepatitis C (CHC) is associated with hepatic steatosis, related to both a direct viral action and metabolic features. Vice-versa data on hepatic steatosis after viral eradication by direct-acting antiviral agents (DAA) are undefined although the presence of metabolic alterations could strongly influence the occurrence of steatosis as in NAFLD. The controlled attenuation parameter (CAP) (FibroscanⓇ) allows the qualitative and quantitative evaluation of fatty liver. Aim: to evaluate in patients with CHC whether hepatic steatosis diagnosed by CAP modifies after DAAs-induced sustained virologic response (SVR). Methods: Data were collected the day of DAAs therapy starting and…
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 ...
Science to Practice: Should Biopsy Be Performed in Potential Liver Donors When Unenhanced CT Shows an Unacceptable Degree of Steatosis for Transplant…
2006
Park et al (1) have demonstrated that unenhanced CT can accurately depict moderate to severe (ie, ≥30%) macrovesicular steatosis, thereby allowing avoidance of biopsy in potential living liver donors who have an unacceptable degree of steatosis for transplantation. Biopsy will still be needed in donors with macrovesicular steatosis of less than 30% at unenhanced CT to rule out occult chronic liver disease and more severe steatosis that is undetected at CT. © RSNA, 2006.
Therapeutic effect of fractionated by ultrafiltration red beetroot (Beta vulgaris l.) juice in rats with food-induced fatty liver
2019
The prevalence of non-alcoholic fatty liver disease (NAFLD), being a component of metabolic syndrome, has increased (15-27%) in the industrialized world. The deep mechanism of this pathology is not clear, but it is multifactorial. There is a huge amount of food supplements and medicines with hepatoprotective effect on the market, but the NAFLD problem is far from being resolved. Hepatoprotective products have to provide wide spectra of biological effects, including antioxidant, hypolipidemic, anti-inflammatory action. It is peculiar to natural compounds, including red beetroot juice, which is well known to most of the population. This is important in view of the high prevalence of NAFLD. Th…
