Serum ferritin is a discriminant marker for both fibrosis and inflammation in histologically proven non-alcoholic fatty liver disease patients

2011

INTRODUCTION: Differentiation between steatosis and non-alcoholic steatohepatitis (NASH) in non-alcoholic fatty liver disease (NAFLD) is important as NASH progress to cirrhosis. No specific laboratory/imaging technique exists either to diagnose NASH or to select patients for liver biopsy. PATIENTS AND METHODS: We evaluated serum ferritin and the features of metabolic syndrome with respect to histological inflammation and/or fibrosis in NAFLD patients. The Kleiner scoring system was used to classify NAFLD in consecutive liver biopsies. One hundred and eleven patients: median age 52.6, 64 males, obesity 62, diabetes mellitus (DM) 58, arterial hypertension 26 and hyperlipidaemia 40%. RESULTS: …

Raised serum Interleukin-6 identifies patients with liver cirrhosis at high risk for overt hepatic encephalopathy

2019

BACKGROUND Systemic inflammation is a driving force for the development of hepatic encephalopathy and recent studies demonstrated that elevated Interleukin-6 (IL-6) serum levels are associated with the presence of minimal hepatic encephalopathy in patients with liver cirrhosis. AIM To test the hypothesis that IL-6 is a suitable marker to identify patients with liver cirrhosis at high risk for the development of overt hepatic encephalopathy. METHODS 201 patients were included into this prospective cohort study and were followed for a mean time of 322 days. Covert hepatic encephalopathy was diagnosed according to the West-Haven criteria (hepatic encephalopathy grade 1) and with the portosyste…

Digital Pathology Enables Automated and Quantitative Assessment of Inflammatory Activity in Patients with Chronic Liver Disease

2021

Traditional histological evaluation for grading liver disease severity is based on subjective and semi-quantitative scores. We examined the relationship between digital pathology analysis and corresponding scoring systems for the assessment of hepatic necroinflammatory activity. A prospective, multicenter study including 156 patients with chronic liver disease (74% nonalcoholic fatty liver disease-NAFLD, 26% chronic hepatitis-CH etiologies) was performed. Inflammation was graded according to the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network system and METAVIR score. Whole-slide digital image analysis based on quantitative (I-score: inflammation ratio) and morphometric (C-sco…

Clinical states of cirrhosis and competing risks.

2018

The clinical course of cirrhosis is mostly determined by the progressive increase of portal hypertension, hyperdynamic circulation, bacterial translocation and activation of systemic inflammation. Different disease states, encompassing compensated and decompensated cirrhosis and a late decompensated state, are related to the progression of these mechanisms and may be recognised by haemodynamic or clinical characteristics. While these disease states do not follow a predictable sequence, they correspond to varying mortality risk. Acute-on-chronic liver failure may occur either in decompensated or in compensated cirrhosis and is always associated with a high short-term mortality. The increasin…

Definite and indeterminate nonalcoholic steatohepatitis share similar clinical features and prognosis : A longitudinal study of 1893 biopsy-proven no…

2021

[Background and Aim] Histological score systems may not fully capture the essential nonalcoholic steatohepatitis (NASH) features, which is one of the leading causes of screening failure in clinical trials. We assessed the NASH distribution and its components across the fibrosis stages and their impact on the prognosis and their relationship with the concept of metabolic-associated fatty liver disease (MAFLD).

Phenolic Extract from Sonchus oleraceus L. Protects Diabetes-related Liver Injury in Rats through TLR4/NF-κB Signaling Pathway

2019

Sonchus oleraceus Linn. is of great interest in scientific platform because it exhibits significant biological activities. This study investigated the liver protective effects and mechanism of phenolic extract from S. oleraceus (SOL) on Streptozotocin (STZ)-induced diabetic rats. SOL significantly increased both superoxide dismutase activity and glutathione level, while causing a reduction of malondialdehyde level in the liver. Moreover, SOL ameliorates STZ-induced liver function and pathological damages. Diabetic rats fed with S. oleraceus daily for 6 weeks showed significantly decreased levels of tumor necrosis factor alpha and interleukin-1β in the liver. Sonchus oleraceus decreased the …

Can PBDEs affect the pathophysiologic complex of epithelium in lung diseases?

2020

Brominated flame-retardant (BFRs) exposure promotes multiple adverse health outcomes involved in oxidative stress, inflammation, and tissues damage. We investigated BFR effects, known as polybrominated diphenyl ethers (PBDEs) (47, 99 and 209) in an air-liquid-interface (ALI) airway tissue derived from A549 cell line, and compared with ALI culture of primary human bronchial epithelial cells (pHBEC). The cells, exposed to PBDEs (47, 99 and 209) (0.01-1 mu M) for 24 h, were studied for IL-8, Muc5AC and Muc5B (mRNAs and proteins) production, as well as NOX-4 (mRNA) expression. Furthermore, we evaluated tight junction (TJ) integrity by Trans-Epithelial Electrical Resistance (TEER) measurements, …

Mast cells and the development of allergic airway disease

2008

Murine models have highlighted the importance of T-cells and TH2 cytokines in development of allergen-induced airway disease. In contrast, the role of mast cells for the development of allergic airway disease has been controversial. Recent studies in murine models demonstrate a significant contribution of mast cells during the development of airway hyperresponsiveness and airway inflammation. Furthermore these models have allowed identifying certain mast cell-produced mediators (e.g. histamine and leukotriene B4) to be involved in the recruitment of effector T-cells into the lung. Additionally, mast cell-produced TNF can directly activate TH2 cells and contribute to the development of aller…

MARKERS OF INFLAMMATION AND RISK OF VASCULAR EVENTS IN PATIENTS WITH NON-INSULIN DEPENDANT DIABETES

2006

A follow-up study of a genome-wide association scan identifies a susceptibility locus for venous thrombosis on chromosome 6p24.1.

2010

International audience; To identify genetic susceptibility factors conferring increased risk of venous thrombosis (VT), we conducted a multistage study, following results of a previously published GWAS that failed to detect loci for developing VT. Using a collection of 5862 cases with VT and 7112 healthy controls, we identified the HIVEP1 locus on chromosome 6p24.1 as a susceptibility locus for VT. Indeed, the HIVEP1 rs169713C allele was associated with an increased risk for VT, with an odds ratio of 1.20 (95% confidence interval 1.13-1.27, p = 2.86 x 10(-9)). HIVEP1 codes for a protein that participates in the transcriptional regulation of inflammatory target genes by binding specific DNA …
