Chemotherapy and Hepatic Steatosis: Impact on Postoperative Morbidity and Survival after Liver Resection for Colorectal Liver Metastases

2020

<b><i>Background:</i></b> Hepatic steatosis and chemotherapy in the treatment of colorectal liver metastases (CLM) are often linked to increased mortality and morbidity after liver resection. This study evaluates the influence of macrovesicular hepatic steatosis and chemotherapeutic regimes on graded morbidity and mortality after liver resection for CLM. <b><i>Methods:</i></b> A total of 323 cases of liver resection for CLM were retrospectively analysed using univariable and multivariable linear, ordinal and Cox regression analyses. The resected liver tissue was re-evaluated by a single observer to determine the grade and type of hepatic steat…

Cytometric analysis for drug-induced steatosis in HepG2 cells

2009

Drugs are capable of inducing hepatic lipid accumulation. When fat accumulates, lipids are primarily stored as triglycerides which results in steatosis and provides substrates for lipid peroxidation. An in vitro multiparametric flow cytometry assay was performed in HepG2 cells by using fluorescent probes to analyze cell viability (propidium iodide, PI), lipid accumulation (BODIPY493/503), mitochondrial membrane potential (tetramethyl rhodamine methyl ester, TMRM) and reactive oxygen species generation (ROS) (2',7'-dihydrochlorofluorescein diacetate, DHCF-DA) as functional markers. All the measurements were restricted to live cells by gating the cells that excluded PI or those that exhibited…

A mouse model of alcoholic liver disease reveals protection by Lactobacillus fermentum

2017

The knowledge and treatment of alcoholic liver disease is still plagued with gaps mostly due to the inherent limitations of research with patients. We developed an animal model for studying liver histopathology, Hsp-chaperones involvement, and response to treatment. The system was standardized using mice to which ethanol was orally administered alone or in combination with Lactobacillus fermentum for 4, 8 and 12 weeks and applying a battery of techniques (histology, immunohistochemistry, Western blotting, real-time PCR, immunoprecipitation, 3-nitrotyrosine labeling) to assess liver pathology and Hsp60, iNOS gene expression and protein levels, and Hsp60 post-translational modifications. Stea…

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 …

Effect of aerobic exercise and diet on liver fat in pre-diabetic patients with non-alcoholic-fatty-liver-disease: A randomized controlled trial.

2017

AbstractThe study aimed to assess whether aerobic exercise (AEx) training and a fibre-enriched diet can reduce hepatic fat content (HFC) and increase glycaemic control in pre-diabetic patients with non-alcoholic fatty liver disease (NAFLD). Six-hundred-and-three patients from seven clinics in Yangpu district, Shanghai, China were recruited. Of them 115 individuals aged 50–65-year fulfilled the inclusion criteria (NAFLD with impaired fasting glucose or impaired glucose tolerance) and were randomly assigned into exercise (AEx n = 29), diet (Diet n = 28), exercise plus diet (AED n = 29), or no-intervention (NI n = 29) groups. Progressive supervised AEx training (60–75% VO2max intensity) was gi…

Non-invasive assessment of liver steatosis and fibrosis in HIV/HCV- and HCV- infected patients

2013

BACKGROUND: Conflicting data have been reported on the prevalence of liver steatosis, its risk factors and its relationship with fibrosis in patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection or with HCV mono-infection. AIM: The study aims were to assess steatosis prevalence and its risk factors in both HCV groups. We also evaluated whether steatosis was linked with advanced fibrosis. Sixty-eight HIV/HCV co-infected and 69 HCV mono-infected patients were consecutively enrolled. They underwent liver ultrasonography and transient elastography. Bright liver echo-pattern was used to diagnose steatosis; advanced fibrosis was defined as liver stiffness ≥ 9.5 kPa…

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…

Metabolic Factors and Chronic Hepatitis C: A Complex Interplay

2013

In the last years, several lines of evidence showed how metabolic factors may influence the natural history of patients with chronic hepatitis C. Chronic HCV infection is able to perturb the metabolic homeostasis of the host, in a context of complex interactions where pre-existent metabolic status and genetic background play an important role, allowing us to state that HCV infection is a systemic disease. In this review, we discuss the most recent lines of evidence on the main metabolic factors that are known to be associated with CHC, namely, insulin resistance/type 2 diabetes, steatosis, visceral obesity, atherosclerosis, vitamin D, menopause, fructose and coffee intake, lipoproteins, met…
