Fatty liver in familial hypobetalipoproteinemia: triglyceride assembly into VLDL particles is affected by the extent of hepatic steatosis
2003
Familial hypobetalipoproteinemia (FHBL) subjects may develop fatty liver. Liver fat was assessed in 21 FHBL with six different apolipoprotein B (apoB) truncations (apoB-4 to apoB-89) and 14 controls by magnetic resonance spectroscopy (MRS). Liver fat percentages were 16.7 +/- 11.5 and 3.3 +/- 2.9 (mean +/- SD) (P = 0.001). Liver fat percentage was positively correlated with body mass index, waist circumference, and areas under the insulin curves of 2 h glucose tolerance tests, suggesting that obesity may affect the severity of liver fat accumulation in both groups. Despite 5-fold differences in liver fat percentage, mean values for obesity and insulin indexes were similar. Thus, for similar…
Reactive hyperemia index (RHI) and cognitive performance indexes are associated with histologic markers of liver disease in subjects with non-alcohol…
2017
BACKGROUND: No study evaluated vascular health markers in subjects with non-alcoholic fatty liver disease (NAFLD) through a combined analysis of reactive hyperemia peripheral arterial tonometry (RH-PAT) and arterial stiffness indexes. AIM OF THE STUDY: We aimed to assess whether NAFLD and its histological severity are associated with impairment of arterial stiffness and RH-PAT indexes in a mixed cohort of patients with biopsy-proven NAFLD. MATERIALS AND METHODS: The Kleiner classification was used to grade NAFLD grade. Pulse wave velocity (PWV) and augmentation index (Aix) were used as markers of arterial stiffness, whereas endothelial function was assessed using reactive hyperemia index (R…
Paraoxonase-1 deficiency is associated with severe liver steatosis in mice fed a high-fat high-cholesterol diet: a metabolomic approach.
2013
Oxidative stress is a determinant of liver steatosis and the progression to more severe forms of disease. The present study investigated the effect of paraoxonase-1 (PON1) deficiency on histological alterations and hepatic metabolism in mice fed a high-fat high-cholesterol diet. We performed nontargeted metabolomics on liver tissues from 8 male PON1-deficient mice and 8 wild-type animals fed a high-fat, high-cholesterol diet for 22 weeks. We also measured 8-oxo-20-deoxyguanosine, reduced and oxidized glutathione, malondialdehyde, 8-isoprostanes and protein carbonyl concentrations. Results indicated lipid droplets in 14.5% of the hepatocytes of wild-type mice and in 83.3% of the PON1-deficie…
A Sequential Algorithm Combining ADAPT and Liver Stiffness Can Stage Metabolic-Associated Fatty Liver Disease in Hospital-Based and Primary Care Pati…
2020
INTRODUCTION Metabolic-associated fatty liver disease is common, with fibrosis the major determinant of adverse outcomes. Population-based screening tools with high diagnostic accuracy for the staging of fibrosis are lacking. METHODS Three independent cohorts, 2 with both liver biopsy and liver stiffness measurements (LSMs, n = 254 and 65) and a population sample (n = 713), were studied. The performance of a recently developed noninvasive algorithm (ADAPT [age, diabetes, PRO-C3 and platelets panel]) as well as aspartate aminotransferase-to-platelet ratio index, fibrosis-4, nonalcoholic fatty liver disease fibrosis score, and LSM was used to stage patients for significant (≥F2) and advanced …
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
Non-alcoholic fatty liver disease increases the risk of incident chronic kidney disease
2020
BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease. Its role in the development of extrahepatic co-morbidities is under investigation. The impact of NAFLD on the development of chronic kidney disease (CKD) is incompletely understood. The aim of this study was to explore the potential contribution of NAFLD on CKD in Germany. METHODS: The Disease Analyzer Database covering 7.49 million cases in Germany was explored for patients diagnosed with NAFLD between 2000 and 2015 and was matched 1:1 to a cohort without NAFLD. Matching criteria included age, sex, physician, index year and co-diagnoses associated with CKD. The primary outcomes of thi…
Increased erythrocytes n-3 and n-6 polyunsaturated fatty acids is significantly associated with a lower prevalence of steatosis in patients with type…
2011
Summary Background & aims Non-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome and type 2 diabetes. Although dietary fat contributes substantially to the accumulation of liver fat, the role of individual fatty acids in this accumulation is unclear. Objective In this study, we set out to determine whether liver fat content (LFC), was associated with red blood cell fatty acid (RBC-FA) composition in people with type 2 diabetes. Design, settings, and participants One hundred and sixty-two type 2 diabetic patients were included in this study. LFC was measured using 1H-MR Spectroscopy. RBC-FA composition was measured by gas chromatography. Results One…
Epicardial fat in patients with non-alcoholic fatty liver disease
2015
To the Editor: We recently reported that epicardial fat thickness is significantly associated with the severity of liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD), and that in this clinical setting, morphological and functional cardiac alterations by echocardiography are inversely related with the severity of liver damage [1]. Of note, these associations were maintained after correction for both cardiometabolic and hepatic confounders including visceral adiposity. In their letter [10], Corrao and colleagues suggest that some cytokines/adipocytokines as well as adiponectin, transforming growth factor b1, e-selectin, endothelin, and fibroblast growth factor 21 could e…
Insulin-Like Growth Factor-I, Inflammatory Proteins, and Fibrosis in Subjects With Nonalcoholic Fatty Liver Disease
2013
Inflammation may have a pathogenic role in the progression of nonalcoholic fatty liver disease (NAFLD); by contrast, the role of anti-inflammatory molecules has not been addressed. Low circulating levels of the anti-inflammatory molecule IGF-I have been described in subjects with NAFLD.The aim of the study was to elucidate the clinical significance of IGF-I in NAFLD and its relationship with inflammatory biomarkers and fibrosis.We conducted a cross-sectional study and in vitro experiments on hepatic HepG2 cells at the Internal Medicine and Gastrointestinal and Liver Units of the Universities of Catanzaro and Palermo.A total of 221 individuals with NAFLD diagnosed on ultrasonography (cohort …
