Background: Hepatic steatosis is a public health problem with increased incidence and prevalence OBJECTIVE: To determine whether the liver steatosis, as measured by the Fatty Liver Index (FLI), is related to metabolic risk and vascular factors and, if so, to identify the clinical-metabolic factor that explains the higher vascular risk., Methods: Cross-sectional study including a sample of 531 men who came to the University of Navarra Clinic Check-up Unit. The degree of steatosis was determined by the FLI. The metabolic risk was assessed using a scale based on determinations of HDL, LDL, triglycerides, blood glucose, HOMA-IR, neutrophil/lymphocyte index, and systolic blood pressure. The vascular risk was assessed by the presence of carotid and/or femoral atheromatous plaques. The dose-response association between FLI and both risks was analysed using non-parametric models (splines) and logistic regression., Results: The sample studied had a mean age of 52.70years, with 49.3% having an FLI ≥60, as well as 33.6% with metabolic syndrome, and 43.9% with carotid and/or femoral atheromatous plaques. The relationship between FLI and metabolic risk and vascular was linear (metabolic: non-linear P=.097; linear P<.001; vascular: non-linear P=1.000; linear P=.028). For every 10 units of increase in FLI, the odds of presenting with atheroma plaques increased by 9.7% (OR=1.097; 95% confidence interval 1.010-1.191). When adjusting for triglyceridaemia, the association disappeared (OR=1.001)., Conclusions: Patients with fatty liver disease had an increased metabolic and vascular risk. The increased vascular risk is associated with the triglyceride level. On a clinical level, this study suggests that these patients could benefit from treatment of hypertriglyceridaemia., (Copyright © 2020 Sociedad Española de Arteriosclerosis.

Background: Non-alcoholic fatty liver disease (NAFLD), a condition that leads to fibrosis, is caused by intake of very high-fat diets (HFDs). However, while the negative impact on the liver of these diets has been an issue of interest, systematic research on the effect of HFDs are lacking., Objective: To characterize the overall impact of HFDs on both molecular and morphological signs of liver remodeling., Methods: A study was conducted on male C57BL/6J mice to assess the effect of 4- and 8-week HFDs (60% kcal from fat) on (i) liver steatosis and fibrosis, and (ii) expression of factors involved in inflammation and angiogenesis., Results: After an 8-week HFD, vascular endothelial growth factor type-2 receptor (VEGF-R2) and fatty acid translocase/trombospondin-1 receptor (CD36) were overexpressed in liver tissue of mice given HFDs. These changes suggest impaired liver angiogenesis and occurred together with (i) increased GPR78-BiP and EIF2α phosphorylation, suggesting endoplasmic reticulum stress, (ii) induction of Col1a1 gene expression, a marker of fibrosis, and (iii) increased CD31 immunolabeling, consistent with active angiogenesis and fibrosis., Conclusion: Our data show that very HFDs promote a rapid inflammatory response, as well as deregulation of angiogenesis, both consistent with development of liver fibrosis., (Copyright © 2019 SEEN y SED.

Objective: Non-alcoholic fatty liver is a chronic liver disease in which fat is deposited in the liver, causing an inflammation called non-alcoholic steatohepatitis (NASH), and fibrosis. NASH is associated with metabolic syndrome (MS) and other cardiovascular risk factors. The aim of this study was to analyse the epidemiological features of NASH within a hypertensive population, with a high prevalence of MS, and to determine the features related to NASH., Methods: The computerised records were collected from 3,473 patients from Mostoles University Hospital's Hypertension Unit in order to perform a retrospective, cross-sectional study. NASH was considered as ultrasound-detected fatty liver disease along with serum levels of alanine aminotransferase or aspartate aminotransferase 1.5 times above normal values, having ruled out other causes of liver disease: alcohol abuse, autoimmune hepatitis, drug toxicity, virus and hemochromatosis. A univariate, multivariate, and ANOVA analysis were performed to assess the effect of the studied features on the response of interest., Results: The cohort included 2,242 patients (51.3% men). NASH was present in 255 patients (11.4%) of whom 71% were men. MS was detected in 52.6% of patients (69.4% in the NASH group, and 50.5% in the non-NASH group, P=.001). Prevalence of type 2 diabetes mellitus was 11.5% (16.5% in the NASH group, and 10.8% in the non-NASH group, P=.01). In a multivariate analysis, waist circumference, MS, body mass index, type 2 diabetes mellitus, age, fasting serum insulin, and serum ferritin were associated with NASH. ANOVA revealed that NASH and transaminases were also significantly associated with components of metabolic syndrome., Conclusions: In the population studied, MS, type 2 diabetes mellitus, and several components of MS were independently associated with NASH. Therefore, NASH can be considered as the liver manifestation of MS in patients with arterial hypertension., (Copyright © 2018 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction and Aims: Nonalcoholic fatty liver disease has now become a worldwide health problem, and its dramatic increase is due to the prevalence of diseases such as obesity, type 2 diabetes mellitus, and metabolic syndrome. The aim of our study was to publish the current prevalence of hepatic steatosis in a Mexican population undergoing routine medical check-up, as well as to analyze its relation to BMI, liver function tests, and lipid profile., Materials and Methods: An observational, retrospective, cross-sectional study was conducted on patients that underwent medical check-up within the time frame of January 2011 and December 2015 at the Hospital San Javier. Patients included in the study were those with somatometry measurements (BMI), lipid profile, liver function tests, and abdominal ultrasound with a multi-frequency convex transducer., Results: We found that 65% of the patients presented with overweight or obesity and there was a 49.19% prevalence of hepatic steatosis in the study population. That prevalence was more frequent in men and hepatic steatosis was strongly linked to an increase in triglycerides, AST, and GGT and a decrease in HDL., Conclusions: Establishing the technical aspects of the study was an important aid to having better correlation with and standardization of the accepted definitions, given that ultrasound is an adequate screening technique for an open population. Our results clearly showed a direct relation between hepatic steatosis and alterations in BMI, triglycerides, HDL, ALT, and GGT., (Copyright © 2018. Publicado por Masson Doyma México S.A.)

Nonalcoholic fatty liver disease (NAFLD) affects nearly one third of the population worldwide. Mexico is one of the countries whose population has several risk factors for the disease and its prevalence could surpass 50%. If immediate action is not taken to counteract what is now considered a national health problem, the medium-term panorama will be very bleak. This serious situation prompted the Asociación Mexicana de Gastroenterología and the Asociación Mexicana de Hepatología to produce the Mexican Consensus on Fatty Liver Disease. It is an up-to-date and detailed review of the epidemiology, pathophysiology, clinical forms, diagnosis, and treatment of the disease, whose aim is to provide the Mexican physician with a useful tool for the prevention and management of nonalcoholic fatty liver disease., (Copyright © 2019 Asociación Mexicana de Gastroenterología.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver condition in the West. The prevalence and severity of NAFLD is higher and the prognosis worse in patients with psoriasis. The pathogenic link between psoriasis and NAFLD is chronic inflammation and peripheral insulin resistance, a common finding in diseases associated with psoriasis. NAFLD should therefore be ruled out during the initial evaluation of patients with psoriasis, in particular if they show signs of metabolic syndrome and require systemic treatment. Concomitant psoriasis and NAFLD and the likelihood of synergy between them place limitations on general recommendations and treatment for these patients given the potential for liver toxicity. As hepatotoxic risk is associated with some of the conventional drugs used in this setting (e.g., acitretin, methotrexate, and ciclosporin), patients prescribed these treatments should be monitored as appropriate. Anti-tumor necrosis factor agents hold the promise of potential benefits based on their effects on the inflammatory process and improving peripheral insulin resistance. However, cases of liver toxicity have also been reported in relation to these biologics. No evidence has emerged to suggest that anti-p40 or anti-interleukin 17 agents provide benefits or have adverse effects., (Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U.

Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the association of NAFLD with cardiovascular disease., (Copyright © 2016 Sociedad Española de Arteriosclerosis.

In this review we show you all the advances in ethiology, epidemiology, phisiopatology, natural history, clinic aspects, treatment and complications of non alcoholic steatohepatitis.

Non-alcoholic fatty liver disease (NAFLD) has become the most common liver disease in developed countries, covering a spectrum of pathological conditions ranging from single steatosis to non-alcoholic steatohepatitis, cirrhosis and hepatocellular carcinoma. Its pathogenesis has been often interpreted by the "double-hit" hypothesis, where the lipid accumulation in the liver is followed by proinflammatory mediators inducing inflammation, hepatocellular injury and fibrosis. Nowadays, a more complex model suggests that free fatty acids and their metabolites could be the true lipotoxic agents that contribute to the development of NAFLD and hepatic insulin resistance, suggesting a central role for metabolic lipases in that process., (Copyright © 2015 Sociedad Española de Arteriosclerosis.
