Rational government of patient fluxes from primary care to hepatology clinic is a priority of nonalcoholic fatty liver disease (NAFLD) research. Estimating pre-test probability of disease, risk of fibrosis progression, and exclusion of competing causes of liver disease must be addressed. Here we propose a novel taxonomic classification of NAFLD based on hepatic, pathogenic and systemic features of disease in the individual patient. The variable course of disease in any given patient remains a clinical enigma. Therefore, future studies will have to better characterize the role of genetic polymorphisms, family and personal history, diet, alcohol, physical activity and drugs as modifiers of the course of disease and clues to the early diagnosis of hepatocellular carcinoma. A better understanding of these, together with a taxonomic diagnosis, may prompt a more accurate personalization of care. For example, understanding the putative role of psycho-depression in NAFLD promises to revolutionize disease management in a proportion of cases. Similarly, sex differences in outcome and response to treatment are insufficiently characterized. More studies are awaited regarding those forms of NAFLD which occur secondary to endocrine derangements. The intersections between NAFLD and the lung must better be defined. These include the bi-directional associations of NAFLD and chronic obstructive pulmonary disease and sleep apnoea syndrome, as well as the totally unexplored chapter of NAFLD and coronavirus disease 2019 (COVID-19). Finally, the therapeutic roles of intermittent fasting and anticoagulation must be assessed. In conclusion, over the last 20 years, NAFLD has taught us a lot regarding the pathogenic importance of insulin resistance, the limitations of correcting this in the treatment of NAFLD, the root causes of diabetes and the metabolic syndrome, sex differences in disease and the role of nuclear receptors. However, the overwhelming COVID-19 pandemic is now expected to reset the priorities of public health.

: Nonalcoholic fatty liver disease (NAFLD) is a main cause of chronic liver disease in children. With the global obesity epidemic, the prevalence of NAFLD is increasing both in industrialized and developing countries. NAFLD is a multisystem disorder and a hepatic manifestation of the metabolic syndrome. Growing scientific evidence suggests that NAFLD is an independent risk factor for cardiovascular disease. This paper briefly describes the current knowledge concerning the association between NAFLD and cardiac dysfunction in children.

AbstractNonalcoholic fatty liver disease (NAFLD) denotes a condition with excess fat in the liver. The prevalence of NAFLD is increasing, averaging > 25% of the Western population. In 25% of the patients, NAFLD progresses to its more severe form: nonalcoholic steatohepatitis and >25% of these progress to cirrhosis following activation of inflammatory and fibrotic processes. NAFLD is associated with obesity, type 2 diabetes, and the metabolic syndrome and represents a considerable and increasing health burden. In the near future, NAFLD cirrhosis is expected to be the most common cause for liver transplantation. NAFLD patients have an increased risk of developing cardiovascular disease as well as liver-related morbidity. In addition, hepatic steatosis itself appears to represent an independent cardiovascular risk factor. In the present review, we provide an overview of the overlapping mechanisms and prevalence of NAFLD and cardiovascular disease.

Obesity And Diabetes

Nonalcoholic fatty liver disease (NAFLD) is a spectrum of chronic liver conditions that are characterized by steatosis, inflammation, fibrosis, and liver injury. The global prevalence of NAFLD is rapidly increasing in proportion to the rising incidence of obesity and type 2 diabetes. Because NAFLD is a multifaceted disorder with many underlying metabolic abnormalities, currently, there is no pharmacological agent that is therapeutically approved for the treatment of this disease. Folate is a water-soluble B vitamin that plays an essential role in one-carbon transfer reactions involved in nucleic acid biosynthesis, methylation reactions, and sulfur-containing amino acid metabolism. The liver is the primary organ responsible for storage and metabolism of folates. Low serum folate levels have been observed in patients with obesity and diabetes. It has been reported that a low level of endogenous folates in rodents perturbs folate-dependent one-carbon metabolism, and may be associated with development of metabolic diseases such as NAFLD. This review highlights the biological role of folate in the progression of NAFLD and its associated metabolic complications including obesity and type 2 diabetes. Understanding the role of folate in metabolic disease may position this vitamin as a potential therapeutic for NAFLD.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is a kind of chronic liver disease among general population. Recent years, more and more new experiments have made the role of ursodeoxycholic acid (UDCA) become clearer. In this meta-analysis, we analyzed the efficacy of ursodeoxycholic acid (UDCA) for the treatment of nonalcoholic fatty liver disease (NAFLD). Methods We searched the Web of Science, Pubmed, Embase and Cochrane library databases for relavent studies published before March 1, 2019. We examined 134 randomized controlled trials (RCTs) that investigated the effectiveness of UDCA in NAFLD against placebo or other treatments. Next, we conducted meta-analysis by Stata(version 12.0) to examine the change among several indices: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), Alkaline phosphatase (AP), total bilirubin and albumin. Results Following the application of different inclusion and exclusion criteria, 9 articles with 1106 participants were finally selected. The forest plot displayed that UDCA treatment can significantly decrease the ALT levels among the NAFLD patients (SMD=0.17,95%CI [0.03 to 0.3], P=0.07). However, UDCA treatment did not significantly affect the AST, GGT, AP, total bilirubin and albumin levels. Further, the subgroup analyses suggested the significant role of UDCA treatment in different geographical regions, age group and treatment duration (P=0.003 in people from Europe, P=0.001 in people older than 50 years and P=0.008 in longer duration(>6 months)). Conclusion In this study, several indices we analyzed among 9 articles. UDCA treatment was found beneficial in lowering the ALT levels in NAFLD patients. The remaining indices like AST, GGT, AP showed non-significant changes in this analysis. This could be attributed for the insufficient number of trials because all parameters were not analyzed in each individual RCT. Therefore, future meta-analysis will be required to fully confirm and validate the efficacy of UDCA in NAFL.
