BACKGROUND The severity of nonalcoholic fatty liver disease(NAFLD)and lipid metabolism are related to the occurrence of colorectal polyps.Liver-controlled attenuation parameters(liver-CAPs)have been established to predict the prognosis of hepatic steatosis patients.AIM To explore the risk factors associated with colorectal polyps in patients with NAFLD by analyzing liver-CAPs and establishing a diagnostic model.METHODS Patients who were diagnosed with colorectal polyps in the Department of Gastroenterology of our hospital between June 2021 and April 2022 composed the case group,and those with no important abnormalities composed the control group.The area under the receiver operating characteristic curve was used to predict the diagnostic efficiency.Differences were considered statistically significant when P<0.05.RESULTS The median triglyceride(TG)and liver-CAP in the case group were significantly greater than those in the control group(mmol/L,1.74 vs 1.05;dB/m,282 vs 254,P<0.05).TG and liver-CAP were found to be independent risk factors for colorectal polyps,with ORs of 2.338(95%CI:1.154–4.733)and 1.019(95%CI:1.006–1.033),respectively(P<0.05).And there was no difference in the diagnostic efficacy between liver-CAP and TG combined with liver-CAP(TG+CAP)(P>0.05).When the liver-CAP was greater than 291 dB/m,colorectal polyps were more likely to occur.CONCLUSION The levels of TG and liver-CAP in patients with colorectal polyps are significantly greater than those patients without polyps.Liver-CAP alone can be used to diagnose NAFLD with colorectal polyps. 展开更多

BACKGROUND Several bibliometric analyses have been carried out to identify research hotspots and trends in nonalcoholic fatty liver disease(NAFLD)research.Nonetheless,there are still significant knowledge gaps that must be filled to advance our understanding of and ability to treat NAFLD.AIM To evaluate,through bibliometric and visual analysis,the current status of related research,related research frontiers,and the developmental trends in the field of diet and NAFLD.METHODS We retrieved publications about diet and NAFLD published between 1987 and 2022 from Scopus.Next,we used VOSviewer 1.6.20 to perform bibliometric analysis and visualization.RESULTS We found a total of 1905 studies,including 1637(85.93%)original articles and 195(10.24%)reviews,focused on the examination of NAFLD and its correlation with diet that were published between 1987 and 2022.Among the remaining five types of documents,38 were letters,notes,editorials,meeting minutes,or brief surveys,representing 1.99%of the total documents.The countries with the most publications on this topic were China(n=539;28.29%),followed by the United States(n=379;19.90%),Japan(n=133;6.98%),and South Korea(n=127;6.6%).According to the citation analysis,the retrieved papers were cited an average of 32.3 times and had an h-index of 106,with 61014 total citations.The two main clusters on the map included those related to:(1)Inflammation and oxidative stress;and(2)Dietary interventions for NAFLD.CONCLUSION This was the first study to use data taken from Scopus to visualize network mapping in a novel bibliometric analysis of studies focused on diet and NAFLD.After 2017,the two domains that received the most attention were“dietary interventions for NAFL”’and“‘inflammation and oxidative stress implicated in NAFLD and its correlation with diet.”We believe that this study provides important information for academics,dietitians,and doctors,and that additional research on dietary interventions and NAFLD is warranted. 展开更多

Background:Nonalcoholic fatty liver disease(NAFLD)is associated with disordered lipid and iron metabolism.Our previous study has substantiated the pivotal role of Caveolin-1(Cav-1)in protecting hepatocytes and mediating iron metabolism in the liver.This study aimed to explore the specific mechanisms underlying the regulation of iron metabolism by Cav-1 in NAFLD.Methods:Hepatocyte-specific Cav-1 overexpression mice and knockout mice were used in this study.Cav-1-knockdown of RAW264.7 cells and mouse primary hepatocytes were performed to verify the changes in vitro.Moreover,a high-fat diet and palmitic acid plus oleic acid treatment were utilized to construct a NAFLD model in vivo and in vitro,respectively,while a high-iron diet was used to construct an in vivo iron overload model.Besides,iron concentration,the expression of Cav-1 and iron metabolism-related proteins in liver tissue or serum were detected using iron assay kit,Prussian blue staining,Western blotting,immunofluorescence staining,immunohistochemical staining and ELISA.The related indicators of lipid metabolism and oxidative stress were evaluated by the corresponding reagent kit and staining.Results:Significant disorder of lipid and iron metabolism occurred in NAFLD.The expression of Cav-1 was decreased in NAFLD hepatocytes(P<0.05),accompanied by iron metabolism disorder.Cav-1 enhanced the iron storage capacity of hepatocytes by activating the ferritin light chain/ferritin heavy chain pathway in NAFLD,subsequently alleviating the oxidative stress induced by excess ferrous ions in the liver.Further,CD68^(+) CD163^(+) macrophages expressing Cav-1 were found to accelerate iron accumulation in the liver,which was contrary to the effect of Cav-1 in hepatocytes.Positive correlations were also observed between the serum Cav-1 concentration and the serum iron-related protein levels in NAFLD patients and healthy volunteers(P<0.05).Conclusions:These findings confirm that Cav-1 is an essential target protein that regulates iron and lipid metabolic homeostasis.It is a pivotal molecule for predicting and protecting against the development of NAFLD. 展开更多

Background:Nonalcoholic fatty liver disease(NAFLD)is associated with impaired renal function,and both diseases often occur alongside other metabolic disorders.However,the prevalence and risk factors for impaired renal function in patients with NAFLD remain unclear.The objective of this study was to identify the prevalence and risk factors for renal impairment in NAFLD patients.Methods:All adults aged 18-70 years with ultrasound-diagnosed NAFLD and transient elastography examination from eight Asian centers were enrolled in this prospective study.Liver fibrosis and cirrhosis were assessed by FibroScan-aspartate aminotransferase(FAST),Agile 3+and Agile 4 scores.Impaired renal function and chronic kidney disease(CKD)were defined by an estimated glomerular filtration rate(eGFR)with value of<90 mL/min/1.73 m^(2) and<60 mL/min/1.73 m^(2),respectively,as estimated by the CKD-Epidemiology Collaboration(CKD-EPI)equation.Results:Among 529 included NAFLD patients,the prevalence rates of impaired renal function and CKD were 37.4%and 4.9%,respectively.In multivariate analysis,a moderate-high risk of advanced liver fibrosis and cirrhosis according to Agile 3+and Agile 4 scores were independent risk factors for CKD(P<0.05).Furthermore,increased fasting plasma glucose(FPG)and blood pressure were significantly associated with impaired renal function after controlling for the other components of metabolic syndrome(P<0.05).Compared with patients with normoglycemia,those with prediabetes[FPG≥5.6 mmol/L or hemoglobin A1c(HbA1c)≥5.7%]were more likely to have impaired renal function(P<0.05).Conclusions:Agile 3+and Agile 4 are reliable for identifying NAFLD patients with high risk of CKD.Early glycemic control in the prediabetic stage might have a potential renoprotective role in these patients. 展开更多

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is one of the most common chronic liver diseases in children and adolescents.NAFLD ranges in severity from isolated hepatic steatosis to nonalcoholic steatohepatitis(NASH),wherein hepatocellular inflammation and/or fibrosis coexist with steatosis.Circulating microRNA(miRNA)levels have been suggested to be altered in NAFLD,but the extent to which miRNA are related to NAFLD features remains unknown.This analysis tested the hypothesis that plasma miRNAs are significantly associated with histological features of NAFLD in adolescents.AIM To investigate the relationship between plasma miRNA expression and NAFLD features among adolescents with NAFLD.METHODS This study included 81 adolescents diagnosed with NAFLD and 54 adolescents without NAFLD from the Teen-Longitudinal Assessment of Bariatric Surgery study.Intra-operative core liver biopsies were collected from participants and used to characterize histological features of NAFLD.Plasma samples were collected during surgery for miRNA profiling.A total of 843 plasma miRNAs were profiled using the HTG EdgeSeq platform.We examined associations of plasma miRNAs and NAFLD features using logistic regression after adjusting for age,sex,race,and other key covariates.Ingenuity Pathways Analysis was used to identify biological functions of miRNAs that were associated with multiple histological features of NAFLD.RESULTS We identified 16 upregulated plasma miRNAs,including miR-193a-5p and miR-193b-5p,and 22 downregulated plasma miRNAs,including miR-1282 and miR-6734-5p,in adolescents with NAFLD.Moreover,52,16,15,and 9 plasma miRNAs were associated with NASH,fibrosis,ballooning degeneration,and lobular inflammation,respectively.Collectively,16 miRNAs were associated with two or more histological features of NAFLD.Among those miRNAs,miR-411-5p was downregulated in NASH,ballooning,and fibrosis,while miR-122-5p,miR-1343-5p,miR-193a-5p,miR-193b-5p,and miR-7845-5p were consistently and positively associated with all histological features of NAFLD.Pathway analysis revealed that most common pathways of miRNAs associated with multiple NAFLD features have been associated with tumor progression,while we also identified linkages between miR-122-5p and hepatitis C virus and between miR-199b-5p and chronic hepatitis B.CONCLUSION Plasma miRNAs were associated with NAFLD features in adolescent with severe obesity.Larger studies with more heterogeneous NAFLD phenotypes are needed to evaluate miRNAs as potential biomarkers of NAFLD. 展开更多

This editorial builds on the article titled“Establishment and validation of an adherence prediction system for lifestyle interventions in non-alcoholic fatty liver disease”by Zeng et al.We carried out a critical examination of nonalcoholic fatty liver disease(NAFLD)pathogenesis and how lifestyle interventions could facilitate disease resolution,particularly highlighting that non-alcoholic steatohepatitis(NASH)is a severe form of NAFLD.Our discussion details that weight loss is a pivotal factor in disease outcomes:A 3%-5%reduction is enough for resolution in 50%of non-obese individuals,while a 7%-10%reduction achieves similar benefits in obese individuals,as demonstrated by magnetic resonance spectroscopy.Additionally,the editorial underscores that such lifestyle changes are instrumental not only in resolving NAFLD but also in reversing hepatic steatosis and inflammation.These insights,derived from the research,emphasize the critical role of personalized lifestyle modifications in halting the progression of NAFLD to NASH and even reversing fibrosis,thus offering a template for effective patient management. 展开更多

This editorial delves into the research article by Zeng et al published in the latest issue of World Journal of Gastroenterology.The manuscript contributes significantly to addressing the global health issue of nonalcoholic fatty liver disease(NAFLD)by introducing and validating the Exercise and Diet Adherence Scale(EDAS).The article effectively conveys the importance of the study,highlighting the prevalence of NAFLD,the lack of approved drugs for its treatment,and the crucial role of lifestyle correction.The use of the Delphi method for scale development and the subsequent evaluation of its reliability add scientific rigor to the methodology.The results demonstrate that the scale is correlated with key lifestyle indicators,which makes it a promising tool for assessing patient adherence to interventions.The identification of specific score thresholds for predicting adherence to daily calorie intake and exercise adds practical value to the scale.The differentiation among scores indicative of good,average,and poor adherence enhances its clinical applicability.In conclusion,the manuscript introduces EDAS,a valuable instrument that can contribute substantially to the field of NAFLD research and clinical practice. 展开更多

BACKGROUND The prevalence of nonalcoholic fatty liver disease(NAFLD)in patients with chronic hepatitis B(CHB)has increased in recent clinical practice;however,the relationship between CHB and hepatic steatosis(HS)remains controversial.AIM To shed light on the potential association between NAFLD and hepatitis B virus(HBV)infection.METHODS We conducted a systematic literature search using multiple databases,including PubMed,the Cochrane Library,Web of Science,and EMBASE,to identify relevant studies.Predefined inclusion criteria were used to determine the eligibility of the studies for further analysis.RESULTS Comprehensive meta-analysis software was used for statistical analysis,which covered 20 studies.The results indicated a lower NAFLD susceptibility in HBVinfected individuals(pooled OR=0.87;95%CI=0.69-1.08;I2=91.1%),with diabetes(P=0.015),body mass index(BMI;P=0.010),and possibly age(P=0.061)as heterogeneity sources.Of note,in four studies(6197 HBV patients),HBV-infected individuals had a reduced NAFLD risk(OR=0.68,95%CI=0.51-0.89,P=0.006).A positive link between hyperlipidemia and metabolic syndrome emerged in hepatitis B patients,along with specific biochemical indicators,including BMI,creatinine,uric acid,fasting blood glucose,and homeostasis model assessment of insulin resistance.CONCLUSION HBV infection may provide protection against HS;however,the occurrence of HS in patients with HBV infection is associated with metabolic syndrome and specific biochemical parameters. 展开更多

BACKGROUND Although the etiology of nonalcoholic fatty liver disease(NAFLD)has not been thoroughly understood,the emerging roles of anthropometric indicators in assessing and predicting the risk of NAFLD have been highlighted by accumulating evidence.AIM To evaluate the causal relationships between five anthropometric indicators and NAFLD employing Mendelian randomization(MR)design.METHODS The Anthropometric Consortium provided genetic exposure data for five anthropometric indicators,including hip circumference(HC),waist circumference(WC),waist-to-hip ratio(WHR),body mass index(BMI),and body fat percentage(BF).Genetic outcome data for NAFLD were obtained from the United Kingdom Biobank and FinnGen Consortium.Genome-wide significant single nucleotide polymorphisms were chosen as instrumental variables.Univariable MR(UVMR)and multivariable MR(MVMR)designs with analytical approaches,including inverse variance weighted(IVW),MR-Egger,weighted median(WM),and weighted mode methods,were used to assess the causal relationships between anthropometric indicators and NAFLD.RESULTS Causal relationships were revealed by UVMR,indicating that a higher risk of NAFLD was associated with a perunit increase in WC[IVW:odds ratio(OR)=2.67,95%CI:1.42-5.02,P=2.25×10^(−3)],and BF was causally associated with an increased risk of NAFLD(WM:OR=2.23,95%CI:1.07-4.66,P=0.033).The presence of causal effects of WC on the decreased risk of NAFLD was supported by MVMR after adjusting for BMI and smoking.However,no causal association between BF and NAFLD was observed.In addition,other causal relationships of HC,WHR(BMI adjusted),and BMI with the risk of NAFLD were not retained after FDR correction.CONCLUSION This study establishes a causal relationship,indicating that an increase in WC is associated with a higher risk of NAFLD.This demonstrates that a suitable decrease in WC is advantageous for preventing NAFLD. 展开更多

BACKGROUND Previous research has highlighted correlations between blood cell counts and chronic liver disease.Nonetheless,the causal relationships remain unknown.AIM To evaluate the causal effect of blood cell traits on liver enzymes and nonalcoholic fatty liver disease(NAFLD)risk.METHODS Independent genetic variants strongly associated with blood cell traits were extracted from a genome-wide association study(GWAS)conducted by the Blood Cell Consortium.Summary-level data for liver enzymes were obtained from the United Kingdom Biobank.NAFLD data were obtained from a GWAS meta-analysis(8434 cases and 770180 controls,discovery dataset)and the Fingen GWAS(2275 cases and 372727 controls,replication dataset).This analysis was conducted using the inverse-variance weighted method,followed by various sensitivity analyses.RESULTS One SD increase in the genetically predicted haemoglobin concentration(HGB)was associated with aβof 0.0078(95%CI:0.0059-0.0096),0.0108(95%CI:0.0080-0.0136),0.0361(95%CI:0.0156-0.0567),and 0.0083(95%CI:00046-0.0121)for alkaline phosphatase(ALP),alanine aminotransferase(ALT),aspartate aminotransferase,and gammaglutamyl transferase,respectively.Genetically predicted haematocrit was associated with ALP(β=0.0078,95%CI:0.0052-0.0104)and ALT(β=0.0057,95%CI:0.0039-0.0075).Genetically determined HGB and the reticulocyte fraction of red blood cells increased the risk of NAFLD[odds ratio(OR)=1.199,95%CI:1.087-1.322]and(OR=1.157,95%CI:1.071-1.250).The results of the sensitivity analyses remained significant.CONCLUSION Novel causal blood cell traits related to liver enzymes and NAFLD development were revealed through Mendelian randomization analysis,which may facilitate the diagnosis and prevention of NAFLD. 展开更多

Methods: A rat model of non- alcoholic fatty liver disease was established after 20 weeks of high-fat feeding, and the rats were divided into six groups, normal group, model group, simvastatin group (4 mg/kg), low- dose group of Linggui Zhugan Decoction (2.1 g/kg), medium-dose group of Linggui Zhugan Decoction (4.2 g/kg), and high-dose group of Linggui Zhugan Decoction (8.4 g/kg), and the liver morphological changes of HE staining and oil red O staining after the intervention of Linggui Zhugan Decoction were observed, and the microplate reader detected aspartate aminotransferase, alanine aminotransferase, Four levels of blood lipids. Network pharmacology combined with molecular docking was used to screen the potential mechanism and target of Linggui Zhugan Decoction for the intervention of non-alcoholic fatty liver disease. Results: Linggui Zhugan Decoction significantly improved the levels of alanine aminotransferase and alanine aminotransferase in model rats (P<0.05). HE staining and oil red O staining showed that Linggui Zhugan Decoction significantly reduced liver lipid deposition in rats in the model group. Linggui Zhugan Decoction could significantly reduce the quadruplical levels of blood lipids in model rats (P<0.05). Network pharmacology screened out 10 key targets and 5 key signaling pathways;The molecular docking results showed that the first 20 active ingredients all had good binding ability to the top 10 targets. Conclusion: The results show that Linggui Zhugan Decoction has the effect of regulating blood lipids and improving liver tissue lesions in non-alcoholic fatty liver disease, and preliminarily verifies the regulatory effect of Linggui Zhugan Decoction on lipid metabolism-related genes. 展开更多

Background: The objective of this study was to compare and analyze the variations in clinical indices before and after treatment of type 2 mellitus (T2DM) combined with nonalcoholic fatty liver disease (NAFLD) that were treated with glucagon-like peptide 1 receptor agonists (GLP-1RAs). Methods: The electronic medical record system was utilized to search for a total of 16 patients with type 2 diabetes complicated by NAFLD who were hospitalized at the First Affiliated Hospital of Yangtze University from October 2022 to April 2023 and treated with GLP-1RA for the first time. The clinical indices were compared before and after 12 weeks of treatment with GLP-1RA. Results: The liver-spleen CT ratio (L/S), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) in all patients treated with GLP-1RA after 12 weeks were significantly different (P 0.05). The patients were categorized into two groups based on the types of GLP-1RAs. The changes in L/S, TC, TG, and LDL-C in the long-acting group after treatment were statistically significant (P Conclusions: GLP-1RAs can improve liver function, regulate lipid metabolism, and reduce the severity of fatty liver in patients with T2DM complicated by NAFLD, which demonstrates the importance of clinical applications. 展开更多

Liver cancer is the sixth most commonly diagnosed cancer worldwide,with hepatocellular carcinoma(HCC)comprising most cases.Besides hepatitis B and C viral infections,heavy alcohol use,and nonalcoholic steatohepatitis(NASH)-associated advanced fibrosis/cirrhosis,several other risk factors for HCC have been identified(i.e.old age,obesity,insulin resistance,type 2 diabetes).These might in fact partially explain the occurrence of HCC in non-cirrhotic patients without viral infection.HCC surveillance through effective screening programs is still an unmet need for many nonalcoholic fatty liver disease(NAFLD)patients,and identification of pre-cirrhotic individuals who progress to HCC represents a substantial challenge in clinical practice at the moment.Patients with NASHcirrhosis should undergo systematic HCC surveillance,while this might be considered in patients with advanced fibrosis based on individual risk assessment.In this context,interventions that potentially prevent NAFLD/NASH-associated HCC are needed.This paper provided an overview of evidence related to lifestyle changes(i.e.weight loss,physical exercise,adherence to healthy dietary patterns,intake of certain dietary components,etc.)and pharmacological interventions that might play a protective role by targeting the underlying causative factors and pathogenetic mechanisms.However,well-designed prospective studies specifically dedicated to NAFLD/NASH patients are still needed to clarify the relationship with HCC risk. 展开更多

Nonalcoholic fatty liver disease(NAFLD)is the most common chronic liver dis-ease worldwide.NAFLD comprises a continuum of liver abnormalities from non-alcoholic fatty liver to nonalcoholic steatohepatitis,and can even lead to cirrhosis and liver cancer.However,a well-established treatment for NAFLD has yet to be identified.Exosomes have become an ideal drug delivery tool because of their high transmissibility,low immunogenicity,easy accessibility and targeting.Exosomes with specific modifications,known as engineered exosomes,have the potential to treat a variety of diseases.Here,we review the treatment of NAFLD with engineered exosomes and the potential use of exosomes as biomarkers and therapeutic targets for NAFLD. 展开更多

Nonalcoholic fatty liver disease(NAFLD)is the most rapidly growing contributor to liver mortality and morbidity.Hepatocellular injury in nonalcoholic steatohepatitis(NASH)is caused by an increase in metabolic substrates(glucose,fructose,and fatty acids),leading fatty acids to participate in pathways that cause cellular injury and a poor response to injury.The pathogenesis of this disease is largely associated with obesity,type 2 diabetes,and increasing age.To date,there are no Food and Drug Administration-approved treatments for NAFLD/NASH or its associated fibrosis.Since one of the pathogenic drivers of NASH is insulin resistance,therapies approved for the treatment of type 2 diabetes are being evaluated in patients with NASH.Currently,the glucagon-like peptide-1 receptor agonist(GLP-1RA)semaglutide is a safe,well-studied therapeutic for NAFLD/NASH patients.Existing research demonstrates that semaglutide can increase the resolution of NASH but not improve fibrosis.However,improving the fibrosis of NAFLD is the only way to improve the long-term prognosis of NAFLD.Given the complex pathophysiology of NASH,combining therapies with complementary mechanisms may be beneficial.Researchers have conducted trials of semaglutide in combination with antifibrotic drugs.However,the results have not fully met expectations,and it cannot be ruled out that the reason is the short trial time.We should continue to pay increasing attention to GLP-1RAs. 展开更多

Nonalcoholic fatty liver disease(NAFLD),a leading chronic disease worldwide,affects approximately a quarter of the global population.Nonalcoholic steatohepatitis(NASH)is an advanced form of NAFLD and is more likely to progress to liver fibrosis than simple steatosis.NASH is also identified as the most rapidly growing cause of hepatocellular carcinoma.Although in the past decade,several phase II/III clinical trials have shown promising results in the use of novel drugs targeting lipid synthase,farnesoid X receptor signaling,peroxisome proliferatoractivated receptor signaling,hepatocellular injury,and inflammatory signaling,proven pharmaceutical agents to treat NASH are still lacking.Thus,continuous exploration of the mechanism underlying the pathogenesis of NAFLD and the identification of novel therapeutic targets remain urgent tasks in the field.In the current review,we summarize studies reported in recent years that not only provide new insights into the mechanisms of NAFLD development but also explore the possibility of treating NAFLD by targeting newly identified signaling pathways.We also discuss evidence focusing on the intrahepatic targets involved in the pathogenesis of NAFLD as well as extrahepatic targets affecting liver metabolism and function. 展开更多
