Abstract
BACKGROUND The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing in parallel with obesity and type 2 diabetes. AIM To review the global epidemiology of NAFLD METHODS: We retrieved articles from PubMed using search terms of NAFLD, epidemiology, prevalence, incidence, and comorbidities. RESULTS Over 250 articles were reviewed. In 2016, the global NAFLD prevalence was 25%; this increased to >30% in 2019. Prevalence in Asia, Latin America and Middle East-North Africa (MENA) was 30.8%, 34.5% and 42.6%, respectively. Prevalence increased with age. Although prevalence was higher in men, prevalence in post-menopausal women was similar. NAFLD prevalence was higher in certain subpopulations, especially among the obese and those with metabolic syndrome (MS). However, the prevalence of lean NAFLD was 11.2%. The global prevalence of non-alcoholic steatohepatitis (NASH) is estimated between 2% and 6% in the general population. Approximately 7% of patients with NAFLD have advanced fibrosis; rates were between 21% and 50% among patients with NASH. Overall mortality related to NAFLD was 15-20 per 1000 person-years, and increased substantially in patients with NASH, especially in those with components of MS. Recent data suggest mortality/morbidity from NAFLD is increasing globally but NAFLD awareness remains low among patients and healthcare providers. CONCLUSIONS NAFLD poses a global public health problem with a very high disease burden in Asia, MENA and Latin America. Research is needed to better quantify the full impact of NAFLD and to develop strategies to improve awareness and risk stratification.

Abstract
INTRODUCTION Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide and closely interconnected to the metabolic syndrome. Liver-specific and systemic signaling pathways orchestrating glucose and fatty acid metabolism contribute to intrahepatic accumulation of lipids and inflammatory processes eventually causing disease progression to nonalcoholic steatohepatitis (NASH), liver fibrosis, and cirrhosis. Since a high number of key regulatory genes regarding liver homeostasis are directly mediated via thyroid hormone (TH) signaling, targeting TH receptors (TRs) represent a promising therapeutic potential for the treatment of NAFLD. AREAS COVERED In this review, we elucidate the effects of TH on metabolic regulations in the liver via local availability and actions. We discuss recent advances and the potential impact of thyromimetics in basic research and clinical trials including liver-targeted and TRβ-specific agents for the treatment of NAFLD. EXPERT OPINION Unselective TR targeting can be accompanied by negative side effects due to high TRβ expression in other organs and TRα-mediated effects. Recent advances in drug development and the introduction of liver-targeted thyromimetics selectively activating TRβ such as Resmetirom (MGL-3196) and VK2809 bring new hope of translating the knowledge on local TH effects into effective hepatic lipid-clearing therapies against NASH.

Abstract
BACKGROUND Sialic acid is often the distal sugar on glycoconjugates, and sialidases are enzymes that remove this sugar. In fibrotic lesions in human and mouse lungs, there is extensive desialylation of glycoconjugates, and upregulation of sialidases including the extracellular sialidase NEU3. In the bleomycin model of pulmonary fibrosis, mice lacking NEU3 (Neu3-/-) showed strongly attenuated bleomycin-induced weight loss, lung damage, inflammation, and fibrosis. This indicates that NEU3 is necessary for the full spectrum of bleomycin-induced pulmonary fibrosis. METHODS To determine if NEU3 is sufficient to induce pulmonary fibrosis, recombinant murine NEU3 and a mutated inactive recombinant murine NEU3 protein were produced. Mice were given recombinant NEU3 proteins by oropharyngeal aspiration, either alone or 10 days after bleomycin challenge. Over the course of 21 days, mice were assessed for weight change, and after euthanasia, bronchoalveolar lavage fluid cells and lung tissue were assessed for inflammation and fibrosis. RESULTS Aspiration of recombinant murine NEU3 caused inflammation and fibrosis in the lungs, while inactive NEU3 caused inflammation but not fibrosis. Mice were also treated with recombinant murine NEU3 starting 10 days after bleomycin. In male but not female mice, recombinant murine NEU3 increased inflammation and fibrosis. Inactive NEU3 did not enhance bleomycin-induced lung fibrosis. CONCLUSION These results suggest that NEU3 is sufficient to induce fibrosis in the lungs, that aspiration of NEU3 has a greater effect on male mice, and that this effect is mediated by NEU3's enzymic activity.

Effect of hepatic steatosis and associated metabolic comorbidities on health-related quality of life in people living with HIV. Hepatol Commun 2022; 6:2011-2021. [PMID: 35411570 PMCID: PMC9315116 DOI: 10.1002/hep4.1958] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 02/17/2022] [Accepted: 03/11/2022] [Indexed: 12/31/2022] Open
Abstract
Hepatic steatosis (HS) related to nonalcoholic fatty liver disease (NAFLD) is increasing globally. In people living with human immunodeficiency virus (PLWH) risk factors of HS are increased. The impact of HS on outcomes and in particular health-related quality of life (HRQL) in PLWH remains unknown. The aim of this cross-sectional cohort study (FLASH, Prevalence of Advanced Fibrosis in Patients Living With HIV) was to determine the contribution of HS on HRQL in PLWH and to identify confounders on HRQL. A total of 245 PLWH were prospectively enrolled. HS was assessed using vibration-controlled transient elastography and defined as a controlled attenuation parameter (CAP) of ≥ 275 dB/m. The analysis was performed between CAP < 275 and ≥ 275 dB/m. The generic European Quality-of-Life 5-Dimension 5-Level questionnaire was used to determine differences in the HRQL. Univariable and multivariable linear regression models were applied to identify predictors with impaired HRQL in both groups. In this cohort, 65% (n = 160) presented without and 35% (n = 85) with HS, of whom most had NAFLD (n = 65, 76.5%). The HRQL (UI-value) was significantly lower in PLWH and steatosis (0.86 ± 0.18) in comparison with no steatosis (0.92 ± 0.13). Unemployment (p = 0.025) and waist circumference (p = 0.017) remained independent predictors of a poor HRQL in the steatosis subgroup. In turn, age (p = 0.045), female sex (p = 0.030), body mass index (p = 0.010), and arterial hypertension (p = 0.025) were independent predictors of a low HRQL in the subgroup without steatosis. Conclusion: HS and metabolic comorbidities negatively affect the HRQL. Addressing these factors may improve patient-reported and liver-related outcomes in PLWH.

Abstract
BACKGROUND The global prevalence of non-alcoholic steatohepatitis (NASH) is increasing, such that NASH is predicted to become the leading cause of liver transplantation (LT) in the US by 2025. Despite this, data on the economic burden of NASH are limited. OBJECTIVES This systematic literature review aimed to summarise and critically evaluate studies reporting on the economic burden of NASH and identify evidence gaps for subsequent research. METHODS Medline, EMBASE, the Cochrane Library and EconLit were searched up to 6 January 2021 for English language articles published from January 2010 to January 2021 inclusive that reported economic outcomes of a NASH population or subpopulation. Evidence was presented and synthesised using narrative data analysis, and quality was assessed by two reviewers using an 11-item checklist developed for economic evaluations and adapted to cost of illness. RESULTS Fourteen studies were included, of which five presented data on costs and resource use, four on costs only and five on resource use only. Overall, NASH is associated with a significant and increasing economic burden in terms of healthcare resource utilisation (HCRU) and direct and indirect costs. This burden was higher among NASH patients with advanced (fibrosis stage 3-4) versus early (fibrosis stage 0-2) disease, symptomatic versus asymptomatic disease and for patients with complications or comorbidities versus those without. In LT patients, those with NASH as the primary indication had greater HCRU and higher costs compared with non-NASH indications such as hepatitis B and C viruses. Considerable variability in HCRU and costs was seen across the US and Europe, with the highest costs seen in the US. The quality of the included studies was variable, and the studies themselves were heterogeneous in terms of study methodology, patient populations, comorbidities, follow-up time and outcomes measured. CONCLUSIONS This review highlights a general scarcity of NASH-specific economic outcomes data. Despite this, the identified studies show that NASH is associated with a significant economic burden in terms of increased HCRU, and high direct medical and non-medical costs and societal burden that increases with disease severity or when patients have complications or comorbidity. More national-level NASH prevalence data are needed to generate accurate forecasts of HCRU and costs in the coming decades. FUNDING Novo Nordisk A/S, Søborg, Denmark.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is considered a highly prevalent disease associated with various co-morbidities that lead to socioeconomic burden. Despite large-scale investigation, no pharmacological treatment has been approved specifically for NAFLD to date. Lifestyle modifications and diet are regarded as highly beneficial for the management of NAFLD, albeit with poor compliance, thus rendering pharmacological treatment highly important. Based on the current failure to discover a “magic bullet” to treat all patients with NAFLD and considering the multifaceted pathophysiology of the disease, combination therapies may be considered to be a rational alternative approach. In this regard, several drug categories have been considered, including, but not limited to, lipid-lowering, anti-hypertensive, glucose-lowering, anti-obesity, anti-oxidant, anti-inflammatory and anti-fibrotic medications. The aim of this review is, in addition to summarizing some of the multiple factors contributing to the pathophysiology of NAFLD, to focus on the efficacy of pharmacological combinations on the management of NAFLD. This may provide evidence for a more personalized treatment of patients with NAFLD in the future.

Abstract
Non-alcoholic fatty liver disease (NAFLD) includes a range of hepatic manifestations, starting with liver steatosis and potentially evolving towards non-alcoholic steatohepatitis (NASH), cirrhosis or even hepatocellular carcinoma. NAFLD is a major health burden, and its incidence is increasing worldwide. Although it is primarily a disease of disturbed metabolism, NAFLD involves several immune cell-mediated inflammatory processes, particularly when reaching the stage of NASH, at which point inflammation becomes integral to the progression of the disease. The hepatic immune cell landscape is diverse at steady state and it further evolves during NASH with direct consequences for disease severity. In this Review, we discuss current concepts related to the role of immune cells in the onset and progression of NASH. A better understanding of the mechanisms by which immune cells contribute to NASH pathogenesis should aid the design of innovative drugs to target NASH, for which current therapeutic options are limited.

Abstract
A growing body of evidence suggests interplay between the gut microbiota and the pathogenesis of nonalcoholic fatty liver disease (NAFLD). However, the role of the gut microbiome in early detection of NAFLD is unclear. Prospective studies are necessary for identifying reliable, microbiome markers for early NAFLD. We evaluated 2487 individuals in a community-based cohort who were followed up 4.6 years after initial clinical examination and biospecimen sampling. Metagenomic and metabolomic characterizations using stool and serum samples taken at baseline were performed for 90 participants who progressed to NAFLD and 90 controls who remained NAFLD free at the follow-up visit. Cases and controls were matched for gender, age, body mass index (BMI) at baseline and follow-up, and 4-year BMI change. Machine learning models integrating baseline microbial signatures (14 features) correctly classified participants (auROCs of 0.72 to 0.80) based on their NAFLD status and liver fat accumulation at the 4-year follow up, outperforming other prognostic clinical models (auROCs of 0.58 to 0.60). We confirmed the biological relevance of the microbiome features by testing their diagnostic ability in four external NAFLD case-control cohorts examined by biopsy or magnetic resonance spectroscopy, from Asia, Europe, and the United States. Our findings raise the possibility of using gut microbiota for early clinical warning of NAFLD development.

Prevalence and Risk Factors of Advanced Liver Fibrosis in a Population-Based Study in Germany. Hepatol Commun 2022; 6:1457-1466.

Abstract
The prevalence of liver disease, and especially of advanced liver fibrosis, in the German population is poorly defined. The aim of the study was to explore liver enzymes and surrogate scores of hepatic steatosis and advanced hepatic fibrosis in a population-based cohort study in Germany. In the cross-sectional population-based Gutenberg Health study, data of 14,950 participants enrolled between 2007 and 2012 were captured and analyzed. The distribution of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), fatty liver index (FLI), and Fibrosis-4 (FIB-4) score, as well as the underlying risk factors, were assessed by regression models. Elevated liver enzymes in this population-based sample were seen in 19.9% for ALT, 12.8% for AST, and 14% for GGT. Risk factors for liver disease included alcohol use and the presence of the metabolic syndrome, which were both risk factors associated with increased liver enzymes. The FLI suggested that 37.5% of the population exhibited hepatic steatosis and 1.1% of patients exhibited a FIB-4 above the upper cutoff, while 19.2% were in the intermediate range. Interestingly, advanced fibrosis was significantly more frequent in men compared with women (FIB-4: 1.5% vs. 0.6% [P < 0.0001]; NFS: 3.6% vs. 1.9% [P < 0.0001]). In addition, age was a relevant risk factor for exhibiting a noninvasive surrogate score suggestive of advanced fibrosis in the current study population. Conclusion: Elevated liver enzymes were seen in almost a fifth of the German population. At the population-based level, the prevalence of advanced fibrosis was estimated at 1% in Germany.

Derivation and validation of the nonalcoholic fatty liver disease cirrhosis score (NCS) to distinguish bridging fibrosis from cirrhosis. Eur J Intern Med 2022; 98:53-60. [PMID: 35058147 DOI: 10.1016/j.ejim.2021.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 12/04/2021] [Accepted: 12/08/2021] [Indexed: 12/20/2022]
Abstract
Separation of bridging fibrosis from cirrhosis in non-alcoholic fatty liver disease (NAFLD) is critical to guide management. Therefore, it was the aim of this study to develop an easy-to-perform score distinguishing F3 and F4 fibrosis in NAFLD. A derivation cohort comprising 251 NAFLD patients with F3 or F4 was used to develop the NAFLD Cirrhosis Score (NCS). The NCS was validated in three independent cohorts with liver histology comprising 1666 participants from the STELLAR trials, 47 patients from China and 2058 patients from the European NAFLD Registry. A model including INR, gGT, ALT, platelets and age discriminated best between patients with bridging fibrosis and cirrhosis with an area under the curve (AUC) of 0.733 (95%CI 0.671-0.795). The diagnostic performance of the NCS was similar in the STELLAR studies (AUC 0.700; 95%CI 0.680-0.730) and a smaller cohort from China (AUC 0.727; 95%CI 0.533-0.921). In the European NAFLD Registry, spanning all histological fibrosis stages, the NCS exhibited an AUC of 0.798 (95%CI 0.766-0.830) to detect cirrhosis. We derived two NCS cut-off values (<64.5 and >79.17) to classify patients at low, intermediate, or high risk for the presence of cirrhosis. Using these cut-offs, further diagnostic workup could be avoided by ruling in or ruling out cirrhosis in approximately half of the patients. Furthermore, NCS identified patients at risk for progression to cirrhosis in the F3 cohort and liver-related outcomes in the F4 cohort. CONCLUSION: The NCS is a simple tool to improve the identification of compensated cirrhosis within the large group of advanced disease stage and provides prognostic information. Overall, the differentiation of F3 from F4 disease using standard laboratory remains difficult and does not exceed moderate accuracy.

Abstract
PURPOSE The aim of this study was to assess the ability of ultrasound biomicroscopy (UBM) to diagnose the initial stages of nonalcoholic fatty liver disease (NAFLD) in a rat model. METHODS Eighteen male Wistar rats were allocated to control or experimental groups. A high-fat diet (HFD) with 20% fructose and 2% cholesterol, resembling a common Western diet, was fed to animals in the experimental groups for up to 16 weeks; those in the control group received a regular diet. A 21 MHz UBM system was used to acquire B-mode images at specific times: baseline (T0), 10 weeks (T10), and 16 weeks (T16). The sonographic hepatorenal index (SHRI), based on the average ultrasound image gray-level intensities from the liver parenchyma and right renal cortex, was determined at T0, T10, and T16. The liver specimen histology was classified using the modified Nonalcoholic Steatohepatitis Clinical Research Network NAFLD activity scoring system. RESULTS The livers in the animals in the experimental groups progressed from sinusoidal congestion and moderate macro- and micro-vesicular steatosis to moderate steatosis and frequent hepatocyte ballooning. The SHRI obtained in the experimental group animals at T10 and T16 was significantly different from the SHRI of pooled control group. No significant difference existed between the SHRI in animals receiving HFD between T10 and T16. CONCLUSION SHRI measurement using UBM may be a promising noninvasive tool to characterize early-stage NAFLD in rat models.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a growing epidemic that encompasses three distinct clinical phenotypes: uncomplicated fatty liver, nonalcoholic steatohepatitis (NASH) and NASH-related cirrhosis with its complications, including hepatocellular carcinoma. To date, no pharmacological treatments have been approved and lifestyle modifications including reduced caloric intake targeting a 7%-10% weight loss from baseline assessment represent the standard approach. Mediterranean diet has been recommended as the best dietary pattern since it is easy to follow and, independently of caloric intake its nutritional components have beneficial metabolic effects that not only improve steatosis but also risk factors for cardiovascular events, the leading cause of morbidity/mortality in individuals with NAFLD. Other dietary patterns such as ketogenic diet and Dietary Approach to Stop Hypertension (DASH) diet can be used in patients with NAFLD. Recently, intermittent fasting diets have gained popularity among healthy individuals and have been proposed as a safe and effective treatment for the metabolic syndrome in experimental and in a few human studies. In this narrative review, we aim to summarize the evidence for the available dietary approaches for patients with NAFLD.

Abstract
Non-Alcoholic Fatty Liver Disease (NAFLD) is a progressive liver disease that affects up to 30% of worldwide population, of which up to 25% progress to Non-Alcoholic SteatoHepatitis (NASH), a severe form of the disease that involves inflammation and predisposes the patient to liver cirrhosis. Despite its epidemic proportions, there is no reliable diagnostics that generalizes to global patient population for distinguishing NASH from NAFLD. We performed a comprehensive multicohort analysis of publicly available transcriptome data of liver biopsies from Healthy Controls (HC), NAFLD and NASH patients. Altogether we analyzed 812 samples from 12 different datasets across 7 countries, encompassing real world patient heterogeneity. We used 7 datasets for discovery and 5 datasets were held-out for independent validation. Altogether we identified 130 genes significantly differentially expressed in NASH versus a mixed group of NAFLD and HC. We show that our signature is not driven by one particular group (NAFLD or HC) and reflects true biological signal. Using a forward search we were able to downselect to a parsimonious set of 19 mRNA signature with mean AUROC of 0.98 in discovery and 0.79 in independent validation. Methods for consistent diagnosis of NASH relative to NAFLD are urgently needed. We showed that gene expression data combined with advanced statistical methodology holds the potential to serve basis for development of such diagnostic tests for the unmet clinical need.

Abstract
The scavenger receptor superfamily represents a highly diverse collection of evolutionarily-conserved receptors which are known to play key roles in host homeostasis, the most prominent of which is the clearance of unwanted endogenous macromolecules, such as oxidized low-density lipoproteins, from the systemic circulation. Members of this family have also been well characterized in their binding and internalization of a vast range of exogenous antigens and, consequently, are generally considered to be pattern recognition receptors, thus contributing to innate immunity. Several studies have implicated scavenger receptors in the pathophysiology of several inflammatory diseases, such as Alzheimer's and atherosclerosis. Hepatic resident cellular populations express a diverse complement of scavenger receptors in keeping with the liver's homeostatic functions, but there is gathering interest in the contribution of these receptors to hepatic inflammation and its complications. Here, we review the expression of scavenger receptors in the liver, their functionality in liver homeostasis, and their role in inflammatory liver disease and cancer.

Abstract
Nonalcoholic fatty liver disease [NAFLD] is a condition affecting a vast portion of the worldwide population. The presence of underlying fibrosis is the strongest predictor of long-term outcomes and mortality, with a graduated increase in liver-related morbidity and mortality with progression from moderate fibrosis tobiomarkers targeting collagen turnover and extracellular matrix remodeling FibroTest FAST™, Velacur™, MRE]. While many of these provide a robust, stand alone value, the accuracy of these noninvasive tests markedly increase when used in combination or in sequential order with one another. There is not a uniform consensus demonstrating superiority of any specific test. Given the growing role and accuracy of these tests, they should have an expanding role in the assessment of fibrosis across this patient population and obviate the need for liver biopsy in a large portion of patients. Future clinical studies should focus on validating these novel biomarkers, as well as optimizing the sequential or algorithmic testing when combining these noninvasive tests.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent condition that requires a comprehensive and coordinated response across sectors and disciplines. AIMS In the absence of a multisectoral framework to tackle this condition, we developed one using the sustainable development goals (SDGs) as the basis for converging thinking about the design and delivery of public health responses. METHODS A multidisciplinary group identified the SDG targets and indicators for inclusion in the new framework through a two-stage process. Firstly, a core team of three researchers independently reviewed the 169 targets and 231 indicators of the SDGs to select a shortlist. Over two Delphi rounds, a multidisciplinary group of 12 experts selected which of the shortlisted targets and indicators to include. Respondents also provided written feedback on their selection. Targets and indicators with 75% or greater agreement were included in the final framework. RESULTS The final framework comprises 16 targets-representing 9% of all targets and 62% (16/26) of the shortlisted targets-and seven indicators, accounting for 50% (7/14) of the shortlisted indicators and 3% of all indicators. The selected targets and indicators cover a broad range of factors, from health, food and nutrition to education, the economy, and the built environment. CONCLUSIONS Addressing the challenge of NAFLD will require a re-envisioning of the liver health landscape, with greater focus on joined-up systems thinking and action. This new framework can help guide this process, including by outlining the stakeholders with whom the liver health community needs to engage.

Abstract
Non-Alcoholic Fatty Liver Disease (NAFLD) is the most common chronic liver disease, with a global prevalence of approximately 24% in the general population. It is caused by fat accumulation in the liver secondary to insulin resistance, visceral obesity, and/or features of metabolic syndrome. A genetic susceptibility contributes to the phenotype, accounting for a more severe course of liver disease and the observed clinical variability. In fact, despite liver steatosis being considered a relatively benign entity, inflammation related to oxidative stress and lipid-derived damage may lead to non-alcoholic steatohepatitis (NASH), which constitutes the progressive disease. Accumulation of hepatic fibrosis can lead to cirrhosis and provide the environment for hepatocellular carcinoma. Obese and diabetic individuals represent a well-acknowledged high risk population. The assessment of liver fibrosis plays a crucial role in clinical setting, as liver-related mortality increases parallel to fibrosis stage. A liver biopsy is currently considered the reference standard for the diagnosis of NASH and the fibrosis stage, but many non-invasive tools are used with the aim of replacing histology for diagnosis and prognosis purposes. Blood based scores and liver stiffness are the most widely used and validated tools to assess liver fibrosis. Management of NAFLD resides on environmental interventions, including diet and physical activity to induce weight loss, and avoiding harmful nutrients, including fructose-sweetened beverages and high glycemic index foods, that are directly implied in liver injury. Multiple trials with investigational drugs are currently explored to treat fibrosing NASH, with promising results and it can be expected that a liver direct therapy aiming at steatohepatitis and fibrosis will become available soon.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a potentially serious liver disease that affects approximately one-quarter of the global adult population, causing a substantial burden of ill health with wide-ranging social and economic implications. It is a multisystem disease and is considered the hepatic component of metabolic syndrome. Unlike other highly prevalent conditions, NAFLD has received little attention from the global public health community. Health system and public health responses to NAFLD have been weak and fragmented, and, despite its pervasiveness, NAFLD is largely unknown outside hepatology and gastroenterology. There is only a nascent global public health movement addressing NAFLD, and the disease is absent from nearly all national and international strategies and policies for non-communicable diseases, including obesity. In this global Delphi study, a multidisciplinary group of experts developed consensus statements and recommendations, which a larger group of collaborators reviewed over three rounds until consensus was achieved. The resulting consensus statements and recommendations address a broad range of topics - from epidemiology, awareness, care and treatment to public health policies and leadership - that have general relevance for policy-makers, health-care practitioners, civil society groups, research institutions and affected populations. These recommendations should provide a strong foundation for a comprehensive public health response to NAFLD.

Abstract
OBJECTIVES To evaluate the diagnostic performance of liver surface nodularity (LSN) for the assessment of advanced fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). METHODS We retrospectively analysed patients with pathologically proven NAFLD who underwent liver MRI. Demographic, clinical, and laboratory data (including FIB-4 scores) were gathered. The SAF score was used to assess NAFLD. MRI-proton density fat fraction (PDFF) and LSN were determined on pre-contrast MR sequences. ROC curve analysis was performed to evaluate the diagnostic performance of MRI-LSN for the diagnosis of advanced (F3-F4) liver fibrosis. RESULTS The final population included 142 patients. Sixty-seven (47%) patients had non-alcoholic steatohepatitis (NASH), and 52 (37%) had advanced fibrosis. The median MRI-PDFF increased with the grades of steatosis: 8.1%, 18.1%, and 31% in S1, S2, and S3 patients, respectively (p < 0.001). The area under the ROC curve (AUC) of MRI-LSN ≥ 2.50 was 0.838 (95%CI 0.767-0.894, sensitivity 67.3%, specificity 88.9%, positive and negative predictive values 77.8% and 82.5%, respectively) for the diagnosis of advanced fibrosis. Combining FIB-4 and MRI-LSN correctly classified 103/142 (73%) patients. This was validated in an external cohort of 75 patients. CONCLUSIONS MRI-LSN has good diagnostic performance in diagnosis of advanced fibrosis in NAFLD patients. A combination of FIB-4 and MRI-LSN derived from pre-contrast MRI could be helpful to detect advanced fibrosis. KEY POINTS • MRI-LSN ≥ 2.5 was accurate for the diagnosis of advanced hepatic fibrosis in NAFLD patients. • The combination of FIB-4 and MRI-LSN improved the detection of advanced fibrosis. • MRI-LSN can be easily derived by unenhanced MRI sequences that are routinely acquired.

Abstract
BACKGROUND Studies investigating a potential association between hypothyroidism and non-alcoholic fatty liver disease (NAFLD) showed conflicting results and large-scale population-based data from Germany on this topic are currently missing. OBJECTIVE It was the aim of this analysis to investigate the impact of thyroid gland disorders on the prevalence of NAFLD in Germany. METHODS In this case-control study, using the German disease Analyzer database (IQVIA), NAFLD patients were matched to patients without NAFLD by age, sex, index year, treating physician, diabetes mellitus type II, and obesity. The main outcome of the study was an association between thyroid gland disorders (hypothyroidism, hyperthyroidism and autoimmune thyroiditis) and incident NAFLD and was evaluated using logistic regression analyses. RESULTS 57,483 patients with NAFLD were matched to 57,483 patients without liver disease. Mean age of the cohort was 60.3 years (±14.1) and 52.3% were men. In regression analyses, hypothyroidism (OR 1.17, 95% CI 1.10 - 1.24, p < 0.001) as well as autoimmune thyroiditis (OR 1.53, 95% CI 1.35-1.73, p < 0.001) were associated with a higher risk of NAFLD. In contrast, hyperthyroidism was associated with a lower risk of NAFLD (OR 0.85, 95% CI 0.77-0.94, p < 0.001). The effect of hypothyroidism on the prevalence of NAFLD remained significant across men (OR 1.31, 95% CI 1.15-1.48) as well as women (OR 1.12, 95% CI 1.05-1.21). CONCLUSION Hypothyroidism seems to be a risk factor for incident NAFLD.

Abstract
INTRODUCTION The global burden of liver disease is increasing, and nonalcoholic fatty liver disease (NAFLD) is among the most common chronic liver diseases in Asia, Europe, North and South America. The field of noninvasive diagnostic and their role in staging, but also predicting outcome is evolving rapidly. There is a high-unmet need to stage patients with NAFLD and to identify the subset of patients at risk of progression to end-stage liver disease. AREAS COVERED The review covers all established diagnostic blood-based and imaging biomarkers to stage and grade NAFLD. Noninvasive surrogate scores are put into perspective of the available evidence and recommended use. The outlook includes genetics, combined algorithms, and artificial intelligence that will allow clinicians to guide and support the management in both early and later disease stages. EXPERT OPINION In the future, these diagnostics tests will help clinicians to establish patient care pathways and support the identification of relevant subgroups for monitoring and pharmacotherapy. In addition, researchers will be guided to better understand available scores and support the development of future prediction systems. These will likely include multiparametric aspects of the disease and machine learning algorithms will refine their use and integration with large datasets.

Abstract
Current treatment recommendations for non-alcoholic fatty liver disease (NAFLD) rely heavily on lifestyle interventions. The Mediterranean diet and physical activity, aiming at weight loss, have shown good results in achieving an improvement of this liver disease. However, concerns related to compliance and food accessibility limit the feasibility of this approach, and data on the long-term effects on liver-related outcomes are lacking. Insulin resistance is a central aspect in the pathophysiology of NAFLD; therefore, interventions aiming at the improvement of insulin sensitivity may be preferable. In this literature review, we provide a comprehensive summary of the available evidence on nutritional approaches in the management of NAFLD, involving low-calorie diets, isocaloric diets, and the novel schemes of intermittent fasting. In addition, we explore the harmful role of single nutrients on liver-specific key metabolic pathways, the role of gene susceptibility and microbiota, and behavioral aspects that may impact liver disease and are often underreported in clinical setting. At present, the high variability in terms of study populations and liver-specific outcomes within nutritional studies limits the generalizability of the results and highlights the urgent need of a tailored and standardized approach, as seen in regulatory trials in Non-Alcoholic Steatohepatitis (NASH).
