Abstract
Non-alcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease, affecting approximately 25% of the world's population. Recently, because of the sedentary lifestyle and overnutrition resulting from urbanisation, the burden of NAFLD has rapidly increased in many Asian countries. Currently, the prevalence of NAFLD in Asia is approximately 30%, as is the case in many Western countries. In Asia, the prevalence and presentation of NAFLD vary widely across regions because of the substantial diversity in race, socioeconomic status and living environment. Furthermore, the dual aetiology of fatty liver, particularly with viral hepatitis in Asia, makes it complex and challenging to manage. Because Asians are likely to have central adiposity and insulin resistance, approximately 7%-20% of non-obese Asians with body mass indexes of less than 25 kg/m2 are estimated to have NAFLD. Accumulating evidence indicates that NAFLD is associated with various extrahepatic comorbidities such as cardiovascular disease, chronic kidney disease, malignancy, in addition to liver-specific complications. Therefore, NAFLD should be managed as a multisystem disease in conjunction with metabolic syndrome. Lifestyle modification remains the basis of NAFLD management, but few patients can achieve adequate weight loss and maintain it long term. While various pharmacological agents are in phase 3 trials for steatohepatitis, Asian patients are underrepresented in most trials. This article reviews the epidemiological trends, clinical features, optimal assessment and current management practices for NAFLD in Asia.

Non-Invasive Detection of Fibrotic NASH in NAFLD Patients with Low or Intermediate FIB-4. J Clin Med 2022; 11:jcm11154394. [PMID: 35956017 PMCID: PMC9369177 DOI: 10.3390/jcm11154394] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 07/18/2022] [Accepted: 07/24/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Non-alcoholic steatohepatitis (NASH) and fibrosis are the main prognostic factors in non-alcoholic fatty liver disease (NAFLD). The FIB-4 score has been suggested as an initial test for the exclusion of progressed fibrosis. However, increasing evidence suggests that also NASH patients with earlier fibrosis stages are at risk of disease progression, emphasizing the need for improved non-invasive risk stratification. Methods: We evaluated whether the apoptosis biomarker M30 can identify patients with fibrotic NASH despite low or intermediate FIB-4 values. Serum M30 levels were assessed by ELISA, and FIB-4 was calculated in an exploration (n = 103) and validation (n = 100) cohort of patients with histologically confirmed NAFLD. Results: The majority of patients with low FIB-4 (cut-off value < 1.3) in the exploration cohort revealed increased M30 levels (>200 U/L) and more than 80% of them had NASH, mostly with fibrosis. NASH was also detected in all patients with intermediate FIB-4 (1.3 to 2.67) and elevated M30, from which ~80% showed fibrosis. Importantly, in the absence of elevated M30, most patients with FIB-4 < 1.3 and NASH showed also no fibrosis. Similar results were obtained in the validation cohort. Conclusions: The combination of FIB-4 with M30 enables a more reliable identification of patients at risk for progressed NAFLD and might, therefore, improve patient stratification.

Risk stratification of hepatocellular carcinoma incidence using a fibrosis-4-based prediction model in patients with chronic hepatitis C receiving antiviral therapy: a nationwide real-world Taiwanese cohort study. Am J Cancer Res 2022; 12:3164-3174. [PMID: 35968345 PMCID: PMC9360245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Accepted: 05/23/2022] [Indexed: 06/15/2023] Open
Abstract
A total of 1,589 patients who had received interferon-based treatment were enrolled and analyzed for the risk of hepatocellular carcinoma (HCC) in a real-world nationwide Taiwanese chronic hepatitis C cohort (T-COACH). We aimed to stratify HCC risk by non-invasive fibrosis index-based risk model. Of 1589 patients, 1363 (85.8%) patients achieved sustained virological response (SVR). Patients with SVR had 1, 3, 5 and 10-year cumulative HCC incidence rates of 0.55%, 1.87%, 3.48% and 8.35%, respectively. A Cox proportional hazards model revealed that non-SVR (adjusted hazard ratio [aHR]: 1.92, 95% confidence interval [CI]: 1.19-3.12, p = 0.008), diabetes mellitus (aHR: 2.11, 95% CI: 1.25-3.55, p = 0.005), and fibrosis (FIB)-4 at the end of follow-up (EOF; aHR: 5.60, 95% CI: 2.97-10.57, p < 0.0001) were independent predictors of HCC. Risk score models based on the three predictors were developed to predict HCC according to aHR. In model 1, the 10-year cumulative incidence rates of HCC were 43.35% in patients at high risk (score 9-10), 25.48% in those at intermediate risk (score 6-8), and 4.06% in those at low risk (score 3-5) of HCC. In model 2, the 10-year cumulative incidence rates of HCC were 39.64% in patients at high risk (at least two risk predictors), 19.12% in those at intermediate risk (with one risk predictor), and 2.52% in those at low risk (without any risk predictors) of HCC. The FIB-4-based prediction model at EOF could help stratify the risk of HCC in patients with chronic hepatitis C after antiviral treatment.

Abstract
AIM Individuals with high 1-hour post-load glucose (1-h PG > 155 mg/dl; 8.6 mmol/l) during an oral glucose tolerance test are at increased risk of type 2 diabetes (T2D) and cardiovascular complications, hepatic steatosis, and mortality. However,the clinical relevance of 1-h PG for the severity of hepatic fibrosis risk remains undefined. METHODS Cross-sectional data of the CATAMERI study (n = 2335) were analyzed. Participants underwent anthropometric measurements, liver enzyme determinations, cardiometabolic profiling, and a75-gram oral glucose tolerance test, including fasting, 1-h and 2-h PG determinations and measurement of FIB-4 score to assess degree of hepatic fibrosis. Multivariable logistic regression analysis was performed to evaluate risk of advanced hepatic fibrosis with worsening glycemic status. RESULTS We stratifiedthe study group into 6 categories based on glycemic status: normal glucose tolerance (NGT) 1h-PG Low, NGT 1h-PG High, iIFG 1h-PG Low, iIFG 1h-PG High, IGT, and newly detected T2D. Anthropometric and cardiometabolic profiles worsened gradually with glycemic status. Moreover, compared to NGT-1h-PG Low group, worsening glycemic status was significantly associated with the severity of fibrosis, independent of other significant clinical risk factors. CONCLUSIONS 1-PG is a valuable tool for stratifying subjects with NGT or IFG at heightened risk of hepatic fibrosis requiring further evaluation with elastography.

Abstract
Chronic hepatitis B (CHB) patients with low disease activity are at risk of liver fibrosis. The age-adjusted fibrosis-4 index (FIB4-AA), developed in our previous publication, and was implemented to evaluate the tendency of liver fibrosis in these patients. We aimed to investigate the rate of liver fibrosis in CHB patients with low disease activity. Resuming our previous study, the FIB-4 changes of 244 antiviral treatment-naïve CHB patients, with a total of 1243.48 person-years, were reviewed. Among the cohort, patients were categorized as FIB4-AA positive or negative according to the results of their last FIB4-AA minus their initial FIB-4 during at least 18 months of observation time. The compound annual growth rate (CAGR) of FIB-4 was calculated for the FIB4-AA positive and negative groups. The assumed healthy controls had an FIB-4 CAGR calculated to be 2.34% for both men and women, while the FIB-4 CAGR of the whole study cohort was 2.84% ± 6.01%. FIB4-AA positive effectively identifies CHB patients with higher mean FIB-4 CAGR (7.11% ± 3.88% vs. -2.36% ± 3.52%, p < 0.0001). Overweight CHB patients had 10 times smaller mean FIB-4 CAGR than lean ones (0.38% ± 10.35% vs. 3.83% ± 8.88%, p = 0.009). An increase in FIB4-AA over at least 18 months in CHB patients with relatively low disease activity meant they were at greater risk of liver fibrosis, and these patients had a mean FIB-4 CAGR of 7.11%. The FIB-4 CAGR was compatible with the findings of previous studies on the collagen proportionate area in viral hepatitis patients.

Abstract
BACKGROUND AND AIMS Aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4) are widely used to assess liver fibrosis in chronic hepatitis B virus (HBV) infection. Currently, the definition of normal alanine aminotransferase (ALT) is controversial. We aimed to examine the diagnostic value of APRI and FIB-4 in chronic HBV carriers with different upper limits of normal (ULNs) for ALT. METHODS 581 chronic HBV carriers were divided into the following four groups based on different ULNs for ALT: chronic HBV carriers I, II, III, and IV. Furthermore, 106 chronic HBV carriers formed an external validation group. Predictive values of APRI and FIB-4 were elucidated using the area under the curve (AUC). A liver fibrosis-predictive model-GPSA (named for its measure of gamma glutamyl transpeptidase, platelet count, HBsAg and albumin) was developed using multivariate logistic regression analysis. RESULTS In chronic HBV carriers I, the AUCs of APRI and FIB-4 were 0.680 and 0.609 for significant fibrosis and 0.678 and 0.661 for cirrhosis, respectively. The AUCs of GPSA for significant fibrosis in the training group, internal group, and external validation group were 0.877, 0.837, and 0.871, respectively. The diagnostic value of GPSA differed among chronic HBV carriers I, II, III, and IV, with AUCs for significant fibrosis being 0.857, 0.853, 0.868, and 0.905 and AUCs for cirrhosis being 0.901, 0.905, 0.886, and 0.913, respectively. GPSA showed a higher diagnostic value than APRI and FIB-4 for predicting significant fibrosis in the four groups. CONCLUSIONS The GPSA model allows for accurate diagnosis of liver fibrosis in chronic HBV carriers with different ULN for ALT.

Abstract
Background Aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4) are the two most widely studied noninvasive markers of liver fibrosis. We aimed to assess the diagnostic accuracy of APRI and FIB-4 for liver fibrosis in patients with autoimmune hepatitis (AIH) using liver biopsy as the reference standard. Methods PubMed, EMBASE, Cochrane Library and Web of Science databases were searched for studies (published as of May 1st, 2021) that assessed the diagnostic performance of APRI and FIB-4 for liver fibrosis in AIH. The summary area under receiver operating characteristics curve (AUROC), sensitivity, specificity, diagnostic odds ratios were used to assess the diagnostic accuracy of APRI and FIB-4 for detecting liver fibrosis. Results Fourteen studies (including 1015 patients) were selected with 13 studies each evaluating the use of APRI and FIB-4 for detecting different stages of fibrosis in AIH. For prediction of significant fibrosis, advanced fibrosis, and cirrhosis, the summary AUROC value was 0.66 [95% confidence interval (CI): 0.61-0.70], 0.71 (95% CI: 0.67-0.75), and 0.75 (95% CI: 0.71-0.79) for APRI, and the summary AUROC value was 0.75 (95% CI: 0.71-0.79), 0.73 (95% CI: 0.69-0.77) and 0.79 (95% CI: 0.75-0.82) for FIB-4, respectively. The summary sensitivity and specificity for diagnosis of significant fibrosis, advanced fibrosis, and cirrhosis were 90% and 36%, 78% and 55%, and 77% and 61% for APRI, and 70% and 70%, 65% and 70%, and 78% and 65% for FIB-4, respectively. Conclusions APRI and FIB-4 showed suboptimal diagnostic performance for identifying liver fibrosis in AIH with mediocre sensitivity and specificity.

Abstract
Background Human leukocyte antigen (HLA)-A*03, hemochromatosis ancestral haplotype marker, was associated with greater iron overload in hemochromatosis cohorts reported before discovery of the HFE gene. We sought to learn whether an A*03-linked locus influences phenotypes in referred HFE p.C282Y homozygotes. Methods We tabulated these phenotypes in probands with p.C282Y homozygosity: age, transferrin saturation (TS), serum ferritin (SF), conditions related to iron overload, fibrosis-four variables (FIB-4) index and aspartate aminotransferase-to-platelet ratio index (APRI) predictors of severe hepatic fibrosis, and iron removed to achieve depletion (QFe/age). We analyzed phenotypes of men and women separately across three A*03 subgroups. Results There were 104 men (57.8%) and 76 women (42.2%). Mean age (SD) was 49 ± 13 y. Mean TS was 79 ± 17%. Median SF (range) was 715 µg/L (28, 6103). Related conditions included: hemochromatosis arthropathy (21.7%); type 2 diabetes (18.9%); hypogonadotropic hypogonadism (5.8% of men); cardiomyopathy (0%); and cirrhosis (10.0%). Median QFe/age was 61 mg/y (0, 714). A*03 homozygosity, heterozygosity, and no A*03 occurred in 37 (20.6%), 104 (57.8%), and 39 probands (21.7%), respectively. In men, mean TS and median SF were significantly higher in A*03 homozygotes than heterozygotes but not A*03-negative probands. In men, median APRI was significantly lower in A*03 heterozygotes than homozygotes and A*03-negative probands. No other phenotypes, including QFe/age, differed significantly across A*03 subgroups in either men or women. Conclusions Our results suggest that an A*03-linked locus does not influence phenotypes in referred HFE p.C282Y homozygotes. It is unlikely that heritable factors that modify phenotypes of p.C282Y homozygotes are linked to the hemochromatosis ancestral haplotype.

Diagnostic Value of FibroTouch and Non-invasive Fibrosis Indexes in Hepatic Fibrosis with Different Aetiologies. Dig Dis Sci 2022; 67:2627-2636.

Abstract
BACKGROUND Liver biopsy is the gold standard for staging liver fibrosis, but it has numerous drawbacks, mainly associated with bleeding and bile fistula risks. A number of non-invasive techniques have been investigated, but they all have their own disadvantages. To avoid the risks mentioned above and to improve the diagnostic value, we still need to search for a more accurate non-invasive method to evaluate the degree of liver fibrosis. AIM This study aimed to evaluate the diagnostic performance of FibroTouch versus other non-invasive fibrosis indexes in hepatic fibrosis of different aetiologies. METHODS This study retrospectively enrolled 227 patients with chronic hepatic liver disease admitted to the first hospital of Lanzhou University from 2017 to 2020. Liver biopsy was performed in all of the patients, and their biochemical indicators were all tested. Non-invasive indexes including the fibrosis index based on four factors (FIB-4), the aminotransferase-to-platelet ratio index (APRI), and the gamma-glutamyl transpeptidase-to-platelet ratio index (GPRI) were all calculated. Transient elastography was performed using FibroTouch. RESULTS The correlation between FibroTouch and the pathology of liver fibrosis was significantly higher than that between the non-invasive fibrosis indexes and the biopsy results (r = 0.771, p < 0.05). The area under the receiver operating curve (AUC) of FibroTouch was significantly higher than that of FIB-4, APRI, and GPRI for the diagnosis of significant fibrosis (≥ S2 fibrosis stage), advanced fibrosis (≥ S3 fibrosis stage), and cirrhosis (= S4 fibrosis stage) (p < 0.05). The patients were grouped according to different aetiologies. The diagnostic value of FibroTouch had much higher credibility in different fibrosis stages for different causes compared with other non-invasive indexes. The AUC of FibroTouch showed both higher specificity and higher sensitivity than FIB-4, APRI, and GPRI for different liver fibrosis stages with different aetiologies. CONCLUSIONS FibroTouch demonstrates the highest diagnostic value for liver fibrosis and cirrhosis among non-invasive methods, showing better results than FIB-4, APRI, and GPRI, and surpassed only by liver biopsy. FibroTouch is reliable in assessing liver fibrosis with different aetiologies.

Abstract
Over the last two decades, there have been tremendous advances in the non-invasive diagnosis and risk stratification of chronic liver diseases (CLDs). Non-invasive approaches are based on the quantification of biomarkers in serum samples or on the measurement of liver stiffness, using either ultrasound- or magnetic resonance-based elastography techniques. The fibrosis-4 index (non-patented) and enhanced liver fibrosis test (patented) are the most widely adopted serum markers, whereas vibration-controlled transient elastography is the most widely adopted elastography technique. In this review, we discuss the role of non-invasive tests in the current era, as well as their accuracy and how their use in clinical practice has changed the practice of hepatology, including identification of early cirrhosis in patients with risk factors for CLD, diagnosis of portal hypertension, establishing prognosis in compensated cirrhosis, guiding antiviral treatment, and screening for fibrosis and cirrhosis in primary care.

Abstract
BACKGROUND Fatty liver disease and fibrosis are common in patients with type 2 diabetes mellitus (T2DM). Recently published European Association for the Study of the Liver guidelines have suggested screening such patients using liver stiffness measurement (LSM) or fibrosis-4 index (FIB-4) to exclude advanced fibrosis. AIMS We initiated a screening programme at the diabetes out-patient clinic to assess the reliability of the suggested approaches and resulting referrals. METHODS In this prospective study, consecutive patients attending for T2DM review at an Irish level 3 (district general) hospital between September and November 2021 were screened for liver fibrosis using LSM and had their FIB-4 calculated. The first 100 patients with valid LSM measurements were included in the analysis. RESULTS Referral rates to the hepatology clinic varied by modality used. If FIB-4 ≥ 1.3 criterion was used, the referral rate to the hepatology clinic was 45%; using LSM < 8 kPa to rule out advanced fibrosis resulted in 34% referral rate; using LSM ≥ 10 kPa to suggest probable compensated advanced chronic liver disease reduced referral rates to 15%. Combining FIB-4 with LSM in a two-step algorithm led to missed potentially significant liver disease in large numbers. 47% patients with LSM ≥ 8 kPa and 33% with LSM ≥ 10 kPa had FIB-4 < 1.3. CONCLUSIONS Screening of patients with T2DM using LSM alone rather than FIB-4 leads to reduced numbers of, and more appropriate, referrals to the hepatology clinic. Shifting from an exclusion (LSM < 8 kPa) to an inclusion based (LSM ≥ 10 kPa) approach may lessen the potential of screening to overwhelm hepatology services.

Non-Invasive Tests of Liver Fibrosis Help in Predicting the Development of Hepatocellular Carcinoma among Patients with NAFLD. J Clin Med 2022; 11:jcm11092466.

Abstract
Background: The potential role of non-invasive tests (NITs) for liver fibrosis for hepatocellular carcinoma (HCC) prediction remains poorly known. Methods: Retrospective analysis of a NAFLD cohort from a single university hospital in Barcelona, Spain. Incidence rates and cumulative incidence for the overall cohort, as well as cirrhotic and non-cirrhotic patients were calculated. Logistic regression analyses were carried out to investigate risk factors of HCC. Results: From the entire cohort of 1040 patients, 996 patients (95.8%) were analyzed, in whom 35 cases of HCC were detected, of which 26 (72.4%) HCC incident cases were newly diagnosed during a median follow-up of 2.5 (1.9−3.6) years. Two-hundred and thirty-one (23.2%) were cirrhotic at baseline. With the exception of 2 (7.7%) cases of HCC, the rest were diagnosed in cirrhotic patients. Overall HCC cumulative incidence was 9.49 (95% CI 6.4−13.9) per 1000 person-years. The incidence rate for cirrhotic patients was 41.2 (95% CI 27.6−61.6) per 1000 person-years and 0.93 (95% CI 0.23−3.7) per 1000 person-years for patients without cirrhosis. Overall mortality was significantly higher amongst patients with HCC (4.4% vs. 30.8%, p < 0.001). In patients with available liver biopsy (n = 249, 25%), advanced fibrosis (F3−F4) was significantly associated with higher HCC incidence, but not steatosis, lobular inflammation, nor ballooning. In the overall cohort, FIB-4 ≥1.3 (HR 8.46, 95% CI 1.06−67.4, p = 0.044) and older age (HR 1.06, 95% CI 1.01−1.11, p = 0.025) were associated with increasing risk of HCC over time, whereas in cirrhotic patients predictors of HCC included decreasing values of albumin (HR 0.34, 95% CI 0.13−0.87, p = 0.024), platelets (HR 0.98, 95% CI 0.98−0.99, p = 0.001), and increasing values of liver stiffness (HR 1.03, 95% CI 1.00−1.06, p = 0.016). Conclusions: In a Spanish cohort of NAFLD patients, HCC was rare in non-cirrhotic patients. NITs might play a relevant role at predicting HCC.

Schöler D, Kostev K, Demir M, Luedde M, Konrad M, Luedde T, Roderburg C, Loosen SH. An Elevated FIB-4 Score Is Associated with an Increased Incidence of Depression among Outpatients in Germany. J Clin Med 2022; 11:jcm11082214. [PMID: 35456304 PMCID: PMC9032098 DOI: 10.3390/jcm11082214] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/12/2022] [Accepted: 04/12/2022] [Indexed: 12/26/2022] Open
Abstract
Background: Liver disease and depression are known to be closely associated. Non-invasive tests (NIT), such as the FIB-4 score, have been recommended by different guidelines to rule out advanced fibrosis and to stratify the risk of liver-related outcomes in patients with chronic liver diseases. However, the predictive value of an elevated FIB-4 score regarding the development of depression and/or anxiety disorders among the general population is unknown. Methods: By using the Disease Analyzer database (IQVIA), which compiles diagnoses and laboratory values as well as basic medical and demographic data of patients followed in general practices in Germany, we identified 370,756 patients with available lab values for FIB-4 score calculation between 2005 and 2019. Patients with an FIB-4 score < 2 were matched 1:1 to patients with an FIB-4 index ≥ 2 by age, sex and yearly consultation frequency. Results: In regression analysis, the incidence rate ratio (IRR) of depression was significantly higher among patients with an FIB-4 score ≥ 2.0 compared to patients with a lower FIB-4 score <2.0 (IRR: 1.12, p < 0.001). This association was significant for both female (IRR: 1.10, p = 0.004) and male (IRR: 1.15, p < 0.001) patients and strongest in the age groups ≤50 years (IRR: 1.42, p < 0.001) and 51-60 years (IRR: 1.34, p < 0.001). There was no significant association between an elevated FIB-4 score ≥ 2.0 and the incidence of depression among patients aged 60 years and older. There was no significant increase in the IRR of anxiety disorders for patients with high or low FIB-4 scores. Conclusion: Our study suggests a previously unknown association between an elevated FIB-4 score and an increased incidence of depression. This finding suggests that the FIB-4 score is not only a valuable tool for the prediction of liver-specific endpoints but also may be of relevance for the prediction of extrahepatic comorbidities, which in turn may argue for clinical screening programs in patients with an elevated FIB-4.

A structurally engineered fatty acid, icosabutate, suppresses liver inflammation and fibrosis in NASH. J Hepatol 2022; 76:800-811. [PMID: 34915054 DOI: 10.1016/j.jhep.2021.12.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 12/01/2021] [Accepted: 12/02/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND & AIMS Although long-chain omega-3 fatty acids (LCn-3FAs) regulate inflammatory pathways of relevance to non-alcoholic steatohepatitis (NASH), their susceptibility to peroxidation may limit their therapeutic potential. We compared the metabolism of eicosapentaenoic acid (EPA) with an engineered EPA derivative (icosabutate) in human hepatocytes in vitro and their effects on hepatic glutathione metabolism, oxidised lipids, inflammation, and fibrosis in a dietary mouse model of NASH, and in patients prone to fatty liver disease. METHODS Oxidation rates and cellular partitioning of EPA and icosabutate were compared in primary human hepatocytes. Comparative effects of delayed treatment with either low- (56 mg/kg) or high-dose (112 mg/kg) icosabutate were compared with EPA (91 mg/kg) or a glucagon-like peptide 1 receptor agonist in a choline-deficient (CD), L-amino acid-defined NASH mouse model. To assess the translational potential of these findings, effects on elevated liver enzymes and fibrosis-4 (FIB-4) score were assessed in overweight, hyperlipidaemic patients at an increased risk of NASH. RESULTS In contrast to EPA, icosabutate resisted oxidation and incorporation into hepatocytes. Icosabutate also reduced inflammation and fibrosis in conjunction with a reversal of CD diet-induced changes in the hepatic lipidome. EPA had minimal effect on any parameter and even worsened fibrosis in association with depletion of hepatic glutathione. In dyslipidaemic patients at risk of NASH, icosabutate rapidly normalised elevated plasma ALT, GGT and AST and reduced FIB-4 in patients with elevated ALT and/or AST. CONCLUSION Icosabutate does not accumulate in hepatocytes and confers beneficial effects on hepatic oxidative stress, inflammation and fibrosis in mice. In conjunction with reductions in markers of liver injury in hyperlipidaemic patients, these findings suggest that structural engineering of LCn-3FAs offers a novel approach for the treatment of NASH. LAY SUMMARY Long-chain omega-3 fatty acids are involved in multiple pathways regulating hepatic inflammation and fibrosis, but their susceptibility to peroxidation and use as an energy source may limit their clinical efficacy. Herein, we show that a structurally modified omega-3 fatty acid, icosabutate, overcame these challenges and had markedly improved antifibrotic efficacy in a mouse model of non-alcoholic steatohepatitis. A hepatoprotective effect of icosabutate was also observed in patients with elevated circulating lipids, in whom it led to rapid reductions in markers of liver injury.

Abstract
AIM Accurate detection of the hepatic fibrosis stage is essential to estimate the outcome of patients with non-alcoholic fatty liver disease (NAFLD). Many formulas, biomarkers, and imaging tests are being developed to predict advanced liver fibrosis without performing a liver biopsy. However, these tests do not have high efficiency in detecting early-stage hepatic fibrosis. Therefore, we aimed to detect the presence of hepatic fibrosis (≥F1) merely by using only standard clinical markers. METHODS A total of 436 patients with NAFLD who underwent liver biopsy were retrospectively enrolled as the discovery cohort (316 patients) and the validation cohort (120 patients). Liver biopsy and laboratory data were matched to extract simple parameters for identifying ≥F1. RESULTS We developed a novel simplified ≥F1 detecting system, designated as 2-Step PLT16-AST44 method, where (1) PLT of 16 × 104 /μl or less, or (2) PLT greater than 16 × 104 /μl and AST greater than 44 U/L is determined as having ≥F1 fibrosis. The 2-Step PLT16-AST44 method had a sensitivity of 68%, a specificity of 90%, a positive predictive value (PPV) of 97%, a negative predictive value (NPV) of 40%, and an accuracy of 72% to detect ≥F1 fibrosis in the discovery cohort. Validation studies further supported these results. Despite its simplicity, the 2-Step PLT16-AST44 method's power to detect ≥F1 fibrosis in total NAFLD patients was comparable to hyaluronic acid, type 4 collagen 7S, FIB-4, and APRI. CONCLUSIONS We propose the 2-Step PLT16-AST44 method as a simple and beneficial early-stage hepatic fibrosis detection system.

Abstract
BACKGROUND & AIMS Non-alcoholic steatohepatitis (NASH) is a chronic, progressive fibrotic liver disease that can lead to cirrhosis. While liver biopsy is considered the reference standard for the histologic diagnosis of NASH and staging of fibrosis, its use in clinical practice is limited. Non-invasive tests (NITs) are increasingly being used to identify and stage liver fibrosis in patients with NASH, and several can assess liver-related outcomes. We report changes in various NITs in patients treated with obeticholic acid (OCA) or placebo in the phase III REGENERATE study. METHODS Patients with NASH and fibrosis stage F2 or F3 (n = 931) were randomized (1:1:1) to receive placebo, OCA 10 mg, or OCA 25 mg once daily. Various NITs based on clinical chemistry and/or imaging were evaluated at baseline and throughout the study. RESULTS Rapid, sustained reductions from baseline in alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase levels, as well as in Fibrosis-4 (FIB-4), FibroTest, FibroMeter, and FibroScan-AST scores were observed in OCA-treated vs. placebo-treated patients. Reduction in liver stiffness by vibration-controlled transient elastography was observed in the OCA 25 mg group vs. the placebo group at Month 18. NIT changes were associated with shifts in histologic fibrosis stage. The greatest improvements were observed in patients with ≥1-stage fibrosis improvement; however, improvements in ALT, AST, FIB-4, and FibroTest were also observed in OCA-treated patients whose histologic fibrosis remained stable. CONCLUSIONS Based on the REGENERATE Month 18 interim analysis, rapid and sustained improvements in various NITs were observed with OCA treatment. Dynamic changes in selected NITs separated histologic responders from non-responders. These results suggest that NITs may be useful in assessing histologic response to OCA therapy. CLINICALTRIALS. GOV NUMBER NCT02548351 LAY SUMMARY: Non-alcoholic steatohepatitis (NASH) is a chronic, progressive liver disease that can lead to cirrhosis. To diagnose and assess liver fibrosis (scarring) in patients with NASH, non-invasive tests (NITs) are increasingly being used rather than liver biopsy, which is invasive, expensive, and can be risky. In the REGENERATE study, which is evaluating the effects of obeticholic acid vs. placebo in patients with NASH, various NITs were also evaluated. This analysis shows that improvements in levels of certain blood components, as well as favorable results of ultrasound imaging and proprietary tests of liver function, were associated with improvements in liver fibrosis after treatment with obeticholic acid, suggesting that NITs may be useful alternatives to liver biopsy in assessing NASH patients' response to therapy.

Abstract
PURPOSE Obstructive Sleep Apnea (OSA) is associated with the presence and severity of Non-Alcoholic Fatty Liver Disease (NAFLD). We aimed to investigate the relationship between the severity of OSA and NAFLD and to recognize a polysomnographic parameter correlated with progression of fibrosis, determined by a non-invasive score of liver fibrosis, FIBrosis-4 index (FIB-4), in patients affected by severe obesity and OSA. METHODS We enrolled 334 patients (Body Mass Index, BMI 44.78 ± 8.99 kg/m2), divided into classes according to severity of OSA evaluated with Apnea Hypopnea Index (AHI): OSAS 0 or absent (17%), mild OSA (26%), moderate OSA (20%), severe OSAS (37%). We studied anthropometric, polysomnographic, biochemical data and FIB-4. A multiple regression model was computed to identify a polysomnographic independent predictor of FIB-4 among those parameters previously simple correlated with FIB-4. RESULTS The severity of OSA was associated with a decrease in High-Density Lipoprotein-cholesterol (HDL) and an increase in BMI, triglycerides, Homeostasis model assessment insulin-resistance index (HOMA), transaminases and FIB-4. FIB-4 correlated with sex, age, BMI, AHI, mean percentage oxyhaemoglobin (meanSaO2%), number of desaturations, platelets, transaminases, HDL, triglycerides and HOMA. The only variables independently related to FIB-4 were sex, BMI, triglycerides and meanSpO2 (r = 0.47, AdjRsqr = 0.197). CONCLUSION MeanSpO2% represented an independent determinant for the worsening of FIB-4 in patients with severe obesity and OSA. Hence, it could hypothesize a clinical role of meanSaO2% in recognizing patients with obesity and OSA and higher risk of developing advanced fibrosis and, thus, to undergo further investigation. LEVEL III Evidence obtained from well-designed cohort analytic studies.

A Prospective Pilot Study. J Clin Exp Hepatol 2022; 12:1083-1090. [PMID: 35814506 PMCID: PMC9257884 DOI: 10.1016/j.jceh.2022.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 01/19/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND AND AIMS Erectile dysfunction (ED) is common in patients with compensated cirrhosis but its impact on the quality of life (QOL) is usually overlooked. This study aimed at determining the frequency of ED in male patients with compensated chronic liver disease (CLD), assessing their QOL and the response to treatment with tadalafil. A secondary aim was to assess the effect of the tadalafil therapy on liver fibrosis, if any. METHODS Consecutive patients with compensated CLD and advanced liver fibrosis were screened at the baseline with the International Index of Erectile Function-5 (IIEF-5), QOL questionnaire (WHOQOL-BREF), liver stiffness measurements (LSM) made with Fibroscan™ (Echosens, France), and fibrosis index based on 4 factors (FIB-4) scores. Patients with ED meeting eligibility criteria were prescribed PDE5 inhibitor tadalafil 20 mg on alternate days. During the follow-up, IIEF-5, LSM, and FIB-4 were monitored after 3 and 6 months while the WHOQOL-BREF questionnaire was administered at the baseline and at 6 months. RESULTS Among 89 patients with CLD and advanced liver fibrosis, ED was present in 43 (48%) and tadalafil was prescribed to 34 patients (38%) meeting exclusion and inclusion criteria. At 3 months follow-up, the mean IIEF 5 score increased from 15.57 ± 4 to 20.78 ± 3.6, (P = 0.0001) and the improvement persisted at 6 months (IIEF-5 score 21.87 ± 2.2; P = 0.12). The physical, social relationships, and environment domains in the WHOQOL-BREF questionnaire showed significant improvement at six months (P < 0.05) but not the psychological domain (P = ns). From a baseline value of 12.69 ± 3.1 kPa, the mean LSM decreased to 11.37 ± 3.9 kPa, (P = 0.02) after 3 months on tadalafil. After 6 months, the LSM further decreased from 11 ± 0.9 to 8.2 ± 3.2 kPa (P = 0.034). FIB-4 values showed a decline from the baseline at 3 months, from 1.52 ± 0.58 to 1.32 ± 0.55, P < 0.05 and at 6 months, from 1.25 ± 0.53 to 0.97 ± 0.36, P > 0.05. The CAP values did not show any significant change. There was an insignificant decline in the SGOT and SGPT levels (P > 0.05) with no significant change in CTP or MELD scores. CONCLUSIONS In the short term, tadalafil improves ED and QOL in patients with CLD and advanced liver fibrosis. It may also reduce liver fibrosis in them. Further studies that include liver histology are needed to confirm this preliminary observation of a possible antifibrotic effect.

Abstract
BACKGROUND AND AIM Antiviral therapy (AVT) induces fibrosis regression in patients with chronic hepatitis B. We investigated long-term effects of entecavir (ETV) versus tenofovir (TDF) on fibrotic burden. METHODS Treatment-naïve chronic hepatitis B patients who had begun ETV or TDF were recruited from four tertiary hospitals. The aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis index based on four factors (FIB-4) were used to determine fibrotic burden. RESULTS In the entire population (n = 3277), although patients treated with ETV had higher baseline APRI (1.71 vs 1.07, P < 0.001) and FIB-4 (3.60 vs 2.80, P < 0.001) than those treated with TDF, significant fibrosis regression was identified during 6 years of AVT in both ETV (APRI, mean 1.71 → 0.48, P < 0.001; FIB-4, mean 3.60 → 2.21, P < 0.001) and TDF groups (APRI, mean 1.07 → 0.43, P < 0.001; FIB-4, mean 2.80 → 2.19, P < 0.001). In patients without cirrhosis (n = 2366), baseline APRI was significantly higher in ETV group than in TDF group (1.72 vs 0.97, P < 0.001); however, they became similar after 6 months. Similarly, baseline FIB-4 was significantly higher in ETV group than in TDF group (3.25 vs 2.35, P < 0.001), but became similar from 4 to 6 years. In patients with cirrhosis (n = 911), baseline APRI (1.70 vs 1.34, P < 0.001) and FIB-4 (4.62 vs 3.91, P = 0.005) were higher in ETV group than in TDF, however, both parameters became statistically similar from 6 months to 6 years. CONCLUSION Significant regression of APRI and FIB-4 was observed during long-term ETV and TDF treatment. Despite higher baseline fibrotic burden in ETV group, fibrotic burden between the groups eventually converged through significant fibrosis regression after 1 to 4 years of AVT.

Abstract
BACKGROUND Some young adults with chronic hepatitis B virus (HBV) infection might be at high risk for hepatocellular carcinoma (HCC), enough to justify regular HCC surveillance despite the young age of the patients. However, ways to identify at-risk individuals who may benefit from HCC surveillance need further evaluations. METHODS A hospital-based retrospective cohort of 2757 chronic HBV mono-infected young adults (median age: 34 years, males 66%) were analyzed. The primary outcome was young-onset HCC, defined as a diagnosis made under 40 years of age. We calculated the HCC incidence/1000 person-years in the overall cohort and pre-defined subgroups of patients assessed the independent risk factors that can be used to identify surveillance targets. RESULTS The HCC incidence was low (2.55/1000 person-years) in the overall cohort. However, the HCC incidence varied widely according to baseline characteristics: lowest among young adults with FIB-4 ≤ 0.70 (0.17/1000 person-years) and highest in young adults with radiological cirrhosis (30.7/1000 person-years). In multivariable analysis, radiological cirrhosis, the FIB-4 index, and serum HBV DNA level were independent factors associated with HCC development at a young age. Performance for prediction of young-onset HCC in radiological cirrhotic patients showed the highest specificity but sensitivity was <70%. Combination with FIB-4 index and HBV DNA levels increased sensitivity to 90%. CONCLUSION Risk stratification using FIB-4 index, HBV DNA levels, and either combining radiological cirrhosis or gender and AFP levels would be helpful to stratify young patients who would and would not benefit from regular HCC surveillance.

Abstract
Liver involvement in Coronavirus Disease 2019 (COVID-19) has been widely documented. However, data regarding liver-related prognosis are scarce and heterogeneous. The current study aims to evaluate the role of abnormal liver tests and incidental elevations of non-invasive fibrosis estimators on the prognosis of hospitalized COVID-19 patients. We conducted a retrospective cohort study to investigate the impact of elevated liver tests, non-invasive fibrosis estimators (the Fibrosis-4 (FIB-4), Forns, APRI scores, and aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio), and the presence of computed tomography (CT)-documented liver steatosis on mortality in patients with moderate and severe COVID-19, with no prior liver disease history. A total of 370 consecutive patients were included, of which 289 patients (72.9%) had abnormal liver biochemistry on admission. Non-survivors had significantly higher FIB-4, Forns, APRI scores, and a higher AST/ALT ratio. On multivariate analysis, severe FIB-4 (exceeding 3.25) and elevated AST were independently associated with mortality. Severe FIB-4 had an area under the receiver operating characteristic (AUROC) of 0.73 for predicting survival. The presence of steatosis was not associated with a worse outcome. Patients with abnormal liver biochemistry on arrival might be susceptible to a worse disease outcome. An FIB-4 score above the threshold of 3.25, suggestive of the presence of fibrosis, is associated with higher mortality in hospitalized COVID-19 patients.
