Multiparametric liver assessment in patients successfully treated for hepatitis C: a 4-year follow-up.

BACKGROUND: Hepatitis C virus (HCV) is a major cause of chronic liver disease, in which liver stiffness increases. Liver stiffness measurements (LSM) are therefore essential in diagnosing liver diseases and predicting disease development. The study objective was to perform a comprehensive prospective assessment of the liver before, after and 4 years after treatment for HCV, including an assessment of the long-term outcome of fibrosis, steatosis and inflammation. METHODS AND FINDINGS: Patients eligible for HCV treatment were included prospectively in 2018 (n = 47). Liver stiffness was measured using transient elastography and 2D shear-wave elastography (SWE). Blood tests, B-mode ultrasound (US) and SWE, were performed before, after (end of treatment [EOT]), 3 months after (EOT3) and 4 years after treatment (4Y). At the final visit, we added attenuation imaging and shear-wave dispersion slope (SWDS) measurements to assess steatosis and inflammation. Three months after treatment, the sustained virologic response rate was 93%. The median liver stiffness for baseline, EOT, EOT3 and 4Y was 8.1, 5.9, 5.6 and 6.3 kPa, respectively. There was a significant reduction in liver stiffness from baseline to EOT, and from EOT to EOT3. After 4 years, the mean attenuation coefficient (AC) was 0.58 dB/cm/MHz, and the mean SWDS value was 14.3 (m/s)/kHz. CONCLUSION: The treatment for HCV was highly effective. Measurements of liver stiffness decreased significantly after treatment and remained low after 4 years. AC measurements indicated low levels of liver steatosis. Shear-wave dispersion values indicated inflammation of the liver, but the clinical implication is undetermined and should be explored in larger studies.Clinicaltrials.gov: NCT03434470. ABBREVIATIONS: AC: attenuation coefficient; APRI: aspartate aminotransferase to platelet ratio index; ATI: attenuation imaging; cACLD: compensated advanced chronic liver disease; CAP: controlled attenuation parameter; FIB-4: Fibrosis-4 Index for liver fibrosis; HCC: hepatocellular carcinoma; LSM: liver stiffness measurement; NAFLD: non-alcoholic fatty liver disease; NASH: non-alcoholic steatohepatitis; SWDS: shear-wave dispersion slope; SWE: shear-wave elastography; US: ultrasound.

Non-invasive assessment of severe liver fibrosis in patients with Fontan-associated liver disease: The VALDIG-EASL FONLIVER cohort.

BACKGROUND & AIMS: Fontan-type surgery is used as a palliation for congenital heart disease with univentricular physiology but may, in the long term, lead to advanced chronic liver disease. This study assessed the accuracy of conventional non-invasive models in assessing liver fibrosis and introduces a new risk score employing non-invasive tools. METHODS: A prospective, cross-sectional, observational study was conducted across five European centers and encompassing all consecutive adult patients with Fontan circulation, liver biopsy and non-invasive tests (elastography, APRI, FIB-4, Fibrosis score, Doha, GUCI, and AAR). The primary outcome was the identification of severe liver fibrosis on biopsy. Multivariable logistic regression identified non-invasive predictors of severe fibrosis, leading to the development and internal validation of a new scoring model named the FonLiver risk score. RESULTS: In total, 217 patients (mean [standard deviation] age, 27.9 [8.9] years; 50.7% males) were included. Severe liver fibrosis was present in 47.9% (95% CI 41.2%-54.5%) and correlated with a lower functional class, protein-losing enteropathy, and compromised cardiopulmonary and systemic hemodynamics. The final FonLiver risk score incorporated liver stiffness measurement using transient elastography and platelet count and demonstrated strong discrimination and calibration (area under the receiver operating curve [AUROC] of 0.81). The FonLiver risk score outperformed conventional prediction models (APRI, FIB-4, Fibrosis score, Doha, GUCI, and AAR), which all exhibited worse performance in our cohort (AUROC < 0.70 for all). CONCLUSION: Severe liver fibrosis is prevalent in adults following Fontan-type palliation and can be effectively estimated using with the novel FonLiver risk score. This scoring system can be easily incorporated into the routine assessment of patients with Fontan circulation.

Performance of spleen stiffness measurement by 100-Hz vibration-controlled transient elastography, liver stiffness, APRI score and their combination for predicting oesophageal varices in liver cirrhosis.

BACKGROUND: Oesophageal varices (EV) rupture remains one of the most severe complications of cirrhosis. As the gold standard to predict this accident, esophagogastroduodenoscopy (EGD) itself also has a weakness. Not all patients are convenient with this modality in clinical practice apart from the risk and cost burden. Hence, the search for other non-invasive modalities with high accuracy is still noteworthy. Among them, spleen stiffness measurement (SSM) with 100 Hz probe, liver stiffness measurement (LSM), and the aspartate amino transferase to platelet ratio index (APRI) score became popular and intensively studied with good accuracy, but the results remain conflicting. This study aims to investigate the performance of SSM, LSM, APRI score, and their combination especially as a screening tool for predicting EV in liver cirrhosis patients. METHODS: In this cross-sectional study, we included 141 patients with liver cirrhosis who had undergone endoscopy, SSM, LSM, and APRI score calculation between January and March 2023 were enrolled. Diagnostic accuracy was assessed by the area under the receiver-operator curve (AUC). Transient elastography (TE) measurement was performed using a spleen-dedicated FibroScan with a 100-Hz probe. RESULTS: Of the 141 patients, the most common aetiology was hepatitis B in 71 patients (50.4 %). EV were found in 116 patients. Using the AUC, SSM at a cutoff of 40 kPa had the best performance with an AUC of 0.892 (CI 95 %: 0.814-0.969, p <0.0001), with sensitivity 88.79 % and specificity 80 %). Meanwhile, LSM and APRI score had an AUC of 0.832 (CI 95 %: 0.742-0.922, p <0.0001) and 0.780 (CI 95 %: 0.660-0.900, p <0.0001), respectively. The combination of all measurement tools did not show better performance than SSM alone with an AUC of 0.892 (CI 95 %: 0.802-0.982, P <0.0001) CONCLUSION: SSM provides better performance than LSM and APRI scores for predicting EV. Performance of SSM alone is non-inferior compare to multiple diagnostic tools combined.

Effect of Pemafibrate on the Lipid Profile, Liver Function, and Liver Fibrosis Among Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are prevalent conditions linked to obesity and metabolic disturbances, with potential complications such as cirrhosis and cardiovascular risks. This systematic review and meta-analysis aimed to evaluate the efficacy of pemafibrate, a drug targeting fat and sugar metabolism genes, in treating patients with MASLD/MASH. Methods: Databases such as MEDLINE, Web of Science, Cochrane Library, and Scopus were searched until September 2023 to identify relevant studies. Selected studies underwent a thorough quality assessment using tools like Risk of Bias 2 tool (ROB-2) and the National Institutes of Health (NIH) Quality Assessment Tools. Comprehensive meta-analysis software was used for statistical evaluations, with a focus on lipid profiles, liver function tests, and fibrosis measurements. Results: A total of 13 studies were included; 10 of them were included in the quantitative analysis. Our findings showed that pemafibrate significantly decreased low-density lipoprotein cholesterol (LDL-C) (effect size (ES) = -9.61 mg/dL, 95% confidence interval (CI): -14.15 to -5.08), increased high-density lipoprotein cholesterol (HDL-C) (ES = 3.15 mg/dL, 95% CI: 1.53 to 4.78), and reduced triglycerides (TG) (ES = -85.98 mg/dL, 95% CI: -96.61 to -75.36). Additionally, pemafibrate showed a marked reduction in liver enzyme levels, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP), with significant effect sizes and P values. For liver stiffness outcomes, pemafibrate decreased AST to platelet ratio index (APRI) (ES = -0.180, 95% CI: -0.221 to -0.138). Conclusions: Pemafibrate, with its enhanced efficacy and safety profile, presents as a pivotal agent in MASLD/MASH treatment. Its lipid-regulating properties, coupled with its beneficial effects on liver inflammation markers, position it as a potentially invaluable therapeutic option.

Dynamic Changes in ELF Score Predict Hepatocellular Carcinoma in Chronic Hepatitis B Patients Receiving Antiviral Treatment.

Enhanced liver fibrosis (ELF) score is a noninvasive assessment for liver fibrosis. We aimed to evaluate the performance of changes in ELF score 3 years apart in combination with liver stiffness measurement (LSM)-hepatocellular carcinoma (HCC) score to predict HCC in chronic hepatitis B (CHB) patients. This is a prospective cohort study. Patients who underwent transient elastography (TE) examinations and at intermediate or high risk of HCC defined by LSM-HCC score were invited to repeat the examination about 3 years later. Their serum samples at these two time points were retrieved to assess the ELF score changes. The primary endpoint was HCC. There were 445 CHB patients (males: 73.9%; mean age: 51.6 ± 10.3 years) who received two TE examinations and ELF scores. Among them, 252 (56.6%) and 193 (43.4%) patients were at intermediate and high HCC risk at first assessment defined by LSM-HCC score, respectively. Kaplan-Meier analysis showed that the changes in ELF score could stratify the HCC risk in both intermediate- and high-risk patients defined by LSM-HCC score (p < 0.001 for intermediate-risk group; p = 0.011 for high-risk group). Patients remained having mild or moderate fibrosis at both assessments had the lowest risk of HCC (4.0%), followed by patients with fibrosis regressed (11.3%; p = 0.014) during a mean follow-up of 163 months. Patients remained having or progressed to severe fibrosis were at highest risk of HCC (>20%). Consistent findings were demonstrated in patients at both intermediate and high risk of HCC defined by LSM-HCC score. Dynamic changes in ELF score provided additional value to LSM-HCC score for stratifying HCC risk in CHB patients.

Effect of Indo-Mediterranean diet versus calorie-restricted diet in children with non-alcoholic fatty liver disease: A pilot randomized control trial.

BACKGROUND: Dietary interventions and increased physical activity are the cornerstones for management of the paediatric non-alcoholic fatty liver disease (NAFLD). Though, no specific diet has been proven superior, Indo-Mediterranean diet (IMD) has shown promise in adult literature. Thus, we aimed to compare the effect of IMD and a standard calorie-restricted diet (CRD) in Indian overweight children and adolescents with biopsy-proven NAFLD. METHODS: Thirty-nine consecutive biopsy-proven NAFLD children between the ages of 8 and 18 years were randomized into either IMD or CRD for 180 days, and various parameters were evaluated at baseline and then after 180 days (NCT05073588). RESULTS: A total of 34 subjects (18 in IMD and 16 in CRD group) completed the study. There was a significantly higher decrease in controlled attenuation parameter (CAP) values (as a marker of hepatic steatosis; on transient elastography) (95% CI: 4.2-73.4, p = 0.042), weight (95% CI: 0.75-5.5, p = 0.046) and body mass index (BMI) (95% CI: 0.21-2.05, p = 0.014) (but not in Pediatric NAFLD Fibrosis Index or PNFI; as a marker of hepatic fibrosis) in IMD group compared to the CRD group. Liver stiffness measurement, serum cholesterol and low-density lipoprotein levels and HOMA-IR decreased only in the IMD group (p < 0.001). Our statistical model showed that delta-Weight was the only independent variable associated with delta-CAP. CONCLUSION: Both IMD and CRD can improve the various anthropometric, clinical, imaging and biochemical parameters but IMD was superior to CRD in terms of reducing CAP values and weight/BMI over 180 days in overweight/obese NAFLD children.

Alpha-1 antitrypsin deficiency and Pi*Z allele as important co-factors in the development of liver fibrosis.

BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a codominant autosomal hereditary condition that predisposes patients to the development of lung and/or liver disease, and Pi*Z allele is the most clinically relevant mutation. AIM: To evaluate the impact of clinical parameters and AATD phenotypes, particularly the Pi*Z allele, in liver fibrosis. METHODS: Cross-sectional cohort study including consecutive patients with AATD followed in Pulmonology or Hepatology consultation. RESULTS: Included 69 patients, 49.3% had Pi*MZ phenotype and 10.1% Pi*ZZ. An age ≥ 55 years, age at diagnosis ≥ 41 years and AAT at diagnosis < 77 mg/dL predicted a nonalcoholic fatty liver disease fibrosis score (NFS) not excluding advanced fibrosis [area under the curve (AUC) = 0.840, P < 0.001; AUC = 0.836, P < 0.001; AUC = 0.681, P = 0.025]. An age ≥ 50 years and age at diagnosis ≥ 41 years predicted a fibrosis-4 index of moderate to advanced fibrosis (AUC = 0.831, P < 0.001; AUC = 0.795, P < 0.001). Patients with hypertension, type 2 diabetes mellitus (DM), dyslipidaemia, metabolic syndrome, and regular alcohol consumption were more likely to have a NFS not excluding advanced fibrosis (P < 0.001, P = 0.002, P = 0.008, P < 0.001, P = 0.033). Patients with at least one Pi*Z allele and type 2 DM were 8 times more likely to have liver stiffness measurement ≥ 7.1 kPa (P = 0.040). CONCLUSION: Risk factors for liver disease in AATD included an age ≥ 50 years, age at diagnosis ≥ 41 years, metabolic risk factors, regular alcohol consumption, at least one Pi*Z allele, and AAT value at diagnosis < 77 mg/dL. We created an algorithm for liver disease screening in AATD patients to use in primary care, selecting those to be referred to Hepatology consultation.

Splenic Stiffness Measurement Combined With Liver Stiffness Measurement Compared With Baveno VII Criteria in Predicting the Presence of Oesophageal and Gastric Varices in Patients With Compensated Advanced Liver Cell Disease (cALCD).

INTRODUCTION: Liver stiffness measurement (LSM) using vibration-controlled transient elastography (VCTE) is being increasingly used as a screening tool to predict varices. Our aim was to test the utility of Baveno VII criteria and other combinations of LSM, platelet count (PC), and splenic stiffness measurement (SSM) to predict the presence of varices in a cohort of Sri Lankan patients with compensated advanced liver cell disease (cALCD). METHODS: Consecutive patients with newly diagnosed Child-Pugh class A cALCD (non-viral, BMI<30) were recruited prospectively. They underwent gastroscopy. LSM and SSM were taken using vibration-controlled transient elastography (VCTE) (Echosens FibroScan 502 Touch; Echosens SA, Paris, France) by a single operator who was unaware of endoscopy findings. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of different Baveno VII criteria to predict the varices and different combinations of LSM, SSM, and PC were also explored. RESULTS: One hundred and seventy-four individuals were recruited. The mean age was 61.4 ((95% CI: 59.7-62.8) years. A total of 110 individuals were males, and 106 had varices. Our results indicated that the three Baveno VII criteria had sensitivities of 61%, 63%, and 42%, and specificities of 79%, 77%, and 87% to predict varices. SSM>30kPa alone and in combination with LSM>15kPa had sensitivities of 81 and 75%, specificities of 72 and 83%, PPVs of 82 and 87%, NPVs of 71% and 67%, and accuracies of 78 and 78%, respectively, to predict varices. CONCLUSION: Baveno VII criteria had a low sensitivity but high specificity in predicting the presence of varices. However, SSM>30kPa alone or in combination with LSM>15kPa had better sensitivity, specificity, PPV, NPV, and accuracy in predicting varices.

Diagnostic performance of liver stiffness as marker of liver involvement in systemic immunoglobulin light chain (AL) amyloidosis.

OBJECTIVE: To investigate the diagnostic performance of liver stiffness for detecting liver involvement in immunoglobulin light chain (AL) amyloidosis. METHODS: Liver stiffness was measured using transient elastography in 71 patients with systemic AL amyloidosis and 18 patients with wild type transthyretin (ATTRwt) amyloidosis with cardiomyopathy. Both non-invasive consensus criteria and serum amyloid P component (SAP) scintigraphy were used as substitute standards instead of liver biopsy for establishing liver involvement. RESULTS: Liver stiffness was higher in AL amyloidosis patients with liver involvement than in those without: this was observed using both consensus criteria (median 14.4 kPa vs. 8.1 kPa; p = 0.001) and SAP scintigraphy (median 20.9 kPa vs. 6.2 kPa; p < 0.001). Liver stiffness was also higher in AL amyloidosis patients with liver involvement compared to AL and ATTRwt amyloidosis patients with cardiac involvement. Based on receiver operating characteristic (ROC) curves a cut-off value of 14.4 kPa for stiffness was optimal to indicate liver involvement, providing sensitivity and specificity of 50% and 74%, respectively, using the consensus criteria and 63% and 90%, respectively, using SAP scintigraphy as standard. CONCLUSION: Liver stiffness is a promising tool to establish liver involvement in AL amyloidosis having potential to become part of updated criteria for liver involvement.

Specific metabolic impairments indicate loss of sustained liver improvements in metabolic dysfunction-associated steatotic liver disease treatment.

Background: High liver fat content (LFC) induces increased risks of both hepatic and extrahepatic progression in metabolic dysfunction-associated steatotic liver disease (MASLD), while maintaining a significant decline in magnetic resonance imaging-based proton density fat fraction (MRI-PDFF) (≥30% decline relative to baseline) without worsening fibrosis results in improved histological severity and prognosis. However, the factors associated with the loss of sustained responses to treatment remain unclear, and we aim to identify them. Methods: Consecutive treatment-naïve MASLD patients between January 2015 and February 2022, with follow-up until April 2023, were included in this prospective cohort study. LFC quantified by MRI-PDFF and liver stiffness measurements (LSM) determined by two-dimensional shear wave elastography (2D-SWE) were evaluated at weeks 0, 24 and 48. MRI-PDFF response was defined as a ≥30% relative decline in PDFF values, and LSM response was defined as a ≥1 stage decline from baseline. Results: A total of 602 MASLD patients were enrolled. Of the 303 patients with a 24-week MRI-PDFF response and complete follow-up of 48 weeks, the rate of loss of MRI-PDFF response was 29.4%, and multivariable logistic regression analyses showed that 24-week insulin resistance (IR), still regular exercise and caloric restriction after 24 weeks, and the relative decline in LFC were risk factors for loss of MRI-PDFF response. Loss of LSM response at 48 weeks occurred in 15.9% of patients, and multivariable analysis confirmed 24-week serum total bile acid (TBA) levels and the relative decline in TBA from baseline as independent predictors. No significant association was found at 48 weeks between loss of MRI-PDFF response and loss of LSM response. Conclusions: MASLD patients with IR and high TBA levels are at higher risks of subsequent diminished sustained improvements of steatosis and fibrosis, respectively.

Liver stiffness in hepatocellular carcinoma and chronic hepatitis patients: Hepatitis B virus infection and transaminases should be considered.

BACKGROUND: Liver condition is a crucial prognostic factor for patients with hepatocellular carcinoma (HCC), but a convenient and comprehensive method to assess liver condition is lacking. Liver stiffness (LS) measured by two-dimensional shear wave elastography may help in assessing liver fibrosis and liver condition. Chronic hepatitis B (CHB) is an important risk factor for HCC progression, but LS was found to be less reliable in assessing liver fibrosis following hepatitis viral eradication. We hypothesize that the status of hepatitis virus infection would affect the accuracy of LS in assessing the liver condition. AIM: To test the feasibility and impact factors of using LS to assess liver condition in patients with HCC and CHB. METHODS: A total of 284 patients were retrospectively recruited and classified into two groups on the basis of serum CHB virus hepatitis B virus (HBV)-DNA levels [HBV-DNA ≥ 100.00 IU/mL as Pos group (n = 200) and < 100.00 IU/mL as Neg group (n = 84)]. Correlation analyses and receiver operating characteristic analyses were conducted to evaluate the relationship between LS and liver condition. RESULTS: A significant correlation was found between LS and most of the parameters considered to have the ability to evaluate liver condition (P < 0.05). When alanine aminotransferase (ALT) concentrations were normal (≤ 40 U/L), LS was correlated with liver condition indices (P < 0.05), but the optimal cutoff of LS to identify a Child-Pugh score of 5 was higher in the Neg group (9.30 kPa) than the Pos group (7.40 kPa). When ALT levels were elevated (> 40 U/L), the correlations between LS and liver condition indices were not significant (P > 0.05). CONCLUSION: LS was significantly correlated with most liver condition indices in patients with CHB and HCC. However, these correlations varied according to differences in HBV-DNA and transaminase concentrations.

Circulating miR-122-5p, miR-151a-3p, miR-126-5p and miR-21-5p as potential predictive biomarkers for Metabolic Dysfunction-Associated Steatotic Liver Disease assessment.

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a worldwide leading cause of liver-related associated morbidities and mortality. Currently, there is a lack of reliable non-invasive biomarkers for an accurate of MASLD. Hence, this study aimed to evidence the functional role of miRNAs as potential biomarkers for MASLD assessment. Data from 55 participants with steatosis (MASLD group) and 45 without steatosis (control group) from the Fatty Liver in Obesity (FLiO) Study (NCT03183193) were analyzed. Anthropometrics and body composition, biochemical and inflammatory markers, lifestyle factors and liver status were evaluated. Circulating miRNA levels were measured by RT-PCR. Circulating levels of miR-122-5p, miR-151a-3p, miR-126-5p and miR-21-5p were significantly increased in the MASLD group. These miRNAs were significantly associated with steatosis, liver stiffness and hepatic fat content. Logistic regression analyses revealed that miR-151a-3p or miR-21-5p in combination with leptin showed a significant diagnostic accuracy for liver stiffness obtaining an area under the curve (AUC) of 0.76 as well as miR-151a-3p in combination with glucose for hepatic fat content an AUC of 0.81. The best predictor value for steatosis was obtained by combining miR-126-5p with leptin, presenting an AUC of 0.95. Circulating miRNAs could be used as a non-invasive biomarkers for evaluating steatosis, liver stiffness and hepatic fat content, which are crucial in determining MASLD.

Association between composite dietary antioxidant index and metabolic dysfunction associated steatotic liver disease: result from NHANES, 2017-2020.

Background: The development of metabolic dysfunction associated steatotic liver disease (MASLD) has been associated with lipid accumulation, oxidative stress, endoplasmic reticulum stress, and lipotoxicity. The Composite Dietary Antioxidant Index (CDAI) is a comprehensive score representing an individual intake of various dietary antioxidants, including vitamin A, vitamin C, vitamin E, selenium, zinc, and carotenoids. This study investigated the association between CDAI and MASLD. Materials and methods: Clinical and demographic data, as well as ultrasound transient elastography measurements at baseline, were collected from the National Health and Nutrition Examination Survey 2017-2020 (NHANES 2017-2020). The controlled attenuation parameter was utilized to diagnose the presence of hepatic steatosis and to categorize individuals into those with and without MASLD. Liver stiffness was measured by ultrasound transient elastography, and subjects were classified as those with and without advanced liver fibrosis. Results: This study included 5,884 adults, of whom 3,433 were diagnosed with MASLD, resulting in a weighted prevalence of 57.3%. After adjusting for covariates, the odds ratios for MASLD were 0.96 (95% CI: 0.82, 1.12) in the second quartile, 0.80 (95% CI: 0.68, 0.95) in the third quartile and 0.60 (95% CI: 0.49, 0.73) in the fourth quartile, respectively. CDAI, however, was not significantly associated with advanced liver fibrosis. Conclusion: These findings suggested that scores on the CDAI were linearly and negatively associated with the prevalence of MASLD in the United States adults.

Silymarin decreases liver stiffness associated with gut microbiota in patients with metabolic dysfunction-associated steatotic liver disease: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Despite centuries of traditional use of silymarin for hepatoprotection, current randomized controlled trial (RCT) studies on the effectiveness of silymarin in managing metabolic dysfunction-associated steatotic liver disease (MASLD) are limited and inconclusive, particularly when it is administered alone. The low bioavailability of silymarin highlights the possible influence of gut microbiota on the effectiveness of silymarin; however, no human studies have investigated this aspect. OBJECTIVE: To determine the potential efficacy of silymarin in improving MASLD indicators and to investigate the underlying mechanisms related to gut microbiota. METHOD: In this 24-week randomized, double-blind, placebo-controlled trial, 83 patients with MASLD were randomized to either placebo (n = 41) or silymarin (103.2 mg/d, n = 42). At 0, 12, and 24 weeks, liver stiffness and hepatic steatosis were assessed using FibroScan, and blood samples were gathered for biochemical detection, while faecal samples were collected at 0 and 24 weeks for 16S rRNA sequencing. RESULTS: Silymarin supplementation significantly reduced liver stiffness (LSM, -0.21 ± 0.17 vs. 0.41 ± 0.17, P = 0.015) and serum levels of γ-glutamyl transpeptidase (GGT, -8.21 ± 3.01 vs. 1.23 ± 3.16, P = 0.042) and ApoB (-0.02 ± 0.03 vs. 0.07 ± 0.03, P = 0.023) but had no significant effect on the controlled attenuation parameter (CAP), other biochemical indicators (aminotransferases, total bilirubin, glucose and lipid parameters, hsCRP, SOD, and UA), physical measurements (DBP, SBP, BMI, WHR, BF%, and BMR), or APRI and FIB-4 indices. Gut microbiota analysis revealed increased species diversity and enrichment of Oscillospiraceae in the silymarin group. CONCLUSION: These findings suggest that silymarin supplementation could improve liver stiffness in MASLD patients, possibly by modulating the gut microbiota. TRIAL REGISTRATION: The trial was registered at the Chinese Clinical Trial Registry (ChiCTR2200059043).

A 6-month randomized controlled trial for vitamin E supplementation in pediatric patients with Gaucher disease: Effect on oxidative stress, disease severity and hepatic complications.

Enzymatic deficiency in Gaucher disease (GD) may induce oxidative stress. Vitamin E is the nature's most effective lipid-soluble antioxidant. This prospective clinical trial assessed the oxidant-antioxidant status in Egyptian patients with GD and the efficacy and safety and of vitamin E as an adjuvant antioxidant therapy. Forty children and adolescents with GD on stable doses of enzyme replacement therapy (ERT) were enrolled. Abdominal ultrasonography and transient elastography were performed. Malondialdehyde (MDA), vitamin E, and antioxidant enzymes (reduced glutathione [GSH], superoxide dismutase [SOD], glutathione peroxidase [GPx], and peroxiredoxin 2 [PRDX2]) were assessed. Patients were compared with 40 age- and sex-matched healthy controls. Patients with GD were randomized either to receive oral vitamin E for 6 months or not. All patients with GD had significantly higher MDA levels with lower levels of vitamin E and antioxidant enzymes compared with healthy controls (p < 0.001). Vitamin E and PRDX2 were negatively correlated to severity score index (SSI), lyso GL1, and MDA. After 6 months of vitamin E supplementation, SSI and liver and spleen volumes and liver stiffness were significantly lower. Lyso GL1 and MDA were significantly decreased post-vitamin E therapy while antioxidant enzymes were significantly higher compared with baseline levels and with patients without vitamin E therapy. Oxidative stress is related to disease severity in pediatric patients with GD. A 6-month vitamin E supplementation for those patients represents a safe therapeutic adjuvant agent increasing the efficacy of ERT, reducing oxidative stress, and improving outcomes.

Fully automated hybrid approach on conventional MRI for triaging clinically significant liver fibrosis: A multi-center cohort study.

Establishing reliable noninvasive tools to precisely diagnose clinically significant liver fibrosis (SF, ≥F2) remains an unmet need. We aimed to build a combined radiomics-clinic (CoRC) model for triaging SF and explore the additive value of the CoRC model to transient elastography-based liver stiffness measurement (FibroScan, TE-LSM). This retrospective study recruited 595 patients with biopsy-proven liver fibrosis at two centers between January 2015 and December 2021. At Center 1, the patients before December 2018 were randomly split into training (276) and internal test (118) sets, the remaining were time-independent as a temporal test set (96). Another data set (105) from Center 2 was collected for external testing. Radiomics scores were built with selected features from Deep learning-based (ResUNet) automated whole liver segmentations on MRI (T2FS and delayed enhanced-T1WI). The CoRC model incorporated radiomics scores and relevant clinical variables with logistic regression, comparing routine approaches. Diagnostic performance was evaluated by the area under the receiver operating characteristic curve (AUC). The additive value of the CoRC model to TE-LSM was investigated, considering necroinflammation. The CoRC model achieved AUCs of 0.79 (0.70, 0.86), 0.82 (0.73, 0.89), and 0.81 (0.72-0.91), outperformed FIB-4, APRI (all p < 0.05) in the internal, temporal, and external test sets and maintained the discriminatory power in G0-1 subgroups (AUCs range, 0.85-0.86; all p < 0.05). The AUCs of joint CoRC-LSM model were 0.86 (0.79-0.94), and 0.81 (0.72-0.90) in the internal and temporal sets (p = 0.01). The CoRC model was useful for triaging SF, and may add value to TE-LSM.

Prevalence, clinical significance and prognosis value of liver stiffness measurement anomalies in transthyretin cardiac amyloidosis.

Background - Laboratory liver anomalies are common in cardiac amyloidosis; however, their significance regarding liver stiffness is unknown. The aim of this study was to investigate the prevalence, clinical significance, and prognostic value of liver stiffness measurement (LSM) anomalies in transthyretin cardiac amyloidosis (ATTR-CA). Methods - Consecutive patients diagnosed with ATTR-CA who underwent liver stiffness assessment were included in the study. Demographic, clinical, laboratory, transthoracic echocardiography and liver stiffness data were retrospectively collected. LSM was obtained through either transient elastography or supersonic shear imaging. Patient cohort was divided in two groups according to a 10 kPa threshold. Follow up data were collected for the occurrence of hospitalization for heart failure and all-cause death. Results - Two hundred and eighty-four patients with ATTR-CA - 26 (9 %) hereditary variant ATTR, 258 (91 %) wild-type ATTR - were included. A LSM over 10 kPa was found in 4 (15 %) and 98 (38 %) patients with ATTRv and ATTRwt respectively (p = 0.02). Among patients with ATTRwt, high LSM was more frequent in advanced stages of ATTR-CA and was associated with increased risk of hospitalization for heart failure after multivariate analysis with a hazard ratio of 2.41 [1.05-5.55] (p = 0.04). Among patients with NYHA stage 1, 28 % presented high LSM associated with high NT-proBNP levels. Integration of high LSM with NT-proBNP and estimated glomerular filtration rate provided a better estimate of patient survival. Conclusion - LSM over 10 kPa is found in up to 36 % of patients with ATTR-CA and is associated with advanced stages of cardiomyopathy and increased risk of hospitalization for heart failure in ATTRwt patients.

Liver stiffness as a prognostic parameter and tool for risk stratification in advanced cardiac transthyretin amyloidosis.

BACKGROUND: In light of increasing therapeutic options, risk stratification of advanced cardiac transthyretin amyloidosis (ATTR-CA) is gaining clinical importance to avoid ineffective treatments. Liver stiffness as a marker of hypervolemia and hepatic congestion might predict mortality in advanced ATTR-CA and allow to identify patients at highest risk. METHODS: Proven ATTR-CA patients underwent repeated vibration-controlled transient elastography (VTCE) and standardized serial workup within the local amyloidosis cohort study AmyKoS. Spearman correlation analyses and Cox regressions were performed to evaluate the prognostic value. RESULTS: 41 patients with ATTR-CA were included with median age of 76.6 (55.1-89.1) years, of which 90.2% were male and > 92% wild-type ATTR-CA. In total, 85 VCTE examinations were performed. Median follow-up was 43.7 (2.4-75.6) months; 26.8% of the patients died. At the first clinical evaluation, median left ventricular (LV) absolute global longitudinal strain (GLS) was 11.4 (5.2-19.0) % and median liver stiffness was 6.3 (2.4-22.9) kPa, both significantly correlated with mortality. NT-proBNP possessed statistically significant predictive power in ATTR-CA with more preserved LV function (absolute GLS ≥ 10), whereas stiffness seemed to be more discriminative for ATTR-CA with absolute GLS < 10. The use of alternative congestion surrogates such as liver vein dilation and tricuspid regurgitation peak velocity (tr-vmax) showed congruent results. CONCLUSION: Liver stiffness shows prognostic value regarding all-cause mortality and allows risk stratification in advanced ATTR-CA, particularly in those with markedly impaired longitudinal LV function. These results are transferable to other congestion surrogates.

A Real-World Experience Utilizing the FAST Score to Identify Patients With Nonalcoholic Steatohepatitis Fibrosis.

Background and Aims: We aimed to test the performance of the Fibroscan-aspartate aminotransferase (FAST) score, a noninvasive test, to identify nonalcoholic steatohepatitis (NASH) and significant fibrosis (NASH + ≥F2) in a cohort of patients with a histological diagnosis of NASH, using a cutoff of ≥0.35 as a rule in factor. We also compared performance to liver stiffness measurement (LSM) ≥8 kPa and the fibrosis-4 index (FIB-4) ≥1.3 and attempted to identify risk factors to develop a model for improving diagnostic accuracy. Methods: Patients with histologically confirmed NASH were identified from 2020-2021. Demographic information, laboratory data, and LSM were collected. The FAST score and FIB-4 were calculated. Univariate and backward entry multivariate logistic regression analyses were performed to identify risk factors in addition to the FAST score ≥0.35 that are associated with an accurate histological diagnosis of NASH + ≥F2. Discrimination and overall accuracy were assessed using area under receiver operating characteristic curves. Results: Using a rule in cutoff of ≥0.35, the FAST score performed with a sensitivity, specificity, negative predictive value, and positive predictive value of 96.4%, 36.8%, 77.7%, and 81.8%, respectively. Age (P = .05) and FAST ≥0.35 (P = .001) correctly identified histologically confirmed NASH + ≥F2. The FAST + age model outperformed FAST ≥0.35 (0.70, confidence interval [CI]: 0.55-0.84), LSM ≥8 kPa (0.72, CI: 0.59-0.85), and FIB-4 ≥1.3 (0.73, CI: 0.59-0.87) with a c-statistic of 0.78 (CI: 0.64-0.92). Conclusion: A FAST score with a rule cutoff of ≥0.35 performed well (c-statistic: 0.70) and was superior to LSM and FIB-4 when age was incorporated into the model (0.78) in detecting NASH + ≥F2 fibrosis in the real world.

Serum immunoglobulin A levels: Diagnostic utility in alcoholic liver disease and association with liver fibrosis in steatotic liver disease.

The relationship between immunoglobulin A (IgA) levels and chronic liver disease remains poorly understood. The present study evaluated the clinical significance of IgA in 478 new patients who visited the Outpatient Clinic of Nagasaki Harbor Medical Center (Nagasaki, Japan). Serum IgA levels in comparison to liver stiffness (LS), as measured using a FibroScan® device, were evaluated in 358 patients. Furthermore, in 270 patients, the associations between serum IgA levels and body composition were analyzed using computed tomography. The IgA levels of patients in the groups with Child-Pugh classification B and C (CPGBC), alcoholic liver disease (ALD), steatotic liver disease (SLD) or diabetes were higher than the IgA levels of patients in the groups with CPGA, non-ALD, non-SLD or no diabetes, respectively. Logistic regression analysis showed that CPGBC, ALD, high IgG (>1,700 mg/dl), high macrophage galactose-specific lectin-2 binding protein glycosylation isomer (M2BPGi) (>1 cut-off index) and diabetes were contributing factors for high serum IgA level (>410 mg/dl). The ratio of IgA level divided by IgG level was highest in patients with ALD, followed by those with metabolic dysfunction-associated SLD (MASLD) and non-SLD. In SLD, IgA level was associated more with LS than M2BPGi and fibrosis-4 (FIB-4) in multiple regression analysis. In the receiver operating characteristic analysis, IgA level, M2BPG, and FIB-4 had similar area under the curve values for discriminating high LS (>8 kPa) from low LS (≤8 kPa) in SLD. IgA levels were also associated with visceral fat, and this association was only found in women. In conclusion, elevated IgA is an indicator of liver fibrosis that also reflects the presence of diabetes and an increased visceral fat level. Therefore, IgA is considered a useful marker of liver disease severity in the current era of increased SLD.
