Abstract
BACKGROUND Early stages of hepatitis B virus (HBV) infection usually involve inflammation of the liver. Patients with chronic infection have an increased risk of progressive liver fibrosis, cirrhosis, and life-threatening clinical complications of end-stage hepatocellular carcinoma (HCC). CONTENT Early diagnosis of hepatic fibrosis and timely clinical management are critical to controlling disease progression and decreasing the burden of end-stage liver cancer. Fibrosis staging, through its current gold standard, liver biopsy, improves patient outcomes, but the clinical procedure is invasive with unpleasant post-procedural complications. Routine blood test markers offer promising diagnostic potential for early detection of liver disease without biopsy. There is a plethora of candidate routine blood test markers that have gone through phases of biomarker validation and have shown great promise, but their current limitations include a predictive ability that is limited to only a few stages of fibrosis. However, the advent of machine learning, notably pattern recognition, presents an opportunity to refine blood-based non-invasive models of hepatic fibrosis in the future. SUMMARY In this review, we highlight the current landscape of routine blood-based non-invasive models of hepatic fibrosis, and appraise the potential application of machine learning (pattern recognition) algorithms to refining these models and optimising clinical predictions of HBV-associated liver disease. OUTLOOK Machine learning via pattern recognition algorithms takes data analytics to a new realm, and offers the opportunity for enhanced multi-marker fibrosis stage prediction using pathology profile that leverages information across patient routine blood tests.

Elevated AST/ALT ratio is associated with all-cause mortality in patients with stable coronary artery disease: a secondary analysis based on a retrospective cohort study. Sci Rep 2022; 12:9231. [PMID: 35654995 PMCID: PMC9163143 DOI: 10.1038/s41598-022-13355-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 05/24/2022] [Indexed: 11/23/2022] Open
Abstract
The aim of this study is to explore the association between the aspartate amino transferase (AST)/alanine aminotransferase (ALT) ratio and all-cause mortality (ACM) in stable coronary artery disease (CAD) patients treated by percutaneous coronary intervention (PCI). The study is a secondary analysis of a retrospective cohort study involving 203 stable CAD patients. Patients were divided into two groups, based on the optimal AST/ALT ratio threshold calculated by the ROC curve (low group: AST/ALT ratio < 1.40; high group: AST/ALT ratio ≥ 1.40). Results were compared using hazard ratio (HR) and a 95% confidence interval (CI). ACM occurred in 18 patients after an average follow-up time of 749 (435–1122) days. Among them, ACM occurred in 6 patients in the low group and 12 patients in the high group, with significant differences between the groups (4.65% versus 16.22%, P value = 0.005). In the Kaplan–Meier analysis, an elevated AST/ALT ratio was associated with increased ACM in stable ACD patients (HR 3.78, 95% CI 1.44–9.93, P value < 0.001). An elevated AST/ALT ratio was still found to be an independent prognostic factor for ACM (HR 2.93, 95% CI 1.08–7.91, P value = 0.034) after adjusting for potential confounders. Therefore, an elevated AST/ALT ratio is an independent prognostic factor for ACM in stable ACD patients.

Assessment of liver fibrosis by transient elastography and multi-parameters model in young children with chronic hepatitis B virus infection. BMC Infect Dis 2022; 22:160. [PMID: 35180839 PMCID: PMC8857795 DOI: 10.1186/s12879-022-07142-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 02/08/2022] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE This study aimed to compare the diagnostic value of the single or combined applications of transient elastography (TE) and multivariate indicators with biopsy for the detection of liver fibrosis in children caused by chronic hepatitis B (CHB). METHODS This study included 148 CHB children treated at Hunan Children's Hospital from January 1st 2015 to December 31st 2018, aged from 0.83 to 14.58 years old. All patients underwent liver biopsy (LB), of which 43 patients underwent TE. Multiple clinical data, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), Platelet (PLT), and HBV-deoxyribonucleic acid (HBV DNA) of all patients were collected. The diagnostic values for CHB of TE and its combinations with these indicators were measured. The patients were classified in two ways: no hepatic fibrosis group (F0) versus fibrosis group (F ≥ 1), and no significant hepatic fibrosis group (F < 2) versus significant hepatic fibrosis group (F ≥ 2). The statistical assessment was performed between groups within each classification to compare the diagnostic value of different parameters. RESULTS The operating characteristic area under curve (AUC) of liver fibrosis diagnosed by liver stiffness measurement (LSM) which obtained by TE, AST-to-PLT ratio index (APRI), and fibrosis-4 index (FIB-4) were 0.740, 0.701, and 0.651, while the corresponding cut-off values were 5.9 kPa, 0.50, and 0.10, respectively. The AUC of significant liver fibrosis diagnosed by LSM, APRI and FIB-4 were 0.849, 0.701, and 0.509, while the corresponding cut-off values were 8.4 kPa, 0.76, and 0.08, respectively. While with the combinations of LSM and APRI, LSM and FIB-4, LSM and APRI and FIB-4, APRI and FIB-4, the AUC of significant liver fibrosis were 0.866, 0.855, 0.869, and 0.684, respectively. The AUC of significant liver fibrosis diagnosed by the LSM was significantly higher than APRI and FIB-4. CONCLUSIONS The diagnostic value of transient elastography was better than that of APRI and FIB-4 for CHB children with significant liver fibrosis. In addition, TE also has relatively high application values on the diagnosis of patients with different degrees of liver fibrosis caused by CHB.

Abstract
BACKGROUND Two-dimensional shear wave elastography (2D-SWE), magnetic resonance elastography (MRE), aspartate transaminase-to-platelet ratio index (APRI), fibrosis index based on 4 factors (FIB-4), and King's score have been proposed for diagnosing fibrosis. METHODS Literature databases were searched until October 1st, 2020. The summary area under the receiver operating characteristic curve (AUROC), the summary diagnostic odds ratios, and the summary sensitivities and specificities were used to assess the performance of these noninvasive methods for staging fibrosis. RESULTS Our final data contained 72 studies. The prevalence of significant fibrosis, advanced fibrosis, and cirrhosis was 58.3%, 36.2%, and 20.5%, respectively, in chronic hepatitis B (CHB). For 2D-SWE and MRE, the summary AUROCs were 0.89 and 0.97, 0.95 and 0.97, and 0.94 and 0.97 for significant fibrosis, advanced fibrosis, and cirrhosis, respectively. The summary AUROCs using APRI and FIB-4 for detecting significant fibrosis, advanced fibrosis, and cirrhosis were 0.76 and 0.75, 0.74 and 0.77, and 0.77 and 0.82, respectively. The summary AUROCs of King's score for detecting significant fibrosis and cirrhosis were 0.77 and 0.83, respectively. CONCLUSION MRE and 2D-SWE may show the best diagnostic accuracy for predicting fibrosis in CHB. Among the three serum markers, King's score may be more useful for diagnosing fibrosis.

Abstract
OBJECTIVES Staging of fibrosis in chronic liver disease is important for prognosis and treatment planning. Liver biopsy is the gold standard in fibrosis assessment; however, new methods for fibrosis and stiffness measurement exist which have not been evaluated in patients with Wilson's disease. To evaluate the accuracy of collagen proportionate area (CPA), transient elastography and shear wave elastography (SWE) in the assessment of liver fibrosis in adult patients with Wilson's disease. METHODS In this retrospective study of 60 patients with Wilson's disease, results of percutaneous cutting liver biopsy assessed using the Ishak fibrosis score and CPA were compared with liver stiffness measured with transient elastography and SWE. RESULTS CPA correlated with the Ishak score (r = 0.45; P = 0.001) and transient elastography results correlated with SWE measurements (r = 0.80; P = 0.0001). In contrast, transient elastography or SWE did not significantly correlate with the Ishak score or CPA. CONCLUSION Collagen content assessment may be useful for estimation of liver fibrosis in patients with Wilson's disease. However, single time-point elastographic liver stiffness measurements have a limited diagnostic value in Wilson's disease.

Abstract
Background Chronic active hepatitis C virus (HCV) infection is a major public health problem and causes liver fibrosis (LF) up to liver cirrhosis (LC). LF can be estimated by non-invasive, easy handling methods. With implementation of new HCV therapies, elimination rates of HCV are near 100%, resulting in less clinical complications and costs. The aim of our study was to evaluate the positive influence of HCV treatment on liver stiffness by non-invasive assessments of LF. Methods Sixty-two patients with HCV were treated with antiviral drug regimes. Serological fibrosis scores and ultrasound elastography (acoustic radiation force impulse and shear wave elasticity imaging (ARFI-SWEI)) were used for LF assessment on day 0 and 6 months after therapy. Results Antiviral treatment was successful in all cases. ARFI-SWEI measurements showed an improvement of all LF stages. Results of serological markers and scores were heterogeneous. Significant positive effects of treatment were seen for aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) scores, only. Further Pearson's coefficient showed moderate till very high correlations for ARFI-SWEI and FIB-4/APRI scores. Conclusion Today HCV therapy is able to cure HCV. Positive influences are improvement of LF stages. ARFI-SWEI, APRI and FIB-4 score are useful, easy handling tools to verify positive influence of HCV treatment on LF alone or in combination.

Abstract
INTRODUCTION Several barriers remain in the hepatitis C care cascade, which need to be removed in order to eliminate Chronic Hepatitis C. These barriers include deficiencies in screening and confirmatory diagnosis as well as difficulties in accessing treatment. AIMS To identify factors associated with the non-referral of patients with positive HCV-antibody and to identify factors associated with loss of follow-up or non-attendance of these patients to specialist consultation after their referral. METHODS Observational and retrospective single-centre-study, including all positive HCV serologies performed between January 2013 and May 2018 in the Virgen Macarena health area before implementing the one-step diagnosis. Non-referred patients and patients who were lost to follow-up after being referred were identified. RESULTS A total of 54 (77.4%) patients diagnosed in PC and 54 (22.2%) from hospital specialists were not referred (p <0.001). Predictors for non-referral were: stay in prison/ institutionalized (p = 0.04), suffering COPD (p = 0.07), a normal AST value (p = 0.034) or test requested by PCP (p = 0.004). Patients referred from PC were more likely to be lost to follow-up than those referred from hospital specialists (p <0.001). Predictors for loss of follow-up included: opioid replacement therapy (p = 0.034), absence of high blood pressure (p = 0.039) and test requested by PCP (p = 0.049). CONCLUSIONS A high percentage of patients with positive HCV serology were not referred or lost follow-up, mainly those belonging to high risk social groups or those with associated comorbidities. Patients with average values of transaminases or those diagnosed in primary care were also less referred.

Abstract
Background The forkhead box protein 3 (FOXP3) transcription factor is one of the main markers of immunological suppression in different pathological profiles, and the presence of polymorphic variants may alter the gene expression of this factor. Despite descriptions of an association between the presence of the rs2232365 polymorphism and chronic diseases, the role of the sex variant in this context has not yet been elucidated, as the FOXP3 gene is located on the human sex chromosome X. Results To contribute to this topic, 323 women and 373 men were enrolled in the study, of which 101 were diagnosed with chronic viral liver diseases (39 women and 62 men), 67 with HTLV-1 infection (44 women and 23 men), 230 with coronary artery disease (91 women and 139 men) and 298 healthy and uninfected blood donors (149 women and men). They were genotyped for the rs2232365 polymorphism. The rs2232365 polymorphism was associated with clinical and pathological aspects and biomarkers of viral infections only in men, with functional differences between different infections. Conclusions A relationship is suggested between sex and FOXP3 rs2232365 polymorphism, resulting in different biological repercussions.

Abstract
OBJECTIVES This study was to evaluate the diagnostic value of liver extracellular volume (LECV) for the staging of liver fibrosis in a cynomolgus monkey model of nonalcoholic steatohepatitis (NASH). METHODS Forty-eight cynomolgus monkeys were enrolled in this prospective study. There are 17 healthy monkeys and 31 monkeys with NASH. Ten of these monkeys were used for repeatability assessment. The remaining 38 monkeys were used to compare LECV with other indicators including pathology fibrosis score, native T1, and serum chemical indexes by Spearman, Pearson correlation test, and ROC curves. The inter-reader variability was assessed by interclass correlation. The repeatability measurement of LECV was analyzed using Bland-Altman plots and the coefficient of variation. Partial correlation analysis was performed to assess the effects of fat content and inflammation scores on the correlation between LECV/T1 and liver fibrosis score. RESULTS This study demonstrated a good intra-reader agreement (intraclass correlation = 0.79) of LECV in all monkeys and an excellent repeatability in 10 monkeys (coefficient of variation = 2.01%). The LECV has a strong correlation with the fibrosis score (r = 0.949; p < 0.0001), low-density lipoprotein (r = 0.72; p < 0.0001), and cholesterol (r = 0.70; p < 0.0001). LECV showed high diagnostic efficacy in the diagnosis of liver fibrosis (area under the curve of ROC, 0.945~1; p < 0.001). CONCLUSIONS LECV may serve as a noninvasive valuable biomarker for the quantification and differentiating of the non-severe liver fibrosis (stage ≤ F3). However, circulating serum markers low-density lipoprotein and cholesterol (CHO) may not serve for this purpose. KEY POINTS • This paper demonstrated the excellent repeatability (intraclass correlation coefficient = 0.79) of LECV in monkey animal model. • LECV-MRI has a strong correlation with histopathological fibrosis score stage (r = 0.949; p < 0.0001) and shows high diagnostic efficacy in the staging of non-severe liver fibrosis (the area under ROC curve ≥ 0.945). • The new fibrosis score maps appeared to provide a better imaging tool for the spatial assessment of liver fibrosis. It may eventually facilitate the diagnosis of liver fibrosis distribution.

Association between Alanine Aminotransferase/Aspartate Aminotransferase Ratio (AST/ALT Ratio) and Coronary Artery Injury in Children with Kawasaki Disease. Cardiol Res Pract 2020; 2020:8743548. [PMID: 32274211 PMCID: PMC7125506 DOI: 10.1155/2020/8743548] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Revised: 01/06/2020] [Accepted: 01/25/2020] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVE To investigate the association between the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AST/ALT ratio, AAR) and intravenous immunoglobulin (IVIG) resistance, coronary artery lesions (CAL), and coronary artery aneurysms (CAA) in children with Kawasaki disease (KD). DESIGN We retrospectively studied 2678 children with KD and divided them into two groups: a low-AAR group and a high-AAR group with a median AAR of 1.13 as the cut-off point. The differences in laboratory data, clinical manifestations, and coronary artery damage rates were compared between the two groups. RESULTS The incidence of CAL was higher in the low-AAR group than in the high-AAR group at 2 and 3-4 weeks after illness onset (p < 0.001, respectively). The IVIG resistance rate was significantly higher in the low-AAR group than in the high-AAR group (29.94% vs 21.71%, p < 0.001). The levels of C-reactive protein, erythrocyte sedimentation rate, white blood cell count, bilirubin, fibrinogen, thrombin time, D-dimer, and brain natriuretic peptide were also significantly higher in the low-AAR group compared with the high-AAR group. The levels of albumin and IgG were significantly lower in the low-AAR group compared with those of the high-AAR group. The proportion of typical KD cases in the low-AAR group was significantly higher than that in the high-AAR group. Low-AAR correlated with the risk of coronary artery damage and IVIG resistance. CONCLUSION Children with KD who had low-AAR value were more likely to develop coronary artery damage and IVIG resistance. Low AAR is a risk factor for CAL, CAA, and IVIG resistance in KD.

Abstract
OBJECTIVES The liver biopsy is the gold standard for determining the level of fibrosis in chronic hepatitis B infection (CHBI). Nonetheless, it is possible to predict liver fibrosis through some noninvasive methods such as noninvasive scoring (NIS) of some serum biomarkers obtained from routine blood tests. We aimed to evaluate the diagnostic accuracy of nine NIS for detecting advanced fibrosis in CHBI. PATIENTS AND METHODS We reviewed the hospital records of CHBI cases with liver biopsy between January 2011 and December 2016 retrospectively. Using Ishak scoring method, we classified fibrosis stage 1-2 as mild and 3-6 as advanced fibrosis. We calculated the NIS by considering the age, platelet count, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, platelet, and international normalized ratio values at the time of the biopsy. RESULTS The mean age of 202 patients was 37.69± 11.33 years. In cases with advanced fibrosis, the age, gammaglutamyltransferase, and international normalized ratio values were higher and platelet count was lower (P < 0.05). Mean platelet volume was not different between the two groups (P = 0.499). The median values of γ-glutamyl peptidase-platelet ratio (GPR), FibroQ, Goteborg University Cirrhosis Index, fibrosis-4 (FIB-4), aspartate aminotransferase-platelet ratio index, age-platelet index, and King scoring were significantly higher in the advanced fibrosis group. The highest area under the curve value was in GPR [AUC = 0.731 (0.639-0.788); P = 0.000] in the receiver operating characteristic curve analysis. Cirrhosis Discriminant Score and Aspartate aminotransferase-to-alanine aminotransferase ratio tests were not valuable in detecting advanced fibrosis. FIB-4 had the highest (0.678) diagnostic accuracy rate. CONCLUSION We found that the calculation of NIS before liver biopsy, especially GPR and FIB-4, may be useful for predicting advanced fibrosis in cases with CHBI.

Abstract
BACKGROUND Liver biopsy is the criterion standard for diagnosing liver fibrosis, but it is not widely used to monitor liver fibrosis because of the invasiveness, risk of complications, and sample errors. Therefore, it is necessary to involve other techniques to monitor liver fibrosis or cirrhosis during clinical practice. The objective was to explore noninvasive indicators to predict advanced liver fibrosis in autoimmune hepatitis (AIH) patients. METHODS A total of 45 AIH patients and 47 healthy controls were recruited to this retrospective study. Complete blood count and liver function tests were performed for all subjects. AIH patients were divided into "no/minimal fibrosis" group and "advanced fibrosis" group based on liver biopsy. RESULTS AIH patients demonstrated significantly higher monocytes, MCV, RDW-CV, RDW-SD, NLR, RDW-CV/PLT, RDW-SD/PLT, TBIL, DBIL, GLB, ALT, AST, GGT, ALP, and GPR and lower WBC, neutrophils, lymphocytes, RBC, HGB, HCT, LMR, TP, ALB, and AAR compared with healthy controls. Patients with advanced fibrosis showed remarkably higher RDW-CV, RDW-SD, RDW-CV/PLT, RDW-SD/PLT, AAR, and FIB-4 and lower RBC, PLT, PCT, and ALB compared with the no/minimal fibrosis group. Logistic regression analysis showed that RDW-SD/PLT was an independent risk factor for advanced fibrosis with an OR (95% CI) of 2.647 (1.383-5.170). Receiver operating characteristic (ROC) analysis revealed that RDW-SD, RDW-CV/PLT, RDW-SD/PLT, FIB-4, and AAR had an area under the ROC curve (AUC) above 0.700 and RDW-SD/PLT had the largest AUC of 0.785 with a cutoff value of 0.239. CONCLUSION RDW-SD, RDW-CV/PLT, RDW-SD/PLT, FIB-4, and AAR were excellent noninvasive biomarkers and RDW-SD/PLT was an independent risk factor for predicting advanced fibrosis in AIH patients.

Abstract
The process of diagnosis and linkage to care in cases of hepatitis C virus (HCV) infection remains an obstacle to disease control. The aims of this study were to evaluate predictive factors for not undergoing RNA testing among patients with positive HCV serology and impact of incorporating an automated electronic alert with recommendations in clinical practice. We collected HCV antibody tests requested from October 2011 to September 2014 to evaluate the rate of RNA testing and predictive factors for not undergoing RNA testing. Since October 2014, an automated alert notification has been implemented to remind physicians for testing RNA after a positive HCV test and referral to specialist care. 41 403 HCV antibody tests were requested from 34 073 patients. 870 (2.55%) patients tested positive. After a median of follow-up of 57.0 months (range 45.6-82.1), 37.6% did not have RNA testing. The independent predictors for not undergoing RNA testing were primary care serology requests (P < 0.001), no history of drug use (P = 0.005) and a lack of social support (P = 0.015). The intervention impact was evaluated in a pre-alert cohort (October 2011-September 2014) and a post-alert cohort (October 2014-September 2015). After the incorporation of the alert, the rate of RNA testing increased from 62.4% to 77.7% (P < 0.001). Incomplete assessment of HCV infection is a challenge in primary care. The implementation of an automated alert for recommending RNA testing after a positive HCV antibody test is feasible in clinical practice and increases the rate of patients with RNA testing.

Performance of common imaging techniques vs serum biomarkers in assessing fibrosis in patients with chronic hepatitis B: A systematic review and meta-analysis. World J Clin Cases 2019; 7:2022-2037. [PMID: 31423434 PMCID: PMC6695542 DOI: 10.12998/wjcc.v7.i15.2022] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2019] [Revised: 06/25/2019] [Accepted: 07/03/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Noninvasive biomarkers have been developed to predict hepatitis B virus (HBV) related fibrosis owing to the significant limitations of liver biopsy. Both serum biomarkers and imaging techniques have shown promising results and may improve the evaluation of liver fibrosis. However, most of the previous studies focused on the diagnostic effects of various imaging techniques on fibrosis in all chronic liver diseases.
AIM To compare the performance of common imaging methods and serum biomarkers for prediction of significant fibrosis caused only by HBV infection.
METHODS A systematic review was conducted on the records available in PubMed, EMBASE, and the Cochrane Library electronic databases until December 2018. We systematically assessed the effectiveness of two serum biomarkers and three imagine techniques in predicting significant fibrosis solely caused by HBV infection. The serum biomarkers included aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis index based on the 4 factors (FIB-4). The three imaging techniques included acoustic radiation force impulse (ARFI), FibroScan, and magnetic resonance elastography (MRE). Three parameters, the area under the summary receiver operating characteristic curve (AUSROC), the summary diagnostic odds ratio, and the summary sensitivity and specificity, were used to examine the accuracy of all tests for liver fibrosis.
RESULTS Out of 2831 articles evaluated for eligibility, 204 satisfied the predetermined inclusion criteria for this current meta-analysis. Eventually, our final data contained 81 studies. The AUSROCs of serum biomarkers of APRI and FIB-4 were both 0.75. For imaging techniques (ARFI, FibroScan, and MRE), the areas were 0.89, 0.83, and 0.97, respectively. The heterogeneities of ARFI and FibroScan were statistically significant (I2 > 50%). The publication bias was not observed in any of the serum biomarkers or imaging methods.
CONCLUSION These five methods have attained an acceptable level of diagnostic accuracy. Imaging techniques, MRE in particular, demonstrate significant advantages in accurately predicting HBV-related significant fibrosis, while serum biomarkers are admissible methods.

Hepatoprotective Effects of Morchella esculenta against Alcohol-Induced Acute Liver Injury in the C57BL/6 Mouse Related to Nrf-2 and NF- κB Signaling. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:6029876. [PMID: 31396303 PMCID: PMC6664553 DOI: 10.1155/2019/6029876] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Revised: 05/18/2019] [Accepted: 06/11/2019] [Indexed: 12/14/2022]
Abstract
This study investigated the hepatoprotective effects of Morchella esculenta fruit body (ME) and the underlying mechanisms in mice with alcohol-induced acute liver injury. Systematic analysis revealed that ME contained 21 types of fatty acid, 17 types of amino acid, and 12 types of mineral. Subsequently, a mouse model of acute alcohol-induced liver injury was established by oral administration of alcohol for 14 days. Fourteen-day administration of ME prevented alcohol-induced increases in alanine aminotransferase and aspartate aminotransferase levels and reduced the activity of acetaldehyde dehydrogenase in blood serum and liver tissue. ME appears to regulate lipid metabolism by suppressing triglycerides, total cholesterol, and high-density lipoprotein in the liver. ME inhibited the production of inflammatory factors including chitinase-3-like protein 1 (YKL 40), interleukin-7 (IL-7), plasminogen activator inhibitor type 1 (PAI-1), and retinol-binding protein 4 (RBP4) in blood serum and/or liver tissue. ME treatment relieved the alcohol-induced imbalance in prooxidative and antioxidative signaling via nuclear factor-erythroid 2-related factor 2 (Nrf-2), as indicated by upregulation of superoxide dismutase-1, superoxide dismutase-2, catalase, heme oxygenase-1, and heme oxygenase-2 expression and downregulation of kelch-like ECH-associated protein 1 (Keap-1) in the liver. Moreover, ME reduced the levels of phosphorylated nuclear factor kappa-B kinase α/β, inhibitor of nuclear factor kappa-B α and nuclear factor kappa-B p65 (NF-κB p65) in the liver. The hepatoprotective effects of ME against alcohol-induced acute liver injury were thus confirmed. The mechanism of action may be related to modulation of antioxidative and anti-inflammatory signaling pathways, partially via regulation of Nrf-2 and NF-κB signaling.

Abstract
No consensus exists with respect to positive hepatitis B virus (HBV) DNA results and persistent normal or mildly elevated alanine aminotransferase (ALT). The aim of this study is to investigate the appropriate management and prognosis of these populations with chronic hepatitis B (CHB). A total of 235 subjects with positive HBV DNA results and persistent normal or mildly elevated ALT were enrolled in this study. Liver biopsy and liver stiffness measurements (LSM) were performed in all participants at baseline. Antiviral therapy was initiated in patients with significant hepatic inflammation (G ≥ 2) and/or fibrosis (S ≥ 2). The patients were divided into entecavir and adefovir groups based on HBV DNA load (>2000 IU/mL vs <2000 IU/mL). The liver biopsies were repeated at 72 weeks for the patients received antiviral therapy. We found that 112 subjects were hepatitis B e antigen (HBeAg) positive, and 123 subjects were negative. The corresponding median ALTs were 46 (39.5-52.5) and 48 (41.5-57.0) U/mL, respectively. G ≥ 2 and/or S ≥ 2 diseases were present in 48.8% (82/168) of the HBeAg-positive and 51.2% (86/168) of HBeAg-negative patients, respectively. In addition, 96 HBeAg-positive and 72 HBeAg-negative patients were divided into entecavir and adefovir groups. Meanwhile, liver biopsies had greater diagnostic accuracy for determining cirrhosis than LSM (0.711 vs 1.0, P < 0.0001). At the end of the study period, undetectable HBV DNA levels and normal ALT levels were observed in CHB-infected patients. Furthermore, the patients showed histologic improvement at 72 weeks compared with baseline measurements (G, 1.72 ± 1.00 vs 0.73 ± 0.88, P = 0.0002; S, 1.484 ± 0.90 vs 0.99 ± 1.13, P < 0.0001). Collectively, liver biopsy enhanced diagnostic accuracy for CHB-infected individuals with persistent normal or mildly elevated aminotransferase levels. Moreover, antiviral therapy can improve or regress the hepatic fibrosis and cirrhosis.

Current noninvasive liver reserve models do not predict histological fibrosis severity in hepatocellular carcinoma. Sci Rep 2018; 8:15074.

Abstract
The Ishak scoring system has been used to stage liver fibrosis. Ten noninvasive liver reserve models were proposed to assess the severity of liver fibrosis, but their performance in hepatocellular carcinoma (HCC) is unknown. We aimed to evaluate the correlation between these models and severity of fibrosis in patients with HCC. A total 464 patients with HCC undergoing surgical resection were retrospectively analyzed. Multivariate logistic regression analysis was performed to determine independent factors associated with advanced fibrosis (Ishak score 4 or higher). There were no significant correlations between all noninvasive models and severity of fibrosis in HCC (p for trend all >0.1). In subgroup analysis, cirrhosis discriminant index (CDS) and Lok’s index in hepatitis B-, and fibrosis index based on 4 factors (FIB-4), CDS and Lok’s index in hepatitis C-associated HCC, best correlated with the severity of liver fibrosis. Low platelet count, prolonged prothrombin time, hepatitis C and multiple tumors were independently associated with advanced fibrosis. Among the 10 models, CDS was the best model to predict cirrhosis. Currently used noninvasive liver reserve models do not well correlate with severity of histological fibrosis in HCC. New noninvasive models are required to improve the predictive accuracy of liver fibrosis in HCC.

Abstract
BACKGROUND & AIMS To avoid liver biopsy, many noninvasive models comprised of serum markers for liver fibrosis assessment have been developed. Given that most of them were developed in hepatitis C cohorts and few of them have been validated in Chinese hepatitis B patients, we aim to conduct this validation and compare their diagnostic accuracies in such a population. METHODS A total of 937 HBV-infected patients who underwent liver biopsy were included in this single-centre retrospective study. The diagnostic accuracies of the 17 noninvasive models were assessed by areas under the receiver-operating characteristic curves (AUROCs), using histologically evaluated fibrotic stages of the biopsy specimens as standards. To compare efficiencies of the models, a grading system based on AUROC levels was developed. RESULTS For discriminating significant fibrosis in all patients, the best three noninvasive models were King's score (AUROC = 0.756), Virahep-C model (AUROC = 0.756) and GPR (AUROC = 0.744); and for diagnosing cirrhosis, Lok index (AUROC = 0.832), FI (AUROC = 0.820) and FIB-4 (AUROC = 0.818) got the first three places. AUROCs in HBeAg-positive group were generally higher than those in HBeAg-negative group. In addition, based on the grading system, Virahep-C and GPR outstood others in evaluating liver fibrosis in all patients. CONCLUSIONS In Chinese HBV-infected patients, Virahep-C models and GPR had high accuracies in diagnosing liver fibrosis and cirrhosis, while the most discussed models like APRI and FIB-4 did not outstand. Assessment should take into account the HBeAg sero-status, since these noninvasive models were more appropriate for HBeAg-positive patients than HBeAg-negative ones.

Abstract
BACKGROUND Parenteral nutrition-associated cholestasis (PNAC) is a major cause of morbidity and mortality in premature infants. Early predictors of PNAC would have clinical value. We sought to evaluate risk factors and liver function testing as predictors of PNAC in premature infants with intestinal perforation. METHODS Medical records of infants with a gestational age <34 weeks, birth weight <2000 g, and intestinal perforation due to either necrotizing enterocolitis or spontaneous intestinal perforation were reviewed. We analyzed clinical data and the maximum values of the aspartate aminotransferase (AST) to platelet ratio index (APRI), alanine aminotransferase (ALT), AST to ALT ratio, and total bilirubin (TB). RESULTS Sixty infants were identified, 17 infants with PNAC and 43 infants without PNAC. Sepsis, time to initiation of enteral feeds after perforation, and duration of PN were associated with PNAC. Within 2 weeks following intestinal perforation, APRI, ALT, and TB each differed significantly between infants who later developed PNAC and those that did not. The best APRI cut-point was 0.4775 within 2 weeks after perforation (area under the receiver operating characteristic curve, 0.90; positive predictive value, 85%; and negative predictive value, 87%); the cut-point for ALT was 13.5 (0.90, 85%, 84%), and the cut-point for TB was 3.55 (0.82, 69%, 83%), respectively, at 2 weeks after perforation. AST to ALT ratio did not differ between groups. CONCLUSIONS APRI and ALT had reasonable predictive value for PNAC in premature infants with intestinal perforation, with the APRI the best predictor within 2 weeks after perforation.

Abstract
BACKGROUND AND AIM The aim of the study was to analyze the diagnostic performance and clinical utility of simple noninvasive tests for the detection of advanced fibrosis in patients with chronic hepatitis B (CHB) infection seen at a tertiary referral center in Germany. PATIENTS AND METHODS We retrospectively analyzed 239 adult CHB patients with available liver biopsies. Patient demographics, hepatitis B markers, antiviral treatment, laboratory parameters, results from liver imaging, and histology were recorded. The sensitivity, specificity, and positive and negative predictive values were determined along with the area under receiver operating characteristic curves (AUROC) using published formulas and cut-off values for fibrosis index based on the four factors, aspartate aminotransferase-alanine aminotransferase ratio index (AAR), aspartate aminotransferase-to-platelet ratio index (APRI), and age-platelet index. RESULTS The median documented duration of CHB infection was 31 months (range: 6-340 months); 86% of the patients were Caucasian and 71% were men. The AUROCs for the detection of advanced fibrosis were 0.75 [95% confidence interval (CI): 0.67-0.82], 0.72 (95% CI: 0.64-0.80), 0.48 (95% CI: 0.39-0.56), and 0.73 (95% CI: 0.66-0.81) for fibrosis index the four factors, APRI, AAR, and age-platelet index, respectively. Patients with advanced fibrosis on biopsy were misclassified as having mild fibrosis in 35% (APRI) to 82% (AAR) of cases. CONCLUSION Because of their moderate test performance (AUROCs: 0.48-0.75) and their high misclassification rate, we could not confirm a reliable clinical utility for the analyzed noninvasive fibrosis scoring systems for the prediction of advanced fibrosis in mostly Caucasian CHB patients.

Abstract
The gamma-glutamyl transpeptidase to platelet ratio (GPR) is a novel index to estimate liver fibrosis in chronic hepatitis B (CHB). Few studies compared diagnostic accuracy of GPR with other non-invasive fibrosis tests based on blood parameters. We analyzed diagnostic values of GPR for detecting liver fibrosis and compared diagnostic performances of GPR with APRI (aspartate aminotransferase-to-platelet ratio index), FIB-4 (fibrosis index based on the four factors), NLR (neutrophil-to-lymphocyte ratio), AAR (aspartate aminotransferase/alanine aminotransferase ratio) and RPR (red cell distribution width-to-platelet ratio) in HBeAg positive CHB and HBeAg negative CHB. We found AUROCs of GPR in predicting significant liver fibrosis, advanced liver fibrosis and liver cirrhosis were 0.732 (95% CI 0.663 to 0.801), 0.788 (95% CI 0.729 to 0.847) and 0.753 (95% CI 0.692 to 0.814), respectively. Further comparisons showed the diagnostic performance of GPR was not significantly different with APRI, FIB-4 and RPR in identifying significant fibrosis, advanced fibrosis and cirrhosis, but it was significantly superior to AAR and NLR in both HBeAg positive CHB and HBeAg negative CHB. In conclusion, GPR does not show advantages than APRI, FIB-4 and RPR in identifying significant liver fibrosis, advanced liver fibrosis and liver cirrhosis in both HBeAg positive CHB and HBeAg negative CHB in China.

Abstract
Objectives Noninvasive models have been established for the assessment of liver fibrosis in patients with chronic hepatitis B(CHB). However, the predictive performance of these established models remains inconclusive. We aimed to develop a novel predictive model for liver fibrosis in CHB based on routinely clinical parameters. Results Platelets(PLT), the standard deviation of red blood cell distribution width(RDW-SD), alkaline phosphatase(ALP) and globulin were independent predictors of significant fibrosis by multivariable analysis. Based on these parameters, a new predictive model namely APRG(ALP/PLT/RDW-SD/globulin) was proposed. The areas under the receiver-operating characteristic curves(AUROCs) of APRG index in predicting significant fibrosis(≥F2), advanced fibrosis(≥F3) and liver cirrhosis(≥F4) were 0.757(95%CI 0.699 to 0.816), 0.763(95%CI 0.711 to 0.816) and 0.781(95%CI 0.728 to 0.835), respectively. The AUROCs of the APRG were significantly higher than that of aspartate transaminase(AST) to PLT ratio index(APRI), RDW to PLT ratio(RPR) and AST to alanine aminotransferase ratio(AAR) to predict significant fibrosis, advanced fibrosis and cirrhosis. The AUROCs of the APRG were also significantly higher than fibrosis-4 score (FIB-4) (0.723, 95%CI 0.663 to 0.783) for cirrhosis(P=0.034) and better than gamma-glutamyl transpeptidase(GGT) to PLT ratio(GPR) (0.657, 95%CI 0.590 to 0.724) for significant fibrosis(P=0.001). Materials and Methods 308 CHB patients who underwent liver biopsy were enrolled. The diagnostic values of the APRG for liver fibrosis with other noninvasive models were compared. Conclusions The APRG has a better diagnostic value than conventionally predictive models to assess liver fibrosis in CHB patients. The application of APRG may reduce the need for liver biopsy in CHB patients in clinical practice.

Abstract
Chronic hepatitis B virus (HBV) infection is a major cause of liver morbidity and mortality worldwide. While a proportion of the 250 million individuals chronically infected with HBV will not come to significant harm or require therapy, many others risk developing complications of the end-stage liver disease such as decompensated cirrhosis and hepatocellular carcinoma (HCC), without intervention. Due to the complex natural history of HBV infection, patients require an expert assessment to interpret biochemistry, viral serology and appropriately stage the disease, and to initiate monitoring and/or therapy where indicated. The detection and quantification of liver fibrosis is a key factor for disease management and prognostication for an individual with HBV. The reliance on invasive liver biopsy to stage disease is diminishing with the advent of robust non-invasive blood- and imaging-based algorithms which can reliably stage disease in many cases. These tests are now incorporated into International guidelines for HBV management and relied upon daily to inform clinical judgement. Both blood- and imaging-based approaches have advantages over liver biopsy, including minimal risks, lower cost, better patient acceptance and speed of results, while disadvantages include lower diagnostic accuracy in intermediate disease stages and variability with co-existing hepatic inflammation or steatosis. This review outlines the methods of fibrosis assessment in chronic HBV infection and focuses on the most commonly used blood- and imaging-based non-invasive tests, reviewing their diagnostic performance and applicability to patient care.

Abstract
OBJECTIVES Liver biopsy remains the reference standard for the assessment of liver fibrosis, but this procedure is invasive and can lead to complications. Thus, studies to determine the optimal noninvasive test are warranted. This study compared several noninvasive tests and their combinations for evaluating liver fibrosis stages in patients with chronic hepatitis B. METHODS The shear wave velocity (SWV) and laboratory indicators were collected from 174 patients with chronic hepatitis B. Formulas were applied to calculate the serum fibrosis model, including the aspartate aminotransaminase-to-platelet ratio index (APRI), fibrosis-4 index (FIB-4) and aspartate aminotransferase-to-alanine aminotransferase ratio (AAR). The diagnostic performance of all noninvasive tests was assessed in comparison with percutaneous liver biopsy, based on a receiver operating characteristic curve analysis. RESULTS The SWV (area under the receiver operating characteristic curve [AUC], 0.82) and APRI (AUC = 0.77) performed better than the FIB-4 (AUC = 0.62), and the AAR (AUC = 0.47) was not suitable for evaluating substantial liver fibrosis (stage ≥F2). The SWV (AUC = 0.96) was the best indicator, being superior to the APRI (AUC = 0.75) and FIB-4 (AUC = 0.74), and the AAR (AUC = 0.45) was not suitable for assessing cirrhosis (F4). Combining the SWV and APRI, the AUC improved to 0.85 for substantial liver fibrosis, and the sensitivity increased to 100% for cirrhosis. CONCLUSIONS The SWV, APRI, and FIB-4 were valid tests for evaluating substantial liver fibrosis and cirrhosis. The combination of these tests with several noninvasive indicators is expected to enhance the assessment of liver fibrosis stages.

Hepatitis C virus infection stimulates transforming growth factor-β1 expression through up-regulating miR-192. J Microbiol 2016; 54:520-6. [PMID: 27350618 DOI: 10.1007/s12275-016-6240-3] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2016] [Revised: 06/07/2016] [Accepted: 06/07/2016] [Indexed: 12/22/2022]
Abstract
The objective of this study was to determine the molecular mechanisms underlying chronic liver injury and fibrosis caused by hepatitis C virus (HCV). This study revealed that miR-192 expreßsion was induced by HCV infection without affecting viral replication. However, viral-induced miR-192 up-regulated transforming growth factor-ß1 (TGF-ß1) expreßsion in liver cells at transcriptional level. TGF-ß1 stimulation by HCV-induced miR-192 was caused through ZEB1 down-regulation and TGF-ß1 increased miR-192 level via positive feedback pathway. Increase in miR-192 expreßsion by HCV infection was due to HCV core protein released and/or expressed by viral infection. TGF-ß1 promoter activity was also increased by HCV core protein in liver cells. Taken together, HCV infection resulted in increased TGF-ß1 transcription in hepatocytes through ZEB1 down-regulation by HCV core-mediated miR-192 stimulation. Importantly, miR-192 inhibition with anti-miR-192 rescued ZEB1 expression down-regulated by HCV infection, thus reducing the level of TGF-ß1 expression increased by HCV infection in hepatocytes. These results suggest a novel mechanism of HCV-mediated liver fibrogenesis with miR-192 being a potential molecular target to ameliorate viral pathogenesis.
