Abstract
To investigate the prognostic role of the elevated aspartate and alanine aminotransferase (AST/ALT) ratio in patients with unstable angina (UA). In this observational study, all patients with UA undergoing percutaneous coronary intervention at our center from January 2019 to December 2020 were examined. Clinical presentations, laboratory parameters, and procedural characteristics were collected. The primary endpoint was a composite of major adverse cardio-cerebral events (MACCE), such as death, nonfatal myocardial infarction, nonfatal stroke, and target vessel revascularization. In total, 1123 eligible UA patients were enrolled in the present study (mean age 62.3 years; 54.5% of male). Patients in the upper tertile of the AST/ALT ratio were older, had more extensive coronary stenosis, and had poor nutritional status (P < .05). Meanwhile, the cumulative incidence of MACCE at 13 months of follow-up increased in a stepwise manner and across the tertile of the AST/ALT ratio, predominantly driven by target vessel revascularization (both log-rank P < .001). Importantly, the AST/ALT ratio was associated with MACCE in a multivariate analysis that was adjusted for potential covariates (hazard ratio 1.72, 95% confidence interval 1.48-1.99, P < .01). The optimal cutoff point of the AST/ALT ratio to predict MACCE was 1.29 (area under the curve 0.77, 95% confidence interval 0.69-0.84, P < .001), with sensitivity and specificity of 77.5% and 65.1%, respectively. The increased AST/ALT ratio, especially when above 1.29, is associated with MACCE in patients with UA undergoing percutaneous coronary intervention.

Kwong AJ, Zahr NM. Serum biomarkers of liver fibrosis identify globus pallidus vulnerability. Neuroimage Clin 2023; 37:103333. [PMID: 36868044 PMCID: PMC9996367 DOI: 10.1016/j.nicl.2023.103333] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 01/12/2023] [Accepted: 01/19/2023] [Indexed: 01/28/2023]
Abstract
The CNS manifestation of chronic liver disease can include magnetic resonance (MR) signal hyperintensities in basal ganglia structures. Here, relations between liver (serum-derived fibrosis scores) and brain (regional T1-weighted signal intensities and volumes) integrity were evaluated in a sample of 457 individuals including those with alcohol use disorders (AUD), people living with human immunodeficiency virus (HIV), those comorbid for AUD and HIV, and healthy controls. Liver fibrosis was identified from cutoff scores as follows: aspartate aminotransferase to platelet ratio index (APRI) > 0.7 in 9.4% (n = 43) of the cohort; fibrosis score (FIB4) > 1.5 in 28.0% (n = 128) of the cohort; and non-alcoholic fatty liver disease fibrosis score (NFS) > -1.4 in 30.2% (n = 138) of the cohort. Presence of serum-derived liver fibrosis was associated with high signal intensities selective to basal ganglia (i.e., caudate, putamen, and pallidum) structures. High signal intensities in the pallidum, however, explained a significant portion of the variance in APRI (25.0%) and FIB4 (23.6%) cutoff scores. Further, among the regions evaluated, only the globus pallidus showed a correlation between greater signal intensity and smaller volume (r = -0.44, p <.0001). Finally, higher pallidal signal intensity correlated worse ataxia (eyes open ρ = -0.23, p =.0002; eyes closed ρ = -0.21, p =.0005). This study suggests that clinically relevant serum biomarkers of liver fibrosis such as the APRI may identify individuals vulnerable to globus pallidus pathology and contribute to problems with postural balance.

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.

Abstract
AIM It was to assess the diagnostic performance characteristics of a novel index, (ABA), which utilizes age, bilirubin and albumin to predict significant and severe fibrosis, and cirrhosis in patients with chronic hepatitis C infection. METHODS A total of 114 patients were included in this study. The liver biopsies were graded using the Ishak scoring system. Diagnostic performance of the ABA index was compared to aspartate aminotransferase (AST) to alanine aminotransferase ratio, age platelet index, AST to platelet ratio index, γ-glutamyl transpeptidase (GGT) to platelet ratio index, FIB-4, FibroQ, Goteborg University Cirrhosis Index, King's score, GGT/international normalization ratio, platelet to lymphocyte ratio, neutrophil to lymphocyte ratio, white blood cell to platelet distribution width ratio and mean platelet volume to platelet distribution width ratio (MPV/PDW) by receiver operating characteristics (ROC) curve analysis. RESULTS The ABA index was formulated as 1.5 + (0.065 × age) + (1.85 × bilirubin) - (1.65 × albumin) according to the multivariate logistic regression analysis. According to the ROC curve analyses, the ABA index had the area under these ROC curves (AUROCs) of 0.805 [95% confidence interval (CI), 0.727-0.883] for significant fibrosis, 0.874 (95% CI, 0.804-0.943) for severe fibrosis and 0.895 (95% CI, 0.828-0.961) for cirrhosis. CONCLUSION The ABA index was found to be superior to other evaluated noninvasive indexes of liver fibrosis by use of the cutoff point of 0 and 1. These findings should be confirmed by prospective and multicenter studies in patients with chronic hepatitis C infection.

Abstract
Classical inflammation in response to bacterial, parasitic, or viral infections such as HIV includes local recruitment of neutrophils and macrophages and the production of proinflammatory cytokines and chemokines. Proposed biomarkers of organ integrity in Alcohol Use Disorders (AUD) include elevations in peripheral plasma levels of proinflammatory proteins. In testing this proposal, previous work included a group of human immunodeficiency virus (HIV)-infected individuals as positive controls and identified elevations in the soluble proteins TNFα and IP10; these cytokines were only elevated in AUD individuals seropositive for hepatitis C infection (HCV). The current observational, cross-sectional study evaluated whether higher levels of these proinflammatory cytokines would be associated with compromised brain integrity. Soluble protein levels were quantified in 86 healthy controls, 132 individuals with AUD, 54 individuals seropositive for HIV, and 49 individuals with AUD and HIV. Among the patient groups, HCV was present in 24 of the individuals with AUD, 13 individuals with HIV, and 20 of the individuals in the comorbid AUD and HIV group. Soluble protein levels were correlated to regional brain volumes as quantified with structural magnetic resonance imaging (MRI). In addition to higher levels of TNFα and IP10 in the 2 HIV groups and the HCV-seropositive AUD group, this study identified lower levels of IL1β in the 3 patient groups relative to the control group. Only TNFα, however, showed a relationship with brain integrity: in HCV or HIV infection, higher peripheral levels of TNFα correlated with smaller subcortical white matter volume. These preliminary results highlight the privileged status of TNFα on brain integrity in the context of infection.

Abstract
Background Assessment of liver disease severity in chronic Hepatitis C (CHC) is essential both in pretreatment and posttreatment period. We assessed the impact of direct-acting antiviral therapy on liver stiffness regression measured by Vibration Controlled Transient Elastography (VCTE) in patients with CHC and evaluated the diagnostic performance of the APRI and FIB-4 scores compared to VCTE in detecting advanced fibrosis and cirrhosis (F3/F4). Methodology Retrospective analysis of consecutive patients with CHC who underwent VCTE before and after DAA therapy was done. APRI and FIB-4 scores were compared to VCTE. Results 88 (56.78%) patients-12 (F3) and 76 (F4) according to VCTE, had advanced fibrosis pretreatment, which reduced to 69 (44.52%) - 10 (F3) and 59 (F4) after 12 weeks DAA therapy. Significant reduction in VCTE value from 14.08 ± 9.05 KPa to 11.84 ± 8.31 KPa (p=0.002) was noted. There is significant reduction in APRI, FIB-4 and GUCI score posttreatment which was not the case with Lok score and Bonacini score. Before therapy, FIB-4 outperformed others to predict advanced fibrosis with score >2.13 (AUC 0.93), having sensitivity 76%, specificity 96% and accuracy 86%. However posttreatment, APRI and GUCI score performed best to predict F3/F4 fibrosis with score >0.63 (AUC 0.97) and >0.64 (AUC 0.96), having sensitivity, specificity and accuracy of 85%, 96.6% and 92% ; 85%, 6.6% and 92% respectively. Conclusion Before therapy, FIB-4 had the best accuracy in predicting advanced fibrosis whereas APRI and GUCI score were the best indices post-treatment.

Abstract
BACKGROUND Chronic hepatitis C (CHC) is a leading cause of liver fibrosis. OBJECTIVE To compare utility of liver transient elastography, AST-to-platelet ratio index (APRI), fibrosis-4 index (FIB4), Forns Index and Goteborg University cirrhosis index (GUCI) in predicting fibrosis stage assessed by liver biopsy in Egyptian CHC patients. METHODS One thousand two-hundred and seventy CHC patients undergoing liver biopsy in preparation for therapy and 40 healthy potential living liver donors had transient elastography and calculation of APRI, FIB4, Forns and GUCI scores on the same day or day preceding the biopsy. RESULTS Mean age was 39.89 (17-60 years) and most were males (70.7%). All donors had F0 fibrosis, most patients had F1-F2 fibrosis (n = 1011, 79.6%) and 259 (20.4%) had F3-F4 fibrosis. Patients with F3-F4 fibrosis had higher median values of APRI (0.99 vs. 0.46), FIB4 (2.15 vs. 0.95) and Forns (7.34 vs. 4.79) indices, GUCI score (1.16 vs. 0.49) and transient elastography (19.2 vs. 6.2 kPa) (all P = 0.001). For F1 discrimination, AUROC of transient elastography was higher than both Forns and GUCI scores (P = 0.001). APRI, FIB4 and GUCI had lower AUROC than transient elastography for predicting fibrosis stage in F2 and F3 patients (P = 0.001). Transient elastography had the best area under receiver operating characteristic curve for predicting fibrosis stage in F4 patients (P = 0.001). The transient elastography cutoff values (kPa) were F1 (>4.8), F2 (>8.3), F3 (>10.1) and F4 (>13.4). Age, APRI, FIB4, Forns, GUCI and transient elastography were independent predictors of F3-F4 fibrosis. CONCLUSION Liver elastography is superior to APRI, FIB4, Forns and GUCI scores in predicting fibrosis in CHC patients.

Abstract
Knowing the hepatic pathological features encountered in patients with chronic hepatitis C (CHC) and the fact that extrahepatic manifestations occur only in people with certain characteristics of the immune system, we tried to evaluate, qualitatively and semi-quantitatively, the liver pathological aspects encountered in 96 patients with CHC, previously untreated with Interferon (naïve), who showed or did not show signs of thyroid disorder (TD), hospitalized in the 2nd Medical Clinic of the Emergency County Hospital, Craiova, Romania, within a period of five years (2007-2012). Following hormonal, immunological, and thyroid ultrasound investigations, 14 (14.58%) of the 96 patients showed signs of TD. The main clinical forms of TD in the studied patients with CHC were autoimmune thyroiditis and subclinical hypothyroidism. In the patients with CHC with TD, we found mild chronic hepatitis in 14.28% of cases, the appearance of moderate chronic hepatitis was found in 71.42% patients, and the appearance of severe chronic hepatitis was found in 14.28% patients, while in the patients with CHC without TD we found chronic mild hepatitis in 62.19% of cases, the appearance of moderate chronic hepatitis was met in 32.92% patients, and the appearance of severe chronic hepatitis was found in 4.87% of patients. Mild and moderate fibrosis were found only in CHC patients without TD in a percentage of 25.6% and 65.85%, respectively, while severe fibrosis was found at 12.19% among CHC patients without TD and 92.85% among CHC patients with TD. The pathological aspect of liver cirrhosis was found only in those with TD (7.14%). In conclusion, the pathological features which define the liver necroinflammatory process, as encountered at the pathological examination in CHC patients with TD are the same as in any active chronic hepatitis, the differences being represented by the higher percentage of the periportal and the preseptal necrosis (piecemeal necrosis), as well as by the higher score of portal inflammation. In addition, the severe hepatic fibrosis and the histopathological appearance of the liver cirrhosis have only defined the cases of CHC with TD.

Abstract
Background Hepatic fibrosis grading is crucial for chronic hepatitis C (CHC) patients in monitoring liver disease progression and antiviral treatment indication. Retinol-binding protein 4 (RBP4), an adipokine secreted by adipocytes and hepatocytes, has variable levels in health and disease. Purpose To comparatively evaluate RBP4 serum levels in predicting liver fibrosis in CHC versus fibroscan, noninvasive fibrosis, and inflammatory indices. Patients and Methods Cohort study included 50 naive non-obese CHC patients and 20 age-, sex- and body mass index-matched healthy subjects. Fibroscan, RBP4, and noninvasive fibrosis as APRI, CDS, FIB-4, GUCI, Lok index indices based on serological markers, and inflammatory indices as platelet to lymphocyte ratio (PLR) and liver regeneration markers as; alpha-fetoprotein (AFP) and APRI, were evaluated in response to direct-acting antivirals (DAAs). Results RBP4 was significantly lower in patients than in controls (P=0.0001) and progressively decreased with the increase in fibrosis grade (F0-F=41.42±3.08), (F2=39.32±1.43), (F3-F4= 35.31±0.5), (P=0.0001). Liver function, stiffness, and RBP4 significantly improved after treatment (P=0.0001). RBP4 negatively correlated with viral load (r=−0.78, p=0.0001), fibroscan fibrosis grade (r=−0.52, p=0.0001), AFP (r=−0.63, p=0.0001), and positively correlated with platelet (r=0.424, p=0.0001), and white cell count (r=0.298, p=0.002). RBP4 at a cutoff value <40.55 ng/mL might predict significant fibrosis (90.48% sensitivity, 62.5% specificity, AUROC=0.811, 95% CI=67.5–90.0) and at a cutoff value <35.9 ng/mL could predict advanced fibrosis (100% sensitivity, 100% specificity, AUROC =1.0, 95% CI=0.929–1). Conclusion RBP4 showed excellent accuracy, sensitivity, specificity, PPV, and NPV. RBP4 has a superior diagnostic performance in predicting advanced fibrosis grads in CHC patients and hence can replace expensive invasive procedures.

Abstract
Background: Several studies have investigated certain fibrosis markers that incorporate liver function tests, fragments of liver-matrix components and/or degraded products generated by hepatic stellate cells for determining the degree of hepatic fibrosis. However, the role of these molecules in the development of hepatic fibrosis is unclear. This work aimed (a) to determine whether platelet-derived growth factor (PDGF) is linked to different stages of hepatic fibrosis and (b) investigate its diagnostic performance alongside other laboratory and demographic factors in assessing liver fibrosis in chronic hepatitis C infection. Methods: Liver-fibrosis was staged according to Fibroscan, PDGF quantified using ELISA, and liver function tests and other analytes determined by standard techniques in 239 patients with chronic hepatitis C virus infection. Results: Patients with significant (F2-F4), advanced fibrosis (F3-F4) and cirrhotic liver disease (F4) showed significantly (P<0.0001) higher PDGF levels increase respectively compared to stage F0/1. We used this to construct the PARA-Index (PDGF/albumin ratio, age), which performed well in assessing hepatic-fibrosis stages with AUCs of 0.91, 0.87 and 0.86 for identifying F2-F4, F3-F4 and F4, respectively. Additionally, the PARA-Index correlated strongly (r=0.65, P<0.0001) with the severity of the fibrosis. An elevated PARA-index provided odds ratios of 21.0, 20.7 and 10.3 for developing F2-F4, F3-F4 and F4, respectively. Conclusion: A panel of mitogenic (PDGF), biochemical (albumin) and demographical (age) parameters may improve liver-fibrosis staging with a high degree of accuracy in those with a hepatitis C virus infection.

Daclatasvir and Sofosbuvir Therapy Enhance Monocyte Phenotypic Changes in Naive Chronic Hepatitis C Patients: A Prospective Cohort Study. Interdiscip Perspect Infect Dis 2019; 2019:9469567. [PMID: 30941170 PMCID: PMC6420991 DOI: 10.1155/2019/9469567] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2018] [Accepted: 12/05/2018] [Indexed: 12/23/2022] Open
Abstract
Background Liver inflammation influences monocyte function, recruitment, and consequently inflammatory and fibrogenic responses. We aimed to investigate changes in the circulating monocyte phenotypes in response to Daclatasvir-Sofosbuvir (SOF/DCV) therapy in chronic hepatitis C (CHC) and relate findings to the viral kinetics and the fibrosis score. Methods A longitudinal study involving 100 treatment-naïve patients and 30 healthy controls, tested for liver function, fibrosis scores (AST to platelet ratio index, FIB-4), and blood monocyte subsets based on CD14/CD16 expression by flow cytometer. Results CHC patients had significantly lower albumin, higher ALT, AST, alkaline phosphatase, and increased fibrosis scores [Fib-4 (1.85±0.98) and AST to platelet ratio index (APRI) (0.6±0.35)], higher monocyte and eosinophil counts and lowered neutrophil to monocyte ratio (NMR), and lymphocyte to monocyte ratio (LMR) compared to week 12 and control. CHC patients had significantly increased median [classical (52.2% versus 25.8%, P=0.004) and inflammatory CD16+ monocytes (23.1% versus 13.58%, P=0.035)]. Therapy results in achievement of sustained virological response in 92% of cases, liver function improvement, and normalization of the inflammatory monocytes subsets. Monocyte counts showed positive correlation with viral load, calculated fibrosis scores (APRI and FIB-4 score), AST, ALT, ANC, and inverse correlations with serum albumin, leukocyte, eosinophil, NMR, and LMR. Multivariate regression found eosinophil count as predictors of CD16+ monocyte count in CHC patients. Conclusion CHC infection promotes a proinflammatory and profibrotic monocytes profile. SOF/DCV therapy efficiently decreases viral load, reduces fibrosis potentials, attenuates monocyte activation, normalizes monocytes phenotypic abnormalities, and modulates monocyte subsets recruitment and differentiation later in the liver.

Abstract
AIM To investigate the relationship of the aspartate aminotransferase to alanine aminotransferase ratio (AST/ALT) and metabolic syndrome (MetS) in adolescents in northeast China. METHODS A stratified cluster random sample of 935 students 11-16 years of age in a city in the northeast of China were enrolled in 2010-2011. Participants were given a physical examination and a laboratory evaluation, and 93 participants were followed-up after 5 years. RESULTS AST/ALT was negatively correlated with waist circumference (WC), waist-to-hip ratio, body mass index (BMI), diastolic blood pressure, triglycerides, low-density lipoprotein, uric acid, fasting insulin, and insulin resistance. It was positively correlated with high-density lipoprotein. Multivariate logistic regression showed that the risk of MetS was 6.02 times greater in adolescents with the lowest, compared with the highest, AST/ALT. Central obesity was the MetS component most closely associated with low AST/ALT [odds ratio (OR) =5.13, 95% CI: 2.83, 9.28]. Five years later, baseline AST/ALT was negatively correlated with WC (r=-0.21, P=0.046), BMI (r=-0.29, P=0.005) and fasting plasma glucose (r=-0.25, P=0.017). CONCLUSION In adolescents, AST/ALT was significantly associated with MetS and its components and predicted overweight/obesity in adulthood.

Abstract
Assessment of hepatic fibrosis in chronic hepatitis C virus patients by liver biopsy is not widely accepted despite its accuracy, being invasive, carrying complications, and adding cost. This paved the way to development and use of non-invasive markers of fibrosis in diagnosis of hepatic fibrosis. We aimed at evaluating the efficiency of Fib-4, Egy-score, Aspartate-to-platelet ratio index (APRI), and Göteborg University Cirrhosis Index (GUCI) in comparison to liver biopsy, in the assessment of hepatic fibrosis in chronic hepatitis C patients. This was a cross sectional study including 200 chronic HCV patients were divided into two groups according to stage of fibrosis (Metavir score) into non-significant fibrosis (<F2) and significant fibrosis (≥F2). Reference needle liver biopsy was compared to Fib-4, Egyscore, APRI, and GUCI. Older age (P < 0.001) and higher BMI (P = 0.005) were significantly related to significant fibrosis and positively correlated with fibrosis progression (r = 0.361, P = 0.000, and r = 0.165, P = 0.019 respectively). Fib-4 >1.27, APRI >0.48, Egy-score >0.73, and GUCI >0.57 significantly predict significant fibrosis (P < 0.01). Fib-4 carries the best performance and significant reliability with AUROC 0.783, sensitivity 74%, specificity 69%, PPV 0.55, and NPV 0.86. The addition of BMI to Fib-4 improved the significant fibrosis AUROC curve performance but did not reach statistical significant improvement. We concluded that age and BMI are good predictors of hepatic fibrosis. Fib-4 (>1.27) is the best method of prediction of significant fibrosis compared to Egy-score, APRI, and GUCI. Addition of BMI to Fib-4 did not improve diagnostic value of Fib-4.

Abstract
Substantial evidence supports the view that inflammatory processes contribute to brain alterations in HIV infection. Mechanisms recently proposed to underlie neuropathology in Alcohol Use Disorder (AUD) include elevations in peripheral cytokines that sensitize the brain to the damaging effects of alcohol. This study included 4 groups: healthy controls, individuals with AUD (abstinent from alcohol at examination), those infected with HIV, and those comorbid for HIV and AUD. The aim was to determine whether inflammatory cytokines are elevated in AUD as they are in HIV infection. Cytokines showing group differences included interferon gamma-induced protein 10 (IP-10) and tumor necrosis factor α (TNFα). Follow-up t-tests revealed that TNFα and IP-10 were higher in AUD than controls but only in AUD patients who were seropositive for Hepatitis C virus (HCV). Specificity of TNFα and IP-10 elevations to HCV infection status was provided by correlations between cytokine levels and HCV viral load and indices of liver integrity including albumin/globulin ratio, fibrosis scores, and AST/platelet count ratio. Because TNFα levels were mediated by HCV infection, this study provides no evidence for elevations in peripheral cytokines in "uncomplicated", abstinent alcoholics, independent of liver disease or HCV infection. Nonetheless, these results corroborate evidence for elevations in IP-10 and TNFα in HIV and for IP-10 levels in HIV+HCV co-infection.

Abstract
BACKGROUND AND AIM Many indirect noninvasive scores to predict liver fibrosis are calculated from routine blood investigations. Only limited studies have compared their efficacy head to head. We aimed to compare these scores with liver biopsy fibrosis stages in patients with chronic hepatitis C. MATERIALS AND METHODS From blood investigations of 1602 patients with chronic hepatitis C who underwent a liver biopsy before initiation of antiviral treatment, 19 simple noninvasive scores were calculated. The area under the receiver operating characteristic curves and diagnostic accuracy of each of these scores were calculated (with reference to the Scheuer staging) and compared. RESULTS The mean age of the patients was 41.8±9.6 years (1365 men). The most common genotype was genotype 4 (65.6%). Significant fibrosis, advanced fibrosis, and cirrhosis were seen in 65.1%, 25.6, and 6.6% of patients, respectively. All the scores except the aspartate transaminase (AST) alanine transaminase ratio, Pohl score, mean platelet volume, fibro-alpha, and red cell distribution width to platelet count ratio index showed high predictive accuracy for the stages of fibrosis. King's score (cutoff, 17.5) showed the highest predictive accuracy for significant and advanced fibrosis. King's score, Göteborg university cirrhosis index, APRI (the AST/platelet count ratio index), and Fibrosis-4 (FIB-4) had the highest predictive accuracy for cirrhosis, with the APRI (cutoff, 2) and FIB-4 (cutoff, 3.25) showing the highest diagnostic accuracy.We derived the study score 8.5 - 0.2(albumin, g/dL) +0.01(AST, IU/L) -0.02(platelet count, 10(9)/L), which at a cutoff of >4.7 had a predictive accuracy of 0.868 (95% confidence interval, 0.833-0.904) for cirrhosis. CONCLUSIONS King's score for significant and advanced fibrosis and the APRI or FIB-4 score for cirrhosis could be the best simple indirect noninvasive scores.

Abstract
BACKGROUND The aim of this study was to compare fourteen non-invasive indexes/scores: AAR, APRI, Fibroindex, MODEL3, Forns index, FIB4, GUCI, FI, FCI, Pohl score, AP index, CDS, HGM-1 and HGM-2, in order to diagnose the hepatic fibrosis stage in a survey of patients with chronic hepatitis C. METHODS 84 patients with chronic hepatitis C were studied. Liver fibrosis was staged according to the Scheuer scoring system. The diagnostic accuracy of these indexes/scores was evaluated by AUROC, contingency tables and logistic regression analysis. RESULTS The best AUROCs (>0.9) to discriminate cirrhosis (F=4), were observed for CDS, FI, AAR, MODEL3, FIB4, HGM-2 and FCI. To discriminate at least advance fibrosis (F≥3), the best AUROCs (>0.89) were for CDS, FI, FIB4, HGM2-2, MODEL3 and FCI. To discriminate at least significant fibrosis (F≥2), the best AUROCs (>0.8) were for FIB4, GUCI, APRI, FI, Forns index, HGM-2 and FCI. Contingency tables and logistic regression analysis supported the results obtained by AUROC. CONCLUSIONS This study compares the diagnostic performance of fourteen indexes for the diagnosis of liver fibrosis stage in the same group of CHC patients. These results allow the selection of the best indexes for further studies in larger populations, in order to build diagnostic algorithms as an alternative to liver biopsy for fibrosis staging in patients with chronic HCV infection. These algorithms would allow to take therapeutical decisions and the continuous follow-up of hepatic fibrosis in these patients.

Abstract
Aim To compare the performance of several simple, noninvasive models comprising various serum markers in diagnosing significant liver fibrosis in the same sample of patients with chronic hepatitis B (CHB) with the same judgment standard. Methods A total of 308 patients with CHB who had undergone liver biopsy, laboratory tests, and liver stiffness measurement (LSM) at the Southwest Hospital, Chongqing, China between March 2010 and April 2014 were retrospectively studied. Receiver operating characteristic (ROC) curves and area under ROC curves (AUROCs) were used to analyze the results of the models, which incorporated age-platelet (PLT) index (API model), aspartate transaminase (AST) to alanine aminotransferase (ALT) ratio (AAR model), AST to PLT ratio index (APRI model), γ-glutamyl transpeptidase (GGT) to PLT ratio index (GPRI model), GGT-PLT-albumin index (S index model), age-AST-PLT-ALT index (FIB-4 model), and age-AST-PLT-ALT-international normalized ratio index (Fibro-Q model). Results The AUROCs of the S index, GPRI, FIB-4, APRI, API, Fibro-Q, AAR, and LSM for predicting significant liver fibrosis were 0.726 (P < 0.001), 0.726 (P < 0.001), 0.621 (P = 0.001), 0.619 (P = 0.001), 0.580 (P = 0.033), 0.569 (P = 0.066), 0.495 (P = 0.886), and 0.757 (P < 0.001), respectively. The S index and GPRI had the highest correlation with histopathological scores (r = 0.373, P < 0.001; r = 0.372, P < 0.001, respectively) and LSM values (r = 0.516, P < 0.001; r = 0.513, P < 0.001, respectively). When LSM was combined with S index and GPRI, the AUROCs were 0.753 (P < 0.001) and 0.746 (P < 0.001), respectively. Conclusion S index and GPRI had the best diagnostic performance for significant liver fibrosis and were robust predictors of significant liver fibrosis in patients with CHB for whom transient elastography was unavailable.

Abstract
OBJECTIVE To evaluate the effectiveness of certain noninvasive liver-damage markers in predicting liver diseases and the clinical severity of liver cirrhosis. METHODS We tested serum specimens from 57 patients with alcoholic cirrhosis, 30 with nonalcoholic cirrhosis, and 22 with toxic hepatitis (TH). The Bonacini, King, and Göteborg University Cirrhosis Index (GUCI) scores were calculated using specific formulas. RESULTS The values of the Bonacini and King scores significantly differ between liver diseases. The Bonacini score was higher in alcoholic and nonalcoholic cirrhosis than in TH, and the King score was higher in alcoholic cirrhosis than in TH. All of the tested scores appeared to vary according to the severity of liver damage and were higher in Child-Pugh class C than that in classes A and B. CONCLUSIONS We conclude that the Bonacini and King scores differ between liver diseases and that all the tested scores reflect the severity of liver cirrhosis.

Abstract
The aims of this study are to present the results of Egyptian RA patients included in COMORA cohort and compare it to general COMORA cohort, concerning prevalence of comorbidities, and level of application of recommendations related to detection/prevention of comorbidities. Three-hundred eight Egyptian RA patients included in the cross-sectional, observational, multi-center, international study "COMORA", were compared to the total number of 3612 RA patients. The CRF of COMORA was used in all patients. CRF collects demographic and disease characteristics, comorbidities, risk factors, and compliance with recommendations regarding management of comorbidities. Data were analyzed according to COMORA protocol. Egyptian RA patients were significantly younger, had more active disease, and were more functionally disabled. They showed more frequent use of NSAIDs, methotrexate and steroids and significantly lower use of bDMARDs when compared to non-Egyptians. Egyptian patients had the highest ever HCV prevalence, while depression, hypertension, smoking and dyslipidemia were less prevalent in Egyptians. Prevalence of malignancy risk factors was highly deficient among Egyptians; primarily due to lack of screening. Further, following recommendations for monitoring comorbidities is significantly deficient among Egyptian patients. Egyptian patients had more active disease and more functional impairment than the rest of the COMORA cohort; with lower use of bDMARDs, that is possibly related to the economic situation. Also, there is a clear gap in screening and monitoring comorbidities. Awareness among Egyptian healthcare providers (and possibly similar third-world countries) to detect and manage RA-related comorbidities is required.

Abstract
BACKGROUND AND AIM Noninvasive tests are primarily used for staging hepatic fibrosis in patients with chronic liver disease. In clinical practice, serum aminotransferase levels, coagulation parameters, and platelet count have been used to predict whether or not a patient has cirrhosis. In addition, several studies have evaluated the accuracy of combinations (or ratios) of these measures. The present study aimed to investigate the relationship between five noninvasive models [AST/ALT ratio (AAR), aspartate aminotransferase to platelet ratio index (APRI), Bonacini cirrhosis discriminant score (CDS), age-platelet index (APind), and King's score] and the degree of hepatic fibrosis as determined by biopsy in patients with chronic hepatitis B and C. PATIENTS AND METHODS A total of 380 patients with viral hepatitis (237 with chronic hepatitis B and 143 with chronic hepatitis C) who were seen at our clinic between January 2005 and January 2011 were retrospectively analyzed. The degree of fibrosis was determined using the Ishak score. Patients with a fibrosis score of 0-2 were considered to have low fibrosis and those with a score between 3 and 6 were considered to have high fibrosis. Five noninvasive models were compared between the groups with low and high fibrosis. RESULTS There were statistically significant differences between the hepatitis B and C patients with high and low fibrosis with respect to APind (4.49±2.35 vs. 2.41±1.84; P<0.001 in hepatitis B and 4.83±2.25 vs. 2.92±1.88; P<0.001 in hepatitis C), APRI (1.00±1.17 vs. 0.47±0.39; P<0.001 in hepatitis B and 1.01±1.01 vs. 0.41±0.29; P<0.001 in hepatitis C), CDS (4.53±1.90 vs. 3.58±1.30; P<0.001 in hepatitis B and 4.71±2.03 vs. 3.42±1.49; P<0.05 in hepatitis C), and King's score (24.31±3.14 vs. 7.65±6.70; P<0.001 in hepatitis B and 24.82±2.55 vs. 8.33±7.29; P<0.001 in hepatitis C). There were no significant differences in the AAR between the hepatitis B and C patients with high and low fibrosis (0.78±0.31 vs. 0.74±0.34; P=0.082 in hepatitis B and 0.91±0.40 vs. 0.85±0.27; P=0.25 in hepatitis C). The area under the receiver-operating characteristic curve of the APind, APRI, CDS, and King's score in the hepatitis B group were 0.767, 0.710, 0.646, and 0.770, respectively; these values were 0.732, 0.763, 0.677, and 0.783, respectively, in the hepatitis C group. CONCLUSION In conclusion, our data suggest that four of the five noninvasive methods evaluated in this study can be used to predict advanced fibrosis in patients with hepatitis B and C. However, there was no significant relationship between the degree of hepatic fibrosis and the AAR score, indicating that AAR is not useful in estimating the fibrosis stage in hepatitis B and C patients.

Abstract
BACKGROUND Several noninvasive tests have been developed to determine the degree of hepatic fibrosis in patients with chronic hepatitis C (CHC) without performing liver biopsy. AIM This study aimed to determine the performance of the PAPAS (Platelet/Age/Phosphatase/AFP/AST) index in patients with CHC for the prediction of significant fibrosis and cirrhosis and to compare it with other noninvasive tests. To date, no study has evaluated the application of the PAPAS index in CHC-associated liver fibrosis. MATERIALS AND METHODS This retrospective study included 137 consecutive patients with CHC who had undergone a percutaneous liver biopsy before treatment. The aspartate aminotransferase/platelet ratio (APRI), aspartate aminotransferase/alanine transaminase ratio (AAR), age-platelet index (API), FIB4, cirrhosis discriminate score (CDS), the Göteborg University cirrhosis index (GUCI), and PAPAS were calculated and compared with the diagnostic accuracies of all fibrosis indices between the groups F0-F2 (no-mild fibrosis) versus F3-F6 (significant fibrosis) and F0-F4 (no cirrhosis) versus F5-F6 (cirrhosis). RESULTS To predict significant fibrosis, the area under curve (95% confidence interval) for FIB4 was 0.727 followed by GUCI (0.721), PAPAS≈APRI≈CDS (0.716), and API (0.68). To predict cirrhosis, the area under curve (95% confidence interval) for FIB4 was calculated to be 0.735, followed by GUCI (0.723), PAPAS≈APRI≈CDS≈(0.71), and API (0.66). No statistically significant difference was observed among these predictors to exclude both significant fibrosis and cirrhosis (P>0.05). CONCLUSION The diagnostic capability of the PAPAS index has moderate efficiency and was not superior to other fibrosis markers for the identification of fibrosis in CHC patients. There is a need for more comprehensive prospective studies to help determine the diagnostic value of PAPAS for liver fibrosis.

Abstract
INTRODUCTION Chronic hepatitis is specified as inflammatory disease of the liver lasting for more than six months. Role of noninvasive fibrosis markers as prognostication factors of the presence or absence of significant fibrosis on liver biopsy of patients with chronic hepatitis is the aim of this study. METHODS Two hundred twenty-one patients with chronic hepatitis involved in the study between 2011 and 2013. Routine biochemical indices and serum fibrosis markers such as aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR), AST to platelet ratio index (APRI) and Fibrosis 4 score (FIB-4) were evaluated, and the histological grade and stage of the liver biopsy specimens were scored according to the Ishak scoring system. Diagnostic accuracies of these markers for prediction of significant fibrosis were assessed by Receiver Operating Characteristic (ROC) curve analysis. RESULTS Contemporaneous laboratory indices for imputing AAR, APRI, and FIB-4 were identified with liver biopsies. From all, 135 males (61.1%) and 86 females (38.9%), with mean age of 39.6±14.4 were studied. Significant correlation between stages of fibrosis and FIB-4, APRI and AAR were detected, with a correlation coefficient higher than that of other markers in the patients with Hepatitis B (r = 0.46), C (r = 0.58) and autoimmune hepatitis (r = 0.28). FIB-4 (AUROC = 0.84) and APRI (AUROC = 0.78) were superior to AAR at distinguishing severe fibrosis from mild-to-moderate fibrosis and gave the highest diagnostic accuracy. CONCLUSION Application of these markers was good at distinguishing significant fibrosis and decreased the need for staging liver biopsy specimens among patients with chronic hepatitis.

Abstract
Liver cirrhosis is one of the leading causes of death worldwide. Liver biopsy is considered as the gold standard for the diagnosis of chronic liver diseases. Studies have focused on non-invasive markers for liver fibrosis because of the dangers and complications of liver biopsy. The authors review the non-invasive direct as well as indirect methods for liver fibrosis assessment and present the positive and negative predictive value, sensitivity and specificity of those. Clinical utilities of transient elastography (Fibrsocan) is also reviewed. Non-invasive methods are useful in the assessment of liver fibrosis, monitoring disease progression and therapeutic response. Their accuracy can be increased by the combined or sequential use of non-invasive markers. Orv. Hetil., 2015, 156(2), 43–52.

Abstract
AIMS Staging for liver fibrosis is recommended in the management of hepatitis C as an argument for treatment priority. Our aim was to construct a noninvasive algorithm to predict the significant liver fibrosis (SLF) using common biochemical markers and compare it with some existing models. METHODS The study group included 104 consecutive cases; SLF was defined as Ishak fibrosis stage greater than 2. The patient population was assigned randomly to the training and the validation groups of 52 cases each. The training group was used to construct the algorithm from parameters with the best predictive value. Each parameter was assigned a score that was added to the noninvasive fibrosis score (NFS). The accuracy of NFS in predicting SLF was tested in the validation group and compared with APRI, FIB4, and Forns models. RESULTS Our algorithm used age, alkaline phosphatase, ferritin, APRI, α2 macroglobulin, and insulin and the NFS ranged from -4 to 5. The probability of SLF was 2.6 versus 77.1% in NFS<0 and NFS>0, leaving NFS=0 in a gray zone (29.8% of cases). The area under the receiver operating curve was 0.895 and 0.886, with a specificity, sensitivity, and diagnostic accuracy of 85.1, 92.3, and 87.5% versus 77.8, 100, and 87.9% for the training and the validation group. In comparison, the area under the receiver operating curve for APRI=0.810, FIB4=0.781, and Forns=0.703 with a diagnostic accuracy of 83.9, 72.3, and 62% and gray zone cases in 46.15, 37.5, and 44.2%. CONCLUSION We devised an algorithm to calculate the NFS to predict SLF with good accuracy, fewer cases in the gray zone, and a straightforward clinical interpretation. NFS could be used for the initial evaluation of the treatment priority.

Impact of contacting study authors to obtain additional data for systematic reviews: diagnostic accuracy studies for hepatic fibrosis. Syst Rev 2014; 3:107.

Abstract
BACKGROUND Seventeen of 172 included studies in a recent systematic review of blood tests for hepatic fibrosis or cirrhosis reported diagnostic accuracy results discordant from 2 × 2 tables, and 60 studies reported inadequate data to construct 2 × 2 tables. This study explores the yield of contacting authors of diagnostic accuracy studies and impact on the systematic review findings. METHODS Sixty-six corresponding authors were sent letters requesting additional information or clarification of data from 77 studies. Data received from the authors were synthesized with data included in the previous review, and diagnostic accuracy sensitivities, specificities, and positive and likelihood ratios were recalculated. RESULTS Of the 66 authors, 68% were successfully contacted and 42% provided additional data for 29 out of 77 studies (38%). All authors who provided data at all did so by the third emailed request (ten authors provided data after one request). Authors of more recent studies were more likely to be located and provide data compared to authors of older studies. The effects of requests for additional data on the conclusions regarding the utility of blood tests to identify patients with clinically significant fibrosis or cirrhosis were generally small for ten out of 12 tests. Additional data resulted in reclassification (using median likelihood ratio estimates) from less useful to moderately useful or vice versa for the remaining two blood tests and enabled the calculation of an estimate for a third blood test for which previously the data had been insufficient to do so. We did not identify a clear pattern for the directional impact of additional data on estimates of diagnostic accuracy. CONCLUSIONS We successfully contacted and received results from 42% of authors who provided data for 38% of included studies. Contacting authors of studies evaluating the diagnostic accuracy of serum biomarkers for hepatic fibrosis and cirrhosis in hepatitis C patients impacted conclusions regarding diagnostic utility for two blood tests and enabled the calculation of an estimate for a third blood test. Despite relatively extensive efforts, we were unable to obtain data to resolve discrepancies or complete 2 × 2 tables for 62% of studies.

Abstract
According to the World Health Organization, liver cirrhosis accounted for 1.8% of all deaths in Europe, causing about 170,000 deaths per year. Approximately 29 million persons in the EU suffer from chronic liver disease and this trend is on the rise. Liver disease is the EU's fifth most common cause of death accounting for at least one in six deaths. Early detection and monitoring of fibrosis has the potential to direct management of these chronic liver diseases and avert morbidity and mortality. Although the available techniques are in their infancy and the very early stages of fibrosis are difficult to detect, there have been significant advances in imaging over the last decade that has resulted in the use of these new imaging techniques being introduced into the patient pathway. This review explores the accuracies of these imaging techniques, their role in the management of patients, and the potential for the future.

Abstract
BACKGROUND Liver biopsy is gold standard for fibrosis assessment in hepatitis C virus (HCV) infection but its limitations led to the identification of non-invasive biomarkers. This study assesses the reliability of five biomarkers in estimating the stage of liver fibrosis/cirrhosis in chronic HCV patients versus METAVIR scoring. METHODS One hundred HCV monoinfected patients who underwent liver biopsy and blood sampling were included. Liver fibrosis was staged (F0-4) and required laboratory tests were performed. AAR, API, APRI, FIB-4 and Pohl score were calculated and their receiver operating curves (ROCs), sensitivities, specificities, predictive values and accuracies were evaluated. RESULTS There were 27, 44, and 29 patients at F0-F1, F2-F3, and F4 groups. Significant statistical differences were found regarding AST, vireamia, platelet count, prothrombin time and all biomarkers. From ROCs only Pohl score predicted significant fibrosis and cirrhosis but with low accuracy. AAR, API and APRI showed moderate performance at low cut-offs, but had limited predictive values or accuracies at higher cut-offs. FIB-4 was the least accurate test. The diagnostic reliability of these biomarkers was limited to patients with suspected insignificant fibrosis. CONCLUSIONS This study verified the limited reliability for AAR, API, APRI, FIB-4 and Pohl score in estimating the stage of hepatic fibrosis in HCV infected patients opposed to METAVIR scoring.

Abstract
Aims. To measure the effect of pegylated interferon-α therapy on serum activin-A, activin-B, and follistatin and their correlation with viral load and liver fibrosis in chronic hepatitis C (CHC). Methods. This study was cross-sectional and sera were collected from 165 participants classified into 7 groups: 40 healthy negative control, 33 treatment naïve patients as positive control, 19 patients at week 4, 22 at week 12, and 19 at week 24 of treatment initiation and 21 responders and 11 nonresponders at the end of 48-week treatment protocol. Serum candidate proteins were measured using ELISA and liver fibrosis was assessed by AST platelet ratio index (APRI). Results. CHC significantly increased activins and decreased follistatin compared to negative control (P < 0.05). Activin-A and follistatin levels returned to the levels of negative control group at weeks 4, 12, and 24 following treatment initiation and were significantly different from positive control (P < 0.05). Both proteins were significantly different between responders and nonresponders. Activin-A correlated positively and significantly with the viral load and APRI. Conclusion. CHC modulates serum activin-A and follistatin and they appear to be influenced by pegylated interferon-α therapy. Further studies are needed to explore the role of activins in CHC.

Abstract
BACKGROUND AND OBJECTIVES Heroin-dependent patients typically contract hepatitis C virus (HCV) at a disproportionately high level due to needle exchange. The liver is the primary target organ of HCV infection and also the main organ responsible for drug metabolism. Methadone maintenance treatment (MMT) is a major treatment regimen for opioid dependence. HCV infection may affect methadone metabolism but this has rarely been studied. In our current study, we aimed to test the hypothesis that HCV may influence the methadone dosage and its plasma metabolite concentrations in a MMT cohort from Taiwan. METHODS A total of 366 MMT patients were recruited. The levels of plasma hepatitis B virus (HBV), HCV, human immunodeficiency virus (HIV) antibodies (Ab), liver aspartate aminotransferase (AST) and alanine aminotransferase (ALT), as well as methadone and its metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) were measured along with the urine morphine concentration and amphetamine screening. RESULTS Of the 352 subjects in our cohort with HCV test records, 95% were found to be positive for plasma anti-HCV antibody. The liver functional parameters of AST (Wilcoxon Rank-Sum test, P = 0.02) and ALT (Wilcoxon Rank-Sum test, P = 0.04), the plasma methadone concentrations (Wilcoxon Rank-Sum test, P = 0.043) and the R-enantiomer of methadone concentrations (Wilcoxon Rank-Sum test, P = 0.032) were significantly higher in the HCV antibody-positive subjects than in the HCV antibody-negative patients, but not the S-EDDP/methadone dose ratio. The HCV levels correlated with the methadone dose (β= 14.65 and 14.13; P = 0.029 and 0.03) and the S-EDDP/methadone dose ratio (β= -0.41 and -0.40; P = 0.00084 and 0.002) in both univariate and multivariate regression analyses. CONCLUSIONS We conclude that HCV may influence the methadone dose and plasma S-EDDP/methadone dose ratio in MMT patients in this preliminary study.
