Abstract
IntroductionThe platelet count/spleen thickness ratio (PC/ST ratio) is associated with the grade of esophagogastric varices (EGV) in cirrhotic patients, but little is known about its relationship with esophagogastric variceal bleeding (EGVB). The aim of this study was to investigate the association between the PC/ST ratio and the risk of EGVB within 1 year in cirrhotic patients.MethodsA total of 1,354 patients with cirrhosis who had EGV were enrolled in this cohort study. A logistic regression model was used to determine the association between the PC/ST ratio and the risk of EGVB within 1 year in patients with cirrhosis by adjusting the PC/ST ratio with all the important clinical variables and confounders.ResultsThe quartile values of the PC/ST ratio were 1.01, 1.36, and 1.98, respectively. The PC/ST ratio was an independent risk factor for variceal bleeding in cirrhotic patients with moderate or severe EGV. After adjusting for multiple variables, the relationship was still unchanged. The odds ratios of the first EGVB in these patients were 5.07-fold at non-adjustment and 3.28-fold after multivariate adjustment. The odds ratios of rebleeding in these patients from the lowest to the highest quartile were 2.34-fold at non-adjustment and 2.01-fold after multivariable adjustment. The PC/ST ratio ≤ 1.36 elevated the 1-year risk of first-time variceal bleeding or rebleeding in cirrhotic patients with moderate or severe EGV (All P < 0.05).ConclusionThe PC/ST ratio ≤ 1.36 is an independent risk factor for the onset of first bleeding or rebleeding in cirrhotic patients with moderate or severe EGV.

Abstract
BACKGROUND Biliary atresia is a progressive obliterative cholangiopathy affecting both extrahepatic and intrahepatic biliary trees, resulting in fibrous obliteration of the biliary tract and subsequent development of cirrhosis. OBJECTIVE The aim of this study was to find noninvasive indices to predict the status of hepatic fibrosis in children with biliary atresia. MATERIALS AND METHODS We retrospectively measured the volume of the hepatic lobes and spleen from MR images, obtained biochemical data and analyzed the relationship between the imaging and biochemical indices, and the pathological status of hepatic fibrosis in 35 children with biliary atresia. RESULTS A combined index was obtained by logistic regression: logit (likelihood of cirrhosis) = 0.00043 x age at MR examination + 1.67 x aspartate aminotransferase and platelet ratio index (APRI) + 0.0029 x body-surface-area-adjusted left liver lobe volume (BSA adLLV) - 6.57 (log-likelihood chi-square P<0.05, pseudo-R2=0.59). The area under the receiver operator characteristic curve of age at MR examination, APRI, BSA adLLV and the combined index for prediction of cirrhosis were 0.91, 0.86, 0.83 and 0.94, respectively. The optimal cut-off value (sensitivity and specificity) of age at MR examination, APRI, BSA adLLV and combined index were 132 (86% and 92%), 1.3 (91% and 85%), 855.5 (96% and 62%) and 0.689 (91% and 92%). The accuracy of age at MR examination, APRI, BSA adLLV and combined index were 89%, 89%, 83% and 91%, respectively. CONCLUSION A combined noninvasive index of age, aspartate aminotransferase and platelet ratio index, and the body-surface-area-adjusted left liver lobe volume measured from MR images is a potential marker of liver cirrhosis in children with biliary atresia.

Abstract
Variceal bleeding is a dramatic complication of cirrhosis. Primary prophylaxis against variceal bleeding is indicated for patients with high-risk varices. In order for these patients to be identified, endoscopic screening for esophageal varices has been traditionally recommended at the time of the diagnosis of cirrhosis. Considering that many patients do not have esophageal varices in the early stages of cirrhosis and, therefore, are submitted to endoscopy unnecessarily, non-invasive methods for variceal screening have been studied. Among these non-invasive methods, the most extensively studied probably are platelet count/spleen diameter ratio, liver stiffness, spleen stiffness and an association between liver stiffness and platelet count, referred to as the Baveno VI criteria. The Baveno VI criteria has recently been recommended by different medical associations for variceal screening. This is a critical review on the non-invasive methods for variceal screening, in which the performances of the different methods are presented and the limitations of the existing evidence is discussed. Despite reasonable performances of some of these methods, especially platelet count/spleen diameter ratio and the association between liver stiffness and platelet count, we understand that the available evidence still has relevant limitations and that physicians should decide on screening cirrhotic patients for esophageal varices with endoscopy or non-invasive methods on a case-by-case basis.

Abstract
Platelets (PLTs) are involved in tumor growth, metabolism and vascular activation. PLT-based models have been reported to have significant value on the recurrence of malignant hepatic tumors. The present study aimed to investigate the effect of PLT count and 18 PLT-based models on the prognosis of patients with malignant hepatic tumors. The clinical data from 189 patients with malignant hepatic tumors were retrospectively analyzed and used to calculate the scores of the 18 PLT-based models. Receiver operating characteristic curve was used to determine the suitable cut-off values of mortality and recurrence in patients with malignant hepatic tumors. The overall survival and cumulative recurrence rates of patients were calculated using Kaplan-Meier survival curves and the difference was analyzed using log-rank test. Multivariate analysis was performed to determine the independent risk factors of recurrence-free survival and overall survival. In the present study, 11 models were considered as predictors of mortality (P<0.05) and six models were considered as predictors of recurrence (P<0.05). The results from multivariate analysis demonstrated that vascular cancer embolus, uric acid >231 µmol/l, hemoglobin >144 g/l and the Lok index model >0.695 were considered as independent risk factors of mortality (P<0.05). Furthermore, vascular cancer embolus, PLT to lymphocyte ratio (PLR) >175 and fibrosis-4 (FIB-4) >4.82 were independent factors of recurrence (P<0.05). In addition, the results from this study indicated that the Lok-index could be considered as a predictor of the overall survival rate. In conclusion, the FIB-4 and PLR model may be valuable for predicting the recurrence-free rate of patients with malignant hepatic tumors.

Abstract
PURPOSE To investigate the prognostic value of 17 platelet-based prognostic scores in patients with malignant hepatic tumors after TACE therapy. METHODS In total, 92 patients were divided into death group and survival group according to long-term follow-up results. The AUC was calculated to determine the optimal cut-off values for predicting prognosis. To determine better prognostic models, platelet-based models were analyzed separately after being showed as binary according to cut-off values. Cumulative survival rates of malignant hepatic tumors were calculated using Kaplan-Meier curves and differences were analyzed by the log-rank test. Univariate and multivariate analyses were performed to identify platelet-based prognostic scores associated with overall survival. RESULTS Univariate analysis showed that APGA, APRI, FIB-4, FibroQ, GUCI, King's score, Lok index, PAPAS, cirrhosis, number of tumors, vascular cancer embolus, AFP, ALP and APTT were significantly related to prognosis. A multivariate analysis showed that the APGA, number of tumors, ALP and APTT were independently associated with overall survival. CONCLUSION This study showed that the APGA, a platelet-based prognostic score, was an independent marker of prognosis in patients with malignant hepatic tumors after TACE and was superior to the other platelet-based prognostic scores in terms of prognostic ability.

Abstract
Background The production of peripheral platelet is mainly regulated by thrombopoietin, which is a glycoprotein hormone predominantly synthesized in the liver. Previously, many studies have reported that there was an inverse correlation between the degree of chronic viral hepatitis and the peripheral platelet count. However, the effect of nonalcoholic fatty liver disease (NAFLD) on the peripheral platelet counts remains unclear. Methods With 1303 participants from “The prevention of MS and multi-metabolic disorders in Jiangsu province of China (PMMJS)” cohort study, we investigated the associations between NAFLD and the risk of platelet counts reduction in Chinese adults. The paired-samples T test was used to explore the platelet counts changes between baseline and follow-up. Multivariate logistic regression was used to examine the association between presence of NAFLD and the risk of platelet reduction by calculating the odds ratios (ORs) and 95% confidence interval (CI). Results After five years of follow-up, platelet counts were markedly reduced from 220.6 ± 42.22 (109/L) at baseline to 208.41 ± 40.70 (109/L) at follow-up in NAFLD group (P < 0.0001). However, platelet counts were slightly lowered from 213.2 ± 43.26(109/L) at baseline to 211.8 ± 41.65 (109/L) at follow-up in non-NAFLD people (P = 0.2349). Meanwhile, there was a significant association between NAFLD and the risks of platelet count reduction, even after adjustment for confounding variables (OR: 1.68, 95% CI: 1.06–2.67). Additionally, among the participants with BMI ≤ 23 kg/m2 and SUA ≤ 344.3 μmol/L, the NAFLD participants have an increased risk of platelet count reduction compared to the persons in non-NAFLD group. Conclusions Our present results suggested that NAFLD individuals have an increased risk of platelet counts reduction.

Abstract
BACKGROUND AND AIM Non-invasive markers are essential to assess the progression of chronic liver diseases to fibrosis/ cirrhosis and the effectiveness of therapeutic strategies. The aim of this study was to evaluate the ability of non-invasive markers to identify significant fibrosis, severe fibrosis, and cirrhosis in patients with autoimmune hepatitis (AIH). METHODS Seventy-six patients with AIH were enrolled in the study and analyzed for the following parameters of liver fibrosis: Fibrosis 4 score (FIB-4), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR), AST to platelet count ratio (APRI), and platelet count to spleen diameter (PC/SD) ratio. All patients underwent liver biopsy. The diagnostic accuracy of tests was evaluated by the area under the receiver operating characteristic curve (AUROC). RESULTS Among the 76 AIH patients, 55 (72.3%) had significant fibrosis (≥ F2), 37 (48.7%) had severe fibrosis (≥ F3), and 29 (38.2%) had cirrhosis (F4). PC/SD ratio (AUROC = 0.840) was superior to AAR (AUROC = 0.756), FIB-4 (AUROC = 0.702), and APRI (AUROC = 0.626) in discriminating between mild and significant fibrosis (≥ F2). The AUROCs of PC/SD ratio, FIB-4, AAR, and APRI were 0.884, 0.742, 0.731, and 0.707, respectively, for severe fibrosis (≥ F3); 0.968, 0.795, 0.744, and 0.723, respectively, for cirrhosis (F4). PC/SD ratio correctly identified 85.1% of patients with severe fibrosis, and 89.6% of patients with cirrhosis. CONCLUSIONS PC/SD ratio proved to be a simple non-invasive tool to correctly identify AIH patients with severe fibrosis and cirrhosis, thereby reducing the need for a liver biopsy in these patients.

Abstract
Oxaliplatin-based regimens are standard treatments for the patients with colorectal cancer (CRC) and advanced gastric cancer (AGC). However, owing to hepatic sinusoidal obstruction syndrome (SOS), the use of oxaliplatin sometimes results in splenomegaly. The aim of the present study was to evaluate the correlation between chemotherapy-associated changes of noninvasive liver fibrosis indices and volumetric changes of the spleen.From February 2004 to April 2014, patients with CRC or AGC receiving oxaliplatin-based chemotherapy were studied. The possibility of SOS development was evaluated before and after the oxaliplatin exposure with splenic volume index (SVI). Four different noninvasive liver fibrosis indices were used for risk analysis, namely age-platelet index (API), AST-to-platelet ratio index (APRI), platelet-to-spleen ratio (PSR), and fibrosis-4 score (FIB-4).A total of 275 patients were eligible for evaluation: 200 patients had CRC and 75 patients had AGC. Using the cutoff of SVI increase ≥ 0.3, 113 patients (41.1%) were positive for splenomegaly. The changes of indices significantly correlated with SVI increase. Adjusted odds ratios for those indices were as follows: API = 1.16 (95% confidential interval [CI], 1.01-1.32; P = .03); APRI = 2.45 (95% CI, 1.30-4.63; P = .01); PSR = 0.69 (95% CI, 0.59-0.80; P < .01); and FIB-4 = 1.37 (95% CI, 1.16-1.63; P < .01). Optimal cutoff values with statistical significance were calculated and suggested.The changes of noninvasive liver fibrosis indices showed a good correlation with the increase in the spleen volume during oxaliplatin-based chemotherapy. Validation of these indices for monitoring of oxaliplatin-induced hepatic SOS is warranted.

Abstract
BACKGROUND Liver biopsy is the reference standard for diagnosing the extent of fibrosis in chronic liver disease; however, it is invasive, with the potential for serious complications. Alternatives to biopsy include non-invasive liver tests (NILTs); however, the cost-effectiveness of these needs to be established. OBJECTIVE To assess the diagnostic accuracy and cost-effectiveness of NILTs in patients with chronic liver disease. DATA SOURCES We searched various databases from 1998 to April 2012, recent conference proceedings and reference lists. METHODS We included studies that assessed the diagnostic accuracy of NILTs using liver biopsy as the reference standard. Diagnostic studies were assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Meta-analysis was conducted using the bivariate random-effects model with correlation between sensitivity and specificity (whenever possible). Decision models were used to evaluate the cost-effectiveness of the NILTs. Expected costs were estimated using a NHS perspective and health outcomes were measured as quality-adjusted life-years (QALYs). Markov models were developed to estimate long-term costs and QALYs following testing, and antiviral treatment where indicated, for chronic hepatitis B (HBV) and chronic hepatitis C (HCV). NILTs were compared with each other, sequential testing strategies, biopsy and strategies including no testing. For alcoholic liver disease (ALD), we assessed the cost-effectiveness of NILTs in the context of potentially increasing abstinence from alcohol. Owing to a lack of data and treatments specifically for fibrosis in patients with non-alcoholic fatty liver disease (NAFLD), the analysis was limited to an incremental cost per correct diagnosis. An analysis of NILTs to identify patients with cirrhosis for increased monitoring was also conducted. RESULTS Given a cost-effectiveness threshold of £20,000 per QALY, treating everyone with HCV without prior testing was cost-effective with an incremental cost-effectiveness ratio (ICER) of £9204. This was robust in most sensitivity analyses but sensitive to the extent of treatment benefit for patients with mild fibrosis. For HBV [hepatitis B e antigen (HBeAg)-negative)] this strategy had an ICER of £28,137, which was cost-effective only if the upper bound of the standard UK cost-effectiveness threshold range (£30,000) is acceptable. For HBeAg-positive disease, two NILTs applied sequentially (hyaluronic acid and magnetic resonance elastography) were cost-effective at a £20,000 threshold (ICER: £19,612); however, the results were highly uncertain, with several test strategies having similar expected outcomes and costs. For patients with ALD, liver biopsy was the cost-effective strategy, with an ICER of £822. LIMITATIONS A substantial number of tests had only one study from which diagnostic accuracy was derived; therefore, there is a high risk of bias. Most NILTs did not have validated cut-offs for diagnosis of specific fibrosis stages. The findings of the ALD model were dependent on assuptions about abstinence rates assumptions and the modelling approach for NAFLD was hindered by the lack of evidence on clinically effective treatments. CONCLUSIONS Treating everyone without NILTs is cost-effective for patients with HCV, but only for HBeAg-negative if the higher cost-effectiveness threshold is appropriate. For HBeAg-positive, two NILTs applied sequentially were cost-effective but highly uncertain. Further evidence for treatment effectiveness is required for ALD and NAFLD.

Abstract
BACKGROUND & AIMS We elaborate a non-invasive score system for liver fibrosis (NISF), exploring its diagnostic performance and comparing its accuracy to FibroScan in patients with chronic viral hepatitis (CH) and non-alcoholic fatty liver disease (NAFLD). METHODS Clinical, biochemical, elastographic and ultrasound parameters derived from patients with CH (n = 83) or NAFLD (n = 58), undergoing liver biopsy for fibrosis assessment, were prospectively collected as potential predictors of fibrosis. Each parameter was evaluated for its correlation with the liver biopsy (Gold Standard). Candidate predictors with good interobserver agreement and correlation with histological stages were combined into two algorithms (NISF) to predict fibrosis in chronic viral hepatitis and NAFLD. RESULTS The CH-NISF included six parameters: bluntness of liver edges, irregularity of left lobe surface, diameter of segment 4, liver stiffness measurement, platelet count and ALT values. The ability of the model to discriminate F3-F4 vs F0-F1 stages and F2 vs F0-F1 was high (AUROC of 0.95 and 0.83 respectively) and better than FibroScan alone, especially in intermediate stages (F2 vs F0-F1), AUROC 0.83 vs 0.57 (P = 0.003). The resulting algorithm is available as mathematical formula, nomogram or free online link. [http://health.mafservizi.it/NISF_Calculator/liver.htm] The NAFLD-NISF included liver stiffness, platelet count and AST levels, had good ability to discriminate F0-F1 vs F2-F3-F4 stages (AUROC 0.86), however, not significantly higher than FibroScan. CONCLUSIONS CH-NISF can be proposed as preliminary and easily available staging tool, superior to FibroScan alone in predicting histological fibrosis, especially in intermediate stages. Further validations are needed to improve NISF accuracy in NAFLD.

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
Liver fibrosis is the final common pathway for almost all causes of chronic liver injury. Liver fibrosis is now known to be a dynamic process having significant potential for resolution. Therefore, fibrosis prediction is an essential part of the assessment and management of patients with chronic liver disease. As such, there is strong demand for reliable liver biomarkers that provide insight into disease etiology, diagnosis, therapy, and prognosis in lieu of more invasive approaches such as liver biopsy. Current diagnostic strategies range from use of serum biomarkers to more advanced imaging techniques including transient elastography and magnetic resonance imaging. In addition to these modalities, there are other approaches including the use of novel, but yet to be validated, biomarkers. In this chapter, we discuss the biomarkers of liver fibrosis including the use of invasive and noninvasive biomarkers and disease-specific biomarkers in various chronic liver diseases.

Abstract
BACKGROUND & AIMS Variceal bleeding is a dramatic and common complication of cirrhosis, and, therefore, endoscopy is recommended for the screening of EV (esophageal varices) in every cirrhotic. This study evaluates the capacity of APRI (aspartate aminotransferase-to-platelet ratio index) in non-invasively predicting EV. MATERIAL AND METHODS This cross-sectional study evaluated cirrhotics for their APRI value and the presence of EV, with a cutoff point of 1, 3; platelet count, spleen diameter, PC/SD (platelet count/ spleen diameter ratio), aspartate aminotransferase/alanine aminotransferase ratio, Child-Pugh score and MELD (model for end-stage liver disease) score were also studied. RESULTS The study included 164 cirrhotics, 59.7% male, with a mean age of 56.7 years. APRI demonstrated a sensitivity of 64.7% (95% confidence interval-95%CI = 0.56-0.73), specificity of 72.7% (95%CI = 0.59-0.86), positive predictive value of 86.5% (95%CI = 0.79-0.94), negative predictive value of 43.2% (95%CI = 0.32-0.55). In the univariate analysis, platelet count, spleen diameter, Child and MELD scores, PC/SD and APRI were related to EV (p < 0.05). In the logistic regression, only platelet count and Child score were associated to EV (p < 0.05). CONCLUSION APRI is not an independent factor for the prediction of EV. Its sensitivity, specificity and predictive values are insufficient for the index to be used for the screening of EV in cirrhotics.

Abstract
BACKGROUNDS & AIMS Intrahepatic recurrence of hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) occurs as a result of direct dissemination or de novo oncogenesis. Hepatocellular carcinogenesis is related to the progression of cirrhosis, and noninvasive fibrosis scoring systems reflect the severity of hepatic fibrosis. Hence, the aim of this study was to elucidate the correlation between noninvasive fibrosis indices and intrahepatic distant recurrence (IDR) of HCC after RFA. METHODS Patients with hepatitis B virus (HBV)-related, solitary HCC undergoing RFA were prospectively enrolled. Noninvasive serum fibrosis indices were calculated at the time of RFA. IDR was defined as recurrent HCC beyond >2 cm from the ablation margin of RFA. Predictors of IDR and overall survival were analysed by a Cox regression model. RESULTS Two hundred forty-six patients received RFA as initial treatment, and the median follow-up duration was 19.7 months (IQR, 11.9-29.8). Among these cases, 133 (45.9%) showed IDR after RFA. In multivariable analysis, serum alpha-fetoprotein (AFP) (HR, 1.000; 95% CI, 1.000-1.001; P = 0.001) and age-platelet index (API) (1.19; 1.01-1.39; P = 0.033) were independent predictors of IDR. In particular, patients with API ≤7 showed a significantly higher recurrence-free survival rate than patients with API >7 (P = 0.004). With regard to overall survival, male sex (4.69; 1.52-14.52; P = 0.007), serum bilirubin (2.78; 1.31-5.90; P = 0.008) and AFP (1.000; 1.000-1.001; P = 0.006) were significantly correlated with shortened survival. CONCLUSION High levels of AFP and API predict IDR of HBV-related HCC after RFA. Therefore, noninvasive fibrosis indices could play an important role in predicting IDR of HCC following percutaneous ablation.

Abstract
AIM: To explore the correlation between serum-ascites albumin gradient (SAAG) and the degree of esophageal varices in patients with liver cirrhosis.
METHODS: Cirrhotic patients with ascites were collected and divided into three groups according to the degree of esophageal varices: mild group, moderate group and severe group. One-way ANOVA, correlation analysis and receiver operating characteristic (ROC) curve were used for statistical analysis.
RESULTS: A total of 43 cirrhotic patients were included in our study. One-way ANOVA indicated a significant difference in SAAG among the three groups (F = 26.317, P < 0.001). Spearman correlation analysis suggested a positive correlation between SAAG and esophageal varices (r = 0.759, P < 0. 001). ROC curve analysis indicated that the area under the ROC curve was 0.926, and the best cut-off value for diagnosis of moderate and severe esophageal varices was 20.5 g/L, with a sensitivity of 87.1% and a specificity of 83.3%.
CONCLUSION: SAAG is correlated well with the degree of esophageal varices in cirrhotic patients, and this parameter has appreciable value in diagnosis of moderate and severe esophageal varices.

Abstract
We retrospectively studied 89 patients with chronic hepatitis C virus (HCV) infection, including 50 chronic hepatitis (CH) cases, 18 liver cirrhosis (LC) cases, and 21 LC with hepatocellular carcinoma (LC + HCC) cases, with regard to various factors related with thrombocytopenia. The platelet count decreased with the stage advancement of liver diseases. Multiple regression analysis revealed that splenomegaly and von Willebrand factor (vWF) were explanatory variables that correlated with thrombocytopenia. Splenomegaly appears to be the most responsible factor, although there are a considerable number of thrombocytopenic cases without splenomegaly, suggesting other factors may also be responsible. The vWF level is inversely correlated with the platelet count. Soluble thrombomodulin, a marker of endothelial dysfunction, increases with the advancement of liver fibrosis. It is positively correlated with vWF and inversely with the platelet count. Our present results imply that vascular endothelial dysfunction is also involved in thrombocytopenia during chronic HCV infection.

Abstract
CONTEXT Upper gastrointestinal bleeding associated to esophageal varices is the most dramatic complication of cirrhosis. It is recommended screening every cirrhotic for esophageal varices with endoscopy. OBJECTIVES To evaluate the capacity of the platelet count/spleen diameter ratio in non-invasively predicting esophageal varices in a population of cirrhotics originated in an independent center from the one in which it was developed. METHODS The study included patients from the ambulatory care clinic of cirrhosis of a Brazilian hospital and studied platelet count, spleen diameter and presence of esophageal varices, as well as Child and MELD scores. It used a cutoff value of 909 for the platelet count/spleen diameter ratio, as previously published. A sample of 139 patients was needed to grant results a 95% confidence level. RESULTS The study included 164 cirrhotics, 56.7% male, with a mean age of 56.6 ± 11.6 years. In the univariate analysis, platelet count, spleen diameter, presence of ascites, Child and MELD scores and the platelet count/spleen diameter ratio were related to esophageal varices (P<0.05). The platelet count/spleen diameter ratio had sensitivity of 77.5% (95% CI = 0.700-0.850), specificity of 45.5% (95% CI = 0.307-0.602), positive predictive value of 79.5% (95% CI = 0.722-0.868), negative predictive value of 42.6% (95% CI = 0.284-0.567) and accuracy of 68.9% (95% CI = 0.618-0.760). In the multivariate analysis, platelet count was the only variable which related to esophageal varices (P<0.05). CONCLUSION Platelet count/ spleen diameter ratio is not adequate to predict esophageal varices in cirrhotics.

Abstract
UNLABELLED The aspartate aminotransferase-to-platelet ratio index (APRI), a tool with limited expense and widespread availability, is a promising noninvasive alternative to liver biopsy for detecting hepatic fibrosis. The objective of this study was to update the 2007 meta-analysis to systematically assess the accuracy of APRI in predicting significant fibrosis, severe fibrosis, and cirrhosis stage in hepatitis C virus (HCV) monoinfected and HCV / human immunodeficiency virus (HIV) coinfected individuals. Studies comparing APRI versus biopsy in HCV patients were identified via a thorough literature search. Areas under summary receiver operating characteristic curves (AUROC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to examine the APRI accuracy for the diagnosis of significant fibrosis, severe fibrosis, and cirrhosis. Heterogeneity was explored using meta-regression. Twenty-one additional studies were eligible for the update and, in total, 40 studies were included in this review (n = 8,739). The summary AUROC of the APRI for the diagnosis of significant fibrosis, severe fibrosis, and cirrhosis were 0.77, 0.80, and 0.83, respectively. For significant fibrosis, an APRI threshold of 0.7 was 77% sensitive and 72% specific. For severe fibrosis, a threshold of 1.0 was 61% sensitive and 64% specific. For cirrhosis, a threshold of 1.0 was 76% sensitive and 72% specific. Moreover, we found that the APRI was less accurate for the identification of significant fibrosis, severe fibrosis, and cirrhosis in HIV/HCV coinfected patients. CONCLUSION Our large meta-analysis suggests that APRI can identify hepatitis C-related fibrosis with a moderate degree of accuracy. Application of this index may decrease the need for staging liver biopsy specimens among chronic hepatitis C patients.

Abstract
Background Chronic HCV is one of the major causes of morbidity and mortality in the present day world. The assessment of disease progression not only provides useful information for diagnosis and therapeutic supervision judgment but also for monitoring disease. Different invasive and non invasive methods are applied to diagnose the disease from initial to end stage (mild fibrosis to cirrhosis). Although, liver biopsy is still considered as gold standard to identify liver histological stages, an assessment of the disease development based on non-invasive clinical findings is also emerging and this may replace the need of biopsy in near future. This review gives brief insight on non-invasive methods currently available for predicting liver fibrosis in HCV with their current pros and cons to make easier for a clinician to choose better marker to assess liver fibrosis in HCV infected patients. Methods More than 200 studies regarding invasive and noninvasive markers available for HCV liver disease diagnosis were thoroughly reviewed. We examined year wise results of these markers based on their sensitivity, specificity, PPV, NPV and AUROCs. Results We found that in all non-invasive serum markers for HCV, FibroTest, Forn's Index, Fibrometer and HepaScore have high five-year predictive value but with low AUROCs (0.60~0.85) and are not comparable to liver biopsy (AUROC = 0.97). Even though from its beginning, Fibroscan is proved to be best with high AUROCs (> 0.90) in all studies, no single noninvasive marker is able to differentiate all fibrosis stages from end stage cirrhosis. Meanwhile, specific genetic markers may not only discriminate fibrotic and cirrhotic liver but also differentiate individual fibrosis stages. Conclusions There is a need of marker which accurately determines the stage based on simplest routine laboratory test. Genetic marker in combination of imaging technique may be the better non invasive diagnostic method in future.

Abstract
INTRODUCTION Fibrogenesis is a typical reaction of the liver to injury. In the case of overstimulation of fibrogenesis clinically significant fibrosis and, eventually, cirrhosis occur. Treatment of liver cirrhosis is limited, therefore it is important to screen and monitor patients at risk of cirrhosis. Noninvasive parameters are ideal for this purpose due to their risk profile and repeatability. METHODS Systematic review of literature. RESULTS Among large number of proposed biomarkers, there is a distinct difference between two groups or classes. Class I biomarkers are associated with the process of fibrogenesis, their presence in the serum is the result of the increased turnover of extracellular matrix. Class II biomarkers and their combinations are mostly markers of liver function or structural damage. We have identified 27 Class I and 13 Class II biomarkers that have been proposed in the literature. We have evaluated in detail those which reached limited clinical application. CONCLUSION General clinical acceptance of these biomarkers is low because of various drawbacks. Simple and readily available biomarkers have low accuracy in predicting liver fibrosis and more advanced markers have low cost-benefit ratio. Therefore liver biopsy remains the "gold standard" for diagnosis of fibrosis. However potential noninvasive alternatives exist and their implementation could be valuable.

Abstract
BACKGROUND Accurate determination of the presence and degree of liver fibrosis is essential for prognosis and for planning treatment of patients with chronic hepatitis C virus (HCV). Non-invasive methods of assessing fibrosis have been developed to reduce the need for biopsy. AIM To perform a review of these non-invasive measures and their ability to replace biopsy for assessing hepatic fibrosis in patients with chronic HCV. METHODS A systematic review of PUBMED and EMBASE was performed through 2008 using the following search terms: HCV, liver, elastography, hepatitis, Fibroscan, SPECT, noninvasive liver fibrosis, ultrasonography, Doppler, MRI, Fibrotest, Fibrosure, Actitest, APRI, Forns and breath tests, alone or in combination. RESULTS We identified 151 studies: 87 using biochemical, 57 imaging and seven breath tests either alone or in combination. CONCLUSIONS Great strides are being made in the development of accurate non-invasive methods for determination of fibrosis. Although no single non-invasive test or model developed to date can match that information obtained from actual histology (i.e. inflammation, fibrosis, steatosis), combinations of two modalities of non-invasive methods can reliably differentiate between minimal and significant fibrosis, and thereby avoid liver biopsy in a significant percentage of patients.

Abstract
Fibrosis is a frequent, life-threatening complication of most chronic liver diseases. Despite major achievements in the understanding of its pathogenesis, the translation of this knowledge into clinical practice is still limited. In particular, non-invasive and reliable (serum-) biomarkers indicating the activity of fibrogenesis are scarce. Class I biomarkers are defined as serum components having a direct relation to the mechanism of fibrogenesis, either as secreted matrix-related components of activated hepatic stellate cells and fibroblasts or as mediators of extracellular matrix (ECM) synthesis or turnover. They reflect primarily the activity of the fibrogenic process. Many of them, however, proved to be disappointing with regard to sensitivity and speci-ficity. Up to now hyaluronan turned out to be the relative best type I serum marker. Class II biomarkers comprise in general rather simple standard laboratory tests, which are grouped into panels. They fulfil most criteria for detection and staging of fibrosis and to a lesser extent grading of fibrogenic activity. More than 20 scores are currently available, among which Fibrotest™ is the most popular one. However, the diagnostic use of many of these scores is still limited and standardization of the assays is only partially realized. Combining of panel markers in sequential algorithms might increase their diagnostic validity. The translation of genetic pre-disposition biomarkers into clinical practice has not yet started, but some polymorphisms indicate a link to progression and outcome of fibrogenesis. Parallel to serum markers non-invasive physical techniques, for example, transient elastography, are developed, which can be combined with serum tests and profiling of serum proteins and glycans.

Abstract
UNLABELLED The development of noninvasive markers of liver fibrosis is a clinical and research priority. The aspartate aminotransferase-to-platelet ratio index (APRI) is a promising tool with limited expense and widespread availability. Our objective was to systematically review the performance of the APRI in hepatitis C virus (HCV)-infected patients. Random effects meta-analyses and areas under summary receiver operating characteristic curves (AUC) were examined to characterize APRI accuracy for significant fibrosis (stages 2-4) and cirrhosis. In 22 studies (n = 4,266), the summary AUCs of the APRI for significant fibrosis and cirrhosis were 0.76 [95% confidence interval (CI), 0.74-0.79] and 0.82 (95%CI, 0.79-0.86), respectively. For significant fibrosis, an APRI threshold of 0.5 was 81% sensitive and 50% specific. At a 40% prevalence of significant fibrosis, this threshold had a negative predictive value (NPV) of 80%, but could reduce the necessity of liver biopsy by only 35%. For cirrhosis, a threshold of 1.0 was 76% sensitive and 71% specific. At a 15% cirrhosis prevalence, the NPV of this threshold was 91%. Higher APRI thresholds had suboptimal positive predictive values except in settings with a high prevalence of cirrhosis. APRI accuracy was not affected by the prevalence of advanced fibrosis, or study and biopsy quality. However, the accuracy for cirrhosis was greater in studies including human immunodeficiency virus (HIV)/HCV-co-infected patients. CONCLUSION The major strength of the APRI is the exclusion of significant HCV-related fibrosis. Future studies of novel markers should demonstrate improved accuracy and cost-effectiveness compared with this economical and widely available index.

Abstract
BACKGROUND Fibrosis is the excessive deposition and histological redistribution of extracellular matrix (ECM) in the tissue as consequence of chronic liver damage. It leads to progressive liver insufficiency, portal hypertension and ultimately to cirrhosis and primary liver cell carcinoma. There is a strong demand for reliable, organ- and disease-specific, non-invasive biomarkers of fibrosis and fibrogenesis to replace or to complement the invasive method of needle biopsy, which is afflicted with a high degree of sampling error. METHODS A systematic literature search was performed using electronic databases and reference lists of relevant publications to ascertain studies with non-invasive biomarkers of liver fibrosis. RESULTS Two classes of serum biomarkers can be differentiated: Class I markers are those, which reflect ECM turnover (fibrogenesis and fibrolysis) and/or fibrogenic cell changes, mainly of hepatic stellate cells, which are the dominant profibrogenic cell type in liver. They are mostly cost intensive, single laboratory tests and derive from the translation of fibrogenic mechanisms into clinical application. Examples are procollagen peptides, hyaluronan, and laminin. Class II biomarkers are based on algorithmic evaluation of commonly observed functional alterations of the liver that do not necessarily reflect ECM metabolism and/or fibrogenic cell changes. About 20 numerical scores or indices are reported for parameters, which are mostly routine laboratory tests and frequently multiparametric (panels). Among them fibrotest, hepascore, ELF-score have reached limited clinical application. CONCLUSIONS Up to now the impact of both classes of biomarkers for diagnosis and monitoring of fibrosis, fibrogenesis, and fibrolysis is limited. They cannot replace needle biopsy but some of them might be complementary in follow-up studies. Innovative methods like proteomics and glycomics to establish fibrosis-specific serum protein and glycosylation patterns, respectively, might have a high potential for diagnosis and monitoring of fibrogenesis.
