Chen H, Dai S, Fang Y, Chen L, Jiang K, Wei Q, Ding K. Hepatic Steatosis Predicts Higher Incidence of Recurrence in Colorectal Cancer Liver Metastasis Patients. Front Oncol 2021; 11:631943. [PMID: 33767997 PMCID: PMC7986714 DOI: 10.3389/fonc.2021.631943] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Accepted: 02/08/2021] [Indexed: 12/24/2022] Open
Abstract
Purpose: Colorectal liver metastasis (CRLM) is the major cause of death due to colorectal cancer. Although great efforts have been made in treatment of CRLM, about 60–70% of patients will develop hepatic recurrence. Hepatic steatosis was reported to provide fertile soil for metastasis. However, whether hepatic steatosis predicts higher incidence of CRLM recurrence is not clear. Therefore, we aimed to determine the role of hepatic steatosis in CRLM recurrence in the present study. Methods: Consecutive CRLM patients undergoing curative treatment were retrospectively enrolled and CT liver-spleen attenuation ratio was used to detect the presence of hepatic steatosis. In patients with hepatic steatosis, we also detected the presence of fibrosis. Besides, a systematic literature search was performed to do meta-analysis to further analyze the association between hepatic steatosis and CRLM recurrence. Results: A total of 195 eligible patients were included in our center. Patients with hepatic steatosis had a significantly worse overall (P = 0.0049) and hepatic recurrence-free survival (RFS) (P = 0.0012). Univariate and multivariate analysis confirmed its essential role in prediction of RFS. Besides, hepatic fibrosis is associated with worse overall RFS (P = 0.039) and hepatic RFS (P = 0.048). In meta-analysis, we included other four studies, with a total of 1,370 patients in the case group, and 3,735 patients in the control group. The odds ratio was 1.98 (95% CI: 1.25–3.14, P = 0.004), indicating that patients with steatosis had a significantly higher incidence of CRLM recurrence. Conclusion: In summary, patients with hepatic steatosis had a significantly worse overall and hepatic RFS and it's associated with higher incidence of CRLM recurrence.

Abstract
AIM OF THE STUDY Hepatitis C virus (HCV) can cause a chronic liver infection which could then develop into fibrosis, cirrhosis, and hepatocellular carcinoma. Today the diagnosis of liver fibrosis also includes the use of biomarkers. The purpose of our study was to determine the ability of the fibrosis index based on four factors (FIB-4) and aspartate aminotransferase-to-platelet ratio (APRI) to predict the severity of liver fibrosis or cirrhosis. MATERIAL AND METHODS Medical records of 106 patients with HCV-related liver fibrosis were analyzed. All patients underwent clinical examination, blood tests (complete blood count, total bilirubin, etc.) and transient elastography. FIB-4 and APRI were calculated for each patient. RESULTS Twenty-six patients (24.52%) had F4 fibrosis, 80 patients (75.48%) had non-F4 fibrosis (F0-F3). There was a statistically significant difference (p < 0.05) between non-F4 fibrosis patients and F4 fibrosis patients in many parameters, including APRI (F4 fibrosis patients had higher values: 2.06 ±3.22 compared to 0.68 ±0.76 of the non-F4 group; p = 0.044) and FIB-4 (F4 fibrosis patients had higher values: 4.84 ±4.14 compared to 2.29 ±2.90 of the non-F4 group; p = 0.006). Receiver operating characteristic (ROC) curve analysis for APRI and FIB-4 revealed that the area under the curve (AUC) of FIB-4 was 0.855 (CI: 0.813-0.936), while the APRI score had an AUC of 0.767 (CI: 0.79-0.932). CONCLUSIONS In this study, patients with severe fibrosis or cirrhosis were found to have a higher FIB-4 value than APRI in the context of chronic hepatitis C.

Abstract
PURPOSE OF REVIEW Aging-related comorbidities, including liver disease, represent the main drivers of morbidity and mortality in people with HIV (PWH). Nonalcoholic fatty liver disease (NAFLD) seems a frequent comorbidity in aging PWH nowadays. NAFLD results from a fat deposition into the liver parenchyma that may evolve to nonalcoholic steatohepatitis (NASH), a state of hepatocellular inflammation and injury in response to the accumulated fat leading to liver fibrosis and cirrhosis. We here review the current status of knowledge regarding this emerging comorbidity in PWH. RECENT FINDINGS Recent studies suggest that PWH are at higher risk for both NASH and NASH-related liver fibrosis. Several hypothesized pathogenic mechanisms may account for this finding, including increased metabolic comorbidities, hepatotoxic effect of lifelong antiretroviral therapy, and chronic HIV infection. In clinical practice, non-invasive diagnostic tests, such as serum biomarkers and elastography, may help identify patients with NASH-related fibrosis, thus improving risk stratification, and enhancing clinical management decisions, including early initiation of interventions such as lifestyle changes and potential pharmacologic interventions. Clinicians should remain informed of the frequency, significance, and diagnostic and management approach to NASH in PWH.

Abstract
Transient elastography (TE) is a non-invasive technology that demonstrates promise in assessing liver steatosis and fibrosis without the risks of traditional percutaneous liver biopsy. Many studies have examined its reliability in respect to liver biopsy, but fewer have examined using TE in obese and bariatric surgery patients. With evidence showing that bariatric surgery can lead to improvement of liver steatosis and fibrosis, TE has the potential to provide a simple avenue of hepatic assessment in patients before and after procedures. This review article investigates what is known about the reliability of TE and its implementation in obese and bariatric surgery patients.

Abstract
BACKGROUND/AIMS The hepatitis C virus (HCV) infection is important cause of chronic hepatitis. Liver biopsy is considered the gold standard for assessment of fibrosis but this procedure is an invasive procedure. We aimed to evaluate the diagnostic efficiency of non-invasive serum biomarkers, separately and in combinations, on liver fibrosis in treatment-naive chronic hepatitis C (CHC) patients. MATERIALS AND METHODS Two hundred and sixteen treatment-naive CHC patients were enrolled from 32 locations across Turkey in this open-labelled, non-interventional prospective observational study. FibroTest®, aspartate aminotransferase-to-platelet ratio index(APRI), aspartate aminotransferase and alanine aminotransferase ratio (AAR), fibrosis index based on four factors (FIB-4), Age-platelet(AP) index and Forns index were measured and compared with Metavir scores got from liver biopsies. RESULTS Data from 182 patients with baseline liver biopsy were suitable for analysis. One hundred and twenty patients (65.9%) had F0-F1 fibrosis and 62 patients (34.1%) had F2-F4 fibrosis. APRI 0.732 area under the curve(AUC) indicated advanced fibrosis with 69% sensitivity and 77% specificity. FIB-4 0.732 AUC and FibroTest 0.715 AUC indicated advanced fibrosis with 69% and 78.4% sensitivity, and 75% and 71.4% specificity, respectively. The combined use of tests also led to an increase in AUC and specificity. Combinations of FibroTest with APRI and/or FIB-4, and FIB-4 with APRI were optimal for the evaluation of liver fibrosis. CONCLUSION Fibrotest, FIB-4, APRI, AP index and Forns index exhibit good diagnostic performance for determining liver fibrosis in CHC patients, and the use of at least two tests together will increase their diagnostic value still further.

Abstract
Primary biliary cholangitis (PBC) is a chronic disease that is increasingly being recognized in recent years. In this study, we sought to identify noninvasive markers of the severity of cirrhosis in patients with PBC based on routinely investigated laboratory parameters.Ninety-four patients with histologically-confirmed PBC based on liver biopsy performed between January 2013 and December 2017 at the First Hospital of Jilin University were divided into 2 groups: early-stage cirrhosis (fibrosis stage F1 and F2; n = 74) and advanced-stage cirrhosis (fibrosis stage F3 and F4; n = 20).Patients with advanced-stage had significantly higher red blood cell distribution width (RDW) (15.2 vs 13.7; P = .003) and significantly lower platelet (163.35 vs 202.73; P = .032) and lymphocyte counts (1.47 vs 1.79; P = .018) as compared with patients with early-stage cirrhosis. Advanced-stage cirrhosis was associated with significantly higher RDW to platelet ratio (RPR), RDW to lymphocyte ratio (RLR), aspartate aminotransferase to platelet ratio index (APRI), and fibrosis index based on the 4 factors (FIB-4) as compared with early-stage cirrhosis. RLR showed the highest area under receiver operating characteristic curve (AUROC) (0.744). The sensitivity and specificity of RLR were 65% and 78.3%, respectively. RLR had higher AUROC than the other 3 noninvasive markers.The noninvasive markers RPR, RLR, APRI, and FIB-4 showed good diagnostic accuracy for advanced-stage cirrhosis. These markers are easily acquired by routine laboratory tests and are reproducible predictors of the severity of PBC. RLR is a novel marker that may serve as a valuable supplement to APRI and FIB-4 for predicting the severity of cirrhosis.

Abstract
BACKGROUND The aim of this study is to investigate the association between hepatic activity index (HAI) and fibrosis score (FS) with inflammation biomarkers in non-uremic and uremic hepatitis C positive patients. METHODS Fifty chronic hepatitis C (cHepC) positive patients, having a liver biopsy were included in this study. Liver biopsies were scored according to modified ISHAC scoring system. 25 healthy controls of similar age and gender were also enrolled as control group. Serum YKL-40, neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (PLR), CRP and Immunoglobulin (IgG, A and M) levels were used to determine inflammation. AST to Platelet Ratio Index (APRI) score was also evaluated. According to biopsy findings patients were divided into 2 groups: low (0-2) and severe (3-6) FS. RESULTS Patients with cHepC had increased inflammation compared to the healthy controls. End-stage renal disease (ESRD) patients had higher levels of inflammation markers (NLR, IgG, CRP and YKL-40) and lower HCV RNA levels, HAI and FS compared to non-uremic patients. When patients were grouped into 2 according to FS as mild and severe, IgG (p < 0.001), YKL-40 (p = 0.02) levels and APRI score (p = 0.002) were significantly higher compared to mild FS (p = 0.002). YKL-40 levels (t value: 3.48; p = 0.001) and APRI score (t value: 4.57, p < 0.001) were found as independent associated with FS in non-uremic patients. However, in adjusted models, only APRI score (t value: 3.98, p = 0.002) was an independent associated with FS in ESRD patients. CONCLUSION In non-uremic cHepC patients, YKL-40 levels and APRI score may be valuable markers of FS. In ESRD patients, there is not sufficient data for prediction of HAI and FS. In these patients, APRI score may provide better information.

Abstract
Background Serum interleukin 6 (IL‐6), chemokine ligand 2 (CCL2), C‐reactive protein (CRP), and the ratio of aspartate transaminase to alanine transaminase (AST:ALT) have been correlated with fibrosis and necroinflammatory activity in humans with various hepatopathies. Hypothesis/Objectives To determine whether increases in serum IL‐6, CCL2, CRP, or AST:ALT were associated with moderate to severe fibrosis or necroinflammatory activity in dogs with various hepatopathies. Animals Forty‐four client‐owned dogs with clinical evidence of liver disease and 10 healthy purpose‐bred dogs, all undergoing liver biopsies by laparoscopy or laparotomy. Methods Measurement of serum IL‐6, CCL2, CRP, AST, and ALT before scheduled liver biopsy and evaluation of liver histopathology using the METAVIR scoring system used in human medicine, blinded to clinical presentation. Results Median serum IL‐6 was approximately twice as high in dogs with high fibrosis scores (15.5 pg/mL; range, 1.4 to 235 pg/mL) compared to dogs with low fibrosis scores (7.6 pg/mL; range, 1.4 to 148.1 pg/mL), with marginal significance (P = .05). Median serum CCL2 was significantly higher in dogs with active necroinflammation (444 pg/mL; range, 144 to 896 pg/mL) compared to dogs without detectable necroinflammation (326 pg/mL; range, 59 to 1692 pg/mL; P = .008), but with considerable overlap between groups. Neither serum CRP nor AST:ALT ratios were significantly different based on fibrosis or necroinflammatory scores. Conclusions and Clinical Importance Because of substantial variability among dogs, single measurements of IL‐6 and CCL2 have limited diagnostic utility for identifying fibrosis or necroinflammation, respectively, in dogs with various chronic liver diseases. The value of these biomarkers should be explored further in monitoring response to treatment in individual dogs with chronic hepatopathies.

Abstract
Hepatic fibrosis is a chronic disorder caused by viral infection and/or metabolic, genetic and cholestatic disorders. A noninvasive procedure that enables the detection of liver fibrosis based on redox status would be useful for disease identification and monitoring, and the development of treatments. However, an appropriate technique has not been reported. This study describes a novel method for assessing the redox status of the liver using in vivo dynamic nuclear polarization-magnetic resonance imaging (DNP-MRI) with the nitroxyl radical carbamoyl-PROXYL as a molecular imaging probe, which was tested in dimethylnitrosamine-treated mice as a model of liver fibrosis. Based on the pharmacokinetics of carbamoyl-PROXYL in control livers, reduction rate mapping was performed in fibrotic livers. Reduction rate maps demonstrated a clear difference between the redox status of control and fibrotic livers according to the expression of antioxidants. These findings indicate that in vivo DNP-MRI with a nitroxyl radical probe enables noninvasive detection of changes in liver redox status.

Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) are at high risk for non-alcoholic fatty liver disease (NAFLD). Longitudinal data on incident NAFLD are lacking. We employed non-invasive methods to study incidence and predictors of NAFLD. METHODS This was a retrospective study of IBD patients without known liver disease followed at IBD clinic of McGill University. NAFLD was defined as Hepatic Steatosis Index (HSI) ≥36 and absence of alcohol intake. Advanced liver fibrosis was diagnosed by FIB-4 ≥2.67. Active IBD was defined as partial Mayo score ≥3 for ulcerative colitis, Harvey Bradshaw Index ≥ 5 or flare during follow-up. Kaplan-Meier and Cox regression analyses were used to investigate incidence and predictors of NAFLD development. RESULTS Three hundred twenty-one consecutive patients (median age 33.7 yr, 47% males) were observed for a median of 3.2 years (interquartile range 1.5-6). Over 1181.2 persons-year (PY), 108 (33.6%) patients developed NAFLD, accounting for an incidence rate of 9.1/100 PY (95% confidence interval [CI], 7.4-10.9). 7 (2.2%) patients developed advanced liver fibrosis, accounting for an incidence rate of 0.5/100 PY (95% CI, 0.2-1.1). Development of NAFLD was predicted by disease activity (adjusted hazard ratio [aHR] = 1.58; 95% CI, 1.08-2.33, P = 0.02), disease duration (aHR = 1.12; 95% CI, 1.03-1.23, P = 0.01), and prior surgery for IBD (aHR = 1.34; 95% CI, 1.04-1.74, P = 0.02). CONCLUSIONS NAFLD is a frequent comorbidity in patients with IBD. These patients can also develop advanced liver fibrosis. Disease activity, duration of IBD and prior surgery are predictors of NAFLD development. This should represent one more incentive to achieve and maintain early clinical remission. Further prospective studies are of interest.

Abstract
Currently, a major clinical challenge in the management of the increasing number of hepatitis C virus (HCV) infected patients is determining the best means for evaluating liver impairment. Prognosis and treatment of chronic hepatitis C (CHC) are partly dependent on the assessment of histological activity, namely cell necrosis and inflammation, and the degree of liver fibrosis. These parameters can be provided by liver biopsy; however, in addition to the risks related to an invasive procedure, liver biopsy has been associated with sampling error mostly due to suboptimal biopsy size. To avoid these pitfalls, several markers have been proposed as non-invasive alternatives for the diagnosis of liver damage. Distinct approaches among the currently available non-invasive methods are (1) the physical ones based on imaging techniques; and (2) the biological ones based on serum biomarkers. In this review, we discuss these approaches with special focus on currently available non-invasive serum markers. We will discuss: (1) class I serum biomarkers individually and as combined panels, particularly those that mirror the metabolism of liver extracellular matrix turnover and/or fibrogenic cell changes; (2) class II biomarkers that are indirect serum markers and are based on the evaluation of common functional alterations in the liver; and (3) biomarkers of liver cell death, since hepatocyte apoptosis plays a significant role in the pathogenesis of HCV infection. We highlight in this review the evidence behind the use of these markers and assess the diagnostic accuracy as well as advantages, limitations, and application in clinical practice of each test for predicting liver damage in CHC.

Abstract
BACKGROUND & AIMS Diagnosis of preclinical compensated cirrhosis (occult cirrhosis, OC) is challenging due to lack of clinical findings. We evaluated prevalence and outcomes of OC by transient elastography (TE, Fibroscan(®)). METHODS Eight hundred and seventy-one patients with compensated chronic liver disease (CLD) and TE examination were divided into: (i) OC (TE ≥ 13 kPa and no sign of cirrhosis, including absence of thrombocytopenia and signs of advanced liver disease on ultrasound or gastroscopy); (ii) clinically evident cirrhosis (TE ≥ 13 kPa with signs of cirrhosis); (iii) non-cirrhotic CLD (TE < 13 kPa). Outcomes included hepatocellular carcinoma (HCC), esophageal varices and ascites. Late diagnosis of outcomes was defined as HCC stage ≥intermediate by BCLC or variceal bleeding. RESULTS Occult cirrhosis represented 12% of the cohort and 37% of cirrhotic patients. Independent predictors of OC were age [odds ratio (OR) 1.15; 95% confidence interval (CI), 1.04-1.26], HIV co-infection (OR 3.53; 95% CI, 1.85-6.76) and APRI (OR 2.63; 95 CI, 1.87-3.71). During a median follow-up of 24 (interquartile range 20-37) months, OC received less surveillance than clinically evident cirrhosis, with fewer ultrasounds (2.7 ± 1.5 vs 3.6 ± 2; P < 0.001) and gastroscopies (2 ± 0.8 vs 2.6 ± 1.4; P < 0.001). Incidence of outcomes was 3.5/100 per person-years (PY) (95% CI, 0.1-6.9) in OC, 0 in non-cirrhotic CLD and 9.8/100 PY (95% CI, 0.3-19.3) in clinically evident cirrhosis (P < 0.001). Late diagnosis occurred more in OC than clinically evident cirrhosis (60 vs 15%, P = 0.01). CONCLUSIONS Occult cirrhosis is a frequent and under-monitored clinical entity associated with short-term risk of outcomes. TE may help early diagnosis, prompt initiation of surveillance and specific therapy for an otherwise unrecognized condition.

Liver and spleen stiffness and their ratio assessed by real-time two dimensional-shear wave elastography in patients with liver fibrosis and cirrhosis due to chronic viral hepatitis. Eur Radiol 2015; 25:3214-21.

Abstract
OBJECTIVES To investigate the performance of real-time 2D shear wave elastography (RT 2D-SWE) for non-invasive staging of liver disease in patients with chronic viral hepatitis (CVH). MATERIALS AND METHODS Naive CVH patients underwent liver (LS) and spleen stiffness (SS) measurements by an intercostal approach. Patients with ALT >3× upper limit of normal, cholestasis as revealed by dilated intrahepatic biliary tree, and liver congestion were excluded. Results were expressed in kPa and compared to histological stage (Ishak) of liver fibrosis (LF). Patients with decompensated liver cirrhosis (LC) were diagnosed using standard clinical, ultrasound, and endoscopic criteria. RESULTS Of 123 patients, LS was successfully measured in 79.7% and SS in 53.7%. LS accurately differentiated between liver disease stages, with cut-off values of 8.1 (AUC 0.991) for F ≥ 3, 10.8 kPa (AUC 0.954) for F ≥ 5, and 27 kPa (AUC 0.961) for decompensated LC. SS was significantly different between non-cirrhotic stages (F0-4) and LC (cut-off 24 kPa; AUC 0.821). While both LS and SS increased with liver disease progression, the difference between them decreased, as reflected by the stiffness ratio index. CONCLUSIONS RT 2D-SWE can accurately differentiate between the stages of LF, and can distinguish LF from LC and compensated from decompensated LC. KEY POINTS • RT 2D-SWE is an accurate method for assessment of liver fibrosis. • RT 2D-SWE is applicable in 80% of patients with chronic viral hepatitis. • RT 2D-SWE accurately differentiates compensated from decompensated liver cirrhosis. • Both liver and spleen stiffness increase with progression of liver fibrosis. • In cirrhosis, the difference between liver and spleen stiffness decreases.

Abstract
The plasma profile of sphingolipids in hepatic fibrosis patients with chronic hepatitis C (CHC) is rarely considered at present. The association between plasma sphingolipids and severe fibrosis in CHC remains an obscure area of research. The aim of the present study was to assess the plasma profile of sphingolipids and to examine the association between plasma sphingolipids and severe fibrosis in CHC, in order to identify potential novel markers of severe fibrosis in CHC. A cohort of 120 treatment-naïve patients with CHC were included in the present study. Liver biopsies were performed and routine serological indicators were measured. Plasma sphingolipids were detected using high performance liquid chromatography tandem mass spectrometry. A total of 44 plasma sphingolipids were detected. Plasma hexosylceramide (HexCer; d18:1/12:0), HexCer (d18:1/16:0) and HexCer (d18:1/22:0) were shown to be significantly different in patients with CHC between those with and without severe fibrosis (Metavir F ≥ 3; P < 0.05). HexCer (d18:1/12:0) was observed to be closely associated with severe fibrosis in CHC [odds ratio (OR)=1.03] following adjustment for confounding variables in a multivariate analysis. HexCer (d18:1/12:0) had diagnostic value for severe fibrosis in CHC [area under the curve (AUC)=0.69]. In patients with CHC who had developed significant fibrosis (Metavir F ≥ 2), HexCer (d18:1/12:0) remained closely associated with severe fibrosis (OR=1.08) in this subgroup. In addition, HexCer (d18:1/12:0) had sufficient diagnostic ability (AUC=0.73) to distinguish severe fibrosis in patients with CHC with significant fibrosis. In conclusion, the present study indicated that plasma HexCer (d18:1/12:0) exhibits a close correlation with severe hepatic fibrosis in CHC, particularly in patients who have significant fibrosis. Additionally, HexCer (d18:1/12:0) may be a potential marker of severe hepatic fibrosis in CHC.

Abstract
Chronic infection with hepatitis C virus (HCV) is a leading cause of liver-related morbidity and mortality worldwide and predisposes to liver fibrosis and end-stage liver complications. Liver fibrosis is the excessive accumulation of extracellular matrix proteins, including collagen, and is considered as a wound healing response to chronic liver injury. Its staging is critical for the management and prognosis of chronic hepatitis C (CHC) patients, whose number is expected to rise over the next decades, posing a major health care challenge. This review provides a brief update on HCV epidemiology, summarizes basic mechanistic concepts of HCV-dependent liver fibrogenesis, and discusses methods for assessment of liver fibrosis that are routinely used in clinical practice. Liver biopsy was until recently considered as the gold standard to diagnose and stage liver fibrosis. However, its invasiveness and drawbacks led to the development of non-invasive methods, which include serum biomarkers, transient elastography and combination algorithms. Clinical studies with CHC patients demonstrated that non-invasive methods are in most cases accurate for diagnosis and for monitoring liver disease complications. Moreover, they have a high prognostic value and are cost-effective. Non-invasive methods for assessment of liver fibrosis are gradually being incorporated into new guidelines and are becoming standard of care, which significantly reduces the need for liver biopsy.

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
OBJECTIVE To determine practices among physicians in Canada for the assessment of liver fibrosis in patients with chronic liver diseases. METHODS Hepatologists, gastroenterologists, infectious diseases specialists, members of the Canadian Gastroenterology Association and⁄or the Canadian HIV Trials Network who manage patients with liver diseases were invited to participate in a web-based, national survey. RESULTS Of the 237 physicians invited, 104 (43.9%) completed the survey. Routine assessment of liver fibrosis was requested by the surveyed physicians mostly for chronic hepatitis C (76.5%), followed by autoimmune⁄cholestatic liver disease (59.6%) and chronic hepatitis B (52.9%). Liver biopsy was the main diagnostic tool for 46.2% of the respondents, Fibroscan (Echosens, France) for 39.4% and Fibrotest (LabCorp, USA) for 7.7%. Etiology-specific differences were observed: noninvasive methods were mostly used for hepatitis C (63% versus 37% liver biopsy) and hepatitis B (62.9% versus 37.1% liver biopsy). For 42.7% of respondents, the use of noninvasive methods reduced the need for liver biopsy by >50%. Physicians' characteristics associated with higher use of noninvasive methods were older age and being based at a university hospital or in private practice versus community hospital. Physicians' main concerns regarding noninvasive fibrosis assessment methods were access⁄availability (42.3%), lack of guidelines for clinical use (26.9%) and cost⁄lack of reimbursement (14.4%). CONCLUSIONS Physicians who manage patients with chronic liver diseases in Canada require routine assessment of liver fibrosis stage. Although biopsy remains the primary diagnostic tool for almost one-half of respondents, noninvasive methods, particularly Fibroscan, have significantly reduced the need for liver biopsy in Canada. Limitations in access to and availability of the noninvasive methods represent a significant barrier. Finally, there is a need for clinical guidelines and a better reimbursement policy to implement noninvasive tools to assess liver fibrosis.

Abstract
The primary aim of antiviral therapy for chronic hepatitis C (CHC) is the prevention of progressive disease. A response to interferon (IFN) treatment is associated with an improvement in all-cause mortality and liver-related mortality from hepatitis C. Unless contraindicated, patients with CHC are thus potential candidates for treatment. Improved response rates are observed in patients with HCV genotype 1 infection treated with first-generation protease inhibitors. However, treatment with current first-generation protease inhibitors and IFN is complex and can result in appreciable adverse effects. The advent of potent, pan-genotypic all-oral direct-acting antiviral (DAA) regimens necessitates a critical examination of the immediate application of PEG-IFN, ribavirin and DAA regimens in patients with CHC. Current guidelines and position statements do not make clear recommendations, and are behind the emerging data. Some aspects of the conundrums facing physicians and patients are summarized in this Review. Cirrhosis presents an immediate threat of disease, and ideally treatment should be targeted at those patients who have advancing or advanced disease; unfortunately, a disparity exists, as response rates are reduced in patients with cirrhosis and the risks of adverse events are increased. On balance, patients with mild disease could consider deferring treatment.

AST/ALT ratio is not an index of liver fibrosis in chronic hepatitis C when aminotransferase activities are determinate according to the international recommendations. Clin Res Hepatol Gastroenterol 2013; 37:467-72.

Abstract
OBJECTIVE The aspartate aminotransferase activity (AST)/alanine aminotransferase activity (ALT) ratio is used as liver fibrosis index whereas the reported data are conflicting. In chronic hepatitis C (CHC), reported diagnostic accuracies range from none to good for significant fibrosis and to excellent for cirrhosis. Assuming that AST/ALT increases are mainly due to vitamin B6 defects since pyridoxal phosphate (PLP), active form of B6, acts as coenzyme in transamination reactions, we evaluated the diagnostic accuracy of the AST/ALT ratio using standardized methods for AST and ALT activities, with PLP addition as recommended, in a prospective multicenter cohort of CHC patients. METHODS ALT and AST activities were measured using the recommended IFCC methods with addition of pyridoxal 5'-phosphate. We evaluated the AST/ALT ratio for the diagnosis of liver fibrosis or cirrhosis in a cohort of CHC patients included in a multicenter prospective study. A liver biopsy was performed in each patient and reviewed by two independent pathologists in order to determine the fibrosis stage according to Metavir classification which was the reference standard. RESULTS AST/ALT ratio significantly increased with histological stage of liver fibrosis and there was a significant correlation between Metavir fibrosis stage and AST/ALT ratio (r=0.129, P<0.0035). The ROC curve analyses showed that the AST/ALT ratio does not discriminate significant fibrosis (F≥2) (AUROC=0.531) and had only very poor diagnostic accuracies for severe fibrosis (F≥3) (AUROC=0.584) or cirrhosis (F4) (AUROC=0.626). CONCLUSION AST/ALT ratio is not a good and discriminative index of liver fibrosis in CHC when aminotransferase activities are determinate according to the international recommendations.

Abstract
AIMS Accurate liver fibrosis staging is crucial for the management of chronic hepatitis C (CHC). The invasiveness and cost burden of liver biopsy have driven the search for new noninvasive biomarkers of fibrosis. Based on the link between serum angiopoietin-1 and 2 levels and CHC progression, we aimed to determine the value of these angiogenic factors as noninvasive biomarkers of liver fibrosis. METHODS Serum levels of angiopoietin-1 and -2 were measured by ELISA in 108 CHC patients who underwent pretreatment liver biopsy. The correlation between angiopoietins and clinical and demographic variables with liver fibrosis was analyzed by univariate regression. Significant factors were then subjected to multivariate analysis, from which we constructed a novel noninvasive liver fibrosis index (AngioScore), whose performance was validated in an independent series of 71 CHC patients. The accuracy of this model was compared with other documented fibrosis algorithms by De Long test. RESULTS Angiopoietins correlated significantly with hepatic fibrosis; however, only angiopoietin-2 was retained in the final model, which also included age, platelets, AST, INR, and GGT. The model was validated and behaved considerably better than other fibrosis indices in discriminating all, significant, moderate and severe liver fibrosis (0.886, 0.920, 0.923). Using clinically relevant cutoffs, we classified CHC patients by discarding significant fibrosis and diagnosing moderate and severe fibrosis with greater accuracy, sensitivity, and specificity. CONCLUSIONS Our novel noninvasive liver fibrosis model, based on serum angiopoietin-2 levels, outperforms other indices and should help substantially in managing CHC and monitoring long-term follow-up prognosis.

Abstract
The development of ultrasound-based elasticity imaging methods has been the focus of intense research activity since the mid-1990s. In characterizing the mechanical properties of soft tissues, these techniques image an entirely new subset of tissue properties that cannot be derived with conventional ultrasound techniques. Clinically, tissue elasticity is known to be associated with pathological condition and with the ability to image these features in vivo; elasticity imaging methods may prove to be invaluable tools for the diagnosis and/or monitoring of disease. This review focuses on ultrasound-based elasticity imaging methods that generate an acoustic radiation force to induce tissue displacements. These methods can be performed noninvasively during routine exams to provide either qualitative or quantitative metrics of tissue elasticity. A brief overview of soft tissue mechanics relevant to elasticity imaging is provided, including a derivation of acoustic radiation force, and an overview of the various acoustic radiation force elasticity imaging methods.
