Abstract
Transforming growth factor-β (TGF-β) is a key driver for liver fibrogenesis. TGF-β must be activated in order to function. Plasma kallikrein (PLK) is a TGF-β activator that cleaves the latency-associated protein (LAP) between arginine58 and lysine59 residues and releases active TGF-β from the latent TGF-β-LAP complex. Thus, the generation of two LAP degradation products, ending at arginine58 (R58/LAP-DPs) and beginning from lysine59 (L59/LAP-DPs), reflects PLK-dependent TGF-β activation. However, the significance and details of TGF-β activation in patients with chronic liver disease (CLD) remain uncertain. We herein examined the PLK-dependent TGF-β activation in patients by detecting R58 and L59/LAP-DPs. A total of 234 patients with CLD were included in this study. Liver biopsy specimens were used for immunostaining to detect R58/LAP-DPs, while plasma samples were subjected to an enzyme-linked immunosorbent assay to measure the L59/LAP-DP concentration. R58/LAP-DP was robustly expressed in and around the sinusoidal cells before the development of the fibrous regions. The R58/LAP-DP expression at fibrosis stage 1 was higher than at any other stages, and the relationship between the plasma L59/LAP-DP level and the stage of fibrosis also showed a similar trend. The abundance of plasma L59/LAP-DP showed no correlation with the levels of direct serum biomarkers of liver fibrosis; however, its changes during interferon-based therapy for chronic hepatitis C were significantly associated with virological responses. Our results suggest that PLK-dependent TGF-β activation occurs in the early stages of fibrosis and that its unique surrogate markers, R58 and L59/LAP-DPs, are useful for monitoring the clinical course of CLD.

Abstract
Aims Collagen‐derived peptides such as collagen I C‐terminal telopeptide (CITP) and procollagen III N‐terminal propeptide (PIIINP) have been conventionally used as markers of cardiac fibrosis. Collagen IV 7S domain (P4NP 7S) has been recently reported to be correlated with haemodynamics in patients with acute heart failure. We investigated whether these markers reflect cardiac remodelling and myocardial collagen expression. Methods and results In 80 patients with dilated cardiomyopathy, relationships of CITP, PIIINP, and P4NP 7S to clinical and echocardiographic variables were analysed. CITP and PIIINP were inversely correlated with estimated glomerular filtration rate (r = −0.41, P < 0.001 and r = −0.32, P = 0.004, respectively); P4NP 7S was positively correlated with B‐type natriuretic peptide (r = 0.32, P = 0.003) and γ‐glutamyltransferase (r = 0.38, P < 0.001). These correlations were significant even after adjustment by potential confounders, whereas all three collagen markers were not independently correlated with ejection fraction nor with left ventricular (LV) diastolic diameter. In 33 patients undergoing endomyocardial biopsy, myocardial collagen I and III mRNA expressions were correlated with LV end‐diastolic volume index (r = 0.42, P = 0.02 and r = 0.54, P = 0.002, respectively), whereas myocardial collagen IV mRNA expression was not correlated with LV end‐diastolic volume index nor with ejection fraction. Each collagen‐derived peptide was not significantly correlated with the myocardial expression of their corresponding collagen mRNA. Conclusions Our study shows that CITP, PIIINP, and P4NP 7S do not reflect myocardial collagen mRNA expression but presumably reflect extra‐cardiac organ injury in heart failure.

Abstract
Tc-99m-galactosyl human serum albumin (GSA) scintigraphy is used to assess the hepatic functional reserve, and allows for visual assessment of the residual hepatocyte distribution on single-photon emission computed tomography/computed tomography (SPECT/CT) images. The association between heterogeneous liver uptake of Tc-99m-GSA and liver fibrosis remains to be studied in detail. We analyzed this association.Fifty-one patients with chronic hepatobiliary disease undergoing a Tc-99m-GSA scintigraphy were included in this study. The receptor (LHL15) and blood clearance (HH15) indexes (the uptake ratios of the liver and heart) were obtained from dynamic planar images. The liver uptake count maximum-to-mean ratio (LUC Max/Mean) was calculated from single-photon emission computed tomography/computed tomography (SPECT/CT) images as an indicator of the Tc-99m-GSA liver uptake heterogeneity. We assessed the relationship between these quantified values and liver fibrosis.There were 30 Child-Pugh classification grade A patients, 16 grade B patients, and 5 grade C patients. Among the 30 patients whose liver histopathology was evaluable, those with advanced liver fibrosis (F2-4) had a lower LHL15 than those with mild liver fibrosis (F0-1) (median, 0.90 vs. 0.92, P = .04), and a higher LUC Max/Mean (median, 1.80 vs. 1.70, P = .02). The multivariate analysis identified platelets (P = .04) and the LUC Max/Mean (P = .04) as contributing factors of advanced liver fibrosis.These findings suggest that Tc-99m-GSA SPECT/CT can be used not only to assess the hepatic functional reserve, but also to evaluate a degree of liver fibrosis.

Abstract
To explore the relation between connective tissue growth factor (CTGF) in serum and the severity of liver fibrosis, and to determine the clinical value of CTGF in the assessment of liver fibrosis, serum CTGF was tested utilizing enzyme-linked immunosorbent assay (ELISA). The correlation between serum CTGF concentration and fibrosis stage was assessed. The diagnostic performance of CTGF was assessed by comparing the area under the receiver operating characteristic (ROC) curves (AUC) with a panel of fibrosis markers. The correlation coefficient was 0.689 (P < 0.001) between the levels of serum CTGF and fibrosis stages and the AUC of CTGF was 0.841 (95% confidence interval [CI] 0.762-0.920) in distinguishing mild fibrosis from significant fibrosis. The present data revealed that serum CTGF was significantly correlated with the stage of liver fibrosis, suggested that serum CTGF was an indicator for the stage of liver fibrosis, and shown evidence that serum CTGF could be used as a valuable marker for assessing liver fibrosis.

Abstract
OBJECTIVE The objectives of this study were to investigate the use of non-invasive biochemical markers to evaluate the severity of liver fibrosis in patients with non-alcoholic steatohepatitis (NASH). METHODS This was a cross-sectional study of patients with histopathologically confirmed NASH between January 2005 and December 2006. The patients' characteristics were recorded and the body mass index was calculated for each patient. All patients underwent ultrasound-guided liver biopsy and a fibrosis assessment was performed using the Brunt criteria. The non-invasive laboratory markers measured were insulin resistance, tumor necrosis factor (TNF-alpha), type IV collagen and hyaluronic acid (HA). RESULTS Thirty patients were recruited, of whom 18 (60%) were men. Their mean age was 45 +/- 13.9 (18-71) years. About 83% of patients had fibrosis stage 1-2. In bivariate analysis, age, TNF-alpha and type IV collagen concentrations showed a weak but significant correlation with the fibrosis stage. When the patients were grouped into mild fibrosis (stages 1-2) and advanced fibrosis (stages 3-4), the mean concentrations of HA and type IV collagen were significantly higher in those with advanced fibrosis than those with mild fibrosis (180.8 +/- 49.63 vs 543.6 +/- 360.45 ng/mL; for HA; P = 0.026 and 125.3 +/- 32.11 vs 288.0 +/- 171.22 ng/mL for type IV collagen; P = 0.010). CONCLUSION Our study showed that the degree of liver fibrosis was significantly correlated with age, TNF-alpha and type IV collagen concentrations. The level of HA and type IV collagen could differentiate between mild (F1-2) and advanced fibrosis (F3-4).

Abstract
Several beneficial effects of splenectomy on the liver integrity have been recently reported by both experimental and clinical studies. However, the effects of splenectomy on hepatic functional reserve and structural damage in patients with chronic hepatitis C (CHC) were not studied by objective evidence. The aim of this study was to assess the effect of splenectomy on hepatic functional reserve and structural damage in patients with CHC by non-invasive serum markers. The study involved 22 patients with histopathological diagnosis of CHC undergoing splenectomy for treatment of associated hypersplenism. The hepatic functional reserve and structural damage markers were assessed before and after splenectomy surgery on the 2nd and 60th postoperative days by aspartate aminotransferase to alanine aminotransferase (AST/ALT ratio), AST to platelet ratio index (APRI) and serum levels of gamma-glutamyl transferase (GGT), hyaluronic acid (HA), type IV collagen (CIV) and tissue inhibitor of metalloproteinase-1 (TIMP-1). After splenectomy, the levels of serum HA showed a significant decrease in relation to the preoperative values both in PO-1 (mean pre-splenectomy: 272+/-88.6 versus 185+/-77.4 ng/ml; P=0.01) and PO-2 (169+/-58.1 ng/ml; 0.017). The levels of type IV collagen showed a significant decrease in relation to the preoperative values both in PO-1 (mean pre-splenectomy: 208+/-134 versus 125+/-100 ng/ml; P=0.01) and PO-2 (121+/-74.7 ng/ml; P=0.02). Serum levels of TIMP-1 also showed a significant decrease in relation to the preoperative values both in PO-1 (mean pre-splenectomy: 764+/-571 versus 261+/-195 ng/ml; P=0.006) and PO-2 (149+/-110.1 ng/ml; P=0.004). There was no significant difference between PO-1 and PO-2 mean values for each of those serum markers. This study found that splenectomy induced a reduction of biochemical markers of liver functional reserve and fibrosis in patients with chronic hepatitis C which reflect a change in the processes involved in of liver fibrosis. However, it cannot be concluded whether this reflects a change in the rate of its progression or a prevention of further fibrosis.

Abstract
BACKGROUND The changes in nonalcoholic fatty liver disease range over a wide spectrum, extending from simple steatosis to nonalcoholic steatohepatitis (NASH). We investigated the clinical usefulness of the type IV collagen 7s domain and hyaluronic acid for predicting the severity of fibrosis before progression to the cirrhotic stage in NASH patients. METHODS The type IV collagen 7s domain and hyaluronic acid were measured in 72 patients with histologically verified NASH. RESULTS In a univariate analysis, marked elevation of hyaluronic acid and the type IV collagen 7s domain was observed in the NASH patients with advanced fibrosis compared with those with mild fibrosis (P = 0.0028, P = 0.0006, respectively). For detection of NASH with advanced fibrosis, the area under the receiver-operating characteristic curves for type IV collagen 7s domain and hyaluronic acid were 0.767 and 0.754, respectively. However, multiple regression analysis revealed that the type IV collagen 7s domain, but not hyaluronic acid, was significantly elevated in patients with advanced fibrosis even after adjustment for age, sex, platelet count, prothrombin time, aspartate aminotransferase/alanine aminotransferase ratio, body mass index, and presence of underlying type 2 diabetes mellitus, all of which have previously been reported as useful predictors of advanced fibrosis in patients with NASH (P = 0.0127, P = 0.2804, respectively). CONCLUSIONS This is the first report to demonstrate a consistent and profound elevation of the type IV collagen 7s domain in NASH patients with advanced fibrosis (before progression to the stage of cirrhosis) compared with those with mild fibrosis.

Abstract
Hepatic fibrosis in patients with non-alcoholic fatty liver disease is associated with progression of the disease. In the present study, we analyzed the discriminative ability of serum laminin, type IV collagen and hyaluronan levels to predict the presence of fibrosis in these patients. In this preliminary report, we studied 30 overweight patients divided into two groups according to the absence (group I, N = 19) or presence (group II, N = 11) of fibrosis in a liver biopsy. Triglycerides, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltranspeptidade, hyaluronan (noncompetitive fluoroassay), type IV collagen, and laminin (ELISA) were determined. Group II presented significantly higher mean laminin, hyaluronan, type IV collagen, and aspartate aminotransferase values, which were due to the correlation between these parameters and the stage of fibrosis in the biopsy (Spearman's correlation coefficient, rS = 0.65, 0.62, 0.53, and 0.49, respectively). Analysis of the ROC curve showed that laminin values >282 ng/ml were those with the best diagnostic performance, with 87% accuracy. Association of laminin with type IV collagen showed improvement in the positive predictive value (100%), but with reduction in diagnostic sensitivity (64%). When compared with the criteria of Ratziu et al. for the diagnosis of septal fibrosis, laminin values presented a better diagnostic accuracy (83 vs 70%). Determination of extracellular matrix components in serum, especially of laminin, may identify patients with non-alcoholic fatty liver disease and fibrosis and these components may be used as indicators for liver biopsy in these patients.

Abstract
AIM: Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD), and progresses to the end stage of liver disease. Biochemical markers of liver fibrosis are strongly associated with the degree of histological liver fibrosis in patients with chronic liver disease. However, data are few on the usefulness of markers in NAFLD patients. The aim of this study was to identify better noninvasive predictors of hepatic fibrosis, with special focus on markers of liver fibrosis, type VI collagen 7S domain and hyaluronic acid.
METHODS: One hundred and twelve patients with histologically proven NAFLD were studied.
RESULTS: The histological stage of NAFLD correlated with several clinical and biochemical variables, the extent of hepatic fibrosis and the markers of liver fibrosis were relatively strong associated. The best cutoff values to detect NASH were assessed by using receiver operating characteristic analysis: type VI collagen 7S domain ≥5.0 ng/mL, hyaluronic acid ≥43 ng/mL. Both markers had a high positive predictive value: type VI collagen 7S domain, 86% and hyaluronic acid, 92%. Diagnostic accuracies of these markers were evaluated to detect severe fibrosis. Both markers showed high negative predictive values: type VI collagen 7S domain (≥5.0 ng/mL), 84% and hyaluronic acid (≥50 ng/mL), 78%, and were significantly and independently associated with the presence of NASH or severe fibrosis by logistic regression analysis.
CONCLUSION: Both markers of liver fibrosis are useful in discriminating NASH from fatty liver alone or patients with severe fibrosis from patients with non-severe fibrosis.

The diagnosis of liver fibrosis has traditionally relied on liver biopsy. However, recent studies have suggested that there can be up to a 33 % error in the diagnosis of cirrhosis. In this article, we review the current status of liver biopsy as a gold standard for the diagnosis of liver fibrosis and discuss the radiological and serum tests that have been proposed as potential adjuncts or alternatives to biopsies. Indirect markers of liver fibrosis which reflect alterations in liver function and or inflammation are discussed as well as more direct markers of liver fibrosis. The limitations of utilization of these markers for both cross-sectional diagnosis of fibrosis and monitoring disease progression or regression are discussed.

Abstract
BACKGROUND It has been reported that chronic infection with hepatitis C virus is associated with excess iron deposits in the liver of subjects who are neither alcoholics nor recipients of blood transfusions. However, little is known about the relationship between hepatic iron concentration (HIC) and the serum levels of hepatic fibrogenesis markers, which were caused by interferon therapy for chronic hepatitis C. Therefore, changes in the serum amino-terminal propeptide of type III procollagen (P-III-P) and the 7S domain of type IV collagen (7S-IV) in 16 patients treated with alpha-interferon (IFN-alpha) were studied, and their HIC and histological assessment evaluated. Hepatic iron concentrations were measured by using liver biopsy specimens obtained before and 6 months after the cessation of treatment. METHODS AND RESULTS Eight subjects (50%) who had normal alanine transaminase levels at 6 months after therapy showed significantly lowered HIC, and attenuated hepatic iron staining with decreased serum levels of P-III-P and 7S-IV compared to the remaining subjects. The HIC was significantly correlated with the serum levels of P-III-P and 7S-IV in all subjects. CONCLUSIONS These findings suggest that IFN-alpha treatment may decrease stimuli for fibrogenesis, at least in part, by reducing the hepatic iron deposition in patients with chronic hepatitis C.

Abstract
There is a clinical need for noninvasive measurement of liver fibrosis both to diagnose significant liver fibrosis and to monitor the effects of therapy on fibrogenesis and fibrolysis. Multiple clinical markers have been evaluated over the years, and as our understanding of the molecular process of liver scarring has advanced, newer markers have appeared. Serum markers include extracellular matrix proteins such as the N-terminal propeptide of collagen III, hyaluronan, YKL-40, laminin, metalloproteinases, and their inhibitors. Use of multiple markers has led to 90% sensitivity in diagnosing cirrhosis, but specificity is variable at about 60%. Automated systems to measure these markers are under development and are being evaluated for their ability to monitor fibrosis during and after therapy in multiple liver diseases, including hepatitis B and C. Although no individual fibrosis marker is clinically applicable today, we foresee a future in which monitoring fibrosis markers will replace sequential liver biopsy as a standard of care.
