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

J Vet Intern Med 2016; 30:973-82. [PMID: 27425382 PMCID: PMC5108467 DOI: 10.1111/jvim.14373] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2015] [Revised: 04/25/2016] [Accepted: 06/11/2016] [Indexed: 01/03/2023] Open
Abstract
Background N‐terminal type III procollagen propeptide (PIIINP) is a biomarker of soft tissue proliferation. Hypersomatotropism (HS) is associated with soft tissue proliferation. Hypothesis Serum PIIINP is increased in cats with HS and decreases with effective treatment, and may be an additional tool in the diagnosis and treatment of feline HS. Animals Cats with uncomplicated diabetes mellitus (DM; n = 30) and with HS‐induced DM (HSDM; n = 30). Pre‐ and posttreatment samples were available from 5 cats undergoing radiotherapy (RT) and 16 cats undergoing hypophysectomy (HPX). Methods Retrospective and prospective cross‐sectional study. Analytical performance of a serum PIIINP ELISA was assessed and validated for use in cats. PIIINP and insulin‐like growth factor 1 (IGF‐1) radioimmunoassays (RIA) were performed pre‐ and post‐treatment in cats with DM and HSDM. PIIINP and IGF‐1 were compared between cats treated by RT and HPX. Results Serum PIIINP concentrations were significantly higher (P < .001) in HSDM cats (median, 19.6 ng/mL; range, 1.7–27.9) compared to DM cats (median, 5.0 ng/mL; range, 2.1–10.4). A cut‐off of 10.5 ng/mL allowed differentiation between DM and HSDM cats with 87% sensitivity and 100% specificity (area under the curve [AUC], 0.91; 95% confidence interval [CI], 0.82‐1). After RT, PIIINP increased significantly (P = .043) with no significant change in IGF‐1 concentrations. After HPX, serum PIIINP (P = .034) and IGF‐1 concentrations (P < .001) decreased significantly. Conclusion and clinical importance PIIINP concentrations are increased in cats with untreated HSDM compared to those with DM, demonstrating the effect of excess GH on soft tissue. PIIINP concentrations decreased after HPX in most HSDM cats.

Abstract
Collagen type III alpha 1 (COL3A1) is one of the extracelluar matrix (ECM) proteins. The expression of COL3A1 is closely related to chronic liver diseases. In this study, we investigated whether single nucleotide polymorphisms (SNPs) of COL3A1 confer genetic susceptibility to patients with hepatitis B virus-infected liver diseases including chronic hepatitis B (CH), liver cirrhosis (CIR), and hepatocellular carcinoma (HCC). A total of 399 Korean (KOR) people, 111 patients with CH, 95 patients with CIR, 86 patients with HCC, and 107 spontaneously recovery, were genotyped for 16 SNPs of the COL3A1 gene. The 'A' allele of rs3106796 was highly associated with the CH [odds ratio (OR) = 1.62, P = 0.01], CIR (OR = 1.67, P = 0.01), and HCC (OR = 1.59, P = 0.03). There were six polymorphic SNPs that could be divided into two linkage disequilibrium (LD) blocks. The haplotype pattern of the KOR control seems to be similar to the patterns displayed in the Japanese, Chinese, and Caucasian populations sampled in the International HapMap project. Haplotype 3 (A-G-A) of the LD block 2 was significantly associated with CH (OR = 2.23, P = 0.02), CIR (OR = 2.24, P = 0.03), and HCC (OR = 2.27, P = 0.03). Moreover, diplotype analysis showed that they had increased relative risk for CH and CIR in the two diplotypes, dt3 (A-G-A/G-G-A; OR = 4.05, P = 0.01) and dt6 (A-A-A/A-G-A; OR = 7.42, P = 0.01 and OR = 5.84, P = 0.05) against dt1 (G-G-A/G-G-A), the most common diplotype in both KOR groups. In vitro reporter gene assays showed that the constructs containing the 'G' allele of rs3106796 appear to exert lower transcriptional activity of COL3A1 than the 'A' allele, depending on the promoter types.

Abstract
The mechanism underlying disease progression in hepatitis B virus (HBV) infection is unknown. Immunoglobulins stimulate the proliferative activity of rat hepatic stellate cells in vitro. A strong association was found between serum immunoglobulin levels and hepatic fibrosis in patients with hepatitis C virus infection. Our objective was to determine if the same index could also be used in patients with chronic HBV infection. The records of 100 patients with biochemical, serological, virological and histological evidence of chronic HBV infection were reviewed for background factors and serum globulin and immunoglobulin levels. Mean (+/-SD) patient age was 44.0 +/- 14.7 years; 80 (80%) were male. Of the factors found to be significant on univariate analysis, the only significant predictors of severe hepatic fibrosis (stage > or = 2) on multivariate analysis were serum globulin level [odds ratio (OR) 5.97, 95% confidence intervals (CI) 1.82-19.53, P = 0.0004], platelet count (OR 0.98, CI 0.97-0.99, P = 0.001), and immunoglobulin G (IgG) level (OR 1.003, CI 1.000-1.007, P < 0.042) but not IgA, alkaline phosphatase, albumin or international normalized ratio. For each increase of 0.33 mg/dL in serum globulin, there was a 0.5 point increase in the stage of hepatic fibrosis. There appears to be a strong association between levels of serum globulin and IgG and extent of hepatic fibrosis in patients with chronic HBV infection. They can serve as noninvasive markers of hepatic fibrosis and, if confirmed, have important implications for the management of patients with chronic HBV infection.

Abstract
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 AIMS Liver biopsy is the gold standard for assessing hepatitis B virus (HBV)-related histology. The aim was to determine the diagnostic utility of noninvasive serum markers in patients with chronic hepatitis B. METHODS The aminotransferases and indices including alpha(2)-macroglobulin, apolipoprotein A1, haptoglobin, gamma-glutamyl-transpeptidase (GGT), and total bilirubin (Fibrotest), and ALT (Actitest) were compared with liver histology. The primary outcomes were A2-A3 activity and F2-F4 fibrosis (METAVIR). RESULTS Two hundred and nine patients were included. Forty-one patients (20%) had A2-A3 activity and 61 (29%) had F2-F4 fibrosis. AST and GGT (P<0.001) were independently associated with A2-A3 activity. AST, ALT, and Actitest accurately predicted activity ((areas under receiver operating characteristic (ROC) curves (AUROC), 0.81-0.82+/-0.04)); an AST or ALT< or =30IU/l excluded significant activity with 96% certainty. Fibrotest accurately predicted F2-F4 fibrosis (AUROC, 0.78+/-0.04). Fibrotest scores (range, 0-1.0) < or =0.20 and >0.80 had negative and positive predictive values of 92%, respectively. Restricting biopsy to patients with intermediate scores (>0.20 and < or =0.80) may prevent liver biopsies in 46% of patients while maintaining 92% accuracy. CONCLUSIONS The aminotransferases and an index including five biochemical markers are accurate noninvasive markers of HBV-related activity and fibrosis, respectively.

Abstract
BACKGROUND Several studies found a high incidence rate of neuro-psychiatric complications during long-term therapy with interferon alpha (IFNalpha), e.g. slowness, severe fatigue, hypersomnia, lethargy, depressed mood, mnemonic troubles, irritability, short temper, emotional lability, social withdrawal, and lack of concentration. The aim of this study was to examine the incidence of depressed mood and major depression in patients who were treated with IFNalpha. METHODS 30 patients, affected by chronic active C-hepatitis, have been evaluated at baseline and 3 months after IFNalpha treatment. The evaluation consisted of psychometric assessments employing the DSM-IV criteria and the Montgomery Asberg Depression Rating Scale (MADRS). RESULTS At end-point, 40.7% of the patients suffered from a full blown major depression, according to the DSM-IV criteria for major depression. IFNalpha treatment induced a significant increase in the MADRS score from baseline to 3 months later. The MADRS items which were significantly increased at end-point were: expressed and unexpressed sadness; irritability; insomnia; loss of appetite; and asthenia. DISCUSSION The results show that prolonged IFNalpha treatment may induce depressive symptoms and major depression in a considerable number of subjects.

Abstract
Laminin P1 (pepsin-resistant fragment of laminin) and aminoterminal peptide of type III procollagen are measurable in serum and are now considered useful serum markers of fibrogenesis and inflammation in chronic liver diseases. However, very few studies thus far have focused on assessing the diagnostic value of these markers in detecting fibrosis and necro-inflammatory activity in chronically diseased liver. The aim of the present study was therefore to investigate the correlations of laminin and type III procollagen with liver histology and to compare their diagnostic value in detecting the degree of liver fibrosis and necro-inflammatory activity in a homogeneous group of 99 patients suffering from chronic hepatitis C, and lacking other factors which can directly affect the serum levels of the two markers. Both these serum markers were measured by radioimmunoassay, employing commercially available kits. The three main aspects of liver pathology, i.e. portal-periportal activity, lobular activity and fibrosis, were histologically evaluated and semiquantitatively expressed by numerical scores. The results of this study show that laminin and type III procollagen were both positively correlated with the histological scores for portal-periportal activity and with those for fibrosis, whereas no significant correlation was observed between each of the two serum markers and the histological scores for lobular activity. The sensitivity and specificity of laminin and type III procollagen in detecting histological aspects of fibrosis and disease activity in liver, computed at various cut-off levels, showed overlapping trends for the two markers; however, the diagnostic value was in general rather low, whatever the cut-off considered. We therefore conclude that the 'static' measurement of both serum laminin and type III procollagen is of limited value for individual diagnosis of liver damage.

Abstract
BACKGROUND The first step of colorectal carcinoma spread depends on the ability of the tumor cells to degrade and invade the extracellular matrix (ECM). The objectives of the current study were to evaluate the serum pattern of laminin, C-terminal peptide of Type I (PIP), and N-terminal peptide of Type III (PIIIP) procollagens, markers of ECM synthesis, in the follow-up of patients after resection for colorectal carcinoma and to evaluate their role in predicting local recurrence or metastases. METHODS A total of 32 patients who had undergone resection for colorectal carcinoma were followed for a median period of 24 months (range, 6-36 months). Every 3 months, laminin, PIP, and PIIIP were measured in the sera together with the tumor markers carcinoembryonic antigen (CEA), CA 19-9, and tissue plasminogen activator (TPA). Twenty-one patients (Group 1) had no signs of recurrence, whereas the remaining 11 (Group 2) developed hepatic (n = 7) or pulmonary (n = 4) metastases. RESULTS No variations were observed in either group for laminin, CEA, CA 19-9, or TPA, whereas significant increases in PIP and PIIIP were observed in both groups 3 months after surgery. The increase in PIP and PIIIP at the 3-month follow-up was significantly greater in Group 1 than in Group 2. The difference between values at 3 months and basal values enabled a discrimination between Group 1 and Group 2, with a sensitivity of 36% and 91% and a specificity of 71% and 71% for PIP and PIIIP, respectively. CONCLUSIONS The authors believe PIIIP is useful as an early prognostic indicator of recurrence in the follow-up of patients who have undergone radical resection for colorectal carcinoma.
