Fahoum K, Ying X, Magahis PT, Ross J, Basu E, Shen NT, Baltich Nelson B, Brown RS, Jesudian AB. Non-invasive markers of inflammation in alcohol-associated liver disease: A scoping review. J Gastroenterol Hepatol 2024; 39:245-255. [PMID: 38054575 DOI: 10.1111/jgh.16432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 10/30/2023] [Accepted: 11/13/2023] [Indexed: 12/07/2023]
Abstract
Clinical manifestations of liver inflammation in alcohol-associated liver disease (ALD) can range from asymptomatic to severe alcoholic hepatitis. While biopsy is the gold standard for identifying liver inflammation, it is an invasive procedure with risks of bleeding, visceral damage, and infection. We aim to establish the state of the current literature on non-invasive markers of inflammation in ALD. We searched Ovid MEDLINE, Embase, and the Cochrane Library for original studies on the association between one or more non-invasive biomarker(s) and histological inflammation or hepatitis in ALD patients. Exclusion criteria were lack of histological data, abstract only, non-English-language articles, and animal studies. Two independent reviewers screened abstracts, reviewed full texts, and extracted data from included papers. Our search identified 8051 unique studies. Title and abstract screening resulted in 563 studies, and full-text screening resulted in 31 studies for final inclusion. The majority were single-center observational cohorts with an average sample size of 124. Review of these studies identified 44 unique biomarkers and 8 calculated scores associated with histological inflammation and/or hepatitis, in addition to a metabolomic panel of 468 metabolites. Six studies examined diagnostic accuracy for histological inflammation and/or hepatitis. The highest area under the receiver operating characteristic curve was 0.932 using a model based on four metabolites. This review highlights the available literature on non-invasive markers of inflammation in ALD. There is a dearth of studies that evaluate the diagnostic accuracy of these biomarkers, and larger studies are needed to confirm findings identified in small cohorts.

Abstract
Alcohol-associated hepatitis (AH) is a clinical syndrome of jaundice, abdominal pain, and anorexia due to prolonged heavy alcohol intake. AH is associated with changes in gene expression, cytokines, immune response, and the gut microbiome. There are limited biomarkers to diagnose and prognosticate in AH, but several non-invasive biomarkers are emerging. In this review, clinical risk-stratifying algorithms, promising AH biomarkers like cytokeratin-18 fragments, genetic polymorphisms, and microRNAs will be reviewed.

Diagnostic Modalities of Non-Alcoholic Fatty Liver Disease: From Biochemical Biomarkers to Multi-Omics Non-Invasive Approaches. Diagnostics (Basel) 2022; 12:diagnostics12020407.

Abstract
Non-Alcoholic Fatty Liver Disease (NAFLD) is currently the most common cause of chronic liver disease worldwide, and its prevalence is increasing globally. NAFLD is a multifaceted disorder, and its spectrum includes steatosis to steatohepatitis, which may evolve to advanced fibrosis and cirrhosis. In addition, the presence of NAFLD is independently associated with a higher cardiometabolic risk and increased mortality rates. Considering that the vast majority of individuals with NAFLD are mainly asymptomatic, early diagnosis of non-alcoholic steatohepatitis (NASH) and accurate staging of fibrosis risk is crucial for better stratification, monitoring and targeted management of patients at risk. To date, liver biopsy remains the gold standard procedure for the diagnosis of NASH and staging of NAFLD. However, due to its invasive nature, research on non-invasive tests is rapidly increasing with significant advances having been achieved during the last decades in the diagnostic field. New promising non-invasive biomarkers and techniques have been developed, evaluated and assessed, including biochemical markers, imaging modalities and the most recent multi-omics approaches. Our article provides a comprehensive review of the currently available and emerging non-invasive diagnostic tools used in assessing NAFLD, also highlighting the importance of accurate and validated diagnostic tools.

Abstract
Alcoholic hepatitis (AH) is a clinical syndrome of jaundice, abdominal pain, and anorexia due to prolonged heavy alcohol intake, and is associated with alterations in gene expression, cytokines, immune response, and the gut microbiome. Currently, we have limited biomarkers to diagnose and prognosticate in AH, but there are many novel noninvasive biomarkers under development. We evaluate the currently used algorithms to risk-stratify in AH (such as the Maddrey modified discriminant function), and discuss novel biomarkers in development, such as breath biomarkers, microRNAs, cytokeratin-18 fragments, and the AshTest. We also review the characteristics of an ideal biomarker in AH.

Abstract
Alcoholic liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are typically asymptomatic and slow-progressing but potentially fatal diseases that are common causes of liver cirrhosis and related complications. Exosomes are nano-sized extracellular vesicles that have been linked to various intercellular communication processes and can carry biological materials reflecting the state and severity of disease. In this study, shotgun proteomic analysis of the protein expression profiles of extracellular vesicles, including exosomes and microvesicles, enriched from human serum samples of 24 patients diagnosed with various fatty liver diseases was performed using liquid chromatography tandem mass spectrometry (LC-MS/MS) followed by protein identification and label-free quantification using the MaxQuant platform. A total of 329 proteins, including 190 previously reported exosome-specific proteins, were identified from four types of liver disease, where significant differences in protein expression were found in apolipoproteins, immunoglobulins, and other previously reported markers of liver disease. Principal component analysis of 61 proteins identified from MaxQuant analysis of the LC-MS/MS data provided a confident differentiation between ALD and NAFLD. SIGNIFICANCE: The current investigation revealed the difference among various types of liver disease using LC-MS/MS of exosomes enriched from human serum samples of 24 patients where the most significantly up-regulation proteins were alpha-2-macroglobulin for alcoholic hepatitis and apolipoprotein C3 for nonalcoholic fatty liver disease.

Abstract
Tout patient consommateur chronique et excessif d’alcool avec un ictère récent doit être évalué par le score de Maddrey à la recherche d’une hépatite alcoolique aiguë sévère. Les corticostéroïdes représentent le traitement de première ligne, associés à un soutien nutritionnel adapté et à une abstinence alcoolique. La combinaison corticostéroïdes plus N-acétylcystéine (perfusée pendant les cinq premiers jours) améliore la survie à court terme par rapport aux corticostéroïdes seuls, constituant une option thérapeutique de première ligne. La réponse au traitement est évaluée au septième jour par le modèle de Lille inférieur ou égal à 0,45. Le pronostic des patients non répondeurs aux corticostéroïdes avec un modèle de Lille supérieur à 0,45 est sombre avec une survie de 23 % à six mois. Pour des patients non répondeurs aux corticostéroïdes et sélectionnés, la transplantation hépatique précoce améliore significativement la survie à six mois et à long terme.

Abstract
The relationship between nonalcoholic fatty liver disease (NAFLD) and obstructive sleep apnea (OSA) has been well demonstrated, but remains to be evidenced in chronic obstructive pulmonary disease (COPD). Recently, Viglino
et al. (Eur Respir J, 2017) attempted to determine the prevalence of liver fibrosis, steatosis and nonalcoholic steatohepatitis (NASH) in COPD patients, some of whom had OSA, basing the NAFLD diagnostic on three circulating biomarker-based liver scores: the FibroTest, SteatoTest and NashTest, from the Fibromax® panel. Among the main findings, the absence of OSA treatment emerged as independently associated with liver fibrosis and steatosis, when compared to effective treatment. However, besides the low number of treated patients, no polysomnographic respiratory data was provided, making it difficult to differentiate the impact of OSA from that of COPD in NAFLD prevalence. Furthermore, NAFLD diagnosis relied exclusively on circulating biomarker-based liver scores, without histological, imagery or other liver exploratory methods. Therefore, in this article, some methodological points are reminded and discussed, including the choice of OSA measurements, and the significance of ActiTest and AshTest scores from Fibromax® in this pathophysiological context.

Abstract
The clinical presentation of alcoholic hepatitis (AH) can be mimicked by other alcoholic liver diseases. The aim of this study was to identify clinical features that predict AH on liver biopsy. Biopsies from patients hospitalized for presumed severe AH were used to identify a derivation cohort (101 patients) and validation cohort (71 patients). Using histologic scores for hepatocyte ballooning, Mallory-Denk bodies, and lobular inflammation, 95 patient biopsies (55%) were classified as definite AH, 55 (32%) as possible AH, and 22 (13%) as no AH. Survival was similar among the groups, but mortality was significantly increased for patients with fatty change ≤50% on initial liver biopsy. An analysis limited to uninfected patients with definite AH or no AH in the derivation cohort identified a greater leukocyte count at admission and radiographic evidence of liver surface nodularity as independent predictors of definite AH on biopsy (P < 0.05). In the derivation cohort, the leukocyte count thresholds for ensuring 100% specificity for diagnosing definite AH were 10 × 109/L if the liver surface was nodular and 14 × 109/L if the liver surface was smooth, with a sensitivity of 76% and an area under the receiver operator characteristic curve of 0.88. In the validation cohort, these thresholds had a specificity of 86%, a sensitivity of 59%, and an area under the receiver operator characteristic curve of 0.72. Conclusion: The combination of an elevated leukocyte count and a nodular liver surface in the absence of active infection retrospectively identified patients with a high likelihood of histologic AH for whom liver biopsy may not be necessary. For patients with suspected severe AH who do not fulfill these criteria, liver biopsy is important to exclude other variants of alcoholic liver disease. (Hepatology Communications 2017;1:1070-1084).

Abstract
UNLABELLED The diagnosis of alcoholic hepatitis (AH) often requires a transjugular liver biopsy (TJLB), a procedure that is not always readily accessible. We analyzed plasma biomarkers to estimate the presence of histological features of AH among patients with clinical suspicion of AH. Using enzyme-linked immunosorbent assay, we tested M65 and M30 (circulating fragments of cytokeratin-18) and their respective fraction carried by microvesicles (MVs), CCL20 and TREM1. Leukocyte, platelet, and endothelial-derived MVs were quantified by way of flow cytometry. Test and validation cohorts prospectively included patients with clinical features of AH undergoing TJLB. In the test cohort, 46 of 83 (55%) patients showed histological features of AH. Age, bilirubin, INR, and creatinine (ABIC) score was B or C in 83%. Patients with histologically proven AH had higher levels of total and MV-bound M65 and total and MV-bound M30 and CCL20 than those without (P < 0.001 for all tests). Levels of TREM-1 and of subpopulations of MVs were not different between groups. M65 and M30 both had an area under the receiver operating characteristics curve of 0.84 to estimate the presence of AH. For M65, a cutoff of 2000 IU/L had a positive predictive value of 91%, whereas a cutoff of 641 IU/L had a negative predictive value of 88%. In the validation cohort, AH was histologically confirmed in 48 of 68 (71%) patients. ABIC score was B or C in 69% of patients. For M65, the above cutoffs had a diagnostic accuracy of 81%. Even better results were obtained in patients with suspicion of severe AH (ABIC B or C) in both cohorts. CONCLUSION Plasma levels of cytokeratin-18 fragments are reliable noninvasive markers of AH. Using the proposed cutoffs for M65, two thirds of TJLB can be avoided, which can be useful in centers where this technique is not readily available. (Hepatology 2017;66:555-563).

Abstract
BACKGROUND/AIMS According to guidelines, the histological diagnosis of severe alcoholic steatohepatitis (ASH) can require liver biopsy if a specific treatment is needed. The blood test AshTest (BioPredictive, Paris, France) has been initially validated for the non-invasive diagnosis of ASH in a large population of heavy drinkers. The aim was to validate the AshTest accuracy in the specific context of use of patients with suspected severe ASH, in order to reduce the need for transjugular biopsy before deciding treatment. METHODS The reference was liver biopsy, performed using the transjugular route, classified according to its histological severity as none, minimal, moderate or severe. Biopsies were assessed by the same experienced pathologist, blinded to simultaneous AshTest results. RESULTS A total of 123 patients with severe clinical ASH (recent jaundice and Maddrey function greater or equal to 32) were included, all had cirrhosis and 80% had EASL histological definition of ASH. 95% of patients received prednisolone; and the 2-year mortality was 63%. The high AshTest performance was confirmed both for the binary outcome [AUROC = 0.803 (95%CI 0.684-0.881)] significantly higher than the AST/ALT AUROC [0.603 (0.462-0.714); P<0.001], and for the severity of ASH-score system by the Obuchowski measures for [mean (SE) 0.902 (0.017) vs. AST/ALT 0.833 (0.023); P = 0.01], as well as for the diagnosis and severity of ballooning, PMN and Mallory bodies. According to attributability of discordances, AshTest had a 2-7% risk of 2 grades misclassification. CONCLUSION These results confirmed the diagnostic performance of AshTest in cirrhotic patients with severe clinical ASH, in the specific context of use of corticosteroid treatment. AshTest is an appropriate non-invasive alternative to transjugular 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
Alcoholic liver disease (ALD) causes more than 5000 deaths per year in France. Most of those deaths could be prevented by an early diagnosis, which would give the patients the opportunity to modify their alcohol consumption while liver lesions are still reversible. Hepatic histology is the main parameter that predicts morbidity and mortality in patients with ALD. Non-invasive methods such as biomarker tests (e.g. FibroTest(®) or FibroMetre A(®)) or hepatic elastography (FibroScan(®)) may allow diagnosing alcohol-induced liver lesion without systematic biopsy. Despite promising preliminary results, those methods are not validated yet in ALD. A validation of non-invasive methods for ALD could allow a large screening of the severe forms of this pathology.

Abstract
Alcoholic hepatitis is one of the most severe presentations of alcoholic liver disease. It is usually revealed by the recent onset of jaundice in a patient with alcoholic cirrhosis. Maddrey's discriminant function can help to recognize patients with poor prognosis (the 6-month mortality is above 50% when it exceeds 32). Corticosteroids increase survival in those patients with high risk of death. Other treatments (pentoxifylline, N-acetyl-cysteine or enteral nutrition) need to be investigated further before to recommend their routine use instead of, or in association with, corticoids. Liver transplantation can be proposed to highly selected patients who do not respond to medical therapy. In any case, long-term prognosis will primarily depend on the maintenance of alcohol abstinence.

Abstract
Current guidelines recommend that all cirrhotic patients should undergo screening endoscopy at diagnosis to identify patients with varices at high risk of bleeding who will benefit from primary prophylaxis. This approach places a heavy burden upon endoscopy units and the repeated testing over time may have a detrimental effect on patient compliance. Noninvasive identification of patients at highest risk for oesophageal varices would limit investigation to those most likely to benefit. Upper GI endoscopy is deemed to be the gold standard against which all other tests are compared, but is not without its limitations. Multiple studies have been performed assessing clinical signs and variables relating to liver function, variables relating to liver fibrosis, and also to portal hypertension and hypersplenism. Whilst some tests are clearly preferable to patients, none appear to be as accurate as upper GI endoscopy in the diagnosis of oesophageal varices. The search for noninvasive tests continues.

Abstract
Background Excessive consumption of alcohol contributes to alcoholic liver disease. Fatty liver is the early stage of alcohol-related liver disease. The aim of this study was to search for specific serological biomarkers of alcoholic fatty liver (AFL) compared to healthy controls, non-alcoholic fatty liver (NAFL) and liver fibrosis in a rodent model. Methods Serum samples derived from animals with AFL, NAFL, or liver fibrosis were characterized and compared using two-dimensional differential gel electrophoresis. A matrix-assisted laser desorption ionization-time of flight tandem mass spectrometer in conjunction with mascot software was used for protein identification. Subsequently, Western blotting and flexible multi-analyte profiling were used to measure the expressions of the putative biomarkers present in the serum of animals and clinical patients. Results Eight differential putative biomarkers were identified, and the two most differentiated proteins, including upregulated C-reactive protein (CRP) and downregulated haptoglobin (Hp), were further investigated. Western blotting validated that CRP was dramatically higher in the serum of AFL compared to healthy controls and other animals with liver disease of NAFL or liver fibrosis (p < 0.05). Moreover, we found that CRP and Hp were both lower in liver fibrosis of TAA-induced rats and clinical hepatitis C virus-infected patients. Conclusion The results suggest that increased levels of CRP are an early sign of AFL in rats. The abnormally elevated CRP induced by ethanol can be used as a biomarker to distinguish AFL from normal or otherwise diseased livers.

Abstract
BACKGROUND ActiTest (AT) is a biomarker of liver necro-inflammatory histological activity validated in patients with chronic hepatitis C (HCV). AIM The aim was to assess the accuracy of AT in comparison with alanine aminotransferase (ALT) the standard of care. METHODS Methods used an integrated database of individual data and the new recommended Obuchowski measures. An updated "classical" meta-analysis of AT validation studies was also performed. The main end points were the area under the ROC curves (AUROCs) for the diagnosis of each histological activity grade defined using METAVIR scoring system. To avoid repeated tests and the spectrum effect of activity grades prevalence, the comparison of AT and ALT accuracies used the Obuchowski method. RESULTS For the individual analysis, a total of 1250 patients were included and for the meta-analysis six studies (2017 patients) were included. The overall accuracy of AT for the diagnosis of any activity grade (Obuchowski measure=0.850) was significantly higher than the accuracy of ALT (Obuchowski measure=0.837; P=0.009). The updated standard meta-analysis confirmed the accuracy of AT (p<0.0001) both in independent AUROC=0.79 (95% CI, 0.73-0.85) and in non independent studies AUROC=0.74 (95% CI, 0.67-0.81). CONCLUSIONS The accuracy of AT for grading the necro-inflammatory activity of patients with HCV was significantly higher than ALT serum activity alone, the standard biomarker.

Abstract
FibroTest (FT) is a biomarker of liver fibrosis initially validated in patients with chronic hepatitis C (CHC) and subsequently assessed in other frequent liver diseases, including chronic hepatitis B (CHB), alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD). The primary aim of the present study was to update a previous meta-analysis of FT diagnostic value, and to summarize its advantages and limitations. The secondary aim was to provide an overview of the prognostic value of FT in CHC, CHB and ALD. For diagnostic value, the main endpoint was the FT area under the ROC curves (AUROCs) for the diagnosis of bridging fibrosis (F2/F3/F4 vs F0/F1), standardized for the spectrum of fibrosis. Sensitivity analysis integrated the non-standardized observed AUROCs, the independency of authors, size (length) of biopsy, prospective design, correctness of procedures, co-morbidities, and timelag between biopsy and serum sampling. For prognostic value, the main endpoint was the FT AUROC for the prognostic value of liver complications or death related to liver disease. A total of 38 diagnostic studies were included, which pooled 7985 subjects who had undergone both FT and biopsy (4600 HCV, 1580 HBV, 267 NAFLD, 524 ALD and 1014 mixed). The mean standardized AUROC was 0.84 (95% CI, 0.83-0.86), with no differences in terms of causes of liver disease: HCV 0.84 (0.82-0.87); HBV 0.81 (0.78-0.83); NAFLD 0.84 (0.76-0.92); ALD 0.87 (0.82-0.92); and mixed 0.85 (0.81-0.89). Three prognostic studies were also included. FT was found to have higher or similar prognostic value compared with biopsy in patients with CHC, CHB or ALD. FibroTest is an effective alternative to biopsy in patients with chronic hepatitis C or B, ALD or NAFLD. Indeed, the prognostic performance of FibroTest was at least as accurate as that of biopsy in patients with chronic hepatitis C or B, or ALD.

Abstract
FibroTest has been validated as a biomarker of fibrosis in patients with chronic viral hepatitis, with a similar prognostic value as biopsy. The aim of the study was to compare the diagnostic and prognostic values of FibroTest versus the recently patented biomarkers, FibrometerA, and Hepascore. A total of 218 consecutive patients with ALD and available liver biopsy examination were included. Biomarkers were compared using univariate area under the ROC curves (AUROC) and multivariate analysis (logistic regression and Cox). The median follow-up was 8.2 years. Eighty-five patients died, including 42 deaths related to liver complications. The diagnostic values of FibrometerA and Hepascore did not differ from that of FibroTest for advanced fibrosis (all AUROC = 0.83 +/- 0.03) and cirrhosis (FibroTest and FibrometerA = 0.94 +/- 0.02, Hepascore = 0.92 +/- 0.02), and were significantly greater than those of nonpatented biomarkers (APRI, Forns, FIB4; P < 0.01). In multivariate analysis the most significant was FibroTest (P = 0.001), without independent diagnostic value for FibrometerA (P = 0.19), and Hepascore (P = 0.40). The prognostic values of FibroTest (AUROC for survival or non liver disease-related death = 0.79 +/- 0.04), FibrometerA (0.80 +/- 0.04), Hepascore (0.78 +/- 0.04), did not differ from that of biopsy fibrosis staging (0.77 +/- 0.04). In multivariate analysis the most significant were FibroTest (P = 0.004) and biopsy (P = 0.03), without independent prognostic values for FibrometerA (P = 0.41) and Hepascore (P = 0.28). In patients with alcoholic liver disease, FibrometerA and Hepascore did not improve the diagnostic and prognostic values of FibroTest.

Abstract
BACKGROUND/AIMS The aim of this study was to assess the accuracy of liver stiffness measurement (LSM) for the diagnosis of extensive fibrosis and cirrhosis in patients with alcoholic liver disease (ALD). METHODS One hundred and seventy-four patients with ALD were enrolled in four liver units and underwent concomitant liver biopsy and LSM. Fibrosis was assessed using the Brunt et al. and the Chevallier et al. scoring systems. Steatosis and histological alcoholic hepatitis (HAH) were quoted in classes. RESULTS Twenty-seven patients had inadequate biopsy or LSM. Distribution in 147 patients according to the Brunt score (median LSM) was: F1: n=13 (5.7kPa); F2: n=24 (8.3kPa); F3: n=31 (17.5kPa) and F4: n=79 (40.9kPa) (P<0.0001). LSM was correlated with the amount of fibrosis according to the Chevallier score (r=0.70, P<0.0001). LSM was correlated to fibrosis stage (tau beta, 0.53; P<0.0001) and HAH (tau beta, 0.30; P<0.0001). In multivariate analysis, fibrosis was the only parameter correlated with LSM. The areas under the ROC curve were 0.94 and 0.87 for the diagnosis of extensive fibrosis (Brunt et al. score > or =3) and cirrhosis, respectively (threshold-values: 12.9 and 22.6kPa). CONCLUSIONS LSM accurately assesses extensive fibrosis and cirrhosis in alcoholic patients.

Abstract
Liver biopsy, due to its limitations and risks, is an imperfect gold standard for assessing the severity of the most frequent chronic liver diseases. This chapter summarized the advantages and the limits of the available biomarkers of liver fibrosis. Among a total of 2237 references, a total of 14 validated biomarkers have been identified between 1991 and 2007. Nine were not patented and five were patented. FibroTest (FT) was the most studied test with 33 different populations including 6549 patients and 925 controls. The mean diagnostic value for the diagnosis of advanced fibrosis assessed using standardized area under the receiver operating characteristics (ROC) curves was 0.84 [95% confidence interval (CI), 0.83-0.86], without significant difference between the causes of liver disease, hepatitis C, hepatitis B, alcoholic or nonalcoholic fatty liver disease. High-risk profiles of false negative/positive of FT are present in 3% of populations, mainly Gilbert syndrome, hemolysis, and acute inflammation. FT has higher accuracy than aspartate aminotransferase/platelets ratio index (APRI), the most used nonpatented test. No significant difference has been observed between the five patented tests. A quality score has been assessed in order to compare the quality of fibrosis biomarkers. Neither biomarkers nor biopsy are sufficient alone to take definitive decision in a given patient and all the clinical and biological data must be taken into account. Due to the evidence-based data, health authorities in some countries have already approved validated biomarkers as first-line procedure for the staging of liver fibrosis. This overview of evidence-based data suggests that biomarkers could be used as an alternative to liver biopsy for the assessment of fibrosis stage in the four more common chronic liver diseases: C virus (HCV), hepatitis B virus (HBV), hepatitis nonalcoholic fatty liver disease (NAFLD), and alcoholic liver disease (ALD). Neither biomarkers nor biopsy are sufficient alone to take definitive decision in a given patient and all the clinical and biological data must be taken into account.

Abstract
BACKGROUND/AIMS Specific markers for differentiation of nonalcoholic (NASH) from alcoholic steatohepatitis (ASH) are lacking. We investigated the role of routine laboratory parameters in distinguishing NASH from ASH. METHODS Liver biopsies performed at our hospital over a 10-year period were reviewed, 95 patients with steatohepatitis identified and their data prior to biopsy reevaluated. The diagnosis NASH or ASH was assigned (other liver diseases excluded) on the basis of the biopsy and history of alcohol consumption (< 140 g/week). Logistic regression models were used for analysis. RESULTS NASH was diagnosed in 58 patients (61%; 30 f) and ASH in 37 (39%; 9 f). High-grade fibrosis (59% vs. 19%, P < 0.0001) and an AST/ALT ratio > 1 (54.1% vs 20.7%, P = 0.0008) were more common in ASH. The MCV was elevated in 53% of ASH patients and normal in all NASH patients (P < 0.0001). Multivariate analysis identified the MCV (P = 0.0013), the AST/ALT ratio (P = 0.011) and sex (P = 0.0029) as relevant regressors (aROC = 0.92). The AST/ALT ratio (P < 0.0001) and age (P = 0.00049) were independent predictors of high-grade fibrosis. Differences in MCV were more marked in high-grade fibrosis. CONCLUSIONS Higher MCVs and AST/ALT ratios in ASH reflect the severity of underlying liver disease and do not differentiate NASH from ASH. Instead, these biomarkers might prove useful in guiding selection of patients for liver biopsy and in targeting therapy.

Abstract
Although per capita alcohol consumption, and thus the prevalence of alcoholic liver disease, decreases generally with age in Europe and in the United States, recently an increase in alcohol consumption has been reported in individuals over 65 years. Reasons explaining this observation may include an increase in life expectancy or a loss of life partners and, thus, loneliness and depression. Although ethanol metabolism and ethanol distribution change with age, and an elderly person's liver is more susceptible to the toxic effect of ethanol, the spectrum of alcoholic liver diseases and their symptoms and signs is similar to that seen in patients of all ages. However, prognosis of alcoholic liver disease in the elderly is poor. In addition, chronic alcohol consumption may enhance drug associated liver disease and may also act as a cofactor in other liver diseases, such as viral hepatitis and nonalcoholic fatty liver disease.

Abstract
BACKGROUND FibroTest (FT) is a biomarker of liver fibrosis initially validated in patients with chronic hepatitis C (CHC). The aim was to test two hypotheses, one, that the FT diagnostic value was similar in the three other frequent fibrotic diseases: chronic hepatitis B (CHB), alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD); and the other, that the FT diagnostic value was similar for intermediate and extreme fibrosis stages. METHODS The main end points were the FT area under the ROC curves (AUROCs) for the diagnosis of bridging fibrosis (F2F3F4 vs. F0F1), standardized for the spectrum of fibrosis stages, and the comparison of FT AUROCs between adjacent stages. Two meta-analyses were performed: one combining all the published studies (random model), and one of an integrated data base combining individual data. Sensitivity analysis integrated the independency of authors, lenght of biopsy, prospective design, respect of procedures, comorbidities, and duration between biopsy and serum sampling. RESULTS A total of 30 studies were included which pooled 6,378 subjects with both FT and biopsy (3,501 HCV, 1,457 HBV, 267 NAFLD, 429 ALD, and 724 mixed). Individual data were analyzed in 3,282 patients. The mean standardized AUROC was 0.84 (95% CI, 0.83-0.86), without differences between causes of liver disease: HCV 0.85 (0.82-0.87), HBV 0.80 (0.77-0.84), NAFLD 0.84 (0.76-0.92), ALD 0.86 (0.80-0.92), mixed 0.85 (0.80-0.93). The AUROC for the diagnosis of the intermediate adjacent stages F2 vs. F1 (0.66; 0.63-0.68, n = 2,055) did not differ from that of the extreme stages F3 vs. F4 (0.69; 0.65-0.72, n = 817) or F1 vs. F0 (0.62; 0.59-0.65, n = 1788). CONCLUSION FibroTest is an effective alternative to biopsy in patients with chronic hepatitis C and B, ALD and NAFLD. The FT diagnostic value is similar for the diagnosis of intermediate and extreme fibrosis stages.

Abstract
Among the noninvasive alternatives to liver biopsy, several studies have demonstrated the predictive value and a better benefit-to-risk ratio than biopsy of five combinations of simple serum biochemical markers (the super combination being FibroMAX (BioPredictive, Paris, France) in patients at risk of chronic liver diseases: FibroTest (BioPredictive) for the quantitative assessment of fibrosis; SteatoTest (BioPredictive) for the quantitative assessment of steatosis; ActiTest (BioPredictive) for the quantitative assessment of necroinflammatory activity in chronic viral hepatitis C and B; NashTest (BioPredictive) for the categorical diagnosis of nonalcoholic steatohepatitis; and AshTest for the quantitative assessment of alcoholic steatohepatitis (also known in the USA as HCV-FibroSURE, HBV-FibroSURE, ASH-FibroSURE and NASH-FibroSURE; LabCorp, NC, USA). The possible causes of false-negative and false-positive results are also better identified. These tests, which are now available in 50 countries, can facilitate the screening and management of the most frequent liver diseases.

Abstract
BACKGROUND The best technique to estimate portal hypertension (PHT) is to measure the hepatic venous pressure gradient (HVPG), which is an invasive method. AIM To assess the relationship between the Fibrotest (Biopredictive, Paris, France) and the presence and degree of PHT in patients with liver disease, and to determine if the Fibrotest can diagnose severe PHT, defined by HVPG >or= 12 mmHg, in cirrhotic patients. METHODS Patients who underwent a transjugular liver biopsy were prospectively included. HVPG was measured, and classification of histological lesions assessed. The same day, blood samples for Fibrotest were performed. RESULTS A total of 130 patients were included (no or minimal fibrosis: 12%, moderate fibrosis 17%, cirrhosis 71%). There was a significant correlation between Fibrotest and HVPG (Pearson correlation coefficient = 0.58, P < 0.0001), also weaker in cirrhotic patients (Pearson correlation coefficient = 0.24, P = 0.02). In cirrhotic patients, Fibrotest was significantly higher when there was a severe PHT (0.87 +/- 0.15 vs. 0.73 +/- 0.14, respectively, P = 0.02). The areas under the receiver operating characteristic curves for the diagnosis of severe PHT was 0.79 +/- 0.07, not different from that of platelets and Child-Pugh score. CONCLUSION In patients with liver disease or cirrhosis, Fibrotest is correlated with the presence and degree of PHT. Other studies are needed to confirm these results, especially in non-decompensated cirrhotic patients.

Abstract
PURPOSE OF REVIEW This review aims to acquaint the reader with advances in 2006 in the epidemiology, genetics, detection, pathogenesis and treatment of alcoholic liver disease. RECENT FINDINGS Important discoveries have been made in pathogenesis and mechanism of disease, with great emphasis on the many pathways leading to oxidative stress, and the novel mechanism of endoplasmic reticulum stress that is proving to be important in the pathogenesis of many liver diseases. The reliability of ethyl glucuronide and other biomarkers for the detection of alcohol abuse is being better established. There have been no treatment advances for alcoholic liver disease but, on balance, steroids are still favored for carefully selected patients with alcoholic hepatitis. Many compounds tested in rodents may now be available for consideration for clinical trials. Criteria for patient selection and refusal for liver transplantation are being established but the 6 months abstinence rule still holds. SUMMARY Insights are being made into the pathogenesis of alcoholic liver disease but safe and effective therapies for both alcoholic hepatitis and alcoholic cirrhosis have yet to be discovered.

Abstract
Alcohol excess is associated with a spectrum of disease ranging from simple steatosis through steatohepatitis to cirrhosis and, in some, hepatocellular carcinoma. Alcoholic steatohepatitis itself has a variable histological picture, but a constant feature is the presence of ballooning degeneration of hepatocytes. Recent studies have emphasized the importance of apoptosis as a mechanism of cell death in this condition. It is accompanied by varying degrees of perivenular, centrilobular, and pericellular fibrosis. When severe and associated with perivenular liver cell necrosis (central sclerosing hyaline necrosis), there may be precirrhotic portal hypertension. The pattern of fibrosis may initially be diffuse with little nodule formation, but in time there is frequently the development of a micronodular cirrhosis. In approximately 15% of patients with established cirrhosis, hepatocellular carcinoma develops; several precursor lesions are now recognized which can be detected histologically. Several authors have drawn attention to additional components of the spectrum of alcoholic liver disease, including vascular changes, portal tract inflammation and fibrosis, ductular reaction, and iron overload. The morphology of alcoholic liver disease can be significantly affected by abstinence; furthermore, the clinical and morphological phenotype can be significantly influenced by the presence of comorbid conditions such as nonalcoholic fatty liver disease or viral hepatitis. Biopsy appearances can provide important prognostic information in alcoholic liver disease, and this review incorporates a proposed grading and staging schema for assessment of histological severity.

Abstract
Alcoholic hepatitis is a disease with a wide range of severity. Patients with severe disease have short-term mortality rates above 35%. In these high-risk patients, pharmacologic therapy is an important adjunct to supportive medical care and has been proved to improve survival. Given the benefit of drug treatment, it is important to identify patients at risk of early mortality from alcoholic hepatitis. A number of validated scoring systems are useful for this purpose, including the Maddrey Discriminant Function, the Model of End-Stage Liver Disease score, and the Glasgow Alcoholic Hepatitis score. Patients judged by one or more of these criteria to have severe alcoholic hepatitis should be treated with corticosteroids or pentoxifylline, provided they have no contraindications for this treatment. Adequate nutrition is also critical and should be provided by tube feeding if necessary. A prompt decline in serum bilirubin indicates a favorable response to therapy. Patients who do not exhibit a reduction in serum bilirubin within 1 week are considered nonresponders and have a 6-month mortality rate of 50% or higher.

Abstract
BACKGROUND Mortality related to complications of cirrhosis is increasing in patients with insulin-resistance factors. Hyperlipidaemic patients have multiple risk factors of insulin resistance. It is impossible to perform liver biopsy in such a large number of hyperlipidaemic patients to identify patients with advanced liver fibrosis or with steatohepatitis (non-alcoholic steatohepatitis, NASH). AIMS To use the non-invasive biomarkers, FibroTest (FT), SteatoTest and NashTest, and to assess the prevalence of advanced liver disease in a large population of hyperlipidaemic patients. METHODS A consecutive cohort of hyperlipidaemic patients was followed prospectively in a lipid centre and the sera were analysed retrospectively. RESULTS A total of 2834 subjects were included: 1909 hyperlipidaemic patients and 925 blood donors (BD). Advanced fibrosis was identified by FT in 53/1909 (2.8%) hyperlipidaemic patients vs. 0/925 BD (0%) (P < 0.0001); advanced steatosis in 569/1893 hyperlipidaemic patients (30.1%) vs. 8/164 (4.9%) BD (P < 0.0001) and NASH in 132/1893 (7%) vs. 0/164 (0%), respectively (P < 0.0001). There was a highly significant and linear association between the number of metabolic syndrome factors and liver disease prevalence - the highest being for type 2 diabetics: advanced steatosis 66%, NASH 24% and advanced fibrosis 6%. CONCLUSIONS The prevalence of fibrosis, steatosis and NASH in hyperlipidaemic patients appears to be high (3%, 30% and 7%, respectively). Biomarkers could be useful for screening of advanced fibrosis and NASH in patients with several metabolic syndrome factors, to prevent liver mortality.

Abstract
Background Liver biopsy is considered the gold standard for assessing histologic lesions of non-alcoholic fatty liver disease (NAFLD). The aim was to develop and validate a new biomarker of non alcoholic steato hepatitis (NASH) the NashTest (NT) in patients with NAFLD. Methods 160 patients with NAFLD were prospectively included in a training group, 97 were included in a multicenter validation group and 383 controls. Histological diagnoses used Kleiner et al's scoring system, with 3 classes for NASH: "Not NASH", "Borderline", "NASH"). The area under the ROC curves (AUROC), sensitivity (Se), specificity (Sp), and positive and negative predictive values (PPV, NPV) were assessed. Results NT was developed using patented algorithms combining 13 parameters: age, sex, height, weight, and serum levels of triglycerides, cholesterol, alpha2macroglobulin, apolipoprotein A1, haptoglobin, gamma-glutamyl-transpeptidase, transaminases ALT, AST, and total bilirubin. AUROCs of NT for the diagnosis of NASH in the training and validation groups were, respectively, 0.79 (95%CI 0.69–0.86) and 0.79 (95%CI 0.67–0.87; P = 0.94); for the diagnosis of borderline NASH they were: 0.69 (95%CI 0.60–0.77) and 0.69 (95%CI 0.57–0.78; P = 0.98) and for the diagnosis of no NASH, 0.77 (95%CI 0.68–0.84) and 0.83 (95%CI 0.67–0.90; P = 0.34). When the two groups were pooled together the NashTest Sp for NASH = 94% (PPV = 66%), and Se = 33% (NPV = 81%); for borderline NASH or NASH Sp = 50% (PPV = 74%) and Se = 88% (NPV = 72%).
