INTRODUCTION: Alcoholic liver disease is one of the major causes of premature deaths worldwide. Alcohol induced liver injury is the most prevalent cause of liver disease and effects 10% to 20% of population worldwide. Alcoholic liver disease comprises a wide spectrum of pathological changes ranging from steatosis, alcoholicsteato-hepatitis, Cirrhosis and nally hepatocellular carcinoma. Our aims in this study are to detect this change by non invasive method by liver broscan and its clinical implications. MATERIALS AND METHODS: Total 200 patients were taken for observational study, conducted at Coochbehar Government Medical college and hospital both outpatient department and indoor patients from May 2019 to January 2020. Liver stiffness was assessed by ultrasound based method of transient elastography using Fibroscan machine. Gradation of liver stiffness was expressed in kilopascals (KPa). RESULTS: Maximum number of patients of alcoholic liver disease were between 40 - 49 years of age (42.5%). Male patients is 87.5% and female patients 12.5%. distribution of Rural population is 36 % and Urban population is 64%. Majority of population85 patients (42.5%) had fatty liver and 40 patients (20%) have hepatomegaly, 41 patients (20.5%) had Coarse echotexture of liver parenchyma and 54 patients (27%) had Splenomegaly, 62 patients (31%) had Nodular liver and 62 patients. It is observed that 11 patients (5.5%) had Fibroscan score ≤7.5 and 47 patients (23.5%) had broscan score 7.6 -9.9 and 40 patients (20%) had broscan score 10-12.4, 36 patients (18 %) had broscan score 12.5 – 14.6 and 66 patients (33%) have broscan score ≥ 14.7. CONCLUSIONS: Transient Elastography (TE) is a newer non invasive assessment technique to detect the progression of brosis or brosis in alcoholic liver disease patient. Major advantage is it is noninvasive (costeffective) so that we can early detect progression of this cirrhosis and can give efforts to halt the disease progression.

Liver fibrosis should be assessed in all individuals with chronic liver disease as it predicts the risk of future liver-related morbidity and thus need for treatment, monitoring and surveillance. Non-invasive fibrosis tests (NITs) overcome many limitations of liver biopsy and are now routinely incorporated into specialist clinical practice. Simple serum-based tests (eg, Fibrosis Score 4, non-alcoholic fatty liver disease Fibrosis Score) consist of readily available biochemical surrogates and clinical risk factors for liver fibrosis (eg, age and sex). These have been extensively validated across a spectrum of chronic liver diseases, however, tend to be less accurate than more ‘complex’ serum tests, which incorporate direct measures of fibrogenesis or fibrolysis (eg, hyaluronic acid, N-terminal propeptide of type three collagen). Elastography methods quantify liver stiffness as a marker of fibrosis and are more accurate than simple serum NITs, however, suffer increasing rates of unreliability with increasing obesity. MR elastography appears more accurate than sonographic elastography and is not significantly impacted by obesity but is costly with limited availability. NITs are valuable for excluding advanced fibrosis or cirrhosis, however, are not sufficiently predictive when used in isolation. Combining serum and elastography techniques increases diagnostic accuracy and can be used as screening and confirmatory tests, respectively. Unfortunately, NITs have not yet been demonstrated to accurately reflect fibrosis change in response to treatment, limiting their role in disease monitoring. However, recent studies have demonstrated lipidomic, proteomic and gut microbiome profiles as well as microRNA signatures to be promising techniques for fibrosis assessment in the future.

Abstract Purpose ElastPQ is a new elastography technique for non-invasive liver fibrosis staging. However, it does not have validated reliability criteria. We tested the reliability of a different number of measurements in patients with chronic liver disease and explored whether the application of quality criteria improves the diagnostic performance. Materials and Methods All patients underwent liver stiffness assessment (LSM) with ElastPQ and Fibroscan (F-TE). The mean, median, standard deviation (SD) and interquartile range (IQR) of 10, 5 and 3 measurements were retrospectively collected for each patient and compared to each other. Liver histology was available in a subset of patients. Results Overall, 400 patients met the inclusion criteria. Non-alcoholic fatty liver disease (NAFLD) was the most represented etiology (75 %), followed by primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH). The correlation of medians was significantly better between 10 and 5 measurements than between 10 and 3. The difference of medians was significant only in the comparison between 10 and 3 measurements. The correlation between ElastPQ and F-TE was equally good for 10 and 5 measurements and significantly improved after an IQR/median ≤ 30 % was applied. The diagnostic performance of ElastPQ was better with the median value of 10 and 5 measurements and improved if LSM values were obtained with IQR/M ≤ 30 %. Conclusion The median value of 5 valid LSMs suffices for the reliable estimation of liver stiffness using ElastPQ. The quality criterion of IQR/M ≤ 30 % should also be followed when using this technique.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. This study aimed to evaluate the performance of four ultrasound-based techniques for the non-invasive multiparametric (MPUS) assessment of liver fibrosis (LF), steatosis (HS), and inflammation in patients with NAFLD. We included 215 consecutive adult patients with NAFLD (mean age: 54.9 ± 11.7; 54.5% were male), in whom LF, HS, and viscosity were evaluated in the same session using four new ultrasound-based techniques embedded on the Aixplorer MACH 30 system: ShearWave Elastography (2D-SWE.PLUS), Sound Speed Plane-wave UltraSound (SSp.PLUS), Attenuation Plane-wave UltraSound (Att.PLUS), and Viscosity Plane-wave UltraSound (Vi.PLUS). Transient Elastography (TE) with Controlled Attenuation Parameter (CAP) (FibroScan) were considered as control. All elastographic measurements were performed according to guidelines. Valid liver stiffness measurements (LSM) were obtained in 98.6% of patients by TE, in 95.8% of patients by 2D-SWE.PLUS/Vi.PLUS, and in 98.1% of patients by Att.PLUS/SSp.PLUS, respectively. Therefore, 204 subjects were included in the final analysis. A strong correlation between LSMs by 2D-SWE.PLUS and TE (r = 0.89) was found. The best 2D-SWE.PLUS cut-off value for the presence of significant fibrosis (F ≥ 2) was 7 kPa. Regarding steatosis, SSp.PLUS correlated better than Att.PLUS with CAP values: (r = −0.74) vs. (r = 0.45). The best SSp.PLUS cut-off value for predicting the presence of significant steatosis was 1524 m/s. The multivariate regression analysis showed that Vi.PLUS values were associated with BMI and LSM by 2D-SWE.PLUS. In conclusion, MPUS was useful for assessing fibrosis, steatosis, and inflammation in a single examination in patients with NAFLD.

Background: Nonalcoholic steatohepatitis (NASH) is a metabolic disease associated with liver failure and cancer. Accurate monitoring of advancing NASH is challenging. There are few reliable, non-invasive biomarkers of early NASH. Since liver inflammation is a main driver of fibrosis, we investigated relationships between circulating components of the interleukin-6 signaling pathway (IL-6, sIL-6R and sgp130) and liver pathology in subjects with NAFLD and NASH. Methods: Predictive performance of plasma IL-6, sIL-6R and sgp130 were investigated in two independent cohorts: 1) patients with biopsy-confirmed NASH (n=49), where magnetic resonance spectroscopy (MRS), imaging (MRI) and elastography (MRE) assessed liver fat, volume and stiffness; and 2) patients with morbid obesity (n=245) undergoing bariatric surgery where Bedossa algorithm and steatosis, activity, and fibrosis scores assessed NASH severity. Correlations were evaluated between circulating IL-6, sIL-6R and sgp130 and anthropomorphic characteristics, plasma markers of metabolic disease or liver pathology, adjusting for covariates of liver disease such as age, sex, BMI and diabetes. Results: In patients with NASH, plasma IL-6 and sgp130 strongly correlated with liver stiffness, which for sgp130, was independent of age, sex, BMI, and chronic disease (diabetes, hyperlipidemia, hypertension or history of HCC). Plasma sgp130 was the strongest predictor of liver stiffness compared to commonly used biomarkers and predictive algorithms. Plasma sIL-6R correlated with liver volume independent of age, sex, and BMI. In stepwise forward regression analysis, plasma sgp130 followed by NAFLD fibrosis score and plasma globulin, predicted up to 74% of liver stiffness with/without adjustment for sex. In morbidly obese subjects, circulating IL-6 correlated with hepatocellular ballooning and sgp130 correlated with advanced liver fibrosis. Conclusions: Circulating sgp130 could represent a robust biomarker of active NASH and may be used alone or in combination with other biomarkers as a non-invasive measure of liver disease severity.

Background: Non-alcoholic Fatty Liver Disease (NAFLD) is common in HIV-infected individuals. Liver biopsy remains the gold-standard procedure for the diagnosis of liver fibrosis, but both Transient Elastography (TE) and Non-invasive Biomarkers (NIBMs) have emerged as alternatives. Objectives: Our study’s aim was to validate commonly used NIBMs for the assessment of liver fibrosis in a cohort of Greek HIV-mono-infected patients. Methods: Inclusion criteria were confirmed HIV-infection and age>18 years and exclusion criteria HBV or HCV seropositivity, liver disease other than NAFLD, alcohol abuse, ascites, transaminases levels>4xULN(upper limit of normal) and Body-Mass index(BMI)>40. Liver stiffness (LS) measurement with TE and thorough laboratory work up and medical history were acquired at study entry. FIB-4, APRI, NFS, BARD, Forns and Lok scores were calculated for each patient. Results: A total of 157 patients were eligible for this study. Significant liver fibrosis, compatible with Metavir score of F3-F4, was found in only 11(7%) patients. These findings were in accordance with those of the NIBMs; the BARD score constituting the only exception, allocating 102(65%) patients as having significant liver fibrosis. In order to obtain a balance between sensitivity and specificity new cut-offs for each NIBM were calculated; FIB-4 score yielded the best results, since by changing the cut-off to 1.49 a sensitivity and specificity balanced for both close to 85% was achieved. Conclusions: Our findings suggest that NIBMs can be used for the evaluation of liver fibrosis in HIV mono-infected patients. New cut-offs for NIBMs should probably be calculated, to help distinguishing patients with significant from those with mild/no fibrosis.

Pediatric obesity has become a major public health problem worldwide, resulting in a wide spectrum of systemic complications. Liver disease associated with obesity, also known as nonalcoholic fatty liver disease (NAFLD), is currently the most common chronic liver condition in children. Therefore, its timely and proper diagnosis is essential for preventing further development of cirrhosis. Multiple studies focused on identifying the most accurate non-invasive diagnostic method for liver fibrosis or cirrhosis. Although liver biopsy remains the gold-standard in terms of this hepatopathy, elastography methods emerged as a relatively reliable alternative to liver biopsy. Thus, recent studies revealed the great importance of these non-invasive methods not only in diagnosing pediatric NAFLD, but also in its staging. MRE is commonly considered to have a greater accuracy than ultrasound-based elastography methods, but with lower availability and higher costs. Ultrasound-based elastography methods (transient elastography (TE), p-SWE, and 2-dimensional shear wave elastography (2D-SWE)) were proved to have similar accuracy in NAFLD staging. Nevertheless, multiple confounding factors account for potential challenges when using elastography for liver stiffness measurement, such as age, obesity itself (i.e., BMI), transaminase levels, or portal flow. A potential solution for facing these challenges might be represented by a complex approach based on the combination between elastography, clinical and laboratory findings. Although the studies that assessed the role of elastography in pediatric NAFLD staging are scarce, the current knowledge underlines a crucial role of these techniques taking into account their ability to distinguish between fibrosis degrees, their non-invasive patterns, lower costs and side effects when compared to liver biopsy. Therefore, elastography might become a cornerstone in staging pediatric NAFLD.
