The role of elastography in alcoholic liver disease: fibrosis staging and confounding factors, a review of the current literature.

Introduction: Alcohol-related liver disease (ALD) was estimated to have a prevalence of 2% among the USA population. Since severe fibrosis in compensated patients is the main predictor of long-term survival, it is of utmost importance to early detect patients with severe fibrosis before decompensation occurs. Liver elastography has been used to stage liver fibrosis.

Clinical profile and outcome of glycogen storage disease in Indian children.

We aimed to determine the clinical profile and outcome of Indian children with glycogen storage disorders. Ours was a retrospective study from 2005 to 2018 in 36 children diagnosed on the basis of a liver biopsy. Most (77.

Optimization of Point-Shear Wave Elastography by Skin-to-Liver Distance to Assess Liver Fibrosis in Patients Undergoing Bariatric Surgery.

Background: Obesity is a primary limiting factor in liver stiffness measurement (LSM). The impact of obesity has always been evaluated in terms of body mass index (BMI), without studying the effects of skin-to-liver distance (SLD) on LSM. We studied the impact of SLD on LSM in a cohort of obese patients undergoing bariatric surgery and intra-operatory liver biopsy.

Spontaneous porto-femoral shunting in long-standing portal hypertension.

Spontaneous portosystemic shunting is a compensation mechanism that is supposed to relieve the portal circulation from high pressures. Here we report an unusual shunt that originates from a patent paraumbilical vein and reaches the femoral vein via the inferior epigastric vein. Despite being merely anecdotal, this finding is fascinating from an anatomical point of view.

Spleen stiffness can be employed to assess the efficacy of spontaneous portosystemic shunts in relieving portal hypertension.

Introduction: Spleen stiffness (SS) has been found to mirror dynamic changes in portal pressure after transjugular intrahepatic portosystemic shunt (TIPS) placement. However, there is no data available regarding SS in patients with spontaneous portosystemic shunting (SPSS), especially in regards to prediction of hepatic decompensation.

Methods: We retrospectively selected patients with confirmed SPSS and esophageal varices (EVs) at endoscopic examination, and recorded any decompensating event (i.

Sociodemographic risk factors for hepatitis C virus infection in a prospective cohort study of 257 persons in Canada who inject drugs.

Background: Approximately 60% of incident hepatitis C virus (HCV) infections are due to intravenous drug use; therefore, understanding the socio-demographics of people who inject drugs (PWID) is necessary to achieve HCV elimination.

Methods: In this prospective cohort study of PWID, we determined patients' baseline HCV antibody, hepatitis B virus (HBV), and HIV serological status. HCV antibody- negative (anti-HCV-negative) cases were followed for seroconversion (median 17 mo with q3m testing) as part of a larger study to develop a vaccine for HCV.

aMAP risk score predicts hepatocellular carcinoma development in patients with chronic hepatitis.

Background & Aims: Hepatocellular carcinoma (HCC) is the leading cause of death in patients with chronic hepatitis. In this international collaboration, we sought to develop a global universal HCC risk score to predict the HCC development for patients with chronic hepatitis.

Methods: A total of 17,374 patients, comprising 10,578 treated Asian patients with chronic hepatitis B (CHB), 2,510 treated Caucasian patients with CHB, 3,566 treated patients with hepatitis C virus (including 2,489 patients with cirrhosis achieving a sustained virological response) and 720 patients with non-viral hepatitis (NVH) from 11 international prospective observational cohorts or randomised controlled trials, were divided into a training cohort (3,688 Asian patients with CHB) and 9 validation cohorts with different aetiologies and ethnicities (n = 13,686).

An expert review on the use of tenofovir alafenamide for the treatment of chronic hepatitis B virus infection in Asia.

Asia has intermediate-to-high prevalence and high morbidity of hepatitis B virus (HBV) infection. The use of guideline-recommended nucleos(t)ide analogs with high barrier to resistance, such as entecavir (ETV), tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF), is one of the key interventions for curbing HBV infection and associated morbidity in Asia. However, there are some challenges to the use of ETV and TDF; while ETV is associated with high resistance in lamivudine (LAM)-exposed (especially LAM-refractory) patients; bone and renal safety issues are a major concern with TDF.

Dyslipidemia as a risk factor for liver fibrosis progression in a multicentric population with non-alcoholic steatohepatitis.

Nonalcoholic fatty liver disease (NAFLD) is a serious worldwide health problem, with an estimated global prevalence of 24%; it has a notable relationship with other metabolic disorders, like obesity and type 2 diabetes mellitus (T2DM). Nonalcoholic steatohepatitis (NASH) is one of the most important clinical entities of NAFLD, which is associated with an increased risk of progression to liver cirrhosis and hepatocellular carcinoma (HCC). Mexico is one of the countries with the highest prevalence of metabolic diseases; therefore, we sought to investigate the impact that these clinical entities have in the progression to advanced fibrosis in Mexican patients with NASH.

Similar risk of hepatocellular carcinoma during long-term entecavir or tenofovir therapy in Caucasian patients with chronic hepatitis B.

Background & Aims: A recent study in Asian patients with chronic hepatitis B (CHB) reported that the incidence of hepatocellular carcinoma (HCC) was lower in patients treated with tenofovir disoproxil fumarate (TDF) than entecavir (ETV), but this finding remains controversial. We aimed to identify any differences in HCC incidence, or other patient outcomes, between patients receiving TDF or ETV in the well monitored, multicenter European PAGE-B cohort.

Methods: We included 1,935 Caucasians with CHB, with or without compensated cirrhosis, treated with ETV (n = 772) or TDF (n = 1,163) monotherapy.

Community pharmacists' exposure to COVID-19.

Introduction: Since the beginning of the 2020 Sars-CoV-2 Italian outbreak, healthcare workers have been among the most exposed categories. There is little information about community pharmacists' on occupational exposure, symptoms development, and testing practices in the community pharmacist cohort.

Methods: Between April 30th and May 10th, a questionnaire was administered through social media to Italian community pharmacists.

Comprehensive aptamer-based screening identifies a spectrum of urinary biomarkers of lupus nephritis across ethnicities.

Emerging urinary biomarkers continue to show promise in evaluating lupus nephritis (LN). Here, we screen urine from active LN patients for 1129 proteins using an aptamer-based platform, followed by ELISA validation in two independent cohorts comprised of 127 inactive lupus, 107 active LN, 67 active non-renal lupus patients and 74 healthy controls, of three different ethnicities. Urine proteins that best distinguish active LN from inactive disease are ALCAM, PF-4, properdin, and VCAM-1 among African-Americans, sE-selectin, VCAM-1, BFL-1 and Hemopexin among Caucasians, and ALCAM, VCAM-1, TFPI and PF-4 among Asians.

Association of Urine sCD163 With Proliferative Lupus Nephritis, Fibrinoid Necrosis, Cellular Crescents and Intrarenal M2 Macrophages.

CD163 is a marker for alternatively activated macrophages, which have been implicated in the pathogenesis of lupus nephritis (LN). In our preliminary screening of urine proteins in LN, urine soluble CD163 (sCD163) was significantly elevated in patients with active LN. To evaluate the potential of sCD163 as a biomarker in LN, urine sCD163 was assayed in patients with active LN, active non-renal lupus patients (ANR), inactive SLE and healthy controls (HC), using ELISA and normalized to urine creatinine.

Alanine aminotransferase and spleno-portal dynamics affect spleen stiffness measured by point shear-wave elastography in patients with chronic hepatitis C in the absence of significant liver fibrosis.

Background: Spleen stiffness (SS) has gained a lot of interest in the context of liver cirrhosis and portal hypertension stratification. However, there is a paucity of data on confounding factors that may alter SS values.

Methods: Between January 2018 and October 2019, we enrolled 120 healthy subjects and 117 patients with hepatitis C virus (HCV) infection who did not have significant liver fibrosis (i.

Material And Methods: This retrospective analysis was conducted over a period of 7 years from 2006 to 2012. All children diagnosed with GSD on liver biopsy were included in the study.

The Importance of Transaminases Flare in Liver Elastography: Characterization of the Probability of Liver Fibrosis Overestimation by Hepatitis C Virus-Induced Cytolysis.

Background: Liver stiffness measurement (LSM) is crucial for appropriate fibrosis staging in patients with ongoing hepatitis C virus (HCV) infection. However, there is still an ongoing debate on the impact of serum transaminases (aspartate-aminotransferase, AST; alanine-aminotransferase, ALT) on LSM.

Methods: We selected 110 patients undergoing HCV eradication therapy with LSM compatible with significant liver fibrosis.

Hepatocellular carcinoma prediction beyond year 5 of oral therapy in a large cohort of Caucasian patients with chronic hepatitis B.

Background & Aims: Hepatocellular carcinoma (HCC) may develop in patients with chronic hepatitis (CHB) even after 5 years of oral therapy and cannot be easily predicted. We assessed predictors of HCC development and the need for HCC surveillance in this setting.

Methods: Of 1,951 adult Caucasians with CHB included in the PAGE-B cohort, 1,427 (73%) had completed >5 years of follow-up under therapy without developing HCC by year 5.

Number needed to treat with ursodeoxycholic acid therapy to prevent liver transplantation or death in primary biliary cholangitis.

Objective: The clinical benefit of ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) has never been reported in absolute measures. The aim of this study was to assess the number needed to treat (NNT) with UDCA to prevent liver transplantation (LT) or death among patients with PBC.

Methods: The NNT was calculated based on the untreated LT-free survival and HR of UDCA with respect to LT or death as derived from inverse probability of treatment weighting-adjusted Cox proportional hazard analyses within the Global PBC Study Group database.

Asian consensus recommendations on optimizing the diagnosis and initiation of treatment of hepatitis B virus infection in resource-limited settings.

Asia has an intermediate-to-high prevalence of and high morbidity and mortality from hepatitis B virus (HBV) infection. Optimization of diagnosis and initiation of treatment is one of the crucial strategies for lowering disease burden in this region. Therefore, a panel of 24 experts from 10 Asian countries convened, and reviewed the literature, to develop consensus guidance on diagnosis and initiation of treatment of HBV infection in resource-limited Asian settings.

miR551b Regulates Colorectal Cancer Progression by Targeting the ZEB1 Signaling Axis.

Our current understanding of the role of microRNA 551b (miR551b) in the progression of colorectal cancer (CRC) remains limited. Here, studies using both ectopic expression of miR551b and miR551b mimics revealed that miR551b exerts a tumor suppressive effect in CRC cells. Specifically, miR551b was significantly downregulated in both patient-derived CRC tissues and CRC cell lines compared to normal tissues and non-cancer cell lines.

Choosing Wisely Canada-Top Five List in Hepatology: Official Position Statement of the Canadian Association for the Study of the Liver (CASL) and Choosing Wisely Canada (CWC).

Introduction And Aim: The prevalence and incidence of chronic liver disease is increasing resulting, in substantial direct and indirect medical costs. Overuse of investigations, treatments and procedures contribute to rising health care costs and can expose patients to unnecessary harm and delay in receiving care. The Choosing Wisely Canada (CWC) campaign has encouraged professional societies to develop statements that are directly actionable by their members in an effort to promote higher-value health care that will lead to downstream effect on how other practitioners make decisions.

Ursodeoxycholic acid therapy and liver transplant-free survival in patients with primary biliary cholangitis.

Background & Aims: The clinical efficacy of ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) remains subject to debate as definitive randomized controlled trials are lacking. We aimed to determine whether UDCA prolongs liver transplant (LT)-free survival in patients with PBC.

Methods: This international cohort study included patients from the Global PBC Study Group database, originating from 8 countries in Europe and North America.

Role of Autophagy in Chronic Liver Inflammation and Fibrosis.

Autophagy entails the removal of dysfunctional components to maintain cellular homeostasis. Over the years, studies of autophagy demonstrated its complex physiological and pathological roles in the liver. Apart from regulation of normal metabolic functions such as glycogenolysis, glycogenesis, and β-oxidation, autophagy also contributes to the modulation of various liver diseases.

Genome-wide Association Study Identifies Genetic Variants Associated With Early and Sustained Response to (Pegylated) Interferon in Chronic Hepatitis B Patients: The GIANT-B Study.

Background: (Pegylated) Interferon ([Peg]IFN) therapy leads to response in a minority of chronic hepatitis B (CHB) patients. Host genetic determinants of response are therefore in demand.

Methods: In this genome-wide association study (GWAS), CHB patients, treated with (Peg)IFN for at least 12 weeks ± nucleos(t)ide analogues within randomized trials or as standard of care, were recruited at 21 centers from Europe, Asia, and North America.
