RESUMO

BACKGROUND: Point shear-wave elastography (pSWE) is a new method to assess the degree of liver fibrosis. It has been shown to be effective in detecting stiffness in viral hepatitis. OBJECTIVES: To determine the feasibility of pSWE for assessing liver stiffness and fibrosis in liver diseases of different etiologies. METHODS: This prospective single-center study included a population of adult patients with chronic liver diseases from different etiologies, who were scheduled for liver biopsy, and a control group of healthy adults who prospectively underwent pSWE. Ten consecutive pSWE measurements of the liver were performed using a Philips iU22 ultrasound system. Stiffness degree was compared to liver biopsy results. Fibrosis degree was staged according to METAVIR scoring system. RESULTS: The study group was comprised of 202 patients who underwent liver biopsy and pSWE test and a control group consisting of 14 healthy adults who underwent pSWE for validation. In the study group, the median stiffness was 5.35 ± 3.37 kilopascal (kPa). The median stiffness for F0-1, F2, F3, and F4 as determined by liver biopsy results were 4.9 kPa, 5.4 kPa, 5.7 kPa, and 8 kPa, respectively. The median stiffness in the control group was 3.7 ± 0.6 kPa. Subgroup analyses were conducted for viral hepatitis vs. non-viral hepatitis and steatohepatitis vs. non-steatohepatitis groups. CONCLUSIONS: pSWE is a reproducible method for assessing liver stiffness and is in a linear relationship with fibrosis degree as seen in pathology. Compared with patients with non-significant fibrosis, healthy controls showed significantly lower values.

RESUMO

Treatment of hepatitis C with direct-acting antivirals is safe and highly efficacious, resulting in viral clearance (sustained virological response [SVR]) in the vast majority of patients. Although SVR is mostly permanent and associated with a significant reduction of liver morbidity and mortality, some patients may still suffer from a major risk of progressive liver damage, potentially leading to severe complications - including liver decompensation, hepatocellular carcinoma and death. This concise review discusses some of the most important features of residual liver disease in patients with chronic hepatitis C who have achieved SVR after antiviral therapy.

RESUMO

The Polycystic Kidney Disease (PKD) is characterized by progressive renal cyst development and other extrarenal manifestation including Polycystic Liver Disease (PLD). Phenotypical characterization of animal models mimicking human diseases are commonly used, in order to, study new molecular mechanisms and identify new therapeutic approaches. The main biomarker of disease progression is total volume of kidney and liver in both human and mouse, which correlates with organ function. For this reason, the estimation of the number and area of the tissue occupied by cysts, is critical for the understanding of physiological mechanisms underlying the disease. In this regard, cystic index is a robust parameter commonly used to quantify the severity of the disease. To date, the vast majority of biomedical researchers use ImageJ as a software tool to estimate the cystic index by quantifying the cystic areas of histological images after thresholding. This tool has imitations of being inaccurate, largely due to incorrectly identifying non-cystic regions. We have developed a new software, named CystAnalyser (register by Universidade de Santiago de Compostela-USC, and Fundación Investigación Sanitaria de Santiago-FIDIS), that combines automatic image processing with a graphical user friendly interface that allows investigators to oversee and easily correct the image processing before quantification. CystAnalyser was able to generate a cystic profile including cystic index, number of cysts and cyst size. In order to test the CystAnalyser software, 795 cystic kidney, and liver histological images were analyzed. Using CystAnalyser there were no differences calculating cystic index automatically versus user input, except in specific circumstances where it was necessary for the user to distinguish between mildly cystic from non-cystic regions. The sensitivity and specificity of the number of cysts detected by the automatic quantification depends on the type of organ and cystic severity, with values 76.84-78.59% and 76.96-89.66% for the kidney and 87.29-93.80% and 63.42-86.07% for the liver. CystAnalyser, in addition, provides a new tool for estimating the number of cysts and a more specific measure of the cystic index than ImageJ. This study proposes CystAnalyser is a new robust and freely downloadable software tool for analyzing the severity of disease by quantifying histological images of cystic organs for routine biomedical research. CystAnalyser can be downloaded from https://citius.usc.es/transferencia/software/cystanalyser (for Windows and Linux) for research purposes.

RESUMO

BACKGROUND: Ventriculoperitoneal shunt is the most common treatment to manage hydrocephalus; it is unfortunately burdened by up to 25% of complications. The peritoneal approach may expose patients to many complications, however the formation of a liver pseudocyst is a rare occurrence, and its mechanisms are still largely unknown. CASE REPORT: We report the case of a 69-year-old woman with ventriculoperitoneal shunt, inserted for the management of post aneurysmal subarachnoid hemorrhage hydrocephalus, presenting to the Accident and Emergency for acute cholecystitis. Besides confirming the diagnosis, an ultrasound investigation revealed the presence of a hepatic cyst. Conservative treatment with antibiotics and non-steroidal anti-inflammatory drugs was performed with favorable outcome and resorption of the cyst. Interestingly the patient kept on presenting several similar episodes managed well by non-steroidal anti-inflammatory drugs alone, each of them associated with transient symptoms and signs of ventriculoperitoneal shunt malfunction. Computerized Tomography brain and lumbar puncture were normal, whereas CT abdomen showed the ventriculoperitoneal shunt distal catheter passing through the hepatic cyst. Given the ventriculoperitoneal shunt malfunction, in the context of an infective/inflammatory process a conversion of the ventriculoperitoneal shunt into a ventriculo-atrial shunt was carried out with successful clinical outcome. CONCLUSION: Based on current literature we propose a clinical and radiological classification of such pseudocysts related to ventriculoperitoneal shunt. Clinical presentation, diagnostic findings and management options are proposed for each type: purely infective, spurious (infective/inflammatory) and purely inflammatory. In the absence of system infection, a simple replacement of the distal catheter seems to be the best solution.

RESUMO

BACKGROUND AND AIMS: Pirfenidone (PFD), an oral antifibrotic drug, has been authorized by the EMA and FDA for treatment of idiopathic pulmonary fibrosis. Few studies have addressed its use in advanced liver fibrosis (ALF). We evaluated a prolonged-release formulation (PR-PFD) plus standard of care on disease progression in ALF. METHODS: 281 ALF patients from 12 centers receiving PR-PFD (600 mg bid) were screened; 122 completed 1 year of treatment. Additionally, 74 patients received only standard of care regimen. Average age was 64 ± 12 years, 58% female. 43.5% had fatty liver disease (NAFLD), 22.5% viral hepatitis C (VHC), 17% autoimmune hepatitis (AIH), and 17% alcoholic liver disease (ALD). Baseline fibrosis was F4 in 74% and F3 in 26%. Antifibrotic effects were assessed by transient elastography (Fibroscan®) and Fibro Test® (FT); Cytokines and PFD plasma levels were tracked and quality of life evaluated. RESULTS: We found a significant reduction in fibrosis in 35% of PR-PFD patients and only in 4.1% in non PR-PFD patients. Child-Pugh score improved in 29.7%. Biochemical values remained stable; 40.6% and 43.3% decreased ALT or AST, respectively. TGFß1 (pg/mL) levels were lower in PFD-treated patients. PFD serum concentration (µg/mL) was higher (8.2 ± 1.7) in fibrosis regression profile (FRP) patients compared to fibrosis progression profile (FPP) patients (4.7 ± 0.3 µg/mL, p < 0.01). 12% reported transient burning or nausea and 7% photosensitivity. Quality of life (Euro-Qol scale) improved from 62 ± 5 to 84 ± 3 (p < 0.001) and from 32 ± 3 to 42 ± 2 (p < 0.008) (FACIT scale). CONCLUSIONS: PR-PFD is efficacious and safe in ALF and associated with promising antifibrotic effects. TRIAL REGISTRATION: Clinical trial number: NCT04099407.

RESUMO

RESUMEN La microbiota se refiere al conjunto de todos los de microorganismos que se localizan de manera normal en distintos sitios de los cuerpos de los seres vivos pluricelulares, tales como el cuerpo humano. Las modificaciones del eje intestino-hígado se ha convertido en la actualidad en un grave problema científico al haberse encontrado en diversas investigaciones, que esta microbiota está relacionada con el daño hepático con independencia de la causa de la lesión hepática. Se realizó una revisión sistemática sobre las implicaciones demamicrobiota intestinal en las enfermedades hepáticas. Se realizó una revisión de artículos científicos publicados entre 2012 y 2018 en diversas bases de datos en línea. Se presenta el conocimiento existente hasta el momento sobre la microbiota intestinal en pacientes portadores de enfermedades hepáticas, con hincapié en las hepatitis C y la cirrosis hepática. La composición de microbiota de intestino estuvo asociada con el perfil inflamatorio y marcadores de fibrosis hepática, las que mejoraron con el tratamiento de antivirales de acción directa aunque las medidas de permeabilidad intestinal e inflamación permanecían inalteradas. Se reporta mejoría de los pacientes portadores de hepatitis viral tipo C, con antivirales de acción directa la cual estuvo asociada con modificaciones de la microbiota intestinal, que se correlacionó con mejoría en la fibrosis e inflamación hepática, los avances en este campo abren nuevas perspectivas en la biomedicina (AU).


SUMMARY Microbiota refers to the whole of microorganisms located in a normal way in different places of the bodies of pluricelular living beings, like the human body. The modifications of the axis intestine-liver have become a serious scientific problem, because in different researches researchers have found that this microbiota is related to hepatic damage depending on the cause of this hepatic lesion. To carry out a systematic review on the implication of intestinal macrobiota in liver diseases. The scientific articles published in the period 2012-2018 in different databases on line were reviewed. A total of 26 bibliographic sources were used, original articles and reviews. The authors present knowledge existent up to the moment on intestinal microbiota in patients who have liver diseases, making emphasis on hepatitis C and hepatic cirrhosis. The composition of the intestine microbiota was associated to an inflammatory and markers of hepatic fibrosis that improved with the treatment of direct action antivirals although the measures of intestinal permeability and inflammation remained inalterably. It is reported an improvement of patients carriers of viral hepatitis type C with the use direct action retrovirals, what was linked to modifications in the intestinal microbiota, and correlated to an improvement of fibrosis and liver inflammation; the advances obtained in this field open new perspectives in biomedicine (AU).

RESUMO

Extracellular vesicles are membrane-bound vesicles containing proteins, lipids, RNAs and microRNAs. They can originate from both healthy and stressed cells, and provide a snapshot of the cell of origin in physiological and pathological circumstances. Various processes that may give rise to the release of extracellular vesicles occur in liver diseases, including hepatocyte apoptosis, hepatic stellate cell activation, liver innate immune system activation, systemic inflammation, and organelle dysfunction (mitochondrial dysfunction and endoplasmic reticulum stress). Numerous studies have therefore investigated the potential role of extracellular vesicles as biomarkers in liver diseases. This review provides an overview of the methods that can be used to measure extracellular vesicle concentrations in clinical settings, ranging from plasma preparation to extracellular vesicle measurement techniques, as well as looking at the challenges of using extracellular vesicles as biomarkers. We also provide a comprehensive review of studies that test extracellular vesicles as diagnostic, severity and prognostic biomarkers in various liver diseases, including non-alcoholic and alcoholic steatohepatitis, viral hepatitis B and C infections, cirrhosis, primary liver cancers, primary sclerosing cholangitis and acute liver failure. In particular, extracellular vesicles could be useful tools to evaluate activity and fibrosis in non-alcoholic fatty liver disease, predict risk of hepatitis B virus reactivation, predict complications and mortality in cirrhosis, detect early hepatocellular carcinoma, detect malignant transformation in primary sclerosing cholangitis and predict outcomes in acute liver failure. While most studies draw on data derived from pilot studies, which still require clinical validation, some extracellular vesicle subpopulations have already been evaluated in solid prospective studies.

RESUMO

This document, written by the French Association for the Study of the Liver (AFEF) board, aims to provide information to physicians involved in the care of patients with liver disease during the Coronavirus disease (COVID-19) epidemic. These are not based on a systematic review of the literature and a rigorous evaluation using the GRADE method. These are recommendations based on feedback from China available in the form of original articles or letters - for which the scientific evidence is often modest - and the rules put forward by American (1) and European (Boettler et al, 2020) hepatology societies, the French National Digestive Cancer Thesaurus (Di Fiore et al., 2020) and the Francophone Transplantation Society (4). These suggestions require adjustment according to the geographical particularities of the epidemic, available standard procedures and access to local resources. This document will be updated as regularly as possible according to the evolution of our knowledge and characteristics on the epidemic.

RESUMO

Three types of intracytoplasmic inclusions immunoreactive to fibrinogen are collectively diagnosed as hepatic fibrinogen storage disease. This study aimed to better characterize ground glass (type II) and globular (type III) fibrinogen inclusions by the pathological examination of 3 cases and a literature review. Three adults (age: 32-64 years; male/female = 2:1) were unexpectedly found to have fibrinogen-positive ground glass changes (type II inclusions) by liver needle biopsy, against a background of acute hepatitis E, resolving acute cholangitis, or severe lobular hepatitis of unknown etiology. One patient also had fibrinogen-positive intracytoplasmic globules (type III inclusions) in the first biopsy, but they were not present in a second biopsy. None had coagulation abnormalities or hypofibrinogenemia. On immunostaining, both inclusions were strongly positive for not only fibrinogen but also C-reactive protein and C4d. Ultrastructurally, ground glass changes corresponded to membrane-bound cytoplasmic inclusions containing amorphous, granular material. The pathological features of type II fibrinogen inclusions were identical to those of pale bodies in hepatocellular carcinoma. The literature review suggested that type I fibrinogen inclusions characterized by a polygonal appearance are strongly associated with mutations in fibrinogen genes, coagulopathy, and family history, whereas type II/III inclusions are immunoreactive to multiple proteins and typically develop in cases of other unrelated liver diseases. In conclusion, type II and III fibrinogen inclusions do not represent a true hereditary storage disease but instead the collective retention of multiple proteins. Given the lack of clinical significance, a less specific name (e.g., pale body) may be more appropriate for those inclusions.

RESUMO

Cases of new pseudotumors of the liver were collected from multiple medical centers. Four resection and 4 biopsy specimens were collected, including 4 women and 4 men at an average age of 48 ± 15 years (range: 28-73 years). The lesions were visible on imaging but were either ill-defined or had indeterminate features for characterization. They ranged in size from 2 to 9 cm and were multiple in five cases. The resection specimens showed lesions that had vague borders but were visible in juxtaposition to the normal liver on gross examination. Histologically, the lesions also had ill-defined borders and were composed of benign reactive liver parenchyma. Central vein thrombi were seen in 5 cases, and portal vein thrombi, in 2 cases. These vascular changes were associated reactive parenchymal changes including sinusoidal dilation, patchy bile ductular proliferation, and portal vein abnormalities. All lesions lacked the histological findings of hepatic adenomas, focal nodular hyperplasia, or other known tumors and pseudotumors of the liver. In summary, this study provides a detailed description of a new pseudotumor of the liver: a reactive, hyperplastic mass-like lesion that forms in association with localized vascular thrombi, for which we propose the term regenerative hepatic pseudotumor. This lesion can closely mimic other benign or malignant hepatic tumors on imaging and histology.

RESUMO

PURPOSE: To evaluate the benefit of the additional available information present in spectral CT datasets, as compared to conventional CT datasets, when utilizing convolutional neural networks for fully automatic localisation and classification of liver lesions in CT images. MATERIALS AND METHODS: Conventional and spectral CT images (iodine maps, virtual monochromatic images (VMI)) were obtained from a spectral dual-layer CT system. Patient diagnosis were known from the clinical reports and classified into healthy, cyst and hypodense metastasis. In order to compare the value of spectral versus conventional datasets when being passed as input to machine learning algorithms, we implemented a weakly-supervised convolutional neural network (CNN) that learns liver lesion localisation without pixel-level ground truth annotations. Regions-of-interest are selected automatically based on the localisation results and are used to train a second CNN for liver lesion classification (healthy, cyst, hypodense metastasis). The accuracy of lesion localisation was evaluated using the Euclidian distances between the ground truth centres of mass and the predicted centres of mass. Lesion classification was evaluated by precision, recall, accuracy and F1-Score. RESULTS: Lesion localisation showed the best results for spectral information with distances of 8.22 ± 10.72 mm, 8.78 ± 15.21 mm and 8.29 ± 12.97 mm for iodine maps, 40 keV and 70 keV VMIs, respectively. With conventional data distances of 10.58 ± 17.65 mm were measured. For lesion classification, the 40 keV VMIs achieved the highest overall accuracy of 0.899 compared to 0.854 for conventional data. CONCLUSION: An enhanced localisation and classification is reported for spectral CT data, which demonstrates that combining machine-learning technology with spectral CT information may in the future improve the clinical workflow as well as the diagnostic accuracy.

RESUMO

BACKGROUND: The objective of this study was to determine the most optimal timing of liver transplant (LT) for post-Kasai portoenterostomy (KPE) patients based on disease severity scores. METHODS: This was a retrospective study and the clinical data of all LT recipients aged <18 years (n = 89) with a history of KPE were analyzed. They were divided into three groups according to their PELD/MELD scores at the time of LT (A: <15; B: 15-25; C: >25). The effects of LT on the clinical outcomes and hospitalization status were analyzed. RESULTS: There were 33, 34 and 22 patients in group A, B and C, respectively. There was no significant difference in 3-year graft survival rate between the three groups but group C patients had the highest incidence of vascular or biliary complications (p = 0.022). Group C patients had a significantly lower hospital admission frequency (p = 0.036) and shorter hospital stay (p = 0.041) after LT when compared with their pre-LT status and with non-LT patients with similar disease severity scores. On the other hand, the hospitalization frequency and duration were similar in patients with the lowest disease severity score (group A) before, after and without LT. CONCLUSIONS: The benefit of LT was less obvious when the disease severity score is <15. A high complication rate was reported when LT was performed at a score > 25. Donor availability, the patient's general condition and parental wish should be considered during individual assessment. TYPE OF STUDY: Clinical research paper. LEVEL OF EVIDENCE: Level III.

RESUMO

The US Liver Imaging Reporting and Data System (LI-RADS) was released in 2017 and is the newest of the four American College of Radiology (ACR) LI-RADS algorithms. US LI-RADS provides standardized terminology, technical recommendations, and a reporting framework for US examinations performed for screening or surveillance in patients at risk for developing hepatocellular carcinoma (HCC). The appropriate patient population for screening and surveillance includes individuals who are at risk for developing HCC but do not have known or suspected cancer. This includes patients with cirrhosis from any cause and subsets of patients with chronic hepatitis B virus infection in the absence of cirrhosis. In an HCC screening or surveillance study, US LI-RADS recommends assigning two scores that apply to the entire study: the US category, which determines follow-up, and a visualization score, which communicates the expected level of sensitivity of the examination but does not affect management. Three US categories are possible: US-1 negative, a study with no evidence of HCC; US-2 subthreshold, a study in which an observation less than 10 mm is depicted that is not definitely benign; and US-3 positive, a study in which an observation greater than or equal to 10 mm or a new thrombus in vein is identified, for which diagnostic contrast material-enhanced imaging is recommended. Three visualization scores are possible: A (no or minimal limitations), B (moderate limitations), and C (severe limitations). ©RSNA, 2019.

RESUMO

Liver diseases affect millions of people worldwide. In most developed countries, the incidence of viral hepatitis is waning as a result of modern advances in disease prevention, diagnosis, and therapies. Expanded programmes for systematic immunisation against hepatitis B virus have also significantly brought down the number of new cases in many countries, including China. In contrast, with the improvement in living standards, the prevalence of metabolic liver diseases including non-alcoholic fatty liver disease and alcohol-related liver disease is set to rise, ultimately leading to more cases of end-stage liver diseases (liver failure, cirrhosis, and liver cancer). Over the past 30 years, visionary governments of major nations have provided strong incentives for basic/clinical research, vaccination programmes, and drug discovery and development in the field of hepatology. To get rid of her unflattering title as the "leader in liver diseases", China has also made a serious effort to initiate nationwide preventive measures for liver diseases, global partnerships, and mentoring programmes for young hepatologists. Instrumental to such progress is the continuous support of the National Natural Science Foundation of China (NSFC), which has helped hepatology to thrive in virtually all research directions within the country. In this article, we seek to provide stimulating glimpses into the evolving liver disease epidemiology, institutional research profiles, funding landscape, and drug development trends in China, with an attempt to compare her status and achievements with those of the United States, European countries, and Japan.

RESUMO

BACKGROUND: In inflammatory bowel disease (IBD) patients there are reports of the occurrence of hepatobiliary manifestations, so the aim of this study was to evaluate the hepatobiliary manifestations in patients with Crohn's disease (CD) and ulcerative colitis (UC) from an IBD reference center. METHODS: Cross-sectional study in an IBD reference center, with interviews and review of medical charts, between July 2015 and August 2016. A questionnaire addressing epidemiological and clinical characteristics was used. RESULTS: We interviewed 306 patients, and the majority had UC (53.9%) and were female (61.8%). Hepatobiliary manifestations were observed in 60 (19.6%) patients with IBD. In the greater part of the patients (56.7%) hepatobiliary disorders were detected after the diagnosis of IBD. In UC (18.2%) patients, the hepatobiliary disorders identified were 11 (6.7%) non-alcoholic fatty liver disease, 9 (5.5%) cholelithiasis, 6 (3.6%) primary sclerosing cholangitis (PSC), 3 (1.8%) hepatotoxicity associated with azathioprine, 1 (0.6%) hepatitis B, and 1 (0.6%) hepatic fibrosis. In CD (21.3%) patients, 11 (7.8%) had cholelithiasis, 11 (7.8%) non-alcoholic fatty liver disease, 4 (2.8%) PSC, 3 (2.1%) hepatotoxicity, 1 (0.7%) hepatitis B, (0.7%) hepatitis C, 1 (0.7%) alcoholic liver disease, and 1 (0.7%) autoimmune hepatitis (AIH). There was one case of PSC/AIH overlap syndrome. CONCLUSION: The frequency of hepatobiliary disorders was similar in both forms of IBD in patients evaluated. The most common nonspecific hepatobiliary manifestations in IBD patients were non-alcoholic liver disease and cholelithiasis. The most common specific hepatobiliary disorder was PSC in patients with extensive UC or ileocolonic CD involvement; this was seen more frequently in male patients.

RESUMO

The intestinal microbiome plays a major role in the pathogenesis of liver disease, with a hallmark event being dysbiosis, or an imbalance of pathobionts and beneficial bacteria with the associated deleterious effects on their host. Reducing the number of intestinal bacteria with antibiotic treatment is generally advantageous in experimental liver diseases. Complete absence of intestinal microbiota as in germ-free rodents can be protective in autoimmune hepatitis and hepatic tumors induced by chemicals, or it can exacerbate disease as in acute toxic liver injury and liver fibrosis/cirrhosis. In alcoholic liver disease, nonalcoholic fatty liver disease, and autoimmune cholangiopathies, germ-free status can be associated with worsened or improved hepatic phenotype depending on the experimental model and type of rodent. Some of the unexpected outcomes can be explained by the limitations of rodents raised in a germ-free environment including a deficient immune system and an altered metabolism of lipids, cholesterol, xenobiotics/toxins, and bile acids. Given these limitations and to advance understanding of the interactions between host and intestinal microbiota, simplified model systems such as humanized gnotobiotic mice, or gnotobiotic mice monoassociated with a single bacterial strain or colonized with a defined set of microbes, are unique and useful models for investigation of liver disease in a complex ecosystem.

RESUMO

In 2005, the National Institutes of Health (NIH) chronic graft-versus-host disease (cGVHD) consensus project provided diagnosis and staging criteria, based mostly on clinical experience and expert opinion. These criteria were revised in 2014, aiming to provide enhanced specificity and clarity. However, the impact of 2014 changes to the original NIH cGVHD severity scoring criteria has not been reported. In this study, 284 patients, prospectively enrolled on the National Cancer Institute's cross-sectional cGVHD natural history study, were scored using the 2005 NIH cGVHD criteria and then rescored according to the 2014 modifications. In comparing the two criteria, 2014 cGVHD global severity scoring resulted in a tendency toward being categorized as milder scores (75 vs. 72% of severe score per 2014, p = 0.0009), with a statistically significant shift in NIH liver and lung scores toward milder categories (p < 0.0001). 2005 and 2014 NIH global severity scores showed a significant association with reduced grip strength (p < 0.0001), reduced joint range of motion (p = 0.0003), and the subspecialist evaluation score (p < 0.0001). Poor survival prediction of the severe NIH lung score is also retained in the new criteria (p = 0.0012). These findings support the use of 2014 cGVHD scoring criteria in continuous efforts to develop better classification systems.

RESUMO

BACKGROUND: Given the lack of long-term prospective studies, it is challenging for clinicians to make informed decisions about screening and treatment decisions regarding the risk of hepatocellular carcinoma (HCC) in patients with non-alcoholic steatohepatitis (NASH) who do not have cirrhosis. AIM: To characterise the pooled risk of HCC in the non-cirrhosis population. METHODS: Published studies were identified through April 2016 in MEDLINE, Scopus, Science Citation Index, AMED and the Cochrane Library. Two independent reviewers screened citations and extracted data. Random effect odds ratios (OR) were calculated to obtain aggregate estimates of effect size between NASH and non-NASH groups. Between-study variability and heterogeneity were assessed. RESULTS: Nineteen studies with 168 571 participants were included. Eighty-six per cent of included subjects had cirrhosis. The prevalence of HCC in non-cirrhotic NASH was 38.0%; among other aetiologies in non-cirrhotics, it was 14.2% (P < 0.001). Non-cirrhotic NASH subjects were at greater odds of developing HCC than non-cirrhotic subjects of other aetiologies (OR 2.61, 95% CI 1.27-5.35, P = 0.009). When examining all NASH subjects either with or without cirrhosis, those with NASH as the underlying liver disease did not have a significantly increased risk of HCC (OR 1.43, 95% CI 0.77-2.65, P = 0.250). CONCLUSIONS: In non-cirrhotic subjects, those with NASH have a higher risk of HCC compared to other aetiologies of liver disease. Further study investigating the risk factors of HCC among non-cirrhotic NASH patients is needed.

RESUMO

BACKGROUND: The objective of this study was to determine health-related quality of life (HRQoL) among chronic liver disease (CLD) subjects in South Korea using EuroQol five-dimension questionnaire (EQ-5D). METHOD: The sample consisted of 139 subjects with CLD from the sixth Korean National Health and Nutrition Examination Survey (KNHNES VI). Data were analyzed using SPSS program for descriptive statistics, t-test, ANOVA, Scheffe's test and hierarchical multiple regression. RESULTS: Results indicated that marital status (P < 0.01), occupation (P < 0.01), basic livelihood security recipient status (P < 0.05), hepatocellular carcinoma (P < 0.05), subjective health status (P < 0.01), and depression (P < 0.001) were significant predictors of HRQoL. Health behaviors (alcohol intake, sleep duration) variables were insignificant. CONCLUSION: In conclusion, marital status, occupation, basic livelihood security recipient status (BLSRS), hepatocellular carcinoma (HCC), subjective health status (SHS), and depression were confirmed to be factors affecting the HRQoL. We should be provide to continuous monitoring and education of adequate alcohol intake for patients with CLD. Findings of this study might be used to develop community based health programs and policies for CLD.

RESUMO

The burden of liver disease in Europe continues to grow. We aimed to describe the epidemiology of liver diseases and their risk factors in European countries, identifying public health interventions that could impact on these risk factors to reduce the burden of liver disease. As part of the HEPAHEALTH project we extracted information on historical and current prevalence and mortality from national and international literature and databases on liver disease in 35 countries in the World Health Organization European region, as well as historical and recent prevalence data on their main determinants; alcohol consumption, obesity and hepatitis B and C virus infections. We extracted information from peer-reviewed and grey literature to identify public health interventions targeting these risk factors. The epidemiology of liver disease is diverse, with variations in the exact composition of diseases and the trends in risk factors which drive them. Prevalence and mortality data indicate that increasing cirrhosis and liver cancer may be linked to dramatic increases in harmful alcohol consumption in Northern European countries, and viral hepatitis epidemics in Eastern and Southern European countries. Countries with historically low levels of liver disease may experience an increase in non-alcoholic fatty liver disease in the future, given the rise of obesity across most European countries. Liver disease in Europe is a serious issue, with increasing cirrhosis and liver cancer. The public health and hepatology communities are uniquely placed to implement measures aimed at reducing their causes: harmful alcohol consumption, child and adult obesity, and chronic infection with hepatitis viruses, which will in turn reduce the burden of liver disease.
