RESUMO

This final report of the Lancet Commission into liver disease in the UK stresses the continuing increase in burden of liver disease from excess alcohol consumption and obesity, with high levels of hospital admissions which are worsening in deprived areas. Only with comprehensive food and alcohol strategies based on fiscal and regulatory measures (including a minimum unit price for alcohol, the alcohol duty escalator, and an extension of the sugar levy on food content) can the disease burden be curtailed. Following introduction of minimum unit pricing in Scotland, alcohol sales fell by 3%, with the greatest effect on heavy drinkers of low-cost alcohol products. We also discuss the major contribution of obesity and alcohol to the ten most common cancers as well as measures outlined by the departing Chief Medical Officer to combat rising levels of obesity-the highest of any country in the west. Mortality of severely ill patients with liver disease in district general hospitals is unacceptably high, indicating the need to develop a masterplan for improving hospital care. We propose a plan based around specialist hospital centres that are linked to district general hospitals by operational delivery networks. This plan has received strong backing from the British Association for Study of the Liver and British Society of Gastroenterology, but is held up at NHS England. The value of so-called day-case care bundles to reduce high hospital readmission rates with greater care in the community is described, along with examples of locally derived schemes for the early detection of disease and, in particular, schemes to allow general practitioners to refer patients directly for elastography assessment. New funding arrangements for general practitioners will be required if these proposals are to be taken up more widely around the country. Understanding of the harm to health from lifestyle causes among the general population is low, with a poor knowledge of alcohol consumption and dietary guidelines. The Lancet Commission has serious doubts about whether the initiatives described in the Prevention Green Paper, with the onus placed on the individual based on the use of information technology and the latest in behavioural science, will be effective. We call for greater coordination between official and non-official bodies that have highlighted the unacceptable disease burden from liver disease in England in order to present a single, strong voice to the higher echelons of government.

RESUMO

This report presents further evidence on the escalating alcohol consumption in the UK and the burden of liver disease associated with this major risk factor, as well as the effects on hospital and primary care. We reiterate the need for fiscal regulation by the UK Government if overall alcohol consumption is to be reduced sufficiently to improve health outcomes. We also draw attention to the effects of drastic cuts in public services for alcohol treatment, the repeated failures of voluntary agreements with the drinks industry, and the influence of the industry through its lobbying activities. We continue to press for reintroduction of the alcohol duty escalator, which was highly effective during the 5 years it was in place, and the introduction of minimum unit pricing in England, targeted at the heaviest drinkers. Results from the introduction of minimum unit pricing in Scotland, with results from Wales to follow, are likely to seriously expose the weakness of England's position. The increasing prevalence of obesity-related liver disease, the rising number of people diagnosed with type 2 diabetes and its complications, and increasing number of cases of end-stage liver disease and primary liver cancers from non-alcoholic fatty liver disease make apparent the need for an obesity strategy for adults. We also discuss the important effects of obesity and alcohol on disease progression, and the increased risk of the ten most common cancers (including breast and colon cancers). A new in-depth analysis of the UK National Health Service (NHS) and total societal costs shows the extraordinarily large expenditures that could be saved or redeployed elsewhere in the NHS. Excellent results have been reported for new antiviral drugs for hepatitis C virus infection, making elimination of chronic infection a real possibility ahead of the WHO 2030 target. However, the extent of unidentified cases remains a problem, and will also apply when new curative drugs for hepatitis B virus become available. We also describe efforts to improve standards of hospital care for liver disease with better understanding of current service deficiencies and a new accreditation process for hospitals providing liver services. New commissioning arrangements for primary and community care represent progress, in terms of effective screening of high-risk subjects and the early detection of liver disease.

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.

RESUMO

The Asia-Pacific region contains more than half of the world's population and is markedly heterogeneous in relation to income levels and the provision of public and private health services. For low-income countries, the major health priorities are child and maternal health. In contrast, priorities for high-income countries include vascular disease, cancer, diabetes, dementia, and mental health disorders as well as chronic inflammatory disorders such as hepatitis B and hepatitis C. Cost-effectiveness analyses are methods for assessing the gains in health relative to the costs of different health interventions. Methods for measuring health outcomes include years of life saved (or lost), quality-adjusted life years, and disability-adjusted life years. The incremental cost-effectiveness ratio measures the cost (usually in US dollars) per life year saved, quality-adjusted life year gained, or disability-adjusted life year averted of one intervention relative to another. In low-income countries, approximately 50% of infant deaths (< 5 years) are caused by gastroenteritis, the major pathogen being rotavirus infection. Rotavirus vaccines appear to be cost-effective but, thus far, have not been widely adopted. In contrast, infant vaccination for hepatitis B is promoted in most countries with a striking reduction in the prevalence of infection in vaccinated individuals. Cost-effectiveness analyses have also been applied to newer and more expensive drugs for hepatitis B and C and to government-sponsored programs for the early detection of hepatocellular, gastric, and colorectal cancer. Most of these studies reveal that newer drugs and surveillance programs for cancer are only marginally cost-effective in the setting of a high-income country.

RESUMO

Liver cirrhosis is responsible for more than 1 million deaths annually and the majority of these deaths are preventable. There is marked geographical variation in rates of mortality due to cirrhosis, and this variation in liver disease burden exemplifies the links between population risks for liver disease and mortality. The differing geographical distribution of the major risks factors for the development of liver disease including alcohol consumption, hepatitis C virus (HCV) infection, hepatitis B virus infection, and obesity and the metabolic syndrome has the potential to highlight opportunities for intervention, while the evolution of these risk factors provides insights into understanding the future burden of liver disease. This review focuses on the use of population data to identify high-risk areas and populations that would benefit from preventative interventions to reduce the mortality from liver disease. Specific strategies that are effective at the policy and public health levels are discussed to illustrate the impact these can have if widely implemented. The impact of therapies that have the potential to change the natural history of liver disease, including direct acting antivirals for HCV infection is also described. Finally, the challenges of describing the epidemiology of non-alcoholic fatty liver disease are highlighted to illustrate the need to understand the natural history of disease to inform and influence the development of novel therapies.

RESUMO

PURPOSE: Alcoholic liver disease or non-alcoholic fatty liver disease/non-alcoholic steatohepatitis are well-known risk factors for liver fibrosis or cirrhosis and hepatocellular carcinoma; it is a major global health concern, but there are few effective and safe management options. Therefore, we aimed to investigate the effects of fermented garlic extracts (FGEs) on hepatic function in adults with mild hepatic dysfunction without underlying hepatic disease. METHODS: In this double-blind, randomized, placebo-controlled study, seventy-five adults with elevated serum gamma-glutamyl transpeptidase (GGT) levels were included in a FGE-administered group (n = 36) or a placebo group (n = 39), and received either two sachets/day containing FGEs or placebo over a 12-week period. Primary endpoint was the change in serum GGT levels. Data were analysed using a generalized linear mixed effects model. RESULTS: Significant group × time interactions for serum levels of GGT (F = 3.98, P = 0.022) and alanine aminotransferase (ALT; F = 3.28, P = 0.043) were observed with an improvement in levels of GGT (P = 0.066) and ALT (P = 0.014) in the FGE group compared to that reported for the placebo group at the 12-week visits. There was no intergroup difference in the prevalence of adverse events. CONCLUSIONS: Intake of FGEs improved serum GGT and ALT levels in adults with mildly elevated serum GGT level without reported adverse side effects. FGEs might be effective and safe management options for mild hepatic dysfunction.

RESUMO

BACKGROUND: Hepatitis C (HCV), hepatitis B (HBV), alcohol-related liver disease (ALD), and non-alcohol-related fatty liver disease (NAFLD) are leading indications for adult liver transplantation in Australia and New Zealand. However, these diseases are potentially preventable through effective primary and/or secondary prevention strategies. This study evaluates the relative contribution of potentially preventable liver diseases to liver transplant numbers in Australia and New Zealand over time. METHODS: Prospectively recorded clinical, demographic, and outcome data were collected from the Australian and New Zealand Liver Transplant Registry for all primary adult liver transplants performed in Australia and New Zealand from 1 January 1985 until 31 December 2012. Potentially preventable liver disease was defined as HBV, HCV, NAFLD, ALD, and HCC. The etiology of liver disease leading to liver transplantation and the proportion of preventable liver disease-related liver transplantation was compared between Era 1 (1985-1993), Era 2 (1994-2003), and Era 3 (2004-2012). RESULTS: Overall, 1252 of 3266 adult primary liver transplants (38.3%) were performed for potentially preventable liver disease. There was a significant increase in the proportion of liver transplants because of preventable liver disease from 21.2% (93 of 439) in Era 1, to 49.8% (623 of 1252) in Era 2 and 63.5% (1000 of 1575) in Era 3 (P < 0.0001). Over time, there was a significant increase in HCV (P < 0.0001), ALD (P = 0.002), and NAFLD (P < 0.0001) as a primary indication for adult liver transplant, whereas HBV has significantly decreased from Era 1 to Era 3 as an indication for transplant (P < 0.0001). The number of transplants performed for HCC also increased across Eras (P < 0.0001), with 84% due to underlying potentially preventable liver disease. CONCLUSION: Since 2004, the majority of primary adult liver transplants within Australia and New Zealand have been because of potentially preventable liver diseases and the prevalence of these diseases has increased over time. This finding represents an opportunity for clinicians to make a significant impact on the overall burden of advanced liver disease in Australia and New Zealand by improving primary and secondary prevention measures.

RESUMO

OBJECTIVES: To explore knowledge, attitudes, behaviors, and barriers to care among patients with chronic liver disease (CLD). METHODS: Three separate, one-time-only, 60-minutes focus group sessions were audio-recorded, transcribed, and analyzed using an editing style of analysis. RESULTS: In total, 13 focus group participants provided 254 discrete comments. Emerging themes included: negative lifestyles/behaviors, lack of CLD knowledge, negative attitudes/emotions, stigma and negativity, health insurance, inaccessible/high cost medical care, drug/alcohol abuse, and discriminately sharing CLD diagnoses. CONCLUSIONS: Participants felt lack of CLD knowledge was a key factor in how patients perceived prevention, risks, causes, and treatment. These findings contribute to the important, yet limited, base of knowledge about CLD and provide a benchmark for future, more extensive studies and interventions.

RESUMO

Despite a high prevalence of liver disease in Viet Nam, there has been no nationwide approach to the disease and no systematic screening of at-risk individuals. Risk factors include chronic hepatitis B (estimated prevalence of 12%), chronic hepatitis C (at least 2% prevalence), and heavy consumption of alcohol among men. This combination of factors has resulted in liver cancer being the most common cause of cancer death in Viet Nam. There is a general lack of understanding by both the general public and health-care providers about the major risk to health that liver disease represents. We report here the initial steps taken as part of a comprehensive approach to liver disease that will ultimately include nationwide education for health-care providers, health educators, and the public; expansion of nationwide screening for hepatitis B and C followed by hepatitis B virus vaccination or treatment of chronic hepatitis B and/or hepatitis C; education about alcoholic liver disease; long-term surveillance for liver cancer; reduction of infection transmission related to medical, commercial, and personal re-use of contaminated needles, syringes, sharp instruments, razors, and inadequately sterilized medical equipment; and ongoing collection and analysis of data about the prevalence of all forms of liver disease and the results of the expanded screening, vaccination, and treatment programs. We report the beginning results of our pilot hepatitis B screening program. We believe that this comprehensive nationwide approach could substantially reduce the morbidity and mortality from liver disease and greatly lessen the burden in terms of both lives lost and health-care costs.

RESUMO

Hepatitis B virus (HBV) infection remains a major public health problem in Vietnam. Recent studies have found that prevalence of current HBV infection (HBsAg+) ranges from 10% to 20% in the general population and 20% to 40% among injecting drug users and HIV+ patients. However, HBV prevention and control in Vietnam relies heavily on universal infant vaccination program and HBsAg screening for blood donors. Currently, HBV prevention and control is underfunded by the government and receives little support from international agencies. HBV-related liver disease will continue to create a heavy burden for public health in Vietnam in the next several decades unless appropriate interventions are undertaken urgently. Establishment of a national strategy for HBV prevention and control is crucial to develop and implement effective interventions.

RESUMO

Los grandes avances realizados en la biomedicina y biotecnología durante la última década han puesto en escenamétodos rápidos e incruentos que desafían el ôgold standardõ de los procedimientos diagnósticos y terapéuticos invasivos. Algunos ejemplos de esto incluyen estudioscomo la angiografía coronaria mediante tomografía computada (TC), la resonancia magnética cardíaca (RMcardíaca) para la evaluación no invasiva de las miocardiopatías, y la colonoscopia virtual mediante TC.De esta forma, varios grupos de investigación han desarrolladométodos de imágenes para evaluar la elasticidad de los tejidos de manera no invasiva, teniendo en cuenta las propiedades mecánicas de estos. La elastografía transicional (TE) fue el primer método utilizado, hace unosocho años, en pacientes con enfermedad hepática crónica.Muchos estudios han evaluado la eficacia de este método para el diagnóstico de la fibrosis hepática y la cirrosis, y el Fibroscan es ahora una herramienta utilizada por hepatólogos de todo el mundo, teniendo en cuenta que el pronóstico y tratamiento de las enfermedades crónicas del hígado dependen en gran medida de la extensión y progresión de la fibrosis.

RESUMO

The present study evaluated the possible protective role of Livina (a polyherbal preparation) against anti-tubercular therapy (ATT)-induced liver dysfunction in patients of pulmonary tuberculosis. Patients were given intensive phase treatment with 4-drugs (rifampicin, INH, pyrazinamide and ethambutol) used for anti-tubercular therapy for 2 months, followed by a 4-month continuous phase treatment with 2 drugs (rifampicin and INH) under clinical advice and supervision. Both qualitative and quantitative measures of liver function were assessed, at different time intervals, before and after ATT. Analysis of data showed that the incidence of qualitative manifestations of liver dysfunction were greater in the placebo treated group as compared to the test drug group. None of the patients of either group showed clinical jaundice. Most signific changes ant were observed in the SGOT and SGPT levels in the placebo group, wherein the levels of both enzymes were higher at 4 and 8 weeks post-ATT, as compared to the respective baseline (0 week) values. When Livina (2 capsules twice daily) was given with ATT drugs, incidence of qualitative manifestation of liver dysfunction was insignificant and SGOT and SGPT levels were also significantly lower than the placebo+AITT drugs treated group. These results indicate that the test drug (Livina) was efficacious, against ATT-induced hepatic dysfunction in patients of pulmonary tuberculosis.

RESUMO

IMPORTANCE OF THE FIELD: Alpha-1-antitrypsin (A1AT) deficiency is a common genetic condition that predisposes individuals to the development of chronic obstructive pulmonary disease (COPD) as a direct result of damage caused to the lung by proteolytic enzymes released by migrating neutrophils. The lack of A1AT fails to control these enzymes and in the most common genetic deficiency (Pi Z) is due to accumulation of A1AT in the liver as a result of polymer formation. There is no specific treatment for COPD but understanding the pathophysiology of the disease in A1AT deficiency has led to strategies being used or developed to prevent the lung and liver disease. These strategies may have benefits beyond A1AT deficiency. AREAS COVERED IN THIS REVIEW: The review covers the history of discovery of the nature and role of A1AT deficiency with particular emphasis on the pathophysiology of the lung disease. Evidence for the role of current therapies is provided together with data of preliminary or experimental strategies that are under development. WHAT THE READER WILL GAIN: The reader will gain insight into the role of proteinases in the pathophysiology of COPD with particular reference to A1AT deficiency, which is the only human model of the disease. Current evidence of the efficacy of augmentation is provided together with new ways of readdressing the balance between neutrophil proteinases and natural or synthetic inhibitors or repairing lung damage. TAKE HOME MESSAGE: A1AT deficiency is a good model to investigate the role of inflammation and proteolytic enzymes in the pathophysiology of COPD. Augmentation therapy is expensive but restores the deficiency to normal and current evidence suggests this ameliorates progression of the disease. Understanding the mechanisms involved has led to the development of newer strategies to protect the lung and liver from the development of disease but efficacy and safety concerns require careful introduction of these strategies. Although the condition is relatively common in the Northern hemisphere, the ability to deliver conventional Phase III clinical trials with lung physiology as the primary outcome will be limited by the sensitivity of the tests and number of patients required.

RESUMO

The management of the child with intestinal failure is complex, and it is developing into a multispecialty field of its own led by expert teams of both transplant and nontransplant surgeons, gastroenterologists, and dieticians. Patients are at risk for medical, surgical, and nutritional complications that should be anticipated so that they can be prevented or managed appropriately. Catheter associated infections and intestinal failure associated liver diseases are important complications that impact the likelihood of bowel adaptation and long-term survival. The clinical assessment of a pediatric intestinal failure patient should include evaluation of the child within the context of recognized prognostic factors.
