Cirrosis hepática alcohólica: actualización epidemiológica de la tasa de mortalidad entre los años 2017-2021 en Chile / Alcoholic liver cirrhosis: epidemiological update of mortality rates between 2017-2021 in Chile

Introducción: La cirrosis hepática alcohólica (CHA) es una etapa final de la enfermedad hepática por alcohol. Dada la falta de análisis epidemiológicos recientes en Chile, el objetivo de este estudio es comparar descriptivamente la tasa de mortalidad (TM) por CHA entre los años 2017-2021 en Chile. Metodología: Estudio observacional y transversal, sobre defunciones por CHA en Chile durante 2017-2021 según sexo y edad (n=2.551). Datos obtenidos del Departamento de Estadística e Información en Salud. Se utilizó estadística descriptiva y cálculo de TM. No requirió aprobación del comité de ética. Resultados: Se obtuvo una TM para el período estudiado de 3,98/100.000 habitantes. El sexo masculino presenta la mayor TM con 7,05. El grupo etario de 65-79 años presenta la mayor TM con 9,08/100.000 habitantes. Para TM por región, lidera Los Lagos con 39,84/100.000 habitantes, la menor es Coquimbo con 10,03/100.000 habitantes. Discusión: La mayor TM por CHA se encuentra en hombres, lo cual puede deberse a un mayor consumo social. El grupo etario de 65-79 años presentó la mayor TM, coincidiendo con estadísticas internacionales. El porcentaje de ruralidad pudiera afectar el consumo de alcohol, aumentando la TM por CHA en aquellas más rurales. La prevención es vital para evitar el desarrollo de CHA, siendo crucial establecer programas de salud pública para evitar el consumo de alcohol en Chile. Se identificó una falta de datos epidemiológicos en Chile, por lo que se invita a la actualización de estos.

Introduction: Alcoholic liver cirrhosis (ALC) is one of the final stages of alcoholic-related liver disease (ARLD). Due to the lack of recent epidemiological research in Chile, the main objective of this study is to descriptively compare the mortality rate (MR) due to ALC between the years 2017-2021 in Chile. Methodology: Observational and cross-sectional study, on the number of deaths owing to ALC in Chile during 20172021 according to sex and age (n=2,551). Data obtained from the department of statistics and health information. Descriptive statistics and MR calculation were used. Ethics committee approval was not required. Results: A MR was obtained for the studied period of 3.98/100,000 inhabitants. The male sex submitted the highest MR with 7.05. The age group of 65-79 years presents the highest MR with 9,08/100,000 inhabitants. The region with the highest MR is Los Lagos with 39,84/100.000 inhabitants and the one with the lowest is Coquimbo with 10,03/100.000 inhabitants. Discussion: The highest MR is found in men, which may be due the fact that, socially, men consume more alcohol than women. The age group of 65-79 years presented the highest MR, which coincides with the international statistics. The percentage of rurality impacts the alcohol consumption increasing the MR due to ALD in the most rural areas. Prevention is vital to avoid its development, so it's crucial to establish public health programs to avoid alcohol consumption in Chile. A lack of updated epidemiological information has been identified in our country, therefore it is invited to update the epidemiological data.

Evaluating Surveillance for Excessive Alcohol Use in New Mexico.

PURPOSE AND OBJECTIVES: Prevalence of excessive alcohol use and alcohol-attributable mortality is much higher in New Mexico than in other US states. In 2010, excessive alcohol use cost the state roughly $2.2 billion. Moreover, age-adjusted deaths from alcohol-related chronic liver disease increased 52.5% from 14.1 cases in 2010 to 21.5 cases in 2016. In 2017, the New Mexico Department of Health piloted the Recommended Council of State and Territorial Epidemiologists (CSTE) Surveillance Indicators for Substance Abuse and Mental Health, using 5 indicators to monitor alcohol use and health consequences. The purpose of this study is to evaluate the alcohol surveillance system implemented in New Mexico to ensure that the system yields useful, timely data that can help create effective public health interventions and that resources required for surveillance are adequate. INTERVENTION APPROACH: CSTE alcohol surveillance system data come from existing national and state-based surveys and vital statistics. EVALUATION METHODS: This evaluation assessed attributes defined in Evaluating Behavioral Health Surveillance Systems and Centers for Disease Control and Prevention guidelines for evaluating public health surveillance systems. Assessment was informed through data collection, systematic literature review searches, and an interview with the alcohol epidemiologist at New Mexico Department of Health. RESULTS: The CSTE alcohol surveillance system in New Mexico is a useful, stable, and accepted system with good representativeness and population coverage. Data sharing and collaboration between centers within New Mexico Department of Health are well-established, making data access easy and timely. Lastly, the resources required for data collection are accountable and adequate. IMPLICATIONS FOR PUBLIC HEALTH: The CSTE alcohol surveillance system brings together information (alcohol consumption behaviors and associated morbidity, mortality, and policy-related measures) necessary to show a clear picture of the alcohol effects in New Mexico. This information yields useable, timely data from which the state can monitor trends and develop interventions to reduce the prevalence of alcohol-attributable morbidity and mortality.

Alcohol Consumption Influences Clinical Outcome in Patients Admitted to a Referral Center for Liver Disease.

INTRODUCTION AND AIM: Excessive alcohol consumption is a public health concern worldwide and has been associated with high mortality rates. This study aimed to determine the prevalence of alcohol consumption and its influence on the prognosis of hospitalized cirrhotic patients in a tertiary care hospital. MATERIAL AND METHODS: We reviewed the medical records of all patients with hepatic cirrosis admitted between January 2009 and December 2014, in a referral center for liver disease in southern Brazil. Data on clinical outcomes, associated conditions, infections, and mortality were collected and compared between alcoholic and nonalcoholic patients. RESULTS: The sample consisted of 388 patients; 259 (66.7%) were men. One hundred fifty-two (39.2%) were classified as heavy use of alcohol. Most alcoholic patients were men (n = 144; 94.7%). Mean age was 55.6 ± 8.9 years. Hepatic decompensations and infections were more prevalent in alcoholic patient. Spontaneous bacterial peritonitis and respiratory tract infection accounted for most of the infections. Excessive alcohol consumption was associated with mortality (P = 0.009) in multivariate analysis. CONCLUSION: On the present study, the prevalence of heavy use of alcohol was high and associated with a poorer prognosis in hospitalized cirrhotic patients, increasing the risk of infection and death.

Burden of Chronic Viral Hepatitis and Liver Cirrhosis in Brazil - the Brazilian Global Burden of Disease Study.

INTRODUCTION AND AIM: Data on epidemiology of liver diseases in Brazil is scarce. This study aimed to estimate the burden of chronic viral hepatitis and liver cirrhosis in the country. MATERIALS AND METHODS: The indicator used was disability-adjusted life year (DALY), a sum of years of life lost due to premature mortality (YLL) and years lived with disability (YLD). Liver cirrhosis was analyzed in etiologic categories and cirrhosis of viral origin was considered part of the burden of chronic hepatitis. RESULTS: There were 57,380 DALYs (30.3 per 100,000 inhabitants) attributable to chronic hepatitis B and cirrhosis due to hepatitis B, with 41,262 DALYs in men. Most burden was caused by YLL (47,015 or 24.8/100,000) rather than YLD (10,365 or 5.5/100,000). Chronic hepatitis C and cirrhosis due to hepatitis C were responsible for 207,747 DALYs (109.6/100,000), of which 137,922 were YLL (72.7/100,000) and 69,825 (36.8/100,000) were YLD, with a higher proportion of DALYs in men (73.9%). Cirrhosis due to alcohol or other causes had a total of 536,169 DALYs (1,4% of total DALYs in Brazil), with 418,272 YLL (341,140 in men) and 117,897 YLD (97,965 in men). Highest DALYs' rates occurred at ages 60-69 in chronic hepatitis and at ages 45-59 in cirrhosis due to alcohol or other causes. CONCLUSION: Chronic viral hepatitis and liver cirrhosis are responsible for a significant burden in Brazil, affecting mainly men and individuals still in their productive years. Most burden is related to non-viral causes of cirrhosis, with a major contribution of alcohol.

Functional Capacity, Respiratory Muscle Strength, and Oxygen Consumption Predict Mortality in Patients with Cirrhosis.

Introduction. Liver diseases influence musculoskeletal functions and may negatively affect the exercise capacity of patients with cirrhosis. Aim. To test the relationship between the six-minute walk test (6MWT), maximal inspiratory pressure (MIP), and exercise capacity (VO2peak) measures and the survival rate of patients with cirrhosis. Methods. This prospective cohort study consisted of 86 patients diagnosed with cirrhosis with the following aetiology: hepatitis C virus (HCV), hepatitis B virus (HBV), and/or alcoholic cirrhosis (AC). All patients were followed up for three years and submitted to the 6MWT, pressure measurements with a compound gauge, and an exercise test (VO2peak). Results. The survival analysis showed that the individuals who covered a distance shorter than 410 m during the 6MWT had a survival rate of 55% compared with a rate of 97% for the individuals who walked more than 410 m (p = 0.0001). Individuals with MIPs below -70 cmH2O had a survival rate of 62% compared with a rate of 93% for those with MIPs above -70 cmH2O (p = 0.0001). The patients with values below 17 mL/kg had a survival rate of 55% compared with a rate of 94% for those with values above 17 mL/kg (p = 0.0001). Conclusion. The 6MWT distance, MIP, and oxygen consumption are predictors of mortality in patients with cirrhosis.

Biliary Complications After Liver Transplantation: Incidence, Risk Factors and Impact on Patient and Graft Survival.

INTRODUCTION: Biliary complications (BC) are one of the most frequent surgical complications after liver transplantation. They include biliary stenosis, leaks, choledocolitiasis and sphincter of Oddi dysfunction. These complications can cause graft dysfunction, retrasplantation, or even death. The purpose of this study was to identify factors related to BC. MATERIALS AND METHODS: The medical records of all adult patients who underwent their first liver transplantation in our institution from 2005 to 2013 were reviewed, and any BC that required management was recorded. Cumulative incidence of BC was estimated using Kaplan-Meier. Patient and graft survival was compared using the log-rank test. The Cox regression model was used to establish associated factors. RESULTS: Of the 236 patients who underwent liver transplantation, 41 patients (17.8%) developed BC. Cumulative incidence was 12.9%, 17.2%, and 20%, after 1, 3 and 5 years of the transplantation, respectively. Twenty-six cases of biliary stenosis, 11 of leaks, and 4 of choledocolitiasis were identified. Most patients were managed endoscopically (82.9%). There were no differences in patient or graft survival. DISCUSSION: Biliary stenosis is the most frequent BC. Patients with higher risk of BC were of blood type AB (P < .001), had viral hepatitis (P = .049), or had alcoholic cirrhosis (P = .036). The success with the endoscopic treatment reduced the need for surgical interventions. CONCLUSIONS: The incidence of BC in our institution is comparable with the incidence reported in other institutions. Further prospective studies with larger series of patients are warranted to identify other factors associated with development of BC.

Patients with cirrhosis in the ED: early predictors of infection and mortality.

BACKGROUND: Patients with cirrhosis have high risk of bacterial infections and cirrhosis decompensation, resulting in admission to emergency department (ED). However, there are no criteria developed in the ED to identify patients with cirrhosis with bacterial infection and with high mortality risk. STUDY OBJECTIVE: The objective of the study is to identify variables from ED arrival associated with bacterial infections and inhospital mortality. METHODS: This is a retrospective single-center study using a tertiary hospital's database to identify consecutive ED patients with decompensated cirrhosis. Clinical variables and laboratory results were obtained by chart review. Logistic regression models were built to determine variables independently associated with bacterial infection and mortality. Scores using these variables were designed. RESULTS: One hundred forty-nine patients were enrolled, most of them males (77.9%) with alcoholic cirrhosis (53%) and advanced liver disease (Child-Pugh C, 47.2%). Bacterial infections were diagnosed in 72 patients (48.3%), and 36 (24.2%) died during hospital stay. Variables independently associated with bacterial infection were lymphocytes less than or equal to 900/mm(3) (odds ratio [OR], 3.85 [95% confidence interval {CI}, 1.47-10]; P = .006) and C-reactive protein greater than 59.4 mg/L (OR, 5.05 [95% CI, 1.93-13.2]; P = .001). Variables independently associated with mortality were creatinine greater than 1.5 mg/dL (OR, 4.35 [95% CI, 1.87-10.1]; P = .001) and international normalized ratio greater than 1.65 (OR, 3.71 [95% CI, 1.6-8.61]; P = .002). Scores designed to predict bacterial infection and mortality (Mortality in Cirrhosis Emergency Department Score) had an area under the receiver operating characteristic curve of 0.82 and 0.801, respectively. The Mortality in Cirrhosis Emergency Department Score performed better than Model for End-Stage Liver Disease score. CONCLUSIONS: In this cohort of ED patients with decompensated cirrhosis, lymphopenia and elevated C-reactive protein were related to bacterial infections, and elevated creatinine and international normalized ratio were related to mortality. Scores built with these variables should be prospectively validated.

Usefulness of a new prognostic index for alcoholic hepatitis.

BACKGROUND: Alcoholic liver disease is a major cause of end-stage liver disease worldwide and severe forms of alcoholic hepatitis are associated with a high short-term mortality. Objectives To analyze the importance of age-bilirubin-INR-creatinine (ABIC) score as an index of mortality and predictor for complications in patients with alcoholic hepatitis. To evaluate its correlation with those complications, with risk of death, as well as the scores model for end stage liver disease (MELD) and Maddrey's discriminat function. METHODS: A total of 46 medical records of patients who had been hospitalized with alcoholic hepatitis were assessed retrospectively with lab tests on admission and after seven days. Score calculations were carried out and analyzed as well. RESULTS: The scores showed positive reciprocal correlation and were associated with both hepatic encephalopathy and ascites. ABIC index, which was classified as high risk, presented as a risk factor for these complications and for death. In univariate logistic regression analysis of mortality, the ABIC index at hospital admission odds ratio was 19.27, whereas after 7 days, it was 41.29. The average survival of patients with ABIC of low and intermediate risk was 61.1 days, and for those with high risk, 26.2 days. CONCLUSIONS: ABIC index is a predictor factor for complications such as ascites and hepatic encephalopathy, as well as for risk of death. Thus, it is a useful tool for clinical practice.

In-hospital mortality risk factors in patients with ascites due to cirrhosis.

INTRODUCTION: ascites is one of the most common complications of cirrhosis associated with a high rate of mortality. Although several scores have been developed in order to assess the prognosis of the disease, they were designed for predicting liver transplantation requirements and mortality in the short term, but not while in hospital. The aim of this study was to weigh risk factors for in-hospital mortality in adult patients with ascites due to alcoholic cirrhosis. MATERIAL AND METHODS: we performed a cross-sectional study in 180 adult patients with diagnosis of cirrhosis with portal hypertension associated with high alcohol intake. The diagnosis of cirrhosis was made by liver echography and portal hypertension was defined by clinical features plus serum-ascites albumin gradient. Sampled individuals were subjected to complete clinical examination. Child Pugh and the MELD scores were applied in all the patients. RESULTS: nineteen patients died while in-hospital. Mortality was associated with increased levels of serum white blood cell, urea, creatinine, prolonged prothrombin time, aspartate aminotransferase and alanine aminotransferase. We conducted a multiple binary logistic to predict in-hospital mortality which yielded that serum urea, creatinine and prothrombin time made a significant contribution to prediction with an OR 14 (95% CI 12.8 - 16.7 p = 0.03), 2 (95% CI 0.5 - 3.47, p = 0.04), and 2 (95% CI 1.03 - 2.31, p = 0.01) linearly-related. CONCLUSIONS: our results suggest that acute renal failure and prolonged prothrombin time are predictors of in-hospital mortality in patients with portal hypertension due to alcoholic cirrhosis.

Objetivos Avaliar a importância do índice age-bilirrubin-INR-creatinine (ABIC) como fator prognóstico na hepatite alcoólica e sua correlação com as complicações dessa doença, com o risco de óbito e com os escores Model for End stage Liver Disease (MELD) e Função Discriminante de Maddrey. Métodos Um total de 46 prontuários de pacientes internados por hepatite alcoólica foram avaliados de forma retrospectiva. Foi realizado levantamento de exames laboratoriais do primeiro dia de internação e 7 dias após, além de cálculo dos escores estudados. Resultados Os índices ABIC, Maddrey e MELD apresentaram correlação positiva entre si e associaram-se a encefalopatia hepática e a ascite (P<0,05). O índice ABIC, classificado de alto risco, foi fator de risco para essas complicações e para óbito. Em análise de regressão logística univariada para óbito, a razão de risco do ABIC de entrada no hospital foi de 19,27 (P=0,012) e após 7 dias de 41,29 (P=0,002). A sobrevida acumulada daqueles com ABIC de alto risco foi de 93,3% em 7 dias e de apenas 26,9% em 60 dias. Conclusões O índice prognóstico ABIC é fator de predição para complicações como ascite e encefalopatia hepática, assim como para risco de óbito, sendo ferramenta útil na prática clínica. .

In-hospital mortality risk factors in patients with ascites due to cirrhosis / Fatores de risco de mortalidade intra-hospitalar em pacientes com ascite por cirrose hepática

Introdução: ascite é uma das complicações mais comuns de cirrose associadas a uma elevada taxa de mortalidade. Embora vários escores tenham sido desenvolvidos a fim de avaliar o prognóstico da doença, eles foram concebidos para prever requisitos de transplante de fígado e mortalidade a curto prazo, mas não durante a internação. O objetivo deste estudo foi o de pesar fatores de risco para a mortalidade intra-hospitalar em pacientes adultos com ascite decorrente de cirrose alcoólica. Material e métodos: foi realizado um estudo transversal em 180 pacientes adultos com diagnóstico de cirrose com hipertensão portal, associada à alta ingestão de álcool. O diagnóstico de cirrose foi feita por ecografia hepática e a hipertensão portal foi determinada por características clínicas e pelo gradiente de albumina soro-ascite. Indivíduos avaliados foram submetidos a exame clínico completo. A classificação de Child-Pugh e a escala MELD foram aplicadas em todos os pacientes. Resultados: dezenove pacientes morreram durante a internação. A mortalidade foi associada ao aumento dos níveis de glóbulos brancos, ureia, creatinina, aspartato aminotransferase, alanina aminotransferase e tempo de protrombina prolongado. Realizamos uma logística binária múltipla para prever a mortalidade intra-hospitalar, que confirmou que ureia, creatinina e tempo de protrombina contribuíram significativamente para a previsão, com uma OR = 14 (IC 95% 12,8-16,7 p = 0,03), 2 (IC 95% 0,5-3,47, p = 0,04), e 2 (IC 95% 1,03-2,31, p = 0,01), relacionada linearmente. Conclusões: nossos resultados sugerem que a insuficiência renal aguda e de tempo de protrombina prolongado são preditores de mortalidade intra-hospitalar em pacientes com hipertensão portal decorrente de cirrose alcoólica. .

Long-term mortality of patients submitted to Roux-en-Y gastric bypass in Public Health System: high prevalence of alcoholic cirrhosis and suicides.

BACKGROUND: Bariatric surgery is a valuable therapeutic option to severe obesity. Many researches have assessed the procedure efficiency on weight reduction, improvement in comorbidities and reduction of mortality. However, studies of late mortality and its causes are still necessary, mainly in the Brazilian population. AIM: To assess late mortality, discriminating causes of death and its association with pre-operative characteristics in a series of patients submitted to bariatric surgery. METHODS: Data analyses of 248 patients submitted to Roux-en-Y gastric bypass through Public Health System, from one up to 12 years of follow-up. The analyzed variables were: gender, age by the time of the surgery, pre-operative body mass index, comorbidities and smoking. The information about mortality was obtained through the Mortality Information System. The deaths were categorized according to International Classification of Diseases 10 and statistics analysis was done through the software STATA TM 9.2. RESULTS: There were nine deaths, five of them were female. The mean age of the patients who died was 48.3 ± 8.4 years and the pre-operative body mass index was 56.0 ± 7.4 kg/m². The causes of death were: alcoholic cirrhosis (n=2), suicide (n=2), infectious causes (n=2), respiratory insufficiency (n=1), agranulocytosis (n=1) and unknown causes (n=1). None of the deaths was directly related to the surgery and there was no association of the pre-operative characteristics in mortality. CONCLUSION: There was not any association between late mortality and pre-operative characteristics. The high frequency of suicide and alcoholic cirrhosis mortality indicates the strict follow-up concerns, with appropriate psychological support to the patients.

Mortalidade no pós-operatório tardio da derivação gástrica em pacientes do Sistema Único de Saúde: elevada frequência de cirrose alcoólica e suicídios / Long-term mortality of patients submitted to Roux-en-Y gastric bypass in Public Health System: high prevalence of alcoholic cirrhosis and suicides

RACIONAL: A cirurgia bariátrica é uma opção terapêutica valiosa para tratamento de casos graves de obesidade. Sua utilização em larga escala motivou a realização de diversas pesquisas que comprovaram a eficiência do procedimento na redução do peso corporal, melhora das comorbidades e redução da mortalidade em curto e médio prazo. Entretanto, são necessários mais estudos a respeito da mortalidade de médio e longo prazo e suas causas, principalmente na população brasileira. OBJETIVO: Avaliar a mortalidade após período mínimo de um ano da operação bariátrica discriminando as causas de óbito e sua relação com características pré-operatórias. MÉTODOS: Foram analisados os dados de 248 pacientes do Sistema Único de Saúde, com seguimento entre um e 12 anos, submetidos à derivação gástrica em Y-de-Roux. As variáveis analisadas foram: sexo, idade na operação, índice de massa corporal pré-operatório, presença de comorbidades e tabagismo. As informações sobre mortalidade foram obtidas através do Sistema de Informações sobre Mortalidade. Os óbitos foram categorizados segundo o Código Internacional de Doenças 10 e a análise estatística feita através do programa STATA TM 9.2. RESULTADOS: Ocorreram nove óbitos tardios, sendo cinco de mulheres. A média de idade dos pacientes que faleceram foi 48,3±8,4 anos e o índice de massa corporal pré-operatório foi 56,0±7,4 kg/m². As causas de óbito foram cirrose alcoólica (n=2), suicídios (n=2), causas infecciosas (n=2), insuficiência respiratória (n=1), agranulocitose (n=1) e causa desconhecida (n=1). Nenhum óbito teve relação direta com o procedimento cirúrgico e não houve influência das características pré-operatórias avaliadas na mortalidade. CONCLUSÃO: Não houve relação entre a mortalidade e as características pré-operatórias. A alta frequência de mortalidade por suicídio e por complicações do alcoolismo indica a necessidade de seguimento clínico mais rigoroso, envolvendo adequado apoio psicológico aos pacientes.

[Anemia in hospitalized patients with cirrhosis: prevalence, clinical relevance and predictive factors]. / Anemia en pacientes internados con cirrosis: prevalencia, significación clínica y factores predictivos.

BACKGROUND: few studies have examined the anemia in hospitalized cirrhotic patients. OBJECTIVE: to assess the prevalence, predictive factors and prognosis for mortality of anemia in admitted cirrhotic patients. PATIENTS AND METHODS: descriptive study of cases and controls; 178 hospitalization of 114 patients were reviewed (mean age 52.4 years; 106 alcoholics) between May/2004 and June/2007. Those with acute losses of blood were excluded. The anemia was classified as slight, moderate, and severe, since a hemoglobin < 12 g/dl. There were considered as cases the admissions in which the hemoglobin had < 10 g/dl (moderate and severe anemia). RESULTS: a diagnosis of anemia was made in 155 admissions, 47% were moderate and 19% severe. Hospital mortality rate in cases was 19.6%, and in controls 5.3%, [OR 4.39 (p = 0.004)]. The independent predictive factors for mortality were: score of Child-Pügh [OR 1.99 (p = 0.0005)], creatinine > 1.5 mg/dl [OR 11.34 (p = 0.0006)] and infections [OR 5.78 (p = 0.018)]. The cases had a greater risk of renal insufficiency [27.5% vs. 3.9%, OR 9.2 (p = 0.0001)]. Classification of Child-Pügh, total bilirubin > 10 mg/dl, albumin < 2.5 g/dl, infections, hepatic encephalopathy and alcoholic hepatitis also were predictive factors of moderate-severe anemia. The independent predictive factors for moderate-severe anemia were score ofChild-Piigh and renal insufficiency. CONCLUSION: the anemia had a high prevalence with an increase of hospital mortality rate, although it was not an independent risk factor for death. The renal insufficiency and the severity of the hepatic disease were associated in independent form with moderate-severe anemia in patients admitted with cirrhosis.

[Prognostic value of plasmatic fibronectin and Child-Pugh classification in alcoholic cirrhotic patients. A comparative study]. / Valor prognóstico da fibronectina plasmática e da classifição de Child-Pugh na cirrose hepática alcoólica. Estudo comparativo.

BACKGROUND: To assess the prognostic value of plasmatic fibronectin (FN), compared to numeric Child-Pugh classification and its biochemical parameters in patients with alcoholic cirrhosis followed prospectively during a 18 months-period. METHODS: Fifty patients with the diagnosis of cirrhosis by hepatic biopsy or clinical and biochemical criteria, were included in the study after the exclusion of hepatocarcinoma and GI bleeding, infection or continous alcohol ingestion in the last 30 days. The mean age was 51.3+/-12.6 years, being 72% males and 17 of them were classified as Child-Pugh A, 18 as B and 15 as C. Serum bilirubin concentration was measured in autoanalyzer, protein electrophoresis was performed on cellulose acetate and prothrombin time by the Quick test. Plasmatic FN was assessed by radial immunodiffusion with anti-human FN in 1% agarose gel slabs. RESULTS: One patient was excluded because no natural death and 12 died owing to hepatic disease. The numeric Child-Pugh [score > 10, Relative Risk (RR)=11.33] and total bilirubins (> 2.5 mg/dL, RR=9.47) were the best predictors of death. Mean plasmatic FN concentration was significantly higher among those who survived when compared with those who died (185+/-66 mg/L x 131+/-38 mg/L, p<0.01), with a RR=6.59, for FN < 165 mg/L. Higher levels of FN, on the other hand, were the best variable to predict survival, since 96% of these 29 patients were alive at the end of follow-up. CONCLUSION: Although having less accuracy in predicting the risk of death of these patients, plasmatic FN > 165 mg/L was better predictor of survival than Child-Pugh score or any one of its biochemical parameters.

Valor prognóstico da fibronectina plasmática e da classificação de Child-Pugh na cirrose hepática alcoólica: estudo comparativo / Prognostic value of plasmatic fibronectin and Child-Pugh classification in alcoholic cirrhotic patients: a comparative study

OBJETIVOS: Avaliar o valor prognóstico da fibronectina plasmática (FN), comparativamente à classificação numérica de Child-Pugh e os parâmetros bioquímicos que a compõem, no acompanhamento prospectivo de portadores de cirrose alcoólica durante 18 meses. MÉTODOS: Incluídos 50 pacientes com cirrose alcoólica, diagnosticada por biópsia ou critérios clínico-bioquímicos, excluídos aqueles com hepatocarcinoma ou hemorragia digestiva, infecção ou ingestão alcoólica continuada nos últimos 30 dias. A idade média do grupo foi 51,3±12,6 anos, 72 por cento deles do sexo masculino e classificados 17 como Child-Pugh A, 18 como B e 15 como C. Os valores das bilirrubinas foram dosados pelo método automatizado, eletroforese de proteínas em acetato de celulose e o tempo de protrombina pelo método de Quick. A FN plasmática foi dosada por imunodifusão radial, com anticorpos contra FN humana em géis de agarose a 1 por cento. RESULTADOS: Um paciente foi excluído por óbito de causa não natural e 12 foram a óbito por doença hepática. Os melhores preditores de óbito foram a pontuação de Child-Pugh [escore>10, risco relativo (RR) de 11,33) e os valores de bilirrubina (>2,5mg/dL, RR=9,47). A concentração de FN foi significantemente maior nos sobreviventes que naqueles que foram a óbito (185±66 mg/L x 131±38mg/L, p<0,01), com RR = 6,59 para FN<165mg/L. Valores de FN acima desse valor de corte, entretanto, foram os melhores indicadores de sobrevida desde que 96,5 por cento desses 29 pacientes estavam vivos ao final de 18 meses de seguimento. CONCLUSAO: Embora apresente menor acurácia em predizer o risco de óbito desses pacientes, valores de FN plasmática> 165mg/L foram melhores indicadores de sobrevida que a classificação de Child-Pugh e seus parâmetros bioquímicos isolados.

[Outcome of liver transplantation in patients with alcoholic liver disease]. / Resultados do transplante de fígado na doença hepática alcoólica.

BACKGROUND: Liver transplantation is accepted as effective therapeutic option for end-stage liver disease, including alcoholic liver disease AIM: To evaluate the outcome of liver transplantation for alcoholic liver disease in the Liver Transplantation Program at "Hospital de Clínicas" of the Federal University of Paraná, Curitiba, PR, Brazil. PATIENTS AND METHODS: It was performed a retrospective study of the patients who underwent liver transplantation for alcoholic end-stage liver disease between September 1991 and January 2001. The minimum abstinence period required was 6 months before liver transplantation. Identification of alcohol consumption after liver transplantation was determinated by information provided by patient or family and biochemical or histological anormalities. RESULTS: Twenty patients underwent liver transplantation for alcoholic liver disease in the study period, 95% (19/20) were men and the median age was 50 years (29-61 years). Seventy-five percent of the patients (15/20) had severe liver disfunction (Child C class) in the pre-transplant period. In six of them (30%) there was association with viral hepatitis and in one, with hepatocarcinoma. Median abstinence period before liver transplantation was 24 months, varying from 9 to 120 months. One-year and 3-year survival rate were 75% and 50%, respectively. The main complications were: acute cellular rejection (40%), chronic rejection (5%), hepatic artery thrombosis (15%), biliary complications (15%), bacterial or fungal infections (45%), cytomegalovirus infection (20%). Three patients returned to alcohol use after liver transplantation CONCLUSION: The survival of patients who received liver transplant for alcoholic cirrhosis are satisfactory. In the present study there was a small index of alcohol use after liver transplantation.

The critical dimension of ethnicity in liver cirrhosis mortality statistics.

BACKGROUND: In 1997, liver cirrhosis was the 10th leading cause of death in the United States. Beginning in the 1950s, liver cirrhosis mortality rates have been consistently higher for black than for white men and women. There has been a gradual adoption of the recommendation that all death certificates include information on the Hispanic origin of decedents, with universal adoption in the 1997 data year. It is the purpose of this study to examine the extent to which relative risks for cirrhosis mortality might shift for different demographic groups when Hispanic origin is considered along with the race and sex of the decedent. METHODS: Age-adjusted death rates were calculated for liver cirrhosis by using public-use data files produced by the National Center for Health Statistics. Trends in cirrhosis mortality rates from 1991 through 1997 are shown for white Hispanic, white non-Hispanic, black Hispanic, and black non-Hispanic men and women. RESULTS: In 1997, white Hispanic men show the highest cirrhosis mortality rates over the period examined, followed by black non-Hispanic and white non-Hispanic men, white Hispanic women, and black non-Hispanic and white non-Hispanic women. Among Hispanic decedents, the largest group was of Mexican ancestry, with large numbers being born outside the United States and having low education levels. CONCLUSIONS: The findings of higher risk for cirrhosis mortality among white men and women of Hispanic origin serve to focus new attention on these demographic groups. Collateral analyses of other causes of death do not support alternate explanations of these findings as artifacts of demographic misclassification. Future studies of amounts and patterns of alcohol consumption should include Hispanic origin among demographic factors examined.

[Ecological correlation between consumption of alcoholic beverages and liver cirrhosis mortality in Mexico]. / Correlación ecológica entre consumo de bebidas alcohólicas y mortalidad por cirrosis hepática en México.

OBJECTIVE: To determine the correlation between alcohol consumption and mortality from liver cirrhosis in Mexico. MATERIAL AND METHODS: Analysis of the ecological correlation between the patterns of alcohol consumption determined by the National Addiction Survey in 1993 and mortality by liver cirrhosis, in the period between 1971-1993, in the eight regions in which the country was divided. To determine level of correlation, the Pearson and Spearman coefficients were calculated. RESULTS: Significant correlations were only found with the prevalence of spirits and pulque drinkers; with beer drinkers the correlation was negative. CONCLUSIONS: The correlation with pulque is interesting, since pulque consumption is considered to be low scale in some rural areas. The negative correlation with beer may indicate that beer drinking is nor a good indicator of alcoholism. Results, though limited to the possibilities of an ecological study, reveal the necessity of effective actions in the regions where spirits and pulque are consumed in excess.

Prognostic value of hepatic venous pressure gradient measurements in alcoholic cirrhosis: a 10-year prospective study.

BACKGROUND & AIMS: Different parameters are considered predictors of bleeding and death in alcoholic cirrhosis. The aim of this study was to establish the prognostic value of a prospective and sequential evaluation of portal pressure, variceal size, and Pugh's score in portal-hypertensive patients with alcoholic cirrhosis but no previous bleeding. METHODS: Thirty patients were evaluated for 42 +/- 5 months (median, 39 months). After baseline studies, 30 patients underwent an additional evaluation (follow-up 1; median, 10 months), 20 patients a second evaluation (follow-up 2; median, 25 months), and 13 patients a third evaluation (follow-up 3; median, 45 months). No prophylactic treatment for bleeding was given. End points were bleeding and/or death. RESULTS: Seventeen patients died, and 10 patients bled. At follow-up 1, portal pressure decreased both in survivors and nonbleeders (from 18.7 +/- 1.0 to 15.2 +/- 1.3 mm Hg [P < 0.01] and from 18.9 +/- 0.8 to 16.5 +/- 1.0 mm Hg [P < 0.05], respectively). On multivariate analysis (Cox model), portal pressure at follow-up 1 had the best prognostic and independent value for both bleeding and survival. Subsequent studies showed similar trends. CONCLUSIONS: Measurements of portal pressure provide unique prognostic information for predicting portal hypertensive-related bleeding and mortality in patients with alcoholic cirrhosis.
