Hemorragia digestiva alta varicosa: relatório do 1º consenso da Sociedade Brasileira de Hepatologia / Varicel bleeding: consensus meeting report from the brazilian society of hepatology

Nas últimas duas décadas, foi observada redução importante na mortalidade associada ao primeiro sangramento varicoso, que vem sendo atribuída à melhoria na assistência ao paciente cirrótico e à abordagem multidisciplinar do paciente com hemorragia digestiva alta varicosa (HDAV), particularmente por emergencistas, hepatologistas, gastroenterologistas, endoscopistas e intensivistas. Visando estabelecer recomendações para o manejo da HDAV, a Sociedade Brasileira de Hepatologia (SBH) realizou reunião de consenso para elaboração de documento a ser utilizado como orientação de conduta médica. Dentro da sistemática utilizada, foi criada pela SBH uma comissão organizadora composta por quatro membros que escolheram 27 pesquisadores, representando as diversas regiões do país, para serem moderadores ou expositores dos tópicos relacionados à prevenção, diagnóstico e tratamento da HDAV. Todos os tópicos foram abordados de acordo com o grau de evidência científica disponível. As recomendações foram elaboradas em reunião após ampla discussão com os membros da comissão organizadora, expositores, moderadores e participantes da reunião do consenso, ficando a cargo da comissão organizadora a redação do documento final. A reunião do consenso ocorreu em Salvador em 06 de maio de 2009 e esta publicação exibe as principais conclusões do consenso organizadas sob a forma de resumo da literatura médica seguido pelas recomendações da SBH.

In the last decades, several improvements in the management of variceal bleeding have resulted in a significant decrease in morbidity and mortality of cirrhotis with bleeding varices. Progress in the multidisciplinary approach to the patient with variceal blleding has led to a better management of this disease by critical care physicians, hepatologists, gastroenterologists, endoscopists, radiologists and surgeons. In this respect, the Brazilian Society of Hepatology has, recently, sponsored a consensus meeting in order to draw evidence-based recommendations on the management of these difficult-totreat subjects. An organizing committee comprised of four people was elected by the Governing Board and was responsible to invite 27 researchers from distinct regions of the country to make a systematic review of the subject and to present topics related to variceal bleeding, including prevention, diagnosis, management and treatment, accoding to evidence-based medicine. After the meeting, all participants were held together for discussion of the topics and the elaboration of the aforementioned recommendations. The organizing committee was responsible for writing the final document. The meeting was held at Salvador, May 6th, 2009 and the present manucrispt is the summary of the systematic review that was presented during the meeting organized in topics followed by the reccomendations of the Brazilian Society of Hepatology.

Nonalcoholic fatty liver disease in Brazil. Clinical and histological profile.

BACKGROUND: The epidemiology and clinical characteristics of nonalcoholic fatty liver disease (NAFLD) in South America are not well known. Brazil is a largest country in this part of the world and the present study aimed to contribute with this information. METHODS: This descriptive study included patients from medical centers around Brazil, who had diagnosis of NAFLD. They were selected from chart review and also prospectively in Hepatology out-clinics. Patients with history of alcohol intake and others liver diseases were excluded. Histological diagnosis included: steatosis or steatohepatitis (steatosis, ballooning of hepatocytes or fibrosis). The criteria to perform a liver biopsy was ALT or AST > 1.5 x normal levels. RESULTS: A total of 1280 patients from 16 Brazilian centers and all five regions were included. The mean age was 49.68 ± 13.59 years; 53.3% were males and 85% were asymptomatic. Hyperlipidemia was observed in 66.8% cases, obesity in 44.7%, overweight in 44.4%, diabetes in 22.7%, and toxins exposure in 10%. Metabolic syndrome was observed in 41.3% cases. Elevated levels of ALT, AST and GGT were observed in 55.8%, 42.2% and 63.1% cases, respectively. Liver biopsy performed in 437 cases showed: isolate steatosis in 42% cases, steatohepatitis in 58% and 27% of them also presented fibrosis. Cirrhosis was observed in 15.4% and hepatocellular carcinoma in 0.7%. CONCLUSIONS: NAFLD in Brazil is more frequent in asymptomatic males; steatohepatitis with fibrosis and cirrhosis were a significant diagnosis. The genetic predisposition and lifestyle should be influenced in the spectrum; however these findings deserve a future investigation.

Etiology of hepatocellular carcinoma in Latin America: a prospective, multicenter, international study.

BACKGROUND/AIMS: No prospective study has been published investigating etiology of HCC in Latin America. The primary aim of this prospective study was to analyze the etiology of liver disease in patients with HCC from our area. Secondary aims were to evaluate staging using Okuda and BCLC classifications; and percentage of patients receiving treatment. METHODS: The Governing Board of the Latin American Association for the Study of the Liver designed the protocol. During a 18 month period, all members were invited to load their incident HCC cases on line. RESULTS: 240 cases from 9 countries were uploaded, 174 were male (72.5%), median age was 64 years, interquartile range 57-72. In 85.4% of cases, patients had underlying cirrhosis. Main etiological factors were: HCV in 74 patients (30.8%), alcohol in 49 (20.4%), cryptogenic cirrhosis in 35 (14.6%), HBV in 26 (10.8%), HCV plus alcohol in 14 (5.8%). Considering the combinations, hepatitis C was shown in 91 patients (38%); chronic alcoholism in 68 patients (28%); and hepatitis B in 33 patients (14%). There were no significant differences between the groups in the age at diagnosis. Percentage of male gender was higher in groups of alcohol (94%), HCV plus alcohol (93%) and HBV (85%) than in cryptogenic cirrhosis (60%) and HCV (59%) (p<0.001). CONCLUSIONS: Our prospective study showed that hepatitis C is the more frequent etiology of HCC in Latin America, followed by alcoholic cirrhosis. Demographical results showed a male predominance (male:female ratio 2.6) with an important proportion of patients being diagnosed at their sixties.
