Alterações mínimas em enzimas hepáticas à admissão hospitalar correlacionam-se à gravidade da COVID-19 em uma grande coorte no Brasil / Minimal liver enzymes abnormalities at admission are related to severe covid-19 clinical course in a large brazilian cohort

ABSTRACT Background: COVID-19 is a multisystemic disease, primarily affecting the respiratory system. Liver involvement is frequent, but the impact on the clinical course and outcomes are controversial. Objective: The aim was to assess liver function at the admission and evaluate its effects on severity and mortality in hospitalized patients with COVID-19. Methods: This is a retrospective study of hospitalized patients in a tertiary hospital in Brazil, with a PCR-confirmed SARS-CoV-2 infection between April and October 2020. 1080 out of 1229 patients had liver enzymes on admission and were divided in two cohorts, based on the presence or absence of abnormal liver enzymes (ALE). Demographic, clinical, laboratory, imaging, clinical severity, and mortality were evaluated. Patients were followed until discharge, death or transfer to another institution. Results: Median age was 60 years and 51.5% were male. The more frequent comorbidities were hypertension (51.2%), and diabetes (31.6%). Chronic liver disease and cirrhosis were present in 8.6% and 2.3%, respectively. ALE (aminotransferases higher than 40 IU/L) were present in 56.9% of patients [mild (1-2 times): 63.9%; moderate (2-5 times): 29.8%; severe (>5 times): 6.3%]. Male gender [RR 1.49, P=0.007], increased total bilirubin [RR 1.18, P<0.001] and chronic liver disease [RR 1.47, P=0.015] were predictors of abnormal aminotransferases on admission. Patients with ALE had a higher risk of disease severity [RR 1.19; P=0.004]. There was no association among ALE and mortality. Conclusion: ALE is common in COVID-19 hospitalized patients and were independently correlated with severe COVID-19. Even mild ALE at admission may be a severity prognostic marker.

RESUMO Contexto: COVID-19 é uma doença sistêmica que afeta primariamente o sistema respiratório. O comprometimento hepático é frequente, mas seu impacto no curso clínico da doença ainda é controverso. Objetivo: Avaliar na admissão hospitalar a função hepática de pacientes com COVID-19 e correlacioná-la à gravidade e mortalidade da doença. Métodos: Estudo retrospectivo de pacientes admitidos a um hospital terciário no Brasil, com infecção confirmada por SARS-CoV-2 entre abril e outubro de 2020. A coorte foi dividida em pacientes com enzimas normais ou alterada, e avaliados dados demográficos, clínicos, laboratoriais e de imagem, bem como a gravidade clínica e a mortalidade. Os pacientes foram seguidos até a alta ou óbito. Resultados: 1080 de 1229 pacientes tiveram enzimas hepáticas na admissão. A mediana de idade foi de 60 anos e 51,5% eram homens. As comorbidades mais comuns foram hipertensão (51,2%) e diabetes mellitus (31,6%). Doença hepática crônica ou cirrose estiveram presentes em 8,6% e 2,3%, respectivamente. Enzimas normais ou alterada (aminotransferases >40 IU/L) esteve presente em 56,9% [leve (1-2 vezes o normal): 63,9%; moderada (2-5 vezes): 29,8%; acentuada (>5 vezes): 6,3%]. Homens [RR 1,49; P=0,007], bilirubina total elevada [RR 1,18; P<0,001] e doença hepática crônica [RR 1,47, P=0,015] foram preditores de enzimas normais ou alterada na admissão. Pacientes com enzimas normais ou alterada tiveram maior risco de COVID-19 grave [RR 1,19; P=0,004]. Não houve associação entre enzimas normais ou alterada e mortalidade. Conclusão: Enzimas normais ou alterada é comum em pacientes hospitalizados com COVID-19. Mesmo alterações mínimas correlacionam-se de forma independente com a gravidade da doença e podem ser úteis como marcador prognóstico.

Atualização das Recomendações da Sociedade Brasileira de Hepatologia para o Tratamento Sistêmico do Carcinoma Hepatocelular / Brazilian society of hepatology updated recommendations for systemic treatment of hepatocellular carcinoma

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

Prognostic factors of liver transplantation for acute-on-chronic liver failure / Fatores prognósticos de transplante hepático em "acute-on-chronic liver failure"

ABSTRACT BACKGROUND: Liver transplantation (LT) is the only treatment that can provide long-term survival for patients with acute-on-chronic liver failure (ACLF). Although several studies identify prognostic factors for patients in ACLF who do not undergo LT, there is scarce literature about prognostic factors after LT in this population. AIM: Evaluate outcomes of ACLF patients undergoing LT, studying prognostic factors related to 1-year and 90 days post-LT. METHODS: Patients with ACLF undergoing LT between January 2005 and April 2021 were included. Variables such as chronic liver failure consortium (CLIF-C) ACLF values and ACLF grades were compared with the outcomes. RESULTS: The ACLF survival of patients (n=25) post-LT at 90 days, 1, 3, 5 and 7 years, was 80, 76, 59.5, 54.1 and 54.1% versus 86.3, 79.4, 72.6, 66.5 and 61.2% for patients undergoing LT for other indications (n=344), (p=0.525). There was no statistical difference for mortality at 01 year and 90 days among patients with the three ACLF grades (ACLF-1 vs. ACLF-2 vs. ACLF-3) undergoing LT, as well as when compared to non-ACLF patients. CLIF-C ACLF score was not related to death outcomes. None of the other studied variables proved to be independent predictors of mortality at 90 days, 1 year, or overall. CONCLUSIONS: LT conferred long-term survival to most transplant patients. None of the studied variables proved to be a prognostic factor associated with post-LT survival outcomes for patients with ACLF. Additional studies are recommended to clarify the prognostic factors of post-LT survival in patients with ACLF.

RESUMO RACIONAL: O transplante hepático (TH) é o único tratamento a proporcionar sobrevida a longo prazo para pacientes com "acute-on-chronic liver failure" (ACLF). Vários estudos identificaram fatores prognósticos para pacientes em ACLF que não realizam TH, porém há poucos dados na literatura sobre fatores prognósticos nessa população transplantada. OBJETIVOS: Avaliar desfechos de pacientes ACLF submetidos a TH, e seus preditores de mortalidade. MÉTODOS: Foram avaliados pacientes em ACLF submetidos a TH entre janeiro de 2005 e abril de 2021. Variáveis como valores CLIF-C ACLF e pontuação no ACLF foram comparadas com os desfechos. RESULTADOS: A sobrevida de ACLF pós TH de pacientes (n=25) em 90 dias, 1, 3, 5 e 7 anos, foi de 80, 76, 59,5, 54,1 e 54,1% versus 86,3, 79,4, 72,6, 66,5 e 61,2% para pacientes submetidos a TH por outras indicações (n=344), (p=0,525). Não houve diferença estatística para mortalidade em 01 ano e 90 dias entre pacientes com os três graus de ACLF (ACLF-1 vs. ACLF-2 vs. ACLF-3), bem como quando comparados a pacientes não ACLF. O escore "chronic liver failure consortium" (CLIF-C) ACLF não se correlacionou com desfechos de óbito. Nenhuma das outras variáveis estudadas mostrou-se preditora independente de mortalidade em 90 dias, após um ano ou global. CONCLUSÕES: TH conferiu sobrevida em longo prazo à maioria dos pacientes transplantados, semelhante aos pacientes submetidos à TH por outras indicações. Nenhuma das variáveis estudadas mostrou-se fator prognóstico associado a desfechos de sobrevida pós-TH para pacientes com ACLF. Estudos adicionais são necessários para estabelecer fatores prognósticos pós-TH em pacientes com ACLF.

Brazilian evidence-based guideline for screening, diagnosis, treatment, and follow-up of metabolic dysfunction-associated steatotic liver disease (MASLD) in adult individuals with overweight or obesity: A joint position statement from the Brazilian Society of Endocrinology and Metabolism (SBEM), Brazilian Society of Hepatology (SBH), and Brazilian Association for the Study of Obesity and Metabolic Syndrome (Abeso)

ABSTRACT Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up, 14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusions: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.

Microbiota intestinal, prebióticos, probióticos e simbióticos em doenças gastrointestinais e hepáticas: procedimentos de reunião conjunta da Sociedade Brasileira de Hepatologia (SBH), Núcleo Brasileiro de Estudos do Helicobacter pylori e Microbiota (NBEHPM) e Federação Brasileira de Gastroenterologia (FBG) / Gut microbiota, prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases: proceedings of a joint meeting of the brazilian society of hepatology (sbh), brazilian nucleus for the study of helicobacter pylori and microbiota (nbehpm), and brazilian federation of gastroenterology (fbg)

ABSTRACT Over the last years, there is growing evidence that microorganisms are involved in the maintenance of our health and are related to various diseases, both intestinal and extraintestinal. Changes in the gut microbiota appears to be a key element in the pathogenesis of hepatic and gastrointestinal disorders, including non-alcoholic fatty liver disease, alcoholic liver disease, liver cirrhosis, inflammatory bowel disease, irritable bowel syndrome, and Clostridium difficile - associated diarrhea. In 2019, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Nucleus for the Study of Helicobacter Pylori and Microbiota (NBEHPM), and Brazilian Federation of Gastroenterology (FBG) sponsored a joint meeting on gut microbiota and the use of prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to provide practical information about this topic, addressing the latest discoveries and indicating areas for future studies.

RESUMO Nos últimos anos, um volume crescente de evidências indica que os microrganismos estão envolvidos na manutenção da saúde humana e também estão relacionados a várias doenças, tanto intestinais quanto extraintestinais. Alterações na microbiota intestinal parecem ser um elemento chave na patogênese de doenças hepáticas e gastrointestinais, incluindo doença hepática gordurosa não-alcoólica, doença hepática alcoólica, cirrose hepática, doenças inflamatórias intestinais, síndrome do intestino irritável e diarreia associada ao Clostridium difficile. Em 2019, a Sociedade Brasileira de Hepatologia (SBH) em colaboração com o Núcleo Brasileiro para Estudo do Helicobacter pylori e Microbiota (NBEHPM) e a Federação Brasileira de Gastroenterologia (FBG) realizaram um encontro exclusivamente voltado para a discussão sobre microbiota e uso de prebióticos, probióticos e simbióticos em doenças hepáticas e gastrointestinais. Este texto resume os principais pontos discutidos durante o evento, e tem a intenção de fornecer informações práticas sobre o assunto, abordando as descobertas mais recentes e indicando áreas para estudos futuros.

Clinical and epidemiological profile of HCV genotype 3 patients in southern Brazil

Introduction: Despite the emergence of new treatments for HCV genotype 3 (HCV G3), there is still a lack of data about this particular subgroup in Brazil. Our objective was to describe clinical and sociodemographic variables and treatment profile of HCV G3 Brazilian patients. Methods: This was a descriptive, retrospective study, performed in a specialized center for HCV treatment in the South Region of Brazil. Medical records of patients diagnosed with HCV G3 were reviewed to collect clinical, sociodemographic, and treatment information. Results: Participants included total of 564 patients, with a mean age of 59.3 years (SD = 10.5). Cirrhosis was present in 54.4% of patients. The most common coexisting conditions were systemic arterial hypertension (36.6%) and diabetes mellitus (30%). Regarding treatment, 25.2% of the patients were treatment-naïve and 74.8% were currently under treatment (11.6%) or had received a previous treatment (87%). The most frequent ongoing treatment was sofosbuvir + daclatasvir (± ribavirin) (87.8%). Of the 388 patients who had at least one previous treatment, 67% achieved sustained virologic response in the last treatment. Caucasian / white, non-obese, transplanted patients, those with longer time since diagnosis and with cirrhosis were more likely to receive treatment, according to multivariate analysis. Patients with hepatocellular carcinoma were 64.1% less likely to be on treatment during the study period than those without this condition; patients with chronic kidney disease were 2.91-fold more likely to have an interruption of treatment than those without this condition. Conclusion: This study describes a large sample of Brazilian patients with HCV G3. Treatment patterns were mainly influenced by the presence of HCV complications and comorbidities.(AU)

Hepatite C no sistema público de saúde brasileiro: impacto da doença / Hepatitis c in the brazilian public health care system: burden of disease

ABSTRACT BACKGROUND: Infection by hepatitis C virus is one of the leading causes of chronic hepatitis C and cause severe burden for patients, families and the health care system. OBJECTIVE: The aims of this research were to assess the severity of liver fibrosis, comorbidities and complications of hepatitis C virus; to examine health-related quality of life (HRQoL), productivity loss and resource use and costs in a sample of Brazilian chronic hepatitis C, genotype 1, patients. METHODS: This was a cross-sectional multicenter study performed in genotype-1 chronic hepatitis C patients to assess disease burden in the Brazilian public health care system between November 2014 and March 2015. Patients were submitted to a liver transient elastography (FibroScan) to assess liver fibrosis and answered an interview composed by a questionnaire specifically developed for the study and three standardized questionnaires: EQ-5D-3L, HCV-PRO and WPAI:HepC. RESULTS: There were 313 subjects enrolled, with predominance of women (50.8%), caucasian/white (55.9%) and employed individuals (39.9%). Mean age was 56 (SD=10.4) years old. Moreover, 42.8% of patients who underwent FibroScan were cirrhotic; the most frequent comorbidity was cardiovascular disease (62.6%) and the most frequent complication was esophageal varices (54.5%). The results also showed that "pain and discomfort" was the most affected HRQoL dimension (55.0% of patients reported some problems) and that the mean HCV-PRO overall score was 69.1 (SD=24.2). Regarding productivity loss, the most affected WPAI:HepC component was daily activity (23.5%) and among employed patients, presenteeism was more frequent than absenteeism (18.5% vs 6.5%). The direct medical costs in this chronic hepatitis C sample was 12,305.72USD per patient in the 2 years study period; drug treatment costs represented 95.9% of this total. CONCLUSION: This study showed that most patients are cirrhotic, present high prevalence of cardiometabolic diseases and esophageal varices, reduced HRQoL mainly in terms of pain/discomfort, and work productivity impairment, especially presenteeism. Additionally, we demonstrated that hepatitis C virus imposes an economic burden on Brazilian Health Care System and that most of this cost is due to drug treatment.

RESUMO CONTEXTO: A infecção pelo vírus da hepatite C (HCV) é uma das principais causas de hepatite C crônica e provoca implicações graves para pacientes, familiares e sistema de saúde. OBJETIVO: Os objetivos deste estudo foram: analisar a gravidade da fibrose hepática, comorbidades e complicações da hepatite C; examinar a qualidade de vida relacionada à saúde (QVRS), a perda de produtividade e o uso de recursos e custos no sistema público por pacientes brasileiros com hepatite C crônica, genótipo tipo 1. MÉTODOS: Foi realizado um estudo transversal, multicêntrico em pacientes com hepatite C crônica genótipo-1 para avaliar a carga da doença no sistema público de saúde brasileiro entre novembro de 2014 e março de 2015. Os pacientes foram submetidos a uma elastografia hepática transitória (FibroScan) para avaliar a fibrose e a uma entrevista composta por um questionário desenvolvido para o estudo e cinco questionários padronizados: EQ-5D-3L, HCV-PRO, e WPAI:HepC. RESULTADOS: Foram recrutados 313 pacientes. A amostra foi composta predominantemente por mulheres (50,8%), caucasianos/brancos (55,9%) e indivíduos empregados (39,9%). A média de idade foi 56 (DP=10,4) anos. Em média, os pacientes com HCV esperaram 40,6 (DP=49,6) meses entre o diagnóstico e o primeiro tratamento. Ademais, 42,8% dos pacientes que realizaram o FibroScan tinham cirrose; a comorbidade mais frequente foi doença cardiovascular (62,6%) e a complicação mais comum as varizes esofágicas (54,5%). Os resultados também mostraram que "dor e desconforto" foi a dimensão de QVRS mais afetada (55,0% dos pacientes relataram alguns problemas) e que a média do escore do HCV-PRO foi 69,1 (DP=24,2). Em relação à perda de produtividade, o componente do WPAI:HepC mais afetado foi atividade diária (23,5%) e entre os pacientes empregados, presenteísmo foi mais frequente do que absenteísmo (18,5% vs 6,5%). Os custos diretos médicos totais com essa amostra foi de 12.305,72USD por paciente em um período de dois anos; o tratamento medicamentoso representou 95% desse total. CONCLUSÃO Esse estudo mostrou a maioria dos pacientes possui cirrose, apresenta alta prevalência de doenças cardiometabolicas e varizes esofágicas, QVRS reduzida principalmente em termos de dor/desconforto e dano na produtividade, especialmente presenteísmo. Adicionalmente, nós demonstramos que o HCV impõe uma carga econômica no sistema de saúde brasileiro e que os medicamentos correspondem à maioria dos custos.

Hepcidin serum levels in HCV chronically mono-infected naïve patients, compared to healthy individuals

Introduction: Metabolism of iron is altered in patients infected with chronically Hepatitis C. The aim of this study is to compare compare the hepcidin levels in between individuais chronically infected with HCV and uninfected individuals. The aim of this study is to compare the hepcidin serum levels between individuals chronically infected with HCV and uninfected individuals. Methods: A cross-sectional study evaluating hepcidin serum levels of mono-infected HCV (n=29), naive, non-diabetic, non-cirrhotic and non-obese patients by means of ELISA, compared to uninfected patients (n=9) with the same characteristics. The degree of liver fibrosis, according to the METAVIR scale on liver biopsies, the lipid profile, the resistance insulin level, as calculated on HOMA-IR (homeostatic model assessment for insulin resistance), the interleukin-6 (IL-6) and the ferritin serum levels were also measured. Results: The levels of hepcidin were significantly lower in HCV patients compared to controls (8.4 pg/mL (±4.94) vs. 19.51 pg/mL (±5.51)) with p<0.001. The levels of ferritin and hepcidin did not show any relation. There was no difference between hepcidin levels in relation to viral genotype, viral load, IL-6 and degrees of fibrosis within HCV infected individuals. Conclusion: It is possible that hepatic iron overload in this population is explained by suppressed levels of hepcidin in patients with HCV. (AU)

Conclusão: Existem alterações nas variáveis cardiopulmonares e há associação entre o VO2MAX e a FAM em pacientes cirróticos pelo vírus da hepatite C.

ABSTRACT Introduction: Cirrhosis causes changes in gas exchange and protein-calorie malnutrition in patients with liver disease. Objective: To evaluate and compare cardiopulmonary variables, handgrip strength (HGS) and body composition between cirrhotic patients with hepatitis C virus and healthy individuals, and to correlate maximal oxygen uptake (VO2MAX) with HGS. Methods: This survey is characterized as a case-control study composed of 36 participants (18 cirrhotic patients with HCV and 18 healthy individuals) of both sexes, older than 18 years. The palmar grip strength was measured by dynamometry using a mechanical handle dynamometer with adjustable handle. The ventilatory variables were evaluated by ergospirometry with a progressive load test on a cycloergometer. The body composition was measured by a level II cineanthropometry technician. Independent t test and Mann-Whitney test were used for comparison between groups and Spearman correlation for association between variables. Results: There were differences in maximal oxygen uptake 16.20 (11.60-18.55), median and interquartile range x 19.90 (16.27-26.85), ventilation 45.40 (36.45-54.20) x 63.40 (50.40-78.00), carbon dioxide production 785.88 (655.81-963.14) x 988.04 (826.93-1546.21), maximum heart rate (127.66 ± 23.26, mean and ± SD) x (146.29 ± 23.31), first ventilatory threshold (10.700 ± 3.19) x (14.912 ± 4.45) and second ventilatory threshold (14.16 ± 4.48) x (18.25 ± 5.54) between cirrhotic patients and controls, respectively. We found a moderate positive correlation between maximal oxygen uptake and handgrip strength (r=0.474, p=0.047) Conclusion: There are changes in cardiopulmonary variables and there is an association between VO2MAX and HGS in cirrhotic patients with hepatitis C virus.

Encontramos una correlación positiva moderada entre el consumo máximo de oxígeno y la fuerza de prensión manual (r = 0,474, p = 0,047). Conclusión: Existen cambios en las variables cardiopulmonares y hay asociación entre el VO2MAX y FPM en pacientes cirróticos por el virus de la hepatitis C.

Effectiveness and safety of first-generation protease inhibitors in real-world patients with hepatitis C virus genotype 1 infection in Brazil: a multicenter study

OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients treated with Peg-interferon, ribavirin, and either boceprevir (n=158) or telaprevir (n=557) between July 2013 and April 2014 at 15 reference centers in Brazil. Demographic, clinical, virological, and adverse events data were collected during treatment and follow-up. RESULTS: Of the 715 patients, 59% had cirrhosis and 67.1% were treatment-experienced. Based on intention-to-treat analysis, the overall sustained viral response was 56.6%, with similar effectiveness in both groups (51.9% for boceprevir and 58% for telaprevir, p=0.190). Serious adverse events occurred in 44.2% of patients, and six deaths (0.8%) were recorded. Cirrhotic patients had lower sustained viral response rates than non-cirrhotic patients (46.9% vs. 70.6%, p<0.001) and a higher incidence of serious adverse events (50.7% vs. 34.8%, p<0.001). Multivariate analysis revealed that sustained viral response was associated with the absence of cirrhosis, viral recurrence after previous treatment, pretreatment platelet count greater than 100,000/mm3, and achievement of a rapid viral response. Female gender, age>65 years, diagnosis of cirrhosis, and abnormal hemoglobin levels/platelet counts prior to treatment were associated with serious adverse events. CONCLUSION: Although serious adverse events rates were higher in this infected population, sustained viral response rates were similar to those reported for other patient cohorts.

Reduced hand grip strength in overweight and obese chronic hepatitis c patients

ABSTRACT Background Hepatitis C is a liver disease that causes significant changes in metabolism, and also has an impact on nutritional status. Objective To evaluate the nutritional status and cardiovascular risk in patients with chronic hepatitis C. Methods This cross-sectional study investigated 58 patients with chronic hepatitis C, non-cirrhotic and were not under active pharmacological treatment. Patients with significant alcohol consumption (greater than 10 g ethanol/day) were excluded. Patients underwent nutritional assessment through anthropometric measurements and functional assessment using hand grip strength by dynamometry. The physical activity was assessed using the International Physical Activity Questionnaire. Patients also underwent clinical and laboratory evaluation. Cardiovascular risk was calculated by the Framingham score. Results The mean age of patients was 51.6±9.7 years, 55.2% were female, and 79.3% had genotype 1. The most prevalent degree of fibrosis was F1 (37.9%) followed by F2 (27.6%) and F3 (1.7%). The prevalence of overweight/obesity considering the body mass index was 70.7%. However, 57.7% of men and 68.8% of women were considered malnourished according to hand grip strength. These patients also had waist circumference (93.5±10.7 cm) and neck circumference (37.0±3.6 cm) high. Almost 60% of patients were considered sedentary or irregularly active. In relation to cardiovascular risk, 50% of patients had high risk of suffering a cardiovascular event within 10 years. Conclusion Although most patients with hepatitis C presented overweight, associated with high cardiovascular risk, they also have reduced functional capacity, indicative of protein-caloric commitment. Therefore, body mass index can not be considered the only method of assessment for nutritional diagnosis of patients with liver disease. Adopting methods such as hand grip strength can be important for a better understanding of nutritional status of these patients.

RESUMO Contexto A hepatite C é uma doença hepática que provoca alterações importantes no metabolismo e também tem impacto no estado nutricional. Objetivo Avaliar o estado nutricional e o risco cardiovascular em pacientes com hepatite C crônica. Métodos Este estudo transversal investigou 58 pacientes com hepatite C crônica, não cirróticos e que não estavam sob tratamento farmacológico ativo. Pacientes com consumo de álcool significativo (maior de 10 g de etanol/dia) foram excluídos. Os pacientes realizaram avaliação nutricional, através de medidas antropométricas, e avaliação funcional, através da medida da força do aperto de mão pela dinamometria. A prática de atividade física foi avaliada através do Questionário Internacional de Atividade Física. Os pacientes também passaram por avaliação clínica e laboratorial. O risco cardiovascular foi calculado pelo escore de Framingham. Resultados A média de idade dos pacientes foi 51,6±9,7 anos, 55,2% eram do sexo feminino, e 79,3% apresentavam genótipo 1. O grau de fibrose mais prevalente foi F1 (37,9%), seguido por F2 (27,6%) e F3 (1,7%). A prevalência de sobrepeso/obesidade considerando o índice de massa corporal foi de 70,7%. No entanto, 57,7% dos homens e 68,8% das mulheres foram considerados desnutridos de acordo com a força do aperto de mão. Estes pacientes também apresentaram circunferência da cintura (93,5±10,7 cm) e circunferência do pescoço (37,0±3,6 cm) elevados. Quase 60% dos pacientes foram considerados sedentários ou irregularmente ativos. Em relação ao risco cardiovascular, 50% dos pacientes apresentou elevado risco de sofrer evento cardiovascular em 10 anos. Conclusão Apesar de grande parte dos pacientes com hepatite C apresentarem excesso de peso, associado a alto risco cardiovascular, os mesmos também apresentaram diminuição da capacidade funcional, indicativa de comprometimento proteico-calórico. Portanto, o índice de massa corporal não pode ser considerado o único método de avaliação para diagnóstico nutricional de pacientes com doença hepática. Adotar métodos como a força do aperto de mão pode ser importante para uma melhor compreensão do estado nutricional destes pacientes.

Introdução: A Hepatite C tem uma prevalência estimada de cerca de 170 milhões de pessoas mundialmente e cursa com grande morbimortalidade. O tratamento deste deste vírus tem se alterado significativamente nos últimos anos, porém, no Brasil, ainda imperam os tratamentos baseados em interferon convencional ou em interferon -peguilado associado à ribavirina. Métodos: Estudo de coorte, retrospectivo, conduzido no Hospital de Clínicas de Porto Alegre. Foram incluídos 237 pacientes com Hepatite C tratados com interferon e ribavirina ou com interferon -peguilado e ribavirina. Resultados: A taxa global de resposta virológica sustentada obtida foi de 33,33%, sendo 37,93% nos pacientes com regime baseado em interferon convencional e 32,69% nos pacientes com interferon -peguilado. A análise demonstrou uma maior taxa de resposta virológica sustentada entre os pacientes que apresentaram, à análise genética, expressão CC do polimorfismo do IL 28B.

Introduction: Hepatitis C affects approximately 170 million people worldwide and it results in great morbidity and mortality. The virus treatment has changed significantly. However, in Brazil, treatments based on conventional interferon or pegylated-interferon associated with ribavirin are still the most usual ones. Methods: Retrospective cohort study conducted at Hospital de Clínicas de Porto Alegre. That included 237 patients treated for hepatitis C with interferon and ribavirin or pegylated--interferon and ribavirin. Results: The overall rate of sustained virologic response was 33.33%, with a rate of 37.93% in patients treated with conventional interferon and 32.69% in with pegylatedinterrferon. The analysis showed a higher rate of sustained virologic response among patients who, in genetic analysis, CC expression of IL28B polymorphism.

Contribution of dynamometry and the Royal Free Hospital global assessment to the nutritional assessment of patients with chronic liver diseases / Contribución de la dinamometría y la evaluación global del Royal Free Hospital en la evaluación nutricional de la enfermedad hepática crónica

Protein-calorie malnutrition (PCM) is a prognostic factor increasing complications and mortality in chronic liver diseases. Objectives: To quantify the dietary intake and compare different methods of nutritional assessment in patients with chronic liver diseases. Ninety seven outpatients of Hospital de Clínicas de Porto Alegre, with chronic hepatits (CH) and cirrhosis (CIR), were assessed from April 2009 to January 2010. The CH patients presented higher calorie and protein intake (p<0.05) than the CIR patients. Malnutrition prevalence in CH and CIR groups by the Royal Free Hospital-Global Assessment (RFH) was 51.2 vs 84%, Hand Grip Strength 61 vs 82.1%, Subjective Global Assessment 14.6 vs 32.1%, Adductor Pollices Muscle 7.3 vs 14.3%, Arm Muscle Circumference 4.9 vs 14.3% and Body Mass Index2.4 vs 3.6% (p<0.05), respectively. HGS and RFH were the best methods to identify malnutrition and present concordance with each other.

La prevalencia de desnutrición en los grupos HC y CIR fué: Royal Free Hospital-global assessment (RFH) 51,2 vs 84%, hand grip streght (HGS) 61 vs 82,1%, evaluación subjetiva global 14,6 vs 32,1%, músculo aductor del pulgar 7,3 vs 14,3%, circunferencia muscular del brazo 4,9 vs 14,3% y el indice de masa corporal 2,4 vs 3,6% (p<0,05). HFH y HGS fueron los métodos que mejor evidenciaron la malnutrición habiendo concordancia entre ellos.

Encefalopatia hepática: relatório da 1ª reunião monotemática da Sociedade Brasileira de Hepatologia / Hepatic encephalopathy: report 1st monothematic meeting of the Brazilian Society

A encefalopatia hepática (EH) é um distúrbio funcional do sistema nervoso central (SNC) associado à insufi ciência hepática, de fisiopatologia multifatorial e complexa. Devido aos avanços no conhecimento sobre o manejo da EH na cirrose e na insuficiência hepática aguda (IHA), a diretoria da Sociedade Brasileira de Hepatologia (SBH) promoveu uma reunião monotemática acerca da fi siopatologia, diagnóstico e tratamento da EH, abordando aspectos controversos relacionados ao tema. Com a utilização de sistemática da medicina baseada em evidências, foram abordados o manejo da EH e da hipertensão intracraniana na IHA, o manejo da EH episódica na cirrose, as controvérsias no manejo da EH e a abordagem da EH mínima. O objetivo desta revisão é resumir os principais tópicos discutidos na reunião monotemática e apresentar recomendações sobre o manejo da síndrome votadas pelo painel de expertos da SBH.

Hepatic encephalopathy (HE) is a functional disorder of the central nervous system (CNS) associated with liver failure, either end-stage chronic liver disease or fulminant hepatic failure. Its pathogenesis remains complex and poorly understood. In view of recent advances in the management of HE, the Brazilian Society of Hepatology endorsed a monothematic meetingregarding HE in order to gather experts in the to discuss related data and to draw evidence-based recommendations concerning: management of HE and intracranial hypertension in FHF, treatment of episodic HE in cirrhosis, controversies in the management of EH including difficult to treat cases and diagnostic and treatment challenges for minimal HE. The purpose of this review is to summarize the lectures and recommendations made by the panel of experts of the Brazilian Society of Hepatology.

Aging and its impact onthe quality of grafts: an experimental study in rats livers / O impacto do envelhecimento na qualidade do enxerto: estudo experimental em fígados de ratos

CONTEXT: There are consistent clues of worse results with grafts from older donors, especially in hepatitis C. University of Wisconsin (UW) solution is adopted for liver preservation, but other solutions are being studied, as fructose-1,6-bisphosphate (FBP). OBJECTIVE: To determinate the impact of aging of the donor on the cold ischemia injury in rat livers and compare UW and FBP. METHODS: Twenty male Wistar rats were studied - 10, aging 20 weeks: 5 to preservation with UW (C-UW) and 5, FBP (C-FBP); and other 10, aging 50 weeks: 5 to UW (E-UW) and 5 to FBP (E-FBP). Rats were anesthesized, submitted to hepatectomy, and graft was kept under 2-4ºC for 8 hours. Liquid samples were taken at 2, 4, 6, and 8 hours, to determine AST and LDH. At the end, in the liver tissue thiobarbituric acid reactive substances and catalase were determined. RESULTS: Average liver weight was similar between controls and the others (12.5 g ± 1.8 and 13.4 g ± 2.0). AST and LDH levels were higher in C-UW group (P<0.05). In the older group, there was a difference between UW and FBP preserved livers related to LDH, but not to AST. Thiobarbituric acid reactive substances were superior in control group than in the older one (P = 0.001). Catalase activity was similar between these groups (P = 0.11), but it was superior in UW preserved animals (P = 0.02). CONCLUSION: Livers from older rats were similar to the controls regarding cold ischemia injury in FBP group. Surprisingly, with UW solution there was less cold ischemia injury in the elderly group. When comparing both solutions, FBP provided significantly more protection than UW in the controls. There was a trend to FBP to being better than UW in the elderly group. Further studies with liver from older donors and ischemia and reperfusion are needed.

CONTEXTO: Dados da literatura atual sugerem piores resultados quando os transplantes hepáticos são realizados com enxertos provenientes de doadores idosos. O uso da solução Universidade de Wisconsin (UW) é universal; entretanto alternativas como a fructose-1,6-bisfosfato (FBP) vêm sendo estudadas. OBJETIVOS: Determinar o impacto do envelhecimento do doador no dano de isquemia a frio em fígados de ratos, comparando as soluções de FBP e UW. MÉTODOS: Vinte ratos Wistar foram estudados - 10 com 20 semanas: 5 preservados com UW (C-UW) e 5 com FBP (C-FBP); e outros 10, com 50 semanas: 5 com UW (E-UW) e 5 com FBP (E-FBP). A preservação durou 8 horas. Foram dosadas AST e LDH nas alíquotas do líquido de preservação a cada 2 horas. RESULTADOS: Os níveis de AST e LDH foram superiores no grupo (C-UW) (P<0.05). Quando comparadas UW x FBP no grupo de idosos houve diferença quanto à LDH, mas não com a AST. CONCLUSÃO: A preservação dos fígados de ratos idosos foi similar aos dos controles, quando preservados com FBP. Quando utilizada UW, a lesão de preservação foi menor no grupo de ratos idosos. A FBP minimizou a isquemia a frio nos controles, quando comparada a UW. Houve tendência de a FBP ser superior a UW no grupo idosos.

Prevalence of diabetes mellitus and impaired glucose tolerance in patients with decompensated cirrhosis being evaluated for liver transplantation: the utility of oral glucose tolerance test

CONTEXT: Cirrhosis, diabetes mellitus, impaired glucose tolerance, insulin resistance, and protein calorie malnutrition are important issues in cirrhotic patients because they can increase the progression of liver disease and worsen its prognosis. OBJECTIVE:To determine the prevalence of diabetes mellitus, impaired glucose tolerance and insulin resistance in cirrhotic patients being evaluated for liver transplantation and their impacts on a 3-month follow-up, and to compare fasting glycemia and oral glucose tolerance test. METHODS: A cross-sectional study was performed in consecutively included adult patients. Diabetes mellitus was established through fasting glycemia and oral glucose tolerance test in diagnosing diabetes mellitus in this population. HOMA-IR and HOMA-β indexes were calculated, and nutritional assessment was performed by subjective global assessment, anthropometry and handgrip strength through dynamometry. RESULTS: Diabetes mellitus was found in 40 patients (64.5 percent), 9 (22.5 percent) of them by fasting glycemia and 31 (77.5 percent) of them by oral glucose tolerance test. Insulin resistance was found in 40 (69 percent) of the patients. There was no relationship between diabetes mellitus and the etiology of cirrhosis. Protein calorie malnutrition was diagnosed in a range from 3.22 percent to 45.2 percent by anthropometry, 58.1 percent by subjective global assessment and 88.7 percent by handgrip strength. Diabetes mellitus identified by oral glucose tolerance test was related significantly to a higher prevalence of infectious complications and deaths in a 3-month period (P = 0.017). CONCLUSION: The prevalence of diabetes mellitus, impaired glucose tolerance, insulin resistance and protein calorie malnutrition is high in cirrhotic patients on the waiting list for liver transplantation. There were more infectious complications and/or deaths in a 3-month follow-up period in patients with diabetes mellitus diagnosed ...

CONTEXTO: Cirrose, diabetes mellitus, intolerância à glicose e resistência insulínica é uma associação que vem sendo discutida, bem como a desnutrição nesta população, pelo risco de pior evolução de hepatopatia. OBJETIVO: Determinar a prevalência de diabetes mellitus, intolerância à glicose e resistência insulínica e desnutrição protéico-calórica em cirróticos (vírus C+ ou -) candidatos a transplante hepático e avaliar a capacidade diagnóstica dos testes de diabetes mellitus e seu impacto na evolução em 3 meses. MÉTODOS: Estudo transversal prospectivo de pacientes consecutivos, com avaliação de diabetes mellitus por glicemia de jejum e/ou teste de tolerância oral à glicose, cálculo dos índices HOMA-IR e avaliação nutricional através da avaliação subjetiva global, antropometria e força do aperto de mão não-dominante. RESULTADOS: Sessenta e quatro virgula cinco por cento tinham diabetes mellitus, 9 (22,5 por cento) deles foram diagnosticados por glicemia de jejum e 31 (77,5 por cento) por tolerância oral à glicose. A resistência insulínica foi encontrada em 40 pacientes (69 por cento). Não houve relação com a causa da cirrose. A desnutrição protéico-calórica foi encontrada em 3,22 por cento dos pacientes através do índice de massa corporal, 45,2 por cento por antropometria, 58,1 por cento pela avaliação subjetiva global e 88,7 por cento pela força do aperto de mão não-dominante. Houve associação entre diabetes mellitus diagnosticado pelo teste de tolerância oral à glicose e a maior prevalência de complicações infecciosas e/ou morte em 3 meses (P = 0,017). CONCLUSÃO: A prevalência de diabetes mellitus, intolerância à glicose, resistência insulínica e desnutrição protéico-calórica é alta em cirróticos em lista de transplante hepático. A evolução em 3 meses é pior quando há diabetes mellitus. O teste de tolerância oral à glicose teve rendimento superior à glicemia de jejum no diagnóstico de diabetes mellitus. Sugere-se o emprego rotineiro ...

Some other rare anomalies has been found. Conclusion: The results of this study have demonstrated the frequency and types of anatomical variants of the hepatic artery, evidencing the importance of the recognition of these anomalies in the prevention of postoperative complications of the liver transplantation, as well as of the diverse invasive surgical and radiological procedures on the supra-mesocolic floor (AU)

Infections after liver transplantation in adults: data from a university hospital in southern Brazil (1996-2000)

BACKGROUND: Infections after liver transplantations are the most important cause of morbi-mortality. In this study, we assessed the main characteristics of these infections in a southern Brazilian university hospital. METHODS: We conducted a retrospective cohort with 55 patients who underwent orthotopic liver transplantation between 1996 and 2000 in the "Hospital de Clínicas de Porto Alegre", Porto Alegre, RS, Brazil, to characterize the infections that occurred in the group. RESULTS: One or more infections (average 2.10) were diagnosed in 47 patients, especially during the first month after transplantation. The most common were bacteremia, intra-abdominal infections and pneumonia, predominantly with bacteria, especially Staphylococcus sp (and particularly S. aureus) and E. coli. The mortality rate attributed to infections was high: 17 cases of all deaths (total 27 deaths). Significant risk factors for infections included reoperation, diabetes, biliary stenosis and higher Child-Pugh scores. CONCLUSION: Infections remain a severe threat in liver transplant patients, and special efforts should be made to prevent and manage them correctly.

RACIONAL: Infecções são a causa principal de morbimortalidade em pacientes submetidos a transplantes hepáticos. OBJETIVO: Avaliar as principais características destas infecções em pacientes de um hospital universitário do sul do Brasil. MÉTODO: Uma coorte retrospectiva foi conduzida com os 55 pacientes transplantados hepáticos adultos cuja cirurgia foi realizada entre 1996 e 2000 no Hospital de Clínicas de Porto Alegre, RS, todos aos eventos infecciosos que ocorreram nesta população foram registrados. RESULTADOS: Uma ou mais infecções (média 2,1 episódios) foram diagnosticadas em 47 pacientes, o período de maior ocorrência destas foi o primeiro mês após a cirurgia. As infecções mais comuns foram: bacteremias, infecções intra-abdominais e pneumonias, a etiologia mais freqüente foi bacteriana, sendo os germes mais comuns os estafilicocos (em particular o S. aureus) e a E. coli. A taxa de mortalidade associada a infecções foi elevada: 17 óbitos de todos observados na coorte (27 no total). Os fatores de risco para infecção estatisticamente significantes foram: reoperação, diabetes, estenose de via biliar e classificação de Child-Pugh elevada. CONCLUSÃO: As infecções continuam sendo grave ameaça aos pacientes transplantados hepáticos e intenso esforço, que envolve o conhecimento da epidemiologia microbiológica, pesquisa e acompanhamento dos pacientes deve ser empregado, para prevenir e tratar de forma adequada estas complicações.
