Evaluation of a strategy for identification of hepatitis C virus carriers in outpatient and emergency units: contribution to the microelimination of hepatitis C in Brazil

ABSTRACT Introduction: Hepatitis C virus (HCV) infection continues to be an important public health problem worldwide. Despite the availability of drugs that promote the cure of infection in more than 95% of cases, the identification of HCV carriers remains a major challenge. Objective: To evaluate a strategy for identifying HCV carriers based on combined criteria: screening in emergency units and specialty outpatient clinics of a tertiary hospital and among older adults (≥45 years), both suggested as efficient in epidemiological studies. Methods: A cross-sectional, analytical and descriptive study was conducted on individuals of both sexes, aged 45 years and older, attending the emergency department and specialty outpatient clinics of a University Hospital in São Paulo, Brazil, from January 2016 to June 2018. After giving formal consent, the patients were submitted to a standardized interview and rapid testing for the identification of HCV antibodies (SD BIOLINE® anti-HCV). Results: A total of 606 adult patients (62% women and 37% men) were evaluated. The mean age was 62 ± 10 years. Four positive tests were identified, with confirmation by conventional serology and HCV-RNA determination. Thus, the prevalence of HCV identified in the sample was 0.66%. All patients had a history of risk factors for infection. Conclusion: The strategies of birth-cohort testing and screening in emergency medical services for the identification of HCV carries, both suggested in the literature as efficient for the diagnosis of hepatitis C, resulted in a low rate of HCV infection. These findings highlight the magnitude of the challenge of identifying asymptomatic HCV carriers in Brazil.

Practical Considerations of Real Life of Hepatocellular Carcinoma in a Tertiary Center of Brazil

ABSTRACT Background. Hepatocellular carcinoma (HCC) is the most common malignancy that develops in cirrhotic livers. Its clinical and epidemiological characteristics and mortality rates vary according to geographical region. The objective of this study was to evaluate the clinical profile, epidemiological characteristics, laboratory parameters, treatment and survival of patients with HCC. Material and methods. Patients with HCC seen between 2000 and 2012 were studied. The Kaplan-Meier method was used for survival analysis according to variables in question. Results. The study included 247 patients with a mean age of 60 ± 10 years. There was a predominance of males (74%). The main etiologies of HCC were HCV infection (55%), excessive alcohol consumption (12%), and HBV infection (8%). Liver cirrhosis was present in 92% of cases. The mean tumor number and diameter were 2 and 5 cm, respectively. Patients meeting the Milan criteria corresponded to 43% of the sample. Liver transplantation was performed in 22.4% of patients of the Milan subset and in 10% of the whole sample. The overall mean survival was 60 months, with a 1-, 3- and 5-year survival probability of 74%, 40% and 29%, respectively. Lower survival was observed among patients with alcoholic etiology. Survival was higher among patients submitted to liver transplantation (P < 0.001), TACE (P < 0.001), or any kind of treatment (P < 0.001). However, no difference was found for surgical resection (P = 0.1) or sorafenib (P = 0.1). Conclusion. Patients with HCC were mainly older men diagnosed at an advanced stage. Treatment was associated with better overall survival, but few patients survived to be treated.

Hemorragia digestiva alta / Upper gastrointestinal bleeding

Hemorragia digestiva alta é uma condição grave e potencialmente fatal associada com muitas doenças sistêmicas e gastrointestinais. Embora a mortalidade varia de acordo com a etiologia do sangramento, em geral, é cerca de 10%. Metade desses pacientes têm mais de 60 anos de idade, e neste grupo etário de mortalidade é ainda maior. que podem ser provenientes de várias fontes, principalmente: úlcera péptica, hypertesion portal, anomalias vasculares e neoplasias. Avaliação inicial inclui a estabilização do quadro hemodinâmico e de reposição de sangue sempre que necessário. Endoscopia desempenha um papel importante no diagnóstico e tratamento da maioria das condições de sangramento. O tratamento farmacológico inclui agentes anti-secretores octreotide, e vasopressina. A cirurgia é eventualmente necessário.

Upper gastrointestinal bleeding is a serious and potentially life threatening condition associated with many systemic and gastrointestinal diseases. Although mortality varies according to the etiology of the bleeding, in general, it is around 10%.Half of these patients are over 60 years of age, and in this age group mortality is even higher. it may originate from a number of sources, mainly: peptic ulcer disease, portal hypertesion, vascular anomalies and neoplasms. Initial evaluation includes stabilization of the hemodynamic status and blood replacement whenever necessary. Endoscopy plays an important role in diagnosis and treatment of most bleeding conditions. Pharmacological treatment includes anti-secretory agents, octreotide and vasopressin. Surgery is eventually necessary.

Hemocromatose hereditária: relato de caso e revisão da literatura / Hereditary hemochromatosis: case report and review of the literature

BACKGROUND: HFE-associated hemochromatosis is one of the most common inherited liver disease in Caucasian populations and refers to the association of increased iron stores with tissue damage (e.g., cirrhosis, diabetes, cardiomyopathy), which is progressive when diagnosis and treatment are delayed. AIMS: Description of a case of hereditary hemochromatosis in an asymptomatic 44-years-old patient, whose diagnosis was made through casual identification of abnormal iron markers. We will also present a brief review of the literature about the topic. CONCLUSIONS: Hereditary hemochromatosis is an ideal disease for primary prevention since the disease can be detected well before serious complications develop. This intervention has been shown to prevent the manifestations of the disease, altering its natural history

Correlaçäo entre marcadores séricos e a gravidade histológica da hepatopatia crônica pelo virus C / Correlation between laboratory parameters and histological severity in chronic hepatitis C

O objetivo do estudo foi estabelecer uma possível correlaçäo entre um escore modificado formado por três parâmetros laboratoriais com fibrose avançada e cirrose em pacientes com evidência de hepatite crônica pelo vírus C. Materiais e Métodos: Material obtido por biopsia hepática de 120 pacientes foi estudado. Conforme as alteraçöes histológicas, alocou-se os pacientes em três grupos: aqueles com alteraçöes discretas, com alteraçöes moderadas e com alteraçöes graves. Os três parâmetros laboratoriais foram: plaquetas, razäo ALT/AST e atividades de protombina, os quais foram comparados com resultados da histologia. Resultados: Evidenciou-se uma associaçäo entre o escore e a gravidade histológica na biópsia hepática (p<0,05). Hepatite crônica ativa acentuada e cirrose foram diagnosticadas com 70 por cento de sensibilidade e 95,5 por cento de especificidade utilizando-se como corte 7 pontos. Conclusöes: concluiu-se que o escore formado por três variáveis laboratoriais foi útil para identificar pacientes com hepatite crônica acentuada ou cirrose. Pacientes com valores menores que 7 requerem biópsia hepática para determinar a presença ou näo de cirrose.
