1. Quantification of C4d deposition and hepatitis C virus RNA in tissue in cases of graft rejection and hepatitis C recurrence after liver transplantation
Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divide

2. Health related quality of life among patients with chronic hepatitis C: a cross-sectional study of sociodemographic, psychopathological and psychiatric determinants
INTRODUCTION: Chronic hepatitis C virus infection patients have higher rates of psychiatric disorders than the general population. Chronic hepatitis C virus infection is known to be associated with impaired health related quality of life. To our knowledge, there is no previous research of health related quality of life in chronic hepatitis C patients that co

3. Performance of diagnostic biomarkers in predicting liver fibrosis among hepatitis C virus-infected Egyptian children
The aim of the present study was to identify specific markers that mirror liver fibrosis progression as an alternative to biopsy when biopsy is contraindicated, especially in children. After liver biopsies were performed, serum samples from 30 hepatitis C virus (HCV) paediatric patients (8-14 years) were analysed and compared with samples from 30 healthy sub

4. Seroprevalence of hepatitis B and hepatitis C markers among children and adolescents in the south brazilian region: metropolitan area of Florianópolis, Santa Catarina
Hepatitis B and C are important causes of morbidity and mortality worldwide. In Brazil, according to the Ministry of Health, about 15% of population is infected by hepatitis B virus (HBV) and less than 1% by hepatitis C virus (HCV). Nevertheless, the age-specific prevalence of HBV and HCV markers remains unknown. This study aimed to determine the seroprevale

5. Differential gene expression profiles of hepatocellular carcinomas associated or not with viral infection
Chronic hepatitis B (HBV) and C (HCV) virus infections are the most important factors associated with hepatocellular carcinoma (HCC), but tumor prognosis remains poor due to the lack of diagnostic biomarkers. In order to identify novel diagnostic markers and therapeutic targets, the gene expression profile associated with viral and non-viral HCC was assessed

6. Characterization of Hepatitis C Virus infection in Amazon blood donors, Brazil / Caracterização sorológica e molecular da infecção pelo vírus da hepatite C (HCV) em doadores de sangue do Estado do Amazonas
Na prática hemoterápica em todo mundo, a triagem e o diagnóstico da infecção pelo HCV continua sendo um desafio. Desta forma, considerando as variáveis genéticas do vírus da Hepatite C e as variáveis populacionais de cada região, o conhecimento mais profundo da realidade da epidemiologia molecular do vírus da Hepatite C na população de doadores

7. Determinação do RNA-VHC no sêmen de pacientes cronicamente infectados pelo vírus da Hepatite C / Determinations of the RNA-HCV in semen from chronically patients infected by the hepatitis C vírus
Introduction: Hepatitis C vírus is a huge problem for public health, and its global prevalence is estimated around 3%. Its transmission by seminal fluid is still in discussion in several fields, such as assisted reproduction and in studies about risk factors, whether the hepatitis C virus is an STD (sexually transmitted disease) or not. Twenty-three patient

8. Análise dos fatores de risco para peritonite bacteriana espontânea em pacientes cirróticos e do perfil da flora infectante com o uso de antibióticos profiláticos / Analysis of risk factors for spontaneous bacterial peritonitis in cirrhotic patients and the ascitic fluid microbiology with use of prophylactic antibiotics
INTRODUCTION: Invasive procedures and the decline of the liver function have been considered predisposing factors for spontaneous bacterial peritonitis (SBP) in cirrhotic patients. In spite of the predominance of gram negative, the incidence of gram positive agents is increasing in literature. OBJETIVES: To analyze the risk factors for SBP in cirrhotic patie

9. A contribuição da epidemiologia de campo para o estudo das doenças infecciosas e a saude publica / The contributions of field epidemiology to the estudy of infectious diseases and public health
Field epidemiology is an area of science that uses principles of classic epidemiology to respond to public health threats and improve the quality of life of a given population. In addition to classic epidemiology, the field epidemiologist uses knowledge from other areas such as economics, anthropology, social sciences, and communications to develop and imple

10. Expressão e purificação de uma proteína multiepítopo recombinante desenhada a partir de proteínas do vírus da hepatite C
Hepatitis C is considered one of the largest problems of public health in the world, inclusively in Brazil, whereas a preventive vaccine none is available; the number of asymptomatic infections is elevated and for control of the disease, there exist only imported kits. Considering, principally, the increase of preoccupation with the detection of precocious h

11. Perfil genotípico do HCV em portadores de hepatite C em Belo Horizonte, Minas Gerais Brasil/
Hepatitis C virus (HCV), like other RNA virus, is characterized by a high genomic heterogeneity. To date, six different genotypes have been identified, with distinct geographical distribution. HCV genotype identification is essential in clinical practice, since therapeutic schedule and the probability of viral response are genotype-specific. The reference me

12. Genetic variability of hepatitis A virus strain HAF-203 isolated in Brazil and expression of the VP1 gene in Escherichia coli
The hepatitis A virus (HAV) HAF-203 strain was isolated from an acute case of HAV infection. The primary isolation of HAF-203 in Brazil and its adaptation to the FRhK-4 cell lineage allowed the production of large amounts of viral particles enabling molecular characterization of the first HAV isolate in Brazil. The aim of our study was to determine the nucle
