13. Hepatitis B virus infection among oncohematologic disease patients in Central Brazil: prevalence, risk factors and immunization
ABSTRACT Introduction: Carriers of oncohematological diseases are at high risk for hepatitis B virus (HBV) infection. Objective and method: To investigate the epidemiology of HBV infection in Goiânia, Central Brazil, 322 individuals with oncohematological diseases (leukemias, Hodgkin lymphoma and non-Hodgkin lymphoma) were interviewed and blood samples we

14. Serum regucalcin is a useful indicator of liver injury severity in patients with hepatitis B virus-related liver diseases
Regucalcin is a soluble protein that is principally expressed in hepatocytes. Studies of regucalcin have mainly been conducted in animals due to a lack of commercially available kits. We aimed to develop an enzyme-linked immunosorbent assay (ELISA) to quantify serum regucalcin in patients with hepatitis B virus (HBV)-related disease. High-titer monoclonal an

15. Exploratory spatial analysis of HBV cases in Brazil between 2005 and 2017
RESUMO Objetivo: Analisar o padrão de distribuição espacial dos casos de hepatite causada pelo vírus B (HBV) e a mortalidade atribuída a esse agravo em todo o território nacional, nos anos de 2005, 2016 e 2017. Métodos : Trata-se de um estudo ecológico de análise espacial, utilizando dados do Sistema de Informação de Agravos de Notificação e d

16. Hepatitis B and Delta: clinical aspects of patients in the Brazilian Western Amazonia
RESUMO Objetivo: Analisar aspectos clínicos, sorológicos, bioquímicos e hematológicos entre pacientes infectados por vírus das hepatites B (VHB) e Delta (VHD). Método: Estudo transversal, descritivo, retrospectivo, realizado com pacientes cronicamente infectados por VHB e superinfectados por VHD. Resultados: Entre os 112 pacientes selecionados, 74%

17. Molecular epidemiology of Hepatitis delta virus infection in Minas Gerais state from Brazil, an area outside the hyperendemic region of the Amazon Basin
BACKGROUND Hepatitis delta virus (HDV) infections in hepatitis B virus (HBV) carriers are the most severe form of viral hepatitis. HDV prevalence is high in the Brazilian Amazon, but studies in other regions of the country are still scarce and often underestimated its prevalence by including a small numbers of individuals. OBJECTIVE This study aimed to de

18. Up-regulation of RIP1 and IPS-1 in chronic HBV infected patients
Abstract IPS-1 and RIP1 are the main downstream molecules of RIG1 and MDA5, as intracytoplasmic receptors, which are the main receptors involved in recognition of internal and external viral double-stranded RNA. In this project, mRNA levels of IPS-1 and RIP1 were investigated in the peripheral blood immune cells of chronic hepatitis B (CHB) patients. IPS-1 a

19. Inhibitory Effect on the Hepatitis B Cells through the Regulation of miR-122-MAP3K2 signal pathway
Abstract: The aim of this study was to investigate the inhibitory effect of regulation of miR-122-MAP3K2 signal pathway on the hepatitis B cells. We detected the content of MAP3K2 from patients with HBV blood serum samples and analyzed the correlation between content of MAP3K2 and copies of HBV-DNA. Wound healing and Transwell assays were used to detect the

20. Anti-Hepatitis B Antibody Levels In Immunized Medical Students: Are They At Risk?
Abstract INTRODUCTION Medical students have an occupational risk for hepatitis B (HB). This study sought to determine anti-HBs and anti-HBc IgG levels in vaccinated students, check their seroconversion, and correlate this with vaccination. METHODS One hundred and forty-three students’ blood samples and their vaccination schedules were analyzed. RESULT

21. Challenging Management of Hepatitis B infection in Ankylosing Spondylitis Patients in an Endemic Area during Immunosuppressive Therapy
Abstract Hepatitis B infection is a global health issue. When considering patients with rheumatic diseases, this is no different. By using immunosuppressant drugs, such as DMARDs and biologics, viral reactivation is possible, leading to serious consequences on the patient. We report 3 cases of association between ankylosing spondylitis and hepatitis B with t

22. Association of serum levels of C-reactive protein with CRP-717 T/C polymorphism and viremia in HCV and HBV carriers
Abstract INTRODUCTION: The present study investigated the association of the rs2794521 polymorphism in the CRP gene in individuals with chronic hepatitis B and C, correlating it with markers of hepatic inflammation, fibrosis scores, viral load, and plasma protein levels. METHODS: The study analyzed 185 blood samples obtained from patients with hepatitis B

23. Decline in hepatitis B and C prevalence among hemodialysis patients in Tocantins, Northern Brazil
ABSTRACT Infection control measures have been responsible for a decline in the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in hemodialysis patients. In Brazil, these measures have been in place since 1996. The aim of this study was to evaluate the current HBV and HCV epidemiology among hemodialysis patients in the State of To

24. Phylogenetic analysis and genotype distribution of Hepatitis B Virus (HBV) in Roraima, Brazil
ABSTRACT Hepatitis B virus (HBV) infection is a serious global health problem. HBV has a high viral genetic diversity, with 10 genotypes recognized. In Brazil, the Roraima State is the third in the Northern region regarding the number of hepatitis B cases. On the other hand, few data on HBV genotyping and phylogenetic analysis are available. The purpose of t
