2. 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

3. Hepatitis Delta Prevalence in South America: A Systematic Review and Meta-Analysis
Abstract Hepatitis delta virus (HDV) has been associated with acute or chronic hepatitis in Latin America, but there is no prevalence study covering South American countries. This meta-analysis aimed to estimate anti-HDV prevalence through a systematic review of published articles in English, Portuguese and Spanish until December 2017. Searches were conducte

4. Acquired hepatocerebral degeneration in a patient with hepatitis B and hepatitis delta virus coinfection
Abstract Acquired hepatocerebral degeneration is a neurological syndrome with typical clinical (extrapyramidal and neuropsychiatric) symptoms and brain magnetic resonance imaging findings (high T1 signal in the globus pallidus). It occurs mainly in patients with advanced liver disease, such as in patients co-infected with hepatitis B virus (HBV) and hepatiti

5. Correlation between TH1 response standard cytokines as biomarkers in patients with the delta virus in the western Brazilian Amazon
Hepatitis D virus (HDV) is endemic in the Amazon Region and its pathophysiology is the most severe among viral hepatitis. Treatment is performed with pegylated interferon and the immune response appears to be important for infection control. HDV patients were studied: untreated and polymerase chain reaction (PCR) positive (n = 9), anti-HDV positive and PCR n

6. Estudos sobre infecções pelos vírus da hepatite B (HBV), hepatite C (HCV), hepatite delta (HDV) e vírus GB-C (GBV-C) em diferentes regiões da América do Sul / Studies on viral infections by hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis delta virus (HDV) and GB virus C (GBV-C) in different regions of South America
As hepatites virais estão entre as mais importantes pandemias mundiais da atualidade. Existem várias causas de hepatite, entre elas, o vírus da hepatite B (HBV), o vírus da hepatite C (HCV) e o vírus da Hepatite Delta (HDV). Da mesma forma, o vírus GB-C (GBV-C) é importante na coinfecção com outros vírus, como o HIV. Nesse estudo, várias regiões

7. Aspectos epidemiológicos da infecção pelo vírus da hepatite c e coinfecções com os vírus b e delta no estado do Acre, Amazônia ocidental brasileira
Background. Viral hepatitis are leading complex public health issue worldwide,particularly chronic hepatitis B, C and D because of the risk for cirrhosis andhepatocellular carcinoma development. Amazon basin is for long recognized ashyperendemic for B and D virus but originally supposed to be indene for HCV, althoughits introduction into remote Amazon commun

8. Prognóstico Clínico de Pacientes Co-infectados com os Vírus da Hepatite Delta e B com e sem Infecção pelo HIV: na Era da Terapia Antiretroviral de Alta Atividade (HAART) a Infecção pelo HIV Ainda Piora o Desfecho Clínico dos Pacientes?
Embora não muito comum, o curso clínico da co-infecção do vírus da hepatite B (VHB) e do vírus da hepatite delta (VHD) geralmente é pior. Um prognóstico ainda pior pode ser esperado em pacientes co-infectados HBV-HDV e com infecção pelo vírus da imunodeficiência humana (HIV). Entretanto, existem poucos dados na literatura sobre o tema, especialme

9. CARACTERIZAÇÃO CLÍNICA, BIOQUÍMICA, SOROLÓGICA E MOLECULAR DA HEPATITE DELTA NO ESTADO DE RONDÔNIA
O propósito deste estudo retrospectivo foi correlacionar as características clínica, bioquímica, sorológica e molecular da hepatite delta em pacientes atendidos no ambulatório de referência para hepatites no estado de Rondônia, na Amazônia Ocidental Brasileira, durante o período de outubro de 1993 a outubro de 2004. De um total de 109 pacientes com

10. The large form of hepatitis delta antigen is crucial for assembly of hepatitis delta virus.
The virions of hepatitis delta virus (HDV) contain two species of HDV-specific protein, a large and a small form of hepatitis delta antigen (HDAg). We examined the role of individual HDAgs in virion assembly in cotransfection experiments. First, we constructed a replication-competent HDV mutant expressing only the small HDAg. When cotransfected with a plasmi

11. Assembly of hepatitis delta virus particles.
Hepatitis delta virus (HDV) is a subviral satellite of hepatitis B virus (HBV). Since the RNA genome of HDV can replicate in cultured cells in the absence of HBV, it has been suggested that the only helper function of HBV is to supply HBV coat proteins in the assembly process of HDV particles. To examine the factors involved in such virion assembly, we trans

12. Characterization of hepatitis delta antigen: specific binding to hepatitis delta virus RNA.
It has previously been shown that human hepatitis virus delta antigen has an RNA-binding activity (Chang et al., J. Virol. 62:2403-2410, 1988). In the present study, the specificity of such an RNA-protein interaction was demonstrated by expressing various domains of the delta antigen in Escherichia coli as TrpE fusion proteins and testing their RNA-binding a
