To study sexual transmission of hepatitis D virus (HDV), 52 spouses of 56 index patients were observed and HDV genomes from antibody to HDV (anti‐HDV)‐positive couples were sequenced. Of the spouses, 11 (21%) were serum HBsAg positive, 3 (27%) of whom were also anti‐HDV positive. The HDV sequences between spouses were found to be nearly identical (98% to 98.8%) in the region analyzed (nt 911 to nt 1260). Only one couple showed an identity >90% with the genotype I HDV strains. The HDV sequences… Expand

Evidence of transmission of hepatitis B virus to spouses from sequence analysis of the viral genome

  • Biology, Medicine
  • Journal of gastroenterology and hepatology
  • 1998
TLDR
It is demonstrated that sequence analyses can correlate well with epidemiological findings and confirm the value of the molecular approach for linked infections of HBV through heterosexual contact between spouses. Expand
Intrafamilial transmission of hepatitis delta virus: molecular evidence.
TLDR
In most family units, HDV-infected members harbored nearly identical strains of HDV, and provide molecular support that HDV infection can be transmitted within the family, highlighting the role of inapparent transmission through personal contacts. Expand
Identification of a natural intergenotypic recombinant hepatitis delta virus genotype 1 and 2 in Vietnamese HBsAg‐positive patients
TLDR
The prevalence of intergenotypic recombination between HDV genotypes 1 and 2 in a Vietnamese HBsAg‐positive patient is demonstrated and a newly identified recombinant of HDVgenotype 1 and HDV 2 is reported. Expand
The predominance of hepatitis delta virus genotype I among chronically infected Italian patients
TLDR
It is concluded that in Italy, where HDV infection has been endemic, the overwhelmingly predominant genotype of HDV is genotype I, and this genotype appeared to be associated with a broad spectrum of chronic disease. Expand
Molecular analysis of hepatitis D virus infection in Miyako Island, a small Japanese island
TLDR
A geographical factor was revealed to be significant with regard to HDV infection, which was spread in a closed environment and the HDV genomes on Miyako Island were similar to the Japanese and Taiwan isolates of HDV genotype II. Expand
Dynamics of hepatitis D (delta) virus genotype 3 in the Amazon region of South America.
TLDR
It is suggested that the measures implemented to control HBV transmission resulted in the control of HDV/3 spreading in South America, especially after the important raise in this infection associated with a huge mortality during the 1950s up to the 1970s. Expand
Molecular Phylogenetic Analysis of Iranian HDV Complete Genome
TLDR
Genetic variability and heterogeneity of the HDV species isolated from different geographical areas were confirmed and predicted HDAg sequence of IR-1 revealed the most homology with those of Italian and Lebanese isolates. Expand
Transmission of hepatitis D virus between spouses: A longitudinal study of the first reported Canadian case
TLDR
The ongoing risk of HDV superinfection due to long-term co-habitation or sexual transmission in CHB patients is highlighted, with post-transmission longitudinal sequence revealing specific nucleotide substitutions between both spouse’s HDV genome sequences. Expand
Characterization of hepatitis D virus genotype III among Yucpa Indians in Venezuela.
TLDR
It was concluded that the serious delta hepatitis outbreaks characterized epidemiologically in the Yucpa Amerindians were caused by HDV genotype III isolates that were related to HDV Genotype III isolate from other regions of South America. Expand
The impact of traveling to endemic areas on the spread of hepatitis E virus infection: Epidemiological and molecular analyses
TLDR
E Epidemiological and molecular analyses strongly indicate that most cases of HEV infection originated from travel to HEV‐endemic areas, andHEV infection does occur in this area. Expand

Natural history of hepatitis D viral superinfection: significance of viremia detected by polymerase chain reaction.
TLDR
The acute hepatitis group had the highest detection rate of HDV RNA compared with chronic hepatitis, cirrhosis, hepatocellular carcinoma, and remission groups and the highest alanine aminotransferase (ALT) levels in horizontal and longitudinal analyses. Expand
Evolution rate of hepatitis delta virus RNA isolated in Taiwan
TLDR
It is concluded that HDV RNA in patients' serum is extremely heterogeneous, and that the nucleotide substitutions in certain nucleotide positions likely have conferred evolutionary advantages for HDV. Expand
Molecular cloning and characterization of an isolate of hepatitis delta virus from Taiwan
TLDR
Four highly conserved, long stretches of sequence corresponded to the sequences required for the autocatalytic cleavage activities of the genomic and antigenomic RNAs and the middle and the carboxyl terminal parts of the open reading frame for the delta antigen on the antigenomic strand. Expand
Molecular cloning and sequencing of a human hepatitis delta (δ) virus RNA
TLDR
The cloning and sequencing of an HDV RNA isolated directly from a patient with acute δ-hepatitis showed considerable divergence from that of the chimpanzee-adapted HDV, which showed properties similar to those of viroid or virusoid. Expand
Delta‐agent infection in Taiwan
Based on observations of a limited number of patients, delta (δ) infection has been reported to be infrequent in Taiwan. To further evaluate the role of δ‐infection in patients with hepatitis B virus… Expand
Sexual transmission of hepatitis D virus infection in Taiwan
TLDR
These two groups are not only at high risk for hepatitis D virus infection but also form a reservoir of this virus, it is concluded. Expand
Symptomatic anti‐HBe positive chronic hepatitis B in taiwan with special reference to persistent HBV replication and HDV superinfection
TLDR
Persistent replication or reactivation of HBV and HDV superinfection were the two major causes of clinical exacerbations in anti‐HBe‐positive chronic HBV carriers in Taiwan, and also played an important role in the progression of their liver diseases and unfavorable outcomes. Expand
Heterogeneity and evolution rates of delta virus RNA sequences
TLDR
The sequence obtained from Japanese patient S is the most divergent delta virus isolate yet analyzed, suggesting that delta agent in Japan has a heterogeneous origin and the delta virus RNA sequence from patient S was approximately 81% identical to the previously sequenced strains. Expand
A genotype of hepatitis D virus that occurs in northern South America.
TLDR
The association of a particular genotype with the severe form oftype D hepatitis that occurs in northern South America supports the hypothesis that HDV genetic factors are important determinants in the pathogenesis of type D hepatitis. Expand
