| prevalence of hepatitis viruses in an anti-human immunodeficiency virus-positive population from argentina. a multicentre study. | the objectives of this study were to investigate the prevalence of infections with hepatotrophic viruses in an anti-human immunodeficiency virus (hiv)-positive population from buenos aires and to compare it among the main risk groups for hiv infection. four hundred and eighty-four consecutive patients attending the hiv outpatients clinic were studied: 359 men and 125 women, median age 29 years (range 16-67 years); 35.5% had presented acquired immune deficiency syndrome (aids)-defining conditions ... | 1999 | 10847130 |
| identification of the first strain of swine hepatitis e virus in south america and prevalence of anti-hev antibodies in swine in argentina. | in argentina, a country considered non-endemic for hepatitis e virus (hev) infection, serologic evidence of hev infection has been observed in different human population groups. in other countries, a high degree of genetic relatedness has been observed between human and swine hev genotype 3 sequences, suggesting zoonosis as one probable route of infection. this is the first identification of swine hev in south america. hev rna was detected and sequenced in the orf 1 and orf 2 regions from swine ... | 2006 | 17063523 |
| [molecular characterization of hepatitis e virus in three acute liver failure cases in children in argentina]. | strains of hepatitis e virus (hev) isolated from argentinian patients with sporadic hepatitis, as well as from swine from argentina, belong to genotype 3. hev genotype 3 variants have been described associated with acute liver failure (alf) in adults from japan and the united kingdom. in argentina, 30% of alf in adults and children are of unknown aetiology. to study if hev could be an aetiological agent associated with alf in children, serum and/or fecal samples fjom 35 children (mean age: 6 yea ... | 2006 | 17407988 |
