| prevalence of anti-hepatitis a antibodies in an urban middle class area of argentina: some associated factors. | this study evaluated the seroprevalence of hepatitis a virus (hav) antibodies in 360 middle-class subjects from buenos aires city and its outskirts. | 2000 | 10689212 |
| clinical implications of hepatitis a virus ribonucleic acid detection and genotyping in acute liver failure in children in argentina. | to investigate the detection of hepatitis a virus ribonucleic acid in patients with acute liver failure and to assess if the results have any clinical implications for the evolution of acute liver failure in children. hepatitis a infection, a vaccine-preventable disease, is an important cause of acute liver failure in children in argentina. universal vaccination in 1-yr-old children was implemented in june 2005. | 2010 | 20101195 |
| genetic characterization of hepatitis a virus isolates from buenos aires, argentina. | the hepatitis a virus (hav) has been classified in seven different genotypes, which include human (i, ii, iii, and vii) and simian (iv, v, and vi) groups. the sequence analysis of hav strains contributes to the molecular epidemiology of the virus. although the infection with hav is endemic in argentina and vaccination is being implemented in this country, using both ia and ib strains, there are very few data on the genotypes of the circulating viruses. on the basis of the sequences of 20 isolate ... | 2002 | 12210404 |
| 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 |
| [hepatitis a virus infection in children in argentina: a pilot study]. | the severity and/or the prognostic of infections with the hepatitis a virus (hav) is related to the age at which the infection occurs. since transmission of the virus occurs by the fecal-oral route, the prevalence and age-relate incidence of infection is determined by the adequacy of sanitation hygienic measures and the socio economic level of exposed populations. thus, the disease is having an increasing impact in developing countries with improving sanitary standards whereas inhabitants of ind ... | 1997 | 9460514 |
