| evidence of human metapneumovirus in children in argentina. | human metapneumovirus (hmpv) is a virus, which was first associated with acute lower respiratory infection in children but is detected currently in all age groups. clinical symptoms are similar to those described for respiratory syncytial virus (rsv) infections, ranging from mild respiratory illness to severe bronchiolitis and pneumonia in children. to date, no cases of hmpv have been reported in argentina. in this study, 440 respiratory samples obtained during the period 1998-2002 from children ... | 2004 | 14695673 |
| differential production of inflammatory cytokines in primary infection with human metapneumovirus and with other common respiratory viruses of infancy. | viral respiratory infections are the most frequent cause of hospital admission for infants and young children during winter. however, the mechanisms of illness that are associated with viral lower-respiratory-tract infection (lri) are unclear. a widely accepted hypothesis attributes the pathogenesis of viral lri in infants to the induction of innate inflammatory responses. this theory is supported by studies showing that toll-like receptor 4 is activated by respiratory syncytial virus (rsv), lea ... | 2004 | 15143472 |
| the impact of infection with human metapneumovirus and other respiratory viruses in young infants and children at high risk for severe pulmonary disease. | we conducted a prospective, observational study to characterize the clinical manifestations of respiratory infections caused by human metapneumovirus (hmpv) and other viruses in 194 premature infants and young children with chronic lung disease or congenital heart disease in buenos aires. children had 567 episodes of respiratory illness and were monitored until they were 2 years old or until the completion of the study. hmpv elicited 12 infections (2%) year-round; 30% were of moderate or greater ... | 2006 | 16652283 |
| epidemiological study of influenza virus infections in young adult outpatients from buenos aires, argentina. | influenza virus is the most common cause of influenza-like illness (ili) in adults. in argentina, studies on influenza and other respiratory viruses were performed mostly in pediatric populations. | 2008 | 19453464 |
