ABSTRACT
El rol de los virus respiratorios distintos de influenza en las infecciones respiratorias agudas en los adultos mayores ha sido probablemente subestimado. En los últimos años, los avances en técnicas moleculares de diagnóstico han hecho posible la identificación rápida del virus sincicial respiratorio humano (HRSV). Realizamos un estudio prospectivo observacional para evaluar el rol del HRSV en mayores de 65 años que se hospitalizaron por infecciones respiratorias en nuestra institución, ubicada en la ciudad de La Plata, provincia de Buenos Aires. Fueron reclutados 124 pacientes y el HRSV se detectó en 13, influenza B en 9 e influenza A en 8. La presentación clínica más frecuente de los The role of respiratory viruses other than influenza in acute respiratory tract infections among elderly adults has probably been underestimated. Recent advances in molecular diagnosis have made the rapid identification of human respiratory syncitial virus HRSV infection possible. We conducted a prospective observational study to evaluate the role of HRSV in elderly patients (>65 years of age) hospitalized for acute respiratory infections. A total of 124 patients were recruited, HRSV infection was identified in 13 patients, Influenza B in 9 patients and influenza A in 8 patients. The most frequent clinical presentation was bronchospasm and the infection was prevalent in patients with comorbidities. HRSV infections accounted for an important number of hospital admissions and has been associated with high mortality rates (23%). pacientes con HRSV fue el broncoespasmo y afectó principalmente a personas con comorbilidades. HRSV fue responsable de un número importante de internaciones por enfermedad respiratoria aguda en mayores de 65 años en nuestra institución y se asoció a mortalidad elevada (23%).
