Resumen

BUDNIK O, ISOLDA et al. Contribution of multiplex respiratory molecular panel to the diagnosis of acute respiratory infections. Rev. chil. enferm. respir. [online]. 2016, vol.32, n.4, pp.224-232. ISSN 0717-7348.  http://dx.doi.org/10.4067/S0717-73482016000400003.

Objective: To assess the performance of multiplex-PCR for diagnosis of respiratory viruses in parallel with direct fluorescence assay (DFA). We assessed the performance and co-infection diagnosis of molecular respiratory panel PCR (MRP-PCR) and DFA in hospitalized and outpatients. Results: 8535 samples were included, 1792 tested by MRP-PCR (46.9% positive) and 6743 by DFA (35.1% positive). MRP-PCR diagnosed co-infection in 21.3% and DFA in 1.8% of the samples. Rhinovirus was the most common virus in any age group. In 210 patients both tests were done; 100 were positive by MRP-PCR and 18 by DFA. Positive concordance value was 6.2%. 85 samples were positive only by MRP-PCR and in 42 of them only novel respiratory viruses were identified. Performance of MRP-PCR was statistically significant compared DFA for traditional respiratory viruses. Discussion: Multiplex PCR has shown better sensitivity, may expand the etiologic spectrum of respiratory infections and detect a higher number of co-infections.
