SOLOAGA, Rolando et al. Estudio multicéntrico argentino sobre la utilidad del panel de neumonía de FilmArray®. Acta bioquím. clín. latinoam. [online]. 2021, vol.55, n.3, pp.347-355. ISSN 0325-2957.

Lower respiratory tract infections are among those in which the inappropriate use of antimicrobials is common, so it is essential to have a rapid, sensitive and specific diagnostic test. The FilmArray system is a multiplex PCR assay with a pneumonia panel that includes 26 microorganisms and 7 antibiotic resistance markers. The objectives of this study were: a) to establish the correlation between quantitative cultures for bacterial agents from lower respiratory tract samples (MRVB) and the phenotypic detection of resistance mechanisms with the corresponding results of FilmArray b) to determine the therapeutic change generated with the immediate result report. A total of 194 MRVB corresponding to 191 patients with pneumonia were included and 277 bacterial strains were documented. FilmArray identified 253/277 (91%) bacteria and 161/277 (58%) were isolated from culture, 58 (23%) matched the same count, 116 (46.7%) yielded higher counts with FilmArray, and 72 (28.9%) with negative culture were detected by this method. Antibiotic resistance markers were detected in 63 strains, but only 28 were confirmed by phenotypic methods. These results may cause changes in the antimicrobial treatment in 74.6% (174/194). FilmArray is a useful tool to optimize antimicrobial therapy in patients with pneumonia.
