Comparative Evaluation of Effectiveness of IAVchip DNA Microarray in Influenza A Diagnosis

Abstract: The paper describes comparative evaluation of IAVchip DNA microarray, reverse transcription PCR (RT-PCR), and real-time RT-PCR versus virus isolation in chicken embryos and shows their diagnostic effectiveness in detection and subtyping of influenza A virus. The tests were evaluated with use of 185 specimens from humans, animals, and birds. IAVchip DNA microarray demonstrates higher diagnostic effectiveness (99.45%) in early influenza A diagnosis as compared to the real-time PCR (98.38%) and RT-PCR (96.22%), t… Show more

“…There is limited information on the diagnostic utility of these new tests. A study by Sultankulova et al compared viral isolation of Influenza A with DNA microarray technology, reverse transcription PCR and real-time PCR [ 23 ]. Microarray technology showed a higher sensitivity (99.5%) and similar specificity (98.5%) to real-time PCR.…”

“…The diagnosis of virus types based on microarray technology can improve the quality and shorten the analysis duration in molecular diagnosis of infectious diseases. Moreover, it can satisfy the needs of simultaneous detection of multiple viruses and screening large numbers of pathology samples [32, 33]. Microarray assays for avian diseases have been previously reported.…”

“…El porcentaje de muestras positivas para virus influenza en nuestra cohorte es similar a países de otros continentes durante el mismo periodo de observación 12,13 . Nuestros resultados se relacionan con lo documentado por Arango AE y colaboradores, en el Hospital Pablo Tobón Uribe en la ciudad de Medellín durante los años 2007 a 2012, donde detectaron virus influenza en 20,8% de los casos, aunque con la ventaja de emplear RT-PCR y cultivo viral 14 y con dos estudios descriptivos con los mismos 5 años de observación (2009 a 2013), realizados en India 15 y Niger 16 , donde influenza A(H1N1)pdm09 es el más frecuente de todos los virus influenza, seguido de A(H3N2) e influenza B. Nuestra positividad es baja comparada con lo descrito por Remolina YA y colaboradores, en casos de IRAG atendidos en 7 hospitales de tercer nivel en la ciudad de Bogotá durante el año 2012, donde documentaron infección viral en 69,2%, y 30,8% de influenza, de los cuales influenza A correspondía a 75% 17 , aunque el diagnóstico molecular para este estudio se hizo mediante la técnica de micro matrices para detección de genoma viral, que puede llegar a tener una mayor sensibilidad que la RT-PCR 18 .…”
