Evaluation of two commercial enzyme immunoassays for the detection of norovirus in faecal samples from hospitalised children with sporadic acute gastroenteritis

Abstract: Two commercially available enzyme immunoassays (EIAs), IDEIA and Ridascreen, for norovirus antigen detection were evaluated with 117 faecal samples from hospitalised children with acute gastroenteritis. Eighteen of 39 samples positive by RT-PCR were characterised by sequence analysis, and 17 of these were related to norovirus genogroup II. When compared with RT-PCR, the sensitivity and specificity values were 76.9% and 85.9%, respectively, for the IDEIA assay, and 59.0% and 73.1%, respectively, for the Ridascr… Show more

“…La falta de diagnóstico etiológico de diarreas es frecuente, de ahí la importancia de incorporar técnicas diagnósticas más sensibles ya que los tests de rutina generalmente resultan negativos 2,7,8 . La detección de NoV es difícil debido a la gran variabilidad genética que dificulta el diagnóstico de laboratorio de rutina; la técnica de ELISA tiene una baja sensibilidad que obliga a una confirmación de un resultado negativo por métodos moleculares 32,41,43 . La introducción del diagnóstico empleando RPC en tiempo real ha sido de gran importancia para mejorar el diagnóstico y establecer el rol relevante de NoV en brotes epidémicos agudos y en casos esporádicos de diarrea.…”

“…La introducción del diagnóstico empleando RPC en tiempo real ha sido de gran importancia para mejorar el diagnóstico y establecer el rol relevante de NoV en brotes epidémicos agudos y en casos esporádicos de diarrea. Este método diagnóstico ha permitido demostrar la amplia heterogeneidad y rápida evolución de las variantes genéticas de NoV 8,9,[11][12][13][14][15] ; La diversidad antigénica y la falta de sistema de cultivo in vitro del virus mantendrá al diagnóstico molecular como el mejor método de detección de NoV. La RPC a tiempo real ha emergido como el estándar para el diagnóstico y detección de NoV, ya que combina un alto rendimiento, reproducibilidad, sensibilidad y especificidad 11,27,[42][43][44][45][46] . El 36,6% de los pacientes en este estudio fueron ingresados al hospital con un diagnóstico diferente al de una gastroenteritis, adquiriendo la infección probablemente en forma nosocomial (plazo de latencia para los síntomas de 3 o más días), siendo mayor para NoV (32,1%) que para RV (5,7%).…”

“…Rapid commercial assays, such as enzyme immunoassays (EIAs) have been cleared by the US Food and Drug Administration to detect norovirus antigen in stool samples during outbreaks. However, due to the poor sensitivity of EIAs [51], samples with negative results should be confirmed by a second technique, such as RT-qPCR [52]. Consequently, EIA kits should not replace molecular methods during outbreak investigations, and caution should be used when interpreting test results from sporadic cases [52].…”
