Risonanza Magnetica (RM) renale per la valutazione quantitativa del sovraccarico di ferro con sequenze T2*: valori normali per età e sesso.
2016
The objective of this study is to examine the reliability and reproducibility of multi-echo gadient-echo (ME-GRE) T2 sequences for the measurement of global and regional renal T2 values, establish normal cut-offs in healthy patients and evaluate the correlation of values obtained with age and sex.
VALUTAZIONE DI DUE TEST IMMUNOCROMATOGRAFICI PER LA DIAGNOSI DI INFEZIONE DA ROTAVIRUS
2017
Obiettivo dello studio: Valutare l’efficienza diagnostica di due tecniche immunocromatografiche (IC) utilizzate per la ricerca di antigeni di Rotavirus di gruppo A (RVA) nei campioni fecali: CerTest Rotavirus+Adenovirus (Biotec) e Vikia Rota+Adeno (bioMérieux). relazione Entrambe le tecniche IC sono state confrontate con la PCR RealTime, considerata il gold standard per la diagnosi delle enteriti da RVA. I RVA sono i principali agenti eziologici di gastroenterite acuta (AGE) nei bambini al di sotto dei 5 anni di età, con elevati tassi di morbilità e mortalità nelle diverse aree geografiche. Metodi impiegati: Uno studio retrospettivo è stato eseguito su 2096 campioni fecali, raccolti dal 200…
Waterborne Norovirus outbreak at a seaside resort likely originating from municipal water distribution system failure
2018
AbstractIn May 2016 a Norovirus (NoV) gastroenteritis outbreak involved a high school class visiting a seaside resort near Taormina (Mascali, Sicily). Twenty-four students and a teacher were affected and 17 of them showed symptoms on the second day of the journey, while the others got ill within the following 2 days. Symptoms included vomiting, diarrhoea and fever, and 12 students required hospitalisation. Stool samples tested positive for NoV genome by Real-Time polymerase chain reaction assay in all 25 symptomatic subjects. The GII.P2/GII.2 NoV genotype was linked to the outbreak by ORF1/ORF2 sequence analysis. The epidemiological features of the outbreak were consistent with food/waterbo…
Performance analysis of two immunochromatographic assays for the diagnosis of rotavirus infection
2017
Group A rotaviruses (RVAs) are the primary cause of acute gastroenteritis (AGE) in young children worldwide. Several commercial tests including latex agglutination, enzyme-linked assays (ELISA) and immunochromatographic tests (ICT) have been developed for the diagnosis of RVA infection. In the present study, the performance of two commercially available one-step chromatographic immunoassays, CerTest Rotavirus + Adenovirus (Biotec S.L, Zaragoza, Spain) and Vikia Rota-Adeno (bioMerieux SA, Lyon, France) were retrospectively evaluated using Real-time PCR as reference test. Re-testing by Real-time PCR of 2096 stool samples of children hospitalized with AGE previously screened by ICTs (1467 by C…
Norovirus GII.17 as Major Epidemic Strain in Italy, Winter 2015–16
2017
In winter 2015-16, norovirus GII.17 Kawasaki 2014 emerged as a cause of sporadic gastroenteritis in children in Italy. Median patient age was higher for those with GII.17 than GII.4 infection (55 vs. 24 months), suggesting limited cross-protection for older children.
Performance evaluation of gastrointestinal viral ELIte panel multiplex RT-PCR assay for the diagnosis of rotavirus, adenovirus and astrovirus infecti…
2019
Rotavirus, adenovirus, norovirus and astrovirus are considered to be among the major causes of sporadic cases and outbreaks of acute gastroenteritis globally. Rapid and accurate identification of enteric viruses is still a challenge for the clinical laboratory. Recently, several molecular platforms for the detection of viral enteric pathogens have become available. In this study, the diagnostic accuracy of InGenius Gastrointestinal Viral (GV) Elite Panel, a newly developed one-step multiplex real-time RT-PCR assay simultaneously detecting rotavirus, adenovirus and astrovirus, was evaluated retrospectively analyzing an archival collection of 128 stool samples of children hospitalized with ac…
Molecular evolutionary analysis of type-1 human astroviruses identifies putative sites under selection pressure on the capsid protein
2017
Human astroviruses (HAstV) are important enteric pathogens that can be classified into eight sero/genotypes (HAstV-1 to -8). Although the various HAstV types show global spread, type-1 strains tend to be predominant. Molecular analysis of the genomic region encoding the capsid protein (ORF2) has revealed discrete sequence variation, with different lineages within each HAstV type and at least three major lineages have been identified within HAstV-1. Longitudinal epidemiological surveillance has revealed temporal shift of the various HAstV-1 lineages. Metadata analysis of HAstV-1 sequences available in the databases also revealed temporal shifts of the circulation of HAstV-1 lineages, suggest…
Performance evaluation of a newly developed molecular assay for the accurate diagnosis of gastroenteritis associated with norovirus of genogroup II
2018
The performance of a newly proposed fully automated cassette-based sample-to-results solution for norovirus (NoV) detection, InGenius Norovirus ELITe MGB®, was evaluated. A total of 120 selected archival stool samples from children hospitalized for acute gastroenteritis were used to compare the results to a reference real-time RT-PCR. The InGenius NoV assay showed optimal diagnostic accuracy (sensitivity, 100%; specificity, 95.7%) and was able to correctly detect the entire wide panel of epidemiologically relevant genotypes tested. These preliminary results suggest that the InGenius NoV assay can be recommended as a valuable method for accurate diagnosis of NoV GII infection in epidemic and…
