Abstract

Background:

The impact of Enterovirus Real Time-Polymerase Chain Reaction assay (EV RT-PCR) on hospitalization lengths of patients with aseptic meningitis has been investigated but the impact of early EV RT-PCR results released on time before patient discharge remains unclear during Echovirus meningitis outbreaks.

Objective:

To assess a potential correlation between EV RT-PCR turn-around time and hospitalization lengths during an Echovirus meningitis outbreak.

Method:

Eighteen patients demonstrating a positive EV RT-PCR assay performed on Cerebrospinal Fluid (CSF) samples collected between October 1st 2014 and December 31st 2014 were retrospectively included. Viral protein 1 (VP1) gene region was amplified and sequenced using a classical Sanger sequencing reaction. Clinical data were retrospectively collected from patient’s records. Quantitative variables expressed as median values and ranges were compared using Mann Whitney U test. Correlations were performed using simple regression analysis.

Results:

Phylogenetic VP1 sequence analyses identified that the outbreak was related to an Echovirus 30 strain in 7 out of the 10 cases with available sequencing data. The three remaining sequences analyses evidenced Echovirus 14, 9 and 7 strains. Hospitalization length was statistically shorter in children without comorbidity (n=5) than in adult patients (n=10) or neonates and children with comorbidity (n=3) (p=0.003 and 0.01 respectively), whereas EV RT-PCR turnaround time was not statistically different between these groups. Correlation between hospitalization length and EV RT-PCR turnaround time was poor (R2=0.06), especially in adults (R2=0.01)

Conclusion:

Our data indicated that EV RT-PCR turnaround time was not correlated to hospitalization length during a short Echovirus meningitis outbreak.

Keywords: Hospitalization length, Enterovirus, Outbreak, Aseptic meningitis, Real-time polymerase chain reaction, Cerebrospinal fluid.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
