About this study

This study seeks to identify and test host RNA expression profiles in context to protein biomarkers in dried blood spot samples as novel diagnostic markers of neonatal herpes simplex virus infection and to improve the understanding of the pathogenesis of the disease.

Read the detailed description

Background:

Herpes Simplex Virus (HSV) infection in newborns is uncommon but can be devastating and is associated with significant morbidity and mortality. The diagnosis of neonatal HSV infection is challenging because maternal genital herpes often is asymptomatic and the clinical presentation in newborns can be nonspecific, especially in the early disease stages. This results in late diagnosis and potentially terrible consequences for the newborn. The reason why some newborns develop severe disease due to HSV infection is unknown. It has been suggested that immunologic differences in early infancy are the key to further advances. Host RNA expression profiling, transcriptomics, of the host response to infections has shown great potential as clinical tool for diagnostics and for unveiling molecular disease mechanisms. As previously shown, reliable host RNA expression data can be obtained from neonatal dried blood spot (DBS) samples by RNA-sequencing. Proteomic analysis has the potential to simultaneously identify hundreds of protein biomarkers and immune cell populations allowing for detailed mapping of disease immunological pathways.

Method:

A nationwide retrospective case-control study of all newborns with HSV infection in Denmark from 2010 through 2019. DBS samples will be obtained from the Danish Neonatal Screening Biobank, Statens Serum Institut. RNA sequencing and proteomic analyses will be performed at the Danish Center for Neonatal Screening, Department of Congenital Disorders, Statens Serum Institut. Cases will be randomly assigned to a "Discovery cohort" and compared to a control group of newborns matched on gestational age, sex and birthweight will be included.

Time frame:

Sample identification/recruiting: January 1st to January 31st 2022. Sample analysis (RNA sequencing and proteomic analysis): February 1st to April 30th 2022.

Perspectives:

New molecular-based diagnostic tools complementary to conventional methods may improve early diagnosis of neonatal HSV infections and lead to optimised management. In addition, understanding of the pathogenesis at a molecular level of severe disease manifestations of the disease, could form the basis for development of novel interventions for better prevention and treatment.

Study groupRoleWhat they receive
Cases54 newborns with neonatal HSV infection. Interventions: Diagnostic test and disease pathogenesis: Host RNA expression profiling by RNA sequencing and proteomic analyses. Cases will be randomly assigned to a "Discovery Cohort" (identification of diagnostic RNA and proteomic profiles).
Controls108 newborns without infection. Interventions: Diagnostic test and disease pathogenesis: Host RNA expression profiling by RNA sequencing and proteomic analyses. Controls will be randomly assigned to a "Discovery Cohort" (identification of diagnostic RNA and proteomic profiles).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Host RNA expression and proteomic profiles

    To identify specific host RNA expression and proteomic profiles in dried blood spot samples from newborns with HSV infection

    Measured: Admission, age 0-28 days

Secondary outcomes (2)
  1. Disease pathogenesis

    Mapping of disease immunological pathways by simultaneous host RNA expression profiling and proteomic analysis

    Measured: Admission, age 0-28 days

  2. Application of known host RNA profiles

    To test host RNA profiles published in other studies, e.g. based on the genes IFI44L and FAM89A

    Measured: Admission, age 0-28 days

Questions about this trial

What is this clinical trial studying?

An observational study of Neonatal Herpes Simplex Infection and Neonatal HSV Infection, run by Copenhagen University Hospital, Rigshospitalet at 2 sites in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Host RNA expression and proteomic profiles (time frame: Admission, age 0-28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Dec 2022.
