About this study

Official title: Comparison of Serological Tests for the Varicella-zoster Virus and Correlation With the Memory of the Infection or Vaccination

Comparison of the sensibility and specificity of 3 different serological tests and evaluation of chicken pox immunity in pregnant women.

Secondary goals :

  • Correlation memory / Immunity;
  • Prevalence of VZV immunity in pregnant women;
  • Evaluation of cellular and humoral immunity in cases with discrepancy between tests or between test and memory;
  • Evaluation of acceptability of vaccination in the post partum period in non immune patients.

Methods Not randomized prospective study,

Number of patients : 400 Duration : 36 months Inclusion criteria : pregnant women >18years old, agree to participate (written consent) Exclusion criteria: auto immune disease, HIV +, grafted patients

What is being measured

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

  1. Rate sensitivity and specificity in negative and dubious zone for the assessment of the serology of anti VZV immunity

    Measured: 35 weeks

Secondary outcomes (2)
  1. frequency of immunity detecting depending on whether the patient remember having varicella, have been in contact with next of kin with varicella or been vaccinated against varicella or not

    Measured: up to 35 weeks

  2. Percentage of women accepting the vaccination in case of negative history

    Measured: day during the first visit

Questions about this trial

What is this clinical trial studying?

A study testing Serological Test s for the Virus Chicken Pox Virus in people with Pregnancy, run by Hopital Foch at 1 site in France.

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 3 inclusion and 3 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: stopped early, as of the sponsor's last update on 25 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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 was stopped early (reason given: Low inclusion rate.). Results are not available in the source record.

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?

Rate sensitivity and specificity in negative and dubious zone for the assessment of the serology of anti VZV immunity (time frame: 35 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02775422, which also lists 25 linked publications.

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.
