About this study

Official title: Antibody Titer Analysis Afer Monovalent Vaccination in Pediatric Haemato-oncology Patients

The patients of pediatric haemato-oncology have a higher risk for novel H1N1 influenza infection than general population, and they are strongly recommended to receive novel H1N1 vaccination. However, there is no previous data to answer how the efficacy and effectiveness of novel H1N1 vaccination is in patients of pediatric haemato-oncology. This study is designed to investigate the antibodies titers before and after the novel H1N1 influenza vaccination in these patients. Titer of H1N1 influenza virus antibodies will be determined by hemagglutinin inhibition assay (HAI). A HAI titer with a 4-fold rise or greater is defined as seroconversion. Study subjects with seroconversion are regarded as responsiveness to the vaccination. Meanwhile, if the patient presents influenza-like symptoms, we will perform throat swab or nasal swab for influenza rapid test, viral isolation, and novel H1N1 influenza PCR to confirm the diagnosis. After the study, we will be able to know whether or not current novel H1N1 influenza vaccination schedule is adequate and efficient for pediatric haemato-oncology patients.

Read the detailed description

The emergence of novel H1N1 influenza in 2009 has a great impact to the societies in Taiwan and worldwide. The patients of pediatric haemato-oncology have a higher risk for novel H1N1 influenza infection than general population, and they are strongly recommended to receive novel H1N1 vaccination. However, there is no previous data to answer how the efficacy and effectiveness of novel H1N1 vaccination is in patients of pediatric haemato-oncology. This study is designed to investigate the antibodies titers before and after the novel H1N1 influenza vaccination in these patients. Thus two blood samples will be drawn. The first sample will be collected before the vaccination and the second one will be collected three weeks after the vaccination (If the patient is younger than 9 years old, the third sample will be collected three weeks after the booster vaccination). Titer of H1N1 influenza virus antibodies will be determined by hemagglutinin inhibition assay (HAI). A HAI titer with a 4-fold rise or greater is defined as seroconversion. Study subjects with seroconversion are regarded as responsiveness to the vaccination. We will analyze seroconversion rate as well. Meanwhile, if the patient presents influenza-like symptoms, we will perform throat swab or nasal swab for influenza rapid test, viral isolation, and novel H1N1 influenza PCR to confirm the diagnosis. After the study, we will be able to know whether or not current novel H1N1 influenza vaccination schedule is adequate and efficient for pediatric haemato-oncology patients.

What is being measured

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

  1. This study is designed to investigate the antibodies titers before and after the novel H1N1 influenza vaccination in these patients. Titer of H1N1 influenza virus antibodies will be determined by hemagglutinin inhibition assay (HAI).

    Measured: Dec, 2009 - Feb, 2010

Secondary outcomes (1)
  1. If the patient presents influenza-like symptoms during the six month follow up period, we will perform throat swab or nasal swab for influenza rapid test, viral isolation, and novel H1N1 influenza PCR to confirm the diagnosis.

    Measured: Dec, 2009 - Jun, 2010

Questions about this trial

What is this clinical trial studying?

An observational study of Serology Analysis and Novel H1N1 Influenza Vaccination, run by National Taiwan University Hospital at 1 site in Taiwan.

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 4 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 11 Jan 2010. 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 Taiwan. 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?

Results are not available in the source record.

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

Contact Luan-Yin Chang, MD (886-23123456 ext. 75128, ly7077@tpts6.seed.net.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

This study is designed to investigate the antibodies titers before and after the novel H1N1 influenza vaccination in these patients. Titer of H1N1 influenza virus antibodies will be determined by hemagglutinin inhibition assay (HAI). (time frame: Dec, 2009 - Feb, 2010). 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 11 Jan 2010.
