Trial summary

Otitis Media (OM) is one of the most frequent diseases in childhood and the primary reason for children to visit a physician. In many countries it is the most common reason to prescribe antibiotics leading to increased drug-resistance of the causative agents, or to undergo surgery. Read more about this study

About this study

Official title: Thorough Clinical Investigation of the Host-pathogen Interaction in Chronic and Recurrent Otitis Media

Otitis Media (OM) is one of the most frequent diseases in childhood and the primary reason for children to visit a physician. In many countries it is the most common reason to prescribe antibiotics leading to increased drug-resistance of the causative agents, or to undergo surgery. Costs for general health care are expanding, and are estimated to be 3-5 billion dollar annually in the United States. Prevention is suspected to be an important solution to this problem.

Although OM management has no universal standard yet, it may imply watchful waiting, antibiotic treatment, adenoidectomy, insertion of tympanostomy tubes and (future) vaccination. Approximately 80% of the acute otitis media (AOM) cases is self-limiting within 2-14 days and also otitis media with effusion (OME) resolves spontaneously: 60% of newly detected OME resolves within 3 months. However, in a significant part of the OM population persistent or recurrent episodes of OM are responsible for a significant morbidity for both children and parents, despite variable treatment options.

Through the set up of a new prospective cohort in a clinical setting, relevant patient characteristics, the role of bacterial and viral pathogens, the role of recurrent infection in relation to biofilm formation, and the host response at protein level will be studied in detail. This project is expected to increase the understanding of the underlying mechanisms of OM disease, which will support future treatment and prevention strategies. Better understanding in OM pathogenesis is warranted in order to develop these novel preventive strategies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • questionnaireOther

    Identification of risk factors

  • blood sampleProcedure or surgery

    venal puncture, 5ml. A blood sample will be taken at the day of surgery and after 2-3 months.

  • collection of middle ear fluidProcedure or surgery

    During routine surgery middle ear fluids are collected per patient.

  • nasopharyngeal swabProcedure or surgery

    A nasopharyngeal swab is taken at the end of the surgical procedure and after 2-3 months.

What is being measured

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

  1. Detection of biological markers in blood which inform us about the risk of recurrent infection and severity of disease

    Measured: 01-06-2009 to 01-06-2010

Secondary outcomes (4)
  1. Otitis media demography

    Measured: 15-04-2008 to 01-01-2010

  2. Bacterial and viral pathogen detection

    Measured: 15-04-2008 to 01-01-2010

  3. Determination of the molecular and cellular immune response in relation to viral and bacterial pathogens

    Measured: 15-04-08 to 01-01-2010

  4. Gene expression profiling of the three major bacterial pathogens: S. pneumoniae, H. influenzae and M. catarrhalis

    Measured: 01-06-2009 to 01-06-2010

Questions about this trial

What is this clinical trial studying?

An observational study of Otitis Media, run by Radboud University Medical Center at 2 sites in Netherlands.

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 4 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 20 Jul 2011. 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 Netherlands. 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?

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?

Detection of biological markers in blood which inform us about the risk of recurrent infection and severity of disease (time frame: 01-06-2009 to 01-06-2010). 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 20 Jul 2011.
