Trial summary

We are interested in developing new and better ways of diagnosing the cause of lower respiratory tract infections including pneumonia. Currently we find the causal bug (bacteria or virus) in less than 50% of patients with pneumonia. Read more about this study

About this study

Official title: A Study of Pneumococcal Carriage in Hospitalised Patients With Lower Respiratory Tract Infections

We are interested in developing new and better ways of diagnosing the cause of lower respiratory tract infections including pneumonia. Currently we find the causal bug (bacteria or virus) in less than 50% of patients with pneumonia. A potential way to better find the bug responsible may include checking for bugs in the nose by a nasal wash or swab. Better diagnostics would allow more targeted antibiotic therapy and in the future this technique may be used as a way of checking the efficiency of new vaccines.

We are recruiting both patients with respiratory infections and also a 'control' group of patients admitted to hospital who do not have respiratory infection. We need to have access to your medical history information to make sure you are eligible and suitable for the study. If you participate in the study, it is important that the study doctors continue to have access to your personal Investigator Designation Contact telephone Dr Andrea Collins PhD student/research SpR xxxxxxxxxxxxx Carole Hancock Research nurse 0151 706 4856 Prof Stephen Gordon Principle Investigator 0151 705 3169 NW PIL V1.3: October 2012 REC ref: 12/NW/0713 information so you can be followed up properly and so we can contact you during the study if needed.

Patients in both groups will have a nasal wash (or swab), blood (30mls = 6 teaspoons) and urine taken on the day of recruitment and a nasal wash (or swab) and blood (30mls = 6 teaspoons) taken 6 weeks later (this is likely to be as an out-patient at the Royal Liverpool, in extreme circumstances this will occur at the patient's home).

STUDY DESIGN OVERVIEW

Overall research aim

To analyse pneumococcal carriage rates in patients hospitalised with LRTI.

Primary endpoint

Rate of pneumococcal carriage in patients hospitalised with LRTI and age matched controls.

Secondary endpoints

  1. Density of pneumococcal carriage in patients hospitalised with LRTI and age matched controls
  2. Alterations of T cell function (Th1, Th17, T regs) in LRTI patients and age matched controls (versus younger adults as part of our existing 'P4' study).

Study design Patients hospitalised with LRTI between November 2012 and April 2014 will be approached within 72 hours of admission.

Patients recruited into the study will consist of those hospitalised with LRTI and a control group of age matched patients (within +/- 10 years) hospitalised for reasons other than respiratory infection.

What is being measured

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

  1. Rate of pneumococcal carriage in patients hospitalised with LRTI and age matched controls.

    Pneumococcal colonisation will be defined based on the culture (+/-PCR) result of nasal wash/NPS taken at day 0 and 6 weeks.

    Measured: 6weeks

Secondary outcomes (1)
  1. Density of pneumococcal carriage in patients hospitalised with LRTI and age matched controls

    Density will be determined using a modified version of Miles and Misra dilutions.

    Measured: 6weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Lower Respiratory Tract Infections, run by Liverpool University Hospitals NHS Foundation Trust at 1 site in United Kingdom.

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 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 9 Jun 2022. 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 United Kingdom. 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?

Rate of pneumococcal carriage in patients hospitalised with LRTI and age matched controls. (time frame: 6weeks). 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 NCT01861184, which also lists 1 linked publication.

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 9 Jun 2022.
