Lower Respiratory Tract Infections Clinical Trial
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. ;
