Purpose

The UK Medical Research Council (MRC) together with the Association of British Pharmaceutical Industries (ABPI) have recently funded a program designed to foster collaboration between academic COPD researchers and the pharmaceutical industry in the UK, with the aim of developing and furthering our research capacity and expertise for the benefit of patients living with this prevalent and disabling condition. This builds on the strong international track record of COPD research in the UK. The program is divided into four work packages (WP1-4), each with specific aims. WP1 will collate and establish data from patient cohorts and share this information through the development of knowledge management platforms. WP2 will specifically assess how airway micro-organisms impact on COPD and how the effects of bacteria and viruses may be modified. WP3 is concerned with tissue injury and repair which are fundamental processes in the development of COPD. WP4 will examine in detail the potential for improving patient outcomes by targeting the skeletal muscle dysfunction that can profoundly affect exercise capacity.

COPD	Radiation: CT scan and PA chest X-ray


Study Type:	Observational
Study Design:	Observational Model: Cohort Time Perspective: Prospective
Official Title:	The Mechanisms of Inflammation and Immunity in COPD and Their Relationship to Exacerbations and Disease Progression.

Further study details as provided by University College, London:

Biospecimen Retention: Samples With DNA

Blood, sputum and urine samples will be collected. Commercially available ELISA assays will be be used to qualify inflammatory markers.

Quantitative bacterial culture will be performed on sputum samples. Bacterial and viral load will be determined by polymerase chain reaction (PCR). Proteomics such as Cholesterol, BNP, CRP by routine hospital assay techniques. Specific DNA sections will be selected from the genome to identify/confirm genes believed to be associated with different COPD phenotypes by molecular techniques.


Estimated Enrollment:	400
Study Start Date:	February 2011

Groups/Cohorts	Assigned Interventions
COPD, GOLD II severity or above	Radiation: CT scan and PA chest X-ray All participants will receive a single high resolution CT scan of the chest. This will be performed using a low tube current, helical technique. Participants may also receive a plain chest X-ray if clinically indicated. The total research protocol dose is 2 mSv. The dose from the chest X-ray is insignificant compared with the dose from the CT scan of the chest, therefore all this dose can be considered to be additional to standard of care. A dose of 2 mSv represents a risk of radiation induced detriment of approximately 1 in 10,000 and is equivalent to about 11 months of average natural background radiation in the UK.

Eligibility


Ages Eligible for Study:	40 Years and older (Adult, Senior)
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No
Sampling Method:	Non-Probability Sample

Study Population

Patients will be recruited from existing cohorts and may have participated in previously approved studies.

Potential primary care patients will be identified from databases held in practices and contacted, by the GP, by letter in the first instance. If the patient replies to the GP that they are willing to participate in the research, then a telephone call will be made by the research team to arrange a clinic visit.

Potential outpatient participants will be identified by the outpatient respiratory physician and if willing to participate will be referred to the research team via telephone call or referral letter.

Stage IV FEV1 <30% predicetd or <50% predicted and chronic respiratory symptoms
Past or present smokers

Age >40 years at recruitment
Reasonable command of English to complete daily diary cards

Exclusion Criteria:

History of asthma
History of neoplasia
History of other significant respiratory disease
Pregnancy
