Brief Summary

The purpose of this study is to validate the method of analysing Positron Emission Tomography (PET) images to assess lung inflammation. Development of novel therapeutic drugs requires a biomarker whic...

Detailed Description

Inflammation plays an important role in a myriad of human diseases. Interstitial Lung Diseases (ILDs) are characterised by widespread inflammation and represent a major burden to the health sector. Im...

Eligibility Criteria

Inclusion

  • For patients with sarcoidosis:
  • Suspected pulmonary sarcoidosis (as determined by referring physician)
  • Requires bronchoscopy, EBUS and BAL (as determined by ILD team at Royal Papworth or Addenbrooke's Hospitals).
  • Male or female ≥ 30 years with a BMI of 17-35kg/m2
  • Consents to additional bronchoscopic evaluation during NHS mandated bronchoscopy, EBUS and BAL.

Exclusion

  • Inability to provide Informed Consent.
  • A cardiovascular event in the last 6 months (i.e. acute coronary syndrome, unstable angina, CABG, PCI, stroke, MI, carotid endarterectomy).
  • Patients with known clinically significant pulmonary diagnoses of COPD, lung fibrosis, interstitial lung disease, or α1-antitrypsin deficiency.

  • Participation in a previous research trial in the last three years which involved exposure to significant ionising radiation (i.e. cumulative research radiation dose \>10 mSv)
  • Pregnancy
  • Women of childbearing potential \[i.e. either postmenopausal or documented hysterectomy and/or bilateral oophorectomy - tubal ligation is not sufficient\].
  • Use of systemic steroids (oral or intravenous) at a dose \> 10mg od of prednisolone or equivalent and/or antibiotics 4 weeks prior to PET/CT scan
  • Any medical history or clinically relevant abnormality that is deemed by the principal investigator and/or medical monitor to make the subject ineligible for inclusion because of a safety concern
  • For healthy volunteers:
  • Inclusion criteria:
  • Age/gender-matched group (Part A only): Male or female ≥ 30 years with a BMI of 17-35kg/m2 inclusive
  • LPS/saline challenge group (Part B only): Male or female ≥ 50 years with a BMI of 17-35kg/m2 inclusive
  • No smoking history
  • Normal predicted spirometry values: FEV1/FVC \> 0.7 and FEV1 \> 80% predicted
  • Healthy as determined by clinical history \& examination by the investigator
  • Exclusion criteria:
  • Inability to provide informed consent
  • Pregnancy
  • Patients with known chronic inflammation conditions such as rheumatoid arthritis, connective tissue disorders and inflammatory bowel disease
  • A significant cardiovascular event in the last 6 months
  • Insulin dependent diabetes mellitus or known impaired glucose tolerance
  • Participation in previous research trial in the last three years which involves exposure to significant ionising radiation (cumulative dose \>10mSv)
  • Use of systemic steroids (oral or intravenous) at a dose \> 10mg od of prednisolone or equivalent and/or antibiotics 4 weeks prior to PET/CT scan
  • Any medical history or clinically relevant abnormality that is deemed by the principal investigator and/or medical monitor to make the subject ineligible for inclusion because of a safety concern
  • Women of childbearing potential
  • Patients with known chronic infections such as HIV or known active tuberculosis.
  • Active smoking history (defined as \> than 1 cigarette per day on a regular basis) over lifetime
  • Known lung and/or respiratory disease or associated symptoms (e.g. dyspnoea, wheeze)
