Brief Summary:

Inflammatory Bowel Diseases (IBD) is a group of relapsing and remitting gut inflammatory conditions acquired due to genetic susceptibility and/or environmental triggers. The disease manifestations are being increasingly seen in young children and the life-long debilitation has a severe effect on quality of life. Limited evidence suggests, although rare, in some young IBD individuals vascular complications may ensue. This leads to increased risk of vascular problems such as thrombosis, arterial disease and stroke.

In the present project we aim to study and highlight potential vascular changes in young Inflammatory Bowel Disease (IBD) patients and compare these changes with age and gender matched controls. Vasculature will be measured in multiple ways including blood analysis in the laboratory and non-invasive, physiological measures of arterial health (e.g. ultrasound arterial scan). Our overall goal is to identify biomarkers indicative of increased risk of vascular dysfunction as this will open new avenues for early therapeutic intervention.

Primary Outcome Measures :
  1. Carotid-Femoral Pulse Wave Velocity (PWV) [ Time Frame: Once, upon recruitment ]
    Pulse wave velocity is a measure of arterial stiffness, and correlates with cardiovascular events and all-cause mortality.

Secondary Outcome Measures :
  1. Plasma Microparticle (MP) number [ Time Frame: Once, upon recruitment ]
    Plasma microparticles will be isolated and enumerated by flow cytometry

  2. Carotid Intima Media Thickness [ Time Frame: Once, upon recruitment ]
    The thickness of the carotid tunica intima and tunica media will be assessed by ultrasound. This thickness correlates with atherosclerosis.

  3. Plasma Microparticle (MP) pro-thrombotic potential [ Time Frame: Once, upon recruitment ]
    Plasma microparticles will be isolated and their pro-thrombotic potential will be assessed by calibrated automated thrombogram (CAT).

  4. Circulating endothelial cells (CEC)s enumeration [ Time Frame: Once, upon recruitment ]
    Circulating endothelial cells enumerated from whole blood, as a marker for endothelial dysfunction.

  5. Plasma C-reactive protein (CRP) level [ Time Frame: Once, upon recruitment ]
  6. Plasma serum amyloid A (SAA) level [ Time Frame: Once, upon recruitment ]
  7. Plasma Tumour Necrosis Factor Alpha (TNF-a) level [ Time Frame: Once, upon recruitment ]
  8. Plasma interleukin 1 alpha (IL-1a) level [ Time Frame: Once, upon recruitment ]
  9. Plasma interleukin 1 beta (IL-1b) level [ Time Frame: Once, upon recruitment ]
  10. Plasma interleukin 6 (IL-6) level [ Time Frame: Once, upon recruitment ]
  11. Plasma Monocyte Chemotactic Protein 1 (MCP-1) level [ Time Frame: Once, upon recruitment ]
  12. Plasma Vascular Endothelial Growth Factor (VEGF) level [ Time Frame: Once, upon recruitment ]
  13. Plasma fasting lipid levels [ Time Frame: Once, upon recruitment ]
  14. Plasma angiopoietin 1/2 levels [ Time Frame: Once, upon recruitment ]
  15. Erythrocyte Sedimentation Rate [ Time Frame: Once, upon recruitment ]
  16. Plasma D-dimer level [ Time Frame: Once, upon recruitment ]

Ages Eligible for Study:   8 Years to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Patients will be identified by the Clinical Nurse Specialists (CNS's) for Inflammatory Bowel Disease (IBD), on-call Gastroenterology registrars and consultants as well as the Pre-admission Nurses (PAN) within Great Ormond Street Hospital (GOSH). The lead consultants for IBD would also alert us of suitable patients for the study, as well as any suitable patients attending their regular gastroenterology clinics.

Inclusion Criteria:

  • Clinical diagnosis of Inflammatory bowel disease (IBD arm)
  • Aged between 8 years and 18 years at recruitment (both arms)

Exclusion Criteria:

  • Clinical diagnosis of Inflammatory Bowel Disease (Control arm)
  • Diagnosis of any other chronic inflammatory condition
