The purpose of this study is to find out if diabetes damages the blood vessels of adolescents with good diabetes control compared to adolescents with less optimal control.

Type 1 Diabetes Mellitus Coronary Artery Disease

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Prevalence of Oxidative Stress, Endothelial Dysfunction, Increased Carotid Artery Intima-media Thickness (cIMT) and Biomarkers of Vascular Inflammation in Adolescents With Type-1 Diabetes Mellitus (T1DM)

Further study details as provided by Children's Mercy Hospital Kansas City:

Primary Outcome Measures:
  • Determine the impact of glycemic control on vascular oxidative stress/inflammation in adolescents with Type 1 diabetes mellitus [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • To determine the impact of glycemic control and vascular oxidative stress/inflammation on vascular health in adolescents with T1DM [ Time Frame: 1 year ]

Biospecimen Retention:   Samples With DNA
Whole blood

Enrollment: 51
Study Start Date: January 2010
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
HgbA1c <8
Adolescents with HgbA1c < or equal to 8% for the previous 12 months
HgbA1c >10
Adolescents with HgbA1c > or equal to 10% for previous 12 months

Detailed Description:
Many published studies reveal that adult patients with T1DM can have early, silent and more advanced vessel wall thickness than normal subjects. This is influenced by the degree of their blood sugar control. If this is happening in adolescents, we want to know what proportion of adolescent children with type 1 diabetes show signs of early blood vessel damage. We also want to learn if these signs of damage are linked to other factors such as how long someone has had diabetes, blood sugar control or individual differences because of a difference in genetic make-up.
