Primary Outcome Measures:
  • Develop sensitive, specific, and quantitative methylation- specific PCR assays for the detection of human beta cell-specific DNA methylation patterns cells and the onset of metabolic dysregulation. [ Time Frame: 1 year post diagnosis ]
  • Use the assays to detect beta cell destruction throughout the early time-course of type 1 diabetes mellitus [ Time Frame: 1 year post diagnosis ]

Enrollment: 6
Study Start Date: July 2009
Study Completion Date: April 2015
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
25 newly diagnosed Type 1 diabetics
25 newly diagnosed Type 1 diabetics within onset of symptoms
Procedure: Blood draw
Blood draw for Type I DM patients will be taken every 4 weeks for 1 year post diagnosis/healthy volunteers will have 1 blood draw
25 healthy volunteers
25 healthy volunteers (age & sex matched)
Procedure: Blood draw
Blood draw for Type I DM patients will be taken every 4 weeks for 1 year post diagnosis/healthy volunteers will have 1 blood draw

Detailed Description:
The study will follow 25 newly diagnosed type 1 diabetic patients from the onset of symptoms to one year post-diagnosis. A total of 11 fasting blood draws will be taken, the first near the time of diabetes diagnosis, then 2 weeks later, monthly for the next 6 months, and every other month until 12 months. Each blood sample will be evaluated by the MSP assay, as well as for measurement of fasting plasma glucose, HbA1c, c-peptide, and autoantibodies. The study will also need 25 healthy volunteers to help us match some DNA markers needed for this data. Healthy volunteers will be se=matched healthy individuals who have one blood sample drawn.
