Biospecimen Retention:   Samples Without DNA

Estimated Enrollment: 30
Study Start Date: September 2007
Study Completion Date: March 2010
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Normal controls without evidence of diabetes or islet specific autoimmunity
Individuals within 6 months of diagnosis with type 1 diabetes
Individuals at high risk for the development of type 1 diabetes
Individuals with longstanding autoimmune diabetes

Detailed Description:
Approximately one million individuals are afflicted with autoimmune Type 1 diabetes mellitus (T1DM) in the United States. This disease results from the autoimmune destruction of the insulin-producing beta-cells of the islets of Langerhans of the pancreas. Initially, diabetes is usually clinically occult with localized pancreatic inflammation characterized by a lymphocytic infiltration of the pancreatic islets, termed insulitis, which leads to beta-cell specific destruction of the islets. This is often followed by the clinically overt phase that ensues when the bulk of beta cells have been destroyed and the pancreas is no longer able to produce sufficient insulin to maintain glycemic control. The purpose of this study is to assess the ability of magnetic resonance imaging with ferumoxtran-10, a functional molecular imaging agent consisting of iron oxide nanoparticles, to detect changes in the pancreas associated with the insulitis of T1DM.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
The study population is to be drawn from the general population, diabetes clinic population, and at risk individuals as previously identified in prior family studies.

Inclusion Criteria:

  • Recent onset type 1 diabetes as defined by clinical diagnosis within the last 6 months and age less than 30 or at least one islet autoantibody marker (GAD, IAA, or IA-2).


  • High risk of pre-type 1 diabetes as defined by first degree family relative with type 1 diabetes and at least one islet autoantibody marker (GAD, IAA, or IA-2).


  • Individuals with established type 1 diabetes of greater than 6 months duration who were under age 30 or at least one islet autoantibody marker positive (GAD, IAA, or IA-2) at time of diagnosis or who currently are GAD or IA-2 autoantibody marker positive.


  • Normal control as defined by no family history of type 1 diabetes and normal tolerance test (tolerance testing to be performed as part of protocol).

Exclusion Criteria:

  • Individuals under 18 years of age
  • Individuals unable or unwilling to give informed consent/HIPAA authorization
  • Individuals who are clinically unstable
  • Individuals with any contraindications to MRI examination, for example, individuals with pacemakers
  • Pregnant or lactating women
  • Individuals with allergies to iron or dextran
  • Individuals with a history of cirrhosis
