Study summary

Type 1 diabetes (T1D) is characterized by a progressive destruction of insulin producing beta cells, resulting in a lifelong dependence on exogenous insulin. While beta cells make up less than 1% of the pancreas, studies have demonstrated that T1D is associated with a marked reduction of pancreatic mass at diagnosis and as the disease progresses. As such, if pancreatic volume assessment, by ultrasonography (US) or MRI (Magnetic Resonance Imaging), could be utilized as a marker of beta cell function in high risk patients, non-invasive pancreatic imaging could become an important part of staging diabetes risk. As such, the primary goal of this study is to measure pancreatic volume and compare differences in volume between new onset T1D patients, antibody positive subjects at risk for diabetes, antibody negative individuals, and healthy controls.

Read the detailed description

Participants will have blood tests and two imaging tests. The blood tests will tell us how well the pancreas is working. The imaging tests will measure the volume of the pancreas. There is one study visit associated with this study.

Blood will be drawn for 5 different blood tests. The participant cannot eat or drink for about 8 hours before the blood test (water is allowed). The blood will be sent to a lab. The amount of blood taken is equal to about 1 table spoon. Here are the blood tests that will be performed:

  1. C-peptide - is used to measure the insulin being made by the cells in the pancreas.
  2. Hemoglobin A1c (HbA1c) - is a measure of blood sugar control over the last 2 to 3 months.
  3. Serum trypsin - is used to measure exocrine pancreatic function.
  4. Glucose - is used to measure the amount of blood sugar in your body.
  5. Autoantibodies (diabetes related) - are proteins that are made by the body's immune system. They are a sign that the cells in the pancreas that produce insulin could be damaged.

For the imaging procedures the participant cannot eat for at least 8 hours before the imaging procedure (water is okay). Your empty stomach will allow us to picture the pancreas better.

  1. Magnetic resonance imaging (MRI) is a procedure that allows doctors to look inside the body by using a scanner that sends out a strong magnetic field and radio waves but involves no radiation exposure.
  2. Ultrasound (US) is a device that consists of computer and a transducer that is used to scan the body. A transducer is a small hand-held device about the size of a bar of soap that is attached to the scanner by a cord. A lubricating gel is spread on the skin over the area being examined, and then the transducer is pressed firmly against the skin to obtain images.

These imaging tests will allow us to measure the volume of your pancreas. You will not get any sedation for these tests. If you cannot tolerate the MRI, then we will only do the US.

Study population

The new onset will be people that have been diagnosed with T1D for less than one year. The anitbody negative or anitbody positive will be people that have been enrolled in the TrialNet study, Pathway to Prevention. The healthy control will be people from the general population with no history or family history of T1D.

Groups and cohorts

  • New onset of Type 1 Diabetes

    The subjects with new onset of Type 1 Diabetes will have pancreatic volume assessment by ultrasonography (US), Magnetic Resonance Imaging (MRI) and biochemical testing. These test will be compared to the testing from the other groups.

    Procedure: MRI, US, and blood samples

  • Antibody Positive Risk for Diabetes

    The subjects with single or double antibody positive risk for Type 1 Diabetes will have pancreatic volume assessment by ultrasonography (US), Magnetic Resonance Imaging (MRI) and biochemical testing. These test will be compared to the testing from the other groups.

    Procedure: MRI, US, and blood samples

  • Antibody Negative Risk for Diabetes

    The subjects with antibody negative risk for Type 1 Diabetes will have pancreatic volume assessment by ultrasonography (US), Magnetic Resonance Imaging (MRI) and biochemical testing. These test will be compared to the testing from the other groups.

    Procedure: MRI, US, and blood samples

  • Healthy Control

    The subjects has no family history for Type 1 Diabetes. They will have pancreatic volume assessment by ultrasonography (US), Magnetic Resonance Imaging (MRI) and biochemical testing. These test will be compared to the testing from the other groups.

    Procedure: MRI, US, and blood samples

Interventions

  • ProcedureMRI, US, and blood samples

    All groups will have pancreatic volume assessment by ultrasonography (US), Magnetic Resonance Imaging (MRI) and blood samples. These test will be compared to the testing from the other groups.
