Cord Blood Plus Vitamin D and Omega 3s in T1D

Summary

In this pilot study the investigators are trying to see if a single intravenous infusion of autologous (self) cord blood cells followed by 1 year of daily vitamin D and omega 3 fatty acid supplementation can preserve beta cell function (prolong "honeymoon") in children with type 1 diabetes. All subjects will continue to use insulin therapy as needed to maintain the best possible glucose control.

15 Subjects will be randomized such that 2 of every 3 (10 total) will receive cord blood plus vitamin D and Omega 3 while 1 of 3 (5 total) will serve as controls and will not receive cord blood, vitamin D, or Omega 3 supplementation.

The study will involve 5 visits over 1 year to the University of Florida

This study is a follow-up to our initial study of cord blood infusion alone in which 23 children received autologous cord blood. The initial study was 100% safe but additional studies like the one described above are needed to determine how to improve cord blood based therapy.

Conditions

• Type 1 Diabetes

Interventions

BIOLOGICAL

Autologous UCB

Umbilical Cord Blood stem cells CAN be collected and frozen immediately after birth in private and public cord blood banks. If a child with recent onset T1D has their OWN cord blood in storage they may qualify for this study. The cells would be released to the University of Florida where we would perform a single IV infusion of the cells once they have been thawed and washed. Depending on how the cells are stored, it may be possible to keep some portion of the cells in storage for future use.

DIETARY_SUPPLEMENT

Omega 3 FA

Omega 3 Fatty Acids commonly found in fish oil may play an important role in preserving beta cell function via their anti-inflammatory actions. Those subjects randomized to treatment will take a daily supplement supplied as a capsule that can either be swallowed whole or opened so the contents can be mixed with food.

DIETARY_SUPPLEMENT

Vitamin D

Vitamin D is important for calcium absorption and bone health but may also play an important role in promoting healthy immune responses. Subjects randomized to intervention will take vitamin D supplied as a liquid in a dropper (1 drop per day added to food) for 1 year.
