Active Comparator: Type 1 Diabetics
All participants will complete 4 visits over 6-8 weeks. Visit 1 is a screening visit which includes a physical exam, a bone mineral density scan, a blood draw and an EKG. Visit 2 consists of dispensing the Tetracycline antibiotic required for the bone biopsy. Visit 3 is the bone biopsy and includes a blood draw. Visit 4 is to remove the stitches.
Procedure: Transilial bone biopsy
The transiliac bone biopsy will be performed on each subject under local anesthesia, and conscious sedation. From one skin incision located ~2cm posterior and inferior to the anterior-superior pelvic spine on one side of the pelvis, the investigators will obtain two iliac bone specimens, each 7.5 mm in diameter, cylindrical in shape, and including both inner and outer cortices and the intervening trabecular bone.
