Detailed Description:
An increased skeletal fracture risk in diabetes has only recently been recognized. Human studies of patients with diabetes using bone mineral density and bone markers have noted low bone mass and mixed results on remodeling activity. Mouse models of diabetes have suggested that low bone turnover is the underlying problem. Low bone turnover could lead to an accumulation of microdamage that is not repaired causing compromised bone strength. Low bone turnover has not yet been confirmed in humans. This human study is designed to elucidate the effect of Type 1 diabetes on 1) bone remodeling, including histomorphometric and biochemical measures of bone formation and resorption, and 2) on structure, including micro architectural arrangement of trabeculae and bone mineral density.

Ages Eligible for Study:   19 Years to 50 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
males or females who are greater than 19 years of age and less than age 50 who have been diagnosed with type 1 diabetes for over 3 years.

Inclusion Criteria:

  • Age > 19 yrs or < 50 yrs.
  • The diabetic subjects must have a diagnosis of Type 1 diabetes clinically defined as diabetes onset before age 50, acute presentation or diabetic ketoacidosis, with normal BMI. If history is equivocal, GAD antibodies > 1.45 U/mL will be used to define diagnosis.
  • Diabetic subjects must be on insulin treatment.
  • All subjects must have BMI between 18-30

Exclusion Criteria:

  • On any medications that are known to interfere with bone metabolism including loop diuretics, steroids, anticonvulsants, bisphosphonates, metformin, glitazones
  • Have normal or only mildly impaired kidney function defined as a calculated GFR greater than 60 mL/min/1.73m2
  • History of cancer other than skin cancer
  • Unstable angina, myocardial infarction, uncontrolled hypertension, malabsorption, active rheumatoid or collagen disease.
