Active Comparator: Pioglitazone
half of the diabetic patients will be randomized to pioglitazone treatment for 6 months starting out with 15mg qd for 4 weeks and dose increased to 30mg (2 tablets) qday if no adverse effects noted at the four week mark by study physician.
6 month treatment with pioglitazone 15mg for four weeks with dose increased to 30mg if no adverse effects (swelling of lower extremities, liver enzyme elevation) noted at the four week mark.
Other Name: Actos
Placebo Comparator: Placebo
The other half will be randomized to placebo for 6 months. The placebo pills also start out with one "15mg) pill qday and are increased to 2 tablets ("30mg") qday after 4 weeks if no adverse effects are noted by study physician.
The placebo pills also start out with one ("15mg") pill qday and are increased to 2 tablets ("30mg") qday after 4 weeks if no adverse effects are noted by study physician.
- Percent Change in Number of Osteoblast and Adipocyte Colony Forming Units Cultured From Bone Marrow Stem Cells Harvested 6 Months After Treatment With Study Drug Compared to Baseline [ Time Frame: 6 months ]To determine the effect of PIO (pioglitazone) on BMSC (bone marrow stem cell) lineage choice in vivo, a bone marrow aspiration was obtained from patients at baseline and after 6 months of treatment with PIO or placebo. The bone marrow was used for ex vivo CFU-OB (Colony forming units-Osteoblast) and CFU-AD assays using the same protocol described for the in vitro studies previously. We also analyzed the number of total colonies per patient at both baseline and final visit.
- βCTX (Carboxy Terminal Collagen Crosslinks), Osteocalcin, and Adiponectin. [ Time Frame: 6 months ]
- Bone Mineral Density [ Time Frame: 6 months ]
