NCT02286128

Brief Summary

This study determines whether NF-кB dependent proinflammatory state found in type 2 diabetes yield to a higher RAGE activation in the mesenchymal stem cell, as well as the effects of the proinflammation on osteoblast differentiation impairment and cellular apoptosis in type 2 diabetic patients. This study will compare non-diabetic control subjects and type 2 diabetic patients with metformin monotherapy failure in the aspect of 1) serum markers for NF-кB dependent proinflammatory state and its intracellular signals, 2) osteogenic differentiation and apoptosis of the mesenchymal stem cells, and 3) serum AGE, RAGE and cellular RAGE activation.

Outcome Measures

Primary Outcomes (1)

  • Correlation between NF-кB dependent-proinflammation markers and osteoblast-specific gene expression in the MSC to measure the effects of NF-кB dependent-proinflammation on differentiation potential toward osteoblast in type 2 diabetes.

    2-4 weeks

Secondary Outcomes (2)

  • Correlation between NF-кB dependent-proinflammation markers and apoptotic marker expression in the MSC to measure effects of NF-кB dependent-proinflammation on cellular apoptosis in type 2 diabetes.

    2-4 weeks

  • Correlation between NF-кB dependent-proinflammation markers and the expression of RAGE and its downstream signals in the MSC to measure effects of NF-кB dependent-proinflammation on cellular RAGE activation in type 2 diabetes.

    2-4 weeks

Study Arms (2)

Non-diabetic controls

Age-matched non-diabetic subjects

Type 2 diabetes

Type 2 diabetes with metformin monotherapy failure

Study Population

This study will include 30 non-diabetic control subjects, and 45 type 2 diabetic patients who has HbA1c higher than 6.5% with metformin monotherapy.

You may qualify if:

  • Patients with type 2 diabetes who has HbA1c higher than 6.5% with metformin monotherapy and age-matched non-diabetes control subjects who signed consent form to be in the study.

You may not qualify if:

  • Patients who use thiazolidinedione, steroid, immunosuppressive medications, antiresorptive agents or anabolic therapy for osteoporosis.
  • Patients with elevated serum creatinine higher than 1.4 in female and 1.5 in male.
  • Patients with metastases cancer or hematologic malignancy.
