Abstract:

AIM: To investigate the changes of bone mineral density (BMD), insulin resistance (IR) and cytokines in type 2 diabetes mellitus (T2DM) patients with primary hypertension. METHODS: 125 patients of T2DM patients with primary hypertension were randomly divided into Gliclazide plus melformin group (treatment group) and Gliclazide group(control group ).BMI, fasting blood glucose(FPG), hemoglobin A1c(HbA1c), fasting insulin(FINS), the index of insulin resistance(HOMA-IR), adiponectin(APN), 1eptin(LEP), tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), insulin-like growth factor-1(IGF-1) and BMD of the lumbar vertebrae 2-4(L2-4)and the left femofal neck were measured and compared.RESULTS:(1)After treatment for 12 weeks,levels of FPG and HbA1c decreased in both groups (P<0.05);BMI decreased compared with before therapy in treatment group (P<0.05).(2)Compared with before therapy and control group,levels of APN, IGF-1 and BMD of the L2-4 and the left femofal neck increased in treatment group(P<0.05),levels of FINS, HOMA-IR, TNF-α and IL-6 decreased(P<0.05);LEP decreased compared with before therapy (P<0.05),but there was no significant difference after therapy between groups(P>0.05).(3)The BMD of the L2-4 and the left femofal neck were positively correlated with the APN and IGF-1,yet negatively correlated with the HOMA-IR, LEP, TNF-α and IL-6. CONCLUSION: Metformin can improve BMD, IR and correct dysfunction of cytokines in T2DM patients with primary hypertension,which may reduce risk of osteoporosis and fracture.
