Background. Osteoporosis and type 2 diabetes are common comorbidities in postmenopausal women. An important role in the bone remodeling over the menopausal transition can be played by cytokines and matrix metalloproteinases (MMPs). It was shown that allelic variants in polymorphic positions of the genes of cytokines and MMPs affect the expression of these molecules under normal and pathological conditions. Aims. To examine associations between polymorphisms in the gene promoters of cytokines (TNFA, IL1B, IL4, IL6, IL10, VEGFA) and MMPs (MMP2, MMP3, MMP9) with bone mineral density (BMD) in postmenopausal women with type 2 diabetes. Materials and methods. We studied 197 Caucasian diabetic women, from 50 to70 years of age. An examination of BMD in the spine, proximal femur and forearm was performed by DEXA. Thirteen polymorphisms in the promoters of TNFA: -238 A/G (rs361525), -308 A/G(rs1800629) and -863 C/A (rs1800630), IL1B: -31 C/T (rs1143627), IL4: -590 C/T (rs2243250), IL6: -174 C/G (rs1800795), IL10: -592 C/A (rs1800872) and -1082 A/G (rs1800896), VEGFA: -2578 C/A (rs699947) and +936 C/T (rs3025039), MMP2: -1306 C/T (rs243865), MMP3: -1171 5A/6A (rs3025058) and MMP9: -1562 C/T (rs3918242), were investigated. Results. Seventy-three women had normal BMD, in 90 ones we revealed osteopenia, and 34 women had osteoporosis. Age, BMI and smoking were strongest predictors of BMD in multivariate regression analysis (p0.0001, p=0.003 and p=0.01, respectively). In the additive model, C allele and CC genotype in MMP9 -1562 position were associated with low BMD (OR 2.16, p=0.0007 and OR 2.02, p=0.0008, respectively). Association of the polymorphism with BMD remained significant after adjustment for clinical risk factors (p0.001). Twelve combinations of genotypes, associated positively with low BMD, were revealed by bioinformatic analysis (all p0.005). The СС genotype in position -1562 of MMP9, CC genotype in position -863 of TNFA, GG genotype in position -308 of TNFA, and AA genotype in position -1082 of IL10 were the most prevalent variants in these combinations. Conclusions. Variability in the gene promoters of cytokines and MMPs may confer individual susceptibility to osteoporosis in postmenopausal type 2 diabetic women.

Osteoporosis Fracture

Abstract AMI: There is growing evidence of a complex interaction between T2DM and osteoporosis. The purpose of this study was to further study the relationship between BTMs and fasting blood glucose (FBG) in postmenopausal patients with type 2 diabetes and to analyze the effect of hyperglycemia on bone metabolism. Methods: Six hundred and twelve (612) postmenopausal women were included, including one hundred and seven (107) subjects with T2DM and five hundred and five (505) subjects without diabetes. BMD was measured by DXA (dual-energy X-ray absorptiometry). Markers of bone formation (P1NP) and resorption ( CTX ) were quantified. Results: Compared to controls, postmenopausal women with diabetes had a higher prevalence of previous osteoporosis fracture (27.1% vs. 17.4% for diabetic and nondiabetic women, respectively) and a higher BMD. The P1NP level in women with T2DM was 49.451 ng/ml, while in N-DM individuals, it was 58.633 ng/ml, (p = 0.017). The CTX level in women with T2DM was 0.325 ng/ml, while in N-DM individuals, it was 0.412 ng/ml (p=0.039). In addition, P1NP was significantly negatively associated with age (β=-0.590; p= 0.002) and FBG (β=-1.950; p = 0.035). CTX was negatively associated with FBG (β=-0.029; p = 0.015). Conclusions: T2DM was associated with higher BMD and paradoxically, with an increased risk of fracture. Postmenopausal women with T2DM had lower bone turnover than controls. With increased levels of FBG, bone formation and bone resorption were reduced, and the overall bone turnover level was reduced.

The Impact

Abstract The aim of this study was to evaluate the impact of a community-based exercise program on bone mineral density and body composition in postmenopausal women with pre-diabetes and type 2 diabetes. Twenty postmenopausal women (aged 61.3 ± 6.0 years) with pre-diabetes and type 2 diabetes were randomly assigned to a community-based exercise program group (n=10) or a control group (n=10). The community-based exercise program was multicomponent, three days per week for 32 weeks, and included walking, resistance and aquatic exercises. Body composition and bone mineral density were measured pre and post-training by dual X-ray absorptiometry. In the exercise group significant increases were found in the ward’s triangle bone mineral density (+7.8%, p=0.043), and in fat-free mass (+2.4%, p=0.018). The findings suggest that regular multicomponent training is effective in preventing osteoporosis and sarcopenia among postmenopausal women with pre-diabetes and type 2 diabetes.
