BONE MINERAL DENSITY AND PROBABILITY OF OSTEOPOROTIC FRACTURES IN WOMEN WITH TYPE II DIABETES MELLITUS.

OBJECTIVE: The aim: To assess bone mineral density and 10-year probability of major osteoporotic and hip fractures using the Ukrainian FRAX® version for postmenopausal women with Type II diabetes mellitus and to determine the need for OP treatment according to the algorithm FRAX and BMD. PATIENTS AND METHODS: Materials and methods: 690 females aged 50-89 years (mean age 67.0±7.7 years) were divided into two groups: Group I (n=345) was made of mostly healthy women, Group II (n=345) - patients with Type II diabetes mellitus. Bone mineral density was measured using dual-energy X-ray absorptiometry, 10-year probability of major osteoporotic and hip fractures was calculated using the Ukrainian FRAX® model. RESULTS: Results: Bone mineral density and 10-year risk of major osteoporotic and hip fractures did not differ depending on the Type II diabetes mellitus presence, however the frequencies of low-energy, vertebral and all previous fractures were higher in Group II. 19% of women with diabetes mellitus and 38% of healthy ones required antiosteoporotic treatment according to dual-energy X-ray absorptiometry and only 8% and 2%, respectively, according to the FRAX. These indices became higher after recalculation of FRAX taking into account bone mineral density, however they were lower in patients with diabetes mellitus compared to the corresponding rate in the Group I (FRAX (high risk) + bone mineral density: 26% and 41%; χ2 = 18.2; p<0.001). CONCLUSION: Conclusions: The use of FRAX in combination with bone mineral density resulted in an increased necessity for antiosteoporotic treatment, indicating the urgency of using both indices for osteoporotic fractures prediction in patients with Type II diabetes mellitus.

Bone mineral density and trabecular bone score in postmenopausal women with knee osteoarthritis and obesity.

OBJECTIVE: The aim of the study was to investigate the relationship between bone mineral density (BMD) of lumbar spine, femoral neck, trabecular bone score (TBS) and body mass index (BMI), in postmenopausal women with knee osteoarthritis (OA). PATIENTS AND METHODS: Materials and methods: The study group comprised 359 postmenopausal women aged 50-89 years. They were divided into 2 groups: I group - 117 postmenopausal women with symptomatic knee OA and II group -242 women with a normal functional activity of knee joints. Analysis of data was performed taking into account their BMD of lumbar spine (L1-L4) and femoral neck, measured by the Dual-energy X-ray absorptiometry (DXA) Hologic (Discovery WI, USA, 2016). TBS of L1-L4 was detected by TBS insight® software (MedImaps, Pessac, France), and BMI classified by World Health Organization (WHO). RESULTS: Results: In postmenopausal women with obesity prevalence of symptomatic knee OA was detected in 41.1% of cases. However, in women with normal BMI knee OA was revealed in 29.0% of women. The highest level of knee OA in obese women aged 70-79 years - 45.8%. According to a chi-squared (χ2) test, a significantly higher level of BMI was detected in postmenopausal women with OA (χ2=5.05, p=0.02). CONCLUSION: Conclusion: Women with a symptomatic OA had a significantly higher BMD of lumbar spine compared with women who had a normal functional activity of knee. Significant negative correlation were detected between TBS and BMI, and significant positive correlations between lumbar spine BMD and BMI.
