BackgroundVitamin D supplements are recommended in individuals with vitamin D insufficiency and established osteoporosis to reduce risk of fracture and falling. Active vitamin D metabolites have been found to be more effective for fall prevention than native vitamin D.ObjectivesThe aim of this study was to compare the efficacy of strontium ranelate in combination with alfacalcidol and strontium ranelate alone on bone mineral density (BMD) and fall risk in postmenopausal women with osteoporosis.MethodsA total of 48 women (mean age 62.4 years) with postmenopausal osteoporosis were randomized to strontium ranelate monotherapy 2 g/day (n = 16), strontium ranelate 2 g/day plus alfacalcidol 1 μg (n = 16) or control (n = 16) and followed for 6 months. All women received calcium and vitamin D3 supplements. BMD was measured at the lumbar spine and proximal femora at the beginning and end of therapy. Patients performed functional tests such as the “up and go” and chair rising tests to estimate risk of fall status. Biochemical markers of bone turnover were also assessed.ResultsStatistically significant increases in BMD compared with baseline values and the control group were observed in both strontium ranelate treatment groups. Increases were also statistically significant in the strontium ranelate combination group compared with strontium ranelate alone. Strontium ranelate combination therapy for 6 months improved patients’ ability to perform functional tests as well as increasing the number of women capable of performing the tests. No significant changes were observed in women receiving strontium ranelate monotherapy or in the control group. Serum levels of β-CrossLaps, a marker of bone resorption, were significantly reduced compared with control in both strontium ranelate groups. A significantly greater reduction was observed in the strontium ranelate combination group compared with strontium ranelate alone (24.0 %; P = 0.008). Increases in type 1 procollagen total N-terminal propeptide (TP1NP), a marker of bone formation, reached statistical significance in both strontium ranelate groups compared with baseline.ConclusionStrontium ranelate and alfacalcidol combination therapy improves bone quality, fall risk and markers of bone turnover to a greater extent than strontium ranelate alone in patients with established osteoporosis.

A prospective population-based survey in a region of the Republic of Uzbekistan determined the incidence of fractures at the hip. The hip fracture rates were used to create a FRAX® model to facilitate fracture risk assessment in Uzbekistan. Objective This paper describes the epidemiology of hip fracture in the Republic of Uzbekistan that was used to develop a country-specific FRAX® tool for fracture prediction. Methods During a 1-year (2016/17) prospective population-based survey in the Pap district of the Republic of Uzbekistan, hip fractures were prospectively identified from hospital registers, trauma centres and primary care and community sources. Age-and sex-specific incidence of hip fracture and national mortality rates were incorporated into a FRAX model for Uzbekistan. Fracture probabilities were compared with those from neighbouring Kazakhstan and Kyrgystan. Results Approximately 41% of hip fracture cases did not come to medical attention, and two thirds of patients overall were not admitted to hospital. The incidence of hip fracture applied nationally suggested that the estimated number of hip fractures nationwide in persons over the age of 50 years for 2015 was 16,764 and is predicted to increase more than threefold to 60,272 in 2050. FRAX-based probabilities were higher in Uzbekistan than Kazakhstan or Kyrgystan. Conclusion The FRAX model should enhance accuracy of determining fracture probability among the Uzbek population and help guide decisions about treatment.

Precise population-based data on the osteoporotic hip fracture (HF) rate play an invaluable role in the assessment of burden of osteoporosis as well as in development of the national clinical fracture risk prediction tool (FRAX). Currently, these data in Uzbekistan is unavailable. Aim. To create a system for the all HF detection to calculate their incidence in Uzbekistan, and to assess the general physicians (GP) and primary care nurses role in this system. Materials and methods. Cohort study was carried out in 20112017 in the Pap district of Uzbekistan We had revealed the national trauma care records peculiarities and then organized the prospective study. The trauma care records were monitored. Besides, all medical specialists including GPs, GP nurses and the community leaders were actively involved into the search and verification of non-hospitalized hip fracture patients escaping trauma care statistics. Results. Overall, among HF patients, only 34% were hospitalized, and 26% took outpatient trauma care. Additional 29% of HF patients were found only with the help of GPs. GP nurses in collaboration with the community leaders disclosed additional 11% patients who had been staying at home without any medical care. The annual standardized HF incidence in people older than 40 years enriched 357.7 for women and 190.2 for men per 100 000. Conclusion. Collection of epidemiological information on HF incidence in Uzbekistan was possible only with the help of GPs and GP nurses as key figures of primary care. The obtained epidemiological data will be incorporated into the first created Uzbek national FRAX model to assess the 10-year risk of osteoporotic fracture in clinical practice.
