Purpose: To evaluate the impact of degenerative changes due to osteoarthritis (OA) at the spine on volumetric bone mineral density (BMD) as measured by volumetric quantitative computed tomography (vQCT). Material and Methods: Eighty‐four elderly women (mean age 73±6 years), comprising 33 with vertebral fractures assessed by radiographs and 51 without vertebral fractures, were studied. Trabecular, cortical, and integral BMD were examined at the spine and hip using a helical CT scanner and were compared to dual X‐ray absorptiometry (DXA) measurements at the same sites. OA changes visible on the radiographs were categorized into two grades according to severity. Differences in BMD measures obtained in the two groups of patients defined by OA grade using the described radiologic methods were compared using analysis of variance. Standardized difference (effect sizes) was also compared between radiologic methods. Results: Spinal trabecular BMD did not differ significantly between OA grade 0 and OA grade 1. Spinal cortical and integral BMD measures showed statistically significant differences, as did the lumbar spine DXA BMD measurement (13%, P = 0.02). The QCT measurements at the hip were also higher in OA 1 subjects. Femoral trabecular BMD was 13–15% higher in OA grade 1 subjects than in OA grade 0 subjects. The cortical BMD measures in the CT_TOT_FEM and CT_TROCH ROI's were also higher in the OA 1 subjects. The integral QCT BMD measures in the hip showed difference between grades OA 1 and 0. The DXA measurements in the neck and trochanter ROI's showed smaller differences (9 and 11%, respectively). There were no statistically significant differences in bone size. Conclusion: There is no evidence supporting that trabecular BMD measurements by QCT are influenced by OA. Instead, degenerative changes have an effect on both cortical and integral QCT, and on DXA at the lumbar spine and the hip. For subjects with established OA, assessment of BMD by volumetric QCT may be suggested.

Aim. To evaluate the state of bone tissue in comparison with calcium balance, to clarify the risk for fracture development in women of different age groups. METHODS. 92 females aged 19 to 89 years were examined clinically with densitometry of lumbar spine and femoral neck and measuring the concentration of total calcium in the blood. RESULTS. In females younger than 50 years decreased bone density according to Z-score was revealed in 30% of cases, among patients with its normal values significant trend to bone rarefaction (-2.0 SD <Z-score ≤-1.5 SD) was registered with the same rate. In the group of females older than 50 years osteopenia was revealed in 46.3% of cases and osteoporosis - in 42.7%, while more significant decrease in bone mineral density was found in the lumbar spine. Past medical history of fractures increased the rate of osteoporosis by 18%. In females older than 50 years compared to younger patients a significant increase of blood calcium concentration was revealed. Besides, statistically significant increase of its level was noted in cases of fractures in the past and osteoporosis. The revealed changes of bone tissue in females below 50 years of age are indicative of increased risk of osteoporosis development in the future. CONCLUSION. High prevalence of osteoporosis and osteopenia is revealed in the examined patients older than 50 years, and bone mineral density parameters were significantly inversely correlated with calcemia; hence, blood calcium level can be one of the criteria of bone tissue state and in combination with other risk factors for osteoporosis should be taken into account during periodic health examination of females older than 50 years.

The purpose of the study was to determine the features of the development of osteoporotic changes in bones in patients with liver fibrosis against the background of non-alcoholic steatohepatosis. Materials and methods. 79 patients with non-alcoholic steatohepatosis and liver fibrosis were examined. 38 surveyed persons were women, 41 were men. The average age of the patients was 42.5±5.8 years. All patients were excluded from comorbidities for inclusion in the study. For female patients, it was imperative to maintain menstrual function. The degree of liver fibrosis was established based on 2D shear wave elastometry in SWE mode. The patients included to study have liver fibrosis F1 - F3 according to METAVIR. Determination of bone mineral density was performed using a DEXXUM T X-ray densitometer by dual energy absorptiometry. Results and discussion. In patients with fibrotic changes in the liver, a decrease in bone mineral density was found in 49.3%. Osteopenia and osteoporosis in women occurred in 47.4%, which was significantly more frequent than among men – 26.8%, p = 0.014. There was a significant relationship between the duration of the presence of steatohepatosis and the incidence of osteoporosis and osteopenia: among patients with a duration of steatohepatosis of less than 7 years, a decrease in bone mineral density was noted in 62.5% of cases, and with a duration of more than 7 years – already in 89.3% of patients (χ2 = 5.5; p = 0.011). Among patients with liver fibrosis F3 METAVIR, a decrease in bone mineral density was observed in 85.7%. Among patients with liver fibrosis F1-2 METAVIR, osteoporosis and osteopenia were found in 46% (p = 0.0008). In patients with METAVIR F3 fibrosis, osteoporotic changes were observed in 85.2% of cases. An isolated decrease in the mineral density of the lumbar spine was diagnosed in 12 (30.7% of patients with a decrease in bone mineral density). In 9 patients (23%), there was a combination of a decrease in mineral density of the spine with a decrease in mineral density of the hip, the mean T score of the vertebrae was -2.5±0.2, the mean T score of the femoral neck was 2.1±0.3. In patients with F1-F2 fibrosis METAVIR, bone mineral density decreased mainly to the level of osteopenia, isolated osteopenia of the lumbar spine was diagnosed in 18 (46%) patients, there was no decrease in hip mineral density in this group of patients, the mean criterion of T vertebrae was 1.5±0.15. Conclusion. Patients with steatohepatosis and hepatic fibrosis are characterized by a high prevalence of osteoporosis and osteopenia. The risk of developing this complication is higher in patients with fibrosis stages F3 METAVIR; the decrease in bone mineral density in patients with steatohepatosis and liver fibrosis is influenced not only by population risk factors, but also by the duration of the presence of steatohepatosis; the severity of liver fibrosis METAVIR affects the localization of changes in the bone tissue. In patients with degrees of fibrosis F1 - F2, trabecular bone tissue is affected, and in patients with degrees of fibrosis F3, trabecular and cortical bone tissue is equally affected
