Objective: The role of osteoprotegerin (OPG) and its receptor activator of nuclear factor κB legend (RANKL) in the regulation of bone in humans remain unclear. We examined the sex-specific associations of serum OPG, RANKL, and their ratio with bone mineral density (BMD) in older adults. Design: Participants were 681 community-dwelling adults, ages 45–90 years, who had serum OPG and RANKL measured and bone density scans in 1988–1991, with follow-up scans 5 and/or 10 years later. Methods: Analyses were sex-specific; women using and not using estrogen were evaluated separately. Cross-sectional analyses used multivariable regression models; longitudinal analyses used repeated measures mixed effects models. Results: In cross-sectional analyses, age- and weight-adjusted serum OPG levels were significantly positively associated with BMD at the lumbar spine in men, and at the femoral neck, total hip, and lumbar spine in women using estrogen, but not in non-users of estrogen. RANKL concentrations were significantly and inversely associated with BMD in men only, and at the total hip. Neither OPG nor RANKL was significantly associated with bone loss. Results for the RANKL/OPG ratio were the same as those for RANKL alone. Conclusions: These results suggest a modulatory effect of both endogenous and exogenous sex hormones on the biologic interaction of OPG, RANKL, and bone.

Objective.To evaluate the association between circulating leptin and bone mineral density (BMD) in patients with rheumatoid arthritis (RA).Methods.One-hundred thirty postmenopausal women with RA were assessed for body mass index (BMI), disease characteristics, history of drug use, rheumatoid factor, and erythrocyte sedimentation rate (ESR). BMD (g/cm2) was determined in the hip and spine by DEXA. Serum leptin concentrations were measured by ELISA. Spearman’s correlation coefficients (rho) were determined between BMD and leptin and other variables. A multiple regression analysis was used to adjust for confounders.Results.Patients’ serum leptin levels varied widely (range 2–128 ng/ml). Thirty-three patients (25%) had osteoporosis. Higher levels of leptin correlated significantly with BMD in the lumbar spine (rho = 0.17, p = 0.04) and total hip (rho = 0.21, p = 0.01). The variables that were negatively correlated with BMD were age, duration of menopause, and ESR. After adjustment for confounders, leptin was no longer associated with BMD. In the multivariate model, factors that remained associated with BMD in the total hip were age (p = 0.021) and BMI (p = 0.003); and the factors that remained associated with BMD in the lumbar spine were BMI (p = 0.03) and ESR (p = 0.01).Conclusion.No relevant association was found between circulating leptin levels and BMD in patients with RA in this cross-sectional study. Followup studies are needed to evaluate whether abnormal leptin levels confer a risk for fractures due to osteoporosis.

ABSTRACTBackgroundThe effect of long-term inhaled corticosteroid (ICS) therapy on the bone health of older adults remains unclear due to its possible impact on bone mineral density (BMD).ObjectiveTo evaluate, cross-sectionally and longitudinally, the impact of ICS use on BMD in postmenopausal women with asthma or chronic obstructive pulmonary disease (COPD).MethodsWe used a population-based bone densitometry registry linked with administrative health data of the province of Manitoba, Canada (1999–2013), to identify women with diagnosed asthma or COPD. ICS use was defined as cumulative dispensed days prior to baseline BMD (cross-sectional analysis), and medication possession ratio (MPR) between two BMD measurements (longitudinal analysis). Results were adjusted for multiple covariates including the underlying respiratory diagnosis and its severity.ResultsIn the cross sectional analysis, compared with non-users, women with the highest tertile of prior ICS exposure had lower baseline BMD at the femoral neck (-0.09 standard deviations [SD] below a healthy young adult, 95% CI: −0.16, −0.02) and total hip (-0.14 SD, 95% CI: −0.22, −0.05), but not at the lumbar spine. Longitudinally, the highest tertile of ICS exposure was associated with a slight decline in total hip BMD relative to non-users (-0.02 SD/year, 95% CI: −0.04, −0.01), with no significant effect at the femoral neck and lumbar spine. Middle and lower tertiles of ICS use had no significant effects.ConclusionHigh exposure to ICS was associated with a small adverse effect on baseline hip BMD and total hip BMD loss in post-menopausal women with asthma or COPD.

Abstract Background Despite the increased fracture risk, bone mineral density (BMD) is variable in type 1 (T1D) and type 2 (T2D) diabetes mellitus. We aimed at comparing independent BMD predictors in T1D, T2D and control subjects, respectively. Methods Cross-sectional case-control study enrolling 30 T1D, 39 T2D and 69 age, sex and body mass index (BMI) – matched controls that underwent clinical examination, dual-energy X-ray absorptiometry (BMD at the lumbar spine and femoral neck) and serum determination of HbA1c and parameters of calcium and phosphate metabolism. Results T2D patients had similar BMD compared to T1D individuals (after adjusting for age, BMI and disease duration) and to matched controls, respectively. In multiple regression analysis, diabetes duration – but not HbA1c- negatively predicted femoral neck BMD in T1D (β= -0.39, p = 0.014), while BMI was a positive predictor for lumbar spine (β = 0.46, p = 0.006) and femoral neck BMD (β = 0.44, p = 0.007) in T2D, besides gender influence. Age negatively predicted BMD in controls, but not in patients with diabetes. Conclusions Long-standing diabetes and female gender particularly increase the risk for low bone mass in T1D. An increased body weight partially hinders BMD loss in T2D. The impact of age appears to be surpassed by that of other bone regulating factors in both T1D and T2D patients.

Abstract Background The relationship between renal function and bone mineral density (BMD) is controversial. The aim of this study was to determine the relationship of renal function with BMD and osteoporosis risk in healthy postmenopausal Chinese women. Methods A cross-sectional study was conducted in 776 healthy postmenopausal Chinese women. Dual-energy X-ray absorptiometry was used to measure BMDs. Clinical, demographic, and biochemical data were obtained at the time of image acquisition. Estimated glomerular filtration rate (eGFR) was calculated using a Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Results Women with eGFR levels of at least 90 ml/min/1.73m2 had a lower prevalence of osteoporosis compared with women with decreased eGFR levels (60 ml/min/1.73 m2 ≤ eGFR < 90.0 ml/min/1.73 m2). BMDs at femoral neck and total hip were significantly lower in the lower eGFR class than the higher class (0.717 ± 0.106 vs 0.744 ± 0.125 g/cm2, P < 0.01; 0.796 ± 0.116 vs 0.823 ± 0.129 g/cm2, P < 0.01, respectively). eGFR was positively correlated with BMDs at femoral neck and total hip in unadjusted analysis (P < 0.05). After controlling for age, menopausal duration and body mass index (BMI), decreased eGFR was not associated with osteoporosis risk. Conclusions After adjustments for age, menopausal duration and BMI, the decline in renal function was not independently associated with osteoporosis risk in healthy postmenopausal Chinese women.

Objectives: Although Dual-energy X-ray Absorptiometry (DXA) is gold standard for osteoporosis diagnosis, several reports have shown discordant T-score values measured by Quantitative Computed Tomography (QCT) and DXA especially in obese subjects, but it is still not clear whether BMD measurement by two modalities is affected by overall obesity or central obesity in postmenopausal females. Therefore, the aims of this study were to compare BMD and T-scores by DXA and QCT and to evaluate whether these two osteoporosis assessment modalities yield different T-score values in postmenopausal females with obesity and central obesity. Methods: This cross-sectional study enrolled 44 postmenopausal females, referred for osteoporosis screening. Anthropometric indices (BMI-body mass index, WC-waist circumference and ICOindex of central obesity) were measured and females underwent an assessment of bone mineral density by DXA and QCT. Results: Lumbar Spine (LS) T-score values were observed to be significantly lower by DXA compared to qCT in females with BMI >25 kg/m2, (-1.9±1.5 vs. -2.3±1.2; p=0.039), in females with WC>88 cm(-1.9±1.5 vs. -2.4±1.2; p=0.008) and in females with ICO>0.5(-1.96±1.4 vs. -2.5±1.2; p=0.004). However, in normal-weight females and in those without central obesity, LS T-scores by DXA were not different than qCT. DXA at lumbar spine and proximal femur revealed osteoporosis in 47.7% and 11.4% respectively, while QCT detected osteoporosis in 61.4% of females (p<0.001). Measures of central obesity; ICO and WC were not associated with QCT bone mineral density (BMD) (r=0.14 and r=0.21, respectively), but were positively associated with both DXALS BMD (r=0.29 and r=0.31; p<0.05) and DXA proximal femur BMD (r=0.41 and r=0.44; p<0.01). Conclusion: Our results suggest that obesity is associated with lower T-scores by DXA compared to QCT. Caution is needed when assessing osteoporosis status in obese postmenopausal females. However, further studies with larger sample size are needed to confirm the findings.

Background: The relationship between inhaled corticosteroids and bone mineral density (BMD) remains uncertain despite extensive research. Methods: This was an international, multicenter, randomized, double-blind, parallel-group, 3-year noninferiority study. Patients with chronic obstructive pulmonary disease (COPD) (⩾40 years of age; smoking history ⩾10 pack years) and at least one native hip evaluable for BMD were enrolled and randomized 1:1, stratified by sex, to treatment with vilanterol (VI) 25 µg or fluticasone furoate/vilanterol (FF/VI) 100 µg/25 µg. BMD measurements were taken via dual-energy X-ray absorptiometry every 6 months. The primary endpoint was assessment of the noninferiority of change from baseline in total hip BMD per year at the −1% noninferiority level. Change from baseline in BMD at the lumbar spine and BMD measurements by sex were secondary endpoints. Incidences of COPD exacerbations and bone fractures throughout the study were also recorded. Results: Of 283 randomized patients, 170 (60%) completed the study. Noninferiority was demonstrated for FF/VI versus VI with regards to change from baseline in total hip BMD per year, with changes of −0.27% and 0.18%, respectively, and a treatment difference of −0.46% per year [95% confidence interval (CI) −0.97 to 0.06]. The treatment difference for FF/VI versus VI regarding lumbar spine BMD was −0.51% per year (95% CI −1.11 to 0.10). COPD exacerbations and bone fracture rates were similar between treatment groups. Conclusion: FF/VI showed noninferiority to VI for change from baseline in total hip BMD per year, when assessed at the −1% noninferiority margin in a combined sample of men and women with COPD.

Objective: The aim of the study was to find out the risk factor of bone mineral density (BMD). Methodology: Cross-sectional data were collected on 233 participants (males and females) with age ranging from 20 to 70 years. The subjects were divided into two groups consisting of young adults of 20–45 years and older adults of >45 years. The BMD was calculated by a heel ultrasonic test. Each subject was measured for various adiposity markers like body fat, body mass index, body shape index (BSI), body adiposity index and lifestyle parameters. Results: BSI was found to be higher among older adults in both males and females. The risk of osteoporosis and osteopenia was also seen to be significantly higher among older adults of >45 years ( p < 0.001). Various factors like age ( p < 0.001), milk intake status ( p < 0.05), education ( p < 0.01), occupation ( p < 0.05) and body adiposity index ( p < 0.05) were found to be risks for osteoporosis and osteopenia. Conclusion: In our study, BMD was found to be highly correlated with age, and the risk of osteopenia and osteoporosis increased as age increased. Illiteracy, milk consumption status, homemakers and higher body adiposity were also identified as risk factors for developing osteopenia and osteoporosis.
