9 Background: Osteoporosis and breast cancer (BC) are each mediated by circulating estrogens. Insulin and insulin growth factors 1-2 have been linked to increased bone mineral density (BMD) and BC cell growth. The relationship between BMD and BC incidence has been analyzed in a number of retrospective studies with conflicting results. We have previously reported on a study of BC risk in 15,268 women who underwent BMD testing. Women in the highest Z-score tertile at the femoral neck had a higher risk of developing BC compared to those in the lowest tertile (OR 2.15, p = 0.004). The current study was undertaken in order to determine whether there is a direct correlation between BMD and BC when evaluated prospectively. Methods: This case-control study is planned to include 400 consecutive patients (pts) with newly diagnosed BC and 800 matched controls without BC. Pts and controls undergo BMD examination using dual photon technology. Serum is obtained for vitamin D, calcium, and a panel of bone turnover markers and cytokines. Pts and controls are interviewed and a questionnaire about BC and osteoporosis risk factors is completed. Results: We present clinical and BMD data from the first 200 BC patients recruited to the study. Median age 60, interquartile range 49.5-66. Body Mass Index: 28.4 ± 5.4 (mean ± SD). Postmenopausal: 148 patients, 74%. T-scores (mean ± SD): femoral neck: -0.68 ±-1.10, total hip: -0.28 ± 1.17, L1-L4: -0.52 ± 1.39. T-score of less than minus 2.5 (cut-off for osteoporosis) at any of the 3 sites, 24 (11.9 %) pts. Estrogen receptor pos: 162 (81%).BC stage: T0-T2, 175 (87.5 %). N0: 108 (54.5%), N1-2-3: 86 (43.4%). % pts node pos (N1-2-3) in each T score range: ≤ -2.5, 20%; -2.5 < T score ≤ -1,36%; -1 < T-score ≤+ 1,50%; +1 < T-score, 60%. % pts low grade in each T score range: ≤ -2.5, 25%;-2.5 < T-score ≤ -1,35%;-1 < T-score ≤ +1,37 % ;+1 < T-score, 20%. Conclusions: Only 11.9% of the first 200 BC patients studied had osteoporosis by BMD at diagnosis.Pts with higher BMD showed a trend for more nodal involvement. Pts with T-score > +1 had fewer cases of low grade histology compared to pts with lower T-scores. These preliminary results hint that higher BMD may be associated with more aggressive BC.

The Relationship

(1) Osteoporosis and sarcopenia are frequent pathologies among the geriatric population. The interlink between these two diseases is supported by their common pathophysiology. The aim is to explore the relationship between bone mineral density (BMD) and body composition in women aged 75 or older. (2) From January 2016 to December 2019, women aged 75 or older of Caucasian ethnicity, who were addressed to perform a biphoton absorptiometry (DXA), were included in this observational study. Femoral neck T-score, lean mass, fat mass, and physical performances were measured. (3) The mean age of 101 patients included was 84.8 (±4.9) years old. Osteoporosis was present in 72% of patients. According to EWGSOP criteria, 37% of patients were sarcopenic. Osteosarcopenia was present in 34% of patients. The femoral neck T-score was significantly associated with fat mass (β = 0.02, 95% CI (0.01; 0.03), p < 0.05) in multivariable analysis. Osteosarcopenic patients had significantly lower fat mass (16.2 kg (±6.8) vs. 23.1 kg (±10.8), p < 0.001) and body mass index (BMI) (20.7 kg/m2 (±2.8) vs. 26.7 kg/m2 (±5.6), p < 0.001). (4) In postmenopausal women, fat mass is estimated to provide hormonal protection. While osteosarcopenia is described as a lipotoxic disease, fat mass and BMI would appear to protect against the risk of osteosarcopenia. This raises questions about the relevance of BMI and DXA.

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.

CONTEXT AND OBJECTIVE: Osteoporosis and fragility fractures are an important public health problem. Although bone loss occurs with age universally, the incidence of bone loss fractures varies greatly between racial groups. The aim of this study was to examine the relationship between calcium, protein and energy intake and the bone mineral density of the femoral neck in Brazilian black and white men. DESIGN AND SETTING: This was a cross-sectional study, carried out in a teaching hospital in São Paulo. METHODS: The participants were 277 volunteer men, aged 50 years or older. The bone mineral density of the femoral neck (FNBMD) was measured by dual energy x-ray absorptiometry. The relationship between FNBMD and calcium, protein and energy intake, as assessed by a three-day food record, was analyzed using multiple linear regression models and was adjusted for age, height, physical activity and education level. The analysis was stratified by race (white and black). RESULTS: FNBMD presented similar means in the two racial groups (p = 0.538). Protein and energy intake did not show a significant correlation with FNBMD, either in the white or in the black population. Calcium intake showed a strong and independent correlation with FNBMD in the black men (partial r = 0.42). CONCLUSION: Calcium intake was a determinant of FNBMD for black men, aged 50 years or older, but not for the white ones.

Abstract Background: Osteoporosis among adult males is a major and under-recognized problem in the United States. Patients with hemophilia have several predisposing risks for developing decreased bone mineral density (BMD) and osteoporosis, and may represent an important group to target for screening and treatment for fracture prevention. Patients and Methods: Patients over the age of 18 with moderate or severe hemophilia A or B (as defined by factor activity < 5%) and no history of prophylactic factor use prior to age 10 were eligible. Bone mineral densities were obtained using DEXA scans (DXA) along with measurements of joint mobility and physical activity and laboratory parameters. Results: Twenty-eight patients have been consented with accrual ongoing. 21 have undergone DXA scans. Median age of 39 (range 18–61), 86% HCV positive, 26% HIV positive. Median T-score for all sites (lumbar, femoral neck, hip, and other) was −1.7 (−5.8–0.6), with the most effected area being the femoral neck, T-score −1.7 (−5.8–0.8). Based on WHO criteria, 76% of patients had decreased BMD, 33% (n=7) with osteoporosis, and 43% (n=9) with osteopenia. Trends associated with decreased BMD included decreased serum 25-hydroxy-vitamin D levels, increased alkaline phosphatase, and decreased weight. All patients with osteoporosis were HCV positive, and all HIV positive patients had decreased BMD. Median activity scores were lower among osteoporotic patients vs normal BMD. Joint range-of-motion in the lower extremities was limited to 59.5% of predicted values in patients with osteoporosis, 84% in osteopenia, and 93% in patients with normal BMD. Summary: Patients with hemophilia are at markedly increased risk for developing osteoporosis and osteopenia. Potential predictors of risk for decreased BMD are concurrent HCV and HIV infection, low vitamin D levels, elevated alkaline phosphatase, lower weight, decreased range of motion and lower activity scores. More aggressive screening for decreased BMD among moderate and severe hemophilia patients with initiation of therapy is appropriate.

The Relationship

Background:The relationship between lean mass (LM), fat mass (FM) and bone mineral density (BMD) remains controversial. Some population studies have emphasized the positive association between them, while others have found an inverse relationship. RA patients are characterized by a decrease in muscle mass and an increase in fat mass. Such changes in body composition may be associated with low BMD.Objectives:To study the relationship between BMD, LM and FM in postmenopausal women with RA.Methods:68 postmenopausal women with RA (median age 59 [54; 63] years) were included in the study. BMD and body composition were evaluated using two-energy X-ray absorptiometry. Correlation analysis between body composition parameters and BMD was performed with the Spearman method, correlation coefficients R for p<0.05 are presented.Results:The average L1-L4 BMD was 0,92±0,16 g/cm2, total hip BMD - 0,84±0,15 g/cm2 and femoral neck - 0,73±0,13 g/cm2. 33 (48.5%) women had osteopenia, and 17 (25.0%) - osteoporosis (OP). Low appendicular LM was found in 5 (7.4%) and low appendicular muscle index (appendicular LM/height2, AMI) – in 10 (14.7%) patients. Overfat was revealed in 47 (69.1%) women, but only 20 (29.4%) women had BMI corresponding to obesity. The positive correlations between BMD in L1-L4, total hip and femoral neck regions and body weight (R=0.46, R=0.56 and R=0.50, respectively), trunk fat (R=0.4, R=0.51 and R=0.37, respectively), total FM (R=0.27, R=0.43 and R=0.34, respectively), trunk LM (R=0.55, R=0.54 and R=0.51, respectively), total LM (R=0.51, R=0.50 and R=0.52, respectively), appendicular LM (R=0.31, R=0.29 and R=0.37, respectively) and AMI (R=0.26, R=0.33 and R=0.51, respectively) were found out. In the multivariate linear regression analysis total LM was associated with BMD of lumbar spine (β=0.638, p=0.001) and total hip (β=0.473, p=0.008), and AMI - with femoral neck BMD (β=0.360; p=0.014). We found that FM hadn’t a significant effect on BMD in any region.Conclusion:73.5% of patients with RA had a reduced BMD, and 14.7% women – low AMI. LM was positively associated with BMDs in different regions of interest, but FM had no effect on BMD. Further researches are needed to identify associations between body composition, inflammatory activity and bone health in patients with RA.Disclosure of Interests:None declared

Background:Teriparatide has been shown to increase spine and hip bone mineral density (BMD) and to reduce vertebral and non-vertebral fractures. (1) It is currently not clear whether the effect of teriparatide is dependent on the baseline risk of fracture or osteoporosis (OP) type, a finding that could have an impact on our therapeutic decision.Objectives:Investigate if there is a relationship between teriparatide effect in BMD and baseline 10-year fracture probability, assessed using FRAX®, in primary and secondary OP patients.Methods:This is a longitudinal, retrospective study including consecutive patients with the diagnosis of OP treated with teriparatide for 24 months, with a ten-year follow-up period, at our rheumatology department. Demographic, clinical, laboratorial, BMD and occurrence of fracture data were collected. The 10-year risk of osteoporotic fracture was estimated using the fracture risk assessment tool (FRAX) v 4.1 with the Portuguese population reference. Statistical analysis was performed using the software SPSS 23.0. Correlations between continuous variables were evaluated with spearman coefficient. p<0.05 was considered statistically significant.Results:Eighty patients (88.8% female, median age 65.00 (59; 75)) were included. Forty-nine patients (61.3%) has secondary OP, mainly of cortisonic etiology (61.2%, n=30). Before treatment, median lumbar spine BMD was 0.870 [0.767, 0.964] g/cm2, median T-score of -2.60 (-3.30, -1.90); median total femur BMD was 0.742 [0.667, 0.863] g/cm2, median T-score of -2.10 (-2.80, -1.30); median femoral neck BMD was 0.671 [0.611, 0.787] g/cm2, median T-score of -2.50 [-3.20, -1.85]. Regarding fracture risk, median FRAX-based 10-year major fracture risk (with BMD) at baseline was 16% [10.0; 23], and median hip fracture risk was 7.2% [3.4; 13.8].The median variation of BMD, after finishing teriparatide treatment, in the spine was 0.107 [0.029; 0.228]; median BMD variation in total femur was 0.013 [-0.013; 0.068] and median BMD femoral neck was 0.046 [-0.002; 0.109]. We observed a numerically superior effect, albeit without any statistical significance, of teriparatide on bone mineral density gain in secondary OP (versus primary OP) at lumbar spine, total femur and femoral neck.Most patients continued anti-osteoporotic treatment with a bisphosphonate (81.2%, n=65) and, during follow-up, 17 patients had an incident fracture (8 hip fractures and 6 vertebral fractures), median of 5 [1.75, 8.25] years after ending teriparatide.We found a discrete correlation between FRAX-based hip fracture probability and the variation of bone mineral density in total femur (Spearman’s coefficient 0.248, p = 0.04). There was no correlation between FRAX-based major fracture probability and and the variation of bone mineral density in the spine or femur. When we separately analyze the relationship between the variation in total hip BMD and the FRAX-based fracture risk, depending on whether it is a secondary or primary OP, we find that the correlation is stronger and only remains in secondary OP (Spearman’s coefficient 0.348, p = 0.03).Conclusion:Our data suggest that teriparatide could be an important weapon in the treatment of secondary cause OP, particularly cortisonic, and in patients at high fracture risk, although further larger studies are needed to confirm these findings.References:[1]Kendler DL, Marin F, Zerbini CAF, Russo LA, Greenspan SL, Zikan V, Bagur A, Malouf-Sierra J, Lakatos P, Fahrleitner-Pammer A, Lespessailles E, Minisola S, Body JJ, Geusens P, Möricke R, López-Romero P.

Background: The association between ankle fractures in elderly patients and low bone mineral density (BMD) has recently been recognized, but the effect of BMD on the postoperative outcome of these fractures is unknown. The aim of this study was to investigate the effect of BMD on the postoperative outcome of ankle fractures in elderly patients to evaluate the need for BMD screening. Methods: We retrospectively reviewed 48 patients aged 65 years or older who had ankle fractures and underwent dual-energy x-ray absorptiometry to assess BMD after surgical treatment of the fracture. Postoperative outcomes were assessed using the Olerud-Molander Ankle Score (OMAS), visual analog scale (VAS) score for pain, Kellgren and Lawrence (K&L) grading scale score, and quality of fracture reduction. The correlation between the BMD and the outcome measures at 12 months after surgery was analyzed using the Pearson correlation coefficient. Results: The mean absolute value of BMD was 0.6 ± 0.1 g/cm2 (T-score, –1.5 ± 1.2) at the femoral neck and 0.8 ± 0.2 g/cm2 (T-score, –1.2 ± 1.5) at the lumbar spine. Osteoporosis was present in 33% of female patients and in 11% of male patients. At 12 months after surgery, the OMAS was 70 ± 17 and the VAS score for pain was 18 ± 17. Of the patients, 20, 21, 5, 1, and 1 had K&L grades of 0, 1, 2, 3, and 4, respectively. None of the clinical and radiographic outcome measures were correlated with the BMD values of the patients. Conclusion: The postoperative outcome of the ankle fractures in elderly patients at 12 months after surgery showed no correlation with femoral neck or lumbar spine BMD at the time of fracture. Level of Evidence: Level III, retrospective comparative study.

Abstract IntroductionBoth erosions and osteoporosis are present in rheumatoid arthritis and are related to RANK-L pathway activation. The aim of the study was to evaluate the relationship between erosion and bone mineral density (BMD) in RA and whether it can be driven by autoimmunity.Patients and methodsPatients followed in the Department of Rheumatology between January 2008 and May 2019 satisfied the 1987 ACR or 2010 ACR-EULAR criteria. Erosions were evaluated by the modified Sharp/van der Heidje erosion score (SHSe) on radiographs and bone mineral density (BMD) in g/cm2 and by the T-score at the hip on DXA. The presence and titers of ACPA as well as rheumatoid factor (RF) and anti-nuclear antibodies (ANAs) were recorded at intervals of less than 2 years for both DXA and radiography.ResultsA total of 149 patients met the inclusion criteria. A total of 61.1% were ACPA positive, 79.9% were erosive and 10.7% had a hip T-score ≤-2.5. ACPA status but not titers was associated with a higher erosion score (63.0 (53.2) for ACPA + vs. 45.5 (44.1) for ACPA – (p= 0.04)). ACPA titers were associated with lower BMD at the hip (value -0.216; p=0.01) but not with T-score. A higher erosion score was associated with a lower BMD (R2: 0,049 and value: -0.222; p=0.009) and T-score (R2: 0,158 and value -0.397; p<0.0001) at the hip. In linear regression, erosion and systemic bone loss were still associated with but not driven by ACPA status or titer. RF and ANA did not demonstrate any role in this association.ConclusionWe showed that the relationship between erosion and bone mineral density associated with RA does not seem to be driven by ACPA or other autoimmunity parameters. However, the presence of ACPA or erosion should lead to osteoporosis assessment.
