Abstract Context Bone mineral density (BMD) decreases rapidly during the menopause transition (MT), and continues to decline in postmenopause. Objective To examine whether faster BMD loss during the combined MT and early postmenopause is associated with incident fracture, independent of starting BMD, before the MT. Design and Setting The Study of Women’s Health Across the Nation (SWAN), a longitudinal cohort study. Patients or Participants 451 women, initially pre- or early perimenopausal, and transitioned to postmenopause. Main outcome measures Time to first fracture after early postmenopause. Results In Cox proportional hazards regression, adjusted for age, body mass index, race/ethnicity, study site, use of vitamin D and calcium supplements, and use of bone--detrimental or beneficial medications, each SD decrement in lumbar spine (LS) BMD before the MT was associated with a 78% increment in fracture hazard (p=0.007). Each 1% per year faster decline in LS BMD was related to a 56% greater fracture hazard (p=0.04). Rate of LS BMD decline predicted future fracture, independent of starting BMD. Women with a starting LS BMD below the sample median, and a LS BMD decline rate faster than the sample median had a 2.7-fold greater fracture hazard (p=0.03). At the FN, neither starting BMD nor rate of BMD decline was associated with fracture. Conclusions At the LS, starting BMD before the MT and rate of decline during the combined MT and early postmenopause are independent risk factors for fracture. Women with below-median starting LS BMD and faster-than-median LS BMD decline have the greatest fracture risk.

Abstract Context Menopause before age 45 is a risk factor for fractures, but menopause occurs at age 45 or later in ~90% of women. Objective To determine, in women with menopause at age 45 or later, whether: 1) years since the FMP is more strongly associated with postmenopausal bone mineral density (BMD) than chronological age; and 2) lower age at FMP is related to more fractures. Design and Setting The Study of Women’s Health Across the Nation, a longitudinal cohort study of the menopause transition (MT). Participants A diverse cohort of ambulatory women (pre- or early perimenopausal at baseline, with 15 near-annual follow-up assessments). Main Outcome Measures 1) Postmenopausal lumbar spine (LS) or femoral neck (FN) BMD (N=1,038); 2) Time to fracture (N=1,554). Results Adjusted for age, BMI, cigarette use, alcohol intake, baseline LS or FN BMD, baseline MT stage, and study site using multivariable linear regression, each additional year after the FMP was associated with 0.006 (p<0.0001) and 0.004 (p<0.0001) g/cm 2 lower postmenopausal LS and FN BMD, respectively. Age was not related to FN BMD independent of years since FMP. In Cox proportional hazards regression, accounting for race/ethnicity, BMI, cigarette use, alcohol intake, prior fracture, diabetes status, exposure to bone-modifying medications/supplements, and study site, the hazard for incident fracture was 5% greater for each one-year decrement in age at FMP (p=0.02). Conclusions Years since the FMP is more strongly associated with postmenopausal BMD than chronological age, and earlier menopause is associated with more fractures.

Background:Dual energy X-ray absoprtiometry is the reference method to mesure bone mineral density (1). Loss of bone mineral density is significant if it exceeds the least significant change. The threshold value used in general population is 0,03 g/cm2 (2). Patients with obesity are known for having a higher bone mineral density due to metabolism and physiopathology characteristics (3,4).Objectives:The aim of our study was to determine the least significant change in bone densitometry in patients with obesity.Methods:We conducted an interventionnal study in 120 patients with obesity who performed a bone densitometry. We measured twice the bone mineral density at the lumbar spine, the femoral neck and the total hip in the same time (5,6). We determined the least significant change in bone densitometry from each pair of measurements, using the Bland and Altman method. We also determined the least significant change in bone densitometry according to each stage of obesity.Results:The least significant change in bone densitometry in patients with obesity is 0,046g/cm2 at the lumbar spine, 0.069 g/cm2 at the femoral neck and 0.06 g/cm2 at the total hip.Conclusion:The least significant change in bone densitometry in patients with obesity is higher than in general population. These results may improve DXA interpretation in this specific population, and may personnalize their medical care.References:[1]Lees B, Stevenson JC.

Background:Hand osteoarthritis (OA) and its more severe subset erosive hand OA are common causes of pain and morbidity. Some metabolic factors were suggested to be implicated in erosive disease. Few studies investigated differences in systemic bone loss between erosive and non-erosive hand OA.Objectives:To compare the change of bone mineral density (BMD) between patients with erosive and non-erosive hand OA in a two-year longitudinal study.Methods:Consecutive patients with symptomatic HOA fulfilling the American College of Rheumatology (ACR) criteria were included in this study. Erosive hand OA was defined by at least one erosive interphalangeal joint. All patients underwent clinical assessments of joint swelling and radiographs of both hands. DEXA examination of lumbar spine, total femur and femur neck was performed at the baseline and after two years.Results:Altogether, 141patients (15 male) with symptomatic nodal HOA were included in this study and followed between April 2012 and January 2019. Out of these patients, 80 had erosive disease after two years. The disease duration (p<0.01) was significantly higher in patients with erosive compared with non-erosive disease at baseline.Osteoporosis (T-score <-2.5 SD) was diagnosed in 12.5% (9/72) of patients with erosive hand OA and in 8.06% (5/57) of patients with non-erosive hand OA at baseline. BMD was significantly lowered in patients with erosive compared with non-erosive disease at baseline (lumbar spine: 1.05g/cm2 vs. 1.13 g/cm2, p<0.05, total femur: 0.90 g/cm2 vs. 0.97 g/cm2, p<0.01 and femur neck: 0.86 g/cm2 vs. 0.91, p<0.05). T-scores of lumbar spine (-0.96 vs. -0.41 SD, p<0.05), total femur (-0.69 vs. -0.33 SD, p<0.05) and femur neck (-1.14 vs. -0.88 SD, p<0.05) were also significantly lowered in patients with erosive compared with non-erosive disease.Two years, the BMD remained also significantly lowered in patients with erosive compared with non-erosive disease (lumbar spine: 1.05g/cm2 vs. 1.14 g/cm2, p<0.05, total femur: 0.92 g/cm2 vs. 0.97 g/cm2, p<0.05 and femur neck: 0.86 g/cm2 vs. 0.91, p<0.05), which was in agreement with the finding for T-scores of lumbar spine (-1.05 vs. -0.39 SD, p<0.05), total femur (-0.74 vs. -0.34 SD, p<0.01) and femur neck (-1.07 vs. -0.72 SD, p<0.01).Conclusion:These results suggest that patients with erosive hand OA are at higher risk for the development of general bone loss. Over two years patients with erosive disease had significant lower bone mineral density at all measured sites.References:[1]This work was supported by the project AZV no. 18-00542 and MHCR No. 023728.Acknowledgments:Project AZV no. 18-00542 and MHCR No. 023728Disclosure of Interests:Karel Pavelka Consultant of: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Speakers bureau: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Ladislav Šenolt: None declared, Olga Sleglova: None declared, Jiří Baloun: None declared, Olga Růžičková: None declared

Objectives:To examine bone mineral density (BMD) in men with coronary heart disease (CHD), depending on the state of the muscle mass, strength and function.Methods:79 men aged over 50 years with verified CHD were examined (mean age 63 (57; 66) years).The BMD and T-criterion (standart deviation, SD) of the femoral neck and lumbar spine (L1-L4) were evaluated using dual-energy x-ray absorptiometry (DXA) on the Lunar Prodigy Primo bone densitometer (USA). The following reference intervals were used: normal BMD values (T-criterion ≥-1), osteopenia (OPe) (T-criterion from -1 to -2.5), and osteoporosis (OP) (T-criterion <-2.5).To assess muscle mass, the total area (cm2) of the lumbar muscles of the axial section at the level of the 3rd lumbar vertebra (L3) was determined using multispiral computed tomography on a 64-slice computer tomograph “Somatom Sensation 64” (Siemens AG Medical Solution, Germany). The ratio of the obtained index of the area of skeletal muscle to the square of the patient’s growth index determined the “ skeletalmuscular index L3” (SMI). The media considered the threshold value to be 52.4 cm2/m2.Results:The femoral neck BMD in the examined patients was 0.96 (0.89; 1.03) g/cm2, which corresponds to -0.50 (-1.00; 0) SD according to the T-criterion, in the lumbar spine -1.23 (1.11; 1.32) g/cm2and 0.4 (-0.50; 1.20) SD according to the T-criterion.In accordance with the recommendations of the European working group on sarcopenia in Older people (EWGSOP, 2010, 2018), the patients were divided into 3 groups: 31 patients without sarcopenia (group 1), 21 patients with isolated muscle loss (presarcopenia) (group 2) and 27 patients with sarcopenia (group 3).BMD in the femoral neck in the group of patients without sarcopenia was 0.96 (0.72; 1.26) g/cm2, which corresponds to -0.50 (-0.8; 0.2) SD according to the T-criterion, in the lumbar spine – 1.19 (1.10; 1.275) g/cm2and 0.1 (-0.6; 0.8) SD according to the T-criterion. BMD in the femoral neck in the group of patients with presarcopenia (group 2) – 0.995 (0.94; 1.04) g/cm2and -0.3 (-0.70; 0) SD according to the T-criterion, in the lumbar spine – 1.32 (1.24; 1.40) g/cm2and 1.20 (0.50; 1.90) SD according to the T-criterion. In patients with established sarcopenia (group 3), the following indicators of BMD and T-criterion were recorded: 0.95 (0.845; 0.98) g/cm2and -0.60 (-1.40; -0.40) SD and 1.23 (0.085; 1.31) g/cm2and 0.4 (-0.8; 1.1) SD in the femoral neck and lumbar spine, respectively.A comparative analysis of the results of the DXA found that patients with sarcopenia had a significant decrease in the BMD and T-criterion in the femoral neck compared to patients with presarcopenia (p=0.039 and p=0.040, respectively). There were no differences between the groups of patients without sarcopenia and with sarcopenia and presarcopenia (p>0.05).It was found that patients with sarcopenia had significantly lower BMD and T-criterion in the lumbar spine compared to patients with presarcopenia (p=0.017 and p=0.0165, respectively). The values of the BMD and T-criterion in the groups of patients without sarcopenia and with presarcopenia and sarcopenia in the lumbar spine were comparable (p>0.05).Conclusion:The presence of sarcopenia is associated with loss of BMD in the femoral neck and in the lumbar spine. The results obtained confirm the high probability of common pathogenetic links between OP and sarcopenia.Disclosure of Interests:None declared

ObjectiveTo investigate if in radiographic axial Spondyloarthritis (r-axSpA) low vertebral bone mineral density (BMD) is associated with development of new syndesmophytes at the same vertebral level.MethodsIn a post-hoc analysis from the ASSERT trial (infliximab vs placebo), dual-energy X-ray absorptiometry was used to measure baseline BMD (g/cm2) of the lumbar spine L1 to L4. Syndesmophyte formation was assessed in the same vertebrae on conventional radiographs defined as an increase in modified Stoke Ankylosing Spondylitis Spine Score from 0 or 1 to 2 or 3 after 2 years. Radiographs were scored by two readers. Generalised estimating equations (GEE) adjusted for within-patient correlation across multiple vertebrae, taking potential confounders into account.ResultsWe analysed 599 vertebrae in 165 r-axSpA patients (78% male, mean (SD) age 38 (10) years, 67% with at least one syndesmophyte anywhere in the spine). In total, 24 to 74 new syndesmophytes developed in 9 (5%) to 30 (18%) patients and 13 (2%) to 39 (7%) vertebrae, if either a syndesmophyte was seen by both or only one of the readers (ie, specific and sensitive definitions) respectively. In multivariable analyses, no association was found between baseline local vertebral BMD and new syndesmophyte formation after 2 years: adjOR (95% CI): 0.56 (0.01, 44.45) (specific definition) and 0.26 (0.03, 2.63) (sensitive definition).ConclusionIn patients with active and established r-axSpA, with an observed low incidence of lumbar spine syndesmophyte formation over 2 years, no relationship was found between baseline BMD and new radiographic syndesmophyte formation at the same vertebra.
