Trabecular bone score (TBS) is a novel method for assessing trabecular microarchitecture. Normative values of TBS are available for various populations of the world but are not yet available for Taiwanese adults. Therefore, the purpose of this study was to estimate age-specific, normative TBS curves for Taiwanese men and women. Medical records of general health examinations from a regional hospital in Southern Taiwan were reviewed. Individuals aged 30–90 years with data on lumbar spine bone mineral density (BMD) were included. TBS was retrospectively calculated from dual-energy X-ray absorptiometry scans using TBS iNsight software. Of the 12,028 patients included, 4533 (37.7%) were male and the mean age was 55.8 years. The mean TBS was 1.392 (standard deviation (SD) 0.089) for men and 1.344 (SD 0.107) for women. In women, TBS declined at a rate of 0.0004/year among those aged 30.0–45.9 years, 0.0106/year among those 46.0–60.7 years, and 0.0028/year among those 60.8–90.0 years. In men, TBS declined at a constant rate of 0.0023/year over the entire age range. In conclusion, age-adjusted, normative curves of TBS for Taiwanese men and women are presented, which could be used to facilitate the use of TBS in assessing bone status in clinical practice.

Abstract Background Screening for osteoporosis with dual-energy X-ray absorptiometry (DXA) is recommended for male HIV-infected patients only above the age of 50. Recently, trabecular bone score (TBS) has been introduced as a novel tool to assess bone microarchitecture using DXA of the lumbar spine. Few studies have reported TBS values in HIV-infected individuals younger than 50 years of age. This study compared TBS values in young males infected with HIV and matched controls, and investigated the associations between TBS and demographic parameters, clinical parameters, and bone mineral density (BMD) scores. Methods A cross-sectional study of BMD and TBS in HIV-infected men (n = 80) aged between 18 and 50 years and age- and sex-matched controls (n = 80) was conducted. Results The proportion of patients with low BMD (Z-score ≤−2) was significantly greater among HIV-infected patients than among matched controls (21.3% [17/80] vs. 8.8% [7/80], p = 0.027). Mean TBS values were significantly lower in HIV-infected patients than in controls (1.41 ± 0.07 vs. 1.45 ± 0.07, p = 0.008). In both groups, TBS values were positively correlated with BMD at the lumbar spine, femoral neck, and total hip (p < 0.001); however, TBS was not correlated with body mass index. In the HIV group, TBS was negatively correlated with the duration of tenofovir disoproxil fumarate(TDF) exposure (p = 0.04). Conclusion Young men infected with HIV had abnormal bone trabecular microarchitecture, as assessed by both TBS and BMD. TBS values were correlated with both BMD and the duration of TDF exposure.

Background:In axial spondyloarthritis (axSpA) the risk of vertebral fracture is increased, not always corresponding with the values of bone mineral density (BMD). One possible explanation is that syndesmophytes interfere with these values. We consider whether the evaluation of trabecular microarchitecture by an accessible methodlike the Trabecular Bone Score (TBS), that does not involve additional irradiation neither seem to be influenced by the presence of syndesmophytes, may be an advantage to estimate the risk of fracture.Objectives:To estimate the prevalence of vertebral fractures in patients with axSpA. To assess the diagnostic accuracy of TBS and BMD for vertebral fracture, and if it is influenced by the presence of syndesmophytes. To analyze the correlation between the absolute values of BMD and TBS in the lumbar spine.Methods:Cross-sectional study. Patients were consecutive recruited. We collected demographic (sex, age), clinical (syndesmophytes, vertebral fracture, BASDAI, BASFI, time of evolution of axSpA, treatment) and analytical variables [vitamin D (1,25-OHD), CRP and ESR]. The BMD was determined using the Lunar Prodigy ProTM densitometer from GE Healthcare, to which the TBS iNsight® software version 2.2 was added to perform the TBS analysis. The presence of fracture was evaluated by radiology. The statistical analysis was performed with the SPSS 22.0 and OpenEpi softwares.Results:84 patients were included, 60 men and 24 women, with a mean age of 59 years (± SD 13). 51.2% had lumbar syndesmophytes. The prevalence of fractures was 13.7%, 95 CI (7.8-22.9). 51.2% were treated with NSAIDs, and 48.8% with biological drugs. The evolution of axSpA was > 10 years in 65.5%. The mean scores of BASDAI and BASFI were 3.7 and 4.3 respectively (± SD 2.2 and 2.3). The mean CRP value was 8.5 mg / L (± SD 8.4), ESR 12.2 mm / h (± SD 11.4) and 1.25-OHD 27.9 ng / dL (± SD 13.6).According to the lumbar and femoral T Score, 9.5% and 15.5% of the patients were in the range of osteoporosis respectively.19% patients had a low TBS value (≤1.23).Regarding the influence of syndesmophytes on TBS and BMD values, we found significant differences in lumbar spine BMD (p = 0.01) but not in total hip and femoral neck BMD (p = 0.2 and 0.3 respectively) nor in the TBS (p = 0.1).Regarding the correlation of TBS and BMD values of the spine, no correlation was observed in patients with syndesmophytes, while a moderate correlation (r = 0.4, p = 0.02) was observed in patients without syndesmophytes.In the univariate analysis, the factors related to the presence of vertebral fracture were age, female sex, absolute BMD values in the lumbar spine and total hip, and TBS values. No relationship was found with the rest of the variables. In the multivariate analysis, only the TBS showed a significant association with the presence of fractures (p =0.02).Regarding the predictive capacity of fractures, TBS showed a higher sensitivity than that of BMD (55.6% versus 18.2% and 30% of BMD in the spine and hip respectively), being the specificity comparable (85.3% versus 91.3% and 85.1% of BMD in column and hip respectively).Conclusion:the prevalence of fractures was 13.7% among the patients studied, 95 CI (7.8-22.9). The presence of syndesmophytes influenced the values of lumbar BMD but not the hip BMD or those of the TBS. We found a correlation between the values of BMD of the spine and TBS only in patients who did not have syndesmophytes. Only TBS values were significantly related to the presence of fractures in the multivariate analysis. TBS showed greater sensitivity with similar specificity than BMD for the detection of vertebral fractures.Disclosure of Interests:Ana V Orenes Vera: None declared, L Montolio-Chiva: None declared, I Vázquez-Gómez: None declared, Eduardo Flores: None declared, Elia Valls-Pascual Grant/research support from: Roche, Novartis, and AbbVie, Speakers bureau: AbbVie, Lilly, Pfizer, MSD, Novartis, Janssen, Bristol Myers Squibb, UCB Pharma, À Martínez-Ferrer: None declared, Desamparados Ybañez: None declared, Luis García-Ferrer: None declared, María Vega-Martínez: None declared, Magdalena Graells-Ferrer: None declared, A Sendra-García: None declared, V Núñez-Monje: None declared, Inmaculada Torner Hernández: None declared, Juanjo J Alegre-Sancho Consultant of: UCB, Roche, Sanofi, Boehringer, Celltrion, Paid instructor for: GSK, Speakers bureau: MSD, GSK, Lilly, Sanofi, Roche, UCB, Actelion, Pfizer, Abbvie, Novartis

Background: When compared to people without type 2 diabetes mellitus (T2DM), people with T2DM have an increase in fracture risk despite having higher bone mineral density (BMD). Many studies in Caucasians demonstrated that trabecular bone score (TBS) is lower in people with T2DM than those without. The utility of TBS as a fracture risk assessment tool in Asians with T2DM is currently unclear. Objective: To compared lumbar spine (LS) BMD and TBS in Thais with or without T2DM and investigate the correlation between TBS and hemoglobin A1c (HbA1c) and diabetes duration in participants with T2DM. Materials and Methods: The present study was a cross-sectional study that included 97 participants with T2DM (37 men and 60 women) and 342 participants without T2DM (174 men and 168 women). LS-BMD and TBS were obtained. Results: Men and women with T2DM were older and had higher body mass index (BMI). Men with T2DM had significant higher LS-BMD (1.051±0.166 versus 0.972±0.125, p=0.009) and non-significant lower TBS (1.333±0.084 versus 1.365±0.096, p=0.055) than those without. Similarly, women with T2DM had significant higher LS-BMD (0.995±0.155 versus 0.949±0.124, p=0.021) and lower TBS (1.292±0.105 versus 1.382±0.096, p<0.001). After adjusting for age and BMI, T2DM predicted higher BMD in men (p<0.001), but not in women (p=0.143). T2DM was not associated with TBS after adjusting for age and BMI in both genders (p=0.403 and p=0.151 in men and women, respectively). TBS did not correlate with HbA1c in both genders. However, TBS was non-significantly associated with diabetes duration in women (p=0.073), but not in men (p=0.639). Conclusion: T2DM significantly predicted higher LS-BMD only in men and was not independently associated with TBS in both genders. These data highlighted that, in T2DM, there was some variation in the clinical usefulness of BMD and TBS in predicting osteoporotic fractures with regard to clinical characteristic of participants.

Abstract Background Kidney transplant recipients (KTR) are at risk to lose bone mass. The trabecular bone score (TBS) represents a recently developed parameter of lumbar spine trabecular bone texture that correlates with the occurrence of fractures. Methods We analysed the 1-year changes in TBS in 44 de novo KTR that were randomized 1:1 to denosumab or no treatment. TBS was derived from dual energy X-ray absorptiometry and was correlated with 1-year areal bone mineral density (aBMD) changes at the lumbar spine and total hip. Correlations were also performed with parameters of peripheral bone microarchitecture and bone strength at the distal tibia and distal radius, as assessed by high-resolution peripheral quantitative computed tomography (HRpQCT) and micro-finite element analysis. Results The baseline TBS in KTR amounted to 1.312 ± 0.101, which is lower than the TBS of an age-matched normal control population (range 1.364–1.471). The TBS correlated positively with aBMD at the lumbar spine (Spearman’s ρ = 0.56; P < 0.001) and total hip (ρ = 0.33; P < 0.05). The baseline TBS also correlated with HRpQCT-derived total (ρ = 0.49; P < 0.05) and trabecular volumetric BMD (ρ = 0.57; P < 0.01) and trabecular separation (ρ = −0.46; P < 0.05) at the tibia. Denosumab treatment led to an increase in TBS, paralleling the BMD changes at the lumbar spine. Conclusions The TBS is a useful additional score of bone health, which may help to better define fracture risk. Treatment with denosumab led to improved trabecular bone texture in de novo KTR in addition to its beneficial effect on BMD.

Bone quality is a critical factor that, along with bone quantity, determines bone strength. Image-based parameters are used for assessing bone quality non-invasively. The trabecular bone score (TBS) is used to assess quality of trabecular bone and femur geometry for cortical bone. Little is known about the associations between these two bone quality parameters and whether they show differences in the relationships with age and body mass index (BMI). We investigated the associations between the trabecular bone score (TBS) and femur cortical geometry. Areal bone mineral density (BMD) was assessed using dual energy X-ray absorptiometry (DXA) and the TBS was assessed using iNsight software and, femur geometry using APEX (Hologic). A total of 452 men and 517 women aged 50 years and older with no medical history of a condition affecting bone metabolism were included. Z-scores for TBS and cortical thickness were calculated using the age-specific mean and SD for each parameter. A ‘discrepancy group’ was defined as patients whose absolute Z-score difference between TBS and cortical thickness was > 1 point. TBS and cortical thickness correlated negatively with age both in men and women, but the associations were stronger in women. Regarding the associations with BMI, TBS provided significant negative correlation with BMI in the range of BMI > 25 kg/m2. By contrast, cortical thickness correlated positively with BMI for all BMI ranges. These bone quality-related parameters, TBS and cortical thickness, significantly correlated, but discordance between these two parameters was observed in about one-third of the men and women (32.7% and 33.4%, respectively). Conclusively, image-based bone quality parameters for trabecular and cortical bone exhibit both similarities and differences in terms of their associations with age and BMI. These different profiles in TBS and FN cortical thickness might results in different risk profiles for the vertebral fractures or hip fractures in a certain percentage of people.
