193 Background: Decreased BMD is a common side effect of ADT, leading to increased fracture risk. Although loss of BMD appears to be greatest within the first 12 months of starting ADT, few data on BMD changes exist beyond 12 months, and other risk factors for bone loss in men on ADT are not well-characterized. Methods: Men age 50+ with non-metastatic prostate cancer and starting continuous ADT were enrolled in a prospective longitudinal study. BMD was determined by dual-energy x-ray absorptiometry at baseline and yearly for 3 years. A matched control group of men with prostate cancer but not on ADT was also enrolled. Medication use was recorded at each visit. Multivariable regression analyses were done to examine predictors of BMD loss. Results: 80 ADT users and 80 controls were enrolled (mean age 69.4 y); 49.7% had osteopenia and 4.6% had osteoporosis at baseline. ADT was associated with significant losses in lumbar spine BMD in year 1 compared to controls (p=0.004) and trends towards greater declines at femoral neck and total hip sites. Changes in year 2 and 3 were much smaller and not statistically different from controls (Table). Vitamin D use but not calcium use was associated with improved BMD at the lumbar spine in year 1 (+5.77%, p=0.006) with positive trends at other sites (+2.19% femoral neck, +1.76% total hip) primarily in year 1. Age was not associated with changes in BMD. Conclusions: Losses in BMD with ADT use are greatest at the lumbar spine and in the first year compared to years 2 and 3 and are independent of age. Vitamin D appears to be protective particularly in the first year of ADT use. [Table: see text]

Abstract Background: There are limited clinical studies aimed at solving the problem of the efficiency of conventional treatment with oral phosphate and calcitriol in adults with hypophosphatemic osteomalacia (HO). In addition, there still had no good non-hazardous markers to evaluate the severity of bone loss of osteomalacia before and after treatment. Therefore, the purpose of this study was to assess the efficacy of conventional treatment with a self-blended phosphate supplementation and calcitriol on patients with HO and whether bone mineral density (BMD) can helpful for monitoring the efficacy. Methods: 21 HO patients and 105 healthy controls were enrolled. HO patients with calcium and calcitriol were divided into three phosphate treatment groups: Patients in group A (n=3) received continuous phosphate supplementation, patients in group B (n=5) received intermittent phosphate supplementation and patients in group C (n=3) received no phosphate supplementation. 11 of 21 HO patients were recalled for detection of BMD of the lumbar spine (L1–L4), femoral neck, and total left hip three years after the treatment. Results: The average initial serum phosphorus level of the patient group was approximately 50% lower than that of the control group. Lower BMD was significantly observed in the HO group than the control group at the lumbar spine and total hip. Continuous treatment with the phosphate supplement could increase BMD in the lumbar spine and total hip by 33.4–52.3% and the femoral neck increased by 43.2–79.3% compared with baseline, and the effect appears to be continued once treatment is discontinued. Conclusions: These findings suggest that conventional therapy can improve bone mineral defects in patients with HO, especially in the femoral neck. Detection of BMD in HO patients is a good tool to assess the extent of bone defects and the therapeutic effect.

We aimed to evaluate the change in bone mineral density (BMD) in patients with prostate cancer (PCa) receiving androgen deprivation therapy (ADT) compared to those with PCa or other urologic conditions not receiving ADT. Literature searches were conducted throughout October 2018. The eligibility of each study was assessed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the Participant, Intervention, Comparator, Outcome, and Study design method. The outcomes analyzed were the mean difference (MD) of percent changes in BMD of lumbar spine, femur neck, and total hip. Five prospective cohort studies with a total of 533 patients were included in the present study. Statistically significant decreases of BMD change relative to the control group were observed in the ADT treatment group in the lumbar spine (MD −3.60, 95% CI −6.72 to −0.47, P = 0.02), femoral neck (MD −3.11, 95% CI −4.73 to −1.48, P = 0.0002), and total hip (MD −1.59, 95% CI −2.99 to −0.19, P = 0.03). There is a significant relationship between ADT and BMD reduction in patients with PCa. Regular BMD testing and the optimal treatment for BMD loss should, therefore, be considered in patients with PCa undergoing ADT.

Purpose: This meta-analysis aimed to compare the efficacy and safety of teriparatide vs. bisphosphonates in the management of osteoporosis. Methods: A total of 1,967 patients from eight randomized controlled trials were analyzed; outcomes included bone mineral density (BMD) of the femoral neck, total hip and lumbar spine, vertebral and nonvertebral fractures and any adverse event. A subgroup analysis of treatment effectiveness was performed according to the etiology of osteoporosis; i.e., glucocorticoid-induced osteoporosis (GIO) vs. post-menopausal osteoporosis (PO). Results: Teriparatide increased the BMD of the lumbar spine, femoral neck and total hip to a greater extent than bisphosphonates. Patients treated with teriparatide also had a lower risk of vertebral fractures compared with bisphosphonates; however, no difference in risk of nonvertebral fractures (or adverse events) was found. GIO subgroups showed larger increases in BMD of the lumbar spine, total hip and femoral neck in patients treated with teriparatide compared with bisphosphonates. The PO subgroup showed larger increases in BMD of the lumbar spine in patients treated with teriparatide compared with bisphosphonates. Patients in the GIO subgroup (but not the PO subgroup) were less likely to suffer a vertebral fracture on teriparatide as compared with bisphosphonates. In contrast, no significant difference in the percentage of nonvertebral fractures was noted between the two types of treatment for either subgroup. Conclusion: Teriparatide significantly increased the BMD of lumbar spine, total hip and femoral neck, particularly in GIO-induced osteoporosis. Teriparatide did not lower the risk of nonvertebral fractures when compared with bisphosphonates.

Prevalence Of Osteoporosis

To assess the prevalence of osteoporosis in young men with hypogonadotropic hypogonadism (HH) and to investigate the changes of BMD and metabolic parameters, a total of 22 young male patients with HH and 20 healthy controls were enrolled in the study. BMD, biochemical, and hormonal parameters were measured in two groups. Osteoporosis was more prevalent in HH patients (45.45%) than the control subjects (10.00%) (P<0.001). The patients with HH had lower BMD in lumbar spine 2–4, femoral neck, and total hip (P<0.001, for all) and higher fasting insulin (P=0.001), HOMA-IR (P=0.002), and SHBG (P<0.001) compared to the controls. After 6 months of pulsatile gonadorelin treatment, BMI (P=0.021) and BMD in lumbar spine 2–4, femoral neck, and total hip (P=0.002,P=0.003, andP=0.003, resp.) increased dramatically and total cholesterol (P=0.034), fasting insulin (P=0.025), HOMA-IR (P=0.021), and SHBG (P=0.001) decreased significantly in HH patients. The study shows a higher prevalence of osteoporosis in young men with HH. Long-term pulsatile gonadorelin treatment indicates a positive effect on BMD and metabolic parameters of HH patients.

Abstract Context Teriparatide and denosumab are effective treatments for osteoporosis and typically reserved as second-line options after patients have used bisphosphonates. However, limited head-to-head comparative effectiveness data exist between teriparatide and denosumab. Objective We compared changes in bone mineral density (BMD) between groups treated with teriparatide or denosumab after using bisphosphonates, focusing on the change in BMD while on either drug over 2 years. Design Observational cohort study using electronic medical records from two academic medical centers in the United States. Participants The study population included osteoporotic patients >45 years who received bisphosphonates >1 year before switching to teriparatide or denosumab. Outcome Measures Annualized BMD change from baseline at the lumbar spine, total hip, and femoral neck. Results Patients treated with teriparatide (n = 110) were compared with those treated with denosumab (n = 105); the mean (SD) age was 70 (10) years and median duration (interquartile range) of bisphosphonate use was 7.0 (5.6 to 9.7) years. Compared with denosumab users, teriparatide users had higher annualized BMD change at the spine by 1.3% (95% CI 0.02, 2.7%) but lower at the total hip by −2.2% (95% CI −2.9 to −1.5%) and the femoral neck by −1.1% (95% CI −2.1 to −0.1%). Those who switched to teriparatide had a transient loss of hip BMD for the first year, with no overall increase in the total hip BMD over 2 years. Conclusions Among patients who use long-term bisphosphonates, the decision of switching to teriparatide should be made with caution, especially for patients at high risk of hip fracture.

Context: O steoporosis and the increased fracture risk associated with osteoporosis become apparent in men appro ximately 10 years later than women. However, in recent studies, appro ximately 20% of healthy men in the age range 55-64 years were found to be osteopenic. Emerging data suggest a significantly increased prevalence of osteoporosis in men and women with multiple sclerosis (MS) compared to age-matched controls, but no specific clinical testing recommendations are available for men. Objective: To determine the proportion of male MS patients with osteoporosis and to identify the factors associated with the reduction in bone mass. Design: C onsecutive male MS patients seen at our MS clinic were screened with dual-X-ray absorptiometry (DEXA) scan for determining the bone mineral density (BMD). A ll patients had neurological Expanded Disability Status Scale (EDSS) evaluation. The results were compared to healthy age-matched male reference population using the Z score and to a cohort of women MS patients and women controls. C alcium, total testosterone, sex-hormone binding globulin (SHBG), 25-hydro xy-vitamin-D, and parathyroid hormone (PTH) were evaluated in male patients with decreased BMD. Relevant data on body mass index (BMI), medicatio n, alcohol consumption, smoking, and sexual dysfunction were recorded. Setting: Academic MS C entre. Patients and other participants: Forty consecutive male MS patients, age mean 51.2±8.7 years, and mean EDSS of 5.8±1.9 were evaluated with DEXA scan. O f these, 17.5% patients were relapsing - remitting (RR) MS, 57.5% were secondary progressive (SP) MS and 25% were primary progressive (PP) MS. Main outcome measure: Proportion of male MS patients with reduced BMD at the lumbar spine and femoral neck. Results: Thirty-two (80%) of our patients had a reduced bone mass of either lumbar spine or the femoral neck; of these 17 patients (42.5%) had osteopenia and 15 patients (37.5%) had osteoporosis. Twenty-o ne per cent (eight out of 38 patients) had vertebral, rib or extremities fractures. Multivariate linear regression analysis indicated that the EDSS (P B-0.0001) and BMI (P =0.0004) were the important factors associated with low BMD at the femoral neck and the EDSS was the important factor (P =0.0017) associated with low BMD at the lumbar spine. The same factors emerged as significantly associated with the corresponding Z scores, which are corrected for age and sex. No clear association between intravenous steroid therapy and BMD was evident in the multivariate analysis. Low levels of 25-hydroxy-vitamin-D were seen in 37.5% of patients. Conclusions: The proportion of male MS patients with reduced bone mass is high and disproportionate to their age and ambulation, consistent with an association between the MS disease process and patho logical bone loss. Increased awareness and bone density screening of male and female MS patients over 40 years of age is warranted.

Abstract Introduction: Teriparatide, a parathyroid hormone analog, is an important anabolic agent approved by the U.S. Food and Drug Administration to increase bone mineral density in osteoporotic patients. Parathyroid hormone (PTH) regulates calcium, phosphate, and active vitamin-D metabolites.The amino terminal peptide fragments of PTH has been known to increase bone mass and are being used in clinical practice for osteoporosis management (1). Current literature shows the efficacy of teriparatide in increasing bone density of lumbar spine and femoral neck, and decreasing the risk of vertebral and non-vertebral fractures both in postmenopausal women and men. It is also known to prevent fractures in patients with osteoporosis and promote healing of fractures (2). Case Description: A 79-year-old Hispanic female with history of osteopenia and major lumbar spine wedge compression fractures presented to our clinic for consultation. She was on ibandronate for the past four months and was having symptoms of pill esophagitis. Her last bone mineral density done on August 2017 revealed T-score of -2.5 at the lumbar spine, -1.5 at the left femoral neck, and 3.3% bone loss on the left femoral head. Rather than being started on teriparatide, zoledronic acid, or denosumab, she continued ibandronate along with calcium and vitamin D. Two months after the initial consultation, she sustained a traumatic fracture of the posterior arch and body of C2 bilaterally following a motor vehicle accident. There were discussions about starting anabolic treatment, as serial imaging did not show any significant improvement in the healing process despite the use of a collar. Two months after sustaining C2 fracture, she was started on teriparatide. Repeat cervical spine x-ray three months later showed complete healing of the C2 fracture. Discussion: There are a limited number of cases reported in regards to teriparatide induced healing of non-osteoporotic fractures (3). Our case is one of the very few reported to have shown complete radiographic and clinical healing of a traumatic, non-osteoporotic fracture after use of teriparatide for 12 weeks.

The Impact

Background: While semiannual 60 mg denosumab is a common treatment for osteoporosis, impact of monthly 120 mg denosumab, the common treatment protocol for bone metastases from solid tumors, on bone metabolism is unclear.Materials and Methods: We reviewed 15 patients with bone-metastatic prostate cancer who initiated monthly 120 mg denosumab in conjunction with androgen deprivation therapy between 2013 and 2014. Bone mineral density (BMD) was measured at lumbar spine and femoral neck using dual energy X-ray absorptiometry (DXA), before treatment and annually thereafter. Bone metabolism markers, including urine N-terminal telopeptide (uNTx) and bone type alkaline phosphatase (BAP), were monitored monthly.Results: Twelve of 15 (80%) patients had evaluable DXA before treatment, and of them, eight underwent DXA after a year of initiation without discontinuation of denosumab. Percent changes in BMD from baseline were +6.2% at lumbar spine and +7.6% at femoral neck, both of which were significant increases (both P<0.01). Bone metabolism markers were evaluable in 11 (73%) patients: uNTx decreased rapidly, while BAP declined gradually after initiating denosumab. These effects were similar to those seen by the standardized dose for osteoporosis in previous literature. There were no denosumab-related severe adverse events during the follow-up period. Conclusions: The impact of monthly 120 mg denosumab on bone metabolism was significant, but almost equivalent to that of the standard dose for osteoporosis (60mg semiannually) in bone-metastatic prostate cancer undergoing androgen deprivation therapy. Whereas the higher dose has reportedly reduced skeleton-related events, the effect on bone metabolism seemed plateaued or showed no dose-dependency.

AbstractManagement of diabetes-related foot ulceration (DFU) includes pressure offloading resulting in a period of reduced activity. The metabolic effects of this are unknown. This study aims to investigate changes in bone mineral density (BMD) and body composition 12 weeks after hospitalisation for DFU. A longitudinal, prospective, observational study of 22 people hospitalised for DFU was conducted. Total body, lumbar spine, hip and forearm BMD, and total lean and fat mass were measured by dual-energy X-ray absorptiometry (DXA) during and 12 weeks after hospitalisation for DFU. Significant losses in total hip BMD of the ipsilateral limb (− 1.7%, p < 0.001), total hip BMD of the contralateral limb (− 1.4%, p = 0.005), femoral neck BMD of the ipsilateral limb (− 2.8%, p < 0.001) and femoral neck BMD of the contralateral limb (− 2.2%, p = 0.008) were observed after 12 weeks. Lumbar spine and forearm BMD were unchanged. HbA1c improved from 75 mmol/mol (9.2%) to 64 mmol/mol (8.0%) (p = 0.002). No significant changes to lean and fat mass were demonstrated. Total hip and femoral neck BMD decreased bilaterally 12 weeks after hospitalisation for DFU. Future research is required to confirm the persistence and clinical implications of these losses.

Abstract Objective Prevention of steroidal osteoporosis is an important issue. There is no clear consensus on the impact of anti-RANKL antibody (denosumab) on BMD in patients with glucocorticoid-induced osteoporosis (GIO). In this study, we aimed to evaluate the impact of denosumab on BMD loss in patients with GIO. Methods A comprehensive systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PubMed, Web of Science and Google Scholar were used to search for original studies reported about BMD in patients with GIO treated with denosumab. In meta-analysis of BMD, the mean difference in the rate of change from baseline and the 95% CI were calculated using the random effects model. The mean differences in patients treated with denosumab were compared with those in patients treated with bisphosphonates. Results Out of 713 studies identified, seven studies met the selection criteria for the meta-analysis. At 6 and 12 months of denosumab therapy, increases in BMD were observed in the lumbar spine (2.99% [95% CI 2.71, 3.28] and 4.59% [95% CI 4.17, 5.01]), total hip (1.34% [95% CI 0.64, 2.04] and 2.16% [95% CI 2.05, 2.27]) and femoral neck (0.12% [95% CI −0.38, 0.62] and 1.55% [95% CI 0.45, 2.65]). Additionally, denosumab resulted in significant increases in BMD in the lumbar spine and femoral neck at 12 months compared with bisphosphonate therapy. Conclusion Patients with GIO experienced significant increases in BMD in response to treatment with denosumab that were detected in the lumbar spine, total hip and femoral neck at 12 months.
