Treatment of osteoporosis in men.

ABSTRACT: Aspects of osteoporosis in men, such as screening and identification strategies, definitions of diagnosis and intervention thresholds, and treatment options (both approved and in the pipeline) are discussed.Awareness of osteoporosis in men is improving, although it remains under-diagnosed and under-treated. A European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) workshop was convened to discuss osteoporosis in men and to provide a report by a panel of experts (the authors).A debate with an expert panel on preselected topics was conducted.Although additional fracture data are needed to endorse the clinical care of osteoporosis in men, consensus views were reached on diagnostic criteria and intervention thresholds. Empirical data in men display similarities with data acquired in women, despite pathophysiological differences, which may not be clinically relevant. Men should receive treatment at a similar 10-year fracture probability as in women. The design of mixed studies may reduce the lag between comparable treatments for osteoporosis in women becoming available in men.

Project description:ObjectivesTo evaluate the efficacy of treatment options to reduce osteoporotic fracture risk in men.DesignSystematic review and meta-analysis.SettingRandomized clinical trials that evaluated the efficacy of a treatment for osteoporosis or low bone mineral density for adult men and reported fracture outcomes.ParticipantsMen.MeasurementsPubMed, Embase, and the Cochrane Library databases were searched for relevant studies. Information was extracted from included studies on participant sociodemographic characteristics, number of male participants, treatment evaluated, comparator for evaluated treatment, study duration, and fracture outcomes. Risk of bias of individual studies was assessed using measures recommended by the Cochrane Collaboration.ResultsTwenty-four articles reporting results for 22 studies (including 4,868 male participants) met strict inclusion criteria. Fixed-effects meta-analyses using the Mantel-Haenszel method demonstrated significantly lower risk of vertebral fractures with alendronate (relative risk (RR) = 0.328, 95% confidence interval (CI) = 0.155-0.692) and risedronate (RR = 0.428, 95% CI = 0.245-0.746) but not with calcitonin (RR = 0.272, 95% CI = 0.046-1.608) or denosumab (RR = 0.256, 95% CI = 0.029-2.238) than in controls. For bisphosphonates as a treatment category, meta-analyses demonstrated significantly lower risk of vertebral fractures (RR = 0.368, 95% CI = 0.252-0.537) and nonvertebral fractures (RR = 0.604, 95% CI = 0.404-0.904) than in controls. The meta-analysis finding that bisphosphonates significantly reduce nonvertebral fracture risk was not robust to sensitivity analysis.ConclusionBisphosphonates reduce the risk of vertebral and possibly nonvertebral fractures for men with osteoporosis. Further studies are needed to evaluate the efficacy of bisphosphonates for reducing nonvertebral fracture risk and the efficacy of nonbisphosphonates for reducing vertebral and nonvertebral fracture risk in men with osteoporosis.

Project description:ContextIn postmenopausal women, bone mineral density (BMD) declines after teriparatide therapy is stopped. The pattern of BMD loss after teriparatide therapy is stopped in men is less clear.ObjectiveThe aim of the study was to determine whether the pattern of teriparatide-induced bone accrual and post-teriparatide bone loss differs between postmenopausal women and eugonadal men.DesignWe conducted a prospective cohort substudy.PatientsThe study included 14 postmenopausal women and 17 eugonadal men, ages 46-85 yr, with lumbar spine or femoral neck BMD T-scores below -2.InterventionTeriparatide (37 microg sc daily) was administered for 24 months, followed by 12 months off therapy.Main outcome measuresWe measured BMD at various anatomic sites by dual-energy x-ray absorptiometry, trabecular spine BMD by quantitative computed tomography, and bone turnover markers during the treatment and observation periods. The response to teriparatide administration and discontinuation was compared between females and males.ResultsBMD of the spine, femoral neck, total hip, and trabecular spine increased similarly during the treatment period in men and women, whereas BMD at the radius was stable in men but decreased by 8.1 +/- 3.3% in women (P < 0.0001). After teriparatide was stopped, BMD at the posterior-anterior spine decreased by 7.1 +/- 3.8% in women and by 4.1 +/- 3.5% in men (P = 0.036). BMD at the total hip and femoral neck decreased by 3.8 +/- 3.9 and 3.1 +/- 4.3%, respectively, in women but remained stable in men (P < 0.05 for both sites). BMD at the distal radius remained stable in men but increased in women by 1.6 +/- 3.1% (P = 0.069).ConclusionsTeriparatide appears to increase BMD similarly in postmenopausal women and eugonadal men with osteoporosis. After teriparatide is stopped, the decline in BMD is greater in women than in men. If confirmed in larger cohorts, these findings would suggest that the indication for immediate antiresorptive therapy after teriparatide may not be as urgent in men as in women.

Project description:Osteoporosis affects many men, with significant morbidity and mortality. However, the best osteoporosis screening strategies for men are unknown. We developed an individual-level state-transition cost-effectiveness model with a lifetime time horizon to identify the cost-effectiveness of different osteoporosis screening strategies for US men involving various screening tests (dual-energy X-ray absorptiometry [DXA]; the Osteoporosis Self-Assessment Tool [OST]; or a fracture risk assessment strategy using age, femoral neck bone mineral density [BMD], and Vertebral Fracture Assessment [VFA]); screening initiation ages (50, 60, 70, or 80 years); and repeat screening intervals (5 years or 10 years). In base-case analysis, no screening was a less effective option than all other strategies evaluated; furthermore, no screening was more expensive than all strategies that involved screening with DXA or the OST risk assessment instrument, and thus no screening was "dominated" by screening with DXA or OST at all evaluated screening initiation ages and repeat screening intervals. Screening strategies that most frequently appeared as most cost-effective in base-case analyses and one-way sensitivity analyses when assuming willingness-to-pay of $50,000/quality-adjusted life-year (QALY) or $100,000/QALY included screening initiation at age 50 years with the fracture risk assessment strategy and repeat screening every 10 years; screening initiation at age 50 years with fracture risk assessment and repeat screening every 5 years; and screening initiation at age 50 years with DXA and repeat screening every 5 years. In conclusion, expansion of osteoporosis screening for US men to initiate routine screening at age 50 or 60 years would be expected to be effective and of good value for improving health outcomes. A fracture risk assessment strategy using variables of age, femoral neck BMD, and VFA is likely to be the most effective of the evaluated strategies within accepted cost-effectiveness parameters. DXA and OST are also reasonable screening options, albeit likely slightly less effective than the evaluated fracture risk assessment strategy. © 2016 American Society for Bone and Mineral Research.

Project description:BackgroundIt is generally believed that Thai people do not suffer from hypovitaminosis D because there is abundant sunlight throughout the year, and that taking vitamin D supplements could result in abnormally high levels of vitamin D. This is a Thai FDA-driven study to investigate this risk over a period of 26 weeks of taking alendronate sodium/vitamin D3 combination tablets.MethodsOsteoporosis patients in Thailand were recruited to a multicenter, open-label, 6-month trial of oral alendronate sodium 70 mg/vitamin D3 5600 IU. Patients received study medication once a week for 26 weeks. Serum 25-hydroxyvitamin D (25(OH)D) and Beta-CrossLaps (β-CTx) levels were measured at baseline and 26 weeks. The primary endpoint was the proportion of patients with 25(OH)D ≥ 50 ng/mL at week 26; it was hypothesized that 26 weeks' treatment would not result in 25(OH)D serum levels ≥ 50 ng/mL in > 7% of osteoporosis patients.ResultsOne hundred ninety-eight patients were recruited. At baseline, 67.2% of the patients had 25(OH)D < 30 ng/mL; this declined to 34.4% by week 26. The mean 25(OH)D level improved from 27.8 ng/mL at baseline to 33.6 ng/mL at week 26. Five patients (2.69% of the full analysis set) had 25(OH)D levels ≥ 50 ng/mL at 26 weeks. The highest 25(OH)D level, 64.3 ng/mL, was observed in a patient whose baseline level was 102.2 ng/mL. The majority (62.9%) of the patients had optimal 25(OH)D levels (30-50 ng/mL). β-CTx levels were reduced by 57.7% after 26 weeks' treatment. No clinically significant cases of hypercalcemia which could be associated with hypervitaminosis D were identified during physical examination, in vital signs, or in laboratory results. Overall, 73 patients (36.9%) reported at least one adverse event (AE), with 13 (6.6%) reporting drug-related AEs. Four patients discontinued due to AEs, two of which were drug-related. Serious AEs were reported for four patients, of which one was considered drug-related.ConclusionsOral alendronate sodium 70 mg plus vitamin D3 5600 IU once weekly had an acceptable safety profile in this study, and increased serum 25(OH)D and reduced β-CTx levels in osteoporosis patients. This treatment improved 25(OH)D levels, without causing abnormally high levels, after 26 weeks' treatment.Trial registrationClinical Trials.gov NCT01437111 , Registered September 19, 2011.

Project description:BackgroundAdherence to anti-osteoporosis treatments is poor, exposing treated women to increased fracture risk. Determinants of poor adherence are poorly understood. The study aims to determine physician- and patient- rated treatment compliance with osteoporosis treatments and to evaluate factors influencing compliance.MethodsThis was an observational, cross-sectional pharmacoepidemiological study with a randomly-selected sample of 420 GPs, 154 rheumatologists and 110 gynaecologists practicing in France. Investigators included post-menopausal women with a diagnosis of osteoporosis and a treatment initiated in the previous six months. Investigators completed a questionnaire on clinical features, treatments and medical history, and on patient compliance. Patients completed a questionnaire on sociodemographic features, lifestyle, attitudes and knowledge about osteoporosis, treatment compliance, treatment satisfaction and quality of life. Treatment compliance was evaluated with the Morisky Medication-taking Adherence Scale. Variables collected in the questionnaires were evaluated for association with compliance using multivariate logistic regression analysis.Results785 women were evaluated. Physicians considered 95.4% of the sample to be compliant, but only 65.5% of women considered themselves compliant. The correlation between patient and physician perceptions of compliance was low (?: 0.11 [95% CI: 0.06 to 0.16]). Patient-rated compliance was highest for monthly bisphosphonates (79.7%) and lowest for hormone substitution therapy (50.0%). Six variables were associated with compliance: treatment administration frequency, perceptions of long-term treatment acceptability, perceptions of health consequences of osteoporosis, perceptions of knowledge about osteoporosis, exercise and mental quality of life.ConclusionCompliance to anti-osteoporosis treatments is poor. Reduction of dosing regimen frequency and patient education may be useful ways of improving compliance.
