Osteoporosis

What information can the lay public find about osteoporosis treatment? A descriptive study coding the content and quality of bisphosphonate information on the internet

Abstract

Summary

Despite its effectiveness, bisphosphonate use for osteoporosis is low. We assessed bisphosphonate information on the internet and found the most commonly listed benefits/risks were bone density loss, gastrointestinal issues, and jaw necrosis, that risk quantification was rare, and information quality varied. Findings underscore the importance of clinical communication about bisphosphonates.

Introduction

The US Preventative Services Task Force recommends osteoporosis screening and treatment with bisphosphonates in high-risk populations. However, bisphosphonate use among individuals with osteoporosis remains low. The content and quality of information from outside sources may influence individuals' bisphosphonate decisions. Therefore, we sought to assess the content and quality of osteoporosis treatment information available to the public by conducting an internet search and coding available bisphosphonate information.

Methods

Eleven search terms about osteoporosis and bisphosphonates were entered into four search engines. Two raters assessed websites for information about bisphosphonates, whether and how benefits and side effects were described and quantified, contraindications, and dosing instructions. Coders also assessed website interface and slant/balance of information.

Results

One thousand four hundred seventy-three websites were identified. Two hundred twenty-seven websites met inclusion criteria and were coded. The most common bisphosphonate benefit described was prevention of bone density loss (77.1% of websites). The most common side effects described were gastrointestinal problems (66.1%) and jaw osteonecrosis (58.6%). Most websites did not quantify bisphosphonate benefits (78.0%) or side effects (82.4%). Complementary/integrative health websites (p < .001) and pharmaceutical litigation websites (p < .001) were more often slanted against taking bisphosphonates, compared to all websites coded. General medical knowledge websites were more balanced than other websites (p = .023).

Conclusions

The quality of bisphosphonate information on the internet varies substantially. Providers counseling patients about osteoporosis treatment should inquire about patients' baseline bisphosphonate knowledge. Providers can complement accurate information and address potential bisphosphonate misconceptions.

Multiple vertebral compression fractures after sleeve gastrectomy and a subsequent pregnancy: a case report

Abstract

We report that a 33-year-old woman developed multiple compression fractures several years after a sleeve gastrectomy followed by pregnancy. Despite normal areal BMD values assessed by dual-energy X-ray absorptiometry and no family history of osteoporosis, the patient demonstrated low lumbar spine trabecular bone score, as well as low peripheral trabecular volumetric BMD and deterioration of trabecular microarchitecture assessed by high-resolution peripheral quantitative computed tomography. Women of reproductive age should be provided with lifestyle management targeting bone health following bariatric surgery.



Association between serum uric acid and bone health in adolescents

Abstract

Summary

Previous studies are suggestive of the protective role of uric acid on bone in the middle-aged and elderly. Whether this association exists in younger individuals has not been examined. This investigation showed a significant positive association between serum uric acid and bone parameters among Iranian adolescents.

Introduction

Uric acid (UA) might be linked to bone health, but it is unclear whether its effects on bone are limited to certain population subgroups. This study is aimed at investigating the correlation between serum uric acid levels and bone mineral density (BMD) in Iranian adolescents.

Methods

This cross-sectional study was conducted on 413 (221 girls and 192 boys) Iranian adolescents aged 9–19 years. An analysis of anthropometric, biochemical parameters and bone density was performed on the participants. Measurements included serum uric acid, calcium, phosphorus, alkaline phosphatase, albumin, and vitamin D. They were divided according to their serum UA into the low UA group who had UA ≤ 6 mg/dL and the high UA group with UA > 6 mg/dL. BMD and bone mineral content (BMC) were measured in the total body, lumbar spine, and left femoral neck, using dual energy X-ray absorptiometry (DXA), and bone mineral apparent density (BMAD) was calculated.

Results

A Pearson correlation analysis revealed a significant correlation between UA and bone parameters. In multiple regression analyses adjusted for potential confounders, serum UA was proven to be associated with BMD and BMC at all sites. There was no association between UA, serum calcium, and vitamin D concentrations.

Conclusion

Our study, as the first research on adolescents, demonstrated a higher bone density in those who had higher UA levels.



History of cardiovascular disease and cardiovascular biomarkers are associated with 30-day mortality in patients with hip fracture

Abstract

Summary

Hip fractures are associated with increased mortality and it is important to identify risk factors. This study demonstrates that preexisting cardiovascular disease as well as cardiovascular biomarkers that are associated with increased 30-day mortality. These findings can be used to identify high-risk patients who might benefit from specialized care.

Introduction

This study investigates the association between cardiovascular disease (CVD), cardiovascular biomarkers, and 30-day mortality following a hip fracture.

Methods

The Danish National Patient Registry was used to investigate the association between CVD and mortality following hip fracture in a nationwide population-based cohort study. In a subset of the included patients (n = 355), blood samples were available from a local biobank. These samples were used for analyzing the association between specific biochemical markers and mortality. The primary outcome was 30-day mortality.

Results

A total of 113,211 patients were included in the population-based cohort study. Among these, heart failure was present in 9.4%, ischemic heart disease in 15.9%, and ischemic stroke in 12.0%. Within 30 days after the hip fracture, 11,488 patients died, resulting in an overall 30-day mortality of 10.1%. The 30-day mortality was significantly increased in individuals with preexisting CVD with multivariably adjusted odds ratios of 1.69 (95% confidence interval, 1.60–1.78) for heart failure, 1.23 (1.17–1.29) for ischemic heart disease, and 1.06 (1.00–1.12) for ischemic stroke. In the local database including 355 patients, 41 (11.5%) died within 30 days. The multivariably adjusted odds ratio for 30-day mortality increased with increasing NT-proBNP (2.36 [1.53–3.64] per quartile) and decreased with increasing HDL cholesterol (0.58 [0.41–0.82] per quartile). On this basis, we established a model for predicting the probability of death based on the biochemical markers.

Conclusion

Preexisting CVD was associated with increased 30-day mortality after a hip fracture. Furthermore, high levels of NT-proBNP and low levels of HDL cholesterol were associated with increased 30-day mortality.



Cost-effectiveness of pharmacological fracture prevention for osteoporosis as prescribed in clinical practice in France, Germany, Italy, Spain, and the United Kingdom

Abstract

Summary

This study estimated the cost-effectiveness of pharmacological fracture prevention as prescribed in the five largest European countries (EU5) using the IOF reference cost-effectiveness model. Pharmacological fracture prevention as prescribed in clinical practice was cost-saving (provided more QALYs at lower costs) compared to no treatment in each of the EU5.

Purpose

To estimate the real-world cost-effectiveness of pharmacological fracture prevention as prescribed in the five largest European countries by population size: France, Germany, Italy, Spain, and the United Kingdom (UK) (collectively EU5).

Materials and methods

We analyzed sales data on osteoporosis drugs in each of the EU5 to derive a hypothetical intervention that corresponds to the mix of osteoporosis medication prescribed in clinical practice. The costs for this treatment mix were obtained directly from the sales data, and the efficacy of the treatment mix was estimated by weighing the treatment-specific fracture risk reductions from a published meta-analysis. Subsequently, we estimated the cost-effectiveness using costs per quality adjusted life year (QALY) of the intervention compared to no treatment in each of the EU5 using the International Osteoporosis Foundation (IOF) reference cost-effectiveness model. The model population comprised postmenopausal women, mean age 72 years with established osteoporosis (T-score ≤ − 2.5) among whom 23.6% had a prevalent vertebral fracture. The model was populated with country-specific data from the literature.

Results

Pharmacological fracture prevention as prescribed in clinical practice was cost-saving (provided more QALYs at lower costs) compared to no treatment in each country. The findings were robust in scenario analyses.

Conclusions

Pharmacological fracture prevention as prescribed in clinical practice is cost-saving in each of the EU5. Because of the under-diagnosis and under-treatment of post-menopausal osteoporosis, from a health economic perspective, further cost-savings may be reached by expanding treatment to those at increased risk of fracture currently not receiving any treatment.



A population-based study of postfracture care in Manitoba, Canada 2000/2001–2014/2015

Abstract

Summary

We previously found that population-based postfracture notification, which informed primary care physicians of their patient's recent fracture and suggested assessment for osteoporosis, led to an improvement in postfracture care in the context of a randomized controlled trial (ClinicalTrials.gov identifier NCT00594789, fractures from late 2007 to mid-2010). Since June 2010, a province-wide postfracture notification program was implemented. This study was to (1) determine whether this program has resulted in sustained improvement in postfracture care and (2) test factors associated with receiving osteoporosis care.

Methods

A retrospective matched cohort study was performed using population-based health administrative data in Manitoba, Canada. We selected individuals aged 50+ years with an incident major osteoporosis fracture (MOF; N = 18,541) in fiscal years 2000/2001 to 2013/2014 and controls without a MOF (N = 92,705) matched (5:1) on age, sex, and residential area. The Cochran-Armitage test tested for a linear trend in osteoporosis care outcomes for cases and controls. Logistic regressions were used to test characteristics associated with the likelihood of receiving osteoporosis care.

Results

The percentage of individuals receiving DXA testing and/or osteoporosis medication increased in fracture cases (p < 0.001), but decreased in controls (p < 0.001). Odds ratios for osteoporosis care in years following the postfracture notification program were approximately double of those prior to the clinical trial. In addition to prior MOF (OR 9.03, 95% CI 8.60–9.48), factors associated with osteoporosis care included lower income (OR   0.72, 95% CI 0.67–0.78), glucocorticoid use (OR   4.37, 95% CI 3.72–5.14), diabetes diagnosis (OR =  0.74, 95% CI 0.68–0.80), and Charlson Comorbidity Index (indexes 1–2: OR 1.27, 95% CI 1.20–1.34; indexes 3–5: OR 1.26, 95% CI 1.13–1.40).

Conclusions

Adopting a population-based postfracture notification program led to sustained improvements in postfracture care.
