Osteoporosis

An intervention designed to prevent serious fall injuries among older adults was less effective than researchers expected but did identify important ways for clinicians to help, including screening all older patients for fall risk and deprescribing certain medications when possible.

The study was conducted by Shalender Bhasin, MD, MBBS, from Brigham and Women’s Hospital and Harvard Medical School in Boston and colleagues on behalf of the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) trial investigators and was published online July 8 in The New England Journal of Medicine.

Patients are often unaware of their increased risk until they have fallen for the first time, and they often underestimate how many of their risk factors can be improved, Dr. Bhasin said in an interview.

“Fall injuries are a very important cause of injury-related deaths among older adults, and these are preventable. Yet they are so difficult; for 30 years the rates of fall injuries have not declined,” he said.

Using a pragmatic, cluster-randomized trial, the researchers studied the clinical effectiveness of a “patient-centered intervention that combined elements of practice redesign (reconfiguration of workflow to improve quality of care) and an evidence-based, multifactorial, individually tailored intervention implemented by specially trained nurses in primary care settings,” the authors explained.

Participants in the intervention group worked with trained nurses (fall care managers) to identify their risk factors and determine which risks they wanted to modify. Participants in the control group received their typical care and a pamphlet with information on falls and were encouraged to talk with their primary care physicians (who received the results on risk factor screening) about fall prevention. Those in the intervention group also received the pamphlet.

Fall care managers evaluated patients’ home environments and in some cases visited the patient’s home, Dr. Bhasin said.

The researchers enrolled community-dwelling adults aged 70 years or older who were at higher risk for fall injuries from 86 primary care practices across 10 U.S. health care systems. Half of the practices were randomly assigned to provide the intervention to their patients; the other half of the practices provided enhanced usual care.

The researchers defined patients with increased risk for fall injuries as those who had suffered a fall-related injury at least twice during the previous year or those whose difficulties with balance or walking made them fearful of falling. Serious fall injuries were defined as falls that cause a fracture (other than a thoracic or lumbar vertebral fracture), joint dislocation, a cut needing closure, or falls that resulted in hospital admission for a “head injury, sprain or strain, bruising or swelling, or other serious injury,” they explained.

Demographic and baseline characteristics were similar for both groups of patients (mean age, 80 years; 62.0% women); 38.9% had experienced a fall-related injury during the previous year, and 35.1% had suffered at least two falls during the previous year.

The researchers hypothesized that serious fall injuries would be 20% lower in the intervention group, compared with the control group, but that was not the case.

The findings showed no significant difference between the intervention group (4.9 events per 100 person-years of follow-up) and the control group (5.3 events per 100 person-years of follow-up) for the rate of first adjudicated serious fall injury (hazard ratio, 0.92; P = .25). Results were similar in a practice-level analysis and a sensitivity analysis adjusted for participant-level covariates.

However, there was a difference in rates of first participant-reported fall injury, which was a secondary endpoint, at 25.6 events per 100 person-years of follow-up among participants in the intervention group versus 28.6 events among those in the control group (HR, 0.90; P = .004).

There were no significant differences between the groups for rates of all adjudicated serious fall injuries and all patient-reported fall injuries. Bone fractures and injuries resulting in hospitalization were the most frequent types of adjudicated serious fall injuries.

Rates of serious adverse events resulting in hospitalization were similar for the intervention group and the control group (32.8 and 33.3 hospitalizations per 100 person-years of follow-up, respectively), as well as rates of death (3.3 deaths per 100 person-years of follow-up in both groups).
 

Simple steps can help

“The most important thing clinicians can do is a quick screen for fall injury risk,” Dr. Bhasin said in an interview. The screening tool he uses consists of three questions and can be completed in less than a minute. Clinicians should share that information with patients, he continued.

“Just recognizing that they are at risk for falls, patients are much more motivated to take action,” Dr. Bhasin added.

The top three risk factors identified among trial participants were trouble with strength, gait, or balance; osteoporosis or vitamin D deficiency; and impaired vision. “The use of certain medications, postural hypotension, problems with feet or footwear, and home safety hazards were less commonly identified, and the use of certain medications was the least commonly prioritized,” the authors wrote.

It is vital that clinicians help patients implement changes, Dr. Bhasin said. He noted that many patients encounter barriers that prevent them from taking action, including transportation or insurance problems and lack of access to exercise programs in the community.

Deprescribing medications such as sleep medications and benzodiazepines is also a key piece of the puzzle, he added. “They’re pretty huge risks, and yet it is so hard to get people off these medications.”

Future research will focus on how to improve the intervention’s effectiveness and also will test the strategy among those with cognitive impairments who have even higher risk for fall injuries, Dr. Bhasin said.
 

Falls remain common

A report published online July 9 in Morbidity and Mortality Weekly Report underscores the prevalence of fall-related injuries: In 2018, more than one quarter (27.5%) of adults 65 years or older said they had fallen at least once during the previous year (35.6 million falls), and 10.2% said they had experienced a fall-related injury (8.4 million fall-related injuries). The percentage of adults who reported a fall increased during 2012-2016, then decreased during 2016-2018.

Briana Moreland, MPH, from Synergy America and the Division of Injury Prevention at National Center for Injury Prevention and Control of the Centers for Disease Control and Prevention and colleagues wrote that older adults and health care providers can work together to reduce fall risk.

“CDC created the Stopping Elderly Accidents, Deaths and Injuries (STEADI) initiative, which offers tools and resources for health care providers to screen their older patients for fall risk, assess modifiable fall risk factors, and to intervene with evidence-based fall prevention interventions (https://www.cdc.gov/steadi). These include medication management, vision screening, home modifications, referral to physical therapists who can address problems with gait, strength, and balance, and referral to effective community-based fall prevention programs,” Ms. Moreland and colleagues explain.

Dr. Bhasin has received grants from the National Institute on Aging (NIA) and Patient-Centered Outcomes Research Institute (PCORI) during the conduct of the study. He has received grants, personal fees, and nonfinancial support from AbbVie; grants from Transition Therapeutics, Alivegen, and Metro International Biotechnology; and personal fees from OPKO outside the submitted work. A coauthor received grants from the NIA and PCORI during the conduct of the study and is co-owner of Lynx Health, and another Peduzzi received grants and other compensation from NIA-PCORI during the conduct of the study. Two other authors have disclosed no relevant financial relationships. The remaining authors report a variety of relevant financial relationships; a complete list is available on the journal’s website.

A new study has determined a benefit of cardiac CT scans beyond assessing heart health: Evaluating fracture rate and potential osteoporosis through the bone mineral density (BMD) of thoracic vertebrae.

“Our results represent a step toward appraisal and recognition of the clinical utility of opportunistic BMD screening from cardiac CT,” wrote Josephine Therkildsen, MD, of Hospital Unit West in Herning, Denmark, and coauthors. The study was published July 14 in Radiology.

To determine if further analysis of cardiac CT could help determine BMD and its association with fracture rate, the investigators launched a prospective observational study of 1,487 Danish patients with potential coronary artery disease who underwent cardiac CT scans between September 2014 and March 2016. Their mean age was 57 years (standard deviation, 9; range, 40-80). Nearly all of the patients were white, and 52.5% (n = 781) were women.

All participants underwent a noncontrast-enhanced cardiac CT, from which volumetric BMD of three thoracic vertebrae was measured via commercially available semiautomatic software. Their mean BMD was 119 mg/cm³ (SD, 34) with no significant difference noted between male and female patients. Of the 1,487 participants, 695 were defined as having normal BMD (> 120 mg/cm³), 613 as having low BMD (80-120 mg/cm³), and 179 as having very low BMD (< 80 mg/cm³). Median follow-up was 3.1 years (interquartile range, 2.7-3.4).

Incident fracture occurred in 80 patients (5.4%), of whom 48 were women and 32 were men. Patients who suffered fractures were significantly older than patients with no fractures (mean 59 years vs. 57 years; P = .03). Of the 80 patients with fractures, 31 were osteoporosis related.

In an unadjusted analysis, participants with very low BMD had a greater rate of any fracture (hazard ratio [HR], 2.6; 95% confidence interval, 1.4-4.7; P = .002) and of osteoporosis-related fracture (HR, 8.1; 95% CI, 2.4-27.0; P = .001). After adjustment for age and sex, their rates remained significantly greater for any fracture (HR, 2.1; 95% CI, 1.1-4.2; P = .03) and for osteoporosis-related fracture (HR, 4.0; 95% CI, 1.1-15.0; P = .04).

“Opportunistic” use of scans benefits both physicians and patients

“The concept of using a CT scan that was done for a different purpose allows you to be opportunistic,” Ethel S. Siris, MD, the Madeline C. Stabile Professor of Clinical Medicine in the department of medicine at Columbia University and director of the Toni Stabile Osteoporosis Center of the Columbia University Medical Center, New York–Presbyterian Hospital, New York, said in an interview. “If you’re dealing with older patients, and if you have the software for your radiologist to use to reanalyze the CT scan and say something about the bone, it’s certainly a way of estimating who may be at risk of future fractures.

“From a practical point of view, it’s hard to imagine that it would ever replace conventional bone mineral density testing via DXA [dual-energy x-ray absorptiometry],” she added. “That said, osteoporosis is woefully underdiagnosed because people don’t get DXA tested. This study showed that, if you have access to the scan of the thoracic or even the lumbar spine and if you have the necessary software, you can make legitimate statements about the numbers being low or very low. What that would lead to, I would hope, is some internists to say, ‘This could be a predictor of fracture risk. We should put you on treatment.’ And then follow up with a conventional DXA test.

“Is that going to happen? I don’t know. But the bottom line of the study is: Anything that may enhance the physician’s drive to evaluate a patient for fracture risk is good.”
 

Whatever the reason for the scan, CT can help diagnose osteoporosis

This study reinforces that CT exams – of the chest, in particular – can serve a valuable dual purpose as osteoporosis screenings, Miriam A. Bredella, MD, professor of radiology at Harvard Medical School and vice chair of the department of radiology at Massachusetts General Hospital, Boston, wrote in an accompanying editorial.

“In the United States, more than 80 million CT examinations are performed each year, many of which could be used to screen for osteoporosis without additional costs or radiation exposure,” she wrote. And thanks to the findings of the study by Therkildsen et al., which relied on both established and new BMD thresholds, the link between thoracic spine BMD and fracture risk is clearer than ever.

“I hope this study will ignite interest in using chest CT examinations performed for other purposes, such as lung cancer screening, for opportunistic osteoporosis screening and prediction of fractures in vulnerable populations,” she added.

The authors acknowledged their study’s limitations, including a small number of fracture events overall and the inability to evaluate associations between BMD and fracture rate at specific locations. In addition, their cohort was largely made up of white participants with a certain coronary artery disease risk profile; because of ethnical differences in BMD measurements, their results “cannot be extrapolated to other ethnical groups.”

Several of the study’s authors reported potential conflicts of interest, including receiving grants and money for consultancies and board memberships from various councils, associations, and pharmaceutical companies. Dr. Bredella reported no conflicts of interest. Dr. Siris has no relevant disclosures.

Their mean age was 57 years (standard deviation, 9; range, 40-80). Nearly all of the patients were white, and 52.5% (n = 781) were women.

All participants underwent a noncontrast-enhanced cardiac CT, from which volumetric BMD of three thoracic vertebrae was measured via commercially available semiautomatic software. Their mean BMD was 119 mg/cm³ (SD, 34) with no significant difference noted between male and female patients. Of the 1,487 participants, 695 were defined as having normal BMD (> 120 mg/cm³), 613 as having low BMD (80-120 mg/cm³), and 179 as having very low BMD (< 80 mg/cm³). Median follow-up was 3.1 years (interquartile range, 2.7-3.4).

Incident fracture occurred in 80 patients (5.4%), of whom 48 were women and 32 were men. Patients who suffered fractures were significantly older than patients with no fractures (mean 59 years vs. 57 years; P = .03). Of the 80 patients with fractures, 31 were osteoporosis related.

In an unadjusted analysis, participants with very low BMD had a greater rate of any fracture (hazard ratio [HR], 2.6; 95% confidence interval, 1.4-4.7; P = .002) and of osteoporosis-related fracture (HR, 8.1; 95% CI, 2.4-27.0; P = .001). After adjustment for age and sex, their rates remained significantly greater for any fracture (HR, 2.1; 95% CI, 1.1-4.2; P = .03) and for osteoporosis-related fracture (HR, 4.0; 95% CI, 1.1-15.0; P = .04).

“Opportunistic” use of scans benefits both physicians and patients

“The concept of using a CT scan that was done for a different purpose allows you to be opportunistic,” Ethel S. Siris, MD, the Madeline C. Stabile Professor of Clinical Medicine in the department of medicine at Columbia University and director of the Toni Stabile Osteoporosis Center of the Columbia University Medical Center, New York–Presbyterian Hospital, New York, said in an interview. “If you’re dealing with older patients, and if you have the software for your radiologist to use to reanalyze the CT scan and say something about the bone, it’s certainly a way of estimating who may be at risk of future fractures.

“From a practical point of view, it’s hard to imagine that it would ever replace conventional bone mineral density testing via DXA [dual-energy x-ray absorptiometry],” she added. “That said, osteoporosis is woefully underdiagnosed because people don’t get DXA tested. This study showed that, if you have access to the scan of the thoracic or even the lumbar spine and if you have the necessary software, you can make legitimate statements about the numbers being low or very low. What that would lead to, I would hope, is some internists to say, ‘This could be a predictor of fracture risk. We should put you on treatment.’ And then follow up with a conventional DXA test.

“Is that going to happen? I don’t know. But the bottom line of the study is: Anything that may enhance the physician’s drive to evaluate a patient for fracture risk is good.”
 

Whatever the reason for the scan, CT can help diagnose osteoporosis

This study reinforces that CT exams – of the chest, in particular – can serve a valuable dual purpose as osteoporosis screenings, Miriam A. Bredella, MD, professor of radiology at Harvard Medical School and vice chair of the department of radiology at Massachusetts General Hospital, Boston, wrote in an accompanying editorial.

“In the United States, more than 80 million CT examinations are performed each year, many of which could be used to screen for osteoporosis without additional costs or radiation exposure,” she wrote. And thanks to the findings of the study by Therkildsen et al., which relied on both established and new BMD thresholds, the link between thoracic spine BMD and fracture risk is clearer than ever.

“I hope this study will ignite interest in using chest CT examinations performed for other purposes, such as lung cancer screening, for opportunistic osteoporosis screening and prediction of fractures in vulnerable populations,” she added.

The authors acknowledged their study’s limitations, including a small number of fracture events overall and the inability to evaluate associations between BMD and fracture rate at specific locations. In addition, their cohort was largely made up of white participants with a certain coronary artery disease risk profile; because of ethnical differences in BMD measurements, their results “cannot be extrapolated to other ethnical groups.”

Several of the study’s authors reported potential conflicts of interest, including receiving grants and money for consultancies and board memberships from various councils, associations, and pharmaceutical companies. Dr. Bredella reported no conflicts of interest. Dr. Siris has no relevant disclosures.

Six medical societies from across the globe are emphasizing the importance of individuals obtaining the daily recommended dose of vitamin D, especially given the impact of the COVID-19 pandemic on outdoor time.

The statement, “Joint Guidance on Vitamin D in the Era of COVID-19,” is supported by the American Society for Bone and Mineral Research, the Endocrine Society, and the American Association of Clinical Endocrinologists, among others.

They felt the need to clarify the recommendations for clinicians. Central to the guidance is the recommendation to directly expose the skin to sunlight for 15-30 minutes per day, while taking care to avoid sunburn.

The statement noted that “vitamin D is very safe when taken at reasonable dosages and is important for musculoskeletal health. Levels are likely to decline as individuals reduce outside activity (sun exposure) during the pandemic.”

It added that “most older and younger adults can safely take 400-1000 IU daily to keep vitamin D levels within the optimal range as recommended by [the US] Institute of Medicine guidelines.”

The statement also noted that the scientific evidence clearly supports the benefits that vitamin D (in combination with calcium intake) plays in building a strong skeleton and preventing bone loss.

Other societies supporting the statement are the European Calcified Tissue Society, the National Osteoporosis Foundation, and the International Osteoporosis Foundation.

What role for vitamin D in COVID-19?

Over recent months, the role of vitamin D in relation to prevention of COVID-19 has been the subject of intense debate. Now, these societies have joined forces and endorsed evidence-based guidance to clarify the issue around obtaining the daily recommended dosage of vitamin D.

During the pandemic, orders to stay at home meant individuals were likely to spend less time outdoors and have less opportunity to draw their vitamin D directly from sunlight, which is its main source, other than a limited number of foods or as a dietary supplement, the societies explained.

However, they acknowledged that the role of vitamin D in COVID-19 remains unclear.

“The current data do not provide any evidence that vitamin D supplementation will help prevent or treat COVID-19 infection; however, our guidance does not preclude further study of the potential effects of vitamin D on COVID-19,” the joint statement said.

Research to date suggests that vitamin D may play a role in enhancing the immune response, and given prior work demonstrating a role for the activated form of vitamin D – 1,25(OH)2D – in immune responses, “further research into vitamin D supplementation in COVID-19 disease is warranted,” it added. “Trials to date have been observational and there have been no randomized, controlled trials from which firm conclusions about causal relationships can be drawn. Observational studies suggest associations between low vitamin D concentrations and higher rates of COVID-19 infection.”

Medscape Medical News previously reported on the existing observational data regarding vitamin D in COVID-19. A recent rapid evidence review by the National Institute for Health and Care Excellence failed to find any evidence that vitamin D supplementation reduces the risk or severity of COVID-19.

Although the adverse effects of systemic glucocorticoids (GCs) are well known, their association with hypertension in rheumatoid arthritis (RA) has been unclear. Now, a large population-based study shows that the drugs are linked to a 17% overall increased risk for incident hypertension among patients with RA.

Further, when the researchers stratified participants by dose category, they found that doses higher than 7.5 mg were significantly associated with hypertension. Cumulative dosage was not tied to any clear pattern of risk.

The authors, led by Ruth E. Costello, a researcher at the Centre for Epidemiology Versus Arthritis in the Centre for Musculoskeletal Research at the University of Manchester (England) concluded that patients who are taking these drugs for the treatment of RA should be monitored for high blood pressure, which is an important but modifiable cardiovascular risk factor, and treated appropriately.

The results of Ms. Costello and colleagues’ study were published June 27 in Rheumatology.

“While fractures associated with these steroid drugs are well studied, hypertension is a side effect that seems to have been less well studied, and yet it is an important cardiovascular risk factor that can be managed,” Ms. Costello said in an interview.

To better understand the possible association, Ms. Costello and colleagues identified 17,760 patients who were newly diagnosed with RA between 1992 and 2019 and were included in the Clinical Practice Research Datalink, which represents about 7% of the U.K. population. None of the patients had hypertension at initial RA diagnosis. Slightly more than two-thirds were women (68.1%), and the mean age was 56.3 years.

Of those patients, 7,421 (41.8%) were prescribed GCs during postdiagnosis follow-up. Most patients (73%) were followed for at least 2 years.

Patients who used GCs were slightly older than never-users (mean age, 57.7 vs. 55.3 years), were predominantly women, had a history of smoking, and had more comorbidities.

The overall incidence rate (IR) of hypertension was 64.1 per 1,000 person-years (95% confidence interval, 62.5-65.7). There were 6,243 cases of incident hypertension over 97,547 person-years of follow-up.

Among those exposed to GCs, 1,321 patients developed hypertension, for an IR of 87.6 per 1,000 person-years. Among unexposed participants, the IR for hypertension was 59.7 per 1,000 person-years. In Cox proportional hazards modeling, GC use was associated with a 17% increased risk for hypertension (hazard ratio, 1.17; 95% CI, 1.10-1.24).

The researchers noted that 40% of GC users with hypertension were not prescribed an antihypertensive agent at any point during the study. “Whilst some may have been offered lifestyle advice, left untreated this has important implications in terms of addressing modifiable risk factors in an RA population already at increased risk of CV disease,” they wrote.

They noted that cardiovascular disease is a major driver of the elevated mortality risk seen among adults with RA compared with the general population and that recent treatment recommendations address management of cardiovascular risks in these patients.

“There are several routes by which GCs may promote cardiovascular disease, including hypertension, metabolic changes, diabetes, and weight gain. We don’t currently know the extent to which each of these individual mechanisms may be increasing cardiovascular disease,” said Ms. Costello.

“Glucocorticoids increase fluid retention and promote obesity and hypertension,” said Rajat S. Bhatt, MD, a rheumatologist at Prime Rheumatology and Memorial Hermann Katy Hospital in Richmond, Texas, who sees hypertension in GC users in his clinical practice. “So patients need to be monitored for these risk factors,” he said in an interview.

Although hypertension may be a significant factor in the increase in cardiovascular disease in the RA population, Dr. Bhatt said the major driver is likely the intrinsic inflammatory state caused by the disease itself. As to why the GC-hypertension connection has flown under the radar in RA, he added, “That specific link has been difficult to tease out since RA patients are often on multiple medications.”

In regard to the role of dosage, Dr. Bhatt said that hypertension risk increases with higher GC doses, as the U.K. study indicates, and usually subsides when patients stop using GCs.

“Whether the observed dose association is causal or influenced by the underlying disease severity, our results suggest we should be vigilant in patients on all doses of GC, especially higher doses,” Ms. Costello added.

In regard to using drugs that are less cardiotoxic than GCs, Dr. Bhatt said that there are clinical scenarios in which GC therapy is the best choice, so just switching to nonsteroidal drugs is no panacea. “All RA drugs have adverse side effects, and anyway, the goal of rheumatology treatment is always to get patients off corticosteroids as soon as possible,” he said.

Ms. Costello and colleagues noted that their results are consonant with earlier research, including a single-center, cross-sectional study in which less than 6 months’ use of prednisolone at a median dose of 7.5 mg was associated with hypertension. In a German registry study, among patients who received doses of less than 7.5 mg for less than 6 months, there were higher rates of self-reported elevations in blood pressure.

The findings are at odds, however, with a recent matched-cohort study, which also used data from the Clinical Practice Research Datalink. That study found no association between GC use and hypertension.

GCs have come under increasing scrutiny in regard to several diseases. A study published July 7 found that even short-term courses of a few days’ duration entail risks for serious adverse events.

Ms. Costello’s group says that an estimate of GC-related incident hypertension in RA should allow more informed treatment decisions and that their findings highlight the ongoing need to monitor for and address this risk.

The study was supported by the Centre for Epidemiology Versus Arthritis and by the National Institute for Health Research Manchester Biomedical Research Centre. Coauthor William G. Dixon, PhD, has received consultancy fees from Google and Bayer unrelated to this study. Dr. Bhatt has disclosed no relevant financial relationships.

A single yearly dose of zoledronic acid had no impact on the progression of abdominal aortic calcification in postmenopausal women with osteoporosis, based on data from 502 women.

Although bisphosphonates have been shown to reduce the formation and progression of vascular calcification in animal studies, the impact on aortic calcification in humans has not been studied, wrote Guoqi Cai, PhD, of the University of Tasmania, Australia, and colleagues.

In a post hoc analysis published in Osteoporosis International, the researchers reviewed data from the HORIZON Pivotal Fracture trial of women with osteoporosis.

The study population included 234 postmenopausal women with osteoporosis who received an annual infusion of 5 mg zoledronic acid (ZA) and 268 who received a placebo. The mean age of the women was 72.5 years. Overall, abdominal aortic calcification (AAC) was present in 292 women (58%) at baseline, defined as an AAC score greater than 0, and AAC scores were similar between the intervention and placebo groups.

Over 3 years, AAC progressed similarly between the ZA and placebo groups (29% and 31%, respectively). Progression was defined as an increase in AAC score, which was measured by comparing spinal x-rays at baseline and after 3 years. In a subgroup analysis, progression of AAC was similar between the ZA and placebo groups with and without baseline AAC.

“The lack of effect on the progression of vascular calcification with zoledronic acid treatment in this study does not rule out a potential role of bisphosphonates in reducing cardiovascular mortality mediated through other mechanisms,” the researchers noted.

No correlation appeared between change in AAC score and change in bone mineral density at the total hip and femoral neck during the study period in any of the groups.

The study findings were limited by several factors including the post hoc analysis, potential lack of sensitivity of the AAC-8 scale in measuring small AAC changes, and homogenous study population, the researchers noted.

However, the study is the first to examine the impact of zoledronic acid on aortic calcification in humans, and was strengthened by the randomized design, the researchers said. Although other studies on the impact of bisphosphonates on vascular calcification have been inconsistent, the “finding that zoledronic acid was not protective against vascular calcification agrees with previous trials of nitrogen-containing bisphosphonates conducted in postmenopausal women with osteoporosis,” as well as chronic kidney disease patients and renal transplant patients, they said.

“Thus, our findings do not support the use of zoledronic acid for the treatment of vascular calcification,” they concluded.

A single yearly dose of zoledronic acid had no impact on the progression of abdominal aortic calcification in postmenopausal women with osteoporosis, based on data from 502 women.

Although bisphosphonates have been shown to reduce the formation and progression of vascular calcification in animal studies, the impact on aortic calcification in humans has not been studied, wrote Guoqi Cai, PhD, of the University of Tasmania, Australia, and colleagues.

In a post hoc analysis published in Osteoporosis International, the researchers reviewed data from the HORIZON Pivotal Fracture trial of women with osteoporosis.

The study population included 234 postmenopausal women with osteoporosis who received an annual infusion of 5 mg zoledronic acid (ZA) and 268 who received a placebo. The mean age of the women was 72.5 years. Overall, abdominal aortic calcification (AAC) was present in 292 women (58%) at baseline, defined as an AAC score greater than 0, and AAC scores were similar between the intervention and placebo groups.

Over 3 years, AAC progressed similarly between the ZA and placebo groups (29% and 31%, respectively). Progression was defined as an increase in AAC score, which was measured by comparing spinal x-rays at baseline and after 3 years. In a subgroup analysis, progression of AAC was similar between the ZA and placebo groups with and without baseline AAC.

“The lack of effect on the progression of vascular calcification with zoledronic acid treatment in this study does not rule out a potential role of bisphosphonates in reducing cardiovascular mortality mediated through other mechanisms,” the researchers noted.

No correlation appeared between change in AAC score and change in bone mineral density at the total hip and femoral neck during the study period in any of the groups.

Older adults, particularly postmenopausal women, are often advised to pursue low-impact, low-intensity exercise as a way to preserve joint health, but that approach might actually contribute to a decline in bone mineral density, researchers report.

Concerns about falls and fracture risk have led many clinicians to advise against higher-impact activities, like jumping, but that is exactly the type of activity that improves bone density and physical function, said Belinda Beck, PhD, professor at the Griffith University School of Allied Health Sciences in Southport, Australia.

“There has always been a quandary in terms of pursuing research on this,” she said in an interview. “We know from animal studies that bone only responds to high-intensity activity, but we worry about advising that for people with low bone mass, so instead we give them medications.”

“But not everyone likes to go on meds, they’re not 100% effective, and they’re not free of side effects,” said Beck, who is also the owner and director of The Bone Clinic in Brisbane, Australia.

In 2014, to assess whether high-intensity resistance and impact training (HiRIT) was a safe and effective way to improve bone mass, Beck and her colleagues conducted the LIFTMOR study of 101 postmenopausal women. The researchers showed that bone mineral density in the lumbar spine and femoral neck regions and functional performance measures were significantly better in the 49 participants randomized to HiRIT for 8 months than in the 52 randomized to low-intensity training.

Three years after the completion of LIFTMOR, the researchers looked at bone mineral density in 23 women from the HiRIT group in their retrospective observational study, the results of which were presented at the virtual American College of Sports Medicine 2020 Annual Meeting.

Ongoing gains were significantly better for the seven participants who continued with HiRIT (at least 25% compliance) than for the 16 who did not when looking at both bone mineral density of the lumbar spine (8.63% vs. 2.18%; P = .042) and femoral neck (3.67% vs. 2.85%; P = 0.14).

However, the women who discontinued HiRIT after 8 months maintained the gains in bone mineral density that they had achieved 3 years earlier.

Functional outcomes in the women who continued HiRIT were better than those in the women who did not, but the differences were not significant.

“The takeaway here is that this type of exercise appears to be a highly effective therapy to reduce risk of osteoporotic fracture, since it improves bone mass,” Beck said.

Jump more, lose less bone density

Given the widespread reluctance to suggest HiRIT-type activity to those with low bone mass, this research is significant, said Vanessa Yingling, PhD, from the Department of Kinesiology at California State University, East Bay.

“Once women hit 60, they’re somehow regarded as frail, but that becomes a self-fulfilling prophecy when we take this kinder, gentler approach to exercise,” Yingling said in an interview. “Building bone density in older adults is important, but maintaining current bone density is just as crucial. Without high-impact activity, we are likely to see decelerating density at a faster rate.”

The other key to the recent research is the functional testing, Yingling added. In addition to bone density measures, high-intensity activity can improve mobility and muscle strength, as the study noted.

This type of activity can be done in shorter bursts, making these workouts more efficient, she explained. For example, a Tabata high-intensity interval training session usually takes about 10 minutes, warm-up and cool-down included.

“A HiRIT workout even once or twice a week would likely improve function, strength, and bone density maintenance,” Beck said. “The result of that would be better fall prevention and potentially less medication usage for BMD issues.”

Both men and women can benefit from a HiRIT workout, Beck and Yingling said. Initially, supervision by a knowledgeable trainer or physical therapist is ideal, they added.

Dairy consumption does not improve bone mineral density (BMD) or reduce the risk of osteoporotic fracture in women starting menopause, a new analysis of the Study of Women’s Health Across the Nation (SWAN) indicates.

And this was regardless of baseline menopausal status, say Taylor Wallace, PhD, of George Mason University, Fairfax, Va., and colleagues in their article published online in Menopause.

“Our previous work indicated a potential premenopausal critical window in regard to the effectiveness of calcium supplements,” they noted.

Clifford Rosen, MD, professor of medicine, Tufts University, Boston, said in an interview that he believes the study reinforces earlier work that dairy intake in women aged 45-55 years does not affect the rate of bone loss or fractures.

“The SWAN study is longitudinal and with sufficient numbers to support their conclusion,” Dr. Rosen said.
 

SWAN study: White women consume the most dairy

As dairy is known to be one of the foremost sources of calcium, along with other bone beneficial nutrients, Dr. Wallace and colleagues decided to examine intake of this food type with long-term bone health using the SWAN data.

The SWAN bone substudy started in 1996 and involved 3,302 pre- or early perimenopausal women aged 42-53 years. The sample size for the annualized rate of BMD loss and fracture analysis involved 1955 women.

A modified food frequency questionnaire was used at baseline, at visit 5, and again at visit 9 to record daily dairy consumption, among many other food items.

“Women were classified into four dairy groups based on this cumulative average dairy intake,” Wallace and colleagues note. Intake was grouped into < 0.5 servings/day; 0.5 to < 1.5 servings/day; 1.5 to < 2.5 servings/day, and ≥ 2.5 servings/day.

“Non-Hispanic white individuals were more likely to consume higher amounts of dairy compared to African American, Chinese, and Japanese individuals,” the authors noted.

They found no significant differences for baseline age, body mass index, femoral neck and lumbar spine BMD, calcium supplement use, or fracture history by dairy intake group.

There were also no differences in the hazard ratios or relative risk of nontraumatic fractures by frequency of daily dairy intake.
 

Findings on dairy and bone are inconsistent

The authors caution that several factors should be taken into account when considering these new findings.

“First, dairy intake was low [overall] among SWAN participants, with 65% reporting consumption of < 1.5 servings/day,” they point out.

Dairy intake was also “particularly low” among racial groups other than whites, which may be due to higher rates of lactose intolerance among ethnic minorities, they speculate.

They previously reported that the use of calcium dietary supplements in SWAN was associated with a lower annualized rate of femoral neck BMD loss as well as BMD loss at the lumbar spine over 10 years of follow-up, mainly in women who were premenopausal at baseline.

But no associations were observed in the risk of bone fracture in any women in that analysis, regardless of menopausal status.

In this new analysis, there were no significant differences in calcium supplement use across the dairy intake groups.

Dr. Wallace and colleagues also noted that the relevance of dairy product intake for bone health has been in question as some observational studies have even “suggested consumption to be associated with an increased risk of fractures.”

The lead author of one of these studies, Karl Michaelsson, MD, PhD, of Uppsala (Sweden) University, said in an interview that his study had looked only at milk intake, and the lack of benefit on bone health from high milk consumption may not apply to all dairy products.

We “may need to look at different types of dairy products,” he said.

Summing up, Stephanie Faubion, MD, MBA, medical director of the North American Menopause Society, said the new SWAN findings do add to the evidence base, “albeit inconsistent ... suggesting a lack of benefit from dairy intake on BMD and fracture risk.”
 

Vitamin D data were not available; dairy may help in this respect

Dr. Rosen also noted that no information was available on vitamin D levels in patients involved in SWAN, which he believes is a limitation of the study.

Nevertheless, “it is important to recognize that elderly individuals who increase their dairy intake may have health benefits as recognized in the Nurses’ Health Study, possibly due to increased protein intake, higher vitamin D levels, or greater calcium intake,” he observed.

A randomized trial of enhanced dairy intake in long-term care residents is currently underway, which should provide answers for a much more vulnerable population than those in the SWAN cohort, Dr. Rosen concluded.

Dr. Wallace has reported serving on the scientific advisory board of the Vitamin Shoppe and has received research support from the National Dairy Council and scientific consulting fees from several food companies. Dr. Rosen has reported no relevant financial relationships.

In a national sample of U.S. women in their mid-40s to mid-50s, those with high serum levels of per- and polyfluoroalkyl substances (PFAS) were likely to enter menopause 2 years earlier than those with low levels of these chemicals.

That is, the median age of natural menopause was 52.8 years versus 50.8 years in women with high versus low serum levels of these chemicals in an analysis of data from more than 1,100 women in the Study of Women’s Health Across the Nation (SWAN) Multi-Pollutant Study, which excluded women with premature menopause (before age 40) or early menopause (before age 45).

“This study suggests that select PFAS serum concentrations are associated with earlier natural menopause, a risk factor for adverse health outcomes in later life,” Ning Ding, PhD, MPH, University of Michigan, Ann Arbor, and colleagues concluded in their article, published online June 3 in the Journal of Clinical Endocrinology & Metabolism.

“Even menopause a few years earlier than usual could have a significant impact on cardiovascular and bone health, quality of life, and overall health in general among women,” senior author Sung Kyun Park, ScD, MPH, from the same institution, added in a statement.

PFAS don’t break down in the body, build up with time

PFAS have been widely used in many consumer and industrial products such as nonstick cookware, stain-repellent carpets, waterproof rain gear, microwave popcorn bags, and firefighting foam, the authors explained.

These have been dubbed “forever chemicals” because they do not degrade. Household water for an estimated 110 million Americans (one in three) may be contaminated with these chemicals, according to an Endocrine Society press release.

“PFAS are everywhere. Once they enter the body, they don’t break down and [they] build up over time,” said Dr. Ding. “Because of their persistence in humans and potentially detrimental effects on ovarian function, it is important to raise awareness of this issue and reduce exposure to these chemicals.”

Environmental exposure and accelerated ovarian aging

Earlier menopause has been associated with an increased risk of cardiovascular disease, osteoporosis, and earlier cardiovascular and overall mortality, and environmental exposure may accelerate ovarian aging, the authors wrote.

PFAS, especially the most studied types – perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) – are plausible endocrine-disrupting chemicals, but findings so far have been inconsistent.

A study of people in Ohio exposed to contaminated water found that women with earlier natural menopause had higher serum PFOA and PFOS levels (J Clin Endocriniol Metab. 2011;96:1747-53).

But in research based on National Health and Nutrition Survey Examination data, higher PFOA, PFOS, or perfluorononanoic acid (PFNA) levels were not linked to earlier menopause, although higher levels of perfluorohexane sulfonic acid (PFHxS) were (Environ Health Perspect. 2014;122:145-50).

There may have been reverse causation, where postmenopausal women had higher PFAS levels because they were not excreting these chemicals in menstrual blood.

In a third study, PFOA exposure was not linked with age at menopause onset, but this was based on recall from 10 years earlier (Environ Res. 2016;146:323-30).

The current analysis examined data from 1,120 premenopausal women who were aged 45-56 years from 1999 to 2000.

The women were seen at five sites (Boston; Detroit; Los Angeles; Oakland, Calif.; and Pittsburgh) and were ethnically diverse (577 white, 235 black, 142 Chinese, and 166 Japanese).

Baseline serum PFAS levels were measured using high performance liquid chromatography-mass spectrometry. The women were followed up to 2017 and incident menopause (12 consecutive months with no menstruation) was determined from annual interviews.

Of the 1,120 women and 5,466 person-years of follow-up, 578 women had a known date of natural incident menopause and were included in the analysis. The remaining 542 women were excluded mainly because their date of final menstruation was unknown because of hormone therapy (451) or they had a hysterectomy, or did not enter menopause during the study.

Compared with women in the lowest tertile of PFOS levels, women in the highest tertile had a significant 26%-27% greater risk of incident menopause – after adjusting for age, body mass index, and prior hormone use, race/ethnicity, study site, education, physical activity, smoking status, and parity.

Higher PFOA and PFNA levels but not higher PFHxS levels were also associated with increased risk.

Compared with women with a low overall PFAS level, those with a high level had a 63% increased risk of incident menopause (hazard ratio, 1.63; 95% confidence interval, 1.08-2.45), equivalent to having menopause a median of 2 years earlier.

Although production and use of some types of PFAS in the United States are declining, Dr. Ding and colleagues wrote, exposure continues, along with associated potential hazards to human reproductive health.

“Due to PFAS widespread use and environmental persistence, their potential adverse effects remain a public health concern,” they concluded.

In a national sample of U.S. women in their mid-40s to mid-50s, those with high serum levels of per- and polyfluoroalkyl substances (PFAS) were likely to enter menopause 2 years earlier than those with low levels of these chemicals.

That is, the median age of natural menopause was 52.8 years versus 50.8 years in women with high versus low serum levels of these chemicals in an analysis of data from more than 1,100 women in the Study of Women’s Health Across the Nation (SWAN) Multi-Pollutant Study, which excluded women with premature menopause (before age 40) or early menopause (before age 45).

“This study suggests that select PFAS serum concentrations are associated with earlier natural menopause, a risk factor for adverse health outcomes in later life,” Ning Ding, PhD, MPH, University of Michigan, Ann Arbor, and colleagues concluded in their article, published online June 3 in the Journal of Clinical Endocrinology & Metabolism.

“Even menopause a few years earlier than usual could have a significant impact on cardiovascular and bone health, quality of life, and overall health in general among women,” senior author Sung Kyun Park, ScD, MPH, from the same institution, added in a statement.

PFAS don’t break down in the body, build up with time

PFAS have been widely used in many consumer and industrial products such as nonstick cookware, stain-repellent carpets, waterproof rain gear, microwave popcorn bags, and firefighting foam, the authors explained.

These have been dubbed “forever chemicals” because they do not degrade. Household water for an estimated 110 million Americans (one in three) may be contaminated with these chemicals, according to an Endocrine Society press release.

“PFAS are everywhere. Once they enter the body, they don’t break down and [they] build up over time,” said Dr. Ding. “Because of their persistence in humans and potentially detrimental effects on ovarian function, it is important to raise awareness of this issue and reduce exposure to these chemicals.”

The direct oral anticoagulant (DOAC) drugs apixaban, dabigatran, and rivaroxaban are associated with a lower risk of osteoporotic fracture than is warfarin in patients with atrial fibrillation (AFib), according to a new retrospective analysis.

There was no difference in risk between individual DOAC medications.

The study drew from an EHR database of the Hong Kong Hospital Authority. It was led by Wallis C.Y. Lau, PhD, of the University of Hong Kong and appeared online May 19 in Annals of Internal Medicine.

Warfarin is suspected to contribute to osteoporotic fracturing in AFib patients, but previous studies returned mixed results. The more recently introduced DOACs were not tested for fracture risks, and it hasn’t been determined if individual DOACs have different risks. The question is even more important in AFib, in which patients are older and often have comorbidities that could predispose them to fractures.

The study included 23,515 patients with AFib who used anticoagulants. 3,241 used apixaban, 6,867 dabigatran, 3,866 rivaroxaban, and 9,541 used warfarin. The median follow-up was 423 days.

According to Cox proportional hazards model analyses, DOAC use was associated with fewer fractures than was warfarin (hazard ratio for apixaban vs. warfarin, 0.62; 95% confidence interval, 0.41-0.94; HR for dabigatran, 0.65; 95% CI, 0.49-0.86; HR for rivaroxaban, 0.52; 95% CI, 0.37-0.73). Subanalyses in men and women showed similar results (P for interaction >.05).

Head-to-head comparisons between individual DOACs yielded no statistically significant differences in osteoporotic fracture risk.

Although the findings couldn’t absolutely rule out a difference in osteoporotic fracture risk between different DOACs, the authors argue that any clinical significance would likely be small.

“Given the supportive evidence from experimental settings, findings from our study using clinical data, and the indirect evidence provided by the previous meta-analysis of randomized, controlled trials, there exists a compelling case for evaluating whether the risk for osteoporotic fractures should be considered at the point of prescribing an oral anticoagulant to minimize fracture risk,” the authors wrote.

The study is limited by the potential for residual confounding, the investigators noted.

The study was funded by the University of Hong Kong and University College London Strategic Partnership Fund.

Among patients with atrial fibrillation, use of direct oral anticoagulants is linked to lower osteoporotic fracture risk versus warfarin, results of a recent population-based cohort study show.

The choice of direct oral anticoagulant (DOAC) didn’t appear to have an impact, as each individual agent yielded a substantially lower risk of fracture versus the vitamin K antagonist, with risk reductions ranging from 38% to 48%, according to the study authors.

This is one of the latest reports to suggest DOACs could have an edge over warfarin for preventing fractures, providing new evidence that “may help inform the benefit risk assessment” when it comes to choosing an anticoagulant for a patient with atrial fibrillation (AFib) in the clinic, wrote the authors, led by Wallis C.Y. Lau, PhD, with the University College London.

“There exists a compelling case for evaluating whether the risk for osteoporotic fractures should be considered at the point of prescribing an oral anticoagulant to minimize fracture risk,” Dr. Lau and coauthors wrote in a report on the study that appears in Annals of Internal Medicine.

The case is especially compelling since fracture risk is “often neglected” when choosing an anticoagulant, the authors wrote. Surgeries to treat fracture are difficult because of the need for perioperative management of anticoagulation as “a balance between the risk for stroke and excessive bleeding must be achieved,” they added.

Based on these data, physicians should strongly consider DOACs as an alternative to vitamin K antagonists to reduce the risk of osteoporosis over the long term in patients with AFib, according to Victor Lawrence Roberts, MD, a Florida endocrinologist.

“Osteoporosis takes years, sometimes decades to develop, and if you then overlay warfarin on top of a readily evolving metabolic bone disease, you probably accelerate that process, said Dr. Roberts, professor of internal medicine at the University of Central Florida, Orlando, and editorial advisory board member of Internal Medicine News.

There’s a considerable amount of concerning preclinical data that warfarin could increase osteoporotic fracture risk. Of note, vitamin K antagonists modulate osteocalcin, a calcium-binding bone matrix protein, Dr. Roberts said.

“Osteocalcin is important for bone metabolism and health, and inhibiting osteocalcin will inhibit the ability to have a healthy bone matrix,” he explained.

The impact of anticoagulants on fracture risk is particularly relevant to patients with AFib, according to Dr. Lau and colleagues, who referenced one 2017 report showing a higher incidence of hip fracture among AFib patients versus those without AFib.

In their more recent study, Dr. Lau and colleagues reviewed electronic health records in a Hong Kong database for 23,515 older adults with a new diagnosis of AFib who received a new prescription of warfarin or DOACs including apixaban, dabigatran, or rivaroxaban.

DOAC use was consistently associated with a lower risk of osteoporotic fractures versus warfarin, regardless of the DOAC considered. The hazard ratios were 0.62 (95% confidence interval, 0.41-0.94) for apixaban, 0.65 (95% CI, 0.49-0.86) for dabigatran, and 0.52 (95% CI, 0.37-0.73) for rivaroxaban versus warfarin, the report showed.

Head-to-head comparisons between DOACS didn’t yield any statistically significant differences, though the analyses were underpowered in this respect, according to the investigators.

“This study can only rule out more than a twofold higher or a 50% lower relative risk for osteoporotic fractures between individual DOACs,” they wrote. “However, any absolute risk differences were small and would likely be of minor clinical significance.”

The reduced risk of fracture for DOACs versus warfarin was consistent in men and women with AFib, suggesting that women may particularly benefit from DOACs, given that they have a higher risk of fracture than men, the investigators added.

The results of this study suggest yet another benefit of DOACs over warfarin in patients with AFib, according to internist Noel Deep, MD, who is the chief medical officer of Aspirus Langlade Hospital in Antigo, Wisconsin.

“The lower risk of osteoporotic fractures with DOACS, in addition to other advantages such as lower risk of intracranial bleeding, once- or twice-daily consistent dosing, no dietary restrictions, and no blood tests to regulate the dose might be another reason that physicians may favor them over warfarin in older individuals requiring anticoagulation,” Dr. Deep said in an interview.

Results of this and several other recent studies may help in recommending DOACs to internal medicine patients who have a diagnosis of AFib requiring anticoagulation, according to Dr. Deep, who is also a physician at Aspirus Antigo Clinic and a member of Internal Medicine News’ editorial advisory board. These include a 2019 U.S.-based study of more than 167,000 patients with AFib (JAMA Intern Med. 2019;180[2]:245‐253) showing that use of DOACs, particularly apixaban, were linked to lower fracture risk versus warfarin use. Similarly, a Danish national registry study also published in 2019 showed that the absolute risk of osteoporotic fractures was low overall and significantly lower in patients who received DOACs (J Am Coll Cardiol. 2019;74[17]:2150-2158).

Funding for the study came from the University of Hong Kong and University College London Strategic Planning Fund. The study authors reported disclosures related to Bayer, Bristol-Myers Squibb, Pfizer, Janssen, Amgen, Takeda, IQVIA, and others.

Among patients with atrial fibrillation, use of direct oral anticoagulants is linked to lower osteoporotic fracture risk versus warfarin, results of a recent population-based cohort study show.

The choice of direct oral anticoagulant (DOAC) didn’t appear to have an impact, as each individual agent yielded a substantially lower risk of fracture versus the vitamin K antagonist, with risk reductions ranging from 38% to 48%, according to the study authors.

This is one of the latest reports to suggest DOACs could have an edge over warfarin for preventing fractures, providing new evidence that “may help inform the benefit risk assessment” when it comes to choosing an anticoagulant for a patient with atrial fibrillation (AFib) in the clinic, wrote the authors, led by Wallis C.Y. Lau, PhD, with the University College London.

“There exists a compelling case for evaluating whether the risk for osteoporotic fractures should be considered at the point of prescribing an oral anticoagulant to minimize fracture risk,” Dr. Lau and coauthors wrote in a report on the study that appears in Annals of Internal Medicine.

The case is especially compelling since fracture risk is “often neglected” when choosing an anticoagulant, the authors wrote. Surgeries to treat fracture are difficult because of the need for perioperative management of anticoagulation as “a balance between the risk for stroke and excessive bleeding must be achieved,” they added.

Based on these data, physicians should strongly consider DOACs as an alternative to vitamin K antagonists to reduce the risk of osteoporosis over the long term in patients with AFib, according to Victor Lawrence Roberts, MD, a Florida endocrinologist.

“Osteoporosis takes years, sometimes decades to develop, and if you then overlay warfarin on top of a readily evolving metabolic bone disease, you probably accelerate that process, said Dr. Roberts, professor of internal medicine at the University of Central Florida, Orlando, and editorial advisory board member of Internal Medicine News.

There’s a considerable amount of concerning preclinical data that warfarin could increase osteoporotic fracture risk. Of note, vitamin K antagonists modulate osteocalcin, a calcium-binding bone matrix protein, Dr. Roberts said.

“Osteocalcin is important for bone metabolism and health, and inhibiting osteocalcin will inhibit the ability to have a healthy bone matrix,” he explained.

The impact of anticoagulants on fracture risk is particularly relevant to patients with AFib, according to Dr. Lau and colleagues, who referenced one 2017 report showing a higher incidence of hip fracture among AFib patients versus those without AFib.

In their more recent study, Dr. Lau and colleagues reviewed electronic health records in a Hong Kong database for 23,515 older adults with a new diagnosis of AFib who received a new prescription of warfarin or DOACs including apixaban, dabigatran, or rivaroxaban.

DOAC use was consistently associated with a lower risk of osteoporotic fractures versus warfarin, regardless of the DOAC considered. The hazard ratios were 0.62 (95% confidence interval, 0.41-0.94) for apixaban, 0.65 (95% CI, 0.49-0.86) for dabigatran, and 0.52 (95% CI, 0.37-0.73) for rivaroxaban versus warfarin, the report showed.

Head-to-head comparisons between DOACS didn’t yield any statistically significant differences, though the analyses were underpowered in this respect, according to the investigators.

“This study can only rule out more than a twofold higher or a 50% lower relative risk for osteoporotic fractures between individual DOACs,” they wrote. “However, any absolute risk differences were small and would likely be of minor clinical significance.”

The reduced risk of fracture for DOACs versus warfarin was consistent in men and women with AFib, suggesting that women may particularly benefit from DOACs, given that they have a higher risk of fracture than men, the investigators added.

The results of this study suggest yet another benefit of DOACs over warfarin in patients with AFib, according to internist Noel Deep, MD, who is the chief medical officer of Aspirus Langlade Hospital in Antigo, Wisconsin.

“The lower risk of osteoporotic fractures with DOACS, in addition to other advantages such as lower risk of intracranial bleeding, once- or twice-daily consistent dosing, no dietary restrictions, and no blood tests to regulate the dose might be another reason that physicians may favor them over warfarin in older individuals requiring anticoagulation,” Dr. Deep said in an interview.

Results of this and several other recent studies may help in recommending DOACs to internal medicine patients who have a diagnosis of AFib requiring anticoagulation, according to Dr. Deep, who is also a physician at Aspirus Antigo Clinic and a member of Internal Medicine News’ editorial advisory board. These include a 2019 U.S.-based study of more than 167,000 patients with AFib (JAMA Intern Med. 2019;180[2]:245‐253) showing that use of DOACs, particularly apixaban, were linked to lower fracture risk versus warfarin use. Similarly, a Danish national registry study also published in 2019 showed that the absolute risk of osteoporotic fractures was low overall and significantly lower in patients who received DOACs (J Am Coll Cardiol. 2019;74[17]:2150-2158).
