VANCOUVER – The use of tricyclic antidepressants (TCAs) conferred the highest risk for a new, first-time clinical fracture in people with type 2 diabetes with overweight or obesity, independent of any prevalent neuropathy, according to findings from an analysis of a large, randomized clinical trial.

Although the findings are suggestive, they don’t definitively pin blame on TCAs, said Rachel Elam, MD, who presented the study at the annual meeting of the American Society for Bone and Mineral Research. “I think that there’s not enough information to conclude that tricyclic antidepressants directly lead to fractures, but I think it opens the door [to] something we should look into more. Is it being mediated by a better predictor, or is it the medication itself? I think it’s more hypothesis generating,” said Dr. Elam, an assistant professor of medicine in the division of rheumatology at the Medical College of Georgia, Augusta.

Patients with type 2 diabetes are known to be at increased risk of fracture, but prediction tools tend to underestimate this risk, Dr. Elam said. “Type 2 diabetes–specific clinical risk factors may be helpful for finding out fracture risk in this population,” Dr. Elam said during her talk.

Glycemic control is one candidate risk factor because advanced glycation end products are linked to reduced bone strength. Other factors include antidiabetic medication use, neuropathy, and microvascular disease, which has been linked to increased cortical porosity.

The study examined a somewhat younger population than previous surveys, having drawn from the Look AHEAD-C clinical trial, which examined the effects of an intensive lifestyle intervention on type 2 diabetes. Look AHEAD-C included 4,697 participants aged 45-75 from 16 U.S. clinical sites. Participants had a body mass index of 25.0 kg/m² or higher and hemoglobin A1c levels of 11% or below.

Dr. Elam cited the database’s inclusion of factors like A1c levels, renal parameters, and diabetic neuropathy. “It gave us a really good population to look at those risk factors” in a large group of people with type 2 diabetes, she said.

Over a median follow-up of 16.6 years, there were 649 participants with incident first clinical fracture(s). Statistically significant factors predicting fracture risk included TCA use (hazard ratio, 2.24; 95% confidence interval, 1.14-4.43), female gender (HR, 2.20; 95% CI, 1.83-2.66), insulin use (HR, 1.26; 95% CI, 1.02-1.57), increases in A1c level (per 1% increase: HR, 1.12; 95% CI, 1.04-1.20), age (HR, 1.02; 95% CI, 1.01-1.04), other or mixed race/ethnicity (HR, 0.68; 95% CI, 0.52-0.87), Hispanic White race/ethnicity (HR, 0.60; 95% CI, 0.39-0.91), non-Hispanic Black race/ethnicity (HR, 0.35; 95% CI, 0.26-0.47), and estrogen use (HR, 0.65; 95% CI, 0.44-0.98).

During the Q&A session following the presentation, Elsa Strotmeyer, PhD, commented that TCAs have been linked to central nervous system pathways in falls in other populations. “It’s a very nice study. It’s important to look at the diabetes complications related to the fracture risk, but I thought that they should have emphasized some more of the diabetes complications being related to fracture rather than these tricyclic antidepressants, because that is not a unique factor to that population,” said Dr. Strotmeyer, who is an associate professor of epidemiology at the University of Pittsburgh.

Instead, she noted a different strength of the study. “The study population is important because they’re a relatively young population with type 2 diabetes, compared to many studies [that] have been published in older populations. Showing similar things that we found in older populations was the unique piece and the important piece of this study,” Dr. Strotmeyer said.

Ultimately, the model wasn’t sufficient to be used as a fall risk predictor, but it should inform future work, according to Dr. Elam. “I think it does lay some new groundwork that when we’re looking forward, it may [help in building] other models to better predict fracture risk in type 2 diabetes. Things that would be important to include [in future models] would be medication use, such as tricyclic antidepressants,” and to make sure we include glycemic control, A1c, and insulin medication.

The study was independently funded. Dr. Elam and Dr. Strotmeyer report no relevant financial relationships.

WASHINGTON – In psoriatic disease, psoriatic arthritis (PsA) remains one of the greatest unmet needs, with the transition from cutaneous psoriasis poorly understood, diagnosis challenging, and therapeutic accomplishments trailing far behind advances for skin disease. However, leading researchers in rheumatology and dermatology believe that they’re turning the corner toward a day when therapies are phenotype-targeted and diagnosis can be made early and treatment begun well before inflammation worsens and pain and joint damage ensue.

“The challenge right now is that we don’t understand the discrete and overlapping endotypes that underlie the phenotypes or domains” of PsA, said Christopher Ritchlin, MD, MPH, professor of medicine in the division of allergy/immunology and rheumatology and the Center of Musculoskeletal Research at the University of Rochester (N.Y.), who spoke about PsA at the annual research symposium of the National Psoriasis Foundation.

A deep dive into the tissue

Dr. Ritchlin is among those rheumatology clinician-researchers who advocated early on for a “domain” approach to the diagnosis and management of PsA – that is, consideration of the key domains of peripheral arthritis, axial disease, enthesitis, dactylitis, and skin and nail psoriasis.

The approach is an especially important part of treatment recommendations from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis. But while interventions can be tailored to some extent to these domains, or phenotypes, there are limitations without an understanding of the different pathophysiology and mechanisms driving the heterogeneity in tissue involvement.

Dr. Ritchlin draws inspiration from pulmonology, which subtyped asthma into various phenotypes (for example, eosinophilic, allergic, intrinsic, exercise-induced) and “drilled down” on understanding underlying mechanisms to guide more specific treatment. Similar phenotype-endotype research has been done for chronic obstructive pulmonary disease, he said at the meeting, pointing to a phase 3 randomized controlled trial, published in the New England Journal of Medicine, that found dupilimab (Dupixent) was effective for patients with COPD who had type 2 inflammation as indicated by elevated eosinophil counts.

“It’s a beautiful example of how to define an endotype from a phenotypic biomarker and then use a specific intervention to improve outcomes,” Dr. Ritchlin said. “We need to do this for psoriasis and PsA.”

The ELLIPSS project will utilize the host of -omics tools and technologies (for proteomics, metabolomics, and genomics, for instance) that are making it increasingly possible to dissect the heterogeneity of single diseases and achieve more precision with treatments.

Researchers will collect blood samples and skin and/or synovial tissue biopsies from cohorts of patients with psoriasis and PsA who are treatment naïve as well as patients who are treated with a biologic or DMARD (looking at responders and non-responders). They’ll also study a cohort of psoriasis patients who may be “on a transition pathway” for PsA based on risk factors such as family history, nail psoriasis, scalp psoriasis, and body surface area greater than 5%.

Patients in all cohorts will represent distinct synovio-entheseal domains of PsA and the heterogeneity of psoriasis (for example, plaque, general, pustular, palmoplantar) and will be followed longitudinally.

With regards to PsA, one goal is to “find new pathways in the joint, then find surrogate markers in the blood that we can use to help mark particular subphenotypes [that will be identified through deep phenotyping],” Dr. Ritchlin said in an interview after the meeting. “This will lead us hopefully to a more precision-based approach.”

The ELLIPSS team joins other researchers who have been studying rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) in an earlier iteration of the AIM program, and that will continue this work. Research on RA has thus far elucidated T-cell subsets in the rheumatoid synovium, as well as interactions of mesenchymal cells with the endothelium, for instance, and led to the identification of key molecules such as granzyme A that weren’t previously known to be involved in RA pathogenesis, Dr. Ritchin said in the interview. The current AIM work also includes Sjögren’s disease.
 

Finding biomarkers, diagnostic signatures

The psoriasis-PsA team has the advantage today of being able to utilize a new technology called spatial transcriptomics, which takes transcriptomics (RNA) from the single-cell level to the tissue level, enabling a look at how disease is affecting cellular organization/tissue architecture, gene activity, and cellular signaling within tissues. “It’s a huge advance in technology,” said Dr. Ritchlin. “We can actually see how the cells are interacting in the synovium [and other tissues].”

A paper published in Science Immunology and discussed at the NPF meeting demonstrates the power of special transcriptomics for learning about the skin. Dr. Scher, Dr. Ritchlin, first authors Rochelle L. Castillo, MD, and Ikjot Sidhu, MS, and other co-investigators reported a “dynamic re-organization of the immune milieu and fibroblasts in PsO lesional and non-lesional skin,” the presence of B cells in lesioned skin, and cellular organization/ecosystems that vary occurring according to clinical severity, among other findings.

Dr. Scher is using the tool for his NPF-funded diagnostic test research and as part of his work at NYU Langone for the ELLIPPS project. Among his goals: To “discover new cell populations in the microenvironment and study how they interact with each other, then compare those cells between psoriasis and PsA patients to first understand if they’re any different,” he explained after the meeting. Researchers can then investigate the synovial tissue, comparing cell populations and interactions in both compartments and looking for any shared markers/cytokines/proteins, he said.

Multiomics research, meanwhile, is showing that a test for early PsA detection could potentially combine clinical parameters with integrated multi-omic markers into a “diagnostic signature” of sorts.

At the meeting, Vinod Chandran, MD, PhD, a rheumatologist at the University of Toronto who also has an NPF PsA diagnostic test grant, said that his multi-omics analysis of blood samples from patients with psoriasis and PsA has identified signatures with a “high discriminatory value” and that certain metabolic pathways appear to play “a central role in the development and differentiation of PsA.” (Validation in other cohorts and economic analyses are ongoing, Dr. Chandran said. Low-cost alternatives that can be applied broadly in the clinic will need to be pursued, Dr. Scher said.)

Eyes on combination therapy

“The likelihood that all patients will respond to one biologic is very low in PsA, so we’ve been thinking about combination therapy for some time,” Dr. Ritchlin said at the meeting. “I think [dual inhibition] is coming.”

Safety has been the concern, but a phase 2 trial published this year compared a combination of IL-23 and TNF inhibition (guselkumab [Tremfya] plus golimumab [Simponi]) with monotherapy of both biologics in patients with ulcerative colitis and showed that the combination safely drove synergistic restoration of a normal epithelium and mucosal healing, he said.

A phase 2 trial in PsA, designed by Dr. Ritchlin and Dr. Scher and named AFFINITY, will study the safety and efficacy of the same combination of IL-23 and TNF blockade, compared with guselkumab (IL-23 inhibition) alone. The trial is currently completing enrollment of patients who have failed one or two anti-TNF agents.

In the meantime, combination therapy is being employed in clinics for “PsA patients who’ve been channeled through multiple biologics and are still not responding ... when [physicians] feel they’re forced to, not right away,” Dr. Ritchlin said in an interview after the meeting. “As we get a better understanding [through clinical trials], it might be something you’ll see earlier in the treatment process.”

It is wise, Dr. Ritchlin said, to devote more time to addressing “extra-articular traits” (for example, obesity, diabetes, uveitis, colitis, centralized pain) and treatable lifestyle/behavioral risk factors (for example, smoking, exercise, nutrition, adherence to therapy, social support) that can contribute to PsA and treatment nonresponse. He calls this the “treatable traits” strategy.

In practice, “there’s a big focus on inflammation and immune dysfunction, but the problem is, there are other factors involved in nonresponse, and I think ‘treatable traits’ gets to those,” Dr. Ritchlin said after the meeting. Rheumatologists and dermatologists lack time and alliances to address these issues, but “if we can find ways to do it, I think we’ll have improved outcomes.”

Dr. Ritchlin, Dr. Chandran, and Dr. Liao reported no relevant disclosures. Dr. Scher reported ties to Janssen, Pfizer, Sanofi, UCB, and Bristol-Myers Squibb.

Research on RA has thus far elucidated T-cell subsets in the rheumatoid synovium, as well as interactions of mesenchymal cells with the endothelium, for instance, and led to the identification of key molecules such as granzyme A that weren’t previously known to be involved in RA pathogenesis, Dr. Ritchin said in the interview. The current AIM work also includes Sjögren’s disease.
 

Finding biomarkers, diagnostic signatures

The psoriasis-PsA team has the advantage today of being able to utilize a new technology called spatial transcriptomics, which takes transcriptomics (RNA) from the single-cell level to the tissue level, enabling a look at how disease is affecting cellular organization/tissue architecture, gene activity, and cellular signaling within tissues. “It’s a huge advance in technology,” said Dr. Ritchlin. “We can actually see how the cells are interacting in the synovium [and other tissues].”

A paper published in Science Immunology and discussed at the NPF meeting demonstrates the power of special transcriptomics for learning about the skin. Dr. Scher, Dr. Ritchlin, first authors Rochelle L. Castillo, MD, and Ikjot Sidhu, MS, and other co-investigators reported a “dynamic re-organization of the immune milieu and fibroblasts in PsO lesional and non-lesional skin,” the presence of B cells in lesioned skin, and cellular organization/ecosystems that vary occurring according to clinical severity, among other findings.

Dr. Scher is using the tool for his NPF-funded diagnostic test research and as part of his work at NYU Langone for the ELLIPPS project. Among his goals: To “discover new cell populations in the microenvironment and study how they interact with each other, then compare those cells between psoriasis and PsA patients to first understand if they’re any different,” he explained after the meeting. Researchers can then investigate the synovial tissue, comparing cell populations and interactions in both compartments and looking for any shared markers/cytokines/proteins, he said.

Multiomics research, meanwhile, is showing that a test for early PsA detection could potentially combine clinical parameters with integrated multi-omic markers into a “diagnostic signature” of sorts.

At the meeting, Vinod Chandran, MD, PhD, a rheumatologist at the University of Toronto who also has an NPF PsA diagnostic test grant, said that his multi-omics analysis of blood samples from patients with psoriasis and PsA has identified signatures with a “high discriminatory value” and that certain metabolic pathways appear to play “a central role in the development and differentiation of PsA.” (Validation in other cohorts and economic analyses are ongoing, Dr. Chandran said. Low-cost alternatives that can be applied broadly in the clinic will need to be pursued, Dr. Scher said.)

Eyes on combination therapy

“The likelihood that all patients will respond to one biologic is very low in PsA, so we’ve been thinking about combination therapy for some time,” Dr. Ritchlin said at the meeting. “I think [dual inhibition] is coming.”

Safety has been the concern, but a phase 2 trial published this year compared a combination of IL-23 and TNF inhibition (guselkumab [Tremfya] plus golimumab [Simponi]) with monotherapy of both biologics in patients with ulcerative colitis and showed that the combination safely drove synergistic restoration of a normal epithelium and mucosal healing, he said.

A phase 2 trial in PsA, designed by Dr. Ritchlin and Dr. Scher and named AFFINITY, will study the safety and efficacy of the same combination of IL-23 and TNF blockade, compared with guselkumab (IL-23 inhibition) alone. The trial is currently completing enrollment of patients who have failed one or two anti-TNF agents.

In the meantime, combination therapy is being employed in clinics for “PsA patients who’ve been channeled through multiple biologics and are still not responding ... when [physicians] feel they’re forced to, not right away,” Dr. Ritchlin said in an interview after the meeting. “As we get a better understanding [through clinical trials], it might be something you’ll see earlier in the treatment process.”

It is wise, Dr. Ritchlin said, to devote more time to addressing “extra-articular traits” (for example, obesity, diabetes, uveitis, colitis, centralized pain) and treatable lifestyle/behavioral risk factors (for example, smoking, exercise, nutrition, adherence to therapy, social support) that can contribute to PsA and treatment nonresponse. He calls this the “treatable traits” strategy.

In practice, “there’s a big focus on inflammation and immune dysfunction, but the problem is, there are other factors involved in nonresponse, and I think ‘treatable traits’ gets to those,” Dr. Ritchlin said after the meeting. Rheumatologists and dermatologists lack time and alliances to address these issues, but “if we can find ways to do it, I think we’ll have improved outcomes.”

Dr. Ritchlin, Dr. Chandran, and Dr. Liao reported no relevant disclosures. Dr. Scher reported ties to Janssen, Pfizer, Sanofi, UCB, and Bristol-Myers Squibb.

Alexandra Kharazi, MD, a California-based cardiothoracic surgeon, previously worked as an employed physician and is now in private practice. Though she appreciates that there are some trade-offs to working with her small group of three surgeons, Dr. Kharazi has no qualms about her choice.

“For me, it’s an issue of autonomy,” she said. “While I have to work a lot of hours, I don’t have to adhere to a strict schedule. I also don’t have to follow specific policies and rules.”

In contrast, Cassandra Boduch, MD, an employed psychiatrist with PsychPlus in Houston, is very satisfied with working as an employee. “I looked into private practice, but no one really prepares you for the complications that come with it,” she said. “There’s a lot more that goes into it than people realize.”

By hanging up her own shingle, Dr. Kharazi may be living a rapidly shrinking dream. According to the American Medical Association, between 2012 and 2022, the share of physicians working in private practice fell from 60% to 47%. The share of physicians working in hospitals as direct employees or contractors increased from about 6% to about 10% during the same time period.

Many factors contribute to these shifting trends, a major factor being economic stress stemming from payment cuts in Medicare. Add in rising practice costs and administrative burdens, and more doctors than ever are seeking employment, according to the AMA.

Though the traditional dream of owning your own practice may be slipping away, are employed physicians less happy than are their self-employed peers? By many measures, the answer is no.

In Medscape’s Employed Physicians Report 2023, doctors weighed in on the pros and cons of their jobs.

When asked what they like most about their jobs, employed physician respondents reported “not having to run a business” as their number-one benefit, followed closely by a stable income. The fact that employers pay for malpractice insurance ranked third, followed by work-life balance.

“We get no business classes in medical school or residency,” said one employed physician. “Having a good salary feels good,” said another. Yet another respondent chimed in: “Running a practice as a small business has become undoable over the past 10-12 years.”

And 50% of employed physicians said that they were “very satisfied/satisfied” with their degree of autonomy.

Still, employed physicians also had plenty to say about the downsides of their jobs.

Many pointed to “feeling like a cog in the machine,” and one doctor pointed to the hassle of dealing with bureaucracy. Others complained about the fact that nonphysicians ran the business and lacked an understanding of what physicians really need from their jobs. When asked whether administrative rules made sense, 63% of physician respondents said that yes, the rules make sense for the business; but, only 52% said that the rules make sense for the doctors themselves.

Other complaints included the requirement to reach high productivity targets and too low an income potential. In the 9 years since Medscape’s 2104 Employed Physicians Report, the share of employed doctors paid on a straight salary has declined from 46% to 31%. Those compensated on a base salary plus productivity targets and other performance metrics rose from 13% in 2014 to 32% now.

“Many doctors go into private practice because of the freedom it brings and the potential financial incentives,” added Dr. Boduch. “I know that many doctors have a dream of working for themselves, and in many cases, that works out great for them.”

Dr. Boduch noted that in her job as chief medical officer at PsychPlus, she still has flexibility plus the perks of working with a bigger practice. In this scenario, Dr. Boduch said, the company can negotiate with insurance companies, allowing her the financial rewards of private practice.
 

What’s right for you?

“I think it might be somewhat generational,” said Cody Futch, senior recruiting executive at AMN Healthcare. “It used to be that fewer hospitals offered employment, so private practice was the way to go. Now, there are fewer privates because hospitals and corporations are buying them up.”

This reality has potentially shaped the way younger generations approach their workplace. Also, Gen Z tends to have less intention to stay with a current employer for the long term than did their parents. “Older physicians were trained to expect they’d run their own business and build it over the years,” said Mr. Futch. “The younger generations look at it as a job, something they may want to switch in a few years. It’s a combination of candidates wanting more options, and also the fact that there are more options to be employed.”

Along those lines, younger generations in general tend to place work-life balance as a higher priority than do older generations, and employed physicians place this equation high on the list as well. In the Employed Physicians Report 2023, 54% said that they are satisfied or better with their work-life balance, up from 51% in the 2022 report.

With that in mind, Dr. Kharazi noted that flexibility is one of the chief reasons why she likes private practice. “If my kid has an event I want to attend, I don’t have to adhere to a strict schedule,” she said.

Satisfaction as an employee vs. employed doctor sometimes changes based on the type of medicine you practice too. With specialties that tend to be primarily outpatient, such as dermatology and allergy, private practice may be the best option regardless. “Hospitals don’t seek out those specialists as much and the specialists can operate successfully without a hospital,” said Mr. Futch.

Hospitals try to incentivize doctors with perks like hefty sign-on bonuses, student loan forgiveness, plenty of vacation time, and more. They also put money into marketing their doctors, a time-consuming and expensive aspect that is tough to shoulder in private practice, especially in the early years. Mr. Futch adds that many doctors view employment as a more stable option. “As the government changes reimbursement policies, the income from private practice fluctuates,” he said. “So many doctors worry that if they buy into a private practice, it is a risky endeavor.”

Hospitals aren’t always a sure bet in that regard, either: They go through tough financial times, lay off staff, or make salary cuts. Historically, however, employment tends to be the safer route, which can make it an attractive option.

Ultimately, the pros and cons of each scenario are individual. It’s up to physicians to do their own math and balance sheet before making a decision.

VANCOUVER – A new calculator that predicts short-term fracture risk at both 1 year and 3 years in patients on dialysis performed well in a study presented at the annual meeting of the American Society for Bone and Mineral Research.

The tool will soon be available on QxMD Calculate, which provides free decision-support tools for physicians, said presenter Andrea Cowan, MD, an assistant professor of medicine at the University of Western Ontario, London.

Dialysis patients have an approximately fivefold increased risk for fracture, Dr. Cowan noted, compared with the general population. However, treatments to prevent fracture risk are relatively limited and can have significant side effects. Therefore, “you really want to make sure that the person you’re targeting for treatment is actually going to be at a reasonable risk of fracture,” she said.

The Fracture Risk Assessment Tool (FRAX) is useful, but it estimates 10-year fracture risk, which is too long of a time frame to be useful for dialysis patients who experience a 50% 5-year mortality, according to Dr. Cowan. It does not take kidney failure or severe hyperparathyroidism into account, and it also requires information like bone mineral density, which poses an additional burden for a dialysis patient already undergoing multiple tests.

The new calculator could also be useful for research because it doesn’t rely on clinical data that might not be generally available, such as parental fracture, smoking status, or body mass index. “There’s a move towards things like pragmatic trials, which use more routinely collected data, have broader inclusion criteria, and are often more cost efficient to run. This calculator should be relatively easy to implement in trials using routinely collected data to perhaps define a subgroup of patients who may be at high risk of fracture without having to apply really cumbersome tools,” Dr. Cowan said.

The researchers included 11,599 patients between ages 40 and 89 years who were treated at a single center in Ontario between 2010 and 2017. The mean age was 66.18 years, 38.6% were women, 64.1% had diabetes, 11.9% had liver disease, and median time on dialysis was 0.81 years. The patients’ median parathyroid hormone level was 30 pmol/L.

At 3 years, the cumulative incidence of any fracture was 7.36% (95% confidence interval, 6.89-7.85), including 2.62% for hip fracture (95% CI, 2.34-2.93), 1.36% for spine fracture (95% CI, 1.16-1.59), 1.93% for wrist or forearm (95% CI, 1.69-2.20), and 2.15% for the pelvis (95% CI, 1.89-2.43). The incidence for all fractures at 1 year was 2.93 (95% CI, 2.62-3.26).

Variables associated with fracture risk included female sex (hazard ratio, 1.46; 95% CI, 1.27-1.67), a previous fracture more than 1 year in the past (HR, 1.65; 95% CI, 1.37-2.00), a fracture in the past year (HR, 3.63; 95% CI, 2.86-4.60), and proton pump inhibitor use (HR, 1.23; 95% CI, 1.04-1.45). After inclusion of vitamin D use, steroid use, time on dialysis, calcium levels, phosphate levels, presence of diabetes, rheumatoid arthritis, and chronic liver disease, the full model had an area under the curve of 77.7 at 1 year (95% CI, 73.3-84.4) and 69.9 at 3 years (95% CI, 68.0-72.2). For hip fracture, the model had an AUC of 80.1 at 1 year (95% CI, 77.0-83.5) and 71.9 at 3 years (95% CI, 70.1-74.2).

During the Q&A session, Dr. Cowan was asked how the tool could be implemented clinically. She said that it could have value in discussing fracture prediction and prevention with patients, but it could also increase fracture risk awareness among nephrologists. “I need to convince a lot of my colleagues because they’re focused on other things, so having this [calculator] I think is both good from a patient as well as a practitioner perspective. And the treatments that we have in people with end-stage renal disease are limited, so you want to know that you’re really targeting the high-risk person before you potentially put them on denosumab and increase the risk of severe hypercalcemia and things like that,” Dr. Cowan said.

The study points out the challenges of predicting fracture risk for specific populations, according to session comoderator Evelyn Hsieh, MD. She noted that the study needs follow-up. “I don’t think they had gotten to a validation [in a separate cohort] yet,” said Dr. Hsieh, an associate professor of medicine (rheumatology) and epidemiology (chronic diseases) at Yale University, New Haven, Conn.

Dr. Cowan and Dr. Hsieh have no relevant financial disclosures.

VANCOUVER – A new calculator that predicts short-term fracture risk at both 1 year and 3 years in patients on dialysis performed well in a study presented at the annual meeting of the American Society for Bone and Mineral Research.

The tool will soon be available on QxMD Calculate, which provides free decision-support tools for physicians, said presenter Andrea Cowan, MD, an assistant professor of medicine at the University of Western Ontario, London.

Dialysis patients have an approximately fivefold increased risk for fracture, Dr. Cowan noted, compared with the general population. However, treatments to prevent fracture risk are relatively limited and can have significant side effects. Therefore, “you really want to make sure that the person you’re targeting for treatment is actually going to be at a reasonable risk of fracture,” she said.

The Fracture Risk Assessment Tool (FRAX) is useful, but it estimates 10-year fracture risk, which is too long of a time frame to be useful for dialysis patients who experience a 50% 5-year mortality, according to Dr. Cowan. It does not take kidney failure or severe hyperparathyroidism into account, and it also requires information like bone mineral density, which poses an additional burden for a dialysis patient already undergoing multiple tests.

The new calculator could also be useful for research because it doesn’t rely on clinical data that might not be generally available, such as parental fracture, smoking status, or body mass index. “There’s a move towards things like pragmatic trials, which use more routinely collected data, have broader inclusion criteria, and are often more cost efficient to run. This calculator should be relatively easy to implement in trials using routinely collected data to perhaps define a subgroup of patients who may be at high risk of fracture without having to apply really cumbersome tools,” Dr. Cowan said.

The researchers included 11,599 patients between ages 40 and 89 years who were treated at a single center in Ontario between 2010 and 2017. The mean age was 66.18 years, 38.6% were women, 64.1% had diabetes, 11.9% had liver disease, and median time on dialysis was 0.81 years. The patients’ median parathyroid hormone level was 30 pmol/L.

At 3 years, the cumulative incidence of any fracture was 7.36% (95% confidence interval, 6.89-7.85), including 2.62% for hip fracture (95% CI, 2.34-2.93), 1.36% for spine fracture (95% CI, 1.16-1.59), 1.93% for wrist or forearm (95% CI, 1.69-2.20), and 2.15% for the pelvis (95% CI, 1.89-2.43). The incidence for all fractures at 1 year was 2.93 (95% CI, 2.62-3.26).

Variables associated with fracture risk included female sex (hazard ratio, 1.46; 95% CI, 1.27-1.67), a previous fracture more than 1 year in the past (HR, 1.65; 95% CI, 1.37-2.00), a fracture in the past year (HR, 3.63; 95% CI, 2.86-4.60), and proton pump inhibitor use (HR, 1.23; 95% CI, 1.04-1.45). After inclusion of vitamin D use, steroid use, time on dialysis, calcium levels, phosphate levels, presence of diabetes, rheumatoid arthritis, and chronic liver disease, the full model had an area under the curve of 77.7 at 1 year (95% CI, 73.3-84.4) and 69.9 at 3 years (95% CI, 68.0-72.2). For hip fracture, the model had an AUC of 80.1 at 1 year (95% CI, 77.0-83.5) and 71.9 at 3 years (95% CI, 70.1-74.2).

During the Q&A session, Dr. Cowan was asked how the tool could be implemented clinically. She said that it could have value in discussing fracture prediction and prevention with patients, but it could also increase fracture risk awareness among nephrologists. “I need to convince a lot of my colleagues because they’re focused on other things, so having this [calculator] I think is both good from a patient as well as a practitioner perspective. And the treatments that we have in people with end-stage renal disease are limited, so you want to know that you’re really targeting the high-risk person before you potentially put them on denosumab and increase the risk of severe hypercalcemia and things like that,” Dr. Cowan said.

Key clinical point: Ultrasound assessment of individuals with painful ankles revealed that abnormalities of the flexor retinacula (FR) were more common in patients with psoriatic arthritis (PsA) vs rheumatoid arthritis (RA).

Major finding: The FR were thicker in patients with PsA vs patients with RA and control individuals (0.96 vs 0.64 and 0.56, respectively; both P < .001), with abnormalities, such as retinaculitis (39.0% vs 2.7%), hypoechogenicity (46.0% vs 6.8%), power Doppler positivity (43.0% vs 8.1%), and periostosis (43.0% vs 8.1%), being significantly more prevalent in patients with PsA vs RA (all P < .001).

Study details: Findings are from a cross-sectional observational study including patients with PsA (n = 23) and RA (n = 37) who reported painful ankles and control individuals (n = 20) without rheumatic disease or ankle pain.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Key clinical point: This Mendelian randomization (MR) analysis established that there exists no causal association between psoriatic arthritis (PsA) and the genetic risk for skin cancer.

Major finding: PsA did not increase the genetic susceptibility to cutaneous squamous cell carcinoma (odds ratio [OR] 1.00; P = .214) and cutaneous melanoma (OR 1.00; P = .477). Although PsA decreased the genetic risk for basal cell carcinoma (OR 0.94; P = .016), the association disappeared when skin cancer risk factors like skin tanning, radiation-related disorders, and telomere length were considered.

Study details: Findings are from a multivariate MR analysis including 3186 patients with PsA and 240,862 control individuals without PsA.

Disclosures: This study was supported by the Natural Science Foundation of China and the Youth Science Foundation of Xiangya Hospital. The authors declared no conflicts of interest.

Key clinical point: Difficult-to-treat (D2T) psoriatic arthritis (PsA), a condition characterized by the failure of ≥2 targeted synthetic or biologic disease-modifying antirheumatic drugs (ts/bDMARD), is associated with a higher prevalence of axial involvement, structural damage, and treatment discontinuation.

Major finding: Peripheral structural damage (odds ratio [OR] 2.57; P = .020), axial involvement (OR 2.37; P = .035), and the discontinuation of bDMARD due to poor dermatological control (OR 2.99; P = .008) were more prevalent in patients with D2T PsA vs non-D2T PsA.

Study details: Findings are from a retrospective cohort study including 150 patients with PsA who initiated treatment with ts/bDMARD and were followed up for ≥2 years, of whom 49 patients had D2T PsA.

Disclosures: This study did not receive any funding. Three authors declared receiving honorary fees or research grants or serving as advisory board members for various sources.

Key clinical point: Approximately one-third of patients with psoriatic arthritis (PsA) reported a diagnostic delay of >2 years, which can be attributed to a number of clinical and demographic factors.

Major finding: The mean diagnostic delay period was 35.1 months. A diagnostic delay of >2 years was seen in 32.98% of patients, with the occurrence of arthritis symptoms before skin manifestations (odds ratio [OR] 1.72; 95% CI 1.20-2.46) and low back pain at first visit (OR 1.60; 95% CI 1.21-2.11) being significant factors associated with this delay. However, generalized-type psoriasis was negatively associated with the diagnostic delay of >2 years (OR 0.25; 95% CI 0.07-0.98).

Study details: Findings are from a cross-sectional study including 1134 patients with PsA.

Disclosures: This study did not disclose any funding source. The authors declared no conflicts of interest.

Key clinical point: In patients with active psoriatic arthritis (PsA) and imaging-confirmed sacroiliitis, 100 mg guselkumab every 4 weeks (Q4W) or every 8 weeks (Q8W) yielded clinically meaningful and sustained improvements in axial symptoms through 2 years.

Major finding: At week 24, guselkumab Q4W and Q8W vs placebo showed significantly greater least-squares mean improvements (−2.5 and −2.4, respectively, vs −1.2; P < .001) in the total Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, with further improvements in the mean total BASDAI score for each group at week 100 (~3.0 points).

Study details: This post hoc analysis of the DISCOVER-2 study included 246 biologic-naive patients with active PsA and sacroiliitis who were randomized to guselkumab Q4W (n = 82), guselkumab Q8W (n = 68), or placebo with crossover to guselkumab Q4W at week 24 (n = 96).
