Key clinical point: Inflammatory and metabolic parameters, including visceral adiposity, potentially contribute to subclinical coronary artery disease (CAD) in patients with psoriatic arthritis (PsA).

Major finding: CAD was significantly associated with visceral adiposity (standardized β 0.681; P = .002), and fluorodeoxyglucose (FDG) uptake in the bone marrow (standardized β 0.488; P = .008), liver (standardized β 0.619; P < .001), spleen (standardized β 0.523; P = .004), and subcutaneous adipose tissue (standardized β 0.524; P = .003). Visceral (P = .005) and subcutaneous (P = .004) adiposity and liver FDG uptake (P = .03) were higher in patients with PsA vs. controls without PsA.

Study details: Findings are from a cross-sectional analysis of a prospective study including 39 patients with biologic-naive PsA and 56 age-sex matched controls without PsA.

Key clinical point: Compared with the general population, patients with psoriatic arthritis (PsA) had a higher prevalence of cardiovascular events (CVE) and cardiovascular risk factors (CVRF) in real-life conditions, with CVRF being higher in patients with PsA as estimated using either SCORE-PsA or QRISK2-PsA cardiovascular risk algorithms.

Major finding: Patients with PsA vs. controls had a higher prevalence of CVE (8.7% vs. 4.1%; P = .03) and CVRF, such as high body mass index (26.6 vs. 25.2; P = .001), triglyceride level (1.24 vs. 1.06; P = .001) and hypertension (34.4% vs. 26.3%; P = .03). The proportion of patients with PsA who were estimated to have a very high CVRF (≥10%) increased when SCORE (25.4% to 27.4%) and QRISK2 (44.9% to 53.2%) equations considered the additional risk attributable to PsA.

Study details: Findings are from an observational, cross-sectional, case-control study including 207 patients with PsA and 414 matched controls.

Telemedicine for patients with liver disease has made progress in recent years, but some key hurdles remain. Strategies that rely on patient ownership of mobile devices or reliable internet access will likely miss patients who have the greatest need for remote access.

This is one of the conclusions from a county-by-county study of access to liver specialty care and mortality, using data drawn from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiological Research (WONDER). The study was led by Jacqueline B. Henson, MD, of the Division of Gastroenterology, department of medicine, Duke University, Durham, N.C., and published in Hepatology.
 

Low-access areas

“Ultimately, no single telehealth strategy will be successful in all areas, and these will need to be tailored at the local and state level,” the authors wrote. “They will also depend on the persistence of policy changes enacted during the pandemic which made use and reimbursement for telehealth less restrictive.”

The researchers found that 69.5% of American counties had no gastrointestinal physicians. Moreover, 41.1% of counties were more than 100 miles away from a liver transplant (LT) center; 33.7% had no GI physicians and were more than 100 miles from a LT center. These categories represented populations of 48.8 million, 53.7 million, and 17.8 million. These counties had higher poverty rates, more unemployment, and lower educational attainment than did those that had GI physicians or were closer to LT centers. Distance from LT centers was associated with higher liver-related mortality (r = 0.24; P < .001) and density of GI providers (r = –0.12; P < .001).

Reduced access to specialty care for liver disease was also associated with decreased access to technology, including cell phones, smart phones, and internet service. Among counties in the highest death quartile and lowest access to care, 35.5% of households had no computer, 43.1% had no home internet, and only 19.2% of these had internet at broadband speeds.

“Use of platforms with lower internet speed requirements and that are compatible with mobile devices may help extend access, as could partnerships with local primary care and GI clinics,” they concluded. Further work should be done at the local and state levels to better understand the optimal strategies to reach their populations of need.
 

Missing ‘baseline ingredients’

Commenting on the study, Nancy Reau, MD, professor of medicine and chief of hepatology at Rush University Medical Center, Chicago, said that “anyone who takes care of vulnerable populations, whether elderly individuals or those who may be socioeconomically disadvantaged, realizes that we have to improve access to medical resources, and telehealth is certainly an attractive way of doing that.”

She added that a key message from the study is that attempts to improve access to disadvantaged populations, no matter how well-intentioned, are likely to provide the most benefit to those who have more resources than others. For example, not everyone has access to a smart phone or tablet: “Even if you have a tablet [or cell phone], you might have to go to the public library to get high speed internet, or you may not even have a public library. So, when something sounds like a great idea, such as expanding the academic footprint or access to integrative medicine through something like a virtual option, a lot of the individuals that you are targeting may not be able to engage,” said Dr. Reau.

For those working to expand access, it’s critical to get the perspective of underserved communities and remember that every patient is unique. Physicians may treat patients who are poor, or from disadvantaged areas, who nevertheless have successful telehealth visits. But that doesn’t mean everyone’s experience will be similar. “You can’t use those who have been successful in accessing telemedicine as an example for everyone else. Just because one person can do it doesn’t mean that everyone else can. Involving a practitioner or an advocate from the area that you’re trying to reach is imperative,” she explained.

The COVID-19 pandemic led to a big push for telehealth, and it may be tempting to believe that the transition to telehealth has been smooth. This study “demonstrates in a very granular way that a large number of Americans have no access to high-speed internet, or if they do, many don’t have access to the tools that would let them engage this way. You can’t make assumptions and use them to build a product,” continued Dr. Reau.

Innovative options are needed, such as working with primary care providers in rural or disadvantaged areas to setup pop-up hot spots where e-consultations could be performed. Working directly with broadband internet providers to set up access in specific locations for telehealth, or using products like Amazon Echo Show as a portal for telehealth, can also be tried. “Think about being innovative and recognize that these areas probably don’t have the baseline ingredients we thought they had,” suggested Dr. Reau.

The authors reported having no financial support. Dr. Reau has no relevant financial disclosures.

Among counties in the highest death quartile and lowest access to care, 35.5% of households had no computer, 43.1% had no home internet, and only 19.2% of these had internet at broadband speeds.

“Use of platforms with lower internet speed requirements and that are compatible with mobile devices may help extend access, as could partnerships with local primary care and GI clinics,” they concluded. Further work should be done at the local and state levels to better understand the optimal strategies to reach their populations of need.
 

Missing ‘baseline ingredients’

Commenting on the study, Nancy Reau, MD, professor of medicine and chief of hepatology at Rush University Medical Center, Chicago, said that “anyone who takes care of vulnerable populations, whether elderly individuals or those who may be socioeconomically disadvantaged, realizes that we have to improve access to medical resources, and telehealth is certainly an attractive way of doing that.”

She added that a key message from the study is that attempts to improve access to disadvantaged populations, no matter how well-intentioned, are likely to provide the most benefit to those who have more resources than others. For example, not everyone has access to a smart phone or tablet: “Even if you have a tablet [or cell phone], you might have to go to the public library to get high speed internet, or you may not even have a public library. So, when something sounds like a great idea, such as expanding the academic footprint or access to integrative medicine through something like a virtual option, a lot of the individuals that you are targeting may not be able to engage,” said Dr. Reau.

For those working to expand access, it’s critical to get the perspective of underserved communities and remember that every patient is unique. Physicians may treat patients who are poor, or from disadvantaged areas, who nevertheless have successful telehealth visits. But that doesn’t mean everyone’s experience will be similar. “You can’t use those who have been successful in accessing telemedicine as an example for everyone else. Just because one person can do it doesn’t mean that everyone else can. Involving a practitioner or an advocate from the area that you’re trying to reach is imperative,” she explained.

The COVID-19 pandemic led to a big push for telehealth, and it may be tempting to believe that the transition to telehealth has been smooth. This study “demonstrates in a very granular way that a large number of Americans have no access to high-speed internet, or if they do, many don’t have access to the tools that would let them engage this way. You can’t make assumptions and use them to build a product,” continued Dr. Reau.

Innovative options are needed, such as working with primary care providers in rural or disadvantaged areas to setup pop-up hot spots where e-consultations could be performed. Working directly with broadband internet providers to set up access in specific locations for telehealth, or using products like Amazon Echo Show as a portal for telehealth, can also be tried. “Think about being innovative and recognize that these areas probably don’t have the baseline ingredients we thought they had,” suggested Dr. Reau.

Telemedicine for patients with liver disease has made progress in recent years, but some key hurdles remain. Strategies that rely on patient ownership of mobile devices or reliable internet access will likely miss patients who have the greatest need for remote access.

This is one of the conclusions from a county-by-county study of access to liver specialty care and mortality, using data drawn from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiological Research (WONDER). The study was led by Jacqueline B. Henson, MD, of the Division of Gastroenterology, department of medicine, Duke University, Durham, N.C., and published in Hepatology.
 

Low-access areas

“Ultimately, no single telehealth strategy will be successful in all areas, and these will need to be tailored at the local and state level,” the authors wrote. “They will also depend on the persistence of policy changes enacted during the pandemic which made use and reimbursement for telehealth less restrictive.”

The researchers found that 69.5% of American counties had no gastrointestinal physicians. Moreover, 41.1% of counties were more than 100 miles away from a liver transplant (LT) center; 33.7% had no GI physicians and were more than 100 miles from a LT center. These categories represented populations of 48.8 million, 53.7 million, and 17.8 million. These counties had higher poverty rates, more unemployment, and lower educational attainment than did those that had GI physicians or were closer to LT centers. Distance from LT centers was associated with higher liver-related mortality (r = 0.24; P < .001) and density of GI providers (r = –0.12; P < .001).

Reduced access to specialty care for liver disease was also associated with decreased access to technology, including cell phones, smart phones, and internet service. Among counties in the highest death quartile and lowest access to care, 35.5% of households had no computer, 43.1% had no home internet, and only 19.2% of these had internet at broadband speeds.

Key clinical point: A higher proportion of patients with psoriatic arthritis (PsA) receiving 15 mg upadacitinib achieved low disease activity (LDA) or remission after the first 6 months of treatment, with the difference being visible even after 1 year of treatment, compared to those who received a placebo.

Major finding: At week 24, a higher proportion of patients receiving 15 mg upadacitinib vs. placebo achieved Disease Activity in PsA LDA (range 35%-48% vs. 4%-16%; P < .05) and remission (range 7%-11% vs. 0%-3%; P < .05), with the responses sustained until 56 weeks.

Study details: This was a post hoc analysis of the SELECT-PsA 1 and SELECT-PsA 2 trials including 1386 adults with PsA and prior inadequate response/intolerance to ≥1 non-biologic or biologic disease-modifying antirheumatic drugs who were randomly assigned to receive upadacitinib (15 or 30 mg), adalimumab, or placebo.

Key clinical point: A substantial proportion of patients with psoriatic arthritis (PsA) achieved resolution of enthesitis within a year of initiating nonsteroidal anti-inflammatory drugs (NSAID) or disease-modifying antirheumatic drugs (DMARD), although the odds were lower in patients with high joint disease activity at baseline.

Major finding: Complete resolution of enthesitis was achieved by 86.12% of patients within a mean period of 8.73 months from therapy initiation, with higher joint activity at baseline being associated with a lower chance of enthesitis resolution (odds ratio 0.97; P = .01).

Study details: Findings are from a retrospective analysis of prospectively collected data of 526 patients with PsA and enthesitis who received no treatment/only NSAID (n = 142), conventional DMARD ± NSAID but without targeted DMARD (n = 196), or targeted DMARD with or without other medications (n = 188).

Similar to a phenomenon already well documented in women, inadequate nutrition appears to be linked to hormonal abnormalities and potentially preventable tibial cortical bone density loss in athletic men, according to results of a small, prospective study.

Based on these findings, “we suspect that a subset of male runners might not be fueling their bodies with enough nutrition and calories for their physical activity,” reported Melanie S. Haines, MD, at the annual meeting of the Endocrine Society.

This is not the first study to suggest male athletes are at risk of a condition equivalent to what has been commonly referred to as the female athlete triad, but it enlarges the objective data that the phenomenon is real, and it makes insufficient availability of energy the likely cause.

In women, the triad is described as a lack of adequate stored energy, irregular menses, and bone density loss. In men, menstrual cycles are not relevant, of course, but this study like others suggests a link between the failure to maintain adequate stores of energy, disturbances in hormone function, and decreased bone density in both men and women, Dr. Haines explained.
 

RED-S vs. male or female athlete triad

“There is now a move away from the term female athlete triad or male athlete triad,” Dr. Haines reported. Rather the factors of failing to maintain adequate energy for metabolic demands, hormonal disturbances, and bone density loss appear to be relevant to both sexes, according to Dr. Haines, an endocrinologist at Massachusetts General Hospital and assistant professor of medicine at Harvard Medical School, both in Boston. She said several groups, including the International Olympic Committee (IOC), have transitioned to the term RED-S to apply to both sexes.

“RED-S is an acronym for relative energy deficiency in sport, and it appears to be gaining traction,” Dr. Haines said in an interview.

According to her study and others, excessive lean body mass from failure to supply sufficient energy for physiological needs “negatively affects hormones and bone,” Dr. Haines explained. In men and women, endocrine disturbances are triggered when insufficient calories lead to inadequate macro- and micronutrients.

In this study, 31 men aged 16-30 years were evaluated. Fifteen were in the athlete group, defined by running at least 30 miles per week for at least the previous 6 months. There were 16 control subjects; all exercised less than 2 hours per week and did not participate in team sports, but they were not permitted in the study if their body mass index exceeded 27.5 kg/m².
 

Athletes vs. otherwise healthy controls

Conditions that affect bone health were exclusion criteria in both groups, and neither group was permitted to take medications affecting bone health other than dietary calcium or vitamin D supplements for 2 months prior to the study.

Tibial cortical porosity was significantly greater – signaling deterioration in microarchitecture – in athletes, compared with control subjects (P = .003), according to quantitative computed tomography measurements. There was also significantly lower tibial cortical bone mineral density (P = .008) among athletes relative to controls.

Conversely, tibial trabecular measures of bone density and architecture were better among athletes than controls, but this was expected and did not contradict the hypothesis of the study.

“Trabecular bone refers to the inner part of the bone, which increases with weight-bearing exercise, but cortical bone is the outer shell, and the source of stress fractures,” Dr. Haines explained.

The median age of both the athletes and the controls was 24 years. Baseline measurements were similar. Body mass index, fat mass, estradiol, and leptin were all numerically lower in the athletes than controls, but none were significant, although there was a trend for the difference in leptin (P = .085).
 

Hormones correlated with tibial failure load

When these characteristics were evaluated in the context of mean tibial failure load, a metric related to strength, there was a strongly significant positive association with lean body mass (R = 0.85; P < 0.001) and estradiol level (R = 0.66; P = .007). The relationship with leptin also reached significance (R = 0.59; P = .046).

Unexpectedly, there was no relationship between testosterone and tibial failure load. The reason is unclear, but Dr. Haines’s interpretation is that the relationship between specific hormonal disturbances and bone density loss “might not be as simple” as once hypothesized.

The next step is a longitudinal evaluation of the same group of athletes to follow changes in the relationship between these variables over time, according to Dr. Haines.

Eventually, with evidence that there is a causal relationship between nutrition, hormonal changes, and bone loss, the research in this area will focus on better detection of risk and prophylactic strategies.

“Intervention trials to show that we can prevent stress factors will be difficult to perform,” Dr. Haines acknowledged, but she said that preventing adverse changes in bone at relatively young ages could have implications for long-term bone health, including protection from osteoporosis later in life.

The research presented by Dr. Haines is consistent with an area of research that is several decades old, at least in females, according to Siobhan M. Statuta, MD, a sports medicine primary care specialist at the University of Virginia, Charlottesville. The evidence that the same phenomenon occurs in men is more recent, but she said that it is now well accepted the there is a parallel hormonal issue in men and women.

“It is not a question of not eating enough. Often, athletes continue to consume the same diet, but their activity increases,” Dr. Statuta explained. “The problem is that they are not supplying enough of the calories they need to sustain the energy they are expending. You might say they are not fueling their engines appropriately.”

In 2014, the International Olympic Committee published a consensus statement on RED-S. They described this as a condition in which a state of energy deficiency leads to numerous complications in athletes, not just osteoporosis. Rather, a host of physiological systems, ranging from gastrointestinal complaints to cardiovascular events, were described.
 

RED-S addresses health beyond bones

“The RED-S theory is better described as a spoke-and-wheel concept rather than a triad. While inadequate energy availability is important to both, RED-S places this at the center of the wheel with spokes leading to all the possible complications rather than as a first event in a limited triad,” Dr. Statuta said in an interview.

However, she noted that the term RED-S is not yet appropriate to replace that of the male and female athlete triad.

“More research is required to hash out the relationship of a body in a state of energy deficiency and how it affects the entire body, which is the principle of RED-S,” Dr. Statuta said. “There likely are scientific effects, and we are currently investigating these relationships more.”

“These are really quite similar entities but have different foci,” she added. Based on data collected over several decades, “the triad narrows in on two body systems affected by low energy – the reproductive system and bones. RED-S incorporates these same systems yet adds on many more organ systems.

The original group of researchers have remained loyal to the concept of the triad that involves inadequate availability of energy followed by hormonal irregularities and osteoporosis. This group, the Female and Male Athlete Triad Coalition, has issued publications on this topic several times. Consensus statements were updated last year.

“The premise is that the triad leading to bone loss is shared by both men and women, even if the clinical manifestations differ,” said Dr. Statuta. The most notable difference is that men do not experience menstrual irregularities, but Dr. Statuta suggested that the clinical consequences are not necessarily any less.

“Males do not have menstrual cycles as an outward marker of an endocrine disturbance, so it is harder to recognize clinically, but I think there is agreement that not having enough energy available is the trigger of endocrine changes and then bone loss is relevant to both sexes,” she said. She said this is supported by a growing body of evidence, including the data presented by Dr. Haines at the Endocrine Society meeting.

Dr. Haines and Dr. Statuta report no potential conflicts of interest.

Conditions that affect bone health were exclusion criteria in both groups, and neither group was permitted to take medications affecting bone health other than dietary calcium or vitamin D supplements for 2 months prior to the study.

Tibial cortical porosity was significantly greater – signaling deterioration in microarchitecture – in athletes, compared with control subjects (P = .003), according to quantitative computed tomography measurements. There was also significantly lower tibial cortical bone mineral density (P = .008) among athletes relative to controls.

Conversely, tibial trabecular measures of bone density and architecture were better among athletes than controls, but this was expected and did not contradict the hypothesis of the study.

“Trabecular bone refers to the inner part of the bone, which increases with weight-bearing exercise, but cortical bone is the outer shell, and the source of stress fractures,” Dr. Haines explained.

The median age of both the athletes and the controls was 24 years. Baseline measurements were similar. Body mass index, fat mass, estradiol, and leptin were all numerically lower in the athletes than controls, but none were significant, although there was a trend for the difference in leptin (P = .085).
 

Hormones correlated with tibial failure load

When these characteristics were evaluated in the context of mean tibial failure load, a metric related to strength, there was a strongly significant positive association with lean body mass (R = 0.85; P < 0.001) and estradiol level (R = 0.66; P = .007). The relationship with leptin also reached significance (R = 0.59; P = .046).

Unexpectedly, there was no relationship between testosterone and tibial failure load. The reason is unclear, but Dr. Haines’s interpretation is that the relationship between specific hormonal disturbances and bone density loss “might not be as simple” as once hypothesized.

The next step is a longitudinal evaluation of the same group of athletes to follow changes in the relationship between these variables over time, according to Dr. Haines.

Eventually, with evidence that there is a causal relationship between nutrition, hormonal changes, and bone loss, the research in this area will focus on better detection of risk and prophylactic strategies.

“Intervention trials to show that we can prevent stress factors will be difficult to perform,” Dr. Haines acknowledged, but she said that preventing adverse changes in bone at relatively young ages could have implications for long-term bone health, including protection from osteoporosis later in life.

The research presented by Dr. Haines is consistent with an area of research that is several decades old, at least in females, according to Siobhan M. Statuta, MD, a sports medicine primary care specialist at the University of Virginia, Charlottesville. The evidence that the same phenomenon occurs in men is more recent, but she said that it is now well accepted the there is a parallel hormonal issue in men and women.

“It is not a question of not eating enough. Often, athletes continue to consume the same diet, but their activity increases,” Dr. Statuta explained. “The problem is that they are not supplying enough of the calories they need to sustain the energy they are expending. You might say they are not fueling their engines appropriately.”

In 2014, the International Olympic Committee published a consensus statement on RED-S. They described this as a condition in which a state of energy deficiency leads to numerous complications in athletes, not just osteoporosis. Rather, a host of physiological systems, ranging from gastrointestinal complaints to cardiovascular events, were described.
 

RED-S addresses health beyond bones

“The RED-S theory is better described as a spoke-and-wheel concept rather than a triad. While inadequate energy availability is important to both, RED-S places this at the center of the wheel with spokes leading to all the possible complications rather than as a first event in a limited triad,” Dr. Statuta said in an interview.

However, she noted that the term RED-S is not yet appropriate to replace that of the male and female athlete triad.

“More research is required to hash out the relationship of a body in a state of energy deficiency and how it affects the entire body, which is the principle of RED-S,” Dr. Statuta said. “There likely are scientific effects, and we are currently investigating these relationships more.”

“These are really quite similar entities but have different foci,” she added. Based on data collected over several decades, “the triad narrows in on two body systems affected by low energy – the reproductive system and bones. RED-S incorporates these same systems yet adds on many more organ systems.

The original group of researchers have remained loyal to the concept of the triad that involves inadequate availability of energy followed by hormonal irregularities and osteoporosis. This group, the Female and Male Athlete Triad Coalition, has issued publications on this topic several times. Consensus statements were updated last year.

“The premise is that the triad leading to bone loss is shared by both men and women, even if the clinical manifestations differ,” said Dr. Statuta. The most notable difference is that men do not experience menstrual irregularities, but Dr. Statuta suggested that the clinical consequences are not necessarily any less.

“Males do not have menstrual cycles as an outward marker of an endocrine disturbance, so it is harder to recognize clinically, but I think there is agreement that not having enough energy available is the trigger of endocrine changes and then bone loss is relevant to both sexes,” she said. She said this is supported by a growing body of evidence, including the data presented by Dr. Haines at the Endocrine Society meeting.

Dr. Haines and Dr. Statuta report no potential conflicts of interest.
