Industry-sponsored research funding has fallen by more than 20% from 2014 to 2022, according to a new analysis.

“Despite the growing partnerships and networks between rheumatologists, the public sector, and the health care industry to optimize research funding allocations, the declining trend in industry-sponsored research payments is a concerning sign for all rheumatologists,” writes study author Anju Murayama, an undergraduate medical student at the Tohoku University School of Medicine in Sendai City, Japan. The data suggest that “more and more rheumatologists are facing difficulties in obtaining research funding from the health care industry.”

Dr. Murayama used the Open Payments Database, which contains records of payments made by drug and pharmaceutical companies to health care providers. The analysis included research payments provided directly to rheumatologists (direct-research payments) and payments given to clinicians or health care organizations related to research whose principal investigator was a rheumatologist (associated-research payments). These associated payments included costs for study enrollment and screening, safety monitoring committees, research publication, and more.

The research was published August 15 in The Journal of Rheumatology .

In 2014, the total direct payments to rheumatologists from industry were $1.4 million. These payments jumped to nearly $4.6 million in 2016 but have declined since. In 2022, there were $976,481 in total payments, a 31% drop from 9 years before.

The U.S. Food and Drug Administration has approved canakinumab (Ilaris) for the treatment of gout flares in adults who cannot be treated with NSAIDs, colchicine, or repeated courses of corticosteroids. The drug is also indicated for people who could not tolerate or had an inadequate response to NSAIDs or colchicine.

The drug, a humanized anti–interleukin-1 beta monoclonal antibody, is the first and only biologic approved in the United States for the treatment of gout flares, according to Novartis. It is administered in a single, subcutaneous injection of 150 mg.

“At Novartis, we are committed to bringing medicines that address high unmet needs to patients. We are proud to receive approval on our eighth indication for Ilaris in the U.S. and provide the first biologic medicine option for people with gout flares to help treat this painful and debilitating condition,” the company said in a statement to this news organization.

Canakinumab was first approved in the United States in 2009 for the treatment of children and adults with cryopyrin-associated periodic syndrome (CAPS). Since then, it has been approved for the treatment of several other autoinflammatory diseases, including Still’s disease and recurrent fever syndromes.

In 2011, an FDA advisory panel voted against the approval of canakinumab to treat acute gout flares refractory to NSAIDs, colchicine, or repeated courses of corticosteroids, while in 2013, the European Medicine Agency approved the drug for this treatment indication.

Since that FDA advisory committee meeting and the FDA’s subsequent rejection letter, “[Novartis] has conducted additional studies in patients with gout flares and other related populations to further characterize the short- and long-term safety of canakinumab supporting the current application. To further support the benefit-risk [profile of the drug], the indication is for a more restricted population than initially proposed in 2011,” the FDA’s Center for Drug Evaluation and Research said in a statement to this news organization. “Given these considerations and the available safety information, the Agency determined that canakinumab, at the recommended dosage, has a favorable risk-benefit profile” in the specified patient population.

The Diagnosis: Flagellate Dermatitis

Upon further questioning by dermatology, the patient noted recent ingestion of shiitake mushrooms, which were not a part of his typical diet. Based on the appearance of the rash in the context of ingesting shiitake mushrooms, our patient was diagnosed with flagellate dermatitis. At 6-week followup, the patient’s rash had resolved spontaneously without further intervention.

Flagellate dermatitis usually appears on the torso as linear whiplike streaks.¹ The eruption often is pruritic and may be preceded by severe pruritus. Flagellate dermatitis also is a well-documented complication of bleomycin sulfate therapy with an incidence rate of 8% to 66%.²

Other chemotherapeutic causes include peplomycin, bendamustine, docetaxel, cisplatin, and trastuzumab.³ Flagellate dermatitis also is seen in some patients with dermatomyositis.⁴ A thorough patient history, including medications and dietary habits, is necessary to differentiate flagellate dermatitis from dermatomyositis.

Flagellate dermatitis, also known as shiitake dermatitis, is observed as erythematous flagellate eruptions involving the trunk or extremities that present within 2 hours to 5 days of handling or consuming undercooked or raw shiitake mushrooms (Lentinula edodes),^5,6 as was observed in our patient. Lentinan is the polysaccharide component of the shiitake species and is destabilized by heat.⁶ Ingestion of polysaccharide is associated with dermatitis, particularly in Japan, China, and Korea; however, the consumption of shiitake mushrooms has increased worldwide, and cases increasingly are reported outside of these typical regions. The rash typically resolves spontaneously; therefore, treatment is supportive. However, more severe symptomatic cases may require courses of topical corticosteroids and antihistamines.⁶

In our case, the differential diagnosis consisted of acute urticaria, cutaneous dermatomyositis, dermatographism, and maculopapular cutaneous mastocytosis. Acute urticaria displays well-circumscribed edematous papules or plaques, and individual lesions last less than 24 hours. Cutaneous dermatomyositis includes additional systemic manifestations such as fatigue, malaise, and myalgia, as well as involvement of the gastrointestinal, respiratory, or cardiac organs. Dermatographism is evoked by stroking or rubbing of the skin, which results in asymptomatic lesions that persist for 15 to 30 minutes. Cases of maculopapular cutaneous mastocytosis more often are seen in children, and the histamine release most often causes gastrointestinal tract symptoms such as nausea, vomiting, and diarrhea, as well as flushing, blushing, pruritus, respiratory difficulty, and malaise.

The timing of complete revascularization (CR) in patients with acute ST-elevation myocardial infarction (STEMI) and multivessel disease (MVD) may make little clinical difference.

The conclusion comes from a randomized outcomes trial of 840 patients that compared prompt same-session CR with a staged procedure carried out weeks later.

That CR is a worthy goal in such cases is largely settled, unlike the question of when to pursue revascularization of nonculprit lesions for best results. So the timing varies in practice, often depending on the patient’s clinical stability, risk status, or practical issues like cath lab resources or personnel.

The new trial, MULTISTARS-AMI, supports that kind of flexibility as safe in practice. Immediate, same-session CR led to a 48% drop in risk for a broad composite primary endpoint at 1 year, compared with staged CR an average of 37 days later. The finding was significant for noninferiority in the study’s primary analysis and secondarily, was significant for superiority (P < .001 in both cases).

The composite endpoint included death from any cause, MI, stroke, unplanned ischemia-driven revascularization, or heart failure (HF) hospitalization.

CR’s immediate effect on outcomes was numerically pronounced, but because it was prespecified as a noninferiority trial, MULTISTARS-AMI could show only that the strategy is comparable to staged CR, emphasized Barbara E. Stähli, MD, MPH, MBA, at a press conference.

Still, it appears to be the first trial of its kind to show that operators and patients can safely choose either percutaneous coronary intervention (PCI) approach and attain similar outcomes, said Dr. Stähli, University Hospital Zurich, MULTISTARS-AMI’s principal investigator.

Not only were the two approaches similar with respect to safety, she noted, but immediate CR seemed to require less use of contrast agent and fluoroscopy. “And you have only one procedure, so there’s only one arterial puncture.”

Dr. Stähli formally presented MULTISTARS-AMI at the annual congress of the European Society of Cardiology, held in Amsterdam. She is also lead author on its publication in the New England Journal of Medicine.

After her presentation, invited discussant Robert A. Byrne, PhD, MD, MB, BCh, said that the trial’s central message is that STEMI patients with MVD having primary PCI “should undergo complete revascularization within the first 45 days, with the timing of the non–infarct-related artery procedure individualized according to clinical risk and logistical considerations.”

Still, the trial “provides evidence, but not strong evidence, of benefits with routine immediate PCI during the index procedure as compared with staged outpatient PCI,” said Dr. Byrne, Mater Private Hospital and RCSI University of Medicine and Health Sciences, Dublin.

MULTISTARS-AMI randomly assigned patients at 37 European sites to undergo same-session CR (418 patients) or CR staged 19-45 days later (422 patients).

Rates for the primary endpoint at 1 year were 8.5% and 16.3%, respectively, for a risk ratio of 0.52 (95% confidence interval, 0.38-0.72). The difference was driven by fewer instances of nonfatal MI, 0.36 (95% CI, 0.16-0.80), and unplanned ischemia-driven revascularization, 0.42 (95% CI, 0.24-0.74), in the immediate-CR group.
 

The wee hours

Sunil V. Rao, MD, director of interventional cardiology at NYU Langone Health System, New York, said that, in general at his center, patients who are stable with a good primary PCI outcome and whose lesions aren’t very high risk are often discharged to return later for the staged CR procedure.

But after the new insights from MULTISTARS-AMI, Dr. Rao, who is not connected to the study, said in an interview that immediate same-session CR is indeed likely preferable to staged CR performed weeks later.

Same-session CR, however, may not always be practical or wise, he observed. For example, some patients with STEMI can be pretty sick with MVD that involves very complex lesions that might be better handled later.

“The wee hours of the night may not be the best time to tackle such complex lesions,” Dr. Rao observed. If confronted with, for example, a bifurcation that requires a complex procedure, “2 o’clock in the morning is probably not the best time to address something like that.”

So the trial’s more realistic translational message, he proposed, may be to perform CR after the primary PCI but during the same hospitalization, “unless there are some real mitigating circumstances.” 

The trial was supported by Boston Scientific. Dr. Stähli had no disclosures. Dr. Byrne discloses research funding to his institution from Abbott Vascular, Translumina, Biosensors, and Boston Scientific. Dr. Rao had no relevant disclosures.

AMSTERDAM – A simple, low-cost 5-day course of dietary inorganic nitrate has shown apparent overwhelming benefit in preventing contrast-induced nephropathy (CIN) and reducing subsequent renal and cardiovascular outcomes.

In the NITRATE-CIN Study, non-ST segment elevation myocardial infarction acute coronary syndrome (ACS) patients at risk of renal injury from coronary angiography who received dietary inorganic nitrates had a 70% reduction in CIN compared with those given placebo.

The nitrate group also showed an impressive reduction in periprocedural myocardial infarction (MI) and improved renal function at 3 months, as well as a halving of major adverse cardiovascular events and major adverse kidney events at 1 year.

The trial was presented by Dan Jones, MD, Barts Health NHS Trust, London, at the annual congress of the European Society of Cardiology.

“Currently, aside from intravenous hydration, there is no proven treatment that reduces contrast-induced nephropathy. We feel that dietary inorganic nitrate shows huge promise in this study, and these findings could have important implications in reducing this serious complication of coronary angiography,” Dr. Jones concluded.

He explained that the product used was a formulation of dietary inorganic nitrates given as potassium nitrate capsules, which the study investigators produced specifically for this trial.

At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.

However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.

“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.
 

Dietary nitrates “make sense”

Designated discussant of the NITRATE-CIN trial at the ESC Hotline session, Roxanna Mehran, MD, Icahn School of Medicine at Mount Sinai, New York, said the study was well designed, and the “interesting and plausible” hypothesis to raise nitric oxide levels by dietary nitrates “makes sense.”

On the main findings of a major significant 50% reduction in acute kidney injury, Dr. Mehran said, “It is difficult to imagine such a reduction is possible.”

She pointed out that the large reduction in major adverse cardiac events and major adverse kidney events at 1 year also suggests that there is a sustained benefit in protecting the kidney.

“We’re all going to get on beet juice after this,” she quipped.

Still, Dr. Mehran questioned whether the results were “too good to be true,” adding that a larger trial actually powered for longer term outcome events is needed, as well as a better understanding of whether CIN has a causative role in mortality.

Responding to questions about whether such a large effect could actually be achieved with dietary nitrates, Dr. Jones said he thought there would definitely be some benefits, but maybe not quite as large as those seen in this study.

“From our pilot data we thought nitrate may be effective in preventing CIN,” he said in an interview. “We recruited a higher risk group than we thought, which is why the control event rates were higher than we expected, but the acute kidney injury reduction is roughly what we had estimated, and makes sense biologically.”

Dr. Jones acknowledged that the large reductions in long-term major adverse cardiovascular and kidney events were unexpected.

“The trial was not powered to see reductions in these outcomes, so we need to see if those event reductions can be replicated in larger multicenter trials,” he said. “But this was a double-blind placebo-controlled trial so in this trial the effects are real, and I think the effect size in this trial is too large for there not to be a beneficial effect.

“But I’m not so sure that we would see the same magnitude of effect when we have a larger study with tighter confidence intervals but perhaps a 20%-25% reduction in cardiovascular and kidney may be more realistic, which would still be amazing for such an easy and cost-effective intervention,” Dr. Jones added.

A larger trial is now being planned.

The researchers are also working on the development of a commercial form of dietary inorganic nitrate that would be needed for larger multicenter studies and would then be generally available. “We want this to be a low-cost product that would be available to all,” Dr. Jones said.

He noted that other studies have shown that dietary inorganic nitrates in the form of beetroot juice lower blood pressure; there are suggestions it may also lower cholesterol and prevent stent restenosis, and athletes sometimes take it to increase their aerobic capacity.

“There appears to be many benefits of dietary nitrates, and the one thing we can do at this time is to encourage people to increase their dietary nitrate consumption by eating large quantities of green leafy vegetables and beetroot,” Dr. Jones said.
 

Replacing lost nitric oxide

In his presentation, Dr. Jones noted that CIN is a serious complication after coronary angiography and is associated with longer hospital stays, worse long-term kidney function, and increased risk of MI and death.

The incidence varies depending on patient risk and definitions used, but it can affect up to 50% of high-risk ACS patients – older patients and/or those with heart failure, chronic kidney disease, or diabetes.

“We don’t really understand the mechanisms that cause CIN, but multiple proposed mechanisms exist, and we know from previous studies that a deficiency of nitric oxide is crucial to the development of CIN,” he explained. “We also know that [nitric oxide] is crucial for normal renal hemostasis. Therefore, a potential therapeutic target to prevent CIN would be to replace this lost nitric oxide.”

The inorganic nitrate evaluated in this trial is found in the diet, is produced endogenously, and is different from medicinally synthesized organic nitrates such as isosorbide mononitrate, he said.

“Isosorbide mononitrate/dinitrate tablets contain organic nitrates and while they are good for angina, we know that they do not have the same beneficial effects on the sustained generation of nitric oxide as inorganic nitrates,” Dr. Jones added.
 

NITRATE-CIN study

NITRATE-CIN was a double-blind, randomized, placebo-controlled trial conducted at Queen Mary University of London and St. Bartholomew’s Hospital in London, which tested the effectiveness of inorganic nitrate in preventing contrast-induced nephropathy in 640 patients with non-ST elevation ACS referred for invasive coronary angiography.

To be eligible for the trial, patients had to be at risk of contrast-induced nephropathy with an estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m² or have two of the following significant risk factors: diabetes, liver failure, over 70 years of age, exposure to contrast within 7 days, heart failure, or on concomitant renally acting drugs.

Patients were randomly assigned to a formulation of potassium nitrate (12 mmol/744 mg nitrate) per day given as capsules for a 5-day course with the first dose administered prior to angiography or to a control group that received potassium chloride with a matched potassium concentration.

The patient population had a mean age of 71 years, 73% were male, 75% were White, 46% had diabetes, and 56% had chronic kidney disease. There was a 13% loss to follow-up, which was attributed to the COVID pandemic.

The amount of contrast administration was 180 mL in the placebo and 170 mL in the nitrate arm, with 50% of patients undergoing some sort of revascularization.

The primary endpoint was the incidence of CIN as defined by KDIGO criteria – a series of stages of acute kidney injury defined by changes in serum creatinine within 72 hours and up to 1 week.

Results showed that this primary CIN endpoint was reduced significantly from 30% in the placebo arm to 9.1% in the nitrate group, a 70% relative risk reduction (P < .0001). The majority (90%) of this CIN was stage 1, but 10% was stage 2.

Consistent results were seen when an alternative definition of CIN (Mehran) was used, although the rates in both arms were lower than when the KDIGO definition was used.

The benefit was seen across prespecified subgroups including diabetes status, troponin positivity, and Mehran risk. But the benefit seemed to be attenuated in patients on preexisting organic nitrate therapy, although the numbers in these groups were too small to draw definitive conclusions.

As would be expected, there were significant elevations in both systemic nitrate and nitrite levels both up to 72 hours after the procedure, which was consistent with the 5-day course. This was associated with reductions in systolic and diastolic blood pressure, but not associated with any adverse events, Dr. Jones reported.

Rates of procedural MI, a prespecified secondary endpoint, were reduced from 12.5% to 4.1% in those on inorganic nitrates (P = .003).

Looking at longer term outcomes, kidney function was improved at 3 months as measured by change in eGFR, which showed a 10% relative improvement of 5.2 mL/min per 1.73 m² (10%) in the nitrate group vs. the placebo group. Serum creatinine levels were also significantly increased in the nitrate group.

At 12 months, there was a significant 50% relative reduction in major adverse cardiovascular events – including all-cause mortality, recurrent MI, and recurrent revascularization – which were reduced from 18.1% in the placebo group to 9.1% in the nitrate group, with a reduction in all three of the constituent components of the composite endpoint including all-cause mortality.

Major adverse kidney events (all-cause mortality, renal replacement therapy, or persistent renal dysfunction) were also reduced at 12 months from 28.4% in the placebo group to 10.7% in the nitrate group (P < .0001), a 60% relative reduction. This was driven by lower rates of all-cause mortality and persistent renal dysfunction.

While Dr. Jones said these results on major cardiovascular and kidney outcomes should be viewed as hypothesis-generating at the present time, he said there were biological mechanisms that could explain these benefits.

“We saw a reduction in procedural MI, and we know there is a lot of similar biology in preventing procedural MI and subsequent cardiac events in the acute phase. This, in combination with the large reduction in acute kidney injury, could explain why there’s improved outcomes out to 12 months.”

In her comments, Dr. Mehran congratulated the investigators on having conducted the first study to have shown benefit in the prevention of contrast-associated acute kidney injury as well as major adverse cardiovascular and kidney events associated with the condition.

She used the term “contrast-associated acute kidney injury” rather than “contrast-induced nephropathy” because, she said, it has not been proven that the acute kidney injury seen after angiography is actually caused by the contrast and “so many other things are occurring during procedures when these patients are presenting with different syndromes.”

Dr. Mehran pointed out some weaknesses in the NITRATE-CIN study including the single-center design, the large volume of contrast administered, 13% of patients missing the primary endpoint blood draw, and an imbalance in relevant baseline characteristics despite randomization.

The NITRATE-CIN study was funded by Heart Research UK. Dr. Jones has disclosed no relevant financial relationships.

AMSTERDAM – A simple, low-cost 5-day course of dietary inorganic nitrate has shown apparent overwhelming benefit in preventing contrast-induced nephropathy (CIN) and reducing subsequent renal and cardiovascular outcomes.

In the NITRATE-CIN Study, non-ST segment elevation myocardial infarction acute coronary syndrome (ACS) patients at risk of renal injury from coronary angiography who received dietary inorganic nitrates had a 70% reduction in CIN compared with those given placebo.

The nitrate group also showed an impressive reduction in periprocedural myocardial infarction (MI) and improved renal function at 3 months, as well as a halving of major adverse cardiovascular events and major adverse kidney events at 1 year.

The trial was presented by Dan Jones, MD, Barts Health NHS Trust, London, at the annual congress of the European Society of Cardiology.

“Currently, aside from intravenous hydration, there is no proven treatment that reduces contrast-induced nephropathy. We feel that dietary inorganic nitrate shows huge promise in this study, and these findings could have important implications in reducing this serious complication of coronary angiography,” Dr. Jones concluded.

He explained that the product used was a formulation of dietary inorganic nitrates given as potassium nitrate capsules, which the study investigators produced specifically for this trial.

At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.

However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.

“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.

AMSTERDAM – Systematic screening by primary care physicians for cardiovascular disease (CVD) in high-risk adults – those with type 2 diabetes, chronic obstructive pulmonary disease (COPD), or both – more than doubled the rate of incident CVD diagnosed, compared with usual care, in a Dutch study involving more than 1,200 people and 25 primary care practices.

Scaling up this program to larger populations could potentially uncover huge numbers of currently unrecognized people with CVD given the large number of adults with type 2 diabetes plus those with COPD, Amy Groenewegen, MD, said at the annual congress of the European Society of Cardiology.

“I think this screening is ready for routine use, but it could be followed by prospective studies that investigate whether it produces more benefits in patient-centered outcomes,” Dr. Groenewegen said in a press briefing. She stressed that it has not yet been clearly proven that patients with these chronic diseases are better off long term when their CVD is detected sooner using the tested approach.

“We need simple ways to identify relevant patients for additional screening and potential treatment” of CVD, commented Lars Kober, MD, designated discussant at the Congress and a cardiologist and professor at Rigshospitalet, Copenhagen University Hospital.
 

A ‘very simple’ symptom questionnaire

The study is important because it tested a “very simple” symptom questionnaire as the initial screening phase, yet resulted in a CVD diagnostic rate that was two- to threefold higher than in the control patients managed with usual care, Dr. Kober noted.

The Reviving the Early Diagnosis of CVD (RED-CVD) trial randomized 14 primary care practices in the Netherlands to apply a structured screening protocol to adults with type 2 diabetes or COPD, and another 11 practices that served as controls and provided their patients with usual care.

The study included 624 people in the screening arm and 592 in the usual-care arm. Their average age was about 68 years. In the screening arm, 87% had type 2 diabetes and 20% had COPD, including 6.3% with both. In the usual-care arm, 86% had type 2 diabetes, 21% had COPD, with 7.4% having both.

About a quarter of the study cohort had a history of a CVD diagnosis, but they were included for their potential for developing another form of CVD. The study considered three types of CVD: coronary artery disease, heart failure, and atrial fibrillation.

The CVD screening protocol began with an 11-question survey, completed by patients, that asked about their symptoms. The survey was devised by a research team at the University Medical Center Groningen, the Netherlands, who collaborated on the study.

The second phase for people who had suggestive symptoms was a physical examination, measurement of serum N-terminal pro-brain natriuretic peptide (elevated levels signal incident heart failure), and an ECG. People who continued to show findings consistent with CVD in this phase were then referred on a discretionary basis by the attending physician to a specialist.
 

More than doubling the CVD diagnosis rate

The screening program produced a total of 50 new CVD diagnoses in the screening cohort (8%) and 18 in the control, usual-care arm (3%), for the study’s primary endpoint. The greatest number of events involved heart failure, followed by coronary disease.

The screening questionnaire identified 70% of the people who completed it with suggestive symptoms, such as shortness of breath, claudication, or palpitations. The follow-up assessments of phase two narrowed the group with possible new CVD down to 44% of the people in this arm, and the participating physicians referred 39% to a specialist.

An analysis that adjusted for several demographic and clinical variables and excluded nonobstructive coronary disease as a new CVD diagnosis showed that the systematic screening approach resulted in 2.4-fold more new diagnoses than usual care, reported Dr. Groenewegen, an epidemiologist at University Medical Center Utrecht, the Netherlands.

RED-CVD received no commercial funding. Dr. Groenewegen disclosed no relevant financial relationships. Dr. Kober has received honoraria from AstraZeneca, Bayer, Boehringer Ingelheim, Novartis, and Novo Nordisk.

AMSTERDAM – Systematic screening by primary care physicians for cardiovascular disease (CVD) in high-risk adults – those with type 2 diabetes, chronic obstructive pulmonary disease (COPD), or both – more than doubled the rate of incident CVD diagnosed, compared with usual care, in a Dutch study involving more than 1,200 people and 25 primary care practices.

Scaling up this program to larger populations could potentially uncover huge numbers of currently unrecognized people with CVD given the large number of adults with type 2 diabetes plus those with COPD, Amy Groenewegen, MD, said at the annual congress of the European Society of Cardiology.

“I think this screening is ready for routine use, but it could be followed by prospective studies that investigate whether it produces more benefits in patient-centered outcomes,” Dr. Groenewegen said in a press briefing. She stressed that it has not yet been clearly proven that patients with these chronic diseases are better off long term when their CVD is detected sooner using the tested approach.

“We need simple ways to identify relevant patients for additional screening and potential treatment” of CVD, commented Lars Kober, MD, designated discussant at the Congress and a cardiologist and professor at Rigshospitalet, Copenhagen University Hospital.
 

A ‘very simple’ symptom questionnaire

The study is important because it tested a “very simple” symptom questionnaire as the initial screening phase, yet resulted in a CVD diagnostic rate that was two- to threefold higher than in the control patients managed with usual care, Dr. Kober noted.

The Reviving the Early Diagnosis of CVD (RED-CVD) trial randomized 14 primary care practices in the Netherlands to apply a structured screening protocol to adults with type 2 diabetes or COPD, and another 11 practices that served as controls and provided their patients with usual care.

The study included 624 people in the screening arm and 592 in the usual-care arm. Their average age was about 68 years. In the screening arm, 87% had type 2 diabetes and 20% had COPD, including 6.3% with both. In the usual-care arm, 86% had type 2 diabetes, 21% had COPD, with 7.4% having both.

About a quarter of the study cohort had a history of a CVD diagnosis, but they were included for their potential for developing another form of CVD. The study considered three types of CVD: coronary artery disease, heart failure, and atrial fibrillation.

The CVD screening protocol began with an 11-question survey, completed by patients, that asked about their symptoms. The survey was devised by a research team at the University Medical Center Groningen, the Netherlands, who collaborated on the study.

The second phase for people who had suggestive symptoms was a physical examination, measurement of serum N-terminal pro-brain natriuretic peptide (elevated levels signal incident heart failure), and an ECG. People who continued to show findings consistent with CVD in this phase were then referred on a discretionary basis by the attending physician to a specialist.
 

More than doubling the CVD diagnosis rate

The American College of Rheumatology has released a summary of upcoming guidelines on screening, monitoring, and treatment for interstitial lung disease (ILD) in patients with systemic autoimmune rheumatic disease.

The recommendations apply to adults with rheumatic diseases at greater risk for ILD: rheumatoid arthritis, systemic sclerosis (SSc), mixed connective tissue disease (MCTD), Sjögren’s disease (SjD), and idiopathic inflammatory myopathies (IIM).

“Interstitial lung disease is a major cause of morbidity and mortality across several systemic autoimmune rheumatic diseases,” Sindhu R. Johnson, MD, PhD, lead author of the new guidelines and director of the clinical epidemiology and health care research program at the University of Toronto, said in an ACR press release. “Guidance was needed for which tests to use for screening and monitoring this particular disease.”

The two documents are summaries of part of a larger manuscript currently awaiting peer review, according to the ACR, and the final guidelines are anticipated to be published by early 2024.

The recommendations were developed using “the best available evidence and consensus across a range of expert opinions and incorporated patient values and preferences,” according to the press release.

Highlights of recommendations for screening and monitoring ILD are:

• Providers can screen patients at higher risk for ILD with pulmonary function tests (PFTs) and high-resolution CT of the chest.
• PFTs, chest high-resolution CT, and ambulatory desaturation testing are conditionally recommended for monitoring ILD progression.
• It is conditionally recommended that providers do not use 6-minute walk test distance, chest radiography, or bronchoscopy for screening or monitoring disease.
• It is suggested that patients with IIM-ILD and SSc-ILD receive PFTs for monitoring every 3-6 months during the first year, then less frequently once stable.
• It is suggested that patients with RA-ILD, SjD-ILD, and MCTD-ILD receive PFTs every 3-12 months for the first year, then less frequently once stable.

Suggestions on how often to screen for ILD were not present in the summary documents, but will be made available in the larger manuscript, said Elana Bernstein, MD, director of the Columbia University Medical Center/New York–Presbyterian Hospital scleroderma program, New York. She is co–first author of the guidelines.

Nearly all recommendations are conditional, primarily because the certainty of evidence behind many of these recommendations is low or very low, she said in an interview. More clinical data on ILD in patients with rheumatic disease would help strengthen evidence, she said, particularly for best practices in frequency of testing. “We need more research on how often patients should be screened for ILD and how often they should be monitored for ILD progression,” she said. “That would enable us to provide recommendations, rather than just suggestions.”

Highlights of recommendations for ILD treatment are:

• The guidelines strongly recommend against using glucocorticoids for first-line ILD treatment in patients with SSc-ILD.
• Short-term glucocorticoids are conditionally recommended as a first-line ILD treatment for patients with systemic autoimmune rheumatic disease–related ILD (SARD-ILD), excluding SSc-ILD.
• Mycophenolate, azathioprine, rituximab, and cyclophosphamide are all potential first-line ILD treatment options for patients with SARD-ILD.
• It is conditionally recommended that patients with SARD-ILD do not receive leflunomide, methotrexate, tumor necrosis factor inhibitors, or abatacept as first-line ILD treatment.
• If SARD-ILD progresses despite first-line therapy, mycophenolate, rituximab, cyclophosphamide, and nintedanib are potential secondary treatment options.
• If RA-ILD progresses following initial therapy, pirfenidone is a treatment option.
• The guidelines conditionally recommend against pirfenidone as a secondary treatment option for SARD-ILD other than RA-ILD.

These summary guidelines appear “comprehensive,” but there has yet to be information published on the basis of these recommendations, Elizabeth Volkmann, MD, said in an interview.

“It’s important to understand that we don’t know whether most of these recommendations were just driven by expert opinion versus actual evidence from randomized, controlled clinical trials,” said Dr. Volkmann, who codirects the connective tissue disease–related interstitial lung disease program at the University of California, Los Angeles. She was not involved with creating the guidelines.

She expects that many of the recommendations for first- and second-line ILD treatment options were based on expert opinion, as there have been no randomized clinical trials looking at that specific topic, she said. For example, nintedanib is conditionally recommended as a first-line treatment option for SSc-ILD, but as a second-line treatment for SjD-ILD, IIM-ILD, and MCTD-ILD. “There’s no literature to support one or the other – whether nintedanib is first-line or second-line [treatment].”

The decision to publish the summary recommendations online prior to peer review is unusual, she said, as these recommendations could be altered during that process; however, Dr. Bernstein noted that was not likely.

By releasing the summary guideline now, the ACR can “get the needed information to clinicians earlier as the manuscript goes through its remaining stages and is finalized,” an ACR representative explained.

Prior to the expected publication of these guidelines in early 2024, Dr. Volkmann noted that the American Thoracic Society will be publishing guidelines on the treatment of SSc-ILD in the American Journal of Respiratory and Critical Care Medicine in September.

Dr. Bernstein reported grants/contracts with the Department of Defense, the Scleroderma Research Foundation, the National Institutes of Health, Eicos, Boehringer Ingelheim, Kadmon, and Pfizer. Dr. Volkmann has received consulting and speaking fees from Boehringer Ingelheim and GlaxoSmithKline and institutional support for performing studies on systemic sclerosis for Kadmon, Boehringer Ingelheim, Horizon, and Prometheus.

The Food and Drug Administration has granted two new clearances to Welldoc’s BlueStar digital health platform to enable personalized insulin dosing recommendations for people with type 1 or type 2 diabetes.

The latest clearance, announced on Aug. 23, enables the app-based platform to provide bolus insulin dose recommendations that are based on glucose and trend data from a compatible continuous glucose monitoring (CGM) device. On Aug. 15, the FDA cleared the BlueStar to use connected insulin dosing data in personalized bolus insulin dosing recommendations.

“Welldoc is the first company to receive clearance for a CGM-informed bolus calculator specifically designed for adults who manage their diabetes with multiple daily injections of insulin,” according to a company statement.

“With this clearance, Welldoc is filling a significant gap for people who require complex insulin regimens. By connecting directly with CGM data and using both glucose values and trend arrows, the BlueStar solution will provide precise and in-the-moment insulin dosing guidance directly to individuals, helping them reach their glucose targets,” endocrinologist Grazia Aleppo, MD, of Northwestern University, Chicago, said in the statement.

The new features extend the platform’s existing digital diet and lifestyle coaching capabilities. Previous FDA clearances included expansions to use most types of available insulins, including bolus and premixed insulin titration for patients with type 2 diabetes, in September 2021 and for basal insulin adjustment in June 2020.

Dr. Aleppo was a principal investigator in Welldoc’s clinical validation study for BlueStar.

The number of gender-affirming surgeries performed in the United States nearly tripled between 2016 and 2019, a trend driven in part by changes in federal and state laws mandating coverage of the procedures, a new study published in JAMA Network Open found.

Breast and chest surgeries were the most common procedures performed, and the number of surgical procedures carried out increased with age. The researchers said that, in addition to legal shifts, the established safety of the surgeries and resulting increase in quality of life may also help explain the increase.

“The point of this is to raise awareness and to really document the patterns of care in the United States,” said Jason Wright, MD, an associate professor at Columbia University, New York. “We hope that people understand that these procedures are being performed more commonly and they’re out there.”

A study published in 2022 in JAMA Pediatrics found that the number of chest reconstruction surgeries among U.S. adolescents rose fourfold between 2016 and 2019.

The new study included data from 2016 to 2020 in the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample. More than 48,000 patients with diagnosis codes for gender identity disorder, transsexualism, or a personal history of sex reassignment were identified. Age ranges were grouped as 12-18 (7.7%), 19-30 (52.3%), and 31-40 (21.8%).

The number of gender-affirming procedures rose from 4,552 in 2016 to a peak of 13,011 in 2019. (A slight decline to 12,818 procedures in 2020 was attributed to the COVID-19 pandemic.) The surgeries were grouped into three categories: breast and chest procedures, which occurred in 56.6% of patients; genital reconstructive surgeries (35.1%), and other facial cosmetic procedures (13.9%).

Undocumented uptick

In addition to more inclusive health insurance, Dr. Wright said the increase in these procedures can also be attributed to studies showing their safety and the long-term association with high patient satisfaction.

Kevin Wang, MD, medical director of Providence–Swedish Health Services’ LGBTQIA+ program in Seattle, agreed that changes in health insurance coverage for gender-affirming surgery likely account in part for their increase. But he added that more clinicians are performing these procedures.

He said gender-affirming surgeries improve quality of life for the people who undergo them. The American Academy of Pediatrics has said it would be conducting a thorough review of the effects of transgender care on youth. A 2018 policy statement from the group said transgender youth should “have access to comprehensive, gender-affirming, and developmentally appropriate health care that is provided in a safe and inclusive clinical space.”

Dr. Wright cited several limitations to his group’s study that may result in the undercapture of transgender individuals and gender-affirming surgery; in particular, while the study captured inpatient and ambulatory surgical procedures in large, nationwide datasets, a small number of the procedures could have been performed in other settings.

Guiding a patient through gender-affirming care and surgical procedures can be an arduous process, including understanding their goals, using hormone therapy, and making referrals to specialists. Dr. Wang said he works to maximize his patients’ physical, mental, and emotional health, and helps them understand the risks.

He cited the double standard of a cisgender woman wanting breast augmentation without justification, but someone who identifies as transgender has many more boxes to check – for example, seeing a behavior health specialist to demonstrate they understand the risks and securing a letter of support from their primary care physician to undergo a similar procedure.

“It’s just interesting how the transgender community has to jump through so many more barriers and hoops for affirming, lifesaving procedures where you have other people who are doing it for aesthetic purposes and do not require any type of authorization,” Dr. Wang said.

Dr. Wright said he hopes the findings call attention to the need for more professionals working in the gender-affirming care field.

“I think for the medical community, it’s important to raise the idea that these procedures are becoming more common,” Dr. Wright said. “We are going to need specialists who have expertise in transgender care and surgeons who have the ability to perform these operations. Hopefully, this sheds light on the resources that are going to be required to care for these patients going forward.”

The number of gender-affirming surgeries performed in the United States nearly tripled between 2016 and 2019, a trend driven in part by changes in federal and state laws mandating coverage of the procedures, a new study published in JAMA Network Open found.

Breast and chest surgeries were the most common procedures performed, and the number of surgical procedures carried out increased with age. The researchers said that, in addition to legal shifts, the established safety of the surgeries and resulting increase in quality of life may also help explain the increase.

“The point of this is to raise awareness and to really document the patterns of care in the United States,” said Jason Wright, MD, an associate professor at Columbia University, New York. “We hope that people understand that these procedures are being performed more commonly and they’re out there.”

A study published in 2022 in JAMA Pediatrics found that the number of chest reconstruction surgeries among U.S. adolescents rose fourfold between 2016 and 2019.

The new study included data from 2016 to 2020 in the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample. More than 48,000 patients with diagnosis codes for gender identity disorder, transsexualism, or a personal history of sex reassignment were identified. Age ranges were grouped as 12-18 (7.7%), 19-30 (52.3%), and 31-40 (21.8%).

The number of gender-affirming procedures rose from 4,552 in 2016 to a peak of 13,011 in 2019. (A slight decline to 12,818 procedures in 2020 was attributed to the COVID-19 pandemic.) The surgeries were grouped into three categories: breast and chest procedures, which occurred in 56.6% of patients; genital reconstructive surgeries (35.1%), and other facial cosmetic procedures (13.9%).

Undocumented uptick

In addition to more inclusive health insurance, Dr. Wright said the increase in these procedures can also be attributed to studies showing their safety and the long-term association with high patient satisfaction.

Kevin Wang, MD, medical director of Providence–Swedish Health Services’ LGBTQIA+ program in Seattle, agreed that changes in health insurance coverage for gender-affirming surgery likely account in part for their increase. But he added that more clinicians are performing these procedures.

He said gender-affirming surgeries improve quality of life for the people who undergo them. The American Academy of Pediatrics has said it would be conducting a thorough review of the effects of transgender care on youth. A 2018 policy statement from the group said transgender youth should “have access to comprehensive, gender-affirming, and developmentally appropriate health care that is provided in a safe and inclusive clinical space.”

Dr. Wright cited several limitations to his group’s study that may result in the undercapture of transgender individuals and gender-affirming surgery; in particular, while the study captured inpatient and ambulatory surgical procedures in large, nationwide datasets, a small number of the procedures could have been performed in other settings.

Guiding a patient through gender-affirming care and surgical procedures can be an arduous process, including understanding their goals, using hormone therapy, and making referrals to specialists. Dr. Wang said he works to maximize his patients’ physical, mental, and emotional health, and helps them understand the risks.

He cited the double standard of a cisgender woman wanting breast augmentation without justification, but someone who identifies as transgender has many more boxes to check – for example, seeing a behavior health specialist to demonstrate they understand the risks and securing a letter of support from their primary care physician to undergo a similar procedure.

“It’s just interesting how the transgender community has to jump through so many more barriers and hoops for affirming, lifesaving procedures where you have other people who are doing it for aesthetic purposes and do not require any type of authorization,” Dr. Wang said.

A simple urine test can accurately diagnose urothelial carcinoma as well as predict the risk for recurrence for those under surveillance, according to findings from a recent validation study.

The urinary comprehensive genomic profiling (uCGP) assay (UroAmp, Convergent Genomics) had a specificity of 95% and sensitivity of 90% for an initial diagnosis of urothelial carcinoma in patients with hematuria – identifying 95 of 100 people with urothelial carcinoma and 90 of 100 patients without the disease.

For patients under surveillance for urothelial cancer recurrence, the test was six times more accurate than traditional clinical risk factors for predicting recurrence.

“Considering its performance in multiple areas of urothelial carcinoma diagnosis and monitoring, uCGP shows great promise to enhance delivery of risk-stratified care,” Keyan Salari, MD, PhD, director of the prostate cancer genetics program at Massachusetts General Hospital in Boston, and colleagues wrote in a study published in Clinical Cancer Research.

“The idea is that this could be used as kind of a first-pass screening tool for patients with hematuria that could potentially obviate the need for undergoing imaging such as CT scans or cystoscopy,” Dr. Salari said in an interview.

The uCGP test is a next-generation sequencing assay that identifies mutations in 60 genes associated with bladder cancer. An earlier analysis evaluating the test as a potential screening tool focused on 10 key genes covered in the assay. The study found the test accurately predicted future bladder cancer in 66% of urine samples, including some that had been collected more than a decade prior to being tested.

In the current case-control study, Dr. Salari and colleagues used a total of 581 samples – 333 samples for classifying disease and developing algorithms for initial diagnosis, surveillance, and molecular-grade prediction, as well as 248 samples for blinded validation. The test’s performance was evaluated by calculating sensitivity, specificity, positive predictive value, and negative predictive value.

Overall, the test demonstrated a specificity of 95% and sensitivity of 90% for an initial urothelial carcinoma diagnosis, but performed even better for the most aggressive tumors, with 100% sensitivity for diagnosing high-grade urothelial carcinoma and muscle-invasive tumors.

On the diagnosis front, the test had a positive predictive value of 88% and a negative predictive value of 99%.

Among patients under surveillance, the test predicted the risk of recurrence significantly better than standard clinical risk factors (hazard ratio, 6.2). The test demonstrated a positive predictive value similar to that observed for cytology (45% vs. 42%) but a much higher sensitivity (79% vs. 25%). The test also demonstrated a negative predictive value of 91% for recurrence.

The molecular-grade algorithm performed well, with a positive predictive value for high-grade disease of 88% and a specificity of 95% in the validation cohort.

Overall, “uCGP enables noninvasive, accurate urothelial carcinoma diagnosis and risk stratification in both hematuria and urothelial carcinoma surveillance patients,” the authors concluded. The test is not currently reimbursed by Medicare, but negotiations with third-party payers are reportedly underway.

The study was supported by the National Cancer Institute. Dr. Salari reported grants from Convergent Genomics during the conduct of the study as well as grants from Urology Care Foundation and Prostate Cancer Foundation, and personal fees from OrigiMed outside the submitted work. Several coauthors are employees and stockholders of Convergent Genomics.
