BOSTON — A Mediterranean diet with extra virgin olive oil (EVOO) significantly reduced the risk for tachyarrhythmia recurrence after atrial fibrillation (AF) ablation in patients with paroxysmal disease, but the diet had less of an impact on patients with persistent AF, a new study showed.

“An intervention with the Mediterranean diet with EVOO produced a nonsignificant reduction in any atrial tachycardia in a selected population after undergoing atrial fibrillation ablation, but this intervention produced a significant reduction in any atrial tachyarrhythmias in patients with paroxysmal AF,” said Maria Teresa Barrio-Lopez, MD, PhD, an electrophysiologist at University Hospital HM Monteprincipe in Madrid, Spain, who presented results from the PREDIMAR trial at the Heart Rhythm Society (HRS) 2024 annual meeting.

The PREDIMAR study enrolled 720 patients from the larger PREDIMED study, which showed that patients without AF at enrollment and who followed a Mediterranean diet enriched with EVOO had a 38% lower rate of incidental AF than control individuals.

PREDIMAR evaluated the impact of the diet on arrhythmia recurrence in patients after ablation. The patients were randomized in a 1:1 ratio to either the dietary intervention group or the control group.
 

PREDIMAR Study Results

The overall difference in the rate of AF recurrence in the 3-18 months after ablation between the dietary intervention and control groups was nonsignificant (34.8% vs 37.5%).

However, among the 431 patients with paroxysmal AF, 25.2% in the diet group and 34.7% in the control group had no tachyarrhythmia recurrence, which translates into a 31% lower risk in the diet group.

In this study, the diet was rich in fish, nuts, fruits, and vegetables and was complemented with EVOO. Participants were also permitted moderate wine consumption.

The intervention involved dietitians who remotely followed patients and made periodic telephone calls to encourage them to stay on the diet. Participants had weight and body measurements taken at baseline and at 3, 6, 12, and 18 months and underwent an ECG at 6, 12, and 18 months. Labs were obtained at baseline and at 12 months. Participants were also given educational materials throughout the intervention.

Average scores, based on a scale of 0-13, excluding an item for wine intake, were 7.8 in the diet group and 7.2 in the control group.

Daily average alcohol intake was higher in the diet group than in the control group (9.8 vs 8.2 g), but “the weight of the patient during the study didn’t change in any group,” Dr. Barrio-Lopez reported.

Baseline characteristics were similar in the two groups. About 60% were taking antiarrhythmic drugs, and about 84% were taking anticoagulants.
 

‘A Tour de Force’

PREDIMAR was “really a tour de force,” Christine Albert, MD, MPH, chair of cardiology at the Smidt Heart Institute at the Cedars-Sinai Medical Center in Los Angeles, California, said during a commentary presented at HRS. “We talk about how we’re going to do these dietary interventions and weight loss and all the risk-factor reduction, and they pulled it off with 700 individuals and also did it in a way that was very novel.”

This is the first large-scale dietary intervention trial of patients with AF. However, Dr. Albert noted later in an interview, the Mediterranean diet poses potential challenges for some people with AF.

“The Mediterranean diet recommends that people drink wine, but then there’s clear evidence that abstinence from alcohol actually reduces recurrences of atrial fibrillation, so even though there are a lot of things about the Mediterranean diet that are probably healthy and good for atrial fibrillation, that aspect of it might be working against the patient,” she explained.

The finding that patients in the Mediterranean diet group experienced no significant weight loss could be counterintuitive when it comes to preventing AF. But “you could adapt the diet for AF,” Dr. Albert said. You could “leave out the wine and focus more on weight loss if the patient is obese because those are also the pillars of what we’ve learned for patients with atrial fibrillation.”

Making weight loss a key component of the study could be significant for the American population. “At least in the United States, that’s a huge part of the risk factors for atrial fibrillation after ablation,” she said.

The remote follow-up component of the PREDIMAR study is also intriguing. “I think what’s most exciting about what they did is, they showed they can do all these things remotely,” Dr. Albert added.

Dr. Barrio-Lopez had no relevant financial relationships. Dr. Albert disclosed relationships with Abbott, Roche Diagnostics, St. Jude Medical, Boston Scientific, Medtronic, and Element Science.

BOSTON — Patients who have had a stroke are thought to be at a higher risk for another one, but oral anticoagulation with edoxaban led to no discernible reduction in the risk for a second stroke, and the risk for major bleeding was more than quadruple the risk with no anticoagulation, a subanalysis of a major European trial has shown.

“There is no interaction between prior stroke or TIA [transient ischemic attack] and the treatment effect, and this is true for the primary outcome and the safety outcome,” Paulus Kirchoff, MD, director of cardiology at the University Heart and Vascular Center in Hamburg, Germany, said during his presentation of a subanalysis of the NOAH-AFNET 6 trial at the annual meeting of the Heart Rhythm Society (HRS) 2024. However, “there is a signal for more safety events in patients randomized to anticoagulation with a prior stroke.”

The subanalysis involved 253 patients who had had a stroke or TIA and who had device-detected atrial fibrillation (AF) from the overall NOAH-AFNET 6 population of 2536 patients, which enrolled patients 65 years and older with at least one additional CHA2DS-VASc risk factor and patients 75 years and older with device-detected subclinical AF episodes of at least 6 minutes. Patients were randomized to either edoxaban or no anticoagulation, but 53.9% of the no-anticoagulation group was taking aspirin at trial enrollment. Anticoagulation with edoxaban was shown to have no significant impact on stroke rates or other cardiovascular outcomes.
 

Subanalysis Results

In the subanalysis, a composite of stroke, systemic embolism, and cardiovascular death — the primary outcome — was similar in the edoxaban and no-anticoagulation groups (14/122 patients [11.5%] vs 16/131 patients [12.2%]; 5.7% vs 6.3% per patient-year).

The rate of recurrent stroke was also similar in the edoxaban and no-anticoagulation groups (4 of 122 patients [3.3%] vs 6 of 131 patients [4.6%]; 1.6% vs 2.3% per patient-year). And there were eight cardiovascular deaths in each group.

However, edoxaban patients had significantly higher rates of major bleeding.

“This is a subanalysis, so what we see in terms of the number of patients with events is not powered for a definitive answer, but we do see that there were 10 major bleeds in the group of patients with a prior stroke or TIA in NOAH,” Dr. Kirchoff reported. “Eight of those 10 major bleeds occurred in patients randomized to edoxaban.”

Results from the NOAH-AFNET 6 trial have been compared with those from the ARTESiA trial, which compared apixaban anticoagulation with aspirin in patients with subclinical AF and was also presented at HRS 2024. ARTESiA showed that apixaban significantly lowered the risk for stroke and systemic embolism.

“In ARTESiA, everyone was on aspirin when they were randomized to no anticoagulation; in NOAH, only about half were on aspirin,” Dr. Kirchoff said.

Both studies had similar outcomes for cardiovascular death in the anticoagulation and no-anticoagulation groups. “It’s not significant; it may be chance, but it’s definitely not the reduction in death that we have seen in the anticoagulant trials,” Dr. Kirchoff said. “When you look at the meta-analyses of the early anticoagulation trials, there’s a one third reduction in death, and here we’re talking about a smaller reduction.”

This research points to a need for a better way to evaluate stroke risk. “We need new markers,” Dr. Kirchoff said. “Some of them may be in the blood or imaging, genetics maybe, and one thing that really emerges from my perspective is that we now have the first evidence to suggest that patients with a very low atrial fibrillation burden have a low stroke rate.”

More research is needed to better understand AF characteristics and stroke risk, he said.
 

AF Care Enters a ‘Gray Zone’

The NOAH-AFNET 6 results, coupled with those from ARTESiA, are changing the paradigm for anticoagulation in patients with stroke, said Taya Glotzer, MD, an electrophysiologist at the Hackensack University Medical Center in Hackensack, New Jersey, who compiled her own analysis of the studies’ outcomes.

“In ARTESiA, the stroke reduction was only 0.44% a year, with a number needed to treat of 250,” she said. “In the NOAH-AFNET 6 main trial, the stroke reduction was 0.2%, with the number needed to treat of 500, and in the NOAH prior stroke patients, there was a 0.7% reduction, with a number needed to treat of 143.”

None of these trials would meet the standard for a class 1 recommendation for anticoagulation with a reduction of even 1%-2% per year, she noted, but they do show that the stroke rate “is very, very low” in prior patients with stroke.

“Prior to 2024, we knew what was black and white; we knew who to anticoagulate and who not to anticoagulate. And now we are in a gray zone, trying to balance the risk of stroke and bleeding. We have to individualize or hope for substudies, perhaps using the CHA2DS-VASc score or other information about the left atrium, to help us make decisions in these patients. It’s not just going to be black and white,” she said.

Dr. Kirchoff had no relevant financial relationships to disclose. Dr. Glotzer disclosed financial relationships with Medtronic, Abbott, Boston Scientific, and MediaSphere Medical.

LONG BEACH, CALIFORNIA — A small fraction of patients with pulmonary embolism (PE) who are eligible for advanced therapies are actually getting them, reported investigators who conducted a big data analysis.

“Advanced PE therapy seems to be vulnerable to disparate use, and perhaps underuse,” Sahil Parikh, MD, a cardiovascular interventionalist at the Columbia University Medical Center in New York, said when he presented results from the REAL-PE study at the Society for Cardiovascular Angiography and Interventions (SCAI) 2024 Scientific Sessions.

The underuse of advanced PE therapies is “the controversy,” Dr. Parikh said after his presentation. “It remains unclear what the role of invasive therapy is in the management of so-called high-intermediate–risk people. There isn’t a Class 1 guideline recommendation, and there is a very rapidly evolving trend that we’re increasingly treating these patients invasively,” he said.

“However, if you come to these meetings [such as SCAI], you might think everyone is getting one of these devices, but these data show that’s not the case,” Dr. Parikh said.

The analysis mined deidentified data from Truveta, a collective of health systems that provides regulatory-grade electronic health record data for research. The database included 105 million diagnoses made from January 1, 2018, to May 5, 2023; according to the diagnosis codes, 435,296 of these were for pulmonary embolism, and according to the procedure codes, 2072 patients — 0.48% of all patients with a PE diagnosis — received advanced therapy.

The researchers accessed data on patients treated with ultrasound-assisted catheter-directed thrombolysis or mechanical thrombectomy, identified from claims codes. Patient characteristics — age, race, ethnicity, sex, comorbidities, and diagnoses — were also accessed for the analysis. Earlier results were published in the January issue of the Journal of the Society for Cardiovascular Angioplasty Interventions. 
 

Less Intervention for Black Patients and Women

White patients were more likely to receive advanced therapy than were Black patients (0.5% vs 0.37%; P = .000), Dr. Parikh reported, and women were less likely to receive advanced therapy than were men (0.41% vs 0.55%; P = .000).

The only discernable differences in outcomes were in major bleeding events in the 7 days after the procedure, which affected more White patients than it did Black patients (13.9% vs 9.3%) and affected more women than it did men (16.6% vs 11.1%).

What’s noteworthy about this study is that it demonstrates the potential of advanced data analytics to identify disparities in care and outcomes, Dr. Parikh said during his presentation. “These analyses provide a means of evaluating disparities in real clinical practice, both in the area of PE and otherwise, and may also be used for real-time monitoring of clinical decision-making and decisional support,” he said. “We do think that both novel and established therapies can benefit equally from similar types of analyses.”
 

Big Data Signaling Disparities

“That’s where these data are helpful,” Dr. Parikh explained. They provide “a real snapshot of how many procedures are being performed and in what kinds of patients. The low number of patients getting the procedure would suggest that there are probably more patients who would be eligible for treatment based on some of the emerging consensus documents, and they’re not receiving them.”

The data are “hypotheses generating,” Dr. Parikh said in an interview. “These hypotheses have to be evaluated further in more granular databases.”

REAL-PE is also a “clarion call” for clinical trials of investigative devices going forward, he said. “In those trials, we need to endeavor to enroll enough women and men, minority and nonminority patients so that we can make meaningful assessments of differences in efficacy and safety.”

This study is “real proof that big data can be used to provide information on outcomes for patients in a very rapid manner; that’s really exciting,” said Ethan Korngold, MD, chair of structural and interventional cardiology at the Providence Health Institute in Portland, Oregon. “This is an area of great research with great innovation, and it’s proof that, with these type of techniques using artificial intelligence and big data, we can generate data quickly on how we’re doing and what kind of patients we’re reaching.”

Findings like these may also help identify sources of the disparities, Dr. Korngold added. 

“This shows we need to be reaching every patient with advanced therapies,” he said. “Different hospitals have different capabilities and different expertise in this area and they reach different patient populations. A lot of the difference in utilization stems from this fact,” he said.

“It just underscores the fact that we need to standardize our treatment approaches, and then we need to reach every person who’s suffering from this disease,” Dr. Korngold said.

LONG BEACH, CALIFORNIA — A small fraction of patients with pulmonary embolism (PE) who are eligible for advanced therapies are actually getting them, reported investigators who conducted a big data analysis.

“Advanced PE therapy seems to be vulnerable to disparate use, and perhaps underuse,” Sahil Parikh, MD, a cardiovascular interventionalist at the Columbia University Medical Center in New York, said when he presented results from the REAL-PE study at the Society for Cardiovascular Angiography and Interventions (SCAI) 2024 Scientific Sessions.

The underuse of advanced PE therapies is “the controversy,” Dr. Parikh said after his presentation. “It remains unclear what the role of invasive therapy is in the management of so-called high-intermediate–risk people. There isn’t a Class 1 guideline recommendation, and there is a very rapidly evolving trend that we’re increasingly treating these patients invasively,” he said.

“However, if you come to these meetings [such as SCAI], you might think everyone is getting one of these devices, but these data show that’s not the case,” Dr. Parikh said.

The analysis mined deidentified data from Truveta, a collective of health systems that provides regulatory-grade electronic health record data for research. The database included 105 million diagnoses made from January 1, 2018, to May 5, 2023; according to the diagnosis codes, 435,296 of these were for pulmonary embolism, and according to the procedure codes, 2072 patients — 0.48% of all patients with a PE diagnosis — received advanced therapy.

The researchers accessed data on patients treated with ultrasound-assisted catheter-directed thrombolysis or mechanical thrombectomy, identified from claims codes. Patient characteristics — age, race, ethnicity, sex, comorbidities, and diagnoses — were also accessed for the analysis. Earlier results were published in the January issue of the Journal of the Society for Cardiovascular Angioplasty Interventions. 
 

Less Intervention for Black Patients and Women

White patients were more likely to receive advanced therapy than were Black patients (0.5% vs 0.37%; P = .000), Dr. Parikh reported, and women were less likely to receive advanced therapy than were men (0.41% vs 0.55%; P = .000).

The only discernable differences in outcomes were in major bleeding events in the 7 days after the procedure, which affected more White patients than it did Black patients (13.9% vs 9.3%) and affected more women than it did men (16.6% vs 11.1%).

What’s noteworthy about this study is that it demonstrates the potential of advanced data analytics to identify disparities in care and outcomes, Dr. Parikh said during his presentation. “These analyses provide a means of evaluating disparities in real clinical practice, both in the area of PE and otherwise, and may also be used for real-time monitoring of clinical decision-making and decisional support,” he said. “We do think that both novel and established therapies can benefit equally from similar types of analyses.”
 

Big Data Signaling Disparities

“That’s where these data are helpful,” Dr. Parikh explained. They provide “a real snapshot of how many procedures are being performed and in what kinds of patients. The low number of patients getting the procedure would suggest that there are probably more patients who would be eligible for treatment based on some of the emerging consensus documents, and they’re not receiving them.”

The data are “hypotheses generating,” Dr. Parikh said in an interview. “These hypotheses have to be evaluated further in more granular databases.”

Artificial intelligence (AI) has drawn interest in ophthalmology for its potential to track disease trends in huge populations, such as the 38.4 million people in the United States with diabetes who are at risk for diabetic eye disease. However, a recent study using AI to detect diabetic retinopathy from retinal photo screenings has found wide disparities in the quality of data being fed into the algorithm.

And screening photos captured in nine primary care settings were three times more likely to be unusable than those obtained in two ophthalmology clinics, a study at Temple University in Philadelphia found. The results of the new research were reported at the Association for Research in Vision and Ophthalmology (ARVO) 2024 annual meeting.

“AI-assisted diabetic retinopathy screenings were more successful when completed in the ophthalmology clinic setting compared to the primary care setting,” study leader Madelyn Class, a medical student at Temple, told this news organization. One key difference, Ms. Class said, was that the specialty clinics used a photographer training in capturing ophthalmic images, while the primary care sites had medical assistants taking the photos.
 

Challenges of Screening in Primary Care

The American Diabetes Association acknowledged in a 2017 position statement that retinal photography has the potential to bring screening into settings where optometrists or ophthalmologists are unavailable. This study showed the potential may not yet be realized.

In the primary care setting, 42.5% of retinal photos were ungradable compared with 14.5% in the specialty settings.

The number of patients diagnosed with more-than-mild diabetic retinopathy also varied significantly between the two settings — 13% in primary care and 24% in ophthalmology — as did the rates of follow-up appointments: 58% and 80%, respectively.

“It seems user error played a role in the quality of photographs that were taken,” Ms. Class said. “Some of the images we received from the primary care settings were actually of the eyelid, or even the curtains on the wall, rather than the fundus.

“All the camera operators in the study received training on the imaging device,” Ms. Class added. “This suggests that some of the photographers were rushed, out of practice, or simply no longer interested in taking photos,” she said. “Apparently, we will have to continuously monitor the performance of each photographer to ensure that quality photos are being taken.”

The findings may also point to the need for using different equipment for screening in primary care, Ms. Class added. “Robotic as opposed to manual cameras may help eliminate some of the user error that was experienced with primary care screenings,” she said.

Need for Training ‘Fixable’

These findings demonstrate the challenges of capturing usable retinal images outside of an eye care professional’s office, according to Jennifer Lim, MD, director of the retina service at the University of Illinois Chicago.

“This study illustrates that implementation is the rub of AI,” Dr. Lim told this news organization. “Getting primary care doctors and clinics to want to adopt and figure out how to implement AI screening [for diabetic retinopathy] in a healthcare system is difficult, so I applaud the Temple University system for trying to integrate retinal photography-based AI screening into the primary care outpatient centers and comparing outcomes to the ophthalmology clinics.”

The study showed that photographers need not only initial training but also monitoring to avoid ungradable images, Dr. Lim added, a problem that is “fixable.”

“It’s going to take a lot of work to get the message out to the primary care practices that these autonomous, cloud-based systems are available and effective for detecting retinopathy,” she said.

But the effort is worth it, she added: “It doesn’t take much time to take these photos for diabetic retinopathy screening, and the potential benefits are huge because the earlier you diagnose diabetic retinopathy that’s more than mild, the more likely the patient can be sent for eye care in a timely fashion and thus prevent visual loss from diabetic retinopathy.”

Ms. Class had no relevant disclosures. Dr. Lim disclosed a past relationship with Eyenuk, the maker of retinal screening cameras.

NEW YORK — Urate, the culprit of gout, affects the vasculature in multiple ways that can raise cardiovascular risk (CV) in an individual with gout, and following guidelines for gout treatment, including the use of colchicine, can be the key to reducing those risks.

“Guideline-concordant gout treatment, which is essentially an anti-inflammatory urate-lowering strategy, at least improves arterial physiology and likely reduces cardiovascular risk,” Michael H. Pillinger, MD, told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference. Dr. Pillinger is professor of medicine and biochemistry and molecular pharmacology at New York University Grossman School of Medicine, New York City, who has published multiple studies on gout.

brojideclewrapricrewronicrauodespeposaprelarewrinochatinestubolephiuuclegesposhutihibrotimathorakichalerucluceneswuvugapishifrabraswajurespasorulobrumuresp

He cited evidence that has shown soluble urate stimulates the production of C-reactive protein (CRP), which is a predictor of cardiovascular disease (CVD). Another study, in which Dr. Pillinger participated, demonstrated that gout patients have impaired vascular endothelial function associated with a chronic, low-level inflammatory state, he said.

“There’s good evidence that urate itself affects the vasculature in multiple ways, and I suspect this may be a model for other metabolic effects on vasculature,” Dr. Pillinger said. “Patients with gout have abnormal endothelium in ways that really convey vascular risk.”
 

Gout, Inflammation, and CVD

However, for rheumatologists to study the association between gout-related inflammation and CVD is “very, very hard,” Dr. Pillinger added. “But I do think that the mechanisms by which gout induces biological changes in the vasculature may provide insights into cardiovascular disease in general.”

One way to evaluate the effects of gout on the endothelium in the clinic is to measure flow-mediated dilation. This technique involves placing an ultrasound probe over the brachial artery and measuring the baseline artery diameter. Then, with the blood pressure cuff over the forearm, inflate it to reduce flow, then release the cuff and measure the brachial artery diameter after the endothelium releases vasodilators.

Dr. Pillinger and colleagues evaluated this technique in 34 patients with gout and 64 controls and found that patients with gout had an almost 50% decrease in flow-mediated dilation, he said. “Interestingly, the higher the urate, the worse the flow; the more the inflammation, the worse the flow, so seemingly corresponding with the severity of the gout,” he said. That raised an obvious question, Dr. Pillinger continued: “If you can treat the gout, can you improve the flow-mediated dilation?”

His group answered that question with a study in 38 previously untreated patients with gout, giving them colchicine 0.6 mg twice daily for a month plus a urate-lowering xanthine oxidase inhibitor (allopurinol or febuxostat) to treat them to a target urate level of < 6 mg/dL. “We saw an increase in endothelial function, and it normalized,” Dr. Pillinger said.

However, some study participants didn’t respond. “They were people with well-established other cardiovascular comorbidities — hypertension, hyperlipidemia,” he said. “I think some people just have vessels that are too damaged to get at them just by fixing their gout problem or their inflammation.”

That means patients with gout need to be treated with colchicine early on to avoid CV problems, Dr. Pillinger added. “We ought to get to them before they have the other problems,” he said.

Managing gout, and the concomitant CV problems, requires vigilance both during and in between flares, Dr. Pillinger said after his presentation.

“We have always taught that patients between flares basically look like people with no gout, but we do know now that patients with gout between flares tend to have what you might call ‘subclinical’ inflammation: CRPs and ESRs [erythrocyte sedimentation rates] that are higher than those of the general population, though not so excessive that they might grab attention,” he said. “We also know that many, if not all, patients between flares have urate deposited in or around their joints, but how these two relate is not fully established.”

Better treatment within 3 months of an acute gout flare may reduce the risk for CV events, he said, but that’s based on speculation more so than clinical data.
 

Potential Benefits of Targeting Inflammation

“More chronically, we know from the cardiologists’ studies that anti-inflammatory therapy should reduce risk in the high-risk general population,” Dr. Pillinger said. “There are no prospective studies confirming that this approach will work among gout patients, but there is no reason why it shouldn’t work — except perhaps that gout patients may have higher inflammation than the general population and also have more comorbidities, so they could perhaps be more resistant.”

Dr. Pillinger said that his group’s studies and another led by Daniel Solomon, MD, at Brigham and Women’s Hospital in Boston, have indicated that anti-inflammatory strategies in gout will lower CV risk.

“And interestingly,” he added, “our data suggest that colchicine use may lower risk not only in high-risk gout patients but also in gout patients who start with no CAD [coronary artery disease] but who seem to have less incident CAD on colchicine. I see this as identifying that gout patients are intrinsically at high risk for CAD, even if they don’t actually have any, so they represent a population for whom lowering chronic inflammation may help prevent incident disease.”

Dr. Pillinger provided more evidence that the understanding of the relationship between gout, gout flares, and CV risk is evolving, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone, New York City.

“There’s epidemiologic evidence supporting the association,” Dr. Garshick told this news organization after the conference. “We think that most conditions with immune system activation do tend to have an increased risk of some form of cardiovascular disease, but I think the relationship with gout has been highly underpublicized.”

Many patients with gout tend to have a higher prevalence of traditional cardiometabolic issues, which may compound the relationship, Dr. Garshick added. “However, I would argue that with this patient subset that it doesn’t matter because gout patients have a higher risk of traditional risk factors, and you have to [treat-to-target] those traditional risk factors.”

While the clinical evidence of a link between gout and atherosclerosis may not be conclusive, enough circumstantial evidence exists to believe that treating gout will reduce CV risks, he said. “Some of the imaging techniques do suggest that gouty crystals [are] in the atherosclerotic plaque of gout patients,” Dr. Garshick added. Dr. Pillinger’s work, he said, “is showing us that there are different pathways to develop atherosclerosis.”

Dr. Pillinger disclosed relationships with Federation Bio, Fortress Biotech, Amgen, Scilex, Hikma Pharmaceuticals, LG Chem, and Olatec Therapeutics. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

Dr. Pillinger provided more evidence that the understanding of the relationship between gout, gout flares, and CV risk is evolving, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone, New York City.

“There’s epidemiologic evidence supporting the association,” Dr. Garshick told this news organization after the conference. “We think that most conditions with immune system activation do tend to have an increased risk of some form of cardiovascular disease, but I think the relationship with gout has been highly underpublicized.”

Many patients with gout tend to have a higher prevalence of traditional cardiometabolic issues, which may compound the relationship, Dr. Garshick added. “However, I would argue that with this patient subset that it doesn’t matter because gout patients have a higher risk of traditional risk factors, and you have to [treat-to-target] those traditional risk factors.”

While the clinical evidence of a link between gout and atherosclerosis may not be conclusive, enough circumstantial evidence exists to believe that treating gout will reduce CV risks, he said. “Some of the imaging techniques do suggest that gouty crystals [are] in the atherosclerotic plaque of gout patients,” Dr. Garshick added. Dr. Pillinger’s work, he said, “is showing us that there are different pathways to develop atherosclerosis.”

NEW YORK — Urate, the culprit of gout, affects the vasculature in multiple ways that can raise cardiovascular risk (CV) in an individual with gout, and following guidelines for gout treatment, including the use of colchicine, can be the key to reducing those risks.

“Guideline-concordant gout treatment, which is essentially an anti-inflammatory urate-lowering strategy, at least improves arterial physiology and likely reduces cardiovascular risk,” Michael H. Pillinger, MD, told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference. Dr. Pillinger is professor of medicine and biochemistry and molecular pharmacology at New York University Grossman School of Medicine, New York City, who has published multiple studies on gout.

He cited evidence that has shown soluble urate stimulates the production of C-reactive protein (CRP), which is a predictor of cardiovascular disease (CVD). Another study, in which Dr. Pillinger participated, demonstrated that gout patients have impaired vascular endothelial function associated with a chronic, low-level inflammatory state, he said.

“There’s good evidence that urate itself affects the vasculature in multiple ways, and I suspect this may be a model for other metabolic effects on vasculature,” Dr. Pillinger said. “Patients with gout have abnormal endothelium in ways that really convey vascular risk.”
 

Gout, Inflammation, and CVD

However, for rheumatologists to study the association between gout-related inflammation and CVD is “very, very hard,” Dr. Pillinger added. “But I do think that the mechanisms by which gout induces biological changes in the vasculature may provide insights into cardiovascular disease in general.”

One way to evaluate the effects of gout on the endothelium in the clinic is to measure flow-mediated dilation. This technique involves placing an ultrasound probe over the brachial artery and measuring the baseline artery diameter. Then, with the blood pressure cuff over the forearm, inflate it to reduce flow, then release the cuff and measure the brachial artery diameter after the endothelium releases vasodilators.

Dr. Pillinger and colleagues evaluated this technique in 34 patients with gout and 64 controls and found that patients with gout had an almost 50% decrease in flow-mediated dilation, he said. “Interestingly, the higher the urate, the worse the flow; the more the inflammation, the worse the flow, so seemingly corresponding with the severity of the gout,” he said. That raised an obvious question, Dr. Pillinger continued: “If you can treat the gout, can you improve the flow-mediated dilation?”

His group answered that question with a study in 38 previously untreated patients with gout, giving them colchicine 0.6 mg twice daily for a month plus a urate-lowering xanthine oxidase inhibitor (allopurinol or febuxostat) to treat them to a target urate level of < 6 mg/dL. “We saw an increase in endothelial function, and it normalized,” Dr. Pillinger said.

However, some study participants didn’t respond. “They were people with well-established other cardiovascular comorbidities — hypertension, hyperlipidemia,” he said. “I think some people just have vessels that are too damaged to get at them just by fixing their gout problem or their inflammation.”

That means patients with gout need to be treated with colchicine early on to avoid CV problems, Dr. Pillinger added. “We ought to get to them before they have the other problems,” he said.

Managing gout, and the concomitant CV problems, requires vigilance both during and in between flares, Dr. Pillinger said after his presentation.

“We have always taught that patients between flares basically look like people with no gout, but we do know now that patients with gout between flares tend to have what you might call ‘subclinical’ inflammation: CRPs and ESRs [erythrocyte sedimentation rates] that are higher than those of the general population, though not so excessive that they might grab attention,” he said. “We also know that many, if not all, patients between flares have urate deposited in or around their joints, but how these two relate is not fully established.”

Better treatment within 3 months of an acute gout flare may reduce the risk for CV events, he said, but that’s based on speculation more so than clinical data.
 

Potential Benefits of Targeting Inflammation

“More chronically, we know from the cardiologists’ studies that anti-inflammatory therapy should reduce risk in the high-risk general population,” Dr. Pillinger said. “There are no prospective studies confirming that this approach will work among gout patients, but there is no reason why it shouldn’t work — except perhaps that gout patients may have higher inflammation than the general population and also have more comorbidities, so they could perhaps be more resistant.”

Dr. Pillinger said that his group’s studies and another led by Daniel Solomon, MD, at Brigham and Women’s Hospital in Boston, have indicated that anti-inflammatory strategies in gout will lower CV risk.

“And interestingly,” he added, “our data suggest that colchicine use may lower risk not only in high-risk gout patients but also in gout patients who start with no CAD [coronary artery disease] but who seem to have less incident CAD on colchicine. I see this as identifying that gout patients are intrinsically at high risk for CAD, even if they don’t actually have any, so they represent a population for whom lowering chronic inflammation may help prevent incident disease.”

NEW YORK — Patients with rheumatoid arthritis (RA) carry a high risk for cardiovascular events, but mounting clinical evidence suggests they’re being undertreated to manage that risk. Rheumatologists should consider a patient with RA’s cardiovascular disease (CVD) status before deciding on RA treatments, a researcher of cardiometabolic disorders advised.

“The ORAL Surveillance trial suggests that we need to consider cardiovascular risk factors and maybe do additional screening in these patients before we use RA therapies,” Jon T. Giles, MD, PhD, director of the Cedars-Sinai Inflammatory Arthritis Clinical Center at Cedars-Sinai in Los Angeles, told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference.
 

Underuse of Statins

ORAL Surveillance enrolled 4362 patients with RA aged 50 years and older with at least one cardiovascular risk factor. About 23% of all patients were taking statins, as were about half of patients with a history of atherosclerotic CVD (ASCVD).

Giles_Jon_NY_web.jpg

“A lot of those people should have been on statins,” Dr. Giles said in an interview. “Not because of their RA but because of their risk factors, and then RA brings it up another notch.” In the population with ASCVD, Dr. Giles added, “It should have been more like 70% and 80%. If we’re talking about a disease that has enhanced cardiovascular risk, then the adoption of standard care that you would do for anybody in the general population should be at that standard and maybe above.”

Multiple studies have documented the underlying risk for CVD events, CV mortality, and subclinical atherosclerosis in people with RA, Dr. Giles noted in his presentation. Physiologically, the RA-specific risk factors most linked to CVD risk are systemic inflammation/cytokine excess and specific circulating T-cell and intermediate monocyte subsets, or both, Dr. Giles said.
 

Disease-Modifying Antirheumatic Drugs (DMARDs) and CVD Risk

Likewise, research in the past decade has linked methotrexate and tumor necrosis factor (TNF) inhibitors to reduced ASCVD events in RA. Another study showed that abatacept had an effect similar to that of etanercept in patients with RA, and the ENTRACTE trial, for which Dr. Giles was the lead author, demonstrated that tocilizumab matched etanercept in reducing CV events.

The ORAL Surveillance investigators also reported that patients with RA who were receiving the Janus kinase (JAK) inhibitor tofacitinib had a higher risk for major adverse cardiovascular events and cancers than those on TNF therapy, Dr. Giles noted. While statins in combination with JAK inhibitors may have the potential to provide a balance for controlling CV risk in patients with RA, he said later that the potential of JAK inhibitors in reducing CVD risk in RA “is still unsettled.”

The ongoing TARGET trial is further evaluating the impact of DMARDs on vascular inflammation in RA, said Dr. Giles, who’s also a trial principal investigator. TARGET is randomizing 115 patients with RA who didn’t respond to methotrexate to a TNF inhibitor or the addition of sulfasalazine and hydroxychloroquine to their methotrexate. Patients can be on low-intensity but not high-intensity statin therapy, Dr. Giles said.

TARGET results reported last year demonstrated an 8% decrease in arterial fluorodeoxyglucose (FDG) uptake on PET-CT in both treatment arms. Previous studies, Dr. Giles noted, have shown a potential link between FDG and histologic markers of inflammation. “An 8% decrease in vascular FDG is in line with what you would expect from statin treatment,” he said.

TARGET results published in April showed that a measure of a cluster of 12 cytokines and other inflammatory mediators, known as the multibiomarker disease activity (MBDA) score and marketed under the brand name Vectra DA, may help determine arterial FDG uptake. “Those who had a low MBDA score at week 24 actually had the greatest reduction in the arterial FDG,” he said.

Those results were driven entirely by low serum amyloid A (SAA) levels, Dr. Giles said. Those same results didn’t hold for patients in whom SAA and C-reactive protein were correlated.

“So, there’s more to come here,” Dr. Giles said. “We’re looking at other, much larger biomarker panels.”

Nonetheless, he said, sufficient evidence exists to conclude that treating RA to target reduces CV events. “The idea is that at every visit that you see an RA patient, you measure their disease activity, and if they’re not at the target of low disease activity or remission, then you change their therapy to improve that,” he said in an interview.

But an evidence-based guideline is needed to improve coverage of CVD risks in patients with RA, Dr. Giles said. “There is a movement afoot” for a guideline, he said. “If you just did what is supposed to happen for a general population, you would make some improvements. The risk-benefit [ratio] for statins for people with RA has been looked at, and it’s very favorable.”
 

Unanswered Questions

Dr. Giles noted that the ORAL Surveillance trial has left a number of questions unanswered about the role of JAK inhibitors in managing CVD risk in patients with RA. “The issue that we’re trying to ask is, is it just the TNF inhibitors may be better? Is this a subpopulation issue, or was it just bad luck from the purposes of this one trial? Granted, it was a very large trial, but you can still have luck in terms of getting an effect that’s not accurate.”

Dr. Giles’ “gut feeling” on JAK inhibitors is that they’re not causing harm, but that they’re not as effective as TNF inhibitors in ameliorating CV risks in patients with RA.

Michael S. Garshick, MD, who attended the conference and is head of the cardio-rheumatology program at NYU Langone Health, concurred that a number of unanswered questions persist over the treatment of CVD risk in RA — and autoimmune disease in general.

Garshick_Michael_NY_web.JPG

“I think we’re still trying to prove that DMARDs reduce cardiovascular risk in autoimmune conditions,” he said. “The epidemiologic data would suggest, yes, that inflammation prevention is beneficial for cardiovascular disease, but the TARGET trial suggested that vascular inflammation improved by treating RA, but that biologic therapy wasn’t better than traditional triple therapy.”

Other questions remain unanswered, Dr. Garshick said.

“Is there a specific immunotherapy that is most beneficial to reduce heart disease in patients with an autoimmune condition, whether it’s rheumatoid arthritis, psoriasis, or lupus?”

Dr. Garshick said he’s specifically interested in the residual risk that exists after treating the autoimmunity. “Do you still have a higher risk for heart disease, and if so, why? Is there something else going on that we can’t see?”

The biggest unanswered question, he said, is “How can we do a better job of recognizing heart disease risk in these patients? That’s the low-hanging fruit that people are studying, but across many of those studies, patients have higher rates of blood pressure, cholesterol issues, obesity, diabetes, and many times, we’re not adequately treating these comorbidities.”

That, Dr. Garshick said, may be a result of physician fatigue. “And so [treatment of these comorbidities is] kicked down the road for a year or years,” he added.

Dr. Giles disclosed financial relationships with Pfizer, AbbVie, Eli Lilly, and Novartis. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

NEW YORK — Systemic autoimmune disease is well-recognized as a major risk factor for cardiovascular disease (CVD), but less recognized as a cardiovascular risk factor is a history of pregnancy complications, including preeclampsia, and cardiologists and rheumatologists need to include an obstetric history when managing patients with autoimmune diseases, a specialist in reproductive health in rheumatology told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference.

“Autoimmune diseases, lupus in particular, increase the risk for both cardiovascular disease and maternal placental syndromes,” Lisa R. Sammaritano, MD, a professor at Hospital for Special Surgery in New York City and a specialist in reproductive health issues in rheumatology patients, told attendees. “For those patients who have complications during pregnancy, it further increases their already increased risk for later cardiovascular disease.”
 

CVD Risk Double Whammy

A history of systemic lupus erythematosus (SLE) and problematic pregnancy can be a double whammy for CVD risk. Dr. Sammaritano cited a 2022 meta-analysis that showed patients with SLE had a 2.5 times greater risk for stroke and almost three times greater risk for myocardial infarction than people without SLE.

Sammaritano_Lisa_NY_2_web.jpg

Maternal placental syndromes include pregnancy loss, restricted fetal growth, preeclampsia, premature membrane rupture, placental abruption, and intrauterine fetal demise, Dr. Sammaritano said. Hypertensive disorders of pregnancy, formerly called adverse pregnancy outcomes, she noted, include gestational hypertension, preeclampsia, and eclampsia.

Pregnancy complications can have an adverse effect on the mother’s postpartum cardiovascular health, Dr. Sammaritano noted, a fact borne out by the cardiovascular health after maternal placental syndromes population-based retrospective cohort study and a 2007 meta-analysis that found a history of preeclampsia doubles the risk for venous thromboembolism, stroke, and ischemic heart disease up to 15 years after pregnancy.

“It is always important to obtain a reproductive health history from patients with autoimmune diseases,” Dr. Sammaritano told this news organization in an interview. “This is an integral part of any medical history. In the usual setting, this includes not only pregnancy history but also use of contraception in reproductive-aged women. Unplanned pregnancy can lead to adverse outcomes in the setting of active or severe autoimmune disease or when teratogenic medications are used.”

Pregnancy history can be a factor in a woman’s cardiovascular health more than 15 years postpartum, even if a woman is no longer planning a pregnancy or is menopausal. “As such, this history is important in assessing every woman’s risk profile for CVD in addition to usual traditional risk factors,” Dr. Sammaritano said.

“It is even more important for women with autoimmune disorders, who have been shown to have an already increased risk for CVD independent of their pregnancy history, likely related to a chronic inflammatory state and other autoimmune-related factors such as presence of antiphospholipid antibodies [aPL] or use of corticosteroids.”

Timing of disease onset is also an issue, she said. “In patients with SLE, for example, onset of CVD is much earlier than in the general population,” Dr. Sammaritano said. “As a result, these patients should likely be assessed for risk — both traditional and other risk factors — earlier than the general population, especially if an adverse obstetric history is present.”

At the younger end of the age continuum, women with autoimmune disease, including SLE and antiphospholipid syndrome, who are pregnant should be put on guideline-directed low-dose aspirin preeclampsia prophylaxis, Dr. Sammaritano said. “Whether every patient with SLE needs this is still uncertain, but certainly, those with a history of renal disease, hypertension, or aPL antibody clearly do,” she added.

The evidence supporting hydroxychloroquine (HCQ) in these patients is controversial, but Dr. Sammaritano noted two meta-analyses, one in 2022 and the other in 2023, that showed that HCQ lowered the risk for preeclampsia in women.

“The clear benefit of HCQ in preventing maternal disease complications, including flare, means we recommend it regardless for all patients with SLE at baseline and during pregnancy [if tolerated],” Dr. Sammaritano said. “The benefit or optimal use of these medications in other autoimmune diseases is less studied and less certain.”

Dr. Sammaritano added in her presentation, “We really need better therapies and, hopefully, those will be on the way, but I think the takeaway message, particularly for practicing rheumatologists and cardiologists, is to ask the question about obstetric history. Many of us don’t. It doesn’t seem relevant in the moment, but it really is in terms of the patient’s long-term risk for cardiovascular disease.”
 

The Case for Treatment During Pregnancy

Prophylaxis against pregnancy complications in patients with autoimmune disease may be achievable, Taryn Youngstein, MBBS, consultant rheumatologist and codirector of the Centre of Excellence in Vasculitis Research, Imperial College London, London, England, told this news organization after Dr. Sammaritano’s presentation. At the 2023 American College of Rheumatology Annual Meeting, her group reported the safety and effectiveness of continuing tocilizumab in pregnant women with Takayasu arteritis, a large-vessel vasculitis predominantly affecting women of reproductive age.

“What traditionally happens is you would stop the biologic particularly before the third trimester because of safety and concerns that the monoclonal antibody is actively transported across the placenta, which means the baby gets much more concentration of the drug than the mum,” Dr. Youngstein said.

It’s a situation physicians must monitor closely, she said. “The mum is donating their immune system to the baby, but they’re also donating drug.”

“In high-risk patients, we would share decision-making with the patient,” Dr. Youngstein continued. “We have decided it’s too high of a risk for us to stop the drug, so we have been continuing the interleukin-6 [IL-6] inhibitor throughout the entire pregnancy.”

The data from Dr. Youngstein’s group showed that pregnant women with Takayasu arteritis who continued IL-6 inhibition therapy all carried to term with healthy births.

“We’ve shown that it’s relatively safe to do that, but you have to be very careful in monitoring the baby,” she said. This includes not giving the infant any live vaccines at birth because it will have the high levels of IL-6 inhibition, she said.

Dr. Sammaritano and Dr. Youngstein had no relevant financial relationships to disclose.

NEW YORK — Systemic autoimmune disease is well-recognized as a major risk factor for cardiovascular disease (CVD), but less recognized as a cardiovascular risk factor is a history of pregnancy complications, including preeclampsia, and cardiologists and rheumatologists need to include an obstetric history when managing patients with autoimmune diseases, a specialist in reproductive health in rheumatology told attendees at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference.

“Autoimmune diseases, lupus in particular, increase the risk for both cardiovascular disease and maternal placental syndromes,” Lisa R. Sammaritano, MD, a professor at Hospital for Special Surgery in New York City and a specialist in reproductive health issues in rheumatology patients, told attendees. “For those patients who have complications during pregnancy, it further increases their already increased risk for later cardiovascular disease.”
 

CVD Risk Double Whammy

A history of systemic lupus erythematosus (SLE) and problematic pregnancy can be a double whammy for CVD risk. Dr. Sammaritano cited a 2022 meta-analysis that showed patients with SLE had a 2.5 times greater risk for stroke and almost three times greater risk for myocardial infarction than people without SLE.

Sammaritano_Lisa_NY_2_web.jpg

Maternal placental syndromes include pregnancy loss, restricted fetal growth, preeclampsia, premature membrane rupture, placental abruption, and intrauterine fetal demise, Dr. Sammaritano said. Hypertensive disorders of pregnancy, formerly called adverse pregnancy outcomes, she noted, include gestational hypertension, preeclampsia, and eclampsia.

Pregnancy complications can have an adverse effect on the mother’s postpartum cardiovascular health, Dr. Sammaritano noted, a fact borne out by the cardiovascular health after maternal placental syndromes population-based retrospective cohort study and a 2007 meta-analysis that found a history of preeclampsia doubles the risk for venous thromboembolism, stroke, and ischemic heart disease up to 15 years after pregnancy.

“It is always important to obtain a reproductive health history from patients with autoimmune diseases,” Dr. Sammaritano told this news organization in an interview. “This is an integral part of any medical history. In the usual setting, this includes not only pregnancy history but also use of contraception in reproductive-aged women. Unplanned pregnancy can lead to adverse outcomes in the setting of active or severe autoimmune disease or when teratogenic medications are used.”

Pregnancy history can be a factor in a woman’s cardiovascular health more than 15 years postpartum, even if a woman is no longer planning a pregnancy or is menopausal. “As such, this history is important in assessing every woman’s risk profile for CVD in addition to usual traditional risk factors,” Dr. Sammaritano said.

“It is even more important for women with autoimmune disorders, who have been shown to have an already increased risk for CVD independent of their pregnancy history, likely related to a chronic inflammatory state and other autoimmune-related factors such as presence of antiphospholipid antibodies [aPL] or use of corticosteroids.”

Timing of disease onset is also an issue, she said. “In patients with SLE, for example, onset of CVD is much earlier than in the general population,” Dr. Sammaritano said. “As a result, these patients should likely be assessed for risk — both traditional and other risk factors — earlier than the general population, especially if an adverse obstetric history is present.”

At the younger end of the age continuum, women with autoimmune disease, including SLE and antiphospholipid syndrome, who are pregnant should be put on guideline-directed low-dose aspirin preeclampsia prophylaxis, Dr. Sammaritano said. “Whether every patient with SLE needs this is still uncertain, but certainly, those with a history of renal disease, hypertension, or aPL antibody clearly do,” she added.

BALTIMORE — Ice packs or topical anesthesia applied to the face before thermomechanical fractional injury therapy to treat wrinkles around the eyes provided satisfactory comfort to the patient during the procedure without sacrificing posttreatment outcomes, a small study of the recently cleared device found.

The study enrolled 12 patients who were undergoing treatment for periorbital rhytides, or wrinkles, around the eyes. Seven of them received topical anesthetic cream 20 minutes before the procedure, while five were given ice packs to self-apply for 5 minutes beforehand. Patients received four treatment sessions with a month between sessions and were then evaluated up to 3 months after their last session. Study results were presented at the annual conference of the American Society for Laser Medicine and Surgery.

“Based on the approach that we had used, which was to keep the device parameters the same for those who received topical anesthetics and those who received ice, when we looked at the pain levels that the patients had relayed to us when we were doing the procedure, we found that both of them were almost exactly the same in terms of discomfort, a level of 3-4 out of 10, with 10 being the highest discomfort level,” lead investigator Jerome M. Garden, MD, said in an interview after the conference.

“In terms of patient satisfaction using a range of 0-5, again it was fairly equivalent” between the two groups, said Dr. Garden, professor of clinical dermatology and biomedical engineering at Northwestern University, Chicago. “And the overall satisfaction rate was high.”

Garden_Jerome_M_IL2_web.jpg

Study Results

The results for the different anesthetic methods were almost identical. Those using ice reported a 0-10 average pain level of 3.95 ± 1.5, while those who received the topical anesthetic reported a pain level of 3.92 ± 1.5. In terms of self-graded improvement at 3-month follow-up, using a scale of 1-4, with 1 representing up to a 25% improvement and 4 a 75%-100% improvement, the patients using ice had a 2.6 ± 0.5 improvement and those using topical cream a 2.8 ± 0.5 improvement, Dr. Garden said during his presentation.

In terms of patient satisfaction, rated on a scale of 1-5, with 5 being very satisfied, the average grade was 3.9 ± 0.9, Dr. Garden added, with 70% rating ≥ 4.

“This is a relatively new device, which uses an approach to help texture changes in wrinkling on the skin in a different fashion than any of the other devices that are currently out there,” Dr. Garden told this news organization after the conference. “I wanted to understand more in depth the different parameters that may impact the outcome” with this device, he added.

The thermomechanical fractional injury device, originally cleared by the US Food and Drug Administration (FDA) in 2021, with a second-generation device cleared in June 2023, deposits heat into the skin, producing controlled thermal injury to promote collagen and elastin production. The device uses only heat, not a laser, which penetrates the skin. A heat sensation on the skin during the procedure can affect patients differently depending on their level of tolerance, Dr. Garden said during his presentation. 

Managing Patient Discomfort

Kachiu C. Lee, MD, MPH, of the Main Line Center for Laser Surgery in Ardmore, Pennsylvania, has used the device in her own practice and found that “it can definitely get a little bit uncomfortable for patients,” she said in an interview after the conference. 

“I would say that as the doctor, my number one priority is to always make sure my patients are comfortable, especially when treating a sensitive area like the eyes,” added Dr. Lee, who was not involved with the study. “I don’t want them to suddenly jump or move from the discomfort when I have a device right next to their eye. I think that the patient comfort is very important to make sure that we’re managing their discomfort so that the procedure is tolerable.”

NEW YORK — New insights into colchicine’s disruption of the pathway that contributes to arterial inflammation and new clinical studies of the drug could pave the way toward greater use of the anti-inflammatory drug in patients with or at risk for atherosclerotic cardiovascular disease (ASCVD), researchers said at the 4th Annual Cardiometabolic Risk in Inflammatory Conditions conference.

Colchicine was approved by the US Food and Drug Administration (FDA) in June 2023 in a once-daily 0.5-mg formulation under the brand name Lodoco to reduce the risk for major adverse cardiovascular events (MACE) in patients with established atherosclerotic disease or with multiple risk factors for CVD. The Lodoco formulation is slightly smaller than the 0.6-mg formulation that’s taken twice daily for the prophylaxis and treatment of acute gout flares.

In a presentation at the conference, Binita Shah, MD, one of the principal investigators in trials of Lodoco, explained how the inflammatory pathway contributes to atherosclerosis and provided an update on how colchicine disrupts the pathway. Dr. Shah is an associate professor of medicine at New York University in New York City and director of research at NYU Langone Health Interventional Cardiology.

“Colchicine dampens inflammatory markers on neutrophils so that they are less likely to be attracted to inflamed or injured endothelium, which would be the site of where plaque is building up or where the plaque has ruptured in the setting of a heart attack,” Shah told this news organization after her presentation.

Shah_Binita_NY_web.jpg

The Inflammatory Pathway

Dr. Shah explained that normal coronary endothelium resists adhesion by circulating leukocytes, but inflamed or injured coronary endothelium attracts those neutrophils via two types of selectins: L-selectins on neutrophils and E-selectins on endothelial cells. Those neutrophils then release inflammatory cytokines including interleukin-1 beta (IL-1ß), which then triggers production of IL-6 and, subsequently, high-sensitivity C-reactive protein (hsCRP), which contributes to plaque formation, she said.

“Colchicine affects these pathways with a balance for safety and effect on clinical outcomes, particularly to reduce recurrent myocardial infarction [MI],” Dr. Shah said during her presentation. 

Results from the CIRT trial demonstrated that methotrexate is ineffective in blocking the adenosine-mediated anti-inflammatory pathway, Dr. Shah said, so focusing on the IL-1ß–IL-6–hsCRP pathway, which is known to work based on the results of the CANTOS trial, could pay dividends.

“This is where colchicine can potentially play a role,” she said. 

Dr. Shah cited a secondary analysis of the CANTOS trial in which the magnitude of hsCRP reduction correlated with a reduction in MI, stroke, or cardiovascular death. The secondary analysis showed that patients who received canakinumab and achieved hsCRP ≥ 2 mg/L had a nonsignificant 5% lower risk and those who reached < 2 mg/L had a statistically significant 25% lower risk than those who received placebo.

The COPE-PCI Pilot trial demonstrated the benefit of targeting the interleukin pathways, she noted. 

Further clarification of the role of colchicine in managing patients with acute coronary syndrome may come from two other randomized trials now underway, Dr. Shah said: POPCORN is evaluating colchicine to reduce MACE after noncardiac surgery, and CLEAR SYNERGY is evaluating the best timing for colchicine therapy after an acute MI.

Dr. Shah presented preliminary data from her group from a neutrophil biomarker substudy of CLEAR SYNERGY that isolated neutrophils from patients who had an acute MI. “We treated them with various doses of colchicine and showed that the interaction between those treated neutrophils [and] the endothelial cells were a lot lower; they were less sticky to endothelial cells as colchicine was administered,” she said in her presentation. She added that colchicine also reduced neutrophil chemotaxis and neutrophil activation and potentially inhibited inflammasomes, decreasing IL-1ß production.

What’s more, colchicine has been shown to not affect platelets alone but rather platelets at the site of inflammation or plaque rupture, Dr. Shah added. “At currently used doses, colchicine does not inhibit platelet activity [by] itself, so we’ve never seen increased bleeding events, but it will dampen neutrophils’ ability to latch onto a platelet that could contribute to a clot,” she later told this news organization.

“There are multiple studies, both retrospective studies in gout cohorts as well as prospective studies in the cardiovascular cohort, that all show consistently one thing, which is that colchicine continues to reduce the risk of having a recurrent MI in patients who either have cardiovascular disease or are at high risk of having cardiovascular disease,” she said.

“I think that’s very helpful to know that it’s not just one study — it’s not just a fluke, potentially a play of chance — but multiple studies consistently showing the same thing: That there’s a reduced risk of acute MI.”
 

Slow to Embrace Colchicine

Despite this evidence, cardiologists and rheumatologists have been slow to embrace colchicine for patients at risk for cardiovascular events, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone. “What [Shah] really highlighted was that for a number of years now, we’ve had several clinical trials showing the benefit of low-dose colchicine to prevent atherosclerotic cardiovascular events, and yet despite these and that there’s now an indication to use low-dose colchicine to reduce cardiovascular disease, we’re still struggling for this medication to be taken up by the general cardiology community to treat high-risk patients.

“There’s still some work to do to prove that we need to break those barriers,” Dr. Garshick added. Some of the confusion surrounding the use of colchicine for ASCVD may be attributed to the 0.5-mg dose approved for CVD as opposed to the long-approved 0.6-mg dose for gout, he said. “People are generally confused: Is it OK to use the 0.6-mg dose?” Dr. Garshick said.

Potential gastrointestinal side effects may be another concerning factor, although, he added, “we didn’t see any major complications.” Another issue could be polypharmacy in many of these patients, he said.

Dr. Garshick concurred with Shah that the existing evidence supporting the use of colchicine to reduce risk for cardiovascular events is strong, but more will come out. “I think there’s going to be evolving data supporting it,” he said.

Dr. Shah disclosed financial relationships with Philips Volcano and Novo Nordisk. She is a principal investigator of the CLEAR SYNERGY biomarker substudy and the POPCORN trial. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

Colchicine was approved by the US Food and Drug Administration (FDA) in June 2023 in a once-daily 0.5-mg formulation under the brand name Lodoco to reduce the risk for major adverse cardiovascular events (MACE) in patients with established atherosclerotic disease or with multiple risk factors for CVD. The Lodoco formulation is slightly smaller than the 0.6-mg formulation that’s taken twice daily for the prophylaxis and treatment of acute gout flares.

In a presentation at the conference, Binita Shah, MD, one of the principal investigators in trials of Lodoco, explained how the inflammatory pathway contributes to atherosclerosis and provided an update on how colchicine disrupts the pathway. Dr. Shah is an associate professor of medicine at New York University in New York City and director of research at NYU Langone Health Interventional Cardiology.

“Colchicine dampens inflammatory markers on neutrophils so that they are less likely to be attracted to inflamed or injured endothelium, which would be the site of where plaque is building up or where the plaque has ruptured in the setting of a heart attack,” Shah told this news organization after her presentation.

The Inflammatory Pathway

Dr. Shah explained that normal coronary endothelium resists adhesion by circulating leukocytes, but inflamed or injured coronary endothelium attracts those neutrophils via two types of selectins: L-selectins on neutrophils and E-selectins on endothelial cells. Those neutrophils then release inflammatory cytokines including interleukin-1 beta (IL-1ß), which then triggers production of IL-6 and, subsequently, high-sensitivity C-reactive protein (hsCRP), which contributes to plaque formation, she said.

“Colchicine affects these pathways with a balance for safety and effect on clinical outcomes, particularly to reduce recurrent myocardial infarction [MI],” Dr. Shah said during her presentation. 

Results from the CIRT trial demonstrated that methotrexate is ineffective in blocking the adenosine-mediated anti-inflammatory pathway, Dr. Shah said, so focusing on the IL-1ß–IL-6–hsCRP pathway, which is known to work based on the results of the CANTOS trial, could pay dividends.

“This is where colchicine can potentially play a role,” she said. 

Dr. Shah cited a secondary analysis of the CANTOS trial in which the magnitude of hsCRP reduction correlated with a reduction in MI, stroke, or cardiovascular death. The secondary analysis showed that patients who received canakinumab and achieved hsCRP ≥ 2 mg/L had a nonsignificant 5% lower risk and those who reached < 2 mg/L had a statistically significant 25% lower risk than those who received placebo.

The COPE-PCI Pilot trial demonstrated the benefit of targeting the interleukin pathways, she noted. 

Further clarification of the role of colchicine in managing patients with acute coronary syndrome may come from two other randomized trials now underway, Dr. Shah said: POPCORN is evaluating colchicine to reduce MACE after noncardiac surgery, and CLEAR SYNERGY is evaluating the best timing for colchicine therapy after an acute MI.

Dr. Shah presented preliminary data from her group from a neutrophil biomarker substudy of CLEAR SYNERGY that isolated neutrophils from patients who had an acute MI. “We treated them with various doses of colchicine and showed that the interaction between those treated neutrophils [and] the endothelial cells were a lot lower; they were less sticky to endothelial cells as colchicine was administered,” she said in her presentation. She added that colchicine also reduced neutrophil chemotaxis and neutrophil activation and potentially inhibited inflammasomes, decreasing IL-1ß production.

What’s more, colchicine has been shown to not affect platelets alone but rather platelets at the site of inflammation or plaque rupture, Dr. Shah added. “At currently used doses, colchicine does not inhibit platelet activity [by] itself, so we’ve never seen increased bleeding events, but it will dampen neutrophils’ ability to latch onto a platelet that could contribute to a clot,” she later told this news organization.

“There are multiple studies, both retrospective studies in gout cohorts as well as prospective studies in the cardiovascular cohort, that all show consistently one thing, which is that colchicine continues to reduce the risk of having a recurrent MI in patients who either have cardiovascular disease or are at high risk of having cardiovascular disease,” she said.

“I think that’s very helpful to know that it’s not just one study — it’s not just a fluke, potentially a play of chance — but multiple studies consistently showing the same thing: That there’s a reduced risk of acute MI.”
 

Slow to Embrace Colchicine

Despite this evidence, cardiologists and rheumatologists have been slow to embrace colchicine for patients at risk for cardiovascular events, said Michael S. Garshick, MD, who attended the conference and is head of the Cardio-Rheumatology Program at NYU Langone. “What [Shah] really highlighted was that for a number of years now, we’ve had several clinical trials showing the benefit of low-dose colchicine to prevent atherosclerotic cardiovascular events, and yet despite these and that there’s now an indication to use low-dose colchicine to reduce cardiovascular disease, we’re still struggling for this medication to be taken up by the general cardiology community to treat high-risk patients.

“There’s still some work to do to prove that we need to break those barriers,” Dr. Garshick added. Some of the confusion surrounding the use of colchicine for ASCVD may be attributed to the 0.5-mg dose approved for CVD as opposed to the long-approved 0.6-mg dose for gout, he said. “People are generally confused: Is it OK to use the 0.6-mg dose?” Dr. Garshick said.

Potential gastrointestinal side effects may be another concerning factor, although, he added, “we didn’t see any major complications.” Another issue could be polypharmacy in many of these patients, he said.

Dr. Garshick concurred with Shah that the existing evidence supporting the use of colchicine to reduce risk for cardiovascular events is strong, but more will come out. “I think there’s going to be evolving data supporting it,” he said.

Dr. Shah disclosed financial relationships with Philips Volcano and Novo Nordisk. She is a principal investigator of the CLEAR SYNERGY biomarker substudy and the POPCORN trial. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.

BALTIMORE — A 2910-nm erbium-doped fluoride glass fiber laser, approved 2 years ago by the US Food and Drug Administration (FDA), has demonstrated a high degree of improvement for facial photoaging and rhytides along with relatively high rates of patient satisfaction — while causing less discomfort and downtime compared with conventional fractional lasers, a small single-center study showed.

The study enrolled 15 patients who had three treatment sessions with the 2910-nm laser. “It’s highly customizable,” the study’s lead author, Taryn Murray, MD, a dermatologist at Cleveland Clinic, told this news organization. “It has a really fast time in healing compared to traditional abatable lasers; the healing time is 5-7 days vs several weeks.” Dr. Murray presented the results at the annual meeting of the American Society for Laser Medicine and Surgery (ASLMS).
 

The Technology Behind the Laser

The 2910-nm erbium-doped fluoride glass fiber laser is a mid-infrared ablative fractional device that operates at peak water absorption. It’s designed to cause minimal residual thermal damage, resulting in less discomfort, shorter downtime, and potentially fewer side effects than conventional ablative lasers, Dr. Murray said.

Because of the way the pulses are delivered, “it’s far less painful than traditional fractional ablative lasers, so you can use mainly topical numbing; you don’t need nerve blocks, you don’t have to infiltrate lidocaine, you don’t have to put the patient under anesthesia,” she said.

“Because of the wavelength, how pulses are delivered and how customizable the settings are, it’s safer to use in darker skin types,” and the density, depth, and the amount of coagulation applied into the skin are customizable, Dr. Murray added. 

The laser also delivers pulses in a different way than the conventional 2940-nm erbium and CO₂ lasers, she explained. “Traditional lasers do it all in one pulse. This laser uses micropulses with relaxation time in between pulses, so the body interprets it as less painful and allows pressure and steam to escape out of the channel, which results in faster healing.”

[embed:render:related:node:265602]

The study patients had topical anesthetic cream applied to their faces 45-60 minutes before the procedure. Multiple passes were made using both superficial and deep laser modes. The average patient age was 65.7 years, and Fitzpatrick skin types included I (n = 3), II (n = 3), III (n = 7), and IV (n = 2). On a scale of 0-10, the average level of discomfort was 4.9, and the average patient satisfaction after three treatments was 4.8, Dr. Murray said.

For cosmetic improvement, the study used the 5-point Global Aesthetic Improvement Scale (GAIS). Blinded reviewers evaluated digital images and determined an average GAIS score of 3.2 for overall appearance, 2.9 for wrinkles, 3.6 for pigment, 3.1 for skin texture, and 2.6 for skin laxity. 

When the patients themselves reviewed the digital images, the average GAIS score was 3.8 for overall appearance. 

Side effects, said Dr. Murray, were transient, with edema and soft-tissue crusting lasting 3-5 days and erythema resolving in 1-2 weeks on average. One case of postinflammatory hyperpigmentation (PIH) did arise, which was linked to allergic contact dermatitis from the healing ointment. That patient stayed in the study and had complete resolution of the PIH.

Study Stands Out

A number of studies of the 2910-nm erbium-doped fluoride glass fiber laser have emerged over the past half year, Ritu Swali, MD, who was an American Society of Dermatologic Surgery fellow at a practice in Houston, said in an interview at the meeting. But this one stands out because of the evidence surrounding its use.

Most people are using this laser for facial resurfacing, “and we want to know that we have a technology ... with shorter downtime and easier wound care and just more comfort,” she said.
