TOPLINE:

Compared with placebo, administration of vocacapsaicin during bunionectomy reduces pain and decreases opioid consumption in the first 96 hours after surgery, with no local or systemic toxicity.

METHODOLOGY:

• This triple-blind, randomized, placebo-controlled trial included 147 patients undergoing bunionectomy.
• Patients were randomly assigned to receive 14 mL of either 0.05 mg/mL vocacapsaicin, 0.15 mg/mL vocacapsaicin, 0.30 mg/mL vocacapsaicin, or placebo at the surgical site during wound closure. Except for the study drug, all patients received identical perioperative analgesics.
• Patients were observed for 96 hours post-surgery, with follow-up visits on days 8, 15, and 29 to monitor for pain and adverse events.
• The primary endpoint was overall levels of pain at rest through the first 96 hours after surgery for the 0.30-mg/mL vocacapsaicin group.
• The secondary endpoints included the percentage of patients who did not require opioids and total opioid consumption through 96 hours, as well as pain scores during the first postoperative week.

TAKEAWAY:

• Vocacapsaicin (0.30 mg/mL) reduced pain at rest by 33% over the first 96 hours, compared with placebo (P = .005).
• Overall, 26% of patients who received the 0.30-mg/mL dose of vocacapsaicin did not require opioids through 96 hours compared with 5% of patients receiving placebo (P = .025).
• The researchers reported no difference in the rate, type, or severity of adverse events in the four study groups, consistent with typical recovery from bunionectomy.

IN PRACTICE:

“These data suggest that intraoperative administration of vocacapsaicin may provide substantial benefits in other surgical procedures,” the authors wrote.

SOURCE:

The study was led by Steven L. Shafer, MD, of the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University in Stanford, California, and published in the June 2024 issue of Anesthesiology.

LIMITATIONS:

The use of opioids was restricted from 0 to 96 hours after surgery, which did not reflect typical clinical practice. The range of vocacapsaicin concentrations tested may not have been extensive enough, as concentrations > 0.30 mg/mL might have provided better analgesia.

DISCLOSURES:

The study was supported by Concentric Analgesics. Two authors declared being employed by Concentric Analgesics. Other authors declared having several ties with many sources, including the funding agency.

The photo of the patient’s foot, sent from his campsite, included a cheeky note: “I remember you telling me that getting in trouble doing something was better than getting in trouble doing nothing. This lets me get out there and know that I have feedback.”

The “this” was the patient’s “foot selfie,” an approach that allows patients at a risk for diabetic foot ulcers (DFUs) to snap a picture and send it to their healthcare providers for evaluation.

This particular patient had an extensive history of previous wounds. Some had essentially kept him house-bound in the past, as he was afraid to get another one.

This time, however, he got an all-clear to keep on camping, “and we scheduled him in on the following Tuesday [for follow-up],” said the camper’s physician David G. Armstrong, DPM, MD, PhD, professor of surgery and neurological surgery, USC Keck School of Medicine, Los Angeles.

Dr. Armstrong is one of the researchers evaluating the concept of foot selfies. It’s a welcome advance, he and others said, and has been shown to help heal wounds and reverse pre-ulcer lesions. Research on foot selfies continues, but much more is needed to solve the issue of DFUs, diabetic foot infections (DFIs), and the high rates of reinfection, experts know.

Worldwide, about 18.6 million people have a DFU each year, including 1.6 million in the United States. About 50%-60% of ulcers become infected, with 20% of moderate to severe infections requiring amputation of the limb. The 5-year mortality rate for DFUs is 30%, but it climbs to 70% after amputation. While about 40% of ulcers heal within 12 weeks, 42% recur at the 1-year mark, setting up a vicious and costly cycle. Healthcare costs for patients with diabetes and DFUs are five times as high as costs for patients with diabetes but no DFUs. The per capita cost to treat a DFU in America is $17,500.

While the statistics paint a grim picture, progress is being made on several fronts:

• US Food and Drug Administration (FDA) guidance on the development of drugs for DFUs, under evaluation, is forthcoming.
• New treatments are under study.
• A multidisciplinary team approach is known to improve outcomes.

Anatomy of a DFU

When neuropathy develops in those with diabetes, they no longer have what Dr. Armstrong calls the “gift” of pain perception. “They can wear a hole in their foot like you and I wear a hole in our sock or shoe,” he said. “That hole is called a diabetic foot ulcer.”

A DFU is an open wound on the foot, often occurring when bleeding develops beneath a callus and then the callus wears away. Deeper tissues of the foot are then exposed.

About half of the DFUs get infected, hence the FDA guidance, said Dr. Armstrong, who is also founding president of the American Limb Preservation Society, which aims to eliminate preventable amputations within the next generation. Every 20 seconds, Dr. Armstrong said, someone in the world loses a leg due to diabetes.
 

FDA Guidance on Drug Development for DFIs

In October, the FDA issued draft guidance for industry to articulate the design of clinical trials for developing antibacterial drugs to treat DFIs without concomitant bone and joint involvement. Comments closed on December 18. Among the points in the guidance, which is nonbinding, are to include DFIs of varying depths and extent in phase 3 trials and ideally to include only those patients who have not had prior antibacterial treatment for the current DFI.

According to an FDA spokesperson, “The agency is working to finalize the guidance. However, a timeline for its release has not yet been established.”

The good news about the upcoming FDA guidance, Dr. Armstrong said, is that the agency has realized the importance of treating the infections. Fully one third of direct costs of care for diabetes are spent on the lower extremities, he said. Keeping patients out of the hospital, uninfected, and “keeping legs on bodies” are all important goals, he said.

Pharmaceutical firms need to understand that “you aren’t dealing with a normal ulcer,” said Andrew J.M. Boulton, MD, professor of medicine at the University of Manchester and physician consultant at the Manchester Royal Infirmary, Manchester, England, and a visiting professor at the University of Miami. For research, “the most important thing is to take account of off-loading the ulcers,” he said. “Most ulcers will heal if put in a boot.”

Dr. Boulton, like Dr. Armstrong, a long-time expert in the field, contended that pharma has not understood this concept and has wasted millions over the last three decades doing studies that were poorly designed and controlled.
 

Treatments: Current, Under Study

Currently, DFIs are treated with antimicrobial therapy, without or without debridement, along with a clinical assessment for ischemia. If ischemia is found, care progresses to wound care and off-loading devices, such as healing sandals. Clinicians then assess the likelihood of improved outcomes with revascularization based on operative risks and distribution of lower extremity artery disease and proceed depending on the likelihood. If osteomyelitis testing shows it is present, providers proceed to wound debridement, limb-sparing amputation, and prolonged antimicrobials, as needed.

More options are needed, Dr. Armstrong said.

Among the many approaches under study:

• DFUs can be accurately detected by applying artificial intelligence to the “foot selfie” images taken by patients on smartphones, research by Dr.  and  has found.
• After a phase 3 study of  for DFUs originally intending to enroll 300 subjects was discontinued because of slow patient recruitment, an interim analysis was conducted on 44 participants. It showed a positive trend toward wound closure in the group receiving the injected gene therapy, VM202 (ENGENSIS), in their calf muscles. VM202 is a plasmid DNA-encoding human hepatocyte growth factor. While those in both the intervention and placebo groups showed wound-closing effects at month 6, in 23 patients with neuro-ischemic ulcers, the percentage of those reaching complete closure of the DFU was significantly higher in the treated group at months 3, 4, and 5 (P = .0391, .0391, and .0361, respectively). After excluding two outliers, the difference in months 3-6 became more significant (P = .03).
• An closed more DFUs than standard care after 12 weeks — 70% vs 34% (P = .00032). Of the 100 participants randomized, 50 per group, 42% of the treatment group and 56% of the control group experienced adverse events, with eight withdrawn due to serious adverse events (such as osteomyelitis).
• A closed more refractory DFUs over a 16-week study than standard sharp debridement, with 65% of water-treated ulcers healed but just 42% of the standard care group (P = .021, unadjusted).
• Researchers from UC Davis and VA Northern California Healthcare are evaluating timolol, a beta adrenergic receptor blocker already approved for topical administration for glaucoma, as a way to heal chronic DFUs faster. After demonstrating that the medication worked in animal models, researchers then launched a study to use it off-label for DFUs. While data are still being analyzed, researcher Roslyn (Rivkah) Isseroff, MD, of UC Davis and VA, said that data so far demonstrate that the timolol reduced transepidermal water loss in the healed wounds, and that is linked with a decrease in re-ulceration.

The Power of a Team

Multidisciplinary approaches to treatment are effective in reducing amputation, with one review of 33 studies finding the approach worked to decrease amputation in 94% of them. “The American Limb Preservation Society (ALPS) lists 30 programs,” said Dr. Armstrong, the founding president of the organization. “There may be as many as 100.”

Team compositions vary but usually include at least one medical specialty clinician, such as infectious disease, primary care, or endocrinology, and two or more specialty clinicians, such as vascular, podiatric, orthopedic, or plastic surgery. A shoe specialist is needed to prescribe and manage footwear. Other important team members include nutrition experts and behavioral health professionals to deal with associated depression.

Johns Hopkins’ Multidisciplinary Diabetic Foot and Wound Service launched in 2012 and includes vascular surgeons, surgical podiatrists, endocrinologists, wound care nurses, advanced practice staff, board-certified wound care specialists, orthopedic surgeons, infection disease experts, physical therapists, and certified orthotists.

“This interdisciplinary care model has been repeatedly validated by research as superior for limb salvage and wound healing,” said Nestoras Mathioudakis, MD, codirector of the service. “For instance, endocrinologists and diabetes educators are crucial for managing uncontrolled diabetes — a key factor in infection and delayed wound healing. Similarly, vascular surgeons play a vital role in addressing peripheral arterial disease to improve blood flow to the affected area.”

“Diabetic foot ulcers might require prolonged periods of specialized care, including meticulous wound management and off-loading, overseen by surgical podiatrists and wound care experts,” he said. “In cases where infection is present, particularly with multidrug resistant organisms or when standard antibiotics are contraindicated, the insight of an infectious disease specialist is invaluable.”

While the makeup of teams varies from location to location, he said “the hallmark of effective teams is their ability to comprehensively manage glycemic control, foot wounds, vascular disease, and infections.”

The power of teams, Dr. Armstrong said, is very much evident after his weekly “foot selfie rounds” conducted Mondays at 7 AM, with an “all feet on deck” approach. “Not a week goes by when we don’t stop a hospitalization,” he said of the team evaluating the photos, due to detecting issues early, while still in the manageable state.

Teams can trump technology, Dr. Armstrong said. A team of just a primary care doctor and a podiatrist can make a significant reduction in amputations, he said, just by a “Knock your socks off” approach. He reminds primary care doctors that observing the feet of their patients with diabetes can go a long way to reducing DFUs and the hospitalizations and amputations that can result.

Dr. Mathioudakis and Dr. Isseroff reported no disclosures. Dr. Boulton consults for Urgo Medical, Nevro Corporation, and AOT, Inc. Dr. Armstrong reported receiving consulting fees from Podimetrics; Molnlycke; Cardiovascular Systems, Inc.; Endo Pharmaceuticals; and Averitas Pharma (GRT US).

While those in both the intervention and placebo groups showed wound-closing effects at month 6, in 23 patients with neuro-ischemic ulcers, the percentage of those reaching complete closure of the DFU was significantly higher in the treated group at months 3, 4, and 5 (P = .0391, .0391, and .0361, respectively). After excluding two outliers, the difference in months 3-6 became more significant (P = .03).
• An closed more DFUs than standard care after 12 weeks — 70% vs 34% (P = .00032). Of the 100 participants randomized, 50 per group, 42% of the treatment group and 56% of the control group experienced adverse events, with eight withdrawn due to serious adverse events (such as osteomyelitis).
• A closed more refractory DFUs over a 16-week study than standard sharp debridement, with 65% of water-treated ulcers healed but just 42% of the standard care group (P = .021, unadjusted).
• Researchers from UC Davis and VA Northern California Healthcare are evaluating timolol, a beta adrenergic receptor blocker already approved for topical administration for glaucoma, as a way to heal chronic DFUs faster. After demonstrating that the medication worked in animal models, researchers then launched a study to use it off-label for DFUs. While data are still being analyzed, researcher Roslyn (Rivkah) Isseroff, MD, of UC Davis and VA, said that data so far demonstrate that the timolol reduced transepidermal water loss in the healed wounds, and that is linked with a decrease in re-ulceration.

The Power of a Team

Multidisciplinary approaches to treatment are effective in reducing amputation, with one review of 33 studies finding the approach worked to decrease amputation in 94% of them. “The American Limb Preservation Society (ALPS) lists 30 programs,” said Dr. Armstrong, the founding president of the organization. “There may be as many as 100.”

Team compositions vary but usually include at least one medical specialty clinician, such as infectious disease, primary care, or endocrinology, and two or more specialty clinicians, such as vascular, podiatric, orthopedic, or plastic surgery. A shoe specialist is needed to prescribe and manage footwear. Other important team members include nutrition experts and behavioral health professionals to deal with associated depression.

Johns Hopkins’ Multidisciplinary Diabetic Foot and Wound Service launched in 2012 and includes vascular surgeons, surgical podiatrists, endocrinologists, wound care nurses, advanced practice staff, board-certified wound care specialists, orthopedic surgeons, infection disease experts, physical therapists, and certified orthotists.

“This interdisciplinary care model has been repeatedly validated by research as superior for limb salvage and wound healing,” said Nestoras Mathioudakis, MD, codirector of the service. “For instance, endocrinologists and diabetes educators are crucial for managing uncontrolled diabetes — a key factor in infection and delayed wound healing. Similarly, vascular surgeons play a vital role in addressing peripheral arterial disease to improve blood flow to the affected area.”

“Diabetic foot ulcers might require prolonged periods of specialized care, including meticulous wound management and off-loading, overseen by surgical podiatrists and wound care experts,” he said. “In cases where infection is present, particularly with multidrug resistant organisms or when standard antibiotics are contraindicated, the insight of an infectious disease specialist is invaluable.”

While the makeup of teams varies from location to location, he said “the hallmark of effective teams is their ability to comprehensively manage glycemic control, foot wounds, vascular disease, and infections.”

The power of teams, Dr. Armstrong said, is very much evident after his weekly “foot selfie rounds” conducted Mondays at 7 AM, with an “all feet on deck” approach. “Not a week goes by when we don’t stop a hospitalization,” he said of the team evaluating the photos, due to detecting issues early, while still in the manageable state.

Teams can trump technology, Dr. Armstrong said. A team of just a primary care doctor and a podiatrist can make a significant reduction in amputations, he said, just by a “Knock your socks off” approach. He reminds primary care doctors that observing the feet of their patients with diabetes can go a long way to reducing DFUs and the hospitalizations and amputations that can result.

Dr. Mathioudakis and Dr. Isseroff reported no disclosures. Dr. Boulton consults for Urgo Medical, Nevro Corporation, and AOT, Inc. Dr. Armstrong reported receiving consulting fees from Podimetrics; Molnlycke; Cardiovascular Systems, Inc.; Endo Pharmaceuticals; and Averitas Pharma (GRT US).

“Fingers, toes, ears, and nose are places where epinephrine never goes,” Thomas Ehlers, DPM, wrote in Podiatry Today. “That is an adage I heard during podiatry school, my clerkships, and from various attendings throughout my training.”

But as Dr. Ehlers added, epinephrine gets a bad rap. The catchy admonition “has been proven a myth time and time again.”

So why do many clinicians believe the combination of epinephrine and lidocaine to be off-limits in surgical interventions involving the digits and other regions with low blood flow? Although medical trainees across multiple disciplines are taught to fear the practice, citing the potential for gangrene, its reputation for harm is not supported by the evidence.
 

Lack of Feeling Doesn’t Care About Your Facts

The debate surfaced anew in response to a recent column by Kenny Lin, MD, MPH, family physician and associate director of the Lancaster General Hospital Family Medicine Residency, in Lancaster, Pennsylvania, about the rather pedestrian topic of why he no longer performs surgery to correct ingrown toenails. Dr. Lin’s admission that he used to do the procedure with a combination of epinephrine and lidocaine turned into a major focus of the comments — many of them harshly critical of the practice:

“Epinephrine is not an appropriate drug to use for podiatry or use in any peripheral area. Gangrene?” one commenter posted.

“Leave epi out of lidocaine to fingers, toes, nose, and ear lobes,” another wrote.

“No lido with epi, whether or not it is contraindicated, because: If there’s any adverse outcome, a lawyer will find plenty of references saying it was contraindicated,” a reader chimed in.

Other commenters disagreed, with one saying, “Please, folks, don’t show that you trained 50 years ago and haven’t changed practice since…”

For Dr. Lin, the response was surprising given what he believes to be the lack of evidence supporting the purported dangers.

“When I think about this, it’s something that was taught to me during residency — that they should not be used on certain areas,” Dr. Lin said. “But since then, studies have been published looking at thousands of cases of people using epinephrine with lidocaine and haven’t found any cases of necrosis.”

Many doctors, like Dr. Lin, say they were cautioned against this in their training. Others don’t remember exactly where they’ve heard it but recognize the idea has a nebulous hold on practice.

Combining epinephrine with lidocaine helps make the numbing last longer, stops bleeding, and reduces the use of lidocaine required, all of which improve the chances of an effective and comfortable intervention for the patient, Dr. Lin said. The approach also reduces the use of tourniquets, which come with their own risks including nerve injury.

However, in areas with limited circulation, this vasoconstrictive effect may be more pronounced, potentially leading to complications for patients with complicating factors.

Clinicians who regularly use the combination of epinephrine and lidocaine for surgery do concede that it can pose certain hazards and considerations in areas without robust blood flow.

But the literature largely points to its safety.

In 2001, California-based plastic and reconstructive surgeon Keith Denkler, MD, published a deep dive on the topic starting in the 19th century, including a review of Index Medicus from 1880 to 1966, a computer review of the National Library of Medicine database from 1966 to 2000, and major textbooks from 1900 to 2000.

He found a total of 48 cases of digital gangrene — but most involved the use of cocaine or procaine. Of the 48 cases, 21 involved the use of epinephrine, and 17 used an unknown concentration based on manual dilution.

“Multiple other concurrent conditions (hot soaks, tight tourniquets, and infection) existed in these case reports, making it difficult to determine the exact cause of the tissue insult,” Dr. Denkler wrote.

In a 2010 retrospective review in the Journal of the American Society of Plastic Surgeons, authors examined 1111 cases involving digital and hand surgery. Of the 611 patients who received injections of 1% lidocaine with epinephrine, none experienced digital necrosis.

Another review from 2003 touted the combination’s safety, in hopes to “help dispel the myth that epinephrine has no place in podiatric anesthesia.” But authors noted limitations of use, including “known sensitivity, thyrotoxicosis, and use of either tricyclic antidepressants or monoamine oxidase inhibitors.”

James Christina, DPM, executive director and CEO of the American Podiatric Medical Association, echoed that sentiment. He said he regularly used the combination to correct bunions, hammer toes, and ingrown toenails over his 20 years of practicing but acknowledged the technique is not appropriate for all such patients.

“There’s always been caution when using epinephrine with local anesthetic,” Dr. Christina told this news organization. “You need a healthy patient with normal circulation and no other complications; someone without vascular compromise.”

Marie Hanna, MD, MEHP, chief of regional anesthesia and acute pain management at Johns Hopkins University, Baltimore, counts herself among the cautious. Citing Principles of Office Anesthesia: Part I. Infiltrative Anesthesia, Dr. Hanna said epinephrine should never be used in digital and penile blocks or in skin flaps with marginal viability.

“It is perfectly fine in certain areas, like the wrist or the arm,” Dr. Hanna said. “But specifically for use in end organs like nose, fingers, ears, toes — all of these with tenuous blood supply — it is not good practice.”

The divide among doctors comes down to theoretical concern, rather than empirical basis, said Rebecca Johnson, MD, chair of the American Society of Anesthesiologists committee on Regional Anesthesia and Acute Pain Medicine and a faculty member at Mayo Clinic, in Rochester, Minnesota.

“It’s just one of those myths we have in practice,” she said.

And legally, Dr. Johnson noted, the mere existence of a myth can be enough of a deterrent for medical practitioners: “Like anything, when you’re trying to do the right thing, if a complication would occur for another reason, you’d want to make sure a jury of your peers didn’t bring up that myth.”

High school students are injuring themselves more severely even as overall injury rates have declined, according to a new study presented at the annual meeting of the American Academy of Orthopaedic Surgeons.

The study compared injuries from a 4-year period ending in 2019 to data from 2005 and 2006. The overall rate of injuries dropped 9%, from 2.51 injuries per 1,000 athletic games or practices to 2.29 per 1,000; injuries requiring less than 1 week of recovery time fell by 13%. But, the number of head and neck injuries increased by 10%, injuries requiring surgery increased by 1%, and injuries leading to medical disqualification jumped by 11%. 

“It’s wonderful that the injury rate is declining,” said Jordan Neoma Pizzarro, a medical student at George Washington University, Washington, who led the study. “But the data does suggest that the injuries that are happening are worse.”

The increases may also reflect increased education and awareness of how to detect concussions and other injuries that need medical attention, said Micah Lissy, MD, MS, an orthopedic surgeon specializing in sports medicine at Michigan State University, East Lansing. Dr. Lissy cautioned against physicians and others taking the data at face value. 

“We need to be implementing preventive measures wherever possible, but I think we can also consider that there may be some confounding factors in the data,” Dr. Lissy told this news organization. 

Ms. Pizzarro and her team analyzed data collected from athletic trainers at 100 high schools across the country for the ongoing National Health School Sports-Related Injury Surveillance Study.

Athletes participating in sports such as football, soccer, basketball, volleyball, and softball were included in the analysis. Trainers report the number of injuries for every competition and practice, also known as “athletic exposures.”

Boys’ football carried the highest injury rate, with 3.96 injuries per 1,000 AEs, amounting to 44% of all injuries reported. Girls’ soccer and boys’ wrestling followed, with injury rates of 2.65 and 1.56, respectively. 

Sprains and strains accounted for 37% of injuries, followed by concussions (21.6%). The head and/or face was the most injured body site, followed by the ankles and/or knees. Most injuries took place during competitions rather than in practices (relative risk, 3.39; 95% confidence interval, 3.28-3.49; P < .05).

Ms. Pizzarro said that an overall increase in intensity, physical contact, and collisions may account for the spike in more severe injuries.

“Kids are encouraged to specialize in one sport early on and stick with it year-round,” she said. “They’re probably becoming more agile and better athletes, but they’re probably also getting more competitive.” 

Dr. Lissy, who has worked with high school athletes as a surgeon, physical therapist, athletic trainer, and coach, said that some of the increases in severity of injuries may reflect trends in sports over the past two decades: Student athletes have become stronger and faster and have put on more muscle mass. 

“When you have something that’s much larger, moving much faster and with more force, you’re going to have more force when you bump into things,” he said. “This can lead to more significant injuries.”

The study was independently supported. Study authors report no relevant financial relationships.

Adults who underwent either total ankle replacement or ankle fusion for end-stage ankle osteoarthritis showed similar clinical scores and adverse event numbers, in a randomized controlled trial of approximately 300 patients.

Ankle osteoarthritis remains a cause of severe pain and disability. Patients are treated nonoperatively if possible, but surgery is often needed for individuals with end-stage disease, wrote Andrew Goldberg, MBBS, of University College London and colleagues in the Annals of Internal Medicine.

“Most patients with ankle arthritis respond to nonoperative treatments, such as weight loss, activity modification, support braces, and analgesia, [but] once the disease has progressed to end-stage osteoarthritis, the main surgical treatments are total ankle re-placement or ankle arthrodesis,” Dr. Goldberg said, in an interview.

In the new study, patients were randomized to receive either a total ankle replacement (TAR) or ankle fusion (AF).

“We showed that, in both treatment groups the clinical scores improved hugely, by more than three times the minimal clinically important difference,” Dr. Goldberg said in an interview.

“Although the ankle replacement arm improved, on average, by more than an extra 4 points over ankle fusion, this was not considered clinically or statistically significant,” he said.

The study is the first randomized trial to show high-quality and robust results, he noted, and findings support data from previous studies.

“Although both TAR and ankle fusion have been shown to be effective, they are very different treatments, with one fusing the bones so that there is no ankle joint movement, and the other replacing the joint with the aim of retaining ankle joint movement. It is difficult for a patient to know which treatment is more suitable for them, with most seeking guidance from their surgeon,” he said.

Generating high-quality evidence

The study, a randomized, multicenter, open-label trial known as TARVA (Total Ankle Replacement Versus Ankle Arthrodesis), aimed to compare the clinical effectiveness of the two existing publicly funded U.K. treatment options, the authors wrote.

Patients were recruited at 17 U.K. centers between March 6, 2015, and Jan. 10, 2019. The study enrolled 303 adults aged 50-85 years with end-stage ankle osteoarthritis. The mean age of the participants was 68 years; 71% were men. A total of 137 TAR patients and 144 ankle fusion patients completed their surgeries with clinical scores available for analysis. Baseline characteristics were mainly similar between the groups.

Blinding was not possible because of the nature of the procedures, but the surgeons who screened the patients were not aware of the randomization allocations, the researchers noted. A total of 33 surgeons participated in the trial, with a median number of seven patients per surgeon during the study period.

For TAR, U.K. surgeons use both two-component, fixed-bearing and three-component, mobile-bearing implants, the authors write. Ankle fusion was done using the surgeon’s usual technique of either arthroscopic-assisted or open ankle fusion.

The primary outcome was the change in the Manchester–Oxford Foot Questionnaire walking/standing (MOXFQ-W/S) domain scores from baseline to 52 weeks after surgery. The MOXFQ-W/S uses a scale of 0-100, with lower scores representing better outcomes. Secondary outcomes included change in the MOXFQ-W/S scores at 26 weeks after surgery, as well as measures of patient quality of life.

No statistically significant difference

Overall, the mean MOXFQ-W/S scores improved significantly from baseline to 52 weeks for both groups, with average improvements of 49.9 in the TAR group and 44.4 points in the AF group. The average scores at 52 weeks were 31.4 in the TAR group and 36.8 in the AF group.

The adjusted difference in score change from baseline was –5.56, showing a slightly greater degree of improvement with TAR, but this difference was not clinically or statistically significant, the researchers noted.

Adverse event numbers were similar for both procedures, with 54% of TAR patients and 53% of AF patients experiencing at least 1 adverse event during the study period. Of those, 18% of TAR patients and 24% of AF patients experienced at least 1 serious adverse event.

However, the TAR patients experienced a higher rate of wound healing complications and nerve injuries, while thromboembolism was higher in the AF patients, the researchers noted.

A prespecified subgroup analysis of patients with osteoarthritis in adjacent joints suggested a greater improvement in TAR, compared with AF, a difference that increased when fixed-bearing TAR was compared with AF, the authors wrote.

“This reinforces previous reports that suggest that the presence of adjacent joint arthritis may be an indication for ankle replacement over AF,” the authors wrote in their discussion.

“Many of these patients did not have any symptoms in the adjacent joints,” they noted.

“The presence of adjacent joint arthritis, meaning the wear and tear of the joints around the ankle joint, seemed to favor ankle replacement,” Dr. Goldberg said. Approximately 30 joints in the foot continue to move after the ankle is fused, and if these adjacent joints are not healthy before surgery [as was the case in 42% of the study patients], the results of fusion were less successful, he explained.

A post hoc analysis between TAR subtypes showed that patients who had fixed-bearing TAR had significantly greater improvements, compared with AF patients, but this difference was not observed in patients who had mobile-bearing TAR, the researchers noted.

Dr. Goldberg said it was surprising “that, in a separate analysis, we found that the fixed-bearing ankle replacement patients [who accounted for half of the implants used] improved by a much greater difference when compared to ankle fusion.”

The study findings were limited by several factors including the short follow-up and study design that allowed surgeons to choose any implant and technique, the researchers noted.

Other limitations include a lack of data on cost-effectiveness and the impact of comorbidities on outcomes, they wrote. However, the study is the first completed multicenter randomized controlled trial to compare TAR and AF procedures for end-stage ankle osteoarthritis and shows that both yield similar clinical improvements, they concluded.

Data can inform treatment discussion

The take-home messages for clinicians are that both ankle replacement and ankle fusion are effective treatments that improve patients’ quality of life, and it is important to establish the health of adjacent joints before making treatment recommendations, Dr. Goldberg said.

“Careful counseling on the relative risks of each procedure should be part of the informed consent process,” he added. Ideally, all patients seeking surgical care for ankle arthritis should have a choice between ankle replacement and ankle fusion, but sometimes there is inequity of provision of the two treatments, he noted.

“We now encourage all surgeons to work in ankle arthritis networks so that every patient, no matter where they live, can have choice about the best treatment for them,” he said.

Researchers met the challenge of surgical RCT

Randomized trials of surgical interventions are challenging to conduct, and therefore limited, wrote Bruce Sangeorzan, MD, of the University of Washington, Seattle, and colleagues in an accompanying editorial. However, the new study was strengthened by the inclusion of 17 centers for heterogeneity of implant type and surgeon experience level, the editorialists said in the Annals of Internal Medicine.

The study is especially important, because ankle arthritis treatment is very understudied, compared with hip and knee arthritis, but it has a similar impact on activity, editorial coauthor Dr. Sangeorzan said in an interview.

“Randomized controlled trials are the gold standard for comparing medical therapies,” he said, “but they are very difficult to do in surgical treatments, particularly when the two treatments can be differentiated, in this case by movement of the ankle.”

In addition, there is a strong placebo effect attached to interventions, Dr. Sangeorzan noted. “Determining best-case treatment relies on prospective research, preferably randomized. Since both ankle fusion and ankle replacement are effective therapies, a prospective randomized trial is the best way to help make treatment decisions,” he said.

The current study findings are not surprising, but they are preliminary, and 1 year of follow-up is not enough to determine effectiveness, Dr. Sangeorzan emphasized. However, “the authors have done the hard work of randomizing the patients and collecting the data, and the patients can now be followed for a longer time,” he said.

“In addition, the trial was designed with multiple secondary outcome measures, so the data can be matched up with larger trials that were not randomized to identify key elements of success for each procedure,” he noted.

The key message for clinicians is that ankle arthritis has a significant impact on patients’ lives, but there are two effective treatments that can reduce the impact of the disease, said Dr. Sangeorzan. “The data suggest that there are differences in implant design and differences in comorbidities that should influence decision-making,” he added.

Additional research is needed in the form of a longer study duration with larger cohorts, said Dr. Sangeorzan. In particular, researchers need to determine what comorbidities might drive patients to one type of care vs. another, he said. “The suggestion that [patients receiving implants with two motion segments have better outcomes than those receiving implants with a one-motion segment] also deserves further study,” he added.

The research was supported by the UK National Institute for Health and Care Research Health Technology Assessment Programme. The trial was sponsored by University College London. Dr. Goldberg disclosed grant support from NIHR HTA, as well as financial relationships with companies including Stryker, Paragon 28, and stock options with Standing CT Company, Elstree Waterfront Outpatients, and X Bolt Orthopedics.

The editorialists had no financial conflicts to disclose.

Adults who underwent either total ankle replacement or ankle fusion for end-stage ankle osteoarthritis showed similar clinical scores and adverse event numbers, in a randomized controlled trial of approximately 300 patients.

Ankle osteoarthritis remains a cause of severe pain and disability. Patients are treated nonoperatively if possible, but surgery is often needed for individuals with end-stage disease, wrote Andrew Goldberg, MBBS, of University College London and colleagues in the Annals of Internal Medicine.

“Most patients with ankle arthritis respond to nonoperative treatments, such as weight loss, activity modification, support braces, and analgesia, [but] once the disease has progressed to end-stage osteoarthritis, the main surgical treatments are total ankle re-placement or ankle arthrodesis,” Dr. Goldberg said, in an interview.

In the new study, patients were randomized to receive either a total ankle replacement (TAR) or ankle fusion (AF).

“We showed that, in both treatment groups the clinical scores improved hugely, by more than three times the minimal clinically important difference,” Dr. Goldberg said in an interview.

“Although the ankle replacement arm improved, on average, by more than an extra 4 points over ankle fusion, this was not considered clinically or statistically significant,” he said.

The study is the first randomized trial to show high-quality and robust results, he noted, and findings support data from previous studies.

“Although both TAR and ankle fusion have been shown to be effective, they are very different treatments, with one fusing the bones so that there is no ankle joint movement, and the other replacing the joint with the aim of retaining ankle joint movement.

STOCKHOLM – Esmolol hydrochloride gel (Galnobax, NovoLead) appears to be a safe and effective novel topical treatment option for diabetic foot ulcers, according to results from a new trial of the drug, which is widely available as a generic and is inexpensive.

Of note, the proportion of participants achieving target ulcer closure at 12 weeks with esmolol (plus standard of care) was around 60% compared with just over 40% in patients who received standard of care alone.

Balkonsky/Thinkstock

Presenting the findings at this year’s annual meeting of the European Association for the Study of Diabetes was Ashu Rastogi, MD, a professor of endocrinology at the Postgraduate Institute of Medical Education and Research in Chandigarh, India.

“Esmolol can be given topically as a 14% gel and is a novel treatment option in diabetic foot ulcer,” said Dr. Rastogi.

Esmolol, a short-acting beta-adrenergic blocker, is currently approved by the U.S. Food and Drug Administration for cardiac indications only, such as short-term use for controlling supraventricular tachycardia. Beta-blockers are also used to treat hypertension.

However, esmolol has also been repurposed and formulated as a topical gel for the treatment of hard-to-heal diabetic foot ulcers (mainly neuropathic grade 1).

Audience member Ketan Dhatariya, MBBS, MD, PhD, a National Health Service consultant in diabetes, endocrinology, and general medicine and honorary senior lecturer at Norfolk and Norwich University Hospitals, England, enthused about the findings.

“This is an amazing study. I’m part of a working group looking at the updating of a guideline for the International Working Group of the Diabetic Foot, reviewing all the studies on wound healing, specifically pharmacological interventions. This is way beyond anything shown to date in terms of medical intervention. [The authors] should be congratulated; this is really astounding,” he told this news organization.

“Right now, there is very little out there in terms of pharmacological interventions that have shown benefit,” he added. “Once this study has been peer-reviewed and is published properly, it is potentially game-changing because it is a generic, worldwide, cheap, and freely available medication.”
 

Study across 27 sites in India

Prior phase 1/2 data have shown that 60% of ulcers completely closed with esmolol (14% gel) compared with 39% with standard of care.  Encouraged by these findings, a phase 3 randomized, double-blind placebo-controlled study was conducted across 27 sites in India.

Patients were a mean age of 56 years, and had a body mass index (BMI) of 25-26 kg/m² and mean hemoglobin A1c of 8.4%-8.7%. Around 70% of participants were men. Mean ulcer area was approximately 460-500 mm², two-thirds of the ulcers were plantar, and mean ulcer duration was 40-50 weeks.

After screening and discontinuations (39 participants), a 12-week treatment phase began with patients randomized to one of three groups: esmolol (14% gel) along with standard of care administered twice daily (57 completers); standard of care only (63 completers); or vehicle gel (placebo) along with standard of care administered twice daily (17 completers).

Standard of care comprised wound cleaning, debridement, maintenance of moist wound environment, twice-daily fresh bandages, and off-loading footwear as needed, and was provided to all participants irrespective of study group.

The 12-week treatment period was followed by an observation period of 12 weeks up to the 24-week study endpoint.

The primary efficacy endpoint was the proportion of participants achieving target ulcer closure (100% re-epithelialization without drainage or dressing requirement) within the 12-week treatment phase.

Secondary endpoints included time to target ulcer closure during the 12-week treatment phase and proportion of participants achieving target ulcer closure by 24 weeks (end of study). Investigators were blinded throughout.

Subanalyses were conducted based on ulcer location, size, and age, as well as estimated glomerular filtration rate less than 90 mL/min and ankle-brachial index under 0.9 but greater than 0.7.
 

50% more patients on esmolol had complete ulcer closure

The proportion of participants with complete ulcer closure at 12 weeks was 60.3% in the esmolol plus standard of care group, compared with 41.7% with standard of care only, a difference of 18.6% (odds ratio, 2.13; P = .0276).  

“The 24-week end-of-study data show what happened in the 12 weeks following end of treatment,” said Dr. Rastogi, turning to results showing that by 24 weeks the proportion of participants with complete ulcer closure was 77.2% versus 55.6%, respectively, with a difference of 21.6% (OR, 2.71; P = .013).

Time to ulcer closure (a secondary endpoint) was similar between the esmolol plus standard of care vs. standard of care groups (74.3 vs. 72.5 days).

The impact of ulcer location on complete ulcer closure, a subanalysis, showed a higher proportion of patients experienced complete ulcer closure with esmolol plus standard of care versus standard of care. For example, in plantar-based ulcers, esmolol led to complete closure in 58.7% vs. 43.1%, while for nonplantar ulcers, complete closure was found in 63.6% vs. 38.1%.

In wounds less than 5 cm², the proportion of complete closures was 66.0% vs. 50.0% for esmolol compared with standard of care alone, while in wounds over 5 cm², these proportions were 47.6% vs. 26.9%.

Subanalyses also showed that esmolol was substantially better in patients with BMI greater than 25, ulcer duration over 12 weeks, and A1c above 8%.

Also, a subanalysis stratified by “real-life” situations favored esmolol, showing a 50.9% difference in the proportion of patients with diabetic foot ulcer healing in those with a history of hypertension and a 31.8% difference favoring esmolol in those with an abnormal electrocardiogram.

Overall, the proportions of patients who had an adverse event were 13.2%, 18.4%, and 37.5% in the esmolol plus standard of care, standard of care alone, and vehicle plus standard of care groups, respectively, and the vast majority were unrelated to study drug. There were no serious adverse events in the esmolol plus standard of care group.
 

A class effect of beta blockers?

The proposed mechanism of action of esmolol relates to a sequence of reducing inflammation (via vasodilation, fibroblast migration, and cytokine reduction); proliferation by beta-blockade (improves keratinocyte migration and epithelialization); and remodeling (increases collagen turnover).

Asked by an audience member if the observations were a class effect and systemic effect of beta-blockers, Dr. Rastogi said he could not say for sure that it was a class effect, but they deliberately used a beta-1 adrenergic receptor antagonist.

“It may not be a systemic effect because we have some patients who use beta-blockers systemically and they still have diabetic foot ulcers,” he said.

Dr. Rastogi and Dr. Dhatariya have reported no relevant financial relationships.

Esmolol, a short-acting beta-adrenergic blocker, is currently approved by the U.S. Food and Drug Administration for cardiac indications only, such as short-term use for controlling supraventricular tachycardia. Beta-blockers are also used to treat hypertension.

However, esmolol has also been repurposed and formulated as a topical gel for the treatment of hard-to-heal diabetic foot ulcers (mainly neuropathic grade 1).

Audience member Ketan Dhatariya, MBBS, MD, PhD, a National Health Service consultant in diabetes, endocrinology, and general medicine and honorary senior lecturer at Norfolk and Norwich University Hospitals, England, enthused about the findings.

“This is an amazing study. I’m part of a working group looking at the updating of a guideline for the International Working Group of the Diabetic Foot, reviewing all the studies on wound healing, specifically pharmacological interventions. This is way beyond anything shown to date in terms of medical intervention. [The authors] should be congratulated; this is really astounding,” he told this news organization.

“Right now, there is very little out there in terms of pharmacological interventions that have shown benefit,” he added. “Once this study has been peer-reviewed and is published properly, it is potentially game-changing because it is a generic, worldwide, cheap, and freely available medication.”
 

Study across 27 sites in India

Prior phase 1/2 data have shown that 60% of ulcers completely closed with esmolol (14% gel) compared with 39% with standard of care.  Encouraged by these findings, a phase 3 randomized, double-blind placebo-controlled study was conducted across 27 sites in India.

Patients were a mean age of 56 years, and had a body mass index (BMI) of 25-26 kg/m² and mean hemoglobin A1c of 8.4%-8.7%. Around 70% of participants were men. Mean ulcer area was approximately 460-500 mm², two-thirds of the ulcers were plantar, and mean ulcer duration was 40-50 weeks.

After screening and discontinuations (39 participants), a 12-week treatment phase began with patients randomized to one of three groups: esmolol (14% gel) along with standard of care administered twice daily (57 completers); standard of care only (63 completers); or vehicle gel (placebo) along with standard of care administered twice daily (17 completers).

Standard of care comprised wound cleaning, debridement, maintenance of moist wound environment, twice-daily fresh bandages, and off-loading footwear as needed, and was provided to all participants irrespective of study group.

The 12-week treatment period was followed by an observation period of 12 weeks up to the 24-week study endpoint.

The primary efficacy endpoint was the proportion of participants achieving target ulcer closure (100% re-epithelialization without drainage or dressing requirement) within the 12-week treatment phase.

Secondary endpoints included time to target ulcer closure during the 12-week treatment phase and proportion of participants achieving target ulcer closure by 24 weeks (end of study). Investigators were blinded throughout.

Subanalyses were conducted based on ulcer location, size, and age, as well as estimated glomerular filtration rate less than 90 mL/min and ankle-brachial index under 0.9 but greater than 0.7.
 

50% more patients on esmolol had complete ulcer closure

The proportion of participants with complete ulcer closure at 12 weeks was 60.3% in the esmolol plus standard of care group, compared with 41.7% with standard of care only, a difference of 18.6% (odds ratio, 2.13; P = .0276).  

“The 24-week end-of-study data show what happened in the 12 weeks following end of treatment,” said Dr. Rastogi, turning to results showing that by 24 weeks the proportion of participants with complete ulcer closure was 77.2% versus 55.6%, respectively, with a difference of 21.6% (OR, 2.71; P = .013).

Time to ulcer closure (a secondary endpoint) was similar between the esmolol plus standard of care vs. standard of care groups (74.3 vs. 72.5 days).

The impact of ulcer location on complete ulcer closure, a subanalysis, showed a higher proportion of patients experienced complete ulcer closure with esmolol plus standard of care versus standard of care. For example, in plantar-based ulcers, esmolol led to complete closure in 58.7% vs. 43.1%, while for nonplantar ulcers, complete closure was found in 63.6% vs. 38.1%.

In wounds less than 5 cm², the proportion of complete closures was 66.0% vs. 50.0% for esmolol compared with standard of care alone, while in wounds over 5 cm², these proportions were 47.6% vs. 26.9%.

Subanalyses also showed that esmolol was substantially better in patients with BMI greater than 25, ulcer duration over 12 weeks, and A1c above 8%.

Also, a subanalysis stratified by “real-life” situations favored esmolol, showing a 50.9% difference in the proportion of patients with diabetic foot ulcer healing in those with a history of hypertension and a 31.8% difference favoring esmolol in those with an abnormal electrocardiogram.

Overall, the proportions of patients who had an adverse event were 13.2%, 18.4%, and 37.5% in the esmolol plus standard of care, standard of care alone, and vehicle plus standard of care groups, respectively, and the vast majority were unrelated to study drug. There were no serious adverse events in the esmolol plus standard of care group.
 

A class effect of beta blockers?

The proposed mechanism of action of esmolol relates to a sequence of reducing inflammation (via vasodilation, fibroblast migration, and cytokine reduction); proliferation by beta-blockade (improves keratinocyte migration and epithelialization); and remodeling (increases collagen turnover).

Asked by an audience member if the observations were a class effect and systemic effect of beta-blockers, Dr. Rastogi said he could not say for sure that it was a class effect, but they deliberately used a beta-1 adrenergic receptor antagonist.

“It may not be a systemic effect because we have some patients who use beta-blockers systemically and they still have diabetic foot ulcers,” he said.

Dr. Rastogi and Dr. Dhatariya have reported no relevant financial relationships.

STOCKHOLM – Esmolol hydrochloride gel (Galnobax, NovoLead) appears to be a safe and effective novel topical treatment option for diabetic foot ulcers, according to results from a new trial of the drug, which is widely available as a generic and is inexpensive.

Of note, the proportion of participants achieving target ulcer closure at 12 weeks with esmolol (plus standard of care) was around 60% compared with just over 40% in patients who received standard of care alone.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

lyosha_nazarenko/Thinkstock

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
 

Noncardiac surgery risk categories

The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:

• Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
• Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
• High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.

The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
 

Noncardiac surgery risk categories

The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:

• Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
• Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
• High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.

The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

Practice has gone back and forth on whether atrial fibrillation (AFib) should be considered in the preoperative cardiovascular risk (CV) evaluation of patients slated for noncardiac surgery, and the Revised Cardiac Risk Index (RCRI), currently widely used as an assessment tool, doesn’t include the arrhythmia.

But consideration of preexisting AFib along with the RCRI predicted 30-day mortality more sharply than the RCRI alone in an analysis of data covering several million patients slated for such procedures.

• 1.31 (95% CI, 1.30-1.33) for heart failure
• 1.40 (95% CI, 1.37-1.43) for stroke
• 1.59 (95% CI, 1.43-1.75) for systemic embolism
• 1.14 (95% CI, 1.13-1.16) for major bleeding  
• 0.81 (95% CI, 0.79-0.82) for MI

Those with preexisting AFib also had longer hospitalizations at a median 5 days, compared with 4 days for those without such AFib (P < .001).

The study has the limitations of most any retrospective cohort analysis. Other limitations, the report notes, include lack of information on any antiarrhythmic meds given during hospitalization or type of AFib.

For example, AFib that is permanent – compared with paroxysmal or persistent – may be associated with more atrial fibrosis, greater atrial dilatation, “and probably higher pressures inside the heart,” Dr. Mentias observed.

“That’s not always the case, but that’s the notion. So presumably people with persistent or permanent atrial fib would have more advanced heart disease, and that could imply more risk. But we did not have that kind of data.”

Dr. Mentias and Dr. Prasada report no relevant financial relationships; disclosures for the other authors are in the report. Dr. Curtis discloses serving on advisory boards for Abbott, Janssen Pharmaceuticals, Sanofi, and Milestone Pharmaceuticals; receiving honoraria for speaking from Medtronic and Zoll; and serving on a data-monitoring board for Medtronic. Dr. Korada reports he has no relevant financial relationships.

Bone marrow derived autologous cell therapy (ACT) has been shown to significantly reduce the rate of major amputation at 5 years in people with diabetes who developed critical limb-threatening ischemia (CLTI).

In a study of 130 patients, 64% of 42 patients who were treated conservatively needed a major amputation at 5 years versus just 30% of 45 patients who had been treated with ACT (P = .011).

This compared favorably to the results seen with repeated percutaneous angioplasty (re-PTA), where just 20.9% of 43 patients underwent limb salvage (P = .002 vs. conservative therapy).

Furthermore, amputation-free survival was significantly longer in both active groups, Michal Dubský, MD, PhD, FRSPH, reported at the annual meeting of the European Association for the Study of Diabetes.

Dr. Dubský, of the Institute for Clinical and Experimental Medicine and Charles University in Prague, also reported that fewer patients who had undergone re-PTA or ACT than conservative treatment had died by 5 years (25.8% and 35.6%, respectively, vs. 61.9%), but that the difference was significant only for the revascularization procedure (P = .012).

Based on these findings, “we believe that autologous cell therapy seems to be an appropriate alternative to repeated PTA even for patients with no-option chronic limb-threatening ischemia,” he said.

“This is a very important area,” said Andrew J.M. Boulton, MBBS, MD, FRCP, who chaired the oral abstract presentation session during which the findings were presented.

“It is very difficult to get an evidence base from randomized studies in this area, because of the nature of the patients: They’re very sick and we all deal with them in our clinics very regularly,” added Dr. Boulton, professor of medicine within the division of diabetes, endocrinology and gastroenterology at the University of Manchester (England).

Dr. Boulton called the findings a “very important addition to what we know.”
 

New option for no-option CLTI

CLTI is associated with persistent pain at rest, ulcers, and gangrene, and can be the end result of longstanding peripheral arterial disease. Within the first year of presentation, there’s a 30% chance of having a major amputation and a 25% chance of dying.

Importantly, said Dr. Dubský, “there is a big difference in this diagnosis” between patients with diabetes and those without. For instance, CLTI is more diffuse in patients with diabetes than in those without, different arteries are affected and the sclerosis seen can be more rigid and “full of calcium.”

While surgery to improve blood flow is the standard of care, not everyone is suitable. Bypass surgery or endovascular procedures can be performed in only 40%-50% of patients, and even then a therapeutic effect may be seen in only a quarter of patients.

“We need some new therapeutic modalities for this diagnosis, and one of them could be autologous cell therapy,” said Dr. Dubský.
 

Study details

Dr. Dubský and coinvestigators consecutively recruited 130 patients with diabetic foot and CLTI who had been seen at their clinic over a 5-year period. Of these, 87 had not been eligible for standard revascularization and underwent ACT or were treated conservatively.

Of the patients who were not eligible for standard revascularization (‘no-option CLTI), 45 had undergone ACT and 42 had been treated conservatively. Dr. Dubský acknowledged that “his study was not prospective and randomized.”

All patients in the study had at least one unsuccessful revascularization procedure and diabetic foot ulcers, and low tissue oxygenation. The latter was defined as transcutaneous oxygen pressure (TcPO₂) of below 30 mm Hg.

There were little differences in demographic characteristics between the treatment groups, the average age ranged from 62 to 67 years, there were more men (70%-80%) than women; most patients (90%) had type 2 diabetes for at least 20 years. There were similar rates of ischemic heart disease, hypertension, dialysis, and immunosuppressive therapy.

There were no differences in baseline values of TcPO₂ between the groups, and similar improvements were seen in both the ACT and re-PTA groups versus conservative group.
 

ACT in practice

With such promising results, what about the practicalities of harvesting a patient’s bone marrow to make the ACT?

“Bone marrow harvesting usually takes about 20 minutes,” Dr. Dubský said. It then takes another 45 minutes to separate the cells and make the cell suspension, and then maybe another 10 minutes or so to administer this to the patient, which is done by injecting into the calf muscles and small muscles of the foot, aided by computed tomography. The whole process may take up to 2 hours, he said.

“Patients are under local or general anesthesia, so there is no pain during the procedure,” Dr. Dubský reassured. “Afterwards we sometimes see small hematoma[s], with low-intensity pain that responds well to usual analgesic therapy.”

Computed tomography was used to help guide the injections, which was advantageous, Dr. Boulton pointed out, because it was “less invasive than angioplasty in these very sick people with very distal lesions, many of whom already have renal problems.”

“It is surprising though, that everybody had re-PTA and not one had vascular surgery,” he suggested. Dr. Boulton added, however: “These are very important observations; they help us a lot in an area where there’s unlikely to be a full RCT.”

The next step in this research is to see if combining ACT and re-PTA could lead to even better results.

The study was funded by the Czech Republic Ministry of Health. Dr. Dubský had nothing to disclose. Dr. Boulton made no statement about his conflicts of interest.
