SAN FRANCISCO – There’s no need to wait for western blot results to differentiate Lyme arthritis from septic arthritis in children, as long as your lab, like many, uses the Liaison Borrelia burgdorferi assay, according to investigators at the University of Minnesota, Minneapolis.

Acute, isolated monoarthritis presents with a single swollen joint and pain whether it’s due to Lyme disease or infection, so it’s hard to tell them apart. Current guidelines recommend a two-tier approach to diagnose Lyme arthritis, an initial blood screen followed by western blot confirmation. Screening results come back in a few hours, but western blot confirmation can take days.

In the meantime, children are treated presumptively for the more concerning diagnosis – septic arthritis – which means hospitalization, surgical drainage, and IV antibiotics. Those who turn out to have Lyme are exposed to the risks and costs of unnecessary treatment and delays to proper diagnosis and doxycycline.

When “kids come in with a swollen knee, maybe 10% or 15% end up in the hospital being treated for septic arthritis that they never had. I wanted to see if we can diagnose Lyme arthritis more quickly,” said lead investigator Bazak Sharon, MD, a pediatric infectious disease specialist at the university’s Masonic Children’s Hospital.

Masonic and its affiliated health system use the Liaison Borrelia burgdorferi assay (DiaSorin) to screen for Lyme, and a careful parsing of the results seems to solve the problem.

Liaison is a chemiluminescence immunoassay that uses light to measure IgM and IgG antibodies to a B. burgdorferi surface protein in serum samples. Results are reported as relative light units (RLUs); below 0.9 RLUs is negative; 0.9-1.1 is equivocal, and over 1.1 is positive.

It’s where patients fall in the range of positivity that matters when it comes to differentiating Lyme from septic arthritis, Dr. Sharon said at ID Week, an annual scientific meeting on infectious diseases (Clin Vaccine Immunol. 2008 Dec;15[12]:1796-804).

He and his team reviewed 60 cases of acute, isolated monoarthritis culled from more than 700 children who presented with joint complaints from 2011 to 2016; 47 had Lyme arthritis confirmed by western blot; 13 had septic arthritis.

It turned out that “every single patient with a” Liaison value of 9 RLUs or higher was confirmed on western blot for Lyme. “Under 9, there was not a single case of Lyme arthritis,” Dr. Sharon said. Three other patients with acute arthritis also tested positive on the screen, but their RLU values were below 4; two turned out to be trauma related and one was ultimately diagnosed with juvenile idiopathic arthritis. Western blots were negative in all three.

The RLU number reported on the screening test “appears to correlate very well with Lyme arthritis. In an otherwise healthy child presenting with acute joint swelling, utilizing this screening test can confirm clinical suspicion of Lyme arthritis within hours, and prevent the potential harmful interventions accompanying a misdiagnosis of septic arthritis. Just do the screening. If it comes up above 9, you’ve got Lyme arthritis,” and don’t need to wait for western blot results to treat, Dr. Sharon said.

In other words, above 9, treat for Lyme.

The investigators plan to delve further into their results with sensitivity/specificity and other analyses before publishing. Ultimately, “my goal is to have a better diagnosis algorithm for kids who present with acute, isolated monoarthritis,” Dr. Sharon said.

There was no industry funding for the work, and the investigators didn’t have any disclosures.

SAN DIEGO – Angiograms can be deceiving, so it’s best to measure fractional flow reserve (FFR) across coronary obstructions to gauge patients’ true need for intervention. That’s hardly news to cardiologists, but FFR is not often done. The problem is that traditional measurement requires threading wires down coronary arteries; the technique is a bit risky and takes time and training. It also has to be repeated for each lesion.
 

But now, several companies are developing noninvasive ways to measure FFR.

Findings from one of them, CathWorks, were presented at the Transcatheter Cardiovascular Therapeutics annual meeting sponsored by the Cardiovascular Research Foundation. Its FFRangio system uses high-quality angiograms and an algorithm to estimate resistance and flow across stenoses. After a few cases, the process takes less than 5 minutes (Circulation. 2018 Sep 24. doi: 10.1161/CIRCULATIONAHA.118.037350).

“I think this is a big breakthrough. ... Ultimately, it should lead to better patient outcomes,” said lead investigator William Fearon, MD, professor of cardiology at Stanford University, Calif.

In an interview at TCT 2018, Dr. Fearon explained the importance of FFR, the data for FFRangio, and what’s coming down the pike from other companies. He disclosed institutional research grants from the company.

SAN FRANCISCO – Intravenous metronidazole (Flagyl) did not improve 30-day mortality when it was added to oral vancomycin in adult ICU patients with severe Clostridium difficile infections, according to a review of 101 cases at the University of Maryland.

Adding metronidazole is a common move in ICUs when patients start circling the drain with C. difficile, in part because delivery to the gut doesn’t depend on gut motility. “At that point, you are throwing the kitchen sink at them, but it’s” based, like much in C. difficile management, on expert opinion, not evidence, said study lead Ana Vega, PharmD, a former resident at the university’s school of pharmacy in Baltimore, and now an infectious disease pharmacist at Jackson Memorial Hospital, Miami. The investigators wanted to plug the evidence gap. Forty-seven of the 101 patients in their review – all with signs of C. difficile sepsis – had IV metronidazole added to their vancomycin regimens. Thirty-day mortality was 14.9% in the combination group versus 7.4% in the monotherapy arm, and not significantly different (P = .338). There were also no significant differences in resolution rates or normalization of white blood cell counts and temperature.

“Our data question the utility of” of adding IV metronidazole to oral vancomycin in patients with severe disease. “It’s definitely something to think twice about because metronidazole isn’t benign. It makes people feel crummy; you can induce resistance; and it increases the risk of vancomycin-resistant Enterococci colonization,” already a risk with vancomycin, Dr. Vega said at an annual scientific meeting on infectious diseases.

“When you get to the point that you are trying combination therapy based on expert opinion, I think fecal transplants are something to consider” because the success rates are so high. “That would be my suggestion,” she said, even though “it’s much easier to write an order for a drug than to get a fecal transplant.”

The issue is far from resolved, and debate will continue. A similar review of ICU patients at Wake Forest University in Winston-Salem, N.C., did find a significant mortality benefit with combination therapy, regardless of C. difficile severity (Clin Infect Dis. 2015 Sep 15. doi: 10.1093/cid/civ409).

The Maryland investigators excluded patients with toxic megacolon and other life-threatening intra-abdominal complications requiring surgery, because combination therapy is more strongly recommended in fulminant disease. They were interested in people who were not quite ready for the operating room, when what to do is more in doubt.

Subjects were admitted to the ICU from April 2016 to April 2018 with positive C. difficile nucleic acid testing and an order for oral vancomycin. The only statistically significant baseline differences were that patients who got IV metronidazole had higher median white blood cell counts (18,400 versus 13,900 cells/mL; P = .035) and were more likely to receive higher than 500-mg doses of vancomycin (36.2% versus 7.4%; P less than .0001).

The Mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score in the combination group was 23 versus 19 in the monotherapy arm (P = .247). There was no difference in the probability of receiving metronidazole based on the score.

The study again found no significant 30-day mortality differences among 76 patients matched by their APACHE II scores (15.8% in the combination arm versus 9.7%; P = .480).

Severe C. difficile infection was defined as either a white cell count above 15,000 or below 4,000 cells/mL, or a serum creatinine at least 1.5 times above baseline, plus at least one other sign of severe sepsis, such as a mean arterial pressure at or below 60 mm Hg. Metronidazole was started within 72 hours of the first vancomycin dose, and subjects on combination therapy were on both for at least 72 hours.

The mean age in the study was about 60 years old, and just over half of the subjects were men.

Dr. Vega said the investigators hope to expand their sample size and see if patients with more virulent strains of C. difficile do better on combination therapy.

There was no industry funding for the work, and the investigators didn’t have any relevant disclosures.

SAN FRANCISCO – The University of Kentucky Medical Center, Lexington, halved the rate of MRSA and CRE infections in the ICU by switching from contact precautions to decolonization with nasal povidone iodine swabs and daily chlorhexidine wipes, according to a report presented at ID Week 2018.

M. Alexander Otto/MDedge News

The move prevented an estimated eight methicillin-resistant Staphylococcus aureus (MRSA) and three carbapenem-resistant Enterobacteriaceae (CRE) infections and saved the medical center more than $150,000 in the year following the November 2016 switch.

The goal was to address the rate of MRSA bacteremia, which was higher than national ICU averages. Contact precautions began to make less sense as MRSA became more common in the surrounding community, and “we just wanted to get rid of contact precautions,” said study lead Jason Moss, DO, an infectious disease fellow at the university.

Contact precautions are expensive, make patients feel isolated, and according to some studies, lead to worse outcomes, he said at the annual scientific meeting on infectious diseases.

Decolonization is not routine in most ICUs, but it’s gaining traction. Guidelines recommend chlorhexidine bathing with wipes to stop CRE transmission, and chlorhexidine is used to prevent central line–associated bloodstream infections (CLABSI).

A recent analysis of 17 trials found marked decreases in MRSA and CLABSI with decolonization and concluded that chlorhexidine bathing “appears to be of the most clinical benefit when infection rates are high for a given ICU population,” as was the case in Kentucky (Crit Care. 2016 Nov 23;20[1]:379).

When researchers compared the year before the change to the year after, “we were pretty surprised at how much the rates of infection and colonization decreased. There have been some people that have been doing this in the ICU, but probably not to our extent. If you want to get rid of contact precautions, this is a great process to do it with,” Dr. Moss said.

Rates of colonization with MRSA or CRE fell from about 14 isolates per 10,000 patient-days to fewer than 6 (P = .026). Infection rates fell from 3.9 isolates per 10,000 patient-days to 2 (P = .083). Combined rates of infections and colonizations fell from almost 18 isolates per 10,000 patient-days to fewer than 8 (P = .010).

Decolonization is now standard practice at the university. Every ICU patient gets a one-time povidone iodine nasal swab at admission, then daily baths with 2% chlorhexidine gluconate applied by impregnated wipe. It usually takes four or five wipes to do the entire body.

Spending on gowns fell from about $153,000 per year to just under $60,000, but spending on wipes went up from about $2,700 to $275,000, and spending on povidone iodine nasal swabs went up to more than $100,000.

When balanced against the money not spent on those 11 prevented infections, however, the program saved the medical center about $152,000 in its first year, according to Dr. Moss and his team.

There was no funding for the work, and the investigators had no disclosures.

When balanced against the money not spent on those 11 prevented infections, however, the program saved the medical center about $152,000 in its first year, according to Dr. Moss and his team.

There was no funding for the work, and the investigators had no disclosures.

SAN FRANCISCO – The University of Kentucky Medical Center, Lexington, halved the rate of MRSA and CRE infections in the ICU by switching from contact precautions to decolonization with nasal povidone iodine swabs and daily chlorhexidine wipes, according to a report presented at ID Week 2018.

M. Alexander Otto/MDedge News

The move prevented an estimated eight methicillin-resistant Staphylococcus aureus (MRSA) and three carbapenem-resistant Enterobacteriaceae (CRE) infections and saved the medical center more than $150,000 in the year following the November 2016 switch.

The goal was to address the rate of MRSA bacteremia, which was higher than national ICU averages. Contact precautions began to make less sense as MRSA became more common in the surrounding community, and “we just wanted to get rid of contact precautions,” said study lead Jason Moss, DO, an infectious disease fellow at the university.

Contact precautions are expensive, make patients feel isolated, and according to some studies, lead to worse outcomes, he said at the annual scientific meeting on infectious diseases.

Decolonization is not routine in most ICUs, but it’s gaining traction. Guidelines recommend chlorhexidine bathing with wipes to stop CRE transmission, and chlorhexidine is used to prevent central line–associated bloodstream infections (CLABSI).

A recent analysis of 17 trials found marked decreases in MRSA and CLABSI with decolonization and concluded that chlorhexidine bathing “appears to be of the most clinical benefit when infection rates are high for a given ICU population,” as was the case in Kentucky (Crit Care. 2016 Nov 23;20[1]:379).

When researchers compared the year before the change to the year after, “we were pretty surprised at how much the rates of infection and colonization decreased. There have been some people that have been doing this in the ICU, but probably not to our extent. If you want to get rid of contact precautions, this is a great process to do it with,” Dr. Moss said.

Rates of colonization with MRSA or CRE fell from about 14 isolates per 10,000 patient-days to fewer than 6 (P = .026). Infection rates fell from 3.9 isolates per 10,000 patient-days to 2 (P = .083). Combined rates of infections and colonizations fell from almost 18 isolates per 10,000 patient-days to fewer than 8 (P = .010).

Decolonization is now standard practice at the university. Every ICU patient gets a one-time povidone iodine nasal swab at admission, then daily baths with 2% chlorhexidine gluconate applied by impregnated wipe. It usually takes four or five wipes to do the entire body.

SAN FRANCISCO – The new herpes zoster subunit vaccine (Shingrix) is on the short list of essential vaccines for immunocompromised adults, including those on biologics.

Ongoing research is demonstrating efficacy and safety in renal transplants patients, as well as those with hematologic cancer and stem cell transplants, according to Lorry Rubin, MD, director of pediatric infectious diseases at Cohen Children’s Medical Center, Queens, and professor of pediatrics at Hofstra University, Hempstead, N.Y.

Immunocompromised people, including those on biologics, should be immunized against a variety of diseases just like everyone else, but it’s tricky. There’s considerable variability in how biologics affect the immune system and subsequent vaccine potency. Timing is important, and although live vaccines are generally a no-go, there’s one class of biologics with which they’re safe, he said.

In a wide-ranging interview at IDWeek 2018, an annual scientific meeting on infectious diseases, Dr. Rubin shared his advice on immunizing the immunocompromised, including the other vaccines on the short list. He also tackled the common concern that vaccinations might trigger rejection in transplant patients.

He’s well qualified to address the issues: Dr. Rubin was lead author on the 2013 Infectious Diseases Society of America guidelines on vaccinating immunocompromised patients.

SAN FRANCISCO – Direct-acting antiretrovirals are more effective than pegylated interferon/ribavirin in reducing cardiovascular risk in people with hepatitis C virus, according to a review of over 30,000 patients in the ERCHIVES (Electronically Retrieved Cohort of HCV Infected Veterans) database of the Veterans Health Administration system.

In the study, 12,667 patients were treated with direct-acting antiretrovirals (DAAs) and 4,436 with pegylated interferon/ribavirin (PEG/RBV). Each subject was matched to an untreated control based on alcohol use, diabetes, and other confounders. Patients with HIV, hepatitis B, or previously diagnosed cardiovascular disease were excluded.

Over a follow-up of about 10 years, there were 2,361 strokes, heart attacks, or other cardiovascular (CV) events among untreated patients, which translated to an incidence of 30.9 events per 1,000 patient years. In the PEG/RBV group, there were 804 events, yielding an incidence of 23.5 per 1,000 patient years. The DAA group fared better, with 435 events and an incident rate of 16.3.

Sustained virologic response also was associated with lower CV risk, and the odds of attaining it were about 25% greater with DAAs vs. PEG/RBV. That might have played a role in the findings, since hepatitis C is known to be associated with CV disease and the virus has been found in atherosclerotic plaques.

Past investigations have been mixed on whether or not hepatitis C virus treatment reduces CV risk, but lead investigator Adeel Ajwad Butt, MD, professor of medicine at Cornell University, New York, said that his study was stronger than what has come before. He explained why, and also why the findings matter, in an interview at ID Week 2018, an annual scientific meeting on infectious diseases.

Most of the subjects were men, about a quarter were black, and the median age at baseline was 58 years.

Dr. Butt disclosed institutional research grants from Merck and Gilead.

SAN FRANCISCO – Clinicians prescribed 46% of antibiotics without an infection-related diagnosis code and 20% without an office visit, based on a review of more than half a million outpatient prescriptions to more than a quarter million patients at 514 clinics around Chicago.

The researchers looked to see if prescriptions had an ICD-10 code that indicated an antibiotic; they were liberal in their approach, considering over 21,000 codes to at least possibly signal the need for an antibiotic.

Almost half the time, there was nothing in the codes related to bacterial infection: 29% of scripts were written in connection with codes for high blood pressure, annual visits, and other noninfectious disorders; 17% of prescriptions were written with no diagnosis code at all.

The study is likely the largest to date to look at outpatient antibiotic prescribing patterns in the United States, and the findings are worrisome. “Nearly half the time, clinicians have either a bad reason for prescribing antibiotics, or don’t provide a reason at all. When you consider about 80% of antibiotics are prescribed on an outpatient basis, that’s a concern,” lead investigator Jeffrey A. Linder, MD, MPH, chief of the division of general internal medicine and geriatrics at Northwestern University, Chicago, said in a written statement.

“At busy clinics, sadly, the most efficient thing to do is just call in an antibiotic prescription. We need to dig into the data more, but we believe there is a lot of antibiotic prescribing for colds, the flu, and non-specific symptoms such as just not feeling well,” he said.

With all the concern in recent years about overuse, it’s hard to imagine that prescribers are still being free and easy with antibiotics, and Dr. Linder’s study will certainly have its skeptics.

Sloppy record keeping could be one explanation for the findings. A patient could really have needed an antibiotic, but it just wasn’t captured in coding. There are also valid reasons for prescribing antibiotics over the phone, such as acne and recurrent UTIs.

Dr. Linder, however, thinks it’s more than that. He explained his study, its implications, and the next steps in an interview at ID Week, an annual scientific meeting on infectious diseases.

The 2,413 prescribers in the study included physicians, surgeons, residents, fellows, nurse practitioners, and physician assistants in general and specialty practices. Patients were a mean of 43 years old: 60% were women and 75% were white. The most common antibiotic classes were penicillins, macrolides, and cephalosporins. Prescriptions were written from November 2015 through October 2017.

The work was funded by the Agency for Healthcare Research and Quality. Dr. Linder did not have any disclosures.

SAN FRANCISCO – Children exposed to efavirenz in utero were 60% more likely than were those exposed to other antiretrovirals to later develop seizures, eye problems, and other neurologic abnormalities, according to a review of 3,747 children in the Surveillance Monitoring for ART Toxicities (SMARTT) study, an ongoing effort to monitor children exposed to antiretrovirals in the womb.

Overall, 237 children developed a neurologic complication at a mean age of 2; 16 of them were exposed to efavirenz. The study team estimated that 9.6% of children exposed to efavirenz had a neurological complication, versus 6.2% born to women on ART regimens without efavirenz. There was also a nonsignificant trend toward dolutegravir exposure and later neurological abnormalities, which occurred in four of 94 children exposed to the drug. Results were adjusted for maternal smoking and other risk factors.

No other safety signals were detected with the 19 other antiretrovirals analyzed in the study, lead investigator Claudia S. Crowell, MD, assistant professor of pediatrics at the University of Washington, Seattle, said at the annual scientific meeting on infectious diseases.

Efavirenz isn’t used much in the United States because there are more effective options with fewer side effects, but current guidelines recommend that women who are doing well on the drug stay on it while pregnant. Meanwhile, dolutegravir exposure at the time of conception was recently linked to an increased risk of neural tube defects in infants. The drug is commonly used in the United States, and guidelines have been strengthened to highlight the need for contraception use by women taking dolutegravir.

Dr. Crowell said she was surprised by her study’s findings, in part because efavirenz is not a teratogen. The work highlights how important it is to look beyond birth defects and follow children exposed to antiretrovirals for later problems. “We still haven’t determined what the safest regimen is for use in pregnancy,” she said.

Dr. Crowell explained the problem, and what her work means for practice in an interview at the meeting.

SAN FRANCISCO – There’s an increasing push in the United States to screen all newborns for congenital cytomegalovirus.

The reason is because most of the time the diagnosis of congenital cytomegalovirus is missed. Only about 10% of infants infected with the virus present with enlarged livers and other classic signs. Too often, the infection isn’t caught until later, when hearing loss and other neurologic sequelae reveal themselves, according to Fatima Kakkar, MD, a pediatric infectious disease specialist and researcher at the University of Montreal.

There are effective treatments – intravenous ganciclovir for 6 weeks or oral valganciclovir (Valcyte) for 6 months – that control the infection and reverse its effects.

People have tried to address the situation by screening children with hearing loss, in utero HIV exposure, or cytomegalovirus symptoms, but in a study Dr. Kakkar presented at IDWeek, an annual scientific meeting on infectious diseases, such targeted efforts still missed a lot of children.

Many think the answer is universal screening, and the Centers for Disease Control and Prevention are considering it. In a video interview at the meeting, Dr. Kakkar explained the issues, her study, and why universal screening is gaining support.

SAN DIEGO – Don’t be satisfied with a diagnosis of angina with no obstructive coronary artery disease; push for acetylcholine testing, the findings from a trial in Scotland suggest.

M. Alexander Otto/MDedge News

Going a little further with an acetylcholine challenge in the cath lab will usually uncover microvascular or vasospastic heart problems, and this can lead to appropriate treatment. Patients will have less angina and a better quality of life at 6 months, according to investigators from the University of Glasgow (Scotland).

Invasive angiography usually ends on both sides of the Atlantic when no occlusions are found. There are concerns about the safety of going further with acetylcholine challenges, and until now, there had been no grade A evidence from a randomized trial that it improves outcomes. The Glasgow team filled the evidence gap with their presentation of the Coronary Microvascular Angina (CorMicA) trial at the Transcatheter Cardiovascular Therapeutics (TCT) annual meeting, and there wasn’t a single serious adverse event (J Am Coll Cardiol. 2018 Sep 25. doi: 10.1016/j.jacc.2018.09.006).

“This was a proof-of-concept study, which we believe [should] substantiate a large, multicenter trial,” said senior investigator Colin Berry, PhD, a professor of cardiology and imaging at the university.

Acetylcholine was infused down the pressure wire in 151 subjects diagnosed with angina with no obstructive coronary artery diseases before they left the catheter lab. Of these patients, 76 were randomized to have their results shared with their treating cardiologist, and 75 were randomized to not have their results shared. Coronary functional testing is hardly ever done, so the no-share group was considered the standard-of-care control arm. The idea was to see whether it made a difference when treating physicians knew what was causing chest pain when their patients didn’t have occlusive disease.

It turned out to make a huge difference. The diagnosis of “chest pain of noncardiac origin” almost fell off the map. Once cardiologists knew what was going on, they switched up treatment according to European Society of Cardiology guidelines for functional heart pain. Patients with microvascular angina were given beta-blockers and switched off nitrates because these drugs make angina worse in microvascular disease. Subjects with vasospasms were shifted to calcium channel blockers and long-acting nitrates and away from beta-blockers because beta-blockers make vasospasms worse.

Cardiologists who didn’t know the results kept muddling along with what patients came in on at baseline – beta-blockers in two-thirds, long-acting nitrates in half, and calcium channel blockers in a third.

Subjects who got the right treatment because of acetylcholine testing outpaced the standard care group by almost 12 points on the Seattle Angina Questionnaire at 6 months; they could walk farther and didn’t have crushing angina almost every day (P = .001). They reported a statistically significant improvement in quality of life, and they were much happier with their doctors.

“This is the first randomized, sham-controlled trial in this space”; functional testing “was routinely safe and feasible. Therapy guided by the results of physiologic testing improved outcomes” and “treatment satisfaction,” said University of Glasgow interventional cardiologist Tom Ford, MD.

Acetylcholine was infused down the pressure wire into the radial artery, with the left anterior descending coronary artery as the target vessel. A final bolus of less than 100 mcg checked for coronary artery spasms; a symptomatic constriction of greater than 90% was considered positive. Glyceryl trinitrate was used to reverse the effects.

Three-quarters of the subjects were women, which Dr. Ford noted is unusual in an angina study. The mean age was 61 years, and subjects had about a 20% chance of a heart attack within 10 years. The whole procedure, including the angiogram, randomization, and functional testing, took a median of about 60 minutes.

There were no differences in major adverse cardiac events at 6 months, at 2.6% in both groups.

One patient developed persistent atrial fibrillation with acetylcholine testing that was converted to sinus rhythm with intravenous amiodarone, without a night in the hospital.

SAN DIEGO – Don’t be satisfied with a diagnosis of angina with no obstructive coronary artery disease; push for acetylcholine testing, the findings from a trial in Scotland suggest.

Going a little further with an acetylcholine challenge in the cath lab will usually uncover microvascular or vasospastic heart problems, and this can lead to appropriate treatment. Patients will have less angina and a better quality of life at 6 months, according to investigators from the University of Glasgow (Scotland).

Invasive angiography usually ends on both sides of the Atlantic when no occlusions are found. There are concerns about the safety of going further with acetylcholine challenges, and until now, there had been no grade A evidence from a randomized trial that it improves outcomes. The Glasgow team filled the evidence gap with their presentation of the Coronary Microvascular Angina (CorMicA) trial at the Transcatheter Cardiovascular Therapeutics (TCT) annual meeting, and there wasn’t a single serious adverse event (J Am Coll Cardiol. 2018 Sep 25. doi: 10.1016/j.jacc.2018.09.006).

“This was a proof-of-concept study, which we believe [should] substantiate a large, multicenter trial,” said senior investigator Colin Berry, PhD, a professor of cardiology and imaging at the university.
