Much has changed in the 10 years since Medscape’s first survey on what physicians would do when faced with painful choices in patient care.

A new report, Ethics 2020: Life, Death, and Painful Dilemmas, shows that physicians’ value judgments have shifted in many respects, sometimes as a result of increased regulations and fears of litigation.
 

 End-of-life decisions

Several of the questions in the survey revolved around end-of-life decisions, and in some cases, the differences seen in just a decade were striking. One example concerned life support decisions in the context of a family’s choices.

Age also seemed to play a role in the 2020 answers to that question: Physicians younger than 45 were more likely (28%) to answer “yes” (that they would withdraw life support in that instance) than were those 45 and older (16%).

A critical care physician said, “If the family appears to have an underlying motivation that may not be in the patient’s best interest, I might be inclined to pursue a legal decision prior to withdrawing support.”

A cardiologist had a more pointed response to the question: “To me, that would be murder.”

Another example of how perspectives have changed over the past 10 years concerns whether physician-aided dying should be legal for terminally ill patients. The practice is now mandated by law in eight states and the District of Columbia, and it is mandated by court ruling in two additional states.

In 2010, 41% said “no.” That number dropped to 28% in 2020.

On legalization, a psychiatrist said, “Yes, when there is truly no hope and the quality of remaining life is too poor. We show more compassion to our sick animals than we do to our human population.”

Conversely, a neurologist answered, “No, I see younger physicians already becoming comfortable with the idea of deciding ASAP whether there is a reasonable chance of survival and then pressing for the right code status. This change would make things worse.”
 

Assisted death and incurable suffering

Far fewer physicians supported physician-assisted death for those who had years to live but faced incurable suffering: Thirty-seven percent said “yes,” 34% said “no,” and 29% said “it depends.”

However, support was significantly higher than it was just 2 years ago, in 2018, when only 27% supported the concept, the report authors noted.

“The shift reflects movements by many states to legalize assisted dying for the terminally ill,” Arthur Caplan, PhD, director of the division of medical ethics, New York University, said in the report. “Legalization has not been abused, so some doctors are more willing to press further beyond terminal illness as a trigger to suffering.”

Conversely, many more physicians (44% vs. 24% a decade ago) said they would provide life-sustaining therapy if the family requested it, even if the physician thought it was futile.

“Concerns over a malpractice lawsuit and potential negative patient/family online reviews are factors that play into this change,” the survey authors wrote.

Shared decision making also increased in the past decade.
 

Would you undertreat pain?

Primary care physicians fear the consequences of what they consider adequate pain management more than specialists do (24% vs. 17%), the survey authors noted.

Ten years ago, Medscape asked physicians whether they would undertreat a patient’s pain because of fear of repercussions or the patient’s becoming addicted: Eighty-four percent said “no,” and 6% said “yes.” The rest said “it depends.”

In 2020, the question was asked slightly differently: “Would you undertreat a patient’s pain for fear of addiction or Drug Enforcement Administration or medical board scrutiny?” This year, three times as many said “yes” (18%); 63% said “no.”

“Respondents this year talked about investigations and reprimands by medical boards, and how much they wanted to avoid that,” the survey authors wrote.
 

 

 

Should physicians be required to treat COVID-19 patients?

Some questions were new this year, including one on whether physicians should be required to treat COVID-19 patients. Fewer than half (47%) answered “yes,” 24% said “no,” and 29% answered “it depends.”

Doctors’ answers to this question differed slightly by gender: Fifty percent of men and 43% of women said “yes.” In their responses, many physicians said consideration should be given to risk factors, such as age, underlying conditions, risk of family members, and availability of personal protective equipment (PPE).

Another pandemic-related question asked whether physicians felt they should correct physicians who post misinformation about the pandemic on social media. Half (50%) said “yes,” 19% said “no,” and 31% said “it depends.”
 

Speaking out against the workplace

This year, many physicians have felt betrayed when they didn’t have adequate PPE during the pandemic.

Asked, “Is it right to speak out against your hospital or workplace when they don’t give you what you need?” 53% of physicians said “yes,” 8% said “no,” and 40% said “it depends.”

A cardiologist made the value judgment this way: “Speaking out just because you had an argument with your boss is inappropriate. Bringing to the public repeated failures to correct situations that have been brought through the proper channels is necessary to incite change.”
 

Random drug testing for physicians?

Another question in the survey asked whether physicians should be subjected to random drug testing for alcohol and drug abuse. About one-third (34%) said yes, 43% said no, and 23% said “it depends.” A study found that between 10% and 15% of physicians have abused a substance at some point in their careers.

The subject continues to hit a nerve in medicine.

A family physician wrote, “This should not be done unless a particular physician had a problem with drug or alcohol abuse and shows signs of impairment.”

An internist took a different view, saying, “Military service men and women, police, firefighters, airline pilots, and other professions that have responsibilities affecting people’s lives are subject to testing; why not physicians?”

Liver-related deaths decline after Medicaid expansion under ACA

Liver-related deaths declined and liver transplant waitlist inequities decreased in states that implemented Medicaid expansion under the Affordable Care Act (ACA), results of an innovative study showed.

About 1 year after Medicaid expansion began on Jan. 1, 2014, the rate of liver-related mortality in 18 states that took advantage of expanded coverage began to decline, whereas the rate of liver-related deaths in 14 states that did not expand Medicaid continued to climb, reported Nabeel Wahid, MD, a resident at Weill Cornell Medicine, New York.

The differences in liver-related mortality between Medicaid expansion and nonexpansion states was particularly pronounced in people of Asian background, in Whites, and in African Americans, he said in an oral abstract presentation during the virtual annual meeting of the American Association for the Study of Liver Diseases.

“The expansion of government health care programs such as Medicaid may improve liver-related mortality and liver transplant waitlist placement,” he said.

The implementation of the ACA, also known as Obamacare, resulted in “a pretty dramatic increase in the number of Americans with health insurance today, and there’s a lot of literature out there looking at a variety of domains throughout health care that have found that Medicaid expansion increased access and decreased disparities in care,” he added.

For example, a report published in 2019 by the nonpartisan National Bureau of Economic Research Priorities showed a significant reduction in disease-related deaths in Americans aged 55-64 in Medicaid expansion states compared with nonexpansion states.

In addition as previously reported, before Medicaid expansion African Americans were 4.8% less likely than were Whites to receive timely cancer treatment, defined as treatment starting within 30 days of diagnosis of an advanced or metastatic solid tumor. After Medicaid expansion, however, the difference between the racial groups had dwindled to just 0.8% and was no longer statistically significant.

“However, specifically in the realm of liver transplantation and liver disease, there’s very limited literature showing any sort of significant impact on care resulting from Medicaid expansion,” Dr. Wahid said.
 

Listing-to-death ratio

To test their hypothesis that Medicaid expansion decreased racial disparities and improved liver-related deaths and transplant waitlist placement, Dr. Wahid and colleagues compared liver-related deaths and liver transplants listings between Medicaid expansion and nonexpansion states in the 5 years before expansion (2009-2013) and in the 5 years after expansion (2014-2018). They excluded all states without transplant centers as well as patients younger than 25 or older than 64, who were likely to be covered by other types of insurance.

They obtained data for listing from the United Network for Organ Sharing (UNOS) and on end-stage liver disease from the Centers for Disease Control and Prevention’s WONDER database.

They also used a novel measure called the listing-to-death ratio (LDR), a surrogate endpoint for waitlist placement calculated as the ratio of listings for liver transplantation relative to the number of deaths from liver disease, with a higher LDR score corresponding to improved waitlist placement.

They found that throughout the entire study period, Medicaid expansion states had lower liver-related deaths, higher liver transplant listings, and higher LDR.

Using joinpoint regression to examine changes at a specific time point, the investigators determined that the annual percentage change in liver-related deaths increased in both nonexpansion states (mean 4.3%) and expansion states (3.0%) before 2014. However, beginning around 2015, liver-related deaths began to decline in expansion states by a mean of –0.6%, while they continued on an upward trajectory in the nonexpansion states, albeit at a somewhat slower pace (mean APC 2% from 2014 through 2018).

Among all racial and ethnic groups (Whites, African Americans, Hispanics, and Asians) liver-related deaths increased from 2014 to 2018 in nonexpansion states, with the highest annual percentage change in Asians, at slightly more than 8%.

In contrast, among Asians in the expansion states, liver-related deaths over the same period increased by less than 1%, and in both Whites and African Americans liver-related deaths declined.

In addition, starting in 2015, the annual percent change in LDR increased only in expansion states primarily because of fewer end-stage liver disease deaths (the denominator in the LDR equation) rather than increased listings (the numerator).
 

 

 

‘No-brainer’

A gastroenterologist who was not involved in the study said that there are two key points in favor of the study.

“The obvious message is that transplant is costly, and patients need to be insured to get a liver transplant, because nobody is paying for this out of pocket. So if more candidates are insured that will reduce disparities and improve access to liver transplant for those who need it,” said Elliot Benjamin Tapper, MD, of the University of Michigan, Ann Arbor.

“It’s a no-brainer that the lack of insurance accessibility for the most vulnerable people in the United States meant that they were dying of cirrhosis instead of being transplanted,” he said in an interview.

He also commended the authors on their use of population-based data to identify outcomes.

“We know how many people are listed for liver transplant, but we don’t know how many people could have been listed. We know how many people are transplanted, but we don’t know how many people with decompensated cirrhosis should have been given that chance. We lacked that denominator,” he said.

“The innovation that makes this particular paper worthwhile is that in the absence of that denominator, they were able to construct it, so we can know from other data sources distinct from the waitlist rolls how many people are dying of cirrhosis,” he added.

No study funding source was reported. Dr. Wahid and Dr. Tapper reported no conflicts of interest.

So if more candidates are insured that will reduce disparities and improve access to liver transplant for those who need it,” said Elliot Benjamin Tapper, MD, of the University of Michigan, Ann Arbor.

“It’s a no-brainer that the lack of insurance accessibility for the most vulnerable people in the United States meant that they were dying of cirrhosis instead of being transplanted,” he said in an interview.

He also commended the authors on their use of population-based data to identify outcomes.

“We know how many people are listed for liver transplant, but we don’t know how many people could have been listed. We know how many people are transplanted, but we don’t know how many people with decompensated cirrhosis should have been given that chance. We lacked that denominator,” he said.

“The innovation that makes this particular paper worthwhile is that in the absence of that denominator, they were able to construct it, so we can know from other data sources distinct from the waitlist rolls how many people are dying of cirrhosis,” he added.

No study funding source was reported. Dr. Wahid and Dr. Tapper reported no conflicts of interest.

Liver injury linked to COVID-19–related coagulopathy

Article Type

Thu, 08/26/2021 - 15:55

 

There is a link between liver injury and a tendency toward excessive clotting in patients with COVID-19, and the organ’s own blood vessels could be responsible, new research shows.

Cells that line the liver’s blood vessels produce high levels of factor VIII, a coagulation factor, when they are exposed to interleukin-6, an inflammatory molecule associated with COVID-19.

These findings “center the liver in global coagulopathy of COVID-19 and define a mechanism for increased coagulation factor levels that may be treatment targets,” said investigator Matthew McConnell, MD, from the Yale University, New Haven, Conn.

The effect of IL-6 on the liver sinusoidal endothelial cells lining the liver blood vessels creates a prothrombotic environment that includes the release of factor VIII, said Dr. McConnell, who presented the results at the virtual annual meeting of the American Association for the Study of Liver Diseases.

These associations offer insights into why COVID-19 patients with underlying liver disease can experience “devastating complications” related to improper blood vessel function in the organ, he added.

For their study, Dr. McConnell and colleagues analyzed data on ALT and hypercoagulability from 68 adults treated at the Yale–New Haven Hospital. The liver and coagulation tests were administered within 5 days of each other.

The team set the ALT cutoff for liver injury at three times the upper limit of normal. Patients with two or more parameters indicating excessive clotting were considered to have a hypercoagulable profile, which Dr. McConnell called “a signature clinical finding of COVID-19 infection.”

Patients with high levels of ALT also experienced elevations in clotting-related factors, such as fibrinogen levels and the activity of factor VIII and factor II. Furthermore, liver injury was significantly associated with hypercoagulability (P < .05).

Because COVID-19 is linked to the proinflammatory IL-6, the investigators examined how this cytokine and its receptor affect human liver sinusoidal cells. Cells exposed to IL-6 and its receptor pumped out factor VIII at levels that were significantly higher than in unexposed cells (P < .01). Exposed cells also produced significantly more von Willebrand factor (P < .05), another prothrombotic molecule, and showed increased expression of genes that induce the expression of factor VIII.

“As we learn more about COVID-19, we find that it is as much a coagulatory as a respiratory disease,” said Tien Dong, MD, PhD, from the University of California, Los Angeles, who was not involved in the study.

These findings are in line with a lot of other COVID-19-related research that suggests a link between hepatocyte injury and clotting disorders, he added.

One important factor is existing liver disease, said Dr. Dong. “If you have COVID-19 on top of that, you’re probably at risk of developing acute liver injury from the infection itself.”

That said, it’s still a good idea to check liver function in patients with COVID-19 and no known liver disease, he advised. Staying on top of these measures will keep the odds of long-term problems “a lot lower.”

There is utility in the findings beyond COVID-19, said Dr. McConnell. They provide “insights into complications of critical illness, in general, in the liver blood vessels” of patients with underlying liver disease.

Dr. McConnell and Dr. Dong have disclosed no relevant financial relationships.

One-third of critical illness survivors emerge from ICU with functional deterioration

Article Type
Changed
Thu, 08/26/2021 - 15:55

More patients are surviving critical illnesses requiring ICU care but many emerge with physical debility that may or may not eventually resolve.

Over the past decade, functional status deterioration after critical illness has become more common and of greater magnitude, despite concurrent efforts to reduce post–intensive care syndrome, based on a retrospective analysis of more than 100,000 patients.

Almost one-third of patients who survived nonsurgical ICU admission had evidence of functional status decline, reported lead author Nicholas E. Ingraham, MD, of the University of Minnesota, Minneapolis, and colleagues.

“Increasing capacity and decreasing mortality have created an evolving and diverse population of ICU survivors,” the investigators wrote in Critical Care Medicine. “Today’s survivors of critical illness are increasingly burdened by extensive physical and psychological comorbidities, often resulting in reduced quality of life.”

To determine trends in post–intensive care syndrome from 2008 to 2016, Dr. Ingraham and colleagues analyzed data from the Cerner Acute Physiology and Chronic Health Evaluation outcomes database, a national prospective cohort. Out of 202,786 adult patients admitted to the ICU, 129,917 were eligible for the study. Patients were excluded because of surgical admission, death, lack of functional status documentation, or inadequate hospital size or duration of participation. The final dataset had a median age of 63 years, with a slight predominance of male patients (54.0%). Most patients (80.9%) were White.

The primary outcome was defined as presence or absence of functional status deterioration, based on functional status at admission versus time of discharge. The secondary outcome was magnitude of deterioration over time.

The analysis, which controlled for age and severity of illness, revealed concerning trends for both outcomes.

Across the entire cohort 38,116 patients (29.3%) had functional status deterioration, with a 15% increase in prevalence over the course of the decade that spanned all disease categories (prevalence rate ratio, 1.15; 95% confidence interval, 1.13-1.17; P < .001). The magnitude of functional status decline also increased by 4% (odds ratio, 1.04; P < .001), with all but nonsurgical trauma patients showing greater deterioration over time.

“However, despite the decreasing magnitude of functional status deterioration in nonsurgical trauma, many admission diagnoses in this category remain in the top quartile of higher risk for functional status deterioration,” the investigators noted.

Functional status decline was most common among patients with head and polytrauma (OR, 3.39), followed closely by chest and spine trauma (OR, 3.38), and spine trauma (OR, 3.19). The top quartile of categories for prevalence of deterioration included nonsurgical trauma, neurologic, pulmonary, and gastrointestinal diseases.

Functional status decline was least common among patients diagnosed with diabetic ketoacidosis (OR, 0.27) or asthma (OR, 0.35).

“We believe our study provides important information that can be used in beginning to identify patients at high risk of functional status decline,” the investigators concluded. “Improving the identification of these patients and targeting appropriate interventions to mitigate this decline will be important directions for future studies in this area.”

According to David L. Bowton, MD, FCCP, professor emeritus, section on critical care, Wake Forest Baptist Health, Winston-Salem, N.C., the findings show just how common functional decline is after critical illness, and may actually underestimate prevalence.

“Because the authors employed a course evaluation tool employing only three categories of ability/disability and abstracted the level of disability from the medical record, they likely underestimated the frequency of clinically important, though not detected, disability at the time of hospital discharge,” Dr. Bowton said. “The study did not address cognitive impairment which can be detected in half of patients at 3 months following critical illness, and which significantly affects patients’ quality of life (Am J Respir Crit Care Med. 2020;202[2]:193-201).”

Dr. Bowton suggested that evidence-based methods of preventing post–intensive care syndrome are limited.

“Current efforts to improve post-ICU functional and cognitive outcomes suffer from the lack of proven effective interventions (Crit Care Med. 2019;47[11]:1607-18),” he said. “Observational data indicates that compliance with the ABCDEF bundle decreases the duration and incidence of delirium, ICU length of stay, duration of mechanical ventilation, and mortality (Crit Care Med. 2019;47[1]:3-14). However, the implications of these improvements on postdischarge functional outcomes are unknown as area the relative importance of individual elements of the bundle. Early mobility and patient and family diaries appear to improve functional status at discharge and postdischarge anxiety and depression, though the evidence supporting this is thin.”

Appropriate intervention may be especially challenging during the COVID-19 pandemic, he added.

“The impact of COVID on ICU staffing adequacy and stress is significant and the impact on quality bundle compliance and the availability of support services is currently not clear, but likely to be detrimental, especially to support services such as physical therapy that are already commonly understaffed,” Dr. Bowton said.

The study was supported by grants from the University of Minnesota’s Critical Care Research and Programmatic Development Program; the National Heart, Lung, and Blood Institute; and the University of Minnesota Clinical and Translational Science via the National Center for Advancing Translational Sciences. The investigators reported financial relationships with no other relevant organizations. Dr. Bowton reported no conflicts of interest.

Boston Scientific bails on Lotus Edge aortic valve system

Article Type
Changed
Wed, 11/18/2020 - 11:07

Boston Scientific said it is voluntarily recalling all unused inventory of the Lotus Edge transcatheter aortic valve replacement system effective immediately.

In making the announcement today, Boston Scientific chair and CEO Mike Mahoney said the company has been increasingly challenged by the intricacies of the delivery system required to allow physicians to fully reposition and recapture the valve – key features of the system.

“The complexity of the delivery system, manufacturing challenges, the continued need for further technical enhancements, and current market adoption rates led us to the difficult decision to stop investing in the Lotus Edge platform,” Mr. Mahoney said.

Instead, the company will focus on the ACURATE neo2 aortic valve system, the Sentinel cerebral embolic protection device, and other high-growth areas, he noted.

The decision is expected to result in a $225 million to $300 million pretax charge, with $100 million to $150 million of these charges to impact the company’s adjusted results.



The Lotus device was approved in the United States in April 2019 for use in patients with severe aortic stenosis at high surgical risk based on the REPRISE 3 trial.

The Lotus Edge valve was approved in Europe in 2016, but final testing and rollout of the valve in the United States were delayed following a 2017 global recall of all Lotus valves because of reports of premature release of a pin connecting the valve to the delivery system.

Issues with the delivery system led to other Lotus valve recalls in both 2016 and 2014.

“Given the additional time and investment required to develop and reintroduce an enhanced delivery system, the company has chosen to retire the entire Lotus product platform immediately. All related commercial, clinical, research & development and manufacturing activities will also cease,” the statement said.

There is no safety issue for patients who currently have an implanted Lotus Edge valve, the company said.

The decision is expected to result in a $225 million to $300 million pretax charge, with $100 million to $150 million of these charges to impact the company’s adjusted results.



The Lotus device was approved in the United States in April 2019 for use in patients with severe aortic stenosis at high surgical risk based on the REPRISE 3 trial.

The Lotus Edge valve was approved in Europe in 2016, but final testing and rollout of the valve in the United States were delayed following a 2017 global recall of all Lotus valves because of reports of premature release of a pin connecting the valve to the delivery system.

Issues with the delivery system led to other Lotus valve recalls in both 2016 and 2014.

“Given the additional time and investment required to develop and reintroduce an enhanced delivery system, the company has chosen to retire the entire Lotus product platform immediately. All related commercial, clinical, research & development and manufacturing activities will also cease,” the statement said.

There is no safety issue for patients who currently have an implanted Lotus Edge valve, the company said.

COVID-19 burdens follow patients after discharge

Article Type

Thu, 08/26/2021 - 15:55

COVID-19 patients who survive their hospitalization don’t leave the disease behind upon discharge, as a significant percentage died within 60 days of discharge, with an ICU admission heightening the risk, according to an observational study of 38 Michigan hospitals. What’s more, many of them were burdened with health and emotional challenges ranging from hospital readmission to job loss and financial problems.

“These data confirm that the toll of COVID-19 extends well beyond hospitalization, a finding consistent with long-term sequelae from sepsis and other severe respiratory viral illnesses,” wrote lead author Vineet Chopra, MBBS, of the University of Michigan, Ann Arbor, and colleagues (Ann Intern Med. 2020 Nov 11: doi: 10.7326/M20-5661)

The researchers found that 29.2% of all patients hospitalized for COVID-19 from March 16 to July 1 died. The observational cohort study included 1,648 COVID-19 patients hospitalized at 38 Michigan hospitals participating in a statewide collaborative.

The bulk of those deaths occurred during hospitalization: 24.2% of patients (n = 398). Of the 1,250 patients discharged, 78% (n = 975) went home and 12.6% (n = 158) went to a skilled nursing facility, with the remainder unaccounted for. Within 60 days of discharge, 6.7% (n = 84) of hospitalized survivors had died and 15.2% (n = 189) were readmitted. The researchers gathered 60-day postdischarge data via a telephone survey, contacting 41.8% (n = 488) of discharged patients.

Outcomes were even worse for discharged patients who spent time in the ICU. The death rate among this group was 10.4% (17 of 165) after discharge. That resulted in an overall study death rate of 63.5% (n = 257) for the 405 patients who were in the ICU.

While the study data were in the first wave of the novel coronavirus, the findings have relevance today, said Mary Jo Farmer, MD, PhD, FCCP, directory of pulmonary hypertension services at Baystate Health in Springfield, Mass.

Dr. Mary Jo Farmer

“This is the best information we have to date,” she said. “We have to continue to have an open mind and expect that this information may change as the virus possibly mutates as it spreads, and we should continue doing these types of outcomes studies at 90 days, 120 days, etc.”

The median age of study patients was 62, with a range of 50-72. The three leading comorbidities among discharged patients were hypertension (n = 800, 64%), diabetes (34.9%, n = 436), and cardiovascular disease (24.1%, n = 301).

Poor postdischarge outcomes weren’t limited to mortality and readmission. Almost 19% (n = 92) reported new or worsening cardiopulmonary symptoms such as cough and dyspnea, 13.3% had a persistent loss of taste or smell, and 12% (n = 58) reported more difficulty with daily living tasks.

The after-effects were not only physical. Nearly half of discharged patients (48.7%, n = 238) reported emotional effects and almost 6% (n = 28) sought mental health care. Among the 40% (n = 195) employed before they were hospitalized, 36% (n = 78) couldn’t return to work because of health issues or layoffs. Sixty percent (n = 117) of the pre-employed discharged patients did return to work, but 25% (n = 30) did so with reduced hours or modified job duties because of health problems.

Financial problems were also a burden. More than a third, 36.7% (n = 179), reported some financial impact from their hospitalization. About 10% (n = 47) said they used most or all of their savings, and 7% (n = 35) said they resorted to rationing necessities such as food or medications.

The researchers noted that one in five patients had no primary care follow-up at 2 months post discharge. “Collectively, these findings suggest that better models to support COVID-19 survivors are necessary,” said Dr. Chopra and colleagues.

The postdischarge course for patients involves two humps, said Sachin Gupta, MD, FCCP a pulmonary and critical care specialist at Alameda Health System in Oakland, Calif.: Getting over the hospitalization itself and the recovery phase. “As you look at the median age of the survivors, elderly patients who survive a hospital stay are still going to have a period of recovery, and like any viral illness that leads to someone being hospitalized, when you have an elderly patient with comorbidities, not all of them can make it over that final hump.”

Dr. Sachin Gupta


He echoed the study authors’ call for better postdischarge support for COVID-19 patients. “There’s typically, although not at every hospital, a one-size-fits-all discharge planning process,” Dr. Gupta said. “For older patients, particularly with comorbid conditions, close follow-up after discharge is important.”

Dr. Farmer noted that one challenge in discharge support may be a matter of personnel. “The providers of this care might be fearful of patients who have had COVID-19 – Do the patients remain contagious? What if symptoms of COVID-19 return such as dry cough, fever? – and of contracting the disease themselves,” she said. 

The findings regarding the emotional status of discharged patients should factor into discharge planning, she added. “Providers of posthospital care need to be educated in the emotional impact of this disease (e.g., the patients may feel ostracized or that no one wants to be around them) to assist in their recovery.”  

Dr. Chopra and Dr. Farmer have no financial relationships to disclose. Dr. Gupta is an employee and shareholder of Genentech.

Pediatric dermatology: Reflecting on 50 years

Article Type
Changed
Tue, 06/01/2021 - 17:45

As part of the 50th anniversary of Dermatology News, it is intriguing to think about where a time machine journey 5 decades back would find the field of pediatric dermatology, and to assess the changes in the specialty during the time that Dermatology News (operating then as “Skin & Allergy News”) has been reporting on innovations and changes in the practice of dermatology.

Society for Pediatric Dermatology
Participants at the second meeting of the International Society of Pediatric Dermatology in Chicago, August 1979.

So, starting in 1970, we would find that pediatric dermatology did not exist as an organized specialty. It was not until 3 years later, in October 1973 in Mexico City, that the first international symposium on Pediatric Dermatology was held, and the International Society for Pediatric Dermatology was founded. I reached out to Andrew Margileth, MD, 100 years old this past July, and still active voluntary faculty in pediatric dermatology at the University of Miami, to help me “reach back” to those days. Dr. Margileth commented on how the first symposium was “brilliantly orchestrated by Ramon Ruiz-Maldonado,” from the National Institute of Paediatrics in Mexico, and that it was his “Aha moment for future practice!” That meeting spurred discussions on the development of the Society for Pediatric Dermatology the next year, with Alvin Jacobs, MD; Samuel Weinberg, MD; Nancy Esterly, MD; Sidney Hurwitz, MD; William Weston, MD; and Coleman Jacobson, MD, as some of the initial “founding mothers and fathers,” and the society was officially established in 1975.

The field of pediatric dermatology was fairly “infantile” 50 years ago, with few practitioners. But the early leaders in the field recognized that up to 30% of pediatric primary care visits included skin problems, and that there was limited training for dermatologists, as well as pediatricians, about skin diseases in children. There were clearly clinical and educational needs to establish a subspecialty of pediatric dermatology, and over the next 1-2 decades, the field expanded. The journal Pediatric Dermatology was established (in 1982), the Section on Dermatology was established by the American Academy of Pediatrics (in 1986), and fellowship programs were launched at select academic centers. And it was 30 years into our timeline before the formal subspecialty of pediatric dermatology was established through the American Board of Dermatology (2000).

The field of pediatric dermatology has evolved and matured rapidly. Standard reference textbooks have been developed in the United States and around the world (and of course, online). Pediatric dermatology is an essential part of the core curriculum for dermatologist trainees. Organizations promoting pediatric research have developed to influence basic, translational, and clinical research in conditions in neonates through adolescents, such as the Pediatric Dermatology Research Alliance (PeDRA). And meetings throughout the world now feature pediatric dermatology sessions and help to spread the advances in the diagnosis and management of pediatric skin disorders.




 

The practice of pediatric dermatology: How has it changed?

It is beyond the scope of this article to try to comprehensively review all of the changes in pediatric dermatology practice. But review of the evolution of a few disease states (choices influenced by my discussions with my 100-year old history guide, Dr. Margileth) displays examples of where we have been, and where we are going in our next 5, 10, or 50 years.

Hemangiomas and vascular malformations

Some of the first natural history studies on hemangiomas were done in the early 1960s, establishing that standard cutaneous hemangiomas had a typical clinical course of fairly rapid growth, plateau, and involution over time. Of interest, the hallmark article’s first author was Dr. Margileth, published in 1965 in JAMA!.This was still at a time when the identification of hemangiomas of infancy (or “HOI” as we say in the trade) was confused with vascular malformations, and no one had recognized the distinct variant tumors such as rapidly involuting and noninvoluting congenital hemangiomas (RICHs or NICHs), tufted angiomas, or hemangioendotheliomas. PHACE syndrome was not yet described (that was done in 1996 by Ilona Frieden, MD, and colleagues). And for a time, hemangiomas were treated with x-rays, before the negative impact of such radiation was acknowledged. It seems that, as a consequence of the use of x-ray therapy and as a backlash from the radiation therapy side effects and potential toxicities, even deforming and functionally significant lesions were “followed clinically” for natural involution, with a sensibility that doing nothing might be better than doing the wrong thing.

Over the next 15 years, the recognition of functionally significant hemangiomas, deformation associated with their proliferation, and the recognition of PHACE syndrome made hemangiomas of infancy an area of concern, with systemic steroids and occasionally chemotherapeutic agents (such as vincristine) being used for problematic lesions.

It has now been 12 years since the work of Christine Léauté-Labrèze, MD, et al., from the University of Bordeaux (France), led to the breakthrough of propranolol for hemangioma treatment, profoundly changing hemangioma management to an incredibly effective medical therapy extensively studied, tested in formal clinical trials, and approved by regulatory authorities. And how intriguing that this was pursued after the chance (but skilled) observation that a child who developed hypertension as a side effect of systemic steroids for nasal hemangioma treatment was prescribed propranolol for the hypertension and had his nasal hemangioma rapidly shrink, with a response superior and much quicker than that to corticosteroids.

The evolution of management of hemangiomas has another story within it, that of collaborative research. The Hemangioma Investigator Group was formed to take a collaborative approach to characterize and study hemangiomas and related tumors. Beginning with energetic, insightful pediatric dermatologists and little funding, they changed our knowledge base of how hemangiomas present, the risk factors for their development, and the characteristics and multiple organ findings associated with PHACE and other syndromic hemangiomas. Our knowledge of these lesions is now evidence based and broad, and the impact on care tremendous! The HIG has also influenced the practice of pediatricians and other specialists, including otorhinolaryngologists, hematologist/oncologists, and surgeons, is partnering with advocacy groups to support patients and families, and is helping guide patients and families to contribute to ongoing research.

Vascular malformations (VM) reflect an incredible change in our understanding of the developmental pathways and pathophysiology of blood vessel tumors, and, in fact, birthmarks other than vascular lesions! First, important work separated out hemangiomas of infancy and hemangiomalike tumors from vascular malformations, with the thought being that hemangiomas had a rapid growth phase, often arising from lesions that were minimally evident or not evident at birth, unlike malformations, which were “programing errors,” all present at birth and expected to be fairly static with proportionate growth over a lifetime. Approaches to vascular malformations were limited to sclerotherapy, laser, and/or surgery. While this general schema of classification is still useful, our sense of the “why and how” of vascular malformations is remarkably different. Vascular malformations – still usefully subdivided into capillary, lymphatic, venous arteriovenous, or mixed malformations – are mostly associated with inherited or somatic mutations. Mutations are most commonly found in two signal pathways: RAS/MAPK/ERK and PI3K/AKT/mTOR pathways, with specific sets of mutations seen in both localized and multifocal lesions, with or without overgrowth or other systemic anomalies. The discovery of specific mutations has led to the possibility of small-molecule inhibitors, many already existing as anticancer drugs, being utilized as targeted therapies for VM.

And similar advances in understanding of other birthmarks, with or without syndromic features, are being made steadily. The mutations in congenital melanocytic nevi, epidermal nevi, acquired tumors (pilomatricomas), and other lesions, along with steady epidemiologic, translational, and clinical work, evolves our knowledge and potential therapies.

 

 

Inflammatory skin disorders: Acne, psoriasis, and atopic dermatitis

The care of pediatric inflammatory skin disorders has evolved, but more slowly for some diseases than others. Acne vulgaris is now recognized as much more common under age 12 than previously, presumably reflecting earlier pubertal changes in our preteens. Over the past 30 years, therapy has evolved with the use of topical retinoids (still underused by pediatricians, considered a “practice gap”), hormonal therapy with combined oral contraceptives, and oral isotretinoin, a powerful but highly effective systemic agent for severe and refractory acne. Specific pediatric guidelines came much later, with expert recommendations formulated by the American Acne and Rosacea Society and endorsed by the American Academy of Pediatrics in 2013. Over the past few years, there has been a push by experts for more judicious use of antibiotics for acne (oral and topical) to minimize the emergence of bacterial resistance. There are unanswered questions as we evolve our care: How will the new topical antiandrogens be used? Will spironolactone become part of hormonal therapy under age 18? Will the insights on certain strains of Cutibacterium acnes being associated with worse acne translate to microbiome or vaccine-based strategies?

Pediatric psoriasis has suffered, being “behind in the revolution” of biologic agents because of delayed approval of any biologic agent for treatment of pediatric psoriasis in the United States until just a few years ago, and lags behind Europe and elsewhere in the world by almost a decade. Only this year have we expanded beyond one biologic agent approved for under age 12 and two for ages 12 and older, with other approvals expected including interleukin (IL)-17 and IL-23 agents. Adult psoriasis has been recognized to be associated with a broad set of comorbidities, including obesity and early heart disease, and there is now research on how children are at risk as well, with new recommendations on how to screen children with psoriasis, supplied first by PeDRA and then in the new American Academy of Dermatology-National Psoriasis Foundation pediatric psoriasis guidelines .



Pediatric atopic dermatitis (AD) is in its early years of revolution. In the 50-year period of our thought experiment, AD has increased in prevalence from 5% or less of the pediatric population to 10%-15%. Treatment of most individuals has remained the same over the decades: Good skin care, frequent moisturizers, topical corticosteroids for flares, and management of infection if noted. The topical calcineurin inhibitors (TCIs) broadened the therapeutic approach when introduced in 2000 and 2001, but the boxed warning resulted in some practitioners minimizing their use of these useful agents. But newer studies are markedly reassuring about their safe use in children.

Steroid phobia, as well as concerns about potential side effects of the TCIs, has resulted in undertreatment of childhood AD. It is quite common to see multiple children during pediatric dermatology office hours with poorly controlled eczema, high body-surface areas of eczema, compromised sleep, secondary infections, and anxiety and depression, especially in our moderate to severe adolescents. The field is “hot” with new topical and systemic agents, including our few years’ experience with topical crisaborole, a phosphodiesterase (PDE)-4 inhibitor; and dupilumab, an IL-4-alpha blocker – the first biologic agent approved for AD and the first systemic agent (other than oral corticosteroids), just extended from 12 years to 6 years of age! As dupilumab gets studied for younger children, other biologics (including IL-13 and IL-31 blockers) are undertaking pediatric and/or adolescent trials, oral and topical JAK inhibitors are including adolescents in core clinical trials, and other novel topical agents are under study, including an aryl-hydrocarbon receptor–modulating agent and other PDE-4 inhibitors.

 

 

Procedural pediatric dermatology: From liquid nitrogen to laser, surgery, and multimodal skin care

The first generation of pediatric dermatologists were considered medical dermatologist specialists. The care of the conditions discussed above, as well as genodermatoses, diagnostic dilemmas, and management of dermatologic manifestations of systemic disease and other conditions, was the “bread and butter” of pediatric dermatology care. When I was in training, my mentor Paul Honig, MD, at the Children’s Hospital of Philadelphia had a procedure half-day each week, where he would care for a few patients who needed liquid nitrogen therapy for warts, or who needed biopsies. It was uncommon to have a large procedural/surgical part of pediatric dermatology practice. But this is now a routine part of many specialists in the field. How did this change occur?

Dr. Lawrence F. Eichenfield

The fundamental shift began to occur with the introduction of the pulsed dye laser for treatment of port-wine birthmarks in children with minimal scarring, and a seminal article published in the New England Journal of Medicine in 1989. Vascular lesions including port-wine stains were common, and pediatric dermatologists managed these patients for both diagnosis and medical management. Also, dermatology residencies at this time offered training in cutaneous surgery, excisions (including Mohs surgery) and repairs, and trainees in pediatric dermatology were “trained up” to high levels of expertise. As lasers were incorporated into dermatology residency work and practices, pediatric dermatologists developed the exposure and skill to do this work. An added advantage was having the knowledge of how to handle children and adolescents in an age-appropriate manner, with consideration of methods to minimize the pain and anxiety of procedures. Within a few years, pediatric dermatologists were at the forefront of the use of topical anesthetics (EMLA and liposomal lidocaine) and had general anesthesia privileges for laser and excisional surgery.

So while pediatric dermatologists still do “small procedures” every hour in most practices (cryotherapy for warts, cantharidin for molluscum, shave and punch biopsies), a subset now have extensive procedural practices, which in recent years has extended to pigment lesion lasers (to treat nevus of Ota, for example), hair laser, and combinations of lasers, including fractionated CO2 technology, to treat hypertrophic, constrictive and/or deforming scars.
 

The future

What will pediatric dermatology be like in 10, 20, or 50 years?

I have not yet discussed some of the most challenging diseases in our field, including epidermolysis bullosa, ichthyosis, and neurocutaneous disorders and other genetic skin disorders that have an incredible impact on the lives of affected children and their families, with incredible morbidity and with many conditions that shorten lifespans. But these are the conditions where “the future is happening now,” and we are looking forward to our new gene therapy techniques helping to transform our care.

And other aspects of practice? Will we be doing a large percentage of practice over the phone (or whatever devices we have then – remember, the first iPhone was only released 13 years ago)?

Will our patients be using their own imaging systems to evaluate their nevi and skin growths, and perhaps to diagnose and manage their rashes?

Will we have prevented our inflammatory skin disorders, or “turned them off” in early life with aggressive therapy in infantile life?

I project only that all of us in dermatology will still be a resource to our pediatric patients, from neonate through young adult, through our work of preventing, caring, healing and minimizing disease impact, and hopefully enjoying the pleasures of seeing our patients healthfully develop and evolve! As will our field.

As part of the 50th anniversary of Dermatology News, it is intriguing to think about where a time machine journey 5 decades back would find the field of pediatric dermatology, and to assess the changes in the specialty during the time that Dermatology News (operating then as “Skin & Allergy News”) has been reporting on innovations and changes in the practice of dermatology.

Society for Pediatric Dermatology
Participants at the second meeting of the International Society of Pediatric Dermatology in Chicago, August 1979.

So, starting in 1970, we would find that pediatric dermatology did not exist as an organized specialty. It was not until 3 years later, in October 1973 in Mexico City, that the first international symposium on Pediatric Dermatology was held, and the International Society for Pediatric Dermatology was founded. I reached out to Andrew Margileth, MD, 100 years old this past July, and still active voluntary faculty in pediatric dermatology at the University of Miami, to help me “reach back” to those days. Dr. Margileth commented on how the first symposium was “brilliantly orchestrated by Ramon Ruiz-Maldonado,” from the National Institute of Paediatrics in Mexico, and that it was his “Aha moment for future practice!” That meeting spurred discussions on the development of the Society for Pediatric Dermatology the next year, with Alvin Jacobs, MD; Samuel Weinberg, MD; Nancy Esterly, MD; Sidney Hurwitz, MD; William Weston, MD; and Coleman Jacobson, MD, as some of the initial “founding mothers and fathers,” and the society was officially established in 1975.

The field of pediatric dermatology was fairly “infantile” 50 years ago, with few practitioners. But the early leaders in the field recognized that up to 30% of pediatric primary care visits included skin problems, and that there was limited training for dermatologists, as well as pediatricians, about skin diseases in children. There were clearly clinical and educational needs to establish a subspecialty of pediatric dermatology, and over the next 1-2 decades, the field expanded. The journal Pediatric Dermatology was established (in 1982), the Section on Dermatology was established by the American Academy of Pediatrics (in 1986), and fellowship programs were launched at select academic centers. And it was 30 years into our timeline before the formal subspecialty of pediatric dermatology was established through the American Board of Dermatology (2000).

The field of pediatric dermatology has evolved and matured rapidly. Standard reference textbooks have been developed in the United States and around the world (and of course, online). Pediatric dermatology is an essential part of the core curriculum for dermatologist trainees. Organizations promoting pediatric research have developed to influence basic, translational, and clinical research in conditions in neonates through adolescents, such as the Pediatric Dermatology Research Alliance (PeDRA). And meetings throughout the world now feature pediatric dermatology sessions and help to spread the advances in the diagnosis and management of pediatric skin disorders.




 

The practice of pediatric dermatology: How has it changed?

It is beyond the scope of this article to try to comprehensively review all of the changes in pediatric dermatology practice. But review of the evolution of a few disease states (choices influenced by my discussions with my 100-year old history guide, Dr. Margileth) displays examples of where we have been, and where we are going in our next 5, 10, or 50 years.

Hemangiomas and vascular malformations

Some of the first natural history studies on hemangiomas were done in the early 1960s, establishing that standard cutaneous hemangiomas had a typical clinical course of fairly rapid growth, plateau, and involution over time. Of interest, the hallmark article’s first author was Dr. Margileth, published in 1965 in JAMA!.This was still at a time when the identification of hemangiomas of infancy (or “HOI” as we say in the trade) was confused with vascular malformations, and no one had recognized the distinct variant tumors such as rapidly involuting and noninvoluting congenital hemangiomas (RICHs or NICHs), tufted angiomas, or hemangioendotheliomas. PHACE syndrome was not yet described (that was done in 1996 by Ilona Frieden, MD, and colleagues). And for a time, hemangiomas were treated with x-rays, before the negative impact of such radiation was acknowledged. It seems that, as a consequence of the use of x-ray therapy and as a backlash from the radiation therapy side effects and potential toxicities, even deforming and functionally significant lesions were “followed clinically” for natural involution, with a sensibility that doing nothing might be better than doing the wrong thing.

Over the next 15 years, the recognition of functionally significant hemangiomas, deformation associated with their proliferation, and the recognition of PHACE syndrome made hemangiomas of infancy an area of concern, with systemic steroids and occasionally chemotherapeutic agents (such as vincristine) being used for problematic lesions.

It has now been 12 years since the work of Christine Léauté-Labrèze, MD, et al., from the University of Bordeaux (France), led to the breakthrough of propranolol for hemangioma treatment, profoundly changing hemangioma management to an incredibly effective medical therapy extensively studied, tested in formal clinical trials, and approved by regulatory authorities. And how intriguing that this was pursued after the chance (but skilled) observation that a child who developed hypertension as a side effect of systemic steroids for nasal hemangioma treatment was prescribed propranolol for the hypertension and had his nasal hemangioma rapidly shrink, with a response superior and much quicker than that to corticosteroids.

The evolution of management of hemangiomas has another story within it, that of collaborative research. The Hemangioma Investigator Group was formed to take a collaborative approach to characterize and study hemangiomas and related tumors. Beginning with energetic, insightful pediatric dermatologists and little funding, they changed our knowledge base of how hemangiomas present, the risk factors for their development, and the characteristics and multiple organ findings associated with PHACE and other syndromic hemangiomas. Our knowledge of these lesions is now evidence based and broad, and the impact on care tremendous! The HIG has also influenced the practice of pediatricians and other specialists, including otorhinolaryngologists, hematologist/oncologists, and surgeons, is partnering with advocacy groups to support patients and families, and is helping guide patients and families to contribute to ongoing research.

Vascular malformations (VM) reflect an incredible change in our understanding of the developmental pathways and pathophysiology of blood vessel tumors, and, in fact, birthmarks other than vascular lesions! First, important work separated out hemangiomas of infancy and hemangiomalike tumors from vascular malformations, with the thought being that hemangiomas had a rapid growth phase, often arising from lesions that were minimally evident or not evident at birth, unlike malformations, which were “programing errors,” all present at birth and expected to be fairly static with proportionate growth over a lifetime. Approaches to vascular malformations were limited to sclerotherapy, laser, and/or surgery. While this general schema of classification is still useful, our sense of the “why and how” of vascular malformations is remarkably different. Vascular malformations – still usefully subdivided into capillary, lymphatic, venous arteriovenous, or mixed malformations – are mostly associated with inherited or somatic mutations. Mutations are most commonly found in two signal pathways: RAS/MAPK/ERK and PI3K/AKT/mTOR pathways, with specific sets of mutations seen in both localized and multifocal lesions, with or without overgrowth or other systemic anomalies. The discovery of specific mutations has led to the possibility of small-molecule inhibitors, many already existing as anticancer drugs, being utilized as targeted therapies for VM.

And similar advances in understanding of other birthmarks, with or without syndromic features, are being made steadily. The mutations in congenital melanocytic nevi, epidermal nevi, acquired tumors (pilomatricomas), and other lesions, along with steady epidemiologic, translational, and clinical work, evolves our knowledge and potential therapies.

 

 

Inflammatory skin disorders: Acne, psoriasis, and atopic dermatitis

The care of pediatric inflammatory skin disorders has evolved, but more slowly for some diseases than others. Acne vulgaris is now recognized as much more common under age 12 than previously, presumably reflecting earlier pubertal changes in our preteens. Over the past 30 years, therapy has evolved with the use of topical retinoids (still underused by pediatricians, considered a “practice gap”), hormonal therapy with combined oral contraceptives, and oral isotretinoin, a powerful but highly effective systemic agent for severe and refractory acne. Specific pediatric guidelines came much later, with expert recommendations formulated by the American Acne and Rosacea Society and endorsed by the American Academy of Pediatrics in 2013. Over the past few years, there has been a push by experts for more judicious use of antibiotics for acne (oral and topical) to minimize the emergence of bacterial resistance. There are unanswered questions as we evolve our care: How will the new topical antiandrogens be used? Will spironolactone become part of hormonal therapy under age 18? Will the insights on certain strains of Cutibacterium acnes being associated with worse acne translate to microbiome or vaccine-based strategies?

Pediatric psoriasis has suffered, being “behind in the revolution” of biologic agents because of delayed approval of any biologic agent for treatment of pediatric psoriasis in the United States until just a few years ago, and lags behind Europe and elsewhere in the world by almost a decade. Only this year have we expanded beyond one biologic agent approved for under age 12 and two for ages 12 and older, with other approvals expected including interleukin (IL)-17 and IL-23 agents. Adult psoriasis has been recognized to be associated with a broad set of comorbidities, including obesity and early heart disease, and there is now research on how children are at risk as well, with new recommendations on how to screen children with psoriasis, supplied first by PeDRA and then in the new American Academy of Dermatology-National Psoriasis Foundation pediatric psoriasis guidelines .



Pediatric atopic dermatitis (AD) is in its early years of revolution. In the 50-year period of our thought experiment, AD has increased in prevalence from 5% or less of the pediatric population to 10%-15%. Treatment of most individuals has remained the same over the decades: Good skin care, frequent moisturizers, topical corticosteroids for flares, and management of infection if noted. The topical calcineurin inhibitors (TCIs) broadened the therapeutic approach when introduced in 2000 and 2001, but the boxed warning resulted in some practitioners minimizing their use of these useful agents. But newer studies are markedly reassuring about their safe use in children.

Steroid phobia, as well as concerns about potential side effects of the TCIs, has resulted in undertreatment of childhood AD. It is quite common to see multiple children during pediatric dermatology office hours with poorly controlled eczema, high body-surface areas of eczema, compromised sleep, secondary infections, and anxiety and depression, especially in our moderate to severe adolescents. The field is “hot” with new topical and systemic agents, including our few years’ experience with topical crisaborole, a phosphodiesterase (PDE)-4 inhibitor; and dupilumab, an IL-4-alpha blocker – the first biologic agent approved for AD and the first systemic agent (other than oral corticosteroids), just extended from 12 years to 6 years of age! As dupilumab gets studied for younger children, other biologics (including IL-13 and IL-31 blockers) are undertaking pediatric and/or adolescent trials, oral and topical JAK inhibitors are including adolescents in core clinical trials, and other novel topical agents are under study, including an aryl-hydrocarbon receptor–modulating agent and other PDE-4 inhibitors.

 

 

Procedural pediatric dermatology: From liquid nitrogen to laser, surgery, and multimodal skin care

The first generation of pediatric dermatologists were considered medical dermatologist specialists. The care of the conditions discussed above, as well as genodermatoses, diagnostic dilemmas, and management of dermatologic manifestations of systemic disease and other conditions, was the “bread and butter” of pediatric dermatology care. When I was in training, my mentor Paul Honig, MD, at the Children’s Hospital of Philadelphia had a procedure half-day each week, where he would care for a few patients who needed liquid nitrogen therapy for warts, or who needed biopsies. It was uncommon to have a large procedural/surgical part of pediatric dermatology practice. But this is now a routine part of many specialists in the field. How did this change occur?

Dr. Lawrence F. Eichenfield

The fundamental shift began to occur with the introduction of the pulsed dye laser for treatment of port-wine birthmarks in children with minimal scarring, and a seminal article published in the New England Journal of Medicine in 1989. Vascular lesions including port-wine stains were common, and pediatric dermatologists managed these patients for both diagnosis and medical management. Also, dermatology residencies at this time offered training in cutaneous surgery, excisions (including Mohs surgery) and repairs, and trainees in pediatric dermatology were “trained up” to high levels of expertise. As lasers were incorporated into dermatology residency work and practices, pediatric dermatologists developed the exposure and skill to do this work. An added advantage was having the knowledge of how to handle children and adolescents in an age-appropriate manner, with consideration of methods to minimize the pain and anxiety of procedures. Within a few years, pediatric dermatologists were at the forefront of the use of topical anesthetics (EMLA and liposomal lidocaine) and had general anesthesia privileges for laser and excisional surgery.

So while pediatric dermatologists still do “small procedures” every hour in most practices (cryotherapy for warts, cantharidin for molluscum, shave and punch biopsies), a subset now have extensive procedural practices, which in recent years has extended to pigment lesion lasers (to treat nevus of Ota, for example), hair laser, and combinations of lasers, including fractionated CO2 technology, to treat hypertrophic, constrictive and/or deforming scars.

First SGLT1/2 inhibitor shows ‘spectacular’ phase 3 safety and efficacy in T2D

Article Type
Changed
Tue, 05/03/2022 - 15:07

Sotagliflozin, a novel type of sodium-glucose cotransporter inhibitor, showed the diverse benefits this drug class provides along some new twists in a pair of international pivotal trials that together enrolled nearly 12,000 patients with type 2 diabetes.

Dr. Deepak Bhatt

Unprecedented benefits were seen for the first time with a drug, sotagliflozin (Zynquista) that produces both sodium-glucose cotransporter 2 inhibition as well as SGLT1 inhibition.

They included a big reduction in both MIs and strokes; an ability to meaningfully reduce hyperglycemia in patients with severe renal dysfunction with an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73 m2; an ability to safely and effectively start in patients still hospitalized (but stable) for an acute heart failure episode; and a striking 37% relative risk reduction in cardiovascular death, heart failure hospitalizations, or an urgent outpatient visit for heart failure in 739 of the patients enrolled in both trials who had heart failure with preserved ejection fraction (HFpEF).

These studies produced for the first time evidence from controlled, prospective, randomized trials that a drug could improve the outcome of HFpEF patients.

All these novel outcomes came on top of the usual benefits clinicians have generally seen across the SGLT2 inhibitors already on the U.S. market: reductions in cardiovascular death and heart failure hospitalizations among all patients with type 2 diabetes, preservation of renal function, and hemoglobin A1c lowering among T2D patients with eGFR levels of at least 30 mL/min per 1.73 m2.

“The data look spectacular,” summed up Deepak L. Bhatt, MD, who presented the results from the two trials, SOLOIST-WHF and SCORED, in talks at the virtual scientific sessions of the American Heart Association.

“I think sotagliflozin has the potential to be the best in class” based on the several added attributes shown in the two trials, he said in an interview. “We’ve shown that it is very safe, well tolerated, and effective.”

The primary results were a significant 33% relative risk reduction with sotagliflozin treatment, compared with placebo in the rate of total cardiovascular deaths, hospitalizations for heart failure, or urgent outpatient visits for heart failure during just over 9 months of median follow-up among patients with T2D recently hospitalized for heart failure in SOLOIST-WFH. And a significant 26% relative risk reduction with sotagliflozin for the same endpoint after a median follow-up of just over 14 months in SCORED, which enrolled patients with T2D and chronic kidney disease.

“Sotagliflozin adds to the SGLT2 inhibitor story,” and the SOLOIST-WHF results “may shift our focus to vulnerable, acute heart failure patients with an opportunity to treat during the transition phase,” when these patients leave the hospital, commented Jane E. Wilcox, MD, the study’s designated discussant and a heart failure cardiologist at Northwestern Medicine in Chicago.
 

A dual SGLT inhibitor

What sets sotagliflozin apart from the SGLT2 inhibitors is that it not only inhibits that protein but also SGTL1, which primarily resides in the gastrointestinal tract and is the main route for gut absorption of glucose. Dr. Bhatt said that he was unaware of any other SGLT1/2 inhibitors currently in advanced clinical testing.

The activity of sotagliflozin against the SGLT1 protein likely explains its ability to cut A1c levels in patients with severe renal dysfunction, a condition that stymies glucose lowering by SGLT2 inhibitors. In SCORED, which randomized 10,584 patients with T2D at 750 study sites in 44 countries, 813 patients (8%) had an eGFR of 25-29 mL/min per 1.73 m2 at enrollment. Sotagliflozin treatment led to an average 0.6% cut in A1c in this subgroup, and by the same average amount among the patients with GFRs of 30-60 mL/min per 1.73 m2.

“This is a huge finding for endocrinologists and primary care physicians” who treat patients with T2D who have severe renal dysfunction, said Dr. Bhatt, a professor of medicine at Harvard Medical School in Boston. “It’s a good enough reason by itself to approve this drug.”

The same mechanism may also be behind another unexpected finding in SCORED. Treatment with sotagliflozin cut the rate of total episodes of cardiovascular death, nonfatal MI, or nonfatal stroke by an absolute 1.6%, compared with placebo, and by a relative 23%. This benefit was largely driven by a 32% relative risk reduction total in MIs, and a 34% relative risk reduction in total stroke, both significant differences.

“No SGLT2 inhibitor has shown a reduction in stroke, and the MI signals have been mixed. The sizable MI and stroke effects are unique to sotagliflozin,” compared with the SGLT2 inhibitors, and likely reflect one or more mechanisms that result from blocked gut SGLT1 and a cut in GI glucose uptake, said Dr. Bhatt. “Probably some novel mechanism we don’t fully understand.”
 

First-ever HFpEF benefit

In contrast to these two benefits that are probably unique to drugs that inhibit the SGLT1 protein, sotagliflozin showed two other notable and unprecedented benefits that are likely generalizable to the SGLT2 inhibitors.

First is the striking benefit for HFpEF. Neither SOLOIST, which enrolled 1,222 patients with T2D and just hospitalized for worsening heart failure, nor SCORED, which enrolled patients with T2D and chronic kidney disease based exclusively on an eGFR of 25-60 mL/min per 1.73 m2, excluded patients with HFpEF, defined as heart failure patients with a left ventricular ejection fraction of at least 50%. The two studies together included a total of 739 of these patients, and they split fairly evenly between treatment with sotagliflozin or placebo.

The combined analysis showed that the incidence rate for the primary endpoint in both SOLOIST and SCORED was 59% with placebo and 39% with sotagliflozin, an absolute event reduction of 11.6 events/100 patient-years, and a significant 37% relative risk reduction, with a number needed to treat to prevent 1 event per year event of 9.

Although this observation comes from a nonprespecified combined analysis, “to me this result seems real, and I think it’s a class effect that I’m willing to extrapolate to the SGLT2 inhibitors,” Dr. Bhatt said. “It will change my practice,” he added, by spurring him to more aggressively prescribe an SGLT2 inhibitor to a patient with T2D and HFpEF.

“I think there has been some hesitation to use SGLT2 inhibitors in T2D patients with HFpEF” because of the paucity of data in this population, even though labeling and society recommendations do not rule it out. “I hope this finding will move that needle, and also generally improve SGLT2 inhibitor uptake, which has been low,” he said.
 

 

 

Also safe soon after acute heart failure decompensation

The other finding likely generalizable to SGLT2 inhibitors stems from the design of SOLOIST-WHF, which tested the efficacy and safety of starting sotagliflozin in patients with T2D as soon as they were stable after hospitalization for acute heart failure decompensation.

“Showing safety and efficacy when started in the hospital is pretty meaningful, because its tells patients that this drug is important and they should stay on it,” which should improve adherence, predicted Dr. Bhatt, who is also executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital in Boston. “That’s the ultimate treatment path to prevent patients from falling through the cracks” and failing to receive an SGLT2 inhibitor.



SOLOIST-WHF enrolled patients hospitalized for worsening heart failure who also required intravenous diuretic treatment but had become stable enough to transition to an oral diuretic and come off oxygen. During a median follow-up of just over 9 months (both SOLOIST-WHF and SCORED ended sooner than planned because of a change in drug company sponsorship), treatment with sotagliflozin cut the primary endpoint by a relative 33%, compared with placebo, and with an absolute reduction of 25 events per 100 patient-years for a number needed to treat of 4. Sotagliflozin produced a strikingly high level of treatment efficiency driven by the high event rate in these recently decompensated patients. The benefit also appeared quickly, with a significant cut in events discernible within 28 days.

Extrapolating this finding to the SGLT2 inhibitors is “not a huge leap of faith,” Dr. Bhatt said.

“There is a role for sotagliflozin in acute heart failure. It showed benefit in these high-risk, transition-phase patients,” said Dr. Wilcox.

Simultaneously with Dr. Bhatt’s presentation, results of SOLOIST-WHF and SCORED were published online in the New England Journal of Medicine.

The trials were sponsored initially by Sanofi, and more recently by Lexicon. Dr. Bhatt has received research funding from both companies, and also from several other companies. He also is an adviser to several companies. Dr. Wilcox has been a consultant to Boehringer Ingelheim and Medtronic.

Sotagliflozin, a novel type of sodium-glucose cotransporter inhibitor, showed the diverse benefits this drug class provides along some new twists in a pair of international pivotal trials that together enrolled nearly 12,000 patients with type 2 diabetes.

Dr. Deepak Bhatt

Unprecedented benefits were seen for the first time with a drug, sotagliflozin (Zynquista) that produces both sodium-glucose cotransporter 2 inhibition as well as SGLT1 inhibition.

They included a big reduction in both MIs and strokes; an ability to meaningfully reduce hyperglycemia in patients with severe renal dysfunction with an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73 m2; an ability to safely and effectively start in patients still hospitalized (but stable) for an acute heart failure episode; and a striking 37% relative risk reduction in cardiovascular death, heart failure hospitalizations, or an urgent outpatient visit for heart failure in 739 of the patients enrolled in both trials who had heart failure with preserved ejection fraction (HFpEF).

These studies produced for the first time evidence from controlled, prospective, randomized trials that a drug could improve the outcome of HFpEF patients.

All these novel outcomes came on top of the usual benefits clinicians have generally seen across the SGLT2 inhibitors already on the U.S. market: reductions in cardiovascular death and heart failure hospitalizations among all patients with type 2 diabetes, preservation of renal function, and hemoglobin A1c lowering among T2D patients with eGFR levels of at least 30 mL/min per 1.73 m2.

“The data look spectacular,” summed up Deepak L. Bhatt, MD, who presented the results from the two trials, SOLOIST-WHF and SCORED, in talks at the virtual scientific sessions of the American Heart Association.

“I think sotagliflozin has the potential to be the best in class” based on the several added attributes shown in the two trials, he said in an interview. “We’ve shown that it is very safe, well tolerated, and effective.”

Factor XI inhibitor–based anticoagulation strategies gain ground

Article Type
Changed
Wed, 11/18/2020 - 12:37

Factor XI has emerged as a promising target for new anticoagulants, and several strategies for inhibiting the enzyme to reduce stroke, thromboembolism, and bleeding risk are under investigation, according to Jeffrey I. Weitz, MD.

These strategies could pick up where direct-acting oral anticoagulants leave off, he suggested during a presentation at the biennial summit of the Thrombosis & Hemostasis Societies of North America.

“We all know that the direct oral anticoagulants – the DOACs – are an advance over vitamin K antagonists,” said Dr. Weitz, professor of medicine and biochemistry at McMaster University, Hamilton, Ontario.

Not only are DOACs at least as effective as vitamin K antagonists such as warfarin for stroke prevention in atrial fibrillation or for treatment of venous thromboembolism (VTE), but they also reduce intracranial bleeding and major bleeding risk in those settings, respectively, and they are more convenient to administer because they can be delivered using fixed doses without the need for coagulation monitoring, he added.

Still, new targets are needed, he said, explaining that, although DOACs moved closer to the goal of attenuating thrombosis without increasing the risk of bleeding, annual rates of major bleeding remain at 2%-3% in the atrial fibrillation population, and rates of major and clinically relevant nonmajor bleeding are about 10%.

“The fear of bleeding leads to underuse of anticoagulants for eligible patients with atrial fibrillation and inappropriate use of low-dose [non–vitamin K antagonist oral anticoagulant] regimens, which can leave patients unprotected from thrombotic complications,” he said.
 

Factor XI

That’s where Factor XI (FXI) may come in, Dr. Weitz said.

Current anticoagulants target enzymes, including FXa or thrombin, in the common pathway of coagulation, but the intrinsic pathway at the level of FXI and FXII has attracted attention in recent years.

The intrinsic pathway is activated when blood comes into contact with medical devices like stents, mechanical heart valves, or central venous catheters, but evidence also suggests that it plays a role in clot stabilization and growth, he explained, noting additional evidence of attenuation of thrombosis in mice deficient in FXI or FXII and in animals with FXI or FXII inhibitors.

“There is no bleeding with congenital FXII deficiency, and patients with FXI deficiency rarely have spontaneous bleeding, although they can bleed with surgery or trauma,” he noted. “Therefore, the promise of contact pathway inhibition is that we can attenuate thrombosis with little or no disruption of hemostasis.”

The initiators of the intrinsic pathway are naturally occurring polyphosphates that can activate FXI and FXII, promote platelet activation, and lead to thrombosis. A number of agents are being investigated to target these enzymes – particularly FXI, for which the strongest epidemiological and other evidence of its link with thrombosis exists. He noted that FXI deficiency appears protective against deep-vein thrombosis (DVT) and ischemic stroke, whereas high levels are linked with an increased risk of venous and arterial thrombosis.



Investigative strategies include the use of antisense oligonucleotides to reduce hepatic synthesis of FXI, aptamers to bind FXI and block its activity, antibodies to bind FXI and block its activation or activity, and small molecules to bind reversibly to the active site of FXI and block its activity “much like the DOACs block the activity of FXa or thrombin.”

“We have to remember that the DOACs have taken over from vitamin K antagonists, like warfarin, for many indications, and as they go generic their uptake will increase even further,” Dr. Weitz said. “When we compare the FXI inhibitors with existing anticoagulants, we don’t necessarily want to go up against the DOACs – we’re looking for indications where [DOACs] have yet to be tested or may be unsafe.”

Potential indications include the following:

Prevention of major adverse cardiovascular events in patients with end-stage renal disease with or without atrial fibrillation.

Provision of a safer platform for antiplatelet therapy in patients with acute coronary syndrome.

Secondary stroke prevention.

Prevention or treatment of cancer-associated VTE.

Prevention of thrombosis associated with central venous catheters, left ventricular assist devices, or mechanical heart valves.

Agents in development

Of the FXI inhibitors in development, ISIS-FXIRx, an antisense oligonucleotide against FXI, is furthest along. In a study published in Blood, ISIS-FXIRx produced a dose-dependent and sustained reduction in FXI levels in healthy volunteers, and in a later randomized study published in The New England Journal of Medicine, it significantly reduced the incidence of DVT in patients undergoing voluntary total knee arthroplasty (30.4% with enoxaparin vs. 4.2% with ISIS-FXIRx at a dose of 300 mg). Bleeding rates were 8.3% and 2.6%, respectively.

The findings showed the potential for reducing thrombosis without increasing bleeding by targeting FXI, Dr. Weitz said, adding that ISIS-FXIRx was also evaluated in a small study of patients with end-stage renal disease undergoing hemodialysis and was shown to produce a dose-dependent reduction in FXI levels and to reduce the incidence of category 3 and 4 clotting in the air trap and dialyzer, compared with placebo, when given in addition to heparin.

This suggests that FXI knockdown can attenuate device-associated clotting to a greater extent than heparin alone, Dr. Weitz said.

The FXIa-directed inhibitory antibody osocimab has also been evaluated in both healthy volunteers and in patients undergoing total knee arthroplasty. In a 2019 study of healthy volunteers, a single IV injection showed a dose-dependent pharmacokinetic profile and produced FXI inhibition for about 1 month, and in the FOXTROT trial published in January in JAMA by Dr. Weitz and colleagues, osocimab was shown to reduce the incidence of symptomatic VTE, asymptomatic DVT, and VTE-related death up to day 10-13 after total knee arthroplasty.

Osocimab at doses ranging from 0.3-1.8 mg/kg given postoperatively or preoperatively were noninferior to enoxaparin (rates of 15.7%-23.7% vs. 26.3%), and osocimab at a preoperative dose of 1.8 mg/kg was superior to both enoxaparin and apixaban (11.5% vs. 26.3% and 14.5%, respectively), he said.

Bleeding rates ranged from 0%-5% with osocimab, compared with 6% with enoxaparin and 2% with apixaban
 

Ongoing studies

Currently ongoing studies of FXI-directed anticoagulation strategies include a study comparing ISIS-FXIRx with placebo in 200 patients with end-stage renal disease, a study comparing osocimab with placebo in 600 patients with end-stage renal disease, and a study comparing abelacimab – an antibody that binds to FXI and prevents its activation by either FXIIa or thrombin, with enoxaparin in 700 patients undergoing total knee arthroplasty, Dr. Weitz said.

Additionally, there is “considerable activity” with small molecule inhibitors of FXIa, including a phase 2, placebo-controlled, dose-ranging study looking at the novel JNG-7003/BMS-986177 agent for secondary stroke/transient ischemic attack prevention in 2,500 patients and a phase 2 study comparing it with enoxaparin for postoperative thromboprophylaxis in 1,200 patients undergoing total knee arthroplasty.

Parallel phase 2 studies are also underway to compare the novel BAY-2433334 small molecule inhibitor with placebo for stroke/transient ischemic attack prevention, with apixaban for atrial fibrillation, and for prevention of major adverse cardiovascular events in patients with acute MI.

These ongoing trials will help determine the risk-benefit profile of FXI inhibitors he said.

Session comoderator Anne Rose, PharmD, pharmacy coordinator at the University of Wisconsin, Madison, noted that these types of agents have been discussed “for quite some time” and asked whether they will be available for use in clinical practice in the near future.

Dr. Weitz predicted it will be at least a few years. The studies are just now moving to phase 2b and will still need to be evaluated in phase 3 trials and for appropriate new indications, he said.

Dr. Weitz reported research support from Canadian Institutes of Health research, Heart and Stroke Foundation, and Canadian Fund for Innovation, and he is a consultant and/or scientific advisory board member for Anthos, Bayer, Boehringer-Ingelheim, Bristol-Myers Squibb, Daiichi-Sankyo, Ionis Pharmaceuticals, Janssen, Merck, Novartis, Pfizer, Portola, Servier , and Thetherex.

These strategies could pick up where direct-acting oral anticoagulants leave off, he suggested during a presentation at the biennial summit of the Thrombosis & Hemostasis Societies of North America.

“We all know that the direct oral anticoagulants – the DOACs – are an advance over vitamin K antagonists,” said Dr. Weitz, professor of medicine and biochemistry at McMaster University, Hamilton, Ontario.

Not only are DOACs at least as effective as vitamin K antagonists such as warfarin for stroke prevention in atrial fibrillation or for treatment of venous thromboembolism (VTE), but they also reduce intracranial bleeding and major bleeding risk in those settings, respectively, and they are more convenient to administer because they can be delivered using fixed doses without the need for coagulation monitoring, he added.

Still, new targets are needed, he said, explaining that, although DOACs moved closer to the goal of attenuating thrombosis without increasing the risk of bleeding, annual rates of major bleeding remain at 2%-3% in the atrial fibrillation population, and rates of major and clinically relevant nonmajor bleeding are about 10%.

“The fear of bleeding leads to underuse of anticoagulants for eligible patients with atrial fibrillation and inappropriate use of low-dose [non–vitamin K antagonist oral anticoagulant] regimens, which can leave patients unprotected from thrombotic complications,” he said.
 

Factor XI

That’s where Factor XI (FXI) may come in, Dr. Weitz said.

Current anticoagulants target enzymes, including FXa or thrombin, in the common pathway of coagulation, but the intrinsic pathway at the level of FXI and FXII has attracted attention in recent years.

The intrinsic pathway is activated when blood comes into contact with medical devices like stents, mechanical heart valves, or central venous catheters, but evidence also suggests that it plays a role in clot stabilization and growth, he explained, noting additional evidence of attenuation of thrombosis in mice deficient in FXI or FXII and in animals with FXI or FXII inhibitors.

“There is no bleeding with congenital FXII deficiency, and patients with FXI deficiency rarely have spontaneous bleeding, although they can bleed with surgery or trauma,” he noted. “Therefore, the promise of contact pathway inhibition is that we can attenuate thrombosis with little or no disruption of hemostasis.”

The initiators of the intrinsic pathway are naturally occurring polyphosphates that can activate FXI and FXII, promote platelet activation, and lead to thrombosis. A number of agents are being investigated to target these enzymes – particularly FXI, for which the strongest epidemiological and other evidence of its link with thrombosis exists. He noted that FXI deficiency appears protective against deep-vein thrombosis (DVT) and ischemic stroke, whereas high levels are linked with an increased risk of venous and arterial thrombosis.



Investigative strategies include the use of antisense oligonucleotides to reduce hepatic synthesis of FXI, aptamers to bind FXI and block its activity, antibodies to bind FXI and block its activation or activity, and small molecules to bind reversibly to the active site of FXI and block its activity “much like the DOACs block the activity of FXa or thrombin.”

“We have to remember that the DOACs have taken over from vitamin K antagonists, like warfarin, for many indications, and as they go generic their uptake will increase even further,” Dr. Weitz said. “When we compare the FXI inhibitors with existing anticoagulants, we don’t necessarily want to go up against the DOACs – we’re looking for indications where [DOACs] have yet to be tested or may be unsafe.”

Potential indications include the following:

Prevention of major adverse cardiovascular events in patients with end-stage renal disease with or without atrial fibrillation.

Provision of a safer platform for antiplatelet therapy in patients with acute coronary syndrome.

Secondary stroke prevention.

Prevention or treatment of cancer-associated VTE.

Prevention of thrombosis associated with central venous catheters, left ventricular assist devices, or mechanical heart valves.

Agents in development

Of the FXI inhibitors in development, ISIS-FXIRx, an antisense oligonucleotide against FXI, is furthest along. In a study published in Blood, ISIS-FXIRx produced a dose-dependent and sustained reduction in FXI levels in healthy volunteers, and in a later randomized study published in The New England Journal of Medicine, it significantly reduced the incidence of DVT in patients undergoing voluntary total knee arthroplasty (30.4% with enoxaparin vs. 4.2% with ISIS-FXIRx at a dose of 300 mg). Bleeding rates were 8.3% and 2.6%, respectively.

The findings showed the potential for reducing thrombosis without increasing bleeding by targeting FXI, Dr. Weitz said, adding that ISIS-FXIRx was also evaluated in a small study of patients with end-stage renal disease undergoing hemodialysis and was shown to produce a dose-dependent reduction in FXI levels and to reduce the incidence of category 3 and 4 clotting in the air trap and dialyzer, compared with placebo, when given in addition to heparin.

This suggests that FXI knockdown can attenuate device-associated clotting to a greater extent than heparin alone, Dr. Weitz said.

The FXIa-directed inhibitory antibody osocimab has also been evaluated in both healthy volunteers and in patients undergoing total knee arthroplasty. In a 2019 study of healthy volunteers, a single IV injection showed a dose-dependent pharmacokinetic profile and produced FXI inhibition for about 1 month, and in the FOXTROT trial published in January in JAMA by Dr. Weitz and colleagues, osocimab was shown to reduce the incidence of symptomatic VTE, asymptomatic DVT, and VTE-related death up to day 10-13 after total knee arthroplasty.

Osocimab at doses ranging from 0.3-1.8 mg/kg given postoperatively or preoperatively were noninferior to enoxaparin (rates of 15.7%-23.7% vs. 26.3%), and osocimab at a preoperative dose of 1.8 mg/kg was superior to both enoxaparin and apixaban (11.5% vs. 26.3% and 14.5%, respectively), he said.

Bleeding rates ranged from 0%-5% with osocimab, compared with 6% with enoxaparin and 2% with apixaban
 

Ongoing studies

Currently ongoing studies of FXI-directed anticoagulation strategies include a study comparing ISIS-FXIRx with placebo in 200 patients with end-stage renal disease, a study comparing osocimab with placebo in 600 patients with end-stage renal disease, and a study comparing abelacimab – an antibody that binds to FXI and prevents its activation by either FXIIa or thrombin, with enoxaparin in 700 patients undergoing total knee arthroplasty, Dr. Weitz said.

Additionally, there is “considerable activity” with small molecule inhibitors of FXIa, including a phase 2, placebo-controlled, dose-ranging study looking at the novel JNG-7003/BMS-986177 agent for secondary stroke/transient ischemic attack prevention in 2,500 patients and a phase 2 study comparing it with enoxaparin for postoperative thromboprophylaxis in 1,200 patients undergoing total knee arthroplasty.

Parallel phase 2 studies are also underway to compare the novel BAY-2433334 small molecule inhibitor with placebo for stroke/transient ischemic attack prevention, with apixaban for atrial fibrillation, and for prevention of major adverse cardiovascular events in patients with acute MI.

These ongoing trials will help determine the risk-benefit profile of FXI inhibitors he said.

Session comoderator Anne Rose, PharmD, pharmacy coordinator at the University of Wisconsin, Madison, noted that these types of agents have been discussed “for quite some time” and asked whether they will be available for use in clinical practice in the near future.

Dr. Weitz predicted it will be at least a few years. The studies are just now moving to phase 2b and will still need to be evaluated in phase 3 trials and for appropriate new indications, he said.

Dr. Weitz reported research support from Canadian Institutes of Health research, Heart and Stroke Foundation, and Canadian Fund for Innovation, and he is a consultant and/or scientific advisory board member for Anthos, Bayer, Boehringer-Ingelheim, Bristol-Myers Squibb, Daiichi-Sankyo, Ionis Pharmaceuticals, Janssen, Merck, Novartis, Pfizer, Portola, Servier , and Thetherex.

Pediatric News welcomes Herschel Lessin, MD, to the editorial advisory board.

Dr. Herschel Lessin

Dr. Lessin has been a practicing pediatric clinician for the past 39 years at The Children’s Medical Group. In 1997, he was a founding partner of one of the first private practice “supergroups” by merging two competing pediatric practices into one and expanding it to 25 clinicians, with eight offices in three counties in New York state’s Mid-Hudson Valley. The group provides pediatric care to more than 30,000 children and has a nearly 90-year history, across its various incarnations, providing such care.

Dr. Lessin received his medical degree from Stanford (Calif.) University and trained in pediatrics at Yale-New Haven (Conn.) Medical Center. He has been active in national policy and leadership in the American Academy of Pediatrics, having served on the executive committee of the Section of Administration and Practice Management, the national Committee on Practice and Ambulatory Medicine, and his current appointment to the national Private Payer Advocacy Advisory Committee. In those roles he has authored several national policy statements and clinical guidelines, including “Increasing Immunization Coverage,” “Immunizing Parents and Other Close Family Contacts in the Pediatric Office Setting,” “Instrument-Based Pediatric Vision Screening Policy Statement,” and most recently, “Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents.” He is also the coeditor of the AAP’s ADHD toolkit for clinicians published in 2019. Dr. Lessin served as the director of clinical research for his group for 5 years and the medical director for the practice for 10 years.

He has served as a faculty member at numerous local and regional pediatric meetings. He has been a faculty member at the AAP’s annual national conference and exposition for the past decade, speaking on a variety of topics. Dr. Lessin also has been an invited speaker internationally at pediatric conferences in India and Egypt. He has participated in more than a dozen medical missions to developing countries in Latin America, the Caribbean, Africa, and Vietnam. His expertise includes practice management, the business of medicine, immunizations, ADHD, and liability topics. He has been a testifying expert witness for both defense and plaintiff in medical malpractice litigation for more than 30 years. He founded and served as president of a medical independent practice association that began with 12 physicians and grew to over 3,000 doctors. He is also a certified managed care executive. His most recent interest has been becoming a professional voice-over actor!

While performing all of the above, Dr. Lessin is a dedicated community pediatrician whose first love and primary goal has remained providing the highest quality medical care to children while helping his colleagues manage their businesses in order to be able to survive and continue to provide such care.
