HDL anti-inflammatory effects show prognostic potential
The high-density lipoprotein particle’s complexity as a mediator of cardiovascular risk was on display in a case-control study that, the researchers say, points to its anti-inflammatory capacity as potentially a worthy addition to standard CV risk assessments.
A measure of HDL anti-inflammatory capacity in a prospective community cohort was inversely related to future CV risk independent of HDL’s role in cholesterol transport, total cholesterol, and other established biomarkers, as well as any lipid-modifying therapy.
The current analysis “identified an impaired HDL anti-inflammatory capacity as a functional metric prospectively associated with increased cardiovascular risk in the general population,” observed the authors of the study, published April 12, 2021, in Circulation, led by Congzhuo Jia, MD, University of Groningen (the Netherlands).
“In contrast with the cholesterol efflux function of HDL that tracks moderately with HDL cholesterol levels,” they wrote, HDL anti-inflammatory capacity was not significantly correlated with actual levels of the lipoprotein or a major constituent, apolipoprotein A1 (apoA1). Nor was it correlated with levels of a more generalized inflammatory biomarker, C-reactive protein by high-sensitivity assay (hsCRP).
In a test of its independence as a prognosticator, HDL anti-inflammatory capacity significantly and meaningfully improved prediction of CV events in the study after it was added to the familiar Framingham risk equations.
Measurement of HDL anti-inflammatory properties, therefore, has the potential to improve current CV risk assessments in people without clinical heart disease, the authors proposed.
The study “adds to our understanding of the potential cardioprotective role of HDL,” Michael Miller, MD, University of Maryland, Baltimore, said in an interview.
“We’ve known for some time that HDL has anti-inflammatory properties in vitro, and my understanding is this is the first study to assess these anti-inflammatory properties in a clinical trial,” said Dr. Miller, who studies lipid metabolism and directs the Center for Preventive Cardiology at his center but isn’t an author of the report.
The study is part of a long line of research aiming to “untangle the complexities of HDL and try to get a better handle as to the properties that make it cardioprotective,” he said. For example, “high levels are not always associated with cardioprotection, and low levels don’t always imply increased risk.”
The current findings highlight a quality of HDL that might be prognostic but also independent of its concentrations, apoA1 content, or cholesterol efflux capacity, Dr. Miller noted. That makes HDL anti-inflammatory capacity a “promising feature” of HDL that, if confirmed in further studies, could potentially be brought into the mainstream for CV risk prediction. “But it’s too premature at this time.”
The study of participants in the population-based PREVEND cohort study compared 340 patients with a first CV event – CV death, ischemic heart disease, nonfatal MI, or coronary revascularization – over a median of about 10 years with the same number of participants without such events. The two cohorts of people from the same city in the Netherlands had been matched according to sex, smoking status, age, and HDL cholesterol levels at baseline.
No measured clinical or laboratory value, the group wrote, was significantly correlated with HDL anti-inflammatory capacity, defined here as ability to suppress vascular cell adhesion molecule-1 (VCAM-1) mRNA expression as induced by tumor necrosis factor–alpha in endothelial cells in vitro.
HDL anti-inflammatory capacity was significantly lower in the case cohort, compared with the control cohort (P < .001), and was inversely related to new CV events, at an odds ratio per 1 standard deviation of 0.74 (95% confidence interval, 0.61-0.90; P = .002). Covariate adjustments included body mass index; alcohol intake; diabetes and hypertension status; use of lipid-lowering medicine; levels of total cholesterol, apoA1, triglyceride, and hsCRP; and measures of renal function.
No significant association was seen between HDL anti-inflammatory capacity and cholesterol efflux capacity (coefficient of correlation, −0.02; P > .05). But both metrics were independently associated with CV disease events. The OR per 1 standard deviation was 0.74 (95% CI, 0.61-0.90; P = .002) for cholesterol efflux capacity and 0.66 (95% CI, 0.54-0.81; P < .001) for HDL anti-inflammatory capacity.
Adding HDL anti-inflammatory capacity to the Framingham risk score significantly improved its predictive power; its likelihood-ratio statistic rose from 10.50 to 20.40 (P = .002), the group wrote. The addition of cholesterol efflux capacity further elevated the risk score’s likelihood-ratio statistic to 32.84 (P = .0005).
The analysis has all the limitations of a case-control study, Dr. Miller said, but it does “show a potential reasonable association” between anti-inflammatory capacity and CV risk “that needs to be taken to the next level.”
For example, it could be explored in a controlled trial that tracks anti-inflammatory capacity in individuals who receive an intervention that is likely to improve the biomarker – such as weight loss, he proposed – and follows them for clinical outcomes.
“If you want to elevate the stature of the anti-inflammatory index,” Dr. Miller said, “you will need to show that it’s clinically meaningful.”
Dr. Jia reported no conflicts. Dr. Miller has no relevant disclosures.

Renal, cardiovascular damage may develop in mild SLE despite treatment
Patients with mild to moderate systemic lupus erythematosus (SLE) disease activity without any past history of organ damage may still progress to develop damage, particularly renal and cardiovascular disease, or death, in a relatively short amount of follow-up time, new research suggests.
The study, published in Lupus Science & Medicine, also showed that use of hydroxychloroquine lowered the risk of death and renal damage, whereas use of NSAIDs or any antihypertensives increased risk for cardiovascular damage.
“The impact of irreversible organ system damage in the prognosis of SLE remains a major concern because patients who develop damage are more likely to accrue additional damage and die,” wrote Deanna Hill, PhD, of GlaxoSmithKline, Collegeville, Pa., and coauthors, including Michelle Petri, MD, of Johns Hopkins University, Baltimore.
The researchers followed 1,168 adult patients with SLE from the Johns Hopkins Lupus Cohort, most of whom were women, 55% of whom were White and 39% of whom were Black. They divided the follow-up period into three parts: first year after enrollment into the cohort as background, second year as observation period, and the remainder of follow-up time until damage occurred, death, or end of available data.
At baseline, 55% of patients had mild to moderate disease, defined as an adjusted mean SELENA-SLEDAI (Safety of Estrogens in Lupus Erythematosus National Assessment SLE Disease Activity Index) score of less than 3. Patients had a median adjusted mean SELENA-SLEDAI score of 3 in the first year, which dropped to 2 in the observation period and remained there during the rest of follow-up.
Eight percent of patients died during the follow-up period. Each one-unit mean increase in SELENA-SLEDAI score during the 1-year observation period was associated with a significant 22% increase in the subsequent risk of death during the subsequent follow-up period (95% confidence interval, 1.13-1.32; P < .001).
Three-quarters of patients (n = 888) had no history of damage at the start of the follow-up period, but 39% of these patients had developed damage by the end of follow-up. Among patients without prior damage, a single-unit increase in disease activity score was also associated with a 9% increase in the risk of accruing organ damage (95% CI, 1.04-1.15; P < .001) after adjustment for confounding factors.
While only 3% of patients – most of whom were women – developed renal damage during the follow-up period, a one-unit increase in disease activity score was associated with a 24% increase in the risk of renal damage (95% CI, 1.08-1.42, P = .003).
The researchers found that 7% of patients developed cardiovascular damage during the follow-up period, and each one-unit increase in disease activity score was associated with a 17% increase in the risk of cardiovascular damage (95% CI, 1.07-1.29; P < .001).
“The findings in this analysis corroborate the influence of disease activity for renal and cardiovascular damage accrual and death and also extend the findings to patients with SLE and mild to moderate disease activity,” the authors wrote.
Impact of treatment
Researchers also examined the effect of treatments, and found that patients treated with hydroxychloroquine during the 1-year observation period had a 54% lower risk of subsequent death (95% CI, 0.29-0.72; P < .05) and a 70% lower risk of renal damage (95% CI, 0.13-0.68, P < .05). However, patients prescribed NSAIDs had a 66% higher risk of cardiovascular damage, while those who used any antihypertensive had an 81% higher risk of cardiovascular damage.
“This may suggest that the known cardiovascular risk of NSAIDs in the general population is also applicable to patients with SLE and highlights the importance of assessing cardiovascular risk in this patient population,” the authors wrote.
Smoking affected the risk of death: Smokers were 74% more likely to die during the follow-up period than were nonsmokers.
There were no significant differences between different ethnicities in the study. While White patients generally had lower disease activity overall, there was no significant differences in the risk of death or organ damage with ethnicity.
The Hopkins Lupus Cohort is supported by the National Institutes of Health, and the study was funded by GlaxoSmithKline. Three authors were paid employees of GlaxoSmithKline and two were paid consultants or contractors.

CDC panel: Pause of J&J COVID-19 vaccine to remain for now
The Advisory Committee on Immunization Practices decided there was not adequate information to change again recommend use of the Johnson & Johnson vaccine.
The committee’s decision comes the day after the CDC and Food and Drug Administration recommended that J&J injections be paused after reports of rare, but serious types of blood clots in six patients among the 6.8 million people who had received the J&J vaccine in the United States.
A member of the committee, Beth Bell, MD, said: “I do not want to be sending a message that there is some huge concern here on a different order of magnitude than any other vaccine safety signals that we evaluate. And I don’t want to send a message that there is something fundamentally wrong with the vaccine because that also I don’t agree with.”
At the end of the 4-hour meeting, ACIP members decided to call a meeting in 1 or 2 weeks and evaluate more safety data, specifically reports of people who have received the J&J vaccine in the past 2 weeks.
Some, however, pointed out that delaying a decision could have substantial consequences as well in terms of unused vaccine doses and public confidence.
Committee member Camiile Kotton, MD, described the pause as “devastating.”
“Putting this vaccine on pause for those of us that are frontline health care workers has really been devastating,” she said. “I agree in general that we don’t have enough data to make a decision at this time but we were planning on using this vaccine in the state of Massachusetts for people who were homebound and otherwise not able to get a vaccine. We were planning on using it for our vulnerable inpatient population often with many comorbidities and at high risk for disease but haven’t been able to get vaccinated otherwise.”
Pausing the one-and-done vaccine that doesn’t have the significant refrigeration requirements of the others “is a significant loss,” she said.
What is known, not known
Sara Oliver, MD, who leads the COVID-19 Vaccines ACIP Work Group, summarized what is known and unknown about the blood clots.
Among the six cases of cerebral venous sinus thrombosis reported to the Vaccine Adverse Event Reporting System after the J&J shot, all were women aged 18-48 years and all developed the clots 6-13 days after receiving the vaccine.
No cases of these clots have been reported from either the Pfizer or Moderna shots, she noted.
In the United States, the two mRNA vaccine alternatives – the Moderna and Pfizer vaccines – are available “and based on current projections supply of both vaccines are expected to be relatively stable in the near future,” she said.
She said 14 million doses of Pfizer and Moderna are expected each week in the United States and J&J vaccines makes up less than 5% of vaccines administered in the country.
Approximately 13 million J&J doses are available to order or are already at administration sites, she said.
But much more is unknown, she said.
“There may be more cases identified in the coming days to weeks,” Dr. Oliver said, referring back to the average time from vaccination to symptom onset.
Scott Ratzan, MD, editor-in-chief of the Journal of Health Communication: International Perspectives and executive director of Business Partners to CONVINCE (BP2C), a global network of employers that promotes COVID-19 vaccination among employees, suppliers, and customers, applauded ACIP’s delay on making a decision.
Dr. Ratzan, who watched the deliberations online, said in an interview the decision “shows an admirable abundance of caution in the distribution of COVID-19 vaccines.”
“Unfortunately,” he said, “the pause also worsens the existing and pervasive vaccine hesitancy issue.
“We need a rational strategy regarding who should or should not get the J&J/Janssen vaccine since these rare adverse events appear to affect a particular group of people, females aged 18-48. It is essential that we build vaccine confidence and retain the option of using this vaccine for people who are not in this risk group.”
He pointed out there are safety red flags with the Pfizer and Moderna COVID-19 vaccines.
“We should feel reassured about the process of ensuring vaccine safety as the FDA and CDC have quickly addressed risk and shared the data transparently of the J&J vaccine and taken appropriate action,” he said.
ACIP’s executive secretary, Amanda Cohn, MD, said the date for the next meeting would be set by April 16.

A member of the committee, Beth Bell, MD, said: “I do not want to be sending a message that there is some huge concern here on a different order of magnitude than any other vaccine safety signals that we evaluate. And I don’t want to send a message that there is something fundamentally wrong with the vaccine because that also I don’t agree with.”
At the end of the 4-hour meeting, ACIP members decided to call a meeting in 1 or 2 weeks and evaluate more safety data, specifically reports of people who have received the J&J vaccine in the past 2 weeks.
Some, however, pointed out that delaying a decision could have substantial consequences as well in terms of unused vaccine doses and public confidence.
Committee member Camiile Kotton, MD, described the pause as “devastating.”
“Putting this vaccine on pause for those of us that are frontline health care workers has really been devastating,” she said. “I agree in general that we don’t have enough data to make a decision at this time but we were planning on using this vaccine in the state of Massachusetts for people who were homebound and otherwise not able to get a vaccine. We were planning on using it for our vulnerable inpatient population often with many comorbidities and at high risk for disease but haven’t been able to get vaccinated otherwise.”
Pausing the one-and-done vaccine that doesn’t have the significant refrigeration requirements of the others “is a significant loss,” she said.
What is known, not known
Sara Oliver, MD, who leads the COVID-19 Vaccines ACIP Work Group, summarized what is known and unknown about the blood clots.
Among the six cases of cerebral venous sinus thrombosis reported to the Vaccine Adverse Event Reporting System after the J&J shot, all were women aged 18-48 years and all developed the clots 6-13 days after receiving the vaccine.
No cases of these clots have been reported from either the Pfizer or Moderna shots, she noted.
In the United States, the two mRNA vaccine alternatives – the Moderna and Pfizer vaccines – are available “and based on current projections supply of both vaccines are expected to be relatively stable in the near future,” she said.
She said 14 million doses of Pfizer and Moderna are expected each week in the United States and J&J vaccines makes up less than 5% of vaccines administered in the country.
Approximately 13 million J&J doses are available to order or are already at administration sites, she said.
But much more is unknown, she said.
“There may be more cases identified in the coming days to weeks,” Dr. Oliver said, referring back to the average time from vaccination to symptom onset.
Scott Ratzan, MD, editor-in-chief of the Journal of Health Communication: International Perspectives and executive director of Business Partners to CONVINCE (BP2C), a global network of employers that promotes COVID-19 vaccination among employees, suppliers, and customers, applauded ACIP’s delay on making a decision.
Dr. Ratzan, who watched the deliberations online, said in an interview the decision “shows an admirable abundance of caution in the distribution of COVID-19 vaccines.”
“Unfortunately,” he said, “the pause also worsens the existing and pervasive vaccine hesitancy issue.
“We need a rational strategy regarding who should or should not get the J&J/Janssen vaccine since these rare adverse events appear to affect a particular group of people, females aged 18-48. It is essential that we build vaccine confidence and retain the option of using this vaccine for people who are not in this risk group.”
He pointed out there are safety red flags with the Pfizer and Moderna COVID-19 vaccines.
“We should feel reassured about the process of ensuring vaccine safety as the FDA and CDC have quickly addressed risk and shared the data transparently of the J&J vaccine and taken appropriate action,” he said.
ACIP’s executive secretary, Amanda Cohn, MD, said the date for the next meeting would be set by April 16.

Seeing is bleeding, and smelling is perceiving
True Blood casting call!
If you’ve seen the show True Blood on HBO, you’re probably familiar with blood coming out instead of tears when any of the vampires start crying. Apparently, this interesting phenomenon isn’t unique to vampires on TV.
If you know about female anatomy, you know that the eyes aren’t usually involved in the menstrual cycle. However, a 25-year-old woman went to the ED when she experienced haemolacria, the term for blood tears, for the second time in 2 months during her cycle. She did not appear to have any injuries or illnesses that caused the eye bleeding, but physicians noted that both times she had eye bleeding, she also had her period.
Menstrual bleeding outside of the uterus, called vicarious menstruation, can occur, and it seems that the patient may have had that condition.
Since there are rumors of a True Blood remake circling, perhaps the show’s writers could blend in a little medical fact with vampire fiction.
What does skinny smell like? Lemons apparently
When you smell a lemon, what comes to your mind? How does it make you feel? Now think of the scent of vanilla. How does that one make you feel? Current research suggests certain smells may have an effect on how you perceive your body image.
Researchers from the University of Sussex (England) have found that certain olfactory stimuli (such as lemons and vanilla) and audio stimuli (light steps vs. heavy steps), have a moderate effect on self-image.
During their study, participants were put through a series of auditory and olfactory tests, from listening to stilettos and boots walking across the floor, to being exposed to certain essential oils with different sound pitches.
Exposure to lemon and higher-pitched sounds (like stilettos) made participants feel lighter and was associated with thin, spiky shapes. Exposure to vanilla and lower-pitched sounds was more associated with thicker, rounded shapes. This made researchers believe that multisensory stimuli, such as scents and sounds, can have a bigger role in treating eating disorders.
Our brain functions with multiple “mental models” of ourselves. Based on sensory stimuli from our day-to-day lives, those images and perceptions of ourselves change. Someone complimenting your snazzy new sweater provokes one self-perception, while someone letting you know that your fly is down provokes another.
Well, the researchers believe that, through a sense of smell, we can alter that perception of ourselves when paired with positive influence. Doing this through wearable “interactive clothes” could help boost the confidence and self-esteem of patients struggling with body image. Light smells equals light feelings. Of course, this won’t help the nearly 5% of the world who have some kind of smell disorder.
The researchers said that more research needs to be done, but you can do your own little experiment at home. Think about yourself and how you react to certain smells. How do they make you feel? If it makes you feel good, stop and smell more often.
Pregnancy with a side of pregnancy
It was a great day when Rebecca Roberts and her partner went to the obstetrician to confirm their positive pregnancy test. They’d been trying for more than a year without success, and now they would be having a baby. Note the usage of the singular there. That will become important in a moment.
When Ms. Roberts went back for her 12-week ultrasound appointment, there was an unexpected complication: Baby had become babies. The original fetus was there and doing fine, but there was now a second, less-developed fetus who’d invited herself in unannounced. While they were technically twins, the second fetus did not form at the same time, like normal fraternal twins, instead forming from an egg that was released weeks after the first egg was fertilized.
The phenomenon, called superfetation, is incredibly rare. Prior to 2008, there were fewer than 10 reported cases in the world, according to the European Journal of Obstetrics & Gynecology and Reproductive Biology. The odds of an egg being released during pregnancy, something that’s not supposed to happen, and then having that egg also become fertilized and successfully implanted in the uterus, is astronomically small.
It was not an easy pregnancy for Ms. Roberts, and at 33 weeks into the first pregnancy, the younger fetus’s umbilical cord began to malfunction, so delivery for both was induced in September 2020. Both infants spent time in the neonatal ICU, with the younger baby being in for 3 months, but after 6 months both are doing well and developing quickly. It’s always nice to have a happy ending to one of these weird medical phenomena, especially one with such an unpleasant-sounding name. If we didn’t know better, we’d think superfetation was something really, really smelly.
What’s a little misinformation among neighbors?
Vaccination will, hopefully, get the COVID-19 pandemic under control at some point, but the related misinformation floating around the Internet is another story. Already rampant in the United States, it’s now spreading … to Canada.
Investigators from that northern land took a look at the Twitter accounts of the platform’s 187,000 most active Canadian users and eventually ended up with a database of 147 million tweets, of which 154,000 contained terms associated with misinformation.
The Canadian social media users had more exposure to information from the United States than from Canada, and the exposure to U.S. outlets was more likely to involve misperceptions about COVID-19. “Most of the misinformation circulating on Twitter shared by Canadians was retweeted from U.S. sources,” the researchers said, and “Canadians who followed more American users were more likely to post misinformation.”
The study’s lead investigator, Aengus Bridgman of McGill University in Montreal, put it this way: “It’s hard for Canadian journalists, scientists, and public health experts to be heard by the average Canadian, given all the noise generated by American sources.”
People generally don’t take the time to read the fine print on contracts, and it looks like the Canadians have fallen into that trap. Not entirely their fault, of course, because most people coming from Canada to America don’t pass the Statue of Liberty, but she’s got some fine print of her own.
That poem written on the pedestal, the one that says, “Give me your tired, your poor, your huddled masses yearning to breathe free”? It’s actually a contract, and at the bottom, in very small print, it says, “In return for acceptance of the aforementioned ‘huddled masses,’ countries of origin agree to accept all of the social media noise generated by American sources.”
Sorry, Canada, but we gotcha.

How some COVID-19 vaccines could cause rare blood clots
on April 14, 2021, after the CDC and Food and Drug Administration recommended that states hold off on using it pending a detailed review of six cases of the same kind of rare but serious event – a blood clot in the vessels that drain blood from the brain combined with a large drop in platelets, which increases the risk for bleeding.
This combination can lead to severe strokes that can lead to brain damage or death. Among the six cases reported, which came to light over the past 3 weeks, one person died, according to the CDC. All six were women and ranged in age from 18 to 48 years.
According to a report from the Vaccine Adverse Event Reporting System (VAERS), which is maintained by the Department of Health & Human Services, the woman who died was 45. She developed a gradually worsening headache about a week after receiving the Johnson & Johnson vaccine.
On March 17, the day she came to the hospital, she was dry heaving. Her headache had suddenly gotten much worse, and the left side of her body was weak, which are signs of a stroke. A CT scan revealed both bleeding in her brain and a clot in her cortical vein. She died the following day.
In addition to VAERS, which accepts reports from anyone, the CDC and FDA are monitoring at least eight other safety systems maintained by hospitals, research centers, long-term care facilities, and insurance companies for signs of trouble with the vaccines. VAERS data is searchable and open to the public. Most of these systems are not publicly available to protect patient privacy. It’s unclear which systems detected the six cases cited by federal regulators.
“These are very serious and potentially fatal problems occurring in a healthy young adult. It’s serious and we need to get to the bottom of it,” said Ed Belongia, MD, director of the Center for Clinical Epidemiology and Population Health at the Marshfield (Wis.) Clinic Research Institute. Dr. Belongia leads a research team that helps the CDC monitor vaccine safety and effectiveness.
“Safety is always the highest priority, and I think what we’ve seen here in the past 24 hours is our vaccine safety monitoring system is working,” he said.
Others agree. “I think what CDC and FDA have detected is a rare, but likely real adverse event associated with this vaccine,” said Paul Offit, MD, director of vaccine education at Children’s Hospital of Philadelphia.
Although much is still unknown about these events, they follow a similar pattern of blood clots reported with the AstraZeneca vaccine in Europe. That vaccine is now sold under the brand name Vaxzevria.
This has experts questioning whether all vaccines of this type may cause these rare clots.
“I think it’s likely a class effect,” said Dr. Offit, who was a member of the FDA advisory committee that reviewed clinical trial data on the J&J vaccine before it was authorized for use.
Adenovirus vaccines scrutinized
Both the Johnson & Johnson and Vaxzevria vaccines use an adenovirus to ferry genetic instructions for making the coronaviruses spike protein into our cells.
Adenoviruses are common, relatively simple viruses that normally cause mild cold or flu symptoms. The ones used in the vaccine are disabled so they can’t make us sick. They’re more like Trojan horses.
Once inside our cells, they release the DNA instructions they carry to make the spike protein of the new coronavirus. Those cells then crank out copies of the spike protein, which then get displayed on the outer surface of the cell membrane where they are recognized by the immune system.
The immune system then makes antibodies and other defenses against the spike so that, when the real coronavirus comes along, our bodies are ready to fight the infection.
There’s no question the vaccine works. In clinical trials, the Johnson & Johnson vaccine was 66% percent effective at preventing against moderate to severe COVID-19 infection, and none of the patients who got COVID-19 after vaccination had to be admitted to the hospital or died.
The idea behind using adenoviruses in vaccines isn’t a new one. In a kind of fight-fire-with-fire approach, the idea is to use a virus, which is good at infecting us, to fight a different kind of virus.
Researchers have been working on the concept for about 10 years, but the COVID-19 vaccines that use this technology are some of the first adenovirus-vector vaccines deployed in humans.
Only one other adenovirus vaccine, for Ebola, has been approved for use in humans. It was approved in Europe last year. Before the Johnson & Johnson vaccine, no other adenovirus vector has been available for use in humans in the United States.
There are six adenovirus-vector vaccines for COVID-19. In addition to AstraZeneca and Johnson & Johnson, there’s the Russian-developed vaccine Sputnik V, along with CanSino from China, and the Covishield vaccine in India.
Adenovirus vaccines are more stable than the mRNA vaccines. That makes them easier to store and transport.
But they have a significant downside, too. Because adenoviruses infect humans out in the world, we already make antibodies against them. So there’s always a danger that our immune systems might recognize and react to the vaccine, rendering it ineffective. For that reason, scientists try to carefully select the adenovirus vectors, or carriers, they use.
The two vaccines under investigation for blood clots are slightly different. The Johnson & Johnson vaccine uses the vector AD26, because most of the population lacks preexisting immunity to it. Vaxzevria uses an adenovirus that infects chimpanzees, called ChAdOx1.
Vaxzevria has been widely used in Europe but has not yet been authorized in the United States.
On April 7, the European Medicines Agency, Europe’s counterpart to the FDA, ruled that unusual blood clots with low blood platelets should be listed as rare side effects on the Vaxzevria vaccine.
The decision came after reviewing 62 cases of cerebral venous sinus thrombosis (CVST) linked to the vaccine and 25 cases of another rare type of clot, called a splanchnic vein thrombosis. Splanchnic veins drain blood from the major organs in the digestive system, including the stomach, liver, and intestines; 18 of those events were fatal.
The reports were culled from reporting in Europe and the United Kingdom, where around 25 million people have received the Vaxzevria vaccine, making these clots exceptionally rare, but serious.
So far, six cases of CVST have been reported in the United States, after more than 7 million doses of the Johnson & Johnson vaccines have been administered.
A key question for U.S. regulators will be the background rate for these types of rare combinations of clots and deplenished platelets. The background rate is the number of events that would be expected to occur naturally in a population of unvaccinated people. On a press call on April 13, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, was asked about the frequency of this dangerous combination. He said the combination of low platelets and clots was so rare that it was hard to pinpoint, but might be somewhere between 2 and 14 cases per million people over the course of a year.
The first Johnson & Johnson doses were given in early March. That means the six cases came to light within the first few weeks of use of the vaccine in the United States, a very short amount of time.
“These were six cases per million people for 2 weeks, which is the same thing as 25 million per year, so it’s clearly above the background rate,” Dr. Offit said.
Studies suggest possible mechanism
On April 9, the New England Journal of Medicine published a detailed evaluation of the 11 patients in Germany and Austria who developed the rare clots after their Vaxzevria vaccines.
The study detected rare antibodies to a signaling protein called platelet factor 4, which helps to coordinate clot formation.
These same type of antibodies form in some people given the blood thinning drug heparin. In those reactions, which are also exceptionally rare, the same type of syndrome develops, leading to large, devastating clots that consume circulating platelets.
It’s not yet clear whether people who develop reactions to the vaccines already have some platelet factor 4 antibodies before they are vaccinated, or whether the vaccines somehow spur the body to make these antibodies, which then launch a kind of autoimmune attack.
The researchers on the paper gave the syndrome a name, vaccine-induced thrombotic thrombocytopenia (VITT).
It’s also not clear why more cases seem to be in women than in men. Andrew Eisenberger, MD, an associate professor of hematology and oncology at Columbia University, New York, said the most common causes of cerebral venous sinus thrombosis have to do with conditions that raise estrogen levels, like pregnancy and hormonal contraception.
“Estrogen naturally leads to changes in several clotting proteins in the blood that may predispose to abnormal blood clotting in a few different sites in the body,” he said. “The clotting changes we are encountering with some of COVID-19 vaccines are likely to be synergistic with the effects of estrogen on the blood.”
No matter the cause, the CDC on April 13 alerted doctors to keep a high index of suspicion for VITT in patients who have received the Johnson & Johnson vaccination within the last 2 weeks. In those patients, the usual course of treatment with blood thinning drugs like heparin may be harmful.
Symptoms to watch for include severe headache or backache, new neurologic symptoms, severe abdominal pain, shortness of breath, leg swelling, tiny red spots on the skin, or easy bruising.
Grappling with evidence
The CDC’s Advisory Committee on Immunization Practices will meet today in an emergency session to review the cases and see if any changes are needed to use of the J&J vaccine in the United States.
Last week, for example, the United Kingdom restricted the use of the AstraZeneca vaccine in people aged younger than 30 years, saying the risks and benefits of vaccination are “more finely balanced” for this age group.
With cases of COVID-19 rising again in the United States, and the Johnson & Johnson vaccine currently the most convenient form of protection against the virus, the committee will have to weigh the risks of that infection against the risk of rare clots caused by vaccination.
They will also likely have to rule out whether any of the cases had COVID. At least one study has reported CVST clots in three patients with confirmed COVID infections. In Europe, COVID infection did not seem to play a role in the formation of the clots with low platelets.
Hilda Bastian, PhD, a clinical trials expert who cofounded the Cochrane Collaboration, said it won’t be an easy task. Much will depend on how certain the committee members feel they know about all the events linked to the vaccine.
“That’s the really, really hard issue from my point of view for them right this moment. Have we missed any? Or how many are we likely to have missed?” asked Dr. Bastian, who lives in Australia.
“In a country that size with that fragmented [of] a health care system, how sure can you be that you know them all? That’s going to be a really difficult situation for them to grapple with, the quality of information that they’ve got,” she said.

on April 14, 2021, after the CDC and Food and Drug Administration recommended that states hold off on using it pending a detailed review of six cases of the same kind of rare but serious event – a blood clot in the vessels that drain blood from the brain combined with a large drop in platelets, which increases the risk for bleeding.
This combination can lead to severe strokes that can lead to brain damage or death. Among the six cases reported, which came to light over the past 3 weeks, one person died, according to the CDC. All six were women and ranged in age from 18 to 48 years.
According to a report from the Vaccine Adverse Event Reporting System (VAERS), which is maintained by the Department of Health & Human Services, the woman who died was 45. She developed a gradually worsening headache about a week after receiving the Johnson & Johnson vaccine.
On March 17, the day she came to the hospital, she was dry heaving. Her headache had suddenly gotten much worse, and the left side of her body was weak, which are signs of a stroke. A CT scan revealed both bleeding in her brain and a clot in her cortical vein. She died the following day.
In addition to VAERS, which accepts reports from anyone, the CDC and FDA are monitoring at least eight other safety systems maintained by hospitals, research centers, long-term care facilities, and insurance companies for signs of trouble with the vaccines. VAERS data is searchable and open to the public. Most of these systems are not publicly available to protect patient privacy. It’s unclear which systems detected the six cases cited by federal regulators.
“These are very serious and potentially fatal problems occurring in a healthy young adult. It’s serious and we need to get to the bottom of it,” said Ed Belongia, MD, director of the Center for Clinical Epidemiology and Population Health at the Marshfield (Wis.) Clinic Research Institute. Dr. Belongia leads a research team that helps the CDC monitor vaccine safety and effectiveness.
“Safety is always the highest priority, and I think what we’ve seen here in the past 24 hours is our vaccine safety monitoring system is working,” he said.
Others agree. “I think what CDC and FDA have detected is a rare, but likely real adverse event associated with this vaccine,” said Paul Offit, MD, director of vaccine education at Children’s Hospital of Philadelphia.
Although much is still unknown about these events, they follow a similar pattern of blood clots reported with the AstraZeneca vaccine in Europe. That vaccine is now sold under the brand name Vaxzevria.
This has experts questioning whether all vaccines of this type may cause these rare clots.
“I think it’s likely a class effect,” said Dr. Offit, who was a member of the FDA advisory committee that reviewed clinical trial data on the J&J vaccine before it was authorized for use.
Adenovirus vaccines scrutinized
Both the Johnson & Johnson and Vaxzevria vaccines use an adenovirus to ferry genetic instructions for making the coronaviruses spike protein into our cells.
Adenoviruses are common, relatively simple viruses that normally cause mild cold or flu symptoms. The ones used in the vaccine are disabled so they can’t make us sick. They’re more like Trojan horses.
Once inside our cells, they release the DNA instructions they carry to make the spike protein of the new coronavirus. Those cells then crank out copies of the spike protein, which then get displayed on the outer surface of the cell membrane where they are recognized by the immune system.
The immune system then makes antibodies and other defenses against the spike so that, when the real coronavirus comes along, our bodies are ready to fight the infection.
There’s no question the vaccine works. In clinical trials, the Johnson & Johnson vaccine was 66% percent effective at preventing against moderate to severe COVID-19 infection, and none of the patients who got COVID-19 after vaccination had to be admitted to the hospital or died.
The idea behind using adenoviruses in vaccines isn’t a new one. In a kind of fight-fire-with-fire approach, the idea is to use a virus, which is good at infecting us, to fight a different kind of virus.
Researchers have been working on the concept for about 10 years, but the COVID-19 vaccines that use this technology are some of the first adenovirus-vector vaccines deployed in humans.
Only one other adenovirus vaccine, for Ebola, has been approved for use in humans. It was approved in Europe last year. Before the Johnson & Johnson vaccine, no other adenovirus vector has been available for use in humans in the United States.
There are six adenovirus-vector vaccines for COVID-19. In addition to AstraZeneca and Johnson & Johnson, there’s the Russian-developed vaccine Sputnik V, along with CanSino from China, and the Covishield vaccine in India.
Adenovirus vaccines are more stable than the mRNA vaccines. That makes them easier to store and transport.
But they have a significant downside, too. Because adenoviruses infect humans out in the world, we already make antibodies against them. So there’s always a danger that our immune systems might recognize and react to the vaccine, rendering it ineffective. For that reason, scientists try to carefully select the adenovirus vectors, or carriers, they use.
The two vaccines under investigation for blood clots are slightly different. The Johnson & Johnson vaccine uses the vector AD26, because most of the population lacks preexisting immunity to it. Vaxzevria uses an adenovirus that infects chimpanzees, called ChAdOx1.
Vaxzevria has been widely used in Europe but has not yet been authorized in the United States.
On April 7, the European Medicines Agency, Europe’s counterpart to the FDA, ruled that unusual blood clots with low blood platelets should be listed as rare side effects on the Vaxzevria vaccine.
The decision came after reviewing 62 cases of cerebral venous sinus thrombosis (CVST) linked to the vaccine and 25 cases of another rare type of clot, called a splanchnic vein thrombosis. Splanchnic veins drain blood from the major organs in the digestive system, including the stomach, liver, and intestines; 18 of those events were fatal.
The reports were culled from reporting in Europe and the United Kingdom, where around 25 million people have received the Vaxzevria vaccine, making these clots exceptionally rare, but serious.
So far, six cases of CVST have been reported in the United States, after more than 7 million doses of the Johnson & Johnson vaccines have been administered.
A key question for U.S. regulators will be the background rate for these types of rare combinations of clots and deplenished platelets. The background rate is the number of events that would be expected to occur naturally in a population of unvaccinated people. On a press call on April 13, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, was asked about the frequency of this dangerous combination. He said the combination of low platelets and clots was so rare that it was hard to pinpoint, but might be somewhere between 2 and 14 cases per million people over the course of a year.
The first Johnson & Johnson doses were given in early March. That means the six cases came to light within the first few weeks of use of the vaccine in the United States, a very short amount of time.
“These were six cases per million people for 2 weeks, which is the same thing as 25 million per year, so it’s clearly above the background rate,” Dr. Offit said.

How to counsel worried patients about the J&J vaccine news
On April 13, the Centers for Disease Control and Prevention and the Food and Drug Administration issued a joint statement recommending a pause in Johnson & Johnson vaccine administration, pending review of six reported U.S. cases of a rare and severe type of blood clot occurring after receiving the Johnson & Johnson vaccine. To date, more than 6.8 million doses of that vaccine have been given in the United States, so at this point the rate of detected cases of this problem is less than one in a million.
The six cases occurred in women aged 18-48 years, and symptoms occurred 6-13 days after vaccination. In these cases, cerebral venous sinus thrombosis was seen in addition to thrombocytopenia.
Physicians may receive calls from concerned patients who have received a COVID vaccine. However, more than 95% of the vaccine administrations in the United States to date have been the Pfizer and Moderna messenger RNA vaccines. No association between these vaccines and blood clots has been detected. Also, these six cases occurred within 2 weeks of Johnson & Johnson vaccination, so even among those receiving the Johnson & Johnson vaccine, those who are more than 3 weeks out from their vaccination have no need for concern regarding this rare complication.
Physicians should counsel those who have received the Johnson & Johnson vaccine less than 3 weeks ago to watch for easy bruising, gum bleeding, nose bleeds, leg or arm pain or swelling, severe headache or abdominal pain, shortness of breath, or chest pain. If they notice one or more of those symptoms, they should seek medical attention.
The Centers for Disease Control and Prevention will convene a meeting of the Advisory Committee on Immunization Practices on April 14 to review the six U.S. cases of the Johnson & Johnson vaccine and determine their significance.
Several cases of unusual thromboses and thrombocytopenia have been detected after the Oxford AstraZeneca vaccine, which uses the same adenovirus vector technology as the Johnson & Johnson vaccine, but which is not authorized for use in the United States. The Oxford AstraZeneca vaccine uses a recombinant deficient chimpanzee adenovirus to deliver the message to cells to produce antibody against the SARS-CoV-2 spike protein. The Johnson & Johnson vaccine uses a recombinant deficient human adenovirus to deliver this same message.
Two recent reports in the New England Journal of Medicine have reported on thrombosis and thrombocytopenia after the Oxford AstraZeneca vaccine in Europe. Both of these reports identified high levels of IgG antibodies to platelet factor 4–polyanion complexes, similar to the mechanism of heparin-induced thrombocytopenia. The term vaccine-induced immune thrombocytopenia was proposed for this phenomenon. Treatment of this condition involves administration of intravenous immunoglobulin and nonheparin anticoagulants. Recent updates from the World Health Organization report that 169 cases of cerebral venous sinus thrombosis and 53 of splanchnic venous thrombosis occurred after 34 million doses of the Oxford AstraZeneca vaccine was administered in the European Union and United Kingdom.
While this pause in Johnson & Johnson vaccination is disappointing news amid increased cases in parts of the country, the Johnson & Johnson vaccines make up less than 5% of the U.S. vaccine doses administered to date. According to the CDC, more than 122 million Americans have received at least one dose and more than 75 million are fully vaccinated.
Dr. Patterson has received an honorarium from Pfizer for an antifungal symposium and is a subinvestigator for the Novavax vaccine. Her spouse served as a consultant for SCYNEXIS, as a speaker for Gilead Sciences and Basilea, and has received a research grant from the National Institutes of Health for the ACTT remdesivir trial.

Data about COVID-19-related skin manifestations in children continue to emerge
Two and stratifying children at risk for serious, systemic illness due to the virus.
In a single-center descriptive study carried out over a 9-month period, researchers in Madrid found that of 50 hospitalized children infected with COVID-19, 21 (42%) had mucocutaneous symptoms, most commonly exanthem, followed by conjunctival hyperemia without secretion and red cracked lips or strawberry tongue. In addition, 18 (36%) fulfilled criteria for Multisystem Inflammatory Syndrome in Children (MIS-C).
“Based on findings in adult patients, the skin manifestations of COVID-19 have been classified under five categories: acral pseudo-chilblain, vesicular eruptions, urticarial lesions, maculopapular eruptions, and livedo or necrosis,” David Andina-Martinez, MD, of Hospital Infantil Universitario Niño Jesús, Madrid, and colleagues wrote in the study, which was published online on April 2 in the Journal of the American Academy of Dermatology.
“Chilblain lesions in healthy children and adolescents have received much attention; these lesions resolve without complications after a few weeks,” they added. “Besides, other cutaneous manifestations of COVID-19 in children have been the matter of case reports or small case series. Nevertheless, the mucocutaneous manifestations in hospitalized children infected with SARS-CoV-2 and their implications on the clinical course have not yet been extensively described.”
In an effort to describe the mucocutaneous manifestations in children hospitalized for COVID-19, the researchers evaluated 50 children up to 18 years of age who were admitted between March 1 and Nov. 30, 2020, to Hospital Infantil Universitario Niño Jesús, which was designated as a pediatric reference center during the peak of the pandemic. The main reasons for admission were respiratory illness (40%) and MIS-C (40%).
Of the 50 patients, 44 (88%) had a positive RT-PCR for SARS-CoV-2 and 6 (12%) met clinical suspicion criteria and had a negative RT-PCR with a positive IgG serology. In 34 patients (68%), a close contact with a suspected or confirmed case of COVID-19 was referred, while the source of the infection remained unknown in the remaining 16 patients (32%).
The researchers reported that 21 patients (42%) had mucocutaneous symptoms, most commonly maculopapular exanthem (86%), conjunctival hyperemia (81%), and red cracked lips or strawberry tongue (43%). In addition, 18 of the 21 patients (86%) fulfilled criteria for MIS-C.
“A tricky thing about MIS-C is that it often manifests 4-5 weeks after a child had COVID-19,” said Christine Ko, MD, professor of dermatology and pathology at Yale University, New Haven, Conn., who was asked to comment on the study. “MIS-C is associated with characteristic bright red lips and a red tongue that might resemble a strawberry. Such oral findings should prompt rapid evaluation for other signs and symptoms. There can be redness of the eyes or other more nonspecific skin findings (large or small areas of redness on the trunk or limbs, sometimes with surface change), but more importantly, fever, a rapid heartbeat, diarrhea, or breathing issues. The risk with MIS-C is a rapid decline in a child’s health, with admission to an intensive care unit.”
Dr. Andina-Martinez and his colleagues also contrast the skin findings of MIS-C, which are not generally on the hands or feet, with the so-called “COVID toe” or finger phenomenon, which has also been associated with SARS-CoV-2, particularly in children. “Only one of the patients in this series had skin involvement of a finger, and it only appeared after recovery from MIS-C,” Dr. Ko noted. “Distinguishing COVID toes from MIS-C is important, as COVID toes has a very good outcome, while MIS-C can have severe consequences, including protracted heart disease.”
In other findings, patients who presented with mucocutaneous signs tended to be older than those without skin signs and they presented at the emergency department with poor general status and extreme tachycardia. They also had higher C-reactive protein and D-dimer levels and lower lymphocyte counts and faced a more than a 10-fold increased risk of being admitted to the PICU, compared with patients who did not have skin signs (OR, 10.24; P = .003).
In a separate study published online on April 7 in JAMA Dermatology, Zachary E. Holcomb, MD, of the combined dermatology residency program at Massachusetts General Hospital, Boston, and colleagues presented what is believed to be the first case report of reactive infectious mucocutaneous eruption (RIME) triggered by SARS-CoV-2. RIME is the preferred term for pediatric patients who present with mucositis and rash (often a scant or even absent skin eruption) triggered by various infectious agents.
The patient, a 17-year-old male, presented to the emergency department with 3 days of mouth pain and nonpainful penile erosions. “One week prior, he experienced transient anosmia and ageusia that had since spontaneously resolved,” the researchers wrote. “At that time, he was tested for SARS-CoV-2 infection via nasopharyngeal polymerase chain reaction (PCR), the results of which were positive.”
At presentation, the patient had no fever, his vital signs were normal, and the physical exam revealed shallow erosions of the vermilion lips and hard palate, circumferential erythematous erosions of the periurethral glans penis, and five small vesicles on the trunk and upper extremities. Serum analysis revealed a normal white blood cell count with mild absolute lymphopenia, slightly elevated creatinine level, normal liver function, slightly elevated C-reactive protein level, and normal ferritin level.
Dr. Holcomb and colleagues made a diagnosis of SARS-CoV-2–associated RIME based on microbiological results, which revealed positive repeated SARS-CoV-2 nasopharyngeal PCR and negative nasopharyngeal PCR testing for Mycoplasma pneumoniae, adenovirus, Chlamydophila pneumoniae, human metapneumovirus, influenza A/B, parainfluenza 1 to 4, rhinovirus, and respiratory syncytial virus. In addition, titers of Mycoplasma pneumoniae IgM levels were negative, but Mycoplasma pneumoniae IgG levels were elevated.
The lesions resolved with 60 mg of oral prednisone taken daily for 4 days. A recurrence of oral mucositis 3 months later responded to 80 mg oral prednisone taken daily for 6 days.
“It’s not surprising that SARS-CoV-2 is yet another trigger for RIME,” said Anna Yasmine Kirkorian, MD, chief of the division of dermatology at Children’s National Hospital, Washington, who was asked to comment about the case report.
“The take-home message is for clinicians to be aware of this association and distinguish these patients from those with MIS-C, because patients with MIS-C require monitoring and urgent systemic treatment. RIME and MIS-C may potentially be distinguished clinically based on the nature of the mucositis (hemorrhagic and erosive in RIME, dry, cracked lips with ‘strawberry tongue’ in MIS-C) but more importantly patients with RIME lack laboratory evidence of severe systemic inflammation,” such as ESR, CRP, or ferritin, she said.
“A final interesting point in this article was the recurrence of mucositis in this patient, which could mean that recurrent mucositis/recurrent RIME might be yet another manifestation of ‘long-COVID’ (now called post-Acute Sequelae of SARS-CoV-2 infection) in some patients,” Dr. Kirkorian added. She noted that the American Academy of Dermatology–International League of Dermatologic Societies COVID-19 Dermatology Registry and articles like these “provide invaluable ‘hot off the presses’ information for clinicians who are facing the protean manifestations of a novel viral epidemic.”
The researchers reported having no financial disclosures.

Arthritis drug may curb myocardial damage in acute STEMI
Early use of tocilizumab (Actemra) does not reduce myocardial infarct size but modestly increases myocardial salvage in patients with acute ST-segment elevation MI (STEMI), results of the ASSAIL-MI trial suggest.
“We’re among the first to show that you can actually affect the reperfusion injury through anti-inflammatory treatment – it’s sort of a new attack point for treatments in STEMI,” lead author Kaspar Broch, MD, PhD, Oslo University Hospital Rikshospitalet, said in an interview. “What we do now is reperfuse as soon as we can and then add drugs in order to prevent new events, but we don’t really attack the reperfusion injury that occurs when you perform PCI [percutaneous coronary intervention], which has been shown to actually account for some 50% of the final injury.”
The phase 2, proof-of-concept study was prompted by the team’s earlier work in non-STEMI patients, in which a single dose of the interleukin-6 receptor antagonist cut C-reactive protein (CRP) levels by more than 50% during hospitalization and reduced troponin T release after PCI.
For ASSAIL-MI, Dr. Broch and colleagues randomly assigned 199 patients presenting with acute STEMI within 6 hours of symptom onset to a single intravenous injection of 280 mg tocilizumab or placebo during PCI. Patients, study personnel, and caretakers were blinded to treatment. Data were available for 195 patients for the primary endpoint of myocardial salvage index.
As reported in the Journal of the American College of Cardiology, tocilizumab was associated with a higher adjusted myocardial salvage index on cardiac MRI 3-7 days after PCI than placebo (69.3% vs. 63.6%; P = .04).
The extent of microvascular obstruction was less with tocilizumab (0% vs. 4%; P = .03), as was the area under the curve of CRP during hospitalization (1.9 vs. 8.6 mg/L per hour; P < .001).
The final infarct size at 6 months was 21% lower in the tocilizumab group but the difference did not reach statistical significance (7.2% vs. 9.1% of left ventricular mass; P = .08).
There were no between-group differences in troponin T area under the curve during hospitalization (1,614 vs. 2,357 ng/L per hour; P = .13), N-terminal of the prohormone brain natriuretic peptide concentrations at 6 months (79 vs. 63 ng/L; P = .25), or baseline-adjusted left ventricular end-diastolic volume at 6 months (157 vs. 160 mL; P = .54).
Subgroup analyses suggested the positive effect of tocilizumab on myocardial salvage index is limited to patients presenting at least 3 hours after symptom onset versus 3 hours or less (P = .034), with a trend for greater benefit among men versus women (P = .053).
Dr. Broch noted that the absolute effect of tocilizumab on myocardial necrosis was smaller than anticipated when the trial was designed, which may explain the lack of significant reduction in infarct size.
“We were aiming for patients with larger infarctions than we actually ended up with, which is partly due to the strict inclusion criteria and the fact that, with modern treatments, patients don’t end up with large myocardial infarctions,” he said. “But if they had been larger, I think that 20% absolute reduction would have meant a lot in terms of clinical events.”
The study also used a very modest dose of tocilizumab, compared with that used for inflammatory diseases, to minimize a potential negative effect on myocardial healing, for instance, myocardial ruptures, Dr. Broch said. “I’m not sure whether you gain anything by giving a larger dose.”
Serious adverse events were similar in the tocilizumab and placebo groups (19 vs. 15; P = .57). There were no myocardial ruptures, and no patient died or developed heart failure. LDL cholesterol, triglycerides, and liver enzymes increased in the tocilizumab group but were similar at 3 and 6 months.
“IL-6 is a central cytokine involved in all stages of plaque growth, progression, and rupture,” Paul Ridker, MD, MPH, of the Brigham and Women’s Hospital in Boston, and a long-standing investigator in inflammation and atherothrombosis, said in an interview. “These preliminary data in STEMI, like the authors’ prior data in non-STEMI, are consistent with the idea that inhibiting IL-6 could have clinical benefit, a concept that will be taken into a major cardiovascular outcomes trial later this year.”
The cardiovascular outcomes trial, known as ZEUS, will test the novel IL-6 inhibitor ziltivekimab among more than 6,000 very-high-risk atherosclerosis patients who have moderate to severe chronic kidney disease and high sensitivity CRP greater than 2 mg/L, he noted.
Moving beyond IL-1b blockade as done in CANTOS to direct downstream inhibition of IL-6 represents a “logical next scientific step” in the development of anti-inflammatory therapies for acute ischemia and chronic atherosclerosis, Dr. Ridker, who led the CANTOS trial, noted in an accompanying editorial.
“Preventive cardiologists, however, need not wait until outcome trials are complete to use this evolving biological knowledge to their patient’s advantage,” he wrote. “As recently confirmed in the pages of the Journal, exercise, smoking cessation, and a healthy diet reduce both C-reactive protein and IL-6, and clearly have lifelong benefits. Our immediate task is thus to incorporate inflammation inhibition through lifestyle management into our daily practice.”
The study was supported by the South-Eastern Norway Regional Health Authority, Central Norway Regional Health Authority, and Roche, which provided the medicinal products and an unrestricted grant. Dr. Broch has disclosed no relevant financial relationships. Dr. Ridker has received investigator-initiated research grant support from Kowa, Novartis, Amarin, Pfizer, and the National Heart, Lung, and Blood Institute; and has served as a consultant to Novartis, Janssen, Agepha, Flame, Civi Biopharma, Inflazome, Corvidia, Novo Nordisk, SOCAR, IQVIA, and AstraZeneca.

“We’re among the first to show that you can actually affect the reperfusion injury through anti-inflammatory treatment – it’s sort of a new attack point for treatments in STEMI,” lead author Kaspar Broch, MD, PhD, Oslo University Hospital Rikshospitalet, said in an interview. “What we do now is reperfuse as soon as we can and then add drugs in order to prevent new events, but we don’t really attack the reperfusion injury that occurs when you perform PCI [percutaneous coronary intervention], which has been shown to actually account for some 50% of the final injury.”
The phase 2, proof-of-concept study was prompted by the team’s earlier work in non-STEMI patients, in which a single dose of the interleukin-6 receptor antagonist cut C-reactive protein (CRP) levels by more than 50% during hospitalization and reduced troponin T release after PCI.
For ASSAIL-MI, Dr. Broch and colleagues randomly assigned 199 patients presenting with acute STEMI within 6 hours of symptom onset to a single intravenous injection of 280 mg tocilizumab or placebo during PCI. Patients, study personnel, and caretakers were blinded to treatment. Data were available for 195 patients for the primary endpoint of myocardial salvage index.
As reported in the Journal of the American College of Cardiology, tocilizumab was associated with a higher adjusted myocardial salvage index on cardiac MRI 3-7 days after PCI than placebo (69.3% vs. 63.6%; P = .04).
The extent of microvascular obstruction was less with tocilizumab (0% vs. 4%; P = .03), as was the area under the curve of CRP during hospitalization (1.9 vs. 8.6 mg/L per hour; P < .001).
The final infarct size at 6 months was 21% lower in the tocilizumab group but the difference did not reach statistical significance (7.2% vs. 9.1% of left ventricular mass; P = .08).
There were no between-group differences in troponin T area under the curve during hospitalization (1,614 vs. 2,357 ng/L per hour; P = .13), N-terminal of the prohormone brain natriuretic peptide concentrations at 6 months (79 vs. 63 ng/L; P = .25), or baseline-adjusted left ventricular end-diastolic volume at 6 months (157 vs. 160 mL; P = .54).
Subgroup analyses suggested the positive effect of tocilizumab on myocardial salvage index is limited to patients presenting at least 3 hours after symptom onset versus 3 hours or less (P = .034), with a trend for greater benefit among men versus women (P = .053).
Dr. Broch noted that the absolute effect of tocilizumab on myocardial necrosis was smaller than anticipated when the trial was designed, which may explain the lack of significant reduction in infarct size.
“We were aiming for patients with larger infarctions than we actually ended up with, which is partly due to the strict inclusion criteria and the fact that, with modern treatments, patients don’t end up with large myocardial infarctions,” he said. “But if they had been larger, I think that 20% absolute reduction would have meant a lot in terms of clinical events.”
The study also used a very modest dose of tocilizumab, compared with that used for inflammatory diseases, to minimize a potential negative effect on myocardial healing, for instance, myocardial ruptures, Dr. Broch said. “I’m not sure whether you gain anything by giving a larger dose.”
Serious adverse events were similar in the tocilizumab and placebo groups (19 vs. 15; P = .57). There were no myocardial ruptures, and no patient died or developed heart failure. LDL cholesterol, triglycerides, and liver enzymes increased in the tocilizumab group but were similar at 3 and 6 months.
“IL-6 is a central cytokine involved in all stages of plaque growth, progression, and rupture,” Paul Ridker, MD, MPH, of the Brigham and Women’s Hospital in Boston, and a long-standing investigator in inflammation and atherothrombosis, said in an interview. “These preliminary data in STEMI, like the authors’ prior data in non-STEMI, are consistent with the idea that inhibiting IL-6 could have clinical benefit, a concept that will be taken into a major cardiovascular outcomes trial later this year.”
The cardiovascular outcomes trial, known as ZEUS, will test the novel IL-6 inhibitor ziltivekimab among more than 6,000 very-high-risk atherosclerosis patients who have moderate to severe chronic kidney disease and high sensitivity CRP greater than 2 mg/L, he noted.
Moving beyond IL-1b blockade as done in CANTOS to direct downstream inhibition of IL-6 represents a “logical next scientific step” in the development of anti-inflammatory therapies for acute ischemia and chronic atherosclerosis, Dr. Ridker, who led the CANTOS trial, noted in an accompanying editorial.
“Preventive cardiologists, however, need not wait until outcome trials are complete to use this evolving biological knowledge to their patient’s advantage,” he wrote. “As recently confirmed in the pages of the Journal, exercise, smoking cessation, and a healthy diet reduce both C-reactive protein and IL-6, and clearly have lifelong benefits. Our immediate task is thus to incorporate inflammation inhibition through lifestyle management into our daily practice.”
The study was supported by the South-Eastern Norway Regional Health Authority, Central Norway Regional Health Authority, and Roche, which provided the medicinal products and an unrestricted grant. Dr. Broch has disclosed no relevant financial relationships. Dr. Ridker has received investigator-initiated research grant support from Kowa, Novartis, Amarin, Pfizer, and the National Heart, Lung, and Blood Institute; and has served as a consultant to Novartis, Janssen, Agepha, Flame, Civi Biopharma, Inflazome, Corvidia, Novo Nordisk, SOCAR, IQVIA, and AstraZeneca.

The obesity risk everyone forgets
Clinicians in pediatrics have noticed a troubling pattern emerge during the pandemic, something that is darkly referred to as “the COVID 19,” or the 19 or more pounds that many of our patients have gained in the past year. This phenomenon has underscored many maxims in pediatric weight management: Mainly that frequent snacking, decreased physical activity, and less parental supervision lead to increased weight gain. But could we be missing another lesson this trend is teaching us? What about the relationship between catastrophe and childhood obesity?
Beyond the increased weight gain with lockdowns, I have observed other evidence in my own practice that childhood trauma or adverse experiences increase obesity. Our electronic medical record system gives an alert when a chart with sensitive information is accessed. One example might be if the patient had been seen at a clinic for children who have been abused. I am heartbroken at how often this happens. Academically, I understand the dire statistics about the incidence of child abuse, but the frequency at which I see this pattern is jarring.
Over the years, one striking correlation became clear among my patient population: Children with obesity were more likely to have been seen in the child abuse clinic than normal-weight peers.
I am far from the only one to have observed this relationship. Television shows focusing on severe obesity, such as “My 600-Pound Life,” often show trauma as both a cause and effect of severe obesity. This theme also became apparent on the show “The Biggest Loser,” which highlighted the difficulty of achieving and maintaining substantial weight loss. If even Hollywood has noticed this association, shouldn’t we be much farther ahead?
Pathways to obesity
Adverse childhood experiences (ACE) encompass various causes of child trauma, including abuse or neglect; poverty; household or neighborhood violence; and death, illness, or incarceration of a parent. A pivotal report in 1998 formalized the suspicion that many of us could plainly see: People who suffered ACE have higher incidence of heart disease, COPD, liver disease, incarceration, and drug abuse. For those with six or more ACE, life expectancy averaged 20 years less than those who had none. More recently, a meta-analysis found an odds ratio of 1.46 for adult obesity with known history of childhood trauma.
As a pediatric endocrinologist living in the poorest state of the country, I have clearly observed the correlation between childhood obesity and poverty. While prior generations may have associated child poverty with malnutrition and starvation, we are seeing in modern times that obesity has become a disease of lack. Calorie-dense and processed foods tend to be less expensive, more shelf-stable, and more accessible to people living in both urban and rural food deserts.
I am also a foster mother and have received extensive training in parenting children who have lived through trauma and neglect. For children who have endured food scarcity and deprivation, hoarding food and overeating are expected responses.
But the pathways to abnormal weight gain are myriad and expand beyond binge eating or numbing with food. ACE are particularly troubling because they affect developing brains and the neuroendocrine system; they alter epigenetics and cause heritable changes. Structural brain differences have been evident in the frontopolar cortex, which is linked to centers in the hypothalamus that control appetite. And increased stress raises cortisol release, increases insulin resistance, and alters satiety.
Shifting our approach to treatment
The significant cost of ACE is enormous and affects us all. Health professionals in pediatrics must understand these connections to effectively counsel children and their families dealing with obesity. Handing someone a diet plan and lecturing them about weight loss is never effective, but this common tactic is especially cruel if we do not assess for and address underlying pain. Obviously, blame and shame are ineffective motivators for lifestyle change in any circumstance, but these tactics may be especially harmful in the light of childhood trauma.
Screening for ACE is important in every aspect of pediatric care. The presence of obesity, however, should remind us to be more sensitive to the possibility of causative trauma. Clinicians for adults are not off the hook either. Fully 60% of adults suffered ACE and are dealing with the aftermath.
To improve health outcomes across the board, we must screen for trauma and become educated on trauma-informed care. Perhaps the most important first referral for a child suffering ACE and obesity is to a trained counselor or a social worker. Shepherding children through trauma will be more effective for attaining healthy weight than any remedy I can prescribe as an endocrinologist. Furthermore, this is our necessary role as healers. More than ever, we need to approach chronic diseases, including obesity, with the utmost compassion.

Medtronic recall of almost 240,000 ICDs is class I, FDA says
The Food and Drug Administration has declared Medtronic’s recall of seven models of defibrillating cardiac rhythm devices, caused by a risk for premature battery depletion, as class I, which implies a potential risk for serious injury or death. A total of 444 complaints, but no deaths, have been reported in association with the 239,171 affected devices, the agency said in a statement on April 12, 2021.
Physicians were notified of the company’s recall in early February. It covered implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy–defibrillator (CRT-D) models Evera, Viva, Brava, Claria, Amplia, Compia, and Visia distributed from Aug. 31, 2012 to May 9, 2018.
The devices could be subject to “an unexpected and rapid decrease in battery life” because of a possible short circuit that could lead to a device-replacement alert “earlier than expected.” Some devices may experience full battery depletion “within as little as 1 day” after such an alert.
“If the user does not respond to the first warning, the device may stop functioning. The likelihood that this issue will occur is constant after approximately 3 years after device use,” the announcement said.
Medtronic recommends device replacement no more than 1 week after such an early warning for patients who are not pacing dependent or who have them for primary prevention, but right away for pacing-dependent patients.
