Phase 3 trial findings compared outcomes for COPD patients who had triple fixed-dose inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta2 agonist with patients who received one of two dual-therapy combinations. The results were presented at the American Thoracic Society’s virtual clinical trial session.

A total of 8,509 patients were randomized on a 1:1:1:1 basis to receive twice daily:

  • Single-inhaler combinations of the inhaled corticosteroid (ICS) budesonide at one of two doses, the long-acting muscarinic antagonist (LAMA) glycopyrrolate, and the long-acting beta2 agonist (LABA) formoterol.
  • Dual-therapy combination glycopyrrolate and formoterol.
  • Dual-therapy combination budesonide and formoterol.

The annual rate of moderate or severe COPD exacerbations was 1.08 and 1.07 for the triple combinations with 320 mcg and 180 mcg doses of budesonide, respectively, compared with 1.42 for glycopyrrolate-formoterol, and 1.24 for budesonide-formoterol.

Both triple combinations were significantly superior to the dual therapies for controlling exacerbations, reported Klaus F. Rabe, MD, PhD, from LungenClinic Grosshansdorf and Christian-Albrechts University Kiel (Germany), and colleagues in the ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial (NCT02465567).

“Our findings show the benefits of triple therapy with a budesonide-glycopyrrolate-formoterol combination over dual therapy with a LAMA-LABA or an inhaled glucocorticoid-LABA combination with respect to the annual rate of moderate or severe COPD exacerbations, symptoms, and health-related quality of life in patients with moderate to very-severe COPD who are at risk of exacerbations,” they wrote in a study published online in the New England Journal of Medicine..

The trial showed for the first time that “triple therapy that has half the dose of steroid compared to a standard ICS/LABA combination has had greater efficacy for the exacerbation endpoint,” Dr. Rabe said during his presentation.

Triple-therapy combinations with an ICS, LAMA, and LABA are recommended for patients with COPD who remain symptomatic or experience further exacerbations on dual–ICS/LABA or –LAMA/LABA combinations. The triple combinations have been shown in several studies to lower risk of exacerbations and are associated with both better lung function and health-related quality of life, compared with dual therapies, the investigators noted.

However, concerns about adverse events associated with long-term ICS use – including pneumonia, cataracts, and increased fracture risk, possibly related to treatment duration, dose level, or type of corticosteroid used – spurred the ETHOS investigators to compare triple and dual fixed-dose combinations for efficacy and safety over 1 year.
 

Large study

They enrolled 8,509 adults aged 40-80 years with symptomatic COPD (defined as score of 10 or higher on the 40-point COPD Assessment Test). All patients were receiving at least two inhaled maintenance therapies at the time of screening, and had a postbronchodilator ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity of less than 0.7, with a postbronchodilator FEV1 of 25%-65% of the predicted normal value. The patients all had a smoking history of at least 10 pack-years and a documented history of at least one moderate or severe COPD exacerbation in the year before screening.

The patients were randomized in equal proportions to receive triple therapy with budesonide at 320- or 160-mcg doses plus glycopyrrolate 18 mcg, and formoterol 9.6 mcg twice daily, or to dual therapy with either glycopyrrolate plus formoterol at the same doses, or 320 mcg budesonide plus 9.6 mcg formoterol.

As noted, for the primary endpoint of the estimated annual rate of moderate or severe exacerbations, the triple combinations were associated with significantly lower rates, with a 24% lower rate (rate ratio, 0.76) with 320 mcg budesonide triple therapy, compared with glycopyrrolate-formoterol, and a 13% lower rate (RR, 0.87), compared with budesonide formoterol (P < .001 and P = .003, respectively).

The triple combination with the 160-mcg budesonide dose was associated with a 25% lower annual rate of exacerbations (RR, 0.75) vs. glycopyrrolate-formoterol, and a 14% lower rate (RR, 0.86) vs. budesonide-formoterol (P < .001 and P = .002, respectively).

Secondary efficacy endpoints also favored the triple combination, including a 20% lower rate ratio of severe exacerbations over 52 weeks for the 320-mcg budesonide group, compared with the budesonide-formoterol group (P = .02).

The 320-mcg dose combination was also associated with a 46% lower risk for all-cause mortality, compared with glycopyrrolate-formoterol (hazard ratio, 0.54; P = .0111).

Confirmed pneumonia was seen in 4.2% of patients on the 320-mcg budesonide dose, 3.5% of those in the 160-mcg group, and 4.5% of patients treated with budesonide-formoterol. The incidence of any adverse effect was similar across the treatment groups, ranging from 61.7% to 64.5%.
 

Balance exacerbation, pneumonia risk

In the question-and-answer session following his online presentation, Dr. Rabe was asked how the investigators reconciled their data showing increased incidence of pneumonia in budenoside-containing formulations with claims by the maker of the budesonide-formoterol (Symbicort, AstraZeneca) that budesonide is not associated with increased risk of pneumonia.

“We have to say that there are individuals that we have to balance the benefit of [less] exacerbation against the risk of pneumonia,” he replied, but noted that the size of the effect, observed both in ETHOS and in the KRONOS trial, was relatively small.

“This definitely adds some information for us to think about when we’re trying to do risk-benefit analysis,” commented MeiLan K. Han, MD, MS, from the University of Michigan, who moderated the session but was not involved in the study.

The ETHOS trial was funded by AstraZeneca. Dr. Rabe disclosed consulting/advisory board activity with that company and others. Dr. Han has previously disclosed consulting/advising and research funding relationships with other companies.

Three stages to COVID-19 brain damage, new review suggests

Article Type
Changed
Thu, 12/15/2022 - 15:44

A new review outlined a three-stage classification of the impact of COVID-19 on the central nervous system and recommended all hospitalized patients with the virus undergo MRI to flag potential neurologic damage and inform postdischarge monitoring.

In stage 1, viral damage is limited to epithelial cells of the nose and mouth, and in stage 2 blood clots that form in the lungs may travel to the brain, leading to stroke. In stage 3, the virus crosses the blood-brain barrier and invades the brain.

“Our major take-home points are that patients with COVID-19 symptoms, such as shortness of breath, headache, or dizziness, may have neurological symptoms that, at the time of hospitalization, might not be noticed or prioritized, or whose neurological symptoms may become apparent only after they leave the hospital,” lead author Majid Fotuhi, MD, PhD, medical director of NeuroGrow Brain Fitness Center in McLean, Va., said.

“Hospitalized patients with COVID-19 should have a neurological evaluation and ideally a brain MRI before leaving the hospital; and, if there are abnormalities, they should follow up with a neurologist in 3-4 months,” said Dr. Fotuhi, who is also affiliate staff at Johns Hopkins Medicine, Baltimore.

The review was published online June 8 in the Journal of Alzheimer’s Disease.
 

Wreaks CNS havoc

It has become “increasingly evident” that SARS-CoV-2 can cause neurologic manifestations, including anosmia, seizures, stroke, confusion, encephalopathy, and total paralysis, the authors wrote.

They noted that SARS-CoV-2 binds to ACE2, which facilitates the conversion of angiotensin II to angiotensin. After ACE2 has bound to respiratory epithelial cells and then to epithelial cells in blood vessels, SARS-CoV-2 triggers the formation of a “cytokine storm.”

These cytokines, in turn, increase vascular permeability, edema, and widespread inflammation, as well as triggering “hypercoagulation cascades,” which cause small and large blood clots that affect multiple organs.

If SARS-CoV-2 crosses the blood-brain barrier, directly entering the brain, it can contribute to demyelination or neurodegeneration.

“We very thoroughly reviewed the literature published between Jan. 1 and May 1, 2020, about neurological issues [in COVID-19] and what I found interesting is that so many neurological things can happen due to a virus which is so small,” said Dr. Fotuhi.

“This virus’ DNA has such limited information, and yet it can wreak havoc on our nervous system because it kicks off such a potent defense system in our body that damages our nervous system,” he said.
 

Three-stage classification

  • Stage 1: The extent of SARS-CoV-2 binding to the ACE2 receptors is limited to the nasal and gustatory epithelial cells, with the cytokine storm remaining “low and controlled.” During this stage, patients may experience smell or taste impairments, but often recover without any interventions.
  • Stage 2: A “robust immune response” is activated by the virus, leading to inflammation in the blood vessels, increased hypercoagulability factors, and the formation of blood clots in cerebral arteries and veins. The patient may therefore experience either large or small strokes. Additional stage 2 symptoms include fatigue, hemiplegia, sensory loss, , tetraplegia, , or ataxia.
  • Stage 3: The cytokine storm in the blood vessels is so severe that it causes an “explosive inflammatory response” and penetrates the blood-brain barrier, leading to the entry of cytokines, blood components, and viral particles into the brain parenchyma and causing neuronal cell death and encephalitis. This stage can be characterized by seizures, confusion, , coma, loss of consciousness, or death.
 

 

“Patients in stage 3 are more likely to have long-term consequences, because there is evidence that the virus particles have actually penetrated the brain, and we know that SARS-CoV-2 can remain dormant in neurons for many years,” said Dr. Fotuhi.

“Studies of coronaviruses have shown a link between the viruses and the risk of multiple sclerosis or Parkinson’s disease even decades later,” he added.

“Based on several reports in recent months, between 36% to 55% of patients with COVID-19 that are hospitalized have some neurological symptoms, but if you don’t look for them, you won’t see them,” Dr. Fotuhi noted.

As a result, patients should be monitored over time after discharge, as they may develop cognitive dysfunction down the road.

Additionally, “it is imperative for patients [hospitalized with COVID-19] to get a baseline MRI before leaving the hospital so that we have a starting point for future evaluation and treatment,” said Dr. Fotuhi.

“The good news is that neurological manifestations of COVID-19 are treatable,” and “can improve with intensive training,” including lifestyle changes – such as a heart-healthy diet, regular physical activity, stress reduction, improved sleep, biofeedback, and brain rehabilitation, Dr. Fotuhi added.
 

Routine MRI not necessary

Kenneth Tyler, MD, chair of the department of neurology at the University of Colorado at Denver, Aurora, disagreed that all hospitalized patients with COVID-19 should routinely receive an MRI.

“Whenever you are using a piece of equipment on patients who are COVID-19 infected, you risk introducing the infection to uninfected patients,” he said. Instead, “the indication is in patients who develop unexplained neurological manifestations – altered mental status or focal seizures, for example – because in those cases, you do need to understand whether there are underlying structural abnormalities,” said Dr. Tyler, who was not involved in the review.

Also commenting on the review, Vanja Douglas, MD, associate professor of clinical neurology, University of California, San Francisco, described the review as “thorough” and suggested it may “help us understand how to design observational studies to test whether the associations are due to severe respiratory illness or are specific to SARS-CoV-2 infection.”

Dr. Douglas, who was not involved in the review, added that it is “helpful in giving us a sense of which neurologic syndromes have been observed in COVID-19 patients, and therefore which patients neurologists may want to screen more carefully during the pandemic.”

The study had no specific funding. Dr. Fotuhi disclosed no relevant financial relationships. One coauthor reported receiving consulting fees as a member of the scientific advisory board for Brainreader and reports royalties for expert witness consultation in conjunction with Neurevolution. Dr. Tyler and Dr. Douglas disclosed no relevant financial relationships.

A new review outlined a three-stage classification of the impact of COVID-19 on the central nervous system and recommended all hospitalized patients with the virus undergo MRI to flag potential neurologic damage and inform postdischarge monitoring.

In stage 1, viral damage is limited to epithelial cells of the nose and mouth, and in stage 2 blood clots that form in the lungs may travel to the brain, leading to stroke. In stage 3, the virus crosses the blood-brain barrier and invades the brain.

“Our major take-home points are that patients with COVID-19 symptoms, such as shortness of breath, headache, or dizziness, may have neurological symptoms that, at the time of hospitalization, might not be noticed or prioritized, or whose neurological symptoms may become apparent only after they leave the hospital,” lead author Majid Fotuhi, MD, PhD, medical director of NeuroGrow Brain Fitness Center in McLean, Va., said.

“Hospitalized patients with COVID-19 should have a neurological evaluation and ideally a brain MRI before leaving the hospital; and, if there are abnormalities, they should follow up with a neurologist in 3-4 months,” said Dr. Fotuhi, who is also affiliate staff at Johns Hopkins Medicine, Baltimore.

The review was published online June 8 in the Journal of Alzheimer’s Disease.
 

Wreaks CNS havoc

It has become “increasingly evident” that SARS-CoV-2 can cause neurologic manifestations, including anosmia, seizures, stroke, confusion, encephalopathy, and total paralysis, the authors wrote.

They noted that SARS-CoV-2 binds to ACE2, which facilitates the conversion of angiotensin II to angiotensin. After ACE2 has bound to respiratory epithelial cells and then to epithelial cells in blood vessels, SARS-CoV-2 triggers the formation of a “cytokine storm.”

These cytokines, in turn, increase vascular permeability, edema, and widespread inflammation, as well as triggering “hypercoagulation cascades,” which cause small and large blood clots that affect multiple organs.

If SARS-CoV-2 crosses the blood-brain barrier, directly entering the brain, it can contribute to demyelination or neurodegeneration.

“We very thoroughly reviewed the literature published between Jan. 1 and May 1, 2020, about neurological issues [in COVID-19] and what I found interesting is that so many neurological things can happen due to a virus which is so small,” said Dr. Fotuhi.

“This virus’ DNA has such limited information, and yet it can wreak havoc on our nervous system because it kicks off such a potent defense system in our body that damages our nervous system,” he said.
 

Three-stage classification

  • Stage 1: The extent of SARS-CoV-2 binding to the ACE2 receptors is limited to the nasal and gustatory epithelial cells, with the cytokine storm remaining “low and controlled.” During this stage, patients may experience smell or taste impairments, but often recover without any interventions.
  • Stage 2: A “robust immune response” is activated by the virus, leading to inflammation in the blood vessels, increased hypercoagulability factors, and the formation of blood clots in cerebral arteries and veins. The patient may therefore experience either large or small strokes. Additional stage 2 symptoms include fatigue, hemiplegia, sensory loss, , tetraplegia, , or ataxia.
  • Stage 3: The cytokine storm in the blood vessels is so severe that it causes an “explosive inflammatory response” and penetrates the blood-brain barrier, leading to the entry of cytokines, blood components, and viral particles into the brain parenchyma and causing neuronal cell death and encephalitis. This stage can be characterized by seizures, confusion, , coma, loss of consciousness, or death.
 

 

“Patients in stage 3 are more likely to have long-term consequences, because there is evidence that the virus particles have actually penetrated the brain, and we know that SARS-CoV-2 can remain dormant in neurons for many years,” said Dr. Fotuhi.

“Studies of coronaviruses have shown a link between the viruses and the risk of multiple sclerosis or Parkinson’s disease even decades later,” he added.

“Based on several reports in recent months, between 36% to 55% of patients with COVID-19 that are hospitalized have some neurological symptoms, but if you don’t look for them, you won’t see them,” Dr. Fotuhi noted.

As a result, patients should be monitored over time after discharge, as they may develop cognitive dysfunction down the road.

Additionally, “it is imperative for patients [hospitalized with COVID-19] to get a baseline MRI before leaving the hospital so that we have a starting point for future evaluation and treatment,” said Dr. Fotuhi.

“The good news is that neurological manifestations of COVID-19 are treatable,” and “can improve with intensive training,” including lifestyle changes – such as a heart-healthy diet, regular physical activity, stress reduction, improved sleep, biofeedback, and brain rehabilitation, Dr. Fotuhi added.
 

Routine MRI not necessary

Kenneth Tyler, MD, chair of the department of neurology at the University of Colorado at Denver, Aurora, disagreed that all hospitalized patients with COVID-19 should routinely receive an MRI.

“Whenever you are using a piece of equipment on patients who are COVID-19 infected, you risk introducing the infection to uninfected patients,” he said. Instead, “the indication is in patients who develop unexplained neurological manifestations – altered mental status or focal seizures, for example – because in those cases, you do need to understand whether there are underlying structural abnormalities,” said Dr. Tyler, who was not involved in the review.

Also commenting on the review, Vanja Douglas, MD, associate professor of clinical neurology, University of California, San Francisco, described the review as “thorough” and suggested it may “help us understand how to design observational studies to test whether the associations are due to severe respiratory illness or are specific to SARS-CoV-2 infection.”

Dr. Douglas, who was not involved in the review, added that it is “helpful in giving us a sense of which neurologic syndromes have been observed in COVID-19 patients, and therefore which patients neurologists may want to screen more carefully during the pandemic.”

The study had no specific funding. Dr. Fotuhi disclosed no relevant financial relationships.

Phase 3 COVID-19 vaccine trials launching in July, expert says

Article Type

Thu, 08/26/2021 - 16:04

The race to develop a SARS-CoV-2 vaccine is unlike any other global research and development effort in modern medicine.

Dr. Paul A. Offit

According to Paul A. Offit, MD, there are now 120 Investigational New Drug applications to the Food and Drug Administration for these vaccines, and researchers at more than 70 companies across the globe are interested in making a vaccine. The Biomedical Advanced Research and Development Authority (BARDA) has awarded $2.5 billion to five different pharmaceutical companies to make a vaccine.

“The good news is that the new coronavirus is relatively stable,” Dr. Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, said during the virtual Pediatric Dermatology 2020: Best Practices and Innovations Conference. “Although it is a single-stranded RNA virus, it does mutate to some extent, but it doesn’t look like it’s going to mutate away from the vaccine. So, this is not going to be like influenza virus, where you must give a vaccine every year. I think we can make a vaccine that will last for several years. And we know the protein we’re interested in. We’re interested in antibodies directed against the spike glycoprotein, which is abundantly present on the surface of the virus. We know that if we make an antibody response to that protein, we can therefore prevent infection.”

Some research groups are interested in developing a whole, killed virus like those used in the inactivated polio vaccine, and vaccines for hepatitis A virus and rabies, said Dr. Offit, who is a member of Accelerating COVID-19 Technical Innovations And Vaccines, a public-private partnership formed by the National Institutes of Health. Other groups are interested in making a live-attenuated vaccine like those for measles, mumps, and rubella. “Some are interested in using a vectored vaccine, where you take a virus that is relatively weak and doesn’t cause disease in people, like vesicular stomatitis virus, and then clone into that the gene that codes for this coronavirus spike protein, which is the way that we made the Ebola virus vaccine,” Dr. Offit said. “Those approaches have all been used before, with success.”

Novel approaches are also being employed to make this vaccine, including using a replication-defective adenovirus. “That means that the virus can’t reproduce itself, but it can make proteins,” he explained. “There are some proteins that are made, but most aren’t. Therefore, the virus can’t reproduce itself. We’ll see whether or not that [approach] works, but it’s never been used before.”

Another approach is to inject messenger RNA that codes for the coronavirus spike protein, where that genetic material is translated into the spike protein. The other platform being evaluated is a DNA vaccine, in which “you give DNA which is coded for that spike protein, which is transcribed to messenger RNA and then is translated to other proteins.”

Typical vaccine development involves animal models to prove the concept, dose-ranging studies in humans, and progressively larger safety and immunogenicity studies in hundreds of thousands of people. Next come phase 3 studies, “where the proof is in the pudding,” he said. “These are large, prospective placebo-controlled trials to prove that the vaccine is safe. This is the only way whether you can prove or not a vaccine is effective.”



According to Dr. Offit, the phase 3 COVID-19 vaccine trials supported by BARDA will launch in July 2020 and will enroll 20,000 people in the vaccine treatment arm and 10,000 in the placebo arm. “Some companies may branch out on their own and do smaller studies than that,” he said. “We’ll see how this plays out. Keep your eyes open for that, because you really want to make sure you have a fairly large phase 3 trial. That’s the best way to show whether something works and whether it’s safe.”

The tried and true vaccines that emerge from the effort will not be FDA-licensed products. Rather, they will be approved products under the Emergency Use Authorization program. “Ever since the 1950s, every vaccine that has been used in the U.S. has been under the auspices of FDA licensure,” said Dr. Offit, who is also professor of pediatrics and the Maurice R. Hilleman professor of vaccinology at the University of Pennsylvania, Philadelphia. “That’s not going to be true here. The FDA is involved every step of the way but here they have a somewhat lighter touch.”

A few candidate vaccines are being mass-produced at risk, “meaning they’re being produced not knowing whether these vaccines are safe and effective yet or not,” he said. “But when they’re shown in a phase 3 trial to be safe and effective, you will have already produced it, and then it’s much easier to roll it out to the general public the minute you’ve shown that it works. This is what we did for the polio vaccine back in the 1950s. We mass-produced that vaccine at risk.”

Dr. Offit emphasized the importance of managing expectations once a COVID-19 vaccine gets approved for use. “Regarding safety, these vaccines will be tested in tens of thousands of people, not tens of millions of people, so although you can disprove a relatively uncommon side effect preapproval, you’re not going to disprove a rare side effect preapproval. You’re only going to know that post approval. I think we need to make people aware of that and to let them know that through groups like the Vaccine Safety Datalink, we’re going to be monitoring these vaccines once they’re approved.”

Regarding efficacy, he continued, “we’re not going know about the rates of immunity initially; we’re only going to know about that after the vaccine [has been administered]. My guess is the protection is going to be short lived and incomplete. By short lived, I mean that protection would last for years but not decades. By incomplete, I mean that protection will be against moderate to severe disease, which is fine. You don’t need protection against all of the disease; it’s hard to do that with respiratory viruses. That means you can keep people out of the hospital, and you can keep them from dying. That’s the main goal.”

Dr. Offit closed his remarks by noting that much is at stake in this effort to develop a vaccine so quickly and that it “could go one of two ways. We could find that the vaccine is a lifesaver, and [that] we can finally end this awful pandemic. Or, if we cut corners and don’t prove that the vaccines are safe and effective as we should before they’re released, we could shake what is a fragile vaccine confidence in this country. Hopefully, it doesn’t play out that way.”

Skin patterns of COVID-19 vary widely

Article Type
Changed
Thu, 08/26/2021 - 16:04

There are at least five dermatologic patterns in patients who are suspected or confirmed of having COVID-19, and the knowledge base continues to evolve, according to Christine Ko, MD.

Dr. Christine Ko

“Things are very fluid,” Dr. Ko, professor of dermatology and pathology at Yale University, New Haven, Conn., said during the virtual annual meeting of the American Academy of Dermatology. “New studies are coming out daily. Due to the need for rapid dissemination, a lot of the studies are case reports, but there are some nice case series. Another caveat for the literature is that a lot of these cases were not necessarily confirmed with testing for SARS-CoV-2, but some were.”

Dr. Ko framed her remarks largely on a case collection survey of images and clinical data from 375 patients in Spain with suspected or confirmed COVID-19 that was published online April 29, 2020, in the British Journal of Dermatology (doi: 10.1111/bjd.19163). Cutaneous manifestations included early vesicular eruptions mainly on the trunk or limbs (9%), maculopapular (47%) to urticarial lesions (19%) mainly on the trunk, and acral areas of erythema sometimes with vesicles or erosion (perniosis-like) (19%) that seemed to be a later manifestation of COVID-19. Retiform purpura or necrosis (6%) was most concerning in terms of skin disease, with an associated with a mortality of 10%.



On histology, the early vesicular eruptions are typically marked by dyskeratotic keratinocytes, Dr. Ko said, while urticarial lesions are characterized by a mixed dermal infiltrate; maculopapular lesions were a broad category. “There are some case reports that show spongiotic dermatitis or parakeratosis with a lymphocytic infiltrate,” she said. “A caveat to keep in mind is that, although these patients may definitely have COVID-19 and be confirmed to have it by testing, hypersensitivity reactions may be due to the multiple medications they’re on.”

Patients can develop a spectrum of lesions that are suggestive of vascular damage or occlusion, Dr. Ko continued. Livedoid lesions may remain static and not eventuate into necrosis or purpura but will self-resolve. Purpuric lesions and acral gangrene have been described, and these lesions correspond to vascular occlusion on biopsy.

A later manifestation are the so-called “COVID toes” with a superficial and deep lymphocytic infiltrate, as published June 1, 2020, in JAAD Case Reports: (doi: 10.1016/j.jdcr.2020.04.011).

“There are patients in the literature that have slightly different pathology, with lymphocytic inflammation as well as occlusion of vessels,” Dr. Ko said. A paper published June 20, 2020, in the British Journal of Dermatology used immunohistochemical staining against the SARS-CoV-2 spike protein, and biopsies of “COVID toes” had positive staining of endothelial cells, supporting the notion that “COVID toes” are a direct manifestation of viral infection (doi: 10.1111/bjd.19327).

“There’s a lot that we still don’t know, and some patterns are going to be outliers,” Dr. Ko concluded. “[As for] determining which skin manifestations are directly from coronavirus infection within the skin, more study is needed and likely time will tell.” She reported having no financial disclosures relevant to her talk.

Another caveat for the literature is that a lot of these cases were not necessarily confirmed with testing for SARS-CoV-2, but some were.”

Dr. Ko framed her remarks largely on a case collection survey of images and clinical data from 375 patients in Spain with suspected or confirmed COVID-19 that was published online April 29, 2020, in the British Journal of Dermatology (doi: 10.1111/bjd.19163). Cutaneous manifestations included early vesicular eruptions mainly on the trunk or limbs (9%), maculopapular (47%) to urticarial lesions (19%) mainly on the trunk, and acral areas of erythema sometimes with vesicles or erosion (perniosis-like) (19%) that seemed to be a later manifestation of COVID-19. Retiform purpura or necrosis (6%) was most concerning in terms of skin disease, with an associated with a mortality of 10%.



On histology, the early vesicular eruptions are typically marked by dyskeratotic keratinocytes, Dr. Ko said, while urticarial lesions are characterized by a mixed dermal infiltrate; maculopapular lesions were a broad category. “There are some case reports that show spongiotic dermatitis or parakeratosis with a lymphocytic infiltrate,” she said. “A caveat to keep in mind is that, although these patients may definitely have COVID-19 and be confirmed to have it by testing, hypersensitivity reactions may be due to the multiple medications they’re on.”

Patients can develop a spectrum of lesions that are suggestive of vascular damage or occlusion, Dr. Ko continued. Livedoid lesions may remain static and not eventuate into necrosis or purpura but will self-resolve. Purpuric lesions and acral gangrene have been described, and these lesions correspond to vascular occlusion on biopsy.

A later manifestation are the so-called “COVID toes” with a superficial and deep lymphocytic infiltrate, as published June 1, 2020, in JAAD Case Reports: (doi: 10.1016/j.jdcr.2020.04.011).

“There are patients in the literature that have slightly different pathology, with lymphocytic inflammation as well as occlusion of vessels,” Dr. Ko said. A paper published June 20, 2020, in the British Journal of Dermatology used immunohistochemical staining against the SARS-CoV-2 spike protein, and biopsies of “COVID toes” had positive staining of endothelial cells, supporting the notion that “COVID toes” are a direct manifestation of viral infection (doi: 10.1111/bjd.19327).

“There’s a lot that we still don’t know, and some patterns are going to be outliers,” Dr. Ko concluded. “[As for] determining which skin manifestations are directly from coronavirus infection within the skin, more study is needed and likely time will tell.” She reported having no financial disclosures relevant to her talk.

How racism contributes to the effects of SARS-CoV-2

Article Type

Thu, 08/26/2021 - 16:04

t’s been about two months since I volunteered in a hospital in Brooklyn, working in an ICU taking care of patients with COVID-19. I’m back home in California now but with new perspectives, not only on the pandemic, but on those who are affected by it the most.

Everyone seems to have forgotten the early days of the pandemic – the time when the ICUs were overrun, we were using FEMA ventilators, and endocrinologists and psychiatrists were acting as intensivists.

Even though things are opening up and people are taking summer vacations in a seemingly amnestic state, having witnessed multiple daily deaths remains a part of my daily consciousness. As I see the case numbers climbing juxtaposed against people being out and about without masks, my anxiety level is rising.

A virus doesn’t discriminate. It can fly through the air, landing on the next available surface. If that virus is SARS-CoV-2 and that surface is a human mucosal membrane, the virus makes itself at home. It orders furniture, buys a fancy mattress and a large high definition TV, hangs art on the walls, and settles in for the long haul. It’s not going anywhere anytime soon.

Even as an equal opportunity virus, what SARS-CoV-2 has done is to hold a mirror up to the healthcare system. It has shown us what was here all along. When people first started noticing that underrepresented minorities were more likely to contract the virus and get sick from it, I heard musings that this was likely because of their preexisting health conditions. For example, commentators on cable news were quick to point out that black people are more likely than other people to have hypertension or diabetes. So doesn’t that explain why they are more affected by this virus?

That certainly is part of the story, but it doesn’t entirely explain the discrepancies we’ve seen. For example, in New York 14% of the population is black, and 25% of those who had a COVID-related death were black patients. Similarly, 19% of the population is Hispanic or Latino, and they made up 26% of COVID-related deaths. On the other hand, 55% of the population in New York is white, and white people account for only 34% of COVID-related deaths.

Working in Brooklyn, I didn’t need to be a keen observer to notice that, out of our entire unit of about 20-25 patients, there was only one patient in a 2-week period who was neither black nor Hispanic.

As others have written, there are other factors at play. I’m not sure how many of those commentators back in March stopped to think about why black patients are more likely to have hypertension and diabetes, but the chronic stress of facing racism on a daily basis surely contributes. Beyond those medical problems, minorities are more likely to live in multigenerational housing, which means that it is harder for them to isolate from others. In addition, their living quarters tend to be further from health care centers and grocery stores, which makes it harder for them to access medical care and healthy food.



As if that weren’t enough to put their health at risk, people of color are also affected by environmental racism . Factories with toxic waste are more likely to be built in or near neighborhoods filled with people of color than in other communities. On top of that, black and Hispanic people are also more likely to be under- or uninsured, meaning they often delay seeking care in order to avoid astronomic healthcare costs.

Black and Hispanic people are also more likely than others to be working in the service industry or other essential services, which means they are less likely to be able to work from home. Consequently, they have to risk more exposures to other people and the virus than do those who have the privilege of working safely from home. They also are less likely to have available paid leave and, therefore, are more likely to work while sick.

With the deck completely stacked against them, underrepresented minorities also face systemic bias and racism when interacting with the health care system. Physicians mistakenly believe black patients experience less pain than other patients, according to some research. Black mothers have significantly worse health care outcomes than do their non-black counterparts, and the infant mortality rate for Black infants is much higher as well.

In my limited time in Brooklyn, taking care of almost exclusively black and Hispanic patients, I saw one physician assistant and one nurse who were black; one nurse practitioner was Hispanic. This mismatch is sadly common. Although 13% of the population of the United States is black, only 5% of physicians in the United States are black. Hispanic people, who make up 18% of the US population, are only 6% of physicians. This undoubtedly contributes to poorer outcomes for underrepresented minority patients who have a hard time finding physicians who look like them and understand them.

So while SARS-CoV-2 may not discriminate, the effects it has on patients depends on all of these other factors. If it flies through the air and lands on the mucosal tract of a person who works from home, has effective health insurance and a primary care physician, and lives in a community with no toxic exposures, that person may be more likely to kick it out before it has a chance to settle in. The reason we have such a huge disparity in outcomes related to COVID-19 by race is that a person meeting that description is less likely to be black or Hispanic. Race is not an independent risk factor; structural racism is.

When I drive by the mall that is now open or the restaurants that are now open with indoor dining, my heart rate quickens just a bit with anxiety. The pandemic fatigue people are experiencing is leading them to act in unsafe ways – gathering with more people, not wearing masks, not keeping a safe distance. I worry about everyone, sure, but I really worry about black and Hispanic people who are most vulnerable as a result of everyone else’s refusal to follow guidelines.

ACIP plans priority groups in advance of COVID-19 vaccine

Article Type

Thu, 08/26/2021 - 16:04

Early plans for prioritizing vaccination when a COVID-19 vaccine becomes available include placing critical health care workers in the first tier, according to Sarah Mbaeyi, MD, MPH, of the Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases.

A COVID-19 vaccine work group is developing strategies and identifying priority groups for vaccination to help inform discussions about the use of COVID-19 vaccines, Dr. Mbaeyi said at a virtual meeting of the CDC’s Advisory Committee on Immunization Practices.

“Preparing for vaccination during a pandemic has long been a priority of the CDC and the U.S. government,” said Dr. Mbaeyi. The work group is building on a tiered approach to vaccination that was updated in 2018 after the H1N1 flu pandemic, with occupational and high-risk populations placed in the highest-priority groups, Dr. Mbaeyi said.

There are important differences between COVID-19 and influenza, Dr. Mbaeyi said. “Vaccine prioritization is challenging due to incomplete information on COVID-19 epidemiology and vaccines, including characteristics, timing, and number of doses.”

However, guidance for vaccine prioritization developed after the H1N1 outbreak in 2018 can be adapted for COVID-19.

To help inform ACIP deliberations, the work group reviewed the epidemiology of COVID-19. A large proportion of the population remains susceptible, and prioritizations should be based on data to date and continually refined, she said.

The work group defined the objectives of the COVID-19 vaccine program as follows: “Ensure safety and effectiveness of COVID-19 vaccines; reduce transmission, morbidity, and mortality in the population; help minimize disruption to society and economy, including maintaining health care capacity; and ensure equity in vaccine allocation and distribution.”

Based on current information, the work group has proposed that vaccine priority be given to health care personnel, essential workers, adults aged 65 years and older, long-term care facility residents, and persons with high-risk medical conditions.

Among these groups “a subset of critical health care and other workers should receive initial doses,” Dr. Mbaeyi said.

However, vaccines will not be administered until safety and efficacy have been demonstrated, she emphasized. The timing and number of vaccine doses are unknown, and subprioritization may be needed, assuming the vaccine becomes available in incremental quantities over several months.

Next steps for the work group are refinement of priority groups based on ACIP feedback, and assignment of tiers to other groups such as children, pregnant women, and racial/ethnic groups at high risk, Dr. Mbaeyi said.

The goal of the work group is to have a prioritization framework for COVID-19 vaccination to present at the next ACIP meeting.

Committee member Helen Keipp Talbot, MD, of Vanderbilt University, Nashville, Tenn., emphasized that “one of the things we need to know is how is the virus [is] transmitted and who is transmitting,” and that this information will be key to developing strategies for vaccination.

Sarah E. Oliver, MD, an epidemiologist at the National Center for Immunization and Respiratory Diseases, responded that household transmission studies are in progress that will help inform the prioritization process.

Dr. Mbaeyi and Dr. Oliver had no financial conflicts to disclose.

Black women at highest risk for asthma

Article Type
Changed
Mon, 06/29/2020 - 09:36

Women are much more likely than men to have asthma, and asthma rates among black women are higher than for other races/ethnicities, according to the Centers for Disease Control and Prevention.

Among all women aged 18 years and older, 9.7% reported that they currently had asthma in 2017-2018, compared with 5.5% of men, based on age-adjusted data from the National Health Interview Survey.

The proportion of black, non-Hispanic women with asthma, however, was even higher, at 11.4%. White non-Hispanic women were next at 10.3%, followed by Hispanic (7.8%) and Asian (5.0%) women, the CDC reported June 26 in the Morbidity and Mortality Weekly Report.

The same pattern held for men: 6.2% of black men had asthma in 2017-2018, compared with 5.9% of whites, 3.9% of Hispanics, and 3.3% of Asian men, the CDC said.

The same pattern held for men: 6.2% of black men had asthma in 2017-2018, compared with 5.9% of whites, 3.9% of Hispanics, and 3.3% of Asian men, the CDC said.

COVID-19: ‘dramatic’ surge in out-of-hospital cardiac arrests in NYC

Thu, 08/26/2021 - 16:04

 

The COVID-19 pandemic in New York City led to a surge in out-of-hospital cardiac arrests (OHCAs) that placed a huge burden on first responders, a new analysis shows.

During the height of the pandemic in New York, there was a “dramatic increase in cardiopulmonary arrests, nearly all presented in non-shockable cardiac rhythms (> 90% fatality rate) and vulnerable patient populations were most affected,” David J. Prezant, MD, chief medical officer, Fire Department of New York (FDNY), said in an interview.

In a news release, Dr. Prezant noted that “relatively few, if any, patients were tested to confirm the presence of COVID-19,” making it impossible to distinguish between cardiac arrests as a result of COVID-19 and those that may have resulted from other health conditions.

“We also can’t rule out the possibility that some people may have died from delays in seeking or receiving treatment for non–COVID-19-related conditions. However, the dramatic increase in cardiac arrests compared to the same period in 2019 strongly indicates that the pandemic was directly or indirectly responsible for that surge in cardiac arrests and deaths,” said Dr. Prezant.

The study was published online June 19 in JAMA Cardiology.



New York City has the largest and busiest EMS system in the United States, serving a population of more than 8.4 million people and responding to more than 1.5 million calls every year.

To gauge the impact of COVID-19 on first responders, Dr. Prezant and colleagues analyzed data for adults with OHCA who received EMS resuscitation from March 1, when the first case of COVID-19 was diagnosed in the city, through April 25, when EMS call volume had receded to pre-COVID-19 levels.

Compared with the same period in 2019, the COVID-19 period had an excess of 2,653 patients with OHCA who underwent EMS resuscitation attempts (3,989 in 2020 vs. 1,336 in 2019, P < .001), an incidence rate triple that of 2019 (47.5 vs. 15.9 per 100,000).

On the worst day – Monday, April 6 – OHCAs peaked at 305 cases, an increase of nearly 10-fold compared with the same day in 2019.

Despite the surge in cases, the median response time of available EMS units to OHCAs increased by about 1 minute over 2019, a nonsignificant difference. Although the average time varied, median response time during the COVID-19 period was less than 3 minutes.

A more vulnerable group

Compared with 2019, patients suffering OHCA during the pandemic period were older (mean age 72 vs. 68 years), less likely to be white (20% white vs. 33%) and more likely to have hypertension (54% vs. 46%), diabetes (36% vs. 26%), physical limitations (57% vs. 48%) and cardiac rhythms that don’t respond to defibrillator shocks (92% vs. 81%).

Compared with 2019, the COVID-19 period had substantial reductions in return of spontaneous circulation (ROSC) (18% vs. 35%; P < .001) and sustained ROSC (11% vs. 25%; P < .001). The case fatality rate was 90% in the COVID-19 period vs. 75% a year earlier.

“The tragedy of the COVID-19 pandemic is not just the number of patients infected, but the large increase in OHCAs and deaths,” Dr. Prezant and colleagues said.

Identifying patients with the greatest risk for OHCA and death during the COVID-19 pandemic “should allow for early, targeted interventions in the outpatient setting that could lead to reductions in out-of-hospital deaths,” they noted.

“Vulnerable patient populations need outreach, telephonic medicine, televideo medicine, home visits, not just temperature monitoring but home O2 saturation monitoring,” Dr. Prezant said in an interview. “Barriers need to be removed, not just for this pandemic but for the future – no matter what the trigger is.”
 

 

 

Unsung heroes

In an Editor’s Note in JAMA Cardiology, Robert O. Bonow, MD, Northwestern University, Chicago, and colleagues said the American people owe a debt of gratitude to first responders for their “heroic work” triaging, resuscitating, and transporting thousands of people affected by COVID-19. 

Dr. Robert O. Bonow

“Although the typically bustling NYC streets remained eerily deserted, the characteristic cacophony of sounds of the ‘City that Never Sleeps’ was replaced by sirens wailing all hours of the night,” they wrote.

First responders to OHCAs in the COVID-19 era place themselves at extremely high risk, in some cases without optimal personal protective equipment, they pointed out. “Sadly,” many first responders have fallen ill to COVID-19 infection, they added.

As of June 1, 29 EMS workers and volunteers across the United States had died of COVID-19.

They are James Villecco, Gregory Hodge, Tony Thomas, Mike Field, John Redd, Idris Bey, Richard Seaberry, and Sal Mancuso of New York; Israel Tolentino, Reuven Maroth, Liana Sá, Kevin Leiva, Frank Molinari, Robert Weber, Robert Tarrant, Solomon Donald, Scott Geiger, John Farrarella, John Careccia, Bill Nauta, and David Pinto of New Jersey; Kevin Bundy, Robert Zerman, and Jeremy Emerich of Pennsylvania; Paul Cary of Colorado; Paul Novicki of Michigan; David Martin of Mississippi; Billy Birmingham of Missouri; and John “JP” Granger of South Carolina.

“We offer their families, friends, and colleagues our sincerest condolences and honor their memory with our highest respect and gratitude,” Dr. Bonow and colleagues wrote.

ACIP approves flu vaccine recommendations for 2020-2021

Article Type
Changed
Tue, 02/07/2023 - 16:49

 

A pair of new vaccines for adults aged 65 years and older will be available for the 2020-2021 flu season – Fluzone high-dose quadrivalent, which replaces the trivalent Fluzone high-dose and Fluad quadrivalent (Seqirus), according to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices.

At a virtual meeting on June 24, the committee voted unanimously to approve the vaccine recommendations for annual influenza immunization of all individuals aged 6 months and older. They also voted to accept some guidance and language changes to the recommendations.

The past flu season was unique in its overlap with the emergence of the COVID-19 coronavirus, which likely contributed to a third peak in reported cases of influenza-like illness at approximately week 14 of last season, said Lisa Grohskopf, MD, of the CDC’s influenza division, who presented data on last year’s activity and the updates for next season.

The CDC estimates that 39,000,000-56,000,000 flu illnesses occurred in the United States from Oct. 1, 2019, to April 4, 2020, said Dr. Grohskopf. Estimates also suggest as many as 740,000 hospitalizations and 62,000 deaths related to the seasonal flu.

Preliminary results of vaccine effectiveness showed 39% overall for the 2019-2020 season, with more substantial protection against influenza B and lower protection against A/H1N1pmd09.

Vaccine safety data from the Vaccine Adverse Event Reporting System and Vaccine Safety Datalink showed no new safety concerns for any flu vaccine types used last year, Dr. Grohskopf noted.

Based on this information, three components (A/H1N1pdm09, A/H3N2, and B/Victoria) have been updated for the 2020-2021 vaccines, said Dr. Grohskopf. The egg-based influenza vaccines will include hemagglutinin derived from an A/Guangdong-Maonan/SWL1536/2019(H1N1)pdm09–like virus, an A/Hong Kong/2671/2019(H3N2)–like virus and a B/Washington/02/2019 (Victoria lineage)–like virus, and (for quadrivalent vaccines) a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

Nonegg vaccines will contain hemagglutinin derived from an A/Hawaii/70/2019 (H1N1)pdm09–like virus, an A/Hong Kong/45/2019 (H3N2)–like virus, a B/Washington/02/2019 (Victoria lineage)–like virus, and a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

New guidance for next year’s flu season includes a change to the language in the contraindications and precautions table to simply read “Contraindications,” with more details in the text explaining package insert contraindications and ACIP recommendations, Dr. Grohskopf said. In addition, updated guidance clarifies that live-attenuated influenza vaccine quadravalents (LAIV4) should not be used in patients with cochlear implants, active cerebrospinal fluid leaks, and anatomical or functional asplenia, based on ACIP’s review of the latest evidence and the availability of alternative vaccines.

ACIP also updated guidance on the use of antivirals and LAIV4. Based on half-lives, language was added indicating that clinicians should assume interference if antivirals are given within certain intervals of LAIV4, Dr. Grohskopf explained. “Newer antivirals peramivir and baloxavir have longer half-lives than oseltamivir and zanamivir, and insufficient data are available on the use of LAIV4 in the setting of antiviral use.”

The ACIP members had no financial conflicts to disclose.

Combined PH subtypes predicts poor survival in kidney disease

Article Type

Thu, 06/25/2020 - 15:25

 

A combined subtype of pulmonary hypertension was significantly associated with higher mortality in adults with chronic kidney disease, based on data from a retrospective study of 12,618 patients.

Pulmonary hypertension (PH) occurs in up to 41% of chronic kidney disease (CKD) patients, but most studies of PH in this population have not examined PH subtypes, wrote Daniel L. Edmonston, MD, of Duke University, Durham, N.C., and colleagues.

“Among patients with CKD with PH, the combined pre- and postcapillary PH subtype (elevated pulmonary capillary wedge pressure with increased pulmonary vascular resistance) may be a substantial contributor to the overall PH burden in CKD” because of factors including chronic volume overload, pulmonary vascular remodeling, inflammation, and comorbid lung disease, they wrote.

In a study published in the American Journal of Kidney Diseases, The researchers investigated subtypes of precapillary, postcapillary, and combination PH, and their associations with all-cause mortality for different levels of CKD severity. The study population included 12,618 adults aged 18 years and older with qualifying right-heart catheterizations. Of these, 4,772 had chronic kidney disease. The average age was 57 years in patients without CKD and 69 years in patients with CKD.

Overall, 73.4% of patients with CKD and 56.9% of patients without CKD had PH. For CKD patients, the most common PH subtypes were isolated postcapillary (39.0%) and combined pre- and postcapillary (38.3%).

Combined pre- and postcapillary PH was associated with higher mortality risk, compared with no PH in CKD patients, with adjusted hazard ratios of 1.89, 1.87, 2.13, and 1.63 for glomerular filtration rate categories G3a, G3b, G4, and G5/G5D, respectively.

For patients without CKD, precapillary PH was the most common subtype (35.9%) and was associated with the highest mortality risk, compared with no PH (HR, 2.27).

Relationships between mortality and specific PH features of mean pulmonary artery pressure, pulmonary capillary wedge pressure, and right atrial pressure were similar for patients with and without CKD.

The study findings were limited by several factors including the observational design, potential lack of generalizability because of the use of data from a single center, and lack of data on vascular access for hemodialysis, and exclusion of patients with heart or lung transplants, the researchers noted.

However, the results suggest that “processes that increase pulmonary vascular resistance and/ or remodeling represent a prominent mechanism and potential therapeutic target for patients with CKD that is complicated by PH,” they said.

Patients with CKD and combined pre- and postcapillary PH are at increased risk for mortality and “recognition of this large combined pre- and postcapillary PH cohort in CKD may present new therapeutic options,” they concluded.

The study was supported by the National Institutes of Health and the American Society of Nephrology. The researchers had no financial conflicts to disclose.

A combined subtype of pulmonary hypertension was significantly associated with higher mortality in adults with chronic kidney disease, based on data from a retrospective study of 12,618 patients.

Pulmonary hypertension (PH) occurs in up to 41% of chronic kidney disease (CKD) patients, but most studies of PH in this population have not examined PH subtypes, wrote Daniel L. Edmonston, MD, of Duke University, Durham, N.C., and colleagues.

“Among patients with CKD with PH, the combined pre- and postcapillary PH subtype (elevated pulmonary capillary wedge pressure with increased pulmonary vascular resistance) may be a substantial contributor to the overall PH burden in CKD” because of factors including chronic volume overload, pulmonary vascular remodeling, inflammation, and comorbid lung disease, they wrote.

In a study published in the American Journal of Kidney Diseases, The researchers investigated subtypes of precapillary, postcapillary, and combination PH, and their associations with all-cause mortality for different levels of CKD severity. The study population included 12,618 adults aged 18 years and older with qualifying right-heart catheterizations. Of these, 4,772 had chronic kidney disease. The average age was 57 years in patients without CKD and 69 years in patients with CKD.

Overall, 73.4% of patients with CKD and 56.9% of patients without CKD had PH. For CKD patients, the most common PH subtypes were isolated postcapillary (39.0%) and combined pre- and postcapillary (38.3%).

Combined pre- and postcapillary PH was associated with higher mortality risk, compared with no PH in CKD patients, with adjusted hazard ratios of 1.89, 1.87, 2.13, and 1.63 for glomerular filtration rate categories G3a, G3b, G4, and G5/G5D, respectively.
