The Centers for Disease Control and Prevention acknowledged Oct. 5 in updated guidance that COVID-19 can sometimes be spread through the air, especially in enclosed spaces with poor ventilation, when people are more than 6 feet apart.

The information reiterates, however, that “COVID-19 is thought to spread mainly through close contact from person to person, including between people who are physically near each other (within about 6 feet). People who are infected but do not show symptoms can also spread the virus to others.”

In a statement to the media, the CDC said, “Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19–positive person left an area. In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. Such environments and activities may contribute to the buildup of virus-carrying particles.”

“This is HUGE and been long delayed. But glad it’s now CDC official,” tweeted Eric Feigl-Ding, MD, an epidemiologist and health economist at Harvard University, Boston on Oct. 5.

The CDC announcement follows an abrupt flip-flop on information last month surrounding the aerosol spread of the virus.
 

Information deleted from website last month

On September 18, the CDC had added to its existing guidance that the virus is spread “through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection.”

The CDC then deleted that guidance on Sept. 21, saying it was a draft update released in error.

A key element of the now-deleted guidance said, “this is thought to be the main way the virus spreads.”

The information updated today reverses the now-deleted guidance and says aerosol transmission is not the main way the virus spreads.

It states that people who are within 6 feet of a person with COVID-19 or have direct contact with that person have the greatest risk of infection.

The CDC reiterated in the statement to the media today, “People can protect themselves from the virus that causes COVID-19 by staying at least 6 feet away from others, wearing a mask that covers their nose and mouth, washing their hands frequently, cleaning touched surfaces often, and staying home when sick.”

Among the journals that have published evidence on aerosol spread is Clinical Infectious Diseases, which, on July 6, published the paper, “It Is Time to Address Airborne Transmission of Coronavirus Disease 2019,” which was supported by 239 scientists.

The authors wrote, “there is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale).”

Aerosols and airborne transmission “are the only way to explain super-spreader events we are seeing,” said Kimberly Prather, PhD, an atmospheric chemist at the University of California at San Diego, in an interview Oct. 5 with the Washington Post.

Dr. Prather added that, once aerosolization is acknowledged, this becomes a “fixable” problem through proper ventilation.

“Wear masks at all times indoors when others are present,” Dr. Prather said. But when inside, she said, there’s no such thing as a completely safe social distance.

Substance use disorders (SUD), particularly opioid addiction and smoking, are tied to an increased risk for COVID-19 and serious adverse outcomes including hospitalization and death, new research suggests.

A study funded by the National Institutes of Health assessed electronic health records of more than 73 million patients in the United States. Although only 10.3% of the participants had an SUD, “they represented 15.6% of the COVID-19 cases,” the investigators reported.

In addition, those with a recent diagnosis of SUD were eight times more likely to develop COVID-19 versus those without such a diagnosis. For specific SUDs, the greatest risk was for those with an opioid addiction followed by those who were addicted to cigarettes.

Is nicotine protective?

Dr. Volkow, her fellow senior author Rong Xu, PhD, Case Western Reserve University, Cleveland, and their team conducted the study because data released before the pandemic showed a significant increase in opioid overdose in 2019. “We were in an opioid crisis where we again saw an increase in mortality associated with overdose – and then COVID comes along. So the question was how are people who are already struggling faring? And if they were getting infected [with the coronavirus], what happened to them?”

Patients with SUDs have multiple medical comorbidities that are known risk factors for COVID-19, Dr. Volkow noted.

However, the only specific SUD that has been previously studied in this context is tobacco use disorder, she said. A report from Chinese investigators released early in the pandemic showed that smokers were more likely to be infected by coronavirus and more likely to die from COVID-19.

Interestingly, a cross-sectional study published in April suggested that smoking may be protective against COVID, and Dr. Volkow noted that a clinical study currently being conducted in France is assessing whether wearing a nicotine patch has the potential to prevent the virus.

“That’s very different from looking at a chronic smoker,” she pointed out. “It’s a potential that nicotine as a chemical [could be] a preventive measure as opposed to saying smoking will prevent you from getting COVID.”

Patients with SUDs, said Dr. Volkow, “are likely to be at greater risk because of the effects of drugs in the metabolic system and the interfering with oxygenation in the pulmonary vessels.”

The retrospective case-control study included EHR data from 73.1 million patients. In the study population, 54% were women, 55% were White, 10% Black, 2% Asian, 1% Hispanic/Latino, and the others were classified as other or unknown.

EHRs were collected through June 15 at 360 hospitals in all 50 states and were deidentified to ensure privacy. SUDs included alcohol, tobacco, cannabis, opioid, and cocaine.
 

Racial disparities

Results showed that about 7.5 million participants had a previous SUD diagnosis; of these, 722,370 had been diagnosed within the past year.

Tobacco use disorder was the most common diagnosis (n = 6,414,580), followed by alcohol (1,264,990), cannabis (490,420), opioid (471,520), and cocaine (222,680).

In addition, 12,030 (60% women) were diagnosed with COVID-19 and 1,880 had both COVID-19 and an SUD.

Adjusted analyses revealed that those who had a recent diagnosis of SUD were at a significantly greater increased risk for COVID-19 than individuals without an SUD (adjusted odds ratio, 8.7; 95% confidence interval, 8.4-9.0; P < 10^–30).

This increased risk was greatest in participants with opioid use disorder (aOR, 10.2; 95% CI, 9.1-11.5; P < 10^–30), followed by those with tobacco use disorder (aOR, 8.2; 95% CI, 7.9 - 8.5; P < 10–30).

Alcohol, cocaine, and cannabis had aORs of 7.7, 6.5, and 5.3, respectively. The aOR for lifetime SUD and COVID-19 was 1.5.

Among all patients with COVID-19, hospitalization rates were significantly greater in those with an SUD (43.8%) versus those without (30.1%), as were death rates at 9.6% versus 6.6%, respectively.

Race was a significant risk factor. Black patients with a recent SUD diagnosis were twice as likely as White patients to develop COVID-19 (aOR, 2.2; P < 10^–30), and those specifically with opioid use disorder were four times more likely to develop the disease (aOR, 4.2  P < 10^–25).

Black patients with both COVID-19 and lifetime SUD also had greater hospitalization and death rates versus their White peers (50.7% vs. 35.2% and 13% vs. 8.6%, respectively).

“This surprised me,” Dr. Volkow noted. “You can see the emergence of the racial disparities even under these conditions of really negative outcomes.”
 

Vulnerable populations

Cancer; obesity; HIV; diabetes; cardiovascular disease; and chronic kidney, liver, and lung diseases, which are all risk factors for COVID-19, were more prevalent in the group of patients with a recent SUD diagnosis versus those without.

In addition, asthma, type 2 diabetes, hypertension, obesity, and chronic kidney disease were more prevalent in the Black patents with a recent SUD than in the White patients.

Overall, the findings “identify individuals with SUD as a vulnerable population, especially African Americans with SUDs, who are at significantly increased risk for COVID-19 and its adverse outcomes,” the investigators wrote.

The results also highlight “the need to screen and treat individuals with SUD as part of the strategy to control the pandemic while ensuring no disparities in access to healthcare support,” they added.

Dr. Volkow noted that “marginalization” often occurs for individuals with addiction, making it more difficult for them to access health care services.

“It is incumbent upon clinicians to meet the unique challenges of caring for this vulnerable population, just as they would any other high-risk group,” she said.

“Patients should not just be treated for COVID, but should also be provided with treatment for their substance use disorder,” Dr. Volkow added.
 

‘Pretty convincing’

Andrew J. Saxon, MD, professor in the department of psychiatry and behavioral sciences at the University of Washington, Seattle, called the findings interesting.

“I found it pretty convincing that people who have substance use disorders are probably at higher risk for getting COVID-19 infection and more complications once they are infected,” he said.

Dr. Saxon, who was not involved with the research, is also director of the Center of Excellence in Substance Addiction Treatment and Education and is a member of the American Psychiatric Association’s Council on Addiction Psychiatry.

He noted that an important point from the study was not just about a patient having an SUD being at increased risk for COVID-19 “and a more severe disease trajectory.” Other factors associated with having an SUD, such as increased comorbidities, also likely play a part.

Dr. Saxon agreed that the ongoing opioid epidemic combined with the pandemic led to a “perfect storm” of problems.

“We were making slow but some progress getting more people the medications they need [to treat opioid use disorder], but the pandemic coming along disrupted those efforts. A lot of health care entities had to shut down for a while, seeing patients only remotely,” which led to barriers as many clinicians needed to learn how to proceed using telehealth options, said Dr. Saxon.
 

Universal screening?

Asked whether physicians should screen all patients for SUDs, Dr. Saxon said it’s a complicated question.

“Screening for tobacco and alcohol has a really good evidence base and practices should be doing that. The stigma is there but it’s a lot less than with illegal substances,” he said.

Screening for illegal substances or misuse of prescription substances may not be a good idea in health care settings “when it’s something they can’t do anything about. If you’re going to screen, you would have to have either referral processes in place or treatment available in your facility,” Dr. Saxon said.

Opioid use disorder is “especially amenable to treatment in a primary care or health care setting with prescribers,” he noted.

However, stimulant or cannabis use disorders “require fairly intensive behavioral interventions that are not easy to deliver in many health care settings. And we don›t have the workforce trained up to provide those treatments as widely as they should be,” said Dr. Saxon.

“Unless there’s some way to treat the issue, what’s the point of screening for it? That just creates frustration for patients and clinicians, as well,” he said. “It’s something we’re moving toward but we’re not quite there yet.”

The report authors and Dr. Saxon have disclosed no relevant financial relationships.

A lot of health care entities had to shut down for a while, seeing patients only remotely,” which led to barriers as many clinicians needed to learn how to proceed using telehealth options, said Dr. Saxon.
 

Universal screening?

Asked whether physicians should screen all patients for SUDs, Dr. Saxon said it’s a complicated question.

“Screening for tobacco and alcohol has a really good evidence base and practices should be doing that. The stigma is there but it’s a lot less than with illegal substances,” he said.

Screening for illegal substances or misuse of prescription substances may not be a good idea in health care settings “when it’s something they can’t do anything about. If you’re going to screen, you would have to have either referral processes in place or treatment available in your facility,” Dr. Saxon said.

Opioid use disorder is “especially amenable to treatment in a primary care or health care setting with prescribers,” he noted.

However, stimulant or cannabis use disorders “require fairly intensive behavioral interventions that are not easy to deliver in many health care settings. And we don›t have the workforce trained up to provide those treatments as widely as they should be,” said Dr. Saxon.

“Unless there’s some way to treat the issue, what’s the point of screening for it? That just creates frustration for patients and clinicians, as well,” he said. “It’s something we’re moving toward but we’re not quite there yet.”

The report authors and Dr. Saxon have disclosed no relevant financial relationships.

Black children and children living in urban areas are less likely to have opioid-related poisoning or withdrawal but more likely to experience abuse or dependence, compared with their White or rural/suburban counterparts, according to a study of 3.2 million Medicaid-enrolled children in North Carolina.

Analysis of the almost 138,000 prescription fills also showed that Black and urban children in North Carolina were less likely to fill a opioid prescription, suggesting a need “for future studies to explore racial and geographic opioid-related inequities in children,” Kelby W. Brown, MA, and associates at Duke University, Durham, N.C., said Oct. 5 in Health Affairs.

In 2016-2018, the prevalence of opioid-related adverse events, such as poisoning or withdrawal, was 24.0 per 100,000 children among Blacks aged 1-17 years, compared with 27.5 per 100,000 for whites. For other opioid-related harms such as abuse or dependence, the order was reversed: 60.2 for Blacks and 51.7 for Whites, the investigators reported. Children of all other races were lowest in both measures.

Geography also appears to play a part. The children in urban areas had the lowest rate of adverse events – 23.2 per 100,000 vs. 26.2 (suburban) and 26.7 (rural) – and the highest rate of other opioid-related harms – 58.1 vs. 49.0 (suburban) and 38.7 (rural), the Medicaid claims data showed.

Analysis of prescription fills revealed that black children aged 1-17 years had a significantly lower rate (2.7%) than Whites (3.1%) or those of other races (3.0%) and that urban children were significantly less likely to fill a prescription (2.7%) for opioids than the other two groups (suburban, 3.1%; rural, 3.4%), Mr. Brown and associates said.

The prescription data also showed that 48.4% of children aged 6-17 years who had an adverse event had filled a prescription for an opioid in the previous 6 months, compared with just 9.4% of those with other opioid-related harms. The median length of time since the last fill? Three days for children with an adverse event and 67 days for those with other harms, they said.

And those prescriptions, it turns out, were not coming just from the physicians of North Carolina. Physicians, with 35.5% of the prescription load, were the main source, but 33.3% of opioid fills in 2016-2018 came from dentists, and another 17.7% were written by advanced practice providers. Among physicians, the leading opioid-prescribing specialists were surgeons, with 17.3% of the total, the investigators reported.

“The distinct and separate groups of clinicians who prescribe opioids to children suggest the need for pediatric opioid prescribing guidelines, particularly for postprocedural pain,” Mr. Brown and associates wrote.

Spain and China used very different public health responses to the COVID-19 crisis, and that has had significant consequences in terms of the mental health as well as physical health of the two countries’ citizens, Roger Ho, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.
 

Dr. Ho, a psychiatrist at the National University of Singapore, presented a first-of-its-kind cross-cultural comparative study of the impact of the COVID-19 pandemic in two epicenters on opposite sides of the world. A total of 1,539 participants drawn from the general populations in the two countries completed the online National University of Singapore COVID-19 Questionnaire. The survey was conducted in late February/early March in China and in mid-April in Spain, times of intense disease activity in the countries.

The questionnaire assesses knowledge and concerns about COVID, precautionary measures taken in the last 14 days, contact history, and physical symptoms related to COVID in the last 14 days. The pandemic’s psychological impact was evaluated using the Impact of Event Scale–Revised (IES-R). Participants also completed the Depression, Anxiety, and Stress-21 Scale (DASS-21).

Of note, the pandemic has taken a vastly greater physical toll in Spain than China. As of May 5, there were 83,000 confirmed cases of COVID-19 in China, with a population of 1.39 billion, compared with 248,000 in Spain, with a population of 46.9 million. The Spanish case rate of 5,500 per 1 million population was 100 times greater than China’s; the Spanish mortality rate of 585 per million was 185-fold greater.
 

Mental health findings

Spaniards experienced significantly higher levels of stress and depression as reflected in DASS-21 subscale scores of 14.22 and 8.65, respectively, compared with 7.86 and 6.38, in Chinese respondents. Spanish subjects also reported greater anxiety levels than the Chinese on the DASS-21 anxiety subscale, although not to a statistically significant extent. Yet, counterintuitively, given the DASS-21 results, the pandemic had a greater adverse psychological impact on the Chinese subjects as reflected in their significantly higher average IES-D score of 30.76 versus 27.64 in Spain. Dr. Ho offered a hypothesis as to why: The survey documented that many Chinese respondents felt socially stigmatized, and that their nation had been discriminated against by the rest of the world because the pandemic started in China.

Satisfaction with the public health response

Spanish respondents reported less confidence in their COVID-related medical services.

“This could be due to the rising number of infected health care workers in Spain. In contrast, the Chinese had more confidence in their medical services, probably because the government quickly deployed medical personnel and treated COVID-19 patients at rapidly built hospitals,” according to Dr. Ho.

Spain and other European countries shared four shortcomings in their pandemic response, he continued: lack of personal protective equipment for health care workers, delay in developing response strategies, a shortage of hospital beds, and inability to protect vulnerable elderly individuals from infection in nursing homes.

Experiencing cough, shortness of breath, myalgia, or other physical symptoms potentially associated with COVID-19 within the past 14 days was associated with worse depression, anxiety, and stress scores in both China and Spain. This underscores from a mental health standpoint the importance of rapid and accurate testing for the infection, Dr. Ho said.

Significantly more Spanish respondents felt there was too much unnecessary worry about COVID-19, suggesting a need for better health education regarding the pandemic.
 

Use of face masks

Consistent use of face masks regardless of the presence or absence of symptoms was far more common in the Chinese epicenter, where, unlike in Spain, this precautionary measure was associated with significantly lower IES-R and DASS-21 scores.

“One of the important findings in our study is that wearing a face mask seems to protect the mental health in China, but for the Spanish, wearing a face mask was associated with higher IES-R scores,” Dr. Ho said. “We understand that it is difficult for Europeans to accept the need to use masks for healthy people because mask-wearing suggests vulnerability to sickness and concealment of identity. The Chinese have a collective culture. They believe they should wear a face mask to protect their health and that of other people.”

Dr. Ho reported no financial conflicts regarding his study, conducted with coinvestigators at Huaibei (China) Normal University and Complutense University of Madrid.

President Donald Trump’s COVID-19 diagnosis is raising fresh questions about the White House’s strategy for testing and containing the virus for a president whose cavalier attitude about the coronavirus has persisted since it landed on American shores.

The president has said others are tested before getting close to him, appearing to hold it as an iron shield of safety. He has largely eschewed mask-wearing and social distancing in meetings, travel and public events, while holding rallies for thousands of often maskless supporters.

The Trump administration has increasingly pinned its coronavirus testing strategy for the nation on antigen tests, which do not need a traditional lab for processing and quickly return results to patients. But the results are less accurate than those of the slower PCR tests. 

An early antigen test used by the White House was woefully inaccurate. But the new antigen test the White House is using has not been independently evaluated for accuracy and reliability. Moreover, this is the kit the Trump administration is pushing out to thousands of nursing homes to test residents and staff.

Testing “isn’t a ‘get out of jail free card,’” said Dr. Alan Wells, medical director of clinical labs at the University of Pittsburgh Medical Center and creator of its test for the novel coronavirus. In general, antigen tests can miss up to half the cases that are detected by polymerase chain reaction tests, depending on the population of patients tested, he said.

The White House said the president’s diagnosis was confirmed with a PCR test but declined to say which test delivered his initial result. The White House has been using a new antigen test from Abbott Laboratories to screen its staff for COVID-19, according to two administration officials. 

The test, known as BinaxNOW, received an emergency use authorization from the Food and Drug Administration in August. It produces results in 15 minutes. Yet little is independently known about how effective it is. According to the company, the test is 97% accurate in detecting positives and 98.5% accurate in identifying those without disease. Abbott’s stated performance of its antigen test was based on examining people within 7 days of COVID symptoms appearing.

The president and first lady have both had symptoms, according to White House chief of staff Mark Meadows and the first lady’s Twitter account. The president was admitted to Walter Reed National Military Medical Center on Friday evening “out of an abundance of caution,” White House press secretary Kayleigh McEnany said in a statement.

Vice President Mike Pence is also tested daily for the virus and tested negative, spokesperson Devin O’Malley said Friday, but he did not respond to a follow-up question about which test was used.

Trump heavily promoted another Abbott rapid testing device, the ID NOW, earlier this year. But that test relies on different technology than the newer Abbott antigen test.

“I have not seen any independent evaluation of the Binax assay in the literature or in the blogs,” Wells said. “It is an unknown.”

The Department of Health and Human Services announced in August that it had signed a $760 million contract with Abbott for 150 million BinaxNOW antigen tests, which are now being distributed to nursing homes and historically black colleges and universities, as well as to governors to help inform decisions about opening and closing schools. The Big Ten football conference has also pinned playing hopes on the deployment of antigen tests following Trump’s political pressure.

However, even senior federal officials concede that a test alone isn’t likely to stop the spread of a virus that has sickened more than 7 million Americans.

“Testing does not substitute for avoiding crowded indoor spaces, washing hands, or wearing a mask when you can’t physically distance; further, a negative test today does not mean that you won’t be positive tomorrow,” Adm. Brett Giroir, the senior HHS official helming the administration’s testing effort, said in a statement at the time.

Trump could be part of a “super-spreading event,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Given the timing of Trump’s positive test — which he announced on Twitter early Friday – his infection “likely happened 5 or more days ago,” Osterholm said. “If so, then he was widely infectious as early as Tuesday,” the day of the first presidential debate in Cleveland.

At least seven people who attended a Rose Garden announcement last Saturday, when Trump announced his nomination of Judge Amy Coney Barrett to the Supreme Court, have since tested positive for the coronavirus. They include Trump’s former adviser Kellyanne Conway, Republican Sens. Mike Lee and Thom Tillis, and the president of the University of Notre Dame, the Rev. John Jenkins.

“Having that many infected people there all at one time, we’re still going to see transmission coming off that event for a couple days,” Osterholm said.

Osterholm notes that about 20% of infected people lead to 80% of COVID-19 cases, because “super spreaders” can infect so many people at once.

He notes that participants and audience members at Tuesday’s debate were separated by at least 6 feet. But 6 feet isn’t always enough to prevent infection, he said.

While many COVID-19 infections appear to be spread by respiratory droplets, which usually fall to the ground within 6 feet, people who are singing or speaking loudly can project virus much further. Evidence also suggests that the novel coronavirus can spread through aerosols, floating in the air like a speck of dust.

“I wonder how much virus was floating in that room that night,” Osterholm said.

Other experts say it’s too soon to say whether Trump was infected in a super-spreader event. “The president and his wife have had many exposures to many people in enclosed venues without protection,” so they could have been infected at any number of places, said Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine. 

Although Democratic presidential candidate and former Vice President Joe Biden tested negative for the virus with a PCR test Friday, experts note that false-negative results are common in the first few days after infection. Test results over the next several days will yield more useful information.

It can take more than a week for the virus to reproduce enough to be detected, Wells said: “You are probably not detectable for 3, 5, 7, even 10 days after you’re exposed.”

In Minnesota, where Trump held an outdoor campaign rally in Duluth with hundreds of attendees Wednesday, health officials warned that a 14-day quarantine is necessary, regardless of test results.

“Anyone who was a direct contact of President Trump or known COVID-19 cases needs to quarantine and should get tested,” the Minnesota Department of Health said.

Ongoing lapses in test result reporting could hamper efforts to track and isolate sick people. As of Sept. 10, 21 states and the District of Columbia were not reporting all antigen test results, according to a KHN investigation, a lapse in reporting that officials say leaves them blind to disease spread. Since then, public health departments in Arizona, North Carolina and South Dakota all have announced plans to add antigen testing to their case reporting.

Requests for comment to the D.C. Department of Health were referred to Mayor Muriel Bowser’s office, which did not respond. District health officials told KHN in early September that the White House does not report antigen test results to them – a potential violation of federal law under the CARES Act, which says any institution performing tests to diagnose COVID-19 must report all results to local or state public health departments.

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said it’s not surprising that Trump tested positive, given that so many of his close associates – including his national security adviser and Secret Service officers – have also been infected by the virus.

“When you look at the number of social contacts and travel schedules, it’s not surprising,” Adalja said.

Trump heavily promoted another Abbott rapid testing device, the ID NOW, earlier this year. But that test relies on different technology than the newer Abbott antigen test.

“I have not seen any independent evaluation of the Binax assay in the literature or in the blogs,” Wells said. “It is an unknown.”

The Department of Health and Human Services announced in August that it had signed a $760 million contract with Abbott for 150 million BinaxNOW antigen tests, which are now being distributed to nursing homes and historically black colleges and universities, as well as to governors to help inform decisions about opening and closing schools. The Big Ten football conference has also pinned playing hopes on the deployment of antigen tests following Trump’s political pressure.

However, even senior federal officials concede that a test alone isn’t likely to stop the spread of a virus that has sickened more than 7 million Americans.

“Testing does not substitute for avoiding crowded indoor spaces, washing hands, or wearing a mask when you can’t physically distance; further, a negative test today does not mean that you won’t be positive tomorrow,” Adm. Brett Giroir, the senior HHS official helming the administration’s testing effort, said in a statement at the time.

Trump could be part of a “super-spreading event,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Given the timing of Trump’s positive test — which he announced on Twitter early Friday – his infection “likely happened 5 or more days ago,” Osterholm said. “If so, then he was widely infectious as early as Tuesday,” the day of the first presidential debate in Cleveland.

At least seven people who attended a Rose Garden announcement last Saturday, when Trump announced his nomination of Judge Amy Coney Barrett to the Supreme Court, have since tested positive for the coronavirus. They include Trump’s former adviser Kellyanne Conway, Republican Sens. Mike Lee and Thom Tillis, and the president of the University of Notre Dame, the Rev. John Jenkins.

“Having that many infected people there all at one time, we’re still going to see transmission coming off that event for a couple days,” Osterholm said.

Osterholm notes that about 20% of infected people lead to 80% of COVID-19 cases, because “super spreaders” can infect so many people at once.

He notes that participants and audience members at Tuesday’s debate were separated by at least 6 feet. But 6 feet isn’t always enough to prevent infection, he said.

While many COVID-19 infections appear to be spread by respiratory droplets, which usually fall to the ground within 6 feet, people who are singing or speaking loudly can project virus much further. Evidence also suggests that the novel coronavirus can spread through aerosols, floating in the air like a speck of dust.

“I wonder how much virus was floating in that room that night,” Osterholm said.

Other experts say it’s too soon to say whether Trump was infected in a super-spreader event. “The president and his wife have had many exposures to many people in enclosed venues without protection,” so they could have been infected at any number of places, said Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine. 

Although Democratic presidential candidate and former Vice President Joe Biden tested negative for the virus with a PCR test Friday, experts note that false-negative results are common in the first few days after infection. Test results over the next several days will yield more useful information.

It can take more than a week for the virus to reproduce enough to be detected, Wells said: “You are probably not detectable for 3, 5, 7, even 10 days after you’re exposed.”

In Minnesota, where Trump held an outdoor campaign rally in Duluth with hundreds of attendees Wednesday, health officials warned that a 14-day quarantine is necessary, regardless of test results.

“Anyone who was a direct contact of President Trump or known COVID-19 cases needs to quarantine and should get tested,” the Minnesota Department of Health said.

Ongoing lapses in test result reporting could hamper efforts to track and isolate sick people. As of Sept. 10, 21 states and the District of Columbia were not reporting all antigen test results, according to a KHN investigation, a lapse in reporting that officials say leaves them blind to disease spread. Since then, public health departments in Arizona, North Carolina and South Dakota all have announced plans to add antigen testing to their case reporting.

Requests for comment to the D.C. Department of Health were referred to Mayor Muriel Bowser’s office, which did not respond. District health officials told KHN in early September that the White House does not report antigen test results to them – a potential violation of federal law under the CARES Act, which says any institution performing tests to diagnose COVID-19 must report all results to local or state public health departments.

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said it’s not surprising that Trump tested positive, given that so many of his close associates – including his national security adviser and Secret Service officers – have also been infected by the virus.

“When you look at the number of social contacts and travel schedules, it’s not surprising,” Adalja said.

President Donald Trump’s COVID-19 diagnosis is raising fresh questions about the White House’s strategy for testing and containing the virus for a president whose cavalier attitude about the coronavirus has persisted since it landed on American shores.

The president has said others are tested before getting close to him, appearing to hold it as an iron shield of safety. He has largely eschewed mask-wearing and social distancing in meetings, travel and public events, while holding rallies for thousands of often maskless supporters.

The Trump administration has increasingly pinned its coronavirus testing strategy for the nation on antigen tests, which do not need a traditional lab for processing and quickly return results to patients. But the results are less accurate than those of the slower PCR tests. 

An early antigen test used by the White House was woefully inaccurate. But the new antigen test the White House is using has not been independently evaluated for accuracy and reliability. Moreover, this is the kit the Trump administration is pushing out to thousands of nursing homes to test residents and staff.

Testing “isn’t a ‘get out of jail free card,’” said Dr. Alan Wells, medical director of clinical labs at the University of Pittsburgh Medical Center and creator of its test for the novel coronavirus. In general, antigen tests can miss up to half the cases that are detected by polymerase chain reaction tests, depending on the population of patients tested, he said.

The White House said the president’s diagnosis was confirmed with a PCR test but declined to say which test delivered his initial result. The White House has been using a new antigen test from Abbott Laboratories to screen its staff for COVID-19, according to two administration officials. 

The test, known as BinaxNOW, received an emergency use authorization from the Food and Drug Administration in August. It produces results in 15 minutes. Yet little is independently known about how effective it is. According to the company, the test is 97% accurate in detecting positives and 98.5% accurate in identifying those without disease. Abbott’s stated performance of its antigen test was based on examining people within 7 days of COVID symptoms appearing.

The president and first lady have both had symptoms, according to White House chief of staff Mark Meadows and the first lady’s Twitter account. The president was admitted to Walter Reed National Military Medical Center on Friday evening “out of an abundance of caution,” White House press secretary Kayleigh McEnany said in a statement.

Vice President Mike Pence is also tested daily for the virus and tested negative, spokesperson Devin O’Malley said Friday, but he did not respond to a follow-up question about which test was used.

Current and former users of e-cigarettes are more likely to report sleep deprivation, compared with those who have never used e-cigarettes, according to the first study to evaluate the association in a large, nationally representative population of young adults.

“The e-cigarette use and sleep deprivation association seems to have a dose-response nature as the point estimate of the association increased with increased exposure to e-cigarette,” Sina Kianersi, DVM, and associates at Indiana University, Bloomington, said in Addictive Behaviors.

Sleep deprivation was 49% more prevalent among everyday users of e-cigarettes, compared with nonusers. Prevalence ratios for former users (1.31) and occasional users (1.25) also showed significantly higher sleep deprivation, compared with nonusers, they reported based on a bivariate analysis of data from young adults aged 18-24 years who participated in the 2017 and 2018 Behavioral Risk Factor Surveillance System surveys.

After adjustment for multiple confounders, young adults who currently used e-cigarettes every day were 42% more likely to report sleep deprivation than those who never used e-cigarettes, a difference that was statistically significant. The prevalence of sleep deprivation among those who used e-cigarettes on some days was not significantly higher (prevalence ratio, 1.08), but the ratio between former users and never users was a significant 1.17, the investigators said.

“The nicotine in the inhaled e-cigarette aerosols may have negative effects on sleep architecture and disturb the neurotransmitters that regulate sleep cycle,” they suggested, and since higher doses of nicotine produce greater reductions in sleep duration, “those who use e-cigarette on a daily basis might consume higher doses of nicotine, compared to some days, former, and never users, and therefore get fewer hours of sleep.”

Nicotine withdrawal, on the other hand, has been found to increase sleep duration in a dose-dependent manner, which “could explain the smaller [prevalence ratios] observed for the association between e-cigarette use and sleep deprivation among former and some days e-cigarette users,” Dr. Kianersi and associates added.

The bivariate analysis involved 18,945 survey respondents, of whom 16,427 were included in the fully adjusted model using 12 confounding factors.

With high rates of fatty liver disease known to occur among people with type 2 diabetes, is it time to introduce routine liver screening into daily diabetes practice? The answer depends on whom you ask, and then there are still some important caveats.

Wavebreakmedia Ltd/ThinkStockPhotos.com

From the hepatologist’s perspective, there is no excuse not to consider liver surveillance now that noninvasive screening methods are available, suggested Michael Trauner, MD, of the Medical University of Vienna.

“From a practical standpoint, I think every type 2 diabetic over 50 years of age is at high risk,” and consequently should be screened at diagnosis, Dr. Trauner said during a debate at the virtual annual meeting of the European Association for the Study of Diabetes. “I would screen at diagnosis and then decide on recall depending on noninvasive fibrosis markers.”

“It’s a rising problem that we are facing these days,” observed Michael Roden, MD, chair and professor of internal medicine, endocrinology and metabolic diseases at Heinrich-Heine University in Düsseldorf, Germany, and who cochaired the session. Not only do people with type 2 diabetes have an increased risk for developing liver diseases, but also there’s a higher risk for those with fatty liver diseases developing type 2 diabetes.

A meta-analysis published in Gut in just last week illustrates just how big a problem this is – nonalcoholic fatty liver disease (NAFLD) “doubled the risk of type 2 diabetes,” said Dr Rosen, who is also the director of the division of endocrinology and diabetology at University Clinics Düsseldorf. That analysis was based on more than 500,000 people, almost 28,000 of whom had incident diabetes over a 5-year period.
 

Screening tools scarce

This makes liver screening in type 2 diabetes patients “a formidable challenge,” cautioned Gianluca Perseghin, MD, professor of endocrinology at the Monza (Italy) Polyclinic and the University of Milano-Bicocca in Milan.

“Hepatologists generally see only the most severe cases,” Dr. Perseghin said. Diabetologists and endocrinologists would be likely to see huge numbers of patients that could potentially be at risk for liver disease and following the recommendations set out in the joint European Association for the Study of the Liver/EASD/European Association for the Study of Obesity guidelines would result in a huge number of patients being identified and potentially needing referral, he argued.

“At this stage, we need to build friendly, reliable and cost-effective screening process to be applied in the health systems,” Dr. Perseghin suggested. He proposed that liver surveillance would need to be not only personalized on a patient level, but also at the infrastructure level. Measuring liver enzymes, for example, was going to be less accurate in picking up liver disease but blood tests were widely available, whereas imaging methods were not going to be something all diabetes clinics would have immediate access to.

“There are clearly a lot of provocative decisions still to be made,” acknowledged Philip Newsome, PhD, FRCPE, an honorary consultant hepatologist at the University of Birmingham (England) and who cochaired the debate.

“We need to demonstrate that looking for the presence of liver disease in this cohort changes their outcomes in a way that is cost effective,” Dr. Newsome, who is also the secretary general of EASL.

“Tests are evolving, but more importantly, treatments are evolving. So, the decision around cost effectiveness will clearly change,” he added.
 

NAFLD therapies unclar

“There are still a lot of questions,” Dr. Newsome said during a Novo-Nordisk–sponsored “Meet the Expert” session discussing EASL-EASD-EASO guidelines. “We don’t have any licensed therapies at the moment. But there’s been a huge amount of investment, looking at all sorts of different approaches.”

Dr. Newsome added: “We also don’t know how to monitor these patients. Most of the noninvasive are very useful for staging patients, but we don’t really understand how useful they are for monitoring changes in fibrosis.”

Diabetologist Hannele Yki-Järvinen, MD, PhD, of the University of Helsinki, gave her thoughts on the topic during the same session.

“We should add FIB-4 [Fibrosis-4 index] to the annual exam and ask the lab to calculate FIB-4 automatically,” Dr. Yki-Järvinen said. FIB-4is calculated using the patients age and the results of readily available blood tests that measure the AST/ALT ratio and the platelet count.

Dr. Trauner has received advisory fees and grant support from various companies with an interest in developing liver-directed therapies, and is also a coinventor of 24-norursodeoxycholic acid under development for cholestatic liver disease and potentially NAFLD. Dr. Perseghin has received honoraria and grant support from various pharmaceutical companies with an interest in diabetes care. Dr. Roden did not provide any disclosures. Dr. Newsome has received research grants from Boehringer Ingelheim and Novo Nordisk and acted as a consultant to many pharmaceutical companies. Dr. Yki-Järvinen disclosed receiving consultancy fees from Eli Lilly, MSD, and Novo Nordisk.

The DAPA-CKD trial results, which proved dapagliflozin’s efficacy for slowing chronic kidney disease progression in patients selected for signs of worsening renal function, also have important messages for cardiologists, especially heart failure physicians.

Those messages include findings that were “consistent” with the results of the earlier DAPA-HF trial, which tested the same sodium-glucose transporter 2 (SGLT2) inhibitor in patients selected for having heart failure with reduced ejection fraction (HFrEF). In addition, a specific action of dapagliflozin (Farxiga) on the patients in DAPA-CKD, which enrolled patients based on markers of chronic kidney disease (CKD), was prevention of first and recurrent heart failure hospitalizations, John J.V. McMurray, MD, said at the virtual annual scientific meeting of the Heart Failure Society of America, further highlighting the role that dapagliflozin has in reducing both heart failure and renal events.
 

What DAPA-CKD means for heart failure

The main findings from the DAPA-CKD trial, published in September in the New England Journal of Medicine, included as a secondary outcome the combined rate of death from cardiovascular causes or hospitalization for heart failure (HHF). Treatment with dapagliflozin linked with a significant 29% relative reduction in this endpoint, compared with placebo-treated patients. At the HFSA meeting, Dr. McMurray reported for the first time the specific HHF numbers, a prespecified secondary endpoint for the study.

Patients on dapagliflozin had 37 total HHF events (1.7%), including both first-time and subsequent hospitalizations, while patients in the placebo arm had a total of 71 HHF events (3.3%) during the study’s median 2.4 years of follow-up, an absolute reduction of 1.6% that translated into a relative risk reduction of 49%.

The HHF findings from DAPA-CKD importantly showed that SGLT2 inhibition in patients with signs of renal dysfunction “will not only slow progression of kidney disease but will also reduce the risk of developing heart failure, crucially in patients with or without type 2 diabetes,” explained Dr. McMurray in an interview. “Cardiologists often consult in the kidney wards and advise on management of patients with chronic kidney disease, even those without heart failure.”

The DAPA-CKD findings carry another important message for heart failure management regarding the minimum level of renal function a patient can have and still safely receive dapagliflozin or possibly another agent from the same SGLT2 inhibitor class. In DAPA-CKD, patients safely received dapagliflozin with an estimated glomerular filtration rate (eGFR) as low as 25 mL/min per 1.73 m²; 14% of enrolled patients had an eGFR of 25-29 mL/min per 1.73 m².

“Typically, about 40%-50% of patients with heart failure have chronic kidney disease,” which makes this safety finding important to clinicians who care for heart failure patients, but it’s also important for any patient who might be a candidate for dapagliflozin or another drug from its class. “We had no strong evidence before this trial that SGLT2 inhibition could reduce hard renal endpoints,” specifically need for chronic dialysis, renal transplant, or renal death, “in patients with or without diabetes,” Dr. McMurray said.
 

DAPA-CKD grows the pool of eligible heart failure patients

A further consequence of the DAPA-CKD findings is that when, as expected, regulatory bodies give dapagliflozin an indication for treating the types of CKD patients enrolled in the trial, it will functionally expand this treatment to an even larger swath of heart failure patients who currently don’t qualify for this treatment, specifically patients with CKD who also have heart failure with preserved ejection fraction (HFpEF). On Oct. 2, 2020, the Food and Drug Administration fast-tracked dapagliflozin for the CKD indication by granting it Breakthrough Therapy Designation based on the DAPA-CKD results.

Results first reported in 2019 from the DAPA-HF trial led to dapagliflozin receiving a labeled indication for treating HFrEF, the types of heart failure patients enrolled in the trial. Direct evidence on the efficacy of SGLT2 inhibitors for patients with HFpEF will not be available until results from a few trials now in progress become available during the next 12 months.

In the meantime, nearly half of patients with HFpEF also have CKD, noted Dr. McMurray, and another large portion of HFpEF patients have type 2 diabetes and hence qualify for SGLT2 inhibitor treatment that way. “Obviously, we would like to know specifically about heart failure outcomes in patients with HFpEF” on SGLT2 inhibitor treatment, he acknowledged. But the recent approval of dapagliflozin for patients with HFrEF and the likely indication coming soon for treating CKD means that the number of patients with heart failure who are not eligible for SGLT2 inhibitor treatment is dwindling down to some extent.
 

New DAPA-HF results show no drug, device interactions

In a separate session at the HFSA virtual meeting, Dr. McMurray and several collaborators on the DAPA-HF trial presented results from some new analyses. Dr. McMurray looked at the impact of dapagliflozin treatment on the primary endpoint when patients were stratified by the diuretic dosage they received at study entry. The results showed that “the benefits from dapagliflozin were irrespective of the use of background diuretic therapy or the diuretic dose,” he reported. Study findings also showed that roughly three-quarters of patients in the study had no change in their diuretic dosage during the course of the trial, that the fraction of patients who had an increase in their dosage was about the same as those whose diuretic dosage decreased, and that this pattern was similar in both the patients on dapagliflozin and in those randomized to placebo.

Another set of new analyses from DAPA-HF looked at the impact on dapagliflozin efficacy of background medical and device therapies for heart failure, as well as background diabetes therapies. The findings showed no signal of an interaction with background therapies. “The effects of dapagliflozin are incremental and complimentary to conventional therapies for HFrEF,” concluded Lars Kober, MD, a professor and heart failure physician at Copenhagen University Hospital.

DAPA-CKD was funded by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. McMurray’s employer, Glasgow University, has received payments from AstraZeneca and several other companies to compensate for his time overseeing various clinical trials. Dr. Kober has received honoraria for speaking on behalf of several companies including AstraZeneca.
