In Case You Missed It: COVID
COVID isolated people. Long COVID makes it worse
A year ago in December, mapping specialist Whitney Tyshynski, 35, was working out 5 days a week with a personal trainer near her home in Alberta, Canada, doing 5k trail runs, lifting heavy weights, and feeling good. Then, in January she got COVID-19. The symptoms never went away.
Nowadays, Ms. Tyshynski needs a walker to retrieve her mail, a half-block trip she can’t make without fear of fainting. Because she gets dizzy when she drives, she rarely goes anywhere in her car. Going for a dog walk with a friend means sitting in a car and watching the friend and the dogs in an open field. And since fainting at Costco during the summer, she’s afraid to shop by herself.
Because she lives alone and her closest relatives are an hour and a half away, Ms. Tyshynski is dependent on friends. But she’s reluctant to lean on them because they already have trouble understanding how debilitating her lingering symptoms can be.
“I’ve had people pretty much insinuate that I’m lazy,” she says.
There’s no question that COVID-19 cut people off from one another. But for those like Ms. Tyshynski who have long COVID, that disconnect has never ended. that the condition is real.
At worst, as Ms. Tyshynski has discovered, people don’t take it seriously and accuse those who have it of exaggerating their health woes. In that way, long COVID can be as isolating as the original illness.
“Isolation in long COVID comes in various forms and it’s not primarily just that physical isolation,” says Yochai Re’em, MD, a psychiatrist in private practice in New York who has experienced long COVID and blogs about the condition for Psychology Today. “A different yet equally challenging type of isolation is the emotional isolation, where you need more emotional support, connection with other people who can appreciate what it is you are going through without putting their own needs and desires onto you – and that can be hard to find.”
It’s hard to find in part because of what Dr. Re’em sees as a collective belief that anyone who feels bad should be able to get better by exercising, researching, or going to a doctor.
“Society thinks you need to take some kind of action and usually that’s a physical action,” he says. “And that attitude is tremendously problematic in this illness because of the postexertional malaise that people experience: When people exert themselves, their symptoms get worse. And so the action that people take can’t be that traditional action that we’re used to taking in our society.”
Long COVID patients often have their feelings invalidated not just by friends, loved ones, and extended family, but by health care providers. That can heighten feelings of isolation, particularly for people who live alone, says Jordan Anderson, DO, a neuropsychiatrist and assistant professor of psychiatry at Oregon Health & Science University in Portland.
The first patients Dr. Anderson saw as part of OHSU’s long COVID program contracted the virus in February 2020. Because the program addresses both the physical and mental health components of the condition, Dr. Anderson has seen a lot of people whose emotional challenges are similar to those Ms. Tyshynski faces.
“I think there’s a lack of understanding that leads to people just not necessarily taking it seriously,” he says. “Plus, the symptoms of long COVID do wax and wane. They’re not static. So people can be feeling pretty good one day and be feeling terrible the next. There’s some predictability to it, but it’s not absolutely predictable. It can be difficult for people to understand.”
Both Dr. Anderson and Dr. Re’em stress that long COVID patients need to prioritize their own energy regardless of what they’re being told by those who don’t understand the illness. Dr. Anderson offers to speak to his patients’ spouses to educate them about the realities of the condition because, he says, “any kind of lack of awareness or understanding in a family member or close support could potentially isolate the person struggling with long COVID.”
Depending on how open-minded and motivated a friend or relative is, they might develop more empathy with time and education, Dr. Re’em says. But for others, dealing with a confusing, unfamiliar chronic illness can be overwhelming and provoke anxiety.
“The hopelessness is too much for them to sit with, so instead they say things like ‘just push through it,’ or ‘just do X, Y, and Z,’ because psychologically it’s too much for them to take on that burden,” he says.
The good news is that there are plenty of web-based support groups for people with long COVID, including Body Politic (which Dr. Re’em is affiliated with), Survivor Corps, and on Facebook. “The patient community with this illness is tremendous, absolutely tremendous,” Dr. Re’em says. “Those people can be found and they can support each other.”
Some long COVID clinics run groups, as do individual practitioners such as Dr. Re’em, although those can be challenging to join. For instance, Dr. Re’em’s are only for New York state residents.
The key to finding a group is to be patient, because finding the right one takes time and energy.
“There are support groups that exist, but they are not as prevalent as I would like them to be,” Dr. Anderson says.
OHSU had an educational support group run by a social worker affiliated with the long COVID hub, but when the social worker left the program, the program was put on hold.
There’s a psychotherapy group operating out of the psychiatry department, but the patients are recruited exclusively from Dr. Anderson’s clinic and access is limited.
“The services exist, but I think that generally they’re sparse and pretty geographically dependent,” Dr. Anderson says. “I think you’d probably more likely be able to find something like this in a city or an area that has an academic institution or a place with a lot of resources rather than out in a rural community.”
Ms. Tyshynski opted not to join a group for fear it would increase the depression and anxiety that she had even before developing long COVID. When she and her family joined a cancer support group when her father was ill, she found it more depressing than helpful. Where she has found support is from the cofounder of the animal rescue society where she volunteers, a woman who has had long COVID for more than 2 years and has been a source of comfort and advice.
It’s one of the rare reminders Ms. Tyshynski has that even though she may live alone, she’s not completely alone. “Other people are going through this, too,” she says. “It helps to remember that.”

COVID update: ASH experts discuss thrombosis, immunity
NEW ORLEANS –
In a presidential symposium at the annual meeting of the American Society of Hematology, La Jolla Institute of Immunology scientist Shane Crotty, PhD, explained that COVID-19 has a “superpower” that allows it to be “extraordinarily stealthy.”
The virus, he said, can sneak past the body’s innate immune system, which normally responds to viral invaders within minutes to hours. “This is why you have people with high viral loads who are presymptomatic. Their innate immune system hasn’t even recognized that these people are infected.”
The adaptive immune system kicks in later. As Dr. Crotty noted, adaptive immunity is composed of three branches: B cells (the source of antibodies), CD4 “helper” T cells, and CD8 “killer” T cells. In the first year of COVID-19, his team tracked 188 subjects post infection in what he said was the largest study of its kind ever for any viral infection.
“In 8 months, 95% of people who had been infected still had measurable immune memory. In fact, most of them had multiple different compartments of immune memory still detectable, and it was likely that these individuals would still have that memory years into the future. Based on that, we made the prediction that most people who have had COVID-19 would likely be protected from reinfection – at least by severe infections – for 3 years into the future. That prediction has widely held up even in the presence of variants which weren’t around at the time.”
How do vaccines fit into the immunity picture? Dr. Crotty’s lab has tracked subjects who received 4 vaccines – Moderna, Pfizer/BioNTech, Janssen/Johnson & Johnson, and Novavax. Researchers found that the mRNA vaccines, Moderna and Pfizer/BioNTech, “are fantastic at eliciting neutralizing antibodies quickly, but then they drop off rapidly at two doses and actually continue to drop for 10 months.”
Still, he said, “when we take a look at 6 months, actually the vaccines are doing pretty incredibly well. If we compare them to an average infected individual, the mRNA vaccines all have higher neutralizing antibody titers.”
What’s happening? According to Dr. Crotty, B cells are “making guesses about what other variants might look like.” But he said research suggests that an important component of this process – germinal centers – aren’t made in some vaccinated people who are immunocompromised. (Germinal centers have been described as “microbial boot camps” for B cells.)
The good news, Dr. Crotty noted, is that a greater understanding of how COVID-19 penetrates various layers of adaptive immune defenses will lead to better ways to protect the immunocompromised. “If you think about immunity in this layered defense way, there are various ways that it could be enhanced for individuals in different categories,” he said.
Hematologist Beverley J. Hunt, MD, OBE, of St. Thomas’ Hospital/King’s Healthcare Partners in London, spoke at the ASH presidential symposium about blood clots and COVID-19. As she noted, concern arose about vaccine-related blood clots. A British team “managed quickly to come up with a diagnostic criteria,” she said. “We looked at nearly 300 patients and essentially came up with a scoring system.”
The diagnostic criteria was based on an analysis of definite or probable cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) – all related to the AstraZeneca vaccine. The criteria appeared in a 2021 study in the New England Journal of Medicine.
The report’s data didn’t allow it to compare the efficacy of anticoagulants. However, Dr. Hunt noted that clinicians turned to plasma exchange in patients with low platelet counts and extensive thrombosis. The report stated “survival after plasma exchange was 90%, considerably better than would be predicted given the baseline characteristics.”
“Now we’re following up,” Dr. Hunt said. One question to answer: Is long-term anticoagulation helpful? “We have many patients,” she said, “who are taking an anti-platelet factor out of habit.”

How to have a safer and more joyful holiday season
This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.
Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.
During the first week of December, cases of influenza were rising across the country1 and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
Influenza
Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.
RSV
In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.2
COVID-19
Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.
There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.
If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.3
With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.
Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
In summary
Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.
Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.
During the first week of December, cases of influenza were rising across the country1 and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.
Influenza
Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.
RSV
In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.2
COVID-19
Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.
There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.
If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.3
With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.
Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
In summary
Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

Cardiac injury caused by COVID-19 less common than thought
The study examined cardiac MRI scans in 31 patients before and after having COVID-19 infection and found no new evidence of myocardial injury in the post-COVID scans relative to the pre-COVID scans.
“To the best of our knowledge this is the first cardiac MRI study to assess myocardial injury pre- and post-COVID-19,” the authors stated.
They say that while this study cannot rule out the possibility of rare events of COVID-19–induced myocardial injury, “the complete absence of de novo late gadolinium enhancement lesions after COVID-19 in this cohort indicates that outside special circumstances, COVID-19–induced myocardial injury may be much less common than suggested by previous studies.”
The study was published online in JACC: Cardiovascular Imaging.
Coauthor Till F. Althoff, MD, Cardiovascular Institute, Clínic–University Hospital Barcelona, said in an interview that previous reports have found a high rate of cardiac lesions in patients undergoing imaging after having had COVID-19 infection.
“In some reports, this has been as high as 80% of patients even though they have not had severe COVID disease. These reports have been interpreted as showing the majority of patients have some COVID-induced cardiac damage, which is an alarming message,” he commented.
However, he pointed out that the patients in these reports did not undergo a cardiac MRI scan before they had COVID-19 so it wasn’t known whether these cardiac lesions were present before infection or not.
To try and gain more accurate information, the current study examined cardiac MRI scans in the same patients before and after they had COVID-19.
The researchers, from an arrhythmia unit, made use of the fact that all their patients have cardiac MRI data, so they used their large registry of patients in whom cardiac MRI had been performed, and cross referenced this to a health care database to identify those patients who had confirmed COVID-19 after they obtaining a cardiac scan at the arrhythmia unit. They then conducted another cardiac MRI scan in the 31 patients identified a median of 5 months after their COVID-19 infection.
“These 31 patients had a cardiac MRI scan pre-COVID and post COVID using exactly the same scanner with identical sequences, so the scans were absolutely comparable,” Dr. Althoff noted.
Of these 31 patients, 7 had been hospitalized at the time of acute presentation with COVID-19, of whom 2 required intensive care. Most patients (29) had been symptomatic, but none reported cardiac symptoms.
Results showed that, on the post–COVID-19 scan, late gadolinium enhancement lesions indicative of residual myocardial injury were encountered in 15 of the 31 patients (48%), which the researchers said is in line with previous reports.
However, intraindividual comparison with the pre–COVID-19 cardiac MRI scans showed all these lesions were preexisting with identical localization, pattern, and transmural distribution, and thus not COVID-19 related.
Quantitative analyses, performed independently, detected no increase in the size of individual lesions nor in the global left ventricular late gadolinium enhancement extent.
Comparison of pre- and post COVID-19 imaging sequences did not show any differences in ventricular functional or structural parameters.
“While this study only has 31 patients, the fact that we are conducting intra-individual comparisons, which rules out bias, means that we don’t need a large number of patients for reliable results,” Dr. Althoff said.
“These types of lesions are normal to see. We know that individuals without cardiac disease have these types of lesions, and they are not necessarily an indication of any specific pathology. I was kind of surprised by the interpretation of previous data, which is why we did the current study,” he added.
Dr. Althoff acknowledged that some cardiac injury may have been seen if much larger numbers of patients had been included. “But I think we can say from this data that COVID-induced cardiac damage is much less of an issue than we may have previously thought,” he added.
He also noted that most of the patients in this study had mild COVID-19, so the results cannot be extrapolated to severe COVID-19 infection.
However, Dr. Althoff pointed out that all the patients already had atrial fibrillation, so would have been at higher risk of cardiac injury from COVID-19.
“These patients had preexisting cardiac risk factors, and thus they would have been more susceptible to both a more severe course of COVID and an increased risk of myocardial damage due to COVID. The fact that we don’t find any myocardial injury due to COVID in this group is even more reassuring. The general population will be at even lower risk,” he commented.
“I think we can say that, in COVID patients who do not have any cardiac symptoms, our study suggests that the incidence of cardiac injury is very low,” Dr. Althoff said.
“Even in patients with severe COVID and myocardial involvement reflected by increased troponin levels, I wouldn’t be sure that they have any residual cardiac injury. While it has been reported that cardiac lesions have been found in such patients, pre-COVID MRI scans were not available so we don’t know if they were there before,” he added.
“We do not know the true incidence of cardiac injury after COVID, but I think we can say from this data that it is definitely not anywhere near the 40%-50% or even greater that some of the previous reports have suggested,” he stated.
Dr. Althoff suggested that, based on these data, some of the recommendations based on previous reports such the need for follow-up cardiac scans and caution about partaking in sports again after COVID-19 infection, are probably not necessary.
“Our data suggest that these concerns are unfounded, and we need to step back a bit and stop alarming patients about the risk of cardiac damage after COVID,” he said. “Yes, if patients have cardiac symptoms during or after COVID infection they should get checked out, but I do not think we need to do a cardiac risk assessment in patients without cardiac symptoms in COVID.”

FROM JACC: CARDIOVASCULAR IMAGING
Children and COVID: New-case counts offer dueling narratives
New COVID-19 cases in children jumped by 66% during the first 2 weeks of December after an 8-week steady period lasting through October and November, according to the American Academy of Pediatrics and the Children’s Hospital Association.
and totaling less than 29,000 for the week of Nov. 25 to Dec. 1. That increase of almost 19,000 cases is the largest over a 2-week period since late July, the AAP and CHA said in their weekly COVID report based on data collected from state and territorial health department websites.
[This publication has been following the AAP/CHA report since the summer of 2020 and continues to share the data for the sake of consistency, but it must be noted that a number of states are no longer updating their public COVID dashboards. As a result, there is now a considerable discrepancy between the AAP/CHA weekly figures and those reported by the Centers for Disease Control and Prevention, which has no such limitations on state data.]
The situation involving new cases over the last 2 weeks is quite different from the CDC’s perspective. The agency does not publish a weekly count, instead offering cumulative cases, which stood at almost 16.1 million as of Dec. 14. Calculating a 2-week total puts the new-case count for Dec. 1-14 at 113,572 among children aged 0-17 years. That is higher than the AAP/CHA count (88,629) for roughly the same period, but it is actually lower than the CDC’s figure (161,832) for the last 2 weeks of November.
The CDC data, in other words, suggest that new cases have gone down in the last 2 weeks, while the AAP and CHA, with their somewhat limited perspective, announced that new cases have gone up.
One COVID-related measure from the CDC that is not contradicted by other sources is hospitalization rates, which had climbed from 0.16 new admissions in children aged 0-17 years with confirmed COVID per 100,000 population on Oct. 22 to 0.29 per 100,000 on Dec. 9. Visits to the emergency department with diagnosed COVID, meanwhile, have been fairly steady so far through December in children, according to the CDC.

One COVID-related measure from the CDC that is not contradicted by other sources is hospitalization rates, which had climbed from 0.16 new admissions in children aged 0-17 years with confirmed COVID per 100,000 population on Oct. 22 to 0.29 per 100,000 on Dec. 9. Visits to the emergency department with diagnosed COVID, meanwhile, have been fairly steady so far through December in children, according to the CDC.
COVID booster shot poll: People ‘don’t think they need one’
Now, a new poll shows why so few people are willing to roll up their sleeves again.
The most common reasons people give for not getting the latest booster shot is that they “don’t think they need one” (44%) and they “don’t think the benefits are worth it” (37%), according to poll results from the Kaiser Family Foundation.
The data comes amid announcements by the Centers for Disease Control and Prevention that boosters reduced COVID-19 hospitalizations by up to 57% for U.S. adults and by up to 84% for people age 65 and older. Those figures are just the latest in a mountain of research reporting the public health benefits of COVID-19 vaccines.
Despite all of the statistical data, health officials’ recent vaccination campaigns have proven far from compelling.
So far, just 15% of people age 12 and older have gotten the latest booster, and 36% of people age 65 and older have gotten it, the CDC’s vaccination trackershows.
Since the start of the pandemic, 1.1 million people in the U.S. have died from COVID-19, with the number of deaths currently rising by 400 per day, The New York Times COVID tracker shows.
Many experts continue to note the need for everyone to get booster shots regularly, but some advocate that perhaps a change in strategy is in order.
“What the administration should do is push for vaccinating people in high-risk groups, including those who are older, those who are immunocompromised and those who have comorbidities,” Paul Offitt, MD, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told CNN.
Federal regulators have announced they will meet Jan. 26 with a panel of vaccine advisors to examine the current recommended vaccination schedule as well as look at the effectiveness and composition of current vaccines and boosters, with an eye toward the make-up of next-generation shots.
Vaccines are the “best available protection” against hospitalization and death caused by COVID-19, said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in a statement announcing the planned meeting.
“Since the initial authorizations of these vaccines, we have learned that protection wanes over time, especially as the virus rapidly mutates and new variants and subvariants emerge,” he said. “Therefore, it’s important to continue discussions about the optimal composition of COVID-19 vaccines for primary and booster vaccination, as well as the optimal interval for booster vaccination.”

Multiple myeloma diagnosed more via emergency care during COVID
The study covered in this summary was published on Research Square as a preprint and has not yet been peer reviewed.
Key takeaway
Why this matters
While trying to avoid COVID-19 infection, patients ultimately diagnosed with multiple myeloma may have delayed interactions with healthcare professionals and consequently delayed their cancer diagnosis.
Study design
Researchers collected data on newly diagnosed patients with multiple myeloma from January 2019 until July 2021 across five institutions (three universities and two hospitals) in England. In total, 323 patients with multiple myeloma were identified.
Patients were divided into two groups: those diagnosed between Jan. 1, 2019, until Jan. 31, 2020, or pre-COVID, and those diagnosed from Feb. 1, 2020, to July 31, 2021, or post COVID.
Key results
Among all patients, 80 (24.8%) were diagnosed with smoldering multiple myeloma and 243 (75.2%) were diagnosed with multiple myeloma requiring treatment.
Significantly more patients in the post-COVID group were diagnosed with myeloma through the emergency route (45.5% post COVID vs. 32.7% pre-COVID; P = .03).
Clinical complications leading to emergency admission prior to a myeloma diagnosis also differed between the two cohorts: Acute kidney injury accounted for most emergency admissions in the pre-COVID cohort while skeletal-related events, including spinal cord compression, were the major causes for diagnosis through the emergency route in the post-COVID cohort.
Patients who were diagnosed with symptomatic myeloma pre-COVID were more likely to be treated with a triplet rather than doublet combination compared with those diagnosed in the post-COVID period (triplet pre-COVID 79.1%, post COVID 63.75%; P = .014).
Overall survival at 1 year was not significantly different between the pre-COVID and post-COVID groups: 88.2% pre-COVID, compared with 87.8% post COVID.
Overall, the authors concluded that the COVID pandemic “resulted in a shift in the symptomatology, disease burden, and routes of diagnosis of patients presenting with myeloma” and “this may have significant consequences” over the long term.
Limitations
The study does not provide a clear time frame of delays in diagnosis.
Disclosures
The study authors did not report any conflicts of interest.

Rise of ‘alarming’ subvariants of COVID ‘worrisome’ for winter
It’s a story perhaps more appropriate for Halloween than for the festive holiday season, given its scary implications.
Not too dire so far, until the researchers’ other findings are considered.
The BQ.1, BQ1.1, XBB, and XBB.1 subvariants are the most resistant to neutralizing antibodies, researcher Qian Wang, PhD, and colleagues wrote in a study published online in the journal Cell. This means people have no or “markedly reduced” protection against infection from these four strains, even if they’ve already had COVID-19 or are vaccinated and boosted multiple times, including with a bivalent vaccine.
On top of that, all available monoclonal antibody treatments are mostly or completely ineffective against these subvariants.
What does that mean for the immediate future? The findings are definitely “worrisome,” said Eric Topol, MD, founder and director of the Scripps Translational Research Institute in La Jolla, Calif.
But evidence from other countries, specifically Singapore and France, show that at least two of these variants turned out not to be as damaging as expected, likely because of high numbers of people vaccinated or who survived previous infections, he said.
Still, there is little to celebrate in the new findings, except that COVID-19 vaccinations and prior infections can still reduce the risk for serious outcomes such as hospitalization and death, the researchers wrote.
In fact, Centers for Disease Control and Prevention data released on Dec. 16 shows that people who have received four shots of the original COVID-19 vaccines as well as the bivalent booster were 57% less likely to visit an urgent care clinic or emergency room, regardless of age.
It comes at a time when BQ.1 and BQ.1.1 account for about 70% of the circulating variants, data show. In addition, hospitalizations are up 18% over the past 2 weeks and COVID-19 deaths are up 50% nationwide, The New York Times reported.
Globally, in many places, an “immunity wall” that has been built, Dr. Topol said. That may not be the case in the United States.
“The problem in the United States, making it harder to predict, is that we have a very low rate of recent boosters, in the past 6 months, especially in seniors,” he said. For example, only 36% of Americans aged 65 years and older, the group with highest risk, have received an updated bivalent booster.
An evolving virus
The subvariants are successfully replacing BA.5, which reigned as one of the most common Omicron variants over the past year. The latest CDC data show that BA.5 now accounts for only about 10% of the circulating virus. The researchers wrote: “This rapid replacement of virus strains is raising the specter of yet another wave of infections in the coming months.”
BQ.1 and BQ.1.1 evolved directly from BA.5 – adding more and some novel mutations to the SARS-CoV-2 virus. XBB and XBB.1 are the “offspring” of a combination of two other strains, known as BJ.1 and BA.2.75.
The story sounds familiar to the researchers. “The rapid rise of these subvariants and their extensive array of spike mutations are reminiscent of the appearance of the first Omicron variant last year, thus raising concerns that they may further compromise the efficacy of current COVID-19 vaccines and monoclonal antibody therapeutics,” they wrote. “We now report findings that indicate that such concerns are, sadly, justified, especially so for the XBB and XBB.1 subvariants.”
To figure out how effective existing antibodies could be against these newer subvariants, Dr. Wang and colleagues used blood samples from five groups of people. They tested serum from people who had three doses of the original COVID-19 vaccine, four doses of the original vaccine, those who received a bivalent booster, people who experienced a breakthrough infection with the BA.2 Omicron variant, and those who had a breakthrough with a BA.4 or BA.5 variant.
Adding the new subvariants to these serum samples revealed that the existing antibodies in the blood were ineffective at wiping out or neutralizing BQ.1, BQ.1.1, XBB, and XBB.1.
The BQ.1 subvariant was six times more resistant to antibodies than BA.5, its parent strain, and XBB.1 was 63 times more resistant compared with its predecessor, BA.2.
This shift in the ability of vaccines to stop the subvariants “is particularly concerning,” the researchers wrote.
Wiping out treatments too
Dr. Wang and colleagues also tested how well a panel of 23 different monoclonal antibody drugs might work against the four subvariants. The therapies all worked well against the original Omicron variant and included some approved for use through the Food and Drug Administration emergency use authorization (EUA) program at the time of the study.
They found that 19 of these 23 monoclonal antibodies lost effectiveness “greatly or completely” against XBB and XBB.1, for example.
This is not the first time that monoclonal antibody therapies have gone from effective to ineffective. Previous variants have come out that no longer responded to treatment with bamlanivimab, etesevimab, imdevimab, casirivimab, tixagevimab, cilgavimab, and sotrovimab. Bebtelovimab now joins this list and is no longer available from Eli Lilly under EUA because of this lack of effectiveness.
The lack of an effective monoclonal antibody treatment “poses a serious problem for millions of immunocompromised individuals who do not respond robustly to COVID-19 vaccines,” the researchers wrote, adding that “the urgent need to develop active monoclonal antibodies for clinical use is obvious.”
A limitation of the study is that the work is done in blood samples. The effectiveness of COVID-19 vaccination against the BQ and XBB subvariants should be evaluated in people in clinical studies, the authors noted.
Also, the current study looked at how well antibodies could neutralize the viral strains, but future research, they added, should look at how well “cellular immunity” or other aspects of the immune system might protect people.
Going forward, the challenge remains to develop vaccines and treatments that offer broad protection as the coronavirus continues to evolve.
In an alarming ending, the researchers wrote: “We have collectively chased after SARS-CoV-2 variants for over 2 years, and yet, the virus continues to evolve and evade.”

U.S. sees most flu hospitalizations in a decade
But the number of deaths and outpatient visits for flu or flu-like illnesses was down slightly from the week before, the CDC said in its weekly FluView report.
There were almost 26,000 new hospital admissions involving laboratory-confirmed influenza over those 7 days, up by over 31% from the previous week, based on data from 5,000 hospitals in the HHS Protect system, which tracks and shares COVID-19 data.
The cumulative hospitalization rate for the 2022-2023 season is 26.0 per 100,000 people, the highest seen at this time of year since 2010-2011, the CDC said, based on data from its Influenza Hospitalization Surveillance Network, which includes hospitals in select counties in 13 states.
At this point in the 2019-2020 season, just before the COVID-19 pandemic began, the cumulative rate was 3.1 per 100,000 people, the CDC’s data show.
On the positive side, the proportion of outpatient visits for influenza-like illness dropped slightly to 7.2%, from 7.5% the week before. But these cases from the CDC’s Outpatient Influenza-like Illness Surveillance Network are not laboratory confirmed, so the data could include people with the flu, COVID-19, or respiratory syncytial virus.
The number of confirmed flu deaths for the week of Nov. 27 to Dec. 3 also fell slightly from the last full week of November, 246 vs. 255, but the number of pediatric deaths rose from 2 to 7, and total deaths in children are already up to 21 for 2022-2023. That’s compared to 44 that were reported during all of the 2021-2022 season, the CDC said.
“So far this season, there have been at least 13 million illnesses, 120,000 hospitalizations, and 7,300 deaths from flu,” the agency estimated.

But the number of deaths and outpatient visits for flu or flu-like illnesses was down slightly from the week before, the CDC said in its weekly FluView report.
There were almost 26,000 new hospital admissions involving laboratory-confirmed influenza over those 7 days, up by over 31% from the previous week, based on data from 5,000 hospitals in the HHS Protect system, which tracks and shares COVID-19 data.
The cumulative hospitalization rate for the 2022-2023 season is 26.0 per 100,000 people, the highest seen at this time of year since 2010-2011, the CDC said, based on data from its Influenza Hospitalization Surveillance Network, which includes hospitals in select counties in 13 states.

As COVID treatments dwindle, are new ones waiting in the wings?
It was the last monoclonal antibody treatment standing. But less than 10 months after the U.S. Food and Drug Administration gave bebtelovimab its emergency use authorization (EUA) to fight COVID-19, it earlier this month de-authorized it, just as it had for other monoclonal antibody treatments, and for the same reason:
Bebtelovimab couldn’t neutralize the Omicron subvariants BQ.1 and BQ.1.1, the cause of nearly 60% of COVID cases nationally as of November 30.
Next on the chopping block, some predict, will be Evusheld, the combination of tixagevimab and cilgavimab given as a preventive monoclonal antibody to people who are immunocompromised and at high risk of contracting COVID and to those who can’t take the vaccine. In October, the FDA warned that Evusheld was not neutralizing circulating COVID variants.
As the options for treating and preventing COVID decline, will companies rally quickly to develop new ones, or cut their losses in developing treatments that may work for only a few months, given the speed of viral mutations?
But although monoclonal antibody treatments are off the table, at least for now, antiviral drugs – including Paxlovid – are still very much available, and some say underused.
Others suggest it’s time to resurrect interest in convalescent plasma, a treatment used early in the pandemic before drugs or vaccines were here and still authorized for use in those who are immunosuppressed or receiving immunosuppressive treatment.
And on the prevention front, staying up to date with booster vaccines, masking, and taking other precautions should be stressed more, others say, regardless of the number of treatment options, and especially now, as cases rise and people gather for the winter holidays.
‘A major setback’
The bebtelovimab de-authorization was “a major setback,” but an understandable one, said Arturo Casadevall, MD, PhD, professor and chair of molecular microbiology and immunology at the Johns Hopkins Bloomberg School of Public Health in Baltimore. “Monoclonal antibodies are great drugs. We are in an unfortunate situation in that they are vulnerable to changes in the virus” and can’t offer long-lasting protection.
Supplies of bebtelovimab will be retained, according to the FDA, in case variants susceptible to it return.
“What happened to bebtelovimab is no surprise,” agreed Amesh Adalja, MD, senior scholar at Johns Hopkins Center for Health Security. “This is what is going to happen when you are targeting a virus that mutates a lot.”
Monoclonal antibodies work by binding to the spike protein on the virus surface to prevent it from entering cells.
However, Dr. Adalja doesn’t view the disappearance of monoclonal antibody treatments as a major setback. Monoclonal antibodies were not the primary way COVID was treated, he said.
While he does believe it’s important that more monoclonal antibody treatments be developed, “I think it’s important to remember we still have Paxlovid while everyone is lamenting the loss of bebtelovimab.’’
Antivirals: What’s here, what’s coming
Compared with monoclonal antibodies, “Paxlovid remains a much easier drug to give,” Dr. Adalja told this news organization, because it is taken orally, not intravenously.
And it’s effective. In a recent study, researchers found that adults diagnosed with COVID given Paxlovid within 5 days of diagnosis had a 51% lower hospitalization rate within the next 30 days than those not given it. Another study shows it could also reduce a person’s risk of developing long COVID by 26%.
Paxlovid is underused, Dr. Adalja said, partly because the rebound potential got more press than the effectiveness. When a celebrity got rebound from Paxlovid, he said, that would make the news, overshadowing the research on its effectiveness.
Besides Paxlovid, the antivirals remdesivir (Veklury), given intravenously for 3 days, and molnupiravir (Lagevrio), taken orally, are also still available. Antivirals work by targeting specific parts of the virus to prevent it from multiplying.
In the lab, remdesivir, molnupiravir, and another antiviral, nirmatrelvir, all appear to be effective against both BQ.1.1 (a BA.5 subvariant) and XBB (a BA.2 subvariant), both rapidly rising in the United States, according to a report last week in the New England Journal of Medicine.
The researchers also tested several monoclonal antibodies and found they did not neutralize either of the subvariants BQ.1.1 and XBB.
A new oral antiviral, Xocova (ensitrelvir fumaric acid), from Japanese manufacturer Shionogi, received emergency approval in Japan on November 22. It’s taken once a day for 5 days. The goal is to expand access to it globally, according to the company.
Pardes Biosciences launched a phase 2 trial in September for its oral antiviral drug (PBI-0451), under study as a treatment and preventive for COVID. It expects data by the first quarter of 2023.
Pfizer, which makes Paxlovid, has partnered with Clear Creek Bio to develop another oral antiviral COVID drug.
Other approaches
A receptor protein known as ACE2 (angiotensin-converting enzyme 2) is the main “doorway” that SARS-CoV-2 uses to enter and infect cells.
Dana-Farber Cancer Institute scientists are developing a “decoy” drug that works by mimicking the ACE2 receptor on the surface of cells; when the virus tries to bind to it, the spike protein is destroyed. Human trials have not yet started.
Other researchers are investigating whether an already-approved drug used to treat a liver disease, Actigall (UDCA/ursodeoxycholic acid), could protect against COVID infection by reducing ACE2.
So far, the researchers have found in early research that people taking UDCA for liver conditions were less likely than those not taking the drug to have severe COVID. They also found that UDCA reduced SARS-CoV-2 infection in human lungs maintained outside the body.
Monoclonal antibody treatments?
After the FDA decision to withdraw the bebtelovimab EUA, which Eli Lilly said it agreed with, the company issued a statement, promising it wasn’t giving up on monoclonal antibody treatments.
“Lilly will continue to search and evaluate monoclonal antibodies to identify potential candidates for clinical development against new variants,” it read in part.
AstraZeneca, which makes Evusheld, is also continuing to work on monoclonal antibody development. According to a spokesperson, “We are also developing a new long-acting antibody combination – AZD5156 – which has been shown in the lab to neutralize emerging new variants and all known variants to date. We are working to accelerate the development of AZD5156 to make it available at the end of 2023.”
The AstraZeneca spokesperson said he could share no more information about what the combination would include.
A convalescent plasma comeback?
Although Paxlovid can help, there are many contraindications to it, such as drug-drug interactions, Dr. Casadevall told this news organization. And now that the monoclonal antibody treatments have been paused, convalescent plasma “is the only antibody-based therapy that is reliably available. Convalescent plasma includes thousands of different antibodies.”
With his colleagues, Dr. Casadevall evaluated plasma samples from 740 patients. Some had received booster vaccines and been infected with Omicron, others had received boosters and not been infected, and still others had not been vaccinated and became infected.
In a report (not yet peer-reviewed), they found the plasma from those who had been infected or boosted within the past 6 months neutralized the new Omicron variants BQ.1.1, XBB.1, and BF.7.
A push for boosters, masks
To get through the coming months, taking precautions like masking and distancing and staying up to date on booster vaccinations, especially for older adults, can make a difference, other experts say.
In a Twitter thread in early December, Peter Hotez, MD, PhD, professor of pediatrics and molecular virology and microbiology at Baylor College of Medicine, Houston, urged people to take COVID seriously as holiday parties and gatherings occur.
“The single most impactful thing you can do is get your bivalent booster,” he tweeted, as well as give your kids the booster, citing preliminary research that the bivalent mRNA booster broadens immunity against the Omicron subvariants.
For seniors, he said, ‘‘if you get breakthrough COVID, [it’s] really important to get Paxlovid.” Masks will help not only for COVID but also influenza, respiratory syncytial virus (RSV), and other conditions.
Mitigation measures have largely been abandoned, according to Eric Topol, MD, director of the Scripps Research Translational Institute, La Jolla, Calif., and editor-in-chief of Medscape. In an op-ed in the Los Angeles Times, and on his Twitter feed, he reminds people about masking and urges people to get the bivalent booster.
According to the Centers for Disease Control and Prevention, as of Dec. 8, only 13.5% of people aged 5 and older have gotten an updated booster, despite research that shows an increase in antibodies to BQ.1.1. Recent research has found that the bivalent booster increases antibodies to BQ.1.1 by up to 10-fold, Dr. Topol said.
Dr. Adalja is on advisory boards for Shionogi, GSK, and Pardes. Dr. Casadevall reports no relevant financial relationships.
