Tony Marks in Pinehurst and Brooke Keaton in Charlotte both lived orderly, productive lives two years ago. That was clearly reflected in their steady jobs and close family ties.
However, their experiences with the long-term effects of infection with the COVID-19 virus have touched and in many cases devastated nearly every other aspect of each of their days.
Marks and Keaton don’t know each other, but both have worked with John M. Baratta, who practices physical medicine and rehabilitation at the University of North Carolina COVID Recovery Clinic. There, Baratta and his colleagues attempt to explore several paths out of these lingering, disabling after-effects of the pandemic.
“I haven’t had a day in over a year and a half that I have not hurt, that I have not been tired, that my hands just don’t feel like they have arthritis,” Marks, 55, a software executive, said during a physical therapy session at the clinic. “I just can’t explain how bad I just physically hurt, on a day-to-day basis, and there’s the fatigue, and so I know there’s gotta be something else, right? And that’s why I want to do this so badly.”
As Marks battles the lingering effects of COVID, he faces unpredictable limits on his working days. Keaton struggles with her symptoms so much that she has lost her job as a preschool teacher.
However, in the larger picture emerging from the UNC clinic and others, there are signs that help may be on the way for the patients known as COVID “long haulers” — aid in the form of new research, promising treatments, and evolving approaches to therapy.
New research holds hope
Approaches monitored at the UNC clinic include new hard science about microclots that may lie at the heart of some of long COVID’s symptoms, a potentially game-changing analysis introduced by South African researcher, Resia Pretorius.

“Her lab has demonstrated that there are circulating microclots in the blood of many people with long COVID,” Baratta explained during an interview at the Chapel Hill-based clinic. “These clots don’t necessarily block blood vessels causing stroke or heart attack. What these microclots do is trap inflammatory molecules and they prevent the breakdown of some of the inflammation.
“So these circulating microclots can cause this persistent inflammatory process. And they’ve actually, in some early clinical research, been trying to anticoagulate patients in an attempt to break down the microclots and some of their early data suggests favorable results.”
The theory of microclots’ role in the disease has created excitement as an example of a new direction, even though Pretorius’s findings were based on a relatively small sample of patients and separate research found lower levels of microclotting in the vessels of other long COVID patients.
It’s too early to know whether Pretorius’s findings will be replicated on a large scale, Baratta said, but her findings show the kind of progress that will be necessary to advance the treatment of long COVID.
Known internationally before her research on long COVID, Pretorius gave the keynote speech at a symposium on approaches to long COVID presented by UNC in Greensboro in May.
A recent study of more than 100,000 people in Scotland, regarded as authoritative because it relied on National Health Service data, found that 6 percent of people diagnosed with acute COVID-19 had not recovered at all and 42 percent had only partially recovered.
How to avoid energy deficits
Closer to home, therapists at the clinic give advice to patients on rationing their energy by comparing it to a balance on a credit card, a finite amount that must be carefully monitored lest it fall into a steep deficit. UNC clinic staffer Courtney Matrunick, who holds a doctorate in physical therapy, explained the theory about pacing to Marks during a visit to the Chapel Hill clinic. She told him that he will exhaust his energy balance more quickly as a COVID long hauler.
“Every morning you’re waking up and getting $100. It may not feel like you’re getting $100, but you’re getting this $100,” Matrunick said during a therapy session in a clinic examination room. “But you’re using more. So now you’re in a deficit. Right? So the next morning — and this is just super simplified — you have $100 and you use $150. You’re in a $50 deficit already.
“Then the next day you wake up and you don’t even have the energy to pay off that bill. But you still have to survive. You still have to eat, you still have to do everything, but you feel like, ‘I can’t get out of bed,’” she said. “And that’s because you literally have used everything.”
Matrunick said that’s often when a long COVID patient ends up needing to stay in bed for a couple of days to catch up.
Matrunick cites California physical therapist and academic Todd Davenport as her source for the credit-card analogy. More specialized information is available on this podcast. Davenport recommends carefully tailoring activities and any exercise to avoid making symptoms worse after exertion.
Oxygen deprivation may cause long-haul symptoms
Researcher Pretorius asserts that some clinicians have made incorrect diagnoses in cases of long COVID because most tests don’t pick up on the presence of inflammation hidden within the microclots she’s studying.
“Many people feel that they go to a clinician and they are misdiagnosed,” Pretorius said during a video interview with the PolyBio Research Foundation. “Many of the typical laboratory blood-type analyses will not pick up any differences in inflammatory markers. And the patient has become very desperate as the condition is ascribed to a psychological issue.”
In Pretorius’s research, two infusions of the anticoagulant drug succeeded in dissolving the microclots. This allowed treatment of the inflammation that can cause damage to blood vessels and prevent oxygen – known as hypoxia – from reaching cells.
“And if you look at the (long COVID) symptoms closely, it all comes back to a hypoxia of certain organ systems — whether it’s the muscle not getting enough oxygen, whether it’s liver damage, whether it’s brain fog concentration issues,” Pretorius said. “One can all bring it back to a reason why the symptoms might happen, because of oxygen deprivation to certain areas.”
‘Where’s the part where you apologize?’
Keaton, now 42, had been a go-to teacher, mom to two girls, a wife and someone deeply involved in church with a broad community of family and friends, when she was diagnosed with COVID-19 in December 2020.
“I was a fun teacher,” Keaton said. “They knew I played music and I would say, ‘We will dance! We will have a party on the playground!’
Charlotte resident Brooke Keaton has dealt with long COVID symptoms such as fatigue and memory issues for two years. She’s seen with husband Jared and daughters Bria, 4, and Jaren, 12. Submitted photo.
“And now I can’t even walk down the steps down to my kitchen without becoming short of breath. Even now having this conversation with you, I feel myself being short of breath.”
During a phone call from Charlotte, Keaton told of how missed diagnoses caused problems in her now yearslong effort to address her post-acute COVID symptoms. She said she’s heard of similar experiences during online discussions as a part of a group of Black women facing long COVID.
Keaton described an attempt to steer her on an unproductive path by a doctor who seemed determined to act on a particular diagnosis.
“I went in explaining to her the fatigue, the memory loss, the brain fog, the issue with the numbness in my hands and my feet, and feeling vibrations,” Keaton said. “And she looked at me and she’s like, ‘I think we need to test you for sleep apnea. Has that ever been a concern?’”
“And her whole thing was like, ‘I think all of this is because you have sleep apnea,’” Keaton said. So Keaton spent money on testing at home and at the physician’s office, both of which indicated she did not have sleep apnea.
“And she just kind of left it there. I’m like, ‘So we determined I don’t have sleep apnea. What can we do about everything else?’” Keaton said. In response, the physician gave her pointers on how to get better sleep at night.
“So fast forward: ‘Where’s the part where you apologize to me for making an assumption, you know?’”
Adding insult to the entire process, Keaton has found her insurance coverage did not cover certain treatments and therapies that were otherwise recommended.
Another direction for the clinic involves examining the overlap between long COVID and myalgic encephalomyelitis, also called chronic fatigue syndrome, abbreviated as ME/CFS. It shares a similarity with long COVID in that doctors sometimes overlook or minimize its symptoms.
About 20 percent of long haulers may also develop chronic fatigue, Baratta said.
“ME/CFS is a syndrome which has been recognized for many decades,” Baratta said. “It is thought to in most cases be post-viral, or post-infectious in nature and many people with ME/CFS have had difficulty getting their symptoms and the syndrome recognized in the medical community.”
Examining the reasons that chronic fatigue cases are sometimes undiagnosed could reveal similar issues with recognition of long COVID, Baratta said. For one thing, many physicians are not trained to recognize these types of post-infectious disease fatiguing illnesses.
“So it’s not really on our radar when we evaluate patients,” he said. “The cases are not seen with great regularity. And that can also make it less likely for a doctor to think of it as a diagnosis.”
The subjective nature of the symptoms of the linked diseases also comes into play.
“For example, someone might come into the office and say, ‘I’m fatigued. I feel like I don’t have as much energy as I did. I am not thinking as clearly as I used to,’” he said.
“These are not as easy to diagnose issues as a heart murmur, where you could listen with a stethoscope, and a doctor could clearly hear with their own ears.”
In addition, Baratta said, a clinician may think a patient is malingering or has an agenda such as an attempt to gain disability coverage.
The range and profundity of conditions that accompany long COVID — the intense fatigue, difficulty in concentration, chronic pain, shortness of breath — make faking it seem unlikely.

Crashing on the job
A long-time professional, Marks sounds distraught and unbelieving when he describes his attempts to keep working.
“I crash every day at work,” he said. And he said there’s no rhyme or reason as to the time, it can be first thing in the morning, or in mid-afternoon.
“And when I crash, I sleep, and I’m asleep anywhere from 30 minutes to two hours. Can you imagine being asleep for two hours at work?” he asked. “And I’m sleeping so hard and my neighbors in other offices are saying, ‘Dude, you slept good because you were snoring like a freight train.’”
He said that if he’s honest with himself, he really can only get in four hours of work during an eight-hour workday.
For Keaton, her case of long COVID has meant not only the physical and mental symptoms, but also losing her job, needing to replace her work-related insurance and chipping away at her typical role as a caretaker and problem solver.
She choked up briefly when talking about her change in personal status.
“I’ve always been a positive person,” Keaton said. “I had a rough time growing up, in certain situations with my parents.
“I’m just a fighter. I know that I’m going to get better. I have faith that I’m going to get better. I know that there is a reason for me going through this and before long you know God will reveal it.”
Despite the potential of multiple research efforts, there remains no set treatment or protocol to treat the condition. Some patients at Baratta’s clinic may receive medication, some are prescribed therapy and others are given suggestions about modifying their levels of activity.

This <a target=”_blank” href=”https://www.northcarolinahealthnews.org/2022/12/05/long-covid-trials/”>article</a> first appeared on <a target=”_blank” href=”https://www.northcarolinahealthnews.org”>North Carolina Health News</a> and is republished here under a Creative Commons license.<img src=”https://i0.wp.com/www.northcarolinahealthnews.org/wp-content/uploads/2021/10/cropped-favicon02.jpg?fit=150{fe463f59fb70c5c01486843be1d66c13e664ed3ae921464fa884afebcc0ffe6c}2C150&ssl=1″ style=”width:1em;height:1em;margin-left:10px;”><img id=”republication-tracker-tool-source” src=”https://www.northcarolinahealthnews.org/?republication-pixel=true&post=44806&ga=UA-28368570-1″ style=”width:1px;height:1px;”>
Instead, frequently the most important hurdles, as the Forbes relatives noticed, are whether or not the drug enterprise has an expanded-obtain application for a unique drug and, if it does, no matter if it approves the request. There is no prerequisite for organizations to report how several requests they acknowledge, however some larger drug companies make this information and facts public.
Perhaps far more essential, it’s unidentified to what extent families’ media strategies influence these choices. This is what difficulties Arthur Caplan, a professor of bioethics at New York University’s Grossman College of Drugs. “If you have means, then you employ PR individuals, you construct your possess web-site, and you have a rather very good probability of guilting or shaming the business into supplying a little something to you,” he informed me. “I understand why people today do it, but it’s barely an equitable process.”
Dr. Caplan has pioneered a attainable answer. Operating with Janssen Prescription drugs, a portion of Johnson & Johnson, he heads an advisory committee of doctors, ethicists and community associates who assess these requests and then build a suggestion for the drug organization. Much like the U.S. procedure for organ allocation, which Dr. Caplan also served establish, this committee aims to ensure a truthful allocation of a constrained source. Drug corporations should really not be swayed to say indeed by the most sympathetic photos or pushed to say no for the reason that of a problem that a adverse end result could influence client confidence in a drug. As an alternative, the committee applies dependable conditions to each and every anonymous possible recipient and renders a final decision dependent on clinical factors rather than the pathos of a own tale, prosperity or media prominence.
This is a get started, particularly when coupled with better tracking of outcomes and enhanced schooling for clinicians about how to enroll their sufferers in clinical trials and navigate expanded accessibility if those trials aren’t a risk. A law firm by instruction, Ms. Forbes did most of this navigation and advocacy on her very own, but there are a lot of family members for whom that would not be attainable. And when clinicians’ time is a minimal source, how a great deal of this approach can they realistically just take on for a drug not nonetheless proved to perform?
That is the question powering so a lot of this discussion. How significantly do we go when the option is demise? And what is sacrificed in the procedure? “You’re holding out hope that you may be that scarce a single, that if you can just continue to be alive prolonged more than enough for the future drug, that could possibly adjust matters,” Ms. Forbes informed me, reflecting on all those final weeks.
Even though her spouse by no means did obtain the expanded-obtain drug, she does not regret that they devoted so significantly of their remaining time and energy to pursuing it. They considered that this medication would perform, she reported, but they ended up also equipped to look at a truth in which Mr. Forbes did not dwell to see it.
“Despite how it all ended, it was very good for Michael to sense positive and hopeful,” she mentioned. “It was quite great for me, due to the fact there was no stone unturned.” That is not the kind of victory they preferred, but it is something.
Cannabidiol (CBD), an energetic component in hashish, may well assistance block infection with the virus that brings about COVID-19.
But really don’t go fall a bunch of cash on CBD oils at your nearby dispensary: The attainable influence still requirements to be tested in humans. (And absolutely will not smoke marijuana to protect against coronavirus an infection.) Even if the findings do maintain up, they use to the form of health-related-grade, Food items and Drug Administration (Food and drug administration)-authorised CBD utilised to deal with seizure disorders, not the very low-potency things readily available to shoppers.
CBD is also no substitute for weapons in opposition to COVID-19 that are acknowledged to do the job, these kinds of as vaccination and significant-high-quality masks, claimed examine chief Marsha Rosner, a most cancers researcher at the University of Chicago who reports immune responses. But the scientists are hopeful that the compound could be an added instrument in the combat versus the SARS-CoV-2 virus — and maybe other viruses. So much, the group has proven that the compound can support mice struggle off COVID-19, and they’ve turned up suggestive evidence that it may possibly be encouraging human beings, also.
“We really don’t know nevertheless if CBD can reduce COVID, but we imagine our outcomes give a sturdy circumstance for conducting a scientific trial,” Rosner informed Stay Science. “That is truly our mantra: We want a scientific trial.”
Triggering worry
CBD is derived from the cannabis plant. As opposed to tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, CBD doesn’t result in a high. But it does bind to a lot more than a thousand unique receptors in the human physique, claimed Robin Duncan, a biochemist and nutritional scientist at the University of Waterloo in Ontario, who was not associated in the new analysis. This biological activity has provided it a reputation as a wellbeing supplement — CBD oils, shakes and other products and solutions are accessible all in excess of the location — but tiny about CBD’s effects on health and fitness has been analyzed or demonstrated.
Rosner and her colleagues stumbled into finding out CBD and COVID-19. They were screening compounds for cancer study, hoping to trigger an immune response in cells referred to as the host strain reaction. The host anxiety response is aspect of the innate immune reaction. It’s not specific at any certain pathogen, but when a mobile senses a threat, these types of as an invading virus, this reaction places the mobile into a defensive condition, triggering the launch of protective substances and supporting avoid the cell’s machinery from being used to replicate the virus.
“Using tobacco or vaping pot will not shield you in opposition to COVID-19.”
—Marsha Rosner
CBD seemed shockingly excellent at triggering the host worry reaction, which is essential for cells to struggle back again towards viruses, Rosner claimed, so she and her colleagues determined to study the compound from the novel coronavirus.
They started by managing human lung cells in a lab dish with CBD and then exposing them to SARS-CoV-2, the virus that results in COVID-19. They uncovered that when compared with untreated cells, the CBD-dosed cells were being substantially superior at staving off an infection. The exact held real for monkey kidney cells, which are susceptible to the virus. It also held correct for the alpha, beta and gamma variants of the coronavirus. (Delta and omicron were not obtainable when the review was performed, Rosner explained.)
“We demonstrate that CBD can stop replication of SARS-COV2 in cells in a dish and that it functions at the very least up to 15 hrs immediately after an infection, so that suggests it could possibly be powerful even at early instances just after viruses enter cells,” Rosner stated.
Placing CBD to the check
Cells in a dish are a single issue living organisms are another. The researchers up coming analyzed the compound in mice, injecting pure CBD into the guts of the animals each day for 7 days and then spraying stay SARS-CoV-2 into their nasal passages — a surefire route to an infection. They then ongoing the CBD injections for 4 additional days.
5 days right after the viral procedure, the scientists calculated the viral load in the nasal passages and lungs of the mice. They uncovered that with a small dose of CBD, the viral load was 4.8 occasions reduce in the lungs and 3.7 instances lower in the nasal passages in comparison with untreated mice. With a higher dose, the viral load in CBD-addressed mice was 4.8 instances reduce in the nose and a whopping 40 occasions lessen in the lungs than in untreated mice. The contaminated mice also seemed to be fighting off the pathogen with relative simplicity: Lab-contaminated mice ordinarily come to be sick and reduce pounds, but the CBD-addressed mice showed no indications.
CBD is an Fda-authorised treatment method for some seizure ailments, so some folks get common oral doses of the pure compound, Rosner mentioned. She and her group combed by the health care information of people today with seizure disorders, comparing the prices of COVID instances in those using CBD as a treatment to all those with related demographics and health care histories who were not employing CBD, about 530 in each and every group. They located that the amount of COVID-positivity in those actively using CBD was 4.9{fe463f59fb70c5c01486843be1d66c13e664ed3ae921464fa884afebcc0ffe6c}, when compared with 9{fe463f59fb70c5c01486843be1d66c13e664ed3ae921464fa884afebcc0ffe6c} amid all those not getting it.(On the other hand, because it was based on health-related data alone, the study could not rule out that there may be some mysterious differences involving the two groups that may possibly independently have an impact on their hazard of COVID exposure.)
An immune booster?
Past investigation has proven that cannabigerolic acid (CBGA) and cannabidiolic acid (CBDA) could bind to the coronavirus spike protein (illustrated here) and reduce the virus from coming into cells. (Picture credit score: Shutterstock)
With these promising findings in hand, the team then turned to investigating other hashish compounds, these types of as cannabidiolic acid (CBDA), cannabidivarin (CBDV), and THC. They found that CBD alone shown antiviral motion. In truth, combining CBD with THC, as one particular might find in recreational cannabis merchandise, decreased CBD’s antiviral result. In other text, smoking cigarettes or vaping pot will never protect you versus COVID-19, Rosner and her colleagues wrote in their new study, which was released Jan. 20 in the journal Science Improvements. In simple fact, using tobacco or vaping might induce lung harm that can place a person at additional danger if they do capture the disease.
The team also investigated why CBD might be getting an impact. They uncovered that CBD activates a couple of different protective procedures in contaminated cells. One particular, recognized as the “unfolded protein reaction,” is effective on the mobile machinery that gets hijacked by the virus to make more copies of by itself this response allows sustain perform in a cell that is beneath tension. The unfolded protein reaction is so named for the reason that it allows halt the cell’s generation of proteins and crystal clear misfolded or unfolded proteins that are gumming up the works. CBD also served trigger the manufacturing of interferons, immune system compounds that mount a initial-line defense against viral replication inside of the cell.
The SARS-CoV-2 virus has its personal defenses that support it suppress a cell’s interferon manufacturing some early research hints that the omicron variant is fewer critical than earlier variantsfor the reason that it would not suppress its host’s interferon output as considerably. If CBD is able of boosting interferon even as the virus attempts to suppress it, CBD might assistance cut down disease severity.
Related final results have been witnessed in other labs, like Duncan’s. Duncan and her colleagues have analyzed the impact of CBD on unique genes in SARS-CoV-2 infected cells and uncovered benefits that enhance Rosner’s. In that study, which has not yet been peer-reviewed but has been posted onthe preprint databases bioRxiv, Duncan and her staff observed that kidney cells infected with SARS-CoV-2 did a bad job of mounting a frontline antiviral defense. But cells handled with CBD and infected confirmed a marked maximize in genes concerned in antiviral action.
“In general, we each saw comparable points: us, when we ended up seeking at distinct genes and them, when they have been seeking at the total virus,” Duncan reported.
In yet another latest research released in the Journal of All-natural Products, scientists at Oregon State University described that cannabigerolic acid (CBGA) and cannabidiolic acid (CBDA) could bind to the coronavirus spike protein and avert the virus from coming into cells. That is a distinctive mechanism of action than demonstrated in Rosner or Duncan’s analysis, as nicely as distinct hashish compounds. That examine also concentrated exclusively on cells in a petri dish, not in animals or people. It is not but obvious regardless of whether the CBGA or CBDA utilised in that examine could be metabolized correctly to perform in a dwelling organism, Rosner stated. CBD fat burning capacity is far better understood from its use in seizure remedy.
To implement for medical trials in human beings, researchers have to clearly show preclinical info suggesting that a drug may have an effects and must also demonstrate evidence of basic safety. Rosner and her crew have offered that preclinical data, Duncan said, and CBD is already perfectly-recognized to be risk-free and nontoxic in most men and women. The Fda-quality compound is accepted for the cure of seizures in everyone about the age of 1 in the United States.
A examine testing whether or not CBD could reduce an infection would involve a large sample sizing, on the scale of the scientific studies applied to show the efficacy of vaccination, Rosner reported. For that motive, it is a lot more likely that the scientists will initially launch a medical trial screening whether or not CBD could support lower signs or symptoms or severity if taken ideal soon after COVID infection. They hope to go forward with these trials in the in the vicinity of long run.
“We have to have to find a sponsor and we have to have to obtain funding, so we’ve been in dialogue with both equally organizations and our federal government about how to do that most successfully,” Rosner explained.
