Erica Hayes, 40, has not felt healthy since November 2020 when she first fell ill with covid.
Hayes is too sick to work, so she has spent much of the last four years sitting on her beige couch, often curled up under an electric blanket.
鈥淢y blood flow now sucks, so my hands and my feet are freezing. Even if I鈥檓 sweating, my toes are cold,鈥� , who lives in Western Pennsylvania. She misses feeling well enough to play with her 9-year-old son or attend her 17-year-old son鈥檚 baseball games.
Along with claiming the lives of 1.2 million Americans, the covid-19 pandemic has been described as a . Hayes is one of millions of Americans who suffer from long covid. Depending on the patient, the condition can rob someone of energy, scramble the autonomic nervous system, or fog their memory, among many other symptoms.
In addition to the brain fog and chronic fatigue, Hayes鈥� constellation of symptoms includes frequent hives and migraines. Also, her tongue is constantly swollen and dry.
鈥淚鈥檝e had multiple doctors look at it and tell me they don鈥檛 know what鈥檚 going on,鈥� Hayes said about her tongue.聽
Estimates of prevalence range considerably, depending on how researchers define long covid in a given study, but the Centers for Disease Control and Prevention puts it at 17 million adults.
Despite long covid鈥檚 vast reach, the federal government鈥檚 investment in researching the disease 鈥� to the tune of $1.15 billion as of December 鈥� has so far failed to bring any new treatments to market.聽
This disappoints and angers the patient community, who say the National Institutes of Health should focus on ways to stop their suffering instead of simply trying to understand why they鈥檙e suffering.
鈥淚t鈥檚 unconscionable that more than four years since this began, we still don鈥檛 have one FDA-approved drug,鈥� said , executive director of the , a patient-led advocacy organization. Stone was among several people with long covid who spoke at a workshop hosted by the NIH in September where patients, clinicians, and researchers discussed their priorities and frustrations around the agency鈥檚 approach to long-covid research.
Some doctors and researchers are also critical of the agency鈥檚 research initiative, called RECOVER, or Researching COVID to Enhance Recovery. Without clinical trials, physicians specializing in treating long covid must rely on hunches to guide their clinical decisions, said , chief of research and development with the .
鈥淲hat [RECOVER] lacks, really, is clarity of vision and clarity of purpose,鈥� said Al-Aly, saying he agrees that the NIH has had enough time and money to produce more meaningful progress.
Now the NIH is starting to determine how to allocate an additional of funding for long-covid research, of which is earmarked for clinical trials. These funds will be allocated over the next four years.
At the end of October, RECOVER for clinical trial ideas that look at potential therapies, including medications, saying its goal is 鈥渢o work rapidly, collaboratively, and transparently to advance treatments for Long COVID.鈥�
This turn suggests the NIH has begun to respond to patients. This has stirred cautious optimism among those who say that the agency鈥檚 approach to long covid has lacked urgency in the search for effective treatments.
Stone calls this $300 million a down payment. She warns it鈥檚 going to take a lot more money to help people like Hayes regain some degree of health.
鈥淭here really is a burden to make up this lost time now,鈥� Stone said.
The NIH told 黑料吃瓜网 News and NPR via email that it recognizes the urgency in finding treatments. But to do that, there needs to be an understanding of the biological mechanisms that are making people sick, which is difficult to do with post-infectious conditions.
That鈥檚 why it has funded research into how long covid affects , or trying to understand why people are afflicted with the condition.
Good Science Takes Time
In December 2020, for the NIH to launch RECOVER, raising hopes in the long-covid patient community.
Then-NIH Director explained that was to better understand long covid as a disease and that clinical trials of potential treatments would come later.
According to 搁贰颁翱痴贰搁鈥檚 website, it has funded to test the safety and effectiveness of an experimental treatment or intervention. Just one of those trials has .
On the other hand, RECOVER has supported more than 200 observational studies, such as research on how long covid and on which symptoms are . And the initiative has funded more than 40 pathobiology studies, which focus on the basic cellular and molecular mechanisms of long covid.
搁贰颁翱痴贰搁鈥檚 this research has led to crucial insights on the risk factors for developing long covid and on understanding how the disease interacts with preexisting conditions.
It notes that observational studies are important in helping scientists to design and launch evidence-based clinical trials.
Good science takes time, said , the co-principal investigator for the RECOVER-Adult Observational Cohort at New York University. And long covid is an 鈥渆xceedingly complicated鈥� illness that appears to affect nearly every organ system, she said.聽
This makes it more difficult to study than many other diseases. Because long covid harms the body in so many ways, with widely variable symptoms, it鈥檚 harder to identify precise targets for treatment.
鈥淚 also will remind you that we鈥檙e only three, four years into this pandemic for most people,鈥� Horwitz said. 鈥淲e鈥檝e been spending much more money than this, yearly, for 30, 40 years on other conditions.鈥�
NYU received of RECOVER funds in 2021, which the institution is using to spearhead the collection of data and biospecimens from up to 40,000 patients. Horwitz said nearly 30,000 are enrolled so far.
This , Horwitz said, supports ongoing observational research, allowing scientists to understand what is happening biologically to people who don鈥檛 recover after an initial infection 鈥� and that will help determine which clinical trials for treatments are worth undertaking.
鈥淪imply trying treatments because they are available without any evidence about whether or why they may be effective reduces the likelihood of successful trials and may put patients at risk of harm,鈥� she said.
Delayed Hopes or Incremental Progress?
The NIH told 黑料吃瓜网 News and NPR that patients and caregivers have been central to RECOVER from the beginning, 鈥減laying critical roles in designing studies and clinical trials, responding to surveys, serving on governance and publication groups, and guiding the initiative.鈥�
But the consensus from patient advocacy groups is that RECOVER should have done more to prioritize clinical trials from the outset. Patients also say RECOVER leadership ignored their priorities and experiences when determining which studies to fund.
RECOVER has scored some gains, said , co-director of . This includes findings on differences in long covid between adults and kids.
But Davids said the NIH shouldn鈥檛 have named the initiative 鈥淩ECOVER,鈥� since it wasn鈥檛 designed as a streamlined effort to develop treatments.
鈥淭he name鈥檚 a little cruel and misleading,鈥� he said.
搁贰颁翱痴贰搁鈥檚 initial allocation of $1.15 billion probably wasn鈥檛 enough to develop a new medication to treat long covid, said co-director of the University of Pennsylvania鈥檚 .
But, he said,聽 the results of preliminary clinical trials could have spurred pharmaceutical companies to fund more studies on drug development and test how existing drugs influence a patient鈥檚 immune response.
Emanuel is one of the authors of a March 2022 covid . He notes that 搁贰颁翱痴贰搁鈥檚 lack of focus on new treatments was a problem. 鈥淥nly 15% of the budget is for clinical studies. That is a failure in itself 鈥� a failure of having the right priorities,鈥� he told 黑料吃瓜网 News and NPR via email.
And though the NYU biobank has been impactful, Emanuel said there needs to be more focus on how existing drugs influence immune response.
He said some clinical trials that RECOVER has funded are 鈥渞idiculous,鈥� because they鈥檝e focused on symptom amelioration, for example to of over-the-counter medication to improve sleep. Other studies looked at non-pharmacological interventions, such as exercise and 鈥溾�� to help with cognitive fog.
People with long covid say this type of clinical research contributes to what many describe as the 鈥済aslighting鈥� they experience from doctors, who sometimes blame a patient鈥檚 symptoms on anxiety or depression, rather than acknowledging long covid as a real illness with a physiological basis.
鈥淚鈥檓 just disgusted,鈥� said long-covid patient Hayes. 鈥淵ou wouldn鈥檛 tell somebody with diabetes to breathe through it.鈥�
, director and founder of the , said she鈥檚 even taken breaks from seeking treatment after getting fed up with being told that her symptoms were due to her diet or mental health.
鈥淵ou鈥檙e at the whim of somebody who may not even understand the spectrum of long covid,鈥� Sweeney said.
Insurance Battles Over Experimental Treatments
Since there are still no long-covid treatments approved by the Food and Drug Administration, anything a physician prescribes is classified as either experimental 鈥� for unproven treatments 鈥� or an off-label use of a drug approved for other conditions. This means patients can struggle to get insurance to cover prescriptions.
, medical director for 鈥� said he writes many appeal letters. And some people pay for their own treatment.
For example, intravenous immunoglobulin therapy, low-dose naltrexone, and hyperbaric oxygen therapy are all promising treatments, he said.
For hyperbaric oxygen, , randomized show improvements for the chronic fatigue and brain fog that often plague long-covid patients. The theory is that higher oxygen concentration and increased air pressure can help heal tissues that were damaged during a covid infection.
However, the out-of-pocket cost for a series of sessions in a hyperbaric chamber can run as much as $8,000, Brode said.
鈥淎m I going to look a patient in the eye and say, 鈥榊ou need to spend that money for an unproven treatment鈥�?鈥� he said. 鈥淚 don鈥檛 want to hype up a treatment that is still experimental. But I also don鈥檛 want to hide it.鈥�
There鈥檚 a host of pharmaceuticals that have promising off-label uses for long covid, said microbiologist , president and chief scientific officer at the Massachusetts-based . For instance, she鈥檚 collaborating on a clinical study that repurposes two HIV drugs to treat long covid.
Proal said research on treatments can move forward based on what鈥檚 already understood about the disease. For instance, she said that scientists 鈥� partly due to 鈥� that some patients small amounts of viral material after a covid infection. She has not received RECOVER funds but is researching antivirals.
But to vet a range of possible treatments for the millions suffering now 鈥� and to develop new drugs specifically targeting long covid 鈥� clinical trials are needed. And that requires money.
Hayes said she would definitely volunteer for an experimental drug trial. For now, though, 鈥渋n order to not be absolutely miserable,鈥� she said she focuses on what she can do, like having dinner with her family.
At the same time, Hayes doesn鈥檛 want to spend the rest of her life on a beige couch.聽
搁贰颁翱痴贰搁鈥檚 deadline to submit research proposals for potential long-covid treatments is Feb. 1.
