After a Diagnosis, Patients Are Finding Solace—and Empowerment—in a Sensitive Corner of Social Media
Katherine Leon and her dog enjoy nice weather in their backyard in Virginia. Leon went from feeling like she was "wandering in the woods" with doctors who hadn't experienced her spontaneous coronary artery dissection, or SCAD, to starting the world's largest registry for research on the condition.
When Kimberly Richardson of Chicago underwent chemotherapy in 2013 for ovarian cancer, her hip began to hurt. Her doctor assigned six months of physical therapy, but the pain persisted.
She took the mystery to Facebook, where she got 200 comments from cancer survivors all pointing to the same solution: Claritin. Two days after starting the antihistamine, her hip felt fine. Claritin, it turns out, reduces bone marrow swelling, a side effect of a stimulant given after chemo.
Richardson isn't alone in using social media for health. Thirty-six percent of adults with chronic diseases have benefited from health advice on the internet, or know others who have. The trend has likely accelerated during COVID-19. "With increases in anxiety and loneliness, patients find comfort in peer support," said Chris Renfro-Wallace, the chief operating officer of PatientsLikeMe, a popular online community.
Sites like PatientsLikeMe and several others are giving rise to a patient-centered view of healthcare, challenging the idea that MD stands for medical deity. They're engaging people in new ways, such as virtual clinical trials. But with misinformation spreading online about health issues, including COVID-19, there's also reason for caution.
Engaged by Design
Following her diagnosis at age 50, Richardson searched the Web. "All I saw were infographics saying in five years I'd be dead."
Eventually, she found her Facebook groups and a site called Inspire, where she met others with her rare granulosa cell tumor. "You get 15 minutes with your doctor, but on social media you can keep posting until you satisfy your question."
Virtual communities may be especially helpful for people with rarely diagnosed diseases, who wouldn't otherwise meet. When Katherine Leon of Virginia suffered chest pain after the birth of her second son, doctors said it was spontaneous coronary artery dissection, or SCAD, involving a torn artery. But she had no risk factors for heart disease. Feeling like she was "wandering in the woods" with doctors who hadn't experienced her situation, she searched online and stumbled on communities like Inspire with members who had. The experience led her to start her own Alliance and the world's largest registry for advancing research on SCAD.
"Inspire is really an extension of yourself," she said. If designed well, online sites can foster what psychologist Keith Sawyer called group mind, a dynamic where participants balance their own voices with listening to others, maximizing community engagement in health. To achieve it, participants must have what Sawyer called a "blending of egos," which may be fostered when sites let users post anonymously. They must also share goals and open communication. The latter priority has driven Brian Loew, Inspire's CEO, to safeguard the privacy of health information exchanged on the site, often asking himself, "Would I be okay if a family member had this experience?"
The vibe isn't so familial on some of Facebook's health-focused groups. There, people might sense marketers and insurers peering over their shoulders. In 2018, a researcher discovered that companies could exploit personal information on a private Facebook community for BRCA-positive women. Members of the group started a nonprofit, the Light Collective, to help peer-to-peer support platforms improve their transparency.
PatientsLikeMe and Inspire nurture the shared experience by hosting pages on scores of diseases, allowing people to better understand treatment options for multiple conditions—and find others facing the same set of issues. Four in ten American adults have more than one chronic disease.
Sawyer observed that groups are further engaged when there's a baseline of common knowledge. To that end, some platforms take care in structuring dialogues among members to promote high-quality information, stepping in to moderate when necessary. On Inspire, members get emails when others reply to their posts, instead of instant messaging. The communication lag allows staff to notice misinformation and correct it. Facebook conversations occur in real-time among many more people; "moderation is almost impossible," said Leon.
Even on PatientsLikeMe and Inspire, deciding which content to police can be tough, as variations across individuals may result in conflicting but equally valid posts. Leon's left main artery was 90 percent blocked, requiring open heart surgery, whereas others with SCAD have angina, warranting a different approach. "It's a real range of experience," she explained. "That's probably the biggest challenge: supporting everyone where they are."
Critically, these sites don't treat illnesses. "If a member asks a medical question, we typically tell them to go to their doctor," said Loew, the Inspire CEO.
Increasingly, it may be the other way around.
The Patient Will See You Now
"Some doctors embrace the idea of an educated patient," said Loew. "The more information, the better." Others, he said, aren't thrilled about patients learning on their own.
"Doctors were behind the eight ball," said Shikha Jain, an oncologist in Chicago. "We were encouraged for years to avoid social media due to patient privacy issues. There's been a drastic shift in the last few years."
Jain recently co-founded IMPACT, a grassroots organization that networks with healthcare workers across Illinois for greater awareness of health issues. She thinks doctors must meet patients where they are—increasingly, online—and learn about the various platforms where patients connect. Doctors can then suggest credible online sources for their patients' conditions. Learning about different sites takes time, Jain said, "but that's the nature of being a physician in this day and age."
At stake is the efficiency of doctor-patient interactions. "I like when patients bring in research," Jain said. "It opens up the dialogue and lets them inform the decision-making process." Richardson, the cancer survivor, agreed. "We shouldn't make the physician the villain in this conversation." Interviewed over Zoom, she was engaging but quick to challenge the assumptions behind some questions; her toughness was palpable, molded by years of fighting disease—and the healthcare system. Many doctors are forced by that system into faster office visits, she said. "If patients help their doctor get to the heart of the issue in a shorter time, now we're going down a narrower road of tests."
These conversations could be enhanced by PatientsLikeMe's Doctor Visit Guide. It uses algorithms to consolidate health data that members track on the site into a short report they can share with their physicians. "It gives the doctor a richer data set to really see how a person has been doing," said Renfro-Wallace.
Doctors aren't the only ones benefiting from these sites.
Who Profits?
A few platforms like Inspire make money by connecting their members to drug companies, so they can participate in the companies' clinical trials to test out new therapies. A cynic might say the sites are just fronts for promoting the pharmaceuticals.
The need is real, though, as many clinical trials suffer from low participation, and the experimental treatments can improve health. The key for Loew, Inspire's CEO, is being transparent about his revenue model. "When you sign up, we assume you didn't read the fine print [in the terms of agreement]." So, when Inspire tells members about openings in trials, it's a reminder the site works with pharma.
"When I was first on Inspire, all of that was invisible to me," said Leon. "It didn't dawn on me for years." Richardson believes many don't notice pharma's involvement because they're preoccupied by their medical issues.
One way Inspire builds trust is by partnering with patient advocacy groups, which tend to be nonprofit and science-oriented, said Craig Lipset, the former head of clinical innovation for Pfizer. When he developed a rare lung disease, he joined the board of a foundation that partners with Inspire's platform. The section dedicated to his disease is emblazoned with his foundation's logo and colors. Contrast that with other sites that build communities at the direct behest of drug companies, he said.
Insurance companies are also eyeing these communities. Last month, PatientsLikeMe raised $26 million in financing from investors including Optum Ventures, which belongs to the same health care company that owns a leading health insurance company, UnitedHealthcare. PatientsLikeMe is an independent company, though, and data is shared with UnitedHealth only if patients provide consent. The site is using the influx of resources to gamify improvements in health, resembling programs run by UnitedHealth that assign nutrition and fitness "missions," with apps for tracking progress. Soon, PatientsLikeMe will roll out a smarter data tracking system that gives members actionable insights and prompts them to take actions based on their conditions, as well as competitions to motivate healthier behaviors.
Such as a race to vaccinate, perhaps.
Dealing with Misinformation
An advantage of health-focused communities is the intimacy of their gatherings, compared to behemoths like Facebook. Loew, Inspire's head, is mindful of Dunbar's rule: humans can manage only about 150 friends. Inspire's social network mapping suggests many connections among members, but of different strength; Loew hopes to keep his site's familial ambiance even while expanding membership. Renfro-Wallace is exploring video and voice-only meetings to enrich the shared experiences on PatientsLikeMe, while respecting members' privacy.
But a main driver of growth and engagement online is appealing to emotion rather than reason; witness Facebook during the pandemic. "We know that misinformation and scary things spread far more rapidly than something positive," said Ann Lewandowski, the executive director of Wisconsin Immunization Neighborhood, a coalition of health providers and associations countering vaccine hesitancy across the state.
"Facebook's moderation mechanism is terrible," she said. Vaccine advocates in her region who try to flag misinformation on Facebook often have their content removed because the site's algorithm associates their posts with the distortions they're trying to warn people about.
In the realm of health, where accessing facts can mean life or death—and where ad-based revenue models conflict with privacy needs—there's probably a ceiling on how large social media sites should scale. Loew views Inspire as co-existing, not competing with Facebook.
Propagandists had months to perfect campaigns to dissuade people from mRNA vaccines. But even Lewandowski's doctor was misinformed about vaccine side effects for her condition, multiple sclerosis. She sees potential for health-focused sites to convene more virtual forums, in which patient advocacy groups educate doctors and patients on vaccine safety.
Inspire is raising awareness about COVID vaccines through a member survey with an interactive data visualization. Sampling thousands of members, the survey found vaccines are tolerated well among patients with cancer, autoimmune issues, and other serious conditions. Analytics for online groups are evolving quickly, said Lipset. "Think about the acceleration in research when you take the emerging capability for aggregating health data and mash it up with patients engaged in sharing."
Lipset recently co-founded the Decentralized Trials and Research Alliance to accelerate clinical trials and make them more accessible to patients—even from home, without risking the virus. Sites like PatientsLikeMe share this commitment, collaborating with Duke's ALS Clinic to let patients join a trial from home with just two clinic visits. Synthetic control groups were created by PatientsLikeMe's algorithms, eliminating the need for a placebo arm, enabling faster results.
As for Richardson, the ovarian cancer patient, being online has given her another type of access—to experts. She was diagnosed this year with breast cancer. "This time is totally different," she said. On Twitter, she's been direct messaging cancer researchers, whose replies have informed her disease-management strategy. When her oncologists prescribed 33 radiation treatments, she counter-proposed upping the dosage over fewer treatments. Her doctors agreed, cutting unnecessary trips from home. "I'm immuno-compromised," she said. "It's like Russian roulette. You're crossing your finger you won't get the virus."
After years of sticking up for her own health, Richardson is now positioned to look out for others. She collaborated with the University of Illinois Cancer Center on a training module that lets patients take control of their health. She's sharing it online, in a virtual community near you. "It helps you make intelligent decisions," she said. "When you speak your physician's language, it shifts the power in the room."
Scientists search for a universal coronavirus vaccine
Stephen Zeichner, an infectious disease specialist at the University of Virginia Medical Center, has made progress with an early stage universal coronavirus vaccine.
The Covid-19 pandemic had barely begun when VBI Vaccines, a biopharmaceutical company based in Cambridge, Massachusetts, initiated their search for a universal coronavirus vaccine.
It was March 2020, and while most pharmaceutical companies were scrambling to initiate vaccine programs which specifically targeted the SARS-CoV-2 virus, VBI’s executives were already keen to look at the broader picture.
Having observed the SARS and MERS coronavirus outbreaks over the last two decades, Jeff Baxter, CEO of VBI Vaccines, was aware that SARS-CoV-2 is unlikely to be the last coronavirus to move from an animal host into humans. “It's absolutely apparent that the future is to create a vaccine which gives more broad protection against not only pre-existing coronaviruses, but those that will potentially make the leap into humans in future,” says Baxter.
It was a prescient decision. Over the last two years, more biotechs and pharma companies have joined the search to find a vaccine which might be able to protect against all coronaviruses, along with dozens of academic research groups. Last September, the US National Institutes of Health dedicated $36 million specifically to pan-coronavirus vaccine research, while the global Coalition for Epidemic Preparedness Innovations (CEPI) has earmarked $200 million towards the effort.
Until October 2021, the very concept of whether it might be
theoretically possible to vaccinate against multiple coronaviruses remained an open question. But then a groundbreaking study renewed optimism.
The emergence of new variants of Covid-19 over the past year, particularly the highly mutated Omicron variant, has added greater impetus to find broader spectrum vaccines. But until October 2021, the very concept of whether it might be theoretically possible to vaccinate against multiple coronaviruses remained an open question. After all, scientists have spent decades trying to develop a similar vaccine for influenza with little success.
But then a groundbreaking study from renowned virologist Linfa Wang, who runs the emerging infectious diseases program at Duke-National University of Singapore Medical School, provided renewed optimism.
Wang found that eight SARS survivors who had been injected with the Pfizer/BioNTech Covid-19 vaccine had neutralising antibodies in their blood against SARS, the Alpha, Beta and Delta variants of SARS-CoV-2, and five other coronaviruses which reside in bats and pangolins. He concluded that the combination of past coronavirus infection, and immunization with a messenger RNA vaccine, had resulted in a wider spectrum of protection than might have been expected.
“This is a significant study because it showed that pre-existing immunity to one coronavirus could help with the elicitation of cross-reactive antibodies when immunizing with a second coronavirus,” says Kevin Saunders, Director of Research at the Duke Human Vaccine Institute in North Carolina, which is developing a universal coronavirus vaccine. “It provides a strategy to perhaps broaden the immune response against coronaviruses.”
In the next few months, some of the first data is set to emerge looking at whether this kind of antibody response could be elicited by a single universal coronavirus vaccine. In April 2021, scientists at the Walter Reed Army Institute of Research in Silver Spring, Maryland, launched a Phase I clinical trial of their vaccine, with a spokesman saying that it was successful, and the full results will be announced soon.
The Walter Reed researchers have already released preclinical data, testing the vaccine in non-human primates where it was found to have immunising capabilities against a range of Covid-19 variants as well as the original SARS virus. If the Phase I trial displays similar efficacy, a larger Phase II trial will begin later this year.
Two different approaches
Broadly speaking, scientists are taking two contrasting approaches to the task of finding a universal coronavirus vaccine. The Walter Reed Army Institute of Research, VBI Vaccines – who plan to launch their own clinical trial in the summer – and the Duke Human Vaccine Institute – who are launching a Phase I trial in early 2023 – are using a soccer-ball shaped ferritin nanoparticle studded with different coronavirus protein fragments.
VBI Vaccines is looking to elicit broader immune responses by combining SARS, SARS-CoV-2 and MERS spike proteins on the same nanoparticle. Dave Anderson, chief scientific officer at VBI Vaccines, explains that the idea is that by showing the immune system these three spike proteins at the same time, it can help train it to identify and respond to subtle differences between coronavirus strains.
The Duke Human Vaccine Institute is utilising the same method, but rather than including the entire spike proteins from different coronaviruses, they are only including the receptor binding domain (RBD) fragment from each spike protein. “We designed our vaccine to focus the immune system on a site of vulnerability for the virus, which is the receptor binding domain,” says Saunders. “Since the RBD is small, arraying multiple RBDs on a nanoparticle is a straight-forward approach. The goal is to generate immunity to many different subgenuses of viruses so that there will be cross-reactivity with new or unknown coronaviruses.”
But the other strategy is to create a vaccine which contains regions of the viral protein structure which are conserved between all coronavirus strains. This is something which scientists have tried to do for a universal influenza vaccine, but it is thought to be more feasible for coronaviruses because they mutate at a slower rate and are more constrained in the ways that they can evolve.
DIOSynVax, a biotech based in Cambridge, United Kingdom, announced in a press release earlier this month that they are partnering with CEPI to use their computational predictive modelling techniques to identify common structures between all of the SARS coronaviruses which do not mutate, and thus present good vaccine targets.
Stephen Zeichner, an infectious disease specialist at the University of Virginia Medical Center, has created an early stage vaccine using the fusion peptide region – another part of the coronavirus spike protein that aids the virus’s entry into host cells – which so far appears to be highly conserved between all coronaviruses.
So far Zeichner has trialled this version of the vaccine in pigs, where it provided protection against a different coronavirus called porcine epidemic diarrhea virus, which he described as very promising as this virus is from a different family called alphacoronaviruses, while SARS-CoV-2 is a betacoronavirus.
“If a betacoronavirus fusion peptide vaccine designed from SARS-CoV-2 can protect pigs against clinical disease from an alphacoronavirus, then that suggests that an analogous vaccine would enable broad protection against many, many different coronaviruses,” he says.
The road ahead
But while some of the early stage results are promising, researchers are fully aware of the scale of the challenge ahead of them. Although CEPI have declared an aim of having a licensed universal coronavirus vaccine available by 2024-2025, Zeichner says that such timelines are ambitious in the extreme.
“I was incredibly impressed at the speed at which the mRNA coronavirus vaccines were developed for SARS-CoV-2,” he says. “That was faster than just about anybody anticipated. On the other hand, I think a universal coronavirus vaccine is more equivalent to the challenge of developing an HIV vaccine and we're 35 years into that effort without success. We know a lot more now than before, and maybe it will be easier than we think. But I think the route to a universal vaccine is harder than an individual vaccine, so I wouldn’t want to put money on a timeline prediction.”
The major challenge for scientists is essentially designing a vaccine for a future threat which is not even here yet. As such, there are no guidelines on what safety data would be required to license such a vaccine, and how researchers can demonstrate that it truly provides efficacy against all coronaviruses, even those which have not yet jumped to humans.
The teams working on this problem have already devised some ingenious ways of approaching the challenge. VBI Vaccines have taken the genetic sequences of different coronaviruses found in bats and pangolins, from publicly available databases, and inserted them into what virologists call a pseudotype virus – one which has been engineered so it does not have enough genetic material to replicate.
This has allowed them to test the neutralising antibodies that their vaccine produces against these coronaviruses in test tubes, under safe lab conditions. “We have literally just been ordering the sequences, and making synthetic viruses that we can use to test the antibody responses,” says Anderson.
However, some scientists feel that going straight to a universal coronavirus vaccine is likely to be too complex. Instead they say that we should aim for vaccines which are a little more specific. Pamela Bjorkman, a structural biologist at the California Institute of Technology, suggests that pan-coronavirus vaccines which protect against SARS-like betacoronaviruses such as SARS or SARS-CoV-2, or MERS-like betacoronaviruses, may be more realistic.
“I think a vaccine to protect against all coronaviruses is likely impossible since there are so many varieties,” she says. “Perhaps trying to narrow down the scope is advisable.”
But if the mission to develop a universal coronavirus vaccine does succeed, it will be one of the most remarkable feats in the annals of medical science. In January, US chief medical advisor Anthony Fauci urged for greater efforts to be devoted towards this goal, one which scientists feel would be the biological equivalent of the race to develop the first atomic bomb
“The development of an effective universal coronavirus vaccine would be equally groundbreaking, as it would have global applicability and utility,” says Saunders. “Coronaviruses have caused multiple deadly outbreaks, and it is likely that another outbreak will occur. Having a vaccine that prevents death from a future outbreak would be a tremendous achievement in global health.”
He agrees that it will require creativity on a remarkable scale: “The universal coronavirus vaccine will also require ingenuity and perseverance comparable to that needed for the Manhattan project.”
This month, Matt Fuchs becomes the new Editor-in-Chief of Leaps.org.
This month, Kira Peikoff passes the torch to me as editor-in-chief of Leaps.org. I’m excited to assume leadership of this important platform.
Leaps.org caught my eye back in 2018. I was in my late 30s and just starting to wake up to the reality that the people I care most about were getting older and more vulnerable to health problems. At the same time, three critical shifts were becoming impossible to ignore. First, the average age in the U.S. is getting older, a trend known as the “gray tsunami.” Second, healthcare expenses are escalating and becoming unsustainable. And third, our sedentary, stress-filled lifestyles are leading to devastating consequences.
These trends pointed to a future filled with disease, suffering and economic collapse. But whenever I visited Leaps.org, my outlook turned from gloomy to solution-oriented. I became just as fascinated in a fourth trend, one that stands to revolutionize our world: rapid, mind-bending innovations in health and medicine.
Brain atlases, genome sequencing and editing, AI, protein mapping, synthetic biology, 3-D printing—these technologies are yielding new opportunities for health, longevity and human thriving. COVID-19 has caused many setbacks, but it has accelerated scientific breakthroughs. History suggests we will see even more innovation—in digital health and virtual first care, for example—after the pandemic.
In 2020, I began covering these developments with articles for Leaps.org about clocks that measure biological aging, gene therapies for cystic fibrosis, and other seemingly futuristic concepts that are transforming the present. I wrote about them partly because I think most people aren’t aware of them—and meaningful progress can’t happen without public engagement. A broader set of stakeholders and society at large, not just the experts, must inform these changes to ensure that they reflect our values and ethics. Everyone should get the chance to participate in the conversation—and they must have the opportunity to benefit equally from the innovations we decide to move forward with. By highlighting cutting-edge advances, Leaps.org is helping to realize this important goal.
Meanwhile, as I wrote freelance pieces on health and wellness for outlets such as the Washington Post and Time Magazine, I kept seeing an intersect between the breakthroughs in research labs and our expanding knowledge about the science of well-being. Take, for example, emerging technologies designed to stop illnesses in their tracks and new research on the benefits of taking in natural daylight. These two areas, lab innovations and healthy lifestyles, both shift the focus from disease treatment to disease prevention and optimal health. It’s the only sensible, financially feasible way forward.
When Kira suggested that I consider a leadership role with Leaps.org, it struck me how much the platform’s ideals have informed my own perspectives. The frontpage gore of mainstream media outlets can feel like a daily dose of pessimism, with cynicism sometimes dressed up as wisdom. Leaps.org’s world view is rooted in something very different: rational optimism about the present moment and the possibility of human flourishing.
That’s why I’m proud to lead this platform, including our podcast, Making Sense of Science, and hope you’ll keep coming to Leaps.org to learn and join the conversation about scientific gamechangers through our sponsored events, our popular Instagram account and other social channels. Think critically about the breakthroughs and their ethical challenges. Help usher in the health and prosperity that could be ours if we stay open-minded to it.
Yours truly,
Matt Fuchs
