Blood Donated from Recovered Coronavirus Patients May Soon Yield a Stopgap Treatment
Antibodies from the blood of recovered patients is being tested as a stopgap treatment.
In October 1918, Lieutenant L.W. McGuire of the United States Navy sent a report to the American Journal of Public Health detailing a promising therapy that had already saved the lives of a number of officers suffering from pneumonia complications due to the Spanish influenza outbreak.
"These antibodies then become essentially drugs."
McGuire described how transfusions of blood from recovered patients – an idea which had first been trialed during a polio epidemic in 1916 – had led to rapid recovery in a series of severe pneumonia cases at a Naval Hospital in Massachusetts. "It is believed the serum has a decided influence in shortening the course of the disease, and lowering the mortality," he wrote.
Now more than a century on, this treatment – long forgotten in the western world - is once again coming to the fore during the current COVID-19 pandemic. With fatalities continuing to rise, and no vaccine expected for many months, experts are urging medical centers across the U.S. and Europe to initiate collaborations between critical care and transfusion services to offer this as an emergency treatment for those who need it most.
As of March 20, there are more than 90,000 individuals globally who have recovered from the disease. Some scientists believe that the blood of many of these people contains high levels of neutralizing antibodies that can kill the virus.
"These antibodies then become essentially drugs," said Arturo Casadevall, professor of Molecular Microbiology & Immunology at John Hopkins Bloomberg School of Public Health, who is currently co-ordinating a clinical trial of convalescent serum for COVID-19 involving 20 institutions across the US.
"We're talking about preparing a therapy right out of the serum of those that have recovered. It could also be used in patients who are already sick, but have not progressed to respiratory failure, to treat them before they enter intensive care units. That will provide a lot of support because there's a limited number of respirators and resources."
The first conclusive data on how the blood of recovered patients can help tackle COVID-19 is set to come out of China, where it was also used as an emergency treatment during the SARS and MERS outbreaks. On February 9, a severely ill patient in Wuhan was treated with convalescent serum and since then, hospitals across China have used the therapy on a total of 245 patients, with 91 reportedly showing an improvement in symptoms.
In China alone, more than 58,000 patients have now recovered from COVID-19. Casadevall said that last week the country shipped 90 tons of serum and plasma from these patients to Italy – the center of the pandemic in Europe – for emergency use.
Some of the first people to be treated are likely to be doctors and nurses in hospitals who are most at risk of exposure.
A current challenge, however, is that the blood donation from the recovered patients must be precisely timed in order to maximize the number of antibodies a future patient receives. Doctors in China say that obtaining the necessary blood samples at the right time is one of the major barriers to applying the treatment on a larger scale.
"It's difficult to get the donations," said Dr. Yuan Shi of Chongqing Medical University. "When patients have recovered from the disease, we would like to collect their blood two to four weeks afterwards. We try our best to call back the patients, but it's sometimes difficult to get them to come back within that time period."
Because of such hurdles, Japan's largest drugmaker, Takeda Pharmaceuticals, is now working to turn neutralizing antibodies from recovered COVID-19 patients into a standardized drug product. They hope to launch a clinical trial for this in the next few months.
In the U.S., Casadevall hopes blood transfusions from recovered patients can become clinically available as a therapy within the next four weeks, once regulatory approval has been received. Some of the first people to be treated are likely to be doctors and nurses in hospitals who are most at risk of exposure, to provide a protective boost in their immunity.
"A lot of healthcare workers in the U.S. have already been asked to quarantine, and you can imagine what effect that's going to have on the healthcare system," he said. "It can't take large numbers of people staying home; there's not the capacity."
But not all medical experts are convinced it's the way to go, especially when it comes to the most severe cases of COVID-19. "There's no knowing whether that treatment would be useful or not," warned Dr. Andrew Freedman, head of Cardiff University's School of Medicine in the U.K.
"There are going to be better things available in a few months, but we are facing, 'What do you do now?'"
However, Casadevall says that the treatment is not envisioned as a panacea to treating coronavirus, but simply a temporary measure which could give doctors some options until stronger options such as vaccines or new drugs are available.
"This is a stopgap option," he said. "There are going to be better things available in a few months, but we are facing, 'What do you do now?' The only thing we can offer severely ill people at the moment is respiratory support and oxygen, and we don't have anything to prevent those exposed from going on and getting ill."

9 Tips for Online Mental Health Therapy
Research shows that, for most patients, online therapy offers the same benefits as in-person therapy, yet many people still resist it. A behavioral scientist explains how you can use it to improve mental health.
Telehealth offers a vast improvement in access and convenience to all sorts of medical services, and online therapy for mental health is one of the most promising case studies for telehealth. With many online therapy options available, you can choose whatever works best for you. Yet many people are hesitant about using online therapy. Even if they do give it a try, they often don’t know how to make the most effective use of this treatment modality.
Why do so many feel uncertain about online therapy? A major reason stems from its novelty. Humans are creatures of habit, prone to falling for what behavioral scientists like myself call the status quo bias, a predisposition to stick to traditional practices and behaviors. Many people reject innovative solutions even when they would be helpful. Thus, while teletherapy was available long before the pandemic, and might have fit the needs of many potential clients, relatively few took advantage of this option.
Even when we do try new methodologies, we often don’t do so effectively, because we cling to the same approaches that worked in previous situations. Scientists call this behavior functional fixedness. It’s kind of like the saying about the hammer-nail syndrome: “when you have a hammer, everything looks like a nail.”
These two mental blindspots, the status quo bias and functional fixedness, impact decision making in many areas of life. Fortunately, recent research has shown effective and pragmatic strategies to defeat these dangerous errors in judgment. The nine tips below will help you make the best decisions to get effective online therapy, based on the latest research.
Trust the science of online therapy
Extensive research shows that, for most patients, online therapy offers the same benefits as in-person therapy.
For instance, a 2014 study in the Journal of Affective Disorders reported that online treatment proved just as effective as face-to-face treatment for depression. A 2018 study, published in Journal of Psychological Disorders, found that online cognitive behavioral therapy, or CBT, was just as effective as face-to-face treatment for major depression, panic disorder, social anxiety disorder, and generalized anxiety disorder. And a 2014 study in Behaviour Research and Therapy discovered that online CBT proved effective in treating anxiety disorders, and helped lower costs of treatment.
During the forced teletherapy of COVID, therapists worried that those with serious mental health conditions would be less likely to convert to teletherapy. Yet research published in Counselling Psychology Quarterly has helped to alleviate that concern. It found that those with schizophrenia, bipolar disorder, severe depression, PTSD, and even suicidality converted to teletherapy at about the same rate as those with less severe mental health challenges.
Yet teletherapy may not be for everyone. For example, adolescents had the most varied response to teletherapy, according to a 2020 study in Family Process. Some adapted quickly and easily, while others found it awkward and anxiety-inducing. On the whole, children with trauma respond worse to online therapy, per a 2020 study in Child Abuse & Neglect. The treatment of mental health issues can sometimes require in-person interactions, such as the use of eye movement desensitization and reprocessing to treat post-traumatic stress disorder. And according to a 2020 study from the Journal of Humanistic Psychology, online therapy may not be as effective for those suffering from loneliness.
Leverage the strengths of online therapy
Online therapy is much more accessible than in-person therapy for those with a decent internet connection, webcam, mic, and digital skills. You don’t have to commute to your therapist’s office, wasting money and time. You can take much less medical leave from work, saving you money and hassle with your boss. If you live in a sparsely populated area, online therapy could allow you to access many specialized kinds of therapy that isn’t accessible locally.
Online options are much quicker compared to the long waiting lines for in-person therapy. You also have much more convenient scheduling options. And you won’t have to worry about running into someone you know in the waiting room. Online therapy is easier to conceal from others and reduces stigma. Many patients may feel more comfortable and open to sharing in the privacy and comfort of their own home.
You can use a variety of communication tools suited to your needs at any given time. Video can be used to start a relationship with a therapist and have more intense and nuanced discussions, but can be draining, especially for those with social anxiety. Voice-only may work well for less intense discussions. Email offers a useful option for long-form, well-thought-out messages. Texting is useful for quick, real-time questions, answers, and reinforcement.
Plus, online therapy is often cheaper than in-person therapy. In the midst of COVID, many insurance providers have decided to cover online therapy.
Address the weaknesses
One weakness is the requirement for appropriate technology and skills to engage in online therapy. Another is the difficulty of forming a close therapeutic relationship with your therapist. You won’t be able to communicate non-verbals as fully and the therapist will not be able to read you as well, requiring you to be more deliberate in how you express yourself.
Another important issue is that online therapy is subject to less government oversight compared to the in-person approach, which is regulated in each state, providing a baseline of quality control. As a result, you have to do more research on the providers that offer online therapy to make sure they’re reputable, use only licensed therapists, and have a clear and transparent pay structure.
Be intentional about advocating for yourself
Figure out what kind of goals you want to achieve. Consider how, within the context of your goals, you can leverage the benefits of online therapy while addressing the weaknesses. Write down and commit to achieving your goals. Remember, you need to be your own advocate, especially in the less regulated space of online therapy, so focus on being proactive in achieving your goals.
Develop your Hero’s Journey
Because online therapy can occur at various times of day through videos calls, emails and text, it might feel more open-ended and less organized, which can have advantages and disadvantages. One way you can give it more structure is to ground these interactions in the story of your self-improvement. Our minds perceive the world through narratives. Create a story of how you’ll get from where you are to where you want to go, meaning your goals.
A good template to use is the Hero’s Journey. Start the narrative with where you are, and what caused you to seek therapy. Write about the obstacles you will need to overcome, and the kind of help from a therapist that you’ll need in the process. Then, describe the final end state: how will you be better off after this journey, including what you will have learned.
Especially in online therapy, you need to be on top of things. Too many people let the therapist manage the treatment plan. As you pursue your hero’s journey, another way to organize for success is to take notes on your progress, and reevaluate how you’re doing every month with your therapist.
Identify your ideal mentor
Since it’s more difficult to be confident about the quality of service providers in an online setting, you should identify in advance the traits of your desired therapist. Every Hero’s Journey involves a mentor figure who guides the protagonist through this journey. So who’s your ideal mentor? Write out their top 10 characteristics, from most to least important.
For example, you might want someone who is:
- Empathetic
- Caring
- Good listener
- Logical
- Direct
- Questioning
- Non-judgmental
- Organized
- Curious
- Flexible
That’s my list. Depending on what challenge you’re facing and your personality and preferences, you should make your own. Then, when you are matched with a therapist, evaluate how well they fit your ideal list.
Fail fast
When you first match with a therapist, try to fail fast. That means, instead of focusing on getting treatment, focus on figuring out if the therapist is a good match based on the traits you identified above. That will enable you to move on quickly if they’re not, and it’s very much worth it to figure that out early.
Tell them your goals, your story, and your vision of your ideal mentor. Ask them whether they think they are a match, and what kind of a treatment plan they would suggest based on the information you provided. And observe them yourself in your initial interactions, focusing on whether they’re a good match. Often, you’ll find that your initial vision of your ideal mentor is incomplete, and you’ll learn through doing therapy what kind of a therapist is the best fit for you.
Choose a small but meaningful subgoal to work on first
This small subgoal should be sufficient to be meaningful and impactful for improving your mental health, but not a big stretch for you to achieve. This subgoal should be a tool for you to use to evaluate whether the therapist is indeed a good fit for you. It will also help you evaluate whether the treatment plan makes sense, or whether it needs to be revised.
Know when to wrap things up
As you approach the end of your planned work and you see you’re reaching your goals, talk to the therapist about how to wrap up rather than letting things drag on for too long. You don’t want to become dependent on therapy: it’s meant to be a temporary intervention. Some less scrupulous therapists will insist that therapy should never end and we should all stay in therapy forever, and you want to avoid falling for this line. When you reach your goals, end your therapy, unless you discover a serious new reason to continue it. Still, it may be wise to set up occasional check-ins once every three to six months to make sure you’re staying on the right track.
