Disruptions in cancer care in the era of COVID-19
Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center.
Even in the midst of the COVID-19 pandemic, cancer care must go on, but changes may need to be made in the way some care is delivered.
“We’re headed for a time when there will be significant disruptions in the care of patients with cancer,” said Len Lichtenfeld, MD, deputy chief medical officer of the American Cancer Society (ACS), in a statement. “For some it may be as straightforward as a delay in having elective surgery. For others it may be delaying preventive care or adjuvant chemotherapy that’s meant to keep cancer from returning or rescheduling appointments.”
Lichtenfeld emphasized that cancer care teams are going to do the best they can to deliver care to those most in need. However, even in those circumstances, it won’t be life as usual. “It will require patience on everyone’s part as we go through this pandemic,” he said.
“The way we treat cancer over the next few months will change enormously,” writes a British oncologist in an article published in the Guardian.
“As oncologists, we will have to find a tenuous balance between undertreating people with cancer, resulting in more deaths from the disease in the medium to long term, and increasing deaths from COVID-19 in a vulnerable patient population. Alongside our patients we will have to make difficult decisions regarding treatments, with only low-quality evidence to guide us,” writes Lucy Gossage, MD, consultant oncologist at Nottingham University Hospital, UK.
The evidence to date (from reports from China in Lancet Oncology) suggests that people with cancer have a significantly higher risk of severe illness resulting in intensive care admissions or death when infected with COVID-19, particularly if they recently had chemotherapy or surgery.
“Many of the oncology treatments we currently use, especially those given after surgery to reduce risk of cancer recurrence, have relatively small benefits,” she writes.
“In the current climate, the balance of offering these treatments may shift; a small reduction in risk of cancer recurrence over the next 5 years may be outweighed by the potential for a short-term increase in risk of death from COVID-19. In the long term, more people’s cancer will return if we aren’t able to offer these treatments,” she adds.
Postpone Routine Screening
One thing that can go on the back burner for now is routine cancer screening, which can be postponed for now in order to conserve health system resources and reduce contact with healthcare facilities, says the ACS.
“Patients seeking routine cancer screenings should delay those until further notice,” said Lichtenfeld. “While timely screening is important, the need to prevent the spread of coronavirus and to reduce the strain on the medical system is more important right now.”
But as soon as restrictions to slow the spread of COVID-19 are lifted and routine visits to health facilities are safe, regular screening tests should be rescheduled.
Guidance From ASCO
The American Society of Clinical Oncology (ASCO) has issued new guidance on caring for patients with cancer during the COVID-19 outbreak.
First and foremost, ASCO encourages providers, facilities, and anyone caring for patients with cancer to follow the existing guidelines from the Center for Disease Control and Prevention when possible.
ASCO highlights the CDC’s general recommendation for healthcare facilities that suggests “elective surgeries” at inpatient facilities be rescheduled if possible, which has also been recommended by the American College of Surgeons.
However, in many cases, cancer surgery is not elective but essential, it points out. So this is largely an individual determination that clinicians and patients will need to make, taking into account the potential harms of delaying needed cancer-related surgery.
Systemic treatments, including chemotherapy and immunotherapy, leave cancer patients vulnerable to infection, but ASCO says there is no direct evidence to support changes in regimens during the pandemic. Therefore, routinely stopping anticancer or immunosuppressive therapy is not recommended, as the balance of potential harms that may result from delaying or interrupting treatment versus the potential benefits of possibly preventing or delaying COVID-19 infection remains very unclear.
Clinical decisions must be individualized, ASCO emphasized, and suggested the following practice points be considered:
- For patients already in deep remission who are receiving maintenance therapy, stopping treatment may be an option.
- Some patients may be able to switch from IV to oral therapies, which would decrease the frequency of clinic visits.
- Decisions on modifying or withholding chemotherapy need to consider both the indication and goals of care, as well as where the patient is in the treatment regimen and tolerance to the therapy. As an example, the risk–benefit assessment for proceeding with chemotherapy in patients with untreated extensive small-cell lung cancer is quite different than proceeding with maintenance pemetrexed for metastatic non–small cell lung cancer.
- If local coronavirus transmission is an issue at a particular cancer center, reasonable options may include taking a 2-week treatment break or arranging treatment at a different facility.
- Evaluate if home infusion is medically and logistically feasible.
- In some settings, delaying or modifying adjuvant treatment presents a higher risk of compromised disease control and long-term survival than in others, but in cases where the absolute benefit of adjuvant chemotherapy may be quite small and other options are available, the risk of COVID-19 may be considered an additional factor when evaluating care.
Delay Stem Cell Transplants
For patients who are candidates for allogeneic stem cell transplantation, a delay may be reasonable if the patient is currently well controlled with conventional treatment, ASCO comments. It also directs clinicians to follow the recommendations provided by the American Society of Transplantation and Cellular Therapy and from the European Society for Blood and Marrow Transplantation regarding this issue.
Finally, there is also the question of prophylactic antiviral therapy: Should it be considered for cancer patients undergoing active therapy?
The answer to that question is currently unknown, says ASCO, but “this is an active area of research and evidence may be available at any time.”

Feds tout drug candidates to treat COVID-19
Therapeutics could be available in the near term to help treat COVID-19 patients, according to President Donald Trump.
During a March 19 press briefing, the president highlighted two drugs that could be put into play in the battle against the virus.
The first product is hydroxychloroquine (Plaquenil), a drug used to treat malaria and severe arthritis, is showing promise as a possible treatment for COVID-19.
“The nice part is it’s been around for a long time, so we know that if things go as planned, it’s not going to kill anybody,” President Trump said. “When you go with a brand-new drug, you don’t know that that’s going to happen,” adding that it has shown “very, very encouraging” results as a potential treatment for COVID-19.
He said this drug will be made available “almost immediately.” During the press conference, Food and Drug Administration Commissioner Stephen M. Hahn, MD, suggested the drug would be made available in the context of a large pragmatic clinical trial, enabling the FDA to collect data on it and make a long-term decision on its viability to treat COVID-19.
Dr. Hahn also pointed to the Gilead drug remdesivir – a drug originally developed to fight Ebola and currently undergoing clinical trials – as another possible candidate for a near-term therapeutic to help treat patients while vaccine development occurs.
Dr. Hahn noted that, while the agency is striving to provide regulatory flexibility, safety is paramount. “Let me make one thing clear: FDA’s responsibility to the American people is to ensure that products are safe and effective and that we are continuing to do that.”
He noted that if these and other experimental drugs show promise, physicians can request them under “compassionate use” provisions.
“We have criteria for that, and very speedy approval for that,” Dr. Hahn said. “The important thing about compassionate use ... this is even beyond ‘right to try.’ [We] get to collect the information about that.”
He noted that the FDA is looking at other drugs that are approved for other indications. The examinations of existing therapies are meant to be a bridge as companies work to develop new therapeutics as well as vaccines.
Dr. Hahn also highlighted a cross-agency effort on convalescent plasma, which uses the plasma from a patient who has recovered from COVID-19 infection to help patients fight the virus. “This is a possible treatment; this is not a proven treatment, “ Dr. Hahn said.
Takeda is working on an immunoglobulin treatment based on its intravenous immunoglobulin product Gammagard Liquid.
Julie Kim, president of plasma-derived therapies at Takeda, said the company should be able to go straight into testing efficacy of this approach, given the known safety profile of the treatment. She made the comments during a March 18 press briefing hosted by Pharmaceutical Research and Manufacturers of America (PhRMA). Ms. Kim did caution that this would not be a mass market kind of treatment, as supply would depend on plasma donations from individuals who have fully recovered from a COVID-19 infection. She estimated that the treatment could be available to a targeted group of high-risk patients in 9-18 months.
PhRMA president and CEO Stephen Ubl said the industry is “literally working around the clock” on four key areas: development of new diagnostics, identification of potential existing treatments to make available through trials and compassionate use, development of novel therapies, and development of a vaccine.
There are more than 80 clinical trials underway on existing treatments that could have approval to treat COVID-19 in a matter of months, he said.
Mikael Dolsten, MD, PhD, chief scientific officer at Pfizer, said that the company is working with Germany-based BioNTech SE to develop an mRNA-based vaccine for COVID-19, with testing expected to begin in Germany, China, and the United States by the end of April. The company also is screening antiviral compounds that were previously in development against other coronavirus diseases.
Clement Lewin, PhD, associate vice president of R&D strategy for vaccines at Sanofi, said the company has partnered with Regeneron to launch a trial of sarilumab (Kevzara), a drug approved to treat moderate to severe rheumatoid arthritis, to help treat COVID-19.
Meanwhile, Lilly Chief Scientific Officer Daniel Skovronsky, MD, PhD, noted that his company is collaborating with AbCellera to develop therapeutics using monoclonal antibodies isolated from one of the first U.S. patients who recovered from COVID-19. He said the goal is to begin testing within the next 4 months.
Separately, World Health Organization Director General Tedros Adhanom Ghebreyesus announced during a March 18 press conference that it is spearheading a large international study examining a number of different treatments in what has been dubbed the SOLIDARITY trial. Argentina, Bahrain, Canada, France, Iran, Norway, South Africa, Spain, Switzerland, and Thailand have signed on to be a part of the trial, with more countries expected to participate.
“I continue to be inspired by the many demonstrations of solidarity from all over the world,” he said. “These and other efforts give me hope that together, we can and will prevail. This virus is presenting us with an unprecedented threat. But it’s also an unprecedented opportunity to come together as one against a common enemy, an enemy against humanity.”

20% of U.S. COVID-19 deaths were aged 20-64 years
*Correction, 3/20/2020: An earlier version of this story misstated the age range for COVID-19 deaths. The headline of this story was corrected to read "20% of COVID-19 deaths were aged 20-64 years" and the text was adjusted to reflect the correct age range.
A review of more than 4,000 U.S. patients who were diagnosed with novel coronavirus infection (COVID-19) shows that an unexpected 20% of deaths occurred among adults aged 20-64 years, and 20% of those hospitalized were aged 20-44 years.
The expectation has been that people over 65 are most vulnerable to COVID-19 infection, but this study indicates that, at least in the United States, a significant number of patients under 45 can land in the hospital and can even die of the disease.
To assess rates of hospitalization, admission to an ICU, and death among patients with COVID-19 by age group, the Centers for Disease Control and Prevention analyzed 4,226 COVID-19 cases in the United States that were reported between Feb. 12 and March 16.
Overall, older patients in this group were the most likely to be hospitalized, to be admitted to ICU, and to die of COVID-19. A total of 31% of the cases, 45% of hospitalizations, 53% of ICU admissions, and 80% of deaths occurred in patients aged 65 years and older. “Similar to reports from other countries, this finding suggests that the risk for serious disease and death from COVID-19 is higher in older age groups,” said the investigators. “In contrast, persons aged [19 years and younger] appear to have milder COVID-19 illness, with almost no hospitalizations or deaths reported to date in the United States in this age group.”
But compared with the under-19 group, patients aged 20-44 years appeared to be at higher risk for hospitalization and ICU admission, according to the data published March 18 in Morbidity and Mortality Weekly Report.
The researchers excluded from their analysis patients who repatriated to the United States from Wuhan, China, and from Japan, including patients repatriated from cruise ships. Data on serious underlying health conditions were not available, and many cases were missing key data, they noted.
Among 508 patients known to have been hospitalized, 9% were aged 85 years or older, 36% were aged 65-84 years, 17% were aged 55-64 years, 18% were 45-54 years, and 20% were aged 20-44 years.
Among 121 patients admitted to an ICU, 7% were aged 85 years or older, 46% were aged 65-84 years, 36% were aged 45-64 years, and 12% were aged 20-44 years. Between 11% and 31% of patients with COVID-19 aged 75-84 years were admitted to an ICU.
Of 44 deaths, more than a third occurred among adults aged 85 years and older, and 46% occurred among adults aged 65-84 years, and 20% occurred among adults aged 20-64 years.
More follow-up time is needed to determine outcomes among active cases, the researchers said. These results also might overestimate the prevalence of severe disease because the initial approach to testing for COVID-19 focused on people with more severe disease. “These preliminary data also demonstrate that severe illness leading to hospitalization, including ICU admission and death, can occur in adults of any age with COVID-19,” according to the CDC.

*Correction, 3/20/2020: An earlier version of this story misstated the age range for COVID-19 deaths. The headline of this story was corrected to read "20% of COVID-19 deaths were aged 20-64 years" and the text was adjusted to reflect the correct age range.
A review of more than 4,000 U.S. patients who were diagnosed with novel coronavirus infection (COVID-19) shows that an unexpected 20% of deaths occurred among adults aged 20-64 years, and 20% of those hospitalized were aged 20-44 years.
The expectation has been that people over 65 are most vulnerable to COVID-19 infection, but this study indicates that, at least in the United States, a significant number of patients under 45 can land in the hospital and can even die of the disease.
To assess rates of hospitalization, admission to an ICU, and death among patients with COVID-19 by age group, the Centers for Disease Control and Prevention analyzed 4,226 COVID-19 cases in the United States that were reported between Feb. 12 and March 16.
Overall, older patients in this group were the most likely to be hospitalized, to be admitted to ICU, and to die of COVID-19. A total of 31% of the cases, 45% of hospitalizations, 53% of ICU admissions, and 80% of deaths occurred in patients aged 65 years and older. “Similar to reports from other countries, this finding suggests that the risk for serious disease and death from COVID-19 is higher in older age groups,” said the investigators. “In contrast, persons aged [19 years and younger] appear to have milder COVID-19 illness, with almost no hospitalizations or deaths reported to date in the United States in this age group.”
But compared with the under-19 group, patients aged 20-44 years appeared to be at higher risk for hospitalization and ICU admission, according to the data published March 18 in Morbidity and Mortality Weekly Report.
The researchers excluded from their analysis patients who repatriated to the United States from Wuhan, China, and from Japan, including patients repatriated from cruise ships. Data on serious underlying health conditions were not available, and many cases were missing key data, they noted.
Among 508 patients known to have been hospitalized, 9% were aged 85 years or older, 36% were aged 65-84 years, 17% were aged 55-64 years, 18% were 45-54 years, and 20% were aged 20-44 years.

New sickle cell drugs give hope, but access remains a barrier
Sickle cell disease (SCD) is an incurable genetic blood disorder that reduces patients’ lifespan and quality of life. Many patients live into their 40s or 50s. Yet, throughout their lives, patients are plagued by lethargy, unpredictable painful crises, and frequent hospitalizations. For nearly 20 years, clinicians only had one drug to treat SCD. Since 2017, three new drugs have been approved, but their costs and lack of long-term data have spawned questions regarding access and benefit.
“SCD reduces lifespan by 30 years, and that’s very hard to quantify,” says Ifeyinwa Osunkwo, MD, professor of medicine and pediatrics and director of Sickle Cell Disease Enterprise at the Levine Cancer Institute at Atrium Health in Charlotte, N.C. “If you put a dollar amount on what someone would make working for 30 adult years, that would be more reflective of the true cost of treating the disease.”
In 1984, hydroxyurea (Hydrea, Droxia) became the first drug to treat SCD in adults.
Originally developed as a myelosuppressive antineoplastic, hydroxyurea is used to treat resistant chronic myeloid leukemia and certain head and neck cancers. In SCD, it increases levels of hemoglobin and fetal hemoglobin.
Despite its benefit, hydroxyurea has two major drawbacks: It is only effective in two genotypes – HbSS or HbS/Beta0thal.
HbSS or HbS/Beta0thal genotypes account for 60% of the SCD population, but further studies are required to elucidate hydroxyurea’s effect in other forms of SCD, according to Dr. Osunkwo.
Secondly, hydroxyurea only reduces the frequency of painful episodes by 50% – not enough to ameliorate the pain, said John J. Strouse, MD, associate professor of medicine at Duke University School of Medicine.
Newer therapies offer the potential to enhance the effects of hydroxyurea when used concomitantly. They also give clinicians additional options for patients who either fail hydroxyurea therapy or for whom it is inappropriate.
The amino acid L-glutamine (Endari) became the second drug approved for sickle cell in 2017. Indicated for patients 5 years of age and older, Dr. Osunkwo says many patients were thrilled to have a nonchemotherapeutic option available. However, the medical community received the drug with some skepticism. “The data show Endari is moderately effective at best,” said Dr. Strouse. “Also, the mechanism of action is unclear.”
Additionally, the drug’s powder form and twice-daily dosing regimen make adherence more challenging than swallowing a few hydroxyurea tablets or capsules once a day. In Dr. Osunkwo’s experience, patients who respond best to Endari tend to be those who are naturally motivated individuals who are intentional in their efforts at optimizing their nutrition and self-care.
“It takes a lot to be adherent to Endari,” she said. “You have to work at it.”
On Nov. 15, 2019, the FDA approved crizanlizumab-tmca (Adakveo) for patients 16 years of age and older to decrease the occurrence of vasoocclusive crises.
The drug works by blocking selectin – a protein involved in the painful vascular pathophysiology. Patients receive a loading dose of 5 mg/kg administered via intravenous infusion over 30 minutes at the initiation of therapy, as well as weeks 2 and 4. After that, patients undergo treatment once a month. Nausea, back pain, pyrexia, and arthralgia are the most frequently reported adverse reactions. Clinicians must monitor patients for signs and symptoms of infusion-related reactions.
Ten days later, the FDA approved voxelotor (Oxbryta) for patients ages 12 years and up. The drug inhibits hemoglobin S polymerization and increases hemoglobin levels. Like hydroxyurea, the drug offers the convenience of once-daily dosing, and the tablet can be taken without regard to food. The drug dose requires adjustment for patients with severe hepatic impairment. Headache, fatigue, rash, and gastrointestinal disturbances such as diarrhea, nausea, and abdominal pain fall among the most commonly reported side effects.
Endari, Adakveo, and Oxbryta can all be used as monotherapy. They also provide additional benefits in reducing pain and hospitalizations and improving anemia when used concomitantly with hydroxyurea.
Like so many drugs, these novel therapies are expensive. The cost of these novel treatments has raised some eyebrows.
Annual costs of generic hydroxyurea range in the neighborhood of $1,200. In a 2017 CNBC interview, Endari manufacturer Emmaus stated that it aimed to keep drug costs under $20,000 a year. Annual costs for Adakveo and Oxbryta costs are in the neighborhood of $100,000. Adakveo manufacturer Novartis reportedly priced vials at $2,347. Most patients will require at least three of the maximum four vials per treatment. In a press release, Global Therapeutics stated that Oxbyta would cost $10,417 a month.
However, Dr. Osunkwo says the benefits of these new drugs far exceed the costs from both monetary and quality of life standpoints.
“Sickle cell disease is costly to manage,” she said in an interview. “One hospitalization can cost $10,000.”
Additionally, many SCD patients are publicly insured because of the profound disability and loss of productive work they encounter as a direct consequence of their disease and its complications. Those too sick to complete their high school and postsecondary education find limited employment opportunities.
Those fortunate enough to secure employment face significantly fewer years they can work because their pain, fatigue, frequent hospitalizations, and cumulative organ damage result in permanent disability. Only a smaller number of patients with less severe disease manifestations can secure steady employment and pursue careers that allow them to obtain private insurance.
Even if the newer therapies can help cut some costs, clinicians should be aware that prior authorizations can delay patient access to Adakveo and Oxbyta.
“We wrote the first prescription for Oxbryta in November of 2019, but the prior authorization wasn’t approved until February of 2020,” she said. Adding Adakveo to her institution’s formulary required several months of navigation. Given the arduous process, Dr. Osunkwo anticipates it will take at least year after approval before Adakveo is available for all eligible patients.
The long-term impact of these drugs also remains to be seen, so hydroxyurea will likely remain the drug of choice for many patients, according to Dr. Strouse.
Dr. Osunkwo believes SCD needs more drugs in order to truly optimize outcomes, contain costs, and enhance the patient experience.
Dr. Osunkwo reports consultancy and being on the speaker’s bureau and participating in the advisory board for Novartis, which markets Adakveo, and relationships with a variety of other pharmaceutical companies. She is the editor in chief for Hematology News. Dr. Strouse reports consultancy for Global Therapeutics, which markets Oxbryta.

Rheumatologists to share knowledge in COVID-19 patient-centered registry
Rheumatologists the world over are joining forces to create a COVID-19 rheumatology registry designed to help both patients and providers learn from each other regarding management of rheumatologic diseases and risk of infection among patients who are commonly on chronic immunosuppressive medications.
The COVID-19 Global Rheumatology Alliance, a consortium supported by more than 50 major clinical societies and foundations, quickly grew from messages on social media platforms to a multinational group focused on the common goal of helping to “guide rheumatology clinicians in assessing and treating patients with rheumatologic disease and in evaluating the risk of infection in patients on immunosuppression.”
As of this writing, the rheumatology registry is still being assembled, and organizers are currently seeking approvals from various authorities. As of March 17, 2020, the Institutional Review Board (IRB) at the University of California, San Francisco, has determined that the registry is exempt from IRB approval requirements, a finding that should apply elsewhere in the United States, according to the registry website.
When it is fully up and running, clinicians will be able to report to the secure website on any and all cases of patients with rheumatologic disorders who present with COVID-19 of any severity, including patients with mild disease or asymptomatic patients who test positive.
“We are aiming for 5 to 10 minutes to input the data. We don’t want to drag them away from their clinical duties too much, but if clinicians are able to spare a few minutes to put in details about a patient, then that’s going to help build our knowledge and it’s going to help them with other patients,” said Philip Robinson, MBChB, associate professor of medicine at the University of Queensland in Brisbane, Australia, and the chief architect of the registry.
The data will be deindentified, with no protected health care information required or included, and made available to the global rheumatology community, but the registry will not offer clinical advice, Dr. Robinson said in an interview.
“This is observational data, it’s not randomized, but our approach is that some data is better than no data,” he said.
He also cautioned that the data will need careful interpretation, because information about patients with mild symptoms may offer false reassurances about the severity or extent of infection.
“For example, the patients with severe cases may be in the ICU, and can’t tell their doctors that they’re on methotrexate, so you can see how we need to be really careful about the messages from that data and not misinterpret it,” he said.
The COVID-19 rheumatology registry was inspired by a similar effort in the gastroenterology community, the Surveillance Epidemiology of Coronavirus Under Research Exclusion (SECURE-IBD) registry. Patients with inflammatory bowel disease are often treated with immunosuppressive biologic agents familiar to the rheumatology community, such as infliximab (Remicade and biosimilars) and adalimumab (Humira and biosimilars), and methotrexate.

Rheumatologists the world over are joining forces to create a COVID-19 rheumatology registry designed to help both patients and providers learn from each other regarding management of rheumatologic diseases and risk of infection among patients who are commonly on chronic immunosuppressive medications.
The COVID-19 Global Rheumatology Alliance, a consortium supported by more than 50 major clinical societies and foundations, quickly grew from messages on social media platforms to a multinational group focused on the common goal of helping to “guide rheumatology clinicians in assessing and treating patients with rheumatologic disease and in evaluating the risk of infection in patients on immunosuppression.”
As of this writing, the rheumatology registry is still being assembled, and organizers are currently seeking approvals from various authorities. As of March 17, 2020, the Institutional Review Board (IRB) at the University of California, San Francisco, has determined that the registry is exempt from IRB approval requirements, a finding that should apply elsewhere in the United States, according to the registry website.
When it is fully up and running, clinicians will be able to report to the secure website on any and all cases of patients with rheumatologic disorders who present with COVID-19 of any severity, including patients with mild disease or asymptomatic patients who test positive.
“We are aiming for 5 to 10 minutes to input the data. We don’t want to drag them away from their clinical duties too much, but if clinicians are able to spare a few minutes to put in details about a patient, then that’s going to help build our knowledge and it’s going to help them with other patients,” said Philip Robinson, MBChB, associate professor of medicine at the University of Queensland in Brisbane, Australia, and the chief architect of the registry.
The data will be deindentified, with no protected health care information required or included, and made available to the global rheumatology community, but the registry will not offer clinical advice, Dr. Robinson said in an interview.
“This is observational data, it’s not randomized, but our approach is that some data is better than no data,” he said.
He also cautioned that the data will need careful interpretation, because information about patients with mild symptoms may offer false reassurances about the severity or extent of infection.
“For example, the patients with severe cases may be in the ICU, and can’t tell their doctors that they’re on methotrexate, so you can see how we need to be really careful about the messages from that data and not misinterpret it,” he said.

Real-world shortages not addressed in new COVID-19 guidance
Newly updated guidance on treating patients with the novel coronavirus (COVID-19) has been published by the World Health Organization.
While it can’t replace clinical judgment or specialist consultation, the new guidance may help strengthen the clinical management of patients when COVID-19 is suspected, according to its authors.
The guidance, adapted from an earlier edition focused on the management of suspected Middle East respiratory syndrome coronavirus (MERS-CoV), covers best practices for triage, infection prevention and control, and optimized supportive care for mild, severe, or critical coronavirus disease 2019 (COVID-19).
“This guidance should serve as a foundation for optimized supportive care to ensure the best possible chance for survival,” the authors wrote in the guidance.
While the WHO guidance does provide solid facts to support best practices for managing COVID-19, providers will also need to look beyond the document to tackle real-world issues, said David M. Ferraro, MD, FCCP, a pulmonary and critical care physician and associate professor of medicine at National Jewish Health in Denver.
For example, while the guidelines address the importance of screening and triage, limited COVID-19 testing may be a barrier to timely diagnoses that might compel more individuals to comply with social distancing recommendations, according to Dr. Ferraro, vice chair of the Fundamental Disaster Management Committee for the Society of Critical Care Medicine (SCCM).
“If we’re not providing people with confirmation that they have the virus, they may potentially continue to be spreaders of the disease, because they don’t have that absolute proof,” Dr. Ferraro said in an interview. “I think that’s where we are limited right now, because often we’re not able to tell the mild symptomatic people – or even the asymptomatic people – that they really need to play a role in preventing further spread.”
Likewise, the guidelines provide sound guidance on management of severe or critical COVID-19, according to Dr. Ferraro, yet they don’t address the potential for shortages of trained health care personnel to handle more severe cases requiring ventilation. That’s clearly an important issue, he said, especially with recent reports that the COVID-19 pandemic has pushed Italian intensive care units (ICUs) to the brink of collapse.
If the pandemic reaches crisis levels in the United States, nearly 1 million people would need ventilatory support, according to a recent report from SCCM on U.S. resource availability for COVID-19. And while there are an estimated 200,000 ventilators available in the United States, it’s estimated in that report that only 135,000 patients could be handled at a time, given the shortage of ICU physicians, advanced practice providers, nurses, and respiratory therapists with training in mechanical ventilation.
“If our ICUs get overwhelmed and swarmed, we may have the technology available, but we may not have enough resources and personnel to safely manage the number of patients,” Dr. Ferraro said.
The solution to that, according to the SCCM report, is to focus on expanding the pool of trained professionals who may be needed, not only to mechanically ventilate patients with COVID-19, but also to care for other critically ill patients routinely cared for in the ICU. They also suggest adopting a “tiered staffing strategy” in which non-ICU trained health care providers augment the capacity of experienced ICU staff.
With the prospect of untrained health care workers in mind, the WHO guidance could be a valuable resource for those who do have to jump into ICU roles, according to Dr. Ferraro.
The WHO also stresses immediate implementation of appropriate measures for infection prevention and control (IPC). According to their guidance, IPC needs to be initiated right at the point where the patient enters the hospital, with screening done at the first point of contact in the emergency department or outpatient clinics.
If patients are suspected to have COVID-19, they should receive a mask, and should be directed to a separate area where they are kept at least 1 meter apart from other individuals with suspected COVID-19, according to the WHO. (The Centers for Disease Control and Prevention recommends maintaining a distance of 6 feet to prevent spread of illness).
Beyond standard precautions such as hand washing and use of personal protective equipment, health care workers should do a point-of-care risk assessment at every patient contact to determine whether additional precautions are required.
Having standard IPC measures in place is “paramount,” according to Dr. Ferraro, for a disease that has no available vaccine, no proven treatments, and a stealthy spread fueled by asymptomatic carriers.
“Those are huge weapons against us, and the only thing we really have to knock this down is really infection prevention control, so that truly is at the cornerstone,” he said. “These are things that we must strictly follow.”

Lopinavir-ritonavir trial results ‘disappointing’ for severe COVID-19
No difference in the primary endpoint of the time to clinical improvement was seen in an open-label trial of the antiretroviral drug lopinavir-ritonavir versus standard of care in adult patients hospitalized with severe COVID-19.
The median time to clinical improvement – defined as the time from randomization to either an improvement of two points on a seven-category ordinal scale or discharge from the hospital, whichever was first – was 16 days in both groups (hazard ratio, 1.31; 95% confidence interval 0.95-1.85; P = .09).
Although a numerically lower number of deaths were recorded at 28 days (19.2% vs. 25%) with the antiretroviral treatment versus standard of care, a similar percentage of patients had detectable levels of viral RNA in throat swabs taken at various time points during the study, Chinese researchers reported in the New England Journal of Medicine.
Bai Cao, M.D, from the China-Japan Friendship Hospital and Chinese Academy of Medical Sciences, both in Beijing, and associates, performed a randomized, controlled, trial of 199 adult patients hospitalized at the Jin Yin-Tan Hospital in Wuhan in Hubei Province, China.
For inclusion, patients had to have laboratory confirmed infection with SARS-Cov-2, the virus that causes COVID-19; pneumonia confirmed by chest imaging; and severely reduced oxygen saturation (94% or less while breathing ambient air or a ratio of the partial pressure of oxygen to the fraction of inspired oxygen of less than 300 mm Hg).
Patients were randomized to receive either a combination of lopinavir (400 mg) and ritonavir (100 mg) twice a day on top of standard care (n = 99) or to standard care alone (n = 100) for 14 days. “Because of the emergency nature of the trial, placebos of lopinavir-ritonavir were not prepared,” Dr. Cao et al. explained, noting that standard care consisted of supplemental oxygen, ventilation, antibiotic treatment, vasopressor support, renal-replacement therapy, and extracorporeal membrane oxygenation.
While the trial did not meet its primary endpoint, Dr. Cao et al. reported that patients in the lopinavir-ritonavir group had a shorter stay in the intensive care unit than did those in the standard-care group, at a median of 6 versus 11 days. They also reported that the duration from randomization to hospital discharge was numerically shorter, at a median of 12 versus 14 days. Furthermore, there was a higher percentage of patients with clinical improvement at day 14 in the lopinavir-ritonavir group than in the standard-care group (45.5% vs. 30.0%)
“The trial was initiated in rapid response to the COVID-19 public health emergency, at which time there was very limited information about clinical outcomes in hospitalized patients with COVID-19,” the researchers observed. “The question of whether earlier lopinavir-ritonavir treatment in COVID-19 could have clinical benefit is an important one that requires further study,” they wrote.
Among the trial’s limitations are it was not blinded and the researchers do not have data on the lopinavir exposure levels in the trial participants.
“This was a heroic effort” in a “particularly challenging population,” Lindsey R. Baden, MD, and Eric J. Rubin, MD, stated in an editorial accompanying the article (Baden LR and Rubin EJ. New Engl J Med. March 18, 2020. doi: 10.1056/NEJMe2005477). “Unfortunately, the trial results were disappointing,” they noted.
“The secondary end points provide both reason for hope and reason for discouragement,” wrote Dr. Baden and Dr. Rubin. The lack of effect on viral shedding, however, “strongly [suggests] that it did not have the activity desired” they observed.
Dr. Baden and Dr. Rubin commented that one of the important takeaways from the trial is that “the investigators appropriately prioritized speed, designing a trial that could rapidly produce an answer.” They continued that the investigators had shown that “rapidly initiated, high-quality randomized clinical trials are possible in epidemic conditions” and that results of such trials, whether they are positive or negative, “will be central to clinical care as the dangerous coronavirus outbreak continues.”
As it stands, more than 100 trials are listed in the ClinicalTrials.gov database as testing a wide range of different treatment approaches for COVID-19. These include trials investigating if sarilumab, hydroxychloroquine, fingolimod, bevacizumab, and losartan might have a role to play. There are also trials looking at the potential of other antiviral agents, such as Gilead’s investigational drug remdesivir, which has shown to have in vitro and in vivo activity against many emerging viral pathogens that cause Ebola, Middle Eastern Respiratory Syndrome, and Severe Acute Respiratory Syndrome.
Dr. Cao’s trial was supported by grants from Major Projects of National Science and Technology on New Drug Creation and Development and from the Chinese Academy of Medical Sciences (CAMS) Emergency Project of Covid-19, and a National Science Grant for Distinguished Young Scholars.

Patients with COVID-19 may face risk for liver injury
Patients with COVID-19 may be at risk for liver injury, but mechanisms of damage remain unclear, according to investigators.
Proposed mechanisms include direct virus-induced effects, immune-induced damage due to excessive inflammatory responses, and drug-induced injury, reported lead author Ling Xu of Huazhong University of Science and Technology, Wuhan, China, and colleagues.
“From a clinical perspective, in addition to actively dealing with the primary disease caused by coronavirus infection, attention should also be paid to monitor the occurrence of liver injury, and to the application of drugs which may induce liver damage,” the investigators wrote in Liver International. “Patients with liver damage are advised to be treated with drugs that could both protect liver functions and inhibit inflammatory responses, such as ammonium glycyrrhizinate, which may, in turn, accelerate the process of disease recovery.”
The review of liver injury associated with major pathogenic coronaviruses included severe acute respiratory syndrome coronavirus (SARS-CoV), the Middle East respiratory syndrome coronavirus (MERS-CoV), and the newly emergent SARS-CoV-2, which causes COVID-19.
In cases of COVID-19, reported incidence of liver injury ranges from 15% to 53%, based on elevations of alanine transaminase (ALT) and aspartate aminotransferase (AST), along with slightly elevated bilirubin levels. In severe cases, albumin decreases have also been documented.
Liver injury appears to be significantly more common among those with severe infection. In one cohort of 82 patients who died from COVID-19, the incidence of liver injury was 78%, while another study of 36 nonsurvivors reported a rate of 58%.
According to the investigators, both bile duct epithelial cells and liver cells express angiotensin converting enzyme II (ACE2), which is an entry receptor for SARS-CoV-2; however, expression of ACE2 in bile duct cells is “much higher” than in liver cells, and comparable with alveolar type 2 cells in the lungs.
“Bile duct epithelial cells are known to play important roles in liver regeneration and immune response,” the investigators noted.
Beyond direct- and immune-induced effects of COVID-19, postmortem findings suggest that drug-induced liver injury may also be a possibility, with a number of theoretical culprits, including antibiotics, steroids, and antivirals. Although the investigators emphasized that data are insufficient to pinpoint an exact agent, they highlighted a recent preprint study, which reported a significantly higher rate of lopinavir/ritonavir administration among patients with abnormal liver function, compared with those who had normal liver function (56.1% vs. 25%; P = .009).
“Drug-induced liver injury during the treatment of coronavirus infection should not be ignored and needs to be carefully investigated,” the investigators concluded.

COVID-19 will test medical supply stocks
In a JAMA Live Stream interview, in the United States.
Dr. Fauci got into the details of what is known, what is unknown, what is being done in laboratories, and what clinical elements are still not understood about this disease.
The next several weeks, he said, are likely to tell the tale of whether our health care system is up to the challenge of care for the most ill among those who will be affected by COVID-19.
“It shouldn’t panic or frighten us, but we have to know we’re dealing with a very serious problem that we have to address, and we have to deal with it in a very bold way,” said Dr. Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health.
Speaking in an interview with JAMA Editor in Chief Howard Bauchner, MD, Dr. Fauci said the situation favors action over fear. “Let’s apply that energy to doing the things that we know can mitigate this.”
He added that he heard the message loud and clear from health care leaders in Italy and France during a World Health Organization coronavirus call earlier in the day. Officials in those countries, he said, were “almost pleading with the rest of the world to please take this very seriously, because it happens all of a sudden – very abruptly. ... The best time to mitigate is before that happens, because if you wait until after it happens you’re playing catch-up.”
Dr. Bauchner, noting that strict social distancing has been underway in many parts of the United States for several days, posited that, by early April, “We’ll really have a sense if we can manage in terms of serious illness.” Seattle, New York, Boston, and the San Francisco Bay Area may experience demand that outstrips ICU capacity at that point, but the rest of the country, he said, “is doing relatively well.”
Stress test on the health care system
Dr. Fauci agreed with this statement and added: “We’re going to know – for better or worse – whether we have enough of what it takes to be able to practice the kind of medicine that we optimally would want to practice.
In the matter of a week or 2 ... I think we’ll get a feel for whether or not we really have enough of the supplies that it takes.”
The well-publicized regional shortages in personal protective equipment (PPE) are forcing tough choices in some areas. As expedited – and even drive-through – testing begins, some of the demand for testing-related PPE may abate, especially if protocols include self-administration of nasal swabs, he noted.
Dr. Fauci added that the strategic national stockpile of medical supplies and equipment has not yet been tapped, “but you need to backfill that as quickly as you can once you start drawing from the strategic national stockpile.”
Returning to work after COVID-19 infection
Regarding the thorny question of when health care workers should be permitted to return to work after coronavirus infection, “it’s an evolving story,” said Dr. Fauci. Current guidance advises that health care providers stay away from work until two negative tests after resolution of fever and improvement of respiratory symptoms, or 3 fever-free days.
“We are approaching a point where you’re going to get enough people who are getting infected that we aren’t going to be able to do that,” he said. Depending on the stress to the health care system in a given locality, he said that facilities are going to have to “decide with good judgment” when health care workers go back on the job after coronavirus infection.
Asked how soon an individual would reliably test positive for COVID-19 after exposure, Dr. Fauci said, “We don’t know the answer to that. ... We can surmise it ...” He noted that it’s a median of about 5 days with a range of 2 to 14 days, before an infected individual becomes symptomatic. “I can say it’s not going to happen immediately,” he added, noting that he wouldn’t expect to see a positive test until about 2 days after exposure at the earliest. “When you get to the point where you are symptomatic, you’re almost certainly going to be positive then. ... This is just an extrapolation,” rather than conclusions drawn from solid data, he emphasized.
Higher risk reported in cardiac patients
Dr. Bauchner, who was relaying questions sent in from physicians during the live-streamed interview, asked about a newly issued joint statement from the American Heart Association, American College of Cardiology, and the Heart Failure Society of America, which on March 17 affirmed that individuals on ACE inhibitors and angiotensin receptor blockers (ARBs) continue that therapy if they should become ill with COVID-19. The European Society of Cardiology issued a similar recommendation a few days prior.
Despite these societies’ statements, Dr. Fauci pointed to population-level data in Italy as suggesting that the case isn’t yet closed. “We really need to get data, and we need to get data fast. There’s a mechanistic rationale for the concern. It’s there, and it’s firm,” he said. The theoretical concern is that ACE inhibitors can upregulate expression of the ACE-2 protein on cell membranes, which is the entry point for SARS-Cov-2 to enter cells.
He added that he remains concerned about the number of coronavirus fatalities of patients in Italy who had hypertension as their only, or primary, underlying health problem.“That to me was a bit of a red flag,” he said. “Patients with hypertension almost certainly had a physician, and the physician almost certainly treated that person with medication. Why should someone who has hypertension that was well controlled have a much greater chance of dying?” he asked, noting that “I look at a person with well-controlled hypertension as a relatively healthy person. I don’t know what the answer is, but somebody has to look very carefully,” ideally by means of a natural history study that identifies medications used by those who died from coronavirus.
Potential therapies
Regarding potential therapies for COVID-19, Dr. Fauci acknowledged the social media buzz and flurry of medical letters and case reports about the use of hydroxychloroquine (Plaquenil) to treat active infection. He said that he and other researchers are “in active discussion” about how best to study the efficacy and safety of hydroxychloroquine, but he also acknowledged that many treating clinicians will use hydroxychloroquine empirically in the absence of other treatments with proven efficacy.
Clinical trials underway in China for antiviral medication are facing some enrollment challenges currently “because people want to get the drug,” said Dr. Fauci. “They don’t want to be in the trial; they just want to get the drug.” Though each of two trials has targeted approximately 500 participants as the number needed for sufficient statistical power, Dr. Fauci urged Chinese data safety monitoring boards to “take a close look” at the data already accrued for the several hundred patients who have already enrolled for the studies “to see if there’s any hint of efficacy.”

COVID-19 in China: Children have less severe disease, but are vulnerable
Clinical manifestations of COVID-19 infection among children in mainland China generally have been less severe than those among adults, but children of all ages – and infants in particular – are vulnerable to infection, according to a review of 2,143 cases.
Further, infection patterns in the nationwide series of all pediatric patients reported to the Chinese Center for Disease Control and Prevention from Jan. 16 to Feb. 8, 2020, provide strong evidence of human-to-human transmission, Yuanyuan Dong, MPH, a research assistant at Shanghai Children’s Medical Center, Shanghai Jiao Tong University, China, and colleagues reported in Pediatrics.
Of the 2,143 patients included in the review, 57% were boys and the median age was 7 years; 34% had laboratory-confirmed infection and 67% had suspected infection. More than 90% had asymptomatic, mild, or moderate disease (4%, 51%, and 39%, respectively), and 46% were from Hubei Province, where the first cases were reported, the investigators found.
The median time from illness onset to diagnosis was 2 days, and there was a trend of rapid increase of disease at the early stage of the epidemic – with rapid spread from Hubei Province to surrounding provinces – followed by a gradual and steady decrease, they noted.
“The total number of pediatric patients increased remarkably between mid-January and early February, peaked around February 1, and then declined since early February 2020,” they wrote. The proportion of severe and critical cases was 11% for infants under 1 year of age, compared with 7% for those aged 1-5 years; 4% for those aged 6-10 years; 4% for those 11-15 years; and 3% for those 16 years and older.
As of Feb. 8, 2020, only one child in this group of study patients died and most cases of COVID-19 symptoms were mild. There were many fewer severe and critical cases among the children (6%), compared with those reported in adult patients in other studies (19%). “It suggests that, compared with adult patients, clinical manifestations of children’s COVID-19 may be less severe,” the investigators suggested.
“As most of these children were likely to expose themselves to family members and/or other children with COVID-19, it clearly indicates person-to-person transmission ” of novel coronavirus 2019, they said, adding that similar evidence of such transmission also has been reported from studies of adult patients.
The reasons for reduced severity in children versus adults remain unclear, but may be related to both exposure and host factors, Ms. Dong and associates said. “Children were usually well cared for at home and might have relatively [fewer] opportunities to expose themselves to pathogens and/or sick patients.”
The findings demonstrate a pediatric distribution that varied across time and space, with most cases concentrated in the Hubei province and surrounding areas. No significant gender-related difference in infection rates was observed, and although the median patient age was 7 years, the range was 1 day to 18 years, suggesting that “all ages at childhood were susceptible” to the virus, they added.
The declining number of cases over time further suggests that disease control measures implemented by the government were effective, and that cases will “continue to decline, and finally stop in the near future unless sustained human-to-human transmissions occur,” Ms. Dong and associates concluded.
In an accompanying editorial, Andrea T. Cruz, MD, of Baylor College of Medicine, Houston, and Steven L. Zeichner, MD, PhD, of the University of Virginia, Charlottesville, said the findings regarding reduced severity among children versus adults with novel coronavirus 2019 infection are consistent with data on non-COVID-19 coronavirus.
They pointed out that Ms. Dong and associates did find that 13% of virologically-confirmed cases had asymptomatic infection, “a rate that almost certainly understates the true rate of asymptomatic infection, since many asymptomatic children are unlikely to be tested.”
Of the symptomatic children, “5% had dyspnea or hypoxemia (a substantially lower percentage than what has been reported for adults) and 0.6% progressed to acute respiratory distress syndrome (ARDS) or multiorgan system dysfunction”; this also is at a lower rate than seen in adults, they said.
Very young children –infants or children in preschool – were more likely to have severe clinical manifestations than children who were older.
Thus, it appears that certain subpopulations of children are at increased risk for more significant COVID-19 illness: “younger age, underlying pulmonary pathology, and immunocompromising conditions,” Dr. Cruz and Dr. Zeichner suggested.
The two editorialists said the findings suggest children “may play a major role in community-based viral transmission.” Evidence suggests that children may have more upper respiratory tract involvement and that fecal shedding may occur for several weeks after diagnosis; this raises concerns about fecal-oral transmission, particularly for infants and children, and about viral replication in the gastrointestinal tract, they said. This has substantial implications for community spread in day care centers, schools, and in the home.
A great deal has been learned about COVID-19 in a short time, but there still is much to learn about the effect of the virus on children, the impact of children on viral spread, and about possible vertical transmission, they said.
“Widespread availability of testing will allow for us to more accurately describe the spectrum of illness and may result in adjustment of the apparent morbidity and mortality rate as fewer ill individuals are diagnosed,” Dr. Cruz and Dr. Zeichner wrote, adding that “rigorously gauging the impact of COVID-19 on children will be important to accurately model the pandemic and to ensure that appropriate resources are allocated to children requiring care.”
They noted that understanding differences in children versus adults with COVID-19 “can yield important insights into disease pathogenesis, informing management and the development of therapeutics.”

Of the 2,143 patients included in the review, 57% were boys and the median age was 7 years; 34% had laboratory-confirmed infection and 67% had suspected infection. More than 90% had asymptomatic, mild, or moderate disease (4%, 51%, and 39%, respectively), and 46% were from Hubei Province, where the first cases were reported, the investigators found.
The median time from illness onset to diagnosis was 2 days, and there was a trend of rapid increase of disease at the early stage of the epidemic – with rapid spread from Hubei Province to surrounding provinces – followed by a gradual and steady decrease, they noted.
“The total number of pediatric patients increased remarkably between mid-January and early February, peaked around February 1, and then declined since early February 2020,” they wrote. The proportion of severe and critical cases was 11% for infants under 1 year of age, compared with 7% for those aged 1-5 years; 4% for those aged 6-10 years; 4% for those 11-15 years; and 3% for those 16 years and older.
As of Feb. 8, 2020, only one child in this group of study patients died and most cases of COVID-19 symptoms were mild. There were many fewer severe and critical cases among the children (6%), compared with those reported in adult patients in other studies (19%). “It suggests that, compared with adult patients, clinical manifestations of children’s COVID-19 may be less severe,” the investigators suggested.
“As most of these children were likely to expose themselves to family members and/or other children with COVID-19, it clearly indicates person-to-person transmission ” of novel coronavirus 2019, they said, adding that similar evidence of such transmission also has been reported from studies of adult patients.
The reasons for reduced severity in children versus adults remain unclear, but may be related to both exposure and host factors, Ms. Dong and associates said. “Children were usually well cared for at home and might have relatively [fewer] opportunities to expose themselves to pathogens and/or sick patients.”
The findings demonstrate a pediatric distribution that varied across time and space, with most cases concentrated in the Hubei province and surrounding areas. No significant gender-related difference in infection rates was observed, and although the median patient age was 7 years, the range was 1 day to 18 years, suggesting that “all ages at childhood were susceptible” to the virus, they added.
The declining number of cases over time further suggests that disease control measures implemented by the government were effective, and that cases will “continue to decline, and finally stop in the near future unless sustained human-to-human transmissions occur,” Ms. Dong and associates concluded.
In an accompanying editorial, Andrea T. Cruz, MD, of Baylor College of Medicine, Houston, and Steven L. Zeichner, MD, PhD, of the University of Virginia, Charlottesville, said the findings regarding reduced severity among children versus adults with novel coronavirus 2019 infection are consistent with data on non-COVID-19 coronavirus.
They pointed out that Ms. Dong and associates did find that 13% of virologically-confirmed cases had asymptomatic infection, “a rate that almost certainly understates the true rate of asymptomatic infection, since many asymptomatic children are unlikely to be tested.”
Of the symptomatic children, “5% had dyspnea or hypoxemia (a substantially lower percentage than what has been reported for adults) and 0.6% progressed to acute respiratory distress syndrome (ARDS) or multiorgan system dysfunction”; this also is at a lower rate than seen in adults, they said.
Very young children –infants or children in preschool – were more likely to have severe clinical manifestations than children who were older.
Thus, it appears that certain subpopulations of children are at increased risk for more significant COVID-19 illness: “younger age, underlying pulmonary pathology, and immunocompromising conditions,” Dr. Cruz and Dr. Zeichner suggested.
The two editorialists said the findings suggest children “may play a major role in community-based viral transmission.” Evidence suggests that children may have more upper respiratory tract involvement and that fecal shedding may occur for several weeks after diagnosis; this raises concerns about fecal-oral transmission, particularly for infants and children, and about viral replication in the gastrointestinal tract, they said. This has substantial implications for community spread in day care centers, schools, and in the home.
A great deal has been learned about COVID-19 in a short time, but there still is much to learn about the effect of the virus on children, the impact of children on viral spread, and about possible vertical transmission, they said.
“Widespread availability of testing will allow for us to more accurately describe the spectrum of illness and may result in adjustment of the apparent morbidity and mortality rate as fewer ill individuals are diagnosed,” Dr. Cruz and Dr. Zeichner wrote, adding that “rigorously gauging the impact of COVID-19 on children will be important to accurately model the pandemic and to ensure that appropriate resources are allocated to children requiring care.”
They noted that understanding differences in children versus adults with COVID-19 “can yield important insights into disease pathogenesis, informing management and the development of therapeutics.”
