COVID-19

Physicians nationwide will be challenged by the “unwinding” of the federal public health emergency declared for the COVID-19 pandemic.

The Biden administration intends to end by May 11 certain COVID-19 emergency measures used to aid in the response to the pandemic, while many others will remain in place.

A separate declaration covers the Food and Drug Administration’s emergency use authorizations (EUAs) for COVID medicines and tests. That would not be affected by the May 11 deadline, the FDA said. In addition, Congress and state lawmakers have extended some COVID response measures.

The result is a patchwork of emergency COVID-19 measures with different end dates.

The American Medical Association and the American Academy of Family Physicians (AAFP) are assessing how best to advise their members about the end of the public health emergency.

Several waivers regarding copays and coverage and policies regarding controlled substances will expire, Claire Ernst, director of government affairs at the Medical Group Management Association, told this news organization.

The impact of the unwinding “will vary based on some factors, such as what state the practice resides in,” Ms. Ernst said. “Fortunately, Congress provided some predictability for practices by extending many of the telehealth waivers through the end of 2024.”

The AAFP told this news organization that it has joined several other groups in calling for the release of proposed Drug Enforcement Administration (DEA) regulations meant to permanently allow prescriptions of buprenorphine treatment for opioid use disorder via telehealth. The AAFP and other groups want to review these proposals and, if needed, urge the DEA to modify or finalize before there are any disruptions in access to medications for opioid use disorder.
 

Patients’ questions

Clinicians can expect to field patients’ questions about their insurance coverage and what they need to pay, said Nancy Foster, vice president for quality and patient safety policy at the American Hospital Association (AHA).

“Your doctor’s office, that clinic you typically get care at, that is the face of medicine to you,” Ms. Foster told this news organization. “Many doctors and their staff will be asked, ‘What’s happening with Medicaid?’ ‘What about my Medicare coverage?’ ‘Can I still access care in the same way that I did before?’ ”

Physicians will need to be ready to answers those question, or point patients to where they can get answers, Ms. Foster said.

For example, Medicaid will no longer cover postpartum care for some enrollees after giving birth, said Taylor Platt, health policy manager for the American College of Obstetricians and Gynecologists.

The federal response to the pandemic created “a de facto postpartum coverage extension for Medicaid enrollees,” which will be lost in some states, Ms. Platt told this news organization. However, 28 states and the District of Columbia have taken separate measures to extend postpartum coverage to 1 year.

“This coverage has been critical for postpartum individuals to address health needs like substance use and mental health treatment and chronic conditions,” Ms. Platt said.

States significantly changed Medicaid policy to expand access to care during the pandemic.

All 50 states and the District of Columbia, for example, expanded coverage or access to telehealth services in Medicaid during the pandemic, according to a Jan. 31 report from the Kaiser Family Foundation (KFF). These expansions expire under various deadlines, although most states have made or are planning to make some Medicaid telehealth flexibilities permanent, KFF said.

The KFF report notes that all states and the District of Columbia temporarily waived some aspects of state licensure requirements, so that clinicians with equivalent licenses in other states could practice via telehealth.

In some states, these waivers are still active and are tied to the end of the federal emergency declaration. In others, they expired, with some states allowing for long-term or permanent interstate telemedicine, KFF said. (The Federation of State Medical Boards has a detailed summary of these modifications.)
 

The end of free COVID vaccines, testing for some patients

The AAFP has also raised concerns about continued access to COVID-19 vaccines, particularly for uninsured adults. Ashish Jha, MD, MPH, the White House COVID-19 Response Coordinator, said in a tweet that this transition, however, wouldn’t happen until a few months after the public health emergency ends.

After those few months, there will be a transition from U.S. government–distributed vaccines and treatments to ones purchased through the regular health care system, the “way we do for every other vaccine and treatment,” Dr. Jha added.

But that raises the same kind of difficult questions that permeate U.S. health care, with a potential to keep COVID active, said Patricia Jackson, RN, president of the Association for Professionals in Infection Control and Epidemiology (APIC).

People who don’t have insurance may lose access to COVID testing and vaccines.

“Will that lead to increases in transmission? Who knows,” Ms. Jackson told this news organization. “We will have to see. There are some health equity issues that potentially arise.”
 

Future FDA actions

Biden’s May 11 deadline applies to emergency provisions made under a Section 319 declaration, which allow the Department of Health and Human Services to respond to crises.

But a separate flexibility, known as a Section 564 declaration, covers the FDA’s EUAs, which can remain in effect even as the other declarations end.

The best-known EUAs for the pandemic were used to bring COVID vaccines and treatments to market. Many of these have since been converted to normal approvals as companies presented more evidence to support the initial emergency approvals. In other cases, EUAs have been withdrawn owing to disappointing research results, changing virus strains, and evolving medical treatments.

The FDA also used many EUAs to cover new uses of ventilators and other hospital equipment and expand these supplies in response to the pandemic, said Mark Howell, AHA’s director of policy and patient safety.

The FDA should examine the EUAs issued during the pandemic to see what greater flexibilities might be used to deal with future serious shortages of critical supplies. International incidents such as the war in Ukraine show how fragile the supply chain can be. The FDA should consider its recent experience with EUAs to address this, Mr. Howell said.

“What do we do coming out of the pandemic? And how do we think about being more proactive in this space to ensure that our supply doesn’t bottleneck, that we continue to make sure that providers have access to supply that’s not only safe and effective, but that they can use?” Mr. Howell told this news organization.

Such planning might also help prepare the country for the next pandemic, which is a near certainty, APIC’s Ms. Jackson said. The nation needs a nimbler response to the next major outbreak of an infectious disease, she said.

“There is going to be a next time,” Ms. Jackson said. “We are going to have another pandemic.”

The rising national suicide rate is being driven by increases among younger people and among people of color, according to a new report. 

Significant increases in suicide occurred among Native American, Black and Hispanic people, with a startling rise among young Black people. Meanwhile, the rate of suicide among older people declined between 2018 and 2021, the Centers for Disease Control and Prevention has reported.

In 2021, 48,183 people died by suicide in the United States, which equates to a suicide rate of 14.1 per 100,000 people. That level equals the 2018 suicide rate, which had seen a peak that was followed by declines associated with the pandemic.

Experts said rebounding suicide rates are common following times of crisis, such as the COVID-19 pandemic. Suicide declines have also occurred during times of war and natural disaster, when psychological resilience tends to increase and people work together to overcome shared adversity.

“That will wane, and then you will see rebounding in suicide rates. That is, in fact, what we feared would happen. And it has happened, at least in 2021,” Christine Moutier, MD, chief medical officer of the American Foundation for Suicide Prevention, told the New York Times.

The new CDC report found that the largest increase was among Black people aged 10-24 years, who experienced a 36.6% increase in suicide rate between 2018 and 2021. While Black people experience mental illness at the same rates as that of the general population, historically they have disproportionately limited access to mental health care, according to the American Psychiatric Association.

CDC report authors noted that some of the biggest increases in suicide rates occurred among groups most affected by the pandemic. 

From 2018 to 2021, the suicide rate for people aged 25-44 increased among Native Americans by 33.7% and among Black people by 22.9%. Suicide increased among multiracial people by 20.6% and among Hispanic or Latinx people by 19.4%. Among White people of all ages, the suicide rate declined or remained steady.

“As the nation continues to respond to the short- and long-term impacts of the COVID-19 pandemic, remaining vigilant in prevention efforts is critical, especially among disproportionately affected populations where longer-term impacts might compound preexisting inequities in suicide risk,” the CDC researchers wrote.

When 2022 began, we started seeing some light at the end of the COVID-19 tunnel. Vaccines were widely available, and even with new variants of the virus still occasionally emerging, the rates of severe morbidity and mortality appeared to be decreasing.

Expectedly, journals appeared to start moving more toward mainstream topics and publications rather than what seemed like a major focus on COVID-19 publications. The resulting literature was fantastic. This past year brought some outstanding publications related to emergency medicine that are practice changers.

Several of those topics were discussed in a prior Emergency Medicine Viewpoint from this news organization, and many more of the research advances of 2022 will be discussed in the near future. However, in this Viewpoint, I would like to present my annual review of my three “must-read” articles of the past year.

As in past years, I am choosing reviews of the literature rather than original research articles (which, all too often, become outdated or debunked within a few years). I choose these articles in the hopes that readers will not simply settle for my brief reviews of the key points but instead will feel compelled to download and read the entire articles. These publications address common conditions and quandaries we face in the daily practice of emergency medicine and are practice-changing.
 

Myocardial dysfunction after cardiac arrest: Tips and pitfalls

The management of post–cardiac arrest patients remains a hot topic in the resuscitation literature as we continue to understand that the immediate post-arrest period is critical to patient outcome.

Ortuno and colleagues reviewed the current literature on post-arrest care and wrote an outstanding summary of how to optimally care for these patients. More specifically, they focused on post-arrest patients who demonstrate continued shock, or “post–cardiac arrest myocardial dysfunction” (PCAMD).

They propose three mechanisms for the pathogenesis of PCAMD: ischemia reperfusion phenomenon, systemic inflammatory response, and increased catecholamine release

I will skip through the details of the pathophysiology that they describe in the article, but I certainly do recommend that everyone review their descriptions.

Management of these patients begins with a good hemodynamic assessment, which includes clinical markers of perfusion (blood pressure, capillary refill), ECG, and point-of-care ultrasound (POCUS). If the initial assessment reveals an obvious cause of the cardiac arrest (e.g., massive pulmonary embolism, myocardial infarction, pericardial tamponade), then the underlying cause should be treated expeditiously.

In the absence of an obvious treatable cause of the shock, the fluid status and cardiac function should be addressed with POCUS. If the patient is hypovolemic, intravenous fluids should be administered. If the fluid status is adequate, POCUS should be used to estimate the patient’s ventricular function. If the ventricle appears to be hyperdynamic with good contractility, shock should be treated with norepinephrine. On the other hand, if the ventricle is hypodynamic, dobutamine should be substituted for norepinephrine or, more often, added to norepinephrine.

The above represents a simplified summary of the critical points, but the authors do delve into further detail and also discuss some other options for therapies, including steroids, coronary revascularization, extracorporeal membrane oxygenation, and so on. The review is very thoughtful, thorough, and definitely worth a full read.
 

Top myths of diagnosis and management of infectious diseases in hospital medicine

Most, if not all of us in medicine, have heard the saying that 50% of what we learn in medical school (or residency) will turn out to be wrong. I certainly believe in this concept and consequently, like many of you, I enjoy reading about myths and misconceptions that we have been taught. With that in mind, I have to say that I love this article because it seems to have been written specifically to address what I was taught!

This author group, consisting mostly of clinical PharmDs who are experts in antibiotic use, provide us with an evidence-based discussion of myths and pitfalls in how antibiotics are often used in current clinical practice. The authors review their top 10 myths involving the use of antibiotics in treating infections in the hospital setting. A few of these relate more to the inpatient setting, but here are my favorite emergency department (ED)–related myths that they address:

• “Antibiotics do no harm.” The authors address the risk-benefit of antibiotics based on assumed vs. confirmed infections, including a brief discussion of adverse drug effects.
• “Antibiotic durations of 7, 14, or 21 days are typically necessary.” The authors address appropriate duration of antibiotic use and the fact that unnecessarily long durations of use can lead to resistance. They also provide reassurance that some infections can be treated with quite short durations of antibiotics.
• “If one drug is good, two (or more!) is better.” The use of multiple antibiotics, often with overlapping bacterial coverage, is rampant in medicine and further increases the risk for adverse drug effects and resistance.
• “Oral antibiotics are not as good as intravenous antibiotics for hospitalized patients.” This is definitely a myth that I learned. I recall being taught by many senior physicians that anyone sick enough for admission should be treated with intravenous antibiotics. As it turns out, absorption and effectiveness of most oral antibiotics is just as good as intravenous antibiotics, and the oral formulations are often safer.
• “A history of a penicillin allergy means the patient can never receive a beta-lactam antibiotic.” This is a myth that was debunked quite a few years ago, but it seems that many clinicians still need a reminder.

The authors included five more myths that are worth the read. This is an article that needs to be disseminated among all hospital clinicians.
 

Guidelines for low-risk, recurrent abdominal pain in the emergency department

The Society for Academic Emergency Medicine (SAEM) recently initiated a program focused on creating evidence-based approaches to challenging chief complaints and presentations in the emergency department (ED). In 2021, they published an approach to managing patients with recurrent, low-risk chest pain in the ED. This past year, they published their second guideline, focused on the management of patients with low-risk, recurrent abdominal pain in the ED.

Recurrent low-risk abdominal pain is a common and vexing presentation to EDs around the world, and there is little prior published guidance. Do all of these patients need repeat imaging? How do we manage their pain? Are there nonabdominal conditions that should be considered?

Broder and colleagues did a fantastic review of the current literature and, on behalf of SAEM, have provided a rational approach to optimal management of these patients. The four major questions they addressed, with brief summaries of their recommendations, are:

• Should adult ED patients with low-risk, recurrent and previously undifferentiated abdominal pain receive a repeat CT abdomen-pelvis (CTAP) after a negative CTAP within the past 12 months? This is a typical question that we all ponder when managing these patients. Unfortunately, the writing group found insufficient evidence to definitively identify populations in whom CTAP was recommended vs could be safely withheld. It is a bit disappointing that there is no definite answer to the question. On the other hand, it is reassuring to know that the world’s best evidence essentially says that it is perfectly appropriate to use your own good clinical judgment.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain with a negative CTAP receive additional imaging with abdominal ultrasound? In this case, the writing group found enough evidence, though low-level, to suggest against routine ultrasound in the absence of concern specifically for pelvic or hepatobiliary pathology. Like most tests, ultrasound is best used when there are specific concerns rather than being used in an undifferentiated fashion.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain receive screening for depression/anxiety? The writing group found enough evidence, though low-level again, to suggest that screening for depression and/or anxiety be performed during the ED evaluation. This could lead to successful therapy for the abdominal pain.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain receive nonopioid and/or nonpharmacologic analgesics? The writing group found little evidence to suggest for or against these analgesics, but they made a consensus recommendation suggesting an opioid-minimizing strategy for pain control.

Although the final recommendations of the writing group were not definitive or based on the strongest level of evidence, I find it helpful to have this guidance, nevertheless, on behalf of a major national organization. I also find it helpful to know that even with the best evidence available, optimal patient care will often boil down to physician experience and gestalt. I should also add that the overall article is chock-full of pearls and helpful information that will further inform the readers’ decisions, and so the full version is definitely worth the read.
 

In summary

There you have it – my three favorite practice-changing articles of 2022. Although I have tried to provide key points here, the full discussions of those key points in the published articles will provide a great deal more education than I can offer in this brief write-up, and so I strongly encourage everyone to read the full versions. Please be sure to include in the comments section your own pick for favorite or must-read articles from the past year.

When 2022 began, we started seeing some light at the end of the COVID-19 tunnel. Vaccines were widely available, and even with new variants of the virus still occasionally emerging, the rates of severe morbidity and mortality appeared to be decreasing.

Expectedly, journals appeared to start moving more toward mainstream topics and publications rather than what seemed like a major focus on COVID-19 publications. The resulting literature was fantastic. This past year brought some outstanding publications related to emergency medicine that are practice changers.

Several of those topics were discussed in a prior Emergency Medicine Viewpoint from this news organization, and many more of the research advances of 2022 will be discussed in the near future. However, in this Viewpoint, I would like to present my annual review of my three “must-read” articles of the past year.

As in past years, I am choosing reviews of the literature rather than original research articles (which, all too often, become outdated or debunked within a few years). I choose these articles in the hopes that readers will not simply settle for my brief reviews of the key points but instead will feel compelled to download and read the entire articles. These publications address common conditions and quandaries we face in the daily practice of emergency medicine and are practice-changing.
 

Myocardial dysfunction after cardiac arrest: Tips and pitfalls

The management of post–cardiac arrest patients remains a hot topic in the resuscitation literature as we continue to understand that the immediate post-arrest period is critical to patient outcome.

Ortuno and colleagues reviewed the current literature on post-arrest care and wrote an outstanding summary of how to optimally care for these patients. More specifically, they focused on post-arrest patients who demonstrate continued shock, or “post–cardiac arrest myocardial dysfunction” (PCAMD).

They propose three mechanisms for the pathogenesis of PCAMD: ischemia reperfusion phenomenon, systemic inflammatory response, and increased catecholamine release

I will skip through the details of the pathophysiology that they describe in the article, but I certainly do recommend that everyone review their descriptions.

Management of these patients begins with a good hemodynamic assessment, which includes clinical markers of perfusion (blood pressure, capillary refill), ECG, and point-of-care ultrasound (POCUS). If the initial assessment reveals an obvious cause of the cardiac arrest (e.g., massive pulmonary embolism, myocardial infarction, pericardial tamponade), then the underlying cause should be treated expeditiously.

In the absence of an obvious treatable cause of the shock, the fluid status and cardiac function should be addressed with POCUS. If the patient is hypovolemic, intravenous fluids should be administered. If the fluid status is adequate, POCUS should be used to estimate the patient’s ventricular function. If the ventricle appears to be hyperdynamic with good contractility, shock should be treated with norepinephrine. On the other hand, if the ventricle is hypodynamic, dobutamine should be substituted for norepinephrine or, more often, added to norepinephrine.

The above represents a simplified summary of the critical points, but the authors do delve into further detail and also discuss some other options for therapies, including steroids, coronary revascularization, extracorporeal membrane oxygenation, and so on. The review is very thoughtful, thorough, and definitely worth a full read.
 

Top myths of diagnosis and management of infectious diseases in hospital medicine

Most, if not all of us in medicine, have heard the saying that 50% of what we learn in medical school (or residency) will turn out to be wrong. I certainly believe in this concept and consequently, like many of you, I enjoy reading about myths and misconceptions that we have been taught. With that in mind, I have to say that I love this article because it seems to have been written specifically to address what I was taught!

This author group, consisting mostly of clinical PharmDs who are experts in antibiotic use, provide us with an evidence-based discussion of myths and pitfalls in how antibiotics are often used in current clinical practice. The authors review their top 10 myths involving the use of antibiotics in treating infections in the hospital setting. A few of these relate more to the inpatient setting, but here are my favorite emergency department (ED)–related myths that they address:

• “Antibiotics do no harm.” The authors address the risk-benefit of antibiotics based on assumed vs. confirmed infections, including a brief discussion of adverse drug effects.
• “Antibiotic durations of 7, 14, or 21 days are typically necessary.” The authors address appropriate duration of antibiotic use and the fact that unnecessarily long durations of use can lead to resistance. They also provide reassurance that some infections can be treated with quite short durations of antibiotics.
• “If one drug is good, two (or more!) is better.” The use of multiple antibiotics, often with overlapping bacterial coverage, is rampant in medicine and further increases the risk for adverse drug effects and resistance.
• “Oral antibiotics are not as good as intravenous antibiotics for hospitalized patients.” This is definitely a myth that I learned. I recall being taught by many senior physicians that anyone sick enough for admission should be treated with intravenous antibiotics. As it turns out, absorption and effectiveness of most oral antibiotics is just as good as intravenous antibiotics, and the oral formulations are often safer.
• “A history of a penicillin allergy means the patient can never receive a beta-lactam antibiotic.” This is a myth that was debunked quite a few years ago, but it seems that many clinicians still need a reminder.

The authors included five more myths that are worth the read. This is an article that needs to be disseminated among all hospital clinicians.
 

Guidelines for low-risk, recurrent abdominal pain in the emergency department

The Society for Academic Emergency Medicine (SAEM) recently initiated a program focused on creating evidence-based approaches to challenging chief complaints and presentations in the emergency department (ED). In 2021, they published an approach to managing patients with recurrent, low-risk chest pain in the ED. This past year, they published their second guideline, focused on the management of patients with low-risk, recurrent abdominal pain in the ED.

Recurrent low-risk abdominal pain is a common and vexing presentation to EDs around the world, and there is little prior published guidance. Do all of these patients need repeat imaging? How do we manage their pain? Are there nonabdominal conditions that should be considered?

Broder and colleagues did a fantastic review of the current literature and, on behalf of SAEM, have provided a rational approach to optimal management of these patients. The four major questions they addressed, with brief summaries of their recommendations, are:

• Should adult ED patients with low-risk, recurrent and previously undifferentiated abdominal pain receive a repeat CT abdomen-pelvis (CTAP) after a negative CTAP within the past 12 months? This is a typical question that we all ponder when managing these patients. Unfortunately, the writing group found insufficient evidence to definitively identify populations in whom CTAP was recommended vs could be safely withheld. It is a bit disappointing that there is no definite answer to the question. On the other hand, it is reassuring to know that the world’s best evidence essentially says that it is perfectly appropriate to use your own good clinical judgment.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain with a negative CTAP receive additional imaging with abdominal ultrasound? In this case, the writing group found enough evidence, though low-level, to suggest against routine ultrasound in the absence of concern specifically for pelvic or hepatobiliary pathology. Like most tests, ultrasound is best used when there are specific concerns rather than being used in an undifferentiated fashion.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain receive screening for depression/anxiety? The writing group found enough evidence, though low-level again, to suggest that screening for depression and/or anxiety be performed during the ED evaluation. This could lead to successful therapy for the abdominal pain.
• Should adult ED patients with low-risk, recurrent, and previously undifferentiated abdominal pain receive nonopioid and/or nonpharmacologic analgesics? The writing group found little evidence to suggest for or against these analgesics, but they made a consensus recommendation suggesting an opioid-minimizing strategy for pain control.

Although the final recommendations of the writing group were not definitive or based on the strongest level of evidence, I find it helpful to have this guidance, nevertheless, on behalf of a major national organization. I also find it helpful to know that even with the best evidence available, optimal patient care will often boil down to physician experience and gestalt. I should also add that the overall article is chock-full of pearls and helpful information that will further inform the readers’ decisions, and so the full version is definitely worth the read.

Hello. I’m Dr Sandra Fryhofer. Welcome to Medicine Matters. The topic is highlights from ACIP’s new adult schedule for 2023, published in the Annals of Internal Medicine, and why this new schedule may be a collector’s item.

It’s a new year, which means a new ACIP adult immunization schedule – a valuable resource collating ACIP’s most up-to-date vaccination recommendations.

Here are this year’s five most important changes:

• COVID vaccines now front and center
• New emphasis on polio vaccination
• Inclusion of some nonvaccine products (such as monoclonal antibody products)
• Pharmacists group has approved the schedule for the first time
• New shared clinical decision-making option for pneumococcal vaccines

The schedule’s organization remains the same. It still has four sections:

• Table 1: vaccinations by age
• Table 2: vaccinations by medical condition and other indications
• The Notes section (alphabetically ordered by vaccine type)
• Appendix listing of vaccine-specific contraindications and precautions

But what’s unique this year is that some of the abbreviations have historical implications. The first change is no big surprise in light of what we’ve gone through in the past few years. COVID vaccines are listed first on the cover page by brand name for those authorized and by company name for those still under US emergency use authorization. They’re also listed first on the graphics and in the notes.

COVID and mRNA and protein-based vaccines have now been assigned official abbreviations based on vaccine platform and valency.

• 1vCOV-mRNA: Comirnaty/Pfizer-BioNTech and Spikevax Moderna COVID-19 vaccines
• 2vCOV-mRNA: Pfizer-BioNTech and Moderna bivalent COVID-19 vaccines
• 1vCOV-aPS: Novavax COVID-19 vaccine

Also remarkable is the absence of COVID viral vector vaccines on the list. However, the viral vector COVID vaccine (which has been available but is not preferred) does have a CDC website link in the Notes section.

A sad but necessary inclusion was triggered by recent polio cases in New York. Polio was believed to be eradicated, and we thought adults no longer needed to be vaccinated against polio. In the new schedule, the polio vaccine is listed on the cover page but is not included in the tables. Current polio vaccination recommendations are now in the Notes section.

Also of historical significance and something that may set a precedent is the inclusion of nonvaccine products. The value of COVID preexposure prophylaxis with products including monoclonal antibodies (such as Evusheld) for people who are moderately or severely immunocompromised is mentioned in the Notes section.

For the first time ever, the schedule has been approved by the American Pharmacists Association, which validates pharmacists as established partners in vaccine administration.
 

Color-code key

One aspect of the schedule that has not changed is the color-code key:

• Yellow: Recommended if the patient meets the age requirement
• Purple: Indicated for those with additional risk factors or another indication
• Blue: Recommended based on shared clinical decision-making
• Orange: Precaution
• Red: Contraindicated or not recommended; the vaccine should not be administered. Overlays on the red more precisely clarify whether a vaccine is really contraindicated or just not recommended. An asterisk on red means vaccinate after pregnancy if indicated.
• Gray: No recommendation or not applicable

Vaccinations by age

Table 1 lists recommended vaccinations by age. There is one major change. COVID vaccines are on the first row of the graphic, with the need for both a primary series and boosters emphasized on the overlay. The notes have hyperlinks to the most up-to-date COVID vaccination recommendations.

Pneumococcal vaccination. Pneumococcal vaccination is routinely recommended starting at age 65. Current recommendations for those not previously vaccinated have not changed since last year. But on Table 1, the bottom half of the row for those 65 or older is now blue (and that’s new). This new color blue means shared clinical decision-making and applies to people who were previously considered fully vaccinated with the now extinct combination of PCV13 and PPSV23. These patients now have the option of getting a dose of PCV20 five years after completing their PCV13-PPSV23 combo series. This option is blue because the decision is up to you and your patient.

Check the notes for more pneumococcal vaccination details. For example, for those partially vaccinated using lower valency vaccines, there’s an option of substituting PCV20 for PPSV23 to broaden and increase durability of protection.

The pneumococcal vaccination recommendation options are complicated. A new pneumococcal vaccination app can help.

Hepatitis B. For adults under age 60, the color code for the hepatitis B vaccine is yellow, meaning it’s indicated for all. For older patients, the color code is purple. If a patient who is age 60 or older wants the hepatitis B vaccine, they can have it even in the absence of additional risk indications.
 

Vaccinations by medical condition or other indications

Other than a few minor word changes on the overlay, the only thing that’s new is the COVID vaccine row.

This table is helpful for matching vaccine recommendations with specific medical conditions, including pregnancy, immunocompromise, HIV (with specifics according to CD4 count), asplenia, complement deficiencies, heart disease, lung disease, alcoholism, chronic liver disease, diabetes, health care personnel, and men who have sex with men.

Use this table to dot the i’s and cross the t’s when it comes to vaccination recommendations. For example, take a look at the pregnancy column. Live virus vaccines, including LAIV, MMR, and varicella, are contraindicated and color-coded red. MMR and varicella also have an asterisk, meaning vaccinate after pregnancy if indicated. HPV vaccines are not live virus vaccines, but the overlay says they are not recommended during pregnancy. The asterisk indicates that you can vaccinate after pregnancy.
 

Vaccine notes

The notes are in alphabetical order, and their organization (routine, special situations, and shared clinical decision-making when indicated) has not changed. They are concise and succinct, but sometimes they’re not enough. That’s why vaccine-specific links to more complete recommendations are so convenient.

Notes for hepatitis B contain nuances on specific dosing for vaccinating patients on dialysis, as well as a reminder that newer hepatitis C vaccines such as Heplisav and PreHevbrio are not recommended during pregnancy due to lack of safety data.

For influenza, everyone 6 months or older still needs yearly flu vaccination with an age- and health-appropriate flu vaccine. But for those aged 65 or older, the notes specify the three vaccine versions now preferred: high-dose, recombinant, or adjuvanted versions. However, if these aren’t available, it’s better to get any flu vaccine than to go without.

Under meningococcal vaccines, the notes for MenACWY and MenB are combined. For MenB, trade names Bexsero and Trumenba are specified because the products are not interchangeable. Booster intervals for those still at risk are different for each vaccine type: every 5 years for MenACWY boosters, and every 2-3 years for boosts of MenB.

The recent polio cases in New York have put polio vaccination in the spotlight. ACIP has now reinstated its Polio Vaccine Work Group. The new schedule lists polio vaccines on the cover page. Current recommendations have been added to the notes section. Routine vaccination for adults is not necessary, at least for now. However, those at increased risk for exposure to polio fall in the special-situation category. For those at increased risk who have completed a polio vaccine series, a single lifetime IPV booster can be given. For those at increased risk who have not completed their polio vaccine series, now would be the time to finish the series.
 

Appendix

The final step in using the new schedule is checking the appendix and its list of vaccine-specific contraindications and precautions.

I hope this review of the new ACIP adult immunization schedule has been helpful. For Medicine Matters, I’m Dr. Sandra Fryhofer.

Hello. I’m Dr Sandra Fryhofer. Welcome to Medicine Matters. The topic is highlights from ACIP’s new adult schedule for 2023, published in the Annals of Internal Medicine, and why this new schedule may be a collector’s item.

It’s a new year, which means a new ACIP adult immunization schedule – a valuable resource collating ACIP’s most up-to-date vaccination recommendations.

Here are this year’s five most important changes:

• COVID vaccines now front and center
• New emphasis on polio vaccination
• Inclusion of some nonvaccine products (such as monoclonal antibody products)
• Pharmacists group has approved the schedule for the first time
• New shared clinical decision-making option for pneumococcal vaccines

The schedule’s organization remains the same. It still has four sections:

• Table 1: vaccinations by age
• Table 2: vaccinations by medical condition and other indications
• The Notes section (alphabetically ordered by vaccine type)
• Appendix listing of vaccine-specific contraindications and precautions

But what’s unique this year is that some of the abbreviations have historical implications. The first change is no big surprise in light of what we’ve gone through in the past few years. COVID vaccines are listed first on the cover page by brand name for those authorized and by company name for those still under US emergency use authorization. They’re also listed first on the graphics and in the notes.

COVID and mRNA and protein-based vaccines have now been assigned official abbreviations based on vaccine platform and valency.

• 1vCOV-mRNA: Comirnaty/Pfizer-BioNTech and Spikevax Moderna COVID-19 vaccines
• 2vCOV-mRNA: Pfizer-BioNTech and Moderna bivalent COVID-19 vaccines
• 1vCOV-aPS: Novavax COVID-19 vaccine

Also remarkable is the absence of COVID viral vector vaccines on the list. However, the viral vector COVID vaccine (which has been available but is not preferred) does have a CDC website link in the Notes section.

A sad but necessary inclusion was triggered by recent polio cases in New York. Polio was believed to be eradicated, and we thought adults no longer needed to be vaccinated against polio. In the new schedule, the polio vaccine is listed on the cover page but is not included in the tables. Current polio vaccination recommendations are now in the Notes section.

Also of historical significance and something that may set a precedent is the inclusion of nonvaccine products. The value of COVID preexposure prophylaxis with products including monoclonal antibodies (such as Evusheld) for people who are moderately or severely immunocompromised is mentioned in the Notes section.

For the first time ever, the schedule has been approved by the American Pharmacists Association, which validates pharmacists as established partners in vaccine administration.
 

Color-code key

One aspect of the schedule that has not changed is the color-code key:

• Yellow: Recommended if the patient meets the age requirement
• Purple: Indicated for those with additional risk factors or another indication
• Blue: Recommended based on shared clinical decision-making
• Orange: Precaution
• Red: Contraindicated or not recommended; the vaccine should not be administered. Overlays on the red more precisely clarify whether a vaccine is really contraindicated or just not recommended. An asterisk on red means vaccinate after pregnancy if indicated.
• Gray: No recommendation or not applicable

Vaccinations by age

Table 1 lists recommended vaccinations by age. There is one major change. COVID vaccines are on the first row of the graphic, with the need for both a primary series and boosters emphasized on the overlay. The notes have hyperlinks to the most up-to-date COVID vaccination recommendations.

Pneumococcal vaccination. Pneumococcal vaccination is routinely recommended starting at age 65. Current recommendations for those not previously vaccinated have not changed since last year. But on Table 1, the bottom half of the row for those 65 or older is now blue (and that’s new). This new color blue means shared clinical decision-making and applies to people who were previously considered fully vaccinated with the now extinct combination of PCV13 and PPSV23. These patients now have the option of getting a dose of PCV20 five years after completing their PCV13-PPSV23 combo series. This option is blue because the decision is up to you and your patient.

Check the notes for more pneumococcal vaccination details. For example, for those partially vaccinated using lower valency vaccines, there’s an option of substituting PCV20 for PPSV23 to broaden and increase durability of protection.

The pneumococcal vaccination recommendation options are complicated. A new pneumococcal vaccination app can help.

Hepatitis B. For adults under age 60, the color code for the hepatitis B vaccine is yellow, meaning it’s indicated for all. For older patients, the color code is purple. If a patient who is age 60 or older wants the hepatitis B vaccine, they can have it even in the absence of additional risk indications.
 

Vaccinations by medical condition or other indications

Other than a few minor word changes on the overlay, the only thing that’s new is the COVID vaccine row.

This table is helpful for matching vaccine recommendations with specific medical conditions, including pregnancy, immunocompromise, HIV (with specifics according to CD4 count), asplenia, complement deficiencies, heart disease, lung disease, alcoholism, chronic liver disease, diabetes, health care personnel, and men who have sex with men.

Use this table to dot the i’s and cross the t’s when it comes to vaccination recommendations. For example, take a look at the pregnancy column. Live virus vaccines, including LAIV, MMR, and varicella, are contraindicated and color-coded red. MMR and varicella also have an asterisk, meaning vaccinate after pregnancy if indicated. HPV vaccines are not live virus vaccines, but the overlay says they are not recommended during pregnancy. The asterisk indicates that you can vaccinate after pregnancy.
 

Vaccine notes

The notes are in alphabetical order, and their organization (routine, special situations, and shared clinical decision-making when indicated) has not changed. They are concise and succinct, but sometimes they’re not enough. That’s why vaccine-specific links to more complete recommendations are so convenient.

Notes for hepatitis B contain nuances on specific dosing for vaccinating patients on dialysis, as well as a reminder that newer hepatitis C vaccines such as Heplisav and PreHevbrio are not recommended during pregnancy due to lack of safety data.

For influenza, everyone 6 months or older still needs yearly flu vaccination with an age- and health-appropriate flu vaccine. But for those aged 65 or older, the notes specify the three vaccine versions now preferred: high-dose, recombinant, or adjuvanted versions. However, if these aren’t available, it’s better to get any flu vaccine than to go without.

Under meningococcal vaccines, the notes for MenACWY and MenB are combined. For MenB, trade names Bexsero and Trumenba are specified because the products are not interchangeable. Booster intervals for those still at risk are different for each vaccine type: every 5 years for MenACWY boosters, and every 2-3 years for boosts of MenB.

The recent polio cases in New York have put polio vaccination in the spotlight. ACIP has now reinstated its Polio Vaccine Work Group. The new schedule lists polio vaccines on the cover page. Current recommendations have been added to the notes section. Routine vaccination for adults is not necessary, at least for now. However, those at increased risk for exposure to polio fall in the special-situation category. For those at increased risk who have completed a polio vaccine series, a single lifetime IPV booster can be given. For those at increased risk who have not completed their polio vaccine series, now would be the time to finish the series.
 

Appendix

The final step in using the new schedule is checking the appendix and its list of vaccine-specific contraindications and precautions.

Maternal vaccination with two doses of the mRNA COVID-19 vaccine was 95% effective against infant infection from the delta variant, and 45% effective against infant infection from the omicron variant, a new study shows.

Previous research has confirmed that COVID-19 neutralizing antibodies following maternal vaccination or maternal COVID-19 infection are present in umbilical cord blood, breast milk, and infant serum specimens, wrote Sarah C.J. Jorgensen, PharmD, MPH, of the University of Toronto, and colleagues in their article published in The BMJ.

In the study, the researchers identified maternal and newborn pairs using administrative databases from Canada. The study population included 8,809 infants aged younger than 6 months who were born between May 7, 2021, and March 31, 2022, and who underwent testing for COVID-19 between May 7, 2021, and September 5, 2022.

Maternal vaccination with the primary COVID-19 mRNA monovalent vaccine series was defined as two vaccine doses administered up to 14 days before delivery, with at least one of the doses after the conception date.

Maternal vaccination with the primary series plus one booster was defined as three doses administered up to 14 days before delivery, with at least one of these doses after the conception date.

The primary outcome was the presence of delta or omicron COVID-19 infection or hospital admission of the infants.

The study population included 99 COVID-19 cases with the delta variant (with 4,365 controls) and 1,501 cases with the omicron variant (with 4,847 controls).

Overall, the vaccine effectiveness of maternal doses was 95% against delta infection and 45% against omicron.

The effectiveness against hospital admission in cases of delta and omicron variants were 97% and 53%, respectively.

The effectiveness of three doses was 73% against omicron infant infection and 80% against omicron-related infant hospitalization. Data were not available for the effectiveness of three doses against the delta variant.

The effectiveness of two doses of vaccine against infant omicron infection was highest when mothers received the second dose during the third trimester of pregnancy, compared with during the first trimester or second trimester (53% vs. 47% and 53% vs. 37%, respectively).

Vaccine effectiveness with two doses against infant infection from omicron was highest in the first 8 weeks of life (57%), then decreased to 40% among infants after 16 weeks of age.

Although the study was not designed to assess the mechanism of action of the impact of maternal vaccination on infants, the current study results were consistent with other recent studies showing a reduction in infections and hospitalizations among infants whose mothers received COVID-19 vaccines during pregnancy, the researchers wrote in their discussion.

The findings were limited by several factors including the potential unmeasured confounders not available in databases, such as whether infants were breastfed, the researchers noted. Other limitations included a lack of data on home test results and the inability to assess the waning impact of the vaccine effectiveness against the delta variant because of the small number of delta cases, they said. However, the results suggest that the mRNA COVID-19 vaccine during pregnancy was moderately to highly effective for protection against omicron and delta infection and infection-related hospitalization – especially during the first 8 weeks of life.

Effectiveness is encouraging, but updates are needed

The effectiveness of maternal vaccination to prevent COVID-19 infection and related hospitalizations in infants is promising, especially since those younger than 6 months have no other source of vaccine protection against COVID-19 infection, wrote Dana Danino, MD, of Soroka University Medical Center, Israel, and Ilan Youngster, MD, of Shamir Medical Center, Israel, in an accompanying editorial also published in The BMJ.

They also noted that maternal vaccination during pregnancy is an established method of protecting infants from infections such as influenza and pertussis.

Data from previous studies show that most infants whose mothers were vaccinated against COVID-19 during pregnancy retained maternal antibodies at 6 months, “but evidence for protection against neonatal COVID-19 infection has been deficient,” they said.

The current study findings support the value of vaccination during pregnancy, and the findings were strengthened by the large study population, the editorialists wrote. However, whether the same effectiveness holds for other COVID-19 strains such as BQ.1, BQ.1.1, BF.7, XBB, and XBB.1 remains unknown, they said.

Other areas in need of exploration include the optimal timing of vaccination during pregnancy, the protective effects of a bivalent mRNA vaccine (vs. the primary monovalent vaccine in the current study), and the potential benefits of additional boosters, they added.

“Although Jorgenson and colleagues’ study reinforces the value of maternal vaccination against COVID-19 during pregnancy, more studies are needed to better inform vaccination recommendations in an evolving landscape of new SARS-CoV-2 strains and novel vaccines,” the editorialists concluded.

The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-term Care; the study also received funding from the Canadian Immunization Research Network and the Public Health Agency of Canada. Dr. Jorgensen and the editorialists had no financial conflicts to disclose.

Among adults hospitalized for COVID-19, acute cardiac events are common, particularly among those with underlying heart disease, and are associated with more severe disease outcomes, a new study suggests.

“We expected to see acute cardiac events occurring among adults hospitalized with COVID-19 but were surprised by how frequently they occurred,” Rebecca C. Woodruff, PhD, MPH, of the U.S. Centers for Disease Control and Prevention, Atlanta, told this news organization.

Overall, she said, “about 1 in 10 adults experienced an acute cardiac event – including heart attacks and acute heart failure – while hospitalized with COVID-19, and this included people with no preexisting heart disease.”

However, she added, “about a quarter of those with underlying heart disease had an acute cardiac event. These patients tended to experience more severe disease outcomes relative to patients hospitalized with COVID-19 who did not experience an acute cardiac event.”

The findings might be relevant to hospitalizations for other viral diseases, “though we can’t say for sure,” she noted. “This study was modeled off a previous study conducted before the COVID-19 pandemic among adults hospitalized with influenza. About 11.7% of [those] adults experienced an acute cardiac event, which was a similar percentage as what we found among patients hospitalized with COVID-19.”

The study was published online in the Journal of the American College of Cardiology.
 

Underlying cardiac disease key

Dr. Woodruff and colleagues analyzed medical records on a probability sample of 8,460 adults hospitalized with SARS-CoV-2 infection identified from 99 U.S. counties in 14 U.S. states (about 10% of the United States population) from January to November 2021.

Among participants, 11.4% had an acute cardiac event during their hospitalization. The median age was 69 years; 56.5% were men; 48.7%, non-Hispanic White; 33.6%, non-Hispanic Black; 7.4%, Hispanic; and 7.1%, non-Hispanic Asian or Pacific Islander.

As indicated, the prevalence was higher among those with underlying cardiac disease (23.4%), compared with those without (6.2%).

Acute ischemic heart disease (5.5%) and acute heart failure (5.4%) were the most prevalent events; 0.3% of participants had acute myocarditis or pericarditis.

Risk factors varied, depending on underlying cardiac disease status. Those who experienced one or more acute cardiac events had a greater risk for intensive care unit admission (adjusted risk ratio,1.9) and in-hospital death (aRR, 1.7) versus those who did not.

In multivariable analyses, the risk of experiencing acute heart failure was significantly greater among men (aRR, 1.5) and among those with a history of congestive heart failure (aRR, 13.5), atrial fibrillation (aRR, 1.6) or hypertension (aRR,1.3).

Among patients who experienced one or more acute cardiac events, 39.2% required an intensive care unit stay for a median of 5 days. Approximately 22.4% required invasive mechanical ventilation or extracorporeal membrane oxygenation, and 21.1% died while hospitalized.

“Persons at greater risk for experiencing acute cardiac events during COVID-19–associated hospitalizations might benefit from more intensive clinical evaluation and monitoring during hospitalization,” the authors conclude.

The team currently is taking a closer look at acute myocarditis among patients hospitalized with COVID-19, Dr. Woodruff said. Preliminary results were presented at the 2022 annual scientific sessions of the American Heart Association and a paper is forthcoming.
 

Contemporary data needed

James A. de Lemos, MD, co-chair of the American Heart Association’s COVID-19 CVD Registry Steering Committee and professor of medicine at the University of Texas Southwestern Medical Center, Dallas, said the findings mirror his team’s clinical experience in 2020 and 2021 and echo what was seen in the AHA COVID registry: that is, a 0.3% rate of myocarditis.

“The major caveat is that [the findings] may not be generalizable to contemporary COVID infection, both due to changing viral variants and higher levels of immunity in the population,” he said.

“Rates of COVID hospitalization are markedly lower with the current dominant variants, and we would expect the cardiac risk to be lower as well. I would like to see more contemporary data with current variants, particularly focused on higher risk patients with cardiovascular disease,” Dr. de Lemos added.

In a related editorial, George A. Mensa, MD, of the National Heart, Lung, and Blood Institute in Bethesda, Md., and colleagues suggest that the broader impact of the COVID-19 pandemic on human health remains “incompletely examined.”

“The impact of COVID-19 on cardiovascular mortality, in particular, appears to have varied widely, with no large increases seen in a number of the most developed countries but marked increases in hypertensive heart disease mortality seen in the United States in 2021,” they conclude. “The potential contribution of COVID-19 to these deaths, either directly or indirectly, remains to be determined.”

No commercial funding or relevant financial relationships were reported.

James A. de Lemos, MD, co-chair of the American Heart Association’s COVID-19 CVD Registry Steering Committee and professor of medicine at the University of Texas Southwestern Medical Center, Dallas, said the findings mirror his team’s clinical experience in 2020 and 2021 and echo what was seen in the AHA COVID registry: that is, a 0.3% rate of myocarditis.

“The major caveat is that [the findings] may not be generalizable to contemporary COVID infection, both due to changing viral variants and higher levels of immunity in the population,” he said.

“Rates of COVID hospitalization are markedly lower with the current dominant variants, and we would expect the cardiac risk to be lower as well. I would like to see more contemporary data with current variants, particularly focused on higher risk patients with cardiovascular disease,” Dr. de Lemos added.

In a related editorial, George A. Mensa, MD, of the National Heart, Lung, and Blood Institute in Bethesda, Md., and colleagues suggest that the broader impact of the COVID-19 pandemic on human health remains “incompletely examined.”

“The impact of COVID-19 on cardiovascular mortality, in particular, appears to have varied widely, with no large increases seen in a number of the most developed countries but marked increases in hypertensive heart disease mortality seen in the United States in 2021,” they conclude. “The potential contribution of COVID-19 to these deaths, either directly or indirectly, remains to be determined.”

No commercial funding or relevant financial relationships were reported.

Among adults hospitalized for COVID-19, acute cardiac events are common, particularly among those with underlying heart disease, and are associated with more severe disease outcomes, a new study suggests.

“We expected to see acute cardiac events occurring among adults hospitalized with COVID-19 but were surprised by how frequently they occurred,” Rebecca C. Woodruff, PhD, MPH, of the U.S. Centers for Disease Control and Prevention, Atlanta, told this news organization.

Overall, she said, “about 1 in 10 adults experienced an acute cardiac event – including heart attacks and acute heart failure – while hospitalized with COVID-19, and this included people with no preexisting heart disease.”

However, she added, “about a quarter of those with underlying heart disease had an acute cardiac event. These patients tended to experience more severe disease outcomes relative to patients hospitalized with COVID-19 who did not experience an acute cardiac event.”

The findings might be relevant to hospitalizations for other viral diseases, “though we can’t say for sure,” she noted. “This study was modeled off a previous study conducted before the COVID-19 pandemic among adults hospitalized with influenza. About 11.7% of [those] adults experienced an acute cardiac event, which was a similar percentage as what we found among patients hospitalized with COVID-19.”

The study was published online in the Journal of the American College of Cardiology.
 

Underlying cardiac disease key

Dr. Woodruff and colleagues analyzed medical records on a probability sample of 8,460 adults hospitalized with SARS-CoV-2 infection identified from 99 U.S. counties in 14 U.S. states (about 10% of the United States population) from January to November 2021.

Among participants, 11.4% had an acute cardiac event during their hospitalization. The median age was 69 years; 56.5% were men; 48.7%, non-Hispanic White; 33.6%, non-Hispanic Black; 7.4%, Hispanic; and 7.1%, non-Hispanic Asian or Pacific Islander.

As indicated, the prevalence was higher among those with underlying cardiac disease (23.4%), compared with those without (6.2%).

Acute ischemic heart disease (5.5%) and acute heart failure (5.4%) were the most prevalent events; 0.3% of participants had acute myocarditis or pericarditis.

Risk factors varied, depending on underlying cardiac disease status. Those who experienced one or more acute cardiac events had a greater risk for intensive care unit admission (adjusted risk ratio,1.9) and in-hospital death (aRR, 1.7) versus those who did not.

In multivariable analyses, the risk of experiencing acute heart failure was significantly greater among men (aRR, 1.5) and among those with a history of congestive heart failure (aRR, 13.5), atrial fibrillation (aRR, 1.6) or hypertension (aRR,1.3).

Among patients who experienced one or more acute cardiac events, 39.2% required an intensive care unit stay for a median of 5 days. Approximately 22.4% required invasive mechanical ventilation or extracorporeal membrane oxygenation, and 21.1% died while hospitalized.

“Persons at greater risk for experiencing acute cardiac events during COVID-19–associated hospitalizations might benefit from more intensive clinical evaluation and monitoring during hospitalization,” the authors conclude.

While it’s well known that COVID-19 vaccines are less effective in patients with chronic lymphocytic leukemia (CLL) who take immunity-lowering drugs, a new study offers fresh insight into what’s happening inside the body. In these patients, the vaccines often don’t boost B cells, which produce antibodies, but they do strengthen T cells, potentially providing crucial protection against severe illness and death.

These findings don’t reveal whether the T-cell boost actually provides extra protection against COVID-19. Still, the study suggests that patients with CLL should be vaccinated no matter which medications they’re taking, coauthor and hematologist/oncologist Clemens-Martin Wendtner, MD, of the Munich (Germany) Clinic, said in an interview.

“Do not defer or pause treatment,” said Dr. Wendtner, whose study was published in Blood Advances.

Patients with CLL appear to have among the weakest responses to the COVID-19 vaccine among people with various types of blood cancer. A meta-analysis published in 2022 found that seropositivity rates following vaccination were just 51% in patients with CLL, compared with 80%-90% in those with acute leukemia and 76%-80% of those with myeloma.

“Usually, the response rate to vaccination among the nonimmunocompromised would be 95%,” Dr. Wendtner said.

Research has also suggested that patients treated with B-cell pathway inhibitors and anti-CD20 antibodies are especially likely to have poorer responses to COVID-19 vaccines, no surprise considering that their job is to dampen the immune system. But there’s an unanswered question, according to Dr. Wendtner: Does “just measuring B-cell response tell us everything about the immune response?”

The new prospective, single-institution study aims to answer that question in patients who each received two types of vaccines. Researchers compared peripheral blood mononuclear cell transcriptional response with antibody and T-cell response rates in 15 patients with CLL/small lymphocytic lymphoma following vaccination with both the Pfizer-BioNTech and AstraZeneca vaccines.

The average antibody response was limited. “Overall, 7/15 of patients failed to mount a humoral response even after three-dose vaccination,” the researchers reported. All of the patients were “heavily pretreated” with CLL medications such as venetoclax, an anti-CD20 monoclonal antibody.

By contrast, the T-cell response was much stronger: 80% of patients (12/15) had a robust response, a number that grew to 90% (14/15) after a booster. This response is “almost ideal” considering that the response in a nonimmunocompromised person would be about 99%, Dr. Wendtner said.

The study also revealed that vaccine responses were weaker in patients who took a combination of a Bruton tyrosine kinase inhibitor and venetoclax within a year.

Four patients developed COVID-19 infections with the Omicron variant about 6 months after vaccination. All had mild symptoms. A lone patient had a history of COVID-19 infection prior to vaccination.

The researchers noted that the study had several limitations, including its small size, its reliance on a single institution, and the differences in treatments and vaccination protocols among the patient population.

Broadly speaking, the study showed that “a vaccine is not in vain” in patients with CLL, “although the doctor might not detect an antibody response,” Dr. Wendtner said. He added that mixing vaccine types should provide more protection. Start with a viral vector vaccine followed by an mRNA vaccine or vice versa, he suggested.

In an interview, infectious disease physician Joshua A. Hill, MD, from Fred Hutchinson Cancer Center, Seattle, who wasn’t involved with the study, said it makes “important and interesting observations to reinforce other studies with similar findings.”

Specifically, Dr. Hill said, “despite the absence of a robust antibody response some of these patients who are on active treatment, patients can still generate robust cellular immune responses in the form of T-cell immunity. Our understanding is that having T cell immunity will provide important additional protection for developing severe disease, although is less easily tested.”

As for the best vaccination strategies, Dr. Hill said “patients should get vaccinated as soon as they are eligible, according to standard guidelines. If patients have not yet started therapy, they should get their indicated vaccines before starting treatment whenever possible.”

The German study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases and the Bavarian State Ministry of Science and Art. Dr. Wendtner disclosed consultant fees from AstraZeneca and BioNTech, and another author disclosed consultant fees from AstraZeneca. The other authors reported no disclosures. Dr. Hill disclosed consultant fees from Moderna, Pfizer, and Gilead.

New surveillance data from the Vaccine Adverse Event Reporting System (VAERS) back previous findings of increased risk for Guillain-Barré syndrome (GBS) after receiving the Janssen COVID-19 vaccine (Ad26.COV2.S).

Over 14 months, GBS reporting rates within 21 and 42 days of administration of Janssen’s replication-incompetent adenoviral vector vaccine were approximately 9 to 12 times higher than after administration of the Pfizer-BioNTech (BNT162b2) or the Moderna (mRNA-1273) mRNA COVID vaccines.

Additionally, observed GBS cases after the Janssen shot were 2 to 3 times greater than expected, based on background rates within 21 and 42 days of vaccination.

Conversely, and confirming prior data, there was no increased risk for GBS with the Pfizer or Moderna vaccines and no significant difference between observed and expected numbers of GBS cases after either mRNA COVID-19 vaccine.

The findings were published online  in JAMA Network Open.
 

More precise risk estimates

Winston Abara, MD, with the U.S. Centers for Disease Control and Prevention, and colleagues analyzed GBS reports submitted to the VAERS between December 2020 and January 2022. 

Among 487.6 million COVID-19 vaccine doses administered, 3.7% were Janssen’s Ad26.COV2.S vaccine, 54.7% were Pfizer’s BNT162b2 vaccine, and 41.6% were Moderna’s mRNA-1273 vaccine.

There were 295 verified reports of GBS identified after COVID-19 vaccination. Of these, 209 occurred within 21 days of vaccination and 253 within 42 days.

Within 21 days of vaccination, GBS reporting rates per 1 million doses were 3.29 for the Janssen vaccine versus 0.29 and 0.35 for the Pfizer and Moderna vaccines, respectively. Within 42 days of vaccination, reporting rates per 1 million doses were 4.07, 0.34, and 0.44, respectively.

Also within 21 days of vaccination, GBS reporting rates were significantly higher with the Janssen vaccine than the Pfizer vaccine (reporting rate ratio, 11.40) and the Moderna vaccine (RRR, 9.26). Similar findings were observed within 42 days after vaccination.

The observed-to-expected ratios were 3.79 for 21-day and 2.34 for 42-day intervals after receipt of the Janssen vaccine, and less than 1 (not significant) after the Pfizer or Moderna vaccine within both post-vaccination periods.

“Unlike prior studies, our analysis included all U.S. reports of verified GBS cases that met the Brighton Collaboration GBS case definition criteria (Brighton Levels 1, 2, and 3) submitted over a 14-month surveillance period to the to the Vaccine Adverse Event Reporting System,” Dr. Abara said in an interview. “Because we used all U.S. reports, the sample of verified GBS cases in this analysis is larger than other studies. Therefore, it may provide a more precise estimate of the GBS risk within 21 and 42 days after mRNA and Ad26.COV2.S vaccination,” he said.
 

‘Remarkably low’ use

Nicola Klein, MD, PhD, Kaiser Permanente Vaccine Study Center, Oakland, Calif., noted that this is a “nice confirmatory analysis that supports and further expands what’s been observed before.”

Last year, as reported by this news organization, Dr. Klein and colleagues reported data from the Vaccine Safety Datalink confirming a small but statistically significant increased risk for GBS in the 3 weeks after receipt of the Janssen COVID-19 vaccine but not the Pfizer or Moderna vaccines.

Unlike VAERS, the Vaccine Safety Datalink is not a reporting system. It’s an active surveillance of medical records in the Kaiser Permanente system. The VAERS is a passive system, so it requires individuals to report GBS cases to the VAERS team, Dr. Klein explained.

So although the two studies are slightly different, overall, the VAERS data is “consistent with what we found,” she said.

Also weighing in, C. Buddy Creech, MD, MPH, director of the Vanderbilt Vaccine Research Program and professor of pediatrics at the Vanderbilt University School of Medicine, Nashville, Tenn., said it is “important to realize that GBS had been observed after adenovirus-vectored vaccines earlier in the pandemic, both for the AstraZeneca vaccine and the Janssen vaccine.”

The Advisory Committee on Immunization Practices (ACIP) preferentially recommends that people age 18 years and older receive an mRNA COVID-19 vaccine rather than the Janssen adenoviral vector vaccine when both types of COVID-19 vaccine are available.

“Thus, the use of the Janssen vaccine is remarkably low in the U.S. right now,” Dr. Creech said.

“Nevertheless, we have a firm commitment, both scientifically and ethically, to track potential side effects after vaccination and to make sure that the vaccines in use for COVID, and other important infectious diseases, are safe and effective,” he added.

The study had no commercial funding. Dr. Abara and Dr. Creech have reported no relevant financial relationships. Dr. Klein reported having received grants from Pfizer research support for a COVID vaccine clinical trial, as well as grants from Merck, GlaxoSmithKline, Sanofi Pasteur, and Protein Science (now Sanofi Pasteur).

Unlike VAERS, the Vaccine Safety Datalink is not a reporting system. It’s an active surveillance of medical records in the Kaiser Permanente system. The VAERS is a passive system, so it requires individuals to report GBS cases to the VAERS team, Dr. Klein explained.

So although the two studies are slightly different, overall, the VAERS data is “consistent with what we found,” she said.

Also weighing in, C. Buddy Creech, MD, MPH, director of the Vanderbilt Vaccine Research Program and professor of pediatrics at the Vanderbilt University School of Medicine, Nashville, Tenn., said it is “important to realize that GBS had been observed after adenovirus-vectored vaccines earlier in the pandemic, both for the AstraZeneca vaccine and the Janssen vaccine.”

The Advisory Committee on Immunization Practices (ACIP) preferentially recommends that people age 18 years and older receive an mRNA COVID-19 vaccine rather than the Janssen adenoviral vector vaccine when both types of COVID-19 vaccine are available.

“Thus, the use of the Janssen vaccine is remarkably low in the U.S. right now,” Dr. Creech said.

“Nevertheless, we have a firm commitment, both scientifically and ethically, to track potential side effects after vaccination and to make sure that the vaccines in use for COVID, and other important infectious diseases, are safe and effective,” he added.

The study had no commercial funding. Dr. Abara and Dr. Creech have reported no relevant financial relationships. Dr. Klein reported having received grants from Pfizer research support for a COVID vaccine clinical trial, as well as grants from Merck, GlaxoSmithKline, Sanofi Pasteur, and Protein Science (now Sanofi Pasteur).

Nonstop inflammation and immune problems top the list of potential causes of long COVID, but doctors say it’s growing clear that more than one thing is to blame for the wide swath of often debilitating symptoms that could last months or even years.

“I think that it’s a much more complex picture than just inflammation, or just autoimmunity, or just immune dysregulation. And it’s probably a combination of all three causing a cascade of effects that then manifests itself as brain fog, or shortness of breath, or chronic fatigue,” says Alexander Truong, MD, a pulmonologist and assistant professor at Emory University, Atlanta, who also runs a long-COVID clinic.

Long COVID, post–COVID-19 condition, and postacute sequelae of SARS-CoV-2 (PASC) are among the terms used by the National Institutes of Health to describe the long-term health issues faced by an estimated 10%-30% of people infected with COVID-19. Symptoms – as many as 200 – can range from inconvenient to crippling, damage multiple organ systems, come and go, and relapse. Long COVID increases the risk of worsening existing health problems and triggering new ones, including cardiovascular disease and type 2 diabetes.

So far, research suggests there is no single cause, condition, or disease that explains why some people have an extensive range of symptoms long after the early COVID-19 infection has cleared up. Many experts believe some combination of biological processes – including the virus hanging around in our bodies, inflammation, autoimmunity, tiny blood clots, immune system problems, and even the reactivation of dormant viruses such as the Epstein-Barr virus – could be the culprit, a theory also supported by a comprehensive and in-depth review of long-COVID studies published in the journal Nature Reviews Microbiology.

“It’s become clear over the last couple of years that there are different [symptoms] of long COVID … that cannot all be lumped together,” says Michael Peluso, MD, an assistant professor of medicine and an infectious diseases doctor at the University of California, San Francisco.
 

Inflammation and a virus that hangs around

Multiple studies have shown that the virus or pieces of it can remain in many parts of the body, including the kidneys, brain, heart, and gastrointestinal system, long after the early infection. 

“One major question that I think is the area of most intense investigation now is whether there is viral persistence that is driving immune dysregulation and therefore symptoms,” says Dr. Peluso.

A small Harvard University study, for example, found evidence that reservoirs of the coronavirus could linger in patients up to a year after they’re first diagnosed. 

An earlier German study found that patients with post-COVID-19 symptoms had higher levels of three cytokines – small proteins that tell the body’s immune system what to do and are involved in the growth and activity of immune system cells and blood cells. Researchers said the results supported the theory that there is persistent reprogramming of certain immune cells, and that the uncontrolled “self-fueled hyperinflammation” during the early COVID-19 infection can become continued immune cell disruption that drives long-COVID symptoms.

“Long COVID is more likely due to either an inflammatory response by the body or reservoirs of virus that the body is still trying to clear … and the symptoms we’re seeing are a side effect of that,” says Rainu Kaushal, MD, senior associate dean for clinical research at Weill Cornell Medicine in New York.

Australian researchers found that immune system recovery appeared different, compared with those who were infected with other common coronaviruses.

These findings also support concerns that some experts express over the long-term risks of COVID-19 infections in general, but especially repeat infections.

“Anything that kind of revs up inflammation in the body can boil that pot over and make the symptoms worse. That’s very easily an infection or some other insult to the body. So that’s the generalized hypothesis as to why insults to the body may worsen the symptoms,” says Dr. Truong.
 

An autoimmune condition?

But inflammation alone does not fully explain post–COVID-19 problems.

Dr. Truong and his team, for example, have been documenting inflammatory markers in patients at the post-COVID clinic he cofounded more than 2 years ago at Emory Executive Park in Atlanta. When the clinic was first launched, high-dose nonsteroidal anti-inflammatory drugs – including ibuprofen – and prednisone were prescribed to long-COVID patients.

“It didn’t make a difference at all for any of these folks,” he says, adding that there are signs that autoimmunity is at play. But he cautions that it is still too early to suggest treating long-COVID patients with medications used for other autoimmune conditions.

In autoimmune conditions such as rheumatoid arthritis, lupus, and type 1 diabetes, a person’s immune system can’t tell normal cells from foreign pathogens and attacks healthy cells. There is typically no single diagnostic test, and many share similar symptoms, making detection and diagnosis potentially difficult, according to Johns Hopkins Medicine.

A small study published in the journal  Science Translational Medicine found that, among patients who failed to regain their sense of smell long after their initial infection, there was inflammation in the nose tissue where smell nerve cells are found, even though no detectable virus remained. Fewer olfactory sensory neurons were seen, as well – findings that researchers said resembled some kind of “autoimmune-like process.”

Meanwhile, scientists in Canada found signs of autoimmunity in blood samples taken from patients who still had fatigue and shortness of breath after their initial COVID-19 infection. Two specific proteins were present a year after infection in up to 30% of patients, many of whom still had shortness of breath and fatigue, the researchers reported in the Jan. 1 issue of the European Respiratory Journal. These patients had been healthy and had no autoimmune condition or other diseases before they were infected.
 

Immune system problems

A number of studies have suggested that a problematic immune response could also explain why symptoms persist for some people.

Researchers in France, for example, found that the immune response problems in those with severe COVID-19 infections caused exaggerated or uncontrolled formation of a type of bug-fighting defense mechanism called a neutrophil extracellular trap (NET), which in turn triggers harmful inflammation that can result in multiorgan damage. These traps are netlike structures made from fibers composed mostly of DNA strings that bind, or trap, pathogens.

Long COVID is not like an acute infectious disease, says Alexander Charney, MD, PhD, the lead principal investigator of the RECOVER adult cohort at Mount Sinai in New York, and an associate professor at Icahn School of Medicine at Mount Sinai. It is more similar to other complex chronic diseases that have taken decades to understand, such as heart disease, mental illness, and rheumatologic diseases, he says.
 

Biomarkers and blood clots

Scientists are homing in on biomarkers, or detectable and measurable traits – in this case, molecular indicators – that can make diagnosing long COVID easier and give better direction for treatment. These biomarkers are also key to helping sort out the complex biology of long COVID.

In one study, data from blood samples taken from hundreds of hospitalized COVID-19 patients suggests changes are happening at the molecular level during initial severe infections. These changes may be tied to the development of longer-term symptoms, according to the study by Dr. Charney and his team at Mount Sinai published in Nature Medicine

Blood clotting issues have also been detected in long COVID patients. At least one study found signs that long-COVID patients had higher levels of a type of auto-antibody linked to the abnormal formation of clots. Researchers suspect that tiny, persistent microclots – undetectable via regular pathology tests – may be cutting off oxygen flow to tissue by blocking capillaries – and could explain many of the post-COVID symptoms described by patients.

While enormous progress has been made toward understanding long COVID, the research is still considered early and faces many challenges, including varying criteria used to define the condition, the types and quality of data used, differences in how patients are defined and recruited, and the small size of many studies. Some research also appears to conflict with other studies. And while there are specialized tools for diagnosing some aspects of the condition, standard tests often don’t detect many of the signs seen in long-COVID patients. But given the urgency and global scale of the problem, experts say more funding and support should be prioritized.

“People are suffering now, and they want answers now. ... It’s not like with COVID, where the path towards a great and meaningful solution to this unbelievable problem was clear – we need a vaccine,” says Dr. Charney. 

“It’s going to be a long haul to figure out what is going on.”
