The emerging COVID-19 variant BQ.1 and one of its descendants now account for more than 1 in 10 cases in the United States, according to the CDC’s latest data.

Just 1 month ago, the variant accounted for less than 1% of cases.

“When you get variants like that, you look at what their rate of increase is as a relative proportion of the variants, and this has a pretty troublesome doubling time,” Anthony Fauci, MD, said in an interview with CBS News. Dr. Fauci is the director of the National Institute of Allergy and Infectious Diseases and also the chief medical adviser to President Joe Biden.

There are also concerning features of the BQ.1 variant, which include mutations that could potentially escape vaccines and treatments for COVID-19. 

Currently, the most widespread variant in the U.S. is the Omicron subvariant known as BA.5, which accounts for 68% of all infections. One of the go-to treatments for BA.5 infections is monoclonal antibodies, which may not be as effective when fighting the up-and-coming strains of BQ.1 and its descendant BQ.1.1, according to experts.  

“That’s the reason why people are concerned about BQ.1.1, for the double reason of its doubling time and the fact that it seems to elude important monoclonal antibodies,” Dr. Fauci told CBS News. 

Currently, BQ.1 and BQ.1.1 appear most widespread in the New York and New Jersey region, accounting for nearly 20% of infections there, according to the CDC. 

But because the new variant is a descendant of Omicron, Dr. Fauci said the currently available booster shots are still the best first line of protection against this up-and-coming threat.

“The bad news is that there’s a new variant that’s emerging and that has qualities or characteristics that could evade some of the interventions we have. But, the somewhat encouraging news is that it’s a BA.5 sub-lineage, so there is almost certainly going to be some cross-protection that you can boost up,” he said.

In the decade since the Sandy Hook Elementary School shootings, the United States has experienced more than 3,300 mass shootings, according to the Gun Violence Archive.

The latest NPR/PBS NewsHour/Marist poll shows that that the margin of public opinion in the United States is the widest that it has been during the past 10 years in favor of taking steps to control gun violence; 59% of U.S. adults said it’s more important to control gun violence than to protect gun rights, and 35% said the opposite.

Have physicians’ opinions about gun issues in our country shifted meaningfully during that period? That’s a complex question that can be informed with the basic snapshot provided by doctors› comments to New York University (and Medscape blogger) bioethicist Arthur L. Caplan’s four video blogs on whether physicians should discuss gun safety with their patients. Dr. Caplan’s video blogs appeared on the Medscape website in 2014, 2016, 2018, and 2022.

Hundreds of physicians have posted comments to Dr. Caplan’s arguments that doctors should bring up gun safety when talking to their patients. The great majority of comments opposed his position in 2014, and that remained the case through 2022, regardless of incidents of gun-related violence. Supportive comments have been a small minority that has grown only slightly over his four video blogs.
 

Physicians’ lack of qualifications

The most prevalent counterarguments expressed against Dr. Caplan’s position are that physicians lack the proper knowledge to discuss gun safety with patients; and the responsibility falls on family members, certified firearms instructors, teachers, and others – but not doctors – to educate people about firearm safety.

“Then there’s a third group that says, ‘I don’t want to do this because I am too busy trying to figure out what is wrong with the patient,’ ” Dr. Caplan says.

Here are a few on-point comments that were posted to his video blogs:

• “Unless physicians become certified firearms instructors like myself, they are not qualified to talk to patients on the subject and should advise patients to find a program and take a course.” – Dr. Ken Long, March 31, 2014
• “Gun safety should be taught in school, just like health and sex education.” – Patricia L., Feb. 11, 2016
• “None of my medical or surgical training or experience qualifies me as a policy expert on gun laws or regulations.” – Dr. Kelly Hyde, Dec. 23, 2018
• “I have the Constitution hanging in my office with an NRA plaque next to it. Most MDs can’t mow their own yard.” – Dr. Brian Anseeuw, June 21, 2022

Do mental health issues trump gun talks?

Another counterargument to discussing gun safety with patients involves mental health issues that many physicians may not be trained to address. Mental health entered comments to Dr. Caplan’s video blogs in 2016 and has shaped much of the discussion since.

• “First of all, two-thirds of gun deaths are suicides. It is foolish to talk about counseling patients about gun safety, etc, and ignore the mental health issues.” – Dr. Jeffrey Jennings, Jan. 25, 2016
• “Suicide victims and those committing mass shootings are mentally ill. ... Blame society, drugs, mental illness, easy access to illegal firearms, and poor recognition of SOS (signs of suicide).” – Dr. Alan DeCarlo, Dec. 24, 2018
• “Yes, we have gun violence, but what is the underlying problem? Bullying? Mental issues? Not enough parental supervision? These and others are the issues I feel need to be discussed.” – T. Deese, June 24, 2022
• “The causes of increased gun violence are mental health, problems with bullying, social media, and normalization of deviant behavior.” – Julie Johng, 2022

Added responsibility is too much

Another theme that has grown over time is that talks of gun safety just heap issues onto physicians’ treatment plates that are already too full.

• “Oh, for God’s sake, is there anything else I can do while I›m at it? Primary care has gotten to be more headache than it’s worth. Thanks for another reason to think about retiring.” – Dr. Kathleen Collins, March 31, 2014
• “THE JOB OF POLICE, COURTS, AND LAW-EDUCATED PROSECUTORS SHOULD NOT BE HANDLED BY PHYSICIANS.” – Dr. Sudarshan Singla, Jan. 25, 2016
• “This is a debate that only those at the academic/ivory tower–level of medicine even have time to lament. The frontline medical providers barely have enough time to adequately address the pertinent.” – Tobin Purslow, Jan. 15, 2016

Other ways to communicate

For his part, Dr. Caplan believes there is a variety of ways physicians can effectively discuss gun safety with patients to help minimize the potential of injury or death.

Acknowledging that other aspects of treatment are often more pressing, he suggested that the gun safety education could be done through educational videos that are shown in waiting rooms, through pamphlets available at the front desk, or throuigh a newsletter sent to patients.

“Everything doesn’t have to happen in conversation. The doctor’s office should become more of an educational site.

“I am 100% more passionate about this than when I first started down this road.”

Gregory A. Hood, MD, remembers a patient of his who was perpetually dubious about COVID-19 – and then couldn’t be saved.

“I spoke to him on many occasions about the dangers of COVID, but he just didn’t believe me,” said Dr. Hood, an internist in Lexington, Ky. “He just didn’t give me enough time to help him. He waited to let me know he was ill with COVID and took days to pick up the medicine. Unfortunately, he then passed away.”
 

The rise of the skeptical patient

It can be extremely frustrating for doctors when patients question or disbelieve their physician’s medical advice and explanations. And many physicians resent the amount of time they spend trying to explain or make their case, especially during a busy day. But patients’ skepticism about the validity of some treatments seems to be increasing.

“Patients are now more likely to have their own medical explanation for their complaint than they used to, and that can be bad for their health,” Dr. Hood said.

Dr. Hood sees medical cynicism as part of Americans’ growing distrust of experts, leveraged by easy access to the internet. “When people Google, they tend to look for support of their opinions, rather than arrive at a fully educated decision.”

Only about half of patients believe their physicians “provide fair and accurate treatment information all or most of the time,” according to a 2019 survey by the Pew Research Center.

Patients’ distrust has become more obvious during the COVID-19 pandemic, said John Schumann, MD, an internist with Oak Street Health, a practice with more than 500 physicians and other providers in 20 states, treating almost exclusively Medicare patients.

“The skeptics became more entrenched during the pandemic,” said Dr. Schumann, who is based in Tulsa, Okla. “They may think the COVID vaccines were approved too quickly, or believe the pandemic itself is a hoax.”

“There’s a lot of antiscience rhetoric now,” Dr. Schumann added. “I’d say about half of my patients are comfortable with science-based decisions and the other half are not.”
 

What are patients mistrustful about?

Patients’ suspicions of certain therapies began long before the pandemic. In dermatology, for example, some patients refuse to take topical steroids, said Steven R. Feldman, MD, a dermatologist in Winston-Salem, N.C.

“Their distrust is usually based on anecdotal stories they read about,” he noted. “Patients in other specialties are dead set against vaccinations.”

In addition to refusing treatments and inoculations, some patients ask for questionable regimens mentioned in the news. “Some patients have demanded hydroxychloroquine or Noromectin, drugs that are unproven in the treatment of COVID,” Dr. Schumann said. “We refuse to prescribe them.”

Dr. Hood said patients’ reluctance to follow medical advice can often be based on cost. “I have a patient who was more willing to save $20 than to save his life. But when the progression of his test results fit my predictions, he became more willing to take treatments. I had to wait for the opportune moment to convince him.”

Many naysayer patients keep their views to themselves, and physicians may be unaware that the patients are stonewalling. A 2006 study estimated that about 10%-16% of primary care patients actively resist medical authority.

Dr. Schumann cited patients who don’t want to hear an upsetting diagnosis. “Some patients might refuse to take a biopsy to see if they have cancer because they don’t want to know,” he said. “In many cases, they simply won’t get the biopsy and won’t tell the doctor that they didn’t.”
 

Sometimes skeptics’ arguments have merit

Some patients’ concerns can be valid, such as when they refuse to go on statins, said Zain Hakeem, DO, a physician in Austin, Tex.

“In some cases, I feel that statins are not necessary,” he said. “The science on statins for primary prevention is not strong, although they should be used for exceedingly high-risk patients.”

Certain patients, especially those with chronic conditions, do a great deal of research, using legitimate sources on the Web, and their research is well supported.

However, these patients can be overconfident in their conclusions. Several studies have shown that with just a little experience, people can replace beginners’ caution with a false sense of competence.

For example, “Patients may not weigh the risks correctly,” Dr. Hakeem said. “They can be more concerned about the risk of having their colon perforated during a colonoscopy, while the risk of cancer if they don’t have a colonoscopy is much higher.”

Some highly successful people may be more likely to trust their own medical instincts. When Steve Jobs, the founder of Apple, was diagnosed with pancreatic cancer in 2003, he put off surgery for 9 months while he tried to cure his disease with a vegan diet, acupuncture, herbs, bowel cleansings, and other remedies he read about. He died in 2011. Some experts believe that delay hastened his death.

Of course, not all physicians’ diagnoses or treatments are correct. One study indicated doctors’ diagnostic error rate could be as high as 15%. And just as patients can be overconfident in their conclusions, so can doctors. Another study found that physicians’ stated confidence in their diagnosis was only slightly affected by the inaccuracy of that diagnosis or the difficulty of the case.
 

Best ways to deal with cynical patients

Patients’ skepticism can frustrate doctors, reduce the efficiency of care delivery, and interfere with recovery. What can doctors do to deal with these problems?

1. Build the patient’s trust in you. “Getting patients to adhere to your advice involves making sure they feel they have a caring doctor whom they trust,” Dr. Feldman said.

“I want to show patients that I am entirely focused on them,” he added. “For example, I may rush to the door of the exam room from my last appointment, but I open the door very slowly and deliberately, because I want the patient to see that I won’t hurry with them.”

2. Spend time with the patient. Familiarity builds trust. Dr. Schumann said doctors at Oak Street Health see their patients an average of six to eight times a year, an unusually high number. “The more patients see their physicians, the more likely they are to trust them.”

3. Keep up to date. “I make sure I’m up to date with the literature, and I try to present a truthful message,” Dr. Hood said. “For instance, my research showed that inflammation played a strong role in developing complications from COVID, so I wrote a detailed treatment protocol aimed at the inflammation and the immune response, which has been very effective.”

4. Confront patients tactfully. Patients who do research on the Web don’t want to be scolded, Dr. Feldman said. In fact, he praises them, even if he doesn’t agree with their findings. “I might say: ‘What a relief to finally find patients who’ve taken the time to educate themselves before coming here.’ ”

Dr. Feldman is careful not to dispute patients’ conclusions. “Debating the issues is not an effective approach to get patients to trust you. The last thing you want to tell a patient is: ‘Listen to me! I’m an expert.’ People just dig in.”

However, it does help to give patients feedback. “I’m a big fan of patients arguing with me,” Dr. Hakeem said. “It means you can straighten out misunderstandings and improve decision-making.”

5. Explain your reasoning. “You need to communicate clearly and show them your thinking,” Dr. Hood said. “For instance, I’ll explain why a patient has a strong risk for heart attack.”

6. Acknowledge uncertainties. “The doctor may present the science as far more certain than it is,” Dr. Hakeem said. “If you don’t acknowledge the uncertainties, you could break the patient’s trust in you.”

7. Don’t use a lot of numbers. “Data is not a good tool to convince patients,” Dr. Feldman said. “The human brain isn’t designed to work that way.”

If you want to use numbers to show clinical risk, Dr. Hakeem advisd using natural frequencies, such as 10 out of 10,000, which is less confusing to the patient than the equivalent percentage of 0.1%.

It can be helpful to refer to familiar concepts. One way to understand a risk is to compare it with risks in daily life, such as the dangers of driving or falling in the shower, Dr. Hakeem added.

Dr. Feldman often refers to another person’s experience when presenting his medical advice. “I might say to the patient: ‘You remind me of another patient I had. They were sitting in the same chair you’re sitting in. They did really well on this drug, and I think it’s probably the best choice for you, too.’ ”

8. Adopt shared decision-making. This approach involves empowering the patient to become an equal partner in medical decisions. The patient is given information through portals and is encouraged to do research. Critics, however, say that most patients don’t want this degree of empowerment and would rather depend on the doctor’s advice.

Conclusion

It’s often impossible to get through to a skeptical patient, which can be disheartening for doctors. “Physicians want to do what is best for the patient, so when the patient doesn’t listen, they may take it personally,” Dr. Hood said. “But you always have to remember, the patient is the one with disease, and it’s up to the patient to open the door.”

Still, some skeptical patients ultimately change their minds. Dr. Schumann said patients who initially declined the COVID vaccine eventually decided to get it. “It often took them more than a year. but it’s never too late.”

Dr. Hood said patients’ reluctance to follow medical advice can often be based on cost. “I have a patient who was more willing to save $20 than to save his life. But when the progression of his test results fit my predictions, he became more willing to take treatments. I had to wait for the opportune moment to convince him.”

Many naysayer patients keep their views to themselves, and physicians may be unaware that the patients are stonewalling. A 2006 study estimated that about 10%-16% of primary care patients actively resist medical authority.

Dr. Schumann cited patients who don’t want to hear an upsetting diagnosis. “Some patients might refuse to take a biopsy to see if they have cancer because they don’t want to know,” he said. “In many cases, they simply won’t get the biopsy and won’t tell the doctor that they didn’t.”
 

Sometimes skeptics’ arguments have merit

Some patients’ concerns can be valid, such as when they refuse to go on statins, said Zain Hakeem, DO, a physician in Austin, Tex.

“In some cases, I feel that statins are not necessary,” he said. “The science on statins for primary prevention is not strong, although they should be used for exceedingly high-risk patients.”

Certain patients, especially those with chronic conditions, do a great deal of research, using legitimate sources on the Web, and their research is well supported.

However, these patients can be overconfident in their conclusions. Several studies have shown that with just a little experience, people can replace beginners’ caution with a false sense of competence.

For example, “Patients may not weigh the risks correctly,” Dr. Hakeem said. “They can be more concerned about the risk of having their colon perforated during a colonoscopy, while the risk of cancer if they don’t have a colonoscopy is much higher.”

Some highly successful people may be more likely to trust their own medical instincts. When Steve Jobs, the founder of Apple, was diagnosed with pancreatic cancer in 2003, he put off surgery for 9 months while he tried to cure his disease with a vegan diet, acupuncture, herbs, bowel cleansings, and other remedies he read about. He died in 2011. Some experts believe that delay hastened his death.

Of course, not all physicians’ diagnoses or treatments are correct. One study indicated doctors’ diagnostic error rate could be as high as 15%. And just as patients can be overconfident in their conclusions, so can doctors. Another study found that physicians’ stated confidence in their diagnosis was only slightly affected by the inaccuracy of that diagnosis or the difficulty of the case.
 

Best ways to deal with cynical patients

Patients’ skepticism can frustrate doctors, reduce the efficiency of care delivery, and interfere with recovery. What can doctors do to deal with these problems?

1. Build the patient’s trust in you. “Getting patients to adhere to your advice involves making sure they feel they have a caring doctor whom they trust,” Dr. Feldman said.

“I want to show patients that I am entirely focused on them,” he added. “For example, I may rush to the door of the exam room from my last appointment, but I open the door very slowly and deliberately, because I want the patient to see that I won’t hurry with them.”

2. Spend time with the patient. Familiarity builds trust. Dr. Schumann said doctors at Oak Street Health see their patients an average of six to eight times a year, an unusually high number. “The more patients see their physicians, the more likely they are to trust them.”

3. Keep up to date. “I make sure I’m up to date with the literature, and I try to present a truthful message,” Dr. Hood said. “For instance, my research showed that inflammation played a strong role in developing complications from COVID, so I wrote a detailed treatment protocol aimed at the inflammation and the immune response, which has been very effective.”

4. Confront patients tactfully. Patients who do research on the Web don’t want to be scolded, Dr. Feldman said. In fact, he praises them, even if he doesn’t agree with their findings. “I might say: ‘What a relief to finally find patients who’ve taken the time to educate themselves before coming here.’ ”

Dr. Feldman is careful not to dispute patients’ conclusions. “Debating the issues is not an effective approach to get patients to trust you. The last thing you want to tell a patient is: ‘Listen to me! I’m an expert.’ People just dig in.”

However, it does help to give patients feedback. “I’m a big fan of patients arguing with me,” Dr. Hakeem said. “It means you can straighten out misunderstandings and improve decision-making.”

5. Explain your reasoning. “You need to communicate clearly and show them your thinking,” Dr. Hood said. “For instance, I’ll explain why a patient has a strong risk for heart attack.”

6. Acknowledge uncertainties. “The doctor may present the science as far more certain than it is,” Dr. Hakeem said. “If you don’t acknowledge the uncertainties, you could break the patient’s trust in you.”

7. Don’t use a lot of numbers. “Data is not a good tool to convince patients,” Dr. Feldman said. “The human brain isn’t designed to work that way.”

If you want to use numbers to show clinical risk, Dr. Hakeem advisd using natural frequencies, such as 10 out of 10,000, which is less confusing to the patient than the equivalent percentage of 0.1%.

It can be helpful to refer to familiar concepts. One way to understand a risk is to compare it with risks in daily life, such as the dangers of driving or falling in the shower, Dr. Hakeem added.

Dr. Feldman often refers to another person’s experience when presenting his medical advice. “I might say to the patient: ‘You remind me of another patient I had. They were sitting in the same chair you’re sitting in. They did really well on this drug, and I think it’s probably the best choice for you, too.’ ”

8. Adopt shared decision-making. This approach involves empowering the patient to become an equal partner in medical decisions. The patient is given information through portals and is encouraged to do research. Critics, however, say that most patients don’t want this degree of empowerment and would rather depend on the doctor’s advice.

Conclusion

It’s often impossible to get through to a skeptical patient, which can be disheartening for doctors. “Physicians want to do what is best for the patient, so when the patient doesn’t listen, they may take it personally,” Dr. Hood said. “But you always have to remember, the patient is the one with disease, and it’s up to the patient to open the door.”

Still, some skeptical patients ultimately change their minds. Dr. Schumann said patients who initially declined the COVID vaccine eventually decided to get it. “It often took them more than a year. but it’s never too late.”

A version of this article first appeared on Medscape.com.

Gregory A. Hood, MD, remembers a patient of his who was perpetually dubious about COVID-19 – and then couldn’t be saved.

“I spoke to him on many occasions about the dangers of COVID, but he just didn’t believe me,” said Dr. Hood, an internist in Lexington, Ky. “He just didn’t give me enough time to help him. He waited to let me know he was ill with COVID and took days to pick up the medicine. Unfortunately, he then passed away.”
 

The rise of the skeptical patient

It can be extremely frustrating for doctors when patients question or disbelieve their physician’s medical advice and explanations. And many physicians resent the amount of time they spend trying to explain or make their case, especially during a busy day. But patients’ skepticism about the validity of some treatments seems to be increasing.

“Patients are now more likely to have their own medical explanation for their complaint than they used to, and that can be bad for their health,” Dr. Hood said.

Dr. Hood sees medical cynicism as part of Americans’ growing distrust of experts, leveraged by easy access to the internet. “When people Google, they tend to look for support of their opinions, rather than arrive at a fully educated decision.”

Only about half of patients believe their physicians “provide fair and accurate treatment information all or most of the time,” according to a 2019 survey by the Pew Research Center.

Patients’ distrust has become more obvious during the COVID-19 pandemic, said John Schumann, MD, an internist with Oak Street Health, a practice with more than 500 physicians and other providers in 20 states, treating almost exclusively Medicare patients.

“The skeptics became more entrenched during the pandemic,” said Dr. Schumann, who is based in Tulsa, Okla. “They may think the COVID vaccines were approved too quickly, or believe the pandemic itself is a hoax.”

“There’s a lot of antiscience rhetoric now,” Dr. Schumann added. “I’d say about half of my patients are comfortable with science-based decisions and the other half are not.”
 

What are patients mistrustful about?

Patients’ suspicions of certain therapies began long before the pandemic. In dermatology, for example, some patients refuse to take topical steroids, said Steven R. Feldman, MD, a dermatologist in Winston-Salem, N.C.

“Their distrust is usually based on anecdotal stories they read about,” he noted. “Patients in other specialties are dead set against vaccinations.”

In addition to refusing treatments and inoculations, some patients ask for questionable regimens mentioned in the news. “Some patients have demanded hydroxychloroquine or Noromectin, drugs that are unproven in the treatment of COVID,” Dr. Schumann said. “We refuse to prescribe them.”

Dr. Hood said patients’ reluctance to follow medical advice can often be based on cost. “I have a patient who was more willing to save $20 than to save his life.

Workers in the hard rock and other mining industries were significantly more likely to develop rheumatoid arthritis than were controls in the general population, based on data from nearly 2,000 individuals.

Although respirable silica exposure has been consistently linked to rheumatoid arthritis (RA) in a variety of occupations including foundry work, construction, and stone crushing and drilling, the association between RA risk and hard rock mining has not been investigated, lead author Paul D. Blanc, MD, of the University of California, San Francisco, and colleagues wrote in a study published in JAMA Network Open.

“Many clinical rheumatologists and most generalists are unaware that what a person does for a living can be a risk factor for rheumatoid arthritis,” Dr. Blanc said in an interview. “This study makes an important contribution to showing that work exposures can more than double the risk of RA,” he said.

“We were surprised by the widespread nature of the work-related risk within and beyond the mining sector,” Dr. Blanc noted. Given the range of potential occupational exposures, his take-home message to rheumatologists is to ask each and every patient about their work history.

The researchers conducted random telephone surveys of 1,988 men aged 50 years and older living in the Four Corners region of the United States (Colorado, New Mexico, and Utah) in counties selected for high levels of pneumoconiosis mortality. The surveys were conducted between Jan. 12, 2021, and May 4, 2021. The mean age of the study population was 68.6 years, and 82.6% were non-Hispanic White. Approximately half reported being former or current smokers.

RA was defined as having a clinician diagnosis, and was further defined by treatment with corticosteroids or disease-modifying antirheumatic drugs (DMARDs).

A total of 262 respondents (13.1%) reported work in surface mining or ore processing, with no underground exposure; 118 respondents (5.9%) reported work in underground hard rock mining; and 62 (3.1%) reported work in underground mining of other type, primarily coal mining.

Overall, after adjusting for age, smoking, and nonmining silica exposure, any mining work was associated with a three- to fourfold increased risk of RA for individuals with a RA diagnosis who were treated with corticosteroids and those treated with DMARDs (odds ratios, 4.12 and 3.30, respectively).

The risk was approximately nine times and six times higher for individuals with a history of underground soft rock mining (mainly coal, no hard rock mining), with odds ratios of 9.74 and 6.42, for those with RA treated with corticosteroids and DMARDs, respectively.

The odds of RA were higher with coal and other underground fossil hydrocarbon mining, compared with underground hard rock mining, the researchers wrote in their discussion. Reasons for this difference could include the longer employment duration for underground coal mining, but also the possibility that “in coal mining, silica inhalation may not be the sole cause, but rather that carbonaceous materials may also be involved etiologically in RA risk in that occupation,” they wrote. No association was found between increased risk of RA and current or former smoking, they noted, in contrast to the researchers’ previous studies of Appalachian coal miners.

The study findings were limited by several factors including the potential for recall bias and misclassified exposure and diagnoses, the researchers noted. Other limitations include the focus on individuals aged 50 years and older in a limited geographic region of the United States and the relatively short time of employment in mining, they said.

However, the results support previous studies showing an increased RA risk with respirable silica exposure, and suggest that clinicians consider mining among other work exposures that could increase the risk for developing RA, the researchers concluded.

Looking ahead, Dr. Blanc said that additional research is needed to tease out disease progression and severity in the face of past occupational exposures.

The study was supported by the Alpha Foundation and the Russell/Engleman Rheumatology Research Center through grants to the researchers. The researchers had no other financial conflicts to disclose.

Nirmatrelvir/ritonavir (Paxlovid) has been a game changer for high-risk patients with early COVID-19 symptoms but has significant interactions with commonly used cardiovascular medications, a new paper cautions.

COVID-19 patients with cardiovascular disease (CVD) or risk factors such as diabetes, hypertension, and chronic kidney disease are at high risk of severe disease and account for the lion’s share of those receiving Paxlovid. Data from the initial EPIC-HR trial and recent real-world data also suggest they’re among the most likely to benefit from the oral antiviral, regardless of their COVID-19 vaccination status.

“But at the same time, it unfortunately interacts with many very commonly prescribed cardiovascular medications and with many of them in a very clinically meaningful way, which may lead to serious adverse consequences,” senior author Sarju Ganatra, MD, said in an interview. “So, while it’s being prescribed with a good intention to help these people, we may actually end up doing more harm than good.

“We don’t want to deter people from getting their necessary COVID-19 treatment, which is excellent for the most part these days as an outpatient,” he added. “So, we felt the need to make a comprehensive list of cardiac medications and level of interactions with Paxlovid and also to help the clinicians and prescribers at the point of care to make the clinical decision of what modifications they may need to do.”

The paper, published online in the Journal of the American College of Cardiology, details drug-drug interactions with some 80 CV medications including statins, antihypertensive agents, heart failure therapies, and antiplatelet/anticoagulants.

It also includes a color-coded figure denoting whether a drug is safe to coadminister with Paxlovid, may potentially interact and require a dose adjustment or temporary discontinuation, or is contraindicated.

Among the commonly used blood thinners, for example, the paper notes that Paxlovid significantly increases drug levels of the direct oral anticoagulants (DOACs) apixaban, rivaroxaban, edoxaban, and dabigatran and, thus, increases the risk of bleeding.

“It can still be administered, if it’s necessary, but the dose of the DOAC either needs to be reduced or held depending on what they are getting it for, whether they’re getting it for pulmonary embolism or atrial fibrillation, and we adjust for all those things in the table in the paper,” said Dr. Ganatra, from Lahey Hospital and Medical Center, Burlington, Mass.

When the DOAC can’t be interrupted or dose adjusted, however, Paxlovid should not be given, the experts said. The antiviral is safe to use with enoxaparin, a low-molecular-weight heparin, but can increase or decrease levels of warfarin and should be used with close international normalized ratio monitoring.

For patients on antiplatelet agents, clinicians are advised to avoid prescribing nirmatrelvir/ritonavir to those on ticagrelor or clopidogrel unless the agents can be replaced by prasugrel.

Ritonavir – an inhibitor of cytochrome P 450 enzymes, particularly CYP3A4 – poses an increased risk of bleeding when given with ticagrelor, a CYP3A4 substrate, and decreases the active metabolite of clopidogrel, cutting its platelet inhibition by 20%. Although there’s a twofold decrease in the maximum concentration of prasugrel in patients on ritonavir, this does not affect its antiplatelet activity, the paper explains.

Among the lipid-lowering agents, experts suggested temporarily withholding atorvastatin, rosuvastatin, simvastatin, and lovastatin because of an increased risk for myopathy and liver toxicity but say that other statins, fibrates, ezetimibe, and the proprotein convertase subtilisin/kexin type 9 inhibitors evolocumab and alirocumab are safe to coadminister with Paxlovid.

While statins typically leave the body within hours, most of the antiarrhythmic drugs, except for sotalol, are not safe to give with Paxlovid, Dr. Ganatra said. It’s technically not feasible to hold these drugs because most have long half-lives, reaching about 100 days, for example, for amiodarone.

“It’s going to hang around in your system for a long time, so you don’t want to be falsely reassured that you’re holding the drug and it’s going to be fine to go back slowly,” he said. “You need to look for alternative therapies in those scenarios for COVID-19 treatment, which could be other antivirals, or a monoclonal antibody individualized to the patient’s risk.”

Although there’s limited clinical information regarding interaction-related adverse events with Paxlovid, the team used pharmacokinetics and pharmacodynamics data to provide the guidance. Serious adverse events are also well documented for ritonavir, which has been prescribed for years to treat HIV, Dr. Ganatra noted.

The Infectious Disease Society of America also published guidance on the management of potential drug interactions with Paxlovid in May and, earlier in October, the Food and Drug Administration updated its Paxlovid patient eligibility screening checklist.

Still, most prescribers are actually primary care physicians and even pharmacists, who may not be completely attuned, said Dr. Ganatra, who noted that some centers have started programs to help connect primary care physicians with their cardiology colleagues to check on CV drugs in their COVID-19 patients.

“We need to be thinking more broadly and at a system level where the hospital or health care system leverages the electronic health record systems,” he said. “Most of them are sophisticated enough to incorporate simple drug-drug interaction information, so if you try to prescribe someone Paxlovid and it’s a heart transplant patient who is on immunosuppressive therapy or a patient on a blood thinner, then it should give you a warning ... or at least give them a link to our paper or other valuable resources.

“If someone is on a blood thinner and the blood thinner level goes up by ninefold, we can only imagine what we would be dealing with,” Dr. Ganatra said. “So, these interactions should be taken very seriously and I think it’s worth the time and investment.”

The authors reported no relevant financial relationships.

“But at the same time, it unfortunately interacts with many very commonly prescribed cardiovascular medications and with many of them in a very clinically meaningful way, which may lead to serious adverse consequences,” senior author Sarju Ganatra, MD, said in an interview. “So, while it’s being prescribed with a good intention to help these people, we may actually end up doing more harm than good.

“We don’t want to deter people from getting their necessary COVID-19 treatment, which is excellent for the most part these days as an outpatient,” he added. “So, we felt the need to make a comprehensive list of cardiac medications and level of interactions with Paxlovid and also to help the clinicians and prescribers at the point of care to make the clinical decision of what modifications they may need to do.”

The paper, published online in the Journal of the American College of Cardiology, details drug-drug interactions with some 80 CV medications including statins, antihypertensive agents, heart failure therapies, and antiplatelet/anticoagulants.

It also includes a color-coded figure denoting whether a drug is safe to coadminister with Paxlovid, may potentially interact and require a dose adjustment or temporary discontinuation, or is contraindicated.

Among the commonly used blood thinners, for example, the paper notes that Paxlovid significantly increases drug levels of the direct oral anticoagulants (DOACs) apixaban, rivaroxaban, edoxaban, and dabigatran and, thus, increases the risk of bleeding.

“It can still be administered, if it’s necessary, but the dose of the DOAC either needs to be reduced or held depending on what they are getting it for, whether they’re getting it for pulmonary embolism or atrial fibrillation, and we adjust for all those things in the table in the paper,” said Dr. Ganatra, from Lahey Hospital and Medical Center, Burlington, Mass.

When the DOAC can’t be interrupted or dose adjusted, however, Paxlovid should not be given, the experts said. The antiviral is safe to use with enoxaparin, a low-molecular-weight heparin, but can increase or decrease levels of warfarin and should be used with close international normalized ratio monitoring.

For patients on antiplatelet agents, clinicians are advised to avoid prescribing nirmatrelvir/ritonavir to those on ticagrelor or clopidogrel unless the agents can be replaced by prasugrel.

Ritonavir – an inhibitor of cytochrome P 450 enzymes, particularly CYP3A4 – poses an increased risk of bleeding when given with ticagrelor, a CYP3A4 substrate, and decreases the active metabolite of clopidogrel, cutting its platelet inhibition by 20%. Although there’s a twofold decrease in the maximum concentration of prasugrel in patients on ritonavir, this does not affect its antiplatelet activity, the paper explains.

Among the lipid-lowering agents, experts suggested temporarily withholding atorvastatin, rosuvastatin, simvastatin, and lovastatin because of an increased risk for myopathy and liver toxicity but say that other statins, fibrates, ezetimibe, and the proprotein convertase subtilisin/kexin type 9 inhibitors evolocumab and alirocumab are safe to coadminister with Paxlovid.

While statins typically leave the body within hours, most of the antiarrhythmic drugs, except for sotalol, are not safe to give with Paxlovid, Dr. Ganatra said. It’s technically not feasible to hold these drugs because most have long half-lives, reaching about 100 days, for example, for amiodarone.

“It’s going to hang around in your system for a long time, so you don’t want to be falsely reassured that you’re holding the drug and it’s going to be fine to go back slowly,” he said. “You need to look for alternative therapies in those scenarios for COVID-19 treatment, which could be other antivirals, or a monoclonal antibody individualized to the patient’s risk.”

Although there’s limited clinical information regarding interaction-related adverse events with Paxlovid, the team used pharmacokinetics and pharmacodynamics data to provide the guidance. Serious adverse events are also well documented for ritonavir, which has been prescribed for years to treat HIV, Dr. Ganatra noted.

The Infectious Disease Society of America also published guidance on the management of potential drug interactions with Paxlovid in May and, earlier in October, the Food and Drug Administration updated its Paxlovid patient eligibility screening checklist.

Still, most prescribers are actually primary care physicians and even pharmacists, who may not be completely attuned, said Dr. Ganatra, who noted that some centers have started programs to help connect primary care physicians with their cardiology colleagues to check on CV drugs in their COVID-19 patients.

“We need to be thinking more broadly and at a system level where the hospital or health care system leverages the electronic health record systems,” he said. “Most of them are sophisticated enough to incorporate simple drug-drug interaction information, so if you try to prescribe someone Paxlovid and it’s a heart transplant patient who is on immunosuppressive therapy or a patient on a blood thinner, then it should give you a warning ... or at least give them a link to our paper or other valuable resources.

“If someone is on a blood thinner and the blood thinner level goes up by ninefold, we can only imagine what we would be dealing with,” Dr. Ganatra said. “So, these interactions should be taken very seriously and I think it’s worth the time and investment.”

Nirmatrelvir/ritonavir (Paxlovid) has been a game changer for high-risk patients with early COVID-19 symptoms but has significant interactions with commonly used cardiovascular medications, a new paper cautions.

COVID-19 patients with cardiovascular disease (CVD) or risk factors such as diabetes, hypertension, and chronic kidney disease are at high risk of severe disease and account for the lion’s share of those receiving Paxlovid. Data from the initial EPIC-HR trial and recent real-world data also suggest they’re among the most likely to benefit from the oral antiviral, regardless of their COVID-19 vaccination status.

Blogging is a great way to capture the attention of new patients and anyone interested in the diagnoses and procedures you specialize in. Health information is one of the most popular topics people search for online. Starting a physician blog can provide your practice with promotional and marketing benefits that you may have a difficult time finding elsewhere. A blog can be an effective way to drive traffic to your website, establish yourself as an authority or expert in a particular area, and stay on the radar with your patients. However, there are a few things you should think about before you start.

Start by determining what you want to accomplish. Do you want to reach quantitative milestones, like a certain number of followers, or are you looking to increase your website traffic from potential patients? One goal will probably be to augment the health knowledge of your patients. Decide early on what your benchmarks will be and how you will track them.

Next, determine who your potential readers are. Initially, most will probably be local (your existing patient base and their family and friends), but your audience may expand geographically as your blog gains in popularity.

By now, you probably realize that blogging will require a significant commitment, over and above the time needed to write the content. Decide whether you have the time and energy to take this on yourself, or whether help will be needed. Ideally, you should have one person in charge of all your social media efforts, so that everything is consistent and has the same voice. That person can be in-house, or you can outsource to any of the many companies that administer blogs and other media functions. (As always, I have no financial interest in any company or service mentioned in this column.)

The advantage of hiring an outside administrator is that a professionally designed blog will be far more attractive and polished than anything you could build yourself. Furthermore, an experienced designer will employ “search engine optimization” (SEO), meaning that content will be created using key words and phrases that will make it readily visible to search engine users.

You can leave design and SEO to the pros, but don’t delegate the content itself; as captain of the ship you are responsible for all the facts and opinions on your blog. You may not be up to writing everything yourself, but anything you don’t write personally needs to be scrutinized by you personally to make sure that it is factually accurate and reflects your personal view. And remember that, once it’s online, it’s online forever; consider the ramifications of anything you post on any site – yours or others – before hitting the “send” button. “The most damaging item about you,” one consultant told me, “could well be something you post yourself.” Just ask any of several prominent politicians who have famously sabotaged their own careers online.

That said, don’t be shy about creating content. Patients appreciate factual information, but they value your opinions too. Give people content that will be of interest or benefit to them. This can include health-related tips, reminders, suggestions, whatever. If they are interested in it, they will keep reading and may even share it with others. You should also write about subjects – medical and otherwise – that interest you personally. If you have expertise in a particular field, be sure to write about that.

Your practice is a local business, so localize your blog to attract people from your area. Be sure to include local city keywords in your writing. You may also want to post about local events in which your practice is involved.

Try to avoid political diatribes. While most physicians have strong political opinions, and some are not shy about expressing them, there are many venues that are more appropriate for those discussions than medical blogs. Also avoid outright sales pitches. It’s fine to describe procedures that you offer, but aggressive solicitation will only turn readers off.

Keep any medical advice in general terms; don’t use any specific examples that might make a patient identifiable and generate a HIPAA violation.

If you are having trouble growing your readership, use your practice’s Facebook page to push blog updates into patients’ feeds. Additionally, track Twitter hashtags that are relevant to your practice, and use them to find existing online communities with an interest in your blog’s topics.

The term myasthenia gravis (MG), from the Latin “grave muscle weakness,” denotes the rare autoimmune disorder characterized by dysfunction at the neuromuscular junction.¹ The clinical presentation of the disease is variable but most often includes ocular symptoms, such as ptosis and diplopia, bulbar weakness, and muscle fatigue upon exertion.^2,3 Severe symptoms can lead to myasthenic crisis, in which generalized weakness can affect respiratory muscles, leading to possible intubation or death.^2,3

Onset of disease ranges from childhood to late adulthood, and largely depends on the subgroup of disease and the age of the patient.⁴ Although complications from MG can arise, treatment methods have considerably reduced the risk of MG-associated mortality, with the current rate estimated to be 0.06 to 0.89 deaths for every 1 million person-years (that is, approximately 5% of cases).^3,5
 

Pathophysiology

MG is caused by binding of autoimmune antibodies to postsynaptic receptors and by molecules that prevent signal transduction at the muscle endplate.^2,4,6,7 The main culprit behind the pathology (in approximately 85% of cases) is an autoimmune antibody for the acetylcholine receptor (AChR); however, other offending antibodies – against muscle-specific serine kinases (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), and the proteoglycan agrin – are known, although at a lower frequency (in approximately 15% of cases).^4,8 These antibodies prevent signal transmission by blocking, destroying, or disrupting the clustering of AChR at the muscle endplate, a necessary step in formation of the neuromuscular junction.^4,8,9

• AChR antibody-positive.
• MuSK antibody-positive.
• LRP4 antibody-positive.
• Seronegative MG.

Classifying MG into subgroups gives insight into the functional expectations and potential treatment options for a given patient, although expectations can vary.²

Regrettably, the well-understood pathophysiology, diagnosis, and prognosis of MG have limited investigation and development of new therapies. Additionally, mainstay treatments, such as thymectomy and prednisone, work to alleviate symptoms for most patients, and have also contributed to periods of slowed research and development. However, treatment of refractory MG has, in recent years, become the subject of research on new therapeutic options, aimed at treating heterogeneous disease populations.¹⁰

In this review, we discuss the diagnosis of, and treatment options for, MG, and provide an update on promising options in the therapeutic pipeline.

Diagnosis

Distinguishing MG from other neuromuscular junction disorders is a pertinent step before treatment. Although the biomarkers discussed in this section are sensitive for making a diagnosis of MG, additional research is needed to classify seronegative patients who do not have circulating autoantibodies that are pathognomonic for MG.¹¹

Consensus on treatment standards

A quantitative assessment of best options for treating MG was conducted by leading experts,¹³ who reached consensus that primary outcomes in treating MG are reached when a patient presents without symptoms or limitations on daily activities; or has only slight weakness or fatigue in some muscles.¹³

Emerging therapies

Although conventional treatments for MG are well-established, 10% to 20% of MG patients remain refractory to therapeutic intervention.²¹ These patients are more susceptible to myasthenic crisis, which can result in hospitalization, intubation, and death.²¹ As mentioned, rescue therapies, including plasmapheresis and IVIg, are imperative to achieve remission of refractory MG, but such remission is unsustainable. Risks associated with these therapies, including contraindications and patient comorbidity, and their limited availability have prevented plasmapheresis and IVIg from being reliable interventions.¹²

These shortcomings, along with promising results from randomized clinical trials of newer modes of pharmacotherapeutic intervention, have increased interest in new therapies for MG. For example, complement pathway and neonatal Fc receptor (FcRn) inhibitors have recently shown promise in removing pathogenic autoimmune antibodies.¹⁸

Efgartigimod. FcRn is of interest in treating generalized MG because of its capacity to recycle and extend the half-life of IgG.²² Efgartigimod is a high-affinity FcRn inhibitor that simultaneously reduces IgG recycling and increases its degradation.²² This therapy is unique: it is highly selective for IgG, whereas other FcRn therapies are nonspecific, causing an undesirable decrease in other immunoglobulin and albumin levels.²² In December 2021, the Food and Drug Administration approved efgartigimod for the treatment of AChR-positive generalized MG.²³

Zilucoplan is a subcutaneously administered complement inhibitor that has completed phase 3 clinical trials.^18,24 The drug works by inhibiting cleavage of proteins C5a and C5b in the terminal complement complex, a necessary step in forming cytotoxic pores on targeted cells.^18,24 Zilucoplan also prevents tissue damage and destruction of signal transmission at the postsynaptic membrane.²⁵ Clinical trials have already established improvement in the Quantitative MG Score and the Myasthenia Gravis Activities of Daily Living Score in patients with generalized MG.^18,24

Zilucoplan is similar to eculizumab, but targets a different binding site, allowing for treatment of heterogeneous MG populations who have a mutation in the eculizumab target antigen.²⁶ Additionally, due to specific drug-body interactions, parameters for treatment using zilucoplan are broader than for therapies such as eculizumab. In a Zilucoplan press-release, the complement inhibitor showed statistically significant improvement in the treatment group of generalized, AChR-positive MG patients compared to the placebo group. Tolerability and safety was also a favorable finding in this study. However, a similar rate of treatment-emergent adverse events were recorded between the treatment group (76.7%) and placebo group (70.5%) which could indicate that the clinical application of this treatment is still forthcoming.²⁷ If zilucoplan is approved by the FDA, it will be used earlier in disease progression and for a larger subset of patients.²⁶

Nipocalimab is another immunoglobulin G1, FcRn antibody that reduces IgG levels in blood.^27,28 A phase 2 clinical study in patients with AChR-positive or MuSK antibody–associated MG showed that 52% of patients who received nipocalimab had a significant reduction in the Myasthenia Gravis Activities of Daily Living Score 4 weeks after infusion.²⁸ Phase 3 studies for adults with generalized MG are underway and are expected to conclude in April 2026.²⁹
 

Looking forward

Despite emerging therapies aimed at treating IgG in both refractory and nonrefractory MG, there is still a need for research into biomarkers that further differentiate disease. Developing research into new biomarkers, such as circulating microRNAs, gives insight into the promise of personalized medicine, which can shape the landscape of MG and other disorders.³⁰ As of August 2022, only two clinical trials are slated for investigation into new biomarkers for MG.

Although the treatment of MG might have once been considered stagnant, newer expert consensus and novel research are generating optimism for innovative therapies in coming years.

The term myasthenia gravis (MG), from the Latin “grave muscle weakness,” denotes the rare autoimmune disorder characterized by dysfunction at the neuromuscular junction.¹ The clinical presentation of the disease is variable but most often includes ocular symptoms, such as ptosis and diplopia, bulbar weakness, and muscle fatigue upon exertion.^2,3 Severe symptoms can lead to myasthenic crisis, in which generalized weakness can affect respiratory muscles, leading to possible intubation or death.^2,3

Onset of disease ranges from childhood to late adulthood, and largely depends on the subgroup of disease and the age of the patient.⁴ Although complications from MG can arise, treatment methods have considerably reduced the risk of MG-associated mortality, with the current rate estimated to be 0.06 to 0.89 deaths for every 1 million person-years (that is, approximately 5% of cases).^3,5
 

Pathophysiology

MG is caused by binding of autoimmune antibodies to postsynaptic receptors and by molecules that prevent signal transduction at the muscle endplate.^2,4,6,7 The main culprit behind the pathology (in approximately 85% of cases) is an autoimmune antibody for the acetylcholine receptor (AChR); however, other offending antibodies – against muscle-specific serine kinases (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), and the proteoglycan agrin – are known, although at a lower frequency (in approximately 15% of cases).^4,8 These antibodies prevent signal transmission by blocking, destroying, or disrupting the clustering of AChR at the muscle endplate, a necessary step in formation of the neuromuscular junction.^4,8,9

• AChR antibody-positive.
• MuSK antibody-positive.
• LRP4 antibody-positive.
• Seronegative MG.

Classifying MG into subgroups gives insight into the functional expectations and potential treatment options for a given patient, although expectations can vary.²

Regrettably, the well-understood pathophysiology, diagnosis, and prognosis of MG have limited investigation and development of new therapies. Additionally, mainstay treatments, such as thymectomy and prednisone, work to alleviate symptoms for most patients, and have also contributed to periods of slowed research and development. However, treatment of refractory MG has, in recent years, become the subject of research on new therapeutic options, aimed at treating heterogeneous disease populations.¹⁰

In this review, we discuss the diagnosis of, and treatment options for, MG, and provide an update on promising options in the therapeutic pipeline.

Diagnosis

Distinguishing MG from other neuromuscular junction disorders is a pertinent step before treatment. Although the biomarkers discussed in this section are sensitive for making a diagnosis of MG, additional research is needed to classify seronegative patients who do not have circulating autoantibodies that are pathognomonic for MG.¹¹

Consensus on treatment standards

A quantitative assessment of best options for treating MG was conducted by leading experts,¹³ who reached consensus that primary outcomes in treating MG are reached when a patient presents without symptoms or limitations on daily activities; or has only slight weakness or fatigue in some muscles.¹³

Emerging therapies

Although conventional treatments for MG are well-established, 10% to 20% of MG patients remain refractory to therapeutic intervention.²¹ These patients are more susceptible to myasthenic crisis, which can result in hospitalization, intubation, and death.²¹ As mentioned, rescue therapies, including plasmapheresis and IVIg, are imperative to achieve remission of refractory MG, but such remission is unsustainable. Risks associated with these therapies, including contraindications and patient comorbidity, and their limited availability have prevented plasmapheresis and IVIg from being reliable interventions.¹²

These shortcomings, along with promising results from randomized clinical trials of newer modes of pharmacotherapeutic intervention, have increased interest in new therapies for MG. For example, complement pathway and neonatal Fc receptor (FcRn) inhibitors have recently shown promise in removing pathogenic autoimmune antibodies.¹⁸

Efgartigimod. FcRn is of interest in treating generalized MG because of its capacity to recycle and extend the half-life of IgG.²² Efgartigimod is a high-affinity FcRn inhibitor that simultaneously reduces IgG recycling and increases its degradation.²² This therapy is unique: it is highly selective for IgG, whereas other FcRn therapies are nonspecific, causing an undesirable decrease in other immunoglobulin and albumin levels.²² In December 2021, the Food and Drug Administration approved efgartigimod for the treatment of AChR-positive generalized MG.²³

Zilucoplan is a subcutaneously administered complement inhibitor that has completed phase 3 clinical trials.^18,24 The drug works by inhibiting cleavage of proteins C5a and C5b in the terminal complement complex, a necessary step in forming cytotoxic pores on targeted cells.^18,24 Zilucoplan also prevents tissue damage and destruction of signal transmission at the postsynaptic membrane.²⁵ Clinical trials have already established improvement in the Quantitative MG Score and the Myasthenia Gravis Activities of Daily Living Score in patients with generalized MG.^18,24

Zilucoplan is similar to eculizumab, but targets a different binding site, allowing for treatment of heterogeneous MG populations who have a mutation in the eculizumab target antigen.²⁶ Additionally, due to specific drug-body interactions, parameters for treatment using zilucoplan are broader than for therapies such as eculizumab. In a Zilucoplan press-release, the complement inhibitor showed statistically significant improvement in the treatment group of generalized, AChR-positive MG patients compared to the placebo group. Tolerability and safety was also a favorable finding in this study. However, a similar rate of treatment-emergent adverse events were recorded between the treatment group (76.7%) and placebo group (70.5%) which could indicate that the clinical application of this treatment is still forthcoming.²⁷ If zilucoplan is approved by the FDA, it will be used earlier in disease progression and for a larger subset of patients.²⁶

Nipocalimab is another immunoglobulin G1, FcRn antibody that reduces IgG levels in blood.^27,28 A phase 2 clinical study in patients with AChR-positive or MuSK antibody–associated MG showed that 52% of patients who received nipocalimab had a significant reduction in the Myasthenia Gravis Activities of Daily Living Score 4 weeks after infusion.²⁸ Phase 3 studies for adults with generalized MG are underway and are expected to conclude in April 2026.²⁹
 

Looking forward

Despite emerging therapies aimed at treating IgG in both refractory and nonrefractory MG, there is still a need for research into biomarkers that further differentiate disease. Developing research into new biomarkers, such as circulating microRNAs, gives insight into the promise of personalized medicine, which can shape the landscape of MG and other disorders.³⁰ As of August 2022, only two clinical trials are slated for investigation into new biomarkers for MG.

Although the treatment of MG might have once been considered stagnant, newer expert consensus and novel research are generating optimism for innovative therapies in coming years.
