Patients with multiple sclerosis (MS) treated with the B-cell-depleting medication rituximab who have not yet been vaccinated against COVID-19 should get the initial vaccination as soon as possible but wait to get a booster shot until B-cell levels increase, new research suggests.

In a prospective cohort study, 90% of patients taking rituximab whose B-cell level was at least 40 cells/mcL had a sufficient antibody response to the Pfizer vaccine, whereas among those with lower levels, the antibody response was significantly lower.

Results also showed a wide variation in the length of time needed for adequate B-cell restoration. Some patients needed a year or longer for levels to become adequate.

The findings led the hospital where the study was conducted to suspend rituximab therapy until patients could be vaccinated. The findings also prompted researchers to call for new guidelines on vaccine scheduling that are based on B-cell levels and not on the current criteria of length of time since last treatment.

“It’s meaningless to just go by some recommendation covering time since the last treatment,” study investigator Joachim Burman, MD, PhD, a consultant neurologist at Uppsala University Hospital and an associate professor at Uppsala University, both in Sweden, told this news organization.

“It’s misleading and potentially harmful for patients,” Dr. Burman said.

The findings were published online  in JAMA Network Open.
 

Finding the cutoff

Drugs such as rituximab target CD20, a protein found on the surface of B cells, resulting in B-cell depletion.

Rituximab is the most common MS therapy used in Sweden. The drug is approved in the United States to treat rheumatoid arthritis and some forms of cancer, but it is not approved for treatment of MS.

Prior research showed that antibody response to COVID-19 vaccines was lower in patients receiving B-cell therapy than in the general population. That was not altogether surprising, given the fact that studies have found a similarly weakened antibody response to other vaccines.

But before now, there was no known B-cell threshold sufficient to mount an acceptable antibody response following COVID vaccination.

Researchers enrolled 67 patients in the study. Of those patients, 60 had received rituximab treatment, and seven had not.

Approximately 6 months after the last rituximab dose, the B-cell count was lower than 10/mcL for 40% of patients. In that group, rituximab treatment duration was the only factor significantly associated with slower B-cell mobilization (median duration, 4.0 years, vs. 2.1; P = .002).
 

Close monitoring needed

Six weeks after vaccination with tozinameran, the mRNA vaccine manufactured by Pfizer, 28% of patients failed to generate a sufficient antibody response. Among those patients, the median B-cell count was 22/mcL, versus 51/mcL for the remainder of the cohort (P < .001).

A cutoff value of 40/mcL rendered adequate levels of anti-spike immunoglobulin G antibodies in 90% of patients and a strong response in anti-RBD antibodies in 72%.

Study participants did register an adequate T-cell response to the vaccine, suggesting at least some level of protection.

Because MS patients are at increased risk for serious illness from SARS-CoV-2 infection, the investigators recommend that patients with MS receive their initial COVID vaccines as soon as possible – but that they should hold off on receiving a booster until their B-cell counts reach 40/mcL.

Regarding when a clinician should re-vaccinate, “the results from our study strongly suggest that you should not do that right away or just follow some generic guideline,” Dr. Burman said.

“You should closely monitor the B-cell values, and re-vaccinate once those B- cells hit the level of 40 cells/mcL” he added.

Dr. Burman said he would expect that their findings would hold with the other mRNA vaccine and with any other B-cell therapy.
 

Too soon for B-cell measures?

Commenting for this news organization, Robert J. Fox, MD, staff neurologist at the Mellen Center for MS and vice-chair for research at the Neurological Institute at Cleveland Clinic, Ohio, said the B-cell threshold identified in the study is much higher than what is typically seen in patients who undergo treatment with ocrelizumab, an anti-CD20 B-cell therapy approved in the United States for treating MS.

“Decisions about treatment interval need to balance efficacy in treating MS with safety, including response to vaccines,” said Dr. Fox, who was not involved with the research.

“Given the unknown efficacy of these extended intervals, I don’t think we’re at the point of making management recommendations based upon B-cell counts,” he added.

And yet, Uppsala University Hospital, where the study was conducted, and other centers in Sweden decided to do just that. They suspended administering rituximab to patients with MS until the patients were vaccinated. For patients newly diagnosed with MS, therapy was initiated using another disease-modifying treatment, and for those who were due for a rituximab infusion, that treatment was delayed.

Only one patient experienced a mild MS relapse during the rituximab suspension, and that case went into remission within a week, Dr. Burman reported.

“Ever since the Bar-Or report showing that the humeral response to vaccines is markedly diminished in MS patients treated with anti-CD20 therapies, clinicians have been struggling to balance those safety concerns related to anti-CD20 monoclonal antibody treatments and the clinical benefit of this treatment class,” Dr. Fox said.

“Given the uncharted waters of the COVID pandemic, clinicians made judgments and decisions as best they could, given the paucity of data,” he noted.

“At this point, we don’t know which decisions were right or wrong, but I certainly don’t think we should judge clinicians for making decisions the best they could.”

The study was funded by the Engkvist Foundation, the Marianne and Marcus Wallenberg Foundation, and the Swedish Society for Medical Research. Dr. Burman reported no relevant financial relationships. Dr. Fox has received consulting fees from Genentech/Roche, Biogen, and other companies that promote MS therapies.

In a new risk-assessment document, the European Centre for Disease Prevention and Control summarizes what we currently know about monkeypox and recommends that European countries focus on the identification and management of the disease as well as contract tracing and prompt reporting of new cases of the virus.

Recent developments

From May 15 to May 23, in eight European Union member states (Belgium, France, Germany, Italy, the Netherlands, Portugal, Spain, and Sweden) a total of 85 cases of monkeypox were reported; they were acquired through autochthonous transmission. Current diagnosed cases of monkeypox have mainly been recorded in men who have sexual relations with other men, suggesting that transmission may occur during sexual intercourse, through infectious material coming into contact with mucosa or damaged skin, or via large respiratory droplets during prolonged face-to-face contact.

Andrea Ammon, MD, director of the ECDC, stated that “most current cases have presented with mild symptoms of the disease, and for the general population, the chance of diffusion is very low. However, the likelihood of a further spread of the virus through close contact, for example during sexual activities among people with multiple sexual partners, is considerably increased.”

Stella Kyriakides, European commissioner for health and food safety, added, “I am worried about the increase of cases of monkeypox in the EU and worldwide. We are currently monitoring the situation and, although, at the moment, the probability of it spreading to the general population is low, the situation is evolving. We should all remain alert, making sure that contact tracing and a sufficient diagnostic capacity are in place and guarantee that vaccines and antiviral drugs are available, as well as sufficient personal protective equipment [PPE] for health care professionals.”
 

Routes of transmission

Monkeypox is not easily spread among people. Person-to-person transmission occurs through close contact with infectious material, coming from skin lesions of an infected person, through air droplets in the case of prolonged face-to-face contact, and through fomites. So far, diagnosed cases suggest that transmission can occur through sexual intercourse.

The incubation period is 5-21 days, and patients are symptomatic for 2-4 weeks.

According to the ECDC, the likelihood of this infection spreading is increased among people who have more than one sexual partner. Although most current cases present with mild symptoms, monkeypox can cause severe disease in some groups (such as young children, pregnant women, and immunosuppressed people). However, the probability of severe disease cannot yet be estimated precisely.

The overall risk is considered moderate for people who have multiple sexual partners and low for the general population.
 

Clinical course

The disease initially presents with fever, myalgia, fatigue, and headache. Within 3 days of the onset of the prodromal symptoms, a centrifugal maculopapular rash appears on the site of primary infection and rapidly spreads to other parts of the body. The palms of the hands and bottoms of the feet are involved in cases where the rash has spread, which is a characteristic of the disease. Usually within 12 days, the lesions progress, simultaneously changing from macules to papules, blisters, pustules, and scabs before falling off. The lesions may have a central depression and be extremely itchy.

If the patient scratches them, a secondary bacterial infection may take hold (for which treatment with oral antihistamines is indicated). Lesions may also be present in the oral or ocular mucous membrane. Either before or at the same time as onset of the rash, patients may experience swelling of the lymph nodes, which usually is not seen with smallpox or chickenpox.

The onset of the rash is considered the start of the infectious period; however, people with prodromal symptoms may also transmit the virus.

Most cases in people present with mild or moderate symptoms. Complications seen in endemic countries include encephalitis, secondary bacterial skin infections, dehydration, conjunctivitis, keratitis, and pneumonia. The death rate ranges from 0% to 11% in endemic areas, with fatalities from the disease mostly occurring in younger children.

There is not a lot of information available on the disease in immunosuppressed individuals. In the 2017 Nigerian epidemic, patients with a concomitant HIV infection presented with more severe disease, with a greater number of skin lesions and genital ulcers, compared with HIV-negative individuals. No deaths were reported among seropositive patients. The main sequelae from the disease are usually disfiguring scars and permanent corneal lesions.
 

Treatment

No smallpox vaccines are authorized for use against monkeypox, however the third-generation smallpox vaccine Imvanex (Modified Vaccinia Ankara) has been authorized by the European Medicines Agency (EMA) for the EU market against smallpox and has demonstrated to provide protection in primates.

Old-generation smallpox vaccines have significant side effects, are no longer authorized, and should no longer be used. It is also important to note the lack of safety data for the use of Imvanex in immunocompromised people.

For this reason, National Immunization Technical Advisory Groups have been asked to develop specific guidelines for vaccination in close contacts of patients with monkeypox. The use of a smallpox vaccine for preexposure prophylaxis cannot be considered now, when taking into account the risk-benefit ratio.

In regard to treatment, tecovirimat is the only antiviral drug with an EMA-authorized indication for orthopoxvirus infection.

Brincidofovir is not authorized in the EU but has been authorized by the US Food and Drug Administration. However, availability on the European market is limited somewhat by the number of doses.

According to the ECDC, health care authorities should provide information about which groups should have priority access to treatment.

The use of antivirals for postexposure prophylaxis should be investigated further. Cidofovir is active in vitro for smallpox but has a pronounced nephrotoxicity profile that makes it unsuitable for first-line treatment.

The ECDC document also proposes an interim case definition for epidemiologic reporting. Further indications will also be provided for the management of monkeypox cases and close contacts. Those infected should remain in isolation until the scabs have fallen off and should, above all, avoid close contact with at-risk or immunosuppressed people as well as pets.

Most infected people can remain at home with supportive care.
 

Prevention

Close contacts for cases of monkeypox should monitor the development of their symptoms until 21 days have passed from their most recent exposure to the virus.

Health care workers should wear appropriate PPE (gloves, water-resistant gowns, FFP2 masks) during screening for suspected cases or when working with confirmed cases. Laboratory staff should also take precautions to avoid exposure in the workplace.

Close contacts of an infected person should not donate blood, organs, or bone marrow for at least 21 days from the last day of exposure.

Finally, the ECDC recommends increasing proactive communication of the risks to increase awareness and provide updates and indications to individuals who are at a greater risk, as well as to the general public. These messages should highlight that monkeypox is spread through close person-to-person contact, especially within the family unit, and also potentially through sexual intercourse. A balance, however, should be maintained between informing the individuals who are at greater risk and communicating that the virus is not easily spread and that the risk for the general population is low.
 

Human-to-animal transmission

A potential risk for human-to-animal transmission exists in Europe; therefore, a close collaboration is required between human and veterinary health care authorities, working together to manage domestic animals exposed to the virus and to prevent transmission of the disease to wildlife. To date, the European Food Safety Authority is not aware of any reports of animal infections (domestic or wild) within the EU.

There are still many unknown factors about this outbreak. The ECDC continues to closely monitor any developments and will update the risk assessment as soon as new data and information become available.

If human-to-animal transmission occurs and the virus spreads among animal populations, there is a risk that the disease could become an endemic in Europe. Therefore, human and veterinary health care authorities should work together closely to manage cases of domestic animals exposed to the virus and prevent transmission of the disease to wildlife.

We are currently monitoring the situation and, although, at the moment, the probability of it spreading to the general population is low, the situation is evolving. We should all remain alert, making sure that contact tracing and a sufficient diagnostic capacity are in place and guarantee that vaccines and antiviral drugs are available, as well as sufficient personal protective equipment [PPE] for health care professionals.”
 

Routes of transmission

Monkeypox is not easily spread among people. Person-to-person transmission occurs through close contact with infectious material, coming from skin lesions of an infected person, through air droplets in the case of prolonged face-to-face contact, and through fomites. So far, diagnosed cases suggest that transmission can occur through sexual intercourse.

The incubation period is 5-21 days, and patients are symptomatic for 2-4 weeks.

According to the ECDC, the likelihood of this infection spreading is increased among people who have more than one sexual partner. Although most current cases present with mild symptoms, monkeypox can cause severe disease in some groups (such as young children, pregnant women, and immunosuppressed people). However, the probability of severe disease cannot yet be estimated precisely.

The overall risk is considered moderate for people who have multiple sexual partners and low for the general population.
 

Clinical course

The disease initially presents with fever, myalgia, fatigue, and headache. Within 3 days of the onset of the prodromal symptoms, a centrifugal maculopapular rash appears on the site of primary infection and rapidly spreads to other parts of the body. The palms of the hands and bottoms of the feet are involved in cases where the rash has spread, which is a characteristic of the disease. Usually within 12 days, the lesions progress, simultaneously changing from macules to papules, blisters, pustules, and scabs before falling off. The lesions may have a central depression and be extremely itchy.

If the patient scratches them, a secondary bacterial infection may take hold (for which treatment with oral antihistamines is indicated). Lesions may also be present in the oral or ocular mucous membrane. Either before or at the same time as onset of the rash, patients may experience swelling of the lymph nodes, which usually is not seen with smallpox or chickenpox.

The onset of the rash is considered the start of the infectious period; however, people with prodromal symptoms may also transmit the virus.

Most cases in people present with mild or moderate symptoms. Complications seen in endemic countries include encephalitis, secondary bacterial skin infections, dehydration, conjunctivitis, keratitis, and pneumonia. The death rate ranges from 0% to 11% in endemic areas, with fatalities from the disease mostly occurring in younger children.

There is not a lot of information available on the disease in immunosuppressed individuals. In the 2017 Nigerian epidemic, patients with a concomitant HIV infection presented with more severe disease, with a greater number of skin lesions and genital ulcers, compared with HIV-negative individuals. No deaths were reported among seropositive patients. The main sequelae from the disease are usually disfiguring scars and permanent corneal lesions.
 

Treatment

No smallpox vaccines are authorized for use against monkeypox, however the third-generation smallpox vaccine Imvanex (Modified Vaccinia Ankara) has been authorized by the European Medicines Agency (EMA) for the EU market against smallpox and has demonstrated to provide protection in primates.

Old-generation smallpox vaccines have significant side effects, are no longer authorized, and should no longer be used. It is also important to note the lack of safety data for the use of Imvanex in immunocompromised people.

For this reason, National Immunization Technical Advisory Groups have been asked to develop specific guidelines for vaccination in close contacts of patients with monkeypox. The use of a smallpox vaccine for preexposure prophylaxis cannot be considered now, when taking into account the risk-benefit ratio.

In regard to treatment, tecovirimat is the only antiviral drug with an EMA-authorized indication for orthopoxvirus infection.

Brincidofovir is not authorized in the EU but has been authorized by the US Food and Drug Administration. However, availability on the European market is limited somewhat by the number of doses.

According to the ECDC, health care authorities should provide information about which groups should have priority access to treatment.

The use of antivirals for postexposure prophylaxis should be investigated further. Cidofovir is active in vitro for smallpox but has a pronounced nephrotoxicity profile that makes it unsuitable for first-line treatment.

The ECDC document also proposes an interim case definition for epidemiologic reporting. Further indications will also be provided for the management of monkeypox cases and close contacts. Those infected should remain in isolation until the scabs have fallen off and should, above all, avoid close contact with at-risk or immunosuppressed people as well as pets.

Most infected people can remain at home with supportive care.
 

Prevention

Close contacts for cases of monkeypox should monitor the development of their symptoms until 21 days have passed from their most recent exposure to the virus.

Health care workers should wear appropriate PPE (gloves, water-resistant gowns, FFP2 masks) during screening for suspected cases or when working with confirmed cases. Laboratory staff should also take precautions to avoid exposure in the workplace.

Close contacts of an infected person should not donate blood, organs, or bone marrow for at least 21 days from the last day of exposure.

Finally, the ECDC recommends increasing proactive communication of the risks to increase awareness and provide updates and indications to individuals who are at a greater risk, as well as to the general public. These messages should highlight that monkeypox is spread through close person-to-person contact, especially within the family unit, and also potentially through sexual intercourse. A balance, however, should be maintained between informing the individuals who are at greater risk and communicating that the virus is not easily spread and that the risk for the general population is low.
 

Human-to-animal transmission

A potential risk for human-to-animal transmission exists in Europe; therefore, a close collaboration is required between human and veterinary health care authorities, working together to manage domestic animals exposed to the virus and to prevent transmission of the disease to wildlife. To date, the European Food Safety Authority is not aware of any reports of animal infections (domestic or wild) within the EU.

There are still many unknown factors about this outbreak. The ECDC continues to closely monitor any developments and will update the risk assessment as soon as new data and information become available.

If human-to-animal transmission occurs and the virus spreads among animal populations, there is a risk that the disease could become an endemic in Europe. Therefore, human and veterinary health care authorities should work together closely to manage cases of domestic animals exposed to the virus and prevent transmission of the disease to wildlife.

The biggest cancer conference in the world is back in person after 2 years online during the COVID pandemic. And it appears many are eager to attend the American Society of Clinical Oncology annual meeting in person now that they can.

By early May, ASCO already had 30,000 registrations, of which 80% were in person – there were 27,000 hotel reservations.

“That’s almost identical to where we were in terms of numbers in 2019 at the same point in time,” Julie Gralow, MD, chief medical officer at ASCO, said in an interview.

These figures, which are from May 11, are likely to increase. In past years, there has been an upswing in registrations right before the meeting starts.

The annual meeting begins on Friday, June 3, and runs until Tuesday, June 7. It will be held in Chicago, yet again, in the vast McCormick Place, sections of which were transformed into field hospital wards when the pandemic hit in 2020.

But the meeting will also continue to be transmitted virtually, as it has been for the past 2 years, for those not attending in person.

“I do think that the hybrid model will move forward,” Dr. Gralow said. “We can get a lot of attendees, especially from very distant places, who can’t travel, or can’t easily travel, and we have learned how to make that experience better for them as well.”

Attendees can also change their minds if, for example, rising numbers of COVID cases as the meeting nears put them off traveling. “We are allowing people to change to virtual. So I think there may be a little bit of that, depending on what happens to COVID in different parts of the world,” Dr. Gralow commented.

For those who do attend, the organization is “doing the best that we can to keep people safe,” said Dr. Gralow, who was previously a professor of global health and is now a breast medical oncologist and clinical trialist.

To attend in person, ASCO is mandating proof of vaccination (which in the United States means two doses of the COVID vaccine). “If you prove in advance that you are vaccinated, we will send you your badge, so you don’t have to stand in line,” she added.

“As far as masks go, we are saying right now that we are complying with Chicago’s rules, which mean there is no mandatory indoor masking,” she continued. “We are recommending masking because this is a group of physicians who treat immunocompromised patients. So we are recommending that.”

This stance has gotten some push-back on Twitter from both physicians and patient advocates, with some surprised that masking is not mandatory.

“I know that ‘mask-optional’ meetings mean most will omit masks; I literally just saw this at my last meeting as one of the few masked MDs,” commented radiation oncologist Fumiko Ladd Chino, MD. She appealed to the organizers with a plea: “There’s still time to change #ASCO22 policies. We’re in it for patient health.”

Patient advocate Manju George, MVSc, PhD, a rectal cancer survivor, was also campaigning for a change in policy by setting up a letter that others could sign, adding that “ASCO leadership is being flooded with pleads from concerned HCPs.”

When asked whether it was considering a change in mask policy, ASCO replied: “As far as health and safety go, the protocols we’ve put in place meet or exceed current [World Health Organization, [Centers for Disease Control and Prevention, and city of Chicago guidelines. ASCO is also closely coordinating with both the city and the convention center and we are actively monitoring local conditions.”

“To protect the health and safety of all meeting attendees, our protocols require attendees to be fully vaccinated and self-test negative for COVID-19 within 48 hours prior to their arrival at the meeting. In addition, we expect all attendees to be masked when indoors and are encouraging regular self-testing. We fully expect members of our community to do their part to help keep everyone safe, and we’re making it easy for attendees to comply with our policies by providing medical-grade masks as well as both rapid antigen and [polymerase chain reaction] COVID-19 tests,” the organization said.

There will also be a notification system so attendees can select how they identify for closeness, with red meaning stand back, no hugs, no handshakes; yellow signifying something more intermediate; and green signaling the person is okay with contact with a handshake or a hug. This system has already been used during smaller ASCO subspecialty meetings earlier this year, and feedback from delegates was positive, Dr. Gralow commented.
 

Advancing equitable care

The theme of the 2022 meeting, chosen by ASCO President Everett Vokes, MD, is advancing equitable cancer care through innovation.

It builds on the theme of equity from 2021, chosen by previous president Lori Pierce, MD, which was “Equity: Every Patient. Every Day. Everywhere.”

Some of this relates to disparities in equity, commented Dr. Gralow. This is the focus of a premeeting press briefing on May 26 that will highlight a few abstracts that focus on disparities and what can be done to address them. One study (abstract 6511) focuses on telemedicine, which was increasingly used during the pandemic, but the results show not all U.S. patient populations could access the specialty care they needed in this way.
 

De-escalation of therapy

De-escalation of therapy is another theme running through the meeting.

“There are some cancers where we have achieved such good outcomes that it is time to look at de-escalating therapy because we know that we are probably way overtreating a component of those patients. ... So we are looking at whether we can find subpopulations where we can back off on therapy,” commented Dr. Gralow.

One example is the LUMINA trial in breast cancer (abstract LBA501), which looked at omitting radiotherapy after surgery. “In standard practice we have already been doing this, not based on solid data, but based on an accumulation of retrospective analyses and similar evidence,” commented Dr. Gralow. This trial tested the approach prospectively, lowered the age range of patients, and better defined which patients were likely to benefit.

Another example is the DYNAMIC trial in colorectal cancer (abstract LBA-100), which looks at omitting chemotherapy based on levels of circulating tumor DNA after surgery. These patients had stage 2 disease and generally do very well with surgery and adjuvant chemotherapy, Dr. Gralow stated. This trial aims to find the subset of patients who could do just as well without the chemotherapy; it may also identify those patients at the other end of the scale, who perhaps need a bit more treatment, she added.
 

Spotlight on innovation

The focus on innovation includes exploring drugs developed outside the United States. One example is nimotuzumab, which is already approved in China for use in nasopharyngeal cancer but is also being explored in other cancer types. At ASCO, data will be presented in patients with KRAS wild-type pancreatic cancer (abstract 4011). This study, like the other trials with nimotuzumab, was conducted in China.

This brings up an important point about the data the Food and Drug Administration requires for new drug approvals, commented Dr. Gralow.

She noted that the FDA recently rejected an application for sintilimab, a drug also developed in China, on the basis that all trial data submitted for approval were from China. The agency said it would like to see multiregional clinical trials and trials that reflect the U.S. cancer population.
 

Advice for attendees

A large trial in a rare cancer promises to establish a new standard of care, where previously a number of different regimens have been used in various parts of the world, and even at different hospitals within the same country. These are the results from an international trial in children and adolescents/young adults with Ewing’s sarcoma (abstract LBA-02). “I have been told by experts in the field that these results will change practice ... [and] will have a global impact,” commented Dr. Gralow.

In addition to the scientific sessions that will see new data, there are a number of educational sessions that will tackle tricky issues that clinicians sometimes face. “Microaggressions, Bias, and Equity in the Workplace” will be discussed in one session, while another promises, “Strategies to Address Moral Distress in Clinicians: What Should We Do When We Don’t Know What to Do?”

There is also a special session featuring the “Cancer Groundshot: Addressing the Global and National Inequities in Cancer Care.” This is a move spearheaded by Bishal Gyawali, MD, PhD, from Brigham and Women’s Hospital, Boston, who was reacting to the lofty goals of the presidential Cancer Moonshot, including the aim of “ending cancer as we know it.” In a blog post in 2016 he suggested “forget the moon; let’s get back to blood and flesh reality on the ground ... [and] research that can be immediately applied to every global community.” He recounts the journey from ‘Blog Post to ASCO Session’ in a recent commentary.

Dr. Gyawali also has some advice for those attending the ASCO annual meeting: Reach out to people you respect, trust that connections will happen, scrutinize the data, listen critically for jargon, and perhaps most importantly, have fun.

“There’s more to life than your job,” he wrote. “Don’t stress. Think about the bigger picture. Think about your patients. And remember, life is beautiful, even when it feels like it isn’t.”

CHICAGO – The COVID pandemic pushed telemedicine forward as a safe, accessible, and more widely reimbursed approach to care delivery for patients with cancer, but uptake of telemedicine was plagued by inequities, a retrospective study suggests.

Before March 2020, only a very small percentage of patients with cancer used telemedicine services.

By November 2021, nearly 16% of patients initiating cancer treatment were using this approach.

However, certain groups were less likely to use telemedicine, in particular, patients who were Black, uninsured, did not live in cities, and were less affluent, noted lead author Jenny S. Guadamuz, PhD, a quantitative scientist at Flatiron Health and a postdoctoral research associate at the University of Southern California, Los Angeles.

The results are concerning because they suggest that telemedicine expansion could widen cancer care disparities, Dr. Guadamuz said. Previous studies found racial disparities in care access and outcomes early on in the pandemic.

“These findings are critically important considering recent efforts to make coverage of telemedicine services permanent, instead of tied to the [Health and Human Services] public health emergency declaration,” she said. “There are also efforts to increase reimbursement rates for telemedicine services by Medicare, several Medicaid programs, and private insurers.”

This study was highlighted at a press briefing held in advance of the American Society of Clinical Oncology annual meeting, where it will be presented at a poster session (abstract 6511).

ASCO President Everett E. Vokes, MD, said telemedicine is “an important tool to communicate with patients” but that it is important to consider the “digital divide.”

He also emphasized the need “to expand and learn to use telehealth not in a crisis but as part of our regular care moving forward.” In July 2021, as telemedicine services were expanding, ASCO released practice recommendations specific to telehealth and oncology.

“Telemedicine can improve access to timely cancer care, but, as this study points out, telemedicine must be available equitably, so that every patient can access the care they need and deserve,” he said in a press statement.
 

Study details

For the study, Dr. Guadamuz and colleagues assessed telemedicine uptake by nearly 27,000 patients in a Flatiron electronic health record–derived deidentified database of patients who initiated treatment for any of 21 common cancers at about 280 community oncology clinics between March 2020 and November 2021.

They found that Black patients were significantly less likely than were White patients to use telemedicine (13.2% vs. 15.6%; odds ratio [OR], 0.82), as were patients without documented insurance, compared with those who were well insured (11.6% vs. 16.4%; OR, 0.68).

Those in rural and suburban areas were less likely than were those in urban areas to use telemedicine (9.7% and 13.0% vs. 17.7%; ORs, 0.50 and 0.69, respectively), and those in less affluent vs. more affluent areas were also less likely to use telemedicine (10.6% vs. 23.6%, OR, 0.39).

Dr. Guadamuz noted that the differences remained statistically significant after adjustment for clinical characteristics and that racial inequities were seen across cancer types and over time.

Future work should assess other potential characteristics associated with telemedicine inequities, evaluate whether health care delivered via telemedicine is of similar quality as in-person services, and determine the types of practice that are providing telemedicine more equitably to their patients, she concluded.

Increasing social services spending by 10% led to improved survival for non-Hispanic Black adults with cancer, according to new research.

Five-year overall survival increased among non-Hispanic Black patients by 2.02% in conjunction with a 10% increase in spending. In addition, there was a decrease in racial disparities in survival between non-Hispanic Black patients and White patients for many types of cancers.

However, public welfare spending had no real impact on the overall 5-year survival for the entire cohort (0.25 % per 10% increase in spending; P = .78) or for non-Hispanic White patients (0.52% per 10% increase in spending, P = .58).

“We know from prior research that outcomes are worse for minorities,” said lead author Justin Michael Barnes, MD, from the department of radiation oncology at Washington University in St. Louis, Mo. “It’s thought that some of the differences are related to impaired access to health care for minorities, which is related to social determinants of health. This includes socioeconomic factors, educational attainment, place of residence, as well as environmental stressors.

“Our data show that greater state welfare expenditures were associated with greater 5-year survival among Black patients and decreased Black–White disparities,” said Dr. Barnes. “I think these data are thought provoking, but they certainly aren’t the end. I see these data as a proof-of-concept project.”

Dr. Barnes reported the findings at a press conference held in advance of the annual meeting of the American Society of Clinical Oncology, during which the study will be presented (Abstract 6509).
 

Improved 5-year survival in Black patients

For the study, Dr. Barnes and colleagues evaluated the association of 5-year overall survival and public welfare spending in 2,925,550 individuals aged 18 years and older who were diagnosed with cancer during the period 2007-2016. The cohort was drawn from the Surveillance, Epidemiology, and End Results Program. In addition, annual state spending data were obtained from the U.S. Census Bureau. The team examined survival outcomes by race and ethnicity as well as by cancer site. The investigators accounted for factors such as age, sex, metropolitan residence, state, county-level income and education, insurance status, cancer site, stage at diagnosis, and year of diagnosis.

Much of public welfare spending was related to Medicaid but also included programs that provide subsidy assistance for individuals, such as Supplemental Security Income.

As compared with White patients, the 5-year overall survival rate was 10.8% lower among non-Hispanic Black patients. But there was a 4.46% (P for interaction <.001) narrowing of the 5-year overall survival disparity in non-Hispanic Black patients in comparison with White patients per 10% increase in spending, or a 42% closure of the 10.8% disparity.

Regarding specific cancer types, increased public welfare spending was associated with a narrowing of the 5-year overall survival disparity between Black patients and non-Hispanic White patients for the following cancers: breast (a 6.15% survival increase for Black patients led to a 39% closing of the disparity), cervix (a 11.9% survival increase led to a 46% closing of the disparity), colorectum (a 4.42% survival increase led to a 48% closing of the disparity), head and neck (a 9.41% survival increase led to a 38% closing of the disparity), liver (a 7.02% survival increase led to a 49% closing of the disparity), ovary (an 8.95% survival increase led to a 41% closing of the disparity), bladder (an 8.18% survival increase led to a 44% closing of the disparity), and uterus (a 14.1% survival increase led to a 40% closing of the disparity).

“Some type of public welfare seems to be helping improve oncologic outcomes for some of our most socioeconomically at-risk patients, but we don’t know the specifics,” Dr. Barnes concluded. “Additional work is needed to identify the most influential public health expenditures. If we can do this, we can more rigorously evaluate state-level policies and their association with cancer outcomes.”
 

Public welfare improves outcomes

Weighing in on the data, Sarah P. Cate, MD, director, Special Surveillance and Breast Program, Mount Sinai Health System, New York, noted that racial disparities have been identified in many areas of health care and with respect to many diseases. “In the world of oncology, time to diagnosis and treatment significantly impacts overall survival,” she told this news organization. “Many studies are currently underway to investigate why certain ethnic groups have worse cancer outcomes.”

This study is important, she noted, in that it “highlights a discrete source of correcting these disparities in a large group of patients. Obviously there are multiple barriers to care, but increased public welfare spending in oncology should decrease some of these disparities.”

Julie R. Gralow, MD, ASCO’s chief medical officer and executive vice president, commented that it is known that state public welfare spending can mitigate structural racism and at least partially address social determinants of health, such as financial stability, education, place of residence, and insurance status. “This research found that states that increased their public health spending improved overall survival in Black patients with a variety of solid tumors and also resulted in a decrease in racial disparities in survival,” she said. “This important data provides clear support for the benefits of investment in public welfare spending at the state level, including Medicaid expansion.”

The study did not receive funding. Dr. Barnes and Dr. Cate have disclosed no relevant financial relationships. Dr. Gralow has relationships with Genentech, AstraZeneca Hexal, Puma BioTechnology, Roche, Novartis, Seagen, and Genomic Health.

NEW ORLEANS – Patients with new-onset schizophrenia often ask psychiatrist Stephen R. Marder, MD, whether they’ll need to be on medications forever to treat the disorder. Now, he said, research is showing that the answer isn’t always yes.

In many cases, “it’s an open question” whether lifelong medical treatment is needed, said Dr. Marder, a professor at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles, who spoke in a presentation about schizophrenia treatment at the annual meeting of the American Psychiatric Association.

According to Dr. Marder, research about relapses suggests that there may be a subpopulation of patients who can come off antipsychotics and remain in remission or partial remission. “The problem,” he said, “is that group is very hard to identify.”

Indeed, he highlighted a 2017 study that suggested perhaps 20% of patients with schizophrenia may remain stable over the long term after stopping medication. The study noted choosing the best candidates isn’t simple, as “we do not have clinical measures or biomarkers that allow us to identify them prospectively. Because relapses and delays in the treatment of psychosis have been associated with poorer outcomes, there may be risk associated with withholding or discontinuing medication.”

There are more complications. There’s some evidence that antipsychotic drugs reduce brain volume, Dr. Marder said. But on the other hand, each psychotic episode can itself be harmful. “There is clear evidence that for each psychotic episode, they can take longer to improve, and they need higher doses.”

What to do? “My suggestion for most patients is to keep them on a relatively mild dose of an antipsychotic,” Dr. Marder said, “then to have a gradual decrease in the dose. I’ve done it in many patients.”

Which drug is best over the long term – oral or long-acting injectable antipsychotics? “It’s a hard question to answer because if you rely on randomized clinical trials – with patients who signed consent and are willing to be in a study like that – the subjects are sometimes not the ones who benefit the most from the long-acting drugs. So for many of the randomized clinical trials, the data was incomplete, and it was hard to make the case.”

But if you combine meta-analyses and cohort studies, as a 2021 study did, “you come up with a really clear answer: LAIs [long-acting injectables] are superior. They lead to a superior outcomes when it comes to rehospitalization and psychotic relapse,” Dr. Marder said.

That study reported that “LAIs were more beneficial than oral antipsychotics in 60 [18.3%] of 328 comparisons, not different in 252 [76.8%] comparisons, and less beneficial in 16 [4.9%] comparisons.”
 

More schizophrenia treatment pearls

People with schizophrenia – including those who aren’t on medication – face three times the risk of developing type 2 diabetes as the general population, “maybe because there’s a shared genetic risk for both disorders,” Dr. Marder said. “Those of you who have a lot of schizophrenia patients, I suspect you’re monitoring if they’re treating their type 2 diabetes and their obesity.”

Which antipsychotics are the best option for these patients? He highlighted a 2020 systematic review and meta-analysis that offers helpful insight into connections between 18 drugs and factors like weight and cholesterol.

Dr. Marder added that “if somebody has an elevation in their triglycerides or [hemoglobin] A1c in one single fasting blood glucose during the first 6 weeks of treatment, even if they haven’t been rated, it suggests that they’re developing insulin resistance.” At that point, he said, it’s a good idea to reconsider the medication choice.

Also, he said, keep in mind that “there’s substantial evidence that metformin is the appropriate treatment for patients who begin to demonstrate insulin resistance. It also works sometimes for weight loss.”

Exercise in people with schizophrenia can pay important dividends. A 2016 meta-analysis suggests that “not only does exercise for people with schizophrenia lead to better cardiovascular health, it’s good for the brain and improves cognitive functioning,” Dr. Marder said. “It’s not easy sometimes to get people with schizophrenia to exercise, but it’s many times worth the effort.”

Dr. Marder reported consulting for Boehringer Ingelheim, Lundbeck, Otsuka, Roche, Neurocrine, Sunovion, Newron, Merck, and Biogen; editor of UptoDate and Schizophrenia Bulletin Open; and research support from Boehringer Ingelheim.

Dr. Marder added that “if somebody has an elevation in their triglycerides or [hemoglobin] A1c in one single fasting blood glucose during the first 6 weeks of treatment, even if they haven’t been rated, it suggests that they’re developing insulin resistance.” At that point, he said, it’s a good idea to reconsider the medication choice.

Also, he said, keep in mind that “there’s substantial evidence that metformin is the appropriate treatment for patients who begin to demonstrate insulin resistance. It also works sometimes for weight loss.”

Exercise in people with schizophrenia can pay important dividends. A 2016 meta-analysis suggests that “not only does exercise for people with schizophrenia lead to better cardiovascular health, it’s good for the brain and improves cognitive functioning,” Dr. Marder said. “It’s not easy sometimes to get people with schizophrenia to exercise, but it’s many times worth the effort.”

Dr. Marder reported consulting for Boehringer Ingelheim, Lundbeck, Otsuka, Roche, Neurocrine, Sunovion, Newron, Merck, and Biogen; editor of UptoDate and Schizophrenia Bulletin Open; and research support from Boehringer Ingelheim.
 

NEW ORLEANS – Patients with new-onset schizophrenia often ask psychiatrist Stephen R. Marder, MD, whether they’ll need to be on medications forever to treat the disorder. Now, he said, research is showing that the answer isn’t always yes.

In many cases, “it’s an open question” whether lifelong medical treatment is needed, said Dr. Marder, a professor at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles, who spoke in a presentation about schizophrenia treatment at the annual meeting of the American Psychiatric Association.

According to Dr. Marder, research about relapses suggests that there may be a subpopulation of patients who can come off antipsychotics and remain in remission or partial remission. “The problem,” he said, “is that group is very hard to identify.”

Indeed, he highlighted a 2017 study that suggested perhaps 20% of patients with schizophrenia may remain stable over the long term after stopping medication. The study noted choosing the best candidates isn’t simple, as “we do not have clinical measures or biomarkers that allow us to identify them prospectively. Because relapses and delays in the treatment of psychosis have been associated with poorer outcomes, there may be risk associated with withholding or discontinuing medication.”

There are more complications. There’s some evidence that antipsychotic drugs reduce brain volume, Dr. Marder said. But on the other hand, each psychotic episode can itself be harmful. “There is clear evidence that for each psychotic episode, they can take longer to improve, and they need higher doses.”

What to do? “My suggestion for most patients is to keep them on a relatively mild dose of an antipsychotic,” Dr. Marder said, “then to have a gradual decrease in the dose. I’ve done it in many patients.”

Which drug is best over the long term – oral or long-acting injectable antipsychotics? “It’s a hard question to answer because if you rely on randomized clinical trials – with patients who signed consent and are willing to be in a study like that – the subjects are sometimes not the ones who benefit the most from the long-acting drugs. So for many of the randomized clinical trials, the data was incomplete, and it was hard to make the case.”

But if you combine meta-analyses and cohort studies, as a 2021 study did, “you come up with a really clear answer: LAIs [long-acting injectables] are superior. They lead to a superior outcomes when it comes to rehospitalization and psychotic relapse,” Dr. Marder said.

That study reported that “LAIs were more beneficial than oral antipsychotics in 60 [18.3%] of 328 comparisons, not different in 252 [76.8%] comparisons, and less beneficial in 16 [4.9%] comparisons.”
 

More schizophrenia treatment pearls

Trauma surgeons are in the tough position of seeing victims just after gun violence across the United States, and they have some advice.

Their strategies can work regardless of where you stand on the Second Amendment of the Constitution, said Patricia Turner, MD. “Our proposals are embraced by both gun owners and non–gun owners alike, and we are unique in that regard.”

These “implementable solutions” could prevent the next massacre, Dr. Turner, executive director of the American College of Surgeons, said during a news briefing the group sponsored on June 2.

“Our future – indeed all of our futures – depend on our ability to find durable, actionable steps that we can implement tomorrow to save lives,” she said.
 

Firsthand perspective

“Sadly I’m here today as a trauma surgeon who has cared for two of the largest mass shootings in modern U.S. history,” said Ronald Stewart, MD, chair of the department of surgery at University Hospital in San Antonio, Texas.

Dr. Stewart treated victims of the 2017 Sutherland Springs First Baptist Church shooting – where 27 people died, including the shooter – and the recent Uvalde school shooting, both in Texas.

“The injuries inflicted by high-velocity weapons used at both of these attacks are horrific. A high-capacity, magazine-fed automatic rifle such as the AR-15 causes extremely destructive tissue wounds,” he said.

One of the group’s proposals is to increase the regulation of high-velocity weapons, including AR-15s.

“These wounds are horribly lethal at close range, and sadly, most victims do not survive long enough to make it to a trauma center,” Dr. Stewart said.

On a positive note, “all of our current [Uvalde] patients are improving, which really brings us joy in this dark time,” he said. “But all of them have a long road to deal with recovery with both the physical and emotional impact of their injuries.”

Jeffrey Kerby, MD, agreed.

“Trauma surgeons see the short-term physical effects of these injuries and watch patients struggle with the long-term impact of these wounds,” said Dr. Kerby, director of trauma and acute care surgery at the University of Alabama at Birmingham.
 

Surgeons feel ‘profound impact’ of shootings

“Firearm violence has a profound impact on surgeons, and we are the undisputed subject matter experts in treating the tragic results,” said Patrick Bailey, MD, medical director for advocacy at the American College of Surgeons.

“This impacts surgeons as well,” said Dr. Kerby, chair of the Committee on Trauma for the surgeons’ group. “We are human, and we can’t help but share in the grief, the pain, and the suffering that our patients endure.

“As a pediatric surgeon ... I have too often witnessed the impact of firearm violence, and obviously, the devastation extends beyond the victims to their families,” he said. “To put it succinctly, in our culture, parents are not supposed to be put in a position of burying their children.”
 

A public health crisis

“It’s important to recognize that we’ve been talking about a public health approach,” said Eileen Bulger, MD, acting chief of the trauma division at the University of Washington in Seattle. That strategy is important for engaging both firearm owners and communities that have a higher risk for firearm violence, she said.

A committee of the American College of Surgeons developed specific recommendations in 2018, which are still valid today. The group brought together surgeons from across the U.S. including “passionate firearm owners and experts in firearm safety,” Dr. Bulger said.

The committee, for example, agreed on 10 specific recommendations “that we believe are bipartisan and could have an immediate impact in saving lives.”

“I’m a lifelong gun owner,” Dr. Bailey said, emphasizing that the team’s process included participation and perspective from other surgeons “who, like me, are also gun owners, but gun owners who also seek to reduce the impact of firearm violence in our country.”

The recommendations address these areas:

• Gun ownership
• Firearm registration
• Licensure
• Education and training
• Ownership responsibilities
• Mandatory reporting and risk reduction
• Safety innovation and technology
• Research
• The culture of violence
• Social isolation and mental health

For example, “we currently have certain classes of weapons with significant offensive capability,” Dr. Bulger said, “that are appropriately restricted and regulated under the National Firearms Act as Class 3 weapons.”

This group includes fully automatic machine guns, explosive devices, and short-barrel shotguns.

“We recommend a formal reassessment of the firearms designated within each of these national firearms classifications,” Dr. Bulger said.

For example, high-capacity, magazine-fed semiautomatic rifles, such as the AR-15, should be considered for reclassification as NFA Class 3 firearms, or they should get a new designation with tighter regulation.

The ACS endorses formal firearm safety training for all new gun owners. Also, owners who do not provide reasonably safe firearm storage should be held responsible for events related to the discharge of their firearms, Dr. Bulger said. And people who are deemed an imminent threat to themselves or others through firearm ownership should be temporarily or permanently restricted, with due process.
 

Research and reporting reforms

The ACS is also calling for research on firearm injuries and firearm injury prevention to be federally funded, Dr. Bulger said. The research should be done in a nonpartisan manner, she said.

“We have concerns that the manner and tone in which information is released to the public may lead to copycat mass killers,” she said. “The ACS recommends that law enforcement officials and the press take steps to eliminate the notoriety of the shooter, for example.”

Dr. Bulger also addressed the mental health angle. “We encourage recognition of mental health warning signs and social isolation by teachers, counselors, peers, and parents.” When identified, immediate referral to professionals is needed.

In addition to these recommendations, another team from the American College of Surgeons has published an overview of ways to address the inequities that contribute to violence. “We advocate for federal funding to support the development of hospital-based and community programs for violence intervention and prevention,” Dr. Bulger said.

Dr. Bailey said that as a gun owner himself, he thinks other gun owners would support these recommendations.

“I do not believe that the steps recommended ... pose undue burden on the rights of individual gun owners,” he said.
 

The time is now

Most firearm injuries are not from mass shooting events, Dr. Kerby said.

“My own trauma center has seen a 40% increase in the number of firearm injuries just in the last 2 years,” he added, “and these numbers continue to grow.”

The Prevention of Asthma Exacerbations Using Dupilumab in Urban Children and Adolescents (PANDA) trial was launched in order to examine the effects of treatment on children with poorly controlled allergic asthma who live in low-income urban environments in the United States, according to the National Institute of Allergy and Infectious Diseases.

Black and Hispanic children who live in these environments are at particularly high risk for asthma and are prone to attacks. These children and adolescents often have many allergies and are exposed to both high levels of indoor allergens and traffic-related pollution, which can make their asthma even more difficult to control, according to a June 2 NIAID press release.

PANDA is a multicenter, double-blind, placebo-controlled, randomized trial of dupilumab adjunctive therapy for the reduction of asthma exacerbations in urban children and adolescents 6-17 years with T2-high exacerbation-prone asthma. Approximately 240 participants will be randomized 2:1 to one of two study arms: 1) guidelines-based asthma treatment plus dupilumab, or 2) guidelines-based asthma treatment plus placebo. The planned study treatment will continue for 1 year with an additional 3 months of follow-up following completion of study treatment, according to the study details.

In an earlier study, NIAID-supported investigators identified numerous networks of genes that are activated together and are associated with asthma attacks in minority children and adolescents living in low-income urban settings

“We need to find out how well approved asthma drugs work for disadvantaged children of color living in urban areas, and whether biological markers can help predict how the drugs affect their asthma,” NIAID director Anthony S. Fauci, MD, said in the release. “The PANDA trial is an important step toward these goals.”

Participant criteria for the study include children of either sex, ages 6-17 years, who live in prespecified urban areas. Participants must have a diagnosis of asthma and must have had at least two asthma exacerbations in the prior year (defined as a requirement for systemic corticosteroids and/or hospitalization). At the screening visit, participants must have the following requirements for asthma controller medication: For children ages 6-11 years: treatments with at least fluticasone 250 mcg dry powder inhaler (DPI) one puff twice daily or its equivalent; for children ages 12 years and older, treatment with at least fluticasone 250 mcg plus long-acting beta agonist (LABA) DPI one puff twice daily or its equivalent.

Scientists have confirmed that a receptor long suspected to be linked to lupus is, in fact, a major driver of the autoimmune disease for at least some subset of patients, according to a study recently published in Nature. Researchers discovered the crucial role of toll-like receptor 7 (TLR7) because of a rare mutation in a pediatric patient with systemic lupus erythematosus (SLE) who had a particularly severe presentation.

“Sometimes it’s valuable to find these very severe cases where there is one mutation that has a strong effect because if we understand how those mutations work, the lessons we learn can generally tell us about disease mechanisms,” explained senior author Carola G. Vinuesa, MD, PhD, of the Centre for Personalised Immunology at Australian National University in Canberra and The Francis Crick Institute in London.

“It’s quite difficult to find one mutation that can alone cause the entire disease,” Dr. Vinuesa added, but what it reveals about how the disease develops may lead to more effective targeted therapies than the immune suppressants most often used to treat lupus currently.

The mutation they found was in the TLR7 gene that encodes the TLR7 protein. TLR7 is a receptor used by immune cells to identify viral RNA so they can fight off viral infections, including COVID-19. But if the body’s own genetic material binds to TLR7 in susceptible individuals, it can lead to an overproduction of type 1 interferons, which are cytokines that trigger or exacerbate the immune reactions that lead to lupus symptoms. The TLR7 gene occurs on the X chromosome, which may explain men’s greater susceptibility to COVID-19 and the greater incidence of lupus in women, who have two X chromosomes instead of the one that men have, Dr. Vinuesa said.

Previous research had shown an association between TLR7 and lupus, but this new study is the first to provide definitive proof that a TLR7 mutation by itself can directly cause human lupus. After discovering the variant in the patient, Dr. Vinuesa’s team used CRISPR to edit the genome of a mouse model and introduce the same mutation the patient had. “And they developed full-blown disease, just with this one single base-pair substitution – 1 letter in the 3 billion letters of the genome,” Dr. Vinuesa said. “It tells us that these receptors are not just there to recognize viral RNA, that in some circumstances, they could be triggered by our own nucleic acids.”
 

One pathway among many?

The finding does not mean that every lupus patient has this mutation, which remains rare, but suggests that overactivity in this receptor already reported in many lupus patients may be causally related to disease, Dr. Vinuesa said.

Noa Schwartz, MD, an assistant professor of medicine at Albert Einstein College of Medicine, New York, and director of the Montefiore-Einstein Institute for Lupus Care and Research, said in an interview that lupus is thought of as a syndrome, a collection of different but similar diseases that don’t necessarily have a single cause. But finding a single gene mutation that could potentially lead to lupus is an important piece of the puzzle, said Dr. Schwartz, who was not involved in the study. Based on past research in mice models, “we’ve hypothesized that TLR7 is important in humans as well, but this is the last nail in the coffin.”

One of the key questions this finding has prompted is how many patients’ disease results from TLR7 activity. “Because of the evidence from Ignacio Sanz’s group demonstrating TLR7 overactivity in a significant fraction of SLE patients, we believe that it is probably going to be pretty important,” Dr. Vinuesa said. “My feeling is that it is going to be quite a central pathway in lupus pathogenesis, if not the central pathway.”

Dr. Schwartz was more cautious, noting that it is probably important for a subset of patients but may “have a limited effect on the general lupus population.” While it’s not yet clear how large that subset is, it is possible it will include people with cutaneous lupus, those with primarily dermatologic symptoms.

“Hydroxychloroquine works particularly well for cutaneous manifestations of lupus, and one of the ways that works is by inhibiting TLR7 and TLR9, so this [finding] potentially matters for skin disease and lupus, but it’s very early,” Dr. Schwartz said. If it does turn out that TLR7 activity is particularly associated with cutaneous lupus, it may mean therapies with fewer side effects, she said. “Specifically for cutaneous lupus, the concept of suppressing the entire immune system for skin illness sometimes feels, especially to patients, very extreme, so they are [patients] who directed therapy could be so especially relevant for.”

Laura Lewandowski, MD, an assistant clinical investigator and head of the lupus genomics and global health disparities unit at the National Institute of Arthritis and Musculoskeletal and Skin Disease, described this study as particularly remarkable in the way it revealed the mechanism leading to lupus symptoms.

“As whole genome sequencing becomes faster and less expensive, more and more people are employing them in their studies,” most of which report changes in certain genes, Dr. Lewandowski said. “One of the most striking findings about this paper was that they took it to the next step and did a really elegant study on the exact way this gain-of-function TLR7 mutation leads to the autoimmunity that we see in lupus. The detail of mechanism in this paper is really unique.”
 

A step toward personalized medicine

Dr. Lewandowski is part of a team that recently presented a poster related to genomic sequencing in lupus patients at the annual meeting of the Childhood Arthritis and Rheumatology Research Alliance. Her study reported on the whole genome sequencing of patients with childhood-onset SLE who were already enrolled in the CARRA Lupus Registry. Children with lupus may be more likely than adults to have rare genetic variants, so a registry of childhood-onset SLE patients with fully sequenced genomes provides an opportunity to look for single-gene mutations specifically linked to lupus, said Dr. Lewandowski, who has recently begun a research collaboration with Dr. Vinuesa.

“As we move forward and more and more patients are included in these studies, we will understand a little bit more about the genetic architecture of patients who have rare variations leading to disease, or even common variations,” Dr. Lewandowski said about the intersection between her research and Dr. Vinuesa’s study. The more data they gather, the more they can explore the possible interactions of rare and common variants that play a role in SLE as well as what environmental triggers, such as viral infection or pollution exposure, might tip someone into having an autoimmune disease. “We’re just starting to peek under the hood,” Dr. Lewandowski said.

If further research can reveal the relative contribution of genetics to the disease and what those genetic drivers are, it may allow for greater precision in therapies and “ultimately improve the quality of life for our patients, the ultimate goal of all of these studies,” Dr. Lewandowski said.

Drugs that target TLR7 already exist for other indications, and clinical trials have already begun to see if these TLR7 inhibitors benefit lupus patients.

“If the clinical trials work, this will be quite a nice, targeted therapy with potentially much less side effects than other therapies on the market at the moment,” Dr. Vinuesa said. She is cautiously hopeful, saying it’s likely to make an impact on lupus treatment, but it’s too early to say precisely how much.

“It allows us to understand the disease mechanisms a little bit better and to try and assess what percentage of patients’ disease can be explained by overactivity in this receptor,” Dr. Vinuesa said. She thinks it’s possible that TLR7 over activation may be relevant to other systemic autoimmune diseases as well, such as Sjögren’s syndrome, rheumatoid arthritis, or juvenile dermatomyositis, but it will take more studies to find out.

“Right now, we have medicines that broadly inhibit the immune system and aren’t as targeted, but we have a lot more clinical and scientific work to do before we move this field forward for lupus patients,” Dr. Lewandowski said. “This is one case where they were able to find the exact molecular defect, and it’s not the end of the path of precision medicine — it’s the beginning.”

Dr. Vinuesa, Dr. Schwartz, and Dr. Lewandowski reported no disclosures.

Scientists have confirmed that a receptor long suspected to be linked to lupus is, in fact, a major driver of the autoimmune disease for at least some subset of patients, according to a study recently published in Nature. Researchers discovered the crucial role of toll-like receptor 7 (TLR7) because of a rare mutation in a pediatric patient with systemic lupus erythematosus (SLE) who had a particularly severe presentation.

“Sometimes it’s valuable to find these very severe cases where there is one mutation that has a strong effect because if we understand how those mutations work, the lessons we learn can generally tell us about disease mechanisms,” explained senior author Carola G. Vinuesa, MD, PhD, of the Centre for Personalised Immunology at Australian National University in Canberra and The Francis Crick Institute in London.
