Doug Flora, MD, knows the value of early cancer detection because it helped him survive kidney cancer 5 years ago. But as a medical oncologist and hematologist, and the executive medical director of oncology services at St. Elizabeth Healthcare in Edgewood, Ky., he also knows that a new era of early cancer detection testing poses big challenges for his network of six hospitals and 169 specialty and primary care offices throughout Kentucky, Ohio, and Indiana.

Multicancer early detection (MCED) tests are finally a reality and could be a potential game changer because they can screen for the possibility of up to 50 different cancers in asymptomatic individuals with one blood draw. They represent one of the fastest growing segments in medical diagnostics with a projected value of $2.77 billion by 2030, according to the market research firm Grand View Research.

These tests are different from traditional liquid biopsies, which are designed to identify actionable gene mutations to help inform treatment decisions of patients already diagnosed with cancer. Instead, MCED tests work to detect fragments of circulating free DNA that have been shed by tumors and released into the bloodstream. Detecting these cancer signals could indicate that an individual has cancer well before they ever develop symptoms.

For some cancer types, particularly those commonly diagnosed at advanced stages or those without general population screening tests, MCED testing could have a significant impact.

In its new report, Grand View Research highlights nine “prominent players” active in the MCED market; of these, two have been granted breakthrough device designation by the Food and Drug Administration: OverC MCDBT by Burning Rock on Jan. 3, 2023, and Galleri by Grail in 2019. Galleri was launched in June 2021 and can be obtained with a prescription at a cost of $949.

Yet, while patients are asking for these tests and primary care physicians are prescribing them, oncologists are grappling with how to manage the first patients whose tests tell them they may have cancer.

Ordering the tests may seem straightforward, but in reality, it is not. In fact, they are so new that most health systems have no internal guidelines for physicians. Guidelines would address when the tests should be prescribed, and whether a patient should undergo more testing or be referred to an oncologist.
 

Clinical trials underway

There are currently at least 17 clinical trials underway to investigate the performance and clinical utility of MCED tests. Six of these involve Grail, including NHS-Galleri, the largest study to date of 140,000 participants in the United Kingdom where participants will be followed for 3 years with annual visits at 12 and 24 months. And, the National Cancer Institute is spearheading a clinical trial of its own, according to a search of ClinicalTrials.gov.

In September 2022, Grail presented findings from its pivotal PATHFINDER study at the annual meeting of the European Society of Medical Oncology. Researchers reported that cancer signals were detected in 1.4% (92) of 6,621 participants enrolled in the study. Of the 92, 35 people were diagnosed with 36 cancers: 19 were solid tumors (2 oropharyngeal, 5 breast, l liver, 1 intrahepatic bile duct, 2 colon/rectum, 2 prostate, 1 lung, 1 pancreas, 1 small intestine, 1 uterus, 1 ovary and 1 bone) and 17 hematologic cancers (1 plasma cell myeloma/disorders, 2 lymphoid leukemia, 2 Waldenström’s macroglobulinemia, and 12 lymphoma).

Almost half of newly diagnosed cases were cancers in stage 1 or 2. Of stage 1 cancers, three were solid tumors and four were hematologic cancers. Of stage 2 cancers, three were solid tumors and four were hematologic cancers. All other cancers were in stage 3 and 4 or were listed as recurrent or no stage. Deb Schrag, MD, MPH, chair of the department of medicine at Memorial Sloan Kettering Cancer Center in New York, who presented the results from PATHFINDER at ESMO, reported that, of all diagnosed cancers, only breast, colon/rectum, prostate, and lung have established screening protocols.

The findings were so striking that the meeting scientific co-chair, Fabrice André, MD, PhD, told ESMO the oncology field must prepare for an onslaught of new patients.

“Within the next 5 years, we will need more doctors, surgeons and nurses with more diagnostic and treatment infrastructures to care for the rising number of people who will be identified by multicancer early detection tests,” said Dr. André, who is director of research at Gustave Roussy Cancer Center, Villejuif, France, and future president of ESMO (2025-2026). “We need to involve all stakeholders in deciding new pathways of care. We need to agree who will be tested and when and where tests will be carried out, and to anticipate the changes that will happen as a result of these tests.”

But first, he urged, the need for comparative trials “across all types of cancer to find out if having an early detection test affects morbidity and mortality. We also need to know how the tests benefit patients, and how to discuss the results with them,” Dr. André said.
 

Demand may burden health systems

Dr. Flora suggested that companies like Grail are rushing their product to market without conducting long-term sizable clinical trials.

“These diagnostic companies are a billion dollar publicly traded or venture capital-funded companies that are losing millions of dollars a quarter as they’re scaling up these tests. So, there is some pressure on the sales forces ... to start moving product long before the science has met our lowest areas for entry,” Dr. Flora said. “They are aggressively marketing to a primary care audience that knows nothing about MCEDs. It’s a sales-driven development solving a problem we all believe is real, but we don’t know if it actually solves the problem.”

There are many unanswered questions, he said. Among these include whether the tests do indeed extend survival. “What they’re suggesting – that is if the blood test detects it – that we’re going to save your life. That’s not yet been proven. This is where the providers are pushing back against these industry types to say: ‘This is the wild west right now.’ It’s very irresponsible to go out there and try to sell hundreds of millions of dollars of product to doctors who have never studied genetics,” Dr. Flora said.

Grail’s chief medical officer Jeff Venstrom, MD, however, said physicians don’t need a background in genetic testing to order or interpret Galleri because it’s not a genetic test. Genetic tests look for genetic variants associated with cancer risk, which Galleri does not. MCED tests rely on genomic profiling to identify alterations in tumors.

“Maybe there’s still confusion in the market, which is common for new technologies when they’re initially launched. This is not a 23andMe test. We do not report germline mutations that have implications for cancer risk. We’re using this blood sample to test for the presence or absence of a cancer signal. The test result is very clear and simple: One area of the report says ‘yes’ or ‘no.’ It is a binary result that says if a signal is detected or not. The second provides additional information around where that signal could be coming from,” he said.

Galleri could fill a huge unmet need in cancer prevention, Dr. Venstrom said. Not only could it detect cancer at an earlier stage, but it could serve as a screening tool for cancers like pancreatic cancer in which screening is not available.

The test is not intended to replace standard of care screening, he said. The ordering provider should have a conversation with the patient about overall cancer risk. “Are you smoking? What’s your risk of obesity-associated cancers? Do you have a family history of cancer? I think this should all be in the context of a good conversation around preventative care,” he said.
 

Planning and prep in Boston

In Boston, Aparna Parikh, MD, an oncologist who specializes in gastrointestinal cancers, agreed that MCED testing has forced her team at the Mass General Cancer Center global cancer care program to think outside of the box.

“We’re a major academic center and it’s not easy [because] this is all uncharted territory,” she said. “We all recognize there are more tests coming, and they are here to stay. As a health system, we have to be ready to manage not only the tests, but patient anxieties, and all the complexities that come with it. We just don’t know yet how to best navigate.”

Although Dr. Parikh’s center has set up a working group tasked with organizing an outpatient clinic for patients with positive MCED tests, the current system is haphazard.

“Right now, it gets bounced around between people,” she explained. “Sometimes, patients are getting referred to the oncology team rather than the primary care team to try to sort out where the cancer signal is coming from, that is, if it’s not immediately obvious. No one really knows who should be the right person to own it,” Dr. Parikh said. While the test is supposed to give tissue-specific results, “it’s not perfect” and sometimes imaging and other work-ups are needed to locate the source of the signa.

“A group of four or five oncologists get looped in and then we’re trying to sort it out on a case-by-case basis, but understanding that with more and more tests coming, that kind of ad hoc approach isn’t going to be sufficient. We need a happy medium between the primary care and the disease specific oncologist, someone who can kind of help think through the diagnostic workup until they have a cancer diagnosis to get them to the right place,” Dr. Parikh said.

Dr. Venstrom said Grail is committed to providing support to clinicians in these situations. “We’re doing everything we can with our medical education forums. We have this pretty intense and extensive postpositive suite of resources,” he explained. “Some of our doctors on staff call the ordering provider within 24 hours just to clarify if there are any questions or confusion from the report. For example, if it suggests the signal is coming from the lung, we provide additional support around additional workups.”
 

Out-of-pocket test may widen disparities in care

With the exception of a few health insurance companies that have committed to covering some of the cost for the test, Galleri is an out-of-pocket expense.

Dr. Venstrom acknowledged that broad insurance coverage for the Galleri test remains a hurdle, although “we’ve secured coverage for a handful of companies of self-insured employers and forward-thinking insurers.” This includes partnerships with Point32Health, and Alignment Health, among others, he said.

There is also growing support among more than 400 cancer organizations for the Multi-Cancer Early Detection Screening Coverage Act to accelerate coverage for Medicare beneficiaries. “We are constantly trying to understand the evidence that’s needed for payors to make sure that we get the broadest access possible for this test,” he said.
 

The first positive test result

Back at St. Elizabeth Healthcare where they’ve only seen one positive MCED test result thus far, Dr. Flora is more concerned about patients giving informed consent before they even get the test. “When the reps started hammering our primary care doctors, we sent communiques throughout the system saying that we would very much like to regulate this to make sure that before our patients receive accidental harm, that they at least have a conversation with somebody who understands the test,” he explained.

All 15 patients who requested the test at the hospital were first required to discuss the implications with a genetic counselor who is part of the system. “We are really pro–cancer screening,” he said, but added his hospital is “not pumped” about the Galleri test. “We’re being very cautious about overstatements made by sales guys to our primary care doctors, so we’re letting our own precision medicine people handle it.”

There’s a similar system in place at Community Health Network, a nonprofit health system with nine hospitals and 1,300 employee providers throughout Central Indiana. Patrick McGill, MD, a primary care physician and chief analytics officer for the network says they have streamlined patients with positive tests through their high-risk oncology clinic. “They don’t go straight to a medical oncologist which I know some systems are struggling with,” he said. “They get additional testing, whether it’s imaging they might need or other lab testing. We’ve had a few lung positives, and a few leukemia positives which might go straight to medical oncology. I think we had one breast that was positive so she got additional breast imaging.”

Through its foundation, CHN will offer 2,000 tests free of charge. “We decided to take cost off the table with this funding,” Dr. McGill said. “A lot of health systems I talk to are always concerned that insurance doesn’t cover it and it’s cost prohibitive. Is it creating additional disparities because only people who can afford it can get the test?”

Dr. Schrag serves as an uncompensated advisor for Grail. Previously, while with the Dana-Farber Cancer Institute, she received research funding from Grail.

With the exception of a few health insurance companies that have committed to covering some of the cost for the test, Galleri is an out-of-pocket expense.

Dr. Venstrom acknowledged that broad insurance coverage for the Galleri test remains a hurdle, although “we’ve secured coverage for a handful of companies of self-insured employers and forward-thinking insurers.” This includes partnerships with Point32Health, and Alignment Health, among others, he said.

There is also growing support among more than 400 cancer organizations for the Multi-Cancer Early Detection Screening Coverage Act to accelerate coverage for Medicare beneficiaries. “We are constantly trying to understand the evidence that’s needed for payors to make sure that we get the broadest access possible for this test,” he said.
 

The first positive test result

Back at St. Elizabeth Healthcare where they’ve only seen one positive MCED test result thus far, Dr. Flora is more concerned about patients giving informed consent before they even get the test. “When the reps started hammering our primary care doctors, we sent communiques throughout the system saying that we would very much like to regulate this to make sure that before our patients receive accidental harm, that they at least have a conversation with somebody who understands the test,” he explained.

All 15 patients who requested the test at the hospital were first required to discuss the implications with a genetic counselor who is part of the system. “We are really pro–cancer screening,” he said, but added his hospital is “not pumped” about the Galleri test. “We’re being very cautious about overstatements made by sales guys to our primary care doctors, so we’re letting our own precision medicine people handle it.”

There’s a similar system in place at Community Health Network, a nonprofit health system with nine hospitals and 1,300 employee providers throughout Central Indiana. Patrick McGill, MD, a primary care physician and chief analytics officer for the network says they have streamlined patients with positive tests through their high-risk oncology clinic. “They don’t go straight to a medical oncologist which I know some systems are struggling with,” he said. “They get additional testing, whether it’s imaging they might need or other lab testing. We’ve had a few lung positives, and a few leukemia positives which might go straight to medical oncology. I think we had one breast that was positive so she got additional breast imaging.”

Through its foundation, CHN will offer 2,000 tests free of charge. “We decided to take cost off the table with this funding,” Dr. McGill said. “A lot of health systems I talk to are always concerned that insurance doesn’t cover it and it’s cost prohibitive. Is it creating additional disparities because only people who can afford it can get the test?”

Dr. Schrag serves as an uncompensated advisor for Grail. Previously, while with the Dana-Farber Cancer Institute, she received research funding from Grail.

A new drug application for a first-in-class photodynamic (PDT) therapy for treating early-stage cutaneous T-cell lymphoma (CTCL) has been submitted to the Food and Drug Administration based on phase 3 findings published in JAMA Dermatology.

The treatment employs an ointment formulation of synthetic hypericin (HyBryte), a photosensitizer, that is preferentially absorbed into malignant cells and activated with visible light – rather than ultraviolet light – approximately 24 hours later. Investigators saw significant clinical responses in both patch and plaque type lesions and across races during the 24-week placebo-controlled, double-blinded, phase 3, randomized clinical trial.

“Traditional phototherapy, ultraviolet B phototherapy, has a limited depth of penetration, so patients with thicker plaque lesions don’t respond as well ... and UVB phototherapy typically is less effective in penetrating pigmented skin,” Ellen J. Kim, MD, lead author of the FLASH phase 3 trial, said in an interview.

Visible light in the yellow-red spectrum (500-650 nm) “penetrates deeper into the skin” and is nonmutagenic in vitro, so “theoretically it should have a much more favorable long-term safety profile,” said Dr. Kim, a dermatologist at the University of Pennsylvania, Philadelphia.

Currently, she said, the risk of secondary malignancies inherent with UV PDT, including melanoma, is a deterrent for some patients, especially “patients with really fair skin and a history of skin cancer.”

Hypericin PDT also seems well suited for use with an at-home light unit. “In our field, it’s not about which therapy is [universally] better or best, but a matter of what works best for each patient at that moment in time, depending on the side-effect profile and other issues such as access,” Dr. Kim said. “It will be great to have another option for an incurable disease that requires chronic management.”

Mycosis fungoides (MF)/CTCL is considered an orphan disease, and the treatment has received orphan drug and fast track designations from the FDA, and orphan designation from the European Medicines Agency, according to a press release from its developer, Soligenix. The company is anticipating potential approval in the second half of 2023 and is targeting early 2024 for a U.S. launch, the statement said.

Phase 3 results

The pivotal trial involved 169 patients at 39 academic and community-based U.S. medical centers and consisted of several 6-week cycles of twice-weekly treatment punctuated by 2-week breaks. In cycle 1, patients were randomized 2:1 to receive hypericin or placebo treatment of three index lesions. Cycle 2 involved the crossover of placebo patients to active treatment of index lesions, and cycle 3 (optional) involved open-label treatment of all desired lesions (index and nonindex).

The trial defined the primary endpoint in phase 1 as 50% or greater improvement in the modified Composite Assessment of Index Lesion Severity score – a tool that’s endorsed by U.S. and international MF/CTCL specialty group consensus guidelines. For cycles 2 and 3, open-label response rates were secondary endpoints. Responses were assessed after 2-week rest periods to allow for treatment-induced skin reactions to subside.

After one cycle of treatment, topical hypericin PDT was more effective than placebo (an index lesion response rate of 16% vs. 4%; P =.04). The index lesion response rate with treatment increased to 40% after two cycles and 49% after three cycles. All were statistically significant changes.

Response rates were similar in patch and plaque-type lesions and regardless of age, sex, race, stage IA versus IB, time since diagnosis, and number of prior therapies. Adverse events were primarily mild application-site skin reactions. No serious drug-related adverse events occurred, Dr. Kim said, and “we had a low drop-out rate overall.”
 

Into the real world

The 24-week phase 3 trial duration is short, considering that “typically, phototherapy takes between 4 to 24 months [to achieve] full responses in CTCL,” Dr. Kim said in the interview.

So with real-world application, she said, “we’ll want to see where the overall response peaks with longer treatment, what the effects are of continuous treatment without any built-in breaks, and whether we will indeed see less skin cancer development in patients who are at higher risk of developing skin cancers from light treatment.”

Such questions will be explored as part of a new 4-year, 50-patient, open-label, multicenter study with the primary aim of investigating home-based hypericin PDT therapy in a supervised setting, said Dr. Kim, principal investigator of this study. Patients who are doing well after 6 weeks of twice-weekly therapy will be given at-home light units to continue therapy and achieve 1 year of treatment with no breaks. They will be monitored with video-based telemedicine.

“Long term, having a home unit should really improve patient access and compliance and hopefully effectiveness,” Dr. Kim said. Based on the phase 3 experience, “we think that continuous treatment will be well tolerated and that we may see greater responses.”

On Dec. 19, Soligenix announced that enrollment had begun in a phase 2a study of synthetic hypericin for treating patients with mild to moderate psoriasis.

First described in 2020 by researchers from the U.S. National Institutes of Health, VEXAS syndrome is a systemic autoinflammatory disease of undefined origin. Its name is an acronym: Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic. The prevalence of this syndrome is unknown, but it is not so rare. As it is an X-linked disease, men are predominantly affected.

First identification

The NIH team screened the exomes and genomes of 2,560 individuals. Of this group, 1,477 had been referred because of undiagnosed recurrent fevers, systemic inflammation, or both, and 1,083 were affected by atypical, unclassified disorders. The researchers identified 25 men with a somatic mutation in the ubiquitin-like modifier activating enzyme 1 (UBA1) gene, which is involved in the protein ubiquitylation system. This posttranslational modification has a pleiotropic function that likely explains the clinical heterogeneity seen in VEXAS patients: regulation of protein turnover, especially those involved in the cell cycle, cell death, and signal transduction. Ubiquitylation is also involved in nonproteolytic functions, such as assembly of multiprotein complexes, intracellular signaling, inflammatory signaling, and DNA repair.

Clinical presentation

The clinicobiological presentation of VEXAS syndrome is very heterogeneous. Typically, patients present with a systemic inflammatory disease with unexplained episodes of fever, involvement of the lungs, skin, blood vessels, and joints. Molecular diagnosis is made by the sequencing of UBA1.

Most patients present with the characteristic clinical signs of other inflammatory diseases, such as polyarteritis nodosa and recurrent polychondritis. But VEXAS patients are at high risk of developing hematologic conditions. Indeed, the following were seen among the 25 participants in the NIH study: macrocytic anemia (96%), venous thromboembolism (44%), myelodysplastic syndrome (24%), and multiple myeloma or monoclonal gammopathy of undetermined significance (20%).

In VEXAS patients, levels of serum inflammatory markers are increased. These markers include tumor necrosis factor, interleukin-8, interleukin-6, interferon-inducible protein-10, interferon-gamma, C-reactive protein. In addition, there is aberrant activation of innate immune-signaling pathways.

In a large-scale analysis of a multicenter case series of 116 French patients, researchers found that VEXAS syndrome primarily affected men. The disease was progressive, and onset occurred after age 50 years. These patients can be divided into three phenotypically distinct clusters on the basis of integration of clinical and biological data. In the 58 cases in which myelodysplastic syndrome was present, the mortality rates were higher. The researchers also reported that the UBA1 p.Met41L mutation was associated with a better prognosis.
 

Treatment data

VEXAS syndrome resists the classical therapeutic arsenal. Patients require high-dose glucocorticoids, and prognosis appears to be poor. The available treatment data are retrospective. Of the 25 participants in the NIH study, 40% died within 5 years from disease-related causes or complications related to treatment. Among the promising therapeutic avenues is the use of inhibitors of the Janus kinase pathway.

Because of the high out-of-pocket costs of new-to-market neurologic drugs that are of similar benefit as older agents, only a small percentage of patients with neurologic disorders have access to these cutting-edge medications, new research shows.

“Our study of people with neurologic conditions found that fewer than 20% were being treated with new medications,” study author Brian C. Callaghan, MD, with University of Michigan Health in Ann Arbor, said in a statement.

“For new, high-cost medications that have similar effectiveness to older drugs, limited use is likely appropriate. However, future studies are needed to look into whether the high costs are barriers to those new medications that can really make a difference for people living with neurologic disease,” Dr. Callaghan said.

The study was published online in Neurology.
 

Most expensive drugs

Using insurance claims data, the investigators compared the utilization and costs of new-to-market drugs from 2014 to 2018 with those for existing guideline-supported medications for treating 11 neurologic conditions.

The new drugs included:

• erenumab, fremanezumab, and galcanezumab for migraine.
• ocrelizumab and peginterferon beta-1a for multiple sclerosis (MS).
• pimavanserin and safinamide for Parkinson’s disease.
• droxidopa for orthostatic hypertension.
• eculizumab for myasthenia gravis (MG).
• edaravone for amyotrophic lateral sclerosis (ALS).
• deutetrabenazine and valbenazine for Huntington’s disease and tardive dyskinesia.
• patisiran and inotersen for transthyretin amyloidosis (ATTR).
• eteplirsen and deflazacort for Duchenne disease.
• nusinersen for spinal muscular atrophy (SMA).

Utilization of new drugs was modest – they accounted for one in five prescriptions for every condition except tardive dyskinesia (32% for valbenazine), the researchers noted.

Mean out-of-pocket costs were significantly higher for the new medications, although there was large variability among individual drugs.

The two most expensive drugs were edaravone, for ALS, with a mean out-of-pocket cost of $713 for a 30-day supply, and eculizumab, for MG, which costs $91 per month.

“For new-to-market medications, the distribution of out-of-pocket costs were highly variable and the trends over time were unpredictable compared with existing guideline-supported medications,” the authors reported.

They noted that potential reasons for low utilization of newer agents include delay in provider uptake and prescriber and/or patient avoidance because of high cost.

Given that most of the new neurologic agents offer little advantage compared with existing treatments – exceptions being new drugs for SMA and ATTR – drug costs should be a key consideration in prescribing decisions, Dr. Callaghan and colleagues concluded.

One limitation of the study is that follow-up time was short for some of the recently approved medications. Another limitation is that the number of people in the study who had rare diseases was small.
 

Revolution in neurotherapeutics

“We are living in a time when new treatments bring hope to people with neurologic diseases and disorders,” Orly Avitzur, MD, president of the American Academy of Neurology, said in a statement.

“However, even existing prescription medication can be expensive and drug prices continue to rise. In order for neurologists to provide people with the highest quality care, it is imperative that new drugs are accessible and affordable to the people who need them,” Dr. Avitzur added.

Writing in a linked editorial, A. Gordon Smith, MD, professor and chair, department of neurology, Virginia Commonwealth University, Richmond, said there is a revolution in neurotherapeutics, with particularly robust growth in new drug approvals for orphan diseases (those affecting < 200,000 Americans).

“This study adds to a growing literature indicating rising drug prices are a threat to the health care system. No matter how effective a disease-modifying therapy may be, if a patient cannot afford the cost, it doesn’t work,” Dr. Smith wrote.

He added that neurologists must be “diligent in assessing for financial toxicity and appropriately tailor individual treatment recommendations. We must insist on development of point-of-care tools to accurately estimate each patient’s potential financial toxicity including RTBT [real-time benefit tools].

“Neurologists’ primary obligation is to the individual patient, but we are also compelled to support access to high-quality care for all people, which requires advocacy for appropriate policy reforms to ensure value based and fair drug pricing and treatment success,” Dr. Smith added.

The study was funded by the American Academy of Neurology Health Services Research Subcommittee. Dr. Callaghan consults for a PCORI grant, DynaMed, receives research support from the American Academy of Neurology, and performs medical/legal consultations, including consultations for the Vaccine Injury Compensation Program. Dr. Smith has disclosed no relevant financial relationships.

• deutetrabenazine and valbenazine for Huntington’s disease and tardive dyskinesia.
• patisiran and inotersen for transthyretin amyloidosis (ATTR).
• eteplirsen and deflazacort for Duchenne disease.
• nusinersen for spinal muscular atrophy (SMA).

Utilization of new drugs was modest – they accounted for one in five prescriptions for every condition except tardive dyskinesia (32% for valbenazine), the researchers noted.

Mean out-of-pocket costs were significantly higher for the new medications, although there was large variability among individual drugs.

The two most expensive drugs were edaravone, for ALS, with a mean out-of-pocket cost of $713 for a 30-day supply, and eculizumab, for MG, which costs $91 per month.

“For new-to-market medications, the distribution of out-of-pocket costs were highly variable and the trends over time were unpredictable compared with existing guideline-supported medications,” the authors reported.

They noted that potential reasons for low utilization of newer agents include delay in provider uptake and prescriber and/or patient avoidance because of high cost.

Given that most of the new neurologic agents offer little advantage compared with existing treatments – exceptions being new drugs for SMA and ATTR – drug costs should be a key consideration in prescribing decisions, Dr. Callaghan and colleagues concluded.

One limitation of the study is that follow-up time was short for some of the recently approved medications. Another limitation is that the number of people in the study who had rare diseases was small.
 

Revolution in neurotherapeutics

“We are living in a time when new treatments bring hope to people with neurologic diseases and disorders,” Orly Avitzur, MD, president of the American Academy of Neurology, said in a statement.

“However, even existing prescription medication can be expensive and drug prices continue to rise. In order for neurologists to provide people with the highest quality care, it is imperative that new drugs are accessible and affordable to the people who need them,” Dr. Avitzur added.

Writing in a linked editorial, A. Gordon Smith, MD, professor and chair, department of neurology, Virginia Commonwealth University, Richmond, said there is a revolution in neurotherapeutics, with particularly robust growth in new drug approvals for orphan diseases (those affecting < 200,000 Americans).

“This study adds to a growing literature indicating rising drug prices are a threat to the health care system. No matter how effective a disease-modifying therapy may be, if a patient cannot afford the cost, it doesn’t work,” Dr. Smith wrote.

He added that neurologists must be “diligent in assessing for financial toxicity and appropriately tailor individual treatment recommendations. We must insist on development of point-of-care tools to accurately estimate each patient’s potential financial toxicity including RTBT [real-time benefit tools].

“Neurologists’ primary obligation is to the individual patient, but we are also compelled to support access to high-quality care for all people, which requires advocacy for appropriate policy reforms to ensure value based and fair drug pricing and treatment success,” Dr. Smith added.

The study was funded by the American Academy of Neurology Health Services Research Subcommittee. Dr. Callaghan consults for a PCORI grant, DynaMed, receives research support from the American Academy of Neurology, and performs medical/legal consultations, including consultations for the Vaccine Injury Compensation Program. Dr. Smith has disclosed no relevant financial relationships.

Because of the high out-of-pocket costs of new-to-market neurologic drugs that are of similar benefit as older agents, only a small percentage of patients with neurologic disorders have access to these cutting-edge medications, new research shows.

“Our study of people with neurologic conditions found that fewer than 20% were being treated with new medications,” study author Brian C. Callaghan, MD, with University of Michigan Health in Ann Arbor, said in a statement.

“For new, high-cost medications that have similar effectiveness to older drugs, limited use is likely appropriate. However, future studies are needed to look into whether the high costs are barriers to those new medications that can really make a difference for people living with neurologic disease,” Dr. Callaghan said.

The study was published online in Neurology.
 

Most expensive drugs

Using insurance claims data, the investigators compared the utilization and costs of new-to-market drugs from 2014 to 2018 with those for existing guideline-supported medications for treating 11 neurologic conditions.

The new drugs included:

• erenumab, fremanezumab, and galcanezumab for migraine.
• ocrelizumab and peginterferon beta-1a for multiple sclerosis (MS).
• pimavanserin and safinamide for Parkinson’s disease.
• droxidopa for orthostatic hypertension.
• eculizumab for myasthenia gravis (MG).
• edaravone for amyotrophic lateral sclerosis (ALS).
• deutetrabenazine and valbenazine for Huntington’s disease and tardive dyskinesia.
• patisiran and inotersen for transthyretin amyloidosis (ATTR).
• eteplirsen and deflazacort for Duchenne disease.

PHILADELPHIA – An international group of researchers has proposed the first classification criteria for chronic nonbacterial osteomyelitis (CNO) and a severe form of it, chronic recurrent multifocal osteomyelitis (CRMO).

CNO/CRMO most frequently affect children and adolescents and can significantly affect quality of life.

Yongdong (Dan) Zhao, MD, PhD, a pediatric rheumatologist at Seattle Children’s Hospital, Seattle, Washington, and Seza Ozen, MD, MSc, medical faculty head at Hacettepe University in Ankara, Turkey – members of the expert panel for criteria development – explained the proposed criteria, developed over 6 years, at the American College of Rheumatology 2022 Annual Meeting.

They gave examples of the point system that will help researchers correctly classify CNO/CRMO if the criteria are approved by ACR and the European Alliance of Associations for Rheumatology (EULAR).

Melissa S. Oliver, MD, a pediatric rheumatologist at Riley Children’s Hospital and Indiana University, Indianapolis, told this news organization: “This proposal is important because CNO/CRMO has primarily been a diagnosis of exclusion. There are no specific tests or biomarkers for this disease. It can mimic malignancy and infectious osteomyelitis in its presentation, and these must be ruled out thoroughly first.”

However, she noted, this can be challenging and can delay diagnosis and treatment.

The classification criteria are novel, she said, because an international collaborative group used a consensus process involving physicians managing CNO and patients or caregivers of children with CNO.
 

Findings for and against CNO

Dr. Ozen summarized some examples of findings for and against a CNO/CRMO classification.

Statistically significant findings in favor of CNO/CRMO, she said, include intermittent bone pain; bone pain in upper torso; swelling of upper torso; presence of symmetric lesions; and presence of adaptive immune cell and/or fibrosis in biopsy.

Conversely, findings against CNO/CRMO include fever; signs of infection by labs; signs of cancer by biopsy; specific abnormal x-ray/CT scan; specific abnormal MRI; or pain resolved with antibiotics alone.

Dr. Zhao described a point system with a threshold of 55 points for classification of CNO/CRMO.

He gave actual examples from the registry to demonstrate high and low probability of CNO/CRMO.
 

Pro-CNO example

The first was a boy, aged 7 years 10 months, who had a year and a half of pain in his back and legs, but no fever. Pain was constant, waxing and waning. He had a personal and family history of psoriasis and was tender to palpation at multiple sites. Labs were normal and bone biopsy and vitamin C tests were not done; imaging findings showed multiple bones were affected. There was no antibiotic treatment.

That patient was scored 81, much higher than the threshold of 55, and would be classified as having CNO.
 

Non-CNO example

Conversely, the following example of a patient would score 47 – under the threshold – and would not be classified as having CNO.

That patient was an 11-year-old boy who had 2 months of pain in his right thigh with no fever. The pain was constantly waxing and waning. He was tender to palpation at only his right thigh without swelling. Labs were normal. He had no coexisting conditions. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were not measured, and no vitamin C test was performed. Imaging showed one right femur lesion on a PET-CT scan. There was no antibiotic treatment, and a bone biopsy culture showed malignancy but no inflammation or fibrosis.

Dr. Zhao said the mimickers most likely to be misclassified are vitamin C deficiency; hypophosphatasia; benign bone tumor, such as osteogenic osteoma; and a malignancy with normal labs and multifocal pattern of bone lesions.

The classification criteria will be “extremely helpful to diagnose patients with CNO/CRMO earlier,” said Dr. Oliver, who helped develop the criteria.

“The goal is that the proposed classification criteria will be used by all physicians to diagnose suspected CNO patients earlier and refer to a rheumatologist earlier so that appropriate therapies will not be delayed.”

The group will seek ACR and EULAR endorsement, and if granted, work toward widespread implementation. The criteria will allow researchers to have a more homogeneous study population for future clinical trials, Dr. Zhao said.

Dr. Zhao, Dr. Ozen, and Dr. Oliver declared no relevant financial relationships. Dr. Oliver helped develop the proposed guidelines.

Boston dietitian Katarina Mollo, MEd, RDN, LDN, has virtually no memory of life without celiac disease (CD). Diagnosed at age 4, Dr. Mollo has been on a gluten-free diet for 41 years, which she says has kept her healthy and may also be why she hasn’t developed other autoimmune diseases. It’s also played a part in her thinking about screening patients with CD.

“I think [physicians] should definitely be screening people with celiac disease for autoimmune disorders, especially if they see things like anemia or if a child has dropped on the growth chart and has nutrient deficiencies,” said Dr. Mollo, whose daughter also has the disease. “I would recommend that they see someone who specializes in celiac disease so they can get monitored and have regular follow-up checks for nutrient deficiencies and other autoimmune disorders.”

Dr. Mollo’s views on screening are echoed by many CD specialists and physicians, who cite multiple studies that have found that people with the disease face higher risks for diabetes, thyroid conditions, arthritis, and other autoimmune disorders.

Gastroenterologist Alessio Fasano, MD, with Massachusetts General Hospital, Boston, said there has been a “shift in the paradigm in thinking” about cross-screening for CD and autoimmune disorders. As result, he believes the answer to the question of whether to routinely do so is a no-brainer.

“The bottom line is, if you have CD, it [should be] routine that during your annual follow-ups you check for the possibility of the onset of other autoimmune disease. And people with other autoimmune diseases, like type 1 diabetes, should also be screened for CD because of the comorbidity,” said Dr. Fasano, professor of pediatrics and gastroenterology at Harvard Medical School and professor of nutrition at the Harvard School of Public Health, both in Boston. “This is what we call good clinical practice.”
 

Screening, despite lack of consensus guidelines

Other CD specialists differ on the need for universal cross-screening but agree that, at least in some cases, people with one autoimmune disorder should be tested for others.

Jolanda Denham, MD, a pediatric gastroenterologist affiliated with Nemours Children’s Hospital in Orlando, routinely recommends that her patients with CD be screened for certain autoimmune disorders – such as type 1 diabetes and autoimmune thyroid and liver diseases – even though medical organizations have not developed clear consensus or standard guidelines on cross-screening.

“There currently is no evidence to support the screening of celiac patients for all autoimmune and rheumatologic disorders,” she said. “It is true that celiac disease is an autoimmune disorder, and as such, there is a definite increased risk of these disorders in patients with celiac disease and vice versa.”

Echoing Dr. Denham, New York–based gastroenterologist Benjamin Lebwohl, MD, president of the Society for the Study of Celiac Disease, urges physicians to look beyond consensus guidelines and to err on the side of caution and make the best decisions for their patients on a case-by-case basis.

“Given the increased risk of certain autoimmune conditions in people with celiac disease, it behooves physicians to have a low threshold to evaluate for these conditions if any suggestive symptoms are present,” said Dr. Lebwohl, director of clinical research at the Celiac Disease Center at Columbia University, New York.

“Whether to screen for these conditions among people who are entirely without symptoms is less certain, and there is no consensus on that. But it is reasonable and common to include some basic tests with annual blood work, such as thyroid function and a liver profile, since both autoimmune thyroid disease and autoimmune liver disease can be silent early on and the patient would potentially benefit from identification and treatment of these conditions,” he said.

The American Diabetes Association and the International Society of Pediatric and Adolescent Diabetes do recommend that people with diabetes be screened for CD years after diagnosis, noted Robert Rapaport, MD, a pediatric endocrinologist, with Kravis Children’s Hospital, New York. But in a study published in 2021, he and colleagues found that this wasn’t occurring, which prompted them to recommend yearly screening.

“There is a consensus that in children with type 1 diabetes, we screen them for other autoimmune disorders, specifically for thyroid disease and celiac disease,” said Dr. Rapaport, who is also Emma Elizabeth Sullivan Professor of Pediatric Endocrinology and Diabetes at Icahn School of Medicine at Mount Sinai, New York. “But there is no consensus going the other way – for patients with celiac disease, what other autoimmune conditions they should be screened for.”

This hasn’t kept some doctors from extending cross-screening efforts to their patients.

“At our center, we screen ... for thyroid disease and autoimmune liver disease as part of routine healthcare maintenance for our celiac disease patients. We discuss symptoms of diabetes and send screening with [hemoglobin] A1c for anyone who has symptoms,” said Lui Edwin, MD, a pediatric gastroenterologist with Children’s Hospital Colorado, Aurora, and director of the Colorado Center for Celiac Disease, who delivered a lecture on CD-autoimmune screening at the International Celiac Disease Symposium in October.

“It is definitely worth screening for celiac disease in [those with] other autoimmune disorders,” Dr. Edwin added.

“The symptoms can be very heterogeneous. Diagnosing and treating celiac disease can make a huge impact with respect to symptoms, quality of life, and preventing disease-related complications,” he said.
 

Mounting evidence linking CD to autoimmune disorders

Many studies have linked CD to a variety of other autoimmune disorders. The association could be due to common genetic factors or because CD might lead to such conditions. Researchers have found that people diagnosed with CD later in life are more likely to develop other autoimmune disorders.

Going gluten free has preventive advantages

In a landmark 2012 study, researchers with the Celiac Disease Center at Columbia University stopped short of recommending routine screening for the general public or asymptomatic individuals in high-prevalence groups. But they concluded that more screening of symptomatic individuals – and close relatives – would speed treatment for those with more than one autoimmune disorder.

They also noted that some studies have found that a gluten-free diet might help prevent the development of other autoimmune disorders.

Marisa Gallant Stahl, MD, a gastroenterologist with Children’s Hospital Colorado, agreed that it is important that physicians keep gluten-free diets in mind when determining which patients to cross-screen.

“The literature is mixed, but some studies suggest that treating celiac disease with a gluten-free diet actually augments the treatment and control of other autoimmune disorders [and] adherence to a gluten-free diet does reduce the risk of cancer associated with celiac disease,” she said.

Dr. Denham agreed. “Strict adherence to a gluten-free diet definitely protects against the development of enteropathy-associated T-cell lymphoma but may be protective against non-Hodgkin’s lymphoma and adenocarcinoma of the small intestine as well. All three are associated with long-term nonadherence to a gluten-free diet.”

She also noted that a gluten-free diet may help people with CD manage other autoimmune disorders, which can be complicated by CD.

“Good control of celiac disease will help prevent complications that can worsen symptoms and outcomes of concomitant autoimmune and rheumatologic disorders,” she said.
 

Other factors to consider

Dr. Fasano added that autoimmune disorders can be complicated by CD in cases in which oral medications or healthful foods are not properly absorbed in the intestines.

“For example, with Hashimoto’s disease, if you have hormone replacement with oral treatments and your intestines are not 100% functional because you have inflammation, then you may have a problem [with] the absorption of medications like levothyroxine,” he said.

“It’s the same story with diabetes. You don’t take insulin by mouth, but glucose [control] strongly depends on several factors, mostly what comes from the diet, and if it’s erratic, that can be a problem. ... So, the treatment of autoimmune diseases can be influenced by celiac disease,” he said.

In addition, Dr. Fasano and others believe that people with CD and other autoimmune disorders should be managed by a team of experts who can personalize the care on the basis of specific needs of the individual patient. These should include specialists, dietitians, mental health counselors, and family social workers.

“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

Many studies have linked CD to a variety of other autoimmune disorders. The association could be due to common genetic factors or because CD might lead to such conditions. Researchers have found that people diagnosed with CD later in life are more likely to develop other autoimmune disorders.

Going gluten free has preventive advantages

In a landmark 2012 study, researchers with the Celiac Disease Center at Columbia University stopped short of recommending routine screening for the general public or asymptomatic individuals in high-prevalence groups. But they concluded that more screening of symptomatic individuals – and close relatives – would speed treatment for those with more than one autoimmune disorder.

They also noted that some studies have found that a gluten-free diet might help prevent the development of other autoimmune disorders.

Marisa Gallant Stahl, MD, a gastroenterologist with Children’s Hospital Colorado, agreed that it is important that physicians keep gluten-free diets in mind when determining which patients to cross-screen.

“The literature is mixed, but some studies suggest that treating celiac disease with a gluten-free diet actually augments the treatment and control of other autoimmune disorders [and] adherence to a gluten-free diet does reduce the risk of cancer associated with celiac disease,” she said.

Dr. Denham agreed. “Strict adherence to a gluten-free diet definitely protects against the development of enteropathy-associated T-cell lymphoma but may be protective against non-Hodgkin’s lymphoma and adenocarcinoma of the small intestine as well. All three are associated with long-term nonadherence to a gluten-free diet.”

She also noted that a gluten-free diet may help people with CD manage other autoimmune disorders, which can be complicated by CD.

“Good control of celiac disease will help prevent complications that can worsen symptoms and outcomes of concomitant autoimmune and rheumatologic disorders,” she said.
 

Other factors to consider

Dr. Fasano added that autoimmune disorders can be complicated by CD in cases in which oral medications or healthful foods are not properly absorbed in the intestines.

“For example, with Hashimoto’s disease, if you have hormone replacement with oral treatments and your intestines are not 100% functional because you have inflammation, then you may have a problem [with] the absorption of medications like levothyroxine,” he said.

“It’s the same story with diabetes. You don’t take insulin by mouth, but glucose [control] strongly depends on several factors, mostly what comes from the diet, and if it’s erratic, that can be a problem. ... So, the treatment of autoimmune diseases can be influenced by celiac disease,” he said.

In addition, Dr. Fasano and others believe that people with CD and other autoimmune disorders should be managed by a team of experts who can personalize the care on the basis of specific needs of the individual patient. These should include specialists, dietitians, mental health counselors, and family social workers.

“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

Boston dietitian Katarina Mollo, MEd, RDN, LDN, has virtually no memory of life without celiac disease (CD). Diagnosed at age 4, Dr. Mollo has been on a gluten-free diet for 41 years, which she says has kept her healthy and may also be why she hasn’t developed other autoimmune diseases. It’s also played a part in her thinking about screening patients with CD.

“I think [physicians] should definitely be screening people with celiac disease for autoimmune disorders, especially if they see things like anemia or if a child has dropped on the growth chart and has nutrient deficiencies,” said Dr. Mollo, whose daughter also has the disease. “I would recommend that they see someone who specializes in celiac disease so they can get monitored and have regular follow-up checks for nutrient deficiencies and other autoimmune disorders.”

Dr. Mollo’s views on screening are echoed by many CD specialists and physicians, who cite multiple studies that have found that people with the disease face higher risks for diabetes, thyroid conditions, arthritis, and other autoimmune disorders.

Gastroenterologist Alessio Fasano, MD, with Massachusetts General Hospital, Boston, said there has been a “shift in the paradigm in thinking” about cross-screening for CD and autoimmune disorders. As result, he believes the answer to the question of whether to routinely do so is a no-brainer.

“The bottom line is, if you have CD, it [should be] routine that during your annual follow-ups you check for the possibility of the onset of other autoimmune disease. And people with other autoimmune diseases, like type 1 diabetes, should also be screened for CD because of the comorbidity,” said Dr. Fasano, professor of pediatrics and gastroenterology at Harvard Medical School and professor of nutrition at the Harvard School of Public Health, both in Boston. “This is what we call good clinical practice.”
 

Screening, despite lack of consensus guidelines

Other CD specialists differ on the need for universal cross-screening but agree that, at least in some cases, people with one autoimmune disorder should be tested for others.

Jolanda Denham, MD, a pediatric gastroenterologist affiliated with Nemours Children’s Hospital in Orlando, routinely recommends that her patients with CD be screened for certain autoimmune disorders – such as type 1 diabetes and autoimmune thyroid and liver diseases – even though medical organizations have not developed clear consensus or standard guidelines on cross-screening.

“There currently is no evidence to support the screening of celiac patients for all autoimmune and rheumatologic disorders,” she said. “It is true that celiac disease is an autoimmune disorder, and as such, there is a definite increased risk of these disorders in patients with celiac disease and vice versa.”

Echoing Dr. Denham, New York–based gastroenterologist Benjamin Lebwohl, MD, president of the Society for the Study of Celiac Disease, urges physicians to look beyond consensus guidelines and to err on the side of caution and make the best decisions for their patients on a case-by-case basis.

“Given the increased risk of certain autoimmune conditions in people with celiac disease, it behooves physicians to have a low threshold to evaluate for these conditions if any suggestive symptoms are present,” said Dr. Lebwohl, director of clinical research at the Celiac Disease Center at Columbia University, New York.

“Whether to screen for these conditions among people who are entirely without symptoms is less certain, and there is no consensus on that. But it is reasonable and common to include some basic tests with annual blood work, such as thyroid function and a liver profile, since both autoimmune thyroid disease and autoimmune liver disease can be silent early on and the patient would potentially benefit from identification and treatment of these conditions,” he said.

The American Diabetes Association and the International Society of Pediatric and Adolescent Diabetes do recommend that people with diabetes be screened for CD years after diagnosis, noted Robert Rapaport, MD, a pediatric endocrinologist, with Kravis Children’s Hospital, New York. But in a study published in 2021, he and colleagues found that this wasn’t occurring, which prompted them to recommend yearly screening.

“There is a consensus that in children with type 1 diabetes, we screen them for other autoimmune disorders, specifically for thyroid disease and celiac disease,” said Dr. Rapaport, who is also Emma Elizabeth Sullivan Professor of Pediatric Endocrinology and Diabetes at Icahn School of Medicine at Mount Sinai, New York. “But there is no consensus going the other way – for patients with celiac disease, what other autoimmune conditions they should be screened for.”

This hasn’t kept some doctors from extending cross-screening efforts to their patients.

“At our center, we screen ... for thyroid disease and autoimmune liver disease as part of routine healthcare maintenance for our celiac disease patients. We discuss symptoms of diabetes and send screening with [hemoglobin] A1c for anyone who has symptoms,” said Lui Edwin, MD, a pediatric gastroenterologist with Children’s Hospital Colorado, Aurora, and director of the Colorado Center for Celiac Disease, who delivered a lecture on CD-autoimmune screening at the International Celiac Disease Symposium in October.

“It is definitely worth screening for celiac disease in [those with] other autoimmune disorders,” Dr. Edwin added.

“The symptoms can be very heterogeneous. Diagnosing and treating celiac disease can make a huge impact with respect to symptoms, quality of life, and preventing disease-related complications,” he said.

THE CASE

A 34-year-old man was referred to the sports medicine clinic for evaluation of lumbar radiculopathy. He had a 2-year history of chronic lower back pain that started while he was working on power line towers in Puerto Rico. The back pain was achy, burning, shooting, and stabbing in nature. He had been treated with anti-inflammatories by a company health care provider while in Puerto Rico, but he did not have any imaging done.

At that time, he had tingling and burning that radiated down his left leg to his ankle. The patient also had leg spasms—in his left leg more than his right—and needed a cane when walking. His symptoms did not worsen at any particular time of day or with activity. He had no history of eating exotic foods or sustaining any venomous bites/stings. Ultimately, the back pain and leg spasms forced him to leave his job and return home to Louisiana.

Upon presentation to the sports medicine clinic, he explained that things had worsened since his return home. The pain and burning in his left leg had increased and were now present in his right leg, as well (bilateral paresthesias). In addition, he said he was feeling anxious (and described symptoms of forgetfulness, confusion, and agitation), was sleeping less, and was experiencing worsening fatigue.

Work-ups over the course of the previous 2 years had shed little light on the cause of his symptoms. X-rays of his lumbar spine revealed moderate degenerative changes at L5-S1. A lab work-up was negative and included a complete blood count, testing for HIV and herpes, a hepatitis panel, an antinuclear antibody screen, a C-reactive protein test, and a comprehensive metabolic panel. Thyroid-stimulating hormone, creatine kinase, rapid plasma reagin, and human leukocyte antigen B27 tests were also normal.

Magnetic resonance imaging (MRI) revealed a cystic lesion in the right ilium near the sacroiliac joint. A more recent follow-up MRI and computed tomography scan of the pelvis found the cyst to be stable and well marginalized, with no cortical erosion. Attempts at physical therapy had been unsuccessful because of the pain and decreasing muscle strength in his lower extremities. The patient’s primary care provider was treating him with meloxicam 15 mg/d and duloxetine 60 mg/d, but that had not provided any relief.

Our physical examination revealed a patient who was in mild distress and had limited lumbar spine range of motion (secondary to pain in all planes) and significant paraspinal spasms on the right side in both the lumbar and thoracic regions. The patient had reduced vibratory sensation on his left side vs the right, with a 256-Hz tuning fork at the great toe, as well as reduced sensation to fine touch with a cotton swab and a positive Babinski sign bilaterally. Lower extremity reflexes were hyperreflexic on the left compared with the right. He had no pronator drift; Trendelenburg, straight leg raise, Hoover sign, and slump tests were all negative. His gait was antalgic with a cane, as he described bilateral paresthesias.

THE DIAGNOSIS

The differential diagnosis for low back pain is quite extensive and includes simple mechanical low back pain, lumbar radiculopathy, facet arthritis, spinal stenosis, spondylolysis/spondylolisthesis, and referred pain from the hip, knee, or upper back. It can also be caused by referred pain from visceral organs such as the liver, colon, or kidneys. Low back pain can also signal primary or metastatic disease. However, most of these potential diagnoses had been ruled out with imaging and lab tests.

Continue to: Two things caught our attention

Two things caught our attention. First: Mechanical low back pain and the associated discogenic radiculopathy would be unilateral, manifesting with asymmetric paresthesias and pain. Our patient had weakness in gait and pain and burning in both of his legs. Second: Our patient described decreased sleep and feeling anxious, with symptoms of forgetfulness, confusion, and agitation. These factors prompted us to look beyond the normal differential and consider a potential toxicity. A heavy metal screen was ordered, and the results were positive for arsenic toxicity.

DISCUSSION

Arsenic toxicity is a global health problem that affects millions of people.^1,2 Arsenic has been used for centuries in depilatories, cosmetics, poisons, and therapeutic agents. Today it is used as a treatment for leukemia and in several ayurvedic and homeopathic remedies.^3-7 It is a common earth element found in ground water and a waste product from mining and the manufacturing of glass, computer chips, wood preservatives, and various pesticides.^2,3,7,8

A great masquerader. Once in the body, arsenic can cause many serious ailments ranging from urinary tract, liver, and skin cancers to various peripheral and central nervous system disorders.² Arsenic can cause symmetrical peripheral neuropathy characterized by sensory nerves being more sensitive than motor nerves.^2,3,5,6 Clinically, it causes numbness and paresthesias of the distal extremities, with the lower extremities more severely affected.^3,6 Symptoms can develop within 2 hours to 2 years of exposure, with vomiting, diarrhea, or both preceding the onset of the neuropathy.^2,3,5,6 Arsenic is linked to forgetfulness, confusion, visual distortion, sleep disturbances, decreased concentration, disorientation, severe agitation, paranoid ideation, emotional lability, and decreases in locomotor activity.^3,5,6

Testing and treatment. Arsenic levels in the body are measured by blood and urine testing. Blood arsenic levels are typically detectable immediately after exposure and with continued exposure, but quickly normalize as the metal integrates into the nonvascular tissues. Urine arsenic levels can be detected for weeks. Normal levels for arsenic in both urine and blood are ≤ 12 µg/L.³ Anything greater than 12 µg/L is considered high; critically high values are those above 50 µg/L.^3,5 Our patient’s blood arsenic level was 13 µg/L.

Several of the patient’s symptoms prompted us to look beyond the normal differential and consider a potential toxicity.

Treatment involves removing the source of the arsenic. Chelation therapy should be pursued when urine arsenic levels are greater than 50 µg/L or when removing the source of the arsenic fails to reduce arsenic levels. Chelation therapy should be continued until urine arsenic levels are below 20 µg/L.^5,6

Continue to: After discussing potential sources of exposure

After discussing potential sources of exposure, our patient decided to move out of the house he shared with his ex-wife. He started to recover soon after moving out. Two weeks after his clinic visit, he no longer needed a cane to walk, and his blood arsenic level had dropped to 6 µg/L. Two months after his clinic visit, the patient’s blood arsenic level was undetectable. The patient’s peripheral neuropathy symptoms continued to improve.

The source of this patient’s arsenic exposure was never confirmed. The exposure could have occurred in Puerto Rico or in Louisiana. Even though no one else in the Louisiana home became ill, the patient was instructed to contact the local health department and water department to have the water tested. However, when he returned to the clinic for follow-up, he had not followed through.

THE TAKEAWAY

When evaluating causes of peripheral neuropathy, consider the possibility of heavy metal toxicity, which can be easily overlooked by the busy clinician. In this case, the patient initially experienced asymmetric paresthesia that gradually increased to burning pain and weakness, with reduced motor control bilaterally. This was significant because mechanical low back pain and the associated discogenic radiculopathy would be unilateral, manifesting with asymmetric paresthesias and pain.

Our patient’s leg symptoms, the constellation of forgetfulness, confusion, and agitation, and his sleep issues prompted us to look outside our normal differential. Fortunately, once arsenic exposure ceases, patients will gradually improve because arsenic is rapidly cleared from the bloodstream.^3,6

PHILADELPHIA – Combining the immunomodulatory agent mycophenolate with the antifibrotic pirfenidone led to more rapid improvement and showed a trend to be more effective than mycophenolate mofetil alone for treating the signs and symptoms of scleroderma-related interstitial lung disease, but the combination therapy came with an increase in side effects, according to results from the Scleroderma Lung Study III.

Dinesh Khanna, MBBS, MSc, of the University of Michigan, Ann Arbor, presented the results at the annual meeting of the American College of Rheumatology. He noted some problems with the study – namely its small size, enrolling only 51 patients, about one-third of its original goal. But he also said it showed a potential signal for efficacy and that the study itself could serve as a “template” for future studies of combination mycophenolate mofetil (MMF) plus pirfenidone therapy for scleroderma-related interstitial lung disease (SSc-ILD).

“The pirfenidone patients had quite a bit more GI side effects and photosensitivity, and those are known side effects,” Dr. Khanna said in an interview. “So the combination therapy had more side effects but trends to higher efficacy.”

The design of SLS-III, a phase 2 clinical trial, was a challenge, Dr. Khanna explained. The goal was to enroll 150 SSc-ILD patients who hadn’t had any previous treatment for their disease. Finding those patients proved difficult. “In fact, if you look at the recent history, 70% of the patients with early diffuse scleroderma are on MMF,” he said in his presentation. Compounding low study enrollment was the intervening COVID-19 pandemic, he added.
 

Testing a faster-acting combination

Nonetheless, the trial managed to enroll 27 patients in the combination therapy group and 24 in the MMF-plus-placebo group and compared their outcomes over 18 months. Study dosing was 1,500 mg MMF twice daily and pirfenidone 801 mg three times daily, titrated to the tolerable dose.

Despite the study’s being underpowered, Dr. Khanna said, it still reported some notable outcomes that merit further investigation. “I think what was intriguing in the study was the long-term benefit in the patient-reported outcomes and the structural changes,” he said in the interview.

Among those notable outcomes was a clinically significant change in forced vital capacity (FVC) percentage for the combination vs. the placebo groups: 2.24% vs. 2.09%. He also noted that the combination group saw a somewhat more robust improvement in FVC at six months: 2.59% (± 0.98%) vs. 0.92% (± 1.1%) in the placebo group.

The combination group showed greater improvements in high-resolution computed tomography-evaluated lung involvement and lung fibrosis and patient-reported outcomes, including a statistically significant 3.67-point greater improvement in PROMIS-29 physical function score (4.42 vs. 0.75).

The patients on combination therapy had higher rates of serious adverse events (SAEs), and seven discontinued one or both study drugs early, all in the combined arm. Four combination therapy patients had six SAEs, compared to two placebo patients with three SAEs. In the combination group, SAEs included chest pain, herpes zoster ophthalmicus, nodular basal cell cancer, marginal zone B cell lymphoma, renal crisis, and dyspnea. SAEs in the placebo group were colitis, COVID-19 and hypoxic respiratory failure.

Study design challenges

Nonetheless, Dr. Khanna said the SLS-III data are consistent with the SLS-II findings, with mean improvements in FVC of 2.24% and 2.1%, respectively.

“The next study may be able to replicate what we tried to do, keeping in mind that there are really no MMF-naive patients who are walking around,” Dr. Khanna said. “So the challenge is about the feasibility of recruiting within a trial vs. trying to show a statistical difference between the drug and placebo.”

This study could serve as a foundation for future studies of MMF in patients with SSc-ILD, Robert Spiera, MD, of the Hospital for Special Surgery in New York, said in an interview. “There are lessons to be learned both from the study but also from prior studies looking at MMF use in the background in patients treated with other drugs in clinical trials,” he said.

Dr. Spiera noted that the study had other challenges besides the difficulty in recruiting patients who hadn’t been on MMF therapy. “A great challenge is that the benefit with regard to the impact on the lungs from MMF seems most prominent in the first 6 months to a year to even 2 years that somebody is on the drug,” he said.

The other challenge with this study is that a large proportion of patients had limited systemic disease and relatively lower levels of skin disease compared with other studies of patients on MMF, Dr. Spiera said.

“The optimal treatment of scleroderma-associated lung disease remains a very important and not-adequately met need,” he said. “Particularly, we’re looking for drugs that are tolerable in a patient population that are very prone to GI side effects in general. This study and others have taught us a lot about trial design, and I think more globally this will allow us to move this field forward.”

Dr. Khanna disclosed relationships with Actelion, Boehringer Ingelheim, Bristol-Myers Squibb, CSL Behring, Horizon Therapeutics USA, Janssen Global Services, Prometheus Biosciences, Mitsubishi Tanabe Pharma Corp., Genentech/Roche, Theraly, and Pfizer. Genentech provided funding for the study and pirfenidone and placebo drugs at no cost.

PHILADELPHIA – Aggressive therapy using conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in combination with biologic agents early, soon after a child is diagnosed with polyarticular juvenile idiopathic arthritis (pJIA), enabled more patients to achieve clinical remission and longer times in inactive disease than more conventional therapeutic approaches, 3-year results of prospective, observational study demonstrated.

The results of The Childhood Arthritis and Rheumatology Research Alliance STOP-JIA study, which Yukiko Kimura, MD, presented at the annual meeting of the American College of Rheumatology, showed early combination therapy had benefits, compared with other treatment strategies that were more evident at 3 years than at 1 year of study.

“The STOP-JIA study showed that, after 3 years, patients who started a biologic early on in combination with methotrexate spent more time in inactive disease and achieved clinical remission more often when compared to those started on traditional step-up therapy,” Dr. Kimura, chief of pediatric rheumatology at Hackensack (N.J.) Meridian Health and professor of pediatrics at the Hackensack Meridian School of Medicine, said at a press conference. “This study shows that the treatment of poly-JIA patients receive initially very early on in their disease matters even 3 years after that treatment was started.”

The study compared three CARRA consensus treatment plans (CTP) for untreated pediatric pJIA patients: step-up (SU) – starting conventional synthetic DMARD therapy and adding a biologic if needed after 3 or more months; early-combination (EC) therapy – starting synthetic and biologic DMARDs together; and biologic first (BF) therapy – starting biologic DMARD monotherapy.

Dr. Kimura explained the rationale for the study. “Since biologic treatments were introduced more than 20 years ago, the prognosis for JIA significantly improved. These very effective medicines often work wonders, quickly reducing pain and inflammation in joint disease activity,” she said in the press conference. “What is not known, however, is when is the best time to start these very effective treatments.”

The most common approach is to start with a synthetic DMARD, typically methotrexate, and wait before starting a biologic, Dr. Kimura said.

“But even though methotrexate can work very well by itself, it does not work for every patient, and we don’t know whether waiting months for it to work and then starting a biologic might potentially lessen their effectiveness,” Dr. Kimura added. “We don’t know if there’s a window of opportunity that’s lost while waiting to see whether methotrexate will work.”

The study originally enrolled 400 patients, 297 of whom completed the 3-year visit – 190 in SU, 76 in EC and 31 in BF. At 12 months, the study found no statistically significant difference in clinically inactive disease (CID) between the groups, Dr. Kimura said.

Even at the 3-year visit, the percentage of patients in CID off glucocorticoids and clinical Juvenile Arthritis Disease Activity Score based on 10 joints inactive disease (cJADAS 10 ID) did not differ among the three groups, Dr. Kimura said in presenting the results. “But,” she added, “greater proportions of early-combination CTP group were able to achieve clinical remissions and spend more time with inactive disease in both CID and cJADAS 10.”

A closer look at the outcomes showed some separation between early-combination therapy and the other two treatment plans. The incidence of clinical remission (at any time point over 36 months) was 67.1% in the EC group vs. 49.1% and 47.3%, respectively, in the BF and SU groups, Dr. Kimura said. “The difference between the early-combination and step-up groups was highly significant [P = .007],” she added.

EC also had an edge in the percentage of time patients spent in CID (over 36 months): 39.2% versus 32% and 27.4%, respectively, in the BF and SU groups (P = .006 for EV vs. SU), as well as cJADAS 10 ID (50.6% in EC group vs. 42.8% and 37.5%, respectively in the BF and SU groups; P = .005 for EC vs. SU).

Dr. Kimura said that the STOP JIA trial will continue with longer-term analysis and ongoing monitoring of study patients through the CARRA registry. “These longer-term analyses and readouts will be important because even though the results at 12 months didn’t seem as definitive, it seems the longer we go, the more impact we see of the treatments that were started early on in this disease.”

The findings from this study are “significantly important,” Nina T. Washington, MD, MPH, a pediatric rheumatologist at the University of New Mexico Hospital, Albuquerque, and the Mary Bridge Children’s Hospital in Tacoma, Wash., said in an interview. “At least for the past decade we’ve really been advocating towards earlier and aggressive therapy, and that’s what this study shows: the sooner you can treat this disease, the sooner you can attack those joints that are inflamed, the better outcome you give the patient.”

The study also confirms that pediatric rheumatologists are not overtreating patients with pJIA, she added.

“In a sense we’re actually treating and preventing and if you have a child that has arthritis, it’s okay to treat that child,” Dr. Washington said. “For me that’s the most reassuring thing: that I’m not necessarily going overboard. If I have a child with polyarticular JIA and they have multiple inflamed joints and I have the evidence as they’re sitting in front of me, and I treat them. I’m going to give them the best outcome.”

The Patient Centered Outcomes Research Institute provided study funding. Dr. Kimura is chair of the CARRA JIA disease research committee and cochair of the CARRA Registry and Research Oversight Committee. She disclosed a financial relationship with Genentech. Dr. Washington has no relevant relationships to disclose.

Researchers have found a link between age of diagnosis and various clinical characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV).

The findings, presented at the annual meeting of the American College of Rheumatology, may have implications for research and treatment, especially in children.

AAV is a group of conditions characterized by the development of autoantibodies to the neutrophil proteins proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA).

The rare autoimmune condition can cause systemic inflammation and damage, sometimes permanent, to small- and medium-sized arteries. Clinical presentations vary and can include several organs, including skin, stomach, intestines, lung, and kidney, as well as airways in ear, nose, and throat.
 

Data limited on child vs. adult characteristics

AAV can be diagnosed in any decade of life, but clinical characteristics and outcomes often differ between children and adults, and data are limited. Studies often exclude children.

Lead author Jessica Bloom, MD, MSCS, a pediatric rheumatologist and assistant professor of pediatrics at Children’s Hospital Colorado, Aurora, and colleagues performed an analysis of patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) who were enrolled in the Vasculitis Clinical Research Consortium Longitudinal Studies from 2013 to 2021.

Patients with eosinophilic GPA (EGPA) were analyzed separately. Children and young adults with EGPA were combined because of the small sample size (n = 87).

The groups were sorted by the age they were diagnosed: under 18 years old, 18-40, 40-65, and older than 65.
 

More than 1,000 patients included

Dr. Bloom’s team analyzed data from 1,020 patients: 61 diagnosed as children, 240 as young adults, 560 as middle-aged adults, and 159 diagnosed as older adults. At all ages, about nine out of 10 patients were White.

They found 852 (84%) had GPA and 165 (16%) had MPA. The analysis also showed 893 (92%) of patients with ANCA results were ANCA positive: 637 (65%) with PR3-ANCA, 247 (25%) with MPO-ANCA, and 9 (1%) with both.

Differences between age groups included:

• Children experienced more subglottic stenosis and alveolar hemorrhage than adults with the condition.
• About half of patients diagnosed in childhood received both cyclophosphamide and rituximab. That rate decreased with increasing age of diagnosis to as low as 14% for those diagnosed in older adulthood. 
• More females than males in all age groups were diagnosed with AAV, but the difference was most pronounced when diagnosed in childhood, and female predominance declined as age increased.
• Older adults experienced more neurologic disease and less musculoskeletal and sinus involvement.

Additionally, for those diagnosed after age 65, after adjusting for disease length and whether they were taking cyclophosphamide and/or rituximab, the Vasculitis Damage Index (VDI) and ANCA Vasculitis Index of Damage (AVID) scores were higher than for those diagnosed in childhood.

“However, these differences are no longer significant when medication toxicity and comorbidity-related items are excluded. Thus, differences in the VDI and AVID scores are driven by non–disease-specific damage,” Dr. Bloom said.
 

Bringing children into the clinical discussion

Dr. Bloom said in an interview that many pediatric rheumatologists believe kids with vasculitis are like small adults and should be treated similarly, but she said the picture may be more complex than that.

For example, the findings that children have more subglottic stenosis and alveolar hemorrhage than adults “may warrant more aggressive therapy,” she said. Children also have different growth and psychosocial risk factors during their disease course and may live longer with the disease than those in older age groups.

“Our study helps to point out these differences and bring children into the discussion,” Dr. Bloom said. “It also recognizes that damage scores used in studies and care may not adequately assess disease across the lifespan, as they are largely influenced by items not specific to the disease but rather medication toxicity and comorbidities, such as osteoporosis, cataracts, and malignancy.”

Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at Hospital for Special Surgery, New York, said in an interview that the work highlights interesting information about the fact that disease features are skewed differently in children – “in particular the higher likelihood of upper airway [subglottic] disease, and potentially severe lower airway disease [alveolar hemorrhage].”

However, from a practical standpoint, Dr. Spiera said, “I am not sure that this will change our clinical approach to different patients, but the differences in disease features and even the sex differences in terms of who are afflicted with GPA [more often children and more likely to be female] may offer insights into disease pathogenesis.”

Dr. Bloom received funding from the Vasculitis Clinical Research Consortium and Vasculitis Foundation to conduct this work as a VCRC-VF fellow. Several coauthors reported various conflicts of interest with pharmaceutical companies. Dr. Spiera declared no relevant financial relationships.
