Financial Hardship Common With Rheumatologic Disease: How Can Doctors Help?

Many patients struggle with healthcare costs and basic expenses, according to new research.

People with rheumatologic diseases often experience a hidden symptom: financial toxicity or significant economic strain from out-of-pocket costs. A new study of 41,502 patients published in JCR: Journal of Clinical Rheumatology showed that 20% of those with rheumatologic diseases faced financial hardship from medical expenses, with 55% of those unable to pay their bills. 

Compared with patients who do not have rheumatologic diseases, and after clinical and sociodemographic factors were controlled for, patients with rheumatologic diseases were:

  • 29% more likely to have high levels of financial hardship — difficulty paying; needing to pay over time; or inability to pay bills for doctors, dentists, hospitals, therapists, medication, equipment, nursing homes, or home care.
  • 53% more likely to have high levels of financial distress — significant worry about having enough money for retirement, paying medical costs in the event of a serious illness or accident, maintaining their standard of living, paying their usual healthcare costs, and affording their normal monthly bills and housing costs.
  • 29% more likely to experience food insecurity, defined as limited or uncertain access to adequate food.
  • 58% more likely to report cost-related medication nonadherence — skipping doses, taking less medication, or delaying filling a prescription to save money.

People who were younger than 64 years, male, Black, or uninsured had higher odds of experiencing financial hardship, financial distress, food insecurity, and cost-related medication nonadherence. 

This study highlights “just how costly everyday rheumatologic conditions can be for your average American,” said lead study author Troy Amen, MD, MBA, an orthopedic surgery resident at the Hospital for Special Surgery in New York City. These diseases can be disabling, limiting a patient’s ability to work at the very time when expensive medications are needed. 

“It’s critical for clinicians to recognize how common the financial burden from healthcare costs can be, and only then can they take steps to better support patients,” said G. Caleb Alexander, MD, MS, professor of epidemiology at Johns Hopkins University in Baltimore, who was not involved in the study. 

Here’s how healthcare providers can help. 

Consider skipped medication a red flag. It’s often the first sign of a financial concern. “Sometimes with these problems, it looks like simple medication noncompliance, but it’s really a more complex form of nonadherence,” said Susan M. Goodman, MD, professor of clinical medicine at Weill Cornell Medicine in New York City and a coauthor of the study. “And I think if someone’s not taking the medication that had been very helpful, it does behoove the physician to try and figure out why that is.”

Normalize the issue to help patients open up. “I will often say, ‘You know, many, many patients don’t take their medicines exactly as prescribed. About how many days a week do you take this medicine?’” said Dr. Alexander. “If you ask in a nonconfrontational, supportive manner, I’ve found that patients are quite candid.” 

Don’t assume insurance has it covered. If patients are uninsured, help them enroll in (or renew) insurance coverage. But don’t assume insurance will solve the whole problem. “There are many people who, although they do have coverage, still can’t afford their medications,” said Dr. Goodman.

For products on high formulary tiers, the patient’s monthly cost can be hundreds to thousands of dollars. “Over the past 10-20 years, we’ve seen remarkable technological innovation in the types of medicines being brought to market, and here, I’m referring primarily to biologics and medicines made from living cells,” said Dr. Alexander, “but many of these have a price tag that is simply astronomical, and insurers aren’t going to bear the brunt of these costs alone.” 

Biosimilars can be a bit more affordable, but “the dirty little secret of biosimilars is that they’re not really very much less expensive,” said Dr. Goodman. “If your patient is doing well on a drug that gets dropped from their insurance plan’s formulary, or if they switch to a plan that doesn’t cover it, try calling and advocating for an exception. It’s an uphill battle, but it sometimes works,” she said.

If not? Help your patients apply for a patient assistance program. Many drug manufacturers offer copay assistance through their websites, and nonprofit patient assistance organizations such as the PAN Foundation, the Patient Advocate Foundation’s Co-Pay Relief Program, or The Assistance Fund can also help fill the gaps. One study published in the Journal of Managed Care and Specialty Pharmacy showed that in patients with rheumatoid arthritis, copay assistance was associated with 79% lower odds of prescription abandonment (failure to fill within 30 days of health plan approval).

Beware of “shiny penny syndrome.” It’s easy to get excited about new, innovative medications, especially when sales reps provide plenty of free samples. “There is a tendency to treat every new medicine as if it’s a bright shiny object in the streambed, and you know that’s not always the case,” said Dr. Alexander. “So, I think we have to be careful, especially in settings when we’re talking about ultra–high-cost medicines, that we’re aware of the burden these medicines may place on patients and that we’re navigating that with patients together, and not simply leaving that as a conversation that never happens in the exam room.”

Maybe there’s an older, time-tested drug that works just as well as the newer, more expensive one. Perhaps there is a slightly less effective medicine that costs a lot less. “These are cost–quality trade-offs that clinicians and patients should be navigating together,” said Dr. Alexander. For example, in a patient with rheumatoid arthritis, a tumor necrosis factor alpha inhibitor might work similarly to or almost as well as an interleukin inhibitor, the newer and typically more expensive choice. 

“Some clinicians may find it quite unpalatable to be potentially compromising on safety or efficacy in the interest of reducing the cost of therapies, but as former Surgeon General C. Everett Koop said, ‘Drugs don’t work in patients who don’t take them,’ ” said Dr. Alexander. “So, if the choice is for someone not to be taking a treatment, or to be taking one that may be a little bit less good, I’ll take the latter.”

Consider the patient’s broader care team. Encourage patients to discuss costs with their other healthcare providers. For patients taking multiple medications, a few adjustments could make a big impact on their wallets. Primary care providers or other specialists might recommend some older and less expensive, but still effective, drugs, such as thiazides for hypertension or metformin for type 2 diabetes. Another option might be to simplify the patient’s regimen or include some fixed-dose combination pills in place of two others.

And if no one has referred the patient to a medical social worker, make the connection. A social worker can put patients in touch with local agencies that can help them with food, housing, and other nonmedical costs. 

Talk about this problem with anyone who will listen. One of the best ways to help patients with rheumatologic diseases is to ensure that decision-makers don’t overlook them. Professional societies such as the American College of Rheumatology can be great resources for advocacy in Washington, DC. Political movements can make drugs more affordable — for example, insulin prices have dropped in recent years because of political pressure, said Dr. Goodman.

“A lot of our national policy now focuses on aiding patients with single high-cost events, but we hope studies like these can really get policymakers to think through how to better support patients with chronic conditions that may have been historically ignored, such as patients with rheumatologic disease,” said Dr. Amen. 

The first step is raising awareness and telling your story. “As providers, we are often [at the] forefront in witnessing how chronic conditions and their associated costs can negatively affect patients’ lives and even alter clinical outcomes,” Dr. Amen added. “By publishing data and sharing meaningful patient stories and clinical vignettes, we can begin to advocate and humanize these patients to policymakers.”

Meet the Pregnancy Challenges of Women With Chronic Conditions

Article Type

Tue, 07/16/2024 - 12:44

Preconception and prenatal care are more complicated in women with chronic health conditions but attention to disease management and promoting the adoption of a healthier lifestyle can improve outcomes for mothers and infants, according to a growing body of research.

The latest version of the International Federation of Gynecology and Obstetrics Preconception Checklist, published in the International Journal of Gynecology & Obstetrics, highlights preexisting chronic medical conditions such as diabetes, lupus, and obesity as key factors to address in preconception care through disease management. A growing number of studies support the impact of these strategies on short- and long-term outcomes for mothers and babies, according to the authors.
 

Meet Glycemic Control Goals Prior to Pregnancy

“Women with diabetes can have healthy pregnancies but need to prepare for pregnancy in advance,” Ellen W. Seely, MD, professor of medicine at Harvard Medical School and director of clinical research in the endocrinology, diabetes, and hypertension division of Brigham and Women’s Hospital, Boston, said in an interview.

“If glucose levels are running high in the first trimester, this is associated with an increased risk of birth defects, some of which are very serious,” said Dr. Seely. Getting glucose levels under control reduces the risk of birth defects in women with diabetes close to that of the general population, she said.

The American Diabetes Association has set a goal for women to attain an HbA1c of less than 6.5% before conception, Dr. Seely said. “In addition, some women with diabetes may be on medications that should be changed to another class prior to pregnancy,” she noted. Women with type 1 or type 2 diabetes often have hypertension as well, but ACE inhibitors are associated with an increased risk of fetal renal damage that can result in neonatal death; therefore, these medications should be stopped prior to pregnancy, Dr. Seely emphasized.

“If a woman with type 2 diabetes is on medications other than insulin, recommendations from the ADA are to change to insulin prior to pregnancy, since we have the most data on the safety profile of insulin use in pregnancy,” she said.

To help women with diabetes improve glycemic control prior to pregnancy, Dr. Seely recommends home glucose monitoring, with checks of glucose four times a day, fasting, and 2 hours after each meal, and adjustment of insulin accordingly.

A healthy diet and physical activity remain important components of glycemic control as well. A barrier to proper preconception and prenatal care for women with diabetes is not knowing that a pregnancy should be planned, Dr. Seely said. Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Although studies of drugs have been done to inform preconception care for women with diabetes, research is lacking in several areas, notably the safety of GLP-1 agonists in pregnancy, said Dr. Seely. “This class of drug is commonly used in type 2 diabetes and the current recommendation is to stop these agents 2 months prior to conception,” she said.
 

 

 

Conceive in Times of Lupus Remission

Advance planning also is important for a healthy pregnancy in women with systemic lupus erythematosus (SLE), Sayna Norouzi, MD, director of the glomerular disease clinic and polycystic kidney disease clinic of Loma Linda University Medical Center, California, said in an interview.

“Lupus mostly affects women of childbearing age and can create many challenges during pregnancy,” said Dr. Norouzi, the corresponding author of a recent review on managing lupus nephritis during pregnancy.

“Women with lupus face an increased risk of pregnancy complications such as preeclampsia, problems with fetal growth, stillbirth, and premature birth, and these risks increase based on factors such as disease activity, certain antibodies in the body, and other baseline existing conditions such as high blood pressure,” she said.

“It can be difficult to distinguish between a lupus flare and pregnancy-related issues, so proper management is important,” she noted. The Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Syndrome and Systemic Lupus Erythematosus (PROMISSE) study findings indicated a lupus nephritis relapse rate of 7.8% of patients in complete remission and 21% of those in partial remission during pregnancy, said Dr. Norouzi. “Current evidence has shown that SLE patients without lupus nephritis flare in the preconception period have a small risk of relapse during pregnancy,” she said.

Before and during pregnancy, women with lupus should work with their treating physicians to adjust medications for safety, watch for signs of flare, and aim to conceive during a period of lupus remission.

Preconception care for women with lupus nephritis involves a careful review of the medications used to control the disease and protect the kidneys and other organs, said Dr. Norouzi.

“Adjustments,” she said, “should be personalized, taking into account the mother’s health and the safety of the baby. Managing the disease actively during pregnancy may require changes to the treatment plan while minimizing risks,” she noted. However, changing medications can cause challenges for patients, as medications that are safer for pregnancy may lead to new symptoms and side effects, and patients will need to work closely with their healthcare providers to overcome new issues that arise, she added.

Preconception lifestyle changes such as increasing exercise and adopting a healthier diet can help with blood pressure control for kidney disease patients, said Dr. Norouzi.

In the review article, Dr. Norouzi and colleagues noted that preconception counseling for patients with lupus should address common comorbidities such as hypertension, diabetes, obesity, and dyslipidemia, and the risk for immediate and long-term cardiovascular complications.
 

Benefits of Preconception Obesity Care Extend to Infants

Current guidelines from the American College of Obstetricians and Gynecologists and the Institute of Medicine advise lifestyle interventions to reduce excessive weight gain during pregnancy and reduce the risk of inflammation, oxidative stress, insulin resistance, and lipotoxicity that can promote complications in the mother and fetus during pregnancy.

In addition, a growing number of studies suggest that women with obesity who make healthy lifestyle changes prior to conception can reduce obesity-associated risks to their infants.

Adults born to women with obesity are at increased risk of cardiovascular disease and early signs of heart remodeling are identifiable in newborns, Samuel J. Burden, PhD, a research associate in the department of women and children’s health, Kings’ College, London, said in an interview. “It is therefore important to investigate whether intervening either before or during pregnancy by promoting a healthy lifestyle can reduce this adverse impact on the heart and blood vessels,” he said.

In a recent study published in the International Journal of Obesity, Dr. Burden and colleagues examined data from eight studies based on data from five randomized, controlled trials including children of mothers with obesity who engaged in healthy lifestyle interventions of improved diet and increased physical activity prior to and during pregnancy. The study population included children ranging in age from less than 2 months to 3-7 years.

Lifestyle interventions for mothers both before conception and during pregnancy were associated with significant changes in cardiac remodeling in the children, notably reduced interventricular septal wall thickness. Additionally, five studies of cardiac systolic function and three studies of diastolic function showed improvement in blood pressure in children of mothers who took part in the interventions.

Dr. Burden acknowledged that lifestyle changes in women with obesity before conception and during pregnancy can be challenging, but should be encouraged. “During pregnancy, it may also seem unnatural to increase daily physical activity or change the way you are eating.” He emphasized that patients should consult their physicians and follow an established program. More randomized, controlled trials are needed from the preconception period to examine whether the health benefits are greater if the intervention begins prior to pregnancy, said Dr. Burden. However, “the current findings indeed indicate that women with obesity who lead a healthy lifestyle before and during their pregnancy can reduce the degree of unhealthy heart remodeling in their children,” he said.

Dr. Seely, Dr. Norouzi, and Dr. Burden had no financial conflicts to disclose.

Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Although studies of drugs have been done to inform preconception care for women with diabetes, research is lacking in several areas, notably the safety of GLP-1 agonists in pregnancy, said Dr. Seely. “This class of drug is commonly used in type 2 diabetes and the current recommendation is to stop these agents 2 months prior to conception,” she said.
 

 

 

Conceive in Times of Lupus Remission

Advance planning also is important for a healthy pregnancy in women with systemic lupus erythematosus (SLE), Sayna Norouzi, MD, director of the glomerular disease clinic and polycystic kidney disease clinic of Loma Linda University Medical Center, California, said in an interview.

“Lupus mostly affects women of childbearing age and can create many challenges during pregnancy,” said Dr. Norouzi, the corresponding author of a recent review on managing lupus nephritis during pregnancy.

“Women with lupus face an increased risk of pregnancy complications such as preeclampsia, problems with fetal growth, stillbirth, and premature birth, and these risks increase based on factors such as disease activity, certain antibodies in the body, and other baseline existing conditions such as high blood pressure,” she said.

“It can be difficult to distinguish between a lupus flare and pregnancy-related issues, so proper management is important,” she noted. The Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Syndrome and Systemic Lupus Erythematosus (PROMISSE) study findings indicated a lupus nephritis relapse rate of 7.8% of patients in complete remission and 21% of those in partial remission during pregnancy, said Dr. Norouzi. “Current evidence has shown that SLE patients without lupus nephritis flare in the preconception period have a small risk of relapse during pregnancy,” she said.

Before and during pregnancy, women with lupus should work with their treating physicians to adjust medications for safety, watch for signs of flare, and aim to conceive during a period of lupus remission.

Preconception care for women with lupus nephritis involves a careful review of the medications used to control the disease and protect the kidneys and other organs, said Dr. Norouzi.

“Adjustments,” she said, “should be personalized, taking into account the mother’s health and the safety of the baby. Managing the disease actively during pregnancy may require changes to the treatment plan while minimizing risks,” she noted. However, changing medications can cause challenges for patients, as medications that are safer for pregnancy may lead to new symptoms and side effects, and patients will need to work closely with their healthcare providers to overcome new issues that arise, she added.

Preconception lifestyle changes such as increasing exercise and adopting a healthier diet can help with blood pressure control for kidney disease patients, said Dr. Norouzi.

In the review article, Dr. Norouzi and colleagues noted that preconception counseling for patients with lupus should address common comorbidities such as hypertension, diabetes, obesity, and dyslipidemia, and the risk for immediate and long-term cardiovascular complications.
 

Benefits of Preconception Obesity Care Extend to Infants

Current guidelines from the American College of Obstetricians and Gynecologists and the Institute of Medicine advise lifestyle interventions to reduce excessive weight gain during pregnancy and reduce the risk of inflammation, oxidative stress, insulin resistance, and lipotoxicity that can promote complications in the mother and fetus during pregnancy.

In addition, a growing number of studies suggest that women with obesity who make healthy lifestyle changes prior to conception can reduce obesity-associated risks to their infants.

Adults born to women with obesity are at increased risk of cardiovascular disease and early signs of heart remodeling are identifiable in newborns, Samuel J. Burden, PhD, a research associate in the department of women and children’s health, Kings’ College, London, said in an interview. “It is therefore important to investigate whether intervening either before or during pregnancy by promoting a healthy lifestyle can reduce this adverse impact on the heart and blood vessels,” he said.

In a recent study published in the International Journal of Obesity, Dr. Burden and colleagues examined data from eight studies based on data from five randomized, controlled trials including children of mothers with obesity who engaged in healthy lifestyle interventions of improved diet and increased physical activity prior to and during pregnancy. The study population included children ranging in age from less than 2 months to 3-7 years.

Lifestyle interventions for mothers both before conception and during pregnancy were associated with significant changes in cardiac remodeling in the children, notably reduced interventricular septal wall thickness. Additionally, five studies of cardiac systolic function and three studies of diastolic function showed improvement in blood pressure in children of mothers who took part in the interventions.

Dr. Burden acknowledged that lifestyle changes in women with obesity before conception and during pregnancy can be challenging, but should be encouraged. “During pregnancy, it may also seem unnatural to increase daily physical activity or change the way you are eating.” He emphasized that patients should consult their physicians and follow an established program. More randomized, controlled trials are needed from the preconception period to examine whether the health benefits are greater if the intervention begins prior to pregnancy, said Dr. Burden. However, “the current findings indeed indicate that women with obesity who lead a healthy lifestyle before and during their pregnancy can reduce the degree of unhealthy heart remodeling in their children,” he said.

Dr. Seely, Dr. Norouzi, and Dr. Burden had no financial conflicts to disclose.

Preconception and prenatal care are more complicated in women with chronic health conditions but attention to disease management and promoting the adoption of a healthier lifestyle can improve outcomes for mothers and infants, according to a growing body of research.

The latest version of the International Federation of Gynecology and Obstetrics Preconception Checklist, published in the International Journal of Gynecology & Obstetrics, highlights preexisting chronic medical conditions such as diabetes, lupus, and obesity as key factors to address in preconception care through disease management. A growing number of studies support the impact of these strategies on short- and long-term outcomes for mothers and babies, according to the authors.
 

Meet Glycemic Control Goals Prior to Pregnancy

“Women with diabetes can have healthy pregnancies but need to prepare for pregnancy in advance,” Ellen W. Seely, MD, professor of medicine at Harvard Medical School and director of clinical research in the endocrinology, diabetes, and hypertension division of Brigham and Women’s Hospital, Boston, said in an interview.

“If glucose levels are running high in the first trimester, this is associated with an increased risk of birth defects, some of which are very serious,” said Dr. Seely. Getting glucose levels under control reduces the risk of birth defects in women with diabetes close to that of the general population, she said.

The American Diabetes Association has set a goal for women to attain an HbA1c of less than 6.5% before conception, Dr. Seely said. “In addition, some women with diabetes may be on medications that should be changed to another class prior to pregnancy,” she noted. Women with type 1 or type 2 diabetes often have hypertension as well, but ACE inhibitors are associated with an increased risk of fetal renal damage that can result in neonatal death; therefore, these medications should be stopped prior to pregnancy, Dr. Seely emphasized.

“If a woman with type 2 diabetes is on medications other than insulin, recommendations from the ADA are to change to insulin prior to pregnancy, since we have the most data on the safety profile of insulin use in pregnancy,” she said.

To help women with diabetes improve glycemic control prior to pregnancy, Dr. Seely recommends home glucose monitoring, with checks of glucose four times a day, fasting, and 2 hours after each meal, and adjustment of insulin accordingly.

A healthy diet and physical activity remain important components of glycemic control as well. A barrier to proper preconception and prenatal care for women with diabetes is not knowing that a pregnancy should be planned, Dr. Seely said. Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Women’s Risk for Lupus Rises With Greater Intake of Ultraprocessed Foods

Article Type
Changed
Thu, 07/11/2024 - 10:28

 

TOPLINE:

A higher intake of ultraprocessed foods increases the risk for systemic lupus erythematosus (SLE) by over 50% in women. The risk doubled in those with anti–double-stranded DNA antibodies.

METHODOLOGY:

  • Researchers assessed 204,175 women from two Nurses’ Health Study cohorts from 1984 to 2016.
  • Participants completed semiquantitative food frequency questionnaires every 4 years for the assessment of dietary intake.
  • Incident SLE cases were self-reported and confirmed using medical records, with 212 cases identified.

TAKEAWAY:

  • A higher cumulative average daily intake of ultraprocessed foods was associated with a 56% increased risk for SLE (95% confidence interval [CI], 1.04-2.32).
  • The risk for anti–double-stranded DNA antibody-positive SLE was more than doubled (hazard ratio, 2.05; 95% CI, 1.15-3.65).
  • Sugar or artificially sweetened beverages were associated with a 45% increased risk for SLE (95% CI, 1.01-2.09).
  • No significant interactions with body mass index were observed in the association between ultraprocessed food intake and SLE.

IN PRACTICE:

This study is too preliminary to have practical application.

SOURCE:

The study was led by Sinara Rossato, PhD, Harvard T.H. Chan School of Public Health, Boston. It was published online in Arthritis Care & Research.

LIMITATIONS:

The study’s generalizability is limited due to the predominantly White female population of registered nurses. The relatively high baseline age of participants may not fully capture the peak incidence age range for SLE. The observational nature of the study cannot establish causality between ultraprocessed food intake and SLE risk.

DISCLOSURES:

The study was supported by the National Institutes of Health. The authors did not declare any competing interests.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

Sustained Low Lupus Disease Activity May Give Lower Risk for Flares, Organ Damage

Article Type
Changed
Tue, 07/09/2024 - 11:37

 

TOPLINE:

A threshold of sustained lupus low disease activity state (LLDAS) or remission for 3 months significantly reduces the risk for damage accrual and flares in patients with systemic lupus erythematosus (SLE), with longer durations offering even greater protection. 

METHODOLOGY:

  • This large, prospective, multicenter study aimed to quantify the impact of sustained LLDAS on irreversible damage and flares.
  • It included 3449 patients (age, ≥ 18 years; 92.2% women) with SLE from 25 centers across 12 countries, analyzing a total of 37,662 visits.
  • Sustained LLDAS or remission was defined as at least two consecutive visits over > 3 months in the respective state.
  • The primary outcome measured was the accrual of irreversible organ damage, with flares as a key secondary outcome.

TAKEAWAY:

  • During a median follow-up of 2.8 years, 80.2% of patients achieved LLDAS at least once, with 72.7% experiencing at least one episode of sustained LLDAS.
  • Sustained LLDAS for > 3 months was linked to a reduced risk for damage accrual (hazard ratio [HR], 0.60; P < .0001).
  • Protection from flares also increased with all durations of sustained LLDAS > 3 months (> 3 months: HR, 0.56; P < .0001; > 36 months: HR, 0.17; P < .0001).
  • Longer periods of sustained LLDAS or remission were associated with significantly higher degrees of protection.

IN PRACTICE:

“These findings support the use of these treat-to-target endpoints in clinical practice and provide a practical target to aim for in SLE treatment,” the authors wrote. 

SOURCE:

The study was led by Vera Golder, MBBS, Monash University, Clayton, Australia. It was published online in The Lancet Rheumatology

LIMITATIONS:

While the study’s large scale and multinational cohort provided robust data, its observational design limited the ability to establish causality. The predominance of Asian ethnicity among the participants may have affected the generalizability of the findings to other populations. Additionally, the median follow-up duration of 2.8 years might not have captured long-term outcomes.

DISCLOSURES:

Some authors declared receiving grants, consulting fees, payments, and honoraria and having other ties with various sources.

CAR T-Cell Treatment Data Expands in Refractory Rheumatic Diseases, Demonstrating Consistent Efficacy

Article Type
Changed
Wed, 08/07/2024 - 16:41

— From a dozen or so studies and sessions devoted to the role of chimeric antigen receptor (CAR) T cells in rheumatic diseases at the annual European Congress of Rheumatology, the message was uniformly positive, supporting growing evidence that drugs in this class are heading toward a paradigm shift in refractory rheumatic diseases.

Of the reports, an update from a 15-patient case series with at least 1 year of follow-up provides “the first long-term evidence of safety and efficacy in multiple rheumatic diseases,” according to Georg Schett, MD, PhD, director of rheumatology and immunology, University of Erlangen-Nürnberg, Erlangen, Germany.

Ted Bosworth/Medscape Medical News
Dr. Georg Schett

The report of high rates of activity and low relative risk of serious adverse events from the same series was published earlier this year in The New England Journal of Medicine when the median follow-up was 15 months. Almost all of the patients have now completed at least 1 year of follow-up and about a third have completed more than 2 years.
 

SLE Is Frequently Targeted in CAR T-Cell Studies

The three rheumatic diseases represented in this series of patients, all of whom had failed multiple previous immune suppressive treatments, were systemic lupus erythematosus (SLE), idiopathic inflammatory myositis (IIM), and systemic sclerosis (SSc). After the autologous T cells were harvested, they were expanded and transfected with the CD19 CAR. The proprietary investigational product, called MB-CART19.1 (Miltenyi Biotec), was administered in a single dose of one million cells per kg bodyweight.

The response rates have been, and continue to be, impressive. For the eight patients with SLE, all achieved the definition of remission in SLE criteria after one dose of treatment. Complete resolution of all major symptom types was achieved after 6 months of follow-up. So far, no patient has relapsed.

For the three patients with IIM, all reached the American College of Rheumatology–EULAR criteria for a major response. All creatine kinase levels had normalized by 3 months. In this group, there was one relapse, which occurred after 18 months of follow-up.

All four patients with SSc achieved a major response on the European Scleroderma Trials and Research (EUSTAR) group activity index. The median reduction from baseline in the EUSTAR score was 4.2 points, and this has been maintained in follow-up to date.
 

Remissions Have Persisted Off All Therapies

These remissions were achieved and maintained after a single dose of CAR T-cell therapy despite discontinuation of all immunosuppressive therapies. With the exception of the single relapse, all remissions have persisted through follow-up to date.

These responses were achieved with manageable side effects, according to Dr. Schett. The most serious adverse event was a grade 4 neutropenia that developed 4 months after receiving CAR T cells. It resolved with granulocyte colony-stimulating factor treatment. Cytokine release syndrome (CRS) has occurred in 10 patients, but it was grade 1 in eight patients and grade 2 in the others. There has been no neurotoxicity.

Almost all patients have experienced an infection during follow-up, but there has been no discernible pattern in relationship to the timing or types of infections. The most common have involved the upper respiratory tract and have been of mild severity, with cases disseminated similarly over early vs late follow-up. There was one case of pneumonia involving antibiotic treatment and a hospital stay, but it resolved.

Dr. Schett acknowledged that safety is a bigger concern in autoimmune diseases, which are often serious but rarely fatal, than in the hematologic malignancies for which CAR T cells were initially tested, but the low rates of serious adverse events in his and other early studies have supported the premise that the risks are not the same.

Asked specifically if CAR T cells can be considered a game changer in autoimmune rheumatic diseases, Dr. Schett was cautious. One reason is the CAR T cells are a complex therapy relative to biologic disease-modifying antirheumatic drugs. He thinks, therefore, that much more data are needed to confirm safety and efficacy. In addition, they are expensive, so it is not yet clear how they will be integrated with other options.

Yet, he thinks the evidence so far suggests a profound effect on the fundamental drivers of autoimmune disease. Their specific mechanism of benefit is still being evaluated, but he considers the clinical responses consistent with a “reset” hypothesis.

After a response, “we are seeing drug-free remissions in some patients as long as they have been followed,” Dr. Schett said. Based on the fact that disease control is being observed off all other therapies, “this only makes sense to me if there is some sort of immunologic reset.”
 

 

 

CAR T-Cell Studies in Autoimmune Diseases Are Proliferating

At last count, there were about 40 studies being performed with CAR T cells in various autoimmune diseases, most of which were rheumatologic disorders, according to Dr. Schett. He noted that funding is coming from multinational drug companies, small biotech startups, and investigator-initiated studies at academic centers.

At EULAR, beyond case studies and anecdotal reports, all of the clinical studies were still at the level of phase 1 or 1/2. Consistent with the data presented by Dr. Schett, the drugs have been nearly uniformly effective, with major responses persisting in patients off other therapies. Adverse events have been manageable.

Examples include a phase 1/2 multinational study with the investigational CAR T-cell therapy YTB323 (Novartis), which demonstrated acceptable safety and a strong signal of benefit in six patients with SLE. In this report, CRS was also common, but no case of CRS was more severe than grade 2. There was no neurotoxicity. Infections did occur but were of relatively mild grades and resolved with treatment.

For efficacy in the ongoing follow-up, SLE symptoms as measured with the SLE Disease Activity Index began to abate at about 14 days after the single-infusion treatment. Improvement on the Physician Global Assessment was also observed between 14 and 28 days. C3 and C4 complement levels started to rise at about 28 days. While the responses have correlated with the observed changes in biomarkers of immune function, they have endured through a median follow-up that now exceeds 6 months.
 

Complete B-Cell Depletion Is Followed by Full Recovery

“Pharmacokinetic and pharmacodynamic studies revealed peak expansion of CAR T cells approximately 13-21 days post infusion, which was accompanied by deep B-cell depletion followed by subsequent B-cell recovery,” reported Josefina Cortés-Hernández, MD, PhD, a senior lecturer at Vall d’Hebron Research Institute, Barcelona, Spain.

Dr. Schett had reported the same pattern of expansion followed by a rapid elimination of detectable CAR T cells despite the sustained clinical benefit.

Dr. Cortés-Hernández said that the signal of efficacy in the context of acceptable safety supports an expansion of clinical studies with this CAR T-cell product in SLE and perhaps other autoimmune disorders.

In another early-stage study, patients with SLE who had failed multiple prior lines of therapy have been enrolled in an ongoing study with a compound CAR (cCAR) T cell. This experimental proprietary product (iCAR Bio Therapeutics, Zhongshan, China) targets both the B-cell maturation antigen and CD19, according to Greg Deener, the chief executive officer of iCell Gene Therapeutics, New York City.

cCAR T-Cell Construct Targets Immune Reset

With this construct, the goal is to deplete long-lived plasma cells as well as B cells in order to achieve a more complete humoral reset. While preliminary data from the phase 1 trial were published earlier this year in Annals of the Rheumatic Diseases, Mr. Deener focused his presentation at EULAR 2024 on 12 patients with SLE and lupus nephritis, a severe form of SLE that threatens glomerular structures and can lead to end-stage liver disease.

B cells in the peripheral blood could not be detected within 10 days of the cCAR infusion, and the immunoglobulins IgM and IgA were undetectable by day 42.

However, after B-cell recovery by day 150, “flow cytometry and B-cell receptor sequencing confirmed full humoral reset was achieved,” Mr. Deener said.

The remission has been durable in 11 of the 12 patients after a mean follow-up of 458 days, Mr. Deener reported. He noted that an improvement in renal function has been observed in the majority of patients.

Like others, he reported that treatment has been relatively well tolerated. In this series of patients, there have been no cases of CRS more severe than grade 1.

Overall, the cCAR data in lupus nephritis support the hypothesis that CAR T cells are reprogramming the immune system, according to Mr. Deener.

Combined with a reasonable safety profile, the consistency of benefit from CAR T cells in autoimmune rheumatic diseases is good news, but all of the investigators who spoke at EULAR agreed that there are still many unanswered questions. Not least, it is unclear whether patients can be effectively and safely retreated when and if relapses occur. Even though Dr. Schett did report a response with retreatment following a relapse, he said that there is no conclusion to draw from a single patient.

Yet, the high rates of remissions in patients with disease refractory to other therapeutic options is highly encouraging, particularly with the manageable side effects now reported by multiple investigators using different CAR T-cell products.

“Roughly 100 patients with rheumatic diseases have been treated with CAR T-cells, and we have not seen a high-grade CRS or neurotoxicity,” he said.

Long-term efficacy is less clear. With the first clinical studies in autoimmune diseases initiated in 2021, few patients have been followed for more than 2 years. Even with the high rates of response that will certainly fuel efforts to rapidly bring these treatments forward, long-term data are now the missing piece.
 

Other Case Series Presented at EULAR

Several other abstracts reported on patients with SSc who were treated with CD19-targeting CAR T cells:

Three patients for whom autologous hematopoietic stem cell transplantation was contraindicated or unsuccessful were successfully and safely treated.

Six patients with diffuse and progressive disease achieved stable disease activity without additional immunosuppression for up to 1 year after treatment.

Dr. Schett reported no potential conflicts of interest, and the study he presented was not funded by industry. Dr. Cortés-Hernández reported a financial relationship with Novartis, which funded the study of the CAR T-cell therapy YTB323, as well as with GlaxoSmithKline, which was not involved in the study she presented.  Mr. Deener is an employee of iCell Gene Therapeutics, which provided funding for the trial he presented.

— From a dozen or so studies and sessions devoted to the role of chimeric antigen receptor (CAR) T cells in rheumatic diseases at the annual European Congress of Rheumatology, the message was uniformly positive, supporting growing evidence that drugs in this class are heading toward a paradigm shift in refractory rheumatic diseases.

Of the reports, an update from a 15-patient case series with at least 1 year of follow-up provides “the first long-term evidence of safety and efficacy in multiple rheumatic diseases,” according to Georg Schett, MD, PhD, director of rheumatology and immunology, University of Erlangen-Nürnberg, Erlangen, Germany.

The report of high rates of activity and low relative risk of serious adverse events from the same series was published earlier this year in The New England Journal of Medicine when the median follow-up was 15 months. Almost all of the patients have now completed at least 1 year of follow-up and about a third have completed more than 2 years.
 

SLE Is Frequently Targeted in CAR T-Cell Studies

The three rheumatic diseases represented in this series of patients, all of whom had failed multiple previous immune suppressive treatments, were systemic lupus erythematosus (SLE), idiopathic inflammatory myositis (IIM), and systemic sclerosis (SSc). After the autologous T cells were harvested, they were expanded and transfected with the CD19 CAR. The proprietary investigational product, called MB-CART19.1 (Miltenyi Biotec), was administered in a single dose of one million cells per kg bodyweight.

The response rates have been, and continue to be, impressive. For the eight patients with SLE, all achieved the definition of remission in SLE criteria after one dose of treatment. Complete resolution of all major symptom types was achieved after 6 months of follow-up. So far, no patient has relapsed.

For the three patients with IIM, all reached the American College of Rheumatology–EULAR criteria for a major response. All creatine kinase levels had normalized by 3 months. In this group, there was one relapse, which occurred after 18 months of follow-up.

All four patients with SSc achieved a major response on the European Scleroderma Trials and Research (EUSTAR) group activity index. The median reduction from baseline in the EUSTAR score was 4.2 points, and this has been maintained in follow-up to date.
 

Remissions Have Persisted Off All Therapies

These remissions were achieved and maintained after a single dose of CAR T-cell therapy despite discontinuation of all immunosuppressive therapies. With the exception of the single relapse, all remissions have persisted through follow-up to date.

These responses were achieved with manageable side effects, according to Dr. Schett. The most serious adverse event was a grade 4 neutropenia that developed 4 months after receiving CAR T cells. It resolved with granulocyte colony-stimulating factor treatment. Cytokine release syndrome (CRS) has occurred in 10 patients, but it was grade 1 in eight patients and grade 2 in the others. There has been no neurotoxicity.

Almost all patients have experienced an infection during follow-up, but there has been no discernible pattern in relationship to the timing or types of infections. The most common have involved the upper respiratory tract and have been of mild severity, with cases disseminated similarly over early vs late follow-up. There was one case of pneumonia involving antibiotic treatment and a hospital stay, but it resolved.

Dr. Schett acknowledged that safety is a bigger concern in autoimmune diseases, which are often serious but rarely fatal, than in the hematologic malignancies for which CAR T cells were initially tested, but the low rates of serious adverse events in his and other early studies have supported the premise that the risks are not the same.

Asked specifically if CAR T cells can be considered a game changer in autoimmune rheumatic diseases, Dr. Schett was cautious. One reason is the CAR T cells are a complex therapy relative to biologic disease-modifying antirheumatic drugs. He thinks, therefore, that much more data are needed to confirm safety and efficacy. In addition, they are expensive, so it is not yet clear how they will be integrated with other options.

Yet, he thinks the evidence so far suggests a profound effect on the fundamental drivers of autoimmune disease. Their specific mechanism of benefit is still being evaluated, but he considers the clinical responses consistent with a “reset” hypothesis.

After a response, “we are seeing drug-free remissions in some patients as long as they have been followed,” Dr. Schett said. Based on the fact that disease control is being observed off all other therapies, “this only makes sense to me if there is some sort of immunologic reset.”
 

 

 

CAR T-Cell Studies in Autoimmune Diseases Are Proliferating

At last count, there were about 40 studies being performed with CAR T cells in various autoimmune diseases, most of which were rheumatologic disorders, according to Dr. Schett. He noted that funding is coming from multinational drug companies, small biotech startups, and investigator-initiated studies at academic centers.

At EULAR, beyond case studies and anecdotal reports, all of the clinical studies were still at the level of phase 1 or 1/2. Consistent with the data presented by Dr. Schett, the drugs have been nearly uniformly effective, with major responses persisting in patients off other therapies. Adverse events have been manageable.

Examples include a phase 1/2 multinational study with the investigational CAR T-cell therapy YTB323 (Novartis), which demonstrated acceptable safety and a strong signal of benefit in six patients with SLE. In this report, CRS was also common, but no case of CRS was more severe than grade 2. There was no neurotoxicity. Infections did occur but were of relatively mild grades and resolved with treatment.

For efficacy in the ongoing follow-up, SLE symptoms as measured with the SLE Disease Activity Index began to abate at about 14 days after the single-infusion treatment. Improvement on the Physician Global Assessment was also observed between 14 and 28 days. C3 and C4 complement levels started to rise at about 28 days.

Form of B12 Deficiency Affecting the Central Nervous System May Be New Autoimmune Disease

Article Type
Changed
Mon, 07/01/2024 - 13:53

Researchers have identified a form of B12 deficiency caused by autoantibodies that specifically affects the central nervous system.

Discovered while studying a puzzling case of one patient with inexplicable neurological systems, the same autoantibody was detected in a small percentage of healthy individuals and was nearly four times as prevalent in patients with neuropsychiatric systemic lupus erythematosus (SLE).

“I didn’t think this single investigation was going to yield a broader phenomenon with other patients,” lead author John V. Pluvinage, MD, PhD, a neurology resident at the University of California San Francisco, said in an interview. “It started as an N-of-one study just based on scientific curiosity.”

“It’s a beautifully done study,” added Betty Diamond, MD, director of the Institute of Molecular Medicine at the Feinstein Institutes for Medical Research in Manhasset, New York, commenting on the research. It uncovers “yet another example of a disease where antibodies getting into the brain are the problem.”

The research was published in Science Translational Medicine.
 

The Patient

The investigation began in 2014 with a 67-year-old woman presenting with difficulty speaking, ataxia, and tremor. Her blood tests showed no signs of B12 deficiency, and testing for known autoantibodies came back negative.

Solving this mystery required a more exhaustive approach. The patient enrolled in a research study focused on identifying novel autoantibodies in suspected neuroinflammatory disease, using a screening technology called phage immunoprecipitation sequencing.

“We adapted this technology to screen for autoantibodies in an unbiased manner by displaying every peptide across the human proteome and then mixing those peptides with patient antibodies in order to figure out what the antibodies are binding to,” explained Dr. Pluvinage.

Using this method, he and colleagues discovered that this woman had autoantibodies that target CD320 — a receptor important in the cellular uptake of B12. While her blood tests were normal, B12 in the patient’s cerebral spinal fluid (CSF) was “nearly undetectable,” Dr. Pluvinage said. Using an in vitro model of the blood-brain barrier (BBB), the researchers determined that anti-CD320 impaired the transport of B12 across the BBB by targeting receptors on the cell surface.

Treating the patient with a combination of immunosuppressant medication and high-dose B12 supplementation increased B12 levels in the patient’s CSF and improved clinical symptoms.
 

Identifying More Cases

Dr. Pluvinage and colleagues tested the 254 other individuals enrolled in the neuroinflammatory disease study and identified seven participants with CSF anti-CD320 autoantibodies — four of whom had low B12 in the CSF.

In a group of healthy controls, anti-CD320 seropositivity was 6%, similar to the positivity rate in 132 paired serum and CSF samples from a cohort of patients with multiple sclerosis (5.7%). In this group of patients with multiple sclerosis, anti-CD320 presence in the blood was highly predictive of high levels of CSF methylmalonic acid, a metabolic marker of B12 deficiency.

Researchers also screened for anti-CD320 seropositivity in 408 patients with non-neurologic SLE and 28 patients with neuropsychiatric SLE and found that the autoantibody was nearly four times as prevalent in patients with neurologic symptoms (21.4%) compared with in those with non-neurologic SLE (5.6%).

“The clinical relevance of anti-CD320 in healthy controls remains uncertain,” the authors wrote. However, it is not uncommon to have healthy patients with known autoantibodies.

“There are always people who have autoantibodies who don’t get disease, and why that is we don’t know,” said Dr. Diamond. Some individuals may develop clinical symptoms later, or there may be other reasons why they are protected against disease.

Pluvinage is eager to follow some seropositive healthy individuals to track their neurologic health overtime, to see if the presence of anti-CD320 “alters their neurologic trajectories.”
 

 

 

Alternative Pathways

Lastly, Dr. Pluvinage and colleagues set out to explain why patients with anti-CD320 in their blood did not show any signs of B12 deficiency. They hypothesized that another receptor may be compensating and still allowing blood cells to take up B12. Using CRISPR screening, the team identified the low-density lipoprotein receptor as an alternative pathway to B12 uptake.

“These findings suggest a model in which anti-CD320 impairs transport of B12 across the BBB, leading to autoimmune B12 central deficiency (ABCD) with varied neurologic manifestations but sparing peripheral manifestations of B12 deficiency,” the authors wrote.

The work was supported by the National Institute of Mental Health, National Center for Chronic Disease Prevention and Health Promotion, Department of Defense, UCSF Helen Diller Family Comprehensive Cancer Center Laboratory for Cell Analysis Shared Resource Facility, National Multiple Sclerosis Society, Valhalla Foundation, and the Westridge Foundation. Dr. Pluvinage is a co-inventor on a patent application related to this work. Dr. Diamond had no relevant disclosures.

In a group of healthy controls, anti-CD320 seropositivity was 6%, similar to the positivity rate in 132 paired serum and CSF samples from a cohort of patients with multiple sclerosis (5.7%). In this group of patients with multiple sclerosis, anti-CD320 presence in the blood was highly predictive of high levels of CSF methylmalonic acid, a metabolic marker of B12 deficiency.

Researchers also screened for anti-CD320 seropositivity in 408 patients with non-neurologic SLE and 28 patients with neuropsychiatric SLE and found that the autoantibody was nearly four times as prevalent in patients with neurologic symptoms (21.4%) compared with in those with non-neurologic SLE (5.6%).

“The clinical relevance of anti-CD320 in healthy controls remains uncertain,” the authors wrote. However, it is not uncommon to have healthy patients with known autoantibodies.

“There are always people who have autoantibodies who don’t get disease, and why that is we don’t know,” said Dr. Diamond. Some individuals may develop clinical symptoms later, or there may be other reasons why they are protected against disease.

Pluvinage is eager to follow some seropositive healthy individuals to track their neurologic health overtime, to see if the presence of anti-CD320 “alters their neurologic trajectories.”
 

 

 

Alternative Pathways

Lastly, Dr. Pluvinage and colleagues set out to explain why patients with anti-CD320 in their blood did not show any signs of B12 deficiency. They hypothesized that another receptor may be compensating and still allowing blood cells to take up B12. Using CRISPR screening, the team identified the low-density lipoprotein receptor as an alternative pathway to B12 uptake.

“These findings suggest a model in which anti-CD320 impairs transport of B12 across the BBB, leading to autoimmune B12 central deficiency (ABCD) with varied neurologic manifestations but sparing peripheral manifestations of B12 deficiency,” the authors wrote.

The work was supported by the National Institute of Mental Health, National Center for Chronic Disease Prevention and Health Promotion, Department of Defense, UCSF Helen Diller Family Comprehensive Cancer Center Laboratory for Cell Analysis Shared Resource Facility, National Multiple Sclerosis Society, Valhalla Foundation, and the Westridge Foundation. Dr. Pluvinage is a co-inventor on a patent application related to this work. Dr. Diamond had no relevant disclosures.

Researchers have identified a form of B12 deficiency caused by autoantibodies that specifically affects the central nervous system.

Discovered while studying a puzzling case of one patient with inexplicable neurological systems, the same autoantibody was detected in a small percentage of healthy individuals and was nearly four times as prevalent in patients with neuropsychiatric systemic lupus erythematosus (SLE).

“I didn’t think this single investigation was going to yield a broader phenomenon with other patients,” lead author John V. Pluvinage, MD, PhD, a neurology resident at the University of California San Francisco, said in an interview. “It started as an N-of-one study just based on scientific curiosity.”

“It’s a beautifully done study,” added Betty Diamond, MD, director of the Institute of Molecular Medicine at the Feinstein Institutes for Medical Research in Manhasset, New York, commenting on the research. It uncovers “yet another example of a disease where antibodies getting into the brain are the problem.”

The research was published in Science Translational Medicine.
 

The Patient

The investigation began in 2014 with a 67-year-old woman presenting with difficulty speaking, ataxia, and tremor. Her blood tests showed no signs of B12 deficiency, and testing for known autoantibodies came back negative.

Solving this mystery required a more exhaustive approach. The patient enrolled in a research study focused on identifying novel autoantibodies in suspected neuroinflammatory disease, using a screening technology called phage immunoprecipitation sequencing.

“We adapted this technology to screen for autoantibodies in an unbiased manner by displaying every peptide across the human proteome and then mixing those peptides with patient antibodies in order to figure out what the antibodies are binding to,” explained Dr. Pluvinage.

Using this method, he and colleagues discovered that this woman had autoantibodies that target CD320 — a receptor important in the cellular uptake of B12. While her blood tests were normal, B12 in the patient’s cerebral spinal fluid (CSF) was “nearly undetectable,” Dr. Pluvinage said. Using an in vitro model of the blood-brain barrier (BBB), the researchers determined that anti-CD320 impaired the transport of B12 across the BBB by targeting receptors on the cell surface.

Treating the patient with a combination of immunosuppressant medication and high-dose B12 supplementation increased B12 levels in the patient’s CSF and improved clinical symptoms.

‘Therapeutic Continuums’ Guide Systemic Sclerosis Treatment in Updated EULAR Recommendations

Article Type

Wed, 06/26/2024 - 11:41

– The use of immunosuppressive and antifibrotic drugs to treat skin and lung fibrosis leads updated recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the treatment of systemic sclerosis.

“The most impactful new recommendation relates to the evidence for immunosuppressive agents and antifibrotics for the treatment of skin fibrosis and lung fibrosis,” said Francesco Del Galdo, MD, PhD, professor of experimental medicine, consultant rheumatologist, and scleroderma and connective tissue diseases specialist at Leeds Teaching Hospitals NHS Trust, Leeds, England. Dr. Del Galdo presented the update at the annual European Congress of Rheumatology.

“But there are also new recommendations, including a redefined target population for hematopoietic stem cell transplantation following cyclophosphamide, the upfront combination treatment at the time of diagnosis of pulmonary arterial hypertension [PAH], and a negative recommendation for the use of anticoagulants for pulmonary arterial hypertension,” noted Dr. Del Galdo, highlighting key updates in the 2024 recommendations.

Robert B.M. Landewé, MD, PhD, professor and rheumatologist at Amsterdam University Medical Center, Amsterdam, the Netherlands, and Zuyderland Medical Center, Heerlen, the Netherlands, co-moderated the session on EULAR recommendations. “The management of systemic sclerosis is a field in which a lot is happening,” he said. “The last update goes back to 2017, and in the meantime, many new approaches have seen the light, especially pertaining to skin fibrosis and interstitial lung disease. Six new recommendations have been coined, covering drugs like mycophenolate mofetil, nintedanib, rituximab, and tocilizumab. None of these therapies were present in the 2017 recommendations. It seems the field is now ready to further expand on targeted therapies for the management of musculoskeletal and gastrointestinal manifestations, calcinosis, and the local management of digital ulcers.”
 

‘Therapeutic Continuums’ Aid Disease Management

Dr. Del Galdo and his colleagues grouped the various interventions across what the recommendations label as evidence-backed “therapeutic continuums.” These span six of the eight different clinical manifestations of systemic sclerosis: Raynaud’s phenomenon, digital ulcers, pulmonary hypertension, musculoskeletal manifestations, skin fibrosis, interstitial lung disease (ILD), and gastrointestinal and renal crisis.

A slide showing the different strengths of evidence for various drugs across the eight manifestations illustrated the principle behind the therapeutic continuums. “These ‘therapeutic continuums’ suggest a common pathogenetic mechanism driving the various manifestations of disease,” said Dr. Del Galdo. For example, he noted, “If rituximab had a positive response in skin and in lung, it suggests that B cells play a role in the clinical manifestations of skin and lung in this disease.”

Dr. Del Galdo highlighted the new immunosuppression continuum and associated treatments for skin and lung fibrosis. “For skin involvement, the task force recommended mycophenolate, methotrexate, and rituximab, with tocilizumab having a lower level of evidence and lower recommendation strength; similarly, in interstitial lung disease, we have rituximab, mycophenolate, cyclophosphamide, and nintedanib, and these all have the highest strength of evidence. Tocilizumab is assigned one strength of evidence below the other drugs.”

He also cited the phosphodiesterase 5 inhibitor (PDE5i) drugs that are used across Raynaud’s phenomenon, digital ulcers, and pulmonary arterial hypertension, which together form a vascular therapeutic continuum.

The complexity of systemic sclerosis and multiple manifestations was a major determinant of the recommendations, Dr. Del Galdo pointed out. “The task force realized that since this is such a complex disease, we cannot recommend one treatment unconditionally. For example, with mycophenolate mofetil, what works for most patients for the skin and lung manifestations might not for someone who experiences severe diarrhea, in which mycophenolate is contraindicated. So, the highest degree of recommendation that the task force felt comfortable with was ‘should be considered.’ ”

Dr. Del Galdo stressed that the complex nature of systemic sclerosis means that “when thinking of treating one manifestation, you also always need to consider all the other clinical manifestations as experienced by the patient, and it is this multifaceted scenario that will ultimately lead to your final choice.”

Turning to new evidence around drug use, Dr. Del Galdo said that rituximab has the highest level of evidence across skin and lung manifestations, nintedanib is new in lung, and tocilizumab is new across both skin and lung.

To treat systemic sclerosis–pulmonary arterial hypertension (SSc-PAH), as long as there are no contraindications, the task force recommends using PDE5i and endothelin receptor antagonists (ERAs) at diagnosis. Data from phase 3 trials show a better outcome when the combination is established early.

The task force suggests avoiding the use of warfarin in PAH. “This is supported by a signal from two trials showing an increase in morbidity and mortality in these patients,” noted Dr. Del Galdo.

He also pointed out that selexipag and riociguat were new and important second-line additions for the treatment of PAH, and — consistent with the ERA approach — the EULAR recommendation supports frequent follow-up to establish a treat-to-target approach to maximizing clinical outcomes in SSc-PAH and SSc-ILD. “Specifically, for the first time, we recommend monitoring the effect of any chosen intervention selected within 3-6 months of starting. The evidence suggests there is a group of patients who respond and some who respond less well and who might benefit from a second-line intervention.”

For example, results of one trial support the approach of adding an antifibrotic agent to reduce progression in people with progressive lung fibrosis. “Similarly, for pulmonary hypertension, we recommend putting patients on dual treatment, and if this fails, place them on selexipag or switch the PDE5i to riociguat,” Dr. Del Galdo said.
 

 

 

Systemic Sclerosis Research Agenda and Recommendations Align

Dr. Del Galdo highlighted the value of therapeutic continuums in advancing disease understanding. “It is starting to teach us what we know and what we don’t and where do we need to build more evidence. Effectively, they determine where the gaps in therapy lie, and this starts to guide the research agenda.

“In fact, what is really interesting about this recommendation update — certainly from the perspective of disease understanding — is that we are starting to have a bird’s-eye view of the clinical manifestations of scleroderma that have so often been dealt with separately. Now we are starting to build a cumulative evidence map of this disease.”

In 2017, the research agenda largely advocated identifying immune-targeting drugs for skin and lung fibrosis, Dr. Del Galdo pointed out. “Now, we’ve done that — we’ve identified appropriate immunosuppressive drugs — and this is testimony to the importance of these recommendations because what prioritized the research agenda 10 years ago ended up informing the clinical trials and made it into the recommendations.”

“We definitely are one step forward compared to this 2017 recommendation and closer to what we would like to do,” he asserted.
 

Remission Elusive but Getting Closer

In some respects, according to Dr. Del Galdo, research and development is making relatively slow progress, especially compared with other rheumatologic diseases such as rheumatoid arthritis. “We cannot put patients with systemic sclerosis in remission yet. But I think we are one step ahead in that we’ve now established the treat-to-target approach to maximize the efficacy with which we can stall disease progression, but we cannot yet put these patients into remission,” he said. Systemic sclerosis has multiple manifestations, and fibrotic damage cannot be reversed. “Right now, the scar will remain there forever,” he noted.

Until remission is achievable, Dr. Del Galdo advises diagnosing and treating patients earlier to prevent fibrotic manifestations.

Dr. Del Galdo explained the three leading priorities on the systemic sclerosis research agenda. “There are three because it is such a complex disease. The first is considering the patient voice — this is the most important one, and the patients say they want a more holistic approach — so trialing and treating multiple manifestations together.”

Second, Dr. Del Galdo said, he would like to see a patient-reported measure developed that can capture the entire disease.

Third, from a physician’s point of view, Dr. Del Galdo said, “We want to send the patients into remission. We need to continue to further deconvolute the clinical manifestations and find the bottleneck at the beginning of the natural history of disease.

“If we can find a drug that is effective very early on, before the patients start getting the eight different manifestations with different levels of severity, then we will be on the right road, which we hope will end in remission.”

Dr. Del Galdo has served on the speakers bureau for AstraZeneca and Janssen; consulted for AstraZeneca, Boehringer Ingelheim, Capella, Chemomab, Janssen, and Mitsubishi-Tanabe; and received grant or research support from AbbVie, AstraZeneca, Boheringer Ingelheim, Capella, Chemomab, Kymab, Janssen, and Mitsubishi-Tanabe. Dr. Landewé had no relevant disclosures.

TOPLINE:

A study reveals that hydroxychloroquine levels during the first trimester in pregnant women with systemic lupus erythematosus (SLE) are linked to severe maternal flares but not to adverse pregnancy outcomes.

METHODOLOGY:

  • Researchers included pregnant women with SLE (median age, 32.1 years; median duration of disease, 8.3 years) who were enrolled in an ongoing French prospective observational study and were receiving hydroxychloroquine.
  • The study assessed hydroxychloroquine blood levels during the first trimester. It defined severe nonadherence as having levels < 200 ng/mL and classified levels < 500 ng/mL as subtherapeutic.
  • Primary outcomes were maternal flares during pregnancy and adverse pregnancy outcomes, including fetal/neonatal death and preterm delivery.

TAKEAWAY:

  • Overall, 32 women experienced at least one flare during the second and third trimester; four had severe flares.
  • The rates of severe maternal SLE flares were significantly associated with hydroxychloroquine levels in the first trimester that were classified as subtherapeutic (8.8% vs 0.7% with above subtherapeutic levels, P = .02) and severely nonadherent (13.3% vs 1.3% with above severely nonadherent levels, P = .04).
  • There was no significant difference in adverse pregnancy outcomes by hydroxychloroquine level, suggesting its specific effect on maternal health rather than fetal health.

IN PRACTICE:

According to the authors, “this study supports hydroxychloroquine blood level assessment in pregnant women with SLE, as a predictor of severe maternal disease activity in pregnancy.”

SOURCE:

The study was led by Gelsomina Alle, MD, Assistance Publique-Hôpitaux de Paris, Paris, France. It was published online in Rheumatology.

LIMITATIONS:

The study’s sample size limited the ability to perform multivariate analyses for severe flares. Patients had to have an ongoing pregnancy at 12 weeks to be included, potentially excluding those with early pregnancy loss. The study only observed first-trimester hydroxychloroquine levels, not accounting for adherence variations throughout pregnancy.

DISCLOSURES:

The study funding source was not disclosed. Several authors declared financial relationships with pharmaceutical companies, including research support and consulting fees.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

Sex-Related Differences Found in IgG4-Related Disease Epidemiology

Article Type

Mon, 06/24/2024 - 14:27

 

TOPLINE:

Men with immunoglobulin G4 (IgG4)-related disease exhibit significantly lower serum lipase levels and a greater likelihood of organ involvement than women, highlighting significant sex-dependent differences in disease manifestations.

METHODOLOGY:

  • Researchers conducted a retrospective study of 328 patients (69% men) diagnosed with IgG4-related disease at the Massachusetts General Hospital – Rheumatology Clinic, Boston, who met the American College of Rheumatology–European Alliance of Associations for Rheumatology (ACR-EULAR) classification criteria between January 2008 and May 2023.
  • Among the 328 patients, 69% were men and 31% were women, with a significant male-to-female ratio of 2.2:1.0. Men were typically older at diagnosis (median age, 63.7 vs 58.2 years).
  • Data on serum lipase levels, renal involvement, and other clinical and laboratory parameters were collected.

TAKEAWAY:

  • Men had higher baseline ACR-EULAR scores, indicating more severe disease (median score of 35.0 vs 29.5; P = .0010).
  • Male patients demonstrated a median baseline serum lipase concentration of 24.5 U/L, significantly lower than the 33.5 U/L observed in women.
  • Pancreatic (50% vs 26%) or renal (36% vs 18%) involvement was more common in men.
  • Men exhibited higher IgG4 levels (P = .0050) and active B-cell responses in the blood (P = .0095).

IN PRACTICE:

According to the authors, this work confirms “the impression of an important sex disparity among patients with IgG4-related disease, with most patients being male, and male patients demonstrating strong tendencies toward more severe disease than female patients.”

SOURCE:

The study was led by Isha Jha, MD, Massachusetts General Hospital, Boston. It was published online on May 30, 2024, in The Lancet Rheumatology

LIMITATIONS:

The study’s retrospective design may limit the ability to establish causality between sex differences and IgG4-related disease manifestations. A relatively small percentage of patients were assessed before receiving any immunosuppressive treatment, potentially influencing the observed clinical parameters.

DISCLOSURES:

This work was supported by the National Institutes of Health/National Institute of Allergy and Infectious Diseases, the Rheumatology Research Foundation, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Some authors declared financial ties outside this work.

Autoantibodies Nonspecific to Systemic Sclerosis May Play Role in ILD Prediction

Article Type
Changed
Fri, 06/14/2024 - 14:44

 

— Anti-Ro/SSA antibodies may help predict which patients with systemic sclerosis (SSc) are at a greater risk for interstitial lung disease (ILD) and may serve as a biomarker to guide screening, according to an analysis of data from a large European cohort.

The researchers were led by Blaž Burja, MD, PhD, a physician-scientist at the Center of Experimental Rheumatology, University Hospital Zürich, Switzerland, who reported that anti-Ro/SSA antibodies are a risk factor for ILD, with an odds ratio of 1.24, in patients with SSc.

At the annual European Congress of Rheumatology, he presented the findings of the study that aimed to find out if SSc-nonspecific antibodies might help better risk-stratify patients with SSc, focusing on lung involvement. “Among them, anti-Ro/SSA antibodies have been shown to be associated with interstitial lung disease in different connective tissue diseases,” Dr. Burja pointed out.

“A total of 15% of all patients in the SSc cohort presented with anti-Ro/SSA antibodies, and this subgroup presented with distinct clinical features: Importantly, higher prevalence of ILD and lower DLCO% [diffusing capacity of the lungs for carbon monoxide] in patients with established ILD,” reported Dr. Burja. “However, these anti-Ro/SSA antibodies do not predict ILD progression, death, or overall disease progression.”

Based on the findings, Dr. Burja suggested that these antibodies be incorporated into routine clinical practice to identify patients with SSc who have a high risk for ILD. He noted that “this has specific importance in clinical settings without availability of high-resolution computed tomography (HRCT), where anti-Ro/SSA antibodies could represent an additional biomarker to guide the screening process, in particular, in patients without SSc-specific antibodies.”

Caroline Ospelt, MD, PhD, co-moderator of the session and scientific program chair of EULAR 2024, told this news organization that the study was unique in its approach to studying ILD risk by “looking outside the box, so not just at specific antibodies but whether cross-disease antibodies may have value in stratifying patients and help predict risk of lung involvement and possibly monitor these patients.”

Dr. Ospelt, professor of experimental rheumatology at University Hospital Zürich, who was not involved in the study, noted: “It might also be the case that we could adapt this concept and use these antibodies in other rheumatic diseases, too, not just systemic sclerosis, to predict lung involvement.”
 

Risk-Stratifying With SSc-Nonspecific Antibodies

Dr. Burja explained that despite better stratification of patients with SSc with SSc-specific antibodies, “in clinical practice, we see large heterogeneity, and individual prognosis with regards to outcomes is still unpredictable, so we wanted to know whether by using nonspecific autoantibodies we might be better able to risk-stratify these patients.”

A study population of 4421 with at least one follow-up visit, including 3060 patients with available follow-up serologic data, was drawn from the European Scleroderma Trials and Research group database (n = 22,482). Of these 3060 patients, 461 were positive for anti-Ro/SSA antibodies and 2599 were negative. The researchers analyzed the relationships between baseline characteristics and the development or progression of ILD over 2.7 years of follow-up. Incident, de novo ILD was defined based on its presence on HRCT, and progression was defined by whether the percentage of predicted forced vital capacity (FVC%) dropped ≥ 10%, FVC% dropped 5%-9% in association with a DLCO% drop ≥ 15%, or FVC% dropped > 5%. Deaths from all causes and prognostic factors for the progression of lung fibrosis during follow-up were recorded.
 

 

 

High Prevalence of ILD With Anti-Ro/SSA Antibodies in SSc

At baseline, patients with anti-Ro/SSA antibodies were aged 55-56 years, 84%-87% were women, and muscular involvement was present in 18% of patients positive for anti-Ro/SSA antibodies and 12.5% of those who were negative (P < .001). According to HRCT, ILD was present in 56.2% of patients positive for anti-Ro/SSA antibodies and in 47.8% of those who were negative (P = .001). FVC% was 92.5% in patients positive for anti-Ro/SSA antibodies and 95.7% in those who were negative (P = .002). DLCO% was 66.9% in patients positive for anti-Ro/SSA antibodies and 71% in those who were negative (P < .001).

“A total of 15% of all SSc patients presented as positive for anti-Ro/SSA antibodies, and these patients all presented with higher prevalence of SSA-nonspecific antibodies, too: Of note, those with anti-La/SSB and anti-U1/RNP and rheumatoid factor,” Dr. Burja reported.

In patients with anti-U1/RNP autoantibodies, 1% were positive and 4% were negative for anti-Ro/SSA antibodies; in those with anti-La/SSB autoantibodies, 17% were positive and 1% were negative for anti-Ro/SSA antibodies; and in those with rheumatoid factor, 28% were positive and 14% were negative for anti-Ro/SSA antibodies.

Dr. Burja pointed out that the average disease duration in the study cohort at baseline was 7 years, “and at this timepoint, we expect to see some common disease manifestations. Specifically, higher muscular involvement and higher ILD based on HRCT.

“We decided to focus on patients with established ILD at baseline,” said Dr. Burja. “Anti-Ro/SSA-positive patients with established ILD at baseline presented with lower DLCO values at 59% in patients positive for anti-Ro/SSA antibodies and 61% for those who were negative.”

After conducting a multivariable analysis of 14,066 healthcare visits and adjusting for known risk factors for ILD, the researchers concluded that anti-Ro/SSA antibodies are an independent risk factor for ILD, with an odds ratio of 1.24 (95% CI, 1.07-1.44; P = .006). They also determined that anti-Ro/SSA antibodies are a risk factor for lower DLCO values in patients with ILD, with a regression coefficient of −1.93.

The researchers then explored the progression of ILD and overall disease progression and survival during the follow-up period in a longitudinal analysis. “However, anti-Ro/SSA antibodies were not found to predict the progression of ILD,” reported Dr. Burja, adding that this was true regardless of the definition of ILD progression used. “Nor did anti-Ro/SSA antibodies do not predict survival or overall disease progression.”

Dr. Burja pointed out the limitations in his study, including the lack of standardized criteria for all centers to assess anti-Ro/SSA positivity; there was a lack of discrimination between anti-Ro52 and anti-Ro60 subtypes, and there were no standardized applicable criteria to study lung progression in SSc.

Dr. Burja and Dr. Ospelt had no relevant financial disclosures.

At baseline, patients with anti-Ro/SSA antibodies were aged 55-56 years, 84%-87% were women, and muscular involvement was present in 18% of patients positive for anti-Ro/SSA antibodies and 12.5% of those who were negative (P < .001). According to HRCT, ILD was present in 56.2% of patients positive for anti-Ro/SSA antibodies and in 47.8% of those who were negative (P = .001). FVC% was 92.5% in patients positive for anti-Ro/SSA antibodies and 95.7% in those who were negative (P = .002). DLCO% was 66.9% in patients positive for anti-Ro/SSA antibodies and 71% in those who were negative (P < .001).

“A total of 15% of all SSc patients presented as positive for anti-Ro/SSA antibodies, and these patients all presented with higher prevalence of SSA-nonspecific antibodies, too: Of note, those with anti-La/SSB and anti-U1/RNP and rheumatoid factor,” Dr. Burja reported.

In patients with anti-U1/RNP autoantibodies, 1% were positive and 4% were negative for anti-Ro/SSA antibodies; in those with anti-La/SSB autoantibodies, 17% were positive and 1% were negative for anti-Ro/SSA antibodies; and in those with rheumatoid factor, 28% were positive and 14% were negative for anti-Ro/SSA antibodies.

Dr. Burja pointed out that the average disease duration in the study cohort at baseline was 7 years, “and at this timepoint, we expect to see some common disease manifestations. Specifically, higher muscular involvement and higher ILD based on HRCT.

“We decided to focus on patients with established ILD at baseline,” said Dr. Burja. “Anti-Ro/SSA-positive patients with established ILD at baseline presented with lower DLCO values at 59% in patients positive for anti-Ro/SSA antibodies and 61% for those who were negative.”

After conducting a multivariable analysis of 14,066 healthcare visits and adjusting for known risk factors for ILD, the researchers concluded that anti-Ro/SSA antibodies are an independent risk factor for ILD, with an odds ratio of 1.24 (95% CI, 1.07-1.44; P = .006). They also determined that anti-Ro/SSA antibodies are a risk factor for lower DLCO values in patients with ILD, with a regression coefficient of −1.93.

The researchers then explored the progression of ILD and overall disease progression and survival during the follow-up period in a longitudinal analysis. “However, anti-Ro/SSA antibodies were not found to predict the progression of ILD,” reported Dr. Burja, adding that this was true regardless of the definition of ILD progression used. “Nor did anti-Ro/SSA antibodies do not predict survival or overall disease progression.”

Dr. Burja pointed out the limitations in his study, including the lack of standardized criteria for all centers to assess anti-Ro/SSA positivity; there was a lack of discrimination between anti-Ro52 and anti-Ro60 subtypes, and there were no standardized applicable criteria to study lung progression in SSc.

Dr. Burja and Dr. Ospelt had no relevant financial disclosures.
