VIENNA — Physicians are called to record clinical details of patients with asthma undergoing biologic therapy to monitor clinical remission and keep an eye on eosinophilic granulomatosis with polyangiitis (EGPA) symptoms as patients come off the medications, according to pulmonary experts presenting at the European Respiratory Society (ERS) 2024 International Congress.

Biologics have revolutionized the treatment of severe asthma, significantly improving patient outcomes. However, the focus has recently shifted toward achieving more comprehensive disease control. Remission, already a well-established goal in conditions like rheumatoid arthritis and inflammatory bowel disease, is now being explored in patients with asthma receiving biologics.

Peter Howarth, medical director at Global Medical, Specialty Medicine, GSK, in Brentford, England, said that new clinical remission criteria in asthma may be overly rigid and of little use. He said that more attainable limits must be created. Meanwhile, clinicians should collect clinical data more thoroughly.

In parallel, studies have also raised questions about the role of biologics in the emergence of EGPA.
 

Defining Clinical Remission in Asthma

Last year, a working group, including members from the American Thoracic Society and the American College and Academy of Allergy, Asthma, and Immunology, proposed new guidelines to define clinical remission in asthma. These guidelines extended beyond the typical outcomes of no severe exacerbations, no maintenance oral corticosteroid use, good asthma control, and stable lung function. The additional recommendations included no missed work or school due to asthma, limited use of rescue medication (no more than once a month), and reduced inhaled corticosteroid use to low or medium doses.

To explore the feasibility of achieving these clinical remission outcomes, GSK partnered with the Mayo Clinic for a retrospective analysis of the medical records of 700 patients with asthma undergoing various biologic therapies. The study revealed that essential data for determining clinical remission, such as asthma control and exacerbation records, were inconsistently documented. While some data were recorded, such as maintenance corticosteroid use in 50%-60% of cases, other key measures, like asthma control, were recorded in less than a quarter of the patients.

GSK researchers analyzed available data and found that around 30% of patients on any biologic therapy met three components of remission. Mepolizumab performed better than other corticosteroids, with over 40% of those receiving the drug meeting these criteria. However, when stricter definitions were applied, such as requiring four or more remission components, fewer patients achieved remission — less than 10% for four components, with no patients meeting the full seven-point criteria proposed by the working group.

An ongoing ERS Task Force is now exploring what clinical remission outcomes are practical to achieve, as the current definitions may be too aspirational, said Mr. Howarth. “It’s a matter of defying what is practical to achieve because if you can’t achieve it, then it won’t be valuable.”

He also pointed out that biologics are often used for the most severe cases of asthma after other treatments have failed. Evidence suggests that introducing biologics earlier in the disease, before chronic damage occurs, may result in better patient outcomes.
 

Biologics and EGPA

In a retrospective study, clinical details of 27 patients with adult-onset asthma from 28 countries, all on biologic therapy, were analyzed. The study, a multicounty collaboration, was led by ERS Severe Heterogeneous Asthma Research Collaboration, Patient-centred (SHARP), and aimed to understand the role of biologics in the emergence of EGPA.

The most significant finding presented at the ERS 2024 International Congress was that EGPA was not associated with maintenance corticosteroids; instead, it often emerged when corticosteroid doses were reduced or tapered off. “This might suggest that steroid withdrawal may unmask the underlying disease,” said Hitasha Rupani, MD, a consultant respiratory physician at the University Hospital Southampton, in Southampton, England. Importantly, the rate at which steroids were tapered did not influence the onset of EGPA, indicating that the tapering process, rather than its speed, may be the critical factor. However, due to the small sample size, this remains a hypothesis, Dr. Rupani explained.

The study also found that when clinicians had a clinical suspicion of EGPA before starting biologic therapy, the diagnosis was made earlier than in cases without such suspicion. Dr. Rupani concluded that this underscores the importance of clinical vigilance and the need to monitor patients closely for EGPA symptoms, especially during corticosteroid tapering.

The study was funded by GSK. Mr. Howarth is an employee at GSK. Dr. Rupani reports no relevant financial relationships.

TOPLINE:

Exposure to environmental particulate matter ≤ 10 μm in diameter (PM₁₀) is associated with an increased risk for giant cell arteritis, particularly in older individuals aged ≥ 70 years and those with prolonged exposure to high levels of air pollution.

METHODOLOGY:

• Researchers conducted a retrospective case-crossover study to examine the association between exposure to airborne PM₁₀ and the risk for giant cell arteritis and its ischemic complications.
• They included 232 patients with giant cell arteritis (median age at diagnosis, 73 years; 69% women) from three hospitals in northern Italy between June 2013 to December 2021.
• The hourly and daily average concentrations of PM₁₀ were collected from the Italian monitoring network; patients’ exposure to PM₁₀ was calculated using a space-time statistical model, incorporating meteorological variables, elevation, and proximity to main roads.
• The mean follow-up time of this cohort was 38 months.

TAKEAWAY:

• Every 10 μg/m³ increase in PM₁₀ exposure in the preceding 60 days increased the incremental risk (IR) for giant cell arteritis by 27.1% (95% CI, 5.8-52.6).
• This association was more pronounced (IR, 38.8%; 95% CI, 9.2-76.3) in the subgroup of patients aged ≥ 70 years.
• The positive association between incident giant cell arteritis and concentrations of PM₁₀ was seen only when patients were exposed to high concentrations of PM₁₀ (26.9 ± 13.8 μg/m³) but not low concentrations (11.9 ± 7.9 μg/m³).
• This study did not show any significant association between exposure to PM₁₀ and ischemic complications.

IN PRACTICE:

“Exposure to PM₁₀ in the 60 days preceding [giant cell arteritis] symptoms onset seems to be associated with an increased risk of developing the disease, especially in older individuals with prolonged exposure to high levels of air pollution,” the authors wrote.

SOURCE:

The study was led by Milena Bond, MD, Hospital of Bruneck, Teaching Hospital of the Paracelsus Medical University, Brunico, Italy, and was published online in Arthritis Care & Research.

LIMITATIONS:

The retrospective nature of the study may have introduced recall bias. The study did not include data for other particulate matter fractions or gaseous pollutants, which may have impacted the findings. The use of residential addresses at the time of diagnosis precluded assessment of potential recent relocations.

DISCLOSURES:

This study did not disclose any funding source. Some authors reported having financial relationships with multiple pharmaceutical companies.

New treatment strategies in clinical trials show promise in reducing the tapering time of glucocorticoids (GCs) or possibly even replacing the use of GCs. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.

“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.

GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.

HSD-1 Inhibitors Under Study

11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.

Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.

GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.

During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.

A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.

“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.

An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.

Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone. They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.

In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
 

Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate

A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.

A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.

ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.

A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.

“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.
 

C5a and Interleukin (IL)-6 Receptor Inhibitors as GC-Sparing Drugs

Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.

A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.

Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.

Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.

Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.

Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.

In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.

Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.

A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.

Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.

Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.

Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.

Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.

In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.

New treatment strategies in clinical trials show promise in reducing the tapering time of glucocorticoids (GCs) or possibly even replacing the use of GCs. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.

“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.

GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.

HSD-1 Inhibitors Under Study

11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.

Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.

GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.

During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.

A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.

“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.

An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.

Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone. They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.

In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
 

Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate

A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.

A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.

ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.

A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.

“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.

VIENNA — Results from the phase 3 SELECT-GCA study showed that the Janus kinase (JAK) inhibitor upadacitinib (Rinvoq) induces significant and sustained remission in people with new-onset or relapsing giant cell arteritis (GCA).

The primary endpoint of sustained remission — the absence of GCA signs or symptoms from weeks 12 to 52 together with adherence to a steroid-tapering regimen — occurred in 46% of 210 individuals randomly assigned to treatment treated with a once-daily 15-mg dose of upadacitinib and 29% of 105 randomly assigned to placebo (P = .0019).

Nine of the 11 secondary endpoints were also positive for upadacitinib 15 mg vs placebo, and no new safety concerns were identified in a late-breaking abstract presented at the at the annual European Congress of Rheumatology.
 

First JAK Trial in GCA

This is the first trial to look at the use of a JAK inhibitor for the treatment of GCA, and it is addressing a real unmet need, the presenting study investigator Daniel Blockmans, MD, PhD, of University Hospitals Leuven in Belgium, told this news organization.

Glucocorticoids remain the mainstay of treatment, and tocilizumab has been licensed for use, but people don’t always get better or can relapse, he explained.

“I have the impression that these only suppress the disease but do not cure it,” Dr. Blockmans said, adding that “patients get very well soon after these treatments are started, but there are more and more reports that there is a kind of smoldering vasculitis that exists, and this can lead to dilatation of the aorta.”

Upadacitinib inhibits two JAK-dependent cytokines, interleukin 6 and interferon gamma, which have been implicated in the pathogenesis of GCA. The latter could be particularly important, Dr. Blockmans suggested.
 

Study Details

SELECT-GCA is an ongoing multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of upadacitinib vs placebo in patients with GCA.

A total of 428 patients have been included: 210 were randomly allocated to treatment with upadacitinib 15 mg, 105 to upadacitinib 7.5 mg, and 105 to placebo. The inclusion of the lower “minimally effective” upadacitinib dose was a requirement of the regulatory authorities, Dr. Blockmans said; the licensed dose in rheumatoid arthritis (RA) is 15 mg.

Dr. Blockmans reported data from the first 52 weeks of the trial during which all patients underwent glucocorticoid tapering — 26 weeks for upadacitinib and 52 weeks for placebo.

No imaging was done in this trial, which Dr. Blockmans said should be considered for future studies.
 

Secondary Endpoints

One of the key secondary endpoints was sustained complete remission, defined as sustained remission plus a normalized erythrocyte sedimentation rate to ≤ 30 mm/h and reducing high-sensitivity C-reactive protein to < 1 mg/dL.

Sustained complete remission occurred in 37% and 16% of patients treated with upadacitinib 15 mg and placebo, respectively (P < .0001).

Additionally, a significantly lower proportion of upadacitinib 15 mg- than placebo-treated patients experienced at least one disease flare through week 52 (34% vs 56%, P = .0014).

Other positive secondary endpoints for upadacitinib 15 mg vs placebo out to week 52 were the number of disease flares per patient, cumulative glucocorticoid exposure, and complete remission (also at week 24).

And significant changes in SF-36 and FACIT-Fatigue from baseline to week 52 were seen for upadacitinib 15 mg.

The only secondary endpoints not showing a clear benefit for upadacitinib 15 mg were the changes in the Treatment Satisfaction Questionnaire for Medication at 52 weeks and the rate of glucocorticoid-related adverse events through week 52.

As for the 7.5-mg dose of upadacitinib, neither the primary nor secondary endpoints were significantly better vs placebo.
 

‘Life-Changing’

The study’s findings could be “really life-changing” for patients with this type of vasculitis if upadacitinib gets approval for use in this indication, Milena Bond, MD, PhD, of Brunico Hospital in Italy, told this news organization at the meeting.

“Unfortunately, nowadays, we still have only a few options for treating these patients,” she said. “So, this drug could be really, really important.”

Dr. Bond added: “The data ... also shows there is a very good safety profile, which was a main concern given the class of the drug. So, I’m very positive about this treatment and very excited to see the preliminary results.”

After his presentation, Dr. Blockmans said, “Of course, if we already had an ideal treatment for GCA, there would be no need for a JAK inhibitor, but I don’t think that steroid treatment or tocilizumab treatment is the ideal treatment.”
 

Judicious Use Still Warranted

Upadacitinib still needs to be used cautiously, following appropriate guidance from the European Medicines Agency (EMA) and the US Food and Drug Administration.

Dr. Bond said: “It is not advised to use to the drug when people are older than 65 years old,” according to the EMA, for example, and “given the rules that we have, I would not use this drug as a first-line treatment. We do not do that for rheumatoid arthritis.”

But, she added, “As for arthritis, when you fail treating patients with the other alternatives, you could use this drug, and you have to discuss risks with the patients.”

Dr. Blockmans reported there had been no increased risk for major adverse cardiovascular events or venous thromboembolism associated with upadacitinib relative to placebo in the population of patients studied, and he pointed out that they had a much higher risk for these events than perhaps an RA population.

He said: “It’s effective, and it’s apparently safe in these older people, despite what we heard about tofacitinib in the ORAL [Surveillance] study; we didn’t see these problems here in this elderly population.”

The SELECT-GCA trial was funded by AbbVie, and the company participated in all aspects of the study, including its design, conduct, interpretation of data, and reporting. Dr. Blockmans received no funding or other honoraria from the company but reported a research grant from Roche and consulting fees from GlaxoSmithKline. Most of his coauthors reported financial relationships with AbbVie, and some are employees of the company. Dr. Bond reported no relevant financial relationships.

Temporal artery ultrasound alone was sufficient to accurately diagnose giant cell arteritis (GCA) in over half of patients in a new prospective study.

The findings provide further evidence that “[ultrasound] of temporal arteries could really take the place of traditional temporal artery biopsy (TAB)” in patients with high clinical suspicion of GCA, lead author Guillaume Denis, MD, of the Centre Hospitalier de Rochefort in Rochefort, France, told this news organization.

The European Alliance of Associations for Rheumatology (EULAR) already recommends ultrasound as a first-line diagnostic tool for patients with suspected large vessel vasculitis, and the 2022 American College of Rheumatology (ACR)/EULAR classification criteria for GCA weighs positive TAB or temporal artery halo sign on ultrasound equally.

Methodology

In the study, researchers recruited 165 individuals with high clinical suspicion of GCA from August 2016 through February 2020 at six French hospitals. Only patients older than 50 years of age and with biologic inflammatory syndrome with C-reactive protein elevation (≥ 6 mg/L) qualified for the study. Patients also needed to have at least one of these factors:

• Clinical signs of GCA (abnormal temporal arteries, scalp hyperesthesia, jaw claudication, or vision loss)
• General signs of GCA (headache, fever, or impaired general condition)
• Large-vessel vasculitis visible on imaging (CT angiography [CTA], MR angiography [MRA], and/or PET/CT)

All participants underwent a color Doppler ultrasound of the temporal artery, performed less than 1 week after the initiation of corticosteroid therapy. (Previous research demonstrated that corticosteroids can change the hallmark halo sign of vasculitis detectable via ultrasound as early as 1 week after initiation of therapy, the authors noted.) In this study, the time between consultation with a specialist and ultrasound was less than 1 day.

“Patients with halo signs detected around the lumen of both temporal arteries (that is, bilateral temporal halo sign) were considered as ultrasound-positive,” Guillaume Denis, MD, and colleagues explained. “Patients with no halo sign, or bilateral halo signs in the axillary arteries, or a unilateral halo sign in the temporal artery were considered as ultrasound-negative.”

The findings were published in Annals of Internal Medicine on May 7.
 

Results

In total, 73 participants (44%) had positive ultrasounds and were diagnosed with GCA. These patients also underwent a second ultrasound a month later to document if the halo sign remained unchanged, reduced, or disappeared.

The remaining 92 patients with negative ultrasound results underwent TAB, which was conducted on average 4.5 days after the ultrasound. A total of 28 patients (30%) had a positive TAB result. Physicians diagnosed 35 TAB-negative patients with GCA using clinical, imaging, and biologic data, and 29 patients received alternative diagnoses. These other diagnoses included polymyalgia rheumatica, infectious diseases, cancer, and other systemic inflammatory rheumatic diseases.

All patients diagnosed with GCA via ultrasound had their diagnoses reconfirmed at 1 month and for up to 2 years of follow-up.

“In summary, our study showed that the use of temporal artery ultrasound may be an efficient way to make the diagnosis of GCA in patients with high clinical suspicion and to reduce imaging costs and the need for biopsy, thereby limiting complications and the need for a surgeon,” the authors concluded.
 

Qualifications and Limitations

While over half of patients ultimately diagnosed with GCA were diagnosed using ultrasound, that percentage was “a bit lower than expected,” said Mark Matza, MD, MBA, the co-clinical director of rheumatology at Massachusetts General Hospital in Boston. By comparison, one systematic review calculated ultrasound’s pooled sensitivity at 88% and pooled specificity at 96% for the diagnosis of GCA.

“In this [current] study, 30% of patients who had negative ultrasound were then found to have positive biopsy, indicating that ultrasound missed a substantial portion of patients who were ultimately diagnosed with GCA,” he continued.

Ultrasound is “very operator dependent,” he added, and there has been “variability in test performance of ultrasound.”

The authors acknowledged that techniques for ultrasound of the temporal arteries have also evolved over the study period, and thus, findings may not have been consistent.

However, about one in four patients with GCA were diagnosed after having both negative ultrasound and TAB results.

“One of the things that this paper shows is that even the gold standard of temporal artery biopsy isn’t 100% either,” noted Minna Kohler, MD, who directs the rheumatology musculoskeletal ultrasound program at Massachusetts General Hospital. “That’s why clinically, there is an increasing emphasis on using multimodality imaging to assist in the diagnosis of GCA along with a physician’s clinical intuition,” she said.

Temporal artery ultrasound alone was sufficient to accurately diagnose giant cell arteritis (GCA) in over half of patients in a new prospective study.

The findings provide further evidence that “[ultrasound] of temporal arteries could really take the place of traditional temporal artery biopsy (TAB)” in patients with high clinical suspicion of GCA, lead author Guillaume Denis, MD, of the Centre Hospitalier de Rochefort in Rochefort, France, told this news organization.

The European Alliance of Associations for Rheumatology (EULAR) already recommends ultrasound as a first-line diagnostic tool for patients with suspected large vessel vasculitis, and the 2022 American College of Rheumatology (ACR)/EULAR classification criteria for GCA weighs positive TAB or temporal artery halo sign on ultrasound equally.

Methodology

In the study, researchers recruited 165 individuals with high clinical suspicion of GCA from August 2016 through February 2020 at six French hospitals. Only patients older than 50 years of age and with biologic inflammatory syndrome with C-reactive protein elevation (≥ 6 mg/L) qualified for the study. Patients also needed to have at least one of these factors:

• Clinical signs of GCA (abnormal temporal arteries, scalp hyperesthesia, jaw claudication, or vision loss)
• General signs of GCA (headache, fever, or impaired general condition)
• Large-vessel vasculitis visible on imaging (CT angiography [CTA], MR angiography [MRA], and/or PET/CT)

All participants underwent a color Doppler ultrasound of the temporal artery, performed less than 1 week after the initiation of corticosteroid therapy. (Previous research demonstrated that corticosteroids can change the hallmark halo sign of vasculitis detectable via ultrasound as early as 1 week after initiation of therapy, the authors noted.) In this study, the time between consultation with a specialist and ultrasound was less than 1 day.

“Patients with halo signs detected around the lumen of both temporal arteries (that is, bilateral temporal halo sign) were considered as ultrasound-positive,” Guillaume Denis, MD, and colleagues explained. “Patients with no halo sign, or bilateral halo signs in the axillary arteries, or a unilateral halo sign in the temporal artery were considered as ultrasound-negative.”

The findings were published in Annals of Internal Medicine on May 7.
 

Results

In total, 73 participants (44%) had positive ultrasounds and were diagnosed with GCA. These patients also underwent a second ultrasound a month later to document if the halo sign remained unchanged, reduced, or disappeared.

The remaining 92 patients with negative ultrasound results underwent TAB, which was conducted on average 4.5 days after the ultrasound. A total of 28 patients (30%) had a positive TAB result. Physicians diagnosed 35 TAB-negative patients with GCA using clinical, imaging, and biologic data, and 29 patients received alternative diagnoses. These other diagnoses included polymyalgia rheumatica, infectious diseases, cancer, and other systemic inflammatory rheumatic diseases.

All patients diagnosed with GCA via ultrasound had their diagnoses reconfirmed at 1 month and for up to 2 years of follow-up.

“In summary, our study showed that the use of temporal artery ultrasound may be an efficient way to make the diagnosis of GCA in patients with high clinical suspicion and to reduce imaging costs and the need for biopsy, thereby limiting complications and the need for a surgeon,” the authors concluded.
 

Qualifications and Limitations

While over half of patients ultimately diagnosed with GCA were diagnosed using ultrasound, that percentage was “a bit lower than expected,” said Mark Matza, MD, MBA, the co-clinical director of rheumatology at Massachusetts General Hospital in Boston. By comparison, one systematic review calculated ultrasound’s pooled sensitivity at 88% and pooled specificity at 96% for the diagnosis of GCA.

“In this [current] study, 30% of patients who had negative ultrasound were then found to have positive biopsy, indicating that ultrasound missed a substantial portion of patients who were ultimately diagnosed with GCA,” he continued.

Ultrasound is “very operator dependent,” he added, and there has been “variability in test performance of ultrasound.”

LIVERPOOL, ENGLAND — The British Society for Rheumatology (BSR) and the British Association of Dermatologists (BAD) have joined forces for the first time to develop the first British guidelines for the management of people living with Behçet’s disease.

The guidelines will also be the first “living guidelines” produced by either society, which means they will be regularly revised and updated when new evidence emerges that warrants inclusion.

With more than 90 recommendations being made, the new guidelines promise to be the most comprehensive and most up-to-date yet for what is regarded as a rare disease. Robert Moots, MBBS, PhD, provided a “sneak peek” of the guidelines at the annual meeting of the British Society for Rheumatology.

Dr. Moots, professor of rheumatology at the University of Liverpool and a consultant rheumatologist for Liverpool University Hospitals NHS Foundation Trust in England, noted that while the European Alliance of Associations for Rheumatology has produced a guideline for Behçet’s disease, this was last updated in 2018 and is not specific for the population for patients that is seen in the United Kingdom.

The British recommendations will cover all possible manifestations of Behçet’s disease and give practical advice on how to manage everything from the most common presentations such as skin lesions, mouth ulcers, and genital ulcers, as well as the potentially more serious eye, neurological, and vascular involvement.

Importance of Raising Awareness

“Joint and musculoskeletal problems are actually one of the least complained of symptoms in people with Behçet’s, and they often can’t understand why a rheumatologist is seeing them,” Dr. Moot said. “But of course, people do get joint problems, they can get enthesitis and arthralgia.”

Dr. Moots has been leading one of the three National Health Service (NHS) Centres of Excellence for Behçet’s Syndrome in England for more than a decade and told this news organization that diagnosing patients could be challenging. It can take up to 10 years from the first symptoms appearing to getting a diagnosis, so part of the job of the NHS Centres of Excellence is to raise awareness among both the healthcare profession and the general public.

“It’s a condition that people learn about at medical school. Most doctors will have come across it, but because it was thought to be really rare in the UK, nobody perhaps really expects to see it,” Dr. Moot said.

“But we all have these patients,” he added. “In Liverpool, we’re commissioned to be looking after an anticipated 150 people with Behçet’s — we’ve got 700. With more awareness, there’s more diagnoses being made, and people are being looked after better.”
 

Patient Perspective

Tony Thornburn, OBE, chair of the patient advocacy group Behçet’s UK, agreed in a separate interview that raising awareness of the syndrome was key to improving its management.

“Patients have said that it is a bit like having arthritis, lupus, MS [multiple sclerosis], and Crohn’s [disease] all at once,” Mr. Thorburn said. “So what we need is a guideline to ensure that people know what they’re looking at.”

Mr. Thorburn added, “Guidelines are important for raising awareness but also providing the detailed information that clinicians and GPs [general practitioners] need to have to treat a patient when they come in with this multifaceted condition.”
 

Multifaceted Means Multidisciplinary Management

Because there can be so many different aspects to managing someone with Behçet’s disease, a multispecialty team that was convened to develop the guidelines agreed that multidisciplinary management should be an overarching theme.

“The guideline development group consisted of all the specialties that you would need for a complex multisystem disease like Behçet’s,” Dr. Moot said. He highlighted that working alongside the consultants in adult and pediatric rheumatology were specialists in dermatology, gastroenterology, neurology, ophthalmology, obstetrics and gynecology, and psychology.

“We’re actually looking at psychological interactions and their impact for the first time,” Dr. Moot said, noting that clinicians needed to “take it seriously, and ask about it.”
 

Management of Manifestations

One of the general principles of the guidelines is to assess the involvement of each organ system and target treatment accordingly.

“One of the problems is that the evidence base to tell us what to do is pretty low,” Dr. Moots acknowledged. There have been few good quality randomized trials, so “treatment tends to be eminence-based rather than evidence-based.”

The recommendation wording bears this in mind, stating whether a treatment should or should not be offered, or just considered if there is no strong evidence to back up its use.

With regard to musculoskeletal manifestations, the recommendations say that colchicine should be offered, perhaps as a first-line option, or an intraarticular steroid injection in the case of monoarthritis. An intramuscular depot steroid may also be appropriate to offer, and there was good evidence to offer azathioprine or, as an alternative in refractory cases, a tumor necrosis factor (TNF) inhibitor. Nonsteroidal anti-inflammatory drugs, methotrexate, apremilast, secukinumab, and referral to a physiotherapist could only be considered, however, based on weaker levels of evidence for their use.

To treat mucocutaneous disease, the guidelines advise offering topical steroids in the form of ointment for genital ulcers or mouthwash or ointment for oral ulcers. For skin lesions, it is recommended to offer colchicine, azathioprine, mycophenolate mofetil, or TNF inhibitor and to consider the use of apremilast, secukinumab, or dapsone.
 

Future Work and Revision

“One of the key things we would like to see developing is a national registry,” Dr. Moots said. This would include biobanking samples for future research and possible genomic and phenotyping studies.

More work needs to be done in conducting clinical trials in children and young people with Behçet’s disease, studies to find prognostic factors for neurological disease, and clinical trials of potential new drug approaches such as Janus kinase inhibitors. Importantly, an auditing process needs to be set up to see what effect, if any, the guidelines will actually have onpatient management.

“It’s taken 5 years to today” to develop the guidelines, Dr. Moot said. What form the process of updating them will take still has to be decided, he said in the interview. It is likely that the necessary literature searches will be performed every 6 months or so, but it will be a compromise between the ideal situation and having the staffing time to do it.

“It’s a big ask,” Dr. Moot acknowledged, adding that even if updates were only once a year, it would still be much faster than the 5- or 6-year cycle that it traditionally takes for most guidelines to be updated.

The BSR and BAD’s processes for developing guidelines are accredited by the National Institute for Health and Care Excellence in England. Dr. Moots is the chief investigator for the Secukinumab in Behçet’s trial, which is sponsored by the Liverpool University Hospitals NHS Foundation Trust via grant funding from Novartis.

Patients with granulomatosis with polyangiitis (GPA) who scored high on a sinonasal symptom test are nearly three times as likely to relapse, according to a new study.

These patients reported higher scores months and up to 2 years before a disease flare, despite having low disease activity otherwise.

The study uses a different approach to try to predict relapse, compared with measuring biomarkers in lab tests, said Zachary Wallace, MD, a rheumatologist at Massachusetts General Hospital in Boston, Massachusetts. He was not involved with the study.

“It’s exciting because it might suggest that we could use something as simple as a survey to stratify someone’s risk of relapse,” he told this news organization.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare disease, with an estimated prevalence of 200-400 cases per million people. It is also heterogeneous, which makes it difficult to predict the risk for relapse for a given patient.

“Investigators have long searched for a reliable prognostic marker that identifies patients at high vs low risk of relapse in AAV but, except for ANCA type, no prognostic biomarker is routinely used to inform treatment decision-making,” wrote lead author Ellen Romich, MD, a rheumatology fellow at the University of Pennsylvania in Philadelphia, Pennsylvania, and colleagues.

Proteinase 3-ANCA (compared with myeloperoxidase-ANCA) has been tied to a higher risk for relapse, as well as gastrointestinal complications, sinonasal disease, and patient global assessment scores. In this new study, Dr. Romich and colleagues evaluated if patient-reported outcomes of sinonasal disease could predict AAV disease activity and relapse.

Researchers used data from a prospective, longitudinal cohort study through the University of Pennsylvania Vasculitis Center from 2016 to 2022. They included 107 patients with GPA, 40 patients with eosinophilic granulomatosis with polyangiitis (EGPA), 21 patients with microscopic polyangiitis (MPA), and 51 healthy controls.

Patients completed a median of four clinic visits during the duration of the study.

During each visit, patients filled out the 22-item SinoNasal Outcome Test (SNOT-22), a validated questionnaire that assesses rhinosinusitis. The tool asks patients to rate a list of symptoms from 0 to 5 in five categories: Rhinologic, extra-nasal, ear and face, psychologic, and sleep. The possible total score ranges from 0 to 110.

Disease activity was measured via the Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis. The results were published online in Arthritis Care & Research.

Patients were, on average, 55 years old with an AAV duration of 3 years. (The mean age of healthy participants was 59.) More than half (58%) of patients were female, and 95% were White. The majority had a history of a flare (54%), and 60% of those flares had sinonasal involvement.

Even in remission, patients with AAV generally had on average higher SNOT-22 scores than healthy comparators (20 vs 5). Higher disease activity also correlated with higher SNOT-22 scores.

In patients with GPA, a high SNOT-22 score (total score of 41 or above) was associated with an increased risk for relapse within 2 years (hazard ratio, 2.7; P = .02). This association was not found for EGPA or MPA. This higher risk remained in a sensitivity analysis that included only patients with no history of sinonasal disease.

“Interestingly, among patients with GPA, SNOT-22 scores are elevated months to years prior to onset of systemic relapse but remain low in patients in sustained remission,” the authors wrote.

While other patient-reported outcomes have been validated for AAV, SNOT-22 may provide more detail on upper airway disease, commented Paul Monach, MD, PhD, an adjunct associate professor of medicine at the Boston University Chobanian & Avedisian School of Medicine and a rheumatologist at the VA Boston Healthcare System, Boston, Massachusetts.

“Upper airway GPA has not been studied as much as systemic GPA and MPA,” he told this news organization. “There are very few clinical trials, and we need better outcome measures like this.”

Dr. Romich noted that this work is still in the “early stages,” and SNOT-22 will need to be further studied and validated in other patient cohorts before its inclusion in clinical practice.

“There’s certainly more work that needs to be done to understand how the SNOT-22 questionnaire works in this patient population,” she said, including its predictive value compared with other known risk factors for relapse. “But I think it’s something that’s promising that we could use as a patient-reported outcome to try to, visit-to-visit, track their sinonasal symptoms.”

Patients with granulomatosis with polyangiitis (GPA) who scored high on a sinonasal symptom test are nearly three times as likely to relapse, according to a new study.

These patients reported higher scores months and up to 2 years before a disease flare, despite having low disease activity otherwise.

The study uses a different approach to try to predict relapse, compared with measuring biomarkers in lab tests, said Zachary Wallace, MD, a rheumatologist at Massachusetts General Hospital in Boston, Massachusetts. He was not involved with the study.

“It’s exciting because it might suggest that we could use something as simple as a survey to stratify someone’s risk of relapse,” he told this news organization.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare disease, with an estimated prevalence of 200-400 cases per million people. It is also heterogeneous, which makes it difficult to predict the risk for relapse for a given patient.

“Investigators have long searched for a reliable prognostic marker that identifies patients at high vs low risk of relapse in AAV but, except for ANCA type, no prognostic biomarker is routinely used to inform treatment decision-making,” wrote lead author Ellen Romich, MD, a rheumatology fellow at the University of Pennsylvania in Philadelphia, Pennsylvania, and colleagues.

Proteinase 3-ANCA (compared with myeloperoxidase-ANCA) has been tied to a higher risk for relapse, as well as gastrointestinal complications, sinonasal disease, and patient global assessment scores. In this new study, Dr. Romich and colleagues evaluated if patient-reported outcomes of sinonasal disease could predict AAV disease activity and relapse.

Researchers used data from a prospective, longitudinal cohort study through the University of Pennsylvania Vasculitis Center from 2016 to 2022. They included 107 patients with GPA, 40 patients with eosinophilic granulomatosis with polyangiitis (EGPA), 21 patients with microscopic polyangiitis (MPA), and 51 healthy controls.

Patients completed a median of four clinic visits during the duration of the study.

During each visit, patients filled out the 22-item SinoNasal Outcome Test (SNOT-22), a validated questionnaire that assesses rhinosinusitis. The tool asks patients to rate a list of symptoms from 0 to 5 in five categories: Rhinologic, extra-nasal, ear and face, psychologic, and sleep. The possible total score ranges from 0 to 110.

Disease activity was measured via the Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis. The results were published online in Arthritis Care & Research.

Patients were, on average, 55 years old with an AAV duration of 3 years. (The mean age of healthy participants was 59.) More than half (58%) of patients were female, and 95% were White. The majority had a history of a flare (54%), and 60% of those flares had sinonasal involvement.

Even in remission, patients with AAV generally had on average higher SNOT-22 scores than healthy comparators (20 vs 5). Higher disease activity also correlated with higher SNOT-22 scores.

In patients with GPA, a high SNOT-22 score (total score of 41 or above) was associated with an increased risk for relapse within 2 years (hazard ratio, 2.7; P = .02). This association was not found for EGPA or MPA. This higher risk remained in a sensitivity analysis that included only patients with no history of sinonasal disease.

Some of the best clinical trials of patients with antineutrophil cytoplasmic antibody–associated vasculitis (AAV) that were presented at the 21st International Vasculitis Workshop in Barcelona, Spain, included studies addressing relapse after stopping steroids, preventing relapse with abatacept, improving kidney function with plasma exchange, and vaccinating rituximab-treated patients.
 

Stopping Steroids After Remission in GPA

In the randomized, open-label TAPIR (The Assessment of Prednisone In Remission Trial) study of 159 adults with GPA in remission who had tapered to a prednisone dose of 5 mg/day, those who remained at that dosage had a significantly lower rate of relapse after 6 months than those who tapered to 0 mg/day (4.2% vs 15.5%; P = .227), according to results reported at the meeting.

However, use of a higher dose of prednisone for disease relapse by 6 months was similar for patients who used rituximab at baseline (8.8% with 0 mg/day vs 6.1% with 5 mg/day; P = .667), and the difference in this primary outcome was more pronounced among patients who did not take rituximab at baseline (20.0% with 0 mg/day vs 2.6% with 5 mg/day; P = .023).

A higher percentage of patients taking prednisone 0 mg/day had disease relapses that were considered minor (14.1% and 4.2%; P = .0391). Major relapses occurred in none of the patients taking 5 mg/day and in 1.4% receiving 0 mg/day. About 90% of patients in either treatment arm completed the trial.

The study, funded by the National Institute of Arthritis and Musculoskelatal and Skin Diseases and the National Heart Lung and Blood Institute, was unique in that half of patients randomized in the study were enrolled at community clinics and half were enrolled at Vasculitis Clinical Research Consortium clinical centers.
 

Abatacept Falls Short for Preventing Relapse in GPA

Adding abatacept to glucocorticoids failed to reduce risk of relapse, worsening disease, or failure to reach remission in adults with relapsing, nonsevere GPA, based on data from a randomized trial of 65 individuals.

In the 20-site, randomized, double-blind ABROGATE (Abatacept for the Treatment of Relapsing, Non-Severe, Granulomatosis With Polyangiitis) study, 34 patients received 125 mg subcutaneous abatacept once a week or a placebo in addition to 30 mg/day of prednisone that was tapered and discontinued after 12 weeks. Patients who were receiving methotrexate, azathioprine, mycophenolate, or leflunomide at baseline continued the medication at a stable dose.

The primary outcome of disease worsening or relapse occurred in 62% of the abatacept group and 68% of the placebo group, and no significant difference in treatment failure rate appeared between the groups. In addition, key secondary endpoints of time to full remission, duration of glucocorticoid-free remission, relapse severity, prevention of damage, and patient-reported quality of life outcomes were not significantly different between the groups.

A total of 112 adverse events occurred, with similar type and severity between the groups, including incidence of infections.

The findings were limited by the relatively small sample size, but the results suggest a need for further research to determine mechanisms of disease and explore additional novel treatments for this rare patient population, the researchers wrote in their abstract.

The study was funded by the National Institutes of Health and Bristol-Myers Squibb.
 

Plasma Exchange Improves Kidney Function in AAV

Use of therapeutic plasma exchange (PLEX) as an adjunct treatment improved early kidney function in adults with AAV and glomerulonephritis but did not extend beyond 8 weeks, and recovery of kidney function was no different between patients receiving a regular glucocorticoid regimen versus a reduced course, based on a post-hoc analysis of 691 individuals in the international randomized controlled trial called PEXIVAS.

The primary outcomes of change in kidney function based on estimated glomerular filtration rate (eGFR) from baseline over 1 year and the percentage of patients with improvement in eGFR of at least 15 mL/min/1.73 m² at weeks 12, 26, and 52.

The rate of improved eGFR was significantly greater in the PLEX group, compared with controls, at 2, 4, and 8 weeks. At 4 weeks, significantly more patients in the PLEX group had an increase in eGFR by at least 15 mL/min/1.73 m², compared with the control group (relative risk [RR], 1.41; P = .008). In addition, improved kidney function within 4 weeks was significantly associated with lower risk of kidney failure within 1 year, regardless of treatment group.

The original PEXIVAS trial was supported by various government institutes and agencies from multiple countries.
 

Reinforced Vaccine Strategy with Rituximab Improved Antibody Response in AAV

A vaccine strategy consisting of a double dose of 13-valent antipneumococcal conjugate vaccine (PCV13) at day 0 and day 7 followed by a single dose of 23-valent unconjugated pneumococcal polysaccharide vaccine (PPV23) at 5 months significantly improved antibody responses against Streptococcus pneumoniae in patients with AAV, compared with standard treatment, based on data from 95 individuals in the multicenter, open-label study called PNEUMOVAS.

Adults with newly diagnosed AAV were randomly assigned to one of three treatment arms: a standard regimen of one dose of PCV13 at day 0 and one dose of PPV23 at month 5 (arm 1); a double dose of PCV13 at day 0 and day 7 with a dose of PPV23 at month 5 (arm 2); or four doses of PCV13 at day 0 and one dose of PPV23 at month 5 (arm 3). These patients received PCV13 within 2 days before or after their first infusion of rituximab.

The primary endpoint was positive antibody response against 12 pneumococcal subtypes common to the PCV13 and PCV23 vaccines at 6 months. At 6 months, the immune response to 0-3, 4-6, 7-9, or 10-12 serotypes was 83.3%, 13.3%, 3.3%, and 0%, respectively, in arm 1; 56.3%, 28.1%, 15.6%, and 0% in arm 2; and 60.6%, 33.3%, 6.1%, and 0% in arm 3.

No severe adverse events related to vaccination were observed in any of the groups; a total of eight AAV flares occurred in six patients (one in arm 1, two in arm 2, and three in arm 3). Local and systemic reactions occurred more frequently with the reinforced dose regimens, but these were mostly grade 1 or 2 local reactions.

The study was supported by the French Ministry of Health.

TOPLINE:

Age older than 65 years and serum creatinine greater than 140 micromol/L at the time of systemic polyarteritis nodosa (PAN) diagnosis were significant predictors of mortality.

METHODOLOGY:

• A total of 358 patients diagnosed with PAN between 1990 and 2020 were identified from retrospective chart reviews and prospective cohorts from nine countries as a part of GLOBAL-PAN, a collaboration of the European Vasculitis Society, the Vasculitis Clinical Research Consortium, and other networks.
• The goal of the retrospective chart review was to characterize the nature, presentation, and survival rates of patients with PAN.
• The study population included 174 female and 184 male patients; 282 had systemic PAN (sPAN) and 76 had cutaneous PAN (cPAN); the mean age at diagnosis was 44.3 years.

TAKEAWAY:

• Overall survival rates at 1, 5, and 10 years for patients with sPAN were 97.1%, 94.0%, and 89.0%, respectively.
• Significant independent predictors of mortality were age ≥ 65 years at the time of sPAN diagnosis (hazard ratio [HR], 3.85), serum creatinine > 140 micromol/L at the time of diagnosis (HR, 4.93), gastrointestinal involvement (HR, 3.51), and central nervous system involvement (HR, 3.56).
• Constitutional symptoms were significantly more common in patients with sPAN vs cPAN (78.8% vs 44.7%), while patients with cPAN were significantly more likely to be female and have more skin nodules than patients with sPAN.
• Relapse over a median disease duration of 59.6 months was slightly higher for cPAN vs sPAN (38.8% vs 32.1%).

IN PRACTICE:

“This study helps better define the demographic and clinical characteristics of patients with PAN and differentiates sPAN from cPAN,” the researchers wrote.

TOPLINE:

Age older than 65 years and serum creatinine greater than 140 micromol/L at the time of systemic polyarteritis nodosa (PAN) diagnosis were significant predictors of mortality.

METHODOLOGY:

• A total of 358 patients diagnosed with PAN between 1990 and 2020 were identified from retrospective chart reviews and prospective cohorts from nine countries as a part of GLOBAL-PAN, a collaboration of the European Vasculitis Society, the Vasculitis Clinical Research Consortium, and other networks.
• The goal of the retrospective chart review was to characterize the nature, presentation, and survival rates of patients with PAN.
• The study population included 174 female and 184 male patients; 282 had systemic PAN (sPAN) and 76 had cutaneous PAN (cPAN); the mean age at diagnosis was 44.3 years.

TAKEAWAY:

• Overall survival rates at 1, 5, and 10 years for patients with sPAN were 97.1%, 94.0%, and 89.0%, respectively.
• Significant independent predictors of mortality were age ≥ 65 years at the time of sPAN diagnosis (hazard ratio [HR], 3.85), serum creatinine > 140 micromol/L at the time of diagnosis (HR, 4.93), gastrointestinal involvement (HR, 3.51), and central nervous system involvement (HR, 3.56).
• Constitutional symptoms were significantly more common in patients with sPAN vs cPAN (78.8% vs 44.7%), while patients with cPAN were significantly more likely to be female and have more skin nodules than patients with sPAN.
• Relapse over a median disease duration of 59.6 months was slightly higher for cPAN vs sPAN (38.8% vs 32.1%).

IN PRACTICE:

“This study helps better define the demographic and clinical characteristics of patients with PAN and differentiates sPAN from cPAN,” the researchers wrote.

Comorbidities may play a large role in driving poor pregnancy outcomes in pregnant people with certain immune-mediated inflammatory diseases (IMIDs).

In a new study of 12 individual IMIDs, people with rheumatoid arthritis (RA) or inflammatory bowel disease (IBD) did not have signficantly increased risk for preterm birth (PTB) or low birth weight (LBW), compared with people who did not have an IMID, after adjusting for additional chronic conditions and other confounding factors.

The study was published online on February 1 in eClinicalMedicine.

While many studies have explored the relationships between pregnancy outcomes and IMIDs, “the impact of comorbidities on the relation between IMIDs and pregnancy course is insufficiently examined,” the authors wrote. These previous studies also tended to have a small sample size.
 

Pregnancy Outcome Risks Varied Between IMIDs

To remedy this, researchers used electronic health record data from Providence St Joseph Health — a multistate integrated healthcare system — to identify more than 365,000 pregnant people with live births between January 1, 2013, and December 31, 2022. The cohort included more than 5700 people with at least one of 12 IMIDs: Psoriasis, IBD, RA, spondyloarthritis (SpA), multiple sclerosis, systemic lupus erythematosus (SLE), psoriatic arthritis (PsA), antiphospholipid syndrome (APS), Sjögren syndrome (SjS), vasculitis, sarcoidosis, and systemic sclerosis. The study included only live births with a gestational age of 20 weeks or greater.

Researchers compared maternal-fetal health outcomes between the two groups, controlling for comorbidities including diabetes, cardiovascular disease, chronic kidney disease, obesity, and depression. They also accounted for confounding variables including race, age, smoking status, and socioeconomic status.

In total, 83% of people in the IMID group had no immunomodulatory medication prescriptions during their pregnancy. Of the 17% taking medication, 48%-70% continued taking their medication until delivery. Most patients were White, comprising 62.9% of the non-IMID group and 73.1% of the IMID group.

After adjusting for comorbidities, patients with any of the 12 IMIDs had a 10%-20% higher risk for PTB, LBW, small for gestation age (SGA), and cesarean section than did comparators.

But these risks varied between IMIDs. Patients with RA and IBD did not have an increased risk for PTB or LBW. However, when researchers did not control for comorbidities, pregnancy risks were higher and showed statistical significance in these two groups.

“This suggests that for RA and IBD, comorbidities may be a more important factor for adverse outcomes than the underlying autoimmune disease,” senior author Jennifer Hadlock, MD, an associate professor and director of medical data science at the Institute for Systems Biology in Seattle, Washington, said in a video accompanying a press release.

Overall, the analysis found that women with IMIDs were approximately two to three times more likely to have chronic comorbidities than the control group.

Like previous studies, there was a strong association between SLE and APS and poor pregnancy outcomes, even after controlling for confounding factors. Patients with SpA had a 50% increased risk for PTB, while those with SLE and APS had more than a twofold higher risk. Patients with SLE were 90% more likely than comparators to deliver babies with an SGA condition, while RA patients had a 30% higher risk. SLE was the only condition with an increased risk for LBW (relative risk, 3.5). IBD, RA, PsA, SpA, SLE, APS, and SjS were all associated with a higher likelihood of delivery via cesarean section.

“The findings of this study reveal that the associations between IMIDs and adverse pregnancy outcomes are influenced by the specific type of IMIDs and the presence of comorbidities,” the authors wrote.
 

A Large Study, But How Representative Is It?

Asked to comment on the study, Catherine Sims, MD, a rheumatologist at Duke University Medical Center in Durham, North Carolina, noted that the analysis was much larger than many reproductive rheumatology studies, and “their statistics were phenomenal.”

She agreed that “not all autoimmune diseases are created equal when it comes to pregnancy-associated risks.” However, she added that this study’s patient population may not be totally representative of pregnant people with IMIDs or autoimmune diseases.

“We’re making generalizations about autoimmune diseases based on this demographic of White women who are not taking immunosuppression,” she said.

“We know that race and ethnicity play a huge role in pregnancy outcomes, and Black women have higher maternal and fetal morbidity and mortality, which is likely related to systemic racism and biases in the medical system,” she added. “While the study did control for sociodemographic factors, the population studied is not diverse.”

Only 17% of people with IMID in the cohort were on immunosuppressive medication, which could suggest low disease activity in the study population, Dr. Sims said. If the population generally had well-controlled disease, that could have positioned them for better pregnancy outcomes.

The authors noted that their analysis did not have information on IMID disease activity or severity — one of the limitations of the study.

However, the authors argued that the observed low prescription rate during the study may have increased poor pregnancy outcomes.

“Although this reflects real-world care in the population studied, results from this study may show higher risk than might be achieved with recommended care guidelines,” they wrote.

Ultimately, the authors argued that these findings show how co-occurring health conditions can affect pregnancy outcomes in autoimmune diseases, particularly for RA and IBD.

“There is a need to take comorbidities into consideration for guidelines for patients with inflammatory bowel disease and rheumatoid arthritis and when designing future research to investigate maternal health in patients with IMIDs,” they wrote.

The study was funded by the National Institutes of Health. Dr. Sims declared no relevant financial relationships. Dr. Hadlock has received research funding (paid to the institute) from Pfizer, Novartis, Janssen, Bristol-Myers Squibb, and Gilead.
