Although genomic testing is useful when an interstitial lung disease diagnosis is uncertain, the testing results themselves aren’t sufficient to make the diagnosis, Daniel Dilling, MD, FCCP, said in a presentation at the annual meeting of the American College of Chest Physicians, which was held virtually.

The genomic classifier (Envisia, Veracyte) helps differentiate idiopathic pulmonary fibrosis (IPF) by detecting usual interstitial pneumonia (UIP), the hallmark pattern of this interstitial lung disease.

However, UIP is just one piece of the larger diagnostic puzzle, according to Dr. Dilling, professor of medicine in the interstitial lung disease program at Loyola University Medical Center in Maywood, Ill.

“Remember, it’s just a pattern, and not a diagnosis of IPF,” Dr. Dilling said in his presentation.

Genomic classifier results correlate well with both histologic and radiographic UIP pattern, studies show.

However, Dr. Dilling said the value of the genomic classifier is not in isolation.

“We don’t use this in a vacuum,” he said. “It increases our confidence and consensus, but it has to be incorporated into a multidisciplinary discussion group.”
 

Part of the diagnostic pathway

Dr. Dilling said the genomic classifier should be considered part of a diagnostic pathway in uncertain cases, particularly when the risk of surgical lung biopsy is high.

Current clinical practice guidelines recommend surgical lung biopsy for histopathologic diagnosis when clinical and radiologic findings are not definitive for IPF, the speaker said.

However, surgical lung biopsy carries some risk, and sometimes it can’t be done, he added.

In his presentation, Dr. Dilling cited a systematic review and meta-analysis of 23 studies looking at surgical lung biopsy for the diagnosis of interstitial lung diseases.

The postoperative mortality rate was 3.6% in that meta-analysis, published in 2015 in the Journal of Thoracic and Cardiovascular Surgery.

“The final decision regarding whether or not to perform a [surgical lung biopsy] must be based on the balance between benefits to establish a secure diagnosis and the potential risks,” authors wrote at the time.

Mortality risk is higher in immunocompromised and acutely ill patient populations, according to Dr. Dilling, who added that as many of 19% of patients will have complications from surgical lung biopsy.
 

Genomic classifier studies

In a proof-of-principle study, published in 2017 in the Annals of the American Thoracic Society, authors described how they used machine learning to train an algorithm to distinguish UIP from non-UIP pattern in tissue obtained by transbronchial biopsy (TBB).

The top-performing algorithm distinguished UIP from non-UIP conditions in single TBB samples with specificity of 86% and sensitivity of 63%, according to investigators, who said at the time that independent validation would be needed before the genomic classifier could be applied in clinical settings.

In a prospective validation study, published in 2019 in The Lancet Respiratory Medicine, the genomic classifier identified UIP in TBB samples from 49 patients with a specificity of 88% and sensitivity of 70%.

Excluding patients with definite or probable UIP as shown on high-resolution computed tomography, results show that the classifier had a sensitivity of 76%, specificity of 88%, and positive predictive value of 81%.

“The performance of the test is good, even in that scenario,” Dr. Dilling said.
 

 

 

Real-world results

Dr. Dilling also highlighted a “real-world” study, published earlier in 2021, demonstrating that UIP pattern recognized by a genomic classifier had encouraging sensitivity and specificity when combined with high-resolution CT and clinical factors.

That study included 96 patients who had both diagnostic lung pathology and a transbronchial lung biopsy for molecular testing with the classifier.

The classifier had a sensitivity of 60.3% and a specificity of 92.1% for histology-proven UIP pattern, investigators said in their report, which appears in the American Journal of Respiratory and Critical Care Medicine.

Local radiologists identified UIP with a sensitivity of 34.0% and specificity of 96.9%. But adding genomic classifier testing to local radiology testing increased the diagnostic yield, investigators said, with a sensitivity of 79.2% and specificity of 90.6%.

“This might suggest that the implementation of this into a local [multidisciplinary discussion] with your local radiology expertise might really improve your recognition of UIP,” Dr. Dilling said.

Dr. Dilling reported disclosures related to Bellerophon, Boehringer Ingelheim, Genentech, Nitto Denko, and Lung Bioengineering.

Several emerging bronchoscopic treatments have the potential to improve the quality of life for patients with chronic obstructive pulmonary disease, an investigator reported at the annual meeting of the American College of Chest Physicians.

Targeted lung denervation is one promising novel therapeutic option that is safe and may improve clinical outcomes according to investigator Christian Ghattas, MD.

Data from an ongoing phase 3 randomized controlled trial may provide new information on the efficacy of targeted lung denervation in patients with chronic obstructive pulmonary disease (COPD), said Dr. Ghattas, assistant professor of medicine and associate program director for the interventional pulmonary fellowship at The Ohio State University Medical Center in Columbus.

“Outcome data of longer follow-up on previously treated patients will provide us with more information on the durability and the effect of this treatment,” Dr. Ghattas said in an online presentation at the CHEST meeting, which was held virtually this year.

Meanwhile, a few compelling bronchoscopic treatment modalities for patients with chronic bronchitis are in earlier stages of clinical development. “Larger randomized, controlled trials are ongoing to confirm the available data and to evaluate treatment durability,” said Dr. Ghattas.
 

Targeted lung denervation

The targeted lung denervation system under study (dNerva®, Nuvaira Inc.) involves the use of a radiofrequency catheter to ablate the peribronchial branches of the vagus nerve, Dr. Ghattas said.

The goal of disrupting pulmonary nerve input is to achieve sustained bronchodilation and reduce mucous secretion, thereby simulating the effect of anticholinergic drugs, he added.

In pilot studies, the targeted lung denervation system demonstrated its feasibility and safety, while modifications to the system reduced the rate of serious adverse events, according to Dr. Ghattas.

In the AIRFLOW-1 study, which evaluated the safety of the latest generation version of the system, 30 patients with COPD were randomized to targeted lung denervation at one of two doses, 29 or 32 watts.

Of those 30 patients, 29 (96.7%) had procedural success, meaning the catheter was inserted, guided to its intended location, and removed intact with no reported in-hospital serious adverse events, according to results published in Respiration.

There was no difference between arms in the primary endpoint, which was the rate of adverse airway effects requiring intervention that were associated with targeted lung denervation, investigators reported. Four such events occurred, in 3 of 15 patients treated with 32 watts and 1 of 15 patients treated with 29 watts.

Procedural success, defined as device success without an in-hospital serious adverse event, was 96.7% (29/30). The rate of TLD-associated adverse airway effects requiring intervention was 3/15 in the 32 W versus 1/15 in the 29 W group (P = .6). However, serious gastric events were noted in five patients, prompting safety improvements and procedural enhancements that reduced both gastrointestinal and airway events, according to the study report.

Further data are available from AIRFLOW-2, a randomized, sham-controlled trial enrolling patients with symptomatic COPD.

In that study, targeted lung denervation plus optimal drug treatment led to fewer respiratory adverse events of interest, including hospitalizations for COPD exacerbation, according to a report on the study that appears in The American Journal of Respiratory and Critical Care Medicine.

Respiratory adverse events occurred in 32% of treated patients versus 71% of sham-treated patients in a predefined 3- to 6.5-month postprocedure window, the report says.

Currently underway is AIRFLOW-3, a randomized study of targeted lung denervation versus sham procedure in patients with COPD. The study has a primary outcome measure of moderate or severe COPD exacerbations over 12 months and is slated to enroll 480 patients.

To be eligible for AIRFLOW-3, patients must have had at least two moderate or one severe COPD exacerbation in the previous year, Dr. Ghattas said.
 

 

 

Metered cryospray

One novel intervention with the potential to benefit patients with chronic bronchitis is metered cryospray (RejuvenAir), which works by delivering liquid nitrogen to the tracheobronchial airways, according to Dr. Ghattas.

This targeted delivery ablates abnormal epithelium, facilitating the regeneration of healthy mucosa, according to investigators in a recently published single-arm prospective trial.

Metered cryospray was safe, feasible, and linked to clinically meaningful improvements in patient-reported outcomes among patients with COPD, according to authors of the study, which appears in the European Respiratory Journal.

In the study, 34 of 35 participants received three treatments 4-6 weeks apart.

Investigators reported that at 3 months there were significant reductions in the COPD Assessment Test that were durable to 6 months, and changes in the St. George’s Respiratory Questionnaire and the Leicester Cough Questionnaire that were durable to 9 months.

There were 14 serious adverse events, none of which were device- or procedure related, according to investigators.

An ongoing randomized study called SPRAY-CB is comparing metered cryospray to sham procedure in an anticipated 210 patients with COPD with chronic bronchitis.
 

Bronchial rheoplasty

Bronchial rheoplasty (RheOx, Gala Therapeutics), is another promising intervention under investigation for the treatment of chronic bronchitis, according to Dr. Ghattas.

This system delivers nonthermal pulsed electrical energy, Dr. Ghattas said, with the intention of ablating goblet cells in the airways.

“The preclinical studies have demonstrated epithelial ablation, followed by regeneration of normalized epithelium,” he said in his presentation.

In 12-month results of multicenter clinical trial, bronchial rheoplasty was technically feasible and safe, with reductions in goblet cell hyperplasia and changes in patient-reported quality of life seen following the procedure, investigators reported in The American Journal of Respiratory and Critical Care Medicine.

The mean goblet cell hyperplasia score was reduced by 39% from baseline to treatment, according to study results. Four procedure-related serious adverse events were observed through 6 months, and there were no procedure- or device-related serious adverse events over the next 6 months. Mild hemoptysis occurred in 47% of patients, investigators reported.

A larger randomized, double-blind prospective trial with a sham control arm is underway and will include 270 patients, according to Dr. Ghattas. “We’re going to have to wait for the results,” he said.

Dr. Ghattas reported serving as a site principal investigator for clinical trials involving the bronchoscopic interventions he discussed, including AIRFLOW-3 (evaluating the targeted lung denervation system), SPRAY-CB (metered cryospray), and RheSolve (bronchial rheoplasty).

COVID-19 ICU visit restrictions add to staff stress, burnout

Article Type

Fri, 10/22/2021 - 13:00

During the COVID-19 pandemic, visitation in intensive care units has been restricted for obvious safety reasons, but such restrictions have contributed to the already serious strains on staff, results of a survey indicate.

Among 91 residents, nurse practitioners, and physician assistants who work in ICUs in the Emory Healthcare system, in Atlanta, two-thirds agreed that visitation restrictions were necessary, but nearly three-fourths said that the restrictions had a negative effect on their job satisfaction, and slightly more than half reported experiencing symptoms of burnout, wrote Nicole Herbst, MD, and Joanne Kuntz, MD, from Emory University School of Medicine.

“Because families are not present at bedside, restrictive visitation policies have necessitated that communication with families be more intentional and planned than before the COVID-19 pandemic. Understanding the ways these restrictions impact providers and patients can help guide future interventions to improve communication with families and reduce provider burnout,” the authors wrote in a poster presentation at the American College of Chest Physicians (CHEST) 2021 Annual Meeting.
 

Valid concerns, negative effects

“During the COVID pandemic, we fell back into old ways of doing things, where parents were restricted from the bedsides of patients in the intensive care unit. And I think we have shown over the last decade that family presence at the bedside significantly improves outcomes for patients and also helps clinicians caring for those patients,” commented Christopher Carroll, MD, FCCP, from Connecticut Children’s Medical Center, Hartford, in an interview.

“We had good reason to exclude visitors because we were worried about their own safety and their own health, but now 18 months into this pandemic, we know how to prevent COVID. We know now how to safely walk into the room of a patient who has COVID and walk out of it and not get infected. There’s no reason why we can’t relax these restrictions and allow families to be there with their loved ones,” continued Dr. Carroll, who was not involved in the study.

With visitation limited or banned outright, ICU staff have had to replace face-to-face discussion with more intentional, planned, and time-consuming methods, such as telephone calls and online video.

At the time of the survey, only two visitors were allowed to see patients in end-of-life situations in Emory ICUs. Exceptions to this rule were rare.
 

Study details

ICU staff members were asked about their communication practices, their attitudes about the effect of the restrictions on communication with families and job satisfaction, and about symptoms of burnout, using a validated single-item measure.

A total of 91 practitioners completed most of the survey questions. The results showed that more than half of all respondents (57.9%) reported spending more time communicating with families than they had the previous year.

A large majority (90.5%) also said that video communication (for example, with a tablet, personal device, or computer) was as effective or more effective than telephone communication.

In all, 64.3% of practitioners agreed that visitation restrictions were appropriate, but 71.4% said that the restrictions had a negative effect on their job satisfaction, and 51.8% reported experiencing symptoms of burnout, such as stress, low energy, exhaustion, or lack of motivation.

Casey Cable, MD, a pulmonary disease and critical care specialist at Virginia Commonwealth Medical Center, Richmond, Virginia, who was not involved in the study, did her fellowship at Emory. She told this news organization that the study findings might be skewed a bit by subjective impressions.

“I work in a level I trauma unit providing tertiary medical care, and we’re using more video to communicate with family members, more iPads,” she said. “Their finding is interesting that people felt that they were communicating more with family members, and I wonder if that’s a type of recall bias, because at the bedside, you can have a conversation, as opposed to actively talking to family members by calling them, videoing them, or whatnot, and I think that sticks in our head more, about putting in more effort. I don’t know if we are spending more time communicating with family or if that’s what we just recall.”

She agreed with the authors that visitation restrictions have a definite negative effect on job satisfaction and that they cause feelings of burnout.

“It’s tough not having families at bedside and offering them support. When visitors are not able to see how sick their family members are, it complicates discussions about end-of-life care, transitioning to comfort care, or maybe not doing everything,” she said.

No funding source for the study was reported. Dr. Herbst, Dr. Kuntz, Dr. Carroll, and Dr. Cable have disclosed no relevant financial relationships.

Sepsis multiplies in-hospital mortality risk in COPD

Article Type
Changed
Fri, 10/22/2021 - 13:01

Although slightly fewer than 1% of hospitalizations for chronic obstructive pulmonary disease (COPD) are complicated by sepsis, this complication increases the risk for in-hospital mortality fivefold, investigators who studied a representative national sample found.

Among nearly 7 million hospitalizations in which the primary diagnosis was COPD, nearly 65,000 (0.93%) patients experienced sepsis as a complication. In all, 31% of patients with COPD and sepsis were discharged from the hospital to another care facility, and 19% of patients died in hospital, report Harshil Shah, MD, from Guthrie Corning (N.Y.) Hospital and colleagues.

“Our study highlights the need for better risk stratification in patients with COPD developing sepsis to improve the outcomes. Further studies are warranted to consider factoring some of the modifiable factors into account and to ameliorate the outcomes of sepsis during COPD hospitalizations,” Dr. Shah and colleagues write in a poster presented during the at the annual meeting of the American College of Chest Physicians, held virtually this year.

COPD has been associated with increased risk for sepsis because of the use of corticosteroids, underlying comorbidities, and, potentially, because of impaired barrier function, the authors note.
 

Nationwide sample

To determine the effects of sepsis and predictors of poor outcomes among patients hospitalized for COPD, the investigators used standard diagnostic codes to identify patients with a primary diagnosis of COPD from the Nationwide Inpatient Sample for the period 2007 through 2018 and sepsis from codes in secondary fields in the International Classification of Diseases (9th/10th Editions) Clinical Modification.

They identified a total of 6,940,615 hospitalizations in which the primary diagnosis was COPD; in 64,748 of those cases, sepsis was a complication.

As noted, the in-hospital death rate, one of two primary outcomes, was 19% for patients with COPD and sepsis, and the rate of discharge to other facilities was 31%.

In analysis adjusted for confounding factors, sepsis was associated with an odds ratio for mortality of 4.9 (P < .01) and an OR for discharge to a facility of 2.2 (P < .01).

With regard to trends, the investigators saw that, although the adjusted odds for in-hospital mortality remained stable over time, discharge to facilities increased significantly. In 2007, the adjusted OR was 2.2, whereas in 2018, it was 2.6 (P for trend = .02).

Predictors of in-hospital mortality among patients with sepsis included increasing age (OR, not shown), White ethnicity (OR, 1.2), treatment in the Northeast region (OR, 1.4), disseminated intravascular coagulation (OR, 3.7), pneumococcal infection (OR, 1.2), congestive heart failure (OR, 1.2), and renal failure (OR, 1.4; P < .01 for all comparisons).
 

Mortality risk for many patients

A COPD specialist who was not involved in the study told this news organization that sepsis is an uncommon but serious complication, not just for patients with COPD but also for those with other severe illnesses.

“Sepsis has a high risk for mortality whether a person has COPD or not,” commented David M. Mannino III MD, FCCP, FERS, professor of medicine at the University of Kentucky, Lexington, and a cofounder and co–medical director of the COPD Foundation.

“It’s not surprising that sepsis is lethal in this population; the question is, if you have COPD, are you more likely to have sepsis? And I think the answer is probably yes. The connection there is that people with COPD have a higher risk for pneumonia, and pneumonia itself is probably one of the biggest risk factors, or certainly an important risk factor, for the development of sepsis,” he said in an interview.

It would be interesting to see the relationship between sepsis and in-hospital mortality for patients with other chronic diseases or people without COPD, he said, and he would have liked to have seen more detailed information about trends over time than Dr. Shah and colleagues provided.

No funding source for the study was reported. Dr. Shah and colleagues and Dr. Mannino have disclosed no relevant financial relationships.

Comorbidities larger factor than race in COVID ICU deaths?

Article Type
Changed
Fri, 10/22/2021 - 13:03

Racial/ethnic disparities in COVID-19 mortality rates may be related more to comorbidities than to demographics, suggest authors of a new study.

Researchers compared the length of stay in intensive care units in two suburban hospitals for patients with severe SARS-CoV-2 infections. Their study shows that although the incidence of comorbidities and rates of use of mechanical ventilation and death were higher among Black patients than among patients of other races, length of stay in the ICU was generally similar for patients of all races. The study was conducted by Tripti Kumar, DO, from Lankenau Medical Center, Wynnewood, Pennsylvania, and colleagues.

“Racial disparities are observed in the United States concerning COVID-19, and studies have discovered that minority populations are at ongoing risk for health inequity,” Dr. Kumar said in a narrated e-poster presented during the American College of Chest Physicians (CHEST) 2021 Annual Meeting.

“Primary prevention initiatives should take precedence in mitigating the effect that comorbidities have on these vulnerable populations to help reduce necessity for mechanical ventilation, hospital length of stay, and overall mortality,” she said.
 

Higher death rates for Black patients

At the time the study was conducted, the COVID-19 death rate in the United States had topped 500,000 (as of this writing, it stands at 726,000). Of those who died, 22.4% were Black, 18.1% were Hispanic, and 3.6% were of Asian descent. The numbers of COVID-19 diagnoses and deaths were significantly higher in U.S. counties where the proportions of Black residents were higher, the authors note.

To see whether differences in COVID-19 outcomes were reflected in ICU length of stay, the researchers conducted a retrospective chart review of data on 162 patients admitted to ICUs at Paoli Hospital and Lankenau Medical Center, both in the suburban Philadelphia town of Wynnewood.

All patients were diagnosed with COVID-19 from March through June 2020.

In all, 60% of the study population were Black, 35% were White, 3% were Asian, and 2% were Hispanic. Women composed 46% of the sample.

The average length of ICU stay, which was the primary endpoint, was similar among Black patients (15.4 days), White patients (15.5 days), and Asians (16 days). The shortest average hospital stay was among Hispanic patients, at 11.3 days.

The investigators determined that among all races, the prevalence of type 2 diabetesobesityhypertension, and smoking was highest among Black patients.

Overall, nearly 85% of patients required mechanical ventilation. Among the patients who required it, 86% were Black, 84% were White, 66% were Hispanic, and 75% were Asian.

Overall mortality was 62%. It was higher among Black patients, at 60%, than among White patients, at 33%. The investigators did not report mortality rates for Hispanic or Asian patients.
 

Missing data

Demondes Haynes, MD, FCCP, professor of medicine in the Division of Pulmonary and Critical Care and associate dean for admissions at the University of Mississippi Medical Center and School of Medicine, Jackson, who was not involved in the study, told this news organization that there are some gaps in the study that make it difficult to draw strong conclusions about the findings.

“For sure, comorbidities contribute a great deal to mortality, but is there something else going on? I think this poster is incomplete in that it cannot answer that question,” he said in an interview.

He noted that the use of retrospective rather than prospective data makes it hard to account for potential confounders.

“I agree that these findings show the potential contribution of comorbidities, but to me, this is a little incomplete to make that a definitive statement,” he said.

“I can’t argue with their recommendation for primary prevention – we definitely want to do primary prevention to decrease comorbidities. Would it decrease overall mortality? It might, it sure might, for just COVID-19 I’d say no, we need more information.”

No funding source for the study was reported. Dr. Kumar and colleagues and Dr. Haynes reported no relevant financial relationships.

“I agree that these findings show the potential contribution of comorbidities, but to me, this is a little incomplete to make that a definitive statement,” he said.

“I can’t argue with their recommendation for primary prevention – we definitely want to do primary prevention to decrease comorbidities. Would it decrease overall mortality? It might, it sure might, for just COVID-19 I’d say no, we need more information.”

No funding source for the study was reported. Dr. Kumar and colleagues and Dr. Haynes reported no relevant financial relationships.

Racial/ethnic disparities in COVID-19 mortality rates may be related more to comorbidities than to demographics, suggest authors of a new study.

Researchers compared the length of stay in intensive care units in two suburban hospitals for patients with severe SARS-CoV-2 infections. Their study shows that although the incidence of comorbidities and rates of use of mechanical ventilation and death were higher among Black patients than among patients of other races, length of stay in the ICU was generally similar for patients of all races. The study was conducted by Tripti Kumar, DO, from Lankenau Medical Center, Wynnewood, Pennsylvania, and colleagues.

“Racial disparities are observed in the United States concerning COVID-19, and studies have discovered that minority populations are at ongoing risk for health inequity,” Dr. Kumar said in a narrated e-poster presented during the American College of Chest Physicians (CHEST) 2021 Annual Meeting.

“Primary prevention initiatives should take precedence in mitigating the effect that comorbidities have on these vulnerable populations to help reduce necessity for mechanical ventilation, hospital length of stay, and overall mortality,” she said.
 

Higher death rates for Black patients

At the time the study was conducted, the COVID-19 death rate in the United States had topped 500,000 (as of this writing, it stands at 726,000). Of those who died, 22.4% were Black, 18.1% were Hispanic, and 3.6% were of Asian descent. The numbers of COVID-19 diagnoses and deaths were significantly higher in U.S. counties where the proportions of Black residents were higher, the authors note.

To see whether differences in COVID-19 outcomes were reflected in ICU length of stay, the researchers conducted a retrospective chart review of data on 162 patients admitted to ICUs at Paoli Hospital and Lankenau Medical Center, both in the suburban Philadelphia town of Wynnewood.

All patients were diagnosed with COVID-19 from March through June 2020.

In all, 60% of the study population were Black, 35% were White, 3% were Asian, and 2% were Hispanic. Women composed 46% of the sample.

The average length of ICU stay, which was the primary endpoint, was similar among Black patients (15.4 days), White patients (15.5 days), and Asians (16 days). The shortest average hospital stay was among Hispanic patients, at 11.3 days.

The investigators determined that among all races, the prevalence of type 2 diabetesobesityhypertension, and smoking was highest among Black patients.

Overall, nearly 85% of patients required mechanical ventilation. Among the patients who required it, 86% were Black, 84% were White, 66% were Hispanic, and 75% were Asian.

Overall mortality was 62%. It was higher among Black patients, at 60%, than among White patients, at 33%. The investigators did not report mortality rates for Hispanic or Asian patients.
 

Missing data

Demondes Haynes, MD, FCCP, professor of medicine in the Division of Pulmonary and Critical Care and associate dean for admissions at the University of Mississippi Medical Center and School of Medicine, Jackson, who was not involved in the study, told this news organization that there are some gaps in the study that make it difficult to draw strong conclusions about the findings.

“For sure, comorbidities contribute a great deal to mortality, but is there something else going on? I think this poster is incomplete in that it cannot answer that question,” he said in an interview.

He noted that the use of retrospective rather than prospective data makes it hard to account for potential confounders.

“I agree that these findings show the potential contribution of comorbidities, but to me, this is a little incomplete to make that a definitive statement,” he said.

“I can’t argue with their recommendation for primary prevention – we definitely want to do primary prevention to decrease comorbidities. Would it decrease overall mortality? It might, it sure might, for just COVID-19 I’d say no, we need more information.”

Fungal infection can mimic lung cancer metastases

Article Type
Changed
Wed, 10/20/2021 - 15:25

A fungal infection typically seen in the lungs may have a variety of unusual clinical presentations elsewhere in the body, even raising suspicion of cancer in some cases, a medical resident reported at the annual meeting of the American College of Chest Physicians.

In one recent and unusual presentation, a 58-year-old woman with persistent headaches had skull lesions on computed tomography (CT) was eventually diagnosed with disseminated coccidioidomycosis (Valley fever), a fungal infection endemic to the Southwestern U.S.

The imaging pattern of her head CT was initially concerning for cancer metastasis, according to Sharjeel Israr, MD, a third-year internal medicine resident at Creighton University in Phoenix, Ariz.

However, the subsequent chest CT revealed a suspicious chest mass. A biopsy of that mass led to the correct diagnosis of disseminated coccidioidomycosis, according to Dr. Israr, who presented the case report in an e-poster at the CHEST meeting, which was held virtually this year.
 

Mistaken identity

Coccidioidomycosis, caused by the fungus Coccidioides, usually affects the lungs, according to the Centers for Disease Control and Prevention. However, in severe cases it can spread to other parts of the body. In those cases, it’s referred to as disseminated coccidioidomycosis.

Arizona accounted for about 10,000 out of 18,000 reported Valley fever cases in 2019, according to the latest statistics from the CDC.

Coccidioidomycosis is frequently mistaken not only for cancer, but also for rheumatic conditions and bacterial infections, according to Valley fever specialist John Galgiani, MD, director of the Valley Fever Center for Excellence at the University of Arizona in Tucson.

“Where Valley fever is common, it should very frequently be in the differential for masses that are thought to be cancer,” Dr. Galgiani said in an interview. “This case is a good example of that.”
 

Challenging case

In an interview, Dr. Israr said the case was challenging to crack despite the fact that Valley fever is very common in Phoenix.

“It was definitely on the differential from the get-go, but it was very, very low our differential, just based on the presentation that she had,” said Dr. Israr.

The patient had history of diabetes and presented with headaches for 4 weeks. However, she had no pulmonary symptoms or meningeal signs, according to Dr. Israr.

A head CT revealed multiple osseous skull lesions and a left temporal lobe lesion.

“The fact that this patient had lesions in the skull, specifically, is something that raised our initial red flags for cancer – especially since she presented with just a headache as her only complaint,” he said.

The imaging pattern was concerning for metastasis, according to Dr. Israr, particularly since a subsequent CT of the chest showed multiple pulmonary nodules plus a 7.7-cm mass in the right lower lobe.

Once the biopsy confirmed coccidioidomycosis, the patient was started on fluconazole 600 mg twice daily, according to Dr. Israr.

Although severe disseminated coccidioidomycosis can be difficult to treat, the lung lesion had decreased in size from 7.7 cm to 4.2 cm about 3 months later, Dr. Israr said.

“At the end of the day, she didn’t have cancer, and it’s something that we’re treating and she’s actually doing better right now,” Dr. Israr said in the interview.

Dr. Israr and coauthors of the case reported they had no relevant relationships to disclose.

Life-threatening paradoxical bronchospasm may escape recognition in patients with COPD or asthma

Article Type

Tue, 10/19/2021 - 12:19

A rare and potentially life-threatening adverse effect of bronchodilator therapy may be overlooked among patients with chronic obstructive pulmonary disease (COPD) or asthma, according to a researcher who reviewed spirometry test results from U.S. military veterans.

Nearly 1.5% of the tests met the criteria for paradoxical bronchospasm, which refers to airway constriction that may rapidly occur after inhalation of a short-acting beta2 agonist (SABA) such as albuterol.

However, none of those reports alluded to paradoxical bronchospasm, said investigator Malvika Kaul, MD, fellow in the department of pulmonary and critical care at the University of Illinois at Chicago and the Jesse Brown Veterans Affairs Medical Center, also in Chicago.

“Paradoxical bronchospasm was neither recognized nor reported in any spirometry test results,” Dr. Kaul said in an online poster presentation at the annual meeting of the American College of Chest Physicians, held virtually this year.

By recognizing paradoxical bronchospasm, health care providers could address its clinical implications and identify potential alternative management options, according to Dr. Kaul.

“We hope in the future, education of clinicians about this phenomena is emphasized,” Dr. Kaul said in her presentation.
 

Recognizing paradoxical bronchospasm

In an interview, Dr. Kaul said she began researching paradoxical bronchospasm after encountering a patient who had an acute reaction to albuterol during a pulmonary function test.

“I was not taught about it, and I wasn’t recognizing that pattern very frequently in my patients,” she said.

Prescribing information for Food and Drug Administration–approved SABAs include a warning that life-threatening paradoxical bronchospasm may occur, said Dr. Kaul.

If paradoxical bronchospasm occurs, the patient should discontinue the medication immediately and start on alternative therapy, according to the available prescribing information for albuterol sulfate.

Paradoxical bronchospasm has been linked to worsened respiratory outcomes, including more frequent exacerbations, in patients with obstructive lung diseases, according to Dr. Kaul.

Two previous large studies pegged the prevalence of paradoxical bronchospasm at around 4.5% in patients with COPD or asthma, but “it has not been reported or addressed in high-risk population, such as veterans who have high prevalence of obstructive lung diseases like COPD,” Dr. Kaul said.
 

Latest study results

Dr. Kaul described a retrospective analysis of 1,150 pre- and postbronchodilator spirometry tests conducted in patients with COPD or asthma at the Jesse Brown VA Medical Center between 2017 and 2020.

A positive paradoxical bronchodilator response was defined as a decrease of least 12% and 200 mL in forced expiratory volume in 1 second and forced vital capacity from baseline after four puffs of albuterol were inhaled, Dr. Kaul said.

Out of 18 reviewed spirometry results that met the criteria, none of the test results reported or recognized paradoxical bronchospasm, according to Dr. Kaul.

Those meeting the criteria were predominantly COPD patients, according to Dr. Kaul, who said 12 had an underlying diagnosis COPD, 4 had asthma, and 2 had COPD and asthma.

Of the 18 patients, 13 were African American, and all but 1 of the 18 patients had a current or past smoking history, according to reported data.

A history of obstructive sleep apnea was reported in nine patients, and history of gastroesophageal reflux disease was also reported in nine patients. Eleven patients had emphysema.
 

Greater awareness needed

Results of this study emphasize the need to recognize potential cases paradoxical bronchospasm in clinical practice, as well as a need for more research, according to Allen J. Blaivas, DO, FCCP, chair of the CHEST Airway Disorders NetWork.

“It’s something to be on the alert for, and certainly be aware that, if your patient is telling you that they feel worse, we shouldn’t just pooh-pooh it,” said Dr. Blaivas, who is medical director of the intensive care unit at the East Orange campus of the VA New Jersey Health Care System.

Further research could focus on breaking down whether patients with suspected paradoxical bronchospasm are using metered-dose inhalers or nebulizers, whether or not they are also taking inhaled corticosteroids, and whether prospective testing can confirm paradoxical bronchospasm in patients who report tightness after using a SABA, he said in an interview.

Dr. Kaul and coauthor Israel Rubinstein, MD had no relevant relationships to disclose. Dr. Blaivas had no relevant relationships to disclose.

Mortality in 2nd wave higher with ECMO for COVID-ARDS

Article Type
Changed
Tue, 10/19/2021 - 14:33

For patients with refractory acute respiratory distress syndrome (ARDS) caused by COVID-19 infections, extracorporeal membrane oxygenation (ECMO) may be the treatment of last resort.

But for reasons that aren’t clear, in the second wave of the COVID-19 pandemic at a major teaching hospital, the mortality rate of patients on ECMO for COVID-induced ARDS was significantly higher than it was during the first wave, despite changes in drug therapy and clinical management, reported Rohit Reddy, BS, a second-year medical student, and colleagues at Thomas Jefferson University Hospital in Philadelphia.

During the first wave, from April to September 2020, the survival rate of patients while on ECMO in their ICUs was 67%. In contrast, for patients treated during the second wave, from November 2020 to March 2021, the ECMO survival rate was 31% (P = .003).

The 30-day survival rates were also higher in the first wave compared with the second, at 54% versus 31%, but this difference was not statistically significant.

“More research is required to develop stricter inclusion/exclusion criteria and to improve pre-ECMO management in order to improve outcomes,” Mr. Reddy said in a narrated poster presented at the annual meeting of the American College of Chest Physicians, held virtually this year.
 

ARDS severity higher

ARDS is a major complication of COVID-19 infections, and there is evidence to suggest that COVID-associated ARDS is more severe than ARDS caused by other causes, the investigators noted.

“ECMO, which has been used as a rescue therapy in prior viral outbreaks, has been used to support certain patients with refractory ARDS due to COVID-19, but evidence for its efficacy is limited. Respiratory failure remained a highly concerning complication in the second wave of the COVID-19 pandemic, but it is unclear how the evolution of the disease and pharmacologic utility has affected the clinical utility of ECMO,” Mr. Reddy said.

To see whether changes in disease course or in treatment could explain changes in outcomes for patients with COVID-related ARDS, the investigators compared characteristics and outcomes for patients treated in the first versus second waves of the pandemic. Their study did not include data from patients infected with the Delta variant of the SARS-CoV-2 virus, which became the predominant viral strain later in 2021.

The study included data on 28 patients treated during the first wave, and 13 during the second. The sample included 28 men and 13 women with a mean age of 51 years.

All patients had venovenous ECMO, with cannulation in the femoral or internal jugular veins; some patients received ECMO via a single double-lumen cannula.

There were no significant differences between the two time periods in patient comorbidities prior to initiation of ECMO.

Patients in the second wave were significantly more likely to receive steroids (54% vs. 100%; P = .003) and remdesivir (39% vs. 85%; P = .007). Prone positioning before ECMO was also significantly more frequent in the second wave (11% vs. 85%; P < .001).

Patients in the second wave stayed on ECMO longer – median 20 days versus 14 days for first-wave patients – but as noted before, ECMO mortality rates were significantly higher during the second wave. During the first wave, 33% of patients died while on ECMO, compared with 69% in the second wave (P = .03). Respective 30-day mortality rates were 46% versus 69% (ns).

Rates of complications during ECMO were generally comparable between the groups, including acute renal failure (39% in the first wave vs 38% in the second), sepsis (32% vs. 23%), bacterial pneumonia (11% vs. 8%), and gastrointestinal bleeding (21% vs. 15%). However, significantly more patients in the second wave had cerebral vascular accidents (4% vs. 23%; P = .050).

Senior author Hitoshi Hirose, MD, PhD, professor of surgery at Thomas Jefferson University, said in an interview that the difference in outcomes was likely caused by changes in pre-ECMO therapy between the first and second waves.

“Our study showed the incidence of sepsis had a large impact on the patient outcomes,” he wrote. “We speculate that sepsis was attributed to use of immune modulation therapy. The prevention of the sepsis would be key to improve survival of ECMO for COVID 19.”

“It’s possible that the explanation for this is that patients in the second wave were sicker in a way that wasn’t adequately measured in the first wave,” CHEST 2021 program cochair Christopher Carroll, MD, FCCP, from Connecticut Children’s Medical Center in Hartford, said in an interview.

The differences may also have been attributable to changes in virulence, or to clinical decisions to put sicker patients on ECMO, he said.

Casey Cable, MD, MSc, a pulmonary disease and critical care specialist at Virginia Commonwealth Medical Center in Richmond, also speculated in an interview that second-wave patients may have been sicker.

“One interesting piece of this story is that we now know a lot more – we know about the use of steroids plus or minus remdesivir and proning, and patients received a large majority of those treatments but still got put on ECMO,” she said. “I wonder if there is a subset of really sick patients, and no matter what we treat with – steroids, proning – whatever we do they’re just not going to do well.”

Both Dr. Carroll and Dr. Cable emphasized the importance of ECMO as a rescue therapy for patients with severe, refractory ARDS associated with COVID-19 or other diseases.

Neither Dr. Carroll nor Dr. Cable were involved in the study.

No study funding was reported. Mr. Reddy, Dr. Hirose, Dr. Carroll, and Dr. Cable disclosed no relevant financial relationships.

For patients with refractory acute respiratory distress syndrome (ARDS) caused by COVID-19 infections, extracorporeal membrane oxygenation (ECMO) may be the treatment of last resort.

But for reasons that aren’t clear, in the second wave of the COVID-19 pandemic at a major teaching hospital, the mortality rate of patients on ECMO for COVID-induced ARDS was significantly higher than it was during the first wave, despite changes in drug therapy and clinical management, reported Rohit Reddy, BS, a second-year medical student, and colleagues at Thomas Jefferson University Hospital in Philadelphia.

During the first wave, from April to September 2020, the survival rate of patients while on ECMO in their ICUs was 67%. In contrast, for patients treated during the second wave, from November 2020 to March 2021, the ECMO survival rate was 31% (P = .003).

The 30-day survival rates were also higher in the first wave compared with the second, at 54% versus 31%, but this difference was not statistically significant.

“More research is required to develop stricter inclusion/exclusion criteria and to improve pre-ECMO management in order to improve outcomes,” Mr. Reddy said in a narrated poster presented at the annual meeting of the American College of Chest Physicians, held virtually this year.
 

ARDS severity higher

ARDS is a major complication of COVID-19 infections, and there is evidence to suggest that COVID-associated ARDS is more severe than ARDS caused by other causes, the investigators noted.

“ECMO, which has been used as a rescue therapy in prior viral outbreaks, has been used to support certain patients with refractory ARDS due to COVID-19, but evidence for its efficacy is limited. Respiratory failure remained a highly concerning complication in the second wave of the COVID-19 pandemic, but it is unclear how the evolution of the disease and pharmacologic utility has affected the clinical utility of ECMO,” Mr. Reddy said.

To see whether changes in disease course or in treatment could explain changes in outcomes for patients with COVID-related ARDS, the investigators compared characteristics and outcomes for patients treated in the first versus second waves of the pandemic. Their study did not include data from patients infected with the Delta variant of the SARS-CoV-2 virus, which became the predominant viral strain later in 2021.

The study included data on 28 patients treated during the first wave, and 13 during the second. The sample included 28 men and 13 women with a mean age of 51 years.

All patients had venovenous ECMO, with cannulation in the femoral or internal jugular veins; some patients received ECMO via a single double-lumen cannula.

There were no significant differences between the two time periods in patient comorbidities prior to initiation of ECMO.

Patients in the second wave were significantly more likely to receive steroids (54% vs. 100%; P = .003) and remdesivir (39% vs. 85%; P = .007). Prone positioning before ECMO was also significantly more frequent in the second wave (11% vs. 85%; P < .001).

Patients in the second wave stayed on ECMO longer – median 20 days versus 14 days for first-wave patients – but as noted before, ECMO mortality rates were significantly higher during the second wave. During the first wave, 33% of patients died while on ECMO, compared with 69% in the second wave (P = .03). Respective 30-day mortality rates were 46% versus 69% (ns).

Rates of complications during ECMO were generally comparable between the groups, including acute renal failure (39% in the first wave vs 38% in the second), sepsis (32% vs. 23%), bacterial pneumonia (11% vs. 8%), and gastrointestinal bleeding (21% vs. 15%). However, significantly more patients in the second wave had cerebral vascular accidents (4% vs. 23%; P = .050).

COVID-19, yes, but so much more

Article Type
Changed
Tue, 10/19/2021 - 08:44

Nearly 2 years into the pandemic, all things COVID-19 will of course be a major focus at the annual meeting of the American College of Chest Physicians, held virtually this year.

“During the pandemic, critical care has been at the forefront of what people are interested in,” said CHEST 2021 program cochair Christopher Carroll, MD, FCCP, from Connecticut Children’s Medical Center, Hartford.

“There is so much volume in critical care units that people have interest in anything related to critical care, including infectious diseases and disaster management in critical care,” he said in an interview.

Sessions at this year’s meeting that have a COVID-19 theme will focus on care of both patients and caregivers. Multiple symposiums, oral abstracts, scientific posters, and case reports will focus on clinical aspects of SARS-CoV-2 infections and COVID-19, including complications such as ventilator-associated and hospital-acquired pneumonia, a session called “Viruses, Variants, Vaccines, and Virulence: The Present and Future of COVID-19,” and support of patients and families.

Other presentations will focus on how COVID-19 has affected lung cancer screening, outpatient practices, pulmonary care, and sleep medicine.

Importantly, the meeting will include sessions focusing on the mental, physical, and social health of clinicians, especially those on the front lines in critical care and intensive care units. There will be sessions on how to recognize and avoid burnout, practice mental health awareness, and take time for self-care.

Presidential Honor Lecturer Curtis N. Sessler, MD, Master FCCP, FCCM, of Virginia Commonwealth University, Richmond, with give a talk titled, “Navigating the Road to Well-Being in the ICU.”
 

Empathy and diversity

Program cochair David Zielinski, MD, FCCP, of Montreal Children’s Hospital, Quebec, told this news organization that the COVID-19 pandemic has brought into even starker contrast inequities in patient care and in the health care system at large.

“This is a subject people are very keen about right now, whether it’s about how providers are treated, opportunities for improvement, or correcting inequities in outcomes for patients,” he said in an interview.

The program doesn’t shy away from the controversy, either, with a session provocatively titled, “Racism in Health Care: The Fuel That Lit the COVID-19 Fire.”

Keynote speaker Demondes Haynes, MD, FCCP, professor of medicine and associate dean of admissions at the University of Mississippi, Jackson, will speak on the importance of empathy in physician-patient communications and on ways to create a more diverse and inclusive workforce in medicine.
 

Beyond COVID-19

CHEST 2021 will include important information for sleep medicine physicians, including the latest news regarding an equipment recall affecting one of the two major manufacturers of continuous positive airway pressure devices.

“This has caused a lot of angst among sleep physicians and patients, and there are not enough devices to replace them,” Dr. Zielinski said.

“People who are on home ventilators are also affected by this recall,” Dr. Carroll added. “The population of patients who have sleep apnea is much greater than the population who are on home ventilators, but patients who are on home ventilators need it to save their lives.”

The meeting will include informative sessions summarizing U.S. and European asthma guidelines published over the past 2 years, as well as pending guidelines from the American College of Chest Physicians on venous thromboembolism and lung cancer screening.

Additional topics of importance include chronic obstructive pulmonary disease, interstitial lung disease, asthma management, acute respiratory failure in special populations, new therapies and strategies for treating tuberculosis, and many others.

There will be skill-polishing simulation sessions designed to help clinicians connect with experts in the field, update their knowledge, and sharpen their technique.
 

Fun and games

In addition to the serious subjects, CHEST 2021 attendees will have the chance to network with colleagues and friends and enjoy online games, including the 20th annual CHEST Challenge, which will pit teams of fellows-in-training from the Interfaith Medical Center, in Brooklyn, New York; the State University of New York, in Buffalo; and the Ohio State University Medical Center, in Columbus, in a Jeopardy!-style battle of wits and medical knowledge.

Close to 7,000 registrants from around the world took part in last year’s CHEST annual meeting, and a similar number is expected for this year’s edition, Dr. Carroll and Dr. Zielinski said.

Dupilumab-improved lung function lasts in children with moderate to severe asthma

Article Type
Changed
Mon, 10/18/2021 - 09:47

Add-on treatment with dupilumab may improve lung function in children aged 6-11 years with uncontrolled moderate to severe type 2 inflammatory asthma, results from a randomized, placebo-controlled, phase 3 study show.

Dr. Leonard B. Bacharier
Dr. Leonard B. Bacharier

Improvements in lung function parameters were observed as early as 2 weeks and persisted over the 52-week treatment period among children in the LIBERTY ASTHMA VOYAGE study, according to investigator Leonard B. Bacharier, MD, of Monroe Carell Jr. Children’s Hospital at Vanderbilt University Medical Center, Nashville, Tenn.

“Dupilumab led to clinically meaningful rapid and sustained improvements in lung function parameters,” Dr. Bacharier said in an online poster presentation at the annual meeting of the American College of Chest Physicians, held virtually this year.

The improvements in forced expiratory volume in 1 second (FEV1) and other measures reported for children with moderate to severe asthma who have the type 2 phenotype, which is the most common driver of pediatric asthma, according to Dr. Bacharier.

“Many children with moderate to severe asthma have abnormal lung function, and this can be a risk factor for future lung disease in adulthood,” Dr. Bacharier said in his presentation.
 

The VOYAGE continues

The findings presented at the meeting build on another report earlier this year from the LIBERTY ASTHMA VOYAGE study demonstrating that add-on dupilumab treatment led to a significant improvement versus placebo in FEV1 up to 12 weeks.

“We now have a long term data on this drug as well, showing its efficacy over a period of time,” said Muhammad Adrish, MD, MBA, FCCP, associate professor of pulmonary, critical care and sleep medicine at Baylor College of Medicine, Houston.

“I think that’s pretty exciting, and that’s another step towards precision medicine in treatment of asthma,” Dr. Adrish, who is Vice-Chair of CHEST’s Airways Disorders NetWork Steering Committee and was not involved in the study.

Dupilumab received Food and Drug Administration approval in 2018 as add-on maintenance therapy for the treatment of patients aged 12 years or older with moderate to severe asthma that has an eosinophilic phenotype or that is dependent on oral corticosteroid treatment.

In March 2021, Sanofi and Regeneron announced that the FDA had accepted for review a supplemental Biologics License Application for dupilumab as an add-on treatment in children aged 6-11 years with uncontrolled moderate to severe asthma.

That sBLA is supported by data from the LIBERTY ASTHMA VOYAGE study, Sanofi and Regeneron said.

In results of the phase 3 study that Dr. Bacharier presented in May at the American Thoracic Society International Conference, add-on dupilumab dosed every 2 weeks significant improved percent predicted prebronchodilator FEV1 by an additional 5.21 percentage points versus placebo at week 12.
 

Dupilumab and the type 2 phenotype

The new data reported at the CHEST meeting come from a prespecified analysis evaluating the impact of dupilumab on lung function over a 52-week treatment period in patients with a T2 inflammatory asthma phenotype.

“Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and -13, key and central drivers of T2 inflammation in multiple diseases,” Dr. Bacharier and coinvestigators reported in their study abstract.

Of 408 patients in the study, 350 met the T2 phenotype criteria, including 236 in the dupilumab arm and 114 in the placebo arm.

Patients met T2 phenotype criteria if they had blood eosinophils of at least 150 cells/mcL or fractional exhaled nitric oxide FeNO of at least 20 parts per billion at baseline, investigators said.

Dr. Bacharier and coinvestigators reported on several different endpoints, including absolute and percent predicted prebronchodilator FEV1, percent predicted postbronchodilator FEV1, prebronchodilator forced expiratory flow at 25%-75% of pulmonary volume (FEF25%-75%), and forced vital capacity (FVC).

Dupilumab, when compared with placebo, significantly improved prebronchodilator FEV1 in pediatric patients with uncontrolled moderate to severe type 2 asthma, according to Dr. Bacharier.

“Patients receiving dupilumab experienced rapid improvements by week 2, and this was sustained for up to 52 weeks,” he said.

The prebronchodilator FEV1 improved from baseline for dupilumab versus placebo, with a least squares mean difference of 0.06 L at week 2, which reached 0.17 L by week 52, according to their data. Similarly, postbronchodilator FEV1 improved from baseline for dupilumab, with a least square mean difference versus placebo of 0.09 L at week 52.

Dupilumab compared to placebo also significantly improved percent predicted FEF25%-75%, and percent predicted FVC over the 52-week treatment period, according to Dr. Bacharier.

“Dupilumab led to significant, rapid, and sustained improvements in multiple aspects of lung function in children aged 6-11 years,” Dr. Bacharier added in a CHEST press release that described the findings.

The LIBERTY ASTHMA VOYAGE study was sponsored by Sanofi and Regeneron Pharmaceuticals. Dr. Bacharier provided disclosures related to AstraZeneca, GlaxoSmithKline, Regeneron Pharmaceuticals, Sanofi, CF Foundation, DBV Technologies, NIH, and Vectura.

“We now have a long term data on this drug as well, showing its efficacy over a period of time,” said Muhammad Adrish, MD, MBA, FCCP, associate professor of pulmonary, critical care and sleep medicine at Baylor College of Medicine, Houston.

“I think that’s pretty exciting, and that’s another step towards precision medicine in treatment of asthma,” Dr. Adrish, who is Vice-Chair of CHEST’s Airways Disorders NetWork Steering Committee and was not involved in the study.

Dupilumab received Food and Drug Administration approval in 2018 as add-on maintenance therapy for the treatment of patients aged 12 years or older with moderate to severe asthma that has an eosinophilic phenotype or that is dependent on oral corticosteroid treatment.

In March 2021, Sanofi and Regeneron announced that the FDA had accepted for review a supplemental Biologics License Application for dupilumab as an add-on treatment in children aged 6-11 years with uncontrolled moderate to severe asthma.

That sBLA is supported by data from the LIBERTY ASTHMA VOYAGE study, Sanofi and Regeneron said.

In results of the phase 3 study that Dr. Bacharier presented in May at the American Thoracic Society International Conference, add-on dupilumab dosed every 2 weeks significant improved percent predicted prebronchodilator FEV1 by an additional 5.21 percentage points versus placebo at week 12.
 

Dupilumab and the type 2 phenotype

The new data reported at the CHEST meeting come from a prespecified analysis evaluating the impact of dupilumab on lung function over a 52-week treatment period in patients with a T2 inflammatory asthma phenotype.

“Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and -13, key and central drivers of T2 inflammation in multiple diseases,” Dr. Bacharier and coinvestigators reported in their study abstract.

Of 408 patients in the study, 350 met the T2 phenotype criteria, including 236 in the dupilumab arm and 114 in the placebo arm.

Patients met T2 phenotype criteria if they had blood eosinophils of at least 150 cells/mcL or fractional exhaled nitric oxide FeNO of at least 20 parts per billion at baseline, investigators said.

Dr. Bacharier and coinvestigators reported on several different endpoints, including absolute and percent predicted prebronchodilator FEV1, percent predicted postbronchodilator FEV1, prebronchodilator forced expiratory flow at 25%-75% of pulmonary volume (FEF25%-75%), and forced vital capacity (FVC).

Dupilumab, when compared with placebo, significantly improved prebronchodilator FEV1 in pediatric patients with uncontrolled moderate to severe type 2 asthma, according to Dr. Bacharier.

“Patients receiving dupilumab experienced rapid improvements by week 2, and this was sustained for up to 52 weeks,” he said.

The prebronchodilator FEV1 improved from baseline for dupilumab versus placebo, with a least squares mean difference of 0.06 L at week 2, which reached 0.17 L by week 52, according to their data. Similarly, postbronchodilator FEV1 improved from baseline for dupilumab, with a least square mean difference versus placebo of 0.09 L at week 52.

Dupilumab compared to placebo also significantly improved percent predicted FEF25%-75%, and percent predicted FVC over the 52-week treatment period, according to Dr. Bacharier.

“Dupilumab led to significant, rapid, and sustained improvements in multiple aspects of lung function in children aged 6-11 years,” Dr. Bacharier added in a CHEST press release that described the findings.

The LIBERTY ASTHMA VOYAGE study was sponsored by Sanofi and Regeneron Pharmaceuticals. Dr. Bacharier provided disclosures related to AstraZeneca, GlaxoSmithKline, Regeneron Pharmaceuticals, Sanofi, CF Foundation, DBV Technologies, NIH, and Vectura.

Add-on treatment with dupilumab may improve lung function in children aged 6-11 years with uncontrolled moderate to severe type 2 inflammatory asthma, results from a randomized, placebo-controlled, phase 3 study show.

Improvements in lung function parameters were observed as early as 2 weeks and persisted over the 52-week treatment period among children in the LIBERTY ASTHMA VOYAGE study, according to investigator Leonard B. Bacharier, MD, of Monroe Carell Jr. Children’s Hospital at Vanderbilt University Medical Center, Nashville, Tenn.

“Dupilumab led to clinically meaningful rapid and sustained improvements in lung function parameters,” Dr. Bacharier said in an online poster presentation at the annual meeting of the American College of Chest Physicians, held virtually this year.

The improvements in forced expiratory volume in 1 second (FEV1) and other measures reported for children with moderate to severe asthma who have the type 2 phenotype, which is the most common driver of pediatric asthma, according to Dr. Bacharier.

“Many children with moderate to severe asthma have abnormal lung function, and this can be a risk factor for future lung disease in adulthood,” Dr. Bacharier said in his presentation.
