Asthma

TOPLINE:

Children with asthma exposed to worsening psychosocial environmental factors during childhood were more likely to have more severe asthma symptoms than those without such exposures.

METHODOLOGY:

• The researchers reviewed data from the Longitudinal Study of Australian Children, a nationally representative cohort that also collects data on the health, psychosocial, and environmental status of parents, and used three multivariate models to assess the impact of psychosocial environmental factors on asthma symptoms at ages 1 year, 4-5 years, and 14-15 years.
• The study population included 3,917 children aged 0-15 years who were sorted into three asthma symptom trajectory groups (low/no asthma, transient high asthma, and persistent high asthma); asthma symptoms were defined as a history of chest wheezing lasting at least a week within the past 12 months.
• The researchers identified several psychosocial environmental factors as exposure variables on the basis of literature reviews; these factors were maternal depression, parents’ financial hardship, parental availability, and parental stressful life events.

TAKEAWAY:

• The mean scores of psychosocial factors for the overall study population remained stable over time, but groups of children exposed to bad trajectories of psychosocial factors were significantly more likely to have transient high and persistent high asthma symptoms.
• In the first year of life, only parents’ stressful life events were significantly associated with the persistent high asthma symptom trajectory group in an adjusted analysis.
• At age 4-5 years, maternal depression, low parental availability, and parents’ stressful life events were significantly associated with persistent high asthma; parents’ financial hardship was significantly associated with transient high asthma symptoms.
• At age 14-15 years, children exposed to “moderate and increasing” maternal depression, “moderate and declining” parents’ financial hardship, and “moderate and increasing” parents’ stressful life events were significantly associated with persistent high asthma versus no or low asthma, with relative risk ratios of 1.55, 1.40, and 1.77, respectively.

IN PRACTICE:

The study findings highlight the need for policy makers to take action to improve asthma control in children by reducing exposure to harmful psychosocial environmental factors, the researchers concluded.

SOURCE:

The lead author of the study was K.M. Shahunja, MBBS, PhD candidate at the University of Queensland, Brisbane, Australia. The study was published online in Pediatric Pulmonology.

LIMITATIONS:

The study is the first known to examine asthma symptom trajectories at different developmental stages, but participant attrition and missing values were limiting factors, as was the inability to account for all potential psychosocial environmental factors that might influence asthma symptoms in childhood.

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.

ANAHEIM, CALIF. – Gargling and nasal rinsing with saltwater several times a day appeared to be associated with significantly lower COVID-19 hospitalization rates in a small, randomized, double-blind, controlled study.

“The hypothesis was that interventions that target the upper respiratory tract may reduce the frequency and duration of upper respiratory symptoms associated with COVID-19,” said Sebastian Espinoza, first author of the study; he is with Trinity University, San Antonio.

Adults aged 18-65 years who tested positive for SARS-CoV-2 on polymerase chain reaction (PCR) testing between 2020 and 2022 were randomly selected to use low- or high-dose saltwater regimens for 14 days at the Harris Health System, Houston. For patients to be included in the study, 14 days had to have elapsed since the onset of any symptoms associated with COVID.

The low dose was 2.13 grams of salt dissolved in 8 ounces of warm water, and the high dose was 6 grams. Participants gargled the saltwater and used it as a nasal rinse for 5 minutes four times a day.

Primary outcomes included frequency and duration of symptoms associated with SARS-CoV-2 infection; secondary outcomes included admission to the hospital or the intensive care unit, mechanical ventilatory support, or death.

The findings were presented in a poster at the annual meeting of the American College of Allergy, Asthma, and Immunology.

Fifty-eight people were randomly assigned to either the low-saline (n = 27) or the high-saline (n = 28) group; three patients were lost to follow-up in both these groups. The reference control population consisted of 9,398 people with confirmed SARS-CoV-2 infection. Rates of vaccination were similar for all participants.

Hospitalization rates in the low- (18.5%) and high- (21.4%) saline groups were significantly lower than in the reference control population (58.8%; P < .001). No significant differences were noted in other outcomes among these groups.

The average age of patients in the control population (n = 9,398) was 45 years. The average age was similar in the low- and high-saline groups. In the low-saline group (n = 27), the average age was 39, and in the high-saline group, the average age was 41.

In all three groups, body mass index was between 29.6 and 31.7.

Exclusion criteria included chronic hypertension or participation in another interventional study.
 

‘Low risk, small potential benefit’

Allergist Zach Rubin, MD, a spokesperson for the ACAAI, said in an interview that the findings are in line with other small studies that previously reported some benefit in using nasal saline irrigation and gargling to treat a SARS-CoV-2 infection.

“This is a type of intervention that is low risk with some small potential benefit,” he said.

The researchers did not evaluate the potential reason for the saline regimen’s association with fewer hospitalizations, but Dr. Rubin said, “It may be possible that nasal saline irrigation and gargling help improve viral clearance and reduce the risk of microaspiration into the lungs, so it may be possible that this intervention could reduce the risk of pneumonia, which is a major cause of hospitalization.”

Dr. Rubin, who is an allergist at Oak Brook Allergists, Ill., said, “I generally recommend nasal saline irrigation to my patients for allergic rhinitis and viral upper respiratory infections already. It can help reduce symptoms such as nasal congestion, rhinorrhea, postnasal drip, and sinus pain and pressure.”

The intervention may be reasonable beyond an adult population, he said.

“This could be used for pediatric patients as well, if they are developmentally ready to try this intervention,” he said.

Mr. Espinoza said further study is warranted, but he said that if confirmed in later trials, the simple intervention may be particularly helpful in low-resource settings.

Mr. Espinoza and Dr. Rubin have disclosed no relevant financial relationships.

ANAHEIM, CALIF. – Patients with uncontrolled asthma are seen more often by primary care providers (PCPs) than by allergists, but a survey has found that 42% of PCPs are unfamiliar with the biologics that have markedly improved asthma treatment options over the past 2 decades.

Bijalben Patel, MD, with the department of internal medicine, University of South Florida, Tampa, said in an interview that in addition to the considerable lack of knowledge of biologics in primary care, she was surprised that 77% of survey participants stated they only referred patients to specialists after two or more exacerbations.

“This is important because these patients are considered to have exacerbation-prone asthma, which should be managed by specialists,” she said.

She said that being “unfamiliar” with biologics meant that the healthcare provider may have heard of biologics but did not know the various types, initiation criteria, or side effects.

The researchers administered a REDCap (Research Electronic Data Capture) survey by email to primary care attending and resident physicians in the departments of internal medicine, family medicine, and pediatrics, and 85 responded. Responses were compared using Chi-square tests.

Patel presented the results of the survey at the annual meeting of the American College of Allergy, Asthma & Immunology.

82% do not order labs

Familiarity did not vary in primary care with number of patients with asthma seen per month, the researchers noted.

“Also, the frequency of PCP referrals to a specialist did not change familiarity with biologics (P = .260) or eligibility criteria (P = .393),” the researchers said.

In addition, they found that 82% of those surveyed do not order labs, and 90% do not use absolute eosinophil count to guide care.

Dr. Patel explained that lab work such as obtaining IgE levels and a complete blood count with a differential and examining the absolute eosinophil count help identify patients who are at high risk for future exacerbation and also treatable phenotypic traits, which can be targeted with biologic therapy. 

Angela Duff Hogan, MD, vice chair of the ACAAI Asthma Committee and professor of pediatrics at Eastern Virginia Medical School, Norfolk, said in an interview that she finds the delay on referrals the most concerning finding in the survey results.

“I’m not as concerned they are not obtaining labs,” said Dr. Hogan, who was not part of the study. “The specialist can do that. It’s more concerning they wait so long to refer a patient with poorly controlled asthma. We know that asthma patients treated by an allergist have better asthma control, better quality of life, and reduced health care costs.”
 

Asthma specialists ‘need better marketing’

Dr. Hogan said that the results show the need for more studies to demonstrate that asthma specialists can improve outcomes and reduce healthcare costs.

“Objective data is more convincing than subjective data,” she noted. “As a specialty, we need to disseminate more information about asthma management, the “new” asthma guidelines, SMART/MART therapy, and the importance of biologicals in asthma. We need better marketing as a specialty in asthma care.”

Dr. Patel said that their goal with the study is to raise awareness about the available asthma biologic therapies, which have been improving care for 2 decades.

“The results of the survey point to the need to improve the communication between primary care physicians and asthma care specialists, including regarding use of biologics,” senior author Juan Carlos Cardet, MD, MPH, also an allergy specialist at USF, added in a press release. “Biologics have become an important tool in the treatment of asthma and other allergic diseases such as atopic dermatitis (eczema), chronic rhinosinusitis with nasal polyps and eosinophilic esophagitis, and can prevent substantial ill results from occurring in patients who are eligible for them.”

The study authors and Dr. Hogan disclosed no relevant financial relationships.

Phytoestrogens show potential as a treatment for menopausal women with late-onset asthma that may relieve symptoms of both conditions, according to a new review.

Fluctuations in female sex steroid hormones during menstrual periods have been linked to asthma exacerbations, and the absence of these hormones during childhood and menopause has been associated with fewer and less severe asthma episodes, wrote Bettina Sommer, PhD, of the Instituto Nacional de Enfermedades Respiratorias, Mexico City, and colleagues.

Late-onset asthma (LOA) has been categorized as a specific asthmatic phenotype that includes menopausal women, and research is needed to explore therapeutic alternatives that might provide relief to older women suffering from LOA, they said.

In a review published in the International Journal of Molecular Sciences, the researchers outlined the potential of phytoestrogens to manage LOA as well as symptoms of menopause.

LOA is often nonatopic and distinguished by a lack of eosinophilic inflammation; it is also associated with obesity and pollutants such as cigarette smoke. LOA is more common in women versus men, and develops between ages 27 and 65 years, the researchers wrote. Very late-onset asthma, which develops in women aged 65 years and older, is related to low levels of total lack of circulating estrogens.

Previous studies have shown that hormone therapy reduces the risk of LOA in menopausal women, but concerns about side effects persist. Phytochemicals offer a low-risk alternative, but phytoestrogen-based hormone therapy and its role in LOA have not been well studied, the researchers wrote.

Estrogen receptors (ERs) have two intracellular isoforms, alpha and beta. “Notably, the literature sustains that ERs expression differs between asthmatics and nonasthmatics,” and mainly the beta ERs are up-regulated in asthma or during inflammations, the researchers said. Phytoestrogens activate ER and benefit postmenopausal women, especially those with asthma, in addition to their anti-inflammatory and antioxidant properties.

Studies using mouse models have shown that E2 phytoestrogen supplementation in mice both increases the expression of antioxidant enzymes and reduces inflammation, according to the researchers. Age-related changes in hormonal statues, immunology, and systemic inflammation may predispose older adults to more infections and asthma exacerbations, but also might drive the development of LOA.

As another example of potential connections between phytoestrogen and asthma, phytoestrogen’s action on an estrogen receptor, notably the beta-ER, was associated with lowered airway hyperresponsiveness in a mouse model, and beta-ER knockout mice showed reduced lung function, compared with wild-type and alpha-ER knockout mice.

More research is needed, but novel therapies using phytoestrogens offer an added advantage to older women with LOA by potentially easing some menopause symptoms with fewer side effects than other options, the researchers wrote. “They may also contribute to more efficient responses to infection and inflammation leading menopausal women to a much better quality of life.”

The study was funded by the Instituto Nacional de Enfermedades Respiratorias, Consejo Nacional de Ciencia y Tecnología, Programa de Apoyo a Proyectos de Investigación e Innovación Tecnológica, and the Universidad Nacional Autonoma de Mexico. The researchers had no financial conflicts to disclose.

Very late-onset asthma, which develops in women aged 65 years and older, is related to low levels of total lack of circulating estrogens.

Previous studies have shown that hormone therapy reduces the risk of LOA in menopausal women, but concerns about side effects persist. Phytochemicals offer a low-risk alternative, but phytoestrogen-based hormone therapy and its role in LOA have not been well studied, the researchers wrote.

Estrogen receptors (ERs) have two intracellular isoforms, alpha and beta. “Notably, the literature sustains that ERs expression differs between asthmatics and nonasthmatics,” and mainly the beta ERs are up-regulated in asthma or during inflammations, the researchers said. Phytoestrogens activate ER and benefit postmenopausal women, especially those with asthma, in addition to their anti-inflammatory and antioxidant properties.

Studies using mouse models have shown that E2 phytoestrogen supplementation in mice both increases the expression of antioxidant enzymes and reduces inflammation, according to the researchers. Age-related changes in hormonal statues, immunology, and systemic inflammation may predispose older adults to more infections and asthma exacerbations, but also might drive the development of LOA.

As another example of potential connections between phytoestrogen and asthma, phytoestrogen’s action on an estrogen receptor, notably the beta-ER, was associated with lowered airway hyperresponsiveness in a mouse model, and beta-ER knockout mice showed reduced lung function, compared with wild-type and alpha-ER knockout mice.

More research is needed, but novel therapies using phytoestrogens offer an added advantage to older women with LOA by potentially easing some menopause symptoms with fewer side effects than other options, the researchers wrote. “They may also contribute to more efficient responses to infection and inflammation leading menopausal women to a much better quality of life.”

The study was funded by the Instituto Nacional de Enfermedades Respiratorias, Consejo Nacional de Ciencia y Tecnología, Programa de Apoyo a Proyectos de Investigación e Innovación Tecnológica, and the Universidad Nacional Autonoma de Mexico.

Phytoestrogens show potential as a treatment for menopausal women with late-onset asthma that may relieve symptoms of both conditions, according to a new review.

Fluctuations in female sex steroid hormones during menstrual periods have been linked to asthma exacerbations, and the absence of these hormones during childhood and menopause has been associated with fewer and less severe asthma episodes, wrote Bettina Sommer, PhD, of the Instituto Nacional de Enfermedades Respiratorias, Mexico City, and colleagues.

Late-onset asthma (LOA) has been categorized as a specific asthmatic phenotype that includes menopausal women, and research is needed to explore therapeutic alternatives that might provide relief to older women suffering from LOA, they said.

In a review published in the International Journal of Molecular Sciences, the researchers outlined the potential of phytoestrogens to manage LOA as well as symptoms of menopause.

Among patients with asthma and comorbid gastroesophageal reflux disease (GERD), the biologic tezepelumab (Tezspire, Amgen) had similar efficacy at reducing exacerbations, improving lung function, and symptom control as observed in patients with asthma alone, according to a new post-hoc analysis of the phase 2b PATHWAY and phase 3 NAVIGATOR clinical trials.

GERD occurs in about 60% of asthma patients, and the comorbidity is associated with a greater risk of asthma exacerbations. “As we start doing subgroup analyses, we are looking at different comorbidities and reflux is one that’s very common and very impactful on asthma outcomes in a negative way, so it became an area of interest,” said Njira Lugogo, MD, who presented the study during a poster session at the annual meeting of the American College of Chest Physicians (CHEST). She is a professor of internal medicine and pulmonary critical care at the University of Michigan, Ann Arbor.

The analysis confirmed other findings, with comorbid GERD associated with more exacerbations, use of maintenance steroids, and high-dose inhaled steroids. “They had more disease activity, and the effect [of tezepelumab treatment] was similar whether you had reflux or didn’t have reflux. It did seem like the people without reflux had a slightly higher reduction in exacerbations, so maybe there is a slight difference, but overall it looked like both groups were really improving,” said Dr. Lugogo.

Tezepelumab is a newer biologic, having received Food and Drug Administration approval in 2021. It targets the epithelial cytokine thymic stromal lymphopoietin (TSLP), which contributes allergic inflammatory responses by acting on various innate immune cells, including dendritic cells, mast cells, and CD34+ progenitor cells. It is upregulated in the airways of asthma patients, with higher levels linked to more severe disease. A single-nucleotide polymorphism in the gene that codes TSLP has also been found to be protective against asthma, atopic asthma, and airway hyper-responsiveness.

Dr. Lugogo noted that TSLP could be a factor in how GERD may worsen trigger or worsen asthma. It is produced in the epithelium of the upper airway in response to injury, which could include aspiration into bronchial tubes attributable to GERD, and this could lead to a downstream inflammatory and immune response. “Reducing the production of or at least blocking TSLP from an epithelium that’s being irritated by acid reflux could have potential benefits. On the reverse side, could the continued presence of reflux blunt the expected response [to tezepelumab]? If someone has very severe reflux, maybe you’ve treated their asthma with tezepelumab, and they’re still having symptoms. Could it be a masquerading issue [where] you have untreated reflux contributing to ongoing symptoms, which you’re attributing to not being related to asthma? So it’s looking at it in two different ways,” said Dr. Lugogo.

TSLP is the only biologic available to treat patients with non–type 2 inflammation, which includes about 10% of adult patients, according to Dr. Lugogo. Its mechanism also influences eosinophilic and allergic asthma. When tezepelumab first became available, Dr. Lugogo noticed that physicians tended to switch to it from another biologic rather than starting it up front, but that may be changing. “I feel like more and more people are starting it up front as a therapeutic intervention, so there seems to be more and more people embracing its use in the treatment of severe asthma,” she said.

The analysis included 294 patients with asthma and GERD and 1,040 with asthma alone. Patients in the GERD comorbidity group were older (55.0 versus 48.6 years), had a higher mean body mass index (30.8 versus 27.8), and were more likely to be female (67.3% versus 63.0%).

Maintenance oral corticosteroid use was higher in the GERD group (17.0% versus 6.9%), as was use of high inhaled corticosteroid dose (78.2% versus 67.0%), frequency of nasal polyps in the previous 2 years (21.4% versus 13.8%), and experience of more than two exacerbations in the previous year (42.2% versus 34.6%).

There was a 65% reduction (95% confidence interval, 50%-76%) in annualized asthma exacerbation rate versus placebo with tezepelumab treatment in the GERD group, compared with a 58% reduction in the asthma-only group (95% CI, 48%-66%). The drug led to a 0.10 increase in forced expiratory volume in 1 second versus placebo (95% CI, 0.00-0.19) at week 52 in the GERD group, versus 0.15 (95% CI, 0.10-0.20) in the asthma-only group. Tezepelumab also improved week 52 ACQ-6 scores in the GERD group (–0.39 versus placebo; 95% CI, –0.63 to –0.14) and the asthma-only group (–0.32 versus placebo; 95% CI, –0.45 to –0.19).

The study adds to the evidence supporting tezepelumab as a promising new therapy, according to Muhammad Adrish, MD, who attended the poster session and was asked to comment on the study. “I think that this is a very interesting analysis in the sense that gastric reflux disease is a frequent comorbid condition that we see in patients with asthma, and a lot of these patients can have poor outcomes. When you look at the results from the data, you see that regardless of how sick they were and how much medication utilization these patients have at baseline, they still had a pretty decent response to tezepelumab. That speaks to the efficacy of that drug along a wide spectrum of patients,” said Dr. Adrish, who is an associate professor of pulmonary, critical care, and sleep medicine at Baylor College of Medicine, Houston.

The PATHWAY and NAVIGATOR studies were funded by Amgen. Dr. Lugogo has advised or consulted for AstraZeneca, Amgen, Regeneron, TEVA, Avillion, Sanofi, Novartis, Genentech, GSK, and Janssen. Dr. Adrish has no relevant financial disclosures.

Endoscopic sinus surgery (ESS) has no significant impact on asthma symptoms for patients with chronic rhinosinusitis up to a year after the procedure, a study of 64 patients shows.

Although ESS is effective in relieving chronic rhinosinusitis, whether it leads to improvement of asthma severity for patients with both conditions remains unclear, Anyull Dayanna Bohórquez Caballero said in a presentation at the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) 2023 annual meeting.

The study “offers a unique approach to explore the effects of endoscopic sinus surgery in a real-world context, with valuable insights that differ from previous research,” Dr. Bohórquez Caballero, an international medical graduate and research fellow of the Mayo Clinic, Jacksonville, Fla., said in an interview.

Under the leadership of senior author Angela Donaldson, MD, Dr. Bohórquez Caballero and colleagues at the Mayo Clinic in Jacksonville analyzed data from 185 adults with both asthma and chronic rhinosinusitis who underwent ESS at the clinic between 2013 and 2023. Asthma severity was evaluated up to 3 months before and 1 year after surgery. Patients’ asthma severity was classified as mild, moderate, or severe on the basis of current Global Initiative for Asthma guidelines using medication requirements.

The final study population included 64 patients; 42 of these (66.7%) had chronic rhinosinusitis with nasal polyps. Outcomes included differences in asthma severity, asthma medication doses, and the number of medications.

Overall, there was no significant difference in measures of mild, moderate, or severe asthma before and after ESS in a McNemar paired test (P values: .130, .999, and .288, respectively). Similarly, no difference was found before and after ESS in terms of total inhaled corticosteroid dose (P = .999), number of medications prescribed (P = .157), or control of the disease (P = .078).

The findings were limited by the relatively small number of patients. The study is the first known to assess the real-world impact of ESS on asthma severity, said Bohórquez Caballero.
 

Expected reduction in asthma severity not seen

Past studies have suggested that ESS improves parameters such as pulmonary function test results or sinonasal outcomes, Dr. Bohórquez Caballero told this news organization. “Our findings indicate that ESS does not significantly impact asthma severity or trends in treatment, including the number and/or dose of medications, in everyday practice.

Our study also identified crucial opportunities to reinforce interdisciplinary follow-up after ESS,” she noted, and it provides a comprehensive depiction of the outcomes experienced by patients with chronic rhinosinusitis and asthma who undergo ESS.

“We were expecting a reduction in severity or a decrease in the dose of inhaled corticosteroid therapies, and we expected to see a translation from previous evidence into clinical practice; however, we did not,” said Dr. Bohórquez Caballero.

“The take-home message is that while there is a strong correlation between CRS and asthma, it does not appear that ESS alone improves real-world treatment based on asthma severity,” she said. “However, our findings have shown that patients may experience a longer period without the need for a reliever medication in the early postoperative period.”

Looking ahead, “We want to explore what happens 5 or 6 months after sinus surgery that would explain the sudden need for a reliever medication,” she added. “Future studies are warranted to investigate the long-term effects of ESS on asthma severity as it relates to modifications of asthma regimens.”
 

Data important for patient discussions

The current study is important because of the frequency of comorbid asthma among patients with chronic rhinosinusitis, Megan Durr, MD, of the University of California, San Francisco, said in an interview.

“When we are considering functional endoscopy sinus surgery with patients, we are often asked if the surgery will impact the severity of their asthma symptoms,” said Dr. Durr, who served as a moderator for the session in which the study was presented.

“I am surprised the study did not see any difference in asthma severity after sinus surgery, as we often talk to patients about the unified airway that refers to the shared epidemiologic and pathophysiologic relationship between the upper and lower airways,” she told this news organization.

“This study will allow us to have a more informed evidenced-based discussion with patients and their primary care providers and/or pulmonologists” about what to expect for asthma outcomes following surgery, she said.

The study received no outside funding. Dr. Durr has disclosed no relevant financial relationships.

“The take-home message is that while there is a strong correlation between CRS and asthma, it does not appear that ESS alone improves real-world treatment based on asthma severity,” she said. “However, our findings have shown that patients may experience a longer period without the need for a reliever medication in the early postoperative period.”

Looking ahead, “We want to explore what happens 5 or 6 months after sinus surgery that would explain the sudden need for a reliever medication,” she added. “Future studies are warranted to investigate the long-term effects of ESS on asthma severity as it relates to modifications of asthma regimens.”
 

Data important for patient discussions

The current study is important because of the frequency of comorbid asthma among patients with chronic rhinosinusitis, Megan Durr, MD, of the University of California, San Francisco, said in an interview.

“When we are considering functional endoscopy sinus surgery with patients, we are often asked if the surgery will impact the severity of their asthma symptoms,” said Dr. Durr, who served as a moderator for the session in which the study was presented.

“I am surprised the study did not see any difference in asthma severity after sinus surgery, as we often talk to patients about the unified airway that refers to the shared epidemiologic and pathophysiologic relationship between the upper and lower airways,” she told this news organization.

“This study will allow us to have a more informed evidenced-based discussion with patients and their primary care providers and/or pulmonologists” about what to expect for asthma outcomes following surgery, she said.

The study received no outside funding. Dr. Durr has disclosed no relevant financial relationships.

Hospitalized patients with both asthma and eosinophilic esophagitis (EoE) were a younger average age than those hospitalized with asthma alone, according to a new analysis of data from HCA Healthcare.

Not much work has been done on the overlap between the two conditions, both of which are believed to be driven by the action of both eosinophils and helper T cells, according to Linda Pham, DO, who presented the research at the annual meeting of the American College of Chest Physicians (CHEST).

“I have a colleague who is interested in GI and he’s really interested in EOE. We thought it would be nice to look at those populations of patients to see if there’s a correlation between them aside from just the atopic disease,” said Dr. Pham, who is an internal medicine resident at Riverside (Calif.) Community Hospital.

The findings underscore the need for assessing individual patient risk. “Having another concomitant disease like EoE, or maybe like atopic dermatitis, might cause you to have more severe [asthma] exacerbations causing you to go into the hospital more. I think if patients have more of these diseases, doctors can be more cognizant that they need to really be on top of treatment and make sure that [their patients] are aware of themselves so that if their symptoms exacerbate, they can go to the hospital and seek care,” said Dr. Pham.

The study was a retrospective analysis of 3,678,812 patients with asthma and 5,823 patients with both EoE and asthma. The data was drawn from 185 HCA hospitals, with records between 2016 and 2021.

The incidence of both asthma and asthma with EoE remained stable between 2016 and 2021. Dr. Pham pointed out that there are good methods to diagnose both conditions, which suggests that existing treatments are effective enough to be limiting the need for emergency treatment, according to Dr. Pham.

Among patients hospitalized with asthma alone, 72.55% were female, while 27.45% were male (P < .001). The numbers were much more evenly split among those with asthma and EoE, at 51.78% and 48.22%, respectively. The differing gender statistics aren’t easy to explain. “It’s not quite clear whether it’s because they just have more severe symptoms, or if it is other factors causing women to seek care more than their male counterparts. It could be personal biases, or it could be the asthma itself that is more severe in women,” said Dr. Pham.

When they broke down the analysis by sex, the researchers found that male EoE patients without asthma were a mean value of 5.517 years older than male EoE patients with asthma, and the mean difference was 5.480 years in female patients (P < .001 for both).

Although the direct cause of earlier hospitalization among patients with concomitant EoE and asthma is unclear, Dr. Pham speculated that the combination of atopic diseases may be leading to a stronger inflammatory response.

It remains to be seen if a similar relationship occurs with other atopic diseases, and future research could examine other factors. “I think it’d be good to look at not just age and gender, but BMI and occupation, things like that,” said Dr. Pham.

The study was of particular interest to Michelle Robertson, MD, who was in the audience. She is the director for clinical services at the Airborne Hazards and Burn Pits Center of Excellence at the New Jersey War-Related Illness and Injury Study Center. “We see a significant number of [veterans] who have been diagnosed with both asthma and eosinophilic esophagitis, and our thinking is that that is likely related to some of the military exposures: In particular, [what the] deployed veterans encountered in the Gulf War, [such as] the smoke from burn pits, sand and dust storms, and smoke from oil well fires. Our thinking is that the particulate matter, the PM 2.5, the very, very tiny particles, may be either sensitizing the lung area and/or esophagus and predisposing them to having those symptoms when they return home,” said Dr. Robertson, in an interview.

Particles in this size range may be able to bypass the protected areas of the nose and the lungs to reach the alveoli, where they could potentially interfere with the transfer of air between the lungs and the rest of the body, which could in turn lead to a variety of inflammatory conditions, according to Dr. Robertson.

She noted that particle exposure varies with a soldier’s wartime occupation, with higher exposures among mechanics and burn pit managers, for example. However, the highest levels of exposure do not predict later illness, which is a natural prompt for future research. “The second part of this whole pathophysiology is susceptibility. Is there something about those people that do get sick that makes them more susceptible than folks that don’t, even though they both have the same jobs?”

Dr. Pham and Dr. Robertson have no relevant financial disclosures.

HONOLULU – Sexual and gender minority (SGM) people are at increased risk for asthma severity, compared with non-SGM people, and asthma is especially exacerbated in SGM persons who use e-cigarettes compared with heterosexuals.

These findings come from a study of asthma severity among SGM people, with a special focus on the contribution of tobacco, reported Tugba Kaplan, MD, a resident in internal medicine at Luminis Health Anne Arundel Medical Center, Annapolis, Md.

“To the best of our knowledge, this is the first study assessing asthma severity among SGM people in a nationally representative longitudinal cohort study,” she said in an oral abstract session at the annual meeting of the American College of Chest Physicians (CHEST).

There has been only limited research on the health status and health needs of SGM people, and most of the studies conducted have focused on issues such as HIV/AIDS, sexual health, and substance use, not respiratory health, she said.
 

Following the PATH

Dr. Kaplan and colleagues drew on data from the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative longitudinal cohort study with data on approximately 46,000 adults and adolescents in the United States.

The study uses self-reported data on tobacco use patterns; perceptions of risk and attitudes toward tobacco products; tobacco initiation, cessation, and relapse; and associated health outcomes.

The investigators combined data from three waves of the PATH Study, conducted from 2015 to 2019 on nonpregnant participants aged 18 years and older, and used mixed-effect logistic regression models to look for potential associations between sexual orientation and asthma severity.

They used standard definitions of asthma severity, based on lung function impairment measured by forced expiratory volume in 1 second and forced vital capacity, nighttime awakenings, use of a short-acting beta2-agonist for symptoms, interference with normal activity, and exacerbations requiring oral systemic corticosteroids.

The study also includes a sexual orientation question, asking participants, “do you consider yourself to be ...” with the options “straight, lesbian or gay, bisexual, something else, don’t know, or refused.”

Based on these responses, Dr. Kaplan and colleagues studied a total sample of 1,815 people who identify as SGM and 12,879 who identify as non-SGM.
 

Risks increased

In an analysis adjusted for age, sex, race/ethnicity, tobacco use, body mass index, physical activity, and asthma medication use, the authors found that, compared with non-SGM people, SGM respondents were significantly more likely to have had asthma attacks requiring steroid use in the past years (odds ratio, 1.47; 95% confidence interval, 1.01-2.15), asthma interfering with daily activities in the past month (OR, 1.33; CI, 1.10-1.61), and shortness of breath in any week over the 30 days (OR, 1.82; CI, 1.32-2.51). There was no significant difference between the groups in inhaler use over the past month, however.

They also found two interactions in the logistic regression models, one between urgent care visits and respondents who reported using both regular tobacco and e-cigarettes (dual users), and between exclusive e-cigarette use and waking up at night.

Among dual users, SGM respondents had a nearly fourfold greater risk for asthma attacks requiring urgent care visits, compared with non-SGM respondents (OR, 3.89; CI, 1.99-7.63). In contrast, among those who never used tobacco, there were no significant differences between the sexual orientation groups in regard to asthma attacks requiring urgent care visits.

Among those who reported using e-cigarettes exclusively, SGM respondents were nearly eight times more likely to report night awakening, compared with non-SGM users (OR, 7.81; CI, 2.93-20.8).

Among never users, in contrast, there was no significant difference in nighttime disturbances.
 

Possible confounders

The data suggest that “in the context of chronic illnesses like asthma, it is crucial to offer patients the knowledge and tools required to proficiently handle their conditions,” Dr. Kaplan said, adding that the differences seen between SGM and non-SGM respondents may be caused by health care disparities among SGM people that result in nonadherence to regular follow-ups.

In an interview, Jean Bourbeau, MD, MSc, who was a moderator for the session but was not involved in the study, commented that “we have to be very careful before making any conclusions, because this population could be at high risk for different reasons, and especially, do they get the same attention in terms of the care that is provided to the general population, and do they get access to the same medication?”

Nonetheless, Dr. Bourbeau continued, “I think this study is very important, because it shows us how much awareness we need to determine differences in populations, and [sexual orientation] is probably one thing that nobody had considered before, and for the first time we are now considering these potential differences in our population.”

The authors did not report a study funding source. Dr. Kaplan and Dr. Bourbeau reported having no relevant financial relationships.

In a real-world study of asthma patients, treatment with biologics following an exacerbation was associated with better health care utilization outcomes.

The data fill a gap, according to Sushan Gupta, MD, who presented the results at the annual meeting of the American College of Chest Physicians. “There’s some ample real-world data that shows that biologics reduce the incidence of asthma exacerbation, but the data regarding what happens after an exacerbation is still lacking, especially real-world data,” said Dr. Gupta, who is a resident at Carle Foundation Hospital in Champaign, Ill.

The findings were encouraging. “Patients with severe asthma on biologics fare well even after an exacerbation event, which includes a reduced incidence of hospitalization, ICU admission, and need for mechanical ventilation. We did not have any patient in the biologic group that required intubation, so that is pretty significant as compared to other patients who did not receive biologics,” said Dr. Gupta.

The results weren’t surprising, but underscore the benefits of biologics, according to Brittany Duchene, MD, who moderated the session where the results were presented. “I think it reinforced that they’re really good drugs,” said Dr. Duchene, who is a pulmonary critical care physician at Northeastern Vermont Regional Hospital, St. Johnsbury.

Although the study was retrospective, it suggests that the threshold for initiating biologics could potentially be lowered for patients with uncontrolled asthma despite adequate use of inhalers, according to Dr. Gupta. “Should that threshold be lower, and would that improve the overall morbidity and eventually the health care cost of utilization? Our study does not prove any of those data, but moving forward that data will also come out.”

Dr. Duchene noted that the accumulating scientific and clinical data for biologics is “really, really strong.” She also speculated that biologics could be used increasingly in the acute setting, which she admitted is a controversial topic. “I think there’s going to be a lot more push to early initiation, and you can see from the [new] study that it decreased a lot of hospitalizations.”

Dr. Gupta emphasized the need for prospective studies, and Dr. Duchene agreed that any such change would need to be patient centric, considering the diversity of available biologics. “It depends what their true issue is. The broader the biologic [mechanism of action], probably the more success you’ll have. I’ve found there’s not a pure allergic or a pure eosinophilic asthma patient. They’re usually more a combination.”

Some key questions remain about biologics treatment, especially in the long term. These include when a patient should be switched from one biologic to another, and whether biologic treatment should be continued over the patient’s lifetime and potential long-term side effects. “I think that data is still evolving and will come to us with time,” said Dr. Gupta.

The researchers analyzed retrospective data from 316 asthma patients treated with biologics and 9,645 treated with nonbiologic therapy between February 2018 and February 2023 at a tertiary care teaching hospital in the Midwest. There was a higher proportion of females in the biologics (69.7%) and nonbiologics groups (63.8%, P = .032), but there was no significant difference in the proportion of Whites in the biologics and nonbiologics groups (78.2% vs. 74.3%, P = .103).

The lack of a difference in racial groups was a surprise, according to Dr. Duchene, especially since other studies have noted disparities in biologic therapy among asthma patients.

Among the biologics group, 0.9% were hospitalized during the study period, compared with 6.5% of the nonbiologics group (P = .00006). They also had fewer ICU visits (0.3% vs. 1.8%; P = .04).

Dr. Gupta’s team attempted to subdivide the data by individual biologic, but there was no statistical significance in outcomes between biologics, perhaps because of the relatively small sample size.

Dr. Gupta noted that his group’s results are generally similar to other studies, including a U.S. study that found a decrease in exacerbation rates after staring or switching biologics and a slightly higher prevalence of biologics use among White patients (77% of biologic users versus 71% of nonbiologics users). A study in southwestern England found fewer ED visits and hospitalizations among patients on biologics.

In a real-world study of asthma patients, treatment with biologics following an exacerbation was associated with better health care utilization outcomes.

The data fill a gap, according to Sushan Gupta, MD, who presented the results at the annual meeting of the American College of Chest Physicians. “There’s some ample real-world data that shows that biologics reduce the incidence of asthma exacerbation, but the data regarding what happens after an exacerbation is still lacking, especially real-world data,” said Dr. Gupta, who is a resident at Carle Foundation Hospital in Champaign, Ill.

The findings were encouraging. “Patients with severe asthma on biologics fare well even after an exacerbation event, which includes a reduced incidence of hospitalization, ICU admission, and need for mechanical ventilation. We did not have any patient in the biologic group that required intubation, so that is pretty significant as compared to other patients who did not receive biologics,” said Dr. Gupta.

The results weren’t surprising, but underscore the benefits of biologics, according to Brittany Duchene, MD, who moderated the session where the results were presented. “I think it reinforced that they’re really good drugs,” said Dr. Duchene, who is a pulmonary critical care physician at Northeastern Vermont Regional Hospital, St. Johnsbury.

Although the study was retrospective, it suggests that the threshold for initiating biologics could potentially be lowered for patients with uncontrolled asthma despite adequate use of inhalers, according to Dr. Gupta. “Should that threshold be lower, and would that improve the overall morbidity and eventually the health care cost of utilization? Our study does not prove any of those data, but moving forward that data will also come out.”

Dr. Duchene noted that the accumulating scientific and clinical data for biologics is “really, really strong.” She also speculated that biologics could be used increasingly in the acute setting, which she admitted is a controversial topic. “I think there’s going to be a lot more push to early initiation, and you can see from the [new] study that it decreased a lot of hospitalizations.”

Dr. Gupta emphasized the need for prospective studies, and Dr. Duchene agreed that any such change would need to be patient centric, considering the diversity of available biologics. “It depends what their true issue is. The broader the biologic [mechanism of action], probably the more success you’ll have. I’ve found there’s not a pure allergic or a pure eosinophilic asthma patient. They’re usually more a combination.”

Some key questions remain about biologics treatment, especially in the long term. These include when a patient should be switched from one biologic to another, and whether biologic treatment should be continued over the patient’s lifetime and potential long-term side effects. “I think that data is still evolving and will come to us with time,” said Dr. Gupta.

The researchers analyzed retrospective data from 316 asthma patients treated with biologics and 9,645 treated with nonbiologic therapy between February 2018 and February 2023 at a tertiary care teaching hospital in the Midwest. There was a higher proportion of females in the biologics (69.7%) and nonbiologics groups (63.8%, P = .032), but there was no significant difference in the proportion of Whites in the biologics and nonbiologics groups (78.2% vs. 74.3%, P = .103).

The lack of a difference in racial groups was a surprise, according to Dr. Duchene, especially since other studies have noted disparities in biologic therapy among asthma patients.

Among the biologics group, 0.9% were hospitalized during the study period, compared with 6.5% of the nonbiologics group (P = .00006). They also had fewer ICU visits (0.3% vs. 1.8%; P = .04).
