COPD: Large-scale study suggests protective role for vitamin D
BMJ Open Respiratory Research.
COPD risk was 23% higher in people within the lowest quintile vs. the fourth quintile of 25(OH)D concentrations, according to research appearing inWhile low vitamin D status has been linked to increased inflammatory diseases risk and to the regulation of pathogenic mechanisms in COPD, epidemiological evidence regarding the associations of 25(OH)D concentrations with COPD incidence and survival remains inconclusive, Zheng Zhu, MD, of Jiangsu Provincial Center for Disease Control and Prevention, Nanjing, China, and colleagues wrote.
From UK Biobank data recorded from 403,648 participants (mean age 56.4 years; 54% women) who were free of COPD at baseline and had 25(OH)D measurements, researchers estimated hazard ratios and 95% confidence intervals for the associations of 25(OH)D concentrations with COPD risk and survival. After median follow-up of 12.3 years (ending Sept. 30, 2021), with 11,008 COPD cases recorded, beyond the COPD and mortality increase (HR, 1.23; 95% CI, 1.16-1.31) in the lowest quintile of 25(OH)D concentrations, risk for overall death was 38% higher, as well (HR, 1.38; 95% CI, 1.22-1.56). Serum concentrations were greater than 64.6 nmol/L in the highest (quintile 5) and less than 31.7 nmol/L in the lowest (quintile 1). Also, men and current smokers had higher COPD and mortality risk (P interaction for both: < .05).
While event rates tracked generally inversely with 25(OH)D concentrations, overall the event curves were non-linear. Dr Zhu and associates reported that the decreasing risk of COPD appeared to be lowest at 55 nmol/L of 25(OH)D within quintile 4 (51.8 to < 64.6 nmol/L). Furthermore, lower prediagnostic 25(OH)D concentrations were associated with a significant decrease in overall and COPD-specific survival.
Smoking is the most commonly encountered risk factor for COPD, the researchers noted, and their findings indicated that 25(OH)D concentrations were inversely associated with COPD risk in both smokers and never-smokers. In a fully adjusted model, compared with quintile 4, the quintile 1 increase in COPD risk was 25% in never-smokers and 23% in smokers.
“Our findings imply that vitamin D might play a role in progression of COPD,” the authors stated. They added, “Whether lower concentrations of 25(OH)D are causal or contributory to COPD risk may spur future long-duration and large-scale RCTs.”
“Vitamin D has an important function in the immune system and lower serum levels have been implicated in a variety of inflammatory diseases,” commented associate professor of medicine Diego J. Maselli, MD, who is chief of the division of pulmonary diseases & critical care at UT Health San Antonio. “Patients with COPD often have lower levels of vitamin D compared to healthy individuals. COPD patients with low serum levels of vitamin D may have a higher risk of exacerbations and worse lung function.”
He added, “The research by Zhu and colleagues adds to the field of study and highlights the potential role of vitamin D in the pathophysiology of COPD. It is important to remember that these associations do not establish causality, as patients with chronic and debilitating diseases may have limited sunlight exposure, poor nutritional intake, and other behaviors that may affect vitamin D levels. There are mixed results in studies evaluating the role of supplementing vitamin D in COPD with regards to disease progression and exacerbation reduction. While there are some studies that report that supplementation of vitamin D can reduce COPD exacerbations, there is still a need for randomized controlled studies that explore if the supplementation of vitamin D can prevent the development of COPD, particularly in those who actively smoke. Yet, it is reasonable to evaluate the serum vitamin D levels in COPD patients who have had exacerbations and supplement when there is a severe deficiency.”
Given that the majority of participants in this study were from the United Kingdom, the researchers stated, a study limitation is that findings might not apply to other populations.
No disclosures were reported by Dr. Zhu or by Dr. Maselli.

Pneumococcal vaccine label adds injection-site risk
No similar safety signal has been detected for the more recently approved 15-valent and 20-valent pneumococcal conjugate vaccines, explain the investigators, led by Brendan Day, MD, MPH, from the FDA’s Center for Biologics Evaluation and Research, in their report published online in JAMA Internal Medicine.
Reports of injection-site necrosis emerged after the vaccine (Pneumovax 23, Merck) had been approved by the FDA and was administered to a large, diverse, real-world population.
Rare safety events can emerge after FDA approval, as clinical trials may not be able to detect them in a study-group population.
Therefore, “postmarketing safety surveillance is critical to further characterize the safety profile of licensed vaccines,” the investigators point out.
The FDA and the Centers for Disease Control and Prevention monitor the postmarketing safety of licensed vaccines using the Vaccine Adverse Event Reporting System (VAERS), which relies on people who get the vaccines to report adverse events.
Real-world finding
After reports indicated a safety signal in 2020, the researchers conducted a case-series review, calculated the reporting rate, and did a PubMed search for similar reports.
They found that the reporting rate for injection-site necrosis was less than 0.2 cases per 1 million vaccine doses administered. The PubMed search yielded two cases of injection-site necrosis after the vaccine.
The 23-valent vaccine helps protect people from pneumococcus bacterial infection. The manufacturer reports that it is for people at least 50 years of age and for children who are at least 2 years of age with medical conditions that put them at elevated risk for infection.
The U.S. package insert has been updated, in the Post-Marketing Experience section, to include injection-site necrosis.
Of the 104 VAERS reports identified by the researchers, 48 met the case definition. Of those cases, most were for skin necrosis (n = 43), five of which also included fat necrosis. The remaining five cases of necrosis affected fascia (n = 2); fat and fascia (n = 1); fat, fascia, and muscle (n = 1); and muscle (n = 1).
In 23 of the 48 cases (47.9%), the reactions were serious and included one death (unrelated to vaccination).
Seventeen patients (35.4%) were hospitalized and 26 (54.2%) required surgery, most commonly debridement. Eight patients (16.7%) underwent multiple surgical procedures and three (6.3%) required a skin graft.
For patients with skin necrosis (n = 43), the median age was 67 years, and most patients were female (n = 36). Twelve patients were immunocompromised.
Concomitant vaccinations were reported in 10 patients, five of whom got the shot in the same arm as the 23-valent pneumococcal vaccine. A concurrent diagnosis of cellulitis was reported in 16 patients and an abscess was reported in three patients. There were too few cases of fat, fascia, or muscle necrosis to draw conclusions, the researchers report.
Often, skin necrosis was seen after a progression of symptoms, such as redness, pain, or swelling.
“These reports are consistent with published descriptions of injection-site necrosis, which has been reported as a rare complication for many vaccines and injectable drugs,” the investigators report.
Although the researchers couldn’t conclude from the VAERS reports alone that the vaccine injection caused the necrosis, “the timing and the location of reactions at the injection site suggest a possible causal association with the vaccine,” they explain. However, they add, patient comorbidities and poor injection technique may also be contributors.

FDA approves RSV monoclonal antibody for all infants
The monoclonal antibody Beyfortus (nirsevimab-alip), which already is approved for use in Europe and Canada, is indicated for newborns and infants born during or entering their first RSV season, and for children up to 24 months of age who are vulnerable to severe RSV through their second RSV season.
As many as 80,000 children under age 5 years are hospitalized with an RSV infection annually in the United States. Most cases are mild, but infants under 6 months, those born prematurely, and children with weakened immune systems or neuromuscular disorders are at an increased risk for severe illness, according to the Centers for Disease Control and Prevention.
The highly contagious virus is also a concern for immunocompromised adults and older people with underlying health conditions, who are at increased risk for severe disease.
Sanofi and AstraZeneca, which jointly developed the injectable agent, said in a press release that the companies plan to make it available by the fall of 2023. The long-acting antibody is given as a single intramuscular injection.
Beyfortus was approved in part based on data from the phase 3 MELODY trial, which found the shot reduced the incidence of medically attended lower respiratory tract infections associated with RSV by 74.9% versus placebo (95% confidence interval, 50.6-87.3; P < .001).
The phase 2/3 MEDLEY trial, conducted between July 2019 and May 2021, compared Beyfortus with palivizumab, another RSV antibody injection with more limited indications. The trial included more than 900 preterm infants less than 35 weeks’ gestational age and infants with congenital heart disease. Results were similar to the phase 3 MELODY trial, according to the manufacturers.
“Today’s approval marks an unprecedented moment for protecting infant health in the United States, following an RSV season that took a record toll on infants, their families, and the U.S. health care system,” said Thomas Triomphe, executive vice president for vaccines at Sanofi, in a press release about the FDA decision. “Beyfortus is the only monoclonal antibody approved for passive immunization to provide safe and effective protection for all infants during their first RSV season.”

LAMA-LABA surpasses corticosteroid combination as COPD therapy
Use of inhalers with long-acting muscarinic antagonists and long-acting beta-agonists reduced COPD exacerbations and pneumonia hospitalizations compared with inhalers with corticosteroids and long-acting beta-agonists, based on data from more than 30,000 individuals.
Current clinical guidelines for chronic obstructive pulmonary disease (COPD) patients recommend inhalers with long-acting muscarinic antagonists (LAMAs) and long-acting beta-agonists (LABAs) over those with inhaled corticosteroids (ICSs) and LABAs, but data comparing the two formulations have been inconsistent, and concerns about generalizability persist, wrote William B. Feldman, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
In a study published in JAMA Internal Medicine, the researchers reviewed data from a commercial insurance claims database of individuals diagnosed with COPD who filled a new prescription for a LAMA-LABA inhaler or ICS-LABA inhaler between Jan. 1, 2014, and Dec. 31, 2019. Patients with asthma and those younger than 40 years were excluded. The study population included 137,833 individuals with a mean age of 70.2 years; 50.4% were female. Of the 107,004 ICS-LABA users and 30,829 LAMA-LABA users, 30,216 matched pairs were included in a 1:1 propensity score matched study. The primary outcomes were effectiveness, based on the rate of first moderate or severe COPD exacerbation, and safety, based on the rate of first pneumonia hospitalization.
Use of LAMA-LABA inhalers was associated with an 8% reduction in the rate of first moderate or severe COPD exacerbation and a 20% reduction in the rate of first pneumonia hospitalization compared with use of ICS-LABA (hazard ratios 0.92 and 0.80, respectively). The absolute rate reductions with LAMA-LABA inhalers for first moderate or severe COPD exacerbations and for first pneumonia hospitalizations were was 43.0 events per 1,000 person-years and 91.8 events per person-years, respectively.
The overall rates of total moderate to severe COPD and pneumonia hospitalizations were 5% and 17% lower, respectively, among patients who used LAMA-LABA than those treated with ICS-LABA. The results were consistently robust in subgroup and sensitivity analyses, the researchers wrote in their discussion. However, the results must be interpreted cautiously in comparison to other large studies because of the significant differences in the cohorts of patients studied, notably that most patients in the current study had no received previous inhaler therapy.
The study findings were limited by several factors including the relatively short follow-up time and reliance on prescription fills as an indicator of medication use, the researchers noted. Other limitations included notable differences between the LAMA-LABA patients and ICS-LABA patients, such as more severe COPD and less access to respiratory care, they wrote.
Although the current study is not the definitive answer to conflicting results from previous trials, it is the largest know to date to compare LAMA-LABA with ICS-LABA, and the results support LAMA-LABA as the preferred therapy for COPD patients, the researchers concluded.
Findings clarify clinical practice guidelines
“This study was required to provide clarity regarding the optimal choice of treatment for COPD given conflicting data from other recent trials,” Suman Pal, MBBS, of the University of New Mexico, Albuquerque, said in an interview.
“The study findings reinforce the benefits of combined LAMA-LABA in improving clinical outcomes in COPD in a real-world setting,” and the data provide further support for choosing LAMA-LABA over ICS-LABA in COPD patients, said Dr. Pal, who was not involved in the study.
However, availability and affordability of LAMA-LABA inhalers may be barriers to expanding their use in clinical practice, he noted.
“Additional research is needed to accurately define which patient populations would benefit most from the therapy and whether patients who have previously been stabilized on ICS-LABA would derive additional benefit from a change in therapy,” Dr. Pal said.
The study was supported by the National Heart, Lung, and Blood Institute and funding from the Commonwealth Fund and Arnold Ventures.
Dr. Feldman disclosed receiving personal fees from Alosa Health and Aetion, serving as an expert witness in litigation against inhaler manufacturers, and receiving an honorarium for a presentation to Blue Cross Blue Shield of Massachusetts unrelated to the current study. Dr. Pal had no financial conflicts to disclose.

In a study published in JAMA Internal Medicine, the researchers reviewed data from a commercial insurance claims database of individuals diagnosed with COPD who filled a new prescription for a LAMA-LABA inhaler or ICS-LABA inhaler between Jan. 1, 2014, and Dec. 31, 2019. Patients with asthma and those younger than 40 years were excluded. The study population included 137,833 individuals with a mean age of 70.2 years; 50.4% were female. Of the 107,004 ICS-LABA users and 30,829 LAMA-LABA users, 30,216 matched pairs were included in a 1:1 propensity score matched study. The primary outcomes were effectiveness, based on the rate of first moderate or severe COPD exacerbation, and safety, based on the rate of first pneumonia hospitalization.
Use of LAMA-LABA inhalers was associated with an 8% reduction in the rate of first moderate or severe COPD exacerbation and a 20% reduction in the rate of first pneumonia hospitalization compared with use of ICS-LABA (hazard ratios 0.92 and 0.80, respectively). The absolute rate reductions with LAMA-LABA inhalers for first moderate or severe COPD exacerbations and for first pneumonia hospitalizations were was 43.0 events per 1,000 person-years and 91.8 events per person-years, respectively.
The overall rates of total moderate to severe COPD and pneumonia hospitalizations were 5% and 17% lower, respectively, among patients who used LAMA-LABA than those treated with ICS-LABA. The results were consistently robust in subgroup and sensitivity analyses, the researchers wrote in their discussion. However, the results must be interpreted cautiously in comparison to other large studies because of the significant differences in the cohorts of patients studied, notably that most patients in the current study had no received previous inhaler therapy.
The study findings were limited by several factors including the relatively short follow-up time and reliance on prescription fills as an indicator of medication use, the researchers noted. Other limitations included notable differences between the LAMA-LABA patients and ICS-LABA patients, such as more severe COPD and less access to respiratory care, they wrote.
Although the current study is not the definitive answer to conflicting results from previous trials, it is the largest know to date to compare LAMA-LABA with ICS-LABA, and the results support LAMA-LABA as the preferred therapy for COPD patients, the researchers concluded.
Findings clarify clinical practice guidelines
“This study was required to provide clarity regarding the optimal choice of treatment for COPD given conflicting data from other recent trials,” Suman Pal, MBBS, of the University of New Mexico, Albuquerque, said in an interview.
“The study findings reinforce the benefits of combined LAMA-LABA in improving clinical outcomes in COPD in a real-world setting,” and the data provide further support for choosing LAMA-LABA over ICS-LABA in COPD patients, said Dr. Pal, who was not involved in the study.
However, availability and affordability of LAMA-LABA inhalers may be barriers to expanding their use in clinical practice, he noted.
“Additional research is needed to accurately define which patient populations would benefit most from the therapy and whether patients who have previously been stabilized on ICS-LABA would derive additional benefit from a change in therapy,” Dr. Pal said.
The study was supported by the National Heart, Lung, and Blood Institute and funding from the Commonwealth Fund and Arnold Ventures.

Spirometry predicts mortality in type 2 diabetes
Among adults with type 2 diabetes, the presence of preserved ratio impaired spirometry (PRISm) was significantly associated with increased risk of mortality and both macro- and microvascular complications, as well as increased mortality, based on data from more than 20,000 individuals.
“A growing number of studies have demonstrated that impaired lung function and type 2 diabetes could trigger shared pathophysiological injuries, such as microangiopathy and chronic inflammation,” they said, but the potential role of PRISm as an early predictor of adverse outcomes in patients with type 2 diabetes has not been fully examined.
In a study published in the journal Chest, the researchers reviewed data from 20,047 individuals with type 2 diabetes in the UK Biobank, a population-based cohort of adults aged 37-73 years recruited between 2006 and 2010.
The main exposure was lung function based on spirometry. PRISm was defined as predicted forced expiratory volume per second (FEV1) less than 80%, with an FEV1/ forced vital capacity (FVC) ratio of at least 0.70. Individuals with normal spirometry (defined as predicted FEV1 ≥ 80% with an FEV1/FVC ratio ≥ 0.70) served as controls.
The primary outcomes were major complications of type 2 diabetes including macrovascular events (myocardial infarction, unstable angina, coronary heart disease [CHD], ischemic stroke, and any type of stroke), microvascular events (diabetic retinopathy and diabetic kidney disease) and mortality (all-cause, cardiovascular, and respiratory).
Overall, 16.9% of study participants (3385 patients) had obstructive spirometry and 22.6% (4521 patients) had PRISm. Compared with individuals with normal spirometry, those with PRISm were more likely to be current smokers, obese, and living in economically disadvantaged areas. Individuals with PRISm also were significantly more likely to be long-term patients with diabetes who were taking glucose-lowering or lipid-lowering drugs (P < .001 for all).
The median follow-up for each of the type 2 diabetes complications and mortality was approximately 12 years. Over this time, 5.0% of patients developed incident MI, 1.3% developed unstable angina, 15.6% had CHD, 3.5% had an ischemic stroke, and 4.7% had any type of stroke. As for microvascular events, 7.8% developed diabetic retinopathy and 6.7% developed diabetic kidney disease. A total of 2588 patients died during the study period (15.1%), including 544 from cardiovascular disease and 319 from respiratory disease.
PRISm was significantly associated with increased risk of each of the complications and mortality types. These associations persisted after adjusting for lifestyle and other factors. The fully adjusted hazard ratios for PRISm versus normal spirometry were 1.23 for MI, 1.23 for unstable angina, 1.21 for CHD, 1.38 for ischemic stroke, 1.41 for any type of stroke, 1.31 for diabetic retinopathy, and 1.38 for diabetic kidney disease. Adjusted HRs for mortality were 1.34, 1.60, and 1.56 for all-cause, cardiovascular, and respiratory mortality, respectively.
The researchers also found that adding PRISm to an office-based risk score significantly improved the risk classification and predictive power for type 2 diabetes complications with the exception of unstable angina and mortality. They found little evidence for an association with sex, smoking, or PRISm duration and any mortality types. However, in subgroup analyses by age, sex, and duration of diabetes, PRISm remained associated with increased risk of macrovascular and microvascular complications, as well as mortality.
Potential mechanisms for the association between PRISm and diabetes complications include the role of insulin resistance in the exacerbation of lung damage in patients with type 2 diabetes, the increased rate of supplemental oxygen use among individuals with PRISm, and the increased prevalence of pulmonary artery enlargement in the PRISm subjects, the researchers wrote.
The findings were limited by several factors including the prospective design, the homogeneous population of individuals primarily of British or Irish ancestry, and the exclusion of diabetic neuropathy from the analysis, the researchers noted.
However, the results were strengthened by the large cohort, use of professional spirometry, and relatively long follow-up. “The findings underscore the relevance of PRISm for prognostic classification in type 2 diabetes and its potential for optimizing prevention strategies in this condition,” they concluded.
The study was supported by the National Natural Science Foundation of China, Natural Science Foundation of Jiangsu Province, and the Priority Academic Program Development of Jiangsu Higher Education Institutions. The researchers reported no relevant financial relationships.

Parsing the split-decision victory for biologics in COPD
It’s tough to keep up with the proliferation of monoclonal antibodies. Seems every day I’m confronted by a patient who’s using a new drug with a name ending in “mab.” That drug blocks a cellular receptor I haven’t heard of that’s involved in a cascade of interactions I haven’t thought about since medical school. The resulting disruption reduces disease burden, typically at great expense to the medical system, the patient, or both. We’ve truly entered the era of precision medicine. It’s not enough to understand disease; you also must know its heterogeneous expression so that you can prescribe the ‘mab that targets the biology responsible for variants in behavior. All diseases are, in fact, syndromes. This isn’t a bad thing, but it’s a challenge.
A series of ‘mabs have been approved for treating type 2 high (TH2) or eosinophilic asthma. We refer to this group of ‘mabs generically as biologics. The group includes omalizumab, mepolizumab, dupilumab, benralizumab, reslizumab, and tezepelumab. While mechanism of action varies slightly across drugs, the biologics all target a specific arm of the immune system. Efficacy is linearly related to serum eosinophil count and there’s little clinically or pharmacologically to distinguish one from another. Of course, no head-to-head comparisons of efficacy are available and there’s no financial incentive for them to be performed.
Latest research
A new randomized controlled trial (RCT) of dupilumab for chronic obstructive pulmonary disease (COPD) adds to the aforementioned biologic knowledge base. Turns out it works as long as the patients are carefully selected. Researchers enrolled GOLD D (or E depending on which iteration of the GOLD Statement you use) patients on triple inhaler therapy (inhaled corticosteroids [ICS]/long-acting beta-agonist [LABA]/long-acting muscarinic antagonist [LAMA]) with two moderate exacerbations or one exacerbation requiring hospitalization in the past year. Blood eosinophil counts were > 300 cells/mcL and chronic bronchitis was present clinically. The primary and multiple secondary outcomes were improved with dupilumab.
This is welcome news. I’ve treated countless patients with severe COPD who have repeated exacerbations despite my efforts to prevent them. These patients are on ICS/LABA/LAMA and azithromycin or roflumilast, and occasionally both. While every COPD guideline known to man forbids using chronic oral corticosteroids (OCS), I’ve prescribed them repeatedly because the benefits to keeping a recalcitrant, exacerbating patient out of the hospital seem to outweigh OCS risks. It would be nice to have a better option. Although we were taught that they were immutably distinct in medical school, every first-year pulmonary fellow knows that asthma and COPD share more similarities than differences, so it makes sense that proven asthma therapies would work for some patients with COPD.
However, the dupilumab study must be placed in context. Past studies haven’t been as positive. In 2017, two separate RCTs found that mepolizumab reduced the annual rate of moderate to severe exacerbations (primary outcome) in one trial but not the other. Interpretation gets more complicated when broken down by intention to treat (ITT) vs. modified ITT and when secondary outcomes are considered. Sparing you those details, this trial does not instill confidence, leading the Food and Drug Administration to refuse approval for mepolizumab for COPD. A second RCT of benralizumab for COPD was published in 2019. Much less cognitive load was required to interpret this one; it was negative. FDA approval was not requested.
Looking through the trial designs for the three RCTs of biologics for COPD, I couldn’t find major differences that could explain the discordant results. Sample size and enrollment criteria were similar. As stated, I don’t believe that the biologic data in asthma allow for predicting efficacy in one eosinophilic patient vs. another and I assume the same would be true for COPD. All three trials found that eosinophils were eliminated, so responses were biologically equivalent.
Key takeaways
If trial design and pharmacology don’t account for the disparate outcomes, how do we explain them? More important, how do we translate these trials into clinical practice? I looked for a review or editorial by a scientist-clinician smarter than I so I could steal their ideas and express them as pedantic euphemisms here. I found it curious that I was unable to find one. A recent publication in the American Journal of Respiratory and Critical Care Medicine suggests that the answer lies within the complex lattice of eosinophil subtypes, but I’m unqualified to judge the veracity of this “phenotype within a phenotype” theory.
More trials in COPD are being done. We should have results on tezepelumab, that great savior that may cover noneosinophilic asthma phenotypes, within the next few years. Until then, we’re stuck defying guidelines with the anachronistic use of OCS for the COPD patient who exacerbates through ICS/LABA/LAMA, roflumilast, and azithromycin.

Blood eosinophil counts were > 300 cells/mcL and chronic bronchitis was present clinically. The primary and multiple secondary outcomes were improved with dupilumab.
This is welcome news. I’ve treated countless patients with severe COPD who have repeated exacerbations despite my efforts to prevent them. These patients are on ICS/LABA/LAMA and azithromycin or roflumilast, and occasionally both. While every COPD guideline known to man forbids using chronic oral corticosteroids (OCS), I’ve prescribed them repeatedly because the benefits to keeping a recalcitrant, exacerbating patient out of the hospital seem to outweigh OCS risks. It would be nice to have a better option. Although we were taught that they were immutably distinct in medical school, every first-year pulmonary fellow knows that asthma and COPD share more similarities than differences, so it makes sense that proven asthma therapies would work for some patients with COPD.
However, the dupilumab study must be placed in context. Past studies haven’t been as positive. In 2017, two separate RCTs found that mepolizumab reduced the annual rate of moderate to severe exacerbations (primary outcome) in one trial but not the other. Interpretation gets more complicated when broken down by intention to treat (ITT) vs. modified ITT and when secondary outcomes are considered. Sparing you those details, this trial does not instill confidence, leading the Food and Drug Administration to refuse approval for mepolizumab for COPD. A second RCT of benralizumab for COPD was published in 2019. Much less cognitive load was required to interpret this one; it was negative. FDA approval was not requested.
Looking through the trial designs for the three RCTs of biologics for COPD, I couldn’t find major differences that could explain the discordant results. Sample size and enrollment criteria were similar. As stated, I don’t believe that the biologic data in asthma allow for predicting efficacy in one eosinophilic patient vs. another and I assume the same would be true for COPD. All three trials found that eosinophils were eliminated, so responses were biologically equivalent.
Key takeaways
If trial design and pharmacology don’t account for the disparate outcomes, how do we explain them? More important, how do we translate these trials into clinical practice? I looked for a review or editorial by a scientist-clinician smarter than I so I could steal their ideas and express them as pedantic euphemisms here. I found it curious that I was unable to find one. A recent publication in the American Journal of Respiratory and Critical Care Medicine suggests that the answer lies within the complex lattice of eosinophil subtypes, but I’m unqualified to judge the veracity of this “phenotype within a phenotype” theory.
More trials in COPD are being done. We should have results on tezepelumab, that great savior that may cover noneosinophilic asthma phenotypes, within the next few years. Until then, we’re stuck defying guidelines with the anachronistic use of OCS for the COPD patient who exacerbates through ICS/LABA/LAMA, roflumilast, and azithromycin.

Geriatric care principles should apply to ICUs as well
Baseball legend Leroy “Satchel” Paige famously said that “age is a question of mind over matter: If you don’t mind, it doesn’t matter.”
But even the strongest and most supple minds can’t avoid the effects of advanced age and accompanying physical frailty, and for community-dwelling elderly with pulmonary diseases frailty is a predictor of both hospitalization and death, investigators have found.
For example, among 1,188 community-dwelling older adults enrolled in the Toledo (Spain) Study for Healthy Aging, declining pulmonary function measured by forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) was associated with increased risk for frailty and hospitalization, and a more than twofold greater risk for death in participants both with and without respiratory diseases. These findings were reported by Walter Sepulveda-Loyola, PT, MSC, PhD, from the Faculty of Health and Social Sciences at Universidad de Las Americas in Santiago, Chile, and colleagues in the journal Heart & Lung.
Similarly, results of a meta-analysis performed by investigators at Jiangsu (China) University showed that among 13,203 patients with chronic obstructive pulmonary disease (COPD), frailty was associated with a more than 2.6-fold relative increase in risk for death from any cause, and “prefrailty,” an intermediate state between frailty and “robustness,” was associated with a 48% relative increase in all-cause mortality. Frailty was also associated with a 2.2-fold risk for COPD exacerbations of any severity, the authors reported in JAMDA: The Journal of Post-Acute and Long-Term Care Medicine.
The good (old) USA
In June 2023 the U.S. Census Bureau announced that the median age of the U.S. population is now 38.9 years, and according to a 2016 Census Bureau report funded by the National Institutes of Health, “America’s 65-and-over population is projected to nearly double over the next three decades, from 48 million to 88 million by 2050.”
With the graying of the U.S. population the burden on pulmonary and critical care experts will almost inevitably increase, as evidenced by research from Julien Cobert, MD, from the University of California, San Francisco, and colleagues.
The investigators looked at trends over time in older adults admitted to ICUs from 1988 through 2015 using data from the Health and Retirement Study (HRS), a nationally representative, longitudinal study of older adults. They found that rates of preexisting frailty, disability, and multimorbidity increased over the study period.
“Our findings suggest a growing prevalence of geriatric conditions among older adults admitted to the ICU, suggesting a pressing need to integrate geriatric principles into critical care medicine. Further research could examine if early interventions emphasizing physical, cognitive, mental health, delirium prevention, advance care planning, and rehabilitation individualized to critically ill elderly patients with preexisting geriatric conditions could improve ICU outcomes and post-ICU recovery,” they wrote in a study published in the journal CHEST.
In an editorial accompanying the study by Dr. Cobert and colleagues, Nathan E. Brummel, MD, from The Ohio State University College of Medicine and Davis Heart and Lung Research Institute in Columbus, said “the finding that nearly 30% of overall HRS participants were admitted to the ICU provides novel data about the extent to which older Americans are affected by critical illness. Because the number of older Americans is projected to continue to increase for the next 30 years or more, these data make clear the ongoing importance of aging-focused research and clinical care.”
Dr. Brummel also noted that older adults who are admitted to the ICU today are at greater risk for poor outcomes than those admitted in prior years, as evidenced by the increased prevalence of disability, frailty, and multimorbidity.
“Moreover, because the average age of those admitted to the ICU only changed by 1 year during the study, these data show that increases in vulnerability are not simply due to chronological age, and they suggest that to identify those with greater baseline vulnerability, screening for geriatric syndromes at ICU admission may be warranted,” he wrote.
Geriatric principles in the ICU
“I think what’s most important is that we think about patients from a geriatric principles standpoint, not just when they’re admitted to the hospital but especially when they’re admitted to the ICU,” Dr. Cobert said in an interview.
“The first step is ensuring that we’re asking questions about their underlying comorbidities, especially around frailty, hearing, vision loss, falls, multimorbidities, polypharmacy – things that are primarily done on the outpatient side in geriatric clinics, but things that we should probably be a little bit more cognizant of, given that we’re starting to see higher rates of patients coming in with these issues,” he said.
Critical care specialists need to take a more holistic approach and try to understand as best they can each patients’ goals and then determine whether the ICU staff are acting in concordance with those goals, he emphasized.
For example, ICU clinicians should try to understand whether patients were losing function or having mobility difficulties before hospital and ICU admission, and what they hope to retain when or if they are discharged. ICU staff can then try as much as reasonably possible to minimize interventions that could contribute to impairment after discharge.
Frailty and COPD in the ICU
There are special considerations for frail elderly with obstructive airway disease, Dr. Cobert noted.
Patients with advanced COPD, for example, are likely to be on home oxygen.
“Home oxygen is a big deal,” he said. “It can definitely help with functioning and there’s potentially a mortality benefit in certain populations. But that said, it’s a flammable object that they have to carry around and lug with them all the time. It contributes to falls, it’s tethering, it’s life-limiting in many ways.”
In addition, many patients with COPD have multiple re-hospitalizations, and for clinicians the challenge is “understanding what their goals are, what their motivations are, especially when they live with dyspnea, with advanced lung disease. Is intubation within their goals of care? Has their functional status been declining over time? Are there things that we can optimize holistically and globally as their COPD advances over time?”
Another important component of critical care for the frail elderly is consideration of patients’ palliative care needs and what their symptoms and symptom burdens were like prior to hospitalizations.
“The ICU experience and the critical illness experience may serve as an inflexion point – more likely a downward inflection point – whereby their needs increase, their symptoms can worsen, and their health, especially their global health, worsens. Their preexisting geriatric conditions might be a moving target after another hit and another traumatic stressor like the ICU setting,” Dr. Cobert said.
The study by Dr. Cobert and colleagues was supported by the National Institute on Aging. Dr. Cobert had no reported conflicts of interest.

Pulmonary embolism confers higher mortality long term
Topline
Long-term mortality rates among individuals who have had a pulmonary embolism are significantly higher than rates in the general population.
Methodology
Researchers investigated long-term outcomes of patients with pulmonary embolism in a single-center registry.
They followed 896 patients for up to 14 years.
Data were from consecutive cases treated between May 2005 and December 2017.
Takeaway
The total follow-up time was 3,908 patient-years (median, 3.1 years).
One-year and five-year mortality rates were 19.7% (95% confidence interval, 17.2%-22.4%) and 37.1% (95% CI, 33.6%-40.5%), respectively, for patients with pulmonary embolism.
The most frequent causes of death were cancer (28.5%), pulmonary embolism (19.4%), infections (13.9%), and cardiovascular events (11.6%).
Late mortality (>30 days) was more frequent than in the general population for patients with cancer (5-year standardized mortality ratio, 2.77; 95% CI, 2.41-3.16) and for patients without cancer (1.80; 95% CI, 1.50-2.14), compared with expected rates.

Comorbid respiratory disease key predictor of NTM-PD
(NTM-PD), data from a systematic review of 99 studies indicate.
NTM-PD is frequently underdiagnosed, and data on specific risk factors are lacking, especially for high-risk individuals with preexisting respiratory diseases, wrote Michael R. Loebinger, PhD, of Imperial College London, and colleagues.
“NTM-PD can be a substantial burden for patients, contributing to lung function decline and reduced health-related quality of life, and is associated with significant morbidity and mortality,” they said.
In a study published in the journal Chest, the researchers identified 99 studies published between 2011 and 2021. Of these, 24 reported an association between risk factors and NTM-PD among patients with respiratory disease compared with patients without NTM-PD and with healthy control persons without NTM-PD; these studies were included in the meta-analysis.
Overall, comorbid respiratory disease was significantly associated with an increased risk of NTM-PD, with odds ratios ranging from 4.15 for asthma to 21.43 for bronchiectasis. Other conditions significantly associated with NTM-PD risk included history of tuberculosis (odds ratio, 12.69), interstitial lung disease (OR, 6.39), and chronic obstructive pulmonary disease (COPD) (OR, 6.63).
Other factors associated with increased NTM-PD risk included inhaled corticosteroids (OR, 4.46), oral corticosteroids (OR, 3.37), and other immunosuppressants (OR, 2.60). Additional risk factors were use of anti–tumor necrosis factor-alpha for rheumatoid arthritis (OR, 2.13), solid tumors (OR, 4.66), current pneumonia (OR, 5.54), cardiovascular disease (OR, 1.73), and low body mass index (OR, 3.04).
Additional marginal or nonsignificant associations with NTM-PD risk were found for lung function, diabetes, renal disease, cancer, healthy weight, and infection with either Pseudomonas aeruginosa or Staphylococcus aureus.
Possible protective factors, though not significant, included increasing or high BMI and long-term macrolide use.
Bronchiectasis, which is associated with the highest risk of NTM-PD, was assessed in four studies. It was evaluated less frequently because it was often considered a reason for study exclusion, the researchers wrote in their discussion.
“However, many studies report high numbers of patients with nodular bronchiectatic NTM-PD and is suggested to be almost universal in patients with noncavitary NTM-PD,” they said.
The most common risk factors for NTM-PD in the included studies were the use of immunosuppressants, female sex, COPD comorbidity, and history of suspected tuberculosis.
The findings were limited by several factors, including the high level of heterogeneity among the included studies, the lack of data on attributable risk, and inconsistent definitions of NTM-PD, the researchers noted. However, the results may be useful for highlighting risk factors that could be used to identify high-risk patients and to promote early diagnosis and treatment, they said. In addition, long-term studies are needed regarding the impact of multiple potential risk factors on individual risk for NTM-PD among patients with respiratory disease, they concluded.
The study was supported by Insmed BV. Dr. Loebinger has relationships with Insmed, AstraZeneca, Chiesi, Savara, Parion, Zambon, 30T, Electromed, Recode, AN2 Therapeutics, and Armata.

The findings were limited by several factors, including the high level of heterogeneity among the included studies, the lack of data on attributable risk, and inconsistent definitions of NTM-PD, the researchers noted. However, the results may be useful for highlighting risk factors that could be used to identify high-risk patients and to promote early diagnosis and treatment, they said. In addition, long-term studies are needed regarding the impact of multiple potential risk factors on individual risk for NTM-PD among patients with respiratory disease, they concluded.

(NTM-PD), data from a systematic review of 99 studies indicate.
NTM-PD is frequently underdiagnosed, and data on specific risk factors are lacking, especially for high-risk individuals with preexisting respiratory diseases, wrote Michael R. Loebinger, PhD, of Imperial College London, and colleagues.
“NTM-PD can be a substantial burden for patients, contributing to lung function decline and reduced health-related quality of life, and is associated with significant morbidity and mortality,” they said.
In a study published in the journal Chest, the researchers identified 99 studies published between 2011 and 2021. Of these, 24 reported an association between risk factors and NTM-PD among patients with respiratory disease compared with patients without NTM-PD and with healthy control persons without NTM-PD; these studies were included in the meta-analysis.
Overall, comorbid respiratory disease was significantly associated with an increased risk of NTM-PD, with odds ratios ranging from 4.15 for asthma to 21.43 for bronchiectasis. Other conditions significantly associated with NTM-PD risk included history of tuberculosis (odds ratio, 12.69), interstitial lung disease (OR, 6.39), and chronic obstructive pulmonary disease (COPD) (OR, 6.63).
Other factors associated with increased NTM-PD risk included inhaled corticosteroids (OR, 4.46), oral corticosteroids (OR, 3.37), and other immunosuppressants (OR, 2.60). Additional risk factors were use of anti–tumor necrosis factor-alpha for rheumatoid arthritis (OR, 2.13), solid tumors (OR, 4.66), current pneumonia (OR, 5.54), cardiovascular disease (OR, 1.73), and low body mass index (OR, 3.04).
Additional marginal or nonsignificant associations with NTM-PD risk were found for lung function, diabetes, renal disease, cancer, healthy weight, and infection with either Pseudomonas aeruginosa or Staphylococcus aureus.
Possible protective factors, though not significant, included increasing or high BMI and long-term macrolide use.
Bronchiectasis, which is associated with the highest risk of NTM-PD, was assessed in four studies. It was evaluated less frequently because it was often considered a reason for study exclusion, the researchers wrote in their discussion.

CDC signs off on RSV vaccine for older adults
The Centers for Disease Control and Prevention has given a green light to two new vaccines to protect against respiratory syncytial virus, or RSV, in older adults.
CDC Director Rochelle P. Walensky, MD, MPH, agreed with and endorsed the recommendations made earlier by CDC advisors that people age 60 and over may get one of two new vaccines for RSV. Decisions should be made based on discussions with one’s health care provider about whether the vaccine is right for them, the federal health agency said.
The new vaccines, the first licensed in the United States to protect against the respiratory illness, are expected to be available this fall.
On June 21, the CDC’s Advisory Committee on Immunization Practices (ACIP), an independent panel, stopped short of recommending the vaccines for everyone age 65 and above, which was the original question the committee was to consider. The experts amended that question, changing it to whether the panel should recommend the vaccine for those 65 and above if the person and their doctor agreed. The committee voted 9 to 5 in favor.
RSV vaccines
RSV leads to 6,000 to 10,000 deaths a year in the United States among those age 65 and older and 60,000 to 160,000 hospitalizations in that group. Seniors and infants are among the most vulnerable to the lower respiratory infection, marked by runny nose, wheezing, sneezing, decreased appetite, and fever.
The FDA in May approved two vaccines — GSK’s Arexvy and Pfizer’s Abrysvo — for adults age 60 and above.
The vote recommending shared decision-making about the vaccine, instead of a routine vaccination recommended for all, “is a weaker recommendation,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center in Nashville and medical director of the National Foundation for Infectious Diseases. Dr. Schaffner is a non-voting member of ACIP. He attended the meeting.
He said the experts voiced concern about a number of issues, including what some saw as a lack of sufficient data from trials on the most vulnerable groups, such as nursing home residents.
Experts also wanted more information about the duration of protection and exactly when a second dose might be needed. At the meeting, a GSK official said its vaccine was 84.6% effective after one and a half seasons, down from 94.1% after one season. A Pfizer official said its vaccine decreased the risk of RSV with three or more symptoms by 78.6% after a season and a half, down from 88.9% after one season.
The panel also wanted more data on whether the RSV vaccines could be administered at the same time as other vaccines recommended for adults.
Both companies gave a range of cost estimates. Pfizer expects its vaccine to cost $180 to $270 but said it could not guarantee that range. GSK said it expects a price of $200 to $295. Under the Inflation Reduction Act, recommended vaccines are covered under Medicare for those with Part D plans, which 51 million of 65 million Medicare patients have. Commercial insurance is likely to cover the vaccines if the CDC recommends them.
