TOPLINE:

Immunological and quantitative mRNA assays support a pathogenesis role for histamine-releasing factor (HRF), its interaction with HRF-reactive immunoglobulin E and rhinovirus (RV) in asthma severity and exacerbation.

METHODOLOGY:

• Clinical data for healthy controls (HCs) were compared with data from patients with asthma for three distinct cohorts recruited from programs located in Pittsburg, Boston, and Virginia.
• Cohorts differed primarily by total number of participants, median age, description of asthma severity, RV status, and longitudinal follow-up.
• Enzyme-linked immunoassay tests quantified for comparisons total IgE, IgGs, and IgG1 levels occurring in human sera samples and for HRF-reactive IgE, IgG1, and IgG2b in sera from mice inoculated with mouse .
• Anti-IgE stimulation experiments characterized bronchoalveolar lavage (BAL) cell supernatants for tryptase and PGD2 by ELISA and the mRNAs for tryptase and FCER1A
• Effect of inoculated RV infections and/or house dust mite allergen on stimulating HRF secretion from respiratory epithelial cells and in vitro–grown lung BEAS-2B cells was evaluated by Western blots.

TAKEAWAY:

• HRF-reactive IgE and total IgE levels in serum were significantly higher from patients with severe asthma than from HCs and showed a rising trend as severity increased.
• HRF-reactive IgGs and IgG1 levels in serum were lower in people with asthma than in HCs.
• People with asthma with high HRF-reactive IgE, compared with those with low levels, tended to release more tryptase prostaglandin D2 with anti-IgE stimulation of BAL cells.
• RV infection induced HFR secretions from both in vivo– and in vitro–grown respiratory epithelial cells and was associated with higher levels of HRF-IgE at the time of asthma exacerbations, compared with after resolution.

IN PRACTICE:

Inhibiting HRF and HRF-reactive IgE interactions “can be a preventative/therapeutic target” for severe and RV-induced exacerbated asthma conditions.

SOURCE:

The study led by Yu Kawakami, MD, of La Jolla Institute for Allergy & Immunology, California, and colleagues was published in the Journal of Allergy and Clinical Immunology

LIMITATIONS:

Small sample sizes, large median age differences between cohorts, and lack of data for other demographic traits and variant asthma phenotypes or endotypes in some cohorts are noted limitations that may affect result extrapolations and conclusions.

DISCLOSURES:

The authors report there are no conflicts of interest directly related to this study.

Indigenous children or children with new abnormal auscultatory findings were significantly more likely than children in other categories to respond to oral antibiotics for exacerbations related to bronchiectasis, based on data from more than 200 individuals in New Zealand.

Children and adolescents with bronchiectasis are often treated with antibiotics for respiratory exacerbations, but the effects of antibiotics can vary among individuals, and phenotypic features associated with greater symptom resolution have not been identified, wrote Vikas Goyal, PhD, of the Centre for Children’s Health Research, Brisbane, Australia, and colleagues.

Previous studies have suggested that nearly half of exacerbations in children and adolescents resolve spontaneously after 14 days, and more data are needed to identify which patients are mostly likely to benefit from antibiotics, they noted.

In a study published in the journal Chest, the researchers reviewed secondary data from 217 children and adolescents aged 1-18 years with bronchiectasis enrolled in a pair of randomized, controlled trials comparing oral antibiotics with placebo (known as BEST-1 and BEST-2). The median age of the participants was 6.6 years, 52% were boys, and 41% were Indigenous (defined as Australian First Nations, New Zealand Maori, or Pacific Islander). All participants in the analysis received at least 14 days of oral antibiotics for treatment of nonhospitalized respiratory exacerbations.

Overall, 130 children had resolution of symptoms by day 14, and 87 were nonresponders.

In a multivariate analysis, children who were Indigenous or who had new abnormal auscultatory findings were significantly more likely to respond than children in other categories (odds ratios, 3.59 and 3.85, respectively).

Patients with multiple bronchiectatic lobes at the time of diagnosis and those with higher cough scores at the start of treatment were significantly less likely to respond to antibiotics than patients without these features (OR, 0.66 and 0.55, respectively).

The researchers conducted a further analysis to examine the association between Indigenous ethnicity and treatment response. They found no differences in the other response variables of number of affected lobes at diagnosis and cough scores at the start of treatment between Indigenous and non-Indigenous children.

Given the strong response to antibiotics among Indigenous children, the researchers also conducted a mediation analysis. “Respiratory bacterial pathogens were mediated by Indigenous ethnicity and associated with being an antibiotic ‘responder,’ ” they wrote. For new abnormal chest auscultatory findings, both direct and indirect effects on day 14 response to oral antibiotics were mediated by Indigenous ethnicity. However, neither cough scores at the start of treatment nor the number of affected lobes at diagnosis showed a mediation effect from Indigenous ethnicity.

Among the nonresponders, 59 of 87 resolved symptoms with continuing oral antibiotics over the next 2-4 weeks, and 21 improved without antibiotics.

Additionally, the detection of a respiratory virus at the start of an exacerbation was not associated with antibiotic failure at 14 days, the researchers noted.

The findings were limited by several factors including the use of data from randomized trials that were not designed to address the question in the current study, the researchers noted. Other limitations included incomplete clinical data and lack of data on inflammatory indices, potential antibiotic-resistant pathogens in nonresponders, and the follow-up period of only 14 days, they said.

However, the results suggest a role for patient and exacerbation phenotypes in management of bronchiectasis in clinical practice and promoting antimicrobial stewardship, the researchers wrote. “Although there is benefit in treating exacerbations early to avoid treatment failure and subsequent intravenous antibiotics, future research also needs to identify exacerbations that can be managed without antibiotics,” they concluded.

The BEST-1 and BEST-2 studies were supported by the Australian National Health and Medical Research Council and the NHMRC Centre for Research Excellence in Lung Health of Aboriginal and Torres Strait Islander Children. Dr. Goyal had no financial conflicts to disclose.

A potentially protective role for vitamin D in the pathogenesis of chronic obstructive pulmonary disease (COPD) is suggested by the finding that serum 25-hydroxyvitamin D (25[OH]D) concentrations are inversely associated with COPD incidence and mortality. COPD risk was 23% higher in people within the lowest quintile vs. the fourth quintile of 25(OH)D concentrations, according to research appearing in BMJ Open Respiratory Research.

While 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.

A U.S. Food and Drug Administration investigation of injection-site necrosis in some people who received the 23-valent pneumococcal vaccine has concluded that the benefits of the vaccine outweigh the risks.

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.

A U.S. Food and Drug Administration investigation of injection-site necrosis in some people who received the 23-valent pneumococcal vaccine has concluded that the benefits of the vaccine outweigh the risks.

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.

In a test of one of the nation’s most restrictive laws limiting noncompete clauses in medicine, an Indiana pediatric critical-care physician is suing to stop his former hospital employer from controlling his future employment prospects.

David Lankford, DO, acknowledges that he signed a contract with the Lutheran Health Network that included a noncompete clause. However, he claims in a lawsuit filed July 5 in Allen County Superior Court that an Indiana law that took effect 4 days earlier nullifies the clause because he quit his job with cause. 

Indiana’s law is notable among states because if a physician terminates his/her job for cause, the noncompete may be considered unenforceable.

“When you have physicians who are unable to work in their community, it creates a barrier for access to care for patients,” Dr. Lankford said in an interview. “I’m fighting to decrease barriers and continue to have patients be able to see their doctors in their own hometown or their own county.”

Lutheran Health’s media relations department did not respond to requests for comment.
 

Noncompete clauses ‘extremely common’

Non-compete clauses – which typically restrict when and where employees can take future jobs – are common in physician contracts, Anu Murthy, JD, who reviews employee contracts for a firm called Contract Diagnostics, said in an interview.

However, the tide has been turning against them.

About a dozen states and the District of Columbia have enacted legislation to limit the use of noncompetes in employment contracts, and about half of states have pending legislation that could dilute noncompete clauses, Ms. Murthy said. In June, the state of New York sent a noncompete ban bill to the governor’s desk.

For more about state-by-state restrictions on noncompete clauses, check this chart.

In his lawsuit, Dr. Lankford said he was hired in 2017 to work at Lutheran Hospital in Fort Wayne.

Dr. Lankford signed an employee renewal contract in 2020 that included a noncompete clause; his attorneys declined to provide details about the clause because of confidentiality restrictions. 

In 2022, the lawsuit says, Lutheran Hospital told Dr. Lankford that he’d need to take on more work due to layoffs of pediatric hospitalists. His patient load subsequently grew by 4-5 times, and he quit as of Jan. 7, 2023. 

Dr. Lankford wrote that he found a new job at Parkview Regional Medical Center in Fort Wayne, but his former employer threatened to take action under the noncompete clause, and Parkview withdrew its offer.

Among other things, the new Indiana law says that the clauses are not enforceable “if physician terminates the physician’s employment for cause.”

The lawsuit asks for a judge to prevent Lutheran Health Network from enforcing the clause.
 

Impact on patients

The new Indiana law also bans noncompete clauses for primary care physicians. Kathleen A. DeLaney, JD, one of Dr. Lankford’s attorneys, said in an interview that this provision came about because rural legislators didn’t want to add to the challenges of attracting primary care doctors to move to their communities.  

State legislators have become less friendly to noncompete clauses in medicine because they’re wary of the negative effects on patients, Evan Starr, PhD, said in an interview. The clauses prevent doctors from taking new jobs where they could continue to treat their previous patients, said Dr. Starr, associate professor in the department of management and organization at the University of Maryland.

However, he said, hospitals are fighting to preserve the clauses, arguing that they provide a base of patients to physicians in return for their agreement not to go work for a competitor.

The legal landscape may change even more. The Federal Trade Commission has proposed banning the clauses nationally, and a decision is expected in 2024. However, it’s an election year, which may delay a decision, attorney Ms. Murthy said, “and there is also language in the proposed rule that could exempt nonprofit hospitals, which further complicates the issues.”

For now, Ms. Murthy said, “we are still seeing noncompetes and other restrictive covenants in almost every contract we review in all 50 states and across all specialties. We explicitly explain to every client that they should only sign the agreement with the expectation that their specific noncompete will be enforced as written. Large employer groups, including hospital systems, will likely fight any kind of restriction or dilution of noncompetes, and these types of legal challenges could be tied up in court for many years.”

Distinguishing severe asthma from asthma that is difficult to control can present a clinical challenge, especially in primary care settings. Patients with severe asthma often benefit from multidisciplinary assessment and management. 

In this panel ReCAP, experts in allergy, pulmonary disease, and primary care discuss the difference between severe and difficult-to-control asthma and the clinical importance of this distinction. They then outline optimal management of severe asthma using conventional therapies and the six biologics that are now available. 

According to the panelists, patients with asthma that is difficult to control may have comorbidities that have not been addressed and may contribute to their respiratory symptoms. In patients with severe asthma, comorbidities have typically been addressed and patients are adherent to prescribed therapies; their disease worsens if therapy is stepped down. This definition follows the 2022 Global Initiative for Asthma guidelines. 

The experts discuss how tests administered in primary care and specialty settings can distinguish between eosinophilic and non-eosinophilic phenotypes. In patients who continue to have symptoms despite maximized conventional therapies, biologics targeting specific inflammatory pathways may come into play.

The U.S. Food and Drug Administration has approved an injectable monoclonal antibody to protect newborns and infants against respiratory syncytial virus (RSV).

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.”

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.”

Feelings of inadequacy, in terms of skills and expectations in an ever-changing system, are common emotions that many doctors have experienced since the start of the pandemic.

COVID-19 imposed challenges on health care professionals and systems by forcing changes in how doctors organize themselves professionally as well as in their relationships with patients and in their expectations (realistic or not) of their roles. The situation was bound to generate high rates of frustration and discomfort among younger and older physicians. It was compounded by a generational transition of the profession, which was accelerated by the virus. It was not managed by the decision-makers and was painful for doctors and patients.

Impostor syndrome (IS) is a psychological construct characterized by the persistent belief that one’s success is undeserved, rather than stemming from personal effort, skill, and ability. The phenomenon is common among medics for various reasons, including professional burnout. Recent studies have helped to better define the extent and characteristic features of the syndrome, as well as efforts to combat it.
 

Doctors and burnout

Although occupational burnout among physicians is a systemic issue primarily attributable to problems in the practice environment, professional norms and aspects of medical culture often contribute to the distress that individual physicians experience.

These dimensions have been well characterized and include suggestions that physicians should be impervious to normal human limitations (that is, superhuman), that work should always come first, and that seeking help is a sign of weakness. In aggregate, these attitudes lead many physicians to engage in unhealthy levels of self-sacrifice, manifested by excessive work hours, anxiety about missing something that would benefit their patients, and prioritizing work over personal health. These factors are familiar to many hospital-based and family physicians.
 

The impostor phenomenon

The impostor phenomenon (IP) is a psychological experience of intellectual and professional fraud. Individuals who suffer from it believe that others have inflated perceptions of the individual’s abilities and fear being judged. This fear persists despite continual proof of the individual’s successes. These people ignore praise, are highly self-critical, and attribute their successes to external factors, such as luck, hard work, or receiving help from others, rather than to qualities such as skill, intelligence, or ability.

IP is common among men and women. Some studies suggest it may be more prevalent among women. Studies across industries suggest that the phenomenon is associated with personal consequences (for example, low emotional well-being, problems with work-life integration, anxiety, depression, suicide) and professional consequences (for example, impaired job performance, occupational burnout). Studies involving U.S. medical students have revealed that more than one in four medical students experience IP and that those who experience it are at higher risk for burnout.
 

Surveying IS

IS, which is not a formal psychiatric diagnosis, is defined as having feelings of uncertainty, inadequacy, and being undeserving of one’s achievements despite evidence to the contrary. There are five subtypes of IS:

• Perfectionist: insecurity related to self-imposed, unachievable goals
• Expert: feeling inadequate from lacking sufficient knowledge
• Superperson: assuming excessive workloads just to feel okay among peers
• Natural genius: experiencing shame when it takes effort to develop a skill
• Soloist: believing that requesting help is a sign of weakness

Risk factors

Studies suggest that IS is a problem early in the physician training process. There is limited information on IS among physicians in practice.

Because transitions represent a risk factor for IP, the frequent rotation between clerkships and being a “perpetual novice” during medical school training may contribute to the high prevalence. Qualitative studies suggest that, once in practice, other professional experiences (for example, unfavorable patient outcomes, patient complaints, rejection of grants or manuscripts, and poor teaching evaluations or patient satisfaction scores) may contribute to IP.
 

Impact on doctors

Several methods have been used to classify how much the phenomenon interferes with a person’s life. The Clance Impostor Phenomenon Scale is a 20-item scale that asks respondents to indicate how well each item characterizes their experience on a 5-point scale. Options range from “not at all” to “very true.” The sum of responses to the individual items is used to create an aggregate score (IP score). The higher the score, the more frequently and seriously IP interferes with a person’s life.

A simplified version of the IP score was used in a study of 3,237 U.S. doctors that investigated the association between IS and burnout among doctors and to compare their rates of IS with those of other professionals.

Mean IP scores were higher for female physicians than for male physicians (mean, 10.91 vs. 9.12; P < .001). Scores decreased with age and were lower among those who were married or widowed.

With respect to professional characteristics, IP scores were greater among those in academic practice or who worked in the Veterans Affairs medical system and decreased with years in practice.

The highest IP scores were among pediatric subspecialists, general pediatricians, and emergency medicine physicians. Scores were lowest among ophthalmologists, radiologists, and orthopedic surgeons. IP has been independently associated with the risk of burnout and low professional fulfillment.
 

Lessening the impact

An article commenting on the study highlighted the following expert practice strategies that doctors can use to reduce the impact of IS in their professional life.

• Review and celebrate feats that have led to your professional role.
• Share concerns with trusted colleagues who can validate your accomplishments and normalize your feelings by reporting their own struggles with IS.
• Combat perfectionism by accepting that it is okay to be good enough when meeting the challenges of a demanding profession.
• Exercise self-compassion as an alternative to relying on an external locus of self-worth.
• Understand that IS may be common, especially during transitions, such as when entering medical school, graduate medical training, or starting a new career.

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.

Asthma has long been associated with the use of inhalers to control symptoms. The new S2K guideline on the management of asthma, compiled by experts and published in March 2023, aims to change this. “For decades, we have known about medication that can be used to put asthma into remission. The patient can go out or travel on vacation without an inhaler. This is possible. This is a symptom-prevention approach,” said the guideline coordinator Marek Lommatzsch, MD, PhD, head senior physician of the pulmonology department at the University Medicine Rostock, Germany, in an interview.

The guideline was created by the German Respiratory Society, and a further 11 professional societies from Germany and Austria were involved in the update. The authors comprehensively revised the guideline from 2017, and the evidence-based national disease management guideline (NVL) for general asthma care from 2020 was amended.

Erika von Mutius, MD, PhD, pediatrician and professor of pediatric allergology and pulmonology at the Dr. Von Hauner Children’s Hospital, Munich, and director of the Institute of Asthma and Allergy Prevention at Helmholtz Munich, was not directly involved in the guideline. She said, “This guideline is an informed statement that takes the development over recent years into account. It had been anticipated for some time now. For me, the input from pediatricians should be particularly noted.”
 

Anti-inflammatory therapy

The significance of anti-inflammatory therapy was stressed in the NVL from 2020. The new guideline holds that anti-inflammatory therapy should be considered the primary therapeutic option. “We are making a U-turn: only treat the respiratory inflammation. Salbutamol should still only be given in exceptional cases as required,” according to Dr. Lommatzsch.

In the guideline, asthma therapy is described using an updated step-by-step plan. Inhaled glucocorticoids (ICS) represent the most important pillar of therapy. ICS can be used as permanent therapy or as as-needed therapy in fixed combination with formoterol, which rapidly dilates the airways.

Allergen immunotherapy, also known as hyposensitization, and biologics are also effective anti-inflammatory treatments, Dr. Lommatzsch added. “We must ensure that these anti-inflammatory medicines are also used effectively. Mild to moderate forms of asthma can be treated easily by a primary care physician,” he said. Basic diagnostics in the form of a blood sample are required. A somewhat more comprehensive medical history is also needed. “It takes a little more time and involves more than just taking the inhaler out of the cupboard.”

The situation regarding children, however, is a little different with regard to anti-inflammatory therapy, Dr. Von Mutius explained. “Childhood asthma has many forms, and confirming the diagnosis is not always straightforward, especially in infancy. If needed, salbutamol can be prescribed. However, the anti-inflammatory medication should usually also be administered.”

She emphasized that the guideline has been designed in a sophisticated way that offers the option of “using medical experience to see what is suitable for this family or better for this patient. This is still always subject to medical judgment and responsibility. I find this really successful.”
 

Diagnostics using biomarkers

The previous guideline concentrated on measuring lung function as a way of diagnosing asthmatic illness. Three biomarkers were brought to the fore:

• Eosinophils in the blood.
• IgE levels.
• The FeNO test (proportion of nitrogen monoxide in exhaled air).

Slightly amended, the guideline now states that the FeNO test is implemented as “an integral component of specialist diagnosis.”

The test measures the nitrogen monoxide content of exhaled air as an indicator of inflammation in the airways. However, this test must often be paid for by the patient. “In this respect, we want to give a nudge in the direction of the political decision-makers,” emphasized Dr. Lommatzsch.

Dr. Von Mutius added that use of the FeNO test has not been established in many practices and outpatient clinics. The inflammatory marker is also subject to fluctuations. “This is an update to the guideline where we must wait to see the political response.”
 

Which biologic?

Despite treatment with the established therapies, the symptoms of asthma can persist in some people with severe forms of the condition. Biologics are highly effective for these patients and are preferable in the last stage of therapy to long-term therapy with oral steroids, which have numerous side effects. The current guideline provides an overview diagram to help decide which biologic is suitable for which patient.

“There are six biologics that can be used to treat severe asthma. Officially, almost any biologic can be taken into consideration for a patient, since the approvals overlap. Nevertheless, we know that certain patients benefit hugely from certain biologics. A targeted choice should therefore be made,” explained Dr. Lommatzsch.

Biologics were mentioned in the 2020 NVL but not to the great extent that they are in the latest version. “For the first time, we have created an overview diagram for the individual choice of biologic. With it, we have now set a standard,” said Dr. Lommatzsch.

Therapy with biologics has brought about rapid progress for adults. Dr. Von Mutius anticipates challenges in approving such therapeutics for pediatric treatment. “As is often the case, these therapies are not approved for young children. Meanwhile, dupilumab is approved for children aged 6 months and older; unfortunately, the indication for this is actually atopic dermatitis,” she explains.

When using this therapy for pediatric patients, it is therefore important to explain the options to parents and to inform them of side effects. Severe forms of asthma are rare in children; they are uncommon in adults but are more prevalent than in children.
 

Children and adolescents

One new chapter in the guideline describes giving medical advice to adolescents choosing a career. A table has been compiled that contains information regarding jobs and their respective allergy and asthma risk. The table is designed to be displayed in a medical practice.

Another chapter characterizes the interrelation between asthma and mental health. It differentiates between psychiatric comorbidities for which the patient requires professional help and the stress caused by the asthmatic illness itself. Many patients do not have a mental illness but do suffer under the everyday strain of having asthma, said Dr. Lommatzsch. Therefore, it is important to educate patients and their relatives on how to make a strength out of this supposed weakness – the asthmatic illness. “We have established a procedure for this and have summarized its key points in the guideline,” said Dr. Lommatzsch.

Other updates to the guideline cover asthma in different contexts, such as in pregnant women. The updates address adrenal insufficiency as a side effect of the use of steroids over many years. In addition, the guideline contains a chapter on digital apps that can help with diagnostics and medical history.

Dr. Lommatzsch highlighted a new tool. “By using 15 key points summarized in a table, the guideline displays the essential differences between COPD [chronic obstructive pulmonary disease] and asthma in terms of the symptoms and the findings. It is the most modern table available in Germany that differentiates between the two diseases.”

Asthma has long been associated with the use of inhalers to control symptoms. The new S2K guideline on the management of asthma, compiled by experts and published in March 2023, aims to change this. “For decades, we have known about medication that can be used to put asthma into remission. The patient can go out or travel on vacation without an inhaler. This is possible. This is a symptom-prevention approach,” said the guideline coordinator Marek Lommatzsch, MD, PhD, head senior physician of the pulmonology department at the University Medicine Rostock, Germany, in an interview.

The guideline was created by the German Respiratory Society, and a further 11 professional societies from Germany and Austria were involved in the update. The authors comprehensively revised the guideline from 2017, and the evidence-based national disease management guideline (NVL) for general asthma care from 2020 was amended.

Erika von Mutius, MD, PhD, pediatrician and professor of pediatric allergology and pulmonology at the Dr. Von Hauner Children’s Hospital, Munich, and director of the Institute of Asthma and Allergy Prevention at Helmholtz Munich, was not directly involved in the guideline. She said, “This guideline is an informed statement that takes the development over recent years into account. It had been anticipated for some time now. For me, the input from pediatricians should be particularly noted.”
 

Anti-inflammatory therapy

The significance of anti-inflammatory therapy was stressed in the NVL from 2020. The new guideline holds that anti-inflammatory therapy should be considered the primary therapeutic option. “We are making a U-turn: only treat the respiratory inflammation. Salbutamol should still only be given in exceptional cases as required,” according to Dr. Lommatzsch.

In the guideline, asthma therapy is described using an updated step-by-step plan. Inhaled glucocorticoids (ICS) represent the most important pillar of therapy. ICS can be used as permanent therapy or as as-needed therapy in fixed combination with formoterol, which rapidly dilates the airways.

Allergen immunotherapy, also known as hyposensitization, and biologics are also effective anti-inflammatory treatments, Dr. Lommatzsch added. “We must ensure that these anti-inflammatory medicines are also used effectively. Mild to moderate forms of asthma can be treated easily by a primary care physician,” he said. Basic diagnostics in the form of a blood sample are required. A somewhat more comprehensive medical history is also needed. “It takes a little more time and involves more than just taking the inhaler out of the cupboard.”

The situation regarding children, however, is a little different with regard to anti-inflammatory therapy, Dr. Von Mutius explained. “Childhood asthma has many forms, and confirming the diagnosis is not always straightforward, especially in infancy. If needed, salbutamol can be prescribed. However, the anti-inflammatory medication should usually also be administered.”

She emphasized that the guideline has been designed in a sophisticated way that offers the option of “using medical experience to see what is suitable for this family or better for this patient. This is still always subject to medical judgment and responsibility. I find this really successful.”
 

Diagnostics using biomarkers

The previous guideline concentrated on measuring lung function as a way of diagnosing asthmatic illness. Three biomarkers were brought to the fore:

• Eosinophils in the blood.
• IgE levels.
• The FeNO test (proportion of nitrogen monoxide in exhaled air).

Slightly amended, the guideline now states that the FeNO test is implemented as “an integral component of specialist diagnosis.”

The test measures the nitrogen monoxide content of exhaled air as an indicator of inflammation in the airways. However, this test must often be paid for by the patient. “In this respect, we want to give a nudge in the direction of the political decision-makers,” emphasized Dr. Lommatzsch.

Dr. Von Mutius added that use of the FeNO test has not been established in many practices and outpatient clinics. The inflammatory marker is also subject to fluctuations. “This is an update to the guideline where we must wait to see the political response.”
