Hereditary angioedema in older adults: Understanding the patient perspective.

BACKGROUND: Hereditary angioedema (HAE) is a rare condition characterized by potentially fatal, recurrent episodes of painful swelling. Whereas there are limited studies evaluating the quality of life of individuals with HAE, none have evaluated the impact of HAE on older adults. OBJECTIVE: To evaluate the effect of HAE on older adults through qualitative methodology. METHODS: A group of 3 physicians with extensive research and clinical experience in HAE developed a focus group guidebook highlighting issues of importance to older adults. A total of 17 patients with HAE (type I or II) aged 60 years and older participated in focus groups. Three independent reviewers coded each focus group transcript using a thematic saturation approach. RESULTS: Reviewers identified 7 core themes from the focus groups. The themes identified encompassed the following: (1) challenges with securing medications and insurance concerns; (2) the experience of living with HAE before the advent of newer and more effective therapeutic options; (3) a worsening of HAE attack frequency and severity with aging; (4) the effects of comorbid conditions such as arthritis, memory loss, and irritable bowel syndrome; (5) changes in HAE with menopause; and (6) changing perspective on HAE with age, the effect of HAE on interpersonal relationships including the decision to have children, and goals for future care and research including support groups and a desire to be included in clinical trials. CONCLUSION: Older adults with HAE have specific challenges and concerns that may be unique compared with younger populations. Health care providers should address these to provide optimal care.

Black Emerging Adults With Uncontrolled Asthma: A Qualitative Study.

RATIONALE: Asthma morbidity and mortality are disproportionately high in the Black population, especially among Black emerging adults (BEAs) (age 18-30 years). Few studies have been done to identify unique challenges to asthma care in BEAs. OBJECTIVE: To assess the challenges and barriers to asthma care BEAs experience. METHODS: We conducted virtual focus groups consisting of BEAs (n = 16) with a physician diagnosis of asthma. Discussion questions regarding asthma triggers, management, and challenges were used. Focus group discussions were recorded and transcribed verbatim. The transcripts were then coded by 3 coders using a thematic saturation approach. RESULTS: Seven major domains were identified: heightened anxiety around asthma management; asthma symptoms interfering with school and/or work; asthma in social group setting; transitioning to adulthood leading to increased autonomy and financial independence; use of technology in asthma management; concerns regarding coronavirus disease 2019; and perceived discrimination and biases. These domains create complex barriers to optimal asthma management and overlapping elements were identified. Technology was described as a potential method to address these challenges. CONCLUSIONS: BEAs with asthma have unique challenges due to age and race. Physicians should address these challenges through innovative means such as technology-based interventions.

Assessment of mask use on oxygen saturation in adults and children with asthma.

Background: Mask use is recommended to reduce the transmission of severe acute respiratory syndrome coronavirus 2. The safety of mask use in adults and children with asthma is unknown. Objective: The objective of this study is to evaluate the effect of mask use on peripheral oxygen saturation (SpO2) in those with and those without asthma. Methods: A two-stage cross-sectional study was performed. In the first stage, the SpO2 concentration in adults and children with and without asthma was measured with the adults and children at rest during mask use. In the second stage, children years 6-17 performed a 6-minute walk test while wearing masks. The SpO2 concentration was measured before the exercise and at 3 and 6 minutes into exercise. Subjective dyspnea was evaluated by using the Pediatric Dyspnea Scale (PDS). Results: In the first stage, SpO2 levels in 393 subjects were analyzed. In the second stage, 50 pediatric subjects were included, 25 with and 25 without asthma. There was no difference in SpO2 levels between those with and those without asthma in adults and children wearing masks while at rest, with median SpO2 98% in both groups. There was no difference in oxygen saturation or reported level of dyspnea between the children with asthma and children without asthma performing the 6-minute walk test while wearing masks. Median SpO2 levels were at or near 99% in the asthma and non-asthma groups at all time points. Median PDS scores were similar between the asthma and non-asthma groups. Conclusion: Mask use did not affect SpO2 in adults and children at rest or in children performing low-to-moderate intensity exercise. These findings were consistent in those with and without asthma.

Consequences of Insurance Coverage Delays and Denials for Patients With Hereditary Angioedema.

BACKGROUND: Hereditary angioedema (HAE) is a rare and potentially fatal genetic disease associated with recurrent and unpredictable episodes of angioedema. Although modern therapies have dramatically increased quality of life, insurance changes, delays, and denials are becoming more common. OBJECTIVE: To examine the impact of insurance delays and denials on patient health and well-being. METHODS: A total of 20 patients with HAE (type 1 and 2) who recently experienced insurance delays or denials completed an online survey, and 19 participated in a follow-up focus group. The survey and focus group addressed the impact of insurance challenges on the use of health care services, work/school attendance, and anxiety. Three independent reviewers coded each focus group transcript using a thematic saturation approach. RESULTS: A total of 70% of participants reported an increased frequency of angioedema attacks resulting from insurance delays or denials. More than 50% missed work/school days because of increased attacks, and 90% reported greater anxiety. Twenty-five percent of respondents reported more urgent care or emergency department visits. In focus groups, participants identified specific ways that losing access to medication had a negative impact on their health, family, and work/school life. Insufficient notification of health insurance policy changes and the time and effort required to regain access to medications compounded patients' frustration and anxiety. CONCLUSION: Insurance delays and denials have significant impacts on individuals with HAE including (1) increased urgent care and emergency department visits, (2) missed work/school days, (3) higher levels of anxiety, and (4) a negative impact on family life.

An Electronic Shared Decision-Making App to Improve Asthma Outcomes: A Randomized Controlled Trial.

BACKGROUND: Shared decision-making (SDM) incorporates patient values and preferences to optimize asthma management decisions. Available asthma SDM aids primarily focus on medication selection. OBJECTIVE: To assess the usability, acceptability, and preliminary effectiveness of an electronic SDM application, the ACTION (Active Conversation in asthma Treatment shared decisION-making) app, that addressed medication, nonmedication, and COVID-19 concerns for asthma. METHODS: In this pilot study, 81 participants with asthma were randomized into the control arm or ACTION app intervention. The ACTION app was completed 1 week before a clinic visit, and responses were shared with the medical provider. The primary outcomes were patient satisfaction and SDM quality. Next, ACTION app users (n = 9) and providers (n = 5) provided feedback through separate virtual focus groups. Sessions were coded by comparative analysis. RESULTS: The ACTION app group scored higher agreement that providers adequately addressed COVID-19 concerns compared with the control group (4.4 vs 3.7, P = .03). Although the ACTION app group had a higher total 9-item Shared Decision-Making Questionnaire score, this did not reach statistical significance (87.1 vs 83.3, P = .2). However, the ACTION app group demonstrated stronger agreement that their physician knew exactly how they wanted to be involved in decision-making (4.3 vs 3.8, P = .05), providers asked about preferences (4.3 vs 3.8, P = .05), and that different options were thoroughly weighed (4.3 vs 3.8, P = .03). Major focus group themes included that the ACTION app was practical and established a patient-centered agenda. CONCLUSION: An electronic asthma SDM app that incorporates patient preferences regarding nonmedication-related, medication-related, and COVID-19-related concerns is well accepted and can improve patient satisfaction and SDM.

Reducing Health Disparities in Asthma: How Can Progress Be Made.

Health disparities (recently defined as a health difference closely linked with social, economic, and/or environmental disadvantage) in asthma continue despite the presence of safe and effective treatment. For example, in the United States, Black individuals have a hospitalization rate that is 6× higher than that for White individuals, and an asthma mortality rate nearly 3× higher. This article will discuss the current state of health disparities in asthma in the United States. Factors involved in the creation of these disparities (including unconscious bias and structural racism) will be examined. The types of asthma interventions (including case workers, technological advances, mobile asthma clinics, and environmental remediation) that have and have not been successful to decrease disparities will be reviewed. Finally, current resources and future actions are summarized in a table and in text, providing information that the allergist can use to make an impact on asthma health disparities in 2023.

Vaccination counseling with and without excipient skin testing in patients with suspected allergic reactions to mRNA COVID-19 vaccines and patients with atopy.

Background: Allergic reactions have been reported with mRNA vaccines for COVID-19 prevention. Patients perceived to be at higher risk for a reaction may be referred to an allergist, although evaluation strategies may differ between allergists. Objective: Our aim was to determine outcomes of COVID-19 vaccinations in patients evaluated by an allergist using different approaches. Methods: We conducted a retrospective case series evaluation of 98 patients seen at the University of Michigan Allergy Clinic for concerns regarding COVID-19 vaccination. Of these 98 patients, 34 underwent skin testing with polyethylene glycol (PEG) 2000 with or without PEG 3350/polysorbate 80 testing. Results: Of the 34 patients on whom skin testing was performed, 16 underwent testing before vaccination and 18 underwent testing after a reported vaccine-related event. One patient had a positive skin testing result in response to PEG 3350 following a vaccination reaction and natural infection and was advised against a second dose. One patient with a significant history concerning of anaphylaxis in response to PEG had positive results of testing to identify allergy to PEG 2000, PEG 3350, and polysorbate 80 and was advised against vaccination. Of the 98 patients, 63 (64%) tolerated COVID-19 vaccination without complication after evaluation by an allergist. Conclusion: No significant differences were found between vaccination counseling with and without skin testing to excipients. Patients who presented before the first dose of vaccination were more likely to proceed with COVID-19 vaccination and tolerate vaccination without complication.

Understanding the Updates in the Asthma Guidelines.

Asthma is a chronic inflammatory lung disease that affects millions of Americans, with variable symptoms of bronchospasm and obstruction among individuals over time. The National Heart, Lung, and Blood Institute (NHLBI) published the 2020 Focused Updates to the Asthma Management Guidelines based on the latest research since the 2007 Expert Panel Report-3 (EPR-3). The following article reviews the 21 new recommendations on the six core topics in asthma: use of intermittent inhaled corticosteroids, long-acting muscarinic antagonist therapy, use of the fractional exhaled nitric oxide test in asthma diagnosis and monitoring, indoor allergen mitigation, immunotherapy, and bronchial thermoplasty. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to rate recommendations as strong or conditional based on the evidence. The recommendations were based on systematic reviews of the literature and focused on patient-centered critical outcomes of asthma exacerbations, asthma control, and asthma-related quality of life. Understanding the recommendations with consideration of individual values through shared decision-making may improve asthma outcomes.

Pulmonary Procedures During the COVID-19 Pandemic: A Work Group Report of the AAAAI Asthma Diagnosis and Treatment (ADT) Interest Section.

The COVID-19 pandemic has placed increased demands on the ability to safely perform pulmonary procedures in keeping with Centers for Disease Control and Prevention (CDC), American Thoracic Society (ATS), and the Occupational Safety and Health Administration (OSHA) recommendations. Accordingly, the American Academy of Allergy, Asthma & Immunology (AAAAI) Asthma Diagnosis and Treatment convened this work group to offer guidance. The work group is composed of specialist practitioners from academic and both large and small practices. Individuals with special expertise were assigned sections on spirometry, fractional exhaled nitric oxide, nebulized treatments, and methacholine challenge. The work group met periodically to achieve consensus. This resulting document has recommendations for the allergy/asthma/immunology health care setting based on available evidence including reference documents from the CDC, ATS, and OSHA.

The Magnification of Health Disparities During the COVID-19 Pandemic.

Coronavirus disease 2019 has created and amplified racial health disparities. This has been particularly noticeable in populations with asthma. There is no one simple reason for this occurrence, but rather a complex interaction of biological, structural, and socioeconomic factors. This article will highlight reasons why the coronavirus disease 2019 pandemic has been particularly impactful among minority populations throughout the world and will also offer potential solutions to help overcome health disparities.

Breathing exercises in older adults with asthma: a blinded, randomized, placebo-controlled trial.

OBJECTIVE: Breathing exercises have been found to benefit patients with some respiratory disorders, but can take a significant amount of time to complete. The effects of a breathing exercise program are unknown. The aim of this study was to evaluate the effectiveness of a short multi-component exercise program for older adults with asthma. METHODS: To be included, subjects were age 65 years or older with persistent asthma. 90 subjects with predominantly moderate to severe asthma were randomized, 45 each, into either the exercise or control groups. After in person training at the initial visit, those in the exercise group performed a short three-part exercise program twice per day at home for one month. Those in the control group performed 2 breaths with the incentive spirometer twice per day. At the initial visit patients completed baseline questionnaires assessing demographic information, asthma control (Asthma Control Test - ACT) and quality of life (mini-Asthma Quality of Life Questionnaire - mini-AQLQ) as well as spirometry. After the one-month period at the follow-up visit the ACT, mini-AQLQ, and spirometry were repeated. RESULTS: Subjects in the intervention felt that breathing exercises were helpful, and 87% would recommend them to a friend. Although both groups had improvement in ACT and mini-AQLQ, there were no differences between groups. FEV1 was lower in both groups. CONCLUSION: Although a short breathing exercise program was acceptable for older adults with asthma, it did not produce meaningful improvements in asthma outcomes. A longer program may be necessary.

Asthma care during COVID-19: differences in attitudes and expectations between physicians and patients.

OBJECTIVE: The aim of this study was to explore differences in attitudes, behaviors and expectations related to COVID-19 between physicians and patients with asthma. METHODS: An anonymous survey was distributed through email and social media to adult patients with asthma during a three-week period in April-May 2020. A separate survey was sent to physicians. The surveys asked about demographic information, specific challenges and concerns due to COVID-19, and attitudes/behaviors during this time. RESULTS: A total of 1171 patients and 225 physicians completed the surveys. Overall, patients with asthma and physicians had large differences in expectations related to COVID-19. Patients were more likely than physicians to believe that individuals with asthma are at a higher risk to get COVID-19 (37.5% vs. 12.0%, p < 0.001), have increased anxiety due to COVID-19 (79.6% vs 70.0%, p = 0.002), and should not go to work (62.7% vs 11.9%, p < 0.001). Neither patients nor physicians felt confident they could distinguish COVID-19 symptoms from asthma (61.2% and 74.5% did not feel confident, respectively). Patients with severe asthma were significantly more impacted by the pandemic (e.g., became unemployed [OR 2.15], had difficulty getting asthma medications [OR 2.37]) compared to those with nonsevere asthma. CONCLUSION: Patients with asthma and their physicians have markedly different attitudes and opinions regarding care during the COVID-19 pandemic. Such differences have important implications when providing patient-centered care.Supplemental data for this article can be accessed at publisher's website.

The role of aspirin desensitization followed by oral aspirin therapy in managing patients with aspirin-exacerbated respiratory disease: A Work Group Report from the Rhinitis, Rhinosinusitis and Ocular Allergy Committee of the American Academy of Allergy, Asthma & Immunology.

Aspirin-exacerbated respiratory disease (AERD) is characterized by the clinical triad of chronic rhinosinusitis with nasal polyps, asthma, and an intolerance to medications that inhibit the cycloxgenase-1 enzyme. Patients with AERD on average have more severe respiratory disease compared with patients with chronic rhinosinusitis with nasal polyps and/or asthma alone. Although patients with AERD traditionally develop significant upper and lower respiratory tract symptoms on ingestion of cycloxgenase-1 inhibitors, most of these same patients report clinical benefit when desensitized to aspirin and maintained on daily aspirin therapy. This Work Group Report provides a comprehensive review of aspirin challenges, aspirin desensitizations, and maintenance aspirin therapy in patients with AERD. Identification of appropriate candidates, indications and contraindications, medical and surgical optimization strategies, protocols, medical management during the desensitization, and recommendations for maintenance aspirin therapy following desensitization are reviewed. Also included is a summary of studies evaluating the clinical efficacy of aspirin therapy after desensitization as well as a discussion on the possible cellular and molecular mechanisms explaining how this therapy provides unique benefit to patients with AERD.

2020 Focused Updates to the Asthma Management Guidelines: A Report from the National Asthma Education and Prevention Program Coordinating Committee Expert Panel Working Group.

The 2020 Focused Updates to the Asthma Management Guidelines: A Report from the National Asthma Education and Prevention Program Coordinating Committee Expert Panel Working Group was coordinated and supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. It is designed to improve patient care and support informed decision making about asthma management in the clinical setting. This update addresses six priority topic areas as determined by the state of the science at the time of a needs assessment, and input from multiple stakeholders:A rigorous process was undertaken to develop these evidence-based guidelines. The Agency for Healthcare Research and Quality's (AHRQ) Evidence-Based Practice Centers conducted systematic reviews on these topics, which were used by the Expert Panel Working Group as a basis for developing recommendations and guidance. The Expert Panel used GRADE (Grading of Recommendations, Assessment, Development and Evaluation), an internationally accepted framework, in consultation with an experienced methodology team for determining the certainty of evidence and the direction and strength of recommendations based on the evidence. Practical implementation guidance for each recommendation incorporates findings from NHLBI-led patient, caregiver, and clinician focus groups. To assist clincians in implementing these recommendations into patient care, the new recommendations have been integrated into the existing Expert Panel Report-3 (EPR-3) asthma management step diagram format.

Asthma Disparities During the COVID-19 Pandemic: A Survey of Patients and Physicians.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has demonstrated significantly worse outcomes for minority (black and Hispanic) individuals. Understanding the reasons for COVID-19-related disparities among patients with asthma has important public health implications. OBJECTIVE: To determine factors contributing to health disparities in those with asthma during the COVID-19 pandemic. METHODS: An anonymous survey was sent through social media to adult patients with asthma, and a separate survey was sent to physicians who provide asthma care. The patient survey addressed demographic information including socioeconomic status, asthma control, and attitudes/health behaviors during COVID-19. RESULTS: A total of 1171 patients (10.1% minority individuals) and 225 physicians completed the survey. Minority patients were more likely to have been affected by COVID-19 (eg, became unemployed, lived in a community with high COVID-19 cases). They had worse asthma control (increased emergency visits for asthma, lower Asthma Control Test score), were more likely to live in urban areas, and had a lower household income. Initial differences in attitudes and health behaviors disappeared after controlling for baseline demographic features. Institutional racism was demonstrated by findings that minority individuals were less likely to have a primary care physician, had more trouble affording asthma medications due to COVID-19, and were more likely to have lost health insurance because of COVID-19, and that 25% of physicians found it more challenging to care for black individuals with asthma during COVID-19. CONCLUSIONS: Differences in socioeconomic status and the effects of institutional racism, but not health behaviors, sources of information, or attitudes, are playing a role in disparities seen for patients with asthma during COVID-19.

Are primary care physicians following National Institute of Allergy and Infectious Disease guidelines for the prevention of peanut allergy? A survey-based study.

Background: The 2017 addendum to the National Institute of Allergy and Infectious Diseases (NIAID) guidelines on peanut allergy prevention significantly altered recommendations for patients at risk of developing peanut allergies. It is unknown if primary care physicians are aware of or are following these guidelines. Objective: To assess the knowledge and practice of the NIAID guidelines among primary care physicians. Methods: A survey was developed to assess the knowledge, awareness, and practice behaviors of the NIAID guidelines. It was distributed to pediatric, family medicine, and medicine-pediatric residents and attending physicians at two large academic centers. Responses were analyzed with binary logistic regression. Results: The survey was distributed to 605 providers, with a response rate of 35% (n = 210). The average score was 4.8 of seven questions answered correctly. Of the participants, 53% incorrectly recommended at-home peanut introduction in patients with egg allergy. In addition, 40% of the participants incorrectly believed that the earliest age for peanut introduction was >1 year of age. More than half of the participants were unaware of the new guidelines. On logistic regression, factors associated with adequate knowledge assessment scores were awareness of the guidelines (odds ratio [OR] 2.98 [confidence interval {CI}, 1.34-6.60]), graduation from residency within 5 years (OR 3.60 [95% CI, 1.14-11.35]), and affiliation with the medicine-pediatrics department (OR 4.59 [95% CI, 1.07-19.65]). Conclusion: The primary care providers incorrectly answer one-third of the questions related to the prevention of peanut allergy. Increasing awareness of the 2017 NIAID guidelines may provide an opportunity to improve patient outcomes. There is an urgent need to develop innovative education strategies to publicize these guidelines.

Electronic cigarettes: How confident and effective are allergists, pulmonologists, and primary care physicians in their practice behavior?

Background: There has been a striking increase in electronic cigarette (EC) use in the United States. The beliefs and practices toward ECs among physicians are unknown. Objective: The purpose of this study was to investigate EC practice patterns among allergists, pulmonologists, and primary care physicians. Methods: An anonymous survey was sent to physicians. The survey contained 32 questions and addressed issues related to demographics, cessation counseling behaviors, personal use, and knowledge and beliefs about ECs. Statistical analysis was performed by using analysis of variance, the Pearson χ² test, Fisher exact test, and logistic regression. Results: A total of 291 physicians completed the survey (222 primary care physicians, 33 pulmonologists, and 36 allergists) for a response rate of 46%. The allergists asked about tobacco cigarette use as frequently as did the pulmonologists and more than the primary care physicians (p < 0.001), but they rarely asked about EC use. The pulmonologists scored highest on self-reported knowledge on ECs, although all the groups answered <40% of the questions correctly. The allergists did not feel as comfortable about providing EC cessation counseling as did the pulmonologists and primary care physicians (p < 0.001). All three groups were equally unlikely to recommend ECs as a cessation tool for tobacco cigarette users. Conclusion: Allergists lacked knowledge and confidence in providing education and cessation counseling for EC users. As the number of patients who use these products continues to increase, there is an urgent need for all physicians to be comfortable and knowledgeable with counseling about ECs.
