Allergic rhinitis and asthma symptoms in a real-life study of MP-AzeFlu to treat multimorbid allergic rhinitis and asthma

BackgroundAsthma affects up to nearly 40% of patients with allergic rhinitis (AR). Poor control of AR symptoms is associated with poor asthma control. The goal of this study was to evaluate the effect of AR treatment with MP-AzeFlu on symptoms of AR as well as symptoms of asthma.MethodsThis prospective study used a visual analog scale (VAS) to assess symptoms of AR and asthma before and after treatment with MP-AzeFlu (Dymista®; azelastine hydrochloride plus fluticasone propionate; 1 spray in each nostril twice daily for 2 weeks). Participants suffered from moderate-to-severe AR according to Allergic Rhinitis and its Impact on Asthma criteria, with acute AR symptoms (AR-VAS scores ≥ 50 mm) on inclusion day. In addition to symptom assessment, patients recorded the impact of AR symptoms on quality-of-life measures before, during, and at the conclusion of the treatment period (approximately 14 days). Patients self-reported change in frequency of their usage of asthma reliever medication on the last day of treatment.ResultsOf 1103 study participants, 267 (24.2%) had comorbid asthma. These participants reported using a mean of 5.1 puffs of asthma reliever medication in the week before treatment with MP-AzeFlu. A total of 81.8% of patients with comorbid asthma responded to AR therapy (AR-VAS < 50 mm on at least 1 study day). Among patients with AR and comorbid asthma, MP-AzeFlu was associated with improved VAS scores across all study parameters, including AR symptom severity, asthma symptom severity, sleep quality, daily work or school activities, daily social activities, and daily outdoor activities. Asthma symptom severity decreased from a mean of 48.9 mm to 24.1 mm on the VAS. Self-reported frequency of asthma reliever medication use was reduced for 57.6% of participants (n = 139/241).ConclusionMP-AzeFlu used to relieve AR symptoms was associated with reduced asthma symptom VAS scores and frequency of asthma reliever medication usage. Changes in overall symptoms of AR and asthma were correlated.

Skin prick reactivity among asthmatics in East Africa

BackgroundThe burden of asthma in Africa is high, and yet the disease is not universally prioritised. Data on allergic asthma and its impact on asthma morbidity are limited in Africa. Our aim was to describe the distribution of skin prick positivity among asthmatics in Eastern Africa. MethodsFrom August 2016 to May 2018, 1671 asthmatic patients were enrolled from Uganda, Kenya, and Ethiopia as part of the African Severe Asthma Program clinical study. Skin prick testing was performed at baseline using a panel of 12 allergens, and factors associated with skin prick reactivity determined. ResultsOf the 1, 671 patients recruited, 71% were female with a median age of 40 years, 93.6% were aged >15 years and the patterns of asthma symptom frequency was intermittent in 2.9%, mild persistent in 19.9%, moderate persistent in 42.6% and severe persistent in 34.6% at baseline. Self-reported triggers, were dust (92%), cold weather (89%), upper respiratory infections (84%), strong smells (79%) and exposure to tobacco (78%). The majority (90%) of the participants had at least 1 positive allergen reaction, with 0.9% participants reacting to all the 12 allergens. Participants commonly reacted to house dust mites (66%), Blomia tropicalis (62%), and the German cockroach (52%). Patients sensitized to more allergens (>2) had significantly reduced lung function (FEV ≤ 80%; p = 0.001) and were more likely to visit the emergency department due to asthma (p = 0.012). There was no significant relationship between number of allergens and measures of asthma control, quality of life, and other clinical outcomes. Only the country of origin was independently associated with atopy among African asthmatics. ConclusionThere is a high prevalence of skin prick positivity among East African patients with asthma, with the commonest allergen being house dust mite. Skin reactivity did not correlate well with asthma severity and poor asthma control. The relation between atopy, measured through skin prick testing, and measures of asthma control among asthma patients in Eastern Africa is unclear and needs further study. Trial registrationThe ASAP study was registered prospectively. ClinicalTrials.gov Identifier: NCT03065920; Registration date: February 28, 2017; Last verified: February 28, 2017.

School-Based Telemedicine Interventions for Asthma: A Systematic Review.

BackgroundSchool health systems are increasingly investing in telemedicine platforms to address acute and chronic illnesses. Asthma, the most common chronic illness in childhood, is of particular interest given its high burden on school absenteeism.ObjectiveConduct a systematic review evaluating impact of school-based telemedicine programs on improving asthma-related outcomes.Data SourcesPubMed, Cochrane CENTRAL, CINAHL, ERIC, PsycINFO, Embase, and Google Scholar.Study Eligibility CriteriaOriginal research, including quasi-experimental studies, without restriction on the type of telemedicine.ParticipantsSchool-aged pediatric patients with asthma and their families.InterventionsSchool-based telemedicine.Study Appraisal and Synthesis MethodsTwo authors independently screened each abstract, conducted full-text review, assessed study quality, and extracted information. A third author resolved disagreements.ResultsOf 371 articles identified, 7 were included for the review. Outcomes of interest were asthma symptom-free days, asthma symptom frequency, quality of life, health care utilization, school absences, and spirometry. Four of 7 studies reported significant increases in symptom-free days and/or decrease in symptom frequency. Five of 6 reported increases in at least one quality-of-life metric, 2 of 7 reported a decrease in at least 1 health care utilization metric, 1 of 3 showed reductions in school absences, and 1 of 2 reported improvements in spirometry measures.LimitationsVariability in intervention designs and outcome measures make comparisons and quantitative analyses across studies difficult. Only 2 of 7 studies were randomized controlled trials.Conclusions and Implications of Key FindingsHigh-quality evidence supporting the use of school-based telemedicine programs to improve patient outcomes is limited. While available evidence suggests benefit, only 2 comparative trials were identified, and the contribution of telemedicine to these studies’ results is unclear.

Natural history of asthma symptoms after epidemic thunderstorm asthma: a 3-year longitudinal study.

BackgroundThe world's most catastrophic epidemic thunderstorm asthma event (ETSA) affected Melbourne in 2016. Little is known about the natural history of individuals affected by such extreme events.ObjectiveIn this single center prospective 3-year longitudinal study, symptomatology and behaviors of individuals affected by ETSA were assessed.MethodsStandardized telephone questionnaire was used to evaluate frequency of asthma symptoms, inhaled corticosteroid preventer use, asthma action plan ownership, and healthcare utilization. Questionnaires were administered at 12, 24, and 36 months after 2016 ETSA. Subgroup analyses of the ‘current’, ‘past’, ‘possible,’ and ‘no asthma’ subgroups were also conducted.ResultsTwo hundred and eight, 164, and 112 completed questionnaires were analyzed in 2017, 2018, and 2019, respectively. Seventy to eighty five percent of respondents reported ongoing asthma symptoms in any given year, of which 20%–28% experienced weekly symptoms. Nearly 50% of respondents were prescribed preventers, with approximately 45% adherent at least 5 days a week. Less than 40% had an asthma action plan and 15%–20% sought urgent medical attention for asthma over the follow-up period. Among 106 individuals with 3 consecutive years of completed questionnaires, those with no prior doctor diagnosis of asthma were significantly more likely to be asymptomatic on follow-up than those with a prior doctor diagnosis of asthma (p = 0.02). Subgroup analyses suggest that large proportions of respondents with ‘past’ and ‘no asthma’ continue to remain symptomatic throughout the 36-month period.ConclusionIn individuals affected by ETSA, we found evidence of ongoing loss of asthma control in those with previously well controlled asthma, and the persistence of symptoms suggestive of asthma in those with no history or symptoms suggestive of prior asthma, even after 36 months from initial ETSA. Low rates of inhaler adherence and asthma action plan ownership may contribute to increased morbidity and mortality from future ETSA events. Further research is required to confirm these findings.

Long-term assessment of aspirin desensitization shows successful bridging with non-aspirin nonsteroidal anti-inflammatory drugs for procedures.

Background: Aspirin (ASA) desensitization and continuous daily ASA therapy is the criterion standard treatment for ASA-exacerbated respiratory disease (AERD). However, the optimal maintenance dosage of ASA and safety of "bridging" patients with AERD and with alternative cyclooxygenase-1 inhibitors for surgery have not been determined and require further investigation. Objective: This study was designed to compare the long-term effects of different maintenance doses of ASA and to assess the success of bridging subjects with AERD for surgery without losing desensitization. Methods: We retrospectively assessed 36 subjects with AERD who successfully underwent ASA desensitization from 2011 to 2017. We performed comprehensive medical record reviews and subsequent telephone interviews with a questionnaire. Results: Of 36 subjects, the average age was 52.8 years, with an average of 3.2 years since desensitization, and 65% were women. The subjects reported a decrease in frequency of nasal symptoms (p < 0.001), asthma symptoms (p = 0.016), and sinus infections (p < 0.001) after desensitization. Improvements were reported in sense of smell, taste, quality of sleep, and quality of life (p < 0.001) in all dosage groups. Thirteen subjects required stopping of ASA for surgeries. Six subjects (46%) were bridged with ibuprofen on an average of 5.9 days before surgery and restarted ASA on an average of 1.3 days after surgery, with no incidence of major adverse events or loss of desensitization. Seven subjects (54%) were not bridged, with three subjects restarting ASA after surgery without symptoms and four subjects losing desensitization. Conclusion: There did not seem to be a difference of benefits between 325 mg once or twice a day compared with 650 mg once or twice a day, but our small subject numbers made this conclusion difficult to prove. Desensitization improved subjective reporting on sleep quality as well as quality of life. Bridging the subjects with AERD who required surgery by using ibuprofen seemed to be safe and effective in maintaining ASA desensitization.

Health communications: provider assessment of asthma control

Objective: The patient–provider partnership is important for effective asthma care and improved asthma control. Our descriptive study describes demographic differences associated with patient–provider asthma communications using Healthy People 2020 indicators.Methods: Using 2013 National Health Interview Survey (NHIS) data, we examined provider assessments of asthma control at last healthcare visit for children and adults with current asthma; assessments included questions on frequency of asthma symptoms, use of quick-relief inhalers, and limitation of daily activities due to asthma. We calculated weighted prevalence and prevalence ratios (PR) with 95% confidence intervals (CI).Results: Overall, 3,684 (weighted prevalence = 7.3%; 95% confidence interval [CI] = 7.0–7.6) NHIS respondents reported current asthma. Among persons with current asthma, 58% reported a routine asthma care visit in the past year. Provider assessments of asthma symptoms, quick-relief inhaler use, and activity limitations were reported by 55.4%, 59.1% and 41.5% of respondents, respectively. Non-Hispanic blacks (PR = 1.11; 95% CI = 1.03–1.20), Puerto Ricans (PR = 1.23; 95% CI = 1.08–1.40), and Other-Hispanics (PR = 1.18; 95% CI = 1.05–1.32) were asked more often than non-Hispanic whites about ≥1 of the asthma control indicators. Providers more frequently assessed asthma symptoms (PR = 1.20; CI = 1.10–1.30), quick-relief inhaler use (PR = 1.10; CI = 1.02–1.19), and activity limitations (PR = 1.25; CI = 1.11–1.41) in children than adults.Conclusions: Healthcare providers often discuss asthma control indicators with patients. Children and some racial and ethnic minorities were more frequently assessed on key asthma control indicators compared to adults and non-Hispanic whites, respectively. These findings may reflect provider efforts to target asthma control communications to populations with higher risk of morbidity.

Abstract # 3150 Mindfulness-Based Stress Reduction training improves disease control and reduces reactivity in affective neurocircuitry in asthmatic individuals

Stress and emotion contribute to the frequency and severity of asthma symptoms. Yet, research directed toward understanding and managing the pathophysiology of asthma has neglected the brain almost entirely. Here, we examined changes in responsivity of emotion-related neural circuitry and asthma control produced by Mindfulness-Based Stress Reduction (MBSR), relative to a wait-list control group (WL). We used functional magnetic resonance imaging (fMRI) during an asthma-specific variant of the Stroop Task where participants identified the color of asthma-related, negative, and neutral words. Asthma control assessments combined self-reported symptoms with medication use and objective measures of lung function. In preliminary results, the MBSR group showed improvements in asthma control relative to controls. The MBSR group also showed a time x valence interaction in a region spanning the lateral orbitofrontal and inferior frontal gyri, such that response to asthma compared to neutral words decreased post-MBSR training. This region is thought to be a convergence zone for processing semantic and emotional content and is closely related to the function of its neighbor, the anterior insula. Across all participants, the greater the reduction in responsivity in this region, the greater the improvement in asthma control. These data may reflect a decrease in the salience intensity of asthma-related words as emotional reactivity abates and/or asthma control improves, and suggest a potential mechanism through which MBSR leads to improvements in asthma management.

Continued loss of asthma control following epidemic thunderstorm asthma.

BackgroundEpidemic thunderstorm asthma (ETSA) severely affected Melbourne, Australia in November 2016. There is scant literature on the natural history of individuals affected by ETSA.ObjectiveA multicentre 12-month prospective observational study was conducted assessing symptomatology and behaviors of ETSA-affected individuals.MethodsWe used a structured phone questionnaire to assess asthma symptom frequency, inhaled preventer use, asthma action plan ownership and healthcare utilization over 12 months since the ETSA. Analysis of results included subgroup analyses of the “current,” “past,” “probable,“ and “no asthma” subgroups defined according to their original 2016 survey responses.ResultsFour hundred forty-two questionnaires were analyzed. Eighty percent of individuals reported ongoing asthma symptoms at follow-up, of which 28% were affected by asthma symptoms at least once a week. Risk of persistent asthma symptoms was significantly higher in those with prior asthma diagnosis, current asthma, and probable undiagnosed asthma (all p < 0.01). Of 442 respondents, 53% were prescribed inhaled preventers, of which 51% were adherent at least 5 days a week. Forty-two percent had a written asthma action plan and 16% had sought urgent medical attention for asthma in the preceding year.ConclusionsFollowing an episode of ETSA, patients experience a pivotal change in asthma trajectory with both loss of asthma control and persistence of de novo asthma. Suboptimal rates of inhaled preventer adherence and asthma action plan ownership may contribute to asthma exacerbation risk and susceptibility to future ETSA episodes. Longer-term follow-up is needed to determine the extent and severity of this apparent change.

Association between second hand smoke (SHS) exposure and caregiver stress in children with poorly controlled asthma

Objective: Urban children with asthma experience high rates of second hand smoke (SHS) exposure. The objective was to examine whether SHS exposure is associated with symptom frequency in children with poorly controlled asthma. Methods: Children were enrolled in a RCT to test the efficacy of an environmental control behavioral intervention versus an attention control group and followed over 12 months. SHS exposure assessed using salivary cotinine measurement. Frequency of child asthma symptoms, healthcare utilization, household smoking and caregiver daily life stress were obtained via caregiver report. Time of enrollment was recorded to assess seasonal factors. Symptom days and nights were the primary outcomes. Multivariable models and odds ratios examined factors that best predicted increased frequency of daytime/nighttime symptoms. Results: Children (n = 222) with a mean age of 6.3 (SD 2.7) years, were primarily male (65%), African American (94%), Medicaid insured (94%), and had poorly controlled asthma (54%). The final multivariable model indicated symptoms in the fall (OR 2.78; 95% CI 1.16, 6.52) and increased caregiver daily life stress (OR 1.13, 95% CI 1.02, 1.25) were significantly associated with increased symptom days when controlling for cotinine level, intervention status, child age and home and car smoking restrictions. Conclusions: There was no impact of SHS exposure on increased symptom frequency. High caregiver daily life stress and symptoms in fall season may place children with asthma at risk for increased day/nighttime symptoms. Close monitoring of symptoms and medication use during the fall season and intervening on caregiver life stress may decrease asthma morbidity in children with poorly controlled asthma.Trial registration: ClinicalTrials.gov identifier: NCT01981564.

Comprehensive Community-Based Intervention and Asthma Outcomes in African American Adolescents.

African American adolescents (age 12-16 years) with moderate-to-severe persistent asthma and ≥1 inpatient hospitalization or ≥2 emergency department visits in 12 months were randomly assigned to Multisystemic Therapy-Health Care or an attention control group (N = 167). Multisystemic Therapy-Health Care is a 6-month home- and community-based treatment that has been shown to improve illness management and health outcomes in high-risk adolescents by addressing the unique barriers for each individual family with cognitive behavioral interventions. The attention control condition was weekly family supportive counseling, which was also provided for 6 months in the home. The primary outcome was lung function (forced expiratory volume in 1 second [FEV1]) measured over 12 months of follow-up. Linear mixed-effects models revealed that compared with adolescents in the comparison group, adolescents in the treatment group had significantly greater improvements in FEV1 secondary outcomes of adherence to controller medication, and the frequency of asthma symptoms. Adolescents in the treatment group had greater reductions in hospitalizations, but there were no differences in reductions in emergency department visits. A comprehensive family- and community-based treatment significantly improved FEV1, medication adherence, asthma symptom frequency, and inpatient hospitalizations in African American adolescents with poorly controlled asthma. Further evaluation in effectiveness and implementation trials is warranted.

The Role of Hypogammaglobulinemia in Childhood Asthma

Background: The relationship between hypogammaglobulinemia and wheezing in childhood has been previously revealed. Objectives: The study aimed to investigate co-morbid immune deficiency in unresponsive asthmatic children, characterize the type of immune deficiency, and determine any possible effect of immune deficiency treatment on the applied standard guideline of asthma treatment. Methods: This was a prospective study conducted between January 2012 and December 2014. A total of 286 children whose serum immunoglobulin (Ig) levels had been analyzed were collected. Among those children, 125 (m/f = 79:46, mean +-SD of age = 41.3 + 25.2 months) were enrolled as they had uncontrolled moderate to persistent asthma. Those 125 children were categorized as the only asthma group and the asthma + hypogammaglobulinemia (HGG) group depending on their immunoglobulin concentrations. Results: Seventy-six of the 125 children (60.8%) had co-morbid hypogammaglobulinemia. Atopy was higher in the Asthma + HGG group (P = 0.044). The most frequent co-morbid HGG was transient hypogammaglobulinemia of infancy (THGI) (46.1%) and IgG subclass deficiency (32.9%). Although the comparison of the percentage use of the inhaled corticosteroids (ICSs) showed no significant difference between the two groups at the initial evaluation, the dose of ICS significantly decreased only in the asthma + HGG group (P = 0.017). Conclusions: The majority of asthmatic children having symptoms despite appropriate guideline-based treatment may have a co-morbid immunological abnormality. Presented data demonstrated the necessity of immunological evaluation of uncontrolled asthmatic children to prevent long-term side effects of high-dose ICS, reduce the frequency and severity of asthma symptoms, and improve the quality of life.

The impact of housing type on low-income asthmatic children receiving multifaceted home interventions.

This study sought to evaluate whether government-assisted vs market-rate housing type influences the frequency of asthma symptoms or the quality of life scores among low-income urban children. In addition, the study sought to evaluate whether housing type influenced the success of in-home environmental and educational interventions in improving children's asthma symptoms or quality of life scores. This was a before-and-after intervention design. Comprehensive health and environmental assessments and subsequent interventions were completed in 176 low-income households with 257 asthmatic children living in government-assisted housing and market-rate housing in Lowell, Massachusetts. We collected environmental and health data with questionnaires at a baseline and a 12-month follow-up visit using the Children's Health Survey for Asthma and a walk-through environmental checklist. Education, tools to remove asthma triggers from the home, and home repairs and remediation were included in the interventions. As in other studies of multifaceted home interventions, there were significant improvements in all asthma symptoms, reductions in healthcare utilization related to asthma, and improvements in quality of life domains for children in both housing types. Environmental indices also improved from the baseline to the final assessment for both housing types. However, the housing type was an important factor in predicting a child's asthma status at the start of the study, with children living in government-assisted housing having significantly better physical health scores (76.8 of 100) and family emotional health scores (74.8 of 100) and fewer overnight hospital stays (mean of 0.02 in the previous 4 weeks) than children living in market-rate housing (67.6, 71.6, and 0.06, respectively). Examination of the change in the health status over the 1-year study period found that children living in market-rate housing had significantly larger reductions in the number of asthma attacks (0.43 in the previous 4 weeks versus 0.24 in assisted housing) and overnight hospital stays (0.06 in the previous 4 weeks versus 0.01 in assisted housing) and larger improvements in physical health quality of life scores (54% improved versus 25.5% in assisted housing). Public assistance for low-income urban housing is associated with better health among children with asthma, and may influence the impact the in-home interventions have on health outcomes because children in market-rate housing have more prospects for improvement in their asthma-related health.

Asthma trigger perceptions are associated with work disability.

To study the association between perceptions of various triggers of asthma and employment status. A questionnaire was administered to all those adults living in the city of Tampere, Finland, who were entitled to special reimbursement for asthma medication by the Social Insurance Institution (n = 2613). The response rate was 79%. The study population (n = 1657) consisted of individuals who worked full-time (n = 967), were unemployed (n = 197), had all-cause work disability (n = 334), or were retired due to old age (n = 159). Given a list of potential asthma triggers, the respondents were asked how often (never/sometimes/often) the trigger caused or worsened their asthma symptoms during leisure time. After adjusting for background variables (age, sex, smoking, and professional status), frequency of asthma symptoms, and the use of asthma medication during the last year, any individual trigger identified as asthma-relevant was associated with having work disability (vs. working full-time). The highest odds ratio (OR) was found for vehicle exhaust (OR 5.0, CI 2.2-11.4). We found similar but less consistent associations between asthma trigger perceptions and unemployment. No elevated ORs were found regarding asthma trigger perceptions for old-age retirement. Perceptions of asthma triggers are associated with all-cause work disability. Our findings suggest that asthmatics have excess trigger perceptions that are not explained by asthma alone. Asthmatics need to be informed that inaccurate trigger perceptions may develop, and how they are induced, because unnecessary trigger avoidance may interfere with work life.

Evaluation of Early Detection Program of Bronchial Asthma in Primary Health Centers of Al-Nasiriyah City/ 2016

One of the main important public health objectives is the prevention of childhood asthma. Evaluating the effectiveness of early detection of childhood asthmatic symptoms, followed by a counseling intervention at preventive child health centers is the corn stone of this study. Early detection and counseling is expected to reduce the prevalence of asthma symptoms and improve health quality in general. This study aimed to evaluate the early detection program of asthma through structure or preconditions of early detection program of asthma, process to be carried out to deliver this program, outcome (Intermediate and ultimate indicators) and lastly opinion of consumers and providers. Evaluation type of study had been conducted all over the 2016. Nine health care centers were involved since the 1st week of January 2016, where an early detection tool had been applied at age groups 1, 2-5, 6 and more than 6 years at the intervention centers. Children who met the intervention criteria received counseling intervention (personal advice to parents to prevent the child from exposure to smoking, and/or referral to the general practitioner or asthma nurse). The primary outcome was asthma diagnosis at age 6 years. Secondary outcomes included frequency and severity of asthma symptoms, health-related quality of life at age 6 years. Analysis was done according to the intention-to-treat principle. Data collection was completed at the 1st of November 2016. Evaluation of the present input, process of PHC for early detection program resulted in: Providing most of the human resources in terms of laboratory assistants and coordinators of the program. Providing most of the material resources such as pressure gauges, medical handset and scales and tape measure height and waist needed to work in the laboratory with the availability of a suitable place for the work program staff to do their job and appliances. The percentage for input was 60% for all PHCs. While regarding consumer satisfaction: Most of consumer are highly satisfied 149 (80.1%) while not satisfied only 8 (4.3%) and high numbers gave the reason due to good services 97 (52.5%) and no comments 71 (38.2%). Regarding the proportion of the detected cases for different non communicable diseases was 44.1% of the whole population that have alarming sign and symptoms of NCD. The lack of doctors of all spatiality (GP, graduted doctors and specialist), lack of some essential tools, following wrong guidelines for this program by general health department by abolishment many ministerial guidelines, human mistakes and lack of training of staff of program, there no feedback mechanism for referral patient from hospital to PHC, lack of some treatment and investigations and some services not free.

Disease Burden of Mild Asthma: Findings from a Cross-Sectional Real-World Survey.

IntroductionMost asthma patients have mild disease, although the burden of mild asthma is not well understood nor studied. Some evidence suggests that many patients with mild asthma experience suboptimal symptom control and exacerbations. This study characterizes the burden of illness and treatment patterns among patients with a confirmed diagnosis of mild asthma, defined as GINA Step 1 or Step 2, and residing in China, France, Germany, Italy, Japan, Spain, the United Kingdom, or the United States.MethodsThe Respiratory Disease-Specific Programme prospective cross-sectional survey was conducted with primary care and specialty physicians in each of the eight countries. Physician and patient surveys assessed demographic and clinical characteristics, frequency and timing of asthma symptoms, exacerbations, and rescue inhaler usage, the most recent FEV1% predicted, and healthcare utilization. GINA Step was determined by prescribed treatment regimen. GINA Step 1 patients were prescribed as-needed reliever medication and Step 2 required treatment with a low-dose inhaled corticosteroid, leukotriene receptor antagonist, or theophylline. Treatment adherence was assessed with the Morisky Medication Adherence scale, disease control with the Asthma Control Test, and work and activity impairments with the Work Productivity and Activity Impairment scale.ResultsThe sample included 1115 GINA Step 1 and 2 patients, with 53% classified as Step 2. Overall asthma control was suboptimal, with reports of nocturnal symptoms (40.6%), symptom worsening (10.5%), and rescue inhaler usage in the last 4 weeks (33.6%). 25% of patients were uncontrolled. The overall mean number of exacerbations in the last 12 months was 0.4, with a higher frequency of exacerbations in Step 2 patients who also experienced more exacerbations requiring treatment intensification, an emergency department visit, or hospitalization.ConclusionMild asthma imposes a substantial burden on patients, establishing the need for comprehensive management plans and ongoing support for treatment adherence.FundingAstraZeneca.

Paradoxical vocal fold motion (PVFM) in pediatric otolaryngology

IntroductionParadoxical vocal fold motion (PVFM) is a condition in which the vocal cords exhibit inappropriate inspiratory adduction, and it has been poorly studied in the pediatric population. MethodsPediatric patients diagnosed with PVCM by a pediatric otolaryngologist and doctor of speech pathology from 2008 to 2012 were reviewed. Patients in whom another cause for their respiratory disturbance was eventually identified were excluded. Patient demographics, characteristics, treatment, and outcomes were reviewed. The study was approved by the Institutional Review Board at our institution. ResultsThirty patients met criteria for inclusion; one with chiari malformation was excluded. 17/29 (59%) were female. Body mass index (BMI) numbers ranged from 16 to 25 with a mean of 21. 9/29 (31%) competed at the highest level of a sport; only 3/29 (10%) did not participate in athletics. Average age of onset was 12.0years; average diagnosis delay was 1.3years. Mean follow up was 2.3years. 24/29 (83%) were previously treated for asthma. 23/29(79%) were previously treated for reflux. 25/29(86%) completed at least one session of respiratory and laryngeal control therapy with overall average of 2.2 sessions completed. All patients who attended a second therapy session were recorded as having improvement in symptoms. ConclusionsPediatric patients with PVFM often participate in high levels of organized sports and the frequency of concurrent asthma and reflux symptoms in this population supports the theory that laryngeal hypersensitivity contributes to the pathophysiology of PVFM. These patients were not found to have any associated psychiatric diagnoses. Pediatric patients with PVFM have an excellent prognosis when treated with speech therapy and for comorbid conditions as indicated.

Should recommendations about starting inhaled corticosteroid treatment for mild asthma be based on symptom frequency: a post-hoc efficacy analysis of the START study

Low-dose inhaled corticosteroids (ICS) are highly effective for reducing asthma exacerbations and mortality. Conventionally, ICS treatment is recommended for patients with symptoms on more than 2 days per week, but this criterion has scant evidence. We aimed to assess the validity of the previous symptom-based cutoff for starting ICS by establishing whether there was a differential response to budesonide versus placebo for severe asthma exacerbations, lung function, and asthma symptom control across subgroups identified by baseline asthma symptom frequency. We did a post-hoc analysis of the 3 year inhaled Steroid Treatment As Regular Therapy (START) study, done in 32 countries, with clinic visits every 3 months. Patients (aged 4-66 years) with mild asthma diagnosed within the previous 2 years and no previous regular corticosteroids were randomised to receive once daily, inhaled budesonide 400 μg (those aged <11 years 200 μg) or placebo. Coprimary outcomes for this analysis were time to first severe asthma-related event (SARE; hospital admission, emergency treatment, or death) and change from baseline in lung function after bronchodilator. Interaction with baseline symptom frequency was investigated, with patients grouped by more than two symptom days per week and two or fewer symptom days per week (divided into no days to 1 day, and more than 1 day to 2 days). Analysis was done by intention to treat. Of 7138 patients (n=3577 budesonide; n=3561 placebo), baseline symptom frequency was 0-1 days per week for 2184 (31%) participants, more than 1 and less than or equal to 2 symptom days per week for 1914 (27%) participants, and more than 2 symptom days per week for 3040 (43%) participants. For budesonide versus placebo, time to first SARE was longer across symptom frequency subgroups (hazard ratios 0·54 [95% CI 0·34-0·86] for 0-1 symptom days per week, 0·60 [0·39-0·93] for >1 to ≤2 symptom days per week, 0·57 [0·41-0·79] >2 symptom days per week, pinteraction=0·94), and the decline in postbronchodilator lung function was less at 3 years' follow-up (pinteraction=0·32). For budesonide versus placebo, severe exacerbations requiring oral or systemic corticosteroids were reduced (rate ratio 0·48 [0·38-0·61] 0-1 symptom days per week, 0·56 [0·44-0·71] >1 to ≤2 symptom days per week, and 0·66 [0·55-0·80] >2 symptom days per week, pinteraction=0·11), prebronchodilator lung function was higher, and symptom-free days were more frequent (p<0·0001 for all three subgroups), with no interaction by symptom frequency (prebronchodilator pinteraction=0·43; symptom-free days pinteraction=0·53). Similar results were noted when participants were classified by any guidelines criterion as so-called persistent versus so-called intermittent asthma. In mild recent-onset asthma, once daily, low-dose budesonide decreases SARE risk, reduces lung function decline, and improves symptom control similarly across all symptom subgroups. The results do not support restriction of inhaled corticosteroids to patients with symptoms on more than 2 days per week and suggest that treatment recommendations for mild asthma should consider both risk reduction and symptoms.

The Role of Surgery in Management of Samter's Triad: A Systematic Review.

Aspirin-exacerbated respiratory disease (AERD) represents a severe form of chronic rhinosinusitis (CRS) characterized by nasal polyposis, bronchial asthma, and aspirin intolerance. This syndrome, known as Samter's triad, is more difficult to manage than routine CRS and poses a challenge to the treating clinician. We performed a systematic review of the literature to determine the role of endoscopic sinus surgery in patients with AERD who are on adjuvant medical therapies. PubMed, Embase, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, Cochrane Technology Assessments, Cochrane Economic Evaluations, Cochrane Groups, and Clinicaltrials.gov. A systematic review of the literature was performed using the 2009 PRISMA guidelines. Studies with both preoperative and postoperative data for patients with AERD who underwent sinus surgery were considered appropriate for inclusion. Publications were written in English, included patients aged 18 years or older, and had a minimum follow-up of 3 months. Eighteen studies met criteria for inclusion in our review. The primary outcome was change in symptom profile as measured by sinonasal and asthma symptom scores. Most studies demonstrated improvement in sinus- and asthma-related symptoms and quality-of-life measures after endoscopic sinus surgery. This review, which did not exclude the use of concomitant medical therapy, suggests that surgery is beneficial in AERD management. Evidence demonstrates improvement in sinonasal and asthma symptom severity and frequency, radiographic and endoscopy scores, and quality of life after surgery.

Impact of Goal Setting and Goal Attainment Methods on Asthma Outcomes

Optimal use of goal-setting strategies in self-management efforts with high-risk individuals with asthma is not well understood. This study aimed to describe factors associated with goal attainment in an asthma self-management intervention for African American women with asthma and determine whether goal attainment methods proved beneficial to goal achievement and improved asthma outcomes. Data came from 212 African American women in the intervention arm of a randomized clinical trial evaluating a telephone-based asthma self-management program. Telephone interview data were collected to assess goals and goal attainment methods identified, asthma symptoms, asthma control, and asthma-related quality of life at baseline and 2-year follow-up. Generalized estimating equations were used to assess the long-term impact of goal setting and goal attainment methods on outcomes. The average age of the sample was 42.1 years ( SD = 14.8). Factors associated with goal attainment included higher education ( p < .01) and fewer depressive symptoms ( p < .01). Using a goal attainment method also resulted in more goals being achieved over the course of the intervention (Estimate [ SE] = 1.25 [0.18]; p < .001) when adjusted for clinical and demographic factors. Use of and types of goal attainment methods and goals were not found to significantly affect asthma control, quality of life, or frequency of nighttime asthma symptoms at follow-up. Using a method to achieve goals led to greater goal attainment. Goal attainment alone did not translate into improved asthma outcomes in our study sample. Further studies are warranted to assess the challenges of self-management in chronic disease patients with complex health needs and how goal setting and goal attainment methods can be strategically integrated into self-management efforts to improve health endpoints.

Insights, attitudes, and perceptions about asthma and its treatment: a multinational survey of patients from Europe and Canada

Background Asthma surveys completed within the past 10 years in the Americas and the Asia-Pacific region have shown significant underassessment of asthma severity in addition to undertreatment of asthma and have suggested the need to improve long-term asthma management. In this study, we examined the frequency of asthma symptoms and severe episodes, patients’ perceived asthma control, and use of asthma medications in Europe and Canada.Methods The Asthma Insight and Management survey (54 questions) was conducted in Europe (Germany, Italy, Spain and the United Kingdom) and Canada from June 14 through July 28, 2010. Telephone interviews were conducted with randomly screened patients or parents of adolescents (aged 12–17 years) with asthma; patients younger than 12 years of age were excluded from the survey. Responses were reported separately for each country and in total for all five countries.Results Seventy-five thousand three hundered thirty-five households were screened, and 2003 patients were interviewed. The survey respondents represented a wide range of severity. Overall, 26 % of patients reported symptoms daily or most days over the past 4 weeks, but most patients (81 %) perceived their asthma to be well or completely controlled. Over the past year, 41 % of patients had episodes of frequent/severe symptoms, and 50 % reported acute treatment (e.g. hospitalization, emergency visit, unscheduled physician visit) for asthma. Across countries, 52 % of patients reported taking controller medication every day over the past year, 27 % reported not taking any controller medication, and 14 % reported stopping controller treatment for 3 months or longer the last time they stopped. Many patients considered asthma well controlled if each year they had only two urgent doctor visits (50 %), three or four exacerbations (60 %), and/or one emergency room visit (41 %).Discussion This is the largest survey of patients with asthma in Europe and Canada in more than a decade.Conclusion In 2010, many surveyed patients in Europe and Canada reported features indicating uncontrolled asthma, yet the majority believed they were well controlled, indicating that they had low expectations of long-term asthma management. Use of controller medications was substantially less than recommended in treatment guidelines.
