Clinical Response Predictive Model for Omalizumab in Moderate-to-Severe Asthma Patients

Objective. Our study aimed to develop a predictive model for evaluating the clinical response of omalizumab treatment in moderate-to-severe asthma patients. Methods. This single-center, prospective study collected patients who meet the diagnostic criteria for moderate-to-severe bronchial asthma set by the National Asthma Prevention and Treatment Group in 2016 in the first hospital affiliated with Soochow University. Patients recruited were treated with omalizumab once per four weeks; at the beginning of each injection, blood eosinophils and the level of total serum IgE (IU/mL) were tested. After four injections of omalizumab, asthma control test (ACT), the 15-item Mini Asthma Quality of Life Questionnaire (MiniAQLQ), global treatment effectiveness (GETE), and lung function of all patients were evaluated in the 16th week. We used the selection operator method to build a logistic model and evaluated the clinical response of omalizumab in these patients. Results. This study included 108 moderate-to-severe patients (aged 39.86 ± 14.59 years). Eighty-nine patients finished treatment for 16 weeks, and 74 patients (83.1%) had an excellent or good response. The serum level of total IgE increased significantly after injection of omalizumab, while blood eosinophils count decreased significantly from baseline. Using the GETE as a clinical outcome, several clinical variables were significant predictors of clinical response. The corrected AUC and Brier scores were 0.872 and 0.111, which showed good discrimination. Significant variables included age, weight, family allergic history, acute exacerbations, the ratio of total serum IgE level at the 4th week to the baseline level, forced expiratory volume in one second/forced vital capacity (FEV1/FVC), and commodities of rhinitis. Using the improvement in maximal expiratory flow 25% of the measured value to the predicted value (MEF25%pre) as clinical outcome, the significant variables included weight, duration of asthma, use of oral corticosteroids (OCS), total serum IgE level at the 4th week, and history of rhinitis. Its corrected AUC and Brier scores were 0.674 and 0.225 after internal validation. Conclusion. Omalizumab treatment remarkably improved asthma control and pulmonary function in Chinese patients with moderate-to-severe asthma. The response prediction model we developed provides convenient approaches to help identify better clinical response patients to omalizumab treatment.

Increased adiposity to muscle ratio and severity of sinusitis affect quality of life in asthma—Computed tomographic analysis—

BackgroundDeteriorated sinusitis and increased adiposity relative to muscle mass may affect the quality of life(QoL) in patients with asthma. However, whether these effects are observed regardless of intra-pulmonary pathology is unknown. ObjectivesTo evaluate the correlation of the cross-sectional ratio of abdominal visceral fat (VF) to erector spinae muscle (ESM) and sinus findings based on Lund-Mackey scoring system (LMS) on computed tomography (CT) with the impaired score of the Asthma Quality of Life Questionnaire (AQLQ), regardless of airway and parenchymal disease, in patients with asthma. MethodsParticipants from the Hokkaido-based severe asthma cohort who had completed AQLQ and CT examination at the entry. The participants were divided into high (highest) and low (other quartiles) groups based on the extra-pulmonary indices. The multivariate analysis examined the association of VF/ESM for the adiposity-to-muscle ratio, LMS with AQLQ, after adjusting for the airway fractal dimension for airway index, %low attenuation volume for parenchymal index. ResultsNo significant differences were observed in VF/ESM and LMS in terms of sex. The AQLQ score in the high VF/ESM group and high LMS group was lower than those in low VF/ESM group and low LMS group (N:Male/Female, 63/100). High VF/ESM (estimate [95% confidence interval], (-0.43[-0.61,-0.25]) and high LMS scores (-0.22(-0.41, -0.03)) were associated with low AQLQ scores, adjusted for age, body mass index, smoking status, blood eosinophil counts, and intra pulmonary CT indices. ConclusionsIncreased VF relative to ESM mass and high LMS may deteriorate asthma related QoL, regardless of intra-pulmonary disease.

The Fractional exhaled Nitric Oxide (FeNO)- test as add-on test in the diagnostic work-up of asthma: a study protocol.

Asthma is a common disease characterized by chronic inflammation of the lower airways, bronchial hyperactivity, and (reversible) airway obstruction. The Global Initiative of Asthma Guideline recommends a flowchart to diagnose asthma with first-step spirometry with reversibility and a bronchial challenge test (BPT) with histamine or methacholine as a second step [1]. The BPT is considered burdensome, time-consuming for patients and staff, can cause side effects, and is expensive. In addition, this test strongly encumbers lung function capacity. Elevated Nitric Oxide (NO) is associated with airway eosinophilic inflammation in asthma patients and can be measured in exhaled air with the Fractional exhaled (Fe) NO-test. This low-burden FeNO-test could be used as an 'add-on' test in asthma diagnostics [2, 3]. This multi-center prospective study (Trial number: NCT06230458) compares the 'standard asthma diagnostic work-up' (spirometry with reversibility and BPT) to the 'new asthma diagnostics work-up' (FeNO-test as an intermediate step between the spirometry with reversibility and the BPT), intending to determine the impact of the FeNO-based strategy, in terms of the number of avoided BPTs, cost-effectiveness and reduced burden to the patient and health care. The cost reduction of incorporating the FeNO-test in the new diagnostic algorithm will be established by the number of theoretically avoided BPT. The decrease in burden will be studied by calculating differences in the Visual Analogue Scale (VAS) -score and Asthma Quality of Life Questionnaire (AQLQ) -score after the BPT and FeNO-test with an independent T-test. The accuracy of the FeNO-test will be calculated by comparing the FeNO-test outcomes to the (gold standard) BPTs outcomes in terms of sensitivity and specificity. The intention is to include 171 patients. The local medical ethics committee approved the proposed study and is considered a low-burden and risk-low study. The local medical ethics committee registration number: R23.005. Strengths: This is the first study that investigates the value of the FeNO-test (cut off ≥ 50 ppb) as an add-on test, to determine the impact of the FeNO-based strategy, in terms of the number of avoided BPTs, cost-effectiveness, and reduced burden on the patient and health care. High FeNO levels may also be observed in other diseases such as eosinophilic chronic bronchitis and allergic rhinitis. The FeNO-test can be used to rule in a diagnosis of asthma with confidence, however, due to the poor sensitivity it is not suitable to rule out asthma.

Physical Activity and Sedentary Behavior as Treatable Traits for Clinical Control in Moderate-to-Severe Asthma

Physical activity and sedentary behavior are treatable traits that may impact asthma control in distinct manners, but this impact remains poorly understood. To evaluate the influence of physical activity and sedentary behavior on clinical control in adults with moderate-to-severe asthma. This cross-sectional multicentric study included 426 individuals with moderate-to-severe asthma. Assessments included physical activity and sedentary time (actigraphy), clinical asthma control (Asthma Control Questionnaire [ACQ]), quality of life (Asthma Quality of Life Questionnaire [AQLQ]), anxiety and depression symptoms (Hospital Anxiety and Depression Scale [HADS]), anthropometric data, and lung function. Participants were grouped according to physical activity levels and sedentary behavior. Participants who walked ≥7,500 steps/day presented better ACQ scores than those who walked <7,500 steps/day (p<0.05), independent of sedentary status. The percentage of patients with controlled asthma was higher in the active/sedentary (43.9%) and active/nonsedentary (43.8%) groups than in the inactive/sedentary (25.4%) and inactive/nonsedentary (23.9%) groups (p<0.02). The likelihood of having uncontrolled asthma according to the treatable traits of physical inactivity (odds ratio [95% CI]: 2.36 [1.55-3.59]), higher anxiety (2.26 [1.49-3.42]), and depression symptoms (1.95 [1.28-2.95]) was significant (p≤0.002). Obesity and sedentary time were not associated with asthma control. Our results show that ≥7,500 steps/day is associated with better asthma control independent of sedentary time in adults with moderate-to-severe asthma. Physical inactivity, anxiety, and depression symptoms are associated with higher odds of uncontrolled asthma. These results suggest that interventions should mainly focus on increasing physical activity rather than reducing sedentary time.

Health-Related Quality of Life of Asthmatic Patients in Al-Baha City, Saudi Arabia.

Introduction According to disability-adjusted life years (DALY), bronchial asthma (BA) is rated 28th among the top causes of disease burden globally and among the most significant reasons for years lived with disability. Internationally, 300 million people have asthma, and another 100 million individuals may develop it by 2025. In Al-Baha City, where environmental factors such as dust and pollen levels can exacerbate asthma symptoms, understanding and addressing the health-related quality of life of asthmatic patients is crucial. Understanding the health-related quality of life of asthmatic patients can inform public health policies and initiatives aimed at reducing environmental triggers and promoting better asthma management in the city. Objectives The study aims to assess the impact of asthma regarding physical, emotional, and social activities that affect health-related quality of life. Subjects and methods A cross-sectional study was conducted from January 2023 to May 2023 at King Fahad Hospital in Al-Baha City, Saudi Arabia. The study used a Mini Asthma Quality of Life Questionnaire that measures physical, emotional, and social activities that affect health-related quality of life. Results One hundred and fifty-one out of 185 participants responded, yielding a response rate of 81.6%. The average age of the participants was 52, with a standard deviation of 15.4 years. Participants' responses regarding symptoms related to the environment during the last two weeks indicated "all the time" experiencing feeling bothered by or having to avoid cigarette smoke (n=104, 69%) and dust (n=92, 61%) in the environment. Moreover, considering emotion-related symptoms, 54% reported they did not feel afraid of not having their asthma medication available. Similarly, 46% reported never feeling frustrated because of asthma, whereas 3.3% of the participants documented hardly ever feeling frustrated. Regarding social activity limitations, 44 individuals (29%) reported no limits in these activities, while 43 (28%) reported being completely limited. While there were limitations in work-related activities, 42 participants (28%) reported no restrictions, whereas 34 (23%) reported being completely limited. Conclusion The study findings highlight a concern about suboptimal asthma control and the need to attain more satisfactory levels of asthma management.

Efficacy of bronchial thermoplasty in a patient panel with uncontrolled severe persistent asthma

Background Bronchial thermoplasty (BT) is an approved procedure to manage uncontrolled severe persistent asthma. Many insurance providers are reluctant to pay for BT without proven benefit among their specific patient panel. Objective Determine if BT is effective in a panel patient panel with uncontrolled severe persistent asthma. Study design and methods This was an unblinded prospective study of adult subjects with uncontrolled severe persistent asthma who underwent BT. Outcomes were assessed at baseline and then 3-, 6-, 12-, 18- and 24-months post-BT. The primary metric was an improved Asthma Quality of Life Questionnaire (AQLQ) score. Other metrics included improved Asthma Control Test (ACT), peak expiratory flow rates (PEFR), spirometry, fractional excretion of nitric oxide (FeNO), number of unscheduled medical visits, and lost days of work/activity. Respiratory adverse events were assessed during the BT treatment period and at each post-BT visit. Results Twenty-nine subjects completed the study; the median interquartile range (IQR) age was 47 (42-61), and the majority were female (69%), white (93%), and non-Hispanic (90%). After BT, mean (±std) AQLQ scores improved by 1.6(±1.1) at 3 months (p < 0.0001), 1.6(±1.2) at 6 months (p < 0.0001), 1.4(±1.0) at 12 months (p < 0.0001), 1.8(±1.1) at 18 months (p < 0.0001), and 1.6 (±1.5) at 24 months (p < 0.0001). There were significant improvements in ACT, PEFR, unscheduled medical visits and lost days of work and activity. Spirometry and FeNO metrics were unchanged. The average cost for subjects completing all 3 BT procedures was approximately $15,000. Conclusion BT is an effective adjunctive therapeutic modality in subjects with uncontrolled severe persistent asthma.

Can an educational intervention in the context of inpatient pulmonary rehabilitation improve asthma self-management at work? A study protocol of a randomized controlled trial

BackgroundAsthma self-management (e.g., trigger avoidance or correct medication use) is a cornerstone of therapy. Its successful implementation in everyday working life is determined by psychosocial working conditions, in particular by support from superiors and colleagues and the job decision latitude (i.e., when and how to carry out which tasks). To empower individuals with asthma to modify their working conditions, employees need to use certain communication skills and acquire specific knowledge. Both could be taught as part of patient education during pulmonary rehabilitation. Therefore, the aim of the planned study is the development and multicentre implementation of an education module for individuals with asthma during their rehabilitation and to generate evidence on its effectiveness.MethodsParticipants (n ≥ 180) will be recruited, randomized into an intervention and a control group, trained and surveyed in two rehabilitation clinics. The intervention group will receive the supplementary patient education module “Asthma and Work” while the control group will participate in a program on " Eating behaviour” (both 2 × 50 min). The effectiveness of the intervention will be examined based on pre-post measurements (T1 and T2) and a 3-month follow-up (T3). We will consider behavioural intention (T2) and asthma self-management at work (T3) as primary outcomes. Secondary outcomes will include self-management-related knowledge, self-efficacy, number of sick days, number of exacerbations, asthma control (Asthma Control Test), asthma-related quality of life (Marks Asthma Quality of Life Questionnaire), and subjective employment prognosis (Brief Scale Measuring the Subjective Prognosis of Gainful Employment). The pre-post comparisons are to be evaluated using univariate analyses of covariance.DiscussionImproving asthma self-management at work could increase the work ability and social participation of employees with asthma. This could reduce costs, e.g. in terms of asthma-related sick leave.Trial registrationGerman Clinical Trials Register (ID: DRKS00031843)

Evaluation of the effectiveness of Tadalafil on improving pulmonary function and asthma severity in severe asthmatic patients: a randomized controlled trial study

Phosphodiesterase inhibitors elevate the levels of cyclic adenosine monophosphate and cyclic guanosine monophosphate, which have been associated with various anti-inflammatory effects that can help alleviate asthma symptoms. This study aims to assess the impact of Tadalafil, a selective phosphodiesterase inhibitor, on pulmonary function in patients with asthma. This study was a randomized, double-blind clinical trial conducted in 2021 at Imam Khomeini Hospital in Ahvaz, Iran. The study enrolled 44 patients with severe asthma, who were divided equally into a Tadalafil group and a placebo group. The Tadalafil group received 20 mg/day of Tadalafil, while the placebo group received a placebo at the same dose. The patients' spirometry tests, asthma quality of life questionnaire, 6-minute walk distance, and quality of life were measured at the beginning of the study and one month later. The study results indicated that there was no statistically significant difference between the Tadalafil group and the placebo group in terms of pulmonary parameters (p>0.05). Furthermore, the scores for patients' quality of life (p=0.167) and the 6-minute walk test (p=0.148) at the end of the study did not show any statistically significant improvement compared to the placebo group. Results showed that the use of Tadalafil (20 mg) once daily for one month in patients with severe asthma did not affect clinical and laboratory outcomes.

Research on the Impact of Breathing Exercises and Aerobic Exercises on Quality of Life in Patients with Bronchial Asthma: A Comparative Study

Background: Asthma is defined as a chronic inflammatory disorder of airways characterized by reversible airflow obstruction causing cough, wheeze, chest tightness and shortness of breath Crompton et al7Asthmatic attacks are set up by exposure to specific allergens such as house dust mite, pollen and animal dander. Some other factors are exercise particularly running, dyes, air pollution, infection, cigarette smoke, dry inhaled air, certain foods such as fish, eggs, yeast, and wheat which presumably reach the bronchi via blood stream. There is noticeable increase in healthcare burden from asthma in several areas of world .The most frequently mentioned aims of breathing exercises are to ‘normalize’ breathing pattern by adopting a slower respiratory rate with longer expiration and reduction of hyperventilation and hyperinflation. Training also frequently involves encouraging nasal breathing and a diaphragmatic breathing pattern.AQLQ AND SF36 questionnaire was used as outcome measure.Methods: The sample size of this study was 30 subjects with 15 subjects in each group. The group A was given breathing exercises interventions and group B was given aerobic exercises intervention. A written consent was taken from each before their participation into the study. Asthma Quality of Life Questionnaire (AQLQ) and SF-36 quality of life Questionnaire of both the groups were taken in 0 week and both groups were assigned treatment interventions and after 3 weeks the AQLQ and SF-36 quality of life questionnaire has been repeated.The independent variables in the study were Aerobic Exercises and Breathing Exercises.Conclusion: The breathing exercise intervention was effective in improving the quality of life in asthmatic patients.The aerobic exercise intervention was also effective in improving the quality of life in asthmatic patients.However, the quantum of reduction in lung obstruction and therefore, the overall improvement in quality of life found to be more significant with the aerobic exercise intervention than breathing exercise intervention. Thus,a combination of the breathing exercises and aerobic exercise should be incorporated into the pulmonary rehabilitation program of the asthmatic patients.

Long-term efficacy of house dust mite sublingual immunotherapy on clinical and pulmonary function in patients with asthma and allergic rhinitis

BackgroundA previous study reported that house dust mite (HDM) sublingual immunotherapy (SLIT) for 48 weeks was effective as add on treatment for allergic asthma; however, data regarding its long-term efficacy is scarce. ObjectiveThis open-label extension study aimed to evaluate the effect of HDM SLIT on asthma control, pulmonary function, airway inflammation and remodeling throughout the 5-year treatment period. MethodsA total of 140 patients with asthma and allergic rhinitis sensitized to HDM were randomized to receive either drugs alone or drugs plus SLIT for 5 years. Asthma Control Questionnaire (ACQ)-5, Asthma Quality of Life Questionnaire (AQLQ), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), spirometry, quantitative computed tomography, and type 2 biomarkers were assessed. ResultsAn improvement in the ACQ-5, AQLQ, and RQLQ scores was observed in the SLIT group compared with the control group. HDM SLIT increased lung function and reduced the percentage of airway wall area (WA/Ao). The levels of fractional exhaled nitric oxide (FeNO), blood eosinophil, serum specific IgE (s-IgE) for HDM, and total IgE decreased and were sustained during the 5 years. The change in type 2 biomarkers correlated with change in AQLQ score. Based on receiver operating characteristic (ROC) analysis for predicting responders, the area under the ROC curve in FEV1% predicted, WA/Ao, FeNO, and s-IgE was high. Multivariate regression analysis showed that the strongest predictor of responders was FeNO. ConclusionsHDM SLIT continued to provide sustained efficacy, improve lung function, and prevent progression of airway inflammation and remodeling in asthma through to year 5.

Asthma–COPD overlap syndrome among smoker subjects with asthma: A cross-sectional study

This study aimed to assess the prevalence of asthma–chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) in asthmatic outpatients with smoking exposure (smokers or ex-smokers with ≥10 pack-year history) and to evaluate quality of life (QoL) and adherence among the study sample. This cross-sectional study was conducted at outpatient respiratory clinics in governmental hospitals in Jordan. Asthmatic outpatients were interviewed to assess their spirometric readings, patients’ adherence, and patients’ QoL [using the Mini Asthma QoL questionnaire (MiniAQLQ)]. The prevalence of ACOS was found to be 33% among asthmatic smoker patients in the outpatient setting (n = 65 out of 200 subjects with asthma-diagnosed patients recruited into the study). For subjects with ACOS, 47.7% of them were older than 60 years old. Smoking history for more than 30 years was prevalent among most subjects with ACOS (67.7%). The MiniAQLQ average score was found to be low (mean ± SD = 3.23 ± 1.01, score out of 7) and similarly for patients’ adherence to their treatment modalities (mean ±SD = 1.76 ± 1.2, score out of 6). A significant positive relationship between adherence to treatment and QoL was found among subjects with ACOS (correlation coefficient = 0.171, p-value = 0.018). In conclusion, a moderate prevalence of ACOS was estimated among asthmatic smoker patients. Low levels of QoL and adherence to treatment were significantly correlated.

Asthma control and sputum eosinophils in adult patients: a cross-sectional study in southern Brazil

Asthma control and health related quality of life are an important goal of asthma management, but their association with sputum eosinophilic inflammation has been less firmly established. To investigate the relationship of asthma control and quality of life with sputum eosinophils in clinical practice. Cross-sectional study with a convenience sample, including patients with asthma, aged between 18 and 65 years, attending to outpatient clinic. Patients underwent sputum induction, pulmonary function tests, Juniper’s Asthma Quality of Life Questionnaire (AQLQ), Asthma Control Test (ACT), Global Initiative for Asthma (GINA) criteria for evaluation of asthma control and severity of the disease, blood count analysis, serum IgE and cutaneous prick test. Sputum sample was considered as eosinophilic if the percentage of eosinophils was ≥ 3%. A total of 45 individuals were enrolled, 15 with eosinophilic sputum (≥ 3% eosinophil cells) and 30 with non-eosinophilic sputum (< 3% eosinophil cells). There were no association of ACT an AQLQ scores with sputum eosinophilia (p > 0.05). This study suggested that the finding of sputum eosinophilia was not related to asthma control neither with health-related quality of life in patients with severe asthma.

Use of Quantitative CT Imaging to Identify Bronchial Thermoplasty Responders

Bronchial thermoplasty (BT) is a treatment for patients with poorly controlled, severe asthma. However, predictors of treatment response to BT are defined poorly. Do baseline radiographic and clinical characteristics exist that predict response to BT? We conducted a longitudinal prospective cohort study of participants with severe asthma receiving BT across eight academic medical centers. Participants received three separate BT treatments and were monitored at 3-month intervals for 1 year after BT. Similar to prior studies, a positive response to BT was defined as either improvement in Asthma Control Test results of≥ 3 or Asthma Quality of Life Questionnaire of≥ 0.5. Regression analyses were used to evaluate the association between pretreatment clinical and quantitative CT scan measures with subsequent BT response. From 2006 through 2017, 88 participants received BT, with 70 participants (79.5%) identified as responders by Asthma Control Test or Asthma Quality of Life Questionnaire criteria. Responders were less likely to undergo an asthma-related ICU admission in the prior year (3%vs25%; P= .01). On baseline quantitative CT imaging, BT responders showed less air trapping percentage (OR, 0.90; 95%CI, 0.82-0.99; P= .03), a greater Jacobian determinant (OR, 1.49; 95%CI, 1.05-2.11), greater SD of the Jacobian determinant (OR, 1.84; 95%CI, 1.04-3.26), and greater anisotropic deformation index (OR, 3.06; 95%CI, 1.06-8.86). To our knowledge, this is the largest study to evaluate baseline quantitative CT imaging and clinical characteristics associated with BT response. Our results show that preservation of normal lung expansion, indicated by less air trapping, a greater magnitude of isotropic expansion, and greater within-lung spatial variation on quantitative CT imaging, were predictors of future BT response.

Effect of Bicycle Ergometer Training and Nordic Walking Training on Improving Functional Exercise Capacity in Asthma Patients.

Introduction Asthma is a chronic respiratory condition characterized by inflammation of the airway leading to breathlessness. Exercise training has been recognized as a valuable component in the management of asthma, enhancing lung function and overall well-being. Bicycle ergometer training and Nordic walking are two distinct forms of exercise that have been shown to improve cardiovascular fitness and respiratory function. Despite the potential benefits of these exercises, limited research directly compares their efficacy in improving functional capacity specifically in asthma patients. The study thus aims to address this gap by providing personalized, tailored exercise programs for asthma patients. Methods A single-blinded experimental study using a simple random sampling method was conducted. A sample of 40 subjects was recruited for the study based on inclusion and exclusion criteria and were assigned into two groups. Group A subjects were trained with a bicycle ergometer and Group B subjects were trained with Nordic walking. The intervention was given to both groups for 12 weeks. The outcome measures used were the six-minute walk test, Modified Borg Scale, and Mini Asthma Quality of Life Questionnaire. Results A baseline analysis of outcome measures was done, which was followed up by a post-test analysis after 12 weeks. Pre-test and post-test data were compared using a paired t-test.Intergroup analysis was done by an independent t-test. Both groups showed significant improvement in post-test results. On comparing the two groups, Group A showed significant improvement as compared to Group B. Conclusion The study concludes that bicycle ergometer training is effective in improving functional capacity and enhancing the quality of life in asthma patients.

Quality of Life and Its Accompanying Factors among Adult Female Patients with Chronic Bronchial Asthma

Background: Asthma is a well-known chronic respiratory disease and a common global health problem. In Bangladesh, more than 100 million people are suffering from cough and shortness of breath. Patients with a known diagnosis of asthma are an important determinant of reduced quality of life. Objectives: To determine the quality of life and its accompanying factors among adult female patients with chronic bronchial asthma. Materials and methods: This cross-sectional study was conducted at the National Institute of Diseases of the Chest and Hospital, Dhaka from January to December 2021. Total eighty-five diagnosed adult female bronchial asthma patients were included in this study. Data were collected by face-to-face interviews with a semi-structured questionnaire using the Asthma Quality of Life Questionnaire (AQLQ) and Asthma Control Test (ACT) scale. The checklist was used for collecting data by reviewing medical records. Results: Among all the patients, the mean (±SD) age was 39.74±8.98 years and the highest frequency 48 (56.5%) patient’s age were in the 31-45 years group. In this study, the mean AQLQ score was 3.55 so, it indicated a moderate degree of impairment of quality of life and the most affected domain was environmental stimuli. Among all patients, 52 (61.2%) had partially controlled asthma. The study finding showed that the level of impairment of quality of life decreased with the increase of age (p=0.001). Uncontrolled asthma was associated with a lower quality of life (p=0.001). The low educational level 25 (29.4%), residing in rural areas 26 (30.6%) and having comorbidity 44 (51.8%) adversely affected the level of AQLQ. Conclusion: Now a day’s chronic bronchial asthma is a major public health issue, and it affects the quality of life. So, the current study may contribute to the prevention of worsening the level of impairment of quality of life in bronchial asthma patients. Eastern Med Coll J. July 2023; 8 (2):61-67

Assessing the validity and reliability of the Arabic versions of Mini Asthma Quality of life questionnaire and Asthma Control Test in adult patients with asthma: A factor analysis study

Background and objectiveAsthma is a common disease that has a significant influence on patients’ quality of life. Although Arabic tools for assessing symptom control and quality of life in individuals with asthma are available, no sufficient studies have evaluated the validity of these tools. Therefore, the aim of the current study was to validate the Arabic version of these tools. MethodsExploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted on the Arabic versions of the Asthma Control Test (ACT) and Mini Asthma Quality of Life Questionnaire (Mini AQLQ). ResultsA total of 314 participants (70.1 % females) were enrolled in the current study. The mean age of the participants was 51.47 (±16.37). EFA suggested a three-factor model for Mini AQLQ and a one-factor model for ACT, which was confirmed by CFA analyses. High correlations were found between spirometric values and ACT and Mini AQLQ scores, indicating good concurrent validity. The area under the curve produced by the Roc curve was 0.861 (p < 0.001), and the most suitable cut-off point was 4.741. ConclusionAll analyses conducted showed that the Arabic versions of both Mini AQLQ and ACT are reliable and valid and can be administered to adults with asthma. The application of these validated instruments will improve the management and diagnosis of asthma in Arab countries.

Work-Related Asthma and Its Impact on Quality of Life and Work Productivity

The impact of work-related asthma (WRA) on quality of life (QoL) and work productivity remains largely neglected/uncertain despite its high prevalence. To investigate the association of WRA with QoL and work productivity as compared with subjects with non-WRA and those without asthma and rhinitis. A cross-sectional survey was carried out among workers during their periodic occupational health visit in Belgium. The Mini Asthma Quality of Life Questionnaire, the 8-item Medical Outcome Study Short Form instrument, and the Work Productivity and Activity Impairment-General Health questionnaire were administered. Survey participants were divided into 3 groups: (1) WRA (current asthma with ≥2 respiratory symptoms at work; n= 89); (2) non-WRA (current asthma without work-related respiratory symptoms; n= 119); and (3) the reference group (no asthma and no lower respiratory, nasal, or eye symptoms; n= 815). Associations of QoL and work productivity with WRA were evaluated by multivariable regression analyses. WRA and having poor asthma control were significantly associated with lower global Mini Asthma Quality of Life Questionnaire scores compared with non-WRA. Asthmatic subjects had significantly lower physical and mental health component scores of the 8-item Medical Outcome Study Short Form instrument and overall work productivity compared with the reference group, with greater impairment in workers with WRA than in those without WRA. Moreover, workers with WRA had higher percentages of doctor visits and income reduction because of respiratory symptoms than those with non-WRA. Work-related rhinitis and depression were associated with reduced QoL, independent of the effect of WRA. WRA should be managed comprehensively to reduce the worsening of QoL and work productivity of those affected.

Quality of life and its influencing factors on children with asthma in China: a comparative study before and during the COVID-19 pandemic

Objective This study compares the level of quality of life (QoL) and its influencing factors on children with asthma before and during the COVID-19 pandemic. Methods The study carried out cross-sectional surveys on children with asthma and their parents in China before and during the epidemic. Data were collected using a demographic questionnaire, the Family Management Scale for Children with Asthma (FMSCA), and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Participants from before the epidemic were matched by their propensity score in a 1:1 ratio with individuals from during the epidemic. The level of QoL of children with asthma was subsequently analyzed. Both univariate analysis and multiple linear regression were employed to identify the influencing factors. Results Compared to their level before the epidemic, the total score of PAQLQ and its three dimensions decreased during the epidemic. Regression analysis revealed that before the epidemic, the total score of PAQLQ was significantly associated with follow-up visits, attendance of asthma lectures, and the total score of FMSCA (p < 0.05). During the epidemic, the total score of the PAQLQ was significantly associated with three dimensions of the FMSCA (future expectation, children identity, and views of condition), and two classifications of the family management styles (FMS) (enduring and accommodating) (p < 0.05). Conclusion The QoL of children with asthma deteriorated during the epidemic. Influencing factors changed during the epidemic, with more emphasis on the family environment. Future intervention strategies need to take into account the development of interactions between children and environmental forces.

Efficacy of Bhramari pranayama and Om chanting on asthma control, quality of life, and airway inflammation in asthmatic children: an open-label randomized controlled trial

Objectives To explore the efficacy of combination of Bhramari pranayama and om chanting as an adjunct to standard pharmacological treatment on asthma control, quality of life, pulmonary function, and airway inflammation in asthmatic children. Methods Children (n = 110; 8–15 years) with uncontrolled or partly controlled asthma were recruited from the Pediatric Chest Clinic of All India Institute of Medical Sciences, New Delhi. Eligible participants were randomized to either home-based online Bhramari pranayama and om chanting plus standard treatment (YI + ST) group, or standard treatment (ST) alone group. Primary outcome measures were 12-week change in level of asthma symptom control; asthma control questionnaire (ACQ) score, spirometry indices, impulse oscillometry parameters, and pediatric asthma quality of life questionnaire (PAQLQ) score. Secondary outcome was a change in fractional exhaled nitric oxide (FeNO) levels at 12 weeks. Beginning from the enrollment, every participant was evaluated at 0, 2, 6, and 12 weeks. Results After 12 weeks of intervention, higher proportion (68.2%) of children were found to have controlled asthma symptoms in the YI + ST group as compared to ST group (38.5%) according to per protocol analysis (p = 0.03). When compared to ST group, children in YI + ST group showed significantly lower ACQ score, higher PAQLQ score and reduced FeNO levels. No significant changes were observed for the lung function parameters. Conclusion Children practicing Bhramari pranayama and om chanting for 12 weeks have better asthma symptom control, quality of life, and reduced airway inflammation than those taking standard pharmacotherapy alone.

Adult Severe Asthma Registries: A Global and Growing Inventory.

The International Severe Asthma Registry (ISAR; http://isaregistries.org/) uses standardised variables to enable multi-country and adequately powered research in severe asthma. This study aims to look at the data countries within ISAR and non-ISAR countries reported collecting that enable global research that support individual country interests. Registries were identified by online searches and approaching severe asthma experts. Participating registries provided data collection specifications or confirmed variables collected. Core variables (results from ISAR's Delphi study), steroid-related comorbidity variables, biologic safety variables (serious infection, anaphylaxis, and cancer), COVID-19 variables and additional variables (not belonging to the aforementioned categories) that registries reported collecting were summarised. Of the 37 registries identified, 26 were ISAR affiliates and 11 non-ISAR affiliates. Twenty-five ISAR-registries and 4 non-ISAR registries reported collecting >90% of the 65 core variables. Twenty-three registries reported collecting all optional steroid-related comorbidity variables. Twenty-nine registries reported collecting all optional safety variables. Ten registries reported collecting COVID-19 variables. Twenty-four registries reported collecting additional variables including data from asthma questionnaires (10 Asthma Control Questionnaire, 20 Asthma Control Test, 11 Asthma Quality of Life Questionnaire, and 4 EuroQol 5-dimension 5-level Questionnaire). Eight registries are linked to databases such as electronic medical records and national claims or disease databases. Standardised data collection has enabled individual severe asthma registries to collect unified data and increase statistical power for severe asthma research irrespective of ISAR affiliations.
