    Full Text Available Recent asthma deaths were examined from yearly reports of the Ministry of Health, Labor and Welfare of Japan and from reports published by the Japan Asthma Death Investigation Committee on 811 deaths over the period 1992–2000. The rate and number of recent asthma deaths in Japan have been decreasing rapidly. Most asthma deaths were of patients aged 70–90 years and there has been a marked trend for increased asthma deaths in the elderly. As for the circumstances surrounding the deaths, sudden death, unstable sudden aggravation and intermittent aggravation were mainly noted. Respiratory infections, fatigue and stress were the major courses of fatal attacks contributing to deaths due to asthma. Many of the patients who died from asthma had been diagnosed as having as moderate to severe asthma and many had non-atopic asthma. There are some reports that suggest that the recent decrease in asthma deaths in Japan is correlated with the use of inhaled cortico- steroids.

    Omalizumab is effective in children with severe asthma, but its impact on medical cost in Japan is not clear. We evaluated the impact of omalizumab on medical cost by comparing the pre- vs post-omalizumab-initiation medical costs of 12 children with severe asthma who received omalizumab for 2 years, and calculating incremental cost-effectiveness ratio for omalizumab therapy. Health outcome was measured as hospital-free days (HFD). The median total medical costs and medication fee per patient increased significantly after omalizumab initiation because of the high cost of omalizumab. The median hospitalization fee per patient, however, decreased significantly after omalizumab initiation due to reduction in hospitalization. Omalizumab led to an estimated increase of 40.8 HFD per omalizumab responder patient per 2 years. The cost was JPY 20 868 per additional HFD. Omalizumab can therefore reduce hospitalization cost in children with severe asthma in Japan. © 2016 Japan Pediatric Society.

    The asthma control questionnaires used in Japan are Japanese translations of those developed outside Japan, and have some limitations; a questionnaire designed to optimally evaluate asthma control levels for Japanese may be necessary. The present study was conducted to validate the Japan Asthma Control Survey (JACS) questionnaire in Japanese asthma patients. A total of 226 adult patients with mild to severe persistent asthma were enrolled and responded to the JACS questionnaire, asthma control questionnaire (ACQ), and Mini asthma quality of life questionnaire (Mini AQLQ) at Weeks 0 and 4. The reliability, validity, and sensitivity/responsiveness of the JACS questionnaire were evaluated. The intra-class correlation coefficients (ICCs) were within the range of 0.55-0.75 for all JACS scores, indicating moderate/substantial reproducibility. For internal consistency, Cronbach's alpha coefficients ranged from 0.76 to 0.92 in total and subscale scores, which were greater than the lower limit of internal consistency. As for factor validity, the cumulative contribution ratio of four main factors was 0.66. For criterion-related validity, the correlation coefficients between the JACS total score and ACQ5, ACQ6, and Mini AQLQ scores were -0.78, -0.78, and 0.77, respectively, showing a significant correlation (p asthma control status in a higher number of patients.

    People living in Japan were affected in various ways after the Great East Japan earthquake of March 11, 2011. A 52-year-old female asthma patient not directly affected by the disaster experienced a decrease in peak expiratory flow (PEF) immediately after the earthquake. Despite increasing the inhaled and oral corticosteroid doses, her PEF did not recover. One month later, her PEF level abruptly returned to normal with minimal medications, which were previously ineffective, and the asthma-related symptoms vanished. The stabilization of her state of mind and actual social state seemed to be a part of the reason for the patient's recovery.

    Full Text Available Abstract Background The incidence of chronic obstructive pulmonary disease (COPD and bronchial asthma began increasing in early 1960s in the population of Yokkaichi-city (Mie Prefecture, Japan. The cause of the disease was sulfur oxide air pollution, and it is known as Yokkaichi Asthma. The pollution markedly decreased by the end of 1970s; no new cases have been reported since 1988. This study aimed at examining the late effects of air pollution on the health of Yokkaichi Asthma patients. Methods Mortality rate and life expectancy of patients, registered between 1965 and 1988, were investigated from 1975 through 2000. Results Mortality rates for COPD and asthma in patients from Yokkaichi-city were significantly higher than in the whole population of Mie Prefecture. For all ages (except for males between 80 and 84 years in 1985, the life expectancy of both males and females were significantly reduced in patients from Yokkaichi-city as compared with the whole population of Mie Prefecture. The potential gains in life expectancy excluding the mortality for respiratory diseases including COPD and asthma were larger for all ages in patients from Yokkaichi-city. Conclusion Mortality and life expectancy were adversely affected in patients from Yokkaichi-city, despite the fact that the air pollution problem has been already solved.

    Full Text Available Background. Treatment and management strategies for asthma in children are generally consistent internationally, but prescription of antiasthma drugs differs among countries. The objective of this study was to examine the prescribing patterns of antiasthma drugs, particularly controller medications, in children. Methods. A retrospective cohort study was performed in children with asthma using an administrative claims database in Japan. Results. A total of 1149 preschool-age and 3226 school-age children were identified. Leukotriene receptor antagonists were prescribed for about 80% of the children. Long-acting β-agonists were prescribed for 87.6% and 59.6% of preschool-age and school-age children, respectively, whereas prescriptions of inhaled corticosteroids had lower rates of 8.2% and 16.5%, respectively. In an examination of prescriptions at 1-month intervals, a relatively high number of children were prescribed bronchodilators without anti-inflammatory agents. Conclusion. Our findings suggest that asthma care for children in Japan can be improved through changes in drug prescriptions.

    Severe wind storms during spring in East Asia, called Asian dust storms (ADS), have been assessed in the past for their effect on health in Asian countries. Our objective was to study the ADS association with asthma symptoms in adult patients in Japan. We designed a telephone survey to assess ADS influence on upper and lower respiratory, ocular and cutaneous symptoms in 98 patients with adult asthma from April to May 2007. Peak expiratory flow (PEF) was also measured from February to May. Worsening lower respiratory symptoms were noted by 22 of 98 patients during ADS in April, when Japanese cedar pollen levels also increased. During ADS in May, however, Japanese cedar and cypress pollen levels were not elevated, 11 patients had worsening of lower respiratory symptoms. None required emergency treatment for the exacerbation. Lower respiratory symptoms worsening most were cough and sputum; this was more common in patients with allergic rhinitis or atopy than in those without (P storm. We found that ADS aggravated lower respiratory symptoms in adult patients with asthma, but this influence was mild.

    Full Text Available Asthma therapy including inhaled corticosteroids (ICS has been shown to be effective in many parts of the world, but its use is still limited in Japan. A 6-week, randomized, placebo-controlled, clinical trial was therefore undertaken to assess the efficacy of the ICS budesonide Turbuhaler (budesonide administered via the dry-powder inhaler Turbuhaler in patients in Japan with mild-to-moderate asthma. Prior to, and during, the study, all concomitant medications, except corticosteroid preparations, were allowed (i.e. all pre-study medication was to be maintained throughout the study. In total, 218 patients randomized to receive budesonide Turbuhaler 200 μg/day (n = 53, 400 μg/day (n = 55, 800 μg/day (n = 57 or placebo (n = 53 were included in the analysis. Due to the increased demand and interest for health economic data in Japan, this retrospective cost-effectiveness analysis reports on the economic impact of budesonide Turbuhaler compared with placebo (i.e. usual care, based on this clinical trial. At each dosage, budesonide Turbuhaler was significantly more effective than the placebo, according to the number of symptom-free and episode-free days. The number of emergency visits, days of lost production and days of hospitalization were all lower in the budesonide Turbuhaler groups, leading to significantly (P < 0.05 reduced total health-care and productivity costs compared with placebo. These findings were generally stable to sensitivity analysis. However, this reduction in costs will obviously have to be compared with the acquisition cost of budesonide Turbuhaler (which was excluded in the analysis as a price had not been determined when it becomes available on the market. Budesonide Turbuhaler, while improving the health of patients, could thus have a considerable impact on the costs of treating asthma in Japan, by shifting large hospital care costs towards relatively small out-patient medication costs.

    Japan is an aging society, and the number of elderly patients with asthma and chronic obstructive pulmonary disease (COPD) is consequently increasing, with an estimated incidence of approximately 5 million. In 2014, asthma-COPD overlap syndrome (ACOS) was defined by a joint project of Global Initiative for Asthma (GINA) committee and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) committee. The main aims of this consensus-based document are to assist clinicians, especially those in primary care or nonpulmonary specialties. In this article, we discussed parameters to differentiate asthma and COPD in elderly patients and showed prevalence, clinical features and treatment of ACOS on the basis of the guidelines of GINA and GOLD. Furthermore, we showed also referral for specialized investigations.

    We compared peripheral airway and lung parenchyma images among patients with asthma, chronic obstructive pulmonary disease (COPD) and healthy controls using high-resolution CT images taken by a multidetector-row CT scanner (Aquillion, Toshiba, Japan). CT images were saved as digital image and communication (DICOM) files and %low attenuation area (LAA) (<-960 Hounsfield Unit) was calculated with the imaging software. %LAA was significantly increased in patients with COPD (p<0.0001) and smokers with stable asthma (p<0.01) as compared with healthy controls. In stable asthma, mucous plugging in the airway sometime appeared, while during asthma exacerbation small nodules and mosaic pattern of peripheral lung field appeared. Since smoker's patients with asthma have hyper-secretion of sputum due to smoking, mucous plugging and airway inflammation may easily occur and consequently air trapping may increase. In the future, image diagnosis of peripheral airway should develop for early detection of airway diseases as a non-invasive examination. On the other hand, micro focus X-ray computed tomography system (Hitachi Medico Technology Co., Japan) can display CT images closely similar to the pictures of microscopic findings and it will be a useful tool to analyze radiologic-pathologic correlations of peripheral airways and lung parenchyma.

    Responses to the questionnaire on the diagnosis, patient education and management of asthma indicated that a reduced number of patients with severe asthma were seen in 1993 in both Pediatric and Internal Medicine Departments compared with 5 years before, despite the increase in total number of asthma patients in Japan. Specifiic IgE radioallergosorbent test (RAST measurements were frequently performed instead of skin testing for diagnosis, and eosinophil count and bronchodilator response served as an adjunct to the diagnosis. Patients were frequently asked detailed questions about aspirin-induced asthma, which accounted for 8.8, 2.2 and 1.5% of patients with asthma in the adult, schoolchildren (6–16 years and infant (≤ 5 years groups, respectively. In achieving ‘control of asthma’, first priority was given to coping with the symptoms in children aged 5 years or less and to enabling routine daily life activities in patients 6 years of age or older. Usefulness of peak flow measurements was widely recognized and a detailed plan for allergen avoidance (house dust was often given to patients.

    A high-dose administration of inhaled corticosteroid is effective in the majority of patients with bronchial asthma, but is often difficult to attain sufficient control in certain subsets of patients. Omalizumab has recently emerged as a promising drug for bronchial asthma. To assess its add-on effect we administered omalizumab to patients with uncontrolled atopic asthma for more than 16 weeks and gave them questionnaires. The study population comprised 9 patients with frequent asthmatic symptoms despite the administration of high-dose inhaled corticosteroid and other disease controllers. We scored disease control using the Asthma Health Questionnaire-33-Japan and the Asthma Control Test, and evaluated the frequencies of short-acting beta2-agonist use for rescue and drip infusion of theophyllines and/or systemic steroids in a retrospective fashion. Asthmatic scores were significantly improved after 16 weeks of omalizumab therapy. The frequencies of reliever use and drip infusion were also decreased. These trends were present even in patients in whom no aeroallergen-specific IgE antibodies were detected. No statistically significant side effects were observed. Our study confirmed the add-on effect of omalizumab based on evaluation by simple questionnaires. Further studies are needed to clarify whether omalizumab therapy is suitable for patients without specific IgE antibodies.

    For successful long-term asthma care, self-management education is a cornerstone. Little is known about associations between patients' interest in education, asthma control and care delivery. We compared patients' characteristics, asthma control and patients' perspective about asthma care in subjects with and without interest in asthma education. Moreover, we assessed reasons, why patients denied participating in asthma education. Baseline data of 223 patients with asthma (age 43 ± 12 years, 38% male, 58% non-smokers, 13% current smokers), who participated in a multicentre longitudinal controlled study, are reported. At baseline, patients completed the Asthma Control Test (ACT), the Patient Assessment Chronic Illness Care questionnaire (PACIC 5A) and stated their interest in an asthma education programme. Overall, 34% of all participants showed uncontrolled asthma. One hundred and twenty-five (56%) patients were interested in education. Compared to patients without interest, they were characterised by male gender (p = 0.013), worse asthma control (p < 0.001), and perception of lower quality of chronic asthma care delivery, in particular lower self-management support (p < 0.001). Main reasons for rejecting asthma education were having sufficient asthma knowledge, having only mild asthma, receiving adequate medical support and lack of time. More than half of the patients were interested in asthma education. Interest was associated with worse asthma control and lower receipt of care according to the Chronic Care Model. Considering these aspects, this approach may help to improve care quality and allow targeting interventions to those patients who are interested in becoming active participants in their care and who might benefit most.

    Psychological distress of patients with asthma may be reduced when they learned to live with their illness. Asthma can change the psychological and personality characteristics. We aim to investigate the psychological and personality characteristics of patients with asthma using MMPI (Minnesota Multiphasic Personality Inventory). Thirty-three adult patients with asthma (23 female and 10 male) and 20 healthy controls (14 females and 6 males) were enrolled in this study. Psychometric evaluation was made with the Turkish version of the MMPI. The patients were separated into two groups according to the duration of symptoms (recent-onset asthma introvert.

  16. Contesting asthma medication: patients' view of alternatives.

    There are few studies pertaining to asthma patients' views on complementary and alternative medicine (CAM). The driving question behind the study is why some asthma patients choose noncompliance to conventional western medicine and resort to other modalities, often deemed as being 'alternative,' 'complementary,' or 'integrated.' Does the patients' emancipation movement lead to greater awareness of the benefits of alternative medicine? Does the patients' identity as asthma sufferers play a role in their decision? Case studies based on semistructured interviews were conducted between June 2009 and January 2010 with 19 asthma patients in The Netherlands who have chosen complementary and alternative medicine (CAM). Patients were contacted through online forum of Dutch asthma patients' organization Astma Fonds. We have discovered that on the whole patients in the present study were well informed about risks and benefits of both prescribed and alternative medicines. We have argued that noncompliance to medical regime by some asthma patients can be explained by the rationality of their choice based on evidence of clinical trials of commonly assigned asthma medication as well as partial and anecdotal evidence of the benefits of CAM therapies. It is the patients themselves who, by invoking the same evidence-based dominant paradigm choose to address the conflict between protagonists of 'conventional,' western medicine and other modalities. The author argues that asthma patients' noncompliance with (Western) medical regime and choice for alternative medical treatment of asthma is a matter of rational choice informed by evidence-based awareness. This evidence-based rationality particularly refers here to the patients' awareness of the rather controversial results of clinical trials of commonly used asthma medicines, particularly those containing elements of budesonide (Pulmicort), an anti-inflammatory corticosteroid, and formoterol (Oxis, Foradil), a rapid-acting and long

    To elucidate whether there may be a higher morbidity threshold for African American versus white children to be referred to or seek asthma specialist care. Secondary analysis of registry data captured from children presenting for an initial routine outpatient asthma consultation. Parents completed standard survey instruments, and spirometry was conducted when deemed appropriate by the provider. Wilcoxon rank sum tests revealed that African American patients had been hospitalized twice as often and admitted to the intensive care unit or intubated significantly more than 1½ times more frequently than their white patient counterparts. t tests indicated African American patients' forced expiratory volume in 1 second (FEV1) percentage predicted was significantly worse than that of whites, but there was no significant difference for FEV1/forced vital capacity ratio. t tests suggested that African American patients had statistically worse asthma control than did white patients at the time of initial presentation to the pulmonologist, but there was no difference in the distribution of asthma severity categories. Multivariate regression models indicated that racial differences in parent education did not explain the disparities in asthma morbidity. African American patients had significantly worse asthma morbidity than their white counterparts, including higher rates of hospitalization and intensive care unit admission and poorer lung functioning. Given that receipt of asthma specialist care can improve those outcomes that are disparately experienced by African American children, methods of increasing their access to and use of asthma specialist care need to be developed.

    Objective was the evaluation of asthma control using the Asthma Control Test (ACT). The ACT was used to assess asthma control among patients with bronchial asthma visiting pulmonary clinics in 5 major tertiary care hospitals in Riyadh, Kingdom of Saudi Arabia. Each hospital had target of 300 patients to recruit over the period of the study from 1st September to 30th November 2006. The total number of patients studied was 1060 patients. Males constituted 442 (42%) and the females constituted 618 (58%), the median age was 38.56 years range 15-75. One-third of the patients had no formal education. The ACT score revealed uncontrolled asthma in 677 (64%), well controlled asthma in 328 (31%) and complete controlled in 55 (5%). There were no significant correlation between the age below 40 and above 40 years and level of asthma control p=0.12. However, the younger age group less than 20 had better control of asthma in comparison with older patients p=0.0001. There was significant correlation between level of asthma control and gender, males 44% had better asthma control than females (30%, p=0.0001). Control of bronchial asthma is still major concern in our population. Further studies are needed to explore the factors leading to poor asthma control. (author)

    How general practitioners (GPs) and patients perceive asthma control, and concordance between these perceptions, may influence asthma management and medication adherence. The aims of this study were to determine asthma prevalence in adult patients, measure patient asthma control and the correlation between GP and patient perceptions of asthma control or impact. A Supplementary Analysis of Nominated Data (SAND) sub-study of the Bettering the Evaluation and Care of Health (BEACH) program surveyed 2563 patients from 103 GPs. Asthma control was measured using the Asthma Control Questionnaire 5-item version (ACQ-5), and medication adherence by patient self-report. Survey procedures in SAS software and Pearson's correlation statistics were used. Asthma prevalence was 12.7% (95% confidence interval: 10.9-14.5), with good correlation between GP and patient perceptions of asthma control/impact, and with raw ACQ-5 scores. Grouped ACQ-5 scores showed higher levels of uncontrolled asthma. Medication adherence was sub-optimal. The ACQ-5 questions are useful for assessing asthma control, for prompting medication reviews, and for reinforcing benefits of medication compliance to improve long-term asthma control.

    Both asthma and obstructive sleep apnoea cause sleep disturbance, daytime sleepiness and diminished quality of life. Continuous positive airway pressure (CPAP) is efficient in reducing symptoms related to sleep apnoea. Here we report the impact of long-term use of CPAP on asthma symptoms. A survey questionnaire was distributed to all of our obstructive sleep apnoea patients with CPAP therapy in 2013. We used the Finnish version of the Asthma Control Test™ (ACT) and a visual analogue scale (0 = no symptoms, 100 = severe asthma symptoms). Asthma was defined as self-reported physician-diagnosed disease and a special reimbursement for asthma medication by the Social Insurance Institution. We sent 2577 questionnaires and received 1586 answers (61 %). One hundred ninety-seven patients were asthmatics with a prevalence of asthma among CPAP users of 13 %. We studied 152 patients (58 females) whose CPAP therapy was initiated after starting asthma medication. Their mean (SD) age was 62 (10) years, duration of CPAP 5.7 (4.7) years and their CPAP daily use was 6.3 (2.4) h. Self-reported asthma severity decreased significantly from 48.3 (29.6) to 33.1 (27.4) (p CPAP (P CPAP in patients with both asthma and obstructive sleep apnoea.

    Long-term sustainability of health services requires an understanding of patients' values and preferences. The aim of this study was to evaluate patients' preferences as well as their willingness-to-pay (WTP) for a community pharmacy-delivered specialized asthma service using a discrete choice experiment (DCE). Patients with asthma in New South Wales, Australia, who had recently experienced a specialized asthma management service at their pharmacy were mailed DCE questionnaires. Patients were asked to choose between two hypothetical service models with varying attributes. Multinomial logit models estimated patients' marginal WTP. The study had a response rate of 47%. Patients greatly valued various aspects of the pharmacy-based specialized service and had marginal WTP values of AUD$18.00 for a private area, AUD$44.50 for lung function testing, AUD$9.18 for appointments with pharmacists, and AUD$22.80 for provision of comprehensive advice on asthma and its medications. The marginal WTP for the overall service was AUD$94.86. The findings of the study indicate that patients greatly value and are willing to pay for asthma services in pharmacies. The study results will help pharmacists and policy advisors in the development of individualized asthma services that patients will use, are willing to pay for, and thus are economically viable in the future.

    Patient preferences can influence the outcomes of treatment and so understanding and organizing health-care services around these preferences is vital. To explore patient preferences for types of community pharmacy-based asthma services, to investigate the influence of "experience" in molding preferences for such services, and to identify aspects of the services that patients prefer over others. Semistructured face-to-face interviews were conducted with a convenience sample of two types of asthma patients: (1) those naïve to a specialized asthma service and (2) those who had experienced a specialized asthma service. Interviews were audio-recorded, transcribed verbatim, and thematically analyzed. Eighteen interviews were conducted (8 experienced patients, 10 naïve patients). The majority of the patients wanted the pharmacist to play a greater role in their asthma management. Patients experiencing increased levels of service had increased levels of expectations as well as more specific preferences for various aspects of the service. The key aspects of an asthma service that all patients wanted their pharmacists to provide were the provision of information about asthma and its medications, lung function testing and monitoring of their asthma, and checking/correcting their inhaler technique. Patients also expressed a desire for skilled communication and behavioral aspects from the pharmacist such as friendliness, empathy, attentiveness, and dedicated time. Patients highlighted the importance of privacy in the pharmacy. There was a high level of satisfaction toward the currently delivered asthma service among both naïve and experienced patients. The provision of the specialized service was associated with increased patient loyalty to the particular pharmacy. All patients indicated a willingness to participate in future pharmacy-delivered specialized asthma services. Elements of the specialized pharmacy-based asthma services important from a patient's perspective were

Upper abdominal symptoms, suggesting gastroesophageal reflux disease (GERD or functional dyspepsia, occur also in these patients. However, the relationship between these symptoms, concomitant with asthma, and the intensity of eosinophilic airway inflammation remains obscure. Objective: To assess the symptoms of asthma and rhinosinusitis, and to examine the relationship between the symptoms and bronchial inflammation, a new questionnaire, the G scale, was developed. To investigate the effects of GERD, dyspepsia, and rhinosinusitis on asthma symptoms and bronchial inflammation, the symptoms of asthma and rhinosinusitis obtained by the G scale, upper abdominal symptoms obtained by the modified F scale, a questionnaire for GERD and dyspepsia, and fractional exhaled nitric oxide (FeNO were analyzed. Methods: A prospective, observational study was performed in four hospitals in Gunma prefecture, and a retrospective analysis was done using data obtained from five hospitals in Gunma prefecture and Fukui prefecture, Japan. A total of 252 patients diagnosed as having asthma participated in the prospective study. Results: The frequency of daytime phlegm or losing the sense of smell had a positive correlation with FeNO levels in asthmatic

    Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

    To assess any improvements in knowledge of asthma patients after a tailored education program delivered by pharmacists and measure the sustainability of any improvements. To ascertain patients' perceptions about any changes in their knowledge. Ninety-six specially trained pharmacists recruited patients based on their risk of poor asthma control. A tailored intervention was delivered to patients based on individual needs and goals, and was conducted at three or four time points over six months. Asthma knowledge was assessed at the beginning and end of the service, and six and 12 months after it had ended. Patients' perceptions of the impact of the service on their knowledge were explored qualitatively in interviews. The 96 pharmacists recruited 570 patients, 398 (70%) finished. Asthma knowledge significantly improved as a result of the service (7.65 ± 2.36, n=561, to 8.78 ± 2.14, n=393). This improvement was retained for at least 12 months after the service. Patients reported how the knowledge and skills gained had led to a change in the way they managed their asthma. Improvements in knowledge are achievable and sustainable if pharmacists used targeted educational interventions. Pharmacist educational interventions are an efficient way to improve asthma knowledge in the community. Crown Copyright © 2011. Published by Elsevier Ireland Ltd. All rights reserved.

    Asthma exacerbations are frequent in patients with severe disease. This report describes results from two retrospective cohort studies describing exacerbation frequency and risk, emergency department (ED)/hospital re-admissions, and asthma-related costs by asthma severity in the US and UK. Patients with asthma in the US-based Clinformatics™ DataMart Multiplan IMPACT (2010-2011; WEUSKOP7048) and the UK-based Clinical Practice Research Datalink (2009-2011; WEUSKOP7092) databases were categorized by disease severity (Global Initiative for Asthma [GINA]; Step and exacerbation history) during the 12 months pre-asthma medical code (index date). Outcomes included: frequency of exacerbations (asthma-related ED visit, hospitalization, or oral corticosteroid use with an asthma medical code recorded within ±2 weeks) 12 months post-index, asthma-related ED visits/hospitalization, and asthma-related costs 30 days post-index. Risk of a subsequent exacerbation was determined by proportional hazard model. Of the 222,817 and 211,807 patients with asthma included from the US and UK databases, respectively, 12.5 and 8.4% experienced ≥1 exacerbation during the follow-up period. Exacerbation frequency increased with disease severity. Among the 5,167 and 2,904 patients with an asthma-related ED visit/hospitalization in the US and UK databases, respectively, 9.2 and 4.7% had asthma-related re-admissions within 30 days. Asthma-related re-admission rates and costs increased with disease severity, approximately doubling between GINA Step 1 and 5 and in patients with ≥2 versus <2 exacerbations in the previous year. Risk of a subsequent exacerbation increased 32-35% for an exacerbation requiring ED visit/hospitalization versus oral corticosteroids. Increased disease severity was associated with higher exacerbation frequency, ED/hospitalization re-admission, costs and risk of subsequent exacerbation, indicating that these patients require high-intensity post-exacerbation management.

    Full Text Available OBJECTIVE: To identify risk factors for death among patients with severe asthma. METHODS: This was a nested case-control study. Among the patients with severe asthma treated between December of 2002 and December of 2010 at the Central Referral Outpatient Clinic of the Bahia State Asthma Control Program, in the city of Salvador, Brazil, we selected all those who died, as well as selecting other patients with severe asthma to be used as controls (at a ratio of 1:4. Data were collected from the medical charts of the patients, home visit reports, and death certificates. RESULTS: We selected 58 cases of deaths and 232 control cases. Most of the deaths were attributed to respiratory causes and occurred within a health care facility. Advanced age, unemployment, rhinitis, symptoms of gastroesophageal reflux disease, long-standing asthma, and persistent airflow obstruction were common features in both groups. Multivariate analysis showed that male gender, FEV1 pre-bronchodilator < 60% of predicted, and the lack of control of asthma symptoms were significantly and independently associated with mortality in this sample of patients with severe asthma. CONCLUSIONS: In this cohort of outpatients with severe asthma, the deaths occurred predominantly due to respiratory causes and within a health care facility. Lack of asthma control and male gender were risk factors for mortality.

    Asthma treatment guidelines recommend medications based on the level of asthma control. To evaluate differences in asthma control between patients who initiated asthma controller monotherapy versus combination therapy. Children (5-16 years; n = 488) and adults (17-80 years; n = 530) with asthma and no controller therapy in the prior 6 months were included. Telephone surveys were conducted within 5 days of filling a new asthma controller prescription with either the caregiver of children or the adult patient. Demographics, asthma control before therapy, and asthma-related resource use were assessed for patients initiating monotherapy (filling one asthma controller prescription) and combination therapy (filling more than one controller medication or a fixed-dose combination). Mean pediatric age was 10 years; 53% were male. Mean adult age was 47 years; 25% were male. There were no significant differences in asthma control score between patients receiving monotherapy and combination therapy. Children on combination therapy did not have more nighttime awakening or short-acting β-agonist use but were more likely to have been hospitalized due to asthma attack (p = .05) and have more unscheduled (p = .0374) and scheduled (p = .009) physician visits. Adults on combination therapy were more likely to have been hospitalized due to asthma attack (p asthma (p asthma control scores in the 4 weeks before index medication suggests that asthma severity during a treatment-free period did not differ significantly for patients initiating controller monotherapy versus combination therapy. From these findings, it appears that although physicians may not focus on asthma control when choosing the intensity of initial controller therapy, the intensity of health-care encounters may be an influence.

    This study was planned to evaluate vocal cord functions and to establish underlying vocal cord dysfunctions (VCD) in patients with asthma attack. All patients admitted to emergency service of our hospital with asthma attack between February 01, 2007 and June 01, 2007 were included in the evaluation. After the evaluation, all patients regarded to have asthma attacks based on GINA 2006 guide were enrolled in the study. After first intervention, patients underwent endoscopic larynx examination for the evaluation of vocal cord functions. Twenty four (65.7%) male and 11 female (31.4%), overall 35 patients diagnosed with asthma and who did not have the history of another disease were included in the study. At endoscopic larynx examination carried out after first medical examination, at the moment of asthma attack, tongue, tongue base, epiglottis and arytenoid were observed to be within normal limits. In 9 (25.7%) patients, upper respiratory tract was hyperemic and in 2 (5.7%) odematous. One patient had nasal polyposis (p> 0.05). In the evaluation of vocal cord functions, restriction in adduction was observed in merely one patient. All other functions were normal. Rima opening width was established to be mean 8.34 + or - 0.725. VCD was deteced in none of the patients included in the study. Although we did not detect VCD in any patient, VCD should be borne in mind in cases which presents with the clinical picture of asthma and responds weakly to the treatment or in cases of unexplained shortness of breath. This may prevent many unnecessary procedures such as medication, entubation, tracheostomy and iatrogenic mortality. Further longutudial studies are required in order to shed light on the assocation of asthma with VCD.

    Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

    We prospectively recruited patients admitted to the hospital with severe asthma to comprehensively evaluate the association of historical and physiologic features with the risk of near-fatal asthma (NFA). A case-control study design was used. All patients admitted with NFA (cases) were identified prospectively and compared with asthma patients admitted during the same period without respiratory failure (controls). Nineteen cases (age: 40.2 +/- 12.0 yr) (mean +/- SD) and 80 controls (age: 36 +/- 13.5 yr) were enrolled. Duration of asthma, gender, smoking status, ethnicity, and prevalence of atopy were similar in the case and control groups. More than 80% of patients in both groups reported worsening symptoms for more than 48 h before admission, and more than 50% were worse for longer than 7 d. There was no difference in degree of airways obstruction or bronchial hyperresponsiveness (PC20). Perception of dyspnea was similar in the cases and controls, but among cases the males had greater impairment than the females (Borg score: 1.9 +/- 1. 4 versus 3.9 +/- 1.2: p = 0.05). Univariate analysis identified a history of previous mechanical ventilation (OR: 27.5; 95% CI: 6.60 to 113.7), admission to the intensive care unit (ICU) (OR: 9.9; 95% CI: 3.0 to 32.9), history of worse asthma during January and February (OR: 3.5; 95% CI: 1.0 to 11.8), and use of air-conditioning (OR: 15.0; 95% CI: 1.3 to 166) as risk factors for NFA. Of concern was the dependence of most patients (59.8%) on the emergency department (ED) for initial care, and the small number of cases (16%) in which patients visited a physician before admission to the hospital. We have confirmed risk factors identified previously in retrospective studies of fatal and NFA, and have also shown that hospitalized patients with asthma, irrespective of severity of their asthma, share several characteristics, especially in terms of their failure to respond to worsening asthma.

    Asthma is a common chronic condition. Work-related asthma (WRA) has a large socioeconomic impact and is increasing in prevalence but remains under-recognized. Although international guidelines recommend patient education, no widely available educational tool exists. To develop a WRA educational website for adults with asthma. An evidence-based database for website content was developed, which applied evidence-based website design principles to create a website prototype. This was subsequently tested and serially revised according to patient feedback in three moderated phases (one focus group and two interview phases), followed by face validation by asthma educators. Patients (n=10) were 20 to 28 years of age; seven (70%) were female, three (30%) were in university, two (20%) were in college and five (50%) were currently employed. Key format preferences included: well-spaced, bulleted text; movies (as opposed to animations); photos (as opposed to cartoons); an explicit listing of website aims on the home page; and an exploding tab structure. Participants disliked integrated games and knowledge quizzes. Desired informational content included a list of triggers, prevention⁄control methods, currently available tools and resources, a self-test for WRA, real-life scenario presentations, compensation information, information for colleagues on how to react during an asthma attack and a WRA discussion forum. The website met the perceived needs of young asthmatic patients. This resource could be disseminated widely and should be tested for its effects on patient behaviour, including job choice, workplace irritant⁄allergen avoidance and⁄or protective equipment, asthma medication use and physician prompting for management of WRA symptoms.

    In January 2013, extremely high concentrations of fine particles (PM2.5) were observed around Beijing, China. In Japan, the health effects of transboundary air pollution have been a matter of concern. We examined the association between the levels of outdoor PM2.5 and other air pollutants with primary care visits (PCVs) at night due to asthma attack in Himeji City, western Japan. A case-crossover study was conducted in a primary care clinic in Himeji City, Japan, involving 112 subjects aged 0-80 years who visited the clinic due to an asthma attack between 9 p.m. and 6 a.m. during the period January-March, 2013. Daily concentrations of particulate matter, ozone, nitrogen dioxide, and some meteorological elements were measured, and a conditional logistic regression model was used to estimate the odds ratios (OR) of PCVs per unit increment in air pollutants or meteorological elements. Of the 112 subjects, 76 (68 %) were aged asthma attack at night. A positive relation between ozone and PCVs due to asthma attack was detected. The OR per 10 ppb increment in daily mean ozone the day before the visit was 2.31 (95 % confidence interval 1.16-4.61). These findings do not support an association between daily mean concentration of PM2.5 and PCVs at night. However, we did find evidence suggesting that ozone is associated with PCVs.

    The "credit card" asthma self-management plan provides the adult asthmatic patient with simple guidelines for the self-management of asthma, which are based on the self-assessment of peak expiratory flow rate recordings and symptoms. The study was a trial of the clinical efficacy of the credit card plan in a high-risk group of asthmatic patients. In this "before-and-after" trial, patients discharged from the emergency department of Wellington Hospital, after treatment for severe asthma were invited to attend a series of hospital outpatient clinics at which the credit card plan was introduced. Questionnaires were used to compare markers of asthma morbidity, requirement for emergency medical care, and medication use during the 6-month period before and after intervention with the credit card plan. Of the 30 patients with asthma who attended the first outpatient clinic, 26 (17 women and 9 men) completed the program. In these 26 participants, there was a reduction in both morbidity and requirement for acute medical services: specifically, the proportion waking with asthma more than once a week decreased from 65% to 23% (p = 0.005) and the proportion visiting the emergency department for treatment of severe asthma decreased from 58% to 15% (p = 0.004). The patients attending the clinics commented favorably on the plan, in particular on its usefulness as an educational tool for monitoring and treating their asthma. Although the interpretation of this study is limited by the lack of a randomized control group, the findings are consistent with other evidence that the credit card asthma self-management plan can be an effective and acceptable system for improving asthma care in a high-risk group of adult patients with asthma.

    Background Asian dust (AD) exposure exacerbates pulmonary dysfunction in patients with asthma. Asthma–chronic obstructive pulmonary disease overlap syndrome (ACOS), characterized by coexisting symptoms of asthma and chronic obstructive pulmonary disease, is considered a separate disease entity. Previously, we investigated the effects of AD on pulmonary function in adult patients with asthma. Here, we present the findings of our further research on the differences in the effects of AD exposure on pulmonary function between patients with asthma alone and those with ACOS. Methods Between March and May 2012, we conducted a panel study wherein we monitored daily peak expiratory flow (PEF) values in 231 adult patients with asthma. These patients were divided into 190 patients with asthma alone and 41 patients with ACOS in this study. Daily AD particle levels were measured using light detection and ranging systems. Two heavy AD days (April 23 and 24) were determined according to the Japan Meteorological Agency definition. A linear mixed model was used to estimate the association between PEF and AD exposure. Results Increments in the interquartile range of AD particles (0.018 km−1) led to PEF changes of −0.50 L/min (95% confidence interval, −0.98 to −0.02) in patients with asthma alone and −0.11 L/min (−0.11 to 0.85) in patients with ACOS. The PEF changes after exposure to heavy AD were −2.21 L/min (−4.28 to −0.15) in patients with asthma alone and −2.76 L/min (−6.86 to 1.35) in patients with ACOS. In patients with asthma alone, the highest decrease in PEF values was observed on the heavy AD day, with a subsequent gradual increase over time. Conclusion Our results suggest that the effects of AD exposure on pulmonary function differ between patients with asthma alone and ACOS, with the former exhibiting a greater likelihood of decreased pulmonary function after AD exposure.

    Inhaled anticholinergics such as ipratropium bromide (IB), when administered with β2-agonists, are effective in reducing hospital admissions of children presenting to the emergency department with moderate to severe asthma. However, treatment of acute asthma with IB is still uncommon in Japan. The aim of this study was to investigate the effectiveness and safety of IB for the treatment of pediatric acute asthma. We conducted a retrospective study to compare the admission rate of patients who received IB with those who did not. Patients aged 4 years or older with a history of moderate to severe attacks were included. For analysis, propensity score matching was used to adjust the confounding factors related to IB use. Patients received IB by metered-dose inhaler (40μg per dose) with a spacer three times at 20-min intervals. Among 175 patients included in the analysis, 102 patients were treated with IB (IB group) and 73 patients were treated without IB (Non-IB group). A propensity score matching analysis extracted 63 patients from each group. There was no statistical difference between the two groups in terms of admission rate (IB group 12.7% vs Non-IB group 9.5%; p=0.78). One patient (1.0%) treated with IB experienced dryness of the mouth, which resolved spontaneously. The admission rate did not decline with IB use. Several confounding factors could have influenced and limited our results. A prospective study is needed to investigate the effectiveness of IB in Japan.

    Background: Asthma is one of the most common chronic diseases in the world, and previous studies have reported low levels of control. Recent developments in the availability and use of online sources of information about asthma might add to patients’ knowledge and help improve control. Aims: To investigate whether asthma control has improved by assessing levels of symptoms, exacerbations and Global Initiative for Asthma-defined control in a real-life population of patients who use the Internet and social media, as well as evaluate patient perception of control and attitudes to asthma. Methods: Online surveys were conducted among 8,000 patients with asthma (aged 18–50 years, ⩾2 prescriptions in the previous 2 years, use of social media) from 11 European countries. Results: Levels of asthma control were low: 45% of respondents had uncontrolled asthma. Acute exacerbations were common: 44% of respondents reported having used oral steroids for asthma in the previous 12 months, 24% had visited an emergency department and 12% had been hospitalised. More than 80% of respondents (overall, and among those with a history of exacerbations) considered their asthma to be controlled. Of those who had an exacerbation requiring oral steroids, 75% regarded their asthma as not serious. Conclusions: Asthma control in Europe remains poor; symptoms and exacerbations are common. Many patients regard their asthma as controlled and not serious despite experiencing symptoms and exacerbations. There is a need to assess patients’ control, risk and inhaler technique, and to ensure that patients are prescribed, and take, appropriate treatments. PMID:24921985

    Full Text Available Abstract Background Clinical trials show that asthma can be controlled in the majority of patients, but poorly controlled asthma still imposes a considerable burden. The level of asthma control achieved reflects the behaviour of both healthcare professionals and patients. A key challenge for healthcare professionals is to help patients to engage in self-management behaviours with optimal adherence to appropriate treatment. These issues are particularly relevant in primary care, where most asthma is managed. An international panel of experts invited by the International Primary Care Respiratory Group considered the evidence and discussed the implications for primary care practice. Discussion Causes of poor control Clinical factors such as exposure to triggers and concomitant rhinitis are important but so are patient behavioural factors. Behaviours such as smoking and nonadherence may reduce the efficacy of treatment and patients' perceptions influence these behaviours. Perceptual barriers to adherence include doubting the need for treatment when symptoms are absent and concerns about potential adverse effects. Under-treatment may also be related to patients' underestimation of the significance of symptoms, and lack of awareness of achievable control. Implications Three key implications for healthcare professionals emerged from the debate. First, the need for simple tools to assess asthma control. Two approaches considered were the monitoring of biometric markers of control and questionnaires to record patient-reported outcomes. Second, to understand the reasons for poor control for individual patients, identifying both clinical (e.g. rhinitis and behavioural factors (e.g. smoking and nonadherence to treatment. Third was the need to incorporate, within asthma review, an assessment of patient perspectives including their goals and aspirations and to elicit their beliefs and concerns about asthma and its treatment. This can be used as a basis for

    OBJECTIVE Although asthma is often inappropriately treated in children, little is known about what information pediatricians use to adjust asthma therapy. The purpose of this work was to assess the importance of various dimensions of patient asthma status as the basis of pediatrician treatment decisions. PATIENTS AND METHODS We conducted a cross-sectional, random-sample survey, between November 2005 and May 2006, of 500 members of the American Academy of Pediatrics using standardized case vignettes. Vignettes varied in regard to (1) acute health care use (hospitalized 6 months ago), (2) bother (parent bothered by the child’s asthma status), (3) control (frequency of symptoms and albuterol use), (4) direction (qualitative change in symptoms), and (5) wheezing during physical examination. Our primary outcome was the proportion of pediatricians who would adjust treatment in the presence or absence of these 5 factors. RESULTS Physicians used multiple dimensions of asthma status other than symptoms to determine treatment. Pediatricians were significantly more likely to increase treatment for a recently hospitalized patient (45% vs 18%), a bothered parent (67% vs 18%), poorly controlled symptoms (4–5 times per week; 100% vs 18%), or if there was wheezing on examination (45% vs 18%) compared with patients who only had well-controlled symptoms. Pediatricians were significantly less likely to decrease treatment for a child with well-controlled symptoms and recent hospitalization (28%), parents who reported being bothered (43%), or a child whose symptoms had worsened since the last doctor visit (10%) compared with children with well-controlled symptoms alone. CONCLUSIONS Pediatricians treat asthma on the basis of multiple dimensions of asthma status, including hospitalization, bother, symptom frequency, direction, and wheezing but use these factors differently to increase and decrease treatment. Tools that systematically assess multiple dimensions of asthma may be useful

    If novel health services are to be implemented and sustained in practice, the perceptions and views of patients form a critical part of their evaluation. The aims of this study were to explore patient's perceptions and experiences with a pharmacy asthma service and to investigate if there was a change over time. Interviews and focus groups were conducted with patients participating in the asthma service at three time points. Data were transcribed verbatim and thematically analyzed using a framework approach. The service led to an enhanced awareness and understanding of asthma, changes in participants' beliefs and attitudes towards asthma management, changes in asthma-related health behaviours and improved self-efficacy. Participants were very positive about the service and the role of the pharmacist in asthma management. There was a shift in participant perceptions and views, from being at an abstract level in those who had completed just one visit of the service to a more experiential level in those who had experienced the entire comprehensive asthma service. A sustained experience/multiple visits in a service may lead to more concrete changes in patient perceptions of severity, beliefs, health behaviours and enhanced self-efficacy and control. The study highlights a need for such asthma services in the community. © 2014 Royal Pharmaceutical Society.

    As an art form, drawings can facilitate the tangible expression of patients' inner images and feelings in a range of health conditions. However, there are currently no published studies investigating adults' perspectives of asthma using drawings. This study aimed to explore how adults' drawings illustrate their perceptions and experiences of asthma. Adults with asthma participated in a one-on-one drawing activity. Analysis was grounded in the participants' accounts of their drawing, which were examined alongside the relevant image. A coding approach was used to cluster thematic material and map the data according to the Common-Sense Model of Self-Regulation (CSM). Eighteen participants took part. Three themes emerged: (1) asthma is constrictive and restrictive, (2) feeling alone, feeling different, and (3) the life journey of asthma. The drawings aligned with several domains of the CSM, in particular consequences. The images drawn by the participants and their subsequent discussions highlighted the prominence of the emotional burden of asthma. The drawings provided powerful and evocative communication of the experience of asthma. Future research using drawings can further both healthcare professionals' and patients' understanding of the physical, social and emotional demands of living with asthma, and support the development of asthma self-management practices.

    To analyze the distinctive pathological characteristics in the spectrums of spontaneous infrared radiation at the Taiyuan (LU 9) acupoint in patients with asthma. A highly sensitive infrared spectrum detecting device was used to detect the spectrums of spontaneous infrared radiation at Taiyuan (LU 9) in 37 asthma patients and 34 healthy volunteers. Asthma patients had significantly lower infrared intensity than that of the healthy volunteers (P>0.01). Asthma patients had significantly lower overall infrared radiation intensity at the left Taiyuan (LU 9) than that of healthy volunteers (P > 0.05), but there was no significant difference between healthy volunteers and asthma patients at the right Taiyuan (LU 9) (P > 0.05). The infrared radiation intensity of 17 wavelength spots at the left Taiyuan (LU 9) and 4 wavelength spots at the right Taiyuan (LU 9) in asthma patients were significantly lower than those of healthy volunteers (P > 0.05). At 2 microm, the infrared radiation intensity of asthma patients was significantly stronger than that of healthy volunteers (P > 0.05). At 19 wavelength spots in the healthy volunteers and at 4 wave-length spots in the asthma patients, the left Taiyuan (LU 9) showed a significantly stronger intensity than that of the right Taiyuan (LU 9) (P > 0.05S). By Pearson's chi2 test, healthy volunteers had more wavelength spots that were significantly different between the left and right Taiyuan (LU 9) than the asthma patients (P > 0.01). Changes in the infrared spectrum at the Taiyuan (LU 9) acupoint in asthma patients may reflect distinct pathological changes. Certain acupuncture points may be related to specific organs.

    Few studies to date have investigated the antioxidant nutrients such as vitamin C (ascorbic acid), vitamin E (α-tocopherol), retinol and carotenoids in plasma from patients with pulmonary disease in Japan. To clarify the role of antioxidant nutrients such as vitamin C, vitamin E, retinol and various carotenoids in plasma of Japanese patients with chronic obstructive lung diseases (COPD), asthma-COPD overlap syndrome (ACOS) and/or bronchial asthma (BA), we compared to healthy elderly controls. Ascorbic acid (AA), carotenoids (lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene and lycopene), retinol and α-tocopherol levels in plasma were determined by using a high performance liquid chromatography. Reduced glutathione (GSH), oxidised glutathione (GSSG) in whole blood and urinary 8-OHdG were also determined. Plasma AA level of COPD subjects was significantly lower than that of healthy elderly people. Conversely, ACOS and BA subjects showed no significant difference from healthy elderly people. Moreover, plasma lycopene and total carotenoid levels and GSH content in blood were significantly lower in COPD subjects than these in healthy elderly people. However, other redox markers such as GSSG, GSH/GSSG ratio and urinary 8-OHdG found no significant differences between COPD, ACOS and BA compared to healthy elderly people. These results suggested that COPD of Japanese patients may develop partly because of oxidative stress derived from a shortage of antioxidant nutrients, especially of AA and lycopene, as well as GSH while this may not be the case in both ACOS and BA. © 2016 John Wiley & Sons Ltd.

    Previous cluster analyses on asthma are based on cross-sectional data. To identify phenotypes of adult-onset asthma by using data from baseline (diagnostic) and 12-year follow-up visits. The Seinäjoki Adult Asthma Study is a 12-year follow-up study of patients with new-onset adult asthma. K-means cluster analysis was performed by using variables from baseline and follow-up visits on 171 patients to identify phenotypes. Five clusters were identified. Patients in cluster 1 (n = 38) were predominantly nonatopic males with moderate smoking history at baseline. At follow-up, 40% of these patients had developed persistent obstruction but the number of patients with uncontrolled asthma (5%) and rhinitis (10%) was the lowest. Cluster 2 (n = 19) was characterized by older men with heavy smoking history, poor lung function, and persistent obstruction at baseline. At follow-up, these patients were mostly uncontrolled (84%) despite daily use of inhaled corticosteroid (ICS) with add-on therapy. Cluster 3 (n = 50) consisted mostly of nonsmoking females with good lung function at diagnosis/follow-up and well-controlled/partially controlled asthma at follow-up. Cluster 4 (n = 25) had obese and symptomatic patients at baseline/follow-up. At follow-up, these patients had several comorbidities (40% psychiatric disease) and were treated daily with ICS and add-on therapy. Patients in cluster 5 (n = 39) were mostly atopic and had the earliest onset of asthma, the highest blood eosinophils, and FEV 1 reversibility at diagnosis. At follow-up, these patients used the lowest ICS dose but 56% were well controlled. Results can be used to predict outcomes of patients with adult-onset asthma and to aid in development of personalized therapy (NCT02733016 at ClinicalTrials.gov). Copyright © 2017 The Authors.

    Objective: To investigate warning symptoms of asthma attack and evaluate asthma self-management status of asthma patients in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out from 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of frequency and warning symptoms of asthma attack, the time from warning symptoms to asthma attack, the impact of asthma attack and asthma self-management were collected from asthma patients of outpatient department. Results: Altogether 3 875 asthmatic outpatients were recruited. 78.1% (3 026/3 875) of the patients reported restriction of exercise and daily activities during asthma exacerbation. 82.5% (3 160/3 829) of the patients had warning symptoms before asthma attack, the most common warning symptoms were cough, chest tightness and shortness of breath. The median time from warning symptoms to asthma attack was 2 h, the mean time was 90 h. Only 4.4% (167/3 829) of the patients had definite confidence to control asthma when symptoms deteriorated. 76.7% (2 937/3 828) of the patients used medications to control asthma when asthma symptoms deteriorated. Medication choice: inhaled corticosteroid (ICS) + formoterol 45.8% (1 776/3 875), short-acting beta-agonist (SABA) 23.9% (927/3 875). Conclusions: Most asthma patients have warning symptoms before asthma attack, the most common symptoms are cough, chest tightness and shortness of breath. The proportion of patients conducting effective asthma self-management remains low.

    Bronchial asthma is characterized by chronic airway inflammation. The primary goal of treatment of asthma is to maintain the state of control. According to the Japanese guidelines (JGL2012), long-term management consists of 4 therapeutic steps, and use of inhaled corticosteroids (ICS) is recommended at all 4 steps. Besides ICS, inhalation of long-acting β2-agonist (LABA) is also effective. Recently, omalizumab (a humanized antihuman IgE antibody) can be available for patients with severe allergic asthma. Although there is no specific strategy for preoperative treatment of patients with asthma, preoperative systemic steroid administration seemed to be effective to prevent asthma attack during anesthesia. The most common cause of chronic bronchitis is smoking. Even the respiratory function is within normal limits, perioperative management of patients with chronic bronchitis is often troublesome. The most common problem is their sputum. To minimize perioperative pulmonary complication in these patients, smoking cessation and pulmonary rehabilitation are essential. It is known that more than 1 month of smoking cessation is required to reduce perioperative respiratory complication. However, even one or two weeks of smoking cessation can decrease sputum secretion. In summary, preoperative optimization is most important to prevent respiratory complication in patients with bronchial asthma or chronic bronchitis.

    Full Text Available Introduction: The family and psychological approaches in asthma patients are essential because a dysfunctional family can increase asthma symptoms of the sick child. Aim: To determine family functioning and classification of asthma in pediatric patients, and the condition in the areas that comprises it. Method: A cross-sectional study in asthmatic patients treated in pediatrics Regional General Hospital No. 1 between April and July 2015 was done. Asthma severity was classified in response to the GINA 2010 guide. The Dr. Emma Espejel Scale of Family Functioning was applied to the patient's family. Results: The male presented more severe asthma by 70%, especially in school age. The dysfunction of the control area of family dynamics in the Mexican family impact on the severity of asthma. Discussion and Conclusion: 50% of families with a carrier member of asthma reflect dysfunction; control area was the most affected. Family and psychological approaches in patients with asthma are basic to prevent changes in family function.

    Specialized community pharmacy services, involving the provision of disease state management and care by pharmacists, have been developed and trialled and have demonstrated very good health outcomes. Most of these services have been developed from a healthcare professional perspective. However, for the future uptake and long-term sustainability of these services as well as for better and sustained health outcomes for patients, it is vital to gain an understanding of patients' preferences. We can then structure healthcare services to match these preferences and needs rather than around clinical viewpoints alone. The aim of this study was to elicit patient preferences for pharmacy-based specialized asthma services using a discrete choice experiment and to explore the value/importance that patients place on the different attributes of the asthma service. The existence of preference heterogeneity in the population was also investigated. The study was conducted with asthma patients who had recently experienced a specialized asthma management service at their pharmacy in New South Wales, Australia. Pharmacists delivering the asthma service mailed out the discrete choice questionnaires to participating patients at the end of 6 months of service provision. A latent class (LC) model was used to investigate each patient's strength of preference and preference heterogeneity for several key attributes related to asthma service provision: frequency of visits, access to pharmacist, interaction with pharmacy staff, availability of a private area for consultation, provision of lung function testing, type and depth of advice provision, number of days with asthma symptoms and cost of service. Eighty useable questionnaires (of 170 questionnaires sent out) were received (response rate 47.1%). The study identified various key elements of asthma services important to patients. Further, the LC analysis revealed three classes with differing patient preferences for levels of asthma service

    The hypothesis that GER can trigger or exacerbate asthma is supported by several clinical trials that have shown amelioration in asthma symptoms and/or an improvement in pulmonary function after antireflux therapy. To investigate the prevalence of GER in patients with difficult to control asthma and to determine the effect of omeprazole on asthma symptoms, reflux symptoms, pulmonary function and on the requirement of asthma medications. Patients with difficult to control asthma were recruited into the study. All patients underwent esophageal manometry and 24 hour esophageal pH monitoring. Pulmonary function tests were done before and after treatment. The severity of asthma and reflux was assessed by a 1 week pulmonary symptom score(PSS) and reflux symptom score(RSS) respectively before and after treatment. Those who had an abnormal pH study (pH 5% of the time) underwent anti-GER treatment with lifestyle changes, and a proton pump inhibitor (omeprazole 40 mg, bid) for 3 months. Asthma medications were added or deleted based on severity of asthma. Out of 250 asthmatic patients screened, forty patients fulfilled the inclusion criteria. Twenty eight of 40 patients(70%) were diagnosed to have GERD. Of the patients 28 with GER, 8 patients(28.5%) had no reflux symptoms. On 24 hr pH metry, the percentage time pH reflux symptom score(RSS) improved from 22.39 ± 14.99 to 1.04 ± 1.07, pulmonary symptom score(PSS) improved from 27.14 ± 7.49 to 13.82 ± 4.21 and night time asthma symptom score(NASS) improved from 6.71 ± 1.80 to 3.04 ± 1.23 (p-value <0.0001). After treatment, FEV1 and PEFR increased from 1.38 ± 0.57 and 4.14 ± 1.97 to 1.47 ± 0.54 and 5.56 ± 1.72, respectively (p-value 0.00114). PPI therapy improves nocturnal asthma symptoms, daytime asthma symptoms, pulmonary function and decreases requirement of asthma medications in these patients.

    Denial of having a chronic condition, poor knowledge of the disease process and lack of adherence to standard treatment are often considered to be important factors that increase morbidity in asthma. We evaluated the effect of standard treatment guidelines and asthma education programme on asthma control among patients enrolled from a referral health facility of Delhi in India. Fifty patients who visited the health facility first time for treatment of asthma were enrolled after confirming the diagnosis of asthma by symptoms and reversible spirometry. Patients were interviewed at baseline using three researcher-administered questionnaires - quality of asthma management questionnaire, asthma control questionnaire (ACQ) and asthma knowledge questionnaire (AKQ). All patients were given pharmacotherapy according to standard treatment guidelines. In addition, every alternate patient was also given a face-to-face educational intervention. Patients were followed up at 2, 4, 8 and 12 weeks. The ACQ was used at each visit, and AKQ was reassessed at the twelfth week. The paired t test was used to detect significant changes in various domains of asthma control. The knowledge of asthma among patients and the care provided by previous health-care providers were found to be poor at baseline assessment. The application of standard treatment guidelines improved asthma control by the second week and the changes became significant by the fourth week, which persisted till the twelfth week (p Standard treatment guidelines and asthma education improved asthma control.

    Conclusion: Vitamin D deficiency was highly prevalent in COPD and bronchial asthma (100% and 50% respectively. Low levels of vitamin D were associated with low FEV1%, frequent exacerbations in patients with COPD and bronchial asthma, and increased COPD severity as assessed by GOLD guidelines. Important statistically significant negative associations between vitamin D level and both asthma control and asthma severity according to GINA classification were also found. Thus it is advised to include vitamin D levels in the routine assessment of patients with bronchial asthma and COPD, as well as studying the importance and clinical impact of oral supplementation of vitamin D in patients with COPD and bronchial asthma should be an important goal of future research.

    Asthma is heterogeneous, and airway dysbiosis is associated with clinical features in patients with mild-to-moderate asthma. Whether similar relationships exist among patients with severe asthma is unknown. We sought to evaluate relationships between the bronchial microbiome and features of severe asthma. Bronchial brushings from 40 participants in the Bronchoscopic Exploratory Research Study of Biomarkers in Corticosteroid-refractory Asthma (BOBCAT) study were evaluated by using 16S ribosomal RNA-based methods. Relationships to clinical and inflammatory features were analyzed among microbiome-profiled subjects. Secondarily, bacterial compositional profiles were compared between patients with severe asthma and previously studied healthy control subjects (n = 7) and patients with mild-to-moderate asthma (n = 41). In patients with severe asthma, bronchial bacterial composition was associated with several disease-related features, including body mass index (P PERMANOVA), changes in Asthma Control Questionnaire (ACQ) scores (P < .01), sputum total leukocyte values (P = .06), and bronchial biopsy eosinophil values (per square millimeter, P = .07). Bacterial communities associated with worsening ACQ scores and sputum total leukocyte values (predominantly Proteobacteria) differed markedly from those associated with body mass index (Bacteroidetes/Firmicutes). In contrast, improving/stable ACQ scores and bronchial epithelial gene expression of FK506 binding protein (FKBP5), an indicator of steroid responsiveness, correlated with Actinobacteria. Mostly negative correlations were observed between biopsy eosinophil values and Proteobacteria. No taxa were associated with a TH2-related epithelial gene expression signature, but expression of TH17-related genes was associated with Proteobacteria. Patients with severe asthma compared with healthy control subjects or patients with mild-to-moderate asthma were significantly enriched in Actinobacteria, although the largest differences

    Exposure to indoor allergens is an established risk factor for poor asthma control. Current guidelines recommend removing pets from the home of patients with asthma. This cross-sectional study was conducted to determine the prevalence of furry pet ownership in asthmatics compared to non-asthmatics and to identify factors associated with furry pet ownership among those with asthma. Secondary analysis assessed characteristics among asthmatics that might be associated with allowing a furry pet into the bedroom. Using data from The National Asthma Survey collected from 2003 to 2004, we carried out univariate and multiple regression analyses, in 2009, to identify independent predictors of furry pet ownership in asthma sufferers after controlling for potential confounders. Overall, asthmatics were more likely to own a furry pet than nonasthmatic individuals in the general population (49.9% versus 44.8%, p ownership among asthmatics. Additionally, 68.7% of patients with asthma who own a furry pet allowed them into their bedroom. Higher income and carrying out ownership is equally or more common among asthmatics compared to those without asthma. The majority of asthmatics with furry pets allow them into the bedroom. Recognizing and addressing these problems may help decrease asthma morbidity.

    Full Text Available Abstract Background This study examined the attitudes and actions of 3415 physician-recruited adults aged ≥ 16 years with asthma in eleven countries who were prescribed regular maintenance therapy with inhaled corticosteroids or inhaled corticosteroids plus long-acting β2-agonists. Methods Structured interviews were conducted to assess medication use, asthma control, and patients' ability to recognise and self-manage worsening asthma. Results Despite being prescribed regular maintenance therapy, 74% of patients used short-acting β2-agonists daily and 51% were classified by the Asthma Control Questionnaire as having uncontrolled asthma. Even patients with well-controlled asthma reported an average of 6 worsenings/year. The mean period from the onset to the peak symptoms of a worsening was 5.1 days. Although most patients recognised the early signs of worsenings, the most common response was to increase short-acting β2-agonist use; inhaled corticosteroids were increased to a lesser extent at the peak of a worsening. Conclusion Previous studies of this nature have also reported considerable patient morbidity, but in those studies approximately three-quarters of patients were not receiving regular maintenance therapy and not all had a physician-confirmed diagnosis of asthma. This study shows that patients with asthma receiving regular maintenance therapy still have high levels of inadequately controlled asthma. The study also shows that patients recognise deteriorating asthma control and adjust their medication during episodes of worsening. However, they often adjust treatment in an inappropriate manner, which represents a window of missed opportunity.

    Asthma is a disease where there is an accumulation of collagen in the reticular basal membrane of the airway leading to chronic inflammation. The enzyme prolidase plays an important role in the breakdown of collagen and the breakdown of intracellular protein especially in the final stage when peptides and dipeptides contain a high level of proline. To evaluate the relationship between prolidase activity and oxidative status in asthma patients. Comparison was made between 42 patients diagnosed with bronchial asthma and 32 healthy children of similar age and gender. Serum prolidase activity was measured spectrophotometrically. Oxidative status was determined using total antioxidant capacity (TAC) and total oxidant status (TOS) measurement. The prolidase activity of the asthma patient group was statistically significant compared with the control group (P< or =0.001). TAC and TOS levels in the asthma patient group were higher than the control group (P< or =0.001, P< or =0.002, respectively). No correlation was found between the prolidase and oxidative levels of the two groups. A positive correlation was determined between the prolidase activity and TAC in the asthma patient group (P< or =0.001, r=0.501). The prolidase enzyme activity, which plays a role in the collagen turnover, was low in the asthma patients; therefore, their collagen metabolism had undergone a change and this indicates that there may be an effect on the accumulation of collagen in the reticular basal membrane. Moreover, the high level of TOS indicates that these patients were exposed to severe oxidative stress with an increased TAC response. (c) 2009 Wiley-Liss, Inc.

    Patients included in clinical trials do not necessarily reflect the real-world population. To understand the characteristics, including disease and comorbidity burden, of patients with asthma receiving omalizumab in a real-world setting. The Prospective Observational Study to Evaluate Predictors of Clinical Effectiveness in Response to Omalizumab (PROSPERO) was a US-based, multicenter, single-arm, and prospective study. Patients (≥12 years of age) with allergic asthma initiating omalizumab treatment based on physician-assessed need were included and followed for 12 months. Exacerbations, health care use, adverse events, and Asthma Control Test (ACT) scores were assessed monthly. Biomarkers (blood eosinophils, fractional exhaled nitric oxide, and periostin) were evaluated and patient-reported outcomes (Asthma Quality of Life Questionnaire for 12 Years and Older [AQLQ+12] and Work Productivity and Activity Impairment: Asthma questionnaire [WPAI:Asthma]) were completed at baseline and months 6 and 12. The Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) was completed at baseline and 12 months. Most of the 806 enrollees (91.4%) were adults (mean age 47.3 years, SD 17.4), white (70.3%), and female (63.5%). Allergic comorbidity was frequently reported (84.2%), as were hypertension (35.5%) and depression (22.1%). In the 12 months before study entry, 22.1% of patients reported at least 1 asthma-related hospitalization, 60.7% reported at least 2 exacerbations, and 83.3% reported ACT scores no higher than 19 (uncontrolled asthma). Most patients had low biomarker levels based on prespecified cut-points. Baseline mean patient-reported outcome scores were 4.0 (SD 1.4) for AQLQ+12, 2.7 (SD 1.4) for MiniRQLQ, and 47.7 (SD 28.9) for WPAI:Asthma percentage of activity impairment and 33.5 (SD 28.7) for percentage of overall work impairment. The population initiating omalizumab in PROSPERO reported poorly controlled asthma and a substantial disease burden. Clinical

    Previous studies showed that general practitioners have problems in diagnosing asthma accurately, resulting in both under and overdiagnosis. To support general practitioners in their diagnostic process, an asthma diagnostic consultation service was set up. We evaluated the performance of this asthma diagnostic consultation service by analysing the (dis)concordance between the general practitioners working hypotheses and the asthma diagnostic consultation service diagnoses and possible consequences this had on the patients' pharmacotherapy. In total 659 patients were included in this study. At this service the patients' medical history was taken and a physical examination and a histamine challenge test were carried out. We compared the general practitioners working hypotheses with the asthma diagnostic consultation service diagnoses and the change in medication that was incurred. In 52% (n = 340) an asthma diagnosis was excluded. The diagnosis was confirmed in 42% (n = 275). Furthermore, chronic rhinitis was diagnosed in 40% (n = 261) of the patients whereas this was noted in 25% (n = 163) by their general practitioner. The adjusted diagnosis resulted in a change of medication for more than half of all patients. In 10% (n = 63) medication was started because of a new asthma diagnosis. The 'one-stop-shop' principle was met with 53% of patients and 91% (n = 599) were referred back to their general practitioner, mostly within 6 months. Only 6% (n = 41) remained under control of the asthma diagnostic consultation service because of severe unstable asthma. In conclusion, the asthma diagnostic consultation service helped general practitioners significantly in setting accurate diagnoses for their patients with an asthma hypothesis. This may contribute to diminish the problem of over and underdiagnosis and may result in more appropriate treatment regimens.

    To evaluate the impact of asthma on patients in Brazil, by age group (12-17 years, 18-40 years, and ≥ 41 years). From a survey conducted in Latin America in 2011, we obtained data on 400 patients diagnosed with asthma and residing in one of four Brazilian state capitals (São Paulo, Rio de Janeiro, Curitiba, and Salvador). The data had been collected using a standardized questionnaire in face-to-face interviews. For the patients who were minors, the parents/guardians had completed the questionnaire. The questions addressed asthma control, number of hospitalizations, number of emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. We stratified the data by the selected age groups. The proportions of patients who responded in the affirmative to the following questions were significantly higher in the 12- to 17-year age group than in the other two groups: "Have you had at least one episode of severe asthma that prevented you from playing/exercising in the last 12 months?" (p = 0.012); "Have you been absent from school/work in the last 12 months?" (p age group reported that normal physical exertion was very limiting (p = 0.010 vs. the other groups), whereas 14% of the patients in the ≥ 41-year age group described social activities as very limiting (p = 0.011 vs. the other groups). In this sample, asthma had a greater impact on the patients between 12 and 17 years of age, which might be attributable to poor treatment compliance.

    Full Text Available OBJECTIVE: To evaluate inhaler technique in outpatients with asthma and to determine associations between the correctness of that technique and the level of asthma control. METHODS: This was a cross-sectional study involving patients > 14 years of age with physician-diagnosed asthma. The patients were recruited from the Asthma Outpatient Clinic of the Hospital de Clínicas de Porto Alegre, in the city of Porto Alegre, Brazil. The patients completed two questionnaires (a general questionnaire and an asthma control questionnaire based on the 2011 Global Initiative for Asthma guidelines, demonstrated their inhaler technique, and performed pulmonary function tests. Incorrect inhaler technique was defined as the incorrect execution of at least two of the predefined steps. RESULTS: We included 268 patients. Of those, 81 (30.2% showed incorrect inhaler technique, which was associated with poor asthma control (p = 0.002. Logistic regression analysis identified the following factors associated with incorrect inhaler technique: being widowed (OR = 5.01; 95% CI, 1.74-14.41; p = 0.003; using metered dose inhalers (OR = 1.58; 95% CI, 1.35-1.85; p 2 comorbidities (OR = 3.80; 95% CI, 1.03-14.02; p = 0.045. CONCLUSIONS: In the sample studied, incorrect inhaler technique was associated with poor asthma control. Widowhood, use of metered dose inhalers, low socioeconomic level, and the presence of > 2 comorbidities were associated with incorrect inhaler technique.

    Epidemiological investigations indicate that an Asian dust storm (ADS) can aggravate respiratory disorders. However, the effects of ADS on airway inflammation remain unclear. The aim of this study was to investigate the association of exposure to ADS with airway inflammation. The subjects were 33 adult patients with asthma who measured daily peak flow expiratory (PEF) from March to May 2012. Fractional exhaled nitric oxide (FeNO) was measured before and after ADS. The FeNO values were 13.8±13.7 ppb before the ADS and 20.3±19.0 ppb after the ADS, with no significant difference. There was also no significant association of PEF with ADS exposure. However, the increase of FeNO after ADS exposure was proportional to the decrease of PEF (R=-0.78, P<0.0001). These results suggest that airway inflammation aggravated by ADS exposure may induce a decrease in pulmonary function in some adult patients with asthma.

    Full Text Available Objective: Immune responses can change with exercise. We aimed to show the changes in cytokine levels pre- and post-exercise in patients with asthma. Methods: In this prospective control trial, data of 32 patients with asthma that was under control were classified into two groups, pre- and post-exercise. Serum IL-1β and monocyte IL-1β, IL-2, and IL-10 expressions were evaluated using enzyme-linked immunosorbent assay. The patients were advised to walk for at least 30 min for 4 days/week for 12 weeks. Results: There was no significant difference in demographic properties of the participants. Monocyte IL-1β levels in the pre- and post-exercise groups were 1.99±0.35 and 1.01±0.22 pg/mL, respectively (p=0.003. IL-10 levels in the pre- and post-exercise groups were 1.64±0.02 and 1.21±0.03 pg/mL, respectively (p=0.04. IL-2 levels in the pre- and post-exercise groups were 0.64±0.045 and 0.32±0.09 pg/mL, respectively (p=0.001. However, there was a significant difference in serum IL-1β and monocyte IL-1β, IL-2, and IL-10 levels between the groups (p=0.02, p=0.003, p=0.04, and p=0.001, respectively. Conclusion: Systemic inflammatory parameters that are commonly elevated in asthma may improve by exercise. The elucidation of the mechanism of immune control in patients with asthma is useful for the future treatment of asthma.

    In daily practice, Health-Related Quality of Life (HRQoL) tools are useful for supplementing clinical data with the patient's perspective. To encourage their use by clinicians, the availability of tools that can quickly provide valid results is crucial. A new HRQoL tool has been proposed for patients with asthma and rhinitis: the RhinAsthma Patient Perspective-RAPP. The aim of this study was to evaluate the psychometric robustness of the RAPP using the Item Response Theory (IRT) approach, to evaluate the scalability of items and test whether or not patients use the items response scale correctly. 155 patients (53.5% women, mean age 39.1, range 16-76) were recruited during a multicenter study. RAPP metric properties were investigated using IRT models. Differential item functioning (DIF) was used for gender, age, and asthma control test (ACT). The RAPP adequately fitted the Rating Scale model, demonstrating the equality of the rating scale structure for all items. All statistics on items were satisfactory. The RAPP had adequate internal reliability and showed good ability to discriminate among different groups of participants. DIF analysis indicated that there were no differential item functioning issues for gender. One item showed a DIF by age and four items by ACT. The psychometric evaluation performed using IRT models demonstrated that the RAPP met all the criteria to be considered a reliable and valid method of measurement. From a clinical perspective, this will allow physicians to confidently interpret scores as good indicators of Quality of Life of patients with asthma.

    Severe asthma is a heterogeneous disease, which is characterized by airway damage and remodeling. All triggers of asthma, such as allergens, bacteria, viruses, and pollutants, interact with the airway epithelial cells, which drive the airway inflammatory response through the release of cytokines, particularly IL-25, IL-33, and thymic stromal lymphopoietin (TSLP). To investigate whether the expression of the IL-25, IL-33, and TSLP receptors on the basophil membrane are associated with asthma severity. Twenty-six patients with asthma (11 severe and 15 moderate/mild) and 10 healthy subjects (controls) were enrolled in the study. The results of the basophil activation test and flow cytometry analysis were assessed to investigate basophil membrane expression of IL-25, TSLP, and IL-33 receptors before and after IgE stimulation. IL-25 and IL-33 receptor expression on the basophil membrane at baseline were significantly higher in patients with severe asthma than in those with mild/moderate asthma or healthy subjects, independent of atopy, eosinophilia, asthma control, and exacerbation frequency. Following IgE stimulation, a significantly higher increase in the IL-25 and IL-33 receptors was observed in mild/moderate versus severe asthma. The high expression of the IL-25 and IL-33 receptors on the basophil membrane of patients with severe asthma indicates an overstimulation of basophils by these cytokines in severe asthma. This finding can possibly be used as a biomarker of asthma severity. © 2018 S. Karger AG, Basel.

    Full Text Available We studied the ability of patients not experienced in the use of peak expiratory flow meters to assess the severity of their asthma exacerbations and compared it to the assessment of experienced clinicians. We also evaluated which data of physical examination and medical history are used by physicians to subjectively evaluate the severity of asthma attacks. Fifty-seven adult patients (15 men and 42 women, with a mean (± SD age of 37.3 ± 14.5 years and 24.0 ± 17.9 years of asthma symptoms with asthma exacerbations were evaluated in a University Hospital Emergency Department. Patients and physicians independently evaluated the severity of the asthma attack using a linear scale. Patient score, physician score and forced expiratory volume at the first second (FEV1 were correlated with history and physical examination variables, and were also considered as dependent variables in multiple linear regression models. FEV1 correlated significantly with the physician score (rho = 0.42, P = 0.001, but not with patient score (rho = 0.03; P = 0.77. Use of neck accessory muscles, expiratory time and wheezing intensity were the explanatory variables in the FEV1 regression model and were also present in the physician score model. We conclude that physicians evaluate asthma exacerbation severity better than patients and that physician's scoring of asthma severity correlated significantly with objective measures of airway obstruction (FEV1. Some variables (the use of neck accessory muscles, expiratory time and wheezing intensity persisted as explanatory variables in physician score and FEV1 regression models, and should be emphasized in medical schools and emergency settings.

    There have been few reports of clinical pathway (CP) for treatment of asthma attack, because patients with asthma always admit emergently and the severity varies. We introduced CP so that standard asthma treatment can be widely used, and investigated its clinical usefulness. We designed a new CP for treating asthma attack according to the guideline (Japanese guideline (JGL) and Global Initiative for Asthma (GINA)). 136 patients who admitted to our hospital due to asthma attack from January 1999 to November 2006, were enrolled our study. Excluding cases complicated with pneumonia, COPD or cardiac failure, we evaluated 46 cases treated with the CP comparing with 19 cases treated without the CP. The clinical evaluations include systemic and inhaled steroid use, FEV1.0%, history of asthma, and the duration of asthma attack. Furthermore, we investigated difference between cases with and without prolonged admission. While the rates of systemic and inhaled steroid use in cases without the CP were 57.9% and 52.6% respectively, those in cases with the CP were approximately 100%. Employing the CP, FEV 1.0% at discharge time was elevated from 71.7% to 76.3% and the duration of hospitalization was shortened from 14.2 days to 11.5 days. Mean age of the cases with prolonged admission was higher than the rest. The asthma CP is an effective way for the standard treatment according to the guideline to be used widely even by doctors who are not familiar with asthma treatment. It improves the efficacy of in-hospital treatment.

    The majority of current health literacy tools assess functional skills including reading, writing, and numeracy. Although these tools have been able to underline the impact of such skills on individuals' health behaviour, there is a need for comprehensive measures to examine more advanced skills. The individual's ability to use health-related information considering his/her own health context, and judging positive and negative consequences of their decisions has been conceptualized as judgment skills. The present study used a newly developed judgment skills tool to explore asthma self-management practices. Eighty asthma patients were recruited from medical offices during the year 2013. The questionnaire was self-administered and contained health literacy questions, the judgment skill tool, the Asthma Control Test, and several self-management questions. Sixty-nine percent of participants had adequate health literacy, while 24% and 5% had marginal and inadequate levels, respectively. The high-judgment group referred more to their doctor when experiencing asthma problems t(76)=-2.18, Pskills tool can help identify asthma patients' health information use and reveal how this use may affect some self-management practices. Significance for public healthPatients' health literacy has a great impact on their health behaviours and their health outcomes. Therefore, it has become more and more common to measure health literacy within the healthcare setting to determine the most effective approach to target patients. The measurement of asthma judgment skills contribute to a deeper understanding of patients' asthma self-management in crucial topics for asthma control, and have the advantage of assessing the specific abilities needed for this particular condition, which in turn benefits the translation of the findings from the use of this tool into strategies that directly tackle the needs of asthma patients.

Patients diagnosed with asthma experience a number of problems with regard to everyday activities and functions, which adversely affects their health-related QoL. Aim: The aim of this study is to analyze the sociodemographic factors affecting the QoL of patients with asthma. Patients and methods: The study comprised of 100 patients (73 females and 27 males aged 18–84 years (mean age 45.7 years treated in the Department and Clinic of Internal Diseases, Geriatrics and Allergology, Wroclaw Medical University. All patients with asthma who met the inclusion criteria participated in the study. We used medical record analysis and two questionnaires: the asthma quality of life questionnaire (AQLQ and the asthma control test. Up-to-date sociodemographic data were collected from all participants, including sex, age, marital status, education, and sources of income. Results: The sociodemographic variables that correlated positively with QoL in all domains of the AQLQ were professional activity and higher education level of respondents. Factors that negatively influenced the AQLQ domains were older age and lack of professional activity. Conclusion: This study shows that age, physical work, and lack of professional activity decreased the QoL in this patient group. It was found that higher education contributes to better QoL scores.

    Psychological stress is part of people's lives and can sometimes contribute to exacerbation of allergic diseases such as asthma. Asthma is prevalent in all age groups. Acute asthma attacks can be triggered by stress, thus impacting control of the disease and overall quality of life in these patients. The purpose of this study is to evaluate the presence of psychological stress as a trigger in poorly controlled asthma patients and its implications in their quality of life. A descriptive study was conducted in the city of Manzanillo, Cuba, in the course of one year, from January to December, 2010, which included 33 patients with persistent asthma. They were grouped according to severity as suffering from moderate or severe asthma, and all of them met the criteria for poorly controlled disease. They were surveyed to gather data about family and personal history of atopy, age of first asthma crisis, and environmental as well as other factors. Two surveys were used: a list of indicators of vulnerability to stress and the Asthma Quality of Life Questionnaire (AQLQ). Most patients with poorly controlled asthma were in their forties. Female patients were more frequently affected than men were (28 females or 84.8%, and 5 males or 15.1%), and most patients had a family history of atopic disease. Almost all patients had high vulnerability to stress as well as low overall quality of life in all the areas surveyed. Psychological counseling is advised for asthma patients in order to reduce their stress levels.

    BACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 +\\/- 0.41 to 0.8 +\\/- 0.37 and the mean number of bed days occupied was reduced from 16.6 +\\/- 2.94 to 5.3 +\\/- 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 +\\/- 0.27 to 1.2 +\\/- 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.

    Full Text Available Genetic polymorphisms of CYP1A2 is related to the theophylline metabolism that may affect drug levels in the blood, which can also affect incidence of adverse drug reaction (ADR and clinical outcomes of asthma therapy. The frequency of CYP1A2 polymorphism is known to vary among ethnic. Allegedly the Indonesian population has high frequency of gene variants of CYP1A2*1F. This study aims to determine the profile of CYP1A2*1F gene polymorphism in a sample of nonasthma and asthma in Indonesia with other populations based on the literature. Data were taken on January–June 2014. Blood samples were obtained from 29 nonasthma samples and 16 patients with asthma. After extraction of genomic DNA, CYP1A2*1F gene polymorphisms determined by PCR-RFLP. The results of this study indicate that the CYP1A2*1F gene polymorphism in nonasthma samples was 10.35% (3/29 for C/C, 37.93% (11/29 for the C/A, and 51.72% (15/29 for A/A. The asthmatics genotype have a frequency distribution of C/A genotype of 81.25% (13/16 and A/A of 18.75% (3/16. There was no significant difference (p=0.276 allele frequencies between samples of nonasthma and asthma patients. The frequency of CYP1A2*1F gene in Indonesian population is higher than the population of Egypt, Japan, and UK, but lower compared to Malaysia. It can be concluded that there is no difference in frequency.

    This study was conducted in order to investigate the differences in the respiratory physiology of patients with chronic obstructive pulmonary disease (COPD), asthma-COPD overlap syndrome (ACOS), and asthma with airflow limitation (asthma FL(+)). The medical records for a series of all stable patients with persistent airflow limitation due to COPD, ACOS, or asthma were retrospectively reviewed and divided into the COPD group (n=118), the ACOS group (n=32), and the asthma FL(+) group (n=27). All the patients underwent chest high-resolution computed tomography (HRCT) and pulmonary function tests, including respiratory impedance. The low attenuation area score on chest HRCT was significantly higher in the COPD group than in the ACOS group (9.52±0.76 vs 5.09±1.16, Pbronchial wall thickening on chest HRCT was significantly higher in the asthma FL(+) group than in the COPD group (55.6% vs 25.0%, P<0.01). In pulmonary function, forced expiratory volume in 1 second (FEV1) and peak expiratory flow rate were significantly higher in the asthma FL(+) group than in the ACOS group (76.28%±2.54% predicted vs 63.43%±3.22% predicted, P<0.05 and 74.40%±3.16% predicted vs 61.08%±3.54% predicted, P<0.05, respectively). Although residual volume was significantly lower in the asthma FL(+) group than in the COPD group (112.05%±4.34% predicted vs 137.38%±3.43% predicted, P<0.01) and the ACOS group (112.05%±4.34% predicted vs148.46%±6.25% predicted, P<0.01), there were no significant differences in functional residual capacity or total lung capacity. The increase in FEV1 in response to short-acting β2-agonists was significantly greater in the ACOS group than in the COPD group (229±29 mL vs 72±10 mL, P<0.01) and the asthma FL(+) group (229±29 mL vs 153±21 mL, P<0.05). Regarding respiratory impedance, resistance at 5 Hz and resistance at 20 Hz, which are oscillatory parameters of respiratory resistance, were significantly higher in the asthma FL(+) group than in the COPD group

    Occupational asthma is the most frequently diagnosed occupational lung disease reported to the SWORD (Surveillance of Work-related and Occupational Respiratory Disease) scheme. However, diagnosing occupational asthma is not straightforward, and establishing a link with work may be difficult. This study was undertaken to determine the differences between patients with occupational asthma and those with non-occupational asthma which might help in their diagnosis. Information was collected using a self-completed questionnaire. Questionnaires were distributed to 30 subjects aged 18-65 years at each of two clinics--one for patients with occupational asthma and one for those with cryptogenic and environmental asthma. Replies were received from 26 patients with occupational asthma (87%) and 29 patients with non-occupational asthma (97%). The age of onset was significantly higher for those with occupational asthma (42.6 vs 20.7 years). Significantly more subjects with occupational asthma reported improvement on holiday, whereas no significant difference was found in the numbers reporting worsening of symptoms on work days. Those with occupational asthma were less likely to report seasonal variation in symptoms, exacerbation by allergies, pets and stress, or a family history of asthma. Subjects with occupational asthma were more likely to become unemployed (50% vs 3%). Recognition of some of these features in a patient's history may help in the difficult task of differentiating occupational from non-occupational asthma, potentially avoiding the need for exhaustive investigations in some patients. The high prevalence of holiday improvement among subjects with non-occupational asthma suggested that domestic or environmental allergies arising outside the workplace may have been making an important contribution to ongoing symptoms in these subjects.

One hundred and thirty-six GERD patients with medically refractory asthma with (80 patients) or without HH (56 patients) were enrolled. Gastroesophageal reflux disease was assessed by endoscopy, esophageal manometry, reflux monitoring and symptom questionnaires, and treated with laparoscopic Nissen fundoplication (LNF) or LNF with concomitant hiatal hernia repair (LNF-HHR). The outcome measures included patients' satisfaction and drug independence. The patients with HH had lower esophageal sphincters (P = .005) and higher DeMeester scores (P = .014) than those without HH. After an average follow-up of 24 months, symptom scores were significantly decreased from the preoperative values (P reflux, but also controlled asthma symptoms. © 2017 John Wiley & Sons Ltd.

    Few reports have described the significance of viral respiratory infections (VRIs) in exacerbation of asthma in adult patients. The aim of this study was to elucidate the profiles of VRIs in adult patients with asthma along with their molecular epidemiology.A cross-sectional observational study was conducted at Kyorin University Hospital from August 2012 to May 2015. To identify respiratory pathogens in inpatients and outpatients suffering from asthma attacks, RT-PCR/sequencing/phylogenetic analysis methods were applied alongside conventional microbiological methods. Phylogenetic and pairwise distance analyses of 10 viruses were performed.A total of 106 asthma attack patients enrolled in this study in both inpatient (n = 49) and outpatient (n = 57) settings. The total 106 respiratory samples were obtained from nasopharyngeal swab (n = 68) or sputum (n = 38). Among these, patients with virus alone (n = 39), virus and bacterial (n = 5), and bacterial alone (n = 5) were identified. The ratio of virus-positive patients in inpatient or outpatient to the total cases were 31.1% (n = 33) and 10.4% (n = 11), respectively. The frequency of virus-positive patients was significantly higher in inpatients (75.3%, n = 33) than in outpatients (19.3%, n = 11). Major VRIs included human rhinovirus (HRV) (n = 24), human metapneumovirus (hMPV) (n = 9), influenza virus (Inf-V) (n = 8), and respiratory syncytial virus (RSV) (n = 3) infections with seasonal variations. HRV-A and HRV-C were the most commonly detected viruses, with wide genetic divergence on phylogenetic analysis.Asthmatic exacerbations in adults are highly associated with VRIs such as HRV-A or HRV-C, hMPV, RSV, and Inf-V infections with seasonal variations and genetic divergence, but similar frequencies of VRIs occurred in asthma attack patients throughout the seasons.

    Full Text Available OBJECTIVE: To evaluate the impact of asthma, by gender, in a population sample of asthma patients in Brazil. METHODS: We conducted face-to-face interviews with 400 subjects (> 12 years of age included in a national probability telephone sample of asthma patients in the Brazilian state capitals of São Paulo, Rio de Janeiro, Curitiba, and Salvador. Each of those 400 subjects completed a 53-item questionnaire that addressed five asthma domains: symptoms; impact of asthma on quality of life; perception of asthma control; exacerbations; and treatment/medication. RESULTS: Of the 400 patients interviewed, 272 (68% were female. In relation to respiratory symptoms, the proportion of women reporting extremely bothersome symptoms (cough with sputum, tightness in the chest, cough/shortness of breath/tightness in the chest during exercise, nocturnal shortness of breath, and nocturnal cough was greater than was that of men. Daytime symptoms, such as cough, shortness of breath, wheezing, and tightness in the chest, were more common among women than among men. Women also more often reported that their asthma interfered with normal physical exertion, social activities, sleep, and life in general. Regarding the impact of asthma on quality of life, the proportion of subjects who reported that asthma caused them to feel that they had no control over their lives and affected the way that they felt about themselves was also greater among women than among men. CONCLUSIONS: Among women, asthma tends to be more symptomatic, as well as having a more pronounced effect on activities of daily living and on quality of life.

    Understanding patient preferences and desire for involvement in making medical decisions is important when managing chronic conditions. Previous studies have utilized the Autonomy Preference Index (API) in younger asthmatic patients to evaluate these preferences. To identify factors associated with autonomy, and to determine if autonomy is related to asthma outcomes among older adults. 189 older adults (>55 yr) with persistent asthma were included. Preferences for autonomy were assessed using the API, with a higher score indicating higher desire for autonomy. Scores were separated into two domains of 'information seeking' and 'decision making' preferences. The separated scores were correlated with asthma outcomes and demographic variables. To control for confounding factors, a linear regression analysis was performed. Higher 'decision making' preference scores correlated with female gender (p=0.007), higher education level (p=0.01), and lower depression scores (p=0.04). Regarding outcomes, 'decision making' scores positively correlated with asthma quality of life questionnaire (AQLQ) scores (p=0.01). On linear regression analysis, the AQLQ score remained significantly associated with 'decision making' preference scores (p=0.03). There was no association with asthma control test scores, spirometry values, and healthcare utilization. 'Information seeking' preference scores correlated with education level (p=0.03), but there was no correlation with asthma outcomes. Older asthmatic adults with a greater desire for involvement in decision making have a higher asthma related quality of life. Future studies with the intention to increase patient autonomy may help establish a causal relationship. Copyright © 2018. Published by Elsevier Inc.

    Full Text Available Abstract Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICSs represent the standard of care for the majority of patients. Combination ICS/long-acting beta2-agonists (LABA inhalers are preferred for most adults who fail to achieve control with ICS therapy. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. Regular monitoring of asthma control, adherence to therapy and inhaler technique are also essential components of asthma management. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma.

    It is hypothesized that a good partnership between asthma patients and their physicians has a direct and positive influence on the patients' clinical and patient-reported outcomes. Conversely, poor partnership has a detrimental effect on clinical and patient-reported outcomes. This paper uses data from a real-world observational study to define partnership through matched physician and patient data and correlate the quality of partnership with observed clinical and patient-reported outcomes. Data were drawn from Adelphi's Respiratory Disease Specific Programme, a cross-sectional study of consulting patients in five European countries undertaken between June and September 2009. A range of clinical and patient-reported outcomes were observed allowing analysis of the partnership between 2251 asthma patients and their physicians. Analysis demonstrates that the better the partnership between patient and physician, the more likely the patient is to have their asthma condition controlled (PPartnership is also associated with lower impact on lifestyle (Ppartnership is a contributory factor in the improvement of asthma treatment, and patient education may lead to improvement in a patient's ability to contribute to this. Device satisfaction is one of the markers of good partnership.

    Asthma is a highly heterogeneous disease that can be classified into different clinical phenotypes, and treatment may be tailored accordingly. However, factors beyond purely clinical traits, such as patient attitudes and behaviors, can also have a marked impact on treatment outcomes. The objective of this study was to further analyze data from the REcognise Asthma and LInk to Symptoms and Experience (REALISE) Europe survey, to identify distinct patient groups sharing common attitudes toward asthma and its management. Factor analysis of respondent data (N = 7,930) from the REALISE Europe survey consolidated the 34 attitudinal variables provided by the study population into a set of 8 summary factors. Cluster analyses were used to identify patient clusters that showed similar attitudes and behaviors toward each of the 8 summary factors. Five distinct patient clusters were identified and named according to the key characteristics comprising that cluster: "Confident and self-managing," "Confident and accepting of their asthma," "Confident but dependent on others," "Concerned but confident in their health care professional (HCP)," and "Not confident in themselves or their HCP." Clusters showed clear variability in attributes such as degree of confidence in managing their asthma, use of reliever and preventer medication, and level of asthma control. The 5 patient clusters identified in this analysis displayed distinctly different personal attitudes that would require different approaches in the consultation room certainly for asthma but probably also for other chronic diseases.

    Full Text Available Background. Pulmonary function tests (PFT have been developed to analyze tidal breathing in patients who are minimally cooperative due to age and respiratory status. This study used tidal breathing tests in the ED to measure asthma severity. Design/Method. A prospective pilot study in pediatric patients (3 to 18 yrs with asthma/wheezing was conducted in an ED setting using respiratory inductance plethysmography and pneumotachography. The main outcome measures were testing feasibility, compliance, and predictive value for admission versus discharge. Results. Forty patients were studied, of which, 14 (35% were admitted. Fifty-five percent of the patients were classified as a mild-intermittent asthmatic, 30% were mild-persistent asthmatics, 12.5% were moderate-persistent asthmatics, and 2.5% were severe-persistent. Heart rate was higher in admitted patients as was labored breathing index, phase angle, and asthma score. Conclusions. Tidal breathing tests provide feasible, objective assessment of patient status in the enrolled age group and may assist in the evaluation of acute asthma exacerbation in the ED. Our results demonstrate that PFT measurements, in addition to asthma scores, may be useful in indicating the severity of wheezing/asthma and the need for admission.

    Objective: Based on the hypothesis that airway remodelling is related to the duration of asthma, HRCT scanning should show greater abnormalities in the early-onset than the late-onset asthmatics. It was, therefore, intended to assess the presence and the frequency of airway and parenchymal abnormalities with high-resolution computed tomography (HRCT) in elderly asthmatic patients, and to determine whether these abnormalities are related to the duration of asthma. Patients and methods: Sixty-eight clinically stable asthmatic patients aged ≥60 yr were included in this prospective study. The patients were separated into two groups according to the duration of symptoms as late-onset asthma (n = 31) with disease duration of <5 yr, and early-onset asthma (n = 37) with disease duration of ≥5 yr. All patients were lifelong non-smoker and had been using inhaled beta agonists and inhaled steroids. HRCT-scanning and histamine inhalation test were performed on all patients. Results: In comparison with late-onset asthmatic patients, those with early-onset asthma had significantly higher frequency of emphysema (21.6% versus 0.0%, p = 0.006), bronchial dilatation (13.9% versus 0.0%, p 0.03) and bronchial wall thickness (41.7% versus 12.9%, p = 0.01). Multiple logistic regression analysis identified that early-onset of disease was an independent risk factor for the presence of irreversible HRCT-scan abnormalities in elderly asthmatics [odds ratio (OR): 9.4 (2.7-32.7), p 0.00001]. Conclusion: Present data suggest that HRCT abnormalities in early-onset elderly asthmatics reflect parenchymal and airway changes that become irreversible throughout the long course of the disease

    Long-term outcomes of asthma related to exposure to workplace dampness are not well known. The aim of this study was to evaluate the quality of life (QOL) of patients with asthma related to damp and moldy workplaces and characterize factors influencing QOL. Using a questionnaire, we followed 1267 patients previously examined for suspected occupational respiratory disease related to exposure to damp and moldy indoor environments. In addition to demographic and other background data, the questionnaire included sections on current employment status, QOL, anxiety and depression, somatization, hypochondria, and asthma medication. We compared the QOL of patients with occupational asthma (OA) with that of patients with work-exacerbated asthma (WEA) or symptoms without asthma. Impaired QOL was found among patients diagnosed with OA when they were compared with patients in corresponding environments with WEA or symptoms only. Not working and greater use of asthma medication were major determinants of worse QOL. Psychological factors did not explain the differences between the groups. OA induced by exposure to workplace moisture and molds is associated with QOL deterioration. The impairment is related to being unemployed (due to disability, retirement, job loss or other reasons) and the need for medication.

Methods: The clinical symptoms of 202 elderly patients were assessed with the asthma module of the International Study of Asthma and Allergies in Childhood test, which had been modified for the elderly patients, and the diagnostic routine for chronic obstructive pulmonary disease (COPD, which was based on the Global initiative for chronic Obstructive Lung Disease criteria. Of the 202 patients assessed, 43 were subjected to pulmonary function evaluations (spirometry and FeNO measurements. Results: Of the 202 elderly patients, 34 had asthma (23 definite and eleven probable, 20 met COPD criteria, 13 presented with an overlap of asthma and COPD, and 135 did not fit the criteria for obstructive pulmonary disease. Among the 43 elderly patients who were subjected to FeNO measurements, ten showed altered results (23.2% and 33 had normal results (76.7%. The average value of FeNO in patients with definite and probable asthma undergoing this procedure was 29.2 parts per billion whereas that in nonasthmatic patients was 17.5 parts per billion (P=0.0002. Conclusion: We show a clear relationship between FeNO levels and asthma symptoms and previous asthma diagnoses in elderly patients.

    Despite national disease management plans, optimal asthma management remains a challenge in Australia. Community pharmacists are ideally placed to implement new strategies that aim to ensure asthma care meets current standards of best practice. The impact of the Pharmacy Asthma Care Program (PACP) on asthma control was assessed using a multi-site randomised intervention versus control repeated measures study design. Fifty Australian pharmacies were randomised into two groups: intervention pharmacies implemented the PACP (an ongoing cycle of assessment, goal setting, monitoring and review) to 191 patients over 6 months, while control pharmacies gave their usual care to 205 control patients. Both groups administered questionnaires and conducted spirometric testing at baseline and 6 months later. The main outcome measure was asthma severity/control status. 186 of 205 control patients (91%) and 165 of 191 intervention patients (86%) completed the study. The intervention resulted in improved asthma control: patients receiving the intervention were 2.7 times more likely to improve from "severe" to "not severe" than control patients (OR 2.68, 95% CI 1.64 to 4.37; p<0.001). The intervention also resulted in improved adherence to preventer medication (OR 1.89, 95% CI 1.08 to 3.30; p = 0.03), decreased mean daily dose of reliever medication (difference -149.11 microg, 95% CI -283.87 to -14.36; p=0.03), a shift in medication profile from reliever only to a combination of preventer, reliever with or without long-acting beta agonist (OR 3.80, 95% CI 1.40 to 10.32; p=0.01) and improved scores on risk of non-adherence (difference -0.44, 95% CI -0.69 to -0.18; p=0.04), quality of life (difference -0.23, 95% CI -0.46 to 0.00; p=0.05), asthma knowledge (difference 1.18, 95% CI 0.73 to 1.63; p<0.01) and perceived control of asthma questionnaires (difference -1.39, 95% CI -2.44 to -0.35; p<0.01). No significant change in spirometric measures occurred in either group. A pharmacist

    In spite of a decline in mortality due to asthma in Germany various studies point towards deficits in asthma care. Our investigation should collect data about ambulatory care from the view of statutory health insured patients (SHI), who participate in the disease management program asthma (DMP-P) or do not (NP). Primary question was, if there is a difference between asthma control. Secondary questions referred to process parameters. The postal inquiry was conducted in 2010 with 8000 randomly selected members of a SHI company with asthma (4000 DMP-P and 4000 NP). The descriptive evaluation of categorical items was performed with cross-tables. The absolute risk reduction (ARR) and 97.5 %-confidence interval (CI; multiple level 5 %) was used to evaluate the primary question. Secondary questions were analysed by ARR and 95 %-CI. The response rate of the questionnaire accounted for 31.1 % (2565). 49.2 % of all respondents lived with an uncontrolled asthma with no differences between DMP-P and NP (ARR -2.7 %, 97.5 %-CI -7.9 -2.4 %). Results did not alter after adjustment for sex and age. The secondary questions revealed significant differences (DMP-P vs. NP) in participation in asthma trainings 50.6 vs. 32.3 %, use of a peak-flow-meter 49.3 vs. 25.3 % and asthma action plan within reach 21.7 vs. 11.0 %. Half of all respondents lives selfreported - even in the DMP-group - with an uncontrolled asthma. Process parameters showed better results in the DMP-group. It can be considered, that the DMP has its desired effect on patient-centered care, but does not lead to a better therapeutic outcome. Explanations can only be assumed: insufficient impact of the process parameters on the outcome, patient behavior, that minimizes a possible effect, or selection effects, if patients, who were more sick and at the same time more motivated, were mainly included in the DMP. These aspects should be addressed in studies with a prospective design. © Georg Thieme

    Despite great efforts in establishing optimal asthma management, asthma may remain uncontrolled. To effectively manage chronic diseases, such as asthma, it is important to train patients in self-management skills. The aim of this study was to assess the potential benefit of standardised asthma education in Switzerland for asthma control and patients' perception of received asthma care and of self-management support. For this multicentre longitudinal controlled study, asthma patients were recruited in Switzerland. The Asthma Control Test (ACT) was used to assess asthma control. The Patient Assessment of Chronic Illness Care questionnaire (PACIC 5A) was applied to evaluate received health-care services and self-management support. Patients were offered the possibility to attend asthma education sessions conducted by the Swiss Lung League and Swiss Allergy Centre. After 1 year, attenders and non-attenders completed the questionnaires again. Changes in ACT and PACIC 5A scores were analysed using dependent t tests. Overall, 223 patients with asthma were investigated (mean age 43 ± 12 years, 38% male, 13% current smokers, 29% ex-smokers). Sixty-one (27%) patients attended education sessions. Both groups had improved asthma control at follow-up (attenders: t(56) = -3.2, r = 0.4 [medium effect size], p = 0.002; non-attenders: t(141) = -2.6, r = 0.2 [small effect size], p = 0.010). Attenders improved in PACIC and 5A sum scores (t(50) = -3.6, r = 0.5 [medium effect size], p = 0.001). A comprehensive self-management asthma education programme in Switzerland improved asthma control and patients' perception of received asthma care and of self-management support. Professionals should motivate patients to attend asthma education in order to become active partners in managing their disease. © 2017 S. Karger AG, Basel.

    Health-related productivity loss is an important, yet overlooked, component of the economic burden of disease in asthma patients of a working age. We aimed at evaluating the effect of comorbidities on productivity loss among adult asthma patients. In a random sample of employed adults with asthma, we measured comorbidities using a validated self-administered comorbidity questionnaire (SCQ), as well as productivity loss, including absenteeism and presenteeism, using validated instruments. Productivity loss was measured in 2010 Canadian dollars ($). We used a two-part regression model to estimate the adjusted difference of productivity loss across levels of comorbidity, controlling for potential confounding variables. 284 adults with the mean age of 47.8 (SD 11.8) were included (68 % women). The mean SCQ score was 2.47 (SD 2.97, range 0-15) and the average productivity loss was $317.5 per week (SD $858.8). One-unit increase in the SCQ score was associated with 14 % (95 % CI 1.02-1.28) increase in the odds of reporting productivity loss, and 9.0 % (95 % CI 1.01-1.18) increase in productivity loss among those reported any loss of productivity. A person with a SCQ score of 15 had almost $1000 per week more productivity loss than a patient with a SCQ of zero. Our study deepens the evidence-base on the burden of asthma, by demonstrating that comorbidities substantially decrease productivity in working asthma patients. Asthma management strategies must be cognizant of the role of comorbidities to properly incorporate the effect of comorbidity and productivity loss in estimating the benefit of disease management strategies.

    Full Text Available The incidence of a positive family history with asthma and levels of serum IgE and IgE antibodies were examined in 136 patients with asthma in relation to age at onset of the disease. The frequency of subjects with a family history of asthma ranged from 37.9 to 75.0% in all groups classified by age at onset. The frequency of patients with a high serum IgE level (≥ 150 IU/mL was higher (51.7–63.2% in all groups than the frequency of patients with a low serum level (< 150 IU/mL. The mean level of serum IgE was significantly higher in patients with a family history than in those without a family history, in subjects between the ages of 50 and 59 years at onset (mean age 63.4 years; P < 0.02 and in those over the age of 60 years at onset (74.0 years; P < 0.01. The number of patients with a positive RAST score either to house dust mite (HDM, cockroach, and Candida tended to decrease as the age at onset increased. However, the frequency of positive RAST to HDM was higher in patients with a family history and who were over the age of 50 years at onset compared with those patients between the ages of 40 and 49 years at onset, although the frequency was significantly higher in patients with family history than in those without family history (P < 0.02. These results suggest that IgE-mediated allergic reactions are significant not only in those patients who are younger, but also in elderly patients with asthma.

    Asthma is one of the most frequently targeted chronic diseases in the medication therapy management (MTM) programs of the Medicare prescription drug (Part D) benefits. Although racial and ethnic disparities in meeting eligibility criteria for MTM services have been reported, little is known about whether there would be similar disparities among adults with asthma in the United States. Adult patients with asthma (age ≥ 18) from Medical Expenditure Panel Survey (2011-2012) were analyzed. Bivariate analyses were conducted to compare the proportions of patients who would meet Medicare MTM eligibility criteria between non-Hispanic Blacks (Blacks), Hispanics and non-Hispanic Whites (Whites). Survey-weighted logistic regression was performed to adjust for patient characteristics. Main and sensitivity analyses were conducted to cover the entire range of the eligibility thresholds used by Part D plans in 2011-2012. The sample included 4,455 patients with asthma, including 2,294 Whites, 1,218 Blacks, and 943 Hispanics. Blacks and Hispanics had lower proportions of meeting MTM eligibility criteria than did Whites (P asthma. Future studies should examine the implications of such disparities on health outcomes of patients with asthma and explore alternative MTM eligibility criteria.

    Full Text Available Objective: Although many children with asthma can be diagnosed clinically, chest radiographs are routinely requested in asthma attacks. The aim of this study is to determine how often chest radiographs are requested and the factors affecting these requests in pediatric patients with asthma. Methods: This cross-sectional study was performed by studying the electronic radiographic records of pediatric patients with asthma who were referred to our Pediatric Allergy and Immunology Department over a six-month period. A questionnaire was designed to obtain further information from the parents of the patients. Results: The records of 100 children with bronchial asthma, aged 21 to 192 months, were evaluated. The average number of chest radiographs was 3.9±3.8 (between 1-30. Fifty-one percent of the children underwent three or more chest radiographs. There was a positive correlation between the number of chest X-rays before asthma diagnosis and the frequency of antibiotic usage (r=0.222, p=0.026. An inverse correlation was found between the number of chest radiographs and the patients’ ages and the age at which asthma was diagnosed (r=−0.335, p=0.001; r=−0.211, p=0.035, respectively. In contrast, there was a positive correlation between the number of chest X-rays and the number of hospital admissions (r=0.205, p=0.040. A positive correlation between the frequency of antibiotic usage and the annual number of hospital admissions was determined (r=0.428, p=0.000. Furthermore, a positive correlation between the frequency of antibiotic usage and the frequency of asthma attacks was observed (r=0.292, p=0.003. Conclusion: The results of our study show that the use of chest radiographs is high in cases of childhood asthma, especially in younger children.

    Background-Airway inflammation plays an important pathophysiological role in asthma. Eosinophils produce hypobromite and bromotyrosine while neutrophils produce hypochlorite and chlorotyrosine. Objective-To evaluate halotyrosine modifications of individual airway proteins as a marker of inflammation in asthma using an antibody-based assay. Methods-We developed a novel monoclonal antibody (BTK-94C) that binds halogenated tyrosine residues, and used this antibody in a custom enzyme-linked immunosorbent assay (ELISA) microarray platform to examine halotyrosine levels in 23 proteins in three independent sets of sputum samples (52 samples total). Results-In 15 subjects with either no asthma, or with asthma characterized by high or low sputum eosinophil counts, we found associations between increased halotyrosine levels of at least three proteins and severity of airway hyperresponsiveness (AHR). Treatment with mepolizumab in 17 patients with sputum eosinophilia markedly reduced the sputum eosinophilia and significantly reduced halotyrosine levels in one sputum protein. Further analysis of 10 subjects with neutrophilic asthma and 10 health controls demonstrated a broad increase in halotyrosine in the patients with airway neutrophilia. Conclusions-Significantly higher levels of halotyrosine are associated with asthma in the asthma phenotypes we examined. The halotyrosine levels correlated with indirect AHR in the form of exercise-induced bronchoconstriction. Clinical Implication-An antibody-based assay for tyrosine halogenation in specific proteins may prove useful for assessing airway inflammation in asthma. Capsule Summary-An antibody to measure protein monobrominated tyrosine and other halotyrosine modifications was developed and used to evaluate halogenation in specific proteins in the airways for the first time. Associations were found between levels of halotyrosine and exercise-induced bronchoconstriction, and eosinophil and neutrophil inflammation in sputum from

  5. Therapy with omalizumab for patients with severe allergic asthma improves asthma control and reduces overall healthcare costs.

    BACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 ± 0.41 to 0.8 ± 0.37 and the mean number of bed days occupied was reduced from 16.6 ± 2.94 to 5.3 ± 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 ± 0.27 to 1.2 ± 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.

    Chronic respiratory system diseases become serious public health problem all over the world. The most prevalent are obstructive diseases (asthma and COPD). The prevalence of asthma is still high and concern patients representing wide range of age and socio-economic status. Despite progress in diagnostic and therapeutic options several studies showed that asthma has an impact on health-related quality of life and patients' coping. Asthma as chronic condition results in limitations of patients activity and social relations. Thus psychosocial variables, which may have an impact on asthma symptoms presentation and disease progress, should be considered. There are only few reports concerning cognitive functions in asthma. The aim of the study was to assess the potential impact of psychosocial factors on asthma symptoms presentation, and cognitive function in asthma patients.

    Objectives It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Design Qualitative study using semistructured interviews. Setting Primary and secondary care in Brighton and Hove, UK. Participants 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Results Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a ‘narrow’, ‘medical’ questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be ‘non-medical’. The LWAQ was described as a ‘test’ and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Conclusions Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma. PMID:28007706

    Omalizumab, an anti-immunoglobulin E monoclonal antibody, is approved by the U.S. Food and Drug Administration for the management of patients with allergic asthma and with refractory disease, and has also proven beneficial in the management of selected patients with chronic rhinosinusitis (CRS). The common airway model indicates that patients with both allergic asthma and CRS may be more challenging to manage clinically. This is the first study to evaluate the response of omalizumab in patients with asthma and CRS versus those with asthma alone. To compare pulmonary function test (PFT) responses in omalizumab-treated patients with asthma with CRS with omalizumab-treated patients with asthma without CRS. This was a retrospective case-control study at a tertiary university clinic. Between 2007 and 2014, a total of 259 patients with allergic asthma had been prescribed omalizumab for asthma. Outcome measures were absolute, and the percentage changes in PFT results were compared with the baseline. Overall, 81 patients had serial PFT results available for evaluation, among whom 59 (73%) had CRS. Average treatment duration was 27.2, 27.7, and 25.8 months for the entire sample, for patients with asthma and CRS, and for patients with asthma and without CRS, respectively. Overall, PFT metrics improved across all parameters (forced expiratory volume in 1 second, forced vital capacity, forced expiratory volume in 1 second to forced vital capacity ratio, and forced expiratory flow 25-75%). Significant improvement (p omalizumab manifested some improvement in PFT scores. CRS may add to the overall symptom burden experienced by patients with asthma, especially in those with increasing severity, but comorbid CRS did not adversely impact the therapeutic potential of omalizumab. In fact, the benefit of omalizumab was more likely to be observed in patients with asthma and with CRS than in patients with asthma and without CRS.

    Treatment of asthma does not always comply with asthma guidelines (AG). This may be rooted in direct or indirect resistance on the doctors' and/or patients' side or be caused by the healthcare system. To assess whether patients' concepts and attitudes are really an implementation barrier for AG, we analysed the patients' perspective of a "good asthma therapy" and contrasted their wishes with current recommendations. Using a qualitative exploratory design, topic centred focus group (FG) discussions were performed until theoretical saturation was reached. Inclusion criteria were an asthma diagnosis and age above 18. FG sessions were recorded audio-visually and analysed via a mapping technique and content analysis performed according to Mayring (supported by MAXQDA®). Participants' speech times and the proportion of time devoted to different themes were calculated using the Videograph System® and related to the content analysis. Thirteen men and 24 women aged between 20 and 77 from rural and urban areas attended five FG. Some patients had been recently diagnosed with asthma, others years previously or in childhood. The following topics were addressed: (a) concern about or rejection of therapy components, particularly corticosteroids, which sometimes resulted in autonomous uncommunicated medication changes, (b) lack of time or money for optimal treatment, (c) insufficient involvement in therapy choices and (d) a desire for greater empowerment, (e) suboptimal communication between healthcare professionals and (f) difficulties with recommendations conflicting with daily life. Primarily, (g) participants wanted more time with doctors to discuss difficulties and (h) all aspects of living with an impairing condition. We identified some important patient driven barriers to implementing AG recommendations. In order to advance AG implementation and improve asthma treatment, the patients' perspective needs to be considered before drafting new versions of AG. These issues

  10. Smoking Cessation and the Microbiome in Induced Sputum Samples from Cigarette Smoking Asthma Patients.

    Full Text Available Asthma is a common disease causing cough, wheezing and shortness of breath. It has been shown that the lung microbiota in asthma patients is different from the lung microbiota in healthy controls suggesting that a connection between asthma and the lung microbiome exists. Individuals with asthma who are also tobacco smokers experience more severe asthma symptoms and smoking cessation is associated with improved asthma control. In the present study we investigated if smoking cessation in asthma patients is associated with a change in the bacterial community in the lungs, examined using induced sputum. We found that while tobacco smokers with asthma have a greater bacterial diversity in the induced sputum compared to non-smoking healthy controls, smoking cessation does not lead to a change in the microbial diversity.

    Differences between asthma-COPD overlap syndrome (ACOS) and adult-onset asthma are poorly understood. This study aimed to evaluate these differences in a clinical cohort of patients with adult-onset asthma, as a part of the Seinäjoki Adult Asthma Study (SAAS).188 patients were diagnosed with adult-onset asthma and re-evaluated 12 years after diagnosis. They were divided into three groups based on smoking history and post bronchodilator spirometry values: 1) never- and ex-smokers with obstructive (forced expiratory volume in 1 s (FEV 1 )/forced vital capacity (FVC) ≥0.7) patients with ≥10 pack-years; and 3) ACOS patients with ≥10 pack-years and FEV 1 /FVC obstructive patients with ≥10 pack-years smoking history, respectively. ACOS patients also showed reduced lung function, higher remaining bronchial reversibility and a higher number of comorbidities.This study shows distinct differences in diffusing capacity, blood neutrophil and IL-6 levels, bronchial reversibility, lung function and comorbidities between ACOS and adult-onset asthma. The present findings should be considered in the comprehensive assessment of adult asthma patients. Copyright ©ERS 2017.

    Background Despite national disease management plans, optimal asthma management remains a challenge in Australia. Community pharmacists are ideally placed to implement new strategies that aim to ensure asthma care meets current standards of best practice. The impact of the Pharmacy Asthma Care Program (PACP) on asthma control was assessed using a multi‐site randomised intervention versus control repeated measures study design. Methods Fifty Australian pharmacies were randomised into two groups: intervention pharmacies implemented the PACP (an ongoing cycle of assessment, goal setting, monitoring and review) to 191 patients over 6 months, while control pharmacies gave their usual care to 205 control patients. Both groups administered questionnaires and conducted spirometric testing at baseline and 6 months later. The main outcome measure was asthma severity/control status. Results 186 of 205 control patients (91%) and 165 of 191 intervention patients (86%) completed the study. The intervention resulted in improved asthma control: patients receiving the intervention were 2.7 times more likely to improve from “severe” to “not severe” than control patients (OR 2.68, 95% CI 1.64 to 4.37; p<0.001). The intervention also resulted in improved adherence to preventer medication (OR 1.89, 95% CI 1.08 to 3.30; p = 0.03), decreased mean daily dose of reliever medication (difference −149.11 μg, 95% CI −283.87 to −14.36; p = 0.03), a shift in medication profile from reliever only to a combination of preventer, reliever with or without long‐acting β agonist (OR 3.80, 95% CI 1.40 to 10.32; p = 0.01) and improved scores on risk of non‐adherence (difference −0.44, 95% CI −0.69 to −0.18; p = 0.04), quality of life (difference −0.23, 95% CI −0.46 to 0.00; p = 0.05), asthma knowledge (difference 1.18, 95% CI 0.73 to 1.63; p<0.01) and perceived control of asthma questionnaires (difference −1.39, 95% CI −2.44 to −0.35; p<0

    Sexual limitations play an important role in the quality of life of patients with chronic diseases. Very limited information is available on the impact of asthma on the sexual functioning of these individuals. Cross-sectional, observational, multicenter study. Asthma patients and healthy individuals were recruited. All subjects participated in an interview in which demographic and clinical data were recorded, and completed the Goldberg Anxiety-Depression Scale (GADS) to evaluate the presence of concomitant psychiatric disease. Men also completed the International Index of Erectile Function (IIEF), and women, the Female Sexual Function Index (FSFI). A total of 276cases were included, comprising 172asthma patients (63 men and 109 women) with a mean age of 42 (±14) years, and 104 controls (52men and 51women) with a mean age of 39 (±12) years. Time since onset of asthma was 15 years and severity distribution was: 6.4% intermittent, 17.9% mild persistent, 47.4% moderate, and 28.2% severe. Disease was considered controlled in 57.7%, partially controlled in 28.2%, and uncontrolled in 14.1%. Women with asthma had greater sexual limitations than women in the control group, with a total FSFI score of 22.1 (±9) compared to 26.5 (±6.8), respectively (P<.005). Men with asthma had significantly more severe erectile dysfunction with a total IIEF score of 59.5 (±12.5) compared to 64.3 (±8.2) in male controls (P<.05). An association was also observed between sexual problems and poorer asthma control. Asthma is associated with a poorer sexual quality of life among patients. These results should arouse the interest of healthcare professionals in detecting and alleviating possible sexual limitations among their asthma patients in routine clinical practice.

    Severe asthma management in elderly patients may be difficult because of increased comorbid conditions, polypharmacy, physiologic changes that occur with aging, incorrect use of inhaler devices, and poor adherence. To evaluate the long-term safety and efficacy of the anti-IgE antibody omalizumab in elderly (aged ≥65 years) patients with uncontrolled allergic asthma. The efficiency and adverse effects of omalizumab treatment were evaluated based on data extracted from medical records. Patients were evaluated monthly for efficacy and adverse reactions. Treatment efficacy was evaluated by level of asthma symptom control, using the Global Initiative for Asthma guideline. Nineteen consecutive elderly patients with asthma (female to male ratio, 14:5) formed our cohort. The mean (SD) age, disease duration, and total IgE level were 69.3 (5.8) years, 19.4 (8.6) years, and 299.1 (197.2) IU/mL, respectively. The mean (SD) duration of omalizumab treatment was 35.6 (17.8) months (range, 9-66 months). All the patients had at least 1 perennial inhalant allergen sensitivity and had uncontrolled allergic asthma. Elderly patients experienced no significantly important adverse reaction considered to be related to omalizumab treatment. Only 1 patient had a local adverse reaction and 1 had myalgia that was considered to be drug related. After omalizumab treatment, asthma symptoms were well controlled in 9 patients (47.4%) and partly controlled in 8 patients (42.1%). Two of the patients (10.5%) still had uncontrolled asthma. Our study found that omalizumab is a well-tolerated and effective therapy for elderly patients with uncontrolled asthma. Copyright © 2016 American College of Allergy, Asthma & Immunology.

By using a nationwide prescription database, we identified current patients with asthma (age, 18-44 years) in 2010. Severity was classified as severe versus mild......-moderate asthma according to the level of antiasthma treatment. We investigated prescription drug use, hospitalizations, emergency department visits, and outpatient clinic visits according to severity. RESULTS: Among a nationwide population, we identified 61,583 current patients with asthma. Based on the level...... asthma and low asthma control were not managed by specialist care. Patients with severe asthma with specialist contact more frequently had impaired asthma control compared with subjects not treated by a specialist (44.4% vs 33.1%, P

    In 2011 the Latin America Asthma Insight and Management (LA AIM) survey explored the realities of living with asthma. We investigated perception, knowledge, and attitudes related to asthma among Latin American asthma patients. Asthma patients aged ≥12 years from four Latin American countries (Argentina, Brazil, Mexico, Venezuela) and the Commonwealth of Puerto Rico responded to questions during face-to-face interviews. A sample size of 2,169 patients (approximately 400 patients/location) provided an accurate representation of asthma patients' opinions. Questions probed respondents' views on topics such as levels of asthma control, frequency and duration of exacerbations, and current and recent use of asthma medications. A total of 2,169 adults or parents of children with asthma participated in the LA AIM survey. At least 20% of respondents experienced symptoms every day or night or most days or nights. Although 60% reported their disease as well or completely controlled, only 8% met guideline criteria for well-controlled asthma. 47% of respondents reported episodes when their asthma symptoms were more frequent or severe than normal, and 44% reported seeking acute care for asthma in the past year. Asthma patients in Latin America overestimated their degree of asthma control. The LA AIM survey demonstrated the discrepancy between patient perception of asthma control and guideline-mandated criteria. Additional education is required to teach patients that, by more closely following asthma management strategies outlined by current guidelines more patients can achieve adequate asthma control.

    To compare the degrees of allergic reaction and the cross-reactive allergens for three strains of cockroach (Periplanceta fuliginosa , Periplaneta americana and Blattella germanica) between patients with asthma and allergic rhinitis, the specific IgE(sIgE) in asthma and allergic rhinitis for these three strains of cockroach were determined with ELISA. The results showed that the sIgE positive rates for Periplaneta americana, Periplaneta fuliginosa and Blattella germanica in patients with asthma were 23.5%, 16.0% and 14.8%, respectively. The reactive coincidence rate between Periplaneta americana and Periplaneta fuliginoas was 74.0%, between Periplaneta americana and Blattella germanica was 73.5%, and between Periplaneta fuliginosa and Blattella germanica was 85.0% in asthma patients. The IgE positive rates for Periplaneta americana, Periplaneta fuliginosa and Blattella gerraanica in allergic rhinitis patients were 24.8%, 17.6% and 15.8%, respectively. The reactive coincidence rate between Periplaneta americana and Periplaneta fuliginosa was 73.9%, between Periplaneta americana and Blattella germanica was 75.2%, and between Periplaneta fuliginosa and Blattella germanica was 86.1% in allergic rhinitis patients. There was no significant difference between asthma and allergic rhinitis patients although the sIgE positive rates of allergic rhinitis patients were higher than those of asthma patients for these three strains of cock- roach. All these results indicated that the degrees of allergic reaction are similar between asthma and allergic rhinitis patients and there are some cross-reactive allergic components among these three strains of cockroach.

    2013-11-01

    The Japanese Society of Pediatric Allergy and Clinical Immunology (JSPACI) was started in 1966 and currently has 3613 members as of August 1, 2012. The number of pediatricians specializing in allergies who have been certified by the Japanese Society of Allergology is 817. Among these, there are 125 training directors and training facilities for allergy and clinical immunology. The JSPACI first published an asthma guideline specific for children in 2000, and this has been revised every 3 yrs, contributing to better control of pediatric asthma. Food allergy management guidelines were first developed in 2005, which have helped to improve the care of food allergy patients. Among 514 pediatric training programs by the Japanese Society of Pediatrics, there are 312 facilities routinely performing oral food challenges. Among these, there were already 53 facilities performing oral immunotherapy at the end of 2011, treating 1400 cases of food allergy. The prevalence of pediatric allergic diseases has increased in Japan over the past 50 yrs. A number of International Study of Asthma and Allergies in Childhood surveys have been conducted in the past at specific times. The prevalence of wheezing among children aged 13-14 yrs in 2002 was 13.0%. Multi-year surveys found a 1.5- to 2-fold increase every 10 yrs until 2002. However, according to the latest data in 2012, asthma prevalence seems to have slightly decreased in Japan. Food allergy mainly associated with infantile atopic eczema among infants younger than 1 yr of age is the most common form as with other developed countries. The estimated food allergy prevalence based on data from several surveys is 5-10% among infants (0-6 yrs) and 1-2% among schoolchildren (6-15 yrs). A variety of patients suffering from primary deficiency syndrome have been actively analyzed. Previously, antibody defects and well-defined syndromes with immunodeficiency were analyzed, but recent research is focusing on not only acquired immune

    The goal of asthma therapy is to reduce symptoms to the extent that patients can lead active, unlimited lives and to minimize concern about exacerbations. Unfortunately, despite advances in our understanding of the pathophysiology of asthma and the existence of consensus asthma-management guidelines, patients with asthma still suffer considerable morbidity and, on rare occasions, death. Part of the reason for suboptimal asthma control is poor adherence, by both providers and patients, to the recommended asthma regimens and guidelines. However, even under the ideal circumstances of a motivated patient and a knowledgeable physician, the available asthma drugs are not effective in all patients at all times. The market for asthma drugs has been dynamic; numerous new products have recently been approved for marketing by the Food and Drug Administration. Unfortunately, the products recently approved and those likely to enter the market soon mostly are either reformulations or combinations of established molecules. Developing new drugs to treat asthma, particularly with novel anti-inflammatory properties, should be a priority.

    The etiology of osteoporosis in asthma is complex as various factors contribute to its pathogenesis. The purpose of our study was to investigate the effects of obesity and inhaled steroids, as well as the severity and duration of asthma, on osteoporosis in postmenopausal asthma patients as compared to healthy controls. A total of 46 patients with asthma and 60 healthy female controls, all postmenopausal, were enrolled in our study. Bone mineral density was assessed at the lumbar spine and hip using a Lunar DPX-L densitometer. Bone mineral density (BMD) scores were comparable between the asthmatic and control groups, with average scores of 0.95 +/- 0.29 and 0.88 +/- 0.14 g/cm(2), respectively. Likewise, osteoporosis was diagnosed in a similar percentage of patients in the asthmatic (39.1%) and control (43.3%) groups. Bone fracture was identified in four patients with asthma (8.6%) and in six patients from the control group (10%). We could not detect any relationship between BMD and duration of asthma, asthma severity, inhaled steroids or body mass index (BMI). There was no difference between the two groups with respect to age or years since menopause. Although asthma patients were more likely to be overweight and presented higher BMD scores on average than the control subjects, these differences were not statistically significant. There is a slight positive protective effect of high BMI against osteoporosis in asthma patients, but this effect is overcome by time and menopause status. Therefore, the protective effect of obesity against osteoporosis in asthma patients seems to not be significant.

    The efficacy of omalizumab, an anti-immunoglobulin E (IgE) antibody, has been studied in patients with severe bronchial asthma. We conducted a study to evaluate, on the basis of both objective and subjective measures, the efficacy of omalizumab as a long-term therapy in patients with severe and persistent asthma. Omalizumab was administered subcutaneously every two or four weeks. The results of pulmonary function tests, Asthma Control Test (ACT) and Asthma Health Questionnaire (AHQ)-33 scores, the dosage of methylprednisolone during the 12-month treatment period, and the number of emergency visits prior to the start of treatment with omalizumab were compared in patients pre- and post-treatment with omalizumab. Fourteen patients were enrolled in the study between June 2010 and February 2012. Ten patients completed the study. With omalizumab treatment, there was no improvement in lung function; however, the number of emergency visits (19.3 before treatment vs. 1.2 after treatment, p=0.020) and the dosage of methylprednisolone (871.5mg before treatment vs. 119.0mg after treatment, p=0.046) decreased significantly. ACT and AHQ-33 scores at 16 weeks after treatment were significantly better than baseline scores. Four patients continued treatment with omalizumab for four years, and a reduction in their corticosteroid usage was noted. Long-term omalizumab therapy in our patients was found to significantly reduce corticosteroid usage and the number of emergency visits. Long-term omalizumab therapy was effective and might have potential to reduce the frequency of asthma exacerbations. The trial has not been registered because it is not an intervention study.

    Purpose Omalizumab is the preferred add-on therapy for patients with moderate-to-severe persistent allergic asthma and has demonstrated efficacy and safety in various ethnicities. This study evaluated the efficacy and safety of omalizumab in Chinese patients with moderate-to-severe allergic asthma. Methods This randomized, double-blind, parallel-group, placebo-controlled, phase III study assessed lung function, quality of life, asthma control, and safety of omalizumab after 24-week therapy in Chinese patients (18-75 years of age). Results A total of 616 patients were randomized (1:1) to omalizumab or placebo. The primary endpoint, least squares mean treatment difference (LSM-TD) in morning peak expiratory flow (PEF) (omalizumab vs placebo), at Weeks >20-24 was 8.85 L/min (Full analysis set; P=0.062). Per-protocol analysis set showed significant improvements with LSM-TD of 11.53 L/min in mean mPEF at Weeks >20-24 (P=0.022). The FEV1 % predicted was significantly improved with omalizumab vs placebo from 8 to 24 weeks (after 24-week treatment: LSM-TD=4.12%; P=0.001). At Week 24, a higher proportion of omalizumab-treated patients achieved clinically relevant improvements in standardized AQLQ (58.2% vs 39.3%; LSM=0.51 vs 0.10; Pquality of life, and asthma control in Chinese patients with moderate-to-severe persistent allergic asthma and has a good safety profile.

RESULTS: Bone mineral density (BMD scores were comparable between the asthmatic and control groups, with average scores of 0.95 ± 0.29 and 0.88 ± 0.14 g/cm², respectively. Likewise, osteoporosis was diagnosed in a similar percentage of patients in the asthmatic (39.1% and control (43.3% groups. Bone fracture was identified in four patients with asthma (8.6% and in six patients from the control group (10%. We could not detect any relationship between BMD and duration of asthma, asthma severity, inhaled steroids or body mass index (BMI. There was no difference between the two groups with respect to age or years since menopause. Although asthma patients were more likely to be overweight and presented higher BMD scores on average than the control subjects, these differences were not statistically significant. CONCLUSIONS: There is a slight positive protective effect of high BMI against osteoporosis in asthma patients, but this effect is overcome by time and menopause status. Therefore, the protective effect of obesity against osteoporosis in asthma patients seems to not be significant.

    Differences between the opinions of patients and physicians on the impact of asthma are common. We hypothesised that patient-physician discordance may negatively affect asthma outcome. A total of 2902 patients (61% women, mean age 47 years) with moderate-severe asthma and 231 physicians participated in a prospective study. At the baseline visit, data on demographics, clinical variables, degree of asthma control according to the Asthma Control Test (ACT), basic spirometry and the Hospital Anxiety and Depression Scale (HADS) were collected and an ad hoc questionnaire was completed that allowed the degree of concordance between doctors and patients to be assessed. A scheduled telephone call after 3 months was used to elicit the ACT score and the future risk of asthma. At the final visit at 6 months, the following data were recorded: ACT score, spirometry, HADS score and an ad hoc questionnaire to assess the agreement between the doctor and the patient. Changes in study variables according to patient-physician concordance or discordance were analysed. The rate of patient-physician discordance was 27.2%, with overestimation of disease impact by the physician in 12.3% and underestimation in 14.9%. Patient-physician opinion discordance, particularly in the case of physicians underestimating the impact of asthma, showed worse results with statistically significant differences in ACT score, a higher percentage of patients with poor asthma control and lower HADS scores. The need for hospital and emergency department admissions was also higher. Patient-physician opinion discordance may be contributing to lower symptomatic control and increased future risk, with a higher impact when physicians underestimate the impact of asthma on their patients.

    Chronic rhinosinusitis (CRS) is a highly prevalent inflammatory condition, with significant effects on morbidity and quality of life. Given that other chronic inflammatory conditions have been associated with increased mortality risk, we sought to evaluate the relationship between mortality and CRS including the influence of asthma. Our objective was to determine if CRS, with or without asthma, is associated with altered risk of mortality. Using a statewide population database, we retrospectively identified 27,005 patients diagnosed with CRS between 1996 and 2012, and 134,440 unaffected controls matched 5:1 on birth year and sex. Risk of mortality was determined from Cox models and Kaplan-Meier curves were used to compare survival. A significant interaction between CRS and asthma status was observed in which CRS appeared to confer a protective effect in asthma patients. Asthma, when present, increased mortality in CRS-negative controls (p-interaction risk (hazard ratio [HR] = 0.80; 95% confidence interval [CI], 0.74 to 0.85) compared to controls. However, in patients diagnosed at or before the median age of CRS onset (42 years) independent of asthma status, survival was not improved (HR = 0.98; 95% CI, 0.81 to 1.18). Risk of mortality was greater in CRS with nasal polyps (n = 1643) compared to 25,362 polyp-negative CRS patients (HR = 1.38; 95% CI, 1.09 to 1.77). CRS was associated with lower risk of mortality compared to controls, and appeared to mitigate increased mortality from asthma. We posit that better survival conferred by CRS may be secondary to treatment. However, the etiology of this relationship and the effect of CRS treatment on mortality are unknown. © 2017 ARS-AAOA, LLC.

  14. Omalizumab in the management of patients with allergic (IgE-mediated asthma

    Full Text Available Thomas SandströmDepartment of Respiratory Medicine and Allergy, University Hospital, Umeå, SwedenAbstract: Immunoglobulin E (IgE is central to the pathophysiology of allergic asthma. Omalizumab, an anti-IgE monoclonal antibody, binds to the FcεRI binding site on free IgE. As a result, circulating free IgE is reduced, IgE is prevented from attaching to mast cells and basophils, and FcεRI receptor expression is down-regulated. The inflammatory response to allergens and the acute and chronic effector phases of allergic inflammation are thereby attenuated. In clinical trials in adults and adolescents, omalizumab reduced asthma exacerbations, severe asthma exacerbations, inhaled corticosteroid requirements, and emergency visits, as well as significantly improving asthma-related quality of life, morning peak expiratory flow and asthma symptom scores in patients with severe allergic (IgE-mediated asthma. Results from clinical trials in children (< 12 years are consistent with those in the adult population. It is difficult to predict which patients will respond to omalizumab. Responders to omalizumab should be identified after a 16-week trial of therapy using the physician’s overall assessment. When treatment is targeted to these responders, omalizumab provides a cost-effective therapy for inadequately controlled severe allergic (IgE-mediated asthma. Long-term therapy with omalizumab shows the potential for disease-modification in asthma. Ongoing studies are also evaluating the use of omalizumab in other non-asthma IgE-mediated conditions.Keywords: omalizumab, IgE, allergic asthma

    To modify and evaluate a patient education program for adult asthma patients in consideration of quality criteria for teaching. This was a prospective single-center controlled trial in an inpatient rehabilitation center. The control group (n=215) received the usual lecture-based education program, and the intervention group (n=209) the modified patient education program. Data were assessed at admission, discharge, 6 and 12 months post discharge. The primary outcome was asthma control, the secondary outcomes were asthma knowledge, quality of life, and program acceptance. Analysis of change was performed by ANCOVA for each follow-up, adjusting for baseline values. Statistically significant increases in all health outcomes and in asthma control were maintained in both groups at 12 months: CG: +1.9 (95%-CI 1.3-2.6) IG: +1.6 (95%-CI 0.8-2.3). We observed no significant differences between the programs for asthma control and quality of life. Regarding practical asthma knowledge, after 12 months, a group*time interaction emerged with a small effect size (P=0.06, η2=0.01). The modified program was not superior to traditional patient education concerning asthma control. It permanently increased self-management knowledge. Structured and behavioral patient education fosters patient's disease management ability. Possible ways of improving asthma control need to be explored. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Asthma is a common chronic illness that imposes a heavy burden on all aspects of the patient's life, including personal and health care cost expenditures. To analyze the direct cost associated to uncontrolled asthma patients, a cross-sectional study was conducted to determine costs related to patients with uncontrolled and controlled asthma. Uncontrolled patient was defined by daytime symptoms more than twice a week or nocturnal symptoms during two consecutive nights or any limitations of activities, or need for relief rescue medication more than twice a week, and an ACQ score less than 2 points. A questionnaire about direct cost stratification in health services, including emergency room visits, hospitalization, ambulatory visits, and asthma medications prescribed, was applied. Ninety asthma patients were enrolled (45 uncontrolled/45 controlled. Uncontrolled asthmatics accounted for higher health care expenditures than controlled patients, US$125.45 and US$15.58, respectively [emergency room visits (US$39.15 vs US$2.70 and hospitalization (US$86.30 vs US$12.88], per patient over 6 months. The costs with medications in the last month for patients with mild, moderate and severe asthma were US$1.60, 9.60, and 25.00 in the uncontrolled patients, respectively, and US$6.50, 19.00 and 49.00 in the controlled patients. In view of the small proportion of uncontrolled subjects receiving regular maintenance medication (22.2% and their lack of resources, providing free medication for uncontrolled patients might be a cost-effective strategy for the public health system.

    Full Text Available Plasma from bronchial asthma patients and healthy controls was investigated for the content of lipoxygenase products. After lipid extraction using SEP-PAK C18 Cartridges, the lipoxygenase products were measured by Enzyme-Immunoassay. Elevated chemotactic B4 was found in plasma from asthmatic patients with mean value (483±75 pmoUL, while the mean value in normal healthy donors was (140± 12.1 pmol/L (M±SE. The levels of spasmogenic cysteinyl containing leukotrienes were also very high in the bronchial asthma patients. Elevations of leukotriene B4 and cysteinyl containing leukotrienes were detected during attacks of bronchial asthma. These results suggest that leukotriene B4 may be important in the pathogenesis of bronchial asthma and confirmed that peptidoleukotrienes playa role as chemical mediators during the asthmatic attack.

    The first aim of the study (i) assess the current asthma status of general-practitioner-managed patients receiving regular fixed-dose combination inhaled corticosteroid and long-acting beta 2 agonist (FDC ICS/LABA) therapy and (ii) explore patients' perceptions of asthma control and attitudes/behaviors regarding preventer inhaler use. A cross-sectional observational study of Australian adults with a current physician diagnosis of asthma receiving ≥2 prescriptions of FDC ICS/LABA therapy in the previous year, who were recruited through general practice to receive a structured in-depth asthma review between May 2012 and January 2014. Descriptive statistics and Chi-Square tests for independence were used for associations across asthma control levels. Only 11.5% of the patients had controlled asthma based on guideline-defined criteria. Contrarily, 66.5% of the patients considered their asthma to be well controlled. Incidence of acute asthma exacerbations in the previous year was 26.5% and 45.6% of the patients were without a diagnosis of rhinitis. Asthma medication use and inhaler technique were sub-optimal; only 41.0% of the preventer users reported everyday use. The side effects of medication were common and more frequently reported among uncontrolled and partially controlled patients. The study revealed the extent to which asthma management needs to be improved in this patient cohort and the numerous unmet needs regarding the current state of asthma care. Not only there is a need for continuous education of patients, but also education of health care practitioners to better understand the way in which patient's perceptions impact on asthma management practices, incorporating these findings into clinical decision making.

    There have been no reports on the evaluation of the usefulness of long-term asthma management based on the Japanese Pediatric Guideline for the Treatment and Management of Bronchial Asthma 2005 (JPGL 2005). The purpose of the present study was to retrospectively investigate the records of 350 patients admitted to Yamaguchi University Hospital who had asthma attacks from January 2006 to June 2008. There were 149 patients who were treated for more than 3 months in accordance with the guideline (long-term management group) and 201 who were not (non-long-term management group). The patients were divided into three age groups: 100 infants, 159 toddlers, and 91 schoolchildren. The onset age of asthma in the long-term management group was earlier than that in the non-long-term management group in toddlers and schoolchildren. The white blood cell counts and C-reactive protein levels were higher in the non-long-term management group in schoolchildren, suggesting the complication of some infections. The severity of asthma in the long-term management group was greater than that in the non-long-term management group among all three age groups. There were no significant differences, however, in the severity of asthma attack at admission between the long-term and non-long-term management groups in the three age groups. Patients who had severe asthma tended to be treated with long-term management, which suggests that long-term asthma management according to JPGL 2005 may reduce the severity of asthma attack at that admission, because the severity of asthma in patients undergoing long-term management correlates with the severity of asthma attack.

    Evidence of an increased risk of falls in patients with chronic obstructive pulmonary disease (COPD) exists; however, this has not been studied in elderly asthmatic patients. The aim of the study was to determine the incidence of falls in elderly patients who were diagnosed with bronchial asthma compared to subjects with COPD. A 12 - month prospective observational study in elderly outpatients with diagnosis of either asthma or COPD was conducted. All of the participants were monitored on the following parameters: falls, comorbidities, drug therapy and The Berg Balance Scale. The rate of falls was shown as an incidence ratio. Cluster analysis for subgroups with similar features was performed on all patients included in the study. Two clusters of frequent fallers were determined. The fall incidence rate in falls per person per year was 1.41 (95% CI: 0.86-1.96) in asthmatic patients and 1.49 (95% CI: 1.05-2.11) in the COPD group. Frequent fallers were more prevalent in the COPD group, with 32% in this group compared to 28% in the groups of patients with asthma. In cluster analysis, frequent fallers were grouped into two models characterized by polytherapy, depression symptoms, hospitalizations, coronary disease, dementia and diagnosis of COPD or asthma. Elderly asthmatic patients presented a high rate of falls, which is comparable to that of patients with COPD.

    Full Text Available BACKGROUND: Body composition is an important parameter for patients with chronic obstructive pulmonary disease (COPD whereas the association between asthma and obesity is not fully understood. The impact of severe refractory asthma (SRA on fat free mass (FFM has not been investigated. METHODOLOGY AND PRINCIPAL FINDINGS: 213 subjects (70 healthy smokers, 71 COPD patients and 72 asthma patients without significant comorbidities were included in the study. In all patients, body composition assessment (using bioelectrical impendance analysis, skinfold and anthropometric measurements and spirometry were performed. Differences in fat free mass index (FFMI between groups were assessed and determinants of FFMI in asthma were evaluated. Patients with SRA had lower values of FFMI compared to patients with mild-to-moderate asthma [18.0(17.3-18.3-19.5(18.4-21.5, p<0.001], despite the fact that they were more obese. The levels of FFMI in SRA were lower than those of GOLD stage I-III COPD and comparable to those of stage IV COPD patients [18.0(17.3-18.3-18.8(17.8-20.1, p = ns]. These differences were present even after proper adjustments for sex, age, smoking status, daily dose of inhaled corticosteroids (ICS and daily use of oral corticosteroids (OCS. In multivariate analysis, independent predictors of FFMI in asthmatic patients were age, use of OCS and the presence of SRA, but not smoking, sex or cumulative dose of ICS used. CONCLUSIONS AND SIGNIFICANCE: SRA is related to the presence of low FFMI that is comparable to that of GOLD stage IV COPD. The impact of this observation on asthma mechanisms and outcomes should be further investigated in large prospective studies.

    Asthma is an important and serious public health problem in Puerto Rico; however, very few studies measuring the association between health care utilization and asthma control levels in adult asthma patients in Puerto Rico have been done. This study is secondary analysis of an observational and cross-sectional database generated by the Latin American Asthma Insights and Management (LA AIM) survey. Our sub-sample consisted of adults 18 years or older living with asthma, representing a total of 343 individuals. This study determined the numbers of ambulatory physician visits, emergency visits to a physician or an emergency room, and hospitalizations that took place the 12 months prior to the survey. Patients were characterized as having well-controlled, partly controlled, or uncontrolled asthma. Descriptive and inferential statistics were performed to detect differences in the mean and number of events for physician visits, emergency visits, and hospitalizations by asthma control groups. After adjusting for age, sex, and chronic health conditions (other than asthma), adult asthma patients with controlled asthma had 92.0% fewer physician visits, 82.5% fewer emergency visits, and 92.2% fewer hospitalizations than did those with uncontrolled asthma. Interventions geared toward controlling asthma symptoms and clinical manifestations in adults asthma patients-which interventions might include strategies for controlling environmental risk factors, increasing patient and family education with regard to asthma management, and boosting the use of appropriate and effective medications-may have significant potential in terms of reducing the direct and indirect costs of asthma, costs that have a critical impact on the whole health care system.

    Purpose Extrafine-particle inhaled corticosteroids (ICS) have greater small airway deposition than standard fine-particle ICS. We sought to compare asthma-related outcomes after patients initiated extrafine-particle ciclesonide or fine-particle ICS (fluticasone propionate or non-extrafine beclomethasone). Methods This historical, matched cohort study included patients aged 12-60 years prescribed their first ICS as ciclesonide or fine-particle ICS. The 2 cohorts were matched 1:1 for key demographic and clinical characteristics over the baseline year. Co-primary endpoints were 1-year severe exacerbation rates, risk-domain asthma control, and overall asthma control; secondary endpoints included therapy change. Results Each cohort included 1,244 patients (median age 45 years; 65% women). Patients in the ciclesonide cohort were comparable to those in the fine-particle ICS cohort apart from higher baseline prevalence of hospitalization, gastroesophageal reflux disease, and rhinitis. Median (interquartile range) prescribed doses of ciclesonide and fine-particle ICS were 160 (160-160) µg/day and 500 (250-500) µg/day, respectively (P<0.001). During the outcome year, patients prescribed ciclesonide experienced lower severe exacerbation rates (adjusted rate ratio [95% CI], 0.69 [0.53-0.89]), and higher odds of risk-domain asthma control (adjusted odds ratio [95% CI], 1.62 [1.27-2.06]) and of overall asthma control (2.08 [1.68-2.57]) than those prescribed fine-particle ICS. The odds of therapy change were 0.70 (0.59-0.83) with ciclesonide. Conclusions In this matched cohort analysis, we observed that initiation of ICS with ciclesonide was associated with better 1-year asthma outcomes and fewer changes to therapy, despite data suggesting more difficult-to-control asthma. The median prescribed dose of ciclesonide was one-third that of fine-particle ICS. PMID:28102056

    Full Text Available Background: Industrialization and urbanization have had a devastating impact on public health. Asthma is considered as one of the major challenges of public health. The purpose of this study was to determine the association between air pollution and the number of asthma patients admitted to hospitals in Kermanshah, Iran. Methods: In this cross-sectional and ecological study, the data on the number of asthma patients, the concentration levels of air pollutants and weather conditions were collected from the city of Kermanshah. To determine the association between asthma patients admitted to hospitals and air pollutants, Poisson regression was used (P<0.05. Results: according to the statistical analysis, air pollutants had significant correlation with each other. Based on the results of multiple Poisson regression, among air pollutants CO and O3 were significantly correlated with the number of asthma patients referred to hospitals, with relative risk of 1.18 and 1.016, respectively, and based on the results of single Poisson regression, among air pollutants NOx, NO, NO2 and CO were significantly correlated with the number of asthma patients referred to hospitals with relative risk of 1.011, 1.012, 1.054 and 1.247, respectively. Conclusion: according to the results of the present study, there was a significant association between air pollutants (mainly carbon monoxide and ozone and the total number of asthma patients referred to the hospitals in Kermanshah.

    Even though there are multiple options for the treatment of asthma, there still exists a fair group of patients with difficult-to-control asthma. We describe for the first time the real-world effects of three-year omalizumab treatment on patients with difficult-to-control asthma, seen in a social security hospital in a Latin American country. Difficult-to-control asthmatic patients from the out-patient clinic of a regional hospital were recruited to receive a three-year omalizumab course. Efficacy parameters were asthma control test (ACT) score; FEV1; daily beclomethasone maintenance dose; and unplanned visits for asthma exacerbations (emergency room (ER), hospitalisations, intensive care). 52 patients were recruited, 47 completed the three-year treatment (42 female, 15-67 years, mean age 43.5). Comparing efficacy parameters of the year before omalizumab with the 3rd year of omalizumab: mean ACT improved from 12.4 to 20.5, mean FEV1 from 66.3% (standard deviation (SD) 19.1%) to 88.4% (SD 16.2%) of predicted, while mean beclomethasone dose reduced from 1750 to 766 mcg/day and there was a significant reduction in patients experiencing ER visits (from 95% to 19%, pomalizumab, two because of an adverse event (anaphylaxis, severe headache, both resolved without sequelae). Omalizumab improved most clinical parameters of Mexican patients with difficult-to-control asthma. Especially the rates of ER visits and hospitalisation were significantly reduced, thus reducing costs. Omalizumab was generally well tolerated. Copyright © 2013 SEICAP. Published by Elsevier Espana.

    Allergen sensitization is influenced by genetic and environmental factors; however, the factors related to sensitizations in patients with rhinitis and asthma in China are largely unknown. This study investigated the factors associated with allergen sensitizations in patients with asthma and rhinitis in China. A cross-sectional survey was performed in 6304 patients with asthma and/or rhinitis from four regions of China. Patients completed a standardized questionnaire related to respiratory and allergic symptoms, family history of allergic diseases, smoking history, environmental exposure, and eating behaviors. They underwent skin-prick tests (SPTs) with 13 common aeroallergens. Blood samples were collected from 2268 of patients for specific IgE (sIgE) measurements against 16 common aeroallergens. Patients with both asthma and rhinitis had higher prevalence of SPT and sIgE positivity to most allergens than those with asthma or rhinitis alone (p history of allergic rhinitis, air-conditioner usage, sleeping on a mattress, and frequently eating meat were associated with increased risk of SPT and sIgE positivity. Using air-conditioner and sleeping on a mattress were further found to be associated with sIgE positivity to mites and molds. However, increased age and fish, fruit, and raw vegetable intake decreased the risk of SPT and sIgE positivity. Family history of allergic rhinitis, male gender, using an air conditioner, sleeping on a mattress, and frequent meat consumption are risk factors for allergen sensitizations, whereas increased age and frequent fish, fruit, and raw vegetable consumption may protect patients with asthma and/or rhinitis from developing sensitizations in China.

We present the cases of two patients with EIB, one with asthma, and one without asthma, who were evaluated at our primary care practice. The first case was a 44-year-old man with a history of seasonal allergic rhinitis but no asthma, who reported difficulty breathing when playing tennis. The second case was a 45-year-old woman who presented with persistent, generally well-controlled asthma, who was now experiencing bouts of coughing and wheezing during exercise. In both cases, an exercise challenge was used to diagnose EIB, and patients were prescribed a short-acting beta agonist to be used immediately before initiating exercise. EIB is a frequently encountered problem among patients presenting to primary care specialists. Affected patients should be made aware of the importance of proactive treatment with a short-acting beta agonist before initiating any exercise.Keywords: asthma, compliance, exercise-induced bronchospasm

    Pulmonary ventilation and perfusion scan using Xe-133 gas and Tc-99m MAA were performed in 18 patients with bronchial asthma to evaluate the regional pulmonary function. The scintigraphic findings were compared with the results of the auscultation and the conventional pulmonary functioning examination (%FVC, %FEV 1.0 ). Ventilation image showed abnormality in 12 (70.6%) out of the asymptomatic 17 patients and perfusion image showed abnormality in 7 (41.2%) out of 17 patients. These 7 patients with abnormality on perfusion image all showed abnormality on ventilation image. The grade of abnormality in scintigraphic findings was compatible with the values of %FVC and %FEV 1.0 . In conclusion Xe-133 ventilation and Tc-99m MAA perfusion scan were useful procedures to estimate the pulmonary function of patients with bronchial asthma. (author)

    The study compares the psychometric properties of four different approaches to patient-assessed health outcomes in asthma, including the Asthma Quality of Life Questionnaire (AQLQ), Newcastle Asthma Symptoms Questionnaire (NASQ), SF-12 and EuroQol. The instruments were administered by means of a self-completed postal questionnaire to 394 patients recruited from general practices in the North East of England. Patients completed a follow-up questionnaire at 6 months. The levels of missing data were assessed and instrument scores compared using correlational analysis. Scores were related to self-reports of smoking behaviour, socioeconomic status and health transition. Responsiveness was assessed using standardized response means. Two hundred and thirty-five patients took part in the study giving a response rate of 59.6%. There was a relatively large amount of missing data for the individualized section of the AQLQ. Correlational analysis provided evidence of convergent validity between the specific instruments; the largest correlation was found between NASQ scores and the asthma symptoms scale of the AQLQ (r = 0.84). The NASQ was found to be the most powerful at discriminating between smokers and non-smokers. All four instruments were linearly related to self-reported asthma transition (Pscope for application in economic evaluation.

This study aimed to investigate a comparison of COPD patients with and without ACOS, focusing on inflammatory biomarkers, in an outpatient COPD cohort.Methods: We conducted a cross-sectional study analyzing prospectively collected data from the Ishinomaki COPD Network registry. All participants were diagnosed with COPD, confirmed by using spirometry, and were aged 40–90 years and former smokers. Patients with features of asthma including both variable respiratory symptoms and variable expiratory airflow limitation were identified and defined as having ACOS. Then, the inflammatory biomarkers such as fractional exhaled nitric oxide level, blood eosinophil count and percentage, total immunoglobulin E (IgE level, and presence of antigen-specific IgE were evaluated.Results: A total of 257 patients with COPD were identified, including 37 (14.4% with ACOS. Patients with ACOS tended to be younger, have a shorter smoking history, and use more respiratory medications, especially inhaled corticosteroids and theophylline. Mean fractional exhaled nitric oxide level was significantly higher in those with ACOS than in those without ACOS (38.5 parts per billion [ppb] vs 20.3 ppb, P<0.001. Blood eosinophil count and percentage were significantly increased in those with ACOS (295/mm3 vs 212/mm3, P=0.032; 4.7% vs 3.2%, P=0.003, respectively. Total IgE level was also significantly higher, and presence of antigen-specific IgE was observed more frequently in patients with ACOS. Receiver operating characteristic curve analysis indicated that the sensitivity and specificity of these biomarkers were relatively low, but combinations of these biomarkers showed high specificity for

    Stakeholder engagement has the potential to develop research interventions that are responsive to patient and provider preferences. This approach contrasts with traditional models of clinical research in which researchers determine the study's design. This article describes the effect of stakeholder engagement on the design of a randomized trial of an intervention designed to improve child asthma outcomes by reducing parental stress. The study team developed and implemented a stakeholder engagement process that provided iterative feedback regarding the study design, patient-centered outcomes, and intervention. Stakeholder engagement incorporated the perspectives of parents of children with asthma; local providers of community-based medical, legal, and social services; and national experts in asthma research methodology and implementation. Through a year-long process of multidimensional stakeholder engagement, the research team successfully refined and implemented a patient-centered study protocol. Key stakeholder contributions included selection of patient-centered outcome measures, refinement of intervention content and format, and language framing the study in a culturally appropriate manner. Stakeholder engagement was a useful framework for developing an intervention that was acceptable and relevant to our target population. This approach might have unique benefits in underserved populations, leading to sustainable improvement in health outcomes and reduced disparities.

    Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with

This article reviews studies of budesonide/formoterol pMDI in patients with persistent asthma, with a particular focus on patient-reported outcomes (eg, perceived onset of effect, patient satisfaction with treatment, health-related quality of life [HRQL], global assessments, sleep quality and quantity, as these measures reflect patient perceptions of asthma control and disease burden. A search of PubMed and respiratory meetings was performed to identify relevant studies. In two pivotal budesonide/formoterol pMDI studies in adolescents and adults, greater efficacy and similar tolerability were shown with budesonide/formoterol pMDI 160/9 µg and 320/9 µg twice daily versus its monocomponents or placebo. In those studies, improvements in HRQL, patient satisfaction, global assessments of asthma control, and quality of sleep also favored budesonide/formoterol pMDI compared with one or both of its monocomponents or placebo. Budesonide/formoterol pMDI has a rapid onset of effect (within 15 minutes that patients can feel, an attribute that may have benefits for treatment adherence.

    To estimate the rate of anxiety and depression in adult asthma patients and examine the possible association with sociodemographic, clinical and other significant variables. Adult asthmatics (n = 203) were recruited from the asthma outpatient clinic and assessed for sociodemographic and clinical profiles, their levels of disability, social support, asthma treatment stigma and personality traits. The Mini International Neuropsychiatric Interview (M.I.N.I) was used to assess for the diagnosis of Anxiety and Depression in comparison with matched healthy controls (n = 205). Seventy (34.5%) of the patients with asthma have a diagnosis of Anxiety or Depression compared with 15 (7.3%) of matched healthy controls and the difference was significant (OR 6.67, 95% CI 3.58-13.04). Although older age, lower income, use of oral corticosteroid, patients perceived severity of asthma, disability, social support and personality traits were initially significant in univariate analysis, a subsequent logistic regression analysis revealed that only disability scores above the group mean (OR 4.50, 95% CI 2.28-8.87) and not having a strong social support (OR 2.88, 95% CI 1.443-5.78) were the only variables independently associated with diagnosis of Anxiety and Depression in the group of patients with asthma. Anxiety and depression are significantly more common in adult outpatients with asthma when compared with healthy control in Nigeria and was significantly associated with levels of disability and social support. These factors should be considered while formulating predictive models for management of psychosocial problems in asthma in this environment.

    Full Text Available Accumulated evidence suggests a relationship between specific allergic processes, such as atopic eczema in children, and an aberrant fecal microbiota. However, little is known about the complete microbiota profile of adult individuals suffering from asthma. We determined the fecal microbiota in 21 adult patients suffering allergic asthma (age 39.43 ± 10.98 years old and compare it with the fecal microbiota of 22 healthy controls (age 39.29 ± 9.21 years old using culture independent techniques. An Ion-Torrent 16S rRNA gene-based amplification and sequencing protocol was used to determine the fecal microbiota profile of the individuals. Sequence microbiota analysis showed that the microbial alpha-diversity was not significantly different between healthy and allergic individuals and no clear clustering of the samples was obtained using an unsupervised principal component analysis. However, the analysis of specific bacterial groups allowed us to detect significantly lower levels of bifidobacteria in patients with long-term asthma. Also, in allergic individuals the Bifidobacterium adolescentis species prevailed within the bifidobacterial population. The reduction in the levels on bifidobacteria in patients with long-term asthma suggests a new target in allergy research and opens possibilities for the therapeutic modulation of the gut microbiota in this group of patients.

    Adherence to inhaled corticosteroids (ICS) remains a major issue for asthma management, even among patients receiving a regular prescription from their doctor. The frequency of deliberate interruption of ICS, and of spontaneous changes of dose, were studied in a population of asthma patients recruited in community pharmacies. Asthma patients (aged 18-50) recruited in community pharmacies reported in self-administered questionnaires their spontaneous interruptions and changes of doses of ICS during the past 3 months. The characteristics of patients who interrupted their therapy or who modified the dose were compared with other patients. The studied population included 252 patients (mean age 35 year-old, females: 59%), of whom 62% had inadequately controlled asthma. Among these patients, 25% had interrupted ICS therapy during the past 3 months, while 21% spontaneously changed the dose. The most reported reason for interrupting ICS was the cessation of symptoms (50%). In multivariate analysis, interrupting ICS was mainly associated with inadequate asthma control (OR=3.1, 95% CI 1.5-6.4), while the strongest association with changing ICS doses was the patients' perception of asthma as a concern in their lives (OR=3.2, 95% CI 1.2-8.4). These results underline a poor understanding of the purpose of ICS therapy by patients. They also highlight the need of therapeutic education to improve the management of the disease.

    Full Text Available Background: Allergic bronchopulmonary mycosis (ABPM is a clinical syndrome associated with immune sensitivity to various fungi notably Aspergillus spp. that colonize the airways of asthmatics. Early diagnosis and treatment with systemic corticosteroids is the key in preventing the progression of the disease to irreversible lung fibrosis. Aims: To study the occurrence of ABPM among asthma patients with fungal sensitization attending a chest clinic of a tertiary hospital of eastern India. The clinico-radiological and aetiological profiles are also described. Materials and Methods: All consecutive patients with asthma presenting to the chest clinic over a period of one year were screened for cutaneous hypersensitivity to 12 common fungal antigens. The skin test positive cases were further evaluated for ABPM using standard criteria. Results: One hundred and twenty-six asthma patients were screened using twelve common fungal antigens; forty patients (31.74% were found to be skin test positive, and ABPM was diagnosed in ten patients (7.93%. Of the 10 cases of ABPM, nine cases were those of allergic bronchopulmonary aspergillosis (ABPA and one case was identified as caused by sensitization to Penicillium spp. A majority of the cases of ABPM had advanced disease and had significantly lower FEV1 compared to non-ABPM skin test positive asthmatics. Central bronchiectasis on high resolution CT scan was the most sensitive and specific among the diagnostic parameters. Conclusion: There is a significant prevalence of ABPM in asthma patients attending our hospital and this reinforces the need to screen asthma patients for fungal sensitisation. This will help in early diagnosis and prevention of irreversible lung damage.

    To investigate the relationship between serum values of magnesium and the parameters of the pulmonary function tests (PFT) in patients with chronic asthma. This study recruited 50 patients with chronic stable asthma and 40 healthy individuals as a control group. Data on age, sex, severity of asthma, PFT, and details of drug therapy were obtained from each group. Serum magnesium, potassium, phosphorus, calcium, and sodium levels were also measured. To evaluate differences between groups, the Student t test or Mann-Whitney U test was performed for continuous variables, and the χ2 test for categorical variables. In the asthma group, 10% (n = 9) of the patients had hypomagnesemia and 5.5% (n = 5) had hypophosphatemia. Patients with asthma were divided into two groups: the hypomagnesemic group (n = 9) and the normomagnesemic group (n = 41). Forced expiratory volume in 1 s (FEV1), FEV1%, peak expiratory flow (PEF), and PEF% were lower in the hypomagnesemic group than in the normomagnesemic group (p = 0.02). Multiple logistic regression analysis revealed a statistically significant association between hypomagnesemia and PFT in the hypomagnesemic asthmatic group. The correlations of age with FEV1, FEV1%, PEF, and PEF% were as follows: p = 0.00, r = 0.29; p = 0.00, r = 0.43; p = 0.03, r = 0.22; p = 0.00, r = 0.38; and p = 0.03, r = 0.22, respectively. The correlation of serum magnesium levels with PFT (FEV1, FEV1%, PEF, PEF%) were as follows: p = 0.001, r = 0.29; p = 0.001, r = 0.43; p = 0.03, r = 0.22; and p = 0.001, r = 0.38, respectively. The other electrolytes were within the normal range in both groups. In this study, hypomagnesemia and hypophosphatemia were found to be the most common electrolyte abnormalities in patients with chronic stable asthma. FEV1, FEV1%, PEF, and PEF% were significantly lower in asthmatic patients with hypomagnesemia compared to asthmatic patients with normomagnesemia. ©2018 The Author(s). Published by S.

  17. The role of the primary care physician in helping adolescent and adult patients improve asthma control.

    Many adolescents and adults with asthma continue to have poorly controlled disease, often attributable to poor adherence to asthma therapy. Failure to adhere to recommended treatment may result from a desire to avoid regular reliance on medications, inappropriate high tolerance of asthma symptoms, failure to perceive the chronic nature of asthma, and poor inhaler technique. Primary care physicians need to find opportunities and methods to address these and other issues related to poor asthma control. Few adolescents or adults with asthma currently have asthma "checkup" visits, usually seeking medical care only with an exacerbation. Therefore, nonrespiratory-related office visits represent an important opportunity to assess baseline asthma control and the factors that most commonly lead to poor control. Tools such as the Asthma Control Test, the Asthma Therapy Assessment Questionnaire, the Asthma Control Questionnaire, and the Asthma APGAR provide standardized, patient-friendly ways to capture necessary asthma information. For uncontrolled asthma, physicians can refer to the stepwise approach in the 2007 National Asthma Education and Prevention Program guidelines to adjust medication use, but they must consider step-up decisions in the context of quality of the patient's inhaler technique, adherence, and ability to recognize and avoid or eliminate triggers. For this review, a literature search of PubMed from 2000 through August 31, 2010, was performed using the following terms (or a combination of these terms): asthma, asthma control, primary care, NAEPP guidelines, assessment, uncontrolled asthma, burden, impact, assessment tools, triggers, pharmacotherapy, safety. Studies were limited to human studies published in English. Articles were also identified by a manual search of bibliographies from retrieved articles and from article archives of the author.

    Two main types of devices are used to facilitate the administration of inhaled corticosteroid (ICS) and long-acting β-agonist (LABA) in combination, dry powder inhalers (DPIs) and pressurized metered-dose inhalers (pMDIs). There are few reports comparing the effects of the two devices, and it is unknown which should be recommended for asthma patients with given sets of characteristics. In the current study, the beneficial effects and side effects associated with DPIs and pMDIs were compared, and the question of which device should be recommended for asthma patients was investigated. A prospective, randomized, crossover, comparative study in adult outpatients with asthma was conducted using salmeterol/fluticasone propionate combination (SFC) 50 μg/250 μg, one inhalation of Adoair ® 250 Diskus ® twice daily or two inhalations of Adoair ® 125 Aerosol twice daily, for 8 weeks. Questionnaires, exhaled nitric oxide (FeNO) tests and pulmonary function tests were administered after the use of each device for 8 weeks, and the results derived from each device were compared. Sixty-eight subjects were included in the final analysis. There were no significant differences between quality-of-life scores, FeNO, spirometry test results and forced oscillation results. With regard to patient preferences, 57.4% preferred the Adoair ® Aerosol and 35.3% preferred the Adoair ® Diskus ® , as determined via the comparative evaluation questionnaire. Although DPI prescription accounts for the predominant market share of combined ICS/LABA in Japan, patients preferred a pMDI device to a DPI device. Compared to DPIs, pMDIs may be the preferential choice for patients with asthma.

    Although digital health tools are increasingly recognized as effective in improving clinical outcomes such as asthma control and medication adherence, few studies have assessed patient experiences and perception of value. The aim of this study was to evaluate patient satisfaction, perception of usability and value, and desire to continue after 12 months of using a digital health intervention to support asthma management. Participants were enrolled in a randomized controlled study evaluating the impact of a digital health platform for asthma management. Participants used electronic inhaler sensors to track medication use and accessed their information in a digital health platform. Electronic surveys were administered to intervention arm participants aged 12 years and older after 12 months of use. The survey assessed asthma control, patient satisfaction with the sensor device, and perception of the usability and value of the digital health platform through closed-ended and open-ended questions. Logistic regression models were used to assess the impact of participants' characteristics on survey completion, satisfaction, and perception of value. Of the 207 intervention arm participants aged 12 years and older, 89 submitted survey responses (42.9% response rate). Of these 89 participants, 70 reported being very satisfied (79%, 70/89) or somewhat satisfied (20%, 18/89) with the inhaler sensor device. Moreover, 93% (83/89) expressed satisfaction with the reports, and 90% (80/89) found the information from the reports useful for learning about their asthma. In addition, 72% (64/89) of the participants reported that they were interested in continuing to use the sensor and platform beyond the study. There were no significant differences in satisfaction with the device or the platform across participants' characteristics, including device type, age, sex, insurance type, asthma control, or syncing history; however, participants with smartphones and longer participation were

    To explore the polarization of migration dynamics of neutrophils isolated from patients with asthma, chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap syndrome (ACOS) compared with healthy smoking and non-smoking controls. Recruited volunteers were classified as healthy controls, healthy smokers, asthma, COPD and ACOS at Nanfang Hospital from April 2013 to June 2014 according to the Global Strategy for the Diagnosis, Management and Prevention of COPD 2011, Global Strategy for Asthma Management and Prevention 2011 and Consensus on Overlap Phenotype COPD-asthma in COPD 2012. Neutrophils were freshly isolated from whole blood with density gradient technique. The proportion of polarized cells with gradient concentration of formyl-Met-Leu-Phe (fMLP) in Zigmond chamber and vital component of Store Operated Calcium Entry (SOCE) (stromal interaction molecule (STIM) 1, 2 and Orai1) in neutrophils was detected by Western blot. Asthma, COPD and ACOS neutrophils demonstrated a higher spontaneous polarization rate versus healthy controls and healthy smokers ((25.05 ± 4.06)%, (16.20 ± 4.46)%, (29.43 ± 5.53)% vs (7.27 ± 0.99)%, (7.06 ± 3.12)%, all P polarization rate ((14.62 ± 2.26)%, (8.00 ± 1.75)%, all P polarization rate than healthy controls and healthy smokers ((2.45 ± 0.54)% vs (5.12 ± 1.28)%, (5.24 ± 1.34)%, all P vs 0.26 ± 0.14, 0.38 ± 0.12; STIM2: 0.52 ± 0.19, 0.22 ± 0.13, 0.24 ± 0.10 vs 0.05 ± 0.03, 0.10 ± 0.06; Orai1: 0.56 ± 0.04, 0.39 ± 0.05, 0.48 ± 0.05 vs 0.13 ± 0.04, 0.13 ± 0.03) (all P < 0.01). Asthma, COPD and ACOS neutrophils are intrinsically different than counterparts from healthy control subjects and healthy smokers. And vital components of SOCE from patient neutrophils are intrinsically up-regulated.

  1. Epidemiology of pollution-induced airway disease in Japan

    Air pollution has been implicated as one of the factors responsible for the increased incidence of allergic diseases seen over recent years. Epidemiological studies in Japan demonstrate that atopic subjects living in urban areas are more likely to suffer from the effects of air pollution, with increased coughing, sputum production, wheezing and throat irritation. Furthermore, animal studies show that high concentrations of pollutant gases can promote airway sensitization. The incidence of allergic Rhinitis and asthma have been shown to be greater in areas where there is heavy traffic and hence high levels of automobile exhaust emissions. Intranasal administration of diesel exhaust particles in mice produces a stimulatory effect on immunoglobulin E production, and a similar finding has also been shown with suspended particulate matter in air. Air pollutants, such as ozone and nitrogen dioxide (NO 2 ), have been shown to stimulate the production of granulocyte-macrophage colony stimulating factor, which may play a vital role in airway hyperreactivity and asthma. In comparative studies of asthma in urban and rural areas, history of airway infection and a younger age of onset were found to be significantly greater in urban areas. When the asthmatic patients were divided into two groups according to environmental NO 2 levels (group I: NO 2 >30 ppb, group II: NO 2 <30 ppb), no significant difference regarding the various parameters was noted between the two groups, except for a greater severity of asthma in adults in group I, and a greater severity in chrildren in group II. These studies imply that air pollution may be one reason for the increase in allergic diseases in Japan, but a definitive conclusion cannot be drawn, and further, investigation is warranted. (au)

    Full Text Available Objective: To observe the small airways function changes of asthmatic patients in different clinical phases and to discuss its clinical significance. Methods: A total of 127 patients diagnosed as asthma were selected randomly and pulmonary function (PF of them was determined by conventional method. Then they were divided into A, B and C group based on PF results. All 34 patients in A group suffered from acute asthma attack for the first time. All 93 patients in B group had been diagnosed as asthma but in remission phase. C Group was regarded as Control group with 20 healthy volunteers. Then FEV1, FEF50%, FEF75% levels of patients in each group were analyzed, and ΔFEV1, ΔFEF75% and ΔFEF50% levels of patients in each group were compared after bronchial dilation test. Results: It was found that most patients in group A and B had abnormal small airways function, and their small airways function was significantly different compared with that of group C (P<0.01. In addition, except for group C, ΔFEF75%,ΔFEF50% levels in A and B group were improved more significantly than ΔFEV1 levels (P<0.01. Conclusions: Asthma patients in acute phase all have abnormal small airways function. Most asthma patients in remission phase also have abnormal small airways function. After bronchial dilation test, whether patients in acute phase or in remission phase, major and small airways function of them are improved, but improvement of small airways function is weaker than that of major airways. This indicates that asthma respiratory tract symptoms in different phases exists all the time and so therapeutic process is needed to perform step by step.

    The aim of this review is to underline the need for an adequate clinical and functional evaluation of respiratory function and asthma control in patients undergoing surgical procedures requiring general anesthesia to obtain useful information for an adequate preoperative pharmacological approach. It has been shown that baseline uncontrolled clinical/functional conditions of airways represent the most important risk factors for perioperative bronchospasm. In nonemergency conditions, asthma patients should undergo clinical/functional assessment at least 1 week before the surgery intervention to obtain, the better feasible control of asthma symptoms in the single patient. Some simple preoperative information given by the patient in preoperative consultation may be sufficient to identify individuals with uncontrolled or poor controlled asthmatic conditions. Spirometric evaluation is essential in individuals with poor control of symptoms, as well as in those patients with uncertain anamnestic data or limited perception of respiratory symptoms, and in those requiring lung resection. A better control of asthma must be considered the 'gold standard' for a patient at 'a reasonable low risk' to develop perioperative/postoperative bronchospasm. International consensus promoted by pulmonologists, anesthesiologists, and allergists might be useful to define a better diagnostic and therapeutic approach.

    With an aging population and an increase in the prevalence of asthma, this disease is becoming more common in the elderly. Nevertheless, the management of severe asthma can be complex, due to an increased risk of uncontrolled disease in patients over 65 years old and partly to the inherent characteristics of old age: comorbidities, underestimation of the role of allergies, poor adherence, difficulties with inhalation devices, etc. We report two cases of women over 75 with severe persistent allergic asthma not controlled by high doses of inhaled corticosteroids and long-acting beta-2-agonists in whom treatment with omalizumab was initiated. Following treatment with omalizumab a decrease in the number and severity of exacerbations, improved asthma control and dose reduction or discontinuation of systemic corticosteroids were observed. The tolerance of omalizumab was good in both cases. Omalizumab is to be considered an effective and well-tolerated therapeutic option for elderly patients with inadequately controlled severe allergic asthma. Copyright © 2015 SPLF.

    Limited data are available on the use of noninvasive ventilation in patients with asthma exacerbations. The objective of this study was to characterize hospital patterns of noninvasive ventilation use in patients with asthma and to evaluate the association with the use of invasive mechanical ventilation and case fatality rate. This cross-sectional study used an electronic medical record dataset, which includes comprehensive pharmacy and laboratory results from 58 hospitals. Data on 13,558 patients admitted from 2009 to 2012 were analyzed. Initial noninvasive ventilation (NIV) or invasive mechanical ventilation (IMV) was defined as the first ventilation method during hospitalization. Hospital-level risk-standardized rates of NIV among all admissions with asthma were calculated by using a hierarchical regression model. Hospitals were grouped into quartiles of NIV to compare the outcomes. Overall, 90.3% of patients with asthma were not ventilated, 4.0% were ventilated with NIV, and 5.7% were ventilated with IMV. Twenty-two (38%) hospitals did not use NIV for any included admissions. Hospital-level adjusted NIV rates varied considerably (range, 0.4-33.1; median, 5.2%). Hospitals in the highest quartile of NIV did not have lower IMV use (5.4% vs 5.7%), but they did have a small but significantly shorter length of stay. Higher NIV rates were not associated with lower risk-adjusted case fatality rates. Large variation exists in hospital use of NIV for patients with an acute exacerbation of asthma. Higher hospital rates of NIV use does not seem to be associated with lower IMV rates. These results indicate a need to understand contextual and organizational factors contributing to this variability. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc.

    Full Text Available We observed sixty patients with allergic bronchial asthma (ABA and 54 with non-allergic bronchial asthma (NABA. Quantitative SOCS3 and SOCS5 mRNA expression was evaluated by means of real-time PCR. Eighteen healthy persons served as a control group. In patients with bronchial asthma (irrespectively of pathogenetic form, a significant increase of SOCS3 transcription factor expression was detected in peripheral blood mononuclears, as compared with control group. This increase was more pronounced in NABA group. The mRNA SOCS5 level was significantly decreased in bronchial asthma patients, as compared to control group, especially, in ABA subgroup rather than in NABA patients. Thus, an increased expression of SOCS3 mRNA in BA patients could be regarded as a protective antiinflammatory response Decrease of SOCS5 mRNA expression in patients with bronchial asthma (being more pronounced in ABA, may be indicative for a deficiency in negative feedback regulation of gene transcription in allergic bronchial asthma.

    Bronchial asthma is one of the most frequent respiratory diseases in childhood. Recurrent emergency department visits for asthma produce anxiety and high costs for the system of health and for the family. It is important to know the factors related to these recurrent emergency department visits to assist the targeting of appropriate future interventions aimed at reducing this avoidable presentation. The objective of the present study was to identify factors associated with recurrent emergency department visits for asthma in children liable to be modified by means of an education program. Data obtained from a survey of parents of 146 pediatric patients with asthma attending an asthma clinic and educational program were examined. Parents completed an asthma knowledge and attitudes questionnaire that also included other socio demographic and illness-related variables, including the number of consultations to emergency department by their children asthma in the previous 6 months. Of the 146 asthmatic patients enrolled, 41 (28.1%) consulted repeatedly to the emergency department for asthma. After controlling for age of the patient, educational level of the parents, and functional severity of the disease, we found that parents who reported that they attended to emergency room because asthma attacks of their children were severe enough to go elsewhere (OR, 4.57; CL95%, 1.76- 11.85; P = 0.002), parents who reported that asthma medications should be administered only in symptomatic moments (OR 278, CL 95%, 1.05 - 7.33, P = 0.038 and parents that did not recognize the fact that asthma attacks can be avoided if medications are administered when there are no symptoms (between asthma attacks) (OR 2.61; CL95%; 1.03 - 7.02; p = 0,045), had a greater probability to attend rapidly the emergency room because of asthma of their children. The fact that parents of asthmatic patients have thought that asthma medications should be administered only in symptomatic patients, that they hadn

    Noncompliance with healthcare undoubtedly has a strong influence on the high prevalence of uncontrolled obstructive diseases. The aim of our study was to evaluate the quality of medical conduct in patients with asthma or chronic obstructive lung diseases (COPD), with encompassed two-levelled system of health care. A survey of general practitioners (GP), allergists and pulmonologists practicing in Poland was performed between September and December 2016. The basic survey included the data concerning the number of treated patients, the course of the visits, treatment regimens and whether the patients follow the instructions of the physician. The specialist survey recorded the details of the specialist visits, their frequency and character, an evaluation of the pharmacological and non-pharmacological therapies and an evaluation of the GP's actions. The basic questionnaire was completed by 807 doctors with an average of 21 ± 9.85 years of medical experience. Most of the interviewed individuals were GPs (56%), followed by pulmonologists (28%) and allergists (16%). The GP reported 47 cases/month with obstructive pulmonary conditions, including 48.94% asthma and 51.06% COPD patients. They diagnosed three new asthma and COPD patients per month. The allergists treated patients with asthma (105 patients/ month), with 19 newly-diagnosed patients/month. The pulmonologists treated fewer asthma cases than COPD: 71 and 98 patients respectively. They reported 14 patients/month of newly-diagnosed COPD cases. The patients took inhaled glucocorticoids and long-acting b adrenoceptor agonists in separate inhalers. The most frequently-used device was a disc. In opinion of the specialists, half of the therapies initiated recently by GPs for patients with asthma and COPD required modifications. There is a disparity between the true state of medical care of asthma and COPD patients and globally-accepted standards.

  9. Evolving Concepts of Asthma

    2015-01-01

    Our understanding of asthma has evolved over time from a singular disease to a complex of various phenotypes, with varied natural histories, physiologies, and responses to treatment. Early therapies treated most patients with asthma similarly, with bronchodilators and corticosteroids, but these therapies had varying degrees of success. Similarly, despite initial studies that identified an underlying type 2 inflammation in the airways of patients with asthma, biologic therapies targeted toward these type 2 pathways were unsuccessful in all patients. These observations led to increased interest in phenotyping asthma. Clinical approaches, both biased and later unbiased/statistical approaches to large asthma patient cohorts, identified a variety of patient characteristics, but they also consistently identified the importance of age of onset of disease and the presence of eosinophils in determining clinically relevant phenotypes. These paralleled molecular approaches to phenotyping that developed an understanding that not all patients share a type 2 inflammatory pattern. Using biomarkers to select patients with type 2 inflammation, repeated trials of biologics directed toward type 2 cytokine pathways saw newfound success, confirming the importance of phenotyping in asthma. Further research is needed to clarify additional clinical and molecular phenotypes, validate predictive biomarkers, and identify new areas for possible interventions. PMID:26161792

    The avoidance of inhaled allergens or tobacco smoke has been known to have favorable effects on asthma control. However, it remains unclear whether other lifestyle-related factors are also related to asthma control. Therefore, a comprehensive study to examine the associations between various lifestyle factors and asthma control was conducted in Japanese asthmatic patients. The study subjects included 437 stable asthmatic patients recruited from our outpatient clinic over a one-year period. A written, informed consent was obtained from each participant. Asthma control was assessed using the asthma control test (ACT), and a structured questionnaire was administered to obtain information regarding lifestyle factors, including tobacco smoking, alcohol drinking, physical exercise, and diet. Both bivariate and multivariate analyses were conducted. The proportions of total control (ACT = 25), well controlled (ACT = 20-24), and poorly controlled (ACT smoking status and alcohol drinking were not associated with asthma control. On the other hand, younger age (smoking, periodical exercise (> 3 metabolic equivalents-h/week), and raw vegetable intake (> 5 units/week) were significantly associated with good asthma control by bivariate analysis. Younger age, periodical exercise, and raw vegetable intake were significantly associated with good asthma control by multiple linear regression analysis. Periodical exercise and raw vegetable intake are associated with good asthma control in Japanese patients.

    The high burden of asthma indicates suboptimal control of this chronic condition. This review describes approaches for establishing asthma control based on an understanding of potential issues in the achievement and maintenance of asthma control, recent changes in asthma management guidelines that facilitate attainment of treatment goals, and the importance of the healthcare provider-patient partnership to emphasize treatment based on asthma control. Review of the published literature, asthma management guidelines, and patient asthma education resources. Asthma control is best achieved by patient-oriented versus disease-oriented management strategies that incorporate a combination of pharmacologic and nonpharmacologic treatment modalities. Tools that assess and monitor asthma may facilitate the achievement and maintenance of asthma control. Key components of an optimal management strategy include solid partnerships between healthcare providers and patients, comprehensive patient and caregiver education, personalized written asthma action plans, patient-reported evaluation of symptom control, appropriate drug therapy, strategies for improving compliance with asthma medication regimens, and a treatment algorithm that outlines the facets of asthma management. Information presented in this article will guide nurse practitioners in helping patients with asthma achieve and maintain long-term disease control.

The currently available studies evaluating response to pharmacological asthma therapy in obese patients show...... that these patients have an altered, in general less favorable, response to both reliever and controller medication compared to normal weight patients. However, at present, the limited available evidence precludes evidence-based recommendations. The 'obesity-related asthma' phenotype has different characteristics......, including association with atopy and type of airway inflammation, compared to 'classic' asthma. Furthermore, weight loss in patients with this phenotype leads to an improvement in symptoms, lung function, and airway responsiveness, as well as a reduction in medication utilization and hospital admissions...

    Budesonide/formoterol as single inhaler was developed for treating asthma patients who are not adequately controlled on glucocorticoides alone. The aim of this study was to evaluate efficacy, safety and patient/physician satisfaction of budesonide/formoterol therapy.Total of 268 asthma patients (120 men, mean age 38.8 +/- 37.2 years, and 148 women, mean age 42.2 +/- 32 years) were included in the study. All patients received budesonide/formoterol bid (640 mcg of budesonide and 18 mcg of formoterol daily) during run-in period for three weeks. Patients were followed during 14 weeks at 5 visits. At each visit lung function (FEV1 and PEF) was measured,presence of side affects was recorded and questionnaire was given to patients and physicians to estimate the level of satisfaction with budesonide/formoterol therapy (1 very unsatisfied to 5 very satisfied). Significant improvement was noticed in FEV1, from 76.25% of predicted value to 86.94% (p < 0.01); and in PEF from 380.84 L/min to 442.29 L/min (p < 0.01) in all patients. At the end of the study patients' satisfaction with budesonide/formeterol therapy was significantly improved comparing with satisfaction with previously taken therapy, in average grade, from 2.94 to 4.56 (p < 0.01), and similar results were noticed with physicians' satisfaction, from 2.60 to 4.41 (p < 0.01). Budesonide/formoterol in single inhaler, significantly improved lung function in patients with asthma.

    Full Text Available In this paper we present a study whose main aim is the measurement of the Health Related Quality of Life (HRQoL of patients with asthma and the presentation of a first draft of normative values as measured by the SF-6D for asthma patients. In addition, we investigate how far non-disease-specific HRQoL measures can distinguish groups in terms of sociodemographic characteristics.The Portuguese versions of the EQ-5D, SF-6D, AQLQ(S and ACQ were administered using personal interviews to a representative sample of the Portuguese population with asthma.Most of the individuals did not report significant problems in the dimensions used, with the exception of the physical functioning, where individuals reported moderate limitations. The mean utility value was 0.86. Male gender, young, single, individuals with high educational attainment level, employed, individuals with high income and those residing in urban areas reported higher utility levels. As expected, those who were in a severe stadium of the disease reported lower mean utility levels than those who were in a less severe stadium of the disease. Normative values for the SF-6D were computed for patients with asthma by gender, age, marital status, educational attainment level, employment status, area of residence and average monthly net income.The preference-based measures used in this study distinguish patient groups with asthma in terms of socio-demographic groups. The normative values can be used in economic evaluation and clinical studies as they incorporate patients’ preferences and translate the value attributed to patients’ health state.

    Bronchial asthma is a clinical syndrome characterized by the reversibility of airway obstruction. Recently it has been suggested that remodeling of the airway causes irreversible airway obstruction which may be responsible for the patient's symptoms. With this background, the purpose of the present study was to assess patients with corticosteroid-dependent asthma by Tc-99m Technegas scintigraphy (Technegas) in both planar and SPECT images. Twelve patients (7 females and 5 males aged 36-72 years with a median age of 60 years: 4 smokers and 8 non-smokers) with oral corticosteroid-dependent asthma were enrolled in this study. Lung ventilation scanning with Technegas in both planar and SPECT images, high-resolution computed tomography, and pulmonary function tests were performed in all patients. The results of Technegas scanning were graded and correlations with other clinical parameters were evaluated. Significant abnormalities were detected by ventilation scintigraphy with Technegas in patients with corticosteroid-dependent bronchial asthma even during remission. Our data demonstrate that airflow obstruction took place in patients with corticosteroid-dependent asthma even during remission. Technegas scanning appears to be a useful radiopharmaceutical for demonstrating airflow obstruction in patients with bronchial asthma. (author)

    Persistent chronic inflammation and impaired lung growth due to asthma in childhood may have long-term impact on pulmonary function and increase susceptibility to chronic obstructive pulmonary disease (COPD) in later life. To investigate whether childhood asthma is associated with adult lung function and the risk of developing COPD among Japanese older adults, a case-control study was conducted in central Japan. A total of 300 patients with COPD aged 50 to 75 years were referred by respiratory physicians, while 400 controls were recruited from the community. All participants underwent spirometric measurements of lung function. Information on childhood asthma, demographic characteristics, and lifestyle characteristics was obtained by face-to-face interview using a structured questionnaire. The prevalence of childhood asthma was higher (P = .015) among the cases (6.3%) than among the control group (2.4%). Childhood asthma was significantly associated with the risk of COPD (adjusted odds ratio 3.32, 95% confidence interval 1.05-10.45). Participants with childhood asthma had lower (P = .010) forced expiratory volume in 1 second (mean 1.63 L, standard deviation [SD] 0.64 L) than those without (mean 2.04 L, SD 0.75 L). However, the adjusted lung function difference did not attain statistical significance after controlling for confounding variables such as age and cumulative smoking exposure. The epidemiological evidence suggested a positive association between childhood asthma and COPD in later life. Further study of the effect of adequate childhood asthma treatment on future risk of COPD should be undertaken. © 2012 APJPH.

    Full Text Available The Saudi Initiative for Asthma (SINA provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system.

    Reslizumab, an anti-interleukin-5 monoclonal antibody, significantly reduces exacerbation frequency and improves lung function, asthma control and quality of life in adults with severe eosinophilic asthma, as demonstrated in Phase III studies. This secondary analysis assessed reslizumab's efficacy in patients receiving baseline treatment per Global Initiative for Asthma (GINA) Step 4 and Step 5 guidelines. Pooled data from duplicate, Phase III, reslizumab versus placebo studies in patients with severe eosinophilic asthma (blood eosinophils ≥400 cells·µL -1 ) were stratified by baseline therapy. Efficacy assessments were exacerbation rates and changes from baseline forced expiratory volume in 1 s (FEV 1 ) and patient-reported outcomes. Of 953 patients, 69% (n=657) and 11% (n=106) were receiving Step 4 and Step 5 therapy, respectively. Compared with placebo, reslizumab reduced exacerbation rates by 53% (95% CI 0.36-0.62) and 72% (95% CI 0.15-0.52), in Step 4 and Step 5 groups respectively. By study end, reslizumab increased FEV 1 in Step 4 and Step 5 groups by 103 mL (95% CI 52-154 mL) and 237 mL (95% CI 68-407 mL), respectively. Reslizumab also improved patient-reported outcomes compared with placebo in both groups. Reslizumab reduces exacerbation rates and improves lung function and patient-reported outcomes in patients with eosinophilic asthma receiving therapy per Steps 4 and 5 of the GINA guidelines.

    Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. To study the risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients by a home based sleep study and its association with atopy. Patients with asthma and COPD were evaluated for OSA symptoms by Epworth sleepiness scale (ESS) and Berlin questionnaire (BQ). ESS score > or = 9 was considered as high risk for OSA. Patients having high risk for OSA by ESS and BQ were further evaluated for OSA by home based sleep study. Skin prick test against common allergens was done to diagnose atopy in these patients. Among 400 patients (229, 57.25% male and 171, 42.75% female) 328 were asthmatics and 72 were COPD patients. ESS and BQ was positive in 11.25% (45/400) and 18.25% (73/400) patients respectively. ESS was positive in 10.67% (35/328) of asthma and 13.88% (10/72) of COPD patients. BQ was positive in 18.29% (60/328) of asthmatic and 18.05% (13/72) of COPD patients. Skin prick test was positive in 74.16% patients. The maximum positivity was found in asthmatics (139/155, 89.68%) compared to COPD patients (16/155, 10.32%). Skin prick test was done for 40 patients out of 73 of Asthma and COPD patients who were found positive by ESS and BQ. 72.5% patients were found to be atopic. Out of 19 patients in whom home polysomnography was done, 13 patients consented for skin prick test with common aeroallergens and 9 (69.23%) patients were found to be atopic. There is an increased risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients. Atopy could be associated with OSA. The association needs to be proved in a larger study.

    The number of human cases of pandemic H1N1 influenza viral infection has increased in Japan since April 2009, as it has worldwide. This virus is widespread in the Yamaguchi prefecture in western Japan, where most infected children exhibited respiratory symptoms. Bronchial asthma is thought to be one of the risk factors that exacerbate respiratory symptoms of pandemic H1N1-infected patients, but the pathogenesis remains unclear. We retrospectively investigated the records of 33 children with pandemic H1N1 influenza viral infection who were admitted to our hospital between October and December 2009 and analyzed their clinical features. The percentage of children with asthma attack, with or without abnormal findings on chest radiographs (pneumonia, atelectasis, etc.), caused by pandemic H1N1 influenza infection was significantly higher than that of children with asthma attack and 2008-2009 seasonal influenza infection. Of the 33 children in our study, 22 (66.7%) experienced an asthma attack. Among these children, 20 (90.9%) did not receive long-term management for bronchial asthma, whereas 7 (31.8%) were not diagnosed with bronchial asthma and had experienced their first asthma attack. However, the severity of the attack did not correlate with the severity of the pulmonary complications of pandemic H1N1 influenza viral infection. The pandemic H1N1 influenza virus greatly increases the risk of lower respiratory tract complications such as asthma attack, pneumonia, and atelectasis, when compared to the seasonal influenza virus. Furthermore, our results suggest that pandemic H1N1 influenza viral infection can easily induce a severe asthma attack, pneumonia, and atelectasis in atopic children without any history of either an asthma attack or asthma treatment. © 2011 John Wiley & Sons A/S.

    Electronic media such as social media (Facebook, Twitter, MySpace), email, and text messaging could be useful in the management of asthma. However, patient use and preferences for electronic media in asthma management is currently unknown. A survey was sent to asthma patients between 12-40 years of age. The survey collected demographic information, use of electronic media, interest in using electronic media to receive asthma information, and interest in using electronic media to communicate with a health care provider about asthma. Free text entries were encouraged. 145 completed surveys were returned. Text messaging, email, and Facebook were used at least weekly by a majority of respondents (82%, 77%, and 65%, respectively). Email was clearly the most preferred method to receive asthma information and to communicate with a physician. There was some interest in using Facebook or text messaging, whereas Myspace and Twitter had minimal interest. On logistic regression analysis, female and Black or Hispanic participants were more likely to have an interest in the use of electronic media for asthma care. Frequent users (>1X/week) of each electronic media type had greater enthusiasm for their incorporation into asthma care. Free text entries revealed that many participants felt social media sites were for connecting with friends rather than for health care, and privacy concerns were also raised. Electronic media offers a novel way to improve asthma care. Email was the most preferred method, though text messaging and social media sites like Facebook may be appropriate for certain patients.

    Full Text Available Physicians have noted dyspnea in severely ill asthmatic patients to be associated with fright or panic; in more stable patients dyspnea may reflect characteristics including lung function, personality and behavioral traits. This study evaluates the symptom of dyspnea in 32 asthmatic patients twice: first when acutely ill and again after an initial response to therapy. Spirometry was performed, dyspnea quantified (Borg scale, and panic assessed with a specialized measure of acute panic (the acute panic inventory (API in the 32 patients before and again after treatment. After treatment, questionnaires to evaluate somatization and panic disorder were also administered. When acutely ill, both the API and all spirometric measures (PEFR; FEV1; IC correlated with dyspnea. Multiple linear regression showed that measures of the API, the peak expiratory flow rate, and female sex taken together accounted for 41% of dyspnea in acute asthma. After treatment, the API again predicted dyspnea while spirometric data did not. Those subjects who described themselves as having chronic panic disorder reported high grades of dyspnea after treatment also. We conclude that interpretations of the self-report of asthma differ between acutely ill and stable asthmatic patients.

    To investigate the perceptions and attitudes towards asthma management of general practitioners, pharmacists and people with asthma in a rural area. Qualitative semistructured interviews. Small rural centre in New South Wales. General practitioners, pharmacists and people with asthma in a rural area. General practitioners perceived that the patient provided a barrier to the implementation of optimal asthma services. They were aware that other health care professionals had a role in asthma management but were not aware of the details, particularly in relation to that of the pharmacist and would like to improve communication methods. Pharmacists also perceived the patient to be a barrier to the delivery of optimal asthma management services and would like to improve communication with the general practitioner. The impact of the rural environment for the health care professionals included workforce shortages, availability of support services and access to continuing education. People with asthma were satisfied with their asthma management and the service provided by the health care professionals and described the involvement of family members and ambulance officers in their overall asthma management. The rural environment was an issue with regards to distance to the hospital during an emergency. General practitioners and pharmacists confirmed their existing roles in asthma management while expressing a desire to improve communication between the two professions to help overcome barriers and optimise the asthma service delivered to the patient. The patient described minimal barriers to optimising asthma management, which might suggest that they might not have great expectations of asthma care.

    Low adherence and poor outcomes provide opportunity for digital coaching to engage patients with uncontrolled asthma in their care to improve outcomes. To examine the impact of a remote digital coaching program on asthma control and patient experience. We recruited 51 adults with uncontrolled asthma, denoted by albuterol use of >2 times per week and/or exacerbations requiring corticosteroids, and applied a 12-week patient-centered remote digital coaching program using a combination of educational pamphlets, symptom trackers, best peak flow establishment, physical activity, and dietary counseling, as well as coaches who implemented emotional enforcement to motivate disease self-management through telephone, text, and email. Baseline and post-intervention measures were quality of life (QOL), spirometry, Asthma Control Test (ACT), Asthma Symptom Utility Index (ASUI), rescue albuterol use, and exacerbation history. Among 51 patients recruited, 40 completed the study. Eight subjects required assistance reading medical materials. Significant improvements from baseline were observed for Patient-Reported Outcomes Measurement Information System mental status (p = 0.010), body weight, and outpatient exacerbation frequency (p = 0.028). The changes from baseline in ACT (p = 0.005) were statistically significant but did not achieve the pre-specified minimum clinically important difference (MCID), whereas for ASUI, the MCID and statistical significance were achieved. Spirometry and rescue albuterol use were no different. A patient-oriented, remote digital coaching program that utilized trained health coaches and digital materials led to statistically significant improvement in mental status, outpatient exacerbations, body weight, and ASUI. Digital coaching programs may improve some outcomes in adults with uncontrolled asthma.

    Limitations in asthma prevalence studies and difficulties in diagnosing pediatric asthma lead to uncertainty over the full extent of mild persistent asthma in children and adolescents. Although recent surveys have reported that the majority of pediatric patients with asthma in the United States...... and Europe have symptoms consistent with mild disease, these surveys have limitations in design. Thus, the true prevalence of mild asthma remains unknown. It is unclear whether children with mild persistent asthma progress to more severe asthma, but the risk of severe asthma exacerbations seems...... to be unrelated to the symptom severity. Clinical studies restricted to pediatric patients with mild asthma are limited, but available data do suggest substantial morbidity of mild persistent asthma in this population and support inhaled corticosteroid intervention.

    Stepwise management of asthma remains an area of evolving research. Asthma is one of the most expensive chronic diseases in the United States; stepwise management is an important area of focus, with several recent guidelines recommending management. This is a review of published English language literature, focusing on management guidelines for asthma in adult and pediatric patients. Asthma is a chronic disease whose assessment of severity allows for therapeutic goals to match the impairment noted. Good evidence exists to aid risk reduction, leading to decreased emergency room visits, preventing loss of lung function in adults and lung growth in children, and optimizing pharmacotherapy with reduced side effects profile. Recent asthma management guidelines incorporate 4 components of asthma care including: monitoring of severity, patient education, controlling external triggers, and medications, including recent attention to medication adherence. Asthma is an expensive chronic disease with preventive measures leading to reduced healthcare costs. Future targeted cytokine therapy to decrease serum and blood eosinophils may become an integral part of asthma management. © 2015 ARS-AAOA, LLC.

    Objective: To explore the role of endothelin and related cytokines (IL-5, IL-6, IL-8) in the development of bronchial asthma in pediatric patients. Methods: Plasma ET-1 (with RIA) and serum IL-5 (with ELISA), IL-6, IL-8 (with RIA) levels were measured in 42 pediatric patients with bronchial asthma and 30 controls. Results: The plasma ET-1 levels in the patients during acute attack (n=22) were significantly higher than those in patients during remission (n=20) as well as in controls (P 0.05). Levels of ET-1 were positively correlated with those of IL-5 (during attack, r=0.560, P<0.01; during remission, r=0.435, P<0.01). Conclusion: ET and the cytokines IL-5, IL-6, IL-8 participated in the pathogenesis of bronchial asthma through different mechanisms and dynamic determination of which could reflect the progression of the disease.

    To delineate the underlying mechanism of microRNA-145 modulate the balance of Th1/Th2 via targeting RUNX3 in asthma patients. Peripheral blood samples were collected from asthma patients and healthy controls. CD4 + T cells were isolated and cultured. Using quantitative PCR detect, the level of microRNA-145 and RUNX3 mRNA level in the CD4 + T cells from asthma patients and healthy controls, meanwhile, western blot was used to detect the RUNX3 protein level. Th1 or Th2 related cytokines were measured by enzyme-linked immunosorbent assay. Dual-Luciferase Reporter Assay was performed to confirm the correlation between microRNA-145 and RUNX3. MicroRNA-145 mimic or inhibitor was transfected in the CD4 + T cells and the changes of RUNX3 level, Th1 or Th2 related cytokines and the percentage of Th1 and Th2 were observed after transfection. MicroRNA-145 level of CD4 + T cells was higher with a lower RUNX3 expression in asthma patients. There is negative correlation between microRNA-145 and RUNX3. Th2 hyperactivity and Th1 deficiency was detected in the CD4 + T cells of asthma patients. Dual-Luciferase Reporter Assay has shown that RUNX3 is a target of microRNA. Up-regulation or down-regulation of miR-145 level caused RUNX3 expression changes in CD4 + T cells and influence the related cytokines. Inhibition of microRNA-145 may reverse the imbalance of Th1/Th2 in asthma patients. MicroRNA-145 could regulate the balance of Th1/Th2 through targeting the RUNX3 in asthma patients. MicroRNA-145 and RUNX3 may be used as biomarkers or targets in the diagnosis or therapy of asthma.

    Asthma is a heterogeneous disease characterized by multiple phenotypes. Treatment of patients with severe disease can be challenging. Predictive biomarkers are measurable characteristics that reflect the underlying pathophysiology of asthma and can identify patients that are likely to respond to a given therapy. This review discusses current knowledge regarding predictive biomarkers in asthma. Recent trials evaluating biologic therapies targeting IgE, IL-5, IL-13, and IL-4 have utilized predictive biomarkers to identify patients who might benefit from treatment. Other work has suggested that using composite biomarkers may offer enhanced predictive capabilities in tailoring asthma therapy. Multiple biomarkers including sputum eosinophil count, blood eosinophil count, fractional concentration of nitric oxide in exhaled breath (FeNO), and serum periostin have been used to identify which patients will respond to targeted asthma medications. Further work is needed to integrate predictive biomarkers into clinical practice.

    Full Text Available Objective: The mechanism of biological treatment molecule called omalizumab used in asthma treatment is thought to be versatile; however, the mechanism still remains unknown. This study was undertaken in severe asthma patients underwent omalizumab treatment, in order to investigate the relationship between biomarker expression and disease characteristics related to the immune system. Methods: Consecutive patients with severe asthma disease (n=15; Group IA, pretreatment and Group IB, post-treatment underwent omalizumab treatment. Control group was age- and sex-matched including 25 healthy in Group II. Blood samples from both the groups were taken during their first visit (Group IA and II and then after 12 months of treatment in asthmatic patients (Group IB. Serum levels of homocysteine (Hcy, eosinophil cationic peptide (ECP, 25-hydroxyvitamin D (25(OHD, interleukin-1β (IL-1β, soluble OX2 (sCD200 and clinical follow-up tests including fractional exhaled nitric oxide (FeNO, asthma control test (ACT, and pulmonary function tests were evaluated. Results: After the treatment, 25(OHD levels and pulmonary function tests, including forced expiratory volume in 1 second (FEV1 and forced vital capacity (FVC levels, were significantly increased. Furthermore, total immunoglobulin E (IgE, Hcy, ECP, FeNO, and sCD200 levels were dramatically diminished. Regression analysis revealed positive correlations between ACT-FEV1 and ACT- FVC and between FeNO-age and FeNO-ECP for Group IA patients. Negative correlations were detected between ACT-IgE, age-FEV1, FeNO-FEV1, and FeNO-FVC for Group IA patients. Conclusion: Our results suggest that the potential use of serum biomolecules in concordance to the clinical status of the asthmatic patients might be a follow-up tool for the omalizumab therapy.

    Length of hospital stay (LOS) of asthma can be a reflection of the disease burden faced by patients, and it is also sensitive to air pollution. This study aims at estimating and validating the effects of air pollution and readmission on the LOS for those who have asthma, considering their readmission history, minimum temperature, and threshold effects of air pollutants. In addition, sex, age, and season were also constructed for stratification to achieve more precise and specific results. The results show that no significant effects of PM 2.5 and NO 2 on LOS were observed in any of the patients, but there were significant effects of PM 2.5 and NO 2 on LOS when a stratifying subgroup analysis was performed. The effect of PM 10 on LOS was found to be lower than that of PM 2.5 and higher than that of NO 2 . SO 2 did not have a significant effect on LOS for patients with asthma in our study. Our study confirmed that the adverse effects of air pollutants (such as PM 10 ) on LOS for patients with asthma existed; in addition, these effects vary for different stratifications. We measured the effects of air pollutants on the LOS for patients with asthma, and this study offers policy makers quantitative evidence that can support relevant policies for health care resource management and ambient air pollutants control.

    Full Text Available Introduction: Almost one third of patients with asthma have symptomatic evidence for coexisting gastroesophageal reflux disease (GERD, which is thought to be aggravating factor in asthma at least in some cases. We investigated the impact of coexisting GERD on asthma severity and parameters of lung function.Methods: Ninety two asthma patients diagnosed according to ATS criteria were studied. After full history and physical examination, asthma severity was measured in each patient using asthma control test (ACT. GERD symptoms was verified in each patient. Impulse oscillometry(IOS and lung volume studies (using body-plethysmography and IOS were performed. Thedifference between total airway resistance (TAWR indicated by resistance at 5 Hz and centralairway resistance (CAWR as indicated by resistance at 20 Hz in oscillometry was calculated and considered as representative of resistance at peripheral airways (PAWR. The relationship between the presences of GERD symptoms, ACT score and parameters of lung function were analyzed.Results: PAWR and TAWR were both significantly higher in asthmatic patients with GERD symptoms than patients without GERD symptoms (256.64±161.21 versus 191.68±98.64; P=0.02,and 102.73±122.39 versus 56.76±71.43; P=0.01, respectively. However, no significant difference was noted in mean values of ACT, FEV1 (forced expiratory volume in 1 sec, FVC (forced vitalcapacity, PEF (peak expiratory flow, and CAWR in these two groups.Conclusion: These findings suggest that the severity of asthma as measured by ACT score is notdifferent in patients with and without GERD symptoms. However, total and peripheral airway resistance measured by IOS is significantly higher in asthmatic patients with GERD symptoms.

    Although airway inflammation is an intrinsic and key feature of asthma, this response varies in its intensity and translation to clinical characteristics and responsiveness to treatment. The observations that clinical heterogeneity is an important aspect of asthma and a feature that likely dictates and determines responses to treatment in severe asthma, patient responsiveness to medication is incomplete, and risks for exacerbation are increased. The development of biologics, which target selected and specific components of inflammation, has been a promising advance to achieve asthma control in patients with severe disease. This article reviews the current biologics available and under development and how their use has affected asthma and which subpopulations appear to benefit the greatest.

    Proper asthma management and control depend on patients having affordable access to healthcare yet financial barriers to asthma care are common. To examine associations of work-related asthma (WRA) with financial barriers to asthma care and adverse asthma outcomes. Cross-sectional, random-digit-dial survey conducted in 37 states and District of Columbia. A total of 27,927 ever-employed adults aged ≥18 years with current asthma. Prevalence ratios (PR) for the associations of WRA with financial barriers to asthma care and of WRA with adverse asthma outcomes stratified by financial barriers. Persons with WRA were significantly more likely than those with non-WRA to have at least 1 financial barrier to asthma care [PR, 1.66; 95% confidence interval (CI), 1.43-1.92]. Individuals with WRA were more likely to experience adverse asthma outcomes such as asthma attack (PR, 1.31; 95% CI, 1.22-1.40), urgent treatment for worsening asthma (PR, 1.57; 95% CI, 1.39-1.78), asthma-related emergency room visit (PR, 1.69; 95% CI, 1.41-2.03), and very poorly controlled asthma (PR, 1.54; 95% CI: 1.36-1.75). After stratifying for financial barriers to asthma care, the associations did not change. Financial barriers to asthma care should be considered in asthma management, and individuals with WRA are more likely to experience financial barriers. However, individuals with WRA are more likely to experience adverse asthma outcomes than individuals with non-WRA, regardless of financial barriers. Additional studies are needed to identify medical, behavioral, occupational, or environmental factors associated with adverse asthma outcomes among individuals with WRA.

    The frequent association of asthma and paranasal sinusitis has been ascribed to a nasobronchial reflex, aspiration of sinus secretions, or enhanced beta-adrenergic blockade. We investigated possible pulmonary aspiration in a pilot study (eight patients) and follow-up study (13 patients) by means of a radionuclide technique. In the pilot study, the aim was to demonstrate aspiration as well as visibility of the radionuclide in the thorax during a period of 24 hours. The radionuclide was initially placed bronchoscopically in the bronchial tree in four patients and was still clearly visible in the same position after 24 hours in three patients. Aspiration from the nasopharynx was unequivocally demonstrated in two of four patients with depressed consciousness. The follow-up study population consisted of four patients with maxillary sinusitis only and nine patients with sinusitis and asthma. The radionuclide was placed in a maxillary sinus during therapeutic puncture. In the patients with only sinusitis as well as patients with asthma and sinusitis the radionuclide could be demonstrated in the maxillary sinus, nasopharynx, esophagus, and lower gastrointestinal tract during a 24-hour period. However, no pulmonary aspiration of radionuclide could be demonstrated in any patient. We conclude that seeding of the lower airways by mucopurulent secretions is unlikely to account for coexistent pulmonary disease. The association is probably related to generalized mucosal disease affecting both upper and lower airways

    To investigate the effect of education on self-evaluation and control level in patients with bronchial asthma. Seventy-five asthmatic patients with the initial diagnosis in line with the American Thoracic Society criteria, including 46 with junior high school education or below (group A) and 29 with senior high school education or above (group B), were asked to complete a survey to assess their symptoms and asthma attacks. Asthma control test (ACT) and peak expiratory flow rate (PEFR) evaluation were performed 8, 12 and 24 weeks after salmeterol/fluticasone therapy. Step-down treatment was administered according to GINA guidelines. The self-evaluation of the patients was assessed according to ACT score, physical signs and pulmonary function. An ACT score over 19 indicate well controlled condition. The effect of education on the self-evaluation and control level of bronchial asthma was assessed. The two groups had similar basal level of pulmonary function (FEV1). Eight weeks after the therapy, 29 patients in group A had ACT score over 19, including 11 with high control level; in group B, 17 had ACT score over 19, of whom 4 showed high control level. There was no significant difference between the two groups in control levels and self-evaluation (P>0.05). At 12 weeks, 37 patients in group A had ACT score over 19, with 17 having high control level; 22 patients in group B had ACT score over 19, 4 showing high control level; the two groups were similar in the control levels (P>0.05) but showed significant difference in self-evaluation (Pevaluation (Peducation level may play a role in self-evaluation and control level of bronchial asthma, but its impact differs in the course of the treatment.

    The real life effectiveness, safety and the use of omalizumab for Portuguese patients with uncontrolled persistent allergic asthma are not sufficiently well known. The objective of this report was to make an evaluation, in a post-marketing, non-interventional, observational registry, of the Portuguese population included in the eXpeRience study. The methods used in this report are the same as the global eXpeRience ones, applied to a Portuguese sub-population. Patients with uncontrolled allergic asthma who had started omalizumab within the previous 15 weeks were enrolled and received omalizumab add-on therapy for 24 months. The physicians' global evaluation of treatment effectiveness (GETE), asthma symptoms and control (ACT score), quality of life (mini-AQLQ score), exacerbations, and serious adverse events (SAE) were reported. Of the 943 patients recruited in the eXpeRience registry, 62 patients were from Portugal. 62.1% of them were observed to be responders with good/excellent GETE assessment at Week 16. Clinically meaningful improvements in asthma control (ACT score) and quality of life (mini-AQLQ score) were observed with omalizumab therapy at Months 12 (mean change: +7.7 [n=35]; +2.1 [n=20], respectively) and 24 (mean change: +7.0 [n=26]; +2.7 [n=13], respectively). Asthma symptoms and rescue medication usage were reduced to ≤1 day/week at Month 24 from a baseline of ≥3.5 days/week. The proportion of patients with no clinically significant exacerbations increased from 6.5% during pre-treatment (n=62) to 50% at Month 12 (n=54) and 60% at Month 24 (n=45). The findings from the Portugal subpopulation of eXpeRience registry confirm that omalizumab add-on therapy is efficacious and well tolerated in the management of uncontrolled persistent allergic asthma. Another pertinent issue is the fact that the Portuguese subpopulation response is similar to the international population average of the study. Copyright © 2014 Sociedade Portuguesa de Pneumologia

    Full Text Available Abstract Background Asthma and COPD are major health problems and an extensive burden for the patient and the health care system. Patient education has been recommended, but the influence on knowledge and health outcomes is not fully examined. Our aims were to compare patient characteristics, education and knowledge in patients who had an emergency room (ER visit, to explore factors related to disease knowledge, and to investigate patient characteristics, patient education and knowledge in relation to further ER visits over a 12 month period. Methods Eighty-four patients with asthma and 52 with COPD, who had had an ER visit, were included. They were interviewed by telephone 4 to 6 weeks after the ER visit and followed for a year. Results Patients with COPD were older, more sedentary, had had more ER visits the previous year, and had more co morbidity than patients with asthma. About 80% of the patients had received information from health professionals or participated in education/rehabilitation, but a minority ( Conclusion Patients with asthma had a better self reported knowledge of disease management and were less likely to have new exacerbations than patients with COPD. Reported level of knowledge was, however, in it self not a predictor of exacerbations. This indicates that information is not sufficient to reduce the burden of disease. Patient education focused on self-management and behavioral change should be emphasized.

  10. Mechanical ventilation for severe asthma.

    Acute exacerbations of asthma can lead to respiratory failure requiring ventilatory assistance. Noninvasive ventilation may prevent the need for endotracheal intubation in selected patients. For patients who are intubated and undergo mechanical ventilation, a strategy that prioritizes avoidance of ventilator-related complications over correction of hypercapnia was first proposed 30 years ago and has become the preferred approach. Excessive pulmonary hyperinflation is a major cause of hypotension and barotrauma. An appreciation of the key determinants of hyperinflation is essential to rational ventilator management. Standard therapy for patients with asthma undergoing mechanical ventilation consists of inhaled bronchodilators, corticosteroids, and drugs used to facilitate controlled hypoventilation. Nonconventional interventions such as heliox, general anesthesia, bronchoscopy, and extracorporeal life support have also been advocated for patients with fulminant asthma but are rarely necessary. Immediate mortality for patients who are mechanically ventilated for acute severe asthma is very low and is often associated with out-of-hospital cardiorespiratory arrest before intubation. However, patients who have been intubated for severe asthma are at increased risk for death from subsequent exacerbations and must be managed accordingly in the outpatient setting.

    Full Text Available The efficacy of omalizumab has been extensively investigated in clinical trials in patients with severe persistent allergic (pre-treatment total immunoglobulin E 30–700 IU·mL–1 asthma including the Investigation of Omalizumab in Severe Asthma Treatment (INNOVATE study, which enrolled patients with inadequately controlled severe persistent allergic asthma despite receiving high-dose inhaled corticosteroid in combination with a long-acting beta2-agonist, and also additional controller medication if required. In the INNOVATE study, add-on omalizumab significantly reduced clinically significant exacerbation rates by 26% (0.68 versus 0.91, severe exacerbation rates by 50% (0.24 versus 0.48 and emergency visit rates by 44% (0.24 versus 0.43 and significantly improved asthma-related quality of life (QoL compared with placebo. In a pooled analysis of data from seven studies, add-on omalizumab significantly reduced asthma exacerbation rates by 38% (0.91 versus 1.47 and total emergency visits by 47% (0.332 versus 0.623. In addition, omalizumab significantly improved QoL versus current asthma therapy in a pooled analysis of data from six studies. Omalizumab has demonstrated a good safety and tolerability profile in completed phase-I, -II and -III studies involving >7,500 patients with asthma, rhinitis or related conditions. Omalizumab represents a major advance for the treatment of severe persistent allergic asthma that is inadequately controlled despite treatment with inhaled corticosteroids and a long-acting beta2-agonist.

    Full Text Available Background: According to the Global Initiative for Asthma (GINA, the levels of asthma symptom control can be divided into controlled, partially controlled and uncontrolled asthma. Optional therapy for non-steroidal anti-inflammatory drugs (NSAIDs-hypersensitive asthmatics uses aspirin desensitization, but until now, this therapy is not established in difficult to treat cases. The aim of this study was to evaluate the efficacy of aspirin desensitization in patients with poorly controlled asthma. Methods: Patients with poorly controlled asthma, NDAIDs hypersensitivity and aspirin desensitization were included in the retrospective study. The data were compared to those obtained from patients with controlled asthma and aspirin therapy. Lung function, levels of asthma symptom control, asthma medication, the size of nasal polyps (NP and smell function were evaluated over 18 months. Results: Thirty-two patients were included in the study (uncontrolled/partially controlled asthma n = 12; controlled asthma n = 20. After 18 months of follow-up, the patients with poorly controlled asthma had significantly increased forced expiratory volume in 1 s (FEV1 values, as compared to the baseline (66–82%; p = 0.02, the levels of asthma control improved significantly (p  0.05 and the asthma medication was constant. In relation to nasal parameters the sense of smell improved significantly in both groups, NP-scores did not differ significantly. Conclusions: Patients with a poorly controlled asthma and NSAIDs hypersensitivity profit from an add-on aspirin therapy.

    Full Text Available Background: The prevalence of asthma in adults varied from 0.96% to 11.03% while in children ranged from 2.3% to 11.9% in India. A number of factors including genetic predisposition, environment, and lifestyle factors including dietary habits influence the development and expression of asthma. The goal of asthma treatment is to achieve and maintain clinical control, which can be achieved in a majority of patients with pharmacologic intervention strategy. Objective: To assess the role of diet and lifestyle factors in asthma control in Indian population. Materials and Methods: Diagnosed asthma patients (aged 12-40 years were enrolled from the outpatient clinics. All patients were followed up and reassessed after 4 weeks with asthma control test (ACT and dietary and lifestyle questionnaire. The assessment of dietary pattern was performed by food frequency questionnaire (Nordic Nutrition Recommendations-Danish Physical Activity Questionnaire. The lifestyle factor included body mass index, smoking status, tobacco chewing, alcohol consumption, duration of travel (h/week, mental stress (visual analog scale: 0-10, sports activity - h/day, television (TV watching/video games - h/day, duration of sleep - h/day. Results: Seventy-five asthma patients (43 males and 32 females were divided into three groups according to ACT, 18 (24% patients in poorly-controlled asthma, 35 (46.7% in well-controlled asthma, and 22 (29.3% patients with totally-controlled asthma. Increased consumption of vegetables and cereals in patients with total-controlled asthma while increased consumption of sugar, nonvegetarian, fast food, salted and fried snacks in patients with poorly-controlled asthma. Poorly-controlled asthma had the highest duration of watching TV and sleep and least duration of travel and sports, though the results failed to reach statistical significance. Conclusion: The dietary and lifestyle factors too contribute to degree of control of asthma in India.

    The association between vitamin D and clinical parameters in obstructive lung diseases (OLDs), including COPD and bronchial asthma, was previously investigated. As asthma-COPD overlap syndrome (ACOS) is a new clinical entity, the prevalence of vitamin D levels in ACOS is unknown. Our aim was to assess the levels of circulating vitamin D (25-hydroxyvitamin D [25(OH)D]) in different OLDs, including ACOS patients, and its correlation with clinical parameters. A total of 106 men and women (control, n=21; asthma, n=44; COPD, n=21; and ACOS, n=20) were involved in the study. All patients underwent detailed clinical examinations; disease control and severity was assessed by disease-specific questionnaires (COPD assessment test, asthma control test, and modified Medical Research Council); furthermore, 25(OH)D levels were measured in all patients. The 25(OH)D level was significantly lower in ACOS and COPD groups compared to asthma group (16.86±1.79 ng/mL and 14.27±1.88 ng/mL vs 25.66±1.91 ng/mL). A positive correlation was found between 25(OH)D level and forced expiratory volume in 1 second (r=0.4433; PD level showed a positive correlation in the ACOS (r=0.4761; P=0.0339) but not in the asthma group. Higher COPD assessment test total scores correlated with decreased 25(OH)D in ACOS (r=-0.4446; P=0.0495); however, this was not observed in the COPD group. Vitamin D deficiency is present in ACOS patients and circulating 25(OH)D level may affect disease control and severity.

    In the present study, hospital costs of patients who admitted to the emergency department with asthma attack and several variables that could effect this cost were analyzed and data were collected in order to reduce economical burden of that disease was aimed. Between September 2005 and February 2007 patients with acute asthma attack, admitted to Pamukkale University Hospital Emergency Department were retrospectively evaluated. Totally 108 patients who met the inclusion criteria admitted to the emergency department with asthma acute attack. Of those 97 were women (89.8%). Forty mild, 51 moderate, 15 severe and 2 life-threatening attacks were detected. Severe and life-threatening attacks were more frequent in patients graduated from primary school compared with the other groups. Mean therapy costs of the patients who were hospitalized and treated in the emergency department were 836.60 +/- 324.30 TL (Turkish Lira) and 170.66 +/- 86.71 TL respectively. Treatment procedures consisted of 45.8% of and 38.5% hospital costs for patients treated in the emergency department and for patients hospitalized respectively. There was a statistically significant difference in the comparison of costs according to the attack severity (p= 0.0001). Education level of the patients had a significant effect on hospital costs (p= 0.025). Comorbidities were found a significant increasing factor of treatment costs (p= 0.017). There were no effects of sex, age, medical insurance or duration of asthma disease on the hospital costs. The relation between low-education level, living in the rural area and admissions with severe attacks of asthma to emergency department show the importance of treatment success with patient compliance. Positive and negative factors effecting disease control should be detected by evaluating larger populations to reduce economical burden of asthma.

    Although it is well established that family-centered education is critical to managing childhood asthma, the information needs of parents of children with asthma are not being met through current educational approaches. Patient-driven educational materials that leverage the power of the storytelling and the arts show promise in communicating health information and assisting in illness self-management. However, such arts-based knowledge translation approaches are in their infancy, and little is known about how to develop such tools for parents. This paper reports on the development of "My Asthma Diary" - an innovative knowledge translation tool based on rigorous research evidence and tailored to parents' asthma-related information needs. We used a multi-stage process to develop four eBook prototypes of "My Asthma Diary." We conducted formative research on parents' information needs and identified high quality research evidence on childhood asthma, and used these data to inform the development of the asthma eBooks. We established interdisciplinary consulting teams with health researchers, practitioners, and artists to help iteratively create the knowledge translation tools. We describe the iterative, transdisciplinary process of developing asthma eBooks which incorporates: (I) parents' preferences and information needs on childhood asthma, (II) quality evidence on childhood asthma and its management, and (III) the engaging and informative powers of storytelling and visual art as methods to communicate complex health information to parents. We identified four dominant methodological and procedural challenges encountered during this process: (I) working within an inter-disciplinary team, (II) quantity and ordering of information, (III) creating a composite narrative, and (IV) balancing actual and ideal management scenarios. We describe a replicable and rigorous multi-staged approach to developing a patient-driven, creative knowledge translation tool, which can be

    After the GINA 2006 publication, asthma therapy is based on control of symptoms. However there are suggestions of monitoring of airway inflammation. Aim of the study was to compare clinical criteria of asthma control with cellular markers of lower airway inflammation in induced sputum in a group of young asthmatics. To assess relationship between sputum eosinophilia, asthma severity and spirometry. A group of 154 young patients with chronic asthma (8-21 years) underwent sputum induction by inhalation of 4,5% saline solution. Sputum induction was effective in 121 patients (78%), and in this group control of clinical symptoms was assessed according to GINA 2006 criteria. Asthma was controlled in 82 subjects (67.8%) and uncontrolled in 39 (32.2%). Patients with controlled asthma had higher FEV1/FVC (79.8 +/- 7.1% vs 74.2 +/- 9.9%; p = 0.004) and MMEF (80.7 +/- 23.0% vs 65.3 +/- 21.8%; p 3%) was observed in 24.4% of patients with controlled asthma and in 61.5% with uncontrolled asthma (p astma than in patients with moderate-severe disease (3.1 +/- 5.7% vs 7.1% +/- 8.8; p = 0.006). Patients with high sputum eosinophil count had lower FEV1 (89.4 +/- 14.9% vs 94.9 +/- 13.9%; p = 0.047), FEV1/FVC (74.5 +/- 10.1% vs 79.2 +/- 9.3%; p = 0.01) and MMEF (68.7 +/- 23.3% vs 81.7 +/- 23.1%; p = 0.004). In this study of young asthmatics, control of asthma symptoms was observed in 67.8% of patients. However, cellular markers of lower airway inflammation were present in 1/4 of patients with controlled asthma and in 3/4 with uncontrolled disease. Sputum eosinophilia was related to asthma severity. FEV1/FVC and MMEF were more important that FEV1 for estimating control of asthma. Improvement of asthma control scoring is needed as well as availability of simple methods of inflammation monitoring.

    Studies have linked the use of inhaled corticosteroids (ICSs) to excess pneumonia risk in chronic obstructive pulmonary disease patients. The risk in asthma patients remains unclear. The objective of the present study was to examine the risk of pneumonia with ICSs in asthma patients aged 12-35 years. We formed a cohort of asthma patients treated from 1990 to 2007 using Quebec health insurance databases. Subjects were considered currently exposed if they had had an ICS dispensed within the 60 days prior to their pneumonia index event or matched person-moment. Secondary analyses investigated the risk of pneumonia according to ICS dose and type. Rate ratios (RRs) and rate differences (RDs) were both estimated through a quasi-cohort approach. The cohort included 152 412 subjects, of whom 1928 had a pneumonia event during follow-up. There was an increased risk of pneumonia associated with current use of ICSs [RR 1.83; 95% confidence interval (CI) 1.57, 2.14] or an excess risk of 1.44 cases per 1000 person-years (RD 1.44; 95% CI 1.03, 1.85). There was an excess pneumonia risk with low doses (RR 1.60; 95% CI 1.06, 2.45), moderate doses (RR 1.53; 95% CI 1.12, 2.08) and high doses (RR 1.96; 95% CI 1.64, 2.34) of ICSs, and with budesonide (RR 2.67; 95% CI 2.05, 3.49) and fluticasone (RR 1.93; 95% CI 1.58, 2.36), specifically relative to no use. When accounting for potential protopathic bias, the risk with current use of ICSs was attenuated (RR 1.48; 95% CI 1.22, 1.78). ICS use in asthma patients appears to be associated with an increased risk of pneumonia and is present for both budesonide and fluticasone. © 2017 The British Pharmacological Society.

    INTRODUCTION: Many patients with asthma seek alternative or adjunctive therapies. One such modality is reflexology. Our aim was to examine the popular claim that reflexology treatment benefits bronchial asthma. MATERIAL AND METHODS: Ten weeks of either active or simulated (placebo) reflexology were...... compared in an otherwise blind, controlled trial of 40 patients with asthma. RESULTS: Objective lung function tests did not change. Subjective scores and bronchial sensitivity to histamine improved on both regimens, but no differences were found in the groups receiving active or placebo reflexology....... However, a trend in favour of reflexology became significant when a supplementary analysis of symptom diaries was carried out. At the same time a significant pattern compatible with subconscious un-blinding was found. DISCUSSION: We found no evidence that reflexology has a specific effect on asthma beyond...

    Pulmonary diseases [asthma, chronic obstructive pulmonary disease (COPD), and tuberculosis (TB)] are associated with lung cancer mortality. However, the relationship between coexisting pulmonary diseases and survival in patients with lung squamous cell carcinoma (SqCC) has not been well defined. Patients newly diagnosed with SqCC between 2003 and 2008 were identified by linking the National Health Insurance Research Database and Taiwan Cancer Registry Database. Cases with SqCC were followed up until death, loss to follow-up, or study end in 2010. Information on health status, date of death and the main causes of death was ascertained from the National Death Registry Database. Cox proportional hazard regression was used to calculate the hazard ratio (HR) of coexisting asthma, COPD and/or TB. During the study period, a total of 5406 cases with SqCC were enrolled. For all cause-mortality, HRs were 1.08 [95% confidence interval (CI), 0.99-1.18], 1.04 (95% CI, 0.97-1.12), and 1.14 (95% CI, 1.00-1.31) for individuals with asthma, COPD, and TB, respectively. Specifically, among men with coexisting pulmonary diseases, the HRs were 1.56 (95% CI, 1.23-1.97) and 1.11 (95% CI, 1.00-1.24) for individuals with asthma+COPD+TB and asthma+COPD, respectively. Among male patients with stage III SqCC, HRs were 3.41 (95%CI, 1.27-9.17) and 1.65 (95%CI, 1.10-2.47) for individuals with asthma+TB and asthma+COPD+TB, respectively. Among male patients with stage IV SqCC, HRs were 1.40 (95%CI, 1.00-1.97) and 1.25 (95%CI, 1.03-1.52) for individuals with asthma+ COPD+TB and asthma. Among female patients with stage I and II, HR was 0.19 (95%CI, 005-0.77) for individuals with asthma. Coexisting pulmonary diseases increased the risk of mortality from SqCC in male patients. For female patients with early stage SqCC, pre-existing asthma decreased mortality. These patients deserve greater attention while undergoing cancer treatment.

    Conclusion: A high index of suspicion is warranted for the overlap of OSA and asthma, particularly in the presence of obesity, GERD, and in patients with severe asthma. Individualized therapy addressing these moderating factors is warranted for optimal health outcomes. Recognition and treatment of OSA in asthmatics is an important element in improving asthma control.

    Full Text Available In epidemiological studies, continuous measures of asthma severity should be used to catch the heterogeneity of phenotypes. This study aimed at developing and validating continuous measures of asthma severity in adult patients with ever asthma from the general population, to be used in epidemiological studies.Respiratory symptoms, anti-asthmatic treatment and lung function were measured on 520 patients with ever asthma aged 20-64 years from the general Italian population (GEIRD study; 2007/2010. The variables that represent the same dimension of asthma severity were identified through an exploratory factor analysis and were summarized through a multiple factor analysis.Only respiratory symptoms and anti-asthmatic treatment were summarized in a continuous score (STS. STS ranges from 0 (no symptoms/treatment to 10 (maximum symptom frequency and treatment intensity. STS was positively correlated with the Global Initiative for Asthma classification of asthma severity computed on the 137 cases with a doctor's diagnosis (Spearman's coefficient = 0.61, p-value<0.0001 (concurrent validity. Furthermore, using a cohort of 1,097 European asthmatics (ECRHS II study; 1999/2002, increasing STS levels at baseline (1991/1993 were positively associated with long-term outcomes (hospitalization and lost workdays for breathing problems, asthma attack frequency and use of asthma controllers (predictive validity. Finally, the STS scores computed from the GEIRD and ECRHS II data were comparable (Lin's coefficient = 0.95, p-value<0.0001 (replication analysis.STS is a valid and replicable measure of asthma severity in adults, which could be used in association studies.

  8. Examining the unmet need in adults with severe asthma

    Full Text Available Asthma currently affects an estimated 300 million people worldwide and the number is expected to rise to 400 million by 2025. Asthma morbidity remains high and the economic burden is significant. Approximately 20% of patients have severe persistent asthma. As patients with severe asthma often have a variety of conditions that may coexist with or be mistaken for asthma, careful diagnosis and management are essential, and adhering to a protocol for investigations is helpful. For patients with severe persistent asthma, the Global Initiative for Asthma 2005 guidelines recommend the use of high-dose inhaled corticosteroids in combination with a long-acting beta2-agonist, with one or more additional controller medications if required (step 4 therapy. However, recent studies have shown that asthma remains inadequately controlled in many patients with severe asthma, despite treatment in accordance with guidelines. Patients with severe asthma have the highest healthcare utilisation and mortality, and there is clearly an unmet need for the effective and safe treatment of patients with severe persistent allergic asthma who remain symptomatic despite optimised standard treatment. The latest guidelines suggest that omalizumab may address this unmet need.

    Churg-Strauss syndrome (CSS) is a rare multisystem vasculitis. Considering the variation of autoimmune diseases in different races, it is of interest to determine whether any outstanding features exist for Turkish patients with CSS. The aim of this study was to evaluate the clinical and serological features of the disease, the treatment, and long-term follow-up details, and to investigate possible etiological factors of Turkish CSS patients. The study included 14 patients who were diagnosed with CSS, and followed by our department between 2004 and 2012. Possible etiological factors, initial symptoms, clinical presentations, treatment, as well as outcomes were documented. The study was approved by the local ethics. All patients fulfilled the American College of Rheumatology criteria. Initial symptoms were worsening asthma (n = 14; 100%) and skin lesions (n = 6; 43%). All patients had a diagnosis of asthma and nasal polyps, whereas 57.1% had aspirin hypersensitivity at the time of diagnosis. The lungs (100%) and skin (43%) were most commonly involved. Peripheral eosinophilia dominated on initial presentations of all patients. Initial treatments included oral methyl prednisolone in all cases, whereas cyclophosphamide and azathioprine were used in three cases. Relapses were detected in five cases. None of the cases were able to stop the oral corticosteroid treatment. No fatalities were observed. We herein describe a new severe asthma endotype in connection with CSS. We suggest that physicians who deal with uncontrolled severe asthma cases should consider CSS in the presence of nasal polyps, aspirin hypersensitivity, and especially peripheral blood eosinophilia over 10%. © 2014 John Wiley & Sons Ltd.

    Full Text Available Nicola Scichilone, Salvatore Battaglia, Alida Benfante, Vincenzo BelliaDipartimento Biomedico di Medicina Interna e Specialistica, University of Palermo, Palermo, ItalyAbstract: Asthma is a disease of all ages. This assumption has been challenged in the past, because of several cultural and scientific biases. A large body of evidence has accumulated in recent years to confirm that the prevalence of asthma in the most advanced ages is similar to that in younger ages. Asthma in the elderly may show similar functional and clinical characteristics to that occurring in young adults, although the frequent coexistence of comorbid conditions in older patients, together with age-associated changes in the human lung, may lead to more severe forms of the disease. Management of asthma in the elderly follows specific guidelines that apply to all ages, although most behaviors are pure extrapolation of what has been tested in young ages. In fact, age has always represented an exclusion criterion for eligibility to clinical trials. This review focuses specifically on the safety and efficacy of leukotriene modifiers, which represent a valid option in the treatment of allergic asthma, both as an alternative to first-line drugs and as add-on treatment to inhaled corticosteroids. Available studies specifically addressing the role of montelukast in the elderly are scarce; however, leukotriene modifiers have been demonstrated to be safe in this age group, even though cases of acute hepatitis and occurrence of Churg-Strauss syndrome have been described in elderly patients; whether this is associated with age is to be confirmed. Furthermore, leukotriene modifiers provide additional benefit when added to regular maintenance therapy, not differently from young asthmatics. In elderly patients, the simpler route of administration of leukotriene modifiers, compared with the inhaled agents, could represent a more effective strategy in improving the outcomes of asthma therapy

  12. Severe asthma in childhood

    Patients with severe asthma are clinically, physiologically and biologically a heterogeneous group. About half of children referred for medical examination for severe asthma have true severe, therapy resistant asthma. The rest of referred patients have difficult to treat asthma. Symptoms persist mostly due to drug non-compliance, inappropriate inhalation technique, persistent environmental exposures or co-morbid conditions. Compared with adults have children more frequently atopic form of severe asthma. This is associated with eosinophilia in peripheral blood and sensitization to inhaled allergens. The IgE levels are high. Therapy of co-morbidities and improvement of treatment compliance lead in most cases to full asthma control. Proportion of children will benefit from biologics like anti-IgE monoclonal antibody, administered by subcutaneous injections in 2 to 4 week intervals. By this therapy it is not only possible to suppress symptoms, but also decrease the total steroid dose and the risk of adverse effects associated with its long-term administration. By achieving a full asthma control we lower future risk of exacerbations and probably improve long-term prognosis of disease, frequently persisting for the rest of life. (author)

    Goal setting is recommended in UK health policy to make health care more patient-centred, to enhance the likelihood of behaviour change and to improve health outcomes. Patient-centred care is thought to be particularly important in the management of long term conditions such as asthma. We therefore explored and compared the asthma goals of both health professionals and people with asthma within the primary care clinical consultation, and identified the potential barriers to achieving shared goals and more patient-centred care provision. We conducted a qualitative study based on semi-structured interviews with 15 people with asthma, 7 general practitioners and 6 primary care asthma nurses from Tayside, UK. The data were analysed using the 'Framework' methodology. Four potential barriers to the identification of goals were located. The first stemmed from the status and nature of patients' goals, while the remaining three related to the beliefs and practices of health professionals. These findings are discussed in relation to relevant sociological literature around the potential tensions between lay and professional knowledge, and also tensions in the relationship between knowledge and values. We conclude that barriers need to be recognised and addressed where possible before the achievement of shared asthma goals can become common practice. In particular, health professionals may require training in how to elicit goals with patients and how to differentiate between end states and goals that are in fact assumed to mediate the achievement of such desired end states.

    Migraine and asthma are comorbid chronic disorders with episodic attacks thought to involve inflammatory and neurological mechanisms. The objective of the present study is to investigate the relationship of asthma features between the asthma patients with migraine and those without migraine headache. A cross-sectional study was conducted from October 2015 to June 2016. Physician-diagnosed asthma patients aged 18 years and above were included. Demographic data, pulmonary function test and treatment of asthma were recorded. Asthma control was assessed using the asthma control test (ACT) and asthma control questionnaire (ACQ). The diagnosis of migraine was made by the neurologist with face-to face examinations based on the International Classification of Headache Disorders, third edition beta (ICHD-III-beta) criteria. Data about the age at onset, frequency of headache attacks, duration of headache attack, the presence of aura, and severity of headache were recorded. The severity of headache was evaluated using visual analogue scale (VAS). Overall 121 asthma patients were included in this study. Migraine was found to be present in 32 (26.4%) of patients. No statistically significant difference was found between asthma group and asthma with migraine groups in terms of pulmonary function test parameters. The mean ACT score in asthma with migraine patients group was significantly lower than the asthma groups. Morever, in the group asthma with migraine, a negative significant correlations were found between ACT scores with VAS scores. This study demonstrates that migraine headache may be associated with poor asthma control. On the other hand, it should not be forgotten that ACT is a subjective test and can be affected from by many clinical parameters.

    It is well recognized that atopic sensitization is an important risk factor for asthma, both in adults and in children. However, the role of allergy in severe asthma is still under debate. The term 'Severe Asthma' encompasses a highly heterogeneous group of patients who require treatment on steps 4-5 of GINA guidelines to prevent their asthma from becoming 'uncontrolled', or whose disease remains 'uncontrolled' despite this therapy. Epidemiological studies on emergency room visits and hospital admissions for asthma suggest the important role of allergy in asthma exacerbations. In addition, allergic asthma in childhood is often associated with severe asthma in adulthood. A strong association exists between asthma exacerbations and respiratory viral infections, and interaction between viruses and allergy further increases the risk of asthma exacerbations. Furthermore, fungal allergy has been shown to play an important role in severe asthma. Other contributing factors include smoking, pollution and work-related exposures. The 'Allergy and Asthma Severity' EAACI Task Force examined the current evidence and produced this position document on the role of allergy in severe asthma. © 2016 John Wiley & Sons A/S.

    Asthma requires individually tailored and careful management to control and prevent symptoms and exacerbations. Selection of the most appropriate treatment is dependent on both the choice of drugs and inhaler device; however, financial pressures may result in patients being switched to alternative medications and devices in an attempt to reduce costs. This review aimed to examine the published literature in order to ascertain whether switching a patient's asthma medications or device negatively impacts clinical and economic outcomes. A literature search of MEDLINE (2001-13 September 2011) was conducted to identify English-language articles focused on the direct impact of switching medications and inhaler devices and switching from fixed-dose combination to monocomponent therapy via separate inhalers in patients with asthma; the indirect impacts of switching were also assessed. Evidence showed that non-consented switching of medications and inhalers in patients with asthma can be associated with a range of negative outcomes, at both individual and organisational levels. Factors that reduce adherence may lead to compromised symptom control resulting in increased healthcare resource utilisation and poorer patient quality of life. The consequences of a non-consented switch should be weighed carefully against arguments supporting an inhaler switch without the patient's consent for non-medical/budgetary reasons, such as potential reductions in initial acquisition costs, which may be associated with subsequent additional healthcare needs. Given the increasing pressure for reduced costs and efficient allocation of limited healthcare resources, an additional investment in ensuring high medication adherence may lead to greater savings due to a potentially decreased demand for healthcare services. In contrast, savings achieved in acquisition costs may result in a greater net loss due to increased healthcare consumption caused by decreased asthma control. © 2013 The Authors

    Pulmonary hemodynamic disorders depend on the inflammatory phases and severity of the obstructive syndrome. However, the effect of asthma bronchial obstruction on the state of peripheral hemodynamics remains insufficiently known. To study the effects of airway obstruction on skin blood flow parameters and its regulatory systems in patients with persistent atopic bronchial asthma in the remission state. A comparative study of the skin peripheral blood flow in patients with bronchial asthma with severe airway obstruction (1st group) and without obstruction (2nd group) was conducted. 20 patients with confirmed diagnosis of atopic asthma of 50–74 years old participated in the study. All patients received basic therapy in a constant dosing of high doses of inhaled glucocorticosteroids/long-acting beta-2-agonists. The control group included 20 healthy volunteers without evidence of bronchial obstruction. The study lasted for 3 months. The forced expiratory volume in 1 s (FEV1) was used to evaluate the bronchial obstruction by spirometry technique. Skin blood perfusion changes were recorded by laser Doppler flowmetry at rest and in response to short-term local ischemia. Registered peripheral blood flow signals were examined using the amplitude temporal filtering in five frequency intervals to identify the functional features of the peripheral blood flow regulation systems. Consistent two-fold decrease of the oscillation amplitudes was found in the neurogenic interval at rest (p=0.031), as well as in the myogenic (p=0.043; p=0.031) and endothelial intervals (p=0.037; p≤0.001) both at rest and during the postocclusive reactive hyperemia respectively in the 1st group of patients with bronchial obstruction (FEV1 obstruction, FEV1 >80%) in comparison to control subjects. The presence of bronchial obstruction has a significant impact on the changes of the amplitudes of skin blood flow oscillations in patients with bronchial asthma in the myogenic, neurogenic and endothelial

    Objective: To investigate the clinical significance of changes of serum TNF, IL-8 and GM-CSF in pediatric patients with bronchial asthma. Methods: Serum TNF, IL-8 and GM-CSF levels were measured with RIA in 32 pediatric patients with bronchial asthma and 30 controls. Results: Serum levels of TNF, IL-8 and GM-CSF were very significantly higher in pediatric patients with bronchial asthma than those in controls (P<0.01). After one week treatment, the levels dropped considerably but still remained significantly higher than those in controls (P<0.05). Conclusion: These cytokines participated in the pathogenesis of bronchial asthma. Monitoring the changes of their serum levels was helpful for the management of the diseases. (authors)

    To examine the concordance between spirometry and asthma symptoms in assessing asthma severity and beginning therapy by the general pediatrician. Between 2008 and 2012, spirometry testing was satisfactorily performed in 894 children (ages 5-19 years) whose asthma severity had been determined by their pediatrician using asthma guideline-based clinical criteria. Spirometry-determined asthma severity using national asthma guidelines and clinician-determined asthma severity were compared for concordance using weighted Kappa coefficients. Thirty percent of participants had clinically determined intermittent asthma; 32%, 33%, and 5% had mild, moderate, and severe, persistent asthma, respectively. Increasing disease severity was associated with decreases in the forced expiratory volume in 1 second/forced vital capacity (FVC) ratio (P spirometry-determined severity. Concordance was 0.16 (95% CI 0.10, 0.23), and when adjusted for bias and prevalence, was 0.20 (95% CI 0.17, 0.23). When accounting for age, sex, exposure to smoke, and insurance type, only spirometry-determined asthma severity was a significant predictor of agreement (P spirometry-determined severity increased. Concordance between spirometry and asthma symptoms in determining asthma severity is low even when guideline-based clinical assessment tools are used. Because appropriate therapy reduces asthma morbidity and is guided by disease severity, results from spirometry testing could better guide pediatricians in determining appropriate therapy for their patients with asthma.

    This cross sectional descriptive study was conducted among the chronic asthma patients attending three Institutes of Dhaka city namely National Asthma Center, The National Institute of Diseases of Chest and Hospital (NIDCH), Mohakhali, and Dhaka Medical College Hospital to assess the level of knowledge regarding inhaler use. Convenient sampling was adopted. Data were collected using one semi-structured questionnaire through face-to-face interview. The patients were aged from 18 to 75 years with mean age being 40.68 years and sd +/- 11.659 years. The mean monthly income of the respondents found was 8278.52 taka with standard deviation +/- 3523.315 taka. Mean duration of bronchial asthma was 9.44 years with sd +/- 4.862 years. Out of the total 298 respondents 103(35.8%) possessed "excellent knowledge" on inhalers. Ninety one (31.6%) had "adequate knowledge", sixty nine (24.0%) had "poor knowledge" and thirty five (8.7%) respondents were found having "no knowledge" about inhalers. Males were seen having better knowledge than the females (chi2 =66.582, df=3, pknowledge than those from the outdoors (pLevel of Knowledge was also found to be associated with the educational status of the respondents. Respondents with higher education possessed more than the respondents with lower education (p<0.001). Though most of the physicians now prescribe inhalers, but many of them do not explain the proper use of inhaler. This may be corrected through training and motivation of physicians at Medical Colleges and Hospitals and during various medical conferences and other programs. To reduce the extent of suffering and economic burden of asthma patients and their families, active education program for the patients and training program for the health care providers, regarding "inhaler use technique" demands early consideration.

    Studies have reported an association between asthma and oral diseases, including periodontal diseases. The aim of this retrospective study is to investigate risk of periodontal diseases for patients with asthma. Using the claims data of National Health Insurance of Taiwan and patients without a history of periodontal diseases, 19,206 asthmatic patients, who were newly diagnosed from 2000 through 2010, were identified. For each case, four comparison individuals without history of asthma and periodontal disease were randomly selected from the general population and frequency matched (categorical matched) by sex, age, and year of diagnosis (n = 76,824). Both cohorts were followed to the end of 2011 to monitor occurrence of periodontal diseases. Adjusted hazard ratios (aHRs) of periodontal disease were estimated using Cox proportional hazards regression analysis. Overall incidence of periodontal diseases was 1.18-fold greater in the asthma cohort than in the comparison cohort (P periodontal diseases compared with those with a mean of less than one visit. Patients with at least three admissions annually also had a similar aHR (51.8) for periodontal disease. In addition, asthmatic patients on inhaled corticosteroid (ICS) therapy had greater aHRs than non-users (aHR = 1.12; 95% CI = 1.03 to 1.23). In the studied population, asthmatic patients are at an elevated risk of developing periodontal diseases. The risk is much greater for those with emergency medical demands or hospital admissions and those on ICS treatment.

    Despite the growing market of e-health disease self-management tools, few studies have reported the presence of teen patients in all phases of product design. While rates of American teens using mobile Internet grow, an opportunity to deliver disease self-management targeted for teen patients exists. Building on findings from previous investigations with teens with asthma, we explored teens' insights on the development of a patient-centered asthma management application (app). Two existing asthma apps were used by 16 teen asthmatics for 7-10 days. At the end of the trial period, in-depth interviews were conducted with each participant to gather insights about the user experience. Participants requested more asthma-related content that educates them about their condition. Suggested improvements to currently available apps included a longer list of selectable symptoms to track, medication tracking, and more compelling interface features. Participants showed interest in using apps for managing their asthma, yet recommended improvements on current design. Whereas national figures point to a more ubiquitous mobile device environment, implementation efforts must respond to participants' recommendations while minding lingering digital divides. Currently available apps lack appealing components that teens seek or desire. Subsequent development should include teens' participation in component design insights.

    Chlamydia pneumoniae is one of the most frequent pathogens causing airways infections. Contribution of chronic chlamydial infection to the following diseases: asthma, POChP, coronary heart disease, abdominal aortic aneurysm, is particularly interesting. The connection between such infection and bronchial asthma was described in the literature in 1991. C. pneumoniae often causes asthma exacerbation; it is suggested that it also may be an etiologic factor of the disease. In a group of 55 subjects with chronic, stable bronchial asthma treated in the Pulmonary Department, serologic characteristic of C. pneumoniae infection was found in 34 patients (61,8%). Thirteen of these subjects agreed to participate in the study. They were divided into two groups; placebo was administered to the first one and azithromycin in a dose of 1000 mg once a week--to the other one. The research was conducted using the double blind trial method. Anti-chlamydial antibody level was evaluated before and after treatment. Spirometry tests as well as subjective estimation of physical fitness and dyspnoea degree were also determined. In comparison with 'the placebo group', statistically significant improvement in respiratory parameters 'in the treated group' was not ascertained.

    Cysteinyl-leukotrienes (CysLTs; LTC4, LTD4, and LTE4) play a considerable role in the pathophysiology of aspirin-intolerant asthma (AIA). Saliva has recently been validated as novel, simple, and noninvasive method for investigating inflammation in patients with asthma. The aim of this study is to clarify the molecular species of CysLT in saliva and to evaluate the CysLT and LTB4 concentrations in saliva in AIA patients. We also examined how the CysLT concentration in saliva reflects that of their corresponding urinary metabolite. We preformed an analytical cross-sectional study. CysLT and LTB4 concentrations in saliva were quantified by enzyme immunoassay (EIA) following purification by high-performance liquid chromatography (HPLC). 1. When analyzed by EIA in combination with HPLC, saliva was found to consist of LTC4, LTD4 and LTE4 in similar amounts. 2. In saliva analysis among the three groups (AIA patients, aspirin-tolerant asthma [ATA] patients, and healthy subjects), both the concentrations of CysLTs and LTB4 were significantly higher in AIA patients than in ATA patients and healthy subjects. 3. We found significant correlations between CysLT concentration and LTB4 concentration in saliva in each group. 4. No significant correlation was found between the concentration of LTE4 in urine and that of CysLTs in saliva. In this study, we found higher concentrations of CysLTs and LTB4 in saliva from AIA patients than in saliva from ATA patients, suggesting that the quantification of CysLT and LTB4 concentrations in saliva may be another diagnostic strategy for AIA.

    Full Text Available Asthma results from a combination of three essential features: airflow obstruction, hyperresponsiveness of airways to endogenous or exogenous stimuli and inflammation. Inadequacy of the techniques to use different inhalation devices is one of the causes of therapeutic failure. The main purpose of this study was to evaluate how 20 medical students, 36 resident physicians of Internal Medicine/Pediatrics, and 40 asthma patients used three devices for inhalation therapy containing placebo. All patients were followed at the Pulmonary Outpatient Service of Botucatu Medical School and had been using inhaled medication for at least six months. The following devices were evaluated: metered dose inhalers (MDI, dry powder inhalers (DPI, and MDI attached to a spacer device. A single observer applied a protocol containing the main steps necessary to obtain a good inhaler technique to follow and grade the use of different devices. Health care professionals tested all three devices and patients tested only the device being used on their management. MDI was the device best known by doctors and patients. MDI use was associated with errors related to the coordination between inspiration and device activation. Failure to exhale completely before inhalation of the powder was the most frequent error observed with DPI use. In summary, patients did not receive precise instruction on how to use inhaled medication and health care professionals were not well prepared to adequately teach their patients.

    The aims of this survey were (1) to assess the quality of asthma treatment and control in Latin America, (2) to determine how closely asthma management guidelines are being followed, and (3) to assess perception, knowledge and attitudes related to asthma in Latin America. We surveyed a household sample of 2,184 adults or parents of children with asthma in 2003 in 11 countries in Latin America. Respondents were asked about healthcare utilization, symptom severity, activity limitations and medication use. Daytime asthma symptoms were reported by 56% of the respondents, and 51% reported being awakened by their asthma at night. More than half of those surveyed had been hospitalized, attended a hospital emergency service or made unscheduled emergency visits to other healthcare facilities for asthma during the previous year. Patient perception of asthma control did not match symptom severity, even in patients with severe persistent asthma, 44.7% of whom regarded their disease as being well or completely controlled. Only 2.4% (2.3% adults and 2.6% children) met all criteria for asthma control. Although 37% reported treatment with prescription medications, only 6% were using inhaled corticosteroids. Most adults (79%) and children (68%) in this survey reported that asthma symptoms limited their activities. Absence from school and work was reported by 58% of the children and 31% of adults, respectively. Asthma control in Latin America falls short of goals in international guidelines, and in many aspects asthma care and control in Latin America suffer from the same shortcomings as in other areas of the world.

    CT scans were obtained in 45 patients with bronchial asthma including 23 patients during asthmatic attack. CT findings were as follows. 1) In all cases, thickening of bronchial wall throughout from central to peripheral bronchi and without tapering and/or slight swelling of bronchovascular bundles were observed. 2) Characteristics findings in 23 patients with asthmatic attack, lobular and multilobular high attenuation area were observed in 17 patients (74%) and nonhomogeneous attenuation in lung fields were noticed in 13 patients (57%). 3) Multiple centrilobular sized high attenuation area were observed in 23 patients, but it was difficult to differenciation whether these findings were due to tiny nodules or to small vessels. In conclusion, further studies are needed to know which pathomorphological and/or pathophysiological conditions are underlying these CT findings. (author)

    2016-01-01

    The term asthma encompasses a disease spectrum with mild to very severe disease phenotypes whose traditional common characteristic is reversible airflow limitation. Unlike milder disease, severe asthma is poorly controlled by the current standard of care. Ongoing studies using advanced molecular and immunological tools along with improved clinical classification show that severe asthma does not identify a specific patient phenotype, but rather includes patients with constant medical needs, whose pathobiologic and clinical characteristics vary widely. Accordingly, in recent clinical trials, therapies guided by specific patient characteristics have had better outcomes than previous therapies directed to any subject with a diagnosis of severe asthma. However, there are still significant gaps in our understanding of the full scope of this disease that hinder the development of effective treatments for all severe asthmatics. In this Review, we discuss our current state of knowledge regarding severe asthma, highlighting different molecular and immunological pathways that can be targeted for future therapeutic development.

    Full Text Available Foreign body aspiration is an urgent condition that requires immediate diagnosis and intervention. It is generally seen in children and in elderly patients with neurological problems and rarely seen in healthy adults. There may be some clinical signs and symptoms in patients with foreign body aspiration from mild to severe; such as cough, shortness of breath and respiratory arrest. A 52-year-old woman applied to our clinic with the complaints of cough and shortness of breath, and she was misdiagnosed and treated as asthma for three months. The chest radiograph showed heterogenous opacity in the right paracardiac region, computerized tomography revealed the foreign body aspiration in right main bronchus and peripheric pneumonia. Flexible bronchoscopy examination was processed and the foreign body was excluded safely with the aim of crocodile forceps. Foreign body aspiration should be kept in the mind in a adult patient with a sudden onset of asthma like disorder.

    Full Text Available Background & aim: In recent decades, the use of media education to control the problems of patients with chronic diseases has been taken into consideration by medical staff, but few studies have been done on their effectiveness in improving the quality of sleep in patients with bronchial asthma. The aim of this study was to determine the effect of film-based education on sleep quality in patients with bronchial asthma.   Methods: The present study was a quasi-experimental study and all of the patients with bronchial asthma referred to the Asthma clinic of Boroujen were included in this study. Fifty one patients who were eligible for inclusion in the study were selected by non probability sampling method. The samples were assigned to randomly assigned blocks between the two test and control groups. For patients in the test group, patient education was performed through a 15-minute video clip by computer, DVD player and mobile phone, but patients in the control group only received routine care. The Pittsburgh Sleep Quality Index questionnaire was used to collect data one week before intervention and one month after intervention. The collected data were analyzed by descriptive statistics and t-test, Chi-square, Mann-Whitney and Wilcoxon tests.   Results: There was no significant difference before the intervention, in the overall score of sleep quality and its dimensions in the two groups (p = 0.66. There was a significant difference between the two groups after the intervention in the general score of sleep quality and the dimensions of sleep quality, sleep disturbances and sleep latency (p = 0.001 However, there was no significant difference in the use of sleep apnea, sleep duration, adequacy of sleep and daily dysfunction in the test and control groups.   Conclusion: The movie-based instruction has been able to improve the quality of sleep in patients with bronchial asthma. Considering the ease of implementation of this educational method

    Full Text Available Introduction: The coexistence of asthma and chronic rhinosinusitis (CRS is more common than expected given their individual prevalence in the general population and may affect patient’s quality of life. The aim of this study was to evaluate the prevalence of asthma in chronic rhinosinusitis in Mashhad, Northeast Iran.  Materials and Methods: This study was performed in two university hospital from November 2012 for 12 months. In total, 153 patients with chronic rhinosinusitis were enrolled and referred to a particular pulmonologist for asthma evaluation.  Results: The mean age of participants was 40.54±13.11 years, and 41.8% were male. In total, 63.4% of patients had the polypoid form of CRS. The proportion of patients in this study with asthma was 41.8%, compared with a general asthma prevalence in this region of 13.5%.  Conclusion: There is a high prevalence of asthma among patients with CRS, but it often remains undiagnosed. Asthma in CRS patients should be diagnosed and treated in order to improve patient’s quality of life. We recommend an evaluation of the lower airways in all of these patients as well as further studies in this field.

    Fractional exhaled nitric oxide (FeNO) is an easy, sensitive, reproducible, and noninvasive marker of eosinophilic airway inflammation. Accordingly, FeNO is extensively used to diagnose and manage asthma. Patients with COPD who share some of the features of asthma have a condition called asthma-COPD overlap syndrome (ACOS). The feasibility of using FeNO to differentiate ACOS patients from asthma and COPD patients remains unclear. From February 2013 to May 2016, patients suspected with asthma and COPD through physician's opinion were subjected to FeNO measurement, pulmonary function test (PFT), and bronchial hyperresponsiveness or bronchodilator test. Patients were divided into asthma alone group, COPD alone group, and ACOS group according to a clinical history, PFT values, and bronchial hyperresponsiveness or bronchodilator test. Receiver operating characteristic (ROC) curves were obtained to elucidate the clinical functions of FeNO in diagnosing ACOS. The optimal operating point was also determined. A total of 689 patients were enrolled in this study: 500 had asthma, 132 had COPD, and 57 had ACOS. The FeNO value in patients with ACOS was 27 (21.5) parts per billion (ppb; median [interquartile range]), which was significantly higher than that in the COPD group (18 [11] ppb). The area under the ROC curve was estimated to be 0.783 for FeNO. Results also revealed an optimal cutoff value of >22.5 ppb FeNO for differentiating ACOS from COPD patients (sensitivity 70%, specificity 75%). FeNO measurement is an easy, noninvasive, and sensitive method for differentiating ACOS from COPD. This technique is a new perspective for the management of COPD patients.

    Purpose of review Patient response to the asthma drug classes, bronchodilators, inhaled corticosteroids and leukotriene modifiers, are characterized by a large degree of heterogeneity, which is attributable in part to genetic variation. Herein, we review and update the pharmacogenetics and pharmaogenomics of common asthma drugs. Recent findings Early studies suggest that bronchodilator reversibility and asthma worsening in patients on continuous short-acting and long-acting β-agonists are related to the Gly16Arg genotype for the ADRB2. More recent studies including genome-wide association studies implicate variants in other genes contribute to bronchodilator response heterogeneity and fail to replicate asthma worsening associated with continuous β-agonist use. Genetic determinants of the safety of long-acting β-agonist require further study. Variants in CRHR1, TBX21, and FCER2 contribute to variability in response for lung function, airways responsiveness, and exacerbations in patients taking inhaled corticosteroids. Variants in ALOX5, LTA4H, LTC4S, ABCC1, CYSLTR2, and SLCO2B1 contribute to variability in response to leukotriene modifiers. Summary Identification of novel variants that contribute to response heterogeneity supports future studies of single nucleotide polymorphism discovery and include gene expression and genome-wide association studies. Statistical models that predict the genomics of response to asthma drugs will complement single nucleotide polymorphism discovery in moving toward personalized medicine. PMID:19077707

    Psoriasis and asthma are disorders driven by inflammation. Psoriasis may carry an increased risk of asthma, but the reverse relationship has not been investigated. To investigate the risk of psoriasis in subjects with childhood asthma in a nationwide Danish cohort. Data on all Danish individuals aged 6-14 years at study entry between 1 January 1997 and 31 December 2011 (n = 1,478,110) were linked at an individual level in nationwide registers. Incidence rates per 10,000 person-years were calculated, and incidence rate ratios (IRRs) adjusted for age, sex, concomitant medication and comorbidity were estimated by Poisson regression models. There were 21,725 cases of childhood asthma and 6586 incident cases of psoriasis. There were 5697 and 889 incident cases of mild and severe psoriasis, respectively. The incidence rates of overall, mild and severe psoriasis were 4.49, 3.88 and 0.61 for the reference population, and 5.95, 5.18 and 0.83 for subjects with childhood asthma, respectively. The IRRs for overall, mild and severe psoriasis were 3.94 [95% confidence interval (CI) 2.16-7.17], 5.03 (95% CI 2.48-10.21) and 2.27 (95% CI 0.61-8.42) for patients with childhood asthma. Childhood asthma was associated with a significantly increased risk of psoriasis. Further studies are warranted to determine the clinical significance and effects of therapeutic interventions on this association. © 2015 British Association of Dermatologists.

    With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient-clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. Mobile texting messaging has the potential to play an important role in patient-clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication.

However, asthma severity and location of airway obstruction have not been compared between asthmatic patients with and without evidence for remote mycoplasma infection.Objectives: The aim of this research was to study the relationship between previous M. pneumoniae infections in asthmatic patients and presence of any predilection for the involvement of central or peripheral airways, the severity of the disease, and asthma control.Methods: Sixty-two patients with asthma were assessed by a validated asthma control test (ACT. All patients underwent spirometry and lung volume studies by body plethysmography. The forced expiratory volume in 1 second (FEV1, forced vital capacity (FVC, total lung capacity (TLC, residual volume (RV, and functional residual capacity (FRC were measured. An oropharyngeal swab was obtained for polymerase chain reaction analysis to detect the mycoplasma antigen. Moreover, blood samples were obtained to measure the titration of antimycoplasma immunoglobulin M (IgM and IgG antibodies. The asthmatic patients with a positive IgG for mycoplasma and negative PCR and negative IgM antibody were considered to have remote history of mycoplasma infection. The relationship between the asthma control using ACT score and pulmonary function variables were compared in patients with and without evidence for remote mycoplasma infection.Results: The incidence of postnasal drip was higher among the patients with asthma who had no evidence for remote mycoplasma infection (61.3% vs 32%, P = 0.035.

    The management of the patient with pulmonary hypertension is a challenge for the anesthesiologists because the risk of right-sided heart failure is markedly increased. We experienced a case of general anesthesia for a patient with pulmonary hypertension (mean pulmonary arterial pressure 39 mmHg), bronchial asthma and obesity. A 31-year-old woman was scheduled for arytenoid rotation for left recurrent nerve palsy. We applied routine monitors (noninvasive blood-pressure, five-lead electrocardiogram, pulse oximeter), and direct blood pressure monitoring through the radial artery. Anesthesia was induced with midazolam 4 mg, fentanyl 100 microg and sevoflurane 5%, and maintained with sevoflurane (1-2%) and nitrous oxide in oxygen. Surgery was completed in 100 minutes without any complications. We could successfully perform general anesthesia in a patient complicated by pulmonary hypertension, bronchial asthma and obesity, without invasive right-sided heart catheterization.

    Control and severity of asthma are two different but complementary concepts. The severity of asthma could influence the control over time. The aim of this study was to demonstrate this relationship. A total 365 patients with persistent asthma (severity) were enrolled and followed-up prospectively. Data were analysed using a continuous time homogeneous Markov model of the natural history of asthma. Control of asthma was defined according to three health states which were qualified: optimal, suboptimal and unacceptable control (states 1, 2 and 3). Transition forces (denoted lambda(ij) from state i to state j) and transition probabilities between control states were assessed and the results stratified by asthma severity were compared. Models were validated by comparing expected and observed numbers of patients in the different states. Transition probabilities stabilised between 100-250 days and more rapidly in patients with mild-to-moderate asthma. Patients with mild-to-moderate asthma in suboptimal or unacceptable control had a high probability of transition directly to optimal control. Patients with severe asthma had a tendency to remain in unacceptable control. A Markov model is a useful tool to model the control of asthma over time. Severity modified clearly the health states. It could be used to compare the performance of different approaches to asthma management.

    We performed post hoc analyses to evaluate the effect of humanized monoclonal antibody mepolizumab in patients with severe eosinophilic asthma previously treated with omalizumab. Data were collected from two randomized double-blind, placebo-controlled studies: MENSA (NCT01691521: 32-week treatment phase) and SIRIUS (NCT01691508: 24-week treatment phase). Active treatment was 75 mg intravenous mepolizumab (MENSA) or 100 mg subcutaneous mepolizumab (MENSA, SIRIUS). Patients had evidence of eosinophilic inflammation ≥150 cells/μl (at screening) or ≥300 cells/μl (during the previous year). Primary outcomes were the rate of exacerbations (MENSA) and the percentage reduction in oral corticosteroid (OCS) dose (SIRIUS). Other outcomes included lung function (forced expiratory volume in 1 s and morning peak expiratory flow), Asthma Control Questionnaire (ACQ-5), St George's Respiratory Questionnaire (SGRQ) scores, and safety. Overall, 576 patients were included from MENSA and 135 from SIRIUS, with 13% and 33% previously receiving omalizumab, respectively. In MENSA, mepolizumab reduced the rate of exacerbations by 57% (prior omalizumab) and 47% (no prior omalizumab) vs placebo. In SIRIUS, reductions in OCS use were comparable regardless of prior omalizumab use. Despite reducing chronic OCS use, mepolizumab also resulted in similar reductions in exacerbation rate relative to placebo in both subgroups. Asthma control and quality of life improved with mepolizumab vs placebo in both studies independent of prior omalizumab use, as shown by ACQ-5 and SGRQ scores. Adverse events were also comparable irrespective of prior omalizumab use. These post hoc analyses indicate that patients with severe eosinophilic asthma respond positively to mepolizumab regardless of prior use of omalizumab. © 2016 The Authors.

    We investigated whether asthma predisposes patients to organic laryngeal lesions or increases dysphonia in those without organic laryngeal lesions. We performed a cross-sectional study with data from the Korea National Health and Nutrition Examination Survey; 19,330 subjects from 2008 through 2011 were included. The associations of asthma with organic laryngeal lesions and dysphonia were analyzed using a simple/multiple logistic regression analysis with complex sampling while adjusting for confounding factors (age, sex, smoking status, stress level, and body mass index) that could contribute to dysphonia. Compared with non-asthma participants, the asthma patients tended to be older and female and to have higher stress levels. These factors were associated with dysphonia (Age, AOR = 1.20, 95% CI = 1.14 = 1.23, P dysphonia. Compared with non-asthma participants, asthma patients who had not taken asthma medication recently showed a higher AOR (1.62; 95% CI = 1.0-2.42) for dysphonia, and asthma patients who had taken asthma medication recently showed the highest adjusted odds ratio for dysphonia (AOR = 1.97; 95% confidence interval, CI = 1.28-3.02, P = 0.001). On multiple logistic regression analysis, vocal nodules, laryngeal polyps, and laryngitis were not associated with asthma (all P > 0.05). Asthma patients are predisposed to subjective dysphonia due to demographic and clinical characteristics (older age, female, and higher stress level) as well as to asthma itself. However, asthma was not associated with organic laryngeal lesions in this study.

    We reviewed 24 'real-life' effectiveness studies of omalizumab in the treatment of severe allergic asthma that included 4117 unique patients from 32 countries with significant heterogeneity in patients, clinicians and settings. The evidence underscores the short- and long-term benefit of anti-IgE therapy in terms of the following: improving lung function; achieving asthma control and reducing symptomatology, severe exacerbations and associated work/school days lost; reducing healthcare resource utilizations, in particular hospitalizations, hospital lengths of stay and accident specialist or emergency department visits; reducing or discontinuing other asthma medications; and improving quality of life - thus confirming, complementing and extending evidence from randomized trials. Thus, omalizumab therapy is associated with signal improvements across the full objective and subjective burden of illness chain of severe allergic asthma. Benefits of omalizumab may extend up to 2-4 years, and the majority of omalizumab-treated patients may benefit for many years. Omalizumab has positive short- and long-term safety profiles similar to what is known from randomized clinical trials. Initiated patients should be monitored for treatment response at 16 weeks. Those showing positive response at that time are highly likely to show sustained treatment response and benefit in terms of clinical, quality of life and health resource utilization outcomes. © 2015 John Wiley & Sons A/S.

    Environmental pollution, local climatic conditions and their association with the prevalence and exacerbation of asthma are topics of intense current medical investigation. Air pollution in the area of Vladivostock was estimated both by the index of emission volumes of "air gaseous components" (nitrogen oxide and nitrogen dioxide, formaldehyde, hydrogen sulfide, carbon monoxide) in urban atmosphere and by mass spectrometric analysis of precipitates in snow samples. A total of 172 local asthma patients (101 controlled-asthma patients-CAP and 71 non-controlled asthma patients - nCAP) were evaluated with the use of spirometry and body plethysmography. Airway obstruction reversibility was evaluated with the use of an inhaled bronchodilator. Using discriminant analysis the association of environmental parameters with clinical indices of asthma patients is explored and thresholds of impact are established. CAP presented high sensitivity to large-size suspended air particles and to several of the studied climatic parameters. Discriminant analysis showed high values of Wilks' lambda index (α = 0.69-0.81), which implies limited influence of environmental factors on the respiratory parameters of CAP. nCAP were more sensitive and susceptible to the majority of the environmental factors studied, including air suspended toxic metals particles (Cr, Zn and Ni). Air suspended particles showed higher tendency for pathogenicity in nCAP population than in the CAP, with a wider range of particle sizes being involved. Dust fractions ranging from 0 to 1 μm and from 50 to 100 μm were additionally implicated compared to CAP group. Considerably lowest thresholds levels of impact are calculated for nCAP.

    Many asthma patients seek alternative or adjunctive therapies. One such modality is reflexology, whereby finger pressure is applied to certain parts of the body. The aim of the study was to examine the popular claim that reflexology treatment benefits bronchial asthma. Ten weeks of active...... or simulated (placebo) reflexology given by an experienced reflexologist, were compared in an otherwise blind, controlled trial of 20+20 outpatients with asthma. Objective lung function tests (peak flow morning and evening, and weekly spirometry at the clinic) did not change. Subjective scores (describing...... diaries was carried out. It was accompanied by a significant pattern compatible with subconscious unblinding, in that patients tended to guess which treatment they had been receiving. No evidence was found that reflexology has a specific effect on asthma beyond placebo influence....

    Although asthma can be well controlled by appropriate medication delivered in an appropriate way at an appropriate time, there is evidence that management is often suboptimal. This results in poor asthma control, poor quality of life, and significant morbidity. The objective of this study was to describe a population recruited in community pharmacy identified by trained community pharmacists as being at risk for poor asthma outcomes and to identify factors associated with poor asthma control. It used a cross-sectional design in 96 pharmacies in metropolitan and regional New South Wales, Victoria, Queensland, and Australian Capital Territory in Australia. Community pharmacists with specialized asthma training enrolled 570 patients aged ≥18 years with doctor-diagnosed asthma who were considered at risk of poor asthma outcomes and then conducted a comprehensive asthma assessment. In this assessment, asthma control was classified using a symptom and activity tool based on self-reported frequency of symptoms during the previous month and categorized as poor, fair, or good. Asthma history was discussed, and lung function and inhaler technique were also assessed by the pharmacist. Medication use/adherence was recorded from both pharmacy records and the Brief Medication Questionnaire (BMQ). The symptom and activity tool identified that 437 (77%) recruited patients had poor asthma control. Of the 570 patients, 117 (21%) smoked, 108 (19%) had an action plan, 372 (69%) used combination of inhaled corticosteroid (ICS)/long-acting β(2)-agonist (LABA) medications, and only 17-28% (depending on device) used their inhaler device correctly. In terms of adherence, 90% had their ICS or ICS/LABA dispensed <6 times in the previous 6 months, which is inconsistent with regular use; this low adherence was confirmed from the BMQ scores. A logistic regression model showed that patients who smoked had incorrect inhaler technique or low adherence (assessed by either dispensing history or

    Obesity is a risk factor for asthma, but standard asthma drugs have reduced efficacy in the obese. Obesity alters the gastrointestinal microbial community structure. This change in structure contributes to some obesity-related conditions and also could be contributing to obesity-related asthma. Although currently unexplored, obesity may also be altering lung microbiota. Understanding the role of microbiota in obesity-related asthma could lead to novel treatments for these patients.

To help attain the best possible clinical outcomes in patients with asthma, several guidelines provide recommendations for patients who will require a referral to a specialist. Such referrals can help in clearing the uncertainty from the initial diagnosis, provide tailored treatment options to patients with persistent symptoms and offer the patients access to health care providers with expertise in the management of the asthma; thus, specialist referrals have a substantial impact on disease prognosis and the patient’s health status. Hurdles in implementing these recommendations include lack of their dissemination among health care providers and nonadherence to these guidelines; these hurdles considerably limit the implementation of specialist referrals, eventually affecting the rate of referrals. In this review, recommendations for specialist referrals from several key international and national asthma guidelines and other relevant published literature are evaluated. Furthermore, we highlight why referrals are not happening, how this can be improved, and ultimately, what should be done in the specialist setting, based on existing evidence in published literature.

    In asthma patients, the assessment of activity limitation is based on questions evaluating how limited the patient feels in their activities. However, the lack of functional data complicates the interpretation of the answers. We aimed to evaluate the intensity of relationships between the patient's perception of activity limitation and the results of several functional tests. Twenty patients complaining of asthma exacerbation were invited to complete three scores (Chronic Respiratory Disease questionnaire, Asthma Control Questionnaire, Hospital Anxiety and Depression scale). They also underwent lung function measurements, a 6-minute walk test and a cardio-pulmonary exercise test. In addition, physical activity was studied by actigraphy. Spearman's rank correlation coefficients between the patient's perception of activity limitation and each of the other parameters were analysed. Five parameters were significantly correlated with the perception of activity limitation: ACQ question 4, related to dyspnea (rs 0.74, p perception of activity limitation. In response to questions about limitation of activity, patients do not specifically answer mentioning physical limitation but rather the psychological burden associated with this constraint.

    There is a strong association between chronic rhinosinusitis (CRS) and asthma. Approximately 10%-50% of CRS patients also have comorbid asthma. These patients are more likely to have severe CRS and asthma and higher recurrence rates after sinus surgery. Also there may be acute asthma attack during the perioperative period. Therefore, we should pay more attention to these patients. Assessment of the control level of asthma and pulmonary function should be performed preoperatively. And asthma needs to be fully managed in the perioperative period to avoid acute asthma attack. Extensive sinus surgery is recommended in these patients to reduce the inflammation load. Long-term medical treatment and regular follow-up are suggested to achieve well control of CRS and asthma.

    The Asthma Insight and Management (AIM) survey was conducted in North America, Europe, the Asia-Pacific region and Latin America to characterize patients' insights, attitudes and perceptions about their asthma and its treatment. We report findings from the Asia-Pacific survey. Asthma patients (≥12 years) from Australia, China, Hong Kong, India, Malaysia, Singapore, South Korea, Taiwan and Thailand were surveyed. Patients answered 53 questions exploring general health, diagnosis/history, symptoms, exacerbations, patient burden, disease management, medications/treatments and patient's attitudes. The Global Initiative for Asthma guidelines were used to assess asthma control. The survey was conducted by random digit telephone dialling (Australia, China and Hong Kong) or by random face-to-face interviews (India, Malaysia, Singapore, South Korea, Taiwan and Thailand). There were 80 761 households screened. Data from 3630 patients were collected. Wide disparity existed between objective measures of control and patient perception. Reported exacerbations during the previous year ranged from 19% (Hong Kong) to 67% (India). Reported unscheduled urgent/emergency visits to a doctor's office/hospital/clinic in the previous year ranged from 15% (Hong Kong) to 46% (Taiwan). Patients who reported having controlled asthma in the previous month ranged from 27% (South Korea) to 84% (Taiwan). Substantial functional and emotional limitations due to asthma were identified by 13% (South Korea) to 78% (India) of patients. Asthma has a profound impact on patients' well-being despite the availability of effective treatments and evidence-based management guidelines. Substantial differences across the surveyed countries exist, suggesting unmet, country-specific cultural and educational needs. A large proportion of asthma patients overestimate their level of control. © 2013 The Authors. Respirology © 2013 Asian Pacific Society of Respirology.

    Objective: To investigate the therapeutic effect of oral liquid preparation of astragalus membranaceous in aged patients with chronic bronchial asthma with special reference on the serum SOD levels. Methods: Serum SOD levels were measured with RIA in 42 aged patients with chronic bronchial asthma both before and after a course of treatment with oral liquid preparation of astragalus membranaceous (10ml b. i. d for 3 months) as well as in 35 controls. Results: The patients general condition was greatly improved after the treatment. Before treatment, the serum SOD levels in the patients were significantly lower than those in controls (P 0.05). Conclusion: Oral liquid preparation of astragalus membranaceous was therapeutically useful for chronic bronchial asthma in aged patients with correction of the serum SOD levels. (authors)

    Full Text Available To characterize the clinical features of fatal asthma, we retrospectively analyzed the clinical characteristics of patients who died of an acute asthma attack in our hospital during a 15-year period from 1989 to 2003. Twelve patients had fatal asthma during this period, including eight who were dead on arrival in the emergency room (ER and three who died within 1 hour of admission to the ER. Patients were categorized into three groups according to the clinical presentations during the fatal attack: (1 rapid (< 3 hours decompensation in four patients; (2 gradual development of respiratory failure over several days in two patients; and (3 acute deterioration after unstable asthma lasting several days in six patients. All patients in groups 1 and 2 had reported previous near-fatal attacks. The proportion of young patients was highest in group 3, with half of them (3/6 younger than 35 years of age. Only one patient in group 3 had had a previous near-fatal attack. Five of the seven patients, with previous near-fatal attacks, had a pattern of decompensation during their fatal attack that was similar to their previous attacks. In conclusion, nearly all patients with fatal asthma in this study died outside of the hospital or within 1 hour after admission to the ER. Patients had patterns of decompensation during the fatal attack that were similar to those of their previous attacks. Early detection of warning signs, early admission to the ER, adequate treatment, and extremely close observation of patients, especially within 1 hour after ER arrival, may prevent or decrease the incidence of fatal asthmatic attack.

    The current study focused on the role of trait mindfulness in asthma-related quality of life (QoL) and asthma control in adolescent asthma patients. Furthermore, potential underlying mechanisms (general and asthma-specific stress) of this relationship were investigated. In this cross-sectional study, questionnaire data of 94 adolescents with asthma that were prescribed daily asthma medication were included. Two Structural Equation Models (SEMs), a direct model and an indirect model, were tested. We found that trait mindfulness was directly related to asthma-related QoL, but not to asthma control. The relationship between trait mindfulness and asthma-related QoL was explained by asthma-specific, but not by general stress. Furthermore, an indirect relation from mindfulness to asthma control via asthma-specific stress was found. Cross-sectional evidence for a relation between mindfulness and asthma-related QoL is found. These findings may point to the possibility that an intervention aimed at increasing mindfulness could be a promising tool to improve asthma-related QoL in adolescents via a decrease in asthma-specific stress.

    Full Text Available Study objectives were to compare the numbers of lymphocytes and lymphocyte subpopulations in induced sputum from asthmatic patients and from healthy subjects, and to determine the effect of inhaled anti-asthmatic steroid therapy on these cell numbers. Hypertonic saline inhalation was used to non-invasively induce sputum samples in 34 patients with bronchial asthma and 21 healthy subjects. The sputum samples were reduced with dithioerythritol and absolute numbers of lymphocytes and lymphocyte subpopulations were assessed by direct immunofluorescence and flow cytometry. To assess the effect of beclomethasone dipropionate (BDP on induced sputum, numbers of lymphocytes and lymphocyte subpopulations in sputum also were evaluated after 4 weeks of BDP inhalation treatment in seven asthmatic patients. An adequate sample was obtained in 85.3% of patients with asthma and in 79.2% of the healthy subjects. Induced sputum from patients with asthma had increased numbers of lymphocytes (P = 0.009; CD4+ cells (P = 0.044; CD4+ cells-bearing interleukin-2 receptor (CD25; P = 0.016; and CD4+ cells bearing human histocompatibility leukocyte antigen (HLA-DR (P = 0.033. CD8+ cells were not increased in asthmatic patients. In patients treated with inhaled steroids, numbers of lymphocytes, CD4+ cells, CD25-bearing CD4+ cells and HLA-DR-bearing CD4+ cells in sputum decreased from pretreatment numbers (P = 0.016, 0.002, 0.003 and 0.002, respectively. Analysis of lymphocytes in induced sputum by flow cytometry is useful in assessing bronchial inflammation, and activated CD4+ lymphocytes may play a key role in the pathogenesis of airway inflammation in bronchial asthma.

    Fibromyalgia can affect the control of asthma when both diseases are present in a single patient. To characterize asthma in patients with concomitant fibromyalgia to assess whether fibromyalgia is an independent factor of asthma severity that influences poor asthma control. We also evaluated how dyspnea is perceived by patients in order to demonstrate that alterations in the perception of airway obstruction may be responsible for poor asthma control. This was a cross-sectional case-control multicenter study, in which 56 patients in the asthma and fibromyalgia group were matched to 36 asthmatics by sex, approximate age, and asthma severity level. All patients were women. Study variables included the Asthma Control Test (ACT), the Mini Asthma Quality of Life Questionnaire (MiniAQLQ), the Nijmegen hyperventilation syndrome questionnaire, the Hospital Anxiety and Depression Scale, and perception of dyspnea after acute bronchoconstriction. Although patients in both study groups showed similar asthma severity and use of anti-asthmatic drugs, patients in the asthma and fibromyalgia group showed lower scores on the ACT and MiniAQLQ questionnaires, and higher scores of anxiety and depression as well as hyperventilation compared to asthma patients without fibromyalgia. All these differences were statistically significant. Fibromyalgia in patients with asthma influences poor control of the respiratory disease and is associated with altered perception of dyspnea, hyperventilation syndrome, high prevalence of depression and anxiety, and impaired quality of life. Fibromyalgia may be considered a risk factor for uncontrolled asthma in patients suffering from asthma and fibromyalgia concomitantly.

    A small subgroup of patients with asthma suffers from severe disease that is either partially controlled or uncontrolled despite intensive, guideline-based treatment. These patients have significantly impaired quality of life and although they constitute asthma patients, they are responsible for more than half of asthma-related healthcare costs. Here, we review a definition for severe asthma and present all therapeutic options currently available for these severe asthma patients. Moreover, we suggest a specific algorithmic treatment approach for the management of severe, difficult-to-treat asthma based on specific phenotype characteristics and biomarkers. The diagnosis and management of severe asthma requires specialised experience, time and effort to comprehend the needs and expectations of each individual patient and incorporate those as well as his/her specific phenotype characteristics into the management planning. Although some new treatment options are currently available for these patients, there is still a need for further research into severe asthma and yet more treatment options. PMID:29531957

  20. Pseudo-asthma: when cough, wheezing, and dyspnea are not asthma.

    2007-10-01

    Although asthma is the most common cause of cough, wheeze, and dyspnea in children and adults, asthma is often attributed inappropriately to symptoms from other causes. Cough that is misdiagnosed as asthma can occur with pertussis, cystic fibrosis, primary ciliary dyskinesia, airway abnormalities such as tracheomalacia and bronchomalacia, chronic purulent or suppurative bronchitis in young children, and habit-cough syndrome. The respiratory sounds that occur with the upper airway obstruction caused by the various manifestations of the vocal cord dysfunction syndrome or the less common exercise-induced laryngomalacia are often mischaracterized as wheezing and attributed to asthma. The perception of dyspnea is a prominent symptom of hyperventilation attacks. This can occur in those with or without asthma, and patients with asthma may not readily distinguish the perceived dyspnea of a hyperventilation attack from the acute airway obstruction of asthma. Dyspnea on exertion, in the absence of other symptoms of asthma or an unequivocal response to albuterol, is most likely a result of other causes. Most common is the dyspnea associated with normal exercise limitation, but causes of dyspnea on exertion can include other physiologic abnormalities including exercise-induced vocal cord dysfunction, exercise-induced laryngomalacia, exercise-induced hyperventilation, and exercise-induced supraventricular tachycardia. A careful history, attention to the nature of the respiratory sounds that are present, spirometry, exercise testing, and blood-gas measurement provide useful data to sort out the various causes and avoid inappropriate treatment of these pseudo-asthma clinical manifestations.

    Full Text Available Bente Arboe, Charlotte Suppli UlrikDepartment of Pulmonary Medicine, Hvidovre Hospital and University of Copenhagen, Hvidovre, DenmarkBackground and aim: Recently, β-blockers have been suggested as a potential maintenance treatment option for asthma. The aim of this review is to provide an overview of the current knowledge of the potential benefits and risks of β-blocker therapy for asthma.Method: Systematic literature review.Results: No significant increase in the number of patients requiring rescue oral corticosteroid for an exacerbation of asthma has been observed after initiation of β-blocker treatment. Patients with mild to moderate reactive airway disease, probably both asthma and chronic obstructive pulmonary disease, may have a limited fall in forced expiratory volume in 1 second (FEV1 following single-dose administration of β-blocker, whereas no change in FEV1 has been reported following long-term administration. In a murine model of asthma, long-term administration of β-blockers resulted in a decrease in airway hyperresponsiveness, suggesting an anti-inflammatory effect. In keeping with this, long-term administration of a nonselective β-blocker to steroid-naïve asthma patients has shown a dose-dependent improvement in airway hyperresponsiveness, and either an asymptomatic fall in FEV1 or no significant change in FEV1. Furthermore, available studies show that bronchoconstriction induced by inhaled methacholine is reversed by salbutamol in patients on regular therapy with a β-blocker. On the other hand, a recent placebo-controlled trial of propranolol and tiotropium bromide added to inhaled corticosteroids revealed no effect on airway hyperresponsiveness and a small, not statistically significant, fall in FEV1 in patients classified as having mild to moderate asthma.Conclusion: The available, although limited, evidence suggests that a dose-escalating model of β-blocker therapy to patients with asthma is well tolerated, does not

    Full Text Available Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma.

    Human metapneumovirus (hMPV), an enveloped RNA virus classified in Paramyxoviridae family, was first characterized in 2001 from children with acute respiratory tract infection. Recent studies have suggested hMPV to play a role in chronic obstructive pulmonary disease (COPD) and asthma attacks. The aims of this study were to investigate the frequency of hMPV in patients with COPD and asthma, its effects on the severity of the attacks and the relationship between demographical and clinical factors. A total of 123 patients, including 66 with COPD (45 were in attack and 21 were stable) and 57 with asthma (33 were in attack and 24 were under control) diagnosed according to the criteria of Global Initiative for Chronic Obstructive Lung Disease and the Global Strategy for Asthma Management and Prevention, respectively, were included in the study. Nasopharyngeal lavage samples collected from all of the patients have been evaluated for the presence of hMPV-RNA by using a reverse transcriptase-polymerase chain reaction (RT-PCR) targeting F gene region of the virus. hMPV-RNA positivity rates in patients with COPD and asthma were observed as 30.3% (20/66) and 31.6% (18/57), respectively, and the difference between the groups were not statistically significant (p= 1.00). When patients were compared according to their disease status, hMPV was detected in 31.1% (14/45) of patients with COPD attack and 28.6% of stable patients (p> 0.05). These rates were found as 36.4% (12/33) and 25% (6/24) in patients with asthma attack and controlled asthma, respectively (p> 0.05). Although the virus detection rates in patients with COPD and asthma attacks (26/78; 33.3%) were higher than the patients with stable/controlled disease (12/45; 26.7%), the difference was not found as statistically significant (p= 0.57). The detection rate of hMPV-RNA was 26.1% in patients who can be treated at home and hospital without any need of intensive care and mechanical ventilation, while this rate was 36

    Few studies have assessed the relationships between xerostomia and the use of inhaled corticosteroids (ICS). The main objective of this study was to investigate the prevalence of xerostomia in a respiratory outpatient clinic and its relationship with bronchial asthma and ICS use. A cross-sectional observational study of patients recruited in an outpatient setting divided them according to previous diagnoses of bronchial asthma. Data about pulmonary function, concomitant medication, medical comorbidities, Xerostomia Inventory test (XI test), and the degree of asthma control by ACT (asthma control test) were collected for each patient. A linear regression model was applied, using the XI score as dependent variable and the ACT score as independent variable. The 57 patients were divided into asthmatics (40 patients, 70.2%) and control group without asthma (17, 29.8%). The prevalence of xerostomia was 87.7% (50 patients), with no differences between the study groups or current dose of ICS. In the asthmatic group, patients with uncontrolled asthma had worse XI scores than those with partially or totally controlled asthma (30.43 ± 8.71 vs. 24.92 ± 8.08; P Xerostomia is a common symptom in the ambulatory setting.

However, the role of cannabis consumption in asthma patients and allergic clinical situations still remains controversial. To review the evidence of asthma and allergic diseases associated with the use of marijuana, we conducted a search of English, Spanish, and Portuguese medical using the search terms asthma, allergy, marijuana, marihuana, and cannabis. Entries made between January 1970 and March 2017 were retrieved. Several papers have shown the relationship between marijuana use and increase in asthma and other allergic diseases symptoms, as well as the increased frequency of medical visits. This narrative review emphasizes the importance to consider cannabis as a precipitating factor for acute asthma and allergic attacks in clinical practice. Although smoking of marijuana may cause respiratory symptoms, there is a need for more studies to elucidate many aspects in allergic asthma patients, especially considering the long-term use of the drug. These patients should avoid using marijuana and be oriented about individual health risks, possible dangers of second-hand smoke exposure, underage use, safe storage, and the over smoking of marijuana.

    To analyze and summarize the effect of continuous care on the life quality and control of asthma of pediatric patients with asthma discharged from multiple hospitals. Retrospective analysis was carried out on 172 pediatric patients with asthma aged between 6 and 11 yr old randomly selected from those admitted to five hospitals between January 2014 and December 2015. Among these 172 patients, only 86 (intervention group) received the continuous care between January 2015 and December 2015, while the rest (control group) did not receive from January 2014 and December 2014. After the patients in the intervention group were discharged from the hospital, the ratio of practical forced expiratory volume in one second (FEV1) to the expected FEV1 at the 12 th month was (90.28±10.35)%, and the ratio of peak expiratory flow to the expected value was (84.24±3.43)%, respectively higher than those [(82.73±8.86)% and (75.80±4.67)%] in the control group. Regarding pediatric asthma quality of life questionnaire (PAQLQ) between the intervention group and the control group, the difference had statistical significance ( Z =-7.254, PContinuous care can improve the pediatric patient's pulmonary function and life quality, and effectively control the asthmatic symptoms.

    Highlights: ► IL-33 is considered a new therapeutic target for reducing inflammation in asthma. ► This study shows that IL-33 is a potent chemoattractant for fibrocytes in asthma. ► IL-33 also promotes fibrocyte proliferation without reducing collagen production. ► The study uncovers a novel non-inflammatory, profibrotic function of IL-33. -- Abstract: The release of IL-33 increases in the bronchial mucosa of asthmatic patients in relation to disease severity and several studies have demonstrated that IL-33 may enhance airway inflammation in asthma. This study tested the hypothesis that IL-33 may also contribute to the development of irreversible structural changes in asthma by favoring the airway recruitment and profibrotic function of circulating fibrocytes during episodes of allergen-induced asthma exacerbation. The circulating fibrocytes from patients with allergen-exacerbated asthma (PwAA) showed increased expression of the specific IL-33 receptor component ST2L in comparison with the cells from non-asthmatic individuals (NAI). Recombinant IL-33 induced the migration of circulating fibrocytes from PwAA at clinically relevant concentrations and stimulated their proliferation in a concentration-dependent manner between 0.1 and 10 ng/ml, without affecting the constitutive release of type I collagen. The recombinant protein did not induce similar responses in circulating fibrocytes from NAI. This study uncovers an important mechanism through which fibrocytes may accumulate in the airways of allergic asthmatics when their disease is not adequately controlled by current treatment and provides novel information on the function of IL-33 in asthma.

    In this prospective, multicenter, randomized, controlled, double-blind study, we investigated the impact of a mobile patient engagement application on health outcomes and quality of life in allergic rhinitis (AR) and asthma patients. In total, 327 patients with diagnoses of persistent AR or mild-to-severe persistent asthma were randomized into 2 intervention groups and 2 control groups upon their admission at outpatient clinics. The intervention groups (POPET-AR and POPET-Asthma) received a mobile phone application ("physician on call patient engagement trial" [POPET]), enabling them to communicate with their physician, and record their health status and medication compliance. The AR groups completed the Rhinitis Quality of Life Questionnaire (RQLQ) at initiation and at the first month of the study. The asthma groups completed the Asthma Control Test (ACT) at initiation and at the third month of the study. The POPET-AR group showed better clinical improvement than the control group in terms of the overall RQLQ score as well in measures of general problems, activity, symptoms other than nose/eye, and emotion domains (p 19) compared with the control group (27%); this was statistically significant (p mobile engagement platform, such as POPET, can have a significant impact on health outcomes and quality of life in both AR and asthma, potentially decreasing the number of hospital admissions, repeat doctor visits, and losses in productivity. Improvements were seen in domains related to activity, productivity, perception of disease, and emotion. © 2015 ARS-AAOA, LLC.

    Full Text Available The increa­sing prevalence of asthma (A and diabetes mellitus type 2 (DM2T necessitates administration of the adequate antia­sthmatic long-term basic therapy with consideration of comorbid states. The purpose consisted in revealing the therapeutic potential of Tiotropium bromide (TB and L-arginine (Tivortine in patients having uncontrolled moderately severe asthma in combination with DM2T (A+DM2T. Forty seven A+DM2T patients underwent an in-depth study before and after their treatment. They were divided into 2 groups: treatment (group 1, n=28 and comparison (group 2, n=19. Both groups received the standard 2-component therapy: budesonide/formoterol fumarate dihydrate – 160/4.5µg by 2 breaths twice a day and metformin at a dose of 500 mg twice a day. The complex of their basic therapy for group 1 additionally included TB (18 µg a day and arginine hydrochloride preparation (Tivortine® aspartate, Yuriya-Farm orally by 15 ml twice a day during 3 months (90 days. The patients were followed up 3 months and one year later. Their general condition demonstrated positive dynamics in both groups, the number of exacerbations in group 1 reducing by a factor of 4. The complex use of L-arginine and TB preparations against a background of the basic therapy in A+DM2T patients produced a better control over the disease, a more rapid elimination of obstruction manifestations, achievement and prolongation of the clinical spirographic remission, an improvement of the quality of life, correction of disturbances in haemocoagulation, fibrinolysis and the functional state of endothelium.

    Asthma self-management is aimed to improve the quality and effectiveness of asthma care by supporting the patients to manage their illness by themselves. The aim of the study was to evaluate the impact of pharmacist-delivered counselling on patients knowledge and beliefs about the medicines, adherence level, and asthma control. A prospective intervention study was conducted in community pharmacies. A total of 90 patients completed the study. Four questionnaires were used: (1) Beliefs about medicines questionnaire (BMQ), (2) Knowledge of asthma and asthma medicine (KAM), (3) Asthma control test (ACT), and (4) 8-item Morisky medication adherence scale questionnaire (MMAS-8). Questionnaires were completed at baseline and 3 months later. Low level of adherence and poor asthma control were determined initially. Better asthma control was significantly associated with higher adherence level, lower concerns regarding the medication use, and knowledge of triggers. Statistically significant improvement was found after 3 months in patients knowledge of asthma and its medications, their attitude towards medications (decrease in harm, overuse and concern; increase in necessity score), asthma control score (increased from 19 to 20, p < 0.05) and level of adherence (MMAS-8 score decreased from 3 to 2 p < 0.05). Better asthma control was achieved in 60% of patients. Sixteen patients (18%) were transferred from poor to well-controlled asthma, implying no need for patients' referral to the doctor and no additional cost for the health system. Improved disease control could be a result of enhanced knowledge and understanding of the disease-medication relationship, improved inhalation technique, and support on patients' adherence. Acquired knowledge and skills, as well as improved attitude, empowered patients to take a more active part in asthma management. Education in further patients' follow-up should consider topics tailored to the patients' characteristics, needs, and prior

    Comprehensive, rapid, and accurate identification of patients with asthma for clinical care and engagement in research efforts is needed. The original development and validation of a computable phenotype for asthma case identification occurred at a single institution in Chicago and demonstrated excellent test characteristics. However, its application in a diverse payer mix, across different health systems and multiple electronic health record vendors, and in both children and adults was not examined. The objective of this study is to externally validate the computable phenotype across diverse Chicago institutions to accurately identify pediatric and adult patients with asthma. A cohort of 900 asthma and control patients was identified from the electronic health record between January 1, 2012 and November 30, 2014. Two physicians at each site independently reviewed the patient chart to annotate cases. The inter-observer reliability between the physician reviewers had a κ-coefficient of 0.95 (95% CI 0.93-0.97). The accuracy, sensitivity, specificity, negative predictive value, and positive predictive value of the computable phenotype were all above 94% in the full cohort. The excellent positive and negative predictive values in this multi-center external validation study establish a useful tool to identify asthma cases in in the electronic health record for research and care. This computable phenotype could be used in large-scale comparative-effectiveness trials.

    Asthma is a leading chronic disorder among children and adolescents. Although some children outgrow asthma while transitioning into adulthood, there are others who continue to suffer from life-threatening asthmatic exacerbations. Teenagers tend to have certain misconceptions about their asthmatic condition and treatment which are rarely recognized or addressed in regular clinical consultations. After reviewing the literature in this field, we have identified that improving patient knowledge can be effective in augmenting engagement, and considerably improving their clinical outcomes. It is necessary to develop an effective educational intervention that can help Asthma patients change their perception about self-efficacy and ultimately reduce the total health care costs incurred. Hence, a sound transfer of knowledge during the transition from childcare to adult care is highly recommended. On these very lines, Georgia Institute of Technology designed an interactive educational application called Asthma Academy in conjunction with Children's Healthcare of Atlanta. This website resides in the public cloud and uses a novel animation video-based curriculum to deliver essential healthcare education to asthmatic adolescents in an interactive manner. What distinguishes it from similar initiatives is the use of a cost-effective technique to simulate caregiver-patient interactions and the ability to cater to a wide range of socio-economic statuses and educational levels. A group-based study with twenty asthma adolescents was conducted to evaluate the user acceptance and performance of Asthma Academy supplemented by regular check-ups over a period of eight to ten weeks. Observations recorded post the study clearly indicate higher levels of engagement and the systematic dissemination of information offered by Asthma Academy.

    Full Text Available Introduction: The objective of this study was to investigate with the help of a computerized simulation model whether the treatment of an acute asthma attack can be individualized based on the severity of the attack and the characteristics of the patient. Material and Method: A stochastic lung model was used to simulate the deposition of 1 nm - 10 μm particles during a mild and a moderate asthma attack. Breathing parameters were varied to maximize deposition, and simulation results were compared with those obtained in the case of a severe asthma attack. In order to investigate the effect of height on the deposition of inhaled particles, another series of simulations was carried out with identical breathing parameters, comparing patient heights of 155 cm, 175 cm and 195 cm. Results: The optimization process yielded an increase in the maximum deposition values of around 6-7% for each type of investigated asthma attack, and the difference between attacks of different degree of severity was around 5% for both the initial and the optimized values, a higher degree of obstruction increasing the amount of deposited particles. Conclusions: Our results suggest that the individualization of asthma attack treatment cannot be based on particles of different size, as the highest deposited fraction in all three types of attacks can be obtained using 0.01 μm particles. The use of a specific set of breathing parameters yields a difference between a mild and a moderate, as well as a moderate and a severe asthma attack of around 5%.

    1. To assess the efficacy of omalizumab therapy in improving sinonasal outcomes in refractory allergic fungal rhinosinusitis (AFRS) patients with moderate or severe asthma. 2. To determine if omalizumab therapy reduces the usage of corticosteroids or antifungal therapy in AFRS patients The clinical charts of patients with AFRS with moderate or severe asthma who received at least three subcutaneous injections of omalizumab therapy between 1st January 2012 and 1st May 2014 were retrospectively reviewed. These patients had undergone bilateral functional endoscopic sinus surgery (FESS) and failed adjunct medical treatments (oral or topical corticosteroids and/or antifungal therapy) prior to omalizumab therapy. Seven patients met the inclusion criteria and were included in this study. The mean age of the patients was 48.14. The average number of subcutaneous omalizumab injections was 7.57 (range 6-11) with a mean dosage of 287mg (range 225-375mg). The mean pre-omalizumab treatment Sino-Nasal Outcome Test-22 (SNOT-22) score was 52.14 while the mean post-omalizumab treatment SNOT-22 score was 35.86 (31% improvement). The mean pre-omalizumab therapy Phillpott-Javer endoscopic score (over the last one year before omalizumab therapy) was 36 while the mean post-omalizumab therapy endoscopic score (from the last clinic visit) was 14 (61% improvement). Omalizumab therapy reduced the dependence of AFRS patients on corticosteroid and antifungal treatments. Omalizumab therapy can be considered as a potential adjunct for the treatment for patients with refractory AFRS with moderate or severe asthma. However, larger prospective studies to confirm the findings of this study will be required. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

    Asthma attack shows strong seasonality. The purpose of the present study was to quantify the contribution of climate variables and other seasonal factors on the incidence of emergency visits for childhood asthma in Tokyo, Japan. The number of children who visited emergency rooms at Jikei university hospitals in Tokyo during 1998-2002 (5559 visits) was retrieved retrospectively from files from the Department of Pediatrics, and compared with 45 climate parameters from the Meteorological Agency using multiple regression models with a stepwise backward elimination approach. The number of visits (3.7 +/- 3.1) per night increased significantly when climate conditions showed a rapid decrease from higher barometric pressure, from higher air temperature and from higher humidity, as well as lower wind speed. The best-fit model demonstrated that a 22% variation in the number of visits was explained by a linear relationship with 12 climate variables, which increased to 36% after adjusting for calendar month and day of the week. Moreover, when the number of asthma visits was cut off at nine per night, the area under the receiver operator characteristics curve was 0.91 (95% CI: 0.89-0.94) in the multiple logistic regression model using the same variables. These results suggest that these models might quantify contributions of specific climate conditions and other seasonal factors on the number of emergency visits per night for childhood asthma attack in Tokyo, Japan.

    Asthma is the most common chronic condition of childhood. Hospitalizations and emergency department (ED) visits for asthma are more frequently experienced by minority children and adolescents and those with low socioeconomic status. To reduce asthma-related hospitalizations and ED visits for Medicaid-insured pediatric patients residing in Hamilton County, Ohio. From January 1, 2010, through December 31, 2015, a multidisciplinary team used quality-improvement methods and the chronic care model to conduct interventions in inpatient, outpatient, and community settings in a large, urban academic pediatric hospital in Hamilton County, Ohio. Children and adolescents aged 2 to 17 years who resided in Hamilton County, had a diagnosis of asthma, and were Medicaid insured were studied. Interventions were implemented in 3 phases: hospital-based inpatient care redesign, outpatient-based care enhancements, and community-based supports. Plan-do-study-act cycles allowed for small-scale implementation of change concepts and rapid evaluation of how such tests affected processes and outcomes of interest. The study measured asthma-related hospitalizations and ED visits per 10 000 Medicaid-insured pediatric patients. Data were measured monthly on a rolling 12-month mean basis. Data from multiple previous years were used to establish a baseline. Data were tracked with annotated control charts and with interrupted time-series analysis. Of the estimated 36 000 children and adolescents with asthma in Hamilton County (approximately 13 000 of whom are Medicaid insured and 6000 of whom are cared for in Cincinnati Children's Hospital primary care practices), asthma-related hospitalizations decreased from 8.1 (95% CI, 7.7-8.5) to 4.7 (95% CI, 4.3-5.1) per 10 000 Medicaid patients per month by June 30, 2014, a 41.8% (95% CI, 41.7%-42.0%) relative reduction. Emergency department visits decreased from 21.5 (95% CI, 20.6-22.3) to 12.4 (95% CI, 11.5-13.2) per 10 000 Medicaid patients per

    Full Text Available Achalasia is characterized by obstruction of the distal esophagus and subsequent dilation of the proximal esophagus, and is considered to be a rare disorder in children. Patients commonly present with gastrointestinal (GI symptoms such as dysphagia; however, pulmonary symptoms may also occur. Rare pulmonary symptoms due to achalasia are dyspnea and wheeze due to tracheal compression. The authors describe an 11-year-old boy who was referred to a pediatric respiratory clinic for asthma that was not responsive to inhaled medications. The child presented with a one-year history of dyspnea on exertion, cough and wheeze. He also complained of chronic dyspepsia. The presence of GI symptoms, in addition to abnormalities on chest radiograph and spirometry, suggested the presence of achalasia. The diagnosis was confirmed and the patient subsequently underwent surgical myotomy that relieved his GI and pulmonary symptoms, and normalized spirometry. The present article is an illustrative case report to remind pediatricians to consider other diagnoses when a patient does not respond to asthma medications.

    The objective of this systematic review was to evaluate the impact of pharmacists' interventions on clinical asthma outcomes on adult patients and to identify the outcome indicators used.PubMed, Scopus, Web of Science and Scielo were searched. Studies addressing pharmacists' interventions on adult asthma patients reporting clinical asthma outcomes were incorporated.11 clinical outcomes were identified in 21 studies. 10 studies measured the impact of the intervention on asthma control. Randomised controlled trials (RCT) and non-RCTs found positive results in percentages of controlled patients and Asthma Control Questionnaire (ACQ) scores. Discordant results were found for Asthma Control Test results. Asthma severity was assessed in four studies. One RCT found a significant decrease in the percentage of severe patients; two non-RCTs found significant improvements in severity scores. 11 studies reported pulmonary function indicators, showing inconsistent results. Eight studies measured asthma symptoms; three RCTs and four non-RCTs showed significant improvements.RCTs and non-RCTs generated similar results for most outcomes. Based on the evidence generated by RCTs, pharmacists' have a positive impact on the percentage of controlled patients, ACQ scores, severity and symptoms. Future research should report using the core outcome set of indicators established for asthma (PROSPERO CRD42014007019). Copyright ©ERS 2016.

    Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). To verify the clinical application of ASM by comparing bronchial measurements obtained by means of the traditional eye-driven method, subpixel method alone and ASM in a group comprised of bronchial asthma patients and healthy individuals. The study included 30 bronchial asthma patients and the control group comprised of 20 volunteers with no symptoms of asthma. The lowest internal and external diameters of the bronchial cross-sections (ID and ED) and their derivative parameters were determined in HRCT scans using: (1) traditional eye-driven method, (2) subpixel technique, and (3) ASM. In the case of the eye-driven method, lower ID values along with lower bronchial lumen area and its percentage ratio to total bronchial area were basic parameters that differed between asthma patients and healthy controls. In the case of the subpixel method and ASM, both groups were not significantly different in terms of ID. Significant differences were observed in values of ED and total bronchial area with both parameters being significantly higher in asthma patients. Compared to ASM, the eye-driven method overstated the values of ID and ED by about 30% and 10% respectively, while understating bronchial wall thickness by about 18%. Results obtained in this study suggest that the traditional eye-driven method of HRCT-based measurement of bronchial tree components probably overstates the degree of bronchial patency in asthma patients.

    Concentrations of endogenous opioid peptides in the plasma are increased during exercise and these substances have been implicated in the pathogenesis of asthma induced by chloropropramide and alcohol in diabetic patients. This work was undertaken to determine whether exercise induced asthma might be mediated by endogenous opioids. Plasma beta endorphin, met-enkephalin, and adrenocorticotrophic hormone (ACTH) concentrations were measured in five asthmatic patients and five normal volunteers breathing cold air during exercise. In four of the patients the effect of an infusion of naloxone on FEV1 was also measured during exercise induced asthma. Exercise produced acute bronchoconstriction in all asthmatics, characterised by a fall in FEV1; whereas no change occurred in normal subjects. There was no difference in plasma met-enkephalin, beta endorphin, and ACTH concentration between the two groups. Infusion of naloxone neither prevented nor worsened exercise induced asthma. These data suggest that endogenous opioids probably do not play a part in the development of exercise induced asthma. PMID:2944240

    This review presents seven national asthma programmes to support the European Asthma Research and Innovation Partnership in developing strategies to reduce asthma mortality and morbidity across Europe. From published data it appears that in order to influence asthma care, national/regional asthma programmes are more effective than conventional treatment guidelines. An asthma programme should start with the universal commitments of stakeholders at all levels and the programme has to be endorsed by political and governmental bodies. When the national problems have been identified, the goals of the programme have to be clearly defined with measures to evaluate progress. An action plan has to be developed, including defined re-allocation of patients and existing resources, if necessary, between primary care and specialised healthcare units or hospital centres. Patients should be involved in guided self-management education and structured follow-up in relation to disease severity. The three evaluated programmes show that, thanks to rigorous efforts, it is possible to improve patients' quality of life and reduce hospitalisation, asthma mortality, sick leave and disability pensions. The direct and indirect costs, both for the individual patient and for society, can be significantly reduced. The results can form the basis for development of further programme activities in Europe.

    Metabolic syndrome (MetS) is a syndrome that involves at least three disorders dyslipidemia, insulin resistance, obesity and/or hypertension. MetS has been associated with several chronic diseases in the adulthood; however, in the recent years, the syndrome was redefined in children. Girls with early menarche and asthma, and children with MetS and asthma that reach adulthood appear to have higher risk to develop severe or difficult to control asthma and a higher probability to suffer cardiovascular diseases. It has been proposed that patients with MetS and endocrinological disorders should be considered a different entity in which pharmacologic treatment should be adjusted according to the individual. Recent patents on the field have addressed new issues on how endocrine control should be managed along with asthma therapeutics. In the near future, new approaches should decrease the high morbidity and mortality associated to these types of patients.

    Full Text Available Asthma is a chronic disorder affecting millions of people worldwide. The prevalence of asthma is around 300 million and is expected to increase another 100 million by 2025. Obesity, on the other hand, also affects a large number of individuals. Overweight in adults is defined when body mass index (BMI is between 25 to 30 kg/m 2 and obesity when the BMI >30 kg/m 2 . It has been a matter of interest for researchers to find a relation between these two conditions. This knowledge will provide a new insight into the management of both conditions. At present, obese asthma patients may be considered a special category and it is important to assess the impact of management of obesity on asthma symptoms.

    Full Text Available Abstract Background Patients are increasingly using complementary therapies, often for chronic conditions. Asthma is the most common chronic condition in the UK. Previous research indicates that some asthma patients experience gaps in their NHS care. However, little attention has been given to how and why patients and parents of children with asthma use complementary therapies and the implications for NHS care. Methods Qualitative study, comprising 50 semi-structured interviews with a purposeful sample of 22 adults and 28 children with asthma (plus a parent, recruited from a range of NHS and non-NHS settings in Bristol, England. Data analysis was thematic, drawing on the principles of constant comparison. Results A range of complementary therapies were being used for asthma, most commonly Buteyko breathing and homeopathy. Most use took place outside of the NHS, comprising either self-treatment or consultation with private complementary therapists. Complementary therapies were usually used alongside not instead of conventional asthma treatment. A spectrum of complementary therapy users emerged, including "committed", "pragmatic" and "last resort" users. Motivating factors for complementary therapy use included concerns about conventional NHS care ("push factors" and attractive aspects of complementary therapies ("pull factors". While participants were often uncertain whether therapies had directly helped their asthma, breathing techniques such as the Buteyko Method were most notably reported to enhance symptom control and enable reduction in medication. Across the range of therapies, the process of seeking and using complementary therapies seemed to help patients in two broad ways: it empowered them to take greater personal control over their condition rather than feel dependant on medication, and enabled exploration of a broader range of possible causes of their asthma than commonly discussed within NHS settings. Conclusion Complementary therapy

    To determine if patterns of predominant asthma disease activity are more closely related than baseline asthma severity to measures of morbidity (acute asthma attack, emergency room visit/hospitalization, missed school days, and/or steroid burst). Retrospective analysis was performed for inner-city Los Angeles asthmatic children (3 to 18 years of age) during their first year of enrollment in an asthma-specific disease management program. All measures of morbidity were more closely related to patterns of predominant disease activity than baseline severity. We conclude that patterns of predominant disease activity are a more significant predictor of asthma morbidity than is baseline severity.

    We sought to compare the characteristics of patients with asthma presenting to the emergency department (ED) during the night-time with those of patients presenting at other times of the day, and to determine whether the time of ED presentation is associated with the risk of hospitalisation. A multicentre chart review study of 23 EDs across Japan. Patients aged 18-54 years with a history of physician-diagnosed asthma, presented to the ED between January 2009 and December 2011 OUTCOME MEASURES: The outcome of interest was hospitalisation, including admissions to an observation unit, inpatient unit and intensive care unit. Among the 1354 patients (30.1% in the night-time group vs 69.9% in the other time group) included in this study, the median age was 34 years and ∼40% were male. Overall 145 patients (10.7%) were hospitalised. Patients in the night-time group were more likely to have a shorter duration of symptoms (≤3 hours) before ED presentation than those in the other time group (25.9% in night-time vs 13.4% in other times; pdifferences in respiratory rate, initial peak expiratory flow or ED asthma treatment between the two groups (p>0.05). Similarly, the risk of hospitalisation did not differ between the two groups (11.3% in night-time vs 10.5% in other times; p=0.65). In a multivariable model adjusting for potential confounders, the risk of hospitalisation in the night-time group was not statistically different from the other time group (OR, 1.10; 95% CI 0.74 to 1.61; p=0.63). This multicentre study in Japan demonstrated no significant difference in the risk of hospitalisations according to the time of ED presentation. Published by the BMJ Publishing Group Limited.

    Virus infection is an important risk factor for aggravation of childhood asthma. The objective of this study was to examine the effect of drugs on aggravation of asthma induced by a common cold. Asthma control was examined in a survey of 1,014 Japanese pediatric patients with bronchial asthma. The occurrence of common cold, asthma control, and drugs used for asthma control were investigated using a modified Childhood Asthma Control Test (C-ACT) for patients aged cold and aggravation of asthma were significantly higher in patients aged cold-induced aggravation was significantly less effective in patients aged cold, asthma control was significantly more effective for those treated with leukotriene receptor antagonists (LTRAs) compared to treatment without LTRAs. Asthma control did not differ between patients who did or did not take inhaled corticosteroids or long-acting β2 stimulants. These findings showed a high prevalence of common cold in younger patients with childhood asthma and indicated that common cold can induce aggravation of asthma. LTRAs are useful for long-term asthma control in very young patients who develop an asthma attack due to a common cold.

    Providing asthma education about controller medication use and appropriate management of asthma exacerbation are the keys to improving the disease outcome. Many asthma guidelines recommend that physicians provide written asthma action plan (WAAP) to all of their asthmatic patients. However, the benefit of WAAP is unclear. Thus, we have created a new WAAP which is simplified in Thai and more user friendly. To determine the effectiveness of the newly developed asthma action plan in management of children with asthma. Asthmatic children who meet inclusion criteria all received the WAAP and they were followed up for 6 months with measurement of outcome variables, such as asthma exacerbation that required emergency room visit, unscheduled OPD visit, admission and school absence in order to compare with the past 6 months before receiving the WAAP. The analyzed outcomes of forty-nine children show significantly reduced emergency room visit (P-value 0.005), unscheduled OPD visit (P-value 0.046), admission days (P-value 0.026) and school absence days (P-value 0.022). Well controlled group and mild severity group were not the factors that contribute to decreased emergency room visit but step up therapy may be the co-factor to decreased ER visit. The results of this study suggest that the provision of newly developed WAAP is useful for improving self-care of asthma patients and reducing asthma exacerbation.

    Highlights: Black-Right-Pointing-Pointer IL-33 is considered a new therapeutic target for reducing inflammation in asthma. Black-Right-Pointing-Pointer This study shows that IL-33 is a potent chemoattractant for fibrocytes in asthma. Black-Right-Pointing-Pointer IL-33 also promotes fibrocyte proliferation without reducing collagen production. Black-Right-Pointing-Pointer The study uncovers a novel non-inflammatory, profibrotic function of IL-33. -- Abstract: The release of IL-33 increases in the bronchial mucosa of asthmatic patients in relation to disease severity and several studies have demonstrated that IL-33 may enhance airway inflammation in asthma. This study tested the hypothesis that IL-33 may also contribute to the development of irreversible structural changes in asthma by favoring the airway recruitment and profibrotic function of circulating fibrocytes during episodes of allergen-induced asthma exacerbation. The circulating fibrocytes from patients with allergen-exacerbated asthma (PwAA) showed increased expression of the specific IL-33 receptor component ST2L in comparison with the cells from non-asthmatic individuals (NAI). Recombinant IL-33 induced the migration of circulating fibrocytes from PwAA at clinically relevant concentrations and stimulated their proliferation in a concentration-dependent manner between 0.1 and 10 ng/ml, without affecting the constitutive release of type I collagen. The recombinant protein did not induce similar responses in circulating fibrocytes from NAI. This study uncovers an important mechanism through which fibrocytes may accumulate in the airways of allergic asthmatics when their disease is not adequately controlled by current treatment and provides novel information on the function of IL-33 in asthma.

    A therapeutic method including extracorporeal x-ray irradiation of the autoblood of patients with bronchial asthma complicated by cortisone dependence and polyvalent drug intolerance, has been elaborated and clinically tested. The use of this method brings about good short-term results in 90% of cases and good long-term results in 40% of cases (14-38 months). It provides an opportunity to give up corticosteroids in more than 60% of patients and to decrease the hormone dose in the rest of cortisone-dependent patients with bronchial asthma. The above therapeutic method can be used as an independent type of treatment, especially in the presence of polyvalent drug allergy and as an element of multiple modality therapy of bronchial asthma patients. The method was used under in-patient conditions only. No side effects were marked in the course of the clinical trial. To carry out this type of therapy, patients should be thoroughly screened

    Asthma and chronic obstructive pulmonary disease (COPD) are two distinct diseases that share a condition of chronic inflammation of the airways and bronchial obstruction. In clinical settings, it is not rare to come across patients who present with clinical and functional features of both diseases, posing a diagnostic dilemma. The overlap condition has been termed asthma-COPD overlap syndrome (ACOS), and mainly occurs in individuals with long-standing asthma, especially if they are also current or former smokers. Patients with ACOS have poorer health-related quality of life and a higher exacerbation rate than subjects with asthma or COPD alone. Whether ACOS is a distinct nosological entity with genetic variants or rather a condition of concomitant diseases that overlap is still a matter of debate. However, there is no doubt that extended life expectancy has increased the prevalence of asthma and COPD in older ages, and thus the probability that overlap conditions occur in clinical settings. In addition, age-associated changes of the lung create the basis for the two entities to converge on the same subject. ACOS patients may benefit from a stepwise treatment similar to that of asthma and COPD; however, the proposed therapeutic algorithms are only speculative and extrapolated from studies that are not representative of the ACOS population. Inhaled corticosteroids are the mainstay of therapy, and always in conjunction with long-acting bronchodilators. The potential heterogeneity of the overlap syndrome in terms of inflammatory features (T helper-1 vs. T helper-2 pathways) may be responsible for the different responses to treatments. The interaction between respiratory drugs and concomitant diseases should be carefully evaluated. Similarly, the effect of non-respiratory drugs, such as aspirin, statins, and β-blockers, on lung function needs to be properly assessed.

    Purpose Asthma is a global health problem, and asthma prevalence in Asia is increasing. The REcognise Asthma and LInk to Symptoms and Experience Asia study assessed patients’ perception of asthma control and attitudes toward treatment in an accessible, real-life adult Asian population. Patients and methods An online survey of 2,467 patients with asthma from eight Asian countries/regions, aged 18–50 years, showed greater than or equal to two prescriptions in previous 2 years and access to social media. Patients were asked about their asthma symptoms, exacerbations and treatment type, views and perceptions of asthma control, attitudes toward asthma management, and sources of asthma information. Results Patients had a mean age of 34.2 (±7.4) years and were diagnosed with asthma for 12.5 (±9.7) years. Half had the Global Initiative for Asthma-defined uncontrolled asthma. During the previous year, 38% of patients visited the emergency department, 33% were hospitalized, and 73% had greater than or equal to one course of oral corticosteroids. About 90% of patients felt that their asthma was under control, 82% considered their condition as not serious, and 59% were concerned about their condition. In all, 66% of patients viewed asthma control as managing attacks and 24% saw it as an absence of or minimal symptoms. About 14% of patients who correctly identified their controller inhalers had controlled asthma compared to 6% who could not. Conclusion Patients consistently overestimated their level of asthma control contrary to what their symptoms suggest. They perceived control as management of exacerbations, reflective of a crisis-oriented mind-set. Interventions can leverage on patients’ trust in health care providers and desire for self-management via a new language to generate a paradigm shift toward symptom control and preventive care.

    Currently, limited information is available to clinicians regarding the long-term efficacy of omalizumab treatment for allergic asthma. In this report, we aimed to (i) systematically review the evidence regarding the long-term efficacy of omalizumab in patients with persistent uncontrolled allergic asthma, and to (ii) discuss the cost-effectiveness evidence published for omalizumab in this patient population. A comprehensive search for randomized controlled trials (RCTs; ≥52 weeks) was performed, and six studies met our final inclusion criteria (n = 2,749). Omalizumab was associated with significant improvements in quality of life and the Global Evaluation of Treatment Effectiveness. Omalizumab also allowed patients to completely withdraw from inhaled corticosteroid therapy and did not increase the overall incidence of adverse events. However, there was insufficient evidence that omalizumab reduced the incidence of exacerbations, and the cost-effectiveness of omalizumab varied across studies. Our data indicated that omalizumab use for at least 52 weeks in patients with persistent uncontrolled allergic asthma was accompanied by an acceptable safety profile, but it lacked effect on the asthma exacerbations. Use of omalizumab was associated with a higher cost than conventional therapy, but these increases may be cost-effective if the medication is used in patients with severe allergic asthma.

    Full Text Available OBJECTIVE: To describe and characterize local adverse effects (in the oral cavity, pharynx, and larynx associated with the use of inhaled corticosteroids (ICSs in patients with moderate or severe asthma. METHODS: This was a cross-sectional study involving a convenience sample of 200 asthma patients followed in the Department of Pharmaceutical Care of the Bahia State Asthma and Allergic Rhinitis Control Program Referral Center, located in the city of Salvador, Brazil. The patients were ≥ 18 years of age and had been using ICSs regularly for at least 6 months. Local adverse effects (irritation, pain, dry throat, throat clearing, hoarseness, reduced vocal intensity, loss of voice, sensation of thirst, cough during ICS use, altered sense of taste, and presence of oral candidiasis were assessed using a 30-day recall questionnaire. RESULTS: Of the 200 patients studied, 159 (79.5% were women. The mean age was 50.7 ± 14.4 years. In this sample, 55 patients (27.5% were using high doses of ICS, with a median treatment duration of 38 months. Regarding the symptoms, 163 patients (81.5% reported at least one adverse effect, and 131 (65.5% had a daily perception of at least one symptom. Vocal and pharyngeal symptoms were identified in 57 (28.5% and 154 (77.0% of the patients, respectively. The most commonly reported adverse effects were dry throat, throat clearing, sensation of thirst, and hoarseness. CONCLUSIONS: Self-reported adverse effects related to ICS use were common among the asthma patients evaluated here.

    Chronic obstructive pulmonary disease (COPD) and asthma may overlap and converge in older people (overlap syndrome). It was hypothesized that patients with overlap syndrome may have different clinical characteristics such as sputum eosinophilia, and better responsiveness to treatment with inhaled corticosteroid (ICS). Sixty-three patients with stable COPD (forced expiratory volume in 1 second [FEV(1)] ≤80%) underwent pulmonary function tests, including reversibility of airflow limitation, arterial blood gas analysis, analysis of inflammatory cells in induced sputum, and chest high-resolution computed tomography. The inclusion criteria for COPD patients with asthmatic symptoms included having asthmatic symptoms such as episodic breathlessness, wheezing, cough, and chest tightness worsening at night or in the early morning (COPD with asthma group). The clinical features of COPD patients with asthmatic symptoms were compared with those of COPD patients without asthmatic symptoms (COPD without asthma group). The increases in FEV(1) in response to treatment with ICS were significantly higher in the COPD with asthma group. The peripheral eosinophil counts and sputum eosinophil counts were significantly higher. The prevalence of patients with bronchial wall thickening on chest high-resolution computed tomography was significantly higher. A significant correlation was observed between the increases in FEV(1) in response to treatment with ICS and sputum eosinophil counts, and between the increases in FEV(1) in response to treatment with ICS and the grade of bronchial wall thickening. Receiver operating characteristic curve analysis revealed 82.4% sensitivity and 84.8% specificity of sputum eosinophil count for detecting COPD with asthma, using 2.5% as the cutoff value. COPD patients with asthmatic symptoms had some clinical features. ICS should be considered earlier as a potential treatment in such patients. High sputum eosinophil counts and bronchial wall thickening on

    We investigated the possibility of preventing common cold-like symptoms as a previously unknown benefit of leukotriene receptor antagonists (LTRAs). A total of 279 adult patients with bronchial asthma referred to our hospital between June and December 2004 were retrospectively analyzed. Patients were divided into LTRA treated and untreated groups. Frequency of acute exacerbations and number of visits to emergency rooms and of hospital admissions were analyzed as indicators of frequency of infections and asthma exacerbation over the previous 12 months. Irrespective of inhaled corticosteroid (ICS) use, frequency of infections was significantly lower in the LTRA treated group (0.3 +/- 0.7 times/year) than in the LTRA untreated group (1.6 +/- 4.2 times/year) (P cold-like symptoms. Frequency of acute exacerbations and number of hospital admissions were significantly lower in the LTRA treated versus LTRA untreated group (0.4 +/- 0.8 versus 2.7 +/- 4.3 times/year and 0.0 +/- 0.2 versus 0.4 +/- 0.7 times/year, respectively; both P cold-like symptoms than those not receiving LTRAs. LTRAs play an important role in reducing the incidence of common cold-like symptoms among asthma patients and in suppressing exacerbation of asthma symptoms possibly associated with these symptoms.

    Analgesic intolerance (AI) appears in approximately 1 % of the general population. The triad of bronchial asthma, nasal polyposis, and analgesic intolerance is called analgesic-induced asthma (AIA). These patients are frequently referred to adult allergy clinics for preoperative evaluation for possible analgesic cross reactivity and intolerance to anesthetic agents. To determine allergic problems related to anesthesia and postoperative pain management in AI patients with and without asthma. The medical records of 45 patients who had been diagnosed with AI between January 1991 and December 2002 in the adult allergy unit and who underwent surgery in the same hospital in the last 4 years were retrospectively analyzed. The mean age of the patients was 44.4 13.4 years and 30 (66.6 %) were female. Thirty-six (80 %) had AIA, 34 (75.6 %) had persistent allergic rhinitis and 21 (46.7 %) had nasal polyps. Fifty-one surgical procedures were performed in 45 patients, in whom ear, nose and throat surgery was the main procedure (64.7 %). Anesthesia was induced with propofol, fentanyl, and vecuronium and was maintained by sevoflurane or isoflurane. Fentanyl was used for early postoperative pain relief. No complications appeared in relation to anesthesia or early pain management except in a 44-year-old AIA woman who had a reaction in the postoperative period after receiving an inappropriate analgesic. None of the patients had anesthesia-related allergic problems. Atropine and diazepam in the premedication, propofol and fentanyl during induction, muscle relaxation facilitation by vecuronium, and sevoflurane or isoflurane for maintenance seem to be a safe general anesthetic choice for analgesic intolerant patients with and without asthma.

    BACKGROUND: Psoriasis and asthma are disorders driven by inflammation. Psoriasis may carry an increased risk of asthma, but the reverse relationship has not been investigated. OBJECTIVES: To investigate the risk of psoriasis in subjects with childhood asthma in a nationwide Danish cohort. METHODS......: Data on all Danish individuals aged 6-14 years at study entry between 1 January 1997 and 31 December 2011 (n = 1,478,110) were linked at an individual level in nationwide registers. Incidence rates per 10,000 person-years were calculated, and incidence rate ratios (IRRs) adjusted for age, sex......, concomitant medication and comorbidity were estimated by Poisson regression models. RESULTS: There were 21,725 cases of childhood asthma and 6586 incident cases of psoriasis. There were 5697 and 889 incident cases of mild and severe psoriasis, respectively. The incidence rates of overall, mild and severe...

    To perform a cost-utility analysis on asthmatic patients on beclomethasone/formoterol fixed combination in Primary Health Care. Material and methods Non-probability sampling was used to select a group of asthmatic patients with moderate/severe persistent severity (GEMA 2009), treated with beclomethasone/formoterol fixed combination, over 18 years, had given their informed consent. The study observation period was 6 months. The variables studied were: age, sex, duration of disease, health resources used, analysis of health related quality of life by EQ-5D and SF-36, and the specific Asthma Quality of Life Questionnaire. For the qualitative variables, the frequency and percentages were calculated, and for the quantitative variables, the mean, SD and 95% CI. Chi-square, Student t-test and ANOVA were used for statistical inference. Comparisons were made with a statistical significance of 0.05. Of the 64 patients that completed the study, 59.4% were female. The mean age was 49 years, and mean disease duration was 93 months. For asthma control, 53% of patients had a prescription pattern of one/12h. All health related quality of life scales were modified with respect to the baseline and the differences were statistically significant. Our patients had a better health related quality of life than Spanish asthma cohort. The incremental cost utility beclomethasone/formoterol versus usual treatment option was € 6,256/QALY.

    Factors associated with asthma remission need to be determined, particularly when remission occurs in adulthood. To evaluate airway responsiveness and inflammation in adult patients in asthma remission compared with adults with mild, persistent symptomatic asthma. Adenosine monophosphate and methacholine responsiveness were evaluated in 26 patients in complete remission of asthma, 16 patients in symptomatic remission of asthma, 29 mild asthmatic patients and 15 healthy controls. Blood sampling and induced sputum were also obtained to measure inflammatory parameters. Perception of breathlessness at 20% fall in forced expiratory volume in 1 s was similar among groups. In subjects with symptomatic remission of asthma, responsiveness to adenosine monophosphate and methacholine was intermediate between mild asthma and complete asthma remission, with the latter group similar to controls. Asthma remission was associated with a shorter duration of disease. Blood immunoglobulin E levels were significantly increased in the asthma group, and blood eosinophils were significantly elevated in the complete asthma remission, symptomatic remission and asthma groups compared with controls. The suppressive function of regulatory T cells was lower in asthma and remission groups compared with controls. A continuum of asthma remission was observed, with patients in complete asthma remission presenting features similar to controls, while patients in symptomatic asthma remission appeared to be in an intermediate state between complete asthma remission and symptomatic asthma. Remission was associated with a shorter disease duration. Despite remission of asthma, a decreased suppressor function of regulatory T cells was observed, which may predispose patients to future recurrence of the disease.

    Aims To describe symptoms and lung function in patients registered with asthma or chronic obstructive pulmonary disease (COPD) in primary care and to examine how spirometry findings fit with general practitioners’ (GPs) diagnoses. Methods Patients aged ≥40 years with a diagnosis of asthma or COPD registered in the electronic medical record during the previous 5 years were recruited at seven GP offices in Norway in 2009–2010. Registered diagnosis, spirometry results, comorbidity, and reported symptoms were compared. Results Among 376 patients, 62% were women. Based on Global Initiative for Chronic Obstructive Lung Diseases criteria, a spirometry diagnosis of COPD could be made in 68.1% of the patients with a previous COPD diagnosis and in 17.1% of those diagnosed with asthma only (P spirometry was 0.50. A restrictive spirometry pattern was found in 19.4% and more frequently in patients diagnosed with both asthma and COPD (23.9%) than in patients diagnosed with COPD only (6.8%, P = 0.003). Conclusion The ability of GPs to differentiate between asthma and COPD seems to have considerably improved during the last decade, probably due to the dissemination of spirometry and guidelines for COPD diagnosis. A diagnosis of COPD that cannot be confirmed by spirometry represents a challenge in clinical practice, in particular when a restrictive pattern on spirometry is found. PMID:22135492

    Although asthma self-management depends on ongoing and accurate self-assessment by the patient, pediatric asthma patients have weak skills in the area of symptom perception. Before developing an asthma game targeted to improving asthma self-management and improved symptom awareness, we sought to identify gaps in existing games. To clarify the role of relatedness and autonomy in asthma health game design, we investigated symptom awareness, vocabulary, and self-determination through a series of semi-structured interviews with children suffering from asthma. Using self-determination theory as a framework, interviews were oriented to patients' illness experience and vocabulary related to symptomatology, as well as to recreational activities. Formative analysis of the interviews reveals attitudes, perceptions, and motivational factors arising in the context of childhood asthma, and it elucidates the images and vocabulary associated with both illness experience and recreational activities. Qualitative assessment of patient perspectives leads to specific recommendations for game design ideas that will support market entry of a spirometer-controlled game for children with asthma.

    Full Text Available Omalizumab is a non-steroidal medication indicated for the treatment of poorly controlled moderate-to-severe allergic asthmatics. This observational study examines the "real world" effectiveness of omalizumab in this population.This is a one year open-label observational study that compared clinical outcomes including total oral corticosteroid use, exacerbation history, measures of quality of life and inflammation in patients with moderate-to-severe allergic asthma, who were prescribed omalizumab as part of their treatment with the year prior to therapy.A total of 99 patients were enrolled at 25 sites in Canada. During the study period, the mean total annual OCS dose was reduced from 2301.5 mg (prednisone equivalents in the year prior to omalizumab to 1130.0 mg (p<0.0001. There was a 71% reduction in asthma exacerbations and 56% of patients on omalizumab remained exacerbation free when compared to the year prior to study entry. Associated with this was reduced health care utilization. There were significant improvements in the Asthma Control Questionnaire (ACQ and Asthma Quality of Life questionnaire (AQLQ Patients with an elevated FeNO at baseline showed a better response to treatment. No new safety issues were identified during the study period.Our study demonstrates that in "real world" clinical practice, after initiating omalizumab, there is a reduction in total OCS use and exacerbation frequency in patients with moderate-to-severe allergic asthma. Patients on treatment reported improved asthma control and quality of life. FeNO may be a useful biomarker to identify patients who may benefit with omalizumab treatment.

    Full Text Available In order to improve the self care abilities of the patients with bronchial asthma a ′Self Care Manual′ (a Booklet of 26 pages on bronchial asthma was prepared. An interview schedule was developed to evaluate the usefulness of the manual. The validity and reliability of both these instruments were established. Five hundred and twenty three diagnosed patients of bronchial asthma (260 in the study group to whom the self care manual was given and 263 controls to whom no specific instructions were given were included in the study. Emotions like ′tension′, ′excessive laughter′, ′sadness′, ′happiness′ and ′anger′ etc. that triggered the symptoms were studied. The effect of self care manual on other emotions (FNx01a total of 8 items like ′anxiety due to the disease′, ′tension of taking medicine′ and ′fear of death′ etc. was also studied. Both groups were followed up at 2 weeks, 6 months and 1 year while the same interview schedule was administered on each visit. It was observed that the emotion scores decreased significantly in both the groups (8.08±5.5, 5.89±4.88, 1.44±4.63 and 1.19±4.01 in the study patients, whereas 8.50±6.30, 7.88±6.21, 7.35±6.03 and 5.97±5.81 in the controls at 0 weeks, 2 weeks, 6 months and 1 year respectively. The emotion scores were significantly less in the study group as compared to controls (unpaired ′t′ = 3.57, 8.52 and 7.67 at 2 weeks, 6 months and 1 year respectively (p< 0.001 Multiple logistic regression analysis showed that the odds ratio of study group patients showing significant improvement in emotion scores was 3.34 (95% CI, 1.78-6.25 and 4.26 (95% CI, 2.34-7.63 at 6 months and 1 year respectively as compared to controls. We concluded that patient education (self care manual in the form of a booklet made significant improvement in the emotions in patients with bronchial asthma.

  14. Managing problematic severe asthma: beyond the guidelines.

    2018-04-01

    This review discusses issues related to managing problematic severe asthma in children and young people. A small minority of children have genuinely severe asthma symptoms which are difficult to control. Children with genuinely severe asthma need investigations and treatments beyond those described within conventional guidelines. However, the majority of children with poor symptom control despite high-intensity treatment achieve improvement in their asthma control once attention has been paid to the basics of asthma management. Basic asthma management requires optimisation of inhaler technique and treatment adherence, avoidance of environmental triggers and self-management education. It is also important that clinicians recognise risk factors that predispose patients to asthma exacerbations and potentially life-threatening attacks. These correctable issues need to be tackled in partnership with children and young people and their families. This requires a coordinated approach between professionals across healthcare settings. Establishing appropriate infrastructure for coordinated asthma care benefits not only those with problematic severe asthma, but also the wider asthma population as similar correctable issues exist for children with asthma of all severities. Investigation and management of genuine severe asthma requires specialist multidisciplinary expertise and a systematic approach to characterising patients' asthma phenotypes and delivering individualised care. While inhaled corticosteroids continue to play a leading role in asthma therapy, new treatments on the horizon might further support phenotype-specific therapy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2011-01-01

    Full Text Available Objective. To review issues related to asthma in sickle cell disease and management strategies. Data Source. A systematic review of pertinent original research publications, reviews, and editorials was undertaken using MEDLlNE, the Cochrane Library databases, and CINAHL from 1947 to November 2010. Search terms were [asthma] and [sickle cell disease]. Additional publications considered relevant to the sickle cell disease population of patients were identified; search terms included [sickle cell disease] combined with [acetaminophen], [pain medications], [vitamin D], [beta agonists], [exhaled nitric oxide], and [corticosteroids]. Results. The reported prevalence of asthma in children with sickle cell disease varies from 2% to approximately 50%. Having asthma increases the risk for developing acute chest syndrome , death, or painful episodes compared to having sickle cell disease without asthma. Asthma and sickle cell may be linked by impaired nitric oxide regulation, excessive production of leukotrienes, insufficient levels of Vitamin D, and exposure to acetaminophen in early life. Treatment of sickle cell patients includes using commonly prescribed asthma medications; specific considerations are suggested to ensure safety in the sickle cell population. Conclusion. Prospective controlled trials of drug treatment for asthma in patients who have both sickle cell disease and asthma are urgently needed.

We performed LSA at 7 points to examine whether the technique could identify the location of airway inflammation in patients with asthma. Patients and methods: Breath sounds were recorded at 7 points on the body surface of 22 asthmatic subjects. Inspiration sound pressure level (ISPL, expiration sound pressure level (ESPL, and the expiration-to-inspiration sound pressure ratio (E/I were calculated in 6 frequency bands. The data were analyzed for potential correlation with spirometry, airway hyperresponsiveness (PC20, and fractional exhaled nitric oxide (FeNO. Results: The E/I data in the frequency range of 100–400 Hz (E/I low frequency [LF], E/I mid frequency [MF] were better correlated with the spirometry, PC20, and FeNO values than were the ISPL or ESPL data. The left anterior chest and left posterior lower recording positions were associated with the best correlations (forced expiratory volume in 1 second/forced vital capacity: r=–0.55 and r=–0.58; logPC20: r=–0.46 and r=–0.45; and FeNO: r=0.42 and r=0.46, respectively. The majority of asthmatic subjects with FeNO ≥70 ppb exhibited high E/I MF levels in all lung fields (excluding the trachea and V50%pred <80%, suggesting inflammation throughout the airway. Asthmatic subjects with FeNO <70 ppb showed high or low E/I MF levels depending on the recording position, indicating uneven airway inflammation. Conclusion: E/I LF and E/I MF are more useful LSA parameters for evaluating airway inflammation in bronchial asthma; 7-point lung

    Full Text Available Abstract Background Attention deficit hyperactivity disorder (ADHD is increasingly recognized as a common disorder not only in children, but also in the adult population. Similarly, asthma also has a substantial prevalence among adults. Previous studies concerning a potential relationship between ADHD and asthma have not presented consistent results. Methods A cross-sectional study of 594 adult patients diagnosed with ADHD, compared with 719 persons from the general population. Information was collected between 1997 and 2005 using auto-questionnaires rating past and present symptoms of ADHD, co-morbid conditions, including asthma, and work status. Results The prevalence of asthma was significantly higher in the ADHD patient group compared to the controls, 24.4% vs. 11.3% respectively (OR = 2.54, 95% CI 1.89-3.44, and controls with asthma scored higher on ratings of both past and present symptoms of ADHD. Female ADHD patients had a significantly higher prevalence of asthma compared to male ADHD patients (30.9% vs. 18.2%, OR = 2.01, CI 1.36-2.95, but in controls a slight female preponderance was not statistically significant. In both ADHD patients and controls, having asthma was associated with an increased prevalence of symptoms of mood- and anxiety disorders. Conclusions The present findings point to a co-morbidity of ADHD and asthma, and these patients may represent a clinical and biological subgroup of adult patients with ADHD.

  20. Asthma in intellectual disability: are we managing our patients appropriately?

    Science.gov (United States)

    2016-01-01

    People with intellectual disability are a vulnerable group of people with asthma that has, to date, largely been ignored in the medical literature. Although guidelines for medication management for people with intellectual disability suggest asthma is treated as for other populations, there are special considerations that should be taken into account when managing asthma in this group. Due to their cognitive impairment as well as comorbidities, they are likely to require support with asthma self-management, including inhaler use. Their varying degrees of autonomy mean that there is often a need to provide education and information to both the person and their caregivers. Educational aims To understand general principles of health of people with intellectual disability and how this affects the healthcare professional’s approach to asthma management. To understand how intellectual disability affects cognition, autonomy and communication, and therefore the ability of a person to self-manage asthma. To recognise ways of mitigating respiratory disease risk in people with intellectual disability. To describe ways for healthcare professionals to support people with intellectual disability and their caregivers in asthma management. PMID:28210318

    Full Text Available Introduction: Asthma is a chronic inflammatory disease which has increased during the last 20 years, putting a strain on medical resources, particularly severe forms of the disease. Treatment in such cases is inhaled corticosteroids and beta agonist drugs that can produce a range of side effects. The aim of this study is to identify echocardiograph abnormalities and correlate them with severity of disease. Methodology: Eight-seven outpatients were selected at the asthma unit of the Gaffree Guinle University Hospital (HUGG. Each patient underwent spirometry, electrocardiogram (ECG and echocardiogram (ECO during the trial within a month maximum. Echocardiograph abnormalities found related to degree of asthma. Statistical analysis was made by nonparametric tests. Results: We found significant differences (p ≤ 0.05 for age, disease duration and haemoglobin saturation (SaO2 between the moderate and severe groups. In the sample a high prevalence of tricuspid insufficiency (41.4% was identified. Conclusions: ECO identified a series of abnormalities that were not always dependent on severity of disease. ECO can identify pulmonary hypertension through calculation of mean pressure of the pulmonary artery.

    Full Text Available We report the case of an asthmatic patient with blunt trachea and left main bronchus injuries who developed acute severe asthma after surgical repair. Despite medical treatment and ventilatory support, asthma persisted with high airway pressures and severe respiratory acidosis. We proposed venovenous extracorporeal life support for CO2 removal which allowed arterial blood gas normalization and airway pressures decrease. Extracorporeal life support was removed on day five after medical treatment of acute severe asthma. So we report the successful use of extracorporeal life support for operated double blunt tracheobronchial injury with acute severe asthma.

    Little data in the literature exist concerning patients with certain underlying medical conditions who receive allergen subcutaneous immunotherapy (SCIT). To survey allergists' experience with SCIT in patients with medical conditions considered to impose an elevated risk for untoward outcomes. A Web-based survey was conducted among members of the American Academy of Allergy, Asthma & Immunology to query about their experience with SCIT in patients with certain medical conditions. There were 1085 replies (21% response), of whom, 86% were U.S. based, 51% were suburban, 31% were academic, 42% were medium-sized practices, and 54% had >15 years' experience. In responders' opinion, SCIT was "contraindicated" in patients with the following: acquired immune deficiency syndrome (AIDS) (48%), cancer (and still receiving active treatment) (33%), severe asthma (32%), and a history of transplantation (30%). Even so, survey responders collectively gave SCIT to >2400 patients for each of these conditions: severe asthma, coronary artery disease, cancer in remission, and autoimmune disorders; and to ≥5400 patients with hypertension and ≥4100 women who became pregnant. The experience of colleagues with these patients rarely resulted in major problems (i.e., activation of underlying disease, systemic reactions to SCIT, or SCIT discontinuation), with the exception of severe asthma (12.5%), initiation of SCIT during pregnancy (5.4%), and AIDS (4.2%). For most other conditions, it was ≤1.5% (e.g., continue during pregnancy, cancer in remission, history of transplantation, positive human immunodeficiency virus and no AIDS). According to the experience of a large group of practicing allergists, the American Academy of Allergy, Asthma & Immunology members, few medical conditions seemed to pose an elevated risk for untoward outcomes from SCIT. Because these are survey results, prospective research might yield even more solid data.

    2006-06-01

    Full Text Available The substantial morbidity caused by asthma suggests that the disease is associated with a large economic burden. The current study analysed the burden of asthma in eight countries in the Asia-Pacific region. Responses to questions regarding resource use from a survey of people with asthma were analysed. Unit costs were obtained for each resource use element. Individual patient costs were estimated and means calculated for each country. A multivariate model was developed to identify potential predictors of resource use. Annual per-patient direct costs ranged from US$108 for Malaysia to US$1,010 for Hong Kong. When productivity costs were included, total per-patient societal costs ranged from US$184 in Vietnam to US$1,189 in Hong Kong. Urgent care costs were responsible for 18–90% of total per-patient direct costs. Overall, total per-patient direct costs were equivalent to 13% of per capita gross domestic product and 300% of per capita healthcare spending. Extremes of age, greater severity of asthma, and poorer general health status were predictive of high cost. The per-patient cost of asthma in these countries is high, particularly when seen in the context of overall per-patient healthcare spending. Strategies to improve asthma control are likely to not only improve patient outcomes, but also to decrease societal costs.

    Patients with uncontrolled asthma are at a greater risk of asthma attacks requiring emergency room visits or hospital admissions. Takotsubo cardiomyopathy is potentially a significant complication in a course of status asthmaticus. We describe a 43-year-old female patient who presented with status asthmaticus that was further complicated with takotsubo cardiomyopathy. Recognizing apical ballooning syndrome is challenging in patients with a history of respiratory disease because the symptoms of the last entity may complicate the diagnostic approach. It is difficult to distinguish clinically apical ballooning syndrome from the acute airway exacerbation itself. Both asthma and takotsubo cardiomyopathy share the same clinical presentation with dyspnea and chest tightness. In our patient, the electrocardiographic abnormalities, the rapidly reversible distinctive characteristics of echocardiography, and the modest elevation of serum cardiac biomarkers levels, in combination with the presence of a stress trigger (severe asthma attack), strongly supported the diagnosis of broken heart syndrome. Clinicians should re-evaluate asthma management and be aware of the complications associated with asthma attacks such as stress-induced cardiomyopathy.

    In pediatric intractable asthma, there is occasionally an association with GERD (gastroesophageal reflux disease). It is not clear in which cases GERD should be suspected or how effective the GERD therapy is in treating the asthma. Twenty-seven preschool children (asthma attack in spite of asthma therapy underwent 24-hour esophageal pH monitoring. We examined retrospectively the incidence of GERD and the effectiveness of famotidine in GERD positive patients. 18 of the 27 patients (66.7%) had positive results (GERD positive group). In 12 of the 15 patients (80%) who underwent GERD therapy (famotidine), respiratory symptoms were decreased. In the GERD positive group, the incidence of acid reflux during waking hours was more frequent than during sleeping hours. In 8 of 12 patients (66.7%) in whom famotidine was effective, cough and wheeze often occurred during the daytime and corresponded with the time when acid reflux must commonly occurred. We conclude that children suffering from recurrent asthma attack in spite of asthma therapy must be examined for the presence of GERD.

    At the Children's Hospital of Georgia (CHOG), we found that outpatient revisits for pediatric asthma were significantly above national norms. According to the NIH, costly hospital revisits for asthma can be prevented through guidelines-based self-management of asthma, central to which, is the use of a written Asthma-Action Plan (AAP). The asthma services literature has emphasized the role of the healthcare provider in promoting asthma self-management using the AAP, to prevent hospital revisits. On the other hand, the asthma policy literature has emphasized the need for community-based interventions to promote asthma self-management. A gap remains in understanding the extent of leverage that healthcare providers may have in preventing hospital revisits for asthma, through effective communication of AAP in the outpatient setting. Our study sought to address this gap. We conducted a 6-month intervention to implement "patient-and-family-centered communication of the AAP" in CHOG outpatient clinics, based on the "change-management" theoretical framework. Provider communication of AAP was assessed through a survey of "Parent Understanding of the Child's AAP." A quasi-experimental approach was used to measure outpatient revisits for pediatric asthma, pre- and post-intervention. Survey results showed that provider communication of the AAP was unanimously perceived highly positively by parents of pediatric asthma patients, across various metrics of patient-centered care. However, there were no statistically significant differences in outpatient "revisit behavior" for pediatric asthma between pre- and post-intervention periods after controlling for several demographic variables. Additionally, revisits remained significantly above national norms. Results suggest limited potential of "effective provider communication of AAP," in reducing outpatient revisits for pediatric asthma; and indicate need for broader community-based interventions to address patient life variables

    Omalizumab is a recombinant humanized anti-IgE monoclonal antibody approved in the US for moderate to severe persistent allergic asthma (severe persistent asthma in the European Union), uncontrolled despite treatment with inhaled corticosteroids and long-acting beta2 agonists. It reduces asthma exacerbations, symptoms, oral corticosteroid doses, and improves quality of life. Omalizumab may have an antiviral effect when used as a preventive therapy for fall exacerbations in children and teenagers. Two proof-of-concept studies have evaluated omalizumab in nonatopic asthma and showed that it is safe and possibly efficacious in some patients. Omalizumab has been successfully studied as add-on to specific immunotherapy in moderate allergic asthma. Its safety in pregnancy has been assessed in the EXPECT registry. Case series also report positive effects in cases of allergic bronchopulmonary aspergillosis, and in nasal disorders frequently associated with asthma. Last, omalizumab may have corticosteroid-sparing effect in a subset of patients with eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome). Recent studies argue in favor of positive effects of omalizumab beyond its current indications in asthma. Well-designed studies are needed in order to demonstrate the safety and efficacy of omalizumab in these possible novel indications.

    Full Text Available The aim of research is to study the state of circadian arterial tension profile in the patients with bronchial asthma and hypertensive disease as comorbid disease. Materials and methods. The research has been performed at 76 patients with bronchial asthma and hypertensive disease as comorbid disease (the main group and 52 patients with hypertensive disease as the comparison group. The groups were comparable with respect to the gender and age sign. Investigation was performed in the period of clinical remission. The main method used in this research was the investigation of day arterial tension profile in the time of its monitoring. Results. It has been revealed the presence of frequent and expressed change from the side of the studied indexes, especially in the patients with comorbid pathology, which were characterized by more frequent and more significant disorders from the side of diastolic blood pressure, especially at night in combination with more considerable and more rapid rise in early morning hours. The day arterial tension profile was characterized either with insufficient decline of arterial pressure at night or, opposite, with its sharp decrease. Specified disorders were increased as far as heaving of main and comorbid diseases, presence of disorders from the side of lipid exchange were not related to the phase of bronchial asthma (remission, exacerbation and level of its flow control.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Over 20 million Americans are affected with asthma. Many will require some type of surgical procedure during which their asthma management should be optimized. Preoperative assessment of asthma should include a specialized history and physical as well as pulmonary function testing. In many asthmatic patients, treatment with systemic corticosteroids and bronchodilators is indicated to prevent the inflammation and bronchoconstriction associated with endotracheal intubation. The use of corticosteroids has not been shown to adversely affect wound healing or increase the rate of infections postoperatively. Preoperative systemic corticosteroids may be used safely in the majority of patients to decrease asthma-related morbidity.

    Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. Perioperative management in these patients involves: (1) adequate control of airway hyperresponsiveness, including detection of purulent sputum and infection before surgery; (2) evidence-based control of anesthesia; and (3) the aggressive use of beta-2 adrenergic stimulants and the systemic administration of steroids for the treatment of acute attacks. Good preoperative control, including the use of leukotriene antagonists, can reduce the incidence of life-threatening perioperative complications. Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

    Asthma management programs, such as the Breathmobile program, have been extremely effective in reducing asthma morbidity and increasing disease control; however, their high start-up costs may preclude their implementation in smaller health systems. In this study, we extended validated asthma disease management principles from the Breathmobile program to a smaller clinic system utilizing existing resources and compared clinical outcomes. Cox-regression analyses were conducted to determine the cumulative probability that a new patient entering the program would achieve improved clinical control of asthma with each subsequent visit to the program. A weekly asthma disease management clinic was initiated in an existing multi-specialty pediatric clinic in collaboration with the Breathmobile program. Existing nursing staff was utilized in conjunction with an asthma specialist provider. Patients were referred from a regional healthcare maintenance organization and patients were evaluated and treated every 2 months. Reduction in emergency department (ED) visits and hospitalizations, and improvements in asthma control were assessed at the end of 1 year. A total of 116 patients were enrolled over a period of 1 year. Mean patient age was 6.4 years at the time of their first visit. Patient ethnicity was self-described predominantly as Hispanic or African American. Initial asthma severity for most patients, classified in accordance with national guidelines, was "moderate persistent." After 1 year of enrollment, there was a 69% and 92% reduction in ED/urgent care visits and hospitalizations, respectively, compared with the year before enrollment. Up to 70% of patients achieved asthma control by the third visit. Thirty-six different patients were seen during 1 year for a total of $15,938.70 in contracted reimbursements. A large-scale successful asthma management program can be adapted to a stationary clinic system and achieve comparable results.

    Research has demonstrated high comorbidity between asthma and panic disorder (PD). Less is known about the relationship between asthma and the Latino cultural idiom of distress of ataques de nervios, as well as the role that psychosocial stressors play. The current study tested the hypotheses that Latino asthma patients who experience PD, ataques de nervios, and/or asthma-related death of a loved one endorse greater psychological triggers of asthma, greater perceived impact of asthma triggers, and greater difficulty controlling such triggers than do those without these conditions. Data originated from an interview conducted prior to a randomized controlled trial in which 292 Latino adults with self-reported asthma were recruited from outpatient clinics in the Bronx, NY. The PRIME-MD Patient Health Questionnaire (PHQ) was used to screen for PD symptoms, while the Structured Clinical Interview for DSM-IV (SCID-I) was used to confirm diagnosis of PD. Lifetime history of ataques de nervios and asthma-related death of a loved one were based upon self-report. Asthma triggers were examined using the Asthma Trigger Inventory (ATI). PD, ataques de nervios, and asthma-related death of a loved one each predicted a higher frequency of psychological asthma triggers, controlling for gender and comorbid medical conditions. Participants with PD also reported greater impact of asthma triggers than those without PD, while no significant differences in perceived control were observed. Providers should screen for PD, ataques de nervios, and asthma-related death of a loved one in Latino asthma patients, given their observed association with emotionally triggered asthma.

    Full Text Available Background. Combined airway hyper responsiveness to cold and hypoosmotic stimuli in asthma patients results in impairment of lung respiration function and poor disease control compared to patients with isolated airway hyper responsiveness to only one of the stimuli or without such responsiveness that can be connected with edema or mucus hypersecretion.Aim. The purpose of the study is the estimation of the processes of mucin secretion, plasma exudation and oxidative stress in response to cold air in asthma patients with combined airway responsiveness to cold and hypoosmotic stimuli using nasal mucosa as a model.Materials and methods. 23 patients with asthma participated in the study. For the nasal lavage procedure, a nasal cavity was pre-washed at least three times in 5-min intervals with 5 ml saline solution (~36 °C. A control nasal lavage was done 5 min after the last washing with a dwelling time of 1 min in the nasal cavity. Directly after the control lavage, a cold air nasal challenge was done: a participant was asked to breathe deeply at the pace of a metronome to ensure hyperventilation inhaling cold air (–20 °C through the nose and exhaling through the mouth for 5 min. Nasal lavages were taken at 1 min, 15, and 30 min after the challenge. Mucin secretion was estimated on the basis of total protein (TP content, total carbohydrates (TC, and water-soluble forms of mucins MUC5AC and MUC5B in the lavage fluids. For the estimation of plasma exudation, the concentration of α2-macroglobulin (α2-MG was measured. Oxidative stress was estimated by the content of thiobarbituric acid-reactive substances (TBARS in lavage fluid. Lung function and airway responsiveness were studied by the forced expiration spirometry method and the bronchial challenge tests with isocapnic cold air hyperventilation (CAHV and distilled water inhalation (DWI.Results. According to the bronchial challenge tests, the patients were divided into groups: 1 without airway

    Full Text Available The aim of our study was to evaluate the role of airway cellular inflammation and the lipid peroxidation level in the development of airway hyperresponsiveness (AHR to inhalation of hypertonic saline (IHS. Methods and Results: The study included the estimation of inflammatory-cellular composition, intracellular concentration of myeloperoxidase (MPO in induced sputum (IS, serum levels of lipid hydroperoxides (LHP, ceruloplasmin, and vitamin E in 29 patients with asthma and 12 healthy persons. AHR to IHS was assessed by spirometry after 3-min IHS via ultrasonic nebulizer. Patients with asthma had higher indices of leukocytes destruction and cytolysis intensity with the increased leukocyte count in IS. Maximum values of neutrophils cytolysis intensity and leukocytic MPO were found in IS of the patients with AHR to IHS. After the bronchial provocation, serum concentration of LHP was higher in these patients in comparison with the patients without the AHR and control groups. In addition, patients with asthma had lower level of antioxidants than healthy subjects. Conclusion: Marked inflammation involving MPO-activated leukocytes and intensive lipid peroxidation underlie the excessive airway response to IHS.

    Full Text Available Background. Respiratory infections are a major cause of asthma exacerbations where neutrophilic inflammation dominates and is associated with steroid refractory asthma. Structural airway cells in asthma differ from nonasthmatics; however it is unknown if neutrophils differ. We investigated neutrophil immune responses in patients who have good (AGood and suboptimal (ASubopt asthma symptom control. Methods. Peripheral blood neutrophils from AGood (ACQ 0.75, n=7, and healthy controls (HC (n=9 were stimulated with bacterial (LPS (1 μg/mL, fMLF (100 nM, and viral (imiquimod (3 μg/mL, R848 (1.5 μg/mL, and poly I:C (10 μg/mL surrogates or live rhinovirus (RV 16 (MOI1. Cell-free supernatant was collected after 1 h for neutrophil elastase (NE and matrix metalloproteinase- (MMP- 9 measurements or after 24 h for CXCL8 release. Results. Constitutive NE was enhanced in AGood neutrophils compared to HC. fMLF stimulated neutrophils from ASubopt but not AGood produced 50% of HC levels. fMLF induced MMP-9 was impaired in ASubopt and AGood compared to HC. fMLF stimulated CXCL8 but not MMP-9 was positively correlated with FEV1 and FEV1/FVC. ASubopt and AGood responded similarly to other stimuli. Conclusions. Circulating neutrophils are different in asthma; however, this is likely to be related to airflow limitation rather than asthma control.

    There is accumulating evidence that airway remodeling, which contributes to airway narrowing, plays a role in the pathogenesis of bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD). Development of the multislice helical CT (MSCT) with improved spatial resolution has made it possible to obtain more precise imaging of small-sized airways. Small-sized airway wall-thickness was measured using the MSCT scan to analyze small-sized airways of smokers and BA patients, and examine the effects of a β 2 agonists on small-sized airway wall-thickness of BA patients. Thirty-six non-asthmatics who participated in the Health Check Program of Iwate Medical University and 25 patients with asthma were recruited. Amongst the 36 non-asthmatics were 20 healthy never-smokers and 15 smokers. The other 25 asthmatics were recruited from the outpatient clinic at Iwate Medical University. MSCT was performed and the right B10 bronchus was chosen for dimensional analysis. Airway wall thickness was expressed as a percentage of wall area (WA%). WA% of the 7 asthmatics before and 30 mim after procaterol (20μg) inspiration were compared. Small-sized airway wall thickness was significantly increased in smokers and patients with asthma compared to healthy never-smokers, when determined by MSCT. Both %V 50 and %V 25 had significant negative correlations with WA% among the healthy never-smokers and smoker population. Procaterol inspiration reduced WA% in the small airway of patients with asthma. Increase of small-sized airway thickness measured by MSCT scan may reflect peripheral obstructive lesions of smokers and BA patients. (author)

    Dysfunctional breathing (DB) is a respiratory disorder, which involves a pattern of breathing too deeply, too superficially and/or too rapidly. In asthma patients, DB may lead to an overestimation of the severity of asthma symptoms, and hence potentially to overtreatment. However, it is not known to which degree DB may affect estimates of asthma control, in a specialist clinical setting. The MAPOut-study examined all patients referred consecutively over a 12-months period for specialist assessment of asthma at the Respiratory Outpatient Clinic at Bispebjerg Hospital in Copenhagen. All patients were examined with the Nijmegen questionnaire with a DB defined as a score ≥23 and the ACQ questionnaire. Linear regression analysis of predictors of ACQ score was performed. Asthma was defined as asthma symptoms and a positive asthma test. Of the 256 patients referred to the lung clinic, data on both the Nijmegen questionnaire and ACQ score was obtained in 127 patients, who were included in the present analysis. Median (range) age: 30 (15-63) years, and 76 (59.8%) were females. DB was found in 31 (24.4%). Asthmatic patients with co-existing DB had a poorer asthma control compared to asthmatics without DB (Median (range) ACQ score: 2.40 (0.20-4.60) vs 1.20 (0.00-4.40); p < 0.001.). A regression analysis showed that the effect of DB on asthma control was independent of airway hyperresponsiveness or airway inflammation in patients with DB. Dysfunctional breathing is common among asthma patients in a specialist setting, and results in a clinically significant underestimation of asthma control, which may potentially lead to overtreatment.

  4. Virus-induced exacerbations in asthma and COPD

    Full Text Available Chronic obstructive pulmonary disease (COPD is characterized by chronic airway inflammation and/or airflow limitation due to pulmonary emphysema. Chronic bronchitis, pulmonary emphysema, and bronchial asthma may all be associated with airflow limitation; therefore, exacerbation of asthma may be associated with the pathophysiology of COPD. Furthermore, recent studies have suggested that the exacerbation of asthma, namely virus-induced asthma, may be associated with a wide variety of respiratory viruses.COPD and asthma have different underlying pathophysiological processes and thus require individual therapies. Exacerbation of both COPD and asthma, which are basically defined and diagnosed by clinical symptoms, is associated with a rapid decline in lung function and increased mortality. Similar pathogens, including human rhinovirus, respiratory syncytial virus, influenza virus, parainfluenza virus and coronavirus, are also frequently detected during exacerbation of asthma and/or COPD. Immune response to respiratory viral infections, which may be related to the severity of exacerbation in each disease, varies in patients with both COPD and asthma. In this regard, it is crucial to recognize and understand both the similarities and differences of clinical features in patients with COPD and/or asthma associated with respiratory viral infections, especially in the exacerbative stage.In relation to definition, epidemiology, and pathophysiology, this review aims to summarize current knowledge concerning exacerbation of both COPD and asthma by focusing on the clinical significance of associated respiratory virus infections.

    Objective: To evaluate paranasal sinuses in patients with stable or acute asthma in order to determine the prevalence of acute bacterial rhinosinusitis. Methods: A cross-sectional study including 30 patients with acute asthma (73% females) treated in the emergency room and 30 patients with stable asthma (80% females) regularly monitored as outpatients. All patients completed a questionnaire on respiratory signs and symptoms and were submitted to ear, nose and throat (ENT) examination, as well as to X-ray and computed tomography (CT) imaging of the sinuses. Results: Based on the clinical diagnosis, the prevalence of acute bacterial rhinosinusitis was 40% in the patients with acute asthma and 3% in those with stable asthma. The ENT examination findings and the imaging findings in isolation were not useful to confirm the diagnosis. Conclusions: In themselves, ENT examination findings, X-ray findings and CT findings were not useful for the diagnosis of acute bacterial rhinosinusitis. Our results provide further evidence that a clinical diagnosis of bacterial rhinosinusitis should be made with caution. (author)

  7. Epidemiological Trends in Asthma

    Full Text Available Many markers of asthma morbidity have shown substantial increases over the past two decades, including family physician visits, use of anti-asthma medications, emergency room visits and hospital admissions. The reported prevalence of diagnosed asthma and of wheezing has increased, especially in children, with accompanying evidence of increased atopy and increased airway responsiveness. Allergen exposure and parental smoking are significant risk factors for childhood wheezing, whereas the influence of outdoor air pollution is uncertain. Increasing use of beta-agonist treatment, which appears to increase the severity of asthma by increasing early and late responses to allergen, may contribute to increased morbidity and mortality, especially if potent beta-agonists are used. Risk factors for asthma mortality include age, smoking, allergy and airway lability, as well as over-reliance on beta-agonists and poor compliance with other aspects of treatment. Following withdrawal of the potent beta-agonist fenoterol in New Zealand, both hospital admissions and mortality from asthma fell abruptly. Continued patient and physician education, with emphasis on avoidance of risk factors and use of appropriate treatment, should reduce morbidity and mortality from asthma in Canada.

    IMPORTANCE In asthma and other diseases, vitamin D insufficiency is associated with adverse outcomes. It is not known if supplementing inhaled corticosteroids with oral vitamin D3 improves outcomes in patients with asthma and vitamin D insufficiency. OBJECTIVE To evaluate if vitamin D supplementation would improve the clinical efficacy of inhaled corticosteroids in patients with symptomatic asthma and lower vitamin D levels. DESIGN, SETTING, AND PARTICIPANTS The VIDA (Vitamin D Add-on Therapy Enhances Corticosteroid Responsiveness in Asthma) randomized, double-blind, parallel, placebo-controlled trial studying adult patients with symptomatic asthma and a serum 25-hydroxyvitamin D level of less than 30 ng/mL was conducted across 9 academic US medical centers in the National Heart, Lung, and Blood Institute’s AsthmaNet network, with enrollment starting in April 2011 and follow-up complete by January 2014. After a run-in period that included treatment with an inhaled corticosteroid, 408 patients were randomized. INTERVENTIONS Oral vitamin D3 (100 000 IU once, then 4000 IU/d for 28 weeks; n = 201) or placebo (n = 207) was added to inhaled ciclesonide (320 µg/d). If asthma control was achieved after 12 weeks, ciclesonide was tapered to 160 µg/d for 8 weeks, then to 80 µg/d for 8 weeks if asthma control was maintained. MAIN OUTCOMES AND MEASURES The primary outcome was time to first asthma treatment failure (a composite outcome of decline in lung function and increases in use of β-agonists, systemic corticosteroids, and health care). RESULTS Treatment with vitamin D3 did not alter the rate of first treatment failure during 28 weeks (28%[95% CI, 21%-34%] with vitamin D3 vs 29% [95% CI, 23%–35%] with placebo; adjusted hazard ratio, 0.9 [95% CI, 0.6–1.3]). Of 14 prespecified secondary outcomes, 9 were analyzed, including asthma exacerbation; of those 9, the only statistically significant outcome was a small difference in the overall dose of ciclesonide required to

    The goal of asthma management is to achieve disease control; however, despite the availability of effective and safe medications, for many patients asthma remains uncontrolled. One reason for this is the fear of long-term side effects from the regular use of inhaled corticosteroids (ICSs). Adverse...... effects of poorly controlled asthma (for example, obesity, pneumonia, and risks to the fetus) can be perceived as side effects of ICSs. Poorly controlled asthma adversely affects children's cardiovascular fitness, while children with well-controlled asthma perform at the same level as their peers....... Children with uncontrolled asthma also have a higher frequency of obesity than children with controlled asthma. Stress can affect asthma control, and children with poorly controlled asthma are more likely to have learning disabilities compared with those with good control. In adults, focused attention...

    2017-01-01

    Background At the Children’s Hospital of Georgia (CHOG), we found that outpatient revisits for pediatric asthma were significantly above national norms. According to the NIH, costly hospital revisits for asthma can be prevented through guidelines-based self-management of asthma, central to which, is the use of a written Asthma-Action Plan (AAP). Purpose The asthma services literature has emphasized the role of the healthcare provider in promoting asthma self-management using the AAP, to prevent hospital revisits. On the other hand, the asthma policy literature has emphasized the need for community-based interventions to promote asthma self-management. A gap remains in understanding the extent of leverage that healthcare providers may have in preventing hospital revisits for asthma, through effective communication of AAP in the outpatient setting. Our study sought to address this gap. Methods We conducted a 6-month intervention to implement “patient-and-family-centered communication of the AAP” in CHOG outpatient clinics, based on the “change-management” theoretical framework. Provider communication of AAP was assessed through a survey of “Parent Understanding of the Child’s AAP.” A quasi-experimental approach was used to measure outpatient revisits for pediatric asthma, pre- and post-intervention. Results Survey results showed that provider communication of the AAP was unanimously perceived highly positively by parents of pediatric asthma patients, across various metrics of patient-centered care. However, there were no statistically significant differences in outpatient “revisit behavior” for pediatric asthma between pre- and post-intervention periods after controlling for several demographic variables. Additionally, revisits remained significantly above national norms. Conclusions Results suggest limited potential of “effective provider communication of AAP,” in reducing outpatient revisits for pediatric asthma; and indicate need for

    Asthma is the most common chronic disorder of childhood and continues to be a leading cause of pediatric hospital admission. The National Asthma Education and Prevention Program (NAEPP) recommends that spirometry be obtained for asthma patients upon hospital admission, after bronchodilation during the acute phase of asthma symptoms, and at least one additional time before discharge from the hospital. The objectives of this study were to describe the use of spirometry in children hospitalized with asthma and to determine association of pulmonary function with future exacerbations. A retrospective cohort study design was utilized involving review of medical records of children ≥5 years old admitted with asthma to Cincinnati Children's Hospital Medical Center from September 1, 2009 to March 31, 2011. Hospitalization or emergency department (ED) visits were identified by the ICD-9-CM codes of having either a primary diagnosis of asthma (493) or a respiratory illness (460-496) plus a secondary diagnosis of asthma. Asthma re-exacerbation was defined as either having an ED visit or hospitalization for asthma that occurred within 3 months after the index hospitalization. All spirometries were performed in a pediatric pulmonary function laboratory. Among 1,037 admissions included in this study, 89 (8.6%) had spirometry that was recommended by a consulting asthma specialist and usually performed on the day of discharge. Spirometries for forty-five of these patients (54.9%) met all acceptability and repeatability criteria of the American Thoracic Society. Patients who performed acceptable spirometry were significantly older (12.4 ± 3.8 vs. 10.7 ± 3.0 years; P = 0.041). The average forced expiratory volume in the first second (FEV1 ) was 84.4 ± 19.7% predicted; forced vital capacity (FVC) was 98.1 ± 16.0% predicted; FEV1 /FVC was 74.6 ± 9.6%; forced expiratory flow at 25-75% (FEF25-75 ) was 61.2 ± 30.1% predicted.

    We investigated retrospectively, the incidence of intraoperative asthmatic attack in patients with bronchial asthma, and compared the past 5-year period (Jan 1, 1979 to Dec 31, 1983) and the recent 5-year period (July 1, 1990 to June 30, 1994). The influence of anesthetic methods, induction agents, and intervals between the most recent attack and anesthesia were evaluated. The incidence of the attack during anesthesia in patients with asthma was similar in both period, 6.7% in the past and 7.8% in the recent period. Patients who had a history of recurrent attacks within 2 years prior to anesthesia tended to have higher incidence of intraoperative attack in both periods. Furthermore, the incidence of asthmatic attack was significantly greater in patients receiving inhalational anesthetics for induction of anesthesia than in those given intravenous anesthetics in the recent period. Although inhalational anesthetics are considered to be used safely for asthmatic patients, care should be taken when volatile anesthetics are administered to asthmatic patients during induction of anesthesia.

    Abstract Objective: Correct inhaler technique is central to effective delivery of asthma therapy. The study aim was to identify factors associated with serious inhaler technique errors and their prevalence among primary care patients with asthma using the Diskus dry powder inhaler (DPI). Methods: This was a historical, multinational, cross-sectional study (2011–2013) using the iHARP database, an international initiative that includes patient- and healthcare provider-reported questionnaires from eight countries. Patients with asthma were observed for serious inhaler errors by trained healthcare providers as predefined by the iHARP steering committee. Multivariable logistic regression, stepwise reduced, was used to identify clinical characteristics and asthma-related outcomes associated with ≥1 serious errors. Results: Of 3681 patients with asthma, 623 (17%) were using a Diskus (mean [SD] age, 51 [14]; 61% women). A total of 341 (55%) patients made ≥1 serious errors. The most common errors were the failure to exhale before inhalation, insufficient breath-hold at the end of inhalation, and inhalation that was not forceful from the start. Factors significantly associated with ≥1 serious errors included asthma-related hospitalization the previous year (odds ratio [OR] 2.07; 95% confidence interval [CI], 1.26–3.40); obesity (OR 1.75; 1.17–2.63); poor asthma control the previous 4 weeks (OR 1.57; 1.04–2.36); female sex (OR 1.51; 1.08–2.10); and no inhaler technique review during the previous year (OR 1.45; 1.04–2.02). Conclusions: Patients with evidence of poor asthma control should be targeted for a review of their inhaler technique even when using a device thought to have a low error rate. PMID:26810934

    Full Text Available Introduction. The refractory asthma refers to the phenotype, which is characterized by severe persistent course with frequent exacerbations and resistance to corticosteroid therapy. This phenotype of asthma can be related to C159T polymorphism of CD14 receptor gene Material and methods. There were studied the C159T polymorphism of CD14 gene in 331 patients with bronchial asthma. The control group consisted of 285 healthy individuals of Crimea. The C159T gene polymorphism of CD14 was detected by allele-specific polymerase chain reaction with electrophoretic detection. The distribution of genotypes was checked according to the law of the Hardy-Weinberg equilibrium by using Fisher's exact test and χ2. There was used logistic regression to determine the difference in the frequency of genotypes and alleles. Results and discussion. In our study have been identified 291 patients with corticosteroid-sensitive and 40 with refractory asthma. The genotype distribution of control (CC – 34%, CT – 51%, CT – 15% and patients with corticosteroid-sensitive asthma (CC – 29%, CT – 53%, CT – 18% were in accordance with the law of Hardy- Weinberg equilibrium and did not significantly differ (χ2 = 2.204, P = 0.332. There were no significant differences when comparing the allele and genotype frequencies by using risk allele T and C model. In the control group the frequency distribution of genotypes CC – 34%, CT – 51%, TT – 15% did not differ significantly (χ2 = 3.540, P = 0.170 from refractory asthma (CC – 52%, CT – 35%, CT – 13%. The risk analysis for the T allele showed that the frequency of CT+TT genotype in patients with refractory asthma (49% was significantly lower (OR = 0.467, CI = [0.240-0.910], χ2 = 5.17, p = 0.023 compere to control (66 %. In turn, the difference of allelic frequencies for the control and patients with persistent asthma did not differ significantly (p = 0.076. The content of antiendotoxin antibody of class A in

    Obstructive lung diseases represent a major health problem worldwide due to their high prevalence associated with elevated socioeconomic costs. Bronchial asthma and chronic obstructive pulmonary disease are chronic obstructive ventilatory disorders with airway inflammation, however they are separate nosological entities based on thedifferent development, diagnostic and therapeutic approaches, and prognostic features. However, these diseases may coexist and can be defined as the coexistence of increased variability of airflow in a patient with incompletely reversible airway obstruction. This phenotype is called asthma - chronic obstructive pulmonary disease overlap syndrome. The syndrome is a clinical and scientific challenge as the majority of these patients have been excluded from the clinical and pharmacological trials, thus well-defined clinical characteristics and therapeutic approaches are lacking. The aim of this review is to summarize the currently available literature focusing on pathophysiological and clinical features, and discuss possible therapeutic approaches of patients with asthma - chronic obstructive pulmonary disease overlap syndrome.

    Despite comprehensive guidelines established by the European Global Initiative for Asthma and the U.S. National Asthma Education and Prevention Program on the diagnosis and management of asthma, its mortality in older adults continues to rise. Diagnostic and therapeutic problems contribute to older patients being inadequately treated. The diagnosis of asthma rests on the history and characteristic pulmonary function testing (PFT) with the demonstration of reversible airway obstruction, but there are unique problems in performing this test in older patients and in its interpretation. This review aims to address the difficulties in performing and interpreting PFT in older patients because of the effects of age-related changes in lung function on respiratory physiology. The concept of "airway remodeling" resulting in "fixed obstructive" PFT and the relevance of atopy in older people with asthma are assessed. There are certain therapeutic issues unique to older patients with asthma, including the increased probability of adverse effects in the setting of multiple comorbidities and issues surrounding effective drug delivery. The use of beta 2-agonist, anticholinergic, corticosteroid, and anti-immunoglobulin E treatments are discussed in the context of these therapeutic issues.

    Background Asthma is one of the most prevalent chronic conditions in the United Sates, yet despite the existence of national guidelines, nearly three fourths of patients with asthma do not have adequate control and clinical adherence to guidelines is low. While there are many reasons for this, physician inertia with respect to treatment change is partly to blame. Research suggests that patients who ask for specific tests and treatments are more likely to receive them. Objectives This study investigated the impact and experience of using an interactive patient website designed to give patients individual feedback about their condition and to suggest tailored questions for patients to ask their physician. The website was designed to be used prior to a physician visit, to increase the likelihood that patients would receive recommended tests and treatments. Methods A total of 37 adult patients with asthma participated in semi-structured telephone interviews aimed at eliciting information about their experiences with the website. Transcripts were coded using qualitative data analysis techniques and software. Themes were developed from subsets of codes generated through the analysis. In addition, 26 physicians were surveyed regarding their impressions of the website. Results Opportunities exist for improving website feedback, although the majority of both patient and physician respondents held favorable opinions about the site. Two major themes emerged regarding patients’ experiences with the website. First, many patients who used the website had a positive shift in their attitudes regarding interactions with their physicians. Second, use of the website prompted patients to become more actively involved in their asthma care. No patient reported any negative experiences as a result of using the website. Physicians rated the website positively. Conclusions Patients perceived that the interactive website intervention improved communication and interaction with their

    In humans, T cells expressing the CD161 molecule NKR-P1A constitute around 20% of the circulating CD3(+) cells and are potentially immunoregulatory in several diseases. Their role in asthma is not well known, but they could participate in asthma attacks. To determinate whether activation of CD161(+) T cells and their cytokine production correlate with clinical status of asthma, we analysed blood samples from asthma attack patients (AAP) and stable asthma patients (SAP) in comparison with healthy non-atopic controls (HC). There was a significant higher baseline expression of CD69 on T cells from AAP and the difference was more notorious on CD161(+) T cells; upregulation of CD69 was observed on both CD161(-) and CD161(+) T cells driven by Dermatophagoides pteronyssinus crude extract, whereas polyclonal stimulation with phorbol 12-myristate 13-acetate plus ionomycin predominantly induced IFN-gamma but no IL-4, IL-5 and IL-13 by CD161(+) T cells in all groups; upon polyclonal stimulation, there were more CD161(+) T cells producing IFN-gamma and less CD161(-) T cells producing this cytokine, contrasting with the opposite results observed in SAP and HC groups. Our results indicate that, during asthma attack, CD161(+) T cells are activated and are able to produce predominantly IFN-gamma but no Th2 cytokines. We hypothesize that during an asthma attack, IFN-gamma produced by CD161(+) T cells could help to reestablish the Th1/Th2 equilibrium. These observations may contribute to the understanding of the immune mechanisms involved in asthma attacks.

    The aim of our study is to analyse hospital readmissions due to asthma, as well as the factors associated with their increase. We carried out a retrospective study including all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010. The data were gathered by two members of the research team, by reviewing the clinical records. The first hospital admission of each patient was included for this study. An early readmission (ER) was defined as that which occurred in the following 15 days after hospital discharge and late readmission (LR) to that occurring from 16 days after discharge. This study included 2166 hospital admissions and 1316 patients, with a mean age of 62.6 years. Of the 1316 patients analysed, 36 (2.7%) had one ER and 313 (23.8%) one LR. The only factor independently associated with a higher probability of an ER was poor lung function. A higher probability of LR was associated with a greater severity of the asthma (OR: 17.8, for severe asthma versus intermittent asthma), to have had any hospital admission in the previous year (OR: 3.5) and the use of a combination of ICS-LABA as maintenance treatment. About 25% of the patients in our area admitted to hospital due to asthma exacerbation had repeat episodes of hospitalisation.
