Adverse respiratory effects from personal smoking include worse asthma control and a predisposition to lower lung function and chronic obstructive pulmonary disease. Some data suggest that individuals with asthma are more likely than their non-asthmatic peers to smoke regularly at an earlier age. While quit attempts can be more frequent in smokers with asthma, they are also of shorter duration than in non-asthmatics. Considering these asthma-specific characteristics is important in order to individualize smoking cessation strategies. In particular, asthma-specific information such as “lung age” should be provided and longer-term follow-up is advised. Promising emerging strategies include reminders by cellular phone and web-based interventions using consumer health informatics. For adolescents, training older peers to deliver asthma education is another promising strategy. For smokers who are hospitalized for asthma, inpatient nicotine replacement therapy and counseling are a priority. Overall, improving smoking cessation rates in smokers with asthma may rely on a more personalized approach, with the potential for substantial health benefits to individuals and the population at large

    agreement between the healthcare professional and patient on a predefined target regarding asthma control and a treatment plan to achieve this. Summary Optimum review of asthma is essential to improve control. A key priority is the development of simple and effective tools for identifying poor control for individual patients coupled with a tailored approach to treatment to enable patients to set and achieve realistic goals for asthma control.

    Full Text Available This study aimed to evaluate effect of proton pump inhibitor (esomeprazole on asthma symptoms, use of inhaled bronchodilator and peak expiratory flow rate (PEFR in moderate persistent asthma with gastroesofageal refluks disease (GERD. This randomized single blind, controlled clinical trial study was conducted at Persahabatan Hospital, Jakarta from July 2004 until October 2005. Samples were moderate persistent asthma patients with GERD. GERD is diagnosed GERD symptoms and proof of oesophagitis from endoscopy and or histapatologic examination from oesophagus biopsy. Phase 1:2 week run-in period patient received inhaled budesonide 2x200 ug/day. Phase 2: patient randomised to receive inhaled budesonide 2 x 400 ug/day with esomeprazole 40 mg/day or without esomeprazole (control group for 8 weeks. Phase 3: 4 week wash out period, patient receive inhaled budesonide 2 x 200 ug/day. Diary cards were assessed at run-in periode, after treatment 4 weeks, 8 weeks and wash out. There were 32 patients (23 female and 9 male completed the study. Mean total asthma symptoms score daily were significantly decreased on esomeprazole vs without esomeprazole after 8 weeks (-2.29 vs -0.90; p < 0.05.

    Full Text Available Nicola Scichilone, Adele Contino, Giovanni Battista Figlioli, Giuseppe Paglino, Vincenzo BelliaDipartimento di Medicina, Pneumologia, Fisiologia e Nutrizione Umana (DIMPEFINU, University of Palermo, Palermo, ItalyAbstract: Asthma is a chronic inflammatory disorder of the airways that requires long-term treatment, the goal of which is to control clinical symptoms for extended periods with the least possible amount of drugs. International guidelines recommend the addition of an inhaled long-acting beta2-agonist (LABA to a low- to medium-dose inhaled corticosteroid (ICS when low doses of ICS fail to control asthma symptoms. The fixed combined administration of ICS/LABA improves patient compliance, reducing the risk of therapy discontinuation. The relative deposition pattern of the inhaled drug to the target site is the result of a complex interaction between the device used, the aerosol formulation and the patient’s adherence to therapy. Different inhalation devices have been introduced in clinical practice over time. The new hydrofluoroalkane (HFA solution aerosols allow for the particle size to be modified, thus leading to deeper penetration of the medication into the lung. The Modulite® technology allows for the manipulation of inhaled HFA-based solution formulations, such as the fixed beclomethasone/formoterol combination, resulting in a uniform treatment of inflammation and bronchoconstriction. The success of any anti-asthmatic treatment depends on the choice of the correct device and the adherence to therapy.Keywords: asthma, therapy, inhalers, compliance

    Full Text Available Twenty-five patients with intractable asthma had swimming training in a hot spring pool for 3 months. The subjects were divided into three groups according to their clinical symptoms and ages. Changes of ventilatory function during swimming training were observed in in each group. The ventilatory function test revealed that free swimming training in a hot spring pool for 30 min did not induce bronchoconstriction in any of the groups. The values of ventilatory parameters such as FEV 1.0%, %PEFR, %V50 and %V25 were improved after the 3-month swimming training. The improvement of ventilatory parameters, especially %MMF, %V50 and %V25, by the training was most remarkable in the type II asthma group. The percent increase in %MMF, %V50 and %V25 was highest in patients more than 61 years of age, and higher in patients aged 40 to 60 years than in younger patients.

    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.

    With appropriate management, children with asthma should expect few symptoms, no limits on activity, rare exacerbations, and normal lung function. Appropriate education of parents and other caregivers of children with asthma has clearly been shown to help achieve these goals. Although recommended in asthma guidelines, providing written asthma action plans does not improve outcomes beyond asthma education alone.

    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 ...

    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.

    Sexual quality of life was examined in 55 outpatients with chronic obstructive pulmonary disease (COPD) and asthma, using disease-specific questionnaires. Compared to an age- and sex-matched norm group, male patients with COPD reported a significantly lower sexual quality of life on all dimensions of the questionnaire. Female patients with COPD reported a lower frequency of sexual intimacy and lower sexual quality of life overall. Patients with asthma reported sexual quality-of-life scores that were somewhat better than COPD patients but worse than the healthy control group. Patients reported that they did not discuss sexual quality-of-life issues with their physician. Sexuality needs to be discussed by the health care provider in the consultation in order to improve quality of life of patients with chronic respiratory disorders. PMID:17996435

    2011-04-01

    Uncontrolled asthma is an enormous burden in terms of the propensity to reach asthma control in the future, direct and indirect costs, and health-related quality of life. The complex pathophysiology, treatment, and triggers of asthma warrant a unified, yet targeted, approach to care. No single factor is fully responsible for poor control. Complicating the problem of asthma control is adherence to long-term controller medications. The National Asthma Education and Prevention Program (NAEPP) established several key points for asthma control, and developed classifications for asthma control and recommended actions for treatment. All parties involved in the management of asthma, including physicians, pharmacists, nurses, patients, family members, and insurance companies, need to be aware of the NAEPP guidelines. To determine if the goals of asthma therapy are being met, assessment of asthma outcomes is necessary. Unfortunately, some measures may get overlooked, and patient-reported outcomes (as assessed by the validated control instruments) are not often collected during routine examinations. The Healthcare Effectiveness Data and Information Set measure for asthma may be used to quantify asthma care, but there is evidence that it does not fully capture the goals of asthma management. Most well-designed, education-based interventions are considered good value for money, but it can be difficult to put into practice such policy interventions. An optimal managed care plan will adhere to known evidence-based guidelines, can measure outcomes, is targeted to the patient's risk and impairment, and can adapt to changes in our understanding of asthma and its treatment.

    Asthma is the most commonly encountered chronic disease in children. Periodic assessment of asthma severity and control is an integral part of asthma management, but patients with uncontrolled asthma don't always schedule routine asthma care visits. The aim of this project was to improve asthma control and severity screening in a primary care setting by using a validated tool for all visits for patients with a diagnosis of asthma aged 4-21 years. Our QI team developed a protocol to administer the Asthma Control Test (TM), a validated questionnaire to assess asthma control. The stakeholders involved were the physicians, nursing staff, and the Health Information Team (HIT). All patients who had a prior diagnosis of asthma or with an asthma medication in their chart, who presented for any clinical visit including asthma were administered ACT. The staff scored the ACT and included the form in the encounter sheet so that the physicians can review the scores, address the asthma control, severity, and document in the chart. The number of patients whose asthma control was assessed improved from 10% per year to 85% after the three PDSA cycles. Administration of the tool did not impact the flow of the patients in a busy primary care practice. Screening asthma severity and control for patients diagnosed with asthma with a validated questionnaire when presenting for any chief complaint including asthma will help the provider address the severity and control of asthma symptoms in a timely manner and would potentially help prevent unwanted emergency department or urgent care usage.

    2003-11-01

    Despite an abundance of scientific evidence supporting the use of guidelines, adherence to asthma practice guidelines by physicians generally is low, regardless of provider and patient characteristics. As a result, scientific information, obtained with great effort and at huge expense, is not being translated into clinical practice. To remedy this, we developed a disease management program that emphasizes alteration of provider behavior using operant conditioning. We did this by placing asthma educators in private offices for up to 8 weeks. The educators used a combination of problem-based learning, role modeling, and operant conditioning with positive reinforcement to affect behavior change. As a result of these behavior changes, by the end of 8 weeks the cost to treat asthma patients decreased, despite an increase in the cost of medications. We concluded that behavior-oriented programs targeted at provider offices can lead to improved asthma care while reducing costs. PMID:14531969

    2015-01-01

    Asthma remains one of the most common diseases worldwide and results in significant societal health care costs and in morbidity and mortality to those afflicted. Despite currently available medications, 5-10% of patients with asthma have severe disease with debilitating symptoms and/or life-threatening exacerbations. Bronchial thermoplasty is a device-based therapy with proven efficacy in this subgroup of patients. Thus far, bronchial thermoplasty has been shown to reduce exacerbations and to improve important measures of asthma control. The purpose of this article is to review the pathophysiology of severe asthma, including the role of airway smooth muscle cells and the procedural aspects of bronchial thermoplasty, and to review the evidence behind this important therapy.

    Full Text Available Abstract Background In the management of asthma, features of care important to patients may not be fully appreciated. This study quantifies the importance of different features of asthma management from the patient perspective. This may assist in the development of personalised management strategies. Methods We used the technique of discrete choice experiment (DCE. Patients over 18 years of age with asthma, prescribed and taking medicine at step 3 of the UK guidelines were recruited from 15 general (family practices in three areas of the UK. 147 evaluable questionnaires were returned from a total of 348 sent out. The outcome measures were the relative importance to patients of features of asthma management and the impact of changes in asthma management, as measured by utility shift between the features tested. Results The largest shift in mean utility values was recorded in "number of inhalers" and "use of inhaled steroid". Use of a personal asthma action plan was ranked next highest. Conclusion This study suggests that adults with moderate or severe asthma would trade some improvements in symptom relief in favour of, for example, simpler treatment regimens that use as few inhalers as possible and a lower dose of inhaled steroid.

RESULTS: Among the 400 respondents, asthma was controlled in 37 (9.3%, partially controlled in 226 (56.5%, and uncontrolled in 137 (34.2%. The numbers of patients with uncontrolled or partially controlled asthma who visited the emergency room, who were hospitalized, and who missed school/work were higher than were those of patients with controlled asthma (p = 0.001, p = 0.05, and p = 0.01, respectively. Among those with uncontrolled asthma, the impact of the disease on activities of daily living, sleep, social activities, and normal physical exertion was greater than it was among those with controlled or partially controlled asthma (p < 0.001. CONCLUSIONS: In Brazil, asthma treatment should be monitored more closely in order to increase treatment adherence and, consequently, the level of asthma control, which can improve patient quality of life and minimize the negative impact of the disease.

    Full Text Available Introduction: Asthma is characterized by airway inflammation, airway hyper responsiveness, and reversible airflow limitation. The prevalence of the disease has increased over 2 decades to approximately 5 to 10% of the population. The presence of nasal polyposis in asthma patients is associated with increase in asthma severity. We attempted to determine the efficacy of endoscopic sinus surgery in patients with asthma and nasal polyposis. Materials and Methods: We performed a prospective, cross-sectional study from 2001 until 2006. This study included 50 patients with severe persistent asthma and nasal polyposis. The severity of asthma (in NHLBI and NAPP and FEV1 before and after endoscopic nasal polypectomy was recorded. We used paired simple T test for comparation of data mean.The gathered data were analyzed with SPSS software. Results: In this study, median ages are 32.5 ± 14.3  years. Male to female is 2.3 to 1. All of patients have severe persistent asthma and nasal polyposis. From 50 patients with asthma and nasal polyposis, in 38 cases asthma severity and FEV1 were improved. (mean of  FEV1 before endoscopic  sinus polypectomy = 1.68 L ,  mean of FEV1 after endoscopic sinus polypectomy = 2.52 L.  Conclusion: Opening of upper airway and improvement of breathing through sinus endoscopy induce betterment of asthma severity, though the possibility of nasal polyposis should be investigated and treatment with endoscopic sinus surgery planned accordingly.

    Adherence to daily inhaled corticosteroid therapy is a key determinant of asthma control. Therefore, improving adherence to inhaled corticosteroids is the most effective method through which healthcare providers can help children with uncontrolled asthma. However, identifying non-adherent patients is difficult, and electronic monitoring is the only reliable method to assess adherence. (Non-)adherence is a complex behavioural process influenced by many interacting factors. Intentional barriers to adherence are common; driven by illness perceptions and medication beliefs, patients and parents deliberately choose not to follow the doctor's recommendations. Common non-intentional barriers are related to family routines, child-raising issues, and to social issues such as poverty. Effective interventions improving adherence are complex, because they take intentional and non-intentional barriers to adherence into account. There is evidence that comprehensive, guideline-based asthma self-management programmes can be successful, with excellent adherence and good asthma control. Patient-centred care focused on healthcare provider-patient/parent collaboration is the key factor determining the success of guided self-management programmes. Such care should focus on shared decision-making as this has been shown to improve adherence and healthcare outcomes. Current asthma care falls short because many physicians fail to adhere to asthma guidelines in their diagnostic approach and therapeutic prescriptions, and because of the lack of application of patient-centred health care. Increased awareness of the importance of patient-centred communication and increased training in patient-centred communication skills of undergraduates and experienced attending physicians are needed to improve adherence to daily controller therapy and asthma control in children with asthma.

    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.

    Background So far, in China, there has been no effective or easy procedure to define the control of asthma. This study assesses the validity of Asthma Control Test in Chinese patients.Methods Three questionnaires (Asthma Control Test, Asthma Control Questionnaire and the 30 second asthma test)were administered to 305 asthma patients from 10 teaching hospitals across China. Spirometry was also used. Asthma specialists rated the control of asthma according to patients' symptoms, medications and forced expiratory volume in first second. The patients were divided into noncontrolled group and controlled group according to the specialists' rating.Reliability, empirical validity and screening accuracy were conducted for Asthma Control Test scores. Screening accuracy was compared among 3 questionnaires. The patients' self rating and the specialists' rating were also compared.Results The internal consistency reliability of the 5-item Asthma Control Test was 0.854. The correlation coefficient between Asthma Control Test and the specialists' rating was 0.729, which was higher than other instruments. Asthma Control Test scores discriminated between groups of patients differing in the percent predicted forced expiratory volume in first second (F=26.06, P<0.0001), the specialists' rating of asthma control (F=88.24, P<0.0001) and the Asthma Control Questionnaire scores (F=250.57, P<0.0001). Asthma Control Test showed no significant difference with Asthma Control Questionnaire in the percent correctly classified, while the percent correctly classified by Asthma Control Test was much higher than 30 second asthma test. The patients' self rating was the same as assessment of the specialists (t=0.65, P=0.516).Conclusion The Asthma Control Test is an effective and practicable method for assessing asthma control in China.

    Full Text Available Objective. We aimed to identify key enablers of physician prescription of a long-term controller in patients with persistent asthma. Methods. We conducted a mailed survey of randomly selected Quebec physicians. We sent a 102-item questionnaire, seeking reported management regarding one of 4 clinical vignettes of a poorly controlled adult or child and endorsement of enablers to prescribe long-term controllers. Results. With a 56% participation rate, 421 physicians participated. Most (86% would prescribe a long-term controller (predominantly inhaled corticosteroids, ICS to the patient in their clinical vignette. Determinants of intention were the recognition of persistent symptoms (OR 2.67, goal of achieving long-term control (OR 5.31, and high comfort level in initiating long-term ICS (OR 2.33. Decision tools, pharmacy reports, reminders, and specific training were strongly endorsed by ≥60% physicians to support optimal management. Physicians strongly endorsed asthma education, lung function testing, specialist opinion, accessible asthma clinic, and paramedical healthcare professionals to guide patients, as enablers to improve patient adherence to and physicians’ comfort with long-term ICS. Interpretation. Tools and training to improve physician knowledge, skills, and perception towards long-term ICS and resources that increase patient adherence and physician comfort to facilitate long-term ICS prescription should be considered as targets for implementation.

    Good adherence to inhaled corticosteroid (ICS) therapy is essential for effective asthma control. The factors affecting ICS therapy adherence vary among individuals and countries. As few data on adherence have been reported in Korea, the factors influencing such adherence, and the clinical implications thereof, were evaluated in Korean asthma patients. A total of 185 asthma patients who had taken ICS regularly for over 1 year were randomly selected from the recently established domestic adult asthma cohort, COREA (Cohort for Reality and Evolution of Adult Asthma Korea). To obtain adherence to ICS, both prescription refill adherence and self-reported adherence over 1 year (these are objective and subjective measurements respectively) were assessed without any interventions that might affect patients' adherence to ICS. Patients' information such as age, sex, smoking history and number of medication taken, was collected. Assessment of asthma severity, pulmonary function tests, and asthma symptom score were performed to evaluate the possible clinical implication of adherence to ICS. Approximately half of the patients (50.9%) showed less than 80% of prescription refill adherence. There was a considerable discrepancy between prescription refill adherence and self-reported adherence especially in the patients whose refill adherence was under than 50%. Younger asthma patients showed lower adherence to ICS than did older (> or = 60 years old) patients. Higher asthma severity was significantly associated with lower refill adherence to ICS. However, asthma symptom scores and forced expiratory volume in 1 second (FEV(1)) values were not directly related with refill adherence. To improve asthma control in Korea, enhancement of adherence to ICS is critical: our findings emphasize the need to use objective measurements when adherence to asthma medication is to be assessed in clinical practice.

    2016-01-01

    Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) often have coexisting asthma under the concept of "United Airway Disease", being the combination of both diseases, which is one of the most challenging phenotypes to treat. Although clinicians have recognized this difficult-to-treat phenotype for many years, it remained poorly characterized. There is increasing epidemiological evidence linking chronic rhinosinusitis and asthma, but a good understanding of the pathophysiology and the combined management is still lacking. Bronchial asthma is more prevalent in patients who suffer chronic rhinosinusitis, while asthmatic patients have a greater prevalence of CRSwNP than patients without asthma. The effect of CRSwNP treatment, whether medical or surgical, in asthma is today less controversial after some studies have shown improvement of asthma after medical and/or surgical treatment of CRSwNP. However, direct comparisons between surgical and medical treatments are limited. Further randomized clinical trials are, however, still needed to better understand the management when both asthma and CRSwNP occur together. This review aims at summarizing the prevalence, impact, and management challenges regarding both asthma and CRSwNP. PMID:27042129

    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.

    Full Text Available INTRODUCTION: Asthma is an inflammatory, reversible and progressive disease with episodes of exacerbations. Asthma is now considered as single airway disease and hence comprehensive diagnosis, treatment and follow-up of upper and lower respiratory tract is essential. Both the Nasal and Bronchial mucosa are the elements of united airway disease and Eosinophils measured from this mucosa can be an indirect marker of Airway inflammation in asthma. Eosinophil infiltration is hallmark feature of pathogenesis of asthma which is the trigger for the chronic airway inflammation and these are raised in acute exacerbations. Hence assessing Eosinophil is evidence of serological marker for Airway inflammation (AI. Nasal Smear Eosinophils (NSE is used in asthma with Allergic Rhinitis (AR. This study Using Definition of GINA explores the utility of NSE as marker for management of Asthma. METHODS: In this study 100 patients diagnosed with bronchial asthma attending the outpatient department in KIMS were studied. The severity of asthma was assessed as per FEV1 classification- Adapted from 2007 NHLBI Guidelines for the diagnosis and treatment of Asthma Expert panel Report 3. The Statistical analysis was done with SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1.software. RESULTS: Asthma was more common in Females in this study with M: F ratio of 1.04 and Allergic Rhinitis was found in 55% of Asthmatics. Nasal Eosinophilia was seen in 44% in asthmatic group and 49% in Asthma with Allergic Rhinitis.

    Full Text Available Difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. Mediastinal masses are not common findings, but are important variables. Bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. We present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchogenic cyst was detected in this patient. The patient had history of asthma since she was eight months old. She had a history of several asthma attacks which had partly responded to asthma management. During the last episodes of asthma attacks, she was hospitalized in Pediatric Intensive Care Unit. Imaging studies showed a 4×3 cm mass in the posterior part of the thoracic cavity that had led to tracheal narrowing was found for which the patient underwent thoracotomy and in surgical exploration a cyst that had compressed the thoracic trachea. Pathological examination of the cyst revealed a bronchogenic cyst. Bronchogenic cyst is an uncommon developmental abnormality but in a patient with obstructive pattern of airways it should be considered in differential diagnosis of asthma, especially if the asthma management is not successful.

    2006-01-01

    @@ Asthma can be generally divided into the onset stage and the remission stage. At the onset stage, the symptoms should be under control. Patients with pulmonary infection should be treated with anti-infective drug. During this stage, the patient should not be tonified except those with general qi deficiency. For patients with general qi deficiency,they can be slightly nourished to strengthen the body resistance and eliminate pathogenic factors. At the remission stage, patient may have deficiency of the lung, spleen and kidney. Those who have deficiency of the lung and spleen have a mild illness while those with deficiency of the kidney have a severe illness.Therefore, at the remission stage, Chinese drugs can be used to strengthen the body resistance, improve the constitution and balance the internal organs, qi,blood, yin and yang so as to reduce further attacks of asthma. According to the degree of deficiency of the lung, spleen and kidney, syndrome differentiation can be carried out in an attempt to provide the patients with proper nourishing and invigorating food or drugs.

    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)

    Disenfranchised ethnic minority communities in the urban United States experience a high burden of asthma. Conventional office-based patient education often is insufficient to promote proper asthma management and coping practices responsive to minority patients' environments. This paper explores existing and alternative asthma information and education sources in three urban minority communities in western New York State to help design other practical educational interventions. Four focus groups (n = 59) and four town hall meetings (n = 109) were conducted in one Hispanic and two black communities. Focus groups included adult asthmatics or caretakers of asthmatics, and town meetings were open to all residents. A critical theory perspective informed the study. Asthma information and education sources, perceptions of asthma and ways of coping were elicited through semi-structured interviews. Data analysis followed a theory-driven immersion-crystallization approach. Several asthma education and information resources from the health care system, media, public institutions and communities were identified. Intervention recommendations highlighted asthma workshops that recognize participants as teachers and learners, offer social support, promote advocacy, are culturally appropriate and community-based and include health care professionals. Community-based, group health education couched on people's experiences and societal conditions offers unique opportunities for patient asthma care empowerment in minority urban communities.

    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

Although clinicians have recognized this difficult-to-treat phenotype for many years, it remained poorly characterized. There is increasing epidemiological evidence linking chronic rhinosinusitis and asthma, but a good understanding of the pathophysiology and the combined management is still lacking. Bronchial asthma is more prevalent in patients who suffer chronic rhinosinusitis, while asthmatic patients have a greater prevalence of CRSwNP than patients without asthma. The effect of CRSwNP treatment, whether medical or surgical, in asthma is today less controversial after some studies have shown improvement of asthma after medical and/or surgical treatment of CRSwNP. However, direct comparisons between surgical and medical treatments are limited. Further randomized clinical trials are, however, still needed to better understand the management when both asthma and CRSwNP occur together. This review aims at summarizing the prevalence, impact, and management challenges regarding both asthma and CRSwNP.

    Full Text Available Asthma is chronic inflammatory, airway hyper-responsiveness, reversible disorder which occurs at any age, and requires special attention towards management of drug therapy. There is lack of patients awareness in having the complete knowledge about the disease, attitude towards disease management, medication adherence behavior and treatment outcomes. The objective of the present study was to assess the knowledge and attitude of the patients towards their disease in improving the outcome in asthma patients. MATERIALS AND METHODS: This was a prospective, observational, questionnaire and hospital based study in a tertiary care teaching hospital at two different centers for a period of 12 months. The data was collected by face to face interview of outpatients and inpatients of Pulmonary Medicine and Internal Medicine departments by administering the questionnaires for the assessment of knowledge, attitude and adherence towards the bronchial asthma disease. RESULTS: A total of 160 patients with confirmed diagnosis of bronchial asthma were included in this study, out of which male patients were 87(54.5% and female patients 73(45.5%. On an average, each patient had already visited 3 doctors prior to coming to us. Out of 160 patients, 68% patients were ignorant regarding disease etiology, and another 54% patients were reluctant to accept the diagnosis of asthma. About 88% had the knowledge that lungs are affected by this disease. Another 44% opined that the medicines used for asthma can cause airways narrowing on long turn. Attitude of the patients varied greatly among the patients in this study. Regarding precipitating factors, 46% parents attributed the disease exacerbations due to multiple causes. The compliance rate in using inhalers for asthma was low (60%, and many patients stopped medications in spite of proper advice regarding inhalational therapy. CONCLUSION: This study concludes that the assessment of knowledge and attitude towards the disease

    Asthma is a common heterogeneous disease with a complex pathophysiology that carries a significant mortality rate and high morbidity. Current therapies based on inhaled corticosteroids and long-acting β-agonists remain effective in a large proportion of patients with asthma, but ~10% (considered to have 'severe asthma') do not respond to these treatments even at high doses or with the use of oral corticosteroids. Analytical clustering methods have revealed phenotypes that include dependence on high-dose corticosteroid treatment, severe airflow obstruction and recurrent exacerbations associated with an allergic background and late onset of disease. One severe phenotype is eosinophilic inflammation-predominant asthma, with late-onset disease, rhinosinusitis, aspirin sensitivity and exacerbations. Blood and sputum eosinophilia have been used to distinguish patients with high Th2 inflammation and to predict therapeutic response to treatments targeted towards Th2-associated cytokines. New therapies in the form of humanized antibodies against Th2 targets, such as anti-IgE, anti-IL4Rα, anti-IL-5 and anti-IL-13 antibodies, have shown encouraging results in terms of reduction in exacerbations and improvement in airflow in patients with a 'Th2-high' expression profile and blood eosinophilia. Research efforts are now focusing on elucidating the phenotypes underlying the non-Th2-high (or Th2-low) group, which constitutes ~50% of severe asthma cases. There is an increasing need to use biomarkers to indicate the group of patients who will respond to a specifically targeted treatment. The use of improved tools to measure activity of disease, a better definition of severe asthma and the delineation of inflammatory pathways with omics analyses using computational tools, will lead to better-defined phenotypes for specific therapies.

    Care for patients with asthma requires prompt and effective decision-making abilities. Many nursing students report a lack of preparedness and competence with respect to their ability to perform nursing duties. Simulation-based learning has been developed as a potential solution to this problem. Moreover, the simulation scenario with an evaluation checklist offers a reliable evaluation strategy for the education and training of clinical decision-making skills among nursing students. The simulation scenario and evaluation checklist developed in this study offer a means to improve patient safety during asthma care in the emergency care unit, as well as to improve nursing students' problem-solving competencies and communication with patients with asthma.

    Asthma is a clinical problem with social, psychological, and economic burdens. To improve patient disease management and quality of life (QOL), different education programs have been developed. The purpose of this study is to adapt and implement a community-based educational program for patients with asthma. A prospective, randomized, controlled trial was performed. Fifty individuals with mild asthma (aged 18-40 years) that have been attending pharmacies were included in the sample. The duration of the disease was 9 +/- 4.21 years. A 4-month study was conducted on essence of asthma and factors that can intensify it; nourishing facts, allergens, and physical activities; self-management and use of tobacco; and pharmacotherapy, inhalation technique, and possible adverse drug reactions. Patient's health-related QOL was assessed in the beginning and at the end of the survey. Parameters assessed during the four stages of the program were patients' peak expiratory flow (PEF); inhaler technique; severe asthma symptoms, including breathlessness, hospitalization rates, frequency of urgent medical aid calls, and frequency of general practitioner visits; compliance with therapy; and satisfaction with pharmacy services. Health-related QOL of the intervention patients was improved at 4 months and there was improvement in the PEF rate, decrease in patients' breathlessness and wheezing rate, decrease in the reported hospitalizations rate because of the disease, decrease in the physician's visits, and increase in satisfaction with pharmacist-provided information. The positive results from the educational approach show a potential to decrease asthma disease complications and show a positive impact on patients' inhaler technique, patients' opinions about the pharmacy services, and information obtained.

    Full Text Available Objective: To evaluate the impact of asthma on patients in Brazil, by age group (12-17 years, 18-40 years, and ≥ 41 years. Methods: 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. Results: 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 < 0.001; "Have you discontinued your asthma relief or control medication in the last 12 months?" (p = 0.008. In addition, 30.2% of the patients in the 12- to 17-year 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. Conclusions: 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.

    The management and treatment of adult asthma has been associated with utilization of health services. Objectives: First, to investigate the likelihood of health service utilization, including primary care, emergency department, and hospital stays, among persons diagnosed with an asthma condition relative to those that do not have an asthma condition. Second, to examine the likelihood of poor physical health among asthma respondents relative to those that do not have an asthma condition. Third, to demonstrate that these relationships vary with frequency of utilization. Fourth, to discuss the magnitude of differences in frequent utilization between asthma and non-asthma respondents. Data Source: Data is derived from a random, stratified sampling of Hampton Roads adults, 18 years and older (n = 1678). Study Design: Study participants are interviewed to identify asthma diagnosis, access to primary care, frequency of emergency department utilization, hospital admissions, and days of poor physical health. Odds-ratios establish relationships with the covariates on the outcome variable. Findings: Those with asthma are found more likely (OR 1.50, 95% CI 1.05–2.15) to report poor physical health relative to non-asthma study participants. Further, asthma respondents are found more likely (OR 4.23, 95% CI 1.56–11.69) to frequently utilize primary care that may be associated with the management of the condition and are also more likely to utilize treatment services, such as the emergency department (OR 1.87, 95% CI 1.32–2.65) and hospitalization (OR 2.21, 95% CI 1.39–3.50), associated with acute and episodic care. Further, it is a novel finding that these likelihoods increase with frequency of utilization for emergency department visits and hospital stays. Conclusion: Continuity in care and better management of the diseases may result in less demand for emergency department services and hospitalization. Health care systems need to recognize that asthma patients are

Methods Were reviewed the medical records of 400 patients with gastroesophageal reflux disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and identified 30 patients with extra-esophageal symptoms related to asthma. The variables considered were: gender, age, gastroesophageal symptoms (heartburn, acid reflux and dysphagia), time of reflux disease, treatment with proton pump inhibitor, use of specific medications, treatment and evolution, number of attacks and degree of esophagitis. Data were subjected to statistical analysis, comparing the pre- and post-surgical findings. Results The comparative analysis before surgery (T1) and six months after surgery (T2) showed a significant reduction on heartburn and reflux symptoms. Apart from that, there was a significant difference between the patients with daily crises of asthma (T1 versus T2, 45.83% to 16.67%, p=0.0002) and continuous crises (T1, 41.67% versus T2, 8.33%, p=0.0002). Conclusion Laparoscopic Nissen fundoplication was effective in improving symptoms that are typical of reflux disease and clinical manifestations of asthma. PMID:25004284

    The "bronchial remodeling" specific for the asthmatic disease consists in irreversible changes of the bronchial wall, including glandular and smooth muscle fibers hyperplasia and÷or hypertrophy, goblet cells hyperplasia, and thickening of basement membrane (BM). We aimed to analyze the BM thickness in asthma patients, in order to validate the relationship between its changes and the disease severity defined in agreement with the Global Initiative for Asthma (GINA) criteria. The study group has been formed of 38 patients with different degrees of severity of asthma established by spirometry using Forced Expiratory Volume in one second (FEV1), and two patients without asthma symptoms as controls. The specimens harvested by fibrobronchoscopy have been processed by paraffin embedding followed by Hematoxylin-Eosin (HE) and Periodic Acid-Schiff (PAS) staining. For each case, the BM measurement has been realized by a "point-by-point" method. Statistical analysis has been performed using SPSS 17 software, by applying non-parametric correlation tests. The quantitative assessment revealed a progressive increase in BM thickness during the course of the disease, from a mean value of 11.2 μm in stage 1 to that of 15.6 μm in stage 4. Even if this process has been noticed starting with the first stage of asthma, the differences in the BM size were statistically significant only for stages 1 and 3 (p=0.047), stages 1 and 4 (p=0.000), stages 2 and 3 (p=0.000), and stages 3 and 4 (p=0.000). Spearman's test has shown an opposite correlation between the BM thickness and asthma severity defined by FEV1 values (r=-0.86, pasthma and continues in a progressive modality, the BM thickening being correlated with the disease severity. Thus, we support the concept of biological consequences of BM thickening in asthma pathogenesis, a mechanism still incompletely deciphered. PMID:27151696

    Full Text Available Background: While origin of Asthma is allergy and infection, mental stresses can also indicate asthma attacks. Most people with asthma argue that the reason of asthma attacks is mental- psychological problems such as stress. Aim & objective: Asthma is a chronic and recurrent disease. High levels of stress in this disease are associated with increased hospitalization and mortality, so this research aims to use cognitive behavioral therapy in order to control stress among patients with Asthma. Method/Study Design: Present study is a field and Quasi-experimental whose statistical society includes all patients with Asthma who have referred to Khatamol-Anbia Hospital for treatment. A total of 48 individuals were tested and controlled by purposive sampling procedure. 8 individual CBT sessions were conducted in experimental group during intervention period then the number of asthma attacks in the pre-test and post-test periods was evaluated Results/Finding: After analyzing data with SPSS software, results show that there exists significant difference between experimental and control group in post-test in ACQ, ASES and AQLQ questionnaires which is significant between two groups by a difference of ρ<0.001 but this difference wasn’t significant in pre-test. Conclusion: The results suggest that cognitive behavioral therapy along with conventional treatment in asthma patients can be effective on reduction of asthma attacks. Individual management improvement is based on such behavioral factors as daily scanning on symptoms and adherence to treatment which is affected by Asthma Self-Efficacy (ASE. This issue suggests the trust to ability in performing necessary behaviors on personal management for disease symptoms and prevention of recurrence.

  17. 'Real-life' effectiveness studies of omalizumab in adult patients with severe allergic asthma: systematic review.

    Abraham, I; Alhossan, A; Lee, C S; Kutbi, H; MacDonald, K

    2016-05-01

    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.

    Asthma is a very common disease that can occur at any age. In the UK and in many other countries it is mainly managed in primary care. The published evidence suggests that the key to improving diagnosis and management lies in better training and education rather than in the discovery of new medications. An asthma improvement project managed through the British Lung Foundation is attempting to do this. The project has three pilot sites: two in England supported by the Department of Health and one in Scotland supported by the Scottish Government. If the project is successful it will be rolled out to other health areas within the UK. The results of this project are not yet available. This article highlights the challenges encountered in setting up the project and may well be applicable to other areas in the UK and to other countries where similar healthcare systems exist. The encountered challenges reflect the complex nature of healthcare systems and electronic data capture in primary care. We discuss the differences between general practices in their ability and willingness to support the project, the training and education of their staff on asthma management, governance issues in relation to information technology systems, and the quality of data capture. Virtually all the challenges have now been overcome, but discussing them should ensure that others become aware of them at an early stage should they wish to undertake similar projects in the future.

  1. Pulmonary ventilation and perfusion scintigraphy in patients with bronchial asthma

    International Nuclear Information System (INIS)

    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, %FEV1.0). 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 %FEV1.0. 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)

    Self-contained underwater breathing apparatus (scuba) diving has grown in popularity, with millions of divers enjoying the sport worldwide. This activity presents unique physical and physiological challenges to the respiratory system, raising numerous concerns about individuals with asthma who choose to dive. Asthma had traditionally been a contraindication to recreational diving, although this caveat has been ignored by large numbers of such patients. Herein we review the currently available literature to provide evidence-based evaluation of the risks associated with diving that are posed to asthmatics. Although there is some indication that asthmatics may be at an increased risk of pulmonary barotrauma, the risk seems to be small. Thus, under the right circumstances, patients with asthma can safely participate in recreational diving without any apparent increased risk of an asthma-related event. Decisions on whether or not diving is hazardous must be made on an individual basis and be founded upon an informed decision shared by both patient and physician. PMID:17476937

    Full Text Available Background: Asthma is common chronic disease worldwide. Methylxanthines has been used in the treatment of asthma. The study was undertaken to compare two Methylxanthines theophylline and doxofylline at doses recommended and commonly used in clinical practice in Mild Bronchial Asthma Patients. Methods: Study was conducted in patients of Mild Bronchial Asthma in TB and chest disease department of a medical college hospital. It was randomized, prospective and open label. A total of 107 patients were divided in two group .Group I was administered 400 mg theophylline SR once daily and group II was administered doxofylline 400 mg twice a day orally. Spirometric variables symptom score, and adverse effects were recorded on day 0, 7 and 21 of therapy. Data were compared and analysed using SPSS version 16. Results: Results of the study showed that there was significant improvement in spirometric variables and clinical symptom score compared to pretreatment values after medication in both groups on 7th and 21st days of treatment. But there was no statistically significant difference between improvement in theophylline and doxofylline groups with respect to spirometric variables and symptom score. There was no significant difference in two groups with respect to side effects (p>0.05. Conclusions: It is concluded in Patients of mild Bronchial Asthma Theophylline and doxofylline improve the spirometric and clinical symptoms and doxofylline has no advantage over theophylline in terms of either efficacy or safety on the doses commonly used in current clinical practice.

    In patients with preasthma and bronchial asthma, short-term courses of fasting dietotherapy (FDT) with a 7-day fasting period proved to be effective, as evidenced by clinical-and-functional and laboratory investigations. The incidence rate of viral infections was much lower with short-term courses compared to long-term courses. Too low an effect, if any, with FDT short-term courses can be explained by excess of the patient's body weight. Short-term FDT courses with a 3-day fasting period have been found out to result in a significant decrease in the level of anxiety, as measured by Spilberger Anxiety Inventory. PMID:12145900

    Directory of Open Access Journals (Sweden)

    Yousef A. Taher

    2010-06-01

    Full Text Available Allergic asthma is a disease characterized by persistent allergen-driven airway inflammation, remodeling, and airway hyperresponsiveness. CD4+ T-cells, especially T-helper type 2 cells, play a critical role in orchestrating the disease process through the release of the cytokines IL-4, IL-5, and IL-13. Allergen-specific immunotherapy (SIT is currently the only treatment with a long-term effect via modifying the natural course of allergy by interfering with the underlying immunological mechanisms. However, although SIT is effective in allergic rhinitis and insect venom allergy, in allergic asthma it seldom results in complete alleviation of the symptoms. Improvement of SIT is needed to enhance its efficacy in asthmatic patients. Herein, the immunoregulatory mechanisms underlying the beneficial effects of SIT are discussed with the ultimate aim to improve its treatment efficacy.

    2009-01-01

    This article examines the possibility of traveling to altitude for patients suffering from bronchial asthma. The mountain environment, the adaptations of the respiratory system to high altitude, the underlying patho-physiologies of asthma, and the recommendations for patients, according to altitude, are discussed. In summary, staying at low altitude has a significant beneficial effect for asthmatic patients, due to the reduction of airway inflammation and the lower response to bronchoconstrictor stimuli; for staying at moderate altitude, there is conflicting information and no clinical data; at high altitude, the environment seems beneficial for well-controlled asthmatics, but intense exercise and upper airway infections (frequent during trekking) can be additional risks and should be avoided. Further, in remote areas health facilities are often difficult to reach. PMID:19519226

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

    Background Chronic kidney disease (CKD) is a growing public health problem with well-established risk factors.Other contributing factors,however,remain to be identified.Systemic inflammation in asthma plays a significant role in the development of other diseases.We therefore initiated a study to assess whether the growing prevalence of asthma is associated with an increase in the risk of CKD.Methods We conducted a retrospective cohort study using data from 3015 patients with asthma aged 14 years and older who were registered and followed up in Asthma Control Study at the Department of Respiratory Medicine of three medical centers from 2005 to 2011.History,asthma control test (ACT),and asthma stage were used to assess the traits of asthma.CKD was defined as proteinuria and/or reduced estimated glomerular filtration rate (eGFR) (<60 ml·min-1·1.73 m-2) in two consecutive follow-up surveys.We used logistic regression models,adjusting for age,sex,and other confounding factor to determine associations between the traits of asthma and CKD.Kaplan-Meier curves were used to analyze patient outcomes.Results A total of 2354 subjects with complete data were recruited for this study with mean age (45.4±10.4) years.After 6 years of follow-up,9.6% (n=227) of the analytic cohort developed proteinuria and 3.1% (n=72) progressed to eGFR <60 ml·min-1·1.73 m-2.The patients with >20 years asthma history,not well-controlled or persistent asthma patients had higher incidence of proteinuria and reduced eGFR compared with patients with <20 years asthma history,at least well-controlled or remission asthma,respectively.The multivariable adjusted OR for proteinuria and reduced eGFR in participants with persistent asthma was 1.49; (95% confidence interval (CI) 1.17-1.91) and 2.07 (95% CI 1.34-4.42).Compared to patients with no asthma traits,there was a significant risk (OR,3.39; 95% CI 1.36-8.73) for those who met all three traits,including asthma history >20 years

    Asthma is a chronic disorder that can place considerable restrictions on the physical, emotional, and social aspects of the lives of patients. Inhaled glucocorticoids (GCs) are the most effective controller therapy. The purpose of this study was to evaluate the effect of inhaled GCs on quality of life in patients with moderate to severe asthma. Patients completed the asthma quality of life questionnaire (AQLQ) and pulmonary function test at baseline and after 4 wks treatment of GCs. We enrolled 60 patients who had reversibility in FEV1 after 200 microgram of albuterol of 15% or more and/or positive methacholine provocation test, and initial FEV1% predicted less than 80%. All patients received inhaled GCs (fluticasone propionate 1,000 microgram/day) for 4 wks. The score of AQLQ was significantly improved following inhaled GCs (overall 51.9+/-14.3 vs. 67.5+/-12.1, presponsiveness. Quality of life was improved after inhaled GCs regardless of asthma severity and GCs responsiveness in patients with moderate to severe asthma. PMID:16100448

    Aim: To evaluate the effect of inhaled formoterol-budesonide on airway remodeling in adult patients with moderate asthma.Methods: Thirty asthmatic patients and thirty control subjects were enrolled. Asthmatic subjects used inhaled Symbicort 4.5/160μg twice daily for one year. The effect of formoterol-budesonide on airway remodeling was assessed with comparing high-resolution computer tomography (HRCT) images of asthmatic patients and controls,as well as expression levels of cytokines and growth factors,inflammatory cell count in induced sputum,and airway hyper-responsiveness.Results: The differences in age and gender between the two groups were not significant. However,differences in FVC %pred,FEV1%pred,and PC20 between the two groups were significant. After treatment with formoterol-budesonide,the asthma patients' symptoms were relieved,and their lung function was improved. The WT and WA% of HRCT images in patients with asthma was increased,whereas treatment with formoterol-budesonide caused these values to decrease. The expression of MMP-9,TIMP-1,and TGF-β1 in induced sputum samples increased in patients with asthma and decreased dramatically after treatment with formoterol-budesonide.The WT and WA% are correlated with the expression levels of cytokines and growth factors,inflammatory cell count in induced sputum,and airway hyper-responsiveness,while these same values are correlated negatively with FEV1/FVC and FEV1%.Conclusion: Formoterol-budesonide might interfere in chronic inflammation and airway remodeling in asthmatic patients. HRCT can be used to effectively evaluate airway remodeling in asthmatic patients.

    Black and Hispanic children are hospitalized with complications of asthma at much higher rates than white children. The Boston Children's Hospital Community Asthma Initiative (CAI) provides asthma case management and home visits for children from low-income neighborhoods in Boston, Massachusetts, to address racial/ethnic health disparities in pediatric asthma outcomes. CAI objectives were to evaluate 1) case management data by parent/guardian report for health outcomes and 2) hospital administrative data for comparison between intervention and comparison groups. Data from parent/guardian reports indicate that CAI decreased the number of children with any (one or more) asthma-related hospitalizations (decrease of 79% at 12 months) and any asthma-related emergency department visits (decrease of 56% at 12 months) among children served, most of whom were non-Hispanic black or Hispanic. Hospital administrative data also indicate that the number of asthma-related hospitalizations per child significantly decreased among CAI participants compared with a comparison group. The CAI model has been replicated in other cities and states with adaptations to local cultural and systems variations. Health outcome and cost data have been used to contribute to a business case to educate legislators and insurers about outcomes and costs for this enhanced approach to care. Strong partnerships with public health, community, and housing agencies have allowed CAI to leverage its outcomes to expand systemic changes locally and statewide to reduce asthma morbidity.

    Eosinophils are one of the key inflammatory cells in asthma. Eosinophils can exert a wide variety of actions through expression and secretion of multiple molecules. Previously, we have demonstrated that eosinophils purified from peripheral blood from asthma patients express high levels of suppressor of cytokine signaling 3 (SOCS3). In this article, SOCS3 gene silencing in eosinophils from asthmatics has been carried out to achieve a better understanding of the suppressor function in eosinophils. SOCS3 siRNA treatment drastically reduced SOCS3 expression in eosinophils, leading to an inhibition of the regulatory transcription factors GATA-3 and FoxP3, also interleukin (IL)-10; in turn, an increased STAT3 phosphorilation was observed. Moreover, SOCS3 abrogation in eosinophils produced impaired migration, adhesion and degranulation. Therefore, SOCS3 might be regarded as an important regulator implicated in eosinophil mobilization from the bone marrow to the lungs during the asthmatic process. PMID:25764157

    2012-08-01

    Asthma is probably the most common serious medical disorder that may complicate pregnancy. A third of pregnant women with asthma will experience worsening of their symptoms, a third will see improvement of their symptoms and a third will see no change. The primary goal is to maintain optimal control of asthma for maternal health and well-being as well as fetal maturation. Vital patient education should cover the use of controller medication, avoidance of asthma triggers and early treatment of asthma exacerbations. Proper asthma management should ideally be started in the preconception period. Since smoking is probably the most modifiable risk factor of asthma, pregnant woman should avoid active and passive smoking. Acute asthma exacerbation during the first trimester is associated with an increased risk of congenital malformations. Poorly controlled asthma is associated with low birth weight, preeclampsia, and preterm birth. Medications used for asthma control in the non-pregnant population are generally the same in pregnancy with a few exceptions. Inhaled corticosteroids (ICS) are the preferred controller therapy. Budesonide is the preferred ICS. Long-acting B-agonists (LABA) are the preferred add-on therapy to medium to high dose ICS. Major triggers for asthma exacerbations during pregnancy are viral infections and ICS nonadherence. PMID:21858482

The conventional therapy is targeted to control the disease without targeting the loss of lung function or reversibility. In a prospective real-world observation of long-term use of add-on doxycycline as a matrix-metalloproteinase inhibitor, we documented significant improvement in lung function with possible reversal of remodeling.Background: Chronic asthma shows progressive decline in lung function with reduction or even loss of reversibility secondary to remodeling. A set of endopeptidase enzymes known as matrix metalloproteinases are intimately related to the pathogenesis of asthma and remodeling. The inhibition of matrix metalloproteinases is recognized as a prospective way of treating asthma and its corresponding structural remodeling.Methods: In a randomized, prospective, real-world study, we have observed the change in lung function (spirometry with an add-on of long-term doxycycline to standard asthma therapy as per the Global Initiative for Asthma guidelines in a small asthmatic population. The change in terms of forced expiratory volume (FEV1, forced vital capacity (FVC, percent of FEV1 (FEV1%, and forced expiratory flow (FEF25–75 were noted following variable duration of doxycycline therapy.Results: There has been a global improvement in all the parameters in all the six patients suggesting improvement in obstruction, and reduction in air trapping following a treatment of add-on doxycycline for a mean duration of 162.83 ± 83.07 days. Of the changes seen, the post bronchodilator FEV1, the FVC, and the FEF25–75 showed significant improvements with the P-value set at 0.004, 0.054, and 0.031, respectively.

    Objective To assess the value of fraction of exhaled nitric oxide (FeNO) measurements in the diagnosis of asthma in elderly patients. 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. PMID:27274212

    Results are reported of an investigation of the levels of cortisol, pancreatic and thyroid hormones in 38 patients with the infectious-allergic form of bronchial asthma. Unloading dietotherapy was accompanied by an improvement of the clinical course of the disease, reduction of necessity in broncholytic and hormonal agents. During the unloading dietotherapy period some variants of hormonal response to hunger were revealed. Patients with a severe course of the acidotic crisis revealed a reduction of the insulin level, changes in the cortisol dynamics, T4, a tendency to an increase of T3 in the blood. PMID:2330711

  12. Efficacy and safety of reslizumab in patients with moderate to severe eosinophilic asthma.

    2015-04-01

    Reslizumab, a neutralizing anti-IL-5 monoclonal antibody, is a promising adjunctive treatment for severe eosinophilic asthma. Monthly intravenous 3.0 mg/kg reslizumab had resulted in improvements in lung function and asthma control. It is well tolerated and common adverse events include headache, nasopharyngitis and upper respiratory tract infection. Rebound eosinophilia after cessation of reslizumab and attenuation of the treatment response with repeated dosing had been reported. Stringent selection of patients with a high eosinophil burden, who are poorly controlled despite moderate to high doses of inhaled corticosteroid, confers the most significant treatment response. Future trials should compare the dose, delivery platform, frequency of dosing and study combinations with other biologics, which will affect its maximal clinical efficacy. PMID:25578680

    Severe asthma is a complex and heterogeneous disease. The European Respiratory Society and American Thoracic Society guidelines define severe asthma for patients 6 years or older as "asthma which requires treatment with high-dose inhaled corticosteroids…plus a second controller or systemic corticosteroids to prevent it from becoming 'uncontrolled' or which remains 'uncontrolled' despite this therapy." This article reviews available traditional therapies, data behind their uses in severe asthma, and varying recommendations. As various asthma endotypes and phenotypes are better understood and characterized, targeted therapies should help improve disease outcomes, efficacy, and cost-effectiveness. PMID:27401628

Evaluating sleep quality to achieve good control of asthma is important since nocturnal asthmatic symptoms such as cough, wheezing, and chest tightness may disturb sleep. Actigraphy is an objective, ambulatory monitoring method for tracking a patient's sleep and wake activities and for assessing sleep quality, as reflected by total sleep time, sleep efficiency, duration of awakening after sleep onset (WASO, and sleep onset latency. Patients and methods: Fifty patients with asthma were enrolled in this study. Sleep quality was assessed employing wristwatch-type actigraphy (Actiwatch 2. The level of asthma control was assessed by the Asthma Control Questionnaire (ACQ, and asthma-related quality of life was assessed by the Asthma Quality of Life Questionnaire (AQLQ. The parameters for sleep quality were compared using ACQ scores, AQLQ scores, and pulmonary function test results. Results: The total sleep time was 387.2 minutes, WASO was 55.8 minutes, sleep efficiency was 87.01%, sleep onset latency was 8.17 minutes, and the average ACQ was 0.36. Neither sleep efficiency nor WASO correlated with respiratory functions, ACQ scores, or AQLQ scores. Conclusion: Sleep-related parameters assessed by actigraphy in well-controlled asthma do not correlate with pulmonary functions, the asthma control level, or daytime quality of life. Sleep

    Asthma affects millions of individuals worldwide. President Calvin Coolidge was one of these individuals. Coolidge suffered from asthma since childhood. It affected his outlook toward aggressive physical activity and was a strong factor in shaping his personality and, eventually, his politics. He was devoted to the status quo in American business enterprises and was known for his reserved personality and conservative political beliefs. One can speculate as to what role his passive personality, developed as a direct and conscious result of his desire for physical self-preservation in light of his asthma, played in leading the United States to the brink of the Great Depression. Dentists encounter individuals with asthma in their private practices daily. It is imperative that all dentists be aware of the symptoms of asthma, its many orofacial manifestations and possible modifications to dental treatment. PMID:22685914

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 < 0.001. The κ agreement between last clinical diagnosis of COPD and COPD based on 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.Keywords: asthma, COPD, diagnosis, primary care

    AIM: To investigate the possible relationships between alterations in circadian rhythm of melatonin, cortisol and bronchial asthma. METHODS: Salivary melatonin and cortisol were measured simultaneously by radioimmunoassay in 10 mild intermittent or persistent patients, 11 moderate-to-severe persistent asthma patients, and 15 control subjects. Twelve salivary samples were collected in a series during a 24-h period in each subject. RESULTS: The results showed overall lower levels of salivary melatonin in asthma patients compared with control subject (P<0.01). The amplitude, peak-level, and baseline of salivary melatonin were significantly lower in mild intermittent or persistent (P<0.01, P<0.05) and moderate-to-severe persistent asthma patients (P<0.01) compared with control group. The 24-h mean level of salivary cortisol was greatly lower and the acrophase was markedly delayed in patients with mild intermittent or persistent asthma (P<0.01) and moderate-to-severe persistent asthma (P<0.05, P<0.01) compared with control subject. CONCLUSION: Disordered circadian rhythms of salivary melatonin and cortisol were found in asthma patients, which may be involved in the pathogenesis of bronchial asthma.

    Full Text Available INTRODUCTION 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. OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSION Psychological counseling is advised for asthma patients in order to reduce their stress levels.

    Cough is the most common complaint for which patients seek medical attention. Cough variant asthma (CVA) is a form of asthma, which presents solely with cough. CVA is one of the most common causes of chronic cough. More importantly, 30 to 40% of adult patients with CVA, unless adequately treated, may progress to classic asthma. CVA shares a number of pathophysiological features with classic asthma such as atopy, airway hyper-responsiveness, eosinophilic airway inflammation and various features of airway remodeling. Inhaled corticosteroids remain the most important form of treatment of CVA as they improve cough and reduce the risk of progression to classic asthma most likely through their prevention of airway remodeling and chronic airflow obstruction.

    The measurement of rapid regional lung volume changes by electrical impedance tomography (EIT) could determine regional lung function in patients with obstructive lung diseases during pulmonary function testing (PFT). EIT examinations carried out before and after bronchodilator reversibility testing could detect the presence of spatial and temporal ventilation heterogeneities and analyse their changes in response to inhaled bronchodilator on the regional level. We examined seven patients suffering from chronic asthma (49  ±  19 years, mean age  ±  SD) using EIT at a scan rate of 33 images s(-1) during tidal breathing and PFT with forced full expiration. The patients were studied before and 5, 10 and 20 min after bronchodilator inhalation. Seven age- and sex-matched human subjects with no lung disease history served as a control study group. The spatial heterogeneity of lung function measures was quantified by the global inhomogeneity indices calculated from the pixel values of tidal volume, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), peak flow and forced expiratory flow between 25% and 75% of FVC as well as histograms of pixel FEV1/FVC values. Temporal heterogeneity was assessed using the pixel values of expiration times needed to exhale 75% and 90% of pixel FVC. Regional lung function was more homogeneous in the healthy subjects than in the patients with asthma. Spatial and temporal ventilation distribution improved in the patients with asthma after the bronchodilator administration as evidenced mainly by the histograms of pixel FEV1/FVC values and pixel expiration times. The examination of regional lung function using EIT enables the assessment of spatial and temporal heterogeneity of ventilation distribution during bronchodilator reversibility testing. EIT may become a new tool in PFT, allowing the estimation of the natural disease progression and therapy effects on the regional and not only global level. PMID

    Background 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+). Methods 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. Results 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, Pasthma FL+ group than in the COPD group (55.6% vs 25.0%, Pasthma FL+ group than in the ACOS group (76.28%±2.54% predicted vs 63.43%±3.22% predicted, Pasthma FL+ group than in the COPD group (112.05%±4.34% predicted vs 137.38%±3.43% predicted, Pasthma FL+ group (229±29 mL vs 153±21 mL, Pasthma FL+ group than in the COPD group at the whole-breath (4.29±0.30 cmH2O/L/s vs 3.41±0.14 cmH2O/L/s, Pasthma FL+, they may have distinct characteristics of the respiratory physiology and different responsiveness to bronchodilators.

    Asthma attacks are a major global source of morbidity and cost. The incidence and impact of asthma attacks have not improved despite widespread adoption of effective universal treatment guidelines. Consequently, there is increasing interest in managing asthma based on specific assessments of both current symptoms and future risk. In this review, we consider 'risk' in asthma, and how it might be assessed from the patient's history and objective measurements. We also discuss the potential for encouraging shared decision-making and improving medical consensus through explicit communication of risk and highlight the potential opportunities and challenges in risk assessment to improve asthma management through individualised treatment strategies.

    Full Text Available Context: Asthma is a complex disease with multiple genetic and environmental factors contributing to it. A component of this complexity is a highly variable response to pharmacological therapy. Pharmacogenomics is the study of the role of genetic determinants in the variable response to therapy. A number of examples of possible pharmacogenomic approaches that may prove of value in the management of asthma are discussed below. Evidence Acquisition: A search of PubMed, Google scholar, E-Medicine, BMJ and Mbase was done using the key words "pharmacogenomics of asthma", "pharmacogenomics of β-agonist, glucocorticoids, leukotriene modifiers, theophylline, muscarinic antagonists in asthma". Results: Presently, there are limited examples of gene polymorphism that can influence response to asthma therapy. Polymorphisms that alter response to asthma therapy include Arg16Gly, Gln27Glu, Thr164Ile for β-agonist receptor, polymorphism of glucocorticoid receptor gene, CRHR1 variants and polymorphism of LTC4S, ALOX5. Polymorphic variants of muscarinic receptors, PDE4 and CYP450 gene variants. Conclusion: It was concluded that genetic variation can improve the response to asthma therapy. However, no gene polymorphism has been associated with consistent results in different populations. Therefore, asthma pharmacogenomic studies in different populations with a large number of subjects are required to make possible tailoring the asthma therapy according to the genetic characteristic of individual patient.

    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.

    Patients' needs in asthma remain insufficiently understood and met. We therefore aimed to investigate the potential determinants of patients' needs in asthma treatment. Our study was based on survey data on 189 adults with asthma. Needs were measured using the 13-item Needs in Asthma Treatment questionnaire, which yields a total score and subscale-specific scores ('exacerbations', 'patient expertise', 'handling drugs' and 'drug effects'). We considered age, sex, education, years since diagnosis and anxiety/depression (measured by the Patient Health Questionnaire-4) as potential determinants. Associations were estimated by multivariable linear regression. Overall, we observed that younger age, poor mental health and a more recently established asthma diagnosis were independently associated with increased needs. Information on drug effects was an exception to this pattern as the need in that domain was solely determined by sex (being greater in men). In conclusion, our study provides novel evidence on patient characteristics that are associated with needs in asthma treatment. If confirmed by future studies, our observations may assist healthcare professionals to identify asthma patients with potentially elevated information, support and training needs and could contribute to the development of tailored interventions.

  15. Occupational asthma: a challenge in patient management and community care

    International Nuclear Information System (INIS)

    Occupational exposure to irritants accounts for 2% to 15% of all cases of asthma. Most of the offending agents evoke an IgE allergic reaction, but some seem to act through pharmacologic rather than immunologic pathways. Usually, symptoms are worse during working hours and improve in the evening and over the weekend, but in some cases onset is delayed. Symptoms may persist for weeks after exposure ceases. Skin tests or serologic tests for IgE antibody are helpful in diagnosis. Bronchial challenge with the suspected agent is valuable research procedure that occasionally is clinically useful in diagnosis. Management requires the cooperation of the medical and industrial communities. It consists of identifying asthmatic workers, removing them from exposure to the affecting environment, and treating their symptoms; preventing exposure of susceptible people through preemployment screening; and setting and adhering to reasonable occupational safety standards

    Background Recent studies have shown that T helper type-2 (Th2) cells can induce the apoptosis of CD4+CD25+ Treg cells or resist the immunosuppressive effect of Treg cells.We hypothesize that an imbalance of Th2/Treg is present in patients with allergic asthma.Methods Twenty-two patients with mild asthma,17 patients with moderate to severe asthma,and 20 healthy donors were enrolled.All patients were allergic to house dust mites.The proportion of peripheral blood CD4+CD25+ Treg cells and Th2 cells were determined by flow cytometry.The concentration of interleukin (IL)-10,transforming growth factor (TGF)-β and IL-4 in plasma was determined by enzyme linked immunosorbent assay.In these subjects,peripheral blood mononuclear cells from 17 mild asthmatic patients,13 moderate to severe asthmatic patients and 14 healthy donors were acquired and expression of forkhead box P3 (Foxp3) and GATA-3 mRNA was detected by reverse-transcriptase polymerase chain reaction.Results Compared with healthy donors and patients with mild asthma,the percent of CD4+CD25+ Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma.There were no significant differences in Foxp3 mRNA expression among three groups,but a downward trend seen among patients with asthma.However,the percent of Th2 cells,IL-4 levels and expression of GATA-3 mRNA was markedly higher in patients with mild and moderate to severe asthma than in the control group.The ratio of Th2/Treg and their cytokines was increased in allergic asthma,especially for moderate to severe asthma.The ratio of GATA-3/Foxp3 mRNA was also increased in allergic asthma.In patients with moderate to severe asthma,the percentage of peripheral blood Treg cells was negatively correlated to the percentage of Th2 cells and IL-4 levels.Conclusions The decline of CD4+CD25+ Treg cells in patients with moderate to severe asthma may play an important role in progress of the disease.Furthermore,the deficiency of CD4+CD25+ Treg

    Aspirin causes bronchoconstriction in aspirin-intolerant asthma (AIA) patients by triggering cysteinyl-leukotriene (cys-LT) production, probably by removing PGE2-dependent inhibition. To investigate why aspirin does not cause bronchoconstriction in all individuals, we immunostained enzymes of the leukotriene and prostanoid pathways in bronchial biopsies from AIA patients, aspirin-tolerant asthma (ATA) patients, and normal (N) subjects. Counts of cells expressing the terminal enzyme for cys-LT...

    Objectives The aim of this study was to explore barriers among patients, general practitioners (GPs) and practice nurses to implement internet-based self-management support as provided by PatientCoach for asthma in primary care. Setting Primary care within South Holland, the Netherlands. Participants Twenty-two patients (12 women, mean age 38 years), 21 GPs (6 women, mean age 52 years) and 13 practice nurses (all women, mean age 41 years). Design A qualitative study using focus groups and interviews. Outcomes Barriers as perceived by patients, GPs and practice nurses to implementation of PatientCoach. Methods 10 focus groups and 12 interviews were held to collect data: 4 patient focus groups, 4 GP focus groups, 2 practice nurse focus group, 2 patient interviews, 5 GP interviews and 5 practice nurse interviews. A prototype of PatientCoach that included modules for coaching, personalised information, asthma self-monitoring, medication treatment plan, feedback, e-consultations and a forum was demonstrated. A semistructured topic guide was used. Directed content analysis was used to analyse data. Reported barriers were classified according to a framework by Grol and Wensing. Results A variety of barriers emerged among all participant groups. Barriers identified among patients include a lack of a patient–professional partnership in using PatientCoach and a lack of perceived benefit in improving asthma symptoms. Barriers identified among GPs include a low sense of urgency towards asthma care and current work routines. Practice nurses identified a low level of structured asthma care and a lack of support by colleagues as barriers. Among all participant groups, insufficient ease of use of PatientCoach, lack of financial arrangements and patient characteristics such as a lack of asthma symptoms were reported as barriers. Conclusions We identified a variety of barriers to implementation of PatientCoach. An effective implementation strategy for internet-based self

    Full Text Available The aim of the present study was to determine whether aerobic exercise involving an active video game system improved asthma control, airway inflammation and exercise capacity in children with moderate to severe asthma.A randomized, controlled, single-blinded clinical trial was carried out. Thirty-six children with moderate to severe asthma were randomly allocated to either a video game group (VGG; N = 20 or a treadmill group (TG; n = 16. Both groups completed an eight-week supervised program with two weekly 40-minute sessions. Pre-training and post-training evaluations involved the Asthma Control Questionnaire, exhaled nitric oxide levels (FeNO, maximum exercise testing (Bruce protocol and lung function.No differences between the VGG and TG were found at the baseline. Improvements occurred in both groups with regard to asthma control and exercise capacity. Moreover, a significant reduction in FeNO was found in the VGG (p < 0.05. Although the mean energy expenditure at rest and during exercise training was similar for both groups, the maximum energy expenditure was higher in the VGG.The present findings strongly suggest that aerobic training promoted by an active video game had a positive impact on children with asthma in terms of clinical control, improvement in their exercise capacity and a reduction in pulmonary inflammation.Clinicaltrials.gov NCT01438294.

    Introduction The goal of asthma treatment is to obtain and maintain a good control of symptoms. Investigating factors associated with inadequately control asthma could help in strategies to improve asthma control. This study aimed to determine the prevalence and factors associated with inadequately controlled asthma in asthma patients under chest specialist care. Methods A cross-sectional study was conducted from November 2012 to May 2013. Physician-diagnosed asthma patients aged 12 years and above were included. A questionnaire was used to collect demographic data, comorbidities, and medical history of asthma. Asthma control was assessed using the Asthma Control Test (ACT), with a score less than 20 for inadequately controlled asthma and a score greater or equal to 20 for controlled asthma. A multivariate analysis was used to identify factors associated with inadequately controlled asthma. Results Overall, 243 patients were included in this study. Asthma was controlled in 141 patients (58%) and inadequately controlled in 102 (42%). The mean duration of asthma was 8 years with an interquartile range of 4 and 18 years. Forty-three participants (17.7%) were not under any controller medication while the mean ACT score was 19.3 ± 4.6. Independent associations were found between inadequately controlled asthma and female gender (OR 1.91; 95% CI 1.06-3.47) and obesity (OR 1.81; 1.01-3.27). Conclusion Asthma remains poorly controlled in a large proportion of asthma patients under specialist care in Cameroon. Educational programs for asthma patients targeting women and based on weight loss for obese patients may help in improving the control of asthma. PMID:27217894

    Full Text Available Now that it is generally accepted that asthma is a heterogeneous condition, phenotyping of asthma patients has become a mandatory part of the diagnostic workup of all patients who do not respond satisfactorily to standard therapy with inhaled corticosteroids. Late-onset eosinophilic asthma is currently one of the most well-defined asthma phenotypes and seems to have a different underlying pathobiology to classical childhood-onset, allergic asthma. Patients with this phenotype can be identified in the clinic by typical symptoms (few allergies and dyspnoea on exertion, typical lung function abnormalities (“fixed” airflow obstruction, reduced forced vital capacity and increased residual volume, typical comorbidities (nasal polyposis and a good response to systemic corticosteroids. The definitive diagnosis is based on evidence of eosinophilia in bronchial biopsies or induced sputum, which can be estimated with reasonable accuracy by eosinophilia in peripheral blood. Until recently, patients with eosinophilic asthma had a very poor quality of life and many suffered from frequent severe exacerbations or were dependent on oral corticosteroids. Now, for the first time, novel biologicals targeting the eosinophil have become available that have been shown to be able to provide full control of this type of refractory asthma, and to become a safe and efficacious substitute for oral corticosteroids.

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

    Full Text Available Abstract Background Multiple studies have linked fungal exposure to asthma, but the link to severe asthma is controversial. We studied the relationship between asthma severity and immediate type hypersensitivity to mold (fungal and non-mold allergens in 181 asthmatic subjects. Methods We recruited asthma patients aged 16 to 60 years at a University hospital and a nearby General Practice. Patients were categorized according to the lifetime number of hospital admissions for asthma (82 never admitted, 53 one admission, 46 multiple admissions. All subjects had allergy skin prick tests performed for 5 mold allergens (Aspergillus, Alternaria, Cladosporium, Penicillium and Candida and 4 other common inhalant allergens (D. pteronyssinus, Grass Pollen, Cat and Dog. Results Skin reactivity to all allergens was commonest in the group with multiple admissions. This trend was strongest for mold allergens and dog allergen and weakest for D. pteronyssinus. 76% of patients with multiple admissions had at least one positive mold skin test compared with 16%-19% of other asthma patients; (Chi squared p Conclusion These findings support previous suggestions that mold sensitization may be associated with severe asthma attacks requiring hospital admission.

  11. Associated factors to repeated consultations to the urgencies service for asthma in pediatric patient: Implications for an educational program

    International Nuclear Information System (INIS)

    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.

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. In summary, budesonide/formoterol pMDI is effective and well tolerated and has additional therapeutic benefits that may be important from the patient’s perspective.Keywords: budesonide, formoterol, patient-reported outcomes, efficacy, tolerability, onset of effect

    Full Text Available Introduction. Asthma is a chronic disease, from which more and more people in the world suffer. It is connected with many bothersome symptoms and limitations, which result in decreased quality of life for the patient. Environmental and individual aspects do not necessarily affect individuals in the same way, so it is necessary to determine which factors have predominantly impacted on an individual, in order to minimize their impact and to take better control over treatment of asthma. The aim of this research was to compare the quality of life among patients with bronchial asthma living in Krakow in the areas where they get exposed to varying concentrations of particulate matter (PM10. Material and methods. The study included 98 adults diagnosed with bronchial asthma. The research was conducted using the AQLQ poll. PM10 concentration was measured in several Malopolska Air Pollution Monitoring Stations located throughout the city. Results. Analyzing the quality of life in the view of symptoms, activity limitations and emotional well being, there was a substantial statistical difference observed in people occupying the areas with different PM10 concentrations. No significant statistical difference was observed in the frequency of asthma symptoms caused by the environmental stimuli between the 2 discussed groups. One group of patients who came to the allergy clinic for control of asthma symptoms and the second group who live in the vicinity of the monitoring stations measuring PM10 concentrations. Conclusions. For many of the cases, the quality of life was not worse for patients with asthma living in an area with slightly elevated concentrations of PM10, and sometimes paradoxically the quality of life was improved. These results show that PM10 concentrations do not correlate with quality of life of asthma patients.

    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

    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.

    Disease severity in asthma can be classified as mild, moderate or severe based upon the frequency of symptoms or the severity of airflow obstruction. This review will focus on the treatment of youths greater than 12 years of age and adults with moderate persistent asthma. Moderate asthmatics may have daily symptoms that cause some limitation with normal daily activities and require use of a rescue inhaled short-acting beta2-agonist inhaler or experience nocturnal awakenings secondary to asthm...

    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.

    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.

    Full Text Available Robert Barrons,1 James Wheeler,2 J Andrew Woods1 1Wingate University School of Pharmacy, Wingate, NC, USA; 2University of Tennessee Health Science Center, Nashville, TN, USA Abstract: An anticipated surge in the elderly population will be accompanied by a rise in aging patients with asthma or COPD. Clinician selection of inhalers needs to address the unique challenges to elderly patients. These challenges to the use of inhalers include diminished physical and cognitive abilities, as well as cost reimbursement issues associated with polypharmacy and the Medicare gap. Clinicians should consider patient preferences for an inhaler device that provides ease of administration, and addresses conveniences such as portability, visual, and auditory indicators of dosing completion. The addition of spacer devices resolves hand-breath coordination difficulty with pressurized metered dose inhalers, but reduces overall inhaler convenience. Soft mist inhalers (Respimat® improve ease of administration, but use may be limited by cost and formulary availability. Multiple dose dry powder inhalers provide convenience and simplified use by requiring only one to two steps prior to administration, but concerns of peak inspiratory flow requirements remain among patients with advanced age and severity of COPD. If unaddressed, these challenges to inhaler selection contribute to inappropriate use of inhalers in 41% to 69% of patients, accompanied by at least 51% non-adherence to treatment. Clinicians must first avail themselves of reputable educational resources regarding new inhaler developments and administration, for competent patient instruction. Patient education should include a checklist of inhaler technique, with physical demonstration of each device by the patient and provider. Device demonstration significantly improves inhaler technique and identifies the need for nebulization therapy. Clinician and patient knowledge of available inhalers and their

    Respiratory infections are well-known triggers of chronic respiratory diseases. Recently, culture-independent tools have indicated that lower airway microbiota may contribute to pathophysiologic processes associated with asthma and chronic obstructive pulmonary disease (COPD). However, the relationship between upper airway microbiota and chronic respiratory diseases remains unclear. This study was undertaken to define differences of microbiota in the oropharynx of asthma and COPD patients relative to those in healthy individuals. To account for the qualitative and quantitative diversity of the 16S rRNA gene in the oropharynx, the microbiomes of 18 asthma patients, 17 COPD patients, and 12 normal individuals were assessed using a high-throughput next-generation sequencing analysis. In the 259,572 total sequence reads, α and β diversity measurements and a generalized linear model revealed that the oropharynx microbiota are diverse, but no significant differences were observed between asthma and COPD patients. Pseudomonas spp. of Proteobacteria and Lactobacillus spp. of Firmicutes were highly abundant in asthma and COPD. By contrast, Streptococcus, Veillonella, Prevotella, and Neisseria of Bacteroidetes dominated in the healthy oropharynx. These findings are consistent with previous studies conducted in the lower airways and suggest that oropharyngeal airway microbiota are important for understanding the relationships between the various parts of the respiratory tract with regard to bacterial colonization and comprehensive assessment of asthma and COPD.

    Full Text Available BACKGROUND Chronic pulmonary diseases are a global health problem and the number of patients being treated in primary care settings is increasing. The prevalence of a life-time diagnosis of asthma has increased in all age groups. There has been a dramatic shift in the conceptualization and treatment of asthma and COPD in the last 50 years. Psychiatric disorders, especially anxiety disorders, are very common in patients with asthma and COPD. Anxiety is also common in COPD and is related to some of the same factors described for asthma including the psychological response to the experience of breathlessness as well as side effects of beta-agonists. Since there is paucity of relevant data from Kashmir, this study was designed to find the co morbidity in patients of COPD and Asthma in a tertiary care teaching hospital in Srinagar, Kashmir. METHODS Sixty successive patients presents with history of thirty each of asthma and COPD who fulfilled inclusion and exclusion criteria were taken up for the study and administered the Hamilton depression rating scale (HAM-D and Hamilton Anxiety rating scale (HAM-A scales for evaluation of depressive disorder and anxiety disorder. Each patient was informed about the purpose of interview; his/her consent was obtained and strict confidentiality was ensured. General description, demographic data and psychiatric history were recorded using semi structured Proforma and HAM-A and HAM-D. RESULTS Out of sixty cases of COPD and Bronchial Asthma, 50% of the patients were in the age group of 66-80 followed by 35% in age group of 81-85 years. This could suggest that COPD and Bronchial Asthma is a problem of old age. There were predominantly more males (65% than females (35% in our study. Representations of gender, religion, family type and marital status have been found to be in accordance with socio-demographic profile of our country. Out of sixty cases of COPD and Bronchial Asthma, 35% of the patients were educated up to

    2016-01-01

    Asthma is one of the most common chronic pediatric diseases. Patients with asthma often present to the emergency department for treatment for acute exacerbations. These patients may not have a primary care physician or primary care home, and thus are seeking care in the emergency department. Asthma care in the emergency department is multifaceted to treat asthma patients appropriately and provide quality care. National and international guidelines exist to help drive clinical care. Electronic and paper-based tools exist for both physicians and patients to help improve emergency, home, and preventive care. Treatment of patients with asthma should include the acute exacerbation, long-term management of controller medications, and controlling triggers in the home environment. We will address the current state of asthma research in emergency medicine in the US, and discuss some of the resources being used to help provide a medical home and improve care for patients who suffer from acute asthma exacerbations.

    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...

    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.

  17. Multislice helical CT analysis of small-sized airway wall thickness in smokers and patients with bronchial asthma

    International Nuclear Information System (INIS)

    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 β2 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 %V50 and %V25 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)

    Kaslovsky, Robert; Gottsegen, David

    2015-10-01

    Wheezing in children often is the result of asthma, but vocal cord dysfunction (VCD) may cause stridor or sounds that sometimes are misattributed to the wheezing of asthma. The frequent comorbidity of asthma and VCD also adds to the difficulty in making a clear diagnosis. The challenges of evaluating and treating wheezing are complicated further in children with developmental disorders, such as autism, because of the difficulties of obtaining an adequate history and assessing the clinical response to treatment. This article presents a patient with multiple psychiatric problems, including autism, with severe recurrent wheezing as a result of vocal cord dysfunction and asthma. Hypnosis has previously proven efficacious for treating vocal cord dysfunction, and in this case, hypnotic techniques were major factors in successful symptom control. PMID:26264542

    Full Text Available Balaji Laxmanan, D Kyle Hogarth Section of Pulmonary and Critical Care Medicine, University of Chicago Medicine, Chicago, IL, USA Abstract: Bronchial thermoplasty (BT is a novel therapy for patients with severe asthma. Using radio frequency thermal energy, it aims to reduce the airway smooth muscle mass. Several clinical trials have demonstrated improvements in asthma-related quality of life and a reduction in the number of exacerbations following treatment with BT. In addition, recent data has demonstrated the long-term safety of the procedure as well as sustained improvements in rates of asthma exacerbations, reduction in health care utilization, and improved quality of life. Further study is needed to elucidate the underlying mechanisms that result in these improvements. In addition, improved characterization of the asthma subphenotypes likely to exhibit the largest clinical benefit is a critical step in determining the precise role of BT in the management of severe asthma.

METHODS AND FINDINGS: Asthma and rhinitis HRQoL, illness perception, mood profiles, rhinitis symptoms and asthma control were assessed by means of validated tools in patients classified according to GINA and ARIA guidelines. Optimal HRQoL, identified by a Rhinasthma Global Summary (GS score ≤20 (score ranging from 0 to 100, where 100 represents the worst possible HRQoL, was reached by 78/209 (37.32%. With the exception of age, no associations were found between clinical and demographic characteristics and optimal HRQoL achievement. Patients reaching an optimal HRQoL differed in disease perception and mood compared to those not reaching an optimal HRQoL. Asthma control was significantly associated with optimal HRQoL (χ(2 = 49.599; p<0.001 and well-controlled and totally controlled patients significantly differed in achieving optimal HRQoL (χ(2 = 7.617; p<0.006. CONCLUSION: Approximately one third of the patients in our survey were found to have an optimal HRQoL. While unsatisfactory disease control was the primary reason why the remainder failed to attain optimal HRQoL, it is clear that illness perception and mood also played parts. Therefore, therapeutic plans should be directed not only toward achieving the best possible clinical control of asthma and comorbid rhinitis, but also to incorporating individualized elements according to patient-related characteristics.

    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.

    We report here on the redistributed regional ventilation abnormalities after the administration of a bronchodilator and as seen on xenon-inhaled dual-energy CT in a patient with asthma. The improved ventilation seen in the right lower lobe and the decreased ventilation seen in the right middle lobe after the administration of a bronchodilator on xenon-inhaled dual-energy CT could explain a positive bronchodilator response on a pulmonary function test. These changes may reflect the heterogeneity of the airway responsiveness to a bronchodilator in patients with asthma.

    Yao Liu

    Full Text Available BACKGROUND: Interleukin (IL-5 is believed to be a key cytokine in eosinophil inflammatory infiltration in asthma. Previous clinical trials have evaluated the efficacy and safety of mepolizumab, a monoclonal antibody against IL-5, in patients with asthma. However, most of these studies were small, the conclusions were inconsistent, and the precise effects are therefore debatable. METHODS: A meta-analysis of randomized placebo-controlled trials was conducted to evaluate the effect of intravenous infusion of mepolizumab on clinical outcomes in patients with asthma. Trials were searched in PubMed, Embase, Web of Science, Cochrane CENTRAL, Scopus, reviews, and reference lists of relevant articles. The outcome variables analyzed included eosinophil counts in blood and sputum, airways outcome measures, exacerbations, asthma control, and quality of life scores. RESULTS: Seven studies met final inclusion criteria (total n = 1131. From the pooled analyses, mepolizumab significantly reduced eosinophils in blood (MD -0.29×10(9/L, 95% CI -0.44 to -0.14×10(9/L, P = 0.0001 and sputum (MD -6.05%, 95% CI -9.34 to -2.77%, P = 0.0003. Mepolizumab was also associated with significantly decreased exacerbation risk than placebo (OR 0.30, 95%CI 0.13 to 0.67, P = 0.004, and with a significant improvement in the scores on the Asthma Quality of Life Questionnaire (AQLQ (MD 0.26, 95% CI 0.03 to 0.49, P = 0.03 in patients with eosinophilic asthma. There were no statistical differences between the groups with respect to FEV1, PEF, or histamine PC20 (all P>0.05, and a non-significant trend for improvement in scores on the Juniper Asthma Control Questionnaire (JACQ (MD -0.21, 95% CI -0.43 to 0.01, P = 0.06 in the mepolizumab group was observed. CONCLUSIONS: Mepolizumab reduces the risk of exacerbations and improves quality of life in patients with eosinophilic asthma, but no significant improvement in lung function outcomes was observed.

    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.

    Full Text Available OBJECTIVES:Asthma is a chronic inflammatory lung disease characterized by bronchial hyperresponsiveness and airflow obstruction. Genetic and oxidative stress factors, in addition to pulmonary and systemic inflammatory processes, play a pivotal role in the pathogenesis of asthma. The products of the multidrug resistance-1 gene protect lung tissue from oxidative stress. Here, we aimed to evaluate the association between the multidrug resistance-1 gene C>T polymorphism and asthma with regard to oxidative stress-related parameters of asthmatic patients.METHODS:Forty-five patients with asthma and 27 healthy age-matched controls were included in this study. Blood samples were collected in tubes with ethylenediaminetetraacetic acid. DNA was extracted from the blood samples. The multidrug resistance-1 gene polymorphism was detected by polymerase chain reaction and a subsequent enzyme digestion technique. The serum levels of total oxidant status and total antioxidant status were determined by the colorimetric measurement method.RESULTS:The heterozygous polymorphic genotype was the most frequent in both groups. A significant difference in the multidrug resistance-1 genotype frequencies between groups indicated an association of asthma with the TT genotype. A significant difference between groups was found for wild type homozygous participants and carriers of polymorphic allele participants. The frequency of the T allele was significantly higher in asthmatic patients. The increase in the oxidative stress index parameter was significant in the asthma group compared with the control group.CONCLUSIONS:The multidrug resistance-1 gene C/T polymorphism may be an underlying genetic risk factor for the development of asthma via oxidant-antioxidant imbalance, leading to increased oxidative stress.

    Except for FVC which had a significant correlation with BMI, other studied indices yielded no significant results, which calls for more extensive studies with larger populations. Considering the fact that mild asthma is less common in obese patients, better weight control in asthmatic patients can promote their quality of life and make asthma management more effective.

    Inhaled corticosteroids (ICS) are the most effective controller medications for asthma, and variability in ICS response is associated with genetic variation. Despite ICS treatment, some patients with poor asthma control experience severe asthma exacerbations, defined as a hospitalization or emergency room visit. We hypothesized that some individuals may be at increased risk of asthma exacerbations, despite ICS use, due to genetic factors. A GWAS of 237,726 common, independent markers was conducted in 806 Caucasian asthmatic patients from two population-based biobanks: BioVU, at Vanderbilt University Medical Center (VUMC) in Tennessee (369 patients), and Personalized Medicine Research Project (PMRP) at the Marshfield Clinic in Wisconsin (437 patients). Using a case-control study design, the association of each SNP locus with the outcome of asthma exacerbations (defined as asthma-related emergency department visits or hospitalizations concurrent with oral corticosteroid use), was evaluated for each population by logistic regression analysis, adjusting for age, gender and the first four principal components. A meta-analysis of the results was conducted. Validation of expression of selected candidate genes was determined by evaluating an independent microarray expression data set. Our study identified six novel SNPs associated with differential risk of asthma exacerbations (P < 10(-05)). The top GWAS result, rs2395672 in CMTR1, was associated with an increased risk of exacerbations in both populations (OR = 1.07, 95% CI 1.03-1.11; joint P = 2.3 × 10(-06)). Two SNPs (rs2395672 and rs279728) were associated with increased risk of exacerbations, while the remaining four SNPs (rs4271056, rs6467778, rs2691529, and rs9303988) were associated with decreased risk. Three SNPs (rs2395672, rs6467778, and rs2691529) were present in three genes: CMTR1, TRIM24 and MAGI2. The CMTR1 mRNA transcript was significantly differentially expressed in nasal lavage samples

    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.

    Sahadevan, A; Cusack, R; Lane, S J

    2015-01-01

    Seasonal allergic rhinitis (AR) occurs predominantly as a result of grass pollen allergy. Grass pollen sublingual immunotherapy (SLIT) has been proven effective in treating AR1. SLIT is currently licensed for use in AR with concomitant stable mild asthma. There is evidence that SLIT improves asthma control when primarily used to treat AR2. The aim was to assess the safety of SLIT in patients with severe seasonal allergic rhinitis who have co-existing stable mild asthma. The secondary aim was to determine whether asthma control improved post SLIT. There was no deterioration in asthma control after 6-36 months of SLIT. 27/30 (90%) patients' asthma control remained stable or indeed improved (p < 0.021). Of this 15 (50%) patients' asthma improved. There was no statistically significant change in their asthma pharmacotherapy after SLIT (p = 0.059). In conclusion, grass pollen SLIT is safe and can potentially treat dual allergic rhinitis- mild asthmatic patients. PMID:26817287

    In 2015, progress in understanding asthma ranged from insights to asthma inception, exacerbations, and severity to advancements that will improve disease management throughout the lifespan. 2015's insights to asthma inception included how the intestinal microbiome affects asthma expression with the identification of specific gastrointestinal bacterial taxa in early infancy associated with less asthma risk, possibly by promoting regulatory immune development at a critical early age. The relevance of epigenetic mechanisms in regulating asthma-related gene expression was strengthened. Predicting and preventing exacerbations throughout life might help to reduce progressive lung function decrease and disease severity in adulthood. Although allergy has long been linked to asthma exacerbations, a mechanism through which IgE impairs rhinovirus immunity and underlies asthma exacerbations was demonstrated and improved by anti-IgE therapy (omalizumab). Other key molecular pathways underlying asthma exacerbations, such as cadherin-related family member 3 (CDHR3) and orosomucoid like 3 (ORMDL3), were elucidated. New anti-IL-5 therapeutics, mepolizumab and reslizumab, were US Food and Drug Administration approved for the treatment of patients with severe eosinophilic asthma. In a clinical trial the novel therapeutic inhaled GATA3 mRNA-specific DNAzyme attenuated early- and late-phase allergic responses to inhaled allergen. These current findings are significant steps toward addressing unmet needs in asthma prevention, severity modification, disparities, and lifespan outcomes. PMID:27497278

    Full Text Available Abstract Background Myofibroblasts, proposed as being derived from circulating fibrocytes, are considered to be important cells in thickening of the basement membrane in patients with asthma. We have studied the correlation of tissue fibrocyte levels to basement membrane thickness and the presence of fibrocytes in bronchoalveolar lavage fluid (BALF in steroid-naive patients with mild asthma and controls. Methods Patients with mild asthma (n = 9 were recruited and divided into two categories based on whether or not fibroblast-like cells could be established from BALF. Non-asthmatic healthy subjects (n = 5 were used as controls. Colocalization of the fibrocyte markers CD34, CD45RO, procollagen I, and α-smooth muscle actin (α-SMA were identified in bronchial biopsies from patients and controls by confocal microscopy. Kruskall-Wallis method was used to calculate statistical significance and Spearman coefficient of rank correlation was used to assess the degree of association. Results In patients with BALF fibroblasts, a 14-fold increase of tissue cells expressing CD34/CD45RO/α-SMA and a 16-fold increase of tissue cells expressing CD34/procollagen I was observed when compared to controls (p Conclusion These findings indicate a correlation between recruited fibrocytes in tissue and thickness of basement membrane. Fibroblast progenitor cells may therefore be important in airway remodeling in steroid-naive patients with mild asthma.

    Full Text Available Background: Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained. Objectives: This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma and pulmonary function in patients with hypogammaglobulinemia. Patients and Methods: We used the international study of asthma and allergies in childhood (ISAAC questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years. Results: Spirometry results were normal in 21 (51%, and showed obstructive in 15 (37% and restrictive pattern in 5 (12% of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20% patients and other atopies (rhinitis and dermatitis identified in 10 (22%, and four (9%, respectively. Conclusions: Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.

    Patient decision support (PDS) tools or decision aids have been developed as adjuncts to the clinical encounter. Their aim is to support evidence-based patient choice. Clinical trials of PDS tools have used an array of outcome measures to determine efficacy, including knowledge, satisfaction, health status and consistency between patient choice and values. This paper proposes that the correlation between 'subjective expected utility' (SEU) and decision may be the best primary endpoint for trials. SEU is a measure usually used in behavioural decision theory. The paper first describes how decision support tools may use decision analysis to structure the presentation of evidence and guide patient decision-making. Uses of expected utility (EU) are suggested for evaluating PDS tools when improving population health status is the objective. SEU is the theoretically better measure when internal consistency of patient choices is the objective. PMID:11083037

    Full Text Available Asthma is considered as a chronic inflammatory airway disease and defined as increased tracheobronchial responsiveness to variety of stimuli. Edema and inflammatory cell infiltration in airway is observed in the asthmatic patients. One of the essential changes in inflammation is adhesion of leukocyte to endothelium and transmigration of leukocytes to the sites of inflammation. Unfortunately, little is known about the role of platelet endothelial cell adhesion molecule-1 (PECAM-1 polymorphism in asthma inflammatory process. The purpose of this study was to determine whether PECAM-1 polymorphisms affect the risk of asthma or not.Forty-five asthmatic patients (including 27 men and 18 women and 45 healthy volunteers (11 men and 34 women were studied. To determine the severity of the asthmas situation, a questionnaire was prepared asking the following information: age, sex, clinical signs and symptoms and past medical history. All subjects were genotyped for PECAM-1 polymorphism by using amplification refractory mutation system -polymerase chain reaction (ARMS-PCR. The genotype distribution of PECAM-1 80 Val/Met polymorphism in all asthmatic patients were Val/Val while non asthmatic controls were 95.6% Val/Val and 4.4% Val/Met. However, these differences were not statistically significant (p<0.05. The allele and genotype frequencies of PECAM-1 125 Val/Leu polymorphism were significantly different between asthmatic patients and controls. On the other hand, the presence of 125 Leu allele was associated with an increasing risk of asthma with an odds ratio of 2.8 (95% CI; 1.5-5.3, p=0.002. Our findings suggest that the PECAM-1 125 Val/leu polymorphism might be a genetic factor that may be associated with asthma.

    Full Text Available The study included 39 patients with bronchial asthma. All patients at baseline were stratified into two groups with the genotype AA and AG of polymorphism Asp299Gly TLR-4. The study consisted of 2 periods: a 2-weeks’ run-in period when all patients received low-dose (125 mg of fluticasone propionate once a day; 24-weeks’ treatment period when patients received fluticasone propionate once a day or 1 tablet (10 mg of montelukast per day depending on randomization subgroups. The study results showed that taking of fluticasone propionate by patients with AA genotype TLR-4 for 24 weeks is more effective than montelukast taking; this is evi¬denced by a significant increase of FEV1 and improvement of indices of asthma control level (ACL and quality of life of patients (AQLQ (S. In patients with AG genotype clinical efficacy of montelukast is superior to fluticasone propionate.

    Full Text Available Asthma is a chronic inflammatory disease of the airways that may lead to limitations in regular activities, to hospitalizations and a decrease in quality of life. Adherence to drug treatment is crucial for control of the disease. The use of medicinal herbs can reduce adherence to prescriptions, as the medication may be replaced by infusions or herbal products. The objective of this study was to evaluate the frequency of use of traditional herbal medicine among severe asthmatics in Salvador. Information on use of homemade remedies was obtained through application of a questionnaire during patient visits to a referral center. We also collected data on economic and social aspects as well as disease control. One hundred and forty-four (91,1% out of one hundred and fifty-eight patients evaluated used herbal medicines, but only 26.5% attributed improvement of asthma symptoms to this alternative treatment and only 8 had substituted a prescribed medication by herbal medicines. There was a trend towards lower adherence to prescription drug treatment in this group of patients. Despite the high frequency of use of medicinal herbs in our sample, there was no improvement in the asthma treatment in this population compared to non-users. Adherence to conventional drug treatment was satisfactory and there was neither reduction in asthma control nor increase in hospitalizations among the users of medicinal plants.A asma é uma enfermidade inflamatória crônica das vias aéreas que pode resultar em limitações nas atividades diárias, internações e prejuízo da qualidade de vida.

    Full Text Available Purpose: Methods used to deliver and test a pharmacy-based asthma care telephonic service for an underserved, rural patient population are described. Summary: In a randomized controlled trial (RCT, the Patient And phaRmacist Telephonic Encounters (PARTE project is assessing the feasibility, acceptability, and preliminary impact of providing pharmacy-based asthma care service telephonically. The target audience is a low income patient population across a large geographic area served by a federally qualified community health center. Ninety-eight participants have been randomized to either standard care or the intervention group who received consultation and direct feedback from pharmacists via telephone regarding their asthma self-management and medication use. Pharmacists used a counseling framework that incorporates the Indian Health Services 3 Prime Questions and the RIM Technique (Recognition, Identification, and Management for managing medication use problems. Pharmacists encouraged patients to be active partners in the decision-making process to identify and address the underlying cause of medication use problems. Uniquely, this trial collected process and summative data using qualitative and quantitative approaches. Pharmacists’ training, the fidelity and quality of pharmacists’ service delivery, and short term patient outcomes are being evaluated. This evaluation will improve our ability to address research challenges and intervention barriers, refine staff training, explore patient perspectives, and evaluate measures’ power to provide preliminary patient outcome findings. Conclusion: A mixed method evaluation of a structured pharmacist intervention has the potential to offer insights regarding staff training, service fidelity and short term outcomes using quantitative and qualitative data in an RCT. Results will provide evidence regarding the feasibility and quality of carrying out the study and service delivery from the multiple

  18. High-resolution computed tomography findings in elderly patients with asthma

    International Nuclear Information System (INIS)

    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

    Full Text Available ABSTRACT OBJECTIVE: To identify, characterize, and quantify associations of various factors with quality of life (QoL in patients with asthma, according to the pharmacotherapy employed. METHODS: This was a cross-sectional study involving 49 patients (≥ 18 years of age with severe uncontrolled or refractory asthma treated at a specialized outpatient clinic of the Brazilian Unified Health Care System, regularly using high doses of inhaled corticosteroids (ICs or other medications, and presenting comorbidities. At a single time point, QoL was assessed with the Asthma Quality of Life Questionnaire (AQLQ. The overall AQLQ score and those of its domains were correlated with demographic variables (gender and age; Asthma Control Questionnaire score; pharmacotherapy (initial IC dose, inhaler devices, and polytherapy; and comorbidities. RESULTS: Better AQLQ scores were associated with asthma control-overall (OR = 0.38; 95% CI: 0.004-0.341; p < 0.001, "symptoms" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001, and "emotional function" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001-and with IC dose ≤ 800 µg-"activity limitation" domain (OR = 0.249; 95% CI: 0.070-0.885; p = 0.029. Worse AQLQ scores were associated with polytherapy-"activity limitation" domain (OR = 3.651; 95% CI: 1.061-12.561; p = 0.036-and number of comorbidities ≤ 5-"environmental stimuli" domain (OR = 5.042; 95% CI: 1.316-19.317; p = 0.015. CONCLUSIONS: Our results, the importance of this issue, and the lack of studies taking pharmacotherapy into consideration warrant longitudinal studies to establish a causal relationship between the identified factors and QoL in asthma patients.

  1. Absence of pulmonary aspiration of sinus contents in patients with asthma and sinusitis

    International Nuclear Information System (INIS)

    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

    Full Text Available BACKGROUND AND OBJECTIVES: Asthma and depression are common health problems in primary care. Evidence of a relationship between asthma and depression is conflicting. OBJECTIVES: to determine 1. The incidence rate and incidence rate ratio of depression in primary care patients with asthma compared to those without asthma, and 2. The standardized mortality ratio of depressed compared to non-depressed patients with asthma. METHODS: A historical cohort and nested case control study using data derived from the United Kingdom General Practice Research Database. PARTICIPANTS: 11,275 incident cases of asthma recorded between 1/1/95 and 31/12/96 age, sex and practice matched with non-cases from the database (ratio 1:1 and followed up through the database for 10 years. 1,660 cases were matched by date of asthma diagnosis with 1,660 controls. MAIN OUTCOME MEASURES: number of cases diagnosed with depression, the number of deaths over the study period. RESULTS: The rate of depression in patients with asthma was 22.4/1,000 person years and without asthma 13.8 /1,000 person years. The incident rate ratio (adjusted for age, sex, practice, diabetes, cardiovascular disease, cerebrovascular disease, smoking was 1.59 (95% CI 1.48-1.71. The increased rate of depression was not associated with asthma severity or oral corticosteroid use. It was associated with the number of consultations (odds ratio per visit 1.09; 95% CI 1.07-1.11. The age and sex adjusted standardized mortality ratio for depressed patients with asthma was 1.87 (95% CI: 1.54-2.27. CONCLUSIONS: Asthma is associated with depression. This was not related to asthma severity or oral corticosteroid use but was related to service use. This suggests that a diagnosis of depression is related to health seeking behavior in patients with asthma. There is an increased mortality rate in depressed patients with asthma. The cause of this needs further exploration. Consideration should be given to case-finding for

    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.

  9. Role of Leukotrienes and Leukotriene Modifiers in Asthma

    2010-06-01

    Full Text Available Leukotrienes (LTs, including cysteinyl LTs (CysLTs and LTB4, are potent lipid mediators that are pivotal in the pathophysiology of asthma phenotypes. At least two receptor subtypes for CysLTs – CysLT1 and CysLT2 – have been identified. Most of the pathophysiological effects of CysLTs in asthma, including increased airway smooth muscle activity, microvascular permeability and airway mucus secretion, are mediated by the activation of the CysLT1 receptor. LTB4 may have a role in the development of airway hyperresponsiveness, severe asthma and asthma exacerbations. Although generally less effective than inhaled glucocorticoids, CysLT1 receptor antagonists can be given orally as monotherapy in patients with persistent mild asthma. In patients with more severe asthma, CysLT1 receptor antagonists can be combined with inhaled glucocorticoids. This therapeutic strategy improves asthma control and enables the dose of inhaled glucocorticoids to be reduced, while maintaining similar efficacy. The identification of subgroups of patients with asthma who respond to CysLT1 receptor antagonists is relevant for asthma management, as the response to these drugs is variable. The potential anti-remodeling effect of CysLT1 receptor antagonists might be important for preventing or reversing airway structural changes in patients with asthma. This review discusses the role of LTs in asthma and the therapeutic implications of the pharmacological modulation of the LT pathway for asthma.

    Several studies have outlined a possible relationship between an increased body mass index (BMI) and asthma. The aim of the study was to investigate in patients with asthma, enrolled in a real-life setting, a possible relationship between BMI and asthma parameters, including lung function markers (i.e., forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1], FEV1/FVC ratio, and forced expiratory flow at 25-75%), fractional concentration of exhaled nitric oxide (FeNO), asthma control level, Asthma Control Test (ACT), comorbid allergy, and allergic rhinitis (AR). The study included 286 patients with asthma. All subjects were evaluated performing clinical examination, spirometry, FeNO measurement, and ACT questionnaire. Ninety-six (33.6%) patients were overweight and 45 (14.1%) patients were obese. Lung function was significantly impaired in overweight and obese asthmatic patients in comparison with normal-weight ones. Increased BMI did not affect FeNO values and asthma control level. Overweight patients had double the risk (odds ratio [OR], 1.89) and obese patients had triple the risk (OR, 3.17) of having pathological FEV1 in comparison with normal-weight patients. Both in overweight (OR, 2.415) and obese patients (OR, 2.126), the risk to have pathological FEV1/FVC was about two times higher than in normal-weight patients. In overweight and obese asthmatic patients the probability of allergy was, respectively, 3.5 times (OR, 0.285) and 4.5 times (OR, 0.224) lower compared with normal-weight asthmatic patients. The risk of suffering from AR was three times lower in overweight (OR, 0.331) patients and six times lower in obese (OR, 0.163) patients. The present study suggests that BMI assessment should be routinely considered in asthmatic patients to reveal bronchial obstruction, also, in controlled asthma. PMID:24992544

Aims: To investigate the association between irritable bowel syndrome (IBS and asthma, and explore the symptoms of IBS among asthma patients in Kuwait. Settings and Design: Case control study. Methods: In a tertiary center, for allergy and asthma, 138 patients aged 20-65 years, with asthma, diagnosed clinically and by spirometry,were compared with 145 healthy, non-asthmatic controls matched for age, gender and nationality. Cases and controls completed a self-administered questionnaire of irritable bowel syndrome diagnosis (ROME II criteria. Statistical Analysis Used: The data were analyzed using SPSS software, and proportions were tested with Chi-square or Fisher′s test. Odds ratio (OR with 95% Confidence Interval (CI were calculated to identify the associated risk factors. The demographic variables were selected for logistic regression analysis. Results : A significantly large proportion (39.13% of asthmatics had IBS as compared to 7.93% controls (P < 0.001. A higher proportion of females with IBS were observed in cases and controls (74%, 61.54%. IBS was seen in 87% cases using inhalers, and in 13% with additional oral theophylline (P < 0.001. As many as 66.6% cases, had IBS with relatively short duration of asthma (1-5 years, P < 000. Predominant symptoms of IBS in asthmatics were abdominal discomfort or distension (64.8% vs. 11.5%, (P < 0.000, OR = 14.1; 95%CI: 3.748-53.209, bloated feeling of abdomen (74.1% vs. 34.62% (P < 0.001, OR = 5.38; 95%CI:1.96-14.84, increased frequency of stools (63%, P < 0.006. Conclusions: Irritable bowel syndrome in asthmatics was significantly high, more in the female asthmatics. Abdominal discomfort, persistent bloated feeling, increased frequency of passing stools were the most common IBS symptoms observed.

    Teleophthalmology is gaining importance as an effective eye care delivery modality worldwide. In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP). Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR), glaucoma, age-related macular degeneration (ARMD), and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time. Considering the improved quality of patient care and patient satisfaction reported for these telemedicine services, this review explores how teleophthalmology helps to improve patient outcomes.

    This paper describes several approaches for implementing quality improvement initiatives to improve patient satisfaction, which enables health-care organizations to position themselves for success in today's global and increasingly competitive environment. Specifically, measuring the views of patients, improving patient satisfaction through a community-wide effort, and using a Six Sigma program are discussed. Each of these programs can be an effective mechanism for quality improvement. A key component to quality improvement techniques involves collaborative efforts by all health-care professionals and managers as they seek to increase patient satisfaction. PMID:15552388

    Full Text Available Abstract Background The prevalence of Gastroesophageal Reflux Disease (GERD in Turkey is reported as 11.6%. Studies of pulmonary function in asthmatics have demonstrated a correlation between lung resistance and the occurrence of spontaneous gastroesophageal reflux. Few studies have included measures of lung diffusing capacity for carbon monoxide. The aim of this study is to assess whether asthma patients had worse lung function and gas diffusion according to diversity of GERD symptoms they concurrently experienced. The secondary aim of the study is to determine the frequency and different faces of GERD in our asthma patients compared to healthy controls. Methods Sixty consecutive asthma patients evaluatd at the pulmonary specialty outpatient clinic were included in the study. The control group included 60 healthy volunteers who had normal pulmonary function and routine laboratory tests. A modified version of a self-reported questionnaire developed by Locke and associates at the Mayo Clinic was conducted face-to-face with consecutive asthma patients and control subjects. Pulmonary function measurements were taken using spirometry. DLCO (mL/dk/mmHg and DLCO/VA (DLCO adjusted according to alveolar volume were measured using a single-breath technique. Statistical analyses were performed using the SPSS 17.0 statistical software. Results DLCO and DLCO/VA were significantly lower in asthma patients who had dysphagia symptoms. Frequent and significant acid regurgitations were seen in 28.33% (n = 17 of patients in the study group and 6.7% (n = 4 of patients in the control group. Severe, troublesome heartburn symptoms were reported by 28.2% (n = 17 of patients in the study group and 16.7% (n = 10 of subjects in the control group. Dysphagia was detected in 38.3% (n = 23 of all asthma cases and in 1.7% (n = 1 of the subjects in the control group. Conclusions There were many faces of gastroesophageal reflux disease in our asthmatic

    Full Text Available BACKGROUND: 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. METHODS: 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. RESULTS: The proportions of total control (ACT = 25, well controlled (ACT = 20-24, and poorly controlled (ACT 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. CONCLUSIONS: Periodical exercise and raw vegetable intake are associated with good asthma control in Japanese patients.

    Full Text Available Normal human breathing exhibits complex variability in both respiratory rhythm and volume. Analyzing such nonlinear fluctuations may provide clinically relevant information in patients with complex illnesses such as asthma. We compared the cycle-by-cycle fluctuations of inter-breath interval (IBI and lung volume (LV among healthy volunteers and patients with various types of asthma. Continuous respiratory datasets were collected from forty age-matched men including 10 healthy volunteers, 10 patients with controlled atopic asthma, 10 patients with uncontrolled atopic asthma, and 10 patients with uncontrolled non-atopic asthma during 60 min spontaneous breathing. Complexity of breathing pattern was quantified by calculating detrended fluctuation analysis, largest Lyapunov exponents, sample entropy, and cross-sample entropy. The IBI as well as LV fluctuations showed decreased long-range correlation, increased regularity and reduced sensitivity to initial conditions in patients with asthma, particularly in uncontrolled state. Our results also showed a strong synchronization between the IBI and LV in patients with uncontrolled asthma. Receiver operating characteristic (ROC curve analysis showed that nonlinear analysis of breathing pattern has a diagnostic value in asthma and can be used in differentiating uncontrolled from controlled and non-atopic from atopic asthma. We suggest that complexity analysis of breathing dynamics may represent a novel physiologic marker to facilitate diagnosis and management of patients with asthma. However, future studies are needed to increase the validity of the study and to improve these novel methods for better patient management.

    Full Text Available Asthma is a major public health problem affecting a large number of individuals of all ages. The effectiveness of medications depends not only on the efficacy and appropriateness of the drugs used, but also on patient adherence to the intended regimen. Adherence with medication regimens is essential for attaining maximal therapeutic benefits. The main objective of the study was to assess the medication adherence and to identify the reasons for non-adherence to prescribed therapy. The medication adherence was assessed by using Morisky Medication Adherence Assessment questionnaires. Assessment of patient’s adherence from baseline to first follow up showed a mean increase in medication adherence level of 2.735 ± 0.1762 and P < 0.0001 which is statistically significant. Assessment of patient’s adherence from baselines to second follow up shows a mean increase of 3.211 ± 0.172 and P < 0.0001 which is statistically significant. The study concludes that pharmacist provided patient counseling found to have significant influence on improvement in the patient’s adherence to prescribed therapy.

    Full Text Available Abstract Background Buffer analyses have shown that air pollution is associated with an increased incidence of asthma, but little is known about how air pollutants affect health outside a defined buffer. The aim of this study was to better understand how air pollutants affect asthma patient visits in a metropolitan area. The study used an integrated spatial and temporal approach that included the Kriging method and the Generalized Additive Model (GAM. Results We analyzed daily outpatient and emergency visit data from the Taiwan Bureau of National Health Insurance and air pollution data from the Taiwan Environmental Protection Administration during 2000–2002. In general, children (aged 0–15 years had the highest number of total asthma visits. Seasonal changes of PM10, NO2, O3 and SO2 were evident. However, SO2 showed a positive correlation with the dew point (r = 0.17, p 2 concentration had the highest impact on asthma outpatient visits on the day that a 10% increase of concentration caused the asthma outpatient visit rate to increase by 0.30% (95% CI: 0.16%~0.45% in the four pollutant model. For emergency visits, the elevation of PM10 concentration, which occurred two days before the visits, had the most significant influence on this type of patient visit with an increase of 0.14% (95% CI: 0.01%~0.28% in the four pollutants model. The impact on the emergency visit rate was non-significant two days following exposure to the other three air pollutants. Conclusion This preliminary study demonstrates the feasibility of an integrated spatial and temporal approach to assess the impact of air pollution on asthma patient visits. The results of this study provide a better understanding of the correlation of air pollution with asthma patient visits and demonstrate that NO2 and PM10 might have a positive impact on outpatient and emergency settings respectively. Future research is required to validate robust spatiotemporal patterns and trends.

    The wave of digital health is continuously growing and promises to transform healthcare and optimize the patients' experience. Asthma is in the center of these digital developments, as it is a chronic disease that requires the continuous attention of both health care professionals and patients themselves. The accurate and timely assessment of the state of asthma is the fundamental basis of digital health approaches and is also the most significant factor toward the preventive and efficient management of the disease. Furthermore, the necessity of inhaled medication offers a basic platform upon which modern technologies can be integrated, namely the inhaler device itself. Inhaler-based monitoring devices were introduced in the beginning of the 1980s and have been evolving but mainly for the assessment of medication adherence. As technology progresses and novel sensing components are becoming available, the enhancement of inhalers with a wider range of monitoring capabilities holds the promise to further support and optimize asthma self-management. The current article aims to take a step for the mapping of this territory and start the discussion among healthcare professionals and engineers for the identification and the development of technologies that can offer personalized asthma self-management with clinical significance. In this direction, a technical review of inhaler based monitoring devices is presented, together with an overview of their use in clinical research. The aggregated results are then summarized and discussed for the identification of key drivers that can lead the future of inhalers. PMID:26919553

  7. Risk of Obstructive Sleep Apnea in Adult Patients with Asthma: A Population-Based Cohort Study in Taiwan.

    Te-Chun Shen

    Full Text Available There are several publications reported that obstructive sleep apnea (OSA was associated with asthma. However, large-scaled, population-based cohort study has been limited. We aimed to examine the risk of OSA among adult patients with asthma in an Asian population.We conducted a retrospective cohort study using data from the National Health Insurance (NHI of Taiwan. The asthma cohort included 38,840 newly diagnosed patients between 2000 and 2010. The date of diagnosis was defined as the index date. Each patient was randomly matched with four people without asthma according to gender, age, and the index year as the comparison cohort. The occurrence of OSA was followed up until the end of 2011. The risk of OSA was estimated using the Cox proportional hazard model after adjusting for gender, age, and comorbidities.The overall incidence of OSA was 2.51-fold greater in the asthma cohort than in the comparison cohort (12.1 versus 4.84 per 1000 person-years. Compared to non-asthma subjects, the adjusted hazard ratio (aHR of OSA increased to 1.78 for asthma patients with one or less annual emergency room (ER visit, and 23.8 for those who visited ER more than once per year. In addition, aHR in patients with inhaled steroid treatment compared to those without steroid treatment was 1.33 (95% CI = 1.01-1.76.Patients with asthma have a significantly higher risk of developing OSA than the general population. The results suggest that the risk of OSA is proportional to asthma control and patients with inhaled steroid treatment have a higher risk for OSA than those without steroid treatment.

    2014-03-01

    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. Special regulatory role of eicosanoids has been postulated in aspirin-induced asthma. Objective. To investigate effects of aspirin on exhaled breath condensate (EBC levels of eicosanoids in patients with asthma. Methods. We determined EBC eicosanoid concentrations using gas chromatography/mass spectrometry (GC-MS and high-performance liquid chromatography/mass spectrometry (HPLC-MS2 or both. Determinations were performed at baseline and following bronchial aspirin challenge, in two well-defined phenotypes of asthma: aspirin-sensitive and aspirin-tolerant patients. Results. Aspirin precipitated bronchial reactions in all aspirin-sensitive, but in none of aspirin-tolerant patients (ATAs. At baseline, eicosanoids profile did not differ between both asthma groups except for lipoxygenation products: 5- and 15-hydroxyeicosatetraenoic acid (5-, 15-HETE which were higher in aspirin-induced asthma (AIA than inaspirin-tolerant subjects. Following aspirin challenge the total levels of cysteinyl-leukotrienes (cys-LTs remained unchanged in both groups. The dose of aspirin had an effect on magnitude of the response of the exhaled cys-LTs and prostanoids levels only in AIA subjects. Conclusion. The high baseline eicosanoid profiling of lipoxygenation products 5- and 15-HETE in EBC makes it possible to detect alterations in aspirin-sensitive asthma. Cysteinyl-leukotrienes, and eoxins levels in EBC after bronchial aspirin administration in stable asthma patients cannot be used as a reliable diagnostic index for aspirin hypersensitivity.

  12. Exercise training in asthma.

    Asthma is a chronic disease that is often limiting the exercise capacity. Rehabilitation programs are recommended and widely applied in asthmatic patients, and exercise prescription is a keystone of these programs. The impairment of exercise performance in asthmatics, the role of exercise training in such patients, the mechanisms of its beneficial effects and the suggested programs are discussed in a review, accordingly to the current evidence and available data in scientific literature. Exercise performance is impaired in most asthmatics. There is no conclusive evidence that asthma may involve a ventilatory limitation to exercise. The lesser fitness in asthmatics seems mainly due to inactivity and sedentary lifestyle. Exercise induced asthma (EIA) is a significant problem, and the best approach to minimise its effects on exercise capacity is prevention. Exercise training has been proved to have health-related benefits and to improve the quality of life. There is substantial evidence that exercise training increases exercise performance and fitness in asthmatics. It is still unclear whether physical training improves pulmonary function and bronchial responsiveness. Since asthma ranges widely, exercise prescription varies for each patient. The proper selection of the patients and the choice of exercise programs are the steps required. Accordingly with the severity of the disease, exercise strategies may range from sports activities to, when the disease is severe, inpatient hospital programs that overlap with COPD rehabilitation. Further research to clarify some aspects (effects on pulmonary function and EIA, outcomes, cost-benefit relationship) is necessary. PMID:11296996

    Objective. Atopie asthma provides a usetul model for evaluating the genetic tactors that control human immune responsiveness. HLA class Ⅱ gene products are involved in the control of immune response. As HLA-DRB gene is the most polymorphic HLA class Ⅱ gene, we investigated whether susceptibility or resistance to the disease is associated with HLA-DRB. Methods. Blood samples were obtained from two groups of unrelated Chinese northern adults: (1) 50 atopic asthma (7 of them with familial aggregation) ; (2) 80 healthy controls without asthma or atopy and other HLA-associated diseases. Genomic DNA was extracted from peripheral venous blood leucocytes. The polymorphie second exon of HLA-DRB gene was amplified by sequence-specific primer polymerase chain reaction (SSP/PCR) methods. All patients had their serum IgE(total and spscifie) antibody levels by RAST, bronchial reactivity assessed by methaeholine brocho-provocation test and/or hronchodilation test. Results.There was an increased gene frequency of DR52 and DR52 in asthmatic subjects compared with healthy subjects(17% vs 4.3%, P<0. 01% 50% vs 17.5%, P<0. 01), and the decreased frequency of DR2(15) and DR52 in asthmatic patients(7% vs 18%, P<0. 05; 2% vs 33%, P<0. 01). We found the positive association between DR5(13)-DR52 and sIgE antibody responsiveness to d1 (from house dust mite allergen ); negative association between HLA-DRB alleles and TIgE or BHR ( bronchial hyperresponsiveness). Conclusion. The results suggested that HLA haplotype DR6(13)-DR52 was significantly implicated in suseeptibility to house dust mite induced-asthma, at least it would he more closely assocaated with atopic asthms. Conversely, alleles DR2(15) and DR51 might corder protection against the disease. HLA-DRB genes were particularly involved in regulating human atopie immune response in asthma.

A randomized and prospective study was undertaken to find out the efficacy of montelukast as add on to β2-agonist and inhaled corticosteroids in patients of moderate persistent asthma. Methods: This was a continuous, longitudinal, prospective study carried out at a tertiary care teaching hospital. Newly diagnosed patients of moderate persistent asthma attending the chest out patient department (OPD were enrolled. Group I was treated with salbutamol 200 mcg rotacap SOS and formoterol 6 mcg + budesonide 400 mcg rotacap BD. In addition to these medicines group II also received montelukast 10 mg OD. The patients were followed up every two months. Clinical examination and pulmonary function tests (PFT were carried out at baseline and during each visit. Unpaired 't' test was used for statistical analysis. Results: Comparison of clinical symptoms revealed a better improvement in group II as compare to group I [cough - 83% vs. 33%; breathlessness - 75% vs. 33%; and wheezing - 83% vs. 78%] at the end of one year. A significantly better (p < 0.05 improvement in forced expiratory volume (FEV1 was also observed in group II. Conclusions: Treatment with montelukast leads to better improvement in clinical symptoms and PFT in the patients of moderate persistent asthma. [Int J Basic Clin Pharmacol 2012; 1(2.000: 91-101

    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)

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)

    Full Text Available The aim of the present study was to find out efficacy of cognitive behavior therapy, as an adjunct to standard pharmacotherapy, in bronchial asthma. In a random-ized two-group design with pre-and post assessments, forty asthma patients were randomly allotted to two groups: self management group and cognitive behavior therapy group. Both groups were exposed to 6-8 weeks of intervention, asthma self management program and cognitive behavior therapy. Assessment measures used were-Semi structured interview schedule, Asthma Symptom Checklist, Asthma di-ary, Asthma Bother Profile, Hospital Anxiety & Depression Scale, AQLQ and Peak Expiratory Flow Rate. Within group comparison showed significant improvement in both groups at the post assessment. Between group comparisons showed that CBT group reported significantly greater change than that of SM group. Cognitive behavior therapy helps in improving the managment of asthma.

    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.

    Background Although recent metagenomic approaches have characterized the distinguished microbial compositions in airways of asthmatics, these results did not reach a consensus due to the small sample size, non-standardization of specimens and medication status. We conducted a metagenomics approach by using terminal restriction fragment length polymorphism (T-RFLP) analysis of the induced whole sputum representing both the cellular and fluid phases in a relative large number of steroid naïve asthmatics. Methods Induced whole sputum samples obtained from 36 healthy subjects and 89 steroid-naїve asthma patients were analyzed through T-RFLP analysis. Results In contrast to previous reports about microbiota in the asthmatic airways, the diversity of microbial composition was not significantly different between the controls and asthma patients (p=0.937). In an analysis of similarities, the global R-value showed a statistically significant difference but a very low separation (0.148, p=0.002). The dissimilarity in the bacterial communities between groups was 28.74%, and operational taxonomic units (OTUs) contributing to this difference were as follows: OTU 789 (Lachnospiraceae), 517 (Comamonadaceae, Acetobacteraceae , and Chloroplast), 633 (Prevotella), 645 (Actinobacteria and Propionibacterium acnes), 607 (Lactobacillus buchneri, Lactobacillus otakiensis, Lactobacillus sunkii, and Rhodobacteraceae), and 661 (Acinetobacter, Pseudomonas, and Leptotrichiaceae), and they were significantly more prevalent in the sputum of asthma patients than in the sputum of the controls. Conclusion Before starting anti-asthmatic treatment, the microbiota in the whole sputum of patients with asthma showed a marginal difference from the microbiota in the whole sputum of the controls.

    Full Text Available 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.

Results The levels of IFN-γ, IL-17 and IL-33 in general treatment group and inhaling treatment group before treatment were higher than those in control group (P<0. 05), but the PEF and FEV1/ FVC were lower (P<0. 05). After treatment the levels of IL-33 and IL-17 in inhaling treatment groups weredecreased than before treatment (P<0. 05) , but the PEF and FEV1/FVC were increased (P<0. 05) ; the levels of IL-33 and IL-17 in treatment group were lower after treatment than those in general treatment group, but the PEF and FEV1/FVC were higher. No statistical significance in the level of IFN-y was found between before and after treatment in general treatment group and inhaling treatment group. Conclusion The levels of IFN- y, IL-17 and IL-33 are significantly increased in patients with bronchial asthma; budesonide and formoterol inhaling can decrease the levels of IL-17 and IL-33, and improve the pulmonary function.

  1. Building patient relationships: a smartphone application supporting communication between teenagers with asthma and the RN care coordinator.

    Haze, Kimberly A; Lynaugh, Jillian

    2013-06-01

    Smartphone applications used in healthcare are emerging as an adjunct therapy to assist patients in self-management. Often, smartphone technology is not integrated into healthcare delivery and does not build the nurse-patient relationship, an essential mechanism to guide the patient toward health. In a pilot study using smartphones with teenagers with asthma, the application provided a method not only to share health information at the point-of-living, including health assessments, personalized health plans, and disease information, but also to allow text messaging communication between the teenager and his/her RN care coordinator. Twenty-five teenagers piloted the smartphone application and provided feedback about its use. Eighty-five percent of the teenagers responding to the end-of-pilot, semistructured interview indicated a positive change in the nurse-patient relationship. Teenagers perceived that they could ask more questions along with having improved access and quicker response times. The RN care coordinators perceived improved ability to contact teenagers and improved accuracy of assessment data. Although the pilot had several limitations, it demonstrates that smartphone technology and text messaging can further the nurse-patient relationship. For this to occur, nurses need to become involved in the development and integration of technology to focus applications on innovative ways to enhance communication in patient care. PMID:23728445

    This paper describes the translation to Castilian and adaptation of a quality of life measurement instrument: the Asthma Quality of Life Questionnaire (AQLQ). The AQLQ, developed by Juniper et al, contains 32 items, 5 of which relate to habitual activities that the patient can choose from among a list of 26 possibilities. Answers are given on a scale of 7 points. To adapt this instrument for use in Spain, we subjected it to a process of translation/back translation by bilingual informants. The translated and original versions of each item, activity and answer option were evaluated as being totally equivalent (A), fairly equivalent but with some questionable wording (B), or of questionable equivalence (C). The naturalness and correctness of the Spanish version were also evaluated on a scale of 1 to 10. Three (9%) items and 1 (4%) activity were considered to be of questionable equivalence (C) and 12 (37%) items and 1 activity (4%) were considered to be of type B equivalence. The questionable aspects of types B and C equivalence were discussed in 2 meetings, along with expressions that were equivalent but unnatural or grammatically incorrect; the first meeting involved researchers and translators and the second was held with a group of 6 asthmatics. Consensus was finally obtained for each item and activity included in the second draft. That draft was then administered to another group of 7 patients in order to check comprehension and equivalence, after which a definitive version was produced by the researchers.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7788083

    Ornamental plants (OPs) can lead to immediate-type sensitization and even asthma and rhinitis symptoms in some cases. This study aimed to evaluate sensitization to OPs in patients with asthma and/or allergic rhinitis and to determine the factors affecting the rate of sensitization to OPs. A total of 150 patients with asthma and/or allergic rhinitis and 20 healthy controls were enrolled in the study. Demographics and disease characteristics were recorded. Skin-prick tests were performed with a standardized inhalant allergen panel. Skin tests by "prick-to-prick" method with the leaves of 15 Ops, which are known to lead to allergenic sensitization, were performed. Skin tests with OPs were positive in 80 patients (47.1%). There was no significant difference between OP sensitized and nonsensitized patients in terms of gender, age, number of exposed OPs, and duration of exposure. Skin test positivity rate for OPs was significantly high in atopic subjects, patients with allergic rhinitis, food sensitivity, and indoor OP exposure, but not in patients with pollen and latex allergy. Most sensitizing OPs were Yucca elephantipes (52.5%), Dieffenbachia picta (50.8%), and Euphorbia pulcherrima (47.5%). There was significant correlation between having Saintpaulia ionantha, Croton, Pelargonium, Y. elephantipes, and positive skin test to these plants. Sensitivity to OPs was significantly higher in atopic subjects and patients with allergic rhinitis, food allergy, and indoor OP exposure. Furthermore, atopy and food sensitivity were found as risk factors for developing sensitization to indoor plants. Additional trials on the relationship between sensitization to OPs and allergic symptoms are needed. PMID:24717779

    We examined systematically all controlled and cross-over randomised trials in patients with acute exacerbations of asthma and chronic obstructive pulmonary disease comparing Heliox against air-oxygen mixtures. Fourteen studies were identified. In asthma studies, peak expiratory flow rate (PEFR) was increased by an average of 29.6% (95% CI 16.6-42.6) by Heliox-driven nebulisers, or by 13.3 l.min(-1) (95% CI 3.71-22.81) absolute. In studies of patients with chronic obstructive pulmonary disease receiving non-invasive ventilation the arterial carbon dioxide tension (P(a)co(2)) and respiratory rate were unchanged: weighted mean difference for P(a)co(2)-0.29kPa (95% CI - 0.64-0.07) favoured Heliox, and for respiratory rate 1.6 breaths.min(-1) (95% CI - 0.93, 4.14) favoured control. Heliox minimally reduced the work of breathing in intubated patients, and reduced intrinsic positive end expiratory pressure (iPEEP). The use of Heliox to drive nebulisers in patients with acute asthma slightly improves airflow measures. We were unable to determine whether this improved recovery. PMID:17156225

    Cryptococcus neoformans is an opportunistic fungal pathogen that causes lung inflammation and meningoencephalitis in immunocompromised patients but is also able to asymptomatically infect immunocompetent individuals. C. neoformans is found ubiquitously especially in urban areas where it is spread by pigeons, and fungal exposure may predispose for asthma development already at an early age, as soon as confronted with pigeon droppings. In the study presented here, we investigated the presence of specific immunoglobulin G (IgG) against C. neoformans in sera from patients suffering from asthma in comparison to a healthy control cohort, accrued from the Leipzig Research Centre for Civilization Diseases (LIFE). For serological analysis we developed a flow cytometry (FACS) based assay specific for an acapsular strain of C. neoformans to comprehensively analyze different cryptococcal serotypes. Compared with the non-asthmatic cohort, asthmatics exhibited, as expected, an elevated level of total serum immunoglobulin E (IgE), whereas the IgG seroreactivity against C. neoformans was not significantly different among the two groups (P = .118). Nevertheless, there was a trend toward increased Cryptococcus-specific IgG antibodies in the serum of asthmatics. Additionally, in male asthmatics an increased IgG-mediated seroreactivity compared to female asthmatics was found. This points to a higher prevalence of subclinical C. neoformans infection in male asthmatics and may support the hypothesis of C. neoformans as a risk factor for the development of asthma in urban areas.

    Full Text Available Background and Objectives: Asthma is a chronic respiratory disease characterized by reversible contraction of airways. Coping strategies can reduce the negative impact of the disease in individuals or cause incompatible behaviors by negative effect. This study aimed to evaluate the religious coping strategies in asthma patients and the relationship of religious coping and general health. Methods: The study included 102 asthmatic patients referred to the pulmonary clinic of Shahid Beheshti hospital of Qom. Brief religious coping strategy questionnaire and the general health questionnaire were used in this study. Results: The mean positive religious coping strategy was 26.24±9.89 and 60% of the patients had higher than average scores. The mean negative religious coping strategy was 10.56±3.99 and 35% of patients had a mean score higher than average scores. The mean total general health score was 23.91±11.9. Conclusion: The study results showed that asthmatic patients are at greater risk of depression and a negative correlation exists between positive religious coping and general health scores. It can be concluded that in asthmatic patients, depression should be suspected sooner. Also, during the course of treatment and in cases of resistant to treatment, this issue should be considered. It can be concluded that the patients who use more positive coping strategies and have a strong spiritual beliefs may have higher mental health that leads to higher physical health and a better response to treatment.

    Full Text Available Objective: To evaluate the frequency and predictability of side effects, including tremor, cramp, and palpitation, due to treatment in patients with chronic obstructive pulmonary disease and asthma. Methods: We prepared a standard questionnaire for 299 patients concerning their diagnosis, treatment, and side effects of the treatment in February 2007 at Hacettepe University, Faculty of Medicine, Department of Pulmonary Diseases. We prospectively examined the clinical status of the patients and side effects of the treatment at the 15th, 30th, and 180th days of the treatment. Results: In our study, there were 38 (12.7% patients with drug-induced tremor. Of these, 27 (71.1% had asthma (p=0.004 and 18 (47.4% had anamnestic palpitation. Drug-induced tremor risk was 15.3 times higher in patients who used a beta-mimetic compared with those who used any drugs. Cramp risk increased with beta-mimetic use only. In our study, drug-induced tremor was still present at the 180th day of examination in 32 (84.2% patients. Conclusion: This study demonstrated that side effects, including tremor, palpitation, and cramp, were more common in our patients compared with those in other studies. These side effects were directly related to the primary disease and the use of beta-2-agonists. Another finding of our study is that tolerance did not develop as much as that reported in literature.

    Full Text Available Füsun Yildiz, On behalf of the ASIT Study Group Department of Pulmonary Disease, Kocaeli University School of Medicine, Kocaeli, Turkey Background: Despite the availability of new pharmacological options and novel combinations of existing drug therapies, the rate of suboptimal asthma control is still high. Therefore, early identification of the clinical and behavioral factors responsible for poor asthma control, and interventions during routine outpatient visits to improve asthma trigger management, are strongly recommended. This study was designed to evaluate the profiles of asthmatic patients and their inhaler treatment devices in relation to asthma control in Turkey. Methods: A total of 572 patients with persistent asthma (mean [standard deviation] age: 42.7 [12.1] years; 76% female were included in this prospective observational study. A baseline visit (0 month, visit 1 and three follow-up visits (1, 3 and 6 months after enrolment were conducted to collect data on demographics, past medical and asthma history, and inhaler device use. Results: Asthma control was identified in 61.5% of patients at visit 1 and increased to 87.3% at visit 4 (P < 0.001, regardless of sociodemographics, asthma duration, body mass index or smoking status. The presence of asthma-related comorbidity had a significantly negative effect on asthma control (P = 0.004. A significant decrease was determined, in the rate of uncontrolled asthma, upon follow-up among patients who were using a variety of fixed dose combination inhalers (P < 0.001 for each. Logistic regression analysis was used to show that the presence of asthma-related comorbidity (odds ratio [OR], 0.602; 95% confidence interval [CI], 0.419; 0.863, P = 0.006 and active smoking (OR, 0.522; 95% CI, 0.330; 0.825, P = 0.005 were significant predictors of asthma control.

  15. Application of the autoblood treated by preliminary extracorporeal X-ray irradiation in the therapy of bronchial asthma patients

    International Nuclear Information System (INIS)

    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

    Full Text Available Although the main goal of asthma management guidelines is to achieve and maintain clinical control, reported levels of not well-controlled asthma remain high. The aim of this analysis was to compare the levels of asthma control and the associated impact on patients' health status in Europe in 2006, 2008 and 2010. An additional outcome was the comparison of the burden of asthma with diabetes. Data were obtained from the cross-sectional, self-reported, European National Health and Wellness Surveys conducted in France, Germany, Italy, Spain and the UK. Asthma control (Asthma Control Test™; QualityMetric, Inc., Lincoln, RI, USA and health status (Short Form (SF-12 health survey and the Work Productivity Loss and Activity Impairment questionnaire were assessed. In 2010, the proportion of treated asthma patients assessed as having not well-controlled asthma was 53.5%, compared with 56.6% and 55.0% in 2008 and 2006, respectively. A significant reduction in not well-controlled asthma was observed in Germany between 2006 (72.3% and 2010 (62.5%; p=0.005. Fluctuations in control levels were observed in other countries. For all surveys, having at least well-controlled asthma was associated with a significantly lower number of healthcare contacts in the previous 6 months, better mean±sd SF-12 scores for the physical (data for 2010: not well controlled 39.9±11.38, at least well-controlled 48.0±9.89; p<0.001 and mental (data for 2010: not well-controlled 40.6±10.95, at least well-controlled 45.0±10.91; p<0.001 components, and significantly less impact on Work Productivity Loss and Activity Impairment. Asthma and diabetes were associated with a similar overall negative impact on health status. A substantial proportion of asthmatics remain not well-controlled across five European countries, resulting in a significant impact on health resources and patients' health status. The overall burden of asthma appears to be similar to that of diabetes.

    Full Text Available Abstract Background Since subepithelial fibrosis and protruded extracellular matrix are among the histological characteristics of polyps, the emilin/multimerin domain-containing protein 2 (EMID2 gene is speculated to be involved in the presence of nasal polyps in asthma and aspirin-hypersensitive patients. Methods To investigate the association between EMID2 and nasal polyposis, 49 single-nucleotide polymorphisms (SNPs were genotyped in 467 asthmatics of Korean ancestry who were stratified further into 114 aspirin exacerbated respiratory disease (AERD and 353 aspirin-tolerant asthma (ATA subgroups. From pairwise comparison of the genotyped polymorphisms, 14 major haplotypes (frequency > 0.05 were inferred and selected for association analysis. Differences in the frequency distribution of EMID2 variations between polyp-positive cases and polyp-negative controls were determined using logistic analyses. Results Initially, 13 EMID2 variants were significantly associated with the presence of nasal polyps in the overall asthma group (P = 0.0008-0.05, OR = 0.54-1.32 using various modes of genetic inheritance. Although association signals from 12 variants disappeared after multiple testing corrections, the relationship between EMID2_BL1_ht2 and nasal polyposis remained significant via a codominant mechanism (Pcorr = 0.03. On the other hand, the nominal associations observed between the genetic variants tested for the presence of nasal polyps in AERD (P = 0.003-0.05, OR = 0.25-1.82 and ATA (P = 0.01-0.04, OR = 0.46-10.96 subgroups disappeared after multiple comparisons, suggesting lack of associations. Conclusions These preliminary findings suggest that EMID2_BL1_ht2 may be a susceptibility marker of inflammation of the nasal passages among Korean asthma patients.

    Inhalative methacholine challenge (MC) was performed in 229 subjects presumed to suffer from occupational asthma due to exposure to airborne latex allergens (n = 62), flour (n = 28), isocyanates (n = 114), or irritants in hairdressers' salons (n = 25). They were also subjected to specific challenges with the occupational agents they were exposed to, completed a questionnaire using an abbreviated version of the ATS-DLD, and were interviewed by an experienced physician. Bronchial hyperresponsiveness in MC was defined by the results obtained in a previous study with 81 healthy volunteers. The threshold in these controls was set at a cumulative MC dose of 0.3 mg, corresponding to a sensitivity of 95%. The main purpose of the study was to investigate whether the MC and/or the occupational asthma case history are reliable predictors of the specific challenge test outcomes. In 40-72% of examined subjects, workplace-related asthma complaints occurred, with bronchial hyperreactivity in the MC ranging from 48% to 61%. However, only 12-25% demonstrated a significant bronchoconstructive reaction in the specific challenge test. MC results are only moderately associated with workplace-related asthma case histories. Positive outcomes of challenges with occupational agents are well correlated with positive MC results plus occupational asthma case histories. The combination of MC and occupational asthma case history shows a relatively high specificity (62%, 86%, 80%), but the sensitivity was moderately low (83%, 71%, 52%). MC sensitivities were 92%, 71%, and 62% (case histories of hairdressers were not available). We conclude that in most cases, occupational asthma (as defined by a specific challenge test response) is combined with bronchial hyperresponsiveness and workplace-related asthmatic symptoms. However, subjects of each exposure group demonstrated bronchial hyperresponsiveness and complained of workplace-related asthmatic symptoms, but occupational asthma could not be

    Patients with asthma may also have vocal cord dysfunction (VCD), which leads to poor control of the asthma. Once patients are diagnosed with difficult-to-treat asthma with poor control, VCD should be excluded or treated accordingly. The gold standard for diagnosis of VCD is to perform a laryngoscopy. However, this procedure is invasive and may not be suitable for patients with difficult-to-treat asthma. Four-dimensional (4D) dynamic volume computed tomography (CT) is a noninvasive method for quantification of laryngeal movement, and can serve as an alternative for the diagnosis of VCD. Herein, we present a series of five cases with difficult-to-treat asthma patients who were diagnosed with VCD by 4D dynamic volume CT. Clinicians should be alert to the possibility of VCD when poor control is noted in patients with asthma. Early diagnosis by noninvasive 4D dynamic volume CT can decrease excessive doses of inhaled corticosteroids. PMID:24246257

The titres found in both groups of patients showed no difference. Global evaluation revealed a high incidence of pulmonary autoantibodies. We saw a direct relationship between the titre and the degree of severity of the disease or the clinical condition. The demonstration of circulating pulmonary autoantibodies in bronchial asthma is possibly not only of diagnostic value but also of prognostic importance. PMID:135497

    Circadian rhythms of external respiration function (ERF) and body function (BF) were studied in 20 patients with mild bronchial asthma, 20 patients with bronchial asthma of medium gravity and in 14 healthy subjects. Circadian rhythms of the medium-group parameters of ERF were shown to be statistically insignificant, whereas individual circadian chronograms demonstrated circadian rhythms for all the patients with BA and healthy subjects. Essential differences were found in the organization of the temporary structure of circadian rhythms of ERF in BA patients and healthy subjects. It was discovered that in BA patients, the maximal pathological alterations develop within the period from the midnight to 8 a. m., whereas the minimal disorders of ERF are recorded within the period from the noon to 8 p. m. It is suggested that deterioration of bronchial patency which brings about the development of obstruction in BA patients is the result of hypersynchronization and increased amplitude of the circadian rhythms of those parameters of ERF which determine the bronchial patency.

    Full Text Available Abstract Background Exercise-induced bronchoconstriction (EIB is a highly prevalent condition, whose pathophysiology is not well understood. Endothelins are proinflammatory, profibrotic, broncho- and vasoconstrictive peptides which play an important role in the development of airway inflammation and remodeling in asthma. The aim of the study was to evaluate the changes in endothelin-1 levels in exhaled breath condensate following intensive exercise in asthmatic patients. Methods The study was conducted in a group of 19 asthmatic patients (11 with EIB, 8 without EIB and 7 healthy volunteers. Changes induced by intensive exercise in the concentrations of endothelin-1 (ET-1 in exhaled breath condensate (EBC during 24 hours after an exercise challenge test were determined. Moreover, the possible correlations of these measurements with the results of other tests commonly associated with asthma and with the changes of airway inflammation after exercise were observed. Results In asthmatic patients with EIB a statistically significant increase in the concentration of ET-1 in EBC collected between 10 minutes and 6 hours after an exercise test was observed. The concentration of ET-1 had returned to its initial level 24 hours after exercise. No effects of the exercise test on changes in the concentrations of ET-1 in EBC in either asthmatic patients without EIB or healthy volunteers were observed. A statistically significant correlation between the maximum increase in ET-1 concentrations in EBC after exercise and either baseline FENO and the increase in FENO or BHR to histamine 24 hours after exercise in the groups of asthmatics with EIB was revealed. Conclusion The release of ET-1 from bronchial epithelium through the influence of many inflammatory cells essential in asthma and interactions with other cytokines, may play an important role in increase of airway inflammation which was observed after postexercise bronchoconstriction in asthmatic patients.

    Full Text Available Annette Østergaard Jensen1, Gunnar Lauge Nielsen2, Vera Ehrenstein11Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, Denmark; 2Department of Medicine, Himmerland Hospital, Farsø, DenmarkObjective: Asthma diagnoses recorded in the Danish National Registry of Patients (DNRP are a misclassified measure of the actual asthma status. We quantified this misclassification and examined its impact on the results of an epidemiologic study on asthma.Study design and setting: We validated the DNRP asthma diagnoses against records of asthma diagnosed at medical examinations conducted during mandatory conscription evaluation. We had data on 22,177 male conscripts who were born from January 1st, 1977 to December 31st, 1983, in a conscription district in northern Denmark. We obtained asthma diagnoses recorded among the conscripts in the DNRP from January 1st, 1977 through December 31st, 2003. We estimated sensitivity, specificity, and positive predictive value (PPV of the DNRP asthma diagnoses. We then conducted sensitivity analysis to quantify the impact of nondifferential misclassification on the rate ratios measuring the association between asthma and risks of different skin cancers.Results: The sensitivity of the DNRP for detecting an asthma diagnosis was 0.44 (95% confidence interval [CI]: 0.42–0.47, the specificity was 0.98 (95% CI: 0.98–0.99 and the PPV was 0.65 (95% CI: 0.62–0.68. Both direct and inverse associations between asthma and the different types of skin cancers became more pronounced after correcting for the misclassification.Conclusion: The DNRP registered asthma diagnosis may be used to measure asthma status in epidemiologic studies seeking to estimate relative effects of asthma. Even at low values of DNRP sensitivity of asthma diagnoses were not sufficient to nullify observed relative associations in an actual dataset. The specificity of DNRP asthma diagnosis is high.Keywords: asthma, validity, registry data

    Full Text Available Objective : The present study was conducted to monitor adverse drug reactions in patients of bronchial asthma in outpatient department and inpatient department of a university teaching hospital in South Delhi. Materials and Methods : About 200 patients irrespective of age and sex with established asthma were interviewed during the time period of January 2006 to April 2006 using structured questionnaire. Naranjo′s adverse drug reaction probability scale was used to assess the adverse drug reactions. Results : A total of 15 adverse drug reactions were reported in 13 out of 200 asthmatic patients. Among the 13 patients reported with adverse drug reactions, 5 (38.5% were male and 8 (61.5% patients were female. Maximum percentage of ADRs (2 in 15 prescriptions, 13.3% observed with montelukast, followed by beclomethasone (1 in 12 prescriptions, 8.3%, salbutamol (6 in 109 prescriptions, 5.5%, and ipratropium (3 in 63 prescriptions, 4.8%. Conclusions : Montelukast was found to be associated with greater percentage of adverse drug reactions as compared to other antiasthamatics. The above findings are constrained by a small sample size and need to be corroborated by conducting long-term studies using a larger sample size.

    Objective: To study the relationship between Chlamydia pneumoniae (C. Pneumoniae) infection and asthma exacerbation. Methods: A prospective study of C. Pneumoniae infection was conducted in 75 patients with asthma and 63 patients with respiratory tract infection, and 100 blood donors served as controls.The presence of infection was convinced by the polymerase chain reaction and direct immunofluorescence assay for C. Pneumoniae DNA from throat swab specimens and micro-immunofluorescence testing for C. Pneumoniae-specific IgG, IgM and IgA antibodies. Results: Prevalence of specific IgG in asthma patients (81.3%) was higher than that of the blood donors (68. 0%, P<0. 05) and was not significantly different from respiratory tract infection patients (68. 0%, P>0. 05). The acute C. Pneumoniae infection rate of symptomatic asthma patients (59.4%) was markedly higher than that of respiratory tract infection patients (34.9%, P<0. 05). The average titer of C. Pneumoniae IgG instead of IgA in asthma patients (48. 38±6. 94)was significantly higher than respiratory tract infection patients (24. 70±8. 77, P<0. 05). Other pathogens were identified in 12 of 21 (57. 1%) asthma patients with C. Pneumoniae. The symptoms of 7 asthma patients with C. Pneumoniae infection were improved through antibiotic treatment. Conclusion: The findings suggest a possible role of C. Pneumoniae infection in asthma.

    Lucas, Sean R; Platts-Mills, Thomas A E

    2006-12-01

    None of the explanations proposed for the increase in paediatric asthma have been adequate. It is becoming apparent that the cause of the increase in asthma must be multi-factorial. Increasing attention has been focused on the role of lifestyle in the development of asthma. Lifestyle changes that have occurred in children are those in diet and decreased physical activity, with obesity being the product of these changes. The increase in asthma, obesity and a sedentary lifestyle have occurred together. However, a temporal relationship between asthma, obesity and decreased physical activity has not been determined in the paediatric literature. Limited data suggest that decreased physical activity could be playing a role in the aetiology of asthma independent of obesity. Furthermore, there has been substantial research on the benefits of exercise programmes for paediatric patients with asthma. Longitudinal trials monitoring physical activity, obesity and the development of asthma are needed. PMID:17098637

    Objective:To get a comprehensive understanding about the relationship between obstructive sleep apnea (OSA) and asthma by reviewing the epidemiology,pathophysiology,and clinical manifestation and then summarizing the latest progress on diagnosis and treatment.Data Sources:Articles referred in this review were mainly collected from a comprehensive search of the PubMed published in English from 1990 to 2015 with the terms "OSA" and “asthma'" as the main keywords.Highly regarded older publications were also included.Study Selection:Information about the features of the two diseases in common,the pathophysiologic association between them and their current treatments from the literature search were identified,retrieved,and summarized.Results:Both OSA and asthma are very prevalent conditions.The incidences of them have kept on rising in recent years.Asthma is often accompanied by snoring and apnea,and OSA often combines with asthma,as well.They have many predisposing and aggravating factors in common.Possible shared direct mechanistic links between them include mechanical effects,intermittent hypoxia,nerve reflex,inflammation,leptin,etc.Indirect mechanistic links include medication,nose diseases,smoking,obesity,and gastroesophageal reflux disease.Since OSA presents many similar features with nocturnal asthma,some scholars termed them as a sole syndrome "alternative overlap syndrome,"and proved that asthma symptoms in those patients could be improved through the treatment of continuous positive airway pressure.Conclusions:OSA and asthma are closely associated in pathogenesis,symptoms,and therapies.With the growing awareness of the relationship between them,we should raise our vigilance on the coexistence of OSA in those difficult-to-control asthmatic patients.Further studies are still needed to guide the clinical works.

    The impact of psychiatric illnesses upon asthma patients' functioning is not well understood. This study examined the impact of psychiatric comorbidity upon illness management in asthma patients using empirically-derived psychiatric comorbidity groups. Participants were a clinic sample of Greek-speaking asthma patients (N = 212) assessed using the Patient Health Questionnaire (PHQ) Somatoform, Depression, Panic Disorder (PD), Other Anxiety Disorder, Eating Disorder (ED) and Alcohol sub-scales. The associations between sub-scales were examined using multiway frequency analysis. The following groups were derived: Somatoform disorder and/or Any Depressive disorder (n = 63), Somatoform disorder and/or Other Anxiety disorder (n = 51), Somatoform disorder and/or Any ED (n = 60), and Any Anxiety group including PD and/or Other Anxiety disorder (n = 24). Across all groups, psychiatric illness was associated with significantly worse asthma control (p Anxiety group, OR = 4.61, 95% CI [1.90, 11.15], Somatoform and/or Any Depressive disorder, OR = 2.06, 95% CI [1.04, 4.09] and Somatoform and/or Other Anxiety disorder, OR = 2.75, 95% CI [1.35, 5.60] were at higher risk for asthma-related Emergency Room (ER) visits compared to controls. However only Somatoform and/or Any Depressive disorder, OR = 3.67, 95% CI [1.60, 8.72], Somatoform and/or Other Anxiety disorder, OR = 5.50, 95% CI [2.34, 12.74], and Somatoform and/or Any ED, OR = 4.98, 95% CI [2.14, 11.60] group membership were risk factors for asthma-related hospitalizations. Results suggest that while comorbid psychiatric disorders generally negatively impact asthma illness management, different psychiatric comorbidities appear to have disparate effects upon illness management outcomes.

    Full Text Available Aims: To investigate the relationship between asthma control, health related quality of life and subjective well-being in Czech adult patients with asthma. Design: A prospective observational cohort study. Methods: The sample included 316 people with asthma. In this 12-month observational study, patients were tested three times - at the baseline and after six and 12 months. Asthma control, health related quality of life and subjective well-being were assessed at the initial time point and followed up at six and 12 months by using the Asthma Control Test, the Mini Asthma Quality of Life Questionnaire and the Personal Well-being Index. Results: Level of asthma control and health related quality of life improved during the 12-month period, although spirometric parameters and subjective well-being were without significant change. Asthma control remained a significant predictor of health-related quality of life and general subjective well-being in linear regression models. Conclusions: Health-related quality of life is a construct based on a larger set of clinical variables when compared to subjective well-being. The regular monitoring of asthma control is associated with increased awareness and therapeutic expectations in patients, and better asthma control and health-related quality of life.

    National Committee for Quality Assurance recommends patient-centered medical homes incorporate input from patient populations; however, many health care organizations do not. This qualitative study used two open-ended questions from 148 active duty Army Soldiers and their family members to illicit recommendations for primary care providers and clinic leadership that would improve their health care experiences. Content analysis and descriptive statistics were used to analyze responses. Participant responses were related to four major themes: Access to Care, Interpersonal Interaction, Satisfaction of Care, and Quality of Care. Participants were overall satisfied with their care; however, spending less time waiting for appointments and to see the provider or specialist were the most frequently requested improvements related to Access to Care. For Interpersonal Interaction, 82% of the responses recommended that providers be more attentive listeners, courteous, patient, caring, and respectful. Decreasing wait times and improving interpersonal skills would improve health care experiences and patient satisfaction. PMID:27046182

  8. Beneficial effects of sitostanol on the attenuated immune function in asthma patients: results of an in vitro approach.

    Directory of Open Access Journals (Sweden)

    Florence Brüll

    Full Text Available BACKGROUND: In vitro and animal studies have suggested that plant sterols and stanols increase cytokine production by T-helper-1 cells. This may be beneficial for patient groups characterized by a T-helper-2 dominant immune response, e.g. asthma patients. (1 to evaluate whether sitostanol induces a T-helper-1 shift in peripheral blood mononuclear cells (PBMCs from asthma patients, and (2 to unravel the role of regulatory T-cells in this respect. METHODOLOGY/PRINCIPAL FINDINGS: PBMCs from 10 asthma patients and 10 healthy subjects were isolated and incubated with 1.2 µM sitostanol, while stimulated with 5 µg/ml PHA. Similar amounts of cholesterol were used to determine whether effects were specific for plant stanols or for sterols in general. Changes in cytokine production were measured using antibody arrays and ELISAs. Changes in regulatory T-cell population size were measured by flow cytometry, using intracellular Foxp3 staining. Sitostanol increased production of IFNγ by 6.5% and IL-2 by 6.0% compared to cholesterol (p<0.01. No changes in IL-4 and IL-13 were found. Interestingly, this effect was only present in PBMCs from asthma patients. The number of Foxp3+ cells tended to increase and their activity, measured by IL-10 production, increased after sitostanol treatment in PBMCs from asthma patients compared to controls by 32.3% (p = 0.077 and 13.3% (p<0.05, respectively. CONCLUSIONS/SIGNIFICANCE: Altogether, the sitostanol-induced Thelper-1 shift in PBMCs from asthma patients and the stimulating effects of sitostanol on Treg cell numbers and activity indicate a possible novel approach for plant stanol ester enriched functional foods in the amelioration of asthmatic symptoms. Functional effects, however, require further evaluation.

    2016-01-01

    Background Poor adherence to inhaled therapy is common in patients with asthma and COPD. An inhaler selection based on patients’ preference could be beneficial to adherence and treatment effectiveness. Properly designed questionnaires can assess patients’ satisfaction with their medication devices. The aim of this study was to estimate, using the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire, the ease of use and satisfaction of patients regarding three different marketed dry powder inhalers (DPIs): Diskus® (DK), Elpenhaler® (EH), and Turbuhaler® (TH). The FSI-10 is a self-completed questionnaire to assess patients’ opinions regarding ease of use, portability, and usability of devices, irrespective of the drug used. Patients and methods We performed a 4-week, open, noninterventional, multicenter, parallel clinical study in 560 asthmatic and 561 COPD patients. During the first visit, patients were classified into three groups according to the DPI they were already using. Patients were regularly receiving their treatments (Seretide DK, Rolenium EH, and Symbicort TH) and agreed to complete the FSI-10 questionnaire in the second visit. Results A total of 517 COPD and 523 asthma patients completed the study. All DPIs tested received satisfactory results, while the EH obtained consistently higher scores in the FSI-10 in both COPD and asthma patients (44.7 and 44.1 vs 41.5 and 43 for TH, 40.8 and 41.4 for DK, P<0.001 and P<0.01, respectively). TH was rated better than DK by asthma patients. Patients suffering with severe COPD tended to express higher feeling of satisfaction than those with moderate or mild disease, irrespective of the device used. Conclusion All DPIs tested were highly acceptable by asthma and COPD patients of different ages; nevertheless, EH received significantly higher ratings in most of the questionnaire domains. COPD patients in advanced stages of the disease generally expressed higher level of satisfaction with their devices.

    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.

    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

We hypothesized that improved air quality in North Carolina was associated with reduced rates of death from respiratory diseases in local populations. Materials and methods: We analyzed the trends of emphysema, asthma, and pneumonia mortality and changes of the levels of ozone, sulfur dioxide (SO2, nitrogen dioxide (NO2, carbon monoxide (CO, and particulate matters (PM2.5 and PM10 using monthly data measurements from air-monitoring stations in North Carolina in 1993–2010. The log-linear model was used to evaluate associations between air-pollutant levels and age-adjusted death rates (per 100,000 of population calculated for 5-year age-groups and for standard 2000 North Carolina population. The studied associations were adjusted by age group-specific smoking prevalence and seasonal fluctuations of disease-specific respiratory deaths. Results: Decline in emphysema deaths was associated with decreasing levels of SO2 and CO in the air, decline in asthma deaths–with lower SO2, CO, and PM10 levels, and decline in pneumonia deaths–with lower levels of SO2. Sensitivity analyses were performed to study potential effects of the change from International Classification of Diseases (ICD-9 to ICD-10 codes, the effects of air pollutants on mortality during summer and winter, the impact of approach when only

    Full Text Available Abstract Background Although patients have more problems using metered dose inhalers, clinical comparisons suggest they provide similar control to dry powder inhalers. Using real-life situations this study was designed to evaluate asthma control in outpatients with moderate to severe persistent asthma and to compare efficacy of fixed combinations of inhaled corticosteroids (ICS and long acting beta-agonists (LABA. Methods This real-life study had a cross-sectional design. Patients using fixed combinations of ICS and LABA had their asthma control and spirometry assessed during regular visits. Results 111 patients were analyzed: 53 (47.7% received maintenance therapy of extrafine beclomethasone-formoterol (BDP/F pressurized metered dose inhaler (pMDI, 25 (22.5% fluticasone-salmeterol (FP/S dry powder inhaler (DPI, and 33 (29.7% budesonide-formoterol (BUD/F DPI. Severity of asthma at time of diagnosis, assessed by the treating physician, was comparable among groups. Asthma control was achieved by 45.9% of patients; 38.7% were partially controlled and 15.3% were uncontrolled. In the extrafine BDF/F group, asthma control total score, daytime symptom score and rescue medication use score were significantly better than those using fixed DPI combinations (5.8 ± 6.2 vs. 8.5 ± 6.8; 1.4 ± 1.8 vs. 2.3 ± 2.1; 1.8 ± 2.2 vs. 2.6 ± 2.2; p = 0.0160; p = 0.012 and p = 0.025, respectively and the mean daily ICS dose were significantly lower. Conclusions pMDI extrafine BDP/F combination demonstrated better asthma control compared to DPIs formulated with larger particles. This could be due to the improved lung deposition of the dose or less reliance on the optimal inhalation technique or both.

    Full Text Available Introduction: Asthma and obesity are among diseases that cause several problems and impair quality of life.  The concurrence of these diseases, changes in the respiratory physiology, changes associated with obesity and limited activity associated with asthma may cause an interaction between the two conditions. Materials and Methods: We studied the epidemiologic characteristics of all recently diagnosed cases of asthma with no previous treatment who visited the Respiratory Diseases Clinic of the Ghaem Hospital from 2004 to 2007, their Body Mass Indexes (BMI were calculated and then spirometry was performed in all cases. Results: We studied 232 cases with the mean age of 38.96±12.94 years and the mean BMI of 27.05±4.92. Cough and exertional dyspnea were the most common clinical symptoms. In spirometric evaluations, the mean maximum mid-expiratory flow (MMEF increased with weight, which was not, however, insignificant. FVC in obese patients was significantly less than in normal weight cases. A significant correlation was not also seen between BMI and FEV1 (r=-0.023, P=0.729. Conclusion: Except for FVC which had a significant correlation with BMI, other studied indices yielded no significant results, which calls for more extensive studies with larger populations. Considering the fact that mild asthma is less common in obese patients, better weight control in asthmatic patients can promote their quality of life and make asthma management more effective.

    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.

  2. Application of adjusted subpixel method (ASM) in HRCT measurements of the bronchi in bronchial asthma patients and healthy individuals

    International Nuclear Information System (INIS)

    Background: Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). Objective: 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. Methods: 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. Results: 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%. Conclusions: 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.

  3. Review: Genetic diversity of HLA-DR and varion of asthma susceptibility; an overview of Asthma in Pregnancy

    Full Text Available Asthma is the most common potentially serious medical condition to complicate pregnancy. To date, many attempts have been done to detect genetic loci contributing to asthma susceptibility. HLA-DR loci may play an important role in the pathophysiology of allergic inflammation by influencing specific IgE responses. Asthma affects almost 7 percent of women in their childbearing years. When women with asthma become pregnant, a third of the patients improve, one third worsen, and the last third remain unchanged. Asthma exacerbations are most likely to appear during the weeks 24 to 36 of gestation, with only occasional patients (10 percent or fewer becoming symptomatic during labor and delivery. Uncontrolled asthma can cause serious complications for mother, including high blood pressure, toxemia and premature delivery. For the baby, complications of uncontrolled asthma include increased risk of stillbirth, fetal growth retardation, premature birth, low birth weight and a low APGAR score at birth. The goal management of asthma during pregnancy is to achieve optimal therapy, maintaining controlled asthma and increased the mother and baby’s quality of life. Most asthma medications are safe during pregnancy.

    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.

  7. The changes of IL-8, IL-10, IL-12 and IgE in serum of patients with asthma

    International Nuclear Information System (INIS)

    To evaluate the relationship and the clinical significance between the serum IL-8, IL-10, IL-12 and IgE in patients with asthma, the serum IL-8, IL-10 are measured by radioimmunoassay method and the serum IL-12, IgE by ELISA in 55 patients with asthma. The level of serum IL-8, IgE at stage of episode are significantly higher than that at stage of remission (P<0.01); the level of serum IL-10, IL-12 at stage of episode are significantly lower than that at stage of remission (P<0.01). Linear regression shows that the decrease of IL-12 relate to the increase of IgE. The results suggests that the change of the level of serum IL-8, IL-10, IL-12 and IgE could be a maker for the aggravation of asthma

    2015-01-01

    Purpose of review The aim of the present review is to discuss the epidemiology of inadequate asthma control with an examination of contributing environmental factors. Recent findings Despite advances in asthma therapies, a proportion of patients with asthma continue to have difficulty gaining adequate asthma control. Asthma severity and control in childhood is of particular importance as it translates to asthma morbidity in adulthood. Children with comorbid severe allergic rhinitis were more likely to have uncontrolled asthma. Recent data suggest that mouse allergen, more so than cockroach allergen, may be the most relevant urban allergen exposure. Tobacco smoke exposure, even passive exposure, leads to increased asthma symptoms and decreased response to inhaled corticosteroids. Efforts to ban smoking in public places have resulted in promising asthma results for entire populations. Energy saving efforts to tighten a home’s air leaks can lead to increased indoor pollutant levels and, therefore, must be accompanied by efforts to reduce, filter, or exchange indoor pollutants. Obesity is independently associated with decreased asthma control. Furthermore, the detrimental effects of pollutant exposure are enhanced in an overweight individual with asthma. Summary Lack of asthma control can be due to a complex web of factors including adherence, intrinsic factors, and environmental exposures. Further research on intervention strategies is needed to achieve improved rates of asthma control. PMID:26226354

    Viral exacerbations continue to represent the major burden in terms of morbidity, mortality and health care costs associated with asthma. Those at greatest risk for acute asthma are those with more severe airways disease and poor asthma control. It is this group with established asthma in whom acute exacerbations triggered by virus infections remain a serious cause of increased morbidity. A range of novel therapies are emerging to treat asthma and in particular target this group with poor disease control, and in most cases their efficacy is now being judged by their ability to reduce the frequency of acute exacerbations. Critical for the development of new treatment approaches is an improved understanding of virus-host interaction in the context of the asthmatic airway. This requires research into the virology of the disease in physiological models in conjunction with detailed phenotypic characterisation of asthma patients to identify targets amenable to therapeutic intervention.

    Full Text Available Background: The effect of mold fungi to allergic sensitization is not well-known. We aimed to evaluate the role of molds in the relation between indoor environment and atopy in asthmatics. Materials and Methods: The air samples obtained from 66 stable asthmatics and 35 control subject′s houses were sprayed into Sabouraud dextrose agar. Allergy skin testing were performed in both groups. The temperature and humidity of each house were measured. Results: The incidence of atopy was similar in cases (59.1% and controls (51.4%. The average amount of mold was 35.9 CFU/m 3 and 34.3 CFU/m 3 , respectively. The number of household residents was positively correlated with the amount of molds. There was no difference in the amount of mold with respect to dosage of inhaler corticosteroids as well as symptom levels in asthmatics. The most frequently encountered allergens were Dermatophagoides farinae/Dermatophagoides pteronyssinus, grass/weeds and molds. Spending childhood in a village was more common among atopics. Conclusion: Living environment during the childhood might affect atopy and asthma. Based on the identification of molds as the second most frequent allergen after mites in our study population, assessment of mold sensitization as well as in forming patients about ways to avoid them seem likely to contribute to the effective management of uncontrolled asthma.

    Full Text Available Purpose: This study is a descriptive study which aims to determine the attitude and perceptions of asthma patients about their health and their opinion regarding the success of treatment. Method: The study is carried out without any sampling. The participants are 74 patients who were admitted in a public pulmonary disease clinic between April and June 2010. A revised version of Health Belief Model scale for asthma treatment and another scale, which was developed to determine the opinion and observations of patients regarding the success of treatment, are used for data collection. In addition to descriptive statistics, regression analysis, Mann-Whitney U and Kruskal Wallis tests are used in the data analysis. Findings: The mean score of attitudes and perceptions of asthma patients, which is defined with the Health Belief Model and which can affect their responsiveness to treatment, is found out 3,37(±0,38 and the attitude and perceptions of patients are positive. The mean value for success treatment is 2,35(±0,49. Since the treatment is deemed to be more successful as it gets closer to 1 hence it can be said that the opinion of asthma patients regarding the success of treatment is positive. In the study, it is found out that the participants have a high admission rate to hospitals and that there is no significant difference for socio-demographic characteristics in the positive attitude development and in their belief in the efficiency of the treatment that they are receiving, of which both are components of health belief model concept. The findings from regression analysis indicate that the duration of the asthma sickness and the number of people living in the household not only affect the perceptions and attitudes of patients that are investigated by health belief model, but also the effectiveness of the treatment and the number of admissions to the Emergency Room in the last 6 months. Conclusion: In order to prevent long-term complications

    Interleukin (IL)-35 is a newly discovered suppressive cytokine and has been shown to alleviate inflammatory and autoimmune diseases. The purpose of this study was to investigate immunomodulatory capacity of IL-35 in patients with allergic asthma. IL-35 mRNA expression levels in peripheral blood mononuclear cells (PBMCs) were detected by quantitative real-time PCR (qPCR). The frequencies of cytotoxic T cells (Tc)1, Tc2 and Tc17 cells were measured by flow cytometry. Plasma levels of IL-35, interferon (IFN)-γ, IL-4, and IL-17 were examined by enzyme-linked immunosorbent assay (ELISA). The correlations between plasma IL-35 levels and Tc1, Tc2, and Tc17 cytokine production in allergic asthmatics (n = 25) and healthy controls (n = 12) were analyzed by Pearson's test. IL-35 protein and mRNA expression levels were down-regulated in allergic asthmatics compared with healthy controls. The frequencies of Tc2 and Tc17 cells were significantly increased in patients with asthma, and the frequency of Tc1 cells did not differ between asthmatic patients and healthy controls. Similarly, plasma levels of IL-4 and IL-17 were significantly increased in asthmatic patients, while there was no difference in IFN-γ levels between allergic asthma patients and healthy controls. More importantly, plasma IL-35 protein levels were negatively correlated with the frequency of IL-4-producing CD8+ T (Tc2) cells and with the IL-4 level in patients with allergic asthma. Our results suggest that decreased circulating IL-35 levels could contribute to the pathogenesis of allergic asthma by regulating CD8+ T cells. PMID:26547705

    The goals of treatment are prevention of fatalities, hospitalizations, and emergency department visits, along with achieving good long-term control of asthma, with reduction of symptoms, maintenance of normal activity level, prevention of exacerbations, and accelerated loss of pulmonary function (forced expiratory volume in 1 second [FEV(1)]) as well as avoiding harm from therapies. Treatment often is initiated based on severity of symptoms, physical examination findings, and, for some patients, the FEV(1) or peak expiratory flow rates. Comorbidities such as gastroesophageal reflux disease and laryngopharyngeal reflux, rhinitis or rhinosinusitis, sleep apnea, recurrent infections, smoking, and substance abuse should be addressed. Two treatment modalities are indicated only for individuals with allergic asthma: allergen-specific immunotherapy, commonly known as allergy shots, and omalizumab. Allergen immunotherapy is effective in decreasing symptoms and medication use in selected patients with mild-to-moderate allergic asthma. In addition, patients receiving allergen immunotherapy for allergic rhinitis may have a decreased risk of developing asthma. Omalizumab, a recombinant humanized monoclonal anti-IgE antibody indicated for persistent moderate-to-severe allergic asthma, has been shown to improve asthma-related quality of life, decrease clinically significant exacerbation rates, number of courses of oral corticosteroids, and reduce the severity of exacerbations. It is administered every 2-4 weeks subcutaneously, and improvement should be ascertained after 4-6 months. PMID:22794685

    Full Text Available Background. Anxiety and panic are known to be associated with bronchial asthma with variety of impact on clinical presentation, treatment outcome, comorbidities, quality of life, and functional disability in patients with asthma. This study aims to explore the pattern of panic symptoms, prevalence and severity of panic disorder (PD, quality of life, and disability in them. Methods. Sixty consecutive patients of bronchial asthma were interviewed using semistructured proforma, Panic and Agoraphobia scale, WHO Quality of life (QOL BREF scale, and WHO disability schedule II (WHODAS II. Results. Though 60% of the participants had panic symptoms, only 46.7% had diagnosable panic attacks according to DSM IV TR diagnostic criteria and 33.3% had PD. Most common symptoms were “sensations of shortness of breath or smothering,” “feeling of choking,” and “fear of dying” found in 83.3% of the participants. 73.3% of the participants had poor quality of life which was most impaired in physical and environmental domains. 55% of the participants had disability score more than a mean (18.1. Conclusion. One-third of the participants had panic disorder with significant effect on physical and environmental domains of quality of life. Patients with more severe PD and bronchial asthma had more disability.

  5. Monitoring asthma in childhood

    Full Text Available The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. However, to date there is limited evidence on how to monitor patients with asthma. Childhood asthma introduces specific challenges in terms of deciding what, when, how often, by whom and in whom different assessments of asthma should be performed. The age of the child, the fluctuating course of asthma severity, variability in clinical presentation, exacerbations, comorbidities, socioeconomic and psychosocial factors, and environmental exposures may all influence disease activity and, hence, monitoring strategies. These factors will be addressed in herein. We identified large knowledge gaps in the effects of different monitoring strategies in children with asthma. Studies into monitoring strategies are urgently needed, preferably in collaborative paediatric studies across countries and healthcare systems.

    Objective: Maximum time of the effect of antileukotriene substances - Zileuton in the treatment of patients with bronchial asthma and increased bronchial reactivity and of the salbutamol as agonist of the beta2 adrenergic receptor studied in this work. Methods: Parameters of the lung function are determined with Body plethysmography. Raw and ITGV were registered and specific resistance (SRaw) was calculated. Zileuton (Zyflo, tbl. 600 mg), producer Cornerstone Therapeutics, USA was used in the research. Results: Results of this research, in patients with bronchial asthma, indicate that antileukotriene substances–Zileuton administered in a dose of 600 mg first day (oral route of administration 4 × 1 tbl.) has not caused significant decrease of the specific resistance of the airways (SRaw) (p value 0.1 > Alpha 0.05), whereas Zileuton administered two days in a row, in a dose of 600 mg (4 × 1 tbl. a day), has caused significant decrease of the specific resistance of the airways (SRaw) (P value 0.03 < Alpha 0.05). Effect of the control with salbutamol (beta2-adrenergic receptor agonist) is efficient in the removal of the increased bronchomotor tone, causing significant decrease of the resistance (Raw), respectively of the specific resistance (SRaw), (p value 0.05 = Alpha 0.05). Conclusion: Formation of leukotrienes depends on the lypoxygenation of the arachidonic acid by 5-lypoxygenase. Zileuton is an active and powerful inhibitor of the activity of 5- lypoxygenase and as such inhibits generation of its products. Consequently, besides inhibition of cys-LTs’, zileuton also inhibits the formation of leukotriene B4 (LTB4), which is a powerful chemotactic of other eicosanoids too, which depend on the synthesis of lekotriene A4 (LTA4). This suggests that the effect of antileukotrienes (Zileuton) is not immediate after oral administration, but the powerful effect of the Zileuton seen only after two days of inhibition of cys-LTs’, and inhibition of leukotriene B4 (LTB4

The study objective was to determine the impact of medication adherence and asthma control on resource use and charges in mild asthmatic patients treated with inhaled corticosteroids (ICSs.Research design and methods: A claims database was analyzed retrospectively from October 2001–December 2007 to identify mild asthmatic patients aged 12–65 years who began ICS treatment. Demographics, drug utilization, and resource use for each patient were identified for the 365-day period before and after the index date (pre-index and post-index periods, respectively. Patients were designated as having high control high adherence (HCHA or low control low adherence (LCLA based on post-index exacerbations and the percentage of days covered; not all patients who qualified for study inclusion met adherence designation requirements. Differences between the HCHA and LCLA cohorts in resource use (eg, asthma treatment days and asthma-related treatment charges were assessed.Results: Compared with the HCHA cohort (n = 483, the LCLA cohort (n = 258 had more asthma treatment days (2.9 vs 3.9, respectively; P < 0.0001 and higher overall asthma treatment charges ($2655 vs $3345, respectively; P < 0.0001 in the post-index period. An adjusted odds ratio suggested that patients receiving mometasone furoate (MF were approximately 5 times more likely to belong to the HCHA cohort than patients receiving any other ICS (P < 0.0001.Conclusions: Better asthma control and adherence to prescribed ICSs are associated with lower asthma-related resource use and charges. Mild asthmatic patients receiving MF were more likely to be in the HCHA cohort than

    Idiopathic pulmonary hemosiderosis (IPH) is a rare disorder with unknown pathogenesis that usually presents in the first decade of life. As a result of diffuse alveolar hemorrhage, respiratory symptoms such as cough attacks, hemoptysis, dyspnea, and recurrent and refractory iron-deficiency anemia (IDA) are observed. We present an 8-year-old girl who was followed up with recurrent IDA and allergic asthma and later diagnosed with IPH. IPH was confirmed by the presence of hemosiderin-laden macrophages in bronchoalveolar lavage obtained by bronchoscopy and exclusion of the secondary causes of pulmonary hemosiderosis. Glucocorticoids and iron supplementation were started. Clinical and laboratory improvement was observed with therapy. Our case illustrates that refractory/recurrent IDA with any pulmonary symptoms may be the only presenting feature of IPH. PMID:26241728

    Full Text Available Suzanne G Bollmeier, Theresa R Prosser St Louis College of Pharmacy, St Louis, MO, USA Objective: Fluticasone furoate (FF, an inhaled corticosteroid (ICS, and vilanterol (VI, a long-acting beta2 receptor agonist (LABA, is a new combination used in an Ellipta® device. This article compares FF–VI to other ICS–LABA combinations available, particularly emphasizing product selection from the patient perspective. Data sources: A PubMED and EMBASE search completed in October 2015 identified trials using the MeSH terms “fluticasone”, “vilanterol”, and “asthma”. Additional information was gathered from references cited in the identified publications, the manufacturer, package insert, and ClinicalTrials.gov registry. Study selection/data extraction: Preference was given to randomized controlled clinical trials. Animal trials, trials for COPD, and non-English sources were excluded. Data synthesis: Seven efficacy trials of FF–VI in asthma were identified. Only one (24 weeks trial compared FF–VI to another ICS–LABA combination (fluticasone propionate–salmeterol. Primary outcomes (usually lung function and secondary outcomes (eg, quality of life and symptom scores were comparable. In three FF–VI safety trials, the type and frequency of common adverse reactions (ie, thrush and dysphonia were similar to those in clinical trials. Over 90% of subjects rated the Ellipta® device as “easy to use” and demonstrated correct device technique initially and at 4 weeks. Conclusion: Individuals may have drug- and device-specific preferences that should be incorporated into therapeutic decision making. Limited data indicate that clinical and patient-oriented efficacy/safety outcomes of FF–VI are likely comparable to other available combinations for adults with asthma. Patient-friendly features include once-daily dosing, flexibility of dose timing, and design/ease of the use of the device. Additional larger and long-term comparative

    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.

Material and methods. 10 healthy controls, 15 patients with allergic (atopic and 15 persons with non-allergic BA were examined. A transcription factor GATA-3 expressed in peripheral lymphocytes was analyzed by Western blot after the lymphocytes were lysed. Preparation of cell lysates, and Western blotting were performed by means of a standard procedure (Amersham. An antibody against GATA-3 (Abcam, UK was used. Levels of the protein were analyzed versus β-actin levels using anti-actin antibody (Sigma Aldrich, USA. Results. Expression of GATA-3 was significantly increased in lymphocytes of patients with allergic BA as compared to healthy persons and non-allergic BA patients. The level of GATA-3 negatively correlated with the degree of airflow obstruction and positively correlated with dosage of parenteral steroids administered. Conclusion. GATA-3 may play a key role in the pathophysiology of BA. One may suggest that increased expression of GATA-3 transcription factor in atopic BA underlie high levels of Th2-cytokines production in allergic disease

    This work was aimed to study clinical features of H. pylori-associated duodenal ulcer (DU) and elucidate morphological features of gastric mucosa (GM) in patients with bronchial asthma (BA). Simultaneous prospective examination of 118 patients aged 18-64 yr included clinical and endoscopic study of the gastroduodenal region with the assessment of gastroenterological symptoms and morphological analysis of GM and duodenal biopsies by histological, histochemical, and morphometric methods. It was shown that GM inflammation in patients with DU and BA is associated not only with H. pylori infection but also with the phase of BA. Structural changes of GM in the patients with DU and BA, unlike those with DU without BA, were apparent not only in the antrum but also in the fundus. Growing density of eosinophil, neutrophil and mast cell infiltration of fundal and antral GM as well as increased total number of cells in the antrum reflects active immune-mediated inflammation in GM lamina propria. It is concluded that negative effect of uncontrolled BA on the clinical course of DU is not restricted to the association of DU exacerbation with the absence of BA control; it is also responsible for enhanced activity of gastritis. One of the possible factors determining combination of H. pylori-associated duodenal ulcer with BA is chronic hyperergic inflammation and marked structural changes in GM. PMID:25269182

    Full Text Available Context: Asthma is a chronic airway disorder which is associated to the inflammatory cells. Inflammatory and immune cells generate more reactive oxygen species in patients suffering from asthma which leads to tissue injury. Aims: To investigate the role of oxidant-antioxidant imbalance in disease progression of asthmatic patients. Settings and Design: In this study, 130 asthmatic patients and 70 healthy controls were documented. Methods: For this malondialdehyde level, total protein carbonyls, sulfhydryls, activity of superoxide dismutase (SOD, catalase, glutathione peroxidase (GPx, total blood glutathione, and total antioxidant capacity (FRAP were measured. Statistical Analysis Used: Analysis of the data was done using unpaired student t test and one-way ANOVA analysis. P < 0.05 was considered significant. Results: The present work showed that the systemic levels of MDA (4.19 ± 0.10 nmol/ml, P < 0.001 and protein carbonyls (1.13 ± 0.02 nmol/mg, P < 0.001 were found to be remarkably higher in asthmatic patients while protein sulfhydryls (0.55 ± 0.01 mmol/l, P < 0.05 decreased as compared to controls (2.84 ± 0.12 nmol/ml, 0.79 ± 0.02 nmol/mg and 0.60 ± 0.02 mmol/l, respectively.

    A spirometric study was performed in order to evaluate the response to the administration of 200 mg of salbutamol, just before and after the daily administration of 8 mg of triamcinolone, for an average period of 2 weeks, in 21 patients with chronic obstructive pulmonary disease or asthma. Eleven patients responded with a significant increase of FVC or FEV1 or FEF25-75%, after administration of corticoid. Ten patients did not respond. In average there was a significant increase of the FVC and VEF1 (p < 0.01) and of FEF25-75% (p < 0.05) after the administration of corticoid. There was no significant difference between the responders and not responders when the age, initial FVC, FEV1 and FEF25-75% were taken in consideration. A significantly greater number of responders to corticoid responded also to the bronchodilator with an increase of FEF25-75%. There was a significant negative correlation between the intensity of the response to corticoid versus bronchodilator measured with delta FEF25-75%. The administration of corticoid did not change the response to bronchodilator. PMID:1843711

    Blunted perception of dyspnoea under resistive loading has been observed in patients with a history of near-fatal asthma (NFA). The perception of dyspnoea at rest and at the end point of various exercises was assessed in such patients. Respiratory function and exercise capacity (6-min walking distance, incremental cycloergometry and inspiratory threshold loading) were assessed in seven NFA and eight non-NFA patients. Dyspnoea (Borg scale) was measured at rest and at the end point of the various exercises. Dyspnoea at rest was significantly lower in NFA patients. Although exercise tolerance was similarly reduced in both the NFA and non-NFA groups, dyspnoea at peak cycle exercise was significantly lower in the former (2.6+/-2 versus 6.1+/-3.8 (Borg scale; mean+/-SD)), who mainly (86%) stopped because of leg discomfort. A similar trend was observed in the 6-min walking distance and inspiratory threshold loading tests. Dyspnoea at peak exercise was the best indicator of the NFA condition, with a sensitivity of 100% and specificity of 63% for a Borg scale score of < or = 6. Perception of dyspnoea is blunted in near-fatal asthma patients at both rest and the end point of various forms of exercise. Dyspnoea at peak exercise is the best indicator of the near-fatal asthma condition. PMID:15332388

    Biomarkers have been critical for studies of disease pathogenesis and the development of new therapies in severe asthma. In particular, biomarkers of type 2 inflammation have proven valuable for endotyping and targeting new biological agents. Because of these successes in understanding and marking type 2 inflammation, lack of knowledge regarding non-type 2 inflammatory mechanisms in asthma will soon be the major obstacle to the development of new treatments and management strategies in severe asthma. Biomarkers can play a role in these investigations as well by providing insight into the underlying biology in human studies of patients with severe asthma. PMID:27401625

    A 53-year-old man with a history of blood transfusion at the age of 20 was admitted to our hospital because of liver dysfunction. He had bronchial asthma when he was 18 years old, which naturally resolved within 2 years. However, his bronchial asthma recurred at the age of 45 and was treated with oral theophylline. He was diagnosed as having chronic hepatitis C based on the histological and clinical findings, and then interferon (IFN) therapy was administered. The frequency of bronchial asthma attack was gradually decreasing after IFN therapy with marked improvement of hypereosinophilia. He achieved sustained viral response (SVR) and his bronchial asthma did not worsen even after the cessation of IFN. Hepatitis C virus (HCV) infection and IFN therapy were considered in the remission of asthma in this case. HCV infection could be the cause of bronchial asthma, especially in patients with late appearance of asthma.

  3. The cost of asthma: can it be reduced?

    Science.gov (United States)

    Mellis, C M; Peat, J K; Woolcock, A J

    1993-03-01

    Asthma is a major public health problem in developed countries, where it consumes a large and increasing share of scarce health resources. Ideally, medical management should be both optimal in terms of improving the patient's quality of life, and cost-effective for society. At present, there is very little information relating to costs and economic efficiency of current asthma management. Although the true total cost of asthma is unknown, current estimates suggest it is high. The main value of recent total cost estimates is that they identify the most expensive areas of asthma costs, and ideally, formal cost-effectiveness analyses should be concentrated on these areas. Asthma is still under- or inappropriately diagnosed, and undertreated. Several national and international consensus plans for the optimal management of asthma in children and adults have been published. If these inadequacies in asthma management were corrected, using current treatment recommendations, the overall cost of asthma from both the community and patient perspective should fall. The situation requires increased use of preventative medications {sodium cromoglycate (cromolyn sodium) or inhaled corticosteroids}, more widespread use of written crisis plans, more proactive medical consultations (rather than reactive or urgent consultations), further expansion of asthma education programmes, and further education of medical practitioners about the optimum management of both long term asthma and the acute exacerbation of asthma in the patient's home, the doctor's office, the hospital emergency room and the hospital inpatient setting. The increased costs associated with these measures would be more than offset by reduced expenditure on bronchodilator drugs, less widespread use of nebulisers at home and in hospitals, reduced antibiotic usage, reduced need for expensive emergency medical care and particularly reduced utilisation of hospital resources. To ensure that resources are being directed into

    Full Text Available Abstract. Present study dealt with efficiency of melatonin implementation in a combination therapeutic schedule of bronchial asthma (BA. A group of 248 patients with atopic, or mixed clinical forms of BA being in exacerbation, or medication remission state, and 36 healthy donors were included into the study. Melatonin (Melaxen, Unifarm, USA was administered as a single daily dose of 0.003 g, at 21.00, accompanied by a standard therapy in twenty BA patients for 21 days. We determined contents and functional properties of Т- and B-lymphocytes, mononuclear phagocytes, IgE, IL-4, IFNγ levels, as well as melatonin concentrations in blood serum in the morning and evening time. When included into BA treatment protocol, melatonin proved to cause partial restoration of circadian rhythm for Tand B cell subpopulations, mononuclear phagocytes, cytokine production, due to its chronotropic and immunomodulating activity. This effect is associated with a more pronounced clinical effect, thus presuming reversibility of desynchronosis state.

    Full Text Available Asthma is a common lung disease worldwide, although its prevalence varies from country to country. Oman is ranked in the intermediate range based on results from the International Study of Asthma and Allergies in Childhood. A 2009 study revealed that the majority of asthmatic patients in Oman reported both daytime and nocturnal symptoms, while 30% of adults and 52% of children reported absences from work or school due to their symptoms. Despite these findings, there is little data available on the economic burden of asthma in Oman. The only accessible information is from a 2013 study which concluded that Oman’s highest asthma-related costs were attributable to inpatient (55% and emergency room (25% visits, while asthma medications contributed to less than 1% of the financial toll. These results indicate a low level of asthma control in Oman, placing a large economic burden on healthcare providers. Therefore, educating asthmatic patients and their families should be prioritised in order to improve the management and related costs of this disease within Oman.

    To investigate the distribution characteristics and linkage disequilibrium of T cell immunoglobulin domain and mucin domain protein 4 (TIM4) promoter polymorphisms in asthma patients of Chinese Han population, the promoter region of TIM4 was re-sequenced by PCR-sequencing,and linkage disequilibrium was analyzed by SHEsis software. Four single nucleotide polymorphisms (SNPs) in the promoter region of TIM4 were detected, including two new SNPs (at positions-1609, -153) and two reported SNPs (rs6874202, rs6882076). The frequency distribution of rs6882076 was different among different races (P<0.05). In addition, linkage disequilibrium among the SNPs of the promoter region of TIM4 was found and GGTG was the predominant haplotype.There were four SNPs in the promoter region of TIM4 in asthma patients of Chinese Han population,which were in linkage disequilibrium.

  10. Critical Aspects of the History of Occupational Asthma

    Directory of Open Access Journals (Sweden)

    Tarlo Susan M

    2006-06-01

    Full Text Available The medical history is the gateway to the diagnosis of occupational asthma. The medical history should indicate whether a patient's asthma began during a work period and whether the asthma worsens during work periods or improves on days when the patient is off work or on holidays. A suspicion of sensitizer-induced occupational asthma will increase if the patient was exposed to a recognized respiratory sensitizer in the workplace at the time of the onset of symptoms or if the patient had associated symptoms of allergic rhinitis and conjunctivitis. A history of accidental high respiratory irritant exposure shortly before the initial onset of symptoms would raise the possibility of irritant-induced occupational asthma. Although such features of the history are sensitive indicators of occupational asthma, they are not specific and should therefore be followed by further investigations to confirm the diagnosis of asthma and its relation to the workplace exposure. The earlier the diagnosis is suspected and investigated, the better the outcome is likely to be for the patient.

    2015-01-01

    According to asthma treatment guidelines the main goal of pulmonary rehabilitation is optimum asthma control. The Asthma Control Test (ACT) is a standardised five-item questionnaire for the assessment of asthma control. The study compares the pre- and post-treatment (subterraneotherapy) ACT score with other conventional respiratory parameters. The study included 21 patients with bronchial asthma who underwent a 3-week long subterraneotherapy programme in the 'Wieliczka' Salt Mine. The patients completed the ACT questionnaire before and 2 weeks after subterraneotherapy. At the same time, they underwent testing for concentration of nitric oxide in exhaled breath (FENO), peak expiratory flow (PEF) and spirometry. Subterraneotherapy influenced significantly the change of MEF75 (p = 0.03255) and improvement of ACT score (N = 21, p = 0.0016). The differences in other parameters were not statistically important, but in the case of FEV1 and VC parameters, the differences found were close to the statistical significance (0.05 < p < 0.10). The differences of results before and after subterraneotherapy were higher in the group assigned as patient with poor or moderate asthma control (ACT score < 20, N = 10) than in the group with good control of asthma (ACT score ≥ 20, N = 11). For parameters FEV1, VC, MEF75 and ACT score the improvement was significantly higher in the poor control group. The pulmonary rehabilitation programme combined with subterraneotherapy helps to control asthma especially in patients suffering from poorly or moderate controlled asthma. PMID:27024946

  20. Usefulness of antioxidant drugs in bronchial asthma

    International Nuclear Information System (INIS)

    Bronchial asthma is a clinical syndrome with possible correlation to oxidative stress, therefore the effectiveness of some antioxidant drugs has been studied in management of chronic bronchial asthma. Methods: This study was carried out in the Al- Kadhimia Teaching Hospital between December 2008 to May 2009 on 56 patients of both sexes who were randomly allocated to 7 groups, plus 10 healthy volunteers as control group. Each group was given one of the following drugs: vitamin E, vitamin C, combination of vitamin E and C, selenium, zinc, allopurinol and garlic oil, in addition to their classical treatment of asthma and their pulmonary function tests were conducted as well as measuring the levels of serum zinc, calcium, and malondialdehyde (MDA) before and after treatment. Results: All asthmatic patients were suffering from oxidative stress and this was detected by measuring the level of serum MDA which was 2-3 folds more than the control group, and all antioxidants except allopurinol showed a beneficial effect of different degrees in the pulmonary function tests accompanied with clinical improvement of patients' condition and marked decrease in the number of daily attacks. Antioxidants can compensate the oxidative stress that correlates with asthma, can reduce the symptoms of asthma, and improve pulmonary functions. (author)

The correlations between plasma IL-35 levels and Tc1, Tc2, and Tc17 cytokine production in allergic asthmatics (n = 25 and healthy controls (n = 12 were analyzed by Pearson’s test.IL-35 protein and mRNA expression levels were down-regulated in allergic asthmaticscompared with healthy controls. The frequencies of Tc2 and Tc17 cells were significantly increased in patients with asthma, and the frequency of Tc1 cells did not differ between asthmatic patients and healthy controls. Similarly, plasma levels of IL-4 and IL-17 were significantly increased in asthmatic patients, while there was no difference in IFN-γ levels between allergic asthma patients  and  healthy  controls.  More importantly,  plasma  IL-35 protein levels were negatively correlated with the frequency of IL-4-producing CD8+ T (Tc2 cells and with the IL-4 level in patients with allergic asthma.Our results suggest that decreased circulating IL-35 levels could contribute to the pathogenesis of allergic asthma by regulating CD8+ T cells.

    Our objective was to evaluate the reproducibility of Asthma Control Questionnaire 7 (ACQ-7) in asthma patients, comparing our results against those obtained with the Global Initiative for Asthma (GINA) criteria. We evaluated 52 patients. Patients completed the ACQ-7, underwent spirometry, and were clinically assessed to determine the level of asthma control according to the GINA criteria, in two visits, 15 days apart. The ACQ-7 cutoff for uncontrolled asthma was a score of 1.5. The ACQ-7 show...

    The terms 'exercise-induced asthma' (EIA) and 'exercise-induced bronchoconstriction' (EIB) are often used interchangeably to describe symptoms of asthma such as cough, wheeze, or dyspnoea provoked by vigorous physical activity. In this review, we refer to EIB as the bronchoconstrictive response and to EIA when bronchoconstriction is associated with asthma symptoms. EIB is a common occurrence for most of the asthmatic patients, but it also affects more than 10% of otherwise healthy individuals as shown by epidemiological studies. EIA and EIB have a high prevalence also in elite athletes, especially within endurance type of sports, and an athlete's asthma phenotype has been described. However, the occurrence in elite athletes shows that EIA/EIB, if correctly managed, may not impair physical activity and top sports performance. The pathogenic mechanisms of EIA/EIB classically involve both osmolar and vascular changes in the airways in addition to cooling of the airways with parasympathetic stimulation. Airways inflammation plays a fundamental role in EIA/EIB. Diagnosis and pharmacological management must be carefully performed, with particular consideration of current anti-doping regulations, when caring for athletes. Based on the demonstration that the inhaled asthma drugs do not improve performance in healthy athletes, the doping regulations are presently much less strict than previously. Some sports are at a higher asthma risk than others, probably due to a high environmental exposure while performing the sport, with swimming and chlorine exposure during swimming as one example. It is considered very important for the asthmatic child and adolescent to master EIA/EIB to be able to participate in physical activity on an equal level with their peers, and a precise early diagnosis with optimal treatment follow-up is vital in this aspect. In addition, surprising recent preliminary evidences offer new perspectives for moderate exercise as a potential therapeutic tool for

    The association between asthma and obesity is well-described, but not straightforward, and according to current guidelines asthma control is more difficult to achieve in obese patients. 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...... admissions. Obese patients, who present with symptoms suggesting a diagnosis of asthma, may have a distinct phenotype or a disease mimicking asthma, likely to have a potentially higher remission rate. And by that, our approach to this group of patients should combine pharmacologic and non...

  7. An imperfect "PAST" Lessons learned from the National Review of Asthma Deaths (NRAD) UK.

    Asthma deaths are a barometer of the quality of asthma care. The principal care for patients with severe asthma is often a joint partnership between primary and secondary services. Communication between the two services determines the effectiveness of treatment. Undertaking an audit on asthma in either primary or separately in secondary care is a relatively straightforward process. However, when the audit spans both primary and secondary care in a country as large as the United Kingdom which is further sub-divided into the separate healthcare systems of England, Wales, Scotland, and Northern Island, then the audit becomes considerably more challenging. The National Review of Asthma Deaths (NRAD) reported in May 2014 was a confidential enquiry tasked with identifying circumstances surrounding asthma deaths across the whole of the UK, in order to ascertain avoidable factors and make recommendations to improve care and reduce future asthma deaths (Why asthma still kills: the National Review of Asthma Deaths (NRAD) Confidential Enquiry report, 2014, http://www.rcplondon.ac.uk/sites/default/files/why-asthma-still-kills-full-report.pdf ). The idea for NRAD arose from a longstanding East of England confidential enquiry started in 1988 by Dr Brian Harrison and then handed onto me in 2001 until funding for the national review of asthma deaths was secured in 2010.

    2005-01-01

    @@ Asthma is a chronic inflammatory airway disease characterized by the involvement of many cells (including eosinophils, mast cells, T cells, neutrophils and airway epithelial cells) and their cellular components.1 While airway eosinophilic inflammation is considered as a characteristic of asthma, our previous reports2,3 and other recent studies4,5 have demonstrated that neutrophils may play important roles in airway inflammation, or even in airway remodeling, particularly in severe asthma. The mechanisms underlying the neutrophil accumulation in asthmatic airway remain to be elucidated. Interleukin-8 (IL-8) is a potent chemotactic factor for neutrophils, and was demonstrated to be increased in asthmatic airways.6,7 More recent studies have shown that T-cell derived IL-17 can accumulate neutrophils via a IL-8 dependent pathway.8,9 Whether IL-17/IL-8 mechanism is involved in airway inflammation in severe asthma is not clear.

  10. The distribution of dust mite allergen in the houses of patients with asthma

    International Nuclear Information System (INIS)

    Using an inhibition radioimmunoassay for the major allergen from Dermatophagoides pteronyssinus (antigen P1), we studied the distribution of this dust allergen in the houses of patients with asthma. Both bed and floor dust samples contained a wide range of antigen P1, 100 to 100,000 ng/g of fine dust, and this concentration correlated well with the number of mite bodies (r . 0.81, p less than 0.001). We were unable to detect antigen P1 in the air of undisturbed rooms. However, during domestic activity, between 1 and 30 ng were collected on a filter than sampled air for 45 min at 17 L/min. Using a cascade impactor it was shown that greater than 80% of the airborne antigen P1 was associated with particles greater than 10 mu in diameter. Some of the particles containing allergen could be identified because they formed precipitin rings when impacted onto agarose containing rabbit antimite antiserum. These particles had the physical appearance of mite feces, which are the major source of antigen P1 in mite cultures. The results suggested that natural exposure to this dust allergen allows occasional fecal particles to enter the lungs and that these particles contain very concentrated allergen

    Full Text Available Abstract Background Asthma is an increasing problem in this country and others. Although medications for the treatment of asthma abound and are improving, there are inherent risks and side effects with all of them. Intravenous magnesium has been employed in the treatment of acute asthma, but its use has not become universal, nor has it been studied for the treatment of chronic asthma. It is known to be a safe drug with minimal side effects. In this study, the author investigates the use of magnesium and other nutrients in the treatment of both acute and chronic asthma. Methods In this non-blinded outcome study, following informed consent, forty-three (43 randomly selected volunteer patients with both acute and chronic asthma were treated with IV infusions described herein. All patients were observed with spirometry 10 minutes post-infusion; two sub-groups of patients were also observed after multiple infusions over a short period of time (less than one month and a longer period of time (average 5.8 months. Pulmonary function was analyzed by spirometric testing with pre- and post-infusion spirometric measurements with the pre/post group. For longer term (Trend patients, baseline spirometry measurements were compared to spirometry measurements after patients had received multiple infusions over a period of time. Eight (8 patients were measured for both pre/post and Trend data. Results The 38 pre-infusion/post-infusion patients with acute and chronic asthma demonstrated an overall average improvement (percentage improvement in percent predicted of 45%. The 13 patients measured for improvement over time (Trend data, average duration 5.82 months, demonstrated an overall average improvement (percentage improvement in percent predicted of 57%.

    Allergic asthma is a disease characterized by persistent allergen-driven airway inflammation, remodeling and airway hyperresponsiveness (AHR). CD4+ T-cells, in particular T-helper type 2 (Th2) cells, play a critical role in orchestrating the disease process through the release of cytokines like IL-4, IL-5 and IL-13.

    This study explores the relationship between Asian dust storms (ADSs), asthma hospital admissions and average medical cost discharge. We adopt the hospitalisation data from the Taiwan National Health Insurance research database covering the period from 2000 to 2009. The autoregressive integrated moving average with exogenous variables (ARIMAX) analyses were performed to explore the relationship between ADS and asthma hospital admissions, adjusting for temperature, air pollutants and season dummy. The results show that ADS events do generate a critical influence upon the occurrences of asthma on post-ADS events from days 1 through 3, with an average of 17-20 more hospitalised admissions, and have stronger effects on preschool children, middle-aged people and the elderly. From the perspective of medical expenses, the cost of hospitalised admissions for asthma substantially rises daily, on average, by NT$634,698 to NT$787,407 during ADS event days. This study suggests that government should establish a forecast and alert system and release warnings about dust storms, so that the individuals predisposed to asthma can take precautionary measures to reduce their outdoor exposure. Consequently, personal risk and medical expenditure could be reduced significantly, especially for preschool children, middle-aged people and the elderly with asthma. PMID:25186129

Although recent surveys have reported that the majority of pediatric patients with asthma in the United States and......

    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.

  1. Supported self-management for asthma

    Directory of Open Access Journals (Sweden)

    Hilary Pinnock

    2015-06-01

    The evidence in favour of supported self-management for asthma is overwhelming. Self-management including provision of a written asthma action plan and supported by regular medical review, almost halves the risk of hospitalisation, significantly reduces emergency department attendances and unscheduled consultations, and improves markers of asthma control and quality of life. Demographic and cultural tailoring enables effective programmes to be implemented in deprived and/or ethnic communities or within schools. A crucial component of effective asthma self-management interventions is the provision of an agreed, written personalised action plan which advises on using regular medication, recognising deterioration and appropriate action to take. Monitoring can be based on symptoms or on peak flows and should specify thresholds for action including increasing inhaled steroids, commencing oral steroids, and when (and how to seek professional help. Plans should be personalised to reflect asthma severity and treatment regimes, avoidance of triggers, co-morbid rhinitis and the individual’s preferences. Implementation is a challenge. Systematic review evidence suggests that it is possible to implement asthma self-management in routine care, but that to be effective this requires a whole systems approach which considers implementation from the perspective of patient education and resources, professional skills and motivation and organisation priorities and routines.

    Asthma is a heterogeneous airway disease with various clinical phenotypes. It is crucial to clearly identify clinical phenotypes to achieve better asthma management. We used cluster analysis to classify the clinical groups of 724 asthmatic patients from the Cohort for Reality and Evolution of Adult Asthma in Korea (COREA), and in 1843 subjects from another independent Korean asthma cohort of Soonchunhyang University Asthma Genome Research Centre (SCH) (Bucheon, Republic of Korea). Hierarchical cluster analysis was performed by Ward's method, followed by κ-means cluster analysis. Cluster analysis of the COREA cohort indicated four asthma subtypes: 1) smoking asthma; 2) severe obstructive asthma; 3) early-onset atopic asthma; and 4) late-onset mild asthma. An independent cluster analysis of the SCH cohort also indicated four clusters that were similar to the COREA clusters. Our results indicate that adult Korean asthma patients can be classified into four distinct clusters. PMID:23060627

There are no generic inhaled corticosteroids (ICS, which are a mainstay of asthma therapy, and patients pay the full price for these drugs under generic-only policies. We examined changes in ICS use following the introduction of generic-only coverage in a Medicare Advantage population from 2003–2004. Methods Subjects were age 65+, with asthma, prior ICS use, and no chronic obstructive pulmonary disorder (n = 1,802. In 2004, 74.0% switched from having a $30 brand-copayment plan to a generic-only coverage plan (restricted coverage; 26% had $15–25 brand copayments in 2003–2004 (unrestricted coverage. Using linear difference-in-difference models, we examined annual changes in ICS use (measured by days-of-supply dispensed. There was a lower-cost ICS available within the study setting and we also examined changes in drug choice (higher- vs. lower-cost ICS. In multivariable models we adjusted for socio-demographic, clinical, and asthma characteristics. Results In 2003 subjects had an average of 188 days of ICS supply. Restricted compared with unrestricted coverage was associated with reductions in ICS use from 2003–2004 (-15.5 days-of-supply, 95% confidence interval (CI: -25.0 to -6.0. Among patients using higher-cost ICS drugs in 2003 (n = 662, more restricted versus unrestricted coverage subjects switched to the lower-cost ICS in 2004 (39.8% vs. 10.3%.

  13. Modern Technologies of Bronchial Asthma Control in Children (Review

    Directory of Open Access Journals (Sweden)

    Т.I. Eliseeva

    2015-06-01

    Full Text Available Bronchial asthma ranks among the most common allergic diseases in children. It is chronic inflammatory disease of the respiratory tract, in which many cells of innate and adaptive immune system participate together with epithelial cells causing the main clinical syndromes typical for the disease. Currently, bronchial asthma therapy aims at obtaining the control over the symptoms and course of asthma by providing an anti-inflammatory baseline therapy using different groups of pharmaceuticals: inhaled glucocorticosteroids, leukotriene receptor antagonists, cromones, beta-2-agonists and long-acting theophyllines, systemic glucocorticosteroids and anti-IgE-therapy. However, despite a wide range of approaches to anti-inflammatory baseline therapy, it is still a problem to obtain the disease control in most patients indicating the necessity for searching new therapeutic approaches. In this regard, to optimize pathogenetic therapy of bronchial asthma, the work is being currently carried out to improve the existing anti-inflammatory drugs and their combinations. Moreover, there is a search for crucially new approaches to asthma treatment with due consideration of the disease phenotypes and endotypes including development and practical application of pharmaceutical drugs with anti-cytokine and anti-mediator effects. Probably, as far as the knowledge of molecular characteristics of asthma endotypes is being refined, and there being introduced the biomarkers enabling to diagnose asthma phenotypes and endotypes and monitor asthma control, there will be implemented an individual approach in individual therapy administration.

    Full Text Available Ricardo A Tan1, Jonathan Corren21California Allergy and Asthma Medical Group, Los Angeles, CA; 2Allergy Research Foundation, Los Angeles, CA, USAAbstract: Inhaled corticosteroids (ICS have proven to be the most effective and essential therapy for the treatment of bronchial asthma. The 2007 National Asthma Education and Prevention Program guidelines recommend ICS as preferred therapy for patients with mild to severe persistent asthma. Mometasone furoate (MF is a relatively new ICS agent with high affinity for the glucocorticoid receptor. It is approved in the US for maintenance treatment of asthma for patients 4 years of age and older. It has been shown to be well tolerated with no significant adverse side effects observed in clinical trials and post-marketing surveillance. The efficacy of mometasone furoate has been established in large, well-designed studies. In patients with persistent asthma previously treated either with short-acting beta-agonists alone or twice-daily maintenance therapy with ICS, once-daily MF has been shown to be superior to placebo in improving lung function, symptom control, and quality of life; and has shown comparable efficacy compared with budesonide, beclomethasone, and fluticasone. Twice-daily dosing with MF has been demonstrated to successfully allow for reduction or elimination of oral corticosteroids in severe asthmatics.Keywords: inhaled steroids, mometasone furoate, once-daily dosing, asthma, stepwise approach

    Full Text Available Abstract Background To compare the efficacy and safety of budesonide/formoterol (Symbicort® with formoterol (Oxis® in the treatment of patients with acute asthma who showed evidence of refractoriness to short-acting β2-agonist therapy. Methods In a 3 hour, randomized, double-blind study, a total of 115 patients with acute asthma (mean FEV1 40% of predicted normal and a refractory response to salbutamol (mean reversibility 2% of predicted normal after inhalation of 400 μg, were randomized to receive either budesonide/formoterol (320/9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 1280/36 μg] or formoterol (9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 36 μg]. The primary efficacy variable was the average FEV1 from the first intake of study medication to the measurement at 90 minutes. Secondary endpoints included changes in FEV1 at other timepoints and change in respiratory rate at 180 minutes. Treatment success, treatment failure and patient assessment of the effectiveness of the study medication were also measured. Results FEV1 increased after administration of the study medication in both treatment groups. No statistically significant difference between the treatment groups was apparent for the primary outcome variable, or for any of the other efficacy endpoints. There were no statistically significant between-group differences for treatment success, treatment failure or patient assessment of medication effectiveness. Both treatments were well tolerated. Conclusion Budesonide/formoterol and formoterol provided similarly rapid relief of acute bronchoconstriction in patients with asthma who showed evidence of refractoriness to a short-acting β2-agonist.

A large body of evidence has demonstrated the importance of small airways as a pharmacological target in these clinical conditions. Despite a deeper understanding of the pathophysiological mechanisms, the epidemiological observations show that a significant proportion of asthmatic and COPD patients have a suboptimal (or lack of control of their diseases. Different factors could influence the effectiveness of inhaled treatment in chronic respiratory diseases: patient-related (eg, aging; disease-related (eg, comorbid conditions; and drug-related/formulation-related factors. The presence of multiple illnesses is common in the elderly patient as a result of two processes: the association between age and incidence of degenerative diseases; and the development over time of complications of the existing diseases. In addition, specific comorbidities may contribute to impair the ability to use inhalers, such as devices for efficient drug delivery in the respiratory system. The inability to reach and treat the peripheral airways may contribute to the lack of efficacy of inhaled treatments. The recent development of inhaled extrafine formulations allows a more uniform distribution of the inhaled treatment throughout the respiratory tree to include the peripheral airways. The beclomethasone/formoterol extrafine formulation is available for the treatment of asthma and COPD. Different biomarkers of peripheral airways are improved by beclomethasone

    Combination products often have useful clinical benefits in asthma. The scientific rationale for combination therapy includes the fact that different agents have complimentary modes of action. Long-acting beta(2)-agonists have effects on airway smooth muscle, and inhaled corticosteroids have potent topical antiinflammatory effect. This combination has been shown to effectively reduce exacerbations and improve symptoms. Substantial clinical trial data provide a rationale for dual-control therapy supported by basic scientific data. Another combined therapy is inhaled steroids plus leukotriene-receptor antagonists, which provides the patient with two effective therapies. Leukotriene-receptor antagonist can also be combined with antihistamines for improved asthma control. Older therapies including theophylline and controlled release albuterol have been effectively added to inhaled corticosteroids, enabling a reduction in the dose of the inhaled steroids. Many other combination therapies are presently being tested. PMID:11224725

Asthmatic patients demonstrate increased production of cysteinyl leukotrienes during naturally occurring asthma and acute asthma attacks as well as after allergen and exercise challenge. The leukotriene receptor antagonists montelukast, zafirlukast...... provide benefits that are additive with corticosteroid therapy. This supposition is supported by clinical observations that treatment with leukotriene receptor antagonists significantly improve asthma control when added to inhaled corticosteroid therapy. Moreover, the bronchodilator properties of the......Cysteinyl leukotrienes, synthesized de novo from cell membrane phospholipids, are proinflammatory mediators that play an important role in the pathophysiology of asthma.

    Full Text Available BACKGROUND: The prevalence of IgE mediated food allergies has increased over the last two decades. Food allergy has been reported to be fatal in highly sensitive individuals. Legumes are important food allergens but their prevalence may vary among different populations. The present study identifies sensitization to common legumes among Indian population, characterizes allergens of kidney bean and establishes its cross reactivity with other legumes. METHODOLOGY: Patients (n = 355 with history of legume allergy were skin prick tested (SPT with 10 legumes. Specific IgE (sIgE and total IgE were estimated in sera by enzyme-linked immunosorbent assay. Characterization of kidney bean allergens and their cross reactivity was investigated by immunobiochemical methods. Identification of major allergens of kidney bean was carried out by mass spectrometry. PRINCIPAL FINDINGS: Kidney bean exhibited sensitization in 78 (22.0% patients followed by chickpea 65 (18.0% and peanut 53 (15%. SPT positive patients depicted significantly elevated sIgE levels against different legumes (r = 0.85, p<0.0001. Sera from 30 kidney bean sensitive individuals exhibited basophil histamine release (16-54% which significantly correlated with their SPT (r = 0.83, p<0.0001 and sIgE (r = 0.99, p<0.0001. Kidney bean showed eight major allergens of 58, 50, 45, 42, 40, 37, 34 and 18 kDa on immunoblot and required 67.3±2.51 ng of homologous protein for 50% IgE inhibition. Inhibition assays revealed extensive cross reactivity among kidney bean, peanut, black gram and pigeon pea. nLC-MS/MS analysis identified four allergens of kidney bean showing significant matches with known proteins namely lectin (phytohemagglutinin, phaseolin, alpha-amylase inhibitor precursor and group 3 late embryogenesis abundant protein. CONCLUSION/SIGNIFICANCE: Among legumes, kidney bean followed by chick pea and peanut are the major allergic triggers in asthma and rhinitis patients in India
