    ABSTRACT: Objective: To determine the prevalence of viral and atypical bacteria Mycoplasma pneumoniae infection in children experiencing asthma exacerbation and compare positive and negative subjects with regard to exacerbation severity, need for hospitalization, and treatment. Methods: One hundred sixty-nine asthmatic children aged 2-15 years old who were admitted to emergency rooms in Bogota, Colombia for acute asthma exacerbation were interviewed. Nasopharyngeal aspirates were taken for DNA and RNA extraction. M. pneumoniae and virus were detected by PCR using specific primers. Results: The prevalence of M. pneumoniae and viral infection in the study population was 12.4% and 83.7%, respectively. All subjects positive for M. pneumoniae were also positive for viral infection. Rhinovirus was the most frequently detected viral agent. No significant differences in severity of asthma exacerbations or in need for hospitalization between the virus or M. pneumoniae positive and negative groups were observed. A significantly lower percentage of M. pneumoniae positive subjects had used inhaled steroids over the six months prior to asthma exacerbation compared to M. pneumoniae negative subjects (38.1% vs. 68.2%), suggesting that inhaled corticosteroids may have a protective effect against M. pneumoniae infections. Conclusions: The M. pneumoniae and virus prevalence found in this study were similar to those described in the literature. The 100% co-infection rate observed suggests that viral infection can predispose patients to M. pneumoniae infection, and that this interaction may trigger asthmatic exacerbation. Further studies should be done to confirm the protective effect of inhaled corticosteroids on M. pneumoniae infection in patients with asthma exacerbations.

    ABSTRACT: Introduction: A well-performed spirometry, using a change in forced expiratory volume in one second (FEV1) after albuterol, is commonly used to support the likelihood of an asthma diagnosis. The current standard, accepted by the 2007 National Heart Lung and Blood Institute Asthma Expert Panel Report-3 (EPR-3) guidelines, is a 12% improvement in the FEV1 after a bronchodilator. Objective: We sought to determine whether existing studies support or refute using a 12% improvement as a significant change in FEV1 in children and adolescents. Data sources: We reviewed the literature of children and adolescents using Medline searches to discover pertinent population studies and comparative studies that included FEV1 measurements. Result: The majority of the discovered studies suggest a less stringent improvement in FEV1 in children might be applicable. Conclusion: Supported by the published literature, we suggest an alternative interpretive strategy of expressing the results of a spirometry measurement when a diagnosis of asthma in a child is being considered using a bronchodilator response.

    ABSTRACT: Objective: Recent studies have made advances into understanding the complex agriculture work exposure environment in influencing asthma in adults. The objective of this study is to review studies of occupational agricultural exposures including dust, animal, and pesticide exposures with asthma in adult populations. Data sources: PubMed databases were searched for articles pertaining to farming, agriculture, asthma, occupational asthma, airway inflammation, respiratory disease, lung disease, pesticides, and organic dust. Study selections: Studies chosen were published in or after 1999 that included adults and asthma and farming/agricultural work or agricultural exposures and airway inflammatory disease measurements. Results: The data remain inconclusive. Several retrospective studies demonstrate agricultural work to be protective against asthma in adults, especially with increased farming exposure over time. In contrast, other studies find increased risk of asthma with farming exposures, especially for the non-atopic adult. Mechanistic and genetic studies have focused on defining the wide variety and abundance of microorganisms within these complex organic dusts that trigger several pattern recognition receptor pathways to modulate the hosts' response. Conclusion: Asthma risk depends on the interplay of genetic factors, gender, atopic predisposition, type of livestock, pesticide exposure, and magnitude and duration of exposure in the adult subject. Longer exposure to occupational farming is associated with decreased asthma risk. However, studies also suggest that agricultural work and multiple types of livestock are independent risk factors for developing asthma. Prospective and longitudinal studies focusing on genetic polymorphisms, objective assessments, and environmental sampling are needed to further delineate the influence of agriculture exposure in the adult worker.

    ABSTRACT: Background: Asthma pathogenesis is a complex interaction of genetic, ethnic, environmental and social/life style risk factors. Aim: The goal of this study was to identify associations, if any, in children with asthma, between environmental risk factors (exposure to second-hand tobacco smoke (STS), pet ownership, race and a family history of asthma. Methods: After IRB approval, from June 2011 to December 2014, 823 children with asthma were enrolled in this prospective cross sectional study. At the initial visit, families completed a questionnaire with information on family history of asthma, having a pet at home and exposure to STS by parents at home. Chi square analyses were calculated, with alpha level of significance ≤0.05. Results: History of asthma in parents, siblings or grandparents was reported by 575 (69.8%) patients including father (n = 154, 17.8%) and mother (n = 235, 26.5%). Children with family history of asthma (n = 575) were significantly more likely to have a pet at home and exposure to STS (n = 347, 60.3% and n = 198, 34.4%, respectively) compared to families without a history of asthma (n = 124, 50%, p = 0.006 and n = 44, 17.7%, p < 0.001, respectively). Similarly, asthmatic children with exposure to STS (n = 241) were significantly more likely to have a pet at home and a family history of asthma (n = 153, 63.5% and n = 197, 81.7%, respectively) compared to children with no STS exposure (n = 315, 55.5%, p = 0.034 and n = 371, 65.3%, p < 0.001 respectively). Conclusions: Significantly more asthmatic children with immediate relatives with a history of asthma have a pet at home and experience STS exposure compared to children without relatives with a history of asthma, suggesting association between life style choices/environmental exposures and family history of asthma.

    ABSTRACT: Introduction: Poor self-management by families is an important factor in explaining high rates of asthma morbidity in Puerto Rico, and for this reason we previously tested a family intervention called CALMA that was found effective in improving most asthma outcomes, but not effective in increasing the use of controller medications. CALMA-plus was developed to address this issue by adding to CALMA, components of provider training and screening for asthma in clinics. Methods: Study participants were selected from claims Medicaid data in San Juan, Puerto Rico. After screening, 404 children in eight clinics were selected after forming pairs of clinics and randomizing the clinics) to CALMA-only or CALMA-plus. Results: For all three primary outcomes at 12 months, the mean differences between treatment arms were small but in the predicted direction. However, after adjusting for clinic variation, the study failed to demonstrate that the CALMA-plus intervention was more efficacious than the CALMA-only intervention for increasing controller medication use, or decreasing asthma symptoms. Both groups had lower rates of asthma symptoms and service utilization, consistent with previous results of the CALMA-only intervention. Conclusions: Compliance of providers with the intervention and training, small number of clinics available and the multiple barriers experienced by providers for medicating may have been related to the lack of difference observed between the groups. Future interventions should respond to the limitations of the present study design and provide more resources to providers that will increase provider participation in training and implementation of the intervention.

    ABSTRACT: Objective: To examine the racial disparity in the association between obesity and asthma in US children and adolescents. Methods: This study was based on a nationally representative, random-digit-dial sample of US households with children less than 18 years of age from the National Survey of Children's Health in 2011/2012 and 2007. The study sample included 88,668 children ages 10-17 with data on body mass index (BMI), parental reporting of asthma diagnosis, and potential confounders. Multiple logistic regression analysis was performed to estimate the crude and adjusted odds ratios stratified by child race/ethnicity. Results: The prevalence of overweight was 15.2% and obesity was 14.1%. Self-reported asthma diagnosis was 16.7% in our study sample. Obese children were 51% more likely to have asthma compared to normal weight children after controlling for child's sex, child age, socioeconomic status, environmental tobacco smoke (ETS), and neighborhood conditions. Our study also shows that the strength of this association varied by race/ethnicity after stratification. Being male, being non-Hispanic Black or Multi-racial, below the Federal Poverty Level, ETS and having detracting neighborhood elements were also significantly associated with higher odds of having a self-reported asthma diagnosis. Conclusion: We observed a racial difference in the association between BMI and asthma in US children. Our findings have significant public health implications and may help public health practitioners to target children and adolescents at higher risk of prevention and intervention efforts.

    ABSTRACT: Objectives: Urinary incontinence (UI) has been associated with chronic respiratory symptoms, and it affects quality of life. This study evaluated the quality of life of asthmatic patients from the Assistance Program for Asthmatic Patients (PAPA) with and without UI. Methods: This is an analytical descriptive cross-sectional study using a sample of 358 women with asthma. Data were collected via the International Consultation Incontinence Questionnaire-Simplified Form (ICIQ-SF), Quality of Life in Asthma Questionnaire (QLAQ-ASTHMA) and Short Form 36 Health Survey (SF-36). Results: We found a general prevalence of UI of 55.3%. Overall quality of life scores in the SF-36 and QLAQ-ASTHMA were not related to the presence of UI. However, the amount of urine lost was significantly correlated with the subdomains physical aspects, general health, social functioning and mental health of the SF-36 and with socioeconomic and psychosocial domains of the QLAQ-ASTHMA. Conclusions: Urinary incontinence may affect a large proportion of older women with asthma. This study demonstrates the importance of routinely evaluating the occurrence of UI in order to improve the quality of life of asthmatic patients.

    ABSTRACT: Objective: To evaluate the effects of overweight/obese versus normal weight on symptoms, activity limitation and health care utilization among a group of urban children with persistent asthma. Methods: Data were obtained from the School Based Asthma Therapy trial. We enrolled 530 children ages 3-10 with persistent asthma from 2006 to 2009 (response rate: 74%). We conducted in-home interviews to assess symptoms and health care utilization. We measured height and weight in school nurse offices to determine BMI percentile, and compared normal weight children to overweight/obese (BMI >85th percentile) children. Bivariate and multivariate analyses were used. Results: We collected BMI data from 472 children (89%); 49% were overweight/obese. When controlling for child race, child ethnicity, intervention group, caregiver age and screen time, overweight/obese children had more days with asthma symptoms (4.25 versus 3.42/2 weeks, p = 0.035) and more activity limitation (3.43 versus 2.55/2 weeks, p = 0.013) compared to normal weight children. Overweight/obese children were more likely to have had an ED visit or hospitalization for any reason (47% versus 36%, OR 1.5, 95% CI 1.01, 2.19), and there was a trend for overweight/obese children to have more acute asthma visits in the past year (1.68 versus 1.31, p = 0.090). Overweight/obese children were not more likely to be taking a daily preventive inhaled corticosteroid (OR 1.0, 95% CI 0.68, 1.56). Conclusions: Overweight/obese children with persistent asthma experience more asthma symptoms, activity limitation and health care utilization compared to normal weight children, with no increased use of inhaled corticosteroids. Further efforts are needed to improve the health of these children.

    ABSTRACT: Objective: The purpose of this article is to synthesize the current literature on parent and child asthma illness representations and their consequent impact on parent–child asthma shared management. Data sources: This systematic review was conducted in concordance with the PRISMA statement. An electronic search of five computerized databases (PubMed, PsycINFO, CINAHL, Cochrane, and EMBASE) was conducted using the following key words: asthma, illness representation, and child. Due to the limited number of articles identified, the search was broadened to include illness perceptions as well. Study Selections: Studies were included if they were specific to asthma and included parent and/ or child asthma illness representations or perception, were published after 2000, and available in English. Fifteen articles were selected for inclusion. All of the articles are descriptive studies that used cross-sectional designs. Seven of the studies used parent and child participants, eight used parents only, and none used only child participants. Results: None of the selected studies describe child asthma illness representations, and only three describe parental asthma illness representations. Domains of illness representations, including symptoms, timeline, consequences, cause, and controllability were described in the remaining articles. Symptoms and controllability appear to have the most influence on parental asthma management practices. Parents prefer symptomatic or intermittent asthma management and frequently cite concerns regarding daily controller medication use. Parents also primarily rely on their own objective symptom observations rather than the child’s report of symptoms. Conclusion: Asthma illness representations are an important area of future study to better understand parent–child shared asthma management.

    ABSTRACT: Background: Asthma is a common chronic disease of childhood. Providers' adherence to asthma guidelines is still less than optimal. Objectives: To determine if an Asthma Education Program aimed at primary care practices can improve asthma care within practices and if the results vary by duration of the program. Methods: Ten practices were randomly assigned to an Early Asthma Education Intervention (EI) group or a Delayed Asthma Education Intervention (DI) group. The EI group received the intervention for 12 months and was monitored for 6 additional months. The DI group was observed without intervention for 12 months, then received the intervention for 6 months, and was monitored for 6 additional months. The program included training of asthma educators in each practice and then monitoring for improvement in medical record documentation of NAEPP asthma quality indicators by blinded random review of patient charts. Results: In the EI group, 6 month, 12 month and 18 month data revealed significant improvement in documentation of asthma severity, education, action plan, night time symptoms and symptoms with exercise compared to baseline and compared to DI group at baseline and at the 12 month interval. In the DI group, significant improvement in documentation in all of the above endpoints and also in documentation of NAEPP treatment guidelines was noted at 18 months and 24 months. In both groups, documentation levels remained relatively stable at 6 months after the intervention, with no significant differences between groups. While improved, guideline adherence was <80% for half of the indicators. Conclusion: In-office training of non-physician asthma providers improves the quality of asthma care.

    ABSTRACT: Introduction: Acute eosinophilic pneumonia (AEP) is a rapid onset and severe respiratory illness characterized by acute febrile respiratory insufficiency, eosinophilic infiltration in the lungs, and unique findings on chest imaging. Difficulty in differentiating from other respiratory distress caused by community-acquired pneumonia may result in a delayed diagnosis or treatment with empirical antibiotics. Case study: Sixteen-year-old boy who developed AEP with marked eosinophilia in bronchoalveolar lavage fluid (BALF, 36.6%), decreased diffusion capacity of the lung for carbon monoxide (62%), and unique radiological findings. Although he initially denied tobacco use, on repeated thorough clinical history questioning, he eventually admitted beginning smoking 19 days before the onset of symptoms with gradually increasing frequency. Results: His symptoms resolved quickly without use of antibiotics after cessation of tobacco and treatment with corticosteroids. Conclusion: Careful clinical history taking regarding tobacco use combined with early examination of BALF and recognition of unique radiological findings are critical for proper management of AEP.

    ABSTRACT: Objective: In epidemiological studies that aim to investigate the relationship between pet exposure and allergy/asthma, pet exposure is often ascertained by means of a questionnaire, but it is unclear which questionnaire items are used. The objective of this study was to systematically review self-reported pet exposure assessment in questionnaires used in epidemiological studies which explore the associations between pets and allergy/asthma. Methods: A systematic literature search was conducted in PubMed and papers were selected according to prespecified eligibility criteria. The pet exposure questions used were classified within a framework including direct pet contact, indirect pet contact (e.g. through carers or grandparents) and avoidance behaviour. Authors were contacted when the questions used were not reported in detail. Results: 96 full text papers were systematically reviewed. All studies assessed direct pet contact, but less than half (45%) explicitly assessed whether pets were allowed indoors. The vast majority of studies assessed both pet exposure during the first year of life and after the first year of life. The minority (13%) assessed whether pet(s) were kept at places regularly visited by the child and pet exposure in utero (15%). Even fewer studies assessed indirect contact to pets (n=8) and avoidance behaviour (n=10)., Conclusions: In epidemiological studies, the ascertainment of pet exposure through questionnaires appears to vary greatly. This variation might partly explain the inconsistent and contradictory results of the effects of pet exposure on the development of allergy and asthma.
