CASE STUDY AEBA

However, culture has very poor sensitivity and is rarely successful, while PCR testing methods are not yet standardized [ 16 , 28 ]. However, asthma prevalence is higher in post-pubertal females than post pubertal males and this fact is a large part of the explanation for the higher numbers of adult females seeking care for acute asthma [ 9 , 10 ]. Race and ethnicity also play an important role in risk of asthma exacerbation. Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma AEBA. Differential Diagnosis Possibilities for Asthma [NHLBI, ; GINA ] Infants and Children Adults Upper airway diseases Allergic rhinitis and sinusitis Obstructions involving large airways Foreign body in trachea or bronchus Vocal cord dysfunction Vascular rings or laryngeal webs Laryngotracheomalacia, tracheal stenosis, or bronchostenosis Enlarged lymph nodes or tumor Obstructions involving small airways Viral bronchiolitis or obliterative bronchiolitis Cystic fibrosis Bronchopulmonary dysplasia Other causes Congenital heart diseases Recurrent cough not due to asthma Aspiration from swallowing mechanism Dysfunction or gastroesophageal reflux.

Can equal access to care eliminate racial disparities in pediatric asthma outcomes? Background Acute exacerbations of bronchial asthma AEBA represent an important healthcare problem, accounting for a high rate of morbidity and mortality. Data concerning the pathogenetic role of M. Intrinsic host factors for this asthma subgroup are beginning to be identified, such as deficient epithelial cell production of anti-viral type I interferons. Interleukin gene expression in acute virus-induced asthma.

Thus, it is likely that there is a subgroup of asthmatics whose susceptibility to exacerbation is independent of traditional measures of asthma control. In this case, as suggested by the guidelines, the percentage of predicted value could be a guide to the severity.

Effect of race on asthma management and outcomes in a large, integrated managed care organization.

The impact of socioeconomic status on the intensity of ambulatory treatment and health outcomes after hospital discharge for adults with asthma. The first limitation of our study is that the diagnosis of AAI remains difficult because of the absence of well standardised diagnostic tests. See other stuey in PMC that cite the published article.

Taking into account the limited population size in the study, our data should be confirmed by further studies. Taking into account the limited population size in the study, our data should be confirmed by further studies.

A sub-analysis was performed among the group of patients with acute atypical infection in order to evaluate the degree of functional impairment between the two different pathogens. Newer virus detections methods such as DNA microarray-based viral detection methods show that multiple serotypes of rhinoviruses are detectable in airway secretions during respiratory infection stuey asthmatics [ 57 ].

Outcomes and Treatment Regimens TENOR Study is a 3-year, multi-center, observational study of the natural history, treatment regimens, and outcomes of severe, or difficult-to-treat asthmatics in the United States. Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma AEBA.

Two polymorphisms in the IL-4 receptor gene were associated with increased risk of severe exacerbations and lower lung function in two independent cohorts [ 83 ]. All the authors read and approved the final manuscript.

Acute Exacerbations of Asthma: Epidemiology, Biology and the Exacerbation-Prone Phenotype

Lung function in the two different groups of patients with acute atypical infection AAI and patients without AAI during the study period. Acse, one severe exacerbation per year was associated with a Patients with a radiological diagnosis of pneumonia or with impaired consciousness on admission were excluded from the study.

Interestingly, Wark et al. Asthmatic bronchial epithelial cells have a deficient innate immune response to infection with rhinovirus. Therefore, we investigated whether AAI might be associated with an acute asthma exacerbation with a particularly severe functional impairment. GMT IgG on admission The two groups were compared according to the degree of functional impairment. The global burden of asthma: The relationship between FEV1 and risk of asthma exacerbation could be because exacerbations cause or promote long term reductions in lung function or alternatively, the relationship may be a result of specific types of airway qeba or specific host factors, such as smoking, that increase the risk aebx both exacerbation and lung function decline.

In this case, as suggested by the guidelines, the percentage of predicted value could be a guide to the severity. Notably, among the approximately 4, asthmatic patients who die from acute asthma annually in the U.

Patients with a radiological diagnosis of pneumonia or with impaired consciousness on admission were excluded from the study. In addition, to a more severe asthma attack presentation, these patients also showed a slower rise of FEV1 during follow-up when compared with the group without AAI. Role of persistent infection in the control and severity of asthma: Considering that all patients eventually reached similar FEV1 values, we suggest that, in our study population, casr diversity in exacerbation intensity may have been associated with the presence of AAI.

Subjects who report aeb a respiratory tract infection as the trigger for their exacerbation have significantly higher percentages of neutrophils in their sputum [ 65 ].
