The severity of asthma can be graded from mild intermittent to severe persistent. Airway inflammation is a feature of persistent asthma. We compared several markers of inflammation in mucosal biopsies and bronchoalveolar lavage fluid (BAL fluid) from 12 healthy control subjects, 24 patients with intermittent asthma, and 18 patients with mild-to-moderate persistent asthma. Epithelial shedding, eosinophil (EG2-positive cells), and activated T-cell (UCHL1) counts in biopsies, and ECP levels in BAL…

Airway inflammation is present during clinical remission of atopic asthma.
Symptoms of atopic asthma often disappear at puberty. However, asthmatic subjects in clinical remission will frequently have a relapse later in life. The aim of this study was to investigate whether…

TLDR
By extending the delivery of anti-inflammatory medication to the distal lung, the new HFA-based corticosteroids have the potential to treat asthma more effectively and at reduced steroid doses.

TLDR
It is demonstrated that neutrophil‐mediated inflammation is greater in patients with more severe asthma than in those with intermittent asthma.
Airway inflammation in patients with symptoms suggesting asthma but with normal lung function.
TLDR
Using lung function measurements and induced sputum analyses, a group of patients with symptoms suggestive of asthma and signs of eosinophilic airway inflammation but without enough airflow variability to be diagnosed as asthmatics were detected and seemed to respond favourably to inhaled beclomethasone dipropionate treatment.
Is there a difference between chronic airway inflammation in chronic severe asthma and chronic obstructive pulmonary disease?
TLDR
Differences in chronic airway inflammation support the consensus that asthma and chronic obstructive pulmonary disease are different diseases along all their stages of severity.

Airway structural alterations selectively associated with severe asthma.
TLDR
It is concluded that fibroblast accumulation and ASM hypertrophy in proximal airways are selective determinants of severe persistent asthma.
Smoking and airway inflammation in patients with mild asthma.
TLDR
In addition to the eosinophilic airway inflammation observed in patients with asthma, smoking induces neutrophilicAirway inflammation; a relationship is apparent between smoking history, airwayinflammation, and lung function in smoking asthmatics.
Subjects with mild and moderate asthma respond to segmental allergen challenge with similar, reproducible, allergen-specific inflammation.
TLDR
SegmentalAllergen challenge in subjects with mild and moderate asthma produces similar allergen-specific physiologic and inflammatory responses that are reproducible 6 weeks later, and in this model of allergic asthma, acute responses toallergen do not appear to be related to disease severity.
Comparison between nasal and bronchial inflammation in asthmatic and control subjects.
TLDR
The extent of eosinophilic inflammation of reticular basement membrane thickness and of the epithelium shedding is greater in bronchial than in nasal mucosa of asthmatic patients with perennial rhinitis.

Eosinophils and mast cells in bronchoalveolar lavage in subjects with mild asthma. Relationship to bronchial hyperreactivity.
TLDR
This study supports the hypothesis that bronchial hyperresponsiveness is secondary to epithelial cell damage mediated through eosinophil-derived granule products.
Indirect evidence of bronchial inflammation assessed by titration of inflammatory mediators in BAL fluid of patients with asthma.
Eosinophilic inflammation in asthma.
TLDR
Eosinophilic inflammation of the airways is correlated with the severity of asthma and these cells are likely to play a part in the epithelial damage seen in this disease.
Cellular events in the bronchi in mild asthma and after bronchial provocation.
TLDR
It is concluded that allergic asthma is accompanied by extensive inflammatory changes in the airways, even in mild clinical and subclinical disease.
Airway responsiveness to bradykinin is related to eosinophilic inflammation in asthma.
TLDR
In asthmatic patients, airway responsiveness to bradykinin but not to methacholine is related to the magnitude of eosinophilic inflammation in the airway mucosa.
Morphological integrity of the bronchial epithelium in mild asthma.
TLDR
Findings indicate that airway hyperresponsiveness may be present when there is no apparent change in the structure of the bronchial epithelium, as well as when there are no differences between the asthmatic and healthy groups.
Identification of activated T lymphocytes and eosinophils in bronchial biopsies in stable atopic asthma.
TLDR
Examination of mucosal biopsies obtained from both central and subsegmental bronchi showed that the highest number of CD45-, DC3-, DC4-, and CD8-positive cells were found in the group with asthma, and there was a significant increase in the number of interleukin-2 receptor (CD25)-positive cells.

TLDR
The light and electron microscopic structure of lobar bronchial biopsies taken at fiberoptic bronchoscopy from 11 atopic asthmatics, four of which were symptomatic and seven of whom were asymptomatic, was studied to study the structural changes in mild asthma.
Elevated bronchoalveolar lavage fluid histamine levels in allergic asthmatics are associated with increased airway obstruction.
TLDR
Asthmatics and patients with allergic rhinitis had significantly higher BAL fluid histamine than did normal subjects and levels of tryptase and histamine in BAL were not correlated with FEV1 percent predicted in the asthmatic group.
