Abstract

Inflammation in the bronchial respiratory tract and lung parenchyma underlies the pathogenesis of chronic obstructive pulmonary disease (COPD). It consists of effector cell infiltration, changes in reticular basement membrane (RBM) thickness, and the content of inflammatory mediators. The aim of this study was to assess the influence of inhaled corticosteroids (ICS) on the number of inflammatory cells and RBM thickness in bronchial biopsies, and pulmonary function in patients with moderate COPD. Twenty four patients with newly diagnosed COPD were included into the study. Pulmonary function tests and fiber optic bronchoscopy with bronchial biopsies were performed before and after 12-month treatment in two groups: ICS- group (LABA plus anticholinergics) and ICS+ group (LABA plus anticholinergics plus ICS). We found that the addition of inhaled corticosteroids to the therapeutic regimen contributed to a reduction of RBM thickness, inflammation, and lung hyperinflation. The intensity of bronchial inflammatory infiltration had little effect on lung function. In conclusion, RBM thickness, an airway wall remodeling element, does not significantly affect the degree of airflow limitation.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 November 2017.
All research outputs
#20,453,782
of 23,009,818 outputs
Outputs from Advances in experimental medicine and biology
#3,987
of 4,961 outputs
Outputs of similar age
#356,212
of 421,290 outputs
Outputs of similar age from Advances in experimental medicine and biology
#414
of 490 outputs
Altmetric has tracked 23,009,818 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,961 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 421,290 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 490 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
