T1 |
0-130 |
Sentence |
denotes |
Inhaled steroids modulate extracellular matrix composition in bronchial biopsies of COPD patients: a randomized, controlled trial. |
T2 |
131-141 |
Sentence |
denotes |
RATIONALE: |
T3 |
142-294 |
Sentence |
denotes |
Smoking and inflammation contribute to the pathogenesis of chronic obstructive pulmonary disease (COPD), which involves changes in extracellular matrix. |
T4 |
295-370 |
Sentence |
denotes |
This is thought to contribute to airway remodeling and airflow obstruction. |
T5 |
371-566 |
Sentence |
denotes |
We have previously observed that long-term treatment with inhaled corticosteroids can not only reduce bronchial inflammation, but can also attenuate lung function decline in moderate-severe COPD. |
T6 |
567-691 |
Sentence |
denotes |
We hypothesized that inhaled corticosteroids and current smoking modulate bronchial extracellular matrix components in COPD. |
T7 |
692-702 |
Sentence |
denotes |
OBJECTIVE: |
T8 |
703-958 |
Sentence |
denotes |
To compare major extracellular matrix components (elastic fibers; proteoglycans [versican, decorin]; collagens type I and III) in bronchial biopsies 1) after 30-months inhaled steroids treatment or placebo; and 2) between current and ex-smokers with COPD. |
T9 |
959-967 |
Sentence |
denotes |
METHODS: |
T10 |
968-1215 |
Sentence |
denotes |
We included 64 moderate-severe, steroid-naive COPD patients (24/40 (ex)-smokers, 62±7 years, 46 (31-54) packyears, post-bronchodilator forced expiratory volume in one second (FEV1) 62±9% predicted) at baseline in this randomized, controlled trial. |
T11 |
1216-1306 |
Sentence |
denotes |
19 and 13 patients received 30-months treatment with fluticasone or placebo, respectively. |
T12 |
1307-1451 |
Sentence |
denotes |
Bronchial biopsies collected at baseline and after 30 months were studied using (immuno)histochemistry to evaluate extracellular matrix content. |
T13 |
1452-1533 |
Sentence |
denotes |
Percentage and density of stained area were calculated by digital image analysis. |
T14 |
1534-1542 |
Sentence |
denotes |
RESULTS: |
T15 |
1543-1728 |
Sentence |
denotes |
30-Months inhaled steroids increased the percentage stained area of versican (9.6% [CI 0.9 to 18.3%]; p = 0.03) and collagen III (20.6% [CI 3.8 to 37.4%]; p = 0.02) compared to placebo. |
T16 |
1729-1873 |
Sentence |
denotes |
Increased collagen I staining density correlated with increased post-bronchodilator FEV1 after inhaled steroids treatment (Rs = 0.45, p = 0.04). |
T17 |
1874-2008 |
Sentence |
denotes |
There were no differences between smokers and ex-smokers with COPD in percentages and densities for all extracellular matrix proteins. |
T18 |
2009-2021 |
Sentence |
denotes |
CONCLUSIONS: |
T19 |
2022-2169 |
Sentence |
denotes |
These data show that long-term inhaled corticosteroids treatment partially changes the composition of extracellular matrix in moderate-severe COPD. |
T20 |
2170-2344 |
Sentence |
denotes |
This is associated with increased lung function, suggesting that long-term inhaled steroids modulate airway remodeling thereby potentially preventing airway collapse in COPD. |
T21 |
2345-2423 |
Sentence |
denotes |
Smoking status is not associated with bronchial extracellular matrix proteins. |
T22 |
2424-2443 |
Sentence |
denotes |
