Abstract

We have applied immunohistology and in situ hybridization to bronchial biopsies of patients with chronic obstructive pulmonary disease (COPD) to examine neutrophil recruitment and to determine neutrophil chemoattractant and CXC receptor (CXCR) 1 and CXCR2 gene expression associated with acute severe exacerbations. Cells were counted in endobronchial biopsies of (1) patients with COPD intubated for exacerbations (E-COPD; n = 15), (2) those with COPD in a stable phase of their disease (S-COPD; n = 7), and (3) nonsmoker surgical control subjects intubated for a nonrespiratory surgical procedure (n = 15). In comparison with the nonrespiratory surgical procedure and S-COPD groups, neutrophilia and gene expression for epithelial-derived neutrophil attractant-78 (CXCL5), interleukin-8 (CXCL8), CXCR1, and CXCR2 were each upregulated in the E-COPD group (p < 0.01); compared with the S-COPD group, by 97-, 6-, 6-, 3-, and 7-fold, respectively (p < 0.01). In E-COPD, there was a significant positive association between the number of neutrophils and CXCR2 mRNA-positive cells (r = 0.79; p < 0.01) but not between the number of neutrophils and CXCR1 mRNA-positive cells. At the time of sampling of the mucosa, there was no association between neutrophil number and either the length of intubation or viral infection. Thus, in COPD, in addition to CXCL8 and CXCR1, CXCL5 and CXCR2 appear to play important roles in the airway neutrophilia characteristic of severe exacerbations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
