Airways Inflammation in Nocturnal Asthma

Abstract

Nocturnal asthma is a frequent problem, but the mechanism is unclear. We investigated the possibility that airways inflammation occurred during the night. Bronchoalveolar lavage fluid was analyzed in asthmatic patients with (n = 7) and without nocturnal asthma (n = 7) at 1600 and 0400 h. The nocturnal asthma group had an increase in the total leukocyte count (24.0 +/- 7.0 to 41.1 +/- 9.9 x 10(4) cells/ml, p less than 0.05), neutrophils (1.1 +/- 0.6 to 3.7 +/- 1.5 x 10(4) cells/ml, p less than 0.05), and eosinophils (0.5 +/- 0.1 to 1.7 +/- 0.7 x 10(4) cells/ml, p less than 0.05) from 1600 to 0400 h. Cellular components for the non-nocturnal asthma group did not change. Between groups, the 1600-h cells were similar. At 0400 h the nocturnal asthma group had significantly higher total leukocyte, neutrophil, eosinophil, lymphocyte, and epithelial cell counts. For all subjects, the overnight fall in peak expiratory flow rates was correlated to the change in neutrophils (r = 0.54, p less than 0.05) and eosinophils (r = 0.77, p less than 0.05). We conclude that the nocturnal worsening of asthma has an associated cellular inflammatory response that is not seen in patients without overnight decrements in lung function. This inflammatory response together with epithelial damage may be important factors in the etiology of nocturnal asthma.

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.
