Antineutrophil Cytoplasmic Antibodies Contribute to Airway Inflammation via Induction of Neutrophil Extracellular Traps in Children With Bronchiolitis Obliterans.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveIt was found that the levels of antineutrophil cytoplasmic antibodies (ANCA) are elevated and linked to disease severity of bronchiolitis obliterans (BO) in children. This study aims to explore the mechanism of ANCA in the process of BO.
methodsPlasma from BO patients (n = 40) and healthy controls (n = 11) was analyzed for ANCA and neutrophil extracellular traps (NETs) components. Plasma IgG from ANCA-positive BO children and normal controls were used to stimulate neutrophils, measuring reactive oxygen species (ROS) and NETs production. Small airway epithelial cells (SAECs) were exposed to NETs, assessing viability by CCK8 and cytokine release by ELISA. The IgG treated neutrophils were co-cultured with SAECs, and cytokines were measured by ELISA.
resultsThe levels of ANCA and NETs components including dsDNA, neutrophil elastase (NE) and myeloperoxidase (MPO) in the plasma of BO children were significantly higher than those of healthy controls. ANCA-positive IgG induced neutrophils produce ROS and NETs. The cell viability of SAECs was significantly reduced upon treatment with NETs in a concentration-dependent manner. The levels of IL-8, IL-17, TNF-α, and TGF-β secreted by SAECs treated with NETs were increased significantly, and the degree of increase was positively correlated with the concentration of NETs. The co-culture of neutrophils stimulated by ANCA IgG with SAECs significantly increased the expression of cytokines including IL-8, IL-17, TNF-α, and TGF-β.
conclusionsNETs induced by ANCA may exacerbate airway inflammation in children with BO.
