Paradoxical eosinophilic and cytokine responses to oral corticosteroid treatment in patients with asthma exacerbations.
Article in The journal of allergy and clinical immunology. Global, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Background: Thymic stromal lymphopoietin (TSLP) orchestrates eosinophilic inflammation, which may increase during asthma exacerbations. In contrast, microRNA-1 (miR-1) inhibits TSLP-mediated eosinophil trafficking in lung endothelium. Whether the balance of TSLP and miR-1 levels determines the response to oral corticosteroids (OCSs) during the treatment of asthma exacerbations remains unknown. Objective: Our aim was to investigate the involvement of TSLP/miR-1 axis in inflammatory response to OCS treatment for asthma exacerbations. Methods: We measured the concentrations of TSLP and other inflammatory cytokines and miR-1 expression during acute asthma exacerbations treated with standard OCSs in a real-life setting. A total of 28 consecutive patients with acute asthma exacerbations treated with OCS (prednisolone 30 mg/d) for 1 week at the emergency department were studied prospectively. Steroid responders were identified by a significant reduction in blood eosinophil counts, whereas paradoxical responders (PRs) showed no markedly decreased or even increased absolute blood eosinophil counts after OCS treatment. Differential white blood cell counts, blood cytokine levels, and miR-1 expression within and between groups were compared before and after OCS treatment. The baseline cytokine concentrations in both groups were compared with those of patients with stable asthma. Results: OCS treatment significantly reduced TSLP levels in steroid responders, whereas this effect did not occur in PRs ( Conclusions: In some asthmatic patients with acute exacerbations who do not suppress eosinophils after a course of OCS, there is a paradoxical decrease in plasma miR-1 level and increase in TSLP level versus in steroid responders, which may result in slower clinical recovery.
