Case Report: Tezepelumab as rescue therapy in near-fatal asthma requiring extracorporeal membrane oxygenation.
Article in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Tezepelumab, an anti-thymic stromal lymphopoietin (TSLP) monoclonal antibody, reduces exacerbations across asthma phenotypes, but its role in status asthmaticus and near-fatal exacerbations requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO) is unclear. Methods and Results: We report three patients (17, 22, 57 years) with therapy-refractory hypercapnic respiratory failure initiated on VV-ECMO who received tezepelumab 210 mg within 24 h. Tidal volume and minute ventilation increased within 24-72 h, permitting decannulation by days 12-15 and ventilator weaning by days 17-28. Two patients had elevated IgE; one had normal blood eosinophils/IgE. No immediate drug-related adverse events occurred. Follow-up demonstrated lung-function recovery; one patient required escalation of maintenance therapy for persistent symptoms. Conclusion: In this small series, adjunctive tezepelumab during VV-ECMO-supported status asthmaticus appeared safe and potentially beneficial adjunctive therapy during near-fatal asthma requiring VV-ECMO. Randomized controlled studies are needed to determine the impact of TSLP inhibition on recovery time, ventilation duration, and mortality in this setting.
