Non-episodic angioedema with eosinophilia as a differential diagnosis of eosinophilia in young females.
Article in The World Allergy Organization journal, 2024. 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: Episodic angioedema with eosinophilia, also known as Gleich's syndrome, is a differential diagnosis in patients with recurrent angioedema with higher blood eosinophils. Meanwhile, less has been elucidated regarding non-episodic angioedema with eosinophilia (NEAE). This study aimed to examine the prevalence, clinical characteristics, and disease course of NEAE. Methods: By reviewing the electronic medical records, we identified patients with NEAE among those referred to allergy clinics due to eosinophilia from January 2021 to December 2023 at Asan Medical Center. Results: Among 687 patients with eosinophilia, 58 (8.4%) were diagnosed with and treated for NEAE. All patients were females, with a mean age of 31.79 years. The mean absolute blood eosinophil count was 4468.76 cells/μL. All patients reported symmetric angioedema of the lower legs, and 37 (63.8%) had additional angioedema of the upper arms. Twenty-five (43.1%) patients reported a preceding event prior to onset of angioedema. Systemic corticosteroids (mean total dose 1745 ± 508.49 mg) were prescribed to all patients, with a treatment duration of approximately 40 days to achieve resolution. Following the resolution of angioedema, 6 patients experienced persistent arthralgia, 1 developed chronic spontaneous urticaria, and 1 developed hypereosinophilic syndrome. Conclusions: NEAE is an essential differential diagnosis in young female patients with eosinophilia, particularly those presenting with symmetric peripheral angioedema.
