Human mastadenovirus pneumonia in two immunocompetent patients.
Article in Virology journal, 2025. 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
backgroundHuman adenoviruses (hAdV) are common pathogens associated with acute respiratory tract infections. Mastadenovirus blackbeardi (hAdV-B) has been linked to severe pneumonia and disseminated disease, primarily in immunocompromised patients. The histopathological and clinical features of adenoviral pneumonia remain poorly characterized. CASE PRESENTATION: We report two cases of hAdV-B pneumonia in immunocompetent female patients with a history of smoking. Both patients are of Caucasian origin and reside in Switzerland. They presented with persistent respiratory symptoms, pulmonary infiltrates on CT scans, and necrotizing granulomatous inflammation in lung tissue. After excluding other pathogens, metagenomic whole-genome sequencing identified hAdV-B in both cases. Both patients recovered fully following wedge resection of the affected lung tissue, without the need for additional therapy.
conclusionsThese two cases demonstrated a remarkably similar clinical and histopathological profile, characterized by chronic granulomatous lung inflammation. The findings suggest a prolonged inflammatory response leading to persistent tissue damage. Our observations highlight the potential of hAdV-B to cause chronic pneumonia even in otherwise healthy individuals.
