Persistent pneumococcal colonisation in antiretroviral-treated HIV infection is associated with nasal inflammation.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Despite systemic viral suppression, people living with HIV (PLHIV) on antiretroviral therapy (ART) remain highly susceptible to pneumococcal colonisation and disease. Here, we show that long-term ART does not restore nasal mucosal immunity. Using flow cytometry, single-cell transcriptomics, and neutrophil functional assays, we identify a persistent mucosal immune signature in PLHIV-ART > 1 yr marked by epithelial-driven neutrophilic inflammation, T cell exhaustion, and cellular senescence. Neutrophils exhibit mitochondrial stress, senescence-associated secretory phenotype (SASP) gene expression, and impaired oxidative burst, particularly in individuals with pneumococcal carriage. Epithelial cells express elevated neutrophil-recruiting ligand genes, while nasal T cells display pro-apoptotic and exhaustion gene profiles. Neutrophilic inflammation is strongly associated with pneumococcal carriage density, implicating a feedforward loop between inflammation and microbial persistence. Our findings reveal tissue-specific immune dysregulation despite ART and suggest that targeting epithelial-immune signalling or neutrophil senescence may offer novel therapeutic avenues to reduce respiratory pathogen burden in PLHIV.
