Host-Pathogen Crosstalk in Pediatric Peritoneal Dialysis-Associated Peritonitis: Molecular Mechanisms Driving Peritoneal Membrane Remodeling.
Review in International journal of molecular sciences, 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
Peritoneal dialysis (PD)-associated peritonitis in children represents a complex interplay between microbial virulence, host immune activation and progressive peritoneal membrane remodeling. It should not be viewed solely as an acute infectious episode, but as a process unfolding within a chronically conditioned immune environment shaped by prolonged exposure to glucose-based dialysis solutions, oxidative stress and persistent biofilm formation on the Tenckhoff catheter. Mesothelial cells act as immunologically active sentinel cells, recognizing pathogen-associated molecular patterns through Toll-like receptors and related innate pathways. Subsequent activation of nuclear factor kappa B, inflammasome signaling and neutrophil extracellular trap formation further amplifies local inflammatory responses. Repeated inflammatory stimulation promotes mesothelial-mesenchymal transition, angiogenesis and extracellular matrix deposition driven by transforming growth factor beta 1 and interconnected profibrotic networks. In pediatric patients, prolonged PD vintage during critical stages of growth may intensify cumulative structural injury and increase the risk of ultrafiltration failure or encapsulating peritoneal sclerosis. Emerging strategies targeting inflammation, fibrosis and biofilm persistence, together with earlier molecular risk detection, may support preservation of the peritoneal membrane. A unified host-pathogen framework may therefore deepen pathophysiological insight and facilitate more individualized therapeutic strategies in pediatric PD.
