The endothelial glycocalyx controls vascular permeability, cellular signaling, blood-endothelial cell adhesion, extravasation, and transmission of shear stress signals. Burn injury compromises integrity of this layer increasing vascular permeability, which is further exacerbated by large volumes of (intravenous) crystalloids. We have shown that enteral resuscitation is able to reverse burn-induced acute kidney injury (AKI), and herein, we present a follow-up examination of the integrity of the glycocalyx layer and its relationship with renal dysfunction after burn injury. ⋯ Collectively, these data demonstrate that ORS prevented increases in circulating GAGs. Furthermore, an inexpensive and simple method for detecting GAGs provides a sensitive measure of endotheliopathy after burn.

This study aimed to investigate the role of Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway in protection by peritoneal resuscitation (PR) using pyruvate-peritoneal dialysis solution (PY-PDS) against intestinal injury from hemorrhagic shock (HS) in rats. ⋯ The protection mechanism of PR with PY-PDS combined with VR was related to the inhibition of the JAK/STAT signaling pathway during HS and resuscitation. The process might include suppression of oxidative stress, reduction of neutrophil infiltration, regulation of microcirculation, and inhibition of apoptosis.
