Evaluation of Blood Protein O-GlcNAcylation Levels in Children - CHANCE Study (Child Heart O-glcnAc Nantes)
Stimulation of O-GlcNAcylation has been shown to be beneficial in several acute pathologies and different animal models, such as haemorrhagic and septic shock, and ischaemia-reperfusion (cerebral and cardiac). It could therefore be interesting to use this approach in children in order to limit the impact of various pathologies inducing SIRS, such as extracorporeal circulation for major surgery, septic shock or various traumas. The investigators demonstrated in 2 different animal models (endotoxemia by injection of Lipopolysaccharides and caecal puncture ligation model) with 3 different pharmacological molecules (Glucosamine, ThiametG and NButGT) that stimulation of O-GlcNAcylation was beneficial in the early phase of septic shock with a marked effect on cardiac function and survival. The investigators thus demonstrated that stimulation of O-GlcNAcylation was beneficial in young rats in septic shock. However, none of this work has yet been reproduced in humans, either children or adults.
