Testo completoSince the introduction of the astrocyte-neuron lactate shuttle (ANLS) concept by Pellerin and Magistretti in 1994, it has been proposed that lactate produced by astrocytes via glycolysis is transferred to neurons as a preferred energy substrate. More recently, the critical role of ANLS in brain activation and its associated functions has been demonstrated in vivo. Given that lactate is essential for neuronal activity, the question arises: could it also be neuroprotective in conditions characterized by cerebral energy deficits? To address this question, we used a neonatal hypoxia-ischemia (NHI) model, a leading cause of mortality and subsequent disabilities in infants. NHI results in brain lesions due to a significant reduction in oxygen (O2) and glucose supply. Currently, the only clinical treatment is moderate therapeutic hypothermia (TH), which helps limit the neurological damage caused by NHI. However, nearly half of the affected newborns do not respond favorably to this treatment. Research conducted by our team using an NHI rat model demonstrated that lactate administration has neuroprotective effects. The aim of my thesis was to determine whether lactate administration is compatible with HT following an NHI event and to compare the effects of combining these two therapies with HT alone. To achieve this goal, my thesis was structured around three main objectives:1.Development of a hypothermia protocol in an NHI rat model: This was done to identify optimal treatment conditions. Three hypothermia durations (2 h, 3 h, and 5 h) post-NHI were compared through longitudinal monitoring of brain damage using MRI (Bruker 4.7T) and various behavioral tests. Histological and immunohistochemical analysis were also conducted to provide complementary insights.2.Evaluation of the therapeutic potential of lactate combined with hypothermia: The neuroprotective effects of this combination were compared to TH alone. The optimal window for lactate administration was also established. The molecular mechanisms underlying these neuroprotective effects were investigated using Western blot analysis. Additionally, the impact of lactate on neuroinflammation was examined by evaluating its role in modulating microglial phenotypes in vitro.3.Assessment of the safety of lactate administration on neonatal blood parameters: This was conducted through a retrospective study of preterm infants who received sodium L-lactate infusions.Our findings clearly indicated that 2 hours of TH were sufficient to reduce brain lesion volumes and achieve optimal performance in behavioral tests. Moreover, lactate administration combined with TH proved to be more neuroprotective than TH alone. Finally, in the retrospective study, sodium L-lactate infusion in preterm infants did not increase lactatemia or disturb other blood parameters.In conclusion, lactate administration is neuroprotective in the context of NHI, even when combined with TH, and is safe for preterm infants, even when lactatemia is already elevated. These results suggest promising potential for clinical pediatric applications

Testo completoNeonatal hypoxic-ischemic encephalopathy (HIE) remains the leading cause of death and mortality in the term infant. A third of the survivors will develop neurological sequelae including cerebral palsy (CP), epilepsy and mental retardation. In order to improve their prognosis, these newborns undergo therapeutic hypothermia (TH), which begins no later than 6 hours after birth, maintained for a total duration of 72 hours and followed by gradual rewarming (0.5°C/h). This neuroprotective therapy has been shown to significantly decrease the extent of brain injury and the frequency of neurological sequelae. Results from animal studies revealed that ongoing hypothermia without proper anesthesia is not beneficial. Based on the observations that have been reported, piglets treated with TH with no analgesics have shown signs of instability and excessive tremors. Until now, the extent to which these results from animal experiments could be generalized to the newborn remained unknown. Thus, the purpose of my master’s project was to better understand the clinical factors that may compromise the beneficial effects of TH, in an attempt to optimize neuroprotection and improve the neurological outcome of HIE infants. Our main objective was to assess the associations between opioid doses consumed during TH, shivering recorded during TH, and the evolution of EEG discontinuity index over the course of TH, rewarming and up to 12 hours post-TH. To meet the objective, we conducted a study in 21 newborns with HIE undergoing TH, and the results have shown significant associations between high doses of opioid administered (r = - 0.493, p = 0.023), reduced shivering stress (r = 0.513, p = 0.017) and improved EEG background activity. The key findings of the study are described in more detail in Chapter 2, which presents the original manuscript submitted for publication to the “Journal of Pediatrics”, and Chapter 3, which presents a review of the literature in light of our results. In Chapter 4, we discuss future perspectives and the clinical significance of our results. At last, we hope that our study will open up new avenues for improving neuroprotection, by systematically promoting a better management of pain and cooling-induced stress.
