Article Synopsis
- Viral lower respiratory tract infection (vLRTI) significantly impacts global child health, prompting research into the host immune responses using proteomics for better understanding and diagnosis.
- The study analyzed 1,305 proteins from tracheal aspirate and plasma of 62 critically ill children, finding 200 differentially expressed proteins that reveal key immune responses, with a robust nine-protein TA classifier showing high diagnostic accuracy (AUC of 0.96).
- It also highlighted the limited correlation between tracheal aspirate and plasma proteins and examined how viral load and bacterial co-infections influence immune signaling pathways.
Article Synopsis
- Viral lower respiratory tract infection (vLRTI) is a major cause of pediatric hospitalization and mortality globally, yet the immune responses involved are not well understood.
- A study analyzed over 1,300 proteins in tracheal aspirate and plasma from critically ill children, identifying significant protein changes linked to vLRTI and developing a diagnostic tool with high accuracy.
- Key findings included increased interferon and T cell responses in the lower airway, distinct protein profiles in plasma, and novel protein biomarkers that could enhance diagnostic approaches for severe vLRTI.
Introduction: Sepsis-induced degradation of endothelial glycocalyx heparan sulfate (HS) contributes to the pulmonary microvascular endothelial injury characteristic of acute respiratory distress syndrome (ARDS) pathogenesis. Our objectives were to (1) examine relationships between plasma indices of HS degradation and protein biomarkers of endothelial injury and (2) identify patient subgroups characterized by distinct profiles of HS degradation in children with ARDS. Methods: We analyzed prospectively collected plasma (2018-2020) from a cohort of invasively mechanically ventilated children (aged >1 month to <18 years) with ARDS.

- The study focused on pediatric in-hospital CPR events, particularly those involving bradycardia with poor perfusion, to evaluate the effects of early epinephrine on survival outcomes in children.
- Researchers analyzed data from the ICU-RESUS trial, which involved CPR events that lasted 2 minutes or longer, examining the timing of epinephrine administration and the development of pulselessness.
- Findings indicated that early epinephrine did not significantly improve the chances of survival or favorable neurological outcomes, while a high percentage of patients experienced pulselessness within the first few minutes of CPR.
