METABOLOMIC AND PROTEOMIC CHANGES IN TRAUMA-INDUCED HYPOCALCEMIA

Area of Science:

• Biochemistry
• Trauma Medicine
• Systems Biology

Background:

• Trauma-induced hypocalcemia is a frequent complication with poor outcomes.
• The underlying biochemical mechanisms are not fully understood.
• Identifying these mechanisms is crucial for improving patient management.

Purpose of the Study:

• To investigate metabolomic and proteomic differences between normocalcemic and hypocalcemic trauma patients.
• To identify biochemical pathways associated with trauma-induced hypocalcemia.
• To elucidate the distinct pathology in hypocalcemic trauma patients.

Main Methods:

• Plasma samples from trauma patients were analyzed for metabolomic and proteomic profiles.
• Statistical analyses adjusted for injury severity and base excess.
• Pathway and network analyses were performed using OmicsNet and Gene Ontology.

Main Results:

• Distinct metabolomic and proteomic signatures were observed between normocalcemic and hypocalcemic patients.
• Hypocalcemic patients showed signs of mitochondrial dysfunction, inflammation, and coagulation pathway abnormalities.
• Evidence of proteolytic imbalance and increased tissue destruction was found in hypocalcemic patients.

Conclusions:

• Trauma-induced hypocalcemia is associated with early, distinct metabolic and proteomic changes.
• These changes are independent of injury severity, shock, and transfusion.
• The findings suggest a unique pathology in hypocalcemic trauma patients, highlighting potential therapeutic targets.
