Serum Proteomics of Experimental Malaria-Associated ARDS Reveals a Regulation of Acute-Phase Response Proteins.

Abstract

Malaria is a parasitic infectious disease considered a public health problem. Acute respiratory distress syndrome (ARDS) is a complication in malaria-infected individuals with a high mortality rate (80% to 100%) and can occur before, during, or after antimalarial drug treatment. Although inflammation and epithelial/endothelial injury pathways have been determined through these studies, specific circulating malaria-associated ARDS markers have not yet been established. We applied a quantitative mass spectrometry (MS)-based proteomic approach to identify altered molecular pathways in a mouse model of malaria-associated ARDS. Acute-phase response (APR) proteins were regulated in the ARDS group, suggesting their potential involvement in the development of the syndrome. They may serve as biomarkers when analyzed alongside other proteins that require further investigation. Additionally, the regulation of APR proteins in the ARDS group provides valuable insights into the pathophysiology of ARDS, contributing to a better understanding of the syndrome.
