Alterações na expressão de receptores de peptídeos formilados, citocinas e monócitos que auxiliam no colapso vascular e imunológico da sepse

Abstract

Sepsis is a serious clinical syndrome responsible for most of the deaths in the Intensive Care Units. There are a number of primary causes that may develop for a clinical picture of sepsis, making it difficult to diagnose early and find effective treatment medications. The high costs of treatments and global lethality rates demonstrate the need for a better understanding of this syndrome. This study aimed to evaluate the gene expression of Formulated Peptide Receptors (FPR) in total leukocytes, analysis of systemic markers and the profile of monocyte global proteins to ascertain the changes present in the body of the individual with sepsis syndrome. The characterization of the systemic changes responsible for the death of patients with sepsis was carried out through the simultaneous quantification of 27 biomarkers. The silencing of the gene expression of FPR1 and FPR2 in patients with sepsis and septic shock, reporting as possible immunological dysfunctions caused by the absence of these FPRs. The proteomic analysis of the monocytes of patients with septic shock allowed us to investigate the contribution of this cell in the collapse of this syndrome, its influence on vascular injury, endotoxemia, inflammation and thrombosis. This research identified for the first time, what is more important for the diagnosis, prognosis and therapeutics.
