NCT06028789

Brief Summary

The goal of the prospective observational study is to evaluate the immunological background of inflammatory response often seen after open thoracic aortic surgery. Patients scheduled for this type of procedure will undergo a series of blood testing (preoperatively, and several times postoperatively). The blood samples will be used for a wide scale of immunological tests to better evaluate potential differential markers against infection. A control group will include patients with active infective endocarditis (preoperatively). The main question is if there is a biomarker able to determine a difference between sterile systemic inflammation and infection after thoracic aortic surgery. The second question is if there is a difference in dynamics of evaluated biomarkers between sterile postoperative inflammation and active endocarditis.

Study Arms (2)

Study group

Patients undergoing elective thoracic aortic surgery.

Diagnostic Test: Blood sample testProcedure: Thoracic Aortic Surgery

Control group

Patients admitted to our institution with active infectious endocarditis.

Diagnostic Test: Blood sample test

Interventions

Blood sample testDIAGNOSTIC_TEST

The following groups of biomarkers will be examined: * standard panel of inflammation markers: CRP, PCT, IL-6, Leukocyte count, differential blood count * microbiology cultures according to the clinical status * serum biomarkers: sCD64, sTREM-1, calprotectin, pentraxin 3 * flow cytometry: HLA-DR, CD14, CD16, CD40, CD45, CD64, CD163 expression on granulocytes and monocytes * cell function assay: IL-18 and IFN-γ * hematology: ICIS, Neutrophil-to-lymphocyte ratio - examined together with conventional hematological parameters. The schedule of blood sample taking will be as follows: A. the study group: preoperatively (T-1), 1st postoperative day (T1), 3rd postoperative day (T2), 7th postoperative day (T3), 10th postoperative day (T4) B. the control group: at admission or the next day (T1), 3rd day of hospital stay (T2), 7th day of hospital stay (T3), 10th day of hospital stay (T4)

Control groupStudy group

Scheduled surgical intervention, i.e. replacement of pre-specified part of thoracic aorta by a vascular prosthesis.
