Background/Aim: Sepsis-induced acute kidney injury is a fatal, potentially reversible clinical condition. C5a receptor (C5aR) has been implied to play pivotal roles in both autophagy and sepsis-induced organ dysfunction. The aim of this study was demonstrate the effects intravenous immunoglobulin preparations on expression markers investigate possible association between C5aR tissue septic rats. Materials Methods: Sepsis induced by cecal ligation perforation (CLP) rats, which were divided...

Sepsis-induced brain dysfunction (SIBD) has been neglected until recently due to the absence of specific clinical or biological markers. There is increasing evidence that sepsis may pose substantial risks for long term cognitive impairment.To find out and inflammatory factors associated with acute SIBD serum levels cytokines, complement breakdown products neurodegeneration markers were measured by ELISA in sera 86 patients 33 healthy controls.

Intravenous (IV) immunoglobulin (Ig) treatment is known to alleviate behavioral deficits and increase survival in the experimentally induced model of sepsis. To delineate mechanisms by which IVIg prevents neuronal dysfunction, an array immunological apoptosis markers was investigated.Sepsis cecal ligation perforation (CLP) rats. The animals were divided into five groups: sham, control, CLP + saline, G (IgG) (250 mg/kg, iv), immunoglobulins enriched with M (IgGAM) iv). Blood brain samples...

Sepsis-associated encephalopathy (SAE) is a common manifestation of sepsis that may lead to cognitive decline. Our aim was investigate whether the neurofilament light chain (NFL) and soluble triggering receptor expressed on myeloid cells 2 (sTREM2) could be utilized as prognostic biomarkers in SAE.In this prospective observational study, baseline serum levels sTREM2 cerebrospinal fluid (CSF) NFL were measured by ELISA 11 SAE patients controls.
