Abstract
There are different theories about the pathophysiology of sepsis-associated encephalopathy (SAE), and the majority of our knowledge was derived from critically ill patients. 7In less severe sepsis, it is probable that neuroinflammation can be a major aspect of SAE development. We hypothesized that in non-severe septic patients, blood biomarkers of inflammation, endothelial activation, coagulation, and brain function would be different when compared to patients with and without brain dysfunction. A total of 30 patients presenting with community-acquired pneumonia (CAP)-induced sepsis were included of which 10 (33 %) developed SAE. Eight medical patients admitted to the general ward, except due to sepsis or infection, which developed delirium were included as delirium, non-sepsis group. From all measured biomarkers, only brain-derived neurotrophic factor (BDNF), regulated upon activation normal T cell expressed, and presumably secreted (RANTES), and interleukin (IL)-10 where significantly different when compared to SAE and sepsis groups. In addition, SAE patients presented higher levels of BDNF, vascular cellular adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), platelet-derived growth factor (PDGF)-AB/BB ...Continue Reading
