Abstract :Purpose: In this study, the relationship between postoperative cognitive functions and serum fractalkine, Glial Fibrillar Acidic Protein insert ignore into journalissuearticles values(GFAP); and Cluster of differentiation 163 insert ignore into journalissuearticles values(CD163); levels in diabetic and non-diabetic patients after open heart surgery was evaluated. Methods and Materials: This research was planned prospectively as observational clinical study. Cognitive functions, fractalkine, GFAP and CD163 levels were evaluated with preoperative day 1 and postoperative day 7 in 44 patients. Minimental test insert ignore into journalissuearticles values(MM); was used to evaluate cognitive functions. Results: A positive correlation was found between preoperative CD163 concentrations and postoperative MM test scores in non-diabetic patients insert ignore into journalissuearticles values(r=0.536, p=0.010);. There was also a positive correlation between postoperative CD163 concentrations and postoperative MM Test scores in non-diabetics insert ignore into journalissuearticles values(r=0.461, p=0.031);. In diabetic patients, a positive correlation was found between preoperative and postoperative GFAP concentrations insert ignore into journalissuearticles values(r=0.792, p<0.001);. Conclusion: The underlying mechanisms of Postoperative cognitive dysfunction insert ignore into journalissuearticles values(POCD); are thought to be different in non-diabetic and diabetic patients. Evidence suggesting that preoperative serum CD163 levels may be a candidate for biomarkers directly related to postoperative cognitive performance in non-diabetic patients. In order to prevent POCD, which is associated with mortality, it is important to determine the predictors before surgery and to select the surgical method and anesthetics according to the risk assessment.
