Serum NT‐proBNP levels are associated with cognitive functions in hemodialysis patients. Issue 2 (10th January 2021) - Akkus, Gulsum
Abstract: It has been demonstrated that NT‐proBNP and macrophage inhibitor cytokine‐1 (MIC‐1/GDF‐15) are associated with cognitive functions in patients without renal disease. In the present study, we examined the association of these two molecules with cognitive functions in hemodialysis patients for the first time in the literature. A total of 94 patients were enrolled. The Mini‐Mental Test and the Montreal Cognitive Assessment Test (MoCA) were applied for the purpose of measuring the cognitive functions. The NT‐proBNP and MIC‐1/GDF‐15 levels were examined with the ELISA. The mean age of the patients was 48 ± 12; 58 (61.7%) of them were male and 21.3% were diabetic. We found that in 77% of patients have impaired cognitive functions (MoCA total score <24). The NT‐proBNP level had a significant and negative correlation with the MoCA Test Delayed Recall and Total Score. When the patients were divided into two groups according to NT‐proBNP levels (above 10.500 and below), it was observed that the Mini‐Mental Test Record Memory, MoCA Test Delayed Recall, and MoCA test total scores were significantly different from each other. In the present study, we show, for the first time in the literature, that NT‐proBNP levels are associated with cognitive functions in dialysis patients.
