Association between serum magnesium levels and cognitive function in patients undergoing hemodialysis.
Background: The relationship between chronic kidney disease-mineral and bone disorder (CKD-MBD) and cognitive function remains largely unknown. This cross-sectional study aimed to explore the association between CKD-MBD and cognitive function in patients on hemodialysis.
Methods: Hemodialysis patients aged ≥ 65 years without diagnosed dementia were included. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). CKD-MBD markers, serum magnesium, intact parathyroid hormone (PTH), 25-hydroxyvitamin D (25-OHD), fibroblast growth factor (FGF)-23, and soluble α-klotho were measured.
Results: Overall, 390 patients with a median age of 74 (interquartile range, 70-80) years, mean serum magnesium level of 2.4 ± 0.3 mg/dL, and median MoCA and MMSE scores of 25 (22-26) and 28 (26-29), respectively, were analyzed. MoCA and MMSE scores were significantly higher (preserved cognitive function) in the high-magnesium group than in the low-magnesium group according to the unadjusted linear regression analysis (β coefficient [95% confidence interval (CI)] 1.05 [0.19, 1.92], P = 0.017 for MoCA; 1.2 [0.46, 1.94], P = 0.002 for MMSE) and adjusted multivariate analysis with risk factors for dementia (β coefficient [95% CI] 1.12 [0.22, 2.02], P = 0.015 for MoCA; 0.92 [0.19, 1.65], P = 0.014 for MMSE).
Conclusions: Higher serum magnesium levels might be associated with preserved cognitive function in hemodialysis patients. Conversely, significant associations were not observed between cognitive function and intact PTH, 25-OHD, FGF-23, or soluble α-klotho levels.
期刊介绍：
Clinical and Experimental Nephrology is a peer-reviewed monthly journal, officially published by the Japanese Society of Nephrology (JSN) to provide an international forum for the discussion of research and issues relating to the study of nephrology. Out of respect for the founders of the JSN, the title of this journal uses the term “nephrology,” a word created and brought into use with the establishment of the JSN (Japanese Journal of Nephrology, Vol. 2, No. 1, 1960). The journal publishes articles on all aspects of nephrology, including basic, experimental, and clinical research, so as to share the latest research findings and ideas not only with members of the JSN, but with all researchers who wish to contribute to a better understanding of recent advances in nephrology. The journal is unique in that it introduces to an international readership original reports from Japan and also the clinical standards discussed and agreed by JSN.
