Abstract

Background: Vitamin D acts as a neuroprotector and modulator in the central nervous system. Hypovitaminosis is a risk factor for cognitive dysfunction. Hypovitaminosis D and impaired cognitive function are common in patients with chronic kidney disease. Impaired cognitive function is comorbid that can increase the morbidity and mortality of patients with chronic kidney disease. This study aims to assess the relationship between serum vitamin D levels and cognitive function in patients with chronic kidney disease. Methods: This research is an observational study with a cross-sectional approach. A total of 60 research subjects participated in this study. Sociodemographic data, cognitive function, and vitamin D levels were analyzed in this study. Data analysis was performed with SPSS 25 to perform univariate and bivariate tests. Results: The impaired cognitive function was found in 56.7% of CKD patients. The median serum vitamin D level of patients with chronic kidney disease with impaired cognitive function was 30.80 ng/mL and without impaired cognitive function 42.98 ng/mL. There was a significant relationship between serum vitamin D levels and impaired cognitive function (OR=4.125, p=0.035). The cut-off point of serum vitamin D levels associated with impaired cognitive function in CKD patients was 34.8 ng/mL (sensitivity 64.7% and specificity 69.2%). Conclusion:There is a significant relationship between serum vitamin D levels and the incidence of cognitive dysfunction in patients with chronic kidney disease. The cut-off point for serum vitamin D levels associated with impaired cognitive function in chronic kidney disease is 34.8 ng/mL.

Abstract

Background: Cystatin-C acts as a neuroprotector in the central nervous system at normal levels, but high serum cystatin-C levels are associated with impaired cognitive function. Serum cystatin-C levels increase in impaired renal function, and cognitive impairment are comorbidities that can increase the morbidity and mortality of chronic kidney disease patients. This study aimed to assess the relationship between serum cystatin-C levels and cognitive function in chronic kidney disease patients. Methods: This study used a cross-sectional design with 73 samples of non-hemodialysis chronic kidney disease patients. Cognitive function was assessed using the MoCa-Ina. Serum cystatin-C levels of all samples were measured by the ELISA method. Data analysis was carried out using SPSS. Results: Impaired cognitive function in CKD patients was found to be 76.7%. The median serum cystatin-C level of CKD patients with impaired cognitive function (n=56) was 1.015 mg/dL, and without cognitive impairment (n=17) was 0.929 mg/dL. There was no significant relationship between serum cystatin-C levels (cut-off point 0.98 mg/dL) and impaired cognitive function (OR : 2.05, 95% CI : 0.680-6.175, p= 0.198). Conclusion: There is no relationship between serum cystatin-C levels and cognitive function impairment in non-hemodialysis chronic kidney disease patients.
