Kolekalsiferol sonrası endotel disfonksiyonu ve damar sertliğinin diyaliz modalitesine göre değerlendirilmesi
Acta Medica Nicomedia(2023)
Abstract
ABSTRACT Objective: The risk of developing cardiovascular disease (CVD) increases significantly in children with chronic kidney disease (CKD) especially with low serum 25- hydroxyvitamin D (25OHD) levels. Herein; we aimed to compare the effects of vitamin D deficiency and the impact of cholecalciferol treatment on endothelial functions and vascular stiffness in children with CKD receiving hemodialysis (HD), peritoneal dialysis (PD) and non- dialysis(ND). Methods: 7 HD, 7 PD and 27 ND patient groups consisting of 41 children totally with low 25OHD levels were compared among each other in regards of biochemical parameters, flow-mediated dilatation(FMD) and local arterial stiffness before and after a single dose of 300.000 units of cholecalciferol treatment. Results: There was no difference in FMD and local arterial stiffness values between HD, PD and ND patient groups before vitamin D supplementation. Significant increase in endothelium-dependent FMD was observed in all patient groups after intervention with cholecalciferol; however the improvement in endothelium-independent FMD and local arterial stiffness measurements was demonstrated in patients with PD and ND. Baseline parathormon level was higher in patients on dialysis; at the end of the study, significant decrease was detected only in patient group not receiving diaysis. Conclusions: Endothelial dysfunction and impaired vascular stiffness were determined in children with CKD with low 25OHD levels regardless of the disease severity.. Recovery with cholecalciferol therapy revealed that vitamin D deficiency should be corrected even in early stages of CKD to prevent the development of CVD
