Role of Oxidative Stress as a Marker of Cardiovascular Risk in Children on Regular Hemodialysis

Introduction: Chronic kidney disease (CKD) is a major public health problem worldwide, and its main consequences include loss of renal function leading to end-stage renal disease (ESRD), increased risk of cardiovascular disease (CVD), significant increase in morbidity and mortality, and a decrease in health-related quality of life.

Aims and Objectives: The basic aim of the study is to analyze the oxidative stress and total antioxidant capacity as a biomarker of cardiovascular risk in those children who are on regular hemodialysis.

Materials and Methods: This cross sectional study was conducted at DHQ hospital, Faisalabad during July 2020 to January 2021. The data were collected from the age of less than 18 years children of both sexes. There were 50 children who was selected for this study. At the time of the study, all the patients were on regular three HD sessions per week. In HD patients, venous blood samples were drawn immediately before and after hemodialysis session. Baseline laboratory investigations were carried out for all patients and controls including complete blood count, serum urea and creatinine, arterial pH, arterial blood gases and infection screening, which included blood and urinary cultures by standard methods.

Results: The data were collected from 50 dialysis patients. The mean age of this study is 15years. We collected all the demographic data of patients. The mean value of Urea is 64.34±2.44 mg/dl). At before-dialysis session, duration of disease positively correlated with TPX (r = 0.969, P <0.001), but, negatively correlated with TAC (r = −0.469, P <0.002). At after-dialysis session, HIF-1α negatively correlated with each of TPX (r = −0.529, P <0.001) and OSI (r = −0.459, P <0.003); while, OSI positively correlated with TPX (r = 0.944, P <0.001).

Conclusion: It is concluded that HD patients, the clinical and prognostic significance of oxidative status associated with cardiovascular risk factors is very different from the general population. Although a direct causality cannot be inferred from such kind of correlative investigations.
