Background: Total antioxidant capacity (TAC) is one of the biomarkers to determine a person's health condition through antioxidant and oxidant activity or oxidative stress so that it can help in determining the therapy needed. However, currently, TAC levels in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD) and non-hemodialysis (non-HD) are still controversial, so further research is needed. Objective: To analyze the comparison of TAC in HD and non-HD CKD patient. Materials and Methods: This was an analytical cross-sectional study with clinical observation in CKD patient. A total of 71 CKD patients consisting of 28 CKD HD patients and 43 non-HD CKD patients were enrolled in this study. Data about the characteristics of the subjects were taken using the anamnesis method, while data about TAC were taken using the colorimetric method with COBAS C-501 0837-19 series and 0835-13 series to measure TAC levels in the serum of CKD patients. The data that has been obtained were analyzed using independent sample t-tests. Results: TAC levels were significantly higher in CKD patients undergoing HD compared to non-HD CKD patients (p <0.05). There are data on albumin as an antioxidant and MDA as an oxidative stress biomarker that affects TAC levels. Conclusion: TAC levels found to be higher in hemodialysis CKD patient compared to non-hemodialysis CKD patient.

ABSTRACT Objective To investigate the association of dietary total antioxidant capacity with anthropometric, functional, and biochemical parameters in chronic kidney disease patients on hemodialysis. Methods This is a cross-sectional study of hemodialysis patients in Western Bahia. A structured questionnaire, three 24-hour dietary recalls, anthropometric measurements and clinical and biochemical records were used for data collection. Dietary total antioxidant capacity was estimated using 24-hour dietary recalls data. A database of ferric reducing antioxidant power values for foods was used to evaluate the dietary total antioxidant capacity. Multiple linear regression was applied to assess the relationship between dietary total antioxidant capacity and anthropometric, functional, and biochemical parameters. Results A total of 97 patients were evaluated, of which 57.7% were men and 57.7% were aged between 36 and 59 years. After adjusting for gender, education level, and socioeconomic level, inverse associations were found between dietary total antioxidant capacity and body mass index (p=0.008). Handgrip strength (p=0.037) and serum albumin concentration (p=0.047) were positively associated with dietary total antioxidant capacity. Conclusion High dietary total antioxidant capacity is associated with low body mass index, high handgrip strength, and high serum albumin concentration in chronic kidney disease patients undergoing hemodialysis.

BACKGROUND: Chronic kidney disease (CKD) is often associated with an increased risk of cardiovascular disease. Cardiovascular disease in CKD can be affected by oxidative stress and inflammation. The oxidative stress can affect arterial stiffness, especially in patients with CKD, which will increase the risk of cardiovascular disease. This study aimed to explain the correlation between total antioxidant capacity (TAC) and 8-hydroxydeoxyguanosine (8-OHdG) with carotid-femoral pulse wave velocity (cf-PWV) in patients with CKD.METHODS: Forty-three CKD patients was included in this cross-sectional study. TAC was measured from serum samples by colorimetric method and 8-OHDG was measured from urine by enzyme-linked immunoassay method. cf-PWV was measured by Doppler ultrasound as a diagnostic tool for arterial stiffness.RESULTS: Significant correlations were found between age, estimated glomerular filtration rate (e-GFR), Hemoglobin A1C (HbA1C), serum creatinine, cystatin-C, and severity of CKD with urinary 8-OHdG levels. Serum creatinine, cystatin-C, severity of CKD, age, high-density lipoprotein (HDL), e-GFR, and HbA1C also had significant correlations with serum TAC levels. Other significant correlations between e-GFR, HbA1C, serum creatinine, cystatin-C, and severity of CKD with cf-PWV were also obtained. A significant negative correlation was obtained between serum TAC and cf-PWV with moderate levels of correlation coefficient (r=-0.504).CONCLUSION: There was a negative correlation between TAC and cf-PWV, but there was no significant correlation between 8-OHdG and cf-PWV in patients with CKD.KEYWORDS: chronic kidney disease, total antioxidant capacity, 8-hydroxydeoxyguanosine, carotid-femoral pulse wave velocity

Frailty, a clinical syndrome characterized by multisystem dysregulation, has been associated with high levels of oxidative stress. We investigated the association between serum total antioxidant capacity (TAC) and frailty in older men. This cross-sectional study included 581 men (age 60–90 years) enrolled in the Geelong Osteoporosis Study. Frailty comprised at least three of unintentional weight loss, exhaustion, low physical activity, slowness, and weakness. Serum TAC was measured by quantitative colorimetric determination and expressed as uric acid equivalents (mM). Relationships between TAC (in SD units) and frailty were explored using multivariable logistic regression models. Sociodemographic, anthropometric, and lifestyle variables were tested as potential confounders and effect modifiers. A sensitivity analysis excluded participants ( n = 145) in the upper quartile of TAC, who were likely to have hyperuricemia. Fifty (8.6%) men were frail. There was evidence that higher TAC levels were associated with increased likelihood of frailty ( OR 1.34, 95% confidence interval [CI; 0.99, 1.80]), and this was attenuated after adjustment for age and body mass index (BMI; OR 1.26, 95% CI [0.93,1.71]). No effect modifiers or other confounders were identified. The sensitivity analysis revealed a positive association between TAC and frailty, before and after accounting for age and BMI (adjusted OR 1.79, 95% CI [1.01, 3.17] p = .038). These results suggest a positive association between TAC levels and frailty, supporting the hypothesis that this biomarker could be useful in identifying individuals at risk of frailty. We speculate that a milieu of heightened oxidative stress in frailty may elevate the oxidative stress regulatory set point, raising antioxidant activity. This warrants further investigation.

Background: Cigarette smoke free radicals can cause cellular damage and different diseases. All the body fluids have antioxidants which protect against free radicals. Objective: The aim of this study was to evaluate salivary total antioxidant capacity and peroxidase, uric acid and malondialdehyde levels in smokers and a nonsmoking control group. Methods: Unstimulated saliva was collected from 510 males. A total of 259 subjects were current smokers and 251 were non-smokers. The levels of salivary total antioxidant capacity, uric acid, peroxidase and malondialdehyde were measured using standard procedures. Data were analyzed with t test and ANOVA. Results: The smokers were younger and dental hygiene index was higher than healthy nonsmoking controls. The mean total antioxidant capacity in smokers and nonsmokers was 0.13±0.07 and 0.21±011, respectively (P=0.001). Smokers had significantly lower peroxidase and uric acid levels than healthy controls. In addition, the mean malondialdehyde levels in the smokers and nonsmokers were 4.55 ±2.61 and 2.79 ±2.21, respectively (P=0.001). Conclusion: Cigarette smoke produces free radical and oxidative stress, causing many side effects. Salivary antioxidant levels decreased and malondialdehyde levels increased in smokers, indicating the high oxidative stress among smokers compared to nonsmokers. Cigarette smoke had deleterious effects on main salivary antioxidants levels.
