“…Standard immunosuppressive therapy usually consists of triple drug therapy using three drug classes: calcineurin inhibitors (cyclosporine or tacrolimus), antiproliferative agents and corticosteroids. Some studies reported that increased levels of malondialdehyde are a consequence of immunosuppressive therapy and that OS is induced mostly by cyclosporine A therapy ( 21 ).…”

SummaryBackgroundThe aim of the study was to evaluate parameters of oxidative and nitrosative stress as well as antioxidative parameters in a group of renal transplant recipients with stable graft function and no clinical signs of cardiovascular disease. We also aimed to determine the correlations among these parameters and to evaluate potential differences in all the biomarkers with regard to the immunosuppression protocol.MethodsWe enrolled 57 renal transplant recipients and 31 controls who were age and sex matched with the renal transplant recipients. All of the patients included in this study had post-renal transplant surgery at least 12 months earlier and were on standard immunosuppressive therapy. In this study, we determined thiobarbituric acid-reactive substances in plasma and red blood cells and advanced oxidation protein products, nitrosative stress parameters (asymmetric and symmetric dimethylarginine – ADMA and SDMA), and antioxidative parameters (total SH groups and catalase activity).ResultsThe results of our study demonstrated that the levels of oxidative and nitrosative stress were significantly increased compared to the healthy population (p<0.01 except for plasma catalase activity p<0.05). Correlation analysis showed significant positive correlations between: ADMA and SDMA (p<0.01); ADMA and nitrates (p<0.05); SDMA and nitrates (p<0.05); between OS parameters in the experimental group; AOPP and SH groups (p<0.05) and TBARS in plasma and SH groups (p<0.01), SDMA and AOPP (p< 0.05); SDMA and TBARS in plasma (p<0.05); SDMA and SH groups (p<0.01); nitrates and SH groups (p<0.05).ConclusionThere was no significant difference in oxidative and nitrosative stress parameters with respect to the immunosuppressive protocol.

“…This improvement is a consequence of reactive oxygen species (ROS) detoxification by the renal tubular function. 23,24 Studies show that renal tubular epithel arranges the redox status of ultrafiltrate in selective transport and metabolic functions. The aldehyde dehydrogenase enzyme is highly active in the renal cortex, and loss of this important renal detoxifying mechanism is primarily the cause of ROS accumulation in ESRD.…”

Objectives IL-18 mediates various inflammatory and oxidative responses including renal injury, fibrosis, and graft rejection. It has been reported that the promoter -607 and -137 polymorphisms of IL-18 influence the level of IL-18. This prospective observational study investigated the association between oxidative stress with IL-18-607 and -137 polymorphisms in renal transplant recipients. Patients and methods This study included 75 renal transplant recipients (28 female, 47 male) from living-related donors. Blood samples were collected immediately before and after transplantation at day 7 and month 1. Serum IL-18, creatinine, cystatin C, CRP, and oxidative stress markers (TOS, TAC) were measured. The Oxidative Stress Index (OSI) was calculated. Polymorphisms of the promoter region of the IL-18 gene, IL18-607A/C, and -137C/G were determined by analysis of a "real-time PCR/Melting curve". Results Serum creatinine, cystatin C, CRP, IL-18, TOS, and OSI levels significantly decreased after transplantation. Post-transplant levels of serum TAC and estimated GFR demonstrated consistent significant increases. Serum IL-18 levels were significantly higher in patients with IL-18-137 GG and IL-18-607 CC genotypes before transplantation. Conclusion Our results indicate that the IL-18-137 GG and -607 CC genotypes contribute to higher IL-18 levels; however, the influence of these polymorphisms on oxidative stress has not been observed.

“…43 At 6 months after the kidney transplant, patients receiving tacrolimus or cyclosporine have increased MDA levels. 17 Total cholesterol and triglycerides are higher in patients treated with cyclosporine than tacrolimus. Patients treated with tacrolimus or cyclosporine have similar levels of advanced oxidation protein products and total antioxidant status.…”

“…5,[13][14][15] However, there are few studies that compare the effect of calcineurin inhibitors on oxidant and an antioxidant system indices in kidney transplant recipients. [16][17][18][19][20] The purpose of this prospective study was to evaluate the effects of the calcineurin inhibitors tacrolimus and cyclosporine on cardiovascular disease risk factors, including high-sensitivity CRP (hsCRP), homocysteine, malondialdehyde (MDA, a lipid peroxidation biomarker of oxidative stress), and activity of PON and arylesterase (components of the antioxidant system), in kidney transplant recipients.…”

Objectives: Cardiovascular disease is a common cause of morbidity and mortality in patients with chronic kidney failure, before and after a kidney transplant. Oxidation of lipoproteins that contain apolipoprotein B may contribute to the initiation of atherosclerosis. Paraoxonase may prevent cardiovascular disease. We compared the effects of different calcineurin inhibitors on risk factors for cardiovascular disease in kidney transplant recipients. Materials and Methods: In 16 kidney transplant recipients, treatment included tacrolimus in 8 patients and cyclosporine in 8 patients. Hemoglobin, glucose, renal function, lipid parameters, high-sensitivity C-reactive protein, homocysteine, malondialdehyde, paraoxonase activity, and arylesterase activity were measured before transplant and at 1, 6, and 12 months after the transplant. Results: The levels of homocysteine and malondialdehyde did not change significantly in patients who received either tacrolimus or cyclosporine. The high-sensitivity C-reactive protein was decreased (tacrolimus group, 1 mo) and increased (cyclosporine group, 6 and 12 mo) after the kidney transplant. Paraoxonase activity was increased (tacrolimus group, 1 mo). Arylesterase activity was increased (tacrolimus group, 1, 6, and 12 mo; cyclosporine group, 1 and 6 mo). The percentage of change in arylesterase activity was higher at 12 months in the tacrolimus than in the cyclosporine group. Conclusions: Tacrolimus may be more effective than cyclosporine in improving risk factors for cardiovascular disease after kidney transplant.
