Pharmacogenetics may Influence Tacrolimus Daily Dose, but not Urinary Tubular Damage Markers in the Long-Term Period after Renal Transplantation.

Background: The primary goal of this study was to evaluate the influence of cytochrome P450 (CYP) 3A5 (6986A>G) and ABCB1 (3435C>T) polymorphisms on tacrolimus (TAC) dosage regimen and exposure. Second, we evaluated the influence of TAC dosage regimen and the tested polymorphisms on renal oxidative injury, as well as the urinary activities of tubular ectoenzymes in a long-term period after transplantation. Also, we aimed to determine the association between renal oxidative stress and tubular damage markers in the renal transplant patients.

Gender differences in oxidative and nitrosative stress parameters in kidney transplant patients on tacrolimus-based immunosuppression.

Background: Cardiovascular (CV) morbidity and mortality rates are still higher after kidney transplantation than in general population. It is known that oxidative and nitrosative stress may contribute to the progress of CV disease in a post-transplant period, but still gender aspect has not been elucidated completely. The aim of this study was to analyze the gender differences in the oxidative and nitrosative stress parameters, as well as asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) levels among kidney transplant patients on tacrolimus-based immunosuppression.

Endothelial dysfunction, inflammation and malnutrition markers as predictors of mortality in dialysis patients: multimarker approach.

Backgrounds: Cardiovascular disease is reported to be major cause of mortality in dialysis patients. Multimarker approach is new approach in risk stratification. Creating a common predictive value, many different pathophysiological components are covered.

How the duration period of erythropoietin treatment influences the oxidative status of hemodialysis patients.

Background: End-stage renal disease is a state of enhanced oxidative stress (OS) and hemodialysis (HD) and renal anemia further augment this disbalance. Anemia correction with erythropoietin (EPO) may improve oxidative status. However, there is no evidence of time dependent effects of EPO therapy on redox status of HD patients.

Protective effects of glutathione and lipoic acid against cadmium-induced oxidative stress in rat's kidney.

Cadmium is a widespread, toxic industrial pollutant. The proximal tubule of the mammalian kidney is a major target of Cd-induced toxicity. We analyzed the effects of cadmium exposure on the model system of experimental animals, the thiobarbituric acid (TBA)-reactive substance (TBARS) level, and the activity of xanthine oxidase (XO) and catalase in kidney of rats, with and without glutathione and lipoic acid (LA).
