Abstract:
Background: It is well known that acute or chronic kidney injury could be due to free
radicals and pro-oxidants. This investigation aimed to monitor tacrolimus or cyclosporine blood
trough levels and anti-oxidant capacity after kidney transplantation.
Methods: There was no intervention in the routine management of transplant recipients. The
sample size (n=70) included healthy individuals and kidney-transplanted recipients (n=25 on
tacrolimus and n=10 on cyclosporine). The study population was matched for age. The attained
information was examined by using the Statistical Package (SPSS Inc, Chicago, IL, USA). The
significance level was considered as P ≤ 0.05.
Results: In healthy individuals, the mean ± SD for the capacity of antioxidants was 91.9 ± 16.6
(u/ml), which was significantly higher when compared to the mean value of 28.5 ± 22.6 (u/ml)
versus 24.7 ± 25.5 (u/ml), kidney recipients with tacrolimus versus cyclosporine (P ≤ 0.04)
as immunosuppressive drugs. The mean value of tacrolimus levels was 14.6 ± 6.4 (ng/ml). The
correlation between tacrolimus and cyclosporine trough levels and anti-oxidant capacity was 0.19
(P ≤ 0.14). There were no significant differences regarding age in cases and controls (P ≤ 0.42).
Conclusion: This study showed that the capacity of anti-oxidants in kidney transplant recipients,
those on tacrolimus or cyclosporine, might be lower than in healthy individuals. Subsequent
investigations are recommended to delve into the therapeutic consequences of the influence
of antioxidant therapies on the clinical outcomes of transplanted recipients.
