Abstract:
Background: Tamoxifen is an effective drug for breast cancer treatment and its side effects
are the production of reactive oxygen species and kidney damage. As antioxidants, vitamins E and D
may help decrease kidney dysfunction.
Objectives: In the present study, the protective effects of vitamins E and D on renal toxicity caused by
tamoxifen in female Wistar rats were investigated.
Materials and Methods: Twenty-five adult female rats weighing 180-200 were randomly divided into
five groups with 5 rats. Group C, T, TE, TD, and TED were treated with olive oil, tamoxifen, tamoxifen
+ vitamin E, tamoxifen +vitamin D, and tamoxifen + both vitamins for four weeks. ELISA Kits
measured the oxidant and antioxidant tests and TNF-α in kidney tissue. The spectrophotometric method
measured urea, uric acid, and creatinine in serum and urine.
Results: Tamoxifen significantly decreased the weight of rats, GPx, CAT, SOD levels and increased
TNF-α, urinary creatinine level and, serum uric acid, urea levels (P < 0.05). But, treatment
with vitamin D and simultaneous administration of vitamins led to a significant decrease in the level
of (TNF-α) compared to the tamoxifen group (p < 0.01). Also, the histopathology results showed
that the simultaneous administration of vitamins has significantly resolved the damage caused by
the use of tamoxifen.
Conclusion: The present study's findings showed that using vitamins E and D prevents kidney damage
through antioxidant and anti-inflammatory effects. In addition, using vitamins E and D probably
showed stronger synergistic effects against kidney damage.
