| Summary: | Amikacin is an important antibiotic, and its use is limited because of the induced nephrotoxicity. Thus, search for natural and synthetic agents that can moderate amikacin toxicity never stopped. The present study aims to investigate the possible ameliorative effects of virgin olive oil and olive leaf extract against the amikacin-induced nephrotoxicity in rat.
Methods: 48 rats were distributed into 6 groups: 1-Animals of control (C) group were injected intraperitoneally (ip) with saline, 2-(AK); injected ip with amikacin {300 mg/kg/day for 12days}, 3-(OO) group: given olive oil {7 ml/kg/day for 16days}, 4-(OOAK) group: given olive oil as in OO and amikacin for 12days, 5-(OL) group: given olive leaf extract {50 mg/kg/day for 16days}, 6-(OLAK) group: given leaf extract as in OL and amikacin for 12days. Animals were fasted and sacrificed. Serum was used for biochemical analysis and kidneys for histopathology.
Results: Serum urea and creatinine were significantly (P < 0.001) elevated in AK, and significantly dropped in the OOAK and OLAK groups. Serum uric acid was reduced in AK by 45.29%. Kidneys from AK showed necrosis, whereas, those from OOAK and OLAK showed mild histology. The serum triglyceride was decreased by 17.8% in OL, by 37.02% in OOAK and by 31.48% in OLAK. The calculated amikacin effect showed a significant positive correlation with urea (r = 0.521, P = 0.0004), and a negative correlation with uric acid (r = − 0.58, P < 0.0001).
Conclusion: The study confirmed nephrotoxicity of amikacin in rat which was ameliorated by virgin olive oil and by olive leaf extract. Amikacin did not cause dyslipidemia but reduced serum uric acid.
