Abstract

Introduction: The efficacy of cisplatin (CPT) is dose dependent, but the risk of nephrotoxicity hinders the use of higher doses to maximize its antineoplastic effect. Ipomoea aquatica Forsk (IA) is a medicinal plant used in folklore for the treatment of many ailments.

Objectives: This study assessed the protective effect of the ethanolic leaf extract of I. aquatica (EEIA) against a rat model of CPT-induced kidney damage. Materials and

Methods: Fifty-four adult albino rats used for this study were randomized into 9 groups of 6 rats each. Rats were orally pretreated with 100, 200 and 400 mg/kg of EEIA daily for 7 days and were administered with 6 mg/kg of CPT intraperitoneally (ip) on the fifth and seventh day. On the eighth day, rats were sacrificed, blood was collected, and kidneys were excised. Plasma was extracted from blood and evaluated for renal function indices while kidneys were evaluated for oxidative stress markers and histology.

Results: The effects of CPT on the body and kidney weights were not significant (P>0.05) when compared to control. However, CPT-induced kidney damage showed significant (P<0.05) increases in creatinine, urea, uric acid, and malondialdehyde levels when compared to control. Furthermore, significant (P<0.05) decreases in superoxide dismutase, catalase, glutathione, glutathione peroxidase, total protein, albumin, sodium, chloride, potassium and bicarbonate levels were obtained in CPT-treated rats when compared to control. The kidneys of CPTtreated rats were marked by extensive tubular necrosis. However, CPT-induced nephrotoxic effects were significantly (P<0.01; 0.05) and in a dose- dependent manner reversed in EEIA pretreated rats.

Conclusion: The ethanolic leaf extract of I. aquatica Forsk contains essential constituents that can be used to treat CPT associated kidney injury.

Implication for health policy/practice/research/medical education:

This study evaluated the protective effect of the ethanolic leaf extract of I. aquatica against a rat model of cisplatin-induced kidney damage. This study observed that the ethanolic leaf extract of I. aquatica attenuate cisplatin-induced kidney damage in a dosedependent manner. This shows that the ethanolic leaf extract of I. aquatica contains essential constituents that can be used for the treatment cisplatin associated kidney damage.
