The exploration of therapeutic potential of bioflavonoids in metabolic acidosis and inflammation-associated with acute kidney injury: Therapeutic potential of bioflavonoids in acute kidney injury.

Objectives: The goal of this study was to estimate and compare the prospective therapeutic impacts of different types of bioflavonoids (flavonols, flavanones, and isoflavones) on acute kidney injury (AKI) induced by glycerol in male rats.

Methods: Fifty adult male albino rats (Sprague-Dawley) were separated into five groups: G1, control; G2, rats injected (i.m.) by glycerol (50%) (10 mL/kg b. w.) to induce AKI; G3, G4, and G5, rats received quercetin (QUR), hesperidin (HSP), and genistein (GEN), respectively, after 24 h of glycerol injection for 42 successive days.

Results: Treatment with bioflavonoids improved the renal tissue levels of antioxidant biomarkers (superoxide dismutase, glutathione, catalase, nitric oxide, inflammatory cytokines (interleukin-6, interleukin-1 βeta, nuclear factor kappa-B, tumor necrosis factor-alpha), kidney function markers (creatinine, urea, urine albumin creatinine ratio, albumin) as compared to nephrotoxic groups. QUR extract reduced the serum level of kidney function parameters in glycerol-injected rats more significantly (P ≤ 0.01) than HSP and GEN. Results demonstrated that the GEN as a therapeutic natural agent exhibited the greatest advancement in urine values, followed by the QUR and HSP respectively when compared to the AKI group.

Conclusion: The study results demonstrated the therapeutic effect of bioflavonoids against AKI induced by glycerol. Different types of bioflavonoids could reduce oxidative stress, inhibit the production of inflammatory mediators and cytokines, and improve renal function.
