Summary of article contents:

1. Introduction

Nephrotoxicity is an increasing health concern worldwide, particularly associated with the use of certain medications such as aminoglycosides, notably gentamycin, which can damage renal function. This study investigates the protective effects of a dipeptidyl peptidase-4 (DPP-4) inhibitor, specifically sitagliptin, and the antioxidant glutathione against nephrotoxicity induced by gentamycin in Wistar albino rats. The aim is to explore the potential of combining these two agents to ameliorate renal damage and improve renal function.

2. Effects of Gentamycin-Induced Nephrotoxicity

Gentamycin, a commonly used antibiotic, is known for its nephrotoxic effects, primarily characterized by tubular necrosis and an elevation in renal biomarkers such as blood urea nitrogen (BUN), serum creatinine, and uric acid levels. The induced nephrotoxicity results from the accumulation of gentamycin in renal proximal tubules, leading to oxidative stress and subsequent cello death through mechanisms such as apoptosis. This creates a condition of acute renal injury, necessitating approaches for mitigation to preserve kidney health.

3. Role of DPP-4 Inhibitor and Antioxidant Combination

The study highlights the synergistic effect of combining sitagliptin with glutathione in counteracting gentamycin's nephrotoxic impacts. Each component plays a pivotal role in renal protection: sitagliptin contributes by reducing renal inflammation and oxidative stress, while glutathione acts as a potent scavenger of free radicals. Together, they significantly lower the elevated levels of renal biomarkers and assist in maintaining a near-normal renal function, indicating their potential as a therapeutic combination for nephroprotective strategies.

4. Mechanisms of Action: Oxidative Stress and Apoptosis

Sitagliptin and glutathione's mechanisms of action involve not only antioxidant properties but also anti-apoptotic effects that help alleviate the mitochondrial dysfunction caused by gentamycin. This study reports that gentamycin elevates oxidative stress markers, leading to cellular injury through lipid peroxidation and apoptosis. By preventing these harmful processes, the combination therapy enhances kidney protection—suggesting improvements in renal function and a reduction in renal tubular apoptosis through inhibition of pathways like caspase-3 activation.

5. Conclusion

The findings of this study suggest that the combination of a DPP-4 inhibitor (sitagliptin) and the antioxidant glutathione provides significant nephroprotective effects against gentamycin-induced nephrotoxicity in rats. By mitigating oxidative stress and apoptosis, this combination demonstrates a promising therapeutic strategy to preserve renal integrity during aminoglycoside treatment. However, further research including varied dosages and human clinical trials is necessary to confirm safety and efficacy for potential use in clinical settings.
