Renoprotective Role of Vitamin C and Coenzyme Q10 in Nephrotoxicity

Официальное название

The Potential Renoprotective Effect of Vitamin c and Coenzyme q10 Against Cisplatin Induced Nephrotoxicity in Cancer Patients

Обзор

Cisplatin is a widely used chemotherapy drug for many solid tumors (e.g., lung, bladder, ovarian, head and neck cancers). Despite its efficacy, its clinical use is limited by severe side effects, mainly nephrotoxicity, which occurs in \~30% of patients after treatment. Once inside cells, cisplatin undergoes activation, leading to DNA and mitochondrial damage, oxidative stress, inflammation, apoptosis, and eventual acute kidney injury (AKI) or chronic kidney disease (CKD). Vitamin C (ascorbic acid) is a water-soluble antioxidant with broad protective roles, including free radical scavenging, DNA and protein protection, and glutathione restoration. Coenzyme Q10 (CoQ10) is a lipid-soluble antioxidant involved in mitochondrial energy production and regeneration of other antioxidants (vitamins C \& E). Both antioxidants are generally safe at studied doses, with only mild gastrointestinal side effects reported. Therefore, evaluating their role in preventing cisplatin-induced nephrotoxicity in cancer patients is clinically valuable. Aim of the study : This study aims to evaluate the protective effects of (Vitamin C and Coenzyme q10) against cisplatin-induced nephrotoxicity in chemotherapy-naïve cancer patients.

Подробное описание

Cisplatin is a widely used chemotherapeutic agent in the treatment of several solid tumors; however, its clinical use is limited by nephrotoxicity, which occurs in a significant proportion of patients. Cisplatin-induced renal injury is primarily associated with oxidative stress, inflammation, and mitochondrial dysfunction leading to tubular cell damage.

Vitamin C is a potent antioxidant that scavenges reactive oxygen species and may reduce oxidative damage in renal tissues. Coenzyme Q10 is an essential component of the mitochondrial electron transport chain and has strong antioxidant properties that may help protect renal cells from oxidative stress and mitochondrial injury.

This randomized controlled trial aims to evaluate the potential renoprotective effects of Vitamin C and Coenzyme Q10 in chemotherapy-naïve cancer patients receiving cisplatin-based chemotherapy. Participants will be randomly allocated to receive antioxidant supplementation along with standard chemotherapy or standard therapy alone. Renal function will be monitored during treatment to assess the protective effects of these interventions.

The findings of this study may provide evidence for efficacy to reduce cisplatin-induced nephrotoxicity and improve clinical outcomes for cancer patients undergoing chemotherapy.
