Investigation of polyvinylpyrrolidone-catechol-derived chitosan nanoconjugates allowed for kidney-targeted treatment of cisplatin-induced acute kidney injury and nursing care management.

Acute kidney injury (AKI) resulting from cisplatin (Cs) chemotherapy presents a significant challenge in clinical management. The study aimed to fabricate a novel compound Polyvinylpyrrolidone-catechol-derived chitosan nanoconjugates (PCChi-NC) for targeting Cs-induced AKI. Characterization studies utilizing UV-visible spectrophotometry, FT-IR, XRD, and TEM revealed a spherical morphology with diameters ranging from 20 to 60 nm. In vitro assessments utilizing HEK 293 cell lines demonstrated the biocompatibility of PCChi-NC without eliciting toxic effects. Furthermore, PCChi-NC exhibited a notable reduction in Cs-induced cell death in kidney cells, as evidenced by biomarker analysis. Anti-inflammatory analysis of mouse kidney homogenates revealed a decrease in TNF-α and IL-1β levels, indicative of the therapeutic efficacy of PCChi-NC in mitigating Cs-induced kidney inflammation. Moreover, In vivo, experimental analysis was evidenced by stable body weight and histopathological changes in mice. Our findings highlight the potential of PCChi-NC as a promising candidate for targeted therapy in Cs-induced AKI, owing to its unique renal targeting capacity.
