Abstract:
Acute kidney injury in critically ill patients is common and associated with a substantial increase in morbidity and mortality. Even with aggressive medical care and renal replacement therapy, acute kidney injury remains a significant health care concern. Recent published reports offer new strategies for the prevention and amelioration of acute kidney injury using carbon monoxide. Although considered a toxic environmental gas, carbon monoxide has recently aroused scientific and clinical interest, as its beneficial effects and mechanisms of action have been substantially defined in various in vitro and in vivo experiments. The exogenous application of carbon monoxide can confer cytoprotection by modulating intracellular signaling pathways through its anti-inflammatory, anti-apoptotic, vasodilative, antithrombotic and antiproliferative properties. Thus, evidence is accumulating to support the notion of carbon monoxide treatment for acute kidney disease. In this review, we focus on the extensively analyzed advantageous value of treatment with inhaled/soluble carbon monoxide in the context of kidney injury. Mechanisms such as signaling pathways, as well as an expanded view regarding toxicity and side-effects, are described broadly. In addition, we discuss the clinical applicability of carbon monoxide as a promising therapeutic strategy for the treatment of patients with acute kidney disease based on translating basic experimental findings into clinical application.
Insights
Carbon monoxide (CO) shows promise in preventing and treating acute kidney injury (AKI) in critically ill patients. Its cytoprotective properties offer a novel therapeutic strategy for kidney disease.
Area of Science:
- Nephrology
- Toxicology
- Biomedical Engineering
Background:
- Acute kidney injury (AKI) is a prevalent and serious condition in critically ill patients, often leading to increased morbidity and mortality.
- Current treatments, including renal replacement therapy, have limitations in fully addressing AKI.
- Recent research highlights the potential of carbon monoxide (CO) as a therapeutic agent for AKI.
Purpose of the Study:
- To review the beneficial effects and mechanisms of carbon monoxide in preventing and treating acute kidney injury.
- To explore the cytoprotective properties of exogenous carbon monoxide.
- To discuss the clinical applicability of carbon monoxide therapy for acute kidney disease.
Main Methods:
- Review of in vitro and in vivo experimental findings on carbon monoxide's effects on kidney injury.
- Analysis of signaling pathways modulated by carbon monoxide.
- Evaluation of toxicity and side-effects associated with carbon monoxide administration.
Main Results:
- Carbon monoxide confers cytoprotection through anti-inflammatory, anti-apoptotic, vasodilative, antithrombotic, and antiproliferative mechanisms.
- Exogenous CO application modulates intracellular signaling pathways.
- Evidence supports the therapeutic potential of inhaled or soluble CO for kidney injury.
Conclusions:
- Carbon monoxide presents a promising therapeutic strategy for acute kidney disease.
- Translating experimental findings on CO's benefits into clinical application is crucial.
- Further research into CO's mechanisms and clinical efficacy is warranted for AKI treatment.
