Insights
Contrast-induced nephropathy (CIN) is a risk in radiological procedures, especially for high-risk patients. Prevention is key due to lack of effective treatments for this kidney injury.
Area of Science:
- Nephrology
- Radiology
- Cardiology
Background:
- Radiological procedures using iodinated contrast media can cause contrast-induced nephropathy (CIN) and hospital-acquired renal failure.
- While CIN risk is low in the general population, it significantly increases in patients with chronic kidney disease, diabetes, or undergoing emergency percutaneous coronary interventions (PCI).
- CIN leads to substantial morbidity, mortality, and increased healthcare costs, necessitating effective prevention strategies.
Purpose of the Study:
- To examine the pathophysiology, risk factors, and clinical course of CIN.
- To review recent studies on CIN prevention and potential therapeutic interventions, particularly during PCI.
Main Methods:
- Literature review of studies on contrast-induced nephropathy.
- Analysis of risk factors, pathophysiology, and clinical outcomes.
- Evaluation of prevention and treatment strategies for CIN in radiological procedures.
Main Results:
- CIN poses a significant risk, especially in vulnerable patient subsets undergoing specific procedures.
- Effective prevention strategies are crucial due to the absence of established treatments for CIN.
- Ongoing research focuses on novel preventive and therapeutic approaches for CIN.
Conclusions:
- CIN is a serious iatrogenic complication of radiological procedures, demanding proactive management.
- Patient-specific risk assessment and tailored preventive measures are essential, particularly for those undergoing PCI.
- Further research into effective CIN prevention and treatment is critical to mitigate patient harm and healthcare costs.
Abstract:
Radiological procedures utilizing intravascular iodinated contrast media are being widely applied for both diagnostic and therapeutic purposes and represent one of the main causes of contrast-induced nephropathy (CIN) and hospital-acquired renal failure. Although the risk of CIN is low (0.6-2.3 %) in the general population, it may be very high (up to 50 %) in selected subsets, especially in patients with major risk factors such as advanced chronic kidney disease and diabetes mellitus, and in those undergoing emergency percutaneous coronary interventions (PCI). Due to the lack of any effective treatment, prevention of this iatrogenic disease, which is associated with significant in-hospital and long-term morbidity and mortality and increased costs, is the key strategy. However, prevention of CIN continues to elude clinicians and is a main concern during PCI, as patients undergoing these procedures often have multiple comorbidities. The purpose of this study is to examine the pathophysiology, risk factors and clinical course of CIN, as well as the most recent studies dealing with its prevention and potential therapeutic interventions, especially during PCI.
