- Conclusion
CI-AKI is defined as an elevation in serum creatinine (Scr) by at least 0.5 mg/dl or 25% from baseline within 48 hours after contrast governance, in the absence of other causes of renal impairment. The condition is closely linked to factors such as advanced age, systemic arterial hypertension, diabetes mellitus, and the volume and osmolarity of the contrast medium used. The consequences of CI-AKI can range from mild renal dysfunction to severe renal failure requiring renal replacement therapy.
Risk Factors and Consequences
The incidence of CI-AKI is strongly associated with the number of contrast administrations. Patients with pre-existing conditions like diabetes or hypertension are at higher risk. The condition not only prolongs hospital stays but also increases the risk of cardiovascular events, renal complications, and all-cause mortality. Early detection and intervention are crucial to mitigating these risks.
The Role of Biomarkers in Early Detection
Conventional biomarkers like serum creatinine and urine output have limitations in detecting AKI at an early stage. However, novel biomarkers such as kidney injury molecule-1 (KIM-1) and tissue inhibitor of metalloproteinase-2 (TIMP-2) are revolutionizing the diagnosis and management of CI-AKI.
KIM-1, a transmembrane glycoprotein, is expressed in epithelial cells and plays a critical role in predicting kidney vulnerability to CI-AKI.High concentrations of KIM-1 in urine can indicate early renal function changes, offering a basis for early diagnosis and intervention. Studies have shown that KIM-1 levels can also predict cardiovascular events and overall mortality, making it a valuable tool in patient care.
TIMP-2, another promising biomarker, is part of the tissue inhibitor of metalloproteinases family. It has been reported to identify patients at risk for AKI, with urinary TIMP-2 levels serving as a predictive marker for the condition.

A groundbreaking study conducted at The Second Xiangya Hospital of Central South University has identified three urinary biomarkers—KIM-1,TIMP-2,and sTREM-1—as potential predictors of contrast-induced acute kidney injury (CI-AKI) in elderly patients undergoing percutaneous coronary intervention (PCI).This research,published in 2022,could revolutionize how clinicians monitor and prevent kidney damage following heart procedures.
What is CI-AKI?
CI-AKI is a serious complication that can occur after the administration of contrast media during PCI, a common procedure used to treat conditions like unstable angina and acute myocardial infarction. The condition is diagnosed when serum creatinine (Scr) levels rise by more than 25% from baseline within 48–72 hours after contrast exposure, or when absolute scr increases by ≥ 5 mg/L (44 μmol/L), excluding other causes of acute renal impairment.
The study, which involved 136 patients, aimed to explore the predictive value of urinary biomarkers in identifying CI-AKI risk. Patients were divided into two groups: those who developed CI-AKI (n = 36) and those who did not (n = 100).
The Role of Biomarkers
The researchers focused on three key biomarkers:
- Kidney Injury Molecule-1 (KIM-1): A protein released during kidney damage.
- Tissue Inhibitor of Metalloproteinases-2 (TIMP-2): A marker associated with cellular stress and injury.
- Soluble Triggering Receptor Expressed on Myeloid Cells-1 (sTREM-1): A soluble form of TREM-1, an innate immune receptor upregulated during inflammation.
Blood and urine samples were collected before PCI and at 6, 12, 24, and 48 hours post-procedure.The samples were analyzed using enzyme-linked immunosorbent assay (ELISA) kits from Amyjet Scientific Inc.
Key Findings
The study revealed significant differences in urinary KIM-1,TIMP-2,and sTREM-1 levels between CI-AKI and non-CI-AKI patients. These biomarkers showed promise in early detection, potentially allowing clinicians to intervene before significant kidney damage occurs.
| biomarker | Role in CI-AKI Prediction |
|—————|——————————-|

These findings, published across multiple studies, highlight the critical role of urinary biomarkers and inflammatory markers in predicting and managing contrast-induced nephropathy (CIN), a serious complication that can arise after these procedures. A study by Wybraniec et al. (2017) demonstrated that early post-procedural analysis of urinary biomarkers, such as kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL), combined with intra-renal doppler flow indices, can effectively predict the onset of CIN in patients undergoing coronary angiography. This non-invasive approach offers a promising tool for clinicians to identify at-risk patients before significant kidney damage occurs. Similarly, Huyut (2021) found that elevated levels of KIM-1 are strongly associated with CIN in elderly patients with non-ST-segment elevation myocardial infarction (non-STEMI). This underscores the biomarker’s potential as a reliable indicator of kidney injury in vulnerable populations. Further supporting these findings, Wang and Pu (2014) emphasized the predictive value of monitoring changes in NGAL and KIM-1 levels after coronary procedures.

Beyond urinary biomarkers, inflammatory markers like TREM-1 have also emerged as critical players in kidney injury and disease. wang et al. (2017) discovered that increased serum levels of TREM-1 are linked to in-stent restenosis, a condition where blood vessels narrow again after stent placement. Their study also showed that TREM-1 activation promotes inflammation,proliferation,and migration in vascular smooth muscle cells,contributing to vascular complications. In the context of kidney disease,zhao et al. (2018) found that TREM-1 contributes to inflammation in IgA nephropathy, a common form of kidney disease. This highlights the marker’s broader role in renal pathology and its potential as a therapeutic target. Moreover, Pan et al. (2021) demonstrated that TREM-1 promotes apoptosis and inhibits autophagy in kidney cells treated with lipopolysaccharide (LPS), a bacterial toxin.This process is mediated through the NF-kappaB pathway, further solidifying TREM-1‘s role in kidney injury and inflammation. Another significant advancement comes from schanz et al. (2023), who explored the role of TIMP-2 and IGFBP7 in human kidney biopsies. Their research revealed that these biomarkers are elevated in various renal diseases, offering new insights into the mechanisms of kidney injury and potential avenues for treatment. the integration of these biomarkers into clinical practice could transform the management of kidney injury, particularly in high-risk patients undergoing coronary procedures.

Breakthrough Research Unveils New Biomarkers for Early detection of Kidney Injury After Coronary Procedures In a groundbreaking growth, researchers have identified key biomarkers that could revolutionize the early detection of kidney injury following coronary angiography and percutaneous coronary intervention (PCI). These findings, published across multiple studies, highlight the critical role of urinary biomarkers and inflammatory markers in predicting and managing contrast-induced nephropathy (CIN), a serious complication that can arise after these procedures. A study by Wybraniec et al. (2017) demonstrated that early post-procedural analysis of urinary biomarkers, such as kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL), combined with intra-renal doppler flow indices, can effectively predict the onset of CIN in patients undergoing coronary angiography. This non-invasive approach offers a promising tool for clinicians to identify at-risk patients before notable kidney damage occurs. Similarly,Huyut (2021) found that elevated levels of KIM-1 are strongly associated with CIN in elderly patients with non-ST-segment elevation myocardial infarction (non-STEMI).this underscores the biomarker’s potential as a reliable indicator of kidney injury in vulnerable populations. Further supporting these findings, Wang and Pu (2014) emphasized the predictive value of monitoring changes in NGAL and KIM-1 levels after coronary procedures.Their research revealed that these biomarkers could serve as early warning signs, enabling timely intervention to prevent CIN. Beyond urinary biomarkers, inflammatory markers like TREM-1 have also emerged as critical players in kidney injury and disease. Wang et al. (2017) discovered that increased serum levels of TREM-1 are linked to in-stent restenosis, a condition where blood vessels narrow again after stent placement. Their study also showed that TREM-1 activation promotes inflammation, proliferation, and migration in vascular smooth muscle cells, contributing to vascular complications. In the context of kidney disease, Zhao et al. (2018) found that TREM-1 contributes to inflammation in IgA nephropathy, a common form of kidney disease. This highlights the marker’s broader role in renal pathology and its potential as a therapeutic target. Moreover, Pan et al. (2021) demonstrated that TREM-1 promotes apoptosis and inflammation in acute kidney injury (AKI), further solidifying its importance in the pathophysiology of kidney-related conditions. These findings suggest that targeting TREM-1 could offer new avenues for treatment and prevention of kidney injury in high-risk patients. The identification and validation of these biomarkers represent a significant step forward in the early detection and management of kidney injury, particularly in high-risk populations such as those undergoing coronary procedures. By integrating these biomarkers into clinical practice,healthcare providers can improve patient outcomes and reduce the burden of complications like CIN and AKI. As research continues, the medical community must focus on validating these biomarkers in larger, more diverse populations. Collaborative efforts between researchers, clinicians, and policymakers will be essential to translate these findings into real-world applications.

These findings, published across multiple studies, highlight the critical role of urinary biomarkers and inflammatory markers in predicting and managing contrast-induced nephropathy (CIN), a serious complication that can arise after these procedures. The Role of Urinary Biomarkers in Predicting CIN A study by Wybraniec et al. (2017) demonstrated that early post-procedural analysis of urinary biomarkers, such as kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL), combined with intra-renal doppler flow indices, can effectively predict the onset of CIN in patients undergoing coronary angiography. This non-invasive approach offers a promising tool for clinicians to identify at-risk patients before notable kidney damage occurs. Similarly,Huyut (2021) found that elevated levels of KIM-1 are strongly associated with CIN in elderly patients with non-ST-segment elevation myocardial infarction (non-STEMI).this underscores the biomarker’s potential as a reliable indicator of kidney injury in vulnerable populations. Further supporting these findings, Wang and Pu (2014) emphasized the predictive value of monitoring changes in NGAL and KIM-1 levels after coronary procedures.Their research revealed that these biomarkers could serve as early warning signs, enabling timely intervention to prevent CIN. Inflammatory Markers and Kidney Disease Beyond urinary biomarkers, inflammatory markers like TREM-1 have also emerged as critical players in kidney injury and disease. Wang et al. (2017) discovered that increased serum levels of TREM-1 are linked to in-stent restenosis, a condition where blood vessels narrow again after stent placement. Their study also showed that TREM-1 activation promotes inflammation, proliferation, and migration in vascular smooth muscle cells, contributing to vascular complications. In the context of kidney disease, Zhao et al. (2018) found that TREM-1 contributes to inflammation in IgA nephropathy, a common form of kidney disease. This highlights the marker’s broader role in renal pathology and its potential as a therapeutic target. Moreover, Pan et al. (2021) demonstrated that TREM-1 promotes apoptosis and inflammation in acute kidney injury (AKI), further solidifying its importance in the pathophysiology of kidney-related conditions. These findings suggest that targeting TREM-1 could offer new avenues for treatment and prevention of kidney injury in high-risk patients. Conclusion The identification and validation of these biomarkers represent a significant step forward in the early detection and management of kidney injury, particularly in high-risk populations such as those undergoing coronary procedures. By integrating these biomarkers into clinical practice,healthcare providers can improve patient outcomes and reduce the burden of complications like CIN and AKI. As research continues, the medical community must focus on validating these biomarkers in larger, more diverse populations. Collaborative efforts between researchers, clinicians, and policymakers will be essential to translate these findings into real-world applications.
