We tested the hypothesis whether midkine could represent an early biomarker of contrast-induced acute kidney injury (CIAKI) in 89 patients with normal serum creatinine undergoing PCI. Midkine, serum and urinary NGAL, and cystatin C were evaluated before and 2, 4, 8, 24, and 48 hours after PCI using commercially available kits. Serum creatinine was assessed before and 24 and 48 hours after PCI. We found a significant rise in serum midkine as early as after 2 hours (P<0.001) when compared to the baseline values. It was also significantly higher 4 hours after PCI and then returned to the baseline values after 24 hours and started to decrease after 48 hours. When contrast nephropathy was defined as an increase in serum creatinine by >25% of the baseline level 48 hours after PCI, the prevalence of CIN was 10%. Patients with CIN received significantly more contrast agent (P<0.05), but durations of PCI were similar. Midkine was significantly higher 2, 4, and 8 hours after PCI in patients with CIN. Since the “window of opportunity” is narrow in CIAKI and time is limited to introduce proper treatment after initiating insult, particularly when patients are discharged within 24 hours after the procedure, midkine needs to be investigated as a potential early marker for renal ischemia and/or nephrotoxicity.

AbstractObjectives:This study was designed to find the reliability of serum NGAL as an early and better diagnostic biomarker than that of serum creatinine for acute kidney injury after percutaneous coronary intervention in Pakistani population.Materials and methods:One hundred and fifty-one patients undergoing elective percutaneous coronary intervention were included and demographic data were recorded. Blood was drawn by venipuncture in clot activator vacutainers and serum was separated and stored at 4°C. Sample was drawn before the percutaneous procedure and subsequently sampling was done serially for 5 days.Results:The mean±SD serum NGAL pre-PCI (39.92± 10.35 μg/L) and 4 h post-PCI (100.42±26.07 μg/L) showed highly significant difference (p<0.001). The mean±SD serum creatinine pre-PCI (70.1±11.8 μmol/L) and post-PCI (71.2±11.6 μmol/L) showed significant difference (p=0.005) on day 2 onwards but mean microalbumin showed insignificant results (p=0.533). The serum NGAL predicted CI-AKI with sensitivity of 95.8% and specificity of 97.6% for a cut off value of 118 μg/L.Conclusion:Our results suggest that NGAL is an excellent early diagnostic biomarker for acute kidney injury in patients undergoing elective percutaneous coronary intervention.

Acute kidney injury (AKI), mostly defined as a rise in serum creatinine concentration of more than 0.5 mg/dl, is a common, serious, and potentially preventable complication of percutaneous coronary intervention and is associated with adverse outcomes including an increased risk of inhospital mortality. Recent data from the National Cardiovascular Data Registry/Cath-PCI registry including 985,737 consecutive patients undergoing percutaneous coronary intervention suggest that approximately 7% experienced AKI with a reported incidence of 3–19%. In patients undergoing primary percutaneous coronary intervention for acute myocardial infarction (AMI), AKI occurs more frequently with rates up to 20% depending on patient and procedural characteristics. However, varying definitions of AKI limit comparisons of AKI rates across different studies. Recently, most studies have adopted the Acute Kidney Injury Network (AKIN) criteria for definition and classification of AKI. Beyond the AKIN criteria for AKI, other classifications such as the risk, injury, failure, loss and end-stage kidney disease (RIFLE) and kidney disease: improving global outcomes (KDIGO) criteria are used to define AKI. Notably, even small increases in serum creatinine beyond AKI may be associated with adverse outcomes including increased hospital length of stay and excess. Acute kidney injury (AKI) is a serious and potentially preventable complication of percutaneous coronary intervention (PCI). Worsening renal function is associated with adverse outcomes including a higher rate of in-hospital mortality. In patients undergoing primary PCI for acute myocardial infarction (AMI), AKI occurs up to 20% of such individuals. Varying definitions of AKI limit comparisons of AKI rates across different studies. Additionally, even small increases in serum creatinine beyond lavels meeting AKI definitions may be associated with adverse outcomes including increased hospital length of stay.

Abstract Background Acute kidney injury (AKI) is a known complication following percutaneous coronary intervention (PCI), and is associated with higher rates of complications. We sought to determine the potential impact of temporal changes on the rates of AKI over time, as well as possible determinants of risk. Methods From a large prospective registry of patients undergoing PCI, 20,032 consecutive patients were assessed at two time periods: 2006–2012 and 2012–2018. Of these, included were cases for which data existed regarding change in creatinine levels from baseline to 48 hours after PCI. AKI was defined according to two methods- a relative elevation of ≥25% in serum creatinine or an absolute elevation of ≥0.5 mg/dL in serum creatinine at 48 hours. Results 15,153 patients were available for final analysis, 7,913 in the first period and 7,240 in the second. Mean age was 65.0y and 66.0y (p&lt;0.01) and baseline creatinine was 1.08 mg/dL and 1.15 mg/dL respectively (p&lt;0.01, table 1). AKI according to 25% relative rise in serum creatinine was documented in 11.1% in the early period and in 7.3% of the patients in the late period, p&lt;0.01. According to the definition of 0.5 mg/dL absolute rise in serum creatinine, respective rates were 3% and 2.9%, p=0.82 (figure 1). Multivariate analysis demonstrated a lower risk of AKI in the late period (OR- 0.72; CI 0.61–0.85, P&lt;0.01). Factors associated with risk of AKI included reduced ejection fraction (OR-0.98; CI 0.976–0.99, p&lt;0.01), older age (OR-1.01; CI 1.005–1.02, p=0.01) and female gender (OR- 1.73; CI 1.46–2.06, p&lt;0.01). Conclusions We have witnessed an improvement in the rates of post-PCI AKI over time. Further research is warranted, to further reduce peri-procedural AKI. Figure 1.

Abstract Background Age >75 years had been generally considered to be an important and independent risk factor of contrast-induced acute kidney injury (CI-AKI), while these patients often suffer from malnutrition. However, the predictive value of objective nutritional status for CI-AKI in elderly patients undergoing percutaneous coronary intervention (PCI) remains unknown. Purpose To evaluate the association of two kinds of objective nutritional indices includes controlling nutritional (CONUT) score and prognostic nutritional index (PNI) with CI-AKI in elderly patients undergoing PCI. Methods In a single center prospective cohort study,we enrolled 714 consecutive patients who aged >75 years undergoing PCI between January 2012 and December 2015 were screened based on their serum albumin, lymphocyte count, and total cholesterol measures. Patients were stratified into different groups according to two kinds of objective nutritional scores. Patients were divided into low-PNI (PNI <35), middle-PNI (35 ≤ PNI <38), and high-PNI (PNI ≥38). They were also divided into four groups according to CONUT score: normal-CONUT (0–1), mild-CONUT (2–4), moderate-CONUT (5–8), and severe-CONUT (≥9). CI-AKI was defined as an increase in the serum creatinine levels of ≥50% or 0.3 mg/dL above the baseline level within 48hrs after contrast medium exposure. Results Overall, 55 (7.7%) had moderate-severe CONUT scores, and 35 (4.9%) had low-middle PNI scores,while 93 (13.0%) patients developed CI-AKI. Patients with a lower PNI score or higher CONUT score had significantly higer incidence of CI-AKI [PNI score: high (11.8%), middle (33.3%), and low (45.5%), respectively; P<0.0001; CONUT score: normal (9.6%), mild (12.7%), moderate (30.2%), and severe (100%), respectively; P<0.0001]. After adjusting 6 confounders, including age, serum creatinine (SCR) >1.5mg/dl, left ventricular ejection fraction (LEVF) <45%, myocardial infarction, peri-hypotension and the contrast volume >200 ml, multivariate analysis showed that worse objective nutritional status (either lower PNI scores or higer CONUT scores) was associated with an increased CI-AKI risk (Low PNI vs High PNI: OR: 5.274, P=0.015; Moderate-Severe CONUT vs Normal CONUT: OR: 2.891, P=0.007). Incidence of CIAKI Conclusions Worse objective nutritional status was associated with CI-AKI in elderly patients after PCI.

Early Biomarker

Acute kidney injury is an important complication in hospitalized patients often diagnosed late and associated with high mortality and morbidity. Although biomarkers for nephrotoxicity are available, they often lack sensitivity and specificity for detecting tubular injury. Netrin-1 is a laminin-like molecule highly expressed in many organs including kidney. To determine the value of netrin-1 as a biomarker of renal injury, we analyzed its urinary excretion following ischemia-reperfusion-, cisplatin-, folic acid-, and endotoxin-induced renal injury in mice. Urinary netrin-1 levels increased markedly within 3 h of ischemia-reperfusion (40 ± 14-fold, P < 0.01 vs. baseline), reached a peak level at 6 h, and decreased thereafter, returning to near baseline by 72 h. Serum creatinine significantly increased only after 24 h of reperfusion. Similarly, in cisplatin-, folic acid-, and lipopolysaccharide-treated mice, urine netrin-1 excretion increased as early as 1 h and reached a peak level at 6 h after injection. However, serum creatinine was raised significantly after 6, 24, and 72 h after folic acid, lipopolysaccharide, and cisplatin administration, respectively. NGAL excretion in folic acid- and lipopolysaccharide-treated mice urine samples could only be detected by 24 h after drug administration. Furthermore, urinary netrin-1 excretion increased dramatically in 13 acute renal failure patients, whereas none was detected in 6 healthy volunteer urine samples. Immunohistochemical localization showed that netrin-1 is highly expressed in tubular epithelial cells in transplanted human kidney. We conclude that urinary netrin-1 is a promising early biomarker of renal injury.
