Recently, the systemic inflammation score (SIS) has been introduced to evaluate the inflammatory status, utilizing the lymphocyte-to-monocyte ratio (LMR) and albumin. The primary objective of this study was to determine whether the SIS can predict CA-AKI and long-term prognosis in patients undergoing elective percutaneous coronary intervention (PCI).Patients and Methods: A total of 5726 patients who underwent elective PCI were included from January 2012 to December 2018. The primary outcome was CA-AKI, defined as an increase in serum creatinine (SCr) ≥ 0.3 mg/dl or ≥ 50% than baseline SCr within 48 h after the PCI procedure. The secondary outcome was long-term mortality. All patients were classified into low- and high-SIS groups.Results: During hospitalization, 349 (6.1%) patients developed CA-AKI. Multivariate logistic regression analysis showed that patients in the high SIS group had a 1.47-fold higher risk of developing CA-AKI than those in the low SIS group [odds ratio (OR): 1.50, 95% confidence interval (CI): 1.12– 2.01, P =0.006]. Furthermore, the SIS showed the greatest prediction performance for CA-AKI compared with other inflammatory hematological ratios. In the multivariate Cox regression analysis, the high SIS group was found to be closely associated with long-term mortality [hazard ratio (HR): 1.58, 95% CI: 1.26– 1.97, P < 0.001, vs low SIS group]. The Kaplan-Meier curve analysis also demonstrated a difference in long-term mortality between the two groups (Log rank test, P < 0.001).Conclusion: The SIS was closely associated with CA-AKI and long-term mortality in patients after elective PCI. Thus, more attention should be paid to exploring the potential benefits of anti-inflammatory strategies in preventing CA-AKI and improving the prognosis of patients undergoing PCI.Keywords: contrast-associated acute kidney injury, mortality, percutaneous coronary intervention, systemic inflammation score

Considering that COPD patients usually have an ongoing prothrombotic state and systemic inflammation status, we investigated the association among them and explored the predictive value of a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS-13), on concealed chronic renal failure (CRF) in COPD patients.Methods: COPD patients were recruited from the First Affiliated Hospital of Sun Yat-Sen University between January 2015 and December 2016. Control was selected from contemporaneous hospitalized patients without COPD and matched by age and gender at a ratio of 1:1. Estimated glomerular filtration rate (eGFR) was calculated by using the Chronic Kidney Disease Epidemiology Collaboration formula, and all subjects were categorized as having normal renal function (eGFR ≥60 mL min–1 1.73 m–2) and having concealed CRF (normal serum creatinine while eGFR
