Abstract:
Objective To evaluate the association between hypersensitive C reactive protein (hs-CRP) and the incidence of acute kidney injury in subarachnoid hemorrhage(SAH) patients.Methods It retrospectively recruited 213 cases of computerized tomography validated SAH patients from the neurology ICU from Beijing Tiantan Hospital between January 2012 and January 2015.The average age was (56.29±11.95) years old,and the patients were divided into AKI and non-AKI groups according to Kidney Disease: Improving Global Outcomes (KDIGO) diagnosis standards, Clinical features of AKI and Non-AKI patients including serum levels of hs-CRP were compared and multi-logistic regression was applied to find the risk factors concerning with the incidence of AKI.Receiver operating characteristics (ROC) curve was also plotted to evaluate the diagnostic value of hs-CRP towards the incidence of AKI.Results A total of 25 (11.74%) patients developed AKI.Average age of the SAH patients in both AKI and non-AKI groups were (63.60±12.21) years old vs.(55.31±11.60) years old(t=-3.33, P<0.05).The ratios of diabetics were were 28.00% vs.11.17% (χ2=5.47,P<0.05) and the ratio of proteinuria were 80.00% vs.34.57%, respectively (χ2=3.83, P<0.05).The median of serum creatinie were 63.72(51.45, 79.72)μmol/L vs.53.21(45.27, 65.62)μmol/L (P<0.05), and serum hs-CRP were (14.12±5.03)mg/L vs.(10.23±6.76)mg/L (P<0.05), and the ratios of antibiotics application were 84.00% vs.43.08% (P<0.05 for all).Multi-logistic regression analysis showed that serum hs-CRP was an independent risk factors for AKI after age, serum creatinine at admission were adjusted.[OR (95% CI) was 3.33(1.13, 9.85),P<0.05 for all].The area under curve of ROC was 0.69 (P<0.05), and the cut-off point of serum hs-CRP under the maximum Youden index was 13.85 mg/L.Conclusion Serum hs-CRP is an independent risk factor of theincidence of AKI in SAH patients, the significantly increase of serum hs-CRP might be an important predictor of the incidence of AKI in SAH patients.
