Objective: The objective of this study was to assess the relationship between serum procalcitonin (PCT) and acute kidney injury (AKI) induced by bacterial septic shock. Methods: A retrospective study was designed which included patients who were admitted to the ICU from January 2015 to October 2018. Multiple logistic regression and receiver operating characteristic (ROC) as well as smooth curve fitting analysis were used to assess the relationship between the PCT level and AKI. Results: Of the 1,631 patients screened, 157 patients were included in the primary analysis in which 84 (53.5%) patients were with AKI. Multiple logistic regression results showed that PCT (odds ratio [OR] = 1.017, 95% confidence interval [CI] 1.009–1.025, p < 0.001) was associated with AKI induced by septic shock. The ROC analysis showed that the cutoff point for PCT to predict AKI development was 14 ng/mL, with a sensitivity of 63% and specificity 67%. Specifically, in multivariate piecewise linear regression, the occurrence of AKI decreased with the elevation of PCT when PCT was between 25 ng/mL and 120 ng/mL (OR 0.963, 95% CI 0.929–0.999; p = 0.042). The AKI increased with the elevation of PCT when PCT was either <25 ng/mL (OR 1.077, 95% CI 1.022–1.136; p = 0.006) or >120 ng/mL (OR 1.042, 95% CI 1.009–1.076; p = 0.013). Moreover, the PCT level was significantly higher in the AKI group only in female patients aged ≤75 years (p = 0.001). Conclusions: Our data revealed a nonlinear relationship between PCT and AKI in septic shock patients, and PCT could be used as a potential biomarker of AKI in female patients younger than 75 years with bacterial septic shock.

Background: Early detection of suspected critical patients infected with coronavirus disease 2019 (COVID-19) is very important for the treatment of patients. This study aimed to investigate the role of COVID-19 associated coagulopathy (CAC) to preview and triage. Methods and Results: A cohort study was designed from government designated COVID-19 treatment center. CAC was defined as International Society on Thrombosis and Haemostasis (ISTH) score ≥2. Data from 117 patients COVID-19 were reviewed on admission. The primary and secondary outcomes were admission to Intensive Care Unit (ICU), the use of mechanical ventilation, vital organ dysfunction, discharges of days 14, 21 and 28 from admission and hospital mortality. Among them, admission to ICU was increased progressively from 16.1% in patients with non-CAC to 42.6% in patients with CAC (P < 0.01). Likely, invasive ventilation and noninvasive ventilation were increased from 1.8%, 21.4% in patients with non-CAC to 21.3%, 52.5% in patients with CAC, respectively (P < 0.01). The incidences of acute hepatic injury and acute respiratory distress syndrome in non-CAC and CAC were 28.6% vs. 62.3%, 8.9% vs. 27.9%, respectively (P < 0.01). The discharges of days 14, 21 and 28 from admission were more in non-CAC than those of CAC (P < 0.05). Multiple logistic regression results showed that ISTH score ≥2 was obviously associated with the admission to ICU (OR 4.07, 95% CI 1.47-11.25 P = 0.007) and the use of mechanical ventilation (OR 5.54, 95% CI 2.01-15.28 P = 0.001) in patients with COVID-19. Conclusion: All results show ISTH score ≥2 is an important indicator to preview and triage for COVID-19 patients.

Objective This study aims to assess the relationship between serum procalcitonin (PCT) and acute kidney injury (AKI) induced by sepsis shock.Methods A case-control study was designed which included patients that admitted in intensive care unit (ICU) between January 2015 and October 2018. The worst values of biochemical parameters in the first 48 hours from septic shock admission to ICU were evaluated. According to KDIGO guideline, these patients were divided into AKI and non-AKI groups.Results Of 1631 patients screened, 157 patients were included in the primary analysis in which 84 (53.5%) patients with AKI. Multiple logistic regression results showed that PCT (OR=1.017, 95% CI 1.009- 1.025, P<0.001) was associated with AKI induced by septic shock. The ROC analysis showed that the cutoff point for PCT to predict AKI development was 14 ng/ml, and with a sensitivity 63%, specificity 67%. Specifically, in multivariate piecewise linear regression, the occurrence of AKI decreased with the elevation of PCT when PCT was between 25mol/L and 120 mol/L (OR 0.963, 95% CI 0.929-0.999; P= 0.042). The AKI increased with the elevation of PCT when PCT was either less than 25mol/L (OR 1.077, 95% CI 1.022-1.136; P= 0.006) or more than 120mol/L (OR 1.042, 95% CI 1.009-1.076; P= 0.013). Moreover, the PCT level was significant higher in AKI group only in female patients with age under 75(P=0.001).Conclusions Our data revealed a nonlinear relationship between PCT in 48 hours admission to ICU and AKI in septic shock patients and PCT could be used as a biomarker of AKI only in female patients under 75 years with sepsis shock.

Background Complication of disseminated intravascular coagulation (DIC) is a determinant of the prognosis in patients with sepsis shock. Procalcitonin (PCT) has been advocated as a marker of bacterial sepsis. The purpose of this study was to evaluate the relationship between serum PCT levels and DIC with sepsis shock Methods A cohort study was designed which included patients that admitted in intensive care unit (ICU) between January 1, 2015 and December 31, 2018 and the follow-up to discharge. 164 septic shock patients were divided into DIC and non-DIC groups according to international society of thrombosis and homeostasis (ISTH). PCT was measured at the admission to ICU, and all the participants received routine biochemical coagulation test subsequently. Results PCT levels were considerably higher in septic shock patients who developed DIC than those who did not (54.6[13.6–200]vs12.6[2.4–53.3]ng/ml), respectively, P < 0.001). Multivariable logistic regression model revealed that PCT level was significantly associated with risk of DIC independent of conventional risk factors. In addition, curve fitting showed a linear relationship between PCT and DIC score. The Receiver Operating characteristic(ROC) curve suggested that the optimal cut-off point for PCT to predicting DIC induced by septic shock was 42.0 ng/ml, and the area under the curve (AUC) was 0.701(95% CI [0.619–0.784], P < 0.001). More importantly, incorporating PCT with other risk factors into the prediction model significantly increased the AUC for prediction of DIC induced by sepsis shock (0.801vs 0.706; P = 0.012). Conclusions Our study suggests that PCT levels on admission is significantly and independently associated with DIC development subsequently with septic shock, combining PCT levels with other risk factors could significantly improve the prediction of DIC induced by sepsis shock.

Objectives: To investigated the relationships between procalcitonin (PCT) and disseminated intravascular coagulation (DIC) during septic shock. Methods: A retrospective study was performed, which included septic shock patients admitted into intensive care unit (ICU) from January 1, 2015 to December 31, 2018. DIC was defined as international society of thrombosis and homeostasis criteria (ISTH≥5). PCT was based on the first value after admission into ICU and the routine biochemical coagulation data based on the worst value extracted from electronic medical records within 24 hours on admission into ICU.Results: Among 2156 patients screened, 164 patients with septic shock were included in the finally analysis and 35.4% (58/164) of whom developed DIC after admission. PCT level was significantly higher in septic shock patients who developed DIC than those who did not (54.6[13.6-200] vs12.6[2.4-53.3] ng/ml, P <0.001). Multivariable logistic regression revealed that PCT (OR=1.011, 95% CI 1.006- 1.016, P<0.001) was associated with DIC during septic shock. Curve fitting showed a positive correlation between PCT and DIC. The Receiver Operating characteristic (ROC) curve suggested that the cut-off point for PCT to predict DIC during septic shock was 42.1ng/ml, with sensitivity 60.34%, specificity72.74% and the area under the curve (AUC) 0.701(95% CI [0.619-0.784], P<0.001). Interestingly, PCT increased early detection of DIC during septic shock compared with other risk factors(P=0.012)Conclusions: Our data suggest that PCT level over 42.1ng/ml on admission is associated with DIC during septic shock, and PCT is a potential predictive factor of DIC induced by septic shock at early stage.
