RESUMEN
Objective To investigate the prognostic significance of serum VE-cadherin in patients with septic shock. Methods A prospective observation study was performed between January 2016 and December 2017, forty-eight septic shock patients from intensive care unit (ICU) were enrolled, and 25 healthy volunteers served as the controls. Meanwhile, patients in the septic shock group were divided into two subgroups of the survival and death groups according to the 28-day mortality. The dynamic value changes of serum VE-cadherin (VE-Cad), vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were monitored on the 1st, 3rd and 7th day after admission. Results The serum VE-Cad level of the septic group was significantly higher than that of the control group on the 1st day (3.02±0.18 ng/mL vs. 0.26±0.05 ng/mL, t=3.275, P=0.002). There was a positive correlation between VE-Cad level and VEGF, TNF-α and IL-6 (r=0.826, 0.723, and 0.870, respectively; P<0.01). The PaO2/FiO2 and serum albumin (ALB) level of the death group were lower than that of the survival group, and extravascular lung water index (EVLWI), serum lactate, mechanical ventilation time, 7 day fluid balance, APACHE Ⅱ and SOFA levels of the death group were higher than those of the survival group. The serum VE-Cad levels of the death group were higher than those of the survival group on the 1st, 3rd and 7th day. The serum VE-Cad levels were positively correlated with APACHE Ⅱ and SOFA. The area under the ROC curve of VE-Cad predicting septic shock death on day 1 was 0.723 (95％CI 0.568-0.878). The sensitivity and specificity of VE-Cad with cut-off of 3.1 ng/mL in predicting septic shock death were 60％ and 70.83％, respectively. Conclusions Serum VE-Cad is positively correlated with disease severity and could predict a poor outcome in septic shock patients.
RESUMEN
Objective To evaluate the predictive value of serum macrophage migration inhibitory factor (MIF) for myocardial depression in severe sepsis patients.Methods Taken prospective study method,42 cases of severe sepsis patients were enrolled from December 2011 to June 2013.The patients were monitored by PICCO system after informing consent into ICU day,and given the corresponding treatment.According to the hemodynamic parameters were divided into two groups,myocardial depression group:cardiac index ＜ 3 L/(min· m2) and global end diastolic volume index ＞ 800 ml/m2,the remaining were in non myocardial depression group,and the patients were divided into survival group and death group according to 28-d mortality.Hemodynamic parameters and serum MIF,B-type natriuretic peptide (BNP),cardiac troponin Ⅰ (cTnI) level at the 1st,3rd,Sth day after admission.Results Fortty-two severe sepsis patients,non myocardial depression in 22 cases (non myocardial depression group),myocardial suppression in 20 cases (myocardial depression group).At 28 d,20 patients of survival (survival group),22 patients of death (death group).The serum MIF in death group was higher than that in survival group at the 1st,3rd,5th day (P ＜ 0.01) ; BNP and cTnI at the 1st day in two groups had no statistical significance (P ＞0.05),BNP and cTnI at the 3rd,5th day in death group was higher than that in survival group(P ＜ 0.01).The serum MIF at each time point in myocardial depression group was higher than that in non myocardial depression group [survival:8.70(3.53,16.80) μ g/L vs.1.20(0.80,1.77) μ g/L,2.30(1.33,8.40) μ g/L vs.0.60 (0.60,0.99) μg/L,0.50 (0.31,2.50) μg/Lvs.0.16 (0.15,0.20) μg/L;death:11.43(8.10,17.16) μ g/L vs.2.30(1.96,3.69) μ g/L,9.70(6.55,14.65) μ g/L vs.1.90(1.88,5.27) μ g/L,7.50(5.15,14.20)μ g/L vs.2.40(0.80,8.46) μ g/L] (P ＜ 0.05).The serum MIF of death patients in two groups was higher than that of survival patients (P ＜ 0.05).MIF at the 5th day had biggest prediction value,AUC was 0.952,when the cut-off point of 0.65 μg/L,the sensitivity was 100％ (22/22) and specificity was 85％ (17/20).Multivariable Logistic regression analysis results showed that only APACHE Ⅱ scores was the independent risk factor for 28-d mortality (P ＜ 0.01),while MIF couldn' t independent forecast 28-d mortality (P ＞ 0.05).Conclusions Elevation of serum MIF prompts severe sepsis patient with poor outcome,and dynamic changes of MIF is helpful to evaluate the prognosis and severity of severe sepsis patients with myocardial depression,but MIF is not an independent risk factor for predicting 28-d mortality.
RESUMEN
Objective To investigate the treatment of septic shock(SS) from upper urinary obstruction(UUO). Methods Continuous veno-venous haemofiltration(CVVH) combined with surgical method was applied to 42 SS patients from UUO. Their general conditions, liver and kidney functions, APACHE Ⅱ, therapeutic intervention scorisystem(TISS), multiple organ dysfunction syndrome (MODS), complication rate and main outcomes were analysed comparing with traditional therapies groups(n=30). Results Compared with those traditional therapies, the APACHEⅡ , MODS and TISS score decreased (P＜0.05). Thirty-seven out of 42 patients survived and the survival rate was 88.0% during ICU. Conclusion CVVH combined with surgical methods may effectively decrease the incidence of complications and mortality of SS from UUO, and the mechanism may be related to the remove of mediators of inflammation.
