Criteria For Diagnosis Of Sepsis Research Articles

The clinical value of high mobility group box-1 and CRP/Alb ratio in the diagnosis and evaluation of sepsis in children.

To explore the clinical value of high mobility group box-1 (HMGB-1), C-reactive protein (CRP), procalcitonin (PCT), and CRP to albumin (Alb) ratio in the diagnosis and evaluation of the severity of sepsis in children. A total of 90 children, 50 with sepsis and 40 with general infection, whose symptoms did not meet the criteria for diagnosis of sepsis, were admitted to the Pediatrics Department of Jingzhou Central Hospital in Hubei Province between November 2021 and December 2022, were enrolled and selected as experimental and control group, respectively. The serum of two groups was collected within 24 hours after admission, the levels of HMGB-1 were detected by enzyme-linked immunosorbent assay (ELISA), and CRP, PCT, Alb, and hospitalization days were recorded. The differences in indicators between the two groups were compared, and correlation analysis was performed between hospitalization days and various indicators. The receiver operating characteristic (ROC) curve was drawn to evaluate the independent or combined value of CRP, PCT, HMGB-1, and CRP/Alb ratio in the early diagnosis of sepsis in children. These four indicators of children with sepsis were significantly higher than those in the general infection group (all p=0.000). The levels of CRP, PCT and CRP/Alb ratio were significantly positively correlated with the hospitalization days (r=0.329, 0.333, 0.329; p=0.02, 0.01, 0.002). The area under curve (AUC) of CRP, PCT, HMGB-1, and CRP/Alb ratio for the diagnosis of sepsis in children was 0.798, 0.817, 0.838, 0.809, respectively, and that of the combination of four indicators was 0.952. CRP, PCT, HMGB-1, and CRP/Alb ratio resulted as effective indicators for early diagnosis and evaluation of childhood sepsis, having a higher value in combined diagnosis.

Endogenous thrombin potential as marker of procoagulant response that can be useful in early stage of sepsis.

: Sepsis is associated with complex procoagulant and anticoagulant changes that modify inflammatory response. Identification of coagulation markers that can differentiate useful procoagulant response from adverse alteration of clotting mechanism in patient with sepsis. In total, 150 patients who fulfilled criteria for diagnosis of sepsis were included in this study. Patients were categorized in two groups according to sepsis severity in the first 24 h from intensive care unit admission: sepsis and septic shock. In total, 28-day mortality was assessed. Platelet count, activated partial thromboplastin time, prothrombin time, D-dimer, fibrinogen, protein C, protein S, antithrombin levels, and endogenous thrombin potential were determined within first 24 h from ICU admission. Differences between groups of septic patients were assessed by Mann-Whitney U test. Categorical variables were compared using χ test. Receiver operating characteristic curves were plotted to determine predictive values of variables for sepsis severity prediction. Activated partial thromboplastin time and prothrombin time were significantly prolonged with higher D-dimer, lower fibrinogen, and natural anticoagulant levels (protein C, protein S, and antithrombin) in patients with more severe form of the disease and worse outcome (P < 0.05). Endogenous thrombin potential [area under the curve (AUC) %] was significantly decreased in patients with more severe form of sepsis (66.01 ± 41.51 vs. 83.21 ± 28.83; AUC 0.76) and in patients with worse outcome (67.66 ± 37.79 vs. 81.79 ± 32.15; AUC 0.68; P < 0.05). Evaluation of initial thrombin generation is useful to distinguish between beneficial coagulation activation and hazardous haemostatic alteration, and to predict multiorgan dysfunction development and poor outcome in septic patients.

Sepsis in Obstetrics: Treatment, Prognosis, and Prevention.

Sepsis during pregnancy is one of the five leading causes of maternal mortality worldwide. Early recognition and prompt treatment of maternal sepsis is necessary to improve patient outcomes. Patient education on practices that reduce infections may be helpful in decreasing rates of sepsis. Education of nurses about early signs and symptoms of sepsis in pregnancy and use of obstetric-specific tools can assist in timely identification and better outcomes. Although the Surviving Sepsis Campaign (SSC) criteria for diagnosis of sepsis in the general population are not pertinent for obstetric patients, their treatment bundles (guidelines) are applicable and can be used to guide care of obstetric patients who develop sepsis.This article is the third in a series of three that discuss the importance of sepsis and septic shock in pregnancy. This article includes case studies, treatment, prognosis, education, and prevention of maternal sepsis.

Evaluation of the systemic inflammatory response syndrome criteria for the diagnosis of sepsis due to maternal bacteremia.

To examine, in the setting of maternal bacteremia, the implications for the diagnosis of maternal sepsis of customizing the systemic inflammatory response syndrome (SIRS) criteria for physiologic changes of pregnancy. Women with maternal bacteremia in a tertiary maternity hospital during 2009-2014 were identified. Records were retrospectively reviewed to determine whether they fulfilled the criteria for diagnosis of sepsis based on either the standard SIRS parameters derived from the Surviving Sepsis Campaign or SIRS parameters customized for pregnancy. Diagnosis of sepsis was based on the presence of two or more SIRS criteria, in conjunction with infection, during the hour before and the 6 hours after phlebotomy for blood culture. Of 93 women with bacteremia, 61 (66%) would have been diagnosed with sepsis based on standard criteria compared with 52 (56%) based on customized criteria (P=0.18). Seventeen women had a diagnosis of sepsis based on the standard but not the customized criteria, while eight women had sepsis based on the customized but not the standard criteria. In maternal bacteremia, customized SIRS criteria do not increase the rate of diagnosis of sepsis. Prospective studies should investigate whether the introduction of customized SIRS criteria can improve clinical outcomes.

Endocan is useful biomarker of survival and severity in sepsis

IntroductionCoagulation abnormalities which occur as a consequence of endothelial changes are recognized as diagnostic criteria for sepsis, but significance of these changes in the outcome prognosis and prediction of the course of sepsis is still not accurately defined. Materials and methods60 patients who fulfilled the criteria for diagnosis of sepsis were included in our study. Patients were categorized in two groups according to sepsis severity and organ failure and MODS development was assessed in the first 48h from ICU admission. Prothrombin time (PT), activated partial thromboplastin time (aPTT) and endothelial cell specific molecule-1(endocan) levels, as well as procalcitonin (PCT) and C-reactive protein (CRP) were determined within the first 24h of the onset of the disease. Predictive APACHE II (Acute Physiology and Chronic Health Evaluation II) and SOFA (Sequential Organ Failure Assessment) scores were calculated on the day of ICU admission. Data were used to determine an association between day 1 biomarker levels, organ dysfunction score values and the development of organ failure, multiple organ dysfunction syndrome (MODS), and mortality during 28days. These connections were determined by plotting of receiver operating characteristic (ROC) curves. Differences between groups were assessed by Mann–Whitney U test. Categorical variables were compared using chi-square test. ResultsConcentration of endocan was significantly higher in the group of patients with sepsis induced organ failure, MODS development and in the group of non- survivors in contrast to group with less severe form of the disease, without multiorgan failure, and in contrast to group of survivors (p<0.05). Values of areas under the ROC curves showed that endocan levels had good discriminative power for more severe course of sepsis, MODS development and possible discriminative power for mortality prediction (AUC: 0.81, 0.67, 0.71 retrospectively), better than PCT for fatality (AUC:053) and better than APACHE II (AUC:0.55) and SOFA (AUC: 0.57) scores for organ failure. ConclusionsResults of our study show that endocan can be used as strong and significant predictor of sepsis severity and outcome, perhaps even better than SOFA and APACHE II scores.

Thrombomodulin is a Strong Predictor of Multiorgan Dysfunction Syndrome in Patients With Sepsis

Biomarkers of endothelial dysfunction are not recommended for routine laboratory investigation of the outcome prognosis and prediction of the course of sepsis. A total of 60 patients who fulfilled the criteria for diagnosis of sepsis were included in our study. Development of multiorgan dysfunction syndrome (MODS) in the first 48 hours was assessed. Differences between groups of patients with sepsis were assessed by Mann-Whitney U test and by Kruskal-Wallis test. Logistic regression analysis was performed to test the joint effect of different predictors. Level of thrombomodulin was significantly higher in group of patients with MODS than without MODS (P = .015). Levels of antithrombin (P = .026) and protein C (P = .035) were significantly lower in patients with MODS. Level of thrombomodulin was the strongest predictor in MODS development in first 48 hours (P = .028). The level of thrombomodulin not only was able to distinguish the severity of sepsis but also was a significant predictor of MODS development.
