Background: In this study, we aimed to investigate the diagnostic and prognostic utilities of presepsin and procalcitonin (PCT) in critically ill patients with suspected sepsis, for whom sepsis was diagnosed clinically based on the Survival Sepsis Campaign (SSC) criteria and to compare it with recent criteria of Sepsis-3. Methods: Blood samples for biomarker measurements of presepsin and PCT were drawn on days 1, 3 and 7 of ICU admission in a total of 26 patients. All patients were followed-up until death or discharge. All studied biomarkers were analyzed according to the diagnosis and severity of sepsis and for prognosis (all-cause mortality) at days 1, 3 and 7. Agreement between the diagnosis of clinical sepsis and presepsin or PCT-based sepsis was assessed using Cohen’s kappa Results: Clinical sepsis (based on Sepsis-3) and presepsin or PCT-based sepsis showed poor agreement (Kappa<0.4). Presepsin levels at day1 correlated significantly with mortality (r=0.45, P; 0.02). The diagnostic value of both presepsin and PCT to diagnose sepsis was weak (Area under curve (AUC) <0.75). The overall agreement in sepsis diagnosis was fair to good based on the both clinical criteria (P<0.05, Kappa: 0.5-0.75). More than 80% of patients (N=21) had sepsis based on presepsin upon admission. Both clinical criteria predicated that less than 20% of patients (N=5) had sepsis upon admission. Conclusion: Based on our findings, the overall agreement between the diagnosis of clinical sepsis and presepsin or PCT-based sepsis was poor. Also, our results show that the new Sepsis-3 definitions were accurate and equal to the previous definition of SSC guideline. Although, availability of diagnostic assays is variable in Iran, but, it seems that addition of developing decision tools that utilize biomarkers to help aid the rapid diagnosis of sepsis is necessary and may  improve patient outcomes.

Background QT prolongation increases the risk of ventricular arrhythmia and is common among critically ill patients. The gold standard for QT measurement is electrocardiography. Automated measurement of corrected QT (QTc) by cardiac telemetry has been developed, but this method has not been compared with electrocardiography in critically ill patients. Objective To compare the diagnostic performance of QTc values obtained with cardiac telemetry versus electrocardiography. Methods This prospective observational study included patients admitted to intensive care who had an electrocardiogram ordered simultaneously with cardiac telemetry. Demographic data and QTc determined by electrocardiography and telemetry were recorded. Bland-Altman analysis was done, and correlation coefficient and receiver operating characteristic (ROC) coefficient were calculated. Results Fifty-one data points were obtained from 43 patients (65% men). Bland-Altman analysis revealed poor agreement between telemetry and electrocardiography and evidence of fixed and proportional bias. Area under the ROC curve for QTc determined by telemetry was 0.9 (P &lt; .001) for a definition of prolonged QT as QTc ≥ 450 milliseconds in electrocardiography (sensitivity, 88.89%; specificity, 83.33%; cutoff of 464 milliseconds used). Correlation between the 2 methods was only moderate (r = 0.6, P &lt; .001). Conclusions QTc determination by telemetry has poor agreement and moderate correlation with electrocardiography. However, telemetry has an acceptable area under the curve in ROC analysis with tolerable sensitivity and specificity depending on the cutoff used to define prolonged QT. Cardiac telemetry should be used with caution in critically ill patients.

Objective: To determine the contemporary prevalence of intra-abdominal hypertension (IAH) and abdominal compartment syndrome in critically ill patients. Data Sources: Medline, Embase, and Central databases. Study Selection: Studies reporting on the prevalence of IAH in consecutively admitted critically ill patients using the World Society of Abdominal Compartment Syndrome (WSACS) consensus guidelines for intra-abdominal pressure (IAP) measurement. Data Extraction: Duplicate independent review and data abstraction. Data Synthesis: The search identified 2428 titles with 6 eligible studies (n = 1965). Reported prevalence ranged from 30% to 49%. Despite abiding by the WSACS guidelines for IAP measurement, studies varied in their definition of IAH, frequency and duration of IAP measurement, and reporting of outcomes. Three of 6 studies reported that IAH, especially at higher grades, was an independent predictor of mortality. Conclusions: Intra-abdominal hypertension is a common finding in critically ill patients and may be associated with increased mortality, especially at higher grades. Further prospective research is required to examine the effect of screening and treatment of IAH on patient outcomes.

Background: The diagnosis of sepsis is challenging in the absence of a gold standard test. Recent studies have explored the role of neutrophil and monocyte volume, conductivity, and scatter (VCS), derived from automated hematology analyzers, in diagnosing sepsis. We assessed the diagnostic accuracy of VCS parameters in critically ill patients with sepsis. Methodology: In this prospective study, VCS parameters, procalcitonin, and C-reactive protein (CRP) were assessed in patients with proven sepsis (cases) and 2 control groups (intensive care unit [ICU] patients without sepsis and healthy blood donors). The diagnostic property of each test was explored by calculating sensitivity, specificity, negative and positive predictive values, and area under the curve (AUC). Results: The study included 65 patients with sepsis, 58 nonseptic ICU controls, and 98 blood donors. Procalcitonin and CRP were not significantly different ( P > .06) between patients with sepsis and nonseptic patients. Mean (95% confidence interval [CI]) neutrophil volume (MNV) was significantly higher ( P < .001) in patients with sepsis (165.5; 95%CI 161.6-169.4) than in nonseptic (157.3; 95%CI 154.6-160.1) patients and donors (148.9; 95%CI 147.9-150). A similar pattern was seen with mean monocyte volume (MMoV). Neutrophil and monocyte conductivity and scatter parameters were variably associated. The AUC was highest for MMoV (0.74) and lowest for CRP (0.62). Among all parameters, MNV and MMoV had the highest specificity of 85% and 80%, respectively. Conclusion: In critically ill patients with suspected sepsis, VCS parameters may help strengthen the diagnostic probability of sepsis. Future studies may explore the role of serial monitoring of VCS to track response to antimicrobial therapy.

Abstract Background: Predicting successful liberation from mechanical ventilation (MV) in critically ill patients is challenging. Brain natriuretic peptide (BNP) has been proposed to help guide decision-making for readiness to liberate from MV following a spontaneous breathing trial (SBT). Methods : We performed a systematic review and meta-analysis of randomized and prospective observational studies that measured BNP levels at the time of SBT in patients receiving MV. The primary endpoint was successful liberation from MV (absence of re-intubation or non-invasive ventilation at 48h). Statistical analyses included bi-variate and Moses-Littenberg models, and DerSimonian-Laird pooling of areas under ROC curve (AUROC). Results: A total of 731 articles were screened. Eighteen adult and 2 pediatric studies were fulfilled pre-specified eligibility. The measure of the relative variation of BNP during SBT (DBNP%) after exclusion of SBT failure by clinical criteria in adults yielded a sensitivity and specificity of 0.889 [0.831-0.929] and 0.828 [0.730-0.896] for successful liberation from MV respectively, with a pooled AUROC of 0.92 [0.88-0.97]. The pooled AUROC for any method of analysis for absolute variation of BNP (DBNP), pre-SBT BNP and post-SBT BNP were 0.89 [0.83-0.95], 0.77 [0.63-0.91], and 0.85 [0.80-0.90], respectively.Conclusion: The relative change in BNP during a SBT has potential value as an incremental tool after successful SBT to predict successful liberation from MV in adults. There is insufficient data to support the use of BNP in children or as an alternate test to clinical indices of SBT or the use of DBNP, BNP-pre and BNP-post as an alternate or incremental test.Trial registration number: PROSPERO CRD42018087474 (2018-02-06)
