Zhu B, Zhou R, Qin J, Li Y. Hierarchical Capability in Distinguishing Severities of Sepsis via Serum Lactate: A Network Meta-Analysis. Biomedicines 2024; 12:447. [PMID: 38398049 PMCID: PMC10886935 DOI: 10.3390/biomedicines12020447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 01/30/2024] [Accepted: 02/01/2024] [Indexed: 02/25/2024] Open
Abstract
Background: Blood lactate is a potentially useful biomarker to predict the mortality and severity of sepsis. The purpose of this study is to systematically review the ability of lactate to predict hierarchical sepsis clinical outcomes and distinguish sepsis, severe sepsis and septic shock. Methods: We conducted an exhaustive search of the PubMed, Embase and Cochrane Library databases for studies published before 1 October 2022. Inclusion criteria mandated the presence of case-control, cohort studies and randomized controlled trials that established the association between before-treatment blood lactate levels and the mortality of individuals with sepsis, severe sepsis or septic shock. Data was analyzed using STATA Version 16.0. Results: A total of 127 studies, encompassing 107,445 patients, were ultimately incorporated into our analysis. Meta-analysis of blood lactate levels at varying thresholds revealed a statistically significant elevation in blood lactate levels predicting mortality (OR = 1.57, 95% CI 1.48-1.65, I2 = 92.8%, p < 0.00001). Blood lactate levels were significantly higher in non-survivors compared to survivors in sepsis patients (SMD = 0.77, 95% CI 0.74-0.79, I2 = 83.7%, p = 0.000). The prognostic utility of blood lactate in sepsis mortality was validated through hierarchical summary receiver operating characteristic curve (HSROC) analysis, yielding an area under the curve (AUC) of 0.72 (95% CI 0.68-0.76), accompanied by a summary sensitivity of 0.65 (95% CI 0.59-0.7) and a summary specificity of 0.7 (95% CI 0.64-0.75). Unfortunately, the network meta-analysis could not identify any significant differences in average blood lactate values' assessments among sepsis, severe sepsis and septic shock patients. Conclusions: This meta-analysis demonstrated that high-level blood lactate was associated with a higher risk of sepsis mortality. Lactate has a relatively accurate predictive ability for the mortality risk of sepsis. However, the network analysis found that the levels of blood lactate were not effective in distinguishing between patients with sepsis, severe sepsis and septic shock.

Abstract
INTRODUCTION The dysregulated host immune response in sepsis is orchestrated by peripheral blood leukocytes. This study explored the associations of the peripheral blood leukocyte subpopulations with early clinical deterioration and mortality in sepsis. METHODS We performed a prospective observational single-center study enrolling adult subjects with sepsis within 48 h of hospital admission. Peripheral blood flow cytometry was performed for the patients at enrolment and after 5 days. The primary outcome was to explore the association between various leukocyte subpopulations at enrolment and early clinical deterioration [defined as an increase in the sequential organ failure assessment (SOFA) score between enrolment and day 5, or death before day 5]. Other pre-specified outcomes explored associations of leukocyte subpopulations at enrolment and on day 5 with in-hospital mortality. RESULTS A total of 100 patients, including 47 with septic shock were enrolled. The mean (SD) age of the patients was 53.99 (14.93) years. Among them, 26 patients had early clinical deterioration, whereas 41 died during hospitalization. There was no significant association between the leukocyte subpopulations at enrolment and early clinical deterioration on day 5. On multivariate logistic regression, a reduced percentage of CD8 + CD25+ T-cells at enrolment was associated with in-hospital mortality [odds ratio (OR), 0.82 (0.70-0.97); p-value = 0.02]. A reduced lymphocyte percentage on day 5 was associated with in-hospital mortality [OR, 0.28 (0.11-0.69); p-value = 0.01]. In a post-hoc analysis, patients with "very early" deterioration within 48 h had an increased granulocyte CD64 median fluorescent intensity (MFI) [OR, 1.07 (1.01-1.14); p-value = 0.02] and a reduced granulocyte CD16 MFI [OR, 0.97 (0.95-1.00); p-value = 0.04] at enrolment. CONCLUSIONS None of the leukocyte subpopulations showed an association with early clinical deterioration at day 5. Impaired lymphocyte activation and lymphocytopenia indicative of adaptive immune dysfunction may be associated with in-hospital mortality.

Abstract
Sepsis is one of the most challenging health conditions worldwide, with relatively high incidence and mortality rates. It is shown that preventing sepsis is the key to avoid potentially irreversible organ dysfunction. However, data-driven early identification of sepsis is challenging as sepsis shares signs and symptoms with other health conditions. This paper adopts a temporal pattern mining approach to identify frequent temporal and evolving patterns of physiological and biological biomarkers in sepsis patients. We show that using these frequent patterns as features for classifying sepsis and non-sepsis patients can improve the prediction accuracy and performance up to 7%. Most of the temporal modeling approaches adopted in the sepsis literature are based on deep learning methods. Although these approaches produce high accuracy, they generally have limited model explainability and interpretability. Using the adopted methods in this study, we could identify the most important features contributing to the patients' sepsis incidence, such as fluctuations in platelet, lactate, and creatinine, or evolution of patterns including renal and metabolic organ systems, and consequently, enhance the findings' clinical interpretability.

Abstract
CONTEXT Currently, little is known about the timely application of clinical screening tools and blood sampling for decision-making in the management of patients with suspected sepsis in the accident and emergency units of hospitals in Nigeria. AIM The aim of the study was to ascertain the association between the time taken for the conduct of serum lactate and blood culture investigations following a clinical suspicion of sepsis, and the mortality of patients admitted to a Nigerian tertiary hospital. METHODS Over a 6-month period (November 2021 to April 2022), 119 patients hospitalised for sepsis or septic shock at the Lagos University Teaching Hospital were followed until discharge or death. The proportion of patients whose serum lactate, serum procalcitonin and blood culture samples was taken was also determined. Predictors of mortality were determined using bivariate analysis and logistic regression. Kaplan-Meier plots were used to predict survival using sepsis diagnostic criteria. RESULTS Eighty (67%) of 119 sepsis patients met systemic inflammatory response syndrome or quick sequential (sepsis-related) organ failure assessment criteria. Only 3 (2.5%) patients had blood cultures and serum procalcitonin and 0 (0%) had serum lactate tests. Forty-one (34.5%) patients died, but clinical and laboratory procedures for sepsis management were not linked to death. A shorter hospital stay increased the death risk (χ2 = 14.83, P = 0.002). CONCLUSION This study revealed low compliance with sepsis care guidelines and no impact of timely clinical and laboratory procedures on sepsis mortalities. Further study is needed to explore patient care models that can improve the objective assessment and treatment of sepsis patients in emergency departments of busy tertiary hospitals.

Abstract
Abstract
Background
The majority of children who die of sepsis suffer from refractory shock and/or multiple organ dysfunction syndrome, with many deaths occurring within the initial 48–72 h of treatment.
Methods
A retrospective observational study of deceased patients due to severe sepsis over 5 years, from the 1st of August 2015 to the end of July 2020, that were admitted in a pediatric intensive care unit.
Results
Over 5-year duration of the study, the trend of cases with severe sepsis increased from 26.4% in 2015 to 40.7% in 2020. Meanwhile, the trend of mortality among this category of patients dropped from 66.7% in 2015 to 33.9% in 2020. From the studied 163 deceased patients, results showed predominance of Klebsiella pneumoniae of the extended resistance pattern in bronchoalveolar lavage and blood cultures, and it came second to Candida in urine cultures. Pandrug-resistant organism was recorded in 8.59% (n = 14 patients). Patients with bacteremia, acidosis, high pediatric index of mortality (PIM-2), and pediatric logistic organ dysfunction (PELOD) scores were statistically related to early fatality fate.
Conclusion
High mortality was associated with the increasing spread of resistant organisms especially Klebsiella pneumoniae. Patients with bacteremia, acidosis, and high PIM-2 and PELOD scores probably will need immediate, vigorous, and intense care in order to save their lives.

Abstract
Background Limited research has explored early mortality among patients presenting with septic shock. The objective of this study was to determine the incidence and factors associated with early death following emergency department (ED) presentation of septic shock. Methods A prospective registry of patients enrolled in an ED septic shock clinical pathway was used to identify patients. Patients were compared across demographic, comorbid, clinical, and treatment variables by death within 72 hours of ED presentation. Results Among the sample of 2,414 patients, overall hospital mortality was 20.6%. Among patients who died in the hospital, mean and median time from ED presentation to death were 4.96 days and 2.28 days, respectively. Death at 24, 48, and 72 hours occurred in 5.5%, 9.5%, and 11.5% of patients, respectively. Multivariate regression analysis demonstrated that the following factors were independently associated with early mortality: age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.03–1.05), malignancy (OR, 1.53; 95% CI, 1.11–2.11), pneumonia (OR, 1.39; 95% CI, 1.02–1.88), urinary tract infection (OR, 0.63; 95% CI, 0.44–0.89), first shock index (OR, 1.85; 95% CI, 1.27–2.70), early vasopressor use (OR, 2.16; 95% CI, 1.60–2.92), initial international normalized ratio (OR, 1.14; 95% CI, 1.07–1.27), initial albumin (OR, 0.55; 95% CI, 0.44–0.69), and first serum lactate (OR, 1.21; 95% CI, 1.16–1.26). Conclusions Adult septic shock patients experience a high rate of early mortality within 72 hours of ED arrival. Recognizable clinical factors may aid the identification of patients at risk of early death.

Abstract
Introduction Sepsis is the dysregulated response of the body to the infection. Obstetric sepsis carries significantly greater morbidity and mortality as the condition is also augmented by the physiological adaptation of body during pregnancy. We conducted this study to determine the various epidemiological and clinical determinants of severity of sepsis which can help in prediction of survival in case of obstetric sepsis. Materials and Methods This retrospective study was conducted in a tertiary care center and all cases admitted with the diagnosis of obstetric sepsis as per the defined criteria between January 1, 2016 and December 31, 2020 were included in the study. Patients were evaluated for their clinical presentation, SOFA score, biochemical and microbiological parameters and the treatment given during their course of stay. Variables were compared among survivor and non-survivor group using appropriate statistical tests. Parameters which have significant association were further taken for binary logistic regression analysis. Result A total 46 patients of obstetric sepsis were admitted under defined criteria. Twelve out of 46 patients did not survive (26.09%). On statistical analysis, mean SOFA score (p = 0.005) as well as patients with SOFA score > 6 (p = 0.029), presence of multi organ failure (0.04) and septic shock (p = 0.012) were found to be significantly associated with mortality. Conclusion The study suggests that these determinants of survival should always be evaluated while catering to a patient of obstetric sepsis in order to guide the treatment, prognostication and improving outcome of the patients.

Assessment of Metabolic Dysfunction in Sepsis in a Retrospective Single-Centre Cohort. Crit Care Res Pract 2021; 2021:3045454.

Abstract
Objective Our primary aim was to assess selected metabolic dysfunction parameters, both independently and as a complement to the SOFA score, as predictors of short-term mortality in patients with infection admitted to the intensive care unit (ICU). Methods We retrospectively enrolled all consecutive adult patients admitted to the eight ICUs of Lille University Hospital, between January 2015 and September 2016, with suspected or confirmed infection. We selected seven routinely measured biological and clinical parameters of metabolic dysfunction (maximal arterial lactatemia, minimal and maximal temperature, minimal and maximal glycaemia, cholesterolemia, and triglyceridemia), in addition to age and the Charlson's comorbidity score. All parameters and SOFA scores were recorded within 24 h of admission. Results We included 956 patients with infection, among which 295 (30.9%) died within 90 days. Among the seven metabolic parameters investigated, only maximal lactatemia was associated with higher risk of 90-day hospital mortality in SOFA-adjusted analyses (SOFA-adjusted OR, 1.17; 95%CI, 1.10 to 1.25; p < 0.001). Age and the Charlson's comorbidity score were also statistically associated with a poor prognosis in SOFA-adjusted analyses. We were thus able to develop a metabolic failure, age, and comorbidity assessment (MACA) score based on scales of lactatemia, age, and the Charlson's score, intended for use in combination with the SOFA score. Conclusions The maximal lactatemia level within 24 h of ICU admission is the best predictor of short-term mortality among seven measures of metabolic dysfunction. Our combined "SOFA + MACA" score could facilitate early detection of patients likely to develop severe infections. Its accuracy requires further evaluation.

Abstract
OBJECTIVES Traumatic brain injury is a leading cause of death and disability in the United States. While the impact of early multiple organ dysfunction syndrome has been studied in many critical care paradigms, the clinical impact of early multiple organ dysfunction syndrome in traumatic brain injury is poorly understood. We examined the incidence and impact of early multiple organ dysfunction syndrome on clinical, functional, and disability outcomes over the year following traumatic brain injury. DESIGN Retrospective cohort study. SETTING Patients enrolled in the Transforming Clinical Research and Knowledge in Traumatic Brain Injury study, an 18-center prospective cohort study of traumatic brain injury patients evaluated in participating level 1 trauma centers. SUBJECTS Adult (age > 17 yr) patients with moderate-severe traumatic brain injury (Glasgow Coma Scale < 13). We excluded patients with major extracranial injury (Abbreviated Injury Scale score ≥ 3). INTERVENTIONS Development of early multiple organ dysfunction syndrome, defined as a maximum modified Sequential Organ Failure Assessment score greater than 7 during the initial 72 hours following admission. MEASUREMENTS AND MAIN RESULTS The main outcomes were: hospital mortality, length of stay, 6-month functional and disability domains (Glasgow Outcome Scale-Extended and Disability Rating Scale), and 1-year mortality. Secondary outcomes included: ICU length of stay, 3-month Glasgow Outcome Scale-Extended, 3-month Disability Rating Scale, 1-year Glasgow Outcome Scale-Extended, and 1-year Disability Rating Scale. We examined 373 subjects with moderate-severe traumatic brain injury. The mean (sd) Glasgow Coma Scale in the emergency department was 5.8 (3.2), with 280 subjects (75%) classified as severe traumatic brain injury (Glasgow Coma Scale 3-8). Among subjects with moderate-severe traumatic brain injury, 252 (68%) developed early multiple organ dysfunction syndrome. Subjects that developed early multiple organ dysfunction syndrome had a 75% decreased odds of a favorable outcome (Glasgow Outcome Scale-Extended 5-8) at 6 months (adjusted odds ratio, 0.25; 95% CI, 0.12-0.51) and increased disability (higher Disability Rating Scale score) at 6 months (adjusted mean difference, 2.04; 95% CI, 0.92-3.17). Subjects that developed early multiple organ dysfunction syndrome experienced an increased hospital length of stay (adjusted mean difference, 11.4 d; 95% CI, 7.1-15.8), with a nonsignificantly decreased survival to hospital discharge (odds ratio, 0.47; 95% CI, 0.18-1.2). CONCLUSIONS Early multiple organ dysfunction following moderate-severe traumatic brain injury is common and independently impacts multiple domains (mortality, function, and disability) over the year following injury. Further research is necessary to understand underlying mechanisms, improve early recognition, and optimize management strategies.

Abstract
Sepsis is a devastating multi-stage health condition with a high mortality rate. Its complexity, prevalence, and dependency of its outcomes on early detection have attracted substantial attention from data science and machine learning communities. Previous studies rely on individual cellular and physiological responses representing organ system failures to predict health outcomes or the onset of different sepsis stages. However, it is known that organ systems' failures and dynamics are not independent events. In this study, we identify the dependency patterns of significant proximate sepsis-related failures of cellular and physiological responses using data from 12,223 adult patients hospitalized between July 2013 and December 2015. The results show that proximate failures of cellular and physiological responses create better feature sets for outcome prediction than individual responses. Our findings reveal the few significant proximate failures that play the major roles in predicting patients' outcomes. This study's results can be simply translated into clinical practices and inform the prediction and improvement of patients' conditions and outcomes.

Abstract
Advances in sepsis resuscitation have significantly improved shock control; however, many patients still die after septic shock reversal. We conducted a retrospective review to examine in-hospital death in whom shock was reversed and vasopressor was discontinued for 72 hours or longer. Factors independently associated with death were determined. Medical records of septic shock survivors from the medical intensive care unit of the Department of Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, during January 2012-January 2019 were analyzed. A total of 350 septic shock patients were enrolled. Of these, 280 survived initial resuscitation. Eighty of 280 patients died, 45 died by 28 days (16.1%), and 35 (12.5%) died thereafter during their hospital stay. Multi-organ failure and hospital-acquired pneumonia (HAP) were the leading causes of death, followed by other infection and noninfectious complication. Although the death group had more laboratory derangement and required more organ support, there were four factors associated with mortality from multivariate analysis. Hospital-acquired pneumonia was the leading factor, followed by sequential organ failure assessment score and serum albumin at 72 hours after discontinuation of vasopressors, and total intravenous fluid during 72 hours after discontinuation of vasopressors. In-hospital mortality after hemodynamic restoration in patients with septic shock was substantial. Causes and contributing factors were identified. Measures to mitigate these risks would be beneficial for rendering more favorable patient outcomes.

Abstract
Improving understanding of the prognostic factors associated with death resulting from sepsis in obstetric patients is essential to allow management to be optimized. This retrospective cohort study aimed to determine the risk factors for death in patients with sepsis admitted to the obstetric intensive care unit of a tertiary teaching hospital in northeastern Brazil between April 2012 and April 2016.The clinical, obstetric, and laboratory data of the sepsis patients, as well as data on their final outcome, were collected. A significance level of 5% was adopted. Risk factors for death in patients with sepsis were evaluated in a multivariate analysis.During the period analyzed, 155 patients with sepsis were identified and included in the study, representing 5.2% of all obstetric intensive care unit (ICU) admissions. Of these, 14.2% (n = 22) died. The risk factors for death were septic shock at the time of hospitalization (relative risk [RR] = 3.45; 95% confidence interval [CI]: 1.64-7.25), need for vasopressors during hospitalization (RR = 17.32; 95% CI: 4.20-71.36), lactate levels >2 mmol/L at the time of diagnosis (RR = 4.60; 95% CI: 1.05-20.07), and sequential organ failure assessment score >2 at the time of diagnosis (RR = 5.97; 95% CI: 1.82-19.94). Following multiple logistic regression analysis, only the need for vasopressors during hospitalization remained as a risk factor associated with death (odds ratio [OR] = 26.38; 95% CI: 5.87-118.51).The need for vasopressors during hospitalization is associated with death in obstetric patients with sepsis.

Abstract
Objective To investigate the prevalence, risk factors and mortality rate for acute respiratory distress syndrome (ARDS) in Chinese patients with sepsis. Methods This prospective study was based on data from consecutive patients with sepsis who attended Cangzhou Central Hospital between January 2017 and May 2019 and who developed ARDS. Multivariate logistic regression was used to identify risk factors associated independently with ARDS development. Results Of the 150 sepsis patients, 41 (27%) developed ARDS. Smoking history, presence of chronic obstructive pulmonary disease (COPD), the C-reactive protein (CRP) levels and the Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were associated with developing ARDS. Moreover, combination of the four factors had an even better predictive value for risk of ARDS than each factor alone. 28-day mortality was higher in sepsis patients with ARDS compared with those without ARDS. Conclusions In Chinese patients with sepsis, ARDS is relatively common and is associated with increased mortality. Smoking, COPD, CRP levels and APACHE II scores may be useful in predicting sepsis patients who may be at risk of developing ARDS.

Abstract
BACKGROUND Sepsis is a global health care problem with a high mortality. Early death seems common; however, data are sparse. The objective of the present study was to report causes and influencing factors of early death in sepsis and septic shock. METHODS All septic ICU patients were included from 2012 to 2017. Early death was predefined as occurring within 48 h. Causes and factors leading up to death were reported by a panel of four intensivists, independently reviewing the medical files. Following factors were assessed: (1) delay in ICU admission; (2) futile ICU treatment; (3) missed diagnosis or inadequate treatment on the ICU. Fleiss kappa was used to assess inter-observer agreement. RESULTS 1107 septic patients (APACHE II score 25 ± 8) were included. 344 patients died of which 97 (28%) within 48 h. In 33% an autopsy was performed. Primary causes of early death were multiple organ failure, mesenteric ischaemia and death after cardio-pulmonary resuscitation (CPR). Delay in ICU admission was scored in 32% of early deaths with slight agreement (κ = 0.180), futile ICU treatment in 29% with moderate agreement (κ = 0.415) and missed diagnosis or treatment in 7% of cases with slight agreement (κ = 0.122). CONCLUSIONS Early death after ICU admission in sepsis is common and primarily caused by multiple organ failure, mesenteric ischaemia and death after unsuccessful CPR. Influencing factors were delay in ICU admission and futile ICU admission. Fleiss kappa indicates substantial variability in clinical judgement between intensivists, strengthening the necessity for shared decision making.

Abstract
This study examines the relationship between serial serum lactate levels and in-hospital mortality in an adult cohort of emergency department patients with severe sepsis or septic shock. Of the 164 patients in the cohort, 130 also got three-hour lactate in addition to the initial one. The median initial lactate was 3.01 (interquartile range [IQR]: 1.71-4.62). The median repeat lactate was 2.58 (IQR: 1.4-3.9). The in-hospital death rate was 23% for men and 29% for women. The delta lactate was significantly higher in women (P=0.0070), driven by a lower initial lactate (P=0.0277). In a multivariate regression model controlled for age and gender, a statistically significant correlation was noted between an increase in the delta lactate and in-hospital death (P=0.0323; R2=11.3%). The results of this single-center study suggest that an increase in serum lactic acid is significantly associated with higher in-hospital death.

Abstract
BACKGROUND Sepsis is the leading cause of death in critically ill patients. Ulinastatin (UTI), a protease inhibitor, and rhubarb, used as a traditional Chinese medication, are proved to be effective in treating sepsis, but the effect of the combination therapy of these two drugs on sepsis remains unclear. This study aimed to investigate the effect of the combination treatment of UTI and rhubarb on sepsis patients. METHODS A total of 75 septic patients were randomly divided into control group, UTI group, Rhubarb group, and UTI plus Rhubarb group. Clinical data and score of Acute Physiology and Chronic Health Evaluation II (APACHE II) were collected; lymphocyte subtypes in the peripheral blood were analyzed before and after the 5-day treatment in the Intensive Care Unit. RESULTS All the therapeutic interventions (UTI alone, rhubarb alone, or UTI plus rhubarb) significantly reduced the levels of C-Reactive protein, white blood cell density, lactic acid, and APACH II scores, and elevated the levels of CD4/CD8, but only UTI plus rhubarb treatment obviously decreased the level of procalcitonin. CONCLUSION This study suggested that the combination of UTI and rhubarb may be a promising therapeutic scheme to ameliorate sepsis.

Abstract
BACKGROUND There is little published data investigating non-invasive cardiac output monitoring in the emergency department (ED). We assess here the accuracy of five non-invasive methods in detecting fluid responsiveness in the ED: (1) common carotid artery blood flow, (2) suprasternal aortic Doppler, (3) bioreactance, (4) plethysmography with digital vascular unloading method, and (5) inferior vena cava collapsibility index. Left ventricular outflow tract echocardiography derived velocity time integral is the reference standard. This follows an assessment of feasibility and repeatability of these methods in the same cohort of ED patients. METHODS This is a prospective observational study of non-invasive methods for assessing fluid responsiveness in the ED. Participants were non-ventilated ED adult patients requiring intravenous fluid resuscitation. Sensitivity and specificity of each method in determining the fluid responsiveness status of participants is determined in comparison to the reference standard. RESULTS Thirty-three patient data sets were included for analysis. The specificity and sensitivity to detect fluid responders was 46.2 and 45% for common carotid artery blood flow (CCABF), 61.5 and 63.2% for suprasternal artery Doppler (SSAD), 46.2 and 50% for bioreactance, 50 and 41.2% for plethysmography vascular unloading technique (PVUT), and 63.6 and 47.4% for inferior vena cava collapsibility index (IVCCI), respectively. Analysis of agreement with Cohen's Kappa - 0.08 for CCABF, 0.24 for SSAD, - 0.04 for bioreactance, - 0.08 for PVUT, and 0.1 for IVCCI. CONCLUSION In this study, non-invasive methods were not found to reliably identify fluid responders. Non-invasive methods of identifying fluid responders are likely to play a key role in improving patient outcome in the ED in fluid depleted states such as sepsis. These results have implications for future studies assessing the accuracy of such methods.

Abstract
PURPOSE Albumin-based fluid therapy in septic shock is a matter of debate and criticism. The aim of this study was to assess the cost-effectiveness of albumin therapy in patients with septic shock. METHODS A retrospective cohort study was conducted in Imam Khomeini, Sina, and Shariati hospitals on patients with septic shock admitted to intensive care units from March 31, 2016 to September 22, 2017. Data sources were the health information system database and patient medical records. The patients with potential septic shock were identified based on norepinephrine use. Septic shock was confirmed after medical record review based on systemic inflammatory response syndrome criteria, antibiotic use, and fluid therapy. Patients who received albumin in the fluid therapy were compared with patients treated without albumin. The 28-day mortality, life-year gain, and cost-effectiveness were evaluated. FINDINGS The addition of albumin had no significant increase in life-year gain (mean difference = 0.67; 95% CI, -2.25 to 3.58). However, the addition of albumin increased the total cost of treatment by US $3846.07 (95% CI, US $2093.46-US $5598.98). The incremental cost-effectiveness ratio calculated based on the mean life-years gained was US$5740.40 per a life-year gained. The net monetary benefit was negative (-355.4; 95% CI, -15,387.61 to 14,676.81), and the probability that the addition of albumin will be cost-effective at a gross domestic product per capita was 40.0%. IMPLICATIONS Albumin-based fluid therapy does not improve the 28-day mortality of patients with septic shock. The addition of albumin in the fluid therapy of patients with septic shock was not cost-effective. Both the observational and retrospective nature of the study was expected to introduce bias. We recommend a cost-effectiveness analysis combined with clinical trials to settle the debate once and for all.

Abstract
IMPORTANCE Experimental data suggest that intravenous vitamin C may attenuate inflammation and vascular injury associated with sepsis and acute respiratory distress syndrome (ARDS). OBJECTIVE To determine the effect of intravenous vitamin C infusion on organ failure scores and biological markers of inflammation and vascular injury in patients with sepsis and ARDS. DESIGN, SETTING, AND PARTICIPANTS The CITRIS-ALI trial was a randomized, double-blind, placebo-controlled, multicenter trial conducted in 7 medical intensive care units in the United States, enrolling patients (N = 167) with sepsis and ARDS present for less than 24 hours. The study was conducted from September 2014 to November 2017, and final follow-up was January 2018. INTERVENTIONS Patients were randomly assigned to receive intravenous infusion of vitamin C (50 mg/kg in dextrose 5% in water, n = 84) or placebo (dextrose 5% in water only, n = 83) every 6 hours for 96 hours. MAIN OUTCOMES AND MEASURES The primary outcomes were change in organ failure as assessed by a modified Sequential Organ Failure Assessment score (range, 0-20, with higher scores indicating more dysfunction) from baseline to 96 hours, and plasma biomarkers of inflammation (C-reactive protein levels) and vascular injury (thrombomodulin levels) measured at 0, 48, 96, and 168 hours. RESULTS Among 167 randomized patients (mean [SD] age, 54.8 years [16.7]; 90 men [54%]), 103 (62%) completed the study to day 60. There were no significant differences between the vitamin C and placebo groups in the primary end points of change in mean modified Sequential Organ Failure Assessment score from baseline to 96 hours (from 9.8 to 6.8 in the vitamin C group [3 points] and from 10.3 to 6.8 in the placebo group [3.5 points]; difference, -0.10; 95% CI, -1.23 to 1.03; P = .86) or in C-reactive protein levels (54.1 vs 46.1 μg/mL; difference, 7.94 μg/mL; 95% CI, -8.2 to 24.11; P = .33) and thrombomodulin levels (14.5 vs 13.8 ng/mL; difference, 0.69 ng/mL; 95% CI, -2.8 to 4.2; P = .70) at 168 hours. CONCLUSIONS AND RELEVANCE In this preliminary study of patients with sepsis and ARDS, a 96-hour infusion of vitamin C compared with placebo did not significantly improve organ dysfunction scores or alter markers of inflammation and vascular injury. Further research is needed to evaluate the potential role of vitamin C for other outcomes in sepsis and ARDS. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02106975.

Abstract
INTRODUCTION The "quick Sequential Organ Failure Assessment" (qSOFA) score is a bedside risk-stratification tool to predict the likelihood of organ dysfunction. This study evaluated the qSOFA score as a prognostic factor for 30-day mortality in emergency department (ED) patients with sepsis identified by the Systemic Inflammatory Response Syndrome (SIRS) criteria. METHODS A historical cohort study was conducted reviewing patients admitted to a single-center ED from November 1, 2013, to October 31, 2014. All patients with suspected or proven infections who fulfilled two or more SIRS criteria were included. Data of SIRS, qSOFA and baseline clinical data were obtained from triage forms and patient records. RESULTS A total of 434 patients with sepsis of any severity were included. A total of 73 (16.8%) had a qSOFA score of ≥2 and were more frequently transferred to the intensive care unit (ICU) (26.0 vs. 6.7%; 95% confidence interval (CI) of the difference 8.9-29.7%) and had increased 30-day mortality (32.9 vs. 9.1%, 95% CI of the difference 12.6-35.0%) compared to patients with a qSOFA score of <2. In an adjusted logistic regression model, a qSOFA score of ≥2 was independently associated with 30-day mortality (odds ratio 4.83; 95% CI 2.11-11.02). CONCLUSION Almost one third of the patients with a qSOFA score of ≥2 had died within 30 days and a qSOFA score of ≥2 was independently associated with mortality. This study indicated that qSOFA score of at least two could provide useful prognostic information for septic patients defined by the SIRS criteria.

Abstract
OBJECTIVES Early organ dysfunction in sepsis confers a high risk of in-hospital mortality, but the relative contribution of specific types of organ failure to overall mortality is unclear. The objective of this study was to assess the predictive ability of individual types of organ failure to in-hospital mortality or prolonged intensive care. METHODS Retrospective cohort study of adult emergency department patients with sepsis from October 1, 2013, to November 10, 2015. Multivariable regression was used to assess the odds ratios of individual organ failure types for the outcomes of in-hospital death (primary) and in-hospital death or ICU stay ≥ 3 days (secondary). RESULTS Of 2796 patients, 283 (10%) experienced in-hospital mortality, and 748 (27%) experienced in-hospital mortality or an ICU stay ≥ 3 days. The following components of Sequential Organ Failure Assessment (SOFA) score were most predictive of in-hospital mortality (descending order): coagulation (odds ratio [OR]: 1.60, 95% confidence interval [CI]: 1.32-1.93), hepatic (1.58, 95% CI: 1.32-1.90), respiratory (OR: 1.33, 95% CI: 1.21-1.47), neurologic (OR: 1.20, 95% CI: 1.07-1.35), renal (OR: 1.14, 95% CI: 1.02-1.27), and cardiovascular (OR: 1.13, 95% CI: 1.01-1.25). For mortality or ICU stay ≥3 days, the most predictive SOFA components were respiratory (OR: 1.97, 95% CI: 1.79-2.16), neurologic (OR: 1.72, 95% CI: 1.54-1.92), cardiovascular (OR: 1.38, 95% CI: 1.23-1.54), coagulation (OR: 1.31, 95% CI: 1.10-1.55), and renal (OR: 1.19, 95% CI: 1.08-1.30) while hepatic SOFA (OR: 1.16, 95% CI: 0.98-1.37) did not reach statistical significance (P = .092). CONCLUSION In this retrospective study, SOFA score components demonstrated varying predictive abilities for mortality in sepsis. Elevated coagulation or hepatic SOFA scores were most predictive of in-hospital death, while an elevated respiratory SOFA was most predictive of death or ICU stay >3 days.

Metabolic profiles in community-acquired pneumonia: developing assessment tools for disease severity. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:130. [PMID: 29759075 PMCID: PMC5952829 DOI: 10.1186/s13054-018-2049-2] [Citation(s) in RCA: 39] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Accepted: 04/23/2018] [Indexed: 01/11/2023]
Abstract
Background This study aimed to determine whether community-acquired pneumonia (CAP) had a metabolic profile and whether this profile can be used for disease severity assessment. Methods A total of 175 individuals including 119 CAP patients and 56 controls were enrolled and divided into two cohorts. Serum samples from a discovery cohort (n = 102, including 38 non-severe CAP, 30 severe CAP, and 34 age and sex-matched controls) were determined by untargeted ultra-high-performance liquid chromatography with tandem mass spectrometry (LC-MS/MS)-based metabolomics. Selected differential metabolites between CAP patients versus controls, and between the severe CAP group versus non-severe CAP group, were confirmed by targeted mass spectrometry assays in a validation cohort (n = 73, including 32 non-severe CAP, 19 severe CAP and 22 controls). Pearson’s correlation analysis was performed to assess relationships between the identified metabolites and clinical severity of CAP. The area under the curve (AUC), sensitivity and specificity of the metabolites for predicting the severity of CAP were also investigated. Results The metabolic signature was markedly different between CAP patients and controls. Fifteen metabolites were found to be significantly dysregulated in CAP patients, which were mainly mapped to the metabolic pathways of sphingolipid, arginine, pyruvate and inositol phosphate. The alternation trends of five metabolites among the three groups including sphinganine, p-Cresol sulfate, dehydroepiandrosterone sulfate (DHEA-S), lactate and l-arginine in the validation cohort were consistent with those in the discovery cohort. Significantly lower concentrations of sphinganine, p-Cresol sulfate and DHEA-S were observed in CAP patients than in controls (p < 0.05). Serum lactate and sphinganine levels were positively correlated with confusion, urea level, respiratory rate, blood pressure, and age > 65 years (CURB-65), pneumonia severity index (PSI) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, while DHEA-S inversely correlated with the three scoring systems. Combining lactate, sphinganine and DHEA-S as a metabolite panel for discriminating severe CAP from non-severe CAP exhibited a better AUC of 0.911 (95% confidence interval 0.825–0.998) than CURB-65, PSI and APACHE II scores. Conclusions This study demonstrates that serum metabolomics approaches based on the LC-MS/MS platform can be applied as a tool to reveal metabolic changes during CAP and establish a metabolite signature related to disease severity.
