Abstract
INTRODUCTION Therapeutic plasma exchange (TPE) is used in a wide spectrum of diseases in critically ill pediatric patients. We aim to review the indications, complications, safety, and outcomes of critically ill children who received TPE. METHODS All of the TPE procedures performed in a pediatric intensive care unit providing tertiary care during 19 years (January 2013-January 2023) were evaluated retrospectively. A total of 154 patients underwent 486 TPE sessions. RESULTS Median age was 6 years (2-12.5) and 35 children had a body weight of <10 kg (22.7%). Number of organ failure was 4 (2-6). Liver diseases were the most common indication for TPE (31.2%) followed by sepsis with multiorgan dysfunction syndrome (27.3%). Overall survival rate was 72.7%. The highest mortality was observed in hemophagocytic lymphohistiocytosis group. Non-survivors had significantly higher number of organ failure (p < 0.001), higher PRISM score (p < 0.001), and higher PELOD score on admission (p < 0.001). Adverse events were observed in 68 (13.9%) sessions. Hypotension (7.8%) and hypocalcemia (5.1%) were the most frequent adverse events. CONCLUSION TPE is safe for critically ill pediatric patients with experienced staff. Survival rate may vary depending on the underlying disease. Survival decreases with the increase in the number of failed organs.

Thromb J 2024; 22:67.

Abstract
Thrombocytopenia frequently occurs in patients with sepsis. Disseminated intravascular coagulation (DIC) may be a possible cause of thrombocytopenia owing to its high prevalence and association with poor outcomes; however, it is important to keep the presence of other diseases in mind in sepsis practice. Thrombotic microangiopathy (TMA), which is characterized by thrombotic thrombocytopenic purpura, Shiga toxin-producing Escherichia coli hemolytic uremic syndrome (HUS), and complement-mediated HUS, is characterized by thrombocytopenia, microangiopathic hemolytic anemia, and organ damage. TMA has become widely recognized in recent years because of the development of specific treatments. Previous studies have reported a remarkably lower prevalence of TMA than DIC; however, its epidemiology is not well defined, and there may be cases in which TMA is not correctly diagnosed, resulting in poor outcomes. Therefore, it is important to differentiate DIC from TMA. Nevertheless, differentiating between DIC and TMA remains a challenge as indicated by previous reports that most patients with TMA can be diagnosed as DIC using the universal coagulation scoring system. Several algorithms to differentiate sepsis-related DIC from TMA have been suggested, contributing to improving the care of septic patients with thrombocytopenia; however, it may be difficult to apply these algorithms to patients with coexisting DIC and TMA, which has recently been reported. This review describes the disease characteristics, including epidemiology, pathophysiology, and treatment, of DIC, TMA, and other diseases with thrombocytopenia and proposes a novel practical approach flow, which is characterized by the initiation of the diagnosis of TMA in parallel with the diagnosis of DIC. This practical flow also refers to the longitudinal diagnosis and treatment flow with TMA in mind and real clinical timeframes. In conclusion, we aim to widely disseminate the results of this review that emphasize the importance of incorporating consideration of TMA in the management of septic DIC. We anticipate that this practical new approach for the diagnostic and treatment flow will lead to the appropriate diagnosis and treatment of complex cases, improve patient outcomes, and generate new epidemiological evidence regarding TMA.

Abstract
BACKGROUND Therapeutic plasma exchange (TPE) has been used as a primary or supportive treatment in critical paediatric patients during the clinical course of many diseases. OBJECTIVES The objective of this study was to characterise the indications, complications, and outcomes of critically ill children who received TPE in a tertiary referral paediatric intensive care unit (PICU). METHODS This retrospective observational study was conducted in a tertiary referral 13-bed PICU of a university hospital. Critically ill children, who received at least one TPE procedure, were retrospectively included in the study. TPE was utilised by the same paediatric intensivist in accordance with the American Society for Apheresis (ASFA) guideline between January 2005 and December 2022. The procedures were analysed in terms of technical aspects and complications. Multivariable logistic regression analysis was performed to identify independent risk factors for mortality. RESULTS In total, 1528 TPE sessions were performed on a total of 328 children. The overall TPE utility rate was 25 per 1000 PICU admissions. Primary indications for TPE were sepsis, neurological autoimmune, haematological diseases, acute liver failure, drug overdose, and autoimmune rheumatological disorders in 109 (33.2%), 90 (27.4%), 49 (14.9%), 43 (13.1%), 12 (3.7%), and 10 (3%) of patients, respectively. The distribution of TPE indications according to ASFA categories was as follows: 37 patients (11.3%) were in category I, 44 patients (13.4%) were in category II, and 211 (64.3%) were in category III. Complications were observed in 18.7% of sessions, and the most common complications were haemodynamic (10.8%) and circuit-/catheter-related (7.6%) complications. The mortality rate was 28.4% in the study. Moreover, both Pediatric Index of Mortality 3 score and number of organ failures were found as independent risk factors for mortality. CONCLUSIONS Our results revealed that TPE may be an effective procedure even in critically ill children in accordance with ASFA recommendations. We also showed that mortality rate increased with Pediatric Index of Mortality 3 score at admission and number of organ failures.

Abstract
INTRODUCTION The impact of therapeutic plasma exchange (TPE) on short-term mortality in adult patients with sepsis-induced organ dysfunction remains uncertain. The objective of the study is to assess the effect of adjunct TPE in this setting through a comprehensive literature review. METHODS The National Library of Medicine's Medline, Ovid (Embase), the Cochrane Library database and clinicaltrial.gov from January 01, 1966, until October 01, 2022, were searched for terms: therapeutic plasma exchange, plasmapheresis, sepsis, and septic shock. We reviewed, selected and extracted data from relevant randomized clinical trials (RCTs) and matched cohort studies (MCSs) comparing short-term mortality in critically ill adult septic patients treated with standard therapy versus those receiving adjunct TPE. Risk of bias was assessed in the RCTs using Cochrane Collaboration tool and in MCSs using ROBINS-I tool. Summary statistics, risk ratios (RRs), and confidence intervals (CIs) were calculated using random effects model. RESULTS This systematic review included 937 adult critically ill septic patients from five RCTs (n = 367) and fifteen MCSs (n = 570). Of these total, 543 received treatment with TPE in addition to standard care. The meta-analysis includes all five RCTs and only six MCSs (n = 627). The adjunct TPE treatment (n = 300) showed a significant reduction in short-term mortality (RR 0.59, 95% CI 0.47-0.74, I2 3%) compared to standard therapy alone (n = 327). The systematic review of all 20 trials revealed that adding TPE to the standard therapy of critically ill septic patients resulted in faster clinical and/or laboratory recovery. CONCLUSIONS Our comprehensive and up-to-date review demonstrates that adjunct TPE may provide potential survival benefits when compared to standard care for critically ill adult patients with sepsis-induced organ dysfunction. While results of this meta-analysis are encouraging, large well-designed randomized trials are required to identify the optimal patient population and TPE procedure characteristics prior to widespread adoption into practice.

Abstract
Sepsis is a potentially lethal condition that occurs when the body's response to infection damages tissue and organs. The production of inflammatory mediators typically assists in defending the body against infection; however, an overreaction to inflammation can cause coagulation problems, vascular endothelial damage, and organ hypoperfusion. Blood purification methods, such as plasmapheresis, can effectively remove inflammatory mediators from plasma. The purpose of this meta-analysis was to explore the efficacy of plasma exchange for sepsis treatment as noted in recent studies. The authors searched the Pubmed (Medline), Cochrane Central Register of Controlled Trials (The Cochrane Library), Embase (Ovid), and Scopus databases and included controlled clinical studies that compared plasmapheresis or plasma filtration with conventional treatment in patients with severe sepsis. The Newcastle-Ottawa Scale literature quality assessment tool was used to assess the risk of bias. The primary study outcome was all-cause mortality. The random effects model was adopted for conducting the meta-analysis. Among the 1013 records found, the study included 5 trials, all of which carried a low risk of bias. The use of plasmapheresis was associated with a longer stay in the intensive care unit (odds ratio [OR], 0.85, 95% confidence interval [CI], 0.39-1.32, heterogeneity [I2 ] = 0%), a significant reduction in all-cause mortality (OR, 0.54, 95% CI, 0.33-0.89, I2 = 70%), and reduced mortality (OR, 0.29, 95% CI, 0.13-0.67, I2 = 0%) in adults; the results for children differed from this (OR, 0.79, 95% CI, 0.36-1.72, I2 = 89%). Four trials reported no adverse events; one trial reported an adverse event related to plasma exchange, including an instance of hypotension in one patient. Plasmapheresis appeared to be an effective treatment for patients suffering from sepsis. A large number of additional randomised controlled trials are needed to confirm this finding.

Abstract
OBJECTIVES To summarize the role of therapeutic plasma exchange (TPE) in critically ill adults and children with severe sepsis. DATA COLLECTION A systematic search was performed using the following databases: Medline, EMBASE, CINAHL, and Cochrane from January 1990 till December 2022. Comparative studies of TPE in severe sepsis were selected. Adult and pediatric data were analyzed separately. DATA SYNTHESIS Eight randomized control trials and 6 observational studies (n = 50,142 patients) were included. Centrifugal TPE was the most common modality (209/280, 74.6% adults and 952/1026, 92.7% children). Every TPE study utilized different volume exchanges. Most TPE sessions (1173/1306, 89.8%) employed fresh frozen plasma (FFP) as replacement fluid and heparin as anticoagulant. Adults with severe sepsis supported with TPE using FFP had lower mortality (risk ratio, RR: 0.64 [95% confidence interval, CI: 0.49, 0.84]) compared to those who did not. In contrast, TPE was associated with increased mortality in septic children without thrombocytopenia-associated multiorgan failure (RR: 2.23, 95% CI: 1.93, 2.57). There was no difference in outcomes in patients supported with centrifugal and membrane TPE. In both populations, patients supported on TPE as a continuous regime had poorer outcome. CONCLUSION Current evidence indicates that TPE is a potential adjunct therapy in adults with severe sepsis but not in children.

Abstract
Therapeutic plasma exchange (TPE) has been shown to improve organ dysfunction and survival in patients with thrombotic microangiopathy and thrombocytopenia associated with multiple organ failure. There are no known therapies for the prevention of major adverse kidney events after continuous kidney replacement therapy (CKRT). The primary objective of this study was to evaluate the effect of TPE on the rate of adverse kidney events in children and young adults with thrombocytopenia at the time of CKRT initiation. DESIGN Retrospective cohort. SETTING Two large quaternary care pediatric hospitals. PATIENTS All patients less than or equal to 26 years old who received CKRT between 2014 and 2020. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We defined thrombocytopenia as a platelet count less than or equal to 100,000 (cell/mm3) at the time of CKRT initiation. We ascertained major adverse kidney events at 90 days (MAKE90) after CKRT initiation as the composite of death, need for kidney replacement therapy, or a greater than or equal to 25% decline in estimated glomerular filtration rate from baseline. We performed multivariable logistic regression and propensity score weighting to analyze the relationship between the use of TPE and MAKE90. After excluding patients with a diagnosis of thrombotic thrombocytopenia purpura and atypical hemolytic uremic syndrome (n = 6) and with thrombocytopenia due to a chronic illness (n = 2), 284 of 413 total patients (68.8%) had thrombocytopenia at CKRT initiation (51% female). Of the patients with thrombocytopenia, the median (interquartile range) age was 69 months (13-128 mo). MAKE90 occurred in 69.0% and 41.5% received TPE. The use of TPE was independently associated with reduced MAKE90 by multivariable analysis (odds ratio [OR], 0.35; 95% CI, 0.20-0.60) and by propensity score weighting (adjusted OR, 0.31; 95% CI, 0.16-0.59). CONCLUSIONS Thrombocytopenia is common in children and young adults at CKRT initiation and is associated with increased MAKE90. In this subset of patients, our data show benefit of TPE in reducing the rate of MAKE90.

Abstract
Shock in children is associated with significant mortality and morbidity, particularly in resource-limited settings. The principles of management include early recognition, fluid resuscitation, appropriate inotropes, antibiotic therapy in sepsis, supportive therapy for organ dysfunction, and regular hemodynamic monitoring. During the past decade, each step has undergone several changes and evolved as evidence that has been translated into recommendations and practice. There is a paradigm shift from protocolized-based care to personalized management, from liberal strategies to restrictive strategies in terms of fluids, blood transfusion, ventilation, and antibiotics, and from clinical monitoring to multimodal monitoring using bedside technologies. However, uncertainties are still prevailing in terms of the volume of fluids, use of steroids, and use of extracorporeal and newer therapies while managing shock. These changes have been summarized along with evidence in this article with the aim of adopting an evidence-based approach while managing children with shock.

Abstract
Sepsis remains among the most common causes of mortality in children with congenital heart disease (CHD). Extensive literature is available regarding managing sepsis in pediatric patients without CHD. Because the cardiovascular pathophysiology of children with CHD differs entirely from their typical peers, the available diagnosis and management recommendations for sepsis cannot be implemented directly in children with CHD. This review discusses the risk factors, etiopathogenesis, available diagnostic tools, resuscitation protocols, and anesthetic management of pediatric patients suffering from various congenital cardiac lesions. Further research should focus on establishing a standard guideline for managing children with CHD with sepsis and septic shock admitted to the intensive care unit.

Abstract
BACKGROUND Thrombotic microangiopathy-induced thrombocytopenia-associated multiple organ failure and hyperinflammatory macrophage activation syndrome are important causes of late pediatric sepsis mortality that are often missed or have delayed diagnosis. The National Institutes of General Medical Science sepsis research working group recommendations call for application of new research approaches in extant clinical data sets to improve efficiency of early trials of new sepsis therapies. Our objective is to apply machine learning approaches to derive computable 24-h sepsis phenotypes to facilitate personalized enrollment in early anti-inflammatory trials targeting these conditions. METHODS We applied consensus, k-means clustering analysis to our extant PHENOtyping sepsis-induced Multiple organ failure Study (PHENOMS) dataset of 404 children. 24-hour computable phenotypes are derived using 25 available bedside variables including C-reactive protein and ferritin. RESULTS Four computable phenotypes (PedSep-A, B, C, and D) are derived. Compared to all other phenotypes, PedSep-A patients (n = 135; 2% mortality) were younger and previously healthy, with the lowest C-reactive protein and ferritin levels, the highest lymphocyte and platelet counts, highest heart rate, and lowest creatinine (p < 0.05); PedSep-B patients (n = 102; 12% mortality) were most likely to be intubated and had the lowest Glasgow Coma Scale Score (p < 0.05); PedSep-C patients (n = 110; mortality 10%) had the highest temperature and Glasgow Coma Scale Score, least pulmonary failure, and lowest lymphocyte counts (p < 0.05); and PedSep-D patients (n = 56, 34% mortality) had the highest creatinine and number of organ failures, including renal, hepatic, and hematologic organ failure, with the lowest platelet counts (p < 0.05). PedSep-D had the highest likelihood of developing thrombocytopenia-associated multiple organ failure (Adj OR 47.51 95% CI [18.83-136.83], p < 0.0001) and macrophage activation syndrome (Adj OR 38.63 95% CI [13.26-137.75], p < 0.0001). CONCLUSIONS Four computable phenotypes are derived, with PedSep-D being optimal for enrollment in early personalized anti-inflammatory trials targeting thrombocytopenia-associated multiple organ failure and macrophage activation syndrome in pediatric sepsis. A computer tool for identification of individual patient membership ( www.pedsepsis.pitt.edu ) is provided. Reproducibility will be assessed at completion of two ongoing pediatric sepsis studies.

Abstract
OBJECTIVES Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) accounts for 1 to 10% of pancreatitis cases, and is associated with a more severe clinical course. Therapeutic plasma exchange (TPE) is a potential treatment option for quickly lowering plasma triglycerides (TG). Current ASFA guidelines define HTG-AP as a Category III disorder, indicating the role of apheresis is not firmly established. Here, we examine clinical data regarding its effectiveness on morbidity and mortality in patients with HTG-AP presenting with severely elevated plasma triglycerides (>4000 mg/dl). METHODS We retrospectively examined clinical data and outcomes from 67 consecutive episodes of HTG-AP over a 5-year period in which either medical management alone or medical management plus adjunct TPE was employed to reduce plasma triglycerides. RESULTS 16/67 admissions involved TPE, initiated at a mean of 0.7 days from the time of presentation, while 51 received medical management alone. After only one TPE procedure, the mean TG values decreased from 4103 to 1045 mg/dl (a reduction of 74.7%), and those receiving TPE reached plasma TG < 1000 mg/dl 0.99 days faster than the medical group. One patient in the TPE group died. However, when excluding patients with hospital courses complicated by multiple organ dysfunction, there was no significant difference in mortality or hospital length of stay (LOS) between the groups. CONCLUSIONS In uncomplicated cases of HTG-AP with an absence of multiorgan dysfunction, there is no significant benefit to either mortality or LOS when adding adjunct TPE to medical management, even when patients present with severely elevated levels of TG.

Abstract
AbstractSince little is known about dysregulated hyperinflammatory immunological responses causing acute severe infection and multisystem inflammatory syndrome in children associated with coronavirus disease 2019 (COVID-19), the available data on therapies for severe presentations in children are very limited. Describing experiences of severe pediatric COVID-19 presentations in more detail will help improve clinical practice.In this case report, we describe the complete clinical course of a 9-year-old girl previously diagnosed with Angelman syndrome and high-risk T cell acute lymphoblastic leukemia who had been receiving reinduction chemotherapy, presented with pneumonia and acute respiratory distress syndrome, and progressively developed hyperferritinemic multiple-organ failure, a cytokine storm, and coagulopathy associated with COVID-19. She was treated with therapeutic plasma exchange, tocilizumab, hydrocortisone, and favipiravir, but she died 7 days after her admission into our pediatric intensive care unit.The utility of therapeutic plasma exchange with other immunomodulatory therapies in severe presentations requires further trials. The spectrum of the inflammatory phenotypes associated with COVID-19 should be investigated and well defined to initiate the optimal treatment strategy on time.

Abstract
Therapeutic plasma exchange (TPE) is frequently the most common Apheresis Medicine technique used for extracorporeal therapy of a wide variety of renal, neurological, hematological, and other clinical indications. Many of these clinical indications require intensive care during critical illness. Conventional TPE uses one of two main technical methods to achieve the goal of removing known disease mediators from the plasma: using centrifugal forces to separate and remove components of blood, or a membrane filtration method that separates plasma from the cellular components of blood. The following review discusses the basic principles of TPE, the technological aspects, and relevant clinical scenarios encountered in the intensive care unit, including relevant guidelines and recommendations from the American Society for Apheresis.

Abstract
Thrombocytopenia-associated multiple organ failure is a clinical phenotype encompassing a spectrum of syndromes associated with disseminated microvascular thromboses. Autopsies performed in patients that died with thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, or disseminated intravascular coagulation reveal specific findings that can differentiate these 3 entities. Significant advancements have been made in our understanding of the pathologic mechanisms of these syndromes. Von Willebrand factor and ADAMTS-13 play a central role in thrombotic thrombocytopenic purpura. Shiga toxins and the complement pathway drive the hemolytic uremic syndrome pathology. Tissue factor activity is vital in the development of disseminated intravascular coagulation.

Abstract
OBJECTIVES Since the civil war in Syria began, millions of Syrians have left the country and been forced to migrate to other countries. Turkey is the country with the most refugees hosting 3.6 million refugees. This study aimed to compare the PIM-3 score, PELOD-2 score, PELOD-2 predicted death rate (PDR), mortality rates, demographic data, and outcomes of patients admitted to pediatric intensive care units between refugee children living in Turkey, pediatric patients brought directly from the border by the emergency services, and the general Turkish population. METHODS This was a retrospective study performed between February 2018 and February 2019 at Hatay State Hospital, very close to the Syrian border. The study included 158 patients. Patients were divided into three groups: Turkish citizens, those living in Turkey as refugees, and those brought from the border. RESULTS Of the patients, 57 were Turkish citizens, 33 were refugees, and 68 were brought from the border. For patients, the mean PIM-3 score was 25.62±27.70, the PELOD-2 score was 8.03±4.72, and PELOD2-PDR was 16.07±23.45. The median scores for PIM-3, PELOD-2, and PELOD2-PDR of patients brought from the Syrian border were higher compared with Turkish citizens and refugees. There was no significant difference between refugees and Turkish citizens. Of the patients, 27 died, with the distribution being 15% Turkish citizens, 26% refugees, and 59% brought from the border. The mortality of patients transported from the border was statistically significant (P=0.03). CONCLUSION We consider that the source of the difference between patients brought from the border and those living in Turkey may be associated with the continuing war beyond our borders and children experiencing insufficient care conditions. In conclusion, it is not just weapons that cause death in war, and children unfortunately suffer because of this situation.

Abstract
The objective of this study is to characterize clinical indications, safety and outcome with the use of TPE in critically ill children. All TPE procedures performed in a tertiary pediatric intensive care unit (PICU) during a 5-year period were retrospectively evaluated. A total of 75 patients underwent 249 sessions of TPE. Sepsis-induced multiple organ dysfunction syndrome (MODS) was the most common indication with 29.3 %. American Society for Apheresis classifications were as follows: Category I: 24 %, Category II: 16 %, Category III: 45.3 % and Category IV: 4%, while 10.7 % of the patients could not be classified. TPE was performed without any adjunct procedures in 188 sessions (75.5 %), while it was combined with continuous renal replacement therapy (CRRT) in 49 sessions (19.7 %) and with CRRT and extracorporeal membrane oxygenation (ECMO) in 12 (4.8 %) sessions. Overall survival rate was 73.3 %. The survival rate in patients requiring only TPE was 86.5 %, while the survival rates of patients who had CRRT and ECMO were 45 % and 33.3 %, respectively. Complications associated with the procedure occurred in 48 (19.2 %) TPE sessions. The lowest survival rate (31.9 %) was in patients with sepsis-induced MODS. Finally, we also found significantly higher organ failure rate, mechanical ventilation requirement, and PRISM III score at PICU admission in non-survivors. Our experience indicates that TPE can be performed relatively safely in critically ill children with appropriate treatment indications. Survival rate may vary depending on the underlying disease; however, it must be noted that survival rate is very high in children requiring TPE only.

Abstract
OBJECTIVES To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction. DESIGN A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process. METHODS The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, "in our practice" statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate. RESULTS The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 49 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, "in our practice" statements were provided. In addition, 52 research priorities were identified. CONCLUSIONS A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

Abstract
OBJECTIVES To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction. DESIGN A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process. METHODS The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, "in our practice" statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate. RESULTS The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 52 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, "in our practice" statements were provided. In addition, 49 research priorities were identified. CONCLUSIONS A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

Abstract
OBJECTIVES Ongoing adult sepsis clinical trials are assessing therapies that target three inflammation phenotypes including 1) immunoparalysis associated, 2) thrombotic microangiopathy driven thrombocytopenia associated, and 3) sequential liver failure associated multiple organ failure. These three phenotypes have not been assessed in the pediatric multicenter setting. We tested the hypothesis that these phenotypes are associated with increased macrophage activation syndrome and mortality in pediatric sepsis. DESIGN Prospective severe sepsis cohort study comparing children with multiple organ failure and any of these phenotypes to children with multiple organ failure without these phenotypes and children with single organ failure. SETTING Nine PICUs in the Eunice Kennedy Shriver National Institutes of Child Health and Human Development Collaborative Pediatric Critical Care Research Network. PATIENTS Children with severe sepsis and indwelling arterial or central venous catheters. INTERVENTIONS Clinical data collection and twice weekly blood sampling until PICU day 28 or discharge. MEASUREMENTS AND MAIN RESULTS Of 401 severe sepsis cases enrolled, 112 (28%) developed single organ failure (0% macrophage activation syndrome 0/112; < 1% mortality 1/112), whereas 289 (72%) developed multiple organ failure (9% macrophage activation syndrome 24/289; 15% mortality 43/289). Overall mortality was higher in children with multiple organ and the phenotypes (24/101 vs 20/300; relative risk, 3.56; 95% CI, 2.06-6.17). Compared to the 188 multiple organ failure patients without these inflammation phenotypes, the 101 multiple organ failure patients with these phenotypes had both increased macrophage activation syndrome (19% vs 3%; relative risk, 7.07; 95% CI, 2.72-18.38) and mortality (24% vs 10%; relative risk, 2.35; 95% CI, 1.35-4.08). CONCLUSIONS These three inflammation phenotypes were associated with increased macrophage activation syndrome and mortality in pediatric sepsis-induced multiple organ failure. This study provides an impetus and essential baseline data for planning multicenter clinical trials targeting these inflammation phenotypes in children.

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating and categorizing indications for the evidence-based use of therapeutic apheresis (TA) in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Eighth Edition of the JCA Special Issue continues to maintain this methodology and rigor in order to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Eighth Edition, like its predecessor, continues to apply the category and grading system definitions in fact sheets. The general layout and concept of a fact sheet that was introduced in the Fourth Edition, has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of TA in a specific disease entity or medical condition. The Eighth Edition comprises 84 fact sheets for relevant diseases and medical conditions, with 157 graded and categorized indications and/or TA modalities. The Eighth Edition of the JCA Special Issue seeks to continue to serve as a key resource that guides the utilization of TA in the treatment of human disease.

[PMID: 31284692 PMCID: PMC6680968 DOI: 10.3390/medicina55070350] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Revised: 06/27/2019] [Accepted: 07/03/2019] [Indexed: 02/06/2023]
Abstract
Background and objective: Severe sepsis and septic shock are life-threatening organ dysfunctions and causes of death in critically ill patients. The therapeutic goal of the management of sepsis is restoring balance to the immune system and fluid balance. Continuous renal replacement therapy (CRRT) is recommended in septic patients, and it may improve outcomes in patients with severe sepsis or septic shock. Therapeutic plasma exchange (TPE) is another extracorporeal procedure that can improve organ function by decreasing inflammatory and anti-fibrinolytic mediators and correcting haemostasis by replenishing anticoagulant proteins. However, research about sepsis and CRRT and TPE in children has been insufficient and incomplete. Therefore, we investigated the reliability and efficacy of extracorporeal therapies in paediatric patients with severe sepsis or septic shock. Materials and methods: We performed a multicentre retrospective study using data from all patients aged <18 years who were admitted to two paediatric intensive care units. Demographic data and reason for hospitalization were recorded. In addition, vital signs, haemogram parameters, and biochemistry results were recorded at 0 h and after 24 h of CRRT. Patients were compared according to whether they underwent CRRT or TPE; mortality between the two treatment groups was also compared. Results: Between January 2014 and April 2019, 168 septic patients were enrolled in the present study. Of them, 47 (27.9%) patients underwent CRRT and 24 underwent TPE. In patients with severe sepsis, the requirement for CRRT was statistically associated with mortality (p < 0.001). In contrast, the requirement for TPE was not associated with mortality (p = 0.124). Conclusion: Our findings revealed that the requirement for CRRT in patients with severe sepsis is predictive of increased mortality. CRRT and TPE can be useful techniques in critically ill children with severe sepsis. However, our results did not show a decrease of mortality with CRRT and TPE.

Abstract
ADAMTS13 is an enzyme that acts by cleaving prothrombotic von Willebrand factor (VWF) multimers from the vasculature in a highly regulated manner. In pathologic states such as thrombotic thrombocytopenic purpura (TTP) and other thrombotic microangiopathies (TMAs), VWF can bind to the endothelium and form large multimers. As the anchored VWF chains grow, they provide a greater surface area to bind circulating platelets (PLTs), generating unique thrombi that characterize TTP. This results in microvasculature thrombosis, obstruction of blood flow, and ultimately end-organ damage. Initial presentations of TTP usually occur in an acute manner, typically developing due to an autoimmune response toward, or less commonly a congenital deficiency of, ADAMTS13. Triggers for TMAs that can be associated with ADAMTS13 deficiency, including TTP, have been linked to events that place a burden on hemostatic regulation, such as major trauma and pregnancy. The treatment plan for cases of suspected TTP consists of emergent therapeutic plasma exchange that is continued on a daily basis until normalization of PLT counts. However, a subset of these patients does not respond favorably to standard therapies. These patients necessitate a better understanding of their diseases for the advancement of future therapeutic options. Given ADAMTS13's key role in the cleavage of VWF and the prevention of PLT-rich thrombi within the microvasculature, future treatments may include anti-VWF therapeutics, recombinant ADAMTS13 infusions, and ADAMTS13 expression via gene therapy.

Abstract
Thrombocytopenia-associated multiple-organ failure (TAMOF) is an increasingly fatal phenomenon that may be associated with sepsis. TAMOF results from immune dysregulation and impaired activity of A Disintegrin And Metalloproteinase with ThromboSpondin type 1 motif, member 13. Early recognition of this premorbid condition and specific management results in a significantly improved outcome. Herein, we report the presentation and management of a 2-year-old child with TAMOF who was successfully treated with plasma exchange and recovered without long-term sequelae.

Abstract
OBJECTIVE To characterize the clinical indications, procedural safety, and outcome of critically ill children requiring therapeutic plasma exchange. DESIGN Retrospective observational study based on a prospective registry. SETTING Tertiary and quaternary referral 30-bed PICU. PATIENTS Forty-eight critically ill children who received therapeutic plasma exchange during an 8-year period (2007-2014) were included in the study. INTERVENTIONS Therapeutic plasma exchange. MEASUREMENTS AND MAIN RESULTS A total of 48 patients underwent 244 therapeutic plasma exchange sessions. Of those, therapeutic plasma exchange was performed as sole procedure in 193 (79%), in combination with continuous renal replacement therapy in 40 (16.4%) and additional extracorporeal membrane oxygenation in 11 (4.6%) sessions. The most common admission diagnoses were hematologic disorders (30%), solid organ transplantation (20%), neurologic disorders (20%), and rheumatologic disorders (15%). Complications associated with the procedure occurred in 50 (21.2%) therapeutic plasma exchange sessions. Overall, patient survival from ICU was 82%. Although patients requiring therapeutic plasma exchange alone (n = 31; 64%) had a survival rate of 97%, those with additional continuous renal replacement therapy (n = 13; 27%) and extracorporeal membrane oxygenation (n = 4; 8%) had survival rates of 69% and 50%, respectively. Factors associated with increased mortality were lower Pediatric Index of Mortality 2 score, need for mechanical ventilation, higher number of failed organs, and longer ICU stay. CONCLUSION Our results indicate that, in specialized centers, therapeutic plasma exchange can be performed relatively safely in critically ill children, alone or in combination with continuous renal replacement therapy and extracorporeal membrane oxygenation. Outcome in children requiring therapeutic plasma exchange alone is excellent. However, survival decreases with the number of failed organs and the need for continuous renal replacement therapy and extracorporeal membrane oxygenation.

Abstract
OBJECTIVES The American College of Critical Care Medicine provided 2002 and 2007 guidelines for hemodynamic support of newborn and pediatric septic shock. Provide the 2014 update of the 2007 American College of Critical Care Medicine "Clinical Guidelines for Hemodynamic Support of Neonates and Children with Septic Shock." DESIGN Society of Critical Care Medicine members were identified from general solicitation at Society of Critical Care Medicine Educational and Scientific Symposia (2006-2014). The PubMed/Medline/Embase literature (2006-14) was searched by the Society of Critical Care Medicine librarian using the keywords: sepsis, septicemia, septic shock, endotoxemia, persistent pulmonary hypertension, nitric oxide, extracorporeal membrane oxygenation, and American College of Critical Care Medicine guidelines in the newborn and pediatric age groups. MEASUREMENTS AND MAIN RESULTS The 2002 and 2007 guidelines were widely disseminated, translated into Spanish and Portuguese, and incorporated into Society of Critical Care Medicine and American Heart Association/Pediatric Advanced Life Support sanctioned recommendations. The review of new literature highlights two tertiary pediatric centers that implemented quality improvement initiatives to improve early septic shock recognition and first-hour compliance to these guidelines. Improved compliance reduced hospital mortality from 4% to 2%. Analysis of Global Sepsis Initiative data in resource rich developed and developing nations further showed improved hospital mortality with compliance to first-hour and stabilization guideline recommendations. CONCLUSIONS The major new recommendation in the 2014 update is consideration of institution-specific use of 1) a "recognition bundle" containing a trigger tool for rapid identification of patients with septic shock, 2) a "resuscitation and stabilization bundle" to help adherence to best practice principles, and 3) a "performance bundle" to identify and overcome perceived barriers to the pursuit of best practice principles.

Abstract
OBJECTIVES We hypothesize that three inflammation pathobiology phenotypes are associated with increased inflammation, proclivity to develop features of macrophage activation syndrome, and multiple organ failure-related death in pediatric severe sepsis. DESIGN Prospective cohort study comparing children with severe sepsis and any of three phenotypes: 1) immunoparalysis-associated multiple organ failure (whole blood ex vivo tumor necrosis factor response to endotoxin < 200 pg/mL), 2) thrombocytopenia-associated multiple organ failure (new onset thrombocytopenia with acute kidney injury and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 activity < 57%), and/or 3) sequential multiple organ failure with hepatobiliary dysfunction (respiratory distress followed by liver dysfunction with soluble Fas ligand > 200 pg/mL), to those without any of these phenotypes. SETTING Tertiary children's hospital PICU. PATIENTS One hundred consecutive severe sepsis admissions. INTERVENTIONS Clinical data were recorded daily, and blood was collected twice weekly. MEASUREMENTS AND MAIN RESULTS Multiple organ failure developed in 75 cases and eight died. Multiple organ failure cases with any of the three inflammation phenotypes (n = 37) had higher inflammation (C-reactive protein, p = 0.009 and ferritin, p < 0.001) than multiple organ failure cases without any of these phenotypes (n = 38) or cases with only single organ failure (n = 25). Development of features of macrophage activation syndrome and death were more common among multiple organ failure cases with any of the phenotypes (macrophage activation syndrome: 10/37, 27%; death: 8/37, 22%) compared to multiple organ failure cases without any phenotype (macrophage activation syndrome: 1/38, 3%; p = 0.003 and death: 0/38, 0%; p = 0.002). CONCLUSIONS Our approach to phenotype categorization remains hypothetical, and the phenotypes identified need to be confirmed in multicenter studies of pediatric multiple organ dysfunction syndrome.

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating, and categorizing indications for the evidence-based use of therapeutic apheresis in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the Committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Seventh Edition of the JCA Special Issue continues to maintain this methodology and rigor to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Seventh Edition, like its predecessor, has consistently applied the category and grading system definitions in the fact sheets. The general layout and concept of a fact sheet that was used since the fourth edition has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis in a specific disease entity. The Seventh Edition discusses 87 fact sheets (14 new fact sheets since the Sixth Edition) for therapeutic apheresis diseases and medical conditions, with 179 indications, which are separately graded and categorized within the listed fact sheets. Several diseases that are Category IV which have been described in detail in previous editions and do not have significant new evidence since the last publication are summarized in a separate table. The Seventh Edition of the JCA Special Issue serves as a key resource that guides the utilization of therapeutic apheresis in the treatment of human disease. J. Clin.

Transfusion 2017; 57:1407-1413. [PMID: 28266045 DOI: 10.1111/trf.14067] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2016] [Revised: 01/14/2017] [Accepted: 01/19/2017] [Indexed: 12/25/2022]
Abstract
BACKGROUND Treatment of necrotizing soft tissue infections (NSTIs) includes prompt surgical debridement and antibiotics, but despite standard care, the morbidity and mortality remain high. Since therapeutic plasma exchange (TPE) has been considered for treatment of severe sepsis, this study evaluates the efficacy of TPE for patients with NSTI. STUDY DESIGN AND METHODS This is a retrospective study of patients with diagnosis of NSTI who received treatment with and without TPE over an 11-year period. The primary outcome was in-hospital mortality. RESULTS Fifty-two patients with NSTI treated with TPE (TPE group) and 125 patients with NSTI not treated with TPE (non-TPE group) were assessed. Nineteen (36.5%) patients died in the TPE group, and 35 (28%) patients died in the non-TPE group. Within the TPE group, there was significant improvement in white blood cell (WBC) count and sodium levels 7 days after TPE treatment, but no improvement in creatinine. Inverse probability weighting based on propensity scores was used to compare survival in the TPE and non-TPE groups and demonstrated that TPE was associated with an increased odds of death (odds ratio, 2.8). A second analysis matched for six variables yielded 31 pairs and demonstrated no significant difference in mortality or length of stay. CONCLUSIONS This study describes the largest series of patients with NSTIs treated with TPE and showed no evidence of clinical benefit. Further carefully designed studies with meaningful clinical endpoints would prove useful in assessing reproducibility and determining if there is a role for TPE in other forms of severe sepsis.

Abstract
OBJECTIVE To describe the state of the science, identify knowledge gaps, and offer potential future research questions regarding promising therapies for children with multiple organ dysfunction syndrome presented during the Eunice Kennedy Shriver National Institute of Child Health and Human Development Workshop on Pediatric Multiple Organ Dysfunction Syndrome (March 26-27, 2015). DATA SOURCES Literature review, research data, and expert opinion. STUDY SELECTION Not applicable. DATA EXTRACTION Moderated by an expert from the field, issues relevant to the association of multiple organ dysfunction syndrome with a variety of conditions were presented, discussed, and debated with a focus on identifying knowledge gaps and research priorities. DATA SYNTHESIS Summary of presentations and discussion supported and supplemented by relevant literature. CONCLUSIONS Among critically ill children, multiple organ dysfunction syndrome is relatively common and associated with significant morbidity and mortality. For outcomes to improve, effective therapies aimed at preventing and treating this condition must be discovered and rigorously evaluated. In this article, a number of potential opportunities to enhance current care are highlighted including the need for a better understanding of the pharmacokinetics and pharmacodynamics of medications, the effect of early and optimized nutrition, and the impact of effective glucose control in the setting of multiple organ dysfunction syndrome. Additionally, a handful of the promising therapies either currently being implemented or developed are described. These include extracorporeal therapies, anticytokine therapies, antitoxin treatments, antioxidant approaches, and multiple forms of exogenous steroids. For the field to advance, promising therapies and other therapies must be assessed in rigorous manner and implemented accordingly.

Abstract
OBJECTIVE To describe the pathophysiology associated with multiple organ dysfunction syndrome in children. DATA SOURCES Literature review, research data, and expert opinion. STUDY SELECTION Not applicable. DATA EXTRACTION Moderated by an experienced expert from the field, pathophysiologic processes associated with multiple organ dysfunction syndrome in children were described, discussed, and debated with a focus on identifying knowledge gaps and research priorities. DATA SYNTHESIS Summary of presentations and discussion supported and supplemented by relevant literature. CONCLUSIONS Experiment modeling suggests that persistent macrophage activation may be a pathophysiologic basis for multiple organ dysfunction syndrome. Children with multiple organ dysfunction syndrome have 1) reduced cytochrome P450 metabolism inversely proportional to inflammation; 2) increased circulating damage-associated molecular pattern molecules from injured tissues; 3) increased circulating pathogen-associated molecular pattern molecules from infection or endogenous microbiome; and 4) cytokine-driven epithelial, endothelial, mitochondrial, and immune cell dysfunction. Cytochrome P450s metabolize endogenous compounds and xenobiotics, many of which ameliorate inflammation, whereas damage-associated molecular pattern molecules and pathogen-associated molecular pattern molecules alone and together amplify the cytokine production leading to the inflammatory multiple organ dysfunction syndrome response. Genetic and environmental factors can impede inflammation resolution in children with a spectrum of multiple organ dysfunction syndrome pathobiology phenotypes. Thrombocytopenia-associated multiple organ dysfunction syndrome patients have extensive endothelial activation and thrombotic microangiopathy with associated oligogenic deficiencies in inhibitory complement and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13. Sequential multiple organ dysfunction syndrome patients have soluble Fas ligand-Fas-mediated hepatic failure with associated oligogenic deficiencies in perforin and granzyme signaling. Immunoparalysis-associated multiple organ dysfunction syndrome patients have impaired ability to resolve infection and have associated environmental causes of lymphocyte apoptosis. These inflammation phenotypes can lead to macrophage activation syndrome. Resolution of multiple organ dysfunction syndrome requires elimination of the source of inflammation. Full recovery of organ functions is noted 6-18 weeks later when epithelial, endothelial, mitochondrial, and immune cell regeneration and reprogramming is completed.

Use of Therapeutic Plasma Exchange during Extracorporeal Life Support in Critically Ill Cardiac Children with Thrombocytopenia-Associated Multi-Organ Failure. Front Pediatr 2017; 5:254. [PMID: 29250516 PMCID: PMC5716972 DOI: 10.3389/fped.2017.00254] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Accepted: 11/14/2017] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Thrombocytopenia-associated multi-organ failure (TAMOF) in children is a well-described factor for increased hospital mortality. Low cardiac output syndrome (LCOS) and the effects of cardiopulmonary bypass may manifest with several adverse physiologic and immunologic effects, with varying degrees of thrombocytopenia and multi-organ dysfunction, sometimes very similar to TAMOF. LCOS is a common occurrence in children with critical heart disease, presenting in as much as 23.8% of infants postoperative of congenital heart surgery. Therapeutic plasma exchange (TPE) has been offered as a promising therapy for TAMOF; however, the therapeutic implications of this modality in children with critical heart disease and a clinical diagnosis of TAMOF are unknown. OBJECTIVES We describe our institutional experience with TPE as an adjuvant rescue therapy for children with critical heart disease and a clinical diagnosis of TAMOF, while supported by extracorporeal membrane oxygenation (ECMO). METHODS Single-center retrospective analysis of children with critical heart disease admitted to the CICU and supported by ECMO, undergoing TPE for a clinical diagnosis of TAMOF between January 2006 and June 2015. RESULTS Forty-one patients were included for analysis. Median age and weight of patients was 0.6 years (range 0.0-17.2) and 8.5 kg (range 1.5-80.0). TPE was initiated at a median of 1 day (0-13) after initiation of ECMO. Modified organ failure index (MOFI) and platelet count improved after TPE start (p < 0.001). Patients with early TPE initiation after ECMO cannulation (<1 day) showed more improvement in MOFI and platelet counts than patients with late TPE initiation (p < 0.001 for each). Overall survival to hospital discharge was 53.7%. The within-groups hospital survival was 73.3% for patients with heart failure, 34.8% for patients with congenital heart disease, and 100% for those with other cardiac disease (p = 0.016). CONCLUSION In children with critical cardiac disease and clinical diagnosis of TAMOF necessitating ECMO for hemodynamic support, concurrent TPE may be associated with an improvement in organ failure and platelet count, particularly when started early. Further studies are warranted to establish the most effective use of TPE and its effect on survival in this population.

Abstract
BACKGROUND Leptospirosis is a zoonotic infectious disease caused by pathogenic spirochetes of the genus Leptospira. Although it is usually asymptomatic and self-limited, severe potentially fatal illness accompanied by multi-organ failure may occur. CASE REPORT Here we report an unusual case of severe leptospirosis successfully treated with continuous venovenous hemofiltration (CVVHF) and therapeutic plasma exchange (TPE). The patient presented with pericardial tamponade, renal failure and macrophage activation syndrome, and later suffered prolonged jaundice and sclerosing cholangitis during hospitalization in the pediatric intensive care unit (PICU). To the best of our knowledge, sclerosing cholangitis due to leptospirosis has not been reported in the literature. CONCLUSION Leptospirosis should be kept in mind in the differential diagnosis of sepsis and septic shock with fever, thrombocytopenia, jaundice and renal failure. TPE and CVVHF should start early after the diagnosis of leptospirosis with multiorgan failure.

Abstract
TAMOF is a devastating microangiopathy that can occur in association with the new onset of T1DM, and should be considered with the onset of thrombocytopenia, renal failure, and raised LDH. Treatment with fresh frozen plasma should be considered as a first‐line option in such cases prior to plasma exchange.

Abstract
We describe a case of an infant with HSV meningitis and septic shock who demonstrated a remarkably high serum ferritin level. Aggressive pediatric intensive care and the administration of high-dose glucocorticoids were not able to reverse the multiple organ dysfunctions. Subsequent autopsy identified the presence of hemophagocytosis, thus the patient fulfilled hemophagocytic lymphohistiocytosis (HLH) criteria post-mortem. This case highlights that serum ferritin may be an important early indicator of mortality in sepsis due to a cytokine storm similar to macrophage activation syndrome and HLH.

CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2015; 19:324.

Abstract
INTRODUCTION Daily or serial evaluation of multiple organ dysfunction syndrome (MODS) scores may provide useful information. We aimed to validate the daily (d) PELOD-2 score using the set of seven days proposed with the previous version of the score. METHODS In all consecutive patients admitted to nine pediatric intensive care units (PICUs) we prospectively measured the dPELOD-2 score at day 1, 2, 5, 8, 12, 16, and 18. PICU mortality was used as the outcome dependent variable. The discriminant power of the dPELOD-2 scores was estimated using the area under the ROC curve and the calibration using the Hosmer-Lemeshow chi-square test. We used a logistic regression to investigate the relationship between the dPELOD-2 scores and outcome, and between the change in PELOD-2 score from day 1 and outcome. RESULTS We included 3669 patients (median age 15.5 months, mortality rate 6.1%, median length of PICU stay 3 days). Median dPELOD-2 scores were significantly higher in nonsurvivors than in survivors (p < 0.0001). The dPELOD-2 score was available at least at day 2 in 2057 patients: among the 796 patients without MODS on day 1, 186 (23.3%) acquired the syndrome during their PICU stay (mortality 4.9% vs. 0.3% among the 610 who did not; p < 0.0001). Among the 1261 patients with MODS on day 1, the syndrome worsened in 157 (12.4%) and remained unchanged or improved in 1104 (87.6%) (mortality 22.9% vs. 6.6%; p < 0.0001). The AUC of the dPELOD-2 scores ranged from 0.75 (95% CI: 0.67-0.83) to 0.89 (95% CI: 0.86-0.91). The calibration was good with a chi-square test between 13.5 (p = 0.06) and 0.9 (p = 0.99). The PELOD-2 score on day 1 was a significant prognostic factor; the serial evaluation of the change in the dPELOD-2 score from day1, adjusted for baseline value, demonstrated a significant odds ratio of death for each of the 7 days. CONCLUSION This study suggests that the progression of the severity of organ dysfunctions can be evaluated by measuring the dPELOD-2 score during a set of 7 days in PICU, providing useful information on outcome in critically ill children. Its external validation would be useful.

Abstract
Thrombocytopenia-associated multiple organ failure (TAMOF) is a clinical phenotype that encompasses a spectrum of syndromes associated with disseminated microvascular thromboses, such as the thrombotic microangiopathies thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS) and disseminated intravascular coagulation (DIC). Autopsies findings in TTP, HUS, or DIC reveal specific findings that can differentiate these 3 entities. Von Willebrand factor and ADAMTS-13 play a central role in TTP. Shiga toxins and the complement pathway are vital in the development of HUS. Tissue factor is the major protease that drives the pathology of DIC. Acute kidney injury (AKI) is a common feature in patients with TAMOF.

Abstract
OBJECTIVE To determine the effect of therapeutic plasma exchange on hemodynamics, organ failure, and survival in children with multiple organ dysfunction syndrome due to sepsis requiring extracorporeal life support. DESIGN A retrospective analysis. SETTING A PICU in an academic children's hospital. PATIENTS Fourteen consecutive children with sepsis and multiple organ dysfunction syndrome who received therapeutic plasma exchange while on extracorporeal life support from 2005 to 2013. INTERVENTIONS Median of three cycles of therapeutic plasma exchange with median of 1.0 times the estimated plasma volume per exchange. MEASUREMENTS AND MAIN RESULTS Organ Failure Index and Vasoactive-Inotropic Score were measured before and after therapeutic plasma exchange use. PICU survival in our cohort was 71.4%. Organ Failure Index decreased in patients following therapeutic plasma exchange (mean ± SD: pre, 4.1 ± 0.7 vs post, 2.9 ± 0.9; p = 0.0004). Patients showed improved Vasoactive-Inotropic Score following therapeutic plasma exchange (median [25th-75th]: pre, 24.5 [13.0-69.8] vs post, 5.0 [1.5-7.0]; p = 0.0002). Among all patients, the change in Organ Failure Index was greater for early therapeutic plasma exchange use than late use (early, -1.7 ± 1.2 vs late, -0.9 ± 0.6; p = 0.14), similar to the change in Vasoactive-Inotropic Score (early, -67.5 [28.0-171.2] vs late, -12.0 [7.2-18.5]; p = 0.02). Among survivors, the change in Organ Failure Index was greater among early therapeutic plasma exchange use than late use (early, -2.3 ± 1.0 vs late, -0.8 ± 0.8; p = 0.03), as was the change in Vasoactive-Inotropic Score (early, -42.0 [16.0-76.3] vs late, -12.0 [5.3-29.0]; p = 0.17). The mean duration of extracorporeal life support after therapeutic plasma exchange according to timing of therapeutic plasma exchange was not statistically different among all patients or among survivors. CONCLUSIONS The use of therapeutic plasma exchange in children on extracorporeal life support with sepsis-induced multiple organ dysfunction syndrome is associated with organ failure recovery and improved hemodynamic status. Initiating therapeutic plasma exchange early in the hospital course was associated with greater improvement in organ dysfunction and decreased requirement for vasoactive and/or inotropic agents.
