Abstract
This study aimed to evaluate the therapeutic efficacy and effect of blood purification (BP) therapy on severe acute pancreatitis (SAP). Information on 305 patients (BP group 68, control group 237) diagnosed with SAP was retrieved from the Medical Information Mart for Intensive Care IV (MIMIC IV) database. Firstly, the influence of BP treatment was preliminarily evaluated by comparing the outcome indicators of the two groups. Secondly, multiple regression analysis was used to screen the mortality risk factors to verify the impact of BP on the survival outcome of patients. Then, the effect of BP treatment was re-validated with baseline data. Finally, cox regression was used to make the survival curve after matching to confirm whether BP could affect the death outcome. The results indicated that the BP group had a lower incidence of shock (p = 0.012), but a higher incidence of acute kidney injury (AKI) (p < 0.001), with no differences observed in other outcome indicators when compared to the control group. It was also found that the 28-day survival curve of patients between the two groups was significantly overlapped (p = 0.133), indicating that BP treatment had no significant effect on the survival outcome of patients with SAP. Although BP is beneficial in stabilizing hemodynamics, it has no effect on short- and long-term mortality of patients. The application of this technology in the treatment of SAP should be done with caution until appropriate BP treatment methods are developed, particularly for patients who are not able to adapt to renal replacement therapy.

Abstract
ABSTRACT Background: It is unknown whether early renal replacement therapy (RRT) initiation strategy in intensive care unit (ICU) patients with both acute respiratory distress syndrome (ARDS) and sepsis with or without renal failure is clinically beneficial. Patients and methods: A total of 818 patients with both ARDS and sepsis admitted to the ICU of Tianjin Medical University General Hospital were included in the analysis. Early RRT was defined as initiating the RRT strategy within 24 h of admission. The relationship between early RRT and clinical outcomes, including primary (30-day mortality) and secondary (90-day mortality, serum creatinine, Pa o2 /Fi o2 , duration of invasive mechanical ventilation, cumulative fluid output, and cumulative fluid balance) outcomes, was compared using propensity score matching (PSM). Results: A total of 277 patients (33.9% of the total population) underwent an early RRT initiation strategy before PSM. After PSM, a cohort of 147 patients with early RRT and 147 patients without early RRT with matched baseline characteristics (including serum creatinine at admission) were constructed. Early RRT was not significantly associated with 30- (hazard ratio [HR], 1.25; 95% confidence interval [CI], 0.85-1.85; P = 0.258) or 90-day mortality (HR, 1.30; 95% CI, 0.91-1.87, P = 0.150). At each time point within 72 h after admission, there was no significant difference in serum creatinine, Pa o2 /Fi o2 and duration of mechanical ventilation between the early and the no early RRT groups. Early RRT significantly increased total output at all time points within 72 h of admission and reached a statistically significant negative fluid balance at 48 h. Conclusions: Early RRT initiation strategies had no statistically significant survival benefit in ICU patients with both ARDS and sepsis, with or without renal failure, nor did they significantly improve serum creatinine and oxygenation or shorten the duration of mechanical ventilation. The use and timing of RRT in such patients should be thoroughly investigated.

Abstract
Simple Summary Septic shock is a life-threatening disease caused by a dysregulated host response to infection, affecting millions of people every year and killing more than 25% directly despite advances in modern medicine. This pathology is characterized by apoptosis-induced depletion of immune cells and immunodepression. Many alterations in the expression of surface markers of neutrophils and monocytes have been described in septic patients. There is no specific treatment but the early identification and diagnosis of the pathology as well as timely treatment can greatly improve patient outcomes. The aim of this study was to inspect the recently published literature to inform the clinician about the most up-to-date techniques for the study of immune cell phenotypes and on the function of leukocytes of extracorporeal and non-blood purification treatments proposed for sepsis were also analyzed. The most important alteration observed in septic neutrophils is the activation of a survival program capable of resisting apoptotic death. As regards adaptive immunity, sepsis-induced apoptosis leads to lymphopenia in patients with septic shock and this process involves all types of T cells (CD4, CD8 and Natural Killer), except for regulatory T cells, favoring immunosuppression. Several promising therapies that target the host’s immune response to sepsis are currently under evaluation. Abstract Innate and adaptive immune system cells play a critical role in the host response to sepsis. Sepsis is a life-threatening disease characterized by apoptosis-induced depletion of immune cells and immunodepression, which contribute to morbidity and mortality. Many alterations in the expression of surface markers of neutrophils and monocytes have been described in septic patients. The aim of this study was to inspect the recently published literature to inform the clinician about the most up-to-date techniques for the study of circulating leukocytes. The impact on cell phenotypes and on the function of leukocytes of extracorporeal and non-blood purification treatments proposed for sepsis were also analyzed. We conducted a systematic review using Pubmed/Medline, Ovid/Willey, the Cochrane Library, the Cochrane Controlled Trials Register, and EMBASE, combining key terms related to immunological function in sepsis and selected the most relevant clinical trials and review articles (excluding case reports) published in the last 50 years. The most important alteration in neutrophils during sepsis is that they activate an anti-apoptotic survival program. In septic monocytes, a reduced characteristic expression of HLA-DR is observed, but their role does not seem to be significantly altered in sepsis. As regards adaptive immunity, sepsis leads to lymphopenia and immunosuppression in patients with septic shock; this process involves all types of T cells (CD4, CD8 and Natural Killer), except for regulatory T cells, which retain their function. Several promising therapies that target the host immune response are currently under evaluation. During the worldwide pandemic caused by SARS-CoV-2, it was useful to study the “cytokine storm” to find additional treatments, such as the oXiris® filter. This therapy can decrease the concentration of inflammatory markers that affect the severity of the disease.

Abstract
Critically ill COVID-19 patients are generally admitted to the ICU for respiratory insufficiency which can evolve into a multiple-organ dysfunction syndrome requiring extracorporeal organ support. Ongoing advances in technology and science and progress in information technology support the development of integrated multi-organ support platforms for personalized treatment according to the changing needs of the patient. Based on pathophysiological derangements observed in COVID-19 patients, a rationale emerges for sequential extracorporeal therapies designed to remove inflammatory mediators and support different organ systems. In the absence of vaccines or direct therapy for COVID-19, extracorporeal therapies could represent an option to prevent organ failure and improve survival. The enormous demand in care for COVID-19 patients requires an immediate response from the scientific community. Thus, a detailed review of the available technology is provided by experts followed by a series of recommendation based on current experience and opinions, while waiting for generation of robust evidence from trials.

Abstract
Sepsis is the primary cause of acute kidney injury in critically ill patients. During the past decades, several extracorporeal blood purification techniques have been developed for sepsis and sepsis-induced acute kidney injury management. These therapies could act on both the infectious agent itself and the host immune response. In this article, we review the available literature discussing the different extracorporeal blood purification techniques, including high-volume hemofiltration, cascade hemofiltration, hemoperfusion, coupled plasma filtration adsorption, plasma exchange, and specific optimized renal replacement therapy membranes.

Abstract
Acute kidney injury (AKI) affects many ICU patients and is responsible for increased morbidity and mortality. Although lifesaving in many situations, renal replacement therapy (RRT) may be associated with complications, and the appropriate timing of its initiation is still the subject of intense debate. An early initiation strategy can prevent some metabolic complications, whereas a delayed one may allow for renal function recovery in some patients without need for this costly and potentially dangerous technique. For years, most of the knowledge on this issue stemmed from observational studies or small randomized controlled trials. Recent randomized controlled trials have indicated that a watchful waiting strategy (in the absence of life-threatening conditions such as severe hyperkalemia or pulmonary edema) during severe AKI allowed many patients to escape RRT and did not seem to adversely affect survival compared with a strategy of immediate RRT. In addition, data suggest that a delayed strategy may reduce the rate of complications (such as catheter infection) and favor renal function recovery. Ongoing studies will have to both confirm these conclusions and clarify to what extent the delay in initiating RRT can be prolonged. Pending those results, the bulk of evidence suggests that, in the absence of potential severe complications of AKI, delaying RRT is a valid and safe strategy that may also allow for considerable cost savings.

Abstract
BACKGROUND Conventional pharmacologic therapies aim to reduce fluid overload in advanced heart failure (HF) represented by intravenous (IV) loop diuretics (LDs) have sometimes not so efficacious and been reported to have side effects such as unpredictable removal of water and sodium and electrolyte disturbance. It is not certain whether early ultrafiltration (UF) is effective than LDs in relieving edema. Given the weakness of evidence for early UF in patients with fluid overload, recommendations of UF in guidelines is considered as second-line therapy only for patients with refractory congestion, who failed to respond to LD-based strategies. METHODS The early continuous ultrafiltration in Chinese patients with congestive heart failure (EUC-CHF) trial is an open-label, registry-based, prospective study, recruiting patients with severe acute decompensated HF who are hospitalized for HF worsening due to overt fluid overload 24 h from hospital admission. Forty patients will be enrolled to two treatment groups (n = 20 for each group). The primary outcomes are the changes of weight loss and dyspnea severity score after treatment, as well as the occurrence of clinically overt major bleeding. DISCUSSION EUC-CHF trial was primarily designed to evaluate the efficacy and safety of early UF in patients with acute decompensated HF to reduce volume overload and improve clinical outcome. The trial aims to determine if early UF in acute HF is superior to IV LDs in clinical parameter improvement without adverse events and prevents rehospitalization up to 30 days. Also the trial is expected to establish a scoring system based on Chinese population to guide early UF treatment in appropriate patients. EUC-CHF is one of the first controlled trials tailored to determine the benefit of UF with 24 h from hospital admission. TRIAL REGISTRATION www.chictr.org.cn, ChiCTR1800019556.

Abstract
RATIONALE The optimal strategy for initiation of renal replacement therapy (RRT) in patients with severe acute kidney injury in the context of septic shock and acute respiratory distress syndrome (ARDS) is unknown. OBJECTIVES To examine the effect of an early compared with a delayed RRT initiation strategy on 60-day mortality according to baseline sepsis status, ARDS status, and severity. METHODS Post hoc analysis of the AKIKI (Artificial Kidney Initiation in Kidney Injury) trial. MEASUREMENTS AND MAIN RESULTS Subgroups were defined according to baseline characteristics: sepsis status (Sepsis-3 definition), ARDS status (Berlin definition), Simplified Acute Physiology Score 3 (SAPS 3), and Sepsis-related Organ Failure Assessment (SOFA). Of 619 patients, 348 (56%) had septic shock and 207 (33%) had ARDS. We found no significant influence of the baseline sepsis status (P = 0.28), baseline ARDS status (P = 0.94), and baseline severity scores (P = 0.77 and P = 0.46 for SAPS 3 and SOFA, respectively) on the comparison of 60-day mortality according to RRT initiation strategy. A delayed RRT initiation strategy allowed 45% of patients with septic shock and 46% of patients with ARDS to escape RRT. Urine output was higher in the delayed group. Renal function recovery occurred earlier with the delayed RRT strategy in patients with septic shock or ARDS (P < 0.001 and P = 0.003, respectively). Time to successful extubation in patients with ARDS was not affected by RRT strategy (P = 0.43). CONCLUSIONS Early RRT initiation strategy was not associated with any improvement of 60-day mortality in patients with severe acute kidney injury and septic shock or ARDS. Unnecessary and potentially risky procedures might often be avoided in these fragile populations. Clinical trial registered with www.clinicaltrials.gov (NCT 01932190).

Abstract
Background In the early stage of severe burn, patients often exhibit a high level of inflammatory mediators in blood and are likely to develop sepsis. High-volume haemofiltration (HVHF) can eliminate these inflammatory mediators. We hypothesised that early application of HVHF may be beneficial in reducing sepsis and improving the prognosis of patients with severe burns. Methods Adults patients with burns ≥ 50% total burn surface area (TBSA) and in whom the sum of deep partial and full-thickness burn areas was ≥ 30% were enrolled in this randomised prospective study, and they were divided into control (41 cases) and HVHF (41 cases) groups. Patients in the control group received standard management for major burns, whereas the HVHF group additionally received HVHF treatment (65 ml/kg/h for 3 consecutive days) within 3 days after burn. The incidence of sepsis and mortality, some laboratory data, levels of inflammatory cytokines in the blood, HLA-DR expression on CD14+ peripheral blood monocytes, the proportion of CD25+Foxp3+ in CD4+ T lymphocytes, and the counts of CD3+, CD4+ and CD8+ T lymphocytes were recorded within 28 days post-burn. Results The incidence of sepsis, septic shock and duration of vasopressor treatment were decreased significantly in the HVHF group. In addition, in the subgroup of patients with burns ≥ 80% TBSA, the 90-day mortality showed significant decreases in the HVHF group. The ratio of arterial oxygen partial pressure to the fraction of inspiration oxygen was improved after HVHF treatment. In the patients who received HVHF treatment, the blood levels of inflammatory cytokines, including tumour necrosis factor-α, interleukin (IL)-1β, IL-6 and IL-8, as well as the blood level of procalcitonin were found to be lower than in the control group. Moreover, higher HLA-DR expression on CD14+ monocytes and a lower proportion of CD25+Foxp3+ in CD4+ T lymphocytes were observed in the patients in the HVHF group. Conclusions Early application of HVHF benefits patients with severe burns, especially for those with a greater burn area (≥ 80% TBSA), decreasing the incidence of sepsis and mortality. This effect may be attributed to its early clearance of inflammatory mediators and the recovery of the patient’s immune status.

Abstract
Background Breakdown of the gut barrier increases intestinal permeability and allows movement of intraluminal contents across the mucosa, which can lead to distant organ injury and multiple organ dysfunction syndrome (MODS). Intestinal permeability is associated with alterations in cellular tight junctions involving the structural proteins occludin and zonula occludens-1 (ZO-1). The aim of this study was to investigate the effect of continuous blood purification (CBP) on gut barrier function in patients with MODS. Method Serum diamine oxidase (DAO) and endotoxin, epithelial monolayer permeability, and transepithelial electrical resistance (TER) were used as markers for the assessment of gut barrier function in 22 patients with MODS who underwent continuous venovenous hemofiltration (CVVH) for 24 hours. Blood samples were taken from patients at 0, 6, 12, and 24 hours during CVVH therapy. Serum DAO and endotoxin were determined by spectrophotography. Permeability and TER were assessed using Caco-2 cell monolayers. Occludin and ZO-1 protein levels were analyzed by immunoblotting and immunofluorescence staining. And inducible nitric oxide synthase (iNOS) mRNA levels and nitric oxide (NO) production were determined by real-time PCR and spectrophotography, respectively. Result Gut barrier dysfunction was evident in patients with MODS compared with normal controls. Serum DAO, endotoxin levels, and epithelial permeability were elevated, while TER was decreased in patients with MODS, and this change was more pronounced in nonsurvivors. Breakdown and reorganization of occludin and ZO-1 away from tight junctions was found in all MODS patients. After CBP treatment, APACHE II and MODS scores improved significantly. Serum DAO and endotoxin levels and epithelial permeability also diminished, while TER increased in all patients; CBP significantly attenuated breakdown and reorganization of tight junction proteins, and also attenuated the inflammation-induced increase in iNOS mRNA expression and NO production. Conclusion Breakdown of gut barrier function is present in patients with MODS and may be correlated with poor outcomes in the disease. CBP can not only improve the general conditions, as measured by the APACHE II score, but also improve gut barrier dysfunction by attenuating the breakdown and reorganization of occludin and ZO-1. This beneficial effect of CBP on gut barrier dysfunction is associated with down-regulation of iNOS.

Abstract
Objectives The aim of this study was to investigate the effect of continuous blood purification (CBP) on early gut mucosal dysfunction in patients with severe acute pancreatitis (SAP). Methods Patients with SAP were randomized to receive 24 hours of continuous veno-venous hemofiltration (CVVH; n=33) or no CVVH (n=30). Blood samples were taken from the patients at 0, 6, 12, and 24 hours during CVVH therapy. Serum diamine oxidase (DAO) and endotoxin, epithelial permeability, transepithelial electrical resistance (TER) and F-actin rearrangement of the epithelial monolayer were used as the markers for the assessment of gut barrier function and the effect of CBP therapy in patients with SAP. Results Patients with SAP had increased levels of serum DAO, endotoxin, and epithelial permeability when compared with normal controls, and the increase was more pronounced in patients with organ dysfunction (p<0.01). F-actin rearrangement, loose cell-cell junction, and iNOS mRNA upregulation were found in all patients. After CBP treatment, Acute Physiology and Chronic Health Evaluation II score and SOFA score improved significantly; levels of serum DAO, endotoxin, and epithelial permeability decreased (p<0.05). CBP also significantly attenuated reorganization of actin and downregulated iNOS mRNA expression and NO production (p<0.05). Conclusions CBP can not only improve the general conditions but also effectively improve gut barrier dysfunction. The beneficial effect of CBP on gut barrier dysfunction is associated with the improvement of cytoskeletal instability, by downregulating iNOS through the removal of excess proinflammatory factors.

Abstract
Since the last decade, hemofiltration and especially high volume hemofiltration has rapidly evolved from a somewhat experimental treatment towards a potentially effective “adjunctive” therapy in severe septic shock and especially refractory or catecholamine resistant hypodynamic septic shock. Nevertheless, this approach lacks prospective randomized studies (PRT'S) evaluating the critical role of early hemofiltration in sepsis. An important step forward which could be called the “big bang” in term of hemofiltration was the publication of a PRT in patients with acute renal failure (ARF) (1). Before this study (2), nobody believed that hemofiltration could change the survival rate in intensive care. Since that big bang, many physicians consider that hemofiltration at a certain dose can change the survival rate in intensive care. So the world of hemofiltration in ICU is not a definitive world, it is still in expansion. Indeed, we now have to try to define what will be the exact dose we need in septic acute renal failure. This dose might well be “higher” than 35 ml/kg/hour in the septic acute renal failure “group” as suggested by many studies (2–5). At present, it is the issue of continuous dose of high volume hemofiltration that has to be tested in future randomized studies. Since the Vicenza study (2) has shown that 35 ml/kg/h is the best dose in terms of survival, dealing with non septic acute renal failure in ICU, several studies from different groups have shown that, in septic acute renal failure, a higher dose might correlate with better survival. This has also been shown in some way by the study of the “Vicenza group” but not with a statistically significant value (2). New PRT'S have just started in Europe like the IVOIRE study (hIgh VOlume in Intensive caRE) (6) and the RENAL study. Another large study is looking more basically at dose in non septic acute renal failure in Australasia and is led by the group of Rinaldo Bellomo in Melbourne (7) as well as the ATN study (8) led by Palevsky and colleagues in the USA, also testing the importance of dose in the treatment for ARF. Nevertheless, “early goal-directed hemofiltration therapy” like early goal directed therapy (9) has to be studied in our critical ill patients. Regarding this issue, fewer studies, mainly retrospective exist, but again the IVOIRE study (6) will address this issue by studying septic patients with acute renal injury according to the Rifle classification (10). So, this review focuses on the early application and on the adequate dose of continuous high volume hemofiltration in septic shock in order to improve not only hemodynamics, but survival in this very severely ill cohort of patients. This could well be called the “big bang of hemofiltration” as one could never have anticipated that an adequate dose of hemofiltration could markedly influence the survival rate of ICU-septic acute renal failure patients. On top of the use of early and adequate dose of hemofiltration in sepsis, a higher dose could also provide better renal recovery rate and reduce the risk of associate chronic dialysis in these patients. Furthermore, this paper also reviews “brand” new theories regarding the rationale for hemofiltration in sepsis. Finally, this paper also addresses the so-called negative studies as well anticipated side effects.

Abstract
Background Extracorporeal blood purification treatment (EBT) methods have been used in the treatment of experimental and human SIRS/Sepsis in a variety of settings and with variable reports of efficacy and safety. Their role in the management of SIRS/Sepsis remains controversial. Objectives To develop consensus statements regarding important aspects of research, practice and technical management concerning EBT. Methods Systematic review of published study. Evidence-based grading of information available. Consensus development regarding fundamental questions about EBT. Results Consensus was achieved on all questions posed during the conference. It was agreed that there is currently a clear biological rational for EBT in SIRS and Sepsis. It was agreed that conventional CVVH has sufficiently been shown not to be effective in SIRS/Sepsis in the absence of concomitant ARF and that other therapies such as plasmapheresis or high-volume hemofiltration or coupled plasma filtration adsorption appear more promising and should be tested in multicentre randomized controlled trials. Patients with ARF and SIRS/Sepsis should be treated differently from those with ARF alone even though current practice in this field is not well known. Patients with refractory septic shock should be considered for EBT. Appropriate end points for clinical trials can be defined and chosen according to the goals of the trial. Different technologies exist for EBT and better understanding of the merits and safety of each is needed as well as better standardization of methodology and dose. Conclusions Broad consensus can be achieved on several aspects of EBT and can be used to inform clinical practice and to help guide the establishment of a future research agenda.

Abstract
Objective Monocyte and its secreted cytokines play a crucial role in the process of severe acute pancreatitis (SAP). It has been known that continuous veno-venous hemofiltration (CVVH) can partially attenuate the inflammatory process by removal of cytokines, but the effect of CVVH on monocyte secretion function remains unknown. This study investigated the effect of different doses of CVVH on monocyte secretion function as well as the plasma cytokine profile in a SAP porcine model. Methods After successful induction of SAP by pressure-controlled (100 mmHg), intraductal injection of sodium taurocholate (4%, 1 ml/kg) and trypsin (2 U/kg), 24 swine were randomly assigned to 3 groups. Swine in group I (n=8) serving as SAP controls received only standard medical therapy (SMT). Besides SMT, swine in two other groups received zero-balanced CVVH, one hour after the induction of SAP, with low volume fluid exchange (group II, n=8, ultrafiltration rate (UFR) 20 ml/kg/h, LV-CVVH) or high volume (group III, n=8, UFR 100 ml/kg/h, HV-CVVH). Using heparin as anticoagulant, the filter (AN69, Hospal, Lyon, France) was changed every 24 hours. Monocytes were isolated from porcine blood at various timepoints for detection of cytokine secretion (interleukin-6, IL-6; interleukin-10, IL-10; tumor necrosis-α, TNF-α) after LPS stimulus; plasma cytokines were measured simultaneously. Results CVVH showed a dose-dependent beneficial effect on the animals’ survival time. In control animals, plasma pro-inflammatory cytokine levels exhibited a double-phase fluctuation after SAP induction: IL-6 and TNF-α rapidly increased to a peak level within 6–12 hours, then dropped to very low level in the late stage. Unlike pro-inflammatory cytokines, the plasma level of anti-inflammatory cytokine IL-10 reached a plateau within 6–12 hours but dropped little. In CVVH-treated animals, the peak-nadir patterns of 3 cytokines were all flattened, most prominently in the HV-CVVH group. Similarly to plasma cytokine patterns, the monocyte ex vivo response to LPS stimulus showed an over-production of cytokines within 6–12 hours, but low production in the late stage. Although unable to totally prevent the abnormality of the monocyte secretion function, CVVH showed a dose-dependent ameliorative effect on it. Conclusions Monocytes are over-reactive to stimulus in the early stage of SAP, accompanied by a high level of plasma cytokines, and hypo-reactive to stimulus in the late stage of SAP, accompanied with a low level of plasma cytokines. CVVH treatment has a dose-dependent improvement effect on monocyte responsiveness.

Abstract
Despite the great advances in the treatment of sepsis over the past 20 years, sepsis remains the main cause of death in intensive care units. In the context of new possibilities of treating sepsis, a comprehensive response of the immune system to the infection, immunosuppression, in particular, has in recent years gained considerable interest. There is vast evidence pointing to the correlation between comorbid immunosuppression and an increased risk of recurrent infections and death. Immune disorders may impact the clinical course of sepsis. This applies in particular to patients with deteriorated clinical response to infections. They usually suffer from comorbidities and conditions accompanied by immunosuppression. Sepsis disrupts innate and adaptive immunity. The key to diagnose the immune disorders in sepsis and undertake targeted immunomodulatory therapy is to define the right biomarkers and laboratory methods, which permit prompt "bedside" diagnosis. Flow cytometry is a laboratory tool that meets these criteria. Two therapeutic methods are currently being suggested to restore the immune homeostasis of sepsis patients. Excessive inflammatory response may be controlled through extracorporeal blood purification techniques, in large part derived from renal replacement therapy. These are such techniques as high-volume haemofiltration, cascade haemofiltration, plasma exchange, coupled plasma filtration and adsorption, high-absorption membranes, high cut-off membranes. The main task of theses techniques is the selective elimination of middle molecular weight molecules, such as cytokines. Pharmacotherapy with the use of such immunostimulants as interleukin 7, granulocyte-macrophage colony-stimulating factor, interferon gamma, PD-1, PD-L1 and CTLA-4 antagonists, intravenous immunoglobulins may help fight immunosuppressive immune disorders.

Abstract
AIMS The study aimed to assess the clinical benefits of high-volume hemofiltration (HVHF) in pediatric patients with severe sepsis compared with standard-volume continuous veno-venous hemofiltration (CVVH). METHODS We retrospectively analyzed the medical records of 155 pediatric patients with severe sepsis admitted to the pediatric intensive care unit of Shanghai Children's Hospital from January 2010 to June 2016. A total of 93 patients were treated with HVHF and 62 patients were treated with CVVH. RESULTS HVHF treatment did not significantly reduce 28-day mortality. Moreover, there was no significant difference in reducing the plasma level of inflammatory mediators and improving hemodynamic variables between HVHF and CVVH group. However, the incidence of hyperglycemia was significantly higher in HVHF group than in CVVH group. CONCLUSIONS There is no evidence to indicate that HVHF is superior to CVVH in reducing 28-day mortality as an adjunct to the treatment of severe sepsis in pediatric patients.

Abstract
It is now well established that profound immunosuppression develops within a few days after sepsis onset in patients. This should be considered additional organ failure because it is associated with increased rate of nosocomial infections, mortality, and long-term complications, thus constituting the rationale for immunomodulation in patients. Nevertheless, the demonstration of the efficacy of such therapeutic strategy in improving deleterious outcomes in sepsis remains to be made. Results from clinical trials based on interleukin 7 and granulocyte macrophage colony-stimulating factor immunoadjuvant therapies in septic shock patients are expected for 2018.

Abstract
BACKGROUND Dysfunction of the intestinal mucosal barrier plays an important role in the pathophysiology of severe acute pancreatitis (SAP). Continuous blood purification (CBP) has been shown to improve the prognosis of SAP patients. In order to investigate the effect of CBP on intestinal mucosal barrier dysfunction in SAP patients with MODS, we conducted in vivo and in vitro experiments to explore the underlying mechanisms. METHODS The markers for the assessment of intestinal mucosal barrier function including serum diamine oxidase (DAO), endotoxin and intestinal epithelial monolayer permeability were detected during CBP therapy. The distribution and expression of cytoskeleton protein F-actin and tight junction proteins claudin-1 were observed. In addition, Rho kinase (ROCK) mRNA expression and serum tumor necrosis factor-alpha (TNF-α) levels during CBP were determined. RESULTS SAP patients with MODS had increased levels of serum DAO, endotoxin and intestinal epithelial monolayer permeability when compared with normal controls. While the distribution of F-actin and claudin-1 was rearranged, and the expression of claudin-1 significantly decreased, but F-actin had no change. Meanwhile, ROCK mRNA expression and serum TNF-α level were increased. However, after CBP treatment, levels of serum DAO, endotoxin and intestinal epithelial monolayer permeability decreased. The F-actin and claudin-1 reorganization attenuated and the expression of claudin-1 increased. At the same time, ROCK mRNA expression and serum TNF-α level were decreased. CONCLUSIONS CBP can effectively improve intestinal mucosal barrier dysfunction. The beneficial effect is associated with the improvement of cytoskeleton and tight junction proteins in stability by downregulation of ROCK mRNA expression through the removal of excess proinflammatory factors.

Abstract
INTRODUCTION Sepsis is a dysregulated host immune response due to an uncontrolled infection. It is a leading cause of mortality in adult intensive care units globally. When the host immune response induced against a local infection fails to contain it locally, it progresses to sepsis, severe sepsis, septic shock and death. METHOD Literature survey was performed on the roles of different innate and adaptive immune cells in the development and progression of sepsis. Additionally, the effects of septic changes on reprogramming of different immune cells were also summarized to prepare the manuscript. FINDINGS Scientific evidences to date suggest that the loss of balance between inflammatory and anti-inflammatory responses results in reprogramming of immune cell activities that lead to irreversible tissue damaging events and multi-organ failure during sepsis. Many surface receptors expressed on immune cells at various stages of sepsis have been suggested as biomarkers for sepsis diagnosis. Various immunomodulatory therapeutics, which could improve the functions of immune cells during sepsis, were shown to restore immunological homeostasis and improve survival in animal models of sepsis. CONCLUSION In-depth and comprehensive knowledge on the immune cell activities and their correlation with severity of sepsis will help clinicians and scientists to design effective immunomodulatory therapeutics for treating sepsis.

[PMID: 27336018 PMCID: PMC4905158 DOI: 10.1177/2333794x16645699] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Revised: 03/22/2016] [Accepted: 03/25/2016] [Indexed: 12/14/2022] Open
Abstract
The efficacy and therapeutic mechanisms of continuous renal replacement therapy (CRRT) for improvement of oxygenation in acute respiratory distress syndrome (ARDS) remain controversial. These questions were addressed by retrospective analysis of severe ARDS patients admitted to the pediatric intensive care unit of our hospital from 2009 to 2015 who received high-volume continuous veno-venous hemofiltration during mechanical ventilation. There was a significant improvement in partial oxygen pressure/fraction of inspired oxygen (PaO2/FiO2) 24 hours after CRRT onset compared with baseline (median change = 51.5; range = −19 to 450.5; P < .001) as well as decreases in FiO2, peak inspiratory pressure, positive end-expiratory pressure, and mean airway pressure (P < .05). The majority of patients had a negative fluid balance after 24 hours of CRRT. White blood cell (WBC) count decreased in the subgroup with high baseline WBC count (P < .05). PaO2/FiO2 was higher in ARDS patients with extrapulmonary etiology than in those with pulmonary etiology (P < .05). Improvement in oxygenation is likely related to both restoration of fluid balance and clearance of inflammatory mediators.

Abstract
Cells of the innate and adaptive immune systems play a critical role in the host response to sepsis. Moreover, their accessibility for sampling and their capacity to respond dynamically to an acute threat increases the possibility that leukocytes might serve as a measure of a systemic state of altered responsiveness in sepsis.The working group of the 14th Acute Dialysis Quality Initiative (ADQI) conference sought to obtain consensus on the characteristic functional and phenotypic changes in cells of the innate and adaptive immune system in the setting of sepsis. Techniques for the study of circulating leukocytes were also reviewed and the impact on cellular phenotypes and leukocyte function of nonextracorporeal treatments and extracorporeal blood purification therapies proposed for sepsis was analyzed.A large number of alterations in the expression of distinct neutrophil and monocyte surface markers have been reported in septic patients. The most consistent alteration seen in septic neutrophils is their activation of a survival program that resists apoptotic death. Reduced expression of HLA-DR is a characteristic finding on septic monocytes, but monocyte antimicrobial function does not appear to be significantly altered in sepsis. Regarding adaptive immunity, sepsis-induced apoptosis leads to lymphopenia in patients with septic shock and it involves all types of T cells (CD4, CD8, and Natural Killer) except T regulatory cells, thus favoring immunosuppression. Finally, numerous promising therapies targeting the host immune response to sepsis are under investigation. These potential treatments can have an effect on the number of immune cells, the proportion of cell subtypes, and the cell function.

Abstract
This study aimed to assess the effects of early fluid resuscitation (EFR) combined with high volume hemofiltration (HVHF) on the cardiopulmonary function and removal of inflammatory mediators in a septic shock swine model. Eighteen swine were randomized into three groups: control (n = 6) (extracorporeal circulating blood only), continuous renal replacement therapy (CRRT) (n = 6; ultrafiltration volume = 25 mL/Kg/h), and HVHF (n = 6; ultrafiltration volume = 85 mL/Kg/h). The septic shock model was established by intravenous infusion of lipopolysaccharides (50 µg/kg/h). Hemodynamic parameters (arterial pressure, heart rate, cardiac output, stroke volume variability, left ventricular contractility, systemic vascular resistance, and central venous pressure), vasoactive drug parameters (dose and time of norepinephrine and hourly fluid intake), pulmonary function (partial oxygen pressure and vascular permeability), and cytokines (interleukin-6 and interleukin-10) were observed. Treatment resulted in significant changes at 4-6 h. HVHF was beneficial, as shown by the dose of vasoactive drugs, fluid intake volume, left ventricular contractility index, and partial oxygen pressure. Both CRRT and HVHF groups showed improved removal of inflammatory mediators compared with controls. In conclusion, EFR combined with HVHF improved septic shock in this swine model. The combination decreased shock progression, reduced the need for vasoactive drugs, and alleviated the damage to cardiopulmonary functions.

Abstract
PURPOSE We compared hemodynamic and biological effects of the Cascade system, which uses very high volume hemofiltration (HVHF) (120 mL kg(-1) h(-1)), with those of usual care in patients with septic shock. METHODS Multicenter, prospective, randomized, open-label trial in three intensive care units (ICU). Adults with septic shock with administration of epinephrine/norepinephrine were eligible. Patients were randomized to usual care plus HVHF (Cascade group), or usual care alone (control group). Primary end point was the number of catecholamine-free days up to 28 days after randomization. Secondary end points were number of days free of mechanical ventilation, renal replacement therapy (RRT) or ICU up to 90 days, and 7-, 28-, and 90-day mortality. RESULTS We included 60 patients (29 Cascade, 31 usual care). Baseline characteristics were comparable. Median number of catecholamine-free days was 22 [IQR 11-23] vs 20 [0-25] for Cascade vs control; there was no significant difference even after adjustment. There was no significant difference in number of mechanical ventilation-free days or ICU requirement. Median number of RRT-free days was 85 [46-90] vs 74 [0-90] for Cascade vs control groups, p = 0.42. By multivariate analysis, the number of RRT-free days was significantly higher in the Cascade group (up to 25 days higher after adjustment). There was no difference in mortality at 7, 28, or 90 days. CONCLUSION Very HVHF using the Cascade system can safely be used in patients presenting with septic shock, but it was not associated with a reduction in the need for catecholamines during the first 28 days.

Abstract
OBJECTIVES This study aimed to conduct a single-center prospective trial of short-term continuous high-volume hemofiltration (HVHF) in patients with predicted severe acute pancreatitis (SAP). METHODS Patients with acute pancreatitis with Acute Physiology and Chronic Health Evaluation II scores of greater than 15 on admission between January 2008 and December 2010 were allocated to receive either optimal standard therapy or 72 hours of continuous HVHF on an alternate basis, beginning as soon as possible after admission. Biomarkers and clinical outcomes were compared between the 2 groups. RESULTS A total of 61 patients received either conventional therapy (n = 29) or HVHF (n = 32). High-volume hemofiltration treatment was associated with a significant reduction in the incidence of renal failure (P = 0.013), infected pancreatic necrosis (P = 0.048), length of hospitalization (P = 0.005), mortality (P = 0.033), as well as duration of renal (P < 0.001), respiratory (P = 0.002), and hepatic failure (P = 0.001). Acute Physiology and Chronic Health Evaluation II score and C-reactive protein and interleukin 6 levels were significantly reduced after the start of HVHF on days 1, 3, and 7 (all, P < 0.05). CONCLUSIONS This study suggests that short-term HVHF may reduce local and systemic complications and mortality in patients with SAP with Acute Physiology and Chronic Health Evaluation score of greater than 15.

Abstract
As an initial factor, sepsis and multiple organ dysfunction syndrome (MODS) caused by sepsis are the principal causes of death in burned patients. In this report, we measured the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in severely burned patients with sepsis after the initiation of continuous vein-vein hemodiafiltration (CVVHDF) to evaluate the clinical usefulness of CVVHDF on the removal of key mediators. The vital sign indices, such as the heart rate (HR), respiration (R) and central venous pressure (CVP), were recorded at 0 and 42 h in each group. Further, the laboratory examinations indexes, such as the white blood cell count, blood sugar, serum sodium, blood urea nitrogen and serum creatinine, were detected in venous blood samples. Twenty-two severely burned patients suffering from sepsis were randomized into the control group (A, n = 11) and the experimental group (B, n = 11). The patients in group A underwent conventional treatment, and those in group B received conventional+CVVHDF treatment. The vital signs, such as the HR, R, and CVP, and laboratory examination indices, such as the blood cell count, blood sugar, serum sodium, blood urea nitrogen, and serum creatinine, dropped significantly in group B compared with those in group A at 42 h (P < 0.05). The plasma levels of TNF-α, IL-6 and IL-8 were measured at 0, 12, 18, 24, 36 and 42 h after the start of CVVHDF and at the same time points after the patients were diagnosed with sepsis in group A. The plasma levels of TNF-α in group B decreased by 32% at 18 h after the start of CVVHDF and decreased by 43% at 42 h after the start of CVVHDF; however, these levels were increased compared with the normal values (P < 0.01). The plasma levels of IL-6 decreased at 18 h after the start of CVVHDF (0.274 ± 0.137 ng/ml). Following a brief increase at 24 h, the plasma levels of IL-6 again decreased continuously until the end of the investigation (0.192 ± 0.119 ng/ml). The plasma levels of IL-8 in group B decreased by 56% at 18 h after the start of CVVHDF, but they were increased compared with the normal values (P < 0.01). The plasma levels of IL-8 in group B decreased by 70% at 42 h after the start of CVVHDF, but they were increased compared with the normal values (P < 0.01). The MODS incident was 4 of 11 in group A compared with 1 of 11 in group B (P < 0.01). In conclusion, CVVHDF can effectively reduce the levels of TNF-α, IL-6 and IL-8 as well as the MODS incidence in patients with serious burns.

Abstract
PURPOSE Septic shock is a leading cause of death among critically ill patients, in particular when complicated by acute kidney injury (AKI). Small experimental and human clinical studies have suggested that high-volume haemofiltration (HVHF) may improve haemodynamic profile and mortality. We sought to determine the impact of HVHF on 28-day mortality in critically ill patients with septic shock and AKI. METHODS This was a prospective, randomized, open, multicentre clinical trial conducted at 18 intensive care units in France, Belgium and the Netherlands. A total of 140 critically ill patients with septic shock and AKI for less than 24 h were enrolled from October 2005 through March 2010. Patients were randomized to either HVHF at 70 mL/kg/h or standard-volume haemofiltration (SVHF) at 35 mL/kg/h, for a 96-h period. RESULTS Primary endpoint was 28-day mortality. The trial was stopped prematurely after enrolment of 140 patients because of slow patient accrual and resources no longer being available. A total of 137 patients were analysed (two withdrew consent, one was excluded); 66 patients in the HVHF group and 71 in the SVHF group. Mortality at 28 days was lower than expected but not different between groups (HVHF 37.9 % vs. SVHF 40.8 %, log-rank test p = 0.94). There were no statistically significant differences in any of the secondary endpoints between treatment groups. CONCLUSIONS In the IVOIRE trial, there was no evidence that HVHF at 70 mL/kg/h, when compared with contemporary SVHF at 35 mL/kg/h, leads to a reduction of 28-day mortality or contributes to early improvements in haemodynamic profile or organ function. HVHF, as applied in this trial, cannot be recommended for treatment of septic shock complicated by AKI.

Abstract
BACKGROUND AND AIMS Extracorporeal cytokine removal may be desirable. We sought to assess extracorporeal blood purification (EBP) techniques for cytokine removal in experimental animal studies.
METHODS We conducted a targeted, systematic search and identified 17 articles. We analyzed cytokine clearance, sieving coefficient (SC), ultrafiltrate (UF) concentration, and percentage removal. As this review concerns technical appraisal of EBP techniques, we made no attempts to appraise the methodology of the studies included. Results are in descriptive terms only.
RESULTS Applying predicted clearance for 80 kg human, high volume hemofiltration (HVHF) techniques and plasmafiltration (PF) showed the highest rates of cytokine removal. High cutoff (HCO)/HF and PF techniques showed modest ability to clear cytokines using low to medium flows. Standard hemofiltration had little efficacy. At higher flows, HCO/HF achieved clearances between 30 and 70 ml/min for IL-6 and IL-10. There was essentially no removal of tumor necrosis factor (TNF)-alpha outside of PF.
CONCLUSIONS Experimental animal studies indicate that HVHF (especially with HCO filters) and plasmafiltration have the potential to achieve appreciable IL-6 and IL-10 clearances. However, only PF can remove TNF-alpha reliably.

Abstract
UNLABELLED Improper compartmentalization of the inflammatory response leads to systemic inflammation in sepsis. Hemoadsorption (HA) is an emerging approach to modulate sepsis-induced inflammation. We sought to define the effects of HA on inflammatory compartmentalization in Escherichia coli-induced fibrin peritonitis in rats. HYPOTHESIS HA both reprograms and recompartmentalizes inflammation in sepsis. Sprague Dawley male rats were subjected to E. coli peritonitis and, after 24 h, were randomized to HA or sham treatment (sepsis alone). Venous blood samples collected at 0, 1, 3 and 6 h (that is, 24-30 h of total experimental sepsis), and peritoneal samples collected at 0 and 6 h, were assayed for 14 cytokines along with NO(2)(-/)NO(3)(-). Bacterial counts were assessed in the peritoneal fluid at 0 and 6 h. Plasma tumor necrosis factor (TNF)-α, interleukin (IL)-6, CXCL-1, and CCL2 were significantly reduced in HA versus sham. Principal component analysis (PCA) suggested that inflammation in sham was driven by IL-6 and TNF-α, whereas HA-associated inflammation was driven primarily by TNF-α, CXCL-1, IL-10 and CCL2. Whereas -peritoneal bacterial counts, plasma aspartate transaminase levels and peritoneal IL-5, IL-6, IL-18, interferon (IFN)-γ and NO(2)(-)/NO(3)(-) were significantly lower, both CXCL-1 and CCL2 as well as the peritoneal-to-plasma ratios of TNF-α, CXCL-1 and CCL2 were significantly higher in HA versus sham, suggesting that HA-induced inflammatory recompartmentalization leads to the different inflammatory drivers discerned in part by PCA. In conclusion, this study demonstrates the utility of combined in vivo/in silico methods and suggests that HA exerts differential effects on mediator gradients between local and systemic compartments that ultimately benefit the host.

Abstract
OBJECTIVE Cytokines initiate and modify systemic inflammatory response in early acute pancreatitis. The aim of this study was to analyze which cytokines are released from the pancreas to portal venous blood in the early phase of acute experimental necrotizing and oedematous pancreatitis and which of those cytokines are correlated with the more severe form of the disease. MATERIAL AND METHODS Fifteen pigs were randomized to develop mild oedematous pancreatitis (n = 5, saline infusion to pancreatic duct), severe necrotizing pancreatitis (n = 5, taurocholic acid infusion) along with a control group (n = 5). Arterial and venous blood samples were drawn and cytokine levels were measured from portal vein blood at 0, 120, 240 and 360 min after the induction of pancreatitis. Tissue samples from the pancreas were harvested at 0 and 360 min. RESULTS White blood cell count increased in necrotizing pancreatitis and the control group. The amount of neutrophils increased (p < 0.001) and the lymphocyte and eosinophil counts decreased in all groups (p < 0.001, p < 0.001). The monocyte count, as well as PDGF and IL-6 concentrations, increased only in necrotizing pancreatitis. IL-8 and eotaxin increased both in oedematous and necrotizing pancreatitis. MCP-1 increased in all groups. IL-9, IL-4, MIP-1α, IFN- γ concentrations did not change. Eotaxin and MCP-1 plasma levels from a previous series between portal venous and pulmonary arterial blood were not significantly different. CONCLUSIONS The initial inflammatory process was diverse in oedematous and necrotizing pancreatitis. Increased monocyte count in combination with elevated PDGF and IL-6 are characteristic of necrotizing pancreatitis in our model.

Abstract
Increasing evidence indicates that the expression of tumor necrosis factor-α (TNF-α) in myocardium correlates with the severity of cardiac dysfunction in septic shock. The aim of this study was to investigate the impact of high-volume hemofiltration (HVHF) on the expression of TNF-α in myocardium in septic shock pigs. Sixteen male Landrace pigs weighing 31 ± 5 kg were randomly assigned to control group (n = 4), septic shock group (n = 6), and HVHF group (septic shock + HVHF, n = 6). All animals were anesthetized and mechanically ventilated. After baseline examinations, septic shock group and HVHF group underwent induction of peritonitis. One hour later, the animals in HVHF group received treatment with HVHF and the treatment was continued for 12 h. As the control of HVHF group, the animals in septic shock group received the same support but hemofiltration. Twelve hours after HVHF therapy, all the animals were sacrificed. TNF-α and nitric oxide (NO) levels in both circulation and myocardium were measured. Compared with those of septic shock animals, the levels of cardiac output, stroke volume, and mean arterial pressure were better maintained in HVHF group. The expression of TNF-α in myocardium in HVHF group was lower than that in septic shock group (44.17 ± 18.70 vs. 92.50 ± 33.89 pg/mg protein, P = 0.015). The difference of TNF-α in circulation between HVHF group and septic shock group was no significance at different time. However, circulating NO in HVHF group was lower than that in septic shock group. These results suggest that HVHF improves hemodynamics and heart dysfunction in septic shock pigs, which may be attributed to reduction of TNF-α in myocardium but not in circulation.

Abstract
CONTEXT Multiple organ dysfunction syndrome (MODS) is a major cause of death in critically patients. It has been hypothesized that inactivation or removal of pro-inflammatory molecules may prevent or reverse MODS. OBJECTIVE The purpose of this paper was to investigate the efficacy of continuous veno-venous hemodiafiltration (CVVHDF) as treatment for MODS in an established animal model. MATERIALS AND METHODS Male Beagle dogs (n = 18) were used to establish the model and were randomly assigned to a CVVHDF, sham, or control group. The serum levels of ALT, AST, Cr, BUN, PaO(2), and PaCO(2) were measured as functional makers of major organs. Apoptosis, DLA-DR expression, and cytokine levels of peripheral monocytes were determined. RESULTS The MODS model was successfully established. After CVVHDF treatment, the WBC and neutrophil counts were lower and the monocyte count and percentage were greater, but these were unchanged in the sham and control groups. Apoptosis of CD14+ monocytes was significantly lower in the CVVHDF group than in the sham and control groups. The fraction of DLA-DR(+) monocytes and IL-1β secretion was significantly greater in the sham and control groups than in the CVVHDF group. Moreover, IL-4 secretion increased significantly in the CVVHDF group but not in the control group. DISCUSSION AND CONCLUSION Our study of an experimental model of MODS indicated that MODS leads to significant disruption of physiological and immune functions. CVVHDF treatment alleviated some of these symptoms due to the improvement of monocyte function, reduction of monocyte apoptosis, and increase of anti-inflammatory cytokines.

Abstract
Acute pancreatitis is a serious complication of pregnancy. In recent years, hypertriglyceridemia has become a common cause of acute pancreatitis, and up to 56% of pancreatitis cases during pregnancy are caused by hypertriglyceridemia. The majority of cases of hyperlipidemic pancreatitis in pregnancy belong to severe pancreatitis, and are commonly seen in the second and third trimester, easily recurrent, and dangerous. As hyperlipidemic pancreatitis in pregnancy is associated with a perinatal and maternal mortality of 20% to 50%, it seriously threatens maternal health and fetal lives. Now great efforts have been made to reduce the incidence of this complication and deaths of mothers and fetuses, and avoid the deformity of the baby. This article aims to review the progress in the treatment of hyperlipidemic pancreatitis in pregnancy.

Abstract
The treatment of sepsis is an ongoing challenge for clinicians; despite the wide choice of effective antibiotics to treat infection, sepsis remains the leading cause of morbidity and mortality for patients admitted to an intensive care unit. Dysregulation of the immune response is now recognized to be a key factor in multiple organ dysfunction, yet our therapy for inflammation remains ineffective. It has been advocated for more than a decade that cytokine reduction in blood compartment could lead to a reduction in mortality in sepsis. Over the years, multiple extracorporeal techniques have evolved, with the intent of influencing the circulating levels of inflammatory mediators like cytokines and chemokines, the complement system, as well as factors of the coagulation system. These include high-volume hemofiltration, use of high cutoff membranes, and systems based on adsorption, such as coupled plasma filtration adsorption and the polymyxin-B column. In addition, new experimental systems that utilize human phagocytic cells and immobilized antibodies for targeted immunomodulation have emerged. In the context of limited resources and growing expansion in the availability of technologies, a better understanding of these therapies is required before they can be properly integrated into standard clinical practice in the hope of influencing major clinical outcomes. In this article, we will provide a concise overview of selected extracorporeal modalities currently in clinical use and briefly introduce some new promising techniques for sepsis.

Abstract
Continuous renal replacement therapy (CRRT) is the preferred treatment for acute kidney injury in intensive care units (ICUs) throughout much of the world. Despite the widespread use of CRRT, controversy and center-specific practice variation in the clinical application of CRRT continue. In particular, whereas two single-center studies have suggested survival benefit from delivery of higher-intensity CRRT to patients with acute kidney injury in the ICU, other studies have been inconsistent in their results. Now, however, two large multi-center randomized controlled trials - the Veterans Affairs/National Institutes of Health Acute Renal Failure Trial Network (ATN) study and the Randomized Evaluation of Normal versus Augmented Level (RENAL) Replacement Therapy Study - have provided level 1 evidence that effluent flow rates above 25 mL/kg per hour do not improve outcomes in patients in the ICU. In this review, we discuss the concept of dose of CRRT, its relationship with clinical outcomes, and what target optimal dose of CRRT should be pursued in light of the high-quality evidence now available.

Abstract
Several functional abnormalities in phagocytes from patients with liver cirrhosis contribute to an increased risk of infection. An increased resting respiratory burst has been observed in neutrophils from cirrhotic patients. We investigated whether an infection in cirrhosis affects the respiratory burst capacity of neutrophils and monocytes in response to Escherichia coli. This study included 45 hospitalized patients with liver cirrhosis and clinical signs of infection, 39 patients with liver cirrhosis in the absence of infection and 29 healthy subjects. Respiratory burst, lipopolysaccharide-binding protein (LBP), and immunoglobulin (Ig)G-autoantibodies against oxidized low-density lipoproteins (ab-oxLDL) were measured. The fraction of neutrophils spontaneously producing reactive oxygen species (ROS) was elevated in liver cirrhosis (P < 0·01). The neutrophil resting burst increased with Child-Pugh stage (P = 0·02) and correlated with augmented ROS release in response to opsonized E. coli (P < 0·05). Although LBP was increased in patients with cirrhosis (P < 0·01), higher LBP levels correlated with a lower resting burst in neutrophils (r(s) = -0·395; P < 0·01). In the presence of infection, the resting burst was unaltered. However, neutrophil ROS release in response to E. coli was reduced markedly (P = 0·01), and it decreased as serum C-reactive protein (CRP) concentration rose (r(s) = -0·437; P < 0·01), indicating the development of a sepsis-like immune paralysis. A positive correlation between ab-oxLDL and ROS release was observed (P < 0·01). In conclusion, the respiratory burst increases with severity of liver cirrhosis but is restrained by increasing LBP levels. Augmented ROS release in response to E. coli is accompanied by elevated markers of oxidative damage and becomes exhausted in the presence of infection.

Abstract
Severe sepsis and septic shock are conditions associated with high morbidity and mortality. The disproportionate release of pro-inflammatory and anti-inflammatory mediators caused by the septic insult is the promoter of multiple organ dysfunction. Conventional hemodialysis, hemofiltration or a combination of both can be a good option to replace the deteriorating renal function in critically ill patients by the removal of nitrogen compounds (small molecules). However, this "renal dose" is insufficient for the removal of inflammatory mediators (medium molecules), and therefore contributes little to the cardiovascular stabilization of patients with septic shock. In this setting, a higher dose of ultrafiltration (> 50 ml/kg/h) or "septic dose" may be needed. In this review article, we have analyzed the clinical and pathophysiological rationale for the use of high volume hemofiltration in patients with septic shock.

Abstract
Triglyceride levels greater than 1,000 mg/dL may cause severe pancreatitis, and there is mounting evidence for the use of plasmapheresis to remove triglycerides for the treatment of triglyceride-induced pancreatitis. The failure of continuous venovenous hemodialysis (CVVHD) due to severe lipemia, necessitating plasmapheresis in the early phase of severe acute hypertriglyceridemia-induced pancreatitis, is reported. We suggest that in the setting of hypertriglyceridemia-induced pancreatitis with urgent indication for dialysis, plasmapheresis be initiated prior to CVVHD to prevent rheologic failure.

Abstract
BACKGROUND/AIMS Etanercept is a tumor necrosis factor-alpha antagonist used in inflammation-mediated conditions. Continuous venovenous hemofiltration (CVVH) has also been used in patients with inflammatory conditions. This study evaluated etanercept clearance using an in vitro CVVH model. METHODS Etanercept clearance was assessed in vitro in bovine blood at 1-3 mg/l final serum concentration, and urea control at 750 mg/l. CVVH was performed using polyacrylonitrile, polysulfone, and polymethylmethacrylate filters at 3 l/h ultrafiltrate and 200 ml/min blood flow rates. Transmembrane clearance was estimated using sieving coefficient calculations, and adsorptive removal rate was approximated using a mass balance calculation. RESULTS Urea sieving coefficient remained constant (1.04 +/- 0.01). Ultrafiltrate etanercept concentrations were undetectable (sieving coefficient < 0.02) and transmembrane and adsorptive clearances were negligible. CONCLUSION Etanercept is not cleared appreciably by transmembrane or adsorptive mechanisms in CVVH using polyacrylonitrile, polysulfone, or polymethylmethacrylate hemofilters.

Abstract
High-volume hemofiltration (HVHF) has been suggested as an adjuvant treatment of septic shock because of its capacities to remove inflammatory mediators from blood. Nevertheless, HVHF presents some important drawbacks, such as the depletion of low molecular weight molecules (nutriments, vitamins, trace elements and antibiotics) due to the high ultrafiltration rate, or the significant financial cost and nursing workload due to the frequent changes of large amounts of expensive sterile substitution fluids. A new hemofiltration system called "Cascade" has been developed, allowing very high ultrafiltration rates (120 mL/kg/h) limiting these drawbacks by using a special extracorporeal circuit. The objective of this study was to assess the technical feasibility of the Cascade system and to compare its hemodynamic impact to that of the standard HVHF system. Twenty sepsis-induced pigs were randomized in two groups: one group was hemofiltered with the standard HVHF system and the other with the Cascade system during a six-hour session. No technical problems were observed with the Cascade system during the experiment. At the end of the experiment, colloid requirements (989 +/- 355 mL vs. 1913 +/- 538 mL, P = 0.006), epinephrine requirements (0.82 +/- 0.42 mg vs. 3.27 +/- 3.02 mg, P < 0.001), lactic acidosis (pH = 7.33 +/- 0.08 vs. 7.10 +/- 0.07, P < 0.001) and mean pulmonary arterial pressure were less pronounced in the Cascade group. These results suggest that Cascade hemofiltration is technically feasible and safe. Moreover, compared with standard HVHF, it can reduce the severity of porcine septic shock.

Abstract
BACKGROUND Continuous renal replacement therapy (CRRT) showed promising results in the management of critically ill patients with systemic inflammatory response syndrome (SIRS)/sepsis. However, the underlying mechanism is still not very clear. A change of immune homeostasis in critically ill patients during CRRT was observed only to a smaller degree. OBJECTIVE The purpose of this study was to test the hypothesis that high-volume continuous venovenous hemofiltration (HV-CVVH) treatment could improve monocyte function and restore immune homeostasis in patients with severe acute pancreatitis (SAP). METHODS This was a prospective clinical trial in the surgical intensive care unit of a teaching hospital. Subjects were 16 patients with severe acute pancreatitis: sepsis group (n=7): positive culture result and in the late phase of disease (from onset of SAP to receiving CVVH therapy: more than 3 days); and nonseptic group (n=9): negative culture result and early phase of disease (less than 3 days). Patients received 72 hours of HV-CVVH. We measured the change in mean arterial pressure, APACHE II score, monocyte functions (including antigen-presenting and cytokine production ability), and plasma cytokines. RESULTS Mean arterial pressure were stable accompanied with APACHE II score improvements. HLA-DR expression on monocytes (antigen-presenting ability) were markedly decreased (p<0.0001) in all patients. Lipopolysaccharide (LPS)-induced TNF-alpha, interleukin-6 (IL-6), and IL-10 production from patients' monocytes markedly decreased in septic patients, but significantly increased in nonseptic patients. During HV-CVVH treatment, HLA-DR expression was markedly increased in nonseptic patients in 24 hours (p<0.05), and in septic patients in 72 hours (p<0.05). LPS-induced cytokine production was decreased in nonseptic patients, but not significantly changed in septic patients. The change of plasma cytokines showed the same trend. CONCLUSIONS In patients with SAP, HV-CVVH was associated with improved hemodynamics. HV-CVVH restores monocytes functions, especially in patients in the early phase of the disease and without sepsis. These findings suggest a potential role for HV-CVVH in the treatment of SAP.
