Concurrent use of continuous kidney replacement therapy during extracorporeal membrane oxygenation: what pediatric nephrologists need to know-PCRRT-ICONIC practice points.

[PMID: 38386072 DOI: 10.1007/s00467-024-06311-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/15/2024] [Accepted: 01/27/2024] [Indexed: 02/23/2024]
Abstract
Extracorporeal membrane oxygenation (ECMO) provides temporary cardiorespiratory support for neonatal, pediatric, and adult patients when traditional management has failed. This lifesaving therapy has intrinsic risks, including the development of a robust inflammatory response, acute kidney injury (AKI), fluid overload (FO), and blood loss via consumption and coagulopathy. Continuous kidney replacement therapy (CKRT) has been proposed to reduce these side effects by mitigating the host inflammatory response and controlling FO, improving outcomes in patients requiring ECMO. The Pediatric Continuous Renal Replacement Therapy (PCRRT) Workgroup and the International Collaboration of Nephrologists and Intensivists for Critical Care Children (ICONIC) met to highlight current practice standards for ECMO use within the pediatric population. This review discusses ECMO modalities, the pathophysiology of inflammation during an ECMO run, its adverse effects, various anticoagulation strategies, and the technical aspects and outcomes of implementing CKRT during ECMO in neonatal and pediatric populations. Consensus practice points and guidelines are summarized. ECMO should be utilized in patients with severe acute respiratory failure despite the use of conventional treatment modalities. The Extracorporeal Life Support Organization (ELSO) offers guidelines for ECMO initiation and management while maintaining a clinical registry of over 195,000 patients to assess outcomes and complications. Monitoring and preventing fluid overload during ECMO and CKRT are imperative to reduce mortality risk. Clinical evidence, resources, and experience of the nephrologist and healthcare team should guide the selection of ECMO circuit.

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.

Abstract
Therapeutic plasma exchange (TPE) is used for a variety of illnesses in critically ill pediatric patients. Although both centrifugation and filtration are known to be effective methods, to our knowledge, clinical results for TPE by these methods are not compared in pediatric patient populations. One hundred patients who had TPE for a variety of diagnoses were included in the study. In 55 patients plasma exchange was implemented by centrifugation and in 45, by filtration. These two groups were further divided into subgroups according to admittance diagnoses. The demographic information, admittance Pediatric Risk of Mortality scores, Pediatric Logistic Organ Dysfunction (PELOD) scores before beginning of therapy and PELOD at the end of therapy, durations of ventilatory support, pediatric intensive care unit and hospital stay, and outcomes were compared. Although the survival was significantly better in filtration group, it included more patients with neurologic diagnoses. Filtration group standard mortality rate was 0.6. In both groups, the PELOD scores after the termination of TPE were significantly decreased compared to that before beginning of TPE. Within thrombotic microangiopathy and hemophagocytic lymphohistiocytosis subgroups, median PELOD scores before treatment were higher in centrifugation patients but survival was similar with both methods. Both methods of TPE are alike in decreasing PELOD scores. In the filtration group, survival benefit of TPE is evident. In thrombotic microangiopathy patients, despite higher PELOD scores in the centrifugation group, survival is similar for both methods. These findings should be retested in randomized studies and the underlying physiology awaits to be uncovered.

Abstract
Since the advent of extracorporeal membrane oxygenation (ECMO) over 40 years ago, there has been increasing interest in the use of the extracorporeal circuit as a platform for providing multiple organ support. In this review, we will examine the evidence for the use of continuous renal replacement therapy, therapeutic plasma exchange, leukopheresis, adsorptive therapies, and extracorporeal liver support in conjunction with ECMO.

Abstract
The role of extracorporeal therapies (ECTs) in sepsis is unclear and is a strongly debated topic in critical-care medicine. Unfortunately, much of this debate arises because we lack a clear understanding of what defines the stage and severity of the disease, and the pivotal pathophysiological events dictating outcomes. In the absence of this knowledge, ECTs remain among a large group of therapies with high promise but unproven efficacy.

Abstract
Sepsis is the primary cause of death in the intensive care unit. Extracorporeal blood purification therapies have been proposed for patients with sepsis in order to improve outcomes since these therapies can alter the host inflammatory response by non-selective removal of inflammatory mediators or bacterial products or both. Recent technological progress has increased the number of techniques available for blood purification and their performance. In this overview, we report on the latest advances in blood purification for sepsis and how they relate to current concepts of disease, and we review the current evidence for high-volume hemofiltration, cascade hemofiltration, hemoadsorption, coupled plasma filtration adsorption, high-adsorption hemofiltration, and high-cutoff hemofiltration/hemodialysis. Promising results have been reported with all of these blood purification therapies, showing that they are well tolerated, effective in clearing inflammatory mediators or bacterial toxins (or both) from the plasma, and efficacious for improvement of various physiologic outcomes (for example, hemodynamics and oxygenation). However, numerous questions, including the timing, duration, and frequency of these therapies in the clinical setting, remain unanswered. Large multicenter trials evaluating the ability of these therapies to improve clinical outcomes (that is, mortality or organ failure), rather than surrogate markers such as plasma mediator clearance or transient improvement in physiologic variables, are required to define the precise role of blood purification in the management of sepsis.

Abstract
The American Society for Apheresis (ASFA) Apheresis Applications Committee is charged with a review and categorization of indications for therapeutic apheresis. Beginning with the 2007 ASFA Special Issue (fourth edition), the subcommittee has incorporated systematic review and evidence-based approach in the grading and categorization of indications. This Fifth ASFA Special Issue has further improved the process of using evidence-based medicine in the recommendations by refining the category definitions and by adding a grade of recommendation based on widely accepted GRADE system. The concept of a fact sheet was introduced in the Fourth edition and is only slightly modified in this current edition. The fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis. The article consists of 59 fact sheets devoted to each disease entity currently categorized by the ASFA as category I through III. Category IV indications are also listed.

Abstract
Anesthesiologists often care for patients with renal insufficiency or renal failure. These patients may present to the operating room for a minor procedure such as an inguinal hernia repair or an arteriovenous fistula/graft. Alternatively, they may present for major abdominal operations or coronary artery bypass grafting. Critically ill patients presenting to the operating room may have acute kidney injury. It is imperative that the anesthesiologist understands the ramifications of renal failure and adjusts the anesthetic plan accordingly. Hemodynamic monitoring and fluid management can be challenging in this patient population. Various metabolic abnormalities can ensue that the anesthesiologist must be able to manage in the acute setting of the operating room.

Abstract
A high index of suspicion for bacterial sepsis and recognition of the potential for rapid deterioration is essential for impacting patient outcome. Meningococcemia produces a stereotypical clinical and biochemical constellation of profound septic shock and purpura fulminans with marked inflammatory disturbance and a complex disruption of coagulation. Meningococcal infections preferentially affect infants and young children, but adolescents are also at risk. Aggressive fluid resuscitation, hemodynamic management, and clinical monitoring are based on understanding of pathophysiologic disturbances typical of the pediatric cardiovascular response and guided by evidence-based guidelines. Appropriate antibiotic choice is important, and corticosteroid use may be beneficial. A variety of efforts to manipulate the coagulation abnormalities may be considered, although evidence is lacking. Extracorporeal support remains a consideration both for the failing cardiorespiratory systems but also potentially for the use of plasma exchange. A team approach between the intensivist and subspecialist is important in managing the frequent multiorgan complications seen with meningococcemia.

Abstract
BACKGROUND It has been proposed that plasmapheresis is most effective when applied early in Gram-negative sepsis. We therefore studied the effect of early plasmapheresis on immunity in experimental Escherichia coli endotoxin-induced sepsis. METHODS 20 pigs received 30 microg/kg of E. coli endotoxin. 40 min later, half of the pigs were treated with plasmapheresis which lasted 4 h. The adhesion molecules, the oxidative burst, the number of neutrophils in blood and lungs, and cytokines were measured. RESULTS Infusion of endotoxin was associated with activation of adhesion molecules increased oxidative burst, increased concentration of cytokine, and accumulation of granulocytes in lung tissue. Plasmapheresis reduced the oxidative burst, and there was a tendency towards a reduced accumulation of granulocytes in the lung. CONCLUSION Though plasmapheresis was initiated early after the endotoxin infusion, it only temporarily attenuated a part of the activated cell-mediated immunity.

Abstract
OBJECTIVE To describe our institutional experience in the management of infants and children with pertussis admitted during a 20-yr period (January 1985 through December 2004) and also to study the relation between method of presentation and outcome. SETTING Pediatric intensive care unit in a university-affiliated tertiary pediatric hospital in Melbourne, Australia. DESIGN/METHODS Retrospective review of medical records and radiology reports of patients with a diagnosis of pertussis identified from the pediatric intensive care unit database. RESULTS A total of 49 patients (median age, 6 wks; interquartile range, 4-8 wks) required 55 admission episodes to the pediatric intensive care unit. Main reasons for admission were apnea with or without cough paroxysms (63%), pneumonia (18%), and seizures (10%). None of the infants had completed the primary course of immunization, and 94% had not received a single dose of pertussis vaccine. Infants presenting with pneumonia presented earlier (p = .001), had longer intensive care stay (p = .007), higher white cell count (p < or = .001), lower Pao2 at admission (p = .020), and higher mortality. Six infants out of seven needing circulatory support died (including all four treated with extracorporeal membrane oxygenation), and all deaths (n = 7) occurred in infants who had pneumonia at presentation. CONCLUSION Patients with pertussis, presenting as apnea (with or without cough paroxysms), treated in the pediatric intensive care unit had 100% survival. However, pneumonia as the main reason for admission and the need for circulatory support is associated with a very poor outcome. A deeper understanding of the molecular basis of Bordetella pertussis and its relation to the human host might offer means for future therapies.

Abstract
AIM Sepsis is characterized by an uncontrolled release of pro-inflammatory and anti-inflammatory mediators leading to immunoparalysis, cellular and humoral dysfunction, multiorgan dysfunction and death. This study evaluated the efficacy of high-volume haemofiltration (HVHF) compared with continuous venovenous haemofiltration (CVVH) in removing these inflammatory mediators. Clinical responses were assessed with the sequential organ failure assessment (SOFA) score. METHODS Septic patients with an end-organ dysfunction or septic shock were randomized to receive 6 h of CVVH (ultrafiltration dose of 2 L/h equivalent to about 35 mL/kg per hour or HVHF (ultrafiltration dose of 100 mL/kg per hour or 6 L/h, whichever was higher). The sequential organ failures were scored for the 24 hours preceding recruitment; at day 1, day 7, at discharge from the intensive care unit and at hospital discharge. RESULTS Thirty-three patients were enrolled. Fifteen received HVHF and 18 received CVVH. The serum IL-6 levels (pg/mL) at baseline were similarly elevated in both groups (P = 0.745). The HVHF group showed a significant reduction after 6 h of treatment with a median interquartile range (IQR) of 20.62 (49.21) pg/mL (P = 0.025) with no similar result in the CVVH group. Non-survivors showed a higher baseline serum IL-6 compared with the survivors (median (IQR) 172.31 (261.34) vs 58.9 (104.21), P = 0.044). In the HVHF group there was a positive association between the IL-6 levels at 6 h with the SOFA scores at day 1 (r = 0.392, P = 0.001) but not at day 7. After 6 h of treatment in the HVHF group there was a direct correlation between the IL-6 levels and number of hospital days (r = 0.90, P = 0.040). The maximum SOFA scores were persistently recorded before treatment. The SOFA scores reduced in both groups from baseline to day 7 (HVHF P = 0.048; CVVH P = 0.006). The SOFA scores at day 1 is significantly higher in the non-survivors compared with the survivors (P = 0.038). CONCLUSIONS High-volume haemofiltration at 6 L/h may seem to successfully remove some inflammatory cytokines in septic patients. The improvement in the SOFA scores at day 7 promises benefit of continuous renal replacement therapy in septic patients, but after 20 days this effect may be lost. In addition, the baseline serum IL-6 and IL-1-ra were independent predictors of a poor outcome as reflected by the higher SOFA scores at day 1.

Abstract
The American Society for Apheresis (ASFA) Apheresis Applications Committee is charged with a review and categorization of indications for therapeutic apheresis. This elaborate process had been undertaken every 7 years resulting in three prior publications in 1986, 1993, and 2000 of "The ASFA Special Issues." This article is the integral part of the Fourth ASFA Special Issue. The Fourth ASFA Special Issue is significantly modified in comparison to the previous editions. A new concept of a fact sheet has been introduced. The fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis. A detailed description of the fact sheet is provided. The article consists of 53 fact sheets devoted to each disease entity currently categorized by the ASFA. Categories I, II, and III are defined as previously in the Third Special Issue. However, a few new therapeutic apheresis modalities, not yet approved in the United States or are currently in clinical trials, have been assigned category P (pending) by the ASFA Clinical Categories Subcommittee. The diseases assigned to category IV are discussed in a separate article in this issue.

Abstract
Physicians often scan a select number of journals to keep up to date with practice evidence for patients with kidney conditions. This raises the question of where relevant studies are published. We performed a bibliometric analysis using 195 renal systematic reviews. Each review used a comprehensive method to identify all primary studies for a focused clinical question relevant to patient care. We compiled all the primary studies included in these reviews, and considered where each study was published. Of the 2779 studies, 1351 (49%) were published in the top 20 journals. Predictably, this list included Transplantation Proceedings (5.9% of studies), Kidney International (5.3%), American Journal of Kidney Diseases (4.7%), Nephrology Dialysis Transplantation (4.3%), Transplantation (4.2%), and Journal of the American Society of Nephrology (2.4%). Ten non-renal journals were also on this list, including New England Journal of Medicine (2.4%), Lancet (2.3%), and Diabetes Care (2.2%). The remaining 1428 (51%) studies were published across other 446 journals. When the disciplines of all journals were considered, 59 were classified as renal or transplant journals (42% of articles). Other specialties included general and internal medicine (16%), endocrinology (diabetes) and metabolism (6.5%), surgery (6.2%), cardiovascular diseases (6.1%), pediatrics (4.3%), and radiology (3.3%). About half of all renal practice evidence is published in non-renal journals. Browsing the top journals is important. However, relevant studies are also scattered across a large range of journals that may not be routinely scanned by busy physicians, and keeping up with this literature requires other continuing education strategies.

Abstract
In critically injured patients, the incidence of acute renal failure has been reported to occur in as many as 31% of patients. The use of CRRT modalities for patients following traumatic injuries is becoming more common, albeit slowly, and this therapy may impact upon long-term recovery of renal function and mortality. Historical studies investigating the early use of intermittent dialysis reported significant improvement in survival in patients who were dialyzed earlier and more vigorously than in control subjects. Early trauma patients also showed improved survival following war injuries when dialyzed prophylactically. Although there is a growing acceptance in favor of earlier renal replacement therapy, the published consensus and the practice in many centers has been to dialyze/filter relatively ill rather than relatively healthy patients. The R Adams Cowley Shock Trauma Center (STC) in Baltimore, Maryland, USA, admits over 8,000 trauma patients each year. Within the STC, a program of continuous renal replacement therapy was established in the early 1980's. We review both historical and current literature on the use of renal replacement therapies after traumatic injury, and suggest some future areas of investigation and indications for these modalities.

Abstract
Desire to restore the balance of body elements has enamored physicians since the ancient practice of bloodletting. More recently, extracorporeal techniques have been employed in both adults and children in treating sepsis. Extracorporeal therapies include continuous renal replacement (CRRT), plasma-based removal techniques, and extracorporeal membrane oxygenation (ECMO). These treatments could theoretically 1) provide immunohomeostasis of pro- and anti-inflammatory cytokines and other sepsis mediators, 2) decrease organ microthrombosis through removal of pro-coagulant factors and modulating the impaired septic coagulation response in sepsis, and 3) provide mechanical support of organ perfusion during the acute septic episode to allow time for response to traditional sepsis therapies and antimicrobials. CRRT is beneficial in managing fluid overload and acute renal failure in sepsis. Removal of sepsis mediators through the technique is variable, and the outcome impact of CRRT on sepsis has not been definitively determined. High-flow CRRT has demonstrated benefit in septic adults. Intriguing early results suggest that plasma exchange could improve outcomes in both adults and children. Based on experience, ECMO is recommended for refractory septic shock in neonates and should be considered for use in children. Ongoing trials may help determine whether the promise of extracorporeal therapies translates into outcome improvement in septic children.

Abstract
The techniques of haemapheresis originated in the development of centrifugal devices separating cells from plasma and later on plasma from cells. Subsequently membrane filtration was developed allowing for plasma-cell separation. The unspecificity of therapeutic plasma exchange led to the development of secondary plasma separation technologies being specific, semi-selective or selective such as adsorption, filtration or precipitation. In contrast on-line differential separation of cells is still under development. Whereas erythrocytapheresis, granulocytapheresis, lymphocytapheresis and stem cell apheresis are technically advanced, monocytapheresis may need further improvement. Also, indications such as erythrocytapheresis for the treatment of polycythaemia vera or photopheresis though being clinically effective and of considerable importance for an appropriate disease control are to some extent under debate as being either too costly or without sufficient understanding of the mechanism. Other forms of cell therapy are under development. Rheohaemapheresis as the most advanced technology of extracorporeal haemorheotherapy is a rapidly developing approach contributing to the treatment of microcirculatory diseases and tissue repair. Whereas the control of a considerable number of (auto-) antibody mediated diseases is beyond discussion, the indication of apheresis therapy for immune complex mediated diseases is quite often still under debate. Detoxification for artificial liver support advanced considerably during the last years, whereas conclusions on the efficacy of septicaemia treatment are debatable indeed. LDL-apheresis initiated in 1981 as immune apheresis is well established since 24 years, other semi-selective or unspecific procedures, allowing for the elimination of LDL-cholesterol among other plasma components are also being used. Correspondingly Lp(a) apheresis is available as a specific, highly efficient elimination procedure superior to techniques which also eliminate Lp(a). Quality control systems, more economical technologies as for instance by increasing automation, influencing the over-interpretation of evidence based medicine especially in patients with rare diseases without treatment alternative, more insight into the need of controlled clinical trials or alternatively improved diagnostic procedures are among others tools ways to expand the application of haemapheresis so far applied in cardiology, dermatology, haematology, immunology, nephrology, neurology, ophthalmology, otology, paediatrics, rheumatology, surgery and transfusion medicine.

Abstract
Despite the commonly accepted indications for hemodialysis and extracorporeal depuritive techniques, some clinicians have come to rely on blood purification for clinical states where the targeted substance for removal differs from uremic waste products. Over the last decade, a number of studies have emerged to help define the application of extracorporeal blood purification (ECBP) to these "nonuremic" indications. This review describes the application of extracorporeal blood purification in clinical states including sepsis, rhabdomyolysis, congestive heart failure, hepatic failure, tumor lysis syndrome, adult respiratory distress syndrome, intravenous contrast exposure, and lactic acidosis. Additional comments are provided to review existing literature on thermoregulation and osmoregulation, including acute brain injury.

Abstract
Acute renal failure (ARF) is uncommon in childhood and there is little consensus on the appropriate treatment modality when renal replacement therapy is required. Members of the European Pediatric Peritoneal Dialysis Working Group have produced the following guidelines in collaboration with nursing staff. Good practice requires early discussion of patients with ARF with pediatric nephrology staff and transfer for investigation and management in those with rapidly deteriorating renal function. Patients with ARF as part of multi-organ failure will be cared for in pediatric intensive care units where there should be access to pediatric nephrology support and advice. The choice of dialysis therapy will therefore depend upon the clinical circumstances, location of the patient, and expertise available. Peritoneal dialysis has generally been the preferred therapy for isolated failure of the kidney and is universally available. Intermittent hemodialysis is frequently used in renal units where nursing expertise is available and hemofiltration is increasingly employed in the intensive care situation. Practical guidelines for and the complications of each therapy are discussed.

Abstract
BACKGROUND/AIMS Cytokines play important roles in the pathophysiology of systemic inflammatory response syndrome (SIRS) and sepsis. Therefore, some effective measures to remove cytokines from the bloodstream could be effective in the treatment of SIRS and sepsis. The aim of this study was to evaluate the cytokine adsorptive property of various adsorbents for the purpose of the development of new selective cytokine adsorption columns. METHODS The cytokine adsorptive property of adsorbent in a CF-X column, which consists of cellulose beads cross-linked with hexamethylene-di-isocyanate, was compared with those of various adsorbents in currently available immunoadsorption columns, such as Immusorba TR, Immusorba PH, Selesorb, and Lixelle, in vitro batchwise test using patients' plasma. A newly developed adsorbent, MPCF-X, which was modified by coating the surface of the adsorbent in CF-X with 2-methacryloyloxyethyl phosphorylcholine (MPC), was also tested for its cytokine adsorptive property. RESULTS The adsorbent in CF-X showed a significantly higher adsorption rate for TNF-alpha, interleukin (IL)-6 and IL-10 compared with other adsorbents (p < 0.05). Adsorbent in Lixelle showed good affinity to TNF-alpha and IL-8. Especially, the adsorbent in CF-X almost completely removed TNF-alpha, whereas it also had considerable affinity to normal IgG. MPCF-X showed decreased affinity to IgG with considerable adsorptive properties to cytokines. CONCLUSION Selective cytokine adsorption columns could be developed with improvement of currently available adsorbents. Such a new selective cytokine adsorption column could be clinically applied for the treatment of SIRS/sepsis.

Abstract
Despite recent therapeutic advances, mortality due to septic shock remains high. The most important causes of mortality are refractory shock, uncontrollable alterations of coagulation, and multiorgan failure. Some authors have proposed the early use of plasmafiltration and high flow hemodiafiltration for refractory septic shock. Most authors initiate treatment with a short session of plasmafiltration followed by continuous hemodiafiltration. A 13-year-old girl presented refractory meningococcal septic shock, disseminated intravascular coagulation, and acute renal failure unresponsive to volume expansion and high doses of adrenalin and noradrenaline. She received simultaneous treatment with plasmafiltration and continuous venovenous hemodiafiltration for 30 hours. Two pumps of extrarenal purification placed in parallel through the same double line catheter were used. Fast hemodynamic stabilization and control of the coagulopathy were achieved. The patient survived with progressive recovery of renal function but required amputation of the inferior left limb. Continuous plasmafiltration and venovenous hemodiafiltration can be used simultaneously for the treatment of older children with septic shock, severe coagulopathy, and hypervolemia.
