RESUMO
INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic represented a global public health problem with devastating consequences that have challenged conventional medical treatments. Continuous renal replacement therapy (CRRT), based on a spectrum of modalities and dialysis membranes, can modify cytokine storms, and improve the clearance of inflammatory factors. As severe COVID-19 can lead to acute kidney injury (AKI) requiring RRT, most patients require more than one extracorporeal organ support at this point. This is due to complications that lead to organ dysfunction. The aim of our study was to assess renal recovery and survival while use of the oXiris membrane, as well as a decrease in vasopressors and hemodynamic parameters. METHODS: This was a retrospective, observational study. The population included adult patients (aged >18 years) with a real-time PCR COVID-19 positive test, admitted to the intensive care unit (ICU) with AKI KDIGO 3, which required CRRT, in a hospital in northern Mexico. The primary outcomes were renal recovery and survival, and the secondary outcomes were a decrease in the vasopressor requirements and changes in the hemodynamic parameters. RESULTS: Thirteen patients were included from January 2020 to August 2021, all of whom met the inclusion criteria. oXiris, an AN69-modified membrane, was used for blood purification and cytokine storm control in all the patients. The primary outcome, renal recovery, and survival were observed in 23% of the patients. The secondary outcome was a decrease of 12% in the use of noradrenaline in the first 24 h of CRRT initiation with oXiris, in addition to a decrease in creatinine and C-reactive protein levels in all patients. DISCUSSION: The use of the oXiris membrane in patients with severe COVID-19 improved hemodynamic parameters, with 23% of the patients achieving renal recovery. The decrease on the requirement of vasopressors in the overall patients in the first 24 h of CRRT with oXiris was achieved. The mean decrease was of 12%, accompanied by a decrease in inflammatory markers. There is literature on the benefit of CRRT with a modified AN69 membrane in Mexico; however, studies in this regard are scarce, and our research provides valuable information on our experience in this field.

OBJECTIVE: To assess the outcome of patients with cancer-related sepsis requiring continuous renal replacement therapy (CRRT) in a single-center pediatric intensive care unit (PICU). METHOD: Children with sepsis who necessitate CRRT from January 2017 to December 2021 were enrolled. The patients with leukemia/lymphoma or solid tumors were defined as underlying cancer. Multivariate logistic regression analysis was performed to identify the death risk factors in patients with cancer-related sepsis. RESULTS: A total of 146 patients were qualified for inclusion. Forty-six (31.5%) patients with cancer-related sepsis and 100 (68.5%) non-cancer-related sepsis. The overall PICU mortality was 28.1% (41/146), and mortality was significantly higher in cancer-related sepsis patients compared with non-cancer patients (41.3% vs. 22.0%, p = 0.016). Need mechanical ventilation, p-SOFA, acute liver failure, higher fluid overload at CRRT initiation, hypoalbuminemia, and high inotropic support were associated with PICU mortality in cancer-related sepsis patients. Moreover, levels of IL-6, total bilirubin, creatinine, blood urea nitrogen, and international normalized ratio were significantly higher in non-survivors than survivors. In multivariate logistic regression analysis, pediatric sequential organ failure assessment (p-SOFA) score (OR:1.805 [95%CI: 1.047-3.113]) and serum albumin level (OR: 0.758 [95%CI: 0.581 -0.988]) were death risk factors in cancer-related sepsis receiving CRRT, and the AUC of combined index of p-SOFA and albumin was 0.852 (95% CI: 0.730-0.974). CONCLUSION: The overall PICU mortality is high in cancer-related sepsis necessitating CRRT. Higher p-SOFA and lower albumin were independent risk factors for PICU mortality.

BACKGROUND: Continuous renal replacement therapy (CRRT) support is crucial for critically ill patients and it is underexplored in specific situations. Experimental CRRT offers a means to gain insights into these scenarios, but the prohibitive cost of CRRT machines limits their accessibility. This study aimed to develop and validate a low-cost and precise dialysate controller for experimental CRRT. RESULTS: Our results demonstrate a commendable level of precision in affluent flow control, with a robust correlation (R2 = 0.99) for continuous flow and a strong correlation (R2 = 0.95) for intermittent flow. Additionally, we observed acceptable agreement with a bias = 3.4 mL (upper limit 95% = 43.9 mL and lower limit 95% = - 37 mL) for continuous flow and bias = - 20.9 mL (upper limit 95% = 54 mL and lower limit 95% = - 95.7 mL) for intermittent flow, in this way, offering a precise CRRT dose for the subjects. Furthermore, we achieved excellent precision in the cumulative ultrafiltration net (UFnet), with a bias = - 2.8 mL (upper limit 95% = 6.5 mL and lower limit 95% = - 12 mL). These results remained consistent even at low affluent flow rates of 8, 12, and 20 mL/min, which are compatible with CRRT doses of 25-30 mL/kg for medium-sized animals. Moreover, the acceptable precision of our findings persisted when the dialysate controller was subjected to high filter dialysate chamber pressure for an extended duration, up to 797 min. CONCLUSIONS: The low-cost dialysate controller developed and tested in this study offers a precise means of regulating CRRT in experimental settings. Its affordability and accuracy render it a valuable instrument for studying CRRT support in unconventional clinical scenarios, particularly in middle-income countries' experimental ICU laboratories.
RESUMO
UNASSIGNED: Continuous renal replacement therapy (CRRT) is the main extracorporeal kidney support therapy used in critical ill patients in the intensive care unit (ICU). Since its conceptualization ~50 years ago, there have been major improvements in its technology and utilization. The last decade, and particularly since the COVID-19 pandemic, has been marked by a growing interest and demand of CRRT in worldwide ICUs. This has underpinned the need for improvements in nomenclature and process standardization, optimization of CRRT deliverables, and the development and validation of key performance indicators. Further, how to leverage digital health technologies to build clinical decision support for CRRT and improve personalized bedside decisions is a subject of intense investigation. Herein, we summarize notable advancements in the provision of CRRT and propose areas in need of further development. (Rev Invest Clin. 2023;75(6):348-58).

RESUMO
Extracorporeal Membrane Oxygenation (ECMO) therapy had an important role in the treatment of severe COVID-19 pneumonia, where invasive mechanical ventilation was not enough to provide correct oxygenation to various organ systems. However, there are other extracorporeal technologies, such as the Molecular Absorbent Recirculation System (MARS) and Continuous Renal Replacement Therapy (CRRT), that provide temporal support for any critical patient. The following case describes a 60-year-old man with severe Acute Respiratory Distress Syndrome (ARDS), who needed ECMO therapy. During the critical days of hospitalization, CRRT was used, but a sudden hyperbilirubinemia ensued. Consequently, MARS therapy was initiated; followed by an improvement of bilirubin levels. Additional studies are needed to establish the possible benefits of the combination of MARS therapy and ECMO; however, we detected that concomitantly, there was a decrease in other laboratory parameters such as acute phase reactants. Even though, no change in clinical course was observed, as shown in some studies.

Severe liver failure is common in Low-and-Medium Income Countries (LMIC) and is associated with a high morbidity, mortality and represents an important burden to the healthcare system. In its most severe state, liver failure is a medical emergency, that requires supportive care until either the liver recovers or a liver transplant is performed. Frequently the patient requires intensive support until their liver recovers or they receive a liver transplant. Extracorporeal blood purification techniques can be employed as a strategy for bridging to transplantation or recovery. The most common type of extracorporeal support provided to these patients is kidney replacement therapy (KRT), as acute kidney injury is very common in these patients and KRT devices more readily available. However, because most of the substances that the liver clears are lipophilic and albumin-bound, they are not cleared effectively by KRT. Hence, there has been much effort in developing devices that more closely resemble the clearance function of the liver. This article provides a review of various non-biologic extracorporeal liver support devices that can be used to support these patients, and our perspective keeping in mind the needs and unique challenges present in the LMIC of Latin America.
RESUMO
BACKGROUND: Continuous renal replacement therapy is one of the most frequently used treatments for acute kidney injury (AKI) in intensive care units (ICUs). It requires professionals with specialized knowledge, specific facilities, and care guidelines to ensure appropriate clinical practice. AIM: To validate the care guidelines for patients undergoing continuous renal replacement therapy. METHOD: This is a methodological study regarding consensual validation of the directives of care. These directives followed the formulation of the research question, a literature review, elaboration of the directive, and validation of the agreement by a committee consisting of seven expert judges. RESULTS: The data were analysed based on the content validity index and described in four categories. Among 40 care-related items, 95% showed a degree of agreement above 80% for adequacy and 82.5% showed a degree of agreement above 75% for relevance. CONCLUSION: The care-related items identified in the literature showed a high percentage of agreement among the judges and reflected the treatment requirements of these patients. RELEVANCE TO CLINICAL PRACTICE: The guideline will be important to assist in the care process regarding patient safety and quality of care.

SUMMARY OBJECTIVE: A few pediatric studies were present which focused on renal replacement therapy used for critically ill children. This research aimed to determine the ratio of utilization of intermittent hemodialysis, continuous renal replacement therapy, and peritoneal dialysis, and to study the properties and outcomes of critically ill pediatric patients who underwent renal replacement therapy. METHODS: Critically ill children admitted to the intensive care unit and received renal replacement therapy from February 2020 to May 2022 were included. The children were divided into three groups: hemodialysis, continuous renal replacement therapy, and peritoneal dialysis. RESULTS: A total of 37 patients (22 boys and 15 girls) who received renal replacement therapy met the criteria for this study. Continuous renal replacement therapy was used in 43%, hemodialysis in 38%, and peritoneal dialysis in 19%. In all, 28 (73%) children survived and 9 (27%) died in intensive care unit. The mean systolic blood pressure was significantly lower among children who received continuous renal replacement therapy (p<0.001). The need for inotropic medications and a higher PRISM III score were found to be the greatest indicators of mortality. CONCLUSION: The outcome of children receiving renal replacement therapy seems to be related to their needs for vasoactive drugs and the severity of the underlying disease in the continuous renal replacement therapy group relative to the other groups.

BACKGROUND: Anticoagulation in continuous renal replacement therapy (CRRT) is essential to counteract the coagulation cascade activation, induced by the dialysis circuit. Heparin is the most widely used anticoagulant, followed by regional citrate anticoagulation (RCA). AIM: To determine the effectiveness and safety of anticoagulant treatment with citrate in CRRT. Material and Methods: Retrospective study of adults in CRRT hospitalized between the years 2014 and 2020 in critical units, who required change to RCA according to established protocols. RESULTS: We studied 24 patients aged 63 ± 13 years (12 females). The reasons for admission were acute kidney injury (AKI) in 80% and stage 5 chronic kidney disease in 20%. The indication of RCA in 75% of patients was by coagulation of more than 3 circuits in 24 hours. The duration of the circuit in RCA was 18.5 ± 4.8 hours versus 11.9 ± 4.9 hours with heparin (p < 0.0001). There were 19 mild complications that did not affect the RCA. Conclusions: RCA is feasible to perform, it is a safe and efficient procedure if it is protocolized, allowing a longer duration of the dialysis circuit.

Sepsis is one of the leading causes of death in critically ill patients with COVID-19 and blood purification therapies have a role to immunomodulate the excessive inflammatory response and improve clinical results. One of the devices designed for these therapies is the oXiris® filter, allowing to perform renal replacement therapy combined with selective adsorption of endotoxins and cytokines. We report a 55-year-old male with COVID who developed a septic shock secondary to a sepsis caused by Pseudomona aeruginosa, refractory to the usual management. A veno-venous continuous hemofiltration was started using the oXiris® filter for 48 hours. Subsequently, there was an improvement in clinical perfusion parameters and a reduction in inflammatory markers. The patient was discharged from the intensive care one month later.

Acute brain injury is the sudden and reversible loss of brain self regulation capacity as a disruption of the blood-brain barrier that conditions metabolic and inflammatory disorders that can exacerbate acute kidney injury in a critical setting; specifically it has been described that the alterations of the internal environment that come from the severity of the acute kidney injury increases the risk of endocranial hypertension and cerebral edema; in this context, injuries should be identified and treated in a timely manner with a comprehensive approach. Continuous renal replacement therapy is an extracorporeal purification technique that has been gaining ground in the management of acute kidney injury in critically ill patients. Within its modalities, continuous venous venous hemofiltration is described as the therapy of choice in patients with acute brain injury due to its advantages in maintaining hemodynamic stability and reducing the risk of cerebral edema. Optimal control of variables such as timing to start renal replacement therapy, the prescribed dose, the composition of the replacement fluid and the anticoagulation of the extracorporeal circuit will have a significant impact on the evolution of the neurocritical patient with acute kidney injury. There are limited studies evaluating the role of hemofiltration in this context.
RESUMO
Background and aim: The knowledge about the acute kidney injury (AKI) incidence in patients with coronavirus disease 2019 (COVID-19) can help health teams to carry out a targeted care plan. This study aimed to determine the AKI incidence in patients hospitalized with COVID-19. Methods: The electronic search covered research published until June 20, 2020, and included five databases, PubMed, Embase, Web of Science, Scopus, and Lilacs (Latin American and Caribbean Health Sciences Library). Eligible studies were those including data from AKI occurrence in adult patients hospitalized with COVID-19. The primary outcome was AKI incidence, and the secondary outcome assessed was the AKI mortality. Additionally, the estimated incidence of renal replacement therapy (RRT) need also was verified. Using a standardized form prepared in Microsoft Excel, data were extracted by two independents authors, regarding the description of studies, characteristics of patients and clinical data on the AKI occurrence. Results: We included 30 studies in this systematic review, of which 28 were included in the meta-analysis. Data were assessed from 18.043 adult patients with COVID-19. The AKI estimate incidence overall and at the ICU was 9.2% (4.6-13.9) and 32.6% (8.5-56.6), respectively. AKI estimate incidence in the elderly patients and those with acute respiratory disease syndrome was 22.9% (-4.0-49.7) and 4.3% (1.8-6.8), respectively. Patients with secondary infection, AKI estimate incidence was 31.6% (12.3-51.0). The estimate incidence of patients that required RRT was 3.2% (1.1-5.4) and estimate AKI mortality was 50.4% (17.0-83.9). Conclusion: The occurrence of AKI is frequent among adult patients hospitalized with COVID-19, and affects on average, up to 13.9% of these patients. It is believed that AKI occurs early and in parallel with lung injury.
Antecedentes y objetivo: El conocimiento de la incidencia de lesión renal aguda (LRA) en pacientes con enfermedad por coronavirus 2019 (COVID-19) puede ayudar a los equipos de atención médica a llevar a cabo un plan de atención específico. Este estudio tuvo como objetivo determinar la incidencia de LRA en pacientes hospitalizados con COVID-19. Métodos: La búsqueda electrónica cubrió la investigación publicada hasta el 20 de junio del 2020 e incluyó 5 bases de datos: PubMed, Embase, Web of Science, Scopus y Lilacs (Biblioteca de Ciencias de la Salud de América Latina y el Caribe). Los estudios elegibles fueron aquellos que incluyeron datos sobre la aparición de LRA en pacientes adultos hospitalizados con COVID-19. El resultado primario fue la incidencia de LRA y el resultado secundario evaluado fue la mortalidad por LRA. Además, también se verificó la incidencia estimada de necesidad de terapia de reemplazo renal (TRR). Mediante un formulario estandarizado elaborado en Microsoft Excel, los datos fueron extraídos por 2 autores independientes, haciendo referencia a la descripción de los estudios, las características de los pacientes y los datos clínicos sobre la ocurrencia de LRA. Resultados: En esta revisión sistemática se incluyeron 30 estudios, de los cuales 28 se incluyeron en el metaanálisis. Se evaluaron los datos de 18.043 pacientes adultos con COVID-19. La incidencia estimada de LRA en general y en la UCI fue del 9,2% (4,6-13,9) y del 32,6% (8,5-56,6), respectivamente. La incidencia estimada de LRA en pacientes ancianos y pacientes con síndrome de enfermedad respiratoria aguda fue del 22,9% (4,0-49,7) y del 4,3% (1,8-6,8), respectivamente. En pacientes con infección secundaria, la incidencia estimada de LRA fue del 31,6% (12,3-51,0). La incidencia estimada de pacientes que requirieron TRR fue del 3,2% (1,1-5,4) y la mortalidad estimada por LRA fue del 50,4% (17,0-83,9). Conclusión: La ocurrencia de LRA es frecuente en pacientes adultos hospitalizados con COVID-19 y afecta, en promedio, hasta al 13,9% de estos pacientes. Se cree que la LRA ocurre temprano y en paralelo con la lesión pulmonar.

RESUMEN La insuficiencia renal aguda es definida como la pérdida de función del riñón ocasionada por diversas causas, entre ellas infección e ingesta de fármacos. Esta entidad tiene alta morbilidad y mortalidad en las unidades de cuidados críticos. El tratamiento de la misma va desde la propia protección renal hasta la sustitución artificial de las funciones del riñón lesionado. En la actualidad la terapia de reemplazo renal continua se ha utilizado como soporte renal, y ofrece mayor estabilidad clínica a los pacientes más inestables. En esta revisión se comentan conceptos, indicaciones y los más recientes estudios que validan el uso de esta terapéutica, así como el método de programación que se utilizó en un paciente con diagnóstico de una leptospirosis icterohemorrágica (síndrome de Weil), que estuvo en shock séptico con disfunción multiorgánica, donde se empleó esta terapia con resultados satisfactorios (AU).
ABSTRACT Acute kidney failure is defined as the loss of kidney function caused by various causes, including infection and drug intake. This entity has high morbidity and mortality in critical care units. Treatment ranges from renal protection to artificial replacement of the functions of the injured kidney. Currently, continuous renal replacement therapy has been used as renal support, and offers greater clinical stability to the most unstable patients. In this review, authors discuss concepts, indications and the most recent studies that validate the use of this therapeutic, as well as the programming method that was used in a patient with diagnosis of icteric-hemorrhagic leptospirosis (Weil syndrome), who was in septic shock with multiorgan dysfunction, where this therapy was used with satisfactory results (AU).

BACKGROUND: Coronavirus disease 2019 (COVID-19) may predispose patients to thrombotic events. The best anticoagulation strategy for continuous renal replacement therapy (CRRT) in such patients is still under debate. The purpose of this study was to evaluate the impact that different anticoagulation protocols have on filter clotting risk. METHODS: This was a retrospective observational study comparing two different anticoagulation strategies (citrate only and citrate plus intravenous infusion of unfractionated heparin) in patients with acute kidney injury (AKI), associated or not with COVID-19 (COV + AKI and COV - AKI, respectively), who were submitted to CRRT. Filter clotting risks were compared among groups. RESULTS: Between January 2019 and July 2020, 238 patients were evaluated: 188 in the COV + AKI group and 50 in the COV - AKI group. Filter clotting during the first filter use occurred in 111 patients (46.6%). Heparin use conferred protection against filter clotting (HR = 0.37, 95% CI 0.25-0.55), resulting in longer filter survival. Bleeding events and the need for blood transfusion were similar between the citrate only and citrate plus unfractionated heparin strategies. In-hospital mortality was higher among the COV + AKI patients than among the COV - AKI patients, although it was similar between the COV + AKI patients who received heparin and those who did not. Filter clotting was more common in patients with D-dimer levels above the median (5990 ng/ml). In the multivariate analysis, heparin was associated with a lower risk of filter clotting (HR = 0.28, 95% CI 0.18-0.43), whereas an elevated D-dimer level and high hemoglobin were found to be risk factors for circuit clotting. A diagnosis of COVID-19 was marginally associated with an increased risk of circuit clotting (HR = 2.15, 95% CI 0.99-4.68). CONCLUSIONS: In COV + AKI patients, adding systemic heparin to standard regional citrate anticoagulation may prolong CRRT filter patency by reducing clotting risk with a low risk of complications.

Introduction: The kidney may be affected by coronavirus (COVID-19) in the setting of acute kidney injury (AKI). Data about AKI in intensive care unit (ICU) patients in Latin America are scarce. We aimed to evaluate the risk of AKI, dialysis (HD), and death in ICU COVID-19 patients in a Brazilian center. Methods: Analysis from medical records of COVID-19 patients in a Brazilian center. Results: A total of 95 patients were analyzed. There was male predominance (64.2%), median age: 64.9 years, and previous history of hypertension and diabetes in 51.6 and 27.4%, respectively. AKI was diagnosed in 54 (56.8%) patients, and 32 (59.2%) of them required HD. Mortality rate was 17.9%. AKI patients when compared with no-AKI were more frequently hypertensive/diabetic and more often needed organ support therapies. Workups depicted more anemia, lymphopenia, and higher levels of inflammatory markers and higher mortality. Comparing patients who had undergone death to survivors, they were older, more frequently diabetic, and had worse SAPS3 and SOFA scores and need for organ support therapies, AKI, and HD. Multinomial logistic regression revealed that hypertension (p = 0.018) and mechanical ventilation (p = 0.002) were associated with AKI; hypertension (p = 0.002), mechanical ventilation (p = 0.008), and use of vasopressor (p = 0.027) to HD patients; and age >65 years (p = 0.03) and AKI (p = 0.04) were risk factors for death. Conclusions: AKI was a common complication of ICU COVID-19 patients, and it was more frequent in patients with hypertension and need of organ support therapies. As well as age >65 years, AKI was an independent risk factor for death.
RESUMO
Acute kidney injury (AKI) is common in critically ill patients, and renal replacement therapy (RRT) constitutes an important aspect of acute management during critical illness. Continuous RRT (CRRT) is frequently utilized in intensive care unit settings, particularly in patients with severe AKI, fluid overload, and hemodynamic instability. The main goal of CRRT is to timely optimize solute control, acid-base, and volume status. Total effluent dose of CRRT is a deliverable that depends on multiple factors and therefore should be systematically monitored (prescribed vs. delivered) and iteratively adjusted in a sustainable mode. In this manuscript, we review current evidence of CRRT dosing and provide recommendations for its implementation as a quality indicator of CRRT delivery.
