Acharya M, Berger R, Popov AF. The role of the ADVanced Organ Support (ADVOS) system in critically ill patients with multiple organ failure. Artif Organs 2022; 46:735-746. [PMID: 35128695 PMCID: PMC9306712 DOI: 10.1111/aor.14188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/03/2022] [Accepted: 01/19/2022] [Indexed: 11/30/2022]
Abstract
Background Multi‐organ failure characterized by acute kidney injury, liver dysfunction, and respiratory failure is a complex condition associated with high mortality, for which multiple individual support devices may be simultaneously required. This review aims to appraise the current evidence for the ADVanced Organ Support (ADVOS) system, a novel device integrating liver, lung, and kidney support with blood detoxification. Methods We performed a literature review of the PubMed database to identify human and animal studies evaluating the ADVOS system. Results In porcine models of acute liver injury and small clinical studies in humans, ADVOS significantly enhanced the elimination of water‐soluble and protein‐bound toxins and metabolites, including creatinine, ammonia, blood urea nitrogen, and lactate. Cardiovascular parameters (mean arterial pressure, cerebral perfusion pressure, and cardiac index) and renal function were improved. ADVOS clears carbon dioxide (CO2) effectively with rapid correction of pH abnormalities, achieving normalization of CO2, and bicarbonate levels. In patients with COVID‐19 infection, ADVOS enables rapid correction of acid–base disturbance and respiratory acidosis. ADVOS therapy reduces mortality in multi‐organ failure and has been shown to be safe with minimal adverse events. Conclusions From the small observational studies analyzed, ADVOS demonstrates excellent detoxification of water‐soluble and protein‐bound substances. In particular, ADVOS permits the correction of metabolic and respiratory acidosis through the fluid‐based direct removal of acid and CO2. ADVOS is associated with significant improvements in hemodynamic and biochemical parameters, a trend toward improved survival in multi‐organ failure, and is well‐tolerated. Larger randomized trials are now necessary to further validate these encouraging results.

Non-neurologic organ dysfunction plays a major role in predicting outcomes in pediatric traumatic brain injury. J Pediatr Surg 2020; 55:1590-1595. [PMID: 32081358 DOI: 10.1016/j.jpedsurg.2020.01.051] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 12/02/2019] [Accepted: 01/24/2020] [Indexed: 10/25/2022]
Abstract
BACKGROUND Nonneurological organ dysfunction (NNOD) occurs after traumatic brain injury (TBI) and is associated with mortality. The aim of our study was to evaluate the prevalence of NNOD and its association with outcomes in pediatric patients with TBI. We hypothesized that NNOD is associated with worse outcomes in pediatric patients with severe TBI. METHODS We performed a 4-year (2013-16) analysis of our prospectively maintained TBI database. All patients (age < 18) with an isolated-severe TBI (head-abbreviated injury scale: AIS ≥ 3 & extracranial-AIS < 3) were included. NNOD was measured using the pediatric multiple organ dysfunction (P-MOD) score. Outcomes were in-hospital mortality, Glasgow Outcome Scale-Extended (GOS-E), and adverse discharge disposition: rehabilitation or skilled nursing facility (SNF). Regression analysis was performed. RESULTS We analyzed 292 patients. Mean age was 11 ± 6 years, 57% were male and the mortality rate was 18.1%. The incidence of NNOD was 35%. The most common dysfunctional organ system was the respiratory (25%) followed by the cardiovascular (12%). On regression analysis, the presence of at least one NNOD was independently associated with in-hospital mortality (OR 2.1 [1.7-2.9]; p < 0.01), low GOS-E (OR 1.8 [1.5-2.3]; p < 0.01), and SNF disposition (OR 1.7 [1.2-2.1]; p < 0.01). CONCLUSION NNOD develops in one of every three severe TBI pediatric patients and is independently associated with adverse outcomes. Identification of NNOD in pediatric TBI and focusing on management of NNOD could improve outcomes. LEVEL OF EVIDENCE III Prognostic.

[PMID: 31122276 PMCID: PMC6533687 DOI: 10.1186/s13054-019-2459-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 04/26/2019] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Multiple organ dysfunction is a common cause of morbidity and mortality in intensive care units (ICUs). Original development of the Sequential Organ Failure Assessment (SOFA) score was not to predict outcome, but to describe temporal changes in organ dysfunction in critically ill patients. Organ dysfunction scoring may be a reasonable surrogate outcome in clinical trials but further exploration of the impact of case mix on the temporal sequence of organ dysfunction is required. Our aim was to compare temporal changes in SOFA scores between hospital survivors and non-survivors. METHODS We performed a population-based observational retrospective cohort study of critically ill patients admitted from January 1, 2004, to December 31, 2013, to 4 multisystem adult intensive care units (ICUs) in Calgary, Canada. The primary outcome was temporal changes in daily SOFA scores during the first 14 days of ICU admission. SOFA scores were modeled between hospital survivors and non-survivors using generalized estimating equations (GEE) and were also stratified by admission SOFA (≤ 11 versus > 11). RESULTS The cohort consisted of 20,007 patients with at least one SOFA score and was mostly male (58.2%) with a median age of 59 (interquartile range [IQR] 44-72). Median ICU length of stay was 3.5 (IQR 1.7-7.5) days. ICU and hospital mortality were 18.5% and 25.5%, respectively. Temporal change in SOFA scores varied by survival and admission SOFA score in a complicated relationship. Area under the receiver operating characteristic (ROC) curve using admission SOFA as a predictor of hospital mortality was 0.77. The hospital mortality rate was 5.6% for patients with an admission SOFA of 0-2 and 94.4% with an admission SOFA of 20-24. There was an approximately linear increase in hospital mortality for SOFA scores of 3-19 (range 8.7-84.7%). CONCLUSIONS Examining the clinical course of organ dysfunction in a large non-selective cohort of patients provides insight into the utility of SOFA. We have demonstrated that hospital outcome is associated with both admission SOFA and the temporal rate of change in SOFA after admission. It is necessary to further explore the impact of additional clinical factors on the clinical course of SOFA with large datasets.

Abstract
OBJECTIVES Changes in lipid profiles occur in systemic inflammatory response syndrome (SIRS), whether due to sepsis or another cause. Hypocholesterolemia associated with hypertriacylglycerolemia can lead to disease severity and higher mortality. The aim of this systematic review was to describe the principal alterations in markers that participate in the alteration of the lipid profile. METHODS We reviewed articles focused on alterations in the lipid profile in SIRS, sepsis, or both that were indexed in the Scientific Electronic Library Online from 2000 to 2017. The descriptors used were SIRS; sepsis; lipid profile; and lipoproteins. We focused in particular on the relationships among SIRS, sepsis, and lipid profiles. RESULTS We included 29 studies that discussed decreased high-density lipoprotein (HDL), total cholesterol, and low-density lipoprotein, and elevated triacylglycerols concentrations in patients with SIRS, sepsis, or both. The variation in the lipid profile was proportional to the level of inflammation as evaluated by inflammatory markers, including C-reactive protein, interleukin-6 and interleukin-8, lipopolysaccharide-binding protein, and tumor necrosis factor. Additionally, there was a change in the composition of lipoproteins, especially HDL, triacylglycerols, and very low-density lipoprotein. HDL appears to be an inflammatory marker, as reduction of its levels reflects the intensity of the underlying inflammatory process. CONCLUSION Critically ill patients with SIRS, sepsis, or both presented with alterations in lipid metabolism.

Abstract
The production of hyperlactatemia in the critically ill patient has previously been thought to be primarily related to anaerobic conditions. Newer data suggests that lactate accumulates under aerobic conditions in clinical settings that were previously thought to solely represent anaerobic processes. This review summarizes the present understanding of lactate metabolism and reviews the data supporting use of lactate determinations in the critical care setting. The use of lactate as a marker of inadequate tissue perfusion as well as its role as a prognostic indicator are discussed. The utility of managing lactic acidosis with various buffers is also reviewed.

Abstract
The purpose of this study was to determine the mortality rate in 527 critically ill patients with multiple organ failure (MOF), treated in our ICU between August, 1986 and January, 1992, and to compare it with the results obtained in a group of patients studied who had been treated between October, 1978 and July, 1986. The relationship between the mortality rate and each type of organ failure and the extent of organ system involvement was also investigated. The overall mortality rate was 25%, and the rate increased with the number of failed organs. Sepsis and disseminated intravascular coagulation were closely associated with the development of MOF. The mortality rate of patients with the failure of two organs in the present study was significantly lower than that found in those in the previous study. Although artificial organ mechanical life support technology other than that for patients with renal failure is still unsatisfactory, these results suggest that the prognosis of patients with MOF is improving.

Abstract
OBJECTIVE To describe the incidence of non-neurologic organ dysfunction and its association with outcome in patients with severe traumatic brain injury admitted to intensive care. DESIGN Observational cohort study. SETTING Foothills Medical Centre, which is the only neurosurgical service in southern Alberta (population approximately 1.3 million). PATIENTS Patients were 209 consecutive patients with severe traumatic brain injury. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Non-neurologic organ dysfunction was measured by the maximum modified multiple organ dysfunction score. Organ system failure was defined as a component score of >/=3 on any day during the patient's intensive care unit stay. One hundred and eighty-five patients (89%) developed dysfunction of at least one non-neurologic organ system. Ninety-six organ system failures were identified in 74 patients (35%). Respiratory failure was the most common non-neurologic organ system failure, occurring in 23% of patients, whereas cardiovascular failure occurred in 18%. Eight patients (4%) had failure of the coagulation system. One patient had renal failure, whereas no patient developed hepatic failure. In a multivariate model, non-neurologic organ dysfunction was independently associated with hospital mortality (odds ratio for hospital mortality, 1.63; 95% confidence interval, 1.34, 1.98 for one maximum modified multiple organ dysfunction score point). Non-neurologic organ dysfunction was also independently associated with dichotomized Glasgow Outcome Score, as a measure of neurologic outcome (odds ratio for unfavorable neurologic outcome, 1.53; 95% confidence interval, 1.22, 1.98 for one maximum modified multiple organ dysfunction score point). The timing of the organ dysfunction did not appear to be important in the prediction of outcome. CONCLUSIONS Non-neurologic organ dysfunction is common in patients with severe traumatic brain injury and is independently associated with worse outcome.

Abstract
OBJECTIVE Multiple organ dysfunction is a common cause of death in intensive care units. We describe the daily course of multiple organ dysfunction measured by the Sequential Organ Failure Assessment score in a population-based cohort of critically ill patients. DESIGN Prospective cohort study. SETTING Adult multisystem intensive care units in the Calgary Health Region. PATIENTS A total of 1,436 patients admitted from May 1, 2000 to April 30, 2001. MEASUREMENTS Temporal change in Sequential Organ Failure Assessment score. INTERVENTIONS None; observational study. MAIN RESULTS The mean age was 58 yrs (range, 14-100). The mean +/- sd intensive care unit admission Acute Physiology and Chronic Health Evaluation II score was 25 +/- 9. The median intensive care unit length of stay was 4 days (interquartile range, 2-8), and the median hospital length of stay was 15 days (interquartile range, 7-32). A total of 20.5% of patients were infected at admission, and 26.0% were immediately postoperative. Intensive care unit mortality was 27.0%, and hospital mortality was 35.1%. The daily Sequential Organ Failure Assessment score was significantly higher in nonsurvivors than survivors. A population-averaged model determined a mean rate of change of Sequential Organ Failure Assessment score to be -0.29 per day (95% confidence interval, -0.32 to -0.25) for survivors and -0.03 per day (95% confidence interval, -0.08 to 0.03) for nonsurvivors (overall regression, p <.0001). Patients with infection had higher admission Sequential Organ Failure Assessment scores compared with patients without infection (difference, 1.8; p <.001), but a similar rate of daily change. CONCLUSIONS Multiple organ dysfunction, does not follow a course of progressive and sequential failure. Evidence of differential daily change should further inform the use of organ failure scores as surrogate outcomes in clinical trials.

Abstract
OBJECTIVE Jejunal nitric oxide (NO) formation is impaired during mucosal hypoperfusion. This study was undertaken to investigate whether this phenomenon could result from a restricted mucosal availability of NO-synthase substrates, ie, oxygen and/or L-arginine. DESIGN Controlled study using laboratory animals. SETTING University animal research laboratory. SUBJECTS Eighteen chloralose-anesthetized, ventilated, juvenile Landrace domestic pigs. INTERVENTIONS Mesenteric hypoperfusion was induced by intrapericardial infusion of Ringer's solution to achieve decreased cardiac output by creation of cardiac tamponade. MEASUREMENTS AND MAIN RESULTS Animals were prepared for jejunal intraluminal perfusion with 150 mM NaCl or 3 mM L-arginine solution in an isolated intestinal segment and then subjected to cardiac tamponade. Jejunal mucosal NO formation was measured with a tonometric technique. Mesenteric blood flow was measured as portal blood flow, and mucosal perfusion was measured by laser Doppler flowmetry. Regional oxygen consumption and delivery were calculated from arterial and portal blood samples. Cardiac tamponade reduced jejunal NO formation (-52%), mesenteric oxygen delivery (-75%), oxygen consumption (-39%), and mucosal perfusion (-43%). Oxygenation of the jejunal intraluminal perfusate completely restored the intestinal NO levels within 30 mins, whereas presence of L-arginine was without effect. CONCLUSIONS The study indicates that oxygen rather than L-arginine is the rate-limiting factor for mucosal NO production during acute reduced splanchnic perfusion.

Abstract
OBJECTIVE To study the use of emergency department (ED) femoro-femoral cardiopulmonary bypass (CPB) in the resuscitation of medical cardiac arrest patients. DESIGN Prospective, uncontrolled trial. SETTING Urban academic ED staffed with board-certified emergency physicians (EPs). PARTICIPANTS Ten patients with medical cardiac arrest unresponsive to standard therapy. INTERVENTIONS Femoro-femoral CPB instituted by EPs. RESULTS The time of cardiac arrest prior to CPB (mean+/-SD) was 32.0+/-13.6 min. The cardiac output while on CPB was 4.09+/-1.03 L/min with an average of 229+/-111 min on bypass. All 10 patients had resumption of spontaneous cardiac activity while on CPB. Seven of these were weaned from CPB with intrinsic spontaneous circulation. Of these, six patients were transferred from the ED to the operating room for cannula removal and vessel repair while the other patient died in the ED soon after discontinuing CPB. Mean survival was 47.8+/-44.7 h in the six patients leaving the ED. Although these patients had successful hemodynamic resuscitation, there were no long-term survivors. CONCLUSION CPB instituted by EPs is feasible and effective for the hemodynamic resuscitation of cardiac arrest patients unresponsive to advanced cardiac life support therapy. Future efforts need to focus on improving long-term outcome.

Abstract
OBJECTIVES To compare the outcomes for patients with one or more organ system failures treated in 1988 to 1990 with those outcomes from 1979 to 1982; to document risk factors for developing organ system failure; and investigate the relationship of these factors to hospital survival. DESIGN Prospective, multicenter, inception cohort analysis. SETTING Sixty intensive care units (ICUs) at 53 U.S. hospitals. PATIENTS A total of 17,440 ICU admissions treated in 1988 to 1990 and 5,677 ICU admissions treated in 1979 to 1982. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS At the time of organ system failure, patients were classified by demographic, physiologic, and diagnostic information. The type and number of organ system failures and physiologic responses were recorded for < or = 7 days of ICU treatment, and all patients were followed for status at hospital discharge. Hospital survival and the prognostic value of assessing the number of organ system failures were compared with risk assessment, based on use of a prognostic scoring system that estimated the patient's probability of hospital mortality. The incidence of organ system failure (48%) among patients treated in 1988 to 1990 was similar (44%) to the occurrence rate in patients in 1979 to 1982; and an identical proportion (14%) developed multiple organ system failure. There was a significant (p < .0003) improvement in hospital mortality for patients with three or more organ system failures on day 4 or later of organ system failure. However, overall hospital mortality rates from multiple organ system failure were not different over this 8-yr period. The most important predictor of hospital mortality was the severity of physiologic disturbance on the initial day of failure. Discrimination of patients by risk of hospital mortality was better using the prognostic scoring system on day 1 of organ system failure (receiver operating characteristic curve = 0.88) than using a model based on the number of organ system failures (receiver operating characteristic curve = 0.68). CONCLUSIONS Organ system failure remains a major contributor to death in patients in ICUs. The incidence and overall outcome have not significantly changed over the past 8 yrs, but there has been significant improvement in survival for patients with persistent severe organ system failure. A continuous measure of individual patient severity of illness is a more sensitive and accurate method for describing patients and estimating outcome than counting the number of organ system failures.

Abstract
Septic encephalopathy occurs easily in many septic persons. Manifestations are largely similar to those seen in other metabolic brain diseases.
