Abstract Objective. Upper gastrointestinal bleeding is a common complication in adults treated with veno-arterial Extracorporeal Membrane Oxygenation (VA-ECMO) for refractory cardiogenic shock or cardiac arrest. We aimed to determine risk factors, prevalence and outcomes associated with upper gastrointestinal bleeding (UGIB) in adult patients under VA-ECMO.Design. We conducted a retrospective cohort study (2014-2017) on consecutive VA-ECMO patients.Setting. Medical and Infectious Disease intensive care unit of university hospital Bichat-Claude Bernard in Paris, France.Patients. UGIB was defined as 1) an overt bleeding (hematemesis, melena, hematochezia), or 2) acute anemia associated with a lesion diagnosed on upper gastrointestinal endoscopy. Cause-specific models were used to identify factors associated with UGIB and death, respectively.Measurements and Main Results. 257 patients were included, of whom 48 (19%) were diagnosed with UGIB after a median of 18 [7; 43] days following cannulation; median SAPS II was 59 [43; 76]. 100 (39%) patients were implanted after cardiac surgery. Mortality occurred in 31 (65%) patients with UGIB and 121 (58%) patients without. UGIB patients had longer ICU stays (41 [19; 82] vs. 15 [6; 26]; p<.01), longer ECMO (10.5 [7; 15] vs 6 [3; 10]; p <.01) and mechanical ventilation durations (31 [18; 45] vs. 9 [5; 18]; p <.01) in days, as compared to non-UGIB patients. Ninety-nine upper gastrointestinal endoscopies (UGE) were performed and the most frequent lesions detected were gastro-duodenal ulcers (n=28, 28%), leading to 12/99 therapeutic procedures. Neither antiplatelet therapy prior to ICU admission nor a history of peptic ulcer were associated with UGIB in univariate analysis. By multivariate analysis (table), a BMI (body mass index) > 30 kg/m2 (Cause-specific hazard ratio (CSHR) [95% CI]): 3.06 [1.56; 5.98]), and extracorporeal cardiopulmonary resuscitation (ECPR) (CSHR 2.34 [1.03; 5.35]) were independently associated with an increased risk of UGIB. Conclusions. In adult patients under VA-ECMO, obesity and ECPR were independently associated with UGIB. This study highlights the potential role of obesity and acute ischemia reperfusion injury in the pathophysiology of VA-ECMO-associated UGIB.

Abstract Background Hemorrhagic events remain a major concern in patients under extracorporeal membrane oxygenation (ECMO) support. We tested the association between anticoagulation levels and hemorrhagic events under ECMO using anti-Xa activity monitoring. Methods We performed a retrospective multicenter cohort study in three ECMO centers. All adult patients treated with veno-venous (VV)- or veno-arterial (VA)-ECMO in 6 intensive care units between September 2017 and August 2019 were included. Anti-Xa activities were collected until a hemorrhagic event in the bleeding group and for the duration of ECMO in the non-bleeding group. All dosages were averaged to obtain means of anti-Xa activity for each patient, and patients were compared according to the occurrence or not of bleeding. Results Among 367 patients assessed for eligibility, 121 were included. Thirty-five (29%) presented a hemorrhagic complication. In univariate analysis, anti-Xa activities were significantly higher in the bleeding group than in the non-bleeding group, both for the mean anti-Xa activity (0.38 [0.29–0.67] vs 0.33 [0.22–0.42] IU/mL; p = 0.01) and the maximal anti-Xa activity (0.83 [0.47–1.46] vs 0.66 [0.36–0.91] IU/mL; p = 0.05). In the Cox proportional hazard model, mean anti-Xa activity was associated with bleeding (p = 0.0001). By Kaplan–Meier analysis with the cutoff value at 0.46 IU/mL obtained by ROC curve analysis, the probability of survival under ECMO without bleeding was significantly lower when mean anti-Xa was > 0.46 IU/mL (p = 0.0006). Conclusion In critically ill patients under ECMO, mean anti-Xa activity was an independent risk factor for hemorrhagic complications. Anticoagulation targets could be revised downward in both VV- and VA-ECMO.

AbstractNon-hemorrhagic brain infarction (BI) is a recognized complication in adults treated with extracorporeal membrane oxygenation (ECMO) and associated with increased mortality. However, predictors of BI in these patients are poorly understood. The aim of this study was to identify predictors of BI in ECMO-treated adult patients. We conducted an observational cohort study of all adult patients treated with venovenous or venoarterial (VA) ECMO at our center between 2010 and 2018. The primary endpoint was a computed tomography (CT) verified BI. Logistic regression models were employed to identify BI predictors. In total, 275 patients were included, of whom 41 (15%) developed a BI. Pre-ECMO Simplified Acute Physiology Score III, pre-ECMO cardiac arrest, VA ECMO and conversion between ECMO modes were identified as predictors of BI. In the multivariable analysis, VA ECMO demonstrated independent risk association. VA ECMO also remained the independent BI predictor in a sub-group analysis excluding patients who did not undergo a head CT scan during ECMO treatment. The incidence of BI in adult ECMO patients may be higher than previously believed and is independently associated with VA ECMO mode. Larger prospective trials are warranted to validate these findings and ascertain their clinical significance.

Postcardiotomy Cardiogenic Shock

Background: The suitability of model for end-stage liver disease excluding international normalized ratio (MELD-XI) score to predict the incidence of acute kidney injury (AKI) and in-hospital mortality in adult patients with postcardiotomy cardiogenic shock (PCS) requiring venoarterial extracorporeal membrane oxygenation (VA ECMO) remains uncertain. This study was performed to explore whether the MELD-XI score has the association with the incidence of AKI and in-hospital mortality in these patients. Methods: Adult patients with PCS requiring VA ECMO from January 2012 to December 2017 were enrolled and first classified into AKI group ( n = 151) versus no-AKI group ( n = 132), then classified into survival group ( n = 143) versus no-survival group ( n = 140). Multivariate logistic regressions were performed to identify factors independently associated with AKI and mortality. Baseline data were defined as the first measurement available. Results: Of 283 patients, the incidence of AKI was 53.36%. The in-hospital mortality rates were 63.58% and 33.33% in patients with and without AKI (p < 0.0001). Baseline MELD-XI score, baseline serum total bilirubin (T-Bil), baseline blood urea nitrogen (BUN), baseline left ventricular ejection fraction (LVEF), sequential organ failure assessment (SOFA) score, and lactate level at ECMO initiation were shown to be associated with the AKI. Vasoactive-inotropic score (VIS) and SOFA score at ECMO initiation as well as renal failure requiring renal replacement therapy (RRT) were shown to be associated with in-hospital mortality. Conclusions: The baseline MELD-XI score, baseline BUN, baseline T-Bil, baseline LVEF, SOFA score and lactate at the initiation of ECMO were associated with AKI. AKI, SOFA score, and VIS at the initiation of ECMO were associated with in-hospital mortality, whereas MELD-XI score was not found to be associated with in-hospital mortality. A specific MELD-XI score as a threshold, as well as its sensitivity and specificity, needs to be confirmed in further studies.

Introduction: Extracorporeal membrane oxygenation (ECMO) is used to provide circulatory support and facilitate gas exchange via cardiopulmonary bypass. The relationship between ECMO and the incidence of severe thrombocytopenia (platelet count <50 x 10 9 /L) and subsequent clinical consequences are ill defined. We aimed to identify the risk factors for the development of thrombocytopenia and its clinical implications. Methods: This is a single-center retrospective cohort study of adults who received venoarterial (VA) ECMO. We examined consecutive platelet counts while on ECMO. Univariate logistic regression was used to determine if mean platelet count, platelet count range, or severe thrombocytopenia were predictors of overall survival, hemorrhage and thrombosis. A multivariate logistic regression model was used to identify factors that contribute to the development of the aforementioned patient outcomes. Results: In our cohort, 33 patients were included with a mean age of 55 years and duration of ECMO of 5.9 days. All patients received heparin, 33.3% received antiplatelet therapy and 45.5% developed severe thrombocytopenia. In univariate, analysis the development of severe thrombocytopenia increased the odds of major bleeding by 450% (OR 5.500, 95% CI 1.219 - 24.813, P -value 0.027), and the odds of surviving hospitalization decreased 84.1% (OR 0.159, 95% CI 0.033 - 0.773, P -value 0.023). Multivariate logistic regression controlling for additional clinical variables found no significant association between the development of severe thrombocytopenia and rates of thrombosis, hemorrhage, or overall survival. Platelet count decreased over time while on ECMO. Conclusions: Nearly half of the patients requiring VA-ECMO developed severe thrombocytopenia, which was associated with an increased risk of hemorrhage and in-hospital mortality. Additional studies are required to clarify the clinical implications of severe thrombocytopenia in ECMO patients.

Objective: To assess the association between PTGS1 and NOS3 variant alleles and the risk to develop upper gastrointestinal bleeding (UGIB) secondary to complicated peptic disease.Methods: A case–control study was conducted in a Brazilian complex hospital from July 2016 to March 2020. Case: Patients with UGIB diagnosis. Control: Patients admitted for surgery not related to gastrointestinal disorders. Variables: UGIB (outcome), genetic variants in PTGS1 and NOS3 genes (independent), and sex, age, schooling, ethnicity, previous history of gastrointestinal disorders, Helicobacter pylori serology, comorbidity, drug therapy, and lifestyle (confounding). The single-nucleotide polymorphisms (SNPs) of the PTSG1 gene (rs1330344, rs3842787, rs10306114, and rs5788) and NOS3 gene (rs2070744 and rs1799983) were determined using the real-time polymerase chain reaction. Helicobacter pylori serology was determined through the chemiluminescence technique. Logistic regression models were built and deviations of allelic frequencies from Hardy–Weinberg equilibrium were verified.Results: 200 cases and 706 controls were recruited. Carriers of the AG genotype of rs10306114 (OR: 2.55, CI 95%: 1.13–5.76) and CA + AA genotypes of rs5788 (OR: 2.53, CI 95%: 1.14–5.59) were associated with an increased risk for the UGIB development. In nonsteroidal anti-inflammatory drugs (NSAIDs) users, the six variants evaluated modified the magnitude of the risk of UGIB, whereas in low-dose aspirin (LDA) users, an increased risk of UGIB was observed for four of them (rs1330344, rs10306114, rs2070744, and rs1799983). Personal ulcer history (p-value: &lt; 0.001); Helicobacter pylori infection (p-value: &lt; 0.011); NSAIDs, LDA, and oral anticoagulant use (p-value: &lt; 0.001); and alcohol intake (p-value: &lt; 0.001) were also identified as independent risk factors for UGIB.Conclusion: This study presents two unprecedented analyses within the scope of the UGIB (rs10306114 and rs2070744), and our findings showing an increased risk of UGIB in the presence of the genetic variants rs10306114 and rs5788, regardless of the drug exposure. Besides, the presence of the evaluated variants might modify the magnitude of the risk of UGIB in LDA/NSAIDs users. Therefore, our data suggest the need for a personalized therapy and drug use monitoring in order to promote patient safety.

Introduction: Helicobacter pylori (H. pylori) is a well-recognized risk factor for upper gastrointestinal bleeding (UGIB). The exposure to tissue plasminogen activator (tPA), anti-platelets, and anticoagulants increases the risk of UGIB in acute ischemic stroke (AIS) patients, the risk stratification of H. pylori infection is not known. In this retrospective cross-sectional study, we aimed to evaluate the relationship between H. pylori and GIB in patients hospitalized with AIS. Methods: In the nationwide data, hospitalization for AIS was identified by primary diagnosis using International Classification of Diseases, clinical modification (ICD-9-CM) codes. Subgroup of patients with GIB and H. pylori were identified in AIS cohort. A stepwise multivariable logistic regression model was fitted to evaluate the outcome of upper GIB and role of H. Pylori in UGIB. Results: Overall 4,224,924 AIS hospitalizations were identified, out of which 18,629 (0.44%) had UGIB and 3122 (0.07%) had H. pylori. The prevalence of H. pylori-induced UGIB among UGIB in AIS was 3.05%. The prevalence of UGIB was markedly elevated among the H. pylori infection group (18.23% vs. 0.43%; p < 0.0001) compared to the non-H. pylori group. In multivariable regression analysis, H. pylori was associated with markedly elevated odds of UGIB (aOR:27.75; 95%CI: 21.07–36.55; p < 0.0001). Conclusion: H. pylori infection had increased risk-adjusted occurrence of UGIB amongst the AIS hospitalized patients. H. pylori testing may improve risk stratification for UGIB and lower the health care cost burden in stroke hospitalization.

Background: There is no heart transplantation centre on the French overseas territory of Reunion Island (distance of 10,000 km). The aim of this study was to describe the characteristics of cardiogenic shock adult patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) who were transferred from Reunion Island to mainland France for emergency heart transplantation. Methods: This retrospective observational study was conducted between 2005 and 2015. The characteristics and outcome of cardiogenic shock patients on VA-ECMO were compared with those of cardiogenic shock patients not on VA-ECMO. Results: Thirty-three cardiogenic shock adult patients were transferred from Reunion Island to Paris for emergency heart transplantation. Among them, 19 (57.6%) needed mechanical circulatory support in the form of VA-ECMO. Median age was 51 (33–57) years and 46% of the patients had ischaemic heart disease. Patients on VA-ECMO presented higher Sequential Organ Failure Assessment score ( p = 0.03). No death occurred during the medical transfer by long flight, while severe complications occurred in 10 patients (30.3%). Incidence of thromboembolic events, severe infectious complications and major haemorrhages was higher in the group of patients on VA-ECMO than in the group of patients not on VA-ECMO ( p <0.01). Seven patients from the VA-ECMO group (36.8%) and six patients from the non-VA-ECMO group (42.9%, p=0.7) underwent heart transplantation after a median delay of 10 (4–29) days on the emergency waiting list. After heart transplantation, one-year survival rates were 85.7% for patients on VA-ECMO and 83.3% for patients not on VA-ECMO ( p=0.91). Conclusions: This study suggests the feasibility of very long-distance medical evacuation of cardiogenic shock patients on VA-ECMO for emergency heart transplantation, with acceptable long-term results.

Background: There is a lack of consensus on the timing of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) liberation. VA-ECMO weaning usually consists of serial decrements until an idling flow is achieved, supported by echocardiographic and haemodynamic assessments. Even with minimal idling flow, right ventricular (RV) preload is reduced and, hence, right heart function is not fully tested under adequate loading conditions. Following the use of a novel technique called Pump Controlled Retrograde Trial Off (PCRTO) in neonate VA-ECMO weaning, we report the use of this technique in seven adult patients on VA-ECMO. Methods: We retrospectively reviewed all adult VA-ECMO patients treated at a tertiary teaching hospital in Hong Kong since 2010. Clinical data, including diagnosis, echocardiography findings, ECMO configuration, PCRTO settings, survival after veno-arterial ECMO (SAVE) score and outcomes, were collected. Mortality and death due to cardiac failure was compared between PCRTO and conventional weaning. Results: Seven patients underwent PCRTO, with a mean SAVE score of -4.4 ± 5.9. All seven patients were successfully decannulated without haemodynamic deterioration. In all cases, no clots or fibrin deposits were found in the circuit after the trial. There was no difference in mean SAVE scores among the seven patients in PCRTO and the 23 patients in the conventional group (-3.6, 95% CI -8.8 to 1.5). The number of deaths due to cardiac failure in the PCRTO group and the conventional group were 0 and 3, respectively (0% vs. 13%, p=0.99). Mortality after decannulation for PCRTO was 42.9% vs. conventional weaning 34.8% (p=0.99). Conclusion: Our study suggests that PCRTO is a simple, safe and reversible alternative weaning method. It may have a particular role in the assessment of patients who have marginal recovery and right heart failure. Prospective controlled studies are needed to establish the potential role of PCRTO in the liberation of patients from VA-ECMO support.

AbstractAcute kidney injury (AKI) has been reported as one of the most common complications in patients receiving extracorporeal membrane oxygenation (ECMO), yet the risk of AKI on different types of ECMO remains unclear. This meta-analysis aimed to compare risk of AKI among adult patients requiring different types of ECMO. Two authors independently performed a literature search using PubMed, Web of Science, and Embase, encompassing publications up until Arpril 20, 2020 (inclusive). The number of AKI patients, non-AKI patients, patients required RRT and patients not required RRT receiving different types of ECMO were derived and analyzed by STATA. The results indicated there was no significant difference in risk of AKI (OR, 1.54; 95% CI: 0.75-3.16; P= 0.235) and severe AKI required RRT (OR, 1.0; 95% CI: 0.66-1.5, P= 0.994) in patients receiving different types of ECMO. In Conclusion, no difference in risk of AKI and severe AKI required RRT between patients receiving VA ECMO and VV ECMO. More studies are required to support the findings.
