Septic shock and biliary sepsis: 90-day mortality and associated risk factors.

BACKGROUND: Biliary sepsis is common in patients with digestive cancer. Recommendations call for antibiotic de-escalation (ADE) as a strategy for antibiotic treatment of sepsis or septic shock. The aim of this study was to identify factors influencing 90-day mortality and to evaluate the impact of ADE. METHODS: This retrospective study was conducted between November 2008 and December 2019 in a referral cancer center. Adults with biliary sepsis or septic shock admitted to the ICU were included. Variables associated with 90-day mortality were identified using univariate and multivariate Cox proportional hazards models. RESULTS: 122 patients were included. The 90-day mortality was 30.3% (n = 37). After multivariate analysis, the factors independently associated 90-day mortality were metastatic stage (p = 0.004), biliary tract tumour compression (p = 0.001), multi drug resistant (MDR) bacteria carriage on intensive care unit (ICU)admission (p = 0.048), serum lactate on ICU admission (p < 0.001), the use of extra-renal replacement (p = 0.008), factor V < 50% (p = 0.009) and performance status (ECOG-PS) > 2 (p < 0.001). ADE of the pivotal antibiotic (p = 0.041) and recent cancer surgery (p < 0.001) appeared to be associated with survival. CONCLUSION: The 90-day mortality of biliary sepsis seems to be favourable. The 90-day mortality is associated with organ dysfunctions, but also with ECOG-PS, cancer stage, MDR bacteria colonisation. ADE seems to be safe.

Factors Associated with 1-Year Mortality in Elderly Patients (Age ≥ 80 Years) with Cancer Undergoing Major Abdominal Surgery: A Retrospective Cohort Study.

BACKGROUND: The number of elderly patients undergoing major abdominal surgery is increasing, but the factors affecting their postoperative outcomes remain unclear. This study aimed to identify the factors associated with 1-year mortality among elderly patients (age ≥ 80 years) with cancer undergoing major abdominal surgery. METHODS: This retrospective cohort study was conducted from March 2009 to December 2020. The study enrolled 378 patients 80 years old or older who underwent major abdominal surgery. The main outcome was 1-year mortality, and the factors associated with mortality were analyzed. RESULTS: Of the 378 patients, 92 died at 1 year (24.3%), whereas the 30-day mortality rate was 4% (n = 15). In the multivariate analysis, the factors independently associated with 1-year mortality were preoperative Eastern Cooperative Oncology Group (ECOG) performance status (PS) score higher than 1 (odds ratio [OR], 3.189; 95% confidence interval [CI], 1.595-6.377; p = 0.001), preoperative weight loss greater than 3 kg (OR, 2.145; 95% CI, 1.044-4.404; p = 0.038), use of an intraoperative vasopressor (OR, 3.090; 95% CI, 1.188-8.042; p = 0.021), and postoperative red blood cell units (OR, 1.212; 95% CI, 1.045-1.405; p = 0.011). Survival was associated with perioperative management according to an enhanced recovery after surgery (ERAS) protocol (OR, 0.370; 95% CI, 0.160-0.854; p = 0.006) and supramesocolic surgery (OR, 0.371; 95% CI, 0.158-0.871; p = 0.023). CONCLUSION: The study identified several factors associated with an encouraging 1-year mortality rate in this setting. These results highlight the need for identification of suitable targets to optimize pre-, intra-, and postoperative management in order to improve outcomes for this vulnerable population.

Hepatic haemophagocytosis in haematology patients with hepatic dysfunction: prognostic impact and contribution of liver biopsy combined with the haemophagocytic syndrome diagnostic score (HScore).

Hepatic dysfunction (HD) is common in patients with haematological malignancies. Hepatic haemophagocytosis (HH) was detected in >50% of liver biopsies taken when HD remained unresolved after standard examination. We aimed to explore the contribution of liver biopsy in patients with both haematological malignancies and HD, describe the population of patients with HH, assess the prognostic impact of HH, and investigate haemophagocytic syndrome diagnostic score (HScore) utility in patients with HH. Between 2016 and 2019, 116 consecutive liver biopsies (76 transjugular, 40 percutaneous) were taken in 110 patients with haematological malignancy and HD (hyperbilirubinaemia, elevated transaminases, and/or cholestasis) and without a clear diagnosis. Liver biopsies were safe and diagnostically efficient. Predominant diagnoses included: HH (56%), graft-versus-host disease (55%), associated infections (24%), sinusoidal obstruction syndrome (15%), and tumoral infiltration (8%). Of patients, 35% were critically ill and 74% were allogeneic haematopoietic stem cell transplantation recipients, while 1-year overall survival (OS) was 35% with HH versus 58% without HH (p = 0.026). The 1-year OS was 24% with a HScore of ≥169 versus 50% with a HScore of <169 (p = 0.019). Liver biopsies are feasible in and contribute significantly to haematology patients with HD. HH occurred frequently and was associated with a poor prognosis. Combined with liver biopsy, the HScore may be helpful in refining haemophagocytic syndrome diagnosis.

Effect of Noninvasive Ventilation on Tracheal Reintubation Among Patients With Hypoxemic Respiratory Failure Following Abdominal Surgery: A Randomized Clinical Trial.

IMPORTANCE: It has not been established whether noninvasive ventilation (NIV) reduces the need for invasive mechanical ventilation in patients who develop hypoxemic acute respiratory failure after abdominal surgery. OBJECTIVE: To evaluate whether noninvasive ventilation improves outcomes among patients developing hypoxemic acute respiratory failure after abdominal surgery. DESIGN, SETTING, AND PARTICIPANTS: Multicenter, randomized, parallel-group clinical trial conducted between May 2013 and September 2014 in 20 French intensive care units among 293 patients who had undergone abdominal surgery and developed hypoxemic respiratory failure (partial oxygen pressure <60 mm Hg or oxygen saturation [SpO2] ≤90% when breathing room air or <80 mm Hg when breathing 15 L/min of oxygen, plus either [1] a respiratory rate above 30/min or [2] clinical signs suggestive of intense respiratory muscle work and/or labored breathing) if it occurred within 7 days after surgical procedure. INTERVENTIONS: Patients were randomly assigned to receive standard oxygen therapy (up to 15 L/min to maintain SpO2 of 94% or higher) (n = 145) or NIV delivered via facial mask (inspiratory pressure support level, 5-15 cm H2O; positive end-expiratory pressure, 5-10 cm H2O; fraction of inspired oxygen titrated to maintain SpO2 ≥94%) (n = 148). MAIN OUTCOMES AND MEASURES: The primary outcome was tracheal reintubation for any cause within 7 days of randomization. Secondary outcomes were gas exchange, invasive ventilation-free days at day 30, health care-associated infections, and 90-day mortality. RESULTS: Among the 293 patients (mean age, 63.4 [SD, 13.8] years; n=224 men) included in the intention-to-treat analysis, reintubation occurred in 49 of 148 (33.1%) in the NIV group and in 66 of 145 (45.5%) in the standard oxygen therapy group within+ 7 days after randomization (absolute difference, -12.4%; 95% CI, -23.5% to -1.3%; P = .03). Noninvasive ventilation was associated with significantly more invasive ventilation-free days compared with standard oxygen therapy (25.4 vs 23.2 days; absolute difference, -2.2 days; 95% CI, -0.1 to 4.6 days; P = .04), while fewer patients developed health care-associated infections (43/137 [31.4%] vs 63/128 [49.2%]; absolute difference, -17.8%; 95% CI, -30.2% to -5.4%; P = .003). At 90 days, 22 of 148 patients (14.9%) in the NIV group and 31 of 144 (21.5%) in the standard oxygen therapy group had died (absolute difference, -6.5%; 95% CI, -16.0% to 3.0%; P = .15). There were no significant differences in gas exchange. CONCLUSIONS AND RELEVANCE: Among patients with hypoxemic respiratory failure following abdominal surgery, use of NIV compared with standard oxygen therapy reduced the risk of tracheal reintubation within 7 days. These findings support use of NIV in this setting. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01971892.

Empirical antifungal therapy for health care-associated intra-abdominal infection: a retrospective, multicentre and comparative study.

BACKGROUND: Current guidelines recommend using antifungals for selected patients with health care-associated intra-abdominal infection (HC-IAI), but this recommendation is based on a weak evidence. This study aimed to assess the association between early empirical use of antifungals and outcomes in intensive care unit (ICU) adult patients requiring re-intervention after abdominal surgery. METHODS: A retrospective, multicentre cohort study with overlap propensity score weighting was conducted in three ICUs located in three medical institutions in France. Patients treated with early empirical antifungals for HC-IAI after abdominal surgery were compared with controls who did not receive such antifungals. The primary endpoint was the death rate at 90 days, and the secondary endpoints were the death rate at 1 year and composite criteria evaluated at 30 days following the HC-IAI diagnosis, including the need for re-intervention, inappropriate antimicrobial therapy and death, whichever occurred first. RESULTS: At 90 days, the death rate was significantly decreased in the patients treated with empirical antifungals compared with the control group (11.4% and 20.7%, respectively, p = 0.02). No differences were reported for the secondary outcomes. CONCLUSION: The use of early empirical antifungal therapy was associated with a decreased death rate at 90 days, with no effect on the death rate at 1 year, the death rate at 30 days, the rate of re-intervention, the need for drainage, and empirical antibiotic and antifungal therapy failure at 30 days.

Acute pulmonary embolism in cancer patients admitted to intensive care unit: Impact of anticoagulant treatment on 90-day mortality and risk factors, results of a multicentre retrospective study.

BACKGROUND: Acute pulmonary embolism (PE) is a life-threatening situation in cancer patients. In this situation, anticoagulant therapy is complex to administer due to the risk of bleeding. Only few studies have been conducted when these patients are admitted to the intensive care unit (ICU). The aim of this study was to assess the association between anticoagulation strategies as well as other factors with 90-day mortality in patients with cancer and PE admitted to ICU. Major bleeding was also evaluated according to the type of anticoagulation. METHODS: Retrospective study carried out in 4 ICUs in France over a 12-year period (2009-2021). All patients with cancer and PE were included. An overlap propensity score weighting analysis was performed in the subgroup of patients treated with either unfractionated heparins (UFH) alone or low-molecular-weight heparins (LMWH) alone on 90-day mortality and major bleeding. RESULTS: A total of 218 consecutive cancer patients admitted to ICU and presenting PE were included. The 90-day mortality rate was 42 % for the global cohort. After propensity score analysis in the subgroup of patients treated with either "UFH alone" (n = 80) or "LMWH alone" (n = 71), the 90-day mortality was similar in patients treated with UFH alone (42.6 %) vs LMWH alone (39.9 %): OR = 1.124, CI 95 % [0.571-2.214], p = 0.750. There was a significant increased toward major bleeding rates in the "UFH alone" group (25.5 %) as compared to "LMWH alone" group (11.5 %), p = 0.04. CONCLUSION: In 218 patients admitted to ICU and presenting PE, the 90-day mortality rate was 42 %. Treatment with UFH alone was associated with a mortality comparable to treatment with LMWH alone but it appeared to be more prone to major bleeding.

Prophylactic versus restrictive platelet transfusion strategy in patients with haematological malignancies in the ICU setting, a propensity-score analysis.

PURPOSE: Prophylactic platelet transfusions (PT) aim to reduce bleeding. We assessed whether restrictive PT compared to prophylactic strategy could apply in ICU. MATERIAL AND METHODS: We conducted a retrospective monocentric study including patients >18 yo with haematological malignancy admitted to the ICU with thrombocytopenia <20 G/L between 2018 and 2021. Patients were classified in 2 groups according transfusion strategy applied during the first 3 days: prophylactic or restrictive transfusion. RESULTS: 180 patients were included, 87 and 93 in the restrictive and prophylactic groups respectively. After propensity-score analysis, 2 groups of 54 matched patients were analyzed. Restrictive strategy led to a significant reduction in PT with incidence rate for 100-ICU-patients-days of 34.9 and 49.9, incidence rate ratio = 0.699 [0.5-0.9], p = 0.006, representing a 31% decrease. Decreased PT persisted until day 28 with platelet concentrates transfusions-free days at day 28 of 21 [13-25] and 16.5 [10.2-21] in the 2 groups (p = 0.04). Restrictive strategy did not result in higher grade ≥ 2 bleeding. Transfusion efficiency was low with similar number of days with platelet <10 or < 20 G/L regardless of strategy. Platelet transfusion strategy was not associated with 28-day mortality. Platelet nadir <5G/L was associated with day-28 mortality with HR = 1.882 [1.011-3.055], p = 0.046. CONCLUSION: A restrictive PT strategy appears feasible in the ICU.

Critically ill metastatic cancer patients returning home after unplanned ICU stay: an observational, multicentre retrospective study.

BACKGROUND: Data about critically ill metastatic cancer patients functional outcome after unplanned admission to the ICU are scarce. The aim of this study was to assess factors associated with 90-day return home and 1-year survival in this population. STUDY DESIGN AND METHODS: A multicenter retrospective study included all consecutive metastatic cancer patients admitted to the ICU for unplanned reason between 2017 and 2020. RESULTS: Among 253 included metastatic cancer patients, mainly with lung cancer, 94 patients (37.2%) could return home on day 90. One-year survival rate was 28.5%. Performance status 0 or 1 (OR, 2.18; 95% CI 1.21-3.93; P = 0.010), no malnutrition (OR, 2.90; 95% CI 1.61-5.24; P < 0.001), female gender (OR, 2.39; 95% CI 1.33-4.29; P = 0.004), recent chemotherapy (OR, 2.62; 95% CI 1.40-4.90; P = 0.003), SOFA score ≤ 5 on admission (OR, 2.62; 95% CI 1.41-4.90; P = 0.002) were significantly predictive for 90-day return home. Malnutrition (HR, 1.66; 95% CI 1.18-2.22; P = 0.003), acute respiratory failure (ARF) as reason for admission (HR, 1.40; 95% CI 1.10-1.95; P = 0.043), SAPS II on admission (HR, 1.03; 95% CI 1.02-1.05; P < 0.001) and decisions to forgo life-sustaining therapies (DFLST) (HR, 2.80; 95% CI 2.04-3.84; P < 0.001) were independently associated with 1-year mortality. CONCLUSIONS: More than one out of three metastatic cancer patients could return home within 3 months after an unplanned admission to the ICU. Previous performance and nutritional status, ongoing specific treatment and low severity of the acute illness were found to be predictive for return home. Such encouraging findings should help change the dismal perception of critically ill metastatic cancer patients.

Prognosis of acute respiratory distress syndrome in neutropenic cancer patients.

To date, no study has been specifically designed to identify determinants of death in neutropenic cancer patients presenting with acute respiratory distress syndrome (ARDS). The aim of this study was to identify early predictive factors of 28-day mortality in these patients. Factors associated with 28-day mortality during intensive care unit (ICU) stay were also described. 70 consecutive cancer patients with ARDS and neutropenia were prospectively analysed over a 6-yr period. Mortality at 28 days was 63%. Factors independently associated with good prognosis were: lobar ARDS (OR 0.10, 95% CI 0.02-0.48), use of initial antibiotic treatment active on difficult to treat bacteria (ticarcillin-resistant Pseudomonas aeruginosa, Stenotrophomonas maltophilia or extended-spectrum ß-lactamase-producing strains) (OR 0.08, 95% CI 0.02-0.33) and first-line chemotherapy (OR 0.08, 95% CI 0.02-0.37). During the ICU stay, mortality was associated with the markers of organ dysfunctions, the absence of neutropenia recovery and the use of vasopressors. During the first 3 weeks, the conditional probability of discharge alive from ICU did not decrease. At ICU admission, first-line chemotherapy, lobar ARDS and antibiotic treatment active on difficult-to-treat bacteria were associated with survival. During ICU stay, mortality was associated with organ dysfunctions and use of vasopressors. Most survivors have an ICU stay of >3 weeks.

High-flow nasal cannula failure in critically ill cancer patients with acute respiratory failure: Moving from avoiding intubation to avoiding delayed intubation.

BACKGROUND: High-flow nasal cannula (HFNC) is increasingly used in critically ill cancer patients with acute respiratory failure (ARF) to avoid mechanical ventilation (MV). The objective was to assess prognostic factors associated with mortality in ICU cancer patients requiring MV after HFNC failure, and to identify predictive factors of intubation. METHODS: We conducted a retrospective study from 2012-2016 in a cancer referral center. All consecutive onco-hematology adult patients admitted to the ICU treated with HFNC were included. HFNC failure was defined by intubation requirement. RESULTS: 202 patients were included, 104 successfully treated with HFNC and 98 requiring intubation. ICU and hospital mortality rates were 26.2% (n = 53) and 42.1% (n = 85) respectively, and 53.1% (n = 52) and 68.4% (n = 67) in patients requiring MV. Multivariate analysis identified 4 prognostic factors of hospital mortality after HFNC failure: complete/partial remission (OR = 0.2, 95%CI = 0.04-0.98, p<0.001) compared to patients with refractory/relapse disease (OR = 3.73, 95%CI = 1.08-12.86), intubation after day 3 (OR = 7.78, 95%CI = 1.44-41.96), number of pulmonary quadrants involved on chest X-ray (OR = 1.93, 95%CI = 1.14-3.26, p = 0.01) and SAPSII at ICU admission (OR = 1.06, 95%CI = 1-1.12, p = 0.019). Predictive factors of intubation were the absence of sepsis (sHR = 0.32, 95%CI = 0.12-0.74, p = 0.0087), Sp02<95% 15 minutes after HFNC initiation (sHR = 2.05, 95%CI = 1.32-3.18, p = 0.0014), number of quadrants on X-ray (sHR = 1.73, 95%CI = 1.46-2.06, p<0.001), Fi02>60% at HFNC initiation (sHR = 3.12, 95%CI = 2.06-4.74, p<0.001) and SAPSII at ICU admission (sHR = 1.03, 95%CI = 1.02-1.05, p<0.01). CONCLUSION: Duration of HFNC may be predictive of an excess mortality in ARF cancer patients. Early warning scores to predict HFNC failure are needed to identify patients who would benefit from early intubation.

Feasibility of Cyclosporine Prophylaxis Withdrawal in Critically Ill Allogenic Hematopoietic Stem Cell Transplant Patients Admitted to the Intensive Care Unit With No GVHD.

Twenty percent of allogenic hematopoietic stem cell transplantation (allo-HSCT) patients require intensive care unit (ICU) admission. Feasibility and long-term consequences of cyclosporine graft-versus-host disease (GVHD) prophylaxis withdrawal in the ICU are unknown. To assess the impact of cyclosporine prophylaxis withdrawal in critically ill allo-HSCT patients admitted to the ICU on GVHD incidence and to evaluate 6-month overall survival according to cyclosporine withdrawal and GVHD occurrence. From 2010 to 2020, 101 critically ill allo-HSCT patients admitted to the ICU in our institution were included. All received cyclosporine as GVHD prophylaxis. None of them had GVHD at ICU admission. Patients were admitted in the ICU after a median time of 11 days (5.5-18) after allo-HSCT. ICU, hospital mortality, and 6-month mortality were 43.6%, 56.4%, and 59.4%, respectively. Cyclosporine was withdrawn for 52 and continued for 49 patients in the ICU. A total of 38.6% (n = 39) developed secondarily acute GVHD (aGVHD) after a median of 28 days (15-40) after cyclosporine was discontinued. In 74.4% (n = 29) of cases, patients in the hematology ward developed aGVHD after ICU discharge. Cyclosporine dosages were similar in both groups. Factors independently associated with aGVHD occurrence in multivariate analysis were cyclosporine withdrawal in the ICU (subdistribution hazard ratios [sHR] = 2.04, 95% confidence interval [CI] = 1.02-4.1, P = .044), renal replacement therapy (RRT) (sHR = 0.43, 95% CI = 0.19-0.9, P = .03) and fungal prophylaxis (sHR = 2.62, 95% CI = 1.35-5.07, P = .004). Cyclosporine withdrawal in the ICU was associated with poorer 6-month overall survival (OS) (HR = 1.96, 95% CI = 1.16-3.33, P = .012), but after adjusting on severity (simplified acute physiology score, vasopressors, mechanical ventilation and RRT requirement), 6-month OS did not differ (HR = 1.35, 95% CI = 0.76-2.42, P = .30). GVHD occurrence after ICU stay was significantly associated with better 6-month OS in unadjusted (HR = 0.53, 95% CI = 0.31-0.90, P = .02) and severity-adjusted analysis (HR = 0.54, 95% CI = 0.31-0.93, P = .028). Cyclosporine prophylaxis withdrawal in critically ill allo-HSCT patients in the ICU appears to be feasible and did not impair long-term outcome.

LATE POSTPANCREATICODUODENECTOMY HEMORRHAGE: INCIDENCE, RISK FACTORS, MANAGEMENT AND OUTCOME.

ABSTRACT: Background:Postpancreaticoduodenectomy (PD) hemorrhage (PPH) is a life-threatening complication after PD. The main objective of this study was to evaluate incidence and factors associated with late PPH as well as the management strategy and outcomes. Methods: Between May 2017 and March 2020, clinical data from 192 patients undergoing PD were collected prospectively in the CHIRPAN Database (NCT02871336) and retrospectively analyzed. In our institution, all patients scheduled for a PD are routinely admitted for monitoring and management in intensive/intermediate care unit (ICU/IMC). Results: The incidence of late PPH was 17% (32 of 192), whereas the 90-day mortality rate of late PPH was 19% (6 of 32). Late PPH was associated with 90-day mortality (P = 0.001). Using multivariate analysis, independent risk factors for late PPH were postoperative sepsis (P = 0.036), and on day 3, creatinine (P = 0.025), drain fluid amylase concentration (P = 0.023), lipase concentration (P < 0.001), and C-reactive protein (CRP) concentration (P < 0.001). We developed two predictive scores for PPH occurrence, the PANCRHEMO scores. Score 1 was associated with 68.8% sensitivity, 85.6% specificity, 48.8% predictive positive value, 93.2% negative predictive value, and an area under the receiver operating characteristic curves of 0.841. Score 2 was associated with 81.2% sensitivity, 76.9% specificity, 41.3% predictive positive value, 95.3% negative predictive value, and an area under the receiver operating characteristic curve of 0.859. Conclusions: Routine ICU/IMC monitoring might contribute to a better management of these complications. Some predicting factors such as postoperative sepsis and biological markers on day 3 should help physicians to determine patients requiring a prolonged ICU/IMC monitoring.

Herpesviridae in critically ill hematology patients: HHV-6 is associated with worse clinical outcome.

PURPOSE: Although viral infections are frequent among patients with hematological malignancies (HM), data about herpesviridae in critically ill hematology patients are scarce. We aimed at determining the impact of herpesviridae reactivation/infection in this population. MATERIAL AND METHODS: We performed a single center retrospective study including all consecutive adult hematology patients admitted to our comprehensive cancer center ICU on a 6-year period. Clinical characteristics, microbiological findings, especially virus detection and outcome were recorded. RESULTS: Among the 364 included patients, HHV-6 was the predominant retrieved herpesviridae (66 patients, 17.9%), followed by HSV1/2 (41 patients, 11.3%), CMV (38 patients, 10.4%), EBV (24 patients, 6.6%) and VZV (3 patients). By multivariable analysis, HHV-6 reactivation was independently associated with hospital mortality (OR, 2.35; 95% CI, 1.03-5.34; P = 0.042), whereas antiviral prophylaxis during ICU stay had a protective effect (OR, 0.41; 95% CI, 0.18-0.95; P = 0.037). HHV-6 pneumonitis was independently associated with 1-year mortality (OR, 6.87; 95% CI, 1.09-43.3; P = 0.04). CONCLUSIONS: Among critically ill hematology patients, HHV-6 reactivation and pneumonitis are independent risk factors for hospital and 1-year mortality, respectively. Impact of prevention and treatment using agents active against HHV-6 should be assessed to define a consensual diagnostic and therapeutic strategy.

Prognostic impact of early adjunctive corticosteroid therapy in non-HIV oncology or haematology patients with Pneumocystis jirovecii pneumonia: A propensity score analysis.

PURPOSE: While early adjunctive corticosteroid therapy (EACST) has been proven effective in HIV patients with Pneumocystis Jirovecii Pneumonia (PJP), data remains controversial concerning non-HIV oncology or haematology patients. METHODS: This retrospective study included cancer patients without HIV and with diagnosis of PJP admitted in a cancer referral centre, from January-1-2010 to March-31-2017. We compared 30-day and 1-year mortality rate, change in the respiratory item of the Sequential Organ Failure Assessment score(SOFA-resp worsening), use of tracheal intubation between day-1 and day-5 of anti-pneumocystis therapy and occurrence of coinfections between patients with EACST and those with no or late corticosteroid therapy, using an inverse probability weighting propensity score-based (IPW) analysis. RESULTS: 133 non-HIV oncology or haematology PJP patients were included (EACST n = 58, others n = 75). The main underlying conditions were haematological malignancies (n = 107, 80,5%), solid tumour (n = 27, 20,3%) and allogeneic stem cell transplantation (n = 17, 12,8%). Overall 30-day and 1-year mortality rate was 24,1% and 56,4%, respectively. IPW analysis found no difference on 30-day (HR = 1.45, 95% CI [0.7-3.04], p = 0.321) and 1-year (HR = 1.25, CI 95% [0.75-2.09], p = 0.39) mortality rate between groups. CONCLUSION: No difference in SOFA-resp worsening, tracheal intubation and coinfections was found between groups. Combination of EACST with anti-pneumocystis therapy in non-HIV onco-haematology PJP-patients was not associated with clinical improvement.

Non-invasive ventilation indication for critically ill cancer patients admitted to the intensive care unit for acute respiratory failure (ARF) with associated cardiac dysfunction: Results from an observational study.

BACKGROUND: Acute respiratory failure (ARF) is a life-threatening complication in onco-hematology patients. Optimal ventilation strategy in immunocompromised patients has been highly controversial over the last decade. Data are lacking on patients presenting with ARF associating isolated cardiac dysfunction or in combination with another etiology. The aim of this study was to assess prognostic impact of initial ventilation strategy in onco-hematology patients presenting ARF with associated cardiac dysfunction. METHODS: We conducted an observational retrospective study in Institut Paoli-Calmettes, a cancer-referral center, assessing all critically ill cancer patients admitted to the ICU for a ARF with cardiac dysfunction. RESULTS: Between 2010-2017, 127 patients were admitted. ICU and hospital mortality were 29% and 57%. Initial ventilation strategy was invasive mechanical ventilation (MV) in 21%. Others ventilation strategies were noninvasive ventilation (NIV) in 50%, associated with oxygen in 21% and high flow nasal oxygen (HFNO) in 29%, HFNO alone in 6% and standard oxygen in 23%. During ICU stay, 48% of patients required intubation. Multivariate analysis identified 3 independent factors associated with ICU mortality: SAPSII at admission (OR = 1.07/point, 95%CI = 1.03-1.11, p<0.001), invasive fungal infection (OR = 7.65, 95%CI = 1.7-34.6, p = 0.008) and initial ventilation strategy (p = 0.015). Compared to NIV, HFNO alone and standard oxygen alone were associated with an increased ICU mortality, with respective OR of 19.56 (p = 0.01) and 10.72 (p = 0.01). We realized a propensity score analysis including 40 matched patients, 20 in the NIV arm and 20 receiving others ventilation strategies, excluding initial MV patients. ICU mortality was lower in patients treated with NIV (10%), versus 50% in the other arm (p = 0.037). CONCLUSION: In onco-hematology patients admitted for ARF with associated cardiac dysfunction, severity at ICU admission, invasive fungal infections and initial ventilation strategy were independently associated with ICU mortality.

Intraoperative Hemorrhagic Shock in Cancer Surgical Patients: Short and Long-Term Mortality and Associated Factors.

BACKGROUND: Management of hemorrhagic shock is well codified by international guidelines. These guidelines are predominantly based on trauma patients. We aimed to evaluate factors associated with 30-day mortality and long-term survival after intraoperative hemorrhagic shock during major oncological surgery. METHODS: This retrospective study was conducted in a cancer referral center from January 2013 to February 2018. All adult cancer patients admitted in the operative room for scheduled or emergency oncological surgery associated with an intraoperative hemorrhagic shock were included. RESULTS: Eighty-four patients were included in this study. The 30-day mortality rate was 26% (n = 22), the mean follow-up from the time of ICU admission was 20 months (95% CI, 15-25 months), 39 (46%) patients died during this period. Using logistic regression for multivariate analysis, factors independently associated with 30-day mortality were SAPS II score (odds ratio (OR) =1.056, 95% confident interval (CI) =1.010-1.1041), delta SOFA (SOFA score at day 3 - SOFA score at day 1) (OR= 1.780, 95% CI 1.184-2.677) and ISTH-DIC score (OR = 2.705, 95% CI 1.108-6.606). Using Cox multivariate analysis, factors associated with long-term mortality were delta SOFA (hazard ratio (HR) =1.558, 95% CI 1.298-1.870), ISTH-DIC score (HR = 1.381, 95% CI 1.049-1.817), hepatic dysfunction (HR = 7.653, 95% CI 2.031-28.842), and Charlson comorbidity index (HR = 1.330, 95% CI 1.041-1.699). CONCLUSION: The worsening of organ dysfunctions during the first 3 days of ICU admission as well as intraoperative coagulation disturbances (increased ISTH-DIC score) are independently associated with short and long-term mortality. Comorbidities (Charlson comorbidity index) and postoperative hepatic dysfunction were independently associated with long-term mortality. Early perioperative bundle strategies should be evaluated in order to improve patient's survival in this specific situation.

Impact of a computer-assisted decision support system (CDSS) on nutrition management in critically ill hematology patients: the NUTCHOCO study (nutritional care in hematology oncologic patients and critical outcome).

BACKGROUND: Mortality of critically ill hematology (HM) patients has improved over time. Thus, those patients require an extensive diagnostic workup and the optimal use of available treatments. There are no data regarding nutrition strategy for critically ill HM patients, while nutritional support is crucial for both HM and critically ill patients. We hypothesized that the implementation of a computer-assisted decision support system (CDSS), designed to supervise a nutritional intervention by a multidisciplinary team, would be able to increase guidelines adherence and outcomes. RESULTS: In this before/after study, 275 critically ill hematology patients admitted to the ICU over 5-year period were included. Energy and protein intakes were delivered using standard protocol in the 147 patients (53%) of the 'before group' and using a CDSS in order to reach every day predefined caloric and protein targets accordingly to the catabolic or anabolic status in the 128 patients (47%) of the 'after group.' Using a Poisson regression, we showed that the use of CDSS allowed to reach a relative increase in the rate of days in compliance with caloric (1.57; 95% confidence interval (CI), [1.17-2.10], p = 0.0025) and protein targets (3.86 [2.21-6.73], p < 0.0001) in the 'after group' by more than 50% as compared with the 'before group.' Interestingly, compliance rates were low and only reached 30% after intervention. Hospital mortality, ICU-acquired infection, and hospital, and ICU length of stay were similar in the two groups of patients. Importantly, exploratory analysis showed that hospital mortality was lower in the 'after group' for neutropenic and severely ill patients. CONCLUSION: For critically ill hematology patients, the use of a nutritional CDSS allowed to increase the days in compliance with caloric and protein targets as compared with no CDSS use. In this context, overall hospital mortality was not affected.

Successful Imatinib Treatment of an Abdominal Compartment Syndrome due to Huge Gastrointestinal Stromal Tumour.

Gastrointestinal stromal tumours (GISTs) are the most common digestive mesenchymal tumours, whose prognosis has been revolutionised by targeted therapies such as oral imatinib. Abdomen compartment syndrome (ACS) is associated with mortality superior to 50% in adults. ACS has never been reported to date in patients with GIST. Specific anticancer treatment in critically ill patients in intensive care unit (ICU) remains a matter of debate given the high mortality rate. Here, we report the case of a 58-year-old woman with ACS related to a 40-cm huge GIST and multi-organ failure requiring mechanical ventilation, vasopressive support and haemodialysis. She was treated in emergency with imatinib via the naso-gastric tube (day 1), then at day 3 by decompressive laparotomy and "open abdomen" without any tumour removal. Imaging after 11 days imatinib showed objective tumour response. Because of improvement of multi-organ dysfunctions, the laparotomy was closed at day 14, and the resuscitation procedures were progressively stopped. After discharge from hospital, she survived nearly two years. This is the first case of successful treatment of cancer-associated ACS by targeted therapy and decompressive laparotomy. Imatinib in critically ill patients with GIST may be successful even in presence of multi-organ failure.
