RESUMO
BACKGROUND: Cytomegalovirus (CMV) infection is associated with poor outcome in ICU patients. However, data on immunocompromised patients are scarce. This study aims to describe characteristics and outcomes of critically ill hematological patients and CMV infection. CMV disease characteristics and relationship between CMV viral load, CMV disease, coinfections by other pathogens and outcomes are described. METHODS: Retrospective single center study (Jan 2010-Dec 2017). Adult patients, admitted to the ICU, having underlying hematological malignancy and CMV infection were included. Results are reported as median (interquartile) or n (%). Factors associated with hospital mortality or CMV disease were analysed using logistic regression. RESULTS: 178 patients were included (median age 55y [42-64], 69.1% male). Hospital mortality was 53% (n = 95). Median viral load was 2.7 Log [2.3-3.5]. CMV disease occurred in 44 (24.7%) patients. Coinfections concerned 159 patients (89.3%). After adjustment for confounders, need for vasopressors (OR 2.53; 95%CI 1.11-5.97) and viral load (OR 1.88 per Log; 95%CI 1.29-2.85) were associated with hospital mortality. However, neither CMV disease nor treatment were associated with outcomes. Allogeneic stem cell transplantation (OR 2.55; 95%CI 1.05-6.16), mechanical ventilation (OR 4.11; OR 1.77-10.54) and viral load (OR 1.77 per Log; 95%CI 1.23-2.61) were independently associated with CMV disease. Coinfections were not associated with CMV disease or hospital mortality. CONCLUSION: In critically-ill hematological patients, CMV viral load is independently associated with hospital mortality. Conversely, neither CMV disease nor treatment was associated with outcome suggesting viral load to be a surrogate for immune status rather than a cause of poor outcome.

OBJECTIVES: Physiotherapy leads to improvements in critically ill patients who receive mechanical ventilation. However, cancer patients have not been included in previous studies on this subject. This study explored the feasibility and safety of physiotherapy in the intensive care unit for patients with malignancy. DESIGN: Observational prospective single-centre study, comparing cancer and control patients. PATIENTS: All consecutive patients admitted to the intensive care unit who needed invasive mechanical ventilation for more than 2 days with no contraindication to physiotherapy were included in the study. METHODS: The main outcome was the proportion of physiotherapy sessions at the prescribed level in each group. RESULTS: A total of 60 patients were included within 1 year. A total of 576 days were screened for physiotherapy sessions and 367 physiotherapy-days were analysed (137 days for control patients and 230 days for cancer patients). The ratio of physiotherapy sessions performed/prescribed did not differ between groups: 0.78 (0.47-1) in the control group vs 0.69 (0.6-1) in the cancer group (odds ratio 1.18 (IC95% 0.74-1.89); p = 0.23). A sensitivity analysis including patient effect as random variable confirmed those results (odds ratio 1.16 (0.56-2.38), p = 0.69). Adverse events occurred with the same frequency in cancer patients and non-cancer patients. CONCLUSION: Physiotherapy in cancer patients who require intubation is feasible and safe. However, only two-thirds of prescribed physiotherapy sessions were performed. Studies are warranted to explore the barriers to physiotherapy in the intensive care unit setting.

OBJECTIVE: We assessed herpesvirus reactivation in severe SARS-CoV-2 infection. METHODS: Retrospective study including consecutive patients admitted to an onco-hematology intensive care unit (ICU) for severe COVID-19. Replication of EBV, CMV, and HSV was evaluated. Competing risk analyses were used to assess the cumulative risk of viral reactivation, and time-dependent Cox and Fine and Gray models to assess risk factors for viral reactivation. RESULTS: Among 100 patients, 38 were immunocompromised. Sixty-three patients presented viral reactivation (12% for HSV, 58% EBV and 19% CMV). Symptomatic patients received treatment. Overall cumulative incidence of viral reactivation was 56.1% [55.9-56.4] at 10 days. After adjustment, a preexisting hematological malignancy (sHR [95%CI]=0.31 [0.11-0.85]) and solid organ transplantation (sHR [95% CI]=2.09 [1.13-3.87]) remained independently associated with viral reactivation. Viral reactivation (P=0.34) was not associated with mortality. CONCLUSIONS: Incidence of herpesvirus reactivation in patients admitted to the ICU for severe COVID-19 was high, but rarely required antiviral treatment.

SETTING: Tuberculosis (TB) is a potential trigger of haemophagocytic syndrome (HS) but little is known about the features of TB-associated HS.OBJECTIVE: To assess the risk factors associated with HS in patients with TB.DESIGN: We performed a multicentre case-control study assessing the medical records of adult patients diagnosed with proven TB with (TB/HS+) or without (TB/HS-) associated HS.RESULTS: Twenty-one patients with TB/HS+ (24% women, median age, 37 years [IQR 30-48]) were included in the study. Eleven patients (52%) were infected with human immunodeficiency virus and seven patients (33%) were immunocompromised due to other reasons. TB was disseminated in 17 patients (81%). Compared with 50 control TB patients (TB/HS-), patients with TB/HS+ were more likely to be immunocompromised (86% vs. 18%; P < 0.001) and to present with disseminated TB (80% vs. 12%; P < 0.001). The outcome was poorer in patients with TB/HS+, with a higher admission rate to intensive care (71% vs. 0%; P < 0.001) and a higher risk of death (38% vs. 7%; P = 0.005).CONCLUSION: TB/HS+ occurred more likely in immunocompromised patients and severely impaired the prognosis of TB. Further studies are needed to devise therapeutic strategies for patients with TB/HS+.

BACKGROUND: Although patients with advanced or metastatic lung cancer have poor prognosis, admission to the ICU for management of life-threatening complications has increased over the years. Patients with newly diagnosed lung cancer appear as good candidates for ICU admission, but more robust information to assist decisions is lacking. The aim of our study was to evaluate the prognosis of newly diagnosed unresectable lung cancer patients. METHODS: A retrospective multicentric study analyzed the outcome of patients admitted to the ICU with a newly diagnosed lung cancer (diagnosis within the month) between 2010 and 2013. RESULTS: Out of the 100 patients, 30 had small cell lung cancer (SCLC) and 70 had non-small cell lung cancer. (Thirty patients had already been treated with oncologic treatments.) Mechanical ventilation (MV) was performed for 81 patients. Seventeen patients received emergency chemotherapy during their ICU stay. ICU, hospital, 3- and 6-month mortality were, respectively, 47, 60, 67 and 71%. Hospital mortality was 60% when invasive MV was used alone, 71% when MV and vasopressors were needed and 83% when MV, vasopressors and hemodialysis were required. In multivariate analysis, hospital mortality was associated with metastatic disease (OR 4.22 [1.4-12.4]; p = 0.008), need for invasive MV (OR 4.20 [1.11-16.2]; p = 0.030), while chemotherapy in ICU was associated with survival (OR 0.23, [0.07-0.81]; p = 0.020). CONCLUSION: This study shows that ICU management can be appropriate for selected newly diagnosed patients with advanced lung cancer, and chemotherapy might improve outcome for patients with SCLC admitted for cancer-related complications. Nevertheless, tumors' characteristics, numbers and types of organ dysfunction should be taken into account in the decisional process before admitting these patients in ICU.
RESUMO
PURPOSE: Whether the quality of the ethical climate in the intensive care unit (ICU) improves the identification of patients receiving excessive care and affects patient outcomes is unknown. METHODS: In this prospective observational study, perceptions of excessive care (PECs) by clinicians working in 68 ICUs in Europe and the USA were collected daily during a 28-day period. The quality of the ethical climate in the ICUs was assessed via a validated questionnaire. We compared the combined endpoint (death, not at home or poor quality of life at 1 year) of patients with PECs and the time from PECs until written treatment-limitation decisions (TLDs) and death across the four climates defined via cluster analysis. RESULTS: Of the 4747 eligible clinicians, 2992 (63%) evaluated the ethical climate in their ICU. Of the 321 and 623 patients not admitted for monitoring only in ICUs with a good (n = 12, 18%) and poor (n = 24, 35%) climate, 36 (11%) and 74 (12%), respectively were identified with PECs by at least two clinicians. Of the 35 and 71 identified patients with an available combined endpoint, 100% (95% CI 90.0-1.00) and 85.9% (75.4-92.0) (P = 0.02) attained that endpoint. The risk of death (HR 1.88, 95% CI 1.20-2.92) or receiving a written TLD (HR 2.32, CI 1.11-4.85) in patients with PECs by at least two clinicians was higher in ICUs with a good climate than in those with a poor one. The differences between ICUs with an average climate, with (n = 12, 18%) or without (n = 20, 29%) nursing involvement at the end of life, and ICUs with a poor climate were less obvious but still in favour of the former. CONCLUSION: Enhancing the quality of the ethical climate in the ICU may improve both the identification of patients receiving excessive care and the decision-making process at the end of life.

PURPOSE: The objectives of our study were to describe the outcome of patients with malignancies treated for acute respiratory distress syndrome (ARDS) with noninvasive ventilation (NIV) and to evaluate factors associated with NIV failure. METHODS: Post hoc analysis of a multicenter database within 20 years was performed. All patients with malignancies and Berlin ARDS definition were included. Noninvasive ventilation use was defined as NIV lasting more than 1 hour, whereas failure was defined as a subsequent requirement of invasive ventilation. Conditional backward logistic regression analyses were conducted. RESULTS: A total of 1004 met the Berlin definition of ARDS. Noninvasive ventilation was used in 387 patients (38.6%) and NIV failure occurred in 71%, with an in-hospital mortality of 62.7%. Severity of ARDS defined by the partial pressure arterial oxygen and fraction of inspired oxygen ratio (odds ratio [OR], 2.20; 95% confidence interval [CI], 1.15-4.19), pulmonary infection (OR, 1.81; 95% CI, 1.08-3.03), and modified Sequential Organ Failure Assessment (SOFA) score (OR, 1.13; 95% CI, 1.06-1.21) were associated with NIV failure. Factors associated with hospital mortality were NIV failure (OR, 2.52; 95% CI, 1.56-4.07), severe ARDS as compared with mild ARDS (OR, 1.89; 95% CI, 1.05-1.19), and modified SOFA score (OR, 1.12; 95% CI, 1.05-1.19). CONCLUSION: Noninvasive ventilation failure in ARDS patients with malignancies is frequent and related to ARDS severity, SOFA score, and pulmonary infection-related ARDS. Noninvasive ventilation failure is associated with in-hospital mortality.

Reactive haemophagocytic syndrome (HS) is a rare condition that occurs in patients with infections, haematological malignancies or autoimmune diseases. Although various microorganisms are thought to trigger HS, most of the literature data on this topic have been gathered in single-centre case series. Here, we sought to characterize infectious triggers in a large, multicentre cohort of patients with HS. Patients were included in the present study if HS was solely due to one or more infections. Detailed microbiological data were recorded. Of the 162 patients with HS in the cohort, 40 (25%) had at least one infection and 38 of the latter (including 14 women, 36.8%) were included. The median age was 46 years. Seven patients were presumed to be immunocompetent (18.4%), whereas 19 patients (50%) were infected with human immunodeficiency virus and 12 patients (31.6%) were immunocompromised for other reasons. Twenty-seven patients (71.1%) had a single infection, whereas six (15.8%) and five (13.1%) patients had, respectively, two and three concomitant infections. We observed pyogenic bacterial infections (n = 7), tuberculosis (n = 10), non-tuberculous mycobacteriosis (n = 3), viral infections (n = 17: 11 cytomegalovirus, three Epstein-Barr virus, two human herpesvirus 8, one herpes simplex virus 2), parasitic infections (n = 8: four disseminated toxoplasmosis, one leishmaniasis, three malaria), fungal infections (n = 5: four pulmonary pneumocystosis and one candidaemia). Eighteen patients (47.4%) received corticosteroids and/or etoposide. Twelve patients died (31.6%). All multiple infections and all deaths occurred in immunocompromised patients. When compared with patients suffering from malignancy-associated HS, patients with infection-triggered HS were younger and more likely to be immunocompromised, and had a better outcome.

AIM: Low survival rate was previously described after cardiac arrest in cancer patients and may challenge the appropriateness of intensive care unit (ICU) admission after return of spontaneous circulation (ROSC). Objectives of this study were to report outcome and characteristics of cancer patients admitted to the ICU after cardiac arrest. METHODS: A retrospective chart review in seven medical ICUs in France, in 2002-2012. We studied consecutive patients with malignancies admitted after out-of-hospital cardiac arrest (OHCA) or in-hospital cardiac arrest (IHCA). RESULTS: Of 133 included patients of whom 61% had solid tumors, 48 (36%) experienced OHCA and 85 (64%) IHCA. Cardiac arrest was related to the malignancy or its treatment in 47% of patients. Therapeutic hypothermia was used in 51 (41%) patients. The ICU mortality rate was 98/133 (74%). Main causes of ICU death were refractory shock or multiple organ failure (n = 64, 48%) and neurological injury (n = 27, 20%); 42 (32%) patients died in ICU after treatment-limitation decisions. Twenty-four (18%) patients were discharged alive from the hospital. Overall 6-month survival rate was 14% (18/133, 95% confidence interval, 8-21%). Survival rates at ICU discharge and after 6 months did not differ significantly across type of malignancy or between the OHCA and IHCA groups, and neither were they significantly different from those in matched controls who had cardiac arrest but no malignancy. CONCLUSIONS: Even if low, the 6-month survival rate of 14% observed in cancer patients admitted to the ICU after cardiac arrest and ROSC may support the admission of these patients to the ICU and may warrant an initial full-code ICU management.

Intensive care unit (ICU) admission is associated with high mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Whether mortality has decreased recently is unknown. The 497 adult allogeneic HSCT recipients admitted to three ICUs between 1997 and 2011 were evaluated retrospectively. Two hundred and nine patients admitted between 1997 and 2003 were compared with the 288 patients admitted from 2004 to 2011. Factors associated with 90-day mortality were identified. The recent cohort was characterized by older age, lower conditioning intensity, and greater use of peripheral blood or unrelated-donor graft. In the recent cohort, ICU was used more often for patients in hematological remission (67% vs 44%; P<0.0001) and without GVHD (73% vs 48%; P<0.0001) or invasive fungal infection (85% vs 73%; P=0.0003) despite a stable admission rate (21.7%). These changes were associated with significantly better 90-day survival (49% vs 31%). Independent predictors of hospital mortality were GVHD, mechanical ventilation (MV) and renal replacement therapy (RRT). Among patients who required MV or RRT, survival was 29% and 18%, respectively, but dropped to 18% and 6% in those with GVHD. The use of ICU admission has changed and translated into improved survival, but advanced life support in patients with GVHD usually provides no benefits.

Hyperviscosity syndrome is a life-threatening complication. Clinical manifestations include neurological impairment, visual disturbance and bleeding. Measurement of plasma or serum viscosity by a viscometer assesses the diagnosis. Funduscopic examination is a key exam because abnormalities are well-correlated with abnormal plasma viscosity. Etiologies are various but symptomatic hyperviscosity is more common in Waldenström's macroglobulinemia and multiple myeloma. Prompt treatment is needed: treatment of the underlying disease should be considered, but generally not sufficient. Symptomatic measures aim to not exacerbate blood viscosity while urgent plasmapheresis effectively reduces the paraprotein concentration and relieves symptoms.

BACKGROUND: Data are scarce about ICU patients with malignancy and severe pulmonary embolism. Here, our main objective was to identify risk factors for life-threatening complications, organ failures, and death in ICU patients with severe pulmonary embolism, with special attention to the impact of malignancy. We also described the clinical features of PE in patients with and without malignancies. METHODS: Data from consecutive adults admitted to our ICU in 2002-2011 with severe pulmonary embolism were collected retrospectively. Multivariate analysis was performed to look for factors associated with death, organ failures, or life-threatening complications (major bleeding, recurrent PE, and cardiac arrest). RESULTS: Of 119 included patients (42 [35%] with bilateral pulmonary embolism), 41 had solid malignancies, 27 hematological malignancies, and 51 no malignancies. The most common symptoms were syncope (40%) and hemoptysis (18%) in patients with solid and hematological malignancies, respectively. Life-threatening complications occurred in 23 (19%) patients; risk factors were obesity (OR, 13.22; 1.93-90.70), disseminated intravascular coagulation/ischemic hepatitis (OR, 27.06; 5.14-142.46), fluid load ≥1000 mL/24 h (OR, 6.42; 1.60-25.76), and solid malignancy (OR, 5.45; 1.15-25.89). Inhospital mortality was 27/119 (23%) and respiratory or circulatory failure developed in 36 (30%) patients. Risk factors for these adverse outcomes were older age (OR, 1.04/year; 1.01-1.07), higher oxygen flow rate (OR, 1.28/L; 1.13-1.45); and renal failure (OR, 8.08; 2.50-26.11); whereas chest pain was protective (OR, 0.13; 0.04-0.48). CONCLUSION: In this study, solid malignancy was a risk factor for life-threatening complications but not for death.

PURPOSE: The prognosis of critically ill cancer patients has improved recently. Controversies remain as regard to the specific prognosis impact of neutropenia in critically ill cancer patients. The primary objective of this study was to assess hospital outcome of critically ill neutropenic cancer patients admitted into the ICU. The secondary objective was to assess risk factors for unfavorable outcome in this population of patients and specific impact of neutropenia. METHODS: We performed a post hoc analysis of a prospectively collected database. The study was carried out in 17 university or university-affiliated centers in France and Belgium. Neutropenia was defined as a neutrophil count lower than 500/mm(3). RESULTS: Among the 1,011 patients admitted into the ICU during the study period 289 were neutropenic at the time of admission. Overall, 131 patients died during their hospital stay (hospital mortality 45.3 %). Four variables were associated with a poor outcome, namely allogeneic transplantation (OR 3.83; 95 % CI 1.75-8.35), need for mechanical ventilation (MV) (OR 6.57; 95 % CI 3.51-12.32), microbiological documentation (OR 2.33; CI 1.27-4.26), and need for renal replacement therapy (OR 2.77; 95 % CI 1.34-5.74). Two variables were associated with hospital survival, namely age younger than 70 (OR 0.22; 95 % CI 0.1-0.52) and neutropenic enterocolitis (OR 0.37; 95 % CI 0.15-0.9). A case-control analysis was also performed with patients of the initial database; after adjustment, neutropenia was not associated with hospital mortality (OR 1.27; 95 % CI 0.86-1.89). CONCLUSION: Hospital survival was closely associated with younger age and neutropenic enterocolitis. Conversely, need for conventional MV, for renal replacement therapy, and allogeneic hematopoietic stem cell transplantation (HSCT) were associated with poor outcome.

Up to 25% of patients with profound neutropenia lasting for >10 days develop lung infiltrates, which frequently do not respond to broad-spectrum antibacterial therapy. While a causative pathogen remains undetected in the majority of cases, Aspergillus spp., Pneumocystis jirovecii, multi-resistant Gram-negative pathogens, mycobacteria or respiratory viruses may be involved. In at-risk patients who have received trimethoprim-sulfamethoxazole (TMP/SMX) prophylaxis, filamentous fungal pathogens appear to be predominant, yet commonly not proven at the time of treatment initiation. Pathogens isolated from blood cultures, bronchoalveolar lavage (BAL) or respiratory secretions are not always relevant for the etiology of pulmonary infiltrates and should therefore be interpreted critically. Laboratory tests for detecting Aspergillus galactomannan, ß-D-glucan or DNA from blood, BAL or tissue samples may facilitate the diagnosis; however, most polymerase chain reaction assays are not yet standardized and validated. Apart from infectious agents, pulmonary side-effects from cytotoxic drugs, radiotherapy or pulmonary involvement by the underlying malignancy should be included into differential diagnosis and eventually be clarified by invasive diagnostic procedures. Pre-emptive treatment with mold-active systemic antifungal agents improves clinical outcome, while other microorganisms are preferably treated only when microbiologically documented. High-dose TMP/SMX is first choice for treatment of Pneumocystis pneumonia, while cytomegalovirus pneumonia is treated primarily with ganciclovir or foscarnet in most patients. In a considerable number of patients, clinical outcome may be favorable despite respiratory failure, so that intensive care should be unrestrictedly provided in patients whose prognosis is not desperate due to other reasons.

BACKGROUND: Detailed information about lung cancer patients requiring admission to intensive care units (ICUs) is mostly restricted to single-center studies. Our aim was to evaluate the clinical characteristics and outcomes of lung cancer patients admitted to ICUs. PATIENTS AND METHODS: Prospective multicenter study in 449 patients with lung cancer (small cell, n = 55; non-small cell, n = 394) admitted to 22 ICUs in six countries in Europe and South America during 2011. Multivariate Cox proportional hazards frailty models were built to identify characteristics associated with 30-day and 6-month mortality. RESULTS: Most of the patients (71%) had newly diagnosed cancer. Cancer-related complications occurred in 56% of patients; the most common was tumoral airway involvement (26%). Ventilatory support was required in 53% of patients. Overall hospital, 30-day, and 6-month mortality rates were 39%, 41%, and 55%, respectively. After adjustment for type of admission and early treatment-limitation decisions, determinants of mortality were organ dysfunction severity, poor performance status (PS), recurrent/progressive cancer, and cancer-related complications. Mortality rates were far lower in the patient subset with nonrecurrent/progressive cancer and a good PS, even those with sepsis, multiple organ dysfunctions, and need for ventilatory support. Mortality was also lower in high-volume centers. Poor PS predicted failure to receive the initially planned cancer treatment after hospital discharge. CONCLUSIONS: ICU admission was associated with meaningful survival in lung cancer patients with good PS and non-recurrent/progressive disease. Conversely, mortality rates were very high in patients not fit for anticancer treatment and poor PS. In this subgroup, palliative care may be the best option.

Posaconazole (PSC) is currently recommended as primary prophylaxis in neutropenic patients with acute myeloid leukaemia (AML) and in allogenic haematopoietic stem cell transplantation (AHSCT) recipients with graft-versus-host disease (GVHD). Studies focusing on breakthrough invasive fungal disease (IFD) upon PSC prophylaxis show disparate results. In order to evaluate the incidence of IFD in patients on PSC prophylaxis and identify IFD risk factors, we carried out a retrospective study of all consecutive patients on PP from January 2007 to December 2010 in our hospital. Breakthrough IFDs were identified from the database of the central pharmacy and the French administrative database (PMSI), registering final medical diagnoses of hospitalized patients. Medical data were reviewed to study proven or probable IFD, according to EORTC/MSG definition. PSC plasma concentrations (PPC) were also retrieved. Poisson models were used for statistical analysis. Two hundred and seventy-nine patients received PSC prophylaxis for a median duration of 1.4 months (range 0.2-17.9). Proven (n=6) or probable (n=3) IFDs were diagnosed in nine cases (3.2%). IFD incidence rate per 100 person-month was 1.65 (95% CI, 0.79-2.97). IFDs were candidaemia (Candida glabrata, n=2), pulmonary invasive aspergillosis (n=3), disseminated fusariosis (n=2) and pulmonary mucormycosis (n=2). Seven deaths were reported, directly related to IFD in three patients (33.3%). First dosage of PPC under 0.3 mg/L was the single significant risk factor for IFD (RR, 7.77; 95% CI, 1.30-46.5; p 0.025). Breakthrough IFD in patients receiving PSC prophylaxis is rare but associated with a poor outcome. Low PSC plasma concentrations are associated with an increased risk of IFD.

Pneumocystis jirovecii is the only fungus of its kind to be pathogenic in humans. It is primarily responsible for pneumonia (PJP). The key to understanding immune defences has focused on T-cells, mainly because of the HIV infection epidemic. Patients presenting with PJP all have a CD4 count below 200/mm(3). The introduction of systematic primary prophylaxis and the use of new anti-retroviral drugs have significantly reduced the incidence of this disease in the HIV-infected population, mainly in developed countries. The increasingly frequent use of corticosteroids, chemotherapy, and other immunosuppressive drugs has led to an outbreak of PJP in patients not infected by HIV. These patients presenting with PJP have more rapid and severe symptoms, sometimes atypical, leading to delay the initiation of a specific anti-infective therapy, sometimes a cause of death. However, the contribution of new diagnostic tools and a better understanding of patients at risk should improve their survival.

Acute respiratory failure (ARF) in cancer patients remains a frequent and severe complication, despite the general improved outcome over the last decade. The survival of cancer patients requiring ventilatory support in Intensive Care Unit (ICU) has dramatically improved over the last years. The diagnostic approach, including an invasive strategy using fiber optic bronchoscopy or a non-invasive strategy, must be effective to identify a diagnostic, as it is a crucial prognostic factor. The use of non-invasive ventilation (NIV) instead of invasive mechanical ventilation (IMV), has contributed to decrease mortality, but NIV has to be used in appropriate situations. Indeed, NIV failure (i.e., need for IMV) is deleterious. Classical prognostic factors are not relevant anymore. The number of organ failure at admission and over the first 7 ICU days governs outcomes. Ventilatory support can thus be included in different management contexts: full code management with unlimited use of life sustaining therapies, full code management for a limited period, no-intubation decision, or the use of palliative NIV. The objectives of this review article are to summarize the modified ARF diagnostic and therapeutic management, induced by improvements in both intensive care and onco-hematologic management and recent literature data.
