In relatives of patients dying in intensive care units (ICUs), inadequate team support can increase the prevalence of prolonged grief and other psychological harm. We aimed to evaluate whether a proactive communication and support intervention would improve relatives' outcomes.We undertook a prospective, multicentre, cluster randomised controlled trial in 34 ICUs in France, to compare standard care with a physician-driven, nurse-aided, three-step support strategy for families throughout the dying process, following a decision to withdraw or withhold life support. Inclusion criteria were relatives of patients older than 18 years with an ICU length of stay 2 days or longer. Participating ICUs were randomly assigned (1:1 ratio) into an intervention cluster and a control cluster. The randomisation scheme was generated centrally by a statistician not otherwise involved in the study, using permutation blocks of non-released size. In the intervention group, three meetings were held with relatives: a family conference to prepare the relatives for the imminent death, an ICU-room visit to provide active support, and a meeting after the patient's death to offer condolences and closure. ICUs randomly assigned to the control group applied their best standard of care in terms of support and communication with relatives of dying patients. The primary endpoint was the proportion of relatives with prolonged grief (measured with PG-13, score ≥30) 6 months after the death. Analysis was by intention to treat, with the bereaved relatives as the unit of observation. The study is registered with ClinicalTrials.gov, NCT02955992.Between Feb 23, 2017, and Oct 8, 2019, we enrolled 484 relatives of ICU patients to the intervention group and 391 to the control group. 379 (78%) relatives in the intervention group and 309 (79%) in the control group completed the 6-month interview to measure the primary endpoint. The intervention significantly reduced the number of relatives with prolonged grief symptoms (66 [21%] vs 57 [15%]; p=0·035) and the median PG-13 score was significantly lower in the intervention group than in the control group (19 [IQR 14-26] vs 21 [15-29], mean difference 2·5, 95% CI 1·04-3·95).Among relatives of patients dying in the ICU, a physician-driven, nurse-aided, three-step support strategy significantly reduced prolonged grief symptoms.French Ministry of Health.

Also written with the NUTRIREA-3 Trial Investigators and the Clinical Research in Intensive Care and Sepsis (CRICS-TRIGGERSEP) Group; International audience; BackgroundThe optimal calorie and protein intakes at the acute phase of severe critical illness remain unknown. We hypothesised that early calorie and protein restriction improved outcomes in these patients, compared with standard calorie and protein targets.MethodsThe pragmatic, randomised, controlled, multicentre, open-label, parallel-group NUTRIREA-3 trial was performed in 61 French intensive care units (ICUs). Adults (≥18 years) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned to early nutrition (started within 24 h after intubation) with either low or standard calorie and protein targets (6 kcal/kg per day and 0·2–0·4 g/kg per day protein vs 25 kcal/kg per day and 1·0–1·3 g/kg per day protein) during the first 7 ICU days. The two primary endpoints were time to readiness for ICU discharge and day 90 all-cause mortality. Key secondary outcomes included secondary infections, gastrointestinal events, and liver dysfunction. The trial is registered on ClinicalTrials.gov, NCT03573739, and is completed.FindingsOf 3044 patients randomly assigned between July 5, 2018, and 8 Dec 8, 2020, eight withdrew consent to participation. By day 90, 628 (41·3%) of 1521 patients in the low group and 648 (42·8%) of 1515 patients in the standard group had died (absolute difference –1·5%, 95% CI –5·0 to 2·0; p=0·41). Median time to readiness for ICU discharge was 8·0 days (IQR 5·0–14·0) in the low group and 9·0 days (5·0–17·0) in the standard group (hazard ratio [HR] 1·12, 95% CI 1·02 to 1·22; p=0·015). Proportions of patients with secondary infections did not differ between the groups (HR 0·85, 0·71 to 1·01; p=0·06). The low group had lower proportions of patients with vomiting (HR 0·77, 0·67 to 0·89; p

Chimeric antigen receptor (CAR) T-cell therapy is a promising immunotherapeutic treatment concept that is changing the treatment approach to hematologic malignancies. The development of CAR T-cell therapy represents a prime example for the successful bench-to-bedside translation of advances in immunology and cellular therapy into clinical practice. The currently available CAR T-cell products have shown high response rates and long-term remissions in patients with relapsed/refractory acute lymphoblastic leukemia and relapsed/refractory lymphoma. However, CAR T-cell therapy can induce severe life-threatening toxicities such as cytokine release syndrome, neurotoxicity, or infection, which require rapid and aggressive medical treatment in the intensive care unit setting. In this review, the authors provide an overview of the state-of-the-art in the clinical management of severe life-threatening events in CAR T-cell recipients. Furthermore, key challenges that have to be overcome to maximize the safety of CAR T cells are discussed.

Treatment with CAR-T cells represents an innovative therapeutic advance in patients with refractory hematological malignancies. Infectious complications must always be considered and empirically treated. Specific complications such as cytokine release syndrome (CRS) and neurotoxicity can be severe and patients often require intensive care unit admission. A close monitoring is necessary in these patients. While CRS treatment is based on the administration of anti-IL-6 receptor (tocilizumab) in mild forms, corticosteroids are recommended in severe CRS and/or neurotoxicity

OBJECTIVES To assess whether critically ill hematologic patients without diagnosis of hemophagocytic lymphohistiocytosis may have features mimicking hemophagocytic lymphohistiocytosis according to both diagnostic scores. DESIGN A retrospective case-control study. SETTING Hemophagocytic syndrome diagnosis was standardized and based on a consensual diagnosis by at least two experts of a university hospital which is a reference center for hemophagocytic syndrome. PATIENTS Cases (hemophagocytic syndrome+) consisted in a group of consecutive patients (n = 150) admitted in our ICU between 2007 and 2018. Control group (hemophagocytic syndrome-) consisted in patients included in a prospective multicenter cohort of hematologic patients in whom three independent experts ruled out the diagnosis of hemophagocytic syndrome (n = 1011). MEASUREMENTS AND MAIN RESULTS Overall, 1,161 patients were included. Hospital mortality was 45.8% in hemophagocytic syndrome- patients (n = 66) and 38.8% in control patients (n = 392; p = 0.126). Median HScore was 235 (205-262) in hemophagocytic syndrome+ and 42 (18-62) in hemophagocytic syndrome- patients (p < 0.001); number of hemophagocytic lymphohistiocytosis criteria was 4 (4-5) vs 1 (0-1), respectively (p < 0.001). Diagnostic performances of both scores were excellent with area under receiver operating characteristic curve of 0.99 (95% CI, 0.99-0.99) and 0.99 (95% CI, 0.99-0.99) for hemophagocytic lymphohistiocytosis and HScore, respectively. After propensity score matching (n = 144 × 2), the median HScore was 234 (205-262) in hemophagocytic syndrome+ patients versus 49 (18-71) in hemophagocytic syndrome- patients (p < 0.001). Median number of hemophagocytic lymphohistiocytosis criteria was 4 (4-5) in hemophagocytic syndrome+ and 1 (0-1) in hemophagocytic syndrome- patients (p < 0.001). Area under receiver operating characteristic curve was then of 0.98 (95% CI, 0.96-0.99) for hemophagocytic lymphohistiocytosis criteria and 0.99 (95% CI, 0.99-1) for HScore. CONCLUSIONS In ICU patients, several conditions share some similarities with hemophagocytic syndrome, explaining the poor predictive value of isolated biological markers such as ferritin level. Despite these potential confounding factors, our study suggests HScore and hemophagocytic lymphohistiocytosis criteria to be highly discriminant identifying hemophagocytic syndrome in critically ill patients.

Summary Background Chimeric antigen receptor (CAR) T-cell therapy can induce side-effects such as cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome (ICANS), which often require intensive care unit admission. The aim of this study was to describe management of critically ill CAR T-cell recipients in intensive care. Methods This international, multicentre, observational cohort study was done in 21 intensive care units in France, Spain, the USA, the UK, Russia, Canada, Germany, and Austria. Eligible patients were aged 18 years or older; had received CAR T-cell therapy in the past 30 days; and had been admitted to intensive care for any reason. Investigators retrospectively included patients admitted between Feb 1, 2018, and Feb 1, 2019, and prospectively included patients admitted between March 1, 2019, and Feb 1, 2020. Demographic, clinical, laboratory, treatment, and outcome data were extracted from medical records. The primary endpoint was 90-day mortality. Factors associated with mortality were identified using a Cox proportional hazard model. Findings 942 patients received CAR T-cell therapy, of whom 258 (27%) required admission to intensive care and 241 (26%) were included in the analysis. Admission to intensive care was needed within median 4·5 days (IQR 2·0–7·0) of CAR T-cell infusion. 90-day mortality was 22·4% (95% CI 17·1–27·7; 54 deaths). At initial evaluation on admission, isolated cytokine release syndrome was identified in 101 patients (42%), cytokine release syndrome and ICANS in 93 (39%), and isolated ICANS in seven (3%) patients. Grade 3–4 cytokine release syndrome within 1 day of admission to intensive care was found in 50 (25%) of 200 patients and grade 3–4 ICANS in 38 (35%) of 108 patients. Bacterial infection developed in 30 (12%) patients. Life-saving treatments were used in 75 (31%) patients within 24 h of admission to intensive care, primarily vasoactive drugs in 65 (27%) patients. Factors independently associated with 90-day mortality by multivariable analysis were frailty (hazard ratio 2·51 [95% CI 1·37–4·57]), bacterial infection (2·12 [1·11–4·08]), and lifesaving therapy within 24 h of admission (1·80 [1·05–3·10]). Interpretation Critical care management is an integral part of CAR T-cell therapy and should be standardised. Studies to improve infection prevention and treatment in these high-risk patients are warranted. Funding Groupe de Recherche Respiratoire en Reanimation Onco-Hematologique.

International audience; Reactive hemophagocytic lymphohistiocytosis (rHLH) management requires early recognition, trigger identification, and adequate treatment in order to reduce mortality. We assessed the diagnostic yield of tissue biopsies to identify trigger in severe rHLH. We included all consecutive patients presenting an rHLH diagnosis (HLH-2004 criteria) admitted to the intensive care unit (ICU) of a tertiary hospital. This retrospective diagnostic accuracy study was conducted according to the Standards for Reporting Diagnostic Accuracy Statement. Among the 134 included patients (median age 47 years [IQR 47-56]), an underlying immunodeficiency was previously known in 61.2%. rHLH trigger was identified in 127 patients (94.8%) (hematological disorder 75%, infection 16%, systemic disease 4%). Diagnostic yield of tissue biopsies was as follows: lymph node 75% (95% confidence interval [CI], 61-85), skin 50% (95% CI, 27-73), bone marrow 44% (95% CI, 34-55), liver 30% (95% CI, 15-49). Splenectomy (yield 77%; 95% CI, 46-95) was reserved to cases of diagnostic deadlock. Procedural severe adverse events included two cases of reversible hemorrhagic shock. Seventy-eight percent of patients received etoposide regarding to the rHLH severity, and 68% could receive trigger-specific treatment in the ICU. A comprehensive diagnostic workup led to an rHLH trigger identification in 95% of patients, allowing prompt initiation of appropriate therapy. Prospective studies to validate a standardized diagnostic approach are warranted.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe condition that can lead patients to the intensive care unit. HLH diagnosis may be challenging, as it relies on sets of aspecific criteria. Several organ dysfunctions have been described during HLH, including hemostasis impairment found in more than half of the patients. The most frequently reported anomaly is a decrease in the fibrinogen level, which has been associated with higher mortality rates. Coagulation impairment study in patients with HLH represents an interesting field of research, as little is known about the mechanism leading to hypofibrinogenemia.

Rationale Acute respiratory failure (ARF) in patients admitted to the intensive care unit (ICU) with known or de novo small-vessel vasculitis (Svv) may be secondary to the underlying immune disease or to other causes. Early identification of the cause of ARF is essential to initiate the most appropriate treatment in a timely fashion. Methods A retrospective multicenter study in 10 French ICUs from January 2007 to January 2018 to assess the clinical presentation, main causes and outcome of ARF associated with Svv, and to identify variables associated with non-immune etiology of ARF in patients with known Svv. Results During the study period, 121 patients [62 (50–75) years; 62% male; median SAPSII and SOFA scores 39 (27–52) and 6 (4–8), respectively] were analyzed. An immune cause was identified in 67 (55%), and a non-immune cause in 54 (45%) patients. ARF was associated with several causes in 43% (n = 52) of cases. The main immune cause was diffuse alveolar hemorrhage (DAH) (n = 47, 39%), whereas the main non-immune cause was pulmonary infection (n = 35, 29%). The crude 90-day and 1-year mortality were higher in patients with non-immune ARF, as compared with their counterparts (32% and 38% vs. 15% and 20%, respectively; both p = 0.03), but was marginally significantly higher after adjusted analysis in a Cox model (p = 0.053). Among patients with a known Svv (n = 70), immunosuppression [OR 9.41 (1.52–58.3); p = 0.016], and a low vasculitis activity score [0.84 (0.77–0.93)] were independently associated with a non-immune cause, after adjustment for the time from disease onset to ARF, time from respiratory symptoms to ICU admission, and severe renal failure. Conclusions An extensive diagnosis workup is mandatory in ARF revealing or complicating Svv. Non-immune causes are involved in 43% of cases, and their short and mid-term prognosis may be poorer than those of immune ARF. Readily identified predictive factors of a non-immune cause could help avoiding unnecessary immunosuppressive therapies.

Hemophagocytic syndrome (HS) is a rare life-threatening condition that can lead to multi organ failure and shock. Acute circulatory failure in these patients has been poorly studied. Objectives of this study were to describe characteristics of HS patients with shock, prognostic factors and impact of etoposide infusion on hemodynamic parameters. This is a monocenter, retrospective, observational cohort study in a French tertiary intensive care unit (ICU). All adult critically ill patients with HS managed in the ICU between 2007 and 2017, requiring vasopressors (norepinephrine) and etoposide infusion.Thirty-four patients were included. Two-third (n = 25) were of male gender and median age was 48 years [IQR 34-62]. Shock (n = 14, 41%) and acute respiratory failure (n = 8, 23.5%) were the main initial reasons for ICU admission. The most common HS trigger was underlying hematological malignancy (n = 26; 76%), followed by infectious diseases in 3 patients (9%) and auto immune diseases in 2 (6%) patients. Median SOFA score at ICU admission was 14 [10-17]. A majority of patients required mechanical ventilation (n = 29, 85%) and initial median lactate level was 3.7 mmol/L [2.9-6.9]. Hospital mortality rate was 53% (n = 18) and was associated with SOFA score and renal replacement therapy in univariate analysis. All patients received broad spectrum antibiotics under suspicion of septic shock. In 17 patients, 21 nosocomial infections were documented, mainly from bacterial origin. Etoposide infusion was followed by decreased norepinephrine doses despite an increase in lactate level, while no degradation in mean arterial pressure, heart rate or renal function were identified.Hospital mortality remains high in critically ill HS patients with shock, but a significant improvement of hemodynamic parameters is observed following etoposide infusion, suggesting that an aggressive initial supportive care is crucial in these patients.

OBJECTIVES To describe short- and long-term neurologic prognosis of patients with thrombotic thrombocytopenic purpura and to identify clusters associated with evolution. DESIGN Prospective French cohort. SETTING ICU in a reference center. PATIENTS All consecutive patients with newly diagnosed thrombocytopenic purpura. INTERVENTION Comprehensive clinical, biological, and radiological evaluation at admission. Neurocognitive recovery was assessed using Glasgow Outcome Scale (range 1-5, with 1 representing death and 5 representing no or minimal neurologic deficit). MEASUREMENTS AND MAIN RESULTS Among the 130 newly diagnosed patients with thrombocytopenic purpura, 108 (83%; age 43 [30-52]; 73% women) presented with neurologic signs, including headaches (51%), limb weakness, paresthesia, and/or aphasia (49%), pyramidal syndrome (30%), decreased consciousness (20%), seizure (19%), cognitive impairment (34%), cerebellar syndrome (18%), and visual symptoms (20%). A hierarchical cluster analysis identified three distinct groups of patients. Cluster 1 included younger patients (37 [27-48], 41 [32-52], and 48 [35-54], in clusters 1, 2 and 3, respectively; p = 0.045), with a predominance of headaches (75%, 27%, and 36%; p < 0.0001). Cluster 2 patients had ataxic gait and cerebellar syndrome (77%, 0%, and 0%; p < 0.0001) and dizziness (50%, 0%, and 0%; p < 0.0001). Cluster 3 included patients with delirium (36%, 0%, and 9%; p < 0.0001), obtundation (58%, 0%, and 24%; p < 0.0001), and seizure (36%, 0%, and 14%; p < 0.0001). Acute kidney injury was 32%, 68%, and 77%, in clusters 1, 2, and 3, respectively (p < 0.0001). The three clusters did not differ for other biological or brain imaging. After a median follow-up of 34 months (12-71 mo), 100 patients (93%) were alive with full neurocognitive recovery (i.e., Glasgow Outcome Scale score 5) in 89 patients (89%). Patients from cluster 1 more frequently exhibited full recovery (Glasgow Outcome Scale score of 5) compared with clusters 2 and 3, (44 [98%], 13 [65%], and 21 [60%] at 3 mo; p < 0.0001), (44 [100%], 15 [68%], and 23 [69%] at 6 mo; p < 0.0001), and (40 [100%], 15 [79%], and 20 [57%] at 1 yr; p < 0.0001). CONCLUSIONS Initial clinical neurologic evaluation in thrombocytopenic purpura patients distinguishes three groups of patients with different clinical and functional outcomes.

International audience; In the non-AIDS group, several underlying conditions and immune defects could lead to different PCP presentations. This study compared PCP presentation and outcome according to the underlying disease. A secondary analysis of a previously published prospective observational study including 544 PCP patients was done. Only non-AIDS patients were included. Underlying disease was defined as chronic lymphocytic leukemia (CLL), organ transplantation, solid cancer, allogeneic hematopoietic stem cell transplant (AHSCT), other hematological diseases, and immunosuppressive treatment. Clinical characteristics and outcomes were compared between groups. Multiple correspondent analyses compared clinical characteristics at diagnosis. Day 30 mortality was analyzed. Three hundred and twenty-one patients were included in the study. The underlying diseases were hematological malignancy (n = 75), AHSCT (n = 14), CLL (n = 19), solid organ transplant (n = 94), solid tumor (n = 39), and immunosuppressive treatment (n = 57). Compared with other underlying diseases, PCP related to CLL was closer to PCP related to AIDS presentation (long duration of symptoms before diagnosis, high level of dyspnea, and low oxygen saturation at diagnosis). Day 30 mortality was associated with underlying disease, oxygen flow, and shock at ICU admission. PCP presentations may vary according to the underlying reason for immunosuppression. Response to treatment and adjuvant steroid therapy should be analyzed regarding this result.

OBJECTIVES Acute kidney injury, acute kidney injury severity, and acute kidney injury duration are associated with both short- and long-term outcomes. Despite recent definitions, only few studies assessed pattern of renal recovery and time-dependent competing risks are usually disregarded. Our objective was to describe pattern of acute kidney injury recovery, change of transition probability over time and their risk factors. DESIGN Monocenter retrospective cohort study. Acute kidney injury was defined according to Kidney Disease Improving Global Outcomes definition. Renal recovery was defined as normalization of both serum creatinine and urine output criteria. Competing risk analysis, time-inhomogeneous Markov model, and group-based trajectory modeling were performed. SETTING Monocenter study. PATIENTS Consecutive patients admitted in ICU from July 2018 to December 2018 were included. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Three-hundred fifty patients were included. Acute kidney injury occurred in 166 patients at ICU admission, including 64 patients (38.6%) classified as acute kidney disease according to Acute Disease Quality Initiative definition and 44 patients (26.5%) who could not be classified. Cumulative incidence of recovery was 25 % at day 2 (95% CI, 18-32%) and 35% at day 7 (95% CI, 28-42%). After adjustment, need for mechanical ventilation (subdistribution hazard ratio, 0.42; 95% CI, 0.23-0.74) and severity of the acute kidney injury (stage 3 vs stage 1 subdistribution hazard ratio, 0.11; 95% CI, 0.03-0.35) were associated with lack of recovery. Group-based trajectory modeling identified three clusters of temporal changes in this setting, associated with both acute kidney injury recovery and patients' outcomes. CONCLUSIONS In this study, we demonstrate Acute Disease Quality Initiative to allow recovery pattern classification in 75% of critically ill patients. Our study underlines the need to take into account competing risk factors when assessing recovery pattern in critically ill patients.

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy secondary to a severely decreased A Disintegrin And Metalloprotease with ThromboSpondin type 1 repeats 13 (ADAMTS13) activity, resulting in the formation of widespread von Willebrand factor - and platelet-rich microthrombi. ADAMTS13 deficiency is mainly acquired through anti-ADAMTS13 autoantibodies in adults. With modern standards of care, unresponsive TTP has become rarer with a frequency of refractory/relapsing forms dropping from >40% to

Objective Prognostic impact of early ICU admission remains controversial. The aim of this review was to investigate the impact of early ICU admission in the general ICU population and in critically ill cancer patients and to report level of evidences of this later. Methods Systematic review and meta-analysis performed on articles published between 1970 and 2017. Two authors extracted data. Influence of early ICU admission on mortality is reported as Risk Ratio (95%CI) using both fixed and random-effects model. Data synthesis For general ICU population, 31 studies reporting on 73,213 patients were included (including 66,797 patients with early ICU admission) and for critically ill cancer patients 14 studies reporting on 2414 patients (including 1272 with early ICU admission) were included. Early ICU admission was associated with decreased mortality using a random effect model (RR 0.65; 95% confidence interval 0.58–0.73; I2 = 66%) in overall ICU population as in critically ill cancer patients (RR 0.69; 95% confidence interval 0.52–0.90; I2 = 85%). To explore heterogeneity, a meta-regression was performed. Characteristics of the trials (prospective vs. retrospective, monocenter vs. multicenter) had no impact on findings. Publication after 2010 (median publication period) was associated with a lower effect of early ICU admission (estimate 0.37; 95%CI 0.14–0.60; P = 0.002) in the general ICU population. A significant publication bias was observed. Conclusion Theses results suggest that early ICU admission is associated with decreased mortality in the general ICU population and in CICP. These results were however obtained from high risk of bias studies and a high heterogeneity was noted. Systematic review registration: PROSPERO 2018 CRD42018094828.

Background Mucormycosis is an emerging fungal infection that may lead to multi-organ failure, especially in patients with hematological malignancies (HM). We performed a retrospective, cohort study, in five intensive care units (ICU) to assess the outcome of critically ill patients with HM and mucormycosis between 2002 and 2018. The secondary objective was to identify prognostic factors in this setting. Results Twenty-six patients were included with a median age of 38 years [IQR, 26–57]). Acute leukemia was the most frequent underlying disease (50%). Nine patients (35%) underwent allogeneic stem cell transplantation (SCT). Nineteen patients (73%) had neutropenia and 16 (62%) had received steroids. The main reason for admission was acute respiratory failure (n = 14, 54%) followed by shock (n = 5 19%). The median SOFA score at admission was 7 [5–8]. According to EORTC/MSG criteria, mucormycosis was "proven" in 14 patients (54%), "probable" in 5 (19%) and “possible” in 7 (27%) in whom diagnosis was made by qPCR. Rhizopus and Mucor were the most frequent documented species. Seven patients (27%) had concurrent Aspergillus infection. Mucormycosis was diagnosed 1 day [−4 to + 6] after ICU admission. Sixteen patients (62%) had pulmonary involvement and ten (38%) rhino-cerebral involvement. Infection was disseminated in eight patients (31%). Twenty-two patients (85%) were treated with liposomal amphotericin B; 12 (46%) received antifungal combination including posaconazole in 7. Eight patients (31%) underwent curative surgery. Twenty-one patients (81%) required invasive mechanical ventilation (IMV), 18 (69%) vasopressors, and 9 (35%) renal replacement therapy. ICU and hospital mortality rates were 77% and 88%, respectively. The median overall survival was 9 days [3–22]. IMV was strongly associated with ICU mortality (p Conclusions Mucormycosis is associated with a high mortality rate in patients with HM, especially in allogeneic SCT recipients. Benefit of ICU management in these patients should be assessed before admission and strategies aiming to improve these patients’ outcome are urgently needed.

Early thrombotic thrombocytopenic purpura (TTP) recognition is critical as this disease is almost always lethal if not treated promptly with therapeutic plasma exchanges. Currently, as ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) activity is not widely available in emergency, scores have been developed to help differentiating TTP from other thrombotic microangiopathies (TMAs). The aim of this work was to study the accuracy of these diagnostic scores in the intensive care unit (ICU) setting. Performance of both Coppo and PLASMIC scores was studied in a cohort of adult TMA patients requiring admission to one university hospital ICU from 2006 to 2017. Receiver operating characteristic (ROC) curves were established, and confidence intervals of the area under the curve (AUC) were determined. Multivariate logistic regression analysis was performed to identify parameters specifically associated with TTP, to compare diagnostic scores and to elaborate more accurate diagnostic models. During the study period, 154 TMA patients required ICU admission, including 99 (64.2%) TTP and 55 (35.7%) non-TTP patients. AUC under the ROC curve in predicting TTP was 0.86 (95% confidence interval [CI]: 0.81–0.92) for the Coppo score, 0.67 (95% CI: 0.58–0.76) for the PLASMIC score, and 0.86 (95% CI: 0.81–0.92) for platelet count alone. Platelet count ≤20 G/L, determined as the best cut-off rate for thrombocytopenia, performed similarly to the Coppo score and better than the PLASMIC score to differentiate TTP from non-TTP patients, both using AUC ROC curve and logistic regression. In a monocentric cohort of TMA patients requiring ICU admission, the PLASMIC score had limited performance for the diagnosis of TTP. The performance of the Coppo score was good but similar to a single highly discriminant item: platelet count ≤20 G/L at admission.

Sinusoidal obstruction syndrome (SOS) is a life-threatening liver complication of high- dose chemotherapy. Defibrotide is the only available therapeutic option approved for SOS. The prognosis of SOS in patients requiring intensive care unit (ICU) admission remains unknown. The primary objective of this study was to assess the outcome of SOS patients in ICU. This retrospective study was conducted between 2007 and 2019 in 13 French ICUs. Seventy-one critically ill adult patients with SOS defined according to European Society for Blood and Marrow Transplantation criteria and treated with defibrotide were included. The main reasons for ICU admission were respiratory failure and acute kidney injury. Mechanical ventilation, vasopressors, and renal replacement therapy were required in 59%, 52%, and 49% of patients, respectively. Twenty-three percent of patients experienced a bleeding event during defibrotide treatment. Hospital mortality was 54%, mainly related to multiorgan failure. Older age (hazard ratio [HR], 1.02; 95% confidence interval [CI], 1.00 to 1.04), mechanical ventilation (HR, 1.99; 95% CI, 1.00 to 3.99), renal replacement therapy (HR, 2.55; 95% CI, 1.32 to 4.91) were independent predictors of hospital mortality. Defibrotide prophylaxis (HR, 0.35; 95% CI, 0.13 to 0.92) was associated with better outcomes. Critically ill patients with SOS have a high mortality rate in the ICU, especially if organ support is required. Additional studies assessing the impact of defibrotide prophylaxis are warranted.

Hemophagocytic syndrome remains a rare but life-threatening complication and is associated with intensive care unit (ICU) admission. The pathophysiology is based on a defect of cytotoxicity in T cells that results in a state of hyperinflammation in the presence of a trigger. As a consequence, patients may develop multiorgan failure. The diagnosis of hemophagocytic syndrome (HS) remains difficult and relies on persistant high-grade fevers in the absence of infection and on constellation of laboratory parameters. However, prompt diagnosis and treatment (supportive care and specific treatment) are associated with improved outcome. Interaction with other specialists (hematologist, internist) may improve the diagnosis and treatment strategy. This article describes diagnostic tools, organ failures associated with HS, main etiologies, and management.

Le syndrome hémophagocytaire (SH) se présente classiquement sous la forme de cytopénies fébriles accompagnées d’un syndrome tumoral, le plus souvent dans le cadre d’un déficit immunitaire sous-jacent. Les formes les plus sévères s’accompagnent de défaillances d’organes qui peuvent conduire le patient en réanimation. Les principales étiologies de SH sont les infections, les hémopathies et les maladies de système. Les infections associées au SH sont majoritairement virales, liées à l’EBV, au CMV et aux autres virus du groupe herpes. Les infections bactériennes sont dominées par les mycobactéries, et les parasites sont essentiellement représentés par la leishmaniose et la toxoplasmose. Enfin, parmi les infections fongiques, l’histoplasmose est à rechercher en priorité. La prise en charge thérapeutique du SH associé aux infections comprend trois volets : le traitement de l’infection, les traitements de support et le traitement du SH. Les principaux traitements proposés dans le cadre du SH associé aux infections sont les corticoïdes, les immunoglobulines polyvalentes et l’étoposide. À la phase initiale, c’est principalement la gravité des patients (défaillances d’organes) qui guidera la décision d’administrer ou non un traitement spécifique du SH. Un aspect important de la prise en charge thérapeutique est la recherche systématique d’un déficit immunitaire sous-jacent, qui pourra faire l’objet d’une prise en charge spécifique. Le bilan minimal comprendra la recherche d’une infection par le VIH, la recherche d’une hémopathie lymphoïde sous-jacente (maladie de Hodgkin, lymphome non hodgkinien, maladie de Castleman) et la recherche d’arguments en faveur d’une maladie systémique (Lupus et maladie de Still).

Background Post-intensive care syndrome includes the multiple consequences of an intensive care unit (ICU) stay for patients and families. It has become a new challenge for intensivists. Prevention programs have been disappointing, except for ICU diaries, which report the patient’s story in the ICU. However, the effectiveness of ICU diaries for patients and families is still controversial, as the interpretation of the results of previous studies was open to criticism hampering an expanded use of the diary. The primary objective of the study is to evaluate the post-traumatic stress syndrome in patients. The secondary objectives are to evaluate the post-traumatic stress syndrome in families, anxiety and depression symptoms in patients and families, and the recollected memories of patients. Endpoints will be evaluated 3 months after ICU discharge or death. Methods A prospective, multicenter, randomized, assessor-blind comparative study of the effect of an ICU diary on patients and families. We will compare two groups: one group with an ICU diary written by staff and family and given to the patient at ICU discharge or to the family in case of death, and a control group without any ICU diary. Each of the 35 participating centers will include 20 patients having at least one family member who will likely visit the patient during their ICU stay. Patients must be ventilated within 48 h after ICU admission and not have any previous chronic neurologic or acute condition responsible for cognitive impairments that would hamper their participation in a phone interview. Three months after ICU discharge or death of the patient, a psychologist will contact the patient and family by phone. Post-traumatic stress syndrome will be evaluated using the Impact of Events Scale-Revised questionnaire, anxiety and depression symptoms using the Hospital Anxiety and Depression Scale questionnaire, both in patients and families, and memory recollection using the ICU Memory Tool Questionnaire in patients. The content of a randomized sample of diaries of each center will be analyzed using a grid. An interview of the patients in the intervention arm will be conducted 6 months after ICU discharge to analyze in depth how they use the diary. Discussion This study will provide new insights on the impact of ICU diaries on post-traumatic stress disorders in patients and families after an ICU stay.

Background Despite substantial improvements in the management of multiple myeloma, renal failure remains an important burden that tremendously impairs prognosis. The purpose of this study was to describe the characteristics and to establish prognostic factors of renal recovery in myeloma patients admitted to the intensive care unit (ICU) for acute kidney injury (AKI) Stage 3 treated with renal replacement therapy (RRT). Methods A retrospective single-centre cohort study was performed, including consecutive myeloma patients admitted to one medical ICU between 1 January 2007 and 1 September 2015 and treated with RRT. Patients were evaluated 60 days after initiation of RRT and divided into three groups: alive without dialysis, alive and dialysis-dependent or deceased. A univariate analysis was performed to identify factors associated with renal recovery (alive without dialysis 60 days after initiation of RRT). Results Fifty patients were included in the study. Mean age was 63 (interquartile range: 58-70) years and 32 (64%) were male. Patients were admitted to the ICU 4 (1-7) years after the diagnosis of myeloma. Twenty-one (42%) had already been treated with high-dose therapy combined with autologous stem cell transplantation. Baseline renal function evaluated by estimated glomerular filtration rate (GFR) before ICU admission was 63 (44-90) mL/min/1.73 m2. The mean SOFA score at Day 1 was 7 (4-8). The three main reasons for ICU admission were AKI (n = 31, 62%), acute pulmonary oedema (n = 17, 32%) and sepsis (n = 10, 20%). During ICU stay, RRT was implemented in all patients, 16 (32%) patients required invasive mechanical ventilation and 12 (24%) received vasopressors. The mean ICU and hospital length of stay were 6 (1-7) and 28 (13-34) days, respectively. At Day 60, 23 (46%) patients were alive without dialysis, 17 (32%) had died and 10 (20%) were still undergoing dialysis. Among the 23 patients who recovered, the mean duration of dialysis was 6 (2-18) days and renal function was not significantly different from baseline [estimated GFR at baseline = 65 (25-74) mL/min/1.73 m2 versus 63 (56-70) mL/min/1.73 m2 at Day 60, P = 0.70]. By univariate analysis, two factors were associated with nonrecovery of renal function at Day 60: a history of high-dose therapy combined with autologous stem cell transplantation [odds ratio (OR) = 6.1, 95% confidence interval (CI) 1.7-21.6; P = 0.008] and a proteinuria at ICU admission >370 mg/mmol creatinine (OR = 4.2, 95% CI 1.1-17; P = 0.02). None of the other variables related to the haematological malignancy or to the ICU stay was associated with renal recovery at Day 60. Conclusions AKI Stage 3 in critically ill myeloma patients was associated with a lower than expected hospital mortality. Patients with a high level of proteinuria and a history of high-dose therapy combined with autologous stem cell transplantation were less likely to recover their renal function at Day 60. Key words dialysis, intensive care, multiple myeloma, prognosis, proteinuria.

Background: Cuff leak test was developed to predict the occurrence of post-extubation stridor (PES). This study evaluated the diagnostic performance of this test in unselected critically ill patients. Methods: Multicenter prospective study including unselected ventilated patients at the time of their first planned extubation. The diagnostic performance of 4 different cuff leak tests was assessed. Results: Post-extubation stridor occurred in 34 (9.4%) of 362 included patients. Compared to patients without PES, patients with PES required more frequently reintubation (6 [17.6%] vs 26 [7.9%], P = .041), prolonged duration of ventilation (6 [3-13] vs 5 [2-9] days, P = .029), and longer intensive care unit (ICU) stay (12 [6-17.5] vs 7.5 [4-13] days, P = .018). However, ICU mortality was similar in both groups (1 [2.9%] vs 23 [7.0%], P = .61). The 4 cuff leak tests display poor diagnostic accuracy: sensitivities ranging from 27% to 46%, specificities from 70% to 88%, positive predictive values from 14% to 19%, and negative predictive values from 92% to 93%. Conclusion: Post-extubation stridor occurs in less than 10% of unselected critically ill patients. The several cuff leak tests display limited diagnostic performance for the detection of PES. Given the high rate of false positives, routine cuff leak test may expose to undue prolonged mechanical ventilation.

International audience; PURPOSE:Invasive pulmonary aspergillosis (IPA) is a dreadful event in patients with hematological malignancies (HM). Recent advances have standardized diagnostic, prophylactic and curative therapeutic strategies. We sought to assess whether these advances actually translate into improved survival in critically ill patients with acute respiratory failure and IPA.METHODS:This was a retrospective, multicenter study. Adult patients with HM, IPA, admitted to the ICU for acute respiratory failure over a 20-year period (January 1998-December 2017) were included. A cox regression model was used to identify variables independently associated with day-90 survival.RESULTS:Overall, 219 patients were included [138 (63%) men, median age 55 (IQR 44-64)]. Acute myeloid leukemia (30.1%) and non-Hodgkin lymphoma (22.8%) were the most frequent malignancies, and 53 (24.2%) were allogeneic stem cell recipients. Day-1 SOFA score was 9 [7-12]. Most patients presented with probable IPA, whereas 15 (7%) underwent lung biopsies or pleurocentesis and met criteria for proven IPA. Overall ICU and day-90 mortality were, respectively, 58.4% and 75.2% (80.4% if invasive mechanical ventilation) without any significant improvement over time. By multivariable analysis adjusted on day-1 SOFA score and ventilation strategies, voriconazole use (HR 0.49, CI 95 0.34-0.73, p

Outcomes in cancer patients after unplanned ICU admission was reassessed.retrospective cohort of patients with solid tumours admitted to ICU over a 10 years period.622 patients (age 62 [53-70]) were analysed. The most common primary sites of cancer were lung (n = 133; 21.4%) and digestive tract (n = 126; 20.2%) The ICU mortality rate was 22.2% (n = 138). Among 470 ICU survivors, the 1-year mortality was 41.3% (95% CI, 36-45.9) (n = 167). Factors independently associated with 1-year mortality were ICU admission after 2010 (HR 0.53 (0.37-0.76), p .001), disease status (respectively, HR = 1.88 (1.0.2-3.45), p = .002) for locally advanced cancer and HR = 2.23 (1.35-3.67), p = .003) for metastatic cancer), poor performance status (HR = 1.58 (1.08-2.31), p = .019), newly diagnosed cancer at ICU admission (HR = 2.02 (1.28-3.20), p = .003), inability to receive oncologic treatment after ICU discharge (HR = 5.34 (3.49-8.18), p .001) and decision to withhold life-sustaining treatment during ICU stay (HR = 2.34 (1.50-3.65), p .001).Among the factors associated with one-year mortality after ICU discharge, the possibility of receiving oncologic treatment after ICU discharge seems crucial.
