Multicenter Retrospective Study of Invasive Fusariosis in Intensive Care Units, France.

Invasive fusariosis can be life-threatening, especially in immunocompromised patients who require intensive care unit (ICU) admission. We conducted a multicenter retrospective study to describe clinical and biologic characteristics, patient outcomes, and factors associated with death and response to antifungal therapy. We identified 55 patients with invasive fusariosis from 16 ICUs in France during 2002----2020. The mortality rate was high (56%). Fusariosis-related pneumonia occurred in 76% of patients, often leading to acute respiratory failure. Factors associated with death included elevated sequential organ failure assessment score at ICU admission or history of allogeneic hematopoietic stem cell transplantation or hematologic malignancies. Neither voriconazole treatment nor disseminated fusariosis were strongly associated with response to therapy. Invasive fusariosis can lead to multiorgan failure and is associated with high mortality rates in ICUs. Clinicians should closely monitor ICU patients with a history of hematologic malignancies or stem cell transplantation because of higher risk for death.

Platelet transfusions in adult ICU patients with thrombocytopenia: A sub-study of the PLOT-ICU inception cohort study.

BACKGROUND: Platelet transfusions are frequently used in the intensive care unit (ICU), but current practices including used product types, volumes, doses and effects are unknown. STUDY DESIGN AND METHODS: Sub-study of the inception cohort study 'Thrombocytopenia and Platelet Transfusions in the ICU (PLOT-ICU)', including acutely admitted, adult ICU patients with thrombocytopenia (platelet count <150 × 109/L). The primary outcome was the number of patients receiving platelet transfusion in ICU by product type. Secondary outcomes included platelet transfusion details, platelet increments, bleeding, other transfusions and mortality. RESULTS: Amongst 504 patients with thrombocytopenia from 43 hospitals in 10 countries in Europe and the United States, 20.8% received 565 platelet transfusions; 61.0% received pooled products, 21.9% received apheresis products and 17.1% received both with a median of 2 (interquartile range 1-4) days from admission to first transfusion. The median volume per transfusion was 253 mL (180-308 mL) and pooled products accounted for 59.1% of transfusions, however, this varied across countries. Most centres (73.8%) used fixed dosing (medians ranging from 2.0 to 3.5 × 1011 platelets/transfusion) whilst some (mainly in France) used weight-based dosing (ranging from 0.5 to 0.7 × 1011 platelets per 10 kg body weight). The median platelet count increment for a single prophylactic platelet transfusion was 2 (-1 to 8) × 109/L. Outcomes of patients with thrombocytopenia who did and did not receive platelet transfusions varied. CONCLUSIONS: Among acutely admitted, adult ICU patients with thrombocytopenia, 20.8% received platelet transfusions in ICU of whom most received pooled products, but considerable variation was observed in product type, volumes and doses across countries. Prophylactic platelet transfusions were associated with limited increases in platelet counts.

Outcome of patients with newly diagnosed AML admitted to the ICU, including preemptive admission - a multi-center study.

Acute myeloid leukemia (AML) can lead to life-threatening complications that may require intensive care unit (ICU) management. It has been advocated that early preemptive (ePE) ICU admission, before the onset of organ failure, could benefit some high-risk patients such as those with hyperleukocytosis. The aim of this study was to retrospectively analyze the outcome of newly diagnosed AML patients who required ICU admission in five academic centers with a special focus on patients with an ePE admission strategy, i.e., those transferred to the ICU without any organ failure (modified SOFA score ≤ 2 [omitting thrombocytopenia] and no life-sustaining intervention in the first 24 h following ICU admission) before the start of induction therapy. Between January 2017 and December 2019, 428 patients were included among which 101 were admitted to the ICU. Among patients requiring life-sustaining interventions (n = 83), 18 (22%) died while in the ICU but ICU survivors had the same survival as those not admitted to the ICU. Patients with an ePE admission (n = 18) had more comorbidities and high-risk disease features such as hyperleukocytosis but required no life-sustaining interventions while in the ICU. In a subgroup analysis of patients with hyperleukocytosis ≥ 50 G/l at diagnosis (n = 85), patients not admitted to the ICU and those admitted with an ePE strategy had similar outcomes. This study provides encouraging results about ICU outcome in AML patients during induction therapy but the potential benefit of an ePE strategy must be confirmed prospectively.

Anticoagulation strategy and safety in critically ill COVID-19 patients: a French retrospective multicentre study.

BACKGROUND: Patients with critical illness due to COVID-19 exhibit increased coagulability associated with a high risk of venous thrombo-embolism (VTE). Data on prophylactic anticoagulation for these patients are limited and conflicting. The purpose of this study was to evaluate whether intermediate-dose prophylactic anticoagulation in patients with COVID-19 requiring ICU admission was associated with better outcomes compared to standard-dose prophylactic anticoagulation. METHODS: We retrospectively included adults admitted with severe COVID-19 to any of 15 ICUs, in 2020 or 2021. We compared the groups given intermediate-dose vs. standard-dose prophylactic anticoagulation. The primary outcome was all-cause day-90 mortality. Secondary outcomes were VTE (pulmonary embolism or deep vein thrombosis), ICU stay length, and adverse effects of anticoagulation. RESULTS: Of 1174 included patients (mean age, 63 years), 399 received standard-dose and 775 intermediate-dose prophylactic anticoagulation. Of the 211 patients who died within 90 days, 86 (21%) received intermediate and 125 (16%) standard doses. After adjustment on early corticosteroid therapy and critical illness severity, there were no significant between-group differences in day-90 mortality (hazard ratio [HR], 0.73; 95%CI, 0.52-1.04; p = 0.09) or ICU stay length (HR, 0.93; 95%CI, 0.79-1.10; p = 0.38). Intermediate-dose anticoagulation was significantly associated with fewer VTE events (HR, 0.55; 95%CI, 0.38-0.80; p < 0.001). Bleeding events occurred in similar proportions of patients in the two groups (odds ratio, 0.86; 95%CI, 0.50-1.47; p = 0.57). CONCLUSIONS: Mortality on day 90 did not differ between the groups given standard-dose and intermediate-dose prophylactic anticoagulation, despite a higher incidence of VTE in the standard-dose group.

Clinical features and outcomes of patients admitted to the ICU for Cyclophosphamide-associated cardiac toxicity: a retrospective cohort.

PURPOSE: To describe the management and outcome of critically-ill patients with Cyclophosphamide (CY)-associated cardiac toxicity. METHODS: All patients admitted to the intensive care units (ICUs) of the Nantes and Rennes University Hospitals for a CY-associated cardiac toxicity between January 2015 and December 2020 were included. RESULTS: Of the thirty-four patients included in the study, twenty-four (70%) underwent allogeneic hematopoietic stem cell transplantation (HSCT), four (12%) autologous HSCT, and six (18%) chemotherapy for hematological malignancies. Acute pulmonary edema (65%), cardiac arrest (9%), and cardiac arrhythmia (6%) were the most common reasons for ICU admission. Patients were admitted to the ICU 6.5 (4-12) days after the intravenous administration of a median dose of CY of 100 [60-101] mg/Kg. Echocardiographic findings showed moderate to severe left ventricular systolic dysfunction (69%) and pericardial effusion (52%). Eighteen (53%) patients ultimately developed cardiogenic shock and required vasopressors (47%) and/or inotropes (18%). Invasive mechanical ventilation and renal replacement therapy were required in twenty (59%) and five (14%) patients, respectively. Sixteen (47%) patients died of whom 12 (35.3%) died from refractory cardiogenic shock. The left ventricular ejection fraction improved over time in most survivors with a median time until full recovery of 33 (12-62) days. Two (11%) patients had a persistent left ventricular dysfunction at 6 months. CONCLUSION: Refractory cardiogenic shock is the primary cause of death of patients with severe CY-related cardiotoxicity. Nonetheless, the cardiac function of most survivors recovered within a month.

Epidemiology and Clinical Impact of Respiratory Coinfections at Diagnosis of Pneumocystis jirovecii Pneumonia.

BACKGROUND: The role of respiratory coinfections at diagnosis of Pneumocystis jirovecii pneumonia (PcP) on clinical impact has been underestimated. METHODS: A retrospective observational study was conducted January 2011 to April 2019 to evaluate respiratory coinfections at diagnosis of PcP patients in 2 tertiary care hospitals. Coinfection was defined by identification of pathogens from P. jirovecii-positive samples. RESULTS: Of 7882 respiratory samples tested for P. jirovecii during the 8-year study, 328 patients with diagnosis of PcP were included. Mean age was 56.7 (SD 14.9) years, 193 (58.8%) were male, 74 (22.6%) had positive HIV serology, 125 (38.1%) had viral coinfection, 76 (23.2%) bacterial coinfection, and 90-day mortality was 25.3%. In the overall population, 90-day mortality was independently associated with solid tumor underlying disease (odds ratio [OR], 11.8; 95% confidence interval [CI], 1.90-78.0; P = .008), sepsis-related organ failure assessment score (SOFA) at admission (OR, 1.62; 95% CI, 1.34-2.05; P< .001), and cytomegalovirus (CMV) respiratory coinfection (OR, 3.44; 95% CI, 1.24-2.90; P = .02). Among HIV-negative patients, respiratory CMV coinfection was associated with worse prognosis, especially when treated with adjunctive corticosteroid therapy. CONCLUSIONS: Respiratory CMV coinfection at PcP diagnosis was independently associated with increased 90-day mortality, specifically in HIV-negative patients.

Early steroids and ventilator-associated pneumonia in COVID-19-related ARDS.

RATIONALE: Early corticosteroid treatment is used to treat COVID-19-related acute respiratory distress syndrome (ARDS). Infection is a well-documented adverse effect of corticosteroid therapy. OBJECTIVES: To determine whether early corticosteroid therapy to treat COVID-19 ARDS was associated with ventilator-associated pneumonia (VAP). METHODS: We retrospectively included adults with COVID-19-ARDS requiring invasive mechanical ventilation (MV) for ≥ 48 h at any of 15 intensive care units in 2020. We divided the patients into two groups based on whether they did or did not receive corticosteroids within 24 h. The primary outcome was VAP incidence, with death and extubation as competing events. Secondary outcomes were day 90-mortality, MV duration, other organ dysfunctions, and VAP characteristics. MEASUREMENTS AND MAIN RESULTS: Of 670 patients (mean age, 65 years), 369 did and 301 did not receive early corticosteroids. The cumulative VAP incidence was higher with early corticosteroids (adjusted hazard ratio [aHR] 1.29; 95% confidence interval [95% CI] 1.05-1.58; P = 0.016). Antibiotic resistance of VAP bacteria was not different between the two groups (odds ratio 0.94, 95% CI 0.58-1.53; P = 0.81). 90-day mortality was 30.9% with and 24.3% without early corticosteroids, a nonsignificant difference after adjustment on age, SOFA score, and VAP occurrence (aHR 1.15; 95% CI 0.83-1.60; P = 0.411). VAP was associated with higher 90-day mortality (aHR 1.86; 95% CI 1.33-2.61; P = 0.0003). CONCLUSIONS: Early corticosteroid treatment was associated with VAP in patients with COVID-19-ARDS. Although VAP was associated with higher 90-day mortality, early corticosteroid treatment was not. Longitudinal randomized controlled trials of early corticosteroids in COVID-19-ARDS requiring MV are warranted.

Predictive factors for severe long-term chronic kidney disease after acute kidney injury requiring renal replacement therapy in critically ill patients: an ancillary study of the ELVIS randomized controlled trial.

BACKGROUND: Acute kidney injury (AKI) requiring renal replacement therapy (RRT) is a serious complication in the ICU that results in increased mortality and risk of chronic kidney disease (CKD). Some studies suggest RRT modality may have an impact on long-term renal recovery after AKI. However, other predictive factors of severe long-term CKD in ICU patients with AKI requiring RRT are unknown. METHODS: We performed an ancillary study of the multicenter ELVIS trial in the population with AKI requiring RRT. Patients alive 3 months after RRT initiation were eligible. Serum creatinine levels available at 3, 6 and 12 months and 3 and 5 years were recorded. CKD stage was determined according to the glomerular filtration rate as estimated by the CKD-EPI formula. At each timepoint, two groups of patients were compared, a no/mild CKD group with normal or mildly to moderately decreased renal function (stages 1, 2 and 3 of the international classification) and a severe CKD group (stages 4 and 5). Our objective was to identify predictive factors of severe long-term CKD. RESULTS: Of the 287 eligible patients, 183 had follow-up at 3 months, 136 (74.3%) from the no/mild CKD group and 47 (25.7%) from the severe CKD group, and 122 patients at 5 years comprising 96 (78.7%) from the no/mild CKD group and 26 (21.3%) from the severe CKD group. Multivariate analysis showed that a long RRT period was associated with severe CKD up to 12 months (ORM12 = 1.03 95% CI [1.02-1.05] per day) and that a high SOFA score at the initiation of RRT was not associated with severe CKD up to 5 years (ORM60 = 0.85 95% CI [0.77-0.93] per point). CONCLUSION: Severe long-term CKD was found in 21% of ICU survivors who underwent RRT for AKI. The duration of the RRT in AKI patients was identified as a new predictive factor for severe long-term CKD. This finding should be taken into consideration in future studies on the prognosis of ICU patients with AKI requiring RRT. Trial registration ELVIS trial was registered with ClinicalTrials.gov, number: NCT00875069 (June 16, 2014), and this ancillary study was registered with ClinicalTrials.gov, number: NCT03302624 (October 6, 2017).

Survival in Immunocompromised Patients Ultimately Requiring Invasive Mechanical Ventilation: A Pooled Individual Patient Data Analysis.

Rationale: Acute respiratory failure (ARF) is associated with high mortality in immunocompromised patients, particularly when invasive mechanical ventilation is needed. Therefore, noninvasive oxygenation/ventilation strategies have been developed to avoid intubation, with uncertain impact on mortality, especially when intubation is delayed. Objectives: We sought to report trends of survival over time in immunocompromised patients receiving invasive mechanical ventilation. The impact of delayed intubation after failure of noninvasive strategies was also assessed. Methods: Systematic review and meta-analysis using individual patient data of studies that focused on immunocompromised adult patients with ARF requiring invasive mechanical ventilation. Studies published in English were identified through PubMed, Web of Science, and Cochrane Central (2008-2018). Individual patient data were requested from corresponding authors for all identified studies. We used mixed-effect models to estimate the effect of delayed intubation on hospital mortality and described mortality rates over time. Measurements and Main Results: A total of 11,087 patients were included (24 studies, three controlled trials, and 21 cohorts), of whom 7,736 (74%) were intubated within 24 hours of ICU admission (early intubation). The crude mortality rate was 53.2%. Adjusted survivals improved over time (from 1995 to 2017, odds ratio [OR] for hospital mortality per year, 0.96 [0.95-0.97]). For each elapsed day between ICU admission and intubation, mortality was higher (OR, 1.38 [1.26-1.52]; P < 0.001). Early intubation was significantly associated with lower mortality (OR, 0.83 [0.72-0.96]), regardless of initial oxygenation strategy. These results persisted after propensity score analysis (matched OR associated with delayed intubation, 1.56 [1.44-1.70]). Conclusions: In immunocompromised intubated patients, survival has improved over time. Time between ICU admission and intubation is a strong predictor of mortality, suggesting a detrimental effect of late initial oxygenation failure.

Outcomes of patients admitted to the ICU for acute stroke: a retrospective cohort.

BACKGROUND: Although acute stroke is a leading cause of morbidity and mortality worldwide, data on outcomes of stroke patients requiring ICU admission are limited. We aimed to identify factors associated with a good neurological outcome (defined as a modified Rankin Scale score [mRS] of 0-2) 6 months after ICU admission. METHODS: We retrospectively studied consecutive patients who were admitted to the ICU of a French university-affiliated hospital between January 2014 and December 2018 and whose ICD-10 code indicated acute stroke. Patients with isolated subarachnoid hemorrhage or posttraumatic stroke were excluded. RESULTS: The 323 identified patients had a median age of 67 [54.5-77] years; 173 (53.6%) were male. The main reasons for ICU admission were neurological failure (87%), hemodynamic instability (28.2%), acute respiratory failure (26%), and cardiac arrest (5.3%). At ICU admission, the Glasgow Coma Scale score was 6 [4-10] and the SAPSII was 54 [35-64]. The stroke was hemorrhagic in 248 (76.8%) patients and ischemic in 75 (23.2%). Mechanical ventilation was required in 257 patients (79.6%). Six months after ICU admission, 61 (19.5%) patients had a good neurological outcome (mRS, 0-2), 50 (16%) had significant disability (mRS, 3-5), and 202 (64.5%) had died; 10 were lost to follow-up. By multivariable analysis, factors independently associated with not having an mRS of 0-2 at 6 months were older age (odds ratio, 0.93/year; 95% confidence interval, 0.89-0.96; P < 0.01) and lower Glasgow Coma Scale score at ICU admission (odds ratio, 1.23/point; 95% confidence interval, 1.07-1.40; P < 0.01). CONCLUSIONS: Acute stroke requiring ICU admission carried a poor prognosis, with less than a fifth of patients having a good neurological outcome at 6 months. Age and depth of coma independently predicted the outcome.

The hemodynamic effects of warm versus room-temperature crystalloid fluid bolus therapy in post-cardiac surgery patients.

INTRODUCTION: The contribution of fluid temperature to the effect of crystalloid fluid bolus therapy (FBT) in post-cardiac surgery patients is unknown. We evaluated the hemodynamic effects of FBT with fluid warmed to 40°C (warm FBT) versus room-temperature fluid. METHODS: In this single centre prospective before-and-after study, we evaluated the effects of 500 ml of warm versus room-temperature compound sodium lactate administered over <30 minutes, in 50 cardiac surgery patients admitted to ICU. We recorded hemodynamics continuous before and for 30 minutes after the first FBT. We defined CI responsiveness (CI-R) as an CI increase >15% of baseline immediately after FBT and effect dissipation if the CI returned to <5% of baseline and MAP responsiveness as >10% increase and dissipation as return to <3 mmHg of baseline. RESULTS: Hypotension (56%) and low CI (40%) typically triggered FBT. Temperature decreased >0.3°C in 13 (52%) patients after room-temperature FBT versus 0 (0%) after warm FBT (p < 0.01). CI and MAP responsiveness was similar (16 [64%] versus 11 [44%], p = 0.15 and 15 [60%] versus 17 [68%], p = 0.77, respectively). Among CI responders, CI increased more with room-temperature FBT (+0.6 [IQR, 0.5-1.1] versus +0.5 [IQR, 0.4-0.6] L/min/m2, p = 0.01). However, dissipation was more common after room-temperature versus warm FBT (9/16 [56%] versus 1/11 [9%], p = 0.02). CONCLUSION: In postoperative cardiac surgery patients, warm FBT preserved core temperature and induced smaller but more sustained CI increases among responders. Fluid temperature appears to impact both core temperature and the duration of CI response.

Harmonizing Heterogeneous Endpoints in Coronavirus Disease 2019 Trials Without Loss of Information.

OBJECTIVES: Many trials investigate potential effects of treatments for coronavirus disease 2019. To provide sufficient information for all involveddecision-makers (clinicians, public health authorities, and drug regulatory agencies), a multiplicity of endpoints must be considered. The objectives are to provide hands-on statistical guidelines for harmonizing heterogeneous endpoints in coronavirus disease 2019 clinical trials. DESIGN: Randomized controlled trials for patients infected with coronavirus disease 2019. SETTING: General methods that apply to any randomized controlled trial for patients infected with coronavirus disease 2019. PATIENTS: Coronavirus disease 2019 positive individuals. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We develop a multistate model that is based on hospitalization, mechanical ventilation, death, and discharge. These events are both categories of the ordinal endpoint recommended by the World Health Organization and also within the core outcome set of the Core Outcome Measures in Effectiveness Trials initiative for coronavirus disease 2019 trials. To support our choice of states in the multistate model, we also perform a brief review of registered coronavirus disease 2019 clinical trials. Based on the multistate model, we give recommendation for compact, informative illustration of time-dynamic treatment effects and explorative statistical analysis. A majority of coronavirus disease 2019 clinical trials collect information on mechanical ventilation, hospitalization, and death. Using reconstructed and real data of coronavirus disease 2019 trials, we show how a stacked probability plot provides a detailed understanding of treatment effects on the patients' course of hospital stay. It contributes to harmonizing multiple endpoints and differing lengths of follow-up both within and between trials. CONCLUSIONS: All ongoing clinical trials should include a stacked probability plot in their statistical analysis plan as descriptive analysis. While primary analysis should be on an early endpoint with appropriate capability to be a surrogate (parameter), our multistate model provides additional detailed descriptive information and links results within and between coronavirus disease 2019 trials.

Diagnostic strategy for trigger identification in severe reactive hemophagocytic lymphohistiocytosis: A diagnostic accuracy study.

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.

Comparison of the Hemodynamic and Temperature Effects of a 500-mL Bolus of 4% Albumin at Room Versus Body Temperature in Cardiac Surgery Patients.

OBJECTIVE: To compare the hemodynamic effect of room temperature (cold) 4% albumin fluid bolus therapy (FBT) with body temperature (warm) albumin FBT. DESIGN: Prospective, before-after trial. SETTING: A tertiary intensive care unit (ICU). PARTICIPANTS: Sixty ventilated, post-cardiac surgery patients prescribed with 4% albumin FBT. INTERVENTION: Cold or warm 4% albumin 500 ml FBT. MEASUREMENTS AND MAIN RESULTS: We recorded hemodynamic parameters before and for 30 minutes after FBT. Cardiac index (CI) and mean arterial pressure (MAP) responses were defined by a CI increase >15% and a MAP increase >10%, respectively. Immediately after FBT, median [interquartile range] core temperature changed by -0.3 [-0.4; -0.3] °C with cold albumin vs. 0.0 [0.0; 0.1]°C with warm albumin (P<0.001). The median CI increase was 0.3 [0.0; 0.5] L/min/m2 with 14 CI-responders (47%) in both groups (P>0.99). The median immediate MAP increase was 9 [3; 15] mmHg with cold albumin vs. 11 [5; 13] mmHg with warm albumin (P=0.79), with a MAP-response in 16 vs. 17 patients (P=0.99). There was an interaction between group and time for MAP (P=0.002), mean pulmonary artery pressure (PAP) (P=0.002) and core temperature (P<0.001). In the cold albumin group, after the initial response, MAP and mean PAP decreased more slowly than with warm albumin and, after the initial fall, core temperature increased toward baseline. CONCLUSION: In postoperative cardiac surgery patients, warm albumin FBT prevents the decrease in core temperature and, after an initial similar increase, is associated with a faster return of MAP and mean PAP toward baseline.

Point-of-care creatinine measurements to predict acute kidney injury.

BACKGROUND: Plasma creatinine (Cr) is a marker of kidney function and typically measured once daily. We hypothesized that Cr measured by point-of-care technology early after ICU admission would be a good predictor of acute kidney injury (AKI) the next day in critically ill patients. METHODS: We conducted a retrospective database audit in a single tertiary ICU database. We included patients with normal first admission Cr (CrF ) and identified a Cr value (CrP ) obtained within 6-12 hours from ICU admission. We used their difference converted into percentage (delta-Cr-%) to predict subsequent AKI (based on Cr and/or need for renal replacement therapy) the next day. We assessed predictive value by calculating area under the receiver characteristic curve (AUC), logistic regression models for AKI with and without delta-Cr-%, and the category-free net reclassifying index (cfNRI). RESULTS: We studied 780 patients. Overall, 70 (9.0%) fulfilled the Cr AKI definition by CrP measurement. On day 2, 148 patients (19.0%) were diagnosed with AKI. AUC (95% CI) for delta-Cr-% to predict AKI on day 2 was 0.82 (95% CI 0.78-0.86), and 0.74 (95% CI 0.69-0.80) when patients with AKI based on the CrP were excluded. Using a cut-off of 17% increment, the positive likelihood ratio (95% CI) for delta-Cr-% to predict AKI was 3.5 (2.9-4.2). The cfNRI was 90.0 (74.9-106.1). CONCLUSIONS: Among patients admitted with normal Cr, early changes in Cr help predict AKI the following day.

Enteral versus parenteral early nutrition in ventilated adults with shock: a randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2).

BACKGROUND: Whether the route of early feeding affects outcomes of patients with severe critical illnesses is controversial. We hypothesised that outcomes were better with early first-line enteral nutrition than with early first-line parenteral nutrition. METHODS: In this randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2 trial) done at 44 French intensive-care units (ICUs), adults (18 years or older) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned (1:1) to either parenteral nutrition or enteral nutrition, both targeting normocaloric goals (20-25 kcal/kg per day), within 24 h after intubation. Randomisation was stratified by centre using permutation blocks of variable sizes. Given that route of nutrition cannot be masked, blinding of the physicians and nurses was not feasible. Patients receiving parenteral nutrition could be switched to enteral nutrition after at least 72 h in the event of shock resolution (no vasopressor support for 24 consecutive hours and arterial lactate <2 mmol/L). The primary endpoint was mortality on day 28 after randomisation in the intention-to-treat-population. This study is registered with ClinicalTrials.gov, number NCT01802099. FINDINGS: After the second interim analysis, the independent Data Safety and Monitoring Board deemed that completing patient enrolment was unlikely to significantly change the results of the trial and recommended stopping patient recruitment. Between March 22, 2013, and June 30, 2015, 2410 patients were enrolled and randomly assigned; 1202 to the enteral group and 1208 to the parenteral group. By day 28, 443 (37%) of 1202 patients in the enteral group and 422 (35%) of 1208 patients in the parenteral group had died (absolute difference estimate 2·0%; [95% CI -1·9 to 5·8]; p=0·33). Cumulative incidence of patients with ICU-acquired infections did not differ between the enteral group (173 [14%]) and the parenteral group (194 [16%]; hazard ratio [HR] 0·89 [95% CI 0·72-1·09]; p=0·25). Compared with the parenteral group, the enteral group had higher cumulative incidences of patients with vomiting (406 [34%] vs 246 [20%]; HR 1·89 [1·62-2·20]; p<0·0001), diarrhoea (432 [36%] vs 393 [33%]; 1·20 [1·05-1·37]; p=0·009), bowel ischaemia (19 [2%] vs five [<1%]; 3·84 [1·43-10·3]; p=0·007), and acute colonic pseudo-obstruction (11 [1%] vs three [<1%]; 3·7 [1·03-13·2; p=0·04). INTERPRETATION: In critically ill adults with shock, early isocaloric enteral nutrition did not reduce mortality or the risk of secondary infections but was associated with a greater risk of digestive complications compared with early isocaloric parenteral nutrition.

Hypothermia for Neuroprotection in Convulsive Status Epilepticus.

BACKGROUND: Convulsive status epilepticus often results in permanent neurologic impairment. We evaluated the effect of induced hypothermia on neurologic outcomes in patients with convulsive status epilepticus. METHODS: In a multicenter trial, we randomly assigned 270 critically ill patients with convulsive status epilepticus who were receiving mechanical ventilation to hypothermia (32 to 34°C for 24 hours) in addition to standard care or to standard care alone; 268 patients were included in the analysis. The primary outcome was a good functional outcome at 90 days, defined as a Glasgow Outcome Scale (GOS) score of 5 (range, 1 to 5, with 1 representing death and 5 representing no or minimal neurologic deficit). The main secondary outcomes were mortality at 90 days, progression to electroencephalographically (EEG) confirmed status epilepticus, refractory status epilepticus on day 1, "super-refractory" status epilepticus (resistant to general anesthesia), and functional sequelae on day 90. RESULTS: A GOS score of 5 occurred in 67 of 138 patients (49%) in the hypothermia group and in 56 of 130 (43%) in the control group (adjusted common odds ratio, 1.22; 95% confidence interval [CI], 0.75 to 1.99; P=0.43). The rate of progression to EEG-confirmed status epilepticus on the first day was lower in the hypothermia group than in the control group (11% vs. 22%; odds ratio, 0.40; 95% CI, 0.20 to 0.79; P=0.009), but there were no significant differences between groups in the other secondary outcomes. Adverse events were more frequent in the hypothermia group than in the control group. CONCLUSIONS: In this trial, induced hypothermia added to standard care was not associated with significantly better 90-day outcomes than standard care alone in patients with convulsive status epilepticus.

Neutropenic Enterocolitis in Critically Ill Patients: Spectrum of the Disease and Risk of Invasive Fungal Disease.

OBJECTIVES: Neutropenic enterocolitis occurs in about 5.3% of patients hospitalized for hematologic malignancies receiving chemotherapy. Data from critically ill patients with neutropenic enterocolitis are scarce. Our objectives were to describe the population of patients with neutropenic enterocolitis admitted to an ICU and to investigate the risk factors of invasive fungal disease. DESIGN: A multicentric retrospective cohort study between January 2010 and August 2017. SETTING: Six French ICUs members of the Groupe de Recherche Respiratoire en Onco-Hématologie research network. PATIENTS: Adult neutropenic patients hospitalized in the ICU with a diagnosis of enteritis and/or colitis. Patients with differential diagnosis (Clostridium difficile colitis, viral colitis, inflammatory enterocolitis, mesenteric ischemia, radiation-induced gastrointestinal toxicity, and Graft vs Host Disease) were excluded. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: We included 134 patients (median Sequential Organ Failure Assessment 10 [8-12]), with 38.8% hospital mortality and 32.1% ICU mortality rates. The main underlying malignancies were acute leukemia (n = 65, 48.5%), lymphoma (n = 49, 36.6%), solid tumor (n = 14, 10.4%), and myeloma (n = 4, 3.0%). Patients were neutropenic during a median of 14 days (9-22 d). Infection was documented in 81 patients (60.4%), including an isolated bacterial infection in 64 patients (47.8%), an isolated fungal infection in nine patients (6.7%), and a coinfection with both pathogens in eight patients (5.0%). Radiologically assessed enteritis (odds ratio, 2.60; 95% CI, 1.32-7.56; p = 0.015) and HIV infection (odds ratio, 2.03; 95% CI, 1.21-3.31; p = 0.016) were independently associated with invasive fungal disease. CONCLUSIONS: The rate of invasive fungal disease reaches 20% in patients with neutropenic enterocolitis when enteritis is considered. To avoid treatment delay, antifungal therapy might be systematically discussed in ICU patients admitted for neutropenic enterocolitis with radiologically assessed enteritis.

Intensive care unit admission in patients with T cell lymphomas: clinical features and outcome.

T cell non-Hodgkin lymphomas (T-NHLs) are aggressive malignancies which have a high risk of life-threatening complications. However, their prognosis in the intensive care unit (ICU) setting has not yet been assessed. We conducted a study including 87 ICU patients either with newly diagnosed T-NHLs or those undergoing first-line therapy admitted between January 1, 2000, and December 31, 2014. The primary subtypes were peripheral T cell lymphoma (PTCL) (n = 41, 47%), anaplastic large-cell lymphoma (ALCL) (n = 13, 15%), and adult T-leukaemia/lymphoma (ATLL) (n = 11, 13%). Six in every ten patients had malignancy-related complications (haemophagocytic syndrome 37%, tumour lysis syndrome 18% and hypercalcaemia 9%), while infections accounted for one quarter of ICU admissions. Nine fungal infections were documented, including six invasive aspergillosis. Urgent chemotherapy was started in the ICU in 59% of the patients, and urgent surgery was required in 13%. ICU and day-90 mortality were 22% and 41%, respectively. Multivariate analysis showed that SOFA score at day 1, age, sepsis and haemophagocytic syndrome were independent predictors of day-90 mortality. Compared to 66 ICU-matched controls with non-Hodgkin B cell lymphomas, patients with T-NHLs had a similar ICU survival. Overall survival rates of patients with T cell NHLs and B cell NHLs were 20% and 46%, respectively (hazard ratio for death associated with T cell NHLs 2.00 [1.12-3.58]). Patients with T cell NHLs had a very poor long-term outcome. Although the high rate of short-term survival suggests that an ICU trial is a reasonable option for patients newly diagnosed for the malignancy, extended stay in the ICU or further readmission should be considered only for highly selected patients who respond to the haematological treatment.
