RESUMO

BACKGROUND: Impact of in-ICU transfusion on long-term outcomes remains unknown. The purpose of this study was to assess in critical-care survivors the association between in-ICU red blood cells transfusion and 1-year mortality. METHODS: FROG-ICU, a multicenter European study enrolling all-comers critical care patients was analyzed (n = 1551). Association between red blood cells transfusion administered in intensive care unit and 1-year mortality in critical care survivors was analyzed using an augmented inverse probability of treatment weighting-augmented inverse probability of censoring weighting method to control confounders. RESULTS: Among the 1551 ICU-survivors, 42% received at least one unit of red blood cells while in intensive care unit. Patients in the transfusion group had greater severity scores than those in the no-transfusion group. According to unweighted analysis, 1-year post-critical care mortality was greater in the transfusion group compared to the no-transfusion group (hazard ratio (HR) 1.78, 95% CI 1.45-2.16). Weighted analyses including 40 confounders, showed that transfusion remained associated with a higher risk of long-term mortality (HR 1.21, 95% CI 1.06-1.46). CONCLUSIONS: Our results suggest a high incidence of in-ICU RBC transfusion and that in-ICU transfusion is associated with a higher 1-year mortality among in-ICU survivors.

RESUMO

Rationale: Subclinical acute kidney injury (sub-AKI) refers to patients with low serum creatinine but elevated alternative biomarkers of AKI. Its incidence and outcome in critically ill patients remain, however, largely unknown. Plasma proenkephalin A 119-159 (penKid) has been proposed as a sensitive biomarker of glomerular function.Objectives: In this ancillary study of two cohorts, we explored the incidence and outcome of sub-AKI based on penKid.Methods: A prospective observational study in ICUs was conducted. FROG-ICU (French and European Outcome Registry in ICUs) enrolled 2,087 critically ill patients, and AdrenOSS-1 (Adrenomedullin and Outcome in Severe Sepsis and Septic Shock-1) enrolled 583 septic patients. The primary endpoint was 28-day mortality after ICU admission. Sub-AKI was defined by an admission penKid concentration above the normal range (i.e., >80 pmol/L) in patients not meeting the definition of AKI. A sensitivity analysis was performed among patients with estimated glomerular filtration rate above 60 ml/min/1.73 m2 at ICU admission.Measurements and Main Results: In total, 6.1% (122/2,004) and 6.7% (39/583) of patients from the FROG-ICU and AdrenOSS-1 cohorts met the definition of sub-AKI (11.6% and 17.5% of patients without AKI). In patients without AKI or with high estimated glomerular filtration rate, penKid was associated with higher mortality (adjusted standardized hazard ratio [HR], 1.4 [95% confidence interval, 1.1-1.8]; P = 0.010; and HR, 1.6 [95% confidence interval, 1.3-1.8]; P < 0.0001, respectively) after adjustment for age, sex, comorbidities, diagnosis, creatinine, diuresis, and study. Patients with sub-AKI had higher mortality compared with no AKI (HR, 2.4 [95% confidence interval, 1.5-3.7] in FROG-ICU and 2.5 [95% confidence interval, 1.1-5.9] in AdrenOSS-1).Conclusions: Sub-AKI defined using penKid occurred in 11.6-17.5% of patients without AKI and was associated with a risk of death close to patients with AKI.

RESUMO

OBJECTIVES: Adrenomedullin has vascular properties and elevated plasma adrenomedullin levels were detected in sepsis. We assessed, in septic and nonseptic ICU patients, the relation between circulating adrenomedullin, the need for organ support and mortality, using an assay of bioactive adrenomedullin. DESIGN: Prospective multicenter observational cohort study. SETTING: Data from the French and euRopean Outcome reGistry in ICUs study. PATIENTS: Consecutive patients admitted to intensive care with a requirement for invasive mechanical ventilation and/or vasoactive drug support for more than 24 hours following ICU admission and discharged from ICU were included. INTERVENTIONS: Clinical and biological parameters were collected at baseline, including bioactive-adrenomedullin. Status of ICU survivors was assess until 1 year after discharge. The main outcome was the need for organ support, including renal replacement therapy and/or for inotrope(s) and/or vasopressor(s). Secondary endpoints were the ICU length of stay and the 28-day all-cause mortality. MEASUREMENTS AND MAIN RESULTS: Median plasma bioactive adrenomedullin (n = 2,003) was 66.6 pg/mL (34.6-136.4 pg/mL) and the median Simplified Acute Physiology Score II score 49 (36-63). Renal replacement therapy was needed in 23% and inotropes(s) and/or vasopressor(s) in 77% of studied patients. ICU length of stay was 13 days (7-21 d) and mortality at 28 days was 22 %. Elevated bioactive adrenomedullin independently predicted 1) the need for organ support (odds ratio, 4.02; 95% CI, 3.08-5.25) in ICU patients whether admitted for septic or nonseptic causes and 2) the need for renal replacement therapy (odds ratio, 4.89; 3.83-6.28), and for inotrope(s) and/or vasopressor(s) (odds ratio, 3.64; 2.84-4.69), even in patients who were not on those supports at baseline. Elevated bioactive adrenomedullin was also associated with a prolonged length of stay (odds ratio, 1.85; 1.49-2.29) and, after adjustment for Simplified Acute Physiology Score II, with mortality (odds ratio, 2.31; 1.83-2.92). CONCLUSIONS: Early measurement of bioactive adrenomedullin is a strong predictor of the need of organ support and of short-term mortality in critically ill patients.

RESUMO

RATIONALE: The urinary proteome reflects molecular drivers of disease. OBJECTIVES: To construct a urinary proteomic biomarker predicting 1-year post-ICU mortality. METHODS: In 1243 patients, the urinary proteome was measured on ICU admission, using capillary electrophoresis coupled with mass spectrometry along with clinical variables, circulating biomarkers (BNP, hsTnT, active ADM, and NGAL), and urinary albumin. Methods included support vector modeling to construct the classifier, Cox regression, the integrated discrimination (IDI), and net reclassification (NRI) improvement, and area under the curve (AUC) to assess predictive accuracy, and Proteasix and protein-proteome interactome analyses. MEASUREMENTS AND MAIN RESULTS: In the discovery (deaths/survivors, 70/299) and test (175/699) datasets, the new classifier ACM128, mainly consisting of collagen fragments, yielding AUCs of 0.755 (95% CI, 0.708-0.798) and 0.688 (0.656-0.719), respectively. While accounting for study site and clinical risk factors, hazard ratios in 1243 patients were 2.41 (2.00-2.91) for ACM128 (+ 1 SD), 1.24 (1.16-1.32) for the Charlson Comorbidity Index (+ 1 point), and ≥ 1.19 (P ≤ 0.022) for other biomarkers (+ 1 SD). ACM128 improved (P ≤ 0.0001) IDI (≥ + 0.50), NRI (≥ + 53.7), and AUC (≥ + 0.037) over and beyond clinical risk indicators and other biomarkers. Interactome mapping, using parental proteins derived from sequenced peptides included in ACM128 and in silico predicted proteases, including/excluding urinary collagen fragments (63/35 peptides), revealed as top molecular pathways protein digestion and absorption, lysosomal activity, and apoptosis. CONCLUSIONS: The urinary proteomic classifier ACM128 predicts the 1-year post-ICU mortality over and beyond clinical risk factors and other biomarkers and revealed molecular pathways potentially contributing to a fatal outcome.

RESUMO

OBJECTIVES: The association between outcome and kidney injury detected at discharge from the ICU using different biomarkers remains unknown. The objective was to evaluate the association between 1-year survival and kidney injury at ICU discharge. DESIGN: Ancillary investigation of a prospective observational study. SETTING: Twenty-one ICUs with 1-year follow-up. PATIENTS: Critically ill patients receiving mechanical ventilation and/or hemodynamic support for at least 24 hours were included. INTERVENTIONS: Serum creatinine, plasma Cystatin C, plasma neutrophil gelatinase-associated lipocalin, urinary neutrophil gelatinase-associated lipocalin, plasma Proenkephalin A 119-159, and estimated glomerular filtration rate (on serum creatinine and plasma Cystatin C) were measured at ICU discharge among ICU survivors. MEASUREMENTS AND MAIN RESULTS: The association between kidney biomarkers at discharge and mortality was estimated using logistic model with and without adjustment for prognostic factors previously identified in this cohort. Subgroup analyses were performed in patients with discharge serum creatinine less than 1.5-fold baseline at ICU discharge. Among 1,207 ICU survivors included, 231 died during the year following ICU discharge (19.2%). Estimated glomerular filtration rate was significantly lower and kidney injury biomarkers higher at discharge in nonsurvivors. The association between biomarker levels or estimated glomerular filtration rate and mortality remained after adjustment to potential cofounding factors influencing outcome. In patients with low serum creatinine at ICU discharge, 25-47% of patients were classified as subclinical kidney injury depending on the biomarker. The association between kidney biomarkers and mortality remained and mortality was higher than patients without subclinical kidney injury. The majority of patients who developed acute kidney injury during ICU stay had elevated biomarkers of kidney injury at discharge even with apparent recovery based on serum creatinine (i.e., subclinical acute kidney disease). CONCLUSIONS: Elevated kidney biomarkers measured at ICU discharge are associated with poor 1-year outcome, including in patients with low serum creatinine at ICU discharge.

RESUMO

PURPOSE: This study aimed to investigate the association between the use of early echocardiography performed by the treating physician certified in critical care ultrasound and mortality in ICU patients. MATERIALS AND METHODS: FROG-ICU was a multi-center cohort designed to investigate the outcome of critically ill patients. Of the 1359 patients admitted to centers where echocardiography was available, 372 patients underwent echocardiography during the initial 3 days. RESULTS: Of the ICU patients admitted for cardiac disease, 47.4% underwent echocardiography, and those patients had the lowest left ventricular ejection fraction 40 [31-58] % and the lowest cardiac output 4.2 [3.2-5.7] L/min compared to patients admitted for other causes (p < 0.001 for both). One-year mortality was 36.8% and 39.9% in patients with and without echocardiography, respectively [HR 0.92 (95% CI 0.75-1.11)]. This result was confirmed after multivariable Cox regression analysis [HR 0.88 (95% CI 0.71-1.08)]. Subgroup analyses suggest that among patients admitted to ICU for cardiac disease, those managed with echocardiography had a lower risk of one-year mortality [HR 0.65 (95% CI 0.43-0.98)]. CONCLUSIONS: Early echocardiography by treating physicians was not associated with short- or long-term survival in ICU patients. In subgroups, early echocardiography improved survival in ICU patients admitted for cardiac disease. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01367093.

RESUMO

PURPOSE: Few studies analyzed gender-related outcome differences of critically ill patients and found inconsistent results. This study aimed to test the independent association of gender and long-term survival of ICU patients. MATERIALS AND METHODS: FROG-ICU was a prospective, observational, multi-center cohort designed to investigate the long-term mortality of critically ill adult patients. The primary endpoint of this study was 1-year mortality after ICU admission of women compared to men. RESULTS: The study included 2087 patients, 726 women and 1361 men. Women and men had similar baseline characteristics, clinical presentation, and disease severity. No significant difference in 1-year mortality was found between women and men (34.9% vs. 37.9%, P = 0.18). After multivariable adjustment, no difference in the hazard of death was observed [HR 0.99 (95% CI 0.77-1.28)]. Similar 1-year survival between women and men was found in a propensity score-matched patient cohort of 506 patients [HR 0.79 (95% CI 0.54-1.14)]. CONCLUSION: Women constituted one-third of the population of critically ill patients and were unexpectedly similar to men regarding demographic characteristics, clinical presentation, and disease severity and had similar risk of death at 1 year after ICU admission.

RESUMO

PURPOSE: Intensive care unit survivors suffer from prolonged impairment, reduced quality of life, and higher mortality rates after discharge compared to the general population. Socioeconomic status may play a partial but important role in mortality and recovery. Therefore, the detection of factors that are responsible for poor long-term outcomes would be beneficial in designing targeted interventions for at-risk populations. METHODS: For an endpoint analysis, 1834 intensive care unit patients with known French Deprivation Index (FDep) scores were included from the French and euRopean Outcome reGistry in Intensive Care Units (FROG-ICU) study, which was a prospective, observational, multicenter cohort study performed in 20 French intensive care units in 13 different hospitals. Socioeconomic status was defined by using the FDep score [represented as quintiles when referring to the general French population, as quintiles when referring to the FROG-ICU cohort, or as dichotomized data (which was defined as a FDep ≤ 0 for nondeprived patients)] and by using a detailed social questionnaire that was completed 3 months after discharge. The primary outcome included an all-cause, 1-year mortality after ICU discharge when regarding socioeconomic status. The secondary outcomes included both ICU and hospital lengths of stay, both short- and medium-term mortality, and the quality of life, as assessed during the 1-year follow-up by using the Medical Outcome Survey Short Form-36 (SF-36). The Revised Impact of Event Scale (IES-R) was used to evaluate the symptoms of post-traumatic stress disorder, and the Hospital Anxiety and Depression Scale (HADS) was used to screen for anxiety and depression. RESULTS: Of the 1447 patients who were discharged alive from the ICU, 19.2% died over the following year. No association was found between 1-year mortality and socioeconomic status, regardless of whether this association was analyzed in quintiles (p = 0.911 in the quintiles of the general French population; p = 0.589 in the quintiles of the FROG-ICU cohort itself) or as dichotomized data [nondeprived (n = 177; 1-year mortality of 18.2%) versus deprived (n = 97; 1-year mortality of 20.5%; p = 0.304)]. Moreover, no differences were found between the nondeprived and the deprived patients in the ICU and hospital lengths of stay, ICU mortalities, in-hospital mortalities, or 28-day mortalities. The SF-36 was below the score for the normal French population throughout the follow-up period. Socially deprived patients showed significantly lower median scores in the physical function subscale [55, interquartile range (IQR) (28.8-80) vs. 65, IQR (35-90); p = 0.014], the physical role subscale [25, IQR (0-75) vs. 33.3, IQR (0-100); p = 0.022], and the overall physical component scale [47.5, IQR (30-68.8) vs. 54.4, IQR (35-78.8); p = 0.010]. Up to 31.6% of survivors presented symptoms that indicated post-traumatic stress disorder, and up to 31.5% of survivors reported clinically meaningful symptoms of anxiety or depression. CONCLUSIONS: A lower socioeconomic status was associated with lower self-reported physical component scores in the nondeprived patients. Psychiatric symptoms are frequently reported after an ICU stay, and subsequent interventions should target those fields.

RESUMO

PURPOSE: Acute kidney injury (AKI) is associated with the activation of the renin-angiotensin system. Whether angiotensin-converting enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARB) improve outcome in patients recovering from AKI remains unexplored. The purpose was to investigate the association between prescription of ACEi/ARB at intensive care unit (ICU) discharge and 1-year outcome in patients recovering from AKI. METHODS: Association between ACEi/ARB and 1-year mortality rate was explored in 1551 patients discharged from 21 European ICUs in an observational cohort. One-year all-cause mortality after ICU discharge was the primary endpoint. AKI was defined using the kidney disease improvement global outcome definition. Propensity score matching was used to consider the probability to receive ACEi/ARB at ICU discharge and included chronic heart failure, ACEi/ARB on ICU admission, Charlson Comorbidity Index, age, diabetes mellitus, chronic kidney disease, estimated glomerular filtration rate and arterial blood pressure at ICU discharge vasopressors and renal replacement therapy. RESULTS: Overall, 1-year mortality was 28 and 15% in patients with AKI (n = 611, 39%) and without AKI (n = 940), respectively. In patients with AKI, unadjusted, adjusted and propensity-score matched 1-year mortality rates were lower in patients treated with ACEi/ARB at ICU discharge [HR of 0.55 (0.35-0.89), HR of 0.45 (0.27-0.75), and HR of 0.48 (0.27-0.85, p < 0.001), respectively]. These results were consistent across sensitivity analysis. No association was observed in patients without AKI. CONCLUSIONS: In patients discharged alive from the ICU after experiencing AKI, ACEi/ARB prescription at discharge is associated with a decrease in 1-year mortality.
