RESUMEN
BACKGROUND: Due to aging population and increasing part of immunocompromised patients, a raise in life-threatening organ damage related to VZV can be expected. Two retrospective studies were already conducted on VZV in ICU but focused on specific organ injury. Patients with high-risk of VZV disease still must be identified. The objective of this study was to report the clinical features and outcome of all life-threatening VZV manifestations requiring intensive care unit (ICU) admission. This retrospective cohort study was conducted in 26 French ICUs and included all adult patients with any life-threatening VZV-related event requiring ICU admission or occurring in ICU between 2010 and 2019. RESULTS: One-hundred nineteen patients were included with a median SOFA score of 6. One hundred eight patients (90.8%) were admitted in ICU for VZV disease, leaving 11 (9.2%) with VZV disease occurring in ICU. Sixty-one patients (51.3%) were immunocompromised. Encephalitis was the most prominent organ involvement (55.5%), followed by pneumonia (44.5%) and hepatitis (9.2%). Fifty-four patients (45.4%) received norepinephrine, 72 (60.5% of the total cohort) needed invasive mechanical ventilation, and 31 (26.3%) received renal-replacement therapy. In-hospital mortality was 36.1% and was significantly associated with three independent risk factors by multivariable logistic regression: immunosuppression, VZV disease occurring in ICU and alcohol abuse. Hierarchical clustering on principal components revealed five phenotypically distinct clusters of patients: VZV-related pneumonia, mild encephalitis, severe encephalitis in solid organ transplant recipients, encephalitis in other immunocompromised hosts and VZV disease occurring in ICU. In-hospital mortality was highly different across phenotypes, ranging from zero to 75% (p < 0.001). CONCLUSION: Overall, severe VZV manifestations are associated with high mortality in the ICU, which appears to be driven by immunosuppression status rather than any specific organ involvement. Deciphering the clinical phenotypes may help clinicians identify high-risk patients and assess prognosis.
RESUMEN
The association between antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis and hematologic malignancy has been previously described and remains a rare phenomenon (although potentially underdiagnosed). We report the case of an 81-year-old patient with myelodysplastic syndrome who was managed for an infectious-appearing pneumonia, which subsequently complicated into complete heart block and severe acute respiratory distress syndrome with a fatal outcome. The final diagnosis is severe hemorrhagic alveolitis due to ANCA-associated vasculitis meeting the criteria for microscopic polyangiitis. This article provides an opportunity to discuss the association between ANCA-associated vasculitis and hematologic malignancies and the adverse prognosis associated with it.
RESUMEN
BACKGROUND: Almitrine, a selective pulmonary vasoconstrictor in hypoxic area, improves oxygenation in mechanically ventilated patients with COVID-19 but its effects in spontaneously breathing patients with COVID-19 remain to be determined. METHODS: We prospectively studied the effects of almitrine (16 µg/kg/min over 30 min followed by continuous administration in responders only) in 62 patients (66% of male, 63 [53-69] years old) with COVID-19 treated with high-flow nasal cannula oxygen therapy (HFNO) and with persistent hypoxemia, defined as a PaO2/FiO2 ratio < 100 with FiO2 > 80% after a single awake prone positioning session. Patients with an increase in PaO2/FiO2 ratio > 20% were considered as responders. RESULTS: Overall, almitrine increased the PaO2/FiO2 ratio by 50% (p < 0.01), decreased the partial arterial pressure of carbon dioxide by 7% (p = 0.01) whereas the respiratory rate remained unchanged and 46 (74%) patients were responders. No patient experienced right ventricular dysfunction or acute cor pulmonale. The proportion of responders was similar regardless of the CT-Scan radiological pattern: 71% for the pattern with predominant ground-glass opacities and 76% for the pattern with predominant consolidations (p = 0.65). Responders had lower intubation rate (33 vs. 88%, p < 0.01), higher ventilator-free days at 28-day (28 [20-28 ] vs. 19 [2-24] days, p < 0.01) and shorter ICU length of stay (5 [3-10] vs.12 [7-30] days, p < 0.01) than non-responders. CONCLUSIONS: Almitrine could be an interesting therapy in spontaneously breathing patients with COVID-19 treated with HFNO and with persistent hypoxemia, given its effects on oxygenation without serious adverse effects regardless of the CT-Scan pattern, and potentially on intubation rate. These preliminary results need to be confirmed by further randomized studies.

BACKGROUND: Trials and study-level meta-analyses have failed to resolve the role of corticosteroids in the management of patients with septic shock. Patient-level meta-analyses may provide more precise estimates of treatment effects, particularly subgroup effects. METHODS: We pooled individual patient data from septic shock trials investigating the adjunctive use of intravenous hydrocortisone. The primary outcome was 90-day all-cause mortality, and it was also analyzed across predefined subgroups. Secondary outcomes included mortality at intensive care unit and hospital discharge, at 28 and 180 days, and vasopressor-, ventilator-, and organ failurefree days. Adverse events included superinfection, muscle weakness, hyperglycemia, hypernatremia, and gastroduodenal bleeding. RESULTS: Of 24 eligible trials (n=8528), 17 (n=7882) provided individual patient data, and 7 (n=5929) provided 90-day mortality. The marginal relative risk (RR) for 90-day mortality of hydrocortisone versus placebo was 0.93 (95% confidence interval [CI], 0.82 to 1.04; P=0.22; moderate certainty). It was 0.86 (95% CI, 0.79 to 0.92) for hydrocortisone with fludrocortisone and 0.96 (95% CI, 0.82 to 1.12) without fludrocortisone. There was no significant differential treatment effect across subgroups. Hydrocortisone was associated with little to no difference in any of the secondary outcomes except vasopressor-free days (mean difference, 1.24 days; 95% CI, 0.74 to 1.73; high certainty). Hydrocortisone may not be associated with an increase in the risk of superinfection (RR, 1.04; 95% CI, 0.95 to 1.15; low certainty), hyperglycemia (RR, 1.05; 95% CI, 0.98 to 1.12; low certainty), or gastroduodenal bleeding (RR, 1.11; 95% CI, 0.83 to 1.48; low certainty). Hydrocortisone may be associated with an increase in the risk of hypernatremia (RR, 2.01; 95% CI, 1.56 to 2.60; low certainty) and muscle weakness (n=2647; RR, 1.73; 95% CI, 1.49 to 1.99; low certainty). CONCLUSIONS: In this patient-level meta-analysis, hydrocortisone compared with placebo was not associated with reduced mortality for patients with septic shock.

Background: High incidence of ventilator associated pneumonia (VAP) has been reported in critically ill patients with COVID-19. Among these patients, we aimed to assess the incidence, outcomes and risk factors of VAP recurrences. Methods: We conducted an observational retrospective study in three French intensive care units (ICUs). Patients admitted for a documented COVID-19 from March 2020 to May 2021 and requiring mechanical ventilation (MV) for ≥48 h were included. The study main outcome was the incidence of VAP recurrences. Secondary outcomes were the duration of MV, ICU and hospital length of stay and mortality according to VAP and recurrences. We also assessed the factors associated with VAP recurrences. Results: During the study period, 398 patients met the inclusion criteria. A total of 236 (59%) of them had at least one VAP episode during their ICU stay and 109 (46%) of these patients developed at least one recurrence. The incidence of VAP recurrence considering death and extubation as competing events was 29.6% (IC = [0.250−0.343]). Seventy-eight percent of recurrences were due to the same bacteria (relapses). Patients with a VAP recurrence had a longer duration of MV as compared with one VAP and no VAP patients (41 (25−56) vs. 16 (8−30) and 10 (5−18) days; p < 0.001) and a longer ICU length of stay (46 (29−66) vs. 22 (12−36) and 14 (9−25) days; p < 0.001). The 90-day mortality was higher in the recurrence group as compared with the no VAP group only (31.2 vs. 21.0% (p = 0.021)). In a multivariate analysis including bacterial co-infection at admission, the use of immunosuppressive therapies and the bacteria responsible for the first VAP episode, the duration of MV was the only factor independently associated with VAP recurrence. Conclusion: In COVID-19 associated respiratory failure, recurrences affected 46% of patients with a first episode of VAP. VAP recurrences were mainly relapses and were associated with a prolonged duration of MV and ICU length of stay but not with a higher mortality. MV duration was the only factor associated with recurrences.
RESUMEN
BACKGROUND: Stress hyperglycemia can persist during an intensive care unit (ICU) stay and result in prolonged requirement for insulin (PRI). The impact of PRI on ICU patient outcomes is not known. We evaluated the relationship between PRI and Day 90 mortality in ICU patients without previous diabetic treatments. METHODS: This is a post hoc analysis of the CONTROLING trial, involving 12 French ICUs. Patients in the personalized glucose control arm with an ICU length of stay ≥ 5 days and who had never previously received diabetic treatments (oral drugs or insulin) were included. Personalized blood glucose targets were estimated on their preadmission usual glycemia as estimated by their glycated A1c hemoglobin (HbA1C). PRI was defined by insulin requirement. The relationship between PRI on Day 5 and 90-day mortality was assessed by Cox survival models with inverse probability of treatment weighting (IPTW). Glycemic control was defined as at least one blood glucose value below the blood glucose target value on Day 5. RESULTS: A total of 476 patients were included, of whom 62.4% were male, with a median age of 66 (54-76) years. Median values for SAPS II and HbA1C were 50 (37.5-64) and 5.7 (5.4-6.1)%, respectively. PRI was observed in 364/476 (72.5%) patients on Day 5. 90-day mortality was 23.1% in the whole cohort, 25.3% in the PRI group and 16.1% in the non-PRI group (p < 0.01). IPTW analysis showed that PRI on Day 5 was not associated with Day 90 mortality (IPTWHR = 1.22; CI 95% 0.84-1.75; p = 0.29), whereas PRI without glycemic control was associated with an increased risk of death at Day 90 (IPTWHR = 3.34; CI 95% 1.26-8.83; p < 0.01). CONCLUSION: In ICU patients without previous diabetic treatments, only PRI without glycemic control on Day 5 was associated with an increased risk of death. Additional studies are required to determine the factors contributing to these results.

Background: The optimal isolation time of COVID-19 patients in intensive care unit (ICU) is debated. We investigated the impact of two different COVID-19 patient isolation time strategies on healthcare workers (HCW) contamination, intensity of nursing care and potential associated adverse events. Methods: We prospectively included all consecutive COVID-19 patients and HCW in our ICU in the first two pandemic waves (March to May 2020 and August to November 2020). Specific isolation measures for COVID-19 patients were released after two negative RT-PCR assays in the first wave and 14 days after the onset of symptoms in the second wave. Contamination of HCW was assessed at the end of each pandemic wave by combining both a RT-PCR assay and a serological test. Results: Overall, 117 COVID-19 patients and 73 HCW were included. Despite an earlier release from isolation after ICU admission in the second than in the first wave [6 (4-8) vs. 15 (11-19) days, p < 0.01], the proportion of HCW with a positive serological test (16 vs. 17%, p = 0.94) or with a positive RT-PCR assay (3 vs. 5%, p = 0.58) was not different between the two waves. Although a lower nurse-to-bed ratio, the intensity of nursing care was higher in the second than in the first wave. A longer isolation time was associated with accidental extubation (OR = 1.18, 95%CI:1.07-1.35, p = 0.005) but neither with ventilator-associated pneumonia nor with dysglycemia. Conclusion: A shorter isolation time of COVID-19 patients in ICU was not associated with higher HCW contamination, while a longer isolation time seemed to be associated with higher accidental extubation.
RESUMEN
BACKGROUND: Cardiac injury has been reported in up to 30% of coronavirus disease 2019 (COVID-19) patients. However, cardiac injury is defined mainly by troponin elevation without description of associated structural abnormalities and its time course has not been studied. RESEARCH QUESTION: What are the ECG and echocardiographic abnormalities as well as their time course in critically ill COVID-19 patients? STUDY DESIGN AND METHODS: The cardiac function of 43 consecutive COVID-19 patients admitted to two ICUs was assessed prospectively and repeatedly, combining ECG, cardiac biomarker, and transthoracic echocardiographic analyses from ICU admission to ICU discharge or death or to a maximum follow-up of 14 days. Cardiac injury was defined by troponin elevation and newly diagnosed ECG or echocardiographic abnormalities, or both. RESULTS: At baseline, 49% of patients demonstrated a cardiac injury, and 70% of patients experienced cardiac injury within the first 14 days of ICU stay, with a median time of occurrence of 3 days (range, 0-7 days). The most frequent abnormalities were ECG or echocardiographic signs, or both, of left ventricular (LV) abnormalities (87% of patients with cardiac injury), right ventricular (RV) systolic dysfunction (47%), pericardial effusion (43%), new-onset atrial arrhythmias (33%), LV relaxation impairment (33%), and LV systolic dysfunction (13%). Between baseline and day 14, the incidence of pericardial effusion and of new-onset atrial arrhythmias increased and the incidence of ECG or echocardiographic signs, or both, of LV abnormalities as well as the incidence of LV relaxation impairment remained stable, whereas the incidence of RV and LV systolic dysfunction decreased. INTERPRETATION: Cardiac injury is common and early in critically ill COVID-19 patients. ECG or echocardiographic signs, or both, of LV abnormalities were the most frequent abnormalities, and patients with cardiac injury experienced more RV than LV systolic dysfunction.

BACKGROUND: Most diseases encountered in the intensive care unit are associated with major stress that can potentially trigger Takotsubo syndrome. Many severe cardiovascular complications are associated with Takotsubo syndrome, yet little is known about Takotsubo syndrome in the intensive care unit. AIMS: We sought to determine the incidence of Takotsubo syndrome, and to describe its clinical features and outcome in an intensive care unit. METHODS: This prospective single-centre study included all patients admitted consecutively over a 12-month period who had transthoracic echocardiography, electrocardiography and a troponin I assay performed on admission, at 24 and 48hours after admission, and at discharge and in the case of clinical worsening. RESULTS: The incidence of Takotsubo syndrome was 4.6% (13/280 patients) and female sex predominated (69.2%). The median age of the subgroup with Takotsubo syndrome was 64 (56-72) years. Pulmonary disease and sepsis were the most frequent triggers (46.2% and 38.5%, respectively). Median left ventricular ejection fraction was 29.0% (20.0-37.0). Patients with Takotsubo syndrome presented with shock and arrhythmias and needed ventilation more frequently than patients without Takotsubo syndrome (69.2% vs. 36.3%, P=0.035; 46.2% vs. 13.5%, P=0.006; and 92.3% vs. 60.7%, P=0.021), but mortality rates were similar. The median delay to cardiac index recovery, when impaired, was 2.0 (1.0-2.75) days, and that of left ventricular ejection fraction was 12.5 (7-14.75) days. CONCLUSION: Takotsubo syndrome in the intensive care unit is not uncommon and is associated with substantial haemodynamic and respiratory instability. New-onset arrhythmias and respiratory and haemodynamic worsening could arouse suspicion of and prompt screening for Takotsubo syndrome in the intensive care unit.

AIMS OF THE STUDY: Most interventional and observational studies include cardiac arrest from cardiac origin. However, an increasing proportion of cardiac arrest results from an extra-cardiac origin, mainly respiratory. The aim of our study was to compare the characteristics and outcome of cardiac arrest patients according to the presumed cardiac or respiratory causes. METHODS: This retrospective multicenter observational study included out-of-hospital cardiac arrest patients from presumed cardiac and respiratory origin treated with therapeutic hypothermia. Demographic data (age, sex, initial rhythm as shockable or non-shockable, durations of no-flow and low-flow), clinical evolution in ICU, lactate and outcome (CPC scale at ICU discharge) were compared between patients according to the presumed cardiac or respiratory origin of the cardiac arrest. RESULTS: Two hundred and fifty-one cardiac arrest patients were included, 156 from presumed cardiac origin (62%) and 95 from presumed respiratory origin (38%). Patients with presumed cardiac cause presented more frequently a shockable rhythm (68% vs. 5%, pâ¯<â¯0.001), received more defibrillations attempts (2 [1-5] vs. 0 [0-0], <0.001) and needed less adrenaline (3â¯mg [0-5] vs. 4â¯mg [2-7], pâ¯=â¯0.01). The arterial lactate concentration on admission was higher in patients with presumed respiratory causes (6.3â¯mmol/L [4.2-9.8] vs. 3.2â¯mmol/L [1.6-5.0], pâ¯<â¯0.001). The proportion of patients presenting a favorable outcome was higher in the population with presumed cardiac causes, compared to its respiratory counterpart (42% vs. 19%, pâ¯<â¯0.001). CONCLUSIONS: Compared to presumed cardiac origin, a worse outcome and a different mode of death are associated with the presumed respiratory origin, resulting from a greater insult preceding cardiac arrest. The presumed cause of cardiac arrest could be integrated in the multimodal prognostication process.

We recently published a comparison of two hydrocortisone dosage regimens in patients with septic shock. We compare the results conferred by the two regimens as a function of the response to cosyntropin stimulation test (CST). Patients with septic shock were treated by one of two hydrocortisone regimens: either a 50-mg intravenous bolus every 6 h during 7 days (200âmg group; nâ=â49), or a 100-mg initial bolus followed by a continuous infusion of 300âmg daily for 5 days (300âmg group; nâ=â50). Nonresponders was defined as a CST response of 9âµg/dL or less. Nonresponders had more severe septic shock, greater fluid resuscitation needs, and greater vasopressor dependence than responders. When analyzed only as a function of CST results, there was no difference in survival between responders and nonresponders. However, analyses crossing CST results and the treatment regimens showed that patients who were responders and in the 300âmg group had significantly less intensive care unit mortality compared with responders in the 200âmg group (respective mortality of 24% vs. 55% [relative risk 0.43, 95% confidence interval, 0.20 to 0.94, Pâ=â0.018]). Multivariate analysis identified baseline blood cortisol as an independent prognostic factor for 28-day mortality in all groups (hazard ratio 1.002, 95% confidence interval, 1.001 to 1.002, Pâ≤â0.0001). The results suggest that in patients who respond to CST, hydrocortisone can provide a dose-dependent benefit. In contrast, nonresponse may indicate corticosteroid resistance. This heterogeneity of response to hydrocortisone may explain the difficulties encountered when trying to demonstrate its benefit in septic shock.

AIMS: Lactate reflects hypoxic insult in many conditions and is considered as a prognosis factor. But, after cardiac arrest, its interest is still debated. Our study aimed to assess the prognosis value of lactate in out-of-hospital cardiac arrest patients treated with therapeutic hypothermia. METHODS: This retrospective observational study included out-of-hospital cardiac arrest patients treated with therapeutic hypothermia in four ICUs. Lactate levels were compared at different times during the first 24 hours according to outcome at ICU discharge and to the type of death (multiorgan or neurologic failure). RESULTS: Two hundred and seventy-two patients were included, 89 good outcome and 183 poor outcome. In the latter group, 171 patients died, from multiorgan failure in 30% and neurologic failure in 70%. Lactate levels were higher in the poor compared to the good outcome patients at admission (5.4 (3.3-9.4) vs. 2.2 (1.5-3.6) mmol/L; p<0.01), 12 hours (2.5 (1.6-4.7) vs. 1.4 (1.0-2.2) mmol/L; p<0.01) and 24 hours (1.8 (1.1-2.8) vs. 1.3 (0.9-2.1) mmol/L; p<0.01). Patients succumbing from multiorgan failure exhibited higher lactate levels compared to those dying from neurologic failure at admission (7.9 (3.9-12.0) vs. 5.2 (3.3-8.8) mmol/L; p<0.01), H12 (4.9 (2.1-8.9) vs. 2.2 (1.4-3.4) mmol/L; p<0.01) and H24 (3.3 (1.8-5.5) vs. 1.4 (1.1-2.5) mmol/L; p<0.01). Initial lactate levels showed an increasing proportion of poor outcome from the first to fourth quartile. CONCLUSIONS: After out-of-hospital cardiac arrest treated with therapeutic hypothermia, lactate levels during the first 24 hours seem linked with ICU outcome. Patients dying from multiorgan failure exhibit higher initial lactate concentrations than patients succumbing from neurological failure.

BACKGROUND: Different modes of death are described in selected populations, but few data report the characteristics of death in a general intensive care unit population. This study analyzed the causes and characteristics of death of critically ill patients and compared anticipated death patients to unexpected death counterparts. METHODS: An observational multicenter cohort study was performed in 96 intensive care units. During 1 yr, each intensive care unit was randomized to participate during a 1-month period. Demographic data, characteristics of organ failures (Sequential Organ Failure Assessment subscore greater than or equal to 3), and organ supports were collected on all patients who died in the intensive care unit. Modes of death were defined as anticipated (after withdrawal or withholding of treatment or brain death) or unexpected (despite engagement of full-level care or sudden refractory cardiac arrest). RESULTS: A total of 698 patients were included during the study period. At the time of death, 84% had one or more organ failures (mainly hemodynamic) and 89% required at least one organ support (mainly mechanical ventilation). Deaths were considered unexpected and anticipated in 225 and 473 cases, respectively. Compared to its anticipated counterpart, unexpected death occurred earlier (1 day vs. 5 days; P< 0.001) and had fewer organ failures (1 [1 to 2] vs. 1 [1 to 3]; P< 0.01) and more organ supports (2 [2 to 3] vs. 1 [1 to 2]; P< 0.01). Withdrawal or withholding of treatments accounted for half of the deaths. CONCLUSIONS: In a general intensive care unit population, the majority of patients present with at least one organ failure at the time of death. Anticipated and unexpected deaths represent two different modes of dying and exhibit profiles reflecting the different pathophysiologic underlying mechanisms.

PURPOSE: The Surviving Sepsis Campaign guidelines recommend hydrocortisone in septic shock only when fluid resuscitation and vasopressors fail to restore hemodynamic stability. Hydrocortisone administration modalities are supported only by low-grade recommendations. Our main objective here was to determine differences in 28-day mortality between two low-dose hydrocortisone regimens for the treatment of septic shock. METHODS: We performed a multicenter, prospective, randomized, double-blind, pilot study in four adult medical intensive care units. Patients presenting septic shock were rapidly administered one of two regimens of hydrocortisone, either a 50-mg intravenous bolus every 6 h during 7 days (200-mg group; n = 59) or a 100-mg initial bolus followed by a continuous infusion of 300âmg daily for 5 days (300-mg group; n = 63). Hydrocortisone was stopped abruptly at the end of treatment. RESULTS: There were no significant differences between the 200-mg and 300-mg groups as concerns 28-day mortality (respectively 52.5% vs. 44.4% [RR 0.84, 95% CI, 0.58-1.22, Pâ=â0.47]), refractory shock incidence or delay from shock to vasopressor cessation. There were also no differences in adverse events between the groups. Shock relapse after hydrocortisone cessation was independent of hydrocortisone regimens, but it was associated with the persistence of infection and the use of etomidate. The resumption of hydrocortisone due to shock relapse was significantly more frequent in the 300-mg group. CONCLUSION: We found no differences in mortality or adverse events between the two hydrocortisone administration regimens. Shock relapse was significantly associated with the persistence of infection and the use of etomidate.

Diffuse alveolar haemorrhage (DAH) complicating primary catastrophic anti-phospholipid syndrome (CAPS) was diagnosed in a 50-year-old female patient. Treatment strategies are limited for this often life-threatening autoimmune disease that requires aggressive immunosuppression. In the absence of clinically validated treatment strategies, high-dose steroids associated with plasma exchange and eventually intravenous immunoglobulins were used to manage the disease. Its severity prompted the initiation of rituximab that was administered weekly for four consecutive weeks. Anticoagulation therapy, on the other hand, needed to be discontinued due to the major haemorrhagic episodes. This combination treatment provided an effective control of the CAPS-associated DAH and helped achieve clinical remission.

We report the case of a middle age patient presenting with Tako-Tsubo cardiomyopathy (TTC) complicated by cardiogenic shock that was successfully handled with milrinone. A 64-year old man presented with cardiogenic shock after benzodiazepine and alcohol intoxication. A slight elevation of troponin and typical left ventricular ballooning without coronary lesions suggested TTC. Within a few hours milrinone infusion normalized the cardiac index. TTC is responsible for severe transient left ventricular dysfunction occurring after physical or psychological stress. The major pathophysiological mechanism involved is disproportionate catecholamine secretion, which may stun the myocardium. We considered if treatment of this unique physiopathology with catecholamines could be dangerous in these patients and if alternative inotropes such as milrinone should be preferred.

AIMS: To assess long-term outcomes and the management of critical left-sided infective endocarditis (IE) and evaluate the impact of surgery. METHODS AND RESULTS: Among the 198 patients included prospectively for IE across 33 adult intensive care units (ICU) in France from 1 April 2007 to 1 October 2008, 137 (69%) were dead at a median follow-up time of 59.5 months. Characteristics significantly associated with mortality were: Sepsis-related Organ-Failure Assessment (SOFA) score at ICU admission [Hazard ratio (HR), 95% Confidence Interval (CI) of 1.43 (0.79-2.59) for SOFA 5-9; 2.01 (1.05-3.85) for SOFA 10-14; 3.53 (1.75-7.11) for SOFA 15-20; reference category SOFA 0-4; P = 0.003]; prosthetic mechanical valve IE [HR 2.01; 95% CI 1.09-3.69, P = 0.025]; vegetation size ≥15 mm [HR 1.64; 95% CI 1.03-2.63, P = 0.038]; and cardiac surgery [HR (95%CI), 0.33 (0.16-0.67) for surgery ≤1 day after IE diagnosis; 0.61 (0.29-1.26) for surgery 2-7 days after IE diagnosis; 0.42 (0.21-0.83) for surgery >7 days after IE diagnosis; reference category no surgery; P = 0.005]. One hundred and three (52%) patients underwent cardiac surgery after a median time of 6 (16) days. Independent predictors of surgical intervention on multivariate analysis were: age ≤60 years [Odds ratio (OR) 5.30; 95% CI (2.46-11.41), P < 0.01], heart failure [OR 3.27; 95% CI (1.03-10.35), P = 0.04], cardiogenic shock [OR 3.31; 95% CI (1.47-7.46), P = 0.004], septic shock [OR 0.25; 95% CI (0.11-0.59), P = 0.002], immunosuppression [OR 0.15; 95% CI (0.04-0.55), P = 0.004], and diagnosis before or within 24 h of ICU admission [OR 2.81; 95% CI (1.14-6.95), P = 0.025]. SOFA score calculated the day of surgery was the only independently associated factor with long-term mortality [HR (95% CI) 1.59 (0.77-3.28) for SOFA 5-9; 3.56 (1.71-7.38) for SOFA 10-14; 11.58 (4.02-33.35) for SOFA 15-20; reference category SOFA 0-4; P < 0.0001]. Surgical timing was not associated with post-operative outcomes. Of the 158 patients with a theoretical indication for surgery, the 58 deemed not fit had a 95% mortality rate. CONCLUSION: Mortality in patients with critical IE remains unacceptably high. Factors associated with long-term outcomes are the severity of multiorgan failure, prosthetic mechanical valve IE, vegetation size ≥15 mm, and surgical treatment. Up to one-third of potential candidates do not undergo surgery and these patients experience extremely high mortality rates. The strongest independent predictor of post-operative mortality is the pre-operative multiorgan failure score while surgical timing does not seem to impact on outcomes.
