Aim: Donation after cardiac death (DCD) has been proposed to partly overcome the organ donor shortage. In liver transplantation, the additional warm ischemia linked to DCD procurement may promote higher rate of primary non-function and ischemic type biliary lesions. In this study we reviewed the results of DCD liver transplantation at the University of Liège. Patients and Methods: From 2003 to 2007, 13 controlled DCD liver transplantations were consecutively performed. The records of all donors and recipients were retrospectively reviewed, particularly evaluating the outcome and the occurrence of biliary complications. Mean follow-up was 25 months. Results: Mean donor age was 51 years and their mean intensive care stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 min. Mean time between cardiac arrest and arterial flush was 7.7 min. No touch period was 2 to 5 min. Mean graft cold ischemia was 295 min and mean suture warm ischemia was 38 min. Postoperatively there was no primary non-function. Mean peak transaminase was 2,546 UI/ml. Patient and graft survival was 100% at one year. Two patients (15%) developed graft main bile duct stenosis and underwent endoscopic management. No patient developed symptomatic intrahepatic bile duct strictures or needed retransplantation in the follow-up. Conclusions: The experience of the transplantation department of the University of Liege confirms that controlled DCD donors may be a valuable source of transplantable liver grafts, in case of short procurement warm ischemia and short transplant cold ischemia.

BACKGROUND: There is uncertainty on the effect of different dialysis modalities for the treatment of patients with acute kidney injury (AKI), admitted to the intensive care unit (ICU). This controlled clinical trial performed in the framework of the multicentre SHARF 4 study (Stuivenberg Hospital Acute Renal Failure) aimed to investigate the outcome in patients with AKI, stratified according to severity of disease and randomized to different treatment options. METHODS: This was a multicentre prospective randomized controlled trial with stratification according to severity of disease expressed by the SHARF score. ICU patients were eligible for inclusion when serum creatinine was >2 mg/dL, and RRT was initiated. The selected patients were randomized to intermittent (IRRT) or continuous renal replacement therapy (CRRT). RESULTS: A total of 316 AKI patients were randomly assigned to IRRT (n = 144) or CRRT (n = 172). The mean age was 66 (range 18-96); 59% were male. Intention-to-treat analysis revealed a mortality of 62.5% in IRRT compared to 58.1% in CRRT (P = 0.430). No difference between IRRT and CRRT could be observed in the duration of ICU stay or hospital stay. In survivors, renal recovery at hospital discharge was comparable between both groups. Multivariate analysis, including the SHARF score, APACHE II and SOFA scores for correction of disease severity, showed no difference in mortality between both treatment modalities. This result was confirmed in pre-specified subgroup analysis (elderly, patients with sepsis, heart failure, ventilation) and after exclusion of possible confounders (early mortality, delayed ICU admission). CONCLUSIONS: Modality of RRT, either CRRT or IRRT, had no impact on the outcome in ICU patients with AKI. Both modalities need to be considered as complementary in the treatment of AKI (Clinical Trial: SHARF 4, NCT00322933, http://ClinicalTrials.gov). [less ▲]

Sepsis, severe sepsis and septic shock were thought to be provoked by an overwhelming inflammation in response to an infectious process. This was documented in several animal studies. However, in human sepsis, excess of inflammation is hard to be observed. Compartimentalization of the host response rather favors a systemic anti-inflammatory climate. Clinical situations are complex: on one hand, virulence factors of microorganisms can directly harm the host tissues, divert the defence mechanisms or distract the control mechanisms of the host, preventing the normal interaction of endogenous mediators. On the other hand, septic shock mostly occurs in patients experiencing previous organic or functional vital failures before the development of infection. The vulnerability of the patient appears therefore to be a key point in the severity of the disease. Enhancing the host defence mechanisms rather than inhibiting the inflammatory reaction may become a preferential option. [less ▲]

OBJECTIVES: To validate the SAPS 3 admission score in an independent general intensive care case mix and to compare its performances with the APACHE II and the SAPS II scores. DESIGN: Cohort observational study. SETTING: A 26-bed general ICU from a Tertiary University Hospital. PATIENTS AND PARTICIPANTS: Eight hundred and fifty-one consecutive patients admitted to the ICU over an 8-month period. Of these patients, 49 were readmissions, leaving 802 patients for further analysis. INTERVENTION: None. MEASUREMENTS AND RESULTS: APACHE II, SAPS II and SAPS 3 variables were prospectively collected; scores and their derived probability of death were calculated according to their original manuscript description. The discriminative power was assessed using the area under the ROC curve (AUROC) and calibration was verified with the Hosmer-Lemeshow goodness-of-fit test. The AUROC of the APACHE II model (AUROC = 0.823) was significantly lower than those of the SAPS II (AUROC = 0.850) and SAPS 3 models (AUROC = 0.854) (P = 0.038). The calibration of the APACHE II model (P = 0.037) and of the SAPS 3 global model (P = 0.035) appeared unsatisfactory. On the contrary, both SAPS II model and SAPS 3 model customised for Central and Western Europe had a good calibration. However, in our study case mix, SAPS II model tended to overestimate the probability of death. CONCLUSION: In this study, the SAPS 3 admission score and its prediction model customised for Central and Western Europe was more discriminative and better calibrated than APACHE II, but it was not significantly better than the SAPS II.

The cyclic appearance of dynamic left ventricular outflow tract obstruction during mechanical ventilation, according to the phasic changes in preload, is described in this article. Hemodialysis-induced fluid removal resulted in preload dependence as evidenced by the pulse pressure variation in a 56-year-old critically ill patient. The clinical picture was suggestive of myocardial failure. Transthoracic echocardiography disclosed dynamic left ventricular outflow tract obstruction associated with systolic anterior motion of the mitral valve. Progressive fluid restitution resulted in a parallel decrease in both the degree of dynamic obstruction and pulse pressure variation. During fluid loading, dynamic obstruction disappeared at first during the inspiratory phase of intermittent positive pressure ventilation corresponding to the phasic increase in left ventricular preload. Further fluid loading resulted in the disappearance of dynamic obstruction during both inspiratory and expiratory phase of intermittent positive pressure ventilation. This is the first reported case clearly relating left ventricular outflow tract dynamic obstruction to preload dependence during mechanical ventilation in a critically ill patient without predisposing anatomical factor.

OBJECTIVE: To assess the temporal relationship between ICU-acquired infection (IAI) and the prevalence and severity of organ dysfunction or failure (OD/F). DESIGN AND SETTING: Observational, single center study in a mixed intensive care unit of a university hospital. PATIENTS: We analyzed 1,191 patients hospitalized for more than 2 days during a 2-year observation period: 845 did not acquire IAI, 306 of whom had infection on admission (IOA); 346 did acquire IAI, 125 of whom had IOA. MEASUREMENTS AND RESULTS: The SOFA score was calculated daily, both SOFAmax, the sum of the worst OD/F during the ICU stay, and SOFApreinf, the sum of the worst OD/F existing before the occurrence of the first IAI. The SAPS II and SOFA score of the first 24 h were significantly higher in patients with than in those without IAI. SOFApreinf of IAI patients was also higher than the SOFAmax of patients without IAI both in patients with (12.1+/-4.6 vs. 8.9+/-4.7) and those without IOA (9.2+/-4.0 vs. 6.7+/-3.5). SOFApreinf represented 85.7% of the value of SOFAmax in patients with IAI. SOFApreinf increased significantly with the occurrence of sepsis, severe sepsis, or septic shock during ICU stay. Severe sepsis and septic shock during ICU stay as well as SOFApreinf were part of the factors associated with hospital mortality. CONCLUSIONS: IAI is significantly associated with hospital mortality; however, its contribution to OD/F is minor. Moreover, severity of IAI seems to be related to previous health status. [less ▲]

Background: Disentangling the vegetative state from the minimally conscious state is often difficult when relying only on behavioral observation. In this study, we explored a new active evoked related potentials paradigm as an alternative method for the detection of voluntary brain activity. Methods: The participants were 22 right-handed patients (10 traumatic) diagnosed as being in a vegetative state (VS) (n 8) or in a minimally conscious state (MCS) (n 14). They were presented sequences of names containing the patient’s own name or other names, in both passive and active conditions. In the active condition, the patients were instructed to count her or his own name or to count another target name. Results: Like controls, MCS patients presented a larger P3 to the patient’s own name, in the passive and in the active conditions. Moreover, the P3 to target stimuli was higher in the active than in the passive condition, suggesting voluntary compliance to task instructions like controls. These responses were even observed in patients with low behavioral responses (e.g., visual fixationand pursuit). In contrast, no P3 differences between passive and active conditions were observed for VS patients. Conclusions: The present results suggest that active evoked-related potentials paradigms may permit detection of voluntary brain function in patients with severe brain damage who present with a disorder of consciousness, even when the patient may present with very limited to questionablyany signs of awareness.

Systemic inflammatory response syndrome (SIRS) can be related to acute inflammatory conditions that can be sometimes missed and inappropriately managed as severe infections. We report a case of Churg Strauss Syndrome (CSS), presenting as septic shock with acute onset of fever and multiple organ failure including pulmonary involvement with severe hypoxemia, hypotension requiring vasoactive support and acute renal failure. Antibiotics were discontinued and intravenous steroids allowed a rapid clinical improvement in close relationship with the fall in circulating eosinophils count. [less ▲]

BACKGROUND: Studies have suggested worse outcomes in transfused patients and improved outcomes in patients managed with restricted blood transfusion strategies. The authors investigated the relation of blood transfusion to mortality in European intensive care units (ICUs). METHODS: The Sepsis Occurrence in Acutely Ill Patients study was a multicenter, observational study that included all adult patients admitted to 198 European ICUs between May 1 and May 15, 2002 and followed them until death, until hospital discharge, or for 60 days. Patients were classified depending on whether they had received a blood transfusion at any time during their ICU stay. RESULTS: Of 3,147 patients, 1,040 (33.0%) received a blood transfusion. These patients were older (mean age, 62 vs. 60 yr; P = 0.035) and were more likely to have liver cirrhosis or hematologic cancer, to be a surgical admission, and to have sepsis. They had a longer duration of ICU stay (5.9 vs. 2.5 days; P < 0.001) and a higher ICU mortality rate (23.0 vs. 16.3%; P < 0.001) but were also more severely ill on admission (Simplified Acute Physiology Score II, 40.2 vs. 34.7; P < 0.001; Sequential Organ Failure Assessment score, 6.5 vs. 4.5; P < 0.001). There was a direct relation between the number of blood transfusions and the mortality rate, but in multivariate analysis, blood transfusion was not significantly associated with a worse mortality rate. Moreover, in 821 pairs matched according to a propensity score, there was a higher 30-day survival rate in the transfusion group than in the other patients (P = 0.004). CONCLUSION: This observational study does not support the view that blood transfusions are associated with increased mortality rates in acutely ill patients. [less ▲]
