Outcomes of re-referrals of patients with alcohol-associated liver disease, who were previously declined for liver transplantation. Liver Transpl 2024; 30:254-261. [PMID: 37772886 DOI: 10.1097/lvt.0000000000000274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 08/28/2023] [Indexed: 09/30/2023]
Abstract
Since 2018, our program has utilized specific psychosocial criteria and a multidisciplinary approach to assess patients for liver transplant due to alcohol-associated liver disease (ALD), rather than the 6-month abstinence rule alone. If declined based on these criteria, specific recommendations are provided to patients and their providers regarding goals for re-referral to increase the potential for future transplant candidacy. Recommendations include engagement in treatment for alcohol use disorder, serial negative biomarker testing, and maintenance of abstinence from alcohol. In our current study, we evaluate the outcomes of patients with ALD, who were initially declined upon assessment and re-referred to our program. This is a retrospective cohort study that includes 98 patients with ALD, who were previously declined for liver transplantation and were subsequently re-referred for liver transplant assessment between May 1, 2018, and December 31, 2021. We assess the outcomes of patients who were re-referred including acceptance for transplantation following a second assessment. Of the 98 patients who were re-referred, 46 (46.9%) fulfilled the recommendations made and proceeded to further medical evaluation. Nine were eventually transplanted; others are listed and are waiting for transplant. The presence of a partner was independently associated with a higher rate of acceptance (OR 0.16, 95% CI: 0.03-0.97, p = 0.05). Most of the patients who did not proceed further (n = 52) were declined again due to ALD contraindications (n = 33, 63.4%), including ongoing drinking and lack of engagement in recommended addiction treatment. Others had medical contraindications (11.2%), clinically improved (6.1%), had adherence issues (5.1%), or lack of adequate support (2%). Patients with ALD previously declined for a liver transplant can be re-referred and successfully accepted for transplantation by fulfilling the recommendations made by the multidisciplinary team. Important factors including ongoing abstinence, engagement in addiction treatment, and social support are key for successful acceptance.

Outcomes of critically ill patients with liver failure who require mechanical ventilation: A retrospective, single-center study. Health Sci Rep 2024; 7:e1926. [PMID: 38469112 PMCID: PMC10925802 DOI: 10.1002/hsr2.1926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 11/28/2023] [Accepted: 02/03/2024] [Indexed: 03/13/2024] Open
Abstract
Background and Aims Critically ill patients with liver failure have high mortality. Besides the management of organ-specific complications, liver transplantation constitutes a definitive treatment. However, clinicians may hesitate to introduce mechanical ventilation for patients on liver transplantation waitlists because of poor prognosis. This study investigated the outcomes of intensive care and ventilation support therapy effects in patients with liver failure. Methods This single-center study retrospectively enrolled 32 consecutive patients with liver failure who were admitted to the intensive care unit from January 2014 to December 2020. The medical records were reviewed and analyzed retrospectively for Acute Physiologic and Chronic Health Evaluation (APACHE)-II. The model for end-stage liver disease scores, 90-day mortality, and survival was assessed using the Kaplan-Meier method. Results The average patient age was 45.5 ± 20.1 years, and 53% of patients were women. On intensive care unit admission, APACHE-II and model for end-stage liver disease scores were 20 and 28, respectively. Among 13 patients considered for liver transplantation, 4 received transplants. Thirteen patients (40.6%) were intubated and mechanically ventilated in the intensive care unit. The 90-day mortality rate of patients with and without mechanical ventilation in the intensive care unit (13, 61.5% vs. 19, 47.4%, p = 0.4905) was similar. APACHE-II score >21 was an independent predictor of mechanical ventilation requirement in patients with liver failure during intensive care unit stay. Conclusion Although critically ill patients with liver failure are at risk of multiorgan failure with poor outcomes, mechanical ventilation did not negatively affect the 90-day mortality or performance rates of liver transplantation. Clinicians should consider mechanical ventilation-based life support in critically ill patients with liver failure who are awaiting liver transplantation.

Abstract
End-stage liver disease (ESLD) is characterized by the deterioration of liver function and a subsequent high mortality rate. Studies have investigated the use of adult stem cells to treat ESLD. Here, a systematic review and meta-analysis was conducted to determine the efficacy of a combination therapy with adult stem cell transplantation and traditional medicine for treating ESLD. Four databases-including PubMed, Web of Science, Embase, and Cochrane Library-were investigated for studies published before January 31, 2021. The main outcome indicators were liver function index, model for end-stage liver disease (MELD) scores, and Child‒Turcotte‒Pugh (CTP) scores. Altogether, 1604 articles were retrieved, of which eight met the eligibility criteria; these studies included data for 579 patients with ESLD. Combination of adult stem cell transplantation with conventional medicine significantly improved its efficacy with respect to liver function index, CTP and MELD scores, but this effect gradually decreased over time. Moreover, a single injection of stem cells was more effective than two injections with respect to MELD and CTP scores and total bilirubin (TBIL) and albumin (ALB) levels, with no significant difference in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. With respect to the TBIL levels, patients receiving mononuclear cells (MNCs) experienced a significantly greater therapeutic effect-starting from twenty-four weeks after the treatment-whereas with respect to ALB levels, CD34+ autologous peripheral blood stem cells (CD34+ APBSCs) and MNCs had similar therapeutic effects. Severe complications associated with adult stem cell treatment were not observed. Although the benefits of combination therapy with respect to improving liver function were slightly better than those of the traditional treatment alone, they gradually decreased over time.Systematic review registration: PROSPERO registration number: CRD42021238576.

Abstract
OBJECTIVES The prevalence of liver cirrhosis is increasing, and many patients have acute conditions requiring consideration of intensive care. This study aims to: (a) report the outcome at 12 months of patients with cirrhosis admitted to ICU, (b) identify factors predictive of long-term mortality and (c) evaluate the ability of scoring systems to predict long-term outcome. DESIGN Observational cohort study. SETTING General adult critical care unit in a UK teaching hospital. PATIENTS Eighty-four patients admitted to critical care between June 2012 and December 2013. PRIMARY OUTCOME MEASURES Cumulative survival at ICU discharge, hospital discharge and 12 months. RESULTS Eighty-four patients with diagnosed cirrhosis were followed up at 12 months. Clinical variables collected at ICU admission were entered into a multivariate regression analysis for mortality and eight predetermined scoring systems calculated. Cumulative survival at ICU discharge, hospital discharge and 12 months was 64.8, 47.1 and 44.1%, respectively. Twelve months of cumulative survival in patients with Child-Pugh class A was 100%, class B was 50% and class C was 25% (log rank p = 0.002). Independent predictors of mortality at 12 months were lactate, bilirubin, PT ratio and age. The Child-Pugh + Lactate score was modified to produce an objective score comprising Albumin, Bilirubin and Clotting (PT ratio) added to serum lactate concentration in mmol L-1 (ABC + Lactate). This score was the best predictor of 12-month survival, with an AUC of 0.83. A proposed classification by ABC + Lactate score was highly significant (p = 0.001), with those in the highest class having ICU mortality of 75% and hospital and 12-month mortality of 93%. CONCLUSIONS Patients with cirrhosis admitted to ICU have high initial mortality but low mortality after hospital discharge. Child-Pugh class at ICU admission predicts outcome at 12 months. The ABC + Lactate classification system may be useful in identifying critically ill cirrhotic patients with very high long-term mortality.

Predictors of Mortality in the Critically Ill Cirrhotic Patient: Is the Model for End-Stage Liver Disease Enough? J Am Coll Surg 2016; 224:276-282. [PMID: 27887981 DOI: 10.1016/j.jamcollsurg.2016.11.005] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2016] [Revised: 10/26/2016] [Accepted: 11/15/2016] [Indexed: 12/21/2022]
Abstract
BACKGROUND Critically ill cirrhotics require liver transplantation urgently, but are at high risk for perioperative mortality. The Model for End-stage Liver Disease (MELD) score, recently updated to incorporate serum sodium, estimates survival probability in patients with cirrhosis, but needs additional evaluation in the critically ill. The purpose of this study was to evaluate the predictive power of ICU admission MELD scores and identify clinical risk factors associated with increased mortality. STUDY DESIGN This was a retrospective review of cirrhotic patients admitted to the ICU between January 2011 and December 2014. Patients who were discharged or underwent transplantation (survivors) were compared with those who died (nonsurvivors). Demographic characteristics, admission MELD scores, and clinical risk factors were recorded. Multivariate regression was used to identify independent predictors of mortality, and measures of model performance were assessed to determine predictive accuracy. RESULTS Of 276 patients who met inclusion criteria, 153 were considered survivors and 123 were nonsurvivors. Survivor and nonsurvivor cohorts had similar demographic characteristics. Nonsurvivors had increased MELD, gastrointestinal bleeding, infection, mechanical ventilation, encephalopathy, vasopressors, dialysis, renal replacement therapy, requirement of blood products, and ICU length of stay. The MELD demonstrated low predictive power (c-statistic 0.73). Multivariate analysis identified MELD score (adjusted odds ratio [AOR] = 1.05), mechanical ventilation (AOR = 4.55), vasopressors (AOR = 3.87), and continuous renal replacement therapy (AOR = 2.43) as independent predictors of mortality, with stronger predictive accuracy (c-statistic 0.87). CONCLUSIONS The MELD demonstrated relatively poor predictive accuracy in critically ill patients with cirrhosis and might not be the best indicator for prognosis in the ICU population. Prognostic accuracy is significantly improved when variables indicating organ support (mechanical ventilation, vasopressors, and continuous renal replacement therapy) are included in the model.

Abstract
Data regarding transplantation outcomes in ventilated intensive care unit (ICU)-dependent patients with end-stage liver disease (ESLD) are conflicting. This single-center cohort study investigated the outcomes of patients with ESLD who were intubated with mechanical support before liver transplantation (LT). The ICU plus intubation group consisted of 42 patients with decompensated cirrhosis and mechanical ventilation before transplantation. LT was considered for intubated ICU patients if the fraction of inspired oxygen was ≤40% with a positive end-expiratory pressure ≤ 10, low pressor requirements, and the absence of an active infection. Intubated ICU patients were compared to 80 patients requiring ICU admission before transplantation without intubation and to 126 matched non-ICU-bound patients. Patients requiring ICU care with intubation and ICU care alone had more severe postoperative complications than non-ICU-bound patients. Intubation before transplantation was associated with more postoperative pneumonias (15% in intubated ICU transplant candidates, 5% in ICU-bound but not intubated patients, and 3% in control group patients; P = 0.02). Parameters of reperfusion injury and renal function on postoperative day (POD) 2 and POD 7 were similar in all groups. Bilirubin levels were higher in the ICU plus intubation group at POD 2 and POD 7 after transplantation but were normalized in all groups within 3 months. The ICU plus intubation group versus the ICU-only group and the non-ICU group had decreased 1-, 3-, and 5-year graft survival (81% versus 84% versus 92%, 76% versus 78% versus 87%, and 71% versus 77% versus 84%, respectively; P = 0.19), but statistical significance was not reached. A Glasgow coma scale score of <7 versus >7 before transplantation was associated with high postoperative mortality in ICU-bound patients requiring intubation (38% versus 23%; P = 0.01). In conclusion, ICU admission and mechanical ventilation should not be considered contraindications for LT. With careful patient selection, acceptable long-term outcomes can be achieved despite increased postoperative complications.

Abstract
OBJECTIVE When used to prolong life without achieving a benefit meaningful to the patient, critical care is often considered "futile." Although futile treatment is acknowledged as a misuse of resources by many, no study has evaluated its opportunity cost, that is, how it affects care for others. Our objective was to evaluate delays in care when futile treatment is provided. DESIGN For 3 months, we surveyed critical care physicians in five ICUs to identify patients that clinicians identified as receiving futile treatment. We identified days when an ICU was full and contained at least one patient who was receiving futile treatment. For those days, we evaluated the number of patients waiting for ICU admission more than 4 hours in the emergency department or more than 1 day at an outside hospital. SETTING One health system that included a quaternary care medical center and an affiliated community hospital. PATIENTS Critically ill patients. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Boarding time in the emergency department and waiting time on the transfer list. Thirty-six critical care specialists made 6,916 assessments on 1,136 patients of whom 123 were assessed to receive futile treatment. A full ICU was less likely to contain a patient receiving futile treatment compared with an ICU with available beds (38% vs 68%, p < 0.001). On 72 (16%) days, an ICU was full and contained at least one patient receiving futile treatment. During these days, 33 patients boarded in the emergency department for more than 4 hours after admitted to the ICU team, nine patients waited more than 1 day to be transferred from an outside hospital, and 15 patients canceled the transfer request after waiting more than 1 day. Two patients died while waiting to be transferred. CONCLUSIONS Futile critical care was associated with delays in care to other patients.

OBJECTIVE To determine the evolution of the outcome of patients with cirrhosis and septic shock. DESIGN A 13-year (1998-2010) multicenter retrospective cohort study of prospectively collected data. SETTING The Collège des Utilisateurs des Bases des données en Réanimation (CUB-Réa) database recording data related to admissions in 32 ICUs in Paris area. PATIENTS Thirty-one thousand two hundred fifty-one patients with septic shock were analyzed; 2,383 (7.6%) had cirrhosis. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Compared with noncirrhotic patients, patients with cirrhosis had higher Simplified Acute Physiology Score II (63.1 ± 22.7 vs 58.5 ± 22.8, p < 0.0001) and higher prevalence of renal (71.5% vs 54.8%, p < 0.0001) and neurological (26.1% vs 19.5%, p < 0.0001) dysfunctions. Over the study period, in-ICU and in-hospital mortality was higher in patients with cirrhosis (70.1% and 74.5%) compared with noncirrhotic patients (48.3% and 51.7%, p < 0.0001 for both comparisons). Cirrhosis was independently associated with an increased risk of death in ICU (adjusted odds ratio = 2.524 [2.279-2.795]). In patients with cirrhosis, factors independently associated with in-ICU mortality were as follows: admission for a medical reason, Simplified Acute Physiology Score II, mechanical ventilation, renal replacement therapy, spontaneous bacterial peritonitis, positive blood culture, and infection by fungus, whereas direct admission and admission during the most recent midterm period (2004-2010) were associated with a decreased risk of death. From 1998 to 2010, prevalence of septic shock in patients with cirrhosis increased from 8.64 to 15.67 per 1,000 admissions to ICU (p < 0.0001) and their in-ICU mortality decreased from 73.8% to 65.5% (p = 0.01) despite increasing Simplified Acute Physiology Score II. In-ICU mortality decreased from 84.7% to 68.5% for those patients placed under mechanical ventilation (p = 0.004) and from 91.2% to 78.4% for those who received renal replacement therapy (p = 0.04). CONCLUSIONS The outcome of patients with cirrhosis and septic shock has markedly improved over time, akin to the noncirrhotic population. In 2010, the in-ICU survival rate was 35%, which now fully justifies to admit these patients to ICU.

Clin Res Hepatol Gastroenterol 2013; 37:455-66.

Abstract
Mortality is increased in cirrhotic patients admitted in ICU whatever the admission reason. Prognosis scores assessed in critically ill cirrhotic patients in ICU can be classified in three main categories: liver-specific (CTP and MELD) scores, general (SAPS II and APACHE) scores, and organ failure (OSF and SOFA) scores. The components of the liver-specific scores can be influenced by the acute disease indicating the admission to ICU but those of the non liver-specific scores can be influenced by the underlying liver cirrhosis. Many studies reported that organ failure scores are the best predictors of outcome in cirrhotic patients in ICU. We may wonder if cirrhotic patients with acute organ failures should receive prioritization for organ allocation to save their life or should be denied for a potential futile LT. According to recent studies, the SOFA score is associated with a higher risk of death for patients waiting for LT but could not be associated with a worse outcome after LT. It becomes of paramount importance to correctly identify the cirrhotic patients who will maximally benefit from LT after admission to ICU. The EASL-CLIF Consortium defines the CLIF-SOFA score, redefining the SOFA score with cut-off levels based on mortality prediction. The CLIF-SOFA could represent the ideal score in ICU since it is based on organ failures with cut-off values specifically identified in cirrhotic patients. The validation of the CLIF-SOFA score in critically ill cirrhotic patients admitted to ICU and its usefulness to identify patients who could benefit from LT should be the next steps.

Abstract
Acute liver failure in ICU patients is an often fatal condition in which many patients may die of multiple organ failure in the absence of liver transplantation. In this setting, cardiac injury may be associated with or precipitate a fatal outcome. Troponin-I is a well-established, specific, and sensitive surrogate of acute coronaropathy, with both diagnostic and prognostic value. Troponin-I elevation in acute liver failure patients is common, ranging from 60 to 75%, and probably multifactorial. Despite a previous well-conducted US study showing that elevated troponin-I is associated with an independent risk of poor outcome and mortality, a recent UK study did not confirm these data and reported contradictory results. Troponin-I elevation observed in acute liver failure may therefore not represent true myocardial injury and may be better viewed as a marker of metabolic stress. The debate on the significance of elevated troponin-I in acute liver failure patients is revived.

Abstract
Acute-on-chronic liver failure (ACLF) is an increasingly recognised entity encompassing an acute deterioration of liver function in patients with cirrhosis, which is usually associated with a precipitating event and results in the failure of one or more organs and high short term mortality. Prospective data to define this is lacking but there is a large body of circumstantial evidence suggesting that this condition is a distinct clinical entity. From the pathophysiologic perspective, altered host response to injury and infection play important roles in its development. This review focuses upon the current understanding of this syndrome from the clinical, prognostic and pathophysiologic perspectives and indicates potential biomarkers and therapeutic targets for intervention.

Abstract
INTRODUCTION Acute deterioration of cirrhosis is associated with high mortality rates particularly in the patients who develop organ failure (OF), a condition that is referred to as acute-on-chronic liver failure (ACLF), which is currently not completely defined. This study aimed to determine the role of predisposing factors, the nature of the precipitating illness and inflammatory response in the progression to OF according to the PIRO (predisposition, injury, response, organ failure) concept to define the risk of in-hospital mortality. METHODS A total of 477 patients admitted with acute deterioration of cirrhosis following a defined precipitant over a 5.5-year period were prospectively studied. Baseline clinical, demographic and biochemical data were recorded for all patients and extended serial data from the group that progressed to OF were analysed to define the role of PIRO in determining in-hospital mortality. RESULTS One hundred and fifty-nine (33%) patients developed OF, of whom 93 patients died (58%) compared with 25/318 (8%) deaths in the non-OF group (P < 0.0001). Progression to OF was associated with more severe underlying liver disease and inflammation. In the OF group, previous hospitalisation (P of PIRO); severity of inflammation and lack of its resolution (R of PIRO); and severity of organ failure (O of PIRO) were associated with significantly greater risk of death. In the patients who recovered from OF, mortality at three years was almost universal. CONCLUSIONS The results of this prospective study shows that the occurrence of OF alters the natural history of cirrhosis. A classification based on the PIRO concept may allow categorization of patients into distinct pathophysiologic and prognostic groups and allow a multidimensional definition of ACLF.

Abstract
PURPOSE Critically-ill patients with end-stage liver disease (ESLD) are at high risk for death during intensive care unit hospitalization, and currently available prognostic models have limited accuracy in this population. We aimed to identify variables associated with in-hospital mortality among critically ill ESLD patients and to develop and validate a simple, parsimonious model for bedside use. MATERIALS AND METHODS We performed a retrospective chart review of 653 intensive care unit admissions for ESLD patients; modeled in-hospital mortality using multivariable logistic regression; and compared the predictive ability of several different models using the area under receiver operating characteristic (AU-ROC) curves. RESULTS Multivariable predictors of in-hospital mortality included Model for End-stage Liver Disease (MELD) score, Acute Physiology and Chronic Health Evaluation (APACHE) II score, mechanical ventilation, and gender; there was also an interaction between MELD score and gender (P < .02). MELD alone had better discrimination (AU-ROC 0.83) than APACHE II alone (AU-ROC 0.76), and adding mechanical ventilation to MELD achieved the single largest increase in model discrimination (AU-ROC 0.85; P < .01). In a parsimonious, 2-predictor model, higher MELD scores (OR 1.14 per 1-point increase; 95% CI 1.11-1.16), and mechanical ventilation (OR 6.20; 95% CI 3.05-12.58) were associated with increased odds of death. Model discrimination was also excellent in the validation cohort (AU-ROC 0.90). CONCLUSIONS In critically ill ESLD patients, a parsimonious model including only MELD and mechanical ventilation is more accurate than APACHE II alone for predicting in-hospital mortality. This simple bedside model can provide clinicians and patients with valuable prognostic information for medical decision-making.

Abstract
BACKGROUND The mortality of patients suffering from acute decompensated liver disease treated in the intensive care unit (ICU) varies between 50% and 100%. Previously published data suggest that liver-specific score systems are less accurate compared with the ICU-specific scoring systems acute physiology and chronic health evaluation II (APACHE II) and simplified organ failure assessment (SOFA) in predicting outcome. We hypothesized that in a Scandinavian cohort of ICU patients, APACHE II, SOFA, and simplified acute physiology score (SAPS II) were superior to predict outcome compared with the Child-Pugh score. METHODS A single-centre retrospective cohort analysis was conducted in a university-affiliated ICU. Eighty-seven adult patients with decompensated liver alcoholic cirrhosis were admitted from January 2007 to January 2010. RESULTS The patients were severely ill with median scores: SAPS II 60, SOFA (day 1) 11, APACHE II 31, and Child-Pugh 12. Receiver operating characteristic curves area under curve was 0.79 for APACHE II, 0.83 for SAPS II, and 0.79 for SOFA (day 1) compared with 0.59 for Child-Pugh. In patients only in need of mechanical ventilation, the 90-day mortality was 76%. If respiratory failure was further complicated by shock treated with vasopressor agents, the 90-day mortality increased to 89%. Ninety-day mortality for patients in need of mechanical ventilation, vasoactive medication, and renal replacement therapy because of acute kidney injury was 93%. CONCLUSION APACHE II, SAPS II, and SOFA were better at predicting mortality than the Child-Pugh score. With three or more organ failures, the ICU mortality was > 90%. APACHE II > 30, SAPS II > 60, and SOFA at day 1 > 12 were all associated with a mortality of > 90%. Referral criteria of patients suffering from decompensated alcoholic liver disease should be revised.

Abstract
OBJECTIVE To examine how the outcomes of cirrhotic patients admitted to an ICU have changed over time. METHODS A retrospective study in a medical ICU during two separate 3-year periods [period 1 (P1): 1995-1998 and period 2 (P2): 2005-2008]. RESULTS A total of 56 cirrhotic patients were admitted during P1 and 138 during P2, accounting for 2.3 and 4.5% of the total ICU admissions (P<0.01). Patients' characteristics were markedly different between the two periods: previous functional status improved (Knaus scale, A/B/C/D: P1 - 7.1%/53.6%/35.7%/3.6% vs. P2 - 28.2%/47.8%/22.5%/1.5%, P<0.01), the number of comorbidities decreased (Charlson: 1.79±2.22 vs. 1.02±1.40, P=0.02), the severity of cirrhosis increased [Child-Pugh: 8 (7-13) vs. 11 (8-13), P=0.04; Model for End-Stage Liver Disease: 16 (12-28) vs. 22 (15-31), P=0.02], and acute organ dysfunctions increased (Sequential Organ Failure Assessment: 7.3±5.6 vs. 11.3±5.5, P<0.01). The crude in-ICU mortality was similar during the two periods (39.3 vs. 41.3%, P=0.92). However, after adjustment for severity, in-ICU mortality was markedly decreased during P2 (odds ratio: 0.36 [0.15; 0.88], P=0.02). CONCLUSION Cirrhotic patients admitted to the ICU have an improved outcome despite increased severity of liver disease. This improvement is associated with a higher selection according to their previous functional status and comorbidities.

Abstract
BACKGROUND The importance of intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) in cirrhotic patients with septic shock is not well studied. We evaluated the relationship between IAP and APP and outcomes of cirrhotic septic patients, and assessed the ability of these measures compared to other common resuscitative endpoints to differentiate survivors from nonsurvivors. METHODS This study was a post hoc analysis of a randomized double-blind placebo-controlled trial in which mean arterial pressure (MAP), central venous oxygen saturation (ScvO2) and IAP were measured every 6 h in 61 cirrhotic septic patients admitted to the intensive care unit. APP was calculated as MAP - IAP. Intra-abdominal hypertension (IAH) was defined as mean IAP ≥ 12 mmHg, and abdominal hypoperfusion as mean APP < 60 mmHg. Measured outcomes included ICU and hospital mortality, need for renal replacement therapy (RRT) and ventilator- and vasopressor-free days. RESULTS IAH prevalence on the first ICU day was 82%, and incidence in the first 7 days was 97%. Compared to patients with normal IAP, IAH patients had significantly higher ICU mortality (74.0% vs. 27.3%, p = 0.005), required more RRT (78.0% vs. 45.5%, p = 0.06) and had lower ventilator- and vasopressor-free days. On a multivariate logistic regression analysis, IAH was an independent predictor of both ICU mortality (odds ratio (OR), 12.20; 95% confidence interval (CI), 1.92 to 77.31, p = 0.008) and need for RRT (OR, 6.78; 95% CI, 1.29 to 35.70, p = 0.02). Using receiver operating characteristic curves, IAP (area under the curve (AUC) = 0.74, p = 0.004), APP (AUC = 0.71, p = 0.01), Acute Physiology and Chronic Health Evaluation II score (AUC = 0.71, p = 0.02), but not MAP, differentiated survivors from nonsurvivors. CONCLUSIONS IAH is highly prevalent in cirrhotic patients with septic shock and is associated with increased ICU morbidity and mortality.

Abstract
OBJECTIVE To review the current knowledge of common comorbidities in the intensive care unit, including diabetes mellitus, chronic obstructive pulmonary disease, cancer, end-stage renal disease, end-stage liver disease, HIV infection, and obesity, with specific attention to epidemiology, contribution to diseases and outcomes, and the impact on treatments in these patients. DATA SOURCE Review of the relevant medical literature for specific common comorbidities in the critically ill. RESULTS Critically ill patients are admitted to the intensive care unit for various reasons, and often the admission diagnosis is accompanied by a chronic comorbidity. Chronic comorbid conditions commonly seen in critically ill patients may influence the decision to provide intensive care unit care, decisions regarding types and intensity of intensive care unit treatment options, and outcomes. The presence of comorbid conditions may predispose patients to specific complications or forms of organ dysfunction. The impact of specific comorbidities varies among critically ill medical, surgical, and other populations, and outcomes associated with certain comorbidities have changed over time. Specifically, outcomes for patients with cancer and HIV have improved, likely related to advances in therapy. Overall, the negative impact of chronic comorbidity on survival in critical illness may be primarily influenced by the degree of organ dysfunction or the cumulative severity of multiple comorbidities. CONCLUSION Chronic comorbid conditions are common in critically ill patients. Both the acute illness and the chronic conditions influence prognosis and optimal care delivery for these patients, particularly for adverse outcomes and complications influenced by comorbidities. Further work is needed to fully determine the individual and combined impact of chronic comorbidities on intensive care unit outcomes.

Abstract
OBJECTIVE Few studies have addressed the outcome of patients with cirrhosis requiring mechanical ventilation (MV). We aimed to investigate the short-term outcome of such patients. METHODS Retrospective review of data of 73 consecutive patients with cirrhosis requiring MV over a 2-year period (2006-2008). Data on patient's characteristics, reason for MV, the presence of other organ failure, and first day Acute Physiology Chronic Health Evaluation (APACHE) II, Sequential Organ Failure Assessment (SOFA), Child-Pugh (CP), and Model for End-Stage Liver Disease (MELD) scores were collected, with 30-day mortality being the primary outcome measure. RESULTS Observed mortality in ICU and at 30 days was 75.3% and 87.7%, respectively. Area under curve was 0.77 (95% CI, 0.65-0.86) for APACHE II, 0.94 (95% CI, 0.85-0.98) for SOFA, 0.83 (95% CI, 0.7-0.96) for CP, and 0.93 (95% CI, 0.85-0.98) for MELD (P = .096) in predicting 30-day mortality. By univariate analysis, indication for intubation (P = .001), need for vasopressor support (P = .002), the presence of renal failure (P < .03), and duration of MV (P < .001) were significantly associated with mortality. On multivariate analysis, only duration of MV (adjusted odds ratio 0.63, 95% CI: 0.42-0.95, P = .03) was the independent predictor of mortality with a majority of patients, 51/64 (79.7%), dying in the first 48 hours of intubation. CONCLUSIONS Patients with cirrhosis requiring MV have a dismal prognosis. Such patients and their families should be informed about the overall outcome to assist their decisions about life support and intensive care, outside the transplant setting. Prognostic scores, especially SOFA and MELD, may aid in determining which patients may benefit from aggressive therapy.

Abstract
PURPOSE OF REVIEW Liver cirrhosis and portal hypertension present with three unique pulmonary complications that are the subject of ongoing clinical research: hepatopulmonary syndrome, portopulmonary hypertension (POPH), and hepatic hydrothorax. The present article is based on a review of the current literature on how to manage these disorders, which are highly important to both anesthesiologists and intensive care physicians. RECENT FINDINGS Hepatopulmonary syndrome leads to progressive hypoxemia through diffuse vasodilatation of the pulmonary microcirculation. Liver transplantation, although associated with increased mortality, is the only viable treatment. POPH occurs when vascular remodeling triggers an increase in pulmonary artery pressure and resistance. The role of liver transplantation in POPH is controversial given the excessive mortality in patients with moderate to severe POPH. Medical treatment is able to decrease pulmonary artery pressures, though multicenter randomized controlled trials showing improved outcome are lacking to date. Ultrasound plays an increasingly important role in the diagnosis of all three conditions. SUMMARY Patients with end-stage liver disease are at risk for respiratory failure and hypoxemia and need to be screened for hepatopulmonary syndrome, POPH, and hepatic hydrothorax. Failure to timely recognize and adequately treat these complications of cirrhosis may have severe consequences.

Abstract
Liver cirrhosis is a common disease causing great public-health concern because of the frequent complications requiring hospital care. Acute liver failure is also prone to several complications but is rare. One of the main complications for both acute and chronic liver diseases is infection, which regularly causes decompensation of cirrhosis, possibly leading to organ failure and death. This review focuses on innate immune function in cirrhosis, acute-on-chronic liver failure and acute liver failure. The known defects of Kupffer cells, neutrophils and monocytes are discussed, together with the pathophysiological importance of gut permeability, portal hypertension and intrinsic cellular defects, and the role of endotoxin, albumin, lipoproteins and toll-like receptors. Based on these different pathomechanisms, the available information on therapeutic strategies is presented. Antibiotic and probiotic treatment, nutritional support, artificial liver support, and experimental strategies such as inhibition of toll-like receptors and use of albumin and colony-stimulating factors are highlighted.

Abstract
PURPOSE Data regarding outcome of patients with chronic liver disease with severe hepatic encephalopathy in intensive care unit are currently scarce. METHODS This study is a retrospective observational case series in a medical intensive care unit (ICU) in a university hospital from 1995 to 2005. Patients with hepatic encephalopathy (HE) (admitted with or developing) were identified. Clinical and laboratory parameters were analyzed to determinate predictors of ICU and 1-year mortality. RESULTS Seventy-one patients were included (53 male). Median Simplified Acute Physiology Score was 56 with Child-Pugh score 11 +/- 2. Seventy-six percent of patients were admitted with coma (Glasgow Coma Scale, 7.7 +/- 4). Eighty-two percent of patients required intubation, and 28% vasopressors. Thirty-five percent died during ICU stay. At 1 year, mortality was 54%. Univariate analysis identified arterial hypotension, mechanical ventilation, vasopressors at any time, acute renal failure, Simplified Acute Physiology Score, and sepsis associated with ICU mortality. In multivariate analysis, vasopressor use or acute renal failure was the main independent predictor of ICU death and 1-year mortality. Patients free of these risk factors, even requiring intubation, were identified as isolated HE, with lower mortality rates. CONCLUSION Predictors of outcome were similar to other groups of patients with liver disease admitted for other reasons. Intensive care unit mortality was lower than reported for other groups of patients with similar illness. Patients with severe HE admitted to ICU with no organ dysfunction other than mechanical ventilation had a better outcome and may require ICU admission.

Abstract
PURPOSE The study aimed to describe the clinical outcome of patients with liver cirrhosis admitted to intensive care unit (ICU) and to compare the performance of Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) in predicting mortality. METHODS In this prospective study of patients with cirrhosis admitted to the ICU, demographic data, APACHE II score, SOFA score, presence of acute renal failure (ARF), need for organ support, and mortality were collected. RESULTS The observed mortality in ICU and at 30 days among 104 patients was 42.3% (95% confidence interval [CI], 32.7%-52.0%) and 56.7% (95% CI, 47.0%-66.4%), respectively. Area under the receiver operating characteristic curve for first-day APACHE II in predicting 30-day mortality was 0.90 (95% CI, 0.83-0.96) and 0.93 (95% CI, 0.88-0.98) for SOFA score (P = .24). On multivariate analysis, ARF (adjusted odds ratio, 7.7; 95% CI, 1.09-54.64) and mechanical ventilation (adjusted odds ratio, 277.6; 95% CI, 12.83-6004.94) were significantly associated with mortality. CONCLUSIONS Presence of ARF and need for mechanical ventilation are associated with high mortality in patients with liver cirrhosis admitted to the ICU. Acute Physiology and Chronic Health Evaluation II and SOFA are good prognostic models in predicting 30-day mortality and do not differ in performance.

Abstract
BACKGROUND We aimed to examine the outcome of patients with decompensated alcoholic liver disease (ALD) admitted to a general intensive care unit (ICU). METHODS Retrospective observational cohort study of intensive care admissions over a 3 yr period was conducted. The study was set in an ICU in a UK university hospital with a tertiary liver referral unit. One hundred and ten admissions, involving 107 patients, with decompensated ALD were included. Intensive care, hospital, and 6 and 12 months mortality were recorded along with the outcome in diagnostic and organ system support subgroups. Intensive care, hospital, 6 month and 12 month mortality rates were 58, 71, 78 and 81%. RESULTS Hospital mortality in the sepsis/multiorgan failure group was 88%. Sixty-nine per cent of patients who were ventilated but required no other organ support survived to hospital discharge. However, the requirement for any other organ support, or a raised creatinine (>120 micromol litre(-1)) in the first 24 h, reduced the hospital survival to <15%. In those patients requiring acute renal replacement therapy, the hospital mortality was 94%. CONCLUSION Decompensated ALD requiring intensive care admission is associated with a high hospital mortality and consideration should be given to the futility of escalating organ support measures, particularly when renal replacement therapy is required.

Abstract
Despite improved survival after liver transplantation (OLTX) in HIV-positive individuals treated with highly active antiretroviral therapy (HAART), some transplant candidates do not survive to OLTX. To determine if pretransplant outcome is related to severity of liver disease and/or HIV infection, we prospectively evaluated 58 consecutive HIV-positive candidates seen at a single center from 1997-2002. Of the 58, 15 (25.9%) were transplanted, whereas 21 (36.2%) died before OLTX, a median one month of evaluation, with more than half of those (12 of 21, 57.1%) dying from infection. By contrast, of 1,359 HIV-negative candidates, 860 (63.3%) were transplanted, whereas 211 (15.5%) died before OLTX (P < 0.001). The cumulative survival following initial evaluation was significantly shorter among HIV-positive than HIV-negative candidates (880 vs. 1,427 days, P = 0.035, Breslow) but was not related to the initial pretransplant MELD score (16 vs. 15), INR (1.5 vs. 1.5), creatinine (1.3 vs. 1.3 mg/dL), or total bilirubin (6.6 vs. 5.7 mg/dL), respectively, all P > 0.05. Among untransplanted HIV-positive candidates, the 21 who died did not differ from the 22 surviving in initial MELD (15 vs. 13), CD4 (230 vs. 327/microL), HIV load (both < 400 copies/mL), HAART intolerance (10/21, 47.6% vs. 10/22, 45.4%), or HCV infection (16/21, 76.2% vs. 16/22, 72.3%), all P > 0.05. Further, the 21 did not differ from the 15 transplanted in pre-OLTX CD4, HIV load, or MELD score, all P > 0.05. In conclusion, pretransplant survival appears shorter in HIV-positive OLTX candidates and is unrelated to severity of liver or HIV disease. Further study is warranted to determine risk factors for poorer pretransplant outcomes.

Abstract
OBJECTIVE To determine outcome and mortality risk related to acute renal failure (ARF) in critically ill patients with cirrhosis. DESIGN AND SETTING A retrospective cohort analysis and two independent case-control analyses in a medical ICU. PATIENTS 41 and 32 patients who developed mild and severe ARF, respectively, matched (1:2 ratio) with cirrhotic patients without ARF during their ICU stay. MEASUREMENTS AND RESULTS Cirrhotic patients with ARF had higher MELD, APACHE II, and SOFA scores at baseline that those without ARF. They had more respiratory failure and cardiovascular failure during ICU stay, longer stay in ICU, and a greater crude hospital mortality rate (65% vs. 32%). Multivariate survival analysis identified ARF (hazard ratio, HR, 4.1), alcohol abuse or dependency, and severe sepsis or septic shock as independent predictors of death. In case-control studies both mild and severe ARF were independently associated with mortality (HR, 2.6, and 4.2, respectively). Cirrhotic patients with mild ARF patients had a higher risk of death than those without ARF (relative risk, RR, 2.0). Severe ARF was associated with an increase matched risk of death (RR 2.6), higher mortality of 51%, and higher risk-adjusted mortality rate (2.1 vs. 0.9). CONCLUSIONS ICU patients with liver cirrhosis still have a high crude mortality. In this specific population ARF is associated with an excess mortality, depending on the severity of renal dysfunction.

Abstract
BACKGROUND Acute renal failure (ARF) in the setting of end-stage liver disease has a dismal prognosis without liver transplantation. Renal replacement therapy (RRT) is a common bridge to liver transplant despite a paucity of supportive data. We investigated our single-center patient population to determine efficacy of RRT in liver transplant candidates with ARF. METHODS We identified 102 liver transplant candidates receiving RRT for ARF between April 30, 1999 and January 31, 2004. Patients that had initiated RRT intra- or postoperatively or received outpatient hemodialysis or peritoneal dialysis prior to admission were excluded. Survival to liver transplant, short-term mortality following liver transplant, and selected clinical characteristics were examined. RESULTS Of patients who received RRT, 35% survived to liver transplant or discharge. Mortality was 94% in patients not receiving a liver and was associated with a higher Acute Physiological and Chronic Health Evaluation (APACHE) II, lower mean arterial pressure, and the use of continuous renal replacement therapy (CRRT). Patients receiving CRRT had greater severity of illness than those on hemodialysis. The 1-year mortality of patients initiating RRT prior to liver transplant was 30% versus 9.7% for all other liver recipients (P < 0.0045). CONCLUSION RRT is justifiable for liver transplant candidates with ARF. Though mortality was high, a substantial percentage (31%) of patients survived to liver transplant. Postoperative mortality is increased compared with all other liver transplant recipients, but is acceptable considering the near-universal mortality without transplantation.

Abstract
STUDY OBJECTIVE To describe the clinical course, complications, and prognostic factors of morbidly obese patients admitted to the ICU compared to a control group of nonobese patients. DESIGN A retrospective study. SETTING Two university-affiliated hospitals. METHODS We reviewed the medical records of 117 morbidly obese patients (body mass index >/= 40 kg/m(2)) admitted to the medical ICU between January 1994 and June 2000. Data collected included demographic information, comorbid condition, APACHE (acute physiology and chronic health evaluation) II score, invasive procedures, organ failure, and in-hospital mortality. RESULTS Obstructive airway disease, pneumonia, and sepsis were the main reasons for admission to the ICU in the morbidly obese group. Sixty-one percent of the morbidly obese patients and 46% of the nonobese group required mechanical ventilation (p = 0.02). The mean lengths of mechanical ventilation and ICU stay were significantly longer for the morbidly obese group (7.7 +/- 9.6 days and 9.3 +/- 10.5 days vs 4.6 +/- 7.1 days and 5.8 +/- 8.2 days, respectively; p < 0.001). APACHE II scores were not significantly different in the two groups (19.1 +/- 7.6 and 20.6 +/- 12.2; p = 0.6). Overall mortality was 30% for the morbidly obese patients and 17% for the nonobese group (p = 0.019). By multivariate analysis, multiorgan failure (odds ratio [OR], 4.6; 95% confidence interval [CI], 2.1 to 16.6), PaO(2)/fraction of inspired oxygen < 200 for > 48 h (OR, 2.3; 95% CI, 1.2 to 7.8), and depressed left ventricular ejection fraction < 40% (OR, 1.4; 95% CI, 1.03 to 13.8) were independently associated with ICU mortality in the morbidly obese group. CONCLUSION We conclude that critically ill morbidly obese patients are at increased risk of morbidity and mortality compared to the nonobese patients.
