Certainly, some patients with higher grades of ACLF (3 or more organ failures) may be considered for palliative care alone. Fulminant and subfulminant liver failure: definitions and causes. Gastroenterology 2016;150:157989.e2. In a meta-analysis, rifaximin was superior to no antibiotics, but equivalent to an oral quinolone for SBP prophylaxis, although most studies included were small, not randomized, or did not allow rifaximin for treatment of HE (110). First-line antibiotic therapy should be determined by the etiology and severity of the infection, how it was acquired (community-acquired, healthcare-associated, or nosocomial), and local resistance patterns. Management of the ACLF patient is best accomplished by a multidisciplinary team approach including expertise in critical care and transplant hepatology. Terlipressin plus albumin for the treatment of type 1 hepatorenal syndrome. 51. Bajaj JS, Acharya C, Fagan A, et al. Although galactomannan index and 1,3 D Glucan are an adjunct for fungal infections and have high sensitivity, they have limited specificity, have only been studied in small series, and therefore better modalities for rapid fungal infection diagnosis are required to prevent ACLF (106). Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. PLoS One 2015;10:e0135625. Hepatology 2016;63:201931. Liver Transpl 2020;26(12):165861. Clin Gastroenterol Hepatol 2011;9:72738. 1970;3:282-98. Choudhury A, Jindal A, Maiwall R, et al. To assess volume status, dynamic measurements in response to fluid boluses are recommended. Typically, a history of heavy alcohol use is present for greater than 5 years, but heavy alcohol use for a duration of as little as 6 months may cause AAH (126). 4. 111. News in pathophysiology, definition and classification of hepatorenal syndrome: A step beyond the International Club of Ascites (ICA) consensus document. Estimated incidence in Asian countries is approximately 10%, and that in the United States is approximately 7%. Gustot T, Fernandez J, Garcia E, et al. In the absence of data, adherence to published guidelines on nutritional support in critically ill patients with cirrhosis is recommended (165,166). It should be noted that patients with CKD with a higher baseline sCr have a more severe course of AKI (38). Vilstrup H, Amodio P, Bajaj J, et al. Therefore, among ICU patients requiring mechanical ventilation, a strategy of stress ulcer prophylaxis with PPI use is marginally superior to H2 receptor blockers (61). 158. Clin Gastroenterol Hepatol 2018;16:1792800.e3. Key concepts are statements that the GRADE process has not been applied to and often include definitions and epidemiological statements rather than diagnostic or management recommendations. 86. Singh S, Murad MH, Chandar AK, et al. 193. In multivariable analysis, only the Lille model and the MELD score were independently associated with 6-month survival. Immune dysfunction and infections in patients with cirrhosis. Patients with cirrhosis of liver operated for non-transplant surgery: A retrospective analysis. 82. Diagnosis and treatment of alcohol-associated liver diseases: 2019 practice guidance from the American Association for the Study of Liver Diseases. The prognostic role of hepatic venous pressure gradient in cirrhotic patients undergoing elective extrahepatic surgery. It is critical that effective broad-spectrum antibiotics be administered within 1 hour of ICU admission in patients with cirrhosis because every hour delay in administration of antibiotics is associated with almost doubling in mortality (162). 118. Sanyal AJ, Boyer TD, Frederick RT, et al. http://www.ncbi.nlm.nih.gov/pubmed/3082735?tool=bestpractice.com In contrast with healthy subjects, patients with cirrhosis have a systemic inflammatory milieu that is exacerbated by gut microbial dysbiosis. In the absence of contraindications, such as recent bleeding and significant thrombocytopenia, hospitalized cirrhotic patients should receive pharmacologic VTE prophylaxis. There were more patients in the albumin arm who developed pulmonary edema and respiratory infections (175,176). Statins have been shown to decrease the rate of hepatic fibrosis, hepatic decompensation, and mortality in patients with cirrhosis; every year of statin exposure cumulatively and independently decreased mortality in patients with CTP-A and -B cirrhosis (119121). More rapid completion of a 3-hour sepsis-care bundle and rapid administration of antibiotics is associated with lower risk-adjusted in-hospital mortality in patients with sepsis (91). JAMA 2016;315:80110. Adverse events in the treatment arm included fever, herpes zoster reactivation, nausea, and rash. J Hepatol 2004;40:24754. An MAP goal of 60 mm Hg in patients with cirrhosis, rather than 65 mm Hg, is recommended without specific targets for ventricular filling pressure, volume, lactate, or central venous oxygen saturation (ScvO2) (31). Liver Int 2016;36:38694. J Hepatol 2014;60:27581. PMID: 36157143 PMCID: PMC9499845 (available on 2023-09-01) DOI: 10.1016/j.jceh.2021.12.010 Boyer TD, Sanyal AJ, Wong F, et al.

Chen Y, Guo J, Qian G, et al. Immunosuppression in acutely decompensated cirrhosis is mediated by prostaglandin E2. Wong F, Nadim MK, Kellum JA, et al. In the STOPAH study, which was a multicenter, randomized, double-blind trial with a 2-by-2 factorial design conducted in 65 hospitals across the United Kingdom, pentoxifylline did not improve survival in patients with AAH (129). Moreover, none of the definitions requires the potential for reversibility of liver failure, which is the hallmark of an acute-on-chronic condition as opposed to chronic end-stage disease. Four principles to approach patients with cirrhosis and altered mentation; Adapted from Acharya et al. In hospitalized patients with decompensated cirrhosis, the presence of a nosocomial infection is associated with increased risk of ACLF development and mortality. Use of novel polymerase chain reaction technology can shorten the time to diagnosis of pathogens and resistance patterns, thereby shortening the time to diagnosis and antibiotic de-escalation (99). In patients with cirrhosis in need of primary SBP prophylaxis, we suggest daily prophylactic antibiotics, although no one specific regimen is superior to another, to prevent SBP (low quality, conditional recommendation). Therefore, monitoring volume status by respiratory variations of the inferior vena cava may be inaccurate. Therefore, surgery is usually not recommended unless the benefits outweigh the risks. Rating the quality of evidence. The factors that predict mortality after the development of ACLF include liver surgery, alkaline phosphatase with a cutoff of 164 IU/L, and an MELD score with a cutoff of 10. Once again, there was a significant reduction in serum bilirubin with Prometheus use, most likely from the filtering function of the Prometheus system, but this did not result in improvement in survival. In a multicenter French and Belgian study, the combination of prednisone and pentoxifylline has not been found to be superior to prednisone alone (128). Gastroenterology 2019;156:1693706.e12. J Hepatol 2019;70:31927. MDR pathogens have been increasing in prevalence and are reported in 22%38% of infections in hospitalized patients with cirrhosis (100,101). Maintaining a daily caloric intake of 35- to 40-cal/kg body weight/day that includes a daily protein intake of 1.2- to 2.0-g/kg body weight/day is recommended (167). Hepatology 2018;68(4):162132. Various artificial and bioartificial extracorporeal liver support systems have been tried as a treatment for ACLF (180,181). CXCL9 is a prognostic marker in patients with liver cirrhosis receiving transjugular intrahepatic portosystemic shunt. 147. 105. A randomized trial of albumin infusions in hospitalized patients with cirrhosis. Most patients developed grade 1 ACLF, with the most common organ failure being renal failure defined as an sCr of >2.0 mg/dL. 149. AKI, acute kidney injury; HRS, hepatorenal syndrome. IV albumin is not recommended to prevent organ failures in patients with cirrhosis who have infections other than SBP. Comparison of dopamine and norepinephrine in the treatment of shock. Depending on these factors, patients with identical ACLF and MELD scores may range from considering transplant for one patient but comfort-focused measures only for another. Hepatology 2019;70:41828. 133. Treatment options for HRS-AKI include pharmacotherapy and liver transplantation with or without intervening RRT in the appropriate patients.

An overview of managing ACLF in critical care is shown in Figure 5. Please enable scripts and reload this page. Patients with cirrhosis who acquire an infection may not have typical symptoms of infection. An additional reason for current disagreements between the various definitions is the presence of diagnostic or prognostic criteria vs defining criteria (ascites and jaundice in the Asian Pacific definition and organ failure in CLIF and NACSELD definitions) (11). In ventilated patients with cirrhosis, we suggest against prophylactic antibiotics to reduce mortality or duration of mechanical ventilation (very low quality, conditional recommendation). Patients with CKD can also develop an acute deterioration in renal function with prerenal azotemia or with the development of a bacterial infection. Appropriate and timely antimicrobial therapy in cirrhotic patients with spontaneous bacterial peritonitis-associated septic shock: A retrospective cohort study. The varying definitions that focused on established organ failure have reduced generalizability and potential for prevention of ACLF in different settings. Piano S, Schmidt HH, Ariza X, et al. Aliment Pharmacol Ther 2019;49:151827. Because patients in the ICU are under the care of intensive care specialists and not hepatologists, specific recommendations regarding threshold for ventilation, pressor support, and endotracheal intubation will not be made in this guideline. 152. This study shows the prevalence of . The patients who developed ACLF were older and had higher baseline CTP and MELD scores. 106. Long-term use of antibiotics and proton pump inhibitors predict development of infections in patients with cirrhosis. Routine use of sedatives is discouraged in patients with grade 34 encephalopathy and may be associated with delay in extubating. Your tummy (abdomen) may become swollen because of a build-up of fluid (ascites). Reverter E, Cirera I, Albillos A, et al. 78. In fact, recent data have clearly shown that INR, although strongly linked with liver function in the absence of vitamin K deficiency, does not measure coagulation in patients with cirrhosis (72). Gastroenterology 2008;134:13608. Prognostic markers that predict ACLF outcome should be separate from diagnostic markers that confirm the presence of ACLF. Terlipressin plus albumin is more effective than albumin alone in improving renal function in patients with cirrhosis and hepatorenal syndrome type 1. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation process. J Hepatol 2019;72(4):688701. In patients with cirrhosis, we suggest against the use of biomarkers to predict the development of renal failure (very low quality, conditional recommendation). Community-acquired infections are diagnosed <48 hours from admission in the absence of healthcare exposure in the past 90 days. C-reactive protein and bacterial infection in cirrhosis.

The most important of these include producing bile, storing glycogen, and removing toxins from the bloodstream. O'Leary JG, Bajaj JS, Tandon P, et al. In patients with cirrhosis and ACLF, we suggest against the use of granulocyte colony-stimulating factor (G-CSF) to improve mortality (very low evidence, conditional recommendation). Combining data from liver disease scoring systems better predicts outcomes of patients with alcoholic hepatitis. 1993 Jul 31;342(8866):273-5. http://www.ncbi.nlm.nih.gov/pubmed/8101303?tool=bestpractice.com. In patients without cirrhosis, septic shock is identified by the need for vasopressor support to maintain an MAP of 65 mm Hg and serum lactate level 2 mmol/L (>18 mg/dL) in the absence of hypovolemia (160). Hemodynamic studies in acute-on-chronic liver failure. Antibiotic prophylaxis in cirrhosis: Good and bad. Gigascience 2016;5:32. 190. Bajaj JS, Ananthakrishnan AN, Hafeezullah M, et al. When these observations were extended into a multicenter study, gut microbial composition on admission predicted outcomes (20). 68. Crabb DW, Im GY, Szabo G, et al. Similar precipitating events were noted in a study from Asia (124). J Clin Exp Hepatol 2020;10:20110. ACG clinical guideline: Alcoholic liver disease. Because serum C-reactive protein, procalcitonin, and bacterial DNA levels are often elevated in patients with cirrhosis, they are not diagnostic of infection, although persistently high levels correlate with mortality (9295). Altered profile of human gut microbiome is associated with cirrhosis and its complications. Am J Gastroenterol 2019;114:92937. For example, PPIs are needed to heal gastrointestinal ulcers and erosive esophagitis and treat gastroesophageal reflux not responsive to H2 blockers (115). CKD can be either functional, observed mostly in patients with refractory ascites and would be equivalent to what used to be known as HRS type 2, or related to structural renal diseases such as diabetic nephropathy. 197. Infections complicating cirrhosis. Karvellas CJ, Subramanian RM. It has been shown that damage-associated molecular patterns released from necrotic hepatocytes and breakdown of extracellular matrix can initiate an intense sterile inflammatory response. Gastroenterology 2018;155:45868.e8. Nonsurgical interventions can also precipitate ACLF, but the exact incidence is unknown. Although no pathogen was identified in nearly one-quarter of patients, Gram-positive bacteria were more frequently identified (33%) than Gram-negative bacteria (27%) as the source of infection. Berres ML, Asmacher S, Lehmann J, et al. Serum and ascitic fluid bacterial DNA: A new independent prognostic factor in noninfected patients with cirrhosis. Patients with underlying liver disease can develop ACLF if they contract any of the known viral hepatitides. Acute-on-chronic liver failure: Consensus recommendations of the Asian Pacific association for the study of the liver (APASL): An update. Because PPIs impair the oxidative burst of neutrophils, they further impair immune function in patients with cirrhosis. Am J Gastroenterol 2018;113:1339. 65. Acute liver failure, also known as fulminant hepatic failure, can cause serious complications, including bleeding and increased pressure in the brain. The severity of organ failure may be assessed by the EASL-CLIF sequential organ failure assessment score or NACSELD organ failures score (Tables 3 and 4) (5). Introduction-GRADE evidence profiles and summary of findings tables. Outcomes in patients with cirrhosis on primary compared to secondary prophylaxis for spontaneous bacterial peritonitis. Reddy KR, O'Leary JG, Kamath PS, et al. Bajaj JS, O'Leary JG, Lai JC, et al. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) process was used to assess the quality of evidence for each statement (1). J Hepatol 2019;70:17293. The use of albumin in addition to antibiotics is recommended in patients with SBP to prevent HRS-AKI and subsequent organ failures but not recommended in non-SBP infections (54,55). However, survival beyond 6 months was again only associated with abstinence from alcohol (134). Medicine (Baltimore) 2018;97:e0431. Another meta-analysis of 11 studies including 2,111 patients showed that corticosteroid use reduced the risk of death within 28 days of treatment as compared with pentoxifylline, but not beyond that period (132). Because alcohol consumption may be prevalent among patients with hepatitis B infection, such patients can have submassive necrosis. Alcohol and chronic viral hepatitis are the most common underlying liver diseases. AAH is a major cause of ACLF worldwide. Malnutrition, frailty, and sarcopenia in patients with cirrhosis: 2021 practice guidance by the American Association for the Study of Liver Diseases. Single-center studies have identified gut and circulating microbial composition that independently predict the development of ACLF, albeit defined differently (16,17,19). As cirrhosis and portal hypertension worsens, the MAP tends to decrease, and consistent data have shown that a high MAP is protective from ACLF (6,68). Background: Acute on chronic liver disease is determined by the acute deterioration of liver function over a short period of time. Kribben A, Gerken G, Haag S, et al. 28. Until the time when the pathogenesis of ACLF is clearly understood, diagnosis of ACLF should rely on a set of symptoms, signs, and laboratory tests. JAMA 2013;310:103341. However, neither the risk of ACLF nor its outcomes have specifically been evaluated in patients with cirrhotic cardiomyopathy. In other patients, pharmacologic prophylaxis with LMWH is preferred, but systematic studies comparing prophylactic agents and strategies are lacking (83). Other measures include (i) judicious use of laxatives and diuretics; (ii) albumin infusions with large-volume paracentesis; (iii) prompt treatment of gastrointestinal bleeds and use of antibiotic prophylaxis in patients with established gastrointestinal bleeds; (iv) avoidance of nephrotoxic drugs or radiographic dye; and (v) primary prophylaxis against SBP in high-risk individuals and secondary prophylaxis for patients after the first episode of SBP. The patient's blood is first passed through a specialized membrane, and the blood cells and large protein molecules are separated from the plasma and molecules smaller than 250 kD. A meta-analysis of 4 RCTs and 6 nonrandomized clinical trials (conducted in China, Iran, and Switzerland) evaluating the effect of stem cell therapy on patients with ACLF demonstrated overall decrease in total bilirubin, ALT, albumin, and MELD score at 12 months of therapy but not in INR (191). Hepatology 2013;57:244857. 20. Patients need to be closely monitored in the postprocedure period for the development of ACLF. 2008 Apr;47(4):1401-15. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3381946, http://www.ncbi.nlm.nih.gov/pubmed/18318440?tool=bestpractice.com, Acute-on-chronic liver failure clinical guidelines, AASLD practice guidance on drug, herbal and dietary supplement-induced liver injury. Vaccinate patients with chronic liver disease against hepatitis A and hepatitis B if they are not already immune. Fungal pathogens are a particularly important source of infection in patients with ACLF, most of which are nosocomial (104). Effect of the clinical course of acute-on-chronic liver failure prior to liver transplantation on post-transplant survival. 15. Aliment Pharmacol Ther 2017;46:102936.
