The Mayo Clinic calculator for postsurgical risks of mortality has been in use for more than a decade and has been validated in other study populations (148,150,151) and can be found here (https://www.mayoclinic.org/medical-professionals/transplant-medicine/calculators/post-operative-mortality-risk-in-patients-with-cirrhosis/itt-20434721). 59. Crabb DW, Bataller R, Chalasani NP, et al. Fernandez J, Prado V, Trebicka J, et al. Intensive care management of the ACLF patient involves early goal-directed therapy, intravascular volume resuscitation, broad-spectrum antibiotic administration within 1 hour of presentation, monitoring of tissue oxygenation, support of failing organs including consideration of artificial liver support, and LT in selected patients. 131. Most patients with ACLF in the CLIF consortium study either had alcohol use, AAH, or infection as the precipitating event (36). Am J Transplant 2016;16:75866. Most patients developed grade 1 ACLF, with the most common organ failure being renal failure defined as an sCr of >2.0 mg/dL. In patients with severe alcohol-associated hepatitis (Maddrey discriminant function [MDF] 32; MELD score > 20) in the absence of contraindications, we recommend the use of prednisolone or prednisone (40 mg/d) orally to improve 28-day mortality (moderate quality, strong recommendation). 128. Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. The impact of albumin use on resolution of hyponatremia in hospitalized patients with cirrhosis. http://www.ncbi.nlm.nih.gov/pubmed/4908702?tool=bestpractice.com Hepatitis B flares seem to be particularly common in patients with underlying chronic liver disease, especially in those with decompensated cirrhosis. A hepatitis B flare often occurs in patients either spontaneously or on abrupt stopping of their antiviral medications. Claria J, Stauber RE, Coenraad MJ, et al. Although most data document the utility of daily norfloxacin, in areas where this is not available, daily ciprofloxacin or trimethoprim-sulfamethoxazole may be used. Incidence, risk factors, and outcomes of transition of acute kidney injury to chronic kidney disease in cirrhosis: A prospective cohort study. Bajaj JS, O'Leary JG, Wong F, et al. Creatinine change on vasoconstrictors as mortality surrogate in hepatorenal syndrome: Systematic review & meta-analysis. Systemic inflammatory response exacerbates the neuropsychological effects of induced hyperammonemia in cirrhosis. In the NACSELD experience, nosocomial infections were more likely caused by vancomycin-resistant Enterococcus, C. difficile, or fungal species than other infections (103). EASL-CLIF and NACSELD definitions of ACLF require the presence of organ failure. Gut 2012;61:121925. Norepinephrine is the vasopressor of choice in patients with ACLF. Critical care management strategies and LT potential listing should be balanced with futility considerations in those with a poor prognosis. Int J Infect Dis 2014;23:6974. Long-term albumin administration in decompensated cirrhosis (ANSWER): An open-label randomised trial. The management of fulminant hepatic failure. Invasive fungal infections amongst patients with acute-on-chronic liver failure at high risk for fungal infections. Although they sound attractive, the technology is complex, and it requires a critical cell mass. Development and validation of a prognostic score to predict mortality in patients with acute-on-chronic liver failure. Am J Gastroenterol 2020;115(12):202635. Careful large-volume paracentesis is recommended in patients with tense ascites (161). Hepatology 2017;66:127585. In patients with cirrhosis and infections other than SBP, we recommend against albumin to improve renal function or mortality (high quality, strong recommendation). Liver Transpl 2019;25:5719. Singal AK, Bataller R, Ahn J, et al. Acute-on-chronic liver failure (ACLF) is a recently recognised and defined syndrome seen in patients with liver cirrhosis and carries a high short-term mortality in excess of 15% at 28 days. Acute-on-chronic liver failure (ACLF) is a complication that can occur in patients with liver cirrhosis and is characterized by acute deterioration of liver function, organ failure, and a high risk of short-term mortality [1,2,3].Although the variety of definitions makes it difficult to predict the exact proportion of cirrhotic patients who meet the criteria for ACLF, it is estimated that 24 . [3]Bernuau J, Rueff B, Benhamou JP. In patients with cirrhosis and ACLF, we suggest against INR as a means to measure coagulation risk (very low quality, conditional recommendation). Am J Gastroenterol 2018;113:117786. Acute-on-chronic liver failure: Getting ready for prime-time. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) process was used to assess the quality of evidence for each statement (1). 142. An HVPG of >16 mm Hg was associated with an increased risk of mortality at 1 year (hazard ratio of > 2.5), and for an HVPG of 20 mm Hg, the hazard ratio for death at 1 year was 5.67. Current studies have used protocols that provide vasoconstrictor treatment for up to 14 days under which treatment could be stopped earlier if there is no response to treatment on day 4 (less than 25% reduction in sCr with vasoconstrictor) (45). Prog Liver Dis. Log in or subscribe to access all of BMJ Best Practice. Thrombelastography-guided blood product use before invasive procedures in cirrhosis with severe coagulopathy: A randomized, controlled trial. 34. 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. Runyon BA, AASLD Practice Guidelines Committee. Because infections are the number one cause of ACLF in North America and Europe, it is imperative to decrease the rate of infections in our patients with cirrhosis. Eighty-four of the 1,666 patients with cirrhosis had decompensation related to CAM use; of these, 30 developed ACLF (141). However, neither the risk of ACLF nor its outcomes have specifically been evaluated in patients with cirrhotic cardiomyopathy. When DILI causes liver injury, it usually causes acute liver failure. Sung CM, Lin YF, Chen KF, et al. Comparative effectiveness of pharmacological interventions for severe alcoholic hepatitis: A systematic review and network meta-analysis. Statin use and risk of cirrhosis and related complications in patients with chronic liver diseases: A systematic review and meta-analysis. In patients who do not have ACLF on admission, there are few studies that address clinical characteristics and biomarkers that predict its development. Two forms are recognised, acute and chronic (cirrhosis). Hepatology 2019;69:227183. However, when mucosal bleeding does occur or invasive procedures are required in the presence of an abnormal TEG study, cryoprecipitate or prothrombin complex concentrate are the preferred low-volume alternatives to raise the fibrinogen level (74,76,78). 33. may email you for journal alerts and information, but is committed Chemokine (C-X-C motif) ligand 11 levels predict survival in cirrhotic patients with transjugular intrahepatic portosystemic shunt. 49. 163. One study showed not only a decreased rate of portal vein thrombosis but also a lower rate of decompensation in patients randomized to LMWH compared with placebo. 38. Because patients have elevated intra-abdominal pressure because of ascites, monitoring of central venous pressure may be inaccurate. Bernuau J, Rueff B, Benhamou JP. 137. Bajaj JS, Reddy KR, Tandon P, et al. Hepatol Commun 2019;3:100112. Clin Gastroenterol Hepatol 2015;13:7539.e12. Of note, primary prophylaxis was studied and recommended in an era when transplant occurred at a lower MELD in patients with progressive liver disease from hepatitis C virus, and now that patients wait longer for transplant, we may need to re-evaluate the indications and drugs used for primary SBP prophylaxis. 139. A recent survey of US-based transplant clinicians showed that there is no consensus in providing additional MELD points or extending live donor transplant to patients with ACLF (198). 193. 116. Cell Mol Gastroenterol Hepatol 2019;8:30118.e2. The authors have also highlighted key concept statements that were not included in the GRADE assessment. In patients with cirrhosis and spontaneous bacterial peritonitis (SBP), we recommend albumin in addition to antibiotics to prevent AKI and subsequent organ failures (high quality, strong recommendation). avoid? In one randomized controlled trial (RCT), carvedilol improved 28-day but not 90-day transplant-free survival in admitted patients with ACLF compared with placebo (117). It seems that patients with more severe liver dysfunction are at higher risk of the development of ACLF with endoscopic retrograde cholangiopancreatography (ERCP). Therefore, it is essential to rule out infection in all patients with ACLF, but the level of suspicion for infection in patients with ACLF and hypocoagulability should be even higher. Arvaniti V, D'Amico G, Fede G, et al. Liver Int 2018;38(Suppl 1):12633. The aetiology and the interval from onset of jaundice to the development of encephalopathy have a significant impact on prognosis. Bajaj JS, Heuman DM, Hylemon PB, et al. J Hepatol 2020;72:4818. 9. Five-percent albumin is often used for rapid volume resuscitation, whereas for more sustained volume expansion, we recommend 25% albumin. 181. 43. Post-traumatic stress in the intensive care unit. Patients with ACLF are best managed in the intensive care unit (ICU), and some may benefit from early liver transplantation. Nat Rev Dis Primers 2018;4:23. Infections may progress to septic shock where almost 65% of patients will die. NAFLD is the leading cause of cirrhosis during pregnancy and of liver transplantation in females, and recent research suggests that it is associated with adverse pregnancy outcomes, such as hypertensive disorders of pregnancy and gestational diabetes. In patients with cirrhosis without ACLF, a rebalancing in coagulation occurs; however, in specific circumstances, hypercoagulability can be found (81,82). Hepatorenal syndrome. The article (CLD1189/CLD-21-0084.R1) "Surgical considerations regarding transplantation for the patient with acute on chronic liver failure" was published outside of this series issue "The Role of Liver Transplantation in Acute on Chronic Liver Failure". Am J Gastroenterol 2019;114:8997. 11. In patients with cirrhosis and ACLF who continue to require mechanical ventilation because of adult respiratory distress syndrome or brain-related conditions despite optimal therapy, we suggest against listing for LT to improve mortality (very low evidence, conditional recommendation). Sanyal AJ, Boyer TD, Frederick RT, et al. Am J Gastroenterol 2020;115(7):9891002. Embolization of large spontaneous portosystemic shunts for refractory hepatic encephalopathy: A multicenter survey on safety and efficacy. Liver Transpl 2021. Acute renal dysfunction is now renamed as AKI and is defined as acute increase of sCr by 0.3 mg/dL in <48 hours or a 50% increase in sCr from a stable baseline sCr with the increase presumably to have occurred in the past 7 days (Table 5) (30). Because of the reduction in the quantity and impaired quality of albumin in patients with cirrhosis, which worsens with advancing disease, albumin could have potential uses in other indications as well (171). In addition, the alcohol use disorder needs to be treated. Although steroids are associated with improved resolution in shock, there is no long-term survival benefit (164). Hepatology 2020;71:100922. Therefore, every attempt should be made to discuss goals of care with the patient before the onset of encephalopathy whenever possible. Diseases may be classified according to pathophysiology, or based on the organ involved, although characterizing the disease is often difficult because many diseases affect more than one organ. In a recently published single-center study that assessed the outcomes of cirrhotic patients who underwent surgery, of the 330 patients, 81 (24.5%) developed ACLF by EASL-CLIF criteria within 28 days of surgery (152). Hepatology 2020;73(1):20418. J Hepatol 2019;71:94250. Medicine (Baltimore) 2018;97:e0431. Liver Int 2016;36:38694. Going from evidence to recommendation-determinants of a recommendation's direction and strength.

The development and outcome of acute-on-chronic liver failure after surgical interventions. Terlipressin is not currently US Food and Drug Administrationapproved but is expected to be approved in the near future. In patients with cirrhosis with a history of SBP, we suggest use of antibiotics for secondary SBP prophylaxis to prevent recurrent SBP (low quality, conditional recommendation). The RCT assessing the use of MARS for ACLF (182) reported that MARS was able to decrease sCr and serum bilirubin (a molecule removal function of the dialysis system without necessarily improving renal or liver function) and reduce HE to a greater extent than the control group. Liver biopsy is required to make a diagnosis of definite AAH, although patients may be entered into clinical protocols with a diagnosis of probable AAH (history of heavy alcohol use, typical clinical and laboratory presentation described above, and absence of confounding factors that may explain the clinical picture). The role of ACLF prediction, precipitating factors, individual organ failures, management strategies, and impact on liver transplantation or end-of-life care is evolving. The quality of evidence is expressed as high (we are confident in the effect estimate to support a particular recommendation), moderate, low, or very low (we have very little confidence in the effect estimate to support a particular recommendation) based on the risk of bias of the studies, evidence of publication bias, heterogeneity among studies, directness of the evidence, and precision of the estimate of effect (2). In patients with end-stage liver disease admitted to the hospital, we suggest early goals of care discussion and if appropriate, referral to palliative care to improve resource utilization (very low evidence, conditional recommendation). Bajaj JS, Reddy KR, O'Leary JG, et al. Hepatology. doi: 10.1002/lt.26311. Predictors of poor outcomes after LT have included mechanical ventilation, higher donor risk index, older age, and LT > 30 days after listing (200). 96. Acute-on-Chronic Liver Failure | NEJM 176. Guidelines for combined liver and kidney transplants are available, but the effectiveness of current policies regarding simultaneous liver kidney transplant needs to be evaluated. 161. Acute liver failure in adults: Etiology, clinical - UpToDate 150. In patients who are hemodynamically unstable, until proven otherwise, an elevation in serum lactate suggests tissue hypoxia. Adverse events and acute chronic liver failure in patients with cirrhosis undergoing endoscopic retrograde cholangiopancreatography: A multicenter matched-cohort study. 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.
