acute on chronic liver failure

Comparison and analysis of delirium induced by histamine h(2) receptor antagonists and proton pump inhibitors in cancer patients. 113. 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. Clin Gastroenterol Hepatol 2017;15:152130.e8. Time to treatment and mortality during mandated emergency care for sepsis. 42. Terlipressin plus albumin is more effective than albumin alone in improving renal function in patients with cirrhosis and hepatorenal syndrome type 1. Another retrospective study of 127 US Veterans Administration centers found that MELD-Na did not correlate with ACLF severity (195). Administration of albumin solution increases serum levels of albumin in patients with chronic liver failure in a single-arm feasibility trial. 124. 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. In patients who are hemodynamically unstable, until proven otherwise, an elevation in serum lactate suggests tissue hypoxia. Specifically, systolic dysfunction is defined as left ventricular ejection fraction of 50% or an absolute global longitudinal strain of <18% or >22%. In hospitalized patients with cirrhosis and HRS-AKI without high grade of ACLF or disease, we suggest terlipressin (moderate quality, conditional recommendation) or norepinephrine (low quality, conditional recommendation) to improve renal function. 8. Outlines of the 3 major ACLF definitions. Healthcare-associated and especially nosocomial infections are more likely to be MDR. J Clin Gastroenterol 2020;54:25562. 189. Thromb Haemost 2017;117:13948. Effect of intravenous albumin on renal impairment and mortality in patients with cirrhosis and spontaneous bacterial peritonitis. What role should acute-on-chronic liver failure play in liver transplant prioritization? Lee WM, Squires RH Jr, Nyberg SL, et al. 74. 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. 164. 154.

Liver transplantation in the most severely ill cirrhotic patients: A multicenter study in acute-on-chronic liver failure grade 3. In highly selected patients with severe AAH not responding to optimal medical therapy and supportive measures, LT may be considered (135,136). G-CSF has been studied to reduce mortality in patients with ACLF in several randomized clinical trials (186189). Identification of specific diagnostic signs or symptoms, or a confirmatory test is key to further defining the entity such that the diagnosis can be made early and will warrant management changes. 21. Liver Transpl 2020;26:22737. 144. Sung CM, Lin YF, Chen KF, et al. Hassanein TI, Schade RR, Hepburn IS. 160. Variability in definitions of organ failure. CT, computed tomography; DVT, deep venous thrombosis; GI, gastrointestinal; HPS, hepatopulmonary syndrome; MAP, mean arterial blood pressure; PRBC, packed red blood cells. In patients with cirrhosis and ACLF, we suggest against INR as a means to measure coagulation risk (very low quality, conditional recommendation). Suggested algorithm for the critical care management of acute-on-chronic liver failure in cirrhosis. Although they sound attractive, the technology is complex, and it requires a critical cell mass. 158. Vasoconstrictors are used to improve splanchnic and systemic hemodynamics, so to improve renal perfusion and function. Gastroenterology 2016;150:78590. 98. Once ACLF develops, 37% of patients eventually improved, 49% remained stable, whereas 14% deteriorated. AIDS 2017;31:87584. [1]Trey C, Davidson CS. 181. 81. Hepatology 2013;57:115362. Am J Gastroenterol 2017;112:1495505. A retrospective analysis of the United Network for Organ Sharing database showed that EASL-CLIF ACLF-3 patients did well after transplant, whereas those on mechanical ventilation did not. Bajaj JS, O'Leary JG, Reddy KR, et al. Midodrine and albumin for prevention of complications in patients with cirrhosis awaiting liver transplantation. However, one must be concerned about dose-related hepatotoxicity of statins in patients with ACLF, given the recent randomized study of patients with CTP-B and -C cirrhosis that showed an increase in alanine aminotransferase (ALT) in patients randomized to 40 mg per day of simvastatin that was not seen in patients randomized to 20 mg per day or placebo (123). Survival in infection-related acute-on-chronic liver failure is defined by extra-hepatic organ failures. Acute renal failure is defined by the ICA as stage 2 AKI. 72. Wong F, Leung W, Al Beshir M, et al. 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. Treatment with carvedilol improves survival of patients with acute-on-chronic liver failure: A randomized controlled trial. AGA clinical practice update: Coagulation in cirrhosis. Aliment Pharmacol Ther 2019;49:151827. The choice of antibiotics depends on local susceptibility patterns. Diagnosis and treatment of alcohol-associated liver diseases: 2019 practice guidance from the American Association for the Study of Liver Diseases. Prevention of major precipitating factors such as infections and alcohol is critical in improving the prognosis of individual organ failures (brain, circulatory, renal, respiratory, and coagulation), and judicious use of antibiotics and antifungal medications is required. Because PPIs impair the oxidative burst of neutrophils, they further impair immune function in patients with cirrhosis. Seymour CW, Gesten F, Prescott HC, et al. High risk of delisting or death in liver transplant candidates following infections: Results from the North American Consortium for the Study of End-Stage Liver Disease. We evaluated the prognosis of patients with alcohol-related ACLF in our cohort and explored the prognostic factors. Acute-on-chronic liver failure: Consensus recommendations of the Asian Pacific association for the study of the liver (APASL): An update. Background: Acute on chronic liver disease is determined by the acute deterioration of liver function over a short period of time. J Hepatol 2013;59:24350. Post-traumatic stress in the intensive care unit. Lancet. 101. J Hepatol 2019;70:31927. Patients with chronic liver disease may progress to cirrhosis. The role of ACLF prediction, precipitating factors, individual organ failures, management strategies, and impact on liver transplantation or end-of-life care is evolving. 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). 29. Acute liver failure: summary of a workshop. In general, pharmacologic VTE prophylaxis has not been shown to increase the risk of bleeding; however, patients with recent bleeding (variceal hemorrhage before banding ulcers have healed and nonvariceal hemorrhage before healing has been achieved) and significant thrombocytopenia (platelets < 50 109/L) are not optimal candidates for pharmacologic VTE prophylaxis.

Norepinephrine is the vasopressor of choice in patients with ACLF. Liver Transpl 2020;26(12):165861. Patients with cirrhosis require admission to the ICU for support of failing organs. Patients with CKD can also develop an acute deterioration in renal function with prerenal azotemia or with the development of a bacterial infection. Subramanian KKK, Tandon M, Pandey CK, et al. Studies on ACLF focused on grade III/IV HE from Europe and North America showed that patients with HE as part of the ACLF syndrome had a worse prognosis than patients with HE but without ACLF (22,23). In determining factors associated with mortality at 2 months and 6 months, a combination of MELD score at baseline and response to treatment as determined by the Lille score at 7 days was superior to other combinations of scores (MDF + Lille; ABIC + Lille; and Glasgow alcoholic hepatitis score + Lille) (133). It should be noted that these artificial extracorporeal liver support systems can only perform the detoxifying functions of the liver. Gines P, Sola E, Angeli P, et al.

Subsequent analysis of the ANSWER trial showed that reaching a serum albumin of 4.0 g/dL provided the best improvement for survival (174). Rating the quality of evidence. The current definitions of ACLF vary worldwide, but despite these differences, patients with ACLF have a uniformly poor prognosis. 80. In patients with cirrhosis and chronic liver disease, acute-on-chronic liver failure is emerging as a major cause of mortality. Association between grade of acute on chronic liver failure and response to terlipressin and albumin in patients with hepatorenal syndrome. Am J Gastroenterol. When these observations were extended into a multicenter study, gut microbial composition on admission predicted outcomes (20). Bajaj JS, Tandon P, O'Leary JG, et al. Increasingly, more patients developed ACLF during longer term follow-up, with eventually 40% of patients developing ACLF at the end of 1 year. 180. Acute liver failure: When liver failure develops rapidly, typically over days to a few weeks, it is known as acute liver failure. 184. Higher mean arterial blood pressure (MAP) may decrease the risk of ACLF. LT may be considered in highly selected patients (137,138). Because urinary tract infections are a common nosocomial infection, and Foley catheter placement is the greatest risk of urinary tract infection development, Foley catheters should never be used to monitor urine output nor in patients for the simple reason of limited mobility. Other factors that have been studied to predict mortality in patients with cirrhosis undergoing elective surgery include American Society of Anesthesiology class, high-risk surgery such as cardiovascular and open abdominal surgery vs all other types of surgery which are considered lower risk, and the level of the hepatic venous pressure gradient (HVPG) (153). Treatment with non-selective beta blockers is associated with reduced severity of systemic inflammation and improved survival of patients with acute-on-chronic liver failure. Redefining cirrhotic cardiomyopathy for the modern era. However, when TEG or ROTEM values are abnormal, clear cutoffs for type and number of transfusions needed have not been developed. Hepatology 2020;72(3):110916. Cao Z, Liu Y, Wang S, et al. JAMA 2020;323(7):61626. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not only, approach to clinical scenarios. Side effects of norepinephrine include arrhythmias, bradycardia, and tissue ischemia. J Hepatol 2016;64:57482. Table 6 lists several future important aspects of ACLF that need to be investigated to improve the translational insight and clinical management of this growing population. These guidelines indicate the preferred approach to the management of patients with acute-on-chronic liver failure and represent the official practice recommendations of the American College of Gastroenterology.
