This needs to be recognized as a potential sequela and managed appropriately once the patient has recovered. 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). HBV infection is the most common etiology of liver cirrhosis in Asian endemic countries. This meta-analysis was limited by high heterogeneity and analysis of multiple types of stem cells/stem cell sources together (mononuclear cells, mesenchymal stem cells, umbilical cord, and bone marrow). 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). Am J Gastroenterol 2019;114:8997. Proton pump inhibitor initiation and withdrawal affects gut microbiota and readmission risk in cirrhosis. [1] Recently, a third form of liver failure known as acute-on-chronic liver failure ( ACLF ) is increasingly being recognized. Fungal dysbiosis in cirrhosis. Literature related to DILI-induced ACLF is scarce. Loffredo L, Pastori D, Farcomeni A, et al. 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). 11. Course of ACLF. 110. 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. 15. In patients with cirrhosis and elevated baseline serum creatinine (sCr) who are admitted to the hospital, we suggest monitoring renal function closely because elevated baseline creatinine is associated with worse renal outcomes and 30-day survival (but no data that closer monitoring improves these outcomes) (very low quality, conditional recommendation). J Hepatol 2017;67:117784. The risk of ventilation-associated pneumonia can be decreased by 30- to 45-degree head-end elevation and subglottic suction. 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. ACLF is recognized by the presence of chronic liver disease along with elevation in the serum bilirubin and prolongation of the INR. Such a change in renal function is known as acute-on-CKD, defined as a rise in sCr of 50% from baseline or a rise of sCr by 0.3 mg/dL (26.4 mol/L) in <48 hours in a patient with cirrhosis whose glomerular filtration rate is <60 mL/min for >3 months calculated using the 6-parameter modification of diet in renal disease formula (37). Clin Gastroenterol Hepatol 2018;16:1792800.e3. Vuyyuru SK, Singh AD, Gamanagatti SR, et al. Association between intestinal microbiota collected at hospital admission and outcomes of patients with cirrhosis. 142. However, no significant between-group differences were observed for the key clinical variables, such as duration of ventilation and 28-day mortality (59). Despite the preponderance of HE as the cause of altered mental status, patients with cirrhosis are also prone to changes in mentation related to the medications above, infections, altered electrolytes, alcohol and illicit drugs, and strokes (27). Engelmann C, Herber A, Franke A, et al. The likelihood of fungal infections increases with greater number of organ failures, ACLF diagnosis, ICU transfer, diabetes, AKI, longer stay, and previous bacterial infection (87,105,106). It has been postulated that continued bacterial translocation post-TIPS insertion may be the trigger that drives an ongoing inflammatory response that is responsible for the development of ACLF. Given this high risk of mortality, we recommend early advance care planning in all patients admitted with ACLF, even when under consideration for LT. Studies evaluating outcomes after LT in patients with ACLF have demonstrated acceptable outcomes after LT, but should be interpreted with caution, given inherent selection bias toward transplanting only those who are most likely to achieve favorable outcomes (200202). In a nonrandomized study, patients with ACLF had a lower mortality if they were admitted on an NSBB than if they were not (116). [4]Bajaj JS, O'Leary JG, Lai JC, et al. Beneficial effects of statins on the rates of hepatic fibrosis, hepatic decompensation, and mortality in chronic liver disease: A systematic review and meta-analysis. 192. J Hepatol 2018;69:12178. 97. Hospitalized patients have the greatest extent of dysbiosis, and an altered microbial composition on admission is associated independently with ACLF development, organ failure, and death (16,90). Similarly, a higher neutrophil-lymphocyte ratio at admission portends an increased risk of mortality (96). Vaccinate patients with chronic liver disease against hepatitis A and hepatitis B if they are not already immune. This meta-analysis did not evaluate the effect of stem cell therapy on the definitive outcome of mortality. ACLF, acute-on-chronic liver failure; DILI, drug-induced liver injury; ICU, intensive care unit. 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). 57. Aliment Pharmacol Ther 2017;45:1390402. In patients with severe alcohol-associated hepatitis (MDF 32; MELD score > 20), we suggest against the use of pentoxifylline to improve 28-day mortality (very low quality, conditional recommendation).
