Liver failure in the context of acute (ALF) and acute on chronic liver failure (ACLF) is associated with high mortality in the absence of a liver transplant.

Acute liver failure (ALF) is an infrequent, unpredictable clinical sequela of acute liver injury (ALI) in an individual without any previous history of liver disease and is associated with a mortality rate of 50% to 75%. 1 Encephalopathy subsequent to ALI (icterus) is the usual presentation in ALF, and coagulopathy (international normalized ratio [INR] >1.5) is frequent. 1 The etiology of ALF is geographically distinct with varying icterus-encephalopathy interval (IEI), from 4 weeks in India to 26 weeks in the United States. 2 In the United Kingdom, United States, and Europe, ALF etiology is heterogenous (paracetamol, nonsteroidal anti-inflammatory drugs [NSAIDs], autoimmune hepatitis [AIH], and metabolic diseases). 2 In India, ALF has a homogeneous etiology (hepatitis virus in 90%). 1,2 Etiology influences phenotypic presentation.In the United Kingdom, Japan, and France, ALF with IEI of 1 week or 10 days had significantly higher survival than with IEI of longer than 1 week or 10 days, leading to subclassification in ALF as hyperacute (IEI ≤ 7 days), acute (IEI > 7 days to ≤4 weeks), and subacute (IEI of 5 to ≤12 weeks). 3 In India, as a result of homogenous etiology, rapidity of encephalopathy does not influence survival, and all ALF cases have IEI of ≤4 weeks. Therefore, the Indian National Association for the Study of Liver (INASL) consensus in ALF defines it "as a clinical syndrome characterized by encephalopathy, jaundice, and prolonged prothrombin time
Background
Acute‐on‐chronic liver failure (ACLF) is associated with a high short‐term mortality rate in the absence of liver transplantation. The role of therapeutic plasma exchange (TPE) in improving the outcomes of ACLF and acute decompensation (AD) is unclear. In this retrospective analysis, we aimed to determine the impact of TPE on mortality in patients with ACLF.
Methods
ACLF patients receiving TPE with standard medical treatment (SMT) were propensity score matched (PSM) with those receiving SMT alone (1:1) for sex, grades of ACLF, CLIF C ACLF scores, and the presence of hepatic encephalopathy. The primary outcomes assessed were mortality at 30 and 90 days. Survival analysis was performed using Kaplan Meier survival curves.
Results
A total of 1151 patients (ACLF n = 864 [75%], AD [without organ failure] n = 287 [25%]) were included. Of the patients with ACLF (n = 864), grade 1, 2, and 3 ACLF was present in 167 (19.3%), 325 (37.6%), and 372 (43.0%) patients, respectively. Thirty‐nine patients received TPE and SMT, and 1112 patients received only SMT. On PSM analysis, there were 38 patients in each group (SMT plus TPE vs SMT alone). In the matched cohort, the 30‐days mortality was lower in the TPE arm compared to SMT (21% vs 50%, P = .008), however, the 90‐day mortality was not significantly different between the two groups (36.8% vs 52.6%, P = .166); HR, 0.82 (0.44‐1.52), P = .549.
Conclusion
TPE improves short‐term survival in patients with ACLF, but has no significant impact on long‐term outcomes. Randomized control trials are needed to obtain a robust conclusion in this regard.
