Determinants of Outcomes in Autoimmune Hepatitis Presenting as Acute on Chronic Liver Failure Without Extrahepatic Organ Dysfunction upon Treatment With Steroids.

Autoimmune hepatitis presenting as acute on chronic liver failure (AIH-ACLF) is a novel entity with limited data on clinical course and management. We assessed outcomes in patients of AIH-ACLF with no extrahepatic organ dysfunction/failure when administered steroids. In this retrospective analysis, clinical data, laboratory parameters, liver biopsy indices and prognostic scores such as model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores at baseline were computed for patients with AIH-ACLF and compared across strata of incident infections and transplant-free survival. The primary outcome was 90-day transplant-free survival. Biochemical remission was assessed, and predictors of end points were identified. Twenty-nine patients of AIH-ACLF were included with a median follow-up of 4 months. The 90- and 180-day transplant-free survival rates of 55.2 [95% confidence interval (CI): 39.7-76.6]% and 30.2(95% CI: 16.7-54.6)%, respectively, were attained on steroids. Three patients (10.3%) underwent liver transplant while 16 (55.2%) deaths occurred. Infections developed in 12 patients (41.3%), leading to worsening prognostic scores, new onset organ dysfunction/failure and 11 deaths. Seven of ten patients (70%) in the transplant-free survivor group attained biochemical remission on follow-up. The MELD score<24 (sensitivity: 68.4%; specificity: 80%) and CTP<11 (sensitivity: 78.9%; specificity: 90%) had best predictive value for survival, in addition to decrease in the MELD score at 2 weeks (sensitivity: 78.9%; specificity: 70%). Patients with AIH-ACLF have a morbid disease course despite treatment with steroids. Patients with no extrahepatic organ failure with good baseline prognostic scores may be administered steroids with close monitoring for change in MELD over 2 weeks.

Transplantation for EASL-CLIF and APASL acute-on-chronic liver failure (ACLF) patients: The TEA cohort to evaluate long-term post-Transplant outcomes.

The forecast accuracy of the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) and Asian Pacific Association for the Study of the Liver (APASL) acute-on-chronic liver failure (ACLF) criteria in assessing long-term outcomes after liver transplantation (LT) is still unclear, especially when the staging of the two standards is inconsistent. A retrospective cohort (NCT05036031) including 565 patients from January 2015 to June 2021 was conducted. The 28 and 90 days, 1- and 3-years overall survival (OS) after LT were compared between different grades. Total of 162 (28.7%) and 230 (40.7%) patients met the ACLF standards. In the EASL-CLIF criteria, the 3-year OS rates were 83·0%, 80·3%, and 69·8% for ACLF1-3, respectively. In the APASL criteria, the 3-year OS rates were 85·7% for APASL ACLF Research Consortium (AARC)-1, similar to ACLF-1. The 3-year OS rates were 84·5% for AARC-2, which were slightly better than ACLF-2. Regarding AARC-3, the 3-year OS rate was 5·8% higher than ACLF-3. For patients who met neither set of criteria for ACLF, the 3-year OS rates were 89·8%. The multivariate analysis showed that alanine aminotransferase >100 U/L, respiration failure, and cerebral failure were independent risk factors for post-LT death. This study provides the first large-scale long-term follow-up data in Asia. Both criteria showed favorable distinguishing ability for post-LT survival. Patients with ACLF had a higher post-LT mortality risk, and ACLF-3 and AARC-3 correlated with significantly greater mortality.

Identifying the early predictors of non-response to steroids in patients with flare of autoimmune hepatitis causing acute-on-chronic liver failure.

Early identification of non-response to steroids is critical in patients with autoimmune hepatitis (AIH) causing acute-on-chronic liver failure (ACLF). We assessed if this non-response can be accurately identified within first few days of treatment. Patients with AIH-ACLF without baseline infection/hepatic encephalopathy were identified from APASL ACLF research consortium (AARC) database. Diagnosis of AIH-ACLF was based mainly on histology. Those treated with steroids were assessed for non-response (defined as death or liver transplant at 90 days for present study). Laboratory parameters, AARC, and model for end-stage liver disease (MELD) scores were assessed at baseline and day 3 to identify early non-response. Utility of dynamic SURFASA score [- 6.80 + 1.92*(D0-INR) + 1.94*(∆%3-INR) + 1.64*(∆%3-bilirubin)] was also evaluated. The performance of early predictors was compared with changes in MELD score at 2 weeks. Fifty-five out of one hundred and sixty-five patients (age-38.2 ± 15.0 years, 67.2% females) with AIH-ACLF [median MELD 24 (IQR: 22-27); median AARC score 7 (6-9)] given oral prednisolone 40 (20-40) mg per day were analyzed. The 90 day transplant-free survival in this cohort was 45.7% with worse outcomes in those with incident infections (56% vs 28.0%, p = 0.03). The AUROC of pre-therapy AARC score [0.842 (95% CI 0.754-0.93)], MELD [0.837 (95% CI 0.733-0.94)] score and SURFASA score [0.795 (95% CI 0.678-0.911)] were as accurate as ∆MELD at 2 weeks [0.770 (95% CI 0.687-0.845), p = 0.526] and better than ∆MELD at 3 days [0.541 (95% CI 0.395, 0.687), p < 0.001] to predict non-response. Combination of AARC score > 6, MELD score > 24 with SURFASA score ≥ - 1.2, could identify non-responders at day 3 (concomitant- 75% vs either - 42%, p < 0.001). Baseline AARC score, MELD score, and the dynamic SURFASA score on day 3 can accurately identify early non-response to steroids in AIH-ACLF.

Approach to the patient with acute severe autoimmune hepatitis.

Autoimmune hepatitis is associated with varied clinical presentations and natural history, as well as somewhat unpredictable treatment responses. Understanding how to stratify patients who require further escalation of therapy will help clinicians manage these patients. The presentation of acute severe autoimmune hepatitis (AS-AIH) is relatively uncommon, although its prevalence is potentially greater than currently perceived. Previous studies consist of small retrospective single-centre series and are not directly comparable due to the diversity of presentations, disease definitions and non-standardised treatment regimens. We define AS-AIH as those who present acutely with AIH and are icteric with an international normalised ratio ≥1.5 and no evidence of hepatic encephalopathy. Those with hepatic encephalopathy should be defined as having AS-AIH with acute liver failure. In this review, we provide a structured practical approach for diagnosing and managing this unique group of patients.
