ABSTRACT

BACKGROUND & AIMS: Acute-on-chronic liver failure (ACLF) is characterised by the presence of organ failure in patients with decompensated cirrhosis and is associated with high short-term mortality. However, there are limited data on the prevalence and short-term outcomes of ACLF in patients with cirrhosis seen in the US. We aimed to study the prevalence and risk factors associated with the development and short term mortality in a large cohort of patients in the US. METHODS: Using the US Department of Veterans Affairs (VA) Corporate Data Warehouse, we identified patients with ACLF during hospitalisation for decompensated cirrhosis at any of the 127 VA hospitals between January 1, 2004, and December 31, 2014. We examined the prevalence of ACLF and variables associated with 28- and 90-day mortality in ACLF, and trends in prevalence and survival over time. RESULTS: Of 72,316 patients hospitalised for decompensated cirrhosis, 19,082 (26.4%) patients met the criteria of ACLF on admission. Of these, 12.8% had 1, 10.1% had 2, and 3.5% had 3 or more organ failures. Overall, 25.5% and 40.0% of ACLF patients died within 28 days and 90 days of admission, respectively. Older age, White race, liver cancer, higher model for end-stage liver disease sodium corrected score, and non-liver transplant centre were associated with increased risk of death in ACLF. Over the study period, the prevalence of ACLF decreased, and all grades but ACLF-3 had improvement in survival. CONCLUSIONS: In a US cohort of hospitalised patients with decompensated cirrhosis, ACLF was common and associated with high short-term mortality. Over a decade, ACLF prevalence decreased but survival improvement of ACLF-3 was not seen. Early recognition and aggressive management including timely referral to transplant centres may lead to improved outcomes in ACLF. LAY SUMMARY: Acute-on-chronic liver failure (ACLF) is a condition marked by multiple organ failures in patients with cirrhosis and associated with a high risk of death. In this study of US patients hospitalised with cirrhosis, 1 in 4 patients developed ACLF. In total, 25% of patients with ACLF died within 1 month and 40% died within 3 months. Thus, early recognition of ACLF is important for the initiation of aggressive management, which is required to save these patients' lives.

ABSTRACT

Objective: To evaluate the incidence, and the characteristics of organ failure in relationship to prognosis in hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) patients using chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score for judgments of clinical treatment and prognosis. Methods: Clinical data of 316 patients who were diagnosed as HBV-ACLF during hospitalization from February 2015 to February 2016 were retrospectively analyzed. Intrahepatic and extrahepatic organ failures were assessed according to CLIF-SOFA score, and the relationship between clinical characteristics and prognosis was analyzed. Continuity variables were analyzed by analysis of variance, or Kruskal-Wallis H test. Comparison of the categorical data were done using χ (2) or Fisher's exact test, and the predictive efficacy of various prognostic scores was compared using the area under the receiver operating characteristic curve (AUROC) and Z-test. Results: Of 316 cases (87.3% men) of HBV-ACLF, the mean age was (45 ± 11) years old. 78.8% of patients with underlying liver disease had hepatitis B virus induced cirrhosis. Mortality rates in patients without liver transplantation at 28 days, 90 days and 180 days were 20.5% (63/307), 36.7% (110/300) and 39.2% (116/296), respectively. According to the CLIF-SOFA score, 89.9% (284 patients) had organ failure at baseline, of which 97.5% had liver failure (Total bilirubin ≥ 12 mg/dl) and only 2.5% had coagulation, kidney, circulation or respiratory failure without liver failure. Besides liver failure, the incidence of extrahepatic organ failure was coagulation (23.1%), kidney (5.7%), brain (3.8%), circulation (1.3%) and respiratory failure (0.3%). With increasing number of organ failure, the mortality rate of two and three or more organ failures were 69.6% and 69.2%, respectively, which was significantly higher than that of single organ failure and non-organ failure patients (27% and 6.9%, respectively; P < 0.001). Liver failure with coagulation failure (International normalized ratio≥2.5 or platelet count≤20×10(9)/L) had worst prognosis with a mortality rate of up to 75% at 90 days. Conclusion: According to the CLIF-SOFA score, the main organ failure in patients with HBV-ACLF in China is liver failure. The mortality rate in patients with two or more organ failures is as high as 70% within 3 months. Therefore, timely manner liver transplantation should be considered.

ABSTRACT

OBJECTIVE: To determine dynamic Gc-globulin level change in Acute-on-Chronic Hepatitis B Liver Failure (ACHBLF) patients, and evaluate the prognostic value of Gc-globulin. STUDY DESIGN: An analytical study. PLACE AND DURATION OF STUDY: The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou, China, from January 2010 to December 2012. METHODOLOGY: A total of 54 consecutive Chinese ACHBLF patients and 30 healthy volunteers as controls were recruited from 2010 to 2012. The patients were divided into improved group and aggravated group. Gc-globulin levels were determined in both groups and mean values compared with significance at p < 0.05. Cut-off value was also determined. RESULTS: The Gc-globulin level was significantly decreased in ACHBLF patients (p < 0.001). Gc-globulin levels were significantly higher in improved patients than in aggravated patients, and a 215 mg/L cut-off value carried the best prognostic information. On longitudinal observations, Gc-globulin gradually elevated in improved groups. However, in aggravated groups, the Gc-globulin levels were always below normal levels and no significant change was observed before or after the treatment (p > 0.05). CONCLUSION: Gc-globulin monitoring offers a rapid and accurate method to estimate treatment outcomes on admission and an effective temporal indicator of curative effects in ACHBLF patients at an optimal cut-off value of 215 mg/L.

ABSTRACT

Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin's lymphoma (NHL) with increasing incidence in older males, females and blacks. However, it has not yet been reported, to present with acute liver failure in patients with preexisting chronic liver disease due to human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. We describe a case of ACLF as the presenting manifestation of DLBCL in an elderly black man with HIV/HCV co-infection and prior Hodgkin's disease in remission for three years. The rapidly fatal outcome of this disease is highlighted as is the distinction of ACLF from decompensated cirrhosis. Due to the increased prevalence of HIV/HCV co-infection in the African American 1945 to 1965 birth cohort and the fact that both are risk factors for chronic liver disease and NHL we postulate that the incidence of NHL presenting as ACLF may increase.

ABSTRACT

AIM: To compare the utility of the Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) and Asia-Pacific Association for the Study of Liver (APASL) definitions of acute-on-chronic liver failure (ACLF) in predicting short-term prognosis of patients with ACLF. METHODS: Consecutive patients of cirrhosis with acute decompensation were prospectively included. They were grouped into ACLF and no ACLF groups as per CLIF-SOFA and APASL criteria. Patients were followed up for 3 mo from inclusion or mortality whichever was earlier. Mortality at 28-d and 90-d was compared between no ACLF and ACLF groups as per both criteria. Mortality was also compared between different grades of ACLF as per CLIF-SOFA criteria. Prognostic scores like CLIF-SOFA, Acute Physiology and Chronic Health Evaluation (APACHE)-II, Child-Pugh and Model for End-Stage Liver Disease (MELD) scores were evaluated for their ability to predict 28-d mortality using area under receiver operating curves (AUROC). RESULTS: Of 50 patients, 38 had ACLF as per CLIF-SOFA and 19 as per APASL criteria. Males (86%) were predominant, alcoholic liver disease (68%) was the most common etiology of cirrhosis, sepsis (66%) was the most common cause of acute decompensation while infection (66%) was the most common precipitant of acute decompensation. The 28-d mortality in no ACLF and ACLF groups was 8.3% and 47.4% (P = 0.018) as per CLIF-SOFA and 39% and 37% (P = 0.895) as per APASL criteria. The 28-d mortality in patients with no ACLF (n = 12), ACLF grade 1 (n = 11), ACLF grade 2 (n = 14) and ACLF grade 3 (n = 13) as per CLIF-SOFA criteria was 8.3%, 18.2%, 42.9% and 76.9% (χ(2) for trend, P = 0.002) and 90-d mortality was 16.7%, 27.3%, 78.6% and 100% (χ(2) for trend, P < 0.0001) respectively. Patients with prior decompensation had similar 28-d and 90-d mortality (39.3% and 53.6%) as patients without prior decompensation (36.4% and 63.6%) (P = NS). AUROCs for 28-d mortality were 0.795, 0.787, 0.739 and 0.710 for CLIF-SOFA, APACHE-II, Child-Pugh and MELD scores respectively. On multivariate analysis of these scores, CLIF-SOFA was the only significant independent predictor of mortality with an odds ratio 1.538 (95%CI: 1.078-2.194). CONCLUSION: CLIF-SOFA criteria is better than APASL criteria to classify patients into ACLF based on their prognosis. CLIF-SOFA score is the best predictor of short-term mortality.
