This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e135. Learning Objective-Upon completion of this activity, successful learners will be able to list the criteria for diagnosis of cirrhosis with acute decompensation; list at least 1 independent risk factor for portal vein thrombosis in patients with cirrhosis and acute decompensation; list 3 indicators for acute decompensation in patients with cirrhosis; and know the impact of portal vein thrombosis on 1-year mortality in patients with cirrhosis and acute decompensation. BACKGROUND & AIMS: Portal vein thrombosis (PVT) is a common and serious complication in patients with cirrhosis. However, little is known about PVT in patients with cirrhosis and acute decompensation (AD). We investigated the prevalence and clinical significance of PVT in nonmalignant patients with cirrhosis and AD. METHODS: We performed a retrospective study of 2 cohorts of patients with acute exacerbation of chronic liver disease who participated in the Chinese AcuTe on CHronic LIver FailurE study, established by
Background and AimTri‐typing of acute‐on‐chronic liver failure (ACLF), as proposed by the World Gastroenterology Organization (WGO), has not been validated in patients infected with hepatitis B virus (HBV). We aim to compare the three types of ACLF patients in clinic characteristics.MethodsHospitalized ACLF patients with chronic hepatitis B from five hepatology centers were retrospectively selected and grouped according to the WGO classification. For each group, we investigated laboratory tests, precipitating events, organ failure, and clinical outcome.ResultsCompared with type‐B (n = 262, compensated cirrhosis) and type‐C (n = 129, decompensated cirrhosis) ACLF, type‐A patients (n = 195, non‐cirrhosis) were associated with a younger age, the highest platelet counts, the highest aminotransferase levels, and the most active HBV replications. HBV reactivation were more predominant in type‐A, while bacterial infections in type‐B and type‐C ACLF cases. Liver failure (97.4%) and coagulation failure (86.7%) were most common in type‐A compared with type‐B or type‐C ACLF patients. Kidney failure was predominantly identified in type‐C subjects (41.9%) and was highest (23/38, 60.5%) in grade 1 ACLF patients. Furthermore, type‐C ACLF showed the highest 28‐day (65.2%) and 90‐day (75.3%) mortalities, compared with type‐A (48.7% and 54.4%, respectively) and type‐B (48.4% and 62.8%, respectively) ACLF cases. Compared with type‐A (11.7%) ACLF patients, the increased mortality from 28 to 90 days was higher in type‐B (31.6%) and type‐C (37.5%).ConclusionTri‐typing of HBV‐related ACLF in accordance with the WGO definition was able to distinguish clinical characteristics, including precipitating events, organ failure, and short‐term prognosis in ACLF patients.
Background and AimsHepatitis B virus (HBV) reactivation is a serious condition and has been extensively described in chemotherapeutic immunosuppressive population. However, little is known about HBV reactivation in immunocompetent patients with chronic hepatitis B (CHB). In this study, we evaluated the prevalence and the clinical significance of HBV reactivation in CHB patients with acute exacerbations.MethodPatients were screened from two prospective multicenter observational cohorts (CATCH-LIFE cohort). A total of 1,020 CHB patients with previous antiviral treatment history were included to assess the prevalence, risk factors, clinical characteristics of HBV reactivation, and its influence on the progression of chronic liver disease.ResultsThe prevalence of HBV reactivation was 51.9% in CHB patients with acute exacerbations who had antiviral treatment history in our study. Among the 529 patients with HBV reactivation, 70.9% of them were triggered by discontinued antiviral treatment and 5.9% by nucleos(t)ide analogs (NUCs) resistance. The prevalence of antiviral treatment disruption and NUCs resistance in patients with HBV reactivation is much higher than that in the patients without (70.9% vs. 0.2%, and 5.9% vs. 0, respectively, both p < 0.001). Stratified and interaction analysis showed that HBV reactivation was correlated with high short-term mortality in cirrhosis subgroup (HR = 2.1, p < 0.001). Cirrhotic patients with HBV reactivation had a significantly higher proportion of developing hepatic failure (45.0% vs. 20.3%, p < 0.001), acute-on-chronic liver failure (ACLF; 31.4% vs. 21.8%, p = 0.005), and short-term death (14.0% vs. 5.9% for 28-day, and 23.3% vs. 12.4% for 90-day, both p < 0.001) than those without. HBV reactivation is an independent risk factor of 90-day mortality for cirrhosis patients (OR = 1.70, p = 0.005), as well as hepatic encephalopathy, ascites, and bacterial infection.ConclusionThis study clearly demonstrated that there was a high prevalence of HBV reactivation in CHB patients, which was mainly triggered by discontinued antiviral treatment. The HBV reactivation strongly increased the risk of developing hepatic failure, ACLF and short-term death in HBV-related cirrhotic patients, which may suggest that HBV reactivation would be a new challenge in achieving the WHO target of 65% reduction in mortality from hepatitis B by 2030.
