RESUMO
BACKGROUND & AIMS: Although the effect of bacterial infection on cirrhosis has been well-described, the effect of non-hepatotropic virus (NHV) infection is unknown. This study evaluated the genome fragments of circulating microorganisms using metagenomic next-generation sequencing (mNGS) in individuals with acute decompensation (AD) of cirrhosis, focusing on NHVs, and related the findings to clinical outcomes. METHODS: Plasma mNGS was performed in 129 individuals with AD of cirrhosis in the study cohort. Ten healthy volunteers and 20, 39, and 81 individuals with stable cirrhosis, severe sepsis and hematological malignancies, respectively, were enrolled as controls. Validation assays for human cytomegalovirus (CMV) reactivation were performed in a validation cohort (n = 58) and exploratory treatment was instituted. RESULTS: In the study cohort, 188 microorganisms were detected in 74.4% (96/129) of patients, including viruses (58.0%), bacteria (34.1%), fungi (7.4%) and chlamydia (0.5%). A NHV signature was identified in individuals with AD, and CMV was the most frequent NHV, which correlated with the clinical effect of empirical antibiotic treatment, progression to acute-on-chronic liver failure, and 90-day mortality. The NHV signature in individuals with acute-on-chronic liver failure was similar to that in those with sepsis and hematological malignancies. CMV was detected in 24.1% (14/58) of patients in the validation cohort. Of the 14 cases with detectable CMV by mNGS, nine were further validated by real-time PCR or pp65 antigenemia testing. Three patients with CMV reactivation received ganciclovir therapy in an exploratory manner and experienced clinical resolutions. CONCLUSIONS: The results of this study suggest that NHVs may play a pathogenic role in complicating the course of AD. Further validation is needed to define whether this should be incorporated into the routine management of individuals with AD of cirrhosis. IMPACT AND IMPLICATIONS: A non-hepatotropic virus (NHV) signature, which was similar to that in individuals with sepsis and hematological malignancies, was identified in individuals with acute decompensation of cirrhosis. The detected viral signature had clinical correlates, including clinical efficacy of empirical antibiotic treatment, progression to acute-on-chronic liver failure and short-term mortality. Cytomegalovirus reactivation, which is treatable, may adversely affect clinical outcomes in some individuals with decompensated cirrhosis. Routine screening for NHVs, especially cytomegalovirus, may be useful for the management of individuals with acute decompensation of cirrhosis.

BACKGROUND & AIMS: The Baveno VII consensus recommends that spleen stiffness measurement (SSM) ≤40 kPa is safe for ruling out high-risk varices (HRVs) and avoiding endoscopic screening in patients who do not meet the Baveno VI criteria. This study aimed to validate the performance of the Baveno VII algorithm in individuals with HBV-related cirrhosis. METHODS: Consecutive individuals with HBV-related cirrhosis who underwent liver stiffness measurement (LSM) and SSM - using a 50 Hz shear wave frequency, spleen diameter measurement, and esophagogastroduodenoscopy (EGD) were prospectively enrolled from June 2020. A 100 Hz probe has been adopted for additional SSM assessment since July 2021. RESULTS: From June 2020 to January 2022, 996 patients were screened and 504 were enrolled for analysis. Among the 504 patients in whom SSM was assessed using a 50 Hz probe, the Baveno VII algorithm avoided more EGDs (56.7% vs. 39.1%, p <0.001) than Baveno VI criteria, with a comparable missed HRV rate (3.8% vs. 2.5%). Missed HRV rates were >5% for all other measures: 11.3% for LSM-longitudinal spleen diameter to platelet ratio score, 20.0% for platelet count/longitudinal spleen diameter ratio, and 8.8% for Rete Sicilia Selezione Terapia-hepatitis. SSM@100 Hz was assessed in 232 patients, and the Baveno VII algorithm with SSM@100 Hz spared more EGDs (75.4% vs. 59.5%, p <0.001) than that with SSM@50 Hz, both with a missed HRV rate of 3.0% (1/33). CONCLUSIONS: We validated the Baveno VII algorithm, demonstrating the excellent performance of SSM@50 Hz and SSM@100 Hz in ruling out HRV in individuals with HBV-related cirrhosis. Furthermore, the Baveno VII algorithm with SSM@100 Hz could safely rule out more EGDs than that with SSM@50 Hz. CLINICAL TRIAL NUMBER: NCT04890730. IMPACT AND IMPLICATIONS: The Baveno VII guideline proposed that for patients who do not meet the Baveno VI criteria, SSM ≤40 kPa could avoid further unnecessary endoscopic screening. The current study validated the Baveno VII algorithm using 50 Hz and 100 Hz probes, which both exhibited excellent performance in ruling out HRVs in individuals with HBV-related cirrhosis. Compared with the Baveno VII algorithm with SSM@50 Hz, SSM@100 Hz had a better capability to safely rule out unnecessary EGDs. Baveno VII algorithm will be a practical tool to triage individuals with cirrhosis in future clinical practice.

Empirical antibiotic therapy in patients with spontaneous bacterial peritonitis (SBP) is common as pathogen(s) are identified in only 5%-20% patients using conventional culture-based techniques. Metagenome next-generation sequencing (mNGS) test is a promising approach for the diagnosis of infectious disease. The clinical application of mNGS for infected ascites in cirrhotic patients is rarely reported. Here, we describe three cases to preliminarily explore the potential role of mNGS for microbiological diagnosis of ascites infection in an exploratory manner. The clinical performance of ascites mNGS in cirrhotic patients remains to be further evaluated.

BACKGROUND & AIMS: There are no data validating the performance of spleen stiffness measurement in ruling out high-risk varices in patients with HBV-related cirrhosis under maintained viral suppression. Thus, we aimed to prospectively validate the performance of spleen stiffness measurement (cut-off 46 kPa) combined with Baveno VI criteria in ruling out high-risk varices in these patients. METHODS: Patients with cirrhosis were enrolled from April to December 2019 at the hepatology unit of the Nanfang Hospital, China. Liver and spleen transient elastography and esophagogastroduodenoscopy were performed at enrollment. Antiviral regimen(s) and virological responses, evaluated every 3-6 months, were recorded. RESULTS: Overall 341 patients with HBV-related cirrhosis under maintained viral suppression were enrolled, and the prevalence of high-risk varices was 20.5% (70/341). Baveno VI criteria spared 37.0% (126/341) esophagogastroduodenoscopies and no high-risk varices were missed (0/70). Eight cases of high-risk varices (8/70, 11.4%) were misclassified in patients (208/341, 61.0%) within the expanded Baveno VI criteria. The spleen stiffness measurement cut-off (≤46.0 kPa) was shown to safely rule out high-risk varices in these patients (the percentage of missed high-risk varices was 4.3%). Over half (61.6%, 210/341) of patients met the combined model (Baveno VI criteria and spleen stiffness measurement cut-off ≤46 kPa) and 4.3% (3/70) of high-risk varices cases were misclassified. This combined model exhibited a sensitivity of 95.71%, specificity of 76.38%, negative predictive value of 98.57%, and negative likelihood ratio of 0.06 for ruling out high-risk varices. CONCLUSIONS: We validated the excellent performance of Baveno VI criteria combined with spleen stiffness measurement (cut-off 46 kPa) for safely ruling out high-risk varices in patients with HBV-related cirrhosis under viral suppression; more than half of esophagogastroduodenoscopy procedures were spared using this combination. CLINICAL TRIAL NUMBER: NCT04123509 LAY SUMMARY: Esophageal varices have important prognostic implications in patients with cirrhosis. Thus, their timely identification is important so that treatment can be initiated early. Herein, we validated the excellent performance of the combination of Baveno VI criteria with spleen stiffness measurement (cut-off 46 kPa) for ruling out high-risk esophageal varices in patients with HBV-related cirrhosis under maintained viral suppression (with antiviral treatment). This combined model was able to safely rule out high-risk varices (missed/total <5%) and over half (61.6%) of esophagogastroduodenoscopy procedures were spared.

BACKGROUND AND AIM: Tri-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. METHODS: Hospitalized 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. RESULTS: Compared 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%). CONCLUSION: Tri-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: Acute-on-chronic liver failure (ACLF) is a syndrome characterized by profound disrupted coagulation and fibrinolysis. Fibrinolytic marker D-dimer is increased in critically ill patients with cirrhosis which is associated with poorer prognosis. We aim to determine the potential association of D-dimer with the 28-day mortality in ACLF patients. METHODS: In a single center retrospective study performed in China, we collected data of 115 patients with ACLF from October 1, 2012 to December 31, 2016. We investigated correlations between D-dimer and other laboratory tests and prognostic scores. The relationship between D-dimer and 28-day mortality was explored by smoothing plot with an adjustment for potential confounders. Logistic regression analyses with crude and adjusted models were performed to explore the association of D-dimer with 28-day mortality in ACLF patients. RESULTS: In ACLF patients, D-dimer at admission was correlated with all prognostic scores (MELD-Na: r = 0.385, P < 0.001; CLIF-C ADs: r = 0.443, P < 0.001; CLIF-C ACLFs: r = 0.375, P < 0.001). A nonlinear relation between D-dimer and 28-day mortality was found with a turning point at 6.5 mg/L FEU. D-dimer level was independently associated with 28-day mortality with an adjusted odds ratio of [1.4 (1.0-1.9), P = 0.030] as continuous variable and [10.3 (1.3, 81.5), P = 0.028] as a classified variable with the cut-off of 6.5 mg/L FEU. An elevated D-dimer within the following 10 days also tended to be associated with higher risk of 28-day mortality [OR: 27.5 (0.9, 814.9), P = 0.055]. CONCLUSIONS: Elevated D-dimer levels was associated with increased risk of 28-day mortality in patients with ACLF in China.

BACKGROUND: Esophagogastroduodenoscopy (EGD) is required to screen for high-risk varices (HRV) in patients with hepatocellular carcinoma (HCC), especially since overall survival rates have dramatically improved with new systemic therapies. AIM: To assess the Baveno VI and Baveno VII algorithms' ability to rule out HRV in hepatitis B virus (HBV)-related HCC METHODS: We prospectively enrolled consecutive patients with HBV related, compensated cirrhosis and newly diagnosed HCC who underwent liver stiffness measurement, spleen stiffness measurement (SSM) using a 100-Hz shear wave frequency, and EGD. RESULTS: From September 2021 to August 2023, we enrolled 219 patients with HCC, with 107 (48.9%) Barcelona Clinic Liver Cancer (BCLC) A, 28 (12.8%) BCLC B and 84 (38.3%) BCLC C, respectively. HRV prevalence was 28.8% (63/219). Baveno VI criteria safely (HRV missing rate, 3.2%) avoided 27.4% unnecessary EGDs, while the Baveno VII algorithm avoided 49.3% with HRV missing rate at 7.9% (5/63). The SSM ≤40 kPa avoided 47.5% of EGDs safely (HRV missing rate, 4.8%), significantly better than the Baveno VI criteria (p < 0.001) and comparable to the Baveno VII algorithm (p = 0.390). The SSM ≤40 kPa safely avoided EGDs in patient subgroups within Milan criteria, with portal vein tumour thrombosis or BCLC B/C or candidates for systemic therapy. CONCLUSIONS: We validated that the SSM ≤40 kPa using a 100-Hz probe could safely eliminate more unnecessary EGDs than the Baveno VI criteria in patients with HBV-related HCC. However, the efficacy of the Baveno VII algorithm in patients with HCC requires further investigation.

AIMS: To prospectively evaluate the performance of spleen stiffness measurement (SSM) and liver stiffness measurement (LSM) via acoustic radiation force impulse (ARFI) imaging combined with platelet counts (PLT) in ruling out HRV in HBV-related cirrhotic patients with viral suppression. METHODS: Patients with cirrhosis enrolled between June 2020-March 2022 were divided into a derivation cohort and validation cohort. LSM and SSM ARFI-based, and esophagogastroduodenoscopy (EGD) were performed at enrollment. RESULTS: In the derivation cohort, overall, 236 HBV-related cirrhotic patients with maintained viral suppression were enrolled, and the prevalence of HRV was 19.5% (46/236). With the aim of identifying HRV, the most accurate LSM and SSM cut-offs were chosen of 1.46 m/s and 2.28 m/s, respectively. The combined model (LSM<1.46 m/s and PLT>150 × 109/L strategy combined with SSM ≤ 2.28 m/s) can spare 38.6% of EGDs and 4.3% of HRV cases were misclassified. In the validation cohort, we analysed 323 HBV-related cirrhotic patients with maintained viral suppression and validated the combined model can spare 33.4% (108/323) of EGD, and the HRV missed rate was 3.4%. CONCLUSIONS: A non-invasive prediction model combining LSM<1.46 m/s and PLT>150 × 109/L strategy with SSM ≤ 2.28 m/s exhibited excellent performance in ruling out HRV and avoided a significantly large number (38.6% vs 33.4%) of unnecessary EGDs in HBV-related cirrhotic patients with viral suppression.

The mortality of acute-on-chronic liver failure (ACLF) patients complicated with invasive pulmonary aspergillosis (IPA) was extremely high. We aimed to explore prognostic value of the Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) lung score and to establish an optimal voriconazole regimen for ACLF patients complicated with IPA. We retrospectively screened hospitalized ACLF patients in our hospital from July 2011 to April 2016, from which 20 probable IPA cases were diagnosed. Along with onsets of IPA, deteriorated diseases severity, especially lung conditions were found in those 20 ACLF patients. It was found that IPA patients with CLIF-SOFA lung score <2 had better 28-day survival than those with lung score >1 (11/13 vs 0/7, p < 0.001). Based on plasma voriconazole concentration measurement, an optimal voriconazole regimen (loading doses: 0.2 g twice daily; maintenance doses, 0.1 g once daily) was established, which resulted in rational trough plasma drug concentrations (1-5 µg/mL), good clinical outcomes (90-day survival rate of 6/8) and no observed adverse events. In conclusion, CLIF-SOFA lung score >1 was able to identify ACLF patients complicated with IPA encountering much higher 28-day mortality. An optimal voriconazole regimen was safe and effective in our ACLF patients complicated with IPA.

OBJECTIVE: To explore the long-term prognosis and health-related quality of life of patients surviving hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). METHODS: The clinical data were collected from patients with HBV-ACLF, who were hospitalized in our department between November, 2011 and October, 2016 and survived for more than 90 days. The patients were followed for occurrence of newly diagnosed cirrhosis, decompensation events, hepatocellular carcinoma and death. The quality of life of the patients was evaluated using SF-36 score, and the patients with chronic hepatitis B (CHB) and cirrhosis treated during the same period served as controls. RESULTS: A total of 223 ACLF survivors were included in this study. According to the presence of cirrhosis on admission, the enrolled patients were divided into chronic hepatitis B-related ACLF (CHB-ACLF) group (n=130) and liver cirrhosis ACLF (CIR-ACLF) group (n=93). The 12-, 24- and 50-month survival rates in CHB-ACLF group were 97%, 95.7% and 93.9%, respectively, significantly higher than the rates in CIR-ACLF group (91%, 86% and 74%, respectively; P=0.007). In patients with CHB-ACLF, the 12-, 24- and 36-month progression rates of cirrhosis were 37.9%, 58.4% and 68.7% respectively. Multivariate Cox regression identified the peak value of serum creatinine (HR=1.015, P=0.026) and INR (HR=2.032, P=0.006) within 28 days as independent risk factors and serum sodium at baseline (HR=0.84, P=0.035) as an independent protective factor of occurrence of cirrhosis. The score of mental health on SF-36 in ACLF group was significantly lower than the national norms, and the scores for general health and body pain of ACLF patients were significantly higher than those in patients with CHB or cirrhosis. CONCLUSION: The long-term prognosis of ACLF survivors with and without cirrhosis can be different. Acute attacks are associated with an increased rate of cirrhosis progression in CHB patients who recovered from ACLF, possibly in relation with the severity of extra-hepatic organ injuries. The physical and social functions of long-term survivors of ACLF do not significantly decline, but their psychological status can be affected.

OBJECTIVE: To observe the clinical characteristics and short-term survival of patients with splenomegaly and acute-on-chronic liver failure related to chronic HBV infection. METHODS: Electronic medical records of patients with acute-on-chronic liver failure were collected to analyze the clinical parameters and 4-week survival of patients with or without splenomegaly. RESULTS: Of the 149 patients enrolled, the overall 28-day mortality rate was 48.3%, which was lower in patients with enlarged spleen than those without (34.2% vs 54.1%, P=0.034). Compared with patients without splenomegaly, patients with splenomegaly had lower platelet counts (P=0.001), lower ALT levels (P=0.005) and lower PT-INR (P=0.010). Although the occurrence of hepatic encephalopathy was comparable between patients with or without splenomegaly, severe conditions were more frequent in those without splenomegaly. Hepatic encephalopathy grades, serum creatinine levels, neutrophil percentages over 70%, PT-INR and splenomegaly were independent factors associated with the 28-day survival, and this novel model was superior to model of end-stage of liver disease in predicting the 4-week survival (P=0.017). CONCLUSION: Patients with splenomegaly that evolves into acute-on-chronic liver failure have unique clinical characteristics and further clinical observations are warranted.
