Background/Aims
The role of reactivation of human cytomegalovirus (HCMV) in determining outcomes of cirrhotic patients with acute decompensation (AD) is unknown. We aimed to investigate HCMV incidence and potential correlation with hepatic outcomes in AD patients.
Methods
Two prospective multicentre cohorts with AD patients were investigated. Patients in cohort 1 were recruited from 4 centres, while patients in cohort 2 were randomly selected from a second multicentre cohort. HCMV reactivation was established with quantitative real-time polymerase chain reaction assay in seropositive patients.
Results
HCMV reactivation was found in 35 patients from cohort 1 (n=722) and 14 from cohort 2 (n=291), with an incidence of 4.8% in both cohorts. Bacterial infection and liver failure were independently correlated with HCMV reactivation. HCMV reactivation was an independent predictor of 90-day mortality. Among bacterial infection populations in these two cohorts, patients with HCMV reactivation had worse prognosis compared to those without. Incidence of acute-on-chronic liver failure (ACLF) was higher in patients with HCMV reactivation compared to those without and was also independently correlated with development of ACLF. In a total of 49 HCMV reactivation cases, 8 patients were treated with ganciclovir, in whom a significantly lower 90-day mortality compared with those not treated was observed. All 3 patients who underwent liver transplantation with reactivation of HCMV died.
Conclusions
In AD patients, HCMV reactivation was common, especially in those with bacterial infection or liver failure, and they were more prone to having ACLF and 90‑day mortality. The data propose the need for active surveillance for HCMV infection in AD patients.

Background/Aims
Cirrhotic patients with liver stiffness measurement (LSM) <20 kPa and platelet count ≥150×10⁹/L (Baveno VI criteria), otherwise spleen stiffness measurement (SSM) ≤40 kPa (Baveno VI-SSM criteria) can avoid endoscopy screening; however, no prospective data for their hepatic outcomes.
Methods
Compensated cirrhosis with HBV were prospectively enrolled from April 2019 to April 2022 and followed until July 2023. All patients underwent LSM, SSM and esophagogastroduodenoscopy assessment.
Results
Among 1,224 patients enrolled with median follow-up of 30 months (interquartile range, 21–42), the incidence of decompensation was greater in 560 patients with unfavored Baveno VI criteria (0.5 vs. 20.4 per 1,000 person-years, P=0.0004) than that in 664 patients with favored Baveno VI-SSM criteria. The Baveno VI-SSM model identified more patients (54.2%) as low-risk for decompensation than Baveno VII-SSM model (single cutoff) (48.4%, P=0.004) and than Baveno VI criteria (34.6%, P<0.0001) did. Patients with high-risk varices diagnosed via endoscopy following Baveno VI-SSM model assessment had greater probability of decompensation compared to those identified by the Baveno VII-SSM model (single cutoff) (42.8 vs. 21.1 per 1,000 person-years, P=0.0088). Additionally, among the 493 patients who underwent endoscopic re-assessment, 242 patients with favored Baveno VI-SSM criteria had much lower incidence of EV progression (2.6 vs. 99.5 per 1,000 person-years, P=0.0004) and lower risk of decompensation compared to 140 patients with unfavored Baveno VI-SSM model (0 vs. 34.2 per 1,000 person-years, P=0.0256).
Conclusions
Baveno VI-SSM model could identify HBV-related cirrhosis patients at low risk of decompensation, which was greatly improved upon Baveno VI-SSM reassessment.
