HCC incidence varies markedly depending on the underlying cause of cirrhosis. Herein, using readily available clinical and laboratory parameters we describe a risk score, THRI, which has a good predictive ability for HCC in patients with cirrhosis, and has been validated in an external cohort. This risk score may help to guide recommendations regarding HCC surveillance among patients with cirrhosis.

ObjectiveAlthough most patients with chronic hepatitis B (CHB) reach effective virological suppression with long-term nucleos(t)ide analogues (NA) therapy, some might not need to continue treatment for life. In this randomised, controlled, phase IV trial, we evaluated off-therapy outcomes in patients after discontinuing long-term NA therapy.DesignPatients who had received NA therapy for ≥1 year and achieved virological suppression (hepatitis B e antigen (HBeAg) seroconversion combined with undetectable hepatitis B virus (HBV) DNA ≥12 months in HBeAg-positive patients or undetectable HBV DNA ≥36 months in HBeAg-negative patients) were randomised 2:1 to stop or continue NA therapy for 72 weeks. Sustained disease remission (HBeAg negative, HBV DNA <2000 IU/mL and normal alanine aminotransferase (ALT)) was evaluated at 72 weeks after stopping NA therapy.ResultsAmong 67 enrolled patients, sustained disease remission was observed in 13/45 (29%) stop versus 18/22 (82%) continue patients. Hepatitis B surface antigen (HBsAg) loss occurred in two patients (one in each group). The median HBsAg decline from randomisation to week 72 was similar in both groups (0.2 (0.0–0.4) vs 0.1 (0.0–0.2) log IU/mL in stop vs continue patients). Among patients who stopped, 15/45 (33%) had virological or biochemical relapse and 17/45 (38%) were retreated according to predefined criteria. A total of 11/18 (61%) pretreatment HBeAg-positive versus 6/27 (22%) HBeAg-negative patients required retreatment (p=0.01). Fourteen (31%) patients developed ALT >10× upper limit of normal (ULN) and another 7 (16%) had ALT >5× ULN. No patients experienced liver decompensation or died.ConclusionThe findings of this prospective study suggest limited benefit of stopping NA therapy in chronic hepatitis B.Trial registration numberNCT01911156.

SUMMARY BackgroundBefore stopping nucleos(t)ide analogue (NA) treatment in chronic hepatitis B (CHB), 6-12 months of consolidation therapy is recommended.

Background & Aims Chronic hepatitis B virus (HBV) infection is an important cause of cirrhosis and hepatocellular carcinoma worldwide; populations that migrate to the US and Canada might be disproportionately affected. The Hepatitis B Research Network (HBRN) is a cooperative network of investigators from the United States and Canada, created to facilitate clinical, therapeutic, and translational research in adults and children with hepatitis B. We describe the structure of the network and baseline characteristics of adults with hepatitis B enrolled in the network. Methods The HBRN collected data on clinical characteristics of 1625 adults with chronic HBV infection who are not receiving antiviral therapy from 21 clinical centers in North America. Results Half of the subjects in the HBRN are male, and the mean age is 42 years; 72% are Asian, 15% are Black, and 11% are White, with 82% born outside of North America. The most common HBV genotype was B (39%); 745 of subjects were negative for the hepatitis B e antigen. The median serum level of HBV DNA when the study began was 3.6 log10 IU/mL; 68% of male subjects and 67% of female subjects had levels of alanine aminotransferase above the normal range. Conclusions The HBRN cohort will be used to address important clinical and therapeutic questions for North Americans infected with chronic HBV and to guide health policies on HBV prevention and management in North America.

Patient misconceptions that severe liver disease due to hepatitis B infection is symptomatic may factor into the unwillingness to spare the time and undergo the inconvenience associated with regular medical follow-up. Implementation of programs that increase awareness of the silent progression of CHB infection and provide culturally responsive clinics, better able to work within patients' time constraints may improve Chinese patients' access to health care.
