Hepatitis B: "Treat all" or "Treat select"

Recompensation in treatment-naïve HBV-related decompensated cirrhosis: a 5-year multi-center observational study comparing patients with ascites and bleeding

BACKGROUND AND AIMS

Recompensation between patients with ascites and bleeding was unknown in treatment-naïve HBV-related decompensated cirrhosis.

METHODS

In this retrospective multi-center study, treatment-naïve HBV-related decompensated patients were enrolled at first decompensating event of ascites and/or variceal bleeding. Further complications and clinical characteristics were collected using standard case report form every 6 months to year-5 of antiviral treatment. Recompensation was defined as maintaining free of decompensation for one year and achieving liver function within Child-Pugh A and/or MELD < 10.

RESULTS

Totally, 170 (170/298, 57.0%) patients in ascites group of 298 (298/383, 77.8%) treatment-naïve decompensated patients and 33 (33/85, 38.8%) in bleeding group of 85 (85/383, 22.2%) patients, achieved recompensation. Ascites group had higher 5-year rate of recompensation than bleeding group (63.3% vs. 46.5%, p = 0.012), respectively. Patients achieving recompensation in ascites group maintained lower rate of second decompensation than these in bleeding group (at year-5: 26.7% vs. 43.3%, p = 0.032). Specifically, recompensated patients in ascites group had predominantly 5-year rate of further ascites (24.0%) and lower rate of further bleeding (6.0%), which differed from the pattern of these in bleeding group, with lower rate of further ascites (16.0%, p = 0.599) and significantly higher rate of further bleeding (33.9%, p < 0.001). Both patients had superior long-term prognosis (death/LT rate at year-5: 0.6% vs. 3.0%, p = 0.196).

CONCLUSION

Ascites patients could achieve higher rate of recompensation through antiviral therapy than bleeding patients. Recompensated patients in ascites group had better prognosis in terms of preventing further bleeding.

A new approach to prevent, diagnose, and treat hepatitis B in Africa

There are 82 million people living with hepatitis B (PLWHB) in the World Health Organization Africa region, where it is the main cause of liver disease. Effective vaccines have been available for over 40 years, yet there are 990,000 new infections annually, due to limited implementation of hepatitis B birth dose vaccination and antenatal tenofovir prophylaxis for highly viraemic women, which could eliminate mother-to-child transmission. Despite effective and cheap antiviral treatment which can suppress hepatitis B virus replication and reduce the risk of hepatocellular carcinoma (HCC), < 2% of PLWHB are diagnosed, and only 0.1% are treated. As a result, PLWHB are frequently diagnosed only when they have already developed decompensated cirrhosis and late-stage HCC, and consequently 80,000 hepatitis B-associated deaths occur each year. Major barriers include complex treatment guidelines which were derived from high-income settings, lack of affordable diagnostics, lack or insufficient domestic funding for hepatitis care, and limited healthcare infrastructure. Current treatment criteria may overlook patients at risk of cirrhosis and HCC. Therefore, expanded and simplified treatment criteria are needed. We advocate for decentralized community treatment programmes, adapted for low-resource and rural settings with limited laboratory infrastructure. We propose a strategy of treat-all except patients fulfilling criteria that suggest low risk of disease progression. Expanded treatment represents a financial challenge requiring concerted action from policy makers, industry, and international donor agencies. It is crucial to accelerate hepatitis B elimination plans, integrate hepatitis B care into existing healthcare programmes, and prioritize longitudinal and implementation research to improve care for PLWHB.
