Abstract

AIM: To study the clinical outcome of antiviral therapy in hepatitis B-related decompensated cirrhotic patients.

METHODS: Three hundred and twelve patients with decompensated hepatitis B cirrhosis were evaluated in a prospective cohort. With two years of follow-up, 198 patients in the group receiving antiviral therapy with nucleos(t)ide analogues and 39 patients in the control group without antiviral treatment were analysed.

RESULTS: Among the antiviral treatment patients, 162 had a complete virological response (CVR), and 36 were drug-resistant (DR). The two-year cumulative incidence of hepatocellular carcinoma (HCC) in the DR patients (30.6%) was significantly higher than that in both the CVR patients (4.3%) and the control group (10.3%) (P < 0.001). Among the DR patients in particular, the incidence of HCC was 55.6% (5/9) in those who failed rescue therapy, which was extremely high. The rtA181T mutation was closely associated with rescue therapy failure (P = 0.006). The Child-Pugh scores of the CVR group were significantly decreased compared with the baseline (8.9 ± 2.3 vs 6.0 ± 1.3, P = 0.043).

CONCLUSION: This study showed that antiviral drug resistance increased the risk of HCC in decompensated hepatitis B-related cirrhotic patients, especially in those who failed rescue therapy.

Keywords: Hepatitis B, Decompensated cirrhosis, Nucleos(t)ide analogues, Hepatocellular carcinoma, Drug resistance

Core tip: This study was performed to analyse the clinical data of 312 patients with decompensated hepatitis B cirrhosis in a prospective cohort. These data showed that complete virological response could improve the clinical outcome in decompensated hepatitis B cirrhotic patients. However, clinicians should be aware of the high risk of hepatocellular carcinoma and liver failure in antiviral drug-resistant patients.

INTRODUCTION

Chronic hepatitis B virus (HBV) infection, the main aetiology of liver cirrhosis and hepatocellular carcinoma (HCC), remains a major public health problem worldwide, especially in China[1-3]. Among these patients, the annual incidence of HCC is 2%-5%[3-5]. The most effective method to prevent HCC is to control HBV infection through vaccination[5,6]. In patients already infected with HBV, antiviral therapy remains the best strategy to prevent liver cirrhosis and HCC[6-9]. Major progress in the treatment of chronic hepatitis B has recently been made during the last decade with the development of antiviral drugs, especially nucleos(t)ide analogues (NUCs)[10-12]. Some data supporting the benefit of antiviral therapy on the prevention of HCC in chronic hepatitis B patients have been reported in several randomised controlled trials[12-15]. Nonetheless, antiviral drug resistance is important in determining the success of long-term therapy for chronic hepatitis B patients[16,17]. Based on recent clinical data, the development of resistance to NUCs is associated with an exacerbation of liver disease, including the development of cirrhosis and HCC[16]. In addition, the risk of HCC remains high in HBV-related cirrhosis patients who are treatment-naïve for NUCs[17]. Decompensated cirrhosis is the end stage of the disease and is characterised by high mortality and an extremely high risk of HCC. In HBV-related decompensated cirrhotic patients (DCPs), antiviral therapy using NUCs is recommended according to the 2005 global guidelines[18-20]. However, clinical data regarding the incidence of HCC in HBV-related DCPs with NUC antiviral therapies are limited. Therefore, the aim of the current study was to evaluate the two year outcomes in HBV-related decompensated cirrhotic, treatment-naïve patients using NUCs in a real life practical prospective cohort.
