About
Refractory hepatitis B is to point to although standard application nucleoside (acid) analogue treatment undertakes primary treatment and two strengthen treatment, but existence is persistent viremia. Currently, there is no consensus on salvage therapy for patients who remain virus-positive after a second round of antiviral therapy. This is the first multicenter, prospective, parallel controlled, open-label cohort study to compare the efficacy and safety of TDF/TAF combined with ETV1.0mg regimen versus continuation of the original regimen in the treatment of refractory hepatitis B.
Full description
Refractory sex hepatitis B is to point to although standard application nucleoside (acid) analogue treatment undertakes first treat and 2 strengthen treat cure, but existence is persistent viraemia. These patients have active liver inflammation and are at high risk for progression to cirrhosis or primary liver cancer due to persistent virus-positive symptoms. Therefore, it is of great significance to find an effective antiviral program for refractory hepatitis B to reduce the fatality rate of hepatitis B in China. At present, the guidelines recommend that patients with drug resistance to Entecavir (ETV) be treated with tenofovir fumarate (TDF) or propofol tenofovir fumarate (TAF), and clinical studies in China have confirmed that increased dosage of entecavir to 1.0mg can be used as the treatment of drug resistance to entecavir. TDF and TAF resistant patients can be treated with entecavir 0.5mg. However, currently there is no consensus on salvage treatment for patients who remain virus-positive after a second round of antiviral therapy. Previous studies have shown that TDF/TAF combined with ETV 1.0mg as a rescue regimen has no obvious adverse drug reactions. This is the first multicenter, prospective, parallel controlled, open-label cohort study to compare the efficacy and safety of TDF/TAF combined with ETV 1.0mg regimen versus continuation of the original regimen in the treatment of refractory hepatitis B. Meanwhile, long-term outcomes of refractory hepatitis B patients, such as survival, cirrhosis and primary liver cancer, were observed. In addition, the effects of refractory hepatitis B virus strain, host and other clinical characteristics on the antiviral efficacy of nucleoside (acid) analogue were compared with those of patients with initial treatment and secondary enhancement of nucleoside (acid) analogue response. The results of this study are expected to provide a new perspective for the treatment of refractory hepatitis B and provide direct evidence for the formulation of guidelines for the diagnosis and treatment of chronic hepatitis B in China and even internationally.
