Does Vemlidy cure hepatitis B?
Vemlidy is a prescription antiviral medicine that prevents the hepatitis B virus from multiplying in your body. Vemlidy is used to treat patients with chronic hepatitis B infection in adults with compensated liver disease. Vemlidy may lower the amount of HBV in your body and may improve the condition of your liver.
Can HBsAg become negative after treatment?
Patients who become HBsAg negative and develop antibody to HBsAg (anti-HBs) are diagnosed as having resolved hepatitis B [3,4]. This is an uncommon phenomenon in chronic HBV infection. During stage HBV DNA may still be detectable by PCR in serum and more often in the liver.
Can chronic hepatitis B positive become negative?
The hepatitis B e-antigen test result is often used to monitor the effectiveness of many hepatitis B drug therapies that aim to change a chronically infected person's e-antigen status from “positive” to “negative.” By achieving a “negative” e-antigen result, this means that the hepatitis B drug successfully stopped or ...
Can tenofovir cure chronic hepatitis B?
Tenofovir will not cure hepatitis B and may not prevent complications of chronic hepatitis B such as cirrhosis of the liver or liver cancer. Tenofovir may not prevent the spread of hepatitis B to other people.
When does HBsAg become negative?
About half of patients will no longer be infectious by 7 weeks after onset of symptoms, and all patients who do not remain chronically infected will be HBsAg-negative by 15 weeks after onset of symptoms (12).
Is HBsAg positive in chronic hepatitis B?
A protein on the surface of hepatitis B virus; it can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious. The body normally produces antibodies to HBsAg as part of the normal immune response to infection.
Can chronic hepatitis B be cured totally?
There's no cure for hepatitis B. The good news is it usually goes away by itself in 4 to 8 weeks. More than 9 out of 10 adults who get hepatitis B totally recover. However, about 1 in 20 people who get hepatitis B as adults become “carriers,” which means they have a chronic (long-lasting) hepatitis B infection.
How long can a person with chronic hepatitis B live?
The estimated carrier life expectancy is 71.8 years, as compared to 76.2 years among noncarriers (Figure 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.
How can you tell the difference between acute and chronic hepatitis B?
When a person is first infected with the hepatitis B virus, it is called an "acute infection" (or a new infection). Many people are able to naturally get rid of an acute infection. If the infection persists for more than 6 months, it is considered a “chronic infection.”

How long can I take tenofovir for hepatitis B?
Background: Long-term tenofovir disoproxil fumarate (TDF) treatment for chronic hepatitis B (CHB) is associated with sustained viral suppression and regression of fibrosis and cirrhosis at year 5 (240 weeks) and no TDF resistance through 6 years (288 weeks).
How long is hepatitis B treatment with tenofovir?
