What are the phases of hepatitis B?

What are the phases of hepatitis B?

The entire illness of acute hepatitis B sequentially passes through three phases, namely prodromal phase, icteric phase and convalescence phase. The prodromal phase is characterized by MARKED LOSS OF APPETITE, and other flu‐like symptoms such as low‐grade fever, nausea and vomiting, and lasts for a few days.

What is chronic active hepatitis B?

Chronic active hepatitis, an increasingly frequent liver disease that is characterized by diffuse parenchymal inflammation and hepatic cell necrosis, may be caused by viral hepatitis (most commonly hepatitis C virus), autoimmune disorders, and drug-related liver injury.

What happens if you have chronic hepatitis B?

For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosis — a condition that permanently scars of the liver.

What is the reactivation stage of hepatitis B?

Reactivation of hepatitis B refers to the abrupt increase in hepatitis B virus (HBV) replication in a patient with inactive or resolved hepatitis B. Reactivation can occur spontaneously, but more typically is triggered by immunosuppressive therapy of cancer, autoimmune disease, or organ transplantation.

How long do chronic hepatitis B patients 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 long can you live with chronic hepatitis B?

Does hepatitis B shorten your life?

Among women, chronic HBV infection increases the relative risk of mortality to 1.16 (1.04–1.34), as compared to noncarriers, which is consistent with the findings of previous research. This results in a decrease in life expectancy from 82.0 years in noncarriers to 80.1 years in carriers (Figure ​

Can chronic hepatitis B positive became negative?

Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
