Acute hepatitis B; Acute hepatitis C; Acute hepatitis D – this is a superinfection with the delta-agent in a patient already infected with hepatitis B; Acute hepatitis E; Chronic viral hepatitis; Other viral hepatitis viruses may exist but their relation to the disease is not firmly established like the previous ones (hepatitis F, GB virus C ...
Liver transplantation is sometimes recommended for cases of cirrhosis or hepatocellular carcinoma. [4] Hepatitis B infection has been preventable by vaccination since 1982. [4] [12] As of 2022, the hepatitis B vaccine is between 98% and 100% effective in preventing infection. [1]
The time between hepatitis B infection and development into HCC can be years, even decades, but from diagnosis of HCC to death, the average survival period is only 5.9 months according to one Chinese study during the 1970-80s, or 3 months (median survival time) in sub-Saharan Africa according to Manson's textbook of tropical diseases. HCC is ...
[7] [10] In 2018, it occurred in 841,000 people and resulted in 782,000 deaths globally. [7] Higher rates of liver cancer occur where hepatitis B and C are common, including Asia and sub-Saharan Africa. [3] Males are more often affected with hepatocellular carcinoma (HCC) than females. [3] Diagnosis is most frequent among those 55 to 65 years ...
Viral hepatitis is liver inflammation due to a viral infection. [1] [2] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.
