Q

How does acute cholangitis progress?

A

Usually caused by bacteria ascending from its junction with the duodenum (first part of the small intestine). It tends to occur if the bile duct is already partially obstructed by gallstones.

diarrheafatigueloss of appetitemild fevermuscle or joint achesnauseaslight abdominal painvomitingweight lossjaundice

374
Q

What is the epidemiology of viral hepatitis?

A

About 2.3 billion people of the world are infected with one or more of the hepatitis viruses. Viral hepatitis results in around 1.4 million deaths each year, HBV and HCV are responsible for about 90% of these fatalities, whilst the remaining 10% of fatalities are caused by other hepatitis viruses

375
Q

A

> Blood tests: These can detect whether the body is producing antibodies to fight the disease, and they can assess liver function by checking the levels of certain liver proteins and enzymes. > Nucleic acid tests: For hepatitis B and C, an HBV DNA or HCV RNA test can confirm the speed at which the virus is reproducing in the liver, and this will show how active the disease is.> A liver biopsy: This can measure the extent of liver damage and the possibility of cancer.> Paracentesis: Abdominal fluid is extracted and tested, to identify the cause of fluid accumulation.> Elastography: This measures the liver’s stiffness by emitting sound waves.> Surrogate markers: A type of blood test to assess the development of cirrhosis and fibrosis.

A

Unfortunately, not all patients with viral hepatitis recover completely. Five to 10 percent of patients with acute HBV infection and about 75% to 80% of patients with acute HCV infection develop chronic hepatitis. Patients (about 0.5% to 1%) that develop fulminant hepatitis have about an 80% fatality rate.
