Both constitute reservoirs of infection. HBV infection early in life, particularly via vertical transmission during childbirth, produces a carrier state 90 to 95% of the time. In contrast, only 1 to 10% of adult infections yield a carrier state. Individuals with impaired immunity are more likely to become carriers.</spoiler>

Clinical Summary[edit]

This was a 55-year-old white male with chronic renal failure who acquired hepatitis B virus (HBV) in a renal dialysis unit. Death was the result of multiple disease processes, which included active pulmonary tuberculosis and heart failure due to ischemic heart disease. There were few or no symptoms or signs of hepatitis during life other than seroconversion from negative to HBsAg positive.

At autopsy, the liver was enlarged due primarily to severe passive congestion.

Renal failure is the severe reduction of renal function and often leads to reduced urinary output.

Cirrhosis is a liver disease characterized by necrosis, fibrosis, loss of normal liver architecture, and hyperplastic nodules.

The normal fibrinogen level is 184 to 412 mg/dL.
