== Clinical Summary ==
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.
