A renal transplant patient became a carrier of HBs Ag within four weeks of a successful transplant. The level of antigenaemia was extremely high, and approximately 3% of the particles were 42 nm Dane particles, although the anti-HBe was present from at least 20 months after transplant. After four years the antigenaemia declined to a low level, and five years later HBs Ag became undetectable for...
