title: Reactivation of hepatitis b after transplantation operations.
abstract: Surveillance of the staff and patients at the Cambridge Transplant and Dialysis Unit for hepatitis-B infection since 1968 has revealed the onset of antigenaemia in 6 patients in eight years. When the first serum of each patient admitted was examined for anti-HBc antibody, 23 of 380 (6-1%) patients were found positive. Since the presence of anti-HBc is taken to be evidence of previous infection, the occurence of antigenaemia in 3 of the positives when they were immunosuppressed after transplantation is believed to be due to reactivation of latent infection. This is a new factor to be considered in the control of hepatitis B after transplantation;
