Post-transfusion HIV infection despite donor screening: a report of three cases.
In August 1996, a blood donation was collected which subsequently infected three patients post-transfusion with HIV 1. The donation itself was originally screened as negative for anti-HIV 1/2 using a sensitive EIA method, but subsequently was shown to contain p24 Ag and HIV RNA by an amplification technique. The proposed introduction of nucleic acid testing of all blood donations in the UK for hepatitis C, hepatitis B and HIV may further reduce the remote risk of further episodes of post-transfusion infection. The infection in the index recipient was detected on routine pre-transplant virological screening but proved difficult to confirm, at a time when she had recently received myeloablative treatment for a haematological malignancy which impaired the immune response. There is a need for continued vigilance in such patients to exclude post-transfusion infection, at a time when natural immunological responses have been impaired by their disease or treatment.
