Long‐term survival of HIV‐infected patients with haemophilia

In France, patients with haemophilia were infected by HIV up until October 1985, with a maximum of seroconversion between 1983 and 1985. There was a progressive development of AIDS in the 1158 infected patients as reported by Health Authorities. By the end of 1992, 32% of the haemophilia population had developed AIDS and 38 had developed clinical or biological symptoms of immunodeficiency. However, 27% had no clinical symptoms and no severe disorder of the immune system. The present study was established to determine factors common to patients with prolonged survival.
