Susceptibility to toxoplasmic retinochoroiditis is associated with HLA alleles reported to be implicated with rapid progression to AIDS.

Background/aims: The frequency of HLA markers associated with rapid progression to AIDS was evaluated in Brazilian patients with AIDS exhibiting or not toxoplasmic retinochoroiditis (TRC).

Methods: 98 AIDS patients (25 with TRC, 43 with anti-T. gondii antibodies but without TCR, and 30 without anti-T.

[Greater survival among patients with immunogenetic markers of rapid progression to AIDS: subsidies for nursing care].

This study sought subsidies for improving nursing care programs for AIDS patients and aimed to verify the influence of changes in sexual behavior, including the adoption of safe sex practices, associated with the survival of AIDS patients with immunogenetic markers of rapid disease progression. 27 AIDS patients were interviewed, with genetic predisposition to rapid progression to AIDS. Genes were typified through the polymerase chain reaction.
