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

Dis Markers. 2012;33(6):309-12. doi: 10.3233/DMA-2012-00935.

Abstract

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. gondii antibodies and without TCR) were studied.

Results: The HLA-B35 was significantly increased in TRC group (p=0.0038).

Conclusion: The presence of HLA-B35 may simultaneously predispose to progression to AIDS and TRC.
