Autoimmunity and HIV.

PURPOSE OF REVIEW

This review focuses on some of the recent advances in the understanding of HIV immunopathogenesis and the diagnosis and treatment of several autoimmune conditions associated with HIV in the era of potent antiretroviral therapy.

RECENT FINDINGS

Chronic immune activation with progressive immune exhaustion are central features of HIV pathogenesis. The role of self-reactive T cells in the generation and maintenance of this process has recently been described. The understanding of the impact of immune dysregulation on the generation of autoimmune phenomena in HIV infection remains incomplete. The diagnosis of autoimmune diseases in the context of HIV is often difficult due to similarities in clinical presentations and laboratory markers. The antiretroviral therapy-associated immune reconstitution syndrome can present as autoimmune disease.

SUMMARY

The cause, frequency and prognosis of autoimmune conditions associated with HIV infection remain somewhat uncertain. Their management is often empirical with the use of novel immunosuppressive medication.
