摘要

Purpose of Review

This review discusses recent advances in understanding the mechanisms of CNS HIV invasion and persistence and examines how these processes relate to the neurologic complications of HIV.

Recent Findings

Recent studies have provided compelling evidence that HIV can persist within CNS macrophages and microglia despite long-term suppressive ART, supporting the existence of a CNS reservoir. Updates to treatment of neurosymptomatic CSF HIV RNA escape include evaluation of CNS-specific drug resistance patterns and ART optimization. Evaluation of cognitive symtpoms in persons with HIV should include a comprehensive medical and neurologic evaluation, cessation of Efavirenz, and evaluation of HIV disease activity and immune dysregulation. Novel HIV cure strategies, including shock-and-kill approaches, block-and-lock strategies, and broadly neutralizing antibodies have highlighted the importance of understanding CNS reservoir dynamics and potential neurotoxicity when designing HIV cure strategies.

Summary

HIV enters the CNS during early infection and may establish a persistent viral reservoir. CNS HIV persistence has important clinical implications, including symptomatic CSF HIV RNA escape and cognitive dysfunction, and may represent a barrier to HIV cure.
