Neurocognitive impairment is an important cause of HIV-associated morbidity. The advent of antiretroviral therapy (ART) has shifted the spectrum of HIV-associated cognitive impairment from HIV-associated dementia to milder forms of cognitive impairment. Independent replication of HIV within the central nervous system in those on effective ART with peripheral suppression is a recognised phenomenon known as cerebrospinal fluid (CSF) HIV RNA escape. CSF HIV RNA escape is independently associated with neurocognitive impairment but has also been detected in asymptomatic persons with HIV. The current consensus for management of CSF HIV RNA escape is based on expert opinion rather than empirical evidence. The current evidence suggests having a low threshold to investigate for CSF HIV RNA escape and optimising ART based on resistance profiles. The use of central nervous system (CNS) penetration effectiveness scores is no longer recommended. The evidence for statins, SSRIs, minocycline, lithium and valproate is limited to small-scale studies. There are potential new developments in the form of nanoparticles, Janus Kinase inhibitors and latency reversal agents.

Background: Trafficking of immune cells to the central nervous system is hypothesized to facilitate HIV entry and immune-induced neuronal injury and is mediated by surface proteins such as chemokine receptors and α4 integrin. We longitudinally assessed immune cell activation and surface marker expression in cerebrospinal fluid (CSF) and blood and their relationship with CSF HIV RNA beginning during primary HIV infection (PHI) before and after antiretroviral therapy (ART).
Methods: Longitudinal paired blood and CSF were obtained in ART-naïve PHI (<12 month since infection) participants; some independently initiated ART during follow up.

Central nervous system infections and complications such as meningitis and stroke in immunocompromised patients can be caused by a wide spectrum of pathogens, including bacteria, viruses, parasites, or fungi. This case series first presents a case of a 24-year-old Latino male patient with HIV, cytomegalovirus (CMV) encephalitis, a positive CSF for antigen, and a stroke, who presented to the primary care office with a headache and double vision. With his symptoms now occurring for more than two months without improvement, the patient was sent to the ED for a repeat MRI, where an enlargement of his ventricles compatible with hydrocephalus was observed.

HIV infection alters the human virome, and virome perturbations have been linked to neurocognitive issues in people without HIV. Once thought to be sterile, the cerebrospinal fluid (CSF) hosts a recently discovered virome, presenting an unexplored avenue for understanding brain and mental health in PWH.

Human immunodeficiency virus (HIV) associated motor neuron disease (MND) is very rare. HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection.

A 30-year-old female patient who was 25 weeks pregnant presented to the emergency department with a 1-month history of mild headache and 2 weeks of progressive somnolence and photophobia accompanied by binocular horizontal diplopia and right gaze deviation. The patient also described new neck pain with passive head movements, without neck stiffness. Overall, the pregnancy was uncomplicated, with no high-risk features.
