The Johns Hopkins NIMH Center for Novel Therapeutics for HIV-associated Cognitive Disorders

The Johns Hopkins NIMH Center comprises an interdisciplinary research team who has pooled their talents to study the nature of HIV-associated neurocognitive disorders (HAND). Their aim is to translate discoveries of the pathophysiological mechanisms into novel therapeutics for HAND.

Neurologic Complications and Considerations in HIV-Infected Persons

Overview: Neurologic complications for HIV-infected persons retain significant prevalence despite an increasingly global use of antiretroviral therapies. This paper will provide a more detailed review of the most common neurologic complications of HIV infection, and will highlight some of the challenges involved with diagnosis, management, and long-term effects. Understanding specific considerations for HIV -associated complications, including the epidemiology, risk factors, medication-adverse effects, and benefits of appropriate management, is vital for all providers caring for those withHIV.

Identification of Putative Biomarkers for HIV-associated Neurocognitive Impairment in the CSF of HIV-infected Patients under cART Therapy Determined by Mass Spectrometry

Overview: We identified and measured proteins in the cerebral spinal fluid (CSF) involved in HIV-associated neurological disorders. Our results suggest that not only a few but possibly a combination of biomarkers that are highly correlated can predict neurocognitive status in HIV-infected patients and might be involved in monocyte or macrophage activation.

Figure 3: Summary of the Frascati criteria for HIV-associated neurocognitive disorders

Overview: Cross-sectional studies show that around half of individuals infected with HIV-1 have some degree of cognitive impairment despite the use of antiretroviral drugs. However, prevalence estimates vary depending on the population and methods used to assess cognitive impairment. Whether asymptomatic patients would benefit from routine screening for cognitive difficulties is unclear and the appropriate screening method and subsequent management is the subject of debate. The extent to which antiretroviral drug distribution and toxicity in the CNS affect clinical decision making is also debated.
