Abstract
Background:
The aim of this study was to review the clinical data on the effectiveness of
the pharmacotherapy of HIV-associated neurocognitive disorders (HANDs).
Methods:
A literature search of PubMed was performed (from January
1996 to October 2018) using the terms: ‘HIV-associated neurocognitive
disorders’, ‘HIV-associated dementia’, ‘mild neurocognitive disorder (MND)’,
‘asymptomatic neurocognitive impairment (ANI)’, ‘adjuvant therapies’,
‘antiretroviral treatment (cART)’, ‘neurotoxicity’, ‘cART intensification’,
‘fluid markers’, ‘cerebrospinal fluid’, ‘protease inhibitors’,
‘nonnucleoside reverse transcriptase inhibitor’, ‘nucleoside reverse
transcriptase inhibitors’, and ‘integrase strand transfer inhibitors’.
Additional references were identified from a review of literature citations.
All English language clinical studies of adjunctive therapies and neuronal
markers were selected in order to evaluate a closer relationship between the
early involvement and the onset of cognitive decline. We identified 407
relevant studies, of which 248 were excluded based on abstract analysis.
Finally, we analyzed 35 articles, organizing the results by cART, adjuvant
and neuronal markers (total of 7716 participants).
Results:
It is important to inform clinicians about the importance of accurate
phenotyping of HIV patients, incorporating an array of markers relevant to
HAND pathophysiology, in order to assess the individual’s risk and potential
response to future personalized antiretroviral treatment
Conclusion:
So far, no clinical trials of HAND therapies are effective beyond optimal
suppression of HIV replication in the central nervous system. Combination of
validated neuronal markers should be used to distinguish between milder HAND
subtypes and improve efficiency of clinical trials, after strict control of
confounders.
