Chemokine CC motif ligand 2 (CCL2) is one of the most recognized proinflammatory chemokines, and the expression of CCL2 in the cerebrospinal fluid of patients infected with HIV-1 is significantly higher than that of healthy people. As such, it is seen as an important cause of HIV-associated neurocognitive disorder (HAND). Our previous investigation has confirmed the pathological role of CCL2 in mediating brain damage leading to cognitive dysfunction. Currently, however, research on therapeutic drugs for the central nervous system targeting CCL2 is very limited. Our present study used brain stereotactic technology to induce cognitive impairment in rats by injecting CCL2 (5 ng) into the bilateral hippocampus. To investigate the protective effect and mechanism of Tanshinone IIA (25, 50, 75 mg/kg/d) on CCL2-induced learning memory and cognitive impairment in rats, we performed the Morris water maze (MWM) and novel object recognition tests (NORT) on the rats. The results showed that Tanshinone IIA significantly alleviated CCL2-induced learning memory and cognitive dysfunction. Further studies on the hippocampal tissue of the rats revealed that Tanshinone IIA treatment significantly increased the activity of SOD and GSH-Px while the level of MDA decreased compared to the model group. Additionally, the relative expression of apoptosis-associated genes caspase-3, caspase-8, and caspase-9 and inflammation-associated genes IL-1β and IL-6 in Tanshinone IIA-treated rats was lower than that in model rats. Finally, we confirmed hippocampal neuron loss and apoptosis by Nissl staining and TdT-mediated dUTP Nick end labeling (TUNEL). Taken together, these data imply that Tanshinone IIA can ameliorate CCL2-induced learning memory and cognitive impairment by impacting oxidative stress, inflammation, and apoptosis. Tanshinone IIA may be a potential therapeutic agent for the treatment of HAND.

Although the majority of specialists and researchers in the field of HIV/AIDS are aware and knowledgeable about HIV-associated neurocognitive disorder (HAND) as a condition that affects as much as 50% of people living with HIV/AIDS (PLWH), research has documented that many health care and service providers who work directly with PLWH are either unaware of HAND or believe they do not know enough information about HAND to effectively support their clients experiencing neurocognitive challenges. Based on the findings of a qualitative study that interviewed 33 health care and service providers in HIV/AIDS services to identify and examine their awareness and knowledge on HAND, this article argues for utilizing a combination of Public Health Informatics principles; communication techniques, propagation strategies, and recognized approaches from Implementation and Dissemination Science; and social media and online discussion platforms, in addition to traditional Knowledge Mobilization strategies, to scale up information sharing on HAND among all relevant stakeholders. Increasing information sharing among stakeholders would be an important step to raising awareness and knowledge on HAND, and consequently, improving care, services, and support for PLWH and neurocognitive issues.

Hiv Associated Neurocognitive Disorder

BACKGROUND The introduction of antiretroviral therapy (ART) has led to a drastic fall in the incidence of HIV-associated dementia. However, less severe but limiting forms of HIV-associated neurocognitive disorder (HAND) continues to be prevalent even with the use of ART. Aerobic exercise, a behavioural intervention may be a beneficial and effective complement to ART in the management of HAND. In HIV-negative individuals, aerobic exercise mitigates pathogenic changes similar to those of HAND. OBJECTIVE This protocol describes a randomized clinical trial designed to determine the effect of a 12-week aerobic exercise programme on HAND in Southeastern Nigeria. METHODS A minimum of seventy-six patients diagnosed with HAND will be randomized into aerobic exercise and control groups. Aerobic exercise will be carried out on a stationary bicycle ergometer at moderate intensity, three times a week for 12-weeks. Primary outcomes are neurocognitive performance, CD4-count and viral load. Evaluation of post-exercise neurocognitive performance will be undertaken using reliable neuropsychological tests relevant to PLWHIV, in line with Frascati criteria. Secondary outcomes such as quality of life, and activity limitation and social participation will be assessed using the WHOQOL-Bref, and the Oxford Participation and Activities questionnaire respectively. Data will be subjected to exploratory statistics to test for normality and homogeneity. The effect of the exercise programme on HAND will be analysed using two-way repeated-measures ANOVA, with Bonferroni’s correction. Within-group comparison will be undertaken using paired sampled t-test. RESULTS Enrollment began on 18th January 2021. Recruitment has been completed. The trial is ongoing and will be completed in July 2021 CONCLUSIONS The study will provide valuable information about the effect of aerobic exercise on HAND thus verifying the suitability of aerobic exercise as a complementary therapy for mitigating neurocognitive disorder among PLWHIV. Data from the study will be useful in pursuit of debate on the necessity of a sponsored rehabilitation arm in ART clinics. CLINICALTRIAL The study was registered with the PAN African Trial Registry (PACTR) on the 1stth September 2020. The registration ID is PACTR202009483415745.
