The ARBRE Study is an observational prospective trial aimed at investigating the impact of the therapy initiation with INTIs on brain outcomes according to the time of therapy initiation. Three study arms are considered: 1) Early treated HIV-1 infected patients (\<3 months since estimated date of infection), 2) Regularly treated HIV-1 infected patients (\>6 months since estimated date of infection), 3) Matched seronegative control group. Study assessments will be performed at baseline, 1 month and 12 months. Study assessments will comprise comprehensive evaluation of brain outcomes. They will include cognitive functioning, neuroimaging parameters, and functional outcomes.
Randomized patients will receive LA CAB+RPV administration in the hospital (standard of care) or out-of- hospital administration every 2 months (M2, M4, M6, M8,M10, M12). Medical visits, rutinary blood tests and pharmacy visits at the hospital of reference will take place every 6 months- at baseline, M1 (if patient has not previously receiving LA CAB+RPV), M6 and M12.

Enrollment
45
Change in Global Cognitive Functioning
The measure used will be NPZ-12 (NeuroPsychological Z-12). Minimum value: -5 Maximum value: +5. Mean: 0. Lower score will represent worse global cognitive functioning; higher score will represent better global cognitive functioning.
Time frame: From Baseline to Week 48
Change in Neuropsychiatric Symptoms
The measure used will be a checklist of symptoms involving the central nervous system. Minimum value: 0; Maximum value: 140. Lower score will represent better neuropsychiatric status; higher score will represent worse neuropsychiatric status.
Time frame: From Baseline to Week 48
Change in Daily Living Functioning
Daily living functioning will be measured by a self-reported scale indicating daily living areas impaired. Minimum score: 0; Maximum score: 13. A lower score will represent better daily functioning; a higher score will represent worse daily functioning.
Time frame: From Baseline to Week 48
Change in Depressive Symptoms
Depressive symptoms will be measured by a self-reported scale that will assess depressive symptoms. Minimum score: 0; Maximum score: 21. A lower score will represent better depressive status; a higher score will represent worse depressive status.
Time frame: From baseline to week 48
Change in Anxiety Symptoms
Anxiety symptoms will be measured by a self-reported scale that will assess anxiety symptoms. Minimum score: 0; Maximum score: 21. A lower score will represent better anxiety status; a higher score will represent worse anxiety status.
Time frame: From Baseline to Week 48
Change in Daily Perceived Stress
Perceived stress will be measured by a self-reported scale that will assess daily symptoms of perceived stress. Minimum score: 0; Maximum score: 40. A lower score will represent better perceived stress status; a higher score will represent worse perceived stress status.
Time frame: From baseline to week 48
Change in Quality of Life
Quality of life will be measured by a self-reported scale that will assess global quality of life. Minimum score: 1; Maximum score: 4. A lower score will represent worse quality of life; a higher score will represent better quality of life.
Time frame: From Baseline to Week 48
Change in Neuroimaging Markers
Neuroimaging markers will be assessed by 3T magnetic resonance imaging (MRI). The specific markers will be caudate nucleus, ventral striatum/nucleus accumbens, putamen, pallidum, thalamus, dorsomedial, dorsolateral, cingulate, ventromedial, medial orbitofrontal, and lateral orbitofrontal cortex. The outcome will be based on change in any of them.
Time frame: From Baseline to Week 48
