Brief summary
The aim of this prospective, open label study is to check for differences in neuropsychiatric and neurocognitive measurements among patients that will be switched from Atripla to Eviplera among 40 patients.
Detailed description
40 patients on Atripla for at least 12 weeks with undetectable HIV-1 viral load will be randomly assigned to one of two groups in a ratio of 1:1: half of the patients will be switched to Eviplera and half will remain on Atripla. Neuropsychiatric symptoms will be evaluated using specific questionnaires (anxiety and depression scales, sleeping quality scale, etc) and neurocognitive functions will be assessed using standard tests (Trail A and B, memory tests, etc). Patient satisfaction will be assessed using a visual analog scale. Treatment efficacy will be evaluated by measuring the rate of patients with HIV vilral load under 50 copies/mL.

Exclusion criteria
* Subjects with known allergy to one of the study drugs * AIDS defining event diagnosed within 21 days prior to screening * Females who are pregnant or breast feeding * Acute hepatitis diagnosed within 21 days prior to screening * Subjects receiving drug treatment for HCV or subjects anticipated to receive treatment for HCV during the course of the study * Implanted defibrillator or pacemaker * Current alcohol or drug abuse judged by the investigator to potentially interfere with subject adherence * Participation in another interventional trial * Ongoing therapy or anticipated need to initiate drugs during the study that are contraindicated or not recommended for use with study drugs (Carbamazepine, Dexamethasone, Esomeprazole, Fosphenytoin, Lansoprazole, Omeprazole, Oxcarbazepine, Pantoprazole, Phenobarbital, Phenytoin, Piperaquine, Primnidone, Rabeprazole, Rifabutin, Rifampin, Rifapentine, St John's Wort * Any Severe Psychiatric disease that judged by the investigator to potentially interfere with subject adherence to protocol or to drugs or that may interfere with study procedures
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| depression (questionaire) | 12 month | PHQ which is a validated questionaire for depression |
| anxiety (questionaire) | 12 month | STAI which is a validated questionaire for anxiety |
| sleeping quality (questionaire) | 12 month | a validated questionaire |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| color trail test - 2 parts (test result in numbers) | 12 month | a line drawing test which connects points in a certain order. It serves as a general neurocognitive function test |

| Hopkins Verbal Learning Test - Revised (test result in numbers) | 12 month | a validated test for memory testing |
| CD4 cell count (number of cells per mm3) | 12 month | efficacy of treatment in keeping CD4 count from falling after intervention |
| clock drawing test (test result in numbers) | 12 month | a general test for dementia |
| Satisfaction (scale) | 12 month | Visual Analogue Scale (VAS) |
