Brief summary
The aim with this study is to provide immunotherapy with vitamin D and phenylbutyrate to treatment-naive HIV infected patients to induce important antimicrobial defence mechanisms and decreased inflammation.
Interventions
Dose of interventions: 5,000 IU of vitamin D (cholecalciferol tablets) once daily and 500 mg PBA (sodium phenylbutyrate tablets) twice daily for 16 weeks.
Placebo tablets for vitamin D once daily and placebo tablets for PBA (phenylbutyrate) twice daily for 16 weeks.

Eligibility
Inclusion criteria
Adult patients \>18 years not subjected to HAART. HIV-1 infected patients with CD4 T cells counts \>200 cells/ml. Detectable plasma viral loads \>1000 copies/ml.
Exclusion criteria
Patients on HAART or other antimicrobial drugs (including bactrim). Antimicrobial drug treatment in the past month. Patients with medical contra-indication for biopsy such as bleeding tendencies.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| HIV viral load | 0 (baseline) compared to 16 weeks. | Plasma HIV viral load will be used to monitor efficacy of vitamin D and phenylbutyrate treatment among treatment-naïve HIV patients at the time of diagnosis (time point 0) and at 4, 8, 16 and 24 weeks after initiation of antimicrobial treatment with vitamin D and phenylbutyrate. The primary endpoint will be assessed at 16 weeks compared to baseline (time point 0). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical secondary endpoints | 0, 4, 8, 16, 24 weeks. | Overall clinical symptoms. Body mass index (BMI). Mid upper arm circumference (MUAC). |
| Laboratory secondary endpoints | 0, 4, 8, 16, 24 weeks. | HIV viral load (0, 4, 8, 24 weeks). Peripheral CD4/CD8 T cell counts. Plasma levels of vitamin D, LL-37, sCD14, LPS, 16S RNA and cytokine/chemokine profiles. Calprotectin in feces. Inflammation and microbial translocation in colon punch biopsies (0 and 16 weeks). Functional studies of immune cells (PBMCs). |
