Purpose
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.

| Official Title: | Immune Reconstitution in HIV Disease Using Antimicrobial Treatment With Vitamin D and Phenylbutyrate |
- HIV viral load [ Time Frame: 0 (baseline) compared to 16 weeks. ] [ Designated as safety issue: Yes ]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).
- Clinical secondary endpoints [ Time Frame: 0, 4, 8, 16, 24 weeks. ] [ Designated as safety issue: Yes ]
Overall clinical symptoms.
Body mass index (BMI).
Mid upper arm circumference (MUAC).
- Laboratory secondary endpoints [ Time Frame: 0, 4, 8, 16, 24 weeks. ] [ Designated as safety issue: Yes ]
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).
- Interim analysis [ Designated as safety issue: Yes ]An interim analysis will be performed after approx. 75-100 patients have been included into the study.
