  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.

Further study details as provided by Karolinska Institutet:

Primary Outcome Measures:
  • 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).


Secondary Outcome Measures:
  • 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).



Other Outcome Measures:
  • Interim analysis [ Designated as safety issue: Yes ]
    An interim analysis will be performed after approx. 75-100 patients have been included into the study.
