Attenuation of immune activation in an open-label clinical trial for HIV-AIDS using a polyherbal formulation.

ABSTRACT: To explain a stable clinical outcome observed in a previous pilot clinical trial using a polyherbal formulation (PHF) for HIV-AIDS, we, in the present study, evaluated the T cell functions from fresh and stored blood samples. In three clinical groups-the anti-retroviral therapy, PHF and control arms-we compared the circulating levels of lipopolysaccharide, LPS-binding protein, soluble CD14, aspartate transaminase (AST) and alanine transaminase (ALT). Additionally, we evaluated the expression of T cell markers and gag-specific immune responses. The PHF treatment significantly reduced the levels of sCD14, AST and ALT. In a cross-sectional analysis at 30 months post-treatment, in comparison to the control group, the PHF arm showed significantly low per-cell expression of PD1, CD95 and HLA-DR.
