Effect of intake of probiotics and probiotic fermented foods on clinical outcomes among people living with HIV: A systematic review and meta-analysis.

Objective: The objective of the study was to determine the effect of probiotics and of probiotic-fermented foods on CD4 T-cell count, viral load, anaemia and body mass index (BMI) among people living with HIV (PLHIV).

Methods: In this article, we systematically reviewed the evidence on the influence of probiotic supplementation on CD4 lymphocyte count, viral load and anaemia among PLHIV on highly active antiretroviral therapy (HAART) and those who were HAART-naive. Medical literature databases identified randomised trials and pre-post studies of probiotic supplementation and HIV-related outcomes, and random effects meta-analysis was conducted.
