Probiotic yogurt consumption may improve gastrointestinal symptoms, productivity, and nutritional intake of people living with human immunodeficiency virus in Mwanza, Tanzania.

The gut-associated lymphoid tissue is a major site of human immunodeficiency virus (HIV) activity and significantly influences disease prognosis. Reducing immune activation due to gastroenteritis may thus help slow disease progression. Probiotic microorganisms have considerable immunomodulatory effects at the level of the gut-associated lymphoid tissue.

Probiotic yogurt consumption is associated with an increase of CD4 count among people living with HIV/AIDS.

Aim: To evaluate the long term effect of yogurt supplemented with Lactobacillus rhamnosus Fiti on the immune function (CD4 count) of people living with HIV/AIDS.

Background: Gastrointestinal infections and the leakage of microbial products from the gut have a profound impact on the deterioration of the immune system among people living with HIV/AIDS. Among persons not infected with the virus, probiotics can prevent gastrointestinal infections and restore an effective gut barrier, suggesting they might have a beneficial effect on the immune function of people living with HIV/AIDS.
