New UCLA-led research suggests certain gut bacteria-including one that is essential for a healthy gut microbiome-differ between people who go on to acquire HIV infection compared to those who have not become infected.
The researchers wanted to get a better understanding of when following HIV infection these changes begin to take place. To this end, they examined gut microbiome samples from 27 men who have sex with men that were collected both before and after they became infected. They then compared those samples with 28 men who were at similar behavioral risk for infection but did not have HIV.
The samples came from the UCLA-led Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO), a resource and data center for millions of pieces of research, lab samples, statistics and other data aimed at boosting investigations into the effects of substance abuse on HIV/AIDS.
The researchers found that during the first year there was very little change in the infected men's gut bacteria. They found, however, that the men who acquired HIV had pre-existing differences in gut bacteria, even before they became infected, compared with their uninfected counterparts.
