How mouth and other microbes affect Kaposi’s sarcoma in people with HIV

Impact of microbiota on AIDS-Kaposi’s sarcoma development and therapy

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11146551

The team will see whether specific bacteria and microbiome changes change inflammation and influence Kaposi’s sarcoma in people living with HIV, with attention to affected African populations.

What this research studies

If I join, researchers would collect samples such as oral swabs and blood to compare the microbes found in people with and without AIDS-related Kaposi’s sarcoma. They will analyze microbial diversity and specific bacteria linked to inflammation and viral activity. The team will use lab and animal models to test how bacterial products change KSHV-related tumor growth and response to therapy. The goal is to find microbial markers and bacterial-driven mechanisms that could point to new treatments or ways to predict outcomes.

Who could benefit from this research

Good fit: Adults living with HIV—particularly those with current or prior Kaposi’s sarcoma or who are at high risk for KS (including underserved African populations)—would be the ideal candidates.

Not a fit: People without HIV, people whose cancers are unrelated to KSHV, or those unable or unwilling to provide oral or blood samples are unlikely to benefit directly from this project.

Why it matters

Potential benefit: This work could lead to new tests that predict KS risk or new treatments that target bacteria-driven inflammation to improve outcomes for people with HIV and KS.

How similar studies have performed: Prior lab and animal studies and emerging clinical microbiome research support the idea that bacteria can influence cancer and inflammation, but applying these findings directly to AIDS-KS in patients is relatively new.
