STDs Increase HIV Risk if Exposed
September 11, 2008
People with chlamydia, genital herpes, gonorrhea, and syphilis are at an increased risk for HIV infection if they are exposed to the virus, findings from Dutch researchers show.
Since the infectious agents that cause the STDs thrush and gonorrhea triggered the same inflammatory stimuli in vaginal and skin explants, the authors suggested that the presence of STD-causing infectious agents could cause Langerhans cells to become activated, therefore increasing a person's risk of HIV infection.
In addition, the study data suggests that anti-inflammatory therapies may prove to prevent HIV transmission, the researchers said.
The study, "TNF-alpha and TLR Agonists Increase Susceptibility to HIV-1 Transmission by Human Langerhans Cells Ex Vivo," was published online in the Journal of Clinical Investigation (2008;doi:10.1172/JCI34721).
