HPV Associated With Increased Risk of HIV in Men
A study of 2,519 Kenyan men conducted by researchers at the University of North Carolina revealed that infection with the human papillomavirus (HPV) was associated with a higher subsequent risk of infection with HIV, a precursor to AIDS.
The study, published online by the journal AIDS, was authored by Jennifer Smith, PhD, MPH, research associate professor with the Gillings School of Global Public Health and member of the UNC Lineberger Comprehensive Cancer Center, and Anne Rositch, PHD, MSPH, assistant professor with the University of Maryland School of Medicine.
“These data from Kenya add to a mounting evidence showing a higher risk of HIV acquisition among individuals with genital HPV infections,” said Smith.
Men in the study with at least one occurrence of HPV infection faced double the risk of acquiring HIV, and those with three or more HPV infections had more than three times the risk of developing HIV. This pattern was consistent in both circumcised and uncircumcised men.
While the links between HPV infection and HIV in women has been widely studied, data about similar associations among men is limited. HIV is the leading cause of death in Kenya. While sub-Saharan Africa leads the world in HIV infections and death, the worldwide impact of the virus claims between 1.5 and 1.9 million people each year, according to the World Health Organization.
“It will be important to link future vaccination status with HIV incidence databases on the population-level to examine the impact of HPV vaccination coverage on the incidence of new HIV infections,” said Smith.
