HIV/AIDS and Sexually Transmitted Diseases


We are studying the effects of GARDASIL 9 vaccination in people with ICL, which stands for idiopathic CD4 T cell lymphocytopenia. People with ICL get more human papillomavirus (HPV)-related diseases than people without ICL. HPV-related diseases include skin and genital warts and a variety of genital and anal precancerous lesions and cancers. These diseases are also more severe and harder to treat in people with ICL.

Natural History, Epidemiology and Pathogenesis of Severe HPV-Related Diseases (NEPTUNE)

We are asking you to join this study because you have had multiple outbreaks of warts and/or lesions caused by human papillomavirus (HPV). Medicine and surgery are not always effective to treat these outbreaks. We want to follow your HPV outbreaks over a long period of time to better understand how HPV infects the body and causes disease.
