PapilloV: Human Papillomavirus (HPV) infection and Cervical lesions in HIV infected women in Thailand: a prospective study
In Thailand, cervical cancer it is the second most common cancer among women and causes more than 5,000 deaths each year. HIV infected women are more at risk of HPV infection and more susceptible to develop cervical lesions and ultimately cancer..
Human Papilloma Virus (HPV) infection has been identified as the main risk factor for the development of cervical cancer. Among more than 100 HPV described in the literature, 13 are considered at high risk (HR-HPV) by WHO, especially HPV 16 and 18. Those two genotypes account for more than 70% of cervical cancers worldwide.
The main objectives of the PapilloV study among HIV-infected women in Thailand are to:
From 2012 to 2013, the PapilloV study enrolled 829 HIV-infected women in 24 hospitals throughout Thailand. Women underwent HPV and pap-smear test yearly. In case of abnormal pap-smear or in the presence of HPV-HR, women were further referred for a colposcopy and cervical biopsy if indicated and received appropriate treatment if necessary.
The study is now completed with 78% of the 829 women recruited followed up until the end of the study, and 90% women who underwent at least two visits.

The analysis of the follow-up in terms of incidence, persistence and clearance of HR-HPV infections and cervical lesions are ongoing. They will provide important information to policy makers in terms of screening strategies and potential benefits of HPV vaccine implementation.
