Perinatal route of transmission of human papillomavirus (HPV) has been demonstrated in several small studies. We designed a large prospective cohort study (HERITAGE) to better understand perinatal HPV. The objective of this article is to present the study design and preliminary data. In the first phase of the study, we recruited 167 women in Montreal, Canada, during the first trimester of pregnancy. An additional 850 are currently being recruited in the ongoing phase. Cervicovaginal samples were obtained from mothers in the first trimester and tested for HPV DNA from 36 mucosal genotypes (and repeated in the third trimester for HPV-positive mothers). Placental samples were also taken for HPV DNA testing. Conjunctival, oral, pharyngeal and genital samples were collected for HPV DNA testing in children of HPV-positive mothers at every 3–6 months from birth until 2 years of age. Blood samples were collected in mother and children for HPV serology testing. We found a high prevalence of HPV in pregnant women (45%[95%CI:37–53%]) and in placentas (14%[8–21%]). The proportion of HPV positivity (any site) among children at birth/3-months was 11%[5–22%]. HPV was detected in children in multiple sites including the conjunctiva (5%[10–14%]). The ongoing HERITAGE cohort will help provide a better understanding of perinatal HPV. Keywords: Human papillomavirus (HPV), Perinatal transmission, Pregnancy, Placenta, Children, Persistence |
