2024 - sluttrapport
Humant papillomavirus (HPV) er et vanlig forekommende virus med omtrent 40 typer som kan infisere kjønnsorganene og infeksjonsraten er høyest hos kvinner i fertil alder. De fleste HPV-infeksjoner går over av seg selv, men noen typer, kjent som høyrisiko (HR) HPV, kan vedvare og føre til forstadier til kreft og kreft i livmorhalsen. Disse vedvarende infeksjonene skyldes blant annet virusets evne til å unngå immunsystemet. Det er i tillegg vist at HPV kan infisere noen celletyper i morkaken, noe som kan påvirke morkakens funksjon og potensielt føre til komplikasjoner under graviditeten. I denne studien har vi hatt som mål å undersøke forekomsten av HPV under graviditet og virusets mulige innvirkning på svangerskapsutfall. Gravide kvinner ble rekruttert i Norge og Sverige fra den multisenter populasjonsbaserte prospektive kohortstudien PreventADALL (Preventing Atopic dermatitis and ALLergies). Urinprøver ble samlet fra 950 kvinner midt i svangerskapet og fra 757 av disse også ved fødsel. Morkake prøver ble også tatt fra 578 kvinner. Prøvene ble undersøkt for spesifikk tilstedeværelse av 28 ulike typer genital HPV. Omfattende sosio-demografiske data ble samlet fra kvinnene via elektroniske spørreskjemaer ved svangerskapsukene 18 og 34, og ulike svangerskapsutfall ble registrert. HPV ble påvist hos 40% av de de 950 undersøkte kvinnene midt i svangerskapet og hos 28% av de 757 kvinnene som også ble undersøkt ved fødsel, med HR-HPV funnet hos henholdsvis 24% og 16%. Faktorer som et kort forhold til barnets far før unnfangelsen (<12 måneder) og alkoholforbruk under graviditeten var knyttet til høyere HPV-forekomst. Vi undersøkte om genital HPV-infeksjoner midt i svangerskapet var assosiert med følgende morkake-assosierte svangerskapskomplikasjoner; høyt blodtrykk og assosierte lidelser i svangerskapet, svangerskapsdiabetes og barn som var små for sin gestasjonsalder. Disse komplikasjonene ble henholdsvis funnet hos 9%, 4% og 7% av kvinnene som ble undersøkt midt i svangerskapet, og hos 3%, 1% og 3% blant de kvinnene som var funnet positive for genital HPV midt i svangerskapet. Det ble ikke funnet noen sammenheng mellom genitale HPV-infeksjoner i graviditeten og disse tre svangerskapsutfallene. HPV-infeksjoner i morkaken ble påvist hos 3% av kvinnene, og hos 8% av de med påvist genital HPV midt i svangerskapet. Høye nivåer av HPV i urin var assosiert med morkake infeksjoner og det var høyt samsvar mellom HPV typene påvist i urin midt i graviditeten, og HPV typene påvist i morkake. Kvinner med kortere forhold til barnets far før unnfangelsen (<3 år) hadde høyere forekomst av morkake-HPV-infeksjon (10%) enn kvinnene som hadde et over 5 år langt forhold til barnets far (1%). Imidlertid ble det ikke funnet noen sammenheng mellom påvist HPV i morkake og morkake-assosierte svangerskapskomplikasjoner. Denne studien har bidratt til økt kunnskap om HPV infeksjoner i svangerskapet og mulige konsekvenser av disse. Vi har vist at genitale HPV infeksjoner er veldig vanlige i graviditeten, men at infeksjoner i morkaken er sjeldne. Vi har også vist at verken genital HPV infeksjon midt i graviditeten eller HPV infeksjoner i morkaken påvist ved fødselen, var assosiert med morkake-assosierte svangerskapskomplikasjoner. Prosjektet er gjennomført i henhold til de opprinnelige målene. PhD kandidaten i prosjektet, Cand Med C. Magdalena Værnesbranden, leverte og fikk godkjent sin avhandling i 2024, med tittel «Human Papillomavirus Infection during Pregnancy: Prevalence and Placental Dysfunction Syndromes» (ISBN: 978-82-348-0563-9). Dato for disputasen er 27.02.2025. Assosiasjonen mellom HPV og livmorhalskreft samt enkelte andre kreftformer er godt kjent. Jenter i 12 års-alder har fått tilbud om HPV vaksinering siden 2009, og 12-årige gutter ble tilbudt vaksinen fra 2018. Vaksinene beskytter primært mot de to mest alvorlige typene HPV16 og 18, men gir en viss grad av kryss beskyttelse mot andre HPV typer. I denne studien ønsket vi å undersøke HPV forekomst i svangerskapet og dens assosiasjon med morkake-assosierte svangerskapsutfall. Dersom en assosiasjon ble funnet ville det kunne bety en enda større mulig effekt av HPV vaksinering på helse utfall. Vi fant imidlertid ingen slik assosiasjon, og det forventes derfor ikke at HPV vaksinering vil ha noen innvirkning på morkake-assosierte svangerskapsutfall. HPV prevalensen er høyest hos kvinner i fertil alder, og med innføring av HPV-testing som primærscreeningstest i livmorhalsprogrammet for hele den screenede populasjonen (kvinner 25-69 år), er det nå mange unge kvinner som får påvist en HPV infeksjon. HPV forekomsten blant de yngre årskullene i screeningsprogrammet er høy, på ca 25%, også blant vaksinerte kvinner. Siden de fleste HPV infeksjoner går over av seg selv er det laget en algoritme der kun de med høyest risiko for cervix dysplasi blir utredet umiddelbart, mens de fleste HPV positive kvinnene, som har normale prøver på cytologi og/eller er positive for ikke-hastende HPV typer, blir henvist til å ta en ny prøve om 1-3 år. For disse kvinnene, samt for helsepersonell med behandlingsansvar for disse og for gravide kvinner generelt, er funnene av denne studien viktige og betryggende.

HPV infection is one of the most common infections of the genital tract in women’s reproductive years. The HiPPiE study addresses the possible role of HPV infection during pregnancy, determined by HPV detection and genotyping in pregnant women at week 18 of gestation (urine) and at birth (urine/placenta), on adverse pregnancy outcomes.About 40 HPV types have been found to infect the mucosa of the genital tract. The peak prevalence of infection is seen in women in their reproductive years. Most infections regress spontaneously, but long-lasting persistent infection with 12 HPV types, classified as high-risk (HR) types, is associated with the development of precancerous and cancerous lesions in the cervix. The mechanism for HPV persistence involves impairment of immunological processes in infected epithelium. We hypothesize that HR-HPV may lead to placental dysfunction in pregnant women and cause adverse pregnancy outcomes. The pregnants women included in the study were recruited from the large multi-center population based prospective cohort PrenventADALL (Preventing Atopic dermatitis and ALLergies) study in Norway and Sweden, from Oslo University Hospital, Østfold Hospital Trust and Karolinska Institute, between December 2014 and October 2016. Urine samples for HPV detection were collected at two time points, mid-gestation and delivery, from 950 and 757 of the pregnant women respectively. Placenta samples, consisting of punch biopsies, were taken from 578 women. Birth data and data from pregnancy (blood pressure, diseases of pregnancy and treatments given during pregnancy) were registered, and all data were curated in 2019. HPV detection on nucleic acid eluates from urine and placenta samples was performed, using a commercial kit that detects, genotypes, and partly quantifies 28 genital HPV types, An in-house protocol was used as well for genotyping from placentas samples. HPV (any of the 28 types detected in the assay) was detected in 38% and 28% of the study cohort at mid-gestation and delivery respectively. The corresponding prevalence for high risk (HR)-HPV was of 24% and 16% respectively, Type-specific HPV persistence from mid-gestation to delivery was of 52%, for both the overall HPV 28 types group, and the HR-HPV. A short pre-conception relationship with the child’s father and alcohol intake during pregnancy were associated with higher HPV prevalence. This study was published in 2021 (Int J Infect Dis 2021 Jul;108:574-581. doi: 10.1016/j.ijid.2021.05.064). In a second study that is sent for peer review, the association between human papillomavirus infections detected in urine samples and adverse pregnancy outcomes was investigated. In the general pregnant population in PreventADALL with an overall low prevalence of adverse outcomes, there was no evidence for an association of HPV infection at mid-gestation, persisting infection or multiple HPV infections and adverse outcomes. In the third study that is sent for peer review, the prevalence of placental HPV infections, and viral factor at midgestation associated with placental infections, were investigated. In addition, the association between placental HPV and adverse pregnancy outcomes related to placental dysfunction was studied. High viral loads at midgpregnancy were associated with placental HPV infections. No association was found between placental HPV infections and placental dysfunction syndromes. The PhD student has completed all the courses and PhD educational part. Two papers are under peer review,and the PhD student is finalizing her writing of the thesis, that will be submitted by the 1st of April 2024. The PhD student applied UiO for an extension of her PhD period due to delay in progression related to the pandemic situation in 2020-2021, that was granted until 27.08.2025.

HPV infection is one of the most common infections of the genital tract in women’s reproductive years. The HiPPiE study addresses the possible role of HPV infection during pregnancy, determined by HPV detection and genotyping in pregnant women at week 18 of gestation (urine) and at birth (urine/placenta), on adverse pregnancy and neonatal outcomes.About 40 HPV types have been found to infect the mucosa of the genital tract. The peak prevalence of infection is seen in women younger than 25 years of age. Most infections regress spontaneously, but long-lasting persistent infection with 12 HPV types, classified as high-risk (HR) types, is associated with the development of precancerous and cancerous lesions in the cervix.

Urine samples for HPV detection were collected at two time points (mid-gestation and delivery) from 757 pregnant women. Placenta samples were taken for about two third of the women as well and consist of swabs from both sides of the placenta, and 3 punch biopsies. Birth data (gestational age at delivery, mode of delivery, newborn weight/height and health) and data from pregnancy (blood pressure, diseases of pregnancy and treatments given during pregnancy) were registered, and all data were curated in 2019. HPV detection on nucleic acid eluates from urine and placenta samples was performed, using a commercial kit that detects, genotypes, and partly quantifies 28 genital HPV types, An in-house protocol was used for genotyping from placentas samples.

The third study of the PhD student will describe the prevalence of HPV in placenta, investigate association with risk factors, and adverse pregnancy outcomes. All HPV genotype analyses have been performed, and the statistical work is ongoing. The PhD student has completed all the courses and PhD educational part and has started to write her thesis. The PhD student applied UiO for an extension of her PhD period due to delay in progression related to the pandemic situation in 2020-2021, that was granted until 27.08.2025. The PhD student is now working full-time on her research project until July 2023, and submission of her thesis in scheduled for June/July 2023.

The HiPPiE study addresses the possible role of HPV infection during pregnancy, determined by HPV detection and genotyping in pregnant women at week 18 of gestation (urine) and at birth (urine/placenta), on adverse pregnancy and neonatal outcomes.About 40 HPV types have been found to infect the mucosa of the genital tract. The lifetime risk for HPV infection is estimated to 70% with a peak prevalence of the infection seen in women younger than 25 years of age. Most infections regress spontaneously, but long-lasting persistent infection with 12 HPV types, classified as high-risk (HR) types, is associated with the development of precancerous and cancerous lesions in the cervix.

Recruitment of pregnant women in PreventADALL at week 18 of gestation started in December 2014 and ended in October 2016. The last baby was born in April 2017. Urine samples for HPV detection were collected at two time points (week 18 of gestation and at birth) from 757 pregnant women, approximately equally distributed from each of the three recruiting hospitals. Placenta samples were taken from about two third of the women as well, and consist of swabs from both sides of the placenta, and 3 punch biopsies. Birth data, including gestational age at delivery, mode of delivery, newborn weight/height and health, have been registered. Data from pregnancy, including, blood pressure, diseases of pregnancy and treatments given during pregnancy, were registered in 2018/2019, and pregnancy and birth data were curated in 2019 for the whole PreventADALL cohort. HPV detection on nucleic acid eluates from urine samples was performed, using a commercial kit that detects, genotypes, and partly quantifies 28 genital HPV types. HPV (any of the 28 types detected in the assay) was detected in 38% and 28% of the study cohort at mid-gestation and delivery respectively. The corresponding prevalence for HR-HPV was of 24% and 16% respectively, the most prevalent type being HPV16 (6% and 4% at mid-gestation and delivery respectively). Type-specific HPV persistence from mid-gestation to delivery was of 52%, when considering both the overall HPV 28 types group, and the HR-HPV. A short pre-conception relationship with the child’s father and alcohol intake during pregnancy were associated with higher HPV prevalence. This study was published in 2021 (Int J Infect Dis 2021 Jul;108:574-581. doi: 10.1016/j.ijid.2021.05.064. The PhD student has completed all the courses and educational part of her PhD, and is now finalizing the analyses of the relation of prevalence and persistence of HPV in pregnancy with pregnancy and birth outcomes. The third work of the PhD thesis will address the relation between HPV prevalence at mid-gestation and biomarkers of placental function. Due to COVID-19 pandemics with closed schools and day care centers during 2020, as well as numerous quarantine periods in 2021, the PhD student has been delayed a few months in her project.

The lifetime risk for HPV infection is estimated to 70% with a peak prevalence of the infection seen in women younger than 25 years of age. Most infections regress spontaneously, but long-lasting persistent infection with 12-15 HPV types, classified as high-risk (HR) types, is associated with the development of precancerous and cancerous lesions in the cervix. The mechanism for HPV persistence involves impairment of immunological processes in infected epithelium. We hypothesize that HR-HPV may lead to placental dysfunction in pregnant women and cause adverse pregnancy and neonatal outcomes.

Data from pregnancy, including, blood pressure, diseases of pregnancy and treatments given during pregnancy, were registered in 2018/2019, and pregnancy and birth data were curated in 2019 for the whole PreventADALL cohort. DNA extraction from urine samples and HPV analyses, using a commercial kit that detects, genotypes, and partly quantifies 28 genital HPV types, are complete. Our results show a relatively high prevalence of HPV from urine samples in pregnant women, both at week 18 and, to a lesser extent, at birth. Several factors have been identified, that are related to HPV prevalence and persistence in pregnancy, and the PhD candidate has been working with finalizing the first manuscript, that is about to be sent for publication. The PhD student has also been involved in completing the curation of all pregnancy and birth data relevant for the next part of the study, addressing the relation of prevalence and persistence of HPV in pregnancy with pregnancy and birth outcomes. The PhD student has worked with a Statistical Analysis Plan for this part of the study. The PhD student completed the half-way evaluation mid-April 2020. Due to COVID-19 pandemics, and cancellation of all planned HPV conferences, there were no opportunities for the PhD student to present data internationally in 2020. In addition to the above mentioned, due to closed schools and day care centers during 2020, the PhD student has been delayed in her project.

Type-specific persistence from week 18 to birth is related to high-risk types and high viral loads at week 18. The PhD candidate has been involved in curating pregnancy and birth data in 2019, has performed statistical analyses on prevalence and persistence for HPV in pregnant women and associated factors, and has drafted the first paper for publication. Results have been presented at the Eurogin (European Research Organisation on Genital Infection and Neoplasia) 2019-conference as well as the yearly conference for the Norwegian Society of Gynecology and Obstetrics.

Placenta samples have been taken for about two third of the women as well, and consist of swabs from both sides of the placenta, and from 3 punch biopsies. Data from pregnancy and birth data have been registered, including gestastional age at delivery, mode of delivery, newborn health and weight. An application to the Regional Committees for Medical and Health Research Ethics (REK) in this substudy, in addition to the main PreventADALL REK approval, was required, sought for and approved in 2017. DNA extraction from urine samples and HPV analyses, using a commercial kit that detects, genotypes, and partly quantifies 28 genital HPV types, are in progress. Preliminary data show a relatively high prevalence of HPV from urine samples in pregnant women. Currently, the PhD candidate is compiling dataset of variables.
