Abstract
Sexually transmitted infections (STIs) represent a major cause of morbidity in women and men worldwide. Human Papillomavirus (HPV) infections are among the most prevalent STIs and persistent infections with high-risk HPV (hrHPV) genotypes can cause cervical dysplasia and invasive cervical cancer. The association of other STIs with HPV cervical infection and/or dysplasia has however not yet been fully elucidated. The aim of this study was to assess the prevalence of HPV and other STIs among women presenting with an abnormal cervical cytology. Cervical infections with 28 HPV genotypes and seven other sexually transmitted pathogens were evaluated in 177 women referred for a colposcopy after an abnormal Pap smear. Positivity for at least one hrHPV genotype was shown in 87% of women; HPV 16 was the most prevalent (25.0%), followed by HPV 31 and HPV 51. The overall positivity for other STIs was 49.2%, with Ureaplasma parvum being the most prevalent microrganism (39.0%). Co-infections between hrHPV and other STIs were demonstrated in 17.5% of women; no significant association was demonstrated between multiple infections and the colposcopy findings. This study provides new epidemiological data on the prevalence of cervical infections associated with HPV and seven other common sexually transmitted pathogens in a population of women presenting with an abnormal cervical cytology.
Highlights
Human papillomaviruses (HPVs) are viruses known to be the primary cause of cervical cancer (CC), responsible of approximately 311,000 women’s deaths in 2018 [1]
One hundred and seventy-seven women with an abnormal cervical cytology were recruited at colposcopy
The prevalence rates are influenced by the pre-analytical procedure for sample processing and the HPV test used for viral DNA detection [14,15,16,17]
Summary
Human papillomaviruses (HPVs) are viruses known to be the primary cause of cervical cancer (CC), responsible of approximately 311,000 women’s deaths in 2018 [1]. Even though incidences of CC have decreased in recent decades, a huge burden remains, especially in low-income countries. Nearly 200 different HPV types have been identified, including twelve classified by the International Agency for Research on Cancer (IARC) as oncogenic or “high-risk” HPV types Most HPV infections are benign, persistent infection with one of the carcinogenic hrHPV types is a well-established necessary cause of cervical cancer [3].
