HPV infection and bacterial microbiota in the placenta, uterine cervix and oral mucosa.

ABSTRACT: We investigated the association between HPV infection and bacterial microbiota composition in the placenta, uterine cervix and mouth in thirty-nine women. HPV DNA genotyping of 24 types was conducted using Multimetrix^®. Microbiota composition was characterized by 16S rRNA gene sequencing. HPV DNA was detected in 33% of placenta, 23% cervical and 33% oral samples. HPV16 was the most frequent type in all regions. HPV infection was associated with higher microbiota richness (p = 0.032) in the mouth but did not influence microbial diversity or richness in other samples. HPV infection was associated with higher abundance of Lactobacillaceae (p = 0.0036) and Ureaplasma (LDA score > 4.0, p < 0.05) in the placenta, Haemophilus (p = 0.00058) and Peptostreptococcus (p = 0.0069) genus in the cervix and Selenomonas spp. (p = 0.0032) in the mouth compared to HPV negative samples. These data suggest altered bacterial microbiota composition in HPV positive placenta, cervix and mouth. Whether the changes in bacterial microbiota predispose or result from HPV remains to be determined in future studies.

Project description:The oral transmission of HPV and, consequently, the risk of oral cancer has increased in the last years. Oral sex has often been implicated among the risk factors for oral HPV infections, however, there is still no consensus on these topics, nor on the relationship between genital and oral HPV infections. The present study aimed to evaluate the coexistence of papilloma virus, at the levels of the oral and genital mucosa, in women with a histologically confirmed HPV lesions (and a positive HPV test) at the genital level and a negative HPV control group. We also evaluated how some risk factors, such as smoking, the number of partners, age, and sexual habits can influence the possible presence of the virus itself in the oropharynx of the same women. In total, 117 unvaccinated women aged between 18 and 52 were enrolled. We found that the prevalence of oral HPV infection was high among the women with concomitant genital HPV infection (22%) compared to the HPV-negative women (0%), and the estimated odds ratio was 17.36 (95% CI: 1.02, 297.04). In none of the women with oral HPV did we find any relevant clinical lesions. The potential risk factors for HPV infections in the oropharynx and genitals were analyzed based on questionnaire responses. A multivariate analysis showed that genital HPV infections were significantly associated with a number of sexual partners > 10 (OR 138.60, 95% CI: 6.04-3181.30, p < 0.001), but the data also referred to having between 3-5 or 6-10 partners as being significant, as were a high level of education (OR 6.24, 95% CI: 1.67-4.23.26 p = 0.003), a frequency of sexual intercourse >10 (OR 91.67 95% CI: 3.20-2623.52, p = 0.004), oral sex (OR 6.16, 95% CI: 1.22-31.19, p = 0.014), and >20 cigarettes/day (OR 6.09 95% CI: 1.21-30.61, p = 0.014). Furthermore, being "separate" and having multiple sexually transmitted diseases were also significantly associated with genital HPV infection. In contrast, oral HPV infections were significantly associated with women aged 36 to 50 years (OR 27.38, 95% CI: 4.37-171.37; p = 0.000202) and oral sex (OR 95.5, 95% CI: 5.13-1782.75, p = 0.001126).Additionally, being separate, being cohabitant, lifetime sexual partners of >10, 3-5 lifetime sexual partners, <20 years of age, >10 sexual intercourse per month, occasional and regular anal sex, >20 cigarettes per day, a history of sexually transmitted disease (herpes and multiple), and having a history of genital warts were significant. Screening and early diagnosis are considered to be practically unfeasible for this category of cancer, given the lack of visible lesions; the 9-valent HPV vaccine remains the only means that could help to successfully counter the growing incidence of oral squamous cell carcinoma.
