Abstract Background High-risk human papilloma virus (hrHPV) is the main causal factor of cervical precancer and cancer when persistent infection is left untreated. Previous studies have confirmed the vaginal microbiota is associated with HPV infection and the development of cervical lesions. The microbiota at different parts of the female genital tract is closely related but different from each other. To analyze the distinction between the vaginal and cervical microbiota of hrHPV(+) women in China, one hundred subjects were recruited, including 10 patients with HPV16/18(+) and cervical carcinoma, 38 patients with HPV16/18(+) but no cervical carcinoma, 32 patients with other hrHPV(+) and 20 healthy controls with HPV(−). Vaginal and cervical microbiota were separately tested through next-generation sequencing (NGS) targeting the variable region (V3-V4) of the bacterial ribosome 16S rRNA gene. Results HrHPV(+) subjects had higher percentages of vaginal douching history (P = 0.001), showed more frequent usage of sanitary pads (P = 0.007), had more sex partners (P = 0.047), were more sexually active (P = 0.025) and more diversed in ways of contraception (P = 0.001). The alpha diversity of the cervical microbiota was higher than that of the vagina. The cervical microbiota consisted of a lower percentage of Firmicutes and a higher percentage of Proteobacteria than the vagina at the phylum level. Sphingomonas, belonging to α-Proteobacteria, was almost below the detection limit in the vagina but accounted for five to 10 % of the bacteria in the hrHPV(−) cervix (P<0.001) and was inversely associated with hrHPV infection (P<0.05). Pseudomonas, belonging to γ-Proteobacteria, could hardly be seen in the normal vagina and shared a small percentage in the normal cervix but was significantly higher in the HPV16/18(+) (P<0.001) and cancerous cervix (P<0.05). No significant difference was shown in the percentage of BV associated anaerobes, like Gardnerella, Prevotella, Atopobium and Sneathia, between the cevix and vigina. Conclusions The proportion of Proteobacteria was significantly higher in the cervical microbiota than that of vagina. The hrHPV infection and cervical cancer was positively associated with Pseudomonas and negatively associated with Sphingomonas. It is of great improtance to deeply explore the cervical microbiota and its function in cervical cacinogenesis.

Abstract Background: High-risk human papilloma virus (hrHPV) is regarded as the main causal factor of cervical precancer and cancer when persistent infection is left untreated. Previous researches have confirmed that the vaginal microbiota was associated with HPV infection and the development of cervical lesions. A very recent study has revealed the microbiota at different parts of the female genital tract was closely related but different from each other. To analyze the distinction between vaginal and cervical microbiota of hrHPV(+) women in China, one hundred subjects were recruited including 20 healthy controls without HPV infection, 32 with other hrHPV(+), 38 with HPV16/18(+) and 10 with cervical carcinoma. Vaginal and cervical microbiota were separately tested through next-generation sequencing technology (NGS) targeting the variable region (V3-V4) of bacterial ribosome 16S rRNA gene. Results: HrHPV(+) subjects tend to be accustomed to vaginal douching (p =0.001), show more frequent usage of sanitary pads (p =0.007), have more sex partners (p =0.047), be more sexually active (p =0.025) and more diversed in ways of contraception (p =0.001). Alpha diversity of cervical microbiota was higher than that of vagina. Cervical microbiota consisted a lower percentage of Firmicutes and a higher percentage of Proteobacteria compared to the vagina at the phylm level. Sphingomonas of α-Proteobacteria was almost below detection limit in the vagina whereas accounted for five to ten percent at hrHPV(-) cervix (P＜0.001) and reversely associated with hrHPV infection (P＜0.05). Pseudomonas of γ-Proteobacteria could hardly be seen in the normal vagina and shared a little bit percentage in the normal cervix, but significantly higher in the HPV16/18 infected (P＜0.001) and cancerous cervix (P＜0.05). BV associated anaerobes like Gardnerella, Prevotella, Atopobium and Sneathia did not exhibit cervical specificity.Conclusions: Cervical microbiota has its uniqueness from that of vagina in bacterial communities presenting a higher proportion of Proteobacteria, of which Pseudomonas is positively while Sphingomonas was negatively associated with hrHPV infection and cervical cancer. It is of great improtance to deeply explore the cervical microbiota of hrHPV infected women.

Objective: Individuals are often infected with multiple genotypes of human papillomavirus (HPV) simultaneously, but the role these infections play in the development of cervical disease is not well established. This study aimed to determine the association of multiple HPV infections with high-risk cervical lesions (hrCLs). Study Design: HPV genotyping was performed on 798 SurePath specimens collected between December 1, 2009, and April 30, 2011. The cases were classified as hrCL (n = 90) or non-hrCL (n = 708) based on cytology diagnoses. The association between hrCL and HPV infection patterns was analyzed. Results: Multiple HPV infections were frequently encountered (38.2%) in the cohort. Increased frequency of hrCLs was associated with a single high-risk HPV (hrHPV) infection. An additive or synergistic effect was not observed for hrCL in multiple HPV infections. The hrCL rates appeared to decrease in various patterns of multiple HPV infections, but the reduction was not statistically significant. Conclusions: Multiple HPV infections are common with no additive or synergistic effect on the development of hrCL. Conversely, reduced hrCL rates were observed in various patterns of multiple HPV infections compared to their single-genotype infection counterparts, suggestive of possible intergenotypic competition or more effective immune response triggered by multiple infections. Further studies in larger cohorts are needed.

High Risk Hpv

Abstract Background: High-risk human papilloma virus (hrHPV) is regarded as the main causal factor of cervical precancer and cancer when persistent infection is left untreated. Previous studies have declared that HPV is associated with microecological environment of lower genital tract but haven’t discriminate vaginal microbiota from that of cervix. Objective: To analyze the distinction between vaginal and cervical microbiota in high-risk HPV(+) Chinese women. Methods: One hundred participants were recruited including 20 healthy women with HPV (-), 32 with other hrHPV (+), 38 subjects with HPV16/18 (+) and 10 with cervical carcinoma, demographics of whom were collected and analyzed. Vaginal and cervical microbiota were separately tested through next-generation sequencing technology (NGS) targeting the variable region (V3-V4) of bacterial ribosome 16S rRNA gene. Results: 1. Analysis of demographics demonstrated that hrHPV infected women tend to be accustomed to vaginal douching (p =0.001), show more frequent usage of sanitary pads (p =0.007), have more sex partners (p =0.047), be more sexually active (p =0.025), have more diverse ways of contraception (p =0.001) and history of vaginitis (p =0.002). 2. NGS identified microbial diversity of cervical microbiota was much higher than that of vagina with significantly increased Proteobacteria and decreased Lactobacillus. Variation of cervical microbiota of hrHPV(+) subjects partly similar to vaginal microbiota but had its unique features. Sphingomonas of α-Proteobacteria, almost invisible in the vagina, was more frequent at normal cervix whereas decreased remarkably at hrHPV(+) cervix. Reversely, γ-Proteobacteria showed a significant positive correlation with HPV16/18 and cervical cancer. BV related anaerobes like Gardnerella, Prevotella, Atopobium and Sneathia showed similar changes in both vaginal and cervical microbiota of hrHPV(+) women and did not exhibit cervical specificity. Conclusions: Cervical microbiota has its uniqueness from that of vagina in bacterial communities presenting a higher proportion of Proteobacteria, of which Sphingomonas is potentially predictive of a health guardian of hrHPV while Pseudomonas the opposite.

Gynecological Malignancy

Cervical cancer is the second most common gynecological malignancy in the world. Human papilloma virus (HPV) infection is the leading ethiologic agent in the development of premalignant and malignant cervical diseases. HPV is a member of the Papovaviridae family and until now over 100 types have been recognized. There are two types of viral infection: latent and productive. Virus induced oncogenesis is the result of interaction between virus oncoproteins E6 and E7 and tumor supresor host genes p53 and Rb. Many cofactors such as immunosuppression, early sexual relationship, multiple sexual partners, other sexualy transsmited infections and smooking are contributing factors of the precancerous and invasive cervical lesions. According to the oncogenic potential HPV are divided into three groups: low, intermediate and high oncogenic risk viruses. Molecular technics which are used for the virus detection are: In situ hibridisation,, Hybrid capture test and polymerasa chain reaction. Human papilloma virus testing has an important role in the follow up and treatment of women with 'atypical squamous cells of unknown significant' changes in cervical smears and low-grade squamous intraepithelial lesions, changes in punch biopsy.

Protection Against Infection

Human papillomavirus (HPV) is a significant source of morbidity and mortality worldwide. The primary risk factors for aquiring HPV are generally associated with sexual activity.  Evidence suggest that condoms provide some protection against infection and disease progression, but any genital contact is sufficient for HPV transmission.  Having more than one sexual partner often result in HPV infection.  All sexually active adolescents are at high risk for aquiring HPV.  Persistent infection with high-risk HPV types (e.g HPV 16 or 18) is considered necessary for the development cervical cancer.  Most infection are asymptomatic and are efficiently cleared by he immune system.  The lesions that caused by HPV can regress in adolescent and young adult women.  A small percentage of adolescents will develop precancerous lesions that may progress to invasive cervical cancer.  Adolescents should be given appropriate education about HPV and the dangers associated with infection.  Vaccination for HPV infection should be given for presexually active children and adolescents.Key words: human papilloma virus, adolescent, cervical cancer, vaccination.

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections. HPV high risk (HPVHR) were HPV16,18 related with invasive penile carcinomas, and HPV low risk (HPVLR) were HPV6,11 related to anogenital warts. Male infection is usually asymptomatic that it would be explain increasing the incidence of HPV associated cancers. Identification HPV genotype is very important for predicting the development of the diseases, to be benign or malignant cancer. The objective of this study was to identify the genotype of HPV that infect men with anogential warts. This research used 12 biopsy specimens from men patient with anogenital warts at Outpatient clinic of Department Dermatology and Venereology, Dr. Soetomo General Hospital period 2016-2017. The specimens were diagnozed by pathologist and HPV gentoyping was done to detect 40 HPV genotype including HPVHR and HPVLR. The result showed that 58% (7/12) were positive for HPVLR and 42% (5/12) were positive for HPV LR/HR. The genotype HPV that infected men patient with anogenital warts is HPVLR (HPV6,11) and HPVHR (HPV18,51,52,82) with single infection of HPVLR or mutiple infection HPVLR/LR or HPVLR/HR. The infection of HPVHR would be develops to be malignant transformation. It suggested that HPV genotype needs to be checked the for the anogenital warts cases for predicting the development of the diseases.
