Objective To analyze the infection status of human papilloma virus (HPV),Ureaplasma urealyticum (UU),Chlamydia trachomatis (CT),and Neisseria gonorrhoeae (NG) in clinical patients.Methods The laboratory specimens including urine,urethral swabs,and cervical swabs from 870 patients from January 1st 2014 to December 31st 2017 were retrospectively analyzed. HPV-DNA was detected by multiplex fluorescent PCR,and the UU-RNA,CT-RNA,and NG-RNA were determined by isothermal nucleic acid amplification. The positive rate of each pathogen and the distribution of positive rate between male and female patients were calculated. The samples were further divided into HPV-positive group and HPV-negative group,and the positive rates of UU-RNA,CT-RNA,and NG-RNA in these two groups were compared.Results The highest positive rate was 53.68%(467/870) for UU-RNA,followed by HPV-DNA [32.41%(282/870) ]and NG-RNA [2.18%(19/870)]. The total positive rate of high-risk (HR)-HPV(subtypes:16,18,31,33,35,39,45,51,52,56,58,59,and 68) [31.52%(209/663)]and UU in female patients [60.93%(404/663)] was significantly higher than that in male patients [17.39%(36/207),30.34%(63/207)](both P<0.001). The male patients had significantly higher CT positive rate in HR-HPV-positive group than in HR-HPV-negative group [22.58%(7/31) vs. 4.54%(8/176)](P<0.001). The female patients had significantly higher CT positive rate in HR-HPV-positive group than in HR-HPV-negative group [10.5%(21/200) vs. 5.61%(26/463)](P=0.024). The UU-RNA positive rate of females in the low-risk (LR)-HPV (subtypes:6 and 11) positive group was significantly higher than that in LR-HPV negative group [70.83%(34/48) vs.2.11%(13/615)](P<0.001).Conclusions Women are more susceptible to HR-HPV and UU infections. HR-HPV-positive patients are more likely to experience CT infection. In contrast,co-infection with UU is more common in LR-HPV-positive females.

Objective: To examine the prevalence and frequencies of human papillomavirus (HPV) genotypes in cervical adenocarcinoma in situ (AIS). Methods: The cases of cervical AIS with concurrent tests of cytology and HPV typing from January 2007 to February 2020 in the Obstetrics and Gynecology Hospital of Fudan University were collected and analyzed. Results: A total of 478 cases of cervical AIS were obtained. The average age of the patients was 39.4 years (range, 19-81 years). The largest age group was 30-39 years (44.8%), followed by 40-49 years (34.7%). Among the 478 patients, 355 underwent high-risk HPV (hrHPV) testing and had a hrHPV-positive rate of 93.8%. Of the 355 patients, 277 also underwent HPV typing and were mostly positive for either or both HPV16 and HPV18 (93.1%), with 55.6% positive for HPV18 and 48.7% positive for HPV16. Among the 478 cases, 266 cases (55.6%) were diagnosed with both AIS and squamous intraepithelial lesion (SIL), while 212 cases (44.4%) were diagnosed with only AIS. Patients infected with HPV16 in the AIS and SIL group significantly outnumbered those in the AIS alone group (P<0.05). Moreover, the rate of positive cytology was 55.9% (167/299 cases), while that of negative cytology was 44.1% (132/299). Among the 109 patients with negative cytology results and co-tested hrHPV, there were 101 HPV-positive cases (92.7%), of which 88 cases were subject to HPV typing and showed an HPV16/18 positive rate of 94.3% (83/88 cases). Conclusions: The combination of HPV typing and cytological screening can maximize the detection rate of cervical AIS, and should continue to be utilized, ideally on a larger scale, in the future.

OBJECTIVETo observe the correlation between human papillomavirus (HPV) infection and cervical lesion among women living in community of Beijing.

METHODSA total of 795 women at age 20-54, living in Zhanlanlu District of Beijing were screened for cervical lesion. Samples of cervical cytology (LCT) and HPV test (hc2) were collected. Colposcopy and biopsy were conducted in women with positive LCT.

RESULTSIn those 795 women, the infection rate of HPV was 14.1% (112/795). In 40 women who were LCT positive 1 early invasive cervical cancer, 4 cervical intra-epithelial neoplasia (CIN3), 3 CIN2 and 7 CIN1 were noticed. In 750 women with negative LCT, 5 CIN1 and 1 low-grade CGIN were diagnosed. In those women who were Cyto(+) and HPV(+), 15 cases (55.6%, 15/27) were diagnosed with > or = CIN1 (including 7 CIN1, 3 CIN2, 4 CIN3 and 1 early invasive cancer).

CONCLUSIONThe risk of cervical lesion significantly increased in women showing positive in cytology and HPV test.

PURPOSE: Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. METHODS: A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Presence of human papilloma viral DNA was detected by in situ hybridization in formalin-fixed paraffin-embedded retinoblastoma tissues using both probes against high- and low risk HPV types. RESULTS: The mean age at diagnosis was 22.0 months (range, 1.1 to 98.0 months), and the mean age at enucleation was 27.8 months (range, 1.5 to 112.7 months) among the 54 patients with retinoblastoma. HPV was not detected in any of the retinoblastoma samples using either high risk or low risk HPV probes. CONCLUSIONS: Our study, being the first study in the Korean population, proposes that HPV infection may have no causal relationship with retinoblastoma in Koreans.

OBJECTIVEInvestigating the distribution of anti-hepatitis E virus (HEV-IgG), anti-human papillomavirus (HPV L1-IgG) and risk factors among female residents in Xinmi County, to explore the influencing factors of HPV vaccine study using HEV vaccinated population as a control.

METHODSA screening study of cervical cancer in Xinmi County, Henan Province, was performed. The information of demographic characteristics and risk factors was collected using standard questionnaire. Nine ml blood was drawn from each woman for enzyme-linked immunosorbent assay to detect HEV-IgG and HPV L1-IgG antibody. Percentile, histogram and binary logistic regression model were used to describe the distribution of risk factors and their correlation to HPV and HEV infection.

RESULTSThe average age of the Xinmi female residents was 47.2 years, their positive rate of HPV L1 antibody was 26.8%, and that of HEV-IgG antibody was 31.0%, both of which were raised with age (P < 0.001). Single factor analysis showed that non-education, low-income and growing age were associated with HEV-IgG antibody positivity, and non-education, lowering ages of first sexual life and growing age were associated with HPV L1-IgG antibody positivity. Multivariable analysis showed that growing age, low-income and work as peasantry were independent risk factors for HEV-IgG antibody positivity, and lowering ages of first sexual life, non-education and growing age were independent risk factors for HPV L1-IgG antibody positivity.

CONCLUSIONSBoth the HEV-IgG and HPV L1-IgG antibodies positive rates increase with age. Age is the common risk factor of HEV-IgG and HPV L1-IgG antibodies in female residents in Xinmi County. The risk factors of HEV-IgG and HPV L1-IgG antibodies have no statistical association, neither cross reaction was found in the HEV-IgG and HPV L1-IgG detection.

ObjectiveTo investigate the association of circumcision with the incidence of human papillomavirus (HPV) infection in men.

METHODSWe collected the samples from the surface of the coronal sulcus, glans penis, penile shaft and scrotum of 351 males examined for HPV infection in our hospital from January 2016 to August 2017, of whom 118 had received circumcision while the other 233 had not. We compared the incidence rate of HPV infection between the circumcision and non-circumcision groups and analyzed the association of the age of circumcision with the incidence of HPV infection.

RESULTSHPV infection was found in 135 (38.46%) of the males, 29 (24.58%) in the circumcision group and 106 (45.49%) in the non-circumcision group, significantly lower in the former than in the latter (χ² = 14.48, P < 0.01). The incidence rate of HPV infection was also remarkably lower in the males circumcised at ≤17 years (13.16% ［5/38］) than in those circumcised at >17 years of age (30.0% ［24/80］) (χ² = 3.942, P = 0.047).

CONCLUSIONSMale circumcision helps reduce the incidence rate of HPV infection in men and earlier surgery may achieve even better effect.

AIMTo investigate whether urine is a good medium for screening and whether there is a correlation between the amount of extracted DNA and human papillomavirus (HPV)-positivity.

METHODSIn the present study, 30 first-voided urine (FVU) specimens and 20 urethroglandular swabs using cervex-brushes from male partners of HPV-positive patients, and 31 FVU specimens and 100 liquid-based cervix cytology leftovers sampled with cervix-brushes from HPV-positive women were examined for the presence of beta-globin. Oncogenic HPV were detected using type-specific PCR.

RESULTSbeta-globin was found in all the brushed samples, whereas it was found in only 68.9% of the FVU specimens. HPV-PCR was positive in 60.0% of the male brushes, in 29% of the female brushes and in 0% of the male FVU specimens. DNA concentration was, respectively, 0.9998 ng/microL, 37.0598 ng/microL and 0.0207 ng/microL.

CONCLUSIONUrine is not a good tool for HPV detection, probably because the low DNA concentration reflects a low amount of collected cells. beta-globin is measurable in FVU by real time quantitative PCR, but the DNA concentration is lower compared to brush sampling for both genders. beta-globin-positivity of urethral and cervical swabs is 100%, showing a higher mean concentration of DNA, leading to a higher detection rate of HPV. This is the first article linking DNA-concentration to the presence of HPV.
