To determine the heterosexual spread of human T-cell leukemia virus (HTLV-I) infections, a cohort of 472 individuals with more than 5 heterosexual partners in the 6 months before entry was studied. They were recruited from visitors to the Clinic for Sexually Transmitted Diseases of the Municipal Health Service. Half of the study group was born in the Netherlands, 13% in Surinam or the Dutch Antilles, and 8% in Turkey or Morocco. Seventy percent were involved in commercial sex. Three persons were positive for HTLV-I, with serum antibodies against p19, p24, p28, gp46, and gp61 in Western immunoblot (WIB) and radio-immunoprecipitation assay (RIPA). Two of them originated from Surinam and the third was a Dutch woman. Two other individuals were HIV-positive, 19% had hepatitis B virus (HBV)-markers and 6% Treponema pallidum reacted in the hemagglutination assay (TPHA). It is concluded that HTLV-I circulates in the Surinamese population in Amsterdam and there was no evidence of appreciable heterosexual transmission. 相似文献

A study among heterosexual men and women with multiple sexual partners was carried out to assess the seroprevalence of antibody against hepatitis C virus (HCV). The 468 participants were recruited among visitors to the Clinic for Sexually Transmitted Diseases in Amsterdam. Sera were tested by an enzyme-linked immunosorbent assay (ELISA; Ortho), a recombinant-based immunoblot assay (RIBA; Chiron), and the polymerase chain reaction (PCR). A total of 468 persons were tested, and seven (1.5%) were found ELISA positive. Another 25 (5%) were ELISA indeterminate. Six of the seven ELISA-positive cases were RIBA positive. Further serum samples from five HCV ELISA-positive persons were tested by PCR, and four were found to be positive. The HCV ELISA-positive/RIBA-indeterminate reaction was PCR negative. None of the 17 RIBA-tested sera of the ELISA-indeterminate group yielded a positive result. There was a good correlation between an ELISA optical density/cut-off ratio greater than 2 and a positive RIBA result. The risk factor for HCV appeared to be the type of sexual partner, i.e., belonging to a "high-risk" group for human immunodeficiency virus infection and origin from hepatitis B-endemic countries. It is concluded that HCV may be transmitted through heterosexual contact but probably with low efficiency. 相似文献

This study was undertaken to determine the prevalence and type specific distribution of human papillomavirus (HPV) in women with normal cervical cytology in Kuwait. The study is the first of its type in Kuwait and one of few in the Middle East. The age specific distribution of HPV types was determined in 3,011 ThinPrep samples taken from women seeking routine gynaecological care. ThinPrep samples were screened for HPV DNA by real-time PCR. The type specific distribution of the viruses was determined by PCR-based sequencing. The results showed that HPV DNA was detected in 71 women (2.4%), and 21 different HPV genotypes were detected, comprising eight high-risk (HR) (16, 31, 33, 53, 56, 58, 66, and 73), seven low-risk (LR) (6, 11, 54, 61, 70, 81, and 90), four intermediate-risk (IR) (67, 82, 83, and 84) and HPV 102 and HPV 106. LR HPV types were found in 71.8% of infected samples, HR types in 32.3%, and IR types in 7%. With regard to age, 40.8% of all HPVs were found in women 30-39 years of age, 29.6% in women 40-49 years of age, 19.7% in women over 50 years and 9.9% in women less than 34 years old. The study shows that the prevalence of HPV infection in Kuwait is among the lowest in the world and suggests that HPV vaccine could prevent the development of HPV associated cervical cancer in 1.39% of young females living in Kuwait. However, more extensive population-based studies should be undertaken before implementing HPV vaccination. 相似文献

Male circumcision is associated with a lower risk of penile human papillomavirus (HPV) infection in human immunodeficiency virus (HIV) uninfected men. Few studies have evaluated the role of male circumcision in penile HPV infection in HIV-infected men. The aim of this cross-sectional study was to examine the association between male circumcision and the prevalence of penile HPV infection among HIV-infected men—both men who have sex with men (MSM) and heterosexual men. Samples from 706 consecutive men included in the CARH-MEN cohort (overall 24% circumcised: 26% of MSM, 18% of heterosexual men) were examined by Multiplex-PCR. In the overall group (all HIV-infected men included), the prevalence of any penile HPV infection was 22% in circumcised men and 27% in uncircumcised men (OR = 1.0, 95% CI 0.6–1.6, adjusted analysis). In the circumcised group the overall prevalence of HPV infection was 22% in MSM and 24% in the heterosexual men, whereas in the uncircumcised group the prevalence was 26% and 28%, respectively. The prevalence of high-risk HPV types tended to be lower in the circumcised MSM (14% vs 21%, OR = 0.6, 95% CI 0.3–1.1, p 0.088), but it was similar in the heterosexual men (18% in circumcised vs 20% in uncircumcised). These results suggest that male circumcision may be associated with a lower prevalence of oncogenic high-risk penile HPV infection in HIV-infected MSM. 相似文献

The natural history of type-specific oral infection of human papillomavirus (HPV) was assessed in a cohort of HIV-infected men (538 men who have sex with men (MSM); 195 heterosexuals). Risk factors associated with oral HPV infections were examined. The overall prevalence of HPV was 16%: HPV-16 was the most prevalent type (3.7% MSM; 7.8% heterosexuals). The prevalence of HPV-16 in heterosexuals was associated with CD4 nadir counts <200 cells/μL (ORadjusted = 3.0, 95% CI, 1.4–6.3). The overall incidence of HPV was similar between groups (11%), but the incidence of HPV-16 was higher in heterosexuals (ORadjusted = 3.2, 95% CI, 1.1–9.5). Not only MSM but also HIV-infected heterosexual men are at risk of HPV infection. Regular and careful oral inspection is needed. 相似文献

Genital human papillomavirus (HPV) is the causative agent of cervical cancer and is the most common sexually transmitted infection. Only limited and controversial data are available regarding HPV transmission in male sexual partners of women with cervical intraepithelial neoplasia (CIN). The aim of this study was to investigate the prevalence and the genotype distribution of HPV in penile scrapings of a series of Italian men, who had no visible penile lesions and were partners of women who were affected, or had been affected previously by cervical intraepithelial neoplasia or who were infected with HPV. The concordance of the viral group in the infected partners was determined. A total of 77 penile scrapings were screened for HPV infection by the polymerase chain reaction, while 59 cervicovaginal brushings of their female partners were tested. 35% of evaluable male samples and 64% of female sexual partners were found to be HPV positive. In the 55 simultaneously evaluable couples, a concordance of 45% was found, 11 couples (20%) with both partners being HPV negative and 14 couples (25%) with both partners HPV positive (P=0.001). Six out of the 14 couples (43%), where both partners were HPV positive, harbored the same HPV genotype group. These data, although preliminary, could support further the hypothesis that male HPV infection is more frequent in sexual partners of HPV positive or women with cervical intraepithelial neoplasia indicating that men could represent an important source of HPV transmission between sex partners. 相似文献

This study investigates the distribution of human papillomavirus (HPV) in women with abnormal cervical cytology in Kuwait. Two hundred and ninety‐eight (298) abnormal ThinPreps were taken from women seeking routine gynecological care and screened for HPV DNA by real‐time PCR. HPV genotyping was determined by PCR‐based sequencing. HPV DNA was detected in 152 women (51%), and 29 different HPV genotypes were detected, comprising 16 high‐risk (HR) (16, 18, 31, 33, 35, 39, 45, 51, 53, 56, 58, 59, 66, 68, 73, 97), nine low‐risk (LR) (6, 11, 54, 61, 74, 81, 90, 102, 106), and four intermediate‐risk (IR) (62, 67, 84, 87). HPV16 had the highest prevalence (24.3%), followed by HPV11 (13.8%), HPV66 (11.2%), HPV33 (9.9%), HPV53 (9.2%), HPV81 (9.2%), HPV56 (7.9%) and HPV18 (6.6%). HPV prevalence was 86, 67, and 89% in women with invasive cervical carcinoma (ICC), high‐grade squamous intraepithelial lesion (HSIL) and low‐grade squamous intraepithelial lesion (LSIL), respectively. As for age distribution, 69% of all HPVs were found in women aged 20–29 years, and the HPV incidence rate deceased with increasing age. The proportion of single infections decreased as the severity of the cytological diagnosis increased, while the proportion of multiple infections increased. This study is the first of its type in Kuwait and one of few in the Middle East. The findings are consistent with the hypothesis that HPV infection is the primary cause of cervical neoplasia. They support HPV vaccine research to prevent cervical cancer and efforts to develop HPV DNA diagnostic tests. Diagn. Cytopathol. 2013. © 2011 Wiley Periodicals, Inc. 相似文献

Persistent infection with high-risk (HR) human papillomavirus (HPV) types is necessary for cervical cancer development. However, little is known about the influence of multiple HPV infections on cervical lesion risk. The aim of this study was to evaluate the frequency of single and multiple HPV infections in Portuguese women, and to assess the frequency of multiple infections in cervical intraepithelial neoplasia (CIN). HPV prevalence, type-specific prevalence and extent of multiple infections were assessed in 1057 cervical samples. The Clinical Array HPV assay was used to detect 35 HPV types. According to histological diagnosis, 425 samples were normal, 375 were CIN1, and 257 were CIN2+. HPV status was studied in relation to age and lesion severity. The prevalence of HPV infection was 52.7%; 25.4%, 67.2% and 76.7% were positive for any HPV type in the normal, CIN1 and CIN2+ cases, respectively. Among HPV-positive cases, 32.0% were associated with multiple infections. Among multiple infections, 96.1% harboured HR HPV types and 38.2% HR–low risk (LR) HPV types. Overall, 33 different HPV types (18 HR and 15 LR) were detected. HR HPV types (44.1%) were significantly more prevalent than LR HPV types (8.6%). The most frequent genotype was HPV 16 (25.5%), followed by HPV 31, 53, 66, 58, and 51. Multiple infections showed a significant increase (p 0.005) according to severity of neoplasia, particularly for HR–HR HPV infections (p 0.003). No association between age and multiple HPV infections was observed (p 0.812). However, multiple HR HPV infections were more frequent in women under 30 years of age (35.3%). 相似文献

Cutaneous human papillomavirus (HPV) types are commonly found in normal skin, and some of them have been suspected to play a role in the development of non‐melanoma skin cancer. This present study is divided into three sections, the aims of this study were to examine if certain HPV‐types persist over time and if HPV‐types are shared within families. From the first part of the study, swab samples from foreheads were collected for three longitudinal studies from one family with a newborn baby. Five specific HPV‐types were isolated from the family with a newborn, with HPV‐5 and FA67 being found at various time points and prevalence rates in all four members of the family. Part 2 consisted of a followed up study from two families with a 6 years interval. Six of the family members were found to have at least one of the HPV‐types identified in the family 6 years earlier. Many of the HPV‐types identified were shared within the families studied. Part 3 of this study involved weekly samples from four healthy females for 4 months. Among the four healthy individuals, 11%, 65%, and 56% of the weekly samples were HPV‐DNA positive with one individual HPV‐negative. All specimens were tested for HPV‐DNA by PCR using the broad range HPV‐type primer pair FAP59/64. The positive samples were HPV‐type determined by cloning and sequencing. Specific cutaneous HPV‐types persist over long periods of time in healthy skin in most individuals investigated and certain HPVs are shared between family members. J. Med.

Human papillomavirus (HPV) are distributed widely and persistent infection with high‐risk (HR) HPV is recognized as a necessary cause of cervical cancer. The aim of this study was to evaluate the distribution of different HR‐HPV genotypes in 199 women with cervical pre‐invasive lesions undergoing conservative treatment. A Linear Array HPV Genotyping Test was used to identify individual HPV genotypes in cervical samples. It was observed that the most prevalent HPV genotypes were HPV 16 (52.6%), HPV 51 (13.5%), and HPV 31 (10.9%); HPV 18 was found in 7.3% of the patients. Stratifying the different HPV genotypes according to the severity of the cervical lesion, a strong association between the increasing severity of the histological diagnosis and the detection of more carcinogenic HR‐HPV type was found, and in all but one cervical intraepithelial neoplasia of grade 3 the presence of at least one HR‐HPV could be detected, with more than 70% of cervical intraepithelial neoplasia of grade 3 patients bearing HPV 16. Multiple infections, comprising between 2 and 6 HPV types, were found in 43% of patients; however, the presence of more than 1 HR‐HPV type was not associated with an increased risk of high grade lesions. In conclusion, this data show that HPV 16, 51, 31, 52, and 18 were the prevalent types found in patients with cervical lesion undergoing conservative treatment, with a high prevalence of HPV 16 in cervical intraepithelial neoplasia of grade 3 patients. No association between multiple infection and severity of the lesion could be found. J. Med. Virol. 81:271–277, 2009. © 2008 Wiley‐Liss, Inc. 相似文献

The prevalence of human papillomavirus (HPV) infections in 2109 females inhabiting five cities of Colombia was determined. Of the 49.2% with an HPV infection, 59.8% were infected with more than one viral type. Species 7 (of the the genus Alphapapillomavirus ) was associated with multiple infections. Analysis of the socio-demographic data revealed a statistically significant protective effect associated with the status of civil union (civil recognition of cohabitation without marriage), and indigenous ethnicity proved to be a risk factor for HPV infection. This is the first study comparing HPV infection among women from geographical regions of Colombia with different socio-cultural structures. 相似文献

This study aimed to determine the prevalence of and risk factors for high‐risk human papillomavirus (HPV) genital infection and precursor lesions of penile cancer among patients infected with human immunodeficiency virus (HIV). In total, 276 men with a mean age of 34.6 years were included. All participants were subjected to peniscopic examination under magnification, collection of genital exfoliated cells for detecting HPV types using Hybrid Capture, and biopsy surgery of clinically observable lesions and aceto‐white areas for histopathological studies. The prevalence of high‐risk HPV types was 43%. Peniscopicy showed clinically visible lesions or aceto‐white areas in 75/276 participants (27%), of which genital warts were the most common (22/75; 29%). HIV‐positive (HIV+) men with CD4+ T‐cell counts <200 cells/mm3 showed a higher prevalence of penile lesions. Multivariate logistic regression was applied to identify independent risk factors for high‐risk HPV types. The results showed that high‐risk HPV was associated with lower education level (OR = 1.89, 95% CI: 1.15–3.13), illicit drug use (OR = 1.80, 95% CI: 1.03–3.14), mulatto ethnicity (OR = 2.51, 95% CI: 1.38–4.54), heterosexual orientation (OR = 2.12, 95% CI: 1.30–3.47) symptomatic AIDS (OR = 2.80, 95% CI: 1.65–4.77), AIDS‐associated opportunistic infections (OR = 2.92, 95% CI: 1.78–4.78), on HAART (OR = 2.91, 95% CI: 1.78–4.77), and CD4+ T‐cell count <200 cells/mm3 (OR = 3.31, 95% CI: 1.84–5.96). Immunocompromised men were more susceptible to developing penile lesions associated with high‐risk HPV types. J. Med. Virol. 85:413–418, 2013. © 2013 Wiley Periodicals, Inc. 相似文献

Background: Cervical cancer remains a major public health problem in northern Argentina, showing the highest mortality rate in the country (approximately 22 cases/100000 women). Objective: The aim of this study was to provide epidemiological data on the prevalence and type distribution of human papillomavirus (HPV) in women with pre-neoplastic lesions before the massive introduction of HPV vaccination in the country. Materials and Methods: Exfoliated cervical cells were collected to screen for HPV using the widely known MY09/11 PCR, followed by the restriction fragment-length polymorphism (RFLP) technique from a total of 714 women with previously diagnosed atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LG-SIL) and high-grade squamous intraepithelial lesion (HG-SIL). Results: Overall HPV prevalence was 48.2% in ASCUS (24 different HPV types detected), 66.5% in LG-SIL (37 HPV types detected) and 82.6% in HG-SIL (16 HPV types detected). HPV-16 was the most prevalent type among all cases. With respect to multiple HPV infections, 9.6% were observed in ASCUS, 14.3% in LG-SIL and 11.4% in HG-SIL. Conclusion: The major strength of our study is the assessment of a large series of women with cytological alterations in this region. The information attained will be useful as a regional baseline for future epidemiological vigilance, in the context of the national HPV vaccination program. 相似文献

Prevalence of 27 human papillomavirus (HPV) genotypes was assessed in 1,331 women in three clinical settings: Family planning clinic (low-risk HIV-, n = 202, 21.3% HPV+), colposcopy clinic (high-risk HIV-, n = 854, 34.3% HPV+), and HIV outpatient clinic (HIV+, n = 275, 48.7% HPV+). Compared to women from both family planning and colposcopy clinics, HIV+ women revealed significantly higher prevalence of infection with oncogenic, non-oncogenic, and multiple HPV types. HPV types 52 and 51 were most prevalent in the low-risk HIV- women, whereas in the high-risk HIV- women, HPV types 16, 52, 58, and 35 were most prevalent. Interestingly, in the HIV+ women, less characterized types 83, 53, and 54 were most prevalent. The distinct profiles of genotype prevalence persisted after stratification by Pap smear status. After adjustment for concurrent infections with other types, HPV type 51 in the low-risk HIV- women, and types 16, 35, 39, 45, 52, and 58 in the high-risk HIV- women were significantly associated with cytologic abnormalities (exact P < 0.05). In HIV+ women across CD4 cell count strata, HPV types 42, 16, and 82 revealed significant decreasing trends with increasing CD4 counts (exact P for trend < 0.05). These data suggest distinct genotypic prevalence profiles in women at diverse risk for cervical cancer. The association of several genotypes with cytologic abnormalities underscores the need for vaccines targeting a wide range of HPV types. 相似文献

A large proportion of human papillomavirus (HPV) infections is sustained by multiple genotypes. The effect of multiple infections on the risk of cervical intraepithelial neoplasia (CIN) and the potential efficacy of vaccine on these infections are controversial. We performed viral typing by SFP10‐LIPA on a consecutive series of 1,323 women undergoing colposcopy, 69% of whom had cervical biopsy, and correlated CIN severity with the type and number of HPVs. Overall prevalence of HPV‐DNA was 68.9%, 97.3% in CIN1, and 98.1% in CIN≥2. HPV positivity correlated with younger age (35.9 vs. 37.3 years, P = 0.026) and history of CIN (P < 0.001). Multiple types were detected in 44.2% of cases, including 63.1% CIN1 and 80.8% CIN≥2. Twenty‐three different types were detected, HPV‐16, 31 and 52 being the most frequent. Infections by HPV‐6, 11, 16, or 18 occurred in 59.4% of CIN1 and 71.3% of CIN≥2. Number of viral types and class of oncogenic risk were linearly correlated with CIN severity (P < 0.0001) by univariate and multivariate analyses controlling for age and history of CIN. The effect of the number of HPV types was maintained after exclusion from the model of infections by HPV‐6, 11, 16, and 18. Frequency, distribution, and clinical correlates of multiple HPV infections highlight the importance of assessing individual types in the management and the prediction of outcome of women with abnormal baseline cytology and point to potential limitations in current vaccine strategies.

The aim of this survey was to assess the prevalence and distribution of oncogenic human papillomavirus (HPV) genotypes in women who underwent screening for cervical cancer in Italy. The correlation of genotypes with the cytological results was also evaluated. Cervical samples were collected from 9,947 self‐referring women for cervical cancer screening. Participants were screened by liquid‐based cytology and high‐risk HPV testing using the Hybrid Capture 2 test. Positive samples were genotyped by PCR. Samples (1,474; 14.8%) were positive for high‐risk HPV. The prevalence was 29.4% in the 15–19 years‐group, decreasing progressively to 6.1% at 50–54 years of age and increasing to 12.2% in those aged over 65 years. HPV 16 was the genotype detected most frequently followed by HPV 31, HPV 18, HPV 56, and HPV 51. HPV 16 or 18 were present in 4% of women with normal cytology and both were detected contemporarily in only 14 women. Twenty‐two percent of atypical squamous cells, 26% of low‐grade and 56% of high‐grade squamous intraepithelial lesions at cytology were positive for HPV 16 and/or 18. The prevalence of HPV infection in Italy is in agreement with that reported worldwide. HPV 16 was the prevalent genotype. The concomitant infection with HPV 16 and HPV 18 (vaccine targets) was found rarely. Apart from HPV 16 and 18, there was a substantial presence of HPV genotypes against which the vaccines available currently have shown cross‐protection efficacy. The findings of this study may contribute to reliable predictions on the potential efficacy of an HPV vaccine in clinical practice. J. Med. Virol. 81:529–535, 2009. © 2009 Wiley‐Liss, Inc. 相似文献

PurposeThe objective of the present study is to verify possible association between infections with mycoplasmas and ureaplasmas and the presence of HPV infections in women diagnosed with abnormal cervical cytology.Material/MethodsThe investigation included 387 non-pregnant women among whom: 62 were diagnosed with ASCUS, 167 with LSIL, 27 with HSIL, 49 with cervical carcinomas, and 82 females with normal cytology.The presence of HPV infection and identification of both ureaplasma and mycoplasma were confirmed by PCR using specific primers.ResultsHPV infections were demonstrated in 156 females (40%), with mycoplasmas and/or ureaplasmas were confirmed in 93 cases (24%).In HPV-positive patients, infections with mycoplasmas/ureaplasmas were more frequent, particularly for ureaplasmas (U. urealyticum p=0.004, U. parvum p=0.027). The percentage of females infected with U. urealyticum significantly increased in women diagnosed with cervical carcinoma as compared to controls.The statistical analysis demonstrated that the risk of HPV infection while already infected with any of the four analyzed species of Mycoplasmataceae increased two-fold. With concomitant of U. urealyticum infection, the risk of HPV infection was 4.7-fold greater than in the absence U. urealyticum infection.ConclusionSince the presence of U.urealyticum associates significantly with the HPV infection, genotyping of the ureaplasma species should be recomended. 相似文献

ObjectiveTo provide data on incidence of early diagnosis of HIV infections and define prevalence and incidence of asymptomatic sexually transmitted infections (STI) in men who have sex with men (MSM).MethodsWe assessed a prospective cohort study of HIV-uninfected MSM at high risk for HIV infection. Participants were selected through a risk-assessment questionnaire, and they were screened for HIV infection (quarterly) and for other STI (yearly): syphilis, and hepatitis A, B and C (serology); Chlamydia trachomatis and Neisseria gonorrhoeae in penis and rectum; and human papillomavirus in anus and mouth (PCR).ResultsBetween November 2009 and October 2012, a total of 258 HIV-uninfected MSM at high risk for HIV infection were included and followed up for a median of 2 years (interquartile range 1.4, 2.5). Nineteen acute HIV infections were diagnosed (incidence, 3.9 per 100 person-years). Prevalence of STI at baseline was follows: syphilis 8.4% (95% confidence interval (CI) 5.4–12.7); hepatitis C virus (HCV) 2.0% (95% CI 0.7–4.8); C. trachomatis in penis 3.2% (95% CI 1.5–6.5) and in rectum 6.5% (95% CI 3.9–10.5); N. gonorrhoeae in penis 2.0% (95% CI 0.8–5.0) and in rectum 6.1% (95% CI 3.6–10.1); human papillomavirus in anal canal 75.7% (95% CI 68.8–81.5) and in mouth 3.8% (95% CI 1.8–7.7).ConclusionsThe implementation of the Check-Ear Project in a MSM community centre allowed for the identification of early HIV infections and asymptomatic STI among MSM. The high incidence of HIV infections and the high prevalence of STI strongly support the recommendation of periodic screenings among sexually active MSM. 相似文献
