Metaplastic cells with nebular cytoplasmic changes in the cervical smear are classified in the Dutch coding system for cervical screening as KOPAC O8 cells. Since these nebulated cells are already documented by Papanicolaou, we refer to these cells as Papanicolaou's nebular cells. We examined the simultaneous presence of these characteristic metaplastic cells and high-grade squamous intraepithelial lesion (HSIL) in a population-based data base from January 1991 and December 1996. The odds ratio (OR) of nebular cells concurring with HSIL increases with age. For the age cohort 30 years, the OR was 7.8 with a 95% confidence interval (CI) of 4.4-13.9. For the age cohort 60 years, the OR was 35.3 with a 95% CI of 7.8-159.2. Aiming to determine the nature of these nebular metaplastic cells, we performed Chlamydia and HPV PCR on 587 and 1,483 smears, respectively. With an OR of 0.9 [0.3-2.4] it is unlikely that Chlamydia plays a role in the appearance of these nebular cells in the smear. This study shows that with an OR of 5.9 [1.7-21.3] HPV is not only related to large koilocytosis but also to a nebular change of small metaplastic cells. This study reports that nebular changes of small metaplastic cells are related to cervical cancer and to HPV infection. 相似文献

We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at ≤25 years, a decline with age and a second peak at ≥55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing. 相似文献

Vaginal intraepithelial neoplasia (VAIN) is often found by chance. We investigated the prevalence of VAIN and related human papillomavirus (HPV) types in comparison with cervical intraepithelial neoplasia (CIN). This study enrolled 648 women who were referred to the outpatient clinic of Kanazawa Medical University Hospital for abnormal cytology from January 2009 to January 2019. HPV genotypes were determined using Genosearch-31 + 4, which can detect 35 different HPV types. Colposcopy was performed at the first visit by an experienced gynecological oncologist. Among 611 subjects with squamous cell lesions, 107 (17.5%) VAIN cases were identified, and 67 (11.0%) women had both VAIN and CIN. Ultimately, 72 VAIN1, 15 VAIN2/3, 203 CIN1, 249 CIN2/3, 32 cervical squamous cell carcinomas (SCC), and one vaginal SCC (Vag-SCC) were identified. The prevalences of VAIN1, VAIN2/3, and Vag-SCC were 35.5%, 6.0%, and 3.1% of equivalent cervical lesions, respectively. The VAIN patients were older than the CIN patients (P = .002). About half of the VAIN cases were diagnosed during the follow-up. Multiple HPV infections were found in 42.9% of the VAIN and CIN patients. HPV52, 16, 51, 53, and 56 were the most common types in VAIN, whereas HPV16, 52, 58, 51, and 31 predominated in CIN. HPV18 was rare in VAIN, HPV58 was more common in CIN than in VAIN, and HPV53 and HPV73 were more common in VAIN. In conclusion, VAIN1 was identified more frequently than we expected. Various HPV types were identified in the vagina, which is likely a reservoir for HPV. 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

In order to investigate the influence of DNA extraction on two PCR-based HPV genotyping tests (Linear Array, Roche and INNO-LiPA Extra, Innogenetics), three different procedures were used to purify DNA from 28 cervico-vaginal samples tested previously by the Hybrid Capture 2: the AmpliLute Liquid Media Extraction kit (Roche), the QIAamp DNA Blood mini kit (QIAGEN), and the NucliSENS EasyMAG automated platform (bioMérieux). All HC2-positive samples were found positive by both assays, independently of the extract used. Type-specific concordance (i.e., identical HPV type-specific profile in all the extracts of the same sample) was observed in 55% and 75% of the cases testing samples by the Linear Array and the INNO-LiPA, respectively. Using the DNA extracted with the two manual methods the results were concordant in 75% of the cases both for the Linear Array and the INNO-LiPA. When comparing the Linear Array results obtained on either of the two manual extracts with those obtained following automated extraction, 65% of the samples showed type-specific concordance in both cases. The INNO-LiPA results were concordant in 80% of the cases comparing the AmpliLute versus the automated extract, while concordant results were observed in 90% of the cases when comparing the QIAGEN versus the automated extract. In conclusion, the Linear Array and INNO-LiPA results are affected by the method of DNA extraction. Consequently, different HPV type-specific profiles may be observed using different extracts of the same sample. The use of consistent protocols for DNA purification is a priority to guarantee intra-assay reproducibility over time. 相似文献

The aim of the study was to evaluate the prevalence and risk factors of HPV in a gynecologic population attending outpatient clinics using two new molecular tests. The Amplicor HPV test and the Linear Array (LA) HPV Genotyping test were used for the detection of HPV DNA in 320 women. Multiple logistic regression was used to identify independent prognostic factors of HPV positivity. The agreement between the two methods in terms of their qualitative results was 89.3% (kappa: 0.63). Based on the LA results, the overall prevalence of HPV DNA was 49.1%, 95% confidence interval (95% CI: 43.5%, 54.7%). The prevalence of high‐risk HPV types was 30.3%. The predominant types were HPV‐6 (24.8%) and HPV‐16 (20.4%). Among women with normal cytology, the prevalence of HPV was much higher in those presenting other findings, such as inflammation, than those without other abnormal findings (49.5% vs. 31.5%). On the basis of multivariate analysis, the risk of HPV infection was higher among women with multiple sexual partners [>3 vs. 1: OR = 3.1, 95% CI: (1.5, 7.2)], Pap smear findings [low/high‐grade lesions vs. negative: OR = 2.8, 95% CI: (1.2, 6.5)], the presence of warts [yes vs. no: OR = 3.0, 95% CI: (1.5, 6.3)] and no history of child birth [no vs. yes: OR = 2.6, 95% CI: (1.0, 6.7)]. Younger age was an additional risk factor for HPV infection with carcinogenic genotypes [OR for 1 year increase = 0.93, 95% CI: (0.89, 0.98)]. J. Med.

Although Romania has one of the highest incidence of cervical cancer in Europe (30 new cases/100 000 women), little is known about the distribution of the human papillomaviruses (HPV) genotypes in this population. We seek to determine the distribution of HPV genotypes in women with normal and abnormal cervical cytology. We analyzed 460 cervical cytology specimens from women who self-referred to the gynecologic clinic. HPV was detected and genotyped using the commercially available INNOLiPA (INNOGENETICS NV) kit based on the reverse hybridization principle. HPV DNA was detected in 279 cases (60.7%) with a median age of 32.9 years. In HGSIL (High Grade Squamous Intraepithelial Lesion) cytology, the presence of HPV DNA was confirmed in 82.7% of cases. The most frequent high-risk genotype was HPV16, found in 32.6% of HPV-positive samples. The next common high-risk genotypes were HPV18, HPV31 and HPV51. Our findings on the distribution and frequency of the HPV genotypes in Romanian population confirmed the utility of the current available HPV vaccines, HPV16 and 18 being detected in 28.7% of cases in the investigated area. 相似文献

Genital human papillomavirus infection (HPV) is common and usually harmless. However, chronic cervical infection with high‐risk HPV types can cause cell changes that may eventually lead to cancer. To determine the frequency of individual HPV types among mixed infections, we examined the type distribution among cervical specimens from more than 1000 Danish women. We also examined the HPV type distribution and the frequency of single and multiple HPV types for specimens from 113 women who underwent conization and were diagnosed with cervical intraepithelial neoplasia grade II or worse (CIN2+). Using microarray technology, we found that 49% of the HPV‐positive patients were infected with multiple HPV types. Among the CIN2+ diagnosed women, this frequency was 41%. The most frequently found high‐risk HPV type was HPV‐16, which was found in 25% of the HPV‐positive cervical specimens. Among the HPV positive CIN2+ diagnosed women, 48% were HPV‐16 positive. Women younger than 30 years of age had a higher frequency of multiple infections (61%) than women older than 30 years (39%). We conclude that cervical infection with multiple HPV types is common among women in all age groups and among women with or without the diagnosis of CIN2+. 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

Despite the high prevalence of cervical cancer and cervical neoplasias in South Africa, few studies have been performed in this region to establish which human papillomavirus (HPV) types are associated with the development of high-grade cervical intraepithelial neoplasia lesions and cervical cancer. To investigate these prevalence rates, punch biopsies were obtained from 56 women with cervical cancer and 141 women with histologically diagnosed cervical intraepithelial neoplasia 2 or 3 lesions. Nested polymerase chain reaction (PCR) using consensus degenerate PCR primers was performed for the detection of HPV DNA and HPV typing was done by restriction fragment length polymorphism. Forty-seven (94%) of the cervical cancer and 114 (88%) of the cervical intraepithelial neoplasia 2/3 biopsies were positive for HPV DNA. The prevalence rates of the HPV types detected in the cervical cancer biopsies were HPV 16 (82%), HPV 18, (10%), HPV 33 (10%), HPV 31 (2%), HPV 58 (2%), HPV 35 (2%), and HPV 59 (2%). The cervical intraepithelial neoplasia lesions contained HPV 16 (56.6%), HPV 33 (14%), HPV 31 (10.9%), HPV X (7%), HPV 52 (3.9), HPV 58 (3.1%), HPV 35 (2.3%), HPV 18 (1.6%), HPV 11 (0.8%). Five of the nine fragments that were not typed by the RFLP, designated HPV-X, were sequenced to give HPV6 (1/5), HPV 26 (2/5), HPV 68 (1/5), and candHPV 87 (1/5). HPV 58 was detected in one cervical cancer biopsy and four biopsies from cervical intraepithelial neoplasia grade 3 lesions and was shown to be a previously described variant [Williamson and Rybicki (1991) J. Med. Virol. 33:165-171]. In addition, a cervical intraepithelial neoplasia grade 2 lesion was shown to harbour HPV type HAN2294 (cand HPV 87). The results of this study indicate that cervical cancer and cervical intraepithelial neoplasia 2/3 are largely associated with HPV 16 infection in this group of South African women and, therefore, an effective HPV 16 based vaccine should prevent the development of cervical cancer in a large proportion of women from this region of South Africa. 相似文献

BackgroundCo-infection of High Risk Human Papillomavirus (HR-HPV) and HIV is thought to favour initiation of intraepithelial squamous cell lesion and subsequent progression to cervical carcinoma.ObjectivesEvaluation of cytological physiognomies in relation to possible age influence and the genotype distribution of human papillomaviruses among HPV/HIV co-infected and HPV monoinfected women in Kisii, Kenya.MethodsThe case-control study enrolled 42 HPV/HIV co-infected and 42 HPV monoinfected women. Cervical swabs were collected in ThinPrep vials for HPV tying and cytological analysis. HPV subtypes were assayed by Xpert® HPV system (GXHPV-CE-10).ResultsMono-infected women aged 30–39 years had the highest proportion of low grade squamous intraepithelial lesion (LSIL) at 14 (16.67%) while the co-infected aged 50–59 years had the highest proportion of high grade squamous intraepithelial lesion (HSIL) at 9 (10.71%). HPV-16 genotype was the most predominant and it increased with age rise. Older coinfected and mono-infected women (>40 years) had HSIL and LSIL as the most predominant cytological grade respectively.ConclusionThe predominance of HPV-16 and HPV-18/45 genotypes in the study setting is a consideration that would benefit targeted prophylactic vaccination programs. HPV testing and cervical cancer screening for young and older women on a regular basis ought to be reinforced. 相似文献

The aim of the present study was to investigate the distribution of HPV genotypes in uterine cervical lesions in Yanbian, northern China. HPV-DNA chip (oligonucleotide microarray) and cervical biopsy were used for 322 women in 1998-2005. All the normal cervical epithelia were negative for HPV. The positive rate of high-risk HPV was 33.9% in cervical intra-epithelial neoplasia (CIN)-1, 51.6% in CIN-2, 57.7% in CIN-3, 66.7% in cervical glandular intra-epithelial neoplasia (CGIN), 91.7% in squamous cell carcinoma (SCC), and 78.6% in adenocarcinoma. HPV-16 was the major type in all CIN and SCC cervical lesions, but in cervical adenocarcinoma HPV-18 was the most common type, and HPV-16 was the second most common type. Several cases of CIN-3, SCC and adenocarcinoma had multiple types of HPV, but there was none in CIN-1/2. In summary, HPV-16 is the type most frequently involved in the development of SCC of the cervix, and this may be helpful for the prediction of the development and progress of CIN-2/3, whereas both HPV-18 and -16 play a prominent role in the development of adenocarcinoma and CGIN of the cervix in Yanbian, northern China. 相似文献
