IntroductionIn Egypt, cervical cancer ranks as the second most frequent cancer after breast cancer, among women between 15 and 44 years of age. High-risk human papillomavirus (HPV) 16 and 18 detection holds the potential to be used as a tool to detect women, at risk for consequent development of cervical cancer because of their predominance and potentially greater oncogenic nature than other high risk HPV subtypes.ObjectiveTo determine the prevalence of high-risk HPV 16/18 DNA in women with abnormal cervical cytology.Subjects and methods45 cases were collected from Egyptian women seeking routine gynecologic care. Ten cytologically normal cervical smear cell samples were included in the study as a control to be tested for the presence of HPV 16/18 DNA and were collected from asymptomatic patients having cystorectocele or coming for loop insertion or removal. The 45 specimens were subjected to real-time polymerase chain reaction, using multiplex HPV 16 and 18 PCR kit.Results45 cervical smears were collected in the present study. Cytopathological examination revealed that 5 (11.1%) were ASCUS, 8 (17.8) were LSIL, 5 (11.1%) were HSIL, 1 (2.2%) was squamous cell carcinoma (SCC), 1 (2.2%) was adenocarcinoma and 25 (55.6%) were benign (inflammatory). 20 patients with abnormal cervical cytology and 10 controls were included in the present study. In patients with abnormal cervical cytology, 5 (25%) were ASCUS, 8 (40%) were LSIL, 5 (25%) were HSIL, and 1 (5%) was SCC and 1 (5%) was adenocarcinoma. Statistical analysis revealed a significant difference between patient and control groups as regards regularity of menstruation where irregular menstruation and higher prevalence of menopausal women, abnormal vaginal bleeding, menorrhagia, vaginal infection, and abnormal cervical appearance were encountered in patients. A statistically significant higher prevalence of married women was found in the control group. There was no significant difference in the distribution of patients and control as regards HPV 16 or HPV 18 in which 20% of patients were HPV 16 positive and 10% of patients were HPV 18 positive compared with none in the control group. 6 were positive either for HPV 16 or 18, while 39 were negative. The HPV 16/18 positive patients had significantly higher age and marital duration when compared with HPV 16/18 negative group. Significantly, most of the HPV 16/18 positive patients were menopause. A significantly higher prevalence of women with cervicitis, contraceptive users and married women was in the HPV 16/18 negative group.ConclusionThe study generates epidemiological data of prevalence of HPV 16/18 in cytologically abnormal cervical smears in women seeking routine gynecologic care at the outpatient clinics of the Obstetrics and Gynecology Department at El Shatby University. High-risk HPV DNA testing by PCR of cervical samples diagnosed according to the Bethesda 2001 guidelines may benefit the management of patients with abnormal cervical smears, especially among women aged 46 years and older, in menopausal women and in women complaining of PMB. Therefore, HPV DNA testing should be made use of as an adjunct to cervical smears. 相似文献

Aim of Study: To investigate the prevalence of high-risk human papillomavirus (HPV) and its associated cytological abnormalities among women attending cervical screening clinics in southern Malaysia and Singapore.
Method: Laboratory results of Hybrid Capture-II (Digene) HPV DNA and liquid-based cytology tests of consecutive women who had screening performed between January 2004 and December 2006 were studied retrospectively.
Results: Of 2364 women studied, the overall prevalence of high-risk HPV DNA detection rate was 25.6%. The prevalence peaked at 49.1% for women between 20 and 24 years old and declined to 23% among women between the age of 30 and 49 years. A small second peak of prevalence rate of 30% was observed among women above the age of 50 years old. 76.1% of the high-risk HPV infection regressed within the study period. An incidence infection rate of 16% was noted among a small group of women who had a second HPV DNA test. A total of 1153 women had both the HPV DNA and the cytology tests. Cytological abnormality (ASCUS or more) was detected in 8.9% in HPV DNA-positive group and in 3.1% in HPV DNA-negative group ( P < 0.001). The risk ratio for HSIL was 9.8 for HPV-positive women compared to HPV-negative women. The prevalence of cytological abnormalities increased with increasing age of the women.
Conclusion: The epidemiology and clinical impact of high-risk HPV infection for women in Southern Malaysia and Singapore were indistinguishable from experience elsewhere. The apparent moderately high incidence of cervical cancer was explainable by suboptimal screening program. 相似文献

OBJECTIVE: To assess the prevalence and potential risk factors associated with human papillomavirus (HPV) cervical infection among women residing in a region of northeastern Argentina with a high incidence of cervical cancer. METHODS: A case-control study of 330 women participating in a cervical cytological screening program conducted in Posadas city, Misiones, Argentina, from February 1997 to November 1998 was carried out. Standardized questionnaires were administered, and clinical examination including colposcopy was performed. Fresh endocervical specimens for HPV DNA detection by generic polymerase chain reaction were collected and the products typed by dot-blot hybridization. RESULTS: Human papillomavirus DNA was found in 61% of samples analyzed (185/301). Samples with normal cytology had a 43% infection rate (85/199), while those classified as low-grade squamous intraepithelial lesion, high-grade squamous intraepithelial lesion, and invasive cervical carcinoma had an infection rate of 96% (53/55), 100% (29/29), and 100% (18/18), respectively. Human papillomavirus typing showed a 64% (118/185) prevalence of type 16 among all the infected population analyzed; type 16 was detected among 49% (42/85) of infected samples with normal cytology and in an average of 74% (74/100) with abnormal cytology. Sexual behavior, residence in southern Paraguay, and history of a previous sexually transmitted diseases were the main risk factors associated with high-grade cervical lesions. CONCLUSIONS: An elevated prevalence of HPV infection was detected in this population, which also has a high incidence of cervical cancer. The broad distribution of high-risk HPV type 16 in women with normal cytology and colposcopy suggests that viral infection is an important determinant of regional cancer incidence. 相似文献

PURPOSE OF INVESTIGATION: To determine the prevalence of human papillomavirus (HPV) using polymerase chain reaction (PCR) in women with abnormal cytology results. METHODS: A prospective study of 215 women with abnormal cytology results referred consecutively to the cervical pathology clinic was carried out. A second cervical cytology using the Bethesda System was performed on all the patients to confirm the initial diagnosis, as well as to test for the presence of HPV by PCR and a colposcopy and punch biopsy in cases presenting with an abnormal pattern on colposcopy. The sensivitiy, specificity, and positive and negative predictive value (PPV and NPV) were calculated using 2 x 2 tables. RESULTS: The women aged 35 years or younger presented a higher percentage of HPV infection (85.6%) than the women over 35 years of age (54%). The highest percentage of women with a positive result for HPV was found in those with a cytological high-grade squamous intraepithelial lesion (HSIL) (85.5%), as compared with 47.4% of the women with a cytological low-grade squamous intraepithelial lesion (LSIL). HPV infection has a high negative predictive value (93.2% of cases) and a high sensitivity (93.5%) for the detection of HSIL by biopsy, although the specificity and positive predictive value were low, 51.5% and 52.1%, respectively. CONCLUSION: Patients with cytological HSIL have a high prevalence of HPV infection. 相似文献

OBJECTIVES: To assess the performance of a novel PCR-based assay (Roche AMPLICOR HPV test) in detection of cervical pathology as a part of management for abnormal PAP smear (MAPS) and in women participating in cervical cancer screening. STUDY DESIGN: Altogether, 504 women comprising 270 patients referred for colposcopy due to an abnormal Pap smear and another 234 women participating in cervical cancer screening (tested for comparison) were analyzed for oncogenic (HR) Human papillomavirus (HPV) types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68 using the Roche AMPLICOR HPV test in cervical samples collected in PreservCyt liquid media. Colposcopic biopsy and/or LEEP cone biopsy was used as the gold standard in the triage group, while liquid-based cytology (LBC) was the reference test in the screening group. RESULTS: The prevalence of HPV was significantly higher in the MAPS group (65.9%) than in the screening group (31.2%) (P = 0.0001). There was a poor concordance between the referral PAP and the current LBC, being only moderate in the screening series, ICC (weighted kappa) = 0.291 (95%CI 0.070-0.459) (P = 0.007), and almost poor in the MAPS Series, with ICC = 0.217 (95%CI 0.04-0.384) (P = 0.023). AMPLICOR HPV positivity increased linearly with the increasing grade of cervical lesions. In detecting high-grade (CIN2-3), colposcopy was the most sensitive test (96.5%), very similar to AMPLICOR (95.2%) (P = 0.731), while LBC with HSIL cutoff was by far the most specific test (99.5%) and showed the highest PPV (96.1%). NPV of colposcopy (97.2%) and AMPLICOR (96.7%) were similar (P = 0.839). Together with abnormal colposcopy and HSIL cytology, the AMPLICOR HPV test is a powerful independent predictor of high-grade CIN2-3, and as such suitable to replace cervical cytology in management of women with abnormal PAP test (MAPS). CONCLUSIONS: The Roche AMPLICOR HPV test is comparable to other HPV tests (HCII, PCR) in detecting CIN in MAPS. However, more data are clearly needed on the performance of AMPLICOR test in management of abnormal PAP and particularly as a screening tool. 相似文献

OBJECTIVE: To evaluate the association between high-risk human papillomavirus (HPV) DNA detection and histological diagnosis in women referred for atypical glandular cells (AGC) or adenocarcinoma in situ (AIS) at Pap smear. METHODS: In this cross-sectional study, 146 women referred for AGC (124), AGC with high-grade squamous intraepithelial lesion (HSIL) (15), or AIS (7) were tested for HPV DNA using Hybrid Capture II (HC II). All women underwent colposcopic examination, and cervical biopsy was performed for 95 patients. Fifty-one women referred due to AGC with normal colposcopy and normal second Pap smear were scheduled for control visits every 4 months. RESULTS: The overall prevalence of HPV DNA was 38%. HPV DNA was detected in 93% of the women with HSIL associated with AGC and in 71% of women with AIS Pap smear, being significantly higher when compared with the prevalence (29%) in women with AGC alone. Forty-five women (30.8%) had clinically significant histological lesions (CIN 2 or worse). High-risk HPV DNA was detected in only 16% of the women without significant abnormalities in biopsy, in contrast to 96% of those who had CIN 2 or CIN 3 and 75% of women with AIS. Eighty-five percent of women with invasive cervical carcinoma (squamous or adenocarcinoma) tested positive for HPV DNA. HPV DNA detection was significantly associated with histological diagnosis of CIN 2 or worse, with an odds ratio (OR) = 51.8 (95% CI 14.3-199.9). CONCLUSION: HPV DNA detection was strongly associated with the severity of cervical lesion (CIN 2 or worse) in women referred for AGC or AIS in their Pap smear. These data implicate the use of HPV testing in triage of women with AGC Pap smears. 相似文献

Objective
The molecular and epidemiologic effect of human papillomavirus (HPV) coinfections in the risk of developing cervical cancer is yet unclear. The aim of this study was to determine the frequency HPV coinfections at different stages of cervical lesions in the development of cervical cancer and the impact of HPV specific type interactions on high-grade squamous intraepithelial lesions (HSIL) and invasive cervical cancer (ICC) risk.Methods
HPV testing was performed in 931 cervical samples diagnosed as: negative for intraepithelial lesion or malignancy (NILM); low-grade squamous intraepithelial lesion (LSIL); HSIL; and ICC. For HPV detection and typing two sets of primers from the L1 region were used in the polymerase chain reaction method (PCR) (MY09/MY11/HMB01 and L1C1/L1C2.1/L1C2.2) and HPV type was determined by PCR product sequence. To look for multiple HPV infections, the E6 nested multiplex PCR method was performed in all DNA samples. Odds ratios were calculated as indexes of the strength of the association between the sample category (LSIL/NILM or ICC/HSIL) and the presence of a given viral combination.Results
In HPV positive samples, coinfections are as common in ICC/HSIL as in LSIL/NILM (47.12% and 40.17%, respectively). There is an increased risk to ICC/HSIL when multiple high-risk HPV types are present. The coinfection of HPV68 with HPV16 increases the risk of ICC/HSIL (OR = 14.54, P = 0.012, after multivariate adjustment), related to the presence of HPV16 or HPV68 alone.Conclusions
These results sustain that specific HPV coinfections confer an increased risk to develop ICC/HSIL. 相似文献9.
Human papillomavirus infection and cervical disease in human immunodeficiency virus-1-infected women
Denny L Boa R Williamson AL Allan B Hardie D Stan R Myer L 《Obstetrics and gynecology》2008,111(6):1380-1387
OBJECTIVE: To report on the natural history of high-risk human papillomavirus (HPV) infection and cervical disease in human immunodeficiency virus (HIV)-1-infected women living in Cape Town, South Africa. METHODS: This was a prospective study of 400 untreated, HIV-1-infected women who underwent high-risk HPV DNA testing, cytology, colposcopy, histology, and CD4 count testing every 6 months for 36 months. Human immunodeficiency virus viral loads and HPV type distribution were determined at entry and after 18 months. RESULTS: Sixty-eight percent of the women were high-risk HPV DNA positive at entry, 35% had a cytologic diagnosis of low-grade squamous intraepithelial lesion (LSIL), and 13% had high-grade squamous intraepithelial lesion (HSIL). There were no cancers. Abnormal cytology and high-risk HPV positivity were strongly correlated with low CD4 counts and high HIV viral loads. The most prevalent types of HPV were HPV-16, -52, -53, -35, and -18. Incident high-risk HPV infection occurred in 22%, and of those infected with high-risk HPV, 94% of infections persisted over an 18-month period, and 6% cleared their infections. Cytologic progression to SIL from normal/atypical squamous cells of undetermined significance cytology occurred in 17% of cases, but only 4% of cases of LSIL progressed to HSIL. CONCLUSION: There is a high level of high-risk HPV infection in HIV-1 infected women, but progression to HSIL over 36 months occurred in the minority of cases. We recommend an initial colposcopy for an abnormal test, and if no high-grade lesion is identified, triennial screening would be appropriate. Human papillomavirus type 16 was the commonest, and HPV-18 was the fifth commonest, suggesting that vaccination against these two types would have a significant effect. LEVEL OF EVIDENCE: II. 相似文献

Human papillomavirus (HPV) DNA detection in cervical specimens was correlated with cytologic and histologic diagnoses for 151 women who were referred to the Johns Hopkins Hospital colposcopy clinic for evaluation of an abnormal Pap smear. HPVs were identified as “high-risk” or “low-risk” by Hybrid Capture. The final disease status was categorized as high-grade squamous intraepithelial lesion (HSIL) by histology (n= 26), low-grade squamous intraepithelial lesion (LSIL) by histology (n= 43), equivocal [histology negative, cytology atypical squamous cells of undetermined significance (ASCUS) or higher,n= 42], and negative (both histology and cytology negative,n= 40). Thirty-five percent of disease-negative women and 84% of the women with biopsy-proven or equivocal disease were HPV-positive. Ninety-two percent of the HPV-positive women harbored high-risk HPVs, either high-risk HPVs alone (77%) or high-risk HPVs along with low-risk HPVs (15%). High-risk HPVs predominated in disease-negative as well as disease-positive women. Collection of specimens with a cytobrush was more efficient for HPV DNA detection than collection by cervicovaginal lavage. Large amounts of HPV DNA correlated with presence of HSIL or LSIL. For detection of HSIL, considering only brush samples, the sensitivities of abnormal cytology (ASCUS or higher), of high-risk HPVs, and of the two combined were, respectively, 87, 93, and 100%; the corresponding specificities were 30, 30, and 20%. HPV DNA detection may be most beneficial in populations with low HPV prevalence. 相似文献

This study was designed to investigate the genotypes of human papillomavirus (HPV) in Korean women who had abnormal cervical cytology and to evaluate the clinical accuracy of HPV DNA chip analysis for the diagnosis of cervical neoplasia. Liquid-based cytology preparations, HPV DNA chip analysis, and cervical biopsy were performed in 2358 women. High-risk HPV was identified in 23.5% of 1650 histologically confirmed normal samples (including cervicitis and squamous metaplasia) and in 81.8% of 708 samples with cervical intraepithelial neoplasia (CIN) and carcinoma (P<0.01). The major prevalent high-risk HPV genotypes in 381 samples of CIN II/III were HPV-16, -58, -33, and -31, in order of prevalence rate (average overall, 78.0%), and HPV-16, -18, -58, and -33 (average overall, 81.2%) in 133 samples of squamous cell carcinoma (SCC). The infection rate of HPV-16 was significantly higher than that of other high-risk HPV genotypes in all normal, CIN, and SCC cases (P < 0.01) and increased with more advanced squamous cervical lesions (P<0.01). The detection accuracy of high-risk HPV using HPV DNA chip analysis for CIN II or worse was as follows: sensitivity 84% (81-87%), specificity 72% (70-74%), positive predictive value 47% (44-50%), and negative predictive value 94% (92-95%). These results suggest that HPV DNA chip analysis may be a reliable diagnostic tool for the detection of cervical neoplasia and that there are geographic differences in the distribution of high-risk HPV genotypes. 相似文献

Human papillomavirus (HPV) DNA in cervical scrape samples of married women from Manipur (n= 692) and Sikkim (n= 415) in northeast India was determined and compared with that of women from West Bengal (n= 1112) in eastern India by polymerase chain reaction. HPV prevalence was lower in Manipur (7.4%) than in Sikkim (12.5%), which was closely followed by West Bengal (12.9%). HPV18 was predominant in Manipur (2.03%) and strikingly lower (0.2%) in Sikkim and West Bengal (0.9%), while the reverse was true for HPV16. The proportion of HPV16/18 infections in Manipur (3.3%, 22/672) and Sikkim (3.89%, 14/359) were comparable and significantly lower compared to that in West Bengal (7.8%, 79/1007) among women having normal cervical cytology. Such prevalence was similar among all age groups in Manipur: increased with age for women in Sikkim and dropped with age for those in West Bengal similar to that reported previously. At age < or =30 years, HPV16/18 prevalence in Manipur (3.3%) and Sikkim (2.5%) was comparable but was significantly lower (P < 0.05) in contrast to that in West Bengal (8.8%). Among abnormal cytologic lesions, HPV16/18 infections were significantly higher than in normals (P= 0.000) both in Sikkim (14.3%) and West Bengal (20.9%) and absent in Manipur. Such prevalence was noted among women in Sikkim aged >30 years and equally among those in West Bengal aged < or =30 or >30 years. Thus, women from northeast India, particularly from Manipur, appear less susceptible to HPV16/18 infection and related cervical lesions compared to those from West Bengal, where such proneness was prominently evident at age < or =30 years. 相似文献

OBJECTIVE: To investigate the prevalence and type distribution of human papillomavirus (HPV) in women with normal cervical cytology and with cervical intraepithelial neoplasia I to III(CIN) or carcinoma of the cervix in Okinawa, Japan. METHODS: We investigated HPV DNA in 4,078 subjects with cytologically normal cervices, 279 subjects with CIN, and 383 subjects with cervical cancer in Okinawa Prefecture in Japan. The presence of HPV DNA was also compared among generations. HPV DNA was both detected and typed using polymerase chain reaction (PCR). RESULTS: The HPV positivity rate was 10.6% in the subjects who were normal on cervical cytodiagnosis. In each generation, the positivity rate was 20.4% in women aged 20-29 years and approximately 10% in the groups aged 30-89 years, with significant differences among generations. The HPV positivity rates in CIN and cervical cancer groups were 76.0% and 86.2%, respectively, with no significant difference between the groups. The positivity rate of HPV 16 decreased with age in both CIN and cervical cancer groups. CONCLUSION: Among non-cancer subjects, HPV infection rates were almost 20% in women aged 20-29 years and 10% in women aged 30-89 years. HPV16-positive CIN or carcinoma were more prevalent in the younger women, suggesting that HPV16-infected epithelial cells rapidly progress to cervical cancer. 相似文献

Objective
The aim of this study is to determine the rates of single and multiple type human papillomavirus (HPV) infection in women in the United States ages 31–65 with known cervical cytology results.Methods
Type-specific HPV analyses were conducted using the first samples of women who had HPV typing performed by Access Genetics as part of cervical cancer screening between July 2007 and May 2011. Women 31–65 years at testing with associated abnormal cytology results were included. The odds of abnormal cytology (compared to normal results) for multiple vs. single HPV infections were calculated for each cytology sub-type and odds ratios (OR) and 95% confidence intervals (CI) are reported.Results
The analysis included 8182 women. The majority (67.7%) had ASCUS cervical cytology. A total of 329 (4.0%) were positive for 2 or more HPV types. For all cervical cytology subtypes considered (ASCUS, ASCUS-H, LSIL or HSIL), women with multiple type infections were more likely to have abnormal cytology (compared to normal cytology) with the highest OR associated with HSIL (OR 1.81 (1.26–2.60)). When analyzing HPV type 16 alone, women with multiple type infections were more likely to have abnormal cytology, with the highest OR associated with HSIL cytology (OR 2.98 (1.57–5.64)). Few women had HPV type 18 infections and no results reached statistical significance. Results based on phylogenic family organization focusing on the alpha 9 phylogenic family showed similar results as HPV type 16.Conclusions
Women ages 31–65 with multiple type HPV infections were more likely to have abnormal cytology than those with single HPV type infections. 相似文献16.

OBJECTIVE: To study the prevalence of high-risk human papillomavirus (HR-HPV) types 16 and 18 in healthy women with negative Pap smears in identifying women with underlying cervical squamous intra-epithelial (SIL) lesions. METHODS: A total of 3300 women who were attending the Gynecology OPD of Lok Nayak Hospital, one of the major government tertiary hospitals in New Delhi, were screened during a 1-year study period, and 2079 (63%) of them were found to have cytologically negative Pap smear with inflammation and the rest (37%) also had negative Pap report but without inflammation. Hundred and sixty of these sexually active women aged between 20 and 60 years were randomly selected, and were investigated by colposcopy and a guided biopsy was done wherever required. HPV types 16 and 18 DNA was detected in scraped cervical cells from all women using type-specific primers in polymerase chain reaction (PCR). RESULTS: The high-risk HPV (type 16 and 18) prevalence by PCR was found to be 10% (16/160). Histopathological findings were obtained in 123 women, out of which 15 had LSIL and four had HSIL. High-risk HPV types 16/18 could be detected in nine out of these 19 (47.3%) squamous intra-epithelial lesions (p < 0.00008) which includes two out of the four women (50%) having HSIL, while only seven out of 104 (6.7%) of the subjects with normal (negative) Pap reports (p = 0.03) had infection of high-risk HPV. CONCLUSION: The results indicate that about 10% of women who show a negative Pap smear, but have inflammation are positive for high-risk HPV types 16/18 and about 15% harbor squamous intra-epithelial lesions. It is suggested that high-risk HPV detection can be utilized as an adjunct to routine cytology screening programs to identify 'high risk' women who have concurrently negative Pap smears but may harbor oncogenic HPV infection and/or more likely to develop CIN lesions. 相似文献

Objective
To describe the distribution of specific types of low-risk (LR) human papillomavirus (HPV) among a general population of northern Chinese women.Methods
Between 2007 and 2012, 118 096 women were tested with the HPV Geno-Array Test Kit (HybriBio) at China Medical University’s Shengjing Affiliated Hospital, Shenyang, China. Among these women, 80 418 underwent cervical cytology and colposcopic examination, and 30 961 of these had a cervical biopsy. The prevalence of HPV infection among the women was analyzed according to age, and cytologic and histologic findings.Results
CP8304 was the most common type of LR-HPV overall, and was most prevalent in the youngest age group. The overall prevalence of LR-HPV (averaged across all types) was 1.7% in women with normal cytology, 8.8% in those with atypical squamous cells of undetermined significance (ASCUS), 8.0% in those with low-grade squamous intraepithelial lesions (LSIL), and 5.8% in those with high-grade squamous intraepithelial lesions (HSIL). LR-HPV alone, without any high-risk (HR)-HPV, was most common among women with ASCUS and cervical intraepithelial neoplasia (CIN) not otherwise specified (CINNOS) together. Co-infections of LR-HPV and HR-HPV were most common among women with LSIL and CIN1.Conclusion
These data will facilitate modeling of the cost-effectiveness of a prophylactic LR-HPV vaccination in China. 相似文献18.

Human papillomavirus (HPV) has been implicated in the development of cervical cancer. Newly developed molecular techniques have facilitated HPV identification and typing of cervical lesions. Several studies have suggested a strong correlation between HPV16 and intraepithelial cervical neoplasia. However, there is no agreement on this point since HPV16 is detected also in normal cervical tissue. We have amplified the L1 region of HPV16 DNA using the polymerase chain reaction (PCR) technique and analyzed the HPV16 prevalence in cytological scrapes of 201 Italian sexually active patients. One hundred twenty-four of these women had normal cytologic and colposcopic examination, while seventy-seven women had normal or abnormal cytology and a cervical lesion detectable by colposcopy. Within this latter group, 25 of 77 women (32.4%) were positive for HPV16 DNA, compared to 11 of 124 samples (8.87%) from women with normal cytology and colposcopy. The present results confirm the high efficiency of the PCR technique in detecting HPV16 DNA from cervical scrapes and suggest that this analysis should become a method of choice in clinical studies. 相似文献

Papanicolaou tests, PCR for HPV, C. trachomatis, HSV-1/2 and N. gonorrhoea, and Hybrid Capture II were performed for high- and low-risk HPV groups during screening for cervical cancer in 49 women of the Parakana tribe. Cytological diagnoses of HPV were suggested in three samples: PCR showed 12 (22.4%) cases of DNA positive HPV, 16 (1), 18 (2), 58 (3), 39 (1), 61 (1), 33 (1), 35 (1), unknown (2), and HCII analyzed 48 samples: 19 positive (39.58%) for the high-risk group and four (18.33%) for the low-risk group. The prevalence of HPV was 42.85% (p = 0.001) by molecular biology methods. The largest viral load was 1588.11 pg/ml for HPV 39 in a 16-year-old. PCR was positive for C. trachomatis and negative for HSV-1/2 and N. gonorrhoea. Parakana women present a high risk for the development of cervical cancer. 相似文献

BACKGROUND: Human papillomavirus (HPV) infections are associated with cervical cancer. There were only a few reports and detailed data about epidemiological research of HPV infection in general population of China. AIMS: To determine the prevalence of genital HPV infection in Chinese women of Guangdong province. METHODS: A total of 1705 women were screened by gene chip. All HPV-positive women were further examined by ThinPrep liquid-based cytology test (TCT), and the cervical biopsies of those women with positive HPV-DNA and abnormal TCT were collected for pathological diagnosis. RESULTS: The overall HPV prevalence was 9.03% (154 of 1705), and 72.3% (126 of 154) of total positive samples were high-risk types, with higher prevalence of types 52, 58, 16, 18 and CP8304. For women aged 51 years or older, the overall high-risk HPV prevalence was 12.2% (24 of 179), which was obviously higher than those of other age groups (P < 0.05). CONCLUSIONS: Our results showed that the HPV prevalence in Guangdong is very similar to the world level. Unlike most previous studies, our findings suggest that HPV prevalence increased with age, and that the predominant genotypes in this area were HPV 52 and 58. 相似文献
