Int J Gynaecol Obstet 2023; 161:79-85. [PMID: 36184575 DOI: 10.1002/ijgo.14486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 02/07/2022] [Accepted: 09/26/2022] [Indexed: 11/11/2022]
Abstract
OBJECTIVES To evaluate clinical performance and diagnostic accuracy of urinary HPV for non-invasive screening of high-grade precancerous and cancerous cervical lesions in a visual inspection under acetic acid (VIA) -positive cohort. METHOD The study included 180 women aged 35-65 years, who were VIA positive in a colposcopy clinic. All participants had the initial stream of a random urine sample tested for the presence of high-risk HPV (hrHPV) types 16 and 18 and acetowhite lesions were biopsied per protocol. Concordance analysis was conducted to assess agreement between detection of hrHPV in urine and the presence of premalignant and malignant lesions in cervix on histopathology. Measures of diagnostic accuracy were estimated to evaluate the performance of urinary HPV against histopathology (reference standard). RESULTS Substantial agreement between urinary HPV detection and histopathology was found (Cohen's κ is 0.696, P ≤ 0.001), with an agreement in 88.9% of the cases and disagreement in 11.1%. The diagnostic performance of urinary HPV in predicting the presence of a high-grade precancerous or cancerous lesion was as follows: sensitivity 67%, specificity 97%, positive predictive value 89%, and negative predictive value 88.8%. CONCLUSION HPV DNA detection from urine has good concordance with the histopathology for detection of precancerous and cancerous lesions of the cervix. Further studies on optimization of urine sampling and processing techniques are warranted.

Abstract
Background Cervical cancer (CC) is the fourth leading cause of death from neoplasms in women and is caused by the human papilloma virus (HPV). Several methods have been developed for the screening of cervical lesions and HPV; however, some socio-cultural factors prevent women from undergoing gynecological inspection, which results in a higher risk of mortality from cervical cancer in certain population groups as indigenous communities. This study aimed to compare the concordance in HPV detection from urine and cervical samples, to propose an alternative to cervical scraping, which is commonly used in the cervical cancer screening. Methodology The DNA from cervical scrapings and urine samples was extracted using the proteinase K method followed by precipitation with alcohol, phenol andchloroform; a modification of the proteinase K method was developed in the management of urine sediment. Viral genotyping was performed using INNOLipa. Results The study population consisted of 108 patients from an indigenous population at southern Mexico, 32 without squamous intraepithelial lesions (NSIL) and 76 with low squamous intraepithelial lesions (LSIL). The majority of NSIL cervical scrapes were negative for HPV (90.63%), whereas more than half of LSIL cases were high-risk HPV positive (51.32%), followed by multiple infection by HR-HPV (17.11%), and multiple infection by LR- and HR-HPV (9.21%). No statistically significant relationship between the cytological diagnosis and the HPV genotypes detected in the urine samples was observed. A concordance of 68.27% for HPV positivity from urine and cervical samples was observed. Similarly, a concordance of 64.52% was observed in the grouping of HPVs by oncogenic risk. HR-HPV was detected in 71% of the urine samples from women with LSIL diagnosis, which suggests that HR-HPV detected in a urine sample could indicate the presence or risk of developing SIL. Conclusion HR-HPV detection in urine samples could be an initial approach for women at risk of developing LSIL and who, for cultural reasons, refuse to undergo a gynecological inspection.

Abstract
Urine samples provide a potential alternative to physician-taken or self-collected cervical samples for cervical screening. Screening by primary hrHPV testing requires additional risk assessment (so-called triage) of hrHPV-positive women. Molecular markers, such as DNA methylation, have proven most valuable for triage when applied to cervical specimens. This study was set out to compare hrHPV and DNA methylation results in paired urine and cervical scrapes, and to evaluate the feasibility of DNA methylation analysis in urine to detect cervical cancer. Urine samples (n = 41; native and sediment) and paired cervical scrapes (n = 38) from cervical cancer patients, and urine from 44 female controls, were tested for hrHPV and 6 methylation markers. Results on native urine and sediment were highly comparable. A strong agreement was found between hrHPV testing on urine and scrapes (kappa = 0.79). Also, methylation levels in urine were moderately to strongly correlated to those detected in scrapes (r = 0.508-0.717). All markers were significantly increased in urine from cervical cancer patients compared to controls and showed a good discriminatory power for cervical cancer (AUC = 0.744-0.887). Our results show a good agreement of urine-based molecular analysis with reference cervical samples, and suggest that urine-based DNA methylation testing may provide a promising strategy for cervical cancer detection.

Abstract
Genital human papillomavirus (HPV) is the world’s most commonly diagnosed sexually transmitted infection, and high-risk HPV types are strongly linked to cervical dysplasia and carcinoma. Puerto Ricans are among the US citizens with higher HPV prevalence and lower screening rates and access to treatment. This bleak statistic was as a motivation to detect biomarkers for early diagnosis of HPV in this population. We collected both urine and cervical swabs from 43 patients attending San Juan Clinics. Cervical swabs were used for genomic DNA extractions and HPV genotyping with the HPV SPF10-LiPA25 kit, and gas chromatography-mass spectrometry (GC-MS) was employed on the urine-derived products for metabolomics analyses. We aimed at discriminating between patients with different HPV categories: HPV negative (HPV-), HPV positive with simultaneous low and high-risk infections (HPV+B) and HPV positive exclusively high-risk (HPV+H). We found that the metabolome of HPV+B is closer to HPV- than to HPV+H supporting evidence that suggests HPV co-infections may be antagonistic due to viral interference leading to a lower propensity for cervical cancer development. In contrast, metabolites of patients with HPV+H were significantly different from those that were HPV-. We identified three urinary metabolites 5-Oxoprolinate, Erythronic acid and N-Acetylaspartic acid that discriminate HPV+H cases from negative controls. These metabolites are known to be involved in a variety of biochemical processes related to energy and metabolism and may likely be biomarkers for HPV high-risk cervical infection. However, further validation should follow using a larger patient cohort and diverse populations to confirm our finding.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infectious agent and is the main cause of cervical cancer (CC). In Chile, CC is the second leading cause of death by cancer in women aged 20-44 years, four times higher than in developed countries. Currently, the detection of HPV infection using a cervical brush is recommended; however, this is an invasive procedure that many women try to avoid. The aim of this study was to evaluate the clinical performance of a self-collected, urine-based HPV detection method using conventional PCR followed by a reverse line blot. A PCR-based HPV genotyping was performed on 190 paired cervical and urine samples from gynecological exams at public health centers in the Araucania Region, Chile. HPV DNA detection and genotyping were performed by PCR and reverse line blot assay. Carcinogenic HPV types were present in 64.7% and 65.8% of the cervical and urine samples; the infection rates of HPV16 were 34.7% and 33.2%, respectively. The overall percent agreement between carcinogenic HPV detection in cervical and urine samples was 73.7%, with a moderate concordance rate of carcinogenic HPV detection (kappa = 0.42). Clinical sensitivities for cervical and urine-based sampling methods to diagnose cervical intraepithelial neoplasia 2/3 (CIN2/3) by histology were 93.4% and 90.2%, respectively. These results suggest that both cervical brush and urine-based sampling show a good clinical performance in the detection of HPV infection. The urine-based sampling method represents a valuable alternative with a great impact on public health, allowing increased cervical cancer screening coverage among women who do not undergo pelvic examinations.

Abstract
HPV have been identified as high-risk and low-risk, depending on their association with the development of cancer. HPV infections can be facilitated by co-infection with HIV. Here, we investigated HPV prevalence and genotypes and the risk factors affecting HPV/HIV co-infection. Forty HIV-positive patients had 80 cervical swab samples collected in 2 consecutive years. Polymerase chain reaction and DNA direct sequencing were used to perform HPV genotyping. Statistical analyses were performed regarding risk factors for HPV/HIV co-infection and the occurrence of cervical lesions. HPV DNA was detected in 59 samples (73.75%), and high-risk HPVs were predominant (59.3%). The most prevalent type was HPV56 (17%), followed by HPV16 (15.3%). Patient age did not affect the risk of cervical cancer (P = .84) or HPV prevalence in different years (P = .25/P = .63). CD4 count also did not affect the risk for cervical lesions in the tested samples (P = .15/P = .28). Although the HIV viral load was not correlated with an increase in cervical lesion detection in the first group of analyzed samples (P = .12), it did affect cervical cancer risk in the group of samples analyzed in the following year (P = .045). HIV-infected patients presented a high prevalence of HPV co-infection, and HPV16 and HPV56 were the most prevalent genotypes. Considering this, it is possible that immunodeficiency can contribute to increased susceptibility to HPV56 infection in HIV-infected patients. The association between HIV viral load and the lesions also confirmed the importance of monitoring HIV/HPV co-infected patients with high HIV viral loads.

Abstract
OBJECTIVE To assess the sensitivity of a urine test for high-risk HPV DNA genotypes in the detection of high-grade squamous intra-epithelial lesion (HSIL) and its correlation with pathologic precancerous lesions. METHODS The present prospective cross-sectional study included women referred to Kasr AlAiny Medical School, Cairo, Egypt, for cervical smear anomalies, a history of cervical smear anomalies, or for suspicious cervix between May 1, 2015, and April 30, 2017. Paired urine tests and cervical smears were performed. HPV DNA was detected in urine using polymerase chain reaction and cervical smears were performed with a cervical spatula and a cytobrush. Agreement between urine test results and pathology was examined. RESULTS In total, 1375 women were included. Urine test for high-risk HPV DNA demonstrated 97.8% (95% confidence interval [CI] 92.1%-99.7%) sensitivity and 100% (95% CI 99.7%-100.0%) specificity for HSIL. Overall, 87 women had a positive urine test for high-risk HPV; of these, 82 (94.3%, 95% CI 87.1%-98.1%) had pathologic findings of cervical intra-epithelial neoplasia 2 or 3 (CIN2/3). Similarly, 89 women had HSIL cytology; again, 82 had CIN2/3 (92.1%; 95% CI, 84.3%-96.4%). CONCLUSION There was good agreement between a positive urine test for high-risk HPV DNA genotypes and pathologic findings of CIN2/3.

Abstract
With the introduction of Human papillomavirus (HPV) vaccination in young girls in 2007, it is important to monitor HPV infections and epidemiological changes in this target population. The present study has evaluated the detection of human papillomavirus DNA in paired cervical and urine samples to understand if HPV testing in urine could be used as non-invasive method to monitor HPV status in young women. The study enrolled 216 twenty five-year-old women, resident in Florence and invited for the first time to the cervical cancer Screening Program within a project evaluating the impact of HPV vaccination. HPV genotyping was performed on 216 paired urine and cervical samples. The overall concordance between cervix and urine samples, investigated by HPV genotyping (INNO-LiPA HPV Genotyping Extra), was: 85.6% (184/215), 84.6% (182/215), 80% (172/215) when the same HPV, at least the same HR HPV and all HR HPV, respectively, were detected. HPV type specific concordance in paired urine and cervical samples was observed in 85.8% (175/204) of women with normal cytology and in seven out of nine women with abnormal cytology. Urine seems to be a suitable and reliable biological material for HPV DNA detection as evidenced by the high concordance with HPV detected in cervical samples. These results suggest that urine could be a good noninvasive tool to monitor HPV infection in vaccinated women.

Abstract
BACKGROUND Human papillomavirus (HPV) is the main cause of cervical cancer. The development of non-invasive self-sample collection methods would have the potential advantage of increasing the acceptance of the screening procedures. OBJECTIVES To compare human papillomavirus (HPV) DNA detection and genotyping with the Cobas 4800 HPV test (Roche Diagnostic, Spain) on paired cervical and first voided urine. STUDY DESIGN Paired urine and cervical samples were collected from 125 women referred for evaluation of abnormal Pap smear results. RESULTS The overall percent agreement between HPV detection in urine and cervical samples was 88%. A substantial concordance rate of HPV DNA detection in both samples was observed (κ=0.76; 95% IC: 64-87). In this high prevalence population the sensitivity, specificity, NPV and PPV for detection of HPV DNA from urine versus cervical samples were 90.5% (95% IC: 80-95%), 85%, (95% IC: 74-92%), 89.8% (95% IC: 79.5-95.3) and 86.4% (95% IC: 76.1-92.7) respectively. Compared to histologically confirmed CIN 2/3 disease, the clinical sensitivity and specificity for the detection of high-risk HPV in urine samples were 95% (95% IC: 76-97%) and 52.4% (95% IC: 40-64%) respectively. CONCLUSIONS These results suggest that urine samples processed with Cobas 4800 HPV test may be useful for clinical management of HPV infection.

Abstract
OBJECTIVE To determine the accuracy of testing for human papillomavirus (HPV) DNA in urine in detecting cervical HPV in sexually active women. DESIGN Systematic review and meta-analysis. DATA SOURCES Searches of electronic databases from inception until December 2013, checks of reference lists, manual searches of recent issues of relevant journals, and contact with experts. ELIGIBILITY CRITERIA Test accuracy studies in sexually active women that compared detection of urine HPV DNA with detection of cervical HPV DNA. DATA EXTRACTION AND SYNTHESIS Data relating to patient characteristics, study context, risk of bias, and test accuracy. 2 × 2 tables were constructed and synthesised by bivariate mixed effects meta-analysis. RESULTS 16 articles reporting on 14 studies (1443 women) were eligible for meta-analysis. Most used commercial polymerase chain reaction methods on first void urine samples. Urine detection of any HPV had a pooled sensitivity of 87% (95% confidence interval 78% to 92%) and specificity of 94% (95% confidence interval 82% to 98%). Urine detection of high risk HPV had a pooled sensitivity of 77% (68% to 84%) and specificity of 88% (58% to 97%). Urine detection of HPV 16 and 18 had a pooled sensitivity of 73% (56% to 86%) and specificity of 98% (91% to 100%). Metaregression revealed an increase in sensitivity when urine samples were collected as first void compared with random or midstream (P=0.004). LIMITATIONS The major limitations of this review are the lack of a strictly uniform method for the detection of HPV in urine and the variation in accuracy between individual studies. CONCLUSIONS Testing urine for HPV seems to have good accuracy for the detection of cervical HPV, and testing first void urine samples is more accurate than random or midstream sampling. When cervical HPV detection is considered difficult in particular subgroups, urine testing should be regarded as an acceptable alternative.

Abstract
BACKGROUND Cervical cancer is the second most common cancer in Thai women after breast cancer. Currently, the Papanicolaou (Pap) smear is the recommended procedure for cervical cancer screening in Thailand, but only a relatively small percentage of women follow this screening program. An alternative method to detect HPV genotypes associated with cervical cancer is self-sampling of urine, which is a more widely accepted method. Our study aimed to evaluate the prevalence of HPV in Thai women using urine and cervical swabs and prevalence of HPV in Thai men using urine samples. MATERIALS AND METHODS Tumorigenic HPV detection was accomplished by electrochemical DNA chip and PCR/direct sequencing. In addition to HPV prevalence, we report the concordance between different methods and sample types. One-hundred and sixteen women and 100 men were recruited. Histological examination revealed normal cytology in 52 women, atypical squamous cells of undetermined significance (ASCUS) in 9, low-grade squamous intraepithelial lesions (LSIL) in 24, and high-grade squamous intraepithelial lesions (HSIL) in 31. One-hundred men were classified as heterosexuals (n=45) and homosexuals (n=55). RESULTS The most prevalent HPV genotype in our study was HPV16. The HPV detection rate was generally lower in urine samples compared with cervical samples. Overall, there was good agreement for the detection of carcinogenic HPV from female cervical samples between the DNA chip and PCR/ sequencing, with 88.8% total agreement and a kappa value of 0.76. In male urine samples, the level of agreement was higher in heterosexuals compared with homosexuals. CONCLUSIONS Further improvement is required to increase an overall yield of HPV DNA detection in urine samples before clinical application of a urine-based HPV screening program. The electrochemical DNA chip test is a promising technique for carcinogenic HPV detection.

Abstract
Background HIV infection leads to a decreasing immune response, thereby facilitating the appearance of other infections, one of the most important ones being HPV. However, studies are needed for determining associations between immunodeficiency caused by HIV and/or the presence of HPV during the course of cervical lesions and their degree of malignancy. This study describes the cytological findings revealed by the Papanicolaou test, laboratory characteristics and HPV molecular profile in women with and without HIV infection. Methods A total of 216 HIV-positive and 1,159 HIV-negative women were invited to participate in the study; PCR was used for the molecular detection of HPV in cervical samples. Statistical analysis (such as percentages, Chi-square test and Fisher’s exact test when applicable) determined human papillomavirus (HPV) infection frequency (single and multiple) and the distribution of six types of high-risk-HPV in women with and without HIV infection. Likewise, a logistic regression model was run to evaluate the relationship between HIV-HPV infection and different risk factors. Results An association was found between the frequency of HPV infection and infection involving 2 or more HPV types (also known as multiple HPV infection) in HIV-positive women (69.0% and 54.2%, respectively); such frequency was greater than that found in HIV-negative women (44.3% and 22.7%, respectively). Statistically significant differences were observed between both groups (p = 0.001) regarding HPV presence (both in infection and multiple HPV infection). HPV-16 was the most prevalent type in the population being studied (p = 0.001); other viral types had variable distribution in both groups (HIV-positive and HIV-negative). HPV detection was associated with <500 cell/mm3 CD4-count (p = 0.004) and higher HIV-viral-load (p = 0.001). HPV-DNA detection, <200 cell/mm3 CD4-count (p = 0.001), and higher HIV-viral-load (p = 0.001) were associated with abnormal cytological findings. Conclusions The HIV-1 positive population in this study had high multiple HPV infection prevalence. The results for this population group also suggested a greater association between HPV-DNA presence and cytological findings. HPV detection, together with low CD4 count, could represent useful tools for identifying HIV-positive women at risk of developing cervical lesions.

Abstract
BACKGROUND Cervical cancer is caused by persistent infection with high-risk human papillomavirus (HR-HPV). Conventional human papillomavirus (HPV) testing requires cervical sampling. However, vaginal and urine self-sampling methods are more acceptable for patients and result in increased participation when they are available in screening programs. In this context, we have developed a non-invasive screening method via the detection of HPV DNA in urine samples. PURPOSE To compare HPV viral loads and genotypes in paired cervical and urine samples, and to assess correlation between virological and cytological results in women seeking gynecological consultation. METHODS Paired urine and cervical specimens were collected and analyzed from 230 of 245 women participating in the previously described prospective PapU study. HPV DNA detection and quantification were performed using a real-time PCR method with short fragment PCR primers. Genotyping was carried out using the INNO-LiPA HPV genotyping assay. RESULTS The prevalence of HPV in the 230 paired urine and cervical smear samples was 42 and 49 %, respectively. Overall agreement for HPV positivity and negativity between the paired samples was 90 % (κ = 0.80). High HPV viral load in both cervical and urine samples was associated with cytological abnormalities. HPV-positive women were mostly infected with HR-HPV types. The agreement between high- and low-risk HPV (LR-HPV) detection in both samples was 97 % (κ = 0.95 for HR-HPV and κ = 0.97 for LR-HPV). CONCLUSIONS High concordance rates for HPV-DNA quantification and high/low-risk HPV genotyping in paired urine/cervical samples suggest that urinary HPV DNA testing could be useful for cervical lesion screening.

Abstract
Human papillomavirus (HPV) is the main risk factor associated with the development of cervical cancer (CC); however, there are other factors, such as immunosuppression caused by the human immunodeficiency virus (HIV), that favor progression of the illness. This study was thus aimed at evaluating the functionality of classical PCR-based molecular tests for the generic identification of HPV DNA (GP5+/GP6+, MY09/MY11, and pU1M/2R primers, individually or in combination) using cervical and urine samples from 194 HIV-positive women. Infected samples were tested with type-specific primers for six high-risk types (HPV-16, -18, -31, -33, -45, and -58) and two low-risk types (HPV-6 and -11). HPV infection prevalence rates were 70.1% for the cervical samples and 63.9% for the urine samples. HPV-16 was the most prevalent viral type in the cervical and urine samples, with higher rates of multiple infections than single infections detected in such samples. HPV DNA detection by PCR (mainly with the pU1M/2R primer set) in urine samples was positively associated with abnormal cytological findings (atypical squamous cells of undetermined significance/squamous intraepithelial lesions [ASCUS/SIL]). It was determined that the operative characteristics for detection of cytological abnormalities were similar for cervical and urine samples. This suggested using PCR for the detection of HPV DNA in urine samples as a potential screening strategy for CC prevention in future prevention and control programs along with currently implemented strategies for reducing the impact of the disease, i.e., urine samples are economical, are easy to collect, have wide acceptability among women, and have operative characteristics similar to those of cervical samples.

Abstract
Infection, coinfection and type-specific human papillomavirus (HPV) distribution was evaluated in human immunodeficiency virus (HIV)-positive women from paired cervical and urine samples. Paired cervical and urine samples (n = 204) were taken from HIV-positive women for identifying HPV-DNA presence by using polymerase chain reaction (PCR) with three generic primer sets (GP5+/6+, MY09/11 and pU1M/2R). HPV-positive samples were typed for six high-risk HPV (HR-HPV) (HPV-16, -18, -31, -33, -45 and -58) and two low-risk (LR-HPV) (HPV-6/11) types. Agreement between paired sample results and diagnostic performance was evaluated. HPV infection prevalence was 70.6% in cervical and 63.2% in urine samples. HPV-16 was the most prevalent HPV type in both types of sample (66.7% in cervical samples and 62.0% in urine) followed by HPV-31(47.2%) in cervical samples and HPV-58 (35.7%) in urine samples. There was 55.4% coinfection (infection by more than one type of HPV) in cervical samples and 40.2% in urine samples. Abnormal Papanicolau smears were observed in 25.3% of the women, presenting significant association with HPV-DNA being identified in urine samples. There was poor agreement of cervical and urine sample results in generic and type-specific detection of HPV. Urine samples provided the best diagnosis when taking cytological findings as reference. In conclusion including urine samples could be a good strategy for ensuring adherence to screening programs aimed at reducing the impact of cervical cancer, since this sample is easy to obtain and showed good diagnostic performance.

Abstract
The ability to detect type-specific high risk HPV (HR-HPV) infections in samples from females and males is important for monitoring the epidemiology of HPV and the impact of vaccination. Type-specific detection concordance between paired urine and genital samples from females (n = 264) undergoing routine colposcopy and males (n = 88) attending a genito-urinary medicine clinic was evaluated using an in-house genotyping assay. The overall inter-rater agreement (κ) was 0.781 for female pairs and 0.346 for male pairs. Female urine had sensitivity for detection of HPV16/18 and HR-HPV of 75% and 84%, respectively, while male urine had sensitivities of 13% and 28%, respectively. Genital samples had a higher HPV DNA copy number than urine although a small proportion (10%) of urine samples had a higher copy number than the corresponding genital sample. The proportion of females with normal cytology positive for HPV16/18 was 19%, increasing to 57% in moderate or severely dyskaryotic samples. The same trend was seen in the corresponding urine (19-43%) compounded by the reduced sensitivity of this sample type. The HPV16 viral load in female genital samples, but not in urine, was weakly associated with cervical disease stage. Despite reduced sensitivity, urine appears to be an appropriate surrogate sample for type-specific HPV detection in females for epidemiological objectives. The lower sensitivity and lack of association between viral load and disease stage in urine suggest that urine may not be useful for clinical management of HPV infection. The utility of urine for type-specific detection in males is less certain.

Abstract
The detection of human papillomavirus (HPV) DNA in urine, a specimen easily obtained by a non-invasive self-sampling method, has been the subject of a considerable number of studies. This review provides an overview of 41 published studies; assesses how different methods and settings may contribute to the sometimes contradictory outcomes; and discusses the potential relevance of using urine samples in vaccine trials, disease surveillance, epidemiological studies, and specific settings of cervical cancer screening. Urine sampling, storage conditions, sample preparation, DNA extraction, and DNA amplification may all have an important impact on HPV DNA detection and the form of viral DNA that is detected. Possible trends in HPV DNA prevalence in urine could be inferred from the presence of risk factors or the diagnosis of cervical lesions. HPV DNA detection in urine is feasible and may become a useful tool but necessitates further improvement and standardization.

Abstract
In this article we aim to draw attention to the burden of cervical cancer in Africa for reproductive health and review strategies for prevention, including appropriate noncytology-based cervical screening and prophylactic human papillomavirus vaccination. We consider the heavy burden of disease attributable to human papillomavirus infection borne by developing countries, particularly in Africa. Following identification of the human papillomavirus as the infectious etiological agent and elucidation of the long natural history of cervical neoplasia, cervical cancer is now one of the most preventable of all cancers. Opportunities for primary prevention by prophylactic vaccination and secondary prevention by appropriate cervical screening are discussed, together with the importance of population coverage. Qualitative work on attitudes towards cervical cancer prevention, education needs, the creation of an environment for informed choice and uptake are essential aspects of effective prevention programs. Cervical cancer poses a huge health burden in Africa. It is a disease that is eminently preventable given political will, the availability of affordable vaccines, appropriate cervical screening and access to cheap, point-of-care human papillomavirus testing. There are a number of unanswered questions for the prevention of cervical cancer and a need for demonstration projects to address these and further develop prevention strategies.

Abstract
OBJECTIVES The present study aimed to evaluate type specific Human Papillomavirus (HPV) strains in women with different clinical manifestations but with normal cervical cytology, attending a gynecology out patient clinic and HPV infection in males attending a private pathology laboratory for routine check up in Mumbai. METHODS Cervical swab specimens from 470 women with normal cervical cytology as detected by Pap were used for detection and typing of HPV by PCR, southern blotting and sequencing. In 104 males, 30 ml of first void/random urine specimens were used for HPV screening. RESULTS Thirty-eight women (8.1%) tested positive for HPV. HPV 16, 18, 6, 11 and mixed infection was observed in 26.3%, 10.5%, 36.8%, 5.2% and 15.8% of these infected women, respectively, while 36.8% had other HPV types, indicating high rate of high-risk HPV types 16/18. Among the 104 males, 12 (11.5%) had HPV infection, 50% (n=6) of them were below 30 years. Nine of them were married and three were unmarried. CONCLUSIONS The present study revealed presence of high risk HPV infection in women with normal cervical cytology. This is the first report from the Western region of India on HPV infection in males using urine specimen.

Abstract
Oncogenic types of human papilloma viruses (HPVs) have been established to be the causative agents for cervical cancers and high-grade squamous intraepithelial lesions (HSILs). The clinical application of molecular tests for HPV detection for screening purposes has been of considerable interest. DNA amplification methods allow the use of self-collected samples (including urine) from material collected away from the original disease site. For screening of cervical pathology, detection of HPV-DNA in urine would be useful only if it represents cervical HPV infection and/or HPV-related cervical pathology. We conducted a review of the literature in order to ascertain: (1) if urine is an adequate sample for HPV-detection; (2) whether sensitive techniques are available for HPV-detection in urine and (3) if detection of HPV in urine truly represents cervical infection/pathology. The review process consisted of assembling facts and analysing the published literature on the following facts: anatomical considerations of the lower genital and the lower urinary tract, biological behaviour of HPV and its shedding behaviour, technical issues regarding sample collection, processing and HPV-DNA assay systems, concordance rates of HPV-DNA detection and their type specificity in the paired samples (urine and cervical scrapes) obtained in different clinico-epidemiological settings and comparative detection rates of HSILs in the paired samples.

Abstract
HIV-infected patients are at increased risk for persistent human papillomavirus (HPV) infection, the major cause of anogenital cancer. The present study describes the HPV prevalence in urine samples of 243 HIV-infected men and a control group of 231 men. HPV DNA was amplified by the SPF10 polymerase chain reaction primer set. The overall HPV prevalence in HIV-infected men was 27.5% compared with 12.6% in controls (P < 0.01). Infections with high-risk and multiple HPV genotypes were present in both groups. Differences were not statistically significant. A multivariate logistic regression model showed a decreased HPV prevalence associated with use of a nucleoside and a non-nucleoside reverse transcriptase inhibitor combination (P = 0.03). A trend was observed towards a higher HPV prevalence and a lower CD4 cell count. Further prospective studies are needed to determine the role of HPV DNA testing in urine in future screening programmes for anal cancer in men.

Abstract
PURPOSE Global data on age-specific prevalence of human papillomavirus (HPV) infection overall, and for high-risk HPV types 16 and 18, are essential for the future implementation of HPV prophylactic vaccines for cervical cancer prevention. METHODS A systematic review of peer-reviewed publications was conducted to summarize worldwide data on genital HPV-DNA prevalence in women. Studies with clear descriptions of polymerase chain reaction or hybrid capture detection assays were included. RESULTS A total of 346,160 women were included in 375 studies. Of 134 studies with age-stratified HPV prevalence data (116 low sexual risk populations, 18 high sexual risk populations), over 50% were from Europe and the Middle East (38%) and North America (19%), with smaller proportions from Asia and Australia (21%), Central and South America (11%), and Africa (10%). Across all geographical regions, data on HPV prevalence were generally limited to women over 18 years of age. Consistently across studies, HPV infection prevalence decreased with increasing age from a peak prevalence in younger women (< or =25 years of age). In middle-aged women (35-50 years), maximum HPV prevalence differed across geographical regions: Africa (approximately 20%), Asia/Australia (approximately 15%), Central and South America (approximately 20%), North America (approximately 20%), Southern Europe/Middle East (approximately 15%), and Northern Europe (approximately 15%). Inconsistent trends in HPV prevalence by age were noted in older women, with a decrease or plateau of HPV prevalence in older ages in most studies, whereas others showed an increase of HPV prevalence in older ages. Similar trends of HPV 16 and/or 18 prevalence by age were noted among 12 populations with available data. DISCUSSION Genital HPV infection in women is predominantly acquired in adolescence, and peak prevalence in middle-aged women appears to differ across geographical regions. Worldwide variations in HPV prevalence across age appear to largely reflect differences in sexual behavior across geographical regions. Further studies of HPV prevalence in adolescents are needed for all geographic regions.

Abstract
BACKGROUND HIV-infected women are at increased risk for cervical dysplasia. Cervical dysplasia is caused by persistent infections with certain types of human papillomavirus (HPV). Conventional testing for genital HPV infections requires cervical cytology. A non-invasive screening method by detection of HPV DNA in urine samples is preferable but is not a routine practice. OBJECTIVES To investigate the prevalence and concordance of HPV in paired urine and cervical smear samples and cytological results of Pap smears in HIV-infected women. STUDY DESIGN Paired urine and cervical smear samples were collected from 27 HIV-infected women. RESULTS The HPV prevalence in urine and cervical smear samples was 81.5% and 51.9%, respectively (p = 0.01). The concordance for HPV positivity and negativity between urine and cervical smear samples is 71%. Seven women (25.9%) had an abnormal cervical smear of Pap II or higher. In all urine samples from these cases HPV DNA was detected. CONCLUSION In the present study we show that the HPV prevalence in urine and cervical smear samples of HIV-infected women is high and HPV test results are highly concordant. Therefore, urine samples can be used as medium for HPV testing. HPV testing in urine samples is a simple, reliable, non-invasive screening method.

Abstract
We examined the feasibility of using detection of high-risk human papillomavirus (HPV) DNA in combination with the presence of aberrantly methylated genes (DAPK1, RARB, TWIST1, and CDH13) for urine-based cervical cancer screening. Urine samples from 129 Senegalese women, aged 35 years or older, 110 with (same day) biopsy-proven cervical neoplasia [cervical intraepithelial neoplasia grade 1 (CIN-1): n = 9; CIN-2-3/carcinoma in situ (CIS): n = 29; invasive cervical cancer (ICC): n = 72], and 19 without cervical neoplasia on biopsy were examined. Hypermethylation of at least one of the four genes identified 62% of ICC and 28% of CIN-2-3/CIS and was present in only 4% of CIN-1 or normal urines. High-risk HPV DNA was detected in urine in 70% of those with biopsy-proven ICC, 59% of those with CIN-2-3/CIS on biopsy, 44% of those with CIN-1 on biopsy, and only 11% of women negative for cervical neoplasia on biopsy. Urine-based detection of either high-risk HPV or hypermethylation of any of the four genes identified 84% of ICC, 64% of CIN-2-3/CIS, 44% of CIN-1, but only 19% of women negative for cervical neoplasia. The sensitivity for detection of CIN-2-3/CIS/ICC by high-risk HPV DNA or aberrant DNA methylation of four genes seems to be comparable to that of an exfoliated cervical cytology. This study shows the potential feasibility of using molecular markers detected in urine for cervical cancer screening.

Abstract
AIM To 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. METHODS In 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. RESULTS beta-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. CONCLUSION Urine 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.

Abstract
OBJECTIVES To investigate the usefulness of human papillomavirus detection in the urine of women with poor gynecologic attention. MATERIALS AND METHODS Fifty urine and 50 cervical samples from 50 women were analyzed. Polymerase chain reaction was performed on these 100 samples using consensus primers and a low-density microarray-based method for human papillomavirus typing. RESULTS The concordance of the results between both sample groups was 80%. In the urine samples, the sensitivity of polymerase chain reaction for high-grade squamous intraepithelial lesion was 100%, the specificity was 80%, the positive predictive value was 91%, and the negative predictive value was 100%. CONCLUSIONS Human papillomavirus detection in urine samples may be used as an alternative screening method for women with poor gynecologic attention.

Abstract
A considerable number of adult Korean women avoid a Pap smear due to fear and discomfort of the pelvic examination. A reliable but noninvasive and comfortable screening method would considerably increase the participation rate. To evaluate the clinical efficacy of urine-based human papillomavirus (HPV) detection by oligonucleotide microarray, the results of HPV test from matched cervical swab specimens were compared. HPV DNA was detected in 70 of 100 cervical samples. HPV 16 was the most prevalent type (38/70), followed by types 18, 58, 52, 33, 35, 31, and 51. HPV DNA was identified in 47 of 90 urine samples. HPV 16 was the most prevalent type (30/45), followed by types 18, 52, 35, 51, 58, 33, and 56. The HPV detection rates of the cervical swabs increased in accordance with the severity of the cytologic and histologic diagnosis. The type specific agreement of HPV DNA tests between cervical swabs and urine was good in HPV 16 (kappa index=0.64 [95% CI: 0.50-0.79]), 18, 52, and 58 and fair in HPV 33 and 35. We propose that a urine HPV test is a valuable adjunctive method for a conventional Pap smear and can be used in population screening for cervical cancer in countries where it is difficult to obtain colposcopic specimens for cultural or religious reasons.

Abstract
During the last decade, growing efforts have focused on human papillomavirus (HPV) detection using liquid hybridization, conventional PCR, and real-time PCR-based methods to increase the overall proportion of patients participating in cervical cancer screening procedures. We proposed a new general HPV DNA real-time PCR on the Mx4000 (Stratagene) and LightCycler (Roche Diagnostics) systems usable for both cervical scrape specimens and urine samples. A linear range was obtained from 5 DNA copies to 8 log(10) DNA copies/ml, and intra- and interassay variations were between 1.8 and 4%. Cervical carcinoma and HPV DNA screening was performed in 333 individual women referred for gynecological examination at the university hospitals of Angers and Brest and enrolled in the PapU study. Among cervical specimens (n = 333), 45% were positive for HPV DNA, with a mean viral load at 5.00 log/ml (+/- 1.73). Among urine samples (n = 177), 37% were positive with a significant 50-fold-lower mean viral load (3.77 +/- 1.32 log/ml; P < 0.0001). Kappa agreement for HPV DNA between cervical and urine specimens was excellent (93%). Thus, we developed a highly sensitive and quantitative general HPV DNA real-time PCR method that allows mass screening of patients with HPV infection. The ongoing longitudinal and prospective multicenter PapU study should give us the opportunity to validate this method adapted to HPV DNA screening in urine samples in a larger population.

Abstract
HPV infection of both the genital tract and oral cavity of HIV+ men and women is increased. HPV-related pathology is also increased in the HIV+ individuals, usually with further increases seen for those HIV+ individuals with lower CD4 cell counts. Fortunately, the rates of cervical cancer and anal cancer are relatively low and not related to CD4 cell count. Treatment of the HIV+ individual with HPV-related disease is challenging and requires close long-term follow-up to prevent recurrent disease. The mechanism of how HPV and HIV interact is still not known but is more likely to be linked to immune suppression rather than a direct interaction between viruses. The newly developed HPV vaccines will likely have a significant impact on HPV-related disease in immunocompetent individuals. It remains to be seen what impact these vaccine will have on the immune depressed.

Abstract
Infection of specific types of high-risk human papillomaviruses (HPVs) causes cervical cancer in women. Conventional test for genital HPV infection requires collection of scraped cervical cells or biopsy specimens, which involves invasive procedures. Utility of non-invasive urine sampling for detection of HPV in women and their male sexual partners is controversial. The validation of this urine-based HPV DNA test is of immense value not only in screening large population and children but also for HPV vaccine monitoring in adolescents. We examined the frequency of high risk HPV types 16 and 18 in simultaneously collected urine samples and cervical scrapes or biopsy specimens from women with cervical cancer and their single lifetime male sexual partners in order to validate the utility of urine sampling as a reliable non-invasive method for detection of genital HPV infection. Thirty women with invasive cervical cancer and their husbands along with 30 age-matched normal healthy women including their husbands were recruited for the study. Cervical biopsies/scrapes from women subjects and penile scrapes from their husbands and urine samples from all of them were collected before taking biopsy or scrapes. HPV-L1 consensus primer as well as high-risk HPV (HPV 16 and 18) type-specific oligo-primers were used for PCR detection of HPV DNA. The total frequency of HPV in women with cervical cancer was found to be 83% (25/30) while it was only 67% (20/30) in their male partners but there was virtually no difference in results between urine and scrape or tissue biopsy either in women or their male partners. Although healthy women and their husbands showed similar frequency of HPV infection both in urine and scrape samples, there was a significant difference (p=0.05) in the prevalence of high risk HPV type 16 in women with cervical cancer (70%) and their male partners (30%). Similar was the trend between control women and their male partners. The results also showed a very high prevalence of HPV type 16 among Indian women with cervical cancer while its frequency was significantly low in their single lifetime male partners. The case by case matching of HPV positivity and negativity between urine and cervical/penile scrapes or biopsies obtained from women and their male partners demonstrated that the non-invasive urine sampling can be reliably used for screening genital HPV infection in both men and women.

Abstract
This study was conducted to determine the prevalence and distribution of Chlamydia trachomatis genotypes in Taiwan. Urine and endocervical-swab samples were collected from two hospitals located in northern and southern Taiwan. The genotypes of a total of 145 samples positive for C. trachomatis were analysed by sequencing the omp1 gene and this was successful in 102 samples. Nine different C. trachomatis genotypes were identified. Genotype E was the most prevalent (22 %), followed by D and Da (19 %), F (16 %), J (15 %), K (11 %), G (11 %), H (6 %) and Ba (2 %). There was a geographical difference in the prevalence of genotype H (P < 0.018) between northern and southern Taiwan. Sequence mutation analysis by blast searching against GenBank reference sequences identified 12 genetic variants from a total of 102 omp1 gene sequences.

Abstract
OBJECTIVE To determine the association between female genital Schistosoma haematobium infection and HIV. DESIGN AND METHODS A cross-sectional study with a 1-year follow-up. Gynecological and laboratory investigations were performed for S. haematobium and HIV. Sexually transmitted infections, demographic and urogenital history were analysed as confounders. The participants were 527 sexually active, non-pregnant, non-menopausal women between the ages of 20 and 49 years. The setting was a rural Zimbabwean community where S. haematobium related lesions were found in 46% of the women, HIV in 29% and herpes simplex type- 2 (HSV-2) in 65%. RESULTS In permanent residents (>3 years residency), HIV was found in 41% (29/70) of women with laboratory proven genital schistosomiasis as opposed to 26% HIV positive (96/375) in the schistosomal ova negative group [odds ratio (OR), 2.1; 95% confidence interval (CI), 1.2-3.5; P = 0.008. In multivariate analysis S. haematobium infection of the genital mucosa was significantly associated with HIV seropositivity (adjusted OR, 2.9; 95% CI, 1.11-7.5; P = 0.030). All seven women who became HIV positive during the study period (seroincidence 3.1%) had signs of S. haematobium at baseline. In accordance with other studies HIV was significantly associated with HSV-2 (OR, 3.0; 95% CI, 1.7-5.3; P < 0.001), syphilis and human papillomavirus. The highest HIV prevalence (45%) was found in the 25-29 years age group. CONCLUSION Women with genital schistosomiasis had an almost three-fold risk of having HIV in this rural Zimbabwean community. Prospective studies are needed to confirm the association.

Abstract
Infection with human immunodeficiency virus (HIV) and the resulting immunosuppression are associated with an increased risk for human papillomavirus (HPV) persistence and related malignancies. In the present study we investigated the prevalence of HPV in urine samples from 104 HIV-infected men with low CD4+ cell counts (<100 per mm(3)) and 115 urine samples from HIV-negative men. A high prevalence of HPV DNA (39.4%) was found in the HIV patients. Most of the HPV types were high risk (81.4%), with HPV 52 as the most prevalent type (12.5%), followed by HPV 18 (6.7%), HPV 35 (5.8%), and HPV 70 (4.8%). Multiple HPV genotypes were observed in 17 (41%) of the 41 HPV- and HIV-positive men. In contrast, only 11 (9.6%) HPV DNA-positive cases were observed among the 115 HIV-uninfected men, and 3 (27.3%) contained multiple genotypes. Quantitative analyses indicated that the HPV viral load, as measured in urine samples, is significantly higher in HIV-positive men compared to HIV-negative men. In the present study we show that urine samples are useful for detecting HPV DNA, there is a high prevalence of HPV in HIV-positive men, and the HPV viral load is substantially higher in HIV-positive than in HIV-negative men. More studies are needed to evaluate the risk and natural development of HPV-related malignancies in HIV-positive men.

Abstract
OBJECTIVE Non-invasive sampling of human genitals to identify high-risk individuals with subclinical oncogenic HPV infection remains a challenge. The study was designed to see if self-collected urine can be used as a simple, non-invasive sampling for screening HPV, particularly for screening/monitoring general population or young adolescents or infants, if they are to be immunized by HPV vaccines. METHOD Self-collected urine samples from 100 sexually unexposed college going girls and cervical scrapes from 104 normal healthy sexually active married women were used in this study. Additionally, a group of 55 women were recruited for collecting first urine and later scraped cervical cells to validate urine sampling by directly comparing HPV positivity between the two types of biological specimens. A dry 'paper smear' method for specimen collection and a simple single tube protocol was employed for PCR detection of HPV infection. RESULTS Out of 100 sexually inexperienced college going girls, only 6 (6%) were positive for HPV infection as revealed by L1 consensus primer and 4 (4%) of them were positive for HPV 16 but none was found positive for HPV 18 DNA. Out of 104 sexually active married women who were cytologically reported as negative by Pap test, 11 (10.5%) were found HPV positive and 7 (6.7%) of them had infection of high-risk HPV type 16. Both urine and later cervical scrapes from a group of 55 women collected as dry 'paper smear' showed perfect matching positivity for HPV between urine and cervical scrape. CONCLUSIONS The use of urine coupled with its dry collection as 'paper smear' facilitating their easy transport, storage and direct PCR detection of HPV DNA opens up an alternative non-invasive approach for population screening of HPV infection, at least in such cases as children and infants in whom invasive samples are difficult to obtain.

Abstract
PURPOSE OF REVIEW With the advent of highly sensitive and specific nucleic acid amplification assays, this report will demonstrate that self-collected genital specimens, such as urine or even vaginal swabs can be accurately used to diagnose sexually transmitted infections. RECENT FINDINGS Use of self collected samples can eliminate the necessity of a clinician to perform a pelvic examination for women or collect a urethral swab for men, thus extending the diagnostic capability for sexually transmitted infections to non-clinic screening venues. As many sexually transmitted infections are asymptomatic, this ability to use self-sampling greatly increases the numbers of patients that can be screened, and has the potential to augment public health programs designed to control the epidemic of sexually transmitted infections in the community. Patient collected samples are highly acceptable, highly accurate, and are becoming widely used. Self-sampling also allows clinicians to easily screen patients in the clinic, who are not presenting for pelvic or urogenital examinations, for sexually transmitted infections. SUMMARY Highly accurate molecular tests and easily obtained self-collected urogenital samples represent the ideal combination for obtaining the public health goal of decreasing the sexually transmitted infection epidemic among sexually active persons in the United States today.

Abstract
BACKGROUND Human papillomavirus (HPV) causes cervical cancer. Current screening requires a yearly pelvic exam and Pap smear. However, these procedures are impractical for screening all women at risk for disease. Urine sampling has been successfully utilized to screen for Chlamydia trachomatis (CT) and Neisseria gonorrhoreae (NG) infections and has been considered for HPV DNA detection by several investigators. However, no study to date has been performed to specifically optimize HPV detection in urine. OBJECTIVES To compare handling and extraction techniques in order to optimize the HPV specific PCR system in urine specimens. STUDY DESIGN Examination of 10 characteristics that may contribute to PCR inhibition in urine was performed utilizing 10SG mulitstixs. Five different DNA extraction methods were compared in spiked specimens and in 10 clinical specimens. After the optimal extraction technique was identified, concentration of the sample with and without prior dilution was compared to the original protocol. Lastly, specimen handling was compared between immediate processing, refrigerating overnight, or freezing overnight. RESULTS AND CONCLUSIONS the presence of protein in urine enhanced amplification while nitrites decreased amplification. Of the extraction methods tested, the QIAamp DNA Mini Kit demonstrated the best amplification from urine samples spiked with HPV DNA and clinical specimens. The addition of a dilution step and a concentration step before applying the Qiagen protocol further increased amplification of beta-globin (from 50 to 63%) and the HPV L1 gene (from 13 to 33%). Lastly, refrigerating the specimens at 4 degrees C overnight appears to produce better amplification (62% beta-globin and 17% HPV positive) than either immediate processing (46% beta-globin and 13% HPV+) or freezing the specimen for 24h prior to processing (46% beta-globin and 10% HPV+). In these studies, amplification was low despite optimization. Additional improvements are required prior to clinical application of a urine-based HPV DNA detection system.

Abstract
Cervical cancer is a leading cause of cancer-related deaths in developing countries, and the human papillomavirus (HPV) is linked etiologically to cervical cancer. Hence, a vaccine which prevents HPV-associated cervical cancer would have the most impact in developing countries, including the African continent. The type-specific immune response towards HPV virus-like particles, in combination with geographical variation in the prevalence of HPV, necessitates the presence of multiple HPV type antigens in a single vaccine cocktail in order to provide relevant protection. We aimed to investigate whether co-infection with HIV, which is highly prevalent in Africa, plays a role in HPV genotype distribution. After informed consent, HPV detection by GP5+/6+ PCR and HIV detection by serology was carried out on 236 women from the rural north-western part of Zimbabwe. The prevalence of HPV was higher in HIV positive women (54%) than in HIV negative women (27%). Certain HPV types (HPV types 11, 39, 43, 51, and 59, P-values ranging from 0.017 to 0.067) occurred more frequently in HIV positive women. Only high-risk HPV, and not HIV, was associated significantly with cervical intraepithelial neoplasia in multiple regression analysis. In conclusion, a high prevalence of HPV was found in a rural community, where regular Papanicolaou (Pap) smears would be a logistic and economic impossibility, but where free vaccination programmes against other infections are already established. The results suggest that HIV co-infection may have an impact on HPV genotype distribution.

Abstract
OBJECTIVE To estimate the optimal relative light unit ratio, as a measure of viral load, of the Hybrid Capture II human papillomavirus (HPV) test in self-collected specimens for detecting cervical intraepithelial neoplasia (CIN). METHODS Two hundred women referred for colposcopy with abnormal cytologic, self-collected vaginal and vulvar swabs and urine for HPV testing. The receiver operating characteristic (ROC) curve method was used to estimate optimal cutoffs for the Hybrid Capture II test. The reference standard was colposcopy, with directed biopsy as required. RESULTS The estimated optimal cutoffs of the relative light unit ratio for detecting CIN 2 or higher for urine, vulvar, and vaginal samples gave sensitivities of 72.4%, 82.8%, and 89.0% and specificities of 57.0%, 52.1%, and 55.9%, respectively. At the manufacturer's recommended 1.0 cutoff, sensitivities were 44.8%, 62.1%, and 86.2% for urine, vulvar, and vaginal samples, with specificities of 69.7%, 62.7%, and 53.5%, respectively. The likelihood ratios (likelihood of being truly positive after a positive test result) were similar for the optimal and the 1.0 cutoff. CONCLUSIONS The ROC curve methods did not improve the overall diagnostic accuracy of the Hybrid Capture II test compared with the 1.0 relative light unit ratio cutoff.
