Abstract
Introduction Urological surgeries are a significant part of surgical services. The need for these services varies regionally and globally. Knowledge of the local need is important for prioritisation of resources. Objectives To describe the urological procedures done in our hospital for effective utilisation of the already scarce resource in this region. Patients and Methods This was a retrospective one-year study of the urosurgical cases done in a Nigerian Teaching Hospital. The main theatre register was used to collate data. Data collected included age, sex, operation done and anaesthesia employed. Results One hundred and twenty-two male and three female patients were included with a male-to-female ratio of 41:1. The mean age of the patients was 56.6 ± 19.89 years. Elective cases accounted for 102 (81.6%) of surgeries. Regional anaesthesia was the most common form of anaesthesia accounting for 105 (84%) followed by local anaesthesia in 16 (12.8%). Day cases accounted for 77 (61.6%) of procedures. More than 80% of the study population was 50 years and older. Overall, the three most common performed surgeries were digital-guided prostate biopsy 47 (37.6%), suprapubic cystostomy 16 (12.8%) and open prostatectomy 9 (7.2%). In male patients, the three most common procedures were prostate biopsy 47 (38.5%), suprapubic cystostomy 16 (13.1 %), open prostatectomy 9 (7.4%) whereas nephrectomy, pyeloplasty and stent removal each accounted for 33.3% each of procedures in female patients. Endourological procedures accounted for 5 (4%) of cases. Conclusion Open surgeries accounted for the majority of these cases done with prostate-related procedures being the most common procedures. Few endourological procedures were performed.

Li J, Xie H, Fu L, Guo X, Dong J, Xu M, Wang G, Zhao A. Comparison of the Immune Responses to Different Formulations of BC02-Adjuvanted HPV Types 16 and 18 Bivalent Vaccines in Mice. Vaccines (Basel) 2023; 11:1553. [PMID: 37896956 PMCID: PMC10611034 DOI: 10.3390/vaccines11101553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/25/2023] [Accepted: 09/28/2023] [Indexed: 10/29/2023] Open
Abstract
To achieve maximum efficacy, vaccines, such as subunit, recombinant, and conjugate vaccines, necessitate the incorporation of immunostimulators/adjuvants. Adjuvants play a vital role in bolstering and extending the strength of the immune response while also influencing its type. As antigen and adjuvant formulations become more intricate, it becomes imperative to establish a well-characterized and robust formulation to ensure consistent and reproducible outcomes in preclinical and clinical studies. In the present study, an HPV bivalent vaccine was developed using a BC02 adjuvant in conjunction with HPV 16 and 18 L1 VLP antigens produced from an E. coli expression system. The study involved evaluating the adjuvant formulation and in vivo immunogenicity in mice. Remarkably, a medium-dose of BCG-CpG-DNA combined with a low-dose of aluminum hydroxide substantially enhanced the immunogenicity of HPV16 and 18 VLPs, resulting in improved cellular and humoral immune responses.

[PMID: 37700831 PMCID: PMC10493382 DOI: 10.3389/fonc.2023.1264114] [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: 07/20/2023] [Accepted: 08/08/2023] [Indexed: 09/14/2023] Open
Abstract
Background This study aimed to investigate the differences in long-term oncological outcomes between high-risk human papillomavirus (HR-HPV) negative and HR-HPV positive early-stage cervical cancers. Methods We retrospectively analysed 2061 cases of early-stage cervical cancer from the Chinese cervical cancer clinical diagnosis and treatment database. Kaplan-Meier curves were used to describe the survival outcomes of different HR-HPV infections. Cox proportional hazard regression model was used to analyze and determine independent risk factors. Results K-M analysis revealed no significant difference in 5-year OS between HR-HPV negative and HR-HPV positive groups (OS: 95.0% vs.95.6%, P=0.900). A significant difference was observed in 5-year DFS between the HR-HPV negative and HR-HPV positive groups (DFS: 87.2% vs.91.9%, P=0.025). Cox proportional hazard regression model indicated that HR-HPV infection (negative vs. positive) was an independent factor influencing 5-year DFS after early cervical cancer surgery (DFS: hazard ratio [HR]=1.862, P=0.022). HR-HPV infection (negative vs positive) was not an independent factor influencing 5-year OS after early cervical cancer surgery (OS: P=0.813). After 1:1 PSM pairing, there was no significant difference in 5-year OS and DFS between HR-HPV negative group and HR-HPV positive group (OS: 91.6% vs.95.0%, P=0.297; DFS: 87.2% vs.85.1%, P=0.758). Cox multivariate analysis indicated that HR-HPV infection was not an independent factor influencing 5-year OS and DFS after early cervical cancer surgery (OS: P=0.806, DFS: P=0.251). Conclusions The tumour results of HR-HPV negative group and HR-HPV positive group were similar, after eliminating the differences in known variables that affect the oncological outcomes of cervical cancer. The treatment plan of HR-HPV positive cervical cancer is suitable for HR-HPV negative cervical cancer.

Abstract
BACKGROUND Lichen sclerosus (LS) is an inflammatory disease mostly arising at the genital level. It is unclear whether human papillomaviruses (HPVs) have an etiological significance in LS, and data on their prevalence in patients with LS are controversial. OBJECTIVES The authors assessed alpha, beta, and gamma HPV prevalence in patients with genital LS. The association of HPV positivity with demographic and clinical factors was also investigated. METHODS One hundred thirty-two formalin-fixed, paraffin-embedded LS samples (2016-2020) were retrieved from the archives of a pathology department. Alpha HPVs were genotyped with the INNO-LiPA HPV Genotyping Extra II kit. Beta and gamma HPVs were searched by multiplex Polymerase Chain Reaction. Immunostaining for p16 INK4a was performed on high-risk HPV-positive samples. RESULTS Patients had a median age of 61 years, were mostly women ( n = 73, 55.3%), and with an early disease stage ( n = 79, 59.8%). Alpha HPVs were detected in 12/132 cases (9.1%). Among the 5 high-risk HPV-positive cases, only 2 displayed a strong and diffuse p16 INK4a staining. Beta genus was the most prevalent (35/132, 26.5%) and HPV5 was the most frequent beta genotype (25/132, 18.9%). There were 3 gamma HPV-positive cases among those with a valid result (3/131, 2.3%). Multiple infections with genotypes belonging to different genera were infrequent (3/131, 2.3%). No significant differences in the prevalence of the individual genera were observed according to sex and disease stage. CONCLUSIONS Of the 3 HPV genera, beta genus showed the highest prevalence. Further research is needed to clarify whether the presence of beta HPVs in genital LS has a clinical significance.

Abstract
INTRODUCTION Prostate cancer (CaP) is the second most common cancer in men and the fifth most common cancer worldwide. The incidence in Nigeria is rising. Numerous challenges exist that prevent the successful management of these patients in this subregion. AIMS AND OBJECTIVES This study aimed to report on the modes of presentation and difficulties encountered in managing patients with CaP in our environment with a view to finding solutions to these challenges. MATERIALS AND METHODS This was a retrospective study of all CaP patients who were managed in Alex-Ekwueme Federal University Teaching Hospital, Abakaliki, Ebonyi State, Nigeria over a 10-year period from 2012 to 2021. Data were collated using a pro forma. Numerical data were summarized as means, median, and standard deviation, whereas categorical data were summarized as frequencies. Statistical significance was pegged at P < 0.05. RESULTS Seventy-three patients were analysed. The mean age of the patients was 71.48 ± 8.15 years. The three most common presenting complaints were lower urinary tract symptoms (LUTSs) 23 (31.5%), acute urinary retention 9 (12.3%), and LUTS with low back pain 9 (12.3%). The median duration of symptoms was 6.5 months. No difference was noted among educational level, occupation, and stage of CaP, (P=0.222 and P=0.548), respectively. The median total prostate-specific antigen was 85.0 ng/mL. Sixty-seven patients (91.8%) had an abdominopelvic ultrasound scan. Fifty patients (68.5%) had stage 4 disease. Thirty-eight (52.1%) had financial constraints. Forty-nine (67.1%) patients were lost to follow-up. Bilateral orchidectomy was offered to 28 (38.4%) patients. CONCLUSION Financial constraint was a huge barrier in the management of CaP patients in this study. Late presentation was common in this study.

Abstract
Objective This study aims to prepare candidate vaccines for cervical cancer immunotherapy by inserting the fused genes of human papillomavirus (HPV)16/18/58 mE6E7 lacking transforming activity into an adenovirus vector and to verify its efficiency in model mice with tumor expressing the associated HPV genes. Methods The E6/E7 genes of HPV16/18/58 were point-mutated to abolish their transforming activity, and adenovirus (AD)-HPV16/18/58 mE6E7 adenovirus vaccine was constructed. The immune effect of the adenovirus vaccine against HPV16/18/58-type tumors was analyzed by tumor morphology, enzyme linked immunosorbent assay, enzyme-linked immunospot and specific cytotoxic T lymphocyte (CTL) and T lymphocyte subsets. Results The HPV16/18/58 mE6E7 plasmid containing point mutations was verified by quantitative real-time polymerase chain reaction (qRT-PCR), enzyme digestion and electrophoresis, and gene sequencing. qRT-PCR and Western blots verified that AD-HPV16/18/58 mE6E7 could express the HPV16 mE6E7, HPV18 mE6E7 and HPV58 mE6E7 fusion genes and proteins in cells. The results of animal experiments were as follows: In the vaccine group, the tumors formed later, the incubation period was longer, the growth was slower, growth was inhibited, and the survival period was significantly prolonged. The immunological results all showed that the vaccine could induce effective humoral and cellular immunity in mice with three types of tumors, compared with the phosphate buffered saline (PBS) group and the adenovirus-negative control (AD-NC) group, the differences were statistically significant (P < 0.05). Conclusion We successfully constructed the HPV16/18/58 trivalent therapeutic adenovirus vaccine AD-HPV16/18/58 mE6E7. The AD-HPV16/18/58 mE6E7 adenovirus vaccine can protect immunized mice to a certain extent from TC-1, U14/LV-HPV18 E6E7 and U14/LV-HPV58 E6E7 cells, which contain HPV16, 18 and 58 E6 and/or E7 genes, respectively.

[PMID: 30061920 PMCID: PMC6056927 DOI: 10.1186/s13027-018-0199-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 07/13/2018] [Indexed: 12/16/2022] Open
Abstract
Background High risk human papillomaviruses (HPVs) have been unequivocally recognised as the necessary cause of squamous intraepithelial lesions (SIL) and invasive carcinoma of the cervix. The distribution and the role of unclassified risk HPV genotypes in cervical neoplasia has not been fully elucidated. Methods Liquid-based cytological samples were collected from 337 women referred for colposcopy following an abnormal cytological diagnosis. HPV DNA was detected by broad-spectrum PCR and genotypes identified by nucleotide sequencing analysis and reverse line blot (RLB). Results The overall frequency of HPV infection was 36.5% (35 out of 96) in samples negative for intraepithelial lesions or malignancy (NILM), 80% (181 out of 226) in low grade SIL and 93.3% (14 out of 15) in high grade SIL (P < 0.001). Thirty-five different genotypes were identified among the 230 HPV-positive cases. The Group 1 oncogenic viruses (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59) were found in 21.9, 46.5, and 86.7% of NILM, low grade SIL and high grade SIL, respectively. The Group 2A, including the probably oncogenic virus HPV68, was found in 1 and 0.8% of NILM and low grade SIL, respectively. The Group 2b possibly oncogenic HPVs (HPV34, 53, 66, 67, 70, 73, 82 and 85) were found in 4.2, 21.7 and 26.7% of NILM, low grade SIL and high grade SIL, respectively. The unclassified viruses (HPV12, 42, 54, 55, 61, 62, 81, 83, 84, 89, 90, 91) were detected in 8.3 and 14.6% of NILM and low grade SIL, respectively, and never in high grade SIL. Conclusions Group 1 HPVs were mainly prevalent in high grade SIL and low grade SIL while Group 2B were equally distributed among the two groups. The dominant frequency of unclassified HPVs in low grade SIL and NILM and their rarity in high grade SIL suggests their marginal role in cervical neoplasia of the studied population.

Abstract
The identification of some types of human papillomavirus (HPV) as necessary, but not sufficient, cause of cervical cancer has suggested the use of HPV testing in cervical cancer prevention. A large number of studies has provided evidence supporting its application (1) as primary screening test, (2) for triaging borderline cytology, (3) for follow-up after positive primary test but no abnormal histology and (4) as a test of cure. They also allowed a reasonably good definition of the appropriate policies and protocols, leading to the delivery of evidence-based guidelines resulting from a systematic review of the literature. In this chapter, we present a critical analysis of the recommendations of the main European and North American guidelines relative to industrialised countries.

Screening women for cervical cancer carcinoma with a HPV mRNA test: first results from the Venice pilot program. Br J Cancer 2016; 115:525-32. [PMID: 27490801 PMCID: PMC4997543 DOI: 10.1038/bjc.2016.216] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2016] [Revised: 05/24/2016] [Accepted: 06/26/2016] [Indexed: 12/02/2022] Open
Abstract
Background: HPV DNA-based screening is more effective than a Pap test in preventing cervical cancer, but the test is less specific. New HPV tests have been proposed for primary screening. The HPV mRNA test showed a similar or slightly lower sensitivity than the HPV DNA tests but with a higher specificity. We report the results of an organised HPV mRNA-based screening pilot program in Venice, Italy. Methods: From October 2011 to May 2014, women aged 25–64 years were invited to undergo a HPV mRNA test (Aptima). Those testing positive underwent cytological triage. Women with positive cytology were referred to colposcopy, whereas those with negative cytology were referred to repeat the HPV mRNA test 1 year later. The results of the HPV mRNA test program were compared with both the local historical cytology-based program and with four neighbouring DNA HPV-based pilot projects. Results: Overall, 23 211 women underwent a HPV mRNA test. The age-standardised positivity rate was 7.0%, higher than in HPV DNA programs (6.8% relative rate (RR) 1.11, 95% confidence interval (CI) 1.05–1.17). The total colposcopy referral was 5.1%, double than with cytology (2.6% RR 2.02, 95% CI 1.82–2.25) but similar to the HPV DNA programs (4.8% RR 1.02; 95% CI 0.96–1.08). The cervical intraepithelial neoplasia grade 2+ detection rate with HPV mRNA was greater than in the HPV DNA programs at baseline (RR 1.50; 95% CI 1.19–1.88) and not significantly lower at the 1-year repeat (RR 0.70; 95% CI 0.40–1.16). The overall RR was 1.29 (95% CI 1.05–1.59), which was much higher than with cytology (detection rate 5.5‰ vs 2.1‰ RR 2.50, 95% CI 1.76–3.62). Conclusions: A screening programme based on the HPV mRNA obtained results similar to those observed with the HPV DNA test. In routine screening programmes, even a limited increase in HPV prevalence may conceal the advantage represented by the higher specificity of HPV mRNA.

Evaluation of careHPV, Cervista Human Papillomavirus, and Hybrid Capture 2 Methods in Diagnosing Cervical Intraepithelial Neoplasia Grade 2+ in Xinjiang Uyghur Women. Oncologist 2016; 21:825-31. [PMID: 27317575 DOI: 10.1634/theoncologist.2015-0447] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2015] [Accepted: 01/29/2016] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE The study aimed to evaluate the value of the Cervista human papillomavirus (HPV), Hybrid Capture 2 (HC-2), and careHPV tests in diagnosing cervical intraepithelial neoplasia grade 2 (CIN2) or worse in Xinjiang Uyghur women. METHODS Three high-risk human papillomavirus (HR-HPV) detection methods were studied on two different populations by different combination modes; a cytology specimen was obtained at the same time. An abnormal result of any test resulted in referral to colposcopy. Cervical biopsy was also performed. RESULTS In population 1, HR-HPV-positive rates were 57.6% and 54.3% as detected by HC-2 and Cervista, respectively; κ = 0.892 for consistency check of HC-2 and Cervista (p < .001). Area under the receiver operating characteristic curve (AUC) of HC-2 and Cervista was 0.744 (95% confidence interval [CI]: 0.664∼0.824, p < .001) and 0.786 (95% CI: 0.715∼0.858, p < .001), respectively, for diagnosing CIN2+. The A9 probe can detect six subtypes of HPV, including HPV16, HPV31, HPV33, HPV35, HPV52, and HPV58. If one or more of these subtypes are postitive, then A9 will be positive. A diagnosis of class A9 by the Cerevista test correlated with pathological interpretations (chi-square = 43.063, p < .001). In population 2, HR-HPV-positive rates were 40.1% and 34.4%, respectively, by HC-2 and careHPV; κ value was 0.779 for the two tests (p < .001). AUC of HC-2 was 0.895 (95% CI: 0.849∼0.940, p < .001), and careHPV was 0.841 (95% CI: 0.770∼0.899, p < .001) for diagnosing CIN2+. CONCLUSION Good consistency was shown between HC-2 and Cervista tests and also between the HC-2 and careHPV tests. In the detection of CIN2+, Cervista showed better specificity than HC-2, and interpretation of the A9 subgroup showed high predicted value. The HC-2 test demonstrated better sensitivity than careHPV in detection of CIN2+. HC-2, Cervista, and careHPV may be applied as a triage test for visual inspection with acetic acid/Lugol's iodine-positive or ThinPrep cytologic test-positive women. The careHPV test was comparatively economical and efficient and may be more suitable for resource-limited regions, such as Xinjiang. IMPLICATIONS FOR PRACTICE This study was designed to evaluate the value of the Cervista human papillomavirus (HPV), Hybrid Capture 2 (HC-2), and careHPV tests in diagnosing cervical intraepithelial neoplasia grade 2 (CIN2) or worse (CIN2+) lesions in Xinjiang Uyghur women. Results showed that there was good consistency between the HC-2 and Cervista tests, as well as between the HC-2 and careHPV tests. In detecting CIN2+, Cervista had higher specificity than HC-2, whereas analysis of the A9 subgroup had high predictive value. (The A9 probe can detect six subtypes of HPV, including HPV16, HPV31, HPV33, HPV35, HPV52, and HPV58. If one or more of these subtypes are postitive, then A9 will be positive.) The HC-2 test demonstrated better sensitivity than careHPV in detecting CIN2+. HC-2, Cervista, and careHPV could be applied as a triage test for visual inspection with acetic acid/Lugol's iodine-positive or ThinPrep cytologic test-positive women. The careHPV test was comparatively economical and efficient and may be more suitable for resource-limited regions, such as Xinjiang.

Abstract
Human papillomavirus (HPV) and Chlamydia trachomatis are pathogens with oncogenic potential associated with persistent infections. Epidemiological data on C. trachomatis infection status, C. trachomatis/HPV co-infection and the relationship between HPV genotypes in Italian women are only preliminary. The aim of the present study was to characterize the relationship between HPV genotypes and C. trachomatis in an extending cohort of asymptomatic immunocompetent women from an area of north-east Italy. A retrospective study was conducted using Luminex technology on cervical swabs from asymptomatic immunocompetent women, comprising 921 attending the prevention centre for the Cervical Cancer Program and 6214 who had been referred to the Sexually Transmitted Infections Center, with clinical indications of HPV and C. trachomatis infections. A quantitative real-time PCR was performed to assess chronic C. trachomatis infection by heat-shock protein 60 (Hsp60) gene expression. The overall prevalence of the investigated pathogens was 39 % (359/921) for HPV and 4 % (251/6214) for C. trachomatis. The Hsp60 gene was detected in 57 % of the women infected with C. trachomatis. HPV co-infection was present in 58 % of C. trachomatis-infected women. A high prevalence of co-infection was found in women with chronic C. trachomatis infection (68 %, P = 0.0002), especially in women ≤ 25 years (72 %) where HPV multiple infections were found in 78 % (P = 0.022). HPV genotype distribution showed that uncommon low-risk genotypes were associated with C. trachomatis. These results indicate a high frequency of co-detection of multiple HPV genotypes in chronically infected young women and suggest that the expression of the C. trachomatis Hsp60 gene may favour HPV infection.

Abstract
Schiff-based complexes as a source of cancer chemotherapeutic compounds have been subjected to the variety of anticancer studies. The in-vitro analysis confirmed the CdCl2(C14H21N3O2) complex possess cytotoxicity and apoptosis induction properties in colon cancer cells, so lead to investigate the inhibitory efficiency of the compound on colonic aberrant crypt foci (ACF). Five groups of adult male rats were used in this study: Vehicle, cancer control, positive control groups and the groups treated with 25 and 50 mg/kg of complex for 10 weeks. The rats in vehicle group were injected subcutaneously with 15 mg/kg of sterile normal saline once a week for 2 weeks and orally administered with 5% Tween-20 (5 ml/kg) for 10 weeks, other groups were injected subcutaneously with 15 mg/kg azoxymethane once a week for 2 weeks. The rats in positive groups were injected intra-peritoneally with 35 mg/kg 5-Flourouracil four times in a month. Administration of the complex suppressed total colonic ACF formation up to 73.4% (P < 0.05). The results also showed that treatment with the complex significantly reduced the level of malondialdehyde while increasing superoxide dismutase and catalase activities. Furthermore, the down-regulation of PCNA and Bcl2 and the up-regulation of Bax was confirmed by immunohistochemical staining.

Abstract
BACKGROUND Human Papillomavirus (HPV) genotyping is an important approach to fight cervical cancer due to the relevant information regarding risk stratification for diagnosis and the better understanding of the relationship of HPV with carcinogenesis. This paper proposed two new feature extraction techniques, i.e. ChaosCentroid and ChaosFrequency, for predicting HPV genotypes associated with the cancer. The additional diversified 12 HPV genotypes, i.e. types 6, 11, 16, 18, 31, 33, 35, 45, 52, 53, 58, and 66, were studied in this paper. In our proposed techniques, a partitioned Chaos Game Representation (CGR) is deployed to represent HPV genomes. ChaosCentroid captures the structure of sequences in terms of centroid of each sub-region with Euclidean distances among the centroids and the center of CGR as the relations of all sub-regions. ChaosFrequency extracts the statistical distribution of mono-, di-, or higher order nucleotides along HPV genomes and forms a matrix of frequency of dots in each sub-region. For performance evaluation, four different types of classifiers, i.e. Multi-layer Perceptron, Radial Basis Function, K-Nearest Neighbor, and Fuzzy K-Nearest Neighbor Techniques were deployed, and our best results from each classifier were compared with the NCBI genotyping tool. RESULTS The experimental results obtained by four different classifiers are in the same trend. ChaosCentroid gave considerably higher performance than ChaosFrequency when the input length is one but it was moderately lower than ChaosFrequency when the input length is two. Both proposed techniques yielded almost or exactly the best performance when the input length is more than three. But there is no significance between our proposed techniques and the comparative alignment method. CONCLUSIONS Our proposed alignment-free and scale-independent method can successfully transform HPV genomes with 7,000 - 10,000 base pairs into features of 1 - 11 dimensions. This signifies that our ChaosCentroid and ChaosFrequency can be served as the effective feature extraction techniques for predicting the HPV genotypes.

Abstract
BACKGROUND Chlamydia trachomatis interaction with HR-HPV types has highlighted a central role in cervical cancer development. The aim of this study was to investigate HPV prevalence and genotypes distribution in women at risk for C. trachomatis infection and negative for intraepithelial lesion or malignancy. METHODS 1071 cervical swabs were tested for C. trachomatis by Real Time PCR and genotyping by ompA gene sequencing. Additionally, a quantitative Real time-PCR was performed to assess the expression of the C. trachomatis Hsp60-encoding gene (Ct604 portion), linked to a persistent status of infection. HPV infection and genotypes was investigated in C. trachomatis positive women using Luminex technology. RESULTS C. trachomatis infection was detected in 53 out of 1071 (4.5%) samples, of which the 53% resulted positive for Hsp60 gene expression. The overall prevalence of HPV infection in C. trachomatis positive samples was of 60.4% (32/53): in 37.5% of samples was present a single genotype, while multiple genotypes infections were found in the 62.5% of them. Among women with a C. trachomatis chronic infection, 68% were HPV co-infected and the 79% showed multiple genotypes. Should be noted that levels of C. trachomatis Hsp60 expression in HPV co-infected women were significantly lower compared to women infected only with C. trachomatis. The C. trachomatis serotype F was found in the majority of samples, independently of HPV infection. CONCLUSIONS A high prevalence of HPV multiple infections have been found in young women affected with a C. trachomatis chronic infection. These observations suggested that the expression of CHSP60-1, interfering with both apoptotic and cellular senescence pathways, may promote a favourable local microenvironment for HPV infection.

Abstract
CONTEXT AND OBJECTIVE The concept that the presence of atypical squamous cells cannot exclude high-grade squamous intraepithelial lesions (ASC-H) was introduced in the 2001 Bethesda System of cervical cytology classification. This nomenclature defines cervical cancer precursor lesions. The objective of this study was to investigate the colpocytological-histological results from a three-year follow-up conducted on a cohort of women with reports of ASC-H who were attended during 2005-2006 at clinics of the Southern Metropolitan Healthcare Service of Santiago, Chile. DESIGN AND SETTING Prospective cohort study at primary healthcare clinics in Santiago, Chile. METHODS Colpocytological-histological follow-up was conducted over a three-year period on 92 women with cytological reports of ASC-H who were attended at primary healthcare clinics during 2005-2006. RESULTS At the end of the follow-up period, high-grade lesions were evaluated and the following outcomes were observed: seven women presented invasive cancer (7.6%), 49 presented high-grade lesions (53.3%), 26 presented low-grade lesions (28.2%) and 10 presented normal results (10.9%). The "Conditional Probabilities Tree Diagram" was used to show the results from tests and the times of lesion detection. It demonstrated that, after a first report of ASC-H, clinical management needed to be interventionist. CONCLUSION The follow-up on our cohort of women showed that the majority of uncertain ASC-H diagnoses (82.6%) had abnormal colposcopic results and that during the follow-up using ASC-H smears, two out of every three women developed high-grade lesions.

Abstract
The aim of this study was to assess the prevalence of HPV infection and determinants of abnormal cytology in HIV-positive patients.
In a cross-sectional study, patients of both sexes, asymptomatic for HPV, underwent anorectal (men)/cervical (women) and oral swabs. Cytology and HPV-PCR detection/genotyping (high- and low-risk genotypes, HR-LR/HPV) were performed. A total of 20% of the 277 enrolled patients showed oral HPV, with no atypical cytology; in men, anal HPV prevalence was 81% with 64% HR genotypes. In women, cervical HPV prevalence was 58% with 37% HR-HPV. The most frequent genotypes were HPV-16 and HPV-18; 37% of men and 20% of women harbored multiple genotypes. Also, 47% of men showed anal squamous intraepithelial lesions (SILs); 6% had high- and 35% low-grade SILs (HSILs/LSILs); 5% had atypical squamous cells of undetermined significance (ASC-US). HR-HPV was independently associated with anal-SIL in men (P = 0.039). Moreover, 37% of women showed cervical SIL: 14 ASC-US, 15 LSILs, 4 HSILs, and 1 in situ cancer. The presence of both LR and HR-HPV in women was independently associated with SIL (P = 0.003 and P = 0.0001). HR-HPV and atypical cytology were frequently identified in our cohort. HPV screening should be mandatory in HIV-infected subjects, and vaccine programs for HPV-negative patients should be implemented.

A cross-sectional study to estimate high-risk human papillomavirus prevalence and type distribution in Italian women aged 18-26 years. BMC Infect Dis 2013; 13:74. [PMID: 23390953 PMCID: PMC3599585 DOI: 10.1186/1471-2334-13-74] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2012] [Accepted: 01/29/2013] [Indexed: 12/22/2022] Open
Abstract
Background Pre-vaccination information on HPV type-specific prevalence in target populations is essential for designing and monitoring immunization strategies for cervical cancer (CC) prevention. Data on HPV prevalence in Italy are available for women over the age of 24 years, target of the population-based CC screening programmes; while data of HPV prevalence in younger ages are very limited. The present study enrolled Italian women aged 18–26 years in order to assess the prevalence and distribution of high-risk (HR) HPV types. Risk-factors correlated with HR-HPV positivity were also described. Methods A sample of 2,289 women was randomly selected from the resident population lists of ten Local Health Units (LHUs) located in six Italian Regions scattered across the country; both rural and urban LHUs were involved. Women aged between 18 and 26 years and living in the selected LHUs were included in the study; pregnant women and women who did not speak Italian were excluded. A total of 1,102 women met the inclusion criteria and agreed to participate. Participants were offered pap test and Hybrid-Capture 2 (HC2) test for HR-HPV types and genotyping was performed on positive smears. Results Out of 1,094 valid samples, 205 (18.7%) were HR-HPV positive. Women with 2–4 (ORadj = 4.15, 95%CI: 2.56-6.72) and ≥5 lifetime partners (ORadj = 10.63, 95%CI: 6.16-18.36) and women who have used any contraceptive in the last six months (ORadj = 1.67, 95%CI: 1.09-2.54) had a higher risk to be infected; women living with their partner had a lower risk (ORadj = 0.56, 95%CI: 0.34-0.92) to acquire infection than women living with parents/friends/alone. Among HC2 positive women, HPV16 was the most prevalent type (30.9%), followed by 31 (19.6%), 66 (12.9%), 51 (11.3%), 18 (8.8%), 56 (8.8%). Co-infections of HR-HC2 targeted types were found in 20.4% of positive samples. The HR-HPV prevalence in women with abnormal cytology (52.4%) was significantly higher than in women with normal cytology (14.6%); however 33.0% of HR-HPV infected women had an abnormal cytology. Conclusion HR-HPV prevalence in Italian women aged 18–26 years was 19%, higher than what detected for older women, by other studies using the same molecular method and laboratory network; this result supports the choice of electing girls before the sexual debut as the primary target of HPV vaccination. The HPV type distribution found in this study may represent a baseline picture; an accurate post-vaccine surveillance is necessary to early detect a possible genotype replacement. The high prevalence of viral types other than vaccine-HPV types supports the necessity to guarantee the progression of CC screening programmes in vaccinated women.

Abstract
BACKGROUND Wolfsburg HPV Epidemiological Study (WOLVES) is a population-based cohort study on HPV infections and associated diseases in the pre-vaccination era in young women in Wolfsburg, Germany. METHODS Women born 1983/84 or 1988/89 were invited to participate. Participants were recruited in gynecology practices, and completed a questionnaire with socioeconomic, sexual and medical data including vaccination status. Pelvic examination with Pap smear and HPV testing (HC2 = Hybrid Capture 2) was obligatory. HC2-positive and 10% of HC2-negative samples were tested for specific HPV types with SPF-10-PCR, and in inconclusive cases with DNA sequencing. Women with genital warts (GW) and those with atypical Pap smears were transferred for colposcopy. GWs were classified as typical condylomata acuminata (TCA), flat condyloma (FC) and seborrheic wart-like (SWL). RESULTS In total, 1258 subjects were recruited from the target population of 2850 (44.1%). Overall the prevalence of HC2 low-risk (LR) types was 8.5%. HPV6 was the most frequent LR type (2.1%), followed by HPV42 (1.1%), HPV11 and HPV44 (each 0.4%). LiPA showed a low sensitivity for HPV types 42, 90 and 91, which were detected only by HC2 and HPV sequencing. Nine women (0.7%) were transferred with incident GW: five TCA, two FC and two SWL. All TCA were associated with HPV6 in corresponding cervical swabs and warts. Tissues of SWL contained HPV6 (n = 1) and HPV16 (n = 1). The cumulative life-risk for GW was 1.4% in the 1988/89 and 4.8% in the 1983/84 cohort. Eight of 107 HC2-LR + and five of nine cases of GW had concomitant abnormal Pap smears. All CIN lesions could be linked to high-risk HPV types but borderline and low-grade abnormal smears were explained by vaginal and cervical TCA in four cases. CONCLUSIONS HC2 was a specific test for the detection of established and potential LR types. In this first WOLVES analysis, HPV6 was the most frequent HPV type and the single LR type linked to disease. The observed GW incidence of 715 per 100,000 fits well with estimates of healthcare providers. Although life risks for GW were lower than in Scandinavian analyses, the societal burden within the WOLVES populations was considerable.

Abstract
This study compares colposcopy referrals of 2 management strategies: oncogenic human papillomavirus (HPV)-DNA testing (Hybrid Capture 2 assay, Qiagen, Germantown, MD) and repeat cytology. In the New Technology in Cervical Cancer Trial, 22,708 subjects were randomly assigned to undergo both HPV and liquid-based cytologic testing. Women aged 35 to 60 years old with unsatisfactory cytologic findings were directly referred for colposcopy if the HPV test result was positive, and were referred for repeat cytologic examination if the HPV test result was negative; women aged 25 to 35 years old were referred for repeat cytologic examination independent of HPV test results. A positive or a second unsatisfactory cytologic examination referred women for colposcopy. Five hundred sixty women had unsatisfactory cytologic findings. Colposcopy referral was not significant and slightly higher with HPV testing than repeat cytologic test (9.8% vs 6.8%, P = .11). When cytologic testing was repeated 36.8% were unavailable for follow-up and most of the colposcopies were performed in HPV-negative women. For unsatisfactory cytologic findings, HPV triage is a more logical and efficient management strategy than a repeat cytologic test.
