Abstract
INTRODUCTION The implication of arginase enzyme in Human Papillomavirus (HPV) infections has not been clearly elucidated. The present study investigates whether HPV infection is correlated with changes in plasmatic arginase activity and cervical ARG1 and ARG2 mRNA expression among infected women negative for intraepithelial lesions (NIL). MATERIEL AND METHODS The present study included 300 women. The plasmatic arginase activity was evaluated by a colorimetric assay. Cervical HPV was detected by real-time PCR. The circulating viral load and ARG1 and ARG2 mRNA expression quantification were performed by quantitative real-time PCR. RESULTS A significant increase in plasma arginase activity and ARG1 and ARG2 mRNA expression levels in cervical cells was observed among HPV-positive women compared to the HPV-negative group. The highest levels were significantly associated with oncogenic HPV, and increased arginase activity was associated with a high HPV circulating viral load. Moreover, the highest levels of arginase activity were observed in oncogenic HPV-positive inflammatory smears. DISCUSSION These data suggest that HPV could modulate arginase activity and expression, which may restrict arginine bioavailability and inhibit this amino acid's antiviral properties. CONCLUSION Our findings revealed that arginase activity and isoform gene expression were upregulated in women with HPV infection, particularly the oncogenic HPV types.

The Prevalence, Genotype Distribution and Risk Factors of Human Papillomavirus in Tunisia: A National-Based Study. Viruses 2022; 14:v14102175. [PMID: 36298732 PMCID: PMC9611589 DOI: 10.3390/v14102175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/21/2022] [Accepted: 09/29/2022] [Indexed: 11/28/2022] Open
Abstract
There are limited national population-based studies on HPV genotypes distribution in Tunisia, thus making difficult an assessment of the burden of vaccine-preventable cervical cancer. In this context, we conducted a national survey to determine the HPV prevalence and genotypes distribution and the risk factors for HPV infections in Tunisian women. This is a cross-sectional study performed between December 2012 and December 2014. A liquid-based Pap smear sample was obtained from all women and samples' DNAs were extracted. Only women with betaglobin-positive PCR were further analysed for HPV detection and typing by a nested-PCR of the L1 region followed by next-generation sequencing. A multiple logistic regression model was used for the analysis of associations between the variables. A total of 1517 women were enrolled in this study, and 1229 out of the 1517 cervical samples were positive for the betaglobin control PCR and tested for HPV. Overall HPV infection prevalence was measured to be 7.8% (96/1229), with significant differences between the grand regions, ranging from 2% in the North to 13.1% in Grand Tunis. High-risk HPV genotypes accounted for 5% of the infections. The most prevalent genotypes were HPV 31 (1%), 16 (0.9%), 59 (0.7%). HPV18 was detected only in four cases of the study population. Potential risk factors were living in Grand Tunis region (OR: 7.94 [2.74-22.99]), married status (OR: 2.74 [1.23-6.13]), smoking habit (OR: 2.73 [1.35-5.51]), occupation (OR: 1.81 [1.09-3.01]) and women with multiple sexual partners (OR: 1.91 [1.07-3.39]). These findings underscore the need to evaluate the cost effectiveness of HPV vaccine implementation, contribute to the evidence on the burden of HPV infections, the critical role of sexual behaviour and socioeconomic status, and call for increased support to the preventive program of cervical cancer in Tunisia.

Abstract
Background In the past decade, cervical cancer has gone from being the second to the fourth most common cancer in women worldwide, but remains the second most common in developing countries. This cancer is most commonly caused by high-risk types of human papillomavirus (HPV), mainly type 16 (HPV16), which are sexually transmitted. This study aimed to investigate the usefulness of a cyclic synthetic peptide designed from the major L1 capsid protein of HPV16 for detecting anti-HPV16 antibodies. Methods We designed and synthetized a peptide that corresponds to the full sequence of the surface-exposed FG loop. We tested the antigenicity of the linear and the cyclic peptides against HPV16 L1 monoclonal antibodies. We used ELISA to detect anti-peptide antibodies in sera and cervical secretions of 179 Tunisian women, and we applied polymerase chain reaction and direct sequencing methods to detect and genotype HPV DNA. Results Both the linear and the cyclic peptides were recognized by the same neutralizing monoclonal antibodies, but the cyclic peptide was more reactive with human sera. The prevalence of the anti-peptide antibodies in sera was higher in women with low-grade squamous intraepithelial lesions (LGSIL) than in women with high-grade squamous intraepithelial lesions (HGSIL) (44% and 15%, respectively). This contrasts with HPV16 DNA prevalence. Compared to women from the general population, systemic IgG prevalence was significantly higher among sex workers (25%; P = 0.002) and women with LGSIL (44%; P = 0.001). In addition, systemic IgA and cervical IgG prevalence was higher among sex workers only (P = 0.002 and P = 0.001, respectively). We did not observe anti-peptide IgG antibodies in women with a current HPV16 infection. Conclusion Anti-peptide IgG in sera or in cervical secretions could be markers of an effective natural immunization against HPV16. This may open novel perspectives for monitoring vaccinated women and for the design of synthetic peptide-based vaccines.

HIV epidemiology among female sex workers and their clients in the Middle East and North Africa: systematic review, meta-analyses, and meta-regressions. BMC Med 2019; 17:119. [PMID: 31230594 PMCID: PMC6589882 DOI: 10.1186/s12916-019-1349-y] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Accepted: 05/22/2019] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND HIV epidemiology among female sex workers (FSWs) and their clients in the Middle East and North Africa (MENA) region is poorly understood. We addressed this gap through a comprehensive epidemiological assessment. METHODS A systematic review of population size estimation and HIV prevalence studies was conducted and reported following PRISMA guidelines. Risk of bias (ROB) assessments were conducted for all included studies using various quality domains, as informed by Cochrane Collaboration guidelines. The pooled mean HIV prevalence was estimated using random-effects meta-analyses. Sources of heterogeneity and temporal trends were identified through meta-regressions. RESULTS We identified 270 size estimation studies in FSWs and 42 in clients, and 485 HIV prevalence studies in 287,719 FSWs and 69 in 29,531 clients/proxy populations. Most studies had low ROB in multiple quality domains. The median proportion of reproductive-age women reporting current/recent sex work was 0.6% (range = 0.2-2.4%) and of men reporting currently/recently buying sex was 5.7% (range = 0.3-13.8%). HIV prevalence ranged from 0 to 70% in FSWs (median = 0.1%) and 0-34.6% in clients (median = 0.4%). The regional pooled mean HIV prevalence was 1.4% (95% CI = 1.1-1.8%) in FSWs and 0.4% (95% CI = 0.1-0.7%) in clients. Country-specific pooled prevalence was < 1% in most countries, 1-5% in North Africa and Somalia, 17.3% in South Sudan, and 17.9% in Djibouti. Meta-regressions identified strong subregional variations in prevalence. Compared to Eastern MENA, the adjusted odds ratios (AORs) ranged from 0.2 (95% CI = 0.1-0.4) in the Fertile Crescent to 45.4 (95% CI = 24.7-83.7) in the Horn of Africa. There was strong evidence for increasing prevalence post-2003; the odds increased by 15% per year (AOR = 1.15, 95% CI = 1.09-1.21). There was also a large variability in sexual and injecting risk behaviors among FSWs within and across countries. Levels of HIV testing among FSWs were generally low. The median fraction of FSWs that tested for HIV in the past 12 months was 12.1% (range = 0.9-38.0%). CONCLUSIONS HIV epidemics among FSWs are emerging in MENA, and some have reached stable endemic levels, although still some countries have limited epidemic dynamics. The epidemic has been growing for over a decade, with strong regionalization and heterogeneity. HIV testing levels were far below the service coverage target of "UNAIDS 2016-2021 Strategy."

Cervical Human Papillomavirus Prevalence, Genotypes, and Associated Risk Factors among Female Sex Workers in Greater Accra, Ghana. JOURNAL OF ONCOLOGY 2019; 2019:8062176. [PMID: 31275383 PMCID: PMC6582788 DOI: 10.1155/2019/8062176] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Accepted: 05/14/2019] [Indexed: 11/29/2022]
Abstract
Cervical cancer is a largely preventable disease mediated by persistent infection with high-risk Human Papillomaviruses (Hr-HPV). There are now three approved vaccines against the most common HPV genotypes. In Ghana, mortality due to cervical cancer is on the rise, due to the absence of an organized and effective cervical cancer prevention and control program. Data on circulating HPV genotypes is important for studying the likely impact of mass introduction of HPV vaccination of the female population before sexual debut. High HPV prevalence has been reported in Female Sex Workers (FSWs), who constitute an important active group for maintenance of HPV in the population. This study was conducted to determine the size of HPV prevalence in this group and to provide information for future assessment of the impact of vaccine introduction in the country. We conducted a cross-sectional study where the snowballing technique was used to identify and select FSW's ≥18 years, operating within suburbs of Greater Accra Region (GAR). A risk factor assessment interview was conducted and cervical swabs were collected for HPV-DNA detection and genotyping by Nested Multiplex PCR. Hundred participants, age ranging from 18 to 45 years, median 24 years, were studied. The prevalence of Cervical HPV was 26%. Eleven genotypes were detected comprising 9 high-risk in order of decreasing prevalence HPV-16 (8%), HPV-35 (5%), HPV-33/39/-68 (3%), HPV-52/51/59 (2%) and HPV-18 (1%) and 2 Low-risk types, HPV-42(3%), and HPV-43 (1%). Three women had HPV types that could not be genotyped by our method. Oral contraceptives use was associated with a reduced chance of HPV infection (P=0.002; OR=0.19, 95% CI 0.07-0.54). This study found a high HPV prevalence among FSWs in the GAR. A high number of Hr-HPV genotypes seen are vaccine preventable, providing additional compelling argument for implementing a national cervical cancer prevention plan including vaccination.

Abstract
Background: High-risk human papillomavirus (HPV) types are the main etiological factors for cervical cancer. HPV16 and HPV18 are generally the most common forms associated with development of high-grade cervical lesions. This study was undertaken to identify intratypic variants of HPV16 and HPV18 among women with cervical lesions in Tunisia. Materials and Methods: DNA was extracted from cervical samples collected from 49 women. using a PureLinkTM Genomic DNA mini Kit (Invitrogen). E6 and L1 open reading frames (ORF) were amplified by PCR and viral DNA amplicons were subjected to automated sequencing using Big Dye Terminators technology (Applied Biosystems). The obtained sequences were analyzed using an appropriate software program to allow phylogenetic trees to be generated. Results: HPV16 and HPV18 were detected in 15 and 5 cases, respectively. HPV16 E6 sequences clustered with the European German lineage (A2) whereas one isolate diverged differently in the L1 region and clustered with the African sub-lineage (B1). HPV 18 E6 sequences clustered with the European sub-lineage (A1) but L1 sequences clustered as a new clade which diverged from A1-A5. Conclusions: Our results suggest that the distribution of HPV16 and HPV18 sequences in women with cervical lesions in Tunisia is mainly related to European epidemiological conditions and point to the presence of recombinant HPV forms.

Abstract
BACKGROUND Little is known about the epidemiological characteristics of papillomavirus (HPV) infection among North African countries. Herein, we conducted a molecular epidemiological study to investigate prevalence of HPV type and HPV-16 variants among cervical-screened unvaccinated Tunisian women. METHODS Cross-sectional study was performed on 494 Tunisian women visiting Women's Healthcare Centers. HPV-DNA detection was carried out on cervical samples using real-time polymerase chain reaction. HPV genotyping and HPV-16 variants were characterized by direct sequencing of L1 viral capsid gene. RESULTS The overall HPV prevalence was 34% (95% CI: 30-38%) with significantly higher prevalence among women with squamous intraepithelial lesions (SIL) than those with no intraepithelial lesions (NIL) 84% (95% CI: 76-92%) and 24.5% (95% CI: 20-29%) respectively. The distribution of HPV prevalence according to women's age shows a U-shaped curve and the highest HPV prevalence rates were observed among the youngest (≤25 years; 51.2%, 95% CI: 37-67%) and the oldest women (>55 years; 41.7%, 95% The HPV-16 prevalence was 32.8% (95% CI: 22-45%) among women with SIL and 9.2% (95% CI: 6-12%) among women with NIL. Whereas, the HPV-18 prevalence was 1.3% (95% CI: 0-5%) among women with SIL and 0.3% (95% CI: 0-1%) among women with NIL. Among HPV-16 positive women, European lineage (E) was identified as the predominant HPV-16 variant (85.7%, 95% CI: 76-95%). The frequency of E variant was lower among SIL than among NIL women (81%, 95% CI: 64-99%, and 88%, 95% CI: 77-100%, respectively). Conversely, the African-2 variant frequency was higher among SIL than among NIL women (18%, 95% CI: 1-36% and 6%, 95% CI: 2-14%, respectively). In multivariate analysis, young age was the only risk factor that is independently associated with HPV infection. Moreover, HPV infection and menopause were both found to be independently associated with SIL and HSIL. CONCLUSION HPV DNA testing should be proposed to young and menopausal Tunisian women. Considering HPV prevalence, only 13% of the Tunisian women could be protected by the bivalent HPV vaccine. These results may be helpful for designing an adapted HPV testing and vaccination program in Tunisia.

Abstract
OBJECTIVE In many African Sub-Saharan countries, human papilloma virus (HPV) prevalence data are not available. The current study estimated the prevalence of HPV virus in the female population of Djibouti. METHODS Approximately 1000 asymptomatic women 16 to 64 years old were enrolled from 3 of the main health structures of Djibouti in 2014 and 2015; 998 cervical samples were tested for HPV-DNA of high risk types, 499 during the first year, and 499 during the second. Positive samples were typed with an HPV genotyping kit. RESULTS The women were an average age of 38.8 years (SD, 10.2); 54 women tested positive for HPV (prevalence rate, 5.4% [95% confidence interval, 4.0-6.8]). The highest prevalence was observed among the women younger than 35 years. HPV66 was the most prevalent (15.4% of the infections), followed by HPV31 and HPV52 (10.8% both) and HPV16 (9.2%). All 54 women who tested HPV-positive underwent a Pap test, which was positive in 8 cases (14.8%): 2 high-grade squamous intraepithelial lesion (HSIL) and 6 low-grade (LSIL). CONCLUSIONS The HPV prevalence shows a curve by age similar to that of other African countries. The proportion of HPV16 is among the lowest ever seen in similar studies. The findings suggest to Djibouti the choice of a strategy of screening that includes forms of cytological triage, thus limiting recourse to colposcopy.

Abstract
Introduction: Approximately 291 million women worldwide are HPV DNA carriers. Studies have indicated
that having multiple sexual partners may lead to higher HPV transmission. Thus female sex workers (FSWs) may be at
greater risk of infection compared to the general population. Herein we review publications with data on FSW cervical
HPV test results. We also examine variations of HPV prevalence and risk behaviors by region. Knowledge of prevalent
HPV types in FSWs may lead to improved prevention measures and assist in understanding vaccination in high-risk
groups. Methods: We conducted a review of the literature by searching PUBMED using the terms “prostitution” or “female sex
workers”, “human papillomavirus” or “HPV”, and “prevalence” or “PCR” to find articles. We excluded studies without
HPV testing or HPV type specific results, or unconventional HPV testing. Results: A total of 35 peer-reviewed publications were included in our review. High risk HPV types 16 and 18 ranged
from 1.1-38.9‰ in prevalence. In addition to high-risk HPV types, newer studies reported non-carcinogenic HPV types
also of high prevalence. The most prevalent HPV types reported among FSWs included HPV 6 (11.5%), 16 (38.9%), 18
(23.1%), 31 (28.4%), 52 (32.7%), and 58 (26.0%). Conclusions: Female sex workers have an overall high prevalence of HPV infection of high-risk types as evident through
various testing methods. FSWs are thought to be at increased risk of cervical cancer because of high HPV exposure. This
highlights the need for HPV and cervical prevention campaigns tailored to FSWs.

Abstract
Cervical cancer is the second most common cancer among Tunisian women, and the incidence rates vary by region. Three Tunisian registries report age-standardized rates of 6.3/10(5) in the central region, 5.4/10(5) in the north, and 2.7/10(5) in the south. High-risk human papillomavirus (HPV) types and their variants differ in carcinogenic potential and geographic distribution. The HPV type and variant distribution could be a factor in the differing rates between regions of Tunisia. Tumor tissue was collected from 142 Tunisian cervical cancer patients. Demographic and reproductive characteristics of the patients were abstracted from cancer registry and hospital records. HPV type and variant analyses were performed using PCR-based Luminex and dot-blot hybridization assays. Eighty-three percent of tumors were infected with at least one HPV type. European variants of HPV16/18 were the most prevalent in tumors from all three regions, with all HPV18 infections and 64% of HPV16 infections being of European lineage. A higher frequency of HPV16 was present in Northern Tunisia (80%) than in Central (68%) or Southern Tunisia (50%) (P=0.02). HPV18/45 was significantly more common in adenocarcinomas (50%) than in squamous cell carcinomas (11%) (P=0.004). Frequent infection with European HPV variants most likely reflects the history of European migration to Tunisia. In addition to the importance of understanding the variants of HPV in Tunisia, behavioral and cultural attitudes towards screening and age-specific infection rates should be investigated to aid the development of future vaccination and HPV screening programs and policies.

No evidence of human papillomavirus DNA in breast carcinoma in Tunisian patients. Breast 2010; 19:541-4.

Abstract
The aim of this study was to evaluate the prevalence of broad range of anogenital HPVs in a series of 123 Tunisian breast carcinoma cases. PCR assays were performed to amplify regions within the L1, E1, E6 and E7 open reading frames of a broad range of anogenital HPVs and specific types HPV16, 18, 31 and 33. In addition, we performed an in situ hybridization analysis using HPV biotinylated DNA probes for the detection of broad spectrum of anogenital HPV types, high-risk HPV types (16 and 18), intermediate-risk HPV types (31 and 33) and low-risk HPV types (6 and 11). None of the 123 breast carcinoma samples showed PCR amplification of HPV DNA using the broad spectrum consensus primer-pairs E1-350L/E1-547R and GP5+/GP6+ primers. Furthermore, neither high risk nor low-risk HPV types were detected in any of these cases. Moreover, using in situ hybridization for the detection of HPVs, we failed to detect a positive signal in neoplastic cells in any case. Our results suggest that anogenital papillomaviruses are unlikely to play a role in the development of breast carcinomas in Tunisian patients.

Abstract
The aim of this study was to determine human papillomavirus (HPV) types distribution in cervical preneoplasic lesions in a Southern Spanish population and their relationship between HPV type and grade of histopathological abnormality. Finally, 232 cervical samples from 135 women with previous cytological abnormalities were included in this study. Colposcopy studies and biopsies were performed. Haematoxylin-eosin stained slides were observed and detection of HPV DNA in cervical swabs was carried out with use of a polymerase chain reaction and microarrays technology. The relationship between the presence of HPV infection and diagnostic variables was evaluated. HPV 16 was the most common type followed by HPV 58, 51, 33 and 31. However, the two HPV types targeted in the prophylactic vaccines such as HPV type 16 and 18 were detected in only 37 (21.2%) and 2 (1.1%) cases respectively. Thirty-three (18.9%) of samples were infected with multiple types, the majority of them with two types. In addition, during the follow-up of patients many changes in type distribution were observed. Several studies will be necessary in order to evaluate the HPV type distribution for therapeutically and prophylactic purposes such as vaccine treatment. Also, because of the differences obtained depending of use of various DNA technologies, the performance of some comparative studies of the different methods from detection of HPV would be advisable in a high population of patients and with the most homogeneous conditions possible.

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
The aim of the study was to estimate the prevalence and risk factors associated with infection by high-risk human papillomavirus (HR-HPV) in cervix and squamous intra-epithelial lesions (SIL) in imprisoned women. This was done by a cross-sectional study of imprisoned women attending the gynaecological clinic in Foncalent prison in Alicante, Spain. The study period was from May 2003 to December 2005. HR-HPV infection was determined through Digene HPV Test, Hybrid Capture II (HC-II). HPV typing was determined by multiplex nested PCR assay combining degenerate E6/E7 consensus primers. Multiple logistic regression modelling was used for the analysis of associations between variables where some were considered possible confounders after checking for interactions. A total of 219 women were studied. HR-HPV prevalence was 27.4% and prevalence of SIL was 13.3%. HIV prevalence was 18%, higher in Spaniards than in migrant women (24.6% vs. 14.3%, P<0.05). In multivariate analyses, risk factors for HPV infection were younger age (P for trend=0.001) and tobacco use (OR 2.62, 95% CI 1.01-6.73). HPV infection (OR 4.8, 95% CI 1.7-13.8) and HIV infection were associated with SIL (OR 4.8, 95% CI 1.6-14.1). The commonest HPV types were HPV16 (29.4%), HPV18 (17.6%), HPV39 (17.6%) and HPV68 (17.6%). The prevalence of both HR-HPV infection and SIL in imprisoned women found in this study is high. Determinants for each of the outcomes studied were different. HPV infection is the most important determinant for SIL. A strong effect of HIV co-infection on the prevalence of SIL has been detected. Our findings reinforce the need to support gynaecological clinics in the prison setting.

Abstract
The prevalence of single and multiple HPV infections was assessed over a cohort of 213 women with cytological abnormalities and its association with cervical neoplasia established. Roche linear array HPV genotyping test was used to identify HPV genotypes. The most prevalent HPV genotypes in cervical cancer samples were HPV16 (61.2%), HPV52 (16.1%), HPV18 (12.9%) and HPV 31 (9.6%). Multiple HR and LR HPV infections, comprising between two and 5+ HPV types, were identified in 49.7% of samples, with a significantly lower number in severe dysplasia and cervical cancer samples (p<0.05). These results seem to indicate that detection of multiple HPV infection with HR-HPV types is not significantly better as a predictor of cervical cancer than single HR-HPV infection, though further longitudinal studies are needed to better clarify the relevance of these infections to the progression of cervical neoplasia.

Abstract
BACKGROUND We attempted to determine the prevalence of genital human papillomavirus (HPV) infection in women attending gynecologic practitioners in South Taiwan. METHODS The population included 4383 women aged 16-78 seeking HPV testing at primary gynecologic practitioners regardless of their cervical cytology results. HPV DNA was identified from cervical swabs using semi-nested polymerase chain reaction with MY11, MY09/HMB01, and MY11/bioGP6+ primers. Genotyping for high-risk HPV (HR-HPV) was done separately by a HR-HPV chip, which contained 13 type-specific oligonucleotides on a nylon membrane. RESULTS The overall HPV prevalence was 19.3% (849/4383), 11.1% (488/4383) were confirmed as HR-HPV positive. Among the women with HR-HPV infection, HPV-16 was the most prevalent type (22.1%; 108/488), followed by HPV-52 (21.3%; 104/488), and HPV-58 (19.9%; 97/488). Multiple infections were detected in 73 women (15.0%; 73/488). For women with age 30 or younger, the overall HPV and HR-HPV prevalence were 32.0% and 20.7%, respectively, which were significantly higher than those of women age older than 30 (17.2% and 9.5%, P < 0.001). More multiple infections (22.1% vs. 12.4%) were also found in women with age 30 or younger (P = 0.021). However, the relative contribution of types to the overall HR-HPV positive among different age groups remains the same. CONCLUSIONS Our results showed an HPV prevalence that is similar compared with worldwide levels. HPV prevalence and multiple infections rate were decreasing across the age groups. Unlike most previous studies, the relative high prevalence of HPV 52 and 58 among South Taiwan women has important implications in vaccine prophylaxis.

Abstract
"High-risk" HPVs (HR-HPV) have sharply different prevalences and there is evidence to suggest this may vary according to regions. Accurate description of HR-HPV circulation is a key feature for the rational design of prevention and screening campaigns. To gain insight into HR-HPV circulation in Tunisia, a pilot study was carried out on 64 healthy prostitutes working in the Tunis area. HPV detection and typing were carried out by MY09/MY11 PCR and restriction fragment length polymorphism (RFLP). A selected set of samples was also assayed by Gp5+/Gp6+ PCR and typed by direct sequencing. Out of 64 women, 28 were HPV positive. HPV-16 and HPV-58, both members of the genus Alpha-Papillomavirus, species 9, accounted for 10 and 7 cases with a prevalence rate of 38% and 27%, respectively. HPV-82, a member of species 5, ranked third with four cases (approximately 15%). Types 31, 33, 35; all members of species 9 were each detected once (approximately 4%) while neither HPV-18 nor related members of species 7 were detected. Type 72 and 83, both members of species 3, were the only low-risk types, each detected only once (4% each). Two samples could not be typed. The prevalence of HPV types appeared sharply different from that of neighboring areas. Should the existence of epidemiological pockets be confirmed by larger, more detailed studies, screening and vaccine campaigns will have to be designed carefully taking into account the actual epidemiological context of the target population.

Abstract
We conducted a hospital-based case-control study in Algiers, Algeria. A total of 198 cervical carcinoma (CC) cases (including 15 adeno- and adenosquamous carcinomas) and 202 age-matched control women were included. Human papillomavirus (HPV) DNA in cervical cells was evaluated using a PCR assay. Odds ratios and corresponding confidence intervals were computed by means of unconditional multiple logistic regression models. HPV infection was detected in 97.7% of CC cases and 12.4% of control women (OR = 635). Nineteen different HPV types were found. HPV 16 was the most common type in both CC cases and control women, followed by HPV 18 and 45. Twelve types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 66 and 73) were found as single infections in CC cases. Multiple HPV infections did not show a higher odds ratio for CC than single infections. In addition to HPV infection, husband's extramarital sexual relationships with other women (OR = 4.8) or prostitutes (OR = 3.2), residing in a rural environment for most of one's life (OR = 4.9) and indicators of poor sanitation or poor hygiene were the strongest risk factors for CC. Oral contraceptive use was unrelated to CC risk, while multiparity emerged as a significant risk factor after adjustment for sexual habits. Intrauterine device users showed a lower CC risk than nonusers. The role of major risk factors, except inside toilet, was confirmed in the analysis restricted to HPV-positive women. The distribution of HPV types in CC cases and control women in Algeria is more similar to the one found in Europe than the one in sub-Saharan Africa, where HPV 16 is less prevalent. A vaccine against HPV 16 and 18 may be effective in more than 3/4 of CCs in Algeria.
