Epidemiology and genotype distribution of human papillomavirus (HPV) in women of Sardinia (Italy)

The human papillomavirus (HPV) infection is necessary for the development of cervical cancer. Our study aims to evaluate the rate of HPV circulation in our population, to identify the prevalent genotypes and to establish correlation with cervical abnormalities. Furthermore, the awareness of women about HPV issues was investigated.This study included 864 women attending the Oncologic Prevention Service for their routine Pap test screening or the Health Promotion Mother-Child Service for counselling about sexual activity, from July 2006 to September 2007. All the participants gave their informed consent to be enrolled in the study and were invited to fill in a questionnaire about the socio-cultural state, sexual activity and awareness about HPV. The women samples were tested for HPV-DNA and HPV genotypes: any type of HPV-DNA was detected in 31.0% of the women; single or multiple infections sustained by HPV-16 or HPV-18 represented 43.5% of all HPV infections, accounting for infections in 11.8% of the recruited women. The HPV and high-risk HPV (HR-HPV) prevalence significantly declined in women older than 46 years. The Pap test result was available in 490 women; 48.1% of the Pap test positive women had also an HPV infection and among these 22.7% were infected by HPV-16 and/or HPV-18 genotype, while 51.9% (94/181) were HPV negative. The analysis by binary logistic regression showed that genotype 16 and/or 18 is a risk factor for the Pap positive test with a odds ratio (OR) of 2.9 (95% C.I. 1.4–5.9) and 3.6 (95% C.I. 1.58–8.42) respectively, while age is a protective factor (OR 0.97, C.I. 95% 0.96–0.99); furthermore, the mean age at the first sexual intercourse and the mean number of partners since the beginning of sexual activity, were statistically associated with the risk of HPV infection. More than half of women were aware about HPV, its sexual transmission and of its correlation with cervix cancer.Our findings evidenced that HPV infection is frequent in women aged 18–46 years in Sardinia and particularly that 16 and 18 HPV genotypes are detectable in more than 40% of the infected women. The proportion of women informed about HPV issues is sufficient to guarantee an aware approach to HPV vaccination.     

Nucleotide and phylogenetic analysis of human papillomavirus types 6 and 11 isolated from recurrent respiratory papillomatosis in Brazil

There are few studies about the distribution of natural molecular variants of low-risk HPVs. Our aim was to evaluate the E6 early gene variability among HPV-6 and HPV-11 isolates detected in recurrent respiratory papillomatosis (RRP) samples obtained in a cohort of Brazilian patients. We also performed a phylogenetic analysis in order to compare nucleotide sequences identified in our study with previously reported isolates from different anatomic sites (laryngeal papillomas, genital warts, cervical cancer and anal swabs) obtained from other parts of the world to determine the phylogenetic relationships of variants detected in Brazil. The complete coding region of the E6 gene of 25 samples was cloned and sequenced: 18 isolates of HPV-6 (72%) and 7 isolates of HPV-11 (28%). A total of four different HPV-6 genomic variants and two HPV-11 genomic variants was identified. It was not possible to correlate specific variants with disease severity. Phylogenetic trees for both HPV types were constructed enclosing both E6 sequences detected in our study and formerly published sequences. In both phylogenetic trees, the sequences from Brazil did not group together. We could not establish a geographical association between HPV-6 or HPV-11 variants, unlike HPV-16 and HPV-18.     

Human papillomavirus infection among human immunodeficiency virus-infected women in Maharashtra,India

Introduction

Frequency and distribution of HPV types in HIV-infected women with and without cervical neoplasia and their determinants have not been widely studied in India. We report and discuss HPV prevalence and type distribution in HIV-infected women.

Methods

HPV genotyping was done using cervical samples from 1109 HIV-infected women in a cross-sectional study.

Results

Any HPV was detected in 44.8% and high-risk ones in 41.0% women. Frequency of single and multiple high-risk infections were 26.7% and 14.3%, respectively. Frequencies of high-risk HPV infections in women with and without cervical neoplasia were 73.5% and 37.6%, respectively. HPV16 was the most common genotype, present in 11.5%, and 58.5% of women with cervical intraepithelial neoplasia (CIN) 2 and 3. Other most common high-risk HPV types in CIN 2–3 lesions were HPV 31 (22.6%); 56 (13.2%); 18 and 68a (11.3%) and 33, 35 and 51 (9.4%); and 70 (7.5%). Women under 30 or over 44 years, no abortions, and women with diagnosis of HIV infection within the last 5 years were at high risk of multiple oncogenic HPV infection.

Conclusion

We observed a very high frequency of high-risk HPV and multiple infections in HIV-infected women.     

Identification of human papillomavirus type 16 variants circulating in the Calabria region by sequencing and phylogenetic analysis of HPV16 from cervical smears

Sequence analysis of HPV16 isolates reveals the presence of genome variants with characteristic mutations. The HPV16 variants have different geographical distribution and diverge into four phylogenetic lineages (A, B, C and D) and 16 sub-lineages: A1, A2, A3 (previously known as European variants), A4 (Asian variant), B1, B2, B3, B4, C1, C2, C3, and C4 (African variants), D1 (North-American variant), D2, D3 (Asian-American variants) and D4. Population studies showed that infections with viruses belonging to specific HPV16 sublineages confer different risks of viral persistence and cancer. In this study, 39 HPV16-positive cervical smears from European women living in Calabria (Italy) were analyzed for the presence of HPV16 variants. Cervical DNA extracts were processed by PCR to amplify L1, the Long Control Region (LCR), E6 and E7, which were sequenced. The sequences were concatenated and the 3169 nucleotides long fragments were characterized by BLAST and phylogenetic analysis. A total of 96 Single Nucleotide Polymorphism (SNPs) were detected, 29 of which mapping in the L1, 45 in the LCR, 15 in the E6 and 7 in the E7. The most common SNP was the T350G (29/39 samples, 74.4%), causing the L83 V amino acid change in the E6. Most of the HPV16 isolates (89.7%) had 99% of nucleotide (nt) identity to members of the A1 and A2 sublineages, while 4 isolates had 99% nt identity to members of the B2, B4, C1 and D4 sublineages. In conclusion, viruses belonging to the A1, A2, B2, B4, C1 and D4 HPV16 sublineages were found to circulate in the Calabria region.     

Anal HPV genotypes and related displasic lesions in Italian and foreign born high-risk males

Anal intraepithelial neoplasia and anal cancer are closely related to infection from high-risk Human Papilloma Virus (HPV) genotypes. Since HPVs involved in disease progression are reported to vary by geographical regions, this study focuses on HPV genotypes spectrum in 289 males attending a Sexual Transmitted Diseases (STD) unit according to their nationality. Anal cytology, Digene Hybrid Capture Assay (HC2) and HPV genotyping were evaluated in 226 Italian (IT) and 63 foreign born (FB) subjects, recruited between January 2003 and December 2006. FB people were younger (median 32y-IQR 27–35 vs 36y-IQR 31–43, respectively; Mann–Whitney test p < 0.0001) and had a higher rate of abnormal results (≥atypical squamous cells of undetermined significance (ASCUS)) on anal cytology (95.0% vs 84.04%) (p = 0.032; OR 3.61; 95% CI 1.04–1.23). HPV-16 is by far the most common genotype found in anal cytological samples independently from nationality while differences in distribution of other HPV genotypes were observed. The probability of infection from high-risk HPVs was higher in FB (OR 1.69; 95% CI 1.07–2.68) and is due to a higher rate of HPV-58 (OR 4.98; 95% CI 2.06–12.04), to a lower rate of HPV-11 (OR 0.35; 95% CI 0.16–0.77), to the presence of other high-risk genotypes (HPV-45, HPV-66, HPV-69). Multiple infections rate was high and comparable between IT and FB people. The relative contribution of each HPV genotype in the development of pre-neoplastic disease to an early age in the FB group cannot be argued by this study and more extensive epidemiological evaluations are needed to define the influence of each genotype and the association with the most prevalent high-risk HPVs on cytological intraepithelial lesions development.

Population-based study of human papillomavirus infection and cervical neoplasia in Athens, Greece

The aim of our study is to describe the prevalence of the different HPV types in women with pre-neoplastic lesions of the cervix in Greece. Cervical scrapes from 841 women were obtained for both cytological evaluation and analysis for the presence of HPV DNA. PCR was performed on specimens from these 841 women. The Pap test results were normal or showed benign cellular changes in 45.8% of the women, atypical squamous cells of undetermined significance (ASCUS) in 23.2%, low-grade squamous intra-epithelial lesion (LSIL) in 27.9% and high-grade squamous intra-epithelial lesion (HSIL) in 3.1%. HPV DNA was demonstrated in 23.6% of cytologically normal women. We detected HPV in 60% of the total samples. Of these, HPV-16 was the most common HPV DNA detected. Interestingly, HPV-58 was inversely correlated with positive cytological findings. A clear pattern of decreasing prevalence of HPV with age was also observed. Our results indicate that HPV infections, especially those with HPV-16, represent a significant public health concern in Greece.

Human papillomavirus type 16 long control region and E6 variants stratified by cervical disease stage

ObjectiveCertain intra-type variants of HPV16 have been shown to be associated with an increased risk of developing high grade cervical disease, but their potential association is confounded by apparent geographic and phylogenetic lineage dependency. The objective of this study was to evaluate the relationship between HPV16 sequence variants and cervical disease stage in monospecific infection samples from a single lineage (European, EUR) in England.MethodsOne hundred and twelve women singly infected with HPV16 and displaying normal and abnormal cytology grades were selected. An 1187 bp fragment encompassing the entire LCR and a portion of the E6 open reading frame was sequenced to identify intra-type variants. Intra-type diversity was estimated using Shannon entropy.ResultsAlmost all samples (110/112; 98%) were assigned to the EUR lineage, one sample was classified as European-Asian (EAS) and another African (Afr1a). The mean pairwise distance of the EUR sequences in this study was low (0.29%; 95%CI 0.13–0.45%) but there were nevertheless several sites in the LCR (n = 5) and E6 (n = 2) that exhibited a high degree of entropy. None of these sites, however, including the T350G non-synonymous (L83V) substitution in E6, alone or in combination, were found to be associated with cervical disease stage.ConclusionsDespite using single infection samples and samples from a single variant lineage, intra-type variants of HPV16 were not differentially associated with cervical disease. Monitoring intra-lineage, site-specific variants, such as T350G, is unlikely to be of diagnostic value.     

不同型别人乳头状瘤病毒感染与宫颈病变程度的关系

目的探讨人乳头状瘤病毒(HPV)感染患者的各HPV型别分布,及各型别HPV感染与宫颈不同程度病变的关系。方法采用核酸分子快速导流杂交基因微阵列分型检测技术,分析740例女性HPV感染者的HPV型别,同时检测宫颈病变程度。结果在740例HPV感染者中常见的21种亚型均被检出,排在前3位的亚型分别为16、58、52;高危型HPV混合低危型HPV的混合感染与单一高危型HPV感染和多种高危型HPV混合感染之间,宫颈不同程度病变差异无统计学意义,而以上几种感染类型与低危HPV感染相比,宫颈病变程度差异有统计学意义(均P<0.01),多元logistic回归分析显示,感染16型HPV(OR=3.56,P<0.01),58型HPV(OR=1.29,P<0.05)使宫颈癌患病风险大大增加;把宫颈上皮内瘤变分为低等级(CINⅠ)和高等级(CINⅡ、CINⅢ)病变,以不同程度的宫颈上皮内瘤变作为分析因素进行二元logistic回归,显示6型HPV(OR=6.99,P<0.01)、11型HPV(OR=5.92,P<0.01)感染将使感染者宫颈上皮内瘤变CINⅠ的风险大大升高。结论相对于低危型HPV,感染高危型HPV是宫颈病变加重的重要因素;高危型的16、18型HPV感染引起宫颈癌的患病风险增加,低危型的6型、11型HPV感染则更易引低级别的宫颈上皮内瘤变的发生。     

Variations of human papillomavirus type 58 E6, E7, L1 genes and long control region in strains from women with cervical lesions in Liaoning province, China

Infection with certain types of human papillomaviruses (HPVs) is a risk factor for the development of cervical cancer. HPV type 58 (HPV 58) is prevalent among Chinese women. The intratype sequence variants differ in oncogenic potential and their prevalences vary across geographic regions. The objective of this study was to analyze the variations of HPV 58 E6, E7, L1 genes and long control region (LCR) in a large samples collected from northeastern Chinese women with cervical lesions. A total of 2938 cervical samples were collected and tested for HPV type using a chip hybridization assay. The E6, E7, L1 genes and LCR of HPV 58 strains were amplified and the amplicons were subjected to direct nucleotide sequencing for variation identification. A total of 235 specimens were HPV 58 positive. High proportions of HPV 58 E6 (83.8%), E7 (76.7%), L1 (90.8%) genes and LCR (91.4%) variants were identified in strains from Chinese women. The most frequently observed variations were C307T (52.4%) in E6, T744G (74.9%) in E7, A6014C (56.9%) in L1 genes and C7266T, A7714G (55.2%) in LCR. For the E6 gene, nine nucleotide variations were identified. Among them, the A140G (T11A), A184C (E25D), G266C (V53L) and A313G were novel variations. Sequencing of the E7 gene revealed four typical nucleotide changes: G761A (G63D), G694A (G41R), T803C (V77A) and T744G. In the L1 gene, 39 nucleotide variations and 13 amino acid substitutions were identified. Among these mutations, 21 variations are reported here for the first time. Lineage A of HPV 58 was found in 142 of 174 strains (81.6%). The most prevalent HPV 58 variants in Chinese northeastern women belongs to lineage A. Novel variations in E6 and L1 genes were also reported. These findings provide new data regarding E6 and L1 gene variations of HPV 58 from women in northeast China.

A meta-analysis of human papillomavirus type-distribution in women from South Asia: implications for vaccination

OBJECTIVE: To determine human papillomavirus (HPV) prevalence and type-distribution in women from South Asia, with and without cervical lesions, in order to estimate the impact of an HPV 16/18 prophylactic vaccine in this region and to assess additional types that should be incorporated in new vaccines. METHODS: A meta-analysis was conducted that included studies using polymerase chain reaction to detect HPV-16, -18, -6, -11 and at least one other HPV type, with a minimum of 20 cases in each grade of lesion. Total as well as type-specific prevalence of various HPV types were estimated, stratified by cervical lesion grade, using Stata 9.0 software package. RESULTS: Nine studies from India fulfilled the inclusion criteria. A total of 558, 52, 52 and 3061 women, respectively with invasive cervical cancer (ICC), high-grade squamous intraepithelial lesions (HSIL), low-grade squamous intraepithelial lesions (LSIL) and normal cytology/histology were included. Overall HPV prevalence was 94.6%, 86.5%, 65.4% and 12.0% in women with ICC, HSIL, LSIL and normal cytology/histology, respectively. In ICC, HPV-16 was the predominant type (64.8%), followed by HPV-18, -45, -33, -35, -58, -59 and -31. The estimated HPV-16/18 positive fraction was 78.9% in women with ICC (87.7% in North and 77.2% in South India), 61.5% with HSIL, 30.8% with LSIL and 3.9% in women with normal cytology/histology. There was no difference in overall HPV prevalence in cervical cancer between North and South India (P=0.063). However, HPV-16 and -45 appeared to be more prevalent in North India (P=0.018 and 0.013, respectively), while HPV-35 appeared to be more prevalent in South India (P=0.033). CONCLUSION: It is estimated that HPV-16/18 vaccines will provide over 75% protection against ICC in South Asia. HPV-45, -33, -35 and -58 account for an additional 20% of cervical cancer in this region. The addition of these additional HPV types in a second-generation vaccine could provide optimal cervical cancer prevention in this region.
