Infections caused by the human immunodeficiency virus (HIV) and human papillomavirus (HPV) cause thousands of deaths worldwide each year. So far, there has been no consensus on whether there is a direct relationship between the incidence of neoplasms and the immunosuppression caused by HIV that could help understand if coinfection increases the likelihood of cervical cancer. The objective of the study was to identify the presence of genetic variants of HPV in a group of HIV-positive women and their possible association with cervical cancer. Cervical samples were taken from HIV-positive patients for cytological analysis to identify the HPV genotype by polymerase chain reaction (PCR) and sequencing. The most preva¬lent L1 capsid protein mutations in the HPV genotype were ana¬lyzed in silico. Various types of HPV were identified, both high-risk (HR) and low-risk (LR). The most prevalent genotype was HPV51. Analysis of the L1 gene sequences of HPV51 isolates showed nucleo¬tide variations. Of the samples analyzed in Puebla, Mexico, HPV51 had the highest incidence (17.5%, 7/40). Different mutations, which could be used as population markers, were detected in this area, and they have not been reported in the L1 databases for HPV51 in Mexico. Genotypes 6, 14, 86, 87, 89, and 91, not detected or reported in samples from patients with HPV in Mexico, were also identified. Data from the population analyzed suggest no direct relationship between HIV immunosuppression and cervical cancer, regardless of the high- or low-risk HPV genotype. Furthermore, it is possible to develop regional population markers for the detection of HPV based on the mutations that occur in the sequence of nucleotides analyzed.

There are limited data on human papillomavirus (HPV) type-specific cervical cancer risk among human immunodeficiency virus (HIV)-positive women. Previous studies have suggested that HPV 16 would be relatively less important as a causative agent among HIV-positive compared with HIV-negative women. This study investigates HPV type-specific cervical cancer risk in a population in which HIV is endemic. At the Central Hospital, Maputo, Mozambique, 221 cervical cancer cases and 203 hospital-based controls were consecutively enrolled. HPV typing from cervical samples, HIV testing and recording of socio-demographic factors were performed. Logistic regression modelling was used to assess HPV type-specific risk and effect modification between HIV and HPV infection. Infection with HPV 16, 18 and ‘high-risk non-HPV 16/18 types’ (HPV 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59) was associated with cervical cancer in both crude and adjusted analyses. HPV 16 and 18 were the most common types detected in cancer biopsies among both HIV-negative and HIV-positive women. There was no significant evidence of effect modification between any HPV type and HIV infection, and there were no significant differences in the HPV type-specific prevalence when cervical cancers among HIV-positive and HIV-negative women were compared. Within the limitations of the study, the relative importance of different HPV types in cervical carcinogenesis appears not to be modified greatly by HIV infection, suggesting that HPV vaccines might not need to be type-specifically modified to be suitable for populations where HIV is endemic.

Background Although an increased prevalence of plantar verrucae has been associated with human immunodeficiency virus (HIV) infection, human papillomavirus (HPV) typing studies have not been published about this patient population. We sought to determine the prevalence of HPV types in plantar verrucae of HIV-positive (HIV+) and HIV-negative (HIV–) individuals. Methods Thirty-nine plantar verruca lesions in 17 individuals were examined. Nine participants were HIV+ and eight were HIV–. Detection of HPV was performed by polymerase chain reaction using two sets of primers: MY09/MY11. The type of HPV was determined by hybridization to 38 different HPV types. Clinical types of verrucae were correlated to the HPV strain identified in each lesion. Results Of the 39 plantar verruca samples, 38 typed to HPV-2, HPV-27, and HPV-57 strains in HIV+ and HIV– individuals. Specifically, a large proportion of the samples from HIV– individuals typed as HPV-27 (87.5%), and HPV-2 was the predominant type identified in HIV+ individuals (50%). No rare or atypical HPV types were found in either group. We identified HPV-2 and HPV-27 in 96% of verruca plantaris clinical type. Mosaic warts typed to HPV-27 and HPV-57, and 80% of punctate verrucae typed to HPV-57. Conclusions This study presents an increased prevalence of HPV-2, HPV-27, and HPV-57 in plantar verrucae in this study population and provides insight into the occurrence of these types in HIV+ and HIV– individuals.

Abstract Background: Human papillomavirus type 30 (HPV30) is involved in cervical diseases. In human immunodeficiency virus (HIV) positive women, the prevalence HPV30 is almost the same as HPV16. However, HPV30 has seldom been investigated. In order to better understand the prevalence and intratype lineage distribution of HPV30 in China, HPV30 infection among women with normal cytology was investigated.Methods: Prevalence of HPV30 was investigated by the screening of type specific polymerase chain reaction (PCR); intratype lineage distribution was performed by the phylogenetic analysis of the L2 DNA sequences of HPV30 isolates; the diversity of genetic variants of HPV30 isolates was also evaluated. Results: (1) The infection rate of HPV30 was 0.56% (9/1600). (2) All the nine HPV30 isolates belonged to lineage A, none belonged to lineage B. (3) Compared with the HPV30 prototype reference, 87 variations including 79 substitutions, four insertions and four deletions were observed in this study. (4) Sample 4 contained a C base deletion of the E2 gene resulting in an amino acid sequence shift. (5) Sample had a truncated L2 protein.Conclusions: The infection rate of HPV30 is 0.56% in this study. All of the HPV30 isolates belongs to lineage A. Natural L2 and E2 defective isolates of HPV30 were found.

Purpose There is a dearth of data on clearance of cervical human papillomavirus (HPV) infection among women in West Africa. We examined the clearance of low-risk (lr) and high-risk (hr) cervical HPV infections, and the factors associated with these measures in HIV-negative and HIV-positive women. Methods We studied 630 Nigerian women involved in a study of HPV infection using short polymerase chain reaction fragment-10 assay and line probe assay-25. Research nurses used a cervical brush to collect samples of exfoliated cervical cells from all the study participants. Cox proportional hazards models were used to estimate associations between HIV and HPV infections. Results The mean age of the study participants was 38 (standard deviation, ± 8) years; 51% were HIV positive. The rate of clearing any HPV infection was 2.0% per month among all women in the study population, 2.5% per month among HIV-negative women, and 1.6% per month, among HIV-positive women. The clearance rate per 1,000 person-months of observation for any lrHPV infection and any hrHPV infection were 9.21 and 8.83, respectively, for HIV-negative women, and 9.38 and 9.37, respectively, for HIV-positive women. In multivariate models, the hazard ratios for HIV-positive compared with HIV-negative women were 0.85 (95% CI, 0.51 to 1.43; P = .55) and 0.95 (95% CI, 0.54 to 1.65; P = .85) for cleared infections with any lrHPV and any hrHPV, respectively. The hazard ratio for HIV-positive compared with HIV-negative women was 0.39 (95% CI, 0.17 to 0.88; P = .02) for cleared infections with any multiple HPV and 0.13 (95% CI, 0.03 to 0.58; P = .007) for cleared infections with multiple hrHPV. Conclusion In this study population, we observed that HIV-positive women were less likely to clear infections with multiple hrHPV types.

Human immunodeficiency virus (HIV)-positive women have high rates of cervical squamous intraepithelial lesions (SIL) and concurrent human papillomavirus (HPV) infections with a variety of genotypes whose oncogenic risk is poorly documented. The prevalence and persistence of HPV genotypes and HPV16 variants were analysed in 112 HIV-positive and 115 HIV-negative Italian women. HIV-positive women were more likely than HIV-negative women to be infected by HPV at the initial examination (39.3 vs 13.9 %, P<0.001) and to have a higher period prevalence of HPV infection over a 3-year follow-up (43.8 % vs 17.4 %, P<0.001), regardless of CD4+ cell counts and anti-retroviral therapy. ‘High-risk’ and ‘probable high-risk’ HPVs (types 16, 18, 31, 33, 35, 45, 52, 58 and 66), among the 20 different viral genotypes identified, were predominant in HIV-positive (33.9 %) compared with HIV-negative (13.9 %) women. Among HIV-infected women, with normal cytology as well as with SIL of any grade, the most common genotypes were HPV16 followed by HPV81, -58, -72, -33 and -62. HPV16 isolates from 18 HIV-positive and eight HIV-negative women were classified into variant lineages based on sequencing analysis of E6 and E7 genes and the long control region. Whilst the HPV16 G350 European variant was prevalent in both HIV-positive (10.7 %) and -negative women (3.5 %), HPV16 African 2 variant was only detected in HIV-positive women (3.6 %), suggesting different sexual mixing behaviours. The increased prevalence of uncommon viral genotypes and HPV16 variants in HIV-positive Italian women underscores the need to target a wide range of HPV types in cervical screening of high-risk women.

Background: Cervical cancer remains the major public problem worldwide and the most common gynaecological malignancy in the developing world, particularly in sub-Saharan Africa.Aim: To determine the prevalence of abnormal cervical cytology amongst women with and without human immunodeficiency virus (HIV) and examine the association between HIV and histological grading.Setting: The study was conducted in Limpopo province, which is the northernmost province of South Africa. The province has five district municipalities with one tertiary, five regional and thirty four district hospitals.Methods: We retrospectively reviewed cervical cancer cases in Limpopo province (LP) of South Africa, using data collected routinely by the National Health Laboratory Services (NHLS). The data on smears submitted for cytology between 2013 and 2015 were extracted from the Central Data Warehouse (CDW) database.Results: A total of 84 466 women were screened for cervical cytology smears. Their mean age was 39.8 ± 13.6 years, with range from 15 to 113 years; 77.2% were in the age group 30 years and older and 19.6% had an abnormal cervical cytology result. Overall, 46.4% of the women screened for cervical cancer were HIV infected. A significantly higher proportion of HIV-positive women had abnormal cytology than HIV-negative women (31.8% vs. 9.2%).Conclusion: The prevalence of abnormal cytology amongst HIV-positive women is relatively high, and the risk appears to be significantly greater in all age groups. This finding highlights the need to ascertain HIV status of all women presenting with cervical cancer.

Background: Human papillomavirus (HPV) infection is now a well-established cause of cervical cancer and other anogenital cancers. An association between human immunodeficiency virus (HIV) infection and higher HPV incidence and prevalence are commonly reported. This study was conducted to demonstrate HPV prevalence, genotypes and its characteristics, according to the HIV status in women from Maputo in Mozambique. Methods: A total of 233 participants with ages ranging from fourteen to forty-five were included. Cervical samples were collected, DNA extracted, and HPV genotyping was performed using the HPV Direct Flow CHIP Kit. Results: In total, 177 HIV-negative and 56 HIV-positive women were included in the analysis. The overall HPV prevalence was 63% and was significantly higher among HIV-positive women (79% versus 58% among HIV-negative women; p = 0.005). The prevalence of multiple HPV type infections was 32%. High-risk HPV types 52, 68, 35, 18 and 16 were the most frequent. A higher proportion of HIV-positive women had multiple HPV types compared with HIV-negative women. Conclusions: This study demonstrated a high prevalence of HPV in the study cohort. HIV-positive women were identified as having the highest HPV prevalence and infection with multiple HPV types across all ages. High-risk genotypes were the most commonly found.
