HPV and HIV Coinfection in Women from a Southeast Region of Romania—PICOPIV Study. Medicina (B Aires) 2022; 58:medicina58060760. [PMID: 35744023 PMCID: PMC9231193 DOI: 10.3390/medicina58060760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 05/24/2022] [Accepted: 05/31/2022] [Indexed: 11/28/2022] Open
Abstract
Background and Objectives: Romania faces one of the highest cervical cancer burdens in Europe though it is a preventable cancer through population screening by cytology and human papillomavirus (HPV) detection. Also, it has one of the highest incidences of human immunodeficiency virus (HIV) infection. HPV and HIV coinfection are frequently encountered. The aim of study was to establish the prevalence of HPV infection among HIV-positive women in Southeast Region of Romania, to genotype high risk HPV types -and to correlate the results with clinical data and cytological cervical lesions. Materials and Methods: 40 HIV-positive women were screened for HPV types and for cytological cervical lesions. The findings were evaluated in correlation with CD4 cell counts, HIV viral load, age at first sexual intercourse, number of sexual partners, vaginal candidiasis, and Gardnerella using statistical methods. Results: 19/40 (47.5%) women were positive for HPV types, 63.15% infected with single HPV type and 36.85% with multiple HPV types. The most frequent types were type: 31 (42.1%), 56 (31.57%), 53 (15.78%). On cytology, 34 (85%) women were found with NILM of which 38.23% were HPV-positive. Fifteen percent of women had abnormal cytology (three ASC-US, three LSIL), and all of them were HPV-positive. Through analyzing the value of CD4 count, women with CD4 count ≤ 200 cells/μL were found to be significantly more likely to be infected with HPV; meanwhile there was no correlation between the detection of HPV types and HIV viral load. Candida or Gardnerella were more often associated with HIV-positive women with HPV, than in women without HPV. Conclusions: Infection with HPV types is common among HIV-positive women in the Southeast Region of Romania and it is associated with age at the beginning of sexual life, number of sexual partners, CD4 value, vaginal candidiasis, and Gardnerella infection.

Abstract
Aims and background The aim of this study was to compare the local immune response in two groups of patients with high-grade cervical intraepithelial squamous lesions (SIL): one with HIV infection and the other with HPV infection alone. Materials and methods 16 conization specimens (8 from HIV-infected and 8 from non-HIV-infected patients) of HPV-related, high-grade SIL were selected. The specimens from non-HIV patients were considered as controls. The total number of Langerhans cells, CD4 and CD8 cells present in 10 field areas (3.120 mm2) was recorded in each case. In HIV patients CD4 and CD8 peripheral counts were performed immediately before surgery. Results The CD4/CD8 ratio never exceeded 0.71, whereas the lowest ratio in controls was 0.81: this difference was statistically significant (P=0.0009). The mean number of Langerhans cells was markedly reduced in the high-grade SILs in the HIV patients in comparison with controls (P=0.001). The number of CD4 cells and the CD4/CD8 ratio correlated with the peripheral CD4 count (P=0.001 and 0.02). Conclusions In our study a marked local impairment of cervical immunoreactivity was observed, which may play a major role in the progression of these lesions in HIV-infected women.

Abstract
OBJECTIVES To evaluate a possible mechanism of human immunodeficiency virus (HIV) and human papillomavirus (HPV) interaction, we have identified the cervical tissue compartments that harbor HIV. MATERIALS AND METHODS We studied 39 paraffin-embedded, cervical conization specimens with high-grade cervical intraepithelial neoplasia (CIN3) occurring in HIV-infected women. From selected intraepithelial HPV-positive nonulcerated specimens (confirmed by in situ hybridization), we obtained serial 4- to 5-μm-thick sections that were stained with hematoxylin and eosin, anti-S100 protein, and anti-CD4. The presence of intramucosal Langerhans' cells or dendritic cells or CD4-positive cells was recorded. Three consecutive, nonmicrodissected, full-thickness sections of the same specimens were used for polymerase chain reaction (PCR) analysis (group A). Three other uncovered, consecutive sections from the same blocks were examined with an inverted microscope, and full-thickness specimens of mucosa were dissected from the underlying cervical stroma, were gently removed, and were used for PCR (group B). The quality of DNA was checked by HLA-DQa amplification; then a nested PCR for HIV proviral DNA was performed. RESULTS Of group A, 5 of 39 cases (12.8%) were positive, whereas HIV was not detected in the microdissected sections of group B, with or without intraepithelial Langerhans' or CD4 cells. CONCLUSIONS HIV does not affect cervical epithelium. The absence of infected Langerhans' or dendritic cells (or both) indicates a migration to the proximal lymph nodes of the in ….

Abstract
OBJECTIVES Persistent human papillomavirus (HPV) infections can cause intraepithelial neoplasia of the lower genital tract. Immune-compromised women have higher rates for all lower genital tract intraepithelial neoplasia. We wish to study the distribution of genital intraepithelial neoplasia in women with and without an immune system. METHODS The study consisted of 343 women with an abnormal genital lesion or cervical cytology who were referred to a gynecologic oncologist. All patients underwent vulva, vaginal, cervical and anal colposcopy. Any lesion detected was biopsied. Demographic and medical data were collected. The Chi-square test was used to determine the relationship between immunosuppression status and various variables, including sites of intraepithelial neoplasia. RESULTS Immune-compromised women (N = 33) are more likely than immune-competent women (N = 310) to have intraepithelial neoplasia of the vulva (p < 0.05) and vagina (p < 0.05), but not more likely to have intraepithelial neoplasia of the anus or cervix. Immune-compromised women are more likely than immune-competent women to have multifocal intraepithelial neoplasia (p < 0.001). In addition, immune-compromised women are more likely to have higher grade disease of the vulva and vagina (p < 0.05), and no more likely to have higher grade disease on the cervix or anus than immune-competent women. CONCLUSION Women with conditions suppressing the immune system are at higher risk for HPV-related disease outside of the cervix and for worse HPV-related diseases than immune-competent women. This study highlights the need for vigilant evaluation of the complete lower genital tract in women with immune-compromised systems.

Abstract
Objective. To assess the prevalence and identified associated risk factors for precancerous cervical cancer lesions among HIV-infected women in resource-limited settings in Kenya. Methods. HIV-infected women attending the ART clinic at the Nazareth Hospital ART clinic between June 2009 and September 2010. Multivariate logistic regression model with odds ratios and 95% confidence intervals (CI) were estimated after controlling for important covariates. Result. A total of 715 women were screened for cervical cancer. The median age of the participants was 40 years (range 18-69 years). The prevalence of precancerous lesions (CINI, CINII, CIN III, ICC) was 191 (26.7%). After controlling for other variables in logistic regression analysis, cervical precancerous lesions were associated with not being on ART therapy; whereby non-ART were 2.21 times more likely to have precancerous lesions than ART patients [(aOR) = 2.21, 95% CI (1.28-3.83)]. Conclusion. The prevalence of precancerous cervical lesions was lower than other similar settings. It is recommended that cancer screening of HIV-infected women should be an established practice. Availability and accessibility of these services can be done through their integration into HIV. Prompt initiation of HAART through an early enrollment into care has an impact on reducing the prevalence and progression of cervical precancerous lesions.

Abstract
OBJECTIVE To identify characteristics of the cell-mediated immune (CMI) response to human papillomavirus-16 (HPV) E7 viral peptide pools to help the formulation of therapeutic vaccines. DESIGN Prospective study. Population. Korean women. SETTING University hospital. METHODS From December 2008 to August 2010, 33 HPV-16-positive patients, seven patients exhibiting a high-risk HPV infection other than HPV-16 with grade 2/3 cervical intraepithelial neoplasm (CIN2/3), and nine healthy control donors were enrolled. MAIN OUTCOME MEASURES CMI response to synthetic HPV-16 E7 overlapping peptide pools using the IFN-γ ELISPOT assay. RESULTS The E7 sequence comprising amino acids 16-55 was a major immunogenic region. The CMI response to HPV-16 E7 is highly type-specific. The follow-up CMI response may last longer than expected after the lesion is resected. CONCLUSIONS We found that the E7 sequence comprising amino acids 16-55 is a major immunogenic region that is critical for the T-cell-mediated immune response with CIN2/3 or cervical cancer. The identification of CMI responses to HPV-16 E7 peptide pools may provide insight into therapeutic vaccine trials for the control of HPV-associated diseases.

Abstract
Cervical cancer (CC) is the third most common cancer in women worldwide; however, CC is a preventable disease, and much effort should be done to prevent it. Persistence of high-risk HPV infection is the strongest epidemiologic risk factor for CC, however it is not sufficient for development of the disease it cofactors should be present. In 2004; IARC listed cervical cancer among those causally related to smoking. Smoking interferes with incidence and prevalence of HPV infection and is associated with cervical intraepithelial neoplasia and invasive CC. Multiple factors seem to intervene on cervical carcinogenesis related with tobacco, especially by direct local carcinogenic effect and local immunosuppression. Smoking addition is also closely related with other confounding factors, like unfavorable psychosocial events, systemic immunity, contraception, and nutrition, which got difficult epidemiologic evaluation of smoking role on cervical carcinogenesis. Smoking habits should be taken in account in clinical practice and in research concerning CC.

Abstract
Human papillomavirus (HPV) infections with oncogenic types account for approximately 500,000 deaths per year worldwide, predominantly in underdeveloped countries. The major cause of death is cervical cancer in women, but some additional cancers of the head and neck and anogenital sites also have an HPV etiology. Current virus-like particle-based vaccines are in clinical trials, and show very strong, long-lasting protection against vaccine-matched HPV types. These vaccines currently contain virus-like particles for the HPV types 6, 11, 16 and 18 (Gardasil®) and HPV16 and -18 (Cervarix®). Although type-specific neutralizing antibodies develop from immunizations with these virus-like particle vaccines, promising evidence for cross-protection against related but nonvaccine HPV types is emerging. Strategies to increase cross-protection to cover all oncogenic HPV types (currently approximately 20 types) are underway. These strategies include increasing the number of HPV types in the virus-like particle vaccine, and to the development of second-generation HPV vaccines that include the minor coat protein.

Abstract
Strong epidemiologic and molecular data now support the conclusion that human papillomavirus (HPV) infection is responsible for a distinct form of head and neck squamous cell carcinoma (HNSCC), independent from the traditional risk factors of tobacco and alcohol use. Patients with HPV-positive HNSCC have a different clinical presentation and better clinical outcomes than those with HPV-negative HNSCC. A diagnosis of HPV-positive HNSCC is associated not only with therapeutic relevance, but also has important implications for future prevention and screening strategies.

Abstract
The present study assessed, in cervical carcinoma, expression levels of seven immune response genes and sought correlation to response to treatment. The expression levels of CD28, CTLA4, ICOS, ICOSL, CD80 and CD86 and granzyme B genes were assessed by real-time RT-PCR in pre-treatment tumor fragments. During the six-month follow-up after treatment, 8 patients presented tumor and 10 survived free of tumor. The only gene whose expression levels were higher in patients with poor outcome (p = 0.03) was granzyme B. Further evaluation, in adequately powered prospective studies is warranted to confirm the data and to translate this observation to the clinical setting.

Abstract
Anogenital warts are a common clinical manifestation of genital infection with human papillomavirus type 6b (HPV-6b). Accumulating data indicate that an effective cellular immune response is required for the control of HPV infections. However, in a minority of patients there is a high rate of recurrence of wart lesions. We report the characterization of both local and systemic HPV-specific cellular immune responses in three patients with a history of recurrent genital warts. Although the patients had chronic recurrent wart lesions, we have shown that each had both detectable intralesional and peripheral HPV-specific T lymphocytes. Interestingly, the lesion-infiltrating T cells were specific for only one HPV antigen, focusing on only a few epitopes. Conversely, the T cells derived from peripheral blood recognized a broader range of HPV antigens. The characteristics of the HPV-specific cellular immunity that we have shown in these patients may be indicative of a failure to mount an effective response against the virus. This would be consistent with the chronic nature of the disease in these specific individuals. These observations could be relevant to the design and immunomonitoring of immunotherapeutic vaccines for persistent HPV infections.

Abstract
This study investigates human papillomavirus (HPV) infection in the oral cavities of 88 Australian renal transplant recipients and 88 immunocompetent controls. Oral cavities were examined for lesions and brushings collected for HPV analysis by consensus PCR. No warts were identified; HPV DNA was detected in 18% of transplant versus 1% control samples (P<0.001). Cutaneous HPVs predominated. One patient had HPV16 in samples taken four years apart without evidence of associated lesions or malignancy. Transplant recipients were more likely than controls to have current cutaneous warts (P<0.001), fewer sexual partners (P=0.001), and to have never consumed alcohol (P=0.01). Among the transplant group, the risk of an HPV-positive sample was higher among older patients (P=0.05), and those with past cutaneous warts (P=0.04). This study extends previous surveys by encompassing overt and asymptomatic infection, a broad spectrum of cutaneous and genital HPVs, and by providing new data on risk factors for oral HPV infection.

Abstract
Carcinoma of the cervix is causally related to infection with the human papillomavirus (HPV), and T cells play a pivotal role in the immune response of the host to rid itself of HPV infection. Therefore, we assessed the T-cell function of women with HPV-related cervical neoplasia against a superantigen, Staphylococcus enterotoxin B (SEB). Each woman provided a cervical brush specimen for HPV DNA testing and Papanicolaou (Pap) smears for the staging of cervical lesions. They also provided a blood specimen for determination of the ability of CD4(+) T and CD8(+) T cells to synthesize Th1 (interleukin-2 [IL-2], gamma interferon [IFN-gamma], and tumor necrosis factor alpha [TNF-alpha]) and Th2 (IL-10) cytokines in response to activation with SEB. Compared with control subjects with self-attested negative Pap smears, women with high-grade squamous intraepithelial lesions (HSIL) had significantly lower percentages of activated CD4(+) T cells that produced IL-2 (P = 0.045), IFN-gamma (P = 0.040), and TNF-alpha (P = 0.015) and a significantly lower percentage of activated CD8(+) T cells that produced IL-2 (P < 0.01). These data indicate that women with HPV-related cervical HSIL show a decrease in Th1 cytokine production by activated CD4(+) T cells and suggested that compromised T-helper functions may negatively impact the function of cytotoxic CD8(+) T cells.

Abstract
BACKGROUND In sub-Saharan Africa, cervical cancer is the leading cancer among women. The causative role of different human papillomavirus (HPV) types in cervical cancer is established, but the distribution of HPV types within this region is largely unknown. GOAL The goal was to study the distribution of HPV among family planning clinic attendees in Nairobi, Kenya. STUDY DESIGN This was a cross-sectional study of persons attending a family planning center in Nairobi, Kenya. RESULTS HPV data of 429 women were analyzed; 7.0% had low-grade intraepithelial lesions, 6.8% had high-grade intraepithelial lesions, and 0.23% had invasive cancer. One hundred ninety samples (44.3%) were HPV-positive (28.4% were positive for multiple types). The most common HPV types were HPV 52 (17.9% of positive samples), HPV 16 (14.7%), HPV 35 (11.6%), and HPV 66 (9.0%). The risk of high-grade squamous intraepithelial lesions (HSIL) was 88.5 times higher (95% CI, 8.5-1.4 x 10 ) in HPV 16-positive women than in HPV-negative women. Relative risks were 54.3 (95% CI, 4.0-1.4 x 10 ) for HPV 35, 49.2 (95% CI, 3.6-9.5 x 10 ) for HPV 52, and 21.7 (95% CI, 0.0-1.9 x 10 ) for HPV 18. The prevalence of HSIL was not increased in association with HIV-positivity, yet HIV-1 was significantly associated with high-risk HPV types ( P< 0.00001). CONCLUSION The pattern of HPV distribution in this population was different from that in other regions in the world, which has important consequences for HPV vaccine development.

Abstract
We are developing immunization strategies against cervical carcinoma and premalignant disease, based on the use of recombinant Semliki Forest virus (SFV) encoding the oncoproteins E6 and E7 from high-risk human papilloma viruses (HPV). Thus far, protein-based, as well as genetic immunization studies have demonstrated low to moderate cellular immune responses against E6 and E7. To improve these responses, we modified the structure and expression level of the E6 and E7 proteins produced by the SFV vector. Specifically, a construct was generated encoding a fusion protein of E6 and E7, while furthermore a translational enhancer was included (enhE6,7). Infection of cells with recombinant SFV-enhE6,7 resulted in the production of large amounts of the E6,7 fusion protein. The fusion protein was more stable than either one of the separate proteins. Immunization of mice with SFV-enhE6,7 resulted in strong, long-lasting HPV-specific cytotoxic T lymphocyte responses. Tumor challenge experiments in mice demonstrated that immunization with SFV-enhE6,7 resulted in prevention of tumor outgrowth and subsequent protection against tumor re-challenge.

Abstract
We evaluated antibody, cytokine (IFN-gamma, IL-5, TNF-alpha), and cytotoxic T lymphocyte (CTL) responses in chimpanzees immunized with monovalent or quadrivalent (HPV-6, -11, -16, -18) L1 virus-like particle (VLP) vaccines administered i.m. on aluminum hydroxyphosphate (alum) at weeks 0, 8 and 24. Maximum serum antibody titers to type-specific, neutralizing, conformational epitopes on HPV-11 or -16 L1 VLPs were detected by radioimmunoassay (RIA) four weeks after the second and third immunizations. HPV-11 and -16 neutralizing antibodies were also detected at similar time points with an Human papillomaviruses (HPV) neutralization assay using pseudovirions. Depending on the VLP type used for immunization, HPV type-specific cytokine responses were most frequently seen four weeks after the second or third immunizations and between weeks 44-52. Transient HPV-16 L1-specific CTL activity was observed only between weeks 16-24 in 3 of 22 (13.6%) chimpanzees immunized with HPV-16 L1 VLPs. These findings provide evidence that immunization with multivalent L1 VLPs on alum can evoke both neutralizing antibodies and Th1 and Th2 cytokine responses to several HPV types; however, induction of CTLs is infrequent.

Abstract
CONTEXT AIDS is one of the most important risk factors for progression and recurrence of anogenital condyloma. In a previous work, we observed that patients with warts and high-grade AIN (HAIN) had recurrences more frequently than did patients with warts without AIN. The mechanisms of this increased incidence of high-grade lesions in AIDS are not known. OBJECTIVE We studied the expression of the proliferative marker Ki-67 by immunohistochemical methods, in specimens of anal condyloma from HIV+ patients to clarify whether its expression can be associated to the grade of AIN. DESIGN A retrospective study of histological specimens. SETTING University referral unit. SAMPLE 34 patients were divided into two groups: (1) condylomas with low grade AIN (LAIN), with 25 patients; and (2) condylomas with HAIN, with 9 patients. In this latter group we examined two areas: 2A (HAIN area) and 2B (LAIN area). MAIN MEASUREMENTS The immunohistochemical reaction for Ki-67 was done on histological sections. Slices were lightly stained with hematoxylin, to help us in Ki-67 positive cell counting. The percentage of Ki-67 marked nuclei was calculated. We applied one-way variance analysis for statistics. RESULTS The mean number of Ki-67 positive cells in group 1 was 19.68 +/- 10.99; in group 2 (area A) it was 46.73 +/- 10.409; and in area B it was 36.43 +/- 14.731. There were statistical differences between groups 1 and 2A and between groups 1 and 2B. Ki-67 positive cells predominated in the lower layer in LAIN. Positive Ki-67 cells were found in all layers in group 2A, and in group 2B they predominated in the two lower or in all layers of the epithelium. CONCLUSIONS Our results suggest that LAIN areas (using routine staining techniques) in HAIN can have a biological behavior more similar to HAIN.

Abstract
BACKGROUND Recent studies have reported an increased incidence of squamous intraepithelial lesions in women infected with the human immunodeficiency virus (HIV). However, to the authors' knowledge there are scarce data regarding the relation between the CD4 T-lymphocyte count (CD4+), HIV viral load, and the development of cervical dysplasia as evidenced by cervicovaginal cytology. The objective of the current study was to examine the association between cervicovaginal smears (with and without squamous lesions) from HIV-infected women and their CD4+ counts and HIV viral load. METHODS Two hundred ninety-six cervicovaginal smears from 108 HIV-infected women were reviewed and classified according to the Bethesda system. Abnormal cytologies (n = 74) were followed by colposcopy and/or biopsy. CD4+ counts and HIV viral loads were available at the time of the cytologic evaluation. Statistical analysis was performed using the Student t test and the Mann-Whitney U test. RESULTS The control group (n = 222) had significantly higher CD4+ counts (378 vs. 246 cells/microL; P < 0.001) compared with the group with cervical lesions. There was no apparent difference between the CD4+ counts from women with low grade lesions and those from women with high grade lesions. The HIV viral load was significantly higher in patients with cytologic abnormalities than in those with negative Papanicolaou smears (P = 0.006). CONCLUSIONS The degree of immunosuppression may contribute to the development of intraepithelial lesions in HIV-positive women, but once the lesion is established disease progression may not be affected by the CD4+ counts.

Abstract
PURPOSE The incidence of anogenital squamous-cell carcinoma was observed to have increased since the beginning of the human immunodeficiency virus infection epidemic among male homosexuals, both with acquired immunodeficiency syndrome and without acquired immunodeficiency syndrome. It seems that immunosuppression is the most important risk factor for the progression of anogenital lesions, recurrences of anal condyloma, and development of anal carcinoma, in particular in acquired immunodeficiency syndrome. High-grade anal intraepithelial neoplasia was predominantly observed in the human immunodeficiency virus-positive men. We have also observed a high rate of recurrences of anal lesions in cases of high-grade anal intraepithelial neoplasia. However, there are many cases of recurrences of low-grade anal intraepithelial neoplasia that cannot be predicted by routine histologic studies. By using immunohistochemical methods, we studied the expression of Ki-67 in epithelial cells of low-grade anal intraepithelial neoplasia of patients with acquired immunodeficiency syndrome to try to predict recurrence of these lesions. METHODS Anal biopsies of 38 patients were studied retrospectively. Of these patients, 14 had no recurrences (Group 1), and 24 patients had recurrence of the anal lesions before one year of follow-up (Group 2). RESULTS The median percentage of Ki-67-positive cells in Group 1 was 6.3 +/- 7.03 and in Group 2 was 24.1 +/- 16.72. The difference between Groups 1 and 2 was statistically significant (P < 0.001). CONCLUSIONS Our results showed a high correlation between the percentage of Ki-67-positive cells and recurrences. We concluded that Ki-67 counting in low-grade anal intraepithelial neoplasia can aid in predicting recurrences and therefore aid in the follow-up of these patients.

Abstract
Human papillomavirus (HPV) infections are known to play an important role in the pathogenesis of cervical neoplasia. Considering the morbidity and mortality of cervical cancer, infection with HPV can be regarded as a worldwide problem, especially in developing countries. Currently, many studies focus on the development of both prophylactic and therapeutic HPV vaccines. Crucial for these vaccination protocols to be successful is that they will result in a long-lasting ability to generate an immune response that will eliminate the virus. HPV transmission and subsequent infection is a local event in the lower female genital tract and therefore the efficacy of vaccines against this locally transmitted infection can be best assessed by parameters of local immunity. In this review we describe both the epidemiology of HPV-related cervical neoplasia and the general aspects of mucosal immunity in the female genital tract while focusing on the local humoral immunity in HPV-related cervical neoplasia.

Abstract
Infection of genital epithelial cells with human papillomavirus (HPV) types 16 and 18 is closely associated with the development of cervical carcinoma. The transforming potential of these high-risk HPVs depends on the expression of the E6 and E7 early viral gene products. Since the expression of E6 and E7 is selectively maintained in premalignant and malignant cervical lesions these proteins are attractive candidates for immunotherapeutic and prophylactic strategies. This report describes the construction, characterization and the in vivo immunotherapeutic potential of recombinant Semliki Forest virus (SFV) expressing the HPV16 E6 and E7 proteins (SFV-E6E7). Western blot analysis and immunofluorescence staining demonstrated expression of E6 and E7 in BHK cells infected with SFV-E6E7. Immunization of mice with SFV-E6E7 resulted in an efficient in vivo priming of HPV-specific CTL activity. The induced CTL lysed murine tumor cells transformed with the HPV16 genome and EL4 cells loaded with an immunodominant class I-binding HPV E7 peptide. CTLs could reproducibly be induced by immunization with three injections of as few as 10(5) infectious units of SFV-E6E7. Protection from tumor challenge was studied using the tumor cell line TC-1. Immunization with 5 x 10(6) SFV-E6E7 particles protected 40% of the mice from tumor challenge. These results indicate that E6E7 expression by the efficient and safe recombinant SFV system represents a promising strategy for immunotherapy or immunoprophylaxis of cervical carcinoma.

Abstract
OBJECTIVE To monitor the presence and persistence of high risk (HR) human papillomavirus (HPV) in cervical brushings from HIV infected women. METHODS Prospective observational cohort study of HIV infected women. Women were enrolled from the cohort of 164 HIV infected women who attend the colposcopy clinic at the Edinburgh Regional Infectious Diseases Unit. A single cervical brush scrape was obtained from 39 women and two or more samples from 63 women who attended regularly at approximately 6 monthly intervals. HPV typing was carried out using a commercial hybrid capture assay (HCA). Details of antiretroviral therapy, cytological assessment, and histological evaluation were made available and the interrelation with HR-HPV detection analysed. RESULTS Abnormal cervical cytology, particularly of low grade, was common in these HIV infected women. HR-HPV types were detected in 25% of the women with normal cytology, while over 80% of those with abnormal cytology of any grade were HR-HPV positive. Persistent HR-HPV, as defined by two or more consecutive HPV positive results, was common and found in 27/63 women from whom multiple samples were obtained. HR-HPV was detected at high levels whether or not patients were receiving antiretroviral therapy. Profound immunosuppression was not necessarily associated with progression of cervical disease and no cases of invasive cervical disease were seen. CONCLUSION While mild dyskaryosis (low grade squamous intraepithelial lesion (LSIL)) and persistence of HR-HPV are common in HIV infected women in Edinburgh, regular cytological and colposcopic evaluation with appropriate intervention and treatment appears to limit the progression of cervical disease.

Abstract
Kaposi's sarcoma (KS) is the most prevalent AIDS-associated tumour, occurring in 20-30% of HIV-1-infected individuals in the early 1980s. The introduction of highly active antiretroviral therapy (HAART) has dramatically reduced the incidence of the disease and might therefore support the concept of 'opportunistic malignancies' requiring immune impairments to occur. The relationship between the immune system and the epidemiology of this virus-induced tumour is of importance in order to identify new therapeutic approaches for treating or preventing its occurrence. As a model of impaired angiogenesis, therapeutic options for treating AIDS patients with KS should therefore target cell division, anti-angiogenic processes, immune modulators, cytokines and potentially antiviral drugs.

Abstract
Three major neoplasms are associated with AIDS definition in the course of HIV infection due to their increased incidence. The relationship between the immune system and the epidemiology of these virus-induced tumors is of importance in order to identify new therapeutic approaches for treating or preventing these neoplasms. Major improvements in the understanding of the pathogenesis have already been performed. The impact of highly active antiretroviral therapy (HAART) on their incidence likely confirms the concept of 'opportunistic malignancies'. Other neoplasms are likely more prevalent in HIV-infected individuals, but their relative importance requires further prospective case-control cohort studies.

Abstract
We undertook a prospective study of cytology and concurrent colposcopically directed biopsies of both Human Immunodeficiencey Virus seronegative (HIV-) and seropositive (HIV +) women at high risk for cervical intraepithelial neoplasia (CIN) to determine the accuracy of Pap smears in this population. Women were recruited from a sexually transmitted disease clinic and a women's prison in eastern Massachusetts. All were interviewed, blood was tested for HIV with CD4 counts done in 101 of the 102 HIV + women, and all received a pelvic exam that included a conventional Pap smear, a Thinprep test, and colposcopy with directed biopsies and endocervical curettage. A total of 184 women volunteered. 82 were HIV- and 102 were HIV+. The prevalence of CIN in HIV+ women was 37%, more than twice the 17% prevalence of CIN in HIV-women (P = 0.002). When Atypical Squamous Cells of Undetermined Significance (ASCUS) findings were included with "negative" cytology, the conventional Pap smear false negative rates for HIV- and HIV+ women were 21% and 37%, respectively. When ASCUS was included with "positive" cytology, the false negative rates dropped to 14.3% for HIV- women and 10.5% for HIV+ women. We conclude that ASCUS diagnoses comprised the majority of false negatives in HIV+ women.

Abstract
Among HIV-positive women, infection with multiple human papillomavirus (HPV) types is known to be more frequent and persistent, as well as a greater prevalence of high-grade genital lesions. This study aims to characterize, for the first time in Brazil, HPV presence and types among HIV-positive women of a high-risk population for genital intraepithelial neoplasia (GIN) development. A non-anonymous, voluntary, cross-sectional epidemiological survey was conducted, from June 1996 to April 1997, among 141 HIV-positive women followed at the Center of Reference in AIDS (CRAIDS). They were submitted to gynaecological examination, cytological screening and biopsies whenever necessary, for GIN and HPV DNA detection through polymerase chain reaction (PCR) technique. Positive HPV DNA were found in 80.8% patients. Two or more HPV types were detected in 45% of the samples. The most frequent HPV types detected were 16, 18 (30.5%); 61, 53 (24.4%), and non-identified types (18.7%). According to the oncogenic potential, 34.8% were considered of high-risk types. Among these HIV-positive patients, a great variety of HPV types, including high-risk types, was found in anogenital environment, as well as among young women, a great prevalence of high-grade genital lesions. Thus, it should strengthen the need for a periodical careful gynaecological examination among those women.

Abstract
OBJECTIVE The aim of this study was to investigate whether coinfection with HIV affects the synthesis of Th1 and Th2 cytokines by peripheral blood T cells of women infected with human papillomavirus (HPV). METHODS Cervical swabs and peripheral blood were obtained from women referred for colposcopy. HPV DNA by Digene's hybrid capture assay, HIV RNA by Roche's Amplicor assay, and cytokine synthesis of T-cell subsets by flow cytometry were assessed. HPV-associated cervical and HIV-associated immune deficiency diseases were staged using the Bethesda System and the Centers for Disease Control criteria, respectively. RESULTS Patients with HIV and/or HPV infections had lower percentages of IL-2(+) and higher percentages of IL-10(+) T cells than healthy women. Furthermore, women with both virus infections (HIV(+)/HPV(+)) had significantly fewer IL-2(+) CD4(+), IFN-gamma(+) CD4(+), and TNF-alpha(+) CD4(+) T cells than women with HPV infection alone (HPV(+)). Whereas HIV(+) and healthy women had similar numbers of IFN-gamma(+) CD8(+) T cells, HPV(+) women had significantly fewer IFN-gamma(+) CD8(+) T cells than healthy women. CONCLUSION HIV infection adversely affects the synthesis of Th1 cytokines by CD4(+), but not IFN-gamma synthesis by CD8(+) T cells of women with active HPV infection. The increase in IFNgamma(+) CD8(+) T cells, a phenotype consistent with cytotoxic T lymphocytes, may account for the stable HIV disease of the women studied. However, the increase in IFN-gamma(+) CD8(+) T cells is less likely to be HPV-specific as there was a higher incidence of HPV-related cervical SIL in HIV(+)/HPV(+) women compared with HPV(+) women.

Abstract
AIMS To evaluate the value of polymerase chain reaction-in situ hybridization (PCR-ISH) for the detection of human papillomaviruses (HPV) in paraffin sections of cervical biopsies fixed either in 10% formalin or in Bouin's solution. METHODS AND RESULTS We analysed 40 biopsies from Italian women infected with the human immunodeficiency virus type 1 (HIV 1). In-situ hybridization techniques were performed with commercial biotinylated probes. The PCR-ISH was carried out by the 'hot start modification'. Cervical intraepithelial neoplasia (CIN) was found in 23 of 40 patients (57. 5%); eight cases showed condylomatous features. Human papillomavirus was detected in 42.5% by ISH and in 65% by PCR-ISH. Sixty-nine per cent of positive biopsies contained HPV 16, 18, 31 and 33. HPV 6 and 11 were found only in condylomata acuminata samples. CONCLUSIONS The results point to a high incidence of HPV infection as well as of CIN in HIV-positive patients. Human papillomavirus type 16 appears to be most frequently associated with CIN. Polymerase chain reaction-ISH is more sensitive than ISH in the detection and typing of HPV DNA both in clinical and in 'latent' infections. The two techniques yielded the same results with either formalin- or Bouin's-fixed material.

Abstract
OBJECTIVE To explore whether HIV serostatus (HIV-1, HIV-2, and dual (HIV-D) reactivity) and CD4 cell count affect human papillomavirus (HPV) in two groups of women from Côte d'Ivoire. METHODS We conducted a cross sectional study of two groups of women. One group had low numbers of lifetime sex partners (maternal women, n = 258) and were enrolled based on HIV serostatus. The other group had high numbers of sex partners (female sex workers, n = 278) and all consenting self identified sex workers were admitted to this study. We collected epidemiological and clinical data, and cervicovaginal lavage for HPV testing. RESULTS The groups had different distributions of HIV seroreactivity, but the rates of HPV DNA detection were similar. Most of the HPV DNAs detected in both groups were high risk types. A strong association of high risk HPV DNA and HIV-1 seropositivity was found in both maternal women (adjusted odds ratio (OR) 7.5 (95% CI 3.2-17.4)) and in sex workers (OR 5.0 (2.1-12.0)). The maternal group also showed an association of high risk HPV DNA detection with HIV-2 (OR 3.7 (1.6-8.5)) and HIV-D (OR 12.7 (4.3-37.5)) that was not observed in the sex workers. In addition, the association of high risk HPV DNA with HIV-1 in the maternal group was independent of low CD4 cell count, while in the sex workers the association depended on CD4 cell counts < or = 500 x 10(6)/l. CONCLUSIONS We found that an association between HPV and HIV varied depending on the sexual behaviour and CD4 cell count of the population examined.

Abstract
OBJECTIVE The purpose of this study was to investigate whether subjective sleep quality is more strongly associated with immunocompetence than depression among women at risk for cervical cancer. METHODS Participants were 91 women referred for colposcopy because of abnormal results on a Pap smear. On the day of the procedure. participants completed the Center for Epidemiological Studies Depression Scale, two indices of subjective sleep quality (ie, satisfaction with sleep obtained and degree of sleep restfulness), and a health behaviors assessment questionnaire. Levels of peripheral blood lymphocyte subpopulations (helper T, cytotoxic/suppressor T, NK, and B cells) were also assessed at this time. Approximately 10 days later, the presence of depressive disorder was assessed using the Structured Clinical Interview for DSM-III-R. RESULTS Hierarchical regression analyses revealed that satisfaction with the amount of sleep obtained was significantly associated with the circulating number and percentage of helper T cells (T(H)/CD4+) and the percentage of cytotoxic/suppressor T cells (T(C)/CD8+), after controlling for confounder variables (ie, age, smoking status, and drug use). Depression was significantly associated only with the percentage of T(C) cells. Sleep satisfaction remained significantly associated with the number and percentage of T(H) cells and percentage of T(C) cells after controlling for the variance explained by depression. CONCLUSIONS Results of this study suggest that subjective sleep quality shares a significant and independent portion of the variance with immunity that is not accounted for by depression. Although the long-term impact of these immune alterations on disease progression needs to be directly explored, it may be important to systematically screen for and manage sleep disturbance in women at high risk for cervical cancer.

Abstract
BACKGROUND Cervical neoplasia occurs with increased frequency among women infected with HIV-1. OBJECTIVE To characterize prevalence of and risk factors for abnormal cervical cytology among women with HIV and to compare them to uninfected women. METHODS Baseline cervical cytology was obtained from 1713 women seropositive for HIV and 482 at-risk control women who were enrolled in the Women's Interagency HIV Study, a multicenter prospective cohort study conducted in six U.S. cities. Associations with sociodemographic, medical, and sexual variables were assessed by Fisher's exact test, Mantel extension test, and logistic regression analysis. RESULTS Cervical cytology was abnormal in 38.3% of HIV-infected women (atypical squamous cells of uncertain significance [ASCUS] 20.9%, low-grade squamous cells of uncertain significance [LSIL] 14.9%, high-grade squamous cells of uncertain significance [HSIL] 2.3%, cancer 0.2%) and 16.2% of HIV-uninfected women (ASCUS 12.7%, LSIL 2.3%, HSIL 1.2%, cancer 0.0%). Risk factors for any abnormal cytology in multivariate analysis included HIV infection, CD4 cell count, HIV RNA level, detection of human papillomavirus (HPV), a prior history of abnormal cytology, employment, and number of male sex partners within 6 months of enrollment. Prior abortion was associated with a decreased risk of cytologic abnormality. CONCLUSIONS Cervical cytologic abnormalities were frequent among women infected with HIV, although high-grade changes were found in only 2.5%. Factors linked to sexual and reproductive history, HPV infection, and HIV disease all influenced risk.

Abstract
The impact of sexually transmitted diseases (STDs) on the development of cervical intraepithelial neoplasia (CIN) has been increasingly recognized over the last 20 years. Much attention has been focused on human papillomavirus (HPV) and the potential for screening for certain HPV types alongside standard cervical cytology in the hope of identifying those females at particular risk of developing high grade CIN or invasive carcinoma. Some infections, for example herpes simplex virus (HSV), have been heavily investigated in the past as they were thought to be involved in the development of CIN but were subsequently discounted. Also discounted as causes of CIN are Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). These infections were found to be associated with higher rates of CIN in early studies but transpired to be markers for the presence of other infections and pathology and therefore not themselves directly responsible for cytological changes. The role of bacterial vaginosis (BV) is the focus of several current investigations, not only in the genesis of CIN but also in the development of other gynecological and obstetric conditions and complications. Evidence to implicate Trichomonas vaginalis (TV) in the genesis of CIN is conflicting, but there is some evidence that it may exert its influence in a similar way to that hypothesized for BV, ie via abnormal amines. It is well known that there is a high level of concordance of STDs whereby the presence of one infection greatly increases the likelihood of there being one or more others present. There may be a synergism between some infections with regard to the causation of CIN, although the evidence for this is putative. Presented here is an overview of current and previous research in the field of lower genital tract infection as it relates to the development of CIN.

Abstract
OBJECTIVES To identify risk factors for human papillomavirus (HPV) infection and squamous intraepithelial lesions (SIL) of the cervix, and to measure the impact of concurrent HIV-1 infection. METHODS Women were studied at a family planning clinic in Nairobi, Kenya. Demographic and historical information was obtained using a semi-structured questionnaire and specimens were collected for sexually transmitted diseases (STDs), HPV, cervical cytology, and HIV-1 testing. RESULTS HPV was detected in 87 of 513 women (17%), including 81 (93%) oncogenic types (16, 18, 31, 33 and others) and six (7%) non-oncogenic types (6 and 11). HIV-1 prevalence was 10%. HPV detection was associated with HIV-1 infection [adjusted odds ratio (aOR) 3.9, 95% confidence interval (CI), 2.0-7.7], sexual behavior indicators including the number of sex partners and inflammatory STDs, as well as the number of pregnancies (0 or 1 vs. > or = 3, aOR 0.4; 95% CI, 0.2-0.9). SIL was detected in 61 women (11.9%), including 28 (46%) with low-grade lesions (LSIL) and 33 (54%) with high-grade lesions (HSIL). HPV infection was strongly associated with HSIL (OR 14.9; 95% CI, 6.8-32.8). In a multivariate model predictors of HSIL included HIV-1 serpositivity (aOR 4.8; 95% CI, 1.8-12.4), the number of lifetime sex partners (0-1 vs. > or = 4; aOR 3.8; 95% CI, 1.1-13.5), and older age (< 26 vs. > 30; OR 3.9; 95% CI, 1.1-13.6). An analysis stratified by HIV-1 showed a stronger association between HPV and HSIL in HIV-1 negative women (OR 17.0; 95% CI, 6.4-46.3) then in HIV-1 positive women (OR 4.5; 95% CI, 0.8-27.4). CONCLUSION Our results indicate that HSIL and even invasive cancer are highly prevalent in this setting of women on reproductive age considered to be at low risk for STDs, suggesting that routine Pap smear screening may save lives.

Abstract
BACKGROUND AND OBJECTIVES Few comparisons of factors associated with sexually transmitted diseases (STDs) and HIV are available for representative samples of American women. GOAL OF THE STUDY To compare factors associated with STDs in a large sample of women infected with HIV and women not infected with HIV. STUDY DESIGN A cross-sectional analysis of STDs in 2,058 women seropositive (HIV+) for HIV and 567 women seronegative (HIV-) for HIV. RESULTS HIV + women were more likely than HIV- women to report previous STDs, with the exceptions of chlamydia and bacterial vaginosis. Both HIV status and CD4 lymphocyte count were associated with evidence of genital ulcerations, warts, and vaginal candidiasis (p <0.001 for all). HIV- women were more apt to report recent vaginal intercourse (p <0.001), a factor that was independently associated with the occurrence of bacterial and protozoan infections. CD4 lymphocyte depletion was the factor most closely associated with the expression of chronic viral infections. CONCLUSIONS In this North American cohort, HIV+ women were more likely than HIV- women to report previous genital tract infections and symptoms. However, the HIV+ women reported less recent sexual activity and few gonococcal or chlamydial infections.

Abstract
OBJECTIVE To assess the association of squamous intraepithelial lesions (SIL) on cervicovaginal Papanicolaou (Pap) smear among women infected with HIV-1 and their pregnancy status, and historical and clinical factors. METHODS Study enrollment Pap smears of 452 pregnant and 126 nonpregnant HIV-infected women had cytologic evaluation. The rates of SIL were compared with pregnancy status, immunosuppression, presence of sexually transmitted diseases (STDs) and demographic features. RESULTS Rates of low grade SIL were similar for pregnant and nonpregnant HIV-1-infected women (17% and 23.8%, respectively; p = .09). Of them, 12 women, 9 pregnant and 3 nonpregnant, had high grade SIL. None had invasive cervical cancer. Low CD4 percentage (odds ratio, [OR] = 3.8; 95% confidence interval [CI], 2.0-7.3) and inflammation (OR = 2.8; 95% CI, 1.8-4.3) were associated with SIL. An association between herpes simplex and SIL (OR = 3.3; 95% CI, 1.1-9.5) was less certain due to clinical diagnosis and low prevalence of herpes simplex (17 of 456 women). CONCLUSIONS Pap smears for a cohort of HIV-infected pregnant and nonpregnant women revealed a high prevalence of LGSIL but a low prevalence of HGSIL and no cases of cervical cancer. Although pregnancy may not affect the rate of Pap smear abnormalities, SIL is associated with immunosuppression, cervical inflammation, and herpes simplex. Closer surveillance of HIV-1-infected women with these risk factors may be warranted.

Abstract
UNLABELLED Human immunodeficiency virus (HIV) and human papillomavirus (HPV) are both sexually transmitted viruses with many risk factors in common. Studies have found that HIV-seropositive women are at least five times as likely to be infected with HPV as seronegative controls. In immunocompromised HIV-seropositive women, the risk of cervical intraepithelial neoplasia (CIN) is almost as high as in women with squamous intraepithelial lesions on their Pap smear. Some studies have shown the false-negative rate of cervical cytology in HIV-seropositive women to be very high, although others have shown it to be comparable with the rate in seronegative controls. However, given the prevalence of CIN in this population, even a "normal" false-negative rate may result in many missed CIN lesions. Among HIV-seropositive women and especially among those who are immunocompromised, CIN is more likely to progress and recur after treatment. Recurrence rates may reach 87 percent 36 months after treatment in markedly immunosuppressed women. Cryotherapy is especially ineffective in these patients. Vulvar condyloma and vulvar intraepithelial neoplasia (VIN) are much more prevalent in HIV-seropositive women and especially in those who are markedly immunosuppressed or who have been immunosuppressed for a prolonged period of time. It is recommended that all HIV-seropositive women undergo periodic evaluation at intervals no less than every 6 months. Immunocompromised women should be followed with cytology and colposcopy of the cervix and vulva, although those with normal immune systems may be followed with cytology alone. Because the rates of recurrence and progression are so high after treatment of these women, they should be followed with colposcopy and cytology every 6 months. New approaches to treatment need to be explored in this population. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader will understand the association between the immune suppression of HIV and HPV-related diseases, be familiar with the treatment options for the HIV-seropositive woman with cervical intraepithelial neoplasia (CIN), understand the natural history of CIN in the patient with HIV-seropositivity, and become aware of the appropriate surveillance of the HIV-seropositive woman treated for CIN.

Abstract
OBJECTIVE To study the effect of tissue specific human papillomavirus (HPV) expression and its effect on local immunity in condylomas from HIV positive individuals. METHODS Biopsy specimens of eight penile and eight perianal condylomas from HIV seropositive individuals were analysed. Expression of viral genes (HIV-tat and HPV E7 and L1) was determined by RT-PCR. The status of local immunity also was determined by RT-PCR by measuring CD4, CD8, CD16, CD1a, HLA-DR, and HLA-B7 mRNA levels in the tissues. Differentiation was determined by measuring involucrin, keratinocyte transglutaminase, as well as cytokeratins 10, 16, and 17. Proliferation markers such as PCNA and c-myc were also determined. RESULTS The transcription pattern of HPV in perianal condylomas, which preferentially expressed the early (E7) gene, was different from that of penile condylomas, which primarily expressed the late (L1) gene. This transcription pattern is in good correlation with the keratinisation and differentiation patterns of the two epithelia: perianal biopsies preferentially expressed K16 and K17 while penile warts mainly expressed K10, markers of parakeratotic and orthokeratotic epithelia, respectively. Perianal biopsies also showed a higher degree of proliferation (PCNA and c-myc). Interestingly, transcription of HIV-tat was also higher in perianal than in penile biopsies. A high degree of local immunodeficiency was observed in perianal biopsies--that is, levels of CD4, CD16, and CD1a mRNAs were significantly lower. A negative correlation between CD1a (Langerhans cells) levels and HPV E7 levels was established. HPV E7 levels positively correlated with HIV-tat levels. Perianal tissues demonstrated more CD1a depression and tat associated HPV upregulation. CONCLUSION HIV influences the expression of HPV genes resulting in local immunosuppression that might lead to an inappropriate immune surveillance of viral infection. Also, tissue type is an important factor in controlling viral transcription in a differentiation dependent manner. These findings may explain the higher rate of dysplasia and neoplasia in the perianal area.

Abstract
In the US over one million persons are currently infected with the HIV, over half a million have had AIDS, and over 300,000 have died from AIDS. Worldwide, it is estimated that more than 17 million people are currently infected with HIV, and over 1,200,000 cases of AIDS have been reported to the World Health Organization. By some estimates, up to 40% of patients with AIDS will ultimately develop some form of cancer. Non-Hodgkin's lymphoma, Kaposi's sarcoma and invasive cervical cancer have a higher incidence in persons with HIV infection and all three are AIDS-defining illnesses. In addition, several reports suggest that a number of other malignancies may occur at an increased incidence in persons with HIV infection, including squamous-cell carcinoma of the head, neck and anus, plasmacytoma, melanoma, small-cell lung cancer, basal-cell cancer, and germ-cell tumours. Clinicians should become familiar with HIV-related malignancies as their incidence is expected to further increase as more effective therapies for HIV and associated opportunistic infections allow patients to live longer in an advanced state of immunodeficiency. In the current article, we will review the clinical and therapeutic aspects of the most common AIDS-related malignancies including non-Hodgkin's and Hodgkin's lymphomas, Kaposi's sarcoma and anogenital epithelial neoplasias.

Abstract
OBJECTIVE To review the literature regarding the molecular events which occur in the development of uterine cervical cancer, with particular reference to human papillomavirus (HPV) infection. METHODOLOGY Bibliographic searches of Medline and the ISI citation databases using appropriate keywords, including the following: papillomavirus, cervix, pathology, cyclin, chromosome, heterozygosity, telomerase, smoking, hormones, HLA, immune response, HIV, HSV, EBV. CONCLUSIONS It has become clear that most cervical neoplasia, whether intraepithelial or invasive, is attributable in part to HPV infection. However, HPV infection alone is not sufficient, and, in a small proportion of cases, may not be necessary for malignant transformation. There is increasing evidence that HPV gene products interfere with cell cycle control leading to secondary accumulation of small and large scale genetic abnormalities. This may explain the association of viral persistence with lesion progression but, in many patients, secondary factors, such as smoking and immune response, are clearly important. However, the mechanisms involved in the interaction between HPV and host factors are poorly understood.

Abstract
OBJECTIVES The objective was to evaluate the sensitivity and specificity of cervical cytology in women infected with the human immunodeficiency virus (HIV), risk factors for abnormal cytology in HIV-infected and uninfected women, and risk factors for histologic diagnosis of cervical intraepithelial neoplasia (CIN) in HIV-infected women. METHODS Methods included a cross-sectional analysis of cervical cytology, colposcopic impression, and histology in 248 HIV-infected women and multivariate analyses of risk factors for abnormal cytology in 253 HIV-infected and 220 uninfected women and risk factors for CIN in 186 HIV-infected women. RESULTS The sensitivity and specificity of cytology for all CIN grades were 0.60 and 0.80 and, for high-grade CIN, 0.83 and 0.74. The prevalence of abnormal cytology was 32.9% in HIV-infected and 7.6% in HIV-negative women. Independent risk factors for abnormal cytology were immunodeficiency [odds ratio (OR) 8-17, P < 0.001] and human papillomavirus (HPV) infection (OR = 5, P < 0.001). The prevalence of CIN on histology was 32% in HIV-infected women, and the only independent risk factor for CIN was oncogenic HPV type (OR = 5, P = 0.005). CONCLUSION Given the high prevalence of abnormal cytology and CIN in HIV-infected women, cytologic screening has significant limitations. Both immunodeficiency and type of HPV infection are important risk factors.

Abstract
Overdiagnosis of HPV infection in cervical biopsies results in increased health care costs and unnecessary surgical procedures. Stringent criteria for histological diagnosis of koilocytosis were evaluated, using molecular detection of HPV DNA (polymerase chain reaction and Southern blot hybridization) as gold standard. Colposcopic biopsy specimens from 511 patients were studied, including 76 with referral diagnoses of negative cervix and 241 with CIN 1 or koilocytosis. Referral diagnoses for low-grade lesions failed to distinguish between HPV-infected and uninfected patients. False-positive rate for prediction of HPV infection was 74.8%. Biopsy specimens reevaluated using stringent diagnostic criteria showed increasing prevalence of HPV infection among patients whose biopsy specimens showed negative (43.7%), minimal (52.4%), or definite (69.5%) features of koilocytosis (P = .001). Similarly, subjects infected with high viral load or oncogenic HPV infection were more likely to be identified (P = .004 and .04, respectively). Despite increased predictive value of stringent diagnostic criteria, significant number of patients diagnosed as having CIN 1/koilocytosis (34.0%) did not in fact have HPV infection. Because most low-grade lesions spontaneously regress, patients with histological diagnosis of CIN 1 or HPV infection should be observed for a period of several months before definitive ablative treatment is undertaken.

Abstract
We assessed the association between different HPV genotypes, HIV infection, and cervical squamous intra-epithelial lesions (SIL) in 236 women with known HIV serostatus enrolled in a longitudinal multicentric study in Italy. Of these women, 135 were HIV-infected, and were not markedly different from HIV-negative women with regard to demographic characteristics, sexual practices, smoking, or intravenous drug use. We obtained 232 cervical smears suitable for cytological examination and HPV-genotype analysis (134 from HIV-positive women and 98 from HIV-negative women). For 86 HIV-positive and 89 HIV-negative women, the smears appeared normal at cytomorphological analysis. Cytological dysplasia of varying degrees was detected in 48 smears from HIV-positive women and in 9 from HIV-negative women. HPV prevalence, assessed using polymerase-chain-reaction analysis, did not significantly differ between HIV-positive and HIV-negative women. The prevalence of HPV-associated SIL was much greater among HIV-infected women. The most frequently detected genotypes in both groups were HPV 16 and HPV 18. The prevalence of HPV 16 among HIV-positive women was similar to that for HIV-negative women; this was also true for HPV 18. However, in the HIV-positive group, most of these genotypes were associated with SIL. HIV-positive women showed a wider spectrum of genotypes, including non-oncogenic and rare types. An association between SIL and HIV infection was confirmed for all HPV genotype classes.

Abstract
The potential role of T cells in the control of human papillomavirus type 6 (HPV-6) infections is an appealing premise, but their actual role has been sparsely investigated. Since HPV-6 infections are confined to the epithelium, such an investigation should focus on the T cells present at the site of infection (i.e., the warts). Therefore, we isolated wart-infiltrating lymphocytes (WIL) from patients with clinically diagnosed anogenital warts. These WIL were characterized by their phenotype and their specificity for E7 and L1 proteins of HPV-6. The phenotype of WIL varied drastically from patient to patient, as determined by their expression of CD4, CD8, T-cell receptor alpha/beta chain (TCR alpha beta), and TCR gamma delta. Despite this heterogeneity in phenotype, HPV-6 E7 and/or L1-specific WIL, as determined by lymphoproliferation, could be isolated from more than 75% of the patients studied. Among all L1 peptides recognized by WIL, peptides 311-330 and 411-430 were the most consistently detected, with seven of nine patients for whom L1 peptide reactivity was observed responding to at least one of them. Moreover, the HPV-6 epitopic peptides recognized by WIL differed to some extent from those recognized by peripheral T cells.
