Incidence and clearance of cervical and anal high-risk human papillomavirus in kidney transplant recipients: Results from a Danish prospective clinical study. Am J Transplant 2024:S1600-6135(24)00200-4. [PMID: 38458364 DOI: 10.1016/j.ajt.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 02/28/2024] [Accepted: 03/04/2024] [Indexed: 03/10/2024]
Abstract
This study investigates the incidence and clearance of cervical and anal high-risk human papillomavirus (hrHPV) infection in kidney transplant recipients (KTRs) compared to immunocompetent controls. During 2016-2017, we enrolled 125 female KTRs and 125 female controls. Liquid-based cervical and anal cytology samples collected at enrollment and follow-up were tested for human papillomavirus (HPV) DNA using the CLART HPV2 test. All participants answered a questionnaire on lifestyle and sexual behavior at both examinations. KTRs had an increased age-adjusted risk of incident cervical hrHPV infection compared to controls (hazard ratio [HR] = 3.6, 95% CI = 1.2-11.2). Probability of cervical hrHPV clearance at 18 months was lower among KTRs (8.3%) than controls (66.7%). There was no statistically significant difference in anal hrHPV incidence between KTRs and controls (HR = 0.9, 95% CI = 0.4-2.0). Clearance of anal hrHPV was similar between KTRs and controls at 18 months. During the total follow-up, a lower anal hrHPV clearance, although not statistically significant, was observed among KTRs (HR = 0.3, 95% CI = 0.06-1.2). KTRs had higher incidence of cervical hrHPV and lower probability of clearance, especially of cervical hrHPV infections, than controls. Our findings support that KTRs are at increased risk of HPV infection and point to the need for targeted HPV prevention strategies, such as cervical cancer screening.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063531. [PMID: 35329222 PMCID: PMC8953826 DOI: 10.3390/ijerph19063531] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 03/08/2022] [Accepted: 03/14/2022] [Indexed: 12/16/2022]
Abstract
Immunocompromised women are at an increased risk of developing malignancies, especially those that are viral-induced, such as invasive cervical cancer caused by the human papillomavirus (HPV). The aim of the study was to describe gynecological follow-up of women undergoing chronic immunosuppressive therapy for various reasons (e.g., kidney/liver transplant, systemic lupus erythematosus), diagnosed with a high-risk HPV (hrHPV) infection based on a self-sampling test. Twenty-six hrHPV-positive women were invited to take part in a gynecological follow-up, including a visual assessment of the anogenital region, two-handed gynecological examination, and cervical cytology as well as a colposcopy and cervical biopsy when necessary. Four women declined taking part in the study. Over six years of observation, low-grade squamous intraepithelial lesions (LSIL) were detected at least once in 7/22 women (31.8%), and a cervical intraepithelial lesion 1 (CIN 1) histopathologic result was obtained five times in 3/22 women. No cases of high-grade squamous intraepithelial lesions, CIN 2/3, or invasive cervical cancers were observed. Loop electrosurgical excision procedure (LEEP) was performed in three patients. As immunocompromised women are prone to persistent hrHPV infections, they should be under strict gynecological supervision because only vigilant surveillance enables fast detection and treatment of early dysplasia and, therefore, provides a chance for the reduction of the cervical cancer burden.

Abstract
Objective Vaccine efficacy among previously exposed, but currently uninfected women, i.e., those who have serological evidence of a prior human papillomavirus (HPV) infection without corresponding detectable HPV DNA, remains incompletely defined. This meta-analysis assessed the serotype-specific efficacy of prophylactic HPV vaccination against HPV16/18 persistent infection (PI) and cervical intraepithelial neoplasia (CIN) among seropositive, DNA negative (SPDN) women enrolled to randomized controlled trials (RCTs) of HPV L1-based vaccines. Methods Searches were conducted on 08/16/20 on MEDLINE, Embase, Scopus and CENTRAL. RCTs of L1-based prophylactic bivalent or quadrivalent HPV vaccines, reporting serotype-specific clinical efficacy endpoints in the HPV16/18 seropositive, DNA-negative populations were included. Relative risks (RRs) of 6-month PI (6mPI), 12-month PI (12mPI), CIN1+ and CIN2+ were pooled using a random-effects model. Results A total of 1,727 citations were reviewed. 8 studies, with a total of 9,569 SPDN participants, met all eligibility criteria. The RR of 6mPI (RR=0.22; 95% confidence interval [CI]=0.08–0.61; p=0.018), 12mPI (RR=0.20; 95% CI=0.05–0.80; p=0.035), CIN1+ (RR=0.13; 95% CI=0.05–0.30; p=0.003) and CIN2+ (RR=0.15; 95% CI=0.04–0.59; p=0.022) was significantly reduced in the vaccinated compared to the unvaccinated group. Conclusion Our findings suggest high serotype-specific efficacy for HPV vaccination among cohorts of women with evidence of prior HPV16/18 infections, including 87% efficacy (95% CI=70%–95%; p=0.003) against HPV16/18 cervical dysplasia. HPV vaccination is highly effective among uninfected women, regardless of prior exposure history. Trial Registration PROSPERO Identifier: CRD42020206888

Incidence of cervical intraepithelial lesions and human papilloma virus infection in female renal transplant recipients. Transpl Infect Dis 2021; 23:e13622. [PMID: 33877726 DOI: 10.1111/tid.13622] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 03/03/2021] [Accepted: 04/05/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Female renal transplant recipients (RTR) are at high risk of human papillomavirus (HPV)-related anogenital premalignancies and cancer. The aim of this study was to estimate the incidence of cervical intraepithelial lesions (IL) and HPV infection, and their associated factors, in Mexican RTR. METHODS This is a prospective cohort study conducted between January 2011 and December 2017. Demographic, clinical, and gynecological data were collected using a previously designed questionnaire. Gynecological examination, cervical cytology, and detection of high- and low-risk HPV DNA were undertaken prior to and after the renal transplant (RT). Colposcopically guided biopsies were obtained from patients who presented high grade squamous intraepithelial lesions (HSIL) during the follow-up period. Diagnoses were established according to the Bethesda system. RESULTS Among 130 RTR, 62 were eligible for our study. The overall incidence of IL was 17.7% (95% CI, 8% to 27%), (11/62 patients), at 25.6 ± 10.7 months post-RT. Nine out of the eleven affected patients had low-grade squamous intraepithelial lesions (81.8%) and only two had HSIL (18.2%). The incidence of HPV infection, determined in a subgroup of 30 RTR, was 53.3% (95% CI, 35% to 71%), (16 out of 30 patients), at 18.3 ± 8.9 months post-RT. High-risk HPV genotypes were present in 62.5% of HPV positive cases (10/16). In 11 patients (36.6%), HPV infection was not associated to IL. CONCLUSIONS HPV infection and cervical IL are common in the early posttransplant period. Our findings support the need of screening for cervical cancer to detect precancerous changes in RTR and the need of strengthening the knowledge of medical personnel on this issue.

Human Papillomavirus (HPV) DNA Detection Using Self-Sampling Devices in Women Undergoing Long Term Immunosuppressive Therapy. Viruses 2020; 12:v12090962. [PMID: 32872666 PMCID: PMC7552011 DOI: 10.3390/v12090962] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 08/22/2020] [Accepted: 08/28/2020] [Indexed: 12/26/2022] Open
Abstract
Immunosuppression is a risk factor of persistent human papillomavirus (HPV) infections, which might lead to development of (pre)malignant lesions of the cervix and lower anogenital tract. Results of HPV DNA testing using cervicovaginal self-samples are comparable to those that are clinician-obtained and therefore might be used in cervical screening. The aim of this study was to assess the prevalence of high-risk HPV (hrHPV) infections, their risk factors and the genotypes distribution among women undergoing immunosuppressive therapy. Women undergoing immunosuppressive therapy for at least three months due to solid organ transplantation or autoimmune disorders were asked to self-collect samples for HPV testing using cervicovaginal brushes and complete questionnaires regarding cervical cancer risk factors. HPV DNA detection and genotyping were performed using Genotyping kit HPV GP version 2. hrHPV was detected in 26/90 (28.9%) specimens. Genotyping revealed a broad range of hrHPV, with type 16 being the most common genotype (11/26). The components of bivalent/quadrivalent or nonavalent vaccines cover all genotypes present in 4.4% and 17.8% women, respectively, and occur as a co-infection with other types in 12.2% and 23.3% of women, respectively. The only feature significantly associated with being hrHPV-positive was having at least two lifetime sexual partners. The high prevalence of hrHPV infections among immunosuppressed women emphasizes the need for regular cervical cancer screening with HPV DNA testing, which might be performed on self-collected specimen.

Incidence and Clearance of Anal High-risk Human Papillomavirus Infections and Their Determinants Over 5 Years Among Human Immunodeficiency Virus-negative Men Who Have Sex With Men. Clin Infect Dis 2020; 68:1556-1565. [PMID: 30169621 DOI: 10.1093/cid/ciy738] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Accepted: 08/29/2018] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND We aimed to assess the incidence and clearance of anal high-risk human papillomavirus (hrHPV) infections and determinants thereof among human immunodeficiency virus (HIV)-negative men who have sex with men (MSM) over a period of up to 5 years. METHODS From 2010 to 2015, HIV-negative MSM were followed every 6 months. Anal self-swabs were collected at inclusion and every 6 months thereafter, and were HPV genotyped using the SPF10-PCR DEIA/LiPA25-system-v1. Incidence rates (IRs) and clearance rates (CRs) of incident anal hrHPV infections were assessed by hrHPV type (types 16, 18, 31, 33, 45, 52, and 58). Determinants of transitions between uninfected and infected states were assessed by hrHPV type using a time-homogenous multi-state Markov model. RESULTS This study included 713 HIV-negative MSM, with a median age of 37 years (interquartile range [IQR] 31-43) and a median number of study visits of 6 (IQR 2-7). The IRs of anal infections had a median of 5.2 per 100 person-years (range: 2.2-7.9) across types, with HPV16 having the highest IR. The CRs of incident anal hrHPV infections had a median of 53.7 per 100 person-years (range: 33.4-65.3) across types, with HPV16 having the lowest CR. Having had over 100 lifetime sex partners was significantly associated with incident anal hrHPV infections in multivariable analyses. CONCLUSIONS The high incidence and low clearance rates of anal HPV16 infection, compared to other hrHPV types, is consistent with HPV16 being implicated in the large majority of anal cancer cases.

Abstract
OBJECTIVE To examine the incidence of lower genital tract dysplasia in women after solid organ transplantation, to evaluate risk factors associated with development of dysplasia, and to assess the timeline of disease development. METHODS This was a retrospective study of female patients who underwent solid organ transplantation at a large-volume tertiary care center between 2000 and 2015. Demographic and clinicopathologic factors were extracted from electronic medical records. Cumulative incidence of lower genital tract dysplasia was calculated, and univariate and multivariable logistic regression were performed to identify risk factors for the development of dysplasia. RESULTS Among 394 female solid organ transplant recipients, the median age was 41 years (interquartile range 29-53). Forty-seven (11.9%; 95% CI 8.8-15.9%) women developed lower genital tract dysplasia over a median follow-up of 7.8 years (interquartile range 4.6-12.9). Thirty-eight (9.6%) developed cervical intraepithelial neoplasia (CIN), with 14 (3.6%) diagnosed with CIN 2 or worse (one was cervical carcinoma). Nineteen (4.8%) developed noncervical lower genital tract dysplasia, including vulvar, vaginal, or anal dysplasia, with 13 (3.3%) diagnosed with high-grade dysplasia or worse (five were lower genital tract carcinoma [three anal, one vulvar, and one vaginal]). Ten (2.5%) developed both cervical and noncervical lower genital tract dysplasia. Black race was significantly associated with developing dysplasia (odds ratio [OR] 2.86; 95% CI 1.33-6.13) as was hydroxychloroquine use (OR 5.95; 95% CI 1.96-18.09). High-grade cervical dysplasia was diagnosed at a median interval of 3.18 years after transplant; noncervical high-grade lower genital tract dysplasia was diagnosed at a median interval of 3.94 years. CONCLUSIONS One in eight transplant recipients developed lower genital tract dysplasia and approximately half were high-grade dysplasia or cancer. Black race and hydroxychloroquine use were associated with an increased risk of dysplasia. Yearly cervical screening and comprehensive lower genital examination beyond the cervix is indicated in this population.

Abstract
Numerous systemic diseases (vasculitis, connective tissue disease or sarcoidosis) can display an involvement of the perianal skin, the rectum and/or the anus. Such knowledge is important in order to treat these complications specifically when possible. Lesions of the anorectum arising from systemic diseases can sometimes cause perforations in the peritoneal cavity (if concerning the higher portion of the rectum) and/or fistulization to the anal margin. Differential diagnosis, mostly infectious or inflammatory (Crohn's disease) must be ruled out in every case. Other systemic diseases can display specific manifestations as this is the case in scleroderma which can lead to anal incontinence. Despite the relative rarity of these manifestations, their ignorance would forbid global management of these complex diseases. It should thus be detected in each consultation and a regular follow-up must be provided with a proctologist and/or a gastroenterologist when needed.

Abstract
These guidelines from the American Society of Transplantation Infectious Diseases Community of Practice update the epidemiology and management of human papillomavirus (HPV) infections in organ transplant recipients. HPV is one of the most common sexually transmitted infections and is associated with cancers of the anogenital region. Increasing evidence suggests an association with head and neck cancers as well. Solid organ transplant recipients have a higher risk of HPV infection than the general population. Infection manifests as premalignant lesions, warts, or cancer of the cervix, penis, vulva, scrotum, and anal canal. Most are asymptomatic initially, so diagnosis can be difficult without screening. A vaccine is available though not effective in preventing all cancer-causing strains. Organ transplant recipients should be screened for HPV-associated cancers and appropriate therapy initiated in a timely manner. Further studies are warranted to delineate the most effective screening methods and therapeutic modalities, including whether changes in immunosuppression are effective in attenuating disease.

Abstract
Human papillomavirus (HPV) is a common infection in kidney transplant recipients. HPV causes cervical, anal, vulvar, vaginal, penile and head and neck cancers. Kidney transplant recipients have a disproportionate burden of disease given prolonged immunosuppression. Given the long pre-invasive state of precancer lesions such as cervical intraepithelial neoplasia (CIN) and anal intraepithelial neoplasia (AIN) most HPV-cancers are preventable with screening and targeted treatment of disease. Pre-transplant vaccination of age-eligible kidney transplant recipients is otherwise ideal.

The 28-year incidence of de novo malignancies after liver transplantation: A single-center analysis of risk factors and mortality in 1616 patients. Liver Transpl 2017; 23:1404-1414. [PMID: 28590598 DOI: 10.1002/lt.24795] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 05/08/2017] [Accepted: 05/14/2017] [Indexed: 12/13/2022]
Abstract
De novo malignancies (DNMs) are one of the leading causes of late mortality after liver transplantation (LT). We analyzed 1616 consecutive patients who underwent LT between 1988 and 2006 at our institution. All patients were prospectively observed over a study period of 28 years by our own outpatient clinic. Complete follow-up data were available for 96% of patients, 3% were incomplete, and only 1% were lost to follow-up. The median follow-up of the patients was 14.1 years. Variables with possible prognostic impact on the development of DNMs were analyzed, as was the incidence of malignancies compared with the nontransplant population by using standardized incidence ratios. In total, 266 (16.5%) patients developed 322 DNMs of the following subgroups: hematological malignancies (n = 49), skin cancer (n = 83), and nonskin solid organ tumors (SOT; n = 190). The probability of developing any DNM within 10 and 25 years was 12.9% and 23.0%, respectively. The respective probability of developing SOT was 7.8% and 16.2%. Mean age at time of diagnosis of SOT was 57.4 years (range, 18.3-81.1 years). In the multivariate analysis, an increased recipient age (hazard ratio [HR], 1.03; P < 0.001) and a history of smoking (HR, 1.92; P < 0.001) were significantly associated with development of SOT. Moreover, the development of SOT was significantly increased in cyclosporine A-treated compared with tacrolimus-treated patients (HR, 1.53; P = 0.03). The present analysis shows a disproportionate increase of de novo SOT with an increasing follow-up period. Increased age and a history of smoking are confirmed as major risk factors. Moreover, the importance of immunosuppression is highlighted. Liver Transplantation 23 1404-1414 2017 AASLD.

Abstract
Solid organ transplant recipients are at increased risk of developing several human papillomavirus (HPV)-related malignancies, including cervical and anal cancers. The purpose of this prospective study was to assess the initial prevalence and risk factors for high-risk HPV (HR-HPV) cervical infections in liver transplant recipients, as well as their concordance with anal infections. A total of 50 female patients were enrolled in the Department of General, Transplant and Liver Surgery at the Medical University of Warsaw (center with >1600 liver transplantations). The initial prevalence of cervical HR-HPV infection was 10.0% (5/50). The only significant risk factor for cervical HR-HPV infection was ≥4 lifetime sexual partners (P=.037). Statistical tendencies toward higher prevalence of cervical HR-HPV infections were found for patients with hepatitis B virus (HBV, P=.082) and with model for end-stage liver disease (MELD) score ≤8 (P=.064). Cervical cytology was abnormal in 10 patients, including three with HR-HPV. Out of 12 patients with available data on anal HR-HPV, one had concordant HPV 16 infection. In conclusion, the initial prevalence of high-risk HPV infection is relatively low, except for patients with ≥4 previous sexual partners and potentially in those with HBV and/or low MELD score.

Abstract
Over 26 years, we found 46 infectious episodes in 350 kidney transplant recipients. Fifteen were urinary tract infections, recurrent in 4 patients. There were 8 cytomegalovirus infections, three of them fatal when intravenous (IV) ganciclovir was not available. Seven patients had a reactivation of tuberculosis (TB) in the pleura, cervical spine, lumbar spine, knee, ankle, skin and peritoneum, respectively, and were all resolved satisfactorily with conventional anti-TB therapy. Three patients transplanted before routine prophylaxis with the use of acyclovir developed an extensive herpes zoster infection in the 1st 6 months after transplantation, which was resolved with the use of oral acyclovir, and 1 had a disseminated herpes simplex infection resolved with the use of IV acyclovir. Three patients transplanted before routine prophylaxis with trimethoprim sulfa developed Pneumocystis carinii pneumonia in the 1st 6 months after transplantation, which was fatal in one of them. In 2 patients, we found a Nocardia infection, confined to the lung, which was cured in one of the cases and systemic and fatal in the other. Two patients transplanted before routine prophylaxis with the use of nystatin developed esophageal candidiasis in the 1st 6 months after transplantation. One patient developed infective endocarditis in a stenotic bicuspid aortic valve and died 10 years later after another incident of infective endocarditis at the prosthetic aortic valve. Two patients developed an extensive condyloma at the penis, perianal region, and perineum owing to human papillomavirus, requiring extensive surgical resection and podophyllin applications. Another patient developed fatal post-transplantation lymphoproliferative disease due to Epstein-Barr virus infection 15 years after transplantation. One patient developed a severe and fatal mucocutaneous leishmaniasis with no response to conventional antimonial therapy. It is interesting to note that despite Chagas disease being endemic in Bolivia, we had no patients with reactivation or transmission through the graft even though many of the patients and donors were serologically positive for Chagas disease.

Abstract
Adult-onset Still disease (AOSD) is a systemic autoimmune disease (AIID) that can develop after exposure to infectious agents. Genital human papillomavirus (HPV) infection has been reported to induce or exacerbate AIIDs, such as systemic lupus erythematosus (SLE). No guidelines are available for the management of genital warts in AOSD. Case report and literature review. We report a patient who was diagnosed AOSD in the setting of refractory and recurrent genital HPV infection, demonstrating a possible link between HPV infection and AOSD. In addition, we also discuss the management of genital warts in patients with AOSD. To the best of our knowledge, no previous cases of AOSD with genital HPV infection have been reported in literature. We then conclude that the patient AOSD may be triggered by primary HPV infection. Larger number of patient samples is needed to confirm whether HPV could trigger AOSD.

Abstract
BACKGROUND Treatment-related immunosuppression in organ transplant recipients has been linked to increased incidence and risk of progression for several malignancies. Using a population-based cancer cohort, we evaluated whether organ transplantation was associated with worse prognosis in elderly patients with non-small cell lung cancer (NSCLC). METHODS Using the Surveillance, Epidemiology, and End Results Registry linked to Medicare claims, we identified 597 patients aged 65 years or older with NSCLC who had received organ transplants (kidney, liver, heart, or lung) before cancer diagnosis. These cases were compared to 114,410 untransplanted NSCLC patients. We compared overall survival (OS) by transplant status using Kaplan-Meier methods and Cox regression. To account for an increased risk of non-lung cancer death (competing risks) in transplant recipients, we used conditional probability function (CPF) analyses. Multiple CPF regression was used to evaluate lung cancer prognosis in organ transplant recipients while adjusting for confounders. RESULTS Transplant recipients presented with earlier stage lung cancer (P = 0.002) and were more likely to have squamous cell carcinoma (P = 0.02). Cox regression analyses showed that having received a non-lung organ transplant was associated with poorer OS (P < 0.05), whereas lung transplantation was associated with no difference in prognosis. After accounting for competing risks of death using CPF regression, no differences in cancer-specific survival were noted between non-lung transplant recipients and nontransplant patients. CONCLUSIONS Non-lung solid organ transplant recipients who developed NSCLC had worse OS than nontransplant recipients due to competing risks of death. Lung cancer-specific survival analyses suggest that NSCLC tumor behavior may be similar in these 2 groups.

Abstract
OBJECTIVES The objective of this study is to analyze the clinical outcomes of abnormal cervical cytology and newly diagnosed human papillomavirus (HPV)-related disease after organ transplantation. MATERIALS AND METHODS Medical records from July 2004 to August 2015 were reviewed, and thirteen patients were identified who had been newly diagnosed with HPV-related disease (cervical intraepithelial neoplasia [CIN] and cervical cancer) after organ transplantation. The median transition time to the aggravation of cervical cytology and the spontaneous regression rate of CIN were evaluated. Clinical outcomes of CIN1 and CIN2 were compared between the general population and patients with organ transplantation. We also reviewed the current literature regarding the incidence of HPV infection, Pap smear abnormality and/or CIN after organ transplantation. RESULTS The cervical cytology aggravated in nine of the 13 patients (69 %). In seven of the 13 cases (54 %), treatments such as cervical conization, laser vaporization, or radiation therapy, were conducted. HPV-related disease disappeared after treatment in only three of the seven actively treated cases (43 %). In contrast, the lesions persisted in three (43 %) cases after treatment. One patient died from cervical cancer. The spontaneous regression rate of the HPV-related diseases, if left untreated, was 0 %. There was a statistically significant difference in the clinical outcomes of CIN1 and CIN2 between the general population and patients with organ transplantation (p = 0.0026 and 0.0315, respectively; chi-squared test). CONCLUSIONS HPV-related lesions that are newly diagnosed after organ transplantation do not seem to regress as spontaneously as in the general population. Physicians should recognize the importance of close monitoring and long-term follow-up.

Abstract
INTRODUCTION Development of cancer after transplantation has rapidly became one of the leading causes of death in kidney transplant recipients with functioning grafts. Anogenital malignant neoplasms may occur with a 14-fold increased incidence, and human papilloma virus (HPV) infection has been recently identified as the leading cause of cervical carcinoma. We report the preliminary findings of a prospective study that evaluated the incidence of HPV infection and cervical carcinoma in a population of kidney transplant recipients. PATIENTS AND METHODS The study included 35 female recipients of a deceased donor kidney with at least 6 months of follow-up. All patients underwent a cervicovaginal brushing, an HPV DNA test, and a Papanicolaou test. RESULTS Twenty-two patients (62.8%) were positive for HPV DNA. Thirteen of 22 HPV DNA-positive recipients (59%) demonstrated a high-risk HPV genotype. No cytologic anomalies were detected in Papanicolaou smears. CONCLUSIONS These preliminary data demonstrated a high incidence of HPV infection in renal transplant recipients. Most of our recipients exhibited a high-risk HPV genotype, which suggests higher aggressiveness of such infection in immunosuppressed patients. The HPV test is useful to monitor patients at higher risk of anogenital malignant neoplasms by identifying the cytologic anomalies at an earlier stage. This ongoing study will investigate the rate of progression of HPV infection and the clinical patterns of HPV-positive cytologic anomalies in renal transplant recipients.

Abstract
Immunosuppressive treatment of organ transplant recipients is associated with an increase in the occurrence of human papillomavirus (HPV) related anogenital (pre)malignancies. This cohort study investigated the genotype-specific prevalence of HPV infections in a large cohort of female renal transplant recipients (RTRs). Participants self-collected a cervicovaginal sample for detection and genotyping of HPV. Besides, they completed a questionnaire regarding sociodemographic variables, medical data and sexual behavior. Anogenital screening was offered to all HPV-positive participants. A total number of 218 female RTRs was included. The prevalence of mucosal HPV infections was 27.1% and 17.4% for high risk HPV in particular. The studied cohort showed a broad range of HPV genotypes and multiple HPV genotypes were found in 27.1% of HPV-positive patients. Seven participants were identified with occult premalignant anogenital lesions. In conclusion, this study shows a high point-prevalence of HPV in female RTRs (age-matched West-European general population: 9-10%) with a shift in the distribution of genotypes as compared with the general population. Moreover, a substantial number of patients with occult premalignancies was identified. The introduction of self-sampling for HPV positivity can help in early detection of (pre)malignant anogenital lesions in this vulnerable population.

Abstract
Human papillomaviruses (HPVs) are a large family of double strand DNA viruses comprising more than 180 types. Infection with HPV is very common and it is associated with benign and malignant proliferation of skin and squamous mucosae. Many HPVs, considered low-risk such as HPV 6 and 11, produce warts; while high-risk viruses, such as HPVs 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, and 58, induce tumors. About 5% of all cancers in men and women are associated with HPV infection. Because there are not antiviral drugs for HPV infection, current therapies for low-risk HPV infections involve physical removal of the lesion by cryotherapy, trichloracetic acid, laser, or surgical removal. Surgical procedures are effective in the treatment of pre-cancerous lesions, however after these procedures, many recurrences appear due to new re-infections, or to failure of the procedure to eliminate the HPV. In addition, HPV can inhibit recognition of malignant cells by the immune system, leading to the development of cancer lesions. When this occurs, radiotherapy and chemotherapy are then used. Unfortunately, about 50% of the HPV-cancer patients still die. In the past decade, a better knowledge of the natural history of the virus-host interaction and of the immune response against this viral infection has brought new therapeutic strategies geared to modulate the immune system to generate an efficient virus-specific cytotoxic response. Novel HPV protein-expressing vaccines have shown some significant clinical efficacy and systemic HPV-specific cytotoxic T cell responses. This review will describe the current status of the several therapeutic strategies used to treat HPV-induced lesions, and discuss the various new therapies now being tested.

Abstract
At mucosal sites, papillomavirus genomes can persist in the epithelial basal layer following immune-mediated regression. Subsequent T-cell depletion stimulates a 3- to 5-log increase in the viral copy number, to levels associated with productive infection. Reappearance of microlesions was rare within the short time frame of our experiments but was observed in one instance. Our studies provide direct evidence that immunosuppression can trigger the reactivation of latent papillomavirus genomes, as previously proposed in humans.

Abstract
Solid organ transplant recipients are at risk of morbidity from human papillomavirus (HPV)-related diseases. Quadrivalent HPV vaccine is recommended for posttransplant patients but there are no data on vaccine immunogenicity. We determined the immunogenicity of HPV vaccine in a cohort of young adult transplant patients. Patients were immunized with three doses of quadrivalent HPV vaccine containing viral types 6, 11, 16 and 18. Immunogenicity was determined by type-specific viral-like protein ELISA. Four weeks after the last dose of vaccine, a vaccine response was seen in 63.2%, 68.4%, 63.2% and 52.6% for HPV 6, 11, 16 and 18, respectively. Factors that led to reduced immunogenicity were vaccination early after transplant (p = 0.019), having a lung transplant (p = 0.007) and having higher tacrolimus levels (p = 0.048). At 12 months, there were significant declines in antibody titer for all HPV types although the number of patients who remained seropositive did not significantly differ. The vaccine was safe and well tolerated. We show suboptimal immunogenicity of HPV vaccine in transplant patients. This is important for counseling patients who choose to receive this vaccine. Further studies are needed to determine an optimal HPV vaccine type and schedule for this population.

Abstract
Model systems show that papillomavirus DNA can persist after lesion-regression, and be maintained in a subset of epithelial basal cells. These are very likely long-lived 'stem-cells' or 'stem-like cells', with latency arising via at least two distinct mechanisms. The first involves low-titre virus infection and the retention of viral DNA at levels that are too low to allow life-cycle completion. The second involves lesion-formation, and clearance by the adaptive immune system, followed by persistence with low-level viral gene expression, and possible reactivation upon immune depletion. Mechanical irritation, inflammation and other extracellular influences affect viral copy number in the latently infected cell, and may predispose to lesion-reappearance. Reactivation may account for the recurrence of 'apparently cleared' cervical lesions caused by high-risk types, the appearance of Beta HPV-lesions following immunosuppression, and the development of recurrent respiratory papillomatosis in afflicted children.

BACKGROUND Atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intra-epithelial lesions (LSIL) are minor lesions of the cervical epithelium, detectable by cytological examination of cells collected from the surface of the cervix of a woman.Usually, women with ASCUS and LSIL do not have cervical (pre-) cancer, however a substantial proportion of them do have underlying high-grade cervical intra-epithelial neoplasia (CIN, grade 2 or 3) and so are at increased risk for developing cervical cancer. Therefore, accurate triage of women with ASCUS or LSIL is required to identify those who need further management.This review evaluates two ways to triage women with ASCUS or LSIL: repeating the cytological test, and DNA testing for high-risk types of the human papillomavirus (hrHPV) - the main causal factor of cervical cancer. OBJECTIVES Main objective To compare the accuracy of hrHPV testing with the Hybrid Capture 2 (HC2) assay against that of repeat cytology for detection of underlying cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) or grade 3 or worse (CIN3+) in women with ASCUS or LSIL. For the HC2 assay, a positive result was defined as proposed by the manufacturer. For repeat cytology, different cut-offs were used to define positivity: Atypical squamous cells of undetermined significance or worse (ASCUS+), low-grade squamous intra-epithelial lesions or worse (LSIL+) or high-grade squamous intra-epithelial lesions or worse (HSIL+).Secondary objective To assess the accuracy of the HC2 assay to detect CIN2+ or CIN3+ in women with ASCUS or LSIL in a larger group of reports of studies that applied hrHPV testing and the reference standard (coloscopy and biopsy), irrespective whether or not repeat cytology was done. SEARCH METHODS We made a comprehensive literature search that included the Cochrane Register of Diagnostic Test Accuracy Studies; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (through PubMed), and EMBASE (last search 6 January 2011). Selected journals likely to contain relevant papers were handsearched from 1992 to 2010 (December). We also searched CERVIX, the bibliographic database of the Unit of Cancer Epidemiology at the Scientific Institute of Public Health (Brussels, Belgium) which contains more than 20,000 references on cervical cancer.More recent searches, up to December 2012, targeted reports on the accuracy of triage of ASCUS or LSIL with other HPV DNA assays, or HPV RNA assays and other molecular markers. These searches will be used for new Cochrane reviews as well as for updates of the current review. SELECTION CRITERIA Studies eligible for inclusion in the review had to include: women presenting with a cervical cytology result of ASCUS or LSIL, who had undergone both HC2 testing and repeat cytology, or HC2 testing alone, and were subsequently subjected to reference standard verification with colposcopy and colposcopy-directed biopsies for histologic verification. DATA COLLECTION AND ANALYSIS The review authors independently extracted data from the selected studies, and obtained additional data from report authors.Two groups of meta-analyses were performed: group I concerned triage of women with ASCUS, group II concerned women with LSIL. The bivariate model (METADAS-macro in SAS) was used to assess the absolute accuracy of the triage tests in both groups as well as the differences in accuracy between the triage tests. MAIN RESULTS The pooled sensitivity of HC2 was significantly higher than that of repeat cytology at cut-off ASCUS+ to detect CIN2+ in both triage of ASCUS and LSIL (relative sensitivity of 1.27 (95% CI 1.16 to 1.39; P value < 0.0001) and 1.23 (95% CI 1.06 to 1.4; P value 0.007), respectively. In ASCUS triage, the pooled specificity of the triage methods did not differ significantly from each other (relative specificity: 0.99 (95% CI 0.97 to 1.03; P value 0.98)). However, the specificity of HC2 was substantially, and significantly, lower than that of repeat cytology in the triage of LSIL (relative specificity: 0.66 (95% CI 0.58 to 0.75) P value < 0.0001). AUTHORS' CONCLUSIONS HPV-triage with HC2 can be recommended to triage women with ASCUS because it has higher accuracy (significantly higher sensitivity, and similar specificity) than repeat cytology. When triaging women with LSIL, an HC2 test yields a significantly higher sensitivity, but a significantly lower specificity, compared to a repeat cytology. Therefore, practice recommendations for management of women with LSIL should be balanced, taking local circumstances into account.

Abstract
The presence of viral DNA in the absence of disease has suggested that papillomaviruses, like many other viruses, can exist as latent infections in the skin or other epithelial sites. In animal models, where detailed investigation has been carried out, papillomavirus DNA can be found at sites of previous infection following immune regression, with the site of latent infection being the epithelial basal layer. Such studies suggest that immune surveillance can restrict viral gene expression in the basal and parabasal layers without efficiently suppressing viral genome replication, most probably through the action of memory T-cells in the skin or dermis. Although gradual papillomavirus genome loss appears to occur over time at latent sites, immunosuppression can arrest this, and can lead to an elevation in viral genome copy number in experimental systems. In addition to immune-mediated latency, it appears that a similar situation can be achieved following infection at low virus titres and/or infection at epithelial sites where the virus life cycle is not properly supported. Such silent of asymptomatic infections do not necessarily involve the host immune system and may be controlled by different mechanisms. It appears that virus reactivation can be triggered by mechanical irritation, wounding or by UV irradiation which changes the local environment. Although the duration of papillomavirus latency in humans is not yet known, it is likely that some of the basic principles will resemble those elucidated in these model systems, and that persistence in the absence of disease may be the default outcome for at least some period of time following regression.

Abstract
Recipients of liver transplantation (LT) have a higher overall risk (2-3 times on average) of developing de novo malignancies than the general population, with standardized incidence ratios ranging from 1.0 for breast and prostate cancers to 3-4 for colon cancer and up to 12 for esophageal and oropharyngeal cancers. Aside from immunosuppression, other identified risk factors for de novo malignancies include the patient's age, a history of alcoholic liver disease or primary sclerosing cholangitis, smoking, and viral infections with oncogenic potential. Despite outcome studies showing that de novo malignancies are major causes of mortality and morbidity after LT, there are no guidelines for cancer surveillance protocols or immunosuppression protocols to lower the incidence of de novo cancers. Patient education, particularly for smoking cessation and excess sun avoidance, and regular clinical follow-up remain the standard of care. Further research in epidemiology, risk factors, and the effectiveness of screening and management protocols is needed to develop evidence-based guidelines for the prevention and treatment of de novo malignancies.

Abstract
This article outlines the biology of human papillomavirus (HPV) infection of human mucosa and the cellular pathways that are altered through viral infection. The article provides a conceptual framework with which to understand the 2 major immunologic strategies to address HPV-related diseases: (1) prevention of primary HPV infection through the use of prophylactic vaccines and (2) treatment of established infection and diseases through therapeutic vaccines. Nonimmunologic therapy that targets cellular dysregulation induced by HPV infection is also discussed. The challenges in actualizing these conceptually attractive therapies on both a societal and biological level are examined.

Abstract
BACKGROUND Renal allograft recipients are reported to have a higher incidence of malignancy than the general population. This single hospital-based study examined the incidence and clinicopathologic behavior of uterine cervical carcinoma in renal transplant recipients. METHODS Among 453 women receiving renal transplantation from January 1990 to December 2008, 5 patients were diagnosed with cervical carcinoma. Medical records of these 5 patients were retrospectively reviewed, and clinicopathologic data were collected and analyzed. RESULTS The incidence of cervical carcinoma in renal transplant recipients was 58.1 out of 100,000 per year, which is 3.5 times higher than in the general Korean population. The mean interval between the time of renal transplantation and the time of cervical carcinoma diagnosis was 80.7 months. After a median follow-up of 96.2 months, there was no recurrence of the disease or death. In 4 patients who were positive from human papillomavirus in situ hybridization (HPV ISH), high or probably high risk HPV DNA was detected in all. Punctate staining of HPV ISH was detected in 3 out of 4 patients. CONCLUSIONS Higher incidence of cervical carcinoma is expected in renal transplant recipients, so appropriate surveillance is needed to ensure early detection and treatment of cervical carcinoma.

Abstract
Treatment advances achieved over the last few years have radically changed the management of patients with autoimmune inflammatory diseases requiring conventional or biological immunosuppressive therapy. These diseases and the drugs used to treat them increase the rate of infections, including genital infections due to the human Papillomavirus (HPV). Genital HPV infections have been extensively studied in organ transplant recipients, HIV-infected patients, and patients with congenital immune deficiencies. Although genital HPV infections usually manifest as benign lesions of the external genital organs (condylomata), they are associated with an increased risk of cancer. Very few data are available on genital HPV infections associated with autoimmune inflammatory diseases or their treatments. Here, we review the published information on this topic.

Abstract
Human papillomavirus (HPV) is the etiological agent of cervical cancer, the second most prevalent neoplasia among women. Although it has been proven that systemic lupus erythematosus (SLE) patients have higher frequency of cervical dysplasia, few studies have focused on HPV prevalence among them. This study aimed to investigate HPV prevalence among SLE patients and to evaluate associated risk factors, including the use of immunosuppressors (IM). Total DNA extracted from cervical samples of 173 SLE patients and 217 women (control group) submitted to routine cervical cytopathology was used as template in polymerase chain reaction (PCR)-based assays for detection of HPV DNA. HPV genotyping was performed by type-specific PCR, PCR-RFLP and/or DNA sequencing. Statistical methods included univariate analysis and logistic regression. Despite presenting significantly fewer HPV risk factors, SLE patients were found to have a threefold increase in HPV infection, mostly genotypes 53, 58, 45, 66, 6, 84, 83, 61, as compared with controls, who presented types 6, 18 and 61 more frequently. The higher rate of HPV infection was associated with immunosuppressive therapy. This study provides evidence that SLE patients have a high prevalence of HPV infection, which is even higher with the use of IM, a condition that might necessitate a more frequent cervical cancer screening program for these women.

Abstract
BACKGROUND We conducted a case-control study to examine the relationship between human leukocyte antigen-A (HLA-A) allele polymorphism and the pathogenesis of cervical neoplasia among Japanese women. METHODS A total of 119 patients with invasive cervical squamous cell carcinoma were compared to 119 age- and menopausal status-matched non-cancer controls. Blood samples were taken from all cases and controls and lifestyle information was collected by means of a self-administered questionnaire. The estimated impact of HLA-A alleles on cervical cancer risk was evaluated by unconditional logistic regression models. RESULTS The frequency of HLA-A(*)0206 among cases was significantly lower than among controls (P = 0.006). There was an inverse association between A(*)0206 and cervical cancer risk (odds ratio [OR] = 0.31, 95% confidence interval [95% CI] = 0.15 to 0.65, P = 0.002), and a positive association for HLA-A(*)2402 (OR = 1.76, 95% CI = 1.00 to 3.09, P = 0.048). After correction for multiple comparisons, A(*)0206 was significantly associated with reduced cervical cancer risk (corrected P = 0.036). Furthermore, the inverse association between A(*)0206 and cervical cancer risk was independent of smoking status (never smoker: OR = 0.37, 95% CI = 0.15 to 0.90; ever smoker: OR = 0.23, 95% CI = 0.06 to 0.89). CONCLUSIONS There was an inverse association between HLA-A(*)0206 and cervical cancer risk among Japanese women, which suggests that HLA-A polymorphism influences cervical cancer risk. Further investigation in other populations is thus warranted.

Abstract
Human papillomavirus (HPV) infections are generally long lasting, and a host immune response to infection is hard to detect. Nevertheless immunocompromised subjects control HPV infection less well than those with intact immunity. Immune responses are best documented for the papillomavirus groups that cause evident human disease, particularly those responsible for anogenital cancers and genital warts. Humoral immunity to the viral capsid has been shown sufficient for protection against infection, while innate and adaptive cell mediated immunity appears important for eventual elimination of HPV infection. However, molecular and cellular mechanisms responsible for protection from and clearance of HPV infection are not completely established.
