Anogenital giant condyloma in an infant with liver transplantation.

Human papillomavirus (HPV) types 6 and 11 were detected in a 3-year-old girl with extensive anogenital condylomata. Although sexual abuse must be considered, non-sexual transmission is evident in at least 57% of children with anogenital warts. Perinatal transmission may occur in approximately 24.5% of infants born to HPV-positive mothers. We present an immunosuppressed child with giant condylomata and discuss transmission, work up, and treatment.

Prevalence and sociodemographic correlates of anogenital Human Papillomavirus (HPV) carriage in a cross-sectional, multi-ethnic, community-based Asian male population.

BACKGROUND: Addressing the burden of HPV-associated diseases among men is increasingly becoming a public health issue. The main objective of this study was to determine HPV prevalence among a healthy community-based Malaysian men. METHOD: This was a cross-sectional study that recruited 503 healthy males from 3 community-based clinics in Selangor, Malaysia. Genital and anal samples were collected from each participant for 14 high risk and 2 low risk HPV DNA detection and genotyping. All participants responded to a set of detailed sociodemographic and sexual behaviour questionnaire. RESULTS: The median age at enrolment was 40 years old (IQR: 31-50). The anogenital HPV6/11 prevalence was 3.2% whereas high risk HPV prevalence was 27.1%. The genital HPV prevalence for HPV6/11 was 2.9% while high risk HPV was 18.8%. HPV6/11 prevalence in the anal canal was 1.6% and high risk HPV was 12.7%. HPV 18 was the most prevalent genotype detected in the anogenital area. There was a significant independent association between genital and anal HPV infections. CONCLUSION: Anogenital HPV infection is common among Malaysian men. These findings emphasize the ubiquity of HPV infection and thus the value of population-wide access to HPV prevention.

Factors Related to Extralaryngeal Spread in Juvenile Recurrent Respiratory Papillomatosis.

OBJECTIVES/HYPOTHESIS: To identify factors associated to increased risk of extra-laryngeal spread in pediatric patients with recurrent respiratory papillomatosis (RRP). STUDY DESIGN: Retrospective chart review. METHODS: A retrospective study was conducted evaluating the clinical charts of patients younger than 16 years with histopathologically confirmed RRP treated between January 2014 and December 2018. Characteristics of patients with and without extra-laryngeal disease dissemination were compared. Odds ratios were calculated and multivariate logistic regression analysis was performed. RESULTS: Data from 82 patients were analyzed. Mean age at symptom onset was 42 months. Fifteen (18.29%) patients had extra-laryngeal spread (ELS) at time of diagnosis and in four, the disease continued to spread to other sites. Of 67 patients with disease restricted to the larynx, 17 (25.37%) developed ELS during the disease course. Human papilloma virus (HPV) typing was performed in 49 (59.8%) patients; in 28 (57.1%) HPV subtype 6 was identified and in 21 (42.9%) HPV subtype 11. ELS was found in 11 patients with serotype 11 (52.38%) and in seven patients with serotype 6 (25%) (P = .048). Statistically significant differences for ELS were also found for age at diagnosis younger than 5 years (P = .045), presence of tracheostomy (P = .031), and need for adjuvant therapy (P = .010). CONCLUSIONS: Age at diagnosis of RRP younger than 5 years and presence of tracheostomy were factors related to ELS. A statistically significant association between infection with HPV subtype 11 and ELS were also observed. Adjuvant medication might be considered a protective factor against ELS.

Contemporary human papillomavirus genotyping and correlations to peniscopy, cytology, and histopatology on over 1000 males.

OBJECTIVES: To explore male human papillomavirus (HPV) contemporary genotyping epidemiology and correlations to peniscopy, cytology, and histopatology. METHODS: Medical records of patients who had been submitted to HPV infection screening with genotyping, peniscopy, cytology, and histopathology in a period of 2 years were reviewed. Frequency analysis and correlations between the diagnostic tools were established. RESULTS: Genotype of 1132 men resulted in 69.2% (784) positivity for HPV DNA, 78% classified as high risk of oncogenesis. Co-infections occurred in 429 (54.7%) and the most frequently identified types were HPV-6, HPV-42, and HPV-16, in 133 (17%), 94 (12%), and 86 (11%) patients, respectively. Positive/negative predictive values of peniscopy, cytology, and histopathology were 83/31%, 92/32%, and 87/33%, respectively. As a result, though significant, the correlations between genotype and non-molecular tests were poor. CONCLUSIONS: In the current contemporary representative male cohort, over two thirds are positive for human HPV DNA, 78% of high risk and with over half co-infections. Though significant, its correlation with non-molecular tests is poor and while the positive predictive values of peniscopy, cytology, and histopatology are between 83% and 92%, their negative predictive values are as low as 31% to 33%.

Safety and clinical activity of PD-L1 blockade in patients with aggressive recurrent respiratory papillomatosis.

BACKGROUND: Recurrent respiratory papillomatosis (RRP) is a human papillomavirus (HPV)-driven disorder that causes substantial morbidity and can lead to fatal distal airway obstruction and post-obstructive pneumonias. Patients require frequent surgical debridement of disease, and no approved systemic adjuvant therapies exist. METHODS: A phase II study was conducted to investigate the clinical activity and safety of programmed death-ligand 1 (PD-L1) blockade with avelumab in patients with RRP. RESULTS: Twelve patients were treated. All patients with laryngeal RRP displayed improvement in disease burden, and 5 of 9 (56%) displayed partial responses. None of 4 patients with pulmonary RRP displayed a response. Using each patient's surgical history as their own control, patients required fewer surgical interventions after avelumab treatment (p = 0.008). A subset of partial responders developed HPV-specific reactivity in papilloma-infiltrating T-cells that correlated with reduced HPV viral load and an increased Tissue Inflammation Signature. CONCLUSIONS: Avelumab demonstrated safety and clinical activity in patients with laryngeal RRP. Further study of immune checkpoint blockade for RRP, possibly with longer treatment duration or in combination with other immunotherapies aimed at activating antiviral immunity, is warranted. TRIAL REGISTRATION: NCT, number NCT02859454 , registered August 9, 2016.

Condyloma acuminata on the nipple and coronary sulcus of the penis: A case report.

RATIONALE: Condyloma acuminatum (CA) is a benign tumor primarily caused by infection with human papillomavirus (HPV) type-6 or type-11, lesions of which are most frequently found on the genital and perianal squamous mucosa and skin. CA outside the genitals is not common. PATIENT CONCERNS: A 29-year-old male presented with lesions on the left nipple and coronary sulcus after heterosexual contact. DIAGNOSES: Histopathological examination and HPV detection made a definite diagnosis of CA. INTERVENTION: The patient was treated with microwave and topical imiquimod cream. OUTCOMES: After 6 months follow-up, there was no sign of recurrence. LESSONS: This case shows that we should pay more attention to CA outside the genitals in the process of diagnosis and treatment.

Implication of low risk human papillomaviruses, HPV6 and HPV11 in laryngeal papillomatosis in Burkina Faso.

PURPOSE: Laryngeal papillomatosis is the most common benign tumor of the larynx of children. It is characterized by the development of exophytic proliferative lesions in the mucosa of the airways. Human papillomavirus (HPV) has been recognized as a causal agent among which HPV types 6 and 11 are the most frequently implicated. This disease affects the vocal cords and other important functions of the child. The difficulty of treatment is related to the high recurrence of papilloma growth after surgical removal. The objective of this study was to describe the implication of HPV6 and HPV11 in cases of laryngeal papillomatosis histologically confirmed in Ouagadougou. MATERIALS AND METHODS: This was a descriptive cross-sectional study based on histologically diagnosed archival tissue; obtained in the last ten years (2007 to 2017) in the anatomy and cyto-pathology laboratories in Burkina Faso. These fixed and paraffin-embedded tissues were deparaffinized with xylene before HPV DNA extraction; then HPV6 and HPV 11 were identified by real-time multiplex PCR. RESULTS: The prevalence of low-risk HPV infection (HPV-LR) was 54.84% in histologically confirmed laryngeal papillomatosis in Ouagadougou. Among the HPV-LR positive samples, HPV6 and HPV11 genotype prevalence's were respectively 41.17% and 35.3% while the HPV6 / HPV11 co-infection was 23.53%. CONCLUSIONS: The results show the implication of HPV6 and HPV11 in laryngeal papillomatosis in Burkina Faso with a high prevalence.

HPV 6-associated HSIL/Squamous Carcinoma in the Anogenital Tract.

Human papillomavirus (HPV) type 6 is historically classified as low-risk HPV type and associates with low-grade squamous intraepithelial lesions of the anogenital tract. Rare squamous carcinomas have been reported in association with these HPV types but the mechanism(s) behind this carcinogenic sequence have been unclear. We report 4 cases of low risk anogenital HPV infections-3 cervical (immature low-grade squamous intraepithelial lesion with metaplastic phenotype) and one anal (exophytic condyloma) lesion-that manifested with high-grade squamous intraepithelial lesion/squamous cell carcinoma. Two were associated with invasion one of which metastasized to a regional node. Two cases exhibited strong p53 positivity in the high-grade squamous intraepithelial lesion/squamous cell carcinoma component analogous to that seen in HPV-negative differentiated intraepithelial lesions of the external genitalia. This series of cases adds to the literature on low risk HPV-associated cervical squamous carcinomas. It underscores the similarities between the baseline cyto-morphology and benign mimics (low-grade squamous intraepithelial lesions), the subtle cytologic and immunohistochemical (MIB1) features heralding biologic aggressiveness, and in some potential pathways (p53) not usually involved in HPV-related anogenital neoplasia.

Prevalence and determinants of anal human papillomavirus infection in men who have sex with men and transgender women.

Human papillomavirus (HPV) prevalence varies by population. This study investigated anal HPV type detection risk by country in a population of men who have sex with men (MSM) and transgender women (TW) at risk of HIV. Sexually active HIV-1-uninfected MSM and TW were enrolled at eight sites: four in the United States (US), two in Thailand, one in Peru, and one in South Africa. Baseline anal HPV swabs were collected, and DNA typing was performed. One hundred and ninety-five participants, 76 (42%) from the US, had a mean age of 30.9 years (range 18-64). In 182 participants with results available, anal HPV infection was common with 169 (93%) with ≥1 type, 132 (73%) with ≥1 nine-valent vaccine types, and 66 (36%) with HPV 16. Participants in the US had a higher prevalence of HPV 16 (56%, p = 0.004) and HPV 6 (69%, p < 0.001) compared to the other regions. Stimulant drug use was significantly associated with HPV 6 detection. Anal HPV is highly prevalent in this population of MSM and TW sampled from four countries, with HPV 16 the most commonly detected type. The nine-valent HPV vaccine has the potential to provide significant protection if given prior to exposure.

Successful treatment of giant condyloma in a pediatric heart transplant recipient with topical cidofovir.

We report a case of giant condyloma that developed in a pediatric heart transplant recipient. This infection progressed for several months despite reduction in immunosuppression, topical treatment, and oral cimetidine therapy. Complete resolution was observed following 7 months of topical cidofovir, without evidence of systemic toxicity or rejection.

Effectiveness of physically ablative and pharmacological treatments for anal condyloma in HIV-infected men.

BACKGROUND: There is limited information on the effectiveness of available treatments for anal condyloma acuminata in HIV-1-infected men. AIM: To provide data on the effectiveness of electrosurgical excision, infrared coagulation and pharmacological (imiquimod) treatments for anal condyloma acuminata (peri-anal and/or intra-anal) in HIV-1-infected men based on authors' practice. METHODS: Single-center, retrospective descriptive analysis of HIV-1-infected men, 18 years or older treated for anal condyloma acuminata. Standard treatments were offered: electrosurgery excision, infrared coagulation and topical imiquimod. Effectiveness was evaluated by the recurrence rate at 1 year after treatment. Recurrence was defined as any anal condyloma acuminata diagnosed after 3 months of condyloma-free survival post-treatment. Anal cytology and human-papillomavirus-infection (HPV) was assessed. RESULTS: Between January 2005 and May 2009, 101 men were treated for anal condyloma acuminata: 65 (64%) with electrosurgery, 27 (27%) with infrared coagulation and 9 (9%) with imiquimod. At 1 year after treatment, the cumulative recurrence rate was 8% (4/65, 95%CI: 2-15%) with electrosurgery excision, 11% (3/27, 95%CI: 4-28%) with infrared coagulation and 11% (1/9, 95%CI: 2-44%) with imiquimod treatment. No predictive factors were associated with recurrence. Anal HPV-6 or HPV-11 was detectable in 98 (97%) patients and all had high-risk HPV genotypes, and 89 (88%) patients had abnormal anal canal cytology. Limitations: this was a retrospective descriptive analysis; limited to a single center; it cannot know if the recurrence is related to new infection. CONCLUSION: Recurrence of anal condyloma after any treatment was common. Abnormal anal cytology and high-risk HPV-infection were highly prevalent in this population, therefore at high-risk of anal cancer, and warrants careful follow-up.

Genital Wart and Human Papillomavirus Prevalence in Men in the United States From Penile Swabs: Results From National Health and Nutrition Examination Surveys.

INTRODUCTION: Human papillomavirus (HPV) is a common sexually transmitted infection in the United States that can lead to both malignant (high-risk) and benign (low-risk) findings. These low-risk findings include both genital condyloma, anal warts, and adult or juvenile papillomatosis, which are directly attributable to subtypes HPV 6 and HPV 11. We aim to estimate the prevalence of genital wart infections in men in the US population using a nationwide sample. METHODS: The NHANES database was queried for all men aged 18 to 59 years during the years 2013 to 2014. During these years, the survey included penile swabs that were tested for HPV infection from 37 subtypes using PCR. Information was also obtained regarding patient reported history of having a genital wart infection previously. RESULTS: A total of 1757 men had information regarding HPV DNA. Fifty-three men tested positive for HPV 6 or HPV 11 DNA. This corresponds to an estimated prevalence of 2.9% (95% confidence interval, 2.2-3.8) of men aged 18-59 years. In addition, 2.2% (95% confidence interval, 1.5-3.3) of men reported a history of genital wart infection. There was no significant association with genital HPV DNA detection with age. Increasing number of sexual partners was associated with higher rates of both genital warts and HPV 6 and HPV 11 DNA. CONCLUSIONS: The estimated prevalence of genital HPV DNA in the US male population is 2.9%. This burden of disease could potentially be lowered with increased usage of quadrivalent and nonavalent vaccinations.

Fast Ablation of Anogenital Warts of the Urinary Meatus by Low-dose Ingenol Mebutate Gel.

Therapeutic options of anogenital warts (AGW) at the urethral meatus are limited and often require effortful and time-consuming procedures under general anesthesia. Here, we present two cases of AGW at the urethral meatus, which we have successfully treated with low-dose topical ingenol mebutate gel.

Sinecatechins 10% ointment for genital warts: Case report of a beneficial reaction in an HIV-positive woman.

Patients with HIV infection are more likely to develop anogenital warts compared to HIV-negative people and are susceptible to treatment failures and recurrences. We report a case of extensive vulvar warts in an HIV-positive woman successfully treated with sinecatechins ointment. After the failure of a combination of cryotherapy and imiquimod 5% cream, we started therapy with sinecatechins 10% ointment. The patient developed an intense local inflammatory reaction after three weeks that induced the discontinuation of the therapy. After two weeks, we observed a complete regression of inflammation and a reduction of genital warts. The lesions completely regressed within a few weeks, with no relapse after eight months. Sinecatechins is a standardized extract of green tea leaves, effective in the treatment of external genital and perianal warts in immunocompetent patients, but their role has not been yet studied for immunocompromised people. Our case may represent a starting point for further studies, in order to evaluate the relation between treatment dosage, side effects, and drug response in immunocompromised patients.

Detection of human papillomavirus in urine among heterosexual men in relation to location of genital warts and circumcision status.

OBJECTIVE: Human papillomavirus (HPV) surveillance is important to monitor the effectiveness of national HPV vaccination programmes. Positivity of HPV in urine in men varies with different sampling methods. We aimed to determine the positivity for detection of HPV-6/11 in urine samples among men in relation to the position of genital warts and circumcision status. METHOD: We analysed stored chlamydia-positive urine specimens in young heterosexual men aged less than 25 years attending Melbourne Sexual Health Centre, Australia, between 2004 and 2015, for HPV genotypes. Positivity of HPV-6/11 and high-risk genotypes were stratified according to the position of genital warts and circumcision status. Positivity of HPV-6/11 was calculated using diagnosis of warts as the gold standard. Warts were classified as proximal penile warts from suprapubic area to midshaft of penis, and distal penile warts from distal shaft of penis to meatus. RESULTS: Of the 934 specimens, 253 (27.1%) men were positive for any HPV and 82 men (8.8%) had genital warts. The ORs of HPV-6/11 detection in urine were 4.63 (95% CI: 1.68 to 12.78) and 40.20 (95% CI: 19.78 to 81.70) times higher among men who had proximal penile warts and distal penile warts, respectively, compared with men who did not have genital warts. Circumcised men were less likely to have high-risk HPV (OR 0.31; 95% CI: 0.14 to 0.65) than uncircumcised men. Uncircumcised men were more likely to have distal penile warts than circumcised men (OR 8.22; 95% CI: 1.34 to 337.46). CONCLUSION: Positivity of HPV-6/11 in urine increases greatly in men with distal penile warts. Circumcised men are less likely to have distal penile warts, any HPV or high-risk HPV detected. Urine is likely to be an alternative sampling method for HPV-6/11 surveillance programme in men in countries with low circumcision rates.
