Although several studies have reported that oropharyngeal infection with HPV may predispose to tumorigenesis, little is known about the etiological factors of salivary gland tumors and the presence of HPV We studied 9 parotid lesions for HPV infection including an oncocytoma, an acinic cell carcinoma, a high-grade adenocarcinoma, a low-grade polymorphous adenocarcinoma, a Warthin's tumor and 2 pleomorphic adenomas, a lymphoepithelial cyst and a lipoma of the parotid gland. DNA was extracted from formalin-fixed and paraffin-embedded tissue sections. Solution PCR for HPV detection was performed using the GP5+/GP6+ primers, while HPV typing was carried out by multiplex PCR for HPV6, 11, 16, 18, and 33; positive samples were recorfirmed by PCR with specific primers for each type. Quantitative real-time PCR for the high-risk HPV genotypes 16, 18, 31, 33, 35, 52, 58 and 67 was also performed to quantitate the viral load. Finally, in situ PCR was employed with HPV16-specific primers by direct-detection method. Seven of the 9 parotid lesions were HPV positive while 6 of these 7 had been infected by HPV16 and/or HPV18 oncogenic types. High viral load of high-risk genotypes of HPV was found in the oncocytoma, in one of the pleomorphic adenomas, and in the Warthin's tumor. Finally, in situ PCR indicated that HPV16 amplification occurred in the salivary gland tumors. This is the first time that high-risk HPV genotypes are detected in these histological types of parotid lesions, suggesting the possible involvement of the virus in the disease.

SUMMARYInvestigating whether high-risk human papillomavirus (HR-HPV) types tend to become grouped in a particular way and whether factors are associated with such grouping is important for measuring the real impact of vaccination. In total, 219 women proving positive for HPV as detected by real-time PCR were included in the study. Each sample was analysed for detecting and quantifying six viral types and the hydroxymethylbilane synthase gene. Multiple correspondence analysis led to determining grouping patterns for six HR-HPV types and simultaneous association with multiple variables and whether viral load was related to the coexistence of other viral types. Two grouping profiles were identified: the first included HPV-16 and HPV-45 and the second profile was represented by HPV-31, HPV-33 and HPV-58. Variables such as origin, contraceptive method, births and pregnancies, educational level, healthcare affiliation regime, atypical squamous cells of undetermined significance and viral load were associated with these grouping profiles. Different socio-demographic characteristics were found when coinfection occurred by phylogenetically related HPV types and when coinfection was due to non-related types. Biological characteristics, the number of viral copies, temporality regarding acquiring infection and competition between viral types could influence the configuration of grouping patterns. Characteristics related to women and HPV, influence such interactions between coexisting HPV types reflecting the importance of their evaluation.

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

Minor salivary gland tumours are enigmatic in their behaviour and presentations. Histopathological diagnosis of these tumours encompasses a large spectrum. Conventionally, small nodular tumours of the upper lip or the labial mucosa are generally adenomas, frequently pleomorphic adenomas. Here, we describe a case of a solitary nodular tumour, occurring in the upper labial mucosa, diagnosed as sclerosing polycystic adenoma (SPA) with intraductal epithelial proliferation of high grade. This is a rare lesion, which has entered into the category of salivary gland tumours recently in the 2017 WHO categorisation. We report a case of paucicystic SPA with intraductal epithelial proliferations in the labial minor salivary gland of a 56-year-old woman, which might be the first report of a case occurring in the upper labial mucosa.

Penile intraepithelial neoplasia (PeIN) is currently classified in human papillomavirus (HPV)- and non-HPV-related subtypes with variable HPV genotypes. PeINs are frequently associated with other intraepithelial lesions in the same specimen. The aim of this study was to detect and compare HPV genotypes in PeINs and associated lesions using high-precision laser capture microdissection-polymerase chain reaction and p16INK4a immunostaining. We evaluated resected penile specimens from 8 patients and identified 33 PeINs and 54 associated lesions. The most common subtype was warty PeIN, followed by warty-basaloid and basaloid PeIN. Associated lesions were classical condylomas (17 cases), atypical classical condylomas (2 cases), flat condylomas (9 cases), atypical flat condylomas (6 cases), flat lesions with mild atypia (12 cases), and squamous hyperplasia (8 cases). After a comparison, identical HPV genotypes were found in PeIN and associated lesions in the majority of the patients (7 of 8 patients). HPV16 was the most common genotype present in both PeIN and corresponding associated lesion (50% of the patients). Nonspecific flat lesions with mild atypia, classical condylomas, and atypical condylomas were the type of associated lesions most commonly related to HPV16. Other high-risk HPV genotypes present in PeIN and associated nonspecific flat lesion with mild atypia were HPV35 and HPV39. In this study of HPV in the microenvironment of penile precancerous lesions, we identified identical high-risk HPV genotypes in PeIN and classical, flat, or atypical condylomas and, specially, in nonspecific flat lesions with mild atypia. It is possible that some of these lesions represent hitherto unrecognized precancerous lesions.

Human papillomavirus (HPV) high risk genotype infection and HPV viral load influences the development of invasive cervical cancer and cervical intra-epithelial neoplasia (CIN). HPV DNA testing for screening of cervical cancers may play a potential role in its early detection and management. The present study detected HPV DNA and estimated HPV viral load in different types of cervical lesions among Bangladeshi women. Using the Hybrid Capture 2 (HC2) assay, HPV DNA was tested among 68 women between 25-70 years of age. A total of 13 (19.1%) cases were positive for HPV DNA. The highest viral load (501 x 10³ copies/ml) was detected in a patient with invasive carcinoma, while the lowest viral load (105 x 10³ copies/ml) was detected from a case of chronic cervicitis. The mean viral load in CIN I was 119.25 x 10³±12.5 x 10³ copies/ml (range: 110 x 10³ - 137 x 10³) and 208.50 x 10³ ± 0.59 x 10³ copies/ml (range: 139 x 10³-305 x 10³) in CIN II / III. Interestingly, HPV DNA was detected from a patient with normal cytological findings. Our study observed a moderate presence of high-risk HPV genotypes among women with cervical lesions. The HPV viral load varied with the age of the patients and stage of cervical lesions. The HC2 assay is a promising tool for diagnosing high-risk HPV infection especially before cytology tests show any abnormality.

Abstract Background To investigate distributions of cervical lesions and factors associated with the severity of the cervical lesions in high-risk HPV (hr-HPV) positive women with atypical squamous cells of undetermined significance (ASC-US) cytology. Methods Clinical information of 250,000 women who underwent HPV and cytological test was collected from January 2012 to January 2019. The association between the severity of the cervical lesions and hr-HPV genotypes, hr-HPV viral load, and ages, were analyzed in hr-HPV-positive/ASC-US women. Results 3459 hr-HPV-positive/ASC-US women were enrolled in this study. Overall, 43.51% of women with ASC-US had normal histological results, 34.35% had high-grade squamous intraepithelial lesion (HSIL), and 1.30% had cervical cancer. The rate of HSIL or worse (HSIL+) in women with single HPV16 infection (63.09%) was the highest, followed by HPV33 (57.50%), HPV51 (36.11%), HPV58 (36.11%), HPV52 (28.28%), HPV18 (26.37%), HPV66 (19.35%), HPV39 (18.92%), HPV53 (15.00%), and HPV56 (8.51%). Detection rate of HSIL+ in low, intermediate and high viral-load groups were 15.87% (n = 30), 34.91% (n = 74) and 40.68% (n = 214) (Cochran-Armitage Trend test χ2 = 35.03, p < 0.0001). Compared with the 51–60-year-old group (21.65%), the women in ≤ 30 (40.52%), 31–40 (39.67%), and 41–50 (34.22%) year-old groups had significantly higher risk of HSIL+. The women in ≤ 51–60 (2.68%) and > 60 (3.41%) year-old groups were at increased risk for cervical cancer, compared with the ≤ 30-year-old group (0.61%). Conclusions ASC-US women with HPV 16/18/33/51/52/58 single infection and multiple infections, as well as high HPV viral loads, have high risk of HSIL+.

e14623 Background: Poly-gamma-glutamic acid (γ-PGA), as a signaling regulator of Toll-like receptor 4 (TLR4), has been shown to induce innate immune responses. In previous non-clinical study, we showed that γ-PGA induces signaling pathway of Type 1 interferon, which consequently eliminates various viruses such as SARS, hepatitis C virus, influenza virus, etc. To evaluate the clinical efficacy of γ-PGA, we’ve investigated the antiviral effect of γ-PGA on human. In retrospective study to evaluate, the clinical significance of g-PGA treatment for vaginal intraepithelial neoplasia (VAIN), γ-PGA may be helpful for the cytological regression and reduction of viral load in patients with high-risk HPV-positive VAIN. Since previous human studies showed the possibility of a drug, we have completed a phase I dose escalation study to determine the safety, tolerance and pharmacokinetics of γ-PGA in healthy adult male subjects. Methods: In the current study, we designed a human study of γ-PGA orally treated daily (75 mL) for 24 weeks to demonstrate the antiviral effect of γ-PGA in female HPV-positive patients. HPV viral load and cell-mediated immune responses were measured during 24 weeks to compare HPV clearance rates between the γ-PGA-treated group and the placebo-controlled group and to evaluate immunological parameters, respectively. Results: . In phase IIb clinical trial to evaluate the efficacy and safety of γ-PGA for the fertile women with cervical intraepithelial neoplasia grade 1 (CIN1) patients, regression rate by the treatment of γ-PGA was 45.65%, whereas the placebo controls were 30.23% in ITT group with statistically significance ( p= 0.0247). Conclusions: γ-PGA may be helpful for the cytological regression and reduction of viral load in patients with high-risk HPV-positive CIN I.
