Abstract Background The potential HPV transmission route includes horizontal transmission “in utero” and vertical transmission from parents. Less is known about the role of child’s father as a potential source of HPV infection and involved in the pathogen’s epidemic chain. A possible consequence of perinatal infection includes HPV-related childhood diseases and carrying the risk of cervical cancer development in female offspring. In view of the evidence, studies of HPV co-occurrence in one or both parents and their offspring seem vital for the implementation of respective preventive measures. Consequently, the aim of this study was to determine the incidence of common HPV 16/18 infections in newborns and their parents, and to assess its role of the periconceptional transmission. Methods To determine the incidence of common HPV infections in newborns from single pregnancies and their parents. The study included 146 pregnant women, as well as their partners, and newborns. They were tested for the presence of HPV 16/18 DNA using the PCR method. HPV types 16 and/or 18 were identified using type-specific PCR primers. The quality of the extracted DNA was evaluated by PCR using PC03/PC04 β-globin-specific primers. The relationship between the presence of neonatal and parental HPV infection was analyzed using a multivariable regression model. Calculations were carried out with the Statistica 10. Results The presence of HPV DNA was detected in 19 (13,01%) newborns, 28 (19,18%) mothers, and 20 (13,7%) fathers. The viral DNA was detected in 14 newborns delivered by HPV-positive mothers (OR = 26,08; CI: 8,07-84,31, p < 0.001), 12 descendants of HPV-positive fathers (OR = 22,13; CI: 6,97-70,27, p < 0.001), and 10 children originating from two infected parents (OR = 24,20; CI: 6,84–85,57 p < 0.001). Those findings points to a increase risk of an acquired infection in newborns with HPV-positive parents. Conclusion Our findings suggest the possible role of the periconceptional transmission in the mode of acquired HPV 16/18 infections.

Abstract Background Human Papillomavirus (HPV) infection is one of the most important causes of cancer. It can play a role in cervical and extra-cervical cancers. Penile cancer is rare, even if an increasing trend was recently reported. Aim of the present study was to assess the prevalence and distribution of HPV genotypes in cases of penile cancer diagnosed in Sardinia, Italy. Surrogate markers of HPV infection (i.e., E6 and p16 genes) were also evaluated in all cases. Methods An observational, retrospective study which recruited all cases of penile cancer diagnosed between 2002 and 2019 at a tertiary care hospital in Sardinia, Italy, was carried out. HPV-DNA detection and genotyping were performed by Real-time PCR. Specimens were tested for oncogene E6 mRNA and for p16(INK4a) expression. Results HPV prevalence was 28.1% (9/32); HPV-16 was the most prevalent genotype (7/9, 77.8%). p16INK4a positivity was found in 66.7% of the samples with a statistically significant difference between HPV-positive and -negative groups. E6-transcript was detected in 71% of the HPV-16 positive samples. The overall survival was not statistically different between HPV-positives and -negatives. Discussion The present study confirms the etiologic role of HPV in penile cancer and supports the adoption of vaccination strategies in men and women. Further studies should clarify the diagnostic and prognostic role of E6 and p16 proteins. Conclusion HPV infection can favor the occurrence of penile cancer, whose diagnosis and prognosis could be improved with the implementation of validated molecular techniques.

AbstractThis study evaluated human papillomavirus’s (HPV) role in pterygium pathogenesis, its autoinoculation from genitalia to ocular surface, potential cytokines involved, and crosstalk cytokines between pterygium and dry eye (DE). This cross-sectional study enrolled 25 healthy controls (HCs) and 116 pterygium patients. Four subgroups of pterygium and DE were used in cytokine evaluations. Conjunctival and pterygium swabs and first-void urine samples (i.e., genitalia samples) were collected for HPV DNA detection using real-time polymerase chain reaction. Tear cytokines interleukin (IL)-6, IL-18, and vascular endothelial growth factor (VEGF) in tears were evaluated. No HPV DNA was detected in conjunctival or pterygium swabs. No association was found between HPV DNA in urine samples and that from conjunctival or pterygium swabs. Tear VEGF levels were significantly higher in pterygium patients than in HCs, with no markedly different levels between primary and recurrent pterygia. Tear IL-6, IL-18, and tear VEGF were significantly higher in participants with DE, regardless of pterygium status. In conclusion, HPV infection was not a pathogenic factor of pterygia. The hypothesis of HPV transmitting from the genitals to ocular surfaces was nullified. Tear VEGF was involved in both pterygia and DE, whereas tear IL-6 and IL-18 played roles only in DE.

ABSTRACT: Introduction: Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

Various risk factors have been implicated in the causation of cervical cancer including human papillomavirus (HPV), the early genes (E6 and E7) of which encode the main transforming proteins. Studies have suggested that steroid hormones may enhance the expression of these genes leading to loss of p53 gene-mediated cell apoptosis. A total of 120 cervical tissue samples were obtained from patients with proven cervical cancer. Patients who used depo-medroxyprogesterone acetate steroid contraception were recruited as part of the steroid arm. Only HPV DNA type 16 samples were used for the study. Controls included three cell lines (CaSki, SiHa, & C33A) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as an internal housekeeping gene. Of 120 patients, there were 111 patients with HPV type 16 identified. Of this number, RNA was present in 63 samples. There were 30 women (30/63) who used steroid contraception. In relation to patients who used contraception, HPV 16 E6 gene expression was present in 79% (n = 23) and 88% (n = 30) of steroid users compared to nonusers, respectively. In total there were 25 patients (40%) with expression of the HPV 16 E6*I gene and 30 patients with expression of the E6*II gene. There were 57% of steroid users (n = 17) who had expression of the E6*I/E6*II gene, compared to 52% (n = 17) of nonusers (P = 0.800). From a molecular level, this study does not confirm the role of injectable progesterones in cervical carcinogenesis.

AbstractCervical cancer morbidity and mortality in Lithuania is one of the biggest in the European Union. The main risk factor of cervical cancer is human papillomavirus (HPV). The deletion of the HPV E2 gene influences HPV DNA integration into the cell genome, as well as a rapid progression of cervical lesions. The purpose of this study is to determine HPV, its types, and HPV 16 integration in different grades of cervical intraepithelial neoplasias (CIN). 253 women with cytological lesions were involved in the study. After a histology, 31 women were diagnosed with CIN I, 35 with CIN II, and 51 with CIN III. The biggest prevalence of HPV infection was detected in women younger than 25 years old (69.7%) and in women with CIN II (90.9%). HPV 16 was detected in 67.8% of all cases, with the highest prevalence in CIN III (84.4%). A partial integration form was detected in 65.0% of HPV 16 infected women, a complete virus integration in 26.5%, and an episomal form in 8.4% of cases. Our study concludes that in all the cases confirmed using a histology, the partial virus integration form of CIN was identified the most. It was less frequently detected in CIN I cases (60.0%), but more frequently in CIN II and CIN III cases (72.8 and 69.3%, respectively).

Abstract Background : Some studies in the literature suggest a possible role of multiple HPV infections as a prognostic factor in the development and progression of cervical neoplasia. we studied the cases of single and multiple HPV infection and analyzed the correlation with negative cases, and preneoplastic and neoplastic lesions of the uterine cervix with the aim of making a contribution to the prognostic factor under discussion Methods: 921 women with clinical HPV manifestations were enrolled. Inclusion criteria were: positive at the cytology for HPV lesions, presence of preneoplastic and neoplastic lesions of the uterine cervix diagnosed by the histology examination All the patients underwent colposcopy and cervical biopsy with viral genotyping. The search for viral DNA was carried out using polymerase chain reaction. Genotype 16 is correlated with the majority of CIN2+; we divided the multiple HPV16 infections into “infections with 16 as the first genotype” (16mHPV) (e.g. HPV 16 , 31, 52) and into “ infections containing 16” (m16HPV) (e.g. HPV 31, 16 , 52), we then divided them based on the number of genotypes present: infections with 2 strains, 3 strains, 4 strains, and > 4 strains. Results: We analyzed the differences between single and multiple infections with HPV16, the patients with single infections had a higher incidence of CIN2+ (83.3%) with respect to those with multiple infections (71.4%). The 16mHPV infection was significative for CIN2/CIN3. When the prevalence of the combinations between the genotypes was studied, we found that in 16mHPV infection HPV16, 18 and HPV 16, 31 were the most common combinations of mHPV infection (50%) and the most frequent in CIN2/CIN3 The 16mHPV infection with 2 genotypes, with respect to the infections with 3 or more genotypes, was significative with an OR= 7.94 (IC% 2.55-24.73). Conclusions: Our results suggest that single HPV infections give a higher risk of SCC development with respect to multiple HPV infections. Among multiple infections, only 16mHPV infection with 2 genotypes is associated with CIN2/CIN3 in a significative way and it presents an 8 times greater risk of developing a high grade lesion.

Background: In addition to smoking and alcohol consumption, human papillomavirus (HPV) is a leading etiology for Head and Neck Squamous Cell Carcinoma (HNSCC). However, this causal association is still understudied in Middle Eastern populations. Objective: The aim of this study was to determine the prevalence of HPV-associated infection in the Jordanian HNSCC patients and the associated HPV genotypes. Methods: Formalin-Fixed Paraffin-Embedded (FFPE) squamous cell carcinoma samples of the head and neck were collected from two referral centers in Amman, Jordan to determine the existence of HPV DNA. After DNA extraction HPV infection and genotyping were identified using real-time PCR. Results: HPV DNA was detected in 19 out of 61 (31.1%) HNSCC samples. Despite screening for 28 different genotypes, HPV 16 was the only genotype identified in all examined samples. Most HPV-positive samples were obtained from the oropharynx (41.7%), oral cavity (37%), and larynx (18.2%). No significant association between HPV 16 genotype and age, sex, tobacco use, anatomical location, or tumor grade was noticed. Conclusion: This study reported a high association between HPV 16 genotype and HNSCC in Jordanian patients. These data should facilitate the implementation of appropriate HPV awareness campaigns, and activate selective prophylactic measures against HPV infection.

The objective of current study is to evaluate the role of HPV-16 in the pathogenesis of oral epithelial dysplasias (OED) and oral squamous cell carcinoma (OSCC) by immunohistochemistry (IHC) and to know whether HPV-16 participates in disruption of the regulation of p16 INK4A suppressor protein in OED and OSCC by IHC. Histopathologically diagnosed 20 cases of OED and 20 cases of OSCC were selected from amongst the patients attending the OPD of Vasantdada Patil Dental College and Hospital, Sangli. Biopsy tissue section were then tested for HPV-16 by IHC. HPV-16 positive tissue sections were then again tested by p16 by IHC. Overall 22.5% of cases in our study were found to be positive for HPV 16 which includes 10% of cases of OED and 35% cases of OSCC. Amongst the HPV 16 positive cases, more than 60% of cells were positive for p16INK4A IHC in OED (50%) and OSCC (85.71%). Thus, HPV 16 participates in disruption of the regulation of p16INK4A suppressor protein and can be used as surrogate biomarker for detection of HPV infection in OED and OSCC.

Abstract Oral Cancer; especially Oral Squamous Cell Carcinoma (OSCC) is the eighth most common cancer all over the globe and most common neoplasm in India. Due to the tobacco addiction pattern in Indians specially Guajarati’s are well known for high consumption of tobacco in non-smoking form may have the high-risk for developing oral cancer. Apart of this, Human papilloma virus(HPV) might be one of the cause for developing oral cancer hence, the proposed study was carried out for 50 primary OSCC subjects from January 2018 to October 2018. Tumour specimens were HPV-genotyped by type specific PCR method. Statistical analyses were performed by Fisher’s exact test. The present study identified 4% HPV infection frequency in advanced staged OSCC Indian subset, where One OSCC stage IV patient observed with HPV 16 infection and one OSCC stage III patient with HPV 18. Our finding differs with rest of the population, as the region have high amount of consumption of tobacco. Current study need to be validated in larger sample size to get the clear view for association of HPV with oral cancer.
