Abstract
Genetic variation in the transmembrane channel-like (TMC)6/TMC8 region has been linked to β-type human papillomavirus (HPV) infection and squamous cell carcinoma (SCC) of the skin and the head and neck, α-type HPV persistence and progression to cervical cancer. The functional variant rs7208422 of the TMC8 gene was suggested to have a high impact on susceptibility to β-papillomaviruses and their oncogenic potential and to also have an influence on α-type HPV-related disease. The aim of the present study was to evaluate a possible influence of rs7208422 on penile cancer risk, a known α-type HPV-related malignancy. Therefore, the distribution of rs7208422 was determined by direct Sanger sequencing of 104 Caucasian penile SCC cases and compared to data of 3,810 controls taken from the literature. HPV detection was performed by usage of GP5+/6+ primers and subtype-specific PCR. It was observed that the distribution of rs7208422 followed the Hardy-Weinberg equilibrium in both cases and controls. HPV DNA was detected in 39% of the penile SCC cases. Overall, there was no significant difference in the distribution of rs7208422 neither between cases and controls (P=0.726) nor between HPV-positive and -negative penile SCC cases (P=0.747). There was also no association between rs7208422 genotypes and age of disease onset (P=0.740). In conclusion, the present data argue against a significant impact of rs7208422 on the risk for the development of penile SCC in Caucasians. Even in combination with the HPV status, the SNP appears not to influence the risk of penile SCC in HPV-positive cases.

Simultaneous Detection and Viral DNA Load Quantification of Different Human Papillomavirus Types in Clinical Specimens by the High Analytical Droplet Digital PCR Method. Front Microbiol 2020; 11:591452. [PMID: 33329471 PMCID: PMC7710522 DOI: 10.3389/fmicb.2020.591452] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Accepted: 10/19/2020] [Indexed: 12/31/2022] Open
Abstract
Human papillomaviruses (HPVs) are small DNA tumor viruses that mainly infect mucosal epithelia of anogenital and upper respiratory tracts. There has been progressive demand for more analytical assays for HPV DNA quantification. A novel droplet digital PCR (ddPCR) method was developed to simultaneously detect and quantify HPV DNA from different HPV types. DdPCR was initially tested for assay sensitivity, accuracy, specificity as well as intra- and inter-run assay variation employing four recombinant plasmids containing HPV16, HPV18, HPV11, and HPV45 DNAs. The assay was extended to investigate/quantify HPV DNA in Cervical Intraepithelial Neoplasia (CIN, n = 45) specimens and human cell lines (n = 4). DdPCR and qPCR data from clinical samples were compared. The assay showed high accuracy, sensitivity and specificity, with low intra-/inter- run variations, in detecting/quantifying HPV16/18/11/45 DNAs. HPV DNA was detected in 51.1% (23/45) CIN DNA samples by ddPCR, whereas 40% (18/45) CIN tested HPV-positive by qPCR. Five CIN, tested positive by ddPCR, were found to be negative by qPCR. In CIN specimens, the mean HPV DNA loads determined by ddPCR were 3.81 copy/cell (range 0.002-51.02 copy/cell), whereas 8.04 copy/cell (range 0.003-78.73 copy/cell) by qPCR. DdPCR and qPCR concordantly detected HPV DNA in SiHa, CaSki and Hela cells, whereas HaCaT tested HPV-negative. The correlation between HPV DNA loads simultaneously detected by ddPCR/qPCR in CINs/cell lines was good (R 2 = 0.9706, p < 0.0001). Our data indicate that ddPCR is a valuable technique in quantifying HPV DNA load in CIN specimens and human cell lines, thereby improving clinical applications, such as patient management after primary diagnosis of HPV-related lesions with HPV-type specific assays.

Abstract
Viral infections are considered to be risk factors for spontaneous abortion (SA). Conflicting results have been reported on the association between Human Papillomavirus (HPV) and SA. HPV DNA was investigated in matched chorionic villi tissues and peripheral blood mononuclear cells (PBMCs) from women who experienced SA (n = 80, cases) and women who underwent a voluntary interruption of pregnancy (VI; n = 80, controls) by qualitative PCR and quantitative droplet digital PCR (ddPCR). Viral genotyping was performed using real-time PCR in HPV-positive samples. Specific IgG antibodies against HPV16 were investigated in sera from SA (n = 80) and VI (n = 80) females using indirect ELISA assays. None of the DNA samples from SA subjects was HPV-positive (0/80), whilst HPV DNA was detected in 2.5% of VI women (p > 0.05), with a mean viral DNA load of 7.12 copy/cell. VI samples (n = 2) were found to be positive for the HPV45 genotype. The ddPCR assay revealed a higher number of HPV-positive samples. HPV DNA was detected in 3.7% and 5% of SA and VI chorionic tissues, respectively, with mean viral DNA loads of 0.13 copy/cell in SA and 1.79 copy/cell in VI (p >0.05) samples. All DNA samples from the PBMCs of SA and VI females tested HPV-negative by both PCR and ddPCR. The overall prevalence of serum anti-HPV16 IgG antibodies was 37.5% in SA and 30% in VI (p > 0.05) women. For the first time, HPV DNA was detected and quantitatively analyzed using ddPCR in chorionic villi tissues and PBMCs from SA and VI women. Circulating IgG antibodies against HPV16 were detected in sera from SA and VI females. Our results suggest that HPV infection in chorionic villi may be a rare event. Accordingly, it is likely that HPV has no significant role in SA.

Abstract
The genital colonization of certain Mycoplasma and Ureaplasma spp. has been associated with an increased the risk of acquisition and persistence of human papillomavirus. However, its association with high-risk human papillomavirus genotypes is not entirely clear, and the prevalence of such coinfections in cervical precancerous lesions has been poorly explored. Therefore, the aim of this study was to investigate the association of high-risk human papillomavirus with Mycoplasma and Ureaplasma spp. in 258 women recruited during their routine gynecological inspection at an outpatient clinic in Tabasco, Mexico. Among the Mycoplasma and Ureaplasma spp. evaluated in the present study, the highest peak of prevalence was attributed to Ureaplasma parvum (32.9%), followed by Mycoplasma hominis (14%), Ureaplasma urealyticum (6.6%), and Mycoplasma genitalium (0.8%). The overall prevalence rates of papillomavirus DNA and high-risk human papillomavirus were 25.6% and 17.1%, respectively. The overall association showed that M. hominis and U. urealyticum correlated significantly with high-risk human papillomavirus infection. According to the cytological results, the distribution of coinfection with high-risk human papillomavirus and U. urealyticum did not show significant differences with respect to severity of cervical lesions. Conversely, the association of high-risk human papillomavirus with M. hominis was more frequent in women with high-grade squamous intraepithelial lesions ( P = 0.037).

Abstract
Squamous cell carcinoma of the penis is a rare but often aggressive disease. A large proportion of penile cancers are associated with HPV infection, mainly with HPV high-risk subtypes 16 and 18. From other HPV-related malignancies a link between a functional SNP in the p53 gene (rs1042522, p.Arg72Pro) and a higher disease risk in the presence of HPV is documented. The p53 p.Arg72 variant was described as a risk factor for developing a malignancy in combination with the presence of HPV as the p.72Arg variant is more prone to HPV E6 protein-mediated degradation than the p.72Pro variant. For penile carcinoma there are only sparse data available on this topic. We therefore analyzed the distribution of this p53 codon 72 SNP in a cohort of 107 penile cancer patients and a healthy control group (n=194) using Restriction Fragment Length Polymorphism (RFLP) analysis. After DNA isolation a PCR amplicon including the variant nucleotide was generated. Based on the variant nucleotide this amplicon can be cleaved into two parts or remain unaffected by a restriction enzyme. Subsequent electrophoresis allowed the discrimination of SNP alleles in the investigated sample. Comparison of the allelic variants revealed no significant differences in the distribution of this SNP between cases and controls (p=0,622). There was also no difference in SNP distribution between cases with/without HPV infection (p=0,558) or histologic variants (p=0.339). In order to strengthen the impact of our data we performed a combined analysis of all published data on this topic with our results. This ended up in SNP distribution data from 177 cases and 1149 controls. Overall, there were also no significant differences in the allelic distribution of the p53 codon 72 SNP between either cases and controls (p=0,914) or HPV-positive and HPV-negative cases (p=0,486). From this most comprehensive data available to date we conclude that there is no influence of the p53 codon 72 SNP on the risk of development of penile carcinoma in Caucasians even in the presence of HPV.

Abstract
Background In the present study we retrospectively evaluated the results of outpatients who had an HPV analysis, and present objective evidence for the administration of preventive inoculation in our area. Material/Methods We retrospectively reviewed 532 outpatients who visited a single center between 2012 and 2016 and had an HPV infection analysis. The criteria for inclusion of patients with unhealthy cervix in the study were: erosion, chronic cervicitis, healed lacerations, hypertrophied cervix, and abnormal discharges from the cervix. Results We found that 122 out of 532 patients were infected with HPV, and the rate of multiple infections was 59.0% (72/122). HR-HPV (group 1 carcinogens HPV-16 (18.9%, 23/122), HPV-18 (13.1%, 16/122), HPV- 31 (4.9%, 6/122), HPV-33 (3.3%, 4/122), HPV-35 (7.4.9%/122), HPV-39 (5.7%, 7/122), HPV-45 (5.7%, 7/122), HPV-51 (11.5%, 15/122); Group 3 LR-HPV; HPV-6 (31.1%, 38/122), HPV-11 (26.2%, 32/122), HPV-42 (9.0%, 11/122) and HPV-43 (4.9%, 6/122). In terms of linear-by-linear association test, no significant statistical difference was identified between years. The P value for HPV infection rate on year basis was P>0.05. Conclusions In this hospital-based retrospective analysis, HPV types were found to be similar to HPV types reported in developed countries. We firmly suggest that patients should be informed about the risk of HPV infection at early ages.

Abstract
BACKGROUND Infection with certain human papillomavirus (HPV) genotypes is the most important risk factor related with cervical cancer. The objective of the present study was to investigate the prevalence of HPV infection, the distribution of HPV genotypes and HPV E6/E7 oncogene mRNA expression in Turkish women with different cervical cytological findings in Mersin province, Southern Turkey. MATERIALS AND METHODS A total of 476 cytological samples belonging to women with normal and abnormal cervical Pap smears were enrolled in the study. For the detection and genotyping assay, a PCR/direct cycle sequencing approach was used. E6/E7 mRNA expression of HPV-16, 18, 31, 33, and 45 was determined by type-specific real-time NASBA assay (NucliSENS EasyQ(®)HPV v1.1). RESULTS Of the 476 samples, 106 (22.3%) were found to be positive for HPV DNA by PCR. The presence of HPV was significantly more common (p<0.001) in HSIL (6/8, 75%) when compared with LSIL (6/14, 42.9%), ASC-US (22/74, 29.7%) and normal cytology (72/380, 18.9%). The most prevalent genotypes were, in descending order of frequency, HPV genotype 66 (22.6%), 16 (20.8%), 6 (14.2%), 31 (11.3%), 53 (5.7%), and 83 (4.7%). HPV E6/E7 oncogene mRNA positivity (12/476, 2.5%) was lower than DNA positivity (38/476, 7.9%). CONCLUSIONS Our data present a wide distribution of HPV genotypes in the analyzed population. HPV genotypes 66, 16, 6, 31, 53 and 83 were the predominant types and most of them were potential carcinogenic types. Because of the differences between HPV E6/E7 mRNA and DNA positivity, further studies are required to test the role of mRNA testing in the triage of women with abnormal cervical cytology or follow up of HPV DNA positive and cytology negative. These epidemiological data will be important to determine the future impact of vaccination on HPV infected women in our region.

Abstract
BACKGROUND Cytomegalovirus (CMV) infections are the leading cause of infectious hearing loss and central nervous system disease among children worldwide. In this study, we aimed to determine the birth prevalence of congenital CMV infection in live-born infants in Turkey. METHODS In total, 944 consecutive live-born infants born from 926 pregnant women were included in this study. CMV-DNA was investigated in saliva samples of all newborns within the first 3 days after birth using TaqMan-based real-time PCR. RESULTS The birth prevalence of congenital CMV infection in live-born infants was 1.91% (18/944), and all congenitally infected infants were asymptomatic at birth. The prevalence of congenital CMV infection was 16.7% (3/18) in twin pregnancies and 1.32% (12/908) in single pregnancies (p = 0.002). Genotyping analysis showed glycoprotein B-1 (gB1) to be the most frequently detected genotype at 83.3%. CONCLUSION The study results suggest that the majority of congenital CMV infection in Turkey occurs following nonprimary maternal infection. We believe that congenital CMV infection and its long-term effects have been underestimated in our country, as infected infants are usually asymptomatic at birth.
