Abstract Verruciform xanthoma (VX) is a rare lesion with a predilection for oral mucosa. Only 16 cases of VX of the penis have been reported. Histologically, VX lesions in different locations are identical; however, the etiology is controversial. Previous studies have reported the presence of human papillomavirus (HPV) in VX of the skin. The purpose of this study was to determine whether HPV is a causative agent in this rare case of VX of the penis. Microscopically, the lesion demonstrated prominent verrucoid squamous hyperplasia with hyperkeratosis, parakeratosis, and acanthosis. Histiocytes, a hallmark of VX, were identified in the elongated dermal papillae. Nested polymerase chain reaction was performed on the DNA with the commonly used primer sets MY9/MY11 and GP5+/GP6+, which identify more than 40 HPV types. The results failed to identify HPV DNA in the sample, although HPV could be readily detected in genomic DNA extracted from paraffin-embedded condyloma acuminatum, a known HPV-associated lesion. Additionally, we tested a VX lesion of the palate for HPV DNA and obtained negative results. Our results indicate that VX can arise without HPV infection and suggest other possible origins may be involved.

AbstractThe aim of this study was to determine the frequency of multiple type human papillomavirus (HPV) infections, and whether any types are involved in multiple HPV-type infections (mHPV) more or less frequently than expected. From January 2012 to February 2018, 2848 cervico-vaginal swabs were analysed in the UOC Microbiology and Virology of Policlinico of Bari, Italy. HPV DNA detection was performed using initially nested-polymerase chain reaction (PCR) and subsequently multiplex real-time PCR assay. 1357/2848 samples (47.65%) were HPV DNA positive and 694/1357 (51.14%) showed mHPVs. The median number of mHPVs was 2 (interquartile range: 2–3). HPV-types more frequently detected were 42 (9.97%), 16 (8.92%), 53 (7.23%) and 31 (7.16%). Each detected HPV-type was involved in mHPVs in more than 50% of cases. Statistical analysis showed significant associations for all HPV-types except for 33, 43, 51, 58 and 82 HPV-types. The major number of significant pairwise associations were detected for the types 42 and 70. Only positive associations were detected. Further data are necessary to evaluate the clinical impact of the single combinations.

The features and clinical course of chronic balanitis in 5 patients are presented. In each case, histological examination of a cutaneous biopsy sample showed pronounced features of human papillomavirus (HPV) infection. In addition, HPV DNA was demonstrated in each biopsy specimen by a polymerase chain reaction and was found to be type 6 by Southern blot hybridization in 4 of the cases. Although the association of histological features of HPV infection with balanitis does not prove that HPV is causal, the failure to find other causes, the prolonged and distressing symptoms, and the ineffectiveness of topical steroids in improving symptoms, all suggest the importance of HPV infection. While effective treatment needs to be sought and developed, the response of one patient to oral isotretinoin suggests that this agent may be appropriate for a larger trial.

Introduction: Human papillomavirus (HPV) is frequently a sexually transmitted virus and can cause cervical cancer in women. Cervical cancer is the second most common type of cancer among the developing countries. In this study, cervical HPV DNA positivity and genotype distributions were investigated in female patients living in our region and the results were compared with different studies. Materials and Methods: Between 1 July, 2017 and 1 March, 2019, 433 cervical swabs were sent to Ataturk University, Medical Faculty Hospital, Medical Microbiology Laboratory due to suspicion of HPV. Swab samples were evaluated for HPV virus using molecular (Polymerase Chain Reaction-PCR) methods. For this purpose, Xpert HPV Test (Cepheid, Inc, Sunnyvale, CA) was used to identify HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 t in a single sample. Results: Mean age of the patients ranged from 20 to 69 years, with a mean of 39.8 years (± 10.0). Positivity was detected in 62 of the 433 patients. Mean age of the positive patients was 40.2 years (± 11.3). When the positive patients were examined in terms of HPV types, the presence of HPV 16 was observed with a rate of 25.6%, while the HPV 18/45 types were found to be 9.0% in total. When patients were evaluated according to age groups, HPV DNA positivity was highest in the 25-34 age group with 38.7%. In our statistical study, there was no significant difference in HPV DNA positivity rate between the ages of 35 and under 35 years. Conclusion: This study demonstrates the prevalence and viral genotype distribution of HPV infection in women in Erzurum region. HPV type 16 is seen with a high rate in our region.

A Prospective Study

The occurrence of human papillomavirus (HPV) among males was analysed with the polymerase chain reaction (PCR) method. Penile brush samples were taken once from 147 males attending for a control or for HPV non-related reasons, and consecutive samples were collected from 88 males re-attending the clinic. Of the males attending once, 13% (19/147) were HPV DNA positive and among the re-attenders 14% (12/88) were initially positive as compared with 33% (29/88) who were positive at least at one visit. Totally, 22 different HPV types were detected of which HPV 16 was most common, found in 6.4% (15/235), followed by HPV 42 found in 3.8% (9/235). Among 14 HPV-positive males with at least one follow-up, 7 had persistent infections with at least one HPV type, and transient HPV types were observed in 9; but in 5 of them new types appeared at follow-up. Among sexually-active males subclinical/latent HPV infection is common and repeated sampling increases its prevalence.

Abstract Context.—Human papillomaviruses (HPVs) play an important role in the etiology of squamous cell carcinoma of the uterine cervix. The possible role of the male urogenital tract as a reservoir of HPV infection is not fully understood. We inferred from our previous observation of HPV-31 in epididymal tissue in a case of chronic epididymitis that HPV might be commonly present in cases of epididymitis caused by sexually transmitted pathogens. Objective.—To assess the presence of HPV in the epididymis and ductus deferens in nontuberculous epididymitis. Design.—Epididymal samples obtained from 17 patients and epididymal and ductus deferens samples from 5 patients surgically treated for nontuberculous epididymitis were analyzed by nested polymerase chain reaction for the presence of HPV DNA. In positive samples, the HPV type was determined by DNA sequencing. Setting.—Tertiary-care academic hospital and national reference laboratory for papillomaviruses. Results.—Low-risk HPV type 6 and high-risk HPV types 16, 33, 35, 55, and 73 were detected in 7 patients (31%). Neither koilocytes nor dysplastic changes were found in the epididymis and ductus deferens. Conclusion.—Low-risk and high-risk HPV types were detected in the epididymis and ductus deferens of patients with nontuberculous epididymitis. The infection was not accompanied by koilocytic atypia or dysplasia. Our findings support the hypothesis that the male urogenital tract serves as a reservoir of HPV infection.

Background. Cardiovascular diseases are leading causes of death worldwide. Recent studies suggest that infection by some viruses, including the human papillomavirus (HPV), may increase the risk of developing atheromatous lesions on coronary arteries. However, there is a lack of data regarding the possible association between HPV infection and coronary artery disease (CAD) in women. Objective. To investigate whether HPV infection is associated with the occurrence of CAD among climacteric women. Methods. The presence of CAD and cervical HPV DNA was investigated in 52 climacteric women. Social and demographic variables and metabolic profiles were also investigated. Results. Among 27 women with CAD, 16 were positive for HPV, whereas 11 were negative. The presence of cervical HPV was strongly associated with CAD, after adjusting for demographic variables, health and sexual behaviors, comorbidities, and known cardiovascular risk factors. HPV-positive women showed a greater likelihood of having CAD (odds ratio [OR] = 3.74; 95% confidence interval [CI]: 1.16 to 11.96) as compared with HPV-negative women, particularly those infected with high-risk HPV types (OR = 4.90; 95% CI: 1.26 to 19.08). Conclusion. These results support the hypothesis that HPV infection might be associated with CAD among climacteric women, though further studies are needed to investigate the mechanisms involved.

We examined 12 recurrent respiratory papillomatosis patients, who were undergoing treatment for recurrence of their disease, for the presence of human papillomavirus (HPV). Biopsies were obtained from their respiratory papillomas and nondiseased sites (NDS) of the respiratory tract: the nasopharynx, posterior tonsillar pillar, aryepiglottic fold, cervical trachea, intrathoracic trachea, and bronchi. The presence of HPV DNA was determined by using the ViraPap/ViraType DNA hybridization procedure. Two thirds of the patients were infected with HPV 6/11 in either the diseased papilloma or NDS: 50% of patients with papilloma specimens typed positive (6 of 12), and 40% of the patients typed HPV-positive in one or more biopsies from the NDS (4 of 10). No single NDS was more likely to be infected with HPV than any other. No oncogenic HPV types 16/18 or 31/33/35 were detected in the papillomas or NDS of these patients. Only patients with multiple, and not isolated, papilloma involvement were found to harbor HPV DNA in NDS; and 80 % of those with infected NDS, compared to 20 % of those without infected NDS, required a shorter (no more than 3 months) surgical treatment interval. Our results show that HPV infection frequently persists in adjacent, clinically normal sites, and suggest that the extent of NDS involvement may predict both the extent of disease and the likelihood of recurrence.

The Impact

The impact of human papillomavirus (HPV) infection on pregnancy is a major problem of medicine. The transmission of the virus from mother to fetus is a process yet unresolved. The immune response and changed hormonal status of pregnant women might facilitate infection. A research on the prevalence of HPV infection was conducted at the Clinic of Obstetrics, Medical University of Lublin (Poland). The studied group included 152 randomly selected women. The material was tested for the presence of HPV DNA by means of polymerase chain reaction (PCR). The aim of the research was to assess the relation between HPV infections detected in the buccal smears of the neonates and the incidence of such infections in the cervical/buccal smears of their mothers. In the group of 152 infants HPV was found in 16 (10.53%). Among the cervical/buccal smears, HPV was isolated, respectively, in 24 (15.79%) and in 19 (12.5%) pregnant women. Statistically significant differences in the prevalence of HPV swabs from the newborns and the cervical/buccal smears of their mothers were found (p< 0.001). The identification of mothers in whose buccal smears HPV was detected can help develop a group of children who run a relatively significant risk of being infected.

Papillomavirus Infection

In order to determine the prevalence and genotype distribution of human papillomavirus (HPV) infection in patients with nasal polyps, a total of 204 patients with nasal polyps and 36 healthy controls were recruited for this study. Genomic DNA was extracted from paraffin-embedded tissue sections. HPV DNA genotyping was achieved by a flow-through hybridization and gene-chip method. HPV-positive infection was identified in 82 of 204 (40.2 %) patients, while HPV DNA was not found in healthy controls (P<0.05). Genotyping analysis showed that low-risk HPV genotype 11 was the most prevalent type of HPV in nasal polyps (45.28 %). Both single and multiple HPV genotype infections were found in these HPV-positive cases, although most (74.39 %) were infected with a single genotype. In addition, there was no correlation between HPV infection or HPV subtypes and the clinicopathological characteristics of patients, such as age, gender, number of surgery and disease course. The data from our study clearly demonstrated that HPV infection was associated with nasal polyps. Both high-risk HPV and low-risk HPV (LR-HPV) genotypes were identified in nasal polyp tissues, and LR-HPV-11 was the most prevalent type. Future research will explore the association of HPV infection with the development and progression of nasal polyps.

The risk of high-grade lesions and carcinoma is known to correlate with specific high-risk HPV genotypes. The distribution of HPV types varies between countries and little is known about HPV distribution in our country. Therefore, the purpose of this study was to determine the range and frequency of HPV genotypes in studied group of women in Montenegro. HPV genotypes were determined using the method of enzyme restriction of PCR products amplified with group-specific primers MY09/MY11 and restricted with seven different restriction endonucleases. Out of the total number of women HPV infection was found in 1/5 of participants (20%). Genotyping performed in HPV DNA positive women shows that the HPV genotype 16 is dominant and present in more than 1/3 of the participants (36.8%). The second most frequent HPV infection is with HPV genotype 58 and it is found in 10.5% of participants. HPV 31 and HPV 6 infections are present in 7.9% of women, while infections with other genotypes were demonstrated individually by 2.6%. Multiple HPV infection was demonstrated in 18.4% and they are dominant in younger women (aged 25 to 30 years).
