Association between Human Papillomavirus and Chlamydia trachomatis genital infections in male partners of infertile couples.

The prevalence of HPV infection and its relationship with other sexually transmitted infections was analyzed in a cohort of 117 male partners of infertile couples from Cordoba, Argentina. Semen samples and urethral swabs were obtained and the infection with HPV, Chlamydia trachomatis, HSV1, HSV2, Mycoplasma hominis and Ureaplasma urealyticum was analyzed. A prevalence of HPV infection of 27.4% was found. Interestingly, infections by exclusively low risk HPV genotypes or high/intermediate risk HPV genotypes were present in 64.5% and 22.6% of cases, respectively. Low risk-HPV6 was the most frequently detected genotype. Remarkably, HPV and C. trachomatis infections were significantly associated to each other (OR: 11.55, 95% CI 1.14-117.06). No significant differences in sperm quality were found between HPV-positive and HPV-negative patients indicating that HPV male urogenital infection does not impair sperm quality. Our results show a high prevalence of HPV urogenital infection among male partners of infertile couples, and that HPV and C. trachomatis infections are reciprocal risk factors of their co-infection. Moreover, our results suggest that men constitute a reservoir for continued transmission of C. trachomatis and HPV to women highlighting the need for routine screening for these two pathogens in male partners of infertile couples.

In vivo and ex vivo dermoscopy of lesions from implantation of human papillomavirus in tattoos: report of two cases

Abstract The number of individuals with tattoos has been increasing worldwide, alongside with reports of complications varying from reactions to the injected pigments to infections caused by agents inoculated in the pigmentation process. The diagnosis of such unwanted events can be obtained through complementary non-invasive methods, preserving the maximum of the tattoo design. The authors present two cases of patients with warts on tattooing, and correlate their clinical aspects to in vivo and ex vivo dermoscopy, and to the findings in the histopathological examination, aiming to determine patterns that aid the diagnosis of these lesions without performing biopsy.

Burden of genital warts in Colombia: an observational study / Carga das verrugas genitais na Colômbia: um estudo observacional

Introduction: Genital warts are benign lesions caused by sexual transmission of human papillomavirus types 6 and 11, with significant impact on healthcare resource use and patients' quality of life. Objective: To describe the epidemiology of genital warts in adults visiting a physician office for any reason, physician practice patterns, and healthcare resource use and costs in Colombia. Methods: Participants were a convenience sample of 53 physicians in 5 specialties: primary care (15), gynecology (24), urology (12), proctology (1), and dermatology (1). Physicians completed a survey and daily log of all patients 18-60 years old seen over 10 days in their practices in 2016-2017. The physician survey recorded genital warts consultation and management patterns. The daily log recorded patient demographic information and genital warts diagnosis. Results: Among 6,393 patients logged by physicians, the genital warts prevalence was 2.03% (95%CI 1.69­2.38) and incidence 1.30% (95%CI 1.02­1.58). Primary care physicians referred most of their genital warts cases for treatment (female: mean 63.3%, SD=44.8; male: mean 58.3%, SD=43.8). Treatment of non-resistant episodes (<6-month duration) lasted an average of 37.4 days (SD=29.4) and required an average of 4.0 (SD=1.9) office visits for females and 3.0 (SD=1.7) for males. The overall mean cost of an episode of care was USD558.13 (SD=507.30). Conclusion: Genital warts cases reported by most participant physicians were mainly direct-consult, but patients were typically treated by specialists. Much of the genital warts health care utilization and costs reported could be prevented by immunization with the quadrivalent or nonavalent HPV vaccine.

Introdução: As verrugas genitais são lesões benignas, de transmissão sexual, causadas pelo papilomavírus humano tipos 6 e 11 e que causam impacto significativo no uso de recursos de saúde e na qualidade de vida dos pacientes. Objetivo: Descrever a epidemiologia das verrugas genitais em adultos que buscaram atendimento médico ambulatorial por qualquer motivo, incluindo padrões de prática médica, uso de recursos de saúde e custos na Colômbia. Métodos: foi utilizada uma amostra de conveniência composta por 53 médicos em 5 especialidades: clínico geral (15), ginecologia (24), urologia (12), proctologia (1) e dermatologia (1). Os médicos completaram um questionário e registros diários de todos os pacientes com idade entre 18 e 60 anos atendidos durante 10 dias em seus consultórios em 2016-2017. O questionário registrou os padrões de prática médica e de tratamento de verrugas genitais. Os registros diários continham informações demográficas do paciente e o diagnóstico de verrugas genitais. Resultados: Entre 6.393 atendimentos médicos, a prevalência das verrugas genitais foi de 2,03% (IC95% 1,69­2,38) e a incidência de 1,30% (IC95% 1,02­1,58). Os clínicos gerais encaminharam a maioria dos pacientes com verrugas genitais para tratamento (mulheres: média de 63,3%, DP=44,8; homens: média de 58,3%, DP=43,8). O tratamento dos casos não-persistentes (<6 meses de duração) durou em média 37,4 dias (DP=29,4) e requereu uma média de 4,0 (DP=1,9) consultas para mulheres e 3,0 (DP=1,7) para homens. O custo médio geral do tratamento foi de US$ 558,13 (SD=507,30). Conclusão: Os casos de verrugas genitais relatados pela maioria dos médicos participantes derivaram-se principalmente de atendimentos primários e os pacientes foram tratados geralmente por especialistas. Grande parte da utilização de recursos e custos relacionados a verrugas genitais poderia ser evitada pela imunização com a vacina papilomavírus humano 4-valente ou 9-valente.

Clinicopathological characteristics and papillomavirus types in cutaneous warts in bovine.

Thirty-one bovine cutaneous warts were submitted to macroscopic and histological analyses and to molecular analyses to partial amplification and sequencing of the L1 gene of bovine papillomavirus (BPV). Viral types detected were BPV1 (52%), BPV2 (29%), BPV6 (16%) and BPV10 (3%). BPV2 had lower frequency in papilloma in comparison to that in fibropapilloma (p = 0.002).

Genetic characterization of a putative new type of bovine papillomavirus in the Xipapillomavirus 1 species in a Brazilian dairy herd.

Currently, bovine papillomavirus types are divided into five genera, namely, Deltapapillomavirus, Epsilonpapillomavirus, Xipapillomavirus, Dyoxipapillomavirus, and Dyokappapapillomavirus. In the recent decades, the characterization of numerous putative and novel bovine papillomavirus types from cattle in several geographic regions, has revealed the occurrence of a high viral diversity. In this study, we describe the identification and characterization of a putative new bovine papillomavirus type within species Xipapillomavirus 1 of Xipapillomavirus genus. The detection of the viral types identified in the skin warts was obtained by polymerase chain reaction assays targeting the L1 gene, followed by direct sequencing of the generated amplicons. The partial L1 sequences revealed that bovine papillomavirus types 6, 10, and 11, the putative new bovine papillomavirus type designated BPV/CHI-SW2, and an unreported putative new bovine papillomavirus type (named BPV/BR-UEL08) were associated with cutaneous papillomatosis in the cows from the dairy herd investigated. Phylogenetic reconstruction based on the L1 gene revealed that the BPV/BR-UEL08 isolate clustered with other bovine papillomaviruses classified in the Xipapillomavirus genus, being closely related to representatives of the species Xipapillomavirus 1. Investigations focusing on the molecular epidemiology of bovine papillomaviruses related to clinical outcomes in cattle are of fundamental importance to determine the actual genetic diversity and prevalent viral types to be included in vaccines for cattle.

Molecular characterization of Canis familiaris oral papillomavirus 1 identified in naturally infected dogs from Northeast Brazil.

BACKGROUND: Canine papillomavirus (CPV) has 20 described types associated with papillomas or squamous cell carcinoma (SCC). Knowledge about CPV diversity is scarce. Studies on papillomaviruses that infect other hosts show substantial diversity with some types and variants being associated with cancer. HYPOTHESIS/OBJECTIVES: The aim of this study was to assess the genetic variability of the capsid L1 gene of CPV identified in lesions of naturally infected dogs from Brazil. ANIMALS: Six dogs presenting with oral and cutaneous warts from different veterinary clinics in Sergipe state, Northeast Brazil. METHODS AND MATERIALS: Nine skin biopsy samples were collected for histopathological and molecular analyses. Bioinformatics tools were used for genotyping and diversity analysis. Mutations were characterized based on their impact on the L1 protein structure. RESULTS: Sequences of CPV1 were obtained from exophytic papillomas. These sequences had at least five different mutations showing that all sequences were putative CPV1 variants. One CPV1 sequence, obtained from an oral SCC, had a highly destabilizing substitution in the L1 protein which was likely to be associated with changes in protein function. CONCLUSIONS AND CLINICAL IMPORTANCE: Despite the small number of cases analysed and the partial analysis of L1 nucleotide and amino acid sequences, this study has demonstrated diversity in CPV samples from Northeast Brazil. A putative new CPV1 variant associated with oral SCC, with novel protein structure changing mutations, was identified which may be important for understanding papillomavirus pathogenesis.

First detection of bovine papillomavirus type 2 in cutaneous wart lesions from ovines.

This study diagnosed cutaneous wart lesions excised from three rams from a sheep farm in São Paulo State, Brazil. Histopathologically, these cases were diagnosed as papilloma. The amplification by PCR, sequencing and bioinformatics analysis showed that all the lesions presented DNA sequences of bovine papillomavirus type 2. This is the first report confirming the detection of BPV2 in papilloma warts from ovines.

Detection and phylogenetic analysis of bovine papillomavirus in cutaneous warts in cattle in Tamaulipas, Mexico.

Papillomas occur more frequently in cattle than other domestic animals. The causal agent of bovine papillomatosis is a virus that belongs to the family Papillomaviridae. In Tamaulipas, Mexico, the virus is considered a serious problem and has impeded the export of cattle to the United States, resulting in serious economic losses. Owing to the lack of information regarding the subtypes of papillomaviruses that infect cattle in Mexico, the aim of this study was to determine the subtypes in Tamaulipas. Fifty-two warts were analyzed with the use of polymerase chain reaction (PCR) involving primers that amplify the E7 gene of bovine papillomavirus (BPV). The PCR products were sequenced to differentiate the BPV-1 and BPV-2 subtypes. The sequencing quality was determined with the use of MEGA 6.0 software. Comparison of the Tamaulipas sequences with those of known BPV types by means of the MUSCLE algorithm showed that 53% of the former were BPV-1 and 47% were BPV-2. The distribution of the 2 subtypes in the cattle was homogeneous. This study demonstrated the presence of BPV-1 and BPV-2 in cattle from Tamaulipas and constitutes the first molecular characterization of papillomas in Mexico.

Les papillomes sont rencontrés plus fréquemment chez les bovins que chez n'importe quelle autre espèce domestiques. L'agent causal de la papillomatose bovine est un virus appartenant à la famille Papillomaviridae. Dans l'état mexicain de Tamaulipas le virus est considéré comme un problème sérieux et a empêché l'exportation de bovin vers les États-Unis d'Amérique, causant ainsi des pertes économiques importantes. Étant donné le manque d'information concernant les sous-types de papillomavirus qui infectent les bovins au Mexique, l'objectif de l'étude était de déterminer les sous-types présents dans l'état de Tamaulipas. Cinquante-deux verrues ont été analysées par réaction d'amplification en chaine par la polymérase (ACP) à l'aide d'amorces amplifiant le gène E7 du papillomavirus bovin (PVB). Les produits de l'ACP ont été séquencés afin de différencier les sous-types PVB-1 et PVB-2. La qualité du séquençage fut déterminée à l'aide du logiciel MEGA 6.0. La comparaison des séquences obtenues pour l'état de Tamaulipas avec celles des types connus de PVB par l'algorithme MUSCLE a permis de démontrer que 53 % étaient des PVB-1 et 47 % de PVB-2. La distribution des deux sous-types chez les bovins était homogène. La présente étude démontre la présence de PVB-1 et PVB-2 chez les bovins de Tamaulipas et constitue le premier rapport sur la caractérisation moléculaire des papillomes au Mexique.(Traduit par Docteur Serge Messier).

Genetic diversity of bovine papillomavirus types, including two putative new types, in teat warts from dairy cattle herds.

Teat papillomatosis affects dairy cows worldwide. Milking can become difficult due to teat warts, and maintaining affected cows in the herds may diminish economic profit in the dairy industry. Currently, 13 bovine papillomavirus (BPV) types have been fully characterized, and numerous putative BPV types have been identified through partial L1 gene PCR. In order to identify the viral types present in warts on the udders of dairy cows, 40 teat lesions from 24 cows from 13 cattle farms in three States of Brazil were evaluated by PV L1 gene PCR. The warts that were evaluated contained sequences from BPVs 6-10, the putative BPV types BAPV9 and BAPV4, and two unreported putative papillomavirus (PV) types, named BPV/BR-UEL6 and BPV/BR-UEL7. In addition, mixed infections and coinfections were identified, since more than one lesion was observed on the udders of 13 cows. Phylogenetic analysis showed that BPV/BR-UEL6 is closely related to BPVs belonging to the genus Xipapillomavirus, while BPV/BR-UEL7 clustered with the previously reported strains Cervus timorensis and Pudu puda PVs, which represent a putative new PV type, and it was only distantly related to xi-, epsilon-, delta- and dyoxi-PVs. These results provide information that will assist in the understanding of the association of BPVs 6, 7, 8, 9, and 10, as well as putative BPV types BAPV4 and BAPV9, with mammary papillomatosis. This is the first characterization of putative novel PV types BPV/BR-UEL6 and BPV/BR-UEL7 in teat warts of dairy cows, highlighting the high genetic diversity of BPVs associated with teat papillomatosis.

Human papillomavirus detected in viral warts of renal transplant recipients.

OBJECTIVES: Few studies have been conducted in South America regarding the detection and genotyping of human papillomavirus (HPV) in viral warts of renal transplant recipients (RTRs). The characterization of the population most susceptible to the development of warts and the knowledge of the main HPV types in this environment prompted this study, which focuses on the detection and typing of HPV in RTRs in Brazil. METHODS: Fifty-eight patients with viral warts from the Hospital São Paulo/Federal University of São Paulo were included in this study. HPV was detected by polymerase chain reaction (PCR) using combinations of the following primers: PGMY 09/11, RK 91, CP 65/70, and CP 66/69. Restriction fragment length polymorphism and automated sequencing techniques were used for HPV typing. RESULTS: HPV was detected by PCR in 89.7% of viral wart samples. The most frequently detected HPV types included 57, 27, 1a, 2a, and 20. Other types of HPV-epidermodysplasia verruciformis were also detected, including 14, 15, 19, 20, 21, 23, 36, and 38. Rare HPV types were also detected in our environment, including RTR X1, RTR X7, and 100. The time after transplant was correlated with an increased number of lesions and beta papillomavirus genus infection. CONCLUSIONS: The HPV types detected in the RTR population were similar to those described in immunocompetent populations. However, the diversity of the HPV types identified and the number of lesions were increased in the RTR population.

Genetic characterization of Amazonian bovine papillomavirus reveals the existence of four new putative types.

Papillomaviruses are small and complex viruses that belong to the Papillomaviridae family, which comprises 39 genera. The bovine papillomavirus (BPV) causes an infectious disease that is characterized by chronic and proliferative benign tumors that affect cattle worldwide. Different genotypes of BPVs can cause distinct skin and mucosal lesions and the immunity they raise has low cross-protection. This report aimed to genotype BPVs in cattle from Northern Brazil based on nucleotide partial sequences of the L1 ORF. Skin wart samples from 39 bovines clinically and histopathologically diagnosed as cutaneous papillomatosis from Acre and Rondônia States were analyzed. The results revealed four already reported BPV types (BPVs 1, 2, 11, and 13), nine putative new BPV subtypes and four putative new BPV types as well as two putative new BPV types that were already reported. To our knowledge, this is the first record of BPVs from the Brazilian Amazon region that identified new possible BPV types and subtypes circulating in this population. These findings point to the great genetic diversity of BPVs that are present in this region and highlight the importance of this knowledge before further studies about vaccination are attempted.

Bovine papillomavirus in Brazil: detection of coinfection of unusual types by a PCR-RFLP method.

Bovine papillomavirus (BPV) is recognized as a causal agent of benign and malignant tumors in cattle. Thirteen types of BPV are currently characterized and classified into three distinct genera, associated with different pathological outcomes. The described BPV types as well as other putative ones have been demonstrated by molecular biology methods, mainly by the employment of degenerated PCR primers. Specifically, divergences in the nucleotide sequence of the L1 gene are useful for the identification and classification of new papillomavirus types. On the present work, a method based on the PCR-RFLP technique and DNA sequencing was evaluated as a screening tool, allowing for the detection of two relatively rare types of BPV in lesions samples from a six-year-old Holstein dairy cow, chronically affected with cutaneous papillomatosis. These findings point to the dissemination of BPVs with unclear pathogenic potential, since two relatively rare, new described BPV types, which were first characterized in Japan, were also detected in Brazil.

Recognizing and treating anal cancer: training medical students and physicians in Puerto Rico.

OBJECTIVE: This training activity aimed at increasing the knowledge of anal cancer screening, diagnostic and treatment options in medical students and physicians, to determine the interest of these individuals in receiving training in the diagnosis and treatment of anal cancer, and to explore any previous training and/or experience with both anal cancer and clinical trials that these individuals might have. METHODS: An educational activity (1.5 contact hours) was attended by a group of medical students, residents and several faculty members, all from the Medical Sciences Campus of the University of Puerto Rico (n = 50). A demographic survey and a 6-item pre- and post-test on anal cancer were given to assess knowledge change. RESULTS: Thirty-four participants (68%) answered the survey. Mean age was 29.6 +/- 6.6 years; 78.8% had not received training in anal cancer screening, 93.9% reported being interested in receiving anal cancer training, and 75.8% expressed an interest in leading or conducting a clinical trial. A significant increase in the test scores was observed after the educational activity (pre-test: 3.4 +/- 1.2; post-test: 4.7 +/- 0.71). Three of the items showed an increase in knowledge by the time the post-test was taken. The first of these items assessed the participants' knowledge regarding the existence of any guidelines for the screening/treatment of patients with human papillomavirus (HPV)-related anal disease. The second of these items attempted to determine whether the participants recognized that anal intraepithelial neoplasia (AIN) 2 is considered to be a high-grade neoplasia. The last of the 3 items was aimed at ascertaining whether or not the participants were aware that warty growths in the anus are not necessarily a manifestation of high-grade AIN. CONCLUSION: This educational activity increased the participants' knowledge of anal cancer and revealed, as well, that most of the participants were interested in future training and in collaborating in a clinical trial. Training physicians from Puerto Rico on anal cancer clinical trials is essential to encourage recruitment of Hispanic patients in these studies now that the guidelines in anal cancer screening and treatment are on their way to be defined.

Co-infection of Bovine Papillomavirus and feline-associated Papillomavirus in bovine cutaneous warts.

The diversity of papillomavirus (PV) found in bovine cutaneous warts from Brazilian cattle was evaluated using the PCR technique with the utilization of consensus primers MY09/11 and by PCR using Bovine Papillomavirus (BPV) type-specific primers followed by sequencing. Eleven cutaneous warts from 6 cattle herds were selected. Six warts were positive for the presence of PV. The presence of BPV types 1, 2, 3, 6 and feline sarcoid-associated PV (FeSarPV) in cutaneous wart lesions, as well as the presence of co-infections, was found. To the best of our knowledge, this is the first time that FeSarPV is described co-infecting a cutaneous wart in Brazil. The present study confirms the previous finding of FeSarPV infecting cattle. These results show the necessity of more studies to investigate the diversity of PV in cattle, its diversity and the possibility of co-infection in cattle and other animals.

Human papillomavirus infection: etiopathogenesis, molecular biology and clinical manifestations.

Human papillomavirus (HPV) is a DNA virus that presents tropism for epithelial cells, causing infections of the skin and mucous membranes. Replication of HPV occurs in the nuclei of squamous cells and its life cycle is directly related to the differentiation program of the host cell. To date, nearly 100 different types of HPV have been characterized and there is a large number of other types that have not been sequenced yet. Besides being responsible for benign lesions of the skin and mucous membranes, HPV is also involved in the development of various mucocutaneous tumors: Bowen's disease, non-melanoma skin cancers and genital carcinomas. This review discusses the characteristics of HPV, malignant and benign mucous and skin manifestations caused by HPV, besides the main methods of detection and typing of the virus.

Clinical and histopathological characterization and typing of the human papillomavirus in common warts of kidney transplant recipients.

The prevalence of skin lesions caused by the human papillomavirus (HPV) is high in kidney transplant patients. Twenty recipients of kidney transplants with a diagnosis of common warts were evaluated. HPV detection was performed by polymerase chain reaction (PCR) using the MY09/MY11 and RK91 primers. HPV typing was performed by restriction fragment length polymorphism analysis and direct sequencing. The presence of HPV was identified in 10 patients (50%) and the types identified were HPV-2, 27, 29, 34 and 57.

HLA-DR alleles associated with skin warts induced by human papillomavirus infection.

BACKGROUND: The skin wart is a benign proliferation of the skin and mucous, secondary to human papillomavirus (HPV) infection. OBJECTIVES: The objective of this study is to determine gene frequencies of HLA-DR alleles in Mexican patients with skin warts and compare them with those present in ethnically matched healthy subjects. METHODS: Fifty-two patients with clinically and histologically confirmed skin warts from the Dermatology Outpatient Clinic, with results of high-resolution DNA typing for HLA-DR polymorphism. RESULTS: HLA-DR3 and DR9 were increased (P = 0.0029, OR: 2.5, 95% CI: 1.3­4.7 and P = 0.0062, OR: 5.4, 95% CI: 1.4­19.5, respectively), and HLA-DR6 allele was found decreased (P = 0.0002). LIMITATIONS: The major histocompatibility complex contribution in the infection and elimination of the virus is not clear and perhaps also contributes to a series of events not well established yet. CONCLUSIONS: This study follows the preponderant role of class II genes in the susceptibility or resistance to the development of skin warts caused by HPV infection.

Caracterização clínica e histopatológica e tipagem do papilomavírus humano das verrugas vulgares nos receptores de transplante renal / Clinical and histopathological characterization and typing of the human papillomavirus in common warts of kidney transplant recipients

Os pacientes receptores de transplante renal apresentam elevada prevalência de lesões cutâneas por HPV. Foram estudados 20 receptores de transplante renal com diagnóstico de verruga vulgar. A detecção do HPV foi realizada pela polimerização em cadeia (PCR) com os primers MY09/MY11 e RK91. A tipagem do HPV foi feita por meio da restrição enzimática e do sequenciamento automatizado. Identificamos a presença do HPV em 10 pacientes (50 por cento) e os tipos identificados foram: HPV-2, 27, 29, 34 e 57.
