Abstract
Mycoplasma genitalium is an emerging sexually transmitted infection, with increasing rates of macrolide resistance and some ways of treatments being recommended by many countries. This study aimed to investigate the prevalence of M. genitalium infection, M. genitalium co-infection with other sexually transmitted organisms, and the frequency of macrolide antibiotic resistance genotypes identified in urethral specimens collected from male and urethral, vaginal and cervical specimens from female who visited the STIs clinic of HCMC Hospital of Dermato-Venereology, Vietnam. The results obtained positive samples for C. trachomatis was 8.46%, N. gonorrhoeae was 6.28%, and M. genitalium was 5.95%. Fifty-five out of 90 M. genitalium samples were found to have mutations in the 23S rRNA gene associated with macrolide resistance (61.11%). M. genitalium/C. trachomatis co-infection was 6.19%, and M. genitalium/N. gonorrhoeae was 1.22%. The percentage of M. genitalium carrying the macrolide resistance mutant gene co-infected with C. trachomatis accounted for 37.50%. The high prevalence of the M. genitalium mutations associated with macrolide resistance showed the importance of M. genitalium testing.

Human Papillomavirus (HPV) Infections Among Participants Undergoing Chlamydia trachomatis Testing in Reunion Island (RUN-SurV-HPV Study): Protocol for a Prevalence Study. JMIR Res Protoc 2023; 12:e47379. [PMID: 37906221 PMCID: PMC10646676 DOI: 10.2196/47379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 09/01/2023] [Accepted: 09/08/2023] [Indexed: 11/02/2023] Open
Abstract
BACKGROUND Infection by human papillomavirus (HPV) induces various cancers, mainly cervical cancer but also anal and pharyngeal cancers. Reunion Island is a French department in the Indian Ocean. Due to the history of its settlement, the island's population has a wide variety of origins, and the population's sociodemographic characteristics differ from those of the French mainland. These characteristics make the island's population an original French population in its own right, particularly in terms of health. Cervical cancer incidence and mortality in Reunion Island are 10.4 per 100,000 and 4.4 per 100,000, respectively, both of which are much higher than those in mainland France. There is also a disparity in the prevalence of different HPV types, with types 33 and 52 being overrepresented and type 18 being underrepresented. However, vaccination and screening coverage in Reunion Island is low. It is important to understand the burden of infection and its risk factors in members of the young Reunionese population at risk of HPV infection to promote and evaluate the implementation of future vaccination and screening programs on a larger scale. OBJECTIVE The RUN-SurV-HPV study will have the following four objectives: (1) to describe the prevalence of HPV genotypes in a population at risk of sexually transmitted infections in Reunion Island; (2) to describe the prevalence of HPV genotypes by anatomical site, gender, and sexuality; (3) to describe the correlates and risk factors for HPV detection; and (4) to examine HPV genotypes between different anatomical sites. METHODS Cross-sectional analyses of 1200 routine vaginal, anal, pharyngeal, and urinary samples collected between October 2020 to December 2022 from female and male patients aged 16 to 30 years undergoing Chlamydia trachomatis testing at a sexually transmitted infection (STI) testing center at Reunion Island will be performed. The population included 333 women who all had vaginal and pharyngeal swabs, with 80 of them also having had an anal swab. There are 167 men who have sex with men who have had anal and pharyngeal swabs, and 120 men who have sex with women who have had a urine swab only. Results will be correlated with sociodemographic and clinical data collected routinely during the consultations. HPV detection and genotyping will be performed using the Anyplex II HPV28 detection assay (Seegene). RESULTS The first polymerase chain reactions should begin in November 2023. The first results should be submitted for publication in 2024. CONCLUSIONS The study will determine HPV prevalence by age, sex, male sexual preference, human immunodeficiency virus status, and STI co-infection. Collecting data from young patients not usually routinely screened for HPV infection will be a simple and reproducible way of better understanding local specificities, encouraging vaccination campaigns in the short-term, and evaluating their effectiveness in the future.

Prevalence of Mycoplasma hominis, Ureaplasma urealyticum, and Ureaplasma parvum detection in urine and respiratory tract samples in Hiroshima, Japan. Heliyon 2023; 9:e14543. [PMID: 36967949 PMCID: PMC10036642 DOI: 10.1016/j.heliyon.2023.e14543] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 03/06/2023] [Accepted: 03/09/2023] [Indexed: 03/16/2023] Open
Abstract
Background Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum are commensal bacteria that are associated with colonization and infection of the urogenital tract. However, colonization of the respiratory tract by these microorganisms in adults has not been fully investigated. Methods Urine and respiratory tract samples (sputum, tracheal aspirates, and bronchoalveolar lavage) of patients aged 20-80 years were analyzed to detect the presence of M. hominis, U. parvum, and U. urealyticum using a conventional PCR method. The samples were submitted to the microbiological clinical laboratory of Hiroshima University Hospital from December 1, 2021 to May 31, 2022. Results In total, 334 urine and 238 respiratory tract samples were analyzed. The overall detection rates of M. hominis, U. parvum, and U. urealyticum were 2.9%, 1.7%, and 2.3% in male urine; 7.0%, 13.8%, and 1.9% in female urine; 2.2%, 0%, and 2.2% in male respiratory tract; and 0%, 2.0%, and 0% in female respiratory tract, respectively. In urine samples, the detection rates of M. hominis, U. parvum, and U. urealyticum were significantly higher (p < 0.001) for women (29/159; 18.2%) than for men (10/175; 5.7%); however, in respiratory tract samples, the detection rates were not significantly different (p = 0.70) between women (2/101; 2.0%) and men (5/137; 3.7%). Further, both the urine and respiratory samples of 83 patients were analyzed. Three male samples were positive for M. hominis or U. urealyticum, and M. hominis and U. urealyticum were matched in both the urine and respiratory tract samples: M. hominis (n = 1), U. urealyticum (n = 1), M. hominis + U. urealyticum (n = 1). Conclusion M. hominis, U. parvum, and U. urealyticum were detected in the respiratory tract of not only the young patients, but also of patients aged 50-60 years. Further studies are required to understand the relationship of these microorganisms in urogenital and respiratory tract samples with extra-genital infections.

Abstract
The majority of sexually active individuals becomes infected with human papillomavirus (HPV) at least once in their lifetime. Pathways for HPV transmission vary across different mucosal sites per individual. They include autoinoculation within one host, direct transmission between individuals (including perinatal transmission and transmission during sexual activity), and indirect transmission through contact with hands. The authors aim to clarify the prevalence and route of transmission per anatomic site, inter- and intra-individually, using a narrative review of the literature. In conclusion, transmission of HPV to the oral cavity and oropharynx is hypothesised to occur mainly through sexual contact. Transmission of particles through saliva has not been proven and daily living activities are not a documented source of HPV infection. Oropharyngeal HPV related cancer survivors and their partners do not show increased risk of infection during sexual intercourse. Transmission of HPV to the oral cavity (autoinoculation with fingers or transmission through saliva in deep kissing) is probably of limited importance.

Abstract
PURPOSE OF REVIEW Hyperammonemia syndrome is an increasingly recognized and often fatal condition that occurs in immunosuppressed individuals, most commonly lung transplant recipients. Growing evidence suggests hyperammonemia syndrome is associated with systemic infections caused by urease-producing organisms, namely Ureaplasma spp., an organism unable to grow with routine culturing techniques. This review will summarize the epidemiology and clinical manifestations of hyperammonemia syndrome, as well as diagnostic and management strategies once hyperammonemia syndrome is suspected. RECENT FINDINGS Hyperammonemia syndrome is being described in increasing frequency in the solid organ transplant population. Morbidity and mortality, even with treatment, is high once hyperammonemia syndrome occurs. Surveillance studies indicate the prevalence of lung donor colonization with Ureaplasma spp. is high, suggesting screening and treatment may be of benefit. Antibiotic resistance is common, and rapid diagnostics can facilitate appropriate antimicrobial therapy in the peri-transplant period. SUMMARY Hyperammonemia syndrome is most commonly seen in lung transplant recipients and has a high mortality rate once it occurs. Screening for Ureaplasma spp. should be considered in all lung transplant donors.

Abstract
Mycoplasma genitalium (MG) is a common cause of nongonococcal cervicitis and urethritis. We investigated the demographic and clinical characteristics of patients tested in Denmark with the Conformité Européenne (CE)/in vitro diagnostics (IVD) Aptima Mycoplasma genitalium assay (CE/IVD AMG; Hologic) and examined the clinical significance of the higher sensitivity of the TMA-based MG assays. From March to June 2016, urogenital and extragenital specimens from consecutive attendees at a sexually transmitted infection clinic in Copenhagen, Denmark were tested with the CE/IVD AMG assay (TMA-based), the research-use-only MG Alt TMA-1 assay (Hologic), a laboratory-developed TaqMan mgpB quantitative real-time PCR (qPCR), and the Aptima Combo 2 (CT/NG; Hologic). Demographic characteristics and clinical symptoms were collected from the patient records. There were 1,245 patients included in the study. The MG prevalence among female subjects was 9.4%, and the MG prevalence among male subjects was 8.7%. Compared to the TMA-based assays, the sensitivity of the PCR-based MG assay was 64.52%, and 55 specimens from 48 individuals were missed in the mgpB qPCR. Of these, 26 individuals (54.2%) were symptomatic, whereas, among 64 individuals with concordant results, 30 individuals (46.9%) were symptomatic; no statistically significant difference was found between the groups (P = 0.567). The improved sensitivity of the TMA-based assays resulted in diagnoses of more patients with clinically relevant symptoms for which antibiotic treatment is indicated. However, approximately half of the MG-infected patients reported no symptoms, and future research is needed to investigate the pros and cons of diagnosing and treating MG in asymptomatic subjects.

Abstract
ABSTRACT The Centers for Disease Control and Prevention (CDC) recommend screening men who have sex with men who are living with HIV for sexually transmitted infections at appropriate extragenital contact sites for bacterial sexually transmitted infections. In an effort to increase provider adherence to CDC recommended guidelines at a Ryan White Clinic, microlearning educational sessions were used. A quality improvement project was designed to determine the rate of provider adherence to CDC guidelines pre/post microlearning sessions. Student t-test was used to compare the number of patients who received urine and extragenital screening to those who received urine-only screening, to before and after the microlearning sessions. The rate of extragenital screening significantly increased after the microlearning sessions (4/460 vs. 70/507, p < .0001). The rate of urine screening remained unchanged (p = 1). Although extragenital screening significantly increased, it remained low. A decision tree in the electronic medical record to prompt providers to screen was developed.

Abstract
BACKGROUND Mycoplasma genitalium is an important emerging sexually transmitted pathogen commonly causing urethritis in men, cervicitis, and pelvic inflammatory disease in women with potential of infertility. Accumulating evidence identifies the prevalence of M. genitalium similar to long recognized pathogens, Chlamydia trachomatis and Neisseria gonorrhoeae. The purpose of this study was to establish the prevalence and epidemiology of M. genitalium in a mid-Pacific military population. METHODS A prospective analysis was conducted from routine specimens collected as standard of care for sexually transmitted infection (STI) testing at Tripler Army Medical Center on Oahu, HI. The prevalence of M. genitalium was determined using the Aptima M. genitalium assay, a transcription-mediated amplification test. A multivariate analysis was performed to assess the associations for this infection with other STIs and demographic factors. RESULTS A total of 1876 specimens were tested in a 6-month period including 6 sample types from 1158 females and 718 males. Subject ages ranged from 18 to 76 years, with a median of 24 years (interquartile range, 21-29 years). The prevalence of M. genitalium was 8.8% overall (n = 165), 7.1% in females and 11.6% in males. Coinfection with M. genitalium occurred with another sexually-transmitted pathogen in 43 patients (18.3%), with C. trachomatis as the most common organism (n = 38). CONCLUSIONS These data contribute to the evidence base for M. genitalium and STI screening in an active-duty military.

Abstract
OBJECTIVE To estimate the prevalence of oral high-risk human papillomavirus (hr-HPV) infection and the proportion of hr-HPV-related oropharyngeal squamous cell carcinoma (OPSCC) among Indigenous and non-Indigenous populations. DATA SOURCE Electronic database searches of PubMed, PubMed Central, Embase, MEDLINE, Scope, and Google Scholar were conducted for articles published from January 2000 until November 2019. REVIEW METHODS Studies were included with a minimum of 100 cases assessing hr-HPV infection in either population samples or oropharyngeal cancer tumor series. The objective was to conduct meta-analyses to calculate the pooled prevalence of oral hr-HPV infection by adjusting for age group or sex in primary studies, the incidence of OPSCC, and the proportion of hr-HPV-related OPSCC in Indigenous people and non-Indigenous/general populations. RESULTS We identified 47 eligible studies from 157 articles for meta-analyses. The pooled prevalence of oral hr-HPV infection was 7.494% (95% CI, 5.699%-9.289%) in a general population, with a higher prevalence among men (10.651%) than women (5.176%). The pooled incidence rate was 13.395 (95% CI, 9.315-17.475) and 7.206 (95% CI, 4.961-9.450) per 100,000 person-years in Indigenous and non-Indigenous populations, respectively. The overall pooled proportion of hr-HPV-related OPSCC was 50.812% (95 CI, 41.656%-59.969%). The highest proportion was in North America (60.221%), while the lowest proportion was in the Asia-Pacific (34.246%). CONCLUSION Our findings suggest that in the general population, the prevalence of oral hr-HPV infection is lower among females and those in younger age groups. The incidence of OPSCC was higher among Indigenous than non-Indigenous populations, with the proportion being highest in North America.

Abstract
A significant subset of carcinomas developed in the head and neck (H&NCs) are associated with specific human papillomaviruses (HPV) genotypes. In particular, 40–60% of oropharyngeal carcinoma cases are linked to HPV. Epidemiological studies have demonstrated that HPV oral infections are predominantly sexually transmitted and are more frequent among men (10–18%) than women (3.6–8.8%). Although there is a large diversity of HPV genotypes associated with H&NCs, HPV16 lineage represents 83% of the reported cases. The prognostic value of HPV as a biological parameter is well recognized. However, the use of HPV DNA as a diagnostic and/or predictive marker is not fully developed. Recent data reporting the physical state of the HPV genome in tumors have shown that HPV DNA integration into the tumor cell genome could lead to the alteration of cellular genes implicated in oncogenesis. Most importantly, HPV DNA corresponds to a tumor marker that can be detected in the blood of patients. Profile of the HPV DNA molecular patterns in tumor cells using New Genome Sequencing-based technologies, allows the identification of highly specific tumor markers valuable for the development of innovative diagnostic and therapeutic approaches. This review will summarize recent epidemiological data concerning HPV-associated H&NCs, the genomic characterization of these tumors, including the presence of HPV DNA in tumor cells, and will propose perspectives for developing improved care of patients with HPV-associated H&NCs, based on the use of viral sequences as personalized tumor markers and, over the longer term, as a therapeutic target.

Abstract
Background: Certain high-risk (hr) types of human papillomavirus (HPV) can cause cervical cancer in women and penile cancer in men. Hr-HPV can also cause cancers of the oropharynx and anus in both sexes. In the anal and cervical region, a contribution of co-infections with Ureaplasma spp. on the persistence of the hr-HPV infection by a profound inflammatory state is suggested. Here, we investigated if non-HPV sexually transmitted infections are associated with oropharyngeal carcinoma (OPC). Materials and Methods: In this case-control study, a brush test directly from the tumor surface of OPC patients (study group) and from the oropharynx of healthy volunteers (control group), both groups matching in age and sex, was performed. HPV subtypes were detected using a commercially available test kit. For non-HPV sexually transmitted infections (Ureaplasma spp., Chlamydia trachomatis, Mycoplasma hominis, and Mycoplasma genitalium), a multiplex nucleic acid amplification approach was performed. Results: In the study group, 96 patients (23 female/73 male), with histologically confirmed OPC and in the control group 112 patients (19 female/93 male), were included. Oropharyngeal hr-HPV-positivity was detected in 68% (65/96 patients) of the study group and 1.8% (2/112 patients) of the control group (p < 0.001). In three patients in the study group, Ureaplasma spp. was detected, whereas no patient was Ureaplasma spp. positive in the control group (p = 0.097). Chlamydia trachomatis, Mycoplasma hominis, and Mycoplasma genitalium were negative in both groups. Conclusion: Based on the current study, the prevalence of oropharyngeal Ureaplasma spp. among patients with OPC is low and does not support a role in oropharyngeal cancer. However, the detection of the pathogen only among OPC patients but not in the healthy individuals might indicate a potential role and needs further elucidation.

STI in times of PrEP: high prevalence of chlamydia, gonorrhea, and mycoplasma at different anatomic sites in men who have sex with men in Germany. BMC Infect Dis 2020; 20:110. [PMID: 32033533 PMCID: PMC7007644 DOI: 10.1186/s12879-020-4831-4] [Citation(s) in RCA: 85] [Impact Index Per Article: 21.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 01/28/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Men who have sex with men (MSM) are disproportionally affected by sexually transmitted infections (STI). STI are often extragenital and asymptomatic. Both can delay diagnosis and treatment. Approval of HIV pre-exposure prophylaxis (PrEP) might have influenced sexual behaviour and STI-prevalence of HIV- MSM. We estimated STI-prevalence and risk factors amongst HIV- and HIV+ MSM in Germany to plan effective interventions. METHODS We conducted a nationwide, cross-sectional study between February and July 2018. Thirteen MSM-friendly STI-practices screened MSM for Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Neisseria gonorrhea (NG), and Trichomonas vaginalis (TV) using self-collected rectal and pharyngeal swabs, and urine samples. APTIMA™ STI-assays (Hologic™ Inc., San Diego, USA) were used for diagnostics, and samples were not pooled. We collected information on socio-demographics, HIV-status, clinical symptoms, sexual behaviour within the last 6 months, and PrEP use. We combined HIV status and PrEP use for defining risk groups, and used directed acyclic graphs and multivariable logistic regression to identify risk factors for STI. RESULTS Two thousand three hundred three MSM were included: 50.5% HIV+, median age 39 [18-79] years. Median number of male sex partners within the last 6 months was five. Sex without condom was reported by 73.6%, use of party drugs by 44.6%. 80.3% had a STI history, 32.2% of STI+ MSM reported STI-related symptoms. 27.6% of HIV- MSM used PrEP. Overall STI-prevalence was 30.1, 25.0% in HIV-/PrEP- MSM (CT:7.2%; MG:14.2%; NG:7.4%; TV:0%), 40.3% in HIV-/PrEP+ MSM (CT:13.8%; MG:19.4%; NG:14.8%; TV:0.4%), and 30.8% in HIV+ MSM (CT:10.1%; MG:18.4%; NG:8.6%; TV:0.1%). Being HIV+ (OR 1.7, 95%-CI 1.3-2.2), using PrEP (OR 2.0, 95%-CI 1.5-2.7), having > 5 sex partners (OR:1.65; 95%-CI:1.32-2.01.9), having condomless sex (OR:2.11.9; 95%-CI:1.65-2.86), and using party drugs (OR:1.65; 95%-CI:1.32-2.0) were independent risk factors for being tested positive for at least one STI. CONCLUSIONS We found a high STI-prevalence in MSM in Germany, especially in PrEP users, frequently being asymptomatic. As a relevant proportion of PrEP users will not use a condom, counselling and comprehensive STI screening is essential and should be low threshold and preferably free of cost. Counselling of PrEP users should also address use of party drugs.

Abstract
The present study investigated the prevalence of Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, M. hominis, and Ureaplasma spp. (biovars 1 and 2) in Japanese HIV-positive men who have sex with men (MSM). One-hundred-and-six Japanese HIV-infected MSM patients were enrolled. Anal and urine samples were collected and DNA testing for each microorganism was performed. Questionnaires regarding lifestyle habits and sexual behavior were administered. The prevalence of N. gonorrhoeae, C. trachomatis, M. genitalium, M. hominis, and Ureaplasma spp. in the anus was 5.6%, 8.9%, 4.4%, 5.6%, and 8.9%, respectively. A history of genital warts was an independent risk factor for detection of Mycoplasma spp. and Ureaplasma spp. The prevalence of these microorganisms in the anus of asymptomatic Japanese HIV-positive MSM was relatively high in agreement with previous reports from other countries.

Abstract
During 2016-2017, we tested asymptomatic men who have sex with men (MSM) in Melbourne, Australia, for Mycoplasma genitalium and macrolide resistance mutations in urine and anorectal swab specimens by using PCR. We compared M. genitalium detection rates for those asymptomatic men to those for MSM with proctitis and nongonococcal urethritis (NGU) over the same period. Of 1,001 asymptomatic MSM, 95 had M. genitalium; 84.2% were macrolide resistant, and 17% were co-infected with Neisseria gonorrhoeae or Chlamydia trachomatis. Rectal positivity for M. genitalium was 7.0% and urine positivity was 2.7%. M. genitalium was not more commonly detected in the rectums of MSM (n = 355, 5.6%) with symptoms of proctitis over the same period but was more commonly detected in MSM (n = 1,019, 8.1%) with NGU. M. genitalium is common and predominantly macrolide-resistant in asymptomatic MSM. M. genitalium is not associated with proctitis in this population.

Abstract
A prospective multicenter clinical study involving subjects from 21 sites across the United States was conducted to validate the performance of a new in vitro diagnostic nucleic acid amplification test (NAAT) for the detection of Mycoplasma genitalium. A prospective multicenter clinical study involving subjects from 21 sites across the United States was conducted to validate the performance of a new in vitro diagnostic nucleic acid amplification test (NAAT) for the detection of Mycoplasma genitalium. Seven urogenital specimen types (n = 11,556) obtained from 1,778 females, aged 15 to 74 years, and 1,583 males, aged 16 to 82 years, were tested with the Aptima Mycoplasma genitalium assay, an investigational transcription-mediated amplification (TMA) NAAT for the detection of M. genitalium 16S rRNA. Infected status for enrolled subjects was established using results obtained from testing either self-collected vaginal swab or clinician-collected male urethral swab specimens with a composite reference method consisting of three transcription-mediated amplification NAATs targeting unique regions of M. genitalium 16S or 23S rRNA. M. genitalium prevalence was 10.2% in females and 10.6% in males; prevalence was high in both symptomatic and asymptomatic subjects for both sexes. Compared to the subject infected status standard, the investigational test had sensitivity and specificity estimates, respectively, of 98.9% and 98.5% for subject-collected vaginal swabs, 92.0% and 98.0% for clinician-collected vaginal swabs, 81.5% and 98.3% for endocervical swabs, 77.8% and 99.0% for female urine, and 98.2% and 99.6% for male urethral swabs, 88.4% and 97.8% for self-collected penile meatal swabs, and 90.9% and 99.4% for male urine specimens. For all seven specimen types, within-specimen positive and negative agreements between the investigational test and the composite reference standard ranged from 94.2% to 98.3% and from 98.5 to 99.9%, respectively. These results provide clinical efficacy evidence for the first FDA-cleared NAAT for M. genitalium detection in the United States.

Abstract
Background Human papillomavirus (HPV) causes cancers in men, including penile, anal, and oropharyngeal cancers. This cross-sectional study aimed to investigate the prevalence, the genotypes, and the risk factors of HPV infections in the oral cavity, compared to those in the genitals, among males diagnosed with sexually transmitted infections (STIs) in Vietnam. Methods Oral, urinary, penile, and urethral samples were collected from 198 male Vietnamese patients with STIs (median age 31.0 years, range 17–68). HPV DNA was isolated and amplified with PCR, with modified and/or original GP5+/GP6+ primers. Samples were genotyped with a gene array assay and/or population sequencing. Results HPV DNA was detected in 69 (34.8%) of 198 patients. Of these, 16 patients (8.1%) had infections in the oral cavity and 58 (29.3%) had infections in the genitals (4.5% in the urine, 25.8% in the penis, and 8.1% in the urethra). The concordance of HPV infections between the oral cavity and the genitals was poor (kappa = 0.01). Of the 16 patients with oral HPV DNA, 11 (68.8%) had no HPV DNA in the genitals. In the remaining five patients, HPV DNA was found at both sites, but only one showed similar strains at both sites. In the other four patients, the HPV genotypes were completely discordant between these sites. HPV18 was the most common high-risk HPV genotype in both oral (9/16, 56.3%) and genital (10/58, 17.2%) sites. Multivariable analyses showed that older age (OR 1.05), higher education (OR 2.17), and no knowledge of STIs (OR 4.21) were independent risk factors for genital HPV infections; in contrast, only older age (OR 1.05) was an independent risk factor for oral HPV infections. Conclusions The low concordance of HPV genotypes between oral and genital infection sites suggested that the acquisition, persistence, and/or clearance of HPV infections were different between these sites. Although HPV DNA was detected significantly less frequently in oral samples than in genital samples, oral samples should also be used for HPV screening in men.

Abstract
Objective: Provide evidence of HPV, C. trachomatis, and HSV infection in the oral cavity from patients with different types of stomatological lesions. Materials and Methods: Oral swabs samples were collected from a total of 318 patients. The infectious agents were analyzed using the PCR technique. HPV genotyping and HSV type were studied using the RFLP method. Results: We studied 137 benign lesions (B), 96 potentially malignant disorders (PMD) and 85 oral squamous cell carcinomas (OSCC). The prevalence of HPV was 34%. The most frequently genotypes detected were 6 low risk and 16 high risk. The prevalence of C. trachomatis was 16% and HSV 3%. Co-infections were detected mostly in benign lesions as following: HPV-C. trachomatis in 4%, C. trachomatis- HSV in 1.8% and HPV-HSV in 0.3%. Conclusion: This report is the first contribution to the identification and genotype characterization of HPV in a scenario little studied in our area, and it also contributes to improving our understanding on sexually transmitted infectious agents and their associations with the oral cavity. Besides, we detect the presence of C. trachomatis and HSV and co-infection with HPV in the oral cavity, which they should be taken into account for diagnostic and treatment purposes.

[PMID: 31190451 DOI: 10.1111/andr.12646] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 03/13/2019] [Accepted: 04/10/2019] [Indexed: 01/25/2023]
Abstract
BACKGROUND Mycoplasma genitalium infection is significantly associated with an increased risk of male infertility. To date, few large M. genitalium studies have been conducted in China. OBJECTIVE This study aimed to estimate the M. genitalium incidence and treatment failure and to provide information regarding the resistance of M. genitalium to macrolide and tetracycline antibiotics among men of infertile couples in China. MATERIALS AND METHODS This study was performed as a retrospective survey of seminal and meatus urinarius secreta specimens of 30,094 men of infertile couples collected and used for microbiological tests for the evaluation of genital tract infections (Mycoplasma genitalium, Chlamydia trachomatis, and Neisseria gonorrhoeae) between October 2016 and December 2017. Mycoplasma genitalium RNA was detected using novel simultaneous amplification testing. Macrolide and tetracycline resistance screening was introduced using polymerase chain reaction (PCR) and Sanger sequencing. RESULTS The incidence of M. genitalium was 2.49% (749 of 30,094; 95% confidence interval (CI), 2.31-2.66%). After antibiotic treatment, the mean values of semen parameters increased from those measured before treatment. The overall incidence of treatment failure was 17.56% (82/467; 95% CI, 14.10%-21.02%) (112-26-4 = 82), irrespective of the drug used. Resistance to macrolide and tetracycline antibiotics was detected in 58 samples (58/60, 96.67%; 95% CI, 91.99-101.34%) and 27 samples (27/60, 45.00%; 95% CI, 32.04-57.96%), respectively. CONCLUSIONS Although the M. genitalium incidence was relatively low, the detection of macrolide antibiotic resistance in >96.67% of the treatment failure samples most likely explained the high azithromycin treatment failure rate (73/195, 37.44%) in our study. These findings indicate the need to provide resistance testing and to reappraise the recommended antimicrobial options in China.

Abstract
In 2016, the Transplantation Society of Australia and New Zealand, with the support of the Australian Government Organ and Tissue authority, commissioned a literature review on the topic of infectious disease transmission from deceased donors to recipients of solid organ transplants. The purpose of this review was to synthesize evidence on transmission risks, diagnostic test characteristics, and recipient management to inform best-practice clinical guidelines. The final review, presented as a special supplement in Transplantation Direct, collates case reports of transmission events and other peer-reviewed literature, and summarizes current (as of June 2017) international guidelines on donor screening and recipient management. Of particular interest at the time of writing was how to maximize utilization of donors at increased risk for transmission of human immunodeficiency virus, hepatitis C virus, and hepatitis B virus, given the recent developments, including the availability of direct-acting antivirals for hepatitis C virus and improvements in donor screening technologies. The review also covers emerging risks associated with recent epidemics (eg, Zika virus) and the risk of transmission of nonendemic pathogens related to donor travel history or country of origin. Lastly, the implications for recipient consent of expanded utilization of donors at increased risk of blood-borne viral disease transmission are considered.

Abstract
BACKGROUND Chlamydia trachomatis is the most prevalent bacterial sexually transmitted infection (STI) in the world. Approximately 80% of infected women are asymptomatic, although this infection can lead to serious complications in the female reproductive tract. Few data on Chlamydia infection are available in rural Amazonian communities. OBJECTIVES To evaluate the prevalence of sexual C. trachomatis infection in women from Marajó Archipelago communities in the Amazon region of Brazil and to identify associated factors and genotypes. METHODS We utilized amplification of the ompA gene by nested PCR. Positive samples were genotyped by sequencing. Study participants completed a questionnaire on social, epidemiological, and reproductive health variables. A Poisson regression was used to evaluate the degree of association of these variables with the infection. RESULTS The sexual infection by C. trachomatis was observed in 4% (16/393) of the subjects, and was more often found in women aged ≤25 (14.3%; 95% CI = 2.83-35.47; p <0.001), and in women with a household income of less than one Brazilian monthly minimum wage (5.2%; 95% CI = 1.33-11.37; p = 0.014). The ompA gene was sequenced in 13 samples, revealing F genotypes (38.4%, n = 5), D (23%, n = 3), E (15.3%, n = 2), Ia (7.6%, N = 1), J (7.6%, n = 1) and B (7.6%, n = 1). CONCLUSIONS We recorded a high prevalence of sexual infection by C. trachomatis in young and poor women from the interior of the Brazilian Amazon. This high prevalence and the frequencies of the main genotypes were similar to those found in major Brazilian urban centers. Our results reinforce the importance of the screening of this neglected infection, and the prevention of later sequelae in young women from rural and urban areas of Brazil.

Abstract
OBJECTIVE We investigated the association between bacterial microbiota in breast milk and the infant mouth. The influence of human papilloma virus (HPV) infection on infant oral microbiota was also assessed. MATERIAL AND METHODS Altogether 35 breast milk and 35 infant oral samples with known HPV status were selected from the Finnish Family HPV Study cohort. In total, there were 31 mother-infant pairs. The microbiota composition was characterized by 16S rRNA gene sequencing (V3-V4 region). RESULTS HPV DNA was present in 8.6% (3/35) of the breast milk and 40% (14/35) of the infant oral samples. Eight shared genera between breast milk and infant oral were found; these included Streptococcus, Staphylococcus, Unclassified Gemellaceae, Rothia, Veillonella, Haemophilus, Propionibacterium and Corynebacterium. HPV status was not associated with either microbiota richness or diversity in the infant mouth. However, the infant oral microbiota clustered in different groups according to HPV status. We detected higher abundance of Veillonella dispar (p = 0.048) at species level in HPV negative infant oral samples. We did not detect differences in the breast milk microbiota composition related to HPV infection due to only three HPV positive milk samples. CONCLUSIONS HPV infection is associated with distinct oral bacterial microbiota composition in infants. The direction of causality underlying the phenomenon remains unclear.

Abstract
Human papillomavirus (HPV) is a potentially oncogenic sexually transmitted infection. As the incidence of oropharyngeal cancer (OPC) caused by oral HPV infections is rising, further investigation into the natural history of such infections is needed. This systematic review and meta-analysis aimed to synthesize data on the prevalence, incidence, clearance, and persistence of oral HPV infections in healthy individuals. A systematic review of literature published between January 1995 and August 2017 was conducted using Ovid MEDLINE, PubMed, Embase, and the Cochrane Library. Meta-analysis of prevalence and incidence data was conducted. Clearance and persistence data were extracted. Sixty-six studies met the inclusion criteria. Meta-analysis demonstrated an overall prevalence of 7.7% for all types of HPV and 1.4% for high-risk HPV16. The overall incidence was 4.38 cases per 1000 person-months for all HPV types and 0.92 cases per 1000 person-months for HPV16. This systematic review and meta-analysis demonstrated that oral HPV infection has a lower prevalence and incidence than cervicogenital HPV infection in healthy individuals. Nonetheless, oral HPV is still an important concern, given its oncogenicity and the rising incidence of oropharyngeal cancer. Consistency of methodology will allow for better future comparisons, particularly of infection clearance and persistence.

Abstract
OBJECTIVE The present study aimed to investigate human papillomavirus (HPV) prevalence and identify risk factors for HPV detection in urine samples among heterosexual men attending urological clinics. MATERIALS AND METHODS Spot urine samples including initial stream were collected from 845 participants, and the cell pellets were preserved into liquid-based cytological solution. After DNA extraction from each sample, HPV-DNA amplification and genotyping were performed using Luminex multiplex polymerase chain reaction. Participants completed a questionnaire on their age, education, smoking status, sexuality, age of sexual debut, marital status, and present history of sexually transmitted infections. RESULTS Data from 803 patients were included in the analysis. Overall HPV and high-risk (HR)HPV prevalence in urine samples were 6.2% and 3.1%, respectively. HPV and HR-HPV prevalences were the highest in men with urethritis, and were significantly higher than those without urethritis. HPV detection was the most common in men aged 40-49 years, although significant detection differences were not age-related. Urethritis was an independent risk factor for HPV detection from urine samples, with an odds ratio (OR) of 4.548 (95%CI; 1.802-11.476) (p = 0.001). On the other hand, a sub-analysis excluding men with urethritis demonstrated that prostate cancer was a significant risk factor for HPV detection, with OR of 2.844 (95%CI; 1.046-7.732) (p = 0.0410), whereas was not a significant risk for HR-HPV detection in urine samples. CONCLUSION Prostate cancer may represent a risk factor for HPV detection in the urine of men without urethritis. REGISTRATION OF CLINICAL TRIALS The authors did not register to Clinical Trial because this is observational and cross-sectional study.

Abstract
Chlamydia trachomatis (CT), an obligate intracellular bacterium, requires living cells to replicate. Half of men infected with CT are asymptomatic. CT infection can persist for up to four years within couples and affect their fertility. Chlamydia infection in men acts as a reservoir for transmission to women and can cause urinary tract inflammation, sperm DNA damage, and acute epididymitis. Semen samples from 1080 subfertile patients with normal and abnormal spermograms were examined to detect the presence of CT. An ELISA test was used to detect the presence of anti-CT IgA in these patients' seminal plasma. CT infection was also confirmed by molecular investigation using specific primers. In order to evaluate the effect of CT infections on the DNA Fragmentation Index (DFI), 40 CT-infected cases and 20 CT-negative controls were analyzed by a Sperm Chromatin Structure Assay using flow cytometry. Among 1080 patients with poor sperm parameters, 155 (14.3%) patients were diagnosed with CT, 11% among those with semen abnormalities and 26% among those without semen abnormalities patients. The DFI was statistically higher in cases than in controls (p < 0.05). Given the prevalence of infection and also the high frequency of asymptomatic CT infection among infertile individuals with poor sperm parameters, screening for infection in these patients is essential in order to avoid adverse sequelae. We propose that the higher rate of DFI in CT-infected infertile men might be an underlying cause of their infertility and this warrants greater attention.

Abstract
BACKGROUND The present study investigated human papillomavirus (HPV) prevalence in anal and urine samples, and evaluated cytological findings among human immunodeficiency virus (HIV)-infected Japanese men who have sex with men (MSM). METHODS A total of 148 patients were enrolled. Anal and urine samples were collected from each participant, and a HPV-DNA test and genotyping were performed using flow-through hybridization. In addition, anal cytology was evaluated based on Papanicolaou staining. Questionnaires regarding lifestyle habits and sexual behavior were obtained. RESULTS The β-globin gene was positive in 131 (88.5%) anal samples and 139 (94.0%) urine samples. Among the β-globin-positive samples, the HPV prevalence in anal and urine samples was 80.9% and 30.9%, respectively. High-risk HPV (HR-HPV) was detected in 57.3% of anal samples and 20.9% of urine samples. Among 122 adequate cytological samples, anal cytological abnormalities were observed in 99 cases (81.1%). Anal cytological tests revealed that atypical squamous cells of an undetermined significance (ASCUS) were detected in 57 (46.7%) patients, followed by low-grade squamous intraepithelial lesions (SIL) in 35 (28.7%), high-grade SIL in five (4.1%), and atypical squamous cells cannot exclude high-grade SIL (ASC-H) in two (1.6%), respectively. The nadir counts of CD4-positive T-lymphocyte less than 200 μL and anal HR-HPV infection were independent risk factors for anal cytological atypia over ASC-H. CONCLUSIONS The present study demonstrated high HPV prevalence in the anus and urine, and showed a high incidence of anal cytological atypia associated with HR-HPV infections among HIV-infected MSM patients.

Abstract
CONCLUSION The detection of human papillomavirus (HPV)-DNA in oral rinse with auto-nested GP5+/GP6 + PCR is useful as a biomarker of oropharyngeal cancer. BACKGROUND This study aimed to determine the usefulness of oral rinse to detect HPV-DNA as a biomarker of HPV-positive oropharyngeal cancer (OPC). PATIENTS AND METHODS One hundred and ten patients with various head and neck diseases, including 19 patients with OPC, were enrolled. Oral rinse and tonsillar swab were collected, and auto-nested GP5+/GP6 + PCR for HPV-DNA was performed. For oropharyngeal cancer, p16 immunostaining was also conducted. RESULTS The rate of HPV-DNA detection in both oral rinse and tonsillar swab was significantly higher in OPC compared with non-OPC upper respiratory tract cancer and non-cancer diseases. HPV-DNA was detected in oral rinse in nine out of 12 p16-positive OPC cases, while none of the p16-negative OPC cases demonstrated detectable HPV-DNA. All p16-positive cases were also positive for HPV-DNA in tumor tissue. Based on p16 immunostaining, the sensitivity and specificity of HPV-DNA detection in oral rinse were 75% and 100%, respectively. Among eight of nine evaluable OPC cases positive for HPV-DNA in oral rinse at diagnosis, HPV-DNA was undetectable in oral rinse in seven cases after treatment.

Abstract
Ureaplasma urealyticum and U. parvum have been associated with genital infections. The purpose of this study was to detect the presence of ureaplasmas and other sexually transmitted infections in sexually active women from Brazil and relate these data to demographic and sexual health, and cytokines IL-6 and IL-1β. Samples of cervical swab of 302 women were examined at the Family Health Units in Vitória da Conquista. The frequency of detection by conventional PCR was 76·2% for Mollicutes. In qPCR, the frequency found was 16·6% for U. urealyticum and 60·6% U. parvum and the bacterial load of these microorganisms was not significantly associated with signs and symptoms of genital infection. The frequency found for Trichomonas vaginalis, Neisseria gonorrhoeae, Gardnerella vaginalis and Chlamydia trachomatis was 3·0%, 21·5%, 42·4% and 1·7%, respectively. Higher levels of IL-1β were associated with control women colonized by U. urealyticum and U. parvum. Increased levels of IL-6 were associated with women who exhibited U. parvum. Sexually active women, with more than one sexual partner in the last 3 months, living in a rural area were associated with increased odds of certain U. parvum serovar infection.

Abstract
The prevalence rates of Mycoplasma genitalium infections and coinfections with other sexually transmitted organisms and the frequency of a macrolide antibiotic resistance phenotype were determined in urogenital specimens collected from female and male subjects enrolled in a multicenter clinical study in the United States. Specimens from 946 subjects seeking care from seven geographically diverse clinical sites were tested for M. genitalium and for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis Sequencing was used to assess macrolide antibiotic resistance among M. genitalium-positive subjects. M. genitalium prevalence rates were 16.1% for females and 17.2% for males. Significant risk factors for M. genitalium infections were black race, younger age, non-Hispanic ethnicity, and female symptomatic status. Female M. genitalium infections were significantly more prevalent than C. trachomatis and N. gonorrhoeae infections, while the M. genitalium infection rate in males was significantly higher than the N. gonorrhoeae and T. vaginalis infection rates. The macrolide-resistant phenotype was found in 50.8% of females and 42% of males. These results show a high prevalence of M. genitalium single infections, a lower prevalence of coinfections with other sexually transmitted organisms, and high rates of macrolide antibiotic resistance in a diverse sample of subjects seeking care across a wide geographic area of the United States.

Abstract
In addition to traditional risk factors such as smoking habits and alcohol consumption, certain microbes also play an important role in the generation of head and neck carcinomas. Infection with high-risk human papillomavirus types is strongly associated with the development of oropharyngeal carcinoma, and Epstein-Barr virus appears to be indispensable for the development of non-keratinizing squamous cell carcinoma of the nasopharynx. Other viruses including torque teno virus and hepatitis C virus may act as co-carcinogens, increasing the risk of malignant transformation. A shift in the composition of the oral microbiome was associated with the development of oral squamous cell carcinoma, although the causal or casual role of oral bacteria remains to be clarified. Conversion of ethanol to acetaldehyde, a mutagenic compound, by members of the oral microflora as well as by fungi including Candida albicans and others is a potential mechanism that may increase oral cancer risk. In addition, distinct Candida spp. also produce NBMA (N-nitrosobenzylmethylamine), a potent carcinogen. Inflammatory processes elicited by microbes may also facilitate tumorigenesis in the head and neck region.

Abstract
This cross-sectional study investigated the prevalence, genotypes, and risk factors for human papillomavirus (HPV) infection in Hanoi, Vietnam. The study included 192 males (mean age, 32.9 years) with symptoms related to sexually transmitted infections (STI). Urinary, penile, and urethral samples were collected in April and May, 2014. HPV DNA was detected with PCR, performed with modified and/or original GP5(+)/GP6(+) primers. HPV genotypes were determined with a gene array assay. Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) DNA were detected with loop-mediated isothermal amplification. HPV DNA, NG, and CT were detected in 48 (25.0%), 23 (12.0%), and 41 (21.4%) patients, respectively. HPV DNA appeared in penile samples (21.0%, 39/186) more frequently than in urinary (3.1%, 6/191, P < 0.001) and urethral (9.4%, 18/192, P = 0.002) samples. Among patients with HPV, genotype prevalence was: HPV81 (22.9%), HPV52 (18.8%), HPV18 (16.7%), and HPV16 (6.3%). Multiple-type and high risk-type HPV infections were determined in 33.3% and 64.6%, respectively. Multivariate analysis showed a significant association of HPV infection in urethra with younger sexual debut age. HPV52 was the most prevalent high-risk HPV genotype, whereas HPV16 was less common in the male Vietnamese patients with STI-related symptoms. Younger sexual-debut age was a risk factor for HPV infection in urethra.

Abstract
BACKGROUND The role of Mycoplasma hominis and M. genitalium in urogenital tract infections remains unknown. Furthermore these mollicutes present a complex relationship with the host immune response. The role of inflammatory cytokines in infections also makes them good candidates to investigate bacterial vaginosis and mycoplasma genital infections. Therefore, the aim of this study was to detect the above-mentioned mollicutes by quantitative Polymerase Chain Reaction (qPCR) methodologies in vaginal swabs and dosage of cytokines. METHODS Vaginal swabs and peripheral blood were collected from 302 women, including healthy individuals. The molecular findings were correlated with some individual behavioral variables, clinical and demographic characteristics, presence of other important microorganisms in vaginal swabs, and levels of interleukin (IL)-1β and IL-6. RESULTS M. hominis and M. genitalium were detected in 31.8% and 28.1% of samples, respectively. The qPCR results were associated with clinical signs and symptoms of the infections studied. The frequency of Trichomonas vaginalis, Gardnerella vaginalis, Neisseria gonorrhoeae and Chlamydia trachomatis was 3.0%, 21.5%, 42.4%, and 1.7% respectively. Increased levels of IL-1β were associated with the presence of M. hominis and signs and/or symptoms of the genital infection of women studied. CONCLUSION IL-1β production was associated with the detection of M. hominis by qPCR. The sexual behavior of women studied was associated with the detection of mycoplasma and other agents of genital infections.

Abstract
Several recent studies described that high-risk human papillomavirus (HPV) infection could have a potential role in the development of malignancies other than cervical cancer, such as laryngeal carcinoma, penile carcinoma, and anal carcinoma. However, the etiological role of HPV infection in the pathogenesis of urinary tract has not been clarified. Many epidemiological studies demonstrated that HPV infections frequently occur in the external genitalia through sexual contact; however, it was reported that HPV infection could also occur in the urinary tract, including the urethra and urinary bladder. Some morphological changes of cells associated with HPV infection and mild atypical cells, suspected to be intraneoplasia, were seen in HPV-positive samples obtained from the urinary tract. Some clinical studies and meta-analysis have indicated that HPV infection is likely to have a certain etiological correlation with the development of bladder carcinoma, although its prevalence may vary according to HPV type, study population, region, histological type, detection methods, and other variables. According to the results of previous studies, the prevalence of HPV greatly widely varies in cases of bladder carcinoma. Further research by case-control or large-scales studies is thus required to reach a more definite conclusion.

Abstract
Oral HPV infection, the cause of most oropharyngeal cancer in the U.S., is not well studied among high-risk young adults. Men (n = 340) and women (n = 270) aged 18–25 years attending Baltimore County STD clinics were recruited if they declined HPV vaccination. Each participant had a 30-second oral rinse and gargle sample tested for 37 types of HPV DNA, and a risk-factor survey. Factors associated with prevalent infection were explored using log binomial regression. Men had higher prevalence of any oral HPV (15.3% vs. 7.8%, p = 0.004) and vaccine-type oral HPV (i.e., HPV16/18/6/11: 5.0% vs. 1.1%, p = 0.007) infection than women. In multivariate analysis, male gender (aPR = 1.93, 95% CI = 1.10–3.39), number of recent oral sex partners (p-trend = 0.013) and having ever performed oral sex on a woman (aPR = 1.73, 95% CI = 1.06–2.82) were associated with increased oral HPV prevalence. Performing oral sex on a woman may confer higher risk of oral HPV acquisition than performing oral sex on a man.
