Abstract
Few studies focused on human papillomavirus (HPV) in male patients. This study aimed to explore the detection rate and genotyping of HPV among male patients in Beijing to provide a reference for formulating prevention strategies for HPV infection. The cross-sectional study was conducted in Beijing Chaoyang Hospital from November 2015 to March 2023. It covered male patients from the urology and dermatology departments. Fifteen high-risk HPV genotypes were detected by the multiplex real-time polymerase chain reaction method. The overall detection rate of HPV was 25.19% (1288/5114, 95% confidence interval [CI] 24.00%-26.38%), of which the single infection rate was 16.99% (869/5114, 95% CI 15.97%-18.05%) and the co-infection rate was 8.19% (419/5114, 95% CI 7.46%-8.98%). The detection rate of HPV was 40.77% (521/1278), 35.58% (58/163), 32.69% (101/309), 31.91% (60/188), 12.63% (299/2367), and 32.35% (131/405) among male patients with balanitis, warts, rash, urethritis, prostatitis, and other urinary inflammation, respectively (P < 0.001). The top five HPV genotypes were HPV-52, HPV-58, HPV-16, HPV-51, and HPV-66. After the first positive HPV test, the proportion of male patients who turned negative was 22.47% within 3 months, 26.40% within 3-6 months, 24.72% within 6-12 months, 17.98% within 12-24 months, and 8.43% more than 24 months. The detection rate of HPV was high among male patients from the urology and dermatology departments in Beijing, which should be considered to develop HPV vaccines with better prevention effects.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is defined as urologic pain or discomfort in the pelvic region, associated with urinary symptoms and/or sexual dysfunction, lasting for at least 3 of the previous 6 months. The rate of symptoms related to prostatitis has a mean prevalence of 8-8.2%. CP/CPPS is most frequent in men younger than 50 years, among whom it is the most common urologic diagnosis. In the last decades, many studies have been published on CP/CPPS and its association with male infertility. The pathophysiologic relation between CP/CPPS and male infertility involves several aspects, which are not well studied yet. A reduction in semen parameters has been demonstrated in patients with CP/CPPS, and several mechanisms have been proposed to represent putative pathophysiological links between CP/CPPS and infertility, including male accessory gland inflammation, metabolic syndrome, inflammatory bowel disease, HPV co-infection and autoimmunity. In light of this evidence, a multidisciplinary approach is advocated for patients with known CP/CPPS, and particular attention is needed for male patients of infertile couples in order to evaluate male accessory glands correctly. In addition, it is advisable that future studies dealing with the treatment of CP/CPPS take into consideration all the different pathophysiological aspects implicated.

Abstract
BACKGROUND Infertility affects one couple out of six worldwide. Male infertilty can result from congenital or acquired factors, of which pathogens that reach the genital tract through sexual contact or blood dissemination. The impact of major viral, bacterial and parasitic infections on the male genital tract and fertility has been summarized. RESULTS AND CONCLUSIONS A systematic review of articles published in the Google Scholar and PubMed databases was conducted. It turns out that viruses, as well as bacteria and parasites are major inducers of male genital tract infections and ensuing infertility through damage to the organs and subsequent loss of function and/or through direct damage to the sperm cells. Moreover, not only male infertility results from such infections but these can also be transmitted to women and even to the offspring, thus highlighting the need to efficiently detect, treat and prevent them.

Abstract
The assessment and management of urologic chronic pelvic pain syndrome (UCPPS), is controversial. It is classified by voiding symptoms, pelvic pain, and bladder pain, which is weekly treated, weekly understood, and bothersome. In the aspect of clinical efforts and research to help people with this syndrome have been hampered by the deficiency of a widely reliable, accepted, and a valuable tool to evaluate the patient symptoms and quality of life (QoL) impact. However, the etiology comes into sight is multifactorial, and available treatment options have been imprecise considerably in present years. We compiled the published literature on the assessment of the syndrome, a tentative role of pharmacological and non-pharmacological (conservative, alternative, and invasive therapy) interventions in eradicating the disease as well as improving symptoms. The previously published literature on animal models has established the association of immune systems in the etiology, pathogenesis, and progression of the disease. The UPOINT system for clinical phenotyping of UCPPS patients has six predefined domains that direct multimodal therapy, which would lead to significant symptom improvement in the medical field. The narrative review aims to scrutinize the fluctuating scientist's views on the evaluation of patient and multimodal treatment of the UPOINT system.

Abstract
Purpose Because of the insufficient efficacy of the current treatment of chronic bacterial prostatitis (CBP), it is justified to search for a more effective antibiotic therapy (ABT). Materials and Methods This single-centre prospective observational comparative study was conducted in 2012 to 2019 (patients: 60 men with CBP; age: 20–45 y). The clinical examination was performed on admission and at 1, 3, 6, or 12 months. All patients underwent the Meares–Stamey test to obtain expressed prostatic secretion (EPS) and/or post-massage urine (PMU) samples for extended bacteriological examination. The patients were randomly divided into 2 treatment groups (30/30 patients): group I, fluoroquinolones (FQs); group II, a combination of FQs with cephalosporins/macrolides with a treatment duration of 1 month. Results Patients of both groups had severe symptomatic CBP with an average duration of 4 years. Twenty-three microorganisms (15 aerobes, 9 anaerobes) were identified in PMU. At 3 months follow-up, a positive clinical effect was noted in both groups, which was significant (p<0.05) only in group II concerning NIH-CPSI questionnaire, leukocyturia, prostate volume, maximum urine flow, and decreased pathospermia. At 6 months follow-up, in group II the frequency of Escherichia coli and Enterococcus spp. decreased significantly. In group I aerobes changed only insignificantly from the initial level, but anaerobes increased significantly. In group II the titers of both, aerobes and anaerobes, were significantly lower (p<0.05) at 6 months follow-up as compared to initial values. Conclusions ABT targeting all taxa in EPS/PMU is a more effective alternative to standard therapeutic regimens for CBP.

Abstract
BACKGROUND Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a frequent disease affecting men of every age and accounting for a great number of consultations at urology departments. Previous studies suggested a negative impact of CP/CPPS on fertility. As increasing attention has been attributed to additional aspects, such as sperm DNA integrity and sperm protein alterations, besides the WHO standard semen analysis when assessing male fertility, in this prospective study, we aimed to further characterize the fertility status in CP/CPPS patients with a focus on these parameters. METHODS Sperm DNA fragmentation measured by sperm chromatin structure assay (SCSA) and protamine 1 to protamine 2 mRNA ratio assessed by RT-qPCR were analyzed along with conventional ejaculate parameters and inflammatory markers in 41 CP/CPPS patients and 22 healthy volunteers. RESULTS We found significant differences between the groups concerning multiple conventional ejaculate parameters. A significant increase in sperm DNA fragmentation was shown in CP/CPPS patients with association to other sperm parameters. The majority of CP/CPPS patients exhibited protamine mRNA ratios out of the range of regular fertility. CONCLUSIONS This is a pioneering study with a strong practical orientation revealing that CP/CPPS leads to increased sperm DNA damage and changes in sperm protamine levels, emphasizing an unfavorable impact of CP/CPPS on fertility.

Abstract
Background This study aimed to investigate the specific vaginal microbiome in the differential diagnosis of endometriosis/adenomyosis (EM/AM)-associated chronic pelvic pain (CPP) from other types of CPP, and to explore the role of the vaginal microbiome in the mechanism of EM/AM-associated CPP. Methods We recruited 37 women with EM/AM-associated CPP, 25 women with chronic pelvic pain syndrome (CPPS) without EM/AM, and 66 women without CPPS into our study. All of the participants were free from human papillomavirus (HPV) infection. Sequencing of barcoded 16S rRNA gene fragments (V4) was used to determine the vaginal microbiome composition on the Illumina HiSeq2500 System. Taxonomic and functional bioinformatics analyses were performed using t-test, linear discriminant analysis effect size (LEfSe), MetaStat, and PICRUSt algorithms. Results At the species level, EM/AM-associated CPP was found to be associated with a predominance of Clostridium butyricum, Clostridium disporicum, Alloscardovia omnicolens, and Veillonella montpellierensis, and a concomitant paucity of Lactobacillus jensenii, Lactobacillus reuteri, and Lactobacillus iners. When the relative abundance of Clostridium disporicum was over 0.001105% and that of Lactobacillus reuteri was under 0.1911349%, the differential diagnostic sensitivity and specificity were 81.08% and 52.0%, respectively. When serum CA125 was combined, the sensitivity increased to 89.19%, but the specificity remained at 52.0%. The PICRUSt results identified 7 differentially regulated pathways within the 3 groups that may be of relevance. Conclusions Compared to that of CPPS patients without EM/AM and women without CPPS, the vaginal microbiome of patients with EM/AM-associated CPP shows significantly higher alpha (phylogenetic) diversity, as well as higher counts of Clostridium butyricum, Clostridium disporicum, Alloscardovia omnicolens, and Veillonella montpellierensis. These differences in the vaginal microbiome may interfere with local functional pathways, which could provide a direction for innovative metabolite-specific targeted treatment. The combination of vaginal biomarkers and serum CA125 may provide an original method to differentiate EM/AM-associated CPP.

Abstract
INTRODUCTION The role of Ureaplasma spp. (UPs) in the pathogenesis of chronic prostatitis is debated. The lithogenic potential of UPs could be a risk factor for the development of chronic prostatitis. METHODS A total of 143 patients with identification of UPs were retrospectively selected from a database including patients with prostatitis-like symptoms who were studied according to the same protocol including clinical, microbiological and microscopic evaluation, and transrectal prostate ultrasound. A control group of patients with negative UPs was considered including 393 with chronic bacterial prostatitis (CBP), 42 patients with Chlamydia trachomatis (CT), and 781 patients with chronic pelvic pain syndrome. UPs and Mycoplasma hominis (MH) were identified using a semiquantitative assay. RESULTS Calcifications were observed more frequently in patients with UPs (64%) than in patients with CBP without UPs (39%), CT infection (37%), and chronic pelvic pain syndrome (29%) (p < 0.0001). UPs were isolated in VB1 alone in 35 patients (urethral UPs), in expressed prostatic secretion (EPS) or post-massage urine (VB3) or sperm in 77 patients (prostatic UPs) and associated with other pathogens in 31 patients (associated UPs). Calcifications were more frequent in prostatic UPs (71%) and associated UPs (73%) than in urethral UPs (34%). Mean NIH-CPSI scores were not significantly different between groups, although mean WBC counts of sperm of patients with urethral UPs were significantly lower than in patients with prostatic UPs (p = 0.000) and associated UPs (p = 0.002). CONCLUSIONS UPs identification in the urogenital fluids is related to higher rates of prostate calcifications. The ability of UPs to promote the formation of calcifications could be related to the chronicization of prostate infection. In particular, the presence of UPs in VB3/EPS/sperm is associated with higher rates of calcifications and high WBC sperm counts, suggesting a partial or full causative role of UPs in the pathogenesis of this disease.

Abstract
Cancer is a leading public health issue that accounts for million deaths around the world every year. Human cancers contain over 100 types, which are categorized into different groups. Adenocarcinoma is one of those categories of cancer that begins from the glans and involves various tissues such as lung, esophagus, pancreas, prostate and colorectal. A range of risk factors has been identified for the development and progression of adenocarcinomas. One of these risk factors are viruses that serves special mechanisms to affect important host cell factors and tumorigenic pathways, contributing in development and promotion of adenocarcinomas. Here, we summarized the main viruses and their mechanisms implicated in the course of various adenocarcinomas development.

Abstract
Introduction The aim of the study was to evaluate the frequency of occurrence of Chlamydia trachomatis (C.t.) DNA in the prostate material in the group of individuals with the chronic prostatitis. Material and methods The study included 65 males aged between 47 and 68 years of age, reporting for transrectal prostate biopsy because of the elevated serum prostate-specific antigen concentration and/or abnormalities detected in prostate palpation per rectum. The urethral smear collection was performed in all the patients in order to detect C.t. DNA. After that, the transrectal prostate biopsy was performed (histopathology tests, C.t. DNA). Additionally, the levels of anti-C.t. IgG antibodies and anti-C.t. IgA antibodies were checked in the serum. The DNA isolation from prostate specimens was conducted with the use of the Chelex method, while the C.t. DNA detection - with the ligase chain reaction. Specific antibodies were detected with the use of the ELISA method. Results C.t. DNA in the prostate gland was found in 7 out of 65 men (10.8%). In urethral smear, C.t. was found in none of the individuals. Anti-C.t. IgA antibodies were detected in the serum of 16/65 (24.6%), while anti-C.t. IgG antibodies in 6/65 (9.2%) of the examined males. IgA antibodies were found in two and IgG in one out of the 7 men who had C.t. infection in the prostate. Conclusions The presence of C.t. DNA in the prostate gland may be indicative of the role of chlamydia in the development of chronic prostatitis.

Abstract
It is hypothesised that high risk for cancer human papillomaviruses (HPVs) have a causal role in prostate cancer. In 26 case control studies, high risk HPVs have been identified in benign and prostate cancers. High risk HPVs were identified in 325 (22.6%) of 1284 prostate cancers and in 113 (8.6%) of 1313 normal or benign prostate controls (p = 0.001). High risk HPVs of the same type have been identified in both normal and benign prostate tissues prior to the development of HPV positive prostate cancer. High risk HPVs can be associated with inflammatory prostatitis leading to benign prostate hyperplasia and later prostate cancer. Normal human prostate epithelial cells can be immortalised by experimental exposure to HPVs. HPVs are probably sexually transmitted. The role of HPVs in prostate cancer is complex and differs from HPVs associated cervical cancer. HPV infections may initiate prostate oncogenesis directly and influence oncogenesis indirectly via APOBEC enzymes. HPVs may collaborate with other pathogens in prostate oncogenesis. Although HPVs are only one of many pathogens that have been identified in prostate cancer, they are the only infectious pathogen which can be prevented by vaccination. A causal role for HPVs in prostate cancer is highly likely.

Abstract
Background: There is growing evidence showing a putative association between high-risk human papillomavirus (HR-HPV) infection and an increased risk of PCa.Objective: The aim of the current meta-analysis was to evaluate the association between HPV infection and PCa risk.Methods: This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. We included all studies on HPV DNA or antibodies detected in biopsy tissues or sera. Available data were extracted from the article, including means and standard deviations in all case-control groups.Results: Thirty studies that investigated the link between HPV-16 and -18 were identified as eligible for this systematic review and meta-analysis, including a total of 6321 participants. The pooled OR showed increased risk of PCa (OR =1.37; p < .01) in men positive for HPV-16. There were seven studies with 2391 PCa cases and 4059 controls investigating the association between HPV-18 infection and PCa risk. Significant heterogeneity between study was found in the pooled analyzes. The pooled OR did not show increased risk of PCa (OR =0.80; p = .49) in men positive for HPV-18.Conclusions: This meta-analysis suggests that HPV-16 infection could represent a risk factor for PCa, whereas we found no such association for HPV-18. Further well-conducted studies could be useful to confirm this conclusion.

Abstract
The male genital tract (MGT) is the target of a number of viral infections that can have deleterious consequences at the individual, offspring, and population levels. These consequences include infertility, cancers of male organs, transmission to the embryo/fetal development abnormalities, and sexual dissemination of major viral pathogens such as human immunodeficiency virus (HIV) and hepatitis B virus. Lately, two emerging viruses, Zika and Ebola, have additionally revealed that the human MGT can constitute a reservoir for viruses cleared from peripheral circulation by the immune system, leading to their sexual transmission by cured men. This represents a concern for future epidemics and further underlines the need for a better understanding of the interplay between viruses and the MGT. We review here how viruses, from ancient viruses that integrated the germline during evolution through old viruses (e.g., papillomaviruses originating from Neanderthals) and more modern sexually transmitted infections (e.g., simian zoonotic HIV) to emerging viruses (e.g., Ebola and Zika) take advantage of genital tract colonization for horizontal dissemination, viral persistence, vertical transmission, and endogenization. The MGT immune responses to viruses and the impact of these infections are discussed. We summarize the latest data regarding the sources of viruses in semen and the complex role of this body fluid in sexual transmission. Finally, we introduce key animal findings that are relevant for our understanding of viral infection and persistence in the human MGT and suggest future research directions.

Abstract
Purpose Because of the inconsistent symptoms associated with Ureaplasma infections, their clinical significances in genitourinary tracts are under debate. Therefore, we evaluated the presence of Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) in urine samples and examined their associations with chronic prostatitis (CP) through a case and control study. Materials and Methods We included 696 nonchlamydial nongonococcal (NCNG) urine samples from men; 350 were categorized into non-inflammatory CP, 88 in inflammatory CP, and 258 in non-CP group. We amplified a region in the Ureaplasma urease areas from these samples and determined their biovars using the Sanger method. Results Among the NCNG population, the rates of UU, UP, and non-UU/UP were 3.88%, 6.46%, and 89.66%, respectively. The overall infection rates of non-CP, inflammatory CP, and non-inflammatory CP groups were 4.15%, 6.10%, and 3.65% in UU (p=0.612) and 6.85%, 7.22%, and 6.50% in UP (p=0.968), respectively. UU infection increased the risk of white blood cell (WBC) counts (≥5) in urine (p=0.005). In contrast, UP infections did not increase the risks of urethritis. Re-analysis from the 633 men who were excluded from urethritis effects did not reveal the associations between UU infection and the clinical characteristics of CP. Furthermore, the profiles from the National Institutes of Health-Chronic Prostatitis Symptom Index questionnaire and WBC counts in expressed prostatic secretion were similar among the non-CP and the two CP groups in each Ureaplasma infection. Conclusions We found that UU may induce male urethritis. However, Ureapalsma species in urine were not definitively associated with the occurrence of CP.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is associated with urinary tract symptoms and hormonal imbalances amongst others. The heterogeneous clinical presentation, unexplored molecular background and lack of prostate biopsies complicate therapy. Here, using liquid biopsies, we performed a comprehensive translational study on men diagnosed with CP/CPPS type III (n= 50; median age 39.8, range 23-65) and age-matched controls (n= 61; median age 36.8, range 20-69), considering biochemical parameters of blood and ejaculates, and epigenetic regulation of the estrogen receptor genes (ESR1 and ESR2) in leukocytes isolated from blood (systemic regulation) and in somatic cells isolated from ejaculates (local regulation). We found elevated 17β-estradiol (E2) levels in seminal plasma, but not in blood plasma, that was significantly associated with CP/CPPS and impaired urinary tract symptoms. In ejaculated somatic cells of CP/CPPS patients we found that ESR1 and ESR2 were both significantly higher methylated in CpG-promoters and expressionally down-regulated in comparison to controls. Mast cells are reported to contribute to CP/CPPS and are estrogen responsive. Consistent with this, we found that E2 -treatment of human mast cell lines (HMC-1 and LAD2) resulted in altered cytokine and chemokine expression. Interestingly, in HMC-1 cells, possessing epigenetically inactivated ESR1 and ESR2, E2 -treatment led to a reduced transcription of a number of inflammatory genes. Overall, these data suggest that elevated local E2 levels associate with an epigenetic down-regulation of the estrogen receptors and have a prominent role in CP/CPPS. Investigating E2 levels in semen could therefore serve as a promising biomarker to select patients for estrogen targeted therapy.

Abstract
BACKGROUND We examined whether urine reflux into the prostate can induce prostatic inflammation in a rat and evaluated the effect of α1-adrenoreceptor antagonist. METHODS Experiment 1: Male Sprague-Dawley rats were injected with 500 µl of Evans Blue through the urethral orifice. Intravesical pressure was measured, and the prostate was excised to evaluate urine reflux. Experiment 2: Rats were injected with 500 µl urine or saline (control) from the urethral orifice. Silodosin (200 µg/kg/day) was administered to the silodosin group. We evaluated histopathology, the expression of proinflammatory cytokines and oxidative stress markers of the prostate on day 7, after assessing the prostatic microcirculation and cystometrogram. RESULTS Experiment 1: The histopathology showed that Evans Blue instilled through the urethral orifice entered the prostatic ducts. Intravesical pressure during Evans Blue instillation was 47.7 ± 1.6 cmH2 O (mean ± standard error). Experiment 2: On day 7 after urine instillation through the urethral orifice, histopathology showed infiltrated inflammatory cells in the peri-glandular stroma. Inflammation-associated proteins (IL-1α, IL-1β, IL-6, and TNFα) were upregulated in the urine-instilled rats but not in the silodosin group. Erythrocyte speed on the prostatic surface, immunostaining for hypoxyprobe, and quantification of oxidative stress markers (MDA and HIF-1α) demonstrated prostatic hypoxia in the urine-instilled rats, which was ameliorated in the silodosin group. Cystometrogram revealed a shorter intercontraction interval in the urine-instilled rats, which was prolonged in the silodosin group. CONCLUSIONS Urine reflux into the prostatic duct induces abacterial prostatitis. Silodosin relieved prostatic inflammation and bladder overactivity by increasing microcirculation in the prostate.

Abstract
Background: Type-III chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common type of prostatitis. Patients and methods: We ascertained the effect of ‘thermobalancing’ therapy (TT; using Dr Allen’s therapeutic device (DATD)) on CP/CPPS. We measured National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores, prostatic volume (PV), and maximum urinary flow rate (Qmax) in one group of 45 patients who underwent TT and a control group that did not have TT, and compared these parameters between groups. Results: Baseline evaluation (pretreatment) of both groups showed no significant difference with regard to age, NIH-CPSI score, PV or Qmax. Pain score decreased in both groups but, in the treatment group, the difference between scores was considerably higher (8.72:1) than that of the non-treatment group. TT decreased quality of life (QoL) significantly whereas, in the control group, it decreased QoL slightly. TT reduced PV significantly whereas, in the control group, PV increased. TT increased Qmax significantly in CP/CPPS patients whereas, in the control group, TT did not elicit a significant change in Qmax. Conclusions: Six-month TT with DATD: (a) reduces CP/CPPS symptoms and improves QoL; (b) reduces PV; (c) increases Qmax. TT could be effective treatment for CP/CPPS.

[PMID: 26970449 DOI: 10.1016/j.urology.2016.02.043] [Citation(s) in RCA: 88] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Revised: 02/10/2016] [Accepted: 02/26/2016] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To study the urinary microbiome of patients with Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) compared with controls. METHODS We identified 25 patients with CP/CPPS and 25 men who were either asymptomatic or only had urinary symptoms. Midstream urine was collected. Symptom severity was measured with the National Institutes of Health Chronic Prostatitis Symptom Index and clinical phenotype with UPOINT. Total DNA was extracted from the urine pellet and bacterial-specific 16Sr-DNA-capture identified by MiSeq sequencing. Taxonomic and functional bioinformatic analyses used principal coordinate analysis (PCoA)/MacQIIME, LEfSe, and PiCRUSt algorithms. RESULTS Patients and controls were similar ages (52.3 vs 57.0 years, P = .27). For patients, median duration was 48 months, mean Chronic Prostatitis Symptom Index was 26.0, and mean UPOINT domains was 3.6. Weighted 3D UniFrac PCoA revealed tighter clustering of controls distinct from the wider clustering of cases (P = .001; α-diversity P = .005). Seventeen clades were overrepresented in patients, for example, Clostridia, and 5 were underrepresented, eg, Bacilli, resulting in predicted perturbations in functional pathways. PiCRUSt inferred differentially regulated pathways between cases and controls that may be of relevance including sporulation, chemotaxis, and pyruvate metabolism. PCoA-derived microbiomic differences were noted for neurologic/systemic domains (P = .06), whereas LEfSe identified differences associated with each of the 6 clinical features. CONCLUSION Urinary microbiomes from patients with CP/CPPS have significantly higher alpha(phylogenetic) diversity which cluster differently from controls, and higher counts of Clostridia compared with controls, resulting in predicted perturbations of functional pathways which could suggest metabolite-specific targeted treatment. Several measures of severity and clinical phenotype have significant microbiome differences.

Abstract
Despite the increasing number of studies conducted recently to evaluate the association between HPV infections and the risk of prostate cancer, the results remain inconclusive. Furthermore, the prevalence and distribution of overall and individual HPV types worldwide in prostate cancer has not been reported until now. Therefore, we estimated the prevalence of HPV in prostate cancer by pooling data of 46 studies with 4919 prostate cancer cases, taking into account the heterogeneity of major related parameters, including study region, specimen type, HPV DNA source, detection method, publication calendar period and Gleason score. Moreover, we tested the association of HPV infections with prostate cancer risks by a meta-analysis of 26 tissue-based case-control studies. We found that the prevalence of HPV infection was 18.93% (95% CI = 17.84-20.05%) in prostate cancer cases, and most of which were high-risk HPV types (17.73%, 95% CI = 16.52-18.99%). The prevalence varied by region, PCR primers used, publication calendar period and Gleason score. Our study also showed a significantly increased risk of prostate cancer with the positivity of overall HPV detected in prostate tissues (OR = 1.79, 95% CI = 1.29-2.49) and revealed the geographic variation of association strength (P < 0.001). In conclusion, HPV infections may contribute to the risk of prostate cancer.

Abstract
OBJECTIVE Until recently the generally accepted paradigm implied that urine of healthy people is sterile. In the present study, urine of healthy subjects was investigated by extended bacteriological methods. MATERIAL AND METHODS Three midstream urine samples from 52 healthy subjects each (24 females, 28 males; 18-25 years of age) were investigated by an extended set of culture media for identification of facultative aerobic (FAB) and nonclostridial anaerobic bacteria (NCAB). Ward's method (Euclidean distance) was used for similarity analysis. RESULTS The bacterial count of FAB in urine was usually low (≤ 10(2) colony-forming units/ml) in both groups. In contrast, the bacterial count of NCAB was higher (≥ 10(3) colony-forming units/ml), at least in some species, with significant differences between genders. The average number of bacterial species found was 5.8 in female and 7.1 in male urine. Half of the females were assigned to a specific 'female' microbial spectrum, different from that of males. In the mixed-gender clusters, the males showed a greater similarity among themselves. CONCLUSIONS As also shown by other investigators, urine of healthy people is normally not sterile. The role of the routinely not cultivated bacteria in healthy and diseased subjects needs to be established. It may alter the diagnostics of infectious and inflammatory diseases of the urogenital tract.

Abstract
Prostatic involvement in granulomatosis with polyangiitis (GWP), formerly known as Wegener's granulomatosis, is rare, mostly arising in the context of systemic involvement. Prostatic involvement as the first manifestation of this systemic disease is exceptionally rare. We hereby present the case of a 41-year-old male patient who underwent transurethral prostate resection for what was initially diagnosed as suppurative, focally necrotizing prostatitis. Prolonged postoperative fever that did not respond to various treatments, as well as the subsequent appearance of a left pleural effusion, a left upper pulmonary lobe lesion and cutaneous nodules, led to a reevaluation of histological slides which, along with the determination of serum c-ANCA/anti-PR3 antibody levels, established the diagnosis of GWP. Physicians, and especially urologists and infectious diseases specialists, should be aware of this rare association and consider GWP in the event of nonresolving prostatitis, especially when characteristic symptoms from other systems appear.

Detection and quantification of human herpes viruses types 4-6 in sperm samples of patients with fertility disorders and chronic inflammatory urogenital tract diseases. Andrology 2014; 2:687-94.

Abstract
Acute and chronic infections of the seminal tract are among the most common causes of male infertility. As at least half of male infertility cases are classified as idiopathic, some of these cases might be attributed to asymptomatic infection. The detection and quantification of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human herpes virus type 6 (HHV-6) DNA in semen samples were performed. A total of 232 patients were divided into five groups: (i) infertile men with varicocoele; (ii) men with idiopathic infertility; (iii) infertile men with chronic inflammatory urogenital tract diseases (IUTD); (iv) fertile men with IUTD and (v) men whose partners had a history of pregnancy loss. In the study population, the prevalence of viral DNA was 17.7, 3.4% for EBV, 5.2% for CMV, 6.5% for HHV-6, 0.43% for EBV + CMV, 0.87% for EBV + HHV-6 and 1.3% for CMV + HHV-6. The median viral loads for EBV, CMV and HHV-6 were 500, 2250 and 250 copies/mL respectively. Of the sperm cell fractions, derived from infected samples 87.5% contained viral DNA. No association between EBV and fertility disorders or IUTD was found. CMV detection was much higher in the group of patients with infertility and concomitant IUTD compared with the other groups combined (18.5% vs. 5.4%, p = 0.03) and associated with reduced sperm cell count (39.5 × 10(6) /mL vs. 72.5 × 10(6) /mL, p = 0.036). Immunostaining of spermatozoa from infected samples and in vitro-infected cells detected CMV in sperm heads, tails and connecting pieces and revealed attachment to sperm membrane and intracellular localization. HHV-6 was the more common in fertile men with chronic IUTD than in the other groups combined (19% vs. 6.3%, p = 0.018) and had no effect on sperm parameters. The results suggest that both CMV and HHV-6 may contribute to the aetiology of IUTD and, moreover, CMV-associated IUTD can lead to male sterility.
