REVISTA ESPANOLA DE QUIMIOTERAPIA : PUBLICACION OFICIAL DE LA SOCIEDAD ESPANOLA DE QUIMIOTERAPIA 2019; 32:327-332. [PMID: 31271277 PMCID: PMC6719643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 04/14/2019] [Accepted: 05/14/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE Several studies have reported greater success of fertilisation by ART in couples who were not infected by Ureaplasma. Increased semen quality and better results have also been observed in couples who were treated with antibiotics to eradicate the infection. The aim of this study was to determine the prevalence of genital mycoplasmas in urine samples from male partners enrolled in the Assisted Reproduction Program (ARP) in our healthcare area so that, positive cases can be treated prior to the use of ART in order to increase the quality of semen, improve the embryo implantation rates and minimize the risk of adverse effects during pregnancy. METHODS This study included couples enrolled in the ARP during 2016. Mycoplasma detection was made using real-time PCR. In positive cases, both members of the couple were treated with antibiotics until eradication of the microorganism. The antibiotics used were: azithromycin, doxycycline, levofloxacin, moxifloxacin, and clindamycin. RESULTS Of the 205 men studied, 33 were positive: Ureaplasma urealyticum 15.1%, Mycoplasma hominis 3.9%. Eradication treatment with azithromycin failed in 50% compared to 10.2% for doxycycline. Of the 5 cases treated with levofloxacin, only 2 achieved elimination of U. urealyticum. CONCLUSIONS We consider that genital mycoplasma routine screening could be useful in order to increase the quality of semen which could simplify the in vitro fertilisation procedures and raise the success rate of embryo implantation and pregnancy, especially when fast, sensitive and specific technics as real time PCR are used.

Abstract
BACKGROUND Chronic inflammation and infections are associated with increased risk of prostate cancer development. There is considerable evidence that proves the interrelationship between bacterial/viral infections and carcinogenesis. Periodontitis is a chronic inflammatory disease triggered by gram-negative anaerobic bacteria. In this narrative review, we investigate the relationship between periodontal disease and prostate cancer by reviewing previous studies of the association and possible mechanisms that may explain this link. METHODS A comprehensive search for articles published was performed using the key words, "periodontal disease", "prostate disease", "prostate cancer", "prostatic inflammation". Thorough reviews of each study were conducted and assessed for eligibility, and data was summarized. RESULTS The role of inflammatory responses in the prostate as drivers of malignancy appears to be predisposed by periodontal pathogens and/or periodontitis inflammatory mediators. CONCLUSION Periodontal diseases might be associated with prostate cancer. However, the mechanism(s) explaining this relationship remains unclear and requires further elucidation.

Sci Rep 2016; 6:35737. [PMID: 27759111 PMCID: PMC5069632 DOI: 10.1038/srep35737] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Accepted: 09/22/2016] [Indexed: 01/09/2023] Open
Abstract
Alpha-blockers and antibiotics are most commonly used to treat chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in clinical practice. Currently, increasing evidence also suggests acupuncture as an effective strategy. This network meta-analysis intended to assess the comparative efficacy and safety of acupuncture, alpha-blockers and antibiotics for CP/CPPS. Twelve trials involving 1203 participants were included. Based on decreases in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score, a network meta-analysis indicated that electro-acupuncture (standard mean difference [SMD]: 4.29; 95% credible interval [CrI], 1.96-6.65), acupuncture (SMD: 3.69; 95% CrI, 0.27-7.17), alpha-blockers (SMD: 1.85; 95% CrI, 1.07-2.64), antibiotics (SMD: 2.66; 95% CrI, 1.57-3.76), and dual therapy (SMD: 3.20; 95% CrI, 1.95-4.42) are superior to placebo in decreasing this score. Additionally, electro-acupuncture (SMD: 2.44; 95% CrI, 0.08-4.83) and dual therapy (SMD: 1.35; 95% CrI, 0.07-2.62) were more effective than alpha-blockers in decreasing the total NIH-CPSI total score. Other network meta-analyses did not show significant differences between interventions other placebo. The incidence of adverse events of acupuncture was relatively rare (5.4%) compared with placebo (17.1%), alpha-blockers (24.9%), antibiotics (31%) and dual therapy (48.6%). Overall, rank tests and safety analyses indicate that electro-acupuncture/acupuncture may be recommended for the treatment of CP/CPPS.

Comparison of polymerase chain reaction and immunologic methods for the detection of nanobacterial infection in type-III prostatitis. Urology 2014; 84:731.e9-13. [PMID: 25168570 DOI: 10.1016/j.urology.2014.05.038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Revised: 05/11/2014] [Accepted: 05/29/2014] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To compare the results of polymerase chain reaction (PCR) and immunologic methods for the detection of nanobacteria (NB) in the expressed prostatic secretions (EPSs) of patients with type-III prostatitis. METHODS In total, 150 patients with type-III prostatitis for whom conventional clinical treatment had failed were selected from September 2009 to April 2010. The EPS of each patient was divided into 3 parts, which were used for PCR analysis, indirect immunofluorescence staining (IIFS), and culture and subsequent indirect immunofluorescence staining (CIIFS). RESULTS PCR analysis has a higher sensitivity than IIFS for the detection of NB in EPSs. Of 83 CIIFS-positive EPS samples, 79 (95.2%) were positive by PCR. Of 67 EPS samples that were negative by CIIFS, 60 (89.6%) were negative by PCR. The sensitivity of PCR for the detection of NB compared with the CIIFS method was 95.2%, with a specificity of 89.6%. The positive predictive value was 91.9%, and the negative predictive value was 93.8%. A comparative evaluation showed no statistically significant difference between PCR and CIIFS in the detection of NB in EPSs. A strong agreement in the positive and the negative results obtained by PCR and CIIFS for NB detection was found for all EPS samples. CONCLUSION PCR analysis has a higher sensitivity than IIFS for NB detection in type-III prostatitis. PCR can detect nanobacterial infection in type-III prostatitis equally well as CIIFS and offers significant advantages for the rapid, simple, and economical detection of nanobacterial infection in type-III prostatitis.

[PMID: 24462419 DOI: 10.1016/j.jiac.2013.07.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2013] [Revised: 07/05/2013] [Accepted: 07/18/2013] [Indexed: 12/31/2022]
Abstract
Roxithromycin is effective in the treatment of intracellular organisms, including chlamydia and mycoplasma, and exhibits anti-inflammatory and immunomodulatory effects on respiratory diseases. To explore the potential therapeutic benefit of roxithromycin in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), this study compared the effect of roxithromycin with ciprofloxacin and aceclofenac. A total of 75 patients with CP/CPPS were randomized to three groups in open-label: group 1, ciprofloxacin; group 2, aceclofenac; and group 3, roxithromycin. The patients were treated for 4 weeks and were subsequently followed for 12 weeks. Changes from baseline in the total and domain scores of the NIH Chronic Prostatitis Symptom Index (NIH-CPSI) were evaluated. The NIH-CPSI score decreased in the roxithromycin, ciprofloxacin, and aceclofenac groups to a similar degree. The NIH-CPSI initial and 12-week total scores were 20.3 and 10.0, respectively, in group 1; 23.6 and 14.3, respectively, in group 2; and 21.1 and 9.8, respectively, in group 3. The three treatment arms did not differ significantly with respect to the efficiency of treatment (p > 0.05). Compared to patients in groups 1 and 2, group 3 patients with Category IIIb disease exhibited favorable results upon follow-up 12 weeks after treatment. The International Prostate Symptom Score (IPSS), uroflowmetry, and post-void residual volume were equivalent between the groups. Roxithromycin exhibits similar or favorable effects on the improvement of CP/CPPS compared to ciprofloxacin and aceclofenac. Roxithromycin could be used as a new therapeutic agent for CP/CPPS. Further study of the immunomodulatory action of roxithromycin in CP/CPPS is required.

Abstract
INTRODUCTION AND OBJECTIVES Calcifying nanoparticles, also known as "nanobacteria," are very small bacteria-like structures (0.1-0.5 μm) with the ability to facilitate the precipitation and growth of calcium phosphate in pathological conditions and have been associated with aortic valve calcification. The status of nanobacteria is controversial; some have proposed that they are a new class of living organism while others describe calcifying nanoparticles as mineralo-fetuin complexes. The objective of the present study is to elucidate if calcifying nanoparticles are living entities, based on whether or not they have metabolic activity, a characteristic of life, irrespective of their composition. METHODS Calcifying nanoparticles were grown from 6 different valves randomly chosen among 84 consecutively explanted aortic valves, as described in the literature. The (1)H-NMR spectra were acquired from calcifying nanoparticles culture media to assess metabolic changes and the presence of 16sRNA in the culture media was investigated by real-time polymerase chain reaction. RESULTS After 6 weeks in culture, calcifying nanoparticles could be seen clearly attached to the surface of culture flasks. All samples were negative for 16sRNA, discarding the presence of known bacteria. (1)H-NMR spectra showed no difference between calcifying nanoparticles and 6-week-old sterile culture media maintained under the same conditions. CONCLUSIONS Our results show that calcifying nanoparticles cannot be considered as living organisms.

Abstract
The aim of this study was to assess the usefulness of PCR for diagnosis of Trichomonas vaginalis infection among male patients with chronic recurrent prostatitis and urethritis. Between June 2001 and December 2003, a total of 33 patients visited the Department of Urology, Hanyang University Guri Hospital and were examined for T. vaginalis infection by PCR and culture in TYM medium. For the PCR, we used primers based on a repetitive sequence cloned from T. vaginalis (TV-E650). Voided bladder urine (VB1 and VB3) was sampled from 33 men with symptoms of lower urinary tract infection (urethral charge, residual urine sensation, and frequency). Culture failed to detect any T. vaginalis infection whereas PCR identified 7 cases of trichomoniasis (21.2%). Five of the 7 cases had been diagnosed with prostatitis and 2 with urethritis. PCR for the 5 prostatitis cases yielded a positive 330 bp band from bothVB1 and VB3, whereas positive results were only obtained from VB1 for the 2 urethritis patients. We showed that the PCR method could detect T. vaginalis when there was only 1 T. vaginalis cell per PCR mixture. Our results strongly support the usefulness of PCR on urine samples for detecting T. vaginalis in chronic prostatitis and urethritis patients.

Abstract
BACKGROUND The purpose of this study was to examine the possible contribution of calcifying nanoparticles to the pathogenesis of placental calcification. METHODS Calcified placental tissues and distal tissue samples were collected from 36 confirmed placental calcification cases. In addition, 20 normal placental tissue samples were obtained as a control group. All the tissue samples were cultured using special nanobacterial culture methods. The cultured calcifying nanoparticles were examined by transmission electron microscopy (TEM), and their growth was monitored by optical density (OD) at a wavelength of 650 nm. 16S rRNA gene expression of the cultured calcifying nanoparticles was also isolated and sequenced. RESULTS Novel calcifying nanoparticles wrapped with electron-dense shells between 50 nm to 500 nm in diameter were observed in the extracellular matrix of calcified placental tissues. They were detected in placental villi and hydroxyapatite crystals, and contained "nucleic acid-like materials". After isolation and four weeks of culture, 28 of 36 calcified placental tissue samples showed white granular precipitates attached to the bottom of the culture tubes. OD(650) measurements indicated that the precipitates from the calcified placental tissues were able to grow in culture, whereas no such precipitates from the control tissues were observed. The 16S rRNA genes were isolated from the cultured calcifying nanoparticles and calcified placental tissues, and their gene sequencing results implied that calcifying nanoparticles were novel nanobacteria (GenBank JF823648). CONCLUSION Our results suggest that these novel calcifying nanoparticles may play a role in placental calcification.

Abstract
PURPOSE Our purpose was to conduct a screening test for urethritis or cervicitis as a sexually transmitted disease (STD) by using multiplex polymerase chain reaction(PCR) and to determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Ureaplasma urealyticum, Mycoplasma hominis, and Trichomonas vaginalis in asymptomatic people. MATERIALS AND METHODS From July 2010 to December 2010, 709 persons who came to the hospital for a general checkup were tested. Multiplex PCR assays were done with first voided urine samples or endocervical swabs by use of the Seeplex® STD6 ACE Detection kit. RESULTS The mean age in this study was 45.4±8.1 years. Among the 709 persons, 229 (32.3%) had a positive result for at least one microorganism, 48 (6.8%) had two different species, 6 (0.8%) had three different species, and 1 person had four different species. The overall prevalence of asymptomatic STDs such as urethritis or cervicitis was 7.1% (50/709). The prevalence rates of chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Ureaplasma urealyticum, Mycoplasma hominis, and Trichomonas vaginalis infection in asymptomatic persons were 5.6% (40/709), 0.4% (3/709), 0.3% (2/709), 22.1% (157/709), 11.6% (82/709), and 1.1% (8/709), respectively. CONCLUSIONS With only a single sample, we could identify the prevalence rates of six microorganisms and the overall proportion of urethritis or cervicitis in asymptomatic people. This proportion cannot be neglected; therefore, screening tests for sexually transmitted diseases such as urethritis or ervicitis should be recommended to asymptomatic people.
