Sodium Bituminosulfonate Used to Treat Rosacea Modulates Generation of Inflammatory Mediators by Primary Human Neutrophils. J Inflamm Res 2021; 14:2569-2582. [PMID: 34163212 PMCID: PMC8215909 DOI: 10.2147/jir.s313636] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 05/28/2021] [Indexed: 12/14/2022] Open
Abstract
Background Sodium bituminosulfonate is derived from naturally occurring sulphur-rich oil shale and is used for the treatment of the inflammatory skin disease rosacea. Major molecular players in the development of rosacea include the release of enzymes that process antimicrobial peptides which, together with reactive oxygen species (ROS) and vascular endothelial growth factor (VEGF), promote pro-inflammatory processes and angiogenesis. The aim of this study was to address the molecular mechanism(s) underlying the therapeutic benefit of the formulation sodium bituminosulfonate dry substance (SBDS), which is indicated for the treatment of skin inflammation, including rosacea. Methods We investigated whether SBDS regulates the expression of cytokines, the release of the antimicrobial peptide LL-37, calcium mobilization, proteases (matrix metalloproteinase, elastase, kallikrein (KLK)5), VEGF or ROS in primary human neutrophils. In addition, activity assays with 5-lipoxygenase (5-LO) and recombinant human MMP9 and KLK5 were performed. Results We observed that SBDS reduces the release of the antimicrobial peptide LL-37, calcium, elastase, ROS and VEGF from neutrophils. Moreover, KLK5, the enzyme that converts cathelicidin to LL-37, and 5-LO that produces leukotriene (LT)A4, the precursor of LTB4, were both inhibited by SBDS with an IC50 of 7.6 µg/mL and 33 µg/mL, respectively. Conclusion Since LTB4 induces LL-37 which, in turn, promotes increased intracellular calcium levels and thereby, ROS/VEGF/elastase release, SBDS possibly regulates the LTB4/LL-37/calcium – ROS/VEGF/elastase axis by inhibiting 5-LO and KLK5. Additional direct effects on other pro-inflammatory pathways such as ROS generation cannot be ruled out. In summary, SBDS reduces the generation of inflammatory mediators from human neutrophils possibly accounting for its anti-inflammatory effects in rosacea.

Andrology 2020; 9:115-144. [PMID: 32794312 DOI: 10.1111/andr.12886] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 07/09/2020] [Accepted: 08/07/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Male factor is attributable in up to 50% of cases of infertility. In vitro studies demonstrate that bacteria can negatively impact sperm function. The use of next-generation sequencing techniques has provided a better understanding of the human microbiome, and dysbiosis has been reported to impact health. Evidence regarding the impact of the semen microbiome on sperm function and fertility remains conflicting. MATERIALS AND METHODS A systematic search was conducted in accordance with the Preferred Reporting Items for Reviews and Meta-analysis (PRISMA) statement. The databases MEDLINE, OVID and PubMed were searched to identify English language studies related to the identification of bacteria in the semen of infertile and fertile men, between 1992 and 2019. Fifty-five observational studies were included, with 51 299 subjects. We included studies identifying bacteria using next-generation sequencing, culture or polymerase chain reaction. RESULTS The semen microbiome was rich and diverse in both fertile and infertile men. Three NGS studies reported clustering of the seminal microbiome with a predominant species. Lactobacillus and Prevotella were dominant in respective clusters. Lactobacillus was associated with improvements in semen parameters. Prevotella appeared to exert a negative effect on sperm quality. Bacteriospermia negatively impacted sperm concentration and progressive motility, and DNA fragmentation index (DFI; MD: 3.518, 95% CI: 0.907 to 6.129, P = .008). There was an increased prevalence of ureaplasma urealyticum in infertile men (OR: 2.25, 95% CI: 1.47-3.46). Ureaplasma urealyticum negatively impacted concentration and morphology. There was no difference in the prevalence of chlamydia trachomatis between fertile and infertile men and no significant impact on semen parameters. Enterococcus faecalis negatively impacted total motility, and Mycoplasma hominis negatively impacted concentration, PM and morphology. DISCUSSION AND CONCLUSIONS Ureaplasma urealyticum, Enterococcus faecalis, Mycoplasma hominis and Prevotella negatively impact semen parameters, whereas Lactobacillus appears to protect sperm quality. These findings may facilitate the development of novel therapies (eg probiotics), although the evidence regarding the impact of the seminal microbiome on fertility is inconclusive and further studies are needed to investigate this association.

Abstract
Chlamydia trachomatis (CT) is the most prevalent bacterial sexually transmitted infection in the world, with more than 100 million cases reported annually. While there have been extensive studies into the adverse effects that CT infection has on the female genital tract, and on the subsequent ability of these women to conceive, studies into the consequences on male fertility have been limited and controversial. This is in part due to the asymptomatic nature of the infection, where it is estimated that 50% of men with Chlamydia fail to show any symptoms. It is accepted, however, that acute and/or persistent CT infection is the causative agent for conditions such as urethritis, epididymitis, epididymo-orchitis, and potentially prostatitis. As with most infections, the immune system plays a fundamental role in the body’s attempts to eradicate the infection. The first and most important immune response to Chlamydia infection is a local one, whereby immune cells such as leukocytes are recruited to the site of infections, and subsequently secrete pro-inflammatory cytokines and chemokines such as interferon gamma. Immune cells also work to initiate and potentiate chronic inflammation through the production of reactive oxygen species (ROS), and the release of molecules with degradative properties including defensins, elastase, collagenase, cathespins, and lysozyme. This long-term inflammation can lead to cell proliferation (a possible precursor to cancer), tissue remodeling, and scarring, as well as being linked to the onset of autoimmune responses in genetically disposed individuals. This review will focus on the ability of the immune system to recognize and clear acute and persistent chlamydial infections in the male genital tract, and on the paradoxical damage that chronic inflammation resulting from the infection can cause on the reproductive health of the individual.

Abstract
This study was undertaken to determine the prevalence of Chlamydia trachomatis, Mycoplasmas, and Ureaplasmas in semen samples of the male partners of infertile couples and to investigate whether Chlamydia trachomatis could initiate apoptosis in human spermatozoa. A total of 85 males partners of infertile couples undergoing routine semen analysis according to World Health Organization guidelines were included. Specimens were examined for the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum and Ureaplasma parvum by Real time PCR (qPCR). Semen specimens were analysed for the appearance of apoptotic markers (sperm DNA fragmentation, activated caspase 3 levels, mitochondrial membrane potential (ΔΨm)) using flow cytometry. C. trachomatis, N. gonorrhoeae, U. urealyticum, M genitalium were detected in semen samples of 13 (15.2%), 5 (5.8%), 5 (5.8%) and 3 (3.5%) male partners of infertile couples, respectively. M. hominis and U. parvum were detected in semen sample of only one patient (1.1%). The semen of infertile men positive for C. trachomatis showed lower mean of semen count and lower rapid progressive motility (category [a]) of spermatozoa compared to uninfected men with statistically significances (p = 0.02 and p = 0.04, respectively). Flow cytometry analyses demonstrated a significant increase of the mean rate of semen with low ΔΨm and caspase 3 activation of infertile men positive for C. trachomatis compared to uninfected men (p = 0.006 and p = 0.001, respectively). DNA fragmentation was also increased in sperm of infertile men positive for C. trachomatis compared to uninfected men but without statistical significances (p = 0.62). Chlamydial infection was associated to loss of ΔΨm and caspase 3activation. Thus, C. trachomatis infection could be incriminated in apoptosis induction of spermatozoa. These effects may explain the negative direct impact of C. trachomatis infection on sperm fertilizing ability.

Abstract
This article provides an overview of infectious and inflammatory conditions associated with male infertility. These conditions may affect several components of the male reproductive tract and therefore have the ability to potentially alter sperm function. The effect of these conditions on male fertility is poorly understood and often underestimated.

Abstract
Chlamydia trachomatis (CT) is the most prevalent cause of sexually transmitted diseases. Although the prevalence of chlamydial infection is similar in men and women, current research and screening are still focused on women, who develop the most severe complications, leaving the study of male genital tract (MGT) infection underrated. Herein, we reviewed the literature on genital CT infection with special focus on the MGT. Data indicate that CT certainly infects different parts of the MGT such as the urethra, seminal vesicles, prostate, epididymis and testis. However, whether or not CT infection has detrimental effects on male fertility is still controversial. The most important features of CT infection are its chronic nature and the presence of a mild inflammation that remains subclinical in most individuals. Chlamydia antigens and pathogen recognition receptors (PRR), expressed on epithelial cells and immune cells from the MGT, have been studied in the last years. Toll-like receptor (TLR) expression has been observed in the testis, epididymis, prostate and vas deferens. It has been demonstrated that recognition of chlamydial antigens is associated with TLR2, TLR4, and possibly, other PRRs. CT recognition by PRRs induces a local production of cytokines/chemokines, which, in turn, provoke chronic inflammation that might evolve in the onset of an autoimmune process in genetically susceptible individuals. Understanding local immune response along the MGT, as well as the crosstalk between resident leukocytes, epithelial, and stromal cells, would be crucial in inducing a protective immunity, thus adding to the design of new therapeutic approaches to a Chlamydia vaccine.

Abstract
Infertility affects about 8% to 12% of couples, with male infertility being responsible for about 30% of cases. Sexually transmitted infections (STIs) are known to cause complications of pregnancy and are associated with tubal infertility in females, but the association with male fertility is still controversial. The prevalence of curable STIs has risen to an estimated 448 million a year with the number of people living with human immunodeficiency virus (HIV) at 34 million. This review looks at the evidence available to date, regarding the effect of STIs and male accessory gland infections on markers of male fertility and the evidence that STIs negatively affect sexual functioning, thus adversely affecting the ability to conceive. The review will also cover new developments in the use of medications and fertility treatments as an aid to conception in couples serodiscordant for HIV.

Abstract
In this prospective study, the fully automated cobas 4800 CT/NG and the cobas TaqMan CT tests were compared for Chlamydia trachomatis detection in urine and in genital specimens collected with Copan flocked swabs in culture media. A protocol was also established for the highly sensitive detection of C. trachomatis in semen specimens using the cobas 4800 CT/NG test. A total of 708 consecutive urogenital samples (293 male urine samples and 356 vaginal, 45 cervical and 14 urethral swabs) obtained from the Bacteriology Department, as well as 100 consecutive semen samples collected from patients attending the Reproduction Biology Department, Bordeaux University Hospital, France, from July to September 2010, were analysed. Positive and negative agreements between the cobas 4800 CT/NG and cobas TaqMan CT tests were 92.7 % [95 % confidence interval (CI), 82.7-97.1 %] and 99.2 % (95 % CI, 98.2-99.7 %), respectively, with an overall agreement of 98.7 % (699/708). The clinical sensitivity of the cobas 4800 CT/NG assay for C. trachomatis ranged from 90.9 to 100 % depending on specimen type, with an overall prevalence of 7.2 % (51/708). The clinical specificity ranged from 99.1 to 100 % depending on specimen type. Dilution of 25 µl semen samples in cobas PCR medium proved to be the most sensitive protocol with the lowest inhibition rate. In conclusion, the cobas 4800 CT/NG test was found to be an effective method for detection of C. trachomatis in semen, male urine and genital swab samples collected dry or in universal transport medium.

Abstract
OBJECTIVE In our study, we aimed to determine the prevalence of Chlamydia trachomatis, Mycoplasma hominis and Ureaplasma urealyticum infections among infertile couples and effects of these infections on infertility. MATERIALS AND METHODS Prevalence of Chlamydia, Mycoplasma, Ureaplasma antibodies and Chlamydia IgM antibodies and its effect on these agents' sperm parameters, namely, morphology, density, and motility were investigated among a total of 212 patients including fertile and infertile couples. Chlamydia, Mycoplasma, Ureaplasma antigens were evaluated using ELISA in the cervical and urethral samples. Chlamydia IgM antibody was measured using micro-ELISA in blood samples. RESULTS No difference was detected among the fertile and infertile groups in the serological investigation of urethral and cervical samples with respect to the prevalence of Chlamydia, Mycoplasma, Ureaplasma antigens and Chlamydia IgM antibody and sperm parameters (p > 0.05). DISCUSSION There is no significant difference between fertile and infertile couples in terms of the prevalence of the above mentioned infections. Accordingly, during the infertility assessment, infertile couples should not be routinely screened for these infective agents without any clinically sound evidence.

Abstract
To study the association between plasma antibodies to Chlamydia trachomatis and male infertility, 90 men from infertile couples attending a University Hospital IVF clinic for IVF/intracytoplasmic sperm injection, and 190 healthy blood donors as control subjects were studied for IgG and IgA antibodies to C. trachomatis, and for the men from infertile couples seminal fluid analysis was performed according to the World Health Organization criteria. The prevalence of plasma IgG antibodies to C. trachomatis was higher among men from infertile couples than control men, and men with chlamydial antibodies had lower sperm counts than those without.

Abstract
Genital infections with Chlamydia trachomatis occur in all social groups in Germany. About 100,000 German women are sterile because of tubal scarring due to chlamydiae. Genital chlamydial infections are asymptomatic in 70% of patients, even if salpingitis occurs. Typical symptoms of chlamydial infection are purulent cervicitis with vaginal discharge, painful cervical bleeding because of endometritis, lower abdominal pain with dyspareunia, and upper abdominal pain because of perihepatitis. DNA amplification tests on first voided urine or cervical swab are the most sensitive routine tests. Specific serum antibodies to C. trachomatis indicate a previous infection in sterile women. For treatment, a 10-14 day course of doxycycline 200 mg daily or a macrolide antibiotic in the patient as well as in the sexual partner is recommended. In the male, C. trachomatis causes urethritis and epididymitis. Opinions differ about involvement of the prostate gland and seminal vesicles. Identification of C. trachomatis antigen or DNA in the accessory gland secretions is not sufficiently reproducible. The two vectors are easily diagnosed in urethral swabs or in urine. The occurrence of chlamydial antibodies in serum or in seminal fluid is not a sign of current infection. Reliable studies which indicate a reduced fertility of men infected with C. trachomatis are not available.

Abstract
OBJECTIVE We assessed the risk of prostate cancer by exposure to Chlamydia trachomatis. METHOD Seven hundred thirty eight cases of prostate cancer and 2,271 matched controls were identified from three serum sample banks in Finland, Norway, and Sweden by linkage to the population based cancer registries. RESULTS A statistically significant inverse association (odds ratio, 0.69; 95% confidence interval, 0.51-0.94) was found. It was consistent by different serotypes and there was a consistent dose-response relationship. CONCLUSION C. trachomatis infection is not likely to increase the risk of prostate cancer. Whether the inverse relationship is true or due to difficulties in measuring the true exposure in prostatic tissue by serology, confounders or other sources of error remain open.

Abstract
The role of Chlamydia trachomatis in the cause of male infertility is under discussion. This paper attempts to summarize data from the literature, which support the role of C. trachomatis in male infertility or oppose this suggestion. The following observations are based on a survey of the literature: 1) Chlamydia trachomatis is a frequent pathogen in male genital inflammation, the micro-organisms are rarely present in healthy men. 2) Without doubt, C. trachomatis causes inflammations of the male urethra and the epididymis. Prostatitis and glandulitis vesicalis are discussed controversially. 3) Chlamydia trachomatis antigen or DNA is not demonstrable in secretions of the male accessory glands including the semen with sufficient reproducibility. However, it is easily demonstrable in urethral swabs and the urine. 4) Determination of chlamydial antibodies in serum or semen does not conclusively indicate a current infection with C. trachomatis. 5) There are no conclusive studies showing that men infected with C. trachomatis are less fertile than uninfected men. 6) The male genital chlamydial infection is a threat to the female genital organs, because C. trachomatis infection of the female genital organs may be deleterious to female fertility.

Abstract
Elastase is a protease released by polymorphonuclear neutrophils (PMN) during the inflammatory process. Since 1987, seminal elastase-inhibitor complex (Ela/alpha1-PI) has been proposed as a marker of male silent genital tract inflammation. Measured by immunoassay in seminal plasma, Ela/alpha1-PI at a cut-off level of > or = 230 microg/l, is useful in the detection of genital tract inflammation. The prevalence of increased seminal Ela/alpha1-PI in infertile men is significantly higher than that observed in fertile men. The Ela/alpha1-PI level is positively correlated with other seminal fluid markers of male genital tract inflammation: reduced semen volume, citric acid, fructose, and increased albumin, complement component C3, caeruloplasmin, immunoglobulins IgG and IgA, and cytokines interleukins-8 and -6. A higher seminal Ela/alpha1-PI level is significantly associated with tubal damage in female partners. After antibiotic therapy, a decrease of Ela/alpha1-PI level is observed. The presence of tubal damage in the partner may negatively affect the response to antibiotic treatment. A higher seminal Ela/alpha1-PI is associated with lower percentage of sperm with single-stranded deoxyribonucleic acid (DNA) and better fertilization rate in in vitro fertilization. Besides infertility, the determination of Ela/alpha1-PI is useful to confirm the presence of prostate and other male accessory gland bacterial inflammation. Screening for PMN Ela/alpha1-PI is easy to perform and reproducible and is a reliable quantitative test for diagnosis and prognosis of silent genital tract inflammation of couples. Moreover, sequential determinations allow the follow-up of inflammation during and after therapy.
