Chlamydia trachomatis, Neisseria gonorrhoea, and Trichomonas vaginalis infections among pregnant women and male partners in Dutch midwifery practices: prevalence, risk factors, and perinatal outcomes.

BACKGROUND: Antenatal screening for HIV, syphilis and HBV has been successfully implemented in The Netherlands, but data on other STI among pregnant women or male partners are limited. Our objectives: (i) to assess the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) among pregnant women and male partners, (ii) to identify risk factors for these STI during pregnancy, and (iii) to identify adverse perinatal outcomes (APO) associated with STI. METHODS: Cross-sectional study. Pregnant women aged ≤ 30 years (n = 548) and male partners (n = 425) were included at 30 midwifery practices during 2012-2016. Participants provided a self-collected vaginal swab (women) or urine sample (men) and completed a questionnaire. Perinatal data were derived from pregnancy cards. APO was defined as premature rupture of membranes, preterm delivery, low birthweight, stillbirth, neonatal conjunctival and respiratory infections. Data were analysed by logistic regression. RESULTS: STI were present in 2.4% of pregnant women (CT 1.8%, NG 0.4%, TV 0.4%), and in 2.2% of male partners (CT 2.2%, NG 0.2%, TV 0%). Of young women (≤ 20 years), 12.5% had a CT infection. Prevalent STI during pregnancy was associated with female young age (≤ 20 years vs ≥ 21 years) (adjusted OR 6.52, CI 95%: 1.11-38.33), male non-Western vs Western background (aOR 9.34, CI 2.34-37.21), and female with ≥ 2 sex partners < 12 months vs 0-1 (aOR 9.88, CI 2.08-46.91). APO was not associated with STI, but was associated with female low education (aOR 3.36, CI 1.12-10.09), complications with previous newborn (aOR 10.49, CI 3.21-34.25 vs no complications) and short duration (0-4 years) of relationship (aOR 2.75, CI 1.41-5.39 vs ≥ 5 years). Small-for-gestational-age was not associated with STI, but was associated with female low education (aOR 7.81, 2.01-30.27), female non-Western background (aOR 4.41, 1.74-11.17), and both parents smoking during pregnancy (aOR 2.94, 1.01-8.84 vs both non-smoking). CONCLUSIONS: Prevalence of STI was low among pregnant women and male partners in midwifery practices, except for CT among young women. The study could not confirm previously observed associations between STI and APO, which is probably due to low prevalence of STI, small study sample, and presumed treatment for STI.

Evaluation of a health system-wide pharmacist-driven emergency department laboratory follow-up and antimicrobial management program.

BACKGROUND: Emergency Department (ED) follow-up programs ensure that cultures, laboratory studies, and empiric antimicrobials are appropriately managed post-discharge. We sought to provide a comprehensive assessment of a pharmacist-driven laboratory follow-up process in a large, integrated health system. METHODS: A retrospective, observational review of 13 EDs was conducted. Patients were included if they had a laboratory study sent from the ED between December 1, 2017 and May 31, 2018 that did not result while the patient was in the ED. Microbiology results analyzed were urine, wound, respiratory, stool, throat, bacterial vaginosis, vaginal candidiasis, and sexually transmitted infections (STI). Examples of laboratory results assessed were metabolic panels and drug levels. The primary objective was to quantify the number of interventions made by pharmacists. RESULTS: During a 6-month period, pharmacists reviewed 9107 microbiology results and 6211 laboratory results. The majority of results were urine cultures (3998, 50.6%) followed by STI results (1198, 15.2%). Of 7663 encounters, 39.8% required interventions and/or follow-up with a total of 3049 interventions made and 3333 patients educated. The most common interventions were initiation of therapy (1629, 53.4%), change in medication (505, 16.6%), and follow-up with a clinician (322, 10.6%). Pharmacists reviewed microbiology results and completed interventions in a median of 25.3 h from the time the result was received in the electronic health record. CONCLUSION: Almost 40% of ED encounters required an intervention after discharge. A pharmacist led laboratory follow-up program is an important adjunct to facilitating stewardship and culture management in the ED.

Host-Pathogen Interactions during Female Genital Tract Infections.

Dysbiosis in the female genital tract (FGT) is characterized by the overgrowth of pathogenic bacterial, fungal, or protozoan members of the microbiota, leading to symptomatic or asymptomatic infections. In this review, we discuss recent advances in studies dealing with molecular mechanisms of pathogenicity factors of Gardnerella vaginalis, Mycoplasma genitalium, Mycoplasma hominis, Neisseria gonorrhoeae, Streptococcus agalactiae, Chlamydia trachomatis, Trichomonas vaginalis, and Candida spp., as well as their interactions with the host and microbiota in the various niches of the FGT. Taking a holistic approach to identifying fundamental commonalities and differences during these infections could help us to better understand reproductive tract health and improve current prevention and treatment strategies.

Understanding the burden of bacterial sexually transmitted infections and Trichomonas vaginalis among black Caribbeans in the United Kingdom: Findings from a systematic review.

BACKGROUND: In the UK, people of black Caribbean (BC) ethnicity continue to be disproportionately affected by bacterial sexually transmitted infections (STIs) and Trichomonas vaginalis (TV). We systematically reviewed evidence on the association between bacterial STIs/TV and ethnicity (BC compared to white/white British (WB)) accounting for other risk factors; and differences between these two ethnic groups in the prevalence of risk factors associated with these STIs, sexual healthcare seeking behaviours, and contextual factors influencing STI risk. METHODS: Studies presenting relevant evidence for participants aged ≥14 years and living in the UK were eligible for inclusion. A pre-defined search strategy informed by the inclusion criteria was developed. Eleven electronic databases were searched from the start date to September-October 2016. Two researchers independently screened articles, extracted data using a standardised proforma and resolved discrepancies in discussion with a third researcher. Descriptive summaries of evidence are presented. Meta-analyses were not conducted due to variation in study designs. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. RESULTS: Of 3815 abstracts identified, 15 articles reporting quantitative data were eligible and included in the review. No qualitative studies examining contextual drivers of STI risk among people of BC ethnicity were identified. Compared to the white/WB ethnic group, the greater STI/TV risk among BCs was partially explained by variations in socio-demographic factors, sexual behaviours, and recreational drug use. The prevalence of reporting early sexual debut (<16 years), concurrency, and multiple partners was higher among BC men compared to white/WB men; however, no such differences were observed for women. People of BC ethnicity were more likely to access sexual health services than those of white/WB ethnicity. CONCLUSIONS: Further research is needed to explore other drivers of the sustained higher STI/TV prevalence among people of BC ethnicity. Developing holistic, tailored interventions that address STI risk and target people of BC ethnicity, especially men, could enhance STI prevention.

Clinical diagnostic and therapeutic aspects of 221 consecutive anorectal Chlamydia trachomatis and Neisseria gonorrhoeae sexually transmitted infections among men who have sex with men.

OBJECTIVES: Proctitis caused by Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are known as sexually transmitted infections (STI). This study describes their clinical, diagnostic and therapeutic aspects. METHODS: Between 01/2013-03/2015, all MSM consulting for proctitis at proctology Institute-Saint-Joseph's Hospital, Paris, were included. Demographic, past-medical history, STI status and medical treatment were collected. Detection of CT/NG was performed by Transcription-Mediated Amplification (TMA) and antimicrobial susceptibilities for Ng by agar diffusion method. RESULTS: On 441 rectal samples collected, 221 (50.1%) were positive: 109 Ct (49.3%), 70 Ng (31.7%), 42 positive for both etiologies (19%). Among Ng infections, no resistance was detected to azithromycin and ceftriaxone. However, 84 strains (43.2%) were resistant to fluoroquinolones. More than one episode was diagnosed for 10 (5.1%) and 12 (6.2%) patients with CT and NG infections respectively. Anal abscesses were found for 27 (13.9%) patients, and 14 (7.2%) of them underwent surgery for anal fistula. CONCLUSIONS: The prevalence of CT/NG anorectal infections described is high on symptomatic patients, and a significant level of abscess was reported. These results confirm the interest of the association of recommended antibiotics excluding quinolones. Prospective studies would be relevant on complicated forms of anorectal infections.

Epididymo-orchitis caused by enteric organisms in men > 35 years old: beyond fluoroquinolones.

Epididymo-orchitis is a common urological condition in men of all ages, causing a unilateral or bilateral swelling of the epididymis and/or testis. It is frequently caused by sexually transmitted infections, Chlamydia trachomatis and Neisseria gonorrheae, as well as common enteric organisms implicated in urinary tract infections. Men over 35 years old may develop epididymo-orchitis associated with enteric organisms, often associated with functional bladder outlet problems such as benign prostatic hyperplasia or urethral stricture disease. Fluoroquinolones, especially ciprofloxacin, have long been the mainstay of treatment for these infections; however, rising resistance to ciprofloxacin in E. coli isolates in Europe and the USA means that there is an unprecedented necessity for alternative antimicrobials with adequate penetration into genital tissues (epididymis and testes) to allow appropriate and comprehensive treatment of epididymo-orchitis in this group of patients.

Proteflazid® and local immunity in diseases caused by human papillomavirus, herpesvirus and mixed urogenital infections.

Reporting of clinical trials results for Proteflazid® in the drug formulation suppositories and vaginal swabs soaked in the solution of the drug to the local immunity of the female reproductive tract. AIM: The aim of study was to examine the state of local immunity in the reproductive tract of women with sexually transmitted diseases caused by human papillomavirus, herpes viruses (Type 1, 2) and mixed infection (herpes viruses + chlamydia). MATERIALS AND METHODS: The trials involved 216 women with viral sexually transmitted diseases: Cervical Dysplasia associated with papillomavirus infection (HPV) (Group 1); Herpes genitalis type 1 (HSV- 1) and type 2 (HSV-1) (Group 2); mixed infection - HSV-1, HSV-2 and chlamydia (Group 3). RESULTS: Treatment results have confirmed that Proteflazid® contributes to sustainable performance improvement of basic factors of local immunity - sIgA, lysozyme and complement component C3 in the cervical mucus for all three groups of women. CONCLUSIONS: Proteflazid® enhances level of local immunity markers (sIgA, lysozyme, C3 complement component) and improves their ratios. Also it intensifies anticontagious activity of mucosal protection and female reproductive system as whole, during treatment diseases caused by human papillomavirus, herpesvirus and mixed urogenital infections (herpesvirus and chlamydia).

Knowledge and acceptability of Chlamydia trachomatis screening among pregnant women and their partners; a cross-sectional study.

BACKGROUND: Chlamydia trachomatis infections in pregnancy can cause maternal disease, adverse pregnancy outcomes and neonatal disease, which is why chlamydia screening during pregnancy has been advocated. The effectiveness of a screening program depends on the knowledge of health care professionals, women and partners and the acceptability for screening of the target population. We assessed the knowledge of chlamydia infection among pregnant women and their partners in the Netherlands, their attitudes towards testing, and their experiences of being offered a chlamydia test. In addition, we evaluated the association between participants' background characteristics and knowledge of chlamydia. METHODS: Pregnant women aged ≤ 30 years and their partners (regardless of their age) attending one of the participating primary midwifery care practices in the Netherlands were invited to participate. All participants completed a questionnaire, pregnant women provided a vaginal swab and partners provided a urine sample to test for C. trachomatis. RESULTS: In total, 383 pregnant women and 282 partners participated in the study of whom 1.9% women and 2.6% partners tested chlamydia positive. Participants had high levels of awareness (92.8%) of chlamydial infection. They were knowledgeable about the risk of chlamydia infection; median knowledge score was 9.0 out of 12.0. Lower knowledge scores were found among partners (p-value <0.001), younger aged (p-value 0.02), non-western origin (p-value <0.001), low educational level (p-value <0.001), and no history of sexually transmitted infections (p-value <0.001). In total, 78% of respondents indicated that when pregnant women are tested for chlamydia, their partners should also be tested; 54% believed that all women should routinely be tested. Pregnant women more often indicated than partners that testing partners for chlamydial infection was not necessary (p-value <0.001). The majority of pregnant women (56.2%) and partners (59.2%) felt satisfied by being offered the test during antenatal care. CONCLUSION: Pregnant women and their partners were knowledgeable about chlamydial infection, found testing, both pregnant women and their partners, for chlamydia acceptable and not stigmatizing.

Sexually transmitted diseases putative drug target database: a comprehensive database of putative drug targets of pathogens identified by comparative genomics.

OBJECTIVE: Sexually transmitted diseases (STD) are the serious public health problems and also impose a financial burden on the economy. Sexually transmitted infections are cured with single or multiple antibiotics. However, in many cases the organism showed persistence even after treatment. In the current study, the set of druggable targets in STD pathogens have been identified by comparative genomics. MATERIALS AND METHODS: The subtractive genomics scheme exploits the properties of non-homology, essentiality, membrane localization and metabolic pathway uniqueness in identifying the drug targets. To achieve the effective use of data and to understand properties of drug target under single canopy, an integrated knowledge database of drug targets in STD bacteria was created. Data for each drug targets include biochemical pathway, function, cellular localization, essentiality score and structural details. RESULTS: The proteome of STD pathogens yielded 44 membrane associated proteins possessing unique metabolic pathways when subjected to the algorithm. The database can be accessed at http://biomedresearchasia.org/index.html. CONCLUSION: Diverse data merged in the common framework of this database is expected to be valuable not only for basic studies in clinical bioinformatics, but also for basic studies in immunological, biotechnological and clinical fields.

Plants traditionally used individually and in combination to treat sexually transmitted infections in northern Maputaland, South Africa: antimicrobial activity and cytotoxicity.

ETHNOPHARMACOLOGICAL RELEVANCE: Although medicinal plants are used extensively to treat sexually transmitted infections (STIs) in rural northern Maputaland, KwaZulu-Natal, the efficacy and safety of these plants have not previously been evaluated. AIM OF STUDY: A study was designed to investigate the in vitro antimicrobial activity and cytotoxicity profiles of a selection (individual plants and selected combinations) of traditionally used plants in this study area. MATERIALS AND METHODS: Aqueous and organic (dichloromethane: methanol, 1:1) extracts were prepared. Antimicrobial activity was assessed using the minimum inhibitory concentration (MIC) assay against the STI associated pathogens; Candida albicans ATCC 10231, Ureaplasma urealyticum clinical strain, Oligella ureolytica ATCC 43534, Trichomonas vaginalis clinical strain, Gardnerella vaginalis ATCC 14018 and Neisseria gonorrhoeae ATCC 19424. For the combination study, interactions were assessed using the fractional inhibitory concentration (ΣFIC). The plant species were assessed for safety using the 3-[4,5-dimethyl-2-thiazol-yl]-2,5-diphenyl-2H-tetrazolium bromide (MTT) cellular viability assay on the human embryonic kidney epithelial (Graham, HEK-293) cell line. RESULTS: For the antimicrobial studies, U. urealyticum was the most sensitive of the six test organisms, with the aqueous extract of Ranunculus multifidus (0.02mg/ml) and the organic extract of Peltophorum africanum (0.04mg/ml) being the most antimicrobially active plant species studied. Sclerocarya birrea was found to have the broadest spectrum of activity (mean MIC of 0.89mg/ml). The only plant species to exhibit some degree of cytotoxicity against the kidney epithelial cell line was Kigelia africana (100µg/ml), with 22% and 16% cell death for the aqueous and organic extracts, respectively. Of the 13 combinations studied, several synergistic combinations were evident, the most prominent being the combination of Albizia adianthifolia and Trichilia dregeana (aqueous extract) with an ΣFIC value of 0.15 against O. ureolytica. Synergistic interactions were observed regardless of the ratio of the aqueous mixtures of the two plants. Syzygium cordatum and S. birrea (aqueous extract) was also a combination of interest, demonstrating synergistic (ΣFIC=0.42) interactions against O. ureolytica. This combination, however, also displayed some cytotoxicity towards the human epithelial cell line. CONCLUSION: This study demonstrated that anecdotal evidence of plant use does not always correlate with in vitro activity. Furthermore, the toxicological profiling is of utmost importance as if not combined in its correct ratio can lead to potential adverse effects.

Pigtailed macaque model refinement: topical microbicide safety in the presence of coitus.

BACKGROUND: Inclusion of sexual activity in the macaque model for topical microbicide safety evaluation would more closely mimic human use of topical microbicides and provide a more rigorous safety assessment. METHODS: Initially, male-female partners were monitored in cohousing arrangements to determine whether macaques would copulate ad libitum. The logistics of performing vaginal examinations before and after coital visits were analyzed and optimized. Findings from cervicovaginal examinations conducted before and after sexual activity were compared. RESULTS: Coital activity was reliably observed in the majority of cohousing sessions, representing all phases of the menstrual cycle. Female macaques were trained to be restrained while fully alert for pre-coital vaginal sampling. Post-coital examinations occur under general sedation. Post-coital examinations reveal alterations to tissues, microbiology, and pH compared with pre-coital visits. CONCLUSIONS: This work clearly demonstrates that it is feasible to incorporate sexual activity in the macaque model for topical microbicide safety assessment.

An antimicrobial investigation of plants used traditionally in southern Africa to treat sexually transmitted infections.

AIM OF THE STUDY: Eighteen plants were assessed for antimicrobial activity against pathogens associated with prevalent urogenital/sexually transmitted infections. Plant selection was based on information obtained from the ethnobotanical literature. MATERIALS AND METHODS: Dried plant material was submerged in a 1:1 mixture of methanol and dichloromethane for 24 h. Aqueous extracts were prepared by submerging dried plant material in sterile distilled water for 24 h followed by lyophilization. Essential oils were distilled from the two aromatic plant species (Tarchonanthus camphoratus and Croton gratissimus). Antimicrobial activity was assessed using the micro-well minimum inhibitory concentration (MIC) assay with specific modifications to facilitate fastidious growth of pathogens. RESULTS: Tarchonanthus camphoratus (solvent extract) showed the most significant broad spectrum activity with MIC values ranging between 0.50 and 0.70 mg/ml against five of the six pathogens tested. Other noteworthy activity was found for Hypericum aethiopicum (root) at 0.3 mg/ml (Neisseria gonorrhoeae).Polygala fruticosa and the solvent root extract of Hypericum aethiopicum showed highest sensitivities towards Gardnerella vaginalis at 0.2 mg/ml. Efficacy of the solvent extracts against the pathogen Oligella ureolytica demonstrated antimicrobial activity (MIC values

[Prophylaxis of recurrences of urinary tract infection].

Canephron N, a medicine of plant origin, was tested in outpatient aftertreatment for prophylaxis of recurrent infection of the upper urinary tract, in intravesical therapy for prophylaxis of lower urinary tract infections in sexually transmitted diseases. Canephron N provides an additional anti-inflammatory and symptomatic effect which lasts after active antibacterial therapy, and effective antibacterial protection in invasive manipulations, intravesical instillations, in particular. The drug showed good tolerance.

Mycoplasma genitalium in men who have sex with men at male-only saunas.

OBJECTIVES: To determine the prevalence and clinical associations of Mycoplasma genitalium in urethral, rectal and pharyngeal specimens collected from men who have sex with men (MSM) attending male-only saunas. METHODS: A cross-sectional study of 521 MSM attending six male-only saunas in Melbourne was conducted between October 2001 and September 2002. Stored urine and rectal and pharyngeal swabs were tested for M genitalium by real-time polymerase chain reaction. The prevalence of M genitalium and clinical associations were determined. RESULTS: A high prevalence (12.9%; 95% CI 10.2% to 15.9%) of sexually transmitted infections (STIs) was found in MSM. M genitalium (2.1%; 95% CI 1.1% to 3.6%) was less common than Chlamydia trachomatis (8.1%; 95% CI 5.9% to 10.6%, p<0.001), and Neisseria gonorrhoeae (4.8%; 95% CI 3.2% to 6.9%, p = 0.02). M genitalium was most likely to be detected as an asymptomatic rectal (1.6%; 95% CI 0.8% to 3.0%) or urethral infection (0.6%; 95% CI 0.2% to 1.6%, p = 0.12), but was absent from the pharynx. In comparison, C trachomatis was more common in the rectum (6.2%; 95% CI 4.3% to 8.6%) than urethra (1.8%; 95% CI 0.9% to 3.2%, p = 0.004), and was uncommon in the pharynx (0.6%; 95% CI 0.1% to 1.6%). Urethral infection with N gonorrhoeae (0.2%; 95% CI 0.01% to 1.0%) was rare, but it was as common in the pharynx (2.5%; 95% CI 1.4% to 4.2%) as the rectum (2.2%; 95% CI 1.2% to 3.8%). No significant demographic or behavioural associations with M genitalium were identified. CONCLUSION: M genitalium was less common than C trachomatis and N gonorrhoeae in MSM attending male-only saunas and was most often detected as an asymptomatic rectal or a urethral infection but was absent from the pharynx. To inform STI screening strategies in MSM, more data are needed to understand how common M genitalium infection is in urethral and non-urethral sites in MSM, and how it contributes to clinical symptoms.

Panorama actual de la epidemiología, diagnóstico y tratamiento de las infecciones de transmisión sexual / Update on the epidemiology, diagnosis and treatment of sexually-transmitted infections

En la última década se ha constatado un aumentoprogresivo de los casos de infecciones de transmisiónsexual en el territorio europeo. Las causas de esteaumento no están claras, pero parece influido por cambiosen las conductas sociales, los fenómenos migratorios y los viajes internacionales, junto con la aparición de grupos de riesgo no suficientemente valorados hasta ahora. La utilización habitual de técnicas de diagnóstico molecular para muchas de estas infecciones ha resuelto muchos problemas de sensibilidad e idoneidad de las muestras para el diagnóstico microbiológico, pudiéndose emplear muestras no invasivas, y ha contribuido, sin duda, a este aumento de casos. Por otro lado, los métodos moleculares también se van implantando en el estudio de la sensibilidad a los antibióticos y antivirales, así como para la caracterización molecular de los aislados. Todo lo anterior, junto a la aprobación de la vacuna frente al virus del papiloma humano, ha cambiado el panorama de las infecciones de transmisión sexual en el territorio europeo

In the last decade, cases of sexually-transmitted infections (STIs) have progressively increased in Europe. The reasons for this increase are unclear, but may involve changes in social behavior, migration and international travel, coupled with the emergence of risk groups that have not been taken into sufficient consideration to date.The routine use of molecular diagnostic techniques formany of these infections has solved many problems ofsensitivity and the suitability of samples formicrobiological diagnosis: non-invasive samples can beused, which has undoubtedly contributed to the increasein the number of cases. Moreover, molecular methodshave also been introduced for antibiotic and antiviralsusceptibility testing, as well as for molecularcharacterization of clinical isolates. All of these factors, together with the approval of the vaccine against the human papillomavirus, have changed the landscape of STIs across Europe

Neisseria gonorrhoeae in a London sexually transmitted infection clinic not fully sensitive to quinolones: are isolates imported and how effective is ciprofloxacin as a first-line therapy?

Our objectives were to determine the prevalence of Neisseria gonorrhoeae not fully sensitive to ciprofloxacin from a sexually transmitted infection (STI) clinic in London and where the isolates were acquired from. Data of antibiotic sensitivities of N. gonorrhoeae from 292 patients were reviewed over a 6-month period at St Mary's Genitourinary Medicine (GUM) Clinic, London. Isolates which exhibited reduced susceptibility (minimum inhibitory concentration [MIC] 0.03-0.12 mg/l) and high level resistance (MIC>0.12 mg/l) to ciprofloxacin represented 10% and 1.3% of the total respectively. All patients infected with a high level resistant isolate to ciprofloxacin had had a recent sexual partner from abroad but 18 of the 28 patients infected with a reduced susceptibility isolate denied recent travel. None of the 20 patients with a non-sensitive isolate who re-attended for post treatment cultures had persistant gonococcal infection. From this study we concluded that although N. gonorrhoeae resistant to ciprofloxacin was rare and probably always acquired abroad, isolates exhibiting reduced susceptibility were more common and were mainly as a result of infection from the UK. A stat dose of ciprofloxacin 500 mg and doxycycline 100 mg twice a day for one week was effective treatment.
