Abstract
Relevant studies increasingly indicate that female reproductive health is confronted with substantial challenges. Emerging research has revealed that the microbiome interacts with the anatomy, histology, and immunity of the female reproductive tract, which are the cornerstone of maintaining female reproductive health and preventing adverse pregnancy outcomes. Currently, the precise mechanisms underlying their interaction and impact on physiological functions of the reproductive tract remain elusive, constituting a prominent area of investigation within the field of female reproductive tract microecology. From this new perspective, we explore the mechanisms of interactions between the microbiome and the anatomy, histology, and immunity of the female reproductive tract, factors that affect the composition of the microbiome in the female reproductive tract, as well as personalized medicine approaches in managing female reproductive tract health based on the microbiome. This study highlights the pivotal role of the female reproductive tract microbiome in maintaining reproductive health and influencing the occurrence of reproductive tract diseases. These findings support the exploration of innovative approaches for the prevention, monitoring and treatment of female reproductive tract diseases based on the microbiome.

Abstract
Genital herpes (GH) is a sexually transmitted infection causing recurrent, self-limited genital, buttock, and thigh ulcerations. Symptoms range from unrecognized or mild to severe with frequent recurrences. Herpes simplex viruses (HSV) type-1 or type-2 cause GH. HSV establishes latency in sacral ganglia and causes lifelong infection. Viral reactivation leads to genital ulceration or asymptomatic shedding which may lead to transmission. HSV infection during pregnancy can cause fulminant hepatitis and neonatal transmission. Severe and atypical manifestations are seen in immunocompromised people. Guanosine analogs treat symptoms and prevent recurrences, shedding, and transmission. Novel preventive and therapeutic strategies are in development.

Abstract
Sexually transmitted infections (STIs) are caused by various pathogens, many of which have common symptoms. Diagnostic tests are critical to supporting clinical evaluations in making patient management decisions. Molecular diagnostics are the preferred test type when available, especially in asymptomatic patients for many STIs. However, for some infections, serology offers the best insight into infectious status. Clinicians should be aware of the performance characteristics of the available STI diagnostic tests and understand how to use them. Point-of-care tests are helpful to implement rapid and accurate treatment responses, which are particularly helpful in certain at-risk populations.

Abstract
Vaginal symptoms are one of the most common reasons women consult with physicians and can significantly impact quality of life. The differential diagnosis of vaginal discharge includes physiologic discharge, vaginitis, cervicitis, and pelvic inflammatory disease (PID). Vaginitis is inflammation of the vagina, most commonly caused by bacterial vaginosis (BV), vulvovaginal candidiasis, and trichomoniasis infections. Cervicitis is an inflammation of the cervix and typically caused by Chlamydia trachomatis and Neisseria gonorrhoeae. PID is infection of the female upper genital tract, involving the uterus, fallopian tubes, ovaries, and/or pelvic peritoneum and usually caused by Chlamydia trachomatis, Neisseria gonorrhoeae, and bacterial vaginosis-associated pathogens. A pelvic exam should be performed for any woman presenting with vaginal discharge to confirm the diagnosis and rule out an upper tract infection. BV and vulvovaginal candidal infections only require treatment if symptomatic and do not require partner therapy, whereas treatment and partner therapy is recommended for sexually transmitted illnesses, such as trichomoniasis, chlamydia and gonorrhea. Vaginitis may be uncomfortable, but rarely leads to serious long-term consequence, but pelvic inflammatory disease can lead to serious long-term sequelae, including increased risk for ectopic pregnancy, infertility, and chronic pelvic pain.

Qualitative and Quantitative Detection of Multiple Sexually Transmitted Infection Pathogens Reveals Distinct Associations with Cervicitis and Vaginitis. Microbiol Spectr 2022; 10:e0196622. [PMID: 36314938 PMCID: PMC9769840 DOI: 10.1128/spectrum.01966-22] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 10/05/2022] [Indexed: 11/07/2022] Open
Abstract
Many diverse pathogens have been discovered from reproductive-tract infections, but the relationship between the presence and abundance of particular pathogen species and disease manifestations is poorly defined. The present work examined the association of multiple common pathogens causing sexually transmitted infections (STIs) with cervicitis and vaginitis. The presence and abundance of 15 STI pathogens and the genotypes of human papillomavirus were determined in a cohort of 944 women that included 159 cervicitis patients, 207 vaginitis patients, and 578 healthy controls. Logistic regression and random forest models were constructed and validated in a separate cohort of 420 women comprising 52 cervicitis patients, 109 vaginitis patients, and 259 healthy controls. The frequency of individual STI pathogen species varied among the symptomatic patients and healthy controls. Abundance determination was necessary for most pathogens that were associated with the studied diseases. STI pathogens were more commonly associated with cervicitis than with vaginitis. Pathogen identification- and quantification-based diagnosis was observed for cervicitis with high sensitivity and specificity, but for vaginitis, the assay results would need to be combined with results of other diagnostic tests to firmly establish the pathogen-disease correlation. Integrated qualitative and quantitative detection of a selected panel of common STI pathogens can reveal their association with cervicitis and vaginitis. STI pathogen identification and quantification can be used to diagnose cervicitis and also help improve correct diagnosis of vaginitis. IMPORTANCE Scarce information exists with regard to whether STI pathogens can be defined as valid microbiological predictive markers for the diagnosis of cervicitis and vaginitis. We therefore conducted this study to assess the presence and abundance of a wide range of STI pathogens among patients having these two diseases and healthy controls as well. High sensitivity and specificity were observed for cervicitis by pathogen identification- and quantification-based diagnosis. In contrast, the assay results obtained for vaginitis would need to be combined with test results obtained by other diagnostic methods to decisively establish the pathogen-disease correlation. Simultaneous qualitative and quantitative detection of a selected panel of common STI pathogens and further coupling with machine learning models is worthwhile for establishing pathogen-based diagnosis of gynecological inflammations, which could be of great value in guiding the rational use of antimicrobials to control the spread of STIs.

Abstract
Approximately 40% of cases of spontaneous preterm birth (sPTB) are associated with ascending intrauterine infections. The cervix serves as a physical and immunological gatekeeper, preventing the ascent of microorganisms from the vagina to the amniotic cavity. The cervix undergoes remodeling during pregnancy. It remains firm and closed from the start until the late third trimester of pregnancy and then dilates and effaces to accommodate the passage of the fetus during delivery. Remodeling proceeds appropriately and timely to maintain the pregnancy until term delivery. However, risk factors, such as acute and chronic infection and local inflammation in the cervix, may compromise cervical integrity and result in premature remodeling, predisposing to sPTB. Previous clinical studies have established bacterial (i.e., chlamydia, gonorrhea, mycoplasma, etc.) and viral infections (i.e., herpesviruses and human papillomaviruses) as risk factors of PTB. However, the exact mechanism leading to PTB is still unknown. This review focuses on: (1) the epidemiology of cervical infections in pregnant patients; (2) cellular mechanisms that may explain the association of cervical infections to premature cervical ripening and PTB; (3) endogenous defense mechanisms of the cervix that protect the uterine cavity from infection and inflammation; and (4) potential inflammatory biomarkers associated with cervical infection that can serve as prognostic markers for premature cervical ripening and PTB. This review will provide mechanistic insights on cervical functions to assist in managing cervical infections during pregnancy.

Abstract
OBJECTIVE The aim: To obtain the first estimates of the current prevalence of healthcare-associated cervicitis (HACs) and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS Materials and methods: We conducted a retrospective multicentre cohort study was based on surveillance data from January 1st, 2019 to December 31st, 2021 in Ukraine. Antibiotic susceptibility testing was determined by Kirby-Bauer disc diffusion test according to the protocol of the European Committee on Antimicrobial Susceptibility Testing. RESULTS Results: Of the 6,885 participants in this study, 1746 women (25.5%) met the clinical definition of cervicitis. Prevalence of HACs and cervcits caused sexually transmitted pathogens were 12.7% and 8.3%, respectively. The incidence of HACs among women with a history of gynecological procedures was 25.4%. The main causes of HACs were legal induced abortions (28.8%), vaginal hysterectomy (23.9%), and postpartum instrumental examination (12.8%). The predominant pathogens of HACs were: Escherichia coli, Enterobacter spp., Klebsiella spp., Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis. Methicillin-resistance was observed in 20.8% of S. aureus (MRSA). Vancomycin resistance was observed in 7.4% of isolated enterococci (VRE). Resistance to third-generation cephalosporins was observed in 13.1% Klebsiella spp. and E.coli 17.5% isolates. Carbapenem resistance was identified in 11.6% of P.aeruginosa isolates. The prevalence of ESBL production among E. coli isolates was significantly higher than in K. pneumoniae (33.5%, vs 8.7%). The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 34.6%. CONCLUSION Conclusions: This study showed that the prevalence of healthcare-associated cervicitis in Ukraine is high, and many cases were caused by antibiotic-resistant pathogens.

Genital Chlamydia trachomatis Seroprevalence and Uterine Fibroid Development: Cohort Study of Young African-American Women. Microorganisms 2021; 10:microorganisms10010010.

Abstract
Few studies have investigated the 1930s hypothesis that reproductive tract infections are risk factors for fibroid development. In our 2017 cross-sectional analysis from the Study of Environment, Lifestyle, and Fibroids (2010–2018), a large Detroit community-based cohort of 23–35 year-old African-American women with ultrasound fibroid screening, we found an inverse association between seropositivity for genital Chlamydia trachomatis (gCT) infection and fibroids. With prospective data from the cohort (standardized ultrasounds every 20 months over 5 years), we examined gCT’s associations with fibroid incidence (among 1158 women fibroid-free at baseline) and growth. We computed adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for incidence by gCT serostatus using Cox proportional hazards models. GCT’s influence on growth was assessed by estimating the difference between fibroid size change for seropositive vs. seronegative between successive ultrasounds (1254 growth measures) using a linear mixed model. Growth was scaled to change over 18 months. GCT seropositivity was not associated with fibroid incidence (aHR, 1.0 95% CI: 0.79, 1.29) or growth (4.4%, 95% CI: −5.02, 14.64). The current evidence based on both biomarker gCT data, which can capture the common undiagnosed infections, and prospective ultrasound data for fibroids suggests that Chlamydia is unlikely to increase fibroid risk.

Abstract
Luohuazizhu suppository is a Traditional Chinese Medicine used in clinic to treat cervicitis, which is prepared from Callicarpa nudiflora Hook. et Arn (C. nudiflora), an herbal Chinese medicine named Luohuazizhu. This study aimed to figure out the active constituents of C. nudiflora and the potential mechanism for its anti-cervicitis effect. The ethanol extract in C. nudiflora (CNE) and the different fractions of CNE extracted by petroleum ether (CNE-p), dichloromethane (CNE-d), and n-butanol (CNE-b) were tested in vivo for their anti-cervicitis effects. Then the isolated compounds from the CNE-p were tested in vitro for their anti-inflammatory activities. The results displayed that CNE-p, CNE-d, and CNE-b exhibited adequate anti-cervicitis effects, with CNE-p showing the highest efficacy. Further experiment demonstrated that CNE-p could significantly inhibit the expression of NLRP3 in vitro. Six diterpenoids obtained from the CNE-p showed the ability to regulate inflammatory factor levels in vitro. Among these compounds, compounds 1 (callicarpic acid A) and 2 (syn-3,4-seco-12S-hydroxy-15,16-epoxy-4(18),8(17),3(16),14(15)-labdatetraen-3-oic acid) were the most effective agents, and they also inhibited the expression level of NLRP3 in vitro. The results confirmed that C. nudiflora has significant anti-cervicitis effects and the diterpenoids were most likely to be its active components. These data provide scientific support for the clinic usage of Luohuazizhu suppository and the development of new agents in treating cervicitis.

Abstract
Gonorrhea and chlamydia rates have risen to record-high levels in the United States over the past decade. Because these infections are often asymptomatic, effective clinical management relies on screening of asymptomatic patients, particularly women younger than 25 years and men who have sex with men. If undetected and untreated, gonorrhea and chlamydia can lead to infertility, ectopic pregnancy, and chronic pelvic pain and can facilitate HIV acquisition and transmission. Primary care providers need to be aware of recent changes in recommended treatments for both infections.

Abstract
These guidelines for the treatment of persons who have or are at risk for
sexually transmitted infections (STIs) were updated by CDC after consultation
with professionals knowledgeable in the field of STIs who met in Atlanta,
Georgia, June 11–14, 2019. The information in this report updates the
2015 guidelines. These guidelines discuss 1) updated recommendations for
treatment of Neisseria gonorrhoeae, Chlamydia trachomatis,
and Trichomonas vaginalis; 2) addition of
metronidazole to the recommended treatment regimen for pelvic inflammatory
disease; 3) alternative treatment options for bacterial vaginosis; 4) management
of Mycoplasma genitalium; 5) human papillomavirus vaccine
recommendations and counseling messages; 6) expanded risk factors for syphilis
testing among pregnant women; 7) one-time testing for hepatitis C infection; 8)
evaluation of men who have sex with men after sexual assault; and 9) two-step
testing for serologic diagnosis of genital herpes simplex virus. Physicians and
other health care providers can use these guidelines to assist in prevention and
treatment of STIs.

Abstract
Cervicitis is predominantly caused by Neisseria gonorrhoeae and Chlamydia trachomatis, which accounts for almost half of all the cases of cervicitis. The role of newer organisms like Mycoplasma genitalium and Ureaplasma sp. and association of bacterial load with cervicitis are also not well established. So the study aimed to determine the relative frequency of these organisms and their load in association with cervicitis cases from north India. A case-control study involving 300 women was conducted using quantitative real-time PCR from endocervical swabs for identification of organisms and quantification of bacterial load. Among 150 cervicitis cases, C. trachomatis, N. gonorrhoeae, M. genitalium and Ureaplasma parvum were detected in 5 (3·3%), 10 (6·6%), 37(24·6%) and 47 (31·3%) respectively. Old age (<0·001, chi-squared test) and irregular menstrual cycles (<0·001, chi-squared test) were significantly associated with cervicitis. M genitalium was the only organism to be associated significantly with cervicitis with regard to age (<0·031) and symptoms like discharge (P < 0·033, chi-squared test) and dysuria (P < 0·044, chi-squared test) in multivariate analysis. Our finding suggests that the bacterial load of these organisms is not significantly associated with cervicitis. However, we found significant association of M. genitalium infection with clinical characteristics of cervicitis cases.

Evaluation of the prevalence of sexually transmitted bacterial pathogens in Northern Cyprus by nucleic acid amplification tests, and investigation of the relationship between these pathogens and cervicitis. Turk J Obstet Gynecol 2020; 16:242-248. [PMID: 32231855 PMCID: PMC7090263 DOI: 10.4274/tjod.galenos.2019.80269] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 10/12/2019] [Indexed: 01/29/2023] Open
Abstract
Objective: To evaluate the prevalence of pathogens, Chlamydia trachomatis, Neisseria gonorrhea and Trichomonas vaginalis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Ureaplasma parvum in women via multiplex-polymerase chain reaction (PCR)-deoxyribonucleic acid (DNA). Materials and Methods: Cervical swabs of 273 women in reproductive age who underwent gynecologic examination in our outpatient clinic were evaluated using the multiplex-PCR-DNA method. The presence of cervicitis, contraceptive methods, marital status, and the number of partners were evaluated. Results: One hundred six (39%) of the 273 women had at least one bacterium, 25 women (9.8%) had two bacteria, and three women (1%) had three bacteria. U. urealyticum was the most frequently encountered bacterium (13.9%), followed by M. hominis (12.8%), U. parvum (12.4%), C. trachomatis (5.4%), M. genitalium (2.9%), N. gonorrhea (2.5%), and T. vaginalis (0.3%). Bacterial infection was detected more frequently in women aged <25 years, single, who had multiple partners, and clinically diagnosed with cervicitis. The cervicitis rate was 39% in our study. M. genitalium was significantly more frequent in women with cervicitis than in women without cervicitis (5.6 vs. 1.2%, p=0.005). C. trachomatis and N. gonorrhea, which are often associated with cervicitis, were comparable in women with and without cervicitis. Conclusion: Women with clinically diagnosed cervicitis or even with a normal-appearing cervix should be tested using multiplex-real-time PCR-nucleic-acidamplification tests on suspicion of such an infection. M. genitalium is an emerging bacterial agent for cervicitis along with C. trachomatis and N. gonorrhea.

Abstract
OBJECTIVE Ankaferd Blood Stopper (ABS) is a medicinal plant extract used topically as a hemostatic, anti-inflammatory, and anti-oxidant agent. Its cytoprotective effect mainly depends on its pleiotropic properties by modulating inflammatory mediators such as IL-1β, IL-6, and TNF-α. This study aims to test the possible therapeutic effect of ABS in the treatment of erosive and inflammatory conditions occurring in the uterine cervix. METHODS Twenty-four female Wistar Albino rats were used in the present study. Trichloracetic acid was applied intravaginally to establish an experimental rat model of cervicitis. The rats were randomly divided into three groups: group I (injury), group II (injury+isotoinc saline), and group III (injury+ABS). After 3 estrous cycles of ABS and isotonic saline treatment, the amount of inflammation, vascular congestion and erosion were evaluated in the cervical tissues by using a modified semi-quantitative scale of 0-3. Immunohistochemical staining with monoclonal antibodies against IL-1β was also performed. RESULTS Compared with group I and II, the ABS group showed the least inflammatory cell infiltration, vascular congestion and cervical erosion, compared with the ABS group prominent IL-1β staining observed in group I and group II. CONCLUSION Our data suggest that ABS is a highly effective alternative to induce normal cervical epithelium and can be used safely in the treatment of cervical inflammation with or without cervical erosion.

Abstract
OBJECTIVES To determine the microorganisms potentially involved in pelvic inflammatory diseases (PIDs) and the different diagnostic methods of PID. METHODS PubMed and International Guidelines search. RESULTS PIDs have various microbial causes. The pathogenic role of the main agents of sexually transmitted infections (STIs), Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium is well demonstrated (NP1). C. trachomatis is the most commonly described bacterium in PID (NP1), especially in women under 30 years old. PIDs also occur in situations that decrease the effectiveness of the cervix microbiological lock, such as bacterial vaginosis, allowing facultative vaginal bacteria such as Escherichia coli, Streptococcus agalactiae and anaerobes to ascend to the uterine cavity. Nevertheless, participation of the diverse bacteria of the vaginal microbiota, in particular anaerobes, and the polymicrobial character of PIDs are still differently appreciated. In the case of uncomplicated PID, to obtain a microbiological diagnosis, endocervical sampling is recommended during gynecological examination under speculum (grade B). A first swab allows for a smear on a slide for direct examination (Gram, MGG). A second swab, in an adapted transport medium, is useful for standard culture with N. gonorrhoeae and facultative vaginal flora bacteria cultures, with antibiotic susceptibility testing. A third swab, in an appropriate transport medium, allows for the search for N. gonorrhoeae, C. trachomatis, and if possible M. genitalium by nucleic acid amplification techniques (NAATs), (NP1). It is possible to only use one swab in a transport medium suitable for (i) survival of bacteria and (ii) NAATs. When the diagnosis of PID is clinically compatible, a positive NAAT for one or more of the three STI-associated bacteria on a genital sample supports the PID diagnosis (NP1). On the other hand, a negative NAAT does not allow the exclusion of an STI agent for PID diagnosis (NP1). In situations where speculum use is not possible, vaginal sampling will be performed by default. In case of complicated IGH, tuboperitoneal samples can be performed either radiologically or surgically. Since these sites are sterile, any bacteria present will be considered pathogenic (NP2). C. trachomatis serology is not interesting as a first line diagnostic tool for PID diagnosis and is not useful for monitoring the evolution of PID (NP1).

Abstract
Cervicitis is the inflammation of the cervix. It is usually caused by an infectious agent, usually sexually transmitted. Cervicitis is frequently asymptomatic and silent infection can cause complications of the upper genital tract. The symptoms are usually nonspecific, the most significant being an increase in vaginal discharge and/or intermenstrual bleeding. For its diagnosis, there are commercial systems based on molecular techniques that include almost all of the known pathogens associated with cervicitis, although cultures should not be abandoned due to the need to conduct studies of susceptibility to antibiotics. It is recommended to initiate an empirical antibiotic therapy that covers C.trachomatis and N.gonorrhoeae in the case of women at high risk of infection by these pathogens, especially if the follow-up is not assured or adequate diagnostic tests are not available. In women with low risk of sexually transmitted infection, antibiotic therapy should be adjusted to the results of the microbiological results.

Abstract
OBJECTIVE To assess the rates of co-infections between human papillomavirus (HPV) and 13 key markers of bacterial vaginosis in cervical samples by multiplex polymerase chain reaction in a population with a high rate of abnormal cytology and a positive HPV test. METHODS The study included a total of 213 women aged 18-72 years screened using Papanicolaou smears for determining cervical abnormalities and for HPV and bacterial vaginosis by single-target and multiplex polymerase chain reaction. RESULTS A total of 83 (39%) women were negative for intraepithelial lesion or malignancy cytology and 130 (61%) had abnormal cytology. HPV-DNA prevalence was 69.9% and bacterial vaginosis was 72.7 %. Co-infections between bacterial vaginosis with HPV-DNA and high-risk HPV were associated with an increased risk for squamous intraepithelial lesions of low-grade cytology and high-grade squamous intraepithelial lesions plus cervical cancer. The most frequent bacterial vaginosis agent was Gardnerella vaginalis (33.8%), and co-infection with HPV-DNA and high-risk HPV increased the risk for squamous intraepithelial lesions of low grade cytology and high-grade squamous intraepithelial lesions plus cervical cancer. Co-infection between Megasphaera type I and high-risk HPV increased the risk for high-grade squamous intraepithelial lesions plus cervical cancer. CONCLUSIONS Our results reinforce the hypothesis that some bacterial vaginosis agents may play a role as co-factors in HPV-mediated cervical carcinogenesis, at least in some populations.

Abstract
Reproductive tract infections have long been hypothesized to increase the risk of uterine fibroids. Few studies have been conducted, even for the common infection genital Chlamydia trachomatis (gCT), and only with self-reported gCT data. Our investigation used micro-immunofluorescence serology for gCT to characterize past exposure. We used cross-sectional enrollment data from a prospective fibroid study carried out in the Detroit, Michigan, area; ultrasound examinations systematically screened for fibroids. Participants were African-American women aged 23-34 years (recruited in 2010-2012). Age- and multivariable-adjusted logistic regression models were used to estimate odds ratios. A total of 1,587 women (94% of participants) had unequivocal gCT serology results; 22% had fibroids. Those who were seropositive for gCT were less likely to have fibroids (age-adjusted odds ratio = 0.68, 95% confidence interval: 0.54, 0.87; multivariable-adjusted odds ratio = 0.80, 95% confidence interval: 0.62, 1.03). Inverse associations were similar across categories of fibroid size, number, and total volume. Participant groups likely to have had multiple or severe infections (multiple serovar groups, more sex partners, clinically diagnosed chlamydia) all showed statistically significantly reduced odds of fibroids. A protective association of gCT with fibroids was unexpected but plausible. gCT infection might increase immune surveillance and eliminate early lesions. Further investigation on the relationship between fibroid development and reproductive tract infections is needed.

Abstract
Treatment with 1 G azithromycin was observed prospectively in 130 women with cervicitis (>30 polymorphonuclear leucocytes/high-powered field) enrolled in a cervicitis aetiology study of 558 women at three sexually transmitted infection clinics in Sydney, Australia. Two overlapping groups of women with cervicitis were considered: 'cervicitis group 1' (n = 116) excluded women with Trichomonas vaginalis and a subgroup of this, 'cervicitis group 2' (non-specific cervicitis) (n = 96) further excluded women with Neisseria gonorrhoea, Chlamydia trachomatis and Mycoplasma genitalium at enrolment. Testing for Chlamydia trachomatis, Mycoplasma genitalium and Trichomonas vaginalis was by PCR and Neisseria gonorrhoea by PCR and culture. Treatment outcomes were cervicitis or vaginal symptoms at follow-up. Effect on cervicitis at follow-up was also assessed after additional reported partner treatment. In 'cervicitis group 1' where prevalence of Mycoplasma genitalium and/or Chlamydia trachomatis was 23/116 (19.8%), azithromycin reduced cervicitis at follow-up (RR = 0.62 (95% CI 0.39-0.97) p = 0.035), but there was no significant effect in non-specific cervicitis ('cervicitis group 2') (RR = 0.60 (95% CI 0.35-1.01) p = 0.056). Empiric treatment did not reduce vaginal symptoms at follow-up in either group. No effect of empiric partner treatment was seen. The conclusion was that empiric azithromycin treatment of cervicitis reduces cervicitis at follow-up in populations with high prevalence of Chlamydia trachomatis and/or Mycoplasma genitalium. There are no benefits of empiric azithromycin for non-specific cervicitis or empiric partner treatment.

Abstract
OBJECTIVES Studies examining cervicitis aetiology and prevalence lack comparability due to varying criteria for cervicitis. We aimed to outline cervicitis associations and suggest a best case definition. METHODS A cross-sectional study of 558 women at three sexually transmitted infection clinics in Sydney, Australia, 2006-2010, examined pathogen and behavioural associations of cervicitis using three cervicitis definitions: 'microscopy' (>30 pmnl/hpf (polymorphonuclear leucocytes per high-powered field on cervical Gram stain)), 'cervical discharge' (yellow and/or mucopurulent cervical discharge) or 'micro+cervical discharge' (combined 'microscopy' and 'cervical discharge'). RESULTS Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Trichomonas vaginalis (TV) and Neisseria gonorrhoeae (NG) had the strongest associations with cervicitis definitions 'micro+cervical discharge': CT adjusted prevalence ratio (APR)=2.13 (95% CI 1.38 to 3.30) p=0.0006, MG APR=2.21 (1.33 to 3.69) p=0.002, TV APR=2.37 (1.44 to 3.90) p=0.0007 NG PR=4.42 (3.79 to 5.15) p<0.0001 and 'cervical discharge': CT APR=1.90 (1.25 to 2.89) p=0.003, MG APR=1.93 (1.17 to 3.19) p=0.011, TV APR=2.02 (1.24 to 3.31) p=0.005 NG PR=3.88 (3.36 to 4.48) p<0.0001. Condom use for vaginal sex 'always/sometimes' reduced cervicitis risk: ('micro+cervical discharge') APR=0.69 (0.51 to 0.93) p=0.016. Combined population attributable risk % (PAR%) of these four pathogens was only 18.0% with a protective PAR% of condoms of 25.7%. Exposures not associated with cervicitis included bacterial vaginosis, Mycoplasma hominis, Ureaplasma urealyticum, herpes simplex virus 1&2, cytomegalovirus, Candida, age, smoking and hormonal contraception. CONCLUSIONS Cervicitis was associated with CT, MG, TV and NG with combined PAR% of these pathogens only 18% in this setting, suggesting other factors are involved. Condoms significantly reduced cervicitis risk. Cervicitis definitions with best clinical utility and pathogen prediction were 'cervical discharge' and 'micro+cervical discharge'.

Abstract
OBJECTIVE Human β-defensin (hBD) is an innate immune mediator present in the mucosae. This study aimed to investigate whether hBD is implicated in nongonococcal cervicitis (NGC). MATERIALS AND METHODS Seventy-two patients with NGC and 64 healthy volunteers were consecutively enrolled between April 2010 and May 2011. Sensitive antimicrobial treatment was assigned to patients with NGC. Cervical tissues were sampled for the semiquantitative reverse transcription-polymerase chain reaction analyses of hBD-1, hBD-2, and hBD-3 messenger RNA (mRNA) expression. RESULTS The hBD-1, hBD-2, and hBD-3 mRNAs were comparably expressed in normal cervical tissues. The expression of hBD-1 mRNA was similar between patients with NGC and control subjects, whereas those of hBD-2 and hBD-3 mRNAs were significantly up-regulated in patients with NGC (1.25 [0.38] vs 1.08 [0.31], p = .005; 1.26 [0.35] vs 1.04 [0.30], p < .001). The relative expression level of hBD-1 mRNA remained unchanged in pathogen-eliminated patients, whereas those of hBD-2 mRNA (1.33 [0.42] vs 1.04 [0.36], p = .012) and hBD-3 mRNA (1.23 [0.32] vs 1.13 [0.26], p = .009) decreased significantly after the successful antimicrobial treatment. CONCLUSIONS Expressions of hBD-2 and hBD-3 mRNA are up-regulated in NGC, suggesting the role of mucosal immunity in NGC.

Abstract
We evaluated the performance and clinical utility of cervical microscopy for diagnosing genital gonorrhoea (GC) in women, using the APTIMA Combo 2 dual GC/Chlamydia trachomatis assay as the gold standard. Test performance was assessed overall and for patient subgroups (symptomatic, GC contacts, pelvic inflammatory disease [PID] diagnosis). It was found that 93 women had positive GC genital NAAT results; 15 had positive cervical microscopy (8 were GC contacts). In all subgroups except GC contacts, the PPV of cervical microscopy was below the nationally accepted target of 90%. Compared to APTIMA Combo 2, cervical microscopy has poor sensitivity for diagnosing GC in women (16.1% overall, 17.3% symptomatic, 25% GC contacts, 10.5% PID). GC contacts accounted for over 50% of the positive microscopy results and would have received epidemiological treatment for GC, regardless of the microscopy result. Discontinuing the routine use of cervical microscopy would improve patient flow through the sexual health clinic and resources could be utilised more effectively.

Abstract
Accurate knowledge of the composition and ecology of vaginal microbial environment of a healthy woman is necessary for the understanding of normal flora and how to reduce the risk for diseases. Vagina and its microflora form a balanced ecosystem in which dominated bacteria are vaginal lactobacilli. There are dynamic changes in this ecosystem having structure and composition depending on many factors. The term dysbacteriosis defines any movement outside the normal range for the given biotope of obligate and/or facultative microflora. Such a change in the quantity and quality of the respective microbial balance is fraught with danger and requires correction and recovery. The purpose of this overview is to examine obstetric and gynecological diseases that can cause vaginal impaired microbial balance. Vaginal dysbacteriosis is a cause, predecessor, and often also consequence of vaginal infections. In essence, any vaginal infection can be seen as dysbacteriosis, developed to the most severe extent. Here, there is a dominant microorganism other than lactic acid bacteria in the vagina (clinically manifested or not, respectively), depletion of defense mechanisms of the vagina associated with the shift of lactobacilli from their dominant role in the vaginal balance, decrease in their number and species diversity, and a resulting change in the healthy status of the vagina. Vaginal dysbacteriosis can be found in pathogenetic mechanism, whereby many obstetric and gynecological diseases develop. Most of these diseases lead directly to increased maternal and infant morbidity and mortality, so it is important to understand the reasons for them and the arrangements for their prevention.

Abstract
Cervicitis is a common clinical finding often attributed to sexually transmitted infections (STIs), but no etiologic agent is identified in the majority of cases. In this study, we comparatively assessed inflammation among the common infectious etiologies of cervicitis and assessed the potential value of liquid cytology specimens for predicting STIs. Among 473 Louisiana women at low risk for acquiring STIs, the prevalences of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in liquid-based cytology specimens were 1.5, 2.1, 0.6, and 4.4%, respectively. N. gonorrhoeae and human papillomavirus 18 (HPV18) infections were significantly more common among subjects infected with M. genitalium. Using direct microscopy, we observed significant increases in leukocyte infiltrates among subjects with monoinfections with M. genitalium or C. trachomatis compared to women with no detectable STIs. Inflammation was highest among subjects with M. genitalium. Using a threshold of ≥ 2 leukocytes per epithelial cell per high-powered field, the positive predictive values for M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis were 100, 70, 67, and 20%, respectively. Several novel M. genitalium genotypes were identified, all of which were predicted to be susceptible to macrolide antibiotics, suggesting that different strains may circulate among low-risk women and that macrolide resistance is substantially lower than in high-risk populations. This study highlights the capacity of M. genitalium to elicit cervical inflammation and, considering the strong epidemiologic associations between M. genitalium and human immunodeficiency virus (HIV), provides a potential mechanism for acquisition and shedding of HIV via chronic leukocyte recruitment to the cervical mucosa.

Abstract
Cervicitis has been described by some as the female counterpart of urethritis in men. Over the years a number of clinical and microscopy-based definitions have been suggested in the literature. Clinical manifestations include mucopurulent discharge from the cervix, cervical friability (easy bleeding from the cervix with passage of a swab) and cervical ectopy. Microscopic definitions involving the use of Gram stain of cervical secretions have included either more than 10 white blood cells (WBCs) or more than 30 WBCs per high-power field. Combinations of these clinical and microscopic findings have been used in attempts to increase the accuracy of cervicitis diagnosis. When cervicitis was initially recognized as a clinical entity, several investigators reported the primary pathogens causing cervicitis as Neisseria gonorrhoeae and Chlamydia trachomatis. It is now well established that most cases of cervicitis are not caused by these two organisms. Most cases of cervicitis are of unknown etiology.

Abstract
BACKGROUND Mucopurulent cervicitis (MPC) is a clinical syndrome characterized by mucopurulent discharge from the cervix and other signs of inflammation. This was a phase III, multicenter study designed to evaluate the effectiveness of placebo versus empiric antibiotic treatment for clinical cure of MPC of unknown etiology at 2-month follow-up. Unfortunately, enrollment was terminated because of low accrual of women with cervicitis of unknown etiology, but important prevalence and outcome data were obtained. METHODS Five hundred seventy-seven women were screened for MPC. Women with MPC were randomized to the treatment or placebo arm of the study, and the 2 arms were evaluated based on the etiology, clinical cure rates, adverse events (AEs), and rates of pelvic inflammatory disease. RESULTS One hundred thirty-one (23% [131/577]) screened women were found to have MPC. Eighty-seven were enrolled and randomized. After excluding women with sexually transmitted infections and other exclusions, 61% (53/87) had cervicitis of unknown etiology. The overall clinical failure rate was 30% (10/33), and the clinical cure rate was only 24% (8/33). Rates were not significantly different between the arms. There were 24 gastrointestinal AEs in the treatment arm compared with 1 AE in the placebo arm. CONCLUSIONS More than half of the cases of MPC were of unknown etiology. Clinical cure rates for the placebo and treatment arms were extremely low, with most women concluding the study with a partial response. Gastrointestinal AEs were higher in the treatment arm.

Abstract
Pelvic inflammatory disease (PID) is characterized by infection and inflammation of the upper genital tract in women and can cause significant reproductive health sequelae for women. Although a definitive diagnosis of PID is made by laparoscopic visualization of inflamed, purulent fallopian tubes, PID is generally a clinical diagnosis and thus represents a diagnostic challenge. Therefore, diagnosis and treatment algorithms advise a high index of suspicion for PID in any woman of reproductive age with pelvic or abdominal pain. Antibiotic therapy should be started early, and given for an adequate period of time to reduce the risk of complications. Coverage for anaerobic organisms should be considered in most cases.

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
Background Cervicitis is a syndrome of cervical inflammation and a common condition in female sex workers (FSW), a subpopulation vulnerable to sexually transmitted infections. Local data is essential for guiding syndromic management of cervicitis in FSW working in Peru. We sought to describe the prevalence and etiologies of cervicitis in this population. We also aimed to identify sociodemographic, behavioral and biological factors associated with cervicitis, including bacterial vaginosis (BV), a condition with a possible role in cervicitis. Methods FSW 18 years of age or older presenting to a free public sexual health clinic in Callao-Lima, Peru were eligible for inclusion upon consent. 467 participants completed a face-to-face questionnaire and underwent genital examination. Vaginal, endocervical and blood samples were collected and tested for C. trachomatis (CT), N. gonorrhea (GC), T. vaginalis (TV), BV, HIV and Human T-Cell Lymphotropic Virus −1. Logistic regression was used to determine whether sociodemographic, behavioral, or other sexual health related characteristics were associated with the diagnosis of cervicitis. Results Cervicitis was detected in 99 (24.9%) of 397 FSW. The presence of cervicitis was unable to be determined in 70 participants. In women with cervicitis, CT was present in 4.6% (4/87), TV in 4.0% (4/99), GC in 0% (0/87) and no pathogen was detected on cervical microbiology in 91.9% (91/99). BV was detected on vaginal microbiology in 36.9% (31/84) of cervicitis cases. BV was more common in women with cervicitis, however this association did not reach statistical significance (aOR = 1.47 [0.87, 2.48], p = 0.15). Other STI were not associated with cervicitis. Regular clinic attendance (aOR = 0.54 [0.34, 0.87], p = 0.01) and Ecuadorian nationality (aOR = 0.31 [0.13, 0.76], p = 0.01) were associated with reduced risk of cervicitis. Conclusions Cervicitis was common in FSW working Peru and was predominantly nongonococcal and non-chlamydial in etiology. Further study is warranted to clarify the role of BV and other emerging cervicitis pathogens in this population. The current Peruvian program of free health checks for FSW may be effective for reducing rates of cervicitis. The protective effect of Ecuadorian nationality prompts further study.

Abstract
Pelvic inflammatory disease (PID) is caused by a large spectrum of micro-organisms. However, the microbiological cause is unknown in approximately half of cases according to varying series. In the context of sexually transmitted disease (STD), the most frequently identified microorganisms causing PID are Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium. In such cases, bacterial vaginosis and Trichomonas vaginalis are frequently associated. In case of complicated PID or when PID is the consequence of delivery, abortion, intra-uterine procedure, bacteria that come from vaginal carriage may be encountered: Enterobacteriacae, Staphylococcus spp., Streptococcus spp., anaerobes. Mycopslama hominis as well as Ureaplasma urealyticum may also be found in this context. The microbiological diagnosis may be performed on samples of vaginal liquid, endocervix or, when available, surgical specimens. The microbiological diagnostic procedures that are used to identify these microrgansims are reviewed. Vaginal sampling may help to identify N. gonorrhoeae, C. trachomatis and M. genitalium using nucleic acid amplification tests (NAAT), and is also of interest because of the epidemiological association of PID to bacterial vaginosis and trichomoniasis. Samples from the endocervix, and if available, from endometrial biopsy surgical procedures, should be processed to detect N. gonorrhoeae, C. trachomatis and M. genitalium using NAAT, and to search for the presence of Neisseria gonorrhoeae (antibiogram should be performed), facultative anaerobes, anaerobes and capnophilic bacteria. The antibiotic treatment should at least cover N. gonorrhoeae, C. trachomatis and M. genitalium, and for most of the authors, anaerobes. In case, microbiological studies demonstrate the role of other bacteria (e.g., Enterobacteriacae), theses should be treated according to the results of antibiogram.

Abstract
Sexually transmitted diseases (STDs) in women are of great concern to all health-care providers since many of them are preventable and/or treatable conditions which, if left untreated, could have serious sequelae such as pelvic inflammatory disease, infertility, cervical cancer, systemic disease, etc. They may also become a major public health problem when dealing with diseases such as hepatitis, etc., or in people with human immunodeficiency virus. We present here a comprehensive review of the common causes of STDs and their treatment.

Abstract
BACKGROUND Sexually transmitted infections (STIs) are associated with an increased risk of HIV infection. To model the interaction between STIs and HIV infection, we evaluated the capacity of the pigtail macaque model to sustain triple infection with Trichomonas vaginalis, Chlamydia trachomatis, and SHIV(SF162P3). METHODS Seven SHIV(SF162P3) -infected pigtail macaques were inoculated with T. vaginalis only (n = 2), C. trachomatis only (n = 1), both T. vaginalis and C. trachomatis (n = 2), or control media (no STI; n = 2). Infections were confirmed by culture and/or nucleic acid testing. Genital mucosa was visualized by colposcopy. RESULTS Characteristic gynecologic signs were observed for both STIs, but not in control animals. Manifestations were most prominent at days 7-10 post-infection. STIs persisted between 4 and 6 weeks and were cleared with antibiotics. CONCLUSIONS These pilot studies demonstrate the first successful STI-SHIV triple infection of pigtail macaques, with clinical presentation of genital STI symptoms similar to those observed in humans.

Abstract
We investigated the relative frequencies of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Mycoplasma hominis and Ureaplasma sp. in cervical samples. PCR analyses were performed in ectocervical and endocervical samples from 224 patients attending public health services in Belo Horizonte and Contagem, Minas Gerais Brazil. A high prevalence of colonisation of the cervix (6.3% for C. trachomatis, 4.0% for N. gonorrhoeae, 0.9% for M. genitalium, 21.9% for M. hominis, 38.4% for Ureaplasma sp.) was demonstrated not only for pathogens classically associated to cervicitis (C. trachomatis and N. gonorrhoeae), but also for M. hominis and Ureaplasma sp. These findings may be useful to guide more adequate diagnosis to interrupt transmission and to avoid negative impacts on the female reproductive tract.

Abstract
Mycoplasma genitalium is an emerging sexually transmitted pathogen implicated in urethritis in men and several inflammatory reproductive tract syndromes in women including cervicitis, pelvic inflammatory disease (PID), and infertility. This comprehensive review critically examines epidemiologic studies of M. genitalium infections in women with the goal of assessing the associations with reproductive tract disease and enhancing awareness of this emerging pathogen. Over 27,000 women from 48 published reports have been screened for M. genitalium urogenital infection in high- or low-risk populations worldwide with an overall prevalence of 7.3% and 2.0%, respectively. M. genitalium was present in the general population at rates between those of Chlamydia trachomatis and Neisseria gonorrhoeae. Considering more than 20 studies of lower tract inflammation, M. genitalium has been positively associated with urethritis, vaginal discharge, and microscopic signs of cervicitis and/or mucopurulent cervical discharge in seven of 14 studies. A consistent case definition of cervicitis is lacking and will be required for comprehensive understanding of these associations. Importantly, evidence for M. genitalium PID and infertility are quite convincing and indicate that a significant proportion of upper tract inflammation may be attributed to this elusive pathogen. Collectively, M. genitalium is highly prevalent in high- and low-risk populations, and should be considered an etiologic agent of select reproductive tract disease syndromes in women.

Abstract
Chlamydia trachomatis is a prevalent sexually transmitted infection that can lead to serious reproductive morbidity. Management and control of C. trachomatis is a challenge, largely due to its asymptomatic nature and our incomplete understanding of its natural history. Although chlamydia screening programs have been implemented worldwide, several countries have observed increasing rates of reported chlamydia cases. We reviewed the literature relating to the long-term complications of C. trachomatis, as well as screening strategies, treatment, and prevention strategies for reducing chlamydia in the population. Articles from 1950-2010 were identified through a Medline search using the keyword "Chlamydia trachomatis" combined with "screening", "pelvic inflammatory disease", "endometritis", "salpingitis", "infertility", "ectopic pregnancy", "urethritis", "epididymitis", "proctitis", "prostatitis", "reinfection", "cost-effectiveness", "treatment", "vaccines", or "prevention". Progression of C. trachomatis varies, and recurrent infections are common. Currently, there is limited evidence on the effectiveness of chlamydia screening. Higher quality studies are needed to determine the efficacy of more frequent screening, on a broader range of sequelae, including infertility and ectopic pregnancy, in addition to pelvic inflammatory disease. Studies should focus on delineating the natural history of recurrent infections, paying particular attention to treatment failures. Furthermore, alternatives to screening, such as vaccines, should continue to be explored.

Abstract
BACKGROUND Vaginal HIV-1 shedding has been associated with Trichomonas vaginalis (TV) infection and could play a role in HIV transmission. The purpose of the study was to examine if effective TV treatment reduces the presence of vaginal HIV-1 RNA. METHODS TV+ women attending an HIV outpatient clinic in New Orleans, LA, who resolved infection (n = 58) and TV-negative controls (n = 92), matched on antiretroviral therapy (ART) were examined and interviewed at baseline, 1, and 3 months. TV status was tested by culture and the amount of cell free HIV-1 RNA in the vaginal fluids was determined by the Amplicor HIV-1 Monitor ultrasensitive assay. RESULTS : Most women (81.3%) were black and the mean age was 37.5 (SD 8.7). At baseline, 46.0% had plasma HIV-1 RNA >/=10,000 copies/mL, 26.4% had CD4<200 cells/muL, 54.7% were taking ART, and only 26.0% had detectable HIV-1 RNA in their vaginal fluids. TV-positive women who were effectively treated for TV were less likely to shed HIV vaginally at 3-months post-treatment compared to baseline (R.R. 0.34, 95% CI: 0.12-0.92, P = 0.03), whereas there was no change for TV-negative women. CONCLUSION This study provides additional support that reducing TV infection among HIV-positive women may have an impact on the prevention of HIV transmission. Reasons for the delayed treatment effect and the effect on cervical shedding need further investigation.

Abstract
BACKGROUND The mechanism of human immunodeficiency virus (HIV) transmission via heterosexual intercourse is unknown. We sought to determine whether the presence of inflammatory cells in the vagina is associated with the presence of genital tract HIV type 1 (HIV-1) RNA. METHODS Analysis of a longitudinal prospective cohort was performed. Women with HIV-1 infection were assessed with use of paired plasma and cervicovaginal lavage specimens. Viral load measurements were performed using nucleic acid sequence-based amplification. White blood cells found in the genital tract (GT WBCs) were quantified using a hemacytometer. Common lower genital tract infections assessed for association with viral shedding (i.e., genital tract viral load [GTVL]) included bacterial vaginosis, candidiasis, and trichomoniasis. Generalized estimating equations were used to estimate the prevalence and odds of detectable GTVL by GT WBC. The association was examined both in the presence and in the absence of lower genital tract infections. RESULTS A total of 97 women and 642 visits were included in the analysis. Median duration of follow-up was 30.4 months. Thirty women (31%) had detectable GTVL at any visit. The median CD4 cell count at baseline was 525 cells/muL. Most women were antiretroviral therapy naive at baseline. After adjustment for plasma viral load, the odds of detectable GTVL increased as GT WBC increased, with an odds ratio of 1.36 (95% confidence interval, 1.1-1.7) per 1000-cell increase in GT WBC among women without lower genital tract infections. After adjustment for plasma viral load and lower genital tract infections by incorporating them in a regression model, GT WBC remained significantly associated with GTVL, with an adjusted odds ratio of 1.22 (95% confidence interval, 1.08-1.37). CONCLUSIONS The presence of GT WBC is associated with an increased risk of detectable GTVL.

Abstract
PURPOSE OF REVIEW Sexually transmitted infections impact significantly on global health. Whereas Chlamydia, Neisseria gonorrhoea and syphilis have been extensively examined, there remains a paucity of knowledge of nonchlamydial and nongonococcal cervicitis, an arguably more prevalent but poorly characterized condition with uncertain clinical implications. With increasing application of molecular diagnostic methods for the detection of sexually transmitted infections and a growing body of literature on cervicitis, a review is timely. RECENT FINDINGS The number of putative aetiological agents implicated in cervicitis is growing and includes Mycoplasma genitalium, herpes simplex virus, cytomegalovirus, bacterial vaginosis and Trichomonas. The potential role of cervicitis in HIV transmission has been highlighted. Increasing broad-spectrum antibiotic usage with associated emergence of antimicrobial resistance reinforces the need for targeted antibiotic therapies, including the management of cervicitis. SUMMARY As our understanding of the aetiology and significance of cervicitis, particularly nonspecific cervicitis, improves, management will be refined. Advances in molecular diagnostic testing will facilitate this process, but urinary nucleic acid amplification testing should not replace clinical examination while cervicitis prevalence and significance is not yet established. A standardized approach to cervicitis research, particularly with consensus of case definition, may facilitate outcomes that can be more generally applied in clinical practice.
