Moxifloxacin monotherapy for treatment of uncomplicated pelvic inflammatory disease: A systematic review and meta-analysis with trial sequential analysis of randomized controlled trials. Pharmacoepidemiol Drug Saf 2023; 32:1189-1199. [PMID: 37655831 DOI: 10.1002/pds.5677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 07/03/2023] [Accepted: 07/28/2023] [Indexed: 09/02/2023]
Abstract
PURPOSE The aim of this study was to evaluate the efficacy and safety of moxifloxacin monotherapy for the treatment of uncomplicated pelvic inflammatory disease (uPID). METHODS The literatures from PubMed, ScienceDirect, Google Scholar, Cochrane library and the http://clinicaltrials.gov/ were retrieved until February 2023. Only randomized controlled trials (RCTs) comparing the efficacy and safety of moxifloxacin with other antibiotics for treating uPID were included. The primary outcomes were clinical cure rate (CCR), bacteriological success rates (BSR) and risk of drug-related adverse events (AEs). We used random-effects modelled meta-analysis, trial sequential analysis, and the Grading of Recommendations Assessment, Development, and Evaluation. This study was registered in the International Prospective Register of Systematic Reviews (registration number: CRD42023428751). RESULTS A total of four RCTs that enrolled 3201 women patients with uPID were included. In the per-protocol populations, no significant difference was observed between patients given moxifloxacin and those given other antibiotics with regard to CCR at test-of-cure (TOC) (2485 patients, odds ratio [OR] = 0.84, 95% confidence interval [CI] 0.68-1.04, p = 0.12). Similarly, there was no statistically significant difference between patients given moxifloxacin and those given other antibiotics in terms of BSR at TOC (471 patients, OR = 1.17, 95% CI 0.70-1.96, p = 0.56) in the microbiologically valid population. However, drug-related AEs occurred less frequently with moxifloxacin than with other antibiotics (2973 patients, OR = 0.74, 95% CI 0.64-0.86, p < 0.0001), especially gastrointestinal AEs (2973 patients, OR = 0.59, 95% CI 0.47-0.74, p < 0.00001). CONCLUSIONS In the treatment of uPID, moxifloxacin monotherapy can achieve similar efficacy as other combination therapy regimens. Moreover, moxifloxacin had a better safety profile than that of comparators. Based on its additional advantages (i.e., better safety profile, no dosage adjustment and better compliance), moxifloxacin may be a more fascinating option compared with the currently used regimens.

Abstract
Most sexually transmitted infections (STIs) can be accurately diagnosed and treated during asymptomatic carriage. Widespread screening for these STIs is therefore assumed to be an effective way to reduce their prevalence and associated disease. In this review, we provide evidence that this is the case for HIV and syphilis. However, for other STIs such as Neisseria gonorrhoeae and Chlamydia trachomatis, our review reveals that the evidence that screening reduces infection prevalence and associated disease is weak. There is also growing evidence of harms from screening that might outweigh any benefits. The harms include the increased consumption of antimicrobials that follows frequent screening and increased detection of asymptomatic STIs in key populations, such as men who have sex with men taking HIV pre-exposure prophylaxis, and associated risk of antimicrobial resistance in target and non-target organisms. There may also be psycho-social harm associated with an STI diagnosis. We conclude that in the absence of symptoms, in high STI prevalence populations frequent STI screening should be limited to HIV and syphilis.

Abstract
The microbial ecosystem of the female urogenital tract is composed of many niche microenvironments across multiple organ systems in the urinary and reproductive tract. It is complex and contains a variety of bacteria, archaea, viruses, yeast, and protozoa-Many of which are still unidentified or whose functionality is unknown. Unlike the gut microbiome, whose composition is relatively stable in the absence of external perturbations, the urogenital microbiome is constantly shifting in response to biological cycles such as hormonal fluctuations during menstruation. Microbial composition differs between women but the dominance of some microbial families, such as Lactobacillaceae and other lactic acid-producing bacteria, are shared. Research suggests that it is difficult to define a universal healthy urogenital microbiome and consequently map a path to recovery from disease due to dysbiosis. Due to its temporal shifts, the female urogenital microbiome offers a unique opportunity to examine the biological mechanisms that work to restore a microbiome to its baseline. Common functional disorders in women's health are often difficult to diagnose and treat, are prone to recurrence, and can lead to subfertility or infertility. Knowledge of the interconnected microorganism communities along the continuum of the female reproductive tract could revolutionize the quality of women's healthcare.

Abstract
Mycoplasma genitalium (MG) and Chlamydia trachomatis (CT) are the most common sexually transmitted pathogens, which can cause cervicitis, pelvic inflammation and infertility in female. In the present study, we collected the basic information, clinical results of leucorrhoea and human papillomavirus (HPV) infection of patients, who were involved in both MG and CT RNA detection in West China Second Hospital of Sichuan University from January 2019 to April 2021, ranging from 18 to 50 years old. The results showed that the infection frequencies of MG and CT were 2.6% and 6.5%, respectively. The infection rate of CT in gynaecological patients was significantly higher than that of MG (P < 0.001). Moreover, patients with CT infection often had symptoms of gynaecological diseases, while patients with MG infection remain often asymptomatic. By exploring the connection between MG or CT infection and vaginal secretions, we found that the infection of MG or CT promoted to the increase of vaginal leukocytes, and CT infection exacerbated the decrease of the number of Lactobacillus in the vagina. Further analysis suggested that independent infection and co-infection of MG or CT resulted in abnormal vaginal secretion, affecting the stability of vaginal environment, which may induce vaginal diseases. Unexpectedly, our study found no association between MG or CT infection and high-risk HPV infection. In conclusion, our study explored the infection of MG and CT among women in Southwest China for the first time, and revealed that the infection of MG or CT would affect the homeostasis of vaginal environment, which laid a foundation for the clinical diagnosis and treatment of MG and CT infection.

Abstract
BACKGROUND Pelvic inflammatory disease (PID) is an infection of the upper female reproductive organs that can lead to infertility and ectopic pregnancies. It is a reportable condition in North Carolina (NC) but is likely underreported. We aimed to quantify PID diagnoses in NC emergency department (ED) visits. METHODS The NC Disease Event Tracking and Epidemiology Collection Tool tracks all ED visits in NC. We identified PID diagnoses among women of reproductive age (15-44 years) between 2008 and 2017 using International Classification of Diseases, Ninth/Tenth Revision, Clinical Modification codes, and calculated the yearly proportion with PID diagnoses. We assessed the number of PID visits per patient each year, and the proportion of ED visits with a PID diagnosis by age, proportion of the patient's ZIP code living below the poverty line, insurance coverage, and NC provider region. RESULTS The percent of women with PID decreased from 6189 (1.0%) in 2008 to 4337 (0.58%) in 2016 before increasing slightly to 4371 (0.61%) in 2017. We identified 54,502 (0.45%) ED visits among 51,847 (0.76%) women with ≥1 PID diagnosis code. Most (95.5%) women with PID had one ED visit during the calendar year. Each year, the proportion with PID was highest among women aged 20 to 24 years, covered under public insurance, from the most impoverished areas, and whose provider was in the Coastal region of NC. CONCLUSIONS The percent with PID among women visiting EDs decreased between 2008 and 2017 in NC. Although this decline was observed across all demographics, disparities associated with PID continued to persist over time.

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.

Characteristics of pelvic inflammatory disease caused by sexually transmitted disease - An epidemiologic study. J Gynecol Obstet Hum Reprod 2021; 50:102176.

Abstract
INTRODUCTION Pelvic inflammatory disease (PID) is an infection of the upper genital organs, diagnosed by clinical findings. The nucleic acid amplification test (NAAT) identify sexually transmitted (STD) pathogens from endocervical swabs, via real time PCR. This study explored the prevalence of STD detected by NAAT for women with PID. We also aimed to identify predictive characteristics for positive test. MATERIAL & METHODS This retrospective cohort study explored the prevalence of positive NAAT for women with clinically diagnosed PID, 2016-2019, in a secondary referral center. The primary outcome was the prevalence of positive STD tests and specific pathogens. The secondary outcome was predictive clinical and laboratory parameters for positive NAAT. RESULTS Among the 610 women in our cohort, 103 had a positive STD PCR, which accounts for 17%. Most of the patients had Urea parvum (39.4%) Mycoplasma hominis (17.2%) or Urea urealyticum (15.7%). Other pathogens with lower incidence were Chlamydia trachomatis (9.8%), Trichomonas vaginalis (3.4%), Mycoplasma genitalium (2.1%) and the lowest rate was for Neisseria gonorrhea (1.5%). CONCLUSION In our population, we found lower prevalence of Chlamydia trachomatis and Neisseria gonorrhea compared to other large populations. This may be due to a high prevalence of married and religious women and also due to administration of a wide range of empirical antibiotic treatment, even for a low suspicion of PID. The study also gives reassurance that our empirical antibiotic protocol is adjusted to the endemic PID pathogens found in our population.

Abstract
Background Pelvic inflammatory disease (PID) is the inflammation of the adnexa of the uterus, that mainly manifests in a subclinical/chronic context and goes largely underreported. However, it poses a major threat to women’s health, as it is responsible for infertility and ectopic pregnancies, as well as chronic pelvic pain. Previous studies in Jordan have not reported PID, attributed mainly to the social structure of the country which largely represents a sexually conservative population. Our study aims to report the clinical symptoms that point towards PID and investigate the major risk determinants for the Jordanian population, in a cross-sectional study, using our scoring system based only on clinical data and examination. Methods One hundred sixty-eight consecutive adult women that came in the Outpatient Clinics of Gynaecological Department of the Jordan University Hospital were interviewed and their medical history and symptoms were registered and analysed. A Score for PID symptoms, we developed, was given to each woman. Results and correlations were then statistically tested. Results Our study population consisted of relatively young women (37.7 ± 11) that had their first child at an average age of 24.1 (± 4.8) and a mean parity of 3.1 (± 2.2). Fifty-eight women (34.5%) reported having undergone at least one CS, while the mean PID Symptom Score was 3.3 (± 2.3). The women in our study exhibited 8 symptoms of PID, namely dysmenorrhea and vaginal discharge; being the commonest (45.2% and 44.6% respectively), in addition to chronic pelvic pain, pelvic heaviness, menorrhagia, dyspareunia, urinary symptoms, and smelly urine. They also reported history of 3 conditions that can be attributed to PID, that is infertility, preterm labour, and miscarriages. Conclusions Our PID Scoring System seems to identify the risk factors of PID and predict well the PID likelihood. This score predicts that women with higher parity, who used contraceptives and underwent any invasive medical procedure are expected to score higher in the PID Symptom Score. Our data also suggest that PID should not be ruled out in the Jordanian population when symptoms are compatible to this diagnosis. As a sexually conservative country, Jordan is thought to have a low prevalence of pelvic inflammatory disease. The prevalence of STD pathogens is very low, however many patients present symptoms of PID, so we randomly interviewed 168 healthy participants and investigated symptoms related to PID. Surprisingly the percentage of participants who had symptoms of PID was high, reaching up to 64% for some symptoms. We then created a PID symptom score; where every symptom gets one mark (1–11), and tested it for association against independent factors. As a result, it can be predicted that a woman with higher parity, who used contraceptives, and underwent E & C, D & C, HSG, or Hysteroscopy is expected to score higher in the PID Symptom Score. This result draws the attention to PID incidence in similar conservative communities, and therefore further research is needed to confirm the prevalence of PID and identify the causative factors.

Abstract
Bacterial vaginosis, pelvic inflammatory disease, and endometritis are infections of the genital tract that can lead to many adverse health outcomes, including infertility. Bacterial vaginosis is characterized by a lower prevalence of lactobacilli and a higher prevalence of anaerobic bacteria, including Gardnerella vaginalis, Megasphaera spp., and Atopobium vaginae. Endometritis and pelvic inflammatory disease are caused by the ascension of pathogenic bacteria to the uterus, although the mechanisms by which they do so are unclear. Bacterial vaginosis, chronic endometritis, and pelvic inflammatory disease have been linked to infertility in retrospective and prospective trials. Similarly, the causes of bacterial vaginosis and endometritis-related infertility are likely multifactorial and stem from inflammation, immune targeting of sperm antigens, the presence of bacterial toxins, and increased risk of sexually transmitted infections. Diagnosis and treatment of bacterial vaginosis, chronic endometritis, and pelvic inflammatory disease before attempting conception may be important components of preconceptional care for symptomatic women to improve outcomes of natural and assisted reproduction.

Abstract
BACKGROUND Mycoplasma genitalium is an increasingly recognized cause of pelvic inflammatory disease (PID). CASE A 17-year-old female adolescent presented with chronic pelvic pain and dysmenorrhea. Test results for Chlamydia trachomatis and Neisseria gonorrhea were negative, and multiple radiologic test results were normal. The patient failed several empiric courses of therapy over 1 year. Laparoscopy revealed findings consistent with PID. Nucleic acid amplification test results were positive for M genitalium. SUMMARY AND CONCLUSION M genitalium causing PID can be challenging to diagnose because of its often atypical presentation. Further epidemiological studies are needed to understand the burden of disease and to establish testing and treatment guidelines.

Abstract
Mycoplasma genitalium is a fastidious organism of the class Mollicutes, the smallest prokaryote capable of independent replication. First isolated in 1981, much is still unknown regarding its natural history in untreated infection. It is recognized as a sexually transmitted pathogen causing acute and chronic non-gonococcal urethritis (NGU) in men, with a growing body of evidence to suggest it also causes cervicitis and pelvic inflammatory disease in women. Its role in several other clinical syndromes is uncertain. The majority of people infected remain asymptomatic and clear infection without developing disease; asymptomatic screening is therefore not recommended. Prevalence rates are higher in patients attending sexual health clinics and in men with NGU. Limited availability of diagnostics has encouraged syndromic management, resulting in widespread antimicrobial resistance and given that few antimicrobial classes have activity against M. genitalium, there is significant concern regarding the emergence of untreatable strains. There is a need for wider availability of testing, which should include detection of macrolide resistance mediating mutations. Expertise in interpretation of microbiological results with clinical correlation ensures targeted treatment avoiding unnecessary antibiotic exposure. Public health surveillance nationally and internationally is vital in monitoring and responding to changing epidemiology trends. In this review, we summarize current knowledge of M. genitalium, including epidemiology, clinical and microbiological data, and discuss treatment challenges in the era of rising multidrug resistance.

Abstract
OBJECTIVE Many sexually transmitted infections increase risk of mother-to-child transmission (MTCT) of HIV, but the effect of Mycoplasma genitalium is not known. We hypothesized that M. genitalium infection would be common among HIV-infected pregnant women and could be associated with in-utero and intrapartum MTCT. DESIGN Observational case-cohort study. METHODS The current study used specimens from a Kenyan perinatal MTCT cohort (1999-2005) involving HIV-infected women and their infants, who received short-course zidovudine for prevention of MTCT. Vaginal swabs collected at 32 weeks gestation were tested for M. genitalium using a transcription-mediated amplification assay. Infant perinatal HIV infection was determined at birth and 4 weeks of age by DNA PCR. Using a case-cohort design, a random sample was generated with 3 : 1 control : case ratio; prevalence and correlates of M. genitalium were assessed with chi-squared and t tests; predictors of infant outcomes were analyzed using logistic regression. RESULTS Among 220 HIV-infected pregnant women evaluated, 47 women (21.4%) had M. genitalium. Antenatal M. genitalium infection was associated with higher HIV RNA in plasma (5.0 vs. 4.6 log10 copies/ml in M. genitalium-positive vs. M. genitalium-negative women, P = 0.02) at 32 weeks. Women with M. genitalium were less likely to report prior sexually transmitted infections and genital ulcers (both P = 0.05). There was no association found between exposure to M. genitalium and perinatal MTCT (odds ratio = 0.72, 95% confidence interval 0.35, 1.51, P = 0.39). CONCLUSION Vaginal M. genitalium infection was frequently detected among Kenyan HIV-infected pregnant women and was associated with higher plasma HIV levels, but was not associated with perinatal transmission of HIV.

The association between sociodemographic, hormonal, tubo-ovarian factors and bacterial count in Chlamydia and Mycoplasma infections with infertility. Saudi J Biol Sci 2019; 26:20-23. [PMID: 30622402 PMCID: PMC6318781 DOI: 10.1016/j.sjbs.2016.11.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2016] [Revised: 10/26/2016] [Accepted: 11/06/2016] [Indexed: 11/21/2022] Open
Abstract
Aim: To determine if there is an association between the Chlamydia and Mycoplasma infections with socio-demographic and clinical factors, and also with infertility. Methods: We conducted a study on 100 infertile married women and 100 control group, and collected data on the socio-demographic, hormonal and tubo-ovarian factors. The results of the endocervical swabs were analyzed for Mycoplasma and Chlamydia infection, the bacterial counts were also determined. Results: The percentage positivity to infection was significantly more among the infertile group compared to the control group, and also significantly more among the age group <30 years old. The positivity for infection with Chlamydia and/or Mycoplasma was significantly correlated with age, history of irregular menstruation, and history of previous abortion. Further sub-analysis of the infertile group showed that positivity to Chlamydia and/or Mycoplasma infection was significantly correlated to hormonal factors, ovarian factors, irregular menstruation, and previous abortion. Regression analysis showed that hormonal, ovarian factors, and irregular menstruation were the most significant factors in the positivity to Chlamydia and Mycoplasma infection. Bacterial count was significantly correlated with age, history of irregular menstruation, and history of previous abortion. Conclusion: Infection to Chlamydia and Mycoplasma is associated to younger age (⩽30 years old), and occurs in the infertile women. There is an interplay between infection in younger women, irregular menstruation, hormonal, and tubo-ovarian factors with infertility. Bacterial count was significantly correlated with age, history of irregular menstruation, and history of previous abortion.

The vaginal microbiota and its association with human papillomavirus, Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium infections: a systematic review and meta-analysis. Clin Microbiol Infect 2018; 25:35-47. [PMID: 29729331 DOI: 10.1016/j.cmi.2018.04.019] [Citation(s) in RCA: 92] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2017] [Revised: 04/16/2018] [Accepted: 04/19/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND The vaginal microbiota may modulate susceptibility to human papillomavirus (HPV), Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium infections. Persistent infection with a carcinogenic HPV is a prerequisite for cervical cancer, and C. trachomatis, N. gonorrheae and M. genitalium genital infections are all associated with pelvic inflammatory disease and subsequent infertility issues. OBJECTIVES To evaluate the association between these infections and the vaginal microbiota. DATA SOURCES The search was conducted on Medline and the Web of Science for articles published between 2000 and 2016. STUDY ELIGIBILITY CRITERIA Inclusion criteria included a measure of association for vaginal microbiota and one of the considered STIs, female population, cohort, cross-sectional and interventional designs, and the use of PCR methods for pathogen detection. METHODS The vaginal microbiota was dichotomized into high-Lactobacillus vaginal microbiota (HL-VMB) and low-Lactobacillus vaginal microbiota (LL-VMB), using either Nugent score, Amsel's criteria, presence of clue cells or gene sequencing. A random effects model assuming heterogeneity among the studies was used for each STI considered. RESULTS The search yielded 1054 articles, of which 39 met the inclusion criteria. Measures of association with LL-VMB ranged from 0.6 (95% CI 0.3-1.2) to 2.8 (95% CI 0.3-28.0), 0.7 (95% CI 0.4-1.2) to 5.2 (95% CI 1.9-14.8), 0.8 (95% CI 0.5-1.4) to 3.8 (95% CI 0.4-36.2) and 0.4 (95% CI 0.1-1.5) to 6.1 (95% CI 2.0-18.5) for HPV, C. trachomatis, N. gonorrhoeae and M. genitalium infections, respectively. CONCLUSIONS Although no clear trend for N. gonorrhoeae and M. genitalium infections could be detected, our results support a protective role of HL-VMB for HPV and C. trachomatis. Overall, these findings advocate for the use of high-resolution characterization methods for the vaginal microbiota and the need for longitudinal studies to lay the foundation for its integration in prevention and treatment strategies.

Abstract
BACKGROUND The association of mycoplasma genitalium (M. genitalium) with infertility has been documented. The infections are asymptomatic and difficult to diagnose. Understanding the associated risk factors will help in facilitating better screening measures for at-risk groups. OBJECTIVE The aim was to determine the prevalence of, and risk factors for, M. genitalium infection among infertile women in Ibadan. MATERIALS AND METHODS In this cross-sectional study, 402 women (267 infertile and 135 fertile) referred to 2 hospitals in Ibadan between March and November 2015 were enrolled. Information was obtained, using structured questionnaire, on sociodemographic and behavioral characteristics of the respondents while endocervical swabs were obtained for detection of M. genitalium. MgPa gene was diagnosed using the conventional Polymerase chain reaction. Bands corresponding to 495kb were documented as positive for M. genitalium. RESULTS Among the infertile women, 43 (16.1%) had evidence of M. genitalium infection as against 3 (2.2%) of women without infertility (p<0.001). Associated risk factors included having more than one lifetime sexual partner (OR=10.13, 95% CI: 3.76-33.97); husbands having other sexual partners (OR=12.88, 95% CI: 2.08-90.63); being a serial monogamist (OR=6, 95% CI: 4.35-8.27) and low socio-economic status (OR=2.80, 95% CI: 1.28-6.10). No relationship exists between the previous history of sexually transmitted infections and M. genitalium. CONCLUSION The risk factors for M. genitalium infection are similar to those peculiar to other sexually transmitted infections. Its routine screening should be incorporated into the current protocol for microbiological evaluation of infertile women.

Abstract
Female infertility, including tubal factor infertility, is a major public health concern worldwide. Most cases of tubal factor infertility are attributable to untreated sexually transmitted diseases that ascend along the reproductive tract and are capable of causing tubal inflammation, damage, and scarring. Evidence has consistently demonstrated the effects of Chlamydia trachomatis and Neisseria gonorrhoeae as pathogenic bacteria involved in reproductive tract morbidities including tubal factor infertility and pelvic inflammatory disease. There is limited evidence in the medical literature that other sexually transmitted organisms, including Mycoplasma genitalium, Trichomonas vaginalis, and other microorganisms within the vaginal microbiome, may be important factors involved in the pathology of infertility. Further investigation into the vaginal microbiome and other potential pathogens is necessary to identify preventable causes of tubal factor infertility. Improved clinical screening and prevention of ascending infection may provide a solution to the persistent burden of infertility.

Abstract
The study was performed to investigate the prevalence of Chlamydia trachomatis and Mycoplasma genitalium in a population of infertile couples from Iran and how this relates to tubal factor infertility, pregnancy rate and outcome of pregnancy. Blood, semen and first-void urine samples were obtained from 250 infertile couples and 250 fertile women as a control. Infertile couples were followed up after 24 months to determine diagnosis, referral for assisted conception, any pregnancy and pregnancy outcome. Data were analysed with regard to the results of (i) serological analysis for specific antibodies to C. trachomatis in serum; (ii) the presence of C. trachomatis and M. genitaliumDNA in first-void urine; and (iii) in a semen sample of the male partner. Prevalence of C. trachomatis in our study population was comparable to other studies using similar methods and test specimens. No evidence of M. genitalium infection was found. Detection of C. trachomatis in one partner rarely correlated with infection in the other. The risk of tubal factor infertility and the probability of pregnancy and pregnancy outcome were unrelated to the results of serological tests for C. trachomatis antibodies or the presence of C. trachomatisDNA in first-void urine of both partners and in a semen sample provided by the male.

Abstract
BACKGROUND AND OBJECTIVES The evidence base supporting the National Chlamydia Screening Programme, initiated in 2003, has been questioned repeatedly, with little consensus on modelling assumptions, parameter values or evidence sources to be used in cost-effectiveness analyses. The purpose of this project was to assemble all available evidence on the prevalence and incidence of Chlamydia trachomatis (CT) in the UK and its sequelae, pelvic inflammatory disease (PID), ectopic pregnancy (EP) and tubal factor infertility (TFI) to review the evidence base in its entirety, assess its consistency and, if possible, arrive at a coherent set of estimates consistent with all the evidence. METHODS Evidence was identified using 'high-yield' strategies. Bayesian Multi-Parameter Evidence Synthesis models were constructed for separate subparts of the clinical and population epidemiology of CT. Where possible, different types of data sources were statistically combined to derive coherent estimates. Where evidence was inconsistent, evidence sources were re-interpreted and new estimates derived on a post-hoc basis. RESULTS An internally coherent set of estimates was generated, consistent with a multifaceted evidence base, fertility surveys and routine UK statistics on PID and EP. Among the key findings were that the risk of PID (symptomatic or asymptomatic) following an untreated CT infection is 17.1% [95% credible interval (CrI) 6% to 29%] and the risk of salpingitis is 7.3% (95% CrI 2.2% to 14.0%). In women aged 16-24 years, screened at annual intervals, at best, 61% (95% CrI 55% to 67%) of CT-related PID and 22% (95% CrI 7% to 43%) of all PID could be directly prevented. For women aged 16-44 years, the proportions of PID, EP and TFI that are attributable to CT are estimated to be 20% (95% CrI 6% to 38%), 4.9% (95% CrI 1.2% to 12%) and 29% (95% CrI 9% to 56%), respectively. The prevalence of TFI in the UK in women at the end of their reproductive lives is 1.1%: this is consistent with all PID carrying a relatively high risk of reproductive damage, whether diagnosed or not. Every 1000 CT infections in women aged 16-44 years, on average, gives rise to approximately 171 episodes of PID and 73 of salpingitis, 2.0 EPs and 5.1 women with TFI at age 44 years. CONCLUSIONS AND RESEARCH RECOMMENDATIONS The study establishes a set of interpretations of the major studies and study designs, under which a coherent set of estimates can be generated. CT is a significant cause of PID and TFI. CT screening is of benefit to the individual, but detection and treatment of incident infection may be more beneficial. Women with lower abdominal pain need better advice on when to seek early medical attention to avoid risk of reproductive damage. The study provides new insights into the reproductive risks of PID and the role of CT. Further research is required on the proportions of PID, EP and TFI attributable to CT to confirm predictions made in this report, and to improve the precision of key estimates. The cost-effectiveness of screening should be re-evaluated using the findings of this report. FUNDING The Medical Research Council grant G0801947.

Abstract
Background. Pelvic inflammatory disease (PID) is a leading cause of both tubal factor infertility and ectopic pregnancy. Chlamydia trachomatis is an important risk factor for PID, but the proportion of PID cases caused by C. trachomatis is unclear. Estimates of this are required to evaluate control measures. Methods. We consider 5 separate methods of estimating age-group-specific population excess fractions (PEFs) of PID due to C. trachomatis, using routine data, surveys, case-control studies, and randomized controlled trials, and apply these to data from the United Kingdom before introduction of the National Chlamydia Screening Programme. Results. As they are informed by randomized comparisons and national exposure and outcome estimates, our preferred estimates of the proportion of PID cases caused by C. trachomatis are 35% (95% credible interval [CrI], 11%–69%) in women aged 16–24 years and 20% (95% CrI, 6%–38%) in women aged 16–44 years in the United Kingdom. There is a fair degree of consistency between adjusted estimates of PEF, but all have wide 95% CrIs. The PEF decreases from 53.5% (95% CrI, 15.6%–100%) in women aged 16–19 years to 11.5% (95% CrI, 3.0%–25.7%) in women aged 35–44 years. Conclusions. The PEFs of PID due to C. trachomatis decline steeply with age by a factor of around 5-fold between younger and older women. Further studies of the etiology of PID in different age groups are required.

Abstract
Mycoplasma genitalium has been recognized as a cause of male urethritis, and there is now evidence suggesting that it causes cervicitis and pelvic inflammatory disease in women. M. genitalium is a slow growing organism, and, with the advent of nucleic acid amplification test (NAAT), more studies are being performed, and knowledge about the pathogenicity of this organism elucidated. With NAAT detection, treatment modalities have been studied, and the next challenge is to determine the most effective antimicrobial therapy. Doxycycline, the first-line antibiotic for urethritis, is largely ineffective in the treatment of M. genitalium and furthermore, resistance to macrolide has also emerged. The most effective drug is Moxifloxacin although there are emerging reports of resistance to it in various parts of the world. This paper not only highlights the current research and knowledge, but also reviews the diversity of health implications on the health of men and women infected with M. genitalium. Alternate antibiotics and the impact of M. genitalium on infertility are areas that require more studies as we continue to research into this microorganism.

Abstract
To determine the association between Mycoplasma genitalium infection and female reproductive tract syndromes through meta-analysis, English-language, peer-reviewed studies were identified via PubMed, Embase, Biosis, Cochrane Library, and reference review. Two reviewers independently extracted data. Random-effects models were employed to calculate summary estimates, between-study heterogeneity was evaluated using I(2) statistics, publication bias was assessed via funnel plots and the Begg and Egger tests, and methodologic quality was rated. Mycoplasma genitalium infection was significantly associated with increased risk of cervicitis (pooled odds ratio [OR], 1.66 [95% confidence interval {CI}, 1.35-2.04]), pelvic inflammatory disease (pooled OR, 2.14 [95% CI, 1.31-3.49]), preterm birth (pooled OR, 1.89 [95% CI, 1.25-2.85]), and spontaneous abortion (pooled OR, 1.82 [95% CI, 1.10-3.03]). Risk of infertility was similarly elevated (pooled OR, 2.43 [95% CI, .93-6.34]). In subanalyses accounting for coinfections, all associations were stronger and statistically significant. Testing of high-risk symptomatic women for M. genitalium may be warranted.

Abstract
BACKGROUND Mycoplasma genitalium is a common sexually transmitted infection associated with human immunodeficiency virus (HIV) infection. Some studies suggest that M. genitalium may increase the risk of HIV acquisition. However, results have been inconsistent, and this association has never been examined longitudinally. METHODS Stored endocervical samples from a longitudinal cohort study of 131 Zimbabwean women in whom HIV-1 seroconversion recently occurred were tested for detection and quantity of M. genitalium using polymerase chain reaction analysis. The associations between M. genitalium and the detection and quantity of genital HIV type 1 (HIV-1) RNA, the detection and quantity of plasma HIV-1 RNA, and the CD4(+) T-cell count was analyzed using mixed-effects regression analysis. RESULTS M. genitalium was detected in 10.5% of stored specimens (44 of 420), and infection persisted for up to 300 days. M. genitalium was independently associated with detection of genital HIV-1 RNA (adjusted odds ratio, 2.67; 95% confidence interval, .99-7.20), after adjustment for plasma viral load, viral set point, CD4(+) T-cell count, herpes simplex virus type 2 detection, and gonorrhea. There was no evidence of an association between M. genitalium detection or quantity and either plasma HIV-1 RNA load or CD4(+) T-cell count. CONCLUSIONS The growing evidence for an association between M. genitalium and HIV genital shedding and the high prevalence and persistence of M. genitalium in this population suggest that further research into this association is important. Consideration of the cost-effectiveness of M. genitalium screening interventions may be warranted.

The prevalence of Mycoplasma genitalium is high in vulnerable populations of women in low-resource settings. However, the epidemiology of infection in these populations is not well established. To determine the prevalence of Mycoplasma genitalium and its association with cervical cytology and other correlates, we recruited 350 female sex workers (FSW) who were 18 to 50 years old in Nairobi, Kenya, for a cross-sectional study. A questionnaire was administered at baseline to obtain information on sociodemographics and sexual behaviors. Women underwent a pelvic exam, during which a physician collected cervical-exfoliation samples for conventional cytology and sexually transmitted infection (STI) testing. Samples were tested for M. genitalium and other STI organisms (Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis) and the E6/E7 mRNA of human papillomavirus (HPV) by Aptima nucleic amplification assays. The prevalence of M. genitalium was 12.9%. FSW who engaged in sexual intercourse during menses were less likely to have M. genitalium infection than those who did not (odds ratio [OR], 0.3; 95% confidence interval [95% CI], 0.1, 0.9). M. genitalium was also less prevalent among FSW who had worked in prostitution for >5 years (6.2%) than among those who had worked for <3 years (17.6%) (OR, 0.3; 95% CI, 0.1, 0.8). FSW who reported more frequent condom use were more likely to be infected with M. genitalium than those who reported less frequent use (OR, 3.8; 95% CI, 1.2, 11.6). These correlates differ from those found in M. genitalium studies conducted with FSW from West Africa and China. Further longitudinal analyses assessing associations with persistent M. genitalium infection are needed.

Abstract
In November 2011, the National Institutes of Health convened a workshop of basic researchers, epidemiologists, and clinical experts in pelvic inflammatory disease to identify research gaps hindering advances in diagnosis, treatment, and prevention. This article summarizes the presentations, discussions, and conclusions of this group and highlights significant controversies that reveal aspects of pelvic inflammatory disease research that would most greatly benefit from the application of newer molecular, immunologic, and radiologic techniques. Multiple limitations to performing new clinical trials exist; however, emerging data from ongoing clinical trials will add to the current body of knowledge regarding prevention and treatment strategies. In addition, use of established health care databases could serve as a valuable tool for performance of unbiased epidemiologic outcome studies.

Abstract
Tragically, genital tract infections are still a major public health problem in many regions. This study was undertaken to determine the prevalence of cervical infection with Herpes simplex virus (HSV), Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) among married women referring to Iranian Hospital, Dubai, UAE. In a retrospective cross-sectional survey, 201 female patients aged 16–80 years who referred to the Obstetrics and Gynecology Department of Iranian Hospital, Dubai, UAE, in 2010 were enrolled. The patients were categorized into three age groups: 15–30 (group I), 31–40 (group II), and ≥41 years old (group III). A cervical swab sample was collected from each woman and the prevalence of cervical infection with HSV, CT, and NG was determined by PCR method. HSV, CT, and NG were detected in 6.5%, 10.4%, and 5.5% of swab samples, respectively. Regarding age, a significant difference was noticed for prevalence of NG and HSV between groups I and III. Because of public health importance of sexual transmitted diseases (STDs), their long-lasting impact on quality of life, and their economic burden, preventing measures and education of women seem necessary.

Abstract
Background: For a long time, infertility has been one of the most sequels in medical sciences with microbial agents as one group of its causes. The possible etiological role of Chlamydia trachomatis in infertility was suggested years ago, but it has not yet been proved completely. To decrease the severe involvements of C. trachomatis infections, screening by efficient diagnostic methods are necessary. Objectives: In this study we attempted to determine the incidence of C. trachomatis in infertile women and compared this with healthy women. Materials and Methods: This case-control study was performed on 150 infertile women with unknown causes and without physiological deficiency for infertility. The control group consisted of 200 fertile safe and impregnated women. Presence of C. trachomatis in the two groups was examined by direct and indirect immunofluorescence tests and PCR. Results: C. trachomatis was detected by direct immunofluorescence method in 23 (15.3%) infertile women compared and 7 (3.5%) healthy controls. Using indirect immunofluorescence tests, a positive test titer of 1:16 as well as the above results were detected in 34 (22.6%) of the infertile cases and 9 (4.5%) of the controls. C. trachomatis was detected by PCR method in 48 (32%) infertile women and 13 (8.7%) among the controls. Conclusions: The results of our study suggest that there is a significant association between C. trachomatis infection and female infertility.

Abstract
Approximately, 15-20% of all cancers worldwide are caused by infectious agents. Understanding the role of infectious agents on cancer development might be useful for developing new approaches to its prevention. Mycoplasma genitalium is a clinically important sexually transmitted pathogen that has been associated with several human diseases. There have been a few studies suggestive of probable roles of Mycoplasma genitalium in cancer development, including prostate and ovarian cancers and lymphomas, but the role of this microorganism like other Mycoplasma species in neoplasia is still conjectural. Considering the prevalence of Mycoplasma genitalium infections and also the emergence of resistant strains, Mycoplasma genitalium needs more attention in the infectious agent cancer-causing research area.

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
BACKGROUND Mycoplasma genitalium (MG) is one of the common causes of non-gonococcal urethritis (NGU) in men and is associated with cervicitis, endometritis, and pelvic inflammatory diseases (PID) in women. The prevalence of MG infection has been reported to be high among female sex workers (FSWs) in many countries, but limited information is known among this population in China. METHODS From July to September 2009, venue-based FSWs were recruited in two cities (Wuzhou and Hezhou) of Guangxi Autonomous Region in southwest China. Information of socio-demographic and behavioral characteristics was collected by a questionnaire-based interview. Cervical specimens were obtained for detection of MG using a real-time polymerase chain reaction (PCR) assay targeting mgpA gene. RESULTS The overall prevalence of MG infection among 810 FSWs was 13.2% (95% CI = 10.87%-15.52%). MG infection was significantly associated with less education (adjusted odds ratio (AOR) = 2.36, 95% CI = 1.15-4.87) consisting of junior high school or below, being single (AOR = 2.27, 95% CI = 1.42-3.62), migrant background (AOR = 2.03, 95% CI = 1.29-3.20), and absence of any STI symptoms in the previous year (AOR = 1.66, 95% CI = 1.09-2.52). CONCLUSIONS MG infection was prevalent among FSWs in the study areas. This pattern of infection suggests that an increasing attention should be paid to MG screening and treatment in this high risk population.

Abstract
OBJECTIVE We sought to analyze the prevalence and clinical manifestations of Mycoplasma genitalium infection in a heterogeneous population of women. STUDY DESIGN The study was designed as a cross-sectional case-control study. Women attending a gynecological outpatient service from 2003 through 2008 were invited to participate. RESULTS The prevalence of M genitalium was 2.1% and of Chlamydia trachomatis was 2.8% among 5519 tested women. A total of 679 women were included. Both pelvic inflammatory disease (PID) and cervicitis were independently associated with M genitalium (odds ratio, 9.00; 95% confidence interval, 1.62-49.89 and odds ratio, 3.80; 95% confidence interval, 2.06-7.03, respectively). Women with C trachomatis had a higher frequency of both PID (18.3% vs 4.9%, P < .001) and cervicitis (33.4% vs 22.3%, P < .001) than women with M genitalium. CONCLUSION M genitalium was an independent and strong risk factor for both cervicitis and PID although, compared to C trachomatis, clinical manifestations were less frequent.

Abstract
Pelvic inflammatory disease (PID), one of the most common infections in non-pregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon clinicians having a high index of suspicion in order to make an early diagnosis and development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms.

Abstract
Mycoplasma genitalium is a sexually transmitted pathogen that is increasingly identified among women with pelvic inflammatory disease (PID). Although Chlamydia trachomatis and Neisseria gonorrhoeae frequently cause PID, up to 70% of cases have an unidentified etiology. This paper summarizes evidence linking M. genitalium to PID and its long-term reproductive sequelae. Several PCR studies have demonstrated that M. genitalium is associated with PID, independent of gonococcal and chlamydial infection. Most have been cross-sectional, although one prospective investigation suggested that M. genitalium was associated with over a thirteenfold risk of endometritis. Further, a nested case-control posttermination study demonstrated a sixfold increased risk of PID among M. genitalium positive patients. Whether or not M. genitalium upper genital tract infection results in long-term reproductive morbidity is unclear, although tubal factor infertility patients have been found to have elevated M. genitalium antibodies. Several lines of evidence suggest that M. genitalium is likely resistant to many frequently used PID treatment regimens. Correspondingly, M. genitalium has been associated with treatment failure following cefoxitin and doxycycline treatment for clinically suspected PID. Collectively, strong evidence suggests that M. genitalium is associated with PID. Further study of M. genitalium upper genital tract infection diagnosis, treatment and long-term sequelae is warranted.

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
BACKGROUND Neisseria gonorrhoeae and Chlamydia trachomatis are characterized by different risk factors, thus control strategies for each also differ. In contrast, risk factors for Mycoplasma genitalium have not been well characterized. METHODS Between 2000 and 2006, 1090 women ages 14 to 45 attending the Public Health-Seattle & King County Sexually Transmitted Diseases Clinic in Seattle, WA, underwent clinical examination and computer-assisted survey interview. M. genitalium was detected by transcription mediated amplification from self-obtained vaginal swab specimens. C. trachomatis and N. gonorrhoeae were detected by culture from cervical swab specimens. RESULTS Prevalent M. genitalium infection was detected in 84 women (7.7%), C. trachomatis in 63 (5.8%), and N. gonorrhoeae in 26 (2.4%). Age <20 and nonwhite race were associated with increased risk for all 3 organisms. In addition, risk for M. genitalium was higher for women with a black partner (adjusted odds ratio [AOR]: 3.4; 95% confidence interval = 1.83-6.29), those never married (AOR: 2.6; 1.08-6.25), using Depo-Provera (AOR: 2.3; 1.19-4.46), and smoking (AOR: 1.7; 1.03-2.83). Drug use, history of STI in the past year, ≤high school education, meeting and having intercourse the same day, anal sex, douching, and hormonal contraception were associated with N. gonorrhoeae or C. trachomatis, but not with M. genitalium. Number of partners was not associated with any of the 3 organisms. CONCLUSIONS The limited number of risk factors for prevalent infection common to all 3 pathogens suggests that M. genitalium may circulate in different sexual networks than N. gonorrhoeae or C. trachomatis. The predominance of sociodemographic risk factors for M. genitalium, rather than high-risk sexual behaviors, suggests broad-based testing may be the most effective control strategy.

Mycoplasma genitalium among young, urban pregnant women. Infect Dis Obstet Gynecol 2010; 2010:984760. [PMID: 20379360 PMCID: PMC2850137 DOI: 10.1155/2010/984760] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2009] [Revised: 02/24/2010] [Accepted: 02/24/2010] [Indexed: 11/17/2022] Open
Abstract
Objective. As the consequences of Mycoplasma genitalium in pregnant women are unknown, we examined the relationship between prenatal M. genitalium infection and SAB.
Methods. The presence of M. genitalium was determined by PCR in urine from 82 women who subsequently experienced a SAB and 134 women who maintained their pregnancies past 22 weeks gestation. The relationships between M. genitalium and subsequent SAB, demographic, current pregnancy, and reproductive health history characteristics were evaluated.
Results. Compared to women without M. genitalium, women with M. genitalium were more likely to report nulliparity (41.7% versus 17.4%, P = .04), history of pelvic inflammatory disease (27.3% versus 8.8%, P = .08), prior C. trachomatis infection (63.6% versus 36.9%, P = .11,) and problems getting pregnant (18.2% versus 4.4%, P = .10). M. genitalium was not associated with SAB (AOR 0.9, 95% CI 0.2–3.8).
Conclusions. Pregnant women who test positive for M. genitalium do not have an increased risk of SAB but report a history of reproductive morbidities.

Abstract
OBJECTIVES The purpose of this study was to investigate the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium, in women attending a sexually transmitted disease (STD) clinic, as well as the frequency of coinfections, and relationship of each organism to cervicitis. METHODS In this cross-sectional study of 324 women attending Baltimore City STD Clinics, C. trachomatis, N. gonorrhoeae, T. vaginalis, and M. genitalium were detected using nucleic acid amplification tests. Demographic characteristics and risk factors were ascertained. RESULTS Overall prevalence of infection with C. trachomatis, N. gonorrhoeae, T. vaginalis, and M. genitalium was found to be 11.1%, 4.6%, 15.3%, and 19.2%, respectively. Prevalence in women with cervicitis was 15.8%, 6%, 18.9%, and 28.6% for C. trachomatis, N. gonorrhoeae, T. vaginalis, and M. genitalium, respectively. Percentages of coinfections were high. C. trachomatis and M. genitalium were significantly associated with cervicitis in univariate analysis, but only M. genitalium was significantly associated with cervicitis (AOR: 2.5) in multiple logistic regression models. CONCLUSION Knowledge of the statistical association of M. genitalium with cervicitis in this study increases the need for further confirmation of the etiologic significance of this organism with cervicitis in more diverse populations. The high prevalence merits more study and may have implications for diagnosis and treatment of cervicitis.

Abstract
BACKGROUND Pelvic inflammatory disease (PID) is one of the most common infections seen in nonpregnant reproductive-age women. It is a major public health problem associated with substantial medical complications (e.g., infertility, ectopic pregnancy, and chronic pelvic pain) and healthcare costs. Prevention of these long-term sequelae requires treatment strategies that are based on the microbiologic etiology of acute PID. OBJECTIVE To determine appropriate antimicrobial regimens for the treatment of acute PID based on published literature. METHODS Clinical trials published since 2002 were assessed conducting a systematic search of the literature on the treatment of acute PID using PubMed (National Library of Congress). The search was limited to articles written in English and published from 1 January 2002 to 30 June 2008. RESULTS Acute PID is a polymicrobic infection caused by both sexually transmitted organisms (primarily Neisseria gonorrhoeae and Chlamydia trachomatis) and microorganisms found in the endogenous flora of the vagina and cervix. The latter include anaerobic bacteria and facultative bacteria, many of which are associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, may also be implicated in the etiology of acute PID. Because of this polymicrobial nature, currently available evidence, as well as recommendations by the CDC, support the use of broad-spectrum regimens (oral or parenteral) that provide adequate coverage against these microorganisms.

Abstract
Chlamydia trachomatis infection can lead to pelvic inflammatory disease, ectopic pregnancy (EP), infertility, and chronic pelvic pain in women. Activins and inducible nitric oxide synthase (iNOS) are produced by the human fallopian tube, and we speculate that tubal activins and iNOS may be involved in the immune response to C. trachomatis in humans and their pathological alteration may result in tubal pathology and the development of EP. Blood and fallopian tubes were collected from 14 women with EP. Sera were analyzed by enzyme-linked immunosorbent assay to detect antibodies against chlamydial heat shock protein 60 (chsp60) and the major outer membrane protein of C. trachomatis. Confirmation of C. trachomatis serology was made using the microimmunofluorescence test. The patients were classified into three groups according to their serological results, and immunohistochemistry and quantitative reverse transcription-PCR were performed to investigate the expression of candidate molecules by tubal epithelial cells among the three groups. This is the first study to show an increase in the expression of activin betaA subunit, type II receptors, follistatin, and iNOS within the human fallopian tube of EP patients who were serologically positive for C. trachomatis. A similar expression profile was observed in the fallopian tubes with detectable antibodies only against chsp60. These results were shown at the mRNA and protein levels. We suggest that tubal activin A, its type II receptors, follistatin, and NO could be involved in the microbial-mediated immune response within the fallopian tube, and their pathological expression may lead to tubal damage and the development of EP.

Abstract
In the UK, many sexually transmitted infections (STIs) are best managed in conjunction with an appropriate specialist, for example, a genitourinary medicine practitioner or a Microbiologist. In most of the world, however, gynaecologists routinely manage STIs in women. This article focuses on the most important infections in women, and those in which management is changing. It also addresses the current status, and new developments around the syndrome of pelvic inflammatory disease (PID), which essentially is an STI.
