Abstract
Pelvic inflammatory disease (PID) is an infection of the female upper genital tract that is typically polymicrobial with classic core involvement of Neisseria gonorrhoeae and/or Chlamydia trachomatis, though other endogenous flora from the vagino-cervical areas can be involved as well. It is often a sexually transmitted disease but other etiologic routes are also noted. A variety of risk factors have been identified including adolescence, young adulthood, adolescent cervical ectropion, multiple sexual partners, immature immune system, history of previous PID, risky contraceptive practices and others. An early diagnosis and prompt treatment are necessary to reduce risks of PID complications such as chronic pelvic pain, ectopic pregnancy and infertility. Current management principles of PID are also reviewed. It is important for clinicians to screen sexually active females for common sexually transmitted infections such as Chlamydia trachomatis and provide safer sex education to their adolescent and young adult patients. Clinicians should provide comprehensive management to persons with PID and utilize established guidelines such as those from the US Centers for Disease Control and Prevention (CDC).

Abstract
Background. Group B Streptococcus is an organism that commonly infects a wide range of hosts including infants in the first week of life, pregnant women, and older age adults as well as adults with underlying medical comorbidities. Case. Large pelvic abscess in a nonpregnant patient found to be caused by Group B Streptococcus was treated successfully with IR guided drainage and antibiotics. Conclusion. Though rare, GBS can still be a cause of invasive infection even in individuals who are nonpregnant and have no underlying comorbidities. Empiric antibiotic coverage for this organism should be kept in mind when treating an abscess.

Abstract
Pelvic inflammatory disease (PID) has been investigated in Western countries and identified to be associated with chronic pelvic pain and inflammation. Bladder pain syndrome/interstitial cystitis (BPS/IC) is a complex syndrome that is significantly more prevalent in women than in men. Chronic pelvic pain is a main symptom of BPS/IC, and chronic inflammation is a major etiology of BPS/IC. This study aimed to investigate the correlation between BPS/IC and PID using a population-based dataset.We constructed a case-control study from the Taiwan National Health Insurance program. The case cohort comprised 449 patients with BPS/IC, and 1796 randomly selected subjects (about 1:4 matching) were used as controls. A Multivariate logistic regression model was constructed to estimate the association between BPS/IC and PID.Of the 2245 sampled subjects, a significant difference was observed in the prevalence of PID between BPS/IC cases and controls (41.7% vs 15.4%, P < 0.001). Multivariate logistic regression analysis revealed that the odds ratio (OR) for PID among cases was 3.69 (95% confidence interval [CI]: 2.89-4.71). Furthermore, the ORs for PID among BPS/IC cases were 4.52 (95% CI: 2.55-8.01), 4.31 (95% CI: 2.91-6.38), 3.00 (95% CI: 1.82-4.94), and 5.35 (95% CI: 1.88-15.20) in the <35, 35-49, 50-64, and >65 years age groups, respectively, after adjusting for geographic region, irritable bowel syndrome, and hypertension. Joint effect was also noted, specifically when patients had both PID and irritable bowel disease with OR of 10.5 (95% CI: 4.88-22.50).This study demonstrated a correlation between PID and BPS/IC. Clinicians treating women with PID should be alert to BPS/IC-related symptoms in the population.

Abstract
In humans, the vaginal microbiota is thought to be the first line of defense again pathogens including Chlamydia trachomatis. The guinea pig has been extensively used as a model to study chlamydial infection because it shares anatomical and physiological similarities with humans, such as a squamous vaginal epithelium as well as some of the long-term outcomes caused by chlamydial infection. In this study, we aimed to evaluate the guinea pig-C. caviae model of genital infection as a surrogate for studying the role of the vaginal microbiota in the early steps of C. trachomatis infection in humans. We used culture-independent molecular methods to characterize the relative and absolute abundance of bacterial phylotypes in the guinea pig vaginal microbiota in animals non-infected, mock-infected or infected by C. caviae. We showed that the guinea pig and human vaginal microbiotas are of different bacterial composition and abundance. Chlamydia caviae infection had a profound effect on the absolute abundance of bacterial phylotypes but not on the composition of the guinea pig vaginal microbiota. Our findings compromise the validity of the guinea pig-C. caviae model to study the role of the vaginal microbiota during the early steps of sexually transmitted infection. The vaginal microbiota of the guinea pig differs from that of humans and cannot prevent chlamydial infections efficiently.

Abstract
PURPOSE OF REVIEW The present review considers recent pelvic inflammatory disease literature. It remains a difficult condition to accurately diagnose and manage in the adolescent woman. Failure of accurate diagnosis and prompt management leads to complications, including chronic pelvic pain and infertility. RECENT FINDINGS Annual chlamydia screening of sexually active adolescents is an important method for early identification of this common cause of this disorder. Youth with positive screens can be lost for treatment if effective follow-up plans are not in place in clinical practice. The intrauterine device is not a risk factor for this condition in adolescents and is a recommended contraceptive device in sexually active adolescent women. A variety of chlamydial antigens are being used to help differentiate lower genital infection from upper genital disorder. Clinicians are not following established protocols for its diagnosis and management. SUMMARY Sequelae can be reduced in adolescent women if clinicians continue with regular chlamydia screening in sexually active adolescent women, have a low index of suspicion for pelvic inflammatory disease, carefully follow accepted treatment protocols, and teach youth comprehensive sexuality education including regular condom use. Funded research is needed to develop improved diagnosis and management tools as well as a chlamydia vaccine.

Abstract
BACKGROUND Repeated genital infections with Chlamydia trachomatis are common and associated with serious adverse reproductive sequelae in women such as infertility, ectopic pregnancy, and chronic pelvic pain. Retesting for repeat chlamydial infection is recommended 3 months after treatment for an initial infection; however, retesting rates in various settings are low. In order to design interventions to increase retesting rates, understanding provider barriers and practices around retesting is crucial. Therefore, in this survey of family planning providers we sought to describe: (1) knowledge about retesting for chlamydia; (2) attitudes and barriers toward retesting; (3) practices currently utilized to ensure retesting, and predictors associated with their use. METHODS We conducted a cross-sectional, self-administered, Internet-based survey of a convenience sample of family planning providers in California inquiring about strategies utilized to ensure retesting in their practice setting. High-intensity strategies included chart flagging, tickler (reminder) systems, follow-up appointments, and phone/mail reminders. RESULTS Of 268 respondents, 82% of providers reported at least 1 barrier to retesting, and only 44% utilized high-intensity interventions to ensure that patients returned. Predictors associated with use of high-intensity interventions included existence of clinic-level retesting policies (OR 3.95, 95% CI 1.98-7.88), and perception of a high/moderate level of clinic priority toward retesting (OR 3.75, 95% CI 2.12-.6.63). CONCLUSION Emphasizing the importance of retesting to providers through adoption of clinic policies will likely be an important component of a multimodal strategy to ensure that patients are retested and that provider/clinic staff take advantage of opportunities to retest patients. Innovative approaches such as home-based retesting with self-collected vaginal swabs and use of cost-effective technologies to generate patient reminders should also be considered.

Abstract
C. TRACHOMATIS (CT) infections of the upper genital tract in women are either acute, sub acute or chronic. CT infection has a tendency to be chronic, latent and persistent as a consequence of the host immune reaction to CT major outer membrane protein, 57 Kd heat shock protein and lipopolysaccharide. Chlamydial persistence can be induced as a result of inflammatory and/or immune regulated cytokines, Interferon gamma depletion of tryptophan causes a stress response involving development of abnormal forms with increased levels of stress response proteins which maintain host immune responses with continuous fibrin exudate.The main clinical consequences are acute and chronic pelvic inflammatory disease, with infertility, ectopic pregnancy and, less frequently, chronic pelvic pain as late sequelae.PID, WHEN ACUTE, IS MARKED BY BILATERAL PELVIC PAIN, PLUS OTHER INFECTIOUS SIGNS IN TYPICAL CASES: fever, leucorrhea, red and purulent cervix. In 50% cases, infectious signs are slight or absent or there is an atypical clinical situation. Laparoscopy is the key for diagnosis. It allows the surgeon to have a direct look at the pelvic organs and perform microbiologic and histologic sampling. In severe cases, laparoscopy allows the surgeon to aspirate the purulent discharge and successfully treat pelvic abscesses.Chronic PID usually is clinically silent. It is in most cases discovered some years after the onset of CT infection, in women operated on for tubal infertility or ectopic pregnancy. Further studies, to evaluate treatments efficiency in chronic cases and factors leading to ectopic pregnancy or to recurrence, are indicated.

Abstract
Chlamydia trachomatis (CT) is the most common bacterial cause of sexually transmitted infections. CT infections are strongly associated with risk-taking behavior. Recommendations for testing have been implemented in many countries. The effectiveness of the screening programs has been questioned since chlamydia rates have increased. However, the complication rates including pelvic inflammatory disease, tubal factor infertility, and tubal pregnancy have been decreasing, which is good news. The complication rates associated with CT infection have clearly been over-estimated. Genetic predisposition and host immune response play important roles in the pathogenesis of long-term complications. CT plays a co-factor role in the development of cervical neoplasia caused by high-risk human papillomavirus (HPV) types. The evidence linking CT and other adverse pregnancy outcomes is weak. The current nucleic acid amplification tests perform well. A new genetic variant of CT was discovered in Sweden but has only rarely been detected elsewhere. Single-dose azithromycin remains effective against CT. Secondary prevention by screening is still the most important intervention to limit the adverse effects of CT on reproductive health.

Abstract
Pelvic inflammatory disease (PID) is one of the most common serious infections of nonpregnant women of reproductive age. Management of PID is directed at containment of infection. Goals of therapy include the resolution of clinical symptoms and signs, the eradication of pathogens from the genital tract and the prevention of sequelae including infertility, ectopic pregnancy and chronic pelvic pain. The choice of an antibiotic regimen used to treat PID relies upon the appreciation of the polymicrobial etiology of this ascending infection including Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium and other lower genital tract endogenous anaerobic and facultative bacteria, many of which are associated with bacterial vaginosis. Currently available evidence and the CDC treatment recommendations support the use of broad-spectrum antibiotic regimens that adequately cover the above named microorganisms. The outpatient treatment of mild-to-moderate PID should include tolerated antibiotic regimens consisting of an extended-spectrum cephalosporin in conjunction with either azithromycin or doxycycline. Clinically severe PID should prompt hospitalization and imaging to rule out a tubo-ovarian abscess. Parenteral broad-spectrum antibiotic therapy with activity against a polymicrobial flora, particularly Gram-negative aerobes and anaerobes, should be implemented.

Abstract
OBJECTIVE To determine the presence of M. genitalium and C. trachomatis in women attending fertility clinics and to follow these women for the effects of previous infections or tubal damage on pregnancy rate and outcome. DESIGN Prospective study. SETTING Fertility clinics and university. PATIENT(S) Two hundred twelve couples attending fertility clinics. INTERVENTION(S) Blood and cervical swab samples from the women. Tubal status was assessed by culdoscopy and/or laparoscopy. MAIN OUTCOME MEASURE(S) Presence of M. genitalium and C. trachomatis was determined by polymerase chain reaction. Serum samples were tested for antibodies against M. genitalium and C. trachomatis. RESULT(S) One swap sample was positive to C. trachomatis and none positive to M. genitalium. Thirty of the 194 women had tubal factor infertility (TFI); 23% and 17% of women with TFI had antibodies to C. trachomatis and M. genitalium, respectively, compared with 15% and 4%, respectively, of women with normal tubes; 36% and 14% of women with a self-reported history of pelvic inflammatory disease (PID) were seropositive to C. trachomatis and M. genitalium, respectively, compared with 10% and 6%, respectively, of women without past PID. CONCLUSION(S) A strong antibody response against M. genitalium or C. trachomatis but no sign of current or chronic infection was found in women with TFI, indicating that previous infections caused by these microorganisms may have resulted in permanent damage and occlusion of the fallopian tubes.

Abstract
OBJECTIVES Mycoplasma genitalium has been associated with cervicitis, endometritis, and tubal factor infertility. Because the ability of this bacterium to ascend and infect the fallopian tube remains undefined, we performed an investigation to determine the prevalence of M genitalium in fallopian tube, endometrial, and cervical specimens from women laparoscopically diagnosed with acute salpingitis in Nairobi, Kenya. METHODS Women presenting with pelvic inflammatory disease were laparoscopically diagnosed with salpingitis. Infection with M genitalium in genital specimens was determined by polymerase chain reaction (PCR). RESULTS Of 123 subjects with acute salpingitis, M genitalium was detected by PCR in the cervix and/or endometrium in nine (7%) participants, and in a single fallopian tube specimen. In addition, those infected with M genitalium were more often HIV infected than women not infected by M genitalium (seven of nine (78%) v 42 of 114 (37%), p<0.03). CONCLUSIONS M genitalium is able to ascend into the fallopian tube, but its association with tubal pathology requires further investigation.

Abstract
BACKGROUND Subclinical pelvic inflammatory disease (PID) is a common condition among women with lower genital tract infection and is believed to be responsible for a greater proportion of PID-related sequelae than acute PID. Subclinical PID is diagnosed histologically after endometrial biopsy. In the literature, many different histologic criteria have been used to define subclinical PID. GOAL To determine if endometrial plasma cells are commonly found in women at low likelihood of PID. STUDY A cross-sectional study of 33 women undergoing tubal ligation and at low likelihood of PID was performed. At the time of tubal ligation, study participants underwent visualization of pelvic organs and an endometrial biopsy, which was analyzed for the presence of neutrophils and plasma cells. Demographic, clinical, and microbiologic data were compared among women with and without endometrial plasma cells. RESULTS Endometrial plasma cells were identified in one third (33%) of the asymptomatic, fertile, healthy women in our cohort. The presence of plasma cells was not associated with lower genital tract infection, including bacterial vaginosis. Laparoscopic evidence of fallopian tube damage was similar in patients with and without endometrial plasma cells (22% in each group). CONCLUSION Plasma cells are commonly found in the endometria of healthy women and may not represent upper genital tract inflammation.

Abstract
Screening women for lower genital tract infection with Chlamydia trachomatis is important in the prevention of pelvic inflammatory disease, ectopic pregnancy and infertility. This systematic review aims to state clearly which of the available diagnostic tests for the detection of C. trachomatis would be most effective in terms of clinical effectiveness. The review included all studies published from 1990 onward that evaluated diagnostic tests in asymptomatic, young, sexually active populations. Medline and Embase were searched electronically and key journals were hand-searched. Further studies were identified through the Internet and contact with experts in the field. All studies were reviewed by two reviewers and were scored by Irwig's assessment criteria. Additional quality assessment criteria included a documented sexual history and recording of previous chlamydial infection. The reviews were subjected to meta-analysis and meta-regression. The 30 studies that were included examined three types of DNA-based test--ligase chain reaction (LCR), PCR and gene probe--as well as enzyme immuno-assay (EIA). The results showed that while specificities were high, sensitivities varied widely across the tests and were also dependent on the specimen tested. Pooled sensitivities for LCR, PCR, gene probe and EIA on urine were 96.5%, 85.6%, 92% and 38%, respectively, while on cervical swabs the corresponding sensitivities of PCR, gene probe and EIA were 88.6%, 84% and 65%. Meta-analysis demonstrated that DNA amplification techniques performed best for both urine and swabs in low prevalence populations. We conclude that nucleic acid amplification tests used on non-invasive samples such as urine are more effective at detecting asymptomatic chlamydial infection than conventional tests, but there are few data to relate a positive result with clinical outcome.

Abstract
Chlamydia trachomatis is one of the causes of acute and chronic urinary tract infections and acute or silent salpingitis. Chronic or recurrent female urinary or genital tract infections with Chlamydia trachomatis have been recognised as a significant factor in the development of acute or chronic renal interstitial inflammation or increased risk of ectopic pregnancy. In most cases Chlamydia trachomatis is sexually transmitted. Moreover, it is one of the most common sexually transmitted pathogens. The current estimate is that in the United States there occur 4.5 million new infections each year. We describe 3 cases of recurrent urinary tract infections due to Chlamydia trachomatis.

Abstract
The present communication considers possibilities of how to improve surveillance programs for sexually transmitted infections and some conditions not yet included among the 'established' sexually transmitted infections. An extended list of sexually transmitted infection agents is proposed for monitoring and a syndrome-based surveillance program for what and when to screen pregnant women is discussed. Problems of how to deal with recurrences in chronic sexually transmitted infections are discussed. The value of concomitant surveillance programs, for clinicians and laboratories, is stressed. The importance of reporting the method(s) used to establish the diagnosis, as well as the circumstances under which the sampling was made, for example at screening, is also highlighted.

Abstract
OBJECTIVES To analyse trends in rates of genital chlamydial infection and ectopic pregnancy between 1985 and 1995 in a county in Sweden. SETTING Uppsala county where screening for chlamydial infection, treatment, and contact tracing has been widespread and where ectopic pregnancies are recorded. METHODS Rates of chlamydial infections and ectopic pregnancy between 1985 and 1995 were calculated for women aged 20-39 years. Poisson and linear regression were used to examine the association between the risk of ectopic pregnancy and the current rates of chlamydial infection and rates of chlamydial infection from up to 5 years earlier. MAIN OUTCOME MEASURES Rates of chlamydial infection per 100 examinations, rates of ectopic pregnancy per 1000 pregnancies, rate ratios and 95% confidence intervals for an increase in chlamydial infections of 5 new cases per 100 examinations. RESULTS 103 870 cervical samples from women aged 15-39 years were analysed; 5648 (5.4%) were positive for chlamydia. 51 630 pregnancies were analysed; 930 (1.8%) were ectopic. Both rates declined over time. For women aged 20-24 years there was a strong correlation between the rate of ectopic pregnancy and the rate of chlamydial infection in the same year (r=0.93, P<0. 001); among older women correlations were stronger with rates of chlamydial infection occurring 1 or 2 years earlier. In Poisson regression ectopic pregnancy was most strongly associated with the current rate of chlamydial infection among women aged 20-24 (rate ratio 1.85, 95% confidence interval 1.44 to 2.38), with the rate of infection 1 year earlier among 25-29 year olds (rate ratio 1.72, 1. 33 to 2.22) and 30-34 year olds (rate ratio 2.27, 1.53 to 3.37); and with the rate 2 years earlier among 35 to 39 year olds (rate ratio 2. 58, 1.45 to 4.60). CONCLUSIONS Declining rates of genital chlamydial infections have probably led to a fall in the rate of ectopic pregnancies. The timing of the decline in the rate of ectopic pregnancies varies with age. Among young women falling rates of chlamydial infection have been accompanied by an immediate reduction in the rate of ectopic pregnancy.

Abstract
BACKGROUND Upper genital tract chlamydial infections in women are on the increase, and serology might be a convenient tool for diagnosis. Evaluations of this approach are needed in women with or without microbiologic evidence of organisms in the upper genital tract. GOALS To compare the results of antibody assays with cervical culture and upper genital tract histopathology in women with pelvic pain and chlamydial plasmid DNA in endometrial biopsies. STUDY DESIGN Chlamydia trachomatis plasmid DNA was detected by polymerase chain reaction (PCR) on extracted deparaffinized endometrial biopsy tissue. Five antichlamydial antibody assays were performed measuring total antibodies or immunoglobulin G (IgG), IgM, and IgA classes on sera from 14 women with plasmid DNA as well as 31 without plasmid DNA. RESULTS Accepting the presence of plasmid DNA as the gold standard, no single test had total diagnostic accuracy. The best sensitivity and specificity occurred with the following assays: whole inclusion fluorescence (WIF) (100% and 80.6%); microimmunofluorescence IgM (MIF IgM) (78.6% and 93.6%); and heatshock protein-60 enzyme immunoassay (42.9% and 100%). Although recombinant anti-lipopolysaccharide enzyme-linked immunosorbent assays measured anti-chlamydial antibodies in a large proportion of these women, specificity was low. The sensitivity and specificity of cervical culture was 28.6% and 100% and of endometrial histopathology was 71.4% and 48.4%. Analysis of patient serological profiles suggested that and 6 women without plasmid DNA may have been cases that were missed by PCR. CONCLUSIONS Evaluations of assays to diagnosis Chlamydia trachomatis upper genital tract infections could use the presence of organisms or their markers in the upper genital tract as a standard of comparison. Some of these serological assays, such as WIF or MIF IgM, may be helpful in diagnosis, but more studies are needed.

Abstract
OBJECTIVES To examine the accuracy of a commercial polymerase chain reaction (PCR) test (Amplicor CTR, Roche Diagnostic Systems, Branchburg NJ) for identification of endocervical chlamydial infections through both laboratory evaluation and among a diverse teaching hospital patient population. METHODS Testing of reliable threshold inocula and reproducibility were carried out using laboratory stock organisms. Paired endocervical samples from patients with a wide range of indications were tested by PCR and an established culture procedure, and discrepant pairs were further analyzed to determine true results. RESULTS Laboratory evaluation suggested that one copy of target DNA from a viable organism consistently yielded a positive result, and test reproducibility was very good, with an overall coefficient of variation of 15%. Compared to true results in 1,588 paired clinical samples from 1,489 women with a 10% prevalence of infection, the PCR test and culture yielded respective sensitivities of 87.4% and 78.0%, and negative predictive values of 98.6% and 97.6%. Specificity and positive predictive value for both tests were 100%. Cost per specimen was nearly identical at $18.84 and $18.88 respectively. Polymerase inhibitors and organisms lacking target DNA were not found in false-negative PCR samples. CONCLUSION This commercial PCR test is accurate, cost-competitive, and much faster than culture for diagnosis of endocervical chlamydia infections in our population of intermediate prevalence of chlamydial infection.

Abstract
Chlamydia trachomatis is a frequent sexually transmitted disease. The diagnosis of C. trachomatis infection by cytology is controversial. We compared the ability of Papanicolaou (Pap) smears to detect C. trachomatis infection with antigen detection (enzyme immunoassay; EIA) and polymerase chain reaction (PCR). One hundred sixty-seven women attending a therapeutic abortion clinic were enrolled in the study. Endocervical samples were first collected for EIA and PCR, and then Pap smears were prepared for cytologic evaluation. Eight patients were excluded from the study due to the lack of an endocervical component. The criteria established by Gupta and associates (Diagn Cytopathol 1988;4:224-229; Acta Cytol 1979;23:315-320) were used in this study to assess the specificity and sensitivity of the Pap smear in recognizing C. trachomatis infection. After EIA testing, the remaining sample was subjected to phenol-chloroform extraction to purify the DNA and then tested by PCR. Positive PCR samples were subjected to repeat phenol-chloroform and retested to confirm the positive result. Using a confirmed PCR or a blocked EIA as the extended gold standard, the incidence of C. trachomatis infection was 9.4%. Fifteen of the 159 cases reviewed were positive by extended gold standard. Thirteen (86.7%) of those 15 cases were interpreted as negative by cytology (false-negatives), and two (13.3%) cases were positive. Of the remaining 144 cases, 14 cases (9.7%) were interpreted as positive by cytology (false-positives) but were not confirmed by the extended gold standard. Ten (66.7%) of the 15 cases confirmed by the extended gold standard were interpreted as negative by EIA (false-negatives), and five (33.3%) were positive. There were no false-positives by EIA. In this study, the sensitivity and the specificity for cytology were 13.3% and 90.3%, respectively. The positive predictive value was 12.5%, and the negative predictive value for cytology was 90.9%. The sensitivity and the specificity for EIA were 33.3% and 100%, respectively. The positive predictive value was 100%, and the negative predictive value for EIA was 93.5%. Both EIA and cytology are insensitive methods compared with PCR. Based on these data, cytology should not be used to diagnose C. trachomatis infection in an asymptomatic female population with a moderate risk of C. trachomatis infection.

Abstract
In order to analyze the protective role that IgA may play in a chlamydial infection two IgA monoclonal antibodies (mAb), MoPn 4-2 and MoPn 13-2, were raised against the major outer membrane protein (MOMP) of the Chlamydia trachomatis mouse pneumonitis (MoPn) biovar. mAb MoPn 4-2 was found to be serovar specific while mAb MoPn 13-2 was species specific. mAb MoPn 4-2 recognized a surface exposed conformational epitope as shown by its ability to bind to native EBs and nonreduced MOMP while failing to bind to heat and trypsin treated EBs, to reduced MOMP and to synthetic MOMP peptides. In contrast, mAb MoPn 13-2 recognized a nonconformational epitope since it was able to bind treated EBs, to reduced MOMP and to the synthetic peptide MTTWNPTISGSGI located in variable domain 4 of the MOMP. Both mAbs agglutinated intact EBs and had in vitro neutralizing activity. However, mAb MoPn 4-2 had a 20-fold higher in vitro neutralizing ability when compared to mAb MoPn 13-2 (50% neutralization at 5 micrograms ml-1 vs 100 micrograms ml-1). In an in vitro in vivo infectivity assay, mAb MoPn 4-2 protected mice against infertility when C. trachomatis MoPn elementary bodies were preincubated with the mAb before inoculation. In addition, passive transfer of mAb MoPn 4-2 resulted in significant protection as measured by a decrease in the number of mice infected, and in the intensity and duration of vaginal shedding. These results support previous findings suggesting that IgA antibodies can play a role in protection against a chlamydial infection, and further encourage work to develop vaccination strategies that elicit mucosal immunity.

Abstract
In an attempt to use an expanded "gold standard" in an evaluation of an antigen detection test for Chlamydia trachomatis, the AMPLICOR (Roche Diagnostics Systems, Inc., Branchburg, N.J.) PCR Chlamydia trachomatis test and culture were used with 591 sets of cervical specimens. Of the 591 specimens assayed, 35 were retested due to either an equivocal result by the PCR (19 samples) or a discrepancy between the results of culture, PCR, and the antigen detection method. During the repeat testing of the samples with equivocal and discrepant results, all but one interpretation change was due to the PCR result. In addition, upon repeat testing the PCR assay value measured in optical density units varied widely for 13 of these specimens. These 13 specimens were then tested in triplicate by the manufacturer with primers to the chlamydia plasmid and in duplicate with primers to the major outer membrane protein. Only 3 of the 13 specimens gave the same interpretation with these five replicates. In summary, reproducibility problems with the AMPLICOR test should be considered before it is incorporated as part of routine testing or used as an expanded gold standard for chlamydia testing.

Abstract
OBJECTIVE Our purpose was to compare the rate of adverse pregnancy outcome in pregnant mice with lower genital tract chlamydial infection who had a prior short chlamydial infection versus a prior long-term infection. STUDY DESIGN A total of 127 female mice were divided into short-term and long-term infection groups. We infected the lower genital tracts with Chlamydia trachomatis. After 7 days in the short-term infection group and 30 days in the long-term infection group, we treated the mice with tetracycline-impregnated chow. After documentation of cure, the mice were mated and transvaginally reinfected with Chlamydia trachomatis. Forty-one of the 127 (32%) mice became pregnant. We noted the number of mice with fetal death and the number of pups present. We cultured the lower uterine segment and the pups for Chlamydia. RESULTS Seven of 21 (33%) mice in the short-term infection group had fetal deaths compared with 1 of 20 (5%) in the long-term infection group (p < 0.05). In the short-term infection group 21 of 21 (100%) mice had positive transvaginal chlamydial cultures after reinoculation compared with only 7 of 20 (35%) in the long-term infection group (p < 0.000004). Seventeen of 21 (81 %) mice in the short-term infection group had positive chlamydial cultures from the lower uterine segment versus 1 of 20 (5%) in the long-term infection group (p < 0.000001). Sixty-five percent of pups in the short-term infection group and none (0%) of the pups in the long-term infection group were positive for Chlamydia (p < 0.00001). CONCLUSIONS We conclude that in this murine model a prior 30-day genital tract infection with Chlamydia protects pregnant mice from subsequent reinfection and adverse pregnancy outcomes.

Abstract
BACKGROUND AND OBJECTIVES Acute pelvic inflammatory disease (PID) affects women in their reproductive years and is often a complication of a sexually transmitted disease (STD), particularly Neisseria gonorrhoeae and Chlamydia trachomatis. Infertility, ectopic pregnancy, and chronic lower abdominal pain are common long-term sequelae to acute PID. Through different preventive measures, endemic N. gonorrhoeae is almost eliminated, and C. trachomatis has been reduced almost fourfold in Sweden. GOALS To investigate variations in STD-associated acute PID and the extent to which this influenced the yearly incidences of patients hospitalized for this complication during a 25-year-period. STUDY DESIGN Hospital records of 2499 patients admitted and treated for acute PID from January 1, 1970 to December 31, 1994 were analyzed for infection with N. gonorrhoeae. Routine laboratory diagnosis for C. trachomatis infection started June 1, 1980. Detailed statistical analysis for chlamydial-associated PID in this study, therefore, covers the period January 1, 1981 to December 31, 1994 and includes 1030 patients. RESULTS Gonorrhea occurred in 42% of patients with acute PID in 1970 and decreased continuously to zero in 1988 and beyond. Concomitant urogenital chlamydial infection reduced almost fourfold from 28.4% in 1985 to 7.7% in 1994. Yearly admissions for acute PID fluctuated slightly (< or = 16%) in the early 1970s and early 1980s but increased greatly (> 60%) in the middle and late 1970s; the highest was 180 per year in 1976. This coincided with high incidence rates of gonorrhea in the general population, and probably of genital C. trachomatis infection as well, coupled with an increased use of intrauterine contraceptive device in nulliparous women. The largest increase in admissions for acute PID was in the 15- to 29-year-old group. A steady decrease started in 1987 and reached the low figure of 26 admissions in 1994. The greatest decrease occurred in the 15- to 19-year-old group, from the relative age distribution of 28.9% in the period 1970 to 1974 to 12.9% in 1990 to 1994. Yearly admissions for the > or = 35-year-old group remained almost constant during the study period, but the relative age distribution shifted from second lowest (excluding those 14 years or younger, totaling 15 admissions for the entire study period), 9.1% at the beginning of the study period, to the second largest, 24.9% at the end of it. The study also showed that the total and relative rates of recurrence decreased. CONCLUSIONS Measures aimed at reducing incidences of gonorrhea and genital chlamydial infection will reduce the incidences of one of the most serious complications of these STDs, acute PID, and, in turn, its long-term sequelae.

Abstract
AIMS To examine the role of Chlamydia trachomatis in ectopic pregnancy by detection of DNA in archival salpingectomy specimens, and in their preceding cervical specimens and endometrial biopsies, by using the polymerase chain reaction (PCR). METHODS Archival paraffin embedded salpingectomy tissues (n = 48) from 37 women with ectopic pregnancy were examined for the presence of C trachomatis plasmid and omp1 DNA by PCR. In addition, preceding cervical specimens (n = 58) stored either as cervical cell suspensions or as archival cervical smears, and preceding endometrial biopsies (n = 18), taken 0-5.8 years before the ectopic pregnancy, were examined by PCR for the presence of C trachomatis. RESULTS C trachomatis DNA was detected in only one of the 48 salpingectomy specimens from 37 women. However, in six of the 37 women, C trachomatis DNA was detected in the genital specimens (cervix and/or endometrial) taken before salpingectomy. C trachomatis infections were mostly found in endometrial or cervical specimens taken more than three years before ectopic pregnancy. No chlamydial DNA was found in endometrial or cervical specimens taken at the same time of the ectopic pregnancy. CONCLUSIONS Although no C trachomatis DNA was found in salpingectomy specimens, several women with ectopic pregnancy had C trachomatis infections in endometrial and cervical specimens in the past. This suggests that at least in these cases the ectopic pregnancy is a late post-inflammatory complication of an ascending C trachomatis infection resulting in a scarred fallopian tube.

Abstract
OBJECTIVE The detection of acute phase antibodies against C trachomatis and its comparison with tissue culture or polymerase chain reaction (PCR) on samples of cervix and urethra obtained from patients with pelvic inflammatory disease (PID). METHODS In the academic hospital Dijkzigt, Rotterdam, The Netherlands, prospective investigations were performed on 49 consecutive patients who were admitted with the diagnosis of PID. Infections with C trachomatis were traced using tissue culture, PCR or by determining acute phase IgG and IgM antibodies. Differences between the sensitivities of serology and tissue culture or PCR were calculated using the Fisher exact test. RESULTS C trachomatis infection was detected more often in PID patients using serology in comparison with PCR (p < 0.05) or tissue culture (p < 0.05). All patients who were positive in tissue culture also had acute phase antibodies. CONCLUSION The establishing of acute C trachomatis infections in PID patients on the basis of serology was superior to either tissue culture or PCR on samples obtained from cervix and urethra.

Abstract
OBJECTIVE To determine if serologic data and, more particularly, antichlamydial immunoglobulin (Ig) M can be used for diagnosis of current chlamydial intrapelvic gynecologic infection. DESIGN Forty-two women with acute salpingitis (group A), 131 women with tubal factor infertility (group B), and 98 pregnant women (control group C) were studied. SETTING Hôpital Jean Rostand, Sèvres (patients), Laboratories Magenta and Eylau, Paris (serology), Institut Pasteur, Paris (cultures). INTERVENTIONS Study groups: endocervical/urethral swabs, pelvic samples; serologic study before and after treatment. CONTROL GROUP Serologic study. MAIN OUTCOME MEASURES Serum samples were collected from each patient initially and 6 to 9 weeks later; additionally, two to five sequential sera were obtained from 22 (group A) and 25 (group B) patients with positive cultures, evolutive serology, or positive antichlamydial IgM. Sera were tested for antichlamydial IgG by a microimmunofluorescence assay using Chlamydia trachomatis elementary bodies and for IgA and IgM by whole inclusion-fluorescent assay. RESULTS Before treatment, there was a correlation between the presence of antichlamydial IgM and positive cervical and/or intrapelvic chlamydia cultures. After treatment, antichlamydial IgM, when initially positive, rapidly disappeared in most subjects; its persistence after 4 months was significantly associated with tubal sequelae in group A patients and persistence of positive intrapelvic chlamydial cultures in group B women. CONCLUSION Serologic analysis of women with acute salpingitis or tubal infertility, including antichlamydial IgM, may aid both in the before treatment diagnosis of chlamydial infection and in the follow-up evaluation.

Abstract
OBJECTIVE Our objective was to study the relationship between the presence of Chlamydia trachomatis antibodies and the success of IVF treatment. DESIGN We evaluated 118 in vitro fertilization and embryo transfer (IVF-ET) treatment cycles from 51 couples with a history of infertility lasting for at least 2 years. All women starting a treatment cycle had their serum chlamydial antibody titers measured by indirect immunofluorescent technique. All patients received similar ovarian stimulation regimens and the oocytes collected were inseminated with similar concentrations of motile sperm. Clinical data from couples where the female partner had C. trachomatis ab titers > or = 40 have been compared with the equivalent data from couples where the female partner had C. trachomatis ab titers < 40. RESULTS There was no statistically significant difference between the two groups concerning age, infertility period, oocytes collected, oocytes fertilized, and fertilization rate, and the pregnancy rates were comparable. CONCLUSION Previous exposure to C. trachomatis did not alter the success rate of IVF-ET.

Abstract
OBJECTIVES To determine the prevalence of humoral IgG antibodies to Chlamydia trachomatis in women with tubal pregnancies. METHODS A study was made of 49 women with tubal pregnancies. The control group consisted of 50 pregnant women without any known fertility problems. RESULTS Compared with the pregnant group of women, a statistically significant higher prevalence of chlamydial IgG antibody titer > or = 64 was observed among the patients with gross abnormalities in the fallopian tube contralateral to the ectopic gestation (P = 0.002). The differences in geometric mean titer (GMT) were also statistically significant (P = 0.0004) between those two groups. The recall frequency of past pelvic inflammatory disease (PID) was increased 5-6-fold in patients with ectopic pregnancy, compared with the intrauterine pregnant women. Twenty-five of 30 patients (83%) with ectopic pregnancy and macroscopic tubal sequelae recalled a history of PID. The prevalence of chlamydial IgG antibody titer > or = 64 among women with a past history of PID was 75.6% (34/45), compared with 44.4% (24/54) among the women without any history of past PID history (P = 0.002). Concerning GMT, the numbers were 27 and 154 among women with and without a past history of PID, respectively (Fig. 2). CONCLUSIONS These findings suggest that C. trachomatis is a major cause of oviductal damage, which predisposes to ectopic pregnancy.

Abstract
The incidence of positive Chlamydia cultures in females undergoing laparoscopy for tubal patency is high. We advocate routine screening for Chlamydia infection in females with infertility. Of seventy-five patients undergoing laparoscopy for infertility, 49 grew Chlamydia on tissue culture of material from the cervix, an incidence of 65.3%. of these 49 cases, 33 (67.3%) had tubal blockage. In asymptomatic patients, 22 out of 50 had positive cultures from the cervix, an incidence of 44%. Peritoneal fluid culture was negative in all infertile patients. When compared to populations studied elsewhere, the incidence of Chlamydia appears to be high in our population and significantly higher in the infertile patients. In the management of infertility, pelvic inflammatory disease, and neonatal conjunctivitis, Chlamydia should be routinely investigated and treated.

Abstract
The following are the conclusions that can be derived from a review of the literature regarding the role of infection in the aetiology of male infertility. (i) Temporary inflammatory episodes in the male reproductive tract which are self-limiting are probably common. (ii) Caution should be exercised in the use of leukospermia or bacteriospermia as parameters for glandular infection. (iii) There is a need for alternative techniques for detecting non-symptomatic deep pelvic infections in the male; one technique of great promise is rectal ultrasound. (iv) Rectal ultrasound indicates that a large number of men with poor sperm quality have a non-symptomatic, chronic prostatovesiculitis. (v) Increasing evidence implicates Chlamydia trachomatis as being a major cause of chronic non-bacterial prostatitis. (vi) An important aspect of chlamydial infections in men may be that the male accessory sex glands may function as reservoirs for the organism, increasing the probability of infection in the female. (vii) Ureaplasma urealyticum may also play an important aetiological role in male infertility but its significance is confounded by its acknowledged function as a commensal in the reproductive tract. (viii) One of the manifestations of male reproductive tract infection is the induction of sperm autoantibodies. (ix) There is a need for more systematic controlled studies of the effects of antibiotic treatment on sperm quality with different preparations for extended periods using patient groups in which a glandular infection has been verified, e.g. by rectal ultrasonography.

Abstract
This study investigates the prevalence of antichlamydial antibodies in infertile women, who underwent diagnostic laparoscopy. The patients were divided into two groups based on the presence or absence of damage of the fallopian tubes. Antichlamydial IgG antibodies were found in 22 of 27 (81.5%) infertile women with damaged fallopian tubes and 10 of 23 (43.5%) women with normal tubes. Mean geometric IgG titres for C. trachomatis were significantly higher in the patients with damaged tubes (187.4 vs. 39.39). C. trachomatis was not isolated from the peritoneal fluids. Only two chlamydial cultures of cervical specimens were positive, one in each group. These findings confirm that C. trachomatis may be a major cause of tubal damage with resultant infertility.

Abstract
A newly developed microwell enzyme immunosorbent assay (EIA) system by Syva Company (Palo Alto, CA) can detect Chlamydia trachomatis in < 3 hr. It uses a polyclonal antibody to chlamydial lipopolysaccharide and end points are determined with a spectrophotometer. Three clinical trial sites (University of California Medical Center, San Francisco, CA; University of Washington, Seattle, WA; and Louisiana State University Medical Center, New Orleans, LA), compared this EIA with tissue culture (TC) for identifying Chlamydia in urogenital specimens. Overall prevalence by TC was 10.4% (136 of 1306). When tests were compared with TC (using vials or microtiter plates and a fluorescent antibody stain), we found an EIA sensitivity of 93.4% (127 of 136) and a specificity of 98.1% (1148 of 1170). This EIA has a performance profile that is, at the very least, comparable with other nonculture methods for diagnosing genital tract infections with C. trachomatis.

Abstract
Several studies have shown that previous chlamydial genital infection, reflected by serological markers, is strongly associated with tubal damage leading to tubal infertility. In 105 women undergoing laparoscopy, multiple samples were collected from the lower (urethra and cervix) and upper (endometrium, peritoneal fluid, tubal lumen) genital tract, in order to isolate Chlamydia trachomatis in cell culture. Chlamydia trachomatis was isolated from at least one site in 13 (30.9%) of 42 infertile women with tubal infertility, in 5 (12.1%) of 41 women with unexplained infertility, in 1 of 4 women affected by acute salpingitis and in 1 (5.5%) of 18 women with endometriosis or uterine malformations. The latter group was the control group. Thirteen (65%) of the 20 positive women harboured Chlamydia trachomatis in their upper genital tract alone and 16 women were positive in one or both tubes. Only one of the positive women showed laparoscopic signs of acute pelvic infection. Four of the 5 positive women with unexplained infertility harboured Chlamydia trachomatis in the tubal lumen. This study confirms that chlamydial infection is strongly associated with tubal damage. It suggests that cervical cultures are inadequate for excluding a tubal infection and that chlamydial colonization of the tubal mucosa is possible in the absence of symptoms and laparoscopic signs of active infection.

Abstract
OBJECTIVE To measure the prevalence of chlamydial genital infection in Ethiopian women attending gynaecological, obstetric and family planning clinics; to identify the epidemiological, social and economic factors affecting the prevalence of infection in a country where routine laboratory culture and serological tests for chlamydial species are unavailable; to determine the risk factors for genital chlamydial infection in those with serological evidence of other sexually transmitted diseases. SUBJECTS 1846 Ethiopian women, outpatient attenders at two teaching hospitals and a mother and child health centre in Addis Ababa, Ethiopia. SETTING Gynaecological outpatient department, antenatal, postnatal and family planning clinics. METHODS Sera were tested for type-specific anti-chlamydial antibodies using purified chlamydial antigens (C. trachomatis A-C (CTA-C), C. trachomatis D-K (CTD-K), Lymphogranuloma venereum (LGV1-3), and C. pneumoniae (CPn)), in a micro-immunofluorescence test. The genital chlamydia seropositivity was analysed against patient's age, clinic attended, ethnic group, religion, origin of residence, age at first marriage and first coitus, income, number of sexual partners, duration of sexual activity, marital status/profession, obstetric and contraceptive history, and seropositivity for other sexually transmitted diseases. RESULTS Overall exposure to chlamydia species was found in 84%, genital chlamydial infection in 62%, and titres suggestive of recent or present genital infection in 42% of those studied. Genital chlamydial infection was highest (64%) in family planning and lowest (54%) in antenatal clinic attenders. Exposure to genital chlamydia species was influenced by ethnic group and religion. Those married and sexually active under 13 years of age had greater exposure (69%) to genital chlamydial infection than those first sexually active aged over 18 (46%). Prevalence of infection was highest in those with more than five sexual partners (78%) and in bargirls (84%). The lowest income groups had a higher prevalence (65%) of genital chlamydial infection than the wealthiest (48%). Multivariate analysis showed the most important factors to be age at first coitus, religion, prostitution and present age of the woman in that order. Risk for genital chlamydial infection was increased in those with seropositivity for syphilis, gonorrhoea, HSV-2 but not HBV infection. CONCLUSION/APPLICATION: Chlamydial genital infections are highly prevalent in both symptomatic and asymptomatic Ethiopian women. The high prevalence of infection reported reflects a complexity of socioeconomic factors: very early age at first marriage and first coitus, instability of first marriage, subsequent divorce and remarriage or drift into prostitution, all of which are influenced by ethnic group, religion and poverty--together with transmission from an infected group of prostitutes by promiscuous males to their wives, lack of diagnostic facilities and inadequate treatment of both symptomatic and asymptomatic men and women. The problem of chlamydial disease in Ethiopia needs to be addressed urgently in the context of control of STD.

Abstract
Serum antichlamydial antibodies were studied in three groups. Group A included 49 women with recent ectopic pregnancy, group B included 56 women with normal first trimester pregnancy, and group C included 20 women with a first episode of acute salpingitis. In the ectopic pregnancy group, a significantly higher percentage of women had IgG antichlamydial antibodies than in the normal pregnancy group (75.5% vs. 46.4%, P less than 0.001). Women with acute salpingitis had the same prevalence of IgG antibodies as patients who had an ectopic pregnancy (60% vs. 75.5%, P less than 0.10). In the ectopic pregnancy group, the women had a significantly higher geometric mean titer (GMT) of antichlamydial IgG antibodies than women with an intra-uterine pregnancy (70.4% vs. 27.3%, P less than 0.001). The results suggest that there is a positive relation between prior Chlamydia trachomatis infection and risk for tubal pregnancy.
