Abstract
OBJECTIVE Aim: of our study was to improve the pregravid preparation of women with chronic endometritis to develop individual approaches to overcoming infertility, taking into account the state of endometrium. PATIENTS AND METHODS Materials and Methods: The study included 90 women (main group, n=90), 28 to 38 years with an anatomically normal uterus and chronic endometritis (CE). Patients were divided into 2 groups: group I - 45 women with CE who received conventional treatment; group II - 45 women with CE who received pregravid preparation by subendometrial injections of Platelet-Rich Plasma (PRP). RESULTS Results: At the first stage of study, the ART statistical reports from 2015 to 2022 were analyzed at the Medical Center of Reproductive Health ≪Damia≫, (Ivano-Frankivsk). Analysis of the vaginal flora parameters before treatment at the first stage revealed the presence of conditionally pathogenic flora in culture from the cervical canal (Candida albicans - 2.4%, Escherihia coli - 4.8%, Staphylococcus epidermidis - 6.2% Enterococcus faecalis - 6.9%), and was evidence of a possible recurrence of inflammation during gestation. In the age category, the groups of patients were homogeneous, with no significant differences by the level of AMH and the level of CD 138. Biochemical pregnancy be present in 20 patients (44.4%) of group I and 28 (62.2%) of group II. Fertility within a year after the end of therapy was restored with the proposed method of therapy in most women (51.1%), in the comparison group this number was 11.1% lower. Pregnancy rate between the groups (I and II) did not differ significantly. The number of live births in group II - 19 births (42.2%) - was 2 times higher than I group (9 (20.0%), P<0.05). The most common complication for women in the comparison groups was early pregnancy loss. Among 18 (40.0%) clinical pregnancies of group I, 8 women (17.8%) had early miscarriage, 1 ectopic pregnancy (2.2%), while in group II clinical pregnancy be present in 23 women (51.1%). The number of terminated pregnancies was two times lower than in the first group (8.9% vs. 17.8%, P<0.05). CONCLUSION Conclusions: Chronic endometritis is one of the main causes of pregnancy loss after in vitro fertilization. Patients of the second group were treated with the proposed method of subendometrial injections with Platelet-Rich Plasma (PRP), prepared from autologous blood, is an effective method of preparing the endometrium for embryo transfer and can increase the number of live births in patients with chronic endometritis.

Abstract
The purpose of this systematic review is to identify common hysteroscopic findings suggestive of endometritis, chronic or subclinical, based on current scientific evidence. Data sources were MEDLINE, Embase, PubMed and other sources of grey literature. Four (4) authors independently selected studies addressing hysteroscopic detection of CE based on specific and clearly stated hysteroscopic criteria. The diagnosis was confirmed by histologic assessment, as stated in the materials and methods of these studies included. The initial search identified 599 studies, of which 21 met the inclusion criteria. Significant heterogeneity among published studies on Chronic endometritis (CE) remains the main limitation in performing a metanalysis and further analysis of diagnostic accuracy on the subject. Hysteroscopy is an important diagnostic tool in cases of chronic endometritis when accompanied by endometrial biopsies. Clinicians relate hyperaemia and endometrial oedema with chronic endometritis while more than half include micropolyposis as a pathognomonic feature of this subclinical condition. Micropolyps, stromal oedema, haemorrhagic spots, strawberry aspect, and hyperaemia are proposed as adequate indicators of hysteroscopic evidence of CE according to the literature. The impact of CE in long-term reproductive outcomes remain unclear, thus clinicians ought to communicate this to the patients and provide treatment where clinically appropriate. In addition, we present hysteroscopic images of histologically confirmed CE cases that could play the role of a hysteroscopic atlas.

Abstract
INTRODUCTION Endometritis is the inflammatory condition of the uterus. Citral, a component of lemongrass oil, is known to exhibit anti-inflammatory activity. AIM The effects of citral on LPS-induced endometritis were tested and the mechanisms were investigated. METHODS LPS-induced endometritis mice model was established and the effects of citral were detected using this model. Inflammatory cytokines were tested by ELISA. Ferroptosis was assessed by detecting GSH, ATP, MDA, and Fe2+ levels. Signaling pathway was tested by western blot analysis. RESULTS Citral prevented LPS-induced endometritis through attenuating uterine pathological changes and inflammatory cytokine release. Meanwhile, citral prevents LPS-induced ferroptosis through attenuating MDA and Fe2+ levels, as well as increasing ATP and GSH levels. Furthermore, citral up-regulated Nrf2 and HO-1 expression and attenuated NF-κB activation. In addition, in Nrf2 knockdown mice, the inhibitory roles of citral on ferroptosis and endometritis were largely reversed. CONCLUSION Taken together, citral inhibited LPS-induced endometritis through preventing ferroptosis, which were regulated by Nrf2 signaling pathway.

Abstract
Chronic endometritis (CE) is a local mucosal infectious and inflammatory disorder characterized by unusual filtration of CD138(+) endometrial stromal plasmacytes. CE is attracting attention due to its potential association with infertility of unknown etiology, repeated implantation failure, recurrent pregnancy loss, and several maternal/neonatal complications. Due to the variance in study design among researchers, universal diagnostic criteria remain to be established for the clinical diagnosis and management of CE. This review article aims to summarize current knowledge and provide insights into unsolved questions on CE to establish clinical guidelines for the disease from the viewpoint of human reproduction.

Abstract
Purpose: Chronic endometritis (CE) is an infectious and inflammatory disorder associated with infertility of unknown etiology, repeated implantation failure, and recurrent pregnancy loss. In the current clinical practice, intrauterine interventions such as endometrial biopsy/histopathologic examinations and/or hysteroscopy are required for the diagnosis of CE. In this study, we analyzed the microbiota in vaginal secretions (VS) as a potential prediction tool for CE in infertile women. Methods: Using next-generation sequencing analysis, we compared the VS and endometrial fluid (EF) microbiota in infertile women with (n = 20) or without CE (n = 103). Results: The detection rate of Streptococcus and Enterococcus as well as the bacterial abundance of Atopobium and Bifidobacterium in the VS microbiota was significantly lower in the CE group than in the non-CE group. Meanwhile, the detection rate and bacterial abundance of Lactobacillus in the EF and VS microbiota were at similar levels between the two groups. Conclusion: These findings suggest that VS microbiota in infertile women with CE is characterized by the reduction in Bifidobacterium and lactic-acid-producing bacteria other than Lactobacillus. Our results hold promise for the prediction of CE, not by somewhat interventional intrauterine procedures, but by less invasive VS sampling.

Abstract
The cervicovaginal microbiome plays an important role in protecting women from dysbiosis and infection caused by pathogenic microorganisms. In healthy reproductive-age women the cervicovaginal microbiome is predominantly colonized by protective Lactobacillus spp. The loss of these protective bacteria leads to colonization of the cervicovaginal microenvironment by pathogenic microorganisms resulting in dysbiosis and bacterial vaginosis (BV). Mobiluncus mulieris and Eggerthella sp. are two of the many anaerobes that can contribute to BV, a condition associated with multiple adverse obstetric and gynecological outcomes. M. mulieris has been linked to high Nugent scores (relating to BV morphotypes) and preterm birth (PTB), whilst some bacterial members of the Eggerthellaceae family are highly prevalent in BV, and identified in ~85-95% of cases. The functional impact of M. mulieris and Eggerthella sp. in BV is still poorly understood. To determine the individual immunometabolic contributions of Eggerthella sp. and M. mulieris within the cervicovaginal microenvironment, we utilized our well-characterized human three-dimensional (3-D) cervical epithelial cell model in combination with multiplex immunoassays and global untargeted metabolomics approaches to identify key immune mediators and metabolites related to M. mulieris and Eggerthella sp. infections. We found that infection with M. mulieris significantly elevated multiple proinflammatory markers (IL-6, IL-8, TNF-α and MCP-1) and altered metabolites related to energy metabolism (nicotinamide and succinate) and oxidative stress (cysteinylglycine, cysteinylglycine disulfide and 2-hydroxygluatrate). Eggerthella sp. infection significantly elevated multiple sphingolipids and glycerolipids related to epithelial barrier function, and biogenic amines (putrescine and cadaverine) associated with elevated vaginal pH, vaginal amine odor and vaginal discharge. Our study elucidated that M. mulieris elevated multiple proinflammatory markers relating to PTB and STI acquisition, as well as altered energy metabolism and oxidative stress, whilst Eggerthella sp. upregulated multiple biogenic amines associated with the clinical diagnostic criteria of BV. Future studies are needed to evaluate how these bacteria interact with other BV-associated bacteria within the cervicovaginal microenvironment.

Abstract
Many women with lower genital tract infections associated with sexually transmitted pathogens have evidence of upper genital tract inflammation despite the absence of symptoms and signs traditionally associated with pelvic inflammatory disease (PID). New biomarkers are needed to identify these women with clinically mild PID or subclinical PID (silent salpingitis) to facilitate initiation of early treatment and ameliorate the sequelae associated with upper genital tract infection and inflammation.

Abstract
Pelvic inflammatory disease (PID) is a clinical syndrome that has been associated with a wide range of potential causal pathogens. Three broad groups of organisms have been isolated from the genital tract of people with PID: sexually transmitted organisms such as Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis; bacterial vaginosis (BV)-associated species and genera such as Atopobium vaginae, Sneathia, and Megasphaera; and genera and species usually associated with the gastrointestinal or respiratory tracts such as Bacteroides, Escherichia coli, Streptococcus, or Haemophilus influenza. Although PID is often considered to be synonymous with gonorrhea or chlamydia, these pathogens are found in only one quarter to one third of people with PID, suggesting that broader screening and diagnostic and treatment strategies need to be considered to reduce the burden of PID and its associated sequelae.

Abstract
Genital infections with Chlamydia trachomatis can lead to uterine and oviduct tissue damage in the female reproductive tract. Neutrophils are strongly associated with tissue damage during chlamydial infection, while an adaptive CD4 T cell response is necessary to combat infection. Activation of triggering receptor expressed on myeloid cells-1 (TREM-1) on neutrophils has previously been shown to induce and/or enhance degranulation synergistically with TLR-signaling. Additionally, TREM-1 can promote neutrophil transepithelial migration. In this study, we sought to determine the contribution of TREM-1,3 in immunopathology in the female mouse genital tract during Chlamydia muridarum infection. Relative to control mice, trem1,3-/- mice had no difference in chlamydial burden or duration of lower genital tract infection. We also observed a similar incidence of oviduct hydrosalpinx 45 days post-infection in trem1,3-/- compared to WT mice. However, compared to WT, trem1,3-/- mice developed significantly fewer uterine horn hydrometra. Early in infection, trem1,3-/- mice displayed a notable decrease in the number of uterine glands containing polymorphonuclear cells and uterine horn lumens had fewer neutrophils, with increased G-CSF. Trem1,3-/- mice also had reduced erosion of the luminal epithelium. These data indicate TREM-1,3 contributes to transepithelial neutrophil migration in the uterus and uterine glands, promoting the development of uterine hydrometra in infected mice.

Abstract
Lower genital tract infection and bloodborne spread of infection are the two principal modes for infection of the upper genital tract or for infection of the fetus, neonate or infant. Treponema pallidum and human immunodeficiency virus (HIV) are the two most common bloodborne pathogens that infect the fetus, neonate or infant. Most infections of the upper genital tract, however, spread along epithelial surfaces from the vagina or cervix to the upper genital tract or chorioamnion, fetus, neonate or infant. These infections are caused by either pathogens associated with a dysbiotic vaginal microbiome or those that are sexually transmitted. The clinical syndromes that these pathogens produce in the lower genital tract were discussed in part one of this review. We now discuss the syndromes and pathogens that affect the upper genital tract of both non-pregnant and pregnant women as well as fetus, neonate and infant.

Abstract
Objective: Investigate the relationship between the structure of abdominal wall endometriotic nodules in MRI and their localisation in abdominal wall layers in order to better understand nodule origins. Design: Women who had an MRI prior to surgical treatment of an abdominal wall endometriotic nodule between 2005 and 2016. Population: Thirty-six patients including four patients with two nodules. Methods: MRI images were reviewed. Each nodule was analysed according to its structure (fibrous, cystic, mixed), localisation (subcutaneous fat, intra muscular, intermediary position), and size. Results: Forty nodules were analysed in MRI with no relationship found between localisation and nodule structure ( p = 0.48). 87.5% of mixed nodules were revealed to have a cystic superficial rim extending towards the subcutaneous fat layer. This finding suggests that the glandular part of the nodule is the active part of the disease from which nodule progression occurs. Intermediary and intramuscular nodules were respectively statistically larger than subcutaneous fat nodules indicating a relationship between nodule size and localisation (35 mm (22–53) vs 17 mm (17–23)) ( p = 0.03). Conclusion: Despite differences in environments surrounding the nodules, no significant relationship between nodule structure in imaging and abdominal wall localisation was found. Data from mixed nodules indicate however the possible role of nodule environment on structure and that the mechanism of nodule growth may be linked to development of cystic superficial rims, at the forefront of disease progression, abdominal wall nodules growing from deep to superficial. Studies are required to further investigate our findings and enable greater understanding of the origins of AWE.

Abstract
OBJECTIVE To investigate the therapeutic effect of antibiotic treatment on pregnancy outcomes in the following frozen-thawed embryo transfer cycles of infertile women. DESIGN Retrospective study. SETTING University assisted reproduction unit. PATIENT(S) A total of 640 women were included. Among them, the number of CD138+ cells per high-power field (CD138+/HPF) in the endometrium at the first evaluation was 0 in 88 women; 315 women had 1-4 CD138+/HPF and the remaining 237 had ≥5 CD138+/HPF. Finally, 26 of 237 women had persistent chronic endometritis (PCE) diagnosed. INTERVENTION(S) Hysteroscopy and endometrial biopsy were performed in the proliferative phase. After antibiotic treatment, endometrial biopsy samples were collected again. MAIN OUTCOME MEASURE(S) Live birth rate. RESULT(S) No significant difference in pregnancy outcomes was found between women with CD138+/HPF = 0 and those with CD138+/HPF 1-4. The cure rate was 89.0% in women with CD138+/HPF ≥5 after treatment. The implantation rate (51.6% vs. 32.3%, relative risk [RR] 2.23, 95% confidence interval [CI] 1.07-4.66), clinical pregnancy rate (65.7% vs. 42.3%, RR 2.62, 95% CI 1.17-5.86), live birth rate (52.1% vs. 30.7%, RR 2.45, 95% CI 1.04-5.76), and cumulative live birth rate (64.2% vs. 38.5%, RR 2.88, 95% CI 1.27-6.51) were all significantly higher in women with CD138+/HPF ≤4 than in women with PCE. CONCLUSION(S) CD138+/HPF ≤4 in the endometrium had no negative impact on pregnancy outcomes. Antibiotic treatment was an effective way to improve the reproductive outcomes of women with CD138+/HPF ≥5. PCE was associated with poorer pregnancy outcomes.

[PMID: 33672505 PMCID: PMC7923780 DOI: 10.3390/jcm10040869] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 02/13/2021] [Accepted: 02/15/2021] [Indexed: 02/06/2023] Open
Abstract
Around 1-5% of all couples experience recurrent pregnancy loss (RPL). Established risk factors include anatomical, genetic, endocrine, and hemostatic alterations. With around 50% of idiopathic cases, immunological risk factors are getting into the scientific focus, however international guidelines hardly take them into account. Within this review, the current state of immunological risk factors in RPL in international guidelines of the European Society of Reproduction and Embryology (ESHRE), American Society of Reproductive Medicine (ASRM), German/Austrian/Swiss Society of Obstetrics and Gynecology (DGGG/OEGGG/SGGG) and the Royal College of Obstetricians and Gynecologists (RCOG) are evaluated. Special attention was drawn to recommendations in the guidelines regarding diagnostic factors such as autoantibodies, natural killer cells, regulatory T cells, dendritic cells, plasma cells, and human leukocyte antigen system (HLA)-sharing as well as treatment options such as corticosteroids, intralipids, intravenous immunoglobulins, aspirin and heparin in RPL. Finally, the current state of the art focusing on both diagnostic and therapeutic options was summarized.

Abstract
Chronic endometritis is a pathology often associated with reproductive failure, but there are still no clear recommendations on whether its inclusion in the initial study of infertile couples is necessary. In this discussion paper, based on a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis, the different aspects of the repercussions of chronic endometritis in fertility are evaluated. To avoid possible subjectivity in the analysis and results of this study, the researchers followed the Oxford criteria for the evaluation of evidence. The results from the evaluation of the reviewed literature seem to indicate that, pending new evidence, it would be advisable not to include chronic endometritis in the initial baseline study before assisted reproduction in order not to delay other assisted reproduction treatments. However, it would be advisable in cases of repetitive implantation failure and pregnancy loss after having undergone IVF with viable embryos and before continuing with costly reproductive processes, since results could be improved. The development of randomized studies assessing the impact of antibiotic treatment as a possible therapeutic option in infertile women with chronic endometritis, as well as the possible impact on endometrial microbiota and receptivity/implantation, would allow for the establishment of more precise clinical guidelines in this regard.

Abstract
PROBLEM The definition of chronic endometritis (CE) differs among studies, and currently, there is no accepted consensus. This study aimed to establish the minimum number of immunohistochemical analysis of CD138+ plasma cells to identify a clinically relevant CE. METHOD OF STUDY We performed a retrospective study on 716 infertile patients who never did CE analysis and respective antibiotic treatment before. Samples were obtained by endometrial scratching in the mid-luteal phase before IVF-ET treatment. The number and distribution of CD138+ cells were analyzed by immunohistochemistry. Thirty high-power fields (HPF) were evaluated for each sample. Patients were classified in 2 main groups: (a) CD138low (<5 CD138+ cells in all HPFs), (b) CD138high (≥5 CD138+ cells in at least one HPF). Pregnancy outcome was compared among the groups. RESULTS In the CD138high group, β-hCG positive rate, clinical pregnancy rate and live birth rate were significantly decreased (P = .04, P = .01, P = .04, respectively). Also after adjusting for patient age, body mass index (BMI), and clinical characteristics, the β-hCG positive rate (P = .05), clinical pregnancy rate (P = .01) and live birth rate (P = .02) were significantly lower in the CD138high than those in the CD138low group. Within the CD138low group, these parameters were not significantly different between patients without any plasma cells and patients with up to 4 plasma cells/HPF. CONCLUSION We conclude that immunohistochemical analysis of CD138+ cells is a reliable method to detect CE which can be identified by the presence of ≥5 plasma cells in at least one out of 30 HPF.

Abstract
Background The aim of this study was to determine whether the treatment with doxycycline before and after oocyte retrieval is as effective as salpingectomy in minimizing the detrimental effect of hydrosalpinx on the outcomes of IVF-ET. Methods A retrospective analysis was done for the outcomes of the IVF-ET cycles of patients with hydrosalpinx who underwent laparoscopic salpingectomy prior to IVF cycle (n = 260) or were treated with extended doxycycline treatment during the IVF cycle (n = 45). In doxycycline group, doxycycline (100 mg twice daily) was started 1 week before anticipated oocyte retrieval and was continued for 1 week after oocyte retrieval. In salpingectomy group, the mesosalpinx was coagulated as close as possible to the fallopian tube. Results The implantation, clinical pregnancy, ongoing pregnancy and live birth rates were significantly higher in the salpingectomy group (20.87% Vs. 9.91%, P value =0.007, 44.62% Vs. 20%, P value = 0.002, 39.62% Vs. 17.78%, P value = 0.005 and 37.31% Vs. 15.56%, P value = 0.005 respectively). Conclusion Salpingectomy is more effective than extended doxycycline treatment in improving the outcomes of IVF-ET in patients with hydrosalpinx undergoing IVF-ET. Further, larger well designed randomized controlled trials should be conducted to confirm the findings of this study.

Atherosclerosis 2019; 290:103-110.

Abstract
BACKGROUND AND AIMS Atherosclerosis is a chronic inflammatory disease, and recent studies have shown that infection at remote sites can contribute to the progression of atherosclerosis in hyperlipidemic mouse models. In this report, we tested the hypothesis that genital Chlamydia infection could accelerate the onset and progression of atherosclerosis. METHODS Apolipoprotein E (Apoe-/-) and LDL receptor knockout (Ldlr-/-) mice on a high-fat diet were infected intra-vaginally with Chlamydia muridarum. Atherosclerotic lesions on the aortic sinuses and in the descending aorta were assessed at 8-weeks post-infection. Systemic, macrophage, and vascular site inflammatory responses were assessed and quantified. RESULTS Compared to the uninfected groups, infected Apoe-/- and Ldlr-/- mice developed significantly more atherosclerotic lesions in the aortic sinus and in the descending aorta. Increased lesions were associated with higher circulating levels of serum amyloid A-1, IL-1β, TNF-α, and increased VCAM-1 expression in the aortic sinus, suggesting an association with inflammatory responses observed during C. muridarum infection. Genital infection courses were similar in Apoe-/-, Ldlr-/-, and wild type mice. Further, Apoe-/- mice developed severe uterine pathology with increased dilatations. Apoe-deficiency also augmented cytokine/chemokine response in C. muridarum infected macrophages, suggesting that the difference in macrophage response could have contributed to the genital pathology in Apoe-/- mice. CONCLUSIONS Overall, these studies demonstrate that genital Chlamydia infection exacerbates atherosclerotic lesions in hyperlipidemic mouse and suggest a novel role for Apoe in full recovery of uterine anatomy after chlamydial infection.

Abstract
Standardized terminology has proven benefits in cancer reporting; in contrast, reporting of benign diagnoses in endometrial biopsy currently lacks such standardization. Unification and update on the lexicon can provide the structure and consistency needed for optimal patient care and quality assurance purposes. The Special Interest Group in Gynecologic Pathology of the Canadian Association of Pathologists-Association Canadienne des Pathologistes (CAP-ACP) embarked in an initiative to address the current need for consensus terminology in benign endometrial biopsy pathology reporting. Nine members of the Special Interest Group developed a guideline for structured diagnosis of benign endometrial pathology through critical appraisal of the available peer-reviewed literature and joint discussions. The first version of the document was circulated for feedback to a group of professionals in akin fields, the CAP-ACP Executive Committee and the CAP-ACP general membership. The final 1-page document included 17 diagnostic terms comprising the most common benign endometrial entities, as well as explanatory notes for pathologists. The proposed terminology was implemented in the practice of 5 pathologists from the group, who applied the guideline to all benign endometrial biopsies over a 2-wk period. A total of 212 benign endometrial biopsies were evaluated in this implementation step; the recommended terminology adequately covered the diagnosis in 203 cases (95.8%). A list of terminology for benign endometrial biopsy reporting, based on expert consensus and critical appraisal of the available literature, is presented. On the basis of our results of implementation at multiple centers, the proposed guideline can successfully cover the large majority of diagnostic scenarios. The document has the potential to positively impact patient care, promote quality assurance, and facilitate research initiatives aimed at improving histopathologic assessment of benign endometrium.

Abstract
AIM Chronic endometritis (CE) is a disease of continuous and subtle inflammation characterized by the infiltration of plasma cells in the endometrial stromal area. Although the clinical significance of CE has been thought in clinical practice for a long time because it is either asymptomatic or presents with subtle symptoms, recent studies have shown the potential adverse effects of CE on fertility. In the present review, we focus on the concept, diagnosis, etiology, pathophysiology, diagnosis, impact on reproduction and treatment for it to understand CE. METHODS The published articles were reviewed. RESULTS The prevalence of CE has been found to be 2.8-56.8% in infertile women, 14-67.5% in women with recurrent implantation failure (RIF), and 9.3-67.6% in women with recurrent pregnancy loss. Microorganisms are thought to be a main cause of CE, since antibiotic treatment has been reported to be an effective therapy for CE. Common bacteria are frequently detected in the uterine cavity of CE patients by microbial culture. In CE endometrium, the prevalence of immune cells and decidualization has been reported to be modified, and these modifications are thought to adversely affect fertility. The gold standard for the diagnosis of CE is the histological detection of plasma cells in the stromal area of the endometrium in endometrial specimens, although universally accepted criteria for the diagnosis of CE have not been determined. The treatment currently thought to be most effective for the recovery of fertility in CE is administration of oral antibiotics. Patients whose CE has been cured have been reported to have a higher ongoing pregnancy rate, clinical pregnancy rate, and implantation rate compared with patients with persistent CE. CONCLUSION CE greatly affects implantation and impairs fertility. Antibiotic administration is an effective therapeutic option. Pregnancy rate in in vitro fertilization is improved when CE is cured by antibiotic.

Abstract
Endometritis is subdivided into two categories. Acute endometritis is symptomatic and characterized by microabscess formation and neutrophil invasion in the endometrial superficial epithelium, gland lumina, and uterine cavity. Chronic endometritis is rather silent and recognized as unusual plasmacyte infiltration in the endometrial stromal areas. Over the last decade, studies have disclosed the potential association between poor reproductive outcomes and endometritis, particularly chronic endometritis. The aim of this review is to address the current literature surrounding chronic endometritis and highlight recent advances in the research of this long-neglected gynecologic disease.

Abstract
Background: Acute pelvic inflammatory disease (PID) is a common reason for infertility. This study aimed to evaluate the frequency distribution of endometritis in women with unexplained infertility and comparison with frequency distribution of endometritis in anovulatory infertility to identify the importance of endometritis due to subacute PID evaluation in the case of infertility. Materials and Methods: This case–control study was done on 100 women with unexplained infertility and ovulatory infertility who referred to Shahid Beheshti clinic in 2013 in Isfahan, Iran. They were divided into two groups of unexplained infertility and anovulatory infertility. Endometrial samples were given from all the patients by Pipelle biopsy under sterile conditions, and then prepared samples were sent to the pathology laboratory to evaluate the existence of plasma cells by a pathologist to diagnose endometritis. Results: Frequency distribution of acute PID history among the patients in both groups showed a significant difference (P < 0.05). Prevalence of endometritis in unexplained infertility group was 34% and in anovulatory group was 21% (P < 0.05). Prevalence of vaginitis was 46% in unexplained group and 40% in anovulatory group (P < 0.05), and prevalence of PID was 4% in unexplained infertility group and 0% in anovulatory infertility group. Conclusion: The prevalence of endometritis and vaginitis was more in the unexplained infertility group rather than the anovulatory infertility group that may reveal the importance of endometritis evaluation in the cases of unexplained infertility.

Abstract
Reproduction is vital for producing offspring and preserving genetic resources. However, incidences of many reproductive disorders (e.g. miscarriage, intrauterine growth restriction, premature delivery and lower sperm quality) have either increased dramatically or remained at high rates over the last decades. Mounting evidence shows a strong correlation between enteral protein nutrition and reproduction. Besides serving as major nutrients in the diet, amino acids (AA) are signaling molecules in the regulation of diverse physiological processes, ranging from spermatogenesis to oocyte fertilization and to embryo implantation. Notably, the numbers of bacteria in the intestine exceed the numbers of host cells by 10 times. Microbes in the small-intestinal lumen actively metabolize large amounts of dietary AA and, therefore, affect the entry of AA into the portal circulation for whole-body utilization. Changes in the composition and abundance of AA-metabolizing bacteria in the gut during pregnancy, as well as their translocation to the uterus, may alter uterine function and epigenetic modifications of maternal physiology and metabolism, which are crucial for pregnancy recognition and fetal development. Thus, the presence of the maternal gut microbiota and AA metabolites in the intrauterine environments (e.g. endometrium and placenta) and breast milk is likely a unique signature for the programming of the whole-body microbiome and metabolism in both the fetus and infant. Dietary intervention with functional AA, probiotics and prebiotics to alter the abundance and activity of intestinal bacteria may ameliorate or prevent the development of metabolic syndrome, while improving reproductive performance in both males and females as well as their offspring.

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

Abstract
CONTEXT Chronic endometritis is a condition observed in 3-10% of women with abnormal uterine bleeding (AUB). Diagnosis depends upon the histological detection of plasma cells within the inflammatory infiltrate in the endometrium. Plasma cells on H and E may be obscured by a mononuclear infiltrate, plasmacytoid stromal cells, abundant stromal mitosis, a pronounced predecidual reaction, menstrual features or secondary changes due to exogenous progesterone treatment prior to biopsy. AIMS The objective of this study was to determine utility of syndecan-1 in diagnosis of chronic endometritis in patients with AUB, and to see if any of the secondary histologic features in endometrial biopsy, correlated with the presence of plasma cells on immunohistochemistry (IHC). MATERIALS AND METHODS Fifty endometrial biopsies with a clinical diagnosis of AUB were taken. Endometrium in proliferative phase, secretory phase, endometrial polyps, and disordered proliferative endometrium were studied for the presence of plasma cells. IHC was done using syndecan-1. The secondary histologic features of chronic endometritis like gland architectural irregularity, spindled stroma, stromal edema and hemorrhage with the presence of plasma cells was statistically analysed. Values of P < 0.05 were considered as significant. RESULTS Plasma cells were seen in 11 (69%) of DPE, 8 (66%) of PEB, and 1 (7%) of normal proliferative endometrium and in 2 (40%) of secretory endometrium. Presence of stromal breakdown showed a significant association with plasma cells (P = 0.02) whereas gland architecture irregularity (P = 0.28), stromal edema (P = 0.71) and spindled stromal (P = 0.72) did not show a significant association. CONCLUSIONS Plasma cells were significantly present in AUB patients. Syndecan-1 maybe helpful in unusual cases, where chronic endometritis is suspected as the cause of clinically significant ongoing abnormal bleeding.

Abstract
Study Objective. To identify sensitive and specific histological criteria for endometritis in women with laparoscopically-confirmed acute salpingitis. Methods. Women, age 18–40 years of age presenting with complaints of lower abdominal pain ≤2 weeks and no antibiotics use in past two weeks, were enrolled. They underwent clinical examination, screening for HIV; other sexually transmitted infections plus endometrial biopsy sampling for histopathology. Diagnostic laparoscopy confirmed the diagnosis of acute salpingitis. Controls were women undergoing tubal ligation and HIV-1 infected women asymptomatic for genital tract infection. Results. Of 125 women with laparoscopically-confirmed salpingitis, 38% were HIV-1 seropositive. Nineteen HIV-1 negative controls were recruited. For the diagnosis of endometritis, ≥1 plasma cells (PC) and ≥3 polymorphonuclear lymphocytes (PMN) per HPF in the endometrium had a sensitivity of 74% for HIV-1-seropositive, 63% for HIV-1-seronegative women with a specificity of 75% and positive predictive value of 85% regardless of HIV-1-infection for predicting moderate to severe salpingitis. For HIV-1-seronegative women with mild salpingitis, ≥1 PC and ≥3 PMN had a sensitivity of 16% and a PPV of 57%. Conclusion. Endometrial histology, did not perform well as a surrogate marker for moderate to severe salpingitis, and failed as a surrogate marker for mild salpingitis.

Abstract
The diagnosis of acute pelvic inflammatory disease (PID) is usually based on clinical criteria and can be challenging for even the most astute clinicians. Although diagnostic accuracy is advocated, antibiotic treatment should be instituted if there is a diagnosis of cervicitis or suspicion of acute PID. Currently, no single test or combination of diagnostic indicators have been found to reliably predict PID, and laparoscopy cannot be recommended as a first line tool for PID diagnosis. For this reason, the clinician is left with maintaining a high index of suspicion for the diagnosis as he/she evaluates the lower genital tract for inflammation and the pelvic organs for tenderness in women with genital tract symptoms and a risk for sexually transmitted infection. This approach should minimize treating women without PID with antibiotics and optimize the diagnosis in a practical and cost-effective way.

Abstract
Genital Chlamydia trachomatis infections often result in pelvic inflammatory disease and sequelae including infertility and ectopic pregnancies. In addition to the already established murine models, the development of other animal models is necessary to study the safety and efficacy of prototype vaccine candidates. The intravaginal infection of guinea pigs with C. trachomatis has been tested in three independent studies. The first two studies investigated the effect of hormonal treatment of the animals prior to infection with serovars D and E. The results showed that estradiol treatment was required for sustained infection. The third study conducted an immunization-challenge experiment to explore the feasibility of measuring protection in this guinea pig model. C. trachomatis bacteria were sampled using vaginal swabs and measured by qPCR. Using immunohistochemistry the bacteria were detected in the oviducts 19 days post-infection, indicating that the estradiol treatment resulted in ascending infection. Furthermore, immunization of guinea pigs with live EB formulated with ISCOM matrix led to reduction of cervico-vaginal shedding and diminished the severity of pathology. In this study we have developed a new guinea pig model of C. trachomatis female genital tract infection for the purpose of evaluating potential vaccine candidates.

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

Abstract
Pelvic inflammatory disease (PID) is an infection-caused inflammatory continuum from the cervix to the peritoneal cavity. Most importantly, it is associated with fallopian tube inflammation, which can lead to infertility, ectopic pregnancy, and chronic pelvic pain. The microbial etiology is linked to sexually transmitted microorganisms, including Chlamydia trachomatis, Neisseria gonorrheae, Mycoplasma genitalium, and bacterial vaginosis-associated microorganisms, predominantly anaerobes. Pelvic pain and fever are commonly absent in women with confirmed PID. Clinicians should consider milder symptoms such as abnormal vaginal discharge, metrorrhagia, postcoital bleeding, and urinary frequency as potential symptoms associated with the disease, particularly in women at risk of sexually transmitted infection. The diagnosis of PID is based on the findings of lower genital tract inflammation associated with pelvic organ tenderness. The outpatient treatment of mild-to-moderate PID should include tolerated antibiotic regimens with activity against the commonly isolated microorganisms associated with PID and usually consists of an extended spectrum cephalosporin in conjunction with either doxycycline or azithromycin. Clinically severe PID should prompt hospitalization and imaging to rule out a tuboovarian abscess. Parenteral broad-spectrum antibiotic therapy with activity against a polymicrobial flora, particularly gram-negative aerobes and anaerobes, should be implemented. Screening for and treatment of Chlamydia infection can prevent PID.

Abstract
The mucosal surface of the female genital tract is a complex biosystem, which provides a barrier against the outside world and participates in both innate and acquired immune defense systems. This mucosal compartment has adapted to a dynamic, non-sterile environment challenged by a variety of antigenic/inflammatory stimuli associated with sexual intercourse and endogenous vaginal microbiota. Rapid innate immune defenses against microbial infection usually involve the recognition of invading pathogens by specific pattern-recognition receptors recently attributed to the family of Toll-like receptors (TLRs). TLRs recognize conserved pathogen-associated molecular patterns (PAMPs) synthesized by microorganisms including bacteria, fungi, parasites, and viruses as well as endogenous ligands associated with cell damage. Members of the TLR family, which includes 10 human TLRs identified to date, recognize distinct PAMPs produced by various bacterial, fungal, and viral pathogens. The available literature regarding the innate immune system of the female genital tract during human reproductive processes was reviewed in order to identify studies specifically related to the expression and function of TLRs under normal as well as pathological conditions. Increased understanding of these molecules may provide insight into site-specific immunoregulatory mechanisms in the female reproductive tract.

Abstract
The histopathologic diagnosis of chronic endometritis is based on the presence of plasma cells in the endometrial stroma. However, many conditions can mimic or interfere with the search for plasma cells, including the plasmacytoid stroma cells and predecidual changes of stroma cells. Eosinophils are another type of chronic inflammatory cells, which can be easily identified with routine hematoxylin and eosin stain by their characteristic eosinophilic granules. This study was conducted to investigate whether eosinophils can be used as diagnostic markers of chronic endometritis. The hematoxylin and eosin-stained glass slides of 422 consecutive endometrial biopsies were reviewed. The biopsies that have eosinophils were subjected to immunohistochemical staining with CD138, a marker for plasma cells. In all, 91 of 422 biopsies contained eosinophils with 72.5% (66/91) showing presence of plasma cells (positive staining with CD138). Of these 66 cases, only 4 cases were previously diagnosed as chronic endometritis. These results suggest the presence of eosinophils in endometrial biopsy specimen indicates a need to search for plasma cells (with immunohistochemical stain if needed) for the diagnosis of chronic endometritis.

Abstract
Chlamydia trachomatis (CT) is the most prevalent sexually transmitted bacterial pathogen worldwide and causes severe reproductive tract infections. Currently, nucleic acid amplification tests (NAATs) are the gold standard for clinical diagnosis, but most NAATs are labor intensive and limited to specific CT serovars. We developed and validated a quantitative polymerase chain reaction (qPCR) assay that reproducibly detected CT serovars D, E, F, Ia, and Chlamydia muridarum over a linear range of 2 log(10) to 10 log(10) genomes with low coefficients of variation from both experimental and human urine samples. CT DNA loads from human vaginal, endocervical, and male urethral swabs correlated well with the BD ProbeTec ET assay (Becton Dickinson Diagnostic Systems, Franklin Lakes, NJ) run in parallel. In a preclinical microbicide evaluation, C. muridarum DNA loads in mouse swabs and tissues correlated well with an immunofluorescence assay. The optimized qPCR system provided enhanced sensitivity and facilitated the quantitative evaluation of clinical and experimental preclinical samples for anti-CT therapeutic and microbicide evaluation.

Abstract
PROBLEM The purpose was to identify distinct inflammatory markers in endometrial tissues of women with abnormal uterine bleeding (AUB) and Chlamydia trachomatis infection. METHOD OF STUDY Archived endometrial specimens from 92 randomly selected premenopausal women with AUB were examined for C. trachomatis using the species-specific monoclonal antibody against major outer membrane protein (MOMP) and for histopathology associated with inflammation. Statistical analyses included single and multiple logistic regression. Diagnostic accuracy was summarized using receiver operating characteristic (ROC) curves. RESULTS Chlamydia trachomatis was detected in 44 (48%) of 92 AUB specimens. There were statistically significant correlations of positive MOMP with higher counts of plasma cells (P < 0.01), macrophages (P < 0.0001), and lymphocytic foci (P = 0.01). The ROC curve for macrophages was the strongest predictor (area under the curve = 0.82) for C. trachomatis. CONCLUSION The prevalence of C. trachomatis in women with AUB is under-estimated. Macrophages appear to be a strong marker for the presence of C. trachomatis in the endometrium.

Abstract
Plasma cells are the hallmark of chronic endometritis but are not specific for upper tract infection. Plasma cells have also been noted in hormonally mediated endometrial disorders in association with gland architectural changes ("disordered proliferative" and "anovulatory" patterns), and stromal breakdown. We reviewed benign endometrial biopsies diagnosed at Beth Israel Deaconess Medical Center over a 2-year period described as disordered/anovulatory patterns +/- stromal breakdown. Cases were excluded if tissue was not available; women were younger than 50 years where most diagnoses were atrophic or cancer; or diagnoses were secretory, menstrual endometrium, or polyps. The remaining 61 cases were compared to 33 samples of unremarkable proliferative endometrium. Plasma cells were quantified on hematoxylin and eosin-stained sections and using a histochemical stain methyl green pyronin. The indication for biopsy was an abnormal pattern of bleeding in 34 cases, infertility workup in 7, incidental part of workup for pain, or other findings in 5. The majority of disordered proliferative endometrium had plasma cells (61% grade 1, 17% grade 2) all seen on methyl green pyronin staining only. Two thirds of proliferative endometrium with breakdown showed plasma cells (19% grade 1, 39% grade 2, 10 % grade 3). Plasma cells were rare in inactive endometrium and noted in only 18% of unremarkable proliferative endometrium, all grade 1. Plasma cells are commonly present in the endometrium of women with dysfunctional uterine bleeding and focal stromal breakdown. Given the lack of clinical evidence for infection, the inflammation likely represents a physiologic process.

Abstract
OBJECTIVE The purpose of this study was to determine whether chronic endometritis (CE) that is diagnosed by endometrial biopsy is associated with preterm birth at <37 weeks of gestation. STUDY DESIGN Pathology reports for women aged 18-45 years who underwent clinically indicated endometrial biopsy between 1992 and 2002 were solicited from 3 participating clinical pathology laboratories. Reports were dichotomized into those with and those without CE by a standard definition. Results were linked to birth certificates at the Ohio Department of Health. Women who delivered singleton infants (1992-2002) within 3 years of biopsy were included. Biopsy specimens that were obtained from women with conditions that were associated with indicated preterm birth were excluded. Statistical analysis included logistic regression, Student's t-test, Fisher's exact test, and chi-square test, where appropriate. A probability value of <.05 was considered significant. RESULTS The 1603 endometrial biopsy reports were identified and forwarded. The Ohio Department of Health linked birth certificate data to 193 reports, 157 of which met inclusion criteria and comprised the study group. Twenty-six of 157 women (16.6%) who were studied had CE. The odds of delivering at <37 weeks of gestation were not significantly higher for women with CE (odds ratio, 2.51; 95% CI, 0.86-7.29; P = .091). Infants who were born at <37 weeks of gestation were more likely to be black (P < .001); to have intrapartum fever, meconium, or fetal distress (P = .026) and to require assisted ventilation (P = .016). CONCLUSION In our study group, women with CE were not more likely to deliver an infant at <37 weeks of gestation.

Abstract
Innate immunity in the endometrium has fundamental significance for reproduction. Although toll-like receptors (TLRs) play central roles in innate immune responses, their expression in the human endometrium remains to be fully elucidated. We have examined the gene expression of TLR2, TLR3, TLR4, and TLR9 in endometrial tissues by real-time quantitative PCR and in situ hybridization. The expression levels of the four genes in endometrial tissues varied in a similar pattern during the menstrual cycle; the levels were high in the perimenstrual period and low in the periovulatory period. Expression of the four genes was detected in both epithelial cells and stromal cells throughout the menstrual cycle. Expression levels were higher in epithelial cells for TLR3 and in stromal cells for TLR4, while they were comparable in epithelial cells and stromal cells for TLR2 and TLR9. These findings imply that differential spatio-temporal expression patterns of TLRs subserve proper innate immunity of the endometrium.

Abstract
The purpose of the present study was to evaluate pigs as a large-animal model for female genital infection with two Chlamydia trachomatis human serovar E strains. Sixteen-week-old specific-pathogen-free female pigs (gilts) were intravaginally infected with the trachoma type E reference strain Bour or the urogenital serovar E strain 468. Several conclusions can be drawn from our findings on the pathogenicity of a primary C. trachomatis genital infection in gilts. First of all, we demonstrated that the serovar E strains Bour and 468 could ascend in the genital tract of gilts. The serovar E strains could replicate in the superficial columnar cervical epithelium and in the superficial epithelial layer of the uterus, which are known to be the specific target sites for a C. trachomatis genital infection in women. Second, inflammation and pathology occurred at the replication sites. Third, the organisms could trigger a humoral immune response, as demonstrated by the presence of immunoglobulin M (IgM), IgG, and IgA in both serum and genital secretion samples. Our findings imply that the pig model might be useful for studying the pathology, pathogenesis, and immune response to a C. trachomatis infection of the genital system.

Abstract
Production of reactive oxygen species in unfractionated peripheral blood increased in parturient women without postpartum infectious complications and patients with postpartum endometritis. The control group included nonpregnant women with normal reproductive function. Intergroup differences were revealed in the degree of respiratory burst activation with opsonized zymosan and response of isolated granulocytes to chemotactic peptide N-formyl-Met-Leu-Phen (1 muM). Production of reactive oxygen species tended to normal after therapy. We studied the effects of a specific mitogen-activated protein kinase p38MAPK inhibitor and inhibitors of tyrosine protein phosphatases and phosphatidylinositol-3-kinase. The role of p38MAPK in reactive oxygen species generation by cells changes significantly in parturient women.

Abstract
OBJECTIVE The objective of this study was to compare the demographic, clinical, and microbiologic findings in women with subclinical pelvic inflammatory disease (PID) and women with acute PID. STUDY A cross-sectional study was performed using cohorts from 2 separate studies of 1293 women at risk for PID. Most participants were recruited from emergency departments, sexually transmitted disease clinics, and family planning clinics in metropolitan centers. We compared demographic, clinical, and microbiologic findings among women with acute PID, women with subclinical PID, and women without endometritis (controls). Statistical analyses included chi-square for categorical variables, calculation of odds ratio and 95% confidence intervals, and polychotomous logistic regression when appropriate. RESULTS Similar proportions of women with acute and subclinical PID tested positive for cervical Chlamydia trachomatis (odds ratio [OR], 1.1; 95% confidence interval, 0.6-2.0) and had bacterial vaginosis (OR, 0.7; 95% CI, 0.2-1.8). The rate of cervical Neisseria gonorrhoeae infection in women with subclinical PID was intermediate between the rates in women with acute PID and controls (21% vs. 49% vs. 7%, respectively, P <0.001, test for trend). Endometrial recovery of N. gonorrhoeae and C. trachomatis in women with subclinical PID was also seen at intermediate levels. Similar distributions of teenagers, women who smoked or used illicit drugs, and women engaging in sexual intercourse during menses were found in each group. Proportions of women with subclinical PID who were black and with lower education levels were intermediate between the proportions of these characteristics in women with acute PID and controls. CONCLUSION Demographic and microbiologic characteristics of women with subclinical and acute PID are comparable. These findings suggest that the pathophysiological mechanisms of acute and subclinical PID are similar.

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
OBJECTIVE Our purpose was to evaluate the antimicrobial therapy effect on clinical and laboratory findings among women at risk for endometritis. STUDY DESIGN A prospective antimicrobial treatment trial of 153 women was performed to characterize subacute endometritis and to determine the treatment effect on endometritis resolution. RESULTS After antimicrobial treatment, significant reductions occurred in abnormal bleeding (60% vs 29%), mucopurulent cervicitis (20% vs 6%), uterine tenderness (20% vs 6%), and histologic endometritis (38% vs 4%), all P<.001. In women with prior pelvic inflammatory disease (PID), endometritis was present in 43% with and 28% without current Chlamydia trachomatis or Neisseria gonorrhoeae. In women without prior PID, endometritis was present in 23% with and 12% without current C trachomatis or N gonorrhoeae (P=.002 for trend). CONCLUSIONS In women without a clinical diagnosis of PID, antimicrobial therapy decreased abnormal clinical findings and histologic endometritis. Prior PID is additive with current cervical infection as a risk for endometritis.
