Suppression of Chlamydial Pathogenicity by Nonspecific CD8+ T Lymphocytes.

Chlamydia trachomatis, a leading infectious cause of tubal infertility, induces upper genital tract pathology, such as hydrosalpinx, which can be modeled with Chlamydia muridarum infection in mice. Following C. muridarum inoculation, wild-type mice develop robust hydrosalpinx, but OT1 mice fail to do so because their T cell receptors are engineered to recognize a single ovalbumin epitope (OVA457-462). These observations have demonstrated a critical role of Chlamydia-specific T cells in chlamydial pathogenicity. In the current study, we have also found that OT1 mice can actively inhibit chlamydial pathogenicity. First, depletion of CD8+ T cells from OT1 mice led to the induction of significant hydrosalpinx by Chlamydia, indicating that CD8+ T cells are necessary to inhibit chlamydial pathogenicity. Second, adoptive transfer of CD8+ T cells from OT1 mice to CD8 knockout mice significantly reduced chlamydial induction of hydrosalpinx, demonstrating that OT1 CD8+ T cells are sufficient for attenuating chlamydial pathogenicity in CD8 knockout mice. Finally, CD8+ T cells from OT1 mice also significantly inhibited hydrosalpinx development in wild-type mice following an intravaginal inoculation with Chlamydia Since T cells in OT1 mice are engineered to recognize only the OVA457-462 epitope, the above observations have demonstrated a chlamydial antigen-independent immune mechanism for regulating chlamydial pathogenicity. Further characterization of this mechanism may provide information for developing strategies to reduce infertility-causing pathology induced by infections.

Effectiveness and Adverse Events of Early Laparoscopic Therapy versus Conservative Treatment for Tubo-Ovarian or Pelvic Abscess: A Single-Center Retrospective Cohort Study.

BACKGROUND/AIM: We aimed to assess the value of early laparoscopic therapy in management of tubo-ovarian abscess (TOA) or pelvic abscess. METHODS: This was a retrospective study of all consecutive patients who were initially diagnosed with TOA or pelvic abscess at the local hospital between January 2010 and December 2014. The risks of operation and recurrence were analyzed using logistic analyses. RESULTS: The durations of body temperature > 38.0°C (p = 0.001) and hospitalization (p < 0.001) were longer in the conventional group versus the early laparoscopy group. In the conventional group, 15 (50%) patients finally underwent laparoscopic exploration. The abscess size in the late laparoscopic group was significantly larger than the successful antibiotic treatment group (6.3 ± 1.5 vs. 4.9 ± 1.2 cm, p = 0.010). Abscess > 5.5 cm was independently associated with antibiotic failure (OR 4.571; 95% CI 1.612-12.962). Compared with late laparoscopy, early laparoscopy was associated with a shorter operation time (p = 0.037), less blood loss (p = 0.035), and shorter durations of body temperature > 38.0°C (p < 0.001) and hospitalization (p < 0.001). The cost was the lowest in the patients successfully treated conservatively. CONCLUSION: Early laparoscopic treatment is associated with shorter time of fever resolution, shorter hospitalization, and less blood loss compared with conventional treatment for TOA or pelvic abscess.

Therapeutic influence of intraperitoneal injection of Wharton's jelly-derived mesenchymal stem cells on oviduct function and fertility in rats with acute and chronic salpingitis.

To study the effect of Wharton's jelly-derived mesenchymal stem cells (WJMSCs) on the rat salpingitis model, 50 female Wistar rats were randomly divided into one control and five model groups. Mixed bacteria were injected into the oviducts of model groups. The treated acute and chronic groups received intraperitoneal injections of WJMSCs (1 x 10(6)) once a week for three weeks. Serum inflammation factor, collagen fiber content and oviduct-specific glycoprotein (OVGP) levels were detected in control, chronic, ex-treatment acute and chronic, and treated acute and chronic groups (N = 5 for each group). Pregnancy rate and litter size of control, chronic, treated acute and treated chronic groups were compared. Serum TNF-α and INF-γ levels increased in ex-treatment acute and chronic groups, and restored to normal in the acute treated group but not in the treated chronic group. Oviduct collagen fibers did not increase significantly before or after treatment in the acute group, but it increased in the ex-treatment chronic group and did not improve after treatment. After treatment, OVGP levels restored to normal in the acute group but reduced in the ex-treatment and treated chronic groups and chronic group. The pregnancy rate and litter size of the treated acute group recovered to normal, but in the treated chronic group and chronic model group, they decreased significantly. Thus, intraperitoneal injection of WJMSCs could recover the function of the oviduct in acute salpingitis rats, but its effect on chronic salpingitis was poor. Timely treatment of salpingitis is crucial to preserve reproductive function.

Chrono- and Immunocorrection of Inflammatory Disorders of Internal Reproductive Organs in Women of Reproductive Age.

We compared the effectiveness of immunomodulators used in the treatment of patients with chronic salpingitis and oophoritis with or without changes in succinate dehydrogenase (SDH) activity in blood lymphocytes at incubation with the drug. Diurnal variations in individual reaction of SDH in blood lymphocytes to thymalin or ridostin were revealed. In the groups of women receiving ridostin or thymalin during the reaction of lymphocyte SDH to it, improvement of clinical laboratory and immunological parameters was observed in the majority of the patients and no effect was found in a lesser group of patients than in the groups treated with drugs during the absence of lymphocyte SDH reaction thereto. The timing of the presence of SDH reaction to drugs in the immunocompetent cells makes it possible to set the optimal daily regime of their application and to select a drug that would be most effective in each particular case.

Effect of ultrasound-guided aspiration of hydrosalpingeal fluid during oocyte retrieval on the outcomes of in vitro fertilisation-embryo transfer: a randomised controlled trial (NCT01040351).

OBJECTIVE: To determine whether the ultrasound-guided aspiration of hydrosalpingeal fluid at the time of oocyte retrieval can improve the outcomes of in vitro fertilisation-embryo transfer (IVF-ET). PATIENTS: One hundred and ten women with ultrasound-visible hydrosalpinges were randomised to two groups based on computer generated randomisation list. Fifty-four women underwent ultrasound-guided aspiration of hydrosalpingeal fluid prior to IVF-ET and 53 women underwent IVF-ET without any prior intervention. RESULTS: Patients who underwent aspiration of hydrosalpinges demonstrated a significantly increased implantation, clinical pregnancy rates. Among the patients in the aspiration group, the implantation rate and pregnancy rates were higher in the subgroup of patients with no reaccumulation of hydrosalpingeal fluid within the first 2 weeks after aspiration compared to patients with reaccumulation of hydrosalpingeal fluid within the first 2 weeks after aspiration, but this difference failed to reach statistical significance. Furthermore, no pregnancies occurred in the four patients with uterine fluid collection detected during IVF-ET cycles. CONCLUSION: The aspiration of hydrosalpingeal fluid at the time of oocyte retrieval is simple, safe and effective procedure for treatment of patients with ultrasound-visible hydrosalpinges particularly those without rapid reaccumulation of hydrosalpingeal fluid after aspiration or uterine fluid collection during the IVF-ET cycles.

Efficacy and safety evaluation of acupuncture therapy for patients with salpingitis in IVF-ET: A protocol of systematic review and meta-analysis.

BACKGROUND: As an alternative for salpingitis in IVF-ET, acupuncture has gradually attracted the attention of clinicians based on the theory of syndrome differentiation and treatment of Chinese traditional medicine. However, due to the lack of evidence-based medical evidence, the author designed the program to evaluate the effectiveness and safety of acupuncture. METHODS: From the beginning to August 2020, 7 electronic databases will be searched. Two of our researchers will independently conduct research selection, data extraction, and risk assessment of bias. We will use Review Manager 5.3 software for meta-analysis and heterogeneity assessment. In addition, we will use the grading of recommendations assessment, development, and evaluation to evaluate the evidence quality. RESULTS: This study will demonstrate an evidence-based review of acupuncture for salpingitis in IVF-ET. CONCLUSION: The study will provide clear evidence to assess the effectiveness and side effects of acupuncture for salpingitis in IVF-ET. TRIAL REGISTRATION NUMBER: INPLASY2020110125.

Benefits of second-look laparoscopy in the management of pelvic inflammatory disease.

OBJECTIVE: To evaluate the benefits of second-look laparoscopy (SLL) in pelvic inflammatory disease (PID). STUDY DESIGN: A 5- year retrospective study conducted at Clermont-Ferrand University Hospital and included all patients who had undergone SLL following a PID. Data collection comprised patient and disease characteristics, type of initial medical or surgical treatment, adhesion (AFS) and tubal (MAGE) scores recorded during SLL and outcomes following subsequent pregnancies. RESULTS: 76 patients who had received SLL were included. A higher rate of severe adhesions was recorded during SLL in patients with stage 3 PID, than for women with stage 1 and 2 (63.6% versus 25%, p = 0.01). A higher rate of Mage scores of 4 were also found in patients with stage 3 PID (25.8% versus 0%, p = 0.001). Multivariate analysis revealed that women at stage 3 are 17 times more likely to have a high level of adhesions than patients at stage 1 (OR [95% CI] = 17.4 [1.7; 1]). A Mage score of 1was found to be associated with higher pregnancy and live birth rates. CONCLUSION(S): SLL seems presents benefits for the preservation of fertility in cases of severe PID with tubo ovarian abcess and may be proposed to patients with stage 3 salpingitis and desire for pregnancy. Further prospective randomized study should be done to confirm these results.

[Low-intensity laser irradiation in the combined treatment of depressive disoreders in patients with chronic salpingo-oophoritis].

This study was designed to evaluate the possibility to use low-intensity laser radiation in combined therapy of somatogenic depressions in patients having gynecological problems, such as inflammatory disease of uterine appendages. It was shown that the combined treatment including administration ofantidepressants significantly accelerated the development of beneficial changes and stabilized depressive manifestations. Inclusion of low-intensity laser irradiation in the combined therapy further improved its positive effect. Nevertheless, the complete recovery could not be achieved in the absence of specific antidepressant treatment despite the alleviation of depressive symptoms.

Tuboovarian abscess caused by Candida in a woman with an intrauterine device.

Candida infection should be considered in an individual with a pelvic abscess that is unresponsive to conventional antibiotic therapy, particularly in the presence of an intrauterine device. We present a case of a tuboovarian abscess caused by Candida species in a woman with an intrauterine device for >10 years. Surgical intervention followed by antifungal therapy resulted in a favorable outcome.

Treatment evaluation of Wharton's jelly-derived mesenchymal stem cells using a chronic salpingitis model: an animal experiment.

BACKGROUND: The present study was conducted to evaluate new methods to repair the reproductive function of the oviduct, thereby allowing gametes to combine and grow in vivo under natural circumstances. METHODS: Sixty pathogen-free female New Zealand rabbits were divided into three groups: a wild-type group, an untreated control group, and a treatment group. Disposable sterile newborn sputum suction tubes were inserted into the urogenital tract to instill an Escherichia coli suspension into the uterine cavity to establish the chronic salpingitis model. Wharton's jelly-derived mesenchymal stem cells (WJMSCs) or normal saline were used to treat this infection via different methods. The therapeutic effect was assessed by evaluating morphology, inflammatory factors, proteinology, and pregnancy outcomes. RESULTS: Oviducts of New Zealand rabbits in the untreated control group showed structural failure and abnormal supermicrostructure of epithelial cells. WJMSCs could partially repair the structure and supermicrostructure of the tubal epithelium. The concentration of tumor necrosis factor (TNF)-α in the untreated control group was significantly higher than that in the wild-type group (P = 0.015). The concentration of TNF-α in the local treatment group was significantly lower than that in the untreated control group (P = 0.011). The expression of oviductal glycoprotein (OVGP) and OVGP mRNA in the wild-type group was significantly higher than those in the untreated control group (P = 0.024 and P = 0.013, respectively). The litter size of the treatment group was 2 ± 2.39 kits, which was higher than that of the untreated control group (P = 0.035). CONCLUSION: Chronic inflammation can destroy the structure of the oviduct and the supermicrostructure of epithelial cells as well as leading to infertility. WJMSC transplantation therapy in rabbits with chronic salpingitis partially restored fertility. WJMSCs also repaired the structure of the tubal epithelium subjected to chronic inflammation, decreased the level of inflammatory factors, and partially restored the secretion level of OVGP.

Tracing GFP-labeled WJMSCs in vivo using a chronic salpingitis model: an animal experiment.

BACKGROUND: The present study was conducted to evaluate the distribution of Wharton's jelly-derived mesenchymal stem cells (WJMSCs) and their repairing function on the oviduct. METHODS: WJMSCs were transfected with the LV3-GFP-PURO lentivirus. Female New Zealand rabbits (n = 24) were divided randomly into control A and B groups and experimental C and D groups to establish inflammation models. Sterile saline solution or WJMSCs were injected into rabbits via ear veins and/or genital tract perfusion once weekly for 3 weeks. All rabbits were humanely sacrificed 1 week after the last perfusion to collect the oviduct, uterus, liver, and bladder for examination. Green fluorescent protein (GFP) and cytokeratin 7 (CK7) were imaged using a Leica Qwin Plus V3 fluorescence confocal microscope and analyzed as mean optical densities in an Image-Pro Plus analysis system. RESULTS: We found that lentivirus expressing the GFP gene produced an efficient transfection. The mean optical density values of GFP and CK7 in the oviducts were higher in the experimental D group than those in the control A and experimental C groups. No GFP fluorescence deposits occurred in the bladder of the control A group or experimental C group. Colocalization of CK7 and WJMSCs was observed in the oviducts in all groups. CONCLUSIONS: WJMSCs exhibited homing characteristics and migrated to the injured oviduct to promote epithelial cell growth. Additionally, local treatment resulted in higher efficiency.

Acute peritonitis and salpingitis associated with streptococcal toxic shock syndrome caused by Lancefield group G alpha-haemolytic Streptococcus dysgalactiae subsp. equisimilis.

The authors treated a patient for what appears to be the first reported occurrence of acute peritonitis and salpingitis associated with streptococcal toxic shock syndrome (STSS). This was caused by Lancefield group G alpha-haemolytic Streptococcus dysgalactiae subsp. equisimilis TKCH2004-001. The isolate showed M protein type stc36 and carried the spegg gene. To the best of the authors' knowledge, the present report represents the first case of STSS complicating acute peritonitis and salpingitis caused by Lancefield group G alpha-haemolytic S. dysgalactiae subsp. equisimilis.

[Chronic salpingo-oophoritis: clinical and physiological rationale for therapeutic application of impulse low-frequency electrostatic field].

Significant alterations in arterial and venous circulation, primarily in the vascular bed of the small pelvis, were detected in 63 patients with chronic salpingo-oophoritis. All the women received intensive therapy with impulse low-frequency electrostatic field (ILFEF). In 52 women the exposure was abdominovaginal, in 11 women the exposure was preceded by placebo procedures. ILFEF produced marked and long-term positive effects (up to 18 months): pain relief, reduction of vegetative anxiety, increased uterine motility, softening and better elasticity of the commissures in the regions of the uterine appendages, normalization of the circulation in the vascular bed of the small pelvis. This therapy is pathogenetically sound as it rests on changes in activity of central regulation resultant from trigger stimulation and normalization of hemodynamics in the vascular bed of the small pelvis (in 76.6%) especially in the veins in response to stimulation of the sympathetic nerves in the inflammation focus.

[Amplipulse-magnetotherapy and iodine-bromine waters in combined treatment of patients with chronic nonspecific salpingo-oophoritis].

Amplipulse-magnetotherapy was used as monotherapy and in combined treatment of 110 patients with chronic nonspecific salpingo-oophoritis (CNSO). Clinical assessment shows that transcerebral amplipulse-megnetotherapy (TAMT) has a positive effects on the course of CNSO, reproductive system and psychoemotional status of the patients. The addition of physical and balneological factors to TAMT enhances and prolongs neurotropic, endocrine, analgetic and anti-inflammatory effects of TAMT.

Recurrent Pelvic Infections and Salpingitis after Perforated Appendicitis.

BACKGROUND: The effect of perforated appendicitis on the adnexa is an issue of concern and controversy. Long-term fertility studies have been conflicting. CASE: We present the case of a patient with chronic pelvic infections, salpingitis, and hydrosalpinx after perforated appendicitis. SUMMARY AND CONCLUSION: Magnetic resonance imaging was helpful in diagnosing a chronically obstructed fallopian tube, likely secondary to the dense adhesions from her previously treated perforated appendicitis. Salpingectomy relieved her symptoms of chronic pain and recurrent infections.

PID: clinical and laparoscopic aspects.

Clinical signs of pelvic inflammatory disease (PID) are not constant and are often limited to slight pelvic pain. Laparoscopy can lead to a rapid and correct diagnosis of PID. Intrapelvic bacteriologic samples can be obtained so as to administer the proper antibiotic. The exact nature of the lesions can be evaluated, and in severe cases, recent abscesses can be treated with good results for fecundity. Because the results in cases of long-standing abscess are not so good, laparoscopy should be performed at the onset of infection and not be reserved until after some weeks of inefficient medical treatment, especially in young women who have not completed their family. In primary chronic salpingitis, the lack of any clinical signs usually leads to a delay in diagnosis until women consult for fertility problems. The ideal point would be to detect some biologic or clinical change that may lead to diagnosis such as a positive anti-Chlamydia trachomatis (CT) serology or, in the future, positive anti-CT Hsp 60 antibody could be the key to detecting and treating silent salpingitis in young women, CT being the main microorganism involved in chronic salpingitis. Screening for C. trachomatis low genital tract infection is mandatory in young people in order to control the epidemic.

Follow-up of patients with tubo-ovarian abscess(es) in association with salpingitis.

The medical records of 143 patients hospitalized with a diagnosis of salpingitis over a five-year period were reviewed. Ninety-three patients had salpingitis without clinical evidence of a tubo-ovarian abscess. Seven (7.5%) of these women had surgical treatment; five of the seven were found to have tubo-ovarian abscesses which had not been detected clinically. Eighty-six of 93 (92.5%) patients with a clinical diagnosis of salpingitis and no abscess responded to medical management alone. Fifty patients had salpingitis and clinical evidence of a tubo-ovarian abscess(es); five of these patients had medical management only, 27 had medical treatment followed by surgery, and 18 had surgery initially before receiving antibiotics. There was a significant difference in age but not in parity between patients with evidence of a tubo-ovarian abscess that was managed medically and those who had surgery. There was no significant difference in surgical procedure performed, chronic symptoms, subsequent gynecologic surgery, or subsequent pregnancy among the groups with an abscess. There was a trend toward more surgical complications among women who had delayed surgical intervention for an abscess. Among women with a unilateral tubo-ovarian abscess, those who had a unilateral salpingo-oophorectomy had a higher pregnancy rate than those who received antibiotics alone. In this study, women with a tubo-ovarian abscess in association with salpingitis did not respond well to antibiotic treatment alone. This may be the most reliable way of distinguishing these patients from women with salpingitis alone or salpingitis in association with a tubo-ovarian inflammatory complex, who, as a group, did respond well to medical management alone.

Reproductive outcome after medical management of complicated pelvic inflammatory disease.

A significant proportion of women with PID will have their disease complicated by a TOC. We conclude that it is appropriate in women with this stage of PID to treat initially with clindamycin and an aminoglycoside. In addition, since more than half of the women will suffer reproductive difficulties, efforts to improve early diagnosis and therapy should continue. Based on our data, an early infertility evaluation is indicated in women wishing to conceive after complicated PID.

Salpingitis isthmica nodosa: results of transcervical fluoroscopic catheter recanalization.

OBJECTIVE: To investigate the role of transcervical tubal catheterization in diagnosis and treatment of proximal tubal obstruction associated with salpingitis isthmica nodosa. DESIGN: Retrospective case study. SETTING: University hospital and outpatient radiology practice. PATIENTS: Fifty-two women with proximal tubal obstruction associated with salpingitis isthmica nodosa. INTERVENTION: Selective salpingography and catheter recanalization using fluoroscopic guidance. MAIN OUTCOME MEASURES: The number of tubes visualized to the fimbria as a percentage of the tubes with proximal tubal obstruction on the initial hysterosalpingogram was determined as a measure of diagnostic efficacy. To evaluate the treatment potential of catheter recanalization, the patients were grouped according to tubal status at the conclusion of the procedure and subsequent pregnancies were evaluated. RESULTS: Forty-seven of 65 tubes (72%) with proximal tubal obstruction were recanalized successfully. Among the 19 women who were able to conceive only via a recanalized salpingitis isthmica nodosa tube, there were 6 live births (32%) and two tubal pregnancies (10%). CONCLUSION: Selective salpingography allows complete tubal diagnosis in almost three fourths of patients with proximal tubal obstruction and salpingitis isthmica nodosa. The radiographic diagnosis of salpingitis isthmica nodosa may be pressure dependent. Intrauterine pregnancies occur via recanalized salpingitis isthmica nodosa tubes, therefore catheter recanalization may be attempted before tubal microsurgery or IVF in patients with proximal tubal obstruction and associated salpingitis isthmica nodosa.

Salpingitis isthmica nodosa: a review of the literature, discussion of clinical significance, and consideration of patient management.

OBJECTIVES: To examine and discuss the pathology, diagnosis, incidence, and patient profile of salpingitis isthmica nodosa and to question its natural history, propose management strategies, and identify areas of promising research. DESIGN: Over 50 studies were reviewed, evaluated, and compared to offer the clinician a foundation on which to generate treatment plans. RESULTS: Salpingitis isthmica nodosa is diagnosed by the pathological presence of isthmic diverticula and may be suggested by characteristic changes on hysterosalpingogram. Its incidence in healthy, fertile women ranges from 0.6% to 11%, but it is significantly more common in the setting of ectopic pregnancy and infertility. There are no studies, retrospective or prospective, that clearly dictate appropriate therapy. CONCLUSION: Given its progressive nature and probable deleterious effects on fertility, we propose that microtubal surgery be the definitive treatment for qualified women who have salpingitis isthmica nodosa.
