Abstract
Endometriosis is a common gynecological condition with a complex physio-pathological background. This study aimed to assess the role of Rubus idaeus leaf extract (RiDE) as a potential therapeutic agent in reducing the size of the endometriotic lesions and modulate the plasma expression of MMP-2, MMP-9, and TGF-β1. The endometriotic lesions were induced in a rat model by the autologous transplant of endometrium. Thirty-six female rats, Wistar breed, with induced endometriosis, were divided into four groups and underwent treatment for 28 days. The CTRL group received 0.5 mL/day of the vehicle; the DG group received 1 mg/kg b.w./day dienogest; the RiDG group received 0.25 mL/kg b.w./day RiDE and the D+RiDG group received 1 mg/kg b.w./day dienogest and 0.25 mL/kg b.w./day RiDE, respectively. Rats' weight, endometriotic lesion diameter and grade, and plasma levels of MMP-2, MMP-9, and TGF-β1 were assessed before and after treatment. The administration of RiDE in association with dienogest vs. dienogest determined a lower weight gain and a reduction in diameter of the endometriotic lesions. RiDE administration restored MMP2 and MMP9 plasma levels to initial conditions. Rubus idaeus extract may help in reducing dienogest-associated weight gain, lower the size of endometriotic lesions, and have anti-inflammatory effects through MMP2 and MMP9 reduction.

Abstract
Endometriosis is an often painful disease in reproductive-aged women, in which endometrial-like tissue grows outside the uterine cavity. Since the limited current therapeutic alternatives fail in alleviating the symptoms and based on our previous research in in vitro models using the same compounds as the ones used in the present study, we aimed to evaluate the effects of urolithins A (UA) and B (UB) on the growth and survival of endometriotic-like lesions in a murine model of endometriosis. Female BALB/C mice were surgically induced with endometriosis and treated with 2.5 mg kg-1 day-1 intraperitoneal UA or UB. The mice were monitored daily and weighed and the estrous stage was determined. After 28 days of treatment, lesions were counted, measured, excised, and fixed. Both urolithins proved not to affect the estrous cycle or body weight of the mice. UA completely prevented endometriotic-like lesions, while UB diminished the implant volume (p < 0.05). Treatment also reduced epithelial and stromal cell proliferation within the implants (p < 0.001 and p < 0.01, respectively) and apoptosis was enhanced (p < 0.05 and p < 0.01, respectively). These results are promising and reveal that urolithins A and B, separately, have a beneficial effect on the overall endometriotic growth without affecting the body weight or estrous cycle.

Abstract
Endometriosis was induced (autotransplant) in Wistar rats. After 21 days, the rats were randomly divided into two groups (16 female rats each). Control group was forced-fed 0.9% sodium chloride solution, and the ginger group was forced-fed 0.5 mg/100 g of Zingiber officinale Roscoe fresh extract, both by gavage, for 14 days, in addition to their normal diet. After that, an anesthetic dose (ketamine/xylazine) was administered until euthanasia. Peritoneal lavage fluid was collected to evaluate tumor necrosis factor (TNF)-α and interleukin (IL)-6, and autotransplant was measured and excised to evaluate histology. The final mean volumes were larger in the control group (120.92 mm3 ± 78.91) than in the ginger group (40.50 mm3 ± 19.57) (P = .01). The endometriosis foci increased in the control group from 45.10 mm3 ± 29.96 at 21 days postimplantation to 120.92 mm3 ± 78.91 on the day of euthanasia (P = .02). In the ginger group, a slight increase was observed from 38.43 mm3 ± 19.96 to 40.50 mm3 ± 19.57, without statistical difference (P = .83). In addition, a greater increase in growth of the endometriosis foci was found when compared with the control (75.81 mm3 ± 58.95) and ginger groups (2.07 mm3 ± 18.87) (P = .004). No difference was found in TNF-α (P = .51) and in IL-6 (P = .12). The degree of lesion atrophy was higher in the ginger group (1 ± 0.92) than in the control group (2.25 ± 1.16) (P = .03). The ginger extract reduced and atrophied autotransplanted endometriosis foci, but did not reduce IL-6 and TNF-α in the peritoneal lavage fluid.

Long-term outcomes of transvaginal ultrasound-guided aspiration versus traditional conservative surgery as treatment for endometriomas: A retrospective study of cohorts. J Obstet Gynaecol Res 2021; 47:1462-1471.

Abstract
AIM To evaluate if the long-term results (on fertility, need of hysterectomy and persistence of endometriosis) after a minimally invasive intervention (transvaginal ultrasound-guided puncture-aspiration [TUGPA]) for endometriomas are significantly different from performing the traditional conservative surgery (CS) by laparoscopy or laparotomy. METHODS We performed a retrospective study of cohorts on patients undergoing surgery for ovarian endometriomas between January 1998 and April 2015. Cohort 1 consisted of 75 women whose first intervention for endometriomas had been TUGPA. For the cohort 2, we selected a randomized paired case in which the first operation for endometriomas had been CS by laparoscopic or laparotomy (another set of 75 patients). RESULTS There were significantly more recurrences and the time to recurrence and repetition of operations were also significantly shorter in patients with TUGPA. However, there were no significant differences in overall pregnancy/delivery outcomes, in hysterectomy performances, or in endometriosis persistence at the last follow-up visit. There were no significant differences related to the symptoms or to analytical presurgical values but the application of multivariate analysis with binary logistic regression to each dependent variable adjusted for age, symptoms, and presurgical analyses showed a significant risk of recurrence and reoperation of TUGPA versus CS. CONCLUSIONS Those patients with endometriomas who underwent TUGPA (with or without associated medications) had a significant increase in recurrence and the need for reoperation. However, in the long-term there were no significant differences in the results of pregnancy/childbirth, need for hysterectomy, or in the clinical or doubtful persistence of endometriosis.

Acta Histochem 2018; 120:757-767. [PMID: 30195499 DOI: 10.1016/j.acthis.2018.08.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 07/29/2018] [Accepted: 08/16/2018] [Indexed: 12/25/2022]
Abstract
The present prospective study was done to evaluate the effect of silymarin (SMN) on endometriotic-like legions establishment and growth in experimentally-induced endometriosis. For this purpose, the experimental endometriosis was induced in 12 rats and then the animals subdivided into endometriosis-sole and SMN (50 mg kg-1, orally)+endometriosis groups. Following 28 days, the legions establishment, size, Glial cell line-derived neurotrophic factor (GDNF), gfrα1, B Cell Lymphoma 6 (Bcl-6b), Bcl-2, extracellular regulator kinase (ERK1/2) expression ratios, angiogenesis, the apoptosis and fibrosis indices were investigated. The SMN significantly (P < 0.05) decreased the enometriotic-like legions establishment and size, decreased mRNA levels of GDNF, gfrα1, Bcl-6b and Bcl-2 and remarkably diminished GDNF, gfrα1, Bcl-6b and Bcl-2-positive cells distribution/mm2 of tissue versus endometriosis-sole group. The SMN + endometriosis group exhibited a significant (P < 0.05) enhancement in ERK1/2 expression and represented diminished vascularized area and increased apoptosis and fibrosis indices, as well. In conclusion, the SMN by down-regulating GDNF and its receptor gfrα1 expression inhibits GDNF-gfrα1 complex generation and consequently suppresses Bcl-6b expression. Moreover, the SMN by enhancing the ERK1/2 expression and by suppressing the Bcl-2 expression promotes the apoptosis pathway. Finally, the SMN by down-regulating the angiogenesis ratio accelerates apoptosis and consequently induces severe fibrosis in endometriotic-like legions.

Abstract
Women suffered with inflammatory gynecologic diseases, such as endometriosis (EMs) and acute salpingitis (AS) often complained of sub- or infertility, even in those women without obvious macroscopic anatomical pelvic abnormalities also have unexplained infertility. Generally, besides the well-known impairment of classically described oviduct cells caused by inflammatory diseases, such as the ciliated cells, fibroblasts and myofibroblasts, the involvement of the newly identified telocytes (TCs) in disease-affected oviduct tissues and potential pathophysiological roles in fertility problems remain unknown. In this chapter, TCs was investigated in rat model of EMs- and AS-affected oviduct tissues. Results showed inflammation and ischaemia-induced extensive ultrastructural damages of TCs both in cellular body and prolongations, with obvious TCs loss and interstitial fibrotic remodelling. Such in vivo pathological alterations might contribute to structural and functional abnormalities of oviduct tissue and potentially engaged in sub- or infertility. And especially, TCs connected to various activated immunocytes in both normal and diseased tissues, thus might participate in local immunoregulation (either repression or activation) and serve a possible explanation for immune-mediated pregnancy failure. Then, in vitro cell co-culture study showed that uterine TC conditioned media (TCM) can activate mouse peritoneal macrophages and subsequently trigger its cytokine secretion, thus providepreliminary evidence that, TCs are not simply innocent bystanders, but are instead potential functional players in local immunoregulatory and immunosurveillance.

Abstract
Women with endometriosis (EMs) have unexplained infertility. The recently identified telocytes (TCs) might participate in the maintenance of structural and functional integrity of oviduct tissue, but so far the involvement of TCs in EMs-affected oviduct tissue and potential impact on fertility capacity remain unknown. By an integrated technique of haematoxylin and eosin staining, in situ immunohistochemistry and double-labelled immunofluorescence staining and electron microscopy approach, TCs were studied in the autotransplantation Sprague-Dawley rat model of EMs-affected oviduct tissue and in sham control, respectively, together with determination of iNOS, COX-2, LPO and estradiol. TCs were found in perivascular connective tissue and smooth muscle bundles in sham oviduct, with typical ultrastructural features (a slender piriform/spindle/triangular cell body, and one or more extremely long prolongations, emerged from cell bodies and extend to various directions), and specific immunophenotype of CD34-positive/vimentin-positive/c-kit-negative. However, in EMs-affected oviduct tissue (grade III), extensive ultrastructural damage (degeneration, discontinue, dissolution and destruction), significant decrease or loss of TCs and interstitial fibrosis were observed, together with elevated level of iNOS, COX-2, LPO and estradiol, thus suggestive of inflammation and ischaemia-induced TCs damage. Based on TCs distribution and intercellular connections, we proposed that such damage might be involved in structural and functional abnormalities of oviduct, such as attenuated intercellular signalling and oviduct contractility, impaired immunoregulation and stem cell-mediated tissue repair, 3-D interstitial architectural derangement and tissue fibrosis. Therefore, TCs damage might provide a new explanation and potential target for EMs-induced tubal damage and fertility disorders.

Abstract
OBJECTIVE To examine and compare differences, if any, between industry- and nonindustry-sponsored clinical trials on endometriosis and to evaluate the effect of prior published positive preclinical results, or lack thereof, on trial status. DESIGN Cross-sectional study of clinical trials on endometriosis that evaluate drugs/biologicals registered at ClinicalTrials.gov as of July 3, 2013. SETTING University-affiliated hospital. PATIENT(S) None. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Trial status, size, phase, and duration; use of comparator groups; drug classes, number of arms, targeting conditions; and presence or absence of prior positive preclinical results before the launch of the trial. RESULT(S) Eighty trials were identified. The trials sponsored by industry and non-industry have distinct features, differing in trial status, phase, comparator, drug classes, number of arms, trial size, and duration. The phase II/III trials are predominantly industry supported, but these trials frequently use placebo as the comparator. Trials launched without prior published preclinical results do not seem to fare well, although the presence of such studies is no guarantee for success. CONCLUSION(S) Questions as to whether the drug on trial is truly superior to the best available drug or of its cost-benefit profile are overlooked in most cases. There seems to be a deluge of "me-too" drugs with equivocal superiority over existing drugs and cost-benefit profiles. Because clinical trials are time-consuming, no blockbuster drug for endometriosis seems to be on the horizon yet.

Abstract
PURPOSE Evaluate the histological changes in parenchyma's epithelial layer of the uterus and ovarian of rats with induced endometriosis, treated with Uncaria tomentosa extract. METHODS 29 rats with experimental endometriosis, were selected and divided in three groups: The uncaria group received 32 mg/ml of Uncaria tomentosa extract, 1 ml administered daily and the placebo group received 1 ml of saline 0.9% per day, during for 14 days (both groups); the leuprolide group received leuprolide acetate 1mg/kg body weight applied single subcutaneous dose. In the 15th day of treatment the uterine horn and ovaries were removed for histopathological analysis. RESULTS The uncaria group presented nine samples (90%) with immature ovarian follicles, whereas the placebo group did not present any case and in the leuprolide group there were eight rats (88%) with the same change. The placebo group showed mature corpus luteum in all animals, occurring less frequent in uncaria (10%) and leuprolide (22%) groups. The uterine epithelium showed weak proliferative in nine (90%) samples of the uncaria group, in two (20%) animals in the placebo group and seven (77.8%) rats in the leuprolide group. CONCLUSIONS The findings suggest that Uncaria tomentosa has contraceptive effect.

Abstract
PURPOSE The aim of this study was to analyze the changes that occur in rats with experimental endometriosis after treatment with copaiba oil. METHODS Experimental endometriosis was induced in rats. The experimental group received copaiba oil (Copaiferalangsdorffii) orally (0.63 mg/day), and the control group received a 0.9% sodium chloride solution orally (1 ml/100 g of body weight/day). Both groups were treated with gavage for 14 days. After this period, the animals were euthanized, and the implant volume was calculated. The autologous transplants were removed, dyed with hematoxylin-eosin, and analyzed by light microscopy. RESULTS The average final volumes were significantly different between the groups (p=0.007). There was a significant increase (p=0.012) between the initial and final volumes in the control group, whereas treatment with Copaiferalangsdorffii caused a marked reduction in endometrial growth over time (p=0.016). Histologically, 6/11 (55.00%) rats in the experimental group had a well-preserved epithelial layer, and 3 (45.00%) had mildly preserved epithelium. The control group had seven cases (58.30%) of well-preserved epithelial cells and five cases (41.70%) of mildly preserved epithelial cells (p>0.05). CONCLUSION Copaiba oil (Copaiferalangsdorffii) appears to be a promising alternative treatment for endometriosis.

Abstract
OBJECTIVE To evaluate the effects of estrogen treatment in combination with gestrinone on an experimental rat model of endometriosis. METHODS Uterine transplants were attached to the peritoneum of female Wistar rats via a surgical autotransplantation technique. The implanted area was measured during the proestrus phase and after hormonal treatment. We performed morphometric analysis and examined the macroscopic and morphometric alterations of endometrial implants after hormonal treatment in ovariectomized rats. RESULTS The high dose of estrogen caused macroscopic increases in the endometrial implant group compared with other groups, which were similar to increases in the proestrus phase. The low dose showed morphometric development of implants, such as an increase in number of endometrial glands, leukocyte infiltration and mitosis. Gestrinone antagonized both doses of estrogen. CONCLUSION Our findings suggest that gestrinone antagonizes estrogen's effects on rat peritoneal endometrial implants.

Abstract
PURPOSE To evaluate macroscopically the growth degree of self-transplantation of endometriosis in rats. METHODS Forty female rats, after a 7-day period for adpating and evaluating of the estrous cycle regularity, underwent tail abdominal midline laparotomy with 3-cm cuts. The average third of the left uterine horn was removed, 4mm x 4mm patches in liquid environment were made, and self-transplanted in the rat mesenterium with a single stitch, and the endometrial surface of the endometriotic implant facing the lumen of the peritoneal cavity. The rats were programmed to die after three weeks. The abdominal cavity displaying was held and self-transplants were identified and classified. RESULTS The results achieved were: one case for degree 0 (2,5%), three cases for degree 1 (7,5%), eleven cases for degree II (27,5%) and twenty-five cases for degree III (62,5%). CONCLUSION The experimental endometriosis development, through the self-transplantation technique, showed to be most common in degrees 3 and 2 of development.

Abstract
OBJECTIVE To evaluate the effect of interleukin-2 (IL-2) on an experimental model of endometriosis. STUDY DESIGN Double blind and randomized experimental prospective placebo-controlled study. Experimental endometriosis was induced in 66 three-month-old female Wistar rats, by auto-transplanting fragments of endometrium to the peritoneum. After four weeks, the size of each implant was measured in millimeters by laparotomy (L2), and animals were randomly distributed for intraperitoneal administration of human-IL-2, rat-IL-2 or placebo. Four weeks later, the implants were measured (L3) and a second dose was given. After four weeks, endometriosis size was evaluated again (L4). RESULTS We found a reduction of experimental endometriosis at L3 that was only significant in IL-2 treated groups: 20.1% and 30.3% with human-IL-2 and rat-IL-2, respectively (p<0.001 with respect to L2 size), versus a non-significant reduction of 9.0% found in placebo group, but the differences were not statistically significant between groups. The decrease after a second dose (L4) was: 49.8%, 41.8% and 11.4% with human-IL-2, rat-IL-2 and placebo, respectively (p<0.001 in IL-2 groups versus L2 and L3, and p<0.05 in both groups versus placebo at L4). CONCLUSION Intraperitoneal administration of IL-2 reduces experimental endometriosis, and this effect is similar using rat-IL-2 or human IL-2 (non specie-specific effect).

Abstract
Endometriosis, a chronic disease characterized by endometrial tissue located outside the uterine cavity, affects one fourth of young women and is associated with chronic pelvic pain and infertility. However, an in-depth understanding of the pathophysiology and effective treatment strategies of endometriosis is still largely elusive. Inadequate immune and neuroendocrine responses are significantly involved in the pathophysiology of endometriosis, and key findings are summarized in the present review. We discuss here the role of different immune mechanisms particularly adhesion molecules, proteinglycan interactions, and pro-angiogenic mediators in the development and progression of the disease. Finally, we introduce the concept of endometrial dissemination as result of a neuroendocrine-immune disequilibrium in response to high levels of perceived stress caused by cardinal clinical symptoms of endometriosis.

Abstract
The aim of this double-blinded study was to determine changes in leukocyte populations in blood, peritoneal lavage fluid, eutopic and ectopic endometrium after treatment with recombinant rat interleukin-2 (IL-2) using an in vivo experimental model of rat endometriosis. The in vivo model involved transplanting four square fragments of autologous endometrium onto the inner surface of the abdominal wall in 20 Wistar rats. The control group was constituted by 20 sham-operated rats. Both groups were randomly treated (1-month interval treatment) with 2 intraperitoneal doses of glucose solution (5%) that did or did not contain recombinant IL-2, and animals were sacrificed 4 weeks after the last dose of treatment. Blood and peritoneal lavage were obtained during the initial and final laparotomy, whereas eutopic and ectopic endometrium were collected at the end of the experiment. Endometriotic implants were measured in each laparotomy to determine any change in size. Leukocyte populations were analyzed by flow cytometry and immunofluorescence microscopy. Cytometric results were similar in blood and peritoneal lavage. CD25+ and natural killer (NK) cell levels in peripheral blood were lower in rats with endometriosis treated with IL-2, whereas NK cells increased in lavage compared to placebo group. The percentage of macrophages and dendritic cells in blood were higher in all rats treated with IL-2, as well as peritoneal dendritic cells. Implant size of these rats decreased significantly, showing a greater number of activated lymphocytes, macrophages, NK and dendritic cells inside them. In conclusion, recombinant IL-2 induced recruitment of activated leukocytes into endometriotic-like foci, and this was related to a reduction of the implant size, suggesting potential effectiveness of IL-2 as an immunomodulatory agent in this pathology.

Abstract
BACKGROUND To analyze the therapeutic results of one dose of 3 million IU of recombinant interleukin-2 (rIL-2) left intracyst (group I) versus two doses with a 1-month interval (group II) after transvaginal ultrasound (US)-guided drainage of endometriomas under the effect of GnRH analogues. METHODS Prospective and randomized clinical trial (helped by a random number table) at a University Hospital. Twenty-four consecutive patients with endometriomas initially sent to us for laparotomy and conservative surgery for endometriosis were included. INTERVENTIONS Treatment with GnRH analogues every 28 days, 3 doses. Under their effect, one or two transvaginal US-guided punctures were performed in order to aspirate the endometriomas, and 3 million IU of rIL-2 were left in the aspirated cysts each time. MAIN OUTCOME MEASURES CLINICAL RESULTS two menstruations after GnRH analogues. Other secondary outcome measures were: the time until recurrence of cysts, symptoms and CA-125 >35 U/ml, and the need for further medical or surgical treatment. RESULTS They were moderate or good in >50% of cases with one drainage and one dose of 3 million IU of rIL-2 intracyst, but were better with a second drainage and two doses of rIL-2 (25 vs. 58.3% 'good results'). There were fewer recurrences and the interval before recurrence was longer after two doses but differences were not significant. Six patients from group I (50%) and 3 from group II (25%) needed laparotomy and conservative surgery at 17.5 +/- 8.7 months (total time of follow-up = 33 +/- 8.8 months). CONCLUSIONS Treatment of endometriomas with transvaginal US-guided drainage and rIL-2 left in the cysts under endometrial suppressive therapy with GnRH analogues has beneficial effects, improving clinical manifestations and avoiding some surgical therapies. The use of a higher dose of rIL-2 does not produce better results, whereas drainage + rIL-2 twice does.

Abstract
OBJECTIVE To evaluate the possible therapeutic effects of interferon alpha-2b left in the peritoneum after surgery, followed by or not followed by treatment with GnRH analogs. DESIGN A prospective, randomized clinical trial. SETTING University hospital. PATIENT(S) Fifty-two infertile patients with moderate or severe endometriosis. INTERVENTION(S) Laparotomic conservative surgery and either interferon alpha-2b or saline alone left in the pouch of Douglas followed by administration of either GnRH analogs depot or oral indomethacin with transvaginal echography and analysis of CA-125, immunoglobulins, and lymphocyte populations. MAIN OUTCOME MEASURE(S) Recurrence of endometriosis was considered clinically, echographically, and laparoscopically. RESULT(S) Recurrence of endometriosis in four cases without interferon (15.4%) versus 11 patients (42.3%) with interferon alpha-2b. Life table analysis showed significant differences between the groups with and without interferon 21 months after conservative surgery. There were no differences in the recurrence between the groups with or without GnRH analogs. Likewise, there were no significant changes in immunoglobulins and lymphocyte populations among patients with and without recurrence of endometriosis. The patients that received GnRH analogs depot showed a decrease in the number of CD16 and an increase of CD11b cells after treatment. CONCLUSION(S) The use of interferon alpha-2b within the peritoneal cavity after conservative surgery may be inappropriate because it increased later recurrence of endometriosis. The postoperative treatment with GnRH analogs did not significantly reduce the recurrence rate. Immunoglobulins and lymphocyte populations did not change in relation to the recurrence of endometriosis.

Abstract
OBJECTIVE To determine the effect of human interferon (IFN)-alpha-2b on experimental endometriosis in rats. DESIGN Experimental, controlled, double-blind randomized study. SETTING Experimental surgery laboratory in a university department. ANIMAL(S) Ninety-six Wistar rats with endometriosis, induced by transplanting four endometrial fragments into the peritoneal cavity. INTERVENTION(S) One third of the animals served as controls (group A). The others were randomly divided into two groups and were given IFN-alpha-2b either as a single intraperitoneal dose (group B) or as three SC doses (on alternate days) (group C). MAIN OUTCOME MEASURE(S) Laparotomy was performed to measure the size of each implant at various times (days 0, 6, 12, 20, and 120 after treatment). RESULT(S) There were no differences among the groups in the size of the average implants before IFN was administered (17.3+/-6.7, 19.7+/-7.8, and 18.1+/-9.2 mm for groups A, B, and C, respectively). These values were significantly smaller after treatment in group B (14.9+/-8.0 mm) and group C (14.0+/-9.5 mm) than in the control group (17.6+/-7.5 mm) (P<.05). Intraperitoneal IFN produced an initial maximum decrease in the size of the implants (40% reduction on day 6), which diminished until day 20 (20%) and then was maintained on a plateau until day 120 (25%). By contrast, group C showed an initial minimal reduction (13% at day 6), which increased up to day 20 (19%), after which a plateau was reached (23% at day 120). Thus, the effects in both treatment groups were similar in the long term. CONCLUSION(S) Two short regimens of human IFN-alpha-2b reduced the size of experimental endometriosis in rats.
