Identificación de biomarcadores no invasivos de endometriosis mediante metabolómica por RMN

2015

La endometriosis es una enfermedad ginecológica crónica, estrógeno dependiente, asociada a dolor pélvico e infertilidad. Se define por la presencia de tejido endometrial fuera de la cavidad uterina y representa uno de los desórdenes ginecológicos benignos más comunes. Los síntomas de la endometriosis son altamente variables, inespecíficos y comunes en la población general, lo que contribuye a un retraso en el diagnóstico que oscila entre 8-12 años. Actualmente, el “patrón de oro” para el diagnóstico de la endometriosis es la cirugía, normalmente mediante laparoscopia. Sin embargo, se trata de un procedimiento invasivo, que implica riesgos potenciales y no es apropiado para el seguimiento pe…

P–294 Mapping COVID–19 affected genes from blood in a Window of implantation co-expression network reveals a potentially compromised landscape

2021

Abstract Study question Could the transcriptomic and functional landscape of the window of implantation be compromised by SARS-COV–2 infection? Summary answer Some of the main genes and pathways involved in the window of implantation are affected in blood of COVID–19 patients and receptivity could be affected. What is known already There is a concern whether SARS-COV–2 can disrupt assisted reproduction treatments (ARTs) and fertility in short and long terms. In the endometrium, it was found that genes related to the viral infection (ACE2, TMPRSS2/4, CTSL/B) are involved in menstrual cycle progression, especially in the Window of Implantation (WOI). However, there are no studies describing t…

Possible Role of the Posterior Compartment Peritonectomy, as a Part of the Complex Surgery, Regarding Recurrence Rate, Improvement of Symptoms and Fe…

2020

ABSTRACT Study Objective Beside the pain, there are 2 further problems in the management of endometriosis: the high recurrence rate (10% per year) and the high rate of impaired fertility. The objective of this study was to investigate the pathogenesis of these 2 factors. Design This is a retrospective cohort study, and the aim is to evaluate the complete excision of endometriotic lesions, including the posterior compartment of the peritoneum, with regard to postoperative outcome, focusing on relieving pain, increasing fertility rate, and decreasing recurrence rate. Setting Charite-University Clinic, Department of Gynaecology, Endometriosis research Centre. Patients Fifty-four patients were …

Retroperitoneal Squamous Cell Carcinoma Involving the Pelvic Side Wall Arising from Endometriosis: A Case Report

2022

<b><i>Introduction:</i></b> Squamous cell carcinoma (SCC) arising from endometriosis is very rare. Moreover, endometriosis located on the pelvic side wall is uncommon, while its cancerization is quite unusual. We herein report the first case of retroperitoneal SCC arising from endometriosis. <b><i>Case Presentation:</i></b> A case of a 52-year-old woman with retroperitoneal pararectal right mass is presented. The pelvic magnetic resonance imaging showed a retroperitoneal tumor extended to the right pelvic side wall. The neuropelveological examination completed the preoperative assessment, showing a right-sided sciatica and overactive bladder s…

Imbalance between sympathetic and sensory innervation in peritoneal endometriosis

2011

To investigate possible mechanisms of pain pathophysiology in patients with peritoneal endometriosis, a clinical study on sensory and sympathetic nerve fibre sprouting in endometriosis was performed. Peritoneal lesions (n= 40) and healthy peritoneum (n= 12) were immunostained and analysed with anti-protein gene product 9.5 (PGP 9.5), anti-substance P (SP) and anti-tyrosine hydroxylase (TH), specific markers for intact nerve fibres, sensory nerve fibres and sympathetic nerve fibres, respectively, to identify the ratio of sympathetic and sensory nerve fibres. In addition, immune cell infiltrates in peritoneal endometriotic lesions were analysed and the nerve growth factor (NGF) and interleuki…

Acute appendicitis and endometriosis: Retrospective analysis in emergency setting

2013

Introduction. The aim of this study is to evaluate the incidence of appendiceal and pelvic endometriosis in a population with diagnosis of acute appendicitis in an emergency setting. Materials and methods. We carried out a retrospective study in the period between January 2010 and October 2013. We performed 429 appendectomy including 233 in female subjects (54.3%). In all patients of childbearing age, we did β-hCG urine test to rule out the presence of an extra-uterine pregnancy. Results. 127 of 233 patients received a laparoscopic approach (54.5%). The median age was 29 years-old (range 17-68). The diagnosis of appendiceal and/or pelvic endometriosis was performed in 10 patients (4.3%): 9 …

Complement Component 3 expressed by the endometrial ectopic tissue is involved in the endometriotic lesion formation through mast cell activation

2020

AbstractThe pathophysiology of endometriosis (EM) is an excellent example of immune dysfunction, reminiscent of tumor microenvironment as well. Here, we report that an interplay between C3 and mast cells (MCs) is involved in the pathogenesis of ectopic EM. C3 is at the epicenter of the regulatory feed forward loop, amplifying the inflammatory microenvironment, in which the MCs are protagonists. Thus, C3 can be considered a marker of EM and its local synthesis can promote the engraftment of the endometriotic cysts. We generated a murine model of EM via injection of minced uterine tissue from a donor mouse, into the peritoneum of the recipient mice. The wild type mice showed greater amount of…

Dopamine agonist administration causes a reduction in endometrial implants through modulation of angiogenesis in experimentally induced endometriosis

2009

Survival of newly implanted retrograde-shed endometrial tissue during menstruation in an ectopic location requires an adequate blood supply. This suggests that angiogenesis is a prerequisite for the development of endometriosis and that its inhibition may be a target for preventing development. Previous studies have shown that vascular endothelial growth factor (VEGF), a heparin-binding glycoprotein, has an essential role in angiogenesis. The main regulatory factor for angiogenesis appears to be binding of VEGF to its type-2 receptor (VEGFR-2). Cabergoline (Cb2) and other dopamine agonists promote endocytosis of the VEGF receptor-2 (VEGFR-2) in endothelial cells, thereby preventing VEGF-VEG…

Pain experience and social support of endometriosis patients during the COVID-19 pandemic in Germany – results of a web-based cross-sectional survey

2021

Background Endometriosis is a chronic pain condition in premenopausal women. Pain is mainly characterized by pain intensity and may induce disability in all areas of daily life. Nevertheless, pain is influenced by emotional and social factors as well. Social distancing measures or quarantine, as reaction to rapidly rising infections with the COVID-19 virus due to the SARS-CoV-2 pandemic, were implemented across Europe to prevent the spread of the virus and social distancing measures were imposed by the German government by beginning of March 2020 with initiation of the lockdown by the end of March 2020. The objective of this study was to assess, how social distancing measures during the lo…
