Guidelines for biomarker discovery in endometrium: correcting for menstrual cycle bias reveals new genes associated with uterine disorders

2021

Abstract Transcriptomic approaches are increasingly used in reproductive medicine to identify candidate endometrial biomarkers. However, it is known that endometrial progression in the molecular biology of the menstrual cycle is a main factor that could affect the discovery of disorder-related genes. Therefore, the aim of this study was to systematically review current practices for considering the menstrual cycle effect and to demonstrate its bias in the identification of potential biomarkers. From the 35 studies meeting the criteria, 31.43% did not register the menstrual cycle phase. We analysed the menstrual cycle effect in 11 papers (including 12 studies) from Gene Expression Omnibus: t…

Influence of nerve growth factor in endometriosis-associated symptoms

2011

To investigate the role of the nerve growth factor (NGF) in the development of dysmenorrhea/pelvic pain in patients with endometriosis, we performed a prospective, clinical, blind study. Peritoneal fluids (PFs) were obtained from patients with histologically proven endometriosis. Patients with endometriosis were divided into 7 different groups depending on their preoperative pain score and symptomatology: patients with no pain, patients with minimal pain (dysmenorrhea, pelvic pain, or both), and patients with severe pain (dysmenorrhea, pelvic pain, or both) and were used for the neuronal growth assay with cultured chicken dorsal root ganglia (DRG) and for Western blot analyses. Dorsal root …

Histologic analysis of specimens from laparoscopic endometrioma excision performed by different surgeons: does the surgeon matter?

2011

Objective To evaluate whether the amount of ovarian tissue inadvertently removed along with the endometrioma cyst wall at laparoscopy differs in relation to the operating surgeon's level of expertise. Design Multicenter, prospective trial. Setting Four tertiary care university hospitals. Patient(s) Fifty patients, aged 25 to 40 years, with monolateral ovarian endometriomas who underwent laparoscopic excision. Intervention(s) Operation with the stripping technique by surgeons with specific expertise in endometriosis surgery in four centers (groups A, B, C, and D) and by residents with average training in laparoscopic surgery (group E). Main Outcome Measure(s) Histologic examination for the e…

Evaluation of PAI-1 in endometriosis using a homologous immunocompetent mouse model

2018

To analyze the role of PAI-1 (plasminogen activator inhibitor 1) in endometriotic lesion growth, we studied the effect of PAI-1 inhibition by PAI-039 using a homologous mouse model of endometriosis that allows noninvasive monitoring. Endometrial tissue from donor mice was collected, labeled with mCherry adenovirus, and implanted into a subcutaneous pocket on the ventral abdomen of recipient mice. Seven days after transplantation, mice were randomly allocated in two groups and treated once daily for 2 weeks with either vehicle (control group) or PAI-1 inhibitor (PAI-039 group). Endometriotic lesion size generated in recipient mice was monitored by mCherry signal. Animals were euthanized 21 d…

Colorectal infiltrating deep endometriosis: Laparoscopic treatment. A case report

2022

Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum. Because of the thickness of the lesion the patient underwent a segmental laparoscopic colorectal resection with end-to-end anastomosis.

The Inflammatory Feed-Forward Loop Triggered by the Complement Component C3 as a Potential Target in Endometriosis

2021

Copyright © 2021 Agostinis, Zorzet, Balduit, Zito, Mangogna, Macor, Romano, Toffoli, Belmonte, Morello, Martorana, Borelli, Ricci, Kishore and Bulla. The complement system is a major component of humoral innate immunity, acting as a first line of defense against microbes via opsonization and lysis of pathogens. However, novel roles of the complement system in inflammatory and immunological processes, including in cancer, are emerging. Endometriosis (EM), a benign disease characterized by ectopic endometrial implants, shows certain unique features of cancer, such as the capacity to invade surrounding tissues, and in severe cases, metastatic properties. A defective immune surveillance against…

Estudio comparativo, randomizado, ciego, del efecto del pre-tratamiento con análogos de GnRH frente a placebo en pacientes estériles diagnosticadas d…

2016

Introducción La endometriosis se define como la presencia de tejido endometrial fuera de la cavidad uterina, que induce una reacción inflamatoria local. La fisiopatología de esta enfermedad no está completamente establecida, aunque parece que existen factores hormonales, genéticos e inmunológicos implicados. Su prevalencia exacta es desconocida, pero se estima que hasta el 10% de las pacientes en edad reproductiva y el 50% de pacientes con esterilidad la padecen. Esta enfermedad se asocia con dolor y esterilidad. En estas pacientes, las adherencias pueden obliterar las trompas de Falopio e impedir la liberación del ovocito; además, la reserva ovárica podría estar disminuida por la presencia…

Efecto de los análogos de la GnRH sobre la expresión de la aromatasa en células de la granulosa de pacientes con endometriosis

2015

La aromatasa juega un papel fundamental en el establecimiento de la calidad ovocitaria, la cual puede estar alterada en las mujeres infértiles con endometriosis. Por otro lado, la administración prolongada de agonistas de GnRH previo a la fecundación in vitro en estas pacientes, ha demostrado que aumentaba la tasa de gestación aproximadamente cuatro veces. En este estudio se ha comparado la expresión del gen CYP19A1 ( que codifica a la aromatasa) en las células de la granulosa mural (CGM) y en las células de cúmulo (CC), los niveles de estradiol, testosterona y androstenediona en el líquido folicular, la calidad ovocitaria y embrionaria, y la tasa de fecundación de pacientes con endometrios…

Efectos del tratamiento con agonistas dopaminérgicos sobre las lesiones endometriósicas

2014

La prolactina (PRL) es una hormona hipofisaria que desempeña un papel fundamental en diversas funciones reproductivas, fundamentalmente en la lactancia. En situaciones patológicas que están relacionadas con la presencia de adenomas hipofisarios o ingesta de fármacos psicotropos, los niveles de PRL están elevados y afectan a la función gonadal, pues inhiben la secreción de hormonas hipofisarias como la LH o FSH, ocasionando amenorrea (9%), galactorrea (25%) o ambas (70%) (1).La hiperprolactinemia, por lo tanto, es una causa frecuente de infertilidad por anovulación (2). Por otro lado, la endometriosis es una importante entidad patológica ginecológica estrógeno dependiente cuya prevalencia en…

2018

La endometriosis es una enfermedad con elevada prevalencia en la población de mujeres en edad fértil (Goldstein y cols, 1980; Eskenazi y cols, 1997; Gazvani y cols, 2002), que cursa con dolor pélvico crónico, dismenorrea, sangrados irregulares e infertilidad, principalmente (Goldstein y cols, 1980; Eskenazi y cols, 1997). Esta sintomatología empeora la calidad de vida de la paciente (D’Hooghe T y cols, 2006) y genera un gran gasto en términos económicos y sociales (Simoens y cols, 2007), de lo que se deriva su gran importancia. Ésto, unido a las múltiples cuestiones que se desconocen o están en controversia en relación a la génesis de la enfermedad, patogeniam diagnóstico precoz y tratamien…
