Luteinising hormone-releasing hormone (LHRH) analogues administered by a continuous release system produce a more complete and constant inhibition of the pituitary-ovarian axis than do multiple, daily intranasal insufflations or a once dail…

OBJECTIVE: To evaluate the levels of interleukin-1beta (IL1beta) and its inhibitory soluble interleukin-1 receptor type II (IL1R2) in the peritoneal fluid (PF) of normal women and patients with endometriosis suffering from pelvic pain and i…

Endometriosis, commonly associated with intraperitoneal inflammation, is estrogen dependent. Possible links between the immunoinflammatory and endocrine changes observed in endometriotic women have been poorly understood. In this study, we …

PROBLEM: Endometriosis is associated with a chronic inflammatory process, and the increased number of activated peritoneal macrophages is one of the major hallmarks of this process. The medical treatment of the disease, which is based on th…

ObjectiveTo assess whether hormonal agents used in the medical treatment of endometriosis, such as danazol and GnRH agonist, exert direct regulatory action on monocyte chemotactic protein-1 (MCP-1) expression by endometrial epithelial cells…

Endometriosis, a frequent oestrogen-dependent disease believed to result from an aberrant proliferation of endometrial tissue outside the uterine cavity, is associated with an increased expression of monocyte chemotactic protein-1 (MCP-1) i…

ObjectiveTo evaluate the expression of insulin-like growth factor-binding protein-3 (IGFBP-3) in the eutopic endometrium and in endometriotic lesions.DesignRetrospective immunohistochemical study.Patient(s)Twenty-five normal women and 39 wo…

The study of misplaced endometrial cells, which abnormally implant and grow outside the uterine cavity, is of considerable interest for the understanding of the pathophysiology of endometriosis. However, endometriotic cells, particularly ep…

BACKGROUND: Recent data indicate the implication of an IGF/IGFBP/protease system in the development of ectopic implants of endometrium (endometriosis) in the pelvic cavity. MATERIAL AND METHODS: We characterized mitogens and protease(s) aga…

The purpose of this study was to find out differences in the levels of antibodies to distinct antigens in the serum of fertile versus infertile patients with and without endometriosis and to identify these antigens. Blood was collected from…

The pathogenesis of endometriosis, a disease widely believed to arise from an aberrant growth of endometrial tissue outside the uterus, is still unclear. We have previously observed that cytokine-stimulated endometrial cells of women with e…

Accumulated evidence implicates immunological alterations in endometriosis. The purpose of this study was to look for variations in antibodies to distinct antigens in peritoneal fluid of women with and without endometriosis. Peritoneal flui…

Accumulated evidence implicates immunological alterations in endometriosis. The purpose of this study was to look for variations in antibodies to distinct antigens in peritoneal fluid of women with and without endometriosis. Peritoneal flui…

OBJECTIVE: To estimate the concentration and the biologic activity of monocyte chemotactic protein-1 (MCP-1) in the peritoneal fluid (PF) of women with and without endometriosis. DESIGN: A case control study was conducted. SETTING: Gyneco…

Endometriosis is generally associated with an immunoinflammatory process that takes place in the peritoneal cavity of patients. Interleukin (IL)-6, a multifunctional cytokine involved in numerous immunological and proliferative processes, h…

ObjectiveOur purpose was to evaluate monocyte chemotactic protein-1 in the peripheral blood of women with and without endometriosis.Study designFifty-seven patients with endometriosis at laparoscopy done for infertility and pelvic pain were…

ObjectiveLocal secretion of chemotactic factors could contribute to the attraction of macrophages into the peritoneal cavity of women with endometriosis. The purpose of this study was to investigate the ability of endometriotic cells to pro…

ObjectiveTo characterize and purify peritoneal mitogens able to stimulate the proliferation of human endometrial cells in vitro.DesignPeritoneal fluids (PFs) from 50 patients were collected at laparoscopy and pooled (270 mL) for purificatio…

OBJECTIVE: To evaluate in vitro the production of monocyte chemotactic protein-1 (MCP-1) by endometrial cells of patients with and without endometriosis. DESIGN: Primary cultures of stromal and epithelial cells isolated from human endometr…

OBJECTIVE: To review and summarize the state of the art as it relates to the long-term application of GnRH agonists (GnRH-a). DESIGN: A retrospective analysis of the available literature and results and an up-to-date review of a rapidly ev…

OBJECTIVE: To characterize and to purify the growth substances for mouse embryo fibroblasts (NIH/3T3) and endometrial-like cells of the peritoneal fluid of women with endometriosis. DESIGN: A pool of 102 mL of peritoneal fluid (PF) collecte…

Before treatment, the trabecular bone mineral content of the lumbar spine and femoral neck was not significantly different between endometriosis patients and age-matched controls (N = 26). In 17 subjects treated with a monthly goserelin imp…

OBJECTIVE: The evaluation of cholesterol fractions and apoproteins during ovarian suppression by a GnRH agonist implant vs danazol in the treatment of endometriosis. DESIGN: A randomized study in 33 patients comparing goserelin (3.6 mg/4 we…

Ten patients with endometriosis were treated by a continuous subcutaneous infusion of the GnRH agonist buserelin for 6 months. Although serum oestradiol decreased into the menopausal range within 2 weeks after starting treatment, serum LH l…

OBJECTIVE: To characterize the presence of mitogen(s) in the peritoneal fluid (PF). DESIGN: Aliquots of PF aspirated at laparoscopy were assessed for mitogenic activity by the rate of [3H]-thymidine incorporation into the deoxyribonucleic …
