OBJECTIVE: To determine the effects of a thiazolidinedione (TZD) agonist of peroxisome proliferator-activated receptor (PPAR)-gamma, rosiglitazone, in a baboon model of established endometriosis. DESIGN: Prospective, randomized, placebo-co…

BACKGROUND: Tubo-ovarian abscess involvement of an endometrioma has been reported in cases of patients with polymicrobial sources such as Neisseria gonorrhoeae, Chlamydia trachomatis, and obligate anaerobic bacteria; however, bacterial vagi…

Mannose-binding lectin (MBL) modulates inflammation and usually enhances clearance of apoptotic cells. We observed that the concentration and total amount of peritoneal fluid MBL does not differ in patients with and without endometriosis.

Peritoneal fluid macrophages (PFM) are activated in women with endometriosis, in whom they are thought to mediate or exacerbate inflammation. The effect of PFM on endometrial stromal cells (ESC) was studied using a coculture model to evalua…

OBJECTIVE: To determine the effects of a thiazolidinedione, ciglitazone, in a rat model of endometriosis. DESIGN: Prospective, randomized, placebo-controlled study. SETTING: Experimental surgery laboratory in a university department. ANI…

OBJECTIVE: To investigate the presence of epithelial neutrophil-activating peptide 78 (ENA-78) in peritoneal fluid of women with and without endometriosis and to identify the cells that produce this inflammatory protein. DESIGN: Case-contr…

OBJECTIVE: Interleukin (IL)-1beta, a product of activated peritoneal macrophages, is a central cytokine coordinating neovascularization and monocyte chemotaxis in endometriotic implants. To evaluate the effects of this cytokine on normal en…

Similar to tumor metastases, endometriotic implants require neovascularization to establish, grow, and invade. The peritoneal environment is ideally suited to provide a proangiogenic milieu. Nevertheless, endometriotic lesions are found onl…

RANTES (regulated on activation, normal T cell expressed and secreted) is synthesized by endometrial and endometriotic stromal cells and circulates in peritoneal fluid. Reports indicate that medroxyprogesterone acetate (MPA) is clinically e…

The human endometrium is a complex tissue comprised of different cell types, including epithelial, stromal, inflammatory, perivascular, and blood vessel cells. The hormonal receptivity and distribution of these cell populations change durin…

A complex network of cytokines mediates immunoregulatory responses in the pathogenesis of endometriosis. RANTES (regulated upon activation, normal T cell expressed and secreted) is a chemoattractant for monocytes and T cells. Endometriotic …

OBJECTIVE: To provide a review of the humoral and cellular immunology of endometriosis and to discuss the rationale for future approaches to diagnosis and treatment. DESIGN: Literature survey. RESULT(S): Defective immunosurveillance in wo…

Activated peritoneal macrophages are associated with endometriosis and may play a central role in its aetiology by releasing interleukin-1beta (IL-1beta) in response to refluxed endometrium. Pari passu with the establishment of endometrioti…

A key mechanism underlying the cyclical growth of the endometrium is its ability to regenerate a vascular capillary network. In normal cycling human endometrium, angiogenesis is influenced by both endocrine and paracrine factors. Hormonal m…

Several investigators have noted that hormone-dependent development of endometriosis implants lags behind that of simultaneously analysed eutopic endometrium. With the recent discovery of the oestrogen receptor-beta (ER-beta) isoform, the a…
