article 2 Citação(ões) na Scopus Measurement of Serum and Peritoneal Levels of Amyloid Protein A and Their Importance in the Diagnosis of Pelvic Endometriosis(2013) EJZENBERG, Dani; PODGAEC, Sergio; DIAS JR., Joao Antonio; OLIVEIRA, Ricardo Manoel de; BARACAT, Edmund Chada; ABRAO, Mauricio SimoesOBJECTIVE: To evaluate serum and peritoneal concentrations of amyloid protein A in women with endometriosis and to compare them with those of women without endometriosis. STUDY DESIGN: A prospective study evaluated 76 women suspected of having pelvic endometriosis. Fifty-seven women (group A) were confirmed by videolaparoscopy and had their serum and peritoneal amyloid A concentrations measured by procedure of evaluating the peritoneal amyloid A concentration in endometriosis merits further investigation. ELISA. The average levels from group A were compared to those obtained in group B. Group B was composed of 13 women without endometriosis, submitted to elective laparoscopy for tubal ligation. RESULTS: Peritoneal amyloid A concentrations in group A (310.3 +/- 97.8 ng/mL) were higher than those of group B (53.4 +/- 58.2 ng/mL); p = 0.0. However, serum concentrations in groups A (14.01 +/- 32.3 ng/mL) and B (9.5 +/- 15.9 ng/mL) did not differ significantly; p = 0.35. CONCLUSION: The peritoneal amyloid A protein concentration in pelvic endometriosis was higher when compared to normal controls, corroborating the inflammatory nature of the disease. This finding suggests that the procedure of evaluating the peritoneal amyloid A concentration in endometriosis merits further investigation.- Pólipos endometriais: ainda exérese para todos?(2013) GIBRAN, Luciano; CARVALHO, Luiz Fernando Pina; ABRÃO, Mauricio Simões

Design: Case-control study (Canadian Task Force classification II-2). Setting: Tertiary referral hospital. Patient(s): Sixty-four consecutive patients with and without endometriosis. Intervention(s): After videolaparoscopy, patients were divided into three groups: bowel endometriosis (n = 22), retrocervical endometriosis (n = 10), and endometriosis-free women (n = 32). Main Outcome Measure(s): Gene expression of the chemokines that regulate NK (CXCL9, CXCL10, CXCL11, CXCL12, XCL1, and CX3CL1) and T-reg cell activity (CCL17 and CCL21) evaluated by real-time polymerase chain reaction. Result(s): Of the chemokines associated with NK cells, CX3CL1 and CXCL12 expression was statistically significantly greater in the foci of endometriosis compared with the eutopic endometrium in patients and controls. From the chemokines associated with T-reg cells, CCL17 expression was statistically significantly greater in the eutopic endometrium of the patients with rectosigmoid endometriosis compared with the foci of endometriosis or eutopic endometrium of the patients with retrocervical endometriosis or the disease-free women. Conclusion(s): Both T-reg and NK cells mediate inflammatory response and may play a fundamental role in endometriosis by causing an impaired clearing of endometrial cells. Establishing how CCL17, CXCL12, and CX3CL1 modulate this response is essential to understanding inflammatory responses in endometriosis. (Fertil Steril (R) 2013; 99: 1987-93.

bookPart Endometriose(2013) DEUTSCH, Fernanda; ABRãO, Mauricio Simões- Anatomical causes of female infertility and their management(2013) ABRAO, Mauricio S.; MUZII, Ludovico; MARANA, RiccardoThe main female anatomical causes of infertility include post-infectious tubal damage, endometriosis, and congenital/acquired uterine anomalies. Congenital (septate uterus) and acquired (myomas and synechiae) diseases of the uterus may lead to infertility, pregnancy loss, and other obstetric complications. Pelvic inflammatory disease represents the most common cause of tubal damage. Surgery still remains an important option for tubal factor infertility, with results in terms of reproductive outcome that compare favorably with those of in vitro fertilization. Endometriosis is a common gynecologic condition affecting women of reproductive age, which can cause pain and infertility. The cause of infertility associated with endometriosis remains elusive, suggesting a multifactorial mechanism involving immunologic, genetic, and environmental factors. Despite the high prevalence of endometriosis, the exact mechanisms of its pathogenesis are unknown. Specific combinations of medical, surgical, and psychological treatments can ameliorate the quality of life of women with endometriosis. In the majority of cases, surgical treatment of endometriosis has promoted significant increases in fertilization rates. There are obvious associations between endometriosis and the immune system, and future strategies to treat endometriosis might be based on immunologic concepts.
