- Hormonal treatment isolated versus hormonal treatment associated with electrotherapy for pelvic pain control in deep endometriosis: Randomized clinical trial(2020) MIRA, Ticiana A. A.; YELA, Daniela A.; PODGAEC, Sergio; BARACAT, Edmund C.; BENETTI-PINTO, Cristina L.Objective: The aim of the study was to evaluate the clinical effectiveness of complementary treatment using self-applied electrotherapy treatment for pain control over the standard hormonal treatment alone for deep infiltrative endometriosis (DIE). Study design: Multicentre randomized clinical trial. We included a hundred-one participants with DIE in electrotherapy (n = 53) (hormonal treatment + electrotherapy) or control group (n = 48) (only hormonal treatment) by 8 weeks of follow-up. The primary measurement was chronic pelvic pain (CPP) using a visual analogue scale (VAS) and deep dyspareunia. The secondary outcomes were the quality of life by endometriosis health profile (EHP-30) and sexual function by female sexual function index (FSFI). Results: CPP relief was observed only in the electrotherapy group (pre:7.11 +/- 2.40, post:4.55 +/- 3.08, p < 0.001). In terms of deep dyspareunia, improvements were observed for both groups (electrotherapy pre:2.02 +/- 0.54-1.36 +/- 0.96, p < 0.001; control pre:1.95 +/- 0.86-1.68 +/- 0.82, p = 0.006). Considering the secondary outcomes, a higher total score post-treatment for the EHP-30 was noted in both groups. Regarding sexual function, there was a statistically significant improvement in the FSFI score for the electrotherapy group (p < 0.001), with an increase in the scores for lubrication and pain domains (p = 0.013 and p < 0.001). Conclusions: Electrotherapy treatment using transcutaneous electrical nerve stimulation proved to be a good complementary option for pain control, showing benefits in the reduction of CPP and deep dyspareunia and improving patient's quality of life and sexual function.
bookPart Endometriose: modelo experimental(2014) PODGAEC, Sergio; ABRãO, Maurício Simões; JúNIOR, José Maria Soares; SIMõES, Manuel de Jesus; BARACAT, Edmund Chada- Cognitive Behavioral Therapy in Endometriosis, Psychological Based Intervention: A Systematic Review(2022) DONATTI, Lilian; MALVEZZI, Helena; AZEVEDO, Bruna Cestari de; BARACAT, Edmund Chada; PODGAEC, SergioIntroduction Endometriosis is an inflammatory disease that affects women of reproductive age, causing pain and the possibility of infertility. Endometriosis was associated to low life quality and research shows the impact of endometriosis in several areas of life, justifying how these patients are more likely to develop depression, anxiety, and stress. Objective The aim of the present systematic review was to explore the field of psychology in endometriosis, identifying studies that used the cognitive behavioral therapy technique as a treatment for endometriosis and chronic pelvic pain. Methods The keywords used were Endometriosis and Behavioral Therapy; Behavioral Disciplines and Activities ; Cognitive Behavioral Therapy ; Mental Health ; Psychological Techniques ; Psychology ; Psychotherapy ; Mental Health Services ; and the search was performed in the following databases: PubMed/Medline, Scielo, Lilacs, and Capes. The study followed the PRISMA guidelines and all studies whose intervention strategy used was related to cognitive-behavioral therapy were considered. Results Of the 129 articles found, only 5 were selected, and it was possible to identify that the psychological intervention whose approach brought cognitive-behavioral therapy techniques promoted a decrease in the sensation of pain, improvements in the scores of depression and stress, and significant changes in aspects of quality of life such as vitality, physical and social functioning, emotional well-being, control, and autonomy. Conclusion Cognitive-behavioral therapy can be very promising to take care of the emotional side of those who have endometriosis However, the present systematic review highlights the need to develop more structured studies with consistent, clear and replicable methods to reach a psychological intervention protocol for patients who live with this gynecological-physical-emotional condition.
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.- Nanotechnology for the treatment of deep endometriosis: uptake of lipid core nanoparticles by LDL receptors in endometriotic foci(2019) BEDIN, Alessandra; MARANHAO, Raul C.; TAVARES, Elaine R.; CARVALHO, Priscila O.; BARACAT, Edmund C.; PODGAEC, SergioOBJECTIVE: Rapidly dividing cells in multiple types of cancer and inflammatory diseases undergo high low density lipoprotein (LDL) uptake for membrane synthesis, and coupling an LDL-like nanoemulsion, containing lipid nanoparticles (LDE) to a chemotherapeutic agent efficiently targets these cells without significant systemic effects. This was a prospective exploratory study that evaluated the uptake of a radioactively labeled LDE emulsion by receptors of endometriotic foci and the capacity of the LDE for cellular internalization. METHODS: The lipid profile of each patient was determined before surgery, and labeled LDE were injected into fourteen patients with intestinal or nonintestinal endometriosis. The radioactivity of each tissue sample (intestinal endometriosis, nonintestinal endometriosis, healthy peritoneum, or topical endometrium) was measured. RESULTS: The group with intestinal endometriosis presented higher levels of plasma LDL but lower LDE uptake by foci than the nonintestinal group, suggesting less cell division and more fibrosis. The uptake of LDE was highest in the topical endometrium, followed by the healthy peritoneum, and lowest in the endometriotic lesion. Since the endometriotic foci showed significant LDE uptake, there was likely increased consumption of LDL by these cells, similar to cells in cancers and inflammatory diseases. Plasma cholesterol levels had no influence on LDE uptake, which showed that the direct delivery of the nanoemulsion to target tissues was independent of serum lipoproteins. There were no significant differences in the parameters (p > 0.01) because of the small sample size, but the findings were similar to those of previous studies. CONCLUSION: Nanotechnology is a promising therapeutic option for surgery and hormonal blockage for deep endometriosis, with a lower complication rate and no systemic side effects.
- Protocol of randomized controlled trial of potentized estrogen in homeopathic treatment of chronic pelvic pain associated with endometriosis(2016) TEIXEIRA, Marcus Zulian; PODGAEC, Sergio; BARACAT, Edmund ChadaBackground: Endometriosis is a chronic inflammatory disease that causes difficult-to treat pelvic pain. Thus being, many patients seek help in complementary and alternative medicine, including homeopathy. The effectiveness of homeopathic treatment for endometriosis is controversial due to the lack of evidences in the literature. The aim of the present randomized controlled trial is to assess the efficacy of potentized estrogen compared to placebo in the treatment of chronic pelvic pain associated with endometriosis. Methods/design: The present is a randomized, double-blind, placebo-controlled trial of a homeopathic medicine individualized according to program 'New Homeopathic Medicines: use of modern drugs according to the principle of similitude' (http://newhomeopathicmedicines.com). Women with endometriosis, chronic pelvic pain and a set of signs and symptoms similar to the adverse events caused by estrogen were recruited at the Endometriosis Unit of Division of Clinical Gynecology, Clinical Hospital, School of Medicine, University of Sao Paulo (Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo - HCFMUSP). The participants were selected based on the analysis of their medical records and the application of self-report structured questionnaires. A total of 50 women meeting the eligibility criteria will be randomly allocated to receive potentized estrogen or placebo. The primary clinical outcome measure will be severity of chronic pelvic pain. Statistical analysis will be performed on the intention-to-treat and per-protocol approaches comparing the effect of the homeopathic medicine versus placebo after 24 weeks of intervention. Discussion: The present study was approved by the research ethics committee of HCFMUSP and the results are expected in 2016.
- Endometriosis doubles the risk of sexual dysfunction: a cross-sectional study in a large amount of patients(2017) FAIRBANKS, Flavia; ABDO, Carmita Helena; BARACAT, Edmund C.; PODGAEC, SergioIntroduction: Endometriosis affects several aspects of a woman's life, including sexual function, but which specific aspects of sexual function remains unclear.Methods: A cross-sectional study was performed involving 1001 women divided into two groups, according to the presence or absence of endometriosis. We assessed sexual function, anxiety and depression of patients and correlated these findings with symptoms, locations and types of endometriosis and the affected domains of sexual function. Eighteen completed the forms incorrectly, 294 women (29.9%) were excluded due to severe anxiety and depression. One hundred and six patients had symptoms that could have any relation to endometriosis, so they were also excluded. The final cohort was composed of 254 patients with endometriosis and 329 patients without the disease. Sexual function score was assessed using the female sexual quotient (FSQ); Beck inventories were used to assess anxiety and depression.Results: Patients with endometriosis were affected in all phases of sexual response: desire, sexual arousal, genital-pelvic pain/ penetration and orgasm/ sexual satisfaction. In the overall assessment, 43.3% of patients with endometriosis had sexual dysfunction, while the population without endometriosis sexual dysfunction occurred in 17.6% of women.Conclusions: Patients with endometriosis have more than twice sexual dysfunctions as compared to women without the disease.
- Transcriptional changes in the expression of chemokines related to natural killer and T-regulatory cells in patients with deep infiltrative endometriosis(2013) BELLELIS, Patrick; BARBEIRO, Denise Frediani; RIZZO, Luiz Vicente; BARACAT, Edmund Chada; ABRAO, Mauricio Simoes; PODGAEC, SergioObjective: To evaluate the expression of chemokines that regulate natural killer (NK) and T-regulatory (T-reg) cell activity in eutopic and ectopic endometrial tissue samples from endometriosis patients. 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.

- Foxp3 expression in deep rectosigmoid endometriosis lesions and its association with chronic pelvic pain(2014) PODGAEC, Sergio; BARBEIRO, Denise Frediani; GUEUVOGHLANIAN-SILVA, Barbara Yasmin; BELLELIS, Patrick; ABRAO, Mauricio Simoes; BARACAT, Edmund ChadaEndometriosis is a benign gynecological disease that is related to immune response alterations. T regulatory cells modulate immune response, and Foxp3 seems to be the best marker of these cells. This study evaluated Foxp3 mRNA expression in eutopic endometrium from women with endometriosis and healthy controls, and its expression in deep rectosigmoid endometriosis lesions, one of the more aggressive types of the disease. Foxp3 expression was higher in lesions than in eutopic endometrium in the two groups. Moreover, eutopic endometrium Foxp3 expression of women with endometriosis was associated with chronic pelvic pain and cyclic urinary pain.
- Evaluation of CA-125 and soluble CD-23 in patients with pelvic endometriosis: a case-control study(2012) RAMOS, Ivana Maria de Luna; PODGAEC, Sergio; ABRAO, Mauricio Simoes; OLIVEIRA, Ricardo de; BARACAT, Edmund ChadaObjective: To evaluate serum concentrations of CA-125 and soluble CD-23 and to correlate them with clinical symptoms, localization and stage of pelvic endometriosis and histological classification of the disease. Methods: Blood samples were collected from 44 women with endometriosis and 58 without endometriosis, during the first three days (1st sample) and during the 7th, 8th and 9th day (2nd sample) of the menstrual cycle. Measurements of CA-125 and soluble CD-23 were performed by ELISA. Mann-Whitney U test was used for age, pain evaluations (visual analog scale) and biomarkers concentrations. Results: Serum levels Of CA-125 were higher in endometriosis patients when compared to the control group during both periods of the menstrual cycle evaluated in the study. This marker was also elevated in women with chronic pelvic pain, deep dyspareunia (2nd sample), dysmenorrhea (both samples) and painful defecation during the menstrual flow (2nd sample). CA-125 concentration was higher in advanced stages of the disease in both samples and also in women with ovarian endometrioma. Concerning CD-23, no statistically significant differences were observed between groups. Conclusion: The concentrations of CA-125 were higher in patients with endometriosis than in patients without the disease. No significantly differences were observed for soluble CD-23 levels between groups.
