- 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.
- Role of Eutopic Endometrium in Pelvic Endometriosis(2011) CARVALHO, Luiz; PODGAEC, Sergio; BELLODI-PRIVATO, Marta; FALCONE, Tommaso; ABRAO, Mauricio SimoesEndometriosis is defined as the presence of endometrial tissue outside the uterine cavity and is considered a benign gynecologic condition; however, in some cases, it may be aggressive. The pathogenesis of endometriosis is complex and multifactorial. Despite being one of the most widely studied gynecologic diseases, its pathogenesis remains uncertain. The intrinsic endometrial abnormalities thought lobe associated with endometriosis include abnormal expression of genes, modification of endometrial response to hormones such as progesterone; increased nerve density, and oxidative stress. Evaluation of the endometrium in patients with endometriosis is an important line of investigation in the pathophysiology of the disease. It has been suggested that investigation of eutopic endometrium may help to achieve this goal. Presented herein is a literature review and a comprehensive evaluation of the role of eutopic endometrium in pelvic endometriosis. Clinical correlations of the disease are highlighted, with the objective of understanding the role of eutopic endometrium in endometriosis.

- Polymorphisms of ICAM-1 and IL-6 genes related to endometriosis in a sample of Brazilian women(2016) BESSA, Nathalie Zamagni; FRANCISCO, Daniela de Oliveira; ANDRES, Marina de Paula; GUEUVOGHLANIAN-SILVA, Barbara Yasmim; PODGAEC, Sergio; FRIDMAN, CintiaThis study investigated the possibility of K469E (rs5498) and G241R (rs1799969) polymorphisms, in ICAM-1 gene, and G634C (rs1800796), in IL-6 gene, being associated with the occurrence of endometriosis in a sample of Brazilian women. We genotyped 200 women (100 in control group and 100 in endometriosis group) by PCR-RFLP technique for G634C, K469E, and G241R polymorphisms. No significant difference was observed in genotypic frequency between control and endometriosis groups for G634C and K469E polymorphisms (p = 0.61 and p = 0.22, respectively). In addition, no significant difference between stages I-II and III-IV of the disease was found for both SNPs (p = 0.63 and p = 0.24, respectively). All individuals were wild homozygotes for G241R polymorphism. This study suggests that polymorphisms K469E, G241R, and G634C are not associated with increased susceptibility to endometriosis in Brazilian women.
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.- Deep Infiltrating Endometriosis and Activation and Memory Surface Markers and Cytokine Expression in Isolated Treg Cells(2020) GUEUVOGHLANIAN-SILVA, Barbara Yasmin; HERNANDES, Camila; CORREIA, Rodolfo Patussi; PODGAEC, SergioIt is not yet clear whether regulatory T (Treg) cells are active, and whether they play a favorable or adverse effect on endometrial foci implantation. Our aim was to evaluate activation and memory surface markers in Treg isolated from peritoneal fluid (PF) and peripheral blood (PB) of women with deep endometriosis and to assess its cytokine mRNA expression. This case-control study included 49 women with deep infiltrating endometriosis and 20 healthy controls. It was analyzed PF and PB of both groups. Cell surface markers GITR, TNFRII, HLA-DR, ICOS, CTLA-4, CD45RA, and CD45RO were evaluated in Treg (CD3(+)CD4(+)CD25(+)CD127(low)Foxp3(+)) cells by flow cytometry. Additionally, Foxp3, TGF-beta, IL-10, IL-6, and TNF-alpha mRNA expression was assessed by real-time PCR in Treg cells (CD4(+)CD25(+)CD127(dim/-)) isolated using magnetic microbeads. Women with endometriosis had higher percentages of TNFRII+ Treg and CTLA-4+ Treg in their PB, and lower percentages of ICOS+ Treg and CD45RO+ Treg in their PF. The groups displayed no differences in mRNA expression. Regardless of the group, in PF, the percentage of Treg cells overall and of CD45RA+ Treg cells were significantly lower, whereas the percentage of TNFRII+ Treg and CD45RO+ Treg were significantly higher than in PB. Foxp3 and TGF-beta mRNA expression were also higher in PF than in PB. Our results indicated that Treg cells in women with endometriosis have a distinct profile of activation and memory markers, but similar cytokine expression. Moreover, we could observe clearly that Treg cells have distinct profile regarding their origin site.
- Deep Invasive Endometriosis Lesions of the Rectosigmoid May Be Related to Alterations in Cell Kinetics(2015) BASSI, Marco Antonio; ARIAS, Victor; D'AMICO FILHO, Nicolau; GUEUVOGHLANIAN-SILVA, Barbara Yasmin; ABRAO, Mauricio Simoes; PODGAEC, SergioObjectives: The aim of this study was to analyze cell kinetics through expression and apoptosis of topoisomerase 2- (TOP2A), p53, and c-erb2 in rectosigmoid endometriotic lesions and in healthy endometrial tissue and to establish correlations between such findings and clinical data in patients with rectosigmoid endometriosis. Methods: Sixty patients with rectosigmoid endometriosis and 20 control women without endometriosis were included. Immunohistochemical assays were used to measure expression of TOP2A, p53, and c-erB-2. Apoptosis was quantified by directly counting the apoptotic bodies. Findings: The number of lesions was positively correlated with expression of TOP2A in the lesion. There was also significant correlation between the lesions' size and number and cell turnover index. Apoptosis index (AI) was the same for endometriosis lesions and eutopic endometrium. Expression of TOP2A was significantly lower in the endometriosis group compared to the controls. Conclusions: Changes in cell proliferation but not in the AI in rectosigmoid endometriosis are indicative of an imbalance in cell kinetics that may lead to the development of the disease.
- Importância da avaliação da qualidade de vida em pacientes com endometriose(2012) MINSON, Fabíola Peixoto; ABRÃO, Maurício Simões; SARDÁ JÚNIOR, Jamir; KRAYCHETE, Durval Campos; PODGAEC, Sérgio; ASSIS, Fabrício DiasPURPOSE: The present study examined the relationship between some clinical variables and quality of life in a group of patients with endometriosis. METHODS: A total of 130 women seen at a multidisciplinary center specializing in gynecology endometriosis in 2008 participated in the study. This was a cross-sectional study conducted with a convenience sample. The diagnosis of endometriosis was performed by biopsy according to the criteria of the American Society for Reproductive Medicine. The clinical and demographic data were collected from the patients' records. Pain intensity was assessed by a visual numerical scale (0-10), and data on the quality of life were collected using the SF-36. Data analysis consisted of descriptive and inferential statistical tests, Spearman correlation coefficient and Kruskal-Wallis test to compare scores between groups. Nonparametric tests were used for analysis because data were not normally distributed. RESULTS: The patients were 21 to 54 years of age [
or = 34, standard diversion (SD)=6.56], 87% had a university degree, and 75% were married. Seventeen percent reported cases of endometriosis in the family. The average time of onset of symptoms was 4.5 years (SD=6.6), 63% of patients were in stage 3 or 4 of endometriosis 36% of patients had severe or disabling dysmenorrhea and the average intensity of pain according to a visual numerical scale was of 5.6 (SD=3.5). Results suggest that the staging of the disease did not determine the intensity of pain. The time of onset of symptoms also showed no relationship to pain intensity and SF-36 scores. On the other hand, the intensity of pain was associated with lower scores on some scales of the SF-36. CONCLUSION: Patients with endometriosis had lower scores of quality of life than the general population and lower than those of some other diseases.
- 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.
