bookPart Endometriose(2017) PODGAEC, Sérgio; NEME, Rosa Maria; KAMERGORODSKY, Gil; MARQUES, Renato Moretti- Female genital tract chronic graft-versus-host disease: A narrative review(2019) MACHADO, Andréa Maria Novaes; HAMERSCHLAK, Nelson; RODRIGUES, Morgani; PICCINATO, Carla de Azevedo; PODGAEC, Sergio; MAUAD, Lenira Maria QueirozAbstract Graft-versus-host disease is one of the main causes of morbidity and mortality in patients submitted to hematopoietic stem cell transplantation. This study reviewed the prevalence of lower female genital tract graft-versus-host disease following hematopoietic stem cell transplantation. A systematic search of the literature for articles published between 1982 and 2015 was performed. A growing number of young women suffering from malignant and benign hematological diseases are receiving allogeneic hematopoietic stem cell transplantation with very satisfactory results in relation to the disease itself. However, these patients face gynecological problems due to graft-versus-host disease. Correct diagnosis and early management are needed to avoid irreversible complications.
- 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.

- 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.
- 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.
