- ItemSomente MetadadadosAssociation of serum levels of vascular endothelial growth factor and early ectopic pregnancy(I R O G Canada, Inc, 2013-01-01) Silva, Marcelo Octavio Fernandes da [UNIFESP]; Elito, Julio [UNIFESP]; Daher, S. [UNIFESP]; Camano, Luiz [UNIFESP]; Moron, Antonio Fernandes [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Background: This study evaluated serum vascular endothelial growth factor (VEGF) concentrations in women with ectopic pregnancy (EP), miscarriage, and normal pregnancy (NP). Materials and Methods: This was a case-control study comparing serum VEGF concentrations among 72 women with ectopic pregnancy (n = 35), miscarriage (n = 15), and normal pregnancy (n = 22) matched for gestational age. For the determination of serum VEGF concentration a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) was used. Patients were stratified according to serum VEGF above or below 200 pg/ml. Results: The serum level of VEGF was significantly higher in women with EP (median 211.1 pg/ml; range 5-1,017.0 pg/ml) than in women with normal pregnancy (median 5 pg/ml; range 5-310.6 pg/ml) p < 0.0001. Serum VEGF concentrations did not show any statistically significant difference between women with miscarriage (median 231.9 pg/ml; range 5-813.7 pg/ml) and EP (median 211.1 pg/ml; range 5-1,017.0 pg/ml). When threshold concentrations of serum VEGF level > 200 pg/ml were used, an EP could be distinguished from a normal pregnancy with a sensitivity of 51.4%, a specificity of 90.9%, and a positive predictive value of 90%. Between EP and miscarriage, the sensitivity was 51.4%, specificity 42.8%, and a positive predictive value of 69.2%. Conclusions: Serum VEGF could not distinguish an EP from a miscarriage. However, serum VEGF concentrations could discriminate a normal intrauterine pregnancy (IUP) from an unviable pregnancy (EP or miscarriage).
- ItemSomente MetadadadosAssociation Study of Vascular Endothelial Growth Factor and Polymorphisms of its Gene with Ectopic Pregnancy(Wiley-Blackwell, 2010-02-01) Elito, Julio [UNIFESP]; Daher, Silvia [UNIFESP]; Fernandes da Silva, Marcelo Octavio [UNIFESP]; Higashi Marconi, Natali Maiumi [UNIFESP]; Tezotto Pendeloski, Karen Priscilla [UNIFESP]; Moron, Antonio Fernandes [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)ProblemIn ectopic pregnancy, increased levels of vascular endothelial growth factor are present. the aims of this study were to determine the association between -634C/G, -460T/C, and +936C/T vascular endothelial growth factor (VEGF) polymorphisms and ectopic pregnancy, and to determine whether serum levels of VEGF were affected by genetic factors.Method of studyThis is a case-control study wherein 74 women with a history of ectopic pregnancy in a tertiary care center were compared to 134 post-menopausal controls with two pregnancies and no ectopic pregnancy for the genotyping of VEGF polymorphisms. for 35 patients with the diagnosis of ectopic pregnancy, serum concentrations of VEGF were obtained before the treatment. Genotyping of VEGF (-634C/G, -460T/C, and +936C/T) polymorphisms was performed by PCR, followed by endonuclease digestion. ELISA was performed to evaluate the VEGF serum levels.ResultsThe -634C/G, -460T/C, and +936C/T VEGF polymorphisms were not associated with ectopic pregnancy (P = 0.170, P = 0.285, and P = 0.700, respectively). the serum levels of VEGF were not associated with the genotype of -634C/G, -460T/C, and +936C/T VEGF polymorphisms (P = 0.702; P = 0.347, and P = 0.256, respectively).ConclusionThere was no association between ectopic pregnancy and -634C/G, -460T/C, and +936C/T VEGF polymorphisms. There was no correlation between VEGF genotype and the expression of VEGF in blood samples.
- ItemAcesso aberto (Open Access)Conduta expectante para gravidez tubária íntegra(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 1999-01-01) Kyung Koo, Han [UNIFESP]; Elito Junior, Julio [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)SUMMARY Objective: to evaluate the inclusion parameters in the selection of cases of (tubal) ectopic pregnancy for expectant management and to assess the results. Methods: a prospective study was carried out in 70 patients with unruptured (tubal) ectopic pregnancy, with the objective to carry out an expectant management. The main inclusion criteria in this study were the diameter of the tubal mass, that should be equal or inferior to 5,0 cm, reduced titles of beta-hCG (beta fraction of the chorionic gonadotropic hormone) as compared to the initial value within an interval of 48 h, hemodynamic stability, wishes for future pregnancy and a written permission to participate in the study. All patients were observed in the hospital and when reduction in beta-hCG titles was observed, the patients were discharged from the hospital and followed in the outpatient department, with weekly determinations of beta-hCG until levels lower than 5 mIU/ml were reached, that were considered successful. Results: of the 70 patients who underwent expectant management, only one needed a surgical intervention, because of tubal rupture. The initial values of beta-hCG of the patients ranged from 27 mIU/ml to 41,000 mIU/ml. The average diameter of the tubal mass was 2.9 cm. The presence of free liquid in the peritoneal cavity was observed in 50 patients, small amount in 26 patients, moderate in 16 and large in 8 patients. The ultrasonographic resolution of hematosalpinx occurred in 58 patients and tubal ring was visualized in 12 patients. On color Doppler, 52 were at low risk and 18 at medium risk. Conclusions: the expectant management should be applied with safety in the cases that respect the inclusion criteria, the index of success of this study being 98.6%.
- ItemAcesso aberto (Open Access)Espessura Endometrial como Fator Orientador do Tratamento Clínico da Gravidez Tubária Íntegra(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 2002-06-01) Soares, Roberto da Costa [UNIFESP]; Elito Junior, Julio [UNIFESP]; Han, Kyung Koo [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Purpose: to evaluate the importance of endometrial thickness measurement as an orienting factor for the clinical treatment of unruptured tubal pregnancy. Method: longitudinal observational study, in which the greatest measure of the endometrial thickness was evaluated in millimeters, in the uterine longitudinal axis, through transvaginal ultrasonography. Our study group included 181 patients, all of them respecting the utilization criteria for the clinical treatment (expectant or medicated with methotrexate). Through Student's t test we evaluated the difference between the average thickness of the cases who presented successful results with the treatment and the average of those who failed. Results: the average endometrial thickness of the patients who presented successful results with the medical treatment (31 cases) was 6.4 mm, while the average in the cases of failure was 11.5 mm. These results were significantly different. The average thickness of the successful group with expectant management (128 cases) was 9.0 mm, while the average of those who failed was 9.6 mm. These values were not statistically different. Conclusions: the greatest measure of the endometrial thickness of the uterine longitudinal axis through transvaginal ultrasonography proved to be valuable as a new orienting factor for the medical treatment of patients with a diagnosis of unruptured tubal pregnancy. It may become a useful and auxiliary tool for the recommendation of the use of methotrexate. On the other hand, thickness did not show to be useful as an orienting factor for establishing expectant management.
- ItemAcesso aberto (Open Access)Evolução dos níveis de beta-hCG após tratamento sistêmico da gravidez ectópica íntegra(Associação Médica Brasileira, 1998-03-01) Elito Junior, Julio [UNIFESP]; Nakamura, Mary Uchiyama [UNIFESP]; Camano, L. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: The follow-up of this treatment is done by monitorization of beta-hCG titers. The objective of this study is to evaluate the beta-hCG titers after treatment with MTX. METHODS:. Twenty four women were included in the study. The inclusion criteria were: ectopic pregnancy < 4.5cm, beta-hCG < 15.000mIU/mL, desire of future pregnancy and a written permission to participate in the study. All patients were treated with a single dose of methotrexate (50mg/m² IM). Patients were monitored with beta-hCG titers on days 1, 4 and 7 after the MTX injection, and then weekly until the beta-hCG was less than 25mIU/mL. RESULTS: The variation of the titers of beta-hCG between day 1 and day 4 after MTX was the following: increase 50,0%, decrease 33.3% and in levels less than 25mUI/mL in 16.7% of the cases. The variation of the titers of beta-hCG between day 4 and day 7 after MTX was the following: decline > 15% in 85.7% of the cases, and decline < 15% in 14.3%. There was the necessity of a second dose of MTX in only two cases (8.4%), since the levels of beta-hCG declined less than 15%, in this period. CONCLUSION: The titers of beta-hCG increase in 50.0% of the cases, so it is a frequent event. The understanding of this evolution of beta-hCG titers avoids surgery in the first week of the treatment.
- ItemAcesso aberto (Open Access)Gravidez ectópica após uso de contracepção de emergência: relato de caso(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 2004-10-01) Zucchi, Renato Monteiro [UNIFESP]; Elito Junior, Julio [UNIFESP]; Zucchi, Flavio [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Ectopic pregnancy is the implantation and development of the ovum outside the uterine cavity; it needs a quick diagnosis and an urgent treatment. The presence of the corpus luteum in the ovary that is contralateral to the ectopic pregnancy is presumptive evidence for ovum transmigration, which may be the cause of ectopic pregnancy. In 1994, a multinational clinical trial proved the superiority of levonorgestrel over the existing emergency contraceptive products. In the present study, we describe the case of a 27-year-old woman with ectopic pregnancy and a contralateral corpus luteum after use of hormonal emergency contraception (levonorgestrel), because of failure of the used contraception method (condom). The patient was treated with laparoscopic surgery that was successful.
- ItemAcesso aberto (Open Access)Gravidez ectópica: ensaio iconográfico com enfoque em achados de tomografia computadorizada e ressonância magnética(Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, 2012-10-01) Febronio, Eduardo Miguel [UNIFESP]; Rosas, George de Queiroz [UNIFESP]; Cardia, Patrícia Prando [UNIFESP]; D'Ippolito, Giuseppe [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The objective of the present study is to describe key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain caused by ectopic pregnancy. For this purpose, two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed in female patients with acute abdominal pain caused by proven ectopic pregnancy in the period between January 2010 and December 2011. The imaging diagnosis of ectopic pregnancy is usually obtained by ultrasonography, however, with the increasing use of computed tomography and magnetic resonance imaging in the assessment of patients with acute abdomen of gynecological origin it is necessary that the radiologist becomes familiar with the main findings observed at these diagnostic methods.
- ItemAcesso aberto (Open Access)Índice orientador do tratamento sistêmico da gravidez ectópica íntegra com dose única de metotrexato(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 1998-04-01) Elito Junior, Julio [UNIFESP]; Reichmann, André [UNIFESP]; Nakamura, Mary Uchiyama [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)A prospective study was performed with 42 patients with unruptured ectopic pregnancy, which intended to elaborate an index to orient the systemic treatment with the administration of a single intramuscular dose of methotrexate (50 mg/m²). Patients were monitored with beta-hCG titers on days 1, 4 and 7 after the methotrexate. When the titers of beta-hCG declined more than 15%, between days 4 and 7 after methotrexate, the patients were discharged and had an outpatient follow-up monitored with beta-hCG titers weekly until the titers were less than 5 mIU/ml, which represents success of the treatment. We prepared an index for the systemic treatment with methotrexate, with five parameters: (1) initial titers of beta-hCG; (2) aspects of the image at ultrasound (hematosalpinx, gestational sac, live embryo); (3) size of the mass; (4) free fluid in cul-de-sac; (5) collor doppler. Each parameter received a grade from 0 to 2. Grade 0 represented bad prognosis, favorable parameters received grade 2 and borderline parameters received grade one. The success rate with a single dose of methotrexate was 69.0% (29/42). The color doppler was performed in 20 of the 42 patients; in this group of 20 patients the success rate was 75.0% (15/20). In the 22 patients who were not submitted to the color doppler, the average grade of the score in the successful cases was 6.6, and in the unsuccessful it was 3.1. In the group who underwent the doppler (20 patients) the average was 7.9 in the successful cases and 4.2 in the cases that failed. In the present study the cut-off grade was 5, for most of the patients with grades above 5 had a successful treatment (15/16 - 93.75%), while grades equal or below 5 failed. The score will help to indicate the best cases for the medical treatment. We do not advise the treatment when the grade is equal or below 5. Therefore, we can predict a good evolution of the treatment when the grade is above five.
- ItemAcesso aberto (Open Access)Local management with methotrexate of cesarean scar ectopic pregnancy with live embryo guided by transvaginal ultrasound: A case report(Assoc Medica Brasileira, 2016) Leite, Juliana de Freitas [UNIFESP]; Fraietta, Renato [UNIFESP]; Elito Junior, Julio [UNIFESP]Cesarean scar ectopic pregnancy is a rare type of ectopic pregnancy with high morbidity and mortality. Use of conservative conducts, including medical management with methotrexate, has avoided mutilating surgeries such as hysterectomy and spared the fertility of women. We report the case of a 30-year old patient with a cesarean scar ectopic pregnancy, with a live embryo, who was treated locally with transvaginal ultrasound-guided injection of methotrexate, complemented with various doses of systemic methotrexate.
- ItemSomente MetadadadosMethotrexate for ectopic pregnancy: when and how(Springer, 2014-09-01) Cecchino, Gustavo Nardini [UNIFESP]; Araujo Junior, Edward [UNIFESP]; Elito Junior, Julio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Ectopic pregnancy is the leading cause of maternal death in the first trimester of pregnancy. the dosage of beta fraction of human chorionic gonadotropin (beta-hCG) and improvement of the transvaginal ultrasound allowed an earlier diagnosis and a conservative management. Currently, the use of systemic methotrexate (MTX) proved to be a great alternative with similar success rates and completely non-invasive.We searched for the most relevant articles on the use of MTX in ectopic pregnancy published between 2003 and 2013 in high-impact journals. We performed a strategic search at the Centre for Reviews and Dissemination (CRD), Database of Abstracts of Reviews of Effects (DARE), National Institute for Health Research (NHS), International Prospective Register of Systematic Reviews (PROSPERO), the Cochrane Database of Systematic Reviews (CDSR) and Medical Literature Analysis and Retrieval System Online (MEDLINE) according to the descriptors pregnancy, ectopic and methotrexate, alone or combined.Thus, we based this review on 32 studies that were classified following the grades of recommendation and levels of evidence proposed by the Oxford Centre for Evidence-Based Medicine. Additionally, selected papers were used. Scientific evidence points to a growing trend in the choice of conservative treatment for ectopic pregnancies, whereas expectant management still lacks studies for definitive conclusions. Indeed, the well-established protocols which exhibit a greater number of studies are still based on the single-dose treatment.Considering MTX, it proved to be more effective in cases of low titers of beta-hCG and masses with a small diameter, although there is still no uniformity of these parameters. the choice largely depends on the experience of the medical team and ultimately, on the woman's reproductive desire.
- ItemAcesso aberto (Open Access)Relação entre a espessura endometrial e os níveis do beta-HCG com a resposta ao tratamento da gravidez ectópica com metotrexato(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 2004-07-01) Soares, Roberto da Costa [UNIFESP]; Elito Junior, Julio [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: to evaluate the correlation between the beta-human chorionic gonadotropin (beta-hCG) serum levels and the measurement of the endometrial thickness, in patients under treatment of ectopic pregnancy with methotrexate. METHODS: a prospective study in which the levels of beta-hCG as well as the largest measurement of the endometrial thickness on the uterine longitudinal axis through transvaginal ultrasound were evaluated at 24-48 h intervals in thirty-eight patients with hemodynamic stability, ectopic pregnancy, diameter <3.5 cm, and increased beta-hCG levels. All the patients got methotrexate in a single-dose therapy (50 mg/m² im). We compared the mean values of beta-hCG and endometrial thickness of cases that evolved successfully versus the poor responders using the Student t-test. Afterwards we analyzed the difference of the beta-hCG mean serum values related to the endometrial thickness(<10.0 mm and >10.0 mm) independently of the response to treatment employing the Student t-test. RESULTS: the mean values of beta-hCG and endometrial thickness in patients with successful treatment (28 cases) were 1936.2 mIU/ml and 6.4 mm, respectively, significanlty lower than the mean values for insuccessful cases: 6831.3 mIU/ml and 11.7 mm, respectively (p<0.05). The mean values of beta-hCG in women with endometrial thickness <10.0 mm were 2008.7 mIU/ml, significantly lower than the ones with endometrium >10.0 mm, whose mean values were 6925.9 mIU/ml (<0.05). CONCLUSIONS: the measurement of the endometrial thickness through ultrasound is under the beta-hCG serum values influence, and it showed to be a valuable additional factor to suggest medical treatment with methotrexate in the non-disrupted ectopic pregnancy.
- ItemAcesso aberto (Open Access)Tubal patency following surgical and clinical treatment of ectopic pregnancy(Associação Paulista de Medicina - APM, 2006-01-01) Elito Junior, Julio [UNIFESP]; Han, Kyung Koo [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)CONTEXT AND OBJECTIVE: As there is little information about fertility outcomes among women following clinical treatment (methotrexate and expectant management) and surgery (salpingectomy) consequent to ectopic pregnancy, we evaluate the results from hysterosalpingography subsequent to treatment. The objective was to evaluate contralateral tubal patency using hysterosalpingography following surgery and clinical treatment of tubal pregnancy. DESIGN AND SETTING: This was a prospective study at the Department of Obstetrics of Universidade Federal de São Paulo (UNIFESP), a tertiary center. METHOD: Among 115 patients who underwent hysterosalpingography following surgery and clinical treatment of tubal pregnancy between April 1994 and February 2002, 30 were treated with a single intramuscular dose of methotrexate (50 mg/m²), 50 were followed up expectantly and 35 underwent salpingectomy. RESULTS: The patency of the ipsilateral tube was 84% after methotrexate treatment and 78% after expectant management. In addition, contralateral tubal patency was 97% after methotrexate treatment, 92% after expectant management and 83% after salpingectomy. There were no statistically significant differences between the clinical treatment and surgery groups. CONCLUSIONS: The findings from this study suggest similar contralateral tubal patency rates following salpingectomy, methotrexate treatment and expectant management.
- ItemAcesso aberto (Open Access)Ultra-sonografia transvaginal com doppler colorido para seleção das pacientes para tratamento conservador da gravidez ectópica íntegra(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 1999-04-01) Elito Junior, Julio [UNIFESP]; Reichmann, André [UNIFESP]; Nakamura, Mary Uchiyama [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Purpose: to evaluate the efficacy of color Doppler in the prediction of results of the systemic treatment of unruptured ectopic pregnancy with a single dose of methotrexate. Methodology: twenty patients with a diagnosis of ectopic pregnancy were included in the study. The inclusion criteria were: hemodynamic stability, adnexal mass < 5.0 cm and decline of the titers of beta-hCG less than 15% in an interval of 24 h. The exclusion criteria were hepatic or renal disease and blood dyscrasias. Follow-up was by serial determinations of beta-hCG on days 4 and 7 after the beginning of the treatment, and weekly until the titers were negative. The patients were classified into 3 groups according to color Doppler: high risk (trophoblastic flow covering more than 2/3 of the mass), medium risk (when trophoblastic flow compromised 1/3 to 2/3 of tubal mass) and low risk (when trophoblastic flow covered less than 1/3 of the mass). Results: the success of the treatment with a single dose was 75% (15/20); when a second dose of MTX was used, the success rate was 85%. When comparing color Doppler with the results of the medical treatment, we had high risk in 4 patients and in all the treatment failed; medium and low risk in 16 patients, and in 15 the treatment was successful. Conclusion: color Doppler showing high risk indicated an unfavorable situation for the medical treatment with MTX, while medium and low risk in color doppler were favorable situations for the clinical treatment. However, these results should always be analyzed in association with the evolution curve of the beta-hCG titers.
- ItemAcesso aberto (Open Access)Unruptured tubal pregnancy: different treatments for early and late diagnosis(Associação Paulista de Medicina - APM, 2006-11-01) Elito Junior, Julio [UNIFESP]; Camano, Luiz [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)CONTEXT AND OBJECTIVE: There is evidence that ectopic pregnancies present different behavioral patterns. These distinct evolutions of ectopic pregnancies represent two different natural histories. To evaluate these evolution patterns, we compared patients undergoing medical treatment and expectant management according to their gestational age and initial beta-hCG levels. DESIGN AND SETTING: Prospective study at the Department of Obstetrics of Universidade Federal de São Paulo (UNIFESP), a tertiary center. METHODS: Among 119 cases of unruptured ectopic pregnancies diagnosed from April 1999 to February 2004, 57 received systemic treatment with methotrexate 50 mg/m² (body surface area) intramuscularly and 62 were managed expectantly. In this study we evaluated the beta-hCG levels at presentation and amenorrhea duration. RESULTS: There was a significant difference between the two groups regarding amenorrhea duration and initial beta-hCG levels (p < 0.001). The group with decreasing beta-hCG levels (managed expectantly) had longer amenorrhea (mean: 8.87 ± 1.71 weeks) and lower initial beta-hCG levels (mean: 648.8 ± 754.7 mIU/ml). On the other hand, the group treated with methotrexate had shorter amenorrhea (mean: 6.81 ± 1.88 weeks) and higher beta-hCG levels at presentation (2642.7 ± 2315.1 mIU/ml). CONCLUSIONS: The data suggest that ectopic pregnancies can be categorized into two groups: those with early diagnosis and shorter amenorrhea, increasing or maintained beta-hCG levels over 24 and 48-hour intervals and higher beta-hCG levels requiring medical treatment; and those with late diagnosis and longer amenorrhea, decreased beta-hCG levels over 24 and 48-hour intervals and lower beta-hCG levels requiring expectant management.
