RESUMO

Background and objectives: Thyroid autoimmunity (TAI) has been associated with a significantly increased risk of miscarriage in women with recurrent pregnancy loss (RPL). The aim of this study was to determine the prevalence of TAI in women with RPL and compare the clinical characteristics of positive and negative TAI women. Materials and Methods: This is a retrospective cross-sectional study; 203 women with RPL were included. Thyroid profile, anti-thyroid peroxidase (TPO-Ab), and anti-thyroglobulin (TG-Ab) antibodies were measured in all participants. Clinical characteristics and causes of RPL were compared between positive and negative TAI. Results: Prevalence of TAI was 14.8%; prevalence of positive TPO-Ab and TG-Ab was 12.3% and 4.9%, respectively. Women with TAI had significantly higher concentrations of thyrotropin (TSH) compared to women without TAI (4.8 ± 3.8 versus 3.1 ± 1.1, p = 0.001). There was no significant difference in age, the number of gestations, miscarriages, state of antiphospholipid antibodies (aPL), or causes of RPL between women that were TAI-positive versus TAI-negative. Prevalence of positive TAI by cause of RPL was: endocrine 7/25 (28%), genetic 1/5 (20%), autoimmune 1/5 (20%), anatomic 8/55 (14.5%), and unexplained cause 13/112 (11.6%). Conclusions: The prevalence of TAI in women with RPL is 14.8%. Women with an endocrine cause have the highest prevalence of TAI.

RESUMO

BACKGROUND: To evaluate the prevalence of Müllerian anomalies (MAs) in a cohort of infertile Mexican women candidates for infertility treatments (intrauterine insemination or IVF (In vitro fertilization) cycles). METHODS: We performed a retrospective observational study on a cohort of consecutive women, who underwent hysteroscopy and laparoscopy as part of the basic infertility workup from 2002 to 2014, at our center. Our aim was to calculate the prevalence of MAs and each subtype. RESULTS: A total of 4005 women were included in the study. The MA prevalence was 4.4% (95% CI; 3.8-5.1; n = 177). Among women with MAs, the prevalence of different MA types was: septate uterus 54.2% (n = 96), arcuate uterus 15.8% (n = 28), bicornuate uterus 10.7% (n = 19), unicornuate uterus 8.5% (n = 15), didelphys uterus 6.2% (n = 11) and hypoplasia/agenesis 3.4% (n = 6), unclassifiable 1.1% (n = 2). Women with MAs who achieved pregnancy were: 33.3% (n = 59). The MA associated with the highest pregnancy rate was septate uterus after hysteroscopic correction, at 38.5% (37/96). CONCLUSIONS: The prevalence of MAs among infertile Mexican women can be considered as low, but not negligible. The septate uterus is the most common MA in women with infertility.

RESUMO

Objetives: The goal of this study was to determine if systemic and peritoneal oxidative stress biomarkers are related to each other and to retrograde menstruation in endometriosis. Methods: Plasma and peritoneal fluid oxidative stress biomarkers and hemoglobin and erythrocytes in peritoneal fluid as retrograde menstruation indicators, were measured in 28 patients with endometriosis and 23 without endometriosis. Results: In the peritoneal fluid, carbonyls and lipohydroperoxides, indicative of protein and lipid oxidative damage, were higher in endometriosis group (21%, p = 0.016 and 46%, p = 0.009, respectively). However, these biomarkers were not different in the blood plasma of both groups, and only protein dityrosine, was increased in the plasma of endometriosis group (31%, p = 0.04). The peritoneal fluid hemoglobin content was not higher in the endometriosis group, nor related to carbonyls and lipohydroperoxides. Additionally, the peritoneal fluid oxidative biomarkers were not correlated with the blood plasma ones, and only malondialdehyde, and ischemia-modified albumin were almost two times higher in peritoneal fluid. Discussion: Our results show a peritoneal and systemic oxidative stress biomarkers increase in endometriosis, but not related to each other, and do not support the hypothesis of an increase in hemoglobin-iron supply towards the peritoneal cavity that causes oxidative damage.

RESUMO

Resumen OBJETIVO: Describir la prevalencia de patología endometrial diagnosticada mediante histeroscopia en pacientes infértiles atendidas en un centro de tercer nivel. MATERIALES Y MÉTODOS: Estudio descriptivo, retrospectivo y observacional efectuado en pacientes con diagnóstico de infertilidad atendidas en el Departamento de Biología de la Reproducción Humana del Instituto Nacional de Perinatología Isidro Espinosa de los Reyes, Ciudad de México. Criterios de inclusión: pacientes infértiles entre 18 y 43 años a quienes se realizó histeroscopia. Criterios de exclusión: pacientes del servicio de Reproducción Humana a quienes no se les realizó histeroscopia o ésta fue fallida. Se utilizó el paquete estadístico para las ciencias sociales (SPSS Statistics) versión 20.0. El análisis estadístico fue descriptivo, con media, desviación estándar o porcentaje. RESULTADOS: Se analizaron los expedientes físicos de 440 pacientes infértiles a quienes se efectuó histeroscopia. Las características demográficas incluyeron edad, IMC, tipo y años de infertilidad. Los hallazgos histeroscópicos fueron: cavidad uterina normal 38.4% y anormal 61.6%, pólipo o endometrio polipoide en 34.3%, malformación mülleriana 13.4%, sinequias 10.7%, leiomioma 7.3%, hiperplasia endometrial 1.4%, adenomiosis 0.9%, cuerpo extraño 0.9%. El 7.5% consiguió el embarazo espontáneo y a 21.8% se les practicaron distintas técnicas de reproducción asistida y se logró el embarazo en 34.3%. CONCLUSIONES: La evaluación de la cavidad uterina es un requisito indispensable del estudio de las pacientes infértiles; en esta búsqueda más de la mitad tuvieron hallazgos histeroscópicos anormales.


Abstract OBJECTIVE: To describe the prevalence of endometrial pathology by hysteroscopy among infertile patients in a tertiary referral hospital, from January 2015 to December 2016. MATERIALS AND METHODS: This is a descriptive, retrospective and observational study. The inclusion criteria were patients between 18 and 43 years of age, who had a hysteroscopy due to infertility. The exclusion criteria were patients from Reproductive Science Department who did not undergo hysteroscopy or for whom it failed. We used the software Statistical Package for the Social Sciences (SPSS) version 20.0 Data in this study were analyzed using mean ± standard deviation or expressed as percentages. RESULTS: Four hundred forty infertile women underwent hysteroscopy. Data from physical patient records were retrieved. Demographic characteristics included age, BMI, type of infertility, years of infertility. Hysteroscopic findings were: normal uterine cavity 38.4%, abnormal 61.6%. Some patients had 2 or more findings: polyp or endometrial polypoid 34.3%, müllerian malformation 13.4%, synechia 10.7%, leiomyoma 7.3%, endometrial hyperplasia 1.4%, adenomyosis 0.9%, foreign body 0.9%. In 7.5%, spontaneous pregnancy occurred, 21.8% underwent assisted reproduction technique, achieving pregnancy in 34.3%. CONCLUSIONS: Assessing of uterine cavity should be an indispensable requirement of infertile patients, since in this study more than half of them had abnormal hysteroscopic findings.

RESUMO

Resumen OBJETIVO: Describir y comparar las consecuencias perinatales de los embarazos logrados por reproducción asistida versus espontáneos. MATERIALES Y MÉTODOS: Estudio observacional, transversal, retrospectivo y analítico. Se incluyeron pacientes que terminaron el embarazo en el Instituto Nacional de Perinatología Isidro Espinosa de los Reyes; se excluyeron las embarazadas con expediente clínico incompleto, terminación del embarazo antes de las 22 semanas. Se analizaron y compararon las principales consecuencias perinatales en ambos tipos de embarazos. El análisis de asociación entre terapia de reproducción asistida y complicaciones perinatales se hizo mediante una regresión logística simple y ajustada por variables confusoras. RESULTADOS: De 448 ciclos iniciados, se analizaron 98 embarazos únicos logrados por reproducción asistida; menor probabilidad para recién nacido pretérmino (p < 0.05) e ingreso a la unidad de cuidados intensivos neonatales (p <0.05) y embarazos múltiples; una probabilidad significativa de amenaza de parto pretérmino versus embarazos espontáneos (p < 0.05). CONCLUSIONES: Se registraron menos complicaciones perinatales en embarazos únicos por reproducción asistida y en embarazos múltiples mayor probabilidad de amenaza de parto pretérmino sin mayor prevalencia de recién nacido pretérmino. La adecuada atención multidisciplinaria previa a la concepción tiene mayor peso en las repercusiones perinatales que la técnica de fertilización asistida por sí misma.


Abstract BACKGROUND: As demand for assisted reproduction techniques has increased, so have concerns about associated perinatal outcomes and whether they are different from spontaneously achieved pregnancies. OBJECTIVE: to describe and compare perinatal outcomes of pregnancies achieved by assisted reproduction versus spontaneous pregnancies. MATERIALS AND METHODS: Observational, cross-sectional, retrospective, analytical study. Pregnancies with resolution within the institute were included; those with an incomplete clinical record, termination of pregnancy before 22 weeks were excluded. The main perinatal results in both types of pregnancies were analyzed and compared. The analysis of the association between assisted reproduction therapy and perinatal complications was made by a simple logistic regression and adjusted for confounding variables. RESULTS: Of 448 cycles initiated, 98 pregnancies achieved by assisted reproduction were analyzed, observing in single pregnancies; lower probability for preterm newborns (p <0.05) and admission to the neonatal intensive care unit (p <0.05) and in multiple pregnancies; a significant probability to present threat of preterm delivery versus spontaneous pregnancies (p <0.05). CONCLUSIONS: There were fewer perinatal complications in single pregnancies for assisted reproduction and in multiple pregnancies a greater probability of threat of preterm delivery without a higher prevalence of preterm newborn, concluding that having an adequate preconceptional multidisciplinary management has a greater weight in perinatal outcomes than Fertilization technique assisted by itself.

RESUMO

Se comparó la evaluación perinatal en dos grupos de estudio en mujeres con edad materna avanzada y embarazo. Estudio retrospectivo y transversal realizado en el Instituto Nacional de Perinatología. Se incluyeron 626 de un total de 778 mujeres con edad > 35 años, las cuales resolvieron su embarazo en el período que va del 1 de enero al 31 de diciembre de 1995. Se clasificaron según la edad en dos grupos: 1) edad materna de 35-39 años y 2) edad materna de > 40 años; éstos a su vez se dividieron de acuerdo a paridad (primigestas y multigestas). Las complicaciones perinatales se clasificaron en: antecedentes personales, complicaciones anteparto e intraparto. Para analizar la asociación entre edad materna y paridad con las complicaciones perinatales, se utilizó la X2 o prueba exacta de Fisher. El porcentaje de mujeres con edad avanzada y embarazo fue 13.6 por ciento. Las principales complicaciones perinatales que se presentaron fueron: prreeclampsia, diabetes gestacional, amenaza de parto pretérmino y ruptura de membranas. Al comparar estas complicaciones por edad y paridad no se encontraron diferencias significativas. Los resultados neonatales fueron adecuados, 90 por ciento de recién nacidos con peso > 2500 gramos y una evolución de Apgar satisfactoria en más de 97 por ciento. La tasa de muerte perinatal independientemente de la edad se ubicó por arriba de 90 por ciento en primigestas y en más de 60 por ciento en multigestas. La evaluación perinatal de la mujer con edad avanzada y embarazo es satisfactorio, siempre y cuando inicie un adecuado control prenatal en etapa temprana de la gestación

RESUMO

El crecimiento aumento en los índices de operación cesárea obliga a realizar un análisis de sus indicaciones. El presente rabajo se realizó en el período de 1085 a 1995, abarcando 11 años de estudio con 28,407 casos. Se analizó la frecuencia e indicaciones clínicas. En relación a los nacimientos, la frecuencia de la operación fue de 40.6 por ciento. Las principales causas fueron: cesárea iterativa 38.2 por ciento, desproporción cefalopélvica 28.1 por ciento, presentación pélvica 23.4 por ciento, enfermedad hipertensiva agregada al embarazo 16.3 por ciento, ruptura prematura de membranas 12.1 por ciento y sufrimiento fetal agudo 10.9 por ciento. La observación acuciosa de las indicaciones en cada institución,podrá proyectar mejores argumentos para la disminución de tan alarmantes índices
