ABSTRACT
Thyroid pathology is reported internationally in 5-10% of all pregnancies. The overall aim of this research was to determine the prevalence of hypothyroidism and risk factors during the first trimester screening in a Mexican patients sample. We included the records of 306 patients who attended a prenatal control consultation between January 2016 and December 2017 at the Women's Institute in Monterrey, Mexico. The studied sample had homogeneous demographic characteristics in terms of age, weight, height, BMI (body mass index) and number of pregnancies. The presence of at least one of the risk factors for thyroid disease was observed in 39.2% of the sample. Two and three clusters were identified, in which patients varied considerably among risk factors, symptoms and pregnancy complications. Compared to Cluster 0, one or more symptoms or signs of hypothyroidism occurred, while Cluster 1 was characterized by healthier patients. When three clusters were used, Cluster 2 had a higher TSH (thyroid stimulating hormone) value and pregnancy complications. There were no significant differences in perinatal variables. In addition, high TSH levels in first trimester pregnancy are characterized by pregnancy complications and decreased newborn weight. Our findings underline the high degree of disease heterogeneity with existing pregnant hypothyroid patients and the need to improve the phenotyping of the syndrome in the Mexican population.
ABSTRACT
Resumen ANTECEDENTES: La incidencia de agenesia cervical con endometrio funcional se desconoce, aunque se calcula menor a 0.1% en la población general. El pronóstico reproductivo de pacientes con malformaciones müllerianas es limitado y requiere múltiples intervenciones quirúrgicas. CASO CLÍNICO: Paciente primigesta de 21 años, con antecedente de agenesia de cuello uterino y dos tercios superiores de la vagina. Acudió a consulta a las 38.1 semanas de embarazo establecido conforme a la fecha de la última menstruación. Refirió haber concebido de forma espontánea y negó complicaciones durante el embarazo. Se programó para finalizar el embarazo mediante cesárea. El periodo trans y posquirúrgico transcurrió sin complicaciones maternas ni fetales. CONCLUSIÓN: El embarazo espontáneo en pacientes con malformaciones müllerianas debe tratarse a tiempo para asegurar que no surjan complicaciones que pongan en riesgo la vida de la madre y su hijo.
Abstract BACKGROUND: The incidence of cervical agenesis with functional endometrium is unknown, but it's estimated to be less than 0.1% in the general population. The reproductive prognosis in Müllerian malformations is limited and, in most cases, requires multiple surgical interventions to be improved. CASE REPORT: A 21-year-old primiparous patient with a history of agenesis of the cervix and two upper thirds of the vagina. Attended a first-time obstetric appointment at 38.1 weeks of gestation. She refers that the pregnancy was conceived spontaneously and denied complications during pregnancy. A cesarean section was scheduled to end the pregnancy, which had no trans or post-operative maternal-fetal morbidity. CONCLUSIONS: Spontaneous pregnancy in patients with congenital agenesis of the cervix should be addressed in time to ensure a favorable obstetric outcome.
