RESUMO

Antecedentes y objetivos: La disfunción tiroidea durante la gestación repercute sobre la salud materno-fetal y puede influir en el desarrollo neurocognitivo del niño. La fisiología tiroidea cambia en el embarazo y obliga a establecer valores de referencia (VR) para cada población y método. Los objetivos fueron determinar dichos VR de hormonas tiroideas (HT) empleando 2 inmunoanálisis, estimar el estado nutricional de yodo y la prevalencia de autoinmunidad tiroidea en nuestra población. Pacientes y métodos: Se seleccionó a 378 gestantes de los sectores sanitarios de Zaragoza y Huesca, con determinación de yoduria, anticuerpos antitiroideos y HT mediante 2 inmunoanálisis diferentes (Beckman y Siemens). Resultados: Yoduria media 187μg/L, mediana 146μg/L. El 78% tomaba suplemento (yoduro potásico) y su consumo se relacionó con mayores niveles de yoduria. El 10,8% tenían anticuerpos antiperoxidasa positivos, el 4,4% antitiroglobulina, el 2,4% ambos y el 4,1% anti-TSHr. No hubo asociación entre yoduria y TSH ni T4L. Los VR de TSH en el primer trimestre fueron Beckman 0,2-4 y Siemens 0,2-3,4 mUI/L. Conclusión: Los VR de HT fueron claramente diferentes a los propuestos por la ATA 2011 pero prácticamente iguales a los descritos en población española utilizando los mismos inmunoanálisis, como propone la ATA 2017. La autoinmunidad tiroidea fue similar a la publicada a nivel nacional e internacional. La media y la mediana de yodurias son de las más elevadas publicadas en España hasta el momento y dependen principalmente de la toma de yoduro potásico para alcanzar los objetivos de la OMS, lo que avala las recomendaciones de suplementación con al menos 150μg de yodo


Background and objectives: Thyroid dysfunction during pregnancy affects maternal and foetal health, which may influence the child's neurocognitive development. The thyroid physiology changes during pregnancy, requiring reference values (RV) to be established for each population and method. The objectives were to determine these thyroid hormone (TH) RV using 2 immunoassays and to estimate the nutritional status of iodine and the prevalence of thyroid autoimmunity in our population. Patients and methods: A total of 378 pregnant women from the health sectors of Zaragoza and Huesca, whose urinary iodine, antithyroid antibody and TH levels were assessed by 2different immunoassays (Beckman and Siemens), were enrolled. Results: The mean urinary iodine concentration was 187μg/l, with a median concentration of 146μg/l. From them, 78% took potassium iodide supplements and their consumption was related to higher levels of urinary iodine; 10.8% were positive for antithyroid peroxidase antibodies, 4.4% for anti-thyroglobulin antibodies, 2.4% for both and 4.1% for anti-TSHr. There was no association between urinary iodine and TSH or T4L. The reference values of TSH in the first trimester were Beckman: 0.2-4 and Siemens 0.2-3.4 mIU/l. Conclusion: The thyroid hormone reference values were markedly different from those proposed by the ATA-2011 guidelines but practically identical to those described in the Spanish population using the same immunoassays, as proposed by the ATA-2017 guidelines. Thyroid autoimmunity was similar to that published nationally and internationally. The mean and median urinary iodine levels are among the highest published in Spain to date and depend mainly on supplementation with potassium iodide to reach the WHO objectives, supporting the recommendations for supplementation with at least 150μg of iodine

RESUMO

El síndrome de Cushing es una enfermedad poco frecuente durante el embarazo, pero se asocia a complicaciones maternas y fetales graves. La etiología más frecuente durante el embarazo es el adenoma suprarrenal, y cifras de cortisol libre en orina por encima de 3 veces el límite superior de la normalidad, por lo general, indican síndrome de Cushing durante el embarazo. El tratamiento de elección es quirúrgico, y el momento ideal para la cirugía es antes del tercer trimestre


Cushing's syndrome is a rare condition during pregnancy, but it is associated with serious maternal and fetal complications. The most common etiology during pregnancy is the presence of an adrenocortical adenoma. Urinary free cortisol over 3 times the upper limit of normal usually indicates Cushing's syndrome during pregnancy. The treatment of choice is surgical, and the ideal time for surgery is before the third trimester
