ABSTRACT
Abstract

Objectives:

to determine the effectiveness of medical therapy in reducing complications associated with subclinical hypothyroidism during pregnancy.

Methods:

in 2021, a systematic review of available cohort studies was carried out in three databases, with no publication date limit. Study selection and data extraction were performed in duplicate. Random-effects meta-analysis was performed, and odds ratios were calculated, with the corresponding 95% confidence intervals. Cohort risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). The certainty of the evidence was assessed using the GRADE methodology.

Results:

five studies were included for qualitative and quantitative synthesis. A statistically significant relationship was found between medical treatment in pregnant women with subclinical hypothyroidism with respect to spontaneous abortion (p=0.03; OR=0.77; CI95%=0.61-0.97), and no statistically significant relationship was found for delivery preterm (p=0.46; OR=1.11; CI95%=0.85-1.44), nor for abrupt placentae (p=0.56; OR=1.60; CI95%=0.33-7.66). Three studies were at moderate risk of bias, and two were at low risk of bias. In all the results the certainty was very low.

Conclusions:

medical treatment of subclinical hypothyroidism during pregnancy can have a beneficial effect in reducing cases of spontaneous abortion.
RESUMEN
Resumo

Objetivos:

determinar la efectividad de la terapia médica para disminuir las complicaciones asociadas al hipotiroidismo subclínico durante la gestación.

Métodos:

en el 2021 se realizó una revisión sistemática de estudios de cohortes disponibles en tres bases de datos, sin límite de fecha de publicación. La selección de estudios y extracción de datos se realizaron por duplicado. Se realizó metaanálisis de efectos aleatorios y se calcularon los Odds ratio, con los correspondientes intervalos de confanza al 95%. El riesgo de sesgo de las cohortes se evaluó mediante la escala de Newcastle-Ottawa (NOS). La certeza de la evidencia se evaluó con la metodología GRADE.

Resultados:

cinco estudios fueron incluidos para síntesis cualitativa y cuantitativa. Se encontró una relación estadísticamente significativa del tratamiento médico en gestantes con hipotiroidismo subclínico con respecto al aborto espontáneo (p=0,03; OR=0,77; IC95%=0,61-0.97), no se encontró relación estadísticamente significativa para parto pre término (p=0.46; OR=1,11; IC95%=0.85-1.44), ni para abrupto placentae (p=0.56; OR=1,60; IC95%=0.33-7.66). Tres estudios tenían riesgo moderado de sesgo, y dos tenían riesgo de sesgo bajo. En todos los resultados la certeza fue muy baja.

Conclusiones:

el tratamiento médico del hipotiroidismo subclínico durante la gestación puede tener un efecto beneficioso para reducir los casos de aborto espontaneo.
