ABSTRACT
INTRODUCTION:
Family history of thyroid disease (FHTD) constitutes a possible risk factor for congenital hypothyroidism (CH) in the general population; however, FHTD possible relationship with CH in subjects with Down syndrome (DS) has not yet been explored.OBJECTIVE:
To determine whether FHTD is associated with an increased incidence of CH in neonates with DS.METHOD:
Hospital-based case-control study in 220 neonates with DS. Thyroid function tests of 37 infants with DS and positive FHTD (cases) were compared with those of 183 newborns with DS without FHTD (control group). Data were analyzed using multivariate logistic regression analysis and adjusted odds ratios (aORs) with their respective 95 % confidence intervals (CI) were calculated.RESULTS:
Nine newborns with DS in our sample had CH (4.1 %). In the multivariate analysis, FHTD showed an association with CH in neonates with DS (aOR = 8.3, 95 % CI 2.0-34.3), particularly in males (aOR = 9.0, 95 % CI 1.6-49.6). In contrast, newborns with DS without FHTD were less likely to suffer from CH (aOR = 0.4, 95 % CI 0.1-0.8).CONCLUSIONS:
Newborns with DS and FHTD have an eight-fold higher risk for CH, particularly when the index case is male. FHTD detailed evaluation can be an easy and accessible strategy to identify those newborns with DS at higher risk for CH.RESUMEN
INTRODUCCIÓN:
La historia familiar de enfermedad tiroidea (HFET) como factor de riesgo para hipotiroidismo congénito (HC), en síndrome de Down (SD) aún no ha sido explorada.OBJETIVO:
Determinar si la HFET está asociada a mayor riesgo de HC en neonatos con SD.MÉTODO:
Estudio de casos y controles en 220 neonatos con SD. Se compararon las pruebas de función tiroidea (PFT) de 37 con SD e HFET (casos), frente a las PFT de 183 recién nacidos con SD sin HFET (grupo de referencia). Se realizó análisis de regresión logística multivariante y se calculó la razón de momios (RM) y sus respectivos intervalos de confianza del 95 % (IC 95 %).RESULTADOS:
Nueve casos HC (4.1 %). El HC mostró asociación con la HFET (RMa = 8.3, IC 95 % 2.0-34.3), particularmente en los varones (RMa = 9.0, IC 95 % 1.6-49.6). La ausencia de HFET tuvo una RM de protección para HC (RMa = 0.4, IC 95 % 0.1-0.8).CONCLUSIONES:
La HFET puede es una estrategia fácil y accesible para identificar pacientes con SD con mayor riesgo de HC.Palavras-chave
