Prevalencia al nacimiento de hipotiroidismo congénito

Abstract: INTRODUCCIÓN: El hipotiroidismo congénito es la causa más común de discapacidad intelectual susceptible de prevención. En México, el tamiz neonatal de esta enfermedad es obligatorio. La prevalencia al nacimiento de hipotiroidismo congénito fue descrita en México, hace más de 10 años.OBJETIVO: Presentar información actualizada de la prevalencia de hipotiroidismo congénito del Programa de Tamiz Neonatal de la Secretaría de Salud y compararla con la reportada previamente en el país.MATERIALES Y MÉTODOS: Estudio r… Show more

“…The worldwide prevalence of congenital hypothyroidism (CH) is two to three cases per 10,000 live births, but in some populations, such as the Mexican one, it can be up to 7.3 per 10,000 live births. 1 Most primary and permanent cases of CH (80-85%) are attributable to forms of thyroid dysgenesis (TD), including ectopic thyroid (50-60%), thyroid agenesis (20-30%), and thyroid hypoplasia (5%). The etiology of CH is unknown in most patients, although reports of a family history of CH (2%), familial cases of extrathyroidal congenital anomalies, a 1.4 female/male ratio, and the presence of asymptomatic thyroid defects in first-degree relatives collectively suggest that there is a genetic component to this disease.…”

“…Thus, we were unable to rule out the possibility that pathogenic variants of the NKX2-1 gene could be a causal factor for this congenital defect in Mexico, where the prevalence of CH is relatively high. 1 In the present work, we explored whether germline pathogenic variants of NKX2-1 account for a proportion of TD-related CH in patients of Mexican descent.…”

“…Hispanics [1,2], including Mexicans [8], have the highest worldwide birth prevalence of CH. In contrast to the information available in the literature for Caucasian and Asian CH patients [3,6,7,13,16], relatively little is known about the participation of genetic factors in the etiology of CH-TD in Latin-American populations.…”

“…En el mundo, hasta el 2018, se reporta una incidencia de 6.5 por cada 10,000 recién nacidos (McGrath et al, 2018). También se ha descrito que los grupos poblacionales que tienen mayor incidencia de HC son los asiáticos y los hispánicos, entre los que se encuentran clasificadas aquellas personas provenientes de América Latina (Kurinczuk et al, 2002;Hinton et al, 2010;Deladoëy et al, 2011) -Amieva, 2004;Rendón-Macías, 2008;Hinojosa-Trejo et al, 2018), donde se observa un incremento de 1.8 veces durante este periodo (Figura 5).…”
